any provision of this Indenture, the Company shall furnish to the Trustee an

counsel all such conditions precedent,



                                     20

if any, have been complied with, except that in the case of any such 
application or request as to which the furnishing of such documents is 
specifically required by any provision of this Indenture relating to such 
particular application or request, no additional certificate or opinion need 
be furnished.

               Every certificate with respect to compliance with a condition 
or covenant provided for in this Indenture (other than pursuant to Section 
1008(a)) shall include:

               (1) a statement that each individual signing such
            certificate or opinion has read such covenant or condition and the
            definitions herein relating thereto;

               (2) a brief statement as to the nature and scope of the
            examination or investigation upon which the statements or opinions
            contained in such certificate or opinion are based;

               (3) a statement that, in the opinion of each such
            individual, he or she has made such examination or investigation as
            is necessary to enable him to express an informed opinion as to
            whether or not such covenant or condition has been complied with;
            and

               (4) a statement as to whether, in the opinion of each such 
            individual, such condition or covenant has been complied with.

               SECTION 103.  FORM OF DOCUMENTS DELIVERED TO TRUSTEE.  In any 
case where several matters are required to be certified by, or covered by an 
opinion of, any specified Person, it is not necessary that all such matters 
be certified by, or covered by the opinion of, only one such Person, or that 
they be so certified or covered by only one document, but one such Person may 
certify or give an opinion with respect to some matters and one or more other 
such Persons as to other matters, and any such Person may certify or give an 
opinion as to such matters in one or several documents.

               Any certificate or opinion of an officer of the Company or the 
Guarantors may be based, insofar as it relates to legal matters, upon a 
certificate or opinion of, or representations by, counsel, unless such 
officer knows, or in the exercise of reasonable care should know, that the 
certificate or opinion or representations with respect to the matters upon 
which his certificate or opinion is based are erroneous. Any such certificate 
or Opinion of Counsel may be based, insofar as it relates to factual matters, 
upon a certificate or opinion of, or representations by, an officer or 
officers of the Company or the Guarantors stating that the information with 
respect to such factual matters is in the possession of the Company or the 
Guarantors, unless such counsel has actual knowledge that the certificate or 
opinion or representations with respect to such matters are erroneous.

               Where any Person is required to make, give or execute two or 
more applications, requests, consents, certificates, statements, opinions or 
other instruments under this Indenture, they may, but need not, be 
consolidated and form one instrument.

               SECTION 104.  ACTS OF HOLDERS.  (a)  Any request, demand, 
authorization, direction, notice, consent, waiver or other action provided by 
this Indenture to be given or taken by Holders may be embodied in and 
evidenced by one or more instruments of substantially



                                     21

similar tenor signed by such Holders in person or by agents duly appointed in 
writing; and, except as herein otherwise expressly provided, such action 
shall become effective when such instrument or instruments are delivered to 
the Trustee and, where it is hereby expressly required, to the Company. Such 
instrument or instruments (and the action embodied therein and evidenced 
thereby) are herein sometimes referred to as the "Act" of the Holders signing 
such instrument or instruments. Proof of execution of any such instrument or 
of a writing appointing any such agent shall be sufficient for any purpose of 
this Indenture and conclusive in favor of the Trustee and the Company, if 
made in the manner provided in this Section.

               (b) The fact and date of the execution by any Person of any 
such instrument or writing may be proved by the affidavit of a witness of 
such execution, by an attestation of another authorized officer or by a 
certificate of a notary public or other officer authorized by law to take 
acknowledgments of deeds, certifying that the individual signing such 
instrument or writing acknowledged to him the execution thereof. Where such 
execution is by a signer acting in a capacity other than his individual 
capacity, such certificate or affidavit shall also constitute sufficient 
proof of authority. The fact and date of the execution of any such instrument 
or writing, or the authority of the Person executing the same, may also be 
proved in any other manner which the Trustee deems sufficient.

               (c) The principal amount and serial numbers of Securities held 
by any Person, and the date of holding the same, shall be proved by the 
Security Register.

               (d) If the Company shall solicit from the Holders of 
Securities any request, demand, authorization, direction, notice, consent, 
waiver or other Act, the Company may, at its option, by or pursuant to Board 
Resolution, fix in advance a record date for the determination of Holders 
entitled to give such request, demand, authorization, direction, notice, 
consent, waiver or other Act, but the Company shall have no obligation to do 
so. Notwithstanding TIA Section 316(c), such record date shall be the record 
date specified in or pursuant to such Board Resolution, which shall be a date 
not earlier than the date 10 days prior to the first solicitation of Holders 
generally in connection therewith and not later than the date such 
solicitation is completed. If such a record date is fixed, such request, 
demand, authorization, direction, notice, consent, waiver or other Act may be 
given before or after such record date, but only the Holders of record at the 
close of business on such record date shall be deemed to be Holders for the 
purposes of determining whether Holders of the requisite proportion of 
Outstanding Securities have authorized or agreed or consented to such 
request, demand, authorization, direction, notice, consent, waiver or other 
Act, and for that purpose the Outstanding Securities shall be computed as of 
such record date; PROVIDED that no such authorization, agreement or consent 
by the Holders on such record date shall be deemed effective unless it shall 
become effective pursuant to the provisions of this Indenture not later than 
six months after the record date.

               (e) Any request, demand, authorization, direction, notice, 
consent, waiver or other Act of the Holder of any Security shall bind every 
future Holder of the same Security and the Holder of every Security issued 
upon the registration of transfer thereof or in exchange therefor or in lieu 
thereof in respect of anything done, omitted or suffered to be done by the 
Trustee or the Company in reliance thereon, whether or not notation of such 
action is made upon such Security.



                                     22

               SECTION 105.  NOTICES, ETC., TO TRUSTEE AND COMPANY.  Any 
request, demand, authorization, direction, notice, consent, waiver or Act of 
Holders or other document provided or permitted by this Indenture to be made 
upon, given or furnished to, or filed with,

               (1) the Trustee by any Holder or by the Company shall 
be sufficient for every purpose hereunder if made, given, furnished or filed 
in writing to or with the Trustee at its Corporate Trust Office, Attention: 
Corporate Trust Trustee Administration, or

               (2) the Company by the Trustee or by any Holder shall be 
sufficient for every purpose hereunder (unless otherwise herein expressly 
provided) if in writing and mailed, first-class postage prepaid, to the 
Company addressed to it at the address of its principal office specified in 
the first paragraph of this Indenture, or at any other address previously 
furnished in writing to the Trustee by the Company.

               SECTION 106.  NOTICE TO HOLDERS; WAIVER.  Where this Indenture 
provides for notice of any event to Holders by the Company, the Guarantors or 
the Trustee, such notice shall be sufficiently given (unless otherwise herein 
expressly provided) if in writing and mailed, first-class postage prepaid, to 
each Holder affected by such event, at his address as it appears in the 
Security Register, not later than the latest date, and not earlier than the 
earliest date, prescribed for the giving of such notice. In any case where 
notice to Holders is given by mail, neither the failure to mail such notice, 
nor any defect in any notice so mailed, to any particular Holder shall affect 
the sufficiency of such notice with respect to other Holders. Any notice 
mailed to a Holder in the manner herein prescribed shall be conclusively 
deemed to have been received by such Holder, whether or not such Holder 
actually receives such notice. Where this Indenture provides for notice in 
any manner, such notice may be waived in writing by the Person entitled to 
receive such notice, either before or after the event, and such waiver shall 
be the equivalent of such notice. Waivers of notice by Holders shall be filed 
with the Trustee, but such filing shall not be a condition precedent to the 
validity of any action taken in reliance upon such waiver.

               In case by reason of the suspension of or irregularities in 
regular mail service or by reason of any other cause, it shall be 
impracticable to mail notice of any event to Holders when such notice is 
required to be given pursuant to any provision of this Indenture, then any 
manner of giving such notice as shall be satisfactory to the Trustee shall be 
deemed to be a sufficient giving of such notice for every purpose hereunder.

               SECTION 107.  EFFECT OF HEADINGS AND TABLE OF CONTENTS.  The 
Article and Section headings herein and the Table of Contents are for 
convenience only and shall not affect the construction hereof.

               SECTION 108.  SUCCESSORS AND ASSIGNS.  All covenants and 
agreements in this Indenture by each of the Company and the Guarantors shall 
bind their respective successors and assigns, whether so expressed or not.

               SECTION 109.  SEPARABILITY CLAUSE.  In case any provision in 
this Indenture or in the Securities shall be invalid, illegal or 
unenforceable, the validity, legality and enforceability of the remaining 
provisions shall not in any way be affected or impaired thereby.



                                     23

               SECTION 110.  BENEFITS OF INDENTURE.  Nothing in this 
Indenture or in the Securities, express or implied, shall give to any Person, 
other than the parties hereto, any Paying Agent, any Securities Registrar and 
their successors hereunder, and the Holders any benefit or any legal or 
equitable right, remedy or claim under this Indenture.

               SECTION 111.  GOVERNING LAW.  This Indenture and the 
Securities shall be governed by and construed in accordance with the laws of 
the State of New York applicable to contracts to be performed entirely in 
that state.

               SECTION 112.  LEGAL HOLIDAYS.  In any case where any Interest 
Payment Date, Redemption Date, or Stated Maturity or Maturity of any Security 
shall not be a Business Day, then (notwithstanding any other provision of 
this Indenture or of the Securities) payment of interest or Additional 
Amounts, if any, or principal (and premium, if any) need not be made on such 
date, but may be made on the next succeeding Business Day with the same force 
and effect as if made on the Interest Payment Date, Redemption Date, or at 
the Stated Maturity or Maturity; PROVIDED that no additional interest shall 
accrue for the period from and after such Interest Payment Date, Redemption 
Date, Stated Maturity or Maturity, as the case may be, through such next 
succeeding Business Day.

               SECTION 113.  NO RECOURSE AGAINST OTHERS.  No director, 
officer, employee or stockholder, as such, of the Company or of a Guarantor 
shall have any liability for any obligations of thc Company or a Guarantor 
under the Securities or this Indenture or for any claim based on, in respect 
of or by reason of such obligations or their creation. By accepting a 
Security, each Holder shall waive and release all such liability. The waiver 
and release shall be part of the consideration for the issue of the 
Securities.

               SECTION 114.  MISCELLANEOUS.  The parties hereto may sign any 
number of copies of this Indenture.  Each signed copy shall be an original, 
but all of them together represent the same agreement. Notwithstanding any 
provision of this Indenture, Securities may only be redeemed or repurchased 
by the Company or any Guarantor in integral multiples of $1,000.

incurrence of Indebtedness by the Issuers, the aggregate principal amount of 
Additional Securities which may be authenticated and delivered under this 
Indenture is limited to $100.0 million, except in each case for Securities 
authenticated and delivered upon registration of transfer of, or in exchange

906, 1010, 1016 or 1108 (including Exchange Securities and Private Exchange 
Securities).

               The Initial Securities and the Additional Securities shall be 
known and designated as the "8/ /% Senior Subordinated Notes due 2008," and the 
Exchange Securities and the Private Exchange Securities shall be known and 
designated as the "8/ /% Senior Subordinated Notes due 2008," in each case, of 
the Company. The Stated Maturity of the Securities shall be April 15, 2008, 
and they shall bear interest at the rate of 8.375% per annum from April 15, 
1998, or from the most recent Interest Payment Date to which interest has 
been paid or duly provided for, payable on October 15, 1998 and semiannually 
thereafter on April 15 and October 15 in each year and at said Stated 
Maturity, until the principal thereof is paid or duly provided for.

               The principal of (and premium, if any, on), interest and 
Additional Amounts, if any, on the Securities shall be payable at the office 
or agency of the Company maintained for such purpose as provided in Section 
1002; PROVIDED, HOWEVER, that, at the option of the Company, interest may be 
paid by (i) check mailed to addresses of the Persons entitled thereto as such 
addresses shall appear on the Security Register or (ii) wire transfer to an 
account located in the United States maintained by the payee.

               The Securities shall be redeemable as provided in Article 
Eleven.

               SECTION 302.  DENOMINATIONS.  The Securities shall be issuable 
only in registered form without coupons and only in denominations of $1,000 
and any integral multiple thereof.

               SECTION 303.  EXECUTION, AUTHENTICATION, DELIVERY AND DATING.  
The Securities shall be executed on behalf of the Company by its Chairman, 
its President or a Vice President, and attested by its Secretary, an 
Assistant Secretary or any Vice President. The signature of any of these 
officers on the Securities may be manual or facsimile signatures of the 
present or any future such authorized officer and may be imprinted or 
otherwise reproduced on the Securities.

               Securities bearing the manual or facsimile Signatures of 
individuals who were, at the time such Securities were executed by such 
individuals, the proper officers of the Company shall bind the Company, 
notwithstanding that such individuals or any of them have ceased to hold such 
offices prior to the authentication and delivery of such Securities or did 
not hold such offices at the date of such Securities.



                                      29

               At any time and from time to time after the execution and 
delivery of this Indenture, the Company may deliver Securities executed by 
the Company to the Trustee for authentication, together with a Company Order 
for the authentication and delivery of such Securities, and the Trustee in 
accordance with such Company Order shall authenticate and deliver such 
Securities.

               Each Security shall be dated the date of its authentication.

               No Security shall be entitled to any benefit under this 
Indenture or be valid or obligatory for any purpose unless there appears on 
such Security a certificate of authentication substantially in the form 
provided for herein duly executed by the Trustee by manual signature of an 
authorized signatory, and such certificate upon any Security shall be 
conclusive evidence, and the only evidence, that such Security has been duly 
authenticated and delivered hereunder and is entitled to the benefits of this 
Indenture.

               In case the Company shall be consolidated or merged with or 
into any other Person or shall convey, transfer, lease or otherwise dispose 
of its properties and assets substantially as an entirety to any Person, and 
the successor Person resulting from such consolidation, or surviving such 
merger, or into which the Company shall have been merged, or the Person which 
shall have received a conveyance, transfer, lease or other disposition as 
aforesaid, shall have executed an indenture supplemental hereto with the 
Trustee pursuant to Article Eight, any of the Securities authenticated or 
delivered prior to such consolidation, merger, conveyance, transfer, lease or 
other disposition may, from time to time, at the request of the successor 
Person, be exchanged for other Securities executed in the name of the 
successor Person with such changes in phraseology and form as may be 
appropriate, but otherwise in substance of like tenor as the Securities 
surrendered for such exchange and of like principal amount; and the Trustee, 
upon Company Request of the successor Person, shall authenticate and deliver 
Securities as specified in such request for the purpose of such exchange. If 
Securities shall at any time be authenticated and delivered in any new name 
of a successor Person pursuant to this Section in exchange or substitution 
for or upon registration of transfer of any Securities, such successor 
Person, at the option of the Holders but without expense to them, shall 
provide for the exchange of all Securities at the time Outstanding for 
Securities authenticated and delivered in such new name.

               SECTION 304.  TEMPORARY SECURITIES.  Pending the preparation 
of definitive Securities, the Company may execute, and upon Company Order the 
Trustee shall authenticate and deliver, temporary Securities which are 
printed, lithographed, typewritten, mimeographed or otherwise produced, in 
any authorized denomination, substantially of the tenor of the definitive 
Securities in lieu of which they are issued and with such appropriate 
insertions, omissions, substitutions and other variations as the officers 
executing such Securities may determine, as conclusively evidenced by their 
execution of such Securities.

               If temporary Securities are issued, the Company will cause 
definitive Securities to be prepared without unreasonable delay.  After the 
preparation of definitive Securities, the temporary Securities shall be 
exchangeable for definitive Securities upon surrender of the temporary 
Securities at the office or agency of the Company designated for such purpose 
pursuant to Section 1002, without charge to the Holder. Upon surrender for 
cancellation of any 



                                      30

one or more temporary Securities, the Company shall execute and the Trustee 
shall authenticate and deliver in exchange therefor a like principal amount 
of definitive Securities of authorized denominations. Until so exchanged, the 
temporary Securities shall in all respects be entitled to the same benefits 
under this Indenture as definitive Securities.

               SECTION 305.  REGISTRATION, REGISTRATION OF TRANSFER AND 
EXCHANGE.  The Company shall cause to be kept at the Corporate Trust Office 
of the Trustee a register (the register maintained in such office and in any 
other office or agency designated pursuant to Section 1002 being herein 
sometimes referred to as the "SECURITY REGISTER") in which, subject to such 
reasonable regulations as it may prescribe, the Company shall provide for the 
registration of Securities and of transfers of Securities. The Security 
Register shall be in written form or any other form capable of being 
converted into written form within a reasonable time. At all reasonable 
times, the Security Register shall be open to inspection by the Trustee. The 
Trustee is hereby initially appointed as security registrar (the "REGISTRAR" 
or "SECURITY REGISTRAR") for the purpose of registering Securities and 
transfers of Securities as herein provided.

               Upon surrender for registration of transfer of any Security at 
the office or agency of the Company designated pursuant to Section 1002, the 
Company shall execute, and the Trustee shall authenticate and deliver, in the 
name of the designated transferee or transferees, one or more new Securities 
of any authorized denomination or denominations of a like aggregate principal 
amount.

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

               At the option of the Holder, Securities may be exchanged for 
other Securities of any authorized denomination and of a like aggregate 
principal amount, upon surrender of the Securities to be exchanged at such 
office or agency. Whenever any Securities are so surrendered for exchange 
(including an exchange of Initial Securities or Additional Securities for 
Exchange Securities or Private Exchange Securities), the Company shall 
execute, the Guarantors shall endorse and the Trustee shall authenticate and 
deliver, the Securities which the Holder making the exchange is entitled to 
receive; PROVIDED that no exchange of Initial Securities or Additional 
Securities for Exchange Securities shall occur until the Exchange Offer 
Registration Statement or another applicable registration statement shall 
have been declared effective by the Commission and the Initial Securities or 
Additional Securities to be exchanged for Exchange Securities or Private 
Exchange Securities shall be cancelled by the Trustee.

               All Securities issued upon any registration of transfer or 
exchange of Securities shall be the valid obligations of the Company and the 
Guarantors, evidencing the same debt, and entitled to the same benefits under 
this Indenture, as the Securities surrendered upon such registration of 
transfer or exchange.

               Every Security presented or surrendered for registration of 
transfer or for exchange shall (unless not required by the Company or the 
Security Registrar) be duly endorsed,


                                      31

or be accompanied by a written instrument of transfer, in form satisfactory 
to the Company and the Security Registrar, duly executed by the Holder 
thereof or his attorney duly authorized in writing.

               No service charge shall be made for any registration of 
transfer or exchange or redemption of Securities, but the Company may require 
payment of a sum sufficient to cover any tax or other governmental charge 
that may be imposed in connection with any registration of transfer or 
exchange of Securities, other than exchanges pursuant to Section 304, 906, 
1010, 1016 or 1108 not involving any transfer.

               The Company shall not be required (i) to issue, register the 
transfer of or exchange any Security during a period beginning at the opening 
of business 15 days before the selection of Securities to be redeemed under 
Section 1104 and ending at the close of business on the day of mailing of the 
relevant notice of redemption, or (ii) to register the transfer of or 
exchange any Security so selected for redemption in whole or in part, except 
the unredeemed portion of any Security being redeemed in part.

               SECTION 306.  BOOK-ENTRY PROVISIONS FOR GLOBAL SECURITIES.  
(a)  Each Global Security initially shall (i) be registered in the name of 
the Depositary for such global Security or the nominee of such Depositary, 
(ii) be delivered to the Trustee as custodian for such Depositary and (iii) 
bear legends as set forth in Section 202.

               Subject to Section 306(f), members of, or participants in, the 
Depositary ("AGENT MEMBERS") shall have no rights under this Indenture with 
respect to any Global Security held on their behalf by the Depositary, or the 
Trustee as its custodian, or under such Global Security, and the Depositary 
may be treated by the Company, the Guarantors, the Trustee and any agent of 
the Company, the Guarantors or the Trustee as the absolute owner of such 
Global Security for all purposes whatsoever. Notwithstanding the foregoing, 
nothing herein shall prevent the Company, the Guarantors the Trustee or any 
agent of the Company, the Guarantors or the Trustee, from giving effect to 
any written certification, proxy or other authorization furnished by the 
Depositary or shall impair, as between the Depositary and its Agent Members, 
the operation of customary practices governing the exercise of the rights of 
a holder of any Security.

