at the time a Note is authenticated, the Note shall nevertheless be valid.

          A Note shall not be valid until authenticated by the manual signature
of the Trustee.  The signature shall be conclusive evidence that the Note has

Holders or the Trustee all money held by the Paying Agent for the payment of
principal, premium or Liquidated Damages, if any, or interest on the Notes, and
will notify the Trustee of any default by the Issuers in making any such
payment.  While any such default continues, the Trustee may require a Paying
Agent to pay all money held by it to the Trustee.  The Issuers at any time may
require a Paying Agent to pay all money held by it to the Trustee.  Upon payment
over to the Trustee, the Paying Agent (if other than the Issuers or a Subsidiary
of either Issuer) shall have no further liability for the money.  If the Issuers
or a Subsidiary of either Issuer acts as Paying Agent, it shall segregate and
hold in a separate trust fund for the benefit of the Holders all money held by
it as Paying Agent.  Upon any bankruptcy or reorganization proceedings relating
to the Issuers, the Trustee shall serve as Paying Agent for the Notes.

          (ii)   Global Note Legend. Each Global Note shall bear a legend in
     substantially the following form:

                                     -44-

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

          (i)    General Provisions Relating to Transfers and Exchanges.

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

            (ii)   No service charge shall be made to a holder of a beneficial
     interest in a Global Note or to a Holder of a Definitive Note for any
     registration of transfer or exchange, but the Issuers may require payment
     of a sum sufficient to cover any transfer tax or similar governmental
     charge payable in connection therewith (other than any such transfer taxes
     or similar governmental charge payable upon exchange or transfer pursuant
     to Sections 2.10, 3.06, 3.09, 4.10, 4.15 and 9.05 hereof).

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

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

            (v)    The Issuers shall not be required (A) to issue, to register
     the transfer of or to exchange any Notes during a period beginning at the
     opening of business 15 days before the day of any selection of Notes for
     redemption under Section 3.02

 
                                     -45-

     hereof and ending at the close of business on the day of selection, (B) to
     register the transfer of or to exchange any Note so selected for redemption
     in whole or in part, except the unredeemed portion of any Note being
     redeemed in part or (c) to register the transfer of or to exchange a Note
     between a record date and the next succeeding Interest Payment Date.

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

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

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

          SECTION 2.07.  Replacement Notes.
                         ----------------- 

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

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

          SECTION 2.08.  Outstanding Notes.
                         ----------------- 

          The Notes outstanding at any time are all the Notes authenticated by
the Trustee except for those canceled by it, those delivered to it for
cancellation, those reductions in the interest in a Global Note effected by the
Trustee in accordance with the provisions hereof, and those described in this
Section as not outstanding.  Except as set forth in

 
                                     -46-

Section 2.09 hereof, a Note does not cease to be outstanding because the Issuers
or an Affiliate of the Issuers holds the Note; however, Notes held by the
Issuers or a Subsidiary of the Issuers shall not be deemed to be outstanding for
purposes of Section 3.07(b) hereof.

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

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

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

          SECTION 2.09.  Treasury Notes.
                         -------------- 

          In determining whether the Holders of the required principal amount of
Notes have concurred in any direction, waiver or consent, Notes owned by the
Issuers, or by any Person directly or indirectly controlling or controlled by or
under direct or indirect common control with the Issuers, shall be considered as
though not outstanding, except that for the purposes of determining whether the
Trustee shall be protected in relying on any such direction, waiver or consent,
only Notes that the Trustee actually knows are so owned shall be so disregarded.

          SECTION 2.10.  Temporary Notes.
                         --------------- 

          Until certificates representing Notes are ready for delivery, the
Issuers may prepare and the Trustee, upon receipt of an Authentication Order,
shall authenticate temporary Notes.  Temporary Notes shall be substantially in
the form of certificated Notes but may have variations that the Issuers consider
appropriate for temporary Notes and as shall be reasonably acceptable to the
Trustee.  Without unreasonable delay, the Issuers shall prepare and the Trustee
shall authenticate definitive Notes in exchange for temporary Notes.

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

          SECTION 2.11.  Cancellation.
                         ------------ 

          The Issuers at any time may deliver Notes to the Trustee for
cancellation.  The Registrar and Paying Agent shall forward to the Trustee any
Notes surrendered to them 

 
                                     -47-

for registration of transfer, exchange or payment. The Trustee and no one else
shall cancel all Notes surrendered for registration of transfer, exchange,
payment, replacement or cancellation and shall destroy canceled Notes (subject
to the record retention requirement of the Exchange Act). Certification of the
destruction of all canceled Notes shall be delivered to the Issuers. The Issuers
may not issue new Notes to replace Notes that they have paid or that have been
delivered to the Trustee for cancellation.

          SECTION 2.12.  Defaulted Interest.
                         ------------------ 

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

                                 ARTICLE THREE

                           REDEMPTION AND PREPAYMENT

          SECTION 3.01.  Notices to Trustee.
                         ------------------ 

          If the Issuers elect to redeem Notes pursuant to the optional
redemption provisions of Section 3.07 hereof, they each shall furnish to the
Trustee, at least 35 days but not more than 60 days before a redemption date, an
Officers' Certificate setting forth (i) the clause of this Indenture pursuant to
which the redemption shall occur, (ii) the redemption date, (iii) the principal
amount of Notes to be redeemed and (iv) the redemption price.

          SECTION 3.02.  Selection of Notes to Be Redeemed.
                         --------------------------------- 

          If less than all of the Notes are to be redeemed or purchased in an
offer to purchase at any time, the Trustee shall select the Notes to be redeemed
or purchased among the Holders of the Notes in compliance with the requirements
of the principal national securities exchange, if any, on which the Notes are
listed or, if the Notes are not so listed, on a 

 
                                     -48-

pro rata basis, by lot or in accordance with any other method the Trustee
considers fair and appropriate. In the event of partial redemption by lot, the
particular Notes to be redeemed shall be selected, unless otherwise provided
herein, not less than 30 nor more than 60 days prior to the redemption date by
the Trustee from the outstanding Notes not previously called for redemption.

          The Trustee shall promptly notify the Issuers 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 and portions of
Notes selected shall be in amounts of $1,000 or whole multiples of $1,000 except
that if all of the Notes of a Holder are to be redeemed, the entire outstanding
amount of Notes held by such Holder, even if not a multiple of $1,000, shall be
redeemed.  Except as provided in the preceding sentence, 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.
                         -------------------- 

          Subject to the provisions of Section 3.09 hereof, at least 30 days but
not more than 60 days before a redemption date, the Issuers shall mail or cause
to be mailed, by first class mail, a notice of redemption to each Holder whose
Notes are to be redeemed at its registered address.

          The notice shall identify the Notes to be redeemed and shall state:

          (a)  the redemption date;

          (b)  the redemption price;

          (c)  if any Note is being redeemed in part, the portion of the
     principal amount of such Note to be redeemed and that, after the redemption
     date upon surrender of such Note, a new Note or Notes in principal amount
     equal to the unredeemed portion shall be issued upon cancellation of the
     original Note;

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

          (e)  that Notes called for redemption must be surrendered to the
     Paying Agent to collect the redemption price;

          (f)  that, unless the Issuers default in making such redemption
     payment, interest on Notes called for redemption ceases to accrue on and
     after the redemption date;

 
                                     -49-

          (g)  the paragraph of the Notes and/or Section of this Indenture
     pursuant to which the Notes called for redemption are being redeemed; and

          (h)  that no representation is made as to the correctness or accuracy
     of the CUSIP number, if any, listed in such notice or printed on the Notes.

          At the Issuers' request, the Trustee shall give the notice of
redemption in the Issuers' names and at the Issuers' expense; provided, however,
that each of the Issuers shall have delivered to the Trustee, at least 45 days
prior to the redemption date, an Officers' Certificate requesting that the
Trustee give such notice and setting forth the information to be stated in such
notice as provided in the preceding paragraph.

          SECTION 3.04.  Effect of Notice of Redemption.
                         ------------------------------ 

          Once notice of redemption is mailed in accordance with Section 3.03
hereof, Notes called for redemption become irrevocably due and payable on the
redemption date at the redemption price.  A notice of redemption may not be
conditional.

          SECTION 3.05.  Deposit of Redemption Price.
                         --------------------------- 

          One Business Day prior to the redemption date, the Issuers shall
deposit with the Trustee or with the Paying Agent money sufficient to pay the
redemption price of and accrued interest on all Notes to be redeemed on that
date.  The Trustee or the Paying Agent shall promptly return to the Issuers any
money deposited with the Trustee or the Paying Agent by the Issuers in excess of
the amounts necessary to pay the redemption price of, and accrued interest on,
all Notes to be redeemed.

          If the Issuers comply with the provisions of the preceding paragraph,
on and after the redemption date, interest shall cease to accrue on the Notes or
the portions of Notes called for redemption.  If a Note is redeemed on or after
an interest record date but on or prior to the related interest payment date,
then any accrued and unpaid interest shall be paid to the Person in whose name
such Note was registered at the close of business on such record date.  If any
Note called for redemption shall not be so paid upon surrender for redemption
because of the failure of the Issuers to comply with the preceding paragraph,
interest shall be paid on the unpaid principal, from the redemption date until
such principal is paid, and to the extent lawful on any interest not paid on
such unpaid principal, in each case at the rate provided in the Notes and in
Section 4.01 hereof.

          SECTION 3.06.  Notes Redeemed in Part.
                         ---------------------- 

          Upon surrender of a Note that is redeemed in part, the Issuers shall
issue and, upon the Issuers' written request, the Trustee shall authenticate for
the Holder at the 

 
                                     -50-

expense of the Issuers a new Note equal in principal amount to the unredeemed
portion of the Note surrendered.

          SECTION 3.07.  Optional Redemption.
                         ------------------- 

          (a) The Notes will be subject to redemption at any time at the option
of the Company, in whole or in part, upon not less than 30 nor more than 60
days' notice, at the redemption prices (expressed as percentages of principal
amount) set forth below plus accrued and unpaid interest and Liquidated Damages
thereon to the applicable redemption date if redeemed during the twelve-month
period beginning on each December 15 of the years indicated below:

 
 
          YEAR                          PERCENTAGE
          ----                          ----------
                                      
          2002.......................   105.250%
          2003.......................   103.500%
          2004 and thereafter........   101.750%
 

          In addition, prior to December 15, 2002, the Notes will be redeemable
at a price equal to 100% of the principal amount thereof plus an applicable Make
Whole Premium, plus, to the extent not included in the Make Whole Premium,
accrued and unpaid interest and Liquidated Damages, if any, to the date of
redemption.

          For purposes of the foregoing, the "Make Whole Premium" means, with
respect to a Note, an amount equal to the greater of (A) the redemption price of
such Note on December 15, 2002 and (B) the excess of, if any, (1) the present
value of the remaining interest, premium, if any, and principal payments due on
such Note as if such Note were redeemed on December 15, 2002, computed using a
discount rate equal to the Treasury Rate plus 50 basis points, over (2) the
outstanding principal amount of such Note.

          "Treasury Rate" means the yield to maturity at the time of computation
of United States Treasury securities with a constant maturity (as compiled by,
and published in, the most recent Federal Reserve Statistical Release H.15 (519)
which has become publicly available at least two business days prior to the date
fixed for redemption of the Notes (or, if such Statistical Release is no longer
published, any publicly available source of similar market data)) most nearly
equal to the then remaining Weighted Average Life to Maturity of the Notes;
provided, however, that if the Weighted Average Life to Maturity of the Notes is
not equal to the constant maturity of a United States Treasury security for
which a weekly average yield is given, the Treasury Rate shall be obtained by
linear interpolation (calculated to the nearest one-twelfth of a year) from the
weekly average yields of United States Treasury securities for which such yields
are given, except that if the Weighted Average Life to Maturity of the Notes is
less than one year, the weekly average 

 
                                      51-

yield on actually traded United States Treasury securities adjusted to a
constant maturity of one year shall be used.

          (b)  Notwithstanding the foregoing, at any time on or before December
15, 2000, the Company may on any one or more occasions redeem up to 35% of the
aggregate principal amount of Notes ever issued under this Indenture at a
redemption price equal to the principal amount thereof plus a premium equal to
110 1/2% of the principal amount thereof, plus accrued and unpaid interest and
Liquidated Damages thereon, if any, to the redemption date, with the net cash
proceeds of an initial public offering of common stock of the Company or
Holdings (to the extent that the net proceeds therefrom are contributed to the
Company as common equity capital); provided that at least 65% of the aggregate
principal amount of Notes issued on the date of this Indenture remains
outstanding immediately after the occurrence of such redemption (excluding Notes
held by Holdings or the Company and their Subsidiaries) and provided, further,
that such redemption shall occur within 45 days of the date of the closing of
such initial public offering.

          (c) Any redemption pursuant to this Section 3.07 shall be made
pursuant to the provisions of Section 3.01 through 3.06 hereof.

          SECTION 3.08.  Mandatory Redemption.
                         -------------------- 

          The Issuers shall not be required to make mandatory redemption
payments with respect to the Notes.

          SECTION 3.09.  Offer to Purchase by Application of Excess Proceeds.
                         ---------------------------------------------------

          In the event that, pursuant to Section 4.10 hereof, the Issuers shall
be required to commence an offer to all Holders to purchase Notes (an "Asset
Sale Offer"), they shall follow the procedures specified below.

          The Asset Sale Offer shall remain open for a period of 20 Business
Days following its commencement and no longer, except to the extent that a
longer period is required by applicable law (the "Offer Period").  No later than
five Business Days after the termination of the Offer Period (the "Purchase
Date"), the Issuers shall purchase the principal amount of Notes required to be
purchased pursuant to Section 4.10 hereof (the "Offer Amount") or, if less than
the Offer Amount has been tendered, all Notes tendered in response to the Asset
Sale Offer.  Payment for any Notes so purchased shall be made in the same manner
as interest payments are made.

 
                                     -52-

          If the Purchase Date is on or after an interest record date and on or
before the related interest payment date, any accrued and unpaid interest shall
be paid to the Person in whose name a Note is registered at the close of
business on such record date, and no additional interest shall be payable to
Holders who tender Notes pursuant to the Asset Sale Offer.

          Upon the commencement of an Asset Sale Offer, the Issuers shall send,
by first class mail, a notice to the Trustee and each of the Holders.  The
notice shall contain all instructions and materials necessary to enable such
Holders to tender Notes pursuant to the Asset Sale Offer.  The Asset Sale Offer
shall be made to all Holders.  The notice, which shall govern the terms of the
Asset Sale Offer, shall state:

          (a) that the Asset Sale Offer is being made pursuant to this Section
     3.09 and Section 4.10 hereof and the length of time the Asset Sale Offer
     shall remain open;

          (b) the Offer Amount, the purchase price and the Purchase Date;

          (c) that any Note not tendered or accepted for payment shall continue
     to accrue interest;

          (d) that, unless the Issuers default in making such payment, any Note
     accepted for payment pursuant to the Asset Sale Offer shall cease to accrue
     interest after the Purchase Date;

          (e) that Holders electing to have a Note purchased pursuant to an
     Asset Sale Offer may only elect to have all of such Note purchased and may
     not elect to have only a portion of such Note purchased;

          (f) that Holders electing to have a Note purchased pursuant to any
     Asset Sale Offer shall be required to surrender the Note, with the form
     entitled "Option of Holder to Elect Purchase" on the reverse of the Note
     completed, or transfer by book-entry transfer, to the Issuers, a
     depositary, if appointed by the Issuers, or a Paying Agent at the address
     specified in the notice at least three days before the Purchase Date;

          (g) that Holders shall be entitled to withdraw their election if the
     Issuers, the depositary or the Paying Agent, as the case may be, receives,
     not later than the expiration of the Offer Period, a telegram, telex,
     facsimile transmission or letter setting forth the name of the Holder, the
     principal amount of the Note the Holder 

 
                                     -53-

     delivered for purchase and a statement that such Holder is withdrawing his
     election to have such Note purchased;

          (h) that, if the aggregate principal amount of Notes surrendered by
     Holders exceeds the Offer Amount, the Issuers shall select the Notes to be
     purchased on a pro rata basis (with such adjustments as may be deemed
     appropriate by the Issuers so that only Notes in denominations of $1,000,
     or integral multiples thereof, shall be purchased); and

          (i) that Holders whose Notes were purchased only in part shall be
     issued new Notes equal in principal amount to the unpurchased portion of
     the Notes surrendered (or transferred by book-entry transfer).

          On or before the Purchase Date, the Issuers shall, to the extent
lawful, accept for payment, on a pro rata basis to the extent necessary, the
Offer Amount of Notes or portions thereof tendered pursuant to the Asset Sale
Offer, or if less than the Offer Amount has been tendered, all Notes tendered,
and each shall deliver to the Trustee an Officers' Certificate stating that such
Notes or portions thereof were accepted for payment by the Issuers in accordance
with the terms of this Section 3.09.  The Issuers, the Depositary or the Paying
Agent, as the case may be, shall promptly (but in any case not later than five
days after the Purchase Date) mail or deliver to each tendering Holder an amount
equal to the purchase price of the Notes tendered by such Holder and accepted by
the Issuers for purchase, and the Issuers shall promptly issue a new Note, and
the Trustee, upon written request from the Issuers shall authenticate and mail
or deliver such new Note to such Holder, in a principal amount equal to any
unpurchased portion of the Note surrendered.  Any Note not so accepted shall be
promptly mailed or delivered by the Issuers to the Holder thereof.  The Issuers
shall publicly announce the results of the Asset Sale Offer on the Purchase
Date.

          Other than as specifically provided in this Section 3.09, any purchase

          The Issuers shall pay or cause to be paid the principal of, premium,
if any, and interest on the Notes on the dates and in the manner provided in the
Notes.  Principal, premium, if any, and interest shall be considered paid on the
date due if the Paying Agent, if other than the Issuers or a Subsidiary thereof,
holds as of 10:00 a.m. Eastern Time on the due date money deposited by the
Issuers in immediately available funds and designated for and sufficient to pay
all principal, premium, if any, and interest then due.  The Issuers shall pay
all Liquidated Damages, if any, in the same manner on the dates and in the
amounts set forth in the Registration Rights Agreement.

          The Issuers shall pay interest (including post-petition interest in
any proceeding under any Bankruptcy Law) on overdue principal at the rate equal
to 1% per annum in excess of the then applicable interest rate on the Notes to
the extent lawful; they shall pay interest (including post-petition interest in
any proceeding under any Bankruptcy Law) on overdue installments of interest and
Liquidated Damages (without regard to any applicable grace period) at the same
rate to the extent lawful.

