      TRUSTEE FOR CANCELLATION PURSUANT TO SECTION 2.11 OF THE INDENTURE AND
      (IV) THIS GLOBAL NOTE MAY BE TRANSFERRED TO A SUCCESSOR DEPOSITARY WITH
      THE PRIOR WRITTEN CONSENT OF THE COMPANY."

      (h) Cancellation and/or Adjustment of Global Notes. At such time as all
beneficial interests in a particular Global Note have been exchanged for
Definitive Notes or a particular Global Note has been redeemed, repurchased or
cancelled in whole and not in part, each such Global Note shall be returned to
or retained and cancelled by the Trustee in accordance with Section 2.11 hereof.
At any time prior to such cancellation, if any beneficial interest in a Global
Note is exchanged for or transferred to a Person who will take delivery thereof
in the form of a beneficial interest in another Global Note or for Definitive
Notes, the principal amount of Notes represented by such Global Note shall be
reduced accordingly and an endorsement shall be made on such Global Note, by the
Trustee or by the Depositary at the direction of the Trustee, to reflect such
reduction; and if the beneficial interest is being exchanged for or transferred
to a Person who will take delivery thereof in the form of a beneficial interest
in another Global Note, such other Global Note shall be increased accordingly
and an endorsement shall be made on such Global Note, by the Trustee or by the
Depositary at the direction of the Trustee, to reflect such increase.

      (i) General Provisions Relating to Transfers and Exchanges.

      (i) To permit registrations of transfers and exchanges, the Company shall
   execute and the Trustee shall authenticate Global Notes and Definitive Notes
   upon the Company's order or at the Registrar's request.

      (ii) No service charge shall be made to a holder of a beneficial interest
   in a Global Note or to a Holder of a Definitive Note for any registration of
   transfer or exchange, 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 taxes or similar
   governmental charge payable upon exchange or transfer pursuant to Sections
   2.10, 3.06, 4.08, and 9.05 hereof).

      (iii) The Registrar shall not be required to register the transfer of or
   exchange any Security selected for redemption in whole or in part, except the
   unredeemed portion of any Security being redeemed in part.

      (iv) All Global Notes and Definitive Notes issued upon any registration of
   transfer or exchange of Global Notes or Definitive Notes shall be the valid
   obligations of the Company, evidencing the same debt, and entitled to the
   same benefits under this Indenture, as the Global Notes or Definitive Notes
   surrendered upon such registration of transfer or exchange.

      (v) The Company shall not be required (A) to issue, to register the
   transfer of or to exchange Securities during a period beginning at the
   opening of business 15 days before the day of mailing of a notice of
   redemption under Section 3.02 hereof and ending at the close of business on
   the day of selection, (B) to register the transfer of or to exchange any
   Security so selected for redemption in whole or in part, except the
   unredeemed portion of any Security being redeemed in part or (C) to register
   the transfer of or to exchange a Security between a record date and the next
   succeeding Interest Payment Date.

      (vi) Prior to due presentment for the registration of a transfer of any
   Security, the Trustee, any Agent and the Company may deem and treat the
   Person in whose name any Security is registered as the absolute owner of such
   Security for the purpose of receiving payment of principal of and interest on
   such Securities and for all other purposes, and none of the Trustee, any
   Agent or the Company shall be affected by notice to the contrary. 


                                       24


      (vii) The Trustee shall authenticate Global Notes and Definitive Notes in
   accordance with the provisions of Section 2.02 hereof.

      (viii) All certifications, certificates and Opinions of Counsel required
   to be submitted to the Registrar pursuant to this Section 2.06 to effect a
   transfer or exchange may be submitted by facsimile.

SECTION 2.07. REPLACEMENT NOTES

      If any mutilated Note is surrendered to the Trustee or the Company and the
Trustee receives evidence to its satisfaction of the destruction, loss or theft
of any Note, the Company shall issue and the Trustee, upon receipt of an
Authentication Order, shall authenticate a replacement Note if the Trustee's
requirements are met. If required by the Trustee or the Company, an indemnity
bond must be supplied by the Holder that is sufficient in the judgment of the
Trustee and the Company to protect the Company, the Trustee, any Agent and any
authenticating agent from any loss that any of them may suffer if a Note is
replaced. The Company may charge for its expenses in replacing a Note.

      Every replacement Note is an additional obligation of the Company and
shall be entitled to all of the benefits of this Indenture equally and
proportionately with all other Notes duly issued hereunder.

SECTION 2.08. OUTSTANDING NOTES .

      The Notes outstanding at any time are all the Notes authenticated by the
Trustee except for those cancelled by it, those delivered to it for
cancellation, those reductions in the interest in a Global Note effected by the
Trustee in accordance with the provisions hereof, and those described in this
Section as not outstanding. Except as set forth in Section 2.09 hereof, a Note
does not cease to be outstanding because the Company or an Affiliate of the
Company holds the Note; however, Notes held by the Company or a Subsidiary of
the Company shall not be deemed to be outstanding for purposes of Section
3.07(b) hereof.

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

      If the principal amount of any Note is considered paid under Section 4.01
hereof, it ceases to be outstanding and interest on it ceases to accrue.

      If the Paying Agent (other than the Company, a Subsidiary or an Affiliate
of any thereof) holds, on a redemption date or maturity date, money sufficient
to pay Notes payable on that date, then on and after that date such Notes shall
be deemed to be no longer outstanding and shall cease to accrue interest.

SECTION 2.09. TREASURY NOTES .

      In determining whether the Holders of the required principal amount of
Notes have concurred in any direction, waiver or consent, Notes owned by the
Company, or by any Person directly or indirectly controlling or controlled by or
under direct or indirect common control with the Company, shall be considered as
though 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 Notes that the Trustee knows are so owned shall be so disregarded.

SECTION 2.10. TEMPORARY NOTES .

      Until certificates representing Notes are ready for delivery, the Company
may prepare and the Trustee, upon receipt of an Authentication Order, shall
authenticate temporary Notes. Temporary Notes shall be substantially in the form
of certificated Notes but may 


                                       25


have variations that the Company considers appropriate for temporary Notes and
as shall be reasonably acceptable to the Trustee. Without unreasonable delay,
the Company shall prepare and the Trustee shall authenticate definitive Notes in
exchange for temporary Notes.

      Holders of temporary Notes shall be entitled to all of the benefits of
this Indenture.

SECTION 2.11. CANCELLATION .

      The Company at any time may deliver Notes to the Trustee for cancellation.
The Registrar and Paying Agent shall forward to the Trustee any Notes
surrendered to them for registration of transfer, exchange or payment. The
Trustee and no one else shall cancel all Notes surrendered for registration of
transfer, exchange, payment, replacement or cancellation. The Company may not
issue new Notes to replace Notes that it has paid or that have been delivered to
the Trustee for cancellation.

SECTION 2.12. DEFAULTED INTEREST .

      If the Company defaults in a payment of interest on the Notes, it shall
pay the defaulted interest in any lawful manner plus, to the extent lawful,
interest payable on the defaulted interest, to the Persons who are Holders on a
subsequent special record date, in each case at the rate provided in the Notes
and in Section 4.01 hereof. The Company shall notify the Trustee in writing of
the amount of defaulted interest proposed to be paid on each Note and the date
of the proposed payment. The Company shall fix or cause to be fixed each such
special record date and payment date, provided that no such special record date
shall be less than 10 days prior to the related payment date for such defaulted
interest. At least 15 days before the special record date, the Company (or, upon
the written request of the Company, the Trustee in the name and at the expense
of the Company) shall mail or cause to be mailed to Holders a notice that states
the special record date, the related payment date and the amount of such
interest to be paid.

SECTION 2.13 CUSIP NUMBERS

      The Company in issuing the Notes may use "CUSIP" numbers (if then
generally in use), and, if so, the Trustee shall use "CUSIP" numbers in notices
of redemption as a convenience to Holders; provided that any such notice may
state that no representation is made as to the correctness of such numbers
either as printed on the Notes or as contained in any notice of redemption and
that reliance may be placed only on the other identification numbers printed on
the Notes, and any such redemption shall not be affected by any defect in or
omission of such numbers. The Company will promptly notify the Trustee of any
change in the "CUSIP" numbers.

                                    ARTICLE 3
                             OPTIONAL REDEMPTION AND
                   OPTIONAL REDEMPTION UPON CHANGE OF CONTROL

SECTION 3.01 NOTICES TO TRUSTEE

      (a) If the Company elects to redeem Securities pursuant to the optional
redemption provisions of Section 3.07 hereof, it shall furnish to the Trustee,
at least 45 days but not more than 60 days before a redemption date, an
Officers' Certificate setting forth that such redemption shall occur pursuant to
Section 3.07 hereof and setting forth the redemption date, the principal amount
of Securities to be redeemed and the redemption price.

      (b) If the Company elects to redeem Securities pursuant to the provisions
of Section 3.08 hereof, it shall furnish to the Trustee, at least 45 days but
not more than 60 days before the redemption date, an Officers' Certificate
setting forth that a Change of Control has occurred and the date of such Change
of Control and that such redemption shall occur pursuant to Section 3.08 hereof,
and further setting forth the principal amount of Securities to be redeemed, the
redemption price of such Securities and the intended redemption date.


                                       26


SECTION 3.02 SELECTION OF SECURITIES TO BE REDEEMED

            If less than all of the Securities are to be redeemed at any time,
selection of the Securities for redemption will be made by the Trustee in
compliance with the requirements of the principal national securities exchange,
if any, on which the Securities are listed, or, if the Securities are not listed
on a national securities exchange, on a pro rata basis, by lot or by such method
as the Trustee shall deem fair and appropriate; provided that no Security in
denominations of $1,000 or less shall be redeemed in part. The Trustee may
select for redemption any portion (equal to $1,000 or any integral multiple
thereof) of the principal of Securities that have denominations larger than
$1,000. Except as provided in the preceding sentence, provisions of this
Indenture that apply to Securities called for redemption also apply to portions
of Securities called for redemption.

            The Trustee shall promptly notify the Company in writing of the
Securities selected for redemption and, in the case of any Security selected for
partial redemption, the principal amount thereof to be redeemed. The particular
Securities to be redeemed shall be selected, unless otherwise provided herein,
not less than 30 nor more than 60 days prior to the redemption date by the
Trustee from the outstanding Securities not previously called for redemption.

SECTION 3.03 NOTICES TO HOLDERS

      (a) If the Company elects to redeem Securities pursuant to either of
Section 3.07 or 3.08 hereof, notice of redemption shall be mailed by first class
mail at least 30 days but not more than 60 days before the redemption date to
each Holder of Securities to be redeemed at its registered address.

      The notice shall identify the Securities to be redeemed (including CUSIP
number) and shall state:

            (1)   the redemption date;

            (2)   the redemption price;

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

            (4)   the name and address of the Paying Agent;

            (5)   that Securities called for redemption must be surrendered to
                  the Paying Agent at the address specified in such notice to
                  collect the redemption price;

            (6)   that interest on Securities or portions of them called for
                  redemption ceases to accrue on and after the redemption date;

            (7)   the paragraph of the Securities pursuant to which the
                  Securities are being redeemed; and

            (8)   the aggregate principal amount of Securities that are being
                  redeemed.

      (b) At the Company's timely request, the Trustee shall give the notice
required in Section 3.03(a) hereof above in the Company's name and at its
expense and setting forth the information to be stated in such notice as
provided in Section 3.03(a) hereof.