               (b) Transfers of a Global Security shall be limited to 
transfers of such Global Security in whole, but not in part, to the 
Depositary, its successors or their respective nominees. Interests of 
beneficial owners in a Global Security may be transferred in accordance with 
the rules and procedures of the Depositary and the provisions of Section 307. 
Beneficial owners may obtain Certificated Securities in exchange for their 
beneficial interests in a Global Security upon request in accordance with the 
Depositary's and the Security Registrar's procedures. In addition, 
Certificated Securities shall be transferred to all beneficial owners in 
exchange for their beneficial interests in a Global Security if (i) the 
Depositary notifies the Company that it is unwilling or unable to continue as 
Depositary for such Global Security and a successor depositary is not 
appointed by the Company within 90 days of such notice, (ii) the Company 
executes and delivers to the Trustee and Registrar an Officers' Certificate 
stating that such Global Security shall be so exchangeable or (iii) an Event 
of Default has occurred and is continuing and the Registrar has received a 
request from the Depositary.


                                      32

               (c) In connection with any transfer of a portion of the 
beneficial interest in a Global Security to beneficial owners who are 
required to hold Certificated Securities pursuant to subsection (b) of this 
Section, the Registrar shall reflect on its books and records the date and a 
decrease in the principal amount of such Global Security in an amount equal 
to the principal amount of the beneficial interest in such Global Security to 
be transferred, and the Company shall execute, and the Trustee shall 
authenticate and deliver, one or more Certificated Securities of like tenor 
and amount.

               (d) In connection with the transfer of an entire Global 
Security to beneficial owners who are required to hold Certificated 
Securities pursuant to the fourth sentence of paragraph (b) of this Section, 
such Global Security shall 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 Depositary in exchange 
for its beneficial interest in such Global Security, an equal aggregate 
principal amount of Certificated Securities of authorized denominations.

               (e) Any Certificated Security delivered in exchange for an 
interest in a Global Security pursuant to paragraph (c) or paragraph (d) of 
this Section shall, except as otherwise provided by paragraph (c) of Section 
307, bear the applicable legends regarding transfer restrictions applicable 
to the Certificated Security set forth in Section 202.

               (f) The registered holder of a Global Security may grant 
proxies and otherwise authorize any person, including Agent Members and 
persons that may hold interests through Agent Members, to take any action 
which a Holder is entitled to take under this Indenture or the Securities, 
which proxies or authorizations shall be effective notwithstanding the second 
paragraph of Section 306(a).

               SECTION 307.  SPECIAL TRANSFER PROVISIONS.  (a) The following 
provisions shall apply with respect to any proposed transfer of a Rule 144A

               (c) PRIVATE PLACEMENT LEGEND.  Upon the transfer, exchange or 
replacement of Securities not bearing the Private Placement Legend, the 
Registrar shall deliver Securities that do not bear the Private Placement 
Legend. Upon the transfer, exchange or replacement of Securities bearing the 
Private Placement Legend, the Registrar shall deliver only Securities that 
bear the Private Placement Legend unless there is delivered to the Registrar 
an Opinion of Counsel reasonably satisfactory to the Company and the Trustee 
to the effect that neither such legend nor the related restrictions on 
transfer are required in order to maintain compliance with the provisions of 
the Securities Act.

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

               (e) If requested, the Company shall deliver to the Trustee an 
Officer's Certificate setting forth the dates on which the Restricted Period 
terminates.

               The Registrar shall retain copies of all letters, notices and 
other written communications received pursuant to Section 306 or this Section 
307. The Company shall have the right to inspect and make copies of all such 
letters, notices or other written communications at any reasonable time upon 
the giving of reasonable written notice to the Registrar.

               (f) NO OBLIGATION OF THE TRUSTEE. (i) The Trustee shall have 
no responsibility or obligation to any beneficial owner of a Global Security, 
a member of, or a participant in the Depositary or other Person with respect 
to any ownership interest in the Securities, with respect to the accuracy of 
the records of the Depositary or its nominee or of any participant or member 
thereof or with respect to the delivery to any participant, member, 
beneficial owner or other Person (other than the Depositary) of any notice 
(including any notice of redemption) or the payment of any amount, under or 
with respect to such Securities. All notices and communications to be given 
to the Holders and all payments to be made to Holders under the Securities 
shall be given or made only to the registered Holders (which shall be the 
Depositary or its nominee in the case of a Global Security). The rights of 
beneficial owners in any Global Security in global form shall be exercised 
only through the Depositary subject to the applicable rules and procedures of 
the Depositary. The Trustee may conclusively rely and shall be fully 
protected and indemnified pursuant to Section 606 in relying upon information 
furnished by the Depositary with respect to any beneficial owners, its 
members and participants.

                     (ii) The Trustee shall have no obligation or duty to

any transfer of any interest in any Security (including without limitation 
any transfers between or among Depositary participants, members or beneficial 
owners in any Global Security) other than to require delivery of such 
certificates and other documentation of evidence as are expressly required 
by, and to do so if and when expressly required by, the terms of this 
Indenture, and to examine the same to determine substantial compliance as to 
form with the express requirements hereof.


                                      35

                     (iii) Each Holder of a Security agrees to indemnify the 
Company and the Trustee against any liability that may result from the 
transfer, exchange or assignment of such Holder's Security in violation of 
any provision of this Indenture and/or applicable United States federal or 
state securities law.

               SECTION 308.  MUTILATED, DESTROYED, LOST AND STOLEN 
SECURITIES.  If (i) any mutilated Security is surrendered to the Trustee, or 
(ii) the Company and the Trustee receive evidence to their satisfaction of 
the destruction, loss or theft of any Security, and there is delivered to the 
Company and the Trustee (at the expense of the Holder) such security or 
indemnity as may be required by them to save each of them harmless, then, in 
the absence of notice to the Company or the Trustee that such Security has 
been acquired by a bona fide purchaser, the Company shall execute and upon 
Company Order the Trustee shall authenticate and deliver, in exchange for any 
such mutilated Security or in lieu of any such destroyed, lost or stolen 
Security, a new Security of like tenor and principal amount, bearing a number 
not contemporaneously outstanding.

               In case any such mutilated, destroyed, lost or stolen Security 
has become or is about to become due and payable, the Company in its 
discretion may, instead of issuing a new Security, pay such Security.

               Upon the issuance of any new Security under this Section, the 
Company may require the payment by the Holder of such mutilated, destroyed, 
lost or stolen Security of a sum sufficient to cover any tax or other 
governmental charge that may be imposed in relation thereto and any other 
expenses (including the fees and expenses of the Trustee) connected therewith.

               Every new Security issued pursuant to this Section in lieu of 
any destroyed, lost or stolen Security shall constitute an original 
additional contractual obligation of the Company and any Guarantor, whether 
or not the destroyed, lost or stolen Security shall be at any time 
enforceable by anyone, and shall be entitled to all benefits of this 
Indenture equally and proportionately with any and all other Securities duly 
issued hereunder.

               The provisions of this Section are exclusive and shall 
preclude (to the extent lawful) all other rights and remedies with respect to 
the replacement or payment of mutilated, destroyed, lost or stolen Securities.

               SECTION 309.  PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.  
Interest on any Security which is payable, and is punctually paid or duly 
provided for, on any Interest Payment Date shall be paid to the Person in 
whose name such Security is registered at the close of business on the 
Regular Record Date immediately prior to such Interest Payment Date at the 
office or agency of the Company maintained for such purpose pursuant to 
Section 1002; PROVIDED, HOWEVER, that each installment of interest may at the 
Company's option be paid by (i) mailing a check for such interest, payable to 
or upon the written order of the Person entitled thereto pursuant to Section 
310, to the address of such Person as it appears in the Security Register or 
(ii) wire transfer to an account located in the United States maintained by 
the payee.

               Any interest on any Security which is payable, but is not 
punctually paid or duly provided for, on any interest Payment Date shall 
forthwith cease to be payable to the Holder on


                                      36

the Regular Record Date by virtue of having been such Holder, and such 
defaulted interest and (to the extent lawful) interest on such defaulted 
interest at the rate borne by the Securities (such defaulted interest and 
interest thereon herein collectively called "DEFAULTED INTEREST") may be paid 
by the Company, at its election in each case, as provided in clause (1) or 
(2) below:

               (1)   The Company may elect to make payment of any Defaulted 
Interest to the Persons in whose names the Securities are registered at the 
close of business on a Special Record Date for the payment of such Defaulted 
Interest, which shall be fixed in the following manner. The Company shall 
notify the Trustee in writing of the amount of Defaulted Interest proposed to 
be paid on each Security and the date of the proposed payment, and at the 
same time the Company shall deposit with the Trustee an amount of money equal 
to the aggregate amount proposed to be paid in respect of such Defaulted 
Interest or shall make arrangements satisfactory to the Trustee for such 
deposit prior to the date of the proposed payment, such money when deposited 
to be held in trust for the benefit of the Persons entitled to such Defaulted 
Interest as in this clause provided. Thereupon the Trustee shall fix a 
Special Record Date for the payment of such Defaulted Interest which shall be 
not more than 30 days and not less than 10 days prior to the date of the 
proposed payment and not less than 10 days after the receipt by the Trustee 
of the notice of the proposed payment. The Trustee shall promptly notify the 
Company of such Special Record Date, and in the name and at the expense of 
the Company, shall cause notice of the proposed payment of such Defaulted 
Interest and the Special Record Date therefor to be given in the manner 
provided for in Section 106, not less than 10 days prior to such Special 
Record Date. Notice of the proposed payment of such Defaulted Interest and 
the Special Record Date therefor having been so given, such Defaulted 
Interest shall be paid to the Persons in whose names the Securities (or their 
respective Predecessor Securities) are registered at the close of business on 
such Special Record Date and shall no longer be payable pursuant to the 
following clause (2).

               (2)     The Company may make payment of any Defaulted Interest 
in any other lawful manner not inconsistent with the requirements of any 
securities exchange on which the Securities may be listed, and upon such 
notice as may be required by such exchange, if, after notice given by the 
Company to the Trustee of the proposed payment pursuant to this clause, such 
manner of payment shall not be deemed impracticable by the Trustee.

               Subject to the foregoing provisions of this Section, each 
Security delivered under this Indenture upon registration of transfer of or 
in exchange for or in lieu of any other Security shall carry the rights to 
interest accrued and unpaid, and to accrue, which were carried by such other 
Security.

               SECTION 310.  PERSONS DEEMED OWNERS.  Prior to the due 
presentment of a Security for registration of transfer, the Company, the 
Trustee and any agent of the Company or the Trustee may treat the Person in 
whose name such Security is registered as the owner of such Security for the 
purpose of receiving payment of principal of (and premium, if any, on), 
interest and Additional Amounts, if any, on such Security (subject to 
Sections 305 and 309) and for all other purposes whatsoever, whether or nor 
such Security be overdue, and none of the Company, the Trustee or any agent 
of the Company or the Trustee shall be affected by notice to the contrary.

               SECTION 311.  CANCELLATION.  All Securities surrendered for 
payment, redemption, registration of transfer or exchange shall, if 
surrendered to any Person other than the Trustee, be delivered to the Trustee 
and shall be promptly cancelled by it. The Company may at any time deliver to 
the Trustee for cancellation any Securities previously authenticated and 
delivered hereunder which the Company may have acquired in any manner 
whatsoever, and may deliver to the Trustee (or to any other Person for 
delivery to the Trustee) for cancellation any Securities previously 
authenticated hereunder which the Company has not issued and sold, and all 
Securities so delivered shall be promptly cancelled by the Trustee. If the 
Company shall so acquire any of the Securities, however, such acquisition 
shall not operate as a redemption or satisfaction of the Indebtedness 
represented by such Securities unless and until the same are surrendered to 
the Trustee for cancellation. No Securities shall be authenticated in lieu of 
or in exchange for any Securities cancelled as provided in this Section, 
except as expressly permitted by this Indenture. All cancelled Securities 
held by the Trustee shall be returned to the Company.

               SECTION 312.  COMPUTATION OF INTEREST.  Interest on the 
Securities shall be computed on the basis of a 360 day year of twelve 30-day 
months.

               SECTION 313.  CUSIP NUMBERS.  The Company in issuing the 
Securities may use "CUSIP" or "CINS" numbers (if then generally in use) and, 
if so, the Trustee shall use "CUSIP" or "CINS" numbers, as the case may be, 
in notices of redemption as a convenience to Holders; PROVIDED that any such 
notice may state that no representation is made as to the correctness of such 
numbers either as printed on the Securities or as contained in any notice of 
a redemption and that reliance may be placed only on the other identification 
numbers printed on the Securities, and any such redemption shall not be 
affected by any defect in or omission of such numbers. The Company will 
promptly notify the Trustee of any change in the "CUSIP" or "CINS" numbers.

                                 ARTICLE FOUR

               SECTION 401.  SATISFACTION AND DISCHARGE OF INDENTURE.  This 
Indenture will be discharged and shall cease to be of further effect (except 
as to surviving rights of registration of transfer or exchange of the 
Securities, as expressly provided for herein) as to all Outstanding 
Securities and the Trustee, at the expense of the Company, shall execute 
proper instruments acknowledging satisfaction and discharge of this Indenture 
when

               (1)  either

               (a)  all the Securities theretofore authenticated and 
delivered (other than lost, stolen or destroyed Securities which have been 
replaced or paid as provided in Section 308 have been cancelled or have been 
delivered to the Trustee for cancellation; or

               (b)  all Securities not theretofore delivered to the Trustee 
for cancellation

                            (i) have become due and payable,


                                      38

                           (ii) will become due and payable at their Stated 
Maturity within one year, or

                          (iii) are to be called for redemption within one 
year under arrangements satisfactory to the Trustee for the giving of notice 
of redemption by the Trustee in the name, and at the expense, of the Company, 
and the Company or any Guarantor has irrevocably deposited or caused to be 
deposited with the Trustee funds in an amount sufficient to pay and discharge 
the entire Indebtedness on the Securities not theretofore delivered to the 
Trustee for cancellation, including principal of, premium, if any, accrued 
interest and any Additional Amounts at such Stated Maturity or redemption 
date;

               (2)  the Company or any Guarantor has paid or caused to be 
paid all other sums payable under this Indenture by the Company and each 
Guarantor, including all fees and expenses of the Trustee; and

               (3)  the Company has delivered to the Trustee an Officers' 
Certificate and an Opinion of Counsel each stating that (a) all conditions 
precedent hereunder relating to the satisfaction and discharge of this 
Indenture have been complied with and (b) such satisfaction and discharge 
will not result in a breach or violation of, or constitute a default under, 
this Indenture.

               Notwithstanding satisfaction and discharge of this Indenture, 
the obligations of the Company to the Trustee under Section 606 and, if money 
shall have been deposited with the Trustee pursuant to subclause (b) of 
clause (1) of this Section, the obligations of the Trustee under Section 402 
and the last paragraph of Section 1003 shall survive any such satisfaction 
and discharge.

               SECTION 402.  APPLICATION OF TRUST MONEY.  Subject to the 
provisions of the last paragraph of Section 1003, all money deposited with 
the Trustee pursuant to Section 401 shall be held in trust and applied by it, 
in accordance with the provisions of the Securities and this Indenture, to 
the payment, either directly or through any Paying Agent (including the 
Company acting as its own Paying Agent) as the Trustee may determine, to the 
Persons entitled thereto, of the principal (and premium, if any), interest 
and Additional Amounts, if any, for whose payment such money has been 
deposited with the Trustee; but such money need not be segregated from other 
funds except to the extent required by law.

               If the Trustee or Paying Agent is unable to apply any money or 
U.S.  Government Obligations in accordance with Section 401 by reason of any 
legal proceeding or by reason of any order or judgment of any court or 
governmental authority enjoining, restraining or otherwise prohibiting such 
application, the Company's and the Guarantors' obligations under this 
Indenture and the Securities shall be revived and reinstated as though no 
deposit had occurred pursuant to Section 401; PROVIDED that if the Company 
and the Guarantors have made any payment of principal of, premium, if any, 
interest or Additional Amounts, if any, on any Securities because of the 
reinstatement of such obligations, the Company and the Guarantors shall be 
subrogated to the rights of the Holders of such Securities to receive such 
payment from the money or Government Obligations held by the Trustee or 
Paying Agent.

               SECTION 502.  ACCELERATION OF MATURITY; RESCISSION AND 
ANNULMENT.  If an Event of Default (other than as specified in Section 501(7) 
or 501(8)) shall occur and be continuing, the Trustee or the Holders of not 
less than 25% in aggregate principal amount of the Securities then 
Outstanding may, and the Trustee at the request of such Holders shall, 
declare all unpaid principal of (and premium, if any, on), accrued interest 
and Additional Amounts, if any, on all the Securities to be due and payable 
immediately, by a notice in writing to the Company (and to the Trustee if 
given by the Holders of the Securities); PROVIDED that so long as the Credit 
Facilities are in effect, such declaration shall not become effective until 
the earlier of (a) five Business Days after receipt of such notice of 
acceleration from the Holders or the Trustee by the agent under the Credit 
Facilities or (b) acceleration of the Indebtedness under the Credit 
Facilities. Thereupon such principal shall become immediately due and 
payable, and the Trustee may, at its discretion, proceed to protect and 
enforce the rights of the Holders of Securities by appropriate judicial 
proceeding. If an Event of Default specified in Section 501(7) or 501(8) 


                                      41

occurs, then all the Securities shall IPSO FACTO become and be immediately 
due and payable, in an amount equal to the principal amount of the 
Securities, together with accrued and unpaid interest, if any, to the date 
the Securities become due and payable, without any declaration or other act 
on the part of the Trustee or any Holder. The Trustee or, if notice of 
acceleration is given by the Holders, the Holders shall give notice to the 
agent under the Credit Facilities of any such acceleration; PROVIDED that 
failure to give such notice shall not affect the validity thereof.

               At any time after a declaration of acceleration has been made, 
but before a judgment or decree for payment of the money due has been 
obtained by the Trustee, the Holders of a majority in aggregate principal 
amount of Securities Outstanding, by written notice to the Company and the 
Trustee, may rescind and annul such declaration and its consequences if:

               (1) the Company has paid or deposited with the Trustee a sum 
sufficient to pay:

               (a) all sums paid or advanced by the Trustee hereunder and 
the reasonable compensation, expenses, disbursements and advances of the 
Trustee, its agents and counsel,

               (b) all overdue interest on all Securities, and

               (c) to the extent that payment of such interest is lawful, 
interest upon overdue interest at the rate borne by the Securities;

               (2) all Events of Default, other than the non-payment of 
principal of the Securities which have become due solely by such declaration 
of acceleration, have been cured or waived as provided in Section 513; and

               (3) the rescission will not conflict with any judgment or 
decree of a court of competent jurisdiction.

               No such rescission shall affect any subsequent default or 
impair any right consequent thereon.

               SECTION 503.  COLLECTION OF INDEBTEDNESS AND SUITS FOR 
ENFORCEMENT BY TRUSTEE.  The Company covenants that if:

               (a) default is made in the payment of any installment of 
interest on any Security when such interest becomes due and payable and such 
default continues for a period of 30 days, or

               (b) default is made in the payment of the principal of (or 
premium, if any, on) any Security at the Maturity thereof,

               the Company will, upon demand of the Trustee, pay to the 
Trustee for the benefit of the Holders of such Securities, the whole amount 
then due and payable on such Securities for principal (and premium, if any), 
interest and Additional Amounts, if any, and interest on any overdue 
principal (and premium, if any) and, to the extent that payment of such 
interest shall be legally enforceable, upon any overdue installment of 
interest and Additional Amounts, if any, at


                                      42

the rate borne by the Securities, and, in addition thereto, such further 
amount as shall be sufficient to cover the costs and expenses of collection, 
including the reasonable compensation, expenses, disbursements and advances 
of the Trustee, its agents and counsel, except costs and expenses incurred as 
a result of the Trustee's negligence or bad faith.

