                                   ARTICLE 1.

                   DEFINITIONS AND INCORPORATION BY REFERENCE

Section 1.1.  Definitions.
              ----------- 

          "Acquired Indebtedness" means Indebtedness of a Person (including an
Unrestricted Subsidiary) existing at the time such Person becomes a Restricted
Subsidiary or assumed in connection with the acquisition of assets from a
Person.

          "Acquisition EBITDA" means, without duplication, (i) EBITDA for the
last four fiscal quarters for which financial statements are available at the
date of determination (the "Acquisition EBITDA Period") with respect to a
business or Person which has been acquired by the Company or one of its
Restricted Subsidiaries or which is the subject of a binding acquisition
agreement requiring the calculation of EBITDA for purposes of Section 4.6 and,
in each case, with respect to which financial results on a consolidated basis
with the Company have not been made available for an entire fiscal quarter;
plus (ii) in connection with any such acquisition, projected quantifiable
improvements in operating results due to an established program of cost
reductions (consistent with the cost reductions actually achieved by the Company
in connection with prior acquisitions) adopted, in good faith, by the Company
or one of its Restricted Subsidiaries through a Board Resolution certified by
an Officers' Certificate filed with the Trustee (calculated on a pro forma
basis for the Acquisition EBITDA Period as if the program had been implemented
at the beginning of the Acquisition EBITDA Period), without giving effect to any
operating losses of the acquired Person.  Each such Officers' Certificate shall
be signed

 
by the Chief Financial Officer and another officer of the Company. The Trustee
may rely on such Officers' Certificate (subject to the provisions of Section
7.1 of this Indenture). Acquisition EBITDA of a business shall be a fixed number
determined as of the date the calculation of EBITDA for purposes of Section 4.6
is first required with respect to the acquisition of such business (the "Deter
mination Date") and shall be utilized from the Determination Date through the
date financial results are available for the first full fiscal quarter
following the acquisition (following which the actual EBITDA of such business or
Person shall be included in the EBITDA of the Company). For purposes of
determining Acquisition EBITDA with respect to the acquisition of a particular
business or Person, Acquisition EBITDA shall include not only the Acquisition
EBITDA of such business or Person, but also the Acquisition EBITDA of any
business previously acquired by the Company or the subject of a pending
acquisition agreement to the extent that, as of the Determina tion Date, the
financial results for such business or Person on a consolidated basis with the
Company for a full fiscal quarter subsequent to its acquisition by the Company
are not yet available.

          "Adjusted EBITDA" means for any Person, without duplication, the sum
of (a) EBITDA of such Person and its Restricted Subsidiaries for the most recent
fiscal quarter for which internal financial statements are available,
multiplied by four and (b) Acquisition EBITDA.

          "Adjusted Net Assets" of a Guarantor at any date shall mean the lesser
of the amount by which (x) the fair value of the property of such Guarantor
exceeds the total amount of liabilities, including, without limitation,
contingent liabilities (after giving effect to all other fixed and contingent
liabilities (including, without limitation, any guarantees of Senior
Indebtedness)), but excluding liabilities under the Guarantee, of such Guarantor
at such date and (y) the present fair salable value of the assets of such
Guarantor at such date exceeds the amount that will be required to pay the
proba ble liability of such Guarantor on its debts (after giving effect to all
other fixed and contingent liabilities (including, without limitation, any
guarantees of Senior Indebtedness) and after giving effect to any collection
from any Subsidiary of such Guarantor in

                                       2

 
respect of the obligations of such Subsidiary under the Guarantee), excluding
Indebtedness in respect of the Guarantee, as they become absolute and matured.

          "Affiliate" of any specified Person means any other Person which
directly or indirectly through one or more intermediaries controls, or is
controlled by, or is under common control with, such specified Person. For the
purposes of this definition, "control" (including, with correlative meanings,
the terms "controlling" "controlled by," and "under common control with"), as
used with respect to any Person, means the possession,  directly or indirectly,
of the power to direct or cause the direction of the management or policies of
such Person, whether through the ownership of voting securities, by agreement or
otherwise.

          "Agent" means any Registrar, Paying Agent, co-registrar or agent for
service of notices and demands.

          "Asset Sale" means the sale, transfer or other disposition (other than
to the Company or any of its Restricted Subsidiaries) in any single transaction
or series of related transactions involving assets with a fair market value in
excess of $500,000 of (a) any Capital Stock of or other equity interest in any
Restricted Subsidiary of the Company, (b) all or substantially all of the assets
of the Company or of any Restricted Subsidiary thereof, (c) real property of
the Company or a Restricted Subsidiary or (d) all or substantially all of the
assets of any business property, or part thereof, owned by the Company or any
Restricted Subsidiary thereof, or a division, line of business or comparable
busi ness segment of the Company or any Restricted Subsidiary thereof; provided
                                                                       --------
that Asset Sales shall not include (i) sales, leases, conveyances, transfers or
other dispositions to the Company or to a Restricted Subsidiary or to any other
Person if after giving effect to such sale, lease, conveyance, transfer or other
disposition such other Person becomes a Restricted Subsidiary, (ii) trans
actions complying with Section 5.1 and (iii) transfers or other distributions of
assets which constitute (1) Permitted Investments or (2) Restricted Payments
made in compliance with Section 4.9.

          "Asset Sale Proceeds" means, with respect to

                                       3

 
any Asset Sale, (i) cash received by the Company or any Restricted Subsidiary
from such Asset Sale (including cash received as consideration for the
assumption of liabilities incurred in connection with or in anticipation of
such Asset Sale), after (a) provision for all income or other taxes measured by
or resulting from such Asset Sale; (b) payment of all brokerage commissions,
underwriting and other fees and expenses related to such Asset Sale, (c)
provision for minority interest holders in any Restricted Subsidiary as a result
of such Asset Sale, (d) payments made to retire Indebtedness secured by the
assets subject to such Asset Sale and (e) deduction of appropriate amounts to be
provided by the Company or a Restricted Subsidiary as a reserve, in accordance
with GAAP, against any liabilities associated with the assets sold or disposed
of in such Asset Sale and retained by the Company or a Restricted Subsidiary
after such Asset Sale, including, without limitation, pension and other post-
employment benefit liabilities and liabilities related to environmental matters

the Depository, as hereinafter provided.

Section 2.2.   Execution and Authentication.
               ---------------------------- 

          The aggregate principal amount of Notes which may be authenticated and
delivered under the Indenture is $120,000,000.

                                       29

 
          The Notes shall be executed on behalf of the Company by two Officers
of the Company or an Officer and an Assistant Secretary of the Company.  Such
signatures may be either manual or facsimile.  The Company's seal shall be
impressed, affixed, imprinted or reproduced on the Notes and may be in facsimile
form.

          If an Officer whose signature is on a Note no longer holds that office
at the time the Trustee authenticates the Note or at anytime thereafter, the
Note shall be valid nevertheless.

          A Note shall not be valid until the Trustee manually signs the
certificate of authentication on the Note.  Such signature shall be conclusive
evidence that the Note has been authenticated under this Indenture.

          The Trustee or an authenticating agent shall authenticate Notes for
original issue in the aggregate principal amount of $120,000,000 upon a Company
Request.  The aggregate principal amount of Notes outstanding at any time may
not exceed such amount except as provided in Section 2.7 hereof. The Notes shall
be issuable only in registered form without coupons and only in denominations of
$1,000 and integral multiples thereof.

          The Trustee may appoint an authenticating agent acceptable to the
Company to authenticate Notes.  Unless limited by the terms of such appointment,
an authenticating agent may authenticate Notes whenever the Trustee may do so.
Each reference in this Indenture to authentication by the Trustee includes
authentication by such agent.  Such authenticating agent shall have the same
right as the Trustee in dealing with the Company or an Affiliate.

Section 2.3.   Registrar and Paying Agent.
               -------------------------- 

          The Company shall appoint a registrar, which shall maintain an office
or agency where Notes may be presented for registration of transfer or for
exchange ("Registrar"), and a paying agent, which shall maintain an office or
agency located in the Borough of Manhattan, City of New York, State of New York
where Notes may be presented for payment ("Paying Agent") and shall maintain

                                       30

 
an office or agency where notices and demands to or upon the Company in respect
of the Notes and this Indenture may be served. The Registrar shall keep a
register of the Notes and of their transfer and exchange. The Company may
appoint one or more co-registrars and one or more additional paying agents.
Neither the Company nor any Affiliate may act as Paying Agent. The Company may
change any Paying Agent, Registrar or co-registrar without notice to any
Noteholder.

          The Company shall enter into an appropriate agency agreement with any
Registrar or Paying Agent not a party to this Indenture.  The agreement shall
implement the provisions of this Indenture that relate to such Agent.  The
Company shall notify the Trustee of the name and address of any such Agent.  If
the Company fails to maintain a Registrar or Paying Agent, or agent for service
of notices and demands, or fails to give the foregoing notice, the Trustee
shall act as such and shall be entitled to appropriate compensation pursuant to
Section 7.7.  The Company initially appoints the Trustee as Registrar, Paying
Agent and agent for service of notices and demands in connection with the Notes.

                                       31

 
Section 2.4.   Paying Agent to Hold Money in Trust.
               ----------------------------------- 

          On or before each due date of the principal and interest on any Notes,
the Company shall deposit with the Paying Agent a sum sufficient to pay such
principal and interest so becoming due.  Each Paying Agent shall hold in trust
for the benefit of the Noteholders or the Trustee all money held by the Paying
Agent for the payment of principal of or interest on the Notes (whether such
money has been paid to it by the Company or any other obligor on the Notes), and
the Company and the Paying Agent shall notify the Trustee of any default by the
Company (or any other obligor on the Notes) in making any such payment. Money
held in trust by the Paying Agent need not be segregated except as required by
law and in no event shall the Paying Agent be liable for any interest on any
money received by it hereunder.  The Company at any time may require a Paying
Agent to pay all money held by it to the Trustee and the Trustee, may at any
time during the continuance of any Payment Default, upon written request to a
Paying Agent, require such Paying Agent to forthwith pay to the Trustee all sums
so held in trust by such Paying Agent together with a complete accounting of
such sums.  Upon doing so, the Paying Agent shall have no further liability for
the money delivered to the Trustee.

Section 2.5.   Noteholder Lists.
               ---------------- 

          The Trustee shall preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
Noteholders.  If the Trustee is not the Registrar, the Company shall furnish to
the Trustee on or before each January 1 and July 1 in each year, and at such
other times as the Trustee may request in writing, a list in such form and as of
such date as the Trustee may reasonably require of the names and addresses of
Noteholders, including the aggregate principal amount of Notes held by each such
Noteholder.

Section 2.6.   Transfer and Exchange.
               --------------------- 

          When a Note is presented to the Registrar with a request to register
the transfer thereof, the Registrar shall register the transfer as requested if
the require-

                                       32

 
ments of applicable law are met and, when Notes are presented to the
Registrar with a request to exchange them for an equal principal amount of Notes
of other authorized denominations, the Registrar shall make the exchange as
requested provided that every Note presented or surrendered for registration of
transfer or exchange shall be duly endorsed or be accompanied by a written
instrument of transfer in form satisfactory to the Company and the Registrar
duly executed by the Holder thereof or his attorney, duly authorized in writing.
To permit registration of transfers and exchanges, upon surrender of any Note
for registration of transfer or exchange at the office or agency maintained
pursuant to Section 2.3 hereof, the Company shall issue and execute and the
Trustee shall authenticate and make available for delivery Notes at the
Registrar's request in the name of the transferee or Holder, as the case may be,
designated by the Registrar. Any exchange or transfer shall be without any
service charge to the Noteholder, except that the Company may require payment by
the Holder of a sum sufficient to cover any tax or other governmental charge
that may be imposed in relation to a transfer or exchange, but this provision
shall not apply to any exchange pursuant to Section 2.9, 3.6 or 8.5 hereof. The
Registrar shall not be required to register transfers of Notes or to exchange
Notes for a period of 15 days before the day of mailing of the notice of
redemption of any Notes to be redeemed. The Registrar shall not be required to
exchange or register transfers of any Notes called or being called for
redemption in whole or in part, except the unredeemed portion of any Note being
redeemed in part.

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

          Neither the Trustee nor the Registrar shall have any duty to monitor
the Company's compliance with or have any responsibility with respect to the
Company's compliance with any Federal or state securities laws.

Section 2.7.  Replacement Notes.
              ----------------- 

                                       33

 
          If a mutilated Note is surrendered to the Registrar or Trustee or if
the Holder of a Note presents evidence to the satisfaction of the Company and
the Trustee that the Note has been lost, destroyed or wrongfully taken and of
the ownership thereof, the Company shall issue and the Trustee shall
authenticate a replacement Note if the requirements of Section 8-405 of the New
York Uniform Commercial Code as in effect on the date of this Indenture are met.
An indemnity bond may be re quired by the Company or the Trustee that is
sufficient in the judgment of the Company and the Trustee to protect the
Company, the Trustee or any Agent from any loss which any of them may suffer if
a Note is replaced. The Company and the Trustee each may charge for its
expenses (including reasonable attorneys' fees and expenses) in replacing a
Note. Every replacement Note is an additional obligation of the Company.

Section 2.8.  Outstanding Notes.
              ----------------- 

          Notes outstanding at any time are all Notes authenticated by the
Trustee except for those cancelled by it, those delivered to it for
cancellation, and those described in this Section 2.8 as not outstanding.

          If a Note is replaced pursuant to Section 2.7, it ceases to be
outstanding until the Company and the Trustee receive proof satisfactory to each
of them that the replaced Note is held by a bona fide purchaser.

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

          Subject to Section 13.6, a Note does not cease to be outstanding
solely because the Company or an Affiliate holds the Note.