          SECTION 4.02. Maintenance of Office or Agency.
                        ------------------------------- 

          Each Issuer shall maintain in the Borough of Manhattan, the City of
New York, an office or agency (which may be an office of the Trustee or an
affiliate of the Trustee, Registrar or co-registrar) where Notes may be
surrendered for registration of transfer or for exchange and where notices and
demands to or upon the Issuers in respect of the Notes and this Indenture may be
served.  The Issuers shall give prompt written notice to the Trustee of the
location, and any change in the location, of such office or agency.  If at any
time the Issuers shall fail to maintain any such required office or agency or
shall fail to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the Corporate Trust
Office of the Trustee.

          The Issuers may also from time to time designate one or more other
offices or agencies where the Notes may be presented or surrendered for any or
all such purposes and may from time to time rescind such designations; provided,
however, that no such designation or rescission shall in any manner relieve the
Issuers of their obligation to maintain an office or agency in the Borough of
Manhattan, the City of New York for such purposes.

 
                                     -55-

The Issuers shall give prompt written notice to the Trustee of any such
designation or rescission and of any change in the location of any such other
office or agency.

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

          SECTION 4.03. Reports.

Commission on Forms 10-Q and 10-K if the Company were required to file such
Forms, including a ''Management's Discussion and Analysis of Financial Condition

of operations of the Company and its consolidated Subsidiaries (showing in
reasonable detail, either on the face of the financial statements or in the
footnotes thereto and in Management's Discussion and Analysis of Financial
Condition and Results of Operations, the financial condition and results of
operations of the Company and its Restricted Subsidiaries separate from the
financial condition and results of operations of the Unrestricted Subsidiaries
of the Company) and, with respect to the annual information only, a report
thereon by the Company's certified independent accountants and (ii) all current
reports that would be required to be filed with the Commission on Form 8-K if
the Company were required to file such reports, in each case within the time
periods specified in the Commission's rules and regulations. In addition,
whether or not required by the rules and regulations of the Commission, the
Company shall file a copy of all such information and reports with the
Commission for public availability within the time periods specified in the
Commission's rules and regulations (unless the Commission will not accept such a
filing) and make such information available to securities analysts and
prospective investors upon request.  The Issuers shall at all times comply with
TIA (S) 314(a).

that, for so long as any Notes remain outstanding, they shall furnish to the
Holders and to securities analysts and prospective investors, upon their
request, the information required to be delivered pursuant to Rule 144A(d)(4)
under the Securities Act.

          SECTION 4.04. Compliance Certificate.
                        ---------------------- 

          (a) Each of the Issuers and each Guarantor (to the extent that such
Guarantor is so required under the TIA) shall deliver to the Trustee, within 90
days after the end of each fiscal year, an Officers' Certificate stating that a
review of the activities of the Issuers and their Subsidiaries during the
preceding fiscal year has been made under the supervi-

 
                                     -56-

sion of the signing Officers with a view to determining whether the Issuers have
kept, observed, performed and fulfilled their obligations under this Indenture,
and further stating, as to each such Officer signing such certificate, that to
the best of his or her knowledge the Issuers have kept, observed, performed and
fulfilled each and every covenant contained in this Indenture and are not in
default in the performance or observance of any of the terms, provisions and
conditions of this Indenture (or, if a Default or Event of Default shall have
occurred, describing all such Defaults or Events of Default of which he or she
may have knowledge and what action the Issuers are taking or propose to take
with respect thereto) and that to the best of his or her knowledge no event has
occurred and remains in existence by reason of which payments on account of the
principal of or interest, if any, on the Notes is prohibited or if such event
has occurred, a description of the event and what action the Issuers are taking
or propose to take with respect thereto.

          (b) So long as not contrary to the then current recommendations of the
American Institute of Certified Public Accountants, the year-end financial
statements delivered pursuant to Section 4.03(a) above shall be accompanied by a
written statement of the Issuers' independent public accountants (who shall be a
firm of established national reputation) that in making the examination
necessary for certification of such financial statements, nothing has come to
their attention that would lead them to believe that the Issuers have violated
any provisions of Article 4 or Article 5 hereof 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) Each of the Issuers shall, so long as any of the Notes are
outstanding, deliver to the Trustee, forthwith (and in no event more than five
Business Days after) upon any Officer becoming aware of any Default or Event of
Default, an Officers' Certificate specifying such Default or Event of Default
and what action the Issuers are taking or propose to take with respect thereto.

          SECTION 4.05. Taxes.
                        ----- 

          The Issuers shall pay, and shall cause each of their Subsidiaries to
pay, prior to delinquency, all material taxes, assessments, and governmental
levies except such as are contested in good faith and by appropriate proceedings
or where the failure to effect such payment is not adverse in any material
respect to the Holders of the Notes.

          SECTION 4.06. Stay, Extension and Usury Laws.
                        ------------------------------ 

          The Issuers and each of the Guarantors covenant (to the extent that
they may lawfully do so) that they shall not at any time insist upon, plead, or
in any manner whatso-

 
                                     -57-

ever claim or take the benefit or advantage of, any stay, extension or usury law
wherever enacted, now or at any time hereafter in force, that may affect the
covenants or the performance of this Indenture; and the Issuers and each of the
Guarantors (to the extent that they may lawfully do so) hereby expressly waive
all benefit or advantage of any such law, and covenants that they shall not, by
resort to any such law, 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 has been enacted.

          SECTION 4.07. Restricted Payments.
                        ------------------- 

          The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly make any Restricted Payment of the types
described in clauses (i) and (ii) of the definition of Restricted Payments prior
to the first anniversary of the date of this Indenture.  The Company shall not
at any time thereafter, and shall not permit any of its Restricted Subsidiaries
to, directly or indirectly: (i) declare or pay any dividend or make any other
payment or distribution on account of the Company's or any of its Restricted
Subsidiaries' Equity Interests (including, without limitation, any payment in
connection with any merger or consolidation involving the Company or any of its
Restricted Subsidiaries) or to the direct or indirect holders of the Company's
or any of its Restricted Subsidiaries' Equity Interests in their capacity as
such (other than dividends or distributions payable in Equity Interests (other
than Disqualified Stock) of the Company); (ii) purchase, redeem or otherwise
acquire or retire for value (including, without limitation, in connection with
any merger or consolidation involving the Company) any Equity Interests of the
Company or any direct or indirect parent of the Company; (iii) make any payment
on or with respect to, or purchase, redeem, defease or otherwise acquire or
retire for value any Indebtedness that is subordinated to the Notes or any
Subsidiary Guarantee, except a payment of interest or principal at Stated
Maturity; or (iv) make any Restricted Investment (all such payments and other
actions set forth in clauses (i) through (iv) above being collectively referred
to as ''Restricted Payments''), unless, at the time of and after giving effect
to such Restricted Payment:

          (a) no Default or Event of Default shall have occurred and be
     continuing or would occur as a consequence thereof; and

          (b) the Company would, at the time of such Restricted Payment and
     after giving pro forma effect thereto as if such Restricted Payment had
     been made at the beginning of the applicable four-quarter period, have been
     permitted to incur at least $1.00 of additional Indebtedness pursuant to
     the Fixed Charge Coverage Ratio test set forth in the first paragraph of
     Section 4.09; and

 
                                     -58-

          (c) such Restricted Payment, together with the aggregate amount of all
     other Restricted Payments made by the Company and its Subsidiaries after
     the date of this Indenture (excluding Restricted Payments permitted by
     clauses (ii), (iii), (iv), (v), (vii), (viii) and (ix) of the next
     succeeding paragraph), is less than the sum, without duplication, of (i)
     50% of the Consolidated Net Income of the Company for the period (taken as
     one accounting period) from the date of the closing of the issuance of the
     Notes to the end of the Company's most recently ended fiscal quarter for
     which internal financial statements are available at the time of such
     Restricted Payment (or, if such Consolidated Net Income for such period is
     a deficit, less 100% of such deficit), plus (ii) 100% of the aggregate net
     cash proceeds received by the Company since the date of the closing of the
     issuance of the Notes as a contribution to its common equity capital or
     from the issue or sale of Equity Interests of the Company (other than
     Disqualified Stock) or from the issue or sale of Disqualified Stock or debt
     securities of the Company that have been converted into such Equity
     Interests (other than Equity Interests (or Disqualified Stock or
     convertible debt securities) sold to a Subsidiary of the Company), plus
     (iii) to the extent that any Restricted Investment that reduced the amount
     available for Restricted Payments under this clause (c) is sold for cash or
     otherwise liquidated or repaid for cash or any dividend or payment is
     received by the Company or a Restricted Subsidiary after the date of the
     closing of the Acquisitions in respect of such Investment, 100% of the
     amount of Net Proceeds or dividends or payments (including the fair market
     value of property) received in connection therewith, up to the amount of
     the Restricted Investment that reduced this clause (c), and thereafter 50%
     of the amount of Net Proceeds or dividends or payments (including the fair
     market value of property) received in connection therewith (except that the
     amount of dividends or payments received in respect of payments of
     Obligations in respect of such Investments, such as taxes, shall not
     increase the amounts under this clause (c)), plus (iv) to the extent that
     any Unrestricted Subsidiary of the Company is redesignated as a Restricted
     Subsidiary after the date of this Indenture, 100% of the fair market value
     of the Company's Investment in such Subsidiary as of the date of such
     redesignation up to the amount of the Restricted Investments made in such
     Subsidiary that reduced this clause (c) and 50% of the excess of the fair
     market value of the Company's Investment in such Subsidiary as of the date
     of such redesignation over (1) the amount of the Restricted Investment that
     reduced this clause (c) and (2) any amounts that increased the amount
     available as a Permitted Investment provided that with respect to any
     redesignation pursuant to this clause (iv) the Company shall deliver to the
     Trustee (I) in the case of any such redesignation involving aggregate fair
     market value greater than $2.0 million, a resolution of the Board of
     Directors set forth in an Officers' Certificate certifying such value or
     (II) in the case of any such redesignation involving aggregate fair market
     value greater than $10.0 million, an independ-

 
                                     -59-

     ent appraisal or valuation opinion issued by an accounting, appraisal or
     investment banking firm of national standing; provided that any amounts
     that increase this clause (c) shall not duplicatively increase amounts
     available as Permitted Investments.

          The foregoing provisions shall not prohibit: (i) the payment of any
dividend within 60 days after the date of declaration thereof, if at said date
of declaration such payment would have complied with the provisions of this
Indenture; (ii) the redemption, repurchase, retirement, defeasance or other
acquisition of any subordinated Indebtedness or Equity Interests of the Company
in exchange for, or out of the net cash proceeds of the substantially concurrent
sale (other than to a Restricted Subsidiary of the Company) of, other Equity
Interests of the Company (other than any Disqualified Stock); provided that the
amount of any such net cash proceeds that are utilized for any such redemption,
repurchase, retirement, defeasance or other acquisition shall be excluded from
clause (c)(ii) of the preceding paragraph; (iii) the defeasance, redemption,
repurchase or other acquisition of subordinated Indebtedness with the net cash
proceeds from an incurrence of Permitted Refinancing Indebtedness; (iv)
dividends or distributions by a Restricted Subsidiary of the Company so long as,
in the case of any dividend or distribution payable on or in respect of any
class or series of securities issued by a Restricted Subsidiary, the Company or
a Restricted Subsidiary receives at least its pro rata share of such dividend or
distribution in accordance with its Equity Interests in such class or series of
securities; (v) Investments in Unrestricted Subsidiaries having an aggregate
fair market value not to exceed the amount, at the time of such Investment,
substantially concurrently contributed in cash or Cash Equivalents to the common
equity capital of the Company after the date of the closing of the Acquisitions;
provided that any such amount contributed shall be excluded from the calculation
made pursuant to clause (c) of the preceding paragraph; (vi) the payment of
dividends on the Company's Common Stock, following the first public offering of
the Company's Common Stock after the date of the closing of the Acquisitions, of
up to 6% per annum of the net proceeds received by the Company in such public
offering, other than public offerings with respect to the Company's Common Stock
registered on Form S-8; (vii) the repurchase, redemption or other acquisition or
retirement for value of any Equity Interests of the Company or any Restricted
Subsidiary of the Company held by any present or former employee or director of
the Company (or any of its Restricted Subsidiaries), other than Equity Interests
held by the Principals or any of their Related Parties, pursuant to any
management equity subscription agreement or stock option agreement or any other
management or employee benefit plan; provided that (A) the aggregate price paid
for all such repurchased, redeemed, acquired or retired Equity Interests shall
not exceed $2.0 million in any calendar year (with unused amounts in any
calendar year being carried over to succeeding calendar years subject to a
maximum (without giving effect to the following proviso) of $5.0 million in any
calendar year); provided further that such amount in any calendar year

 
                                     -60-

may be increased by an amount not to exceed (x) the cash proceeds from the sale
of Equity Interests (not including Disqualified Stock) of the Company or a
Restricted Subsidiary to members of management and directors of the Company and
its Subsidiaries that occurs after the date of this Indenture, plus (y) the cash
proceeds of key-man life insurance policies received by the Company and its
Restricted Subsidiaries after the date of this Indenture, less (z) the amount of
any Restricted Payments previously made pursuant to clauses (x) and (y) of this
subparagraph (vii) and (B) no Default or Event of Default shall have occurred
and be continuing immediately after such transaction; and, provided further,
that cancellation of Indebtedness owing to the Company from members of
management of the Company or any of its Restricted Subsidiaries (other than the
Principals or any of their Related Parties) in connection with a repurchase of
Equity Interests of the Company or a Restricted Subsidiary pursuant to any
employment agreement or arrangement or any stock option or similar plan shall
not be deemed to constitute a Restricted Payment for purposes of this covenant
or any other provision of this Indenture; (viii) repurchases of Equity Interests
deemed to occur upon exercise of stock options if such Equity Interests
represent a portion of the exercise price of such options; (ix) the payment of
dividends or distributions to Holdings (I) pursuant to a tax allocation
agreement in effect on the date of this Indenture, in amounts required by
Holdings to pay income taxes; (II) in amounts required by Holdings to pay
administrative expenses not to exceed $500,000 in any calendar year; and (III)
in order to permit Holdings to repay Indebtedness under the Bridge Facilities;
and (x) the use of any and all Net Proceeds received from the sale of Assets
Held for Sale to repay Indebtedness outstanding under the Bridge Facilities.

          As of the date of this Indenture, all of the Company's Subsidiaries
shall be Restricted Subsidiaries. The Board of Directors may designate any
Restricted Subsidiary to be an Unrestricted Subsidiary if such designation would
not cause a Default. For purposes of making such determination, all outstanding
Investments by the Company and its Restricted Subsidiaries (except to the extent
repaid in cash) in the Subsidiary so designated will be deemed to be Restricted
Payments at the time of such designation and will reduce the amount available
for Restricted Payments under the first paragraph of this covenant. All such
outstanding Investments will be deemed to constitute Investments in an amount
equal to the fair market value of such Investments at the time of such
designation. Such designation will only be permitted if such Restricted Payment
would be permitted at such time and if such Restricted Subsidiary otherwise
meets the definition of an Unrestricted Subsidiary.

          If, at any time, any Unrestricted Subsidiary would fail to meet the
requirements in the definition of "Unrestricted Subsidiary" as an Unrestricted
Subsidiary, it shall thereafter cease to be an Unrestricted Subsidiary for
purposes of this Indenture and any Indebtedness of such Subsidiary shall be
deemed to be incurred by a Restricted Subsidiary of the Company as of such date
(and, if such Indebtedness is not permitted to be incurred as of

 
                                     -61-

such date under the covenant described under Section 4.09, the Company shall be
in default of such covenant). The Board of Directors of the Company may at any
time designate any Unrestricted Subsidiary to be a Restricted Subsidiary;
provided that such designation shall be deemed to be an incurrence of
Indebtedness by a Restricted Subsidiary of the Company of any outstanding
Indebtedness of such Unrestricted Subsidiary and such designation shall only be
permitted if (i) such Indebtedness is permitted under the covenant described
under Section 4.09, calculated on a pro forma basis as if such designation had
occurred at the beginning of the four-quarter reference period, and (ii) no
Default or Event of Default would be in existence following such designation.

          The amount of all Restricted Payments (other than cash) shall be the
fair market value on the date of the Restricted Payment of the asset(s) or
securities proposed to be transferred or issued by the Company or such
Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment.
The fair market value of any non-cash Restricted Payment or any adjustment made
pursuant to clause (c) of the first paragraph of this covenant shall be
determined by the Board of Directors whose resolution with respect thereto 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 $10.0 million. Not later
than the date of making any Restricted Payment, the Company shall deliver to the
Trustee an Officers' Certificate stating that such Restricted Payment is
permitted and setting forth the basis upon which the calculations required by
Section 4.07 were computed.

          If any Restricted Investment is sold or otherwise liquidated or repaid
or any dividend or payment is received by the Company or a Restricted Subsidiary
and such amounts may be credited to clause (c) of the first paragraph of this
covenant, then such amounts will be credited only to the extent of amounts not
otherwise included in Consolidated Net Income and that do not otherwise increase
the amount available as a Permitted Investment.

