                              THE SECURITIES

SECTION 2.01.     FORM AND DATING.

    The Securities and the Trustee's certificate of authentication relating
thereto shall be substantially in the form set forth in Exhibit A, which is part
of this Indenture, with such appropriate insertions, omissions, substitutions
and other variations as are required or permitted by this Indenture, provided
that the Securities may be Global Securities and as such may be issued in either
registered or bearer form. The Securities may have notations, legends or
endorsements required by law, stock exchange rule or usage. The Company shall
approve the forms of the Securities and any notation, legend or endorsement on
them. Each Security shall be dated the date of its authentication.

    The terms and provisions contained in the Securities shall constitute, and
are hereby expressly made, a part of this Indenture and, to the extent
applicable, the Company and the Trustee, by their execution and delivery of this
Indenture, expressly agree to such terms and provisions and to be bound thereby.

SECTION 2.02.     EXECUTION AND AUTHENTICATION.

    Two Officers shall sign the Securities for the Company by manual or
facsimile signature. The Company's seal shall be reproduced on the Securities.

    If an Officer whose signature is on a Security no longer holds that office
at the time the Security is authenticated, the Security shall nevertheless be
valid.

    A Security shall not be valid until authenticated by the manual signature of
the Trustee. The signature shall be conclusive evidence that the Security has
been authenticated under this Indenture.

    Upon a written order of the Company signed by an Officer of the Company, the
Trustee shall authenticate Securities for original issue up to $________ in
aggregate principal amount. The aggregate principal amount of Securities
outstanding at any time may not exceed that amount except as provided in Section
2.07.

                                       6
   15
    The Securities shall be issuable only in registered form without coupons and
only in denominations of $1,000 or any integral multiple thereof.

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

SECTION 2.03      REGISTRAR AND PAYING AGENT.

    The Company shall maintain or cause to be maintained in the Borough of
Manhattan, City of New York (the "New York Office"), State of New York, and in
such other locations as it shall determine: (i) an office or agency where
securities may be presented for registration of transfer or for exchange
("Registrar"); [and] (ii) an office or agency where Securities may be presented
for payment ("Paying Agent")[; and (iii) an office or agency where Securities
may be presented for conversion ("Conversion Agent")]. The Registrar shall keep
a register of the Securities and of their transfer and exchange. The Company may
appoint one or more co-registrars[, and] one or more additional paying agents
[and one or more additional conversion agents]. The term "Paying Agent" includes
any additional paying agent[; and the term "Conversion Agent" includes any
additional conversion agent]. The Company may change any Paying Agent,
Registrar[, or] co-registrar [or Conversion Agent] without prior notice. The
Company shall notify the Trustee of the name and address of any Agent not a
party to this Indenture and shall enter into an appropriate agency agreement
with any Registrar, Paying Agent[, or] co-registrar [or Conversion Agent] not a
party to this Indenture. The agreement shall implement the provisions of this
Indenture that relate to such Agent. The Company or any of its subsidiaries may
act as Paying Agent, Registrar[, or] co-registrar [or Conversion Agent]. If the
Company fails to appoint or maintain another entity as Registrar[, or] Paying
Agent[, or Conversion Agent], the Trustee shall act as such, and the Trustee
shall initially act as such. The Trustee shall cause to be maintained the New
York Office as long as it acts as Registrar[, or] Paying Agent [or Conversion
Agent].

SECTION 2.04.     PAYING AGENT TO HOLD MONEY IN TRUST.

    The Company shall require each Paying Agent (other than the Trustee, who
hereby so agrees), to agree in writing that the Paying Agent will hold in trust
for the benefit of Securityholders or the Trustee all money held by the Paying
Agent for the payment of principal or interest on the Securities, and will
notify the Trustee of any default by the Company in making any such payment.
While any such default continues, the Trustee may require



                                       7
   16
a Paying Agent to pay all money held by it to the Trustee. The Company at any
time may require a Paying Agent to pay all money held by it to the Trustee. Upon
payment over to the Trustee, the Paying Agent (if other than the Company or a
subsidiary) shall have no further liability for the money. If the Company or a
subsidiary acts as Paying Agent, it shall segregate and hold in a separate trust
fund for the benefit of the Securityholders all money held by it as Paying
Agent.

SECTION 2.05.     SECURITYHOLDER LISTS.

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

SECTION 2.06.     TRANSFER AND EXCHANGE.

    Where Securities are presented to the Registrar or a co-registrar with a
request to register a transfer or to exchange them for an equal principal amount
of Securities of other denominations, the Registrar shall register the transfer
or make the exchange if its requirements for such transactions are met. To
permit registrations of transfers and exchanges, the Company shall issue and the
Trustee shall authenticate Securities at the Registrar's request. No service
charge shall be made for any registration of transfer or exchange (except as
otherwise expressly permitted herein), but the Company may require payment of a
sum sufficient to cover any transfer tax or similar governmental charge payable
in connection therewith (other than any such transfer tax or similar
governmental charge payable upon exchanges pursuant to Sections 2.10, 3.06[, or]
9.05 [or 12.02]).

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

SECTION 2.07.     REPLACEMENT SECURITIES.

    If the Holder of a Security claims that the Security has been lost,
destroyed or wrongfully taken, the Company shall issue and the Trustee shall
authenticate a replacement Security if the Trustee's requirements are



                                       8
   17
met. If required by the Trustee or the Company as a condition of receiving a
replacement Security, the Holder must provide an indemnity bond sufficient, in
the judgment of both the Company and the Trustee, to fully protect the Company,
the Trustee, any Agent and any authenticating agent from any loss which any of
them may suffer if the Security is replaced. The Company may charge for its
expenses in replacing any Security.

    Every replacement Security is an additional obligation of the Company.

SECTION 2.08.     OUTSTANDING SECURITIES.

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

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

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

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

SECTION 2.09.     WHEN TREASURY SECURITIES DISREGARDED.

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

SECTION 2.10.     TEMPORARY SECURITIES.

    Until definitive Securities are ready for delivery, the Company may prepare
and the Trustee shall authenticate temporary Securities. Temporary Securities
shall be substantially in the form of definitive Securities but may have
variations that the Company considers appropriate for temporary Securities.
Without unreasonable delay, the Company shall prepare and the Trustee shall
authenticate definitive Securities in exchange for temporary Securities.

   18
SECTION 2.11.     CANCELLATION.

    The Company at any time may deliver Securities to the Trustee for
cancellation. The Registrar and Paying Agent shall forward to the Trustee any
Securities surrendered to them for registration of transfer, exchange or
payment. The Trustee and no one else shall cancel all Securities surrendered for
registration of transfer, exchange, payment, replacement or cancellation and
shall dispose of canceled Securities as the Company directs, provided that the
Trustee shall not be required to destroy such canceled securities. The Company
may not issue new Securities to replace Securities that it has paid or that have
been delivered to the Trustee for cancellation.

SECTION 2.12.     DEFAULTED INTEREST.

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

SECTION 2.13.     CUSIP NUMBER.

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

the Securities to be redeemed pro rata or by lot, if lawful, or if required by
another method that complies with the requirements of any exchange on which the
Securities are listed and that the Trustee considers fair and appropriate. The
Trustee shall make the selection not more than 75 days and not less than 45 days
before the redemption date from Securities outstanding not previously called for
redemption. The Trustee may select for redemption portions of the principal of
Securities that have denominations larger than $1,000. Securities and portions
of them it selects shall be in amounts of $1,000 or integral multiples of

        satisfy the requirements in paragraph 17 of the Securities; and

              (12)  the current conversion price.]

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

by rules and regulations prescribe) which the Company is required to file with
the SEC pursuant to Section 13 or 15(d) of the Exchange Act. The Company also
shall comply with the other provisions of TIA Section 314(a). The Company shall
timely comply with its reporting and filing obligations under the applicable
federal securities law.

    If the Company is at any time not required to file annual or quarterly
reports pursuant to Section 13 or 15(d) of the Exchange Act, the Company will
file with the Trustee, within 15 days after the last date on which it would have
been required to make such a filing with the SEC, and will upon



                                       13
   22
request of a Holder mail to that Holder (as soon as practical after receipt of
such request) at his or her address as it appears on the register of Securities
kept by the Registrar, audited annual financial statements prepared in
accordance with generally accepted accounting principles and unaudited quarterly
financial statements. Such financial statements shall be accompanied by a
Management's Discussion and Analysis of Financial Condition and Results of
Operations of the Company for the period reported upon in substantially the form
required under the rules and regulations of the SEC, or any successor form of
similar disclosure then required under the rules and regulations of the SEC.

SECTION 4.03.     COMPLIANCE CERTIFICATE.

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

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

    So long as not contrary to the then current recommendations of the American
Institute of Certified Public Accountants, at the time the Officers' Certificate
described in the second preceding paragraph is filed, the Company also will file
with the Trustee a letter or statement of the independent accountants who shall
have certified the financial statements of the Company for its preceding fiscal
year in connection with the annual report of the Company to its stockholders for
such year to the effect that, in making the examination necessary for
certification of such financial statements, nothing came to their attention that
would lead them to believe



                                       14
   23
that the Company has violated any of the terms or conditions contained in this
Indenture, which Default remains uncured at the date of such letter or statement
or, if they shall have obtained knowledge of any such uncured Default,
specifying in such letter or statement such Default or Defaults and the nature
thereof, it being understood that such accountants shall not be liable directly
or indirectly for failure to obtain knowledge of any such Default or Defaults
and that their examination was not directed primarily toward obtaining knowledge
of such noncompliance.

SECTION 4.04.     MAINTENANCE OF OFFICE OR AGENCY.

    The Company will maintain or cause to be maintained in the City of New York
an office or agency where Securities may be presented or surrendered for
payment, where Securities may be surrendered for registration of transfer or
exchange and where notices and demands to or upon the Company in respect of the
Securities and this Indenture may be served. The Company will give prompt
written notice to the Trustee of the location, and any change in the location,
of such office or agency not maintained by the Trustee. If at any time the
Company shall fail to maintain any such required office or agency or shall fail
to furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the address of the Trustee set
forth in Section 10.10.

