              % Senior Subordinated Debentures due
- --------------------------------------------------------------------------------
 
The   % Senior Subordinated Debentures due     (the "Debentures") of Del Webb
Corporation (the "Company") are unsecured senior subordinated obligations of the
Company. Interest on the Debentures is payable on          and          of each
year commencing          , 1998. The Debentures are not redeemable prior to
         . Thereafter, the Debentures are redeemable at any time at the option
of the Company, in whole or in part, at the redemption prices set forth herein.
The Company is required to offer to repurchase all outstanding Debentures at 101
percent of their principal amount plus accrued interest promptly after the
occurrence of a Change of Control (as defined).
 
The Debentures are unsecured obligations of the Company and are subordinated in
right of payment to all existing and future Senior Debt (as defined) of the
Company. The Debentures will be pari passu with the Company's $100 million of
9 3/4% Senior Subordinated Debentures due 2003, $100 million of 9% Senior
Subordinated Debentures due 2006 and $150 million of 9 3/4% Senior Subordinated
Debentures due 2008 (collectively, the "Outstanding Debentures") and the
covenants applicable to the Debentures are substantially similar to those
applicable to the Outstanding Debentures. The Indenture pursuant to which the
Debentures will be issued (the "Indenture") will restrict the ability of the
Company and certain of its subsidiaries to incur additional indebtedness. After
giving effect to the offering of the Debentures and the anticipated repayment of
debt with the net proceeds thereof, as of March 31, 1998 the Company would have
had Senior Debt of $115.8 million outstanding under the Company's $400 million
senior unsecured revolving credit facility (the "Credit Facility") and
short-term lines of credit and $20.8 million of other Senior Debt and would have
had the capacity to borrow $55.0 million of additional Senior Debt under the
Credit Facility and short-term lines of credit. In addition, the Company
conducts all of its operations through subsidiaries, and the Debentures will be
effectively subordinated to all existing and future obligations of the Company's
subsidiaries. At March 31, 1998 the Company's subsidiaries had $72.9 million of
indebtedness. See "Description of the Debentures."
 
The Debentures will be issued in book-entry form and represented by one or more
global debentures (a "Global Debenture") in fully registered form, without
coupons, which will be deposited with a custodian for, and registered in the
name of a nominee of, The Depository Trust Company ("DTC") in New York, New
York, as depositary for the accounts of its participants. Beneficial interests
in the Global Debentures will be represented, and transfers thereof will be
effected, only through book-entry accounts maintained by DTC and its direct and
indirect participants. Initial settlement for the Debentures will be made in
immediately available funds and secondary market trading activity in beneficial
interests therein will therefore settle in such funds. Except in limited
circumstances, Certificated Debentures (as defined) will not be issued in
exchange for beneficial interests in the Global Debentures. See "Description of
Debentures -- Book-Entry, Delivery and Form." The Debentures have been approved
for listing on the New York Stock Exchange.
 
SEE "RISK FACTORS" BEGINNING ON PAGE S-10 FOR A DISCUSSION OF CERTAIN FACTORS
THAT SHOULD BE CONSIDERED BY PROSPECTIVE PURCHASERS OF THE DEBENTURES.
 
THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES

ACCURACY OR ADEQUACY OF THIS PROSPECTUS SUPPLEMENT OR THE PROSPECTUS. ANY

                               equal to 101 percent of the aggregate principal
                               amount of the Debentures, plus accrued and unpaid
                               interest to the date of purchase. The Company

                               ten percent of the principal amount of the

                               regarding these mandatory offers to purchase the
                               Debentures, see "Description of the
                               Debentures -- Certain Covenants -- Change of
                               Control" and "-- Maintenance of Consolidated
                               Tangible Net Worth."
 
Certain Covenants............  The Indenture will contain certain covenants
                               which, among other things, limit the incurrence
                               of additional Indebtedness, the payment of
                               dividends, the making of certain other
                               distributions and the ability to enter into
                               certain transactions with affiliates or merge,
                               consolidate or transfer substantially all of the
                               Company's assets. The covenants applicable to the
                               Debentures are substantially similar to those
                               applicable to the Outstanding Debentures. See
                               "Description of the Debentures -- Certain
                               Covenants."
 
Use of Proceeds..............  The Company anticipates using the net proceeds
                               from the sale of the Debentures to repay a
                               portion of the indebtedness outstanding under the
                               Credit Facility. The Company currently intends to
                               reborrow under the Credit Facility, subject to
                               compliance with covenants that limit available
                               borrowings thereunder, to fund development of new
                               projects and land acquisitions and for other
                               general corporate purposes. As a result of the
                               restrictions in the Credit Facility, the Company
                               expects that, after repayment of a portion of the
                               Credit Facility with the estimated net proceeds
                               of the Offering, approximately $252.2 million of
                               the $400 million Credit Facility will not be
                               available. However, the Company is negotiating an
                               amendment to the Credit Facility to revise
                               certain debt-related covenants and increase the
                               amount of the Credit Facility to $450 million,
                               all of which would be available, subject to
                               compliance by the Company with the revised
                               covenants. See "-- Recent Developments -- Recent
                               Community Development Activities" and "Use of
                               Proceeds."

(1) In fiscal 1996, in connection with the adoption of Statement of Financial
    Accounting Standards ("SFAS") No. 121, the Company incurred a non-cash loss
    from impairment of southern California real estate inventories in the amount
    of $65.0 million pre-tax ($42.3 million after tax) related to the valuation
    of its Sun City Palm Desert active adult community. Exclusive of the
    non-cash loss, the Company's net earnings for fiscal 1996 were $34.5
    million, or $1.96 per diluted share.
 
    Net earnings for fiscal 1993 include a $12.8 million loss from discontinued
    operations (primarily additional loss provisions related to the Company's
    discontinued land development projects), a $0.5 million extraordinary gain
    from the extinguishment of debt on a discounted basis and a $20.0 million
    increase in net earnings as a result of a cumulative effect of an accounting
    change from the adoption of SFAS No. 109. Net earnings for fiscal 1997
    include a $1.3 million extraordinary loss from the early extinguishment of
    debt.
 
(2) The ratio of earnings to fixed charges is calculated by dividing earnings by
    fixed charges. For this purpose, "earnings" means earnings from continuing
    operations before income taxes plus (a) fixed charges and interest
    amortization minus (b) capitalized interest. "Fixed charges" means total
    interest whether capitalized or expensed (including the portion of rent
    expense representative of interest costs), plus debt-related fees and
    amortization of deferred financing costs. Earnings in fiscal 1996 were
    inadequate to cover fixed charges by $21.6 million due to a $65.0 million
    non-cash loss from impairment of southern California real estate inventories
    incurred in connection with the Company's adoption of SFAS No. 121. See Note
    12 to the Company's Consolidated Financial Statements included in its Annual
    Report on Form 10-K for the fiscal year ended June 30, 1996.
 
(3) The information shown is adjusted for the sale of the Debentures and the
    anticipated use of the estimated net proceeds therefrom. The net proceeds
    are anticipated to be used to repay a portion of the indebtedness
    outstanding under the Credit Facility. See "Use of Proceeds."
 
(4) At December 31, 1997, $72.6 million of this Senior Debt and real estate and
    other notes was subsidiary debt.
 
(5) Net new orders are reduced by cancellations. The Company recognizes revenues
    at close of escrow.
 
(6) A majority of the backlog at December 31, 1997 is currently anticipated to
    result in revenues in the 12 months ending December 31, 1998. However, a
    majority of the backlog is contingent, primarily upon the availability of
    financing for the customer and, in certain cases, sale of the customer's
    existing
 
                                       S-6
<PAGE>   7
 
    residence or other factors. Also, as a practical matter, the Company's
    ability to obtain damages for breach of contract by a potential home buyer
    is limited to retaining all or a portion of the deposit received. In the
    years ended June 30, 1995, 1996 and 1997 and the six months ended December
    31, 1996 and 1997, cancellations of home sales orders as a percentage of new
    home sales orders written during the period were 18.3%, 17.2%, 17.1%, 19.8%
    and 14.7%, respectively.
 
(7) "EBIT" means earnings from continuing operations before (i) interest, (ii)
    income taxes and (iii) non-cash loss from impairment of southern California
    real estate inventories. For this purpose, "interest" means interest expense
    plus interest amortization less interest income.
 
(8) "EBITDA" means earnings from continuing operations before (i) interest, (ii)
    income taxes, (iii) the non-cash loss from impairment of southern California
    real estate inventories, (iv) allocation of non-cash common costs (excluding
    interest amortization) and (v) depreciation and other amortization. See Note
    (7) above for the definition of "interest" as used here.
 
(9) "Interest incurred" means total interest, whether capitalized or expensed,
    on debt plus debt-related fees and amortization of deferred financing costs.

     Total net new orders for the Company's third quarter ended March 31, 1998
increased 18.1 percent to 1,934 net new orders, compared with 1,638 net new
orders for the comparable quarter in the prior year. Net new orders at
operations that were selling homes throughout the third quarter of both fiscal
1998 and fiscal 1997 increased 16.1 percent in the 1998 quarter.
 
     The increase in total net new orders was largely due to the commencement of
Florida community operations in January 1998 and net new order activity at three
smaller-scale communities in Arizona and California in the current fiscal year.
These increases were partially offset by declines attributable to the recently
completed Terravita, Coventry Homes' southern California operations and Sun City
Tucson.
 
     The increase in net new orders at operations that were selling homes
throughout the third quarter of both fiscal 1998 and fiscal 1997 was largely due
to increases at Sun City Roseville and Sun City Palm Desert, which management
believes may indicate continued improvement in the California real estate
economy. In addition, both of these California communities benefited from the
introduction of new product offerings, which management believes had a positive
impact on new orders. Management believes that the increase in net new orders at
the Sun Cities Las Vegas is due to the continued strength of the Las Vegas
market. At Sun City Hilton Head, management believes that the increase in net
new orders may be partially due to the fact that important commercial and
service-related businesses have announced development plans for the area
adjacent to Sun City Hilton Head. Coventry Homes' net new orders increased as a
result of increases in Phoenix and Las Vegas.
 
     Home closings for the Company's third quarter totaled 1,270, a 13.4 percent
decrease from 1,467 closings for the comparable quarter in the prior year. This
decrease in home closings and the resulting decrease in net earnings were
primarily due to a lower beginning backlog and to decreased home closings at
Terravita, Coventry Homes' southern California operations and Sun City Tucson,
reflecting the completion of those operations.

NEW COMMUNITY DEVELOPMENTS
 
     The Company strives to continue master-planned community development and
conventional homebuilding operations in geographic areas in which it has been
successful. As described below, the Company has recently commenced development
of several successor communities in key markets as well as several new
communities. See "Use of Proceeds."
 
     Sun City Lincoln Hills.  Sun City Lincoln Hills is located close to and is
planned as the successor to Sun City Roseville. Sun City Lincoln Hills is
located on 2,300 acres and is planned for 5,600 homes. The Company broke ground
at this community in April 1998 and has scheduled the commencement of sales
activities for the fourth quarter of fiscal 1999 and the first home closings for
the first quarter of fiscal 2000.
 
     Anthem Las Vegas.  The Company's Anthem Las Vegas project will include an
active adult community, Sun City Anthem, planned as the successor to Sun City
Summerlin. Sun City Anthem is planned for 9,000 homes to be located on 3,400
acres. The Company broke ground at this community in November 1997 and has
scheduled commencement of sales activities for July 1998 and the first home
closings for the third quarter of fiscal 1999.
 
     In addition to Sun City Anthem, Anthem Las Vegas is planned for a
non-age-restricted golf community, Anthem Country Club. Planned for 1,500 homes
on 950 acres, Anthem Country Club broke ground in November 1997 and has
scheduled the commencement of sales activities for July 1998. Anthem Las Vegas
will also have a conventional homebuilding component, Coventry Anthem, currently
planned for 1,400 homes on 300 acres.
 
     Anthem Las Vegas is planned for a total of 4,700 acres. The 1,900 acres
owned by the Company for Anthem Las Vegas were acquired through a land exchange
with the Bureau of Land Management ("BLM"). The Company continues to work toward
completion of an exchange with the BLM for the remaining acres, substantially
all of which will be used for Sun City Anthem.
 
     Anthem Phoenix.  Anthem Phoenix (formerly the Villages at Desert Hills),
located on 5,600 acres of land near Phoenix, is planned to include a
non-age-restricted country club community and a conventional homebuilding
component and may also include an active adult community at a later date. Anthem
Phoenix is currently planned for 14,500 homes. The Company began offsite
development in November 1997 and has scheduled commencement of sales activities
in fiscal 1999 and currently anticipates that home closings will begin in fiscal
2000.
 
     Sun City at Huntley.  Sun City at Huntley, located in Huntley, Illinois
(near Chicago) is planned for 5,000 homes on 1,800 acres. The Company broke
ground at this community in April 1998 and has scheduled sales activities to
begin in September 1998 and the first home closings for the fourth quarter of
fiscal 1999.
 
     Recent Florida Acquisition.  In January 1998 the Company entered the active
adult community business in Florida by acquiring two communities -- the Spruce
Creek communities -- located near Ocala, Florida. These communities are located
on 839 acres and are planned for 2,922 homes, of which 367 have been sold and
delivered as of March 31, 1998. At that date, the Spruce Creek Communities had a
backlog of 256 homes.
 
INCREASE IN LEVERAGE
 
     Substantial cash expenditures are required at the early stages of community
development. Because the Company has a number of new communities undergoing
initial development, it anticipates a significant increase in its leverage
during approximately the next two years, prior to receipt of significant
revenues from home closings at the new communities. Except as identified above,
the Company does not currently anticipate substantial expenditures for any new
community during the next two years. In the ordinary course of business the
Company may consider selective acquisitions of land for future communities.
 
     The above discussions contain forward looking statements. No assurance can
be given that the Company will be able to meet the timing goals described above,
that the Company will be able to obtain the additional land for Anthem Las Vegas
or to do so on acceptable terms, as to the success of any of these communities
or as to the Company's future land acquisitions or the timing of and
expenditures for its new communities. See "Risk Factors."
 
                                       S-9
<PAGE>   10
 
                                  RISK FACTORS
 
     Prospective purchasers should carefully consider the factors set forth
below as well as the other information included or incorporated by reference in
this Prospectus Supplement or the Prospectus before deciding to purchase the
Debentures.
 
FINANCING AND LEVERAGE
 
     As a result of the Offering and anticipated future borrowings under the
Credit Facility, the Company expects to be more highly leveraged than it has
been in recent years. The Company's degree of leverage from time to time will
affect its interest incurred and capital resources, which could limit its
ability to capitalize on business opportunities or withstand adverse changes. If
the Company is at any time unable to service its debt, refinancing or obtaining
additional financing may be required and may not be available or available on
terms acceptable to the Company.
 
     Real estate development is dependent on the availability and cost of
financing. In periods of significant growth, the Company will require
significant additional capital resources, whether from issuances of equity or by
incurring additional indebtedness. The availability and cost of debt financing
is dependent on governmental policies and other factors outside the control of
the Company.
 
     The Credit Facility restricts, and the indentures for the Outstanding
Debentures contain provisions that may restrict, the indebtedness the Company
may incur. As a result of the restrictions in the Credit Facility, the Company
expects that, after repayment of a portion of the Credit Facility with the
estimated net proceeds of the Offering, approximately $252.2 million of the $400
million Credit Facility will not be available. The Company is negotiating an
amendment to the Credit Facility to revise certain debt-related covenants and
increase the amount of the Credit Facility to $450 million, all of which would
be available, subject to compliance by the Company with the revised covenants.
If the amendment negotiations are not successfully concluded and the Company
cannot obtain sufficient capital from other sources to fund its development and
expansion expenditures, its projects may be delayed, resulting in cost increases
and adverse effects on the Company's results of operations. No assurance can be
given as to whether any such amendment will be available to the Company, as to
the terms on which it might be available or as to the availability or cost of
any future financing.
 
FUTURE COMMUNITIES AND NEW GEOGRAPHIC MARKETS
 
     The Company's communities will be built out over time. Therefore, the
medium- and long-term future of the Company will be dependent on the Company's
ability to develop and market future communities successfully. Acquiring land
and committing the financial and managerial resources to develop a large-scale
community on that land involve significant risks. Before these communities
generate any revenues, they require material expenditures for, among other
things, acquiring large tracts of land, obtaining development approvals and
constructing project infrastructure (such as roads and utilities), large
recreation centers, golf courses, model homes and sales facilities. It generally
takes several years for such communities to achieve cumulative positive cash
flow.
 
