reasonably satisfactory to the Trustee stating that the issuance of the Private
Exchange Notes or the Unrestricted Notes, as the case may be, does not give rise

for exchange ("Registrar"), (b) Notes may be presented or surrendered for
payment ("Paying Agent") and (c) notices and demands to or upon the Company in
respect of the Notes and this Indenture may be served. The Registrar shall keep
a register of the Notes and of their transfer and exchange. The Company, upon
prior written notice to the Trustee, may have one or more co-Registrars and one
or more additional paying agents reasonably acceptable to the Trustee. The term
"Paying Agent" includes any additional Paying Agent. Neither the Company nor any
Affiliate of the Company may act as Paying Agent.

               The Company shall enter into an appropriate agency agreement with
any Agent not a party to this Indenture, which agreement shall incorporate the
provisions of the TIA and implement the provisions of this Indenture that relate
to such Agent. The Company shall notify the Trustee, in advance, of 

   38
                                      -38-

the name and address of any such Agent. If the Company fails to maintain a
Registrar or Paying Agent, or fails to give the foregoing notice, the Trustee
shall act as such and shall be entitled to appropriate compensation in
accordance with Section 7.07.

               The Company initially appoints the Trustee, who has an Affiliate
in New York with an office at 61 Broadway, 15th Floor, New York, NY 10006, as
Registrar, Paying Agent and agent for service of demands and notices in
connection with the Notes, until such time as either of such Persons has
resigned or a successor has been appointed. Any Paying Agent or Registrar may
resign upon 30 days' prior written notice to the Company.

               SECTION 2.04. Paying Agent To Hold Assets in Trust.

               The Company shall require each Paying Agent other than the
Trustee to agree in writing that, subject to Articles Ten and Eleven, each
Paying Agent shall hold in trust for the benefit of the Holders or the Trustee
all assets held by the Paying Agent for the payment of principal of, or interest
on, the Notes (whether such assets have been distributed to it by the Company or
any other obligor on the Notes), and the Company and the Paying Agent shall
notify the Trustee in writing of any Default by the Company (or any other
obligor on the Notes) in making any such payment. The Company at any time may
require a Paying Agent to distribute all assets held by it to the Trustee and
account for any assets disbursed and the Trustee may at any time during the
continuance of any payment Default, upon written request to a Paying Agent,
require such Paying Agent to distribute all assets held by it to the Trustee and
to account for any assets distributed. Upon distribution to the Trustee of all
assets that shall have been delivered by the Company to the Paying Agent, the
Paying Agent shall have no further liability for such assets.

               SECTION 2.05. Noteholder Lists.

               The Trustee shall preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
Noteholders. If the Trustee is not the Registrar, the Company shall furnish or
cause the Registrar to furnish to the Trustee as of each Record Date and before
each related Interest Payment Date and at such other times as the Trustee may
request in writing a list as of such date and in such form as the Trustee may
reasonably require of the names 

   39
                                      -39-

and addresses of Noteholders, which list may be conclusively relied upon by the
Trustee.

               SECTION 2.06. Transfer and Exchange.

               Subject to the provisions of Sections 2.15 and 2.16, when Notes
are presented to the Registrar or a co-Registrar with a request to register the
transfer of such Notes or to exchange such Notes for an equal principal amount
of Notes of other authorized denominations, the Registrar or co-Registrar shall
register the transfer or make the exchange as requested if its requirements for
such transaction are met; provided, however, that the Notes presented or
surrendered for registration of transfer or exchange shall be duly endorsed or
accompanied by a written instrument of transfer in form satisfactory to the
Company and the Registrar or co-Registrar, duly executed by the Holder thereof
or his attorney duly authorized in writing. To permit registrations of transfer
and exchanges, the Company shall issue and execute and the Trustee shall
authenticate Notes at the Registrar's or co-Registrar's request. No service
charge shall be made to a Noteholder for any registration of transfer or
exchange. The Company may require from such Noteholder 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 exchanges or transfers pursuant to Sections 2.10, 3.06,
4.15, 4.16 or 9.06, in which event the Company shall be responsible for the
payment of such taxes).

               The Registrar or co-Registrar shall not be required to register
the transfer of or exchange of any Note (i) during a period beginning at the
opening of business 15 days before the mailing of a notice of redemption of
Notes and ending at the close of business on the day of such mailing and (ii)
selected for redemption in whole or in part pursuant to Article Three, except
the unredeemed portion of any Note being redeemed in part.

               Any Holder of the Global Note shall, by acceptance of such Global
Note, agree that transfers of beneficial interests in such Global Notes may be
effected only through a book entry system maintained by the Holder of such
Global Note (or its agent) and that ownership of a beneficial interest in the
Note shall be required to be reflected in a book entry.

               SECTION 2.07. Replacement Notes.

   40
                                      -40-

               If a mutilated Note is surrendered to the Trustee or if the
Holder of a Note claims that the Note has been lost, destroyed or wrongfully
taken, the Company shall issue and execute and the Trustee shall authenticate a
replacement Note if the Trustee's requirements are met. If required by the
Trustee or the Company, such Holder must provide an affidavit of lost
certificate and an indemnity bond or other indemnity, sufficient in the judgment
of both the Company and the Trustee, to protect the Company, the Trustee or any
Agent from any loss which any of them may suffer if a Note is replaced. The
Company may charge such Holder for its reasonable, out-of-pocket expenses in
replacing a Note, including reasonable fees and expenses of the Trustee and
counsel, and the Trustee may charge the Company for the Trustee's reasonable
out-of-pocket expenses in replacing such Note. Every replacement Note shall
constitute an additional Obligation of the Company.

               SECTION 2.08. Outstanding Notes.

               Notes outstanding at any time are all the Notes that have been
authenticated by the Trustee except those canceled by it, those delivered to it
for cancellation and those described in this Section as not outstanding. Subject
to the provisions of Section 2.09, a Note does not cease to be outstanding
because the Company or any of its Affiliates holds the Note.

               If a Note is replaced pursuant to Section 2.07 (other than a
mutilated Note surrendered for replacement), it ceases to be outstanding unless
the Trustee receives proof satisfactory to it that the replaced Note is held by
a bona fide purchaser. A mutilated Note ceases to be outstanding upon surrender
of such Note and replacement thereof pursuant to Section 2.07.

               If on a Redemption Date or the Maturity Date, the Paying Agent
holds U.S. Legal Tender or U.S. Government Obligations sufficient to pay all of
the principal and interest due on the Notes payable on that date and is not
prohibited from paying such money to the Holders thereof pursuant to the terms
of this Indenture, then on and after that date such Notes cease to be
outstanding and interest on them ceases to accrue.

               SECTION 2.09. Treasury Notes.

               In determining whether the Holders of the required principal
amount of Notes have concurred in any direction, waiver, consent or notice,
Notes owned by the Company or any of 

   41
                                      -41-

its Affiliates shall be considered as though they are not outstanding, except
that for the purposes of determining whether the Trustee shall be protected in
relying on any such direction, waiver or consent, only Notes which a Trust
Officer of the Trustee actually knows are so owned shall be so considered. The
Company shall notify the Trustee, in writing, when it or any of its Affiliates
repurchases or otherwise acquires Notes, and of the aggregate principal amount
of such Notes so repurchased or otherwise acquired.

               SECTION 2.10. Temporary Notes.

               Until definitive Notes are ready for delivery, the Company may
prepare and the Trustee shall authenticate temporary Notes upon receipt of a
written order of the Company in the form of an Officers' Certificate. The
Officers' Certificate shall specify the amount of temporary Notes to be
authenticated and the date on which the temporary Notes are to be authenticated,
and shall direct the Trustee to authenticate such Notes and certify that all
conditions precedent to the issuance of such Notes contained herein have been
complied with. Temporary Notes shall be substantially in the form of definitive
Notes but may have variations that the Company and the Trustee consider
appropriate for temporary Notes. Without unreasonable delay, the Company shall
prepare and the Trustee shall authenticate upon receipt of a written order of
the Company pursuant to Section 2.02 definitive Notes in exchange for temporary
Notes.

               SECTION 2.11. Cancellation.

               The Company at any time may deliver Notes to the Trustee for
cancellation. The Registrar and the Paying Agent shall forward to the Trustee
any Notes surrendered to them for transfer, exchange or payment. The Trustee, or
at the direction of the Trustee, the Registrar or the Paying Agent, and no one
else, shall cancel and, at the written direction of the Company, shall dispose
of all Notes surrendered for registration of transfer, exchange, payment or
cancellation. Subject to Section 2.07, the Company may not issue new Notes to
replace Notes that it has paid or delivered to the Trustee for cancellation. If
the Company shall acquire any of the Notes, such acquisition shall not operate
as a redemption or satisfaction of the Indebtedness represented by such Notes
unless and until the same are surrendered to the Trustee for cancellation
pursuant to this Section 2.11.

   42
                                      -42-

               SECTION 2.12. Defaulted Interest.

               If the Company defaults in a payment of interest on the Notes, it
shall pay the defaulted interest, plus (to the extent lawful) any interest
payable on the defaulted interest to the Persons who are Holders on a subsequent
special record date, which date shall be the fifteenth day next preceding the
date fixed by the Company for the payment of defaulted interest or the next
succeeding Business Day if such date is not a Business Day. At least 15 days
before the subsequent special record date, the Company shall mail to each
Holder, with a copy to the Trustee, a notice that states the subsequent special
record date, the payment date and the amount of defaulted interest, and interest
payable on such defaulted interest, if any, to be paid.

               SECTION 2.13. CUSIP Numbers.

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

               SECTION 2.14. Deposit of Moneys.

               Prior to 10:00 a.m., New York City time, on each Interest Payment
Date and on the Maturity Date, the Company shall have deposited with the Paying
Agent in immediately available funds money sufficient to make cash payments, if
any, due on such Interest Payment Date or Maturity Date, as the case may be, in
a timely manner which permits the Paying Agent to remit payment to the Holders
on such Interest Payment Date or Maturity Date, as the case may be.

               SECTION 2.15. Book-Entry Provisions for Global Note.

               (a) The Global Note initially shall (i) be registered in the name
of the Depositary or the nominee of such 

   43
                                      -43-

Depositary, (ii) be delivered to the Trustee as custodian for such Depositary
and (iii) bear legends as set forth in Exhibit B.

               Members of, or participants in, the Depositary ("Agent Members")
shall have no rights under this Indenture with respect to any Global Note held
on their behalf by the Depositary, or the Trustee as its custodian, or under the
Global Note, and the Depositary may be treated by the Company, the Trustee and
any agent of the Company or the Trustee as the absolute owner of the Global Note
for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall
prevent the Company, the Trustee or any agent of the Company or the Trustee from
giving effect to any written certification, proxy or other authorization
furnished by the Depositary or impair, as between the Depositary and its Agent
Members, the operation of customary practices governing the exercise of the
rights of a holder of any Note.

               (b) Transfers of the Global Note shall be limited to transfers in
whole, but not in part, to the Depositary, its successors or their respective
nominees. Interests of beneficial owners in the Global Note may be transferred
or exchanged for Physical Notes in accordance with the rules and procedures of
the Depositary and the provisions of Section 2.16. In addition, Physical Notes
shall be transferred to all beneficial owners in exchange for their beneficial
interests in the Global Note if (i) the Depositary notifies the Company that it
is unwilling or unable to continue as Depositary for the Global Note and a
successor depositary is not appointed by the Company within 90 days of such
notice or (ii) an Event of Default has occurred and is continuing and the
Registrar has received a request from the Depositary to issue Physical Notes.

               (c) In connection with any transfer or exchange of a portion of
the beneficial interest in the Global Note to beneficial owners pursuant to
paragraph (b), the Registrar shall (if one or more Physical Notes are to be
issued) reflect on its books and records the date and a decrease in the
principal amount of the Global Note in an amount equal to the principal amount
of the beneficial interest in the Global Note to be transferred, and the Company
shall execute, and the Trustee shall authenticate and deliver, one or more
Physical Notes of like tenor and amount.

               (d) In connection with the transfer of the entire Global Note to
beneficial owners pursuant to paragraph (b), the Global Note shall be deemed to
be surrendered to the Trustee 

   44
                                      -44-

for cancellation, and the Company shall execute, and the Trustee shall
authenticate and deliver, to each beneficial owner identified by the Depositary
in exchange for its beneficial interest in the Global Note, an equal aggregate
principal amount of Physical Notes of authorized denominations.

               (e) Any Physical Note constituting a Restricted Security
delivered in exchange for an interest in the Global Note pursuant to paragraph
(b) or (c) shall, except as otherwise provided by paragraphs (a)(i)(x) and (c)
of Section 2.16, bear the legend regarding transfer restrictions applicable to
the Physical Notes set forth in Exhibit A(1).

               (f) The Holder of the Global Note may grant proxies and otherwise
authorize any person, including Agent Members and persons that may hold
interests through Agent Members, to take any action which a Holder is entitled
to take under this Indenture or the Notes.

               SECTION 2.16. Special Transfer Provisions.

               (a) Transfers to Non-QIB Institutional Accredited Investors and
Non-U.S. Persons. The following provisions shall apply with respect to the
registration of any proposed transfer of a Note constituting a Restricted
Security to any Institutional Accredited Investor which is not a QIB:

               (i) the Registrar shall register the transfer of any Note
        constituting a Restricted Security, whether or not such Note bears the
        Private Placement Legend, if (x) the requested transfer is after June
        18, 2000 and the transferor certifies that the Restricted Security was
        not acquired from the Company or Affiliate of the Company less than two
        years prior to the date of the proposed transfer or (y) in the case of a
        transfer to an Institutional Accredited Investor which is not a QIB, the
        proposed transferee has delivered to the Registrar a certificate
        substantially in the form of Exhibit C; and

              (ii) if the proposed transferor is an Agent Member holding a
        beneficial interest in the Global Note, upon receipt by the Registrar of
        (x) the certificate, if any, required by paragraph (i) above and (y)
        instructions given in accordance with the Depositary's and the
        Registrar's procedures,

whereupon (a) the Registrar shall reflect on its books and records the date and
(if the transfer does not involve a

   45
                                      -45-

transfer of outstanding Physical Notes) a decrease in the principal amount of
the Global Note in an amount equal to the principal amount of the beneficial
interest in the Global Note to be transferred, and (b) the Company shall execute
and the Trustee shall authenticate and deliver one or more Physical Notes of
like tenor and amount.

               (b) Transfers to QIBs. The following provisions shall apply with
respect to the registration of any proposed transfer of a Note constituting a
Restricted Security to a QIB:

               (i) the Registrar shall register the transfer if such transfer is
        being made by a proposed transferor who has checked the box provided for
        on the form of Note stating, or has otherwise advised the Company and
        the Registrar in writing, that the sale has been made in compliance with
        the provisions of Rule 144A to a transferee who has signed the
        certification provided for on the form of Note stating, or has otherwise
        advised the Company and the Registrar in writing, that it is purchasing
        the Note for its own account or an account with respect to which it
        exercises sole investment discretion and that it and any such account is
        a QIB within the meaning of Rule 144A, and is aware that the sale to it
        is being made in reliance on Rule 144A and acknowledges that it has
        received such information regarding the Company as it has requested
        pursuant to Rule 144A or has determined not to request such information
        and that it is aware that the transferor is relying upon its foregoing
        representations in order to claim the exemption from registration
        provided by Rule 144A; and

              (ii) if the proposed transferee is an Agent Member, and the Notes
        to be transferred consist of Physical Notes which after transfer are to
        be evidenced by an interest in the Global Note, upon receipt by the
        Registrar of instructions given in accordance with the Depositary's and
        the Registrar's procedures, the Registrar shall reflect on its books and
        records the date and an increase in the principal amount of the Global
        Note in an amount equal to the principal amount of the Physical Notes to
        be transferred, and the Trustee shall cancel the Physical Notes so
        transferred.

               (c) Private Placement Legend. Upon the registration of transfer,
exchange or replacement of Notes not bearing the Private Placement Legend, the
Registrar shall deliver Notes that do not bear the Private Placement Legend.
Upon the 

   46
                                      -46-

registration of transfer, exchange or replacement of Notes bearing the Private
Placement Legend, the Registrar shall deliver only Notes that bear the Private
Placement Legend unless (i) the circumstance contemplated by paragraph (a)(i)(x)
of this Section 2.16 exist or (ii) there is delivered to the Registrar an
Opinion of Counsel reasonably satisfactory to the Company and the Trustee to the
effect that neither such legend nor the related restrictions on transfer are
required in order to maintain compliance with the provisions of the Act.

               (d) General. By its acceptance of any Note bearing the Private
Placement Legend, each Holder of such a Note acknowledges the restrictions on
transfer of such Note set forth in this Indenture and in the Private Placement
Legend and agrees that it will transfer such Note only as provided in this
Indenture.

