series of Securities, being referred to herein as the "Indenture").


                             RECITALS OF THE COMPANY

pursuant to the terms of this Supplemental Indenture and substantially in the
form set forth below, in each case with such appropriate insertions, omissions,
substitutions, and other variations as are required or permitted by the Base

private debts; provided, however, that at the option of the Company payment of
interest may be made by check mailed to the address of the Person entitled

      Section 201. Certain Definitions. The terms defined in this Section 201
(except as herein otherwise expressly provided or unless the context of this
Supplemental Indenture otherwise requires) for all purposes of this Supplemental
Indenture and of any indenture supplemental hereto have the respective meanings
specified in this Section 201. All other terms used in this Supplemental
Indenture that are defined in the Base Indenture or the Trust Indenture Act,
either directly or by reference therein (except as herein otherwise expressly
provided or unless the context of this Supplemental Indenture otherwise
requires), have the respective meanings assigned to such terms in the Base
Indenture or the Trust Indenture Act, as the case may be, as in force at the
date of this Supplemental Indenture as originally executed.

Person is at the time liable for a term of more than 12 months, at any date as
of which the amount thereof is to be determined, the total net amount of rent
required to be paid by such Person under such lease during the remaining term
thereof (excluding any subsequent renewal or other extension options held by the
lessee), discounted from the respective due dates thereof to such date at a rate
per annum equal to the prevailing market interest rate, at the time such lease
was entered into, on United States Treasury obligations having a maturity
substantially the same as the average term of such lease, plus 3%. The net
amount of rent required to be paid under any such lease for any such period
shall be the aggregate amount of the rent payable by the lessee with respect to
such period after excluding amounts required to be paid by such lessee, whether
or not designated as rent or additional rent, on account of maintenance and
repairs, services, insurance, taxes, assessments, water rates and similar
charges and contingent rents (such as those based on sales). In the case of any
lease which is terminable by the lessee upon the payment of a penalty, such net
amount of rent shall include the lesser of (i) the total discounted net amount
of rent required to be paid from the later of the first date upon which such
lease may be so terminated or the date of the determination of such net amount
of rent, as the case may be, and (ii) the amount of such penalty (in which event
no rent shall be considered as required to be paid under such lease subsequent
to the first date upon which it may be so terminated).

date of calculation, (ii) all goodwill, trade names, trademarks, patents,
unamortized debt discount and expense and other like intangibles and (iii)
appropriate adjustments on account of minority interests of other Persons
holding stock of the Company's Subsidiaries, all as set forth on the most recent

                                CERTAIN COVENANTS

      Subject to Article Fourteen of the Base Indenture, the following covenants
shall be applicable to the Company for so long as any of the Notes are
outstanding in addition to the covenants contained in the Base Indenture.

      Section 301. Limitation on Liens. The Company will not itself, and will
not permit any Restricted Subsidiary to, create, incur, issue or assume any Debt
secured by any Lien on any Principal Property owned by the Company or any
Restricted Subsidiary, and the Company will not itself, and will not permit any
Restricted Subsidiary to, create, incur, issue or assume any Debt secured by any
Lien on any shares of stock or Debt of any Restricted Subsidiary (such shares of
stock or Debt of any Restricted Subsidiary being called "Restricted
Securities"), without in any such case effectively providing that the Notes
(together with, if the Company shall so determine, any other Debt of the Company
or such Restricted Subsidiary then existing or thereafter created which is not
subordinate to the Notes) shall be secured equally and ratably with (or prior
to) such secured Debt, for so long as such other secured Debt shall be so
secured, unless after giving effect thereto, the aggregate principal amount of
all such secured Debt then outstanding plus the Attributable Debt of the Company
and its Restricted Subsidiaries in respect of Sale and Leaseback Transactions
involving Principal Properties entered into after the date of the first issuance
by the Company of Notes under this Supplemental Indenture (other than Sale and
Leaseback Transactions permitted by paragraph (b) of Section 302 hereof) would
not exceed an amount equal to 10% of the Company's Consolidated Net Tangible
Assets; provided, however, that nothing contained in this Section 301 shall
prevent, restrict or apply to, and there shall be excluded from secured Debt in
any computation under this Section 301, Debt secured by:

            (a) Liens on any Principal Property or Restricted Securities of the
      Company or any Subsidiary existing as of the date of the first issuance by
      the Company of the Notes;