     The Company is in the early stages of developing an active adult community
near Chicago, Illinois, the Company's first four-season active adult community,
and commenced operations near Ocala, Florida in January 1998 through the
acquisition of a local active adult community developer. The Company will incur
additional risks, to the extent it develops communities in climates or
geographic areas in which it does not have experience or develops a different
size or style of community, including acquiring the necessary construction
materials and labor in sufficient amounts and on acceptable terms, adapting the
Company's construction methods to different geographies and climates and
reaching acceptable sales levels at such communities. Among other things, the
Company believes that a significant portion of the home sales at its active
adult communities is attributable to referrals from, or sales to, residents of
those communities. The extent of such referrals or sales at new communities,
including communities developed in other areas of the country, may be less than
the Company has enjoyed at the active adult communities where it currently sells
 
                                      S-10
<PAGE>   11
 
homes, and there will be challenges attracting potential customers from areas
and to a market in which the Company has not had significant experience.
 
GOVERNMENTAL REGULATION AND ENVIRONMENTAL CONSIDERATIONS
 
     The Company's business is subject to extensive federal, state and local
regulatory requirements, including with respect to development activities and
land exchanges, the broad discretion that governmental agencies have in
administering those requirements and "no growth" or "slow growth" political
sentiments, which have been increasing in recent years, all of which can
prevent, delay, make uneconomic or significantly increase the cost of its
developments. If the land exchange for Anthem Las Vegas is not completed, that
project would have to be reduced in scope and reconfigured, which could affect
the timing and potential profitability of the project, and the Company may have
to dispose of the property acquired for the exchange at less than its purchase
price. In addition, environmental concerns and related governmental requirements
have affected and will continue to affect all of the Company's community
development operations.
 
     In connection with the development of the Company's communities and other
real estate projects, particularly those located in California, numerous
governmental approvals and permits are required throughout the development
process, and no assurance can be given as to the receipt (or timing of receipt)
of these approvals or permits. In addition, third parties can file lawsuits
challenging approvals or permits received, which could cause substantial
uncertainties and material delays for the project and, if successful, could
result in approvals or permits being voided.
 
     The occurrence of any of the above factors could have a material adverse
effect on the Company.
 
COMPETITION
 
     All of the Company's real estate operations are subject to substantial
competition. The Company competes with numerous national, regional and local
homebuilders and developers, some of which have greater financial resources than
the Company.
 
     With the exception of the recently acquired Spruce Creek Communities near
Ocala, Florida, the Company believes that it maintains a leading position within
the active adult community market in each of the metropolitan areas in which it
has an active adult community currently generating revenues. For the Company's
active adult communities, there are varying degrees of direct and increasing
competition from businesses engaged exclusively or primarily in the sale of
homes to buyers age 55 and older and from non-age-qualified, master-planned
communities in these areas. The Company competes with new home sales and resales
at these other communities, as well as with resales of homes in its own
communities. The Company believes there may be significant additional future
competition in active adult community development, including competition from
national homebuilders and conventional community developers.
 
     The Company believes the major competitive factors in active adult
community home purchases include location, lifestyle, price, value, recreational
facilities and other amenities and builder/developer reputation. The Company
believes that the major competitive factors in the conventional homebuilding
part of its business include location, home quality, price, value, design and
mortgage financing terms.
 
GEOGRAPHIC CONCENTRATION
 
     The Company's primary business operations are particularly concentrated (in
terms of both invested capital and profitability) in the Phoenix and Las Vegas
metropolitan areas. Its entire operations are comprised of a limited number of
communities in seven states. The Company's geographic concentration and limited
number of projects may create increased vulnerability to regional economic
downturns or other adverse project-specific matters.
 
     A significant number of purchasers at the Company's active adult
communities in Arizona, Nevada and southern California are from southern
California. Those communities have been and may in the future be affected by
conditions in the southern California real estate market and the southern
California economy generally.

CYCLICAL NATURE OF REAL ESTATE OPERATIONS AND OTHER CONDITIONS GENERALLY
 
     The Company's communities are subject to real estate market conditions
(both where its communities and conventional homebuilding operations are located
and in areas where its potential customers reside), the cyclical nature of real
estate operations, general national economic conditions and changing demographic
conditions.
 
     The Company's communities are long-term projects. Sales activity at the
Company's communities varies from period to period, and the ultimate success of
any community cannot necessarily be judged by results in any particular period
or periods. A community may generate significantly higher sales levels at
inception (whether because of local pent-up demand in the area or other reasons)
than it does during later periods over the life of the community. Revenues and
earnings of the Company will also be affected by period-to-period fluctuations
in the mix of product and home closings among the Company's communities and
conventional homebuilding operations and by sales of commercial land and
facilities at the Company's communities.
 
     The Company's real estate operations also depend upon the availability and
cost of mortgage financing. An increase in interest rates, which may result from
governmental policies and other factors outside the control of the Company, may
adversely affect the buying decisions of potential home buyers and their ability
to sell their existing homes.
 
CONSTRUCTION LABOR AND MATERIALS COSTS
 
     The Company has from time to time experienced shortages of materials or
qualified tradespeople or volatile increases in the cost of certain materials
(particularly increases in the price of lumber and framing, which are
significant components of home construction costs), resulting in longer than
normal construction periods and increased costs not reflected in the prices of
homes for which home sale contracts had been entered into up to one year in
advance of scheduled closing. Generally, the Company's home sale contracts do
not contain, or contain limited, provisions for price increases if the Company's
costs of construction increase. The Company relies heavily on local contractors,
who may be inadequately capitalized or understaffed. The inability or failure of
one or more local contractors to perform may result in construction delays,
increased costs and loss of some home sale contracts.
 
NATURAL RISKS
 
     Some of the Company's communities are subject to natural risks including
earthquakes, floods, tornados, hurricanes and significant rainfall. Some of
these conditions have had a significant impact on the Company's operations in
the past. Such natural risks could have a material adverse impact on the
development of and results of operations for the community affected and the
Company in the future.
 
SUBORDINATION OF DEBENTURES
 
     The Debentures will be subordinate and junior in right of payment to all
Senior Debt of the Company. At March 31, 1998, on a pro forma basis after giving
effect to the sale of the Debentures and the anticipated use of the estimated
net proceeds therefrom, the Senior Debt of the Company, which does not include
any subsidiary indebtedness, would have been $136.5 million (including $9.0
million of letters of credit). Since the Company conducts all of its operations
through subsidiaries, the Debentures will be effectively subordinated to all
existing and future obligations of the Company's subsidiaries, even though
subsidiary obligations do not constitute Senior Debt. At March 31, 1998 the
Company's subsidiaries had $72.9 million of indebtedness.
 
     Because of the subordination of the Debentures, in the event of any payment
or distribution of the assets of the Company in any dissolution, insolvency,
bankruptcy or other similar proceeding, holders of Senior Debt must be paid in
full before the holders and beneficial owners of Debentures may be paid and
amounts otherwise payable to the holders of Debentures will be paid to the
holders of Senior Debt until the Senior Debt is paid in full. By reason of this
subordination, in the event of the dissolution, insolvency or bankruptcy of the
Company, holders and beneficial owners of the Debentures may recover less,
ratably, than holders of Senior Debt and other creditors of the Company, or may
recover nothing. In addition, the Company is required to
                                      S-12
<PAGE>   13
 
stop making payments of principal and interest on the Debentures if there is a
continuing default with respect to any Senior Debt that would permit the holders
of such Senior Debt to accelerate payment of that debt and the Trustee receives
notice of the default from a holder of such Senior Debt entitled to give that
notice.
 
MARKET FOR DEBENTURES
 
     Although the Debentures have been approved for listing on the New York
Stock Exchange, the Debentures are a new issue of securities, have no
established trading market and may not be widely distributed. Accordingly, no
assurance can be given as to the liquidity of, or trading market for, the
Debentures. No assurance can be given that the Debentures will not trade below
their face amount.
 
YEAR 2000 ISSUE
 
     The year 2000 issue is the result of computer programs being written using
two digits (rather than four) to define the applicable year. Computer programs
that have time-sensitive software may not recognize dates beginning in the year
2000, which could result in miscalculations or system failures. The large
majority of the computer software used by the Company is already year 2000
compliant. The Company is currently working to resolve any remaining potential
impact of the year 2000 on the processing of date-sensitive information by the
Company's computerized information systems. Based on current information, the
costs of addressing potential problems are not expected to have a material
adverse impact on the Company's financial position, results of operations or
cash flows in future periods. However, the failure of the Company, its
contractors, suppliers or financial institutions to resolve the year 2000 issue
in a timely manner could result in a material financial risk. The Company is
assessing the effect of a failure of its contractors, suppliers or financial
institutions to adequately address the year 2000 issue.

                                USE OF PROCEEDS
 
     The net proceeds of the Offering, estimated at approximately $195.3
million, will be used to repay a portion of the indebtedness outstanding under
the Credit Facility. At March 31, 1998, $288.0 million of borrowings, bearing a
weighted average interest rate of 7.87 percent per year, were outstanding under
the Credit Facility. See "Capitalization." These borrowings were incurred to
fund development of existing and new projects and for other general corporate
purposes or to refinance indebtedness incurred for those purposes.
 
     The Company currently intends to reborrow under the Credit Facility to fund
development of new projects and land acquisitions and for other general
corporate purposes. As a result of the restrictions in the Credit Facility, the
Company expects that, after repayment of a portion of the Credit Facility with
the estimated net proceeds of the Offering, approximately $252.2 million of the
$400 million Credit Facility will not be available. However, the Company is
negotiating an amendment to the Credit Facility to revise certain debt-related
covenants and increase the amount of the Credit Facility to $450 million, all of
which would be available, subject to compliance by the Company with the revised
covenants. See "Risk Factors -- Financing and Leverage."
 
                                 CAPITALIZATION
 
     The following table sets forth the consolidated capitalization of the
Company at March 31, 1998 and as adjusted to give effect to the sale of the
Debentures and the use of the estimated net proceeds therefrom.

                         DESCRIPTION OF THE DEBENTURES
 
     This description of the terms of the Debentures supplements and, to the
extent inconsistent therewith, modifies the description of the general terms and
provisions of the debt securities set forth in the accompanying Prospectus, to
which reference is hereby made. The following description of certain terms of
the Debentures does not purport to be complete and is qualified in its entirety
by reference to the Indenture pursuant to which the Debentures will be issued, a
copy of the proposed form of which will be filed as an exhibit to a Current
Report on Form 8-K, and to those terms made part of the Indenture by reference
to the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act").
Terms (whether or not capitalized) used but not defined herein have the meanings
given to them in the Indenture.
 
     As used below in this "Description of the Debentures" section, the
"Company" means Del Webb Corporation, but not any of its subsidiaries, unless
the context requires otherwise.
 
GENERAL
 
     The Debentures will be general unsecured senior subordinated obligations of
the Company and will be issued under an Indenture between the Company and State
Street Bank and Trust Company, as Trustee, Co-Paying Agent and Co-Registrar (the
"Trustee"), and State Street Bank and Trust Company, N.A., an affiliate of the
Trustee, as Co-Paying Agent and Co-Registrar. The Debentures will be limited to
an aggregate principal amount of $200 million and will mature on           . The
Debentures will bear interest at the rate shown on the cover page of this
Prospectus Supplement, payable on           and           of each year,
commencing on           , 1998, to holders of record (the "Holders") at the
close of business on           or           , as the case may be, immediately
preceding the respective interest payment date.
 
     The Debentures will rank pari passu with the Outstanding Debentures and the
covenants applicable to the Debentures are substantially similar to those
applicable to the Outstanding Debentures.
 
     The Debentures will be subordinated and junior in right of payment, to the
extent and in the manner set forth below, to all Senior Debt. The Company is a
holding company, which currently conducts its operations through subsidiaries.
This effectively subordinates the Debentures to all indebtedness (including
trade payables) of the Company's subsidiaries. Therefore, the Company's rights
and the rights of its creditors, including holders of Debentures, to participate
in the assets of any subsidiary upon the subsidiary's liquidation or
recapitalization will be subject to the prior claims of the subsidiary's
creditors, except to the extent that the Company may itself be a creditor with
recognized claims against the subsidiary. However, in that case the claims of
the Company would still be effectively junior to any indebtedness of the
subsidiaries to the extent the creditors are entitled to the benefit of security
interests in the assets of the subsidiary as well as to any indebtedness of the
subsidiary senior to that held by the Company. In addition, because the Company
is a holding company, it is dependent on dividends or other distributions from
its subsidiaries to make payments on its indebtedness, including the Debentures.
Such dividends or other distributions to the Company may be subject to state
law, which can restrict the ability of a corporation to pay dividends or make
other distributions to its shareholders and which protect the rights of
creditors of a corporation in the event of improperly made dividends or
distributions, as well as to present or future contractual or regulatory
restrictions that could materially restrict the subsidiaries' ability to make
such payments to the Company. The Indenture will restrict, but not prohibit, the
Company's ability to enter into contracts in the future that limit the ability
of the Company's subsidiaries to make dividends, loans or advances to it.
Payments to the Company from its subsidiaries also are contingent upon the
earnings of such subsidiaries and are subject to various business
considerations, such as the working capital needs of the subsidiaries. See "Risk
Factors -- Subordination of the Debentures."
 
     Except under limited circumstances, the Debentures will be issued in full
registered book-entry form without coupons in denominations of $1,000 and
integral multiples thereof. Beneficial owners of interests in the Global
Debentures, including the Global Debentures held by DTC or its nominees, will
not be Holders or entitled to the rights of Holders described below, which
rights may be exercised only by Holders. See "-- Book-Entry, Delivery and Form"
and "-- Certificated Debentures."
 
                                      S-15
<PAGE>   16
 
     Initially, State Street Bank and Trust Company, N.A., and the Trustee will
act as the Co-Registrars and Co-Paying Agents under the Indenture. The Company
or any of its subsidiaries may subsequently act as the Registrar or the Paying
Agent, except in certain circumstances described in the Indenture, and the
Company may change any Registrar or any Paying Agent without prior notice to the
Holders. Principal, premium and interest on any Certificated Debentures will be
payable, and Certificated Debentures may be presented for registration of
transfer or exchange, at the offices of State Street Bank and Trust Company,
N.A. in New York, New York or of the Trustee in Boston, Massachusetts. Payments
on Certificated Debentures may be paid by checks mailed to the registered
addresses of the holders of record. Holders must surrender their Certificated
Debentures to the Paying Agent to collect principal payments. The Company may
require appropriate endorsements, transfer documents and payment of a sum
sufficient to cover any transfer tax or other governmental charge payable in
connection with certain transfers or exchanges of the Debentures.
 
OPTIONAL REDEMPTION OF THE DEBENTURES
 
     The Debentures may not be redeemed by the Company prior to           .
Thereafter, the Debentures may be redeemed at the option of the Company, in
whole or in part, at the following redemption prices (expressed as a percentage
of principal amount) if redeemed during the 12-month period beginning on
  of the indicated year:

</TABLE>
 
plus, in each case, accrued and unpaid interest thereon to the redemption date.
 
     If less than all of the Debentures are to be redeemed at any time,
selection of the Debentures to be redeemed will be made by the Trustee (as to
any Certificated Debentures) or, if applicable, the Depositary from among the
outstanding Debentures on a pro rata basis, by lot or by another means that is
in compliance with the requirements of the principal national securities
exchange, if any, on which the Debentures are then listed. Notice of redemption
will be mailed at least 30 days but not more than 60 days before the redemption
date to each Holder whose Debentures are to be redeemed at the registered
address of such Holder. The Company understands that the current practice of DTC
is to determine by lot the amount of the interest of each of its direct
participants to be redeemed. On and after the redemption date, interest shall
cease to accrue on the Debentures or portions thereof called for redemption.
 
     The Debentures will not have the benefit of any sinking fund.
 