          SECTION 4.08.  Dividend and Other Payment Restrictions Affecting
                         Restricted Subsidiaries.
                         -------------------------------------------------   

          The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to
exist or become effective any encumbrance or restriction on the ability of any
Restricted Subsidiary to (i)(a) pay dividends or make any other distributions to
the Company or any of its Restricted Subsidiaries (1) on its Capital Stock or
(2) with respect to any other interest or participation in, or measured by, its
profits, or (b) pay any Indebtedness owed to the Company or any of its
Restricted Subsidiaries, (ii) make loans or advances to the Company or any of
its Restricted Subsidiaries or (iii) transfer any of its properties or assets to
the Company or any of its Re-

 
                                     -62-

stricted Subsidiaries. However, the foregoing restrictions shall not apply to
encumbrances or restrictions existing under or by reason of (a) Existing
Indebtedness as in effect on the date of this Indenture, (b) the Senior Credit
Facilities as in effect as of the date of this Indenture, and any amendments,
modifications, restatements, renewals, increases, supplements, refundings,
replacements or refinancings thereof, provided that such amendments,
modifications, restatements, renewals, increases, supplements, refundings,
replacement or refinancings are no more restrictive, taken as a whole, with
respect to such dividend and other payment restrictions than those contained in
the Senior Credit Facilities as in effect on the date of this Indenture, (c)
this Indenture, the Senior Subordinated Note Indenture, the Notes and the Senior
Subordinated Notes, (d) applicable law or any applicable rule, regulation or
order, (e) any instrument governing Indebtedness or Capital Stock of a Person
acquired by the Company or any of its Restricted Subsidiaries as in effect at
the time of such acquisition (except to the extent such Indebtedness was
incurred in connection with or in contemplation of such acquisition), which
encumbrance or restriction is not applicable to any Person, or the properties or
assets of any Person, other than the Person, or the property or assets of the
Person, so acquired, provided that, in the case of Indebtedness, such
Indebtedness was permitted by the terms of this Indenture to be incurred, (f)
customary non-assignment provisions in leases and other agreements entered into
in the ordinary course of business and consistent with past practices, (g)
purchase money obligations for property acquired in the ordinary course of
business that impose restrictions of the nature described in clause (iii) above
on the property so acquired, (h) any agreement for the sale of a Restricted
Subsidiary that restricts distributions by that Restricted Subsidiary pending
its sale, (i) Permitted Refinancing Indebtedness, provided that the restrictions
contained in the agreements governing such Permitted Refinancing Indebtedness
are no more restrictive, taken as a whole, than those contained in the
agreements governing the Indebtedness being refinanced, (j) secured Indebtedness
otherwise permitted to be incurred pursuant to the provisions of the covenant
described under Section 4.12 that limits solely the right of the debtor to
dispose of the assets securing such Indebtedness, (k) provisions with respect to
the disposition or distribution of assets or property in joint venture
agreements and other similar agreements entered into in the ordinary course of
business, (l) restrictions on cash or other deposits or net worth imposed by
customers or lessors under contracts or leases entered into in the ordinary
course of business and (m) any encumbrances or restrictions imposed by any
amendments, modifications, restatements, renewals, increases, supplements,
refundings, replacements or refinancings of the contracts, instruments or
obligations referred to in clauses (a) through (l) above, provided that such
amendments, modifications, restatements, renewals, increases, supplements,
refundings, replacements or refinancings are, in the good faith judgment of the
Company's Board of Directors, not materially more restrictive in the aggregate
with respect to such dividend and other payment restrictions than those
(considered as a whole) contained in the dividend or other payment restrictions
prior to such amend-

 
                                     -63-

ment, modification, restatement, renewal, increase, supplement, refunding,
replacement or refinancing.

          SECTION 4.09.   Incurrence of Indebtedness and Issuance 
                          of Preferred Stock.
                          ------------------------------------------

          The Company shall not, and shall not permit any of its Subsidiaries
to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise
become directly or indirectly liable, contingently or otherwise, with respect to
(collectively, ''incur'') any Indebtedness (including Acquired Debt) and the
Company shall not issue any Disqualified Stock and shall not permit any of its
Subsidiaries to issue any shares of preferred stock; provided, however, that the
Company may incur Indebtedness (including Acquired Debt) or issue shares of
Disqualified Stock and the Subsidiary Guarantors may incur Indebtedness or issue
Disqualified Stock or preferred stock if the Fixed Charge Coverage Ratio for the
Company's most recently ended four full fiscal quarters for which internal
financial statements are available immediately preceding the date on which such
additional Indebtedness is incurred or such Disqualified Stock or preferred
stock is issued would have been at least 2.0 to 1.0, determined on a pro forma
basis (including a pro forma application of the net proceeds therefrom), as if
the additional Indebtedness had been incurred, or the Disqualified Stock or
preferred stock had been issued, as the case may be, at the beginning of such
four-quarter period.

          The provisions of the first paragraph of this covenant shall not apply
to the incurrence of any of the following items of Indebtedness (collectively,
"Permitted Debt"):

             (i)    the incurrence by the Company of Indebtedness under Credit
     Facilities (and the Guarantee thereof by the Subsidiary Guarantors);
     provided that the aggregate principal amount of all Indebtedness
     outstanding under this clause (i) after giving effect to such incurrence
     does not exceed an amount equal to $875.0 million (with letters of credit
     being deemed to have a principal amount equal to the maximum potential
     liability of the Company and its Restricted Subsidiaries thereunder) less
     the amount of proceeds of Asset Sales applied to repay any such term
     Indebtedness or revolving Indebtedness if such repayment of revolving
     Indebtedness resulted in a corresponding commitment reduction (excluding
     any such payments to the extent refinanced at the time of repayment);

             (ii)   the incurrence by the Company and its Subsidiaries of
     Existing Indebtedness, the Senior Subordinated Notes issued in the Offering
     and the Guarantees thereof;

 
                                     -64-

             (iii)  (A) the guarantee by the Company or any of the Subsidiary
     Guarantors of Indebtedness of the Company or a Restricted Subsidiary of the
     Company or (B) the incurrence of Indebtedness of a Restricted Subsidiary to
     the extent that such Indebtedness is supported by a letter of credit, in
     each case that was permitted to be incurred by another provision of this
     covenant;

             (iv)   the incurrence by the Company or any of its Restricted
     Subsidiaries of Indebtedness (including Capital Lease Obligations) to
     finance the acquisition (including by direct purchase, by lease or
     indirectly by the acquisition of the Capital Stock of a Person that becomes
     a Restricted Subsidiary as a result of such acquisition) or improvement of
     assets or property (real or personal) in an aggregate principal amount
     which, when aggregated with the principal amount of all other Indebtedness
     then outstanding pursuant to this clause (iv) and including all Permitted
     Refinancing Indebtedness incurred to refund, refinance or replace any
     Indebtedness incurred pursuant to this clause (iv), does not exceed an
     amount equal to 5% of Total Assets at the time of such incurrence;

             (v)    the incurrence by the Company or any of its Restricted
     Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the
     net proceeds of which are used to refund, refinance or replace Indebtedness
     (other than intercompany Indebtedness) that was permitted by this Indenture
     to be incurred under the first paragraph hereof or clauses (ii), (iii) or
     (iv) of this paragraph;

             (vi)   the incurrence by the Company or any of its Restricted
     Subsidiaries of intercompany Indebtedness between or among the Company and
     any of its Restricted Subsidiaries; provided, however, that (i) if the
     Company is the obligor on such Indebtedness, such Indebtedness is expressly
     subordinated to the prior payment in full in cash of all Obligations with
     respect to the Notes and (ii)(A) any subsequent issuance or transfer of
     Equity Interests that results in any such Indebtedness being held by a
     Person other than the Company or a Restricted Subsidiary thereof and (B)
     any sale or other transfer of any such Indebtedness to a Person that is not
     either the Company or a Restricted Subsidiary thereof shall be deemed, in
     each case, to constitute an incurrence of such Indebtedness by the Company
     or such Restricted Subsidiary, as the case may be, that was not permitted
     by this clause (vi);

             (vii)  the incurrence by the Company or any of its Restricted
     Subsidiaries of Hedging Obligations that are incurred in the ordinary
     course of business for the purpose of risk management and not for the
     purpose of speculation;

             (viii) the incurrence by the Company's Unrestricted Subsidiaries
     of Non-Recourse Debt, provided, however, that if any such Indebtedness
     ceases to be Non-

 
                                     -65-

     Recourse Debt of an Unrestricted Subsidiary, such event shall be deemed to
     constitute an incurrence of Indebtedness by a Restricted Subsidiary of the
     Company that was not permitted by this clause (viii), and the issuance of
     preferred stock by Unrestricted Subsidiaries;

             (ix)   the incurrence of Indebtedness solely in respect of
     performance, surety and similar bonds or completion or performance
     guarantees (including, without limitation, performance guarantees pursuant
     to coal supply agreements or equipment leases and including letters of
     credit issued in support of such performance, surety and similar bonds), to
     the extent that such incurrence does not result in the incurrence of any
     obligation for the payment of borrowed money to others;

             (x)    the incurrence of Indebtedness arising from agreements of
     the Company or a Restricted Subsidiary providing for indemnification,
     adjustment of purchase price or similar obligations, in each case, incurred
     or assumed in connection with the disposition of any business, assets or a
     Subsidiary; provided, however, that (i) such Indebtedness is not reflected
     on the balance sheet of the Company or any Restricted Subsidiary
     (contingent obligations referred to in a footnote to financial statements
     and not otherwise reflected on the balance sheet shall not be deemed to be
     reflected on such balance sheet for purposes of this clause (i)) and (ii)
     the maximum assumable liability in respect of all such Indebtedness shall
     at no time exceed the gross proceeds including noncash proceeds (the fair
     market value of such noncash proceeds being measured at the time received
     and without giving effect to any subsequent changes in value) actually
     received by the Company and its Restricted Subsidiaries in connection with
     such disposition; and

             (xi)   the incurrence by the Company or any of its Restricted
     Subsidiaries of additional Indebtedness in an aggregate principal amount
     (or accreted value, as applicable) at any time outstanding, including all
     Permitted Refinancing Indebtedness incurred to refund, refinance or replace
     any Indebtedness incurred pursuant to this clause (xi), not to exceed the
     greater of (i) (x) $25.0 million and (y) 1% of Total Assets if incurred on
     or prior to December 15, 2000 or (ii) (x) $50.0 million and (y) 2% of Total
     Assets if incurred thereafter.

             The Company shall not incur, and shall not permit its Restricted
Subsidiaries to incur, any Indebtedness (including Permitted Debt) that is
contractually subordinated in right of payment to any other Indebtedness of the
Company or such Restricted Subsidiary unless such Indebtedness is also
contractually subordinated in right of payment to the Notes, or the Subsidiary
Guarantees, as the case may be, on substantially identical terms; provided,
however, that no Indebtedness of the Company or any Restricted Subsidiary shall

 
                                     -66-

be deemed to be contractually subordinated in right of payment to any other
Indebtedness of the Company or any Restricted Subsidiary solely by virtue of
being unsecured.

          For purposes of determining compliance with this covenant, in the
event that an item of Indebtedness meets the criteria of more than one of the
categories of Permitted Debt described in clauses (i) through (xi) above or is
entitled to be incurred pursuant to the first paragraph of this covenant, the
Company shall, in its sole discretion, classify or reclassify such item of
Indebtedness in any manner that complies with this covenant. Accrual of
interest, accretion or amortization of original issue discount, the payment of
interest on any Indebtedness in the form of additional Indebtedness with the
same terms, and the payment of dividends on Disqualified Stock in the form of
additional shares of the same class of Disqualified Stock, shall not be deemed
to be an incurrence of Indebtedness or an issuance of Disqualified Stock for
purposes of this covenant; provided, in each such case, that the amount thereof
is included in Fixed Charges of the Company as accrued.

          SECTION 4.10.   Asset Sales.
                          ----------- 

          The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, consummate an Asset Sale unless (i) the Company (or the
Restricted Subsidiary, as the case may be) receives consideration at the time of
such Asset Sale at least equal to the fair market value as determined in good
faith by the Company (evidenced by a resolution of the Board of Directors set
forth in an Officers' Certificate delivered to the Trustee with respect to any
Asset Sale determined to have a value greater than $25.0 million) of the assets
or Equity Interests issued or sold or otherwise disposed of and (ii) except in
the case of Assets Held for Sale, at least 75% of the consideration therefor
received by the Company or such Subsidiary is in the form of cash, Cash
Equivalents or Marketable Securities; provided that the following amounts shall
be deemed to be cash: (w) any liabilities (as shown on the Company's or such
Restricted Subsidiary's most recent balance sheet), of the Company or any
Restricted Subsidiary (other than contingent liabilities and liabilities 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 customary novation
agreement that releases the Company or such Restricted Subsidiary from further
liability, (x) any securities, notes or other obligations received by the
Company or any such Restricted Subsidiary from such transferee that are
contemporaneously (subject to ordinary settlement periods) converted by the
Company or such Restricted Subsidiary into cash (to the extent of the cash
received), (y) any Designated Noncash Consideration received by the Company or
any of its Restricted Subsidiaries in such Asset Sale; provided that the
aggregate fair market value (as determined above) of such Designated Noncash
Consideration, taken together with the fair market value at the time of receipt
of all other Designated Noncash Consideration received pursuant to this clause
(y) less the amount of Net Proceeds previously realized in cash from prior
Designated Noncash Consideration is less than 5% of Total Assets at the time of
the 

 
                                     -67-

receipt of such Designated Noncash Consideration (with the fair market value
of each item of Designated Noncash Consideration being measured at the time
received and without giving effect to subsequent changes in value) and (z)
Additional Assets received in an exchange of assets transaction.

          Within 360 days after the receipt of any cash Net Proceeds from an
Asset Sale, the Company or such Restricted Subsidiary, at its option, may apply
such cash Net Proceeds, at its option, (i) in the case of an Asset Sale of
Assets Held for Sale, toward the repayment of the Bridge Facilities and (ii) in
the case of all other Asset Sales, (a) to repay Indebtedness of the Company or
any Restricted Subsidiary that is not subordinated in right of payment to the
Notes or to repay debt under one or more Credit Facilities and, if such debt is
revolving debt, to effect a corresponding commitment reduction thereunder, (b)
to the acquisition of all or a portion of the assets of, or a majority of the
Voting Stock of, another Permitted Business, the making of a capital expenditure
or the acquisition of other assets or Investments that are used or useful in a
Permitted Business or (c) to an Investment in Additional Assets. Any cash Net
Proceeds from Asset Sales that are not applied or invested as provided in the
first sentence of this paragraph shall be deemed to constitute "Excess
Proceeds." When the aggregate amount of Excess Proceeds exceeds $15.0 million,
the Company will be required to make an offer to all Holders of Notes and all
holders of other Indebtedness that ranks pari passu with the Notes containing
provisions similar to those set forth in this Indenture with respect to offers
to purchase or redeem with the proceeds of sales of assets (an "Asset Sale
Offer") to purchase the maximum principal amount of Notes and such other
Indebtedness that may be purchased out of the Excess Proceeds, at an offer price
in cash in an amount equal to 100% of the principal amount thereof plus accrued
and unpaid interest and Liquidated Damages thereon, if any, to the date of
purchase, in accordance with the procedures set forth in this Indenture and such
other Indebtedness. To the extent that any Excess Proceeds remain after
consummation of an Asset Sale Offer, the Company may use such Excess Proceeds
for any purpose not otherwise prohibited by this Indenture. If the aggregate
principal amount of Notes and such other Indebtedness tendered into such Asset
Sale Offer surrendered by Holders thereof exceeds the amount of Excess Proceeds,
the Trustee shall select the Notes and such other Indebtedness to be purchased
on a pro rata basis. Upon completion of such offer to purchase, the amount of
Excess Proceeds shall be reset at zero.

          SECTION 4.11.   Transactions with Affiliates.
                          ---------------------------- 

          The Company shall not, and shall not permit any of its Subsidiaries
to, make any payment to, or sell, lease, transfer or otherwise dispose of any of
its properties or assets to, or purchase any property or assets from, or enter
into or make or amend any transaction, contract, agreement, understanding, loan,
advance or guarantee with, or for the benefit of, any Affiliate (each of the
foregoing, an "Affiliate Transaction"), unless (i) such 

 
                                     -68-

Affiliate Transaction is on terms that are materially no less favorable to the
Company or the relevant Subsidiary than those that would have been obtained in a
comparable transaction by the Company or such Subsidiary with an unrelated
Person and (ii) the Company delivers to the Trustee (a) with respect to any
Affiliate Transaction or series of related Affiliate Transactions involving
aggregate consideration in excess of $2.0 million, a resolution of the Board of
Directors set forth in an Officers' Certificate certifying that such Affiliate
Transaction complies with clause (i) above and that such Affiliate Transaction
has been approved by a majority of the disinterested members of the Board of
Directors and (b) with respect to any Affiliate Transaction or series of related
Affiliate Transactions involving aggregate consideration in excess of $10.0
million, an opinion as to the fairness to the Holders of such Affiliate
Transaction from a financial point of view issued by an accounting, appraisal or
investment banking firm of national standing. Notwithstanding the foregoing, the
following items shall not be deemed to be Affiliate Transactions: (i)
transactions entered into pursuant to the terms of (a) the Haulage and Delivery
Agreement, (b) the MMI Service Agreement, (c) the MMI Leases, (d) the Bowie
Sales Agency Agreement, (e) the Manufacture and Service Agreement and (f) the
Technology Sharing Agreement, each as in effect on the date of this Indenture or
as thereafter amended, provided any such amendment does not materially and
adversely effect the rights of the Holders of the Notes under this Indenture,
(ii) any employment agreement or arrangement entered into by the Company or any
of its Subsidiaries or any employee benefit plan available to employees of the
Company and its Subsidiaries generally, in each case in the ordinary course of
business and consistent with the past practice of the Company or such
Subsidiary, (iii) transactions between or among the Company and/or its
Subsidiaries, (iv) payment of reasonable directors fees to Persons who are not
otherwise Affiliates of the Company, (v) Restricted Payments that are permitted
by the provisions of Section 4.07 or pursuant to the definition of Permitted
Investments, (vi) indemnification payments made to officers, directors and
employees of the Company or any Restricted Subsidiary pursuant to charter,
bylaw, statutory or contractual provisions; and (vii) transactions pursuant to
the terms of the Transaction Documents in effect on the dates of the closings of
the Acquisitions.

          SECTION 4.12.   Liens.
                          ----- 

          The Company shall not and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly, create, incur, assume or otherwise
cause or suffer to exist or become effective any Lien of any kind (other than
Permitted Liens) upon any of their property or assets, now owned or hereafter
acquired, unless all payments due under this Indenture and the Notes are secured
on an equal and ratable basis with the obligations so secured until such time as
such obligations are no longer secured by a Lien.

 
                                     -69-

          SECTION 4.13.   Business Activities.
                          ------------------- 

          The Company shall not, and shall not permit any Restricted Subsidiary
to, engage in any business other than Permitted Businesses, except to such
extent as would not be material to the Company and its Restricted Subsidiaries
taken as a whole.

          SECTION 4.14.   Corporate Existence.
                          ------------------- 

          Subject to Article 5 hereof, each Issuer shall do or cause to be done
all things necessary to preserve and keep in full force and effect (i) its
corporate existence, and the corporate, partnership or other existence of each
of its Subsidiaries, in accordance with the respective organizational documents
(as the same may be amended from time to time) of it or any such Subsidiary and
(ii) the rights (charter and statutory), licenses and franchises of it and its
Subsidiaries; provided, however, that each Issuer shall not be required to
preserve any such right, license or franchise, or the corporate, partnership or
other existence of any of its Subsidiaries, if its Board of Directors shall
determine that the preservation thereof is no longer desirable in the conduct of
the business of it and its Subsidiaries, taken as a whole, and that the loss
thereof is not adverse in any material respect to the Holders of the Notes.