                                       27


SECTION 3.04 EFFECT OF NOTICE OF REDEMPTION

      Once notice of redemption is mailed (after the Trustee has received the
notice provided for in Section 3.01 hereof), Securities called for redemption
become due and payable on the redemption date at the redemption price and shall
cease to bear interest from and after the redemption date (unless the Company
shall fail to make payment of the redemption price or accrued interest on the
redemption date). Upon surrender to the Paying Agent, such Securities shall be
paid at the redemption price, plus premium and Liquidated Damages, if any, plus
accrued interest, if any, to the redemption date, but interest installments
whose maturity is on the redemption date and Liquidated Damages which become
payable on the redemption date will be payable to the Holder of record at the
close of business on the relevant record dates referred to in the Securities.

SECTION 3.05 DEPOSIT OF REDEMPTION PRICE OR PURCHASE PRICE

      Prior to 10:00 a.m. on the redemption date, the Company shall deposit with
the Trustee or with the Paying Agent money (in same-day funds) sufficient to pay
the redemption price of, premium and Liquidated Damages, if any, and accrued
interest on, all Securities to be redeemed on that date other than Securities or
portions thereof called for redemption on that date which previously have been
delivered by the Company to the Trustee for cancellation. The Trustee or the
Paying Agent shall return to the Company any such money not required for that
purpose.

      If the Company complies with the preceding paragraph, interest on the
Securities or portions thereof to be redeemed, whether or not such Securities
are presented for payment, will cease to accrue on the applicable redemption
date. If any Security called for redemption shall not be so paid upon surrender
for redemption because of the failure of the Company to comply with the
preceding paragraph, then interest will be paid on the unpaid principal from the
redemption date until such principal is paid and on any interest not paid on
such unpaid principal, in each case, at the rate provided in the Securities and
in Section 4.01 hereof.

SECTION 3.06 SECURITIES REDEEMED IN PART

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

SECTION 3.07 OPTIONAL REDEMPTION

      The Company may redeem all or any of the Securities, in whole or in part,
at any time on or after April 1, 2003 at the redemption prices (expressed as
percentages of the principal amount) set forth in the immediately succeeding
paragraph, plus accrued and unpaid interest thereon to the applicable redemption
date.

      The redemption price as a percentage of the principal amount shall be as
follows, if the Securities are redeemed during the twelve-month period beginning
April 1 of the year indicated below:

             Year                                  Percentage
             ----                                  ----------

             2003                                   103.813%
             2004                                   102.542%
             2005                                   101.271%
             2006 and thereafter                    100.000%

      Notwithstanding the foregoing, upon the occurrence at any time of a Change
in Control, the Securities will be redeemable, at the option of the Company, in
whole or in part, pursuant to the provisions of Section 3.08 hereof.


                                       28


      Any redemption pursuant to this Section 3.07 shall be made, to the extent
applicable, pursuant to the provisions of Sections 3.01 through 3.06 hereof.

SECTION 3.08 OPTIONAL REDEMPTION UPON CHANGE OF CONTROL

      In addition to any redemption pursuant to Section 3.07 hereof, the
Securities will be redeemable, at the option of the Holders, in whole or in
part, at any time within 160 days after a Change of Control upon not less than
30 nor more than 60 days' prior notice to the Company of Securities to be
redeemed, at a redemption price equal to the sum of (i) the then outstanding
principal amount of the Securities being redeemed plus Liquidated Damages for
such Securities, if any, plus (ii) accrued and unpaid interest, if any, to the
redemption date plus (iii) the Applicable Premium.

      Any redemption pursuant to this Section 3.08 shall be made, to the extent
applicable, pursuant to the provisions of Sections 3.01 through 3.06 hereof.

SECTION 3.09 SINKING FUND

      The Securities will not be entitled to any sinking fund payments.

                                    ARTICLE 4
                                    COVENANTS

SECTION 4.01 PAYMENT OF SECURITIES

      The Company shall pay the principal of and interest on the Securities on
the dates and in the manner provided in the Securities, and shall pay Liquidated
Damages, if any, on the dates and in the manner provided in the Registration
Rights Agreement. Principal and interest shall be considered paid on the date
due if the Paying Agent, other than the Company or a Subsidiary of the Company,
holds on that date money deposited by the Company in available funds and
designated for and sufficient to pay all principal and interest then due.

      The Company shall pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue principal and premium, if any,
at the same rate per annum on the Securities to the extent lawful; it shall pay
interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue installments of interest (without regard to any
applicable grace period) at the same rate to the extent lawful.

SECTION 4.02 MAINTENANCE OF OFFICE OR AGENCY

      The Company shall maintain, in the Borough of Manhattan, The City of New
York, an office or agency (which may be an office of the Trustee or the
Registrar) 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 shall give prompt
written notice to the Trustee of the location, and any change in the location,
of such office or agency. 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 Corporate Trust Office of the Trustee.

      The Company may also from time to time designate one or more other offices
or agencies where the Securities may be presented or surrendered for any or all
such purposes and may from time to time rescind such designations; provided,
however, that no such designation or rescission shall in any manner relieve the
Company of its obligation to maintain an office or agency in the Borough of
Manhattan, The City of New York for such purposes. The Company shall give prompt
written notice to the Trustee of any such designation or rescission and of any
change in the location of any such other office or agency.


                                       29


      The Company hereby designates the Corporate Trust Office of the Trustee as
one such office or agency of the Company in accordance with Section 2.03 hereof.

SECTION 4.03 SEC REPORTS; FINANCIAL STATEMENTS

      (a) The Company and the Guarantors shall file with the Trustee, within 15
days after it files the same with the SEC, copies of the annual reports and the
information, documents and other reports (or copies of such portions of any of
the foregoing as the SEC may by rules and regulations prescribe) that the
Company and/or the Guarantors are required to file with the SEC pursuant to
Section 13 or 15(d) of the Exchange Act. If the Company is not subject to the
requirements of such Section 13 or 15(d), the Company shall file with the
Trustee, within 15 days after it would have been required to file the same with
the SEC, financial statements, including any notes thereto (and with respect to
annual reports, an auditors' report by a firm of established national
reputation), and a "Management's Discussion and Analysis of Financial Condition
and Results of Operations," both comparable to that which the Company would have
been required to include in such annual reports, information, documents or other
reports if the Company had been subject to the requirements of such Section 13
or 15(d). Any Guarantor not required to file with the SEC pursuant to Section 13
or 15(d) of the Exchange Act shall not be required to file such reports with the
SEC or Trustee. The Company and the Guarantors shall also comply with the other
provisions of TIA ss.314(a).

      (b) If the Company is required to furnish annual or quarterly reports to
its stockholders pursuant to the Exchange Act, the Company shall cause any
annual report furnished to its stockholders generally and any quarterly or other
financial reports furnished by it to its stockholders generally to be filed with
the Trustee and mailed to the Holders at their addresses appearing in the
register of Securities maintained by the Registrar. If the Company is not
required to furnish annual or quarterly reports to its stockholders pursuant to
the Exchange Act, so long as at least 5% of the original principal amount of the
Securities remain outstanding, the Company shall cause its financial statements
referred to in Section 4.03(a) hereof, including any notes thereto (and with
respect to annual reports, an auditors' report by a firm of established national
reputation), and a "Management's Discussion and Analysis of Financial Condition
and Results of Operations" to be so mailed to the Holders within 90 days after
the end of each of the Company's fiscal years and within 60 days after the end
of each of the Company's first three fiscal quarters. The Company will cause to
be disclosed in a statement accompanying any annual report or comparable
information as of the date of the most recent financial statements in each such
report or comparable information the amount available for payments pursuant to
Section 4.07 hereof. As of the date hereof, the Company's fiscal year ends on
December 31. Any Guarantor not required to file with the SEC pursuant to Section
13 or 15(d) of the Exchange Act shall not be required to file such reports with
the SEC or Trustee.

SECTION 4.04 COMPLIANCE CERTIFICATE

      (a) The Company shall deliver to the Trustee, within 120 days after the
end of each fiscal year of the Company, an Officers' Certificate stating that a
review of the activities of the Company and its Subsidiaries during the
preceding fiscal year has been made under the supervision of the signing
Officers with a view to determining whether the Company has kept, observed,
performed and fulfilled its obligations under this Indenture, and further
stating, as to each such Officer signing such certificate, that to the best of
his 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, provisions and conditions hereof
(or, if a Default or Event of Default shall have occurred, describing all such
Defaults or Events of Default of which he may have knowledge and what action the
Company is taking or proposes to take with respect thereto) and that to the best
of his 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 or, if such event has occurred, a description of the
event and what action the Company is taking or proposes to take with respect
thereto.

      (b) So long as not contrary to the then current recommendations of the
American Institute of Certified Public Accountants, the year-end financial
statements delivered pursuant to Section 4.03 hereof shall be accompanied by a
written statement of the Company's independent public accountants (who shall be
a firm of established national reputation) that in making the examination
necessary for certification of such financial statements nothing has come to
their attention that would lead them to believe that the Company has violated
any provisions of Articles 4 or 5 of this Indenture or, if any such violation
has occurred, specifying the nature and period of existence


                                       30


thereof, it being understood that such accountants shall not be liable directly
or indirectly to any Person for any failure to obtain knowledge of any such
violation.

      (c) The Company shall, so long as any of the Securities are outstanding,
(i) deliver to the Trustee, forthwith upon any Officer becoming aware of any
Default or Event of Default under this Indenture, an Officers' Certificate
specifying such Default or Event of Default and what action the Company is
taking or proposes to take with respect thereto and (ii) promptly notify the
Trustee of any Change of Control.

SECTION 4.05 COMPLIANCE WITH LAWS, TAXES

      The Company shall, and shall cause each of its Subsidiaries to, comply
with all statutes, laws, ordinances, or government rules and regulations to
which it is subject, noncompliance with which would materially adversely affect
the business, earnings, properties, assets or condition, financial or otherwise,
of the Company and its Subsidiaries taken as a whole.

      The Company shall, and shall cause each of its Subsidiaries to, pay prior
to delinquency all taxes, assessments, and governmental levies except as
contested in good faith and by appropriate proceedings.

SECTION 4.06 STAY, EXTENSION AND USURY LAWS

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

SECTION 4.07 LIMITATIONS ON RESTRICTED PAYMENTS

      The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly, (i) declare or pay any dividend or make
any distribution on account of the Company's or any of its Restricted
Subsidiaries' Capital Stock or other Equity Interests (other than (A) dividends
or distributions payable in Equity Interests (other than Redeemable Stock) of
the Company or such Restricted Subsidiary or (B) dividends or distributions
payable to the Company or any of its Restricted Subsidiaries), (ii) (A)
voluntarily purchase, redeem or otherwise acquire or retire for value any
preferred stock of the Company or any of its Restricted Subsidiaries, which by
its terms, is exchangeable for any Indebtedness that is pari passu with or
subordinated in right of payment to the Securities or (B) purchase, redeem or
otherwise acquire or retire for value any Equity Interests (other than
Exchangeable Preferred Stock) of the Company or any of its Restricted

otherwise acquire or retire for value any Indebtedness (other than (A) the
Securities, (B) Indebtedness under the Credit Facilities, (C) Indebtedness
permitted under clause (v) or (vi) of the second paragraph of Section 4.09
hereof, and any extension, refinancing, renewal, replacement, substitution or
refunding thereof permitted under clause (vii) of the second paragraph of
Section 4.09 hereof or (D) Indebtedness between and among the Company and its
Restricted Subsidiaries) that is pari passu with or subordinated in right of

      continuing or shall occur as a consequence thereof; or

            (b) the Company could not incur at least $1.00 of additional
      Indebtedness pursuant to the first paragraph of Section 4.09 hereof
      (without giving effect to clauses (i) through (xv) of the second paragraph
      thereof), which calculation shall be made on a pro