MANDATORY OFFERS TO PURCHASE THE DEBENTURES
 
     The Indenture will require the Company to make an offer to purchase all of
the outstanding Debentures upon a Change of Control and a portion of the
outstanding Debentures if the Company fails to maintain its Consolidated
Tangible Net Worth above $125 million for certain periods. See "Certain
Covenants -- Change of Control" and "-- Maintenance of Consolidated Tangible Net
Worth." The Company's ability to purchase the Debentures in the event of a
Change of Control or failure to maintain its Consolidated Tangible Net Worth may
be adversely affected by, among other things, the presence of a change of
control covenant and restriction on the acquisition by the Company of
subordinated indebtedness (which includes the Debentures) in the Credit
Facility, change of control covenants in the indentures for the Outstanding
Debentures and covenants and restrictions in the Company's credit facilities in
existence from time to time in the future. See Note 6 to the Company's
Consolidated Financial Statements, included in the Company's Annual Report on
Form 10-K for the year ended June 30, 1997, which is incorporated in the
Prospectus by reference. There can be no assurance that sufficient funds will be
available in the event of a Change of Control or failure to maintain
Consolidated Tangible Net Worth to permit the Company to make any repurchases
then required.

SUBORDINATION
 
     The Debentures will be subordinate and junior in right of payment, to the
extent and in the manner to be set forth below, to all "Senior Debt" of the
Company. The Indenture will define "Senior Debt" as all present or future "Debt"
(defined below) created, incurred, assumed or, to the extent described below,
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 Debentures; provided, however,
that Senior Debt shall not include (a) any Debt of the Company to any of its
subsidiaries, (b) any Debt of the Company or guarantees of Debt by 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, (c) the Outstanding
Debentures or (d) guarantees by the Company of Debt (i) outstanding at the date
of the Indenture or (ii) 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
(formerly The Valley National Bank of Arizona) with respect to certain
indebtedness of The Villages at Desert Hills, Inc. (which is the owner of Anthem
Phoenix and was formerly known as Del Webb Lakeview Corporation). The Debentures
will not be senior or superior in right of payment to the Outstanding Debentures
and will rank pari passu in right of payment to the Outstanding Debentures.
"Debt" will be defined in the Indenture to mean any indebtedness of a Person,
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.
 
     At March 31, 1998, the Senior Debt of the Company was $331.8 million. At
that date, on a pro forma basis after giving effect to the offering of the
Debentures and the anticipated repayment of debt with the estimated net proceeds
thereof, the Company would have had Senior Debt of $115.8 million outstanding
under the Credit Facility and the Company's short-term lines of credit and $20.8
million of other Senior Debt. Senior Debt does not include any indebtedness of
the Company's subsidiaries.
 
     By reason of this subordination, in the event of a liquidation or
dissolution of the Company or in a bankruptcy, reorganization, insolvency,
receivership or other similar proceeding relating to the Company or its
property, upon any distribution of assets, holders of Senior Debt will be
entitled to be paid principal and interest in full before principal or interest
payments may be made on the Debentures and the Holders of Debentures will be
required to pay over their share of such distribution to the holders of Senior
Debt until such Senior Debt is paid in full, except that Holders of Debentures
may receive securities that are subordinated at least to the same extent as the
Debentures are to Senior Debt. By reason of this subordination, in the event of
dissolution, insolvency or bankruptcy of the Company, Holders of the Debentures
may recover less, ratably, than holders of Senior Debt and other creditors of
the Company, or may recover nothing.
 
     The Company may not pay principal of, or interest on, the Debentures and
may not acquire any Debentures for cash or property (other than securities that
are subordinated to at least the same extent as the Debentures are subordinated
to Senior Debt) 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 or (ii) a default, other than a payment
default, on Designated Senior Debt occurs and is continuing that permits holders
of the Designated Senior Debt to accelerate its maturity and the Trustee
receives a notice of the default from a person permitted to give such notice
under the Indenture requesting that payment of principal or interest with
respect to the Debentures be prohibited. Notwithstanding the foregoing, the
Company may resume payments in respect of the Debentures upon the earlier of (a)
the date upon which the default is cured or waived or (b) in the case of a
default referred to in (ii) above, 179 days pass after notice is received (a
"Payment Blockage Period"), provided that the terms of the Indenture otherwise
permit the payment, distribution or acquisition of the Debentures at the time in
question. Only one Payment Blockage Period may be commenced within any
consecutive 365-day period with respect to the Debentures. "Designated Senior
Debt" will be defined in the Indenture to mean (i) Senior Debt of the Company
permitted to be incurred under the Indenture under any institutional credit
agreement and (ii) any other
                                      S-17

Senior Debt permitted to be incurred under the Indenture the principal amount of
which is $25 million or more.
 
CERTAIN COVENANTS
 
     AFFIRMATIVE COVENANTS.  In addition to the covenants described below, the
Indenture will require the Company, subject to certain limitations described
therein, to, among other things, do the following: (a) deliver to the Trustee
copies of all reports filed with the Commission; (b) deliver to the Trustee
quarterly officers' certificates with respect to the Company's compliance with
its obligations under the Indenture; (c) maintain its corporate existence,
subject to the provisions described below relating to mergers and acquisitions;
and (d) pay its taxes when due except where such taxes are being contested in
good faith.
 
     LIMITATIONS ON ADDITIONAL INDEBTEDNESS.  The Indenture will provide that,
after the date of the Indenture, 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 of not more than $150 million; (ii)
Indebtedness evidenced by the Debentures; (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 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). The
Indenture will not restrict any Unrestricted Subsidiary from incurring
Indebtedness, nor will Indebtedness of any Unrestricted Subsidiary 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 would be Restricted
Subsidiaries under the Indenture.
 
     LIMITATIONS ON RESTRICTED PAYMENTS.  The Indenture will provide that the
Company will not, and will not permit any of its Restricted Subsidiaries to,
directly or indirectly make any Restricted Payment after the date of the
Indenture, except as provided below in this Limitations on Restricted Payments
covenant, 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 percent of such aggregate deficit), plus (2)
     the sum of (x) 100 percent 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
                                      S-18
<PAGE>   19
 
     of the Company's and its Restricted Subsidiaries' aggregate net Investment
     in Unrestricted Subsidiaries, provided that such property so received is
     substantially similar to the property contributed to the Unrestricted
     Subsidiaries, (y) 100 percent 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 percent 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 officer's 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 percent 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 percent of the Released Asset Value since February 11, 1994, plus
     (6) 100 percent 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 the
     Limitations on Additional Indebtedness covenant.
 
     Notwithstanding the foregoing, the Indenture 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 officer's 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 Restricted Payment definition) 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;
 
          (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 the 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).
 
     LIMITATIONS ON RESTRICTIONS ON DISTRIBUTIONS FROM RESTRICTED
SUBSIDIARIES.  The Indenture will provide that the Company will 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 of the
Indenture, (c) any restrictions under any note, indenture, agreement or other
                                      S-19
<PAGE>   20
 
document evidencing any Acquired Indebtedness that was permitted to be incurred
pursuant to the 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 agreement, credit facility or similar arrangement
existing as of the date of the Indenture, 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 of the
Indenture, 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 the
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 the 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 Indebtedness 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.
 
     LIMITATIONS ON TRANSACTIONS WITH AFFILIATES.  The Indenture will provide
that the Company and each of its Restricted Subsidiaries will not, after the
date of the Indenture, 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 ten percent 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
arm's-length basis from a Person that is not an Affiliate.
 
     The Indenture will also provide that 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 disinterested
members 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 arm's-length
basis from a Person that is not an Affiliate. Delivery of a certificate as
required by the 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 arm's-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.
                                      S-20
<PAGE>   21
 
     CHANGE OF CONTROL.  Following any Change of Control, the Company shall
offer (a "Change of Control Offer") to purchase all outstanding Debentures at a
purchase price equal to 101 percent of the aggregate principal amount of the
Debentures, plus accrued and unpaid interest to the date of purchase.
 
     Within 30 days after any Change of Control, the Company, or the Trustee at
the Company's request, 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 Debentures to the Company. Any Change of Control Offer will be conducted
in compliance with applicable regulations under the federal securities laws,
including Rule 14e-l promulgated under the Securities Exchange Act of 1934, as
amended (the "Exchange Act").
 
     The Company's ability to purchase Debentures pursuant to a Change of
Control Offer may be restricted by covenants in the indentures for the
Outstanding Debentures, the Credit Facility and other credit agreements the
Company may have in the future. Also, there can be no assurance that sufficient
funds will be available at the time of any Change of Control Offer to make any
required repurchases. However, the Company's failure to comply with the Change
of Control covenant will be an Event of Default under the Indenture if such
failure continues for a specified period and the required notice is given by the
Trustee or the Holders of not less than 25 percent in principal amount of the
then outstanding Debentures.
 
     Except as described above with respect to a Change of Control, the
Indenture does not contain provisions that will afford Holders of the Debentures
protection in the event of a highly leveraged transaction, takeover,
reorganization, restructuring, recapitalization, merger or similar transaction
involving the Company that may adversely affect Holders.
 
     LIMITATIONS ON MERGERS AND CONSOLIDATIONS.  The Indenture will provide that
the Company will 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: (i) the Person formed by
or surviving such consolidation or merger (if other than the Company), or to
which such sale, lease, conveyance or other disposition shall be made
(collectively, the "Successor"), is a corporation or other legal entity
organized and existing under the laws of the United States or any State thereof
or the District of Columbia and the Successor assumes by supplemental indenture
in a form reasonably satisfactory to the Trustee all of the obligations of the
Company under the Debentures and the Indenture; (ii) immediately after giving
effect to such transaction, no Default or Event of Default shall have occurred
and be continuing; (iii) 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 (iv) 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 the
Limitations on Additional Indebtedness covenant. For this purpose, 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. The meaning of the
term "all or substantially all of the assets" has not been definitely
established, is likely to be interpreted by reference to applicable state law if
and at the time the issue arises and will be dependent on the facts and
circumstances existing at that time. Accordingly, there may be uncertainty as to
whether a Holder or beneficial owner of Debentures can determine whether a
Change of Control has occurred and exercise any remedies such Holder or
beneficial owner may have upon a Change of Control.
 
     MAINTENANCE OF CONSOLIDATED TANGIBLE NET WORTH.  The Indenture will provide
that 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
                                      S-21
<PAGE>   22
 
Worth Offer") ten percent of the principal amount of Debentures originally
issued under the Indenture (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 percent 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 officer's certificate required by the Indenture, 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 Company
shall purchase and mail or deliver payment for the Offer Amount of Debentures
tendered or, if less than the Offer Amount has been tendered, all Debentures
tendered in response to 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.
The principal amount of Debentures to be purchased pursuant to a Net Worth Offer
may be reduced by the principal amount of Debentures acquired by the Company
through purchase or redemption (other than pursuant to a Change of Control
Offer) subsequent to the Deficiency Date and surrendered to the Trustee for
cancellation. Any Net Worth Offer shall be conducted in compliance with
applicable regulations under the federal securities law, including Exchange Act
Rule 14e-l.
 
     The Company's ability to purchase Debentures in the event it is required to
make a Net Worth Offer may be adversely affected by, among other things, the
indentures for the Outstanding Debentures, the Credit Facility and other credit
agreements the Company may have in the future. There can be no assurance that
sufficient funds will be available at the time of any Net Worth Offer to make
required repurchases. The Company's failure to comply with the Maintenance of
Consolidated Tangible Net Worth covenant will be an Event of Default under the
Indenture if such failure continues for a specified period and the required
notice is given by the Trustee or the Holders of not less than 25 percent in
principal amount of the then outstanding Debentures.
 
     LIMITATION ON RANKING OF FUTURE INDEBTEDNESS.  The Company will not,
directly or indirectly, incur, create, assume, guarantee or otherwise become
liable for any indebtedness which is subordinated in right of payment to any
Senior Debt of the Company and senior in right of payment to the Debentures.
 
EVENTS OF DEFAULT
 
     An "Event of Default" will be defined in the Indenture as: (i) failure by
the Company to pay interest on any of the Debentures when it becomes due and
payable, whether or not prohibited by the subordination provisions of the
Indenture, and the continuance of any such failure for 30 days; (ii) failure by
the Company to pay the principal on the Debentures when due, either at maturity,
upon redemption at the option of the Company, by declaration of acceleration or
otherwise, whether or not prohibited by the subordination provisions of the
Indenture; (iii) failure by the Company to comply with any agreement or covenant
in the Indenture or the Debentures and continuance of such failure for 60 days
(or for ten days in the case of the covenant described under "Certain
Covenants -- Change of Control") after notice of such failure has been given to
the Company by the Trustee or by the Holders of at least 25 percent of the
aggregate principal amount of the Debentures then outstanding (except that with
respect to certain covenants, such defaults shall be Events of Default with such
notice but without such passage of time); (iv) an event of default 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, to the extent
of the Guarantee) other than Non-Recourse Indebtedness if (a) either (1) such
event of default results from the failure to pay any such Indebtedness when due
(whether at maturity or otherwise) or (2) 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 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
                                      S-22
<PAGE>   23
 
percent in principal amount of the Debentures then outstanding; (v) a final
judgment or 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, having been entered by a court or courts of competent
jurisdiction, and remaining undischarged for a period (during which execution
shall not be effectively stayed) of 60 days, against (a) the Company, (b) any of
its Material Subsidiaries which is at the time a Restricted Subsidiary or (c)
any subsidiary which is at the time a Restricted Subsidiary and which is (1) a
member of a Material Subsidiary Group and (2) material to or holds material
assets of (in each case as determined 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; and (vi) certain events of bankruptcy, insolvency or
reorganization involving (a) the Company, (b) any of its Material Subsidiaries
which is at the time a Restricted Subsidiary or (c) any subsidiary which is at
the time a Restricted Subsidiary and which is (1) a member of a Material
Subsidiary Group and (2) material to or holds material assets of (in each case
as determined 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.
 
     If an Event of Default (other than an Event of Default resulting from
bankruptcy, insolvency or reorganization involving the Company) shall have
occurred and be continuing, the Trustee by written notice to the Company, or the
Holders of at least 25 percent in aggregate principal amount of the Debentures
then outstanding by written notice to the Company and the Trustee, may declare
all amounts owing under the Debentures to be due and payable. Upon such
declaration of acceleration, the aggregate principal amount of, and all accrued
and unpaid interest on, the outstanding Debentures shall immediately become due
and payable. If an Event of Default results from bankruptcy, insolvency or
reorganization involving the Company, all outstanding Debentures shall become
due and payable without any further action or notice. The Holders of a majority
in aggregate principal amount of the Debentures then outstanding may waive or
annul an existing Default or Event of Default (other than any Default or Event
of Default in payment of principal or interest on the Debentures), and its
consequences, under the Indenture.
 
     The Holders may not institute any action to enforce the provisions of the
Indenture or the Debentures (except actions for payment of overdue principal or
interest) unless (a) such Holders previously have given the Trustee written
notice of the default and continuance thereof, (b) the Holders of not less than
25 percent in principal amount of the Debentures then outstanding have requested
the Trustee to institute such action and offered the Trustee reasonable
indemnity, (c) the Trustee has not instituted such action within 60 days of the
request and (d) the Trustee has not received direction inconsistent with such
written request from the Holders of a majority in principal amount of the
Debentures then outstanding.
 
     Subject to certain limitations, Holders of a majority in principal amount
of the Debentures then outstanding may direct the Trustee in its exercise of any
trust or power, provided that such direction does not conflict with the terms of
the Indenture and such Holders have offered to the Trustee security and
indemnity satisfactory to the Trustee. The Trustee may withhold from the Holders
notice of any continuing Default or Event of Default (except any Default or
Event of Default in payment of principal or interest on the Debentures) if the
Trustee determines that withholding such notice is in the Holders' interest.
 
     The Company is required to deliver to the Trustee quarterly a statement
regarding compliance with the Indenture, and upon any Officer of the Company
becoming aware of any Default or Event of Default, a statement specifying such
Default or Event of Default.
 
     The Indenture will provide that no director, officer, employee or
shareholder of the Company, as such, will have any liability for any obligations
of the Company under the Debentures or the Indenture. The Indenture and the
Debentures will each provide that each holder of the Debentures, and each
beneficial owner of the Debentures, by accepting the Debentures, waives and
releases all such liability.

DEFEASANCE AND DISCHARGE
 
     The Company can discharge or defease its obligations under the Indenture as
set forth below.
 
     Under terms satisfactory to the Trustee, the Company may discharge certain
obligations to Holders of Debentures that have not already been delivered to the
Trustee for cancellation and that have either become due and payable or are by
their terms due and payable within one year (or scheduled for redemption within
one year) by irrevocably depositing with the Trustee cash or United States
Government Obligations, or a combination thereof, as trust funds in an amount
certified to be sufficient to pay at maturity (or upon redemption) the principal
of and interest on such Debentures.
 
