Company, shall sign, or one Officer shall sign and one Officer or an Assistant
Secretary of the Company (each of whom shall, in each case, have been duly
authorized by all requisite corporate actions) shall attest to, the Securities
for the Company by manual or facsimile signature.

            If an Officer or Assistant Secretary of the Company whose signature
is on a Security was an Officer or Assistant Secretary of the Company at the
time of such execution but no longer holds that office at the time the Trustee
authenticates the Security, the Security shall be valid nevertheless. Each

   37
                                      -30-


Subsidiary Guarantor shall execute the Guarantee in the manner set forth in
Section 10.06.

            A Security shall not be valid until an authorized signatory of the
Trustee manually signs the certificate of authentication on the Security. The
signature shall be conclusive evidence that the Security has been authenticated
under this Indenture.

            The Trustee shall authenticate (i) Series A Securities for original
issue in the aggregate principal amount not to exceed $200,000,000 and (ii)
Series B Securities from time to time for issue only in exchange for a like

Certificate shall specify the amount of Securities to be authenticated, the
series of Securities and the date on which the Securities are to be
authenticated. The aggregate principal amount of Securities outstanding at any
time may not exceed $200,000,000, except as provided in Section 2.07. Upon
receipt of a written order of the Company in the form of an Officers'
Certificate, the Trustee shall authenticate Securities in substitution for
Securities originally issued to reflect any name change of the Company.

            The Trustee may appoint an authenticating agent reasonably
acceptable to the Company to authenticate Securities. Unless otherwise provided
in the appointment, an authenticating agent may authenticate Securities whenever
the Trustee may do so. Each reference in this Indenture to authentication by the
Trustee includes authentication by such agent. An authenticating agent has the
same rights as the Trustee to deal with the Company and Affiliates of the
Company.

            The Securities shall be issuable only in registered form without
coupons in denominations of $1,000 and any integral multiple thereof, except as
other denominations may be necessary as a result of a pro rata redemption or
purchase of Securities required by the provisions of this Indenture and the
Securities.

            The Company, any Subsidiary Guarantor, the Trustee and any agent of
the Company, any Subsidiary Guarantor or the Trustee may treat the Person in
whose name any Security is registered as the owner of such Security for the
purpose of receiving payment of principal of and (subject to the provisions of
this Indenture and the Securities with respect to

   38
                                      -31-


record dates) interest on such Security and for all other purposes whatsoever,
whether or not such Security is overdue, and neither the Company, any Subsidiary
Guarantor, the Trustee nor any agent of the Company, any Subsidiary Guarantor or
the Trustee shall be affected by notice to the contrary.

SECTION 2.03. Registrar and Paying Agent.

            The Company shall maintain an office or agency in the Borough of
Manhattan, The City of New York, where (a) Securities may be presented or
surrendered for registration of transfer or for exchange ("Registrar"), (b)
Securities may be presented or surrendered for payment ("Paying Agent") and (c)
notices and demands in respect of the Securities and this Indenture may be
served. The Registrar shall keep a register of the Securities and of their
transfer and exchange. The Company, upon written notice to the Trustee, may have
one or more co-Registrars reasonably acceptable to the Trustee. The Company
shall appoint the Trustee as Registrar and Paying Agent until such time as the
Trustee has resigned or a successor has been appointed. Notwithstanding anything
to the contrary in this Indenture, the Paying Agent shall be, at all times, the
Trustee.

            To the extent the Company makes such payments directly to the
Holders of the Securities, the Company shall simultaneously notify the Trustee
thereof in writing.

            The Paying Agent shall comply with all applicable backup withholding
tax and information reporting requirements under the U.S. Internal Revenue Code
of 1986, as amended, and the Treasury regulations issued thereunder in respect
of any payment on, or in respect of, a Security or under a Guarantee.