          SECTION 4.15.   Offer to Repurchase Upon Change of Control.
                          ------------------------------------------ 

          (a)  Upon the occurrence of a Change of Control, each Holder of Notes
will have the right to require the Company to repurchase all or any part (equal
to $1,000 or an integral multiple thereof) of such Holder's Notes pursuant to
the offer described below (the "Change of Control Offer") at an offer price in
cash equal to 101% of the aggregate principal amount thereof plus accrued and
unpaid interest and Liquidated Damages thereon, if any, to the date of purchase
(the "Change of Control Payment"). Within ten days following any Change of
Control, the Company shall mail a notice to each Holder describing the
transaction or transactions that constitute the Change of Control and offering
to repurchase Notes on the date specified in such notice, which date shall be no
earlier than 30 days and no later than 60 days from the date such notice is
mailed (the "Change of Control Payment Date"), pursuant to the procedures
required by this Indenture and described in such notice. The Company shall
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 the Notes as a
result of a Change of Control.

          On the Change of Control Payment Date, the Company shall, to the
extent lawful, (1) accept for payment all Notes or portions thereof properly
tendered pursuant to the Change of Control Offer, (2) deposit with the Paying
Agent an amount equal to the 

 
                                     -70-

Change of Control Payment in respect of all Notes or portions thereof so
tendered and (3) deliver or cause to be delivered to the Trustee the Notes so
accepted together with an Officers' Certificate stating the aggregate principal
amount of Notes or portions thereof being purchased by the Company. The Paying
Agent will promptly mail to each Holder of Notes so tendered the Change of
Control Payment for such Notes, and the Trustee will promptly authenticate and
mail (or cause to be transferred by book entry) to each Holder a new Note equal
in principal amount to any unpurchased portion of the Notes surrendered, if any;
provided that each such new Note will be in a principal amount of $1,000 or an
integral multiple 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.

          (b)  The Company will not be required to make a Change of Control
Offer upon a Change of Control if a third party makes the Change of Control
Offer in the manner, at the times and otherwise in compliance with the
requirements set forth in this Indenture applicable to a Change of Control Offer
made by the Company and purchases all Notes validly tendered and not withdrawn
under such Change of Control Offer.

          SECTION 4.16.   Incurrence of Senior Indebtedness.
                          --------------------------------- 

          The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly, incur any Senior Indebtedness (other
than (x) secured Indebtedness pursuant to the Senior Credit Facilities not in
excess of $875.0 million at any one time outstanding thereunder and (y)
Indebtedness incurred pursuant to clauses (iii) through (xi) of the definition
of Permitted Debt); provided, however, that the Company or any of its Restricted
Subsidiaries may incur Senior Indebtedness (including Acquired Debt that is
Senior Indebtedness) if the Company's Debt to Cash Flow Ratio at the time of
incurrence of such Senior Indebtedness, after giving pro forma effect to such
incurrence as of such date and to the use of proceeds therefrom as if the same
had occurred at the beginning of the most recently ended four full fiscal
quarter period of the Company for which internal financial statements are
available, would have been no greater than 3.0 to 1; provided, further, that any
unsecured Senior Indebtedness to be issued in compliance with this proviso must
have a maturity date or mandatory redemption or repurchase date which is the
same as or later than the maturity date of the Notes.

          SECTION 4.17.   Limitation on Issuances and Sales of Equity 
                          Interests in Wholly Owned Subsidiaries.
                          --------------------------------------------

          The Company (i) shall not, and shall not permit any Wholly Owned
Restricted Subsidiary of the Company to, transfer, convey, sell, lease or
otherwise dispose of any Equity Interests in a Wholly Owned Restricted
Subsidiary of the Company to any Person (other than the Company or a Wholly
Owned Subsidiary of the Company), unless (1) 

 
                                     -71-

such transfer, conveyance, sale, lease or other disposition is of all the Equity
Interests in such Wholly Owned Restricted Subsidiary and (2) the cash Net
Proceeds from such transfer, conveyance, sale, lease or other disposition are
applied in accordance with the covenant described above under Section 4.10, and
(ii) shall not permit any Wholly Owned Restricted Subsidiary of the Company to
issue any of its Equity Interests (other than, if necessary, shares of its
Capital Stock constituting directors' qualifying shares) to any Person other
than to the Company or a Wholly Owned Restricted Subsidiary of the Company.

          SECTION 4.18.   Payments for Consent.
                          -------------------- 

          Neither the Company nor any of its Restricted Subsidiaries shall,
directly or indirectly, pay or cause to be paid any consideration, whether by
way of interest, fee or otherwise, to any Holder of any Notes for or as an
inducement to any consent, waiver or amendment of any of the terms or provisions
of this Indenture or the Notes unless such consideration is offered to be paid
or is paid to all Holders of the Notes that consent, waive or agree to amend in
the time frame set forth in the solicitation documents relating to such consent,
waiver or agreement.

          SECTION 4.19.   Additional Subsidiary Guarantees.
                          -------------------------------- 

          If the Company or any of its Domestic Subsidiaries shall acquire or
create another Domestic Subsidiary after the date of this Indenture and such
Domestic Subsidiary provides a guarantee of the Senior Credit Facilities, then
such newly acquired or created Domestic Subsidiary shall execute a supplemental
indenture in form and substance satisfactory to the Trustee providing that such
Domestic Subsidiary shall become a Subsidiary Guarantor under this Indenture,
provided, however, this covenant shall not apply to any Domestic Subsidiary that
has been properly designated as an Unrestricted Subsidiary in accordance with
this Indenture for so long as it continues to constitute an Unrestricted
Subsidiary.

by or surviving any such consolidation or merger (if other than the Company) or
the entity or Person to which such sale, assignment, transfer, lease, conveyance
or other disposition shall have been made assumes all the obligations of the
Company under the Registration Rights Agreement, the Notes and this Indenture
pursuant to a supplemental indenture in a form reasonably satisfactory to the
Trustee; (iii) immediately after such transaction no Default or Event of Default
exists; and (iv) except in the case of a merger of the Company with or into a
Wholly Owned Restricted Subsidiary of the Company, immediately after giving pro
forma effect to such transaction, as if such transaction had occurred at the
beginning of the applicable four-quarter period, (A) the entity surviving such
consolidation or merger would be permitted to incur at least $1.00 of additional
Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in the
first paragraph of the covenant described under Section 4.09 or (B) the Fixed
Charge Coverage Ratio for the Company or the entity or Person formed by or
surviving any such consolidation or merger (if other than the Company), or to
which such sale, assignment, transfer, lease, conveyance or other disposition
shall have been made would, immediately after giving pro forma effect thereto as
if such transaction had occurred at the beginning of the applicable four-quarter
period, not be less than such Fixed Charge Coverage Ratio for the Company and
its Restricted Subsidiaries immediately prior to such transaction. The Company
may not, directly or indirectly, lease all or substantially all of its
properties or assets, in one or more related transactions, to any other Person.
The provisions of this covenant shall not be applicable to a sale, assignment,
transfer, conveyance or other disposition of assets between or among the Company
and its Restricted Subsidiaries.

          Notwithstanding the foregoing clause (iv), (i) any Restricted
Subsidiary may consolidate with, merge into or transfer all or part of its
properties and assets to the Company and (ii) the Company may merge with an
Affiliate that has no significant assets or liabilities and was formed solely
for the purpose of changing the jurisdiction of organization of the Company in
another State of the United States or the form of organization of the Company so
long as the amount of Indebtedness of the Company and its Restricted
Subsidiaries is not increased thereby and provided that the successor assumes
all the obligations of the Company under the Registration Rights Agreement, the
Notes and this Indenture pursuant to a supplemental indenture in a form
reasonably satisfactory to the Trustee.

          SECTION 5.02.   Successor Corporation Substituted.
                          --------------------------------- 

          Upon any consolidation or merger, or any sale, assignment, transfer,
lease, conveyance or other disposition of all or substantially all of the assets
of either Issuer in 

 
                                     -73-

accordance with Section 5.01 hereof, the successor corporation formed by such
consolidation or into or with which such Issuer is merged or to which such sale,
assignment, transfer, lease, conveyance or other disposition is made shall
succeed to, and be substituted for (so that from and after the date of such
consolidation, merger, sale, lease, conveyance or other disposition, the
provisions of this Indenture referring to such "Issuer" shall refer instead to
the successor corporation and not to such Issuer), and may exercise every right
and power of such Issuer under this Indenture with the same effect as if such
successor Person had been named as such Issuer herein; provided, however, that
the predecessor Issuer shall not be relieved from the obligation to pay the
principal of and interest on the Notes except in the case of a sale of all of
such Issuer's assets that meets the requirements of Section 5.01 hereof.


                                  ARTICLE SIX

                             DEFAULTS AND REMEDIES

          SECTION 6.01.   Events of Default.
                          ----------------- 

          Each of the following constitutes an Event of Default:

          (a)     default for 30 days in the payment when due of interest on, or
Liquidated Damages, if any, with respect to, the Notes;

          (b)     default in payment when due of the principal of or premium, if
any, on the Notes;

          (c)     failure by the Company or any of its Subsidiaries to make the
offer required or to purchase any of the Notes as required under the provisions
described under Section 4.10 or Section 4.15;

          (d)     failure by the Company or any of its Subsidiaries for 30 days
after notice to comply with the provisions of Section 4.07 or Section 4.09, or
failure by the Company or any of its Subsidiaries for 60 days after notice to
comply with any of its other agreements in this Indenture or the Notes;

          (e)     default under any mortgage, indenture or instrument under
which there may be issued or by which there may be secured or evidenced any
Indebtedness for money borrowed by the Company or any of its Restricted
Subsidiaries (or the payment of which is guaranteed by the Company or any of its
Restricted Subsidiaries) whether such Indebtedness or guarantee now exists, or
is created after the date of this Indenture, which

 
                                     -74-

default (a) is caused by a failure to pay principal of or premium, if any, or
interest on such Indebtedness prior to the expiration of the grace period
provided in such Indebtedness on the date of such default (a "Payment Default")
or (b) results in the acceleration of such Indebtedness prior to its express
maturity and, in each case, the principal amount of any such Indebtedness,
together with the principal amount of any other such Indebtedness under which
there has been a Payment Default or the maturity of which has been so
accelerated, aggregates $25.0 million or more;

          (f)     failure by the Company or any of its Restricted Subsidiaries
or any group of Restricted Subsidiaries that, taken as a whole, would be a
Significant Subsidiary to pay final judgments aggregating in excess of $25.0
million, which judgments are not paid, discharged or stayed for a period of 60
days;

          (g)     except as permitted by this Indenture, any Guarantee of the
Notes shall be held in any judicial proceeding to be unenforceable or invalid or
shall cease for any reason to be in full force and effect or any Guarantor, or
any Person acting on behalf of any Guarantor, shall deny or disaffirm its
obligations under its Guarantee of the Notes;

          (h)     an Issuer or any of its Significant Subsidiaries that are
Restricted Subsidiaries or any group of Restricted Subsidiaries that, taken as a
whole, would be a Significant Subsidiary pursuant to or within the meaning of
Bankruptcy Law:

             (i)  commences a voluntary case,

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

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

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

             (v)  generally is not paying its debts as they become due; or

          (i)     a court of competent jurisdiction enters an order or decree
under any Bankruptcy Law that:

             (i)  is for relief against an Issuer or any of its Significant
     Subsidiaries that are Restricted Subsidiaries or any group of Restricted
     Subsidiaries that, taken as a whole, would be a Significant Subsidiary in
     an involuntary case;

 
                                     -75-

            (ii)  appoints a custodian of an Issuer or any of its Significant
     Subsidiaries that are Restricted Subsidiaries or any group of Restricted
     Subsidiaries that, taken as a whole, would be a Significant Subsidiary or
     for all or substantially all of the property of an Issuer or any of its
     Significant Subsidiaries that are Restricted Subsidiaries or any group of
     Restricted Subsidiaries that, taken as a whole, would be a Significant
     Subsidiary; or

           (iii)  orders the liquidation of an Issuer or any of its
     Significant Subsidiaries that are Restricted Subsidiaries or any group of
     Restricted Subsidiaries that, taken as a whole, would be a Significant
     Subsidiary;

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

          SECTION 6.02.   Acceleration.
                          ------------ 

          If any Event of Default occurs and is continuing, the Trustee or the
Holders of at least 25% in principal amount of the then outstanding Notes may
declare all the Notes to be due and payable immediately. Notwithstanding the
foregoing, in the case of an Event of Default arising from certain events of
bankruptcy or insolvency, with respect to the Company, any Significant
Subsidiary that is a Restricted Subsidiary or any group of Restricted
Subsidiaries that, taken together, would constitute a Significant Subsidiary,
all outstanding Notes will become due and payable without further action or
notice. Holders of the Notes may not enforce this Indenture or the Notes except
as provided in this Indenture. Subject to certain limitations, Holders of a
majority in principal amount of the then outstanding Notes may by written notice
to the Trustee direct the Trustee in its exercise of any trust or power.

          In the case of any Event of Default occurring by reason of any willful
action (or inaction) taken (or not taken) by or on behalf of the Company with
the intention of avoiding payment of the premium that the Company would have had
to pay if the Company then had elected to redeem the Notes pursuant to the
optional redemption provisions of this Indenture, an equivalent premium shall
also become and be immediately due and payable to the extent permitted by law
upon the acceleration of the Notes. If an Event of Default occurs prior to
December 15, 2002 by reason of any willful action (or inaction) taken (or not
taken) by or on behalf of the Company with the intention of avoiding paying the
premium upon redemption of the Notes prior to December 15, 2002, then the
premium specified in the event of an optional redemption using the net cash
proceeds of an Equity Offering shall also become immediately due and payable to
the extent permitted by law upon the acceleration of the Notes.

 
                                     -76-

          SECTION 6.03.   Other Remedies.
                          -------------- 

          If an Event of Default occurs and is continuing, the Trustee may
pursue any available remedy to collect the payment of principal, premium, if
any, and 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 of a Note in exercising any right or
remedy accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default.  All remedies
are cumulative to the extent permitted by law.

          SECTION 6.04.   Waiver of Past Defaults.
                          ----------------------- 

          The Holders of a majority in aggregate principal amount of the Notes
then outstanding by notice to the Trustee may on behalf of the Holders of all of
the Notes waive any existing Default or Event of Default and its consequences
under this Indenture, except a continuing Default or Event of Default in the
payment of the principal of, premium and Liquidated Damages, if any, or interest
on, the Notes (including in connection with an offer to purchase) (provided,
however, that the Holders of a majority in aggregate principal amount of the
then outstanding Notes may rescind an acceleration and its consequences,
including any related payment default that resulted from such acceleration).
Upon any such waiver, such Default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured for every purpose
of this Indenture; but no such waiver shall extend to any subsequent or other
Default or impair any right consequent thereon.

          SECTION 6.05.   Control by Majority.
                          ------------------- 

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

          SECTION 6.06.   Limitation on Suits.
                          ------------------- 

          Holders of the Notes may not enforce this Indenture or the Notes
except as provided herein. A Holder of a Note may pursue a remedy with respect
to this Indenture or the Notes only if:

 
                                     -77-

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

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

          (c)  such Holder of a Note or Holders of Notes offer and, if
     requested, provide to the Trustee indemnity satisfactory to the Trustee
     against any loss, liability or expense;

          (d)  the Trustee does not comply with the request within 60 days after
     receipt of the request and the offer and, if requested, the provision of
     indemnity; and

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

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

          SECTION 6.07.   Rights of Holders of Notes to Receive Payment.
                          --------------------------------------------- 

          Notwithstanding any other provision of this Indenture, the right of
any Holder of a Note to receive payment of principal, premium and Liquidated
Damages, if any, and interest on the Note, on or after the respective due dates
expressed in the Note (including in connection with an offer to purchase), 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 specified in Section 6.01(a) or (b) occurs and
is continuing, the Trustee is authorized to recover judgment in its own name and
as trustee of an express trust against the Issuers for the whole amount of
principal of, premium and Liquidated Damages, if any, and interest remaining
unpaid on the Notes and interest on overdue principal and, to the extent lawful,
interest and such further amount as shall be sufficient to cover the costs and
expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel.

 
                                     -78-

          SECTION 6.09.   Trustee May File Proofs of Claim.
                          -------------------------------- 

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

          SECTION 6.10.   Priorities.
                          ---------- 

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

          First:  to the Trustee, its agents and attorneys for amounts due under
Section 7.07 hereof, including, without limitation, payment of all compensation,
expense and liabilities incurred, and all advances made, by the Trustee and the
costs and expenses of collection;

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

 
                                     -79-

          Third:  to the Issuers or to such party as a court of competent
jurisdiction shall direct.

          The Trustee may fix a record date and payment date for any payment to
Holders of Notes 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 a Trustee, a court in its discretion may require the filing by any party
litigant in the suit of an undertaking to pay the costs of the suit, and the
court in its discretion may assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in the suit, having due regard to
the merits and good faith of the claims or defenses made by the party litigant.
This Section does not apply to a suit by the Trustee, a suit by a Holder of a
Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in
principal amount of the then outstanding Notes.


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

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

             (i)  the duties of the Trustee shall be determined solely by the
     express provisions of this Indenture and the Trustee need perform only
     those duties that are specifically set forth in this Indenture and no
     others, and no implied covenants or obligations shall be read into this
     Indenture against the Trustee; and

            (ii)  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,
     the Trustee shall examine the certificates 

 
                                     -80-

     and opinions to determine whether or not they conform to the requirements
     of this Indenture.

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

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

            (ii)  the Trustee shall not be liable for any error of judgment made

     it takes or omits to take in good faith in accordance with a direction
     received by it pursuant to Section 6.05 hereof.

          (d)     Whether or not therein expressly so provided, every provision
of this Indenture that in any way relates to the Trustee is subject to
paragraphs (a), (b), and (c) of this Section.

          (e)     No provision of this Indenture shall require the Trustee to
expend or risk its own funds or incur any liability. The Trustee shall be under

the request of any Holders, unless such Holder shall have offered to the Trustee
security and indemnity satisfactory to it against any loss, liability or
expense.

received by it except as the Trustee may agree in writing with the Issuers.

                          ----------------- 

          (a)     The Trustee may conclusively rely upon, 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
require an Officers' Certificate or an Opinion of Counsel or both. The Trustee
shall not be liable for any action it takes or omits to take in good faith in

that might be incurred by it in compliance with such request or direction.

          (g)     The Trustee shall not be required to give any bond or surety
in respect of the performance of its powers and duties hereunder.

          (h)     Delivery of reports, information and documents to the Trustee
under Section 4.03 is for informational purposes only and the Trustee's receipt
of the foregoing shall not constitute constructive notice of any information
contained therein or determinable from information contained therein, including
the Company's compliance with any of their covenants hereunder (as to which the
Trustee is entitled to rely exclusively on Officers' Certificates).