               If the Company fails to pay such amounts forthwith upon such 
demand, the Trustee, in its own name as trustee of an express trust, may 
institute a judicial proceeding for the collection of the sums so due and 
unpaid, may prosecute such proceeding to judgment or final decree and may 
enforce the same against the Company, any Guarantor, or any other obligor 
upon the Securities and collect the moneys adjudged or decreed to be payable 
in the manner provided by law out of the property of the Company, any 
Guarantor, or any other obligor upon the Securities, wherever situated.

               If an Event of Default occurs and is continuing, the Trustee 
may in its discretion proceed to protect and enforce its rights and the 
rights of the Holders by such appropriate judicial proceedings as the Trustee 
shall deem most effectual to protect and enforce any such rights, whether for 
the specific enforcement of any covenant or agreement in this Indenture or in 
aid of the exercise of any power granted herein, or to enforce any other 
proper remedy.

               SECTION 504.  TRUSTEE MAY FILE PROOFS OF CLAIM.  In case of 
the pendency of any receivership, insolvency, liquidation, bankruptcy, 
reorganization, arrangement, adjustment, composition or other judicial 
proceeding relative to the Company or any other obligor upon the Securities 
or the property of the Company or of such other obligor or their creditors, 
the Trustee (irrespective of whether the principal of the Securities shall 
then be due and payable as therein expressed or by declaration or otherwise 
and irrespective of whether the Trustee shall have made any demand on the 
Company for the payment of overdue principal, premium, if any, interest or 
Additional Amounts, if any) shall be entitled and empowered, by intervention 
in such proceeding or otherwise,

               (i) to file and prove a claim for the whole amount of 
principal (and premium, if any) and interest owing and unpaid in respect of 
the Securities and to file such other papers or documents as may be necessary 
or advisable in order to have the claims of the Trustee (including any claim 
for the reasonable compensation, expenses, disbursements and advances of the 
Trustee, its agents and counsel, unless incurred as a result of the Trustee's 
negligence or bad faith) and of the Holders allowed in such judicial 
proceeding, and

               (ii) to collect and receive any moneys or other property 
payable or deliverable on any such claims and to distribute the same;

               and any custodian, receiver, assignee, trustee, liquidator, 
sequestrator or similar official in any such judicial proceeding is hereby 
authorized by each Holder to make such payments to the Trustee and, in the 
event that the Trustee shall consent to the making of such payments directly 
to the Holders, to pay the Trustee any amount due it for the reasonable 
- -compensation, expenses, disbursements and advances of the Trustee, its 
agents and counsel, unless incurred as a result of the Trustee's negligence 
or bad faith, and any other amounts due the Trustee under Section 606.


                                      43

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

               SECTION 505.  TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF 
SECURITIES.  All rights of action and claims under this Indenture or the 
Securities may be prosecuted and enforced by the Trustee without the 
possession of any of the Securities or the production thereof in any 
proceeding relating thereto, and any such proceeding instituted by the 
Trustee shall be brought in its own name and as trustee of an express trust, 
and any recovery of judgment shall, after provision for the payment of the 
reasonable compensation, expenses, disbursements and advances of the Trustee, 
its agents and counsel, be for the ratable benefit of the Holders in respect 
of which such judgment has been recovered.

               SECTION 506.  APPLICATION OF MONEY COLLECTED.  Any money 
collected by the Trustee pursuant to this Article shall be applied in the 
following order, at the date or dates filed by the Trustee and, in case of 
the distribution of such money on account of principal (or premium, if any) 
or interest, upon presentation of the Securities and the notation thereon of 
the payment if only partially paid and upon surrender thereof if fully paid:

               FIRST:  To the payment of all amounts due the Trustee under 
Section 606;

               SECOND:  To the payment of the amounts then due and unpaid for 
principal of (and premium, if any, on,), interest and Additional Amounts, if 
any, on the Securities in respect of which or for the benefit of which such 
money has been collected, ratably, without preference or priority of any 
kind, according to the amounts due and payable on such Securities for 
principal (and premium, if any), interest and Additional Amounts, if any, 
respectively; and

               THIRD:  The balance, if any, to the Company.

               SECTION 507.  LIMITATION ON SUITS.  No Holder shall have any 
right to institute any proceeding, judicial or otherwise, with respect to 
this Indenture, or for the appointment of a receiver or trustee, or for any 
other remedy hereunder, unless

               (1)  such Holder has previously given written notice to the 
Trustee of a continuing Event of Default;

               (2)  the Holders of not less than 25% in principal amount of 
the Outstanding Securities shall have made written request to the Trustee to 
institute proceedings in respect of such Event of Default in its own name as 
Trustee hereunder;

               (3)  such Holder or Holders have offered to the Trustee 
reasonable indemnity against the costs, expenses and liabilities to be 
incurred in compliance with such request;

               (4)  the Trustee for 30 days after its receipt of such notice, 
request and offer of indemnity has failed to institute any such proceeding; 
and


                                      44

               (5)  no direction inconsistent with such written request has 
been given to the Trustee during such 30-day period by the Holders of a 
majority or more in principal amount of the Outstanding Securities;

               it being understood and intended that no one or more Holders 
shall have any right in any manner whatever by virtue of, or by availing of, 
any provision of this Indenture to affect, disturb or prejudice the rights of 
any other Holders, or to obtain or to seek to obtain priority or preference 
over any other Holders or to enforce any right under this Indenture, except 
in the manner herein provided and for the equal and ratable benefit of all 
the Holders.

               SECTION 508.  UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE 
PRINCIPAL, PREMIUM , INTEREST AND ADDITIONAL AMOUNTS.  Notwithstanding any 
other provision in this Indenture, the Holder of any Security shall have the 
right, which is absolute and unconditional, to receive payment, as provided 
herein (including, if applicable, Article Twelve) and in such Security of the 
principal of (and premium, if any, on), interest (subject to Section 309) and 
Additional Amounts, if any, on such Security on the respective Stated 
Maturities expressed in such Security (or, in the case of redemption, on the 
Redemption Date) and to institute suit for the enforcement of any such 
payment, and such rights shall not be impaired without the consent of such 
Holder.

               SECTION 509.  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 such 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.

               SECTION 510.  RIGHTS AND REMEDIES CUMULATIVE.  Except as 
otherwise provided with respect to the replacement or payment of mutilated, 
destroyed, lost or stolen Securities in the last paragraph of Section 308, no 
right or remedy herein conferred upon or reserved to the Trustee or to the 
Holders is intended to be exclusive of any other right or remedy, and every 
right and remedy shall, to the extent permitted by law, be cumulative and in 
addition to every other right and remedy given hereunder or now or hereafter 
existing at law or in equity or otherwise. The assertion or employment of any 
right or remedy hereunder, or otherwise, shall not prevent the concurrent 
assertion or employment of any other appropriate right or remedy.

               SECTION 511.  DELAY OR OMISSION NOT WAIVER.  No delay or 
omission of the Trustee or of any Holder of any Security to exercise any 
right or remedy accruing upon any Event of Default shall impair any such 
right or remedy or constitute a waiver of any such Event of Default or an 
acquiescence therein. Every right and remedy given by this Article or by law 
to the Trustee or to the Holders may be exercised from time to time, and as 
often as may be deemed expedient, by the Trustee or by the Holders, as the 
case may be.

               SECTION 512.  CONTROL BY HOLDERS.  The Holders of not less 
than a majority in principal amount of the Outstanding Securities shall have 
the right to direct the time, method and


                                      45


place of conducting any proceeding for any remedy available to the Trustee, 
or exercising any trust or power conferred on the Trustee, PROVIDED that

               (1) such direction shall not be in conflict with any rule of 
law or with this Indenture,

               (2) subject to the provision of Section 315 of the Trust

it in personal liability or be unjustly prejudicial to the Holders not 
consenting.

               SECTION 513.  WAIVER OF PAST DEFAULTS.  The Holders of not 
less than a majority in principal amount of the Outstanding Securities may on 
behalf of the Holders of all the Securities waive any past default hereunder

if any, on), interest and Additional Amounts, if any, on any Security, or

               (2) in respect of a covenant or provision hereof which under 
Article Nine cannot be modified or amended without the consent of the Holder 
of each Outstanding Security affected.

               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 thereon.

               SECTION 514.  WAIVER OF STAY OR EXTENSION LAWS.  The Company 
and each Guarantor covenants (to the extent that it may lawfully do so) that 
it will not at any time insist upon, or plead, or in any manner whatsoever 
claim or take the benefit or advantage of, any stay or extension law wherever 
enacted, now or at any time hereafter in force, which may affect the 
covenants or the performance of this Indenture; and the Company and each 
Guarantor (to the extent that it may lawfully do so) 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 515.  UNDERTAKING FOR COSTS.    In any suit for the 
enforcement of any right or remedy under this Indenture or the Securities or 
in any suit against the Trustee for any action taken or omitted by it as 
Trustee, a court in its discretion may require the filing by any party 
litigant in the suit of an undertaking to pay the costs of the suit, and the 
court in its discretion may assess reasonable costs, including reasonable 
attorneys' fees and expenses, against any party litigant in the suit, having 
due regard to the merits and good faith of the claims or defenses made by the 
party litigant. This Section does not apply to a suit by the Trustee or a 
suit by Holders of more than 10% in principal amount of the Securities.

               (1)    to pay to the Trustee from time to time such

provision of law in regard to the compensation of a trustee of an express 
trust);

               (2)    except as otherwise expressly provided herein, to 
reimburse the Trustee upon its request for all reasonable expenses, 
disbursements and advances incurred or made by the Trustee in accordance with

on its part, arising out of or in connection with the acceptance or 
administration of this trust, including the 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.

disbursements and advances and to indemnify and hold harmless the Trustee 
shall constitute additional indebtedness hereunder and shall survive the 
satisfaction and discharge of this Indenture. As security for the performance 
of such obligations of the Company, the Trustee shall have a lien prior to 
the Securities upon all property and funds held or collected by the Trustee 
as such, except funds held in trust for the payment of principal of (and

501(8), the expenses (including the reasonable charges and expenses of its 
counsel) and the compensation for the services are intended to constitute 
expenses of administration under any applicable federal or state bankruptcy, 
insolvency or other similar law.

               SECTION 607.  CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.  There

territorial or District of Columbia supervising or examining authority, then 
for the purposes of this Section, the combined capital and surplus of such 
corporation shall be deemed to be its combined capital and surplus as set 
forth in its most recent report of condition so published. If at any time the 
Trustee shall cease to be eligible in accordance with the provisions of this 
Section, it shall resign promptly in the manner and with the effect 
hereinafter specified in this Article.

SUCCESSOR.  (a)   No resignation or removal of the Trustee and no appointment 
of a successor Trustee pursuant to this Article shall become effective until 
the acceptance of appointment by the successor Trustee in accordance with the 
applicable requirements of Section 609.

               (b)    The Trustee may resign at any time by giving written 
notice thereof to the Company.  If the instrument of acceptance by a 
successor Trustee required by Section 609 shall not have been delivered to 
the Trustee within 30 days after the giving of such notice of resignation, 
the resigning Trustee may petition any court of competent jurisdiction for 
the appointment of a successor Trustee.

               (c)    The Trustee may be removed at any time by Act of the 
Holders of not less than a majority in principal amount of the Outstanding 
Securities, delivered to the Trustee and to the Company.

               (d)    If at any time:

               (1)    the Trustee shall fail to comply with the provisions of 
TIA Section 310(b) after written request therefor by the Company or by any 
Holder who has been a bona fide Holder of a Security for at least six months, 
or

               (2)    the Trustee shall cease to be eligible under Section 
607(a) and shall fail to resign after written request therefor by the Company 
or by any Holder who has been a bona fide Holder of a Security for at least 
six months, or

               (3)    the Trustee shall become incapable of acting or shall 
be adjudged a bankrupt or insolvent or a receiver of the Trustee or of its 
property shall be appointed or any public officer shall take charge or 
control of the Trustee or of its property or affairs for the purpose of 
rehabilitation, conservation or liquidation,

               then, in any such case, (i) the Company, by a Board 
Resolution, may remove the Trustee, or (ii) subject to TIA Section 315(e), 
any Holder who has been a bona fide Holder of a Security for at least six 
months may, on behalf of himself and all others similarly situated, petition 
any court of competent jurisdiction for the removal of the Trustee and the 
appointment of a successor Trustee.

               (e)    If the Trustee shall resign, be removed or become 
incapable of acting, or if a vacancy shall occur in the office of Trustee for 
any cause, the Company, by a Board Resolution, shall promptly appoint a 
successor trustee. If, within one year after such resignation, removal or 
incapability, or the occurrence of such vacancy, a successor trustee shall be 
appointed by Act of the Holders of a majority in principal amount of the 
Outstanding Securities delivered to the Company and the retiring Trustee, the 
successor trustee so appointed shall, forthwith upon




                                      50


its acceptance of such appointment, become the successor trustee and 
supersede the successor trustee appointed by the Company. If no successor 
trustee shall have been so appointed by the Company or the Holders and 
accepted appointment in the manner hereinafter provided, any Holder who has 
been a bona fide Holder of a Security for at least six months may, on behalf 
of himself and all others similarly situated, petition any court of competent 
jurisdiction for the appointment of a successor trustee.

               (f)    The Company shall give notice of each resignation and 
each removal of the Trustee and each appointment of a successor trustee to 
the Holders of Securities in the manner provided for in Section 106. Each 
notice shall include the name of the successor trustee and the address of its 
Corporate Trust Office.

               SECTION 609.  ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.  Every 
successor trustee appointed hereunder shall execute, acknowledge and deliver 
to the Company and to the retiring Trustee an instrument accepting such 
appointment, and thereupon the resignation or removal of the retiring Trustee 
shall become effective and such successor trustee, without any further act, 
deed or conveyance, shall become vested with all the rights, powers, trusts 
and duties of the retiring Trustee; but, on request of the Company or the 
successor trustee, such retiring Trustee shall, upon payment of its charges, 
execute and deliver an instrument transferring to such successor trustee all 
the rights, powers and trusts of the retiring Trustee and shall duly assign, 
transfer and deliver to such successor trustee all property and money held by 
such retiring Trustee hereunder. Upon request of any such successor trustee, 
the Company shall execute any and all instruments for more fully and 
certainly vesting in and confirming to such successor trustee all such 
rights, powers and trusts.

               No successor trustee shall accept its appointment unless at 
the time of such acceptance such successor trustee shall be qualified and 
eligible under this Article.

               SECTION 610.  MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION 
TO BUSINESS.  Any corporation into which the Trustee may be merged or 
converted or with which it may be consolidated, or any corporation resulting 
from any merger, conversion or consolidation to which the Trustee shall be a 
party, or any corporation succeeding to all or substantially all of the 
corporate trust business of the Trustee, shall be the successor of the 
Trustee hereunder, provided such corporation shall be otherwise qualified and 
eligible under this Article, without the execution or filing of any paper or 
any further act on the part of any of the parties hereto. In case any 
Securities shall have been authenticated, but not delivered, by the Trustee 
then in office, any successor by merger, conversion or consolidation to such 
authenticating Trustee may adopt such authentication and deliver the 
Securities so authenticated with the same effect as if such successor trustee 
had itself authenticated such Securities; and in case at that time any of the 
Securities shall not have been authenticated, any successor trustee may, upon 
receipt of a Company Order, authenticate such Securities either in the name 
of any predecessor hereunder or in the name of the successor trustee; and in 
all such cases such certificates shall have the full force which it is 
anywhere in the Securities or in this Indenture provided that the certificate 
of the Trustee shall have; PROVIDED, HOWEVER, that the right to adopt the 
certificate of authentication of any predecessor Trustee or to authenticate 
Securities in the name of any predecessor Trustee shall apply only to its 
successor or successors by merger, conversion or consolidation.

                                  COVENANTS

               SECTION 1001.  PAYMENT OF PRINCIPAL, PREMIUM, IF ANY,  
INTEREST AND ADDITIONAL AMOUNTS, IF ANY.  The Company covenants and agrees 
for the benefit of the Holders that it will duly and punctually pay the

any, on the Securities in accordance with the terms of the Securities and 
this Indenture.

               SECTION 1002.  MAINTENANCE OF OFFICE OR AGENCY.  The Company 
will maintain an office or agency where Securities may be presented or 
surrendered for payment, where Securities may be surrendered for registration 
of transfer or exchange and where notices and demands to or upon the Company 
in respect of the Securities and this Indenture may be served. The Corporate 
Trust Office of the Trustee shall be such office or agency of the Company, 
unless the Company shall designate and maintain some other office or agency 
for one or more of such purposes. The Company will give prompt written notice 
to the Trustee of any change in the location of any such office or agency. If 
at any time the Company shall fail to maintain any such required office or 
agency or shall fail to furnish the Trustee with the address thereof, such 
presentations, surrenders, notices and demands may be made or served at the 
Corporate Trust Office of the Trustee, and the Company hereby appoints the 
Trustee as its agent to receive all such presentations, surrenders, notices 
and demands.

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

               SECTION 1003.  MONEY FOR SECURITY PAYMENTS TO BE HELD IN 
TRUST.  If the Company shall at any time act as its own Paying Agent, it 
will, on or before each due day of the principal of (and premium, if any, 
on), interest or Additional Amounts, if any, on any of the Securities, 
segregate and hold in trust for the benefit of the Persons entitled thereto a 
sum sufficient to pay the principal (and premium, if any), interest or 
Additional Amounts so becoming due until such sums shall be paid to such 
Persons or otherwise disposed of as herein provided and will promptly notify 
the Trustee of its action or failure so to act.

               Whenever the Company shall have one or more Paying Agents for 
the Securities, it will, on or before each due date of the principal of (and 
premium, if any, on), interest or Additional Amounts, if any, on any 
Securities, deposit with a Paying Agent a sum sufficient to pay the principal 
(and premium, if any), interest or Additional Amounts, if any, so becoming 
due, such sum to be held in trust for the benefit of the Persons entitled to 
such principal, premium, interest or Additional Amounts and (unless such 
Paying Agent is the Trustee) the Company will promptly notify the Trustee of 
such action or any failure so to act.




                                      57


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

               (1)    hold all sums held by it for the payment of the 
principal of (and premium, if any, on), interest or Additional Amounts, if 
any, on Securities in trust for the benefit of the Persons entitled thereto 
until such sums shall be paid to such Persons or otherwise disposed of as 
herein provided;

               (2)    give the Trustee notice of any default by the Company 
(or any other obligor upon the Securities) in the making of any payment of 
principal (and premium, if any), interest or Additional Amounts, if any; and

               (3)    at any time during the continuance of any such default, 
upon the written request of the Trustee, forthwith pay to the Trustee all 
sums so held in trust by such Paying Agent.

               The Company may at any time, for the purpose of obtaining the 
satisfaction and discharge of this Indenture or for any other purpose, pay, 
or by Company Order direct any Paying Agent to pay, to the Trustee all sums 
held in trust by the Company or such Paying Agent, such sums to be held by 
the Trustee upon the same trusts as those upon which such sums were held by 
the Company or such Paying Agent; and, upon such payment by any Paying Agent 
to the Trustee, such Paying Agent shall be released from all further 
liability with respect to such sums.

               Any money deposited with the Trustee or any Paying Agent, or 
then held by the Company, in trust for the payment of thc principal of (and 
premium, if any, on), interest or Additional Amounts, if any, on any Security 
and remaining unclaimed for two years after such principal (and premium, if 
any), interest or Additional Amounts, if any, has become due and payable 
shall be paid to the Company on Company Request, or (if then held by the 
Company) shall be discharged from such trust; and the Holder of such Security 
shall thereafter, as an unsecured general creditor, look only to the Company 
for payment thereof, and all liability of the Trustee or such Paying Agent 
with respect to such trust money, and all liability of the Company as trustee 
thereof, shall thereupon cease; PROVIDED, HOWEVER, that the Trustee or such 
Paying Agent, before being required to make any such repayment, may at the 
expense of the Company cause to be published once, in a newspaper published 
in the English language, customarily published on each Business Day and of 
general circulation in the Borough of Manhattan, The City of New York, 
reasonable notice under the circumstances 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 publication, any unclaimed balance of such money 
then remaining will be repaid to the Company.