Section 2.9.  Temporary Notes.
              --------------- 

                                       34

 
          Until definitive Notes are ready for delivery, the Company may prepare
and the Trustee shall authenticate temporary Notes.  Temporary Notes shall be
substantially in the form, and shall carry all rights, benefits and privileges,
of definitive Notes but may have variations that the Company considers
appropriate for temporary Notes. Without unreasonable delay, the Company shall
prepare and the Trustee shall authenticate definitive Notes in exchange for
temporary Notes presented to it.

Section 2.10.  Cancellation.
               ------------ 

          The Company at any time may deliver Notes to the Trustee for
cancellation.  The Registrar and the Paying Agent shall forward to the Trustee
any Notes surrendered to them for transfer, exchange or payment.  The Trustee
shall cancel and retain or, upon written request of the Company, return to the
Company, in accordance with its normal practice, all Notes surrendered for
transfer, exchange, payment or cancellation.  Subject to Section 2.7 hereof, the
Company may not issue new Notes to replace Notes in respect of which it has
previously paid all principal, premium and interest accrued thereon, or
delivered to the Trustee for cancellation.

                                       35

 
Section 2.11.  Defaulted Interest.
               ------------------ 

          If the Company defaults in a payment of interest on the Notes, it
shall pay the defaulted amounts, plus (to the extent permitted by law) any
interest payable on defaulted amounts pursuant to Section 4.1 hereof, to the
persons who are Noteholders on a subsequent special record date.  The Company
shall fix the special record date and payment date in a manner satisfactory to
the Trustee and provide the Trustee at least 20 days notice of the proposed
amount of default interest to be paid and the special payment date.  At least 15
days before the special record date, the Company shall mail or cause to be
mailed to each Noteholder at his address as it appears on the Notes register
maintained by the Registrar a notice that states the special record date, the
payment date (which shall be not less than five nor more than ten days after the
special record date), and the amount to be paid.  In lieu of the foregoing
procedures, the Company may pay defaulted interest in any other lawful manner
satisfactory to the Trustee.

Section 2.12.  Deposit of Moneys.
               ----------------- 

          Prior to 10:00 a.m., New York City time, on each Interest Payment Date
and Maturity Date, the Company shall have deposited with the Paying Agent in
immediately available funds money sufficient to make cash payments, if any, due
on such Interest Payment Date or Maturity Date, as the case may be, in a timely
manner which permits the Trustee to remit payment to the Holders on such
Interest Payment Date or Maturity Date, as the case may be.  The principal and
interest on Global Notes shall be payable to the Depository or its nominee, as
the case may be, as the sole registered owner and the sole holder of the Global
Notes represented thereby.  The principal and interest on Physical Notes shall
be payable at the office of the Paying Agent.

Section 2.13.  CUSIP Number.
               ------------ 

          The Company in issuing the Notes may use a "CUSIP" number(s), and if
so, the Trustee shall use the CUSIP number(s) in notices of redemption or
exchange as a convenience to Holders, provided that any such notice may 
                                      --------                               

                                       36

 
state that no representation is made as to the correctness or accuracy of the
CUSIP number(s) printed in the notice or on the Notes, and that reliance may be
placed only on the other identification numbers printed on the Notes. The
Company will promptly notify in writing the Trustee of any such CUSIP number
used by the Company in connection with the Notes and any change in such CUSIP
number.

Section 2.14.  Book-Entry Provisions for Global Notes.
               -------------------------------------- 

          (a)  The Global Notes shall (i) be registered in the name of the
Depository or the nominee of such Depository, (ii) be delivered to the Trustee
as custodian for such Depository and (iii) bear the legend as set forth in
Exhibit B.

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

          (b)  Transfers of Global Notes shall be limited to transfer in whole,
but not in part, to the Depository, its successors or their respective nominees.
Certificated Notes (the "Physical Notes") shall be transferred to all
beneficial owners in exchange for their beneficial interests in Global Notes if
(i) the Depository notifies the Company that it is unwilling or unable to
continue as Depository for any Global Note and a successor depositary is not
appointed by the Company within 90 days of such notice or (ii) an Event of
Default has occurred and is continuing and the Registrar has received a written
request from the Depository to issue Physical Notes.

                                       37

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

          (d)  In connection with the transfer of Global Notes as an entirety to
beneficial owners pursuant to paragraph (b), the Global Notes shall be deemed to
be surrendered to the Trustee for cancellation, and the Company shall execute,
and the Trustee shall authenticate and deliver, to each beneficial owner
identified by the Depository in writing in exchange for its beneficial interest
in the Global Notes, an equal aggregate principal amount of Physical Notes of
authorized denominations.

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

redemption, (ii) at least 45 days prior to the Redemption Date in the case of a
total redemption or (iii) during such other period as the Trustee may agree to

Section 3.7 hereof, as appropriate.

Section 3.2.   Selection by Trustee of Notes to Be Re deemed.
               --------------------------------------------- 

          In the event that fewer than all of the Notes are to be redeemed, the
Trustee shall select the Notes to be redeemed, if the Notes are listed on a
national securities exchange, in accordance with the rules of such exchange or,
if the Notes are not so listed, on either a pro rata basis or by lot, or such
other method as it shall deem fair and appropriate; provided, however, that if a
                                                    --------  -------           
partial redemption is made with the proceeds of a Public Equity Offering,
selection of the Notes or portion thereof for redemption shall be made by the
Trustee on a pro rata basis, unless such a method is prohibited by law or by the
             --- ----                                                           
rules of such national securities exchange.  The Trustee shall promptly notify
the Company of the Notes selected for redemption and, in the case of any Notes
selected for partial redemption, the principal amount thereof to be redeemed.
The Trustee may select for redemption portions of the principal of the Notes
that have denominations larger than $1,000.  Notes and portions thereof the
Trustee selects shall be redeemed in amounts of $1,000 or whole multiples of
$1,000. For all purposes of this Indenture unless the context otherwise
requires, provisions of this Indenture that apply to Notes called for redemption
also apply to portions of Notes called for redemption.

Section 3.3.  Notice of Redemption.
              -------------------- 

          At least 30 days, but no more than 60 days, before a Redemption Date,
the Company shall mail, or cause to be mailed, a notice of redemption by first-
class mail to each Holder of Notes to be redeemed at his or her last address as
the same appears on the registry books maintained by the Registrar pursuant to
Section 2.3 hereof.

          The notice shall identify the Notes to be redeemed (including the
CUSIP numbers thereof) and shall state:

                                       39

 
     (1) the Redemption Date;

     (2) the redemption price;

     (3) 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 and upon
surrender of such Note, a new Note or Notes in principal amount equal to the
unredeemed portion will be issued;

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

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

redemption in the Company's name and at the Company's sole expense.

                                       40

 
Section 3.4.  Effect of Notice of Redemption.
              ------------------------------ 

          Once the notice of redemption described in Section 3.3 is mailed,
Notes called for redemption become due and payable on the Redemption Date and at
the redemption price, including any premium, plus interest accrued to the
Redemption Date.  Upon surrender to the Paying Agent, such Notes shall be paid
at the redemption price, including any premium, plus interest accrued to the
Redemption Date, provided that if the Redemption Date is after a regular
                 --------                                               
interest payment record date and on or prior to the Interest Payment Date, the
accrued interest shall be payable to the Holder of the redeemed Notes registered
on the relevant record date, and provided, further, that if a Redemption Date is
                                 --------  -------

no interest shall accrue for the period from such Redemption Date to such
succeeding Business Day.

Section 3.5.  Deposit of Redemption Price.

funds money sufficient to pay the redemption price of and accrued interest on
all Notes to be redeemed on that date other than Notes or portions thereof
called for redemption on that date which have been delivered by the Company to
the Trustee for cancellation.

          On and after any Redemption Date, if money sufficient to pay the
redemption price of and accrued interest on Notes called for redemption shall
have been made available in accordance with the preceding paragraph and payment
thereof is not prohibited pursuant to the terms of this Indenture, the Notes
called for redemption will cease to accrue interest and the only right of the
Holders of such Notes will be to receive payment of the redemption price of and,
subject to the first proviso in Section 3.4, accrued and unpaid interest on such
Notes to the Redemption Date.  If any Note called for redemption shall not be so
paid, interest will be paid, from the Redemption Date until such redemption
payment is made, on the unpaid principal of the Note and any interest not paid
on such unpaid principal, in each case, at the rate

                                       41

 
and in the manner provided in the Notes.

Section 3.6.  Notes Redeemed in Part.
              ----------------------

any such redemption occurs within 90 days following the closing of any such
Public Equity Offering.

the annual reports and of the information, documents and other reports (or
copies of such portions of any of the foregoing as the SEC may by rules and
regulations prescribe) which the Company files with the SEC pursuant to Section

receipt of such shall not constitute constructive notice of any information
contained therein or determinable from information contained therein, including
the Company's compliance with any of its covenants hereunder (as to which the
Trustee is entitled to rely exclusively on Officers' Certificates).

          (b)  The Company will transmit to all Holders, 

                                       43

 
in the manner and to the extent provided in TIA Section 313(c), within 30 days

Section 4.3.  Waiver of Stay, Extension or Usury Laws.
              --------------------------------------- 

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

Section 4.4.  Compliance Certificate.
              ---------------------- 

          (a)  The Company shall deliver to the Trustee, within 100 days after
the end of each fiscal year and on or before 50 days after the end of the first,
second and third quarters of each fiscal year, an Officers' Certificate (one of
the signers of which shall be the principal executive officer, principal
financial officer or principal accounting officer of the Company) stating that
a review of the activities of the Company and its Subsidiaries during such
fiscal year or fiscal quarter, as the case may be, has been made under the
supervision of the signing Officers with a view to determining whether the
Company has kept, observed, performed and fulfilled its obligations under this
Indenture, and further stating, as to each such Officer signing such
certificate, that to the best of his or her knowledge the Company has kept,
observed, performed and fulfilled each and every covenant contained in this
Indenture and is not in default in the 

                                       44

 
performance or observance of any of the terms, provisions and conditions hereof
(or, if a Default or Event of Default shall have occurred, describing all or
such Defaults or Events of Default of which he or she may have knowledge and
what action the Company is taking or proposes 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 are prohibited or, if such event has occurred, a
description of the event and what action the Company is taking or proposes to
take with respect thereto.

          (b)  So long as (and to the extent) not contrary to the then current
recommendations of the American Institute of Certified Public Accountants, the
year-end financial statements delivered pursuant to Section 4.2 above shall be
accompanied by a written statement of the Company's independent public
accountants (who shall be a firm of established national reputation) that in
making the examination necessary for certification of such financial statements
nothing has come to their attention which would lead them to believe that the
Company has violated any provisions of this Article 4 or Article 5 of this
Indenture 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 for any failure to obtain knowledge of any such
violation.

          (c)  The Company will, so long as any of the Notes are outstanding,
deliver to the Trustee, forthwith 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 Company is taking or proposes to take with
respect thereto.

Section 4.5.  Taxes.
              ----- 

          The Company shall, and shall cause each of its Subsidiaries to, pay

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

                                       45

 
          The Company will not, and will not permit any Restricted Subsidiary of
the Company to, directly or indirectly, incur any Indebtedness (including
Acquired Indebtedness) unless (a) after giving effect to the incurrence of such
Indebtedness and the receipt and application of the proceeds thereof, the ratio
of total Indebtedness of the Company and its Restricted Subsidiaries to the 
Company's Adjusted EBITDA is less than 6.0 to 1; provided, however, that if the
                                                 --------  -------
Indebtedness which is the subject of a determination under this provision is
Acquired Indebtedness, or Indebtedness incurred in connection with the
simultaneous acquisition of any Person, business, property or assets, then such 
ratio shall be determined by giving effect (on a pro forma basis, as if the
                                                 --- -----          
transaction had occurred at the beginning of the four quarter period ending at
the end of the last fiscal quarter of such Person or business for which
financial statements are available) to the incurrence or assumption of such
Acquired Indebtedness or such other Indebtedness by the Company; and (b) no
Default or Event of Default shall have occurred and be continuing at the time or
as a consequence of the incurrence of such Indebtedness.

          Notwithstanding the foregoing, the Company and its Restricted
Subsidiaries may incur Permitted Indebtedness; provided, that the Company will
                                               --------                       
not incur any Permitted Indebtedness, without meeting the Indebtedness
incurrence provisions of the preceding paragraph, that ranks pari passu or
                                                             ---- -----   
junior in right of payment to the Notes and that has a maturity or mandatory
sinking fund payment prior to the maturity of the Notes.

          Notwithstanding the two preceding paragraphs, the Company will not
permit any of its foreign Subsidiaries to incur any subordinated Indebtedness.

Section 4.7.   Limitation on Preferred Stock of Restrict ed Subsidiaries.
               --------------------------------------------------------- 

          The Company will not permit any Restricted Subsidiary to issue any
Preferred Stock (except Preferred Stock to the Company or a Restricted
Subsidiary) or permit any Person (other than the Company or a Subsidiary) to
hold any such Preferred Stock unless the Company or such Restricted Subsidiary
would be entitled to incur or assume Indebtedness under Section 4.6 hereof in

                                       46

 
the aggregate principal amount equal to the aggregate liqui dation value of the
Preferred Stock to be issued; provided, however, that any Restricted Subsidiary
                              --------  -------                                
that guarantees the Notes pursuant to Section 4.14 shall be permitted to 
issue Preferred Stock that is not Disqualified Capital Stock.

Section 4.8.   Limitation on Capital Stock of Restricted Subsidiaries.
               ------------------------------------------------------ 

          The Company will not (i) sell, pledge, hypothecate or otherwise
convey or dispose of any Capital Stock of a Restricted Subsidiary (other than
under the terms of the Credit Facility, under the terms of any Designated Senior
Indebtedness or as permitted in Section 4.12 hereof) or (ii) permit any of its
Restricted Subsidiaries to issue any Capital Stock, other than to the Company or
a Wholly-Owned Subsidiary of the Company.  The foregoing restrictions shall not
apply to an Asset Sale made in compliance with Section 4.10 hereof or the
issuance of Preferred Stock in compliance with Section 4.7 hereof.