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

SECTION 4.05.     RESTRICTIONS ON DIVIDENDS AND OTHER PAYMENTS.

    The Company shall not, directly or indirectly:

               (1) declare or pay any dividend on, or make any distribution to
        the holders (as such) of, any shares of its capital stock (other than
        dividends or distributions payable in Equity Interests (other than
        Disqualified Stock) of the Company);

               (2) purchase, redeem or otherwise acquire or retire for value any
        Equity Interests of the Company (other than any such Equity Interests
        owned by any subsidiary); or

                                       15
   24
               (3) permit any subsidiary to purchase, redeem or otherwise retire
        for value any Equity Interests of the Company (other than any such
        Equity Interests owned by any subsidiary) (such dividends,
        distributions, purchases, redemptions or other acquisitions or
        retirements referred to in clauses (1), (2) or (3) being collectively
        referred to as "Restricted Payments"), if at the time of such Restricted
        Payment:

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

                      (ii) if, upon giving effect to such Restricted Payment,
               the aggregate amount expended (determined as set forth below) for
               all such Restricted Payments subsequent to the date hereof, shall
               exceed the sum of:

                             (a) a percentage of the aggregate Consolidated Net
                      Earnings of the Company (or, in the case such aggregate
                      shall be a loss, 100% of such loss) accrued during fiscal
                      quarters ending subsequent to a specified date, which
                      percentage and date will be set forth in a supplemental
                      indenture;

                             (b) the aggregate net proceeds, including cash, the
                      fair market value of property other than cash (as
                      determined by the Board of Directors as evidenced by a
                      Board resolution) and the amount of any Indebtedness
                      (including principal, premium and interest), received by
                      the Company from or in exchange for the issue or sale
                      (other than to a subsidiary), subsequent to the date
                      hereof, of capital stock of the Company (other than
                      Disqualified Stock), other than in connection with the
                      exchange of the Securities;

                             (c)  the    amount    expended   for   the
                      purchase,  redemption  or  other  acquisition  or
                      retirement  for value of any  preferred  stock of
                      the Company; and

                             (d)  [$_________]  [or]  [the  amount  set
                      forth in a supplemental indenture].

For purposes of any calculation pursuant to the preceding sentence which is
required to be made within 60 days after the declaration of a dividend by the
Company, such dividend shall be deemed to be paid at the date of



                                       16
   25
declaration, and the subsequent payment of such dividend during such 60-day
period shall not be treated as an additional Restricted Payment. For purposes of
determining under clause (ii) above the amount expended for Restricted Payments,
cash distributed shall be valued at the face amount thereof and property other
than cash shall be valued at its fair market value as determined by the Board of
Directors as evidenced by a Board resolution.

    Notwithstanding the foregoing, the provisions of this Section 4.05 will not
prevent: (i) the purchase of Securities by the Company; (ii) the payment of any
dividend within 60 days after the date of declaration when the payment complied
with the foregoing provisions on the date of declaration; (iii) the purchase,
redemption or any acquisition or retirement for value of the Preferred Stock;
(iv) the retirement of any shares of the Company's capital stock by exchange
for, or out of the proceeds of the substantially concurrent sale (other than to
a subsidiary) of, other shares of its capital stock (other than any Disqualified
Stock), and neither such retirement nor the proceeds of any such sale or
exchange, to the extent used for such retirement, shall be included in any
computation made under this Section 4.05; and (v) the purchase 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.

SECTION 4.06.     CONTINUED EXISTENCE.

    Subject to Article 5, the Company will do or cause to be done all things
necessary to preserve and keep in full force and effect its existence as a
corporation and will refrain from taking any action that would cause its
existence as a corporation to cease, including without limitation any action
that would result in its liquidation, winding up or dissolution.

SECTION 4.07.     TAXES.

    The Company shall, and shall cause each of its Material Subsidiaries to, pay
prior to delinquency all taxes, assessments and governmental levies, except as
contested in good faith and by appropriate proceedings or where the failure to
do so would not have a material adverse effect on the Company and its
subsidiaries, taken as a whole.

SECTION 4.08.     MAINTENANCE OF PROPERTIES.

    The Company shall, and shall cause each of its subsidiaries to, take
reasonable action to maintain in appropriate condition each of its principal
properties which in the judgment of management is essential to the business
operations of the Company and its subsidiaries, taken as a whole, and the loss
of which would have a material adverse effect on the financial condition of the
Company and its subsidiaries, taken as a whole. Nothing contained in this
Section 4.08 shall prevent or restrict the sale, abandonment



                                       17
   26
or other disposition of any property which management shall deem advisable.

SECTION 4.09.     INSURANCE.

    The Company shall, and shall cause each of its subsidiaries to, take
reasonable action to maintain insurance, with financially sound and reputable
insurers, to the extent and against such hazards as may be deemed appropriate by
management (giving effect to self-insurance), on each of its principal
properties the loss of which, in the judgment of management, would have a
material adverse effect on the financial condition of the Company and its
subsidiaries, taken as a whole.

SECTION 4.10.     INVESTMENT COMPANY ACT.

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

SECTION 4.11.     CHANGE OF CONTROL.

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

    Within 30 days after any Change of Control, the Company (with notice to the
Trustee), or the Trustee upon reasonable notice and at the Company's request
(and at the expense of the Company), will mail or cause to be mailed to all
Holders on the date of the Change of Control a notice of the occurrence of such
Change of Control and of the Holders' rights arising as a result thereof. Such
notice will contain all instructions and materials necessary to enable Holders
to tender their Securities to the Company. Such notice, which shall govern the
terms of the Change of Control Offer, shall state:


                                       18
   27
               (1) that the Change of Control Offer is being made pursuant to
        this Section 4.11 and the length of time the Change of Control Offer
        will remain open;

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

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

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

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

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

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

    On or before a Change of Control Payment Date, the Company shall, to the
extent lawful, (i) if the Company appoints a depositary or Paying Agent, deposit
with such depositary or Paying Agent money sufficient to pay the purchase price
of all Securities tendered, (ii) deliver or cause the depositary or Paying Agent
to deliver to the Trustee Securities so tendered and (iii) deliver an Officers'
Certificate identifying the Securities accepted for payment by the Company in
accordance with the terms of this Section 4.11. The depositary, the Paying Agent
or the Company, as the case may be, shall promptly mail or deliver to each
tendering Holder an amount equal to the purchase price of the Securities
tendered by such Holder and accepted by the Company for purchase. The Company
will publicly announce the



                                       19
   28
results of the Change of Control Offer on the Change of Control Payment Date.
Any Change of Control Offer will be conducted in compliance with applicable
tender offer rules, including Section 14(e) of the Exchange Act and Rule 14e-1
thereunder.*

SECTION 4.12.     LIMITATION IN RANKING OF FUTURE INDEBTEDNESS.

terms of the instrument creating such Indebtedness in right of payment to any
Senior Indebtedness of the Company and which is not expressly by the terms of
the instrument creating such Indebtedness made pari passu with, or subordinate
and junior in right of payment to, the Securities.

    Upon any consolidation or merger, or any sale, lease, conveyance or other
disposition of all or substantially all of the assets of the Company in
accordance with Section 5.01, the successor entity formed by such consolidation
or into or with which the Company is merged or to which such sale, lease,
conveyance or other disposition is made shall succeed to, and be substituted
for, and may exercise every right and power of, the Company under this Indenture
with the same effect as if such successor entity had been named as the Company
herein; provided, however, that the predecessor Company in the case of a sale,
lease, conveyance or other disposition shall not be released from the obligation
to pay the principal of and interest on the Securities.

SECTION 5.03.     PURCHASE OPTION ON CHANGE OF CONTROL.

    This Article 5 does not affect the obligations of the Company (including
without limitation any successor to the Company) under this Indenture.

                           DEFAULTS AND REMEDIES

SECTION 6.01.     EVENTS OF DEFAULT.

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

               (1) the Company defaults in the payment of interest on any
        Security when the same becomes due and payable and the Default continues
        for a period of 30 days;

               (2) the Company defaults in the payment of the principal of and

   30
               (4) an event of default occurs under any mortgage, indenture or
        instrument under which there may be issued or by which there may be
        secured or evidenced any Indebtedness for money borrowed by the Company
        or any Material Subsidiary (or the payment of which is guaranteed by the
        Company or a Material Subsidiary), whether such Indebtedness or
        guarantee now exists or shall be created hereafter, other than
        Indebtedness which is or will be non-recourse to the Company or a
        Material Subsidiary, if (a) either (i) such event of default results
        from the failure to pay any such Indebtedness at maturity or (ii) as a
        result of such event of default the maturity of such Indebtedness has
        been accelerated prior to its expressed maturity and (b) the principal
        amount of such Indebtedness, together with the principal amount of any
        other such Indebtedness in default for failure to pay principal at
        maturity or the maturity of which has been so accelerated, aggregates
        [$_______] [the amount set forth in a supplemental indenture] or more;
        provided, however, that if such event of default shall be remedied,
        cured or waived, then the Event of Default hereunder by reason of such
        event of default shall be deemed likewise to have been remedied, cured
        or waived without further action by the Trustee or any of the
        Securityholders; or

               (5) a final judgment or final judgments for the payment of money
        are entered by a court or courts of competent jurisdiction against the
        Company or any Material Subsidiary which remains undischarged for a
        period (during which execution shall not be effectively stayed) of 60
        days, provided that the aggregate of all such judgments exceeds
        [$__________] [the amount set forth in a supplemental indenture];

        to or within the meaning of any Bankruptcy Law:

                      (A)  commences a voluntary case,

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

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

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

   31
               (7) a court of competent jurisdiction enters a judgment, order or
        decree under any Bankruptcy Law that:

                      (A)  is  for relief  against  the  Company or any
               Material Subsidiary in an involuntary case,

                      (B)  appoints  a Custodian  of the Company or any

               any Material Subsidiary,

        and the order or decree  remains  unstayed and in effect for 60
        days.