               SECTION 1004.  CORPORATE EXISTENCE.  Subject to Article Eight, 
and as long as any Securities remain Outstanding, each of United and the 
Company will do or cause to be done all things necessary to preserve and keep 
in full force and effect the corporate existence, rights (charter and 
statutory) and franchises of the Company and each Subsidiary; PROVIDED, 
HOWEVER, that the Company shall not be required to preserve any such right or 
franchise if the Board of Directors shall determine that the preservation 
thereof is no longer desirable in the conduct of the




                                      58

business of the Company and its Subsidiaries as a whole and that the loss 
thereof is not disadvantageous in any material respect to the Holders.

               SECTION 1005.  PAYMENT OF TAXES AND OTHER CLAIMS.  Each of 
United and the Company will pay or discharge or cause to be paid or 
discharged, before the same shall become delinquent, (a) all taxes, 
assessments and governmental charges levied or imposed upon United, the 
Company or any Subsidiary or upon the income, profits or property of United, 
the Company or any Subsidiary and (b) all lawful claims for labor, materials 
and supplies, which, if unpaid, might by law become a lien upon the property 
of United, the Company or any Subsidiary; PROVIDED, HOWEVER, that United or 
the Company shall not be required to pay or discharge or cause to be paid or 
discharged any such tax, assessment, charge or claim (1) the amount, 
applicability or validity of which is being contested in good faith by 
appropriate proceedings or (2) the nonpayment or delayed payment of which 
would not have a material adverse effect on Holders.

               SECTION 1006.  MAINTENANCE OF PROPERTIES.  Each of United and 
the Company will cause all material properties owned by United, the Company 
or any Subsidiary or used or held for use in the conduct of its business or 
the business of any Subsidiary to be maintained and kept in good condition, 
repair and working order and supplied with all necessary equipment and will 
cause to be made all necessary repairs, renewals, replacements, betterments 
and improvements thereof, all as in the judgment of United or the Company may 
be necessary so that the business carried on in connection therewith may be 
properly and advantageously conducted at all times; PROVIDED, HOWEVER, that 
nothing in this Section shall prevent United or the Company (i) from 
discontinuing the maintenance of any of such properties if such 
discontinuance is, in the judgment of United or the Company, desirable in the 
conduct of its business or the business of any Subsidiary and not 
disadvantageous in any material respect to the Holders or (ii) selling any 
properties or taking any action in accordance with Article Eight or Section 
1016.

               SECTION 1007.  INSURANCE.  Each of United and the Company will 
at all times keep all of its and its Subsidiaries' properties which are of an 
insurable nature insured with insurers, believed by United and the Company to

character is usually so insured by corporations similarly situated and owning 
like properties.

               SECTION 1008.  STATEMENT BY OFFICERS AS TO DEFAULT.  (a) The 
Company will deliver to the Trustee, within 45 days after the end of each 
fiscal quarter (or 90 days, in the case of the last fiscal quarter of each 
fiscal year), a brief certificate from the principal executive officer, 
principal financial officer or principal accounting officer as to his or her 
knowledge of the Company's compliance with all conditions and covenants under 
this Indenture. Such certificate shall state that such officer has reviewed 
this Indenture and believes that either (a) the Company and Guarantors are in 
compliance with terms thereof or (b) the Company and Guarantors are not in 
compliance with terms thereof. For purposes of this Section 1008(a), such 
compliance shall be determined without regard to any period of grace or 
requirement of notice under this Indenture.

               (b)    When any Default has occurred and is continuing under 
this Indenture, or if the trustee for or the holder of any other evidence of 
Indebtedness of the Company, any




                                      59


Guarantor or any Subsidiary gives any notice or takes any other action with 
respect to a claimed default (other than with respect to Indebtedness in the 
principal amount of less than $1,000,000), the Company shall deliver to the 
Trustee by registered or certified mail or by telegram, telex or facsimile 
transmission an Officers' Certificate specifying such event, notice or other 
action within five Business Days of its occurrence.

connection with their audit examination, anything came to their attention 
that caused them to believe that the Company was not in compliance with any 
of the terms, covenants, provisions or conditions of Article Ten and Section 
8.01 of this Indenture as they pertain to accounting matters and, if any 
Default or Event of Default has come to their attention, specifying the 
nature and period of existence thereof; PROVIDED that such independent 
certified public accountants shall not be liable in respect of such statement 
by reason of any failure to obtain knowledge of any such Default or Event of 
Default that would not be disclosed in the course of an audit examination 
conducted in accordance with generally accepted auditing standards in effect 
at the date of such examination.

               SECTION 1009.  PROVISION OF FINANCIAL STATEMENTS.  Whether or 
not United or the Company is subject to Section 13(a) or 15(d) of the 
Exchange Act, United and the Company will, to the extent permitted under the 
Exchange Act, deliver to the Commission for filing the annual reports, 
quarterly reports and other documents which United and the Company would have 
been required to file with the Commission pursuant to such Section 13(a) or 
15(d) if United and the Company were so subject, such documents to be filed 
with the Commission on or prior to the respective dates (the "REQUIRED FILING 
DATES") by which United and the Company would have been required to so file 
such documents if United and the Company, were so subject (subject to a five 
day grace period). United and the Company will also in any event (x) within 
15 days of each Required Filing Date (subject to a five day grace period) (i) 
transmit by mail to all Holders, as their names and addresses appear in the 
security register, without cost to such Holders and (ii) file with the 
Trustee copies of the annual reports, quarterly reports and other documents 
which United and the Company would have been required to file with the 
Commission pursuant to Section 13(a) or 15(d) of the Exchange Act if United 
and the Company were subject to such Sections and (y) if filing such 
documents by United and the Company with the Commission is not permitted 
under the Exchange Act, promptly upon written request, supply copies of such 
documents to any prospective Holder at United's and the Company's cost. The 
Company and United will also provide the information required by Rule 144A to 
any Holder or prospective Holder of Securities.

               Delivery of such reports, information and documents to the 
Trustee is for informational purposes only and the Trustee's 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).




                                      60

If a Change of Control shall occur at any time, then the Company shall be 
obligated to make an offer to purchase all of the Outstanding Notes (a 
"CHANGE OF CONTROL OFFER") and the Company shall purchase all of the then 
Outstanding Notes validly tendered pursuant to such Change of Control Offer, 
in whole or in part in integral multiples of $1,000, at a purchase price (the

principal amount of such Notes, plus accrued and unpaid interest and 
Additional Amounts, if any, to the date of purchase (the "CHANGE OF CONTROL 
PURCHASE DATE"), pursuant to the procedures set forth in paragraphs (b), (c) 
and (d) of this Section.

               (b)    Within 30 days following the date upon which the 
Company becomes aware that any Change of Control has occurred, the Company 
shall notify the Trustee thereof and shall give to each Holder of the 
Securities in the manner provided in Section 106, a notice stating:

               (l)    that a Change of Control has occurred and that such 
Holder has the right to require the Company to repurchase such Holder's Notes 
at the Change of Control Purchase Price;

               (2)    the Change of Control Purchase Price and the Change of 
Control Purchase Date, which shall be a Business Day no earlier than 30 days 
nor later than 60 days from the date such notice is mailed, or such later 
date as is necessary to comply with requirements under the Exchange Act;

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

               (4)    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 Purchase Date; and

               (5)    the procedures that a Holder must follow to accept a 
Change of Control Offer or to withdraw such acceptance.

               (c)    Holders electing to have Notes purchased will be 
required to surrender such Securities with the execution form provided for in 
Exhibit A duly executed to the Company at the address specified in the notice 
at least 10 Business Days prior to the Change of Control Purchase Date. 
Holders will be entitled to withdraw their election if the Company receives, 
not later than three Business Days prior to the Change of Control Purchase 
Date, a facsimile transmission or letter setting forth the name of the 
Holder, the principal amount of the Securities delivered for purchase by the 
Holder as to which his election is to be withdrawn and a statement that such 
Holder is withdrawing his election to have such Notes purchased. Holders 
whose Notes are purchased only in part will be issued new Notes equal in 
principal amount to the unpurchased portion of the Notes surrendered.

               (d)   The Company will comply with any applicable tender offer 
rules, including Rule 14e-1 under the Exchange Act, and any other applicable 
securities laws or regulations in connection with a Change of Control Offer. 
To the extent that the provisions of any securities laws or regulations 
conflict with provisions of this Section, the Company shall




                                      61


comply with the applicable securities laws and regulations and shall not be 
deemed to have breached its obligations under this Section by virtue thereof.

               (e)   United will not, and will not permit any Subsidiary to, 
create or permit to exist or become effective any restriction (other than 
restrictions in effect on the Issue Date with respect to Indebtedness 
outstanding on the Issue Date and refinancings thereof and customary default 
provisions) that would materially impair the ability of the Company to make a 
Change of Control Offer to purchase the Notes or, if such Change of Control 
Offer is made, to pay for the Notes tendered for purchase.

               SECTION 1011.  LIMITATION ON INDEBTEDNESS.  (a)  The Company 
will not, and will not permit any of its Restricted Subsidiaries to, create, 
issue, assume, incur, guarantee, or otherwise in any manner become directly 
or indirectly liable for (collectively, "INCUR") any Indebtedness (including 
any Acquired Indebtedness); PROVIDED that the Company may incur Indebtedness 
(including any Acquired Indebtedness) (A) if the Consolidated Fixed Charge 
Coverage Ratio of the Company for the four full fiscal quarters immediately 
preceding the incurrence of such Indebtedness (and for which such financial 
information is available) taken as one period is at least equal to 2.00:1.00 
and (B) if such Indebtedness is Subordinated Indebtedness, such Indebtedness 
shall have an Average Life to Stated Maturity longer than the Average Life to 
Stated Maturity of the Notes and a final Stated Maturity of principal later 
than the final Stated Maturity of principal of the Notes.

               (b)    The foregoing limitation will not apply to the 
incurrence of any of the following (collectively, "PERMITTED INDEBTEDNESS"):

                      (i)    Indebtedness of the Company incurred pursuant to

            governing Senior Indebtedness outstanding at any time in an 
            aggregate principal amount not to exceed the greater of (x) the 
            sum of (I) $500.00 million and (II) if and when the 1998 
            Receivables Securitization Program is terminated and the Company

will not permit any Restricted Subsidiary to, directly or indirectly, incur, 
assume or suffer to exist any Lien of any kind upon any of its property or 
assets (including any shares of Capital Stock or Indebtedness of any 
Restricted Subsidiary), owned on the Issue Date or acquired after the Issue 
Date, or any income or profits therefrom, except if the Notes (or the 
Guarantee of the Notes, in the case of Liens on properties or assets of a 
Restricted Subsidiary that is a Guarantor) and all other amounts due under 
this Indenture are directly secured equally and ratably with (or prior to in 
the case of Liens with respect to Subordinated Indebtedness) the obligation 
or liability secured by such Lien, excluding, however, from the operation of 
the foregoing any of the following:

               (a) any Lien existing or provided for under written 
arrangements existing as of the Issue Date;

not have expired; (ii) taxes, assessments or other governmental charges not

assets material to the operation of the business of the Company or any 
Restricted Subsidiary or the value of such property or assets for the purpose 
of such business; (vi) deposits to secure public or statutory obligations, or 
in lieu of surety or appeal bonds with respect to matters not yet finally

Company or any Guarantor securing Senior Indebtedness or Senior Guarantor 
Indebtedness, as the case may be, of such Person;

               (d) any Lien securing Acquired indebtedness created prior to 
(and not created in connection with, or in contemplation of) the incurrence 
of such Indebtedness by the Company, which Indebtedness is permitted under 
Section 1011; PROVIDED that any such Lien only extends to the assets that 
were subject to such Lien securing such Acquired indebtedness prior to the 
related acquisition;

               (e) any Lien now or hereafter existing on Receivables and 
Related Assets in connection with a Permitted Receivables Securitization 
Program;

               (f) any Lien on property, assets or shares of Capital Stock of 
a Person at the time such Person becomes a Subsidiary; PROVIDED, HOWEVER, 
such Lien is not created, incurred or assumed by such Person in connection 
with, or in contemplation of, such other Person becoming such a Subsidiary; 
provided further, however, that such Lien may not extend to any other 
property owned by the Company or any Restricted Subsidiary;

               (g) any Lien on property or assets at the time the Company or 
a Restricted Subsidiary acquired the property or assets, including any 
acquisition by means of a merger or consolidation with or into the Company or

connection with, or in contemplation of, such acquisition; PROVIDED FURTHER, 
HOWEVER, that the Lien may not extend to any other property owned by the 
Company or any Restricted Subsidiary;

               (h) Liens related to Capitalized Lease Obligations, mortgage 
financings or purchase money obligations (including refinancings thereof), in 
each case incurred in accordance with Section 1011 and for the purpose of 
financing all or any part of the purchase price or costs of construction or 
improvement of property, plant or equipment used in the business of the 
Company or any Restricted Subsidiary, provided that any such Lien encumbers 
only the asset or assets so financed, purchased, constructed or improved;

               (i)  any Lien on Capital Stock or other securities of an 
Unrestricted Subsidiary; and

               (j) any extension renewal, refinancing or replacement, in 
whole or in part, of any Lien described in the foregoing clauses (a) through 
(i) so long as the amount of property or assets subject to such Lien is not 
increased to any amount greater than the sum of (i) the outstanding principal 
amount or, if greater, committed amount of the Indebtedness described under 
such clauses (a) through (i) at the time the original Lien became a Lien 
permitted hereunder and (ii) an amount necessary to pay any fees and 
expenses, including premiums, related to such extension, renewal, refinancing 
or replacement.

               SECTION 1016.  LIMITATION ON SALE OF ASSETS.  (a)  The Company 
will not, and will not permit any of its Restricted Subsidiaries to, directly 
or indirectly, consummate an Asset Sale unless (i) at least 75% of the 
proceeds from such Asset Sale are received in cash and (ii) the


                                      70

Company or such Restricted Subsidiary receives consideration at the time of 
such Asset Sale at least equal to the Fair Market Value of the shares or 
assets sold.

               (b)  If all or a portion of the Net Cash Proceeds of any Asset 
Sale is not applied to repay permanently any Senior Indebtedness or Senior 
Guarantor Indebtedness then outstanding as required by the terms thereof, and 
the Company determines not to apply such Net Cash Proceeds to the prepayment 
of such Senior Indebtedness or Senior Guarantor Indebtedness or if no such 
Senior Indebtedness or Senior Guarantor Indebtedness is then outstanding, 
then the Company may, within 12 months of the Asset Sale, invest (or enter 
into a written, legally binding commitment to invest, PROVIDED that the 
investment provided for in such commitment is actually made within 24 months 
of the Asset Sale) the Net Cash Proceeds in other properties and assets that 
will be used in the businesses of the Company and its Restricted Subsidiaries 
or in any company having such properties and assets. The amount of such Net 
Cash Proceeds neither used to permanently repay or prepay Senior Indebtedness 
or Senior Guarantor Indebtedness nor used or invested as set forth in this 
paragraph (b) constitutes "EXCESS PROCEEDS."

               (c)  When the aggregate amount of Excess Proceeds equals $10.0 
million or more, the Company shall, within 15 Business Days in accordance 
with the procedures set forth in this Indenture: (i) make an offer (an 
"OFFER") to purchase, for cash, at 100% of the principal amount thereof, plus 
accrued and unpaid interest to the repurchase date (the "REPURCHASE DATE"), 
the maximum principal amount (expressed as a multiple of $1,000) of Notes 
that may be purchased out of an amount (the "NOTE AMOUNT") equal to the 
product of such Excess Proceeds multiplied by a fraction, the numerator of 
which is the outstanding principal amount of the Notes, and the denominator 
of which is the sum of the outstanding principal amount of the Notes and any 
Pari Passu Indebtedness that is required to be repurchased under the 
instrument governing such Pari Passu Indebtedness and (ii) to the extent 
required by such Pari Passu Indebtedness, the Company shall make an offer to 
purchase or, if required by the terms of such Pari Passu Indebtedness, 
otherwise repurchase or redeem Pari Passu Indebtedness (a "PARI PASSU 
REPAYMENT") in an amount (the "PARI PASSU DEBT AMOUNT") equal to the excess 
of the Excess Proceeds over the Note Amount; PROVIDED that in no event shall 
the Pari Passu Debt Amount exceed the principal amount of such Pari Passu 
Indebtedness plus the amount of any premium, if any, and accrued and unpaid 
interest required to be paid to repurchase such Pari Passu Indebtedness. To 
the extent that the aggregate principal amount of and accrued but unpaid 
interest with respect to the Notes tendered pursuant to the Offer is less 
than the Note Amount relating thereto or the aggregate amount of Pari Passu 
indebtedness that is purchased is less than the Pari Passu Debt Amount, the 
Company may use such amounts not necessary to purchase the tendered Notes and 
the Pari Passu Indebtedness required to be purchased for any purpose not 
prohibited by this Indenture. Upon completion of the purchase of all the 
Notes tendered pursuant to an Offer and the purchase of the Pari Passu 
Indebtedness pursuant to a Pari Passu Repayment, the amount of Excess 
Proceeds, if any, shall be reset at zero.

               (d) Within the period required by the first sentence of 
paragraph (c) above, the Company shall notify the Trustee thereof and shall 
give to each Holder of the Securities in the manner provided in Section 106, 
a notice stating:

               (1) that an Offer is being made and that such Holder has
            the right to require the Company to repurchase such Holder's
            Securities on a pro rata basis;


                                     71

               (2) the purchase price and the Repurchase Date, which
            shall be a Business Day no earlier than 30 days nor later than 60
            days from the date such notice is mailed, or such later date as may
            be necessary to comply with requirements under the Exchange Act;

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

               (4) that, unless the Company defaults in the payment of
            the purchase price, any Notes accepted for payment pursuant to the
            Offer shall cease to accrue interest after the Repurchase Date; and

               (5) the procedures that a Holder must follow to accept an Offer
            or to withdraw such acceptance.

               (e) Holders electing to have Notes purchased will be required 
to surrender such Notes with the execution form provided for in Exhibit A 
duly executed to the Company at the address specified in the notice at least 
10 Business Days prior to the Change of Control Repurchase Date. Holders will 
be entitled to withdraw their election if the Company receives, not later 
than three Business Days prior to the Change of Control Purchase Date, a 
facsimile transmission or letter setting forth the name of the Holder, the 
principal amount of the Notes delivered for purchase by the Holder as to 
which his election is to be withdrawn and a statement that such Holder is 
withdrawing his election to have such Notes purchased. Holders whose Notes 
are purchased only in part will be issued new Notes equal in principal amount 
to the unpurchased portion of the Notes surrendered.

               On the Repurchase Date, the Company shall repurchase Notes on 
the pro rata basis set forth in paragraph (c) above.

               (f) The Company will comply with the applicable tender offer 
rules, including Rule 14e-1 under the Exchange Act, and any other applicable 
securities laws and regulations in connection with an Offer.

               SECTION 1017.  LIMITATION ON ISSUANCES OF GUARANTEES OF 
INDEBTEDNESS.  (a)  The Company will not permit any Restricted Subsidiary to 
incur any Guaranteed Debt, other than Guaranteed Debt in respect of Senior 
Indebtedness of the Company; PROVIDED that, concurrently with the incurrence 
of such Guaranteed Debt by any Restricted Subsidiary, the Restricted 
Subsidiary incurring such Guaranteed Debt (if it is not a Guarantor) shall 
execute a supplemental indenture setting forth such Restricted Subsidiary's 
senior subordinated guarantee of the Notes, such guarantee to be on the same 
terms as each Guarantor's Guarantee of the Notes. Neither the Company nor any 
Guarantor shall be required to make a notation on the Notes or the Guarantees 
to reflect such Guarantee. In connection with such Guarantee of the Notes, 
such Restricted Subsidiary shall waive, and agree that it will not in any 
manner whatsoever claim or take the benefit or advantage of, any rights of 
reimbursement, indemnity or subrogation or any other rights against the 
Company or any Guarantor as a result of any payment by such Restricted 
Subsidiary with respect to such Guaranteed Debt.