            Each Paying Agent shall hold in trust for the benefit of the Holders
or the Trustee all money held by the Paying Agent for the payment of principal
of or interest on the Securities (whether such money has been paid to it by the
Company or any other obligor on the Securities), and the Company and the Paying
Agent shall notify the Trustee of any default by the Company (or any other
obligor on the Securities) in making any such payment. Money held in trust by
the Paying Agent need not be segregated except as required by law and in no
event shall the Paying Agent be liable for any interest on any money received by
it hereunder. The Company at any time may require

   39
                                      -32-


the Paying Agent to pay all money held by it to the Trustee and account for any
funds disbursed and the Trustee may at any time during the continuance of any
Event of Default, upon written request to the Paying Agent, require such Paying
Agent to pay forthwith all money so held by it to the Trustee and to account for
any funds disbursed. Upon making any payment, the Paying Agent shall have no
further liability for the money delivered to the Trustee.

SECTION 2.05. Securityholder Lists.

            The Trustee shall preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
Holders of the Securities. If the Trustee is not the Registrar, the Company
shall furnish to the Trustee before each Record Date and at such other times as
the Trustee may request in writing a list as of such date and in such form as
the Trustee may reasonably require of the names and addresses of Holders of the
Securities, which list may be conclusively relied upon by the Trustee and the
Company shall otherwise comply with TIA Section 312(a).

SECTION 2.06. Transfer and Exchange.

            Subject to the provisions of Sections 2.15 and 2.16, when Securities
are presented to the Registrar or a co-Registrar with a request to register the
transfer of such Securities or to exchange such Securities for an equal
principal amount of Securities of other authorized denominations of the same
series, the Registrar or co-Registrar shall register the transfer or make the
exchange as requested if its requirements for such transaction are met;
provided, however, that the Securities surrendered for registration of transfer
or exchange shall be duly endorsed or accompanied by a written instrument of
transfer in form satisfactory to the Company and the Registrar or co-Registrar,
duly executed by the Holder thereof or his attorney duly authorized in writing.
To permit registrations of transfers and exchanges, the Company shall execute
and the Trustee shall authenticate Securities at the Registrar's or
co-Registrar's request. No service charge shall be made for any registration of
transfer or exchange, but the Company may require payment of a sum sufficient to
cover any transfer tax or similar governmental charge payable in connection
therewith (other than any such transfer taxes or other governmental charge
payable upon exchanges (without transfer to another Person) pursuant to Section
[2.02, 2.10, 3.06, 4.15, 6.14 or 9.05,] in which event the Company shall be
responsible for

   40
                                      -33-


payment of any such taxes or charges). The Registrar or co-Registrar shall not
be required to register the transfer of or exchange of any Security (i) during a
period beginning at the opening of business 15 days before the mailing of a
notice of redemption of Securities and ending at the close of business on the
day of such mailing, (ii) selected for redemption in whole or in part pursuant
to Article Three, except the unredeemed portion of any Security being redeemed
in part and (iii) between a Record Date and the next succeeding Interest Payment
Date.

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

SECTION 2.07. Replacement Securities.

            If a mutilated Security is surrendered to the Trustee or if the
Holder of a Security claims that the Security has been lost, destroyed or
wrongfully taken, the Company shall issue and the Trustee shall authenticate
upon written notice from the Company a replacement Security if the Trustee's
requirements are met. If required by the Trustee or the Company, such Holder
must provide an indemnity bond or other indemnity, sufficient in the judgment of
both the Company and the Trustee, to protect the Company and the Trustee from
any loss which they may suffer if a Security is replaced. The Company and the
Trustee may charge such Holder for their reasonable, out-of-pocket expenses in
replacing a Security, including reasonable fees and expenses of counsel.

            Every replacement Security is an additional obligation of the
Company and is entitled to the benefit of this Indenture.

SECTION 2.08. Outstanding Securities.

            Securities outstanding at any time are all the Securities that have
been authenticated by the Trustee except those cancelled by it, those delivered
to it for cancellation and those described in this Section as not outstanding.
Subject to Section 2.09, a Security does not cease to be outstanding

   41

                                     -34-


because either of the Company or any of their Affiliates holds the Security.