Section 4.9.  Limitation on Restricted Payments.
              --------------------------------- 

          The Company will not make, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, make, any Restricted Payment, unless:

          (a)  no Default or Event of Default shall have occurred and be
     continuing at the time of or immediately after giving effect to such
     Restricted Payment;

          (b)  immediately after giving pro forma effect to such Restricted
                                        --- -----                          
     Payment, the Company could incur $1.00 of additional Indebtedness (other
     than Permitted Indebtedness) under Section 4.6 hereof; and

          (c)  immediately after giving effect to such Restricted Payment, the
     aggregate of all Restricted Payments declared (except to the extent not
     made on the payment date) or made after the Issue Date does not exceed the
     sum of (1) 50% of the cumulative Consolidated Net Income of the Company
     subsequent to the Issue Date (or minus 100% of any cumulative deficit in
     Consolidated Net Income during such

                                       47

 
     period) and (2) 100% of the aggregate Net Proceeds and the fair market
     value of securities or other property received by the Company from the
     issue or sale, after the Issue Date, of Capital Stock (other than
     Disqualified Capital Stock or Capital Stock of the Company issued to any
     Subsidiary of the Company) of the Company or any Indebtedness or other
     securities of the Company convertible into or exercisable or exchangeable
     for Capital Stock (other than Dis qualified Capital Stock) of the Company
     which has been so converted or exercised or exchanged, as the case may be,
     and (3) $3,000,000. For purposes of determining under this clause (c) the
     amount expended for Restricted Payments, cash distributed shall be valued
     at the face amount thereof and property other than cash shall be valued at
     its fair market value.

          Notwithstanding the foregoing, the provisions of this Section 4.9
shall not prohibit (i) the payment of any distribution within 60 days after the
date of declaration thereof, if at such date of declaration such payment would
comply with the provisions of this Indenture, (ii) the retirement of any shares
of Capital Stock of the Company or subordinated Indebtedness by conversion into,
or by or in exchange for, shares of Capital Stock (other than Disqualified
Capital Stock), or out of, the Net Proceeds of the substantially concurrent sale
(other than to a Subsidiary of the Company) of other shares of Capital Stock of
the Company (other than Disqualified Capital Stock), (iii) the redemption or
retirement of Indebtedness of the Company subordinated to the Notes in exchange
for, by conversion into, or out of the Net Proceeds of, a substantially
concurrent sale or incurrence of Indebtedness (other than any Indebtedness owed
to a Subsidiary) of the Company that is contractually subordinated in right of
payment to the Notes to at least the same extent as the subordinated
Indebtedness being redeemed or retired, (iv) the retirement of any shares of
Disqualified Capital Stock by conversion into, or by exchange for, shares of
Disqualified Capital Stock, or out of the Net Proceeds of the substantially
concur rent sale (other than to a Subsidiary of the Company) of other shares of
Disqualified Capital Stock, (v) Permitted Tax Distributions, (vi) additional
payments to employees of the Company for repurchases of, 

                                       48

 
stock or repurchases pursuant to the Company's Nonqualified Stock Option Plan;
provided, however, that the aggregate amount of all such payments under this
- --------  -------
clause (vi) does not exceed $2,000,000 in the aggregate, exclusive of amounts
funded by insurance proceeds; and provided, further, that with respect to clause
                                  --------  -------
(vi) (other than with respect to payments funded by insurance proceeds) no
Default or Event of Default shall have occurred and be continuing at the time of
any such distribution or payment or will occur immediately after giving effect
to any such distribution or payment; and provided, further, that, in determining
                                         --------  -------
the aggregate amount of all Restricted Payments made subsequent to the Issue
Date, all distributions or payments made pursuant to clause (vi) (exclusive of
insurance proceeds) shall be included.

          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 this Section 4.9 were computed, which calculations may
be based upon the Company's latest available financial statements, and that no
Default or Event of Default exists and is continuing and no Default or Event of
Default will occur immediately after giving effect to any Restricted Payments.

                                       49

 
Section 4.10.  Limitation on Certain Asset Sales.
               --------------------------------- 

          (a)  The Company will not, and will not permit any of its Restricted
Subsidiaries to, consummate an Asset Sale unless (i) the Company or its
Restricted Subsidiaries, as the case may be, receives consideration at the time
of such sale or other disposition at least equal to the fair market value
thereof (as determined for Asset Sales other than eminent domain, condemnation
or similar government proceedings in good faith by the Company's board of
directors, and evidenced by a board resolution); (ii) not less than 85% of the
consideration received by the Company or its Subsidiaries, as the case may be,
is in the form of cash or Temporary Cash Investments; and (iii) the Asset Sale
Proceeds received by the Company or such Restricted Subsidiary are applied (a)
first, to the extent the Company elects, or is required, to prepay, repay or
purchase debt under any then existing Senior Indebtedness of the Company or any
Restricted Subsidiary within 180 days following the receipt of the Asset Sale
Proceeds from any Asset Sale; (b) second, to the extent of the balance of Asset
Sale Proceeds after application as described above, to the extent the Company
elects, to an investment in assets (including Capital Stock or other securities
purchased in connection with the acquisition of Capital Stock or property of
another Person) used or useful in businesses similar or ancillary to the
business of the Company or Restricted Subsidiary as conducted at the time of
such Asset Sale, provided that such investment occurs or the Company or a
Restricted Subsidiary enters into contractual commitments to make such
investment, subject only to customary conditions (other than the obtaining of
financing), on or prior to the 181st day following receipt of such Asset Sale
Pro ceeds (the "Reinvestment Date") and Asset Sale Proceeds contractually
committed are so applied within 270 days following the receipt of such Asset
Sale Proceeds; and (c) third, if on the Reinvestment Date with respect to any
Asset Sale, the Available Asset Sale Proceeds exceed $10 million, the Company
shall apply an amount equal to such Available Asset Sale Proceeds to an offer to
repurchase the Notes, or any future Indebtedness ranking pari passu with the
Notes, which Indebtedness contains similar provisions requiring the Company to
repurchase such Indebtedness at a purchase price in cash equal to 100% of the
principal amount thereof plus accrued and unpaid interest, if any, to the date
of repurchase (an "Excess Proceeds Offer"); provided, however, that prior to
making

                                       50

 
any such Excess Proceeds Offer, the Company may, to the extent required pursuant
to the terms of Indebtedness outstanding as of the Issue Date, offer to use such
Available Asset Sale Proceeds to repurchase and use all or a portion of such
Available Asset Sale Proceeds to repurchase such Indebtedness. If an Excess
Proceeds Offer is not fully subscribed, the Company may retain the portion of
the Available Asset Sale Proceeds not required to repurchase Notes for general
corporate purposes. If the aggregate principal amount of Notes tendered pursuant
to such Excess Proceeds Offer is more than the amount of the Available Asset
Sale Proceeds, the Notes tendered will be repurchased on a pro rata basis or by
such other method as the Trustee shall deem fair and appropriate.

          (b)  If the Company is required to make an Excess Proceeds Offer, the
Company shall mail, within 30 days following the Reinvestment Date (or within
120 days following the Reinvestment Date if the Company is required to make an
offer to purchase Indebtedness (other than the Notes) outstanding as of the
Issue Date), a notice to the Holders stating, among other things: (1) that such
Holders have the right to require the Company to apply the Available Asset Sale
Proceeds to repurchase such Notes at a purchase price in cash equal to 100% of
the principal amount thereof plus accrued and unpaid interest, if any, to the
date of purchase; (2) the purchase date (the "Purchase Date"), which shall be
no earlier than 30 days and not later than 60 days from the date such notice is
mailed; (3) the instructions, deter mined by the Company, that each Holder must
follow in order to have such Notes repurchased; and (4) the calculations used
in determining the amount of Available Asset Sale Proceeds to be applied to the
repurchase of such Notes.  The Excess Proceeds Offer shall remain open for a
period of 20 Business Days following its commencement (the "Offer Period").  The
notice, which shall govern the terms of the Excess Proceeds Offer, shall state:

          (1)  that the Excess Proceeds Offer is being made pursuant to this
     Section 4.10 and the length of time the Excess Proceeds Offer will remain
     open;

          (2)  the purchase price and the Purchase Date;

          (3)  that any Note not tendered or accepted for 

                                       51

 
               payment will not be purchased and will continue to accrue 
     interest;

          (4)  that any Note accepted for payment pursuant to the Excess
     Proceeds Offer shall cease to accrue interest on and after the Purchase
     Date so long as payment thereof is not prohibited pursuant to the terms of
     the Indenture;

          (5)  that Holders electing to have a Note purchased pursuant to any
     Excess Proceeds Offer will be required to surrender the Note, with the form
     entitled "Option of Holder to Elect Purchase" on the reverse of the Note
     completed, to the Company, a depositary, if appointed by the Company, or a
     Paying Agent at the address specified in the notice at least three Business
     Days before the Purchase Date;

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

          (7)  that, if the aggregate principal amount of Notes surrendered by
     Holders exceeds the Available Asset Sale Proceeds, the Trustee shall select
     the Notes to be purchased on a pro rata basis (with such adjustments as may
     be deemed appropriate by the Company so that only Notes in denominations of
     $l,000, or integral multiples thereof, shall be purchased) or by such other
     method as the Trustee shall deem fair and appropriate; and

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

          On or before the Purchase Date, the Company shall, to the extent
lawful, accept for payment, on a pro rata basis or by such other method as the
Trustee shall 

                                       52

 
deem fair and appropriate to the extent necessary, Notes or portions thereof
tendered pursuant to the Excess Proceeds Offer, and deposit with the Paying
Agent U.S. legal tender sufficient to pay the purchase price plus accrued
interest, if any, on the Notes to be purchased and deliver to the Trustee an
Officers' Certificate stating that such Notes or portions thereof were accepted
for payment by the Company in accordance with the terms of this Section 4.10.
The Paying Agent shall promptly (but in any case not later than 5 days after the
Purchase Date) mail or deliver to each tendering Holder an amount equal to the
purchase price of the Note tendered by such Holder and accepted by the Company
for purchase, and the Company shall promptly issue a new Note, and the Trustee
shall authenticate and mail or make available for delivery such new Note to
such Holder equal in principal amount to any unpurchased portion of the Note
surrendered. Any Note not so accepted shall be promptly mailed or delivered by
the Company to the Holder thereof. The Company will publicly announce the
results of the Excess Proceeds Offer on the Purchase Date; provided, however, 
                                                           --------  -------
that prior to making any such Excess Proceeds Offer, the Company may, to the
extent required pursuant to the terms of Indebtedness outstanding as of the
Issue Date, offer to use such Available Asset Sale Proceeds to repurchase and
use all or a portion of such Available Asset Sale Proceeds to repurchase such
Indebtedness. If an Excess Proceeds Offer is not fully subscribed, the Company
may retain the portion of the Available Asset Sale Proceeds not required to
repurchase Notes for general corporate purposes.

Section 4.11.  Limitation on Transactions with Affiliates.
               ------------------------------------------ 

          (a)  The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, enter into any transaction or series
of related transactions (including, without limitation, the sale, purchase,
exchange or lease of assets, property or services) with any Affiliate
(including entities in which the Company or any of its Restricted Subsidiaries
own a minority interest) or holder of 10% or more of the Company's Common Stock
(an "Affiliate Transaction") or extend, renew, waive or otherwise modify the
terms of any Affiliate Transaction entered into prior to the Issue 

                                       53

 
Date unless (i) such Affiliate Transaction is between or among the Company and
its Wholly-Owned Subsidiaries; (ii) such Affiliate Transaction is solely between
or among Wholly-Owned Subsidiaries of the Company; or (iii) the terms of such
Affiliate Transaction are fair and reasonable to the Company or such Restricted
Subsidiary, as the case may be, and the terms of such Affiliate Transaction are
at least as favorable as the terms which could be obtained by the Company or
such Restricted Subsidiary, as the case may be, in a comparable transaction made
on an arm's-length basis between unaffiliated parties; provided, however, that
                                                       --------  -------      
the Company and its Restricted Subsidiaries may renew any then existing
Affiliate Transaction through either a renewal option or upon expiration of an
arrangement on substantially similar terms to those in effect immediately
preceding such expiration.  In any Affiliate Transaction involving an amount or
having a value in excess of $1 million which is not permitted under clause (i)
or (ii) above, the Company must obtain a resolution of the Board of Directors
certifying that such Affiliate Transaction complies with clause (iii) above and
that such Affiliate Transaction has been approved by a majority of the
disinterested members of the Board of Directors.  In transactions with a value
in excess of $3 million which are not permitted under clause (i) or (ii) above,
the Company must obtain a written opinion as to the fairness from a financial
point of view of such a transaction from an independent investment banking firm
of national standing or real estate firm of national standing (as the case may
be).

          (b)  The limitations set forth in Section 4.11(a) will not apply to
(i) any Restricted Payment that is not prohibited by Section 4.9 hereof, (ii)
any trans action, approved by the Board of Directors of the Company in good
faith, with an officer, director, employee or consultant of the Company or of
any Subsidiary in his or her capacity as an officer, director, employee or
consultant entered into in the ordinary course of business, including
compensation, indemnity and employee benefit arrangements with any officer,
director, employee or consultant of the Company or of any Subsidiary, or (iii)
customary investment banking, underwriting, placement agent or financial advisor
fees paid in connection with services rendered to the Company or any Subsidiary.

Subsidiaries to, create, incur or otherwise cause or suffer to exist or become
effective any Liens of any kind (other than Permitted Liens) upon any property
or asset of the Company or any Restricted Subsidiary or any shares of stock or
debt of any Restricted Subsidiary which owns property or assets, now owned or
hereafter acquired, in any case which secures Indebtedness pari passu with or
                                                           ---- -----        
subordinated to the Notes unless (i) if such Lien secures Indebtedness which is
                                                                               
pari passu with the Notes, then the Notes are secured on an equal and ratable or
- ---- -----                                                                      
senior basis with the obligations so secured until such time as such obligation
is no longer secured by a Lien or (ii) if such Lien secures Indebtedness which
is subordinated to the Notes, any such Lien shall be subordinated to the Lien
granted to the Holders of the Notes in the same collateral to the same extent as
such subordinated Indebtedness is subordinated to the Notes.