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

    A Default under clause (3) (other than Defaults under Section 4.05, 4.06[,
or] 5.01 [or, with respect to the right to convert Securities, Article XII],
which Defaults shall be Events of Default with the notice but without the
passage of time specified in this paragraph), (4) or (5) is not an Event of
Default until the Trustee or the Holders of at least 25% in principal amount of
the then outstanding Securities notify the Company of the Default and the
Company does not cure the Default within 60 days after receipt of the notice.
The notice must specify the Default, demand that it be remedied and state that
the notice is a "Notice of Default."

SECTION 6.02.     ACCELERATION.

    If an Event of Default (other than an Event of Default specified in clauses
(6) and (7) of Section 6.01) occurs and is continuing, the Trustee by notice to
the Company, or the Holders of at least 25% in principal amount of the then
outstanding Securities by notice to the Company and the Trustee, may declare the
unpaid principal of and accrued interest on all the Securities to be due and
payable. Upon such declaration the principal and interest shall be due and
payable immediately. If an Event of Default specified in clause (6) or (7) of
Section 6.01 occurs, such an amount shall ipso facto become and be immediately
due and payable without any declaration or other act on the part of the Trustee
or any Holder. The Holders of a majority in principal amount of the then
outstanding Securities by notice to the Trustee may rescind an acceleration and
its consequences, except nonpayment of principal or interest on the Securities,
if the rescission would not conflict with any judgment or decree.

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

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

SECTION 6.04.     WAIVER OF PAST DEFAULTS.

    The Holders of a majority in principal amount of the then outstanding
Securities by notice to the Trustee may waive an existing Default or Event of
Default and its consequences except a continuing Default or Event of Default in
the payment of the principal of or interest on any Security. When a Default is
waived, it is cured and stops continuing.

SECTION 6.05.     CONTROL BY MAJORITY.

    The Holders of a majority in principal amount of the then outstanding
Securities may direct the time, method and place of conducting any proceeding
for any remedy available to the Trustee or exercising any trust or power
conferred on it. However, the Trustee may refuse to follow any direction that
conflicts with law or this Indenture, is unduly prejudicial to the rights of
other Securityholders or would involve the Trustee in personal liability.

SECTION 6.06.     LIMITATION ON SUITS.

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

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

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

                                       24
   33
               (3)  such   Holder  or  Holders  offer  to  the  Trustee
        indemnity   satisfactory  to  the  Trustee  against  any  loss,
        liability or expense;

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

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

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

SECTION 6.07.     RIGHTS OF HOLDERS TO RECEIVE PAYMENT [AND TO CONVERT
                  SECURITIES].

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

SECTION 6.08.     COLLECTION SUIT BY TRUSTEE.

    If an Event of Default specified in Section 6.01(1) or (2) occurs and is
continuing, the Trustee may recover judgment in its own name and as trustee of
an express trust against the Company for the whole amount of principal and
interest remaining unpaid on the Securities and interest on overdue principal
and interest and such further amount as shall be sufficient to cover the costs
and, to the extent lawful, expenses of collection, including the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel.

SECTION 6.09.     TRUSTEE MAY FILE PROOFS OF CLAIM.

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



                                       25
   34
arrangement, adjustment or composition affecting the Securities or the rights of
any Holder thereof, or to authorize the Trustee to vote in respect of the claim
of any Securityholder in any such proceeding.

SECTION 6.10.     PRIORITIES.

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

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

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

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

        Fourth:   to the Company.

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

SECTION 6.11.     UNDERTAKING FOR COSTS.

    In any suit for the enforcement of any right or remedy under this Indenture
or in any suit against the Trustee for any action taken or omitted by it as a
Trustee, a court in its discretion may require the filing by any party litigant
in the suit of an undertaking to pay the costs of the suit, and the court in its
discretion may assess reasonable costs, including reasonable attorneys fees,
against any party litigant in the suit, having due regard to the merits and good
faith of the claims or defenses made by the party litigant. This Section does
not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07
or a suit by Holders of more than 10% in principal amount of the then
outstanding Securities.

                                 ARTICLE 7
                                THE TRUSTEE

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

   35
SECTION 7.01.     DUTIES OF THE TRUSTEE.

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

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

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

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

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

               (1)  This   paragraph  does  not  limit  the  effect  of
        paragraph (b) of this Section;

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

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

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

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

                                       27
   36
    (f) The Trustee shall not be liable for interest on any money received by it
except as the Trustee may agree in writing with the Company. Money held in trust
by the Trustee need not be segregated from other funds except to the extent
required by law.

SECTION 7.02.     RIGHTS OF THE TRUSTEE.

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

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

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

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

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

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

SECTION 7.03.     INDIVIDUAL RIGHTS OF THE TRUSTEE.

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

                                       28
   37
SECTION 7.04.     TRUSTEE'S DISCLAIMER.

    The Trustee makes no representation as to the validity or adequacy of this
Indenture or the Securities, it shall not be accountable for the Company's use
of the proceeds from the Securities and it shall not be responsible for any
statement in the Indenture or any statement in the Securities other than its
authentication.

SECTION 7.05.     NOTICE OF DEFAULTS.

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

SECTION 7.06.     REPORTS BY THE TRUSTEE TO HOLDERS.

    Within 60 days after the reporting date stated in Section 10.10, the Trustee
shall mail to Securityholders a brief report dated as of such reporting date
that complies with TIA Section 313(a), if such report is required by TIA Section
313(a). The Trustee also shall comply with TIA Section 313(b)(2). The Trustee
shall also transmit by mail all reports as required by TIA Section 313(c).

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

SECTION 7.07.     COMPENSATION AND INDEMNITY.

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

    The Company shall indemnify each of the Trustee and any successor Trustee
against any loss, damage, claims, liability or out-of-pocket expenses, including
taxes (other than taxes based on the income, revenues or receipts of the
Trustee) incurred by it in connection with the acceptance (with respect to legal
fees and other out-of-pocket expenses of the Trustee



                                       29
   38
in connection with the acceptance of the trust or trusts hereunder, to the
extent provided in the writing provided for in this Section 7.07) or
administration of the trust or trusts hereunder, except as set forth in the next
paragraph. The Trustee shall notify the Company promptly of any claim for which
it may seek indemnity. The Company shall defend the claim with counsel, who may
be outside counsel to the Company but shall in all events be reasonably
satisfactory to the Trustee, and the Trustee shall cooperate in the defense. In
addition, if the Company does not so defend the Trustee or if at any time the
counsel so selected is ethically prohibited from representing the Trustee
(whether because of a conflict of interest or the provisions of the TIA), then
the Trustee may retain one separate counsel and the Company shall pay the
reasonable fees and expenses of such separate counsel. The indemnification
herein extends to any settlement, provided that the Company will not be liable
for any settlement made without its consent, provided further that such consent
will not be unreasonably withheld.

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

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

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

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

SECTION 7.08.     REPLACEMENT OF THE TRUSTEE.

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

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

                                       30
   39
               (1)  the Trustee fails to comply with Section 7.10;

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

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

               (4)  the Trustee becomes incapable of acting.

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

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

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

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

SECTION 7.09.     SUCCESSOR TRUSTEE BY MERGER, ETC.

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

SECTION 7.10.     ELIGIBILITY; DISQUALIFICATION.

    This Indenture shall always have a Trustee who satisfies the requirements of
TIA Section 310(a)(1). The Trustee shall always have a combined capital and
surplus as stated in Section 10.10. The Trustee is subject to TIA Section
310(b), including the optional provision permitted by the second sentence of TIA
Section 310(b)(9).

SECTION 7.11.     PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

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

                                 ARTICLE 8
                  SATISFACTION AND DISCHARGE OF INDENTURE

SECTION 8.01.     TERMINATION OF COMPANY'S OBLIGATIONS.

    (a) This Indenture shall cease to be of further effect (except that the
Company's obligations under Section 7.07 and 8.03 shall survive) when all
outstanding Securities theretofore authenticated and issued have been delivered
(other than destroyed, lost or stolen Securities that have been replaced or
paid) to the Trustee for cancellation and the Company has paid all sums payable
hereunder. In addition, the Company may elect to have either paragraph (b) or
paragraph (c) below be applied to the outstanding Securities upon compliance
with the conditions set forth in paragraph (d).

    (b) Upon the Company's exercise under paragraph (a) of the option applicable
to this paragraph (b), the Company shall be deemed to have been released and
discharged from its obligations with respect to the outstanding Securities on
the date the conditions set forth below are satisfied ("legal defeasance"). For
this purpose, legal defeasance means that the Company shall be deemed to have
paid and discharged the entire indebtedness represented by the outstanding
Securities, which shall thereafter be deemed to be "outstanding" only for the
purposes of the Sections of and matters under this Indenture referred to in (i)
and (ii) below, and to have satisfied all its other obligations under such
Securities and this Indenture insofar as such Securities are concerned (and the
Trustee, at the expense of the Company, shall execute proper instruments
acknowledging the same), except for the following, which shall survive until
otherwise terminated or discharged hereunder: (i) the rights of Holders of
outstanding Securities to receive solely from the trust fund described in
paragraph (d) below and as more fully set forth in such paragraph, payments in
respect of the principal of,



                                       32
   41
premium, if any, and interest on such Securities when such payments are due,
(ii) the Company's obligations with respect to such Securities under Sections
2.06, 2.07 and 4.04, and, with respect to the Trustee, under Section 7.07, (iii)
the rights, powers, trusts, duties and immunities of the Trustee hereunder and
(iv) this Section 8.01. Subject to compliance with this Section 8.01, the
Company may exercise its option under this paragraph (b) notwithstanding the
prior exercise of its option under paragraph (c) below with respect to the
Securities.