               The Registrar shall retain copies of all letters, notices and
other written communications received pursuant to Section 2.15 or this Section
2.16 for a period of three years. The Company shall have the right to inspect
and make copies of all such letters, notices or other written communications at
any reasonable time upon the giving of reasonable written notice to the
Registrar.

                                 ARTICLE THREE

                                   REDEMPTION

               SECTION 3.01. Notices to Trustee.

               If the Company elects to redeem Notes pursuant to Paragraph 6 of
the Notes, it shall notify both the Trustee and the Paying Agent in writing of
the Redemption Date and the principal amount of the Notes to be redeemed.

               The Company shall give each notice provided for in this Section
3.01 at least 45 days, but not more than 60 days, before the Redemption Date
(unless a shorter notice period shall be satisfactory to the Trustee, as
evidenced in a writing signed on behalf of the Trustee), together with an
Officers' Certificate and Opinion of Counsel stating that such redemption shall
comply with the conditions contained herein and in the Notes.

               SECTION 3.02. Selection of Notes To Be Redeemed.

   47
                                      -47-

               If fewer than all of the Notes are to be redeemed, the Trustee
shall select the Notes to be redeemed on a pro rata basis, by lot or in such
other fair and appropriate manner chosen at the discretion of the Trustee and,
if the Notes are listed on any national securities exchange, by a method that
complies with the requirements of such exchange; provided, however, that if
partial redemption is made with the proceeds of an Equity Offering prior to June
15, 2001, selection of the Notes or portions thereof for redemption shall be
made by the Trustee only on a pro rata basis or on as nearly a pro rata basis as
is practicable (subject to the applicable procedures of the Depositary) unless
such method is otherwise prohibited. The Trustee shall make the selection from
the Notes outstanding and not previously called for redemption and shall
promptly notify the Company in writing of the Notes selected for redemption and,
in the case of any Note selected for partial redemption, the principal amount
thereof to be redeemed. Notes in denominations of $1,000 or less may be redeemed
only in whole. The Trustee may select for redemption portions (equal to $1,000
or any integral multiple thereof) of the principal of Notes that have
denominations larger than $1,000. Provisions of this Indenture that apply to
Notes called for redemption also apply to portions of Notes called for
redemption.

               SECTION 3.03. Notice of Redemption.

               At least 30 days but not more than 60 days before a Redemption
Date, the Company shall mail or cause to be mailed a notice of redemption by
first-class mail, postage prepaid, to each Holder whose Notes are to be
redeemed, with a copy to the Trustee and any Paying Agent.

               Each notice for redemption shall identify the Notes to be
redeemed and shall state:

               (1) the Redemption Date;

               (2) the Redemption Price and the amount of accrued interest, if
        any, to be paid;

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

               (4) the subparagraph of the Notes pursuant to which such
        redemption is being made;

               (5) that Notes called for redemption must be surrendered to the
        Paying Agent to collect the Redemption Price plus accrued interest, if
        any;

   48
                                      -48-

               (6) that, unless the Company defaults in making the redemption
        payment, interest on Notes called for redemption ceases to accrue on and
        after the Redemption Date, and the only remaining right of the Holders
        of such Notes is to receive payment of the Redemption Price plus accrued
        interest, if any, upon surrender to the Paying Agent of the Notes
        redeemed;

               (7) if any Note is being redeemed in part, the portion of the
        principal amount (equal to $1,000 or any integral multiple thereof) of
        such Note to be redeemed and that, on or after the Redemption Date, and
        upon surrender of such Note, a new Note or Notes in the aggregate
        principal amount equal to the unredeemed portion thereof will be issued;
        and

               (8) if fewer than all the Notes are to be redeemed, the
        identification of the particular Notes (or portion thereof) to be
        redeemed, as well as the aggregate principal amount of Notes to be
        redeemed and the aggregate principal amount of Notes to be outstanding
        after such partial redemption.

               SECTION 3.04. Effect of Notice of Redemption.

               Once notice of redemption is mailed in accordance with Section
3.03, Notes called for redemption become due and payable on the Redemption Date
and at the Redemption Price plus accrued interest, if any. Upon surrender to the
Trustee or Paying Agent, such Notes called for redemption shall be paid at the
Redemption Price (which shall include accrued interest thereon to the Redemption
Date), but installments of interest, the maturity of which is on or prior to the
Redemption Date, shall be payable to Holders of record at the close of business
on the relevant record dates referred to in the Notes.

               SECTION 3.05. Deposit of Redemption Price.

               On or before the Redemption Date, the Company shall deposit with
the Paying Agent in immediately available funds U.S. Legal Tender sufficient to
pay the Redemption Price plus accrued interest, if any, of all Notes or portions
thereof to be redeemed on that date. The Paying Agent shall promptly return to
the Company any U.S. Legal Tender so deposited which is not required for that
purpose, except with respect to monies owed as obligations to the Trustee
pursuant to Article Seven.

   49
                                      -49-

               If the Company complies with the preceding paragraph, then,
unless the Company defaults in the payment of such Redemption Price plus accrued
interest, if any, interest on the Notes to be redeemed will cease to accrue on
and after the applicable Redemption Date, whether or not such Notes are
presented for payment.

               SECTION 3.06. Notes Redeemed in Part.

               Upon surrender of a Note that is to be redeemed in part, the
Company shall issue and execute, and the Trustee shall authenticate for the
Holder, a new Note or Notes equal in principal amount to the unredeemed portion

the respective organizational documents of each such Restricted Subsidiary and
the material rights (charter and statutory) and franchises of the Company and
each such Restricted Subsidiary; provided, however, that the Company shall not
be required to preserve, with respect to itself, any right or franchise and,
with respect to any of its Restricted Subsidiaries, any such existence, right or
franchise, if the Board of Directors of the Company shall determine in good
faith that the preservation thereof is no longer desirable in the conduct of the
business of the Company and its Restricted Subsidiaries, taken as a whole.

               SECTION 4.04. Payment of Taxes and Other Claims.

               The Company shall pay or discharge or cause to be paid or

penalties, interest and additions to taxes) levied or imposed upon it or any of
its Subsidiaries or its properties or any of its Subsidiaries' properties and

required to pay or discharge or cause to be paid or discharged any such tax,
assessment, charge or claim whose amount, applicability or validity is being or
will be contested in good faith by appropriate proceedings properly instituted
and diligently conducted for which adequate reserves, to the extent required

replacements, additions, betterments and improvements thereto and actively
conduct and carry on its business; provided, however, that nothing in this
Section 4.05 shall prevent the Company or any of its Restricted Subsidiaries
from discontinuing the operation and maintenance of any of its properties if
such discontinuance is, in the ordinary course of business or, in the good faith
judgment of the Board of Directors or other governing body of the Company or the
Restricted Subsidiary concerned, as the case may be, desirable in the conduct of
its businesses and is not disadvantageous in any material respect to the
Holders.

               (b) The Company shall maintain insurance (including appropriate
self-insurance) against loss or damage of the kinds that, in the good faith
judgment of the Company, are adequate and appropriate for the conduct of the

performed and fulfilled its Obligations under this Indenture and further
stating, as to each such Officer signing such certificate, that to the best of
such Officer's knowledge the Company during such period has kept, observed,
performed and fulfilled each and every such covenant and the Obligations

describe the Default or Event of Default and its status with 

   52
                                      -52-

particularity. The Officers' Certificate shall also notify the Trustee should
the Company elect to change the manner in which it fixes its fiscal year end.

               (b) The annual financial statements delivered pursuant to Section
4.08 shall be accompanied by a written report of the Company's independent
accountants (who shall be a firm of established national reputation) that in
conducting their audit of such financial statements nothing has come to their
attention that would lead them to believe that the Company has violated any
provisions of Article Four, Five or Six of this Indenture insofar as they relate
to accounting matters or, if any such violation has occurred, specifying the
nature and period of existence 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) (i) If any Default or Event of Default has occurred and is

respect to a claimed Event of Default under this Indenture or the Notes, the
Company shall deliver to the Trustee, at its address set forth in Section 11.02
hereof, by registered or certified mail or by telegram, telex or facsimile
transmission followed by hard copy by registered or certified mail an Officers'
Certificate specifying such event, notice or other action (including any action
the Company is taking or proposes to take in respect thereof) within five
Business Days of becoming aware of such occurrence.

               SECTION 4.07. Compliance with Laws.

               The Company shall, and shall cause each of its Subsidiaries to,
comply with all applicable statutes, rules, regulations, orders and restrictions
of the United States of America, all states and municipalities thereof, and of
any governmental department, commission, board, regulatory authority, bureau,
agency and instrumentality of the foregoing, in respect of the conduct of its
businesses and the ownership of its properties, except for such noncompliances
as are not in the aggregate reasonably likely to have a material adverse effect
on the business or financial condition of the Company and its Subsidiaries,
taken as a whole.

               SECTION 4.08. SEC Reports.

   53

documents and reports to be filed with the SEC pursuant to Sections 13 or 15(d)

the SEC pursuant to Section 13 or 15(d) of the Exchange Act. Upon qualification
of this Indenture under the TIA, the Company shall also comply with the
provisions of TIA Section 314(a).

               (b) At the Company's expense, the Company shall cause an annual

furnishing to stockholders.

               (c) The Company shall provide to any Holder any information

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 or extension law or any
usury law or other law that would prohibit or forgive the Company from paying
all or any portion of the principal of or interest on the Notes and as
contemplated herein, wherever enacted, now or at any time hereafter in force, or
which may affect the covenants or the performance of this Indenture; and (to the
extent that it may lawfully do so) the Company hereby expressly waives all
benefit or advantage of any such law, and covenants that it shall not hinder,
delay or impede the execution of any power herein granted to the Trustee, but
shall suffer and permit the execution of every such power as though no such law
had been enacted.

and (d) being referred to as a "Restricted Payment"), if at the time of such
Restricted Payment or immediately after giving effect thereto, (i) a Default or
an Event of Default shall have occurred and be continuing or (ii) the Company is
not able to incur at least $1.00 of additional Indebtedness (other than
Permitted Indebtedness) in compliance with Section 4.12 or (iii) the aggregate

and ending on the last day of the fiscal quarter immediately preceding the date
the Restricted Payment occurs (the "Reference Date") (treating such period as a
single accounting period); plus (B) 100% of the aggregate net cash proceeds
received by the Company from any Person (other than a Subsidiary of the Company)
from the issuance and sale of Qualified Capital Stock of the Company or from any
equity contribution from a holder of the Company's Capital Stock subsequent to
the Issue Date and on or prior to the Reference Date; plus (C) the principal
amount (or accreted amount as of such Reference Date) of any Indebtedness of the
Company or any Restricted Subsidiary of the Company incurred after the Issue
Date which has been converted into or exchanged for Qualified Capital Stock of
the Company (minus the amount of any cash or the fair market value (as
determined in good faith by the Board of Directors of the Company) of property
distributed by the Company or any Restricted Subsidiary of the

   55
                                      -55-

Company upon such conversion or exchange); plus (D) without duplication, the sum
of (1) the aggregate amount returned in cash on or with respect to Investments
(other than Permitted Investments) made subsequent to the Issue Date whether
through interest payments, principal payments, dividends or other distributions
or payments, (2) the net cash proceeds received by the Company or any of its
Restricted Subsidiaries from the disposition of all or any portion of such
Investments (other than to a Subsidiary of the Company) and (3) upon
redesignation of an Unrestricted Subsidiary as a Restricted Subsidiary, the fair
market value of such Subsidiary; provided, however, that the sum of clauses (1),
(2) and (3) above shall not exceed the aggregate amount of all such Investments
made subsequent to the Issue Date; plus (E) $20,000,000.

               Notwithstanding the foregoing, the provisions set forth in the
immediately preceding paragraph do not prohibit: (1) the payment of any dividend
or the consummation of any irrevocable redemption within 60 days after the date
of declaration of such dividend or the giving of such irrevocable redemption
notice if the dividend or redemption would have been permitted on the date of

and (6) the redemption of the Company's preferred stock purchase rights under
the Company's stockholder's rights plans in an aggregate amount not to exceed

preceding paragraph, amounts expended pursuant to clauses (1), (2)(ii), (3), (4)
and (5)(ii)(A) shall be included in such calculation.

               The amount of any non-cash Restricted Payment shall be the fair
market value, on the date such Restricted Payment is made, of the assets or
securities proposed to be transferred or issued by the Company or such
Restricted Subsidiary, as the case may be, pursuant to such Restricted Payment.
The fair market value of any non-cash Restricted Payment shall be determined by
the Board of Directors of the Company whose resolution with respect to the fair
market value of any Restricted Payment in excess of $5,000,000 shall be
delivered to the Trustee, such determination to be based upon an opinion or
appraisal issued by an accounting, appraisal or investment banking firm of
national standing if such fair market value exceeds $10,000,000. At least
semi-annually the Company shall deliver to the Trustee an Officers' Certificate
stating that all Restricted Payments made during the prior six month period were
permitted and setting forth the basis upon which the calculations required by
this covenant were computed, together with a copy of any opinion or appraisal
required by this Indenture.

               (a) The Company will not, and will not permit any of its
Restricted Subsidiaries to, directly or indirectly, enter into or permit to
exist any transaction or series of related transactions (including, without
limitation, the purchase, sale, lease or exchange of any property or the
rendering of any service) with, or for the benefit of, any of its Affiliates
(each an "Affiliate Transaction"), other than (x) Affiliate Transactions
permitted under paragraph (b) below and (y) Affiliate Transactions on terms that
are no less favorable than those that might reasonably have been obtained in a
comparable transaction at such time on an arm's-length basis from a Person that
is not an Affiliate of the Company or such Restricted Subsidiary. All Affiliate
Transactions (and each series of 

   57
                                      -57-

related Affiliate Transactions which are similar or part of a common plan)
involving aggregate payments or other property with a fair market value in
excess of $1,000,000 shall be approved by the Board of Directors of the Company
or such Restricted Subsidiary, as the case may be, such approval to be evidenced
by a Board Resolution stating that such Board of Directors has determined that
such transaction complies with the foregoing provisions. If the Company or any
Restricted Subsidiary of the Company enters into an Affiliate Transaction (or a
series of related Affiliate Transactions related to a common plan) that involves
an aggregate fair market value of more than $5,000,000 the Company or such
Restricted Subsidiary, as the case may be, shall, prior to the consummation
thereof, obtain a favorable opinion as to the fairness of such transaction or
series of related transactions to the Company or the relevant Restricted
Subsidiary, as the case may be, from a financial point of view, from an
Independent Financial Advisor and file the same with the Trustee.

               (b) The restrictions set forth in clause (a) above shall not
apply to (i) reasonable fees and compensation paid to and indemnity provided on
behalf of, officers, directors, employees or consultants of the Company or any
Restricted Subsidiary of the Company as determined in good faith by the
Company's Board of Directors or senior management; (ii) transactions exclusively
between or among the Company and any of its Wholly Owned Restricted Subsidiaries
or exclusively between or among such Wholly Owned Restricted Subsidiaries,
provided such transactions are not otherwise prohibited by this Indenture; (iii)
any agreement as in effect as of the Issue Date or any amendment thereto or any
transaction contemplated thereby (including pursuant to any amendment thereto)
in any replacement agreement thereto so long as any such amendment or
replacement agreement is not more disadvantageous to the Holders in any material
respect than the original agreement as in effect on the Issue Date; (iv)
advances and loans to employees for relocation, entertainment and travel
expenses, drawing accounts and other matters in the ordinary course of business;
(v) transactions with Annapurna Corporation aggregating not more than $500,000
in any fiscal year; and (vi) Restricted Payments permitted by this Indenture.

               SECTION 4.12. Limitation on Incurrence of Additional
                             Indebtedness.

               The Company will not, and will not permit any of its 

   58
                                      -58-

Restricted Subsidiaries to, directly or indirectly, create, incur, assume,
guarantee, acquire, become liable, contingently or otherwise, with respect to,
or otherwise become responsible for payment of (collectively, "incur") any
Indebtedness (other than Permitted Indebtedness); provided, however, that if no
Default or Event of Default shall have occurred and be continuing at the time of
or as a consequence of the incurrence of any such Indebtedness, the Company or
any Restricted Subsidiary may incur Indebtedness (including, without limitation,
Acquired Indebtedness), in each case if on the date of the incurrence of such
Indebtedness, after giving effect to the incurrence thereof, the Consolidated
Fixed Charge Coverage Ratio of the Company is greater than 2.25 to 1.0 if such
Indebtedness is incurred prior to June 15, 2000 and 2.50 to 1.0 thereafter.

               SECTION 4.13. Limitation on Dividend and Other Payment
                             Restrictions Affecting Subsidiaries.