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

            If on a Redemption Date or the Final Maturity Date the Paying Agent
holds U.S. Legal Tender sufficient to pay all of the principal and interest due
on the Securities payable on that date, then on and after that date such
Securities cease to be outstanding and interest on them ceases to accrue.

SECTION 2.09. Treasury Securities.

            In determining whether the Holders of the required principal amount
of Securities have concurred in any direction, waiver or consent, Securities
owned by either of the Company, any of the Subsidiary Guarantors or any of their
respective Affiliates shall be disregarded, except that, for the purposes of
determining whether the Trustee shall be protected in relying on any such
direction, waiver or consent, only Securities that a Responsible Officer of the
Trustee actually knows are so owned shall be disregarded.

            The Trustee may require an Officers' Certificate listing Securities
owned by either of the Company, a Subsidiary Guarantor or any of their
respective Affiliates.

SECTION 2.10. Temporary Securities.

            Until definitive Securities are ready for delivery, the Company may
prepare and the Trustee shall authenticate temporary Securities upon receipt of
a written order of the Company in the form of an Officers' Certificate. The
Officers' Certificate shall specify the amount of temporary Securities to be
authenticated and the date on which the temporary Securities are to be
authenticated. Temporary Securities shall be substantially in the form of
definitive Securities but may have variations that the Company consider
appropriate for temporary Securities. Without unreasonable delay, the Company
shall prepare and the Trustee shall authenticate upon receipt of a
   42

written order of the Company pursuant to Section 2.02 definitive Securities in
exchange for temporary Securities.

SECTION 2.11. Cancellation.

            The Company shall deliver to the Trustee for cancellation any
Securities that the Company may have acquired in any matter whatever. The
Registrar and the Paying Agent shall forward to the Trustee any Securities
surrendered to them for registration of transfer, exchange or payment. The
Trustee, or at the direction of the Trustee, the Registrar or the Paying Agent,
and no one else, shall cancel and, unless otherwise directed in writing by the
Company, shall dispose of all Securities surrendered for registration of
transfer, exchange, payment or cancellation. Subject to Section 2.07, the
Company may not issue new Securities to replace Securities that they had paid or
delivered to the Trustee for cancellation. If any Subsidiary Guarantor shall
acquire any of the Securities, 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
pursuant to this Section 2.11.

SECTION 2.12. Defaulted Interest.

            If the Company defaults in a payment of interest on the Securities,
it shall pay interest on overdue principal and on overdue installments of
interest (to the extent lawful) (without grace periods) on a subsequent special
record date, which date shall be at least ten Business Days prior to the payment
date, at the rate of 2% per annum in excess of the rate shown on the Securities.
The Company shall fix or cause to be fixed any such special record date and
payment date. The Company shall notify the Trustee in writing of the amount of
defaulted interest 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. At least 15 days before any such special record date, the
Company shall mail or cause to be mailed to each Holder a notice that states the
special record date, the payment date and the amount of defaulted interest to be
paid.
   43

                                     -36-


SECTION 2.13. CUSIP Number.

            The Company in issuing the Securities will use a "CUSIP" number,
and, if such CUSIP number shall be provided to the Trustee, the Trustee shall
use the CUSIP number in notices of redemption or exchange as a convenience to
Holders of the Securities; provided that any such notice may state that no
representation is made as to the correctness or accuracy of the CUSIP number
printed in the notice or on the Securities, and that reliance may be placed only
on the other identification numbers printed on the Securities. The Company shall
promptly notify the Trustee of any change in a CUSIP number.

SECTION 2.14. Deposit of Moneys.

            Prior to 11:00 a.m. New York City time on each Interest Payment Date
and the Final Maturity Date, the Company shall have either delivered by wire
transfer or check such interest or principal and interest, as the case may be,
to Holders of the Securities at such Holders' registered addresses or deposited
with the Paying Agent in immediately available funds money sufficient to make
cash payments due on such Interest Payment Date or the Final Maturity Date, as
the case may be, in a timely manner which permits the Paying Agent to remit
payment to the Holders of the Securities on such Interest Payment Date or the
Final Maturity Date, as the case may be. If payment is made directly to Holders,
the Company shall give notice to the Paying Agent and Trustee of such payment.