               (b)  United will not incur any Guaranteed Debt with respect to 
any Pari Passu indebtedness or Subordinated Indebtedness unless such 
Guaranteed Debt is subordinated (at least


                                      72

to the extent that Notes are subordinated in right of payment to Senior 
Indebtedness) in right of payment to (or, in the case of Guaranteed Debt with 
respect to Pari Passu Indebtedness, is PARI PASSU in right of payment with) 
United's Guarantee of the Notes.

               (c) The Company will cause each of its domestic
Restricted Subsidiaries which incurs any Indebtedness, other than the Joint
Venture and any Securitization Subsidiary that has entered into or established a
Permitted Receivables Securitization Program, simultaneously with the first
incurrence of any Indebtedness, to execute a supplemental indenture providing
for a Guarantee of the Notes on the same terms as each Guarantor's Guarantee of
the Notes, including, without limitation, the waiver and agreement referred to
in the last sentence of paragraph (a) above. Neither the Company nor any
Guarantor shall be required to make a notation on the Notes or the Guarantees to
reflect such Guarantee.

               SECTION 1018.  LIMITATION ON SUBSIDIARY CAPITAL STOCK.  The 
Company will not transfer, and will not permit the transfer or issuance of, 
any Capital Stock of any Restricted Subsidiary (including options, warrants 
or other rights to purchase shares of such Capital Stock) except for (i) 
Capital Stock issued to and held by the Company or a Restricted Wholly Owned 
Subsidiary, (ii) Capital Stock issued by a Person prior to the time (A) such 
Person becomes a Restricted Subsidiary, (B) such Person merges with or into a 
Restricted Subsidiary or (C) a Restricted Subsidiary merges with or into such 
Person; PROVIDED that such Capital Stock was not issued or incurred by such 
Person in anticipation of the type of transaction contemplated by subclause 
(A), (B) or (C), (iii) the transfer of all of the Capital Stock of a 
Restricted Subsidiary or (iv) the issuance or transfer of directors' 
qualifying shares or a DE MINIMS number of shares required to be held by 
foreign nationals, in each case to the extent required by applicable law. The 
foregoing shall not prohibit the pledge of any shares of Capital Stock 
permitted under Section 1015.

               SECTION 1019.  LIMITATION ON DIVIDENDS AND OTHER PAYMENT 
RESTRICTIONS AFFECTING RESTRICTED SUBSIDIARIES.  The Company will not, and 
will not permit any Restricted Subsidiary to, directly or indirectly, create 
or otherwise cause or suffer to exist or become effective any encumbrance or 
restriction on the ability of any Restricted Subsidiary to (i) pay dividends, 
in cash or otherwise, or make any other distribution on or in respect of its 
Capital Stock, (ii) pay any Indebtedness owed to the Company or any other 
Restricted Subsidiary, (iii) make any loans or advances to, or Investments 
in, the Company or any other Restricted Subsidiary or (iv) transfer any of 
its properties or assets to the Company or any other Restricted Subsidiary, 
except in any such case (1) any encumbrance or restriction pursuant to an 
agreement in effect at or entered into on the Issue Date; (2) any encumbrance 
or restriction, with respect to a Person that becomes a Restricted Subsidiary 
after the Issue Date, in existence at the time such Person becomes a 
Restricted Subsidiary and not incurred in connection with, or in 
contemplation of, such Person becoming a Restricted Subsidiary (other than as 
consideration in, in contemplation of, or to provide all or any portion of 
the funds or credit support utilized to consummate, the transaction or series 
of related transactions pursuant to which such Restricted Subsidiary became a 
Restricted Subsidiary or was otherwise acquired by the Company or another 
Restricted Subsidiary); (3) any encumbrance or restriction existing under any 
agreement that extends, renews, refinances or replaces the agreements 
containing the encumbrances or restrictions in the foregoing clauses (1) and 
(2), or in this clause (3), PROVIDED that the terms and conditions of any 
such encumbrances or restrictions are (A) not materially less favorable to the


                                     73

Holders of the Securities than those under or pursuant to the agreement so 
extended, renewed, refinanced or replaced (as determined in good faith by the 
Company) and (B) with respect to any instrument relating to any Indebtedness, 
no more restrictive in any material respect than the encumbrances and 
restrictions contained in the Credit Facilities as in effect on the Issue 
Date (as determined in good faith by the Company); (4) any encumbrance or 
restriction created pursuant to an asset sale agreement, stock sale agreement 
or similar instrument pursuant to which a bona-fide Asset Sale, the proceeds 
of which are applied as provided in this Indenture, is to be consummated, so 
long as such restriction or encumbrance shall apply only to the assets 
subject to such Asset Sale and shall be effective only for a period from the 
execution and delivery of such agreement or instrument through the earlier of 
the consummation of such Asset Sale or the termination of such agreement or 
instrument; (5) customary nonassignment provisions of any lease governing any 
leasehold interest of the Company or any Restricted Subsidiaries; (6) to the

Restricted Subsidiary, any encumbrance or restriction imposed pursuant to an 
agreement that has been entered into for the sale of all or substantially all 
of the Capital Stock of such Restricted Subsidiary; and (9) purchase money 
obligations for property acquired in the ordinary course of business that 
impose restrictions of the type referred to in clause (iv) above.

               SECTION 1020.  WAIVER OF CERTAIN COVENANTS.  The Company may 
omit in any particular instance to comply with any term, provision or 
condition set forth in Sections 1008 through 1019, inclusive, if before or 
after the time for such compliance the Holders of at least a majority in 
principal amount of the Outstanding Securities, by Act of such Holders, waive 
such compliance in such instance with such term, provision or condition, but 
no such waiver shall extend to or affect such term, provision or condition 
except to the extent so expressly waived, and, until such waiver shall become 
effective, the obligations of the Company and the duties of the Trustee in 
respect of any such term, provision or condition shall remain in full force 
and effect.

               SECTION 1021.  TRUSTEE'S APPLICATION FOR INSTRUCTIONS FROM THE 
COMPANY.

               Any application by the Trustee for written instructions from 
the Company may, at the option of the Trustee, set forth in writing any 
action proposed to be taken or omitted by the Trustee under this Indenture 
and the date on and/or after which such action shall be taken or such 
omission shall be effective. The Trustee shall not be liable for any action 
taken by or omission of, the Trustee in accordance with a proposal included 
in such application on or after the date specified in such application (which 
date shall not be less than three Business Days after the date any officer of 
the Company actually receives such application, unless any such officer shall

shall have received written instructions in response to such application 
specifying the action to be taken or omitted.

                                                          REDEMPTION

               (b)  In addition, at any time and from time to time prior to 
April 15 , 2001, the Company may redeem up to 35% of the aggregate principal

with the net proceeds of such offerings at redemption price equal to 108.375% 
of the principal amount thereof, together with accrued and unpaid interest 
and Additional Amounts, if any, to the date of redemption (subject to the 
right of holders of record on Regular Record Dates to receive interest due on 
relevant Interest Payment Dates); PROVIDED that immediately after giving 
effect to each such redemption, at least 65% of the aggregate principal 
amount of the Notes (as so calculated) remain outstanding after giving effect 
to each such redemption.

               SECTION 1102.  APPLICABILITY OF ARTICLE.  Redemption of 
Securities at the election of the Company or otherwise, as permitted or

election of the Company to redeem any Securities pursuant to Section 1101 
shall be evidenced by a Board Resolution. In case of any redemption at the

of the principal amount of Securities to be redeemed and shall deliver to the 
Trustee such documentation and records as shall enable the Trustee to select 
the Securities to be redeemed pursuant to Section 1104.


                                    75

               SECTION 1104.  SELECTION BY TRUSTEE OF SECURITIES TO BE 
REDEEMED.  If less than all of the Securities are to be redeemed at any time, 
selection of Securities for redemption will be made by the Trustee in 
compliance with the requirements of the principal national securities 
exchange, if any, on which the Securities are listed or, in the absence of 
such requirements or if the Securities are not so listed, the Trustee shall 
select the Securities or portions thereof to be redeemed pro rata, lot or by 
any other method the Trustee shall deem fair and reasonable, PROVIDED that no 
such Securities of $1,000 or less in principal amount shall be redeemed in 
part.

               The Trustee shall promptly notify the Company in writing of 
the Securities selected for redemption and, in the case of any Securities 
selected for partial redemption, the principal amount thereof to be redeemed.

               For all purposes of this Indenture, unless the context 
otherwise requires, all provisions relating to redemption of Securities shall 
relate, in the case of any Security redeemed or to be redeemed only in part, 
to the portion of the principal amount of such Security which has been or is 
to be redeemed.

               SECTION 1105.  NOTICE OF REDEMPTION.  Notice of redemption 
shall be given in the manner provided for in Section 106 not less than 30 nor 
more than 60 days, prior to the Redemption Date, to each Holder of Securities 
to be redeemed.

               All notices of redemption shall identify the Securities
to be redeemed (including CUSIP or CINS number) and shall state:

               (1)  the Redemption Date,

               (2)  the Redemption Price,

               (3)  if less than all Outstanding Securities are to be 
redeemed, the identification (and, in the case of a partial redemption, the 
principal amounts) of the particular Securities to be redeemed,

               (4)  that on the Redemption Date the Redemption Price 
(together with accrued interest, if any, to the Redemption Date payable as 
provided in Section 1107) will become due and payable upon each such 
Security, or the portion thereof, to be redeemed, and that interest thereon 
will cease to accrue on and after said date, and

               (5)  the place or places where such Securities are to be 
surrendered for payment of the Redemption Price.

               Notice of redemption of Securities to be redeemed at the 
election of the Company shall be given by the Company or, at the Company's 
request, by the Trustee in the name and at the expense of the Company.

               SECTION 1106.  DEPOSIT OF REDEMPTION PRICE.  Prior to any 
Redemption Date, the Company shall deposit with the Trustee or with a Paying 
Agent (or, if the Company is acting as its own Paying Agent, segregate and 
hold in trust as provided in Section 1003) an amount of


                                     76

money sufficient to pay the Redemption Price of, and accrued interest on, all 
the Securities which are to be redeemed on that date.

               SECTION 1107.  SECURITIES PAYABLE ON REDEMPTION DATE.  Notice 
of redemption having been given as aforesaid, the Securities so to be 
redeemed shall, on the Redemption Date, become due and payable at the 
Redemption Price therein specified (together with accrued interest, if any, 
to the Redemption Date), and from and after such date (unless the Company 
shall default in the payment of the Redemption Price and accrued interest) 
such Securities shall cease to bear interest. Upon surrender of any such 
Security for redemption in accordance with said notice, such Security shall 
be paid by the Company at the Redemption Price, together with accrued 
interest, if any, to the Redemption Date; PROVIDED, HOWEVER, that 
installments of interest whose Stated Maturity is on or prior to the 
Redemption Date shall be payable to the Holders of such Securities, 
registered as such at the close of business on the relevant Record Dates 
according to their terms and the provisions of Section 309.

               If any Security called for redemption shall not be so paid 
upon surrender thereof for redemption, the principal (and premium, if any)

                             ARTICLE THIRTEEN

                         GUARANTEE OF SECURITIES

               SECTION 1301.  GUARANTEE.  Subject to the provisions of this 
Article Thirteen, the Guarantors hereby, fully, unconditionally and 
irrevocably guarantee to each Holder and to the Trustee on behalf of the 
Holders: (i) the due and punctual payment of the principal of, premium, if 
any, interest and Additional Amounts, if any, on each Security, 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 interest, if any, on the Securities, 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 
Security and this Indenture and (ii) in the case of any extension of time of 
payment or renewal of any Securities 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, PROVIDED that this Guarantee shall not be 
enforceable against the Guarantors in an amount in excess of the respective 
net worth of each Guarantor at the time that determination of such net worth 
is, under applicable law, relevant to the enforceability of such


                                     80

Guarantee. Such net worth shall include any claim of any Guarantor against 
the Company for reimbursement and any claim against any other Guarantor for 
contribution. The Guarantors hereby waive diligence, presentment, demand of 
payment, 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, 
the benefit of discussion, protest or notice with respect to any such 
Security or the debt evidenced thereby and all demands whatsoever (except as 
specified above), and covenants that this Guarantee will not be discharged as 
to any such Security except by payment in full of the principal thereof and 
interest thereon and as provided in Section 401 and Section 1202 or in the 
event of a transaction in compliance with Section 801(b). The maturity of the 
obligations guaranteed hereby may be accelerated as provided in Article Five 
for the purposes of this Article Thirteen. In the event of any declaration of 
acceleration of such obligations as provided in Article Five, such 
obligations (whether or not due and payable) shall forthwith become due and 
payable by the Guarantors for the purpose of this Article Thirteen. In 
addition, without limiting the foregoing provisions, upon the effectiveness 
of an acceleration under Article Five, the Trustee shall promptly make a 
demand for payment on the Securities under the Guarantee provided for in this 
Article Thirteen.

               If the Trustee or the Holder of any Security is required by 
any court or otherwise to return to the Company or any Guarantor, or any 
custodian, receiver, liquidator, trustee, sequestrator or other similar 
official acting in relation to the Company or such Guarantor, any amount paid 
to the Trustee or such Holder in respect of a Security, this Guarantee, to 
the extent theretofore discharged, shall be reinstated in full force and 
effect. Each of the Guarantors further agrees, to the fullest extent that it 
may lawfully do so, that, as between it, on the one hand, and the Holders and 
the Trustee, on the other hand, the maturity of the obligations guaranteed 
hereby may be accelerated as provided in Article Five hereof for the purposes 
of this Guarantee, notwithstanding any stay, injunction or other prohibition 
extant under any applicable bankruptcy law preventing such acceleration in 
respect of the obligations guaranteed hereby.

               Each of the Guarantors hereby irrevocably waives any claim or 
other rights which it may now or hereafter acquire against the Company or any 
other Guarantor that arise from the existence, payment, performance or 
enforcement of its obligations under this Guarantee and this Indenture, 
including, without limitation, any right of subrogation, reimbursement, 
exoneration, contribution, indemnification, any right to participate in any 
claim or remedy of the Holders against the Company or any Guarantor or any 
collateral which any such Holder or the Trustee on behalf of such Holder 
hereafter acquires, whether or not such claim, remedy or right arises in 
equity, or under contract, statute or common law, including. without 
limitation, the right to take or receive from the Company or a Guarantor, 
directly or indirectly, in cash or other property or by set-off or in any 
other manner, payment or security on account of such claim or other rights. 
If any amount shall be paid to a Guarantor in violation of the preceding 
sentence and the principal of, premium, if any, and accrued interest on the 
Securities shall not have been paid in full, such amount shall be deemed to 
have been paid to such Guarantor for the benefit of, and held in trust for 
the benefit of, the Holders, and shall forthwith be paid to the Trustee for 
the benefit of the Holders to be credited and applied upon the principal of, 
premium, if any, and accrued interest on the Securities. Each of the 
Guarantors acknowledges that it will receive direct and indirect benefits 
from the issuance of the Securities pursuant to this Indenture and that the 
waivers set forth in this Section 1301 are knowingly made in contemplation of 
such benefits.


                                      81

               The Guarantees set forth in this Section 1301 shall not be 
valid or become obligatory for any purpose with respect to a Security until 
the certificate of authentication on such Security shall have been signed by 
or on behalf of the Trustee.

               SECTION 1302.  OBLIGATIONS UNCONDITIONAL.  Except as provided 
in Section 1301, nothing contained in this Article Thirteen or elsewhere in 
this Indenture or in the Securities is intended to or shall impair, as among 
each of the Guarantors and the holders of the Securities, the obligations of 
each of the Guarantors, which are absolute and unconditional, upon failure by 
the Company, to pay to the holders of the Securities the principal of, 
premium, if any, interest and Additional Amounts, if any, on the Securities 
as and when the same shall become due and payable in accordance with their 
terms, or is intended to or shall affect the relative rights of the holders 
of the Securities and creditors of each of the Guarantors, nor shall anything 
herein or therein prevent the holder of any Security or the Trustee on their 
behalf from exercising all remedies otherwise permitted by applicable law 
upon default under this Indenture.

               Without limiting the foregoing, nothing contained in this 
Article Thirteen will restrict the right of the Trustee or the holders of the 
Securities to take any action to declare the Guarantee provided for herein to 
be due and payable prior to thc Stated Maturity of the Securities pursuant to 
Section 502 or to pursue any rights or remedies hereunder.

               SECTION 1303.  NOTICE TO TRUSTEE.  Each of the Guarantors 
shall give prompt written notice to the Trustee of any fact known to any one 
of the Guarantors which prohibits the making of any payment to or by the 
Trustee in respect of the Guarantees pursuant to the provisions of this 
Article Thirteen other than any agreement in effect on the date hereof.

               SECTION 1304.  THIS ARTICLE NOT TO PREVENT EVENTS OF DEFAULT.  
The failure to make a payment on account of principal of, premium, if any, 
interest or Additional Amounts, if any, on the Securities by reason of any 
provision of this Article will not be construed as preventing the occurrence 
of an Event of Default.

                               ARTICLE FOURTEEN

                         SUBORDINATION OF SECURITIES

               SECTION 1401.  SECURITIES SUBORDINATED TO SENIOR INDEBTEDNESS. 
 The Company, the Guarantors and the Trustee each covenants and agrees and 
each Holder, by its acceptance of a Security, likewise covenants and agrees 
that all Securities shall be issued subject to the provisions of this Article 
Fourteen; and each Person holding any Security, whether upon original issue 
or upon transfer, assignment or exchange thereof, accepts and agrees that 
Senior Subordinated Obligations shall, to the extent and in the manner set 
forth in this Article Fourteen, be subordinated in right of payment to the 
prior payment in full, in cash or cash equivalents, of all amounts payable 
under Senior Indebtedness, including, without limitation, the Company's 
obligations under the Credit Facilities (including any interest accruing 
subsequent to an event specified in Sections 501(7) and 501(8) of this 
Indenture, whether or not such interest is an allowed claim enforceable 
against the debtor under the United States Bankruptcy Code).



                                       82

               SECTION 1402.  NO PAYMENT ON SECURITIES IN CERTAIN 
CIRCUMSTANCES.  (a)  During the continuance of any default in the payment of 
any Senior Indebtedness beyond any applicable grace period, no payment (other 
than payments previously made pursuant to Article Twelve) or distribution of 
any assets of the Company of any kind or character shall be made by the 
Company on account of Senior Subordinated Obligations (other than such 
payments or distributions as may be agreed to by the lenders under the 
Designated Senior Indebtedness in accordance with the terms of the Designated 
Senior Indebtedness) unless and until such default shall have been cured or 
waived or shall have ceased to exist or the Senior Indebtedness with respect 
to which such payment default shall have occurred shall have been discharged 
or paid in full in cash or in any other form acceptable to the holders of 
such Senior Indebtedness (or such payment shall be duly provided for to the 
satisfaction of the holders of such Senior Indebtedness), after which the 
Company shall resume making any and all required payments in respect of 
Senior Subordinated Obligations, including any missed payments.