     The Company may also discharge any and all of its obligations to Holders of
the Debentures at any time ("defeasance"), but may not thereby avoid its duty to
register the transfer or exchange of the Debentures, to replace any temporary,
mutilated, destroyed, lost or stolen Debentures or to maintain an office or
agency in respect of such Debentures and certain other obligations.
Alternatively, the Company may be released with respect to the Debentures from
the obligations imposed by specified portions of Article 4 and by Article 5 of
the Indenture (which contain, among other things, the covenant described above
limiting consolidations, mergers, asset sales and leases) and omit to comply
with such Articles or portions thereof without creating an Event of Default
("covenant defeasance"). Defeasance or covenant defeasance may be effected only
if, among other things: (a) the Company irrevocably deposits with the Trustee
cash or United States Government Obligations, or a combination thereof, as trust
funds in an amount certified to be sufficient to pay at maturity the principal
of and interest on all outstanding Debentures; (b) no Event of Default under the
Indenture has occurred and is then continuing; (c) the defeasance or covenant
defeasance will not result in an event of default under any agreement to which
the Company is a party or by which it is bound; and (d) the Company delivers to
the Trustee an opinion of counsel to the effect that the Holders of Debentures
will not recognize income, gain or loss for federal income tax purposes as a
result of such defeasance or covenant defeasance and, in effect, that such
defeasance or covenant defeasance will not otherwise alter such Holders' federal
income tax treatment of principal and interest payments on the Debentures.
 
MODIFICATION OF THE INDENTURE
 
     The Indenture will provide that the Company and the Trustee may enter into
supplemental indentures without the consent of the Holders of Debentures to,
among other things: (a) cure any ambiguity or correct any inconsistency in the
Indenture; (b) make any change that does not adversely affect the legal rights
of Holders of Debentures; (c) modify, eliminate or add to the provisions of the
Indenture to the extent necessary to qualify the Indenture under applicable
federal statutes; (d) provide for uncertificated Debentures in addition to
certificated Debentures; or (e) surrender any right or power conferred by the
Indenture upon the Company.
 
     The Indenture also will contain provisions permitting the Company and the
Trustee, with the consent of the Holders of not less than a majority in
principal amount of Debentures outstanding, to add any provision to, change in
any manner or eliminate any of the provisions of the Indenture or modify in any
manner the rights of the Holders of the Debentures so affected; provided,
however, that the Company and the Trustee may not, without the consent of the

consent to an amendment, supplement or waiver with respect to the Indenture; (b)
reduce the rate of or change the time for payment of interest on any Debentures;

outstanding Debentures without the consent of each holder of Senior Debt then
outstanding that would be adversely affected in any material respect thereby.

TRANSFER AND EXCHANGE
 
     A Holder will be able to transfer or exchange Debentures only in accordance
with the provisions of the Indenture. The Registrar and the Company may require
a Holder, among other things, to furnish appropriate endorsements and transfer
documents and to pay any taxes and fees required by law or permitted by the
Indenture. The Company is not required to (i) transfer or exchange any Debenture
selected for redemption or (ii) transfer or exchange any Debenture for a period
of 15 days before a selection of Debentures to be redeemed. The registered
Holder of a Debenture (as opposed to the beneficial owner, if different) may be
treated as the owner of such Debenture for all purposes.
 
CONCERNING THE TRUSTEE
 
     The Indenture will contain certain limitations on the rights of the
Trustee, should it become a creditor of the Company, to obtain payment of claims
in certain cases or to realize on certain property received in respect of any
such claim as security or otherwise. The Trustee will be permitted to engage in
other transactions; however, if it acquires any conflicting interest, it must
eliminate such conflict or resign.
 
     The Holders of a majority in principal amount of the then outstanding
Debentures will have the right to direct the time, method and place of
conducting any proceeding for exercising any remedy available to the Trustee,
subject to certain exceptions. The Indenture provides that in case an Event of
Default occurs and is not cured, the Trustee will be required, in the exercise
of its power, to use the degree of care of a prudent person in similar
circumstances in the conduct of his, her or its own affairs. Subject to such
provisions, the Trustee will be under no obligation to exercise any of its
rights or powers under the Indenture at the request of any Holder, unless such
Holder shall have offered to the Trustee security and indemnity satisfactory to
the Trustee.

for value of such Person's Capital Stock or any other payment or distribution
made in respect thereof, either directly or indirectly, (iii) any Investment in
(a) an Unrestricted Subsidiary necessary to fund operating expenses or (b) any
other Investment in an Unrestricted Subsidiary, (iv) any principal payment,
redemption, repurchase, defeasance or other acquisition or retirement of (a)
Excluded Debt or (b) Indebtedness of the Company or its subsidiaries which is
subordinated in right of payment to the Debentures prior to the scheduled

an Excess Asset Lien; provided, however, that with respect to the Company and
its subsidiaries, Restricted Payments shall not include (a) any payment
described in clause (i) or (ii) above made to the Company or any of its Wholly
Owned Restricted Subsidiaries by any of the Company's subsidiaries, (b) any
underwritten call of Indebtedness of the Company which is convertible into
Capital Stock (other than Disqualified Stock) but only to the extent the Company
is not required to make any redemption or principal payments in respect of
Indebtedness subject to such underwritten call (other than redemption and
principal payments which are covered by the net proceeds received by the Company
from a concurrent sale of Capital Stock (other than Disqualified Stock) to the
underwriters or standby purchasers participating in such underwritten call) or
(c) the exchange by the Company of Capital Stock (other than Disqualified Stock)
for Indebtedness of the Company or a Restricted Subsidiary in an exchange offer,
but only to the extent the exchange is solely for such Capital Stock.
 
     "Restricted Subsidiaries" means each of the subsidiaries of the Company
which is not, as of the determination date, an Unrestricted Subsidiary of the
Company.
 
     "Subsidiary" of any Person means (i) any corporation of which at least a
majority of the aggregate voting power of all classes of the Common Equity is
owned by such Person directly or through one or more other subsidiaries of such
Person and (ii) any entity other than a corporation in which such Person,
directly or indirectly, owns at least a majority of the Common Equity of such
entity.
 
     "Sun City Las Vegas" means the Company's age-restricted active adult
community development located in Las Vegas, Nevada, as its geographic boundaries
existed at February 11, 1994.
 
     "Sun City Palm Desert" means the Company's age-restricted active adult
community development located in the Coachella Valley in Southern California
(formerly known as Sun City Palm Springs), as its geographic boundaries existed
at February 11, 1994.
 
     "Sun City Tucson" means the Company's age-restricted active adult community
development located in Pima County, Arizona, as its geographic boundaries
existed at February 11, 1994.
 
     "Sun City West" means the Company's age-restricted active adult community
development located in Maricopa County, Arizona, as its geographic boundaries
existed at February 11, 1994.
 
     "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.
 
     "Unrestricted Subsidiaries" means each of the subsidiaries of the Company
so designated by a resolution adopted by the Company's Board of Directors and
whose creditors have no direct or indirect recourse (including, but not limited
to, recourse with respect to the payment of principal or interest on
Indebtedness of such subsidiary) to the Company or a Restricted Subsidiary
(except to the extent the Investment made by the Company in the Unrestricted
Subsidiary is (a) permitted under the Limitations on Restricted Payments
covenant and (b) is a Guarantee); provided, however, that the Board of Directors
of the Company will be prohibited from designating any subsidiary which holds,
directly or indirectly, any of the assets of Sun City West, Sun City Tucson, Sun
City Las Vegas or Sun City Palm Desert as an Unrestricted Subsidiary. The Board
of Directors of the Company may designate an Unrestricted Subsidiary to be a
Restricted Subsidiary,
                                      S-31
<PAGE>   32
 
provided that (i) any such redesignation shall be deemed to be an incurrence by
the Company and its Restricted Subsidiaries of the Indebtedness (if any) of such
redesignated subsidiary for purposes of the Limitations on Additional
Indebtedness covenant in the Indenture as of the date of such redesignation and
(ii) immediately after giving effect to such redesignation and the incurrence of
any such additional Indebtedness, the Company and its Restricted Subsidiaries
could incur $1 of additional Indebtedness pursuant to the Consolidated Fixed
Charge Coverage Ratio in the Limitations on Additional Indebtedness covenant in
the Indenture. Subject to the foregoing, the Board of Directors of the Company
also may designate any Restricted Subsidiary to be an Unrestricted Subsidiary,
provided that (i) all previous Investments by the Company and its Restricted
Subsidiaries shall be deemed to be Restricted Payments at the time of such
designation and shall reduce the amount available for Restricted Payments under
the Limitations on Restricted Payments covenant in the Indenture and (ii)
immediately after giving effect to such designation and reduction of amounts
available for Restricted Payments under the Limitations on Restricted Payments
covenant in the Indenture, the Company and its Restricted Subsidiaries could
incur $1 of additional Indebtedness pursuant to the Consolidated Fixed Charge
Coverage Ratio in the Limitations on Additional Indebtedness described above.
Any such designation or redesignation by the Board of Directors shall be
evidenced to the Trustee by the filing with the Trustee of a certified copy of
the Resolution of the Company's Board of Directors giving effect to such
designation or redesignation and an officer's certificate certifying that such
designation or redesignation complied with the foregoing conditions and setting
forth the underlying calculations of such certificate.
 
     "Weighted Average Life to Maturity" means, when applied to any Indebtedness
or portion thereof (if applicable), at any date, the number of years obtained by
dividing (i) the then outstanding principal amount of such Indebtedness or
portion thereof (if applicable) into (ii) the sum of the products obtained by
multiplying (a) the amount of each remaining installment, sinking fund, serial
maturity or other required payment of principal, including payment at final
maturity, in respect thereof, by (b) the number of years (calculated to the
nearest one-twelfth) that will elapse between such date and the making of such
payment.
 
     "Wholly Owned Restricted Subsidiary" of the Company means a Restricted
Subsidiary of the Company of which 100 percent of the Common Equity (except for
directors' qualifying shares or certain minority interests owned by other
Persons solely due to local law requirements that there be more than one
stockholder, but which interest is not in excess of what is required for such
purpose) is owned directly by the Company or through one or more other Wholly
Owned Restricted Subsidiaries of the Company.
 
     "Wholly Owned Subsidiary" of any Person means (i) a subsidiary of which 100
percent of the Common Equity (except for directors' qualifying shares or certain
minority interests owned by other Persons solely due to local law requirements
that there be more than one stockholder, but which interest is not in excess of
what is required for such purpose) is owned directly by such Person or through
one or more other Wholly Owned Subsidiaries of such Person or (ii) any entity
other than a corporation in which such Person, directly or indirectly, owns all
of the Common Equity.
 
BOOK-ENTRY, DELIVERY AND FORM
 
     Except as set forth below, the Debentures will be issued in the form of one
or more Registered Debentures in global form (the "Global Debentures"). Each
Global Debenture will be deposited on the date of the closing of the sale of the
Debentures (the "Closing Date") with, or on behalf of DTC, as depositary (the
"Depositary"), and registered in the name of Cede & Co., as nominee of the
Depositary.
 
     DTC is a limited-purpose trust company organized under the New York Banking
Law, a "banking organization" within the meaning of the New York Banking Law, a
member of the Federal Reserve System, a "clearing corporation" within the
meaning of the New York Uniform Commercial Code and a "clearing agency"
registered pursuant to the provisions of Section 17A of the Exchange Act. DTC
holds securities that its participants ("Participants"), including Morgan
Guaranty Trust Company of New York, Brussels office, as operator of the
Euroclear system ("Euroclear"), and Cedel Bank, societe anonyme ("Cedel"),
deposit with DTC. DTC also facilitates the settlement among Participants of
securities transactions, such as transfers and pledges, in deposited securities
through electronic computerized book-entry changes in Participants' accounts,
                                      S-32
<PAGE>   33
 
thereby eliminating the need for physical movement of securities certificates.
Direct Participants include securities brokers and dealers, banks, trust
companies, clearing corporations and certain other organizations ("Direct
Participants"). DTC is owned by a number of its Direct Participants including
securities brokers and dealers, banks and trust companies that clear through or
maintain a custodial relationship with a Direct Participant, either directly or
indirectly ("Indirect Participants"). The rules applicable to DTC and its
Participants are on file with the Securities and Exchange Commission.
 
     Euroclear and Cedel hold securities for participating organizations and
facilitate the clearance and settlement of securities transactions between their
respective participants through electronic book-entry changes in accounts of
such participants. Euroclear and Cedel provide to their participants, among
other things, services for safekeeping, administration, clearance and settlement
of internationally traded securities and securities lending and borrowing.
Euroclear and Cedel interface with domestic securities markets. Euroclear and
Cedel participants are financial institutions such as underwriters, securities
brokers and dealers, banks, trust companies and certain other organizations.
Indirect access to Euroclear and Cedel is also available to others such as
banks, brokers, dealers and trust companies that clear through or maintain a
custodian relationship with a Euroclear or Cedel participant, either directly or
indirectly.
 
     Each person owning a beneficial interest must rely on the procedures of
DTC, Euroclear and Cedel and, if such person is an Indirect Participant in DTC,
on the procedures of the Participant in DTC through which such person owns its
interest, to exercise any rights and remedies of a Holder under the Indenture.
 
     The Company expects that pursuant to procedures established by the
Depositary (i) upon deposit of the Global Debentures, the Depositary will credit
the accounts of participants designated by the Underwriters with an interest in
the applicable Global Debentures and (ii) ownership of the Debentures evidenced
by the Global Debentures will be shown on, and transfer of ownership thereof
will be effected only through, records maintained by the Depositary (with
respect to the interests of Participants), the Participants and the Indirect
Participants. Transfers between participants in Euroclear and Cedel will be
effected in the ordinary way in accordance with their respective rules and
operating procedures. The laws of some states require that certain persons take
physical delivery in definitive form of securities that they own and that
security interests in negotiable instruments can only be perfected by delivery
of certificates representing the instruments. Consequently, the ability to
transfer Debentures evidenced by the Global Debentures will be limited to such
extent.
 
     So long as the Depositary or its nominee is the registered owner of a
Debenture, the Depositary or such nominee, as the case may be, will be
considered the sole owner or holder of the Debentures represented by the Global
Debentures for all purposes under the Indenture. Except as provided below,
owners of beneficial interests in a Global Debenture will not be entitled to
have Debentures represented by such Global Debenture registered in their names,
will not receive or be entitled to receive physical delivery of Debentures in
certificated form ("Certificated Debentures"), and will not be considered the
owners or holders thereof under the Indenture for any purpose, including with
respect to the giving of any directions, instructions or approvals to the
Trustee thereunder. As a result, the ability of a person having beneficial
interest in Debentures represented by a Global Debenture to pledge such interest
to persons or entities that do not participate in the Depositary's system, or to
otherwise take actions with respect to such interest, may be affected by the
lack of a physical certificate evidencing such interest.
 
     Neither the Depositary nor Cede & Co. will consent or vote with respect to
the Debentures. The Company understands that under its usual procedures, DTC
mails an omnibus proxy (an "Omnibus Proxy") to its Participants as soon as
possible after the applicable record date. The Omnibus Proxy assigns Cede &
Co.'s and Euroclear and Cedel's consenting or voting rights to those Direct
Participants to whose accounts the Debentures are credited on the applicable
record date (to be identified in a listing attached to the Omnibus Proxy).
 
     Neither the Company nor the Trustee will have any responsibility or
liability for any aspect of the records relating to or payments made on account
of Debentures by the Depositary, or for maintaining, supervising or reviewing
any records of the Depositary relating to such Debentures.
 
                                      S-33
<PAGE>   34
 
     Payments with respect to the principal of, premium, if any, and interest
on, any Debenture represented by a Global Debenture registered in the name of
the Depositary or its nominee on the applicable record date will be payable by
the Trustee to, or at the direction of, the Depositary or its nominee in its
capacity as the registered holder of the Global Debenture representing such
Debentures under the Indenture. The Company understands that the Depositary's
practice is to credit Direct Participants' accounts on the relevant payment date
in accordance with their respective holdings shown on the Depositary's records
unless the Depositary has reason to believe that it will not receive payment on
such payment date. Payments by Participants to beneficial owners will be
governed by standing instructions and customary practices, as is the case with
securities for the accounts of customers in bearer form or registered in
"street-name," and will be the responsibility of such Participant and not of the
Depositary or the Company, subject to any statutory or regulatory requirements
as may be in effect from time to time. Payment of principal, premium, if any,
and interest to the Depositary is the responsibility of the Company or the
Trustee. Disbursement of such payments to Direct Participants is the
responsibility of the Depositary, and disbursement of such payments to the
beneficial owners is the responsibility of Direct and Indirect Participants.
Distribution with respect to ownership of interests held through Euroclear or
Cedel will be credited to the cash accounts of Euroclear participants or Cedel
participants in accordance with the relevant system's rules and procedures, to
the extent received by the Depositary.
 