SECTION 2.15. Book-Entry Provisions for Global Securities.

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

            Members of, or participants in, the Depository ("Participants")
shall have no rights under this Indenture with respect to any Global Security
held on their behalf by the Depository, or the Trustee as its custodian, or
under the Global Security, and the Depository may be treated by the Company, the
Trustee and any agent of the Company or the Trustee as the absolute owner of the
Global Security for all purposes whatsoever. Notwithstanding the foregoing,
nothing herein shall prevent the Company, the Trustee or any agent of the
Company or the Trustee from giving effect to any written certification,
   44

                                     -37-


proxy or other authorization furnished by the Depository or impair, as between
the Depository and Participants, the operation of customary practices governing
the exercise of the rights of a Holder of any Security.

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

            (c) In connection with the transfer of Global Securities as an
entirety to beneficial owners pursuant to paragraph (b) of this Section 2.15,
the Global Securities shall be deemed to be surrendered to the Trustee for
cancellation, and the Company shall execute, and the Trustee shall upon written

      such names and in such authorized denominations as the Depository,
      pursuant to instructions from its direct or indirect participants or
      otherwise, shall instruct the Registrar in writing. The Registrar shall

nominee of the Depository or by the Depository or any such nominee to a
successor Depository or a nominee of such successor Depository.

            (f) Private Placement Legend. Upon the registration of 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 registration of transfer, exchange or replacement of Securities
bearing the Private Placement Legend, the Registrar shall deliver only
Securities that bear the Private Placement Legend unless, and the Trustee is
hereby authorized to deliver Securities without the Private Placement Legend if,
(i) there is delivered to the Trustee 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 or (ii) such
Security has been sold pursuant to an effective registration statement under the
Securities Act.

            (g) General. By its acceptance of any Security bearing the Private
Placement Legend, each Holder of such a Security acknowledges the restrictions

            The Registrar shall retain copies of all letters, notices and other
written communications received pursuant to
   50

                                     -43-


Section 2.15 or this Section 2.16 in accordance with its usual procedures. 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.

SECTION 2.17. Designation.

            The Indebtedness evidenced by the Securities and the Guarantees is
hereby irrevocably designated as "senior indebtedness" or such other term
denoting seniority for the purposes of any future Indebtedness of the Company
and the Subsidiary Guarantors which the Company or any Subsidiary Guarantor
makes subordinate to any senior indebtedness or such other term denoting
seniority.

                                  ARTICLE THREE

                                   REDEMPTION

SECTION 3.01. Notices to Trustee.

            If the Company elects to redeem Securities pursuant to Paragraph 5
of the Securities, it shall notify the Trustee in writing of the Redemption
Date, the Redemption Price and the principal amount of Securities to be
redeemed. The Company shall give notice of redemption to the Trustee at least 45
days but not more than 60 days before the Redemption Date (unless a shorter
notice shall be agreed to by the Trustee in writing), together with an Officers'
Certificate stating that such redemption will comply with the conditions
contained herein.

SECTION 3.02. Selection of Securities to Be Redeemed.

            If fewer than all of the Securities are to be redeemed, the Trustee
shall select the Securities to be redeemed in compliance with the requirements
of the principal national securities exchange, if any, on which the Securities
are listed or, if the Securities are not listed on a national securities
exchange, on a pro rata basis, by lot or by such method as the Trustee shall
deem fair and appropriate. If the Securities are listed on any national
securities exchange, the Company shall notify the Trustee in writing of the
requirements of such exchange in respect of any redemption. The Trustee shall
make the selection from the Securities outstanding and
   51

                                     -44-


not previously called for redemption and shall promptly notify the Company in
writing of the Securities selected for redemption and, in the case of any
Security selected for partial redemption, the principal amount thereof to be
redeemed. Securities in denominations equal to $1,000 may be redeemed only in
whole. The Trustee may select for redemption portions (equal to $1,000 or any
integral multiple thereof) of the principal of Securities that have
denominations larger than $1,000. Provisions of this Indenture that apply to
Securities called for redemption also apply to portions of Securities called for
redemption.