                                       31


      forma basis deducting from Adjusted Consolidated Net Income the amount of
      any Investment the Company has made in an Unrestricted Subsidiary during
      the relevant period and any Investment the Company intends to make in an
      Unrestricted Subsidiary, to the extent that such Investment is made with
      amounts included in Adjusted Consolidated Net Income as a result of
      Transfers described in clause (c)(x) of this Section 4.07 or clause (c)(y)
      of Section 4.14 hereof; or

      other Restricted Payments made after May 13, 1992 exceeds the sum of the
      following: (w) 50% of the amount of the Adjusted Consolidated Net Income
      (other than amounts included in the next succeeding clause (c)(x)) of the

      of the first quarter commencing immediately after May 13, 1992 through the
      end of the Company's fiscal quarter ending immediately prior to the time
      of such Restricted Payment (or, if Adjusted Consolidated Net Income for
      such period is a deficit, 100% of such deficit); plus (x) 100% of the
      amount of all Transfers from a Restricted Payment Unrestricted Subsidiary
      up to the aggregate amount of the Investment (after taking into account
      all prior Transfers from such Restricted Payment Unrestricted Subsidiary)
      in such Restricted Payment Unrestricted Subsidiary (valued in each case as
      provided in the definition of "Investment"); plus (y) in the event of a
      designation of a Restricted Payment Unrestricted Subsidiary as a
      Restricted Subsidiary, 100% of an amount equal to the greater of (A) the
      fair market value of such Subsidiary as determined by the Board of
      Directors in good faith (or, if such fair market value may exceed $25.0
      million, as determined in writing by an independent investment banking
      firm of nationally recognized standing) at the time of the redesignation
      of such Restricted Payment Unrestricted Subsidiary as a Restricted
      Subsidiary and (B) the Consolidated Net Cash Flow generated by such
      Subsidiary for the period (taken as one accounting period) from the
      beginning of its first fiscal quarter commencing immediately after the

      and other than Redeemable Stock) or (ii) the sale of the stock of an
      Unrestricted Subsidiary or the sale of all or substantially all of the
      assets of an Unrestricted Subsidiary to the extent that a liquidating

      proceeds of such sale;

provided, however, that for purposes of making Investments in Unrestricted
Subsidiaries, if the amount determined in accordance with clauses (w) or (y)
above is a deficit, such deficit shall be excluded from the computation of this
clause (c); and provided, further, that all such amounts applied pursuant to
this clause (c) shall not be available for application under clause (c) of
Section 4.14 hereof.

of declaration such payment would have complied with the provisions of this
Indenture; (ii) (A) the retirement of any shares of the Company's Capital Stock

such conversion into Common Stock; (vi) the repurchase, redemption or other

      Not later than the date of making any Restricted Payment, the Company
shall deliver to the Trustee an Officer's Certificate stating that such
Restricted Payment is permitted and setting forth the basis upon which the
calculations required by this Section 4.07 were computed, which calculations may
be based on the Company's latest available internal financial statements.

SECTION 4.08 DIVIDENDS AND PAYMENT RESTRICTIONS AFFECTING RESTRICTED
SUBSIDIARIES

      The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to

Notes and Outstanding Note Indentures, (C) the terms of Indebtedness of the
Company incurred in accordance with Section 4.09 hereof; provided that such

that the terms and conditions of any such encumbrances or restrictions contained
in any such agreement constitute no greater encumbrance or restriction on the
ability of any Restricted Subsidiary to pay dividends or make distributions,
make loans or advances or transfer properties or assets than those under or
pursuant to the agreement evidencing the Indebtedness or obligations refinanced.
Nothing contained in this Section 4.08 shall prevent the Company or a Restricted
Subsidiary from entering into any agreement permitting or providing for the
incurrence of Liens otherwise permitted by Section 4.13 hereof.

SECTION 4.09 INCURRENCE OF INDEBTEDNESS

      The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee
or otherwise become directly or indirectly liable with respect to any
Indebtedness unless the Company's Debt to Consolidated Cash Flow Ratio for its
four full fiscal quarters ending immediately prior to the date such additional
Indebtedness is created, incurred, issued, assumed or guaranteed would have been
no greater than 6 to 1, and such Indebtedness is not senior in right of payment
to the Securities; provided that such calculation shall give effect to (A) the
incurrence of any Indebtedness (after giving effect to the application of the
proceeds thereof) in connection with the simultaneous acquisition of any person,
business, property or assets and (B) the Consolidated Cash Flow generated by
such acquired person, business, property or assets, giving effect in each case
to such incurrence of Indebtedness, application of proceeds and Consolidated
Cash Flow as if such acquisition had occurred at the beginning of such four
quarter period. For purposes of the foregoing provision, cash flow generated by
any acquired person, business, property or asset shall be determined on the same
basis as the definition of Consolidated Cash Flow and shall be based on the
actual earnings before interest, taxes, depreciation and amortization of such
acquired person, business, property or asset during the immediately preceding
four full fiscal quarters plus (y) (i) the savings in cost of goods sold that
would have resulted during that period from the effect of using the Company's
actual costs for comparable goods and services during that period and (ii) other
savings in cost of goods sold or eliminations of selling, general and
administrative expenses as determined by the Company in good faith in its
consideration of such acquisitions and consistent with the Company's experiences
in acquisitions of similar businesses minus (z) the incremental expenses that
would be included in cost of goods sold and selling, general and administrative
expenses that would have been incurred by the Company in the operation of such
acquired person, business, property or assets during such period.

      The foregoing limitations shall not apply to the incurrence of (i)
Indebtedness pursuant to the Credit Facilities (provided that the principal
amount of such Indebtedness shall not exceed $1.65 billion, less the amount of
all repayments made in respect of term loans and of all permanent commitment
reductions with respect to revolving loans (except to the extent, and only to
the extent, that any required repayments of principal in connection with such
commitment reduction are not made) made under the Credit Agreements (excluding
such repayments and commitment reductions which occur substantially
contemporaneously with a refinancing or a refunding thereof)), plus any amounts
then available under clause (vi) of this paragraph; (ii) Existing Indebtedness;
(iii) Indebtedness represented by the Outstanding 


                                       34

outstanding Series G Preferred Stock; (v) Capital Lease Obligations in an
aggregate principal amount which, when aggregated with the principal amount of
all other Capital Lease Obligations then outstanding and incurred pursuant to
this clause (v) and including all Refinancing Indebtedness (as defined below)
incurred to refund, refinance or replace any other Indebtedness incurred
pursuant to this clause (v), does not exceed 5% of Total Assets; (vi)
Indebtedness in an aggregate principal amount equal to the greater of (A) $225
million in the aggregate at any one time outstanding for the Company and its
Restricted Subsidiaries or (B) Indebtedness created, incurred, issued, assumed
or guaranteed (x) by the Company at any one time outstanding not in excess of 7%
of the Consolidated Net Worth of the Company at the time of such creation,
incurrence, issuance, assumption or guarantee or (y) by any Restricted
Subsidiary of the Company at any one time outstanding not in excess of 7% of the
Consolidated Net Worth of such Restricted Subsidiary at the time of such
creation, incurrence, issuance, assumption or guarantee; (vii) Indebtedness
created, incurred, issued, assumed or guaranteed in exchange for or the proceeds
of which are used to extend, refinance, renew, replace, substitute or refund
Indebtedness referred to in clauses (i) through (vi) above, including additional
Indebtedness incurred to pay premiums and fees in connection therewith (the
"Refinancing Indebtedness"); provided, that (A) the principal amount of such
Refinancing Indebtedness shall not exceed the principal amount of Indebtedness
(including unused commitments and additional Indebtedness incurred to pay
premiums and fees in connection therewith) so extended, refinanced, renewed,
replaced, substituted or refunded plus any amounts then available under clause
(vi) of this paragraph, (B) in the case of Refinancing Indebtedness for
Indebtedness permitted under clauses (ii) and (iv) of this paragraph, the

Indebtedness being extended, refinanced, renewed, replaced, substituted or
refunded and (C) the Refinancing Indebtedness for Indebtedness permitted under
clauses (ii) and (iv) of this paragraph shall rank, in right of payment, no more
senior than such Indebtedness being extended, refinanced, renewed, replaced,
substituted or refunded and the Refinancing Indebtedness for Indebtedness
permitted under clauses (i), (iii), (v) and (vi) of this paragraph shall rank,
in right of payment, pari passu with or junior to the Securities; (viii)

Unrestricted Subsidiaries; provided that such Investments are permitted by
Section 4.07 or Section 4.14 hereof; (ix) Indebtedness under Currency Agreements
and Interest Rate Agreements, provided that in the case of Currency Agreements
which relate to other Indebtedness, such Currency Agreements do not increase the
Indebtedness of the Company outstanding other than as a result of fluctuations
in foreign currency exchange rates; (x) Indebtedness arising from agreements
providing for indemnification, adjustment of purchase price or similar
obligations, or from guarantees or letters of credit, surety bonds or
performance bonds securing any obligations of the Company or any Restricted
Subsidiary of the Company pursuant to such agreements, incurred or assumed by
the acquired Subsidiary in connection with the acquisition or disposition of any
business, assets or Restricted Subsidiary of the Company, other than guarantees
or similar credit support by the Company of Indebtedness incurred by any Person
acquiring all or any portion of such business, assets or Restricted Subsidiary
for the purpose of financing such acquisition; provided that the maximum
aggregate liability in respect of all such Indebtedness in the nature of such
guarantees shall at no time exceed the gross proceeds actually received from the
sale of such business, assets or Restricted Subsidiary; (xi) Indebtedness
arising from the honoring by a bank or other financial institution of a check,
draft or similar instrument inadvertently (except in the case of daylight
overdrafts, which will not be, and will not be deemed to be, inadvertent) drawn
against insufficient funds in the ordinary course of business, provided that
such Indebtedness is extinguished within three Business Days of its incurrence;
(xii) Indebtedness of an entity at the time it is acquired as a Restricted
Subsidiary, provided that such Indebtedness was not incurred or assumed by such
entity in connection with or in anticipation of such acquisition; (xiii)

by Section 4.07 hereof. For the purposes of determining the aggregate
Indebtedness of any referent Person, Indebtedness shall not include guarantees
by any other Person of such Indebtedness. For the purposes of determining
compliance with this Section 4.09, in the event that an item of Indebtedness
meets the criteria of more than one of the categories of permitted Indebtedness
described in clauses (i) through (xv) of this Section 4.09 or is entitled to be
incurred pursuant to the first paragraph of this Section 4.09, the Company
shall, in its sole discretion, classify such item of Indebtedness in any manner
that complies with the covenants described above and such item of Indebtedness
will be treated as having been incurred pursuant to only one of such clauses or
pursuant to the first paragraph of this Section 4.09. Accrual of interest, the
accretion of 


                                       35


accreted value and the payment of interest in the form of additional
Indebtedness will not be deemed to be an incurrence of Indebtedness for purposes
of this Section 4.09.

SECTION 4.10 CHANGE OF CONTROL

      Upon the occurrence of a Change of Control, each Holder shall have the
right to require the repurchase of such Holder's Securities pursuant to the
offer described below (the "Change of Control Offer") at a purchase price equal
to 101% of the aggregate principal amount of such Securities plus accrued and
unpaid interest, if any, to the date of purchase (the "Change of Control
Payment"). Within 40 days following any Change of Control, the Company shall
mail a notice to each Holder stating:

      (1) that the Change of Control Offer is being made pursuant to this
   Section 4.10 and that all Securities tendered will be accepted for payment;

      (2) the purchase price and the purchase date, which shall be no earlier
   than 30 days nor later than 40 days from the date such notice is mailed (the
   "Change of Control Payment Date");

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

      (4) that, unless the Company defaults in the payment of the Change of
   Control Payment, all Securities accepted for payment pursuant to the Change
   of Control Offer shall cease to accrue interest after the Change of Control
   Payment Date;

      (5) that Holders electing to have any Securities purchased pursuant to a
   Change of Control Offer will be required to surrender the Securities, with
   the form entitled "Option of Holder to Elect Purchase" on the reverse of the
   Security completed, to the Paying Agent at the address specified in the
   notice prior to the close of business on the Business Day preceding the
   Change of Control Payment Date;

      (6) that Holders will be entitled to withdraw their election if the Paying
   Agent receives, not later than the close of business on the third Business
   Day preceding the Change of Control Payment Date, a telegram, telex,
   facsimile transmission or letter setting forth the name of the Holder, the
   principal amount of the Securities delivered for purchase, and a statement
   that such Holder is withdrawing his election to have such Securities
   purchased; and

      (7) that Holders whose Securities are being purchased only in part will be
   issued new Securities equal in principal amount to the unpurchased portion of
   the Securities surrendered; provided that each Holder shall tender
   Securities, and each Security purchased and each such new Security issued by
   the Company shall be in a principal amount of $1,000 or integral multiples
   thereof.