Section 4.13.  Limitations on Investments.
               -------------------------- 

          The Company will not, and will not permit any of its Restricted
Subsidiaries to, make any Investment other than (i) a Permitted Investment or
(ii) an Investment that is made as a Restricted Payment in compliance with

Restricted Subsidiary existing as of the date of this Indenture, (ii) a
Restricted Subsidiary that is acquired or created after the date of this
Indenture, or (iii) an Unrestricted Subsidiary; provided, however, that each
                                                --------  -------           
Restricted Subsidiary organized under the laws of the United States or any State
thereof or the District of Columbia acquired or created pursuant to clause (ii)
shall, at the time it has either assets or shareholder's equity in excess of
$5,000, execute a guarantee, in the form attached as Exhibit C to this Indenture
and reasonably satisfactory in form and substance to the Trustee (and with such
docu-

                                       55

 
mentation relating thereto as the Trustee shall require, including, without
limitation, a supplement or amendment to this Indenture and an Opinion of
Counsel as to the enforceability of such Guarantee).

Section 4.15.  Limitation on Other Senior Subordinated Debt.
               -------------------------------------------- 

          The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, incur, contingently or otherwise, any
Indebtedness (other than the Notes and the Guarantees, as the case may be) that
is both (i) subordinate in right of payment to any Senior Indebtedness of the
Company or its Restricted Subsidiaries, as the case may be, and (ii) senior in
right of payment to the Notes and the Guarantees, as the case may be.  For
purposes of this Section 4.15, Indebtedness is deemed to be senior in right of
payment to the Notes and the Guarantees, as the case may be, if it is not
explicitly subordinate in right of payment to Senior Indebtedness at least to
the same extent as the Notes and the Guarantees, as the case may be, are
subordinate to Senior Indebtedness.

Section 4.16.  Limitation on Sale and Lease-Back Transactions.
               ---------------------------------------------- 

          The Company will not, and will not permit any Restricted Subsidiary
to, enter into any Sale and Lease-Back Transaction unless (i) the consideration
received in such Sale and Lease-Back Transaction is at least equal to the fair
market value of the property sold, as determined by a Board Resolution, and (ii)
the Company could incur the Attributable Indebtedness in respect of such Sale
and Lease-Back Transaction in compliance with Section 4.6.

Section 4.17.  Payments for Consent.
               -------------------- 

          Neither the Company nor any of its 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 agreed
to be paid to all Holders of the Notes which so consent, 

                                       56

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

Section 4.18.  Corporate Existence.
               ------------------- 

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

Section 4.19.  Change of Control.
               ----------------- 

          (a)  Within 30 days of the occurrence of a Change of Control, the
Company shall notify the Trustee in writing of such occurrence and shall make an
offer to purchase (the "Change of Control Offer") the outstanding Notes at a
purchase price equal to 101% of the principal amount thereof plus any accrued
and unpaid interest thereon to the Change of Control Payment Date (as
hereinafter defined) (such applicable purchase price being hereinafter referred
to as the "Change of Control Pur chase Price") in accordance with the procedures
set forth in this Section 4.19.

          If the Credit Facility is in effect, or any amounts are owing
thereunder or in respect thereof, at the time of the occurrence of a Change of
Control, prior to the mailing of the notice to Holders described in paragraph
(b) below, but in any event within 30 days following any Change of Control, the
Company covenants to (i) repay in full all obligations under or in respect of

                                       57

 
the Credit Facility or offer to repay in full all obligations under or in
respect of the Credit Facility and repay the obligations under or in respect of
the Credit Facility of each lender who has accepted such offer or (ii) obtain
the requisite consent under Credit Facility to permit the repurchase of the
Notes pursuant to this Section 4.19.  The Company must first comply with the
covenant described in the preceding sentence before it shall be required to
purchase Notes in the event of a Change of Control; provided that the Company's
                                                    ---------                  
failure to comply with the covenant described in the preceding sentence
constitutes an Event of Default described in clause (3) under Section 6.1 hereof
if not cured within 60 days after the notice required by such clause.

          (b)  Within 30 days of the occurrence of a Change of Control, the
Company also shall (i) cause a notice of the Change of Control Offer to be sent
at least once to the Dow Jones News Service or similar business news service in
the United States and (ii) send by first-class mail, postage prepaid, to the
Trustee and to each Holder of the Notes, at the address appearing in the
register maintained by the Registrar of the Notes, a notice stating:

          (i)  that the Change of Control Offer is being made pursuant to this
     Section 4.19 and that all Notes tendered will be accepted for payment, and
     otherwise subject to the terms and conditions set forth herein;

          (ii)  the Change of Control Purchase Price and the purchase date
     (which shall be a Business Day no earlier than 20 Business Days and no
     later than 60 Business Days from the date such notice is mailed (the
     "Change of Control Payment Date"));

          (iii)  that any Note not tendered will not be purchased and will
     continue to accrue interest;

          (iv)  that, unless the Company defaults in the payment of the Change
     of Control Purchase Price, any Notes accepted for payment pursuant to the
     Change of Control Offer shall cease to accrue interest after the Change of
     Control Payment Date;

                                       58

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

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

          (vii)  that Holders whose Notes are being purchased only in part will
     be issued new Notes equal in principal amount to the unpurchased portion of
     the Notes surrendered, provided that each Note purchased and each such new
                            --------                                           
     Note issued shall be in an original principal amount in denominations of
     $1,000 and integral multiples thereof;

          (viii)  any other procedures that a Holder must follow to accept a
     Change of Control Offer or effect withdrawal of such acceptance; and

          (ix)  the name and address of the Paying Agent.

          On the Change of Control Payment Date, the Company shall, to the
extent lawful, (i) accept for payment Notes or portions thereof or beneficial
interests under a Global Note properly tendered pursuant to the Change of
Control Offer, (ii) deposit with the Paying Agent money sufficient to pay the
Change of Control Purchase Price of all Notes or portions thereof or beneficial
interests so tendered and (iii) deliver or cause to be delivered to the Trustee
Notes so accepted together with an Officers' Certificate stating the Notes or
portions thereof tendered to the Company.  The Paying Agent shall promptly (1)
mail to each holder of Notes so ac-

                                       59

 
cepted and (2) cause to be credited to the respective accounts of the Holders
under a Global Note of beneficial interest so accepted payment in an amount
equal to the Change of Control Purchase Price for such Notes, and the Company
shall execute and issue, and the Trustee shall promptly authenticate and mail to
such holder, a new Note equal in principal amount to any unpurchased portion of
the Notes surrendered and shall issue a Global Note equal in principal amount to
any unpurchased portion of benefi cial interest so surrendered; provided that
                                                                --------
each such new Note shall be issued in an original principal amount in
denominations of $1,000 and integral multiples thereof.

          (c) (i)  If the Company or any Subsidiary thereof has issued any
outstanding (A) Indebtedness that is subordinated in right of payment to the
Notes or (B) Preferred Stock, and the Company or such Subsidiary is required to
make a change of control offer or to make a distribution with respect to such
subordinated Indebtedness or Preferred Stock in the event of a Change of
Control, the Company shall not consummate any such offer or distribution with
respect to such subordinated Indebtedness or Preferred Stock until such time as
the Company shall have paid the Change of Control Purchase Price in full to the
holders of Notes that have accepted the Company's Change of Control Offer and
shall otherwise have consummated the Change of Control Offer made to holders of
the Notes and (ii) the Company will not issue Indebtedness that is subordinated
in right of payment to the Notes or Preferred Stock with change of control
provisions requiring the payment of such Indebtedness or Preferred Stock prior
to the payment of the Notes in the event of a Change of Control under this
Indenture.

          In the event that a Change of Control occurs and the Holders of Notes
exercise their right to require the Company to purchase Notes, if such purchase
constitutes a "tender offer" for purposes of Rule 14e-1 under the Exchange Act
at that time, the Company will comply with the requirements of Rule 14e-1 as
then in effect with respect to such repurchase.

Section 4.20.  Maintenance of Office or Agency.
               ------------------------------- 

          The Company shall maintain an office or agency where Notes may be
surrendered for registration or trans-

                                       60

 
fer or exchange or for presentation for payment and where notices and demands to
or upon the Company in respect of the Notes and this Indenture may be served.
The Company shall give prompt written notice to the Trustee of the location, and
any change in the location, of such office or agency. If at any time the Company
shall fail to maintain any such required office or agency or shall fail to
furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the address of the Trustee as set
forth in Section 13.2.

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

          The Company hereby initially designates the Corporate Trust Office of
the Trustee set forth in Section 13.2 as such office of the Company.

                                       61

 
Section 4.21.  Maintenance of Properties and Insurance.
               --------------------------------------- 

          (a)  The Company shall cause all material properties used or useful
to the conduct of its business or the business of any of its Subsidiaries to be
maintained and kept in good condition, repair and working order (reasonable wear
and tear excepted) and supplied with all equipment deemed necessary in the good
faith judgment of the Officers of the Company and shall cause to be made all
necessary repairs, renewals, replacements, betterments and improvements thereof,
all as in its judgment may be necessary, so that the business carried on in
connection therewith may be properly and advantageously conducted at all times
unless the failure to so maintain such properties (together with all other such
failures) would not have a material adverse effect on the financial condition or
results of operations of the Company and its Subsidiaries, taken as a whole;
provided, however, that nothing in this Section 4.21 shall prevent the Company
- --------  -------                                                             
or any Subsidiary from discontinuing the operation or maintenance of any of such
properties, or disposing of any of them, if such discontinuance or disposal is
in the good faith judgment of the Board of Directors of the Company or the
Subsidiary concerned, as the case may be, desirable in the conduct of the
business of the Company or such Subsidiary, as the case may be, and is not
adverse in any material respect to the Holders.

          (b)  The Company shall provide or cause to be provided, for itself and
each of its Subsidiaries, insurance (including appropriate self-insurance)
against loss or damage of the kinds that, in the reasonable, good faith opinion
of the Company are adequate and appropriate for the conduct of the business of
the Company and such Subsidiaries in a prudent manner, with reputable insurers
or with the government of the United States of America or an agency or
instrumentality thereof, in such amounts, with such deductibles, and by such
methods as shall be customary, in the good faith judgment of the Company, for
corporations similarly situated in the industry, unless the failure to provide
such insurance (together with all other such failures) would not have a material
adverse effect on the financial condition or results of operations of the
Company and its Subsidiaries, taken as a 

                                       62

 
whole.

Section 6.1.   Events of Default.
               ----------------- 

          An "Event of Default" occurs if

          (1)  there is a default in the payment of any principal of, or
     premium, if any, on the Notes when the same becomes due and payable at
     maturity, upon acceleration, redemption or otherwise, whether or not such

     provisions of Article 11 hereof;

          (3)  the Company or any Guarantor defaults in the observance or

     then outstanding to the Company and the Trustee;

          (4)  there is a default in the payment at final maturity of principal
     in an aggregate amount of $3,000,000 or more with respect to any
     Indebtedness of the Company or any Restricted Subsidiary thereof which

     with the holders of such Indebtedness within 60 days after written notice,
     or the acceleration of any such Indebtedness aggregating $3,000,000 or more
     which acceleration shall not be rescinded or annulled within 20 days after
     written notice to the Company of such Default by the Trustee or to the
     Company and the Trustee by any Holder;

          (5)  a court of competent jurisdiction enters a final judgment or
     judgments which can no longer be appealed for the payment of money in
     excess of $3,000,000 (which are not paid or covered by third party
     insurance by financially sound insurers that have not disclaimed coverage)
     against the Company or any Restricted Subsidiary thereof and such judgment
     remains undischarged, for a period of 60 consecutive days during which a
     stay of enforcement of such judgment shall not be in effect;

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

               (A)  commences a voluntary case,

          Subsidiary,

          and, in each case, the order or decree remains unstayed and in effect

Federal or state law for the relief of debtors.  The term "Custodian" means any
receiver, trustee, assignee, liquidator or similar official under any Bankruptcy
Law.

          Subject to the provisions of Sections 7.1 and 7.2, the Trustee shall

Office by the Company or any other Person.

                                       66

 
Section 6.2.   Acceleration.
               ------------ 

          If an Event of Default (other than an Event of Default arising under
Section 6.1(6) or (7) with respect to the Company) occurs and is continuing, the
Trustee by notice to the Company, or the Holders of not less than 25% in
aggregate principal amount of the Notes then outstanding by written notice to
the Company and the Trustee, may declare to be immediately due and payable the
entire principal amount of all the Notes then outstanding plus premium, if any,
and accrued but unpaid interest to the date of acceleration and (i) such amounts
shall become immediately due and payable or (ii) if there are any amounts
outstanding under or in respect of the Credit Facility, such amounts shall
become due and payable upon the first to occur of an acceleration of amounts
outstanding under or in respect of the Credit Facility or five Business Days
after receipt by the Company and the Representative of notice of the
acceleration of the Notes; provided, however, that after such acceleration but
                           --------  -------
before a judgment or decree based on such acceleration is obtained by the
Trustee, the Holders of a majority in aggregate principal amount of the
outstanding Notes may rescind and annul such acceleration and its consequences
if all existing Events of Default, other than the nonpayment of accelerated
principal, premium, if any, or interest that has become due solely because of
the acceleration, have been cured or waived and if the rescission would not
conflict with any judgment or decree. No such rescission shall affect any
subsequent Default or impair any right consequent there to. In case an Event of
Default specified in Section 6.1 (6) or (7) with respect to the Company occurs,
the principal, premium, if any, and interest amount with respect to all of the
Notes shall be due and payable immediately without any declaration or other act
on the part of the Trustee or the Holders of the Notes.