SECTION 3.03. Notice of Redemption.

            At least 30 days but not more than 60 days before a Redemption Date,
the Company shall mail or cause to be mailed a notice of redemption by first
class mail, postage prepaid, to each Holder whose Securities are to be redeemed.
At the Company's written request, the Trustee shall give the notice of
redemption in the name of the Company and at the expense of the Company. Each
notice for redemption shall identify the Securities to be redeemed and shall
state:

            (1) the Redemption Date;

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

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

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

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

            (6) if any Security is being redeemed in part, the portion of the
      principal amount of such Security to be redeemed and that, after the
      Redemption Date, and upon surrender of such Security, a new Security or
      Securities
   52

                                     -45-


       in aggregate principal amount equal to the unredeemed portion thereof
       will be issued;

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

            (8) the Paragraph of the Securities pursuant to which the Securities
      are to be redeemed.

SECTION 3.04. Effect of Notice of Redemption.

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

SECTION 3.05. Deposit of Redemption Price; Unclaimed Moneys.

            On or before 11:00 A.M. on the Redemption Date, the Company shall
deposit with the Paying Agent U.S. Legal Tender sufficient to pay the Redemption
Price plus accrued and unpaid interest, if any, of all Securities to be redeemed
on that date.

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

            If money on deposit with the Trustee or the Paying Agent, as the
case may be, for the payment of principal or interest remains unclaimed for two
years, the Trustee and the Paying Agent will, subject to any applicable law, pay
the money to the Company at Company's request. Thereafter, Holders of Securities
entitled to the money must look to the Company and
   53

                                     -46-


the Subsidiary Guarantors for payment unless an abandoned property law
designates another Person, and all liability of the Trustee and the Paying Agent
with respect to such money shall cease. Any money earned on funds held in trust
by the Trustee or the Paying Agent, if any, shall be remitted to the Company.

SECTION 3.06. Securities Redeemed in Part.

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

SECTION 4.01. Payment of Securities.

            The Company shall pay the principal of and interest on the
Securities in the manner provided in the Securities. An installment of principal
of or interest on the Securities shall be considered paid on the date it is due
if the Trustee or Paying Agent holds on that date U.S. Legal Tender designated
for and sufficient to pay the installment.

SECTION 4.02. Maintenance of Office or Agency.

            The Company shall maintain in the Borough of Manhattan, The City of
New York, the office or agency required under Section 2.03. The Company shall
give prompt written notice to the Trustee of the location, and any change in the
location, of such office or agency. If at any time the Company shall fail to
maintain any such required office or agency or shall fail to furnish the Trustee
with the address thereof, such presentations, surrenders, notices and demands
may be made or served at the address of the Trustee set forth in Section 11.02.
The Company hereby initially designates the corporate trust office of the
Trustee as its office or agency in the Borough of Manhattan, The City of New
York.

Lien upon the property of the Company or any of the Subsidiaries.

Subsidiary of the Company 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 the Company advantageously conducted at all
times; provided, however, that nothing in this Section 4.07(a) shall prevent the
Company or any Subsidiary of the Company from (i) discontinuing the operation or

by the Board of Directors in good faith, desirable in the conduct of the
business of the Company or of any of its Subsidiaries, (ii) making an Asset Sale
that complies with Section 4.16 or (iii) entering into a transaction permitted

            (b) The Company shall, and shall cause each of its Subsidiaries to,
keep at all times all of their properties which are of an insurable nature
insured against loss or damage with insurers believed by the Company to be
responsible to the extent that property of similar character usually is so
insured by corporations similarly situated and owning like properties in
accordance with good business practice.

            (c) The Company shall, and shall cause each of its Restricted
Subsidiaries to, keep proper books of record and account, in which full and
correct entries shall be made of all financial transactions and the assets and
business of the Company and each of its Restricted Subsidiaries, in accordance
with GAAP.