    (c) Upon the Company's exercise under paragraph (a) of the option applicable
to this paragraph (c), the Company shall be released and discharged from its
obligations under any covenant contained in Article 5 and in Sections 4.02
through 4.12 with respect to the outstanding Securities on and after the date
the conditions set forth below are satisfied ("covenant defeasance"), and the
Securities shall thereafter be deemed to be not "outstanding" for the purpose of
any direction, waiver, consent or declaration or act of Holders (and the
consequences of any thereof) in connection with such covenants, but shall
continue to be deemed "outstanding" for all other purposes hereunder. For this
purpose, such covenant defeasance means that, with respect to the outstanding
Securities, the Company may omit to comply with and shall have no liability in
respect of any term, condition or limitation set forth in any such covenant,
whether directly or indirectly, by reason of any reference elsewhere herein to
any such covenant or by reason of any reference in any such covenant to any
other provision herein or in any other document and such omission to comply
shall not constitute a Default or an Event of Default under Section 6.01 but,
except as specified above, the remainder of this Indenture and such Securities
shall be unaffected thereby.

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

               (1) the Company has irrevocably deposited in trust with the
        Trustee or, at the option of the Trustee, with a trustee, satisfactory
        to the Trustee and the Company under the terms of an irrevocable trust
        agreement in form and substance satisfactory to the Trustee, money or
        United States Government Obligations (defined below in this Section
        8.01) sufficient to pay principal and interest on the Securities to
        maturity and all other sums payable by it hereunder; provided that (i)
        the trustee of the irrevocable trust shall have been irrevocably
        instructed to pay such money or the proceeds of such United States
        Government Obligations to the Trustee and (ii) the Trustee shall have
        been irrevocably instructed to apply such money or the proceeds of such
        United States Government Obligations to the payment of said principal
        and interest with respect to the Securities;

                                       33
   42
               (2) the Company has delivered to the Trustee an Officers'
        Certificate stating that (A) all conditions precedent provided for
        relating to either the legal defeasance under paragraph (b) above or the
        covenant defeasance under paragraph (c) above, as the case may be, have
        been complied with and (B) if any other Indebtedness of the Company
        shall then be outstanding or committed, such legal defeasance or
        covenant defeasance will not violate the provisions of the agreements or
        instruments evidencing such Indebtedness;

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

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

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

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

    After such irrevocable deposit made pursuant to this Section 8.01 and
satisfaction of the other conditions set forth herein, the Trustee upon request


                                       34
   43
shall acknowledge in writing the discharge of the Company's obligations under
this Indenture except for those surviving obligations specified above.

    As used herein, "United States Government Obligations" means direct
obligations of the United States of America for the payment of which the full
faith and credit of the United States of America is pledged. In order to have
money available on a payment date to pay principal or interest on the
Securities, the United States Government Obligations shall be payable as to
principal or interest on or before such payment date in such amounts as will
provide the necessary money. United States Government Obligations shall not be
callable at the issuer's option.

SECTION 8.02.     APPLICATION OF TRUST MONEY.

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

SECTION 8.03.     REPAYMENT TO COMPANY.

    Subject to Section 8.01(d), the Trustee and the Paying Agent shall promptly
pay to the Company upon written request any excess money or securities held by
them at any time.

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

SECTION 8.04.     REINSTATEMENT.

    If (i) the Trustee or Paying Agent is unable to apply any money in
accordance with Section 8.02 by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application and (ii) the Holders of at least a majority in principal amount of
the then outstanding Securities so request by written notice to the Trustee, the
Company's obligations under this Indenture and the Securities shall be revived
and reinstated as though no deposit had



                                       35
   44
occurred pursuant to Section 8.01 until such time as the Trustee or Paying Agent
is permitted to apply all such money in accordance with Section 8.02; provided,
however, that if the Company makes any payment of interest on or principal of
any Security following the reinstatement of its obligations, the Company shall
be subrogated to the rights of the Holders of such Securities to receive such
payment from the money held by the Trustee or Paying Agent.

                                 ARTICLE 9
                                AMENDMENTS

SECTION 9.01.     WITHOUT THE CONSENT OF HOLDERS.

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

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

               (2)  to comply with Section[s] 5.01 [and 12.18];

               (3)  to   provide  for   uncertificated   Securities  in
        addition to certificated Securities;

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

               (5) to add to the covenants of the Company such further
        covenants, restrictions, conditions or provisions as the Company and the
        Trustee shall consider to be for the protection of the Securityholders,
        and to make the occurrence, or the occurrence and continuance, of a
        default in any such additional covenants, restrictions, conditions or
        provisions an Event of Default permitting the enforcement of all or any
        of the several remedies provided in this Indenture as herein set forth;
        provided that in respect of any such additional covenant, restriction,
        condition or provision, such supplemental indenture may provide for a
        particular period of grace after default (which period may be shorter or
        longer than that allowed in the case of other defaults) or may provide
        for an immediate enforcement upon such an Event of Default or may limit
        the remedies available to the Trustee upon such an Event of Default or
        may limit the right of the Securityholders to waive such an Event of
        Default;

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

                                       36
   45
               (7) to modify, eliminate or add to the provisions of this
        Indenture to such extent as shall be necessary to effect the
        qualification of the Indenture under the TIA, or under any similar
        federal statute hereafter enacted; or

               (8) before any Securities are issued, to make any other change in
        this Indenture not prohibited by the TIA.

SECTION 9.02.     WITH THE CONSENT OF HOLDERS.

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

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

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

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

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

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

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

               (5)  make  any  change  in  Section  6.04,  6.07 or 9.02
        (this sentence); [or]

               (6)  waive  a default in the  payment  of the  principal
        of, or interest on, any Security [or any default  under Article
        12; or]

               (7)  make  any change that  adversely  affects the right
        to convert any Security].

    To secure a consent of the Holders under this Section, it shall not be
necessary for the Holders to approve the particular form of any proposed


                                       37
   46
amendment or waiver, but it shall be sufficient if such consent approves the
substance thereof.

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

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

SECTION 9.03.     COMPLIANCE WITH THE TRUST INDENTURE ACT.

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

SECTION 9.04.     REVOCATION AND EFFECT OF CONSENTS.

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

    The Company may, but shall not be obligated to, fix a record date for the
purpose of determining the Holders entitled to consent to any amendment or
waiver. If a record date is fixed, then notwithstanding the provisions of the
immediately preceding paragraph, those persons who were Holders at such record
date (or their duly designated proxies), and only those persons, shall be
entitled to consent to such amendment or waiver or to revoke any consent
previously given, whether or not such persons continue to be Holders after such
record date. No consent shall be valid or effective for more than 90 days after
such record date unless consents from Holders of the principal amount of
Securities required hereunder for such amendment or waiver to be effective shall
have also been given and not revoked within such 90-day period.

    After an amendment or waiver becomes effective it shall bind every
Securityholder, unless it is of the type described in any of clauses (1)



                                       38
   47
through (7) of Section 9.02. In such case, the amendment or waiver shall bind
each Holder of a Security who has consented to it.

SECTION 9.05.     NOTATION ON OR EXCHANGE OF SECURITIES.

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

SECTION 9.06.     THE TRUSTEE PROTECTED.

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

                                ARTICLE 10
                            GENERAL PROVISIONS

SECTION 10.01.    TRUST INDENTURE ACT CONTROLS.

    If any provision of this Indenture limits, qualifies or conflicts with
another provision which is required to be included in this Indenture by the TIA
as in effect at the date hereof or, to the extent required by law, as amended
after the date hereof, the required provision shall control.

SECTION 10.02.    NOTICES.

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

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

                                       39
   48
    If a notice or communication is mailed in the manner provided above within
the time prescribed, it is duly given, whether or not the addressee receives it.

    If the Company mails a notice or communication to Securityholders, it shall
mail a copy to the Trustee and each Agent at the same time.

    All other notices or communications shall be in writing.

SECTION 10.03.    COMMUNICATION BY HOLDERS WITH OTHER HOLDERS.

    Securityholders may communicate pursuant to TIA Section 312(b) with other
Securityholders with respect to their rights under this Indenture or the
Securities. The Company, the Trustee, the Registrar and anyone else shall have
the protection of TIA Section 312(c).

SECTION 10.04.    CERTIFICATE AND OPINION AS TO CONDITIONS PRECEDENT.

    Upon any request or application by the Company to the Trustee to take any
action under this Indenture, the Company shall furnish to the Trustee:

               (1) an Officers' Certificate stating that, in the opinion of the
        Company, all conditions precedent, if any, provided for in this
        Indenture relating to the proposed action have been complied with; and

               (2) an Opinion of Counsel stating that, in the opinion of such
        counsel, all such conditions precedent have been complied with.

SECTION 10.05.    STATEMENTS REQUIRED IN CERTIFICATE OR OPINION.

    Each certificate or opinion with respect to compliance with a condition or
covenant provided for in this Indenture shall include:

               (1)  a   statement   that   the   person   making   such
        certificate or opinion has read such covenant or condition;

               (2) a brief statement as to the nature and scope of the
        examination or investigation upon which the statements or opinions
        contained in such certificate or opinion are based;

               (3) a statement that, in the opinion of the Company, such person
        has made such examination or investigation as is necessary to enable him
        or her to express an informed opinion as



                                       40
   49
        to whether or not such covenant or condition has been complied with; and

               (4)  a  statement  as to whether or not,  in the opinion
        of the Company,  such  condition or covenant has been  complied
        with;

provided, however, that with respect to matters of fact an Opinion of Counsel
may rely on an Officers' Certificate.

SECTION 10.06.    RULES BY TRUSTEE AND AGENTS.

    The Trustee may make reasonable rules for action by or a meeting of
Securityholders. The Registrar [, or] Paying Agent [or Conversion Agent] may
make reasonable rules and set reasonable requirements for its functions.

SECTION 10.07.    LEGAL HOLIDAYS; BUSINESS DAYS.

    A "Legal Holiday" is a Saturday, a Sunday or a day on which banking
institutions in the City of New York or in the city in which the principal
office of the Trustee is located are not required to be open, and a "Business
Day" is any day that is not a Legal Holiday. If a payment date is a Legal
Holiday at a place of payment, payment may be made at that place on the next
succeeding day that is not a Legal Holiday, and no interest shall accrue for the
intervening period.

SECTION 10.08.    NO RECOURSE AGAINST OTHERS.

    No director, officer, employee or shareholder, as such, of the Company shall
have any liability for any obligations of the Company under the Securities or
the Indenture or for any claim based on, in respect of or by reason of such
obligations or their creation. Each Securityholder by accepting a Security
waives and releases all such liability. The waiver and release are part of the
consideration for the Securities.