      The Change of Control Offer shall be deemed to have commenced upon mailing
of notice described in this paragraph and shall terminate 20 Business Days after
its commencement, unless a longer offering period is required by law. If the
Change of Control Payment Date is on 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.

      On the Change of Control Payment Date, the Company shall, to the extent
lawful, (1) accept for payment Securities or portions thereof tendered pursuant
to the Change of Control Offer, (2) deposit with the Paying Agent an amount
equal to the Change of Control Payment in respect of all Securities or portions
thereof so tendered and (3) deliver or cause to be delivered to the Trustee, the
Securities so accepted together with an Officers' Certificate stating the
Securities or portions thereof were tendered to the Company. The Paying Agent
shall promptly mail to each Holder of Securities so accepted, payment in an
amount equal to the purchase price for such Securities, and the Trustee shall
promptly authenticate and mail to such Holder a new Security equal in principal
amount to any unpurchased portion of the Securities surrendered; provided that
each such new Security shall be in a principal amount of $1,000 or integral
multiples thereof. 


                                       36


The Company will publicly announce the results of the Change of Control Offer on
or as soon as practicable after the Change of Control Payment Date.

SECTION 4.11 LIMITATIONS ON ASSET SALES

      (a) The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly, consummate an Asset Sale (including the
sale of any of the stock of any Subsidiary) unless at least 100% of the Net
Proceeds from such Asset Sale (or, in the case of a Partially Owned Restricted
Subsidiary, the Company's Pro Rata Portion thereof, after repayment by such
Partially Owned Restricted Subsidiary of its Indebtedness) are applied first to
repay Obligations or reduce commitments under the Credit Facilities in
accordance with the terms thereof, second to offer to redeem at par the
Outstanding Notes and third to offer to redeem at par the Securities. The
foregoing application of Net Proceeds from Asset Sales is not required in the
case of (i) sales or dispositions generating cash proceeds of less than, with
respect to the Company, its Restricted Subsidiaries, $2.5 million and (ii) sales
and dispositions as to which the Company delivers a reinvestment notice and the
proceeds are so reinvested in one or more communications, publishing,
information, education or media assets or businesses within twelve months of the

provisions of this Section 4.11, neither the Company nor its Subsidiaries shall
be required to apply the Net Proceeds from any Asset Sale (i) to the extent that
the aggregate Net Proceeds from such Asset Sale, together with the Net Proceeds,
if any, of any other Asset Sale which have not been previously applied, are less
than $25 million or (ii) to the extent that, and for so long as, such Net

   second paragraph thereof), which calculation shall be made on a pro forma
   basis deducting from Adjusted Consolidated Net Income the amount of any
   Investment the Company has made in an Unrestricted Subsidiary during the
   relevant period and any Investment the Company intends to make in an
   Unrestricted Subsidiary, to the extent that such Investment is made with
   amounts included in Adjusted Consolidated Net Income as a result of Transfers
   described in clause (c)(x) of Section 4.07 hereof or clause (c)(y) of this
   Section 4.14; or

      (c)such Investment, together with the aggregate of all other Investments
   in Unrestricted Subsidiaries made after May 13, 1992, exceeds (w) the

without giving effect to subsequent changes in value). For the purposes of
determining compliance with this Section 4.14, in the event that the making of
an Investment in an Unrestricted Subsidiary meets the criteria of more than one
of the categories of permitted Investments in Unrestricted Subsidiaries
described in clauses (i) through (iii) above or is entitled to be incurred
pursuant to the first paragraph of this Section 4.14 (including clauses (a), (b)
and (c) thereof), the Company shall, in its sole discretion, classify such

waive or agree to amend in the time frame set forth in solicitation documents
relating to such consent, waiver or agreement.

Company shall not be required to preserve any such right, license or franchise,
or the corporate, partnership or other existence of any Restricted Subsidiary,

longer desirable in the conduct of the business of the Company and its
Restricted Subsidiaries taken as a whole and that the loss thereof is not
adverse in any material respect to the Holders.

SECTION 4.17 SUBSIDIARY OWNERSHIP.

      All Restricted Subsidiaries and all Net Cash Flow Unrestricted
Subsidiaries shall at all times remain wholly-owned, directly or indirectly, by
the Company or a Restricted Subsidiary except if sold, leased, conveyed,

Company prior to such transaction, and (y) the ratio set forth in Column C
below:

the requirements of clause (iv) of this Section 5.01.

SECTION 5.02 SUCCESSOR CORPORATION SUBSTITUTED

   any Security when the same shall become due and payable at maturity, or upon

      (4) default under any mortgage, indenture or instrument under which there
   may be issued or by which there may be secured or evidenced any Indebtedness
   for money borrowed by the Company or any of its Restricted Subsidiaries (or
   the payment of which is guaranteed by the Company or any of its Restricted
   Subsidiaries) whether such Indebtedness or guarantee is now existing or
   thereafter created in the future, if either (A) such default is the failure
   to pay the final scheduled principal installment in an amount of at least $10
   million in respect of any such Indebtedness on the stated maturity date
   thereof (after giving effect to any extension of such maturity date by the
   holder of such Indebtedness and after the expiration of any grace period in
   respect of such final scheduled principal installment contained in the
   instrument under which such Indebtedness is outstanding) or (B) as a result
   of such default the maturity of such Indebtedness has been accelerated prior
   to its express maturity and the principal amount of such Indebtedness,
   together with the principal amount of any other such Indebtedness the
   maturity of which has been accelerated, aggregates $20 million or more;
   provided that an Event of Default shall not be deemed to occur with respect
   to any accelerated Indebtedness which is repaid or prepaid within 20 days
   after such declaration;

      (5) a final judgment that exceeds $15 million individually, or final
   judgments that exceed $25 million in the aggregate, for the payment of money
   are entered by a court or courts of competent jurisdiction against the
   Company, or any of its Restricted Subsidiaries and such judgment or judgments
   shall not be discharged, satisfied, stayed, annulled or rescinded within 60
   days of being entered;

      (6) the Company or any of the Restricted Subsidiaries pursuant to or
   within the meaning of any Bankruptcy Law:

            (a)   commences a voluntary case,

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

            (c)   consents to the appointment of a Custodian of it or for all or

      (8)except as permitted by this Indenture and the Securities, the
   Guarantees shall be held in any judicial proceeding to be unenforceable or
   invalid or shall cease for any reason to be in full force and effect with
   respect to any Guarantor or any Guarantor shall deny or disaffirm its
   obligations under its Guarantee.

      The Company is required, pursuant to Section 4.04(a) hereof, to deliver to
the Trustee annually a statement regarding compliance with this Indenture, and
the Company is required, pursuant to Section 4.04(c) hereof, upon becoming aware
of any Default or Event of Default to deliver a statement to the Trustee
specifying such Default or Event of Default. The Trustee shall not be deemed to
know of a Default unless a Responsible Officer has actual knowledge of such
Default or receives written notice of such Default with specific reference to
such Default.


                                       42


      In the case of any Event of Default pursuant to the provisions of this
Section 6.01 occurring by reason of any willful action (or inaction) taken (or
not taken) by or on behalf of the Company with the intention of avoiding payment
of the premium, if any, which the Company would have had to pay if the Company
then had elected to redeem the Securities pursuant to Section 3.07 hereof, an
equivalent premium shall also become and be immediately due and payable to the
extent permitted by law, anything in this Indenture or in the Securities
contained to the contrary notwithstanding.

      A Default under clause (3) is not an Event of Default until the Trustee
notifies the Company, or the Holders of at least 30% in principal amount of the
then outstanding Securities notify the Company and the Trustee, in writing, of
the Default and the Company does not cure the Default within 30 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 with respect to the
Company specified in clauses (6) or (7) of Section 6.01 hereof) occurs and is
continuing, the Trustee by written notice to the Company, or the Holders of at
least 30% in principal amount of the then outstanding Securities by written
notice to the Company and the Trustee, may and the Trustee at the request of
such Holders shall, declare all unpaid principal of, premium and Liquidated
Damages, if any, and accrued interest on the Securities to be due and payable
immediately. Upon such declaration of acceleration such principal of, premium
and Liquidated Damages, if any, and accrued interest, due and payable on the
Securities, as determined in the next succeeding paragraph, shall be due and
payable immediately. If an Event of Default with respect to the Company
specified in clause (6) or (7) of Section 6.01 hereof occurs, all unpaid
principal of, premium and Liquidated Damages, if any, and accrued interest on
the Securities then outstanding shall ipso facto become and be immediately due
and payable without any declaration, notice or other act on the part of the
Trustee or any Holder. The Holders of at least 51% in aggregate principal amount
of the then outstanding Securities by written notice to the Trustee may rescind
an acceleration and its consequences if the rescission would not conflict with
any judgment or decree and if all existing Events of Default (except nonpayment
of principal, premium and Liquidated Damages, if any, or interest on the
Securities that has become due solely as a result of such acceleration) have
been cured or waived.

      In the event that the maturity of the Securities is accelerated pursuant
to this Section 6.02, 100% of the principal amount thereof and premium or
Liquidated Damages, if any, plus accrued interest to the date of payment shall
become due and payable.

SECTION 6.03 OTHER REMEDIES

      If an Event of Default occurs and is continuing, the Trustee may pursue
any available remedy to collect the payment of principal, premium and Liquidated
Damages, if any, or interest then due 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 Holder 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 at least 51% 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 (including waivers obtained in connection with a
tender offer or exchange offer for Securities), except a continuing Default or
Event of Default (i) in the payment of the principal of, premium or Liquidated
Damages, if any, or interest on any Security (including, without limitation,
pursuant to any mandatory or optional redemption obligation hereunder) or (ii)
that resulted from the failure to comply with Section 4.10 or 4.11 hereof. Upon
any such waiver, such Default shall cease to exist, 


                                       43


and any Event of Default arising therefrom shall be deemed to have been cured
for every purpose of this Indenture; but no such waiver shall extend to any
subsequent or other Default or impair any right consequent thereon.

SECTION 6.05 CONTROL BY MAJORITY

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

SECTION 6.06 LIMITATIONS ON SUITS

      A Holder may not pursue a remedy with respect to this Indenture, the
Securities or any Guarantee unless:

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

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

      (3) such Holder or Holders offer to the Trustee indemnity satisfactory to
   the Trustee against any loss, liability or expense (including, without
   limitation, fees and expenses of counsel);

      (4) the Trustee does not comply with the request within 30 days after
   receipt of the request and the offer of indemnity; and

      (5) during such 30-day period the Holders of a majority in principal
   amount of the then outstanding Securities do not give the Trustee a direction
   which is inconsistent with the request.