Section 6.3.   Other Remedies.
               -------------- 

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

                                       67

 
the Notes or this Indenture and may take any necessary action requested of it as
Trustee to settle, compromise, adjust or otherwise conclude any proceedings to
which it is a party.

          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 Noteholder in exercising any right or remedy
accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default.  No remedy is
exclusive of any other remedy.  All available remedies are cumulative to the
extent permitted by law.

Section 6.4.   Waiver of Past Defaults and
               Events of Default.
               ---------------------------

          Subject to Sections 6.2, 6.7 and 8.2 hereof, the Holders of a majority
in principal amount of the Notes then outstanding have the right to waive any
existing Default or Event of Default or compliance with any provision of this
Indenture or the Notes.  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 Event of Default or impair any right
consequent thereto.

Section 6.5.   Control by Majority.
               ------------------- 

          The Holders of a majority in principal amount of the Notes then
outstanding may direct the time, method and place of conducting any proceeding
for any remedy available to the Trustee or exercising any trust or power
conferred on the Trustee by this Indenture.  The Trustee, however, may refuse to
follow any direction that conflicts with law or this Indenture or that the
Trustee determines may be unduly prejudicial to the rights of another Noteholder
not taking part in such direction, and the Trustee shall have the right to
decline to follow any such direction if the Trustee, being advised by counsel,
determines that the action so directed may not lawfully be taken or if the
Trustee in good faith shall, by a Trust Officer, determine that the proceedings
so directed may involve it in personal liability; provided that the 
                                                  --------                     

                                       68

 
Trustee may take any other action deemed proper by the Trustee which is not
inconsistent with such direction.

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

          Subject to Section 6.7 below, a Noteholder may not institute any
proceeding or pursue any remedy with respect to this Indenture or the Notes

          (5)  no direction inconsistent with such written request has been
     given to the Trustee during such 60 day period by the Holders of a majority
     in aggregate principal amount of the Notes then outstanding.

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

          Notwithstanding any other provision of this Indenture, the right of
any Holder of a Note to receive payment of principal of, or premium, if any, and
interest of the Note on or after the respective due dates expressed in the
Note, or to bring suit for the enforcement of any such payment on or after such
respective dates, is absolute and unconditional and shall not be impaired or

                                       69

 
affected without the consent of the Holder.

Section 6.8.   Collection Suit by Trustee.
               -------------------------- 

          If an Event of Default in payment of principal, premium or interest
specified in Section 6.1(1) or (2) hereof occurs and is continuing, the Trustee
may recover judgment in its own name and as trustee of an express trust against
the Company or the Guarantors (or any other obligor on the Notes) for the whole
amount of unpaid principal and accrued interest remaining unpaid, together with
interest on overdue principal and, to the extent that payment of such interest
is lawful, interest on overdue installments of interest, in each case at the
rate then borne by the Notes, and such further amounts 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, including all sums due and owing to the Trustee pursuant to Section
7.7.

Noteholders allowed in any judicial proceedings relative to the Company or the
Guarantors (or any other obligor upon the Notes), its creditors or its property
and shall be entitled and empowered to collect and receive any monies or other
property payable or deliverable on any such claims and to distribute the same
after deduction of its reasonable charges and expenses to the extent that any
such charges and expenses are not paid out of the estate in any such proceedings
and any custodian in any such judicial proceeding is hereby authorized by each
Noteholder 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
Noteholders, 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 7.7 hereof.

                                       70

 
          Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Noteholder any plan
or reorganization, arrangement, adjustment or composition affecting the Notes or
the rights of any Holder thereof, or to authorize the Trustee to vote in respect
of the claim of any Noteholder in any such proceedings.

Section 6.10.  Priorities.
               ---------- 

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

     FIRST:  to the Trustee for amounts due under Section 7.7 hereof;

     SECOND:  to Noteholders for amounts due and unpaid on the Notes for
principal, premium, if any, and interest as to each, ratably, without preference
or priority of any kind, according to the amounts due and payable on the Notes;

from any Guarantor, to such Guarantor.

          The Trustee may fix a record date and payment date for any payment to
Noteholders pursuant to this Section 6.10.  The Trustee shall give the Company
prior notice of any such record date and payment date; provided, however, that
                                                       ---------  -------      
the failure to give any such notice shall not affect the establishment of such
record date or payment date or any payment to Noteholders pursuant to this
Section 6.10.

Section 6.11.  Undertaking for Costs.
               --------------------- 

          In any suit for the enforcement of any right or remedy under this
Indenture or in any suit against the Trustee for any action taken or omitted by
it as Trustee, a court in its discretion may require the filing by any party
litigant in the suit of an undertaking to pay the costs of the suit, and the
court in its discretion may assess reasonable costs, including reasonable
attorneys' 

                                       71

 
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.

pursuant to Section 6.7 hereof or a suit by Holders of more than 10% in
principal amount of the Notes then outstanding.

Section 6.12.  Restoration of Rights and Remedies.
               ---------------------------------- 

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


                                  ARTICLE 7.

                                    TRUSTEE

Section 7.1.   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 their exercise as a
prudent man would exercise or use under the same circumstances in the conduct
of his own affairs.

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

          (1)  The Trustee need perform only those duties 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.

          (2)  In the absence of bad faith on its part, 

                                       72

 
     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 but, in the case of any such certificates or opinions which
     by any provision hereof are specifically required to be furnished to the
     Trustee, the Trustee shall be under a duty to examine the same to determine
     whether or not they conform to the requirements of this Indenture (but
     need not confirm or investigate the accuracy of mathematical calculations
     or other facts stated therein).

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

          (1)  This paragraph does not limit the effect of paragraph (b) of this
     Section 7.1.

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

          (3)  The Trustee shall not be liable with respect to any action it
     takes or omits to take in good faith in accordance with a direction
     received by it pursuant to Sections 6.2 and 6.5 hereof.

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

          (d)  Whether or not therein expressly so provided, paragraphs (a),
(b), (c), (e) and (f) of this Section 7.1 shall govern every provision of this
Indenture that in any way relates to the Trustee.

                                       73

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

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

Section 7.2.   Rights of Trustee.
               ----------------- 

          Subject to Section 7.1 hereof:

          (1)  The Trustee may rely on and shall be protected in acting or
     refraining from acting upon any document reasonably believed by it to be
     genuine and to have been signed or presented by the proper person.  The
     Trustee need not investigate any fact or matter stated in the document.

          (2)  Before the Trustee acts or refrains from acting, it may require
     an Officers' Certificate or an Opinion of Counsel, or both, which shall
     conform to the provisions of Section 13.5 hereof. The Trustee shall be
     protected and shall not be liable for any action it takes or omits to take
     in good faith in reliance on such certificate or opinion.

          (3)  The Trustee may act through agents and attorneys and shall not be
     responsible for the misconduct or negligence of any agent or attorney
     (other than the negligence or willful misconduct of an agent who is an
     employee of the Trustee) appointed by it with due care.

          (4)  The Trustee shall not be liable for any action it takes or omits
     to take in good faith which it reasonably believes to be authorized or
     within its rights or powers; provided that the Trustee's conduct does not
                                  --------                                    
     constitute negligence or bad faith.

          (5)  The Trustee may consult with counsel of its selection, and the
     advice or opinion of such 

                                       74

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

Section 7.3.   Individual Rights of Trustee.
               ---------------------------- 

          The Trustee in its individual or any other capacity may become the
owner or pledgee of Notes and may make loans to, accept deposits from, perform
services for or otherwise deal with the Company or any Guarantor, or any
Affiliates thereof, with the same rights it would have if it were not Trustee.
Any Agent may do the same with like rights.  The Trustee, however, shall be
subject to Sections 7.10 and 7.11 hereof.

Section 7.4.   Trustee's Disclaimer.
               -------------------- 

          The Trustee makes no representation as to the validity or adequacy of
this Indenture or the Notes, it shall not be accountable for the Company's use
of the proceeds from the sale of Notes or any money paid to the Company pursuant
to the terms of this Indenture and it shall not be responsible for any statement
in the Notes or any document used in connection with the sale of the Notes other
than its certificate of authentication.

Section 7.5.   Notice of Defaults.
               ------------------ 

          If a Default occurs and is continuing and if it is actually known to
the Trustee, the Trustee shall mail to each Noteholder notice of the Default
within 90 days after it occurs.  Except in the case of a Default in payment of
the principal of, or premium, if any, or interest on any Note, the Trustee may
withhold the notice if and so long as the board of directors of the Trustee, the
executive committee or any trust committee of such board and/or its Trust
Officers in good faith determine(s) that withholding the notice is in the
interests of the Noteholders.

Section 7.6.   Reports by Trustee to Holders.
               ----------------------------- 

          If required by TIA (S) 313(a), within 60 days after March 1 of any
year, commencing March 1, 1998, the 

                                       75

 
Trustee shall mail to each Noteholder a brief report dated as of such March 1
that complies with TIA (S) 313(a); provided that no such report need be
                                   --------
transmitted if no such events listed in TIA (S) 313(a) have occurred within 
such period. 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) and TIA
(S) 313(d).

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

Section 7.7.   Compensation and Indemnity.
               -------------------------- 

          The Company and the Guarantors shall pay to the Trustee from time to
time such reasonable compensation as shall be agreed in writing between the
Company and the Trustee for its services hereunder (which compensation shall not
be limited by any provision of law in regard to the compensation of a trustee of
an express trust).  The Company and the Guarantors shall reimburse the Trustee
upon request for all reasonable disbursements, expenses and advances incurred or
made by it in connection with its duties under this Indenture, including the
reasonable compensation, disbursements and expenses of the Trustee's agents and
counsel.

          The Company and the Guarantors shall indemnify each of the Trustee and
any predecessor Trustee for, and hold it harmless against, any and all loss,
damage, claim, liability, reasonable expense (including but not limited to
reasonable attorneys' fees and expenses) or taxes (other than taxes based on the
income of the Trustee) incurred by it in connection with the acceptance or
performance of its duties under this Indenture including the reasonable costs
and expenses of defending itself against any claim or liability in connection
with the exercise or performance of any of its powers or duties hereunder
(including, without limitation, settlement costs).  The Trustee shall notify the
Company and the Guarantors in writing promptly of any claim asserted against the
Trustee for which it may seek indemnity.  However, the failure by the Trustee to
so notify the 

                                       76

 
Company and the Guarantors shall not relieve the Company or the Guarantors of
their obligations hereunder.

          Notwithstanding the foregoing, the Company and the Guarantors need not
reimburse the Trustee for any expense or indemnify it against any loss or
liability incurred by the Trustee through its negligence or bad faith.  To
secure the payment obligations of the Company and the Guarantors in this Section
7.7, the Trustee shall have a lien prior to the Notes on all money or property
held or collected by the Trustee in its capacity as such, except such money or
property held in trust to pay principal of and interest on particular Notes.
The obligations of the Company and the Guarantors under this Section 7.7 to
compensate and indemnify the Trustee and each predecessor Trustee and to pay or
reimburse the Trustee and each predecessor Trustee for expenses, disbursements
and advances shall be joint and several liabilities of the Company and each of
the Guarantors and shall survive the satisfaction and discharge of this
Indenture, including the termination or rejection hereof in any bankruptcy
proceeding to the extent permitted by law.

          When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 6.1(6) or (7) hereof occurs, the expenses and the
compensation for the services are intended to constitute expenses of
administration under any Bankruptcy Law.

          For purposes of this Section 7.7, the term "Trustee" shall include any
trustee appointed pursuant to Article 9.

Section 7.8.   Replacement of Trustee.
               ---------------------- 

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

          (1)  the Trustee fails to comply with Section 7.10 

                                       77

 
     hereof;

          (2)  the Trustee is adjudged a bankrupt or an insolvent;

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

          (4)  the Trustee otherwise becomes incapable of acting.

          If the Trustee resigns or is removed or if a vacancy exists in the
office of Trustee for any reason, the Company shall promptly appoint a successor
Trustee.

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

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

          A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Immediately following
such delivery, the retiring Trustee shall, subject to its rights under Section
7.7 hereof, transfer all property held by it as Trustee to the successor
Trustee, the resignation or removal of the retiring Trustee shall become
effective, and the successor Trustee shall have all the rights, powers and
duties of the Trustee under this Indenture. A successor Trustee shall mail
notice of its succession to each Noteholder. Notwithstanding replacement of the
Trustee pursuant to this Section 7.8, the Company's obligations under Section
7.7 hereof shall continue for the benefit of the retiring Trustee.

Section 7.9.   Successor Trustee by Consolidation,
               Merger or Conversion.
               -------------------- 

          If the Trustee consolidates with, merges or 

                                       78

 
converts into, or transfers all or substantially all of its corporate trust
assets to, another corporation or national banking association, subject to
Section 7.10 hereof, the successor corporation or national banking association
without any further act shall be the successor Trustee.

Section 7.10.  Eligibility; Disqualification.
               ----------------------------- 

          This Indenture shall always have a Trustee who satisfies the
requirements of TIA (S) 310(a)(1) and (2) in every respect.  The Trustee shall
have a combined capital and surplus of at least $100,000,000 as set forth in its
most recent published annual report of condition.  The Trustee shall comply with
(S) TIA (S) 310(b), including the provision in (S) 310(b)(1); provided that
                                                              --------     
there shall be excluded from the operation of TIA (S) 310(b)(1) any indenture
or indentures under which other securities, or certificates of interest or
participation in other securities, of the Company or the Guarantors are
outstanding if the requirements for exclusion set forth in TIA (S) 310(b)(1) are
met.

Section 7.11.  Preferential Collection of
               Claims Against Company.
               ---------------------- 

          The Trustee shall comply with 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.