          (i)     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 Indebtedness or Guarantor Senior Indebtedness or any representative
thereof.

          SECTION 7.03.   Individual Rights of Trustee.
                          ---------------------------- 

          The Trustee in its individual or any other capacity may become the

Affiliate of the Issuers 

 
                                     -82-

with the same rights it would have if it were not Trustee. However, in the event
that the Trustee acquires any conflicting interest it must eliminate such
conflict within 90 days, apply to the SEC for permission to continue as trustee
or resign. Any Agent may do the same with like rights and duties. The Trustee is
also subject to Sections 7.10 and 7.11 hereof.

          SECTION 7.04.   Trustee's Disclaimer.
                          -------------------- 

          The Trustee shall not be responsible for and makes no representation
as to the validity or adequacy of this Indenture or the Notes, it shall not be
accountable for the Issuers' use of the proceeds from the Notes or any money
paid to the Issuers or upon the Issuers' direction under any provision of this
Indenture, it shall not be responsible for the use or application of any money
received by any Paying Agent other than the Trustee, and it shall not be
responsible for any statement or recital herein or any statement in the Notes or
any other document in connection with the sale of the Notes or pursuant to this
Indenture other than its certificate of authentication.

                          ------------------ 

          If a Default or Event of Default occurs and is continuing and if it is
known to the Trustee, the Trustee shall mail to Holders of Notes a notice of the
Default or Event of Default within 90 days after it occurs.  Except in the case
of a Default or Event of Default in payment of principal of, premium, if any, or
interest on any Note, the Trustee may withhold the notice if and so long as a
committee of its Responsible Officers in good faith determines that withholding
the notice is in the interests of the Holders of the Notes.

          SECTION 7.06.   Reports by Trustee to Holders of the Notes.
                          ------------------------------------------ 

          Within 60 days after each May 15 beginning with the May 15 following
the date of this Indenture, and for so long as Notes remain outstanding, the
Trustee shall mail to the Holders of the Notes a brief report dated as of such
reporting date that complies with TIA (S) 313(a) (but if no event described in
TIA (S) 313(a) has occurred within the twelve months preceding the reporting
date, no report need be transmitted).  The Trustee also shall comply with TIA
(S) 313(b)(2).  The Trustee shall also transmit by mail all reports as required
by TIA (S) 313(c).

          A copy of each report at the time of its mailing to the Holders of
Notes shall be mailed to the Issuers and filed with the SEC and each stock
exchange on which the Notes are listed in accordance with TIA (S) 313(d).  The
Issuers shall promptly notify the Trustee when the Notes are listed on any stock
exchange.

 
                                     -83-

          SECTION 7.07.  Compensation and Indemnity.
                         -------------------------- 

          The Issuers shall pay to the Trustee from time to time reasonable
compensation for its acceptance of this Indenture and services hereunder as the
Issuers and the Trustee shall agree. The Trustee's compensation shall not be
limited by any law on compensation of a trustee of an express trust. The Issuers
shall reimburse the Trustee promptly upon request for all reasonable
disbursements, advances and expenses incurred or made by it in addition to the
compensation for its services. Such expenses shall include the reasonable
compensation, disbursements and expenses of the Trustee's agents and counsel.

          The Issuers and the Guarantors shall indemnify the Trustee and its
officers, directors, shareholders, agents and employees (each, an "Indeminified
Party") and hold the same harmless against any and all losses, liabilities or
expenses incurred by it arising out of or in connection with the acceptance or
administration of its duties and the exercise of its rights and powers under
this Indenture or the Notes, including the costs and expenses of enforcing this
Indenture against the Issuers (including this Section 7.07) and defending itself
against any claim (whether asserted by the Issuers or any Holder or any other
person) or liability in connection with the exercise or performance of any of
its powers or duties hereunder, except to the extent any such loss, liability or
expense may be attributable to its negligence or bad faith. The Trustee and its
officers, directors, shareholders, agents and employees, in its capacity as
Paying Agent, Registrar, Custodian, Exchange Agent, and agent for service of
notices and demands shall have the full benefit of the foregoing indemnity. The
Indemnified Party shall notify the Issuers promptly of any claim for which it
may seek indemnity. Failure by the Indemnified Party to so notify the Issuers
shall not relieve the Issuers of their obligations hereunder. The Issuers shall
defend the claim and the Trustee shall cooperate in the defense. The Indemnified
Party may have separate counsel reasonably satisfactory to the Indemnified Party
and the Issuers shall pay the reasonable fees and expenses of such counsel. The
Issuers need not pay for any settlement made without their consent, which
consent shall not be unreasonably withheld. The Trustee's right to receive
payment of any amounts under this Indenture shall not be subordinate to any
other Indebtedness of the Issuers.

          The obligations of the Issuers and the Guarantors under this Section
7.07 shall survive the satisfaction and discharge of this Indenture.

          To secure the Issuers' payment obligations in this Section, the
Trustee shall have a Lien prior to the Notes on all money or property held or
collected by the Trustee, except that held in trust to pay principal and
interest on particular Notes. Such Lien shall survive the satisfaction and
discharge of this Indenture.

 
                                     -84-

          When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 6.01(h) or (i) hereof occurs, the expenses and the
compensation for the services (including the fees and expenses of its agents and
counsel) are intended to constitute expenses of administration under any
Bankruptcy Law.

          The Trustee shall comply with the provisions of TIA (S) 313(b)(2) to
the extent applicable.

          SECTION 7.08.  Replacement of Trustee.
                         ----------------------

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

          The Trustee may resign in writing at any time and be discharged from
the trust hereby created by so notifying the Issuers. The Holders of Notes of a
majority in principal amount of the then outstanding Notes may remove the
Trustee by so notifying the Trustee and the Issuers in writing. The Issuers may
remove the Trustee if:

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

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

          (c)  a custodian or public officer takes charge of the Trustee or its
     property; or

          (d)  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 Issuers shall promptly appoint a successor
Trustee. Within one year after the successor Trustee takes office, the Holders
of a majority in principal amount of the then outstanding Notes may appoint a
successor Trustee to replace the successor Trustee appointed by the Issuers.

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

          If the Trustee, after written request by any Holder who has been a
Holder for at least six months, fails to comply with Section 7.10, such Holder
may petition any court

 
                                     -85-

of competent jurisdiction for the removal of the Trustee and the appointment of
a successor Trustee.

          A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Issuers. Thereupon, the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee shall mail a notice of its
succession to Holders. The retiring Trustee shall promptly transfer all property
held by it as Trustee to the successor Trustee, provided all sums owing to the
Trustee hereunder have been paid and subject to the Lien provided for in Section
7.07 hereof. Notwithstanding replacement of the Trustee pursuant to this Section
7.08, the Issuers' obligations under Section 7.07 hereof shall continue for the
benefit of the retiring Trustee.

          SECTION 7.09.  Successor Trustee by Merger, etc.
                         -------------------------------- 

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

          SECTION 7.10.  Eligibility; Disqualification.
                         ----------------------------- 

          There shall at all times be a Trustee hereunder that is a corporation
organized and doing business under the laws of the United States of America or
of any state thereof that is authorized under such laws to exercise corporate
trustee power, that is subject to supervision or examination by federal or state
authorities and that has a combined capital and surplus of at least $100 million
as set forth in its most recent published annual report of condition.

          This Indenture shall always have a Trustee who satisfies the
requirements of TIA (S) 310(a)(1), (2) and (5). The Trustee is subject to TIA
(S) 310(b).

          SECTION 7.11.  Preferential Collection of Claims Against Issuers.
                         ------------------------------------------------- 

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

 
                                     -86-


                                 ARTICLE EIGHT

                   LEGAL DEFEASANCE AND COVENANT DEFEASANCE

          SECTION 8.01.  Option to Effect Legal Defeasance or Covenant 
                         Defeasance.
                         ---------------------------------------------

          The Issuers may, at the option of their respective Boards of Directors
evidenced by resolutions set forth in Officers' Certificates, at any time, elect
to have either Section 8.02 or 8.03 hereof be applied to all outstanding Notes
upon compliance with the conditions set forth below in this Article Eight.

          SECTION 8.02.  Legal Defeasance and Discharge.
                         ------------------------------ 

          Upon the Issuers' exercise under Section 8.01 hereof of the option
applicable to this Section 8.02, the Issuers shall, subject to the satisfaction
of the conditions set forth in Section 8.04 hereof, be deemed to have been
discharged from their 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 Issuers 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 8.05 hereof and the other Sections of this Indenture
referred to in (a) and (b) below, and to have satisfied all their other
obligations under such Notes and this Indenture (and the Trustee, on demand of
and at the expense of the Issuers, shall execute proper instruments
acknowledging the same), except for the following provisions which shall survive
until otherwise terminated or discharged hereunder: (i) the rights of Holders of
outstanding Notes to receive payments in respect of the principal of, premium,
if any, and interest and Liquidated Damages, if any, on such Notes when such
payments are due from the trust referred to below, (ii) the Issuers' obligations
with respect to the Notes concerning issuing temporary Notes, registration of
Notes, mutilated, destroyed, lost or stolen Notes and the maintenance of an
office or agency for payment and money for security payments held in trust,
(iii) the rights, powers, trusts, duties and immunities of the Trustee, and the
Issuers' obligations in connection therewith and (iv) the Legal Defeasance
provisions of this Indenture. Subject to compliance with this Article Eight, the
Issuers may exercise their option under this Section 8.02 notwithstanding the
prior exercise of its option under Section 8.03 hereof.

 
                                     -87-

          SECTION 8.03.  Covenant Defeasance.
                         ------------------- 

          Upon the Issuers' exercise under Section 8.01 hereof of the option
applicable to this Section 8.03, the Issuers shall, subject to the satisfaction
of the conditions set forth in Section 8.04 hereof, be released from their
obligations under the covenants contained in Sections 4.07, 4.08, 4.09, 4.10,
4.11, 4.12, 4.13, and Sections 4.15 through 4.19 hereof with respect to the
outstanding Notes on and after the date the conditions set forth in Section 8.04
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 accounting purposes). For this
purpose, Covenant Defeasance means that, with respect to the outstanding Notes,
the Issuers may omit to comply with and shall have no liability in respect of
any term, condition or limitation set forth in any such covenant, whether
directly or indirectly, by reason of any reference elsewhere herein to any such
covenant or by reason of any reference in any such covenant to any other
provision herein or in any other document and such omission to comply shall not
constitute a Default or an Event of Default under Section 6.01 hereof, but,
except as specified above, the remainder of this Indenture and such Notes shall
be unaffected thereby. In addition, upon the Issuers' exercise under Section
8.01 hereof of the option applicable to this Section 8.03 hereof, subject to the
satisfaction of the conditions set forth in Section 8.04 hereof, Sections
6.01(d) through 6.01(g) hereof shall not constitute Events of Default.

          SECTION 8.04.  Conditions to Legal or Covenant Defeasance.
                         ------------------------------------------ 

          The following shall be the conditions to the application of either
Section 8.02 or 8.03 hereof to the outstanding Notes:

             (i)    the Company must irrevocably deposit with the Trustee, in
     trust, for the benefit of the Holders of the Notes, cash in U.S. dollars,
     non-callable Government Securities, 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 and Liquidated Damages, if any, on the outstanding
     Notes on the stated maturity or on the applicable redemption date, as the
     case may be, and the Company must specify whether the Notes are being
     defeased to maturity or to a particular redemption date;

             (ii)   in the case of Legal Defeasance, 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 pub-

 
                                     -88-

     lished by, the Internal Revenue Service a ruling or (B) since the date of
     this Indenture, there has been a change in the applicable federal income
     tax law, in either case to the effect that, and based thereon such opinion
     of counsel shall confirm that, the Holders of the outstanding Notes will
     not recognize income, gain or loss for federal income tax purposes as a
     result of such Legal Defeasance and will be subject to federal income tax
     on the same amounts, in the same manner and at the same times as would have
     been the case if such Legal Defeasance had not occurred;

             (iii)  in the case of Covenant Defeasance, 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
     outstanding Notes will not recognize income, gain or loss for federal
     income tax purposes as a result of such Covenant Defeasance and will be
     subject to 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;

             (iv)   no Default or Event of Default shall have occurred and be
     continuing on the date of such deposit (other than a Default or Event of
     Default resulting from the borrowing of funds to be applied to such
     deposit) or insofar as Events of Default from bankruptcy or insolvency
     events are concerned, at any time in the period ending on the effective
     date of such defeasance;

             (v)    such Legal Defeasance or Covenant Defeasance will not result
     in a breach or violation of, or constitute a default under any material
     agreement or instrument (other than this Indenture) to which the Company or
     any of its Subsidiaries is a party or by which the Company or any of its
     Subsidiaries is bound;

             (vi)   the Company must have delivered to the Trustee, at or prior
     to the effective date of such defeasance, an opinion of counsel to the
     effect that at the effective date of such defeasance, the trust funds will
     not be subject to the effect of any applicable bankruptcy, insolvency,
     reorganization or similar laws affecting creditors' rights generally;

             (vii)  the Company must deliver to the Trustee an Officers'
     Certificate stating that the deposit was not made by the Company with the
     intent of preferring the Holders of Notes over the other creditors of the
     Company with the intent of defeating, hindering, delaying or defrauding
     creditors of the Company or others; and

             (viii) the Company must deliver to the Trustee an Officers'
     Certificate and an opinion of counsel, each stating that all conditions
     precedent provided for relating to the Legal Defeasance or the Covenant
     Defeasance have been complied with.

 
                                     -89-

          SECTION 8.05.  Deposited Money and Government Securities to be Held in
                         Trust; Other Miscellaneous Provisions.
                         -------------------------------------------------------

          Subject to Section 8.06 hereof, all money and non-callable Government
Securities (including the proceeds thereof) deposited with the Trustee (or other
qualifying trustee, collectively for purposes of this Section 8.05, the
"Trustee") pursuant to Section 8.04 hereof in respect of the outstanding Notes
shall be held in trust and applied by the Trustee, in accordance with the
provisions of such Notes and this Indenture, to the payment, either directly or
through any Paying Agent (including the Issuers acting as Paying Agent) as the
Trustee may determine, to the Holders of such Notes of all sums due and to
become due thereon in respect of principal, premium, if any, and interest, but
such money need not be segregated from other funds except to the extent required
by law.

          The Issuers shall pay and indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against the cash or non-callable
Government Securities deposited pursuant to Section 8.04 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 notwithstanding, the
Trustee shall deliver or pay to the Issuers from time to time upon the request
of the Issuers any money or non-callable Government Securities held by it as
provided in Section 8.04 hereof which, in the opinion of a nationally recognized
firm of independent public accountants expressed in a written certification
thereof delivered to the Trustee (which may be the opinion delivered under
Section 8.04(a) hereof), 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 8.06.  Repayment to Issuers.
                         -------------------- 

          Any money deposited with the Trustee or any Paying Agent, or then held
by the Issuers, in trust for the payment of the principal of, premium, if any,
or interest on any Note and remaining unclaimed for two years after such
principal, and premium, if any, or interest has become due and payable shall be
paid to the Issuers on their request or (if then held by the Issuers) shall be
discharged from such trust; and the Holder of such Note shall thereafter look
only to the Issuers for payment thereof, and all liability of the Trustee or
such Paying Agent with respect to such trust money, and all liability of the
Issuers as trustee thereof, shall thereupon cease; provided, however, that the
Trustee or such Paying Agent, before being required to make any such repayment,
may at the expense of the Issuers cause to be published once, in the New York
Times and The Wall Street Journal (national edition), notice that such money
remains unclaimed and that, after a date specified

 
                                     -90-

therein, which shall not be less than 30 days from the date of such notification
or publication, any unclaimed balance of such money then remaining will be
repaid to the Issuers.

          SECTION 8.07.  Reinstatement.
                         ------------- 

          If the Trustee or Paying Agent is unable to apply any United States
dollars or non-callable Government Securities in accordance with Section 8.02 or
8.03 hereof, as the case may be, by reason of any order or judgment of any court
or governmental authority enjoining, restraining or otherwise prohibiting such
application, then the Issuers' obligations under this Indenture and the Notes
shall be revived and reinstated as though no deposit had occurred pursuant to
Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is
permitted to apply all such money in accordance with Section 8.02 or 8.03
hereof, as the case may be; provided, however, that, if the Issuers make any
payment of principal of, premium, if any, or interest on any Note following the
reinstatement of its obligations, the Issuers shall be subrogated to the rights
of the Holders of such Notes to receive such payment from the money held by the
Trustee or Paying Agent.

                                 ARTICLE NINE

                       AMENDMENT, SUPPLEMENT AND WAIVER

          SECTION 9.01.  Without Consent of Holders of Notes.
                         ----------------------------------- 

          Notwithstanding Section 9.02 of this Indenture, the Issuers, the
Guarantors and the Trustee may amend or supplement this Indenture, the
Guarantees with respect to the Notes or the Notes without the consent of any
Holder of a Note:

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

          (b)  to provide for uncertificated Notes in addition to or in place of
     certificated Notes or to alter the provisions of Article 2 hereof
     (including the related definitions) in a manner that does not materially
     adversely affect any Holder;

          (c)  to provide for the assumption of an Issuer's or a Guarantor's
     obligations to the Holders of the Notes by a successor to an Issuer or a
     Guarantor pursuant to Article 5 or Article 10 hereof;

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

 
                                     -91-

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

          (f)  to allow any Guarantor to execute a supplemental indenture and/or
     a Guarantee with respect to the Notes.

          Upon the request of the Issuers accompanied by resolutions of the
Boards of Directors of each of the Issuers authorizing the execution of any such
amended or supplemental Indenture, and upon receipt by the Trustee of the
documents described in Section 7.02 hereof, the Trustee shall join with the
Issuers and the Guarantors in the execution of any amended or supplemental
Indenture authorized or permitted by the terms of this Indenture and to make any
further appropriate agreements and stipulations that may be therein contained,
but the Trustee shall not be obligated to enter into such amended or
supplemental Indenture that affects its own rights, duties or immunities under
this Indenture or otherwise.

          SECTION 9.02.  With Consent of Holders of Notes.
                         -------------------------------- 

          Except as provided below in this Section 9.02, the Issuers and the
Trustee may amend or supplement this Indenture (including Section 3.09, 4.10 and
4.15 hereof), the Guarantees with respect to the Notes and the Notes with the
consent of the Holders of at least a majority in principal amount of the Notes
then outstanding voting as a single class (including consents obtained in
connection with a tender offer or exchange offer for, or purchase of, the
Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or
Event of Default (other than a Default or Event of Default in the payment of the
principal of, premium, if any, or interest on the Notes, except a payment
default resulting from an acceleration that has been rescinded) or compliance
with any provision of this Indenture, the Guarantees with respect to the Notes
or the Notes may be waived with the consent of the Holders of a majority in
principal amount of the then outstanding Notes voting as a single class
(including consents obtained in connection with a tender offer or exchange offer
for, or purchase of, the Notes).