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

SECTION 6.07 RIGHTS OF HOLDERS TO RECEIVE PAYMENT

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

SECTION 6.08 COLLECTION SUIT BY TRUSTEE

      If an Event of Default specified in Section 6.01(1) or (2) or (3) (with
respect to the Company's obligations under Section 4.10 or 4.11 hereof) hereof
occurs and is continuing, the Trustee is authorized to recover judgment in its
own name and as trustee of an express trust against the Company or any Guarantor
for the amount of principal, premium, if any, and interest remaining unpaid on
the Securities, determined in accordance with Section 6.02 hereof and interest
on overdue principal, premium and Liquidated Damages, if any, and, to the extent
lawful, interest, and such further amount as shall be sufficient to cover the
costs and 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 is authorized to 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 (including any claim for the reasonable compensation, expenses,
disbursements and advances of the 


                                       44


Trustee, its agents and counsel) and the Holders allowed in any judicial
proceedings relative to the Company, its creditors or its property and shall be
entitled and empowered to collect, receive and distribute any money or other
property payable or deliverable on any such claims and any Custodian in any such
judicial proceeding is hereby authorized by each Holder to make such payments to
the Trustee, and in the event that the Trustee shall consent to the making of
such payments directly to the Holders, to pay to the Trustee any amount due to
it for the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 7.07 hereof. To the extent that the payment of any such compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, and
any other amounts due the Trustee under Section 7.07 hereof out of the estate in
any such proceeding, shall be denied for any reason, payment of the same shall
be secured by a Lien on, and shall be paid out of, any and all distributions,
dividends, money, securities and other properties which the Holders of the
Securities may be entitled to receive in such proceeding whether in liquidation
or under any plan of reorganization or arrangement or otherwise. Nothing herein
contained shall be deemed to authorize the Trustee to authorize or consent to or
accept or adopt on behalf of any Holder any plan of reorganization, arrangement,
adjustment or composition affecting the Securities or the rights of any Holder
thereof, or to authorize the Trustee to vote in respect of the claim of any
Holder in any such proceeding.

SECTION 6.10 PRIORITIES

      If the Trustee collects any money pursuant to this Article 6, it shall pay
out the money in the following order:

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

      Second: to Holders for amounts due and unpaid on the Securities for
   principal, premium and Liquidated Damages, if any, and interest, ratably,
   without preference or priority of any kind, according to the amounts due and
   payable on the Securities for principal, premium, if any, and interest,
   respectively; and

      Third: to the Company.

      The Trustee may fix a record date and payment date for any payment to
Holders pursuant to this Article 6.

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 6.11 does not apply to a suit by the Trustee, a suit by a Holder
pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in
principal amount of the then outstanding Securities.

                                    ARTICLE 7
                                     TRUSTEE

SECTION 7.01 DUTIES OF TRUSTEE

      (1) 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 such exercise, as a prudent person
would exercise or use under the circumstances in the conduct of such person's
own affairs.

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


                                       45


      (a) the Trustee need perform only those duties that are specifically set
   forth in this Indenture and no others, and no implied covenants or
   obligations shall be read into this Indenture against the Trustee; and

      (b) 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
   pursuant to and conforming to the requirements of this Indenture. However,
   the Trustee shall examine the certificates and opinions to determine whether
   or not, on their face, they appear to conform to the requirements of this
   Indenture.

      (3) 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:

            (a) this paragraph does not limit the effect of paragraph (2) of
      this Section 7.01;

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

            (c) 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 Sections 6.02 or 6.05 hereof.

      (4) Whether or not therein expressly so provided, every provision of this
Indenture that in any way relates to the Trustee is subject to paragraphs (1),
(2), (3) and (5) of this Section 7.01.

      (5) No provision of this Indenture shall require the Trustee to expend or
risk its own funds or incur any liability. The Trustee is not obligated to
perform any duty or exercise any right or power under this Indenture at the
request of the Holders of the Securities unless it receives an offer from such
Holders of security and indemnity satisfactory to it against any loss, liability
or expense (including, without limitation, fees of counsel).

      (6) 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 TRUSTEE

      (1) 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 the document.

      (2) Before the Trustee acts or refrains from acting, it may require
receipt of an Officers' Certificate or 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. The
Trustee may consult with counsel of its selection and the advice of such counsel
(to be promptly confirmed in writing) 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 and in reliance thereon.

      (3) The Trustee may act through agents, attorneys, custodians and nominees
and shall not be responsible for the misconduct or negligence of any such agent,
attorney, custodian or nominee appointed with due care.

      (4) 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 conferred upon it by this Indenture.

      (5) Unless otherwise specifically provided in this Indenture, any demand,
request, direction or notice from the Company or any Guarantor shall be
sufficient if signed by an Officer of the Company or such Guarantor. 


                                       46


SECTION 7.03 INDIVIDUAL RIGHTS OF 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 any of its
Affiliates 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 hereof.

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 or any money paid to the Company or upon the
Company's direction under any provision hereof, it shall not be responsible for
the use or application of any money received by any Paying Agent other than the
Trustee and it shall not be responsible for any statement or recital herein or
any statement in the Securities other than its certificate of authentication.

SECTION 7.05 NOTICE OF DEFAULTS

      If a Default or Event of Default occurs and is continuing and if it is
actually known to a Responsible Officer of the Trustee, the Trustee shall mail
to each Holder a notice of the Default or Event of Default within 90 days after
it occurs or, if later, within ten days after such Default or Event of Default
becomes so known to the Trustee unless such Default or Event of Default has been
cured. Except in the case of a Default or Event of Default in payment of
principal of, premium and Liquidated Damages, if any, or interest on any
Security or that resulted from a failure to comply with Section 4.10 or 4.11
hereof, the Trustee may withhold the notice if and so long as a committee of its
Responsible Officers determines in good faith that withholding the notice is in
the interests of the Holders.

SECTION 7.06 REPORTS BY TRUSTEE TO HOLDERS

      Within 60 days after each June 1 beginning with June 1, 1998, the Trustee
shall mail to Holders a brief report dated as of such reporting date that
complies with TIA ss. 313(a) (but if no event described in TIA ss. 313(a) has
occurred within the twelve months preceding the reporting date, no report need
be transmitted). The Trustee also shall comply with TIA ss. 313(b). The Trustee
also shall transmit by mail all reports as required by TIA ss. 313(c).

      A copy of each report at the time of its mailing to Holders shall be filed
with the SEC and each stock exchange on which the Securities are listed. The
Company shall 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
for its acceptance of this Indenture and services hereunder as the parties shall
agree from time to time. The Trustee's compensation shall not be limited by any
law relating to compensation of a trustee of an express trust. The Company shall
reimburse the Trustee promptly upon request for all reasonable disbursements,
advances and expenses incurred by it. Such expenses shall include the reasonable
compensation, disbursements and expenses of the Trustee's agents and counsel.

      The Company shall indemnify and hold harmless the Trustee and its
directors, officers, employees and agents against any loss, liability or expense
(including without limitation fees and expenses of counsel) incurred by it
arising out of or in connection with the acceptance or administration of its
duties under this Indenture including, without limitation, costs and expenses of
defending itself against any claim or liability in connection with the exercise
or performance of its powers and duties 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 and the Trustee
shall cooperate in the defense. The Trustee may have separate counsel and the
Company shall pay the reasonable fees and expenses of such counsel. The Company
need not pay for any settlement made without its consent, which consent shall
not be unreasonably withheld. 


                                       47


      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 7.07, 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 of,
premium and Liquidated Damages, if any, and interest on particular Securities.
Such Lien shall survive the satisfaction and discharge of the Indenture.

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

SECTION 7.08 REPLACEMENT OF TRUSTEE

      The Trustee may resign and be discharged from the trust hereby created 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 Trustee
and the Company. The Company may remove the Trustee if:

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

      (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.

The foregoing notwithstanding, 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 7.08,
and thereafter the Trustee shall have no liability for any acts or omissions of
any successor Trustee.

      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.

      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 hereof, any Holder 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 the Holders. The
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 hereof.
Notwithstanding 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.


                                       48


SECTION 7.09 SUCCESSOR TRUSTEE BY MERGER, ETC .

      Subject to Section 7.10 hereof, if the Trustee consolidates, merges or
converts into, or transfers all or substantially all of its corporate trust
business to, another corporation or national banking association, the successor
entity without any further act shall be the successor Trustee. In case any
Securities have been authenticated, but not delivered, by the Trustee then in
office, any successor by merger, conversion or consolidation of such
authenticating trustee may adopt such authentication and deliver the Securities
so authenticated with the same effect as if such successor trustee had itself
authenticated such Securities.

SECTION 7.10 ELIGIBILITY; DISQUALIFICATION

      There shall at all times be a Trustee hereunder which shall be a
corporation organized and doing business under the laws of the United States of
America, any state thereof or the District of Columbia authorized under such
laws to exercise corporate trust powers, shall be subject to supervision or
examination by Federal or state (or the District of Columbia) authority and
shall have a combined capital and surplus of at least $50 million as set forth
in its most recent published annual report of condition.

      This Indenture shall always have a Trustee who satisfies the requirements
of TIA ss. 310(a)(1). The Trustee is subject to TIA ss. 310(b).

SECTION 7.11 PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY

      The Trustee is subject to TIA ss. 311(a), excluding any creditor
relationship listed in TIA ss. 311(b). A Trustee who has resigned or been
removed shall be subject to TIA ss. 311(a) to the extent indicated therein.

                                    ARTICLE 8
                             DISCHARGE OF INDENTURE

SECTION 8.01 TERMINATION OF COMPANY'S AND GUARANTORS' OBLIGATIONS

      This Indenture shall cease to be of further effect (except that the
Company's obligations under Section 7.07 hereof and the Trustee's and Paying
Agent's obligations under Section 8.03 hereof 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 terminate all of its obligations under
this Indenture if:

      (1) the Company irrevocably deposits, or causes to be deposited, in trust
   with the Trustee or the Paying Agent, 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 U.S. Government Obligations in an amount sufficient
   (without reinvestment thereof) to pay principal and interest on the
   Securities to maturity or redemption, as the case may be, as such amounts
   become due, and to pay 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 U.S. Government
   Obligations to the Trustee and (ii) the Trustee shall have been irrevocably
   instructed to apply such money or the proceeds of such U.S. Government
   Obligations to the payment of said principal, premium and Liquidated Damages,
   if any, and interest with respect to the Securities;

      (2) the Company delivers to the Trustee an Officers' Certificate stating
   that all conditions precedent to satisfaction and discharge of this Indenture
   have been complied with, and an Opinion of Counsel to the same effect;

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


                                       49


      (4) the Company shall have delivered to the Trustee an Opinion of Counsel
   from nationally recognized counsel acceptable to the Trustee or a tax ruling
   from the Internal Revenue Service to the effect that the Holders of the
   Securities will not recognize income, gain or loss for Federal income tax
   purposes as a result of the Company's exercise of its option under this
   Section 8.01 and will be subject to Federal income tax on the same amount and
   in the same manner and at the same times as would have been the case if such
   option had not been exercised.

In such event, this Indenture shall cease to be of further effect (except as
provided in the next succeeding paragraph), and the Trustee, on demand of the
Company, shall execute proper instruments acknowledging confirmation of and
discharge under this Indenture.

      However, the Company's and the Guarantors' obligations in Sections 2.03,
2.04, 2.05, 2.06, 2.07, 4.01, 4.06, 7.07, 7.08 and 8.04 hereof and the
Company's, the Guarantors', the Trustee's and Paying Agent's obligations in
Section 8.03 hereof, and the Trustee's rights under Article 7 hereof, shall
survive until the Securities are no longer outstanding. Thereafter, only the
Company's obligations in Section 7.07 hereof and the Trustee's and Paying
Agent's obligations in Section 8.03 hereof shall survive.

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

      In order to have money available on a payment date to pay principal or
interest on the Securities, the U.S. 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. U.S. Government Obligations shall not be callable
at the issuer's option.