               The Company will not, and will not cause or permit any of its
Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or
permit to exist or become effective any encumbrance or restriction on the
ability of any Restricted Subsidiary of the Company to (a) pay dividends or make
any other distributions on or in respect of its Capital Stock; (b) make loans or
advances or to pay any Indebtedness or other obligation owed to the Company or
any other Restricted Subsidiary of the Company; or (c) transfer any of its
property or assets to the Company or any other Restricted Subsidiary of the
Company, except for such encumbrances or restrictions existing under or by
reason of: (1) applicable law; (2) this Indenture; (3) customary non-assignment,
subletting or restriction on transfer or net worth provisions of any contract,
license or any lease governing a leasehold interest of any Restricted Subsidiary
of the Company; (4) any instrument governing Acquired Indebtedness, which
encumbrance or restriction is not applicable to any Person, or the properties or
assets of any Person, other than the Person or the properties or assets of the
Person so acquired; (5) agreements existing on the Issue Date to the extent and
in the manner such agreements are in effect on the Issue Date; (6) the Credit
Facility; (7) restrictions on the transfer of assets subject to any Lien
permitted under this Indenture imposed by the holder of such Lien; (8) any
agreement for the sale or disposition of the Capital Stock or assets of any
Subsidiary of the Company; 

   59
                                      -59-

provided, that such encumbrances and restrictions are only applicable to such
Subsidiary or assets, as applicable, and any such sale or disposition is made in
compliance with Section 4.16 to the extent applicable thereto; or (9) an
agreement governing Indebtedness incurred to Refinance the Indebtedness issued,
assumed or incurred pursuant to an agreement referred to in clause (2), (4), (5)
or (6) above; provided, however, that the provisions relating to such
encumbrance or restriction contained in any such Indebtedness are no less
favorable to the Company in any material respect as determined by the Board of
Directors of the Company in their reasonable and good faith judgment than the
provisions relating to such encumbrance or restriction contained in agreements
referred to in such clause (2), (4), (5) or (6).

               SECTION 4.14. Prohibition on Incurrence of Senior Subordinated
                             Debt.

               The Company shall not, directly or indirectly, incur or suffer to
exist Indebtedness that is senior in right of payment to the Notes and
subordinate in right of payment to any other Indebtedness of the Company.

               SECTION 4.15. Limitation on Change of Control.

               (a) Upon the occurrence of a Change of Control, each Holder shall
have the right to require that the Company purchase all or a portion of such
Holder's Notes pursuant to the offer described below (the "Change of Control
Offer"), at a purchase price equal to 101% of the principal amount thereof plus
accrued and unpaid interest to the date of purchase. However, the Company is not
required to make a Change of Control Offer if a third party makes a Change of
Control Offer that would be in compliance with the provisions described in this
Section 4.15 if it were made by the Company and such third party purchases (for
the consideration referred to in the immediate preceding sentence) the Notes
validly tendered and not withdrawn.

               (b) Within 30 days following the date upon which the Change of
Control occurred, the Company shall send, by first class mail, a notice to each
Holder, with a copy to the Trustee, which notice shall govern the terms of the
Change of Control Offer. The notice to the Holders shall contain all
instructions and materials necessary to enable such Holders to

   60
                                      -60-

tender Notes pursuant to the Change of Control Offer. Such notice shall state:

                (1) that the Change of Control Offer is being made pursuant to
        this Section 4.15 and that all Notes tendered will be accepted for
        payment;

                (2) the purchase price (including the amount of accrued
        interest) and the purchase date (which shall be no earlier than 30 days
        nor later than 45 days from the date such notice is mailed, other than
        as may be required by law) (the "Change of Control Payment Date");

                (3) that any Note not tendered will continue to accrue interest
        if interest is then accruing;

                (4) that, unless the Company defaults in making payment
        therefor, any Note 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 a Note purchased pursuant to a
        Change of Control Offer will be required to surrender the Note, with the
        form entitled "Option of Holder to Elect Purchase" on the reverse of the
        Note completed, to the Paying Agent at the address specified in the
        notice prior to the close of business on the third business day prior to
        the Change of Control Payment Date;

                (6) that Holders will be entitled to withdraw their election if
        the Paying Agent receives, not later than three Business Days 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 Notes the Holder delivered for purchase and a
        statement that such Holder is withdrawing his election to have such Note
        purchased; and

                (7) the circumstances and relevant facts regarding such Change
        of Control.

               On or before the Change of Control Payment Date, the Company
shall (i) accept for payment Notes or portions thereof tendered pursuant to the
Change of Control Offer, (ii) deposit with the Paying Agent U.S. Legal Tender
sufficient to pay the purchase price plus accrued interest, if any, of all Notes
or portions thereof so tendered and accepted and (iii) deliver to the Trustee
Notes so accepted together with an Officers' 

   61
                                      -61-

Certificate stating the Notes or portions thereof being purchased by the
Company. The Paying Agent shall promptly mail or deliver to the Holders of Notes
so accepted payment in an amount equal to the purchase price plus accrued
interest, if any, and the Company shall execute and issue, and the Trustee shall
promptly authenticate and mail or deliver to such Holders new Notes equal in
principal amount to any unpurchased portion of the Notes surrendered. Any Notes
not so accepted shall be promptly mailed or delivered by the Company to the
Holder thereof. The Company shall publicly announce the results of the Change of
Control Offer on or as soon as practicable after the Change of Control Payment
Date. For purposes of this Section 4.15, the Trustee shall act as the Paying
Agent.

               (c) If the Credit Facility is in effect, or any amounts are owing
thereunder, in either case at the time of the occurrence of the Change of
Control, prior to the mailing of the notice referred to in clause (b) above, but
in any event within 30 days following any Change of Control, the Company shall
(i) repay in full and terminate all commitments under the Indebtedness under the
Credit Facility and all other Senior Debt the terms of which require repayment
upon a Change of Control or offer to repay in full and terminate all commitments
under all Indebtedness under the Credit Facility and all other Senior Debt and
to repay the Indebtedness owed to, and terminate the commitments of, each lender
which has accepted such offer or (ii) obtain the requisite consents under the
Credit Facility and all such other Senior Debt to permit the repurchase of the
Notes as provided in this Section 4.15. The Company shall first comply with the
covenant in the immediately preceding sentence before it shall be required to
repurchase Notes pursuant to this Section 4.15; provided that the Company's
failure to comply with the covenant described in the immediately preceding
sentence shall constitute an Event of Default described in Section 6.01(3) and
not in Section 6.01(2).

               The Company will comply with the requirements of Rule 14e-1 under
the Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the
repurchase of Notes pursuant to a Change of Control Offer. To the extent that
the provisions of any securities laws or regulations conflict with this Section
4.15, the Company shall comply with the applicable securities laws and
regulations and shall not be deemed to have breached its obligations under this
Section 4.15 by virtue thereof.

               SECTION 4.16. Limitation on Asset Sales.

               (a) The Company will not, and will not permit any of its
Restricted Subsidiaries to, consummate an Asset Sale unless (i) the Company or
the applicable Restricted Subsidiary, as the case may be, receives consideration
at the time of such Asset Sale at least equal to the fair market value of the
assets sold or otherwise disposed of (as determined in good faith by the
Company's Board of Directors), (ii) at least 75% of the consideration received
by the Company or the Restricted Subsidiary, as the case may be, from such Asset
Sale shall be in the form of cash or Cash Equivalents and is received at the
time of such disposition; provided, that the amount of (x) any liabilities of
the Company or any Restricted Subsidiary (other than contingent liabilities and
liabilities of the Company that are by their terms subordinated to the Notes or
any guarantee thereof) that are assumed by the transferee of any such assets
pursuant to a novation agreement that releases the Company or such Restricted
Subsidiary from further liability and (y) any notes or other obligations
received by the Company or any such Restricted Subsidiary from such transferee
that are converted by the Company or such Restricted Subsidiary into cash or
Cash Equivalents (to the extent of the cash or Cash Equivalents received) within
365 days following the closing of such Asset Sale, will be deemed to be cash for
purposes of this provision; provided, further, that the 75% limitation referred
to above shall not apply to any sale, transfer or other disposition of assets in
which the cash portion of the consideration received therefor, determined in
accordance with the foregoing proviso, is equal to or greater than what the
after-tax net proceeds would have been had such transaction complied with the
aforementioned 75% limitation; and (iii) upon the consummation of an Asset Sale,
the Company shall apply, or cause such Restricted Subsidiary to apply, the Net
Cash Proceeds relating to such Asset Sale within 365 days of receipt thereof
either (A) to prepay any Senior Debt and, in the case of any Senior Debt under
any revolving credit facility, effect a permanent reduction in the availability
under such revolving credit facility if required by the terms of such revolving
credit facility, or prepay the Indebtedness of any Restricted Subsidiary of the
Company that was incurred in accordance with Section 4.12 and, in the case of
any such Indebtedness under any revolving credit facility, effect a permanent
reduction in the availability under such revolving credit facility if required
by the terms of such revolving credit facility, (B) to make an investment in
properties and assets that replace the properties and assets that were the
subject of such Asset Sale or in properties and assets (including Qualified
Capital Stock

   63
                                      -63-

of a Person which becomes a Restricted Subsidiary) that will be used in the
business of the Company and its Restricted Subsidiaries as existing on the Issue
Date or in businesses reasonably related or incidental thereto ("Replacement
Assets"), or (C) a combination of prepayment and investment permitted by the
foregoing clauses (iii)(A) and (iii)(B). On the 366th day after an Asset Sale or
such earlier date, if any, as the Board of Directors of the Company or of such
Restricted Subsidiary determines not to apply the Net Cash Proceeds relating to
such Asset Sale as set forth in clauses (iii)(A), (iii)(B) and (iii)(C) of the
next preceding sentence (each, a "Net Proceeds Offer Trigger Date"), such
aggregate amount of Net Cash Proceeds which have not been applied on or before
such Net Proceeds Offer Trigger Date as permitted in clauses (iii)(A), (iii)(B)
and (iii)(C) of the next preceding sentence (each a "Net Proceeds Offer Amount")
shall be applied by the Company or such Restricted Subsidiary to make an offer
to purchase (the "Net Proceeds Offer") on a date (the "Net Proceeds Offer
Payment Date") not less than 30 nor more than 45 days following the applicable
Net Proceeds Offer Trigger Date, from all Holders on a pro rata basis, that
amount of Notes equal to the Net Proceeds Offer Amount at a price equal to 100%
of the principal amount of the Notes to be purchased, plus accrued interest to
the date of purchase; provided, however, that if at any time any non-cash
consideration received by the Company or any Restricted Subsidiary of the
Company, as the case may be, in connection with any Asset Sale is converted into
or sold or otherwise disposed of for cash (other than interest received with
respect to any such non-cash consideration), then such conversion or disposition
shall be deemed to constitute an Asset Sale hereunder and the Net Cash Proceeds
thereof shall be applied in accordance with this covenant. The Company may defer
the Net Proceeds Offer until there is an aggregate unutilized Net Proceeds Offer
Amount equal to or in excess of $10,000,000 resulting from one or more Asset
Sales (at which time, the entire unutilized Net Proceeds Offer Amount, and not
just the amount in excess of $10,000,000, shall be applied as required pursuant
to this paragraph).

               In the event of the transfer of substantially all (but not all)
of the property and assets of the Company and its Restricted Subsidiaries as an
entirety to a Person in a transaction permitted under Section 5.01, the
successor corporation shall be deemed to have sold the properties and assets of
the Company and its Restricted Subsidiaries not so transferred for purposes of
this covenant, and shall comply with the provisions of this covenant with
respect to such deemed sale as if it were an Asset Sale. In addition, the fair

   64
                                      -64-

market value of such properties and assets of the Company or its Restricted
Subsidiaries deemed to be sold shall be deemed to be Net Cash Proceeds for
purposes of this covenant.

               Notwithstanding the two immediately preceding paragraphs, the
Company and its Restricted Subsidiaries will be permitted to consummate an Asset
Sale without complying with such paragraphs to the extent (i) at least 75% of
the consideration for such Asset Sale constitutes Replacement Assets and (ii)
such Asset Sale is for fair market value; provided, that any consideration not
constituting Replacement Assets received by the Company or any of its Restricted
Subsidiaries in connection with any Asset Sale permitted to be consummated under
this paragraph shall constitute Net Cash Proceeds subject to the provisions of
the two preceding paragraphs.

               (b) Each Net Proceeds Offer will be mailed to the record Holders
as shown on the register of Holders within 25 days following the Net Proceeds
Offer Trigger Date, with a copy to the Trustee. A Net Proceeds Offer shall
remain open for a period of 20 business days or such longer period as may be
required by law. The notice shall contain all instructions and materials
necessary to enable such Holders to tender Notes pursuant to the Net Proceeds
Offer and shall state the following terms:

                (1) that the Net Proceeds Offer is being made pursuant to
        Section 4.16 and that all Notes tendered will be accepted for payment;
        provided, however, that if the aggregate principal amount of Notes
        tendered in a Net Proceeds Offer plus accrued interest at the expiration
        of such offer exceeds the aggregate amount of the Net Proceeds Offer,
        the Company shall select the Notes to be purchased on a pro rata basis
        (based on amounts tendered) (with such adjustments as may be deemed
        appropriate by the Company so that only Notes in denominations of $1,000
        or multiples thereof shall be purchased);

                (2) the purchase price (including the amount of accrued
        interest) and the purchase date (which shall be no earlier than 30 days
        nor later than 60 days from the date such notice is mailed, other than
        as may be required by law) (the "Proceeds Purchase Date");

                (3) that any Note not tendered will continue to accrue interest
        if interest is then accruing;
   65
                                      -65-

                (4) that, unless the Company defaults in making payment
        therefor, any Note accepted for payment pursuant to the Net Proceeds
        Offer shall cease to accrue interest after the Proceeds Purchase Date;

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

                (6) that Holders will be entitled to withdraw their election if
        the Paying Agent receives, not later than three Business Days preceding
        the Proceeds Purchase Date, a telegram, telex, facsimile transmission or
        letter setting forth the name of the Holder, the principal amount of the
        Notes the Holder delivered for purchase and a statement that such Holder
        is withdrawing his election to have such Note purchased; and

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

               On or before the Proceeds Purchase Date, the Company shall (i)
accept for payment Notes or portions thereof tendered pursuant to the Net
Proceeds Offer which are to be purchased in accordance with item (b)(1) above,
(ii) deposit with the Paying Agent U.S. Legal Tender sufficient to pay the
purchase price of all Notes to be purchased and (iii) deliver to the Trustee
Notes so accepted together with an Officers' Certificate stating the Notes or
portions thereof being purchased by the Company. The Paying Agent shall promptly
mail to the Holders of Notes so accepted payment in an amount equal to the
purchase price plus accrued interest, if any, and the Company shall execute and
issue, and the Trustee shall promptly authenticate and mail or deliver to such
Holders new Notes equal in principal amount to any unpurchased portion of the
Notes surrendered. The Company shall publicly announce the results of the Net
Proceeds Offer on or as soon as practicable after the Proceeds Purchase Date.
For purposes of this Section 4.16, the Trustee shall act as the Paying Agent.

               If the aggregate purchase price of Notes tendered pursuant to the
Net Proceeds Offer is less than the Net Cash Proceeds allotted to the purchase
of the Notes, the Company may 

   66
                                      -66-

apply the remaining Net Cash Proceeds for general corporate purposes.

               The agreements governing certain outstanding Senior Debt of the
Company may require that the Company and its Subsidiaries apply all proceeds
from asset sales to repay in full outstanding obligations under such Senior Debt
prior to the application of such proceeds to repurchase outstanding Notes.

               The Company will comply with all applicable securities laws in
connection with any Net Proceeds Offer, including Rule l4e-1 under the Exchange
Act. To the extent that the provisions of any securities laws or regulations
conflict with the provisions of this Section 4.16, the Company shall comply with
the applicable securities laws and regulations and shall not be deemed to have
breached its obligations under this Section 4.16 by virtue thereof.

               SECTION 4.17. Limitation on Preferred Stock of Restricted
                             Subsidiaries.

               The Company shall not permit any of its Restricted Subsidiaries
to issue any Preferred Stock (other than to the Company or to a Wholly Owned
Restricted Subsidiary of the Company) or permit any Person (other than the
Company or a Wholly Owned Restricted Subsidiary of the Company) to own any
Preferred Stock of any Restricted Subsidiary of the Company.

               SECTION 4.18. Limitation on Liens.