Section 7.12.      Paying Agents.
                    ------------- 

          The Company shall cause each Paying Agent other than the Trustee to
execute and deliver to it and the Trustee an instrument in which such agent
shall agree with the Trustee, subject to the provisions of this Section 7.12:

          (A)  that it will hold all sums held by it as agent for the payment of
     principal of, or premium, if any, or interest on, the Notes (whether such
     sums have been paid to it by the Company or by any obligor on the Notes)
     in trust for the benefit of Holders

                                       79

 
     of the Notes or the Trustee;

          (B)  that it will at any time during the continuance of any Event of
     Default, upon written request from the Trustee, deliver to the Trustee all
     sums so held in trust by it together with a full accounting thereof; and

          (C)  that it will give the Trustee written notice within three (3)
     Business Days of any failure of the Company (or by any obligor on the
     Notes) in the payment of any installment of the principal of, premium, if
     any, or interest on, the Notes when the same shall be due and payable.

Section 8.1.   Without Consent of Holders.
               -------------------------- 

          The Company and the Guarantors, if any, when authorized by a Board
Resolution of each of them, and the Trustee may modify, waive, amend, restate or

     any Noteholder; or

          (5)  to evidence and provide for the acceptance of appointment
     hereunder by a successor Trustee with respect to the Notes.

          The Trustee is hereby authorized to join with the Company and the
Guarantors, if any, in the execution 

                                       80

          (3)  reduce the principal of or premium on or change the stated
     maturity of any Note

          (4)  make any Note payable in money other than that stated in the Note
     or change the place of payment from New York, New York;

          (5)  change the amount or time of any payment required by the Notes or
     reduce the premium payable upon any redemption of the Notes in accordance
     with Section 3.7 hereof, or change the time before which no such redemption
     may be made;

                                       81

 
          (6)  waive a default in the payment of the principal of, or interest
     on, or redemption payment with respect to, any Note (including any
     obligation to make a Change of Control Offer or, after the Company's
     obligation to purchase Notes arises thereunder, an Excess Proceeds Offer
     or modify any of the provisions or definitions with respect to such
     offers);

          (7)  make any changes in Sections 6.4 or 6.7 hereof or this sentence
     of Section 8.2; or

          (8)  affect the ranking of the Notes in a manner adverse to the
     Holders.

          After a modification, amendment, supplement or waiver under this
Section 8.2 becomes effective, the Company shall mail to the Holders a notice
briefly describing the modification, amendment, supplement or waiver.  Any
failure of the Company to mail such notice, or any defect therein, shall not,
however, in any way impair or affect the validity of any such modification,
amendment, supplement or waiver.

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

Section 8.3.   Compliance with Trust Indenture Act.
               ----------------------------------- 

          Every amendment to or supplement of this Indenture or the Notes shall
comply with the TIA as then in effect.

                                       82

 
Section 8.4.   Revocation and Effect of Consents.
               --------------------------------- 

          Until a modification, amendment, supplement, waiver or other action
becomes effective, a consent to it by a Holder of a Note is a continuing consent
conclusive and binding upon such Holder and every subsequent Holder of the same
Note or portion thereof, and of any Note issued upon the transfer thereof or in
exchange therefor or in place thereof, even if notation of the consent is not
made on any such Note.  Any such Holder or subsequent Holder, however, may
revoke the consent as to his Note or portion of a Note, if the Trustee receives
the notice of revocation before the date the modification, amendment,
supplement, waiver or other action becomes effective.

          The Company may, but shall not be obligated to, fix a record date for
the purpose of determining the Holders entitled to consent to any modification,
amendment, supplement, or waiver.  If a record date is fixed, then,
notwithstanding the preceding paragraph, those Persons who were Holders at such
record date (or their duly designated proxies), and only such Persons, shall be
entitled to consent to such modification, amendment, supplement, or waiver or to
revoke any consent previously given, whether or not such Persons continue to be
Holders after such record date.  No such consent shall be valid or effective for
more than 90 days after such record date unless the consent of the requisite
number of Holders has been obtained.

          After a modification, amendment, supplement, waiver or other action
becomes effective, it shall bind every Noteholder, unless it makes a change
described in any of clauses (1) through (8) of Section 8.2 hereof.  In that
case, the modification, amendment, supplement, waiver or other action shall bind
each Holder of a Note who has consented to it and every subsequent Holder of a
Note or portion of a Note that evidences the same debt as the consenting
Holder's Note.

Section 8.5.   Notation on or Exchange of Notes.
               -------------------------------- 

          If a modification, amendment, supplement or waiver changes the terms
of a Note, the Trustee may request the Holder of the Note to deliver it to the

                                       83

 
Trustee.  In such case, the Trustee shall place an appropriate notation on the
Note about the changed terms and return it to the Holder. Alternatively, if the
Company or the Trustee so determines, the Company in exchange for the Note shall
issue and the Trustee shall authenticate and make available for delivery a new
security that reflects the changed terms. Failure to make the appropriate
notation or issue a new Note shall not affect the validity and effect of such
modification, amendment, supplement or waiver.

Section 8.6.   Trustee to Sign Amendments, etc.
               --------------------------------

          The Trustee shall sign any modification, amendment, supplement or
waiver authorized pursuant to this Article 8 if the modification, amendment,
supplement or waiver does not adversely affect the rights, duties, liabilities
or immunities of the Trustee.  If it does, the Trustee may, but need not, sign
it.  In signing or refusing to sign such modification, amendment, supplement or
waiver, the Trustee shall be entitled to receive and, subject to Section 7.1
hereof, shall be fully protected in relying upon an Officers' Certificate and an
Opinion of Counsel stating that such modification, amendment, supplement or
waiver is authorized or permitted by this Indenture and such supplemental
indenture constitutes the legal, valid and binding obligation of the Company and
the Guarantors enforceable against each of them in accordance with its terms
(subject to customary exceptions).  The Company or any Guarantor may not sign a
modification, amendment or supplement until the Board of Directors of the
Company or such Guarantor, as appropriate, approves it.


                                   ARTICLE 9.

                       DISCHARGE OF INDENTURE; DEFEASANCE

          The Company and the Guarantors, if any, may terminate their
obligations under the Notes, the Guarantees, if any, and this Indenture, except
the obligations referred to in the last paragraph of this Section 9.1, if 

                                       84

 
there shall have been cancelled by the Trustee or delivered to the Trustee for
cancellation all Notes thereto fore authenticated and delivered (other than any
Notes that are asserted to have been destroyed, lost or stolen and that shall
have been replaced as provided in Section 2.7 hereof) and the Company has paid
all sums payable by it hereunder or deposited all required sums with the
Trustee.

          After such delivery the Trustee upon request shall acknowledge in
writing the discharge of the Company's and the Guarantors' obligations under the
Notes, the Guarantees and this Indenture except for those surviving obligations
specified below.

          Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company in Sections 2.7, 7.7, 9.5, 9.6 and 9.8 hereof shall
survive.

Section 9.2.   Legal Defeasance.
               ---------------- 

          The Company may at its option, by Board Resolution, be discharged
from its obligations with respect to the Notes and the Guarantors, if any,
discharged from their obligations under the Guarantees, if any, on the date the
conditions set forth in Section 9.4 below are satisfied (hereinafter, "Legal
Defeasance"). For this purpose, such Legal Defeasance means that the Company
shall be deemed to have paid and discharged the entire indebtedness represented
by the Notes and to have satisfied all its other obligations under such Notes
and this Indenture insofar as such Notes are concerned (and the Trustee, at the
expense of the Company, shall, subject to Section 9.6 hereof, execute proper
instruments acknowledging the same), except for the following which shall
survive until otherwise terminated or discharged hereunder: (A) the rights of
Holders of outstanding Notes to receive solely from the trust funds described in
Section 9.4 hereof and as more fully set forth in such Section, payments in
respect of the principal of, premium, if any, and interest on such Notes when
such payments are due, (B) the Company's obligations with respect to such Notes
under Sections 2.3, 2.4, 2.5, 2.6, 2.7, 2.8 and 4.20 hereof, (C) the rights,
powers, trusts, duties, and immunities of the Trustee hereunder (including
claims of, or payments to, the Trustee under or pursuant to Section 

                                       85

 
7.7 hereof) and (D) this Article 9. Subject to compliance with this Article 9,
the Company may exercise its option under this Section 9.2 with respect to the
Notes notwithstanding the prior exercise of its option under Section 9.3 below
with respect to the Notes.

Section 9.3.   Covenant Defeasance.
               ------------------- 

          At the option of the Company, pursuant to a Board Resolution, the
Company and the Guarantors, if any, shall be released from their respective
obligations under Sections 4.2 through 4.19 hereof, inclusive, and clause (a)
(iii) of Section 5.1 hereof with respect to the outstanding Notes on and after
the date the conditions set forth in Section 9.4 hereof are satisfied
(hereinafter, "Covenant Defeasance") and the Notes shall thereafter be deemed to
not be outstanding for purposes of any direction, waiver, consent, declaration
or act of the Holders (and the consequences thereof) in connection with such
covenants but shall continue to be outstanding for all other purposes hereunder.
For this purpose, such Covenant Defeasance means that the Company and the
Guarantors, if any, may omit to comply with and shall have no liability in
respect of any term, condition or limitation set forth in any such specified
Section or portion thereof, whether directly or indirectly by reason of any
reference elsewhere herein to any such specified Section or portion thereof or
by reason of any reference in any such specified Section or portion thereof to
any other provision herein or in any other document, but the remainder of this
Indenture and the Notes shall be unaffected thereby.

                                       86

 
Section 9.4.   Conditions to Defeasance or Covenant

applicable to it) as funds in trust for the purpose of making the following
payments, specifically pledged as security for, and dedicated solely to, the
benefit of the Holders of the Notes, (A) money in an amount, or (B) U.S.
Government Obligations which through the scheduled payment of principal and
interest in respect thereof in accordance with their terms will provide, not 
later than the due date of any payment, money in an amount, or (C) a combination
thereof, sufficient, in the opinion of a nationally-recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee, to pay and discharge, and which shall be applied by
the Trustee (or other qualifying trustee) to pay and discharge, the principal
of, premium, if any, and accrued interest on the outstanding Notes at the
maturity date of such principal, premium, if any, or interest, or on dates for
payment and redemption of such principal, premium, if any, and interest

of the longest preference period under any Bankruptcy Law applicable to the
Company in respect of such deposit (it being understood that this condition
shall not be deemed satisfied until the expiration of such period);

     (3) such Legal Defeasance or Covenant Defeasance shall not result in a
breach or violation of, or consti-

                                       87

 
tute default under any other agreement or instrument to which the Company is a
party or by which it is bound;

     (4) the Company shall have delivered to the Trustee an Opinion of Counsel

neither the trust nor the Trustee will be required to register as an investment
company under the Investment Company Act of 1940, as amended;

     (5) in the case of an election under Section 9.2 above, the Company shall
have delivered to the Trustee an Opinion of Counsel stating that (i) the Company
has received from, or there has been published by, the Internal Revenue Service

Federal income tax law with the effect that, and such opinion shall confirm
that, the Holders of the outstanding Notes or persons in their positions will
not recognize income, gain or loss for Federal income tax purposes solely as a
result of such Legal Defeasance and will be subject to Federal income tax on the
same amounts, in the same manner, including as a result of prepayment, and at
the same times as would have been the case if such Legal Defeasance had not
occurred;

     (6) in the case of an election under Section 9.3 hereof, the Company shall
have delivered to the Trustee an Opinion of Counsel to the effect that the
Holders of the outstanding Notes will not recognize income, gain or loss for

     (8) the Company shall have delivered to the Trustee an Officers'
Certificate stating that the deposit under clause (1) was not made by the
Company with the intent of 

                                       88

 
defeating, hindering, delaying or defrauding any creditors of the Company or
others.

Section 9.5.   Deposited Money and U.S. Government Obligations to Be Held in
               Trust; Other
               Miscellaneous Provisions.
               -----------------------------------------

          All money and U.S. Government Obligations (including the proceeds
thereof) deposited with the Trustee pursuant to Section 9.4 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 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 accrued interest, but such money need not be
segregated from other funds except to the extent required by law.  The Trustee
shall be under no duty to invest such money or U.S. Government Obligations.

          The Company and the Guarantors shall pay and indemnify the Trustee
against any tax, fee or other charge imposed on or assessed against the U.S.
Government Obligations deposited pursuant to Section 9.4 hereof or the
principal, premium, if any, 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 9 to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon Company
Request any money or U.S. Government Obligations held by it as provided in
Section 9.4 hereof which, in the opinion of a nationally-recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee, are in excess of the amount thereof which would then
be required to be deposited to effect an equivalent Legal Defeasance or Covenant
Defeasance.

Section 9.6. Reinstatement.
             ------------- 

          If the Trustee or Paying Agent is unable to apply any money or U.S.

reason of 

                                       89

 
any legal proceeding or by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting
such application, the obligations of the Company and any Guarantor under this
Indenture, the Notes and the Guarantees, if any, shall be revived and reinstated
as though no deposit had occurred pursuant to this Article 9 until such time as
the Trustee or Paying Agent is permitted to apply all such money or U.S.
Government Obligations in accordance with Section 9.1 hereof; provided, however,
                                                              --------  ------- 
that if the Company or any Guarantors have made any payment of, principal of,
premium, if any, or accrued interest on any Notes because of the reinstatement
of their obligations, the Company or such Guarantors, as the case may be, shall
be subrogated to the rights of the Holders of such Notes to receive such payment
from the money or U.S. Government Obligations held by the Trustee or Paying
Agent.

Section 9.7. Moneys Held by Paying Agent.
             --------------------------- 

          In connection with the satisfaction and discharge of this Indenture,
all moneys then held by any Paying Agent under the provisions of this Indenture
shall, upon demand of the Company, be paid to the Trustee, or if sufficient
moneys have been deposited pursuant to Section 9.4 hereof, to the Company (or,
if such moneys had been deposited by any Guarantors, to such Guarantors), and
thereupon such Paying Agent shall be released from all further liability with
respect to such moneys.