SECTION 8.02 APPLICATION OF TRUST MONEY

      The Trustee or a trustee satisfactory to the Trustee and the Company shall
hold in trust money or U.S. Government Obligations deposited with it pursuant to
Section 8.01 hereof. It shall apply the deposited money and the money from U.S.
Government Obligations through the Paying Agent and in accordance with this
Indenture to the payment of principal of and interest on the Securities.

SECTION 8.03 REPAYMENT TO COMPANY

      The Trustee and the Paying Agent shall promptly pay to the Company upon
written request any excess money or securities held by them at any time,
provided that nothing remains owed to the Trustee pursuant to this Indenture.

      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 that the Company shall have either caused notice of
such payment to be mailed to each Holder entitled thereto no less than 30 days
prior to such repayment or within such period shall have published such notice
in a financial newspaper of widespread circulation published in The City of New
York. After payment to the Company, Holders entitled to the money must look to
the Company for payment as general creditors unless an applicable abandoned
property law designates another Person, and all liability of the Trustee and
such Paying Agent with respect to such money shall cease.

SECTION 8.04 REINSTATEMENT

      If the Trustee or Paying Agent is unable to apply any money or U.S.
Government Obligations in accordance with Section 8.01 hereof by reason of any
legal proceeding or by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, the Company's obligations under this Indenture and the Securities
shall be revived and reinstated as though no deposit had occurred pursuant to
Section 8.01 hereof until such time as the Trustee or Paying Agent is permitted
to apply all such money or U.S. Government Obligations in accordance with
Section 8.01 hereof; provided, that if the Company has made any payment of
interest on or principal of any Securities because of the reinstatement of its
obligations, the Company shall be subrogated 


                                       50


to the rights of the Holders of such Securities to receive such payment from the
money or U.S. Government Obligations held by the Trustee or Paying Agent.

                                    ARTICLE 9
                                   AMENDMENTS

SECTION 9.01 WITHOUT CONSENT OF HOLDERS

      The Company and the Trustee may amend this Indenture, the Securities or
the Guarantee or waive any provision hereof or thereof without the consent of
any Holder:

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

      (2)   to provide for uncertificated Securities in addition to or in place
            of certificated Securities;

      (3)   to comply with Section 5.01 hereof;

      (4)   to make any change that would provide any additional rights or
            benefits to the Holders or that does not adversely affect the rights
            hereunder of any Holder; or

      (5)   to comply with requirements of the SEC in order to effect or
            maintain the qualification of this Indenture under the TIA.

      Upon the request of the Company, accompanied by a resolution of the Board
of Directors authorizing the execution of any such supplemental indenture, and
upon receipt by the Trustee of the documents described in Section 9.06 hereof,
the Trustee shall join with the Company in the execution of any supplemental
indenture authorized or permitted by the terms of this Indenture and make any
further appropriate agreements and stipulations that may be therein contained,
but the Trustee shall not be obligated to enter into any supplemental indenture
that, in its reasonable discretion, affects its own rights, duties or immunities
under this Indenture or otherwise. After an amendment or waiver under this
Section 9.01 becomes effective, the Company shall mail to the Holders of each
Security affected thereby a notice briefly describing the amendment or waiver.
Any failure of the Company to mail such notice, or any defect therein, shall
not, however, in any way impair or affect the validity of any such supplemental
indenture.

SECTION 9.02 WITH CONSENT OF HOLDERS

      Except as provided below in this Section 9.02, this Indenture, the
Securities or the Guarantee may be amended or supplemented, with the written
consent of the Holders of at least 51% in principal amount of the then
outstanding Securities (including consents obtained in connection with a tender
offer or exchange offer for Securities).

      Upon the request of the Company, accompanied by a resolution of the Board
of Directors authorizing the execution of any such supplemental indenture, and
upon the filing with the Trustee of evidence of the consent of the Holders as
aforesaid, and upon receipt by the Trustee of the documents described in Section
9.06 hereof, the Trustee shall join with the Company in the execution of such
supplemental indenture unless, in the Trustee's reasonable discretion, such
supplemental indenture affects the Trustee's own rights, duties or immunities
under this Indenture or otherwise, in which case the Trustee may in its
discretion, but shall not be obligated to, enter into such supplemental
indenture.

      It shall not be necessary for the consent of the Holders under this
Section 9.02 to approve the particular form of any proposed amendment or waiver,
but it shall be sufficient if such consent approves the substance thereof.


                                       51


      The Holders of at least 51% in principal amount of the Securities then
outstanding may waive compliance in a particular instance by the Company with
any provision of this Indenture or the Securities (including waivers obtained in
connection with a tender offer for Securities) or any existing default. However,
without the consent of each Holder affected, an amendment or waiver under this
Section may not (with respect to any Securities held by a non-consenting
Holder):

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

      (2)   reduce the principal of or change the fixed maturity of any Security
            or alter the provisions with respect to the redemption or purchase
            price in connection with repurchases under Sections 3.07, 3.08, 4.10
            or 4.11 hereof;

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

      (4)   waive a Default or Event of Default in the payment of principal of
            or premium and Liquidated Damages, if any, or interest on the
            Securities or that resulted from a failure to comply with Sections
            4.10 or 4.11 hereof (except a rescission of acceleration of the
            Securities by the Holders of at least 51% in aggregate principal
            amount of the Securities as provided in Section 6.02 hereof);

      (5)   make any Securities payable in money other than that stated in the
            Securities;

      (6)   make any change in Section 6.04 or 6.07 hereof or in this sentence
            of this Section 9.02; or

      (7)   waive a redemption payment with respect to any Security.

      The right of any Holder to participate in any consent required or sought
pursuant to any provision of this Indenture (and the obligation of the Company
to obtain any such consent otherwise required from such Holder) may be subject
to the requirement that such Holder shall have been the Holder of record of any
Securities with respect to which such consent is required or sought as of a date
identified by the Trustee in a notice furnished to Holders in accordance with
the terms of this Indenture.

SECTION 9.03 COMPLIANCE WITH TRUST INDENTURE ACT

      Every amendment to this Indenture or the Securities shall comply in form
and substance with the TIA as then in effect.

SECTION 9.04 REVOCATION AND EFFECT OF CONSENTS

      Until an amendment (which includes any supplement) 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 written notice of revocation before the date
the amendment or waiver becomes effective. An amendment or waiver becomes
effective in accordance with its terms and thereafter binds every Holder.

      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 the Company elects to fix a record date for such purpose, the record
date shall be fixed at (i) the later of 30 days prior to the first solicitation
of such consent or the date of the most recent list of Holders furnished to the
Trustee prior to such solicitation pursuant to Section 2.05 hereof, or (ii) such
other date as the Company shall designate. 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 


                                       52


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 Holder,
unless it is of the type described in any of clauses (1) through (7) of Section
9.02 hereof. In such case, the amendment or waiver shall bind each Holder of a
Security who has consented to it and every subsequent Holder of a Security that
evidences the same debt as the consenting Holder's Security.

SECTION 9.05 NOTATION ON OR EXCHANGE OF SECURITIES

      If an amendment, supplement or waiver changes the terms of a Security, the
Trustee may require the Holder of the Security to deliver it to the Trustee. The
Trustee may place an appropriate notation about the changed terms and return it
to the Holder and the Trustee may place an appropriate notation on any Security
thereafter authenticated. Alternatively, if the Company or Trustee so
determines, the Company in exchange for all Securities shall issue and the
Trustee shall authenticate new Securities that reflect the changed terms.

SECTION 9.06 TRUSTEE TO SIGN AMENDMENTS, ETC.

      The Trustee shall sign any amendment or supplemental indenture authorized
pursuant to this Article 9 if the amendment does not, in the Trustee's
reasonable discretion, adversely affect the rights, duties, liabilities or
immunities of the Trustee. If it does, the Trustee may, but need not, sign it.
In signing or refusing to sign such amendment or supplemental indenture, the
Trustee shall be entitled to receive and, subject to Section 7.01 hereof, shall
be fully protected in relying upon, an Officers' Certificate and an Opinion of
Counsel as conclusive evidence that such amendment or supplemental indenture is
authorized or permitted by this Indenture, that it is not inconsistent herewith,
and that it will be valid and binding upon the Company in accordance with its
terms.

                                   ARTICLE 10
                                    GUARANTEE

SECTION 10.01 SUBSIDIARY GUARANTEE

      Each of the Guarantors hereby, jointly and severally, fully and
unconditionally guarantees to each Holder of a Security authenticated and
delivered by the Trustee and to the Trustee and its successors and assigns,
irrespective of the validity and enforceability of this Indenture, the
Securities or the obligations of the Company hereunder or thereunder, that: (a)
the principal of, and premium and Liquidated Damages, if any, and interest on
the Securities will be promptly paid in full when due, whether at maturity, by
acceleration, redemption or otherwise, and interest on the overdue principal of,
premium and Liquidated Damages, if any, and interest on the Securities, if any,
if lawful, and all other obligations of the Company to the Holders or the
Trustee hereunder or thereunder will be promptly paid in full or performed, all
in accordance with the terms hereof and thereof; and (b) in case of any
extension of time of payment or renewal of any Securities or any of such other
obligations, the same will be promptly paid in full when due or performed in
accordance with the terms of the extension or renewal, whether at stated
maturity, by acceleration or otherwise; provided, however, that the maximum
liability of a Guarantor pursuant to this Guarantee shall in no event exceed the
Maximum Guaranteed Amount (as defined below). Failing payment when due of any
amount so guaranteed or any performance so guaranteed for whatever reason, the
Guarantors will be jointly and severally obligated to pay the same immediately.
The Guarantors hereby agree that their obligations hereunder shall be absolute
and unconditional, irrespective of the validity, regularity or enforceability of
the Securities or this Indenture, the absence of any action to enforce the same,
any waiver or consent by any Holder of the Securities with respect to any
provisions hereof or thereof, the recovery of any judgment against the Company,
any action to enforce the same or any other circumstance which might otherwise
constitute a legal or equitable discharge or defense of a guarantor other than
the defense that payment has been made or that the other relevant obligations
have been paid or performed. Each Guarantor hereby waives diligence,
presentment, demand of payment, claim of fraud, filing of claims with a court in
the event of insolvency or bankruptcy of the Company, any right to require a
proceeding first against the Company, protest, notice and all demands whatsoever
and covenant that this Guarantee will not be discharged except by complete
performance of the obligations contained in the Securities and this Indenture.
If any Holder or the Trustee is required by any court or otherwise to return to
the Company or 


                                       53


Guarantors, or any Custodian, trustee, liquidator or other similar official
acting in relation to either the Company or Guarantors, any amount paid by
either to the Trustee or such Holder, this Guarantee, to the extent theretofore
discharged, shall be reinstated in full force and effect. Each Guarantor agrees
that it shall not be entitled to any right of subrogation in relation to the
Holders in respect of any obligations guaranteed hereby until payment in full of
all obligations guaranteed hereby. Each Guarantor further agrees that, as
between the Guarantors, on the one hand, and the Holders and the Trustee, on the
other hand, (x) the maturity of the obligations guaranteed hereby may be
accelerated as provided in Article 6 for the purposes of this Guarantee,
notwithstanding any stay, injunction or other prohibition preventing such
acceleration in respect of the obligations guaranteed hereby, and (y) in the
event of any declaration of acceleration of such obligations as provided in
Article 6, such obligations (whether or not due and payable) shall forthwith
become due and payable by the Guarantors for the purpose of this Guarantee. The
Guarantors shall have the right to seek contribution from any non-paying
Guarantor so long as the exercise of such right does not impair the rights of
the Holders under the Guarantee.

      The "Maximum Guaranteed Amount" means, with respect to any Guarantor, the
amount which allows the Guarantee to be enforceable to the fullest extent
permitted by law, limited only to the extent necessary for the Guarantee to not
constitute a fraudulent conveyance.