Subsidiary Guarantors has been made under the supervision of the signing
Officers with a view to determining whether the Company and the Subsidiary
Guarantors have kept, observed, performed and fulfilled their obligations under
this Indenture and further stating, as to each such Officer signing such
certificate, that to the best of his or her knowledge, the Company and the
Subsidiary Guarantors during such preceding fiscal year or fiscal quarter, as
the case may be, have kept, observed, performed and fulfilled each and every
such covenant
   58

                                     -51-


and no Default or Event of Default occurred during such period and at the date
of such certificate no Default or Event of Default has occurred and is
continuing or, if such signers do know of any Default or Event of Default, the
certificate shall describe its status with reasonable particularity. The
Officers' Certificate shall also notify the Trustee should the Company or a
Subsidiary Guarantor elect to change its fiscal year end. For purposes of this
Section 4.08(a), performance by the Company and the Subsidiary Guarantors of
their obligations under this Indenture shall be determined without regard to any
grace period or requirement of notice provided pursuant to the terms of this
Indenture.

            (b) The annual financial statements delivered pursuant to Section
4.10 shall be accompanied by a written report of the Company's independent
accountants (who shall be a firm of established national reputation) that in
conducting their audit of such financial statements nothing has come to their
attention that would lead them to believe that the Company has violated any
provisions of Article Four, Five or Six of this Indenture insofar as they relate
to accounting matters or, if any such violation has occurred, specifying the
nature and period of existence thereof, it being understood that such
accountants shall not be liable directly or indirectly to any Person for any
failure to obtain knowledge of any such violation.

            (c) The Company shall deliver to the Trustee, within ten days of
becoming aware of any Default or Event of Default in the performance of any
covenant, agreement or condition contained in this Indenture, an Officers'
Certificate specifying the Default or Event of Default and describing its status
with particularity.

SECTION 4.09. Compliance with Laws.

            The Company shall comply, and shall cause each of their Subsidiaries
to comply, with all applicable statutes, laws, rules, regulations and orders of,
and all applicable restrictions imposed by, all governmental bodies, domestic or
foreign, in respect of the conduct of its business and the ownership of its
properties, except for such noncompliance as would not, individually or in the
aggregate, have a material adverse effect on the business, condition (financial
or otherwise), properties, assets, results of operations or prospects of the
Company and their Restricted Subsidiaries taken as a whole.
   59

                                     -52-


SECTION 4.10. Reports.

            (a) Whether or not required by the rules and regulations of the
Commission, so long as any Securities are outstanding, the Company and the
Subsidiary Guarantors will file with the Commission, to the extent such filings
are accepted by the Commission, and will furnish to the Holders of Senior Notes
all quarterly and annual reports and other information, documents and reports
that would be required to be filed with the Commission pursuant to Section 13 of
the Exchange Act if the Company and the Subsidiary Guarantors were required to

will make such information available to prospective purchasers of the
Securities, securities analysts and broker-dealers who request it in writing.

            (b) For so long as any Securities remain outstanding, the Company
and the Subsidiary Guarantors will furnish to the Holders and beneficial holders
of Securities and to prospective purchasers of Securities designated by the
Holders of Transfer Restricted Securities (as defined in the Registration Rights
Agreement) and to broker dealers, upon their request, the information required
to be delivered pursuant to Rule 144A(d)(4).

SECTION 4.11. Waiver of Stay, Extension or Usury Laws.

            The Company and the Subsidiary Guarantors covenant (to the extent
that they may lawfully do so) that they shall not at any time insist upon,
plead, or in any manner whatsoever claim or take the benefit or advantage of,
any stay or extension law or any usury law or other law that would prohibit or
forgive the Company and the Subsidiary Guarantors from paying all or any portion
of the principal of and/or interest on the Securities as contemplated herein,
wherever enacted, now or at any time hereafter in force, or which may affect the
covenants or the performance of this Indenture, and (to the extent that they may
lawfully do so) the Company and the Subsidiary Guarantors hereby expressly waive
all benefit or advantage of any such law, and covenant that they 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.
   60

                                     -53-

SECTION 4.12. Limitation on Transactions with Affiliates.