          Upon the request of the Issuers accompanied by resolutions of the
Boards of Directors of each of the Issuers authorizing the execution of any such
amended or supplemental Indenture, and upon the filing with the Trustee of
evidence satisfactory to the Trustee of the consent of the Holders of Notes as
aforesaid, and upon receipt by the Trustee of the documents described in Section
7.02 hereof, the Trustee shall join with the Issuers in the execution of such
amended or supplemental Indenture unless such amended or supplemental Indenture
directly affects the Trustee's own rights, duties or immunities under this
Indenture or otherwise, in which case the Trustee may in its discretion, but
shall not be obligated to, enter into such amended or supplemental Indenture.

 
                                     -92-

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

          After an amendment, supplement or waiver under this Section becomes
effective, the Issuers shall mail to the Holders of Notes affected thereby a
notice briefly describing the amendment, supplement or waiver. Any failure of
the Issuers to mail such notice, or any defect therein, shall not, however, in
any way impair or affect the validity of any such amended or supplemental
Indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a
majority in aggregate principal amount of the Notes then outstanding voting as a
single class may waive compliance in a particular instance by the Issuers with
any provision of this Indenture or the Notes. However, without the consent of
each Holder affected, an amendment or waiver under this Section 9.02 may not
(with respect to any Notes held by a non-consenting Holder):

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

          (b)  reduce the principal of or change the fixed maturity of any Note
     or alter or waive any of the provisions with respect to the redemption of

          SECTION 9.03.  Compliance with Trust Indenture Act.
                         ----------------------------------- 

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

          SECTION 9.04.  Revocation and Effect of Consents.
                         --------------------------------- 

          Until an amendment, supplement or waiver becomes effective, a consent
to it by a Holder of a Note is a continuing consent by the Holder of a Note 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. However, any such Holder of a Note or subsequent Holder of a
Note may revoke the consent as to its Note if the Trustee receives written
notice of revocation before the date the waiver, supplement or amendment becomes
effective. An amendment, supplement or waiver becomes effective in accordance
with its terms and thereafter binds every Holder.

          SECTION 9.05.  Notation on or Exchange of Notes.
                         -------------------------------- 

          The Trustee may place an appropriate notation about an amendment,
supplement or waiver on any Note thereafter authenticated. The Issuers in
exchange for all Notes may issue and the Trustee shall, upon receipt of an
Authentication Order, authenticate new Notes that reflect the amendment,
supplement or waiver.

          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 9.06.  Trustee to Sign Amendments, etc.
                         ------------------------------- 

          The Trustee shall sign any amended or supplemental Indenture
authorized pursuant to this Article Nine if the amendment or supplement does not
adversely affect the rights, duties, liabilities or immunities of the Trustee.
The Issuers may not sign an amendment or supplemental Indenture until the Boards
of Directors of each of the Issuers approve it. In executing any amended or
supplemental indenture, the Trustee shall be entitled to receive and (subject to
Section 7.01 hereof) shall be fully protected in relying upon, in addition to
the documents required by Section 11.04 hereof, an Officer's Certificate and an
Opinion of Counsel stating that the execution of such amended or supplemental
indenture is authorized or permitted by this Indenture.

 
                                     -94-


                                  ARTICLE TEN

                                  GUARANTEES

          SECTION 10.01.  Guarantee.
                          --------- 

          Subject to this Article 10, each of the Guarantors hereby, jointly and
severally, unconditionally guarantees to each Holder of a Note authenticated and
delivered by the Trustee and to the Trustee and its successors and assigns,
irrespective of the validity and enforceability of this Indenture, the Notes or
the obligations of the Issuers hereunder or thereunder, that: (a) the principal
of and interest on the Notes will be promptly paid in full when due, whether at
maturity, by acceleration, redemption or otherwise, and interest on the overdue
principal of and interest on the Notes, if any, if lawful, and all other
obligations of the Issuers to the Holders or the Trustee hereunder or thereunder
will be promptly paid in full or performed, all in accordance with the terms
hereof and thereof; and (b) in case of any extension of time of payment or
renewal of any Notes or any of such other obligations, that same will be
promptly paid in full when due or performed in accordance with the terms of the
extension or renewal, whether at stated maturity, by acceleration or otherwise.
Failing payment when due of any amount so guaranteed or any performance so
guaranteed for whatever reason, the Guarantors shall be jointly and severally
obligated to pay the same immediately. Each Guarantor agrees that this is a
guarantee of payment and not a guarantee of collection.

          The Guarantors hereby agree that their obligations hereunder shall be
unconditional, irrespective of the validity, regularity or enforceability of the
Notes or this Indenture, the absence of any action to enforce the same, any
waiver or consent by any Holder of the Notes with respect to any provisions
hereof or thereof, the recovery of any judgment against the Issuers, any action
to enforce the same or any other circumstance which might otherwise constitute a
legal or equitable discharge or defense of a guarantor. Each Guarantor hereby
waives diligence, presentment, demand of payment, filing of claims with a court
in the event of insolvency or bankruptcy of either Issuer, any right to require
a proceeding first against either Issuer, protest, notice and all demands
whatsoever and covenant that this Guarantee shall not be discharged except by
complete performance of the obligations contained in the Notes and this
Indenture.

          If any Holder or the Trustee is required by any court or otherwise to
return to the Issuers, the Guarantors or any custodian, trustee, liquidator or
other similar official acting in relation to either the Issuers or the
Guarantors, any amount paid by either to the Trustee or such Holder, this
Guarantee, to the extent theretofore discharged, shall be reinstated in full
force and effect.

 
                                     -95-

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

          SECTION 10.02.  Limitation on Guarantor Liability.
                          --------------------------------- 

          Each Guarantor, and by its acceptance of Notes, each Holder, hereby
confirms that it is the intention of all such parties that the Guarantee of the
Notes of such Guarantor not constitute a fraudulent transfer or conveyance for
purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform
Fraudulent Transfer Act or any similar federal or state law to the extent
applicable to any Guarantee. To effectuate the foregoing intention, the Trustee,
the Holders and the Guarantors hereby irrevocably agree that the obligations of
each Guarantor under its Guarantee of the Notes and this Article 10 shall be
limited to the maximum amount as will, after giving effect to such maximum
amount and all other contingent and fixed liabilities of such Guarantor that are
relevant under such laws, and after giving effect to any collections from,
rights to receive contribution from or payments made by or on behalf of any
other Guarantor in respect of the obligations of such other Guarantor under this
Article 10, result in the obligations of such Guarantor under its Guarantee of
the Notes not constituting a fraudulent transfer or conveyance under applicable
law.

          SECTION 10.03.  Execution and Delivery of Guarantee.
                          ----------------------------------- 

          To evidence its Guarantee set forth in Section 10.01, each Guarantor
hereby agrees that a notation of such Guarantee substantially in the form
included in Exhibit E shall be endorsed by an Officer of such Guarantor on each
Note authenticated and delivered by the Trustee and that this Indenture shall be
executed on behalf of such Guarantor by its President or one of its Vice
Presidents.

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

 
                                     -96-

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

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

          In the event that the Issuers create or acquire any new Subsidiaries
subsequent to the date of this Indenture, if required by Section 4.19 hereof,
the Issuers shall cause such Subsidiaries to execute supplemental indentures to
this Indenture and Guarantees in accordance with Section 4.19 hereof and this
Article 10, to the extent applicable. No Subsidiary of an Issuer is required to
endorse a Subsidiary Guarantee unless such Subsidiary is required to, and does,
simultaneously execute a Guarantee of the Senior Credit Facilities.

          SECTION 10.04.  Subsidiary Guarantors May Consolidate, Etc., on
                          Certain Terms.
                          -----------------------------------------------

          Except as otherwise provided in Section 10.05, no Subsidiary Guarantor
may consolidate with or merge with or into (whether or not such Subsidiary
Guarantor is the surviving Person) another corporation, Person or entity whether
or not affiliated with such Subsidiary Guarantor unless:

          (a)  subject to Section 10.05 hereof, the Person formed by or
     surviving any such consolidation or merger (if other than such Subsidiary
     Guarantor) assumes all the obligations of such Subsidiary Guarantor
     pursuant to a supplemental indenture in form and substance reasonably
     satisfactory to the Trustee, under the Notes, this Indenture and the
     Registration Rights Agreement;

          (b)  immediately after giving effect to such transaction, no Default
     or Event of Default exists; and

          (c)  the Company would be permitted by virtue of the Company's pro
     forma Fixed Charge Coverage Ratio, immediately after giving effect to such
     transaction, to incur at least $1.00 of additional Indebtedness pursuant to
     the Fixed Charge Coverage Ratio test set forth in the first paragraph of
     Section 4.09 hereof.

          In the event of any such consolidation, merger, sale or conveyance and
upon the assumption by the successor Person, by supplemental indenture, executed
and delivered to the Trustee and satisfactory in form to the Trustee, of the
Subsidiary Guarantee endorsed

 
                                     -97-

upon the Notes and the due and punctual performance of all of the covenants and
conditions of this Indenture to be performed by the Subsidiary Guarantor, such
successor Person shall succeed to and be substituted for the Subsidiary
Guarantor with the same effect as if it had been named herein as a Subsidiary
Guarantor. Such successor Person thereupon may cause to be signed any or all of
the Subsidiary Guarantees to be endorsed upon all of the Notes issuable
hereunder which theretofore shall not have been signed by the Issuers and
delivered to the Trustee. All the Subsidiary Guarantees so issued shall in all
respects have the same legal rank and benefit under this Indenture as the
Subsidiary Guarantees theretofore and thereafter issued in accordance with the
terms of this Indenture as though all of such Subsidiary Guarantees had been
issued at the date of the execution hereof.

          Except as set forth in Articles 4 and 5 hereof, and notwithstanding
clause (a) above, nothing contained in this Indenture or in any of the Notes
shall prevent any consolidation or merger of a Subsidiary Guarantor with or into
the Issuers or another Subsidiary Guarantor, or shall prevent any sale or
conveyance of the property of a Subsidiary Guarantor as an entirety or
substantially as an entirety to the Issuers or another Subsidiary Guarantor.

          SECTION 10.05.  Releases Following Sale of Assets.
                          --------------------------------- 

          In the event of a sale or other disposition of all of the assets of
any Subsidiary Guarantor, by way of merger, consolidation or otherwise, a sale
or other disposition of all of the capital stock of any Subsidiary Guarantor or
the designation of a Subsidiary Guarantor as an Unrestricted Subsidiary in
accordance with the terms of this Indenture, then such Subsidiary Guarantor (in
the event of a sale or other disposition, by way of merger, consolidation or
otherwise, of all of the capital stock of such Subsidiary Guarantor) or the
corporation acquiring the property (in the event of a sale or other disposition
of all or substantially all of the assets of such Subsidiary Guarantor) will be
released and relieved of any obligations under its Subsidiary Guarantee;
provided that the Net Proceeds of such sale or other disposition are applied in
accordance with the applicable provisions of this Indenture, including without
limitation Section 4.10 hereof. Upon delivery by each Issuer to the Trustee of
an Officers' Certificate and an Opinion of Counsel to the effect that such sale
or other disposition was made by the Issuers in accordance with the applicable
provisions of this Indenture, including without limitation Section 4.10 hereof,
the Trustee shall execute any documents reasonably required in order to evidence
the release of any Subsidiary Guarantor from its obligations under its
Subsidiary Guarantee.

          Any Subsidiary Guarantor not released from its obligations under its
Subsidiary Guarantee shall remain liable for the full amount of principal of and
interest on the Notes and for the other obligations of any Subsidiary Guarantor
under this Indenture as provided in this Article 10.

WITH THE PRIOR WRITTEN CONSENT OF AEI RESOURCES, INC. AND AEI HOLDING COMPANY,
INC.

          Capitalized terms used herein shall have the meanings assigned to them
in the Indenture referred to below unless otherwise indicated.

          1.   Interest.  AEI Resources, Inc., a Delaware corporation (the
"Company") and AEI Holding Company, Inc., a Delaware corporation ("Old AEI" and,
together with the Company, the "Issuers") promise to pay interest on the
principal amount of this Note at 10 1/2% per annum from December 15, 1998 until
maturity and shall pay the Liquidated Damages payable pursuant to Section 5 of
the Registration Rights Agreement referred to below.  The Issuers will pay
interest and Liquidated Damages semi-annually on December 15 and June 15 of each
year, or if any such day is not a Business Day, on the next succeeding Business
Day (each an "Interest Payment Date").  Interest on the Notes will accrue from
the most recent date to which interest has been paid or, if no interest has been
paid, from the date of issuance; provided that if there is no existing Default
in the payment of interest, and if this Note is authenticated between a record
date referred to on the face hereof and the next succeeding Interest Payment
Date, interest shall accrue from such next succeeding Interest Payment Date;
provided, further, that the first Interest Payment Date shall be December 15,
1998.  The Issuers shall pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue principal and premium, if any,
from time to time on demand at a rate that is 1% per annum in excess of the rate
then in effect; it shall pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue installments of interest and
Liquidated Damages (without regard to any applicable grace periods) from time to
time on demand at the same rate to the extent lawful.  Interest will be computed
on the basis of a 360-day year of twelve 30-day months.

          2.   Method of Payment.  The Issuers will pay interest on the Notes
(except defaulted interest) and Liquidated Damages to the Persons who are
registered Holders of Notes at the close of business on the December 1 or June 1
next preceding the Interest Payment Date, even if such Notes are canceled after
such record date and on or before such Interest Payment Date, except as provided
in Section 2.12 of the Indenture with respect to defaulted interest.  The Notes
will be payable as to principal, premium and Liquidated Damages, if any, and
interest at the office or agency of the Issuers maintained for such purpose
within or without the City and State of New York, or, at the option of the
Issuers, payment of interest and Liquidated Damages may be made by check mailed
to the 

                                     A-1-4

 
Holders at their addresses set forth in the register of Holders, and
provided that payment by wire transfer of immediately available funds will be
required with respect to principal of and interest, premium and Liquidated
Damages on, all Global Notes and all other Notes the Holders of which shall have
provided wire transfer instructions to the Issuers or the Paying Agent.  Such
payment shall be in such coin or currency of the United States of America as at
the time of payment is legal tender for payment of public and private debts;
provided that Liquidated Damages may be paid through the issuance of additional
Notes having a value at the time of issuance equal to the amount of Liquidated
Damages so paid.

          3.   Paying Agent and Registrar.  Initially, IBJ Schroder Bank & Trust
Company, the Trustee under the Indenture, will act as Paying Agent and
Registrar.  The Issuers may change any Paying Agent or Registrar without notice
to any Holder.  Either Issuer or any of their Subsidiaries may act in any such
capacity.

          4.   Indenture .  The Issuers issued the Notes under an Indenture
dated as of December 14, 1998 ("Indenture") among the Issuers, the guarantors
named therein and the Trustee.  The terms of the Notes include those stated in
the Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939, as amended (15 U.S. Code (S)(S) 77aaa-77bbbb).  The Notes
are subject to all such terms, and Holders are referred to the Indenture and
such Act for a statement of such terms.  To the extent any provision of this
Note conflicts with the express provisions of the Indenture, the provisions of
the Indenture shall govern and be controlling.  The Notes are obligations of the
Issuers limited to $200.0 million in aggregate principal amount, plus amounts,
if any, issued to pay Liquidated Damages on outstanding Notes as set forth in
Paragraph 2 hereof.

          5.   Optional Redemption.

          (a)  The Notes will be subject to redemption at any time at the option
of the Company, in whole or in part, upon not less than 30 nor more than 60
days' notice, at the redemption prices (expressed as percentages of principal
amount) set forth below plus accrued and unpaid interest and Liquidated Damages
thereon to the applicable redemption date if redeemed during the twelve-month
period beginning on each December 15 of the years indicated below:

 
 
          YEAR                                    PERCENTAGE
          ----                                    ----------
                                                
          2002..........................          105.250%  
          2003..........................          103.500%  
          2004 and thereafter...........          101.750%   
 

          In addition, prior to December 15, 2002, the Notes will be redeemable
at a price equal to 100% of the principal amount thereof plus an applicable Make
Whole Premium, plus, to the extent not included in the Make Whole Premium,
accrued and unpaid interest and Liquidated Damages, if any, to the date of
redemption.

                                     A-1-5

 
          For purposes of the foregoing, the "Make Whole Premium" means, with
respect to a Note, an amount equal to the greater of (A) the redemption price of
such Note on December 15, 2002 and (B) the excess of, if any, (1) the present
value of the remaining interest, premium, if any, and principal payments due on
such Note as if such Note were redeemed on December 15, 2002, computed using a
discount rate equal to the Treasury Rate plus 50 basis points, over (2) the
outstanding principal amount of such Note.

          "Treasury Rate" means the yield to maturity at the time of computation
of United States Treasury securities with a constant maturity (as compiled by,
and published in, the most recent Federal Reserve Statistical Release H.15 (519)
which has become publicly available at least two business days prior to the date
fixed for redemption of the Notes (or, if such Statistical Release is no longer
published, any publicly available source of similar market data)) most nearly
equal to the then remaining Weighted Average Life to Maturity of the Notes;
provided, however, that if the Weighted Average Life to Maturity of the Notes is
not equal to the constant maturity of a United States Treasury security for
which a weekly average yield is given, the Treasury Rate shall be obtained by
linear interpolation (calculated to the nearest one-twelfth of a year) from the
weekly average yields of United States Treasury securities for which such yields
are given, except that if the Weighted Average Life to Maturity of the Notes is
less than one year, the weekly average yield on actually traded United States
Treasury securities adjusted to a constant maturity of one year shall be used.

          (b)  Notwithstanding the foregoing, at any time on or before December
15, 2000, the Company may on any one or more occasions redeem up to 35% of the
aggregate principal amount of Notes ever issued under this Indenture at a
redemption price equal to the principal amount thereof plus a premium equal 110
1/2% of the principal amount thereof, plus accrued and unpaid interest and
Liquidated Damages thereon, if any, to the redemption date, with the net cash
proceeds of an initial public offering of common stock of the Company or
Holdings (to the extent that the net proceeds therefrom are contributed to the
Company as common equity capital); provided that at least 65% of the aggregate
principal amount of Notes issued on the date of this Indenture remains
outstanding immediately after the occurrence of such redemption (excluding Notes
held by Holdings or the Company and their Subsidiaries) and provided, further,
that such redemption shall occur within 45 days of the date of the closing of
such initial public offering.