      The "Adjusted Net Worth" of a Guarantor as of the Guarantee Date shall
mean the excess of (a) the amount of the fair saleable value of the assets of
such Guarantor as of such date determined in accordance with applicable federal
and state laws governing determinations of the insolvency of debtors over (b)
the amount of all liabilities of such Guarantor, contingent or otherwise, as of
the Guarantee Date, determined on the basis provided in clause (a) above
(excluding all liabilities under this Guarantee).

      Each Guarantor shall be subrogated to all rights of each Holder of any
Securities against the Company in respect of any amounts paid to the Holders by
such Guarantor pursuant to the provisions of this Guarantee; provided that the
Guarantors shall not be entitled to enforce, or to receive, any payments arising
out of or based upon, such right of subrogation until the principal of, premium
and Liquidated Damages, if any, and interest on all the Securities shall have
been paid in full and nothing remains owed to the Trustee pursuant to this
Indenture.

      The Guarantee set forth in this Section 10.01 shall not be valid or become
obligatory for any purpose with respect to a Security until the certificate of
authentication on such Security shall have been signed by or on behalf of the
Trustee.

      No Unrestricted Subsidiary or Partially Owned Restricted Subsidiary shall
become a guarantor of any Indebtedness of the Company or any Restricted
Subsidiaries unless such Unrestricted Subsidiary or Partially Owned Restricted
Subsidiary becomes a guarantor of the Notes.

SECTION 10.02 EXECUTION AND DELIVERY OF GUARANTEE

      To evidence its Guarantee set forth in Section 10.01 hereof, each
Guarantor hereby agrees that a notation of such Guarantee substantially in the
form of Exhibit A-1 shall be endorsed by an officer of such Guarantor on each
Security authenticated and delivered by the Trustee and that this Indenture
shall be executed on behalf of such Guarantor by its President or one of its
Vice Chairmen or Vice Presidents.

      Each Guarantor hereby agrees that its Guarantee set forth in Section 10.01
shall remain in full force and effect notwithstanding any failure to endorse on
each Security a notation of such Guarantee.

      If an officer or Officer whose signature is on this Indenture of on the
Guarantee no longer holds that office at the time the Trustee authenticates the
Security on which a Guarantee is endorsed, the Guarantee shall be valid, binding
and enforceable nevertheless.

      The delivery of any Security by the Trustee, after the authentication
thereof hereunder, shall constitute due delivery of the Guarantee set forth in
this Indenture on behalf of the Guarantors.


                                       54


SECTION 10.03 GUARANTORS MAY CONSOLIDATE, ETC., ON CERTAIN TERMS

      (a) Except as set forth in Articles 4 and 5 hereof, nothing contained in
this Indenture or in any of the Securities shall prevent any consolidation or
merger of a Guarantor with or into the Company or another Guarantor or shall
prevent any sale or conveyance of the property of a Guarantor as an entirety or
substantially as an entirety, to the Company or another Guarantor. Upon any such
consolidation, merger, sale or conveyance, the Guarantee given by such Guarantor
shall no longer have any force or effect.

      (b) Except as set forth in Articles 4 and 5 hereof, nothing contained in
this Indenture or in any of the Securities shall prevent any consolidation or
merger of a Guarantor with or into a corporation or corporations other than the
Company or another Guarantor (whether or not affiliated with the Guarantor), or
successive consolidations or mergers in which a Guarantor or its successor or
successors shall be a party or parties, or shall prevent any sale or conveyance
of the property of a Guarantor as an entirety or substantially as an entirety,
to a corporation other than the Company or another Guarantor (whether or not
affiliated with the Guarantor) authorized to acquire and operate the same;
provided that each such Guarantor is sold or disposed of for fair market value,
evidenced by a resolution of the Board of Directors set forth in an Officer's
Certificate delivered to the Trustee; and provided, further, that the foregoing
proviso shall not apply to the sale or disposition of a Guarantor in a
foreclosure proceeding to the extent that such proviso would be inconsistent
with the Uniform Commercial Code. Upon any such consolidation, merger, sale or
conveyance, the Guarantee given by such Guarantor shall no longer have any force
or effect.

SECTION 10.04 RELEASES FOLLOWING SALE OF ASSETS

      Concurrently with any sale of assets (including, if applicable, all of the
capital stock of any Guarantor), any Liens in favor of the Trustee in the assets
sold thereby shall be released; provided that any such assets are sold or
disposed of for fair market value, evidenced by a resolution of the Board of
Directors set forth in an Officer's Certificate delivered to the Trustee and,
provided, further, that, the foregoing proviso shall not apply to the sale or
disposition of a Guarantor in a foreclosure proceeding to the extent that such
proviso would be inconsistent with the Uniform Commercial Code. If the assets
sold in such sale or other disposition include all or substantially all of the
assets of any Guarantor or all of the capital stock of any Guarantor, then such
Guarantor (in the event of a sale or other disposition of all of the capital
stock of such Guarantor) or the corporation acquiring the property and such
Guarantor (in the event of a sale or other disposition of all or substantially
all of the assets of a Guarantor) shall automatically be released and relieved
of its obligations under this Article 10, provided that any such sale or
disposition of all or substantially all of the assets of a Guarantor is sold or
disposed of for fair market value, evidenced by a resolution of the Board of
Directors set forth in an Officer's Certificate delivered to the Trustee and,
provided, further, that the foregoing proviso shall not apply to the sale or
disposition of a Guarantor in a foreclosure proceeding to the extent that such
proviso would be inconsistent with the Uniform Commercial Code. Upon delivery by
the Company to the Trustee of an Officers' Certificate and an Opinion of Counsel
to the effect that such sale or other disposition was made by the Company in
accordance with the provisions of this Indenture, the Trustee shall execute any
documents reasonably required in order to evidence the release of any Guarantor
from its obligations under its Guarantee. Any Guarantor not released from its
obligations under its Guarantee shall remain liable for the full amount of
principal of and interest on the Securities and for the other obligations of any
Guarantor under the Indenture as provided in this Article 10.

SECTION 10.05 "TRUSTEE" TO INCLUDE PAYING AGENT

      In case at any time any Paying Agent other than the Trustee shall have
been appointed by the Company and be then acting hereunder, the term "Trustee"
as used in this Article 10 shall in such case (unless the context shall
otherwise require) be construed as extending to and including such Paying Agent
within its meaning as fully and for all intents and purposes as if such Paying
Agent were named in this Article 10 in place of the Trustee.


                                       55


SECTION 10.06 ADDITIONAL SUBSIDIARY GUARANTEES

      The Company shall (a) cause each Subsidiary which, after the date of this
Indenture (if not then a Guarantor), becomes a Restricted Subsidiary to execute
a Guarantee of the Obligations of the Company hereunder in the form set forth in
this Article 10 hereof and Exhibit A-1 hereto, provided that no Subsidiary
organized outside of the United States of America and no Unrestricted Subsidiary
shall be required to be a Guarantor, and (b) deliver to the Trustee an Opinion
of Counsel, in form reasonably satisfactory to the Trustee, that such Subsidiary
Guarantee is a valid, binding and enforceable obligation of such Restricted
Subsidiary, subject to customary exceptions for bankruptcy, fraudulent
conveyance and equitable principles and the implied covenant of good faith and
fair dealing.

      "THE SECURITY (OR ITS PREDECESSOR) EVIDENCED HEREBY WAS ORIGINALLY ISSUED
      IN A TRANSACTION EXEMPT FROM REGISTRATION UNDER SECTION 5 OF THE UNITED
      STATES SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND THE

      TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE EXEMPTION
      THEREFROM. EACH PURCHASER OF THE SECURITY EVIDENCED HEREBY IS HEREBY
      NOTIFIED THAT THE SELLER MAY BE RELYING ON THE EXEMPTION FROM THE
      PROVISIONS OF SECTION 5 OF THE SECURITIES ACT PROVIDED BY RULE 144A OR
      REGULATION S THEREUNDER. THE HOLDER OF THE SECURITY EVIDENCED HEREBY
      AGREES FOR THE BENEFIT OF THE COMPANY THAT (A) SUCH SECURITY MAY BE
      RESOLD, PLEDGED OR OTHERWISE TRANSFERRED, ONLY (1)(a) INSIDE THE UNITED
      STATES TO A PERSON WHO THE SELLER REASONABLY BELIEVES IS A QUALIFIED

      STATEMENT AND, IN EACH CASE, IN ACCORDANCE WITH ANY APPLICABLE SECURITIES
      LAWS OF ANY STATE OF THE UNITED STATES OR ANY OTHER APPLICABLE
      JURISDICTION AND (B) THE HOLDER WILL, AND EACH SUBSEQUENT HOLDER IS
      REQUIRED TO, NOTIFY ANY PURCHASER FROM IT OF THE SECURITY EVIDENCED HEREBY
      OF THE RESALE RESTRICTIONS SET FORTH IN (A) ABOVE."

      Capitalized terms used herein have the meaning assigned to them in the
Indenture unless otherwise indicated.

            1. INTEREST; LIQUIDATED DAMAGES. The Company promises to pay
      interest on the principal amount of this Security at 7 5/8 per annum from
      the date of issuance until maturity and shall pay the Liquidated Damages
      payable pursuant to Section 5 of the Registration Rights Agreement. The
      Company will pay interest and Liquidated Damages, if any, semi-annually on
      April 1 and October 1 of each year, or if any such day is not a Business
      Day, on the next succeeding Business Day (each an "Interest Payment
      Date"). Interest on the Securities will accrue from the most recent date
      on which interest has been paid or, if no interest has been paid, from the
      date of issuance; provided that if there is no existing Default in the
      payment of interest, and if this Security is authenticated between a
      record date referred to on the face hereof and the next succeeding
      Interest Payment Date, interest shall accrue from such next succeeding
      Interest Payment Date; provided, further, that the first Interest Payment
      Date shall be October 1, 1998. The Company shall pay interest (including
      post-petition interest in any proceeding under any Bankruptcy Law) on
      overdue principal and premium, if any, from time to time on demand at the
      same rate per annum on the Securities to the extent lawful; it shall pay
      interest (including post-petition interest in any proceeding under any
      Bankruptcy Law)


                                      A-2


      on overdue installments of interest (without regard to any applicable
      grace periods) from time to time on demand at the same rate to the extent
      lawful. 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) and premium and Liquidated Damages,
      if any, to the Persons who are registered Holders of Securities at the
      close of business on the March 15 or September 15 next preceding the
      Interest Payment Date, even if such Securities are cancelled after such
      record date and on or before such Interest Payment Date. The Securities
      will be payable as to principal, premium, interest and Liquidated Damages
      at the office or agency of the Company maintained for such purpose within
      or without the City and State of New York, or, at the option of the
      Company, payment of interest, premium and Liquidated Damages may be made
      by check mailed to the Holders of the Securities at their addresses set
      forth in the register of Holders of Securities.

            3. PAYING AGENT AND REGISTRAR. Initially, The Bank of New York, the
      Trustee under the Indenture, will act as Paying Agent and Registrar. The
      Company may change any Paying Agent, Registrar or co-registrar without
      notice to any Holder. The Company or any of its Subsidiaries may act in
      any such capacity.

            4. INDENTURE. The Company issued the Securities under an Indenture
      dated as of February 17, 1998 (the "Indenture") among the Company, the
      Guarantors 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 TIA (15 U.S. Code ss.ss. 77aaa-77bbbb). The Securities are subject
      to all such terms, and Holders are referred to the Indenture and such Act
      for a statement of such terms. The Securities are senior obligations of
      the Company initially limited to $250.0 million in aggregate principal
      amount, plus premiums and Liquidated Damages, if any, plus amounts, if
      any, sufficient to pay interest on outstanding Securities as set forth in
      Paragraph 2 hereof. Additional Notes may be issued from time to time
      subject to Section 4.09 of the Indenture. The Notes and any additional
      Notes subsequently issued would be treated as a single class for all
      purposes under the Indenture, including, without limitation, waivers,
      amendments, redemptions and offers to purchase.