    This Indenture may be executed in any number of counterparts and by the

                               SUBORDINATION

SECTION 11.01.    AGREEMENT TO SUBORDINATE.

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


                                       43
   52
SECTION 11.02.    CERTAIN DEFINITIONS.

    "Indebtedness" of any person, means any indebtedness, 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 which arise as a result of claims under or drawings
pursuant to surety, performance, completion or maintenance bonds.

    "Representative" means the indenture trustee or other trustee, agent or
representative for an issue of Senior Indebtedness.

    "Senior Indebtedness" means all Indebtedness (present or future) created,
incurred, assumed or 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 Securities. Notwithstanding
anything to the contrary in the foregoing, Senior Indebtedness shall not include
(i) any Indebtedness of the Company to any of its subsidiaries, (ii) any trade
payables of the Company or (iii) guarantees by the Company of Indebtedness (a)
outstanding at the date hereof or (b) which may be outstanding in the future,
except that Senior Indebtedness shall include any guarantees as may be listed in
a supplemental indenture and any other present and future guarantees that
provide by their terms that they constitute Senior Indebtedness.

SECTION 11.03.    LIQUIDATION; DISSOLUTION; BANKRUPTCY.

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

               (1) holders of Senior Indebtedness shall be entitled to receive
        payment in full in cash of the principal of and interest (including
        interest accruing after the commencement of any such proceeding) to the
        date of payment on the Senior Indebtedness before Securityholders shall
        be entitled to receive any payment of principal of or interest on
        Securities; and

               (2) until the Senior Indebtedness is paid in full in cash, any
        distribution to which Securityholders would be entitled but for this
        Article shall be made to holders of Senior Indebtedness



                                       44
   53
        as their interests may appear, except that Securityholders may receive
        securities that are subordinated to Senior Indebtedness to at least the
        same extent as the Securities.

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

SECTION 11.04.    DEFAULT ON SENIOR INDEBTEDNESS.

    Upon the final maturity of any Senior Indebtedness by lapse of time,
acceleration or otherwise, all such Senior Indebtedness shall first be paid in
full, or such payment duly provided for in cash or in a manner satisfactory to
the holders of such Senior Indebtedness, before any payment is made by the
Company or any person acting on behalf of the Company on account of the
principal or interest of the Securities.

    The Company may not pay principal of or interest on the Securities and may
not acquire any Securities for cash or property (other than capital stock of the
Company or other securities of the Company that are subordinated to Senior
Indebtedness to at least the same extent as the Securities) if:

               (1) a default on Senior Indebtedness occurs and is continuing
        that permits holders of such Senior Indebtedness to accelerate its
        maturity, and

               (2) the default is the subject of judicial proceedings or the
        Company receives a notice of the default from a person who may give it
        pursuant to Section 11.12, provided that, if the Company receives any
        such notice, a subsequent notice received within nine months thereafter
        shall not be effective for purposes of this Section.

    The Company shall resume payments on the Securities and may acquire them
when:

               (a)  the default is cured or waived, or

               (b)  180  days  pass  after  the  notice is given if the
        default is not the subject of judicial proceedings,

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

SECTION 11.05.    ACCELERATION OF SECURITIES.

    If payment of the Securities is accelerated because of an Event of Default,
the Company shall promptly notify holders of Senior Indebtedness



                                       45
   54
of the acceleration. The Company shall pay the Securities when 180 days pass
after the acceleration occurs if this Article permits the payment at that time;
provided, however, that if no Senior Indebtedness is outstanding at the time of
such acceleration, the Company shall pay the Securities in accordance with the
provisions of Article 6.

SECTION 11.06.    WHEN DISTRIBUTIONS MUST BE PAID OVER.

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

    If a distribution is made to Securityholders that because of this Article
should not have been made to them, the Securityholders who receive the
distribution shall hold it in trust for holders of Senior Indebtedness and pay
it over to them as their interests may appear.

SECTION 11.07.    NOTICE BY THE COMPANY.

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

SECTION 11.08.    SUBROGATION.

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



                                       46
   55
between the Company and Securityholders, a payment by the Company on Senior
Indebtedness.

SECTION 11.09.    RELATIVE RIGHTS.

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

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

               (2)  affect the relative rights of  Securityholders  and
        creditors  of  the  Company,   other  than  holders  of  Senior
        Indebtedness; or

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

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

SECTION 11.10.    SUBORDINATION MAY NOT BE IMPAIRED BY THE COMPANY.

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

SECTION 11.11.    DISTRIBUTION OR NOTICE TO THE REPRESENTATIVE.

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

SECTION 11.12.    RIGHTS OF THE TRUSTEE AND PAYING AGENT.

    Notwithstanding any provision of this Article 11 or any other provision of
this Indenture, the Trustee and Paying Agent shall not at any time be charged
with knowledge of the existence of any facts which would prohibit the making of
any payment to or by the Trustee or a Paying Agent or the



                                       47
   56
taking of any other action (pursuant to this Article 11) by the Trustee or a
Paying Agent unless and until the Trustee or such Paying Agent, as the case may
be, shall have received at its office specified in Section 10.10 written notice
thereof from the Company, a Representative or a holder of Senior Indebtedness
and, prior to the receipt of any such written notice, the Trustee, subject to
the provisions of Sections 7.01 and 7.02, and such Paying Agent, shall be
entitled in all respects conclusively to assume that no such fact exists. The
Trustee or Paying Agent may continue to make payments on the Securities unless
it receives such a notice at least three business days prior to the date upon
which payment is due.

    The Trustee shall be entitled to reasonably rely in good faith on the
delivery to it of a written notice by a person representing himself, herself or
itself to be a Representative or a holder of Senior Indebtedness to establish
that such notice has been given by a Representative or a holder of such Senior
Indebtedness. Only the Company, a Representative or a holder of Senior
Indebtedness that has no Representative may give the notice.

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

    Upon any payment or distribution of assets of the Company referred to in
this Article 11, the Trustee and the Holders of the Securities shall be entitled
to rely upon any order or decree entered by any court of competent jurisdiction
in which such insolvency, bankruptcy, receivership, liquidation, reorganization,
dissolution, winding up or similar case or proceeding is pending, or a
certificate of the trustee in bankruptcy, liquidating trustee, Custodian,
receiver, assignee for the benefit of creditors, agent or other person making
such payment or distribution, delivered to the Trustee or to the Holders of
Securities, for the purpose of ascertaining the persons entitled to participate
in such payment or distribution, the holders of Senior Indebtedness and other
indebtedness of the Company, the amount thereof or payable thereon, the amount
or amounts paid or distributed thereon and all other facts pertinent thereto or
to this Article 11.

                                       48
   57
    The Trustee in its individual or any other capacity may hold Senior
Indebtedness with the same rights it would have if it were not Trustee.
Any Agent may do the same with like rights.

SECTION 11.13     NO FIDUCIARY DUTY TO HOLDERS OF SENIOR INDEBTEDNESS.

    With respect to the holders of Senior Indebtedness, the Trustee undertakes
to perform or to observe only such of its covenants and obligations as are
specifically set forth in this Article 11, and no implied covenants or
obligations with respect to the holders of Senior Indebtedness shall be read
into this Indenture against the Trustee or Paying Agent. Neither the Trustee nor
the Paying Agent shall be deemed to owe any fiduciary duty to the holders of
such Senior Indebtedness and, subject to the provisions of Section 7.02, the
Trustee shall not be liable to any holder of such Senior Indebtedness if it
shall, in the absence of bad faith, pay over or deliver to holders of
Securities, the Company or any other person monies or assets to which any holder
of such Senior Indebtedness shall be entitled by virtue of this Article 11 or
otherwise.

                                [ARTICLE 12
                                CONVERSION

SECTION 12.01.    CONVERSION PRIVILEGE.

    For the purpose of this Article XII and paragraph 17 of the Securities,
["Common Stock" means the common stock of the Company as it exists on the date
of this Indenture or as it may be constituted from time to time.] [and]
["Preferred Stock" means the Series __ Preferred Stock of the Company].

    A Holder of a Security may convert it into [Preferred] [Common] Stock at any
time during the period stated in paragraph 17 of the Securities. The number of
shares issuable upon conversion of a Security is determined as follows: (i)
divide the principal amount to be converted by the conversion price in effect on
the conversion date; then (ii) round the result to the nearest 1/100th of a
share.

    The initial conversion price is stated in paragraph 17 of the Securities.
The conversion price is subject to adjustment.

    A Holder may convert a portion of a Security if the portion is $1,000 or an
integral multiple of $1,000. Provisions of this Indenture that apply to
conversion of all of a Security also apply to conversion of a portion of it.

                                       49
   58
SECTION 12.02.    CONVERSION PROCEDURE.

    To convert a Security a Holder must satisfy the requirements in paragraph 17
of the Securities. The date on which the Holder satisfies all those requirements
is the conversion date. As soon as practical, the Company shall deliver through
the Conversion Agent a certificate for the number of full shares of [Preferred]
[Common] Stock issuable upon the conversion and a check for any fractional
share. The person in whose name the certificate is registered shall be treated
as a stockholder of record on and after the conversion date.

    No payment or adjustment will be made for accrued interest on a converted
Security or dividends on any [Preferred] [Common] Stock issued. However,
interest will be paid on any interest payment date with respect to Securities
surrendered for conversion after a record date for the payment of interest to
the registered Holder on such record date.

    If a Holder converts more than one Security at the same time, the number of
full shares issuable upon the conversion shall be based on the total principal
amount of the Securities converted.

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

    If the last day on which a Security may be converted is a Legal Holiday in a
place where a Conversion Agent is located, the Security may be surrendered to
that Conversion Agent on the next succeeding day that is not a Legal Holiday.

SECTION 12.03.    FRACTIONAL SHARES.

    The Company will not issue a fractional share of [Preferred] [Common] Stock
upon conversion of a Security. Instead the Company will deliver its check for
the current market value of the fractional share. The current market value of a
fraction of a share is determined as follows: (i) multiply the current market
price of a full share by the fraction; then (ii) round the result to the nearest
cent.