     Under the terms of the Indenture, the Company and the Trustee may treat the
persons in whose names the Debentures, including the Global Debentures, are
registered as the owners thereof for the purpose of receiving such payments and
for any and all other purposes whatsoever. Consequently, neither the Company nor
the Trustee has or will have any responsibility or liability for the payment of
such amounts to beneficial owners of Debentures (including principal, premium,
if any, or interest), or to immediately credit the accounts of the relevant
Participants with such payment, in amounts proportionate to their respective
holdings in principal amount of beneficial interests in the Global Debenture as
shown on the records of the Depositary. Payments by the Participants and the
Indirect Participants to the beneficial owners of Debentures will be governed by
standing instructions and customary practice and will be the responsibility of
the Participants or the Indirect Participants.
 
SAME-DAY FUNDS SETTLEMENT AND PAYMENT
 
     Settlement for the Debentures will be made by the Underwriters in
immediately available funds. Payments in respect of the Debentures represented
by the Global Debentures (including principal, premium, if any, and interest)
will be made in immediately available funds to the accounts specified by the
Depositary. With respect to Debentures represented by Certificated Debentures, a
Paying Agent (initially, the Trustee and State Street Bank and Trust Company,
N.A.) will make all payments of principal, premium, if any, and interest, by
mailing a check to the registered address of each holder of such Debentures. The
Debentures will trade in the Depositary's Same-Day Funds Settlement System until
maturity, or until the Debentures are issued in certificated form, and secondary
market trading activity in the Debentures (other than through Euroclear and
Cedel) will therefore be required by the Depositary to settle in immediately
available funds. No assurance can be given as to the effect, if any, of
settlement in immediately available funds on trading activity in the Debentures.
 
     Investors electing to own their interests through Euroclear or Cedel
accounts will follow the settlement procedures applicable to conventional
eurobonds in registered form. Interests will be credited to the securities
custody accounts of Euroclear and Cedel holders on the business day following
the settlement date against payment for value on the settlement date.
 
     The information above concerning the Depositary, Euroclear and Cedel and
the Depositary's, Euroclear's and Cedel's book-entry systems has been obtained
from sources that the Company believes to be reliable. The Company will have no
responsibility for the performance by the Depositary, its Participants or its
Indirect Participants, or Euroclear, Cedel and their participants, of their
respective obligations as described herein or under the rules and procedures
governing their respective operations.

CERTIFICATED DEBENTURES
 
     If (i) the Company notifies the Trustee in writing that the Depositary is
no longer willing or able to act as a depositary and the Company is unable to
locate a qualified successor within 90 days, (ii) the Company, at its option,
notifies the Trustee in writing that it elects to cause the issuance of
Debentures in certificated form under the Indenture or (iii) if an Event of
Default has occurred and is continuing, then, upon surrender by the Depositary
of the applicable Global Debentures, Certificated Debentures will be issued to
each person that the Depositary identifies as the beneficial owner of the
Debentures represented by such Global Debentures. In addition, subject to
certain conditions, any person having a beneficial interest in a Global
Debenture may, upon request to the Trustee, exchange such beneficial interest
for Debentures in the form of Certificated Debentures. Upon any such issuance,
the Trustee is required to register such Certificated Debentures in the name of
such person or persons (or the nominee of any thereof), and cause the same to be
delivered thereto.
 
     Neither the Company nor the Trustee shall be liable for any delay by the
Depositary or any Participant or Indirect Participant in identifying the
beneficial owners of Debentures, and the Company and the Trustee may
conclusively rely on, and shall be protected in relying on, instructions from
the Depositary for all purposes (including with respect to the registration and
delivery, and the respective principal amounts, of the Debentures to be issued).

                          CERTAIN FEDERAL TAX MATTERS
 
     The following is a general discussion of certain United States federal tax
consequences of the acquisition, ownership and disposition of a Debenture by an
initial purchaser of Debentures that, for United States federal income tax
purposes, is not a "United States person" (a "Non-U.S. Holder"). For purposes of
this discussion, a "United States person" means a citizen or resident of the
United States, a corporation, partnership or other entity created or organized
in the United States or under the laws of the United States or of any political
subdivision thereof, or an estate or trust whose income is includible in gross
income for United States federal income tax purposes regardless of its source.
This discussion does not consider any specific facts or circumstances that may
apply to a particular Non-U.S. Holder and does not deal with special situations,
such as those of dealers in securities or currencies, financial institutions,
life insurance companies or persons holding Debentures as a part of a hedging,
straddle or synthetic security transaction. The discussion below is based upon
the provisions of the Internal Revenue Code of 1986, as amended (the "Code"),
and Regulations, rulings and judicial decisions published thereunder as of the
date hereof, which authorities may be repealed, revoked or modified, possibly on
a retroactive basis, so as to result in United States federal tax consequences
different from those discussed below. ALL PERSONS CONSIDERING THE PURCHASE,
OWNERSHIP OR DISPOSITION OF DEBENTURES SHOULD CONSULT THEIR TAX ADVISORS
CONCERNING THE UNITED STATES FEDERAL TAX CONSEQUENCES IN LIGHT OF THEIR
PARTICULAR SITUATIONS AS WELL AS ANY CONSEQUENCES ARISING UNDER THE LAWS OF ANY
OTHER TAXING JURISDICTION.
 
PAYMENTS OF INTEREST
 
     A Non-U.S. Holder will not be subject to United States federal income or
withholding tax on payments of principal or interest on a Debenture, unless such
Non-U.S. Holder is a direct or indirect ten percent or greater shareholder of
the Company, a controlled foreign corporation related to the Company or a bank
receiving interest described in section 881(c)(3)(a) of the Code. To qualify for
the exemption from taxation, the last United States payor in the chain of
payment prior to payment to a Non-U.S. Holder (the "Withholding Agent") must
have received in the year in which a payment of interest or principal occurs, or
in either of the two preceding calendar years, a statement that (a) is signed by
the beneficial owner of the Debenture under penalties of perjury, (b) certifies
that such owner is a Non-U.S. Holder and (c) provides the name and address of
the beneficial owner. The statement may be made on an Internal Revenue Service
Form W-8 or a substantially similar form, and the beneficial owner must inform
the Withholding Agent of any change in the information on the statement within
30 days of such change. If the Debenture is held through a securities clearing
organization or certain other financial institutions, the organization or
institution may provide a signed statement to the Withholding Agent. However, in
such case, the signed statement must be accompanied by a copy of the IRS Form
W-8 or the substitute form provided by the beneficial owner to the organization
or institution. Recently adopted Treasury Regulations would require the
production of certain documentary evidence to support the claim for exemption by
a Non-U.S. Holder with respect to payments made after December 31, 1999.
 
     If payments of interest to a non-U.S. Holder are effectively connected with
the conduct by such Holder of a trade or business in the United States, such
payments will be subject to United States federal income tax on a net basis at
the rates applicable to United States persons generally (and, with respect to
corporate Holders, may also be subject to a 30 percent branch profits tax).
Payments that are subject to United States federal income tax on a net basis
will not be subject to United States federal withholding tax so long as the
Holder provides the Company or a Paying Agent with a properly executed Internal
Revenue Service Form 4224.
 
SALE, EXCHANGE OR REDEMPTION OF DEBENTURES
 
     Generally, a Non-U.S. Holder will not be subject to United States federal
income or withholding tax on any amount which constitutes capital gain upon
retirement or disposition of a Debenture, unless (a) such Holder is an
individual who is present in the United States for 183 days or more in the
taxable year of disposition and either (i) such individual has a "tax home" (as
defined in Section 911(d)(3) of the Code) in the United States (unless such gain
is attributable to a fixed place of business in a foreign country maintained
                                      S-36
<PAGE>   37
 
by such individual and has been subject to foreign tax of at least ten percent)
or (ii) the gain is attributable to an office or other fixed place of business
maintained by such individual in the United States or (b) the gain is
effectively connected with the conduct of a trade or business in the United
States by the Non-U.S. Holder.
 
     If a Non-U.S. Holder of a Debenture is engaged in a trade or business in
the United States and if interest on the Debenture is effectively connected with
the conduct of such trade or business, the Non-U.S. Holder will generally be
subject to regular United States federal income tax on any gain realized on the
sale, exchange or other disposition of the Debenture in the same manner and at
the rates applicable to United States persons generally (and, with respect to
corporate Holders, may also be subject to a 30 percent branch profits tax). Such
a Holder will be required to provide to the Company or a Paying Agent a properly
executed IRS Form 4224 in order to claim an exemption from withholding tax.
 
FEDERAL ESTATE TAX
 
     Subject to applicable estate tax treaty provisions, Debentures will not be
includable in the estate of a Non-U.S. Holder unless the individual is a direct
or indirect ten percent or greater shareholder of the Company or, at the time of
such individual's death, payments in respect of the Debentures would have been
effectively connected with the conduct by such individual of a trade or business
in the United States.
 
INFORMATION REPORTING AND BACKUP WITHHOLDING
 
     No information reporting or backup withholding will be required with
respect to payments made by the Company or any paying agent to Non-U.S. Holders
if the statement described under "Payments of Interest" has been received and
the payor does not have actual knowledge that the beneficial owner is a United
States person. However, interest paid to a Non-U.S. Holder will be required to
be reported annually on IRS Form 1042-S. If any payments of principal and
interest are made to the beneficial owner by or through the foreign office of a
foreign custodian, foreign nominee or the foreign agent of such beneficial
owner, or if the foreign office of a foreign "broker" (as defined in applicable
Treasury Regulations) pays the proceeds of the sale of a Debenture to the seller
thereof, backup withholding information reporting will not apply. Information
reporting requirements (but not backup withholding) will apply, however, to a
payment by a foreign office of a broker that is a United States person, that
derives 50 percent or more of its gross income for certain periods from the
conduct of a trade or business in the United States or that is a "controlled
foreign corporation" (generally, a foreign corporation controlled by certain
United States shareholders) with respect to the United States unless the broker
has documentary evidence in its records that the holder is a Non-U.S. Holder and
certain other conditions are met or the Holder otherwise establishes an
exemption. Payment by a United States office of a broker is subject to both
backup withholding at a rate of 31 percent and information reporting unless the
holder certifies under penalties of perjury that it is a Non-U.S. Holder or
otherwise establishes an exemption.
 
     Backup withholding is not an additional tax. Any amounts withheld under the
backup withholding rules will be refunded or credited against the Non-U.S.
Holder's United States federal income tax liability, provided that the required
information is furnished to the Internal Revenue Service.
 
     On October 7, 1997, the Treasury Department issued final Treasury
Regulations (and subsequently released guidance regarding the effective date of
such Treasury Regulations) governing information reporting and the certification
procedures regarding withholding and backup withholding on certain amounts paid
to non-United States persons after December 31, 1999. Such Regulations, among
other things, may change the certification procedures relating to the receipt by
intermediaries of payments on behalf of a beneficial owner of a Debenture.
Prospective investors should consult their tax advisors regarding the effect, if
any, of such new Treasury Regulations on an investment in the Debentures.
 
     THE FOREGOING IS INTENDED ONLY AS A SUMMARY OF CERTAIN UNITED STATES
FEDERAL INCOME TAX ASPECTS RELEVANT TO NON-U.S. HOLDERS AND IS NOT A SUBSTITUTE
FOR CAREFUL TAX PLANNING AND ADVICE BASED UPON THE INDIVIDUAL CIRCUMSTANCES OF
THE HOLDER.

</TABLE>
 
     Under the terms and conditions of the Underwriting Agreement, the
Underwriters have agreed to take and pay for all of the Debentures, if any are
taken.
 
     The Underwriters severally propose to offer the Debentures directly to the
public at the price to the public set forth on the cover page hereof, or at such
price less a concession not in excess of   % of the principal amount of the
Debentures on sales to certain dealers. The Underwriters may allow, and such
dealers may reallow, a concession of not in excess of   % of the principal
amount of the Debentures on sales to certain other dealers. The offering of the
Debentures is made for delivery when, as and if accepted by the Underwriters and
is subject to prior sale and to withdrawal, cancellation or modification of the
offer without notice. The Underwriters reserve the right to reject any order for
the purchase of Debentures. After the public offering, the offering price and
concession may be changed by the Underwriters.
 
     The Company has agreed to indemnify the Underwriters against certain
liabilities, including liabilities under the Securities Act of 1933, or to
contribute to payments that the Underwriters may be required to make in respect
thereof.
 
     SBC Warburg Dillon Read Inc. has from time to time performed, and may in
the future from time to time perform, investment banking services for the
Company. SBC Warburg Dillon Read Inc. and Goldman, Sachs & Co. have from time to
time acted, and may in the future from time to time act, as underwriters for the

                                  THE COMPANY
 
     Del Webb Corporation develops residential communities ranging from
smaller-scale, non-amenitized communities within its conventional homebuilding
operations to large-scale, master-planned communities with extensive amenities.
The Company currently conducts its operations in the states of Arizona, Nevada,
California, Texas and South Carolina.
 
     The Company's primary activities involve the development of large-scale,
master-planned communities with extensive amenities for active adults age 55 and
over. The Company is one of the nation's leading developers of such
age-qualified active adult communities. It has extensive experience in the
active adult community business, having built and sold more than 56,000 homes at
ten Sun City communities over the past 37 years. The Company designs, develops
and markets these communities, controlling all phases of the master plan
development process from land selection through the construction and sale of
homes. Within its communities, the Company is usually the exclusive developer of
homes.
 
     The Company was incorporated in 1946 in Arizona and reincorporated in 1994
in Delaware. The Company's principal executive offices are located at 6001 North
24th Street, Phoenix, Arizona 85016 and its telephone number is (602) 808-8000.
The Company conducts substantially all of its activities through subsidiaries
and, as used in this Prospectus and the accompanying Prospectus Supplement, the
term the "Company" includes Del Webb Corporation and its subsidiaries unless the
context indicates otherwise.
 
                                USE OF PROCEEDS
 
     Unless otherwise set forth in the accompanying Prospectus Supplement, the
net proceeds from the sale of the Securities will be used to reduce outstanding
balances under the Company's revolving credit facility, to fund land
acquisitions and development of new projects and for general corporate purposes.
Amounts so repaid under the revolving credit facility may be reborrowed in the
future.
 
                CONSOLIDATED RATIO OF EARNINGS TO FIXED CHARGES

(1) Earnings were inadequate to cover fixed charges by $21.6 million due to a
    $65.0 million non-cash loss from impairment of southern California real
    estate inventories incurred in connection with the Company's adoption of
    Statement of Financial Accounting Standards No. 121, Accounting for the
    Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of.
    See Note 12 to the Company's Consolidated Financial Statements included in
    its annual report on Form 10-K for the fiscal year ended June 30, 1996.
 
     The ratio of earnings to fixed charges is calculated by dividing earnings
by fixed charges. For this purpose "earnings" means earnings (loss) from
continuing operations before income taxes plus (a) fixed charges and interest
amortized to cost of sales minus (b) capitalized interest. "Fixed charges" means
total interest, whether capitalized or expensed (including the portion of rent
expense representative of interest costs), plus (i) debt-related fees and (ii)
amortization of deferred financing costs.
 
                         DESCRIPTION OF DEBT SECURITIES
 
     The Debt Securities will constitute senior, senior subordinated or
subordinated (including, if applicable, junior subordinated) debt of the Company
and will be issued under a Senior Debt Indenture (the "Senior Debt Indenture"),
a Senior Subordinated Debt Indenture (the "Senior Subordinated Debt Indenture")
or a
 
                                        3
<PAGE>   43
 
Subordinated Debt Securities Indenture (the "Subordinated Debt Indenture"), in
each case between the Company and a Trustee (the "Trustee"). The Senior Debt
Indenture, Senior Subordinated Debt Indenture and the Subordinated Debt
Indenture are sometimes referred to below individually as an "Indenture" and
collectively as the "Indentures." Unless otherwise stated in the Prospectus
Supplement, the Trustee under the first Indenture under which Debt Securities
will be issued will be State Street Bank and Trust Company. State Street Bank
and Trust Company is also the trustee under the indenture for the Company's $150
million of 9 3/4% Senior Subordinated Debentures due 2008 and, unless otherwise
stated in the applicable Prospectus Supplement, may also be the Trustee under
more than one of the other Indentures. (See "Concerning the Trustee.") The Debt
Securities offered by this Prospectus and the accompanying Prospectus Supplement
are referred to below as the "Offered Debt Securities." If and to the extent set
forth in the accompanying Prospectus Supplement, the Offered Debt Securities
will be convertible into Preferred or Common Stock of the Company or issued as
part of Units of Offered Debt Securities and other Securities. If the Offered
Debt Securities are to be issued as part of Units of Debt Securities and other
Securities or may be issued in exchange for Preferred Stock, the Prospectus
Supplement will describe any applicable material federal income tax
consequences.
 