Section 9.8. Moneys Held in Trust.
             -------------------- 

          Any moneys deposited with the Trustee or any Paying Agent or then held
by the Company or any Guarantors in trust for the payment of the principal of,
or premium, if any, or interest on any Note that are not applied but remain
unclaimed by the Holder of such Note for two years after the date upon which the
principal of, or premium, if any, or interest on such Note shall have
respectively become due and payable shall be paid to the Company or, if
appropriate, the Guarantors, upon Company Request, or if such moneys are then
held by the Company or any Guarantors in trust, such moneys shall be released
from such trust; and all liability of the Trustee or such Paying Agent with
respect to such trust money shall thereupon cease; provided, however, that the
                                                   --------  -------          
Trustee or 

                                       90

 
any such Paying Agent, before being required to make any such repayment, may, at
the expense of the Company and the Guarantors, if any, either mail to each
Noteholder affected, at the address shown in the register of the Notes
maintained by the Registrar pursuant to Section 2.3 hereof, or cause to be
published once a week for two successive weeks, in a newspaper published in the
English language, customarily published each Business Day and of general
circulation in The City of New York, New York, a notice that such money remains
unclaimed and that, after a date specified therein, which shall not be less than
30 days from the date of such mailing or publication, any unclaimed balance of
such moneys then remaining will be repaid to the Company. After payment to the
Company or the Guarantors, if any, or the release of any money held in trust by
the Company or any Guarantors, as the case may be, Noteholders entitled to the
money must look only to the Company and any Guarantors for payment as general
creditors unless applicable abandoned property law designates another person.

                                       91

 
                                  ARTICLE 10.

                              GUARANTEE OF NOTES

Section 10.1.  Guarantee.
               --------- 

          Subject to the provisions of this Article 10, each Guarantor, by
execution of the Guarantee, will jointly and severally unconditionally guarantee
to each Holder and to the Trustee, on behalf of the Holders, (i) the due and
punctual payment of the principal of, and premium, if any, and interest on each
Note, when and as the same shall become due and payable, whether at maturity,
by acceleration or otherwise, the due and punctual payment of interest on the
overdue principal of, and premium, if any, and interest on the Notes, to the
extent lawful, and the due and punctual performance of all other Obligations of
the Company to the Holders or the Trustee all in accordance with the terms of
such Note and this Indenture, and (ii) in the case of any extension of time of
payment or renewal of any Notes or any of such other Obligations, that the same
will be promptly paid in full when due or performed in accordance with the terms
of the extension or renewal, at stated maturity, by acceleration or otherwise.
Each Guarantor, by execution of the Guarantee, will agree that its obligations
thereunder and hereunder shall be absolute and unconditional, irrespective of,
and shall be unaffected by, any invalidity, irregularity or unenforceability of
any such Note or this Indenture, any failure to enforce the provisions of any
such Note or this Indenture, any waiver, modification or indulgence granted to
the Company with respect thereto by the Holder of such Note or the Trustee, or
any other circumstances which may otherwise constitute a legal or equitable
discharge of a surety or such Guarantor.

          Each Guarantor, by execution of the Guarantee, will waive diligence,
presentment, filing of claims with a court in the event of merger or bankruptcy
of the Company, any right to require a proceeding first against the Company,
protest or notice with respect to any such Note or the Indebtedness evidenced
thereby and all demands whatsoever, and will covenant that the Guarantee will
not be discharged as to any such Note except by 

                                       92

 
payment in full of the principal thereof, premium if any, and interest thereon
and as provided in Section 9.1 hereof. Each Guarantor, by execution of the
Guarantee, will further agree that, as between such Guarantor, on the one
hand, and the Holders and the Trustee, on the other hand, (i) the maturity of
the Obligations guaranteed by the Guarantee may be accelerated as provided in
Article 6 hereof for the purposes of the Guarantee, notwithstanding any stay,
injunction or other prohibition preventing such acceleration in respect of the
Obligations guaranteed thereby, and (ii) 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 each Guarantor for the purpose of the Guarantee. In addition,
without limiting the foregoing provisions, upon the effectiveness of an
acceleration under Article 6 hereof, the Trustee shall promptly make a demand
for payment on the Notes under the Guarantee provided for in this Article 10
and not discharged. Failure to make such demand shall not affect the validity or
enforceability of the Guarantee upon any Guarantor.

          A Guarantee shall not be valid or become obligatory for any purpose
with respect to a Note unless the certificate of authentication on such Note
shall have been signed by or on behalf of the Trustee.

Section 10.2.  Execution and Delivery of Guarantees.
               ------------------------------------ 

          A Guarantee shall be executed on behalf of a Guarantor by the manual
or facsimile signature of an Officer of such Guarantor.  A guarantee need not be
affixed to a Note, and the validity and enforceability of any Guarantee shall
not be affected by the fact that it is not so affixed.

          If an Officer of a Guarantor whose signature is on the Guarantee no
longer holds that office, such Guarantee shall be valid nevertheless.

Section 10.3.  Limitation of Guarantee.
               ----------------------- 

          The obligations of each Guarantor will be limited to the maximum
amount as will, after giving effect to all other contingent and fixed
liabilities of 

                                       93

 
such Guarantor (including, without limitation, any guarantees of Senior
Indebtedness) and after giving effect to any collections from or payments made
by or on behalf of any other Guarantor in respect of the obligations of such
other Guarantor under its Guarantee or pursuant to its contribution obligations
under this Indenture, result in the obligations of such Guarantor under the
Guarantee not constituting a fraudulent conveyance or fraudulent transfer under
Federal or state law. Each Guarantor that makes a payment or distribution under
a Guarantee shall be entitled to a contribution from each other Guarantor in a
pro rata amount based on the Adjusted Net Assets of each Subsidiary Guarantor.

Section 10.4.  Release of Guarantor.
               -------------------- 

          A Guarantor shall be released from all of its obligations under its
Guarantee if:

          (i) the Guarantor has sold all or substantially all of its assets or
     the Company and its Restricted Subsidiaries have sold all of the Capital
     Stock of the Guarantor owned by them, in each case in a transaction in
     compliance with Sections 4.10 and 5.1 hereof to the extent applicable; or

          (ii)  the Guarantor merges with or into or consolidates with, or
     transfers all or substantially all of its assets to, the Company or another
     Guarantor in a transaction in compliance with Section 5.1 hereof;

and in each such case, the Company has delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent herein provided for relating to such transactions have been complied
with.

Section 10.5.  Guarantee Obligations Subordinated to Guarantor Senior
               Indebtedness.
               ------------ 

          Each Guarantor, by execution of the Guarantee, will covenant and
agree, and each Holder of Notes, by its acceptance thereof, likewise covenants
and agrees, that to the extent and in the manner hereinafter set forth in this
Article 10, the Indebtedness represented by the 

                                       94

 
Guarantee and the payment of any Obligations pursuant to the Guarantee by such
Guarantor are hereby expressly made subordinate and subject in right of payment
as provided in this Article 10 to the prior indefeasible payment and
satisfaction in full in cash or, as acceptable to the holders of Guarantor
Senior Indebtedness of such Guarantor, in any other manner, of all existing and
future Guarantor Senior Indebtedness of such Guarantor.

          This Section 10.5 and the following Sections 10.6 through 10.11 shall
constitute a continuing offer to all Persons who, in reliance upon such
provisions, become holders of or continue to hold Guarantor Senior Indebtedness
of any Guarantor; and such provisions are made for the benefit of the holders of
Guarantor Senior Indebtedness of each Guarantor; and such holders are made
obligees hereunder and they or each of them may enforce such provisions.

Section 10.6.  Payment Over of Proceeds upon Dissolution, etc., of a Guarantor.
               --------------------------------------------------------------- 

          In the event of (a) any insolvency or bankruptcy case or proceeding,
or any receivership, liquidation, reorganization or other similar case or
proceeding in connection therewith, relative to any Guarantor or to its
creditors, as such, or to its assets, whether voluntary or involuntary, or (b)
any liquidation, dissolution or other winding-up of any Guarantor, whether
voluntary or involuntary and whether or not involving insolvency or bankruptcy
or (c) any general assignment for the benefit of creditors or any other
marshaling of assets or liabilities of any Guarantor, then and in any such

occurrence of a Payment Default, no payment or distribution of any assets or
securities of a Guarantor (or any Restricted Subsidiary or Subsidiary of such
Guarantor) of any kind or character (including, without limitation, cash,

reason of the payment of any other Indebtedness of such Guarantor being
subordinated to its Obligations on its Guarantee) may be made by or on behalf of
such Guarantor (or any Restricted Subsidiary or Subsidiary of such Guarantor),

                                       97

 
in respect of all or any portion of its Obligations on its Guarantee following
the delivery by the representative of the holders of Guarantor Senior
Indebtedness (the "Guarantor Representative") to the Trustee of written notice
of (i) the occurrence of a Payment Default on Designated Senior Indebtedness
which constitutes Guaran tor Senior Indebtedness or (ii) the occurrence of a 
Non-Payment Event of Default on Designated Senior Indebtedness which constitutes
Guarantor Senior Indebtedness and the acceleration of the maturity of such
Designated Senior Indebtedness in accordance with its terms, and in any such
event, such prohibition shall continue until such Payment Default is cured,
waived in writing or ceases to exist or such acceleration has been rescinded or
otherwise cured. At such time as the prohibition set forth in the preceding
sentence shall no longer be in effect, subject to the provisions of the
following paragraph (b), such Guarantor shall resume making any and all

          (b) Unless Section 10.6 hereof shall be applicable, upon the
occurrence of a Non-Payment Event of Default on Designated Senior Indebtedness
which constitutes Guarantor Senior Indebtedness of any Guarantor, no payment or

Event of Default, unless and until (subject to any blockage of payments that may
then be in effect under the preceding paragraph (a)) the earliest to occur of
the following events:  (x) more than 179 days shall 

                                       98

(y) such Non-Payment Event of Default shall have been cured or waived in writing

been paid in full in cash and the Trustee has been so notified either by the
Guarantor Representative or such Guarantor or (z) such Guarantee Payment
Blockage Period shall have been terminated by written notice to such Guarantor
or the Trustee from the Guarantor Representative, after which, in the case of
clause (x), (y) or (z), such Guarantor shall resume making any and all required

default with respect to Designated Senior Indebtedness which constitutes
Guarantor Senior Indebtedness (other than a Payment Default) which existed or
was continuing on the date of the commencement of any Guarantee Payment Blockage
Period initiated by the Guarantor Representative shall be, or be made, the
basis for the commencement of a second Guarantee Payment Blockage Period
initiated by the Guarantor Representative unless such event of default shall
have been cured or waived for a period of not less than 90 consecutive days. In
no event shall a Guarantee Payment Blockage Period extend beyond 179 days from
the date of the receipt by the Trustee of the notice referred to in this Section
10.7(b) or, in the event of a Non-Payment Event of Default which formed the
basis for a Payment Blockage Period under Section 11.3(b) hereof, 179 days from
the date of the receipt by the Trustee of the notice referred to Section 11.3(b)
(the "Initial Guarantee Blockage Period"). Any number of additional Guarantee
Payment Blockage Periods may be commenced during the Initial Guarantee Blockage
Period; provided, however, that no such additional Guarantee Payment Blockage
        --------  -------
Period shall extend beyond the Initial Guarantee Blockage Period. After the
expiration of the Initial Guarantee Blockage Period, no Guarantee Payment
Blockage Period may be commenced under this Section 10.7(b) and no Payment
Blockage Period may be commenced under Section 11.3(b) hereof until at least 180
consecutive days have elapsed from the last day of the Initial Guarantee
Blockage Period.

          (c) In the event that, notwithstanding the foregoing, the Trustee or
the Holder of any Note shall

have received any payment from a Guarantor prohibited by the foregoing
provisions of this Section 10.7, then and in such event such payment shall be
paid over and delivered forthwith to the Guarantor Representative initiating
the Guarantee Payment Blockage Period, in trust for distribution to the holders
of Guarantor Senior Indebtedness or, if no amounts are then due in respect of
Guarantor Senior Indebtedness, promptly returned to the Guarantor, or as a

to receive payments and distributions of cash, property and securities of such
Guarantor made on such Guarantor Senior Indebtedness until all amounts due to be
paid under the Guarantee shall be paid in full.  For the purposes of such

Indebtedness of any cash, property or securities to which Holders of the Notes
or the Trustee would be entitled except for the provisions of this Article 10,
and no payments over pursuant to the provisions of this Article 10 to holders of
Guarantor Senior Indebtedness by Holders of the Notes or the Trustee, shall, as
among each Guarantor, its creditors other than holders of Guarantor Senior
Indebtedness and the Holders of the Notes, be deemed to be a payment or
distribution by such Guarantor to or on account of such Guarantor Senior
Indebtedness.

          If any payment or distribution to which the Holders would otherwise
have been entitled but for the provisions of this Article 10 shall have been
applied, pursuant to the provisions of this Article 10, to the payment of all
amounts payable under Guarantor Senior Indebtedness, then and in such case, the
Holders shall be entitled to receive from the holders of such Guarantor Senior
Indebtedness at the time outstanding any payments or distributions received by
such holders of Guarantor Senior Indebtedness in excess of the amount sufficient
to indefeasibly pay all amounts payable under or in respect 

                                      100

               Solely to Define Relative Rights.
               ----------------------------------

          The subordination provisions of this Article 10 are and are intended

other hand. Nothing contained in this Article 10 or elsewhere in this Indenture
or in the Notes is intended to or shall (a) impair, as among each Guarantor,
its creditors other than holders of its Guarantor Senior Indebtedness and the
Holders of the Notes, the obligation of such Guarantor, which is absolute and
unconditional, to make payments to the Holders in respect of its Obligations on
its Guarantee in accordance with its terms; or (b) affect the relative rights
against such Guarantor of the Holders of the Notes and creditors of such
Guarantor other than the holders of the Guarantor Senior Indebtedness; or (c)
prevent the Trustee or the Holder of any Note from exercising all remedies
otherwise permitted by applicable law upon a Default or an Event of Default
under this Indenture, subject to the rights, if any, under this Article 10 of
the holders of Guarantor Senior Indebtedness (1) in any insolvency or bankruptcy
case or proceeding, or any receivership, liquidation, arrangement,
reorganization or other similar case or proceeding in connection therewith or
any liquidation, dissolution or other winding-up, or any assignment for the
benefit of creditors or other marshaling of assets and liabilities referred to
in Section 10.6 hereof, to receive, pursuant to and in accordance with such
Section, cash, property and securities otherwise payable or deliverable to the
Trustee or such Holder, or (2) under the conditions specified in Section 10.7
hereof, to prevent any payment prohibited by such Section or enforce their
rights pursuant to Section 10.7(c) hereof.