          6.   Mandatory Redemption.

          Except as set forth in paragraph 7 below, the Issuers shall not be
required to make mandatory redemption payments with respect to the Notes.

                                     A-1-6

 
          7.   Repurchase at Option of Holder.

          (a)  If there is a Change of Control, each Holder of the Notes will
have the right to require the Issuers to make an offer (a "Change of Control
Offer") to repurchase all or any part (equal to $1,000 or an integral multiple
thereof) of each Holder's Notes at a purchase price equal to 101% of the
aggregate principal amount thereof plus accrued and unpaid interest and
Liquidated Damages thereon, if any, to the date of purchase (the "Change of
Control Payment").  Within 10 days following any Change of Control, the Issuers
shall mail a notice to each Holder setting forth the procedures governing the
Change of Control Offer as required by the Indenture.

          (b)  If the Issuers or a Subsidiary consummates any Asset Sales,
within five days of each date on which the aggregate amount of Excess Proceeds
exceeds $2.0 million, the Issuers shall commence an offer to all Holders of
Notes (as "Asset Sale Offer") pursuant to Section 3.09 of the Indenture to
purchase the maximum principal amount of Notes that may be purchased out of the
Excess Proceeds at an offer price in cash in an amount equal to 100% of the
principal amount thereof plus accrued and unpaid interest and Liquidated Damages
thereon, if any, to the date fixed for the closing of such offer in accordance
with the procedures set forth in the Indenture. To the extent that the aggregate
amount of Notes tendered pursuant to an Asset Sale Offer is less than the Excess
Proceeds, the Issuers (or such Subsidiary) may use such deficiency for general
corporate purposes. If the aggregate principal amount of Notes surrendered by
Holders thereof exceeds the amount of Excess Proceeds, the Trustee shall select
the Notes to be purchased on a pro rata basis. Holders of Notes that are the
subject of an offer to purchase will receive an Asset Sale Offer from the
Issuers prior to any related purchase date and may elect to have such Notes
purchased by completing the form entitled "Option of Holder to Elect Purchase"
on the reverse of the Notes.

          8.   Notice of Redemption.  Notice of redemption will be mailed at
least 30 days but not more than 60 days before the redemption date to each
Holder whose Notes are to be redeemed at its registered address.  Notes in
denominations larger than $1,000 may be redeemed in part but only in whole
multiples of $1,000, unless all of the Notes held by a Holder are to be
redeemed.  On and after the redemption date interest ceases to accrue on Notes
or portions thereof called for redemption.

          9.   Denominations, Transfer, Exchange.  The Notes are in registered
form in denominations of $1,000 and integral multiples of $1,000.  The transfer
of Notes may be registered and Notes may be exchanged as provided in the
Indenture.  The Registrar and the Trustee may require a Holder, among other
things, to furnish appropriate endorsements and transfer documents and the
Issuers may require a Holder to pay any taxes and fees required by law or
permitted by the Indenture.  The Issuers need not exchange or register the
transfer of any Note or portion of a Note selected for redemption, except for
the unredeemed portion of any Note being redeemed in part.  Also, the Issuers
need not ex-

                                     A-1-7

 
change or register the transfer of any Notes for a period of 15 days before a
selection of Notes to be redeemed or during the period between a record date and
the corresponding Interest Payment Date.

          10.  Persons Deemed Owners.  The registered Holder of a Note may be
treated as its owner for all purposes.

          11.  Amendment, Supplement and Waiver.  Subject to certain exceptions,
the Indenture, the Guarantees or the Notes may be amended or supplemented with
the consent of the Holders of at least a majority in principal amount of the
then outstanding Notes voting as a single class and any existing default or
compliance with any provision of the Indenture, the Guarantees or the Notes may
be waived with the consent of the Holders of a majority in principal amount of
the then outstanding Notes voting as a single class.  Without the consent of any
Holder of a Note, the Indenture, the Guarantees or the Notes may be amended or
supplemented to cure any ambiguity, defect or inconsistency, to provide for
uncertificated Notes in addition to or in place of certificated Notes, to
provide for the assumption of the Issuers' or Guarantor's obligations to Holders
of the Notes in case of a merger or consolidation, to make any change that would
provide any additional rights or benefits to the Holders of the Notes or that
does not adversely affect the legal rights under the Indenture of any such
Holder, to comply with the requirements of the Commission in order to effect or
maintain the qualification of the Indenture under the Trust Indenture Act or to
allow any Guarantor to execute a supplemental indenture to the Indenture and/or
a Guarantee with respect to the Notes.

          12.  Defaults and Remedies.  Each of the following constitutes an
Event of Default: (a) default for 30 days in the payment when due of interest
on, or Liquidated Damages, if any, with respect to, the Notes; (b) default in
payment when due of the principal of or premium, if any, on the Notes; (c)
failure by the Company or any of its Subsidiaries to make the offer required or
to purchase any of the Notes as required under the provisions described under
Section 4.10 or Section 4.15; (d) failure by the Company or any of its
Subsidiaries for 30 days after notice to comply with the provisions of Section
4.07 or Section 4.09, or failure by the Company or any of its Subsidiaries for
60 days after notice to comply with any of its other agreements in the Indenture
or the Notes; (e) default under any mortgage, indenture or instrument under
which there may be issued or by which there may be secured or evidenced any
Indebtedness for money borrowed by the Company or any of its Restricted
Subsidiaries (or the payment of which is guaranteed by the Company or any of its
Restricted Subsidiaries) whether such Indebtedness or guarantee now exists, or
is created after the date of the Indenture, which default (a) is caused by a
failure to pay principal of or premium, if any, or interest on such Indebtedness
prior to the expiration of the grace period provided in such Indebtedness on the
date of such default (a "Payment Default") or (b) results in the acceleration of
such Indebtedness prior to its express maturity and, in each case, the principal
amount of any such Indebtedness, together with the principal amount of any other
such Indebtedness under which there has been a Payment Default 

                                     A-1-8

 
or the maturity of which has been so accelerated, aggregates $25.0 million or
more; (f) failure by the Company or any of its Restricted Subsidiaries or any
group of Restricted Subsidiaries that, taken as a whole, would be a Significant
Subsidiary to pay final judgments aggregating in excess of $25.0 million, which
judgments are not paid, discharged or stayed for a period of 60 days; (g) except
as permitted by the Indenture, any Guarantee of the Notes shall be held in any
judicial proceeding to be unenforceable or invalid or shall cease for any reason
to be in full force and effect or any Guarantor, or any Person acting on behalf
of any Guarantor, shall deny or disaffirm its obligations under its Guarantee of
the Notes; and (h) certain events of bankruptcy or insolvency with respect to
the Company, any of its Significant Subsidiaries that are Restricted
Subsidiaries or any group of Restricted Subsidiaries that, taken as a whole,
would be a Significant Subsidiary. If any Event of Default occurs and is
continuing, the Trustee or the Holders of at least 25% in principal amount of
the then outstanding Notes may declare all the Notes to be due and payable.
Notwithstanding the foregoing, in the case of an Event of Default arising from
certain events of bankruptcy or insolvency, all outstanding Notes will become
due and payable without further action or notice. Holders may not enforce the
Indenture or the Notes except as provided in the Indenture. Subject to certain
limitations, Holders of a majority in principal amount of the then outstanding
Notes may direct the Trustee in its exercise of any trust or power. The Trustee
may withhold from Holders of the Notes notice of any continuing Default or Event
of Default (except a Default or Event of Default relating to the payment of
principal or interest) if it determines that withholding notice is in their
interest. The Holders of a majority in aggregate principal amount of the Notes
then outstanding by notice to the Trustee may on behalf of the Holders of all of
the Notes waive any existing Default or Event of Default and its consequences
under the Indenture except a continuing Default or Event of Default in the
payment of interest on, or the principal of, the Notes. Each Issuer is required
to deliver to the Trustee annually a statement regarding compliance with the
Indenture, and each Issuer is required upon becoming aware of any Default or
Event of Default, to deliver to the Trustee a statement specifying such Default
or Event of Default.

          13.  Trustee Dealings with Issuers.  The Trustee, in its individual or
any other capacity, may make loans to, accept deposits from, and perform
services for the Issuers or their Affiliates, and may otherwise deal with the
Issuers or their Affiliates, as if it were not the Trustee.

          14.  No Recourse Against Others.  A director, officer, employee,
incorporator or stockholder, of either Issuer, as such, shall not have any
liability for any obligations of the Issuers under the Notes or the Indenture or
for any claim based on, in respect of, or by reason of, such obligations or
their creation.  Each Holder 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.

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

                                     A-1-9

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

          17.  Additional Rights of Holders of Restricted Global Notes and
Restricted Definitive Notes.  In addition to the rights provided to Holders of
Notes under the Indenture, Holders of Restricted Global Notes and Restricted
Definitive Notes shall have all the rights set forth in the Registration Rights
Agreement dated as of December 14, 1998, among the Issuers, the Guarantors and
the party named on the signature pages thereof (the "Registration Rights
Agreement").

          18.  CUSIP Numbers.  Pursuant to a recommendation promulgated by the
Committee on Uniform Security Identification Procedures, the Issuers have caused
CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP numbers
in notices of redemption as a convenience to Holders.  No representation is made
as to the accuracy of such numbers either as printed on the Notes or as
contained in any notice of redemption and reliance may be placed only on the
other identification numbers placed thereon.

          The Issuers will furnish to any Holder upon written request and
without charge a copy of the Indenture and/or the Registration Rights Agreement.
Requests may be made to:

          Capitalized terms used herein shall have the meanings assigned to them
in the Indenture referred to below unless otherwise indicated.

          1.   Interest.  AEI Resources, Inc., a Delaware corporation (the
"Company") and AEI Holding Company, Inc., a Delaware corporation ("Old AEI" and,
together with the Company, the "Issuers"), promise to pay interest on the
principal amount of this Note at 10 1/2% per annum from December 15, 1998 until
maturity and shall pay the Liquidated Damages payable pursuant to Section 5 of
the Registration Rights Agreement referred to below.  The Issuers will pay
interest and Liquidated Damages semi-annually on December 15 and June 15 of each
year, or if any such day is not a Business Day, on the next succeeding Business
Day (each an "Interest Payment Date").  Interest on the Notes will accrue from
the most recent date to which interest has been paid or, if no interest has been
paid, from the date of issuance; provided that if there is no existing Default
in the payment of interest, and if this Note is authenticated between a record
date referred to on the face hereof and the next succeeding Interest Payment
Date, interest shall accrue from such next succeeding Interest Payment Date;
provided, further, that the first Interest Payment Date shall be December 15,
1998.  The Issuers shall pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue principal and premium, if any,
from time to time on demand at a rate that is 1% per annum in excess of the rate
then in effect; it shall pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue installments of interest and
Liquidated Damages (without regard to any applicable grace periods) from time to
time on demand at the same 

                                     A-2-4

 
rate to the extent lawful. Interest will be computed on the basis of a 360-day
year of twelve 30-day months.

          Until this Regulation S Temporary Global Note is exchanged for one or
more Regulation S Permanent Global Notes, the Holder hereof shall not be
entitled to receive payments of interest hereon; until so exchanged in full,
this Regulation S Temporary Global Note shall in all other respects be entitled
to the same benefits as other Senior Subordinated Notes under the Indenture.

          2.   Method of Payment.  The Issuers will pay interest on the Notes
(except defaulted interest) and Liquidated Damages to the Persons who are
registered Holders of Notes at the close of business on the December 1 or June 1
next preceding the Interest Payment Date, even if such Notes are canceled after
such record date and on or before such Interest Payment Date, except as provided
in Section 2.12 of the Indenture with respect to defaulted interest.  The Notes
will be payable as to principal, premium and Liquidated Damages, if any, and
interest at the office or agency of the Issuers maintained for such purpose
within or without the City and State of New York, or, at the option of the
Issuers, payment of interest and Liquidated Damages may be made by check mailed
to the Holders at their addresses set forth in the register of Holders, and
provided that payment by wire transfer of immediately available funds will be
required with respect to principal of and interest, premium and Liquidated
Damages on, all Global Notes and all other Notes the Holders of which shall have
provided wire transfer instructions to the Issuers or the Paying Agent.  Such
payment shall be in such coin or currency of the United States of America as at
the time of payment is legal tender for payment of public and private debts;
provided that Liquidated Damages may be paid through the issuance of additional
Notes having a value at the time of issuance equal to the amount of Liquidated
Damages so paid.

          3.   Paying Agent and Registrar.  Initially, IBJ Schroder Bank & Trust
Company, the Trustee under the Indenture, will act as Paying Agent and
Registrar.  The Issuer may change any Paying Agent or Registrar without notice
to any Holder.  Either Issuer or any of their Subsidiaries may act in any such
capacity.

          4.   Indenture.  The Issuers issued the Notes under an Indenture
dated as of December 14, 1998 ("Indenture") among the Issuers, the guarantors
named therein and the Trustee.  The terms of the Notes include those stated in
the Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939, as amended (15 U.S. Code (S)(S) 77aaa-77bbbb).  The Notes
are subject to all such terms, and Holders are referred to the Indenture and
such Act for a statement of such terms.  To the extent any provision of this
Note conflicts with the express provisions of the Indenture, the provisions of
the Indenture shall govern and be controlling.  The Notes are obligations of the
Issuers limited to $200.0 million in aggregate principal amount, plus amounts,
if any, issued to pay Liquidated Damages on outstanding Notes as set forth in
Paragraph 2 hereof.

                                     A-2-5

 
          5.  Optional Redemption.

          (a) The Notes will be subject to redemption at any time at the option
of the Company, in whole or in part, upon not less than 30 nor more than 60
days' notice, at the redemption prices (expressed as percentages of principal
amount) set forth below plus accrued and unpaid interest and Liquidated Damages
thereon to the applicable redemption date if redeemed during the twelve-month
period beginning on each December 15 of the years indicated below:

          YEAR                           PERCENTAGE
          ----                           ----------
          2002........................    105.250%
          2003........................    103.500%
          2004 and thereafter.........    101.750%

          In addition, prior to December 15, 2002, the Notes will be redeemable
at a price equal to 100% of the principal amount thereof plus an applicable Make
Whole Premium, plus, to the extent not included in the Make Whole Premium,
accrued and unpaid interest and Liquidated Damages, if any, to the date of
redemption.

          For purposes of the foregoing, the "Make Whole Premium" means, with
respect to a Note, an amount equal to the greater of (A) the redemption price of
such Note on December 15, 2002 and (B) the excess of, if any, (1) the present
value of the remaining interest, premium, if any, and principal payments due on
such Note as if such Note were redeemed on December 15, 2002, computed using a
discount rate equal to the Treasury Rate plus 50 basis points, over (2) the
outstanding principal amount of such Note.

          "Treasury Rate" means the yield to maturity at the time of computation
of United States Treasury securities with a constant maturity (as compiled by,
and published in, the most recent Federal Reserve Statistical Release H.15 (519)
which has become publicly available at least two business days prior to the date
fixed for redemption of the Notes (or, if such Statistical Release is no longer
published, any publicly available source of similar market data)) most nearly
equal to the then remaining Weighted Average Life to Maturity of the Notes;
provided, however, that if the Weighted Average Life to Maturity of the Notes is
not equal to the constant maturity of a United States Treasury security for
which a weekly average yield is given, the Treasury Rate shall be obtained by
linear interpolation (calculated to the nearest one-twelfth of a year) from the
weekly average yields of United States Treasury securities for which such yields
are given, except that if the Weighted Average Life to Maturity of the Notes is
less than one year, the weekly average yield on actually traded United States
Treasury securities adjusted to a constant maturity of one year shall be used.

          (b) Notwithstanding the foregoing, at any time on or before December
15, 2000, the Company may on any one or more occasions redeem up to 35% of the
aggre-

                                     A-2-6

 
gate principal amount of Notes ever issued under this Indenture at a redemption
price equal to the principal amount thereof plus a premium equal 110 1/2% of the
principal amount thereof, plus accrued and unpaid interest and Liquidated
Damages thereon, if any, to the redemption date, with the net cash proceeds of
an initial public offering of common stock of the Company or Holdings (to the
extent that the net proceeds therefrom are contributed to the Company as common
equity capital); provided that at least 65% of the aggregate principal amount of
Notes issued on the date of this Indenture remains outstanding immediately after
the occurrence of such redemption (excluding Notes held by Holdings or the
Company and their Subsidiaries) and provided, further, that such redemption
shall occur within 45 days of the date of the closing of such initial public
offering.

          6.   Mandatory Redemption.

          Except as set forth in paragraph 7 below, the Issuers shall not be
required to make mandatory redemption payments with respect to the Notes.

          7.   Repurchase at Option of Holder.

          (a) If there is a Change of Control, each Holder of the Notes will
have the right to require the Issuers to make an offer (a "Change of Control
Offer") to repurchase all or any part (equal to $1,000 or an integral multiple
thereof) of each Holder's Notes at a purchase price equal to 101% of the
aggregate principal amount thereof plus accrued and unpaid interest and
Liquidated Damages thereon, if any, to the date of purchase (the "Change of
Control Payment").  Within 10 days following any Change of Control, the Issuers
shall mail a notice to each Holder setting forth the procedures governing the
Change of Control Offer as required by the Indenture.

          (b) If the Issuers or a Subsidiary consummates any Asset Sales, within
five days of each date on which the aggregate amount of Excess Proceeds exceeds
$2.0 million, the Issuers shall commence an offer to all Holders of Notes (as
"Asset Sale Offer") pursuant to Section 3.09 of the Indenture to purchase the
maximum principal amount of Notes that may be purchased out of the Excess
Proceeds at an offer price in cash in an amount equal to 100% of the principal
amount thereof plus accrued and unpaid interest and Liquidated Damages thereon,
if any, to the date fixed for the closing of such offer in accordance with the
procedures set forth in the Indenture.  To the extent that the aggregate amount
of Notes tendered pursuant to an Asset Sale Offer is less than the Excess
Proceeds, the Issuers (or such Subsidiary) may use such deficiency for general
corporate purposes.  If the aggregate principal amount of Notes surrendered by
Holders thereof exceeds the amount of Excess Proceeds, the Trustee shall select
the Notes to be purchased on a pro rata basis.  Holders of Notes that are the
subject of an offer to purchase will receive an Asset Sale Offer from the
Issuers prior to any related purchase date and may elect to have such Notes
purchased by completing the form entitled "Option of Holder to Elect Purchase"
on the reverse of the Notes.