               (b)  During the continuance of any non-payment event of 
default with respect to any Designated Senior Indebtedness (as such event of 
default is defined in the instrument creating or evidencing such Designated 
Senior Indebtedness) pursuant to which the maturity thereof may be 
accelerated (a "NON-PAYMENT DEFAULT") and after receipt by the Trustee and 
the Company from a representative of the holders of such Designated Senior 
Indebtedness of written notice of such event of default, no payment (other 
than payments previously made pursuant to Article Twelve) or distribution of 
any assets of the Company of any kind or character (other than such payments 
or distributions as may be agreed to by the holders of such Designated Senior 
Indebtedness in accordance with the terms of the agreement governing such 
Designated Senior Indebtedness and, only to the extent acceptable to holders 
of the Securities, payment (i) in Qualified Capital Stock issued by the 
Company to pay interest on the Securities or issued in exchange for the 
Securities, (ii) in securities substantially identical to the Securities 
issued by the Company in payment of interest accrued thereon or (iii) in 
securities issued by the Company which are subordinated to the Senior 
Indebtedness at least to the same extent as the Securities and do not provide 
for the payment of principal or mandatory redemption or repurchase prior to 
the final maturity of such Designated Senior Indebtedness) shall be made by 
the Company on account of Senior Subordinated Obligations for the period 
specified below (the "PAYMENT BLOCKAGE PERIOD").

               The Payment Blockage Period shall commence upon the receipt of 
notice of the Non-payment Default by the Trustee from a Representative of the 
holders of any Designated Senior Indebtedness and shall end on the earliest 
of (i) the first date on which 179 days shall have elapsed since the receipt 
of such written notice, (ii) the date on which such Non-payment Default is 
cured, waived or ceases to exist or on which such Designated Senior 
Indebtedness is discharged or paid in full in cash or in any other manner 
acceptable to the holders of Designated Senior Indebtedness (as determined in 
accordance with the terms of the agreement governing such Designated Senior 
Indebtedness) (or the date on which payment shall be duly provided for to the 
satisfaction of the holders of such Designated Senior Indebtedness) or (iii) 
the date on which such Payment Blockage Period shall have been terminated by 
written notice to the Company or the Trustee from the Representative of, or 
the holders of at least a majority in principal amount of, the Designated 
Senior Indebtedness initiating such Payment Blockage Period, after which, in 
the case of clause (i), (ii) and (iii), the Company shall resume making any 
and all required payments in respect of Senior Subordinated Obligations, 
including any missed 



                                       83

payments. In no event will a Payment Blockage Period extend beyond 179 days 
from the date of the receipt by the Company or the Trustee of the notice 
initiating such Payment Blockage Period (such 179-day period referred to as 
the "INITIAL PERIOD"). Any number of notices of Non-payment Defaults may be 
given during the Initial Period; PROVIDED that during any 365 consecutive day 
period, only one such period during which payment of principal of, or 
interest or Additional Amounts, if any, on, the Securities may not be made 
may be commenced, and the duration of such period may not exceed 179 days. No 
Non-payment Default with respect to Designated Senior Indebtedness which 
existed or was continuing on the date of the commencement of any Payment 
Blockage Period will be, or can be, made the basis for the commencement of a 
second Payment Blockage Period, whether or not within a period of 365 
consecutive days, unless such event of default has been cured or waived for a 
period of not less than 90 consecutive days.

               (c) In the event that, notwithstanding the foregoing, any 
payment shall be received by the Trustee or any Holder when such payment is 
prohibited by Section 1402(a) or 1402(b) of this Indenture, the Trustee shall 
promptly notify the holders of Senior Indebtedness of such prohibited payment 
and such payment shall be held in trust for the benefit of, and shall be paid 
over or delivered to, the holders of Senior Indebtedness or their respective 
Representatives, or to the trustee or trustees under any indenture pursuant 
to which any of such Senior Indebtedness may have been issued, as their 
respective interests may appear, but only to the extent that, upon notice 
from the Trustee to the holders of Senior Indebtedness that such prohibited 
payment has been made, the holders of the Senior Indebtedness (or their 
Representative or Representatives or a trustee) within 30 days of receipt of 
such notice from the Trustee notify the Trustee of the amounts then due and 
owing on the Senior Indebtedness, if any, and only the amounts specified in 
such notice to the Trustee shall be paid to the holders of Senior 
Indebtedness and any excess above such amounts due and owing on Senior 
Indebtedness shall be paid to the Company.

               SECTION 1403.  PAYMENT OVER OF PROCEEDS UPON DISSOLUTION.  
ETC.  (a)  Upon any payment or distribution of assets or securities of the 
Company, of any kind or character, whether in cash, property or securities, 
upon any dissolution or winding up or total or partial liquidation or 
reorganization of the Company, whether voluntary or involuntary or in 
bankruptcy, insolvency, receivership or other proceedings, all amounts due or 
to become due upon all Senior Indebtedness (including any interest accruing 
subsequent to an event specified in Sections 501(7) and 501(8) of this 
Indenture, whether or not such interest is an allowed claim enforceable 
against the debtor under the United States Bankruptcy Code) shall first be 
paid in full, in cash or cash equivalents, before the Holders or the Trustee 
on behalf of the Holders shall be entitled to receive any payment by the 
Company on account of Senior Subordinated Obligations, or any payment to 
acquire any of the Securities for cash, property or securities, or any 
distribution with respect to the Securities of any cash, property or 
securities. Before any payment may be made by the Company of any Senior 
Subordinated Obligations upon any such dissolution, winding up, liquidation 
or reorganization, any payment or distribution of assets or securities of the 
Company of any kind or character, whether in cash, property or securities, to 
which the Holders or the Trustee on behalf of the Holders would be entitled, 
but for the provisions of this Article Fourteen, shall be made by the Company 
or by any receiver, trustee in bankruptcy, liquidating trustee, agent or 
other similar Person making such payment or distribution, or by the Holders 
or the Trustee if received by them or it, directly to the holders of Senior 
Indebtedness (PRO RATA to such holders on the basis of the respective amounts 
of Senior Indebtedness held by such holders) 



                                       84

or their Representatives, or to any trustee or trustees under any other 
indenture pursuant to which any such Senior Indebtedness may have been 
issued, as their respective interests appear, to the extent necessary to pay 
all such Senior Indebtedness in full, in cash or cash equivalents after 
giving effect to any concurrent payment, distribution or provision therefor 
to or for the holders of such Senior Indebtedness.

               (b) To the extent any payment of Senior Indebtedness (whether 
by the Company, as proceeds of security or enforcement of any right of setoff 
or otherwise) is declared to be fraudulent or preferential, set aside, or 
required to be paid to any receiver, trustee in bankruptcy, liquidating 
trustee, agent or other similar Person under any bankruptcy, insolvency, 
receivership, fraudulent conveyance or similar law, then if such payment is 
recovered by, or paid over to, such receiver, taste in bankruptcy, 
liquidating trustee, agent or other similar Person, the Senior Indebtedness 
or part thereof originally intended to be satisfied shall be deemed to be 
reinstated and outstanding as if such payment had not occurred. To the extent 
the obligation to repay any Senior Indebtedness is declared to be fraudulent, 
invalid or otherwise set aside under any bankruptcy, insolvency, 
receivership, fraudulent conveyance or similar law, then the obligation so 
declared fraudulent, invalid or otherwise set aside (and all other amounts 
that would come due with respect thereto had such obligation not been so 
affected) shall be deemed to be reinstated and outstanding as Senior 
Indebtedness for all purposes hereof as if such declaration, invalidity or 
setting aside had not occurred.

               (c) In the event that, notwithstanding the foregoing provision 
prohibiting such payment or distribution, any payment or distribution of 
assets or securities of the Company of any kind or character, whether in 
cash, property or securities, shall be received by the Trustee or any Holder 
at a time when such payment or distribution is prohibited by Section 1403(a) 
of this Indenture and before all obligations in respect of Senior 
Indebtedness are paid in full, in cash or cash equivalents, such payment or 
distribution shall be received and held in trust for the benefit of, and 
shall be paid over or delivered to, the holders of Senior Indebtedness (pro 
rata to such holders on the basis of the respective amount of Senior 
Indebtedness held by such holders) or their Representatives or to the trustee 
or trustees under any other indenture pursuant to which any such Senior 
Indebtedness may have been issued, as their respective interests appear, for 
application to the payment of Senior Indebtedness remaining unpaid until all 
such Senior Indebtedness has been paid in full, in cash or cash equivalents, 
after giving effect to any concurrent payment, distribution or provision 
therefor to or for the holders of such Senior Indebtedness.

               (d) For purposes of this Section 1403, the words "cash, 
property or securities" shall not be deemed to include (so long as the effect 
of this clause is not to cause the Securities to be treated in any case or 
proceeding or similar event described in this Section 1403 as part of the 
same class of claims as the Senior Indebtedness or any class of claims pari 
passu with, or senior to, the Senior Indebtedness for any payment or 
distribution), securities of the Company or any other corporation provided 
for by a plan of reorganization or readjustment that are subordinated, at 
least to the extent that the Securities are subordinated, to the payment of 
all Senior Indebtedness then outstanding; provided that (1) if a new 
corporation results from such reorganization or readjustment, such 
corporation assumes the Senior Indebtedness and (2) the rights of the holders 
of the Senior Indebtedness are not, without the consent of such holders, 
altered by such reorganization or readjustment. The consolidation of the 
Company with, or the 


                                       85

merger of the Company with or into, another corporation or the liquidation or 
dissolution of the Company following the sale, conveyance, transfer, lease or 
other disposition of all or substantially all of its property and assets to 
another corporation upon the terms and conditions provided in Article Eight 
of this Indenture shall not be deemed a dissolution, winding up, liquidation 
or reorganization for the purposes of this Section 1403 if such other 
corporation shall, as a part of such consolidation, merger, sale, conveyance, 
transfer, lease or other disposition, comply with the conditions stated in 
Article Eight of this Indenture.

               SECTION 1404.  SUBROGATION.  (a)  Upon the payment in full of 
all Senior Indebtedness in cash or cash equivalents, the Holders shall be 
subrogated to the rights of the holders of Senior Indebtedness to receive 
payments or distributions of cash, property or securities of the Company made 
on such Senior Indebtedness until the principal of, premium, if any, interest 
and Additional Amounts, if any, on the Securities shall be paid in full; and, 
for the purposes of such subrogation, no payments or distributions to the 
holders of the Senior Indebtedness of any cash, property or securities to 
which the Holders or the Trustee on their behalf would be entitled except for 
the provisions of this Article Fourteen, and no payment pursuant to the 
provisions of this Article Fourteen to the holders of Senior Indebtedness by 
Holders or the Trust on their behalf shall, as between the Company, their 
creditors other than holders of Senior Indebtedness, and the Holders, be 
deemed to be a payment by the Company to or on account of the Senior 
Indebtedness. It is understood that the provisions of this Article Fourteen 
are intended solely for the purpose of defining the relative rights of the 
Holders, on the one hand, and the holders of the Senior Indebtedness, on the 
other hand.

               (b) If any payment or distribution to which the Holders would 
otherwise have been entitled but for the provisions of this Article Fourteen 
shall have been applied, pursuant to the provisions of this Article Fourteen, 
to the payment of all amounts payable under Senior Indebtedness, then, and in 
such case, the Holders shall be entitled to receive from the holders of such 
Senior Indebtedness any payments or distributions received by such holders of 
Senior Indebtedness in excess of the amount required to make payment in full, 
in cash or cash equivalents, of such Senior Indebtedness of such holders.

               SECTION 1405.  OBLIGATIONS OF COMPANY UNCONDITIONAL.  (a)  
Nothing contained in this Article Fourteen or elsewhere in this Indenture or 
in the Securities is intended to or shall impair, as among the Company and 
the Holders, the obligation of the Company, which is absolute and 
unconditional, to pay to the Holders the principal of, premium, if any, 
interest and Additional Amounts, if any, on the Securities as and when the 
same shall become due and payable in accordance with their terms, or is 
intended to or shall affect the relative rights of the Holders and creditors 
of the Company other than the holders of the Senior Indebtedness, nor shall 
anything herein or therein prevent the Holders or the Trustee on their behalf 
from exercising all remedies otherwise permitted by applicable law upon 
default under this Indenture, subject to the rights, if any, under this 
Article Fourteen of the holders of the Senior Indebtedness.

               (b) Without limiting the generality of the foregoing, nothing 
contained in this Article Fourteen will restrict the right of the Trustee or 
the Holders to take any action to declare the Securities to be due and 
payable prior to their Stated Maturity pursuant to Section 502 of this 
Indenture or to pursue any rights or remedies hereunder; PROVIDED, HOWEVER, 
that all Senior Indebtedness then due and payable or thereafter declared to 
be due and payable shall first be paid 


                                       86

in full, in cash or cash equivalents, before the Holders or the Trustee are 
entitled to receive any direct or indirect payment from the Company of Senior 
Subordinated Obligations.

               SECTION 1406.  NOTICE TO TRUSTEE.  (a)  The Company shall give 
prompt written notice to the Trustee of any fact known to the Company that 
would prohibit the making of any payment to or by the Trustee in respect of 
the Securities pursuant to the provisions of this Article Fourteen. The 
Trustee shall not be charged with knowledge of the existence of any default 
or event of default with respect to any Senior Indebtedness or of any other 
facts that would prohibit the making of any payment to or by the Trustee 
unless and until the Trustee shall have received notice in writing at its 
Corporate Trust Office to that effect signed by an Officer of the Company, or 
by a holder of Senior Indebtedness, or trustee or agent therefor; and prior 
to the receipt of any such written notice, the Trustee shall, subject to 
Article Six, be entitled to assume that no such facts exist; PROVIDED that, 
if the Trustee shall not have received the notice provided for in this 
Section 1406 at least two Business Days prior to the date upon which, by the 
terms of this Indenture, any monies shall become payable for any purpose 
(including, without limitation, the payment of the principal of, premium, if 
any, interest or Additional Amounts, if any, on any Security), then, 
notwithstanding anything herein to the contrary, the Trustee shall have full 
power and authority to receive any monies from the Company and to apply the 
same to the purpose for which they were received, and shall not be affected 
by any notice to the contrary that may be received by it on or after such 
prior date except for an acceleration of the Securities prior to such 
application. Nothing contained in this Section 1406 shall limit the right of 
the holders of Senior Indebtedness to recover payments as contemplated by 
this Article Fourteen. The foregoing shall not apply if the Paying Agent is 
the Company. The Trustee shall be entitled to rely on the delivery to it of a 
written notice by a Person representing himself or itself to be a holder of 
any Senior Indebtedness (or a Trustee on behalf of, or other Representative 
of, such holder) to establish that such notice has been given by a holder of 
such Senior Indebtedness or a trustee or Representative on behalf of any such 
holder.

               (b) In the event that the Trustee determines in good faith 
that any evidence is required with respect to the right of any Person as a 
holder of Senior Indebtedness to participate in any payment or distribution 
pursuant to this Article Fourteen, 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 
Fourteen and, if such evidence is not furnished to the Trustee, the Trustee 
may defer any payment to such Person pending judicial determination as to the 
right of such Person to receive such payment.

               SECTION 1407.  RELIANCE ON JUDICIAL ORDER OR CERTIFICATE OF 
LIQUIDATING AGENT.  Upon any payment or distribution of assets or securities 
referred to in this Article Fourteen, the Trustee and the Holders shall be 
entitled to rely upon any order or decree made by any court of competent 
jurisdiction in which bankruptcy, dissolution, winding up, liquidation or 
reorganization proceedings are pending, or upon a certificate of the 
receiver, trustee in bankruptcy, liquidating trustee, agent or other similar 
Person making such payment or distribution, delivered to the Trustee or to 
the Holders for the purpose of ascertaining the persons entitled to 
participate in such distribution, the holders of the Senior Indebtedness and 
other 



                                       87

Indebtedness of the Company, the amount hereof or payable thereon, the amount 
or amounts paid or distributed thereon and all other facts pertinent thereto 
or to this Article Fourteen.

               SECTION 1408.  TRUSTEE'S RELATION TO SENIOR INDEBTEDNESS.  (a) 
 The Trustee and any Paying Agent shall be entitled to all the rights set 
forth in this Article Fourteen with respect to any Senior Indebtedness that 
may at any time be held by it in its individual or any other capacity to the 
sane extent as any other holder of Senior Indebtedness and nothing in this 
Indenture shall deprive the Trustee or any Paying Agent of any of its rights 
as such holder.

               (b) With respect to the holders of Senior Indebtedness, the 
Trustee undertakes to perform or to observe only such of its covenants and 
obligations as are specifically set forth in this Article Fourteen, and no 
implied covenants or obligations with respect to the holders of Senior 
Indebtedness shall be read into this Indenture against the Trustee. The 
Trustee shall not be deemed to owe any fiduciary duty to the holders of 
Senior indebtedness (except as provided in Sections 1402(c) and 1403(c) of 
this Indenture) and shall not be liable to any such holders if the Trustee 
shall in good faith mistakenly pay over or distribute to Holders of 
Securities or to the Company or to any other person cash, property, or 
securities to which any holders of Senior Indebtedness shall be entitled by 
virtue of this Article Fourteen or otherwise.

               SECTION 1409.  SUBORDINATION RIGHTS NOT IMPAIRED BY ACTS OR 
OMISSIONS OF THE COMPANY OR HOLDERS OF SENIOR INDEBTEDNESS.  No right of any 
present or future holders of any Senior Indebtedness to enforce subordination 
as provided in this Article Fourteen will at any time in any way be 
prejudiced or impaired by any act or failure to act on the part of the 
Company or by any act or failure to act, in good faith, by any such holder, 
or by any noncompliance by the Company with the terms of this Indenture, 
regardless of any knowledge thereof that any such holder may have or 
otherwise be charged with. The provisions of this Article Fourteen are 
intended to be for the benefit of, and shall be enforceable directly by, the 
holders of Senior Indebtedness.

               SECTION 1410.  HOLDERS AUTHORIZE TRUSTEE TO EFFECTUATE 
SUBORDINATION OF SECURITIES.  Each Holder by his acceptance of any Securities 
authorizes and expressly directs the Trustee on his behalf to take such 
action as may be necessary or appropriate to effectuate the subordination 
provided in this Article Fourteen, and appoints the Trustee his 
attorney-in-fact for such purposes, including, in the event of any 
dissolution, winding up, liquidation or reorganization of the Company 
(whether in bankruptcy, insolvency, receivership. reorganization or similar 
proceedings or upon an assignment for the benefit of creditors or otherwise) 
tending towards liquidation of the property and assets of the Company, the 
filing of a claim for the unpaid balance of its Securities in the form 
required in those proceedings. If the Trustee does not file a proper claim or 
proof of indebtedness in the form required in such proceeding at least 5 days 
before the expiration of the time to file such claim or claims, each holder 
of Senior Indebtedness is hereby authorized to file an appropriate claim for 
and on behalf of the Holders.

               SECTION 1411.  NOT TO PREVENT EVENTS OF DEFAULT.  The failure 
to make a payment on account of principal of, premium, if any, or interest on 
the Securities by reason of any provision of this Article Fourteen will not 
be construed as preventing the occurrence of an Event of Default.


                                       88

               SECTION 1412.  TRUSTEE'S COMPENSATION NOT PREJUDICED.  Nothing 
in this Article Fourteen will apply to amounts due to the Trustee pursuant to 
other sections of this Indenture.

               SECTION 1413.  NO WAIVER OF SUBORDINATION PROVISIONS.  Without 
in any way limiting the generality of Section 1409 of this Indenture, 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, without 
incurring responsibility to the Holders and without impairing or releasing 
the subordination provided in this Article Fourteen or the obligations 
hereunder of the Holders to the holders of Senior Indebtedness, do any one or 
more of the following: (a) change the manner, place or terms of payment or 
extend the time of payment of, or renew or alter, Senior Indebtedness or any 
instrument evidencing the same or any agreement under which Senior 
Indebtedness is outstanding or secured; (b) sell, exchange, release or 
otherwise deal with any property pledged, mortgaged or otherwise securing 
Senior Indebtedness; (c) release any Person liable in any manner for the 
collection of Senior Indebtedness; and (d) exercise or refrain from 
exercising any rights against the Company and any other Person.