               The Company will not, and will not cause or permit any of its
Restricted Subsidiaries to, directly or indirectly, create, incur, assume or
permit or suffer to exist any Liens of any kind against or upon any property or
assets of the Company or any of its Restricted Subsidiaries whether owned on the
Issue Date or acquired after the Issue Date, or any proceeds therefrom, or
assign or otherwise convey any right to receive income or profits therefrom, to
secure any Indebtedness, unless (i) in the case of Liens securing Indebtedness
that is expressly subordinate or junior in right of payment to the Notes, the
Notes are secured by a Lien on such property, assets or proceeds that is senior
in priority to such Liens and (ii) in all other cases, the Notes are equally and
ratably secured, except for (A) Liens existing as of the Issue Date to the

   67
                                      -67-

extent and in the manner such Liens are in effect on the Issue Date; (B) Liens
securing Senior Debt; (C) Liens securing the Notes; (D) Liens of the Company or
a Wholly Owned Restricted Subsidiary of the Company on assets of any Restricted
Subsidiary of the Company; (E) Liens securing Refinancing Indebtedness which is
incurred to Refinance any Indebtedness which has been secured by a Lien
permitted under this Indenture and which has been incurred in accordance with
the provisions of this Indenture; provided, however, that such Liens (x) are no
less favorable to the Holders and are not more favorable to the lienholders with
respect to such Liens than the Liens in respect of the Indebtedness being
Refinanced and (y) do not extend to or cover any property or assets of the
Company or any of its Restricted Subsidiaries not securing the Indebtedness so
Refinanced; and (F) Permitted Liens.

               SECTION 4.19. Conduct of Business.

               The Company and its Restricted Subsidiaries shall not engage in
any businesses which are not the same as or similar, reasonably related or
incidental to the businesses in which the Company and its Restricted
Subsidiaries are engaged on the Issue Date.

               SECTION 4.20. Limitation of Guarantees by Subsidiaries.

               The Company will not permit any Restricted Subsidiary, directly
or indirectly, by way of the pledge of any intercompany note or otherwise, to
assume, guarantee or in any other manner become liable with respect to any
Indebtedness of the Company or any other Subsidiary (other than (A) Indebtedness
and other obligations under the Credit Facility, (B) Permitted Indebtedness of a
Restricted Subsidiary, (C) Indebtedness under Currency Agreements in reliance on
clause (v) of the definition of Permitted Indebtedness or (D) Interest Swap
Obligations incurred in reliance on clause (iv) of the definition of Permitted
Indebtedness), unless, in any such case, such Restricted Subsidiary executes and
delivers a supplemental indenture to this Indenture providing a guarantee of
payment of the Notes by such Restricted Subsidiary (the "Guarantee").

               Notwithstanding the foregoing, any such Guarantee by a Restricted
Subsidiary of the Notes shall provide by its terms 

   68
                                      -68-

that it shall be automatically and unconditionally released and discharged,
without any further action required on the part of the Trustee or any Holder,
upon: (i) the unconditional release of such Restricted Subsidiary from its
liability in respect of the Indebtedness in connection with which such Guarantee
was executed and delivered pursuant to the preceding paragraph; or (ii) any sale
or other disposition (by merger or otherwise) to any Person which is not a
Restricted Subsidiary of the Company of all of the Company's Capital Stock in,
or all or substantially all of the assets of, such Restricted Subsidiary;
provided, that (a) such sale or disposition of such Capital Stock or assets is
otherwise in compliance with the terms of this Indenture and (b) such
assumption, guarantee or other liability of such Restricted Subsidiary has been
released by the holders of the other Indebtedness so guaranteed.

               SECTION 5.01. When Company May Merge, Etc.

               (a) The Company shall not, in a single transaction or series of
related transactions, consolidate or merge with or into any Person, or sell,
assign, transfer, lease, convey or otherwise dispose of (or cause or permit any
Restricted Subsidiary of the Company to sell, assign, transfer, lease, convey or
otherwise dispose of) all or substantially all of the Company's assets
(determined on a consolidated basis for the Company and the Company's Restricted
Subsidiaries) whether as an entirety or substantially as an entirety to any
Person unless: (i) either (1) the Company shall be the surviving or continuing
corporation or (2) the Person (if other than the Company) formed by such
consolidation or into which the Company is merged or the Person which acquires
by sale, assignment, transfer, lease, conveyance or other disposition the
properties and assets of the Company and of the Company's Restricted
Subsidiaries substantially as an entirety (the "Surviving Entity") (x) shall be
a corporation organized and validly existing under the laws of the United States
or any State thereof or the District of Columbia and (y) shall expressly assume,
by supplemental indenture (in form and substance satisfactory to the Trustee),
executed and delivered to the Trustee, the due and punctual payment of the
principal of, and premium, if any, and interest on all of the Notes and the

   69
                                      -69-

performance of every covenant of the Notes, this Indenture and the Registration
Rights Agreement on the part of the Company to be performed or observed; (ii)
immediately after giving effect to such transaction and the assumption
contemplated by clause (i)(2)(y) above (including giving effect to any
Indebtedness and Acquired Indebtedness incurred or anticipated to be incurred in
connection with or in respect of such transaction), the Company or such
Surviving Entity, as the case may be, (1) shall have a Consolidated Net Worth
equal to or greater than the Consolidated Net Worth of the Company immediately
prior to such transaction and (2) shall be able to incur at least $1.00 of
additional Indebtedness (other than Permitted Indebtedness) pursuant to Section
4.12; (iii) immediately before and immediately after giving effect to such
transaction and the assumption contemplated by clause (i)(2)(y) above
(including, without limitation, giving effect to any Indebtedness and Acquired
Indebtedness incurred or anticipated to be incurred and any Lien granted in
connection with or in respect of the transaction), no Default or Event of
Default shall have occurred or be continuing; and (iv) the Company or the

supplemental indenture comply with the applicable provisions of this Indenture
and that all conditions precedent in this Indenture relating to such transaction
have been satisfied.

               (b) For purposes of clause (a) above, the transfer (by lease,

transactions) of all or substantially all of the properties or assets of one or
more Restricted Subsidiaries of the Company, the Capital Stock of which
constitutes all or substantially all of the properties and assets of the
Company, shall be deemed to be the transfer of all or substantially all of the
properties and assets of the Company.

               SECTION 5.02. Successor Corporation Substituted.

               Upon any consolidation, combination or merger or any transfer of
all or substantially all of the assets of the Company in accordance with this
Article Five, in which the Company is not the continuing corporation, the
Surviving Entity formed by such consolidation or into which the Company is
merged or to which such conveyance, lease or transfer is made shall succeed to,
and be substituted for, and may exercise 

   70
                                      -70-

every right and power of, the Company under this Indenture and the Notes with
the same effect as if such surviving entity had been named as such, and
thereafter the predecessor corporation shall be relieved of all Obligations and
covenants under this Indenture and the Notes; provided that solely for the
purpose of calculating amounts described in clause (iii) of the first paragraph
of Section 4.10, any such Surviving Entity shall only be deemed to have
succeeded to and be substituted for the Company with respect to the period
subsequent to the effective time of this transaction (and the Company shall be
deemed to be the "Company" for such purposes for all prior periods).

                                   ARTICLE SIX

                              DEFAULT AND REMEDIES

               SECTION 6.01. Events of Default.

               An "Event of Default" is:

               (1) the failure to pay interest on any Notes when the same
        becomes due and payable and the default continues for a period of 30
        days (whether or not such payment shall be prohibited by Article Ten of
        this Indenture);

               (2) the failure to pay the principal on any Notes, when such
        principal becomes due and payable, at maturity, upon redemption or
        otherwise (including the failure to make a payment to purchase Notes
        tendered pursuant to a Change of Control Offer or a Net Proceeds Offer)
        (whether or not such payment shall be prohibited by Article Ten of this
        Indenture);

               (3) a default in the observance or performance of any other
        covenant or agreement contained in this Indenture which default
        continues for a period of 30 days after the Company receives written
        notice specifying the default (and demanding that such default be
        remedied) from the Trustee or the Holders of at least 25% of the
        outstanding principal amount of the Notes (except in the case of a
        default with respect to Section 5.01, which will constitute an Event of
        Default with such notice requirement but without such passage of time
        requirement);

               (4) the failure to pay at final maturity (giving effect to any
        applicable grace periods and any extensions 

   71
                                      -71-

        thereof) the principal amount of any Indebtedness of the Company or any
        Restricted Subsidiary of the Company and such failure continues for a
        period of 20 days or more, or the acceleration of the final stated
        maturity of any such Indebtedness (which acceleration is not rescinded,
        annulled or otherwise cured within 20 days of receipt by the Company or
        such Restricted Subsidiary of notice of any such acceleration) if the
        aggregate principal amount of such Indebtedness, together with the
        principal amount of any other such Indebtedness in default for failure
        to pay principal at final maturity or which has been accelerated, in
        each case with respect to which the 20-day period described above has
        passed, aggregates $15,000,000 or more at any time;

               (5) one or more judgments in an aggregate amount in excess of
        $15,000,000 shall have been rendered against the Company or any of its
        Significant Subsidiaries and such judgments remain undischarged, unpaid
        or unstayed for a period of 60 days after such judgment or judgments
        become final and non-appealable;

               (6) the Company or any of its Significant Subsidiaries (A)
        commences a voluntary case or proceeding under any Bankruptcy Law with
        respect to itself, (B) consents to the entry of a judgment, decree or
        order for relief against it in an involuntary case or proceeding under
        any Bankruptcy Law, (C) consents to the appointment of a Custodian of it
        or for substantially all of its property, (D) consents to or acquiesces
        in the institution of a bankruptcy or an insolvency proceeding against
        it, (E) makes a general assignment for the benefit of its creditors, or
        (F) takes any corporate action to authorize or effect any of the
        foregoing;

               (7) a court of competent jurisdiction enters a judgment, decree
        or order for relief in respect of the Company or any of its Significant
        Subsidiaries in an involuntary case or proceeding under any Bankruptcy
        Law, which shall (A) approve as properly filed a petition seeking
        reorganization, arrangement, adjustment or composition in respect of the
        Company or any of its Significant Subsidiaries, (B) appoint a Custodian
        of the Company or any of its Significant Subsidiaries or for
        substantially all of its property or (C) order the winding-up or
        liquidation of its affairs; and such judgment, decree or order shall
        remain unstayed and in effect for a period of 60 consecutive days; or

                                      -72-

               SECTION 6.02. Acceleration.

               (a) If an Event of Default (other than an Event of Default
specified in Section 6.01(6) or (7) with respect to the Company) occurs and is
continuing and has not been waived pursuant to Section 6.04, either the Trustee
or the Holders of at least 25% in aggregate principal amount of the Notes then
outstanding, by notice in writing to the Company and the Trustee specifying the
respective Event of Default and that it is a "notice of acceleration" (the
"Acceleration Notice"), may declare the entire principal amount of and accrued
interest on the Notes to be immediately due and payable, and the same (i) shall
become immediately due and payable or (ii) if there are any amounts outstanding
under the Credit Facility, shall become due and payable upon the first to occur
of an acceleration under the Credit Facility, or 5 Business Days after receipt
by the Company and the Representative under the Credit Facility of such
Acceleration Notice (but only if such Event of Default is then continuing). If
an Event of Default specified in Section 6.01(6) or (7) occurs with respect to
the Company, the principal amount of and accrued interest on the Notes shall
become and be immediately due and payable without any declaration or other act
on the part of the Trustee or any holder.

               (b) At any time after a declaration of acceleration with respect
to the Notes as described in the preceding paragraph, the Holders of a majority
in principal amount of the Notes may rescind and cancel such declaration and its
consequences (i) if the rescission would not conflict with any judgment or
decree, (ii) if all existing Events of Default have been cured or waived except
nonpayment of principal or interest that has become due solely because of the
acceleration, (iii) to the extent the payment of such interest is lawful,
interest on overdue installments of interest and overdue principal, which has
become due otherwise than by such declaration of acceleration, has been paid,
(iv) if the Company has paid the Trustee its reasonable compensation and
reimbursed the Trustee for its expenses, disbursements and advances and (v) in
the event of the cure or waiver of an Event of Default of the type described in
clause (6) or (7) of Section 6.01, the Trustee shall have received an Officers'
Certificate and an Opinion of Counsel (which opinion shall be subject to
customary qualifications and assumptions reasonably acceptable to the Trustee)
that such Event of Default has been cured or waived. No such rescission shall
affect any subsequent Default or impair any right consequent thereto.

               SECTION 6.03. Other Remedies.

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

               The Trustee may maintain a proceeding even if it does not possess
any of the Notes 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. No remedy is exclusive of any
other remedy. All available remedies are cumulative to the extent permitted by
law.

               SECTION 6.04. Waiver of Past Defaults.

               Subject to Sections 2.09, 6.07 and 9.02, the Holders of a
majority in principal amount of the outstanding Notes by notice to the Trustee
may waive any existing Default or Event of Default and its consequences, except
a Default in the payment of principal of or interest on any Note as specified in
clauses (1) and (2) of Section 6.01. When a Default or Event of Default is
waived, it is cured and ceases.

               SECTION 6.05. Control by Majority.

               Subject to Section 2.09, the Holders of a majority in principal
amount of the outstanding Notes 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, including, without limitation, any remedies
provided for in Section 6.03. Subject to Section 7.01, however, the Trustee may
refuse to follow any direction that the Trustee reasonably believes conflicts
with any law or this Indenture, that the Trustee determines may be unduly
prejudicial to the rights of another Holder, or that may involve the Trustee in
personal liability; provided that the Trustee may take any other action deemed
proper by the Trustee which is not inconsistent with such direction.

               SECTION 6.06. Limitation on Suits.

               A Holder may not pursue any remedy with respect to this Indenture
or the Notes unless:

   74
                                      -74-

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

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

               (3) such Holder or Holders offer to the Trustee indemnity
        reasonably satisfactory to the Trustee against any loss, liability or
        expense to be incurred in compliance with such request;

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

               (5) during such 60-day period the Holders of a majority in
        principal amount of the outstanding Notes do not give the Trustee a
        direction which, in the opinion of the Trustee, is inconsistent with the
        request.

               The foregoing limitations shall not apply to a suit instituted by
a Holder for the enforcement of the payment of principal and premium, if any, or
interest on such Note on or after the respective due dates set forth in such
Note (including upon acceleration thereof); provided that upon institution of
any proceeding or exercise of any remedy, such Holders provide the Trustee with
prompt written notice thereof.

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

               SECTION 6.07. Rights of Holders To Receive Payment.

               Notwithstanding any other provision of this Indenture, the right
of any Holder to receive payment of principal of and interest on a Note, on or
after the respective due dates expressed in such Note, 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 such Holder.

               SECTION 6.08. Collection Suit by Trustee.

               If an Event of Default in payment of principal or interest
specified in clause (1) or (2) of Section 6.01 occurs 

   75
                                      -75-

and is continuing, the Trustee may recover judgment in its own name and as
trustee of an express trust against the Company or any other obligor on the
Notes for the whole amount of principal and accrued interest remaining unpaid,
together with interest on overdue principal and, to the extent that payment of
such interest is lawful, interest on overdue installments of interest, in each
case at the rate per annum borne by the Notes, 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 may file such proofs of claim and other papers or
documents as may be necessary or advisable in order to have the claims of the
Trustee (including any claim for the reasonable compensation, expenses, taxes,
disbursements and advances of the Trustee, its agents and counsel) and the
Holders allowed in any judicial proceedings relating to the Company or any other
obligor upon the Notes, any of their respective creditors or any of their
respective property and shall be entitled and empowered to collect and receive
any monies or other property payable or deliverable on any such claims and to
distribute the same, and any Custodian in any such judicial proceedings 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, taxes, disbursements and advances of the Trustee, its
agent and counsel, and any other amounts due the Trustee under Section 7.07. The
Company's payment obligations under this Section 6.09 shall be secured in
accordance with the provisions of Section 7.07 hereunder. 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 Notes 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 or property pursuant to this
Article Six, it shall pay out the money in the following order:

   76
                                      -76-

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

               Second: subject to Article Ten, to Holders for amounts due and
        unpaid on the Notes for principal and interest, ratably, without
        preference or priority of any kind, according to the amounts due and
        payable on the Notes for principal and interest, respectively;

               Third: subject to Article Ten, to the Company or any other
        obligor on the Notes, as their interests may appear, or as a court of
        competent jurisdiction may direct.

               The Trustee, upon prior notice to the Company, may fix a record
date and payment date for any payment to Holders pursuant to this Section 6.10.

               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 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, or a suit by a Holder or Holders of more than 10% in
principal amount of the outstanding Notes.

               SECTION 6.12. Restoration of Rights and Remedies.

               If the Trustee or any Holder has instituted any proceeding to
enforce any right or remedy under this Indenture or any Note and such proceeding
has been discontinued or abandoned for any reason, or has been determined
adversely to the Trustee or to such Holder, then and in every such case the
Company, the Trustee and the Holders shall, subject to any determination in such
proceeding, be restored severally and respectively to their former positions
hereunder, and thereafter all rights and remedies of the Trustee and the Holders
shall continue as though no such proceeding had been instituted.

                                      -77-

                                  ARTICLE SEVEN

                                     TRUSTEE

               SECTION 7.01. Duties of Trustee.

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

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

                (1) The Trustee need perform only those duties as are
        specifically set forth in this Indenture and the TIA and no others and
        no covenants or obligations shall be implied in this Indenture against
        the Trustee.