                                     A-2-7

 
          8.   Notice of Redemption.  Notice of redemption will be mailed at
least 30 days but not more than 60 days before the redemption date to each
Holder whose Notes are to be redeemed at its registered address.  Notes in
denominations larger than $1,000 may be redeemed in part but only in whole
multiples of $1,000, unless all of the Notes held by a Holder are to be
redeemed.  On and after the redemption date interest ceases to accrue on Notes
or portions thereof called for redemption.

          9.   Denominations, Transfer, Exchange.  The Notes are in registered
form in denominations of $1,000 and integral multiples of $1,000.  The transfer
of Notes may be registered and Notes may be exchanged as provided in the
Indenture.  The Registrar and the Trustee may require a Holder, among other
things, to furnish appropriate endorsements and transfer documents and the
Issuers may require a Holder to pay any taxes and fees required by law or
permitted by the Indenture.  The Issuers need not exchange or register the
transfer of any Note or portion of a Note selected for redemption, except for
the unredeemed portion of any Note being redeemed in part.  Also, the Issuers
need not exchange or register the transfer of any Notes for a period of 15 days
before a selection of Notes to be redeemed or during the period between a record
date and the corresponding Interest Payment

          This Regulation S Temporary Global Note is exchangeable in whole or in
part for one or more Global Notes only (i) on or after the termination of the
40-day restricted period (as defined in Regulation S) and (ii) upon presentation
of certificates (accompanied by an Opinion of Counsel, if applicable) required
by Article 2 of the Indenture.  Upon exchange of this Regulation S Temporary
Global Note for one or more Global Notes, the Trustee shall cancel this
Regulation S Temporary Global Note.

          10.  Persons Deemed Owners.  The registered Holder of a Note may be
treated as its owner for all purposes.

          11.  Amendment, Supplement and Waiver.  Subject to certain exceptions,
the Indenture, the Guarantees or the Notes may be amended or supplemented with
the consent of the Holders of at least a majority in principal amount of the
then outstanding Notes voting as a single class and any existing default or
compliance with any provision of the Indenture, the Guarantees or the Notes may
be waived with the consent of the Holders of a majority in principal amount of
the then outstanding Notes voting as a single class.  Without the consent of any
Holder of a Note, the Indenture, the Guarantees or the Notes may be amended or
supplemented to cure any ambiguity, defect or inconsistency, to provide for
uncertificated Notes in addition to or in place of certificated Notes, to
provide for the assumption of the Issuers' or Guarantor's obligations to Holders
of the Notes in case of a merger or consolidation, to make any change that would
provide any additional rights or benefits to the Holders of the Notes or that
does not adversely affect the legal rights under the Indenture of any such
Holder, or to comply with the requirements of the Commission in order to effect
or maintain the qualification of the Indenture under the Trust Indenture Act 

                                     A-2-8

 
or to allow any Guarantor to execute a supplemental indenture to the Indenture
and/or a Guarantee with respect to the Notes.

          12.  Defaults and Remedies.  Each of the following constitutes an
Event of Default: (a) default for 30 days in the payment when due of interest
on, or Liquidated Damages, if any, with respect to, the Notes; (b) default in
payment when due of the principal of or premium, if any, on the Notes; (c)
failure by the Company or any of its Subsidiaries to make the offer required or
to purchase any of the Notes as required under the provisions described under
Section 4.10 or Section 4.15; (d) failure by the Company or any of its
Subsidiaries for 30 days after notice to comply with the provisions of Section
4.07 or Section 4.09, or failure by the Company or any of its Subsidiaries for
60 days after notice to comply with any of its other agreements in the Indenture
or the Notes; (e) default under any mortgage, indenture or instrument under
which there may be issued or by which there may be secured or evidenced any
Indebtedness for money borrowed by the Company or any of its Restricted
Subsidiaries (or the payment of which is guaranteed by the Company or any of its
Restricted Subsidiaries) whether such Indebtedness or guarantee now exists, or
is created after the date of this Indenture, which default (a) is caused by a
failure to pay principal of or premium, if any, or interest on such Indebtedness
prior to the expiration of the grace period provided in such Indebtedness on the
date of such default (a "Payment Default") or (b) results in the acceleration of
such Indebtedness prior to its express maturity and, in each case, the principal
amount of any such Indebtedness, together with the principal amount of any other
such Indebtedness under which there has been a Payment Default or the maturity
of which has been so accelerated, aggregates $25.0 million or more; (f) failure
by the Company or any of its Restricted Subsidiaries or any group of Restricted
Subsidiaries that, taken as a whole, would be a Significant Subsidiary to pay
final judgments aggregating in excess of $25.0 million, which judgments are not
paid, discharged or stayed for a period of 60 days; (g) except as permitted by
the Indenture, any Guarantee of the Notes shall be held in any judicial
proceeding to be unenforceable or invalid or shall cease for any reason to be in
full force and effect or any Guarantor, or any Person acting on behalf of any
Guarantor, shall deny or disaffirm its obligations under its Guarantee of the
Notes; and (h) certain events of bankruptcy or insolvency with respect to the
Company, any of its Significant Subsidiaries that are Restricted Subsidiaries or
any group of Restricted Subsidiaries that, taken as a whole, would be a
Significant Subsidiary.  If any Event of Default occurs and is continuing, the
Trustee or the Holders of at least 25% in principal amount of the then
outstanding Notes may declare all the Notes to be due and payable.
Notwithstanding the foregoing, in the case of an Event of Default arising from
certain events of bankruptcy or insolvency, all outstanding Notes will become
due and payable without further action or notice.  Holders may not enforce the
Indenture or the Notes except as provided in the Indenture.  Subject to certain
limitations, Holders of a majority in principal amount of the then outstanding
Notes may direct the Trustee in its exercise of any trust or power. The Trustee
may withhold from Holders of the Notes notice of any continuing Default or Event
of Default (except a Default or Event of Default relating to the payment of
principal or interest) if it determines that withholding notice is in their
interest.  The Hold-

                                     A-2-9

 
ers of a majority in aggregate principal amount of the Notes then outstanding by
notice to the Trustee may on behalf of the Holders of all of the Notes waive any
existing Default or Event of Default and its consequences under the Indenture
except a continuing Default or Event of Default in the payment of interest on,
or the principal of, the Notes. Each Issuer is required to deliver to the
Trustee annually a statement regarding compliance with the Indenture, and each
Issuer is required upon becoming aware of any Default or Event of Default, to
deliver to the Trustee a statement specifying such Default or Event of Default.

          13.  Trustee Dealings with Issuers.  The Trustee, in its individual or
any other capacity, may make loans to, accept deposits from, and perform
services for the Issuers or their Affiliates, and may otherwise deal with the
Issuers or their Affiliates, as if it were not the Trustee.

          14.  No Recourse Against Others.  A director, officer, employee,
incorporator or stockholder, of either Issuer, as such, shall not have any
liability for any obligations of the Issuers under the Notes or the Indenture or
for any claim based on, in respect of, or by reason of, such obligations or
their creation.  Each Holder 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.

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

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

          17.  Additional Rights of Holders of Restricted Global Notes and
Restricted Definitive Notes.  In addition to the rights provided to Holders of
Notes under the Indenture, Holders of Restricted Global Notes and Restricted
Definitive Notes shall have all the rights set forth in the Registration Rights
Agreement dated as of December 14, 1998, between the Issuers, the Guarantors and
the parties named on the signature pages thereof (the "Registration Rights
Agreement").

          18.  CUSIP Numbers.  Pursuant to a recommendation promulgated by the
Committee on Uniform Security Identification Procedures, the Issuers have caused
CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP numbers
in notices of redemption as a convenience to Holders.  No representation is made
as to the accuracy of such numbers either as printed on the Notes or as
contained in any notice of redemption and reliance may be placed only on the
other identification numbers placed thereon.

                                    A-2-10

 
          The Issuers will furnish to any Holder upon written request and
without charge a copy of the Indenture and/or the Registration Rights Agreement.

                             W I T N E S S E T H :
                             -------------------- 

          WHEREAS, the Issuers and the Guarantors have heretofore executed and
delivered to the Trustee an indenture (the "Indenture"), dated as of December
14, 1998 providing for the issuance of an aggregate principal amount of up to
$200.0 million of 10 1/2% Senior Notes due 2005 (the "Notes");

          WHEREAS, the Indenture provides that under certain circumstances the
Subsidiary Guarantor shall execute and deliver to the Trustee a supplemental
indenture pursuant to which the Subsidiary Guarantor shall unconditionally
guarantee all of the Issuers' Obligations under the Notes and the Indenture on
the terms and conditions set forth herein (the "Guarantee"); and

          WHEREAS, pursuant to Section 9.01 of the Indenture, the Trustee is
authorized to execute and deliver this Supplemental Indenture.

          NOW THEREFORE, in consideration of the foregoing and for other good
and valuable consideration, the receipt of which is hereby acknowledged, the

          2.   Agreement to Guarantee.  The Subsidiary Guarantor hereby agrees
as follows:

          (a)  Along with all Guarantors named in the Indenture, to jointly and
               severally Guarantee to each Holder of a Note authenticated and
               delivered by the Trustee and to the Trustee and its successors
               and assigns the Notes or the obligations of the Issuers hereunder
               or thereunder, that:

                                      F-1

 
               (i)  the principal of and interest on the Notes will be promptly
                    paid in full when due, whether at maturity, by acceleration,
                    redemption or otherwise, and interest on the overdue
                    principal of and interest on the Notes, if any, if lawful,
                    and all other obligations of the Issuers to the Holders or
                    the Trustee hereunder or thereunder will be promptly paid in
                    full or performed, all in accordance with the terms hereof
                    and thereof; and

               (ii) in case of any extension of time of payment or renewal of
                    any Notes or any of such other obligations, that same will
                    be promptly paid in full when due or performed in accordance
                    with the terms of the extension or renewal, whether at
                    stated maturity, by acceleration or otherwise. Failing
                    payment when due of any amount so guaranteed or any
                    performance so guaranteed for whatever reason, the
                    Guarantors shall be jointly and severally obligated to pay
                    the same immediately.

          (b)  The obligations hereunder shall be unconditional, irrespective of
               the validity, regularity or enforceability of the Notes or the
               Indenture, the absence of any action to enforce the same, any
               waiver or consent by any Holder of the Notes with respect to any
               provisions hereof or thereof, the recovery of any judgment
               against the Issuers, any action to enforce the same or any other
               circumstance which might otherwise constitute a legal or
               equitable discharge or defense of a guarantor.

          (c)  The following is hereby waived: diligence presentment, demand of
               payment, filing of claims with a court in the event of insolvency
               or bankruptcy of either Issuer, any right to require a proceeding
               first against either Issuer, protest, notice and all demands
               whatsoever.

          (d)  This Subsidiary Guarantee shall not be discharged except by
               complete performance of the obligations contained in the Notes
               and the Indenture, and the Guaranteeing Subsidiary accepts all
               obligations of a Guarantor under the Indenture.

          (e)  If any Holder or the Trustee is required by any court or
               otherwise to return to the Issuers, the Guarantors, or any
               Custodian, Trustee, liquidator or other similar official acting
               in relation to either the Issuers or the Guarantors, any amount
               paid by either to the Trustee or such Holder, this Subsidiary
               Guarantee, to the extent theretofore discharged, shall be
               reinstated in full force and effect.

                                      F-2

 
          (f)  The Subsidiary Guarantor shall not be entitled to any right of
               subrogation in relation to the Holders in respect of any
               obligations guaranteed hereby until payment in full of all
               obligations guaranteed hereby.

          (g)  As between the Guarantors, on the one hand, and the Holders and
               the Trustee, on the other hand, (x) the maturity of the
               obligations guaranteed hereby may be accelerated as provided in
               Article 6 of the Indenture for the purposes of this Subsidiary
               Guarantee, notwithstanding any stay, injunction or other
               prohibition preventing such acceleration in respect of the
               obligations guaranteed hereby, and (y) in the event of any
               declaration of acceleration of such obligations as provided in
               Article 6 of the Indenture, such obligations (whether or not due
               and payable) shall forthwith become due and payable by the
               Guarantors for the purpose of this Subsidiary Guarantee.

          (h)  The Guarantors shall have the right to seek contribution from any
               non-paying Guarantor so long as the exercise of such right does
               not impair the rights of the Holders under the Guarantee.

          (i)  Pursuant to Section 10.02 of the Indenture, after giving effect
               to any maximum amount and any other contingent and fixed
               liabilities that are relevant under any applicable Bankruptcy or
               fraudulent conveyance laws, and after giving effect to any
               collections from, rights to receive contribution from or payments
               made by or on behalf of any other Guarantor in respect of the
               obligations of such other Guarantor under Article 10 of the
               Indenture, this Guarantee shall be limited to the maximum amount
               permissible such that obligations of such Guarantor under this
               Guarantee will not constitute a fraudulent transfer or
               conveyance.

          3    Execution and Delivery. Each Subsidiary Guarantor agrees that the
Subsidiary Guarantees shall remain in full force and effect notwithstanding any
failure to endorse on each Note a notation of such Subsidiary Guarantee.

          4.   Subsidiary Guarantor May Consolidate, Etc. on Certain Terms.

          (a)  The Subsidiary Guarantor may not consolidate with or merge with
     or into (whether or not such Subsidiary Guarantor is the surviving Person)
     another corporation, Person or entity whether or not affiliated with such
     Subsidiary Guarantor unless:

               (i)    subject to Sections 10.04 and 10.05 of the Indenture, the
          Person formed by or surviving any such consolidation or merger (if
          other than such Subsidiary Guarantor) unconditionally assumes all the
          obligations of

                                      F-3

 
          such Subsidiary Guarantor pursuant to a supplemental indenture in form
          and substance reasonably satisfactory to the Trustee, under the Notes,
          the Indenture and the Registration Rights Agreement; and

               (ii)   immediately after giving effect to such transaction, no
          Default or Event of Default exists.

               (iii)  the Company would be permitted by virtue of the Company's
          pro forma Fixed Charge Coverage Ratio, immediately after giving effect
          to such transaction, to incur at least $1.00 of additional
          Indebtedness pursuant to the Fixed Charge Coverage Ratio test set
          forth in the first paragraph of Section 4.09 hereof.

          (b)  In case of any such consolidation, merger, sale or conveyance and
     upon the assumption by the successor corporation, by supplemental
     indenture, executed and delivered to the Trustee and satisfactory in form
     to the Trustee, of the Subsidiary Guarantee endorsed upon the Notes and the
     due and punctual performance of all of the covenants and conditions of the
     Indenture to be performed by the Subsidiary Guarantor, such successor
     corporation shall succeed to and be substituted for the Subsidiary
     Guarantor with the same effect as if it had been named herein as a
     Subsidiary Guarantor. Such successor corporation thereupon may cause to be
     signed any or all of the Subsidiary Guarantees to be endorsed upon all of
     the Notes issuable hereunder which theretofore shall not have been signed
     by the Issuers and delivered to the Trustee. All the Subsidiary Guarantees
     so issued shall in all respects have the same legal rank and benefit under
     the Indenture as the Subsidiary Guarantees theretofore and thereafter
     issued in accordance with the terms of the Indenture as though all of such
     Subsidiary Guarantees had been issued at the date of the execution hereof.

          (c)  Except as set forth in Articles 4 and 5 of the Indenture, and
     notwithstanding clause (a) above, nothing contained in the Indenture or in
     any of the Notes shall prevent any consolidation or merger of a Subsidiary
     Guarantor with or into the Issuers or another Subsidiary Guarantor, or
     shall prevent any sale or conveyance of the property of a Subsidiary
     Guarantor as an entirety or substantially as an entirety to the Issuers or
     another Subsidiary Guarantor.

          5.   Releases.

          (a)  In the event of a sale or other disposition of all of the assets
     of any Subsidiary Guarantor, by way of merger, consolidation or otherwise,
     a sale or other disposition of all to the capital stock of any Subsidiary
     Guarantor or the designation of a Subsidiary Guarantor as an Unrestricted
     Subsidiary in accordance with the terms of the Indenture, then such
     Subsidiary Guarantor (in the event of a sale or

                                      F-4

 
     other disposition, by way of merger, consolidation or otherwise, of all of
     the capital stock of such Subsidiary Guarantor) or the corporation
     acquiring the property (in the event of a sale or other disposition of all
     or substantially all of the assets of such Subsidiary Guarantor) will be
     released and relieved of any obligations under its Subsidiary Guarantee;
     provided that the Net Proceeds of such sale or other disposition are
     applied in accordance with the applicable provisions of the Indenture,
     including without limitation Section 4.10 of the Indenture. Upon delivery
     by each Issuer to the Trustee of an Officers' Certificate and an Opinion of
     Counsel to the effect that such sale or other disposition was made by the
     Issuer in accordance with the provisions of the Indenture, including
     without limitation Section 4.10 of the Indenture, the Trustee shall execute
     any documents reasonably required in order to evidence the release of any
     Subsidiary Guarantor from its obligations under its Subsidiary Guarantee.

          (b)  Any Subsidiary Guarantor not released from its obligations under
     its Subsidiary Guarantee shall remain liable for the full amount of
     principal of and interest on the Notes and for the other obligations of any
     Subsidiary Guarantor under the Indenture as provided in Article 10 of the
     Indenture.

          6.   No Recourse Against Others. No past, present or future director,
officer, employee, incorporator, stockholder or agent of the Subsidiary
Guarantor, as such, shall have any liability for any obligations of the Issuers
or any Subsidiary Guarantor under the Notes, any Subsidiary Guarantees, the
Indenture or this Supplemental Indenture or for any claim based on, in respect
of, or by reason of, such obligations or their creation. Each Holder of the
Notes by accepting a Note waives and releases all such liability. The waiver and
release are part of the consideration for issuance of the Notes. Such waiver may
not be effective to waive liabilities under the federal securities laws and it
is the view of the Commission that such a waiver is against public policy.

          7.   New York Law To Govern. THE INTERNAL LAW OF THE STATE OF NEW YORK
SHALL GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL INDENTURE BUT WITHOUT
GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT
THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

          8.   Counterparts. The parties may sign any number of copies of this
Supplemental Indenture. Each signed copy shall be an original, but all of them
together represent the same agreement.

          9.   Effect of Headings. The Section headings herein are for
convenience only and shall not affect the construction hereof.

          10.  The Trustee. The Trustee shall not be responsible in any manner
whatsoever for or in respect of the validity or sufficiency of this Supplemental
Indenture or 

                                      F-5

 
for or in respect of the recitals contained herein, all of which recitals are
made solely by the Subsidiary Guarantor and the Issuers.

                                      F-6

 
          IN WITNESS WHEREOF, the parties hereto have caused this Supplemental
Indenture to be duly executed and attested, all as of the date first above
written.