          The failure by any Guarantor to make a payment in respect of its
obligations on its Guarantee by reason of any provision of this Article 10 shall
not be construed as preventing the occurrence of a Default or an Event of
Default hereunder.

Indebtedness which may at any time be held by it, to the same extent as any
other holder of Guarantor Senior Indebtedness, and nothing in this Indenture
shall deprive the Trustee of any of its rights as such holder.  Nothing in this
Article 10 shall apply to claims of, or payments to, the Trustee under or
pursuant to Section 7.7 hereof.

holders of Senior Indebtedness by Holders of the Notes or the Trustee, shall, as

Company to or on account of the Senior Indebtedness.

amounts payable under the Senior Indebtedness of the Company, then and in such
case the Holders shall be entitled to receive from the holders of such Senior
Indebtedness at the time outstanding any payments or distributions received by

indefeasibly pay all amounts payable under or in respect of such Senior
Indebtedness in full in cash.

proceeding, or any receivership, liquidation, arrangement, reorganization or
other similar case or proceeding in connection therewith, or any liquidation,
dissolution or other winding-up, or any assignment for the benefit of creditors
or other marshaling of assets and liabilities referred to in Section 11.2
hereof, to receive, pursuant to and in accordance with such Section, cash,
property and securities otherwise payable or deliverable to the Trustee or such
Holder, or (2) under the conditions specified in Section 11.3, to prevent any
payment prohibited by such Section or enforce their rights pursuant to Section
11.3(c) hereof.

          The failure to make a payment on account of principal of, premium, if

shall not be construed as preventing the occurrence of a Default or an Event of
Default hereunder.

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

Trustee his attorney-in-fact for any and all such purposes, including, in the
event of any dissolution, winding-up, liquidation or reorganization of the
Company whether in bankruptcy, insolvency, receivership proceedings, or
otherwise, the timely filing of a claim for the unpaid balance of the
indebtedness of the Company owing to such Holder in the form required in such

                                      110

 
proceedings and the causing of such claim to be approved. If the Trustee does

or by any non-compliance by the Company with the terms, provisions and covenants
of this Indenture, regardless of any knowledge thereof any such holder may have
or be otherwise charged with.

          (b) Without limiting the generality of subsection (a) of this Section
11.8, the holders of Senior Indebtedness may, at any time and from time to time,
without the consent of or notice to the Trustee or the Holders of the Notes,
without incurring responsibility to the Holders of the Notes and without

obligations hereunder of the Holders of the Notes to the holders of Senior
Indebtedness, do any one or more of the following:  (1) change the manner, place

this Indenture, the Trustee shall not be charged with knowledge of the existence

from any trustee, fiduciary or agent therefor; and, prior to the receipt of any
such written notice, the Trustee, subject to the provisions of this Section
11.9, shall be entitled in all respects to assume that no such facts exist.

          (b) Subject to the provisions of Section 7.1 hereof, the Trustee shall
be entitled to rely on the delivery to it of a written notice to the Trustee and
the Company by a Person representing itself to be a holder of Senior

rely on such notice.  In the event that the Trustee determines in good faith
that further evidence is required with respect to the right of any Person as a
holder of Senior Indebtedness to participate in any payment or distribution
pursuant to this Article 11, the Trustee may request such Person to furnish
evidence to the reasonable satisfaction of the Trustee as to the amount of
Senior Indebtedness held by such Person, the extent to which such Person is
entitled to participate in such payment or distribution and any other facts
pertinent to the rights of such Person under this Article 11, and if such
evidence is not furnished, the Trustee may defer any payment to such Person

I.   INTEREST.

          Pierce Leahy Corp., a Pennsylvania corporation (the "Company"),
promises to pay interest on the principal amount of this Note semiannually on
January 15 and July 15 of each year (each an "Interest Payment Date"),
commencing on January 15, 1998, at the rate of 9% per annum.  Interest will be
computed on the basis of a 360-day year of twelve 30-day months.  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 the original issuance of the
Notes.

          The Company shall pay interest on overdue principal, and on overdue
premium, if any, and overdue interest, to the extent lawful, at the rate equal
to 1% per annum in excess of the rate borne by the Notes.

II.  METHOD OF PAYMENT.

          The Company will pay interest on this Note provided for in Paragraph I
above (except defaulted interest) to the person who is the registered Holder of
this Note at the close of business on the January 1 or July 1 preceding the
Interest Payment Date (whether or not such day is a Business Day).  The Holder
must surrender this Note to a Paying Agent to collect principal payments.  The
Company will pay principal, premium, if any, and interest in money of the United
States that at the time of payment is legal tender for payment of public and
private debts; provided, however, that the Company may pay principal, premium,
               --------  -------                                              
if any, and interest by check payable in such money.  It may mail an interest
check to the Holder's registered address.

III. PAYING AGENT AND REGISTRAR.

          Initially, The Bank of New York, a New York banking corporation (the
"Trustee"), will act as Paying 

                                      A-4

 
Agent and Registrar. The Company may change any Paying Agent or Registrar
without notice to the Holders of the Notes. Neither the Company nor any of its
Subsidiaries or Affiliates may act as Paying Agent but may act as registrar or
co-registrar.

IV.  INDENTURE; RESTRICTIVE COVENANTS.

          The Company issued this Note under an Indenture dated as of July 7,
1997 (the "Indenture") by and between the Company and the Trustee.  The terms of
this Note include those stated in the Indenture and those made part of the
Indenture by reference to the Trust Indenture Act of 1939 (15 U.S. Code (S)(S)
77aaa-77bbbb) as in effect on the date of the Indenture.  This Note is subject
to all such terms, and the Holder of this Note is referred to the Indenture and
said Trust Indenture Act for a statement of them.  All capitalized terms in
this Note, unless otherwise defined, have the meanings assigned to them by the
Indenture.

          The Notes are general unsecured obligations of the Company limited to
$120,000,000 aggregate principal amount.  The Indenture imposes certain
restrictions on, among other things, the incurrence of indebtedness, the
incurrence of liens and the issuance of preferred stock by the Company and its
subsidiaries, mergers and sale of assets, the payments of dividends on, or the
repurchase of, capital stock of the Company and its subsidiaries, certain other
restricted payments by the Company and it subsidiaries, certain transactions
with, and investments in, its affiliates, certain sale and lease-back
transactions and a provision regarding change-of-control transactions. The
restrictions are subject to a number of important qualifications and exceptions.

V.   SUBORDINATION.

          The Indebtedness represented by the Notes is, to the extent and in the
manner provided in the Indenture, subordinated in right of payment to the prior
indefeasible payment and satisfaction in full in cash of all existing and future
Senior Indebtedness as defined in the Indenture, and this Note is issued subject
to such provisions.  Each Holder of this Note, by accepting the same, (a) agrees
to and shall be bound by such provisions,


                                      A-5

 
(b) authorizes and directs the Trustee, on behalf of such Holder, to take
such action as may be necessary or appropriate to effectuate the subordination
as provided in the Indenture and (c) appoints the Trustee attorney-in-fact of
such Holder for such purpose; provided, however, that the Indebtedness evidenced
                               --------  -------
by this Note shall cease to be so subordinate and subject in right of payment
upon any defeasance of this Note referred to in Paragraph XVII below.

VI.  OPTIONAL REDEMPTION.

          The Company, at its option, may redeem the Notes, in whole or in part,
at any time on or after July 15, 2002 at the redemption prices set forth in
Section 3.7 of the Indenture, together, in each case, with accrued and unpaid
interest to the redemption date.

          In addition, the Company, at its option, may redeem Notes out of the
Net Proceeds of one or more Public Equity Offerings at the redemption price, in
the amount and under the terms set forth in the Indenture.

VII. NOTICE OF REDEMPTION.

          Notice of redemption will be mailed via first class mail at least 30
days but not more than 60 days prior to the redemption date to each Holder of
Notes to be redeemed at its registered address as it shall appear on the
register of the Notes maintained by the Registrar.  On and after any Redemption
Date, interest will cease to accrue on the Notes or portions thereof called for
redemption unless the Company shall fail to redeem any such Note.

VIII.     OFFERS TO PURCHASE.

          The Indenture requires that certain proceeds from Asset Sales be used,
subject to further limitations contained therein, to make an offer to purchase
certain amounts of Notes in accordance with the procedures set forth in the
Indenture.  The Company is also required to make an offer to purchase Notes upon
occurrence of a Change of Control in accordance with procedures set forth in the
Indenture.

                                      A-6

 
 IX.      DENOMINATIONS, TRANSFER, EXCHANGE.

          The Notes are in registered form without coupons in denominations of
$1,000 and integral multiples thereof.  A Holder may register the transfer or
exchange of Notes in accordance with the Indenture.  The Registrar may require a
Holder, among other things, to furnish appropriate endorsements and transfer
documents and to pay any taxes and fees required by law or permitted by the
Indenture.  The Registrar need not register the transfer of or exchange any Note
selected for redemption for a period of 15 days before the day of mailing of the
notice of redemption of any such Notes to be redeemed or any Note after it is
called for redemption in whole or in part, except the unredeemed portion of any
Note being redeemed in part.

X.   PERSONS DEEMED OWNERS.

          The registered Holder of this Note may be treated as the owner of it
for all purposes.

XI.  UNCLAIMED MONEY.

          If money for the payment of principal, premium or interest on any Note
remains unclaimed for two years, the Trustee or Paying Agent will pay the money
back to the Company at its request.  After that, Holders entitled to money must
look only to the Company for payment as general creditors unless an "abandoned
property" law designates another person.

XII. AMENDMENT, SUPPLEMENT AND WAIVER.

          Subject to certain exceptions, the Indenture or the Notes may be
modified, amended or supplemented by the Company, the Guarantors, if any, and
the Trustee with the consent of the Holders of at least a majority in principal
amount of the Notes then outstanding and any existing default or compliance with
any provision may be waived in a particular instance with the consent of the
Holders of a majority in principal amount of the Notes then outstanding.
Without the consent of Holders, the Company, the Guarantors, if any, and the
Trustee may amend the 

                                      A-7

 
Indenture or the Notes or supplement the Indenture for certain specified
purposes including providing for uncertificated Notes in addition to
certificated Notes, and curing any ambiguity, defect or inconsistency, or making
any other change that does not materially and adversely affect the rights of any
Holder.

XIII.     SUCCESSOR ENTITY.

          When a successor corporation assumes all the obligations of its
predecessor under the Notes and the Indenture and immediately before and
thereafter no Default exists and certain other conditions are satisfied, the
predecessor corporation will be released from those obligations.

XIV. DEFAULTS AND REMEDIES.

          Events of Default are set forth in the Indenture.  If an Event of
Default (other than an Event of Default pursuant to Section 6.1(6) or (7) of the
Indenture with respect to the Company) occurs and is continuing, the Trustee
by notice to the Company, or the Holders of not less than 25% in aggregate
principal amount of the Notes then outstanding by written notice to the Company
and the Trustee, may declare to be immediately due and payable the entire
principal amount of all the Notes then outstanding plus accrued but unpaid
interest to the date of acceleration and (i) such amounts shall become
immediately due and payable or (ii) if there are any amounts outstanding under
or in respect of the Credit Facility, such amounts shall become due and payable
upon the first to occur of an acceleration of amounts outstanding under or in
respect of the Credit Facility or five Business Days after receipt by the
Company and the Representative of notice of the acceleration of the Notes;
provided, however, that after such acceleration but before judgment or decree
- -----------------
based on such acceleration is obtained by the Trustee, the Holders of a
majority in aggregate principal amount of the outstanding Notes may rescind and
annul such acceleration and its consequences if all existing Events of Default,
other than the nonpayment of principal, premium or interest that has become due
solely because of the acceleration, have been cured or waived and if the
rescission would not conflict with any judgment or decree. No such rescission
shall affect any
                                      A-8

 
subsequent Default or impair any right consequent thereto.  In case
an Event of Default specified in Section 6.1(6) or (7) of the Indenture with
respect to the Company occurs, such, principal amount, together with premium,
if any, and interest with respect to all of the Notes, shall be due and payable
immediately without any declaration or other act on the part of the Trustee or
the Holders of the Notes.  The Trustee may withhold from Holders notice of any
continuing default (except a default in payment of principal, premium, if any,
or interest) if it determines that withholding notice is in their interests.

XV.  TRUSTEE DEALINGS WITH THE COMPANY.

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

XVI. NO RECOURSE AGAINST OTHERS.

          As more fully described in the Indenture, a director, officer,
employee, partner, affiliate, beneficiary or shareholder, as such, of the
Company or any Guarantor shall not have any liability for any obligations of
the Company or any Guarantor under the Notes or the Indenture or for any claim
based on, in respect or by reason of, such obligations or their creation.  The
Holder of this Note by accepting this Note waives and releases all such
liability.  The waiver and release are part of the consideration or the issuance
of this Note.

XVII.     DEFEASANCE AND COVENANT DEFEASANCE.

          The Indenture contains provisions for defeasance of the entire
indebtedness on this Note and for defeasance of certain covenants in the
Indenture upon compliance by the Company with certain conditions set forth in
the Indenture.

XVIII.    ABBREVIATIONS.

          Customary abbreviations may be used in the name