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

               (c) Notwithstanding anything to the contrary herein contained,
the Trustee may not be relieved from liability for its own negligent action, its
own negligent failure to act, or its own willful misconduct, except that:

                (1) This paragraph does not limit the effect of paragraph (b) of
        this Section 7.01.

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

                (3) The Trustee shall not be liable with respect to any action
        it takes or omits to take in good faith in

   78
                                      -78-

        accordance with a direction received by it pursuant to Section 6.02,
        6.04 or 6.05.

               (d) No provision of this Indenture shall require the Trustee to
expend or risk its own funds or otherwise incur any financial liability in the
performance of any of its duties hereunder or in the exercise of any of its
rights or powers if it shall have reasonable grounds for believing that
repayment of such funds or adequate indemnity against such risk or liability is
not reasonably assured to it.

               (e) Every provision of this Indenture that in any way relates to
the Trustee is subject to paragraphs (a), (b), (c), (d) and (f) of this Section
7.01 and Section 7.02.

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

               SECTION 7.02. Rights of Trustee.

               Subject to Section 7.01:

               (a) The Trustee may rely and shall be fully protected in acting
        or refraining from acting upon 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.

               (b) Before the Trustee acts or refrains from acting, it may
        consult with counsel and may require an Officers' Certificate or an
        Opinion of Counsel, or both, which shall conform to Sections 11.04 and
        11.05. The Trustee shall not be liable for any action it takes or omits
        to take in good faith in reliance on such Officers' Certificate or
        Opinion of Counsel.

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

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

   79
                                      -79-

        or powers.

               (e) The Trustee shall not be bound to make any investigation into
        the facts or matters stated in any resolution, certificate, statement,
        instrument, opinion, notice, request, direction, consent, order, bond,
        debenture, or other paper or document, but the Trustee, in its
        discretion, may make such further inquiry or investigation into such
        facts or matters as it may see fit.

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

               (g) The Trustee may consult with counsel and the advice or
        opinion of such counsel as to matters of law shall be full and complete
        authorization and protection from liability in respect of any action
        taken, omitted or suffered by it hereunder in good faith and in
        accordance with the advice or opinion of such counsel.

               (h) The Trustee shall not be charged with knowledge of any
        Defaults or Events of Default unless either (1) a Trust Officer of the
        Trustee shall have actual knowledge of such Default or Event of Default
        or (2) written notice of such Default or Event of Default shall have
        been given to the Trustee by any Holder or by the Company or any other
        obligor on the Notes or any holder of Senior Debt or any Representative
        thereof.

               SECTION 7.03. Individual Rights of Trustee.

               The Trustee in its individual or any other capacity may become
the owner or pledgee of Notes and may otherwise deal with the Company, any
Subsidiary of the Company, or their respective 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 must comply with Sections 7.10 and 7.11.

               SECTION 7.04. Trustee's Disclaimer.

   80
                                      -80-

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

               SECTION 7.05. Notice of Default.

               If a Default or an Event of Default occurs and is continuing and
if it is known to the Trustee, the Trustee shall mail to each Holder notice of
the uncured Default or Event of Default within 90 days after such Default or
Event of Default becomes known to the Trustee. Except in the case of a Default
or an Event of Default in payment of principal of, or interest on, any Note, the
Trustee may withhold the notice if and so long as its Board of Directors, the
executive committee of its Board of Directors or a committee of its directors
and/or Trust Officers in good faith determines that withholding the notice is in
the interest of the Holders.

               SECTION 7.06. Reports by Trustee to Holders.

               Within 60 days after each May 15 following initial issuance, the
Trustee shall, to the extent that any of the events described in TIA Section
313(a) occurred within the previous twelve months, but not otherwise, mail to
each Holder a brief report dated as of such date that complies with TIA Section
313(a). The Trustee also shall comply with TIA Sections 313(b) and (c).

               A copy of each report at the time of its mailing to Holders shall
be mailed to the Company and filed with the SEC and each stock exchange, if any,
on which the Notes are listed.

               The Company shall promptly notify the Trustee in writing if the
Notes become listed on any stock exchange and the Trustee shall comply with TIA
Section 313(d).

               SECTION 7.07. Compensation and Indemnity.

               The Company shall pay to the Trustee from time to time reasonable
compensation for its services. The Trustee's compensation shall not be limited
by any law on compensation of a trustee of an express trust. The Company shall
reimburse the Trustee upon request for all reasonable out-of-pocket expenses
incurred or made by it in connection with the performance of its duties under
this Indenture. Such expenses shall include

   81
                                      -81-

the reasonable fees and expenses of the Trustee's agents and counsel.

               The Company shall indemnify the Trustee and its agents,
employees, officers, directors and shareholders for, and hold it harmless
against, any loss, liability or expense incurred by it except for such actions
to the extent caused by any negligence, bad faith or willful misconduct on its
part, arising out of or in connection with the administration of this trust
including the reasonable costs and expenses of defending itself against any
claim or liability in connection with the exercise or performance of any of its
rights, powers or duties hereunder. The Trustee shall notify the Company
promptly of any claim asserted against the Trustee for which it may seek
indemnity. Failure by the Trustee to so notify the Company shall not relieve the
Company of its obligations hereunder. At the Trustee's sole discretion, the
Company shall defend the claim and the Trustee shall provide reasonable
cooperation and may participate at the Company's expense in the defense.
Alternatively, the Trustee may at its option have separate counsel of its own
choosing and the Company shall pay the reasonable fees and expenses of such
counsel; provided that the Company will not be required to pay such fees and
expenses if it assumes the Trustee's defense, there is no conflict of interest
between the Company and the Trustee in connection with such defense as
reasonably determined by the Trustee and no Default or Event of Default has
occurred and is continuing. The Company need not pay for any settlement made
without its written consent, which consent shall not be unreasonably withheld.
The Company need not reimburse any expense or indemnify against any loss or
liability to the extent incurred by the Trustee which is attributable to its
negligence, bad faith or willful misconduct.

               To secure the Company's payment obligations in this Section 7.07,
the Trustee shall have a lien prior to the Notes on all assets or money held or
collected by the Trustee, in its capacity as Trustee, except assets or money
held in trust to pay principal of or interest on particular Notes.

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

               The obligations of the Company under this Section 7.07 and any
lien arising hereunder shall survive the 

   82
                                      -82-

resignation or removal of the Trustee, the discharge of the Company's
Obligations pursuant to Article Eight or the termination of this Indenture.

               SECTION 7.08. Replacement of Trustee.

               The Trustee may resign by so notifying the Company in writing,
such resignation to be effective upon the appointment of a successor Trustee.
The Holders of a majority in principal amount of the outstanding Notes may
remove the Trustee by so notifying the Company and the Trustee in writing and
may appoint a successor Trustee with the Company's consent which consent shall
not be unreasonably withheld. The Company may remove the Trustee if:

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

               (2) the Trustee is adjudged bankrupt or insolvent;

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

               (4) the Trustee becomes incapable of acting.

               If the Trustee resigns or is removed or if a vacancy exists in
the office of Trustee for any reason, the Company shall notify each Holder of
such event and shall promptly appoint a successor Trustee. Within one year after
the successor Trustee takes office, the Holders of a majority in principal
amount of the Notes may appoint a successor Trustee to replace the successor
Trustee appointed by the Company.

               A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Immediately after that,
the retiring Trustee shall transfer all property held by it as Trustee to the
successor Trustee, subject to the lien provided in Section 7.07, 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. A successor Trustee shall mail notice of its succession to each
Holder.

               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 outstanding Notes may
petition any court of competent jurisdiction for the appointment of a 


   83
                                      -83-

successor Trustee.

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

               Notwithstanding replacement of the Trustee pursuant to this
Section 7.08, the Company's obligations under Section 7.07 shall continue for
the benefit of the retiring Trustee.

               SECTION 7.09. Successor Trustee by Merger, Etc.

               If the Trustee consolidates with, merges or converts into, or
transfers all or substantially all of its corporate trust business (including
the trust created under this Indenture) to, another corporation or national
banking association, the resulting, surviving or transferee corporation without
any further act shall, if such resulting, surviving or transferee corporation is
otherwise eligible hereunder, be the successor Trustee; provided that such
corporation shall be otherwise qualified and eligible under this Article Seven.

               SECTION 7.10. Eligibility; Disqualification.

               This Indenture shall always have a Trustee who satisfies the
requirement of TIA Sections 310(a)(1), (2) and (5). The Trustee (or, in the case
of a corporation included in a bank holding company system, the related bank
holding company) shall have a combined capital and surplus of at least
$100,000,000 as set forth in its most recent published annual report of
condition. In addition, if the Trustee is a corporation included in a bank
holding company system, the Trustee, independently of such bank holding company,
shall meet the capital requirements of TIA Section 310(a)(2). The Trustee shall
comply with TIA Section 310(b); provided, however, that there shall be excluded
from the operation of TIA Section 310(b)(1) any indenture or indentures under
which other securities, or certificates of interest or participation in other

               SECTION 8.01. Termination of the Company's Obligations.

               The Company may terminate its obligations under the Notes and

in trust by the Company and thereafter repaid to the Company, as provided in
Section 8.05) have been delivered to the Trustee for cancellation and the
Company has paid all sums payable by it hereunder, or if:

               (a) either (i) pursuant to Article Three, the Company shall have
        given notice to the Trustee and mailed a notice of redemption to each
        Holder of the redemption of all of the Notes under arrangements
        satisfactory to the Trustee for the giving of such notice or (ii) all
        Notes have otherwise become due and payable hereunder;

               (b) the Company shall have irrevocably deposited or caused to be
        deposited with the Trustee or a trustee satisfactory to the Trustee,
        under the terms of an irrevocable trust agreement in form and substance
        satisfactory to the Trustee, as trust funds in trust solely for the
        benefit of the Holders for that purpose, U.S. Legal Tender in such
        amount as is sufficient without consideration of reinvestment of such
        interest, to pay principal of, premium, if any, and interest on the
        outstanding Notes to maturity or redemption; provided that the Trustee
        shall have been irrevocably instructed to apply such U.S. Legal Tender
        to the payment of said principal, premium, if any, and interest with
        respect to the Notes and, provided, further, that from and after the

   85
                                      -85-

        time of deposit, the money deposited shall not be subject to the rights
        of holders of Senior Debt pursuant to the provisions of Article Ten;

               (c) no Default or Event of Default with respect to this Indenture
        or the Notes shall have occurred and be continuing on the date of such
        deposit or shall occur as a result of such deposit and such deposit will
        not result in a breach or violation of, or constitute a default under,
        any other instrument to which the Company is a party or by which it is
        bound;

               (d) the Company shall have paid all other sums payable by it
        hereunder; and

               (e) the Company shall have delivered to the Trustee an Officers'
        Certificate and an Opinion of Counsel, each stating that all conditions
        precedent providing for the termination of the Company's Obligations
        under the Notes and this Indenture have been complied with. Such Opinion
        of Counsel shall also state that such satisfaction and discharge does
        not result in a default under the Credit Facility (if then in effect) or
        any other agreement or instrument then known to such counsel that binds
        or affects the Company.

               Notwithstanding the foregoing paragraph, the Company's
Obligations in Sections 2.05, 2.06, 2.07, 2.08, 4.01, 4.02, 7.07, 8.05 and 8.06
shall survive until the Notes are no longer outstanding pursuant to the last
paragraph of Section 2.08. After the Notes are no longer outstanding, the
Company's Obligations in Sections 7.07, 8.05 and 8.06 shall survive.

               After such delivery or irrevocable deposit, the Trustee upon
request shall acknowledge in writing the discharge of the Company's Obligations
under the Notes and this Indenture except for those surviving Obligations
specified above.

               SECTION 8.02. Legal Defeasance and Covenant Defeasance.

               (a) The Company may, at its option by Board Resolution of the
Board of Directors of the Company, at any time, elect to have either paragraph
(b) or (c) below be applied to all outstanding Notes upon compliance with the
conditions set forth in Section 8.03.

   86
                                      -86-

               (b) Upon the Company's exercise under paragraph (a) hereof of the
option applicable to this paragraph (b), the Company shall, subject to the
satisfaction of the conditions set forth in Section 8.03, be deemed to have been
discharged from its Obligations with respect to all outstanding Notes on the
date the conditions set forth below are satisfied (hereinafter, "Legal
Defeasance"). For this purpose, Legal Defeasance means that the Company shall be
deemed to have paid and discharged the entire Indebtedness represented by the
outstanding Notes, which shall thereafter be deemed to be "outstanding" only for
the purposes of Section 8.04 hereof and the other Sections of this Indenture
referred to in (i) and (ii) below, and to have satisfied all its other
Obligations under such Notes and this Indenture (and the Trustee, on demand of
and at the expense of the Company, shall execute proper instruments
acknowledging the same), and Holders of the Notes and any amounts deposited
under Section 8.03 hereof shall cease to be subject to any Obligations to, or
the rights of, any holder of Senior Debt under Article Ten, or otherwise, except
for the following provisions, which shall survive until otherwise terminated or
discharged hereunder: (i) the rights of Holders of outstanding Notes to receive
solely from the trust fund described in Section 8.04 hereof, and as more fully
set forth in such Section, payments in respect of the principal of, premium, if
any, and interest on such Notes when such payments are due, (ii) the Company's
Obligations with respect to such Notes under Article Two and Section 4.02
hereof, (iii) the rights, powers, trusts, duties and immunities of the Trustee
hereunder and the Company's Obligations in connection therewith and (iv) this
Article Eight. Subject to compliance with this Article Eight, the Company may
exercise its option under this paragraph (b) notwithstanding the prior exercise
of its option under paragraph (c) hereof.

               (c) Upon the Company's exercise under paragraph (a) hereof of the
option applicable to this paragraph (c), the Company shall, subject to the
satisfaction of the conditions set forth in Section 8.03 hereof, be released
from its Obligations under the covenants contained in Sections 4.10 through 4.20
and Article Five hereof with respect to the outstanding Notes on and after the
date the conditions set forth below are satisfied (hereinafter, "Covenant
Defeasance"), and the Notes shall thereafter be deemed not "outstanding" for the
purposes of any direction, waiver, consent or declaration or act of Holders (and
the consequences of any thereof) in connection with such covenants, but shall
continue to be deemed "outstanding" for all other purposes hereunder (it being
understood that such Notes shall not be deemed outstanding for 

   87
                                      -87-

accounting purposes) and Holders of the Notes and any amounts deposited under
Section 8.03 hereof shall cease to be subject to any Obligations to, or the
rights of, any holder of Senior Debt under Article Ten or otherwise. For this
purpose, such Covenant Defeasance means that, with respect to the outstanding
Notes, the Company may omit to comply with and shall have no liability in
respect of any term, condition or limitation set forth in any such covenant,
whether directly or indirectly, by reason of any reference elsewhere herein to
any such covenant or by reason of any reference in any such covenant to any
other provision herein or in any other document and such omission to comply
shall not constitute a Default or an Event or Default under Section 6.01(3)
hereof, but, except as specified above, the remainder of this Indenture and such
Notes shall be unaffected thereby. In addition, upon the Company's exercise
under paragraph (a) hereof of the option applicable to this paragraph (c),
subject to the satisfaction of the conditions set forth in Section 8.03 hereof,
those events described in Section 6.01 (except those events described in Section
6.01(1), (2), (6) and (7)) shall not constitute Events of Default.

               SECTION 8.03. Conditions to Legal Defeasance or Covenant
                             Defeasance.