               SECTION 1414.  PAYMENTS MAY BE PAID PRIOR TO DISSOLUTION.  
Nothing contained in this Article Fourteen or elsewhere in this Indenture 
shall prevent (i) the Company, except under the conditions described in 
Section 1402 or 1403 of this Indenture, from making payments of principal of, 
premium, if any, interest and Additional Amounts, if any, on the Securities, 
or from depositing with the Trustee any money for such payments, or (ii) the 
application by the Trustee of any money deposited with it for the purpose of 
making such payments of principal of, premium, if any, interest and 
Additional Amounts, if any, on the Securities to the holders entitled thereto 
unless, at least two Business Days prior to the date upon which such payment 
becomes due and payable, the Trustee shall have received the written notice 
provided for in Section 1402(b) of this Indenture (or there shall have been 
an acceleration of the Securities prior to such application) or in Section 
1406 of this Indenture. The Company shall give prompt written notice to the 
Trustee of any dissolution, winding up, liquidation or reorganization of the 
Company.
                                       
                                ARTICLE FIFTEEN

                          SUBORDINATION OF GUARANTEES

               SECTION 1501.  GUARANTEES SUBORDINATED TO SENIOR GUARANTOR 
INDEBTEDNESS.  The Company, the Guarantors and the Trustee each covenants and 
agrees and each Holder, by its acceptance of a Security, likewise covenants 
and agrees that the Guarantees shall be issued subject to the provisions of 
this Article Fifteen; and each Person holding any Security, whether upon 
original issue or upon transfer, assignment or exchange thereof, accepts and 
agrees that Senior Subordinated Guarantor Obligations shall, to the extent 
and in the manner set forth in this Article Fifteen, be subordinated in right 
of payment to the prior payment in full, in cash or cash equivalents, of all 
amounts payable under Senior Guarantor Indebtedness, including, without 
limitation, the obligations of the Guarantors under the Credit Facilities 
(including any interest accruing subsequent to an event specified in Sections 
501(7) and 501(8) of this Indenture, whether or not such interest is an 
allowed claim enforceable against the debtor under the United States 
Bankruptcy Code). 



                                      89


               SECTION 1502.  NO PAYMENT ON GUARANTEES OF SECURITIES IN 
CERTAIN CIRCUMSTANCES.  (a)  During the continuance of any default in the 
payment of any Senior Guarantor Indebtedness beyond any applicable grace 
period, no payment (other than payments previously made pursuant to Article 
Twelve) or distribution of any assets of any Guarantor of any kind or 
character shall be made by the Guarantors on account of Senior Subordinated 
Guarantor Obligations (other than such payments or distributions as may be 
agreed to by the lenders under the Credit Facilities in accordance with the 
terms of the Credit Facilities) unless and until such default shall have been 
cured or waived or shall have ceased to exist or the Senior Guarantor 
Indebtedness with respect to which such payment default shall have occurred 
shall have been discharged or paid in full in cash or in any other form 
acceptable to the holders of such Senior Guarantor Indebtedness (or such 
payment shall be duly provided for to the satisfaction of the holders of the 
Senior Guarantor indebtedness), after which the Guarantors shall resume 
making any and all required payments in respect of Senior Subordinated 
Guarantor Obligations, including any missed payments.

               (b) During the continuance of any non-payment event of default 
with respect to any Designated Senior Guarantor Indebtedness (as such event 
of default is defined in the instrument creating or evidencing such 
Designated Senior Guarantor Indebtedness) pursuant to which the maturity 
thereof may be accelerated (a "NON-PAYMENT DEFAULT") and after receipt by the 
Trustee and the Guarantors from a representative of the holders of such 
Designated Senior Guarantor indebtedness of written notice of such event of 
default, no payment (other than payments previously made pursuant to Article 
Twelve) or distribution of any assets of any Guarantor of any kind or 
character (other than such payments or distributions as may be agreed to by 
the holders of such Designated Senior Guarantor Indebtedness in accordance 
with the terms of the agreement governing such Designated Senior Guarantor 
indebtedness) shall be made by the Guarantors on account of Senior 
Subordinated Guarantor Obligations for the period specified below (the 
"PAYMENT BLOCKAGE PERIOD.").

               The Payment Blockage Period shall commence upon the receipt of 
notice of the Non-payment Default by the Trustee from a Representative of the 
holder of any Designated Senior Guarantor Indebtedness and shall end on the 
earliest of (i) the first date on which 179 days shall have elapsed since the 
receipt of such written notice, (ii) the date on which such Non-payment 
Default is cured, waived or ceases to exist or on which such Designated 
Senior Guarantor Indebtedness is discharged or paid in full in cash or in any 
other manner acceptable to the holders of Designated Senior Guarantor 
Indebtedness (as determined in accordance with the terms of the agreement 
governing such Designated Senior Guarantor indebtedness) (or the date on 
which payment shall be duly provided for to the satisfaction of the holders 
of such Designated Senior Guarantor Indebtedness) or (iii) the date on which 
such Payment Blockage Period shall have been terminated by written notice to 
the Guarantors or the Trustee from the Representative of, or the holders of 
at least a majority in principal amount of, the Designated Senior Guarantor 
Indebtedness initiating such Payment Blockage Period, after which, in the 
case of clause (i), (ii) and (iii), the Guarantors shall resume making any 
and all required payments in respect of Senior Subordinated Guarantor 
Obligations, including any missed payments. In no event will a Payment 
Blockage Period extend beyond 179 days from the date of the receipt by the 
Guarantors or the Trustee of the notice initiating such Payment Blockage 
Period (such 179-day period referred to as the "INITIAL PERIOD"). Any number 
of notices of Non-payment Defaults may be given during the Initial Period; 
PROVIDED that during any 365 consecutive day period, only one 


                                       90

such period during which payment of principal of, or interest on, the Notes 
may not be made may be commenced, and the duration of such period may not 
exceed 179 days. No Non-payment Default with respect to Designated Senior 
Guarantor Indebtedness which existed or was continuing on the date of the 
commencement of any Payment Blockage Period will be, or can be, made the 
basis for the commencement of a second Payment Blockage Period, whether or 
not within a period of 365 consecutive days, unless such event of default has 
been cured or waived for a period of not less than 90 consecutive days.

               In the event that, notwithstanding the foregoing, any payment 
shall be received by the Trustee or any Holder when such payment is 
prohibited by Section 1502(a) or 1502(b) of this Indenture, the Trustee shall 
promptly notify the holders of Senior Guarantor Indebtedness of such 
prohibited payment and such payment shall be held in trust for the benefit 
of, and shall be paid over or delivered to, the holders of Senior Guarantor 
Indebtedness or their respective Representatives, or to the trustee or 
trustees under any indenture pursuant to which any of such Senior Guarantor 
Indebtedness may have been issued, as their respective interest may appear, 
but only to the extent that, upon notice from the Trustee to the holders of 
Senior Guarantor Indebtedness that such prohibited payment has been made, the 
holders of the Senior Guarantor Indebtedness (or their Representative or 
Representatives or a trustee) within 30 days of receipt of such notice from 
the Trustee notify the Trustee of the amounts then due and owing on the 
Senior Guarantor Indebtedness, if any, and only the amounts specified in such 
notice to the Trustee shall be paid to the holders of Senior Guarantor 
Indebtedness and any excess above such amounts due and owing on Senior 
Guarantor Indebtedness shall be paid to United.

               SECTION 1503.  PAYMENT OVER OF PROCEEDS UPON DISSOLUTION, ETC. 
 (a)  Upon any payment or distribution of assets or securities of any of the 
Guarantors, of any kind or character, whether in cash, property or 
securities, upon any dissolution or winding up or total or partial 
liquidation or reorganization of any of the Guarantors, whether voluntary or 
involuntary or in bankruptcy, insolvency, receivership or other proceedings, 
all amounts due or to become due upon all Senior Guarantor Indebtedness 
(including any interest accruing subsequent to an event specified in Sections 
501(7) and 501(8) of this Indenture, whether or not such interest is an 
allowed claim enforceable against the debtor under the United States 
Bankruptcy Code) shall first be paid in full, in cash or cash equivalents, 
before the Holders or the Trustee on behalf of the Holders shall be entitled 
to receive any payment by such Guarantor on account of Senior Subordinated 
Guarantor Obligations, or any payment to acquire any of the Securities for 
cash, property or securities, or any distribution with respect to the 
Securities of any cash, property or securities. Before any payment may be 
made by the Guarantors of any Senior Subordinated Guarantor Obligations upon 
any such dissolution, winding up, liquidation or reorganization, any payment 
or distribution of assets or securities of any of the Guarantors of any kind 
or character, whether in cash, property or securities, to which the Holders 
or the Trustee on behalf of the Holders would be entitled, but for the 
provisions of this Article Fifteen, shall be made by any Guarantor or by any 
receiver, trustee in bankruptcy, liquidating trustee, agent or other similar 
Person making such payment or distribution, or by the Holders or the Trustee 
if received by them or it, directly to the holders of Senior Guarantor 
Indebtedness (PRO RATA to such holders on the basis of the respective amounts 
of Senior Guarantor Indebtedness held by such holders) or their 
Representatives, or to any trustee or trustees under any other indenture 
pursuant to which any such Senior Guarantor Indebtedness may have been 
issued, as their respective interests appear, to the extent necessary to pay 
all such Senior Guarantor Indebtedness in full, in cash or cash 


                                       91

equivalents after giving effect to any concurrent payment, distribution or 
provision therefor to or for the holders of such Senior Guarantor 
Indebtedness.

               (b) To the extent any payment of Senior Guarantor Indebtedness 
(whether by a Guarantor, as proceeds of security or enforcement of any right 
of setoff or otherwise) is declared to be fraudulent or preferential, set 
aside, or required to be paid to any receiver, trustee in bankruptcy, 
liquidating trustee, agent or other similar Person under any bankruptcy, 
insolvency, receivership, fraudulent conveyance or similar law, then if such 
payment is recovered by, or paid over to, such receiver, trustee in 
bankruptcy, liquidating trustee, agent or other similar Person, the Senior 
Guarantor Indebtedness or part thereof originally intended to be satisfied 
shall be deemed to be reinstated and outstanding as if such payment had not 
occurred. To the extent the obligation to repay any Senior Guarantor 
Indebtedness is declared to be fraudulent, invalid, or otherwise set aside 
under any bankruptcy, insolvency, receivership, fraudulent conveyance or 
similar law, then the obligation so declared fraudulent, invalid or otherwise 
set aside (and all other amounts that would come due with respect thereto had 
such obligation not been so affected) shall be deemed to be reinstated and 
outstanding as Senior Guarantor Indebtedness for all purposes hereof as if 
such declaration, invalidity or setting aside had not occurred.

               (c) In the event that, notwithstanding the foregoing provision 
prohibiting such payment or distribution, any payment or distribution of 
assets or securities of any of the Guarantors of any kind or character, 
whether in cash, property or securities, shall be received by the Trustee or 
any Holder at a time when such payment or distribution is prohibited by 
Section 1503(a) of this Indenture and before all obligations in respect of 
Senior Guarantor Indebtedness are paid in full, in cash or cash equivalents, 
such payment or distribution shall he received and held in trust for the 
benefit of, and shall be paid over or delivered to the holders of Senior 
Guarantor Indebtedness (PRO RATA to such holders on the basis of the 
respective amount of Senior Guarantor Indebtedness held by such holders) or 
their Representatives or to the trustee or trustees under any other indenture 
pursuant to which any such Senior Guarantor Indebtedness may have been 
issued, as their respective interests appear, for application to the payment 
of Senior Guarantor Indebtedness remaining unpaid until all such Senior 
Guarantor Indebtedness has been paid in full, in cash or cash equivalents, 
after giving effect to any concurrent payment, distribution or provision 
therefor to or for the holders of such Senior Guarantor Indebtedness.

               For purposes of this Section 1503, the words "cash, property 
or securities" shall not be deemed to include (so long as the effect of this 
clause is not to cause the Securities to be treated in any case or proceeding 
or similar event described in this Section 1503 as part of thc same class of 
claims as the Senior Guarantor Indebtedness or any class of claims PARI PASSU 
with, or senior to, the Senior Guarantor Indebtedness for any payment or 
distribution), securities of any of the Guarantors or any other corporation 
provided for by a plan of reorganization or readjustment that are 
subordinated, at least to the extent that the Securities are subordinated, to 
the payment of all Senior Guarantor Indebtedness then outstanding; PROVIDED 
that (1) if a new corporation results from such reorganization or 
readjustment, such corporation assumes the Senior Guarantor Indebtedness and 
(2) the rights of the holders of the Senior Guarantor Indebtedness are not, 
without the consent of such holders, altered by such reorganization or 
readjustment. The consolidation of any of the Guarantors with, or the merger 
of any of the Guarantors with or into, another corporation or the liquidation 
or dissolution of any of the 


                                       92

Guarantors following the sale, conveyance, transfer, lease or other 
disposition of all or substantially all of its property and assets to another 
corporation upon the terms and conditions provided in Article Eight of this 
Indenture shall not be deemed a dissolution, winding up, liquidation or 
reorganization for the purposes of this Section 1503 if such other 
corporation shall, as a part of such consolidation, merger, sale, conveyance, 
transfer, lease or other disposition, comply with the conditions stated in 
Article Eight of this Indenture.

               SECTION 1504.  SUBROGATION.  (a)  Upon the payment in full of 
all Senior Guarantor Indebtedness in cash or cash equivalents, the Holders 
shall be subrogated to the rights of the holders of Senior Guarantor 
Indebtedness to receive payments or distributions of cash, property or 
securities of United made on such Senior Guarantor Indebtedness until the 
principal of, premium, if any, and interest on the Securities shall be paid 
in full; and, for the purposes of such subrogation, no payments or 
distributions to the holders of the Senior Guarantor Indebtedness of any 
cash, property or securities to which the Holders or the Trustee on their 
behalf would be entitled except for the provisions of this Article Fifteen, 
and no payment pursuant to the provisions of this Article Fifteen to the 
holders of Senior Guarantor Indebtedness by Holders or the Trust on their 
behalf shall, as between any of the Guarantors, their creditors other than 
holders of Senior Guarantor Indebtedness, and the Holders, be deemed to be a 
payment by any of the Guarantors to or on account of the Senior Guarantor 
Indebtedness. It is understood that the provisions of this Article Fifteen 
are intended solely for the purpose of defining the relative rights of the 
Holders, on-the one hand, and the holders of the Senior Guarantor 
Indebtedness, on the other hand.

               (b) If any payment or distribution to which the Holders would 
otherwise have been entitled but for the provisions of this Article Fifteen 
shall have been applied, pursuant to the provisions of this Article Fifteen, 
to the payment of all amounts payable under Senior Guarantor Indebtedness, 
then, and in such case, the Holders shall be entitled to receive from the 
holders of such Senior Guarantor Indebtedness any payments or distributions 
received by such holders of Senior Guarantor Indebtedness in excess of the 
amount required to make payment in full, in cash or cash equivalents, of such 
Senior Guarantor Indebtedness of such holders.

               SECTION 1505.  OBLIGATIONS OF COMPANY UNCONDITIONAL.  (a)  
Nothing contained in this Article Fifteen or elsewhere in this Indenture or 
in the Securities is intended to or shall impair, as among the Guarantors and 
the Holders, the obligation of any of the Guarantors, which is absolute and 
unconditional, to pay to the Holders the principal of, premium, if any, and 
interest on the Securities as and when the same shall become due and payable 
in accordance with their terms, or is intended to or shall affect the 
relative rights of the Holders and creditors of any of the Guarantors other 
than the holders of the Senior Guarantor Indebtedness, nor shall anything 
herein or therein prevent the Holders or the Trustee on their behalf from 
exercising all remedies otherwise permitted by applicable law upon default 
under this Indenture, subject to the rights, if any, under this Article 
Fifteen of the holders of the Senior Guarantor Indebtedness.

               (b) Without limiting the generality of the foregoing, nothing 
contained in this Article Fifteen will restrict the right of the Trustee or 
the Holders to take any action to declare the Securities to be due and 
payable prior to their Stated Maturity pursuant to Section 502 of this 
Indenture or to pursue any rights or remedies hereunder; PROVIDED, HOWEVER, 
that all Senior Guarantor Indebtedness then due and payable or thereafter 
declared to be due and payable shall 


                                       93

first be paid in full, in cash or cash equivalents, before the Holders or the 
Trustee are entitled to receive any direct or indirect payment from the 
Guarantors of Senior Subordinated Guarantor Obligations.

               SECTION 1506.  NOTICE TO TRUSTEE.  (a)  Each Guarantor shall 
give prompt written notice to the Trustee of any fact known to such Guarantor 
that would prohibit the making of any payment to or by the Trustee in respect 
of the Securities pursuant to the provisions of this Article Fifteen. The 
Trustee shall not be charged with knowledge of the existence of any default 
or event of default with respect to any Senior Guarantor Indebtedness or of 
any other facts that would prohibit the making of any payment to or by the 
Trustee unless and until the Trustee shall have received notice in writing at 
its Corporate Trust Office to that effect signed by an Officer of such 
Guarantor, or by a holder of Senior Guarantor Indebtedness, or trustee or 
agent therefor; and prior to the receipt of any such written notice, the 
Trustee shall, subject to Article Six, be entitled to assume that no such 
facts exist; PROVIDED that, if the Trustee shall not have received the notice 
provided for in this Section 1506 at least two Business Days prior to the 
date upon which, by the terms of this Indenture, any monies shall become 
payable for any purpose (including, without limitation, the payment of the 
principal of, premium, if any, or interest on any Security), then, 
notwithstanding anything herein to the contrary, the Trustee shall have full 
power and authority to receive any monies from such Guarantor and to apply 
the same to the purpose for which they were received, and shall not be 
affected by any notice to the contrary that may be received by it on or after 
such prior date except for an acceleration of the Securities prior to such 
application. Nothing contained in this Section 1506 shall limit the right of 
the holders of Senior Guarantor Indebtedness to recover payments as 
contemplated by this Article Fifteen. The foregoing shall not apply if the 
Paying Agent is such Guarantor. The Trustee shall be entitled to rely on the 
delivery to it of a written notice by a Person representing himself or itself 
to be a holder of any Senior Guarantor Indebtedness (or a trustee on behalf 
of, or other Representative of, such holder) to establish that such notice 
has been given by a holder of such Senior Guarantor Indebtedness or a trustee 
or Representative on behalf of any such holder.

               (b) In the event that the Trustee determines in good faith 
that any evidence is required with respect to the right of any Person as a 
holder of Senior Guarantor Indebtedness to participate in any payment or 
distribution pursuant to this Article Fifteen, the Trustee may request such 
Person to furnish evidence to the reasonable satisfaction of the Trustee as 
to the amount of Senior Guarantor 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 Fifteen and, if such evidence is not furnished to the Trustee, 
the Trustee may defer any payment to such Person pending judicial 
determination as to the right of such Person to receive such payment.

               SECTION 1507.  RELIANCE ON JUDICIAL ORDER OR CERTIFICATE OF 
LIQUIDATING AGENT.  Upon any payment or distribution of assets or securities 
referred to in this Article Fifteen, the Trustee and the Holders shall be 
entitled to rely upon any order or decree made by any court of competent 
jurisdiction in which bankruptcy, dissolution, winding up, liquidation or 
reorganization proceedings are pending, or upon a certificate of the 
receiver, trustee in bankruptcy, liquidating trustee, agent or other similar 
Person making such payment or distribution, delivered to the Trustee or to 
the Holders for the purpose of ascertaining the persons entitled to 
participate in such distribution, the holders of the Senior Guarantor 
Indebtedness and 



                                       94

other Indebtedness of any of the Guarantors, the amount hereof or payable 
thereon, the amount or amounts paid or distributed thereon and all other 
facts pertinent thereto or to this Article Fifteen.

               SECTION 1508.  TRUSTEE'S RELATION TO SENIOR GUARANTOR 
INDEBTEDNESS.  (a)  The Trustee and any Paying Agent shall be entitled to all 
the rights set forth in this Article Fifteen with respect to any Senior 
Guarantor Indebtedness that may at any time be held by it in its individual 
or any other capacity to the same extent as any other holder of Senior 
Guarantor Indebtedness and nothing in this Indenture shall deprive the 
Trustee or any Paying Agent of any of its rights as such holder.