            5. OPTIONAL REDEMPTION.

            The Company may redeem all or any of the Securities, in whole or in
      part, at any time on or after April 1, 2003 at the redemption prices
      (expressed as percentages of the principal amount) set forth in the
      immediately succeeding paragraph, plus accrued and unpaid interest thereon
      to the applicable redemption date.

            The redemption price as a percentage of the principal amount shall
      be as follows, if the Securities are redeemed during the twelve-month
      period beginning April 1 of the year indicated below:

              Year                                  Percentage
              ----                                  ----------

              2003 ................................  103.813%
              2004 ................................  102.542%
              2005 ................................  101.271%
              2006 and thereafter .................  100.000%
       
            Notwithstanding the foregoing, upon the occurrence at any time of a
      Change of Control, the Securities will be redeemable, at the option of the
      Company, in whole or in part, pursuant to the provisions of Section 3.08
      of the Indenture.

            6. MANDATORY OFFERS TO REPURCHASE; ASSET SALES.

            (a) Upon the occurrence of a Change of Control, the Company will be
      required to offer (a "Change of Control Offer") to purchase all
      outstanding Securities at a purchase price equal to 101% of the aggregate
      principal amount of 


                                      A-3


      such Securities, plus premium, Liquidated damages and accrued and unpaid
      interest, if any, to the date of purchase (the "Change of Control
      Payment"). The Change of Control Offer shall remain open for a period of
      20 Business Days after its commencement unless a longer offering period is
      required by law. No earlier than 30 days nor later than 40 days after the
      notice of the Change of Control Offer has been mailed (the "Change of
      Control Payment Date"), the Company shall deposit, to the extent lawful,
      with the Paying Agent an amount equal to the Change of Control Payment in
      respect of all Securities or portions thereof tendered by Holders. The
      Paying Agent shall promptly mail or deliver payment for all Securities
      tendered in the Change of Control Offer.

            A Holder of Securities may tender all or any portion of his
      Securities at his discretion by completing the form entitled "OPTION OF
      HOLDER TO ELECT PURCHASE" appearing on this Security. Any portion of
      Securities tendered must be in integral multiples of $1,000.

            (b) The Company is required to apply 100% of the Net Proceeds of any
      Asset Sale (including the sale of stock of any Subsidiary) first to repay
      Obligations or reduce commitments under the Credit Facilities, second to
      offer to redeem at par the Outstanding Notes and third to offer to redeem
      at par the Securities.

            7. NOTICE OF REDEMPTION. Notice of any redemption pursuant to
      Section 3.07 or 3.08 of the Indenture will be mailed by first class mail
      at least 30 days but not more than 60 days before the redemption date to
      each Holder whose Securities are to be redeemed at its registered address.
      Securities in denominations larger than $1,000 may be redeemed in part but
      only in whole multiples of $1,000, unless all of the Securities held by a
      Holder are to be redeemed. On and after the redemption date interest
      ceases to accrue on Securities or portions thereof called for redemption.

            8. 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. The Registrar
      and the Trustee may require a Holder, among other things, to furnish
      appropriate endorsements and transfer documents and the Company may
      require a Holder to pay any taxes and fees required by law or permitted by
      the Indenture. The Company need not exchange or register the transfer of
      any Security or portion of a Security selected for redemption, except the
      unredeemed portion of any Security being redeemed in part. Also, it need
      not exchange or register the transfer of any Securities for a period of 15
      days before the mailing of a Notice of Redemption and ending on the date
      of such mailing or during the period between a record date and the
      corresponding Interest Payment Date.

            9. PERSONS DEEMED OWNERS. The registered Holder of a Security may be
      treated as its owner for all purposes.

            10. AMENDMENTS AND WAIVERS. Subject to certain exceptions, the
      Indenture, the Securities or the Guarantee may be amended or supplemented
      and any existing Default under, or compliance with any provision of, the
      Indenture may be waived with the consent of the Holders of at least 51% in
      principal amount of the Securities then outstanding (including consents
      obtained in connection with a tender offer or exchange offer for
      Securities). Without the consent of any Holder, the Company and the
      Trustee may amend or supplement the Indenture or the Securities to cure
      any ambiguity, defect or inconsistency; to provide for uncertificated
      Securities in addition to or in place of certificated Securities; to
      comply with Section 5.01 of the Indenture; to make any change that would
      provide any additional rights or benefits to the Holders of the Securities
      or that does not adversely affect the legal rights under the Indenture of
      any such Holder; or to comply with requirements of the SEC in order to
      effect or maintain the qualification of the Indenture under the TIA.


                                      A-4


            Without the consent of each Holder affected, an amendment or waiver
      may not (with respect to any Securities held by a non-consenting Holder of
      Securities) (i) reduce the principal amount of Securities whose Holders
      must consent to an amendment, supplement or waiver, (ii) reduce the
      principal of or change the fixed maturity of any Security or alter the
      provisions with respect to the redemption or purchase price in connection
      with repurchases under Sections 3.07, 3.08, 4.10 or 4.11 of the Indenture,
      (iii) reduce the rate of or change the time for payment of interest on any
      Security, (iv) waive a Default or Event of Default in the payment of
      principal of or premium or Liquidated Damages, if any, or interest on the
      Securities or that resulted from a failure to comply with Sections 4.10 or
      4.11 of the Indenture (except a rescission of acceleration of the
      Securities by the Holders of at least 51% in aggregate principal amount of
      the Securities as provided in Section 6.02 of the Indenture), (v) make any
      Securities payable in money other than that stated in the Securities, (vi)
      make any change in Section 6.04 or 6.07 of the Indenture or this sentence,
      and or (vii) waive a redemption payment with respect to any Security.

            The right of any Holder to participate in any consent required or
      sought pursuant to any provision of the Indenture or this Security (and
      the obligation of the Company to obtain any such consent otherwise
      required from such Holder) may be subject to the requirement that such
      Holder shall have been the Holder of record of any Securities with respect
      to which such consent is required or sought as of a date identified by the
      Trustee in a notice furnished to Holders in accordance with the terms of
      the Indenture.

            11. DEFAULTS AND REMEDIES. Events of Default include: default in
      payment of interest or Liquidated Damages on the Securities for 30 days;
      default in payment of the principal or premium of any Security at
      maturity, or upon acceleration, redemption or otherwise; failure by the
      Company for 30 days after written notice to it from the Trustee, or after
      written notice to it and the Trustee from Holders of at least 30% in
      principal amount of the then outstanding Securities, to comply with any of
      its other agreements in the Indenture or the Securities; certain defaults
      under other Indebtedness; certain final judgments that remain undischarged
      for 60 days after being entered; certain events of bankruptcy or
      insolvency; and, except as permitted by the Indenture and the Securities,
      the Guarantees are held in any judicial proceeding to be unenforceable or
      invalid or otherwise cease for any reason to be in full force and effect
      with respect to any Guarantor or any Guarantor denies or disaffirms its
      obligations under its Guarantee. If an Event of Default occurs and is
      continuing, the Trustee or the Holders of at least 30% in principal amount
      of the then outstanding Securities may declare all the Securities to be
      immediately due and payable for an amount equal to 100% of the principal
      amount of the Securities plus premium and Liquidated Damages, if any, and
      accrued interest to the date of payment, 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 immediately without
      further action or notice. Holders 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
      Holders notice of any continuing Default or Event of Default (except a
      Default or an Event of Default in payment of principal, premium or
      Liquidated Damages, if any, or interest or that resulted from a failure to
      comply with Section 4.10 or 4.11 of the Indenture) if and so long as a
      committee of its Responsible Officers determines in good faith that
      withholding notice is in their interests. The Company must furnish an
      annual compliance certificate to the Trustee.

            12. TRUSTEE DEALINGS WITH COMPANY. The Trustee, in its individual or
      any other capacity, may make loans to, accept deposits from, and perform
      services for the Company or its Affiliates, and may otherwise deal with
      the Company or its Affiliates, as if it were not Trustee.

            13. NO RECOURSE AGAINST OTHERS. No director, officer, employee,
      incorporator or shareholder of the Company, as such, shall have any
      liability for any obligations of the Company under the Securities, this
      Indenture or the Guarantees or for any claim based on, in respect of, or
      by reason of, such obligations or their creation. Each

      Reference is hereby made to the Indenture, dated as of February 17, 1998
(the "Indenture"), between PRIMEDIA Inc., as issuer (the "Company"), and The
Bank of New York, as trustee. Capitalized terms used but not defined herein
shall have the meanings given to them in the Indenture.

      In connection with our proposed purchase of $____________ aggregate
principal amount of:

      (a)   |_| a beneficial interest in a Global Note, or

      (b)   |_| a Definitive Note, we confirm that:

      1. We understand that any subsequent transfer of the Notes or any interest
therein is subject to certain restrictions and conditions set forth in the
Indenture and the undersigned agrees to be bound by, and not to resell, pledge
or otherwise transfer the Notes or any interest therein except in compliance
with, such restrictions and conditions and the United States Securities Act of
1933, as amended (the "Securities Act").

      2. We understand that the offer and sale of the Notes have not been
registered under the Securities Act, and that the Notes and any interest therein
may not be offered or sold except as permitted in the following sentence. We
agree, on our own behalf and on behalf of any accounts for which we are acting
as hereinafter stated, that if we should sell the Notes or any interest therein,
we will do so only (A) to the Company or any subsidiary thereof, (B) in
accordance with Rule 144A under the Securities Act to a "qualified institutional
buyer" (as defined therein), (C) to an institutional "accredited investor" (as
defined below) that, prior to such transfer, furnishes (or has furnished on its
behalf by a U.S. broker-dealer) to you and to the Company a signed letter
substantially in the form of this letter and, if such transfer is in respect of
a principal amount of Notes, at the time of transfer of less than $100,000, an
Opinion of Counsel in form reasonably acceptable to the Company to the effect
that such transfer is in compliance with the Securities Act, (D) outside the
United States in accordance with Rule 904 of Regulation S under the Securities
Act, (E) pursuant to the provisions of Rule 144 under the Securities Act or (F)
pursuant to an effective registration statement under the Securities Act, and we
further agree to provide to any person purchasing the Definitive Note or
beneficial interest in a Global Note from us in a transaction meeting the
requirements of clauses (A) through (E) of this paragraph a notice advising such
purchaser that resales thereof are restricted as stated herein.

      3. We understand that, on any proposed resale of the Notes or beneficial
interest therein, we will be required to furnish to you and the Company such
certifications, legal opinions and other information as you and the Company may
reasonably require to confirm that the 


                                      D-1


proposed sale complies with the foregoing restrictions. We further understand
that the Notes purchased by us will bear a legend to the foregoing effect.

      4. We are an institutional "accredited investor" (as defined in Rule
501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act) and have
such knowledge and experience in financial and business matters as to be capable
of evaluating the merits and risks of our investment in the Notes, and we and
any accounts for which we are acting are each able to bear the economic risk of
our or its investment.

      5. We are acquiring the Notes or beneficial interest therein purchased by
us for our own account or for one or more accounts (each of which is an
institutional "accredited investor") as to each of which we exercise sole
investment discretion and we are acquiring the Notes for investment purposes and
not with a view to, or for offer or sale in connection with, any distribution in
violation of the Securities Act or other applicable securities law.

      You and the Company are entitled to rely upon this letter and are
irrevocably authorized to produce this letter or a copy hereof to any interested
party in any administrative or legal proceedings or official inquiry with
respect to the matters covered hereby.