    The current market price of a share of [Preferred] [Common] Stock is the
Quoted Price of the [Preferred] [Common] Stock on the last trading day prior to
the conversion date. As used in Sections 12.03 and 12.11, the "Quoted Price" of
the Common Stock is the last reported sales price of the [Preferred] [Common]
Stock on the New York Stock Exchange or such other securities exchange on which
the [Preferred] [Common] Stock may



                                       50
   59
then be listed, or if the Common Stock is not listed on a securities exchange,
the last reported sales price of the [Preferred] [Common] Stock as reported by
NASDAQ, National Market System or if neither so reported or listed, the last
reported bid price of the [Preferred] [Common] Stock. In the absence of such a
quotation, the Company shall determine the current market price on the basis of
such quotations or other information as it considers appropriate.

SECTION 12.04.    TAXES ON CONVERSION.

    If a Holder of a Security converts it, the Company shall pay any
documentary, stamp or similar issue or transfer tax due on the issue of shares
of [Preferred] [Common] Stock upon the conversion. However, the Holder shall pay
any such tax which is due because the shares are issued in a name other than the
Holder's name.

SECTION 12.05.    COMPANY TO PROVIDE STOCK.

    The Company has reserved and shall continue to reserve out of its authorized
but unissued [Preferred] [Common] Stock or its [Preferred] [Common] Stock held
in treasury enough shares of [Preferred] [Common] Stock to permit the conversion
of the Securities in full.

    All shares of [Preferred] [Common] Stock which may be issued upon conversion
of the Securities shall be fully paid and non-assessable.

    The Company will endeavor to comply with all securities laws regulating the
offer and delivery of shares of [Preferred] [Common] Stock upon conversion of
Securities and will endeavor to list such shares on each national securities
exchange on which the [Preferred] [Common] Stock is listed.

SECTION 12.06.    ADJUSTMENT FOR CHANGE IN CAPITAL STOCK.

    Subject to Section 12.18, if the Company:

               (1) pays a dividend or makes a distribution on its [Preferred]
        [Common] Stock in shares of its [Preferred] [Common] Stock;

               (2) subdivides its outstanding shares of [Preferred] [Common]
        Stock into a greater number of shares;

               (3) combines its outstanding shares of [Preferred] [Common] Stock
        into a smaller number of shares;



                                       51
   60
               (4) makes a distribution on its [Preferred] [Common] Stock in
        shares of its capital stock other than [Preferred] [Common] Stock; or

               (5) issues by reclassification of its [Preferred] [Common] Stock
        any shares of its capital stock;

then the conversion privilege and the conversion price in effect immediately
prior to such action shall be adjusted so that the Holder of a Security
thereafter converted may receive the number of shares of capital stock of the
Company which he would have owned immediately following such action if he had
converted the Security immediately prior to such action.

    The adjustment shall become effective immediately after the record date in
the case of a dividend or distribution and immediately after the effective date
in the case of a subdivision, combination or reclassification.

    If after an adjustment a Holder of a Security upon conversion of it may
receive shares of two or more classes of capital stock of the Company, the
Company shall determine the allocation of the adjusted conversion price between
the classes of capital stock. After such allocation, the conversion privilege
and the conversion price of each class of capital stock shall thereafter be
subject to adjustment on terms comparable to those applicable to [Preferred]
[Common] Stock in this Article.

SECTION 12.07.    ADJUSTMENT FOR RIGHTS ISSUE.

    If the Company distributes any rights or warrants [other than the Warrants
(the "Warrants") which are issued as part of unit consisting of Warrants and the
Securities] to all holders of its [Preferred] [Common] Stock entitling them for
a period expiring within 60 days after the record date mentioned below to
purchase shares of [Preferred] [Common] Stock at a price per share less than the
current market price per share on that record date, the conversion price shall
be adjusted in accordance with the formula set forth below and the paragraph
following such formula:


                                                      N  x P
                                                      ------
                           C'  =  C    x   O   +         M
                                           ------------------
                                             O    +      N

where:

        C' = the adjusted conversion price.

        C = the current conversion price.



                                       52
   61
        O      = the number of shares of [Preferred] [Common] Stock outstanding
                 on the record date.

        N      = the number of additional shares of [Preferred] [Common] Stock
                 offered.

        P      = the offering price per share of the additional shares.

        M      = the current market price per share of [Preferred] [Common]
                 Stock on the record date.

    The adjustment shall be made successively whenever any such rights become
exercisable or such warrants are issued and shall become effective immediately
after the rights become exercisable or after the record date for the
determination of stockholders entitled to receive the warrants. If at the end of
the period during which such warrants or rights are exercisable, not all
warrants or rights shall have been exercised, the conversion price shall be
immediately readjusted to what it would have been if "N" in the above formula
had been the number of shares actually issued.

SECTION 12.08.    ADJUSTMENT FOR OTHER DISTRIBUTIONS.

    If the Company distributes to all holders of its [Preferred] [Common] Stock
(as such) any of its assets or debt securities or any rights or warrants to
purchase assets, debt securities or other securities of the Company, the
conversion price shall be adjusted in accordance with the formula set forth
below and the paragraph following such formula:



                          C'  =  C    x    M - F
                                           -----
                                             M

where:

        C'     = the adjusted conversion price.

        C      = the current conversion price.

        M      = the current market price per share of [Preferred] [Common]
                 Stock on the record date mentioned below.

        F      = the fair market value on the record date of the assets,
                 securities, rights or warrants applicable to one share of
                 [Preferred] [Common] Stock. The Board of Directors shall
                 determine the fair market value.



                                       53
   62
    The adjustment shall be made successively whenever any such rights become
exercisable or any such distribution (other than of such rights) is made and
shall become effective immediately after any such rights become exercisable (as
to rights) or after the record date for the determination of stockholders
entitled to receive the distribution (as to other distributions).
Notwithstanding the foregoing, no adjustment shall be made in the event that
rights become exercisable if and to the extent Holders of Securities have
received or are entitled to receive such rights upon conversion. In addition, to
the extent the rights or warrants expire unexercised, then the conversion price
shall be promptly readjusted to the conversion price which would then be in
effect had the adjustment been made based on the number of rights or warrants
exercised.

    This Section does not apply to regular cash dividends or cash distributions
paid out of consolidated current earnings as shown on the books of the Company.
Also, this Section does not apply to rights or warrants referred to in Section
12.07, including the Warrants.

SECTION 12.09.    ADJUSTMENT FOR [PREFERRED] [COMMON] STOCK ISSUE.

    If the Company issues shares of [Preferred] [Common] Stock for a
consideration per share less than the current market price per share on the date
the Company fixes the offering price of such additional shares, the conversion
price shall be adjusted in accordance with the formula:

                                        O + P
                                           ---
                                            M
                              C' = C  x -------
                                          A

where:

        C'     = the adjusted conversion price.

        C      = the then current conversion price.

        O      = the number of shares outstanding immediately prior to the
                 issuance of such additional shares.

        P      = the aggregate consideration received for the issuance of such
                 additional shares.

        M      = the current market price per share on the date of issuance of
                 such additional shares.

        A      = the number of shares outstanding immediately after the issuance
                 of such additional shares.


                                       54
   63
    The adjustment shall be made successively whenever any such issuance is
made, and shall become effective immediately after such issuance.

    This Section does not apply to (i) any of the transactions described in
Sections 12.07, 12.08 and 12.10, (ii) the conversion of Securities, or the
conversion, exchange or exercise of other securities convertible or exchangeable
for [Preferred] [Common] Stock, (iii) [Preferred] [Common] Stock issued to the
Company's employees under bona fide employee plans adopted by the Board of
Directors and approved by the holders of [Preferred] [Common] Stock when
required by law, if such [Preferred] [Common] Stock would otherwise be covered
by this Section (but only to the extent that the aggregate number of shares
excluded hereby and issued after the date of this Indenture shall not exceed
[5%] of the [Preferred] [Common] Stock outstanding at the time of the adoption
of each such plan, exclusive of antidilution adjustments thereunder), (iv)
[Preferred] [Common] Stock issued to acquire, or in the acquisition of, all or
any portion of a business as a going concern or of developed, undeveloped or
mixed real property, in an arms-length transaction between the Company and an
unaffiliated third party, whether such acquisition shall be effected by purchase
of assets, exchange of securities, merger, consolidation or otherwise, (v)
[Preferred] [Common] Stock issued in a bona fide public offering pursuant to a
firm commitment underwriting or (vi) [Preferred] [Common] Stock issued on
exercise of rights if and to the extent Holders of Securities have received or
are entitled to receive such rights upon conversion.

SECTION 12.10.    ADJUSTMENT FOR CONVERTIBLE SECURITIES ISSUE.

    If the Company issues any securities convertible into or exchangeable or
exercisable for [Preferred] [Common] Stock (other than the Securities or
securities issued in transactions described in Sections 12.07 and 12.08) for a
consideration per share of [Preferred] [Common] Stock initially deliverable upon
conversion, exchange or exercise of such securities less than the current market
price per share on the date of issuance of such securities, the conversion price
shall be adjusted in accordance with this formula:


                                            O + P
                                                -
                                   C' = C x     M
                                            -----
                                            O + D

where:

        C' = the adjusted conversion price.

        C = the then current conversion price.



                                       55
   64
        O      = the number of shares outstanding immediately prior to the
                 issuance of such securities.

        P      = the aggregate consideration received for the issuance of such
                 securities (including as determined in Section 12.12(3)).

        M      = the current market price per share on the date of issuance of
                 such securities.

        D      = the maximum number of shares deliverable upon conversion or in
                 exchange for or upon exercise of such securities at the
                 initial conversion, exchange or exercise rate.

    The adjustment shall be made successively whenever any such issuance is
made, and shall become effective immediately after such issuance. If all of the
[Preferred] [Common] Stock deliverable upon conversion, exchange or exercise of
such securities have not been issued when such securities are no longer
convertible, exchangeable or exercisable, then the conversion price shall
promptly be readjusted to the conversion price which would then be in effect had
the adjustment upon the issuance of such securities been made on the basis of
the actual number of shares of [Preferred] [Common] Stock issued upon
conversion, exchange or exercise of such securities.