            (b) Liens on any Principal Property or Restricted Securities of any
      Person existing at the time such Person becomes a Restricted Subsidiary,
      or arising thereafter whether or not the obligations secured by such Liens
      are assumed by the Company or a Restricted Subsidiary (i) otherwise than
      in connection with the borrowing of money arranged thereafter and (ii)
      pursuant to contractual commitments entered into prior to and not in
      contemplation of such Person's becoming a Restricted Subsidiary;

            (c) Liens on any Principal Property or Restricted Securities of the
      Company or any Subsidiary existing at the time of acquisition thereof
      (including acquisition through


                                        7
<PAGE>   9
      merger or consolidation or acquisition of stock or assets or otherwise) or
      securing the payment of all or any part of the purchase price or
      construction cost of the Principal Property or Restricted Securities or
      securing any Debt incurred prior to, at the time of or within 180 days
      after the acquisition of such Principal Property or Restricted Securities
      or the completion of any such construction, whichever is later, for the
      purpose of financing all or any part of the purchase price or construction
      cost thereof (provided such Liens are limited to such Principal Property
      or Restricted Securities, to improvements on such Principal Property and
      to any other property or assets not then constituting a Principal Property
      or Restricted Security);

            (d) Permitted Liens;

            (e) to the extent not covered by (d) above, pledges or deposits,
      Liens resulting from litigation or judgments, taxes or other governmental
      charges or landlord or tenant rights and other Liens incidental to the
      conduct of the business or the ownership of the property and assets of the
      Company or a Restricted Subsidiary which were not incurred in connection
      with borrowing of money or the obtaining of advances or credit, and which
      do not, in the opinion of the Company, materially detract from the value
      of the property or assets or materially impair the use thereof in the
      operation of the business of the Company and its Restricted Subsidiaries,
      taken as a whole;

            (f) Liens on any property to secure all or part of the cost of
      improvements or construction thereon or indebtedness incurred to provide
      funds for such purpose in a principal amount not exceeding the cost of
      such improvements or construction;

            (g) Liens which secure Debt owing by a Subsidiary to the Company or
      to a Restricted Subsidiary; and

            (h) any extension, renewal, substitution or replacement (or
      successive extensions, renewals, substitutions or replacements), as a
      whole or in part, of any of the Liens referred to in paragraphs (a)
      through (g) above or the Debt secured thereby; provided that (1) such
      extention, renewal, substitution or replacement Lien shall be limited to
      all or any part of the same Principal Property or Restricted Securities
      that secured the Lien extended, renewed, substituted or replaced (plus
      improvements or expansions on such property, and plus any other property
      or assets not then constituting a Principal Property or Restricted
      Securities) and (2) in the case of paragraphs (a) through (g) above, the
      Debt secured by such Lien at such time is not increased (except to pay for
      any premium, interest, fee or expense payable in connection with any such
      replacement, extension or renewal).

      For the purposes of this Section 301 and Section 302 hereof, the giving of
a guarantee which is secured by a Lien on a Principal Property or Restricted
Securities, and the creation of a Lien on a Principal Property or Restricted
Securities to secure Debt which existed prior to the creation of such Lien,
shall be deemed to involve the creation of Debt in an amount equal to the
principal


                                        8
<PAGE>   10
amount guaranteed or secured by such Lien; but the amount of Debt secured by
Liens on Principal Properties and Restricted Securities shall be computed
without cumulating the underlying indebtedness with any guarantee thereof or
Lien securing the same.

      Section 302. Limitation on Sales and Leasebacks. The Company will not
itself, and will not permit any Restricted Subsidiary to, enter into any
arrangement after the date of the first issuance by the Company of the Notes
with any bank, insurance company or other lender or investor (other than the
Company or another Restricted Subsidiary) providing for the leasing by the
Company or any such Restricted Subsidiary of any Principal Property (except a
lease for a temporary period not to exceed three years by the end of which it is
intended that the use of such Principal Property by the lessee will be
discontinued), which was or is owned or leased by the Company or a Restricted
Subsidiary and which has been or is to be sold or transferred by the Company or
a Restricted Subsidiary, more than 180 days after the completion of construction
and commencement of full operation thereof by the Company or such Restricted
Subsidiary, to such lender or investor who has advanced or will advance funds on
the security of such Principal Property (herein referred to as a "Sale and
Leaseback Transaction") unless, (i) the gross proceeds of the sale or transfer
of the Principal Property leased equals or exceeds the fair market value of such
Principal Property and (ii) either:

            (a) the Attributable Debt of the Company and its Restricted
      Subsidiaries in respect of such Sale and Leaseback Transaction and all
      other Sale and Leaseback Transactions entered into after the date of the
      first issuance by the Company of the Notes (other than such Sale and
      Leaseback Transactions as are permitted by paragraph (b) below), plus the
      aggregate principal amount of Debt secured by Liens on Principal
      Properties and Restricted Securities then outstanding (excluding any such
      Debt secured by Liens covered in paragraphs (a) through (h) of Section 301
      hereof) without equally and ratably securing the Notes, would not exceed
      10% of the Company's Consolidated Net Tangible Assets, or

            (b) the Company, within 180 days after the sale or transfer, applies
      or causes a Restricted Subsidiary to apply an amount equal to the greater
      of the net proceeds of such sale or transfer or fair market value of the
      Principal Property so sold and leased back at the time of entering into
      such Sale and Leaseback Transaction (in either case determined by any two
      of the following: the Chairman, the President, any Vice President, the
      Treasurer and the Controller of the Company) to (i) purchase other
      Principal Property having a fair market value at least equal to the fair
      market value of the Principal Property (or portion thereof) sold or
      transferred in such Sale and Leaseback Transaction or (ii) the retirement
      of the Notes or other Debt of the Company (other than Debt subordinated to
      the Notes) or Debt of a Restricted Subsidiary, having a Maturity more than
      12 months from the date of such application (or which is supported by
      other borrowings with a maturity of more than 12 months from the date of
      application) or which is extendible at the option of the obligor thereon
      to a date more than 12 months from the date of such application; provided
      that the amount to be so applied shall be reduced by (i) the principal
      amount of Notes delivered within 180 days after such sale or transfer to
      the Trustee for retirement and cancellation, and


                                        9
<PAGE>   11
      (ii) the principal amount of any such Debt of the Company or a Restricted
      Subsidiary, other than Notes, voluntarily retired by the Company or a
      Restricted Subsidiary within 180 days after such sale or transfer, or

            (c) such Sale and Leaseback Transaction involves property of a
      Person existing at the time such Person becomes a Restricted Subsidiary of
      the Company or at the time of the sale, lease or other disposition of the
      properties of such Person as an entirety or substantially as an entirety
      to the Company, in each case (i) otherwise than in connection with the
      borrowing of money arranged thereafter and (ii) pursuant to contractual
      commitments related to the Sale and Leaseback Transaction entered into
      prior to and not in contemplation of such merger, sale, lease or
      disposition or such Person's becoming a Restricted Subsidiary.

      Notwithstanding the foregoing, where the Company or any Restricted
Subsidiary is the lessee in any Sale and Leaseback Transaction, Attributable
Debt shall not include any Debt resulting from the guarantee by the Company or
any other Restricted Subsidiary of the lessee's obligation thereunder.

      Section 303. Maintenance of Properties. The Company will cause all
Principal Properties owned by the Company or any Restricted Subsidiary or used
or held for use in the conduct of its business or the business of any Restricted
Subsidiary to be maintained and kept in good condition, repair and working order
and supplied with all necessary equipment (except for ordinary wear and tear)
and will cause to be made all necessary repairs, renewals and replacements
thereof, all as in the judgment of the Company may be necessary so that the
business carried on in connection therewith may be properly conducted at all
times; provided, however, that nothing in this Section 303 shall prevent the
Company or any Restricted Subsidiary from discontinuing the operation or
maintenance of any Principal Properties if such discontinuation is, in the
judgment of the Company, desirable in the conduct of its business or the
business of any Restricted Subsidiary and not reasonably expected to have a
material adverse effect on the ability of the Company to perform its obligations
hereunder.

      Section 304. Insurance. The Company shall keep all of its and its
Restricted Subsidiaries' Principal Properties which are of an insurable nature
insured with insurers, believed by the Company in good faith to be financially
sound and responsible, against loss or damage to the extent that property of
similar character is usually so insured by corporations similarly situated and
owning like properties engaged in similar operations in the same general
geographic areas in which the Company and its Restricted Subsidiaries operate,
except where the failure to do so could not reasonably be expected to have a
material adverse effect on the condition (financial or otherwise), earnings,
business affairs or prospects of the Company and its Restricted Subsidiaries,
taken as a whole, provided that such insurance is generally available at
commercially reasonable rates, and further provided that the Company may
self-insure, or insure through captive insurers or insurance cooperatives to the
extent consistent with prudent business practices. Such insurance shall be in
such amounts, contain such terms, be in such forms and be for such periods as
are customary in the


                                       10
<PAGE>   12
Company's industry and commercially reasonable. Such insurance may be subject to
such deductibles as are customary in the industry.