     The following summaries of certain provisions of the Indentures and the
Debt Securities do not purport to be complete. Except to the extent set forth in
the Prospectus Supplement with respect to a particular issue of Debt Securities,
the Indentures are substantially identical, except for the provisions relating
to subordination, including the fact that senior subordinated Debt Securities
will rank senior to the subordinated Debt Securities.
 
GENERAL
 
     The Indenture for the Offered Debt Securities will not limit the amount of
additional indebtedness the Company or any of its subsidiaries may incur, except
as may be provided in the accompanying Prospectus Supplement. The Debt
Securities will be unsecured senior, senior subordinated or subordinated
obligations of the Company, as set forth in the accompanying Prospectus
Supplement.
 
     The Company is a holding company, which currently conducts its operations
through subsidiaries. In addition to the subordination described under
"Subordination of Senior Subordinated and Subordinated Debt Securities" below
and as may be described in the accompanying Prospectus Supplement, this
effectively subordinates the Debt Securities to all indebtedness (including
trade payables) of the Company's subsidiaries. Therefore, the Company's rights
and the rights of its creditors, including holders of Debt Securities, to
participate in the assets of any subsidiary upon the latter's liquidation or
recapitalization will be subject to the prior claims of the subsidiary's
creditors (including third persons who have the benefit of guarantees given by
the subsidiary), except to the extent the Company may itself be a creditor with
recognized claims against the subsidiary. However, in that case the claims of
the Company would still be effectively junior to any indebtedness of the
subsidiary to the extent the holders of that indebtedness are entitled to the
benefit of security interests in the assets of the subsidiary, as well as to any
indebtedness of that subsidiary which is senior to any debt or other claims held
by the Company. In addition, amounts which may from time to time be outstanding
under the Company's $400 million principal debt facility are guaranteed by
subsidiaries of the Company that hold substantially all of its consolidated
assets. The Debt Securities, including any senior Debt Securities, will not be
so guaranteed. As a result, the holders of that debt outstanding under the
Company's principal debt facility will have a claim against the assets of the
Company's subsidiaries before those assets are available to make payments due on
the Debt Securities.
 
     Also, because the Company is a holding company, it is dependent on
dividends or other distributions from its subsidiaries to make payments on its
indebtedness, including the Debt Securities. Such dividends or other
distributions to the Company may be subject to state law, which can restrict the
ability of a corporation to pay dividends or make other distributions to its
shareholders and which protect the rights of creditors of a corporation,
including third persons who have the benefit of guarantees given by the
corporation, in the event of improperly made dividends or distributions, as well
as to present or future contractual or regulatory restrictions that could
materially restrict the ability of the subsidiaries to make such payments to the
Company. The accompanying Prospectus Supplement discloses, to the extent
material to the Company, any
                                        4
<PAGE>   44
 
contractual restrictions on the ability of the subsidiaries of the Company to
make dividends, loans or advances to the Company that exist at the date of that
Prospectus Supplement. Except as may be described in the accompanying Prospectus
Supplement, the Indenture for the Offered Debt Securities will not restrict the
Company's ability to enter into contracts in the future that limit the ability
of the Company's subsidiaries to make dividends, loans or advances to it.
Payments to the Company from its subsidiaries also are contingent upon the
earnings of such subsidiaries and are subject to various business
considerations, such as the working capital needs of the subsidiaries.
 
     Reference is made to the accompanying Prospectus Supplement for the
following terms of and information relating to the Offered Debt Securities (to
the extent such terms are applicable to such Debt Securities): (a) the specific
designation, aggregate principal amount, purchase price and denomination; (b)
the date of maturity; (c) the interest rate or rates (or the method by which
such rate will be determined), if any; (d) the date from which interest will
accrue and dates on which any such interest will be payable; (e) the rights of
the Company to defer interest, if any; (f) the place or places where the
principal of, premium, if any, and interest, if any, on the Offered Debt
Securities will be payable; (g) whether the Offered Debt Securities are senior,
senior subordinated or subordinated (including junior subordinated) Debt
Securities; (h) any redemption, repayment or sinking fund provisions; (i) any
obligation of the Company to offer to purchase the Offered Debt Securities in
the event of a Change of Control (as defined) of the Company; (j) whether the
Offered Debt Securities are convertible into Preferred Stock or Common Stock and
the terms of the security into which they are convertible (see "Description of
Capital Stock"), the conversion price, other terms related to conversion and any
anti-dilution protections; (k) whether the Offered Debt Securities will be sold
as part of Units consisting of Offered Debt Securities and other Securities; (l)
any applicable material federal income tax consequences; and (m) any other
material specific terms of the Offered Debt Securities, including any material
additional events of default or covenants provided for with respect to the
Offered Debt Securities and any material terms that may be required by or
advisable under applicable laws or regulations.
 
     Debt Securities will bear interest at a fixed rate or a floating rate. Debt
Securities bearing no interest or interest at a rate that at the time of
issuance is below the prevailing market rate or as part of Units consisting of
Debt Securities and other Securities may be sold or deemed to be sold at a
discount below their stated principal amount. With respect to any Debt
Securities as to which the Company has the right to defer interest, the holders
of such Debt Securities may be allocated interest income for federal and state
income tax purposes without receiving equivalent, or any, interest payments. Any
material federal income tax considerations applicable to any such discounted
Debt Securities or to certain Debt Securities issued at par that are treated as
having been issued at a discount for federal income tax purposes will be
described in the Prospectus Supplement.
 
GLOBAL DEBT SECURITIES
 
     If any Debt Securities are represented by one or more Global Securities,
the applicable Prospectus Supplement will describe the terms of the depositary
arrangement with respect to such Global Securities.
 
SUBORDINATION OF SENIOR SUBORDINATED AND SUBORDINATED DEBT SECURITIES
 
     The senior subordinated and subordinated Debt Securities will be
subordinate and junior in right of payment, to the extent and in the manner to
be set forth in the Indenture, to all "Senior Debt" of the Company. Except to
the extent set forth in the accompanying Prospectus Supplement, the Indenture
for the Offered Debt Securities that are senior subordinated or subordinated
Debt Securities will define "Senior Debt" as all present or future
"Indebtedness" (defined below) created, incurred, assumed or, to the extent
described below, guaranteed by the Company (and all renewals, extensions or
refundings thereof), unless the instrument under which such Indebtedness is
created, incurred, assumed or guaranteed provides that such Indebtedness is not
senior or superior in right of payment to the Offered Debt Securities in
question; provided, however, that Senior Debt shall not include (a) any
Indebtedness of the Company to any of its subsidiaries, (b) any trade payables
of the Company or (c) except to the extent set forth or referred to in the
 
                                        5
<PAGE>   45
 
accompanying Prospectus Supplement, guarantees by the Company of Indebtedness
outstanding at the date hereof or that may be outstanding in the future.
 
     Each Senior Subordinated Debt Indenture will provide that the Company will
not issue any Indebtedness that is subordinated in right of payment to any
Senior Debt of the Company and is senior in right of payment to the Debt
Securities covered by the Senior Subordinated Debt Indenture. No Subordinated
Debt Indenture will contain a similar provision. Except as may otherwise be
provided in the accompanying Prospectus Supplement, "Indebtedness" will be
defined in the Indenture for the Offered Debt Securities to mean any
indebtedness of a person, contingent or otherwise, 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), evidenced by bonds, notes, debentures or
similar instruments or letters of credit or representing the balance deferred
and unpaid of the purchase price of any property or interest therein (except any
such balance that constitutes a trade payable), all capitalized lease
obligations and all direct or indirect obligations that arise as a result of
claims under or drawings pursuant to surety, performance, completion or
maintenance bonds.
 
     By reason of such subordination, in the event of dissolution, insolvency,
bankruptcy or other similar proceedings, upon any distribution of assets: (a)
holders of Senior Debt will be entitled to be paid in full before payments may
be made on senior subordinated and subordinated Debt Securities and the holders
of senior subordinated and subordinated Debt Securities will be required to pay
over their share of such distributions to the holders of Senior Debt until such
Senior Debt is paid in full (except to the extent, if at all, that holders of
senior subordinated and subordinated Debt Securities may receive securities that
are subordinated to the same extent the senior subordinated and subordinated
Debt Securities are subordinated to Senior Debt); (b) in addition, holders of
senior subordinated debt will be entitled to be paid in full before payments may
be made on subordinated Debt Securities and holders of subordinated Debt
Securities will be required to pay over their share of such distributions to the
holders of senior subordinated debt until such senior subordinated debt is paid
in full (except to the extent, if at all, that holders of subordinated Debt
Securities may receive securities that are subordinated to the same extent the
subordinated Debt Securities are subordinated to senior subordinated debt); and
(c) creditors of the Company who are not holders of senior subordinated or
subordinated Debt Securities may recover less, ratably, than holders of Senior
Debt and may recover more, ratably, than the holders of the senior subordinated
or subordinated Debt Securities, and creditors of the Company who are not
holders of subordinated Debt Securities may recover less, ratably, than holders
of Senior Debt and may recover more, ratably, than holders of subordinated Debt
Securities. Accordingly, such subordination may result in a reduction or
elimination of payments to the holders of all senior subordinated and
subordinated Debt Securities or all subordinated Debt Securities.
 
     Except as may otherwise be described in the accompanying Prospectus
Supplement, no payment of principal or interest with respect to any of the
Offered Debt Securities that are senior subordinated or subordinated Debt
Securities may be made, nor may the Company acquire any Offered Debt Securities
that are senior subordinated or subordinated Debt Securities, in each case
except as set forth in the Indenture for such Offered Debt Securities, if any
default with respect to Senior Debt that permits the acceleration of the
maturity of any Senior Debt occurs and is continuing and such default is either
the subject of judicial proceedings or the Company receives notice (a "Default
Notice") of the default from a holder of Senior Debt entitled to give such a
notice. By reason of these provisions, in the event of a default on any Senior
Debt of the Company that is presently existing or may be incurred in the future,
payments of principal of and interest and premium, if any, on the Offered Debt
Securities that are senior subordinated or subordinated Debt Securities may not
be permitted until such Senior Debt is paid in full. However, except as may
otherwise be described in the accompanying Prospectus Supplement, the Company
may resume payments in respect of the Offered Debt Securities that are senior
subordinated or subordinated Debt Securities and may acquire such senior
subordinated or subordinated Debt Securities if (a) 179 days pass after the
Default Notice is given, if the default with respect to such Senior Debt is not
then the subject of judicial proceedings, or (b) the default with respect to
such Senior Debt is cured or waived and, in each case described in the foregoing
clauses (a) and (b), the terms of the Indenture otherwise permit the payment or
acquisition of such Offered Debt Securities at the time in question. The
Company's principal credit facility restricts the acquisition by the Company of
its subordinated indebtedness, including any senior subordinated or subordinated
Debt Securities, prior to the
 
                                        6
<PAGE>   46
 
term of the principal credit facility as it may be extended from time to time,
and the Indentures for the Company's $100 million of 9 3/4% Senior Subordinated
Debentures, $100 million of 9% Senior Subordinated Debentures and $150 million
of 9 3/4% Senior Subordinated Debentures due 2008 restrict the acquisition,
prior to March 1, 2003, February 15, 2006 and January 15, 2008, respectively, of
subordinated Debt Securities issued pursuant to the Subordinated Debt Indenture.
The Prospectus Supplement or the information incorporated herein by reference
sets forth the approximate amount of Senior Debt and Senior Subordinated Debt
outstanding as of the end of the most recent fiscal quarter of the Company.
 
CERTAIN COVENANTS OF THE COMPANY
 
     AFFIRMATIVE COVENANTS.  In addition to such other covenants, if any, as may
be described in the accompanying Prospectus Supplement and except as may
otherwise be set forth therein, the Indenture for the Offered Debt Securities
will require the Company, subject to certain limitations described therein, to,
among other things, do the following: (a) deliver to the Trustee copies of all
reports filed with the Commission; (b) deliver to the Trustee annual officers'
certificates with respect to the Company's compliance with its obligations under
that Indenture; (c) maintain its corporate existence subject to the provisions
described below relating to mergers and consolidations; and (d) pay its taxes
when due except where such taxes are being contested in good faith. Except as
may be set forth in the accompanying Prospectus Supplement, the Indentures will
not restrict the business or operations of the Company or its subsidiaries,
limit their indebtedness or prohibit any liens, charges or other encumbrances on
any properties or other assets they may have from time to time.
 
     DIVIDENDS AND OTHER PAYMENTS.  Except as may otherwise be provided in the
accompanying Prospectus Supplement and except as may otherwise be set forth in
the Indenture for the Offered Debt Securities, that Indenture will generally
prohibit the Company from making a "Restricted Payment" (defined below) if, at
the time of the Restricted Payment, (a) an Event of Default (as defined) has
occurred under the Indenture and is continuing or would occur as a consequence
of the Restricted Payment or (b) if, upon giving effect to the Restricted
Payment, the aggregate amount expended for all Restricted Payments exceeds the
sum of (i) a specified percentage of the aggregate consolidated net earnings of
the Company accrued during certain fiscal quarters, (ii) the aggregate net
proceeds received by the Company from the issuance or sale of capital stock of
the Company, (iii) the amount expended by the Company for the purchase,
redemption or other acquisition or retirement for value of any preferred stock
of the Company plus (iv) the amount set forth in the accompanying Prospectus
Supplement. Except as may be otherwise provided in the accompanying Prospectus
Supplement, a "Restricted Payment" will be defined as any of the following: (1)
declaring or paying any dividend on, or making any distribution to the holders
of, any shares of the Company's capital stock, other than dividends or
distributions payable in "Equity Interests" (defined as equity securities or
securities with a right to acquire equity securities (other than convertible
debt securities) of the Company) or (2) purchasing, redeeming or otherwise
acquiring or retiring for value any Equity Interests.
 
     CHANGE OF CONTROL.  Except as may otherwise be set forth in the
accompanying Prospectus Supplement, the Indenture for the Offered Debt
Securities will provide that, if a Change of Control occurs, the Company will be
obligated to offer to purchase all outstanding Offered Debt Securities at a
purchase price equal to 100 percent of the aggregate principal amount of the
Debt Securities, plus accrued and unpaid interest to the date of purchase. Any
offer to purchase Offered Debt Securities upon a Change of Control will be
conducted in compliance with applicable regulations under the federal securities
laws, including Exchange Act Rule 14e-1. Any limitations on the Company's
financial ability to purchase Offered Debt Securities upon a Change of Control
will be described in the accompanying Prospectus Supplement. Except as may be
otherwise provided in the accompanying Prospectus Supplement, a "Change of
Control" will be defined in the Indenture for the Offered Debt Securities as any
of the following: (a) all or substantially all of the Company's assets are sold
as an entirety to any person or it engages in any merger, consolidation, sale of
capital stock, sale of beneficial ownership interests or any other transactions
as a result of which its shareholders immediately prior to such transactions
own, directly or indirectly, in the aggregate less than 50 percent of the total
voting power entitled to vote in the election of (i) its directors, if it is the
surviving entity, or (ii) the directors, managers or trustees of (1) the
surviving entity or (2) the purchaser of all or substantially all of its assets;
or (b) any person
 
                                        7
<PAGE>   47
 
acquires more than 50 percent of the total voting power entitled to vote for
directors of the Company. Except as may otherwise be set forth in the
accompanying Prospectus Supplement, the Company's failure to comply with the
Change of Control covenant as to the Offered Debt Securities will be an Event of
Default under the Indenture for the Offered Debt Securities, as specified in the
accompanying Prospectus Supplement. See "Events of Default" below. The meaning
of the term "all or substantially all of the assets" has not been definitely
established and is likely to be interpreted by reference to applicable state law
if and at the time the issue arises and will be dependent on the facts and
circumstances existing at the time. Accordingly, there may be uncertainty as to
whether a holder of Offered Debt Securities can determine whether a Change of
Control has occurred and exercise any remedies such holder may have upon a
Change of Control. Except as described above with respect to a Change of Control
or as described in the accompanying Prospectus Supplement, the Indenture for the
Offered Debt Securities will not afford holders of the Debt Securities
protection in the event of a highly leveraged transaction, takeover,
reorganization, restructuring, recapitalization, merger or similar transaction
involving the Company that may adversely affect holders of the Debt Securities.
 