               The following shall be the conditions to the application of
either Section 8.02(b) or 8.02(c) hereof to the outstanding Notes:

               In order to exercise either Legal Defeasance or Covenant
Defeasance:

               (a) the Company must irrevocably deposit with the Trustee, in
        trust, for the benefit of the Holders, U.S. Legal Tender or U.S.
        Government Obligations, or a combination thereof, in such amounts as
        will be sufficient, in the opinion of a nationally recognized firm of
        independent public accountants, to pay the principal of, premium, if
        any, and interest on the Notes on the stated date for payment thereof or
        on the applicable redemption date, as the case may be, of such principal
        or installment of principal of or interest on the Notes; provided that
        the Trustee shall have received an irrevocable written order from the
        Company instructing the Trustee to apply such U.S. Legal Tender or the
        proceeds of such U.S. Government Obligations to said payments with
        respect to the Notes;

   88
                                      -88-

               (b) in the case of an election under Section 8.02(b) hereof, the
        Company shall have delivered to the Trustee an Opinion of Counsel in the
        United States reasonably acceptable to the Trustee confirming that (A)
        the Company has received from, or there has been published by, the
        Internal Revenue Service a ruling or (B) since the date of this
        Indenture, there has been a change in the applicable United States
        federal income tax law, in either case to the effect that, and based
        thereon such Opinion of Counsel shall confirm that, the Holders of the
        Notes will not recognize income, gain or loss for United States federal
        income tax purposes as a result of such Legal Defeasance and will be
        subject to United States federal income tax on the same amounts, in the
        same manner and at the same times as would have been the case if such
        Legal Defeasance had not occurred;

               (c) in the case of an election under Section 8.02(c) hereof, the
        Company shall have delivered to the Trustee an Opinion of Counsel in the
        United States reasonably acceptable to the Trustee confirming that the
        Holders of the Notes will not recognize income, gain or loss for United
        States federal income tax purposes as a result of such Covenant
        Defeasance and will be subject to United States federal income tax on
        the same amounts, in the same manner and at the same times as would have
        been the case if such Covenant Defeasance had not occurred;

               (d) immediately after giving effect to such deposit on a pro
        forma basis, no Default or Event of Default with respect to the Notes
        shall have occurred and be continuing on the date of such deposit (other
        than a Default or Event of Default resulting from the incurrence of
        Indebtedness all or a portion of the proceeds of which will be used to
        defease the Notes pursuant to this Article Eight concurrently with such
        incurrence) or insofar as Sections 6.01(6) and 6.01(7) hereof are
        concerned, at any time in the period ending on the 91st day after the
        date of such deposit;

               (e) such Legal Defeasance or Covenant Defeasance shall not result
        in a breach or violation of or constitute a default under this Indenture
        (other than a Default or Event of Default resulting from the incurrence
        of Indebtedness, all or a portion of the proceeds of which will be used
        to defease the Notes) or any other material agreement or instrument to
        which the Company or any of 
   89
        its Subsidiaries is bound;

                (f) the Company shall have delivered to the Trustee an Officers'
        Certificate stating that the deposit was not made by the Company with
        the intent of preferring the Holders over any other creditors of the
        Company or with the intent of defeating, hindering, delaying or
        defrauding any other creditors of the Company;

                (g) the Company shall have delivered to the Trustee an Officers'
        Certificate and an Opinion of Counsel, each stating that all conditions
        precedent provided for or relating to the Legal Defeasance or the
        Covenant Defeasance have been complied with;

                (h) the Company shall have delivered to the Trustee an Opinion
        of Counsel to the effect that (A) the trust funds will not be subject to
        any rights of any holders of Senior Debt, including, without limitation,
        those arising under this Indenture and (B) after the 91st day following
        the deposit, the trust funds will not be subject to the effect of any
        applicable Bankruptcy Law;

                (i) The Company shall have paid or duly provided for payment of
        all amounts then due to the Trustee pursuant to Section 7.07 hereof; and

                (j) No such deposit will result in a Default under this
        Indenture (other than a Default or Event of Default resulting from the
        incurrence of Indebtedness, all or a portion of the proceeds of which
        will be used to defease the Notes) or a breach or violation of, or
        constitute a default under, any other instrument or agreement
        (including, without limitation, the Credit Facility) to which the
        Company or any of its subsidiaries is a party or by which it or its
        property is bound.

                Notwithstanding the foregoing, the Opinion of Counsel required
by clause (b) or (c) above need not be delivered if all Notes not theretofore
delivered to the Trustee for cancellation (x) have become due and payable, (y)
will become due and payable on the maturity date within one year or (z) are to
be called for redemption within one year under arrangements satisfactory to the
Trustee for the giving of notice of redemption by the Trustee in the name, and
at the expense, of the Company.


                SECTION 8.04. Application of Trust Money.

   90
                                      -90-


                The Trustee or Paying Agent shall hold in trust U.S. Legal
Tender or U.S. Government Obligations deposited with it pursuant to Article
Eight, and shall apply the deposited U.S. Legal Tender and the money from U.S.
Government Obligations in accordance with this Indenture to the payment of
principal of and interest on the Notes. The Trustee shall be under no obligation
to invest said U.S. Legal Tender or U.S. Government Obligations except as it may
agree with the Company.

                The Company shall pay and indemnify the Trustee against any tax,
fee or other charge imposed on or assessed against the U.S. Legal Tender or U.S.
Government Obligations deposited pursuant to Section 8.03 hereof or the
principal and interest received in respect thereof other than any such tax, fee
or other charge which by law is for the account of the Holders of the
outstanding Notes.

                Anything in this Article Eight to the contrary not withstanding,
the Trustee shall deliver or pay to the Company from time to time upon the
Company's request any U.S. Legal Tender or U. S. Government Obligations held by
it as provided in Section 8.03 hereof which, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written
certification thereof delivered to the Trustee, are in excess of the amount
thereof that would then be required to be deposited to effect an equivalent
Legal Defeasance or Covenant Defeasance.


                SECTION 8.05. Repayment to the Company

                Subject to Article Eight, the Trustee and the Paying Agent shall
promptly pay to the Company upon request any excess U.S. Legal Tender or U.S.
Government Obligations held by them at any time and thereupon shall be relieved
from all liability with respect to such money. The Trustee and the Paying Agent
shall pay to the Company upon request any money held by them for the payment of
principal or interest that remains unclaimed for two years; provided that the
Trustee or such Paying Agent, before being required to make any payment, may at
the expense of the Company cause to be published once in a newspaper of general
circulation in the City of New York or mail to each Holder entitled to such
money notice that such money remains unclaimed and that after a date specified
therein which shall be at least 30 days from the date of such publication or
mailing any unclaimed balance of such money then remaining will be repaid to the
Company. After payment to the Company, Noteholders entitled to such money must
look to the Company for payment as general creditors unless an applicable law

   91
                                      -91-


designates another Person.


                SECTION 8.06. Satisfaction and Discharge.

                This Indenture will be discharged and will cease to be of
further effect (except as to surviving rights of registration of transfer or
exchange of the Notes, as expressly provided for in this Indenture) as to all
outstanding Notes when (i) either (a) all the Notes theretofore authenticated
and delivered (except lost, stolen or destroyed Notes which have been replaced
or paid and Notes for whose payment money has theretofore been deposited in
trust or segregated and held in trust by the Company and thereafter repaid to
the Company or discharged from such trust) have been delivered to the Trustee
for cancellation or (b) all Notes not theretofore delivered to the Trustee for
cancellation have become due and payable and the Company has irrevocably
deposited or caused to be deposited with the Trustee funds in an amount
sufficient to pay and discharge the entire Indebtedness on the Notes not
theretofore delivered to the Trustee for cancellation, for principal of,
premium, if any, and interest on the Notes to the date of deposit together with
irrevocable instructions from the Company directing the Trustee to apply such
funds to the payment thereof at maturity or redemption, as the case may be; (ii)
the Company has paid all other sums payable under this Indenture by the Company;
and (iii) the Company has delivered to the Trustee an Officers' Certificate and
an Opinion of Counsel stating that all conditions precedent under this Indenture
relating to the satisfaction and discharge of this Indenture have been complied
with.


                SECTION 8.07. Reinstatement.

                If the Trustee or Paying Agent is unable to apply any U.S. Legal
Tender or U.S. Government Obligations in accordance with this Article Eight 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 Notes
shall be revived and reinstated as though no deposit had occurred pursuant to
Article Eight until such time as the Trustee or Paying Agent is permitted to
apply all such U.S. Legal Tender or U.S. Government Obligations in accordance
with Article Eight; provided that if the Company has made any payment of
interest on or principal of any Notes because of the reinstatement of its
Obligations, the Company shall be subrogated to the rights of the Holders of
such Notes to 

   92
                                      -92-


receive such payment from the U.S. Legal Tender or U.S. Government Obligations
held by the Trustee or Paying Agent.

Trustee, together, may amend or supplement this Indenture or the Notes without
notice to or consent of any Holder:

                (1) to cure any ambiguity, defect or inconsistency; provided
        that such amendment or supplement does not, in the opinion of the
        Trustee, adversely affect the rights of any Holder in any material
        respect;

                (2) to evidence the assumption of the Obligations hereunder by
        any successor corporation in connection with any transaction complying
        with Article Five;

                (3) to provide for uncertificated Notes in addition to or in
        place of certificated Notes;

                (4) to comply with any requirements of the SEC in order to

        or rights to the Holders or that does not adversely affect the rights of
        any Holder;

provided that the Company has delivered to the Trustee an Opinion of Counsel and
an Officers' Certificate stating that such amendment or supplement complies with
the provisions of this Section 9.01.

                SECTION 9.02. With Consent of Holders.

to any other Holders. Subject to Section 6.07, the Holder or Holders of a
majority in aggregate principal amount of the outstanding Notes may waive

                (4) make any changes in provisions concerning waivers of
        Defaults or Events of Default by Holders of the Notes or the rights of
        Holders to recover the principal of, interest on, premium, if any, or
        redemption payment with respect to, any Note;

                (5) make the principal of, or the interest on any Note payable
        with anything or in any manner other than as provided for in this
        Indenture and the Notes as in effect on the date hereof;

                (6) make any change in provisions of this Indenture protecting
        the right of each Holder to receive payment of principal of and interest
        on such Note on or after the due date thereof or to bring suit to
        enforce such payment, or permitting Holders of a majority in principal
        amount of Notes to waive Defaults or Events of Default;

                (7) after the Company's obligation to purchase Notes hereunder,
        amend, change or modify in any material respect the obligation of the
        Company to make and consummate a Change of Control Offer after the
        occurrence of an event which constitutes a Change of Control or make and
        consummate a Net Proceeds Offer with respect to any Asset Sale that has
        been consummated or modify any of the provisions or definitions with

                                      -94-


                (8) modify or change any provision of this Indenture or the
        related definitions affecting the subordination or ranking of the Notes
        in a manner which adversely affects the Holders.

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

                After an amendment, supplement or waiver under this Section 9.02
becomes effective, the Company shall mail to the Holders affected thereby a
notice briefly describing the amendment, supplement 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.

holder.


                SECTION 9.04. Compliance with TIA.

Notes shall comply with the TIA as then in effect.


                SECTION 9.05. Revocation and Effect of Consents.

                Until an amendment, waiver or supplement becomes effective, a
consent to it by a Holder is a continuing consent by the Holder and every
subsequent Holder of a Note or portion of a Note that evidences the same debt as
the consenting Holder's Note, even if notation of the consent is not made on any
Note. Subject to the following paragraph, any such Holder or subsequent Holder
may revoke the consent as to such Holder's Note or portion of such Note by
written notice to the Trustee or the Company received before the date on which
the Trustee receives an Officers' Certificate certifying that the Holders of the
requisite principal amount of Notes have consented (and not theretofore revoked
such consent) to the amendment, supplement or waiver.

   95
                                      -95-


                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, supplement or waiver, which record date shall be at least 30 days
prior to the first solicitation of such consent. If a record date is fixed, then
notwithstanding the last sentence 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 revoke any consent previously
given, whether or not such Persons continue to be Holders after such record
date. No such consent shall be valid or effective for more than 90 days after
such record date.

                After an amendment, supplement or waiver becomes effective, it
shall bind every Holder, unless it makes a change described in any of clauses
(1) through (8) of Section 9.02, in which case, the amendment, supplement or
waiver shall bind only each Holder of a Note who has consented to it and every
subsequent Holder of a Note or portion of a Note that evidences the same debt as
the consenting Holder's Note; provided that any such waiver shall not impair or
affect the right of any Holder to receive payment of principal of and interest
on a Note, on or after the respective due dates expressed in such Note, or to
bring suit for the enforcement of any such payment on or after such respective
dates without the consent of such Holder.

                SECTION 9.06. Notation on or Exchange of Notes.

                If an amendment, supplement or waiver changes the terms of a
Note, the Trustee may, at the written direction of the Company, require the
Holder of the Note to deliver it to the Trustee. The Trustee at the written
direction of the Company may place an appropriate notation on the Note about the
changed terms and return it to the Holder. Alternatively, if the Company or the
Trustee so determines, the Company in exchange for the Note shall issue and the
Trustee shall authenticate a new Note that reflects the changed terms. Any such
notation or exchange shall be made at the sole cost and expense of the Company.
Failure to make the appropriate notation or issue a new Note shall not affect
the validity and effect of such amendment, supplement or waiver.

                SECTION 9.07. Trustee To Sign Amendments, Etc.

                The Trustee shall execute any amendment, supplement or waiver
authorized pursuant to this Article Nine; provided 

   96
                                      -96-


that the Trustee may, but shall not be obligated to, execute any such amendment,
supplement or waiver which affects the Trustee's own rights, duties or
immunities under this Indenture. The Trustee shall be entitled to receive, if
requested, an indemnity reasonably satisfactory to it and to receive, and shall
be fully protected in relying upon, an Opinion of Counsel and an Officers'
Certificate each stating that the execution of any amendment, supplement or
waiver authorized pursuant to this Article Nine is authorized or permitted by
this Indenture. Such Opinion of Counsel shall not be an expense of the Trustee.


                                   ARTICLE TEN

                                  SUBORDINATION


                SECTION 10.01. Notes Subordinated to Senior Debt of the Company.

                The Company covenants and agrees and the Trustee and each Holder
of the Notes, by its acceptance thereof, likewise covenants and agrees, that all
Notes shall be issued subject to the provisions of this Article Ten; and the
Trustee and each Person holding any Note, whether upon original issue or upon
transfer, assignment or exchange thereof, accepts and agrees that the payment of
all Obligations on the Notes by the Company shall, to the extent and in the
manner herein set forth, be subordinated in right of payment to the prior
payment in full in cash of all Obligations on Senior Debt; that the
subordination is for the benefit of, and shall be enforceable directly by, the
holders of Senior Debt, and that each holder of Senior Debt whether now
outstanding or hereinafter created, incurred, assumed or guaranteed shall be
deemed to have acquired Senior Debt in reliance upon the covenants and
provisions contained in this Indenture and the Notes.

                SECTION 10.02. No Payment on Notes in Certain Circumstances.

                (a) If any default occurs and is continuing in the payment when
due, whether at maturity, upon any redemption, by declaration or otherwise, of
any principal of, interest on, unpaid drawings for letters of credit issued in
respect of, or 

   97
                                      -97-


regularly accruing fees with respect to, any Senior Debt (a "Payment Default"),
no payment of any kind or character shall be made by or on behalf of the Company
or any other Person on its or their behalf with respect to any Obligations on
the Notes or to acquire any of the Notes for cash or property or otherwise. In
addition, if any event of default other than a Payment Default (a "Non-payment
Default") occurs and is continuing with respect to any Designated Senior Debt,
as such event of default is defined in the instrument creating or evidencing
such Designated Senior Debt, permitting the holders of such Designated Senior
Debt then outstanding to accelerate the maturity thereof and if the
Representative for the respective issue of Designated Senior Debt gives written
notice of the Non-payment Default to the Trustee (a "Default Notice"), then,
unless and until all Non-payment Defaults have been cured or waived or have
ceased to exist or the Trustee receives notice from the Representative for the
respective issue of Designated Senior Debt terminating the Blockage Period (as
defined below), during the 180 days after the delivery of such Default Notice
(the "Blockage Period"), neither the Company nor any other Person on its behalf
shall (x) make any payment of any kind or character with respect to any
Obligations on the Notes or (y) acquire any of the Notes for cash or property or
otherwise. For all purposes of this Section 10.02(a), in no event will a
Blockage Period extend beyond 180 days from the date the payment on the Notes
was due and only one such Blockage Period may be commenced within any 360
consecutive days. No Non-payment Default which existed or was continuing on the
date of the commencement of any Blockage Period with respect to the Designated
Senior Debt shall be, or be made, the basis for commencement of a second
Blockage Period by the Representative of such Designated Senior Debt whether or
not within a period of 360 consecutive days, unless such Non-payment Default
shall have been cured or waived for a period of not less than 90 consecutive
days (it being acknowledged that any subsequent action or any breach of any
financial covenants for a period commencing after the date of commencement of
such Blockage Period, that in either case, would give rise to a Non-payment
Default pursuant to any provisions under which a Non-payment Default previously
existed or was continuing shall constitute a new Non-payment Default for this
purpose).

                (b) In the event that, notwithstanding the foregoing, any
payment shall be received by the Trustee or any Holder when such payment is
prohibited by Section 10.02(a), such payment shall be held in trust for the
benefit of, and shall be paid over or delivered to, the holders of Senior Debt
(pro rata to such holders on the basis of the respective amount 

   98
                                      -98-


of Senior Debt held by such holders) or their respective Representatives, as
their respective interests may appear. The Trustee shall be entitled to rely on
information regarding amounts then due and owing on the Senior Debt, if any,
received from the holders of Senior Debt (or their Representatives) or, if such
information is not received from such holders or their Representatives, from the
Company and only amounts included in the information provided to the Trustee
shall be paid to the holders of Senior Debt.

                Nothing contained in this Article Ten shall limit the right of
the Trustee or the Holders of Notes to take any action to accelerate the
maturity of the Notes pursuant to Section 6.02 or to pursue any rights or
remedies hereunder; provided that all Senior Debt thereafter due or declared to
be due shall first be paid in full in cash or Cash Equivalents before the
Holders are entitled to receive any payment of any kind or character with
respect to the Obligations on the Notes.