      Section 305. Payment of Taxes and Other Claims. The Company will pay or
discharge or cause to be paid or discharged, before the same shall become
delinquent, (i) all material taxes, assessments and governmental charges levied
or imposed upon it or any Subsidiary or upon the income, profits or property of
the Company or any Subsidiary, and (ii) all material and lawful claims for
labor, materials and supplies which, if unpaid, might by law become a lien upon
the property of the Company or any Subsidiary, except for any Lien permitted to
be incurred under Section 301; provided, however, that the Company shall not be
required to pay or discharge or cause to be paid or discharged any such tax,
assessment, charge or claim whose amount, applicability or validity is being
contested in good faith by appropriate proceedings.

                               REDEMPTION OF NOTES

      Section 401. Right of Redemption. The Notes may be redeemed, as a whole or
in part, at the option of the Company at any time, at a redemption price (a
"Redemption Price") equal to the greater of (i) 100% of the principal amount of
such Notes and (ii) the sum of the present values of the remaining scheduled
payments of principal and interest thereon discounted to the redemption date
(the "Redemption Date") on a semiannual basis (assuming a 360-day year
consisting of twelve 30-day months) at the Treasury Rate plus 25 basis points,
plus in each case accrued interest thereon to the Redemption Date.

      "Treasury Rate" means, with respect to any Redemption Date, the rate per
annum equal to the semiannual equivalent yield to maturity of the Comparable
Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as
a percentage of its principal amount) equal to the Comparable Treasury Price for
such Redemption Date.

      "Comparable Treasury Issue" means the United States Treasury security
selected by an Independent Investment Banker as having a maturity comparable to
the remaining term of the Notes to be redeemed that would be utilized, at the
time of selection and in accordance with customary financial practice, in
pricing new issues of corporate debt securities of a comparable maturity to the
remaining term of such Notes. "Independent Investment Banker" means one of the
Reference Treasury Dealers appointed by the Trustee after consultation with the
Company.

      "Comparable Treasury Price" means, with respect to any Redemption Date,
(A) the average of the Reference Treasury Dealer Quotations for such Redemption
Date, after excluding the highest and lowest such Reference Treasury Dealer
Quotations, or (B) if the Trustee obtains fewer than four such Reference
Treasury Dealer Quotations, the average of all such quotations. "Reference
Treasury Dealer Quotations" means, with respect to each Reference Treasury
Dealer and any Redemption Date, the average, as determined by the Trustee, of
the bid and asked prices for the Comparable


                                       11
<PAGE>   13
Treasury Issue (expressed in each case as a percentage of its principal amount)
quoted in writing to the Trustee by such Reference Treasury Dealer at 3:30 p.m.,
New York time, on the third business day preceding such Redemption Date.

      "Reference Treasury Dealer" means each of Merrill Lynch, Pierce, Fenner &
Smith Incorporated and three other primary U.S. Government securities dealers in
The City of New York to be selected by the Company, and their respective
successors.

      Notice of any redemption will be mailed at least 30 days but not more than
60 days before the Redemption Date to each holder of Notes to be redeemed.

      Unless the Company defaults in payment of the Redemption Price, on and
after the Redemption Date interest will cease to accrue on the Notes or portions
thereof called for redemption.

      If less than all of the Notes are to be redeemed, the Trustee will select
the Notes to be redeemed by such method as the Trustee shall deem fair and
appropriate. The Trustee may select for redemption Notes and portions of Notes
in amounts of whole multiples of $1,000.

the purposes of this series of Securities supersede the provisions of the Base
Indenture to the extent the Base Indenture is inconsistent herewith.

particular instance to comply with any term, provision, or condition set forth
in Article Three hereof if, before or after the time for such compliance, the
Holders of a majority in principal amount of the Outstanding Notes shall, by Act
of such Holders, either waive such compliance in such instance or generally
waive compliance with such term, provision or condition, but no such waiver
shall extend to or affect such term, provision, or condition except to the
extent so expressly waived, and, until such waiver shall become effective, the
obligations of the Company and the duties of the Trustee in respect of any such
term, provision, or condition shall remain in full force and effect.

Notes shall be construed as if such invalid or illegal or unenforceable
provision had never been contained herein or therein.