     MERGER, CONSOLIDATION, SALE, LEASE OR CONVEYANCE.  Except as may otherwise
be provided in the accompanying Prospectus Supplement, the Indenture for the
Offered Debt Securities will provide that the Company will not merge or
consolidate with or into any other person and will not sell, lease or convey all
or substantially all of its assets to any person, unless it is the continuing
corporation, or the successor corporation or person that acquires all or
substantially all of its assets is a corporation organized and existing under
the laws of the United States or a State thereof or the District of Columbia and
expressly assumes all of the Company's obligations under the Offered Debt
Securities and the Indenture for the Offered Debt Securities and, immediately
after such merger, consolidation, sale, lease or conveyance, such person or such
successor corporation is not in default in the performance of the covenants and
conditions in the Indenture for the Offered Debt Securities. With respect to
possible uncertainties concerning the meaning of the term "all or substantially
all of the assets", the possible lack of protection in a highly leveraged merger
or other transaction and related possible effects on holders of the Debt
Securities, see "Change of Control" above.
 
REDEMPTION
 
     If and to the extent set forth in the accompanying Prospectus Supplement,
the Company will have the right to redeem the Offered Debt Securities, in whole
or from time to time in part, after the date and at the redemption prices set
forth in the accompanying Prospectus Supplement.
 
EVENTS OF DEFAULT
 
     Except as may be described in the accompanying Prospectus Supplement, an
"Event of Default" will be defined under the Indenture for the Offered Debt
Securities as being: (a) default for 30 days in payment of any interest on the
Offered Debt Securities; (b) default in payment of any principal of the Offered
Debt Securities, either at maturity (or upon any redemption), by declaration or
otherwise; (c) default for 60 days after written notice in the performance of
any other agreements or covenants in, or provisions of, the Offered Debt
Securities or the Indenture for the Offered Debt Securities; (d) an event of
default 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 and certain of its subsidiaries (or the payment of which
is guaranteed by the Company), other than non-recourse Indebtedness, if (i)
either (1) such event of default results from the failure to pay any such
Indebtedness at maturity and such default has not been cured or such
acceleration rescinded or (2) as a result of such event of default, the maturity
of such Indebtedness has been accelerated prior to its expressed maturity and
(ii) the principal amount of such Indebtedness, together with the principal
amount of any other such Indebtedness in default for failure to pay principal at
maturity or the maturity of which has been so accelerated and the acceleration
of which has not been rescinded, equals or exceeds the amount specified in the
accompanying Prospectus Supplement; (e) failure for 60 days to discharge final
judgments against the Company and certain of its subsidiaries for the payment of
money aggregating the amount specified in the accompanying Prospectus Supplement
or more; and (f) certain events of bankruptcy, insolvency or reorganization.
 
                                        8
<PAGE>   48
 
     The Indenture for the Offered Debt Securities will provide that if an Event
of Default (other than an Event of Default due to certain events of bankruptcy,
insolvency or reorganization) has occurred and is continuing, either the Trustee
or the holders of not less than 25 percent in principal amount of the Offered
Debt Securities outstanding under the Indenture for the Offered Debt Securities,
or such other amount as may be specified in the Prospectus Supplement, may then
declare the principal of all Offered Debt Securities under that Indenture and
interest accrued thereon to be due and payable immediately.
 
     Except to the extent otherwise stated in the accompanying Prospectus
Supplement, the Indenture for the Offered Debt Securities will contain a
provision entitling the Trustee, subject to the duty of the Trustee during a
default to act with the required standard of care, to be indemnified by the
holders of Offered Debt Securities before proceeding to exercise any right or
power under that Indenture at the request of such holders. Subject to such
provisions in the Indenture for the Offered Debt Securities for the
indemnification of the Trustee and certain other limitations, the holders of a
majority in principal amount of the Offered Debt Securities then outstanding 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 the
Trustee.
 
     Except to the extent otherwise stated in the accompanying Prospectus
Supplement, the Indenture for the Offered Debt Securities will provide that no
holder of Offered Debt Securities may institute any action against the Company
under the Indenture (except actions for payment of overdue principal or
interest) unless (a) such holder previously has given the Trustee written notice
of the default and continuance thereof, (b) the holders of not less than 25
percent in principal amount of the Offered Debt Securities then outstanding have
requested the Trustee to institute such action and offered the Trustee
reasonable indemnity, (c) the Trustee has not instituted such action within 60
days of the request and (d) the Trustee has not received direction inconsistent
with such written request from the holders of a majority in principal amount of
the Offered Debt Securities then outstanding under the Indenture.
 
     The Indentures and the Debt Securities will provide that no director,
officer, employee or shareholder of the Company, as such, will have any
liability for any obligations of the Company under the Debt Securities or the
Indentures. The Indentures and the Debt Securities will also each provide that
each holder of the Debt Securities, by accepting the Debt Securities, waives and
releases all such liability.
 
DEFEASANCE AND DISCHARGE
 
     Except as may otherwise be provided in the accompanying Prospectus
Supplement, the Company can discharge or defease its obligations under the
Indenture for the Offered Debt Securities as set forth below.
 
     Under terms satisfactory to the Trustee, the Company may discharge certain
obligations to holders of the Offered Debt Securities that have not already been
delivered to the Trustee for cancellation and that have either become due and
payable or are by their terms due and payable within one year (or scheduled for
redemption within one year) by irrevocably depositing with the Trustee cash or
United States Government Obligations (as defined in the Indenture for the
Offered Debt Securities), or a combination thereof, as trust funds in an amount
certified to be sufficient to pay at maturity (or upon redemption) the principal
of and interest on such Offered Debt Securities.
 
     The Company may also discharge any and all of its obligations to holders of
the Offered Debt Securities at any time ("defeasance"), but may not thereby
avoid its duty to register the transfer or exchange of the Offered Debt
Securities, to replace any temporary, mutilated, destroyed, lost or stolen
Offered Debt Securities or to maintain an office or agency in respect of such
Offered Debt Securities and certain other obligations. Alternatively, the
Company may be released with respect to the Offered Debt Securities from the
obligations imposed by specific portions of the Indenture for the Offered Debt
Securities (including the covenant described above limiting consolidations,
mergers, asset sales and leases) and omit to comply with such provisions without
creating an Event of Default ("covenant defeasance"). Defeasance or covenant
defeasance may be effected only if, among other things: (a) the Company
irrevocably deposits with the Trustee cash or United States Government
Obligations, or a combination thereof, as trust funds in an amount certified to
be sufficient to pay at maturity the principal of and interest on all
outstanding Offered Debt Securities; (b) no Event of Default under the Indenture
for the Offered Debt Securities has occurred and is then continuing;
                                        9
<PAGE>   49
 
(c) the defeasance or covenant defeasance will not result in an event of default
under any agreement to which the Company is a party or by which it is bound; and
(d) the Company delivers to the Trustee an opinion of counsel to the effect that
the holders of Debt Securities will not recognize income, gain or loss for
federal income tax purposes as a result of such defeasance or covenant
defeasance and that such defeasance or covenant defeasance will not otherwise
alter such holders' federal income tax treatment of principal and interest
payments on the Offered Debt Securities.
 
MODIFICATIONS TO THE INDENTURES
 
     Except as may otherwise be set forth in the accompanying Prospectus
Supplement, the Indenture for the Offered Debt Securities will provide that the
Company and the Trustee may enter into supplemental indentures without the
consent of the holders of Offered Debt Securities to, among other things: (a)
add covenants, conditions and restrictions for the protection of the holders of
Offered Debt Securities or to surrender any right of the Company; (b) cure any
ambiguity or correct any inconsistency in the Indenture for the Offered Debt
Securities; (c) make any change that does not adversely affect the legal rights
of holders of Offered Debt Securities; (d) modify, eliminate or add to the
provisions of the Indenture for the Offered Debt Securities to the extent
necessary to qualify that Indenture under applicable federal statutes; or (e)
make any other changes in the Indenture before Offered Debt Securities are
issued thereunder, provided that such changes are not prohibited by the Trust
Indenture Act.
 
     Except as may otherwise be set forth in the accompanying Prospectus
Supplement, the Indenture for the Offered Debt Securities also will contain
provisions permitting the Company and the Trustee, with the consent of the
holders of not less than a majority in principal amount of Offered Debt
Securities outstanding, to add any provision to, change in any manner or
eliminate any of the provisions of the Indenture for the Offered Debt Securities
or modify in any manner the rights of the holders of the Offered Debt Securities
so affected; provided that the Company and the Trustee may not, without the
consent of the holder of each outstanding Offered Debt Security affected
thereby, do, among other things, any of the following: (a) reduce the amount of
Offered Debt Securities whose holders must consent to an amendment, supplement
or waiver with respect to the Indenture; (b) reduce the rate of or change the
time for payment of interest on any Offered Debt Security; (c) reduce the
principal of or change the fixed maturity of any Offered Debt Security; or (d)
waive a default in the payment of the principal of, or interest on, any Offered
Debt Security.
 
     The Indentures for senior subordinated or subordinated Offered Debt
Securities may not be amended to alter the subordination of any outstanding
senior subordinated or subordinated Debt Securities without the consent of each
holder of Senior Debt and, as to subordinated Debt Securities, also senior
subordinated debt then outstanding that would be adversely affected thereby.
 
CONCERNING THE TRUSTEE
 
     State Street Bank and Trust Company is the Trustee under the indenture for
the Company's $150 million of 9 3/4% Senior Subordinated Debentures due 2008.
Unless stated in the applicable Prospectus Supplement, (i) it or any other
Trustee may also be the Trustee under any indenture for Offered Debt Securities
and (ii) any Trustee or its affiliates may be a lender to the Company, including
under its principal credit facility, and may time to time have lender or other
business arrangements with the Company. The Indenture will contain certain
limitations on the rights of the Trustee, should it or its affiliates then be
creditors of the Company, to obtain payment of claims in certain cases or to
realize on certain property received in respect of any such claim as security or
otherwise. The Trustee and its affiliates will be permitted to engage in other
transactions; however, if they acquire any conflicting interest, the conflict
must be eliminated or the Trustee must resign.
 
     The Holders of a majority in principal amount of the then outstanding Debt
Securities issued under any Indenture will have the right to direct the time,
method and place of conducting any proceeding for exercising any remedy
available to the Trustee under that Indenture, subject to certain exceptions.
Unless otherwise stated in the applicable Prospectus Supplement, the Indentures
will provide that in case an Event of Default occurs and is not cured, the
Trustee will be required, in the exercise of its power, to use the degree of
care of a
 
                                       10
<PAGE>   50
 
prudent person in similar circumstances in the conduct of his, her or its
affairs. Subject to such provisions, the Trustee will be under no obligation to
exercise any of its rights or powers under any Indenture at the request of any
Holder, unless such Holder has offered the Trustee security and indemnity
satisfactory to the Trustee.
 
GOVERNING LAW
 
     Unless otherwise specified in the accompanying Prospectus Supplement, the
Indenture for the Offered Debt Securities and the Offered Debt Securities will
be governed by New York law.
 
                            DESCRIPTION OF WARRANTS
 
GENERAL
 
     Except as otherwise set forth in the accompanying prospectus supplement,
the Warrants will be issued in fully registered form under a Warrant Agreement
between the Company and the Warrant Agent named in the accompanying Prospectus
Supplement (the "Warrant Agent"). The statements in this Prospectus relating to
the Warrants and the Warrant Agreement are summaries and do not purport to be
complete.
 
     Each Warrant will entitle the registered owner (the "Warrantholder") to
purchase one share of Preferred or Common Stock, as set forth in the
accompanying Prospectus Supplement, subject to the call provisions referred to
below, from the time the Warrants are separately transferable until the date set
forth in the accompanying Prospectus Supplement. The initial per share exercise
price of the Warrants and the date on which the Warrants become separately
transferable will be set forth in the applicable Prospectus Supplement.
 
     The Warrants can be exercised by surrendering to the Warrant Agent a
Warrant certificate signed by the Warrantholder or his, her or its duly
authorized agent indicating the Warrantholder's election to exercise all or a
portion of the Warrants evidenced by the certificate. Surrendered Warrant
certificates must be accomplished by payment of the aggregate exercise price of
the Warrants to be exercised (the "Warrant Price"), which payment may be made in
the form of cash or a cashier's check equal to the exercise price or, if and to
the extent set forth in the accompanying Prospectus Supplement, the surrender of
Debt Securities in denominations at least equal to the aggregate Warrant Prices
or, if applicable, any combination of cash and such denominations of Debt
Securities. If the principal amount of Debt Securities surrendered is in excess
of the aggregate Warrant Price so paid, only a portion of such surrendered
principal amount shall be accepted against payment of the Warrant Price and new
Debt Securities shall be issued in the principal amount not so applied against
the aggregate Warrant Price, provided that the amount of such excess is $1,000
or an integral multiple thereof.
 
     Certificates evidencing duly exercised Warrants shall be delivered by the
Warrant Agent to the transfer agent for the Preferred or Common Stock, as
applicable. Upon receipt thereof, the transfer agent will be obligated to
deliver or cause to be delivered, to or upon the written order of the exercising
Warrantholders, certificates representing the number of shares of Preferred or
Common Stock so purchased. If fewer than all of the Warrants evidenced by any
certificate are exercised, the Warrant Agent will be obligated to deliver to the
exercising Warrantholder a new Warrant certificate representing the unexercised
Warrants.
 
     To the extent set forth in the accompanying Prospectus Supplement, the
Warrant Price and the number of shares of Preferred or Common Stock purchasable
upon the exercise of each Warrant are subject to adjustment in certain events,
including: (i) the issuance of a stock dividend to holders of Preferred Stock or
Common Stock (whichever the Warrants are exercisable for) or a combination,
subdivision, or reclassification of the Preferred Stock or the Common Stock
(whichever the Warrants are exercisable for); (ii) the issuance of rights,
warrants or options or securities convertible into, or exchangeable for, the
Preferred Stock or the Common Stock (whichever the Warrants are exercisable
for), that are distributed to all holders of the Company's outstanding Preferred
or Common Stock (whichever the Warrants are exercisable for) entitling them to
subscribe for or purchase Preferred or Common Stock; and (iii) any distribution
by the Company to the holders of its Preferred or Common Stock (whichever the
Warrants are exercisable for) of evidences of indebtedness of the Company or of
assets (excluding, if and to the extent set forth in the accompanying
 
                                       11
<PAGE>   51
 
Prospectus Supplement, certain cash dividends or distributions). To the extent
set forth in the accompanying Prospectus Supplement, no adjustment in the number
of shares purchasable upon exercise of the Warrants or in the Warrant Price will
be required until cumulative adjustments require an adjustment of at least one
percent thereof. In addition, unless the accompanying Prospectus Supplement
states to the contrary, the Company may, at its option, reduce the Warrant Price
at any time. No fractional shares will be issued upon exercise of Warrants, but
the Company will pay the cash value of any fractional shares otherwise issuable.
 
     Notwithstanding the foregoing, unless the accompanying Prospectus
Supplement states to the contrary, in case of any consolidation, merger or sale
or conveyance of the property of the Company and its subsidiaries as a whole,
including a consolidation or merger in which the Company is the continuing
corporation and in which all or a majority of the Preferred and Common Stock
outstanding immediately prior to the consolidation or merger is converted into
consideration other than capital stock (or the right to receive such
consideration), the holder of each outstanding Warrant shall have the right to
exercise the Warrant for the kind and amount of shares of stock and other
securities and property (including cash) receivable by a holder of the number of
shares of Preferred and Common Stock for which such Warrant was exercisable
immediately prior thereto.
 