               (b) With respect to the holders of Senior Guarantor 
Indebtedness, thc Trustee undertakes to perform or to observe only such of 
its covenants and obligations as are specifically set forth in this Article 
Fifteen, and no implied covenants or obligations with respect to thc holders 
of Senior Guarantor Indebtedness shall be read into this Indenture against 
the Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the 
holders of Senior Guarantor Indebtedness (except as provided in Sections 
1502(c) and 1503(c) of this Indenture) and shall not be liable to any such 
holders if the Trustee shall in good faith mistakenly pay over or distribute 
to Holders of Securities or to the Guarantors or to any other person cash, 
property or securities to which any holders of Senior Guarantor Indebtedness 
shall be entitled by virtue of this Article Fifteen or otherwise.

               SECTION 1509.  SUBORDINATION RIGHTS NOT IMPAIRED BY ACTS OR 
OMISSIONS OF THE GUARANTORS OR HOLDERS OF SENIOR GUARANTOR Indebtedness. No 
right of any present or future holders of any Senior Guarantor Indebtedness 
to enforce subordination as provided in this Article Fifteen will at any time 
in any way be prejudiced or impaired by any act or failure to act on the part 
of any of the Guarantors or by any act or failure to act, in good faith, by 
any such holder, or by any noncompliance by any of the Guarantors with the 
terms of this Indenture, regardless of any knowledge thereof that any such 
holder may have or otherwise be charged with. The provisions of this Article 
Fifteen are intended to be for the benefit of, and shall be enforceable 
directly by, the holders of Senior Guarantor Indebtedness.

               SECTION 1510.  HOLDERS AUTHORIZE TRUSTEE TO EFFECTUATE 
SUBORDINATION OF GUARANTEE OF SECURITIES.  Each Holder by his acceptance of 
any Securities authorizes and expressly directs the Trustee on his behalf to 
take such action as may be necessary or appropriate to effectuate the 
subordination provided in this Article Fifteen, and appoints the Trustee his 
attorney-in-fact for such purposes, including, in the event of any 
dissolution, winding up, liquidation or reorganization of any of the 
Guarantors (whether in bankruptcy, insolvency, receivership, reorganization 
or similar proceedings or upon an assignment for the benefit of creditors or 
otherwise) tending towards liquidation of the property and assets of any of 
the Guarantors, the filing of a claim for the unpaid balance of its 
Securities in the form required in those proceedings. If the Trustee does not 
file a proper claim or proof of indebtedness in the form required in such 
proceeding at least 5 days before the expiration of the time to file such 
claim or claims, each holder of Senior Guarantor Indebtedness is hereby 
authorized to file an appropriate claim for and on behalf of the Holders.



                                       95

               SECTION 1511.  NOT TO PREVENT EVENTS OF DEFAULT.  The failure 
to make a payment on account of principal of, premium, if any, or interest on 
the Securities by reason of any provision of this Article Fifteen will not be 
construed as preventing the occurrence of an Event of Default.

               SECTION 1512.  TRUSTEE'S COMPENSATION NOT PREJUDICED.  Nothing 
in this Article Fifteen will apply to amounts due to the Trustee pursuant to 
other sections of this Indenture.

               SECTION 1513.  NO WAIVER OF SUBORDINATION PROVISIONS.  Without 
in any way limiting the generality of Section 1509 of this Indenture, the 
holders of Senior Guarantor Indebtedness may, at any time and from time to 
time, without the consent of or notice to the Trustee or the Holders, without 
incurring responsibility to the Holders and without impairing or releasing 
the subordination provided in this Article Fifteen or the obligations 
hereunder of the Holders to the holders of Senior Guarantor Indebtedness, do 
any one or more of the following: (a) change the manner, place or terms of 
payment or extend the time of payment of, or renew or alter, Senior Guarantor 
Indebtedness or any instrument evidencing the same or any agreement under 
which Senior Guarantor Indebtedness is outstanding or secured; (b) sell, 
exchange, release or otherwise deal with any property pledged, mortgaged or 
otherwise securing Senior Guarantor Indebtedness; (c) release any Person 
liable in any manner for the collection of Senior Guarantor Indebtedness; and 
(d) exercise or refrain from exercising any rights against the Guarantors and 
any other Person.

               SECTION 1514.  PAYMENTS MAY BE PAID PRIOR TO DISSOLUTION.  
Nothing contained in this Article Fifteen or elsewhere in this Indenture 
shall prevent (i) the Guarantors, except under the conditions described in 
Section 1502 or 1503 of this Indenture, from making payments of principal of, 
premium, if any, and interest on the Securities, or from depositing with the 
Trustee any money for such payments, or (ii) the application by the Trustee 
of any money deposited with it for the purpose of making such payments of 
principal of, premium, if any, and interest on the Securities pursuant to the 
Guarantees thereof to the holders entitled thereto unless, at least two 
Business Days prior to the date upon which such payment becomes due and 
payable, the Trustee shall have received the written notice provided for in 
Section 1502(b) of this Indenture (or there shall have been an acceleration 
of the Securities prior to such application) or in Section 1506 of this 
Indenture. Each Guarantor shall give prompt written notice to the Trustee of 
any dissolution, winding up, liquidation or reorganization of such Guarantor.

               The Company will pay principal, premium, if any, interest and

payment is legal tender for payment of public and private debts. However, the

if any, by its check payable in such money. The Company may (i) mail an 
interest check to a Holder's registered address (as reflected in the Security 
Register) or (ii) wire transfer the interest payment to an account located in 
the United States maintained by the payee. If a payment date is a date other 
than a Business Day at a place of payment, payment may be made at that place 
on the next succeeding day that is a Business Day and no interest shall 
accrue for the intervening period.

3.   PAYING AGENT AND REGISTRAR.

               Initially, the Trustee will act as Paying Agent and Registrar. 
The Company may change any Paying Agent or Registrar upon written notice 
thereto. The Company, United, any Subsidiary or any Affiliate of any of them 
may act as Paying Agent, Registrar and/or co-registrar.

4.   INDENTURE; LIMITATIONS.

               The Company issued the Securities under an Indenture dated as 
of April __, 1998 (the "Indenture"), among the Company, the Guarantors named 
therein and The Bank of New York, as trustee (the "Trustee"). Capitalized 
terms herein are used as defined in the Indenture unless otherwise indicated. 
The terms of the Securities include those stated in the Indenture and those 
made part of the Indenture by reference to the Trust Indenture Act. The 
Securities are subject to all such terms, and Holders are referred to the 
Indenture and the Trust Indenture Act for a statement of all such terms. To 
the extent permitted by applicable law, in the event of any inconsistency 
between the terms of this Security and the terms of the Indenture, the terms 
of the Indenture shall control.

               The Securities are general unsecured obligations of the 
Company limited to $100,000,000 aggregate principal amount at maturity, 
except for Securities authenticated and delivered upon registration of 
transfer of, or in exchange for, or in lieu of, other Securities pursuant to 
Section 303, 304, 305, 306, 906, 1010, 1016 or 1108, and, subject to 
compliance with the covenants contained in the Indenture, up to $100,000,000 
aggregate principal amount of Additional Securities having substantially 
identical terms and conditions as the Initial Securities. 



                                       6


This Security is one of the [Initial]* [Additional]**Securities referred to 
in the Indenture. The Securities include the Initial Securities, the 
Additional Securities and any Exchange Securities or Private Exchange 
Securities issued in exchange for the Initial Securities or Additional

Securities, the Exchange Securities and the Private Exchange Securities are 
treated as a single class of securities under the Indenture.

equal to ___% of the principal amount thereof, together with accrued and 
unpaid interest and Additional Amounts, if any, to the date of redemption 
(subject to the right of Holders of record on Regular Record Dates to receive 
interest due on relevant Interest Payment Dates); PROVIDED, that immediately 
after giving effect to each such redemption at least 65% of the aggregate 
principal amount of the Securities (as so calculated) remain outstanding 
after giving effect to each such redemption. On and after the redemption 
date, interest ceases to accrue on Securities or portions of Securities 
called for redemption, unless the Company defaults in the payment of the 
Redemption Price.

7.   REPURCHASE UPON A CHANGE IN CONTROL AND ASSET SALES.

               Upon the occurrence of a Change of Control, the Company is 
obligated to make an offer to purchase all Outstanding Securities at a 
redemption price of 101% of the principal amount thereof, plus accrued and 
unpaid interest and Additional Amounts, if any, to the date of purchase. Upon 
the consummation of an Asset Sale, the Company may, under certain 
circumstances, be obligated to make an offer to purchase Securities with a 
portion of the Net Cash Proceeds of such Asset Sale at a redemption price of 
100% of the principal amount thereof plus accrued and unpaid interest, if 
any, to the date of purchase.

8.   DENOMINATIONS; TRANSFER; EXCHANGE.

               The Securities are in registered form without coupons, in 
denominations of $1,000 and integral multiples of $1,000 in excess thereof. A 
Holder may register the transfer or exchange of Securities 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 or exchange of any Securities selected for 
redemption (except the unredeemed portion of any Security being redeemed in 
part). Also, the Registrar need not register the transfer or exchange of any 
Securities for a period of 15 days before a selection of Securities to be 
redeemed is made.

9.   PERSONS DEEMED OWNERS.

               A Holder may be treated as the owner of a Security for all 
purposes.

10.  UNCLAIMED MONEY.

               If money for the payment of principal, premium, if any, or 
interest remains unclaimed for two years, the Trustee and the Paying Agent 
will pay the money back to the Company at its request. After that, Holders 
entitled to the money must look to the Company for payment, unless an 
abandoned property law designates another Person, and all liability of the 
Trustee and such Paying Agent with respect to such money shall cease.

11.  DISCHARGE PRIOR TO REDEMPTION OR MATURITY.

               If the Company irrevocably deposits, or causes to be 
deposited, with the Trustee money or U.S.  Government Obligations sufficient 
to pay the then outstanding principal of, 



                                       8

premium, if any, and accrued interest on the Securities (a) to redemption or 
maturity, the Company and any Guarantor will be discharged from the Indenture 
and the Securities, except in certain circumstances for certain sections 
thereof, and (b) to the Stated Maturity, the Company and any Guarantor will 
be discharged from certain covenants set forth in the Indenture.

12.  AMENDMENT; SUPPLEMENT; WAIVER.

               Subject to certain exceptions, the Indenture or the Securities 
may be amended or supplemented with the consent of the Holders of at least a 
majority in aggregate principal amount of the Securities then outstanding, 
and any existing default or compliance with any provision may be waived with 
the consent of the Holders of a majority in aggregate principal amount of the 
Securities then outstanding. Without notice to or the consent of any Holder, 
the parties thereto may amend or supplement the Indenture or the Securities 
to, among other things, cure any ambiguity, defect or inconsistency.

13.  RESTRICTIVE COVENANTS.

               The Indenture contains certain covenants, including, without 
limitation, covenants with respect to the following matters:  (i) 
Indebtedness; (ii) Restricted Payments; (iii) issuances and sales of 
Subsidiary stock; (iv) transactions with Affiliates; (v) Liens; (vi) 
guarantees of Indebtedness by Restricted Subsidiaries; (vii) disposition of 
proceeds of Asset Sales; (viii) dividends and other payment restrictions 
affecting Restricted Subsidiaries; (ix) mergers and certain transfers of 
assets; and (x) Senior Subordinated Indebtedness. Within 90 days after the 
end of each fiscal year and within 90 days after each fiscal quarter, the 
Company must report to the Trustee on compliance with such limitations.

14.  SUCCESSOR PERSONS.

               When a successor person or other entity assumes all the 
obligations of its predecessor under the Securities and the Indenture, the 
predecessor person will be released from those obligations.

15.  REMEDIES FOR EVENTS OF DEFAULT.

               If an Event of Default, as defined in the indenture, occurs 
and is continuing, the Trustee or the Holders of not less than 25% in 
principal amount of the Securities then outstanding may declare all the 
Securities to be immediately due and payable. If a bankruptcy or insolvency 
default with respect to United, the Company or any Significant Subsidiary 
occurs and is continuing, the Securities automatically become immediately due 
and payable. Holders may not enforce the Indenture or the Securities except 
as provided in the Indenture. The Trustee may require indemnity satisfactory 
to it before it enforces the Indenture or the Securities. Subject to certain 
limitations, Holders of at least a majority in principal amount of the 
Securities then outstanding may direct the Trustee in its exercise of any 
trust or power.



                                       9

16.  SUBORDINATION.

               The payment of the Securities will, to the extent set forth in 
the Indenture, be subordinated in right of payment to the prior payment in 
full, in cash, of all Senior Indebtedness.

17.  TRUSTEE DEALINGS WITH COMPANY.

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

18.  AUTHENTICATION.

               This Security shall not be valid until the Trustee signs the 
certificate of authentication on the other side of this Security.

19.  CUSIP NUMBERS.

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

20.  GOVERNING LAW.

               This Security shall be governed by the laws of the State of 
New York applicable to contracts to be performed entirely within that state.

Attention: Corporate Trust Administration

Ladies and Gentlemen:

               This certificate is delivered to request a transfer of 
$_______ principal amount of the [      ]% Senior Subordinated Notes due 2008 
(together with the guarantees thereon, the "SECURITIES") of United Stationers 
Supply Co. (the "COMPANY").

               Upon transfer, the Securities would be registered in the name 
of the new beneficial owner as follows:

               Name:
               Address:
               Taxpayer ID Number:

               The undersigned represents and warrants to you that:

               (1) We are an institutional "accredited investor" (as defined 
in Rule 501(a)(1), (2), (3) or (7) under the Securities Act of 1933, as 
amended (the "SECURITIES ACT")), purchasing for our own account or for the 
account of an institutional "accredited investor" at least $250,000 principal 
amount of the Securities, and we are acquiring the Securities not with a view 
to, or for offer or sale in connection with, any distribution in violation of 
the Securities Act. We have such knowledge and experience in financial and 
business matters as to be capable of evaluating the merits and risks of our 
investment in the Securities and invest in or purchase securities similar to 
the Securities in the normal course of our business. We and any accounts for 
which we are acting are each able to bear the economic risk of our or its 
investment.

               (2) We understand that the Securities have not been registered 
under the Securities Act and, unless so registered, may not be sold except as 
permitted in the following sentence. We agree on our own behalf and on behalf 
of any investor account for which we are purchasing Securities to offer, sell 
or otherwise transfer such Securities prior to the date which is two years 
after the later of the date of original issue and the last date on which the 
Company or any affiliate of the Company was the owner of such Notes (or any 
predecessor thereto) (the "RESALE RESTRICTION TERMINATION DATE") only (a) to 
the Company, (b) pursuant to a registration statement that has been declared 
effective under the Securities Act, (c) in a transaction complying with the 
requirements of Rule 144A under the Securities Act ("RULE 144A"), to a person 
we reasonably believe is a "qualified institutional buyer" under Rule 144A (a 
"QIB") that purchases for its own account or for the account of a QIB and to 
whom notice is given that the transfer is being made in reliance on Rule 
144A, (d) pursuant to offers and sales that occur outside the United States

               Interest will be payable [semiannually] on each Interest 
Payment Date, commencing _____ .

               Interest on the Note will accrue from the most recent date to 
which interest has been paid or, if no interest has been paid, from the date 
of issuance.  Interest will be computed on the basis of a 360-day year of 
twelve 30-day months.

2.  SUBORDINATION.

               The Note will be subordinated indebtedness of the Company.  
Payment of the Subordinated Obligations (as defined below) will be 
subordinated in right of payment to the prior payment in full, in cash or 
cash equivalents, of all Senior Indebtedness, including, without limitation, 
the Company's obligations under the ______% Senior Subordinated Notes due 
2008.

               "Subordinated Obligations" means any principal of, premium, if 
any, or interest on the Note payable pursuant to the terms of the Note or 
upon acceleration, including any amounts received upon the exercise of rights 
of rescission or other rights of action (including claims for damages) or 
otherwise, to the extent relating to the purchase price of the Note or 
amounts corresponding to such principal, premium, if any, or interest on the 
Note.

               Upon any payment or distribution of assets or securities of 
the Company, of any kind or character, whether in cash, property or 
securities, in connection with any dissolution or winding up or total or 
partial liquidation or reorganization of the Company, whether voluntary or 
involuntary, or in bankruptcy, insolvency, receivership or other proceedings, 
all amounts due or to become due upon all Senior Indebtedness (including any 
interest accruing subsequent to an event of bankruptcy, whether or not such 
interest is an allowed claim enforceable against the debtor under the United 
States Bankruptcy Code) shall first be paid in full, in cash or cash 
equivalents, before the holders shall be entitled to receive any payment by 
the Company on account of Subordinated Obligations, or any payment to acquire 
the Note for cash, property or securities, or any distribution with respect 
to the Note of any cash, property or securities. Before any payment may be 
made by, or on behalf of, the Company on any Subordinated Obligations in 
connection with any such dissolution, winding up, liquidation or 
reorganization, any payment or distribution of assets or securities of the 
Company of any kind or character, whether in cash, property or securities, to 
which the holders would be entitled, but for the subordination provisions of 
the Note, shall be made by the Company or by any receiver, trustee in 
bankruptcy, liquidating trustee, agent or other similar person making such 
payment or distribution or by the holders if received by them, directly to 
the holders of the Senior indebtedness (PRO RATA to such holders on the basis 
of the respective amounts of Senior Indebtedness held by such holders) or 
their representatives or to any trustee or trustees under any indenture 
pursuant to which any such 



                                     D-3

Senior indebtedness may have been issued, as their respective interests 
appear, to the extent necessary to pay all such Senior Indebtedness in full, 
in cash or cash equivalents after giving effect to any concurrent payment, 
distribution or provision therefor to or for the holders of such Senior 
Indebtedness.

               No direct or indirect payment by or on behalf of the Company 
of Subordinated Obligations, whether pursuant to the terms of the Note or 
upon acceleration or otherwise, shall be made if, at the time of such 
payment, there exists an event of default, or a default (it being understood 
that as used in that sentence a "default" with respect to any Senior 
Indebtedness shall mean the happening of any event or the existence of any 
condition which, after the giving of notice or the passage of time or both, 
would constitute an event of default under such Senior Indebtedness) with 
respect to any portion of the obligations on any Senior Indebtedness, and 
such default shall not have been cured or waived or the benefits of this 
sentence waived by or on behalf of the holders of such Senior indebtedness.

               "Senior Indebtedness" means the following obligations of the 
Company: (i) any obligation with respect to the _____% Senior Subordinated 
Notes due 2008 of the Company; and (ii) all other indebtedness of the 
Company, including principal, premium and interest on such indebtedness, 
unless such indebtedness, by its terms or by the terms of any agreement or 
instrument pursuant to which such indebtedness is outstanding, is expressly 
subordinated in right of payment to any other indebtedness of the Company.

               To the extent any payment of Senior Indebtedness (whether by 
or on behalf of the Company, as proceeds of security or enforcement of any 
right of setoff or otherwise) is declared to be fraudulent or preferential, 
set aside or required to be paid to any receiver, trustee in bankruptcy, 
liquidating trustee, agent or other similar person under any bankruptcy, 
insolvency, receivership, fraudulent conveyance or similar law, then if such 
payment is recovered by, or paid over to, such receiver, trustee in 
bankruptcy, liquidating trustee, agent or other similar person, the Senior 
Indebtedness or part thereof originally intended to be satisfied shall be 
deemed to bc reinstated and outstanding as if such payment had not occurred. 
To the extent the obligation to repay any Senior Indebtedness is declared to 
be fraudulent, invalid, or otherwise set aside under any bankruptcy, 
insolvency, receivership, fraudulent conveyance or similar law, then the 
obligation so declared fraudulent, invalid or otherwise set aside (and all 
other amounts that would come due with respect thereto had such obligation 
not been affected) shall be deemed to be reinstated and outstanding as Senior 
Indebtedness for all purposes hereof as if such declaration invalidity or 
setting aside had not occurred.





                                                                       EXHIBIT E