                           FORM OF REVERSE OF SECURITY

      This Security is one of a duly authorized issue of securities of the
Company (herein called the "Securities"), issued and to be issued in one or more
series under an Indenture, dated as of September 23, 1998 (herein called the
"Indenture," which term shall have the meaning assigned to it in such
instrument), between the Company and Norwest Bank Arizona, N.A., as Trustee
(herein called the "Trustee," which term includes any successor trustee under
the Indenture), and reference is hereby made to the Indenture and all indentures
supplemental thereto for a statement of the respective rights, limitations of
rights, duties and immunities thereunder of the Company, the Trustee and the
Holders of the Securities and of the terms upon which the Securities are, and
are to be, authenticated and delivered. This Security is one of the series
designated on the face hereof, limited in aggregate principal amount to
$200,000,000, and is issued pursuant to a Supplemental Indenture supplementing
the Indenture, dated as of September 23, 1998, between the Company and the
Trustee relating to the issuance of the "6 1/2% Senior Notes due 2008" of this
series (the "Supplemental Indenture").

      The Notes may be redeemed, as a whole or in part, at the option of the
Company at any time, at a redemption price equal to the greater of (i) 100% of
the principal amount of such Notes and (ii) the sum of the present values of the
remaining scheduled payments of principal and interest thereon discounted to the
redemption date (the "Redemption Date") on a semiannual basis (assuming a 360-
day year consisting of twelve 30-day months) at the Treasury Rate plus 25 basis
points, plus in each case accrued interest thereon to the Redemption Date.

      In the event of redemption of this Security in part only, a new Security
or Securities of this series and of like tenor for the unredeemed portion hereof
will be issued in the name of the Holder hereof upon the cancellation hereof.

      The Indenture contains provisions for defeasance at any time of the entire
indebtedness of this Security or certain restrictive covenants and Events of
Default with respect to this Security, in each case upon compliance with certain
conditions set forth in the Indenture.

      If an Event of Default with respect to Securities of this series shall
occur and be continuing, the principal of the Securities of this series may be
declared due and payable in the manner and with the effect provided in the
Indenture.

      The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Company and the Trustee with the
consent of the Holders of more than 50% in principal amount of the Securities at
the time Outstanding of each series to be affected. The Indenture also contains
provisions permitting the Holders of specified percentages in principal amount
of the Securities of each series at the time Outstanding, on behalf of the
Holders of all Securities of such series, to waive compliance by the Company
with certain provisions of the Indenture and certain past defaults under the
Indenture and


                                        4
<PAGE>   22
their consequences. Any such consent or waiver by the Holder of this Security
shall be conclusive and binding upon such Holder and upon all future Holders of
this Security and of any Security issued upon the registration of transfer
hereof or in exchange herefor or in lieu hereof, whether or not notation of such
consent or waiver is made upon this Security.

      As provided in and subject to the provisions of the Indenture, the Holder
of this Security shall not have the right to institute any proceeding with
respect to the Indenture or for the appointment of a receiver or trustee or for
any other remedy thereunder, unless such Holder shall have previously given the
Trustee written notice of a continuing Event of Default with respect to the
Securities of this series, the Holders of not less than 25% in principal amount
of the Securities of this series at the time Outstanding shall have made written
request to the Trustee to institute proceedings in respect of such Event of
Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee
shall not have received from the Holders of a majority in principal amount of
Securities of this series at the time Outstanding a direction inconsistent with
such request, and shall have failed to institute any such proceeding, for 60
days after receipt of such notice, request and offer of indemnity. The foregoing
shall not apply to any suit instituted by the Holder of this Security for the
enforcement of any payment of principal hereof or any premium or interest hereon
on or after the respective due dates expressed herein.

      No reference herein to the Indenture and no provision of this Security or
of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and any premium and interest
on this Security at the times, place and rate, and in the coin or currency,
herein prescribed.

      As provided in the Indenture and subject to certain limitations therein
set forth, the transfer of this Security is registrable in the Security
Register, upon surrender of this Security for registration of transfer at the
office or agency of the Company in any place where the principal of and any
premium and interest on this Security are payable, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar duly executed by, the Holder hereof or its
attorney duly authorized in writing, and thereupon one or more new Securities of
this series and of like tenor, of authorized denominations and for the same
aggregate principal amount, will be issued to the designated transferee or
transferees.

      The Securities of this series are issuable only in registered form without
coupons in denominations of $1,000 and any integral multiple thereof. As
provided in the Indenture and subject to certain limitations therein set forth,
Securities of this series are exchangeable for a like aggregate principal amount
of Securities of this series and of like tenor of a different authorized
denomination, as requested by the Holder surrendering the same.

      No service charge shall be made to a Holder for any such registration of
transfer or exchange, but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.

have the meanings assigned to them in the Indenture.