     Adjustments to the Warrant Price (and, possibly, adjustment to the number
of shares of Preferred or Common Stock purchasable upon the exercise of each
Warrant), or the failure to make such adjustments, may in certain circumstances
result in distributions that could be taxable as dividends under the Internal
Revenue Code of 1986, as amended, to holders of the Warrants or to holders of
shares of Preferred or Common Stock issued upon exercise thereof. The Company
will reserve the right (but will not be obligated) to make such adjustments to
the Warrant Price or in the number of shares of Preferred or Common Stock
purchasable upon the exercise of each Warrant, in addition to those required in
the foregoing provisions, as it shall determine to be advisable in order that
certain stock-related distributions which may hereafter be made by the Company
to its stockholders after the date of the accompanying Prospectus Supplement
shall not be taxable to them.
 
     If all or any portion of the Warrants are callable at the option of the
Company, the call provisions, including the call price and the date through
which the Warrants may be exercised, will be set forth in the accompanying
Prospectus Supplement. If upon expiration the unexercised Warrants will convert
into Preferred or Common Stock, the manner and rate of such conversion will be
set forth in the accompanying Prospectus Supplement.
 
     Holders of Warrants are not entitled, by virtue of being holders, to
receive dividends or to consent or to receive notice as stockholders in respect
of any meeting of stockholders for the election of directors of the Company or
any other matter, to vote at any such meeting or to exercise any rights
whatsoever as stockholders of the Company. The Warrant Agreement and the
Warrants will provide that no director, officer, employee or shareholder of the
Company, as such, will have any liability under the Warrants or the Warrant
Agreement. The Warrant Agreement and the Warrants will also each provide that
each holder of the Warrants, by accepting the Warrants, waives and releases all
such liability.
 
     Unless otherwise specified in the accompanying Prospectus Supplement, the
Warrant Agreement and the Warrants will be governed by New York law.
 
                          DESCRIPTION OF CAPITAL STOCK
 
     The authorized capital stock of the Company consists of 30,000,000 shares
of Common Stock, $.001 par value, and 10,000,000 shares of Preferred Stock,
$.001 par value, of which 17,566,609 shares of Common Stock (exclusive of
treasury shares) were issued and outstanding on June 30, 1997. No shares of
Preferred Stock were outstanding at that date.
 
COMMON STOCK
 
     Subject to the rights of holders of any outstanding Preferred Stock, the
holders of outstanding shares of Common Stock are entitled to share ratably in
dividends declared out of assets legally available therefor at
                                       12
<PAGE>   52
 
such time and in such amounts as the Board of Directors may from time to time
lawfully determine. At the date of this Prospectus the payment of dividends on
the Common Stock is limited by provisions of the Indentures for the Company's
$100 million of 9 3/4% Senior Subordinated Debentures due March 1, 2003, $100
million of 9% Senior Subordinated Debentures due February 15, 2006 and $150
million of 9 3/4% Senior Subordinated Debentures due 2008 and its principal
credit facility.
 
     Each holder of Common Stock is entitled to one vote for each share held by
him. Holders of Common Stock are not entitled to cumulate votes for the election
of directors. The Common Stock is not entitled to conversion or preemptive
rights and is not subject to redemption or assessment. Subject to the rights of
holders of any outstanding Preferred Stock, upon liquidation, dissolution or
winding up of the Company, any assets legally available for distribution to
shareholders as such are to be distributed ratably among the holders of the
Common Stock at that time outstanding. The Common Stock presently outstanding
is, and the Common Stock issued upon conversion of the Debt Securities, exercise
of the Warrants (upon payment in full of the Warrant exercise price) or
conversion of any convertible Preferred Stock offered hereby, as the case may
be, will be, fully paid and nonassessable. The Common Stock is listed on the New
York and Pacific Stock Exchanges.
 
PREFERRED STOCK
 
     The authorized shares of Preferred Stock are issuable, without further
shareholder approval, in one or more series as determined by the Board of
Directors, with such rights, privileges and preference as are fixed by the Board
of Directors, including dividend, liquidation and other rights preferred over
the Common Stock, subject to the restrictions in the Indentures and credit
facility referred to above. The Preferred Stock issuable upon exercise of any
Warrants exercisable for Preferred Stock (upon payment in full of the Warrant
exercise price) or conversion of any Debt Securities convertible into Preferred
Stock will be fully paid and nonassessable. The Preferred Stock may be
convertible and, if so convertible, may be converted into one or both of Common
Stock and Debt Securities. The Preferred Stock may also be exchangeable, at the
option of the Company, for Debt Securities (see "Description of Debt
Securities"). If Preferred Stock or Warrants exercisable for Preferred Stock are
being offered or if the Preferred Stock is exchangeable for Debt Securities, the
accompanying Prospectus Supplement will describe the rights, privileges,
preferences and restrictions of such Preferred Stock (including, without
limitation, the designation, the number of authorized shares of the series in
question, the dividend rate (or method of calculation), any voting rights,
conversion rights, anti-dilution protections, exchangeability provisions and
terms of the Debt Securities that are exchangeable for the Preferred Stock, any
redemption provisions, liquidation preferences and any sinking fund provisions).
If fractional interests in shares of Preferred Stock may be issued, there will
be a depositary for the shares of Preferred Stock involved and the applicable
Prospectus Supplement will describe the terms of the depositary arrangement and
related matters.
 
                              PLAN OF DISTRIBUTION
 
     The Company may sell the Securities to one or more underwriters for public
offering and sale by them or may sell the Securities to investors directly or
through agents. Any such underwriter or agent involved in the offer and sale of
the Securities will be named in the applicable Prospectus Supplement. The
Company may sell Securities directly to investors on its own behalf in those
jurisdictions where it is authorized to do so.
 
     Underwriters may offer and sell the Securities at a fixed price or prices,
which may be changed, at market prices prevailing at the time of sale, at prices
related to such prevailing market prices or at negotiated prices. The Company
also may, from time to time, authorize dealers, acting as Company agents, to
offer and sell the Securities upon such terms and conditions as may be set forth
in the Prospectus Supplement. In connection with the sale of the Securities,
underwriters may receive compensation from the Company in the form of
underwriting discounts or commissions and may also receive commissions from
purchasers of the Securities for whom they may act as agent. Underwriters may
sell the Securities to or through dealers, and such dealers may receive
compensation in the form of discounts, concessions or commissions from the
underwriters or commissions from the purchasers for which they may act as
agents.
 
                                       13
<PAGE>   53
 
     Any underwriting compensation paid by the Company to underwriters or agents
in connection with the offering of the Securities, and any discounts or
concessions or commissions allowed by underwriters to participating dealers,
will be set forth in the applicable Prospectus Supplement. Dealers and agents
participating in the distribution of the Securities may be deemed to be
underwriters, and any discounts and commissions received by them and any profit
realized by them on resale of the Securities may be deemed to be underwriting
discounts and commissions. Underwriters, dealers and agents may be entitled,
under agreements entered into with the Company, to indemnification against and
contribution toward certain civil liabilities.
 
     The Debt Securities, the Preferred Stock and the Warrants will be new
issues of securities with no established trading market. Any underwriters or
agents to or through which Securities are sold by the Company for public
offering and sale may make a market in such Securities, but such underwriters or
agents will not be obligated to do so and any of them may discontinue any market
making at any time without notice. No assurance can be given as to the liquidity
of or trading market for any Debt Securities, Preferred Stock or Warrants.
 
                             CERTAIN LEGAL MATTERS
 
     Gibson, Dunn & Crutcher LLP has rendered an opinion (filed as an exhibit to
the Registration Statement) with respect to the validity of the Debt Securities,
Preferred Stock, Common Stock and Warrants covered by this Prospectus. The
partner of Gibson, Dunn & Crutcher LLP who has primary responsibility for that
firm's work in connection with the Registration Statement beneficially owns

         PRIVATE PLACEMENT IN CANADA OF SENIOR SUBORDINATED DEBENTURES
 
THE OFFERING
 
     The Senior Subordinated Debentures (the "Debentures") being offered in
Canada are part of an offering of $200,000,000 of Debentures of Del Webb
Corporation (the "Company").
 
     Attached hereto is a copy of the Prospectus dated October 29, 1997 and
accompanying Prospectus Supplement filed with the Securities and Exchange
Commission in the United States regarding the offering being made in the United
States. The offering in Canada is being made solely in the Provinces of Ontario,
Manitoba, Saskatchewan and Alberta.
 
RESALE RESTRICTIONS
 
     The distribution of Debentures in Canada is being made on a private
placement basis. Accordingly, any resale of such Debentures must be made in
accordance with an exemption from the registration and prospectus requirements
of applicable securities laws, which vary depending on the province. Purchasers
of the Debentures are advised to seek legal advice prior to any resale of the
Debentures.
 
REPRESENTATION BY PURCHASERS
 
     Confirmations of the acceptance of offers to purchase the Debentures will
be sent to purchasers in Canada who have not withdrawn their offers to purchase
prior to the issuance of such confirmations. Each purchaser who receives a
purchase confirmation will, by the purchaser's receipt thereof, be deemed to
represent to the Company and the dealer from whom such purchase confirmation is
received that such purchaser is entitled under applicable provincial securities
laws to purchase such Debentures without the benefit of a prospectus qualified
under such securities laws.
 
CANADIAN FEDERAL INCOME TAX CONSIDERATIONS
 
     The following summary is a general discussion of the principal Canadian
federal income tax considerations generally applicable to a purchaser of
Debentures pursuant to this Offering who, for the purposes of the Income Tax Act
(Canada)(the "Act"), is resident in Canada, deals at arm's length with the
Company, is not a financial institution to which the mark-to-market rules may be
applicable and holds the Debentures as capital property.
 
     This summary is based on the current provisions of the Act and the
regulations thereunder, all specific proposals to amend the Act and the
regulations announced or released by the Minister of Finance, Canada prior to
the date hereof and the published administrative practices of Revenue Canada.
This summary does not otherwise take into account or anticipate any changes in
law, whether by judicial, governmental or legislative decision or action, nor
does it take into account provincial, territorial, or foreign income tax
considerations which may differ from the Canadian federal income tax
considerations described herein.
 
     THIS SUMMARY IS NOT EXHAUSTIVE OF ALL FEDERAL INCOME TAX CONSIDERATIONS
THAT MAY BE RELEVANT TO A PARTICULAR HOLDER OF DEBENTURES IN LIGHT OF THE
HOLDER'S PARTICULAR CIRCUMSTANCES. THIS SUMMARY IS NOT INTENDED TO BE, AND
SHOULD NOT BE INTERPRETED AS, LEGAL OR TAX ADVICE TO ANY PARTICULAR HOLDER OF
DEBENTURES, AND NO REPRESENTATION WITH RESPECT TO THE INCOME TAX CONSEQUENCES TO
ANY PARTICULAR HOLDER IS MADE. ACCORDINGLY, PROSPECTIVE PURCHASERS OF DEBENTURES
SHOULD CONSULT THEIR OWN TAX ADVISORS WITH RESPECT TO THEIR PARTICULAR
CIRCUMSTANCES.
 
     All amounts relating to the acquisition, holding or disposition of
Debentures and the inclusion in income of interest thereon in a taxation year
must be converted into Canadian dollars for the purposes of the Act and the
regulations thereunder at the exchange rate applicable to the relevant time or
taxation year.
<PAGE>   57
 
     INTEREST:  A holder of a Debenture that is a corporation, a partnership, a
unit trust or any trust of which a corporation or partnership is a beneficiary
will be required to include in income for a taxation year all interest on the
Debenture accrued to the holder to the end of that taxation year, or that became
receivable or was received by the holder before the end of that taxation year,
to the extent that such interest was not included in the holder's income for a
preceding taxation year. A Canadian-controlled private corporation (as defined
in the Act) may also be liable to pay a 6 2/3% refundable tax on certain
investment income, including interest and "taxable capital gains". (See "Capital
Gains and Capital Losses" below for a discussion of taxable capital gains.) Any
other holder of a Debenture (other than a holder referred to above) will be
required to include in income for a taxation year the amount of interest
received or receivable on the Debenture in that taxation year (depending upon
the method regularly followed by the holder in computing income) and will be
required to include in income any interest that accrued to the holder on a
Debenture up to any anniversary day (as defined in the Act) in that year to the
extent that such interest was not included in the holder's income for the year
or a preceding taxation year.
 
     On a redemption or repurchase of a Debenture by the Company at or before
maturity, or on an assignment or other transfer of a Debenture, a holder will
generally be required to include in income for the taxation year in which the
redemption, repurchase, assignment or other transfer occurs, an amount equal to
the accrued and unpaid interest on the Debenture to the date of such redemption,
repurchase, assignment or other transfer, to the extent that such amount has not
otherwise been included in the holder's income for the year or a preceding
taxation year. In such circumstances, a holder of a Debenture will also be
entitled to deduct the amount, if any, by which the amount included in income as
interest pursuant to the Act and the regulations exceeds all amounts received or
receivable that can reasonably be considered to be in respect of interest on the
Debentures.
 
     CAPITAL GAINS AND CAPITAL LOSSES:  Where a holder of a Debenture disposes
of a Debenture (including on the redemption by the Company), the holder will
realize a capital gain (or a capital loss) to the extent the holder's proceeds
of disposition of the Debenture exceed (or are less than) the aggregate of (i)
the amount of accrued and unpaid interest on the Debenture included in the
holder's income to the date of the disposition, (ii) the holder's adjusted cost
base of the Debenture, and (iii) reasonable costs of disposition.
 
     Three-quarters of any capital gain (a "taxable capital gain") will be
included in the holder's income and three-quarters of any such capital loss will
be deductible from taxable capital gains in accordance with the provisions of
the Act. A capital gain realized by an individual may give rise to liability for
alternative minimum tax.
 
     FOREIGN TAX CREDITS:  Subject to certain limitations, a holder may be
entitled to claim a credit or a deduction in computing such holder's Canadian
tax liability for any United States withholding or other income tax payable by
the holder in respect of interest received on, or any gain realized on a
disposition of, the Debentures.
 
     FOREIGN PROPERTY:  The Debentures will be "foreign property" for the
purposes of the tax imposed on certain deferred income plans under Part XI of
the Act.
 
ENFORCEMENT OF LEGAL RIGHTS
 
     ONTARIO:  The Debentures being offered are those of a foreign issuer and
Ontario purchasers will not receive the contractual right of action prescribed
by section 32 of the Regulation under the Securities Act (Ontario). As a result,
Ontario purchasers must rely on other remedies that may be available, including
common law rights of action for damages or rescission or rights of action under
the civil liability provisions of the U.S. federal securities laws.
 
     All of the Company's directors and officers and the experts named in the
Prospectus and Prospectus Supplement may be located outside Canada and, as a
result, it may not be possible for Canadian purchasers to effect service of
process within Canada upon the Company or such persons. All or a substantial
portion of the assets of the Company and such persons may be located outside of
Canada and, as a result, it may not be
<PAGE>   58
 
possible to satisfy a judgment against the Company or such persons in Canada or
to enforce a judgment obtained in Canadian courts against the Company or such
persons outside of Canada.
 
     SASKATCHEWAN:  The Securities Act, 1988 (Saskatchewan) provides purchasers
with certain statutory rights of action, including: (a) if the prospectus or any
amendment thereto contains a misrepresentation, which was a misrepresentation at
the time of purchase (i) a right of action for damages or rescission against the
Company and any Selling Stockholders, (ii) a right of action for damages against
every promoter and director of the Company or any Selling Stockholders, as the
case may be, who was a promoter or director at the time the prospectus or any
amendment thereto was sent or delivered and (iii) a right of action for damages
against the dealer from whom the Debentures were purchased; (b) a right of
action for damages against any individual who makes a verbal misrepresentation
to such Saskatchewan purchaser prior to or contemporaneously with the purchase
of Debentures; (c) a right to void the agreement to purchase the Debentures and
recover the purchase price if the Debentures are sold in contravention of the
Act, the regulations under the Act or a decision of the Saskatchewan Securities
Commission; and (d) a right of action for damages or rescission if a copy of
this notice, the attached Prospectus or Prospectus Supplement, or any amendment
to either of them, was not delivered to such purchaser before the Debentures
were subscribed for.
 
     An action for damages must be started by the earlier of (a) one year after
the investor first had knowledge of the facts giving rise to the action or (b)
six years after the date of the transaction that gave rise to the action. An
action for rescission must be commenced by 180 days after the date of the
transaction that gave rise to the action.
 
     The rights available to Saskatchewan purchasers are in addition to and
without derogation from any other right or remedy which such purchasers may have
at law, are intended to correspond to the provisions of the Act and are subject
to the defences contained therein.