                SECTION 10.03. Payment Over of Proceeds Upon Dissolution, Etc.

                (a) Upon any payment or distribution of assets of the Company of
any kind or character, whether in cash, property or securities, to creditors
upon any total or partial liquidation, dissolution, winding-up, reorganization,
assignment for the benefit of creditors or marshaling of assets of the Company,
or in a bankruptcy, reorganization, insolvency, receivership or similar
proceeding relating to the Company or its property, whether voluntary or
involuntary, all Obligations with respect to all Senior Debt shall first be paid
in full, in cash, or such payment has been duly provided for to the satisfaction
of the holders of Senior Debt, before any payment or distribution of any kind or
character is made on account of any Obligations on the Notes, or for the
acquisition of any of the Notes for cash or property or otherwise; and until all
such Obligations with respect to all Senior Debt are paid in full in cash, any
distribution to which the Holders of the Notes would be entitled but for the
subordination provisions will be made to the holders of Senior Debt as their
interests may appear. Upon any such dissolution, winding-up, liquidation,
reorganization, bankruptcy, insolvency, receivership or similar proceeding or
assignment for the benefit of creditors or marshaling of assets, any payment or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities, to which the Holders of the Notes or the Trustee under
this Indenture would be entitled, except for the 

   99
                                      -99-


provisions hereof, shall be paid by the Company or by any receiver, trustee in
bankruptcy, liquidating trustee, agent or other person making such payment or
distribution, or by the Holders of the Notes or by the Trustee under this
Indenture if received by them, directly to the holders of Senior Debt (pro rata
to such holders on the basis of the respective amounts of Senior Debt held by
such holders) or their respective Representatives, or to the trustee or trustees
under any indenture pursuant to which any of such Senior Debt may have been
issued, as their respective interests may appear, for application to the payment
of Senior Debt remaining unpaid until all such Senior Debt has been paid in full
in cash or Cash Equivalents after giving effect to any concurrent payment,
distribution or provision therefor to or for the holders of Senior Debt.

                (b) To the extent any payment of Senior Debt (whether by or on
behalf of the Company, as proceeds of security or enforcement of any right of
setoff or otherwise) is declared to be fraudulent or preferential, set aside or
required to be paid to any receiver, trustee in bankruptcy, liquidating trustee,
agent or other similar person under any bankruptcy, insolvency, receivership,
fraudulent conveyance or similar law, then, if such payment is recovered by, or
paid over to, such receiver, trustee in bankruptcy, liquidating trustee, agent
or other similar person, the Senior Debt or part thereof originally intended to
be satisfied shall be deemed to be reinstated and outstanding as if such payment
had not occurred.

                (c) In the event that, notwithstanding the foregoing, any
payment or distribution of assets of the Company of any kind or character,
whether in cash, property or securities, shall be received by the Trustee or any
Holder when such payment or distribution is prohibited by Section 10.03(a), such
payment or distribution shall be held in trust for the benefit of, and shall be
paid over or delivered to, the holders of Senior Debt (pro rata to such holders
on the basis of the respective amount of Senior Debt held by such holders) or
their respective Representatives, or to the trustee or trustees under any
indenture pursuant to which any of such Senior Debt may have been issued, as
their respective interests may appear, for application to the payment of Senior
Debt remaining unpaid until all such Senior Debt has been paid in full in cash
or Cash Equivalents, after giving effect to any concurrent payment, distribution
or provision therefor to or for the holders of such Senior Debt.

                SECTION 10.04. Payments May Be Paid Prior to Dissolution.

                Nothing contained in this Article Ten or elsewhere in this
Indenture shall prevent (i) the Company, except under the conditions described
in Sections 10.02 and 10.03, from making payments at any time for the purpose of
making payments of principal of and interest on the Notes, or from depositing
with the Trustee any moneys for such payments, or (ii) in the absence of actual
knowledge of the Trustee that a given payment would be prohibited by Section
10.02 or 10.03, the application by the Trustee of any moneys deposited with it
for the purpose of making such payments of principal of and interest on the
Notes to the Holders entitled thereto unless at least one Business Day prior to
the date upon which such payment would otherwise become due and payable, the
Trustee shall have received the written notice provided for in Section 10.02(a)
or in Section 10.07 (provided that, notwithstanding the foregoing, such
application shall otherwise be subject to the provisions of the first sentence
of Section 10.02(a) and Section 10.03). The Company shall give prompt written
notice to the Trustee of any dissolution, winding-up, liquidation or
reorganization of the Company.


                SECTION 10.05. Subrogation.

                Subject to the payment in full in cash or Cash Equivalents of
all Senior Debt, the Holders of the Notes shall be subrogated to the rights of
the holders of Senior Debt to receive payments or distributions of cash,
property or securities of the Company applicable to the Senior Debt until the
Notes shall be paid in full; and, for the purposes of such subrogation, no such
payments or distributions to the holders of the Senior Debt by or on behalf of
the Company or by or on behalf of the Holders by virtue of this Article Ten
which otherwise would have been made to the Holders shall, as between the
Company and the Holders of the Notes, be deemed to be a payment by the Company
to or on account of the Senior Debt, it being understood that the provisions of
this Article Ten are and are intended solely for the purpose of defining the
relative rights of the Holders of the Notes, on the one hand, and the holders of
the Senior Debt, on the other hand.

                If any payment or distribution to which the Holders would
otherwise have been entitled but for the provisions of this Article Ten shall
have been applied, pursuant to the provisions of this Article Ten, to the
payment of amounts payable under the Senior Debt, then the Holders shall be

   101
                                     -101-


entitled to receive from the holders of such Senior Debt any payments or
distributions received by such holders of Senior Debt in excess of the amount
sufficient to pay all amounts payable under or in respect of the Senior Debt in
full in cash or Cash Equivalents.

                SECTION 10.06. Obligations of the Company Unconditional.

                Nothing contained in this Article Ten or elsewhere in this
Indenture or in the Notes is intended to or shall impair, as among the Company,
its creditors other than the holders of Senior Debt, and the Holders of the
Notes, the obligation of the Company, which is absolute and unconditional, to
pay to the Holders of the Notes the principal of and any interest on the Notes
as and when the same shall become due and payable in accordance with their
terms, or is intended to or shall affect the relative rights of the Holders of
the Notes and creditors of the Company other than the holders of the Senior
Debt, nor shall anything herein or therein prevent the Holder of any Note or the
Trustee on its behalf from exercising all remedies otherwise permitted by
applicable law upon default under this Indenture, subject to the rights, if any,
in respect of cash, property or securities of the Company received upon the
exercise of any such remedy.

                SECTION 10.07. Notice to Trustee; Rights of Trustee and Paying
                               Agent.

                The Company shall give prompt written notice to the Trustee of
any fact known to the Company which would prohibit the making of any payment to
or by the Trustee in respect of the Notes pursuant to the provisions of this
Article Ten. Regardless of anything to the contrary contained in this Article
Ten or elsewhere in this Indenture, neither the Trustee nor any Paying Agent
shall be charged with knowledge of the existence of any default or event of
default with respect to any Senior Debt or of any other facts which would
prohibit the making of any payment to or by the Trustee or any Paying Agent
unless and until a Trust Officer of the Trustee shall have received at least two
Business Days before a payment is required to be made, notice in writing from
the Company, or from a holder of Senior Debt or a Representative therefor, and,
prior to the receipt of any such written notice, the Trustee shall be entitled
to assume (in the absence of actual knowledge of a Trust Officer to the
contrary) that no such facts exist.

   102
                                     -102-


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

                SECTION 10.08. Reliance on Judicial Order or Certificate of
                               Liquidating Agent.

                Upon any payment or distribution of assets of the Company
referred to in this Article Ten, the Trustee, subject to the provisions of
Article Seven hereof, and the Holders of the Notes shall be entitled to rely
upon any order or decree made by any court of competent jurisdiction in which
bankruptcy, dissolution, winding-up, liquidation or reorganization proceedings
are pending, or upon certificate of the receiver, trustee in bankruptcy,
liquidating trustee, agent or other person making such payment or distribution,
delivered to the Trustee or the Holders of the Notes, for the purpose of
ascertaining the Persons entitled to participate in such distribution, the
holders of the Senior Debt and other Indebtedness of the Company, the amount
thereof or payable thereon, the amount or amounts paid or distributed thereon
and all other facts pertinent thereto or to this Article Ten.

                SECTION 10.09. Trustee's Relation to Senior Debt.

                The Trustee and any agent of the Company or the Trustee shall be
entitled to all the rights set forth in this Article Ten with respect to any
Senior Debt which may at any time be held by it in its individual or any other
capacity to the same extent as any other holder of Senior Debt and nothing in
this Indenture shall deprive the Trustee or any such agent of any of its rights
as such holder.

                With respect to the holders of Senior Debt, the Trustee
undertakes to perform or to observe only such of its covenants and Obligations
as are specifically set forth in this 

   103
                                     -103-


Article Ten, and no implied covenants or Obligations with respect to the holders
of Senior Debt shall be read into this Indenture against the Trustee. The
Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior
Debt and shall not be liable to any such holders if the Trustee shall pay over
or distribute to or on behalf of Holders or the Company or any other person
money or assets to which any holders of Senior Debt shall be entitled by virtue
of this Article Ten, except if such payment is made as a result of willful
misconduct or gross negligence of the Trustee.

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


                SECTION 10.10. Subordination Rights Not Impaired by Acts or
                               Omissions of the Company or Holders of Senior 
                               Debt.

                No right of any present or future holders of any Senior Debt to
enforce subordination as provided herein shall at any time in any way be
prejudiced or impaired by any act or failure to act on the part of the Company
or by any act or failure to act, in good faith, by any such holder, or by any
noncompliance by the Company with the terms of this Indenture, regardless of any
knowledge thereof which any such holder may have or otherwise be charged with.

                Without in any way limiting the generality of the foregoing
paragraph, the holders of Senior Debt may, at any time and from time to time,
without the consent of or notice to the Trustee, without incurring
responsibility to the Trustee or the Holders of the Notes and without impairing
or releasing the subordination provided in this Article Ten or the obligations
hereunder of the Holders of the Notes to the holders of the Senior Debt, do any
one or more of the following: (i) change the manner, place or terms of payment
or extend the time of payment of, or renew or alter, Senior Debt, or otherwise
amend or supplement in any manner Senior Debt, or any instrument evidencing the
same or any agreement under which Senior Debt is outstanding; (ii) sell,
exchange, release or otherwise deal with any property pledged, mortgaged or
otherwise securing Senior Debt; (iii) release any Person liable in any manner
for the payment or collection of Senior Debt; and (iv) exercise or refrain from
exercising any rights against the Company and any other Person.

                SECTION 10.11. Noteholders Authorize Trustee To Effectuate
                               Subordination of Notes.

                Each Holder of Notes by its acceptance of them authorizes and
expressly directs the Trustee on its behalf to take such action as may be
necessary or appropriate to effectuate, as between the holders of Senior Debt
and the Holders of Notes, the subordination provided in this Article Ten, and
appoints the Trustee its attorney-in-fact for such purposes, including, in the
event of any dissolution, winding-up, liquidation or reorganization of the
Company (whether in bankruptcy, insolvency, receivership, reorganization or
similar proceedings or upon an assignment for the benefit of creditors or
otherwise) tending towards liquidation of the business and assets of the
Company, and the filing of a claim for the unpaid balance of its or his Notes
and accrued interest in the form required in those proceedings.

                If the Trustee does not file a proper claim or proof of debt in
the form required in such proceeding prior to 30 days before the expiration of
the time to file such claim or claims, then the holders of the Senior Debt or
their Representative are or is hereby authorized to have the right to file and
are or is hereby authorized to file an appropriate claim for and on behalf of
the Holders of said Notes. Nothing herein contained shall be deemed to authorize
the Trustee or the holders of Senior Debt or their Representative to authorize
or consent to or accept or adopt on behalf of any Holders any plan of
reorganization, arrangement, adjustment or composition affecting the Notes or
the rights of any Holder thereof, or to authorize the Trustee or the holders of
Senior Debt or their Representative to vote in respect of the claim of any
Holder in any such proceeding.

                SECTION 10.12. This Article Ten Not To Prevent Events of
                               Default.

                The failure to make a payment on account of principal of or
interest on the Notes by reason of any provision of this Article Ten will not be
construed as preventing the occurrence of a Default or an Event of Default under
Section 6.01.

                Nothing contained in this Article Ten shall limit the right of
the Trustee or the Holders of Notes to take any action to accelerate the
maturity of the Notes pursuant to Article Six or to pursue any rights or
remedies hereunder or under 

   105
                                     -105-


applicable law, subject to the rights, if any, under this Article Ten of the
holders, from time to time, of Senior Debt.


                SECTION 10.13. Trustee's Compensation Not Prejudiced.

                Nothing in this Article Ten will apply to amounts due to the
Trustee, in its capacity as such, pursuant to other sections in this Indenture.

conflicts with another provision which is required to be included in this
Indenture by the TIA, the required provision shall control.

                    9 1/2% Senior Subordinated Note due 2008


                1. Interest. AMERICAN BUSINESS INFORMATION, INC., a Delaware
corporation (the "Company"), promises to pay interest on the principal amount of
this Note at the rate per annum shown above. Interest on the Notes will accrue
from the most recent date on which interest has been paid or, if no interest has
been paid, from June 18, 1998. The Company will pay interest semi-annually in
arrears on each Interest Payment Date, commencing December 15, 1998. Interest
will be computed on the basis of a 360-day year of twelve 30-day months.

                The Company shall pay interest on overdue principal and on
overdue installments of interest from time to time on demand at the rate borne
by the Notes and on overdue installments of interest (without regard to any
applicable grace periods) to the extent lawful.

                2. Method of Payment. The Company shall pay interest on the
Notes (except defaulted interest) to the Persons who are the registered Holders
at the close of business on the Record Date immediately preceding the Interest
Payment Date even if the Notes are canceled on registration of transfer or
registration of exchange after such Record Date. Holders must surrender Notes to
a Paying Agent to collect principal payments. The Company shall pay principal
and interest in money of the United States that at the time of payment is legal
tender for payment of public and private debts ("U.S. Legal Tender"). However,
the Company may pay principal and interest by its check payable in such U.S.
Legal Tender. The Company may deliver any such interest payment to the Paying
Agent or to a Holder at the Holder's registered address.

                3. Paying Agent and Registrar. Initially, STATE STREET BANK AND
TRUST COMPANY OF CALIFORNIA, N.A. (the "Trustee") will act as Paying Agent and
Registrar. The Company may change any Paying Agent, Registrar or co-Registrar
without notice to the Holders.

                4. Indenture. The Company issued the Notes under an Indenture,
dated as of June 18, 1998 (the "Indenture"), by and among the Company and the
Trustee. Capitalized terms herein are used as defined in this Indenture unless
otherwise defined herein. This Note is one of a duly authorized issue of Initial
Notes of the Company designated as its 9 1/2% Senior Subordinated Notes due 2008
(the "Initial Notes"). The Notes include the Initial Notes, the Private Exchange
Notes (if any) and the


                                    A.1-118
   115
Unrestricted Notes issued in exchange for the Initial Notes pursuant to the
Registration Rights Agreement. The Initial Notes and the Unrestricted Notes are
treated as a single class of securities under the Indenture. The terms of the
Notes include those stated in this Indenture and those made part of the
Indenture by reference to the Trust Indenture Act of 1939 (15 U.S. Code Sections
77aaa-77bbbb) (the "TIA"), as in effect on the date of the Indenture.
Notwithstanding anything to the contrary herein, the Notes are subject to all
such terms, and Holders of Notes are referred to the Indenture and said Act for
a statement of them. The Notes are general unsecured Obligations of the Company
limited in aggregate principal amount to $200,000,000. Each Holder, by accepting
a Note, agrees to be bound by all of the terms and provisions of the Indenture,
as the same may be amended from time to time.

                5. Subordination. The Notes are subordinated in right of
payment, in the manner and to the extent set forth in the Indenture, to the
prior payment in full in cash of all Senior Debt of the Company, whether
outstanding on the date of the Indenture or thereafter created, incurred,
assumed or guaranteed. Each Holder by its acceptance hereof agrees to be bound
by such provisions and authorizes and expressly directs the Trustee, on its
behalf, to take such action as may be necessary or appropriate to effectuate the
subordination provided for in the Indenture and appoints the Trustee its
attorney-in-fact for such purposes.