            The Company shall not and shall not permit any of its Subsidiaries
to, directly or indirectly, in one transaction or a series of related
transactions, sell, lease, transfer or otherwise dispose of any of its
properties or assets to, or purchase any property or assets from or enter into
any contract, agreement, understanding, loan advance or guarantee with, or for
the benefit of, any Affiliate (each of the foregoing, an "Affiliate
Transaction"), unless (i) such Affiliate Transaction is on terms that are no
less favorable to the Company or the relevant Subsidiary than those that would
have been obtained in a comparable transaction by the Company or such Subsidiary
with an unrelated Person and (ii) the Company delivers to the Trustee (a) with
respect to any Affiliate Transaction (or series of related transactions)
involving aggregate payments in excess of $1.0 million but less than $3.0
million, an Officers' Certificate certifying that such Affiliate Transaction
complies with clause (i) above and a Secretary's Certificate which sets forth
and authenticates a resolution that has been adopted by a vote of a majority of
the Independent Directors approving such Affiliate Transaction or, if at the
time fewer than four Independent Directors are then in office, a Secretary's
Certificate which sets forth and authenticates a resolution that has been
adopted unanimously by the Company's Board of Directors and (b) with respect to
any Affiliate Transaction (or series of related transactions) involving
aggregate payments of $3.0 million or more, the certificates described in the
preceding clause (a) and an opinion as to the fairness to the Company or such
Subsidiary from a financial point of view issued by an Independent Financial
Advisor; provided, however, that (w) any employment agreement entered into by
the Company or any of its Subsidiaries in the ordinary course of business and
consistent with the past practice of the Company or such Subsidiary, (x)
transactions exclusively between or among the Company and/or its Subsidiaries,
(y) the payment of up to $1 million per fiscal year pursuant to the Servicing
Agreement and (z) payments to Parent under the Tax Sharing Agreement shall not
be deemed to be Affiliate Transactions. Notwithstanding the foregoing proviso,
the Company shall not and shall not permit any of its Subsidiaries to pay any of
its employees total annual compensation in excess of $250,000 unless (a) such
amount of compensation has been approved by a vote of a majority of the
Independent Directors, or (b) such employee's total annual compensation in
effect on the Issue Date exceeded $250,000. Any increase in total compensation
over and above
   61

                                     -54-


the amount previously approved in the case of clause (a) or the employee's total
annual compensation on the Issue Date in the case of clause (b), shall be
approved by a vote of a majority of the Independent Directors, other than an
increase at the end of any year in the amount of total compensation by an amount
equal to the Index Amount for such year.

SECTION 4.13. Independent Directors.

            (a) The Company's Board of Directors shall at all times have at
least four Independent Directors; provided, however, that notwithstanding the
foregoing, if an Independent Director resigns, dies or is terminated for any
reason and the remaining number of Independent Directors is less than four, a
replacement for that Independent Director shall be elected as promptly as
practicable, but in no event later than the date that is six months from the
date of the resignation, death or termination of the Independent Director being
replaced.

            (b) After the Issue Date, the election of any new Independent
Directors must be approved by a unanimous vote of the Independent Directors then
in office, provided that only a majority vote of the Independent Directors is
required if at the time there are four or more Independent Directors in office.
The Independent Directors shall approve such new Independent Director unless the
Independent Directors determine that such person does not satisfy the
requirements to serve as an Independent Director under this Indenture or such
person is not able or willing to perform the obligations of the Independent
Directors under this Indenture.

            (c) If at any time the number of Independent Directors then in
office is less than two, then until such time as the number of Independent
Directors exceeds two the Company shall not, and shall not permit any of its
Subsidiaries to, engage in any transaction that this Indenture requires be
approved by a vote of the Independent Directors.