    This Section does not apply to (1) convertible securities issued to acquire,
or in the acquisition of, all or any portion of a business as a going concern or
of developed, undeveloped or mixed real property, in an arms-length transaction
between the Company and an unaffiliated third party, whether such acquisition
shall be effected by purchase of assets, exchange of securities, merger,
consolidation or otherwise, or (ii) convertible securities issued in a bona fide
public offering pursuant to a firm commitment underwriting.

SECTION 12.10A.    SPECIAL PROVISION REGARDING PREFERRED STOCK.

    In addition to the foregoing adjustments and without duplication, if (x)
prior to the exercise of a Security an event ("Event") occurs which, under the
Certificate of Designations with respect to the Preferred Stock, would have
required an adjustment in the number of share(s) of Common Stock into which the
shares of Preferred Stock acquired on conversion of the Securities would have
been convertible if such Security had previously been converted into Preferred
Stock (but such Preferred Stock acquired on conversion had not been converted
into Common Stock), then (y) after the Event, such share of Preferred Stock
shall, when acquired on conversion of the Security, be convertible into the same
number of share(s) of Common Stock into which it would have been convertible if
such Security had been converted into Preferred Stock (but such Preferred Stock
acquired on conversion had not been converted into Common Stock) prior to the
Event.



                                       56
   65
The adjustment required by the foregoing sentence shall be made each time there
is an Event, provided that no adjustment shall be made under this Section 12.10A
unless that adjustment results in a change of 1%, provided further that all
adjustments not made by virtue of the preceding "provided" clause shall be
carried forward and made when the aggregate of all such adjustments results in a
change of at least 1%.]*

SECTION 12.11.    CURRENT MARKET PRICE.

    In Sections 12.07, 12.08, 12.09 and 12.10, the current market price per
share of [Preferred] [Common] Stock on any date is the average of the Quoted
Prices (as defined in Section 12.03) of the [Preferred] [Common] Stock for 20
consecutive trading days commencing 30 trading days before the date in question.
In the absence of one or more such quotations, the Company shall determine the
current market price on the basis of such quotations or other information as it
considers appropriate.

SECTION 12.12.    CONSIDERATION RECEIVED.

    For purposes of any computation respecting consideration received pursuant
to Sections 12.09 and 12.10, the following shall apply:

               (1) in the case of the issuance of shares of [Preferred] [Common]
        Stock for cash, the consideration shall be the amount of such cash,
        provided that in no case shall any deduction be made for any
        commissions, discounts or, without limitation, other expenses incurred
        by the Company for any underwriting of the issue or otherwise in
        connection therewith,

               (2) in the case of the issuance of shares of [Preferred] [Common]
        Stock for a consideration in whole or in part other than cash, the
        consideration other than cash shall be deemed to be the fair market
        value thereof as determined in good faith by the Board of Directors
        (irrespective of the accounting treatment thereof), whose determination
        shall be conclusive, and described in a Board resolution which shall be
        filed with the Trustee; and

               (3) in the case of the issuance of securities convertible into or
        exchangeable or exercisable for shares, the aggregate

________________
*  This provision will be used, if at all, if the Securities are exercisable for
   Preferred Stock which is convertible into Common Stock.

                                       57
   66
        consideration received therefor shall be deemed to be the consideration
        received by the Company for the issuance of such securities plus the
        additional minimum consideration, if any, to be received by the Company
        upon the conversion or exchange thereof (the consideration in each case
        to be determined in the same manner as provided in clauses (1) and (2)
        of this Section).

SECTION 12.13.    WHEN ADJUSTMENT MAY BE DEFERRED.

    No adjustment in the conversion price need be made unless the adjustment
would require an increase or decrease of at least 1% in the conversion price.
Any adjustments that are not made shall be carried forward and taken into
account in any subsequent adjustment.

    All calculations under this Article shall be made to the nearest cent or to
the nearest 1/100th of a share, as the case may be.

SECTION 12.14.    WHEN NO ADJUSTMENT REQUIRED.

    No adjustment need be made for a transaction referred to in Sections 12.06,
12.07, 12.08, 12.09 or 12.10 if all Securityholders are entitled to participate
in the transaction on a basis and with notice that the Board of Directors
determines to be fair and appropriate in light of the basis and notice on which
holders of [Preferred] [Common] Stock participate in the transaction.

    No adjustment need be made for rights to purchase [Preferred] [Common] Stock
pursuant to a Company plan for reinvestment of dividends or interest.

    No adjustment need be made for a change in the par value or no par value of
the [Preferred] [Common] Stock.

    To the extent the Securities become convertible into cash, no adjustment
need be made thereafter as to the cash. Interest will not accrue or be deemed to
accrue on the cash for this purpose.

    In any case in which this Article 12 or the Securities shall require that an
adjustment in the conversion price be made effective as of a record date for a
specified event and notwithstanding anything to the contrary in this Article 12
of the Securities, the Company may elect to defer until the occurrence of such
event the issuing to the holder of any Security converted after such record
date, the [Preferred] [Common] Stock or other capital stock of the Company, if
any, issuable upon such conversion over and above the [Preferred] [Common] Stock
or other capital stock of the Company, if any, issuable upon such conversion on
the basis of the



                                       58
   67
conversion price in effect prior to such adjustment; provided, however, [that
the Company shall deliver to such holder a due bill or other appropriate
instrument evidencing, subject to the following proviso, such holder's right to
receive such additional shares upon the occurrence of the event requiring such
adjustment and, provided further,] to the extent such event does not occur, the
adjustment made in respect of such non-occurrence shall be retroactive and
affect each conversion security converted between such Record Date and the date
of such non-occurrence.

SECTION 12.15.    NOTICE OF ADJUSTMENT.

    Whenever the conversion price is adjusted, the Company shall promptly mail
to Securityholders a notice of the adjustment. The Company shall file with the
Trustee a certificate from the Company's independent public accountants briefly
stating the facts requiring the adjustment and the manner of computing it. The
certificate shall be conclusive evidence that the adjustment is correct, absent
manifest error.

SECTION 12.16.    VOLUNTARY REDUCTION.

    The Company from time to time may reduce the conversion price by any amount
for any period of time if the period is at least [20] days and if the reduction
is irrevocable during the period; provided that in no event may the conversion
price be less than the then par value of a share of [Preferred] [Common] Stock,
if any.

    Whenever the conversion price is reduced, the Company shall mail to
Securityholders a notice of the reduction. The Company shall mail the notice at
least 15 days before the date the reduced conversion price takes effect. The
notice shall state the reduced conversion price and the period it will be in
effect.

    A reduction of the conversion price does not change or adjust the conversion
price otherwise in effect for purposes of Sections 12.06, 12.07, 12.08, 12.09
and 12.10.

SECTION 12.17.    NOTICE OF CERTAIN TRANSACTIONS.

    If:

               (1) the Company takes any action that would require an adjustment
        in the conversion price pursuant to Sections 12.06, 12.07, 12.08, 12.09
        or 12.10 and if the Company does not let Securityholders participate
        pursuant to Section 12.14 [or which is referred to in Section 12.10A];

                                       59
   68
               (2) the Company takes any action that would require a
        supplemental indenture pursuant to Section 12.18; or

               (3)  there  is  a  liquidation  or  dissolution  of  the
        Company,

the Company shall mail to Securityholders and to the Trustee a notice stating
the proposed record date, proposed effective date or other relevant proposed
date of the act in question. The Company shall mail the notice at least [15]
days before such date. Failure to mail the notice or any defect in it shall not
affect the validity of the transaction.

SECTION 12.18.    REORGANIZATION OF COMPANY.

    If the Company is a party to a transaction subject to Section 5.01, or a
transaction which reclassifies or changes its outstanding [Preferred] [Common]
Stock, upon consummation of such transaction the Securities shall automatically
become convertible into the kind and amount of securities, cash or other assets
which the Holder of a Security would have owned immediately after the
transaction if the Holder had converted the Security immediately before the
effective date of the transaction. Concurrently with the consummation of such
transaction, the person obligated to issue securities or deliver cash or other
assets upon conversion of the Securities shall enter into a supplemental
indenture so providing and further providing for adjustments which shall be as
nearly equivalent as may be practical to the adjustments provided for in this
Article. The Company or, if applicable, the other person shall mail to
Securityholders a notice describing the transaction and supplemental indenture.

    If securities deliverable upon conversion of Securities, as provided above,
are themselves convertible into the securities of an Affiliate of the other
person, that Affiliate shall join in the supplemental indenture and the
supplemental indenture shall so provide.

    If this Section applies, Section 12.06 does not apply.

SECTION 12.19.    COMPANY DETERMINATION FINAL.

    Any determination that the Company or the Board of Directors must make
pursuant to Section 12.03, 12.06, 12.08, 12.09, 12.10, 12.11, 12.12 or 12.14 is
conclusive.

SECTION 12.20.    TRUSTEE'S DISCLAIMER.

    The Trustee has no duty to determine when an adjustment under this Article
should be made, how it should be made or what it should be. The Trustee has no
duty to determine whether any provisions of a supplemental



                                       60
   69
indenture under Section 12.18 are correct. The Trustee makes no representation
as to the validity or value of any securities or assets issued upon conversion
of Securities. The Trustee shall not be responsible for the Company's failure to
comply with this Article. Each Conversion Agent other than the Company shall
have the same protection under this Section as the Trustee.]

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

            ___% [Convertible] Senior Subordinated [Debenture] [Note]
                                 Due __________

    1. Interest. Del Webb Corporation, a Delaware corporation (the "Company"),
promises to pay interest on the principal amount of this Security at the rate
per annum shown above. The Company will pay interest semiannually on _________
and _________ of each year. Interest on the Securities will accrue from the most
recent date to which interest has been paid or, if no interest has been paid,
from _________, 199_. Interest will be computed on the basis of a 360-day year
of twelve 30-day months.