                6. Redemption Provisions. Except as provided below, the Notes
may not be redeemed prior to June 15, 2003.

        at the following redemption prices (expressed as percentages of
        principal amount), plus accrued and unpaid interest (if any) to the date
        of redemption, if redeemed during the 12-month period commencing June
        15:

                                                                 PRICE

                (b) Optional Redemption Upon Equity Offerings. Notwithstanding
        the foregoing, at any time prior to June 15, 2001, the Company may, at
        its option, redeem, in part and from time to time, with the net cash
        proceeds of one or more Equity Offerings, up to 35% of the sum of (i)
        the initial aggregate principal amount of the Notes originally issued in
        the Offering and (ii) the aggregate principal amount of any additional
        Notes issued under the Indenture after the Issue Date at a redemption
        price equal to 109.500% of the principal amount thereof plus accrued and
        unpaid interest thereon, if any, to the redemption date; provided that
        at least 65% of the sum of (i) the initial aggregate principal amount of
        the Notes issued in the Offering and (ii) the aggregate principal amount
        of any additional Notes issued under the Indenture after the Issue Date
        remains outstanding immediately after the occurrence of any such
        redemption and that any such redemption occurs within 120 days following
        the closing of any such Equity Offering.

                7. Notice of Redemption. 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 Notes to be redeemed at its registered
address. Notes in denominations larger than $1,000 may be redeemed in part. If
any Note is to be redeemed in part only, the notice of redemption that relates
to such Note shall state the portion of the principal amount thereof to be
redeemed. A new Note in a principal amount equal to the unredeemed portion
thereof will be issued in the name of the Holder thereof upon cancellation of
the original Note. On and after the Redemption Date, interest will cease to
accrue on Notes or portions thereof called for redemption as long as the Company
has deposited with the Paying Agent funds in satisfaction of the applicable
redemption price pursuant to the Indenture.

                Except as set forth in the Indenture, if monies for the
redemption of the Notes called for redemption shall have been deposited with the
Paying Agent for redemption on such Redemption Date, then, unless the Company
defaults in the payment of such Redemption Price plus accrued interest, if any,


                                    A.1-120

the Notes called for redemption will cease to bear interest from and after such
Redemption Date and the only right of the Holders of such Notes will be to
receive payment of the Redemption Price plus accrued interest, if any.

                8. Offers to Purchase. Section 4.15 of the Indenture provides
that, upon a Change of Control if the Company does not redeem the Notes, each
holder will have the right, subject to certain conditions set forth in the
Indenture, to require the Company to repurchase such holder's Notes at a price
equal to 101% of the principal amount thereof plus accrued interest to the date
of repurchase. Section 4.16 of the Indenture provides that, after certain Asset
Sales, and subject to further limitations contained therein, the Company will
make an offer to purchase certain amounts of the Notes in accordance with the
procedures set forth in the Indenture.

registered form, without coupons, in denominations of $1,000 and integral
multiples of $1,000. A Holder shall register the transfer or exchange of Notes
in accordance with the Indenture. The Registrar may require a Holder, among
other things, to furnish appropriate endorsements and transfer documents and to
pay certain transfer taxes or similar governmental charges payable in connection
therewith as permitted by the Indenture. The Registrar need not register the
transfer of or exchange of any Notes or portions thereof selected for
redemption.

                10. Persons Deemed Owners. The registered Holder of a Note shall
be treated as the owner of it for all purposes.

                11. Unclaimed Money. If money for the payment of principal or
interest remains unclaimed for two years, the Trustee and the Paying Agent will
pay the money back to the Company. After that, all liability of the Trustee and
such Paying Agent with respect to such money shall cease.

                12. Discharge Prior to Redemption or Maturity. If the Company at
any time deposits with the Trustee U.S. Legal Tender or U.S. Government
Obligations sufficient to pay the principal of, premium, if any, and interest on
the Notes to redemption or maturity and complies with the other provisions of
the Indenture relating thereto, the Company will be discharged from certain

majority in aggregate principal amount of the Notes then outstanding to direct
the Trustee in its exercise of any trust or power. The Trustee may withhold from
Holders of Notes notice of any continuing Default or Event of Default (except a
Default in payment of principal or interest) if it determines that withholding

officer, employee or incorporator, as such, of the Company shall have any
liability for any obligation of the Company under the Notes or the Indenture.

                    9 1/2% Senior Subordinated Note due 2008

                1. Interest. AMERICAN BUSINESS INFORMATION, INC., a Delaware
corporation (the "Company"), promises to pay interest on the principal amount of
this Note at the rate per annum shown above. Interest on the Notes will accrue
from the most recent date on which interest has been paid or, if no interest has
been paid, from June 18, 1998. The Company will pay interest semi-annually in
arrears on each Interest Payment Date, commencing December 15, 1998. Interest
will be computed on the basis of a 360-day year of twelve 30-day months.

                The Company shall pay interest on overdue principal and on
overdue installments of interest from time to time on demand at the rate borne
by the Notes and on overdue installments of interest (without regard to any
applicable grace periods) to the extent lawful.

                2. Method of Payment. The Company shall pay interest on the
Notes (except defaulted interest) to the Persons who are the registered Holders
at the close of business on the Record Date immediately preceding the Interest
Payment Date even if the Notes are canceled on registration of transfer or
registration of exchange after such Record Date. Holders must surrender Notes to
a Paying Agent to collect principal payments. The Company shall pay principal
and interest in money of the United States that at the time of payment is legal
tender for payment of public and private debts ("U.S. Legal Tender"). However,
the Company may pay principal and interest by its check payable in such U.S.
Legal Tender. The Company may deliver any such interest payment to the Paying
Agent or to a Holder at the Holder's registered address.

                3. Paying Agent and Registrar. Initially, STATE STREET BANK AND
TRUST COMPANY OF CALIFORNIA, N.A. (the "Trustee") will act as Paying Agent and
Registrar. The Company may change any Paying Agent, Registrar or co-Registrar
without notice to the Holders.

                4. Indenture. The Company issued the Notes under an Indenture,
dated as of June 18, 1998 (the "Indenture"), by and among the Company and the
Trustee. Capitalized terms herein are used as defined in the Indenture unless
otherwise defined herein. This Note is one of a duly authorized issue of
Unrestricted Notes of the Company designated as its 9 1/2% Senior Subordinated
Notes due 2008 (the "Unrestricted Notes"). The Notes include the Initial Notes,
the Private Exchange Notes (if any)and the Unrestricted Notes issued in exchange
for the 


                                    A.2-131
   128
Initial Notes pursuant to the Registration Rights Agreement. The Initial Notes
and the Unrestricted Notes are treated as a single class of securities under the
Indenture. The terms of the Notes include those stated in this Indenture and
those made part of the Indenture by reference to the Trust Indenture Act of 1939
(15 U.S. Code Sections 77aaa-77bbbb) (the "TIA"), as in effect on the date of
the Indenture. Notwithstanding anything to the contrary herein, the Notes are
subject to all such terms, and Holders of Notes are referred to the Indenture
and said Act for a statement of them. The Notes are general unsecured
Obligations of the Company limited in aggregate principal amount to
$200,000,000. Each Holder, by accepting a Note, agrees to be bound by all of the
terms and provisions of the Indenture, as the same may be amended from time to
time.

                5. Subordination. The Notes are subordinated in right of
payment, in the manner and to the extent set forth in the Indenture, to the
prior payment in full in cash of all Senior Debt of the Company, whether
outstanding on the date of the Indenture or thereafter created, incurred,
assumed or guaranteed. Each Holder by its acceptance hereof agrees to be bound
by such provisions and authorizes and expressly directs the Trustee, on its
behalf, to take such action as may be necessary or appropriate to effectuate the
subordination provided for in the Indenture and appoints the Trustee its
attorney-in-fact for such purposes.

                6. Redemption Provisions. Except as provided below, the Notes
may not be redeemed prior to June 15, 2003.

                (a) Optional Redemption. On or after such date, the Notes may be
redeemed at the option of the Company, at any time as a whole, or from time to
time in part, on not less than 30 nor more than 60 days' notice, at the
following redemption prices (expressed as percentages of principal amount), plus

                (b) Optional Redemption Upon Equity Offerings. Notwithstanding
the foregoing, at any time prior to June 15, 2001, the Company may, at its
option, redeem, in part and from time to time, with the net cash proceeds of one

aggregate principal amount of any additional Notes issued under the Indenture

amount thereof plus accrued and unpaid interest thereon, if any, to the
redemption date; provided that at least 65% of the sum of (i) the initial
aggregate principal amount of the Notes issued in the Offering and (ii) the
aggregate principal amount of any additional Notes issued under the Indenture
after the Issue Date remains outstanding immediately after the occurrence of any
such redemption and that any such redemption occurs within 120 days following

any Note is to be redeemed in part only, the notice of redemption that relates
to such Note shall state the portion of the principal amount thereof to be
redeemed. A new Note in a principal amount equal to the unredeemed portion
thereof will be issued in the name of the Holder thereof upon cancellation of
the original Note. On and after the Redemption Date, interest will cease to
accrue on Notes or portions thereof called for redemption as long as the Company
has deposited with the paying agent funds in satisfaction of the applicable
redemption price pursuant to the Indenture.

                Except as set forth in the Indenture, if monies for the
redemption of the Notes called for redemption shall have been deposited with the
Paying Agent for redemption on such Redemption Date, then, unless the Company
defaults in the payment of such Redemption Price plus accrued interest, if any,
the Notes called for redemption will cease to bear interest from and after such

Redemption Price plus accrued interest, if any.

                8. Offers to Purchase. Section 4.15 of the Indenture provides
that, upon a Change of Control if the Company does not redeem the Notes, each
holder will have the right, subject to certain conditions set forth in the
Indenture, to require the Company to repurchase such holder's Notes at a price
equal to 101% of the principal amount thereof plus accrued interest to the date
of repurchase. Section 4.16 of the Indenture provides that, after certain Asset
Sales, and subject to further limitations contained therein, the Company will
make an offer to purchase certain amounts of the Notes in accordance with the
procedures set forth in the Indenture.

therewith as permitted by the Indenture. The Registrar need not register the
transfer of or exchange of any Notes or portions thereof selected for
redemption.

                10. Persons Deemed Owners. The registered Holder of a Note shall
be treated as the owner of it for all purposes.

                11. Unclaimed Money. If money for the payment of principal or
interest remains unclaimed for two years, the Trustee and the Paying Agent will
pay the money back to the Company. After that, all liability of the Trustee and
such Paying Agent with respect to such money shall cease.

                12. Discharge Prior to Redemption or Maturity. If the Company at
any time deposits with the Trustee U.S. Legal Tender or U.S. Government
Obligations sufficient to pay the principal of, premium, if any, and interest on
the Notes to redemption or maturity and complies with the other provisions of
the Indenture relating thereto, the Company will be discharged from certain
provisions of the Indenture and the Notes (including certain covenants, but
excluding its obligation to pay the principal of and interest on the Notes).

                13. Amendment; Supplement; Waiver. Subject to certain
exceptions, the Indenture or the Notes may be amended or supplemented with the
written consent of the Holders of at least a majority in aggregate principal
amount of the Notes then outstanding, and any existing Default or Event of
Default or noncompliance with any provision may be waived with the written
consent of the Holders of a majority in aggregate 


                                    A.2-134
   131

any Holder, the parties thereto may amend or supplement the Indenture or the
Notes to, among other things, cure any ambiguity, defect or inconsistency,
provide for uncertificated Notes in addition to or in place of certificated
Notes, or comply with Article Five of the Indenture or make any other change
that does not adversely affect in any material respect the rights of any Holder
of a Note.

                14. Restrictive Covenants. The Indenture imposes certain
limitations on the ability of the Company and its Restricted Subsidiaries to,
among other things, incur additional Indebtedness or Liens, make payments in
respect of its Capital Stock or certain Indebtedness, enter into transactions
with Affiliates, create dividend or other payment restrictions affecting
Subsidiaries, incur additional senior subordinated Indebtedness, merge or
consolidate with any other Person, sell, assign, transfer, lease, convey or
otherwise dispose of all or substantially all of its assets or adopt a plan of
liquidation and sell Capital Stock of a Restricted Subsidiary. Such limitations
are subject to a number of important qualifications and exceptions. The Company
must annually report to the Trustee on compliance with such limitations.

                15. Successors. When a successor assumes, in accordance with the
Indenture, all the Obligations of its predecessor under the Notes and the
Indenture, the predecessor will be released from those Obligations.

                16. Defaults and Remedies. If an Event of Default occurs and is
continuing, the Trustee or the Holders of at least 25% in aggregate principal
amount of Notes then outstanding may declare all the Notes to be due and payable
in the manner, at the time and with the effect provided in the Indenture.
Holders of Notes may not enforce the Indenture or the Notes except as provided
in the Indenture. The Trustee is not obligated to enforce the Indenture or the
Notes unless it has received indemnity reasonably satisfactory to it. The
Indenture permits, subject to certain limitations therein provided, Holders of a
majority in aggregate principal amount of the Notes then outstanding to direct
the Trustee in its exercise of any trust or power. The Trustee may withhold from
Holders of Notes notice of any continuing Default or Event of Default (except a
Default in payment of principal or interest) if it determines that withholding
notice is in their interest.

                17. Trustee Dealings with Company. The Trustee under the
Indenture, in its individual or any other capacity, may become the owner or
pledgee of Notes and may otherwise deal with the Company, its Subsidiaries or
their respective 



                                    A.2-135
   132
Affiliates as if it were not the Trustee.

                18. No Recourse Against Others. No stockholder, director,
officer, employee or incorporator, as such, of the Company shall have any
liability for any obligation of the Company under the Notes or the Indenture.
Each Holder of a Note by accepting a Note waives and releases all such
liability. The waiver and release are part of the consideration for the issuance
of the Notes.

                19. Authentication. This Note shall not be valid until the
Trustee or Authenticating Agent manually signs the certificate of authentication
on this Note.

                20. Governing Law. The laws of the State of New York shall
govern this Note and the Indenture, without regard to principles of conflict of
laws.

                21. Abbreviations and Defined Terms. Customary abbreviations may
be used in the name of a Holder of a Note or an assignee, such as: TEN COM (=

                22. CUSIP Numbers. Pursuant to a recommendation promulgated by
the Committee on Uniform Security Identification Procedures, the Company has
caused CUSIP numbers to be printed on the Notes as a convenience to the Holders

                       (the "Company")
                       9 1/2% Senior Subordinated
                       Notes due 2008 (the "Notes")

Ladies and Gentlemen:

                In connection with our proposed purchase of $_______ aggregate
principal amount of the Notes, we confirm that:

                1. We have received a copy of the Offering Memorandum (the
"Offering Memorandum"), dated [   ], 1998, relating to the Notes and such other
information as we deem necessary in order to make our investment decision. We
acknowledge that we have read and agreed to the matters stated on pages
(i)-(iii) of the Offering Memorandum and in the section entitled "Transfer
Restrictions" of the Offering Memorandum, including the restrictions on
duplication and circulation of the Offering Memorandum.

                2. We understand that any subsequent transfer of the Notes is
subject to certain restrictions and conditions set forth in the Indenture dated
as of [   ], 1998 relating to the Notes (the "Indenture") and the undersigned
agrees to be bound by, and not to resell, pledge or otherwise transfer the Notes
except in compliance with, such restrictions and conditions and the Securities
Act of 1933, as amended (the "Securities Act").

                3. We understand that the offer and sale of the Notes have not
been registered under the Securities Act, and that the Notes may not be offered
or sold within the United States or to, or for the account or benefit of,
Persons 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 


                                      C-140
   137
hereinafter stated, that if we should sell or otherwise transfer any Notes we
will do so only (i) to the Company or any subsidiary thereof, (ii) in accordance
with Rule 144A under the Securities Act to a "qualified institutional buyer" (as
defined in Rule 144A under the Securities Act), (iii) 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 a signed letter
containing certain representations and agreements relating to the restrictions
on transfer of the Notes, substantially in the form of this letter, (iv)
pursuant to the exemption from registration provided by Rule 144 under the
Securities Act (if available), or (v) pursuant to an effective registration
statement under the Securities Act, and we further agree to provide to any
person purchasing any of the Notes from us a notice advising such purchaser that
resales of the Notes are restricted as stated herein.

                4. We are not acquiring the Notes for or on behalf of, and will
not transfer the Notes to, any pension or welfare plan (as defined in Section 3
of the Employee Retirement Income Security Act of 1974), except as permitted in
the section entitled "Transfer Restrictions" of the Offering Memorandum.

                5. We understand that, on any proposed resale of any Notes, we
will be required to furnish to you and the Company such certification, legal
opinions and other information as you and the Company may reasonably require to
confirm that the proposed sale complies with the foregoing restrictions. We
further understand that the Notes purchased by us will bear a legend to the
foregoing effect.

                6. 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 their investment, as the case may be.


                                      C-141
   138
                7. We are acquiring the Notes 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.

                You, the Company and the Initial Purchasers (as defined in the
Offering Memorandum) 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.

                                       Very truly yours,


                                       [Name of Transferee]