    2. Method of Payment. The Company will pay interest on the Securities
(except defaulted interest) to the persons who are registered holders of
Securities at the close of business on the record date for the next interest
payment date even though Securities are canceled after the record date and on or
before the interest payment date. Holders must surrender Securities to a Paying
Agent to collect principal payments. The Company will pay principal and interest
in money of the United States that at the time of payment is legal tender for
payment of public and private debts. However, the Company may pay principal and
interest by check payable in such money. It may mail an interest check to a
holder's registered address.

    3. Paying Agent [, and] Registrar [and Conversion Agent]. [Bank of Montreal
Trust Company] (the "Trustee") will act as Paying Agent [,and] Registrar [and
Conversion Agent]. The Company may change the Paying Agent, Registrar or
co-registrar without prior notice. The Company or any of its subsidiaries may
act in any such capacity.

    4. Indenture. The Company issued the Securities under an Indenture dated as
of ___________, 199_ [as modified by a Supplemental Indenture dated as of ______
__________________, 199_] ([collectively, ]the "Indenture") between the Company
and the Trustee. The terms of the Securities include those stated in the
Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939 (15 U.S. Code Sections 77aaa-77bbbb) as in effect on
the date of the Indenture. The Securities are subject to, and qualified by, all
such terms, certain of which are summarized hereon, and Securityholders are
referred to the Indenture and such Act for a statement of such terms. The
Securities are unsecured general obligations of the Company limited to
$__________ in aggregate principal amount [of which $___________ may only be
issued as 'Additional Securities' on or before the 30th day after the date of,
and pursuant to the terms of, that certain Underwriting Agreement dated
_________, 199_ by and between the Company and _________________. The Company
will not originally issue any Additional



                                       A-2
   72
Securities except pursuant to the Underwriting Agreement. If no Additional
Securities are issued the Securities will be limited to $____________ in
aggregate principal amount.] Capitalized terms not defined below have the same
meaning as is given to them in the Indenture.

    5[A]. Optional Redemption. The Company may not redeem the Securities prior
to ____________. Thereafter, the Company may redeem all the Securities at any
time or some of them from time to time at the redemption prices (expressed in
percentages of principal amount) set forth below plus accrued interest to the
redemption date, if redeemed during the 12-month period beginning _________ of
the years starting with _____ indicated below.

    Year                Percentage         Year               Percentage




                                       and

                                              thereafter      100.000

    [5B. Mandatory Redemption. The Company will redeem ___% of the [initial]
principal amount of Securities [(including any Additional Securities)] [then
outstanding] on ____________, and on each _________ thereafter through
___________ at a redemption price of 100% of principal amount, plus accrued
interest to the redemption date. The Company may reduce the principal amount of
Securities to be redeemed pursuant to this paragraph 6 by subtracting 100% of
the principal amount (excluding premium) of any Securities that [Securityholders
have converted,] the Company has delivered to the Trustee for cancellation or
the Company has previously purchased, redeemed, retired or acquired other than
pursuant to this paragraph 6, provided that the Company may so subtract the same
Security only once.]

    6. Notice of Redemption. Notice of redemption will be mailed at least 30
days but not more than 60 days before the redemption date to each holder of
Securities to be redeemed at his or her registered address. Securities in
denominations larger than $1,000 may be redeemed in part but only in whole
multiples of $1,000. In the event of a redemption of less than all of the
Securities, the Securities will be chosen for redemption by the Trustee,
generally pro rata or by lot. On and after the redemption date interest ceases
to accrue on Securities or portions of them called for redemption.

    If this Security is redeemed subsequent to a record date with respect to any
interest payment

                                      A-3
   73
date specified above and on or prior to such interest payment date, then any
accrued interest will be paid to the person in whose name this Security is
registered at the close of business on such record date.

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

    8. Subordination. To the extent set forth in Article 11 of the Indenture,
the Securities are subordinated to Senior Indebtedness, which generally is any
Indebtedness outstanding on the date of the Indenture or Indebtedness thereafter
created, incurred, assumed or guaranteed by the Company and all renewals,
extensions and refundings thereof except Indebtedness that expressly provides
that it is not senior to or superior in right of payment to the Securities.
Senior Indebtedness does not include Indebtedness of the Company to any of its
subsidiaries, trade payables of the Company and certain Indebtedness of others
guaranteed by the Company. Indebtedness, for any specified person, is any
indebtedness, contingent or otherwise, in respect of borrowed money (whether or
not the recourse of the lender is to the whole of the assets of the 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 leases and all direct
or indirect obligations which arise as a result of claims under or drawings
pursuant to surety, performance, completion or maintenance bonds. To the extent
provided in the Indenture, Senior Indebtedness must be paid before the
Securities may be paid. The Company agrees, and each Securityholder by accepting
a Security agrees, to the subordination and authorizes the Trustee to give it
effect.

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


                                       A-4
   74
    10. Persons Deemed Owners. The registered holder of a Security may be
treated as its owner for all purposes.

    11. Amendments and Waivers. Subject to certain exceptions, the Indenture or
the Securities may be amended with the consent of the holders of at least a
majority in principal amount of the then outstanding Securities and any existing
default may be waived with the consent of the holders of a majority in principal
amount of the then outstanding Securities. Without the consent of any
Securityholder, the Indenture or the Securities may be amended: to cure any
ambiguity, defect or inconsistency; to provide for assumption of the Company's
obligations to Securityholders; to make any change that does not adversely
affect the rights of any Securityholder; to add to the covenants of the Company,
for the benefit of the Securityholders; or to modify the Indenture to effect its
qualification under the TIA.

    12. Defaults and Remedies. An Event of Default is: default for 30 days in
payment of interest on the Securities; default in payment of principal of and
premium, if any, on the Securities; failure by the Company for 60 days after
notice to it to comply with any of its other agreements in the Indenture or the
Securities or, in the case of failure by the Company to maintain its corporate
existence or to comply with the restrictions on payments of dividends and other
distributions, the restrictions on consolidation, merger or transfer or lease of
substantially all its assets [or the provisions regarding conversion of the
Securities], with such notice but without such passage of time; certain defaults
under and accelerations prior to maturity of certain Indebtedness; certain final
judgments which remain undischarged; and certain events of bankruptcy or
insolvency. If an Event of Default occurs and is continuing, the Trustee or the
holders of at least 25% in principal amount of the then outstanding Securities
may declare all the Securities to be due and payable immediately, except that in
the case of an Event of Default arising from certain events of bankruptcy or
insolvency, all outstanding Securities become due and payable without further
action or notice. Securityholders may not enforce the Indenture or the
Securities except as provided in the Indenture. The Trustee may require
indemnity satisfactory to it before it enforces the Indenture or the Securities.
Subject to certain limitations, holders of a majority in principal amount of the
then outstanding Securities may direct the Trustee in its exercise of any trust
or power. The Trustee may withhold from Securityholders notice of any continuing
default (except a default in payment of principal or interest) if it determines
that withholding notice is in their interests. The Company must furnish an
annual compliance certificate to the Trustee.

    13. Trustee Dealings with the Company. [Bank of Montreal Trust Company], the
Trustee under the Indenture, or any of its Affiliates, in their individual or
any other capacities, may make or continue loans to or guaranteed by, accept
deposits from and perform services for the Company or its Affiliates and may
otherwise deal with the Company or its Affiliates as if [Bank of Montreal Trust
Company] were not Trustee.

                                       A-5
   75
    14. No Recourse Against Others. No director, officer, employee or
stockholder, as such, of the Company shall have any liability for any
obligations of the Company under the Securities or the Indenture or for any
claim based on, in respect of or by reason of such obligations or their
creation. Each Securityholder by accepting a Security waives and releases all
such liability. The waiver and release are part of the consideration for the
Securities.

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

    16. Abbreviations. Customary abbreviations may be used in the name of a
Securityholder or an assignee, such as: TEN CO = tenants in common, TEN ENT =
tenants by the entireties, JT TEN = joint tenants with right of survivorship and
not as tenants in common, CUST = Custodian and U/G/M/A = Uniform Gifts to Minors
Act.

    The Company will furnish to any Securityholder upon written request and
without charge a copy of the Indenture, which has in it the text of this
Security in larger type. Requests may be made to: Treasurer, Del Webb
Corporation, 2231 East Camelback Road, P.O. Box 29040, Phoenix, AZ 85016.

    [17. Conversion. A holder of a Security may convert it into [Preferred]
[Common] Stock of the Company at any time before the close of business on
________,_____. If the Security is called for redemption, the holder may convert
it at any time before the close of business on the redemption date (unless the
Company shall default in payment due upon redemption thereof). The initial
conversion price of $__ per share is subject to adjustment in certain events. To
determine the number of shares issuable upon conversion of a Security, divide
the principal amount to be converted by the conversion price in effect on the
conversion date. On conversion, no payment or adjustment for interest will be
made. However, interest will be paid on any interest payment date with respect
to Securities surrendered for conversion after a record date for the payment of
interest to the registered holder on such record date. The Company will deliver
a check for any fractional share.

    To convert a Security a holder must (1) complete and sign the conversion
notice on the back of the Security, (2) surrender the Security to a Conversion
Agent, (3) furnish appropriate endorsements and transfer documents if required
by the Registrar or Conversion Agent and (4) pay any transfer or similar tax if
required by the Indenture or applicable law. A holder may convert a portion of a
Security if the portion is $1,000 or an integral multiple of $1,000.

    The conversion price is subject to adjustment as set forth in the Indenture
in certain events. No adjustment in the conversion price will be required unless
such adjustment would require a change of at least 1% in the price then in
effect; but any adjustment that would otherwise be required to be made shall be
carried forward and taken into account in any subsequent adjustment.

                                       A-6
   76
    The Company from time to time may voluntarily reduce the conversion price
for a period of time.

    If the Company is a party to a consolidation or merger or a transfer or
lease of all or substantially all of its assets, the Securities automatically
become convertible into the kind and amount of securities, cash or other assets
which the Holder of a Security would have owned immediately after such
transaction if the Holder had converted the Security immediately before the
effective date of the transaction.]