            (d) Any transaction that this Indenture requires be approved by a
vote of the Independent Directors shall be evidenced by a Secretary's
Certificate setting forth a resolution adopted by at least the requisite number
of Independent Directors, a copy of which shall be delivered to the Trustee,
which resolution shall state that the transaction being approved is not unfair
to the holders of the Securities. The failure to comply with this clause (d)
shall have the effect of the


                                     -55-
   62

Company failing to comply with the requirement in this Indenture to obtain a
vote of the Independent Directors.

SECTION 4.14. Limitations on Restrictions on Distributions from Subsidiaries.

            The Company shall not, and shall not permit any of its Subsidiaries
to, create or otherwise cause or suffer to exist or become effective any
consensual Payment Restriction with respect to any of its Subsidiaries, except
for (a) any such Payment Restriction in effect on the Issue Date under the New
Bank Credit Facility or any similar Payment Restriction under any similar bank
credit facility or any replacement thereof, provided that such similar Payment
Restriction is no more restrictive than the Payment Restriction in effect on the
Issue Date under the New Bank Credit Facility, (b) any such Payment Restriction
under any agreement evidencing any Acquired Indebtedness that was permitted to
be incurred pursuant to this Indenture, provided that such Payment Restriction
only applies to assets that were subject to such restriction and encumbrances
prior to the acquisition of such assets by the Company or its Subsidiaries and
(c) any such Payment Restriction arising in connection with Refinancing
Indebtedness; provided that any such Payment Restrictions that arise under such
Refinancing Indebtedness are not, taken as a whole, more restrictive than those
under the agreement creating or evidencing the Indebtedness being refunded or
refinanced.

SECTION 4.15. Limitation on Liens.

            The Company shall not, and shall not cause or permit any of the
Subsidiaries to, directly or indirectly create, incur, assume or suffer to exist
any Lien on any property or asset now owned or hereafter acquired, or on any
income or profits therefrom, or assign or convey any right to receive income
therefrom, except Permitted Liens, unless prior thereto or simultaneously
therewith, the Securities are equally and ratably secured; provided that if such
Indebtedness is Subordinated Indebtedness the Lien securing such Indebtedness
shall be junior to the Lien securing the Securities.

SECTION 4.16. Limitation on Asset Sales.

            (a) The Company shall not, and shall not permit any of its
Subsidiaries to, consummate any Asset Sale unless (i) the Company or its
Subsidiaries receive consideration at the time of such Asset Sale at least equal
to the Fair Market
   63

                                     -56-


Value of the assets included in such Asset Sale, provided the aggregate Fair
Market Value of the consideration received from an Asset Sale that is not in the
form of cash or Cash Equivalents shall not, when aggregated with the Fair Market
Value of all other non-cash or consideration received by the Company and its
Subsidiaries from all previous Asset Sales since the Issue Date that has not,
prior to such date, been converted into cash or Cash Equivalents, exceed 5% of
the Consolidated Tangible Assets of the Company at the time of such Asset Sale
under consideration and provided, further, that with respect to any Asset Sale
to Affiliates the Company shall receive consideration consisting of not less
than 85% cash or Cash Equivalents and (ii) the Company delivers to the Trustee
an Officers' Certificate certifying that such Asset Sale complies with clause
(i). The amount (without duplication) of any Indebtedness (other than
Subordinated Indebtedness) of the Company or such Subsidiary that is expressly
assumed by the transferee in such Asset Sale and with respect to which the
Company or such Subsidiary, as the case may be, is unconditionally released by
the holder of such Indebtedness, shall be deemed to be cash or Cash Equivalents
for purposes of clause (ii) and shall also be deemed to constitute a repayment
of and a permanent reduction in, the amount of such Indebtedness for purposes of
the following paragraph (b). If at any time any non-cash consideration received
by the Company or any Subsidiary of the Company, as the case may be, in
connection with any Asset Sale is converted into or sold or otherwise disposed
of for cash (other than interest received with respect to any such non-cash
consideration), then the date of such conversion or disposition shall be deemed
to constitute the date of an Asset Sale hereunder and the Net Available Proceeds
thereof shall be applied in accordance with this Section 4.16. A transfer of
assets by the Company to a Subsidiary or by a Subsidiary to the Company or to a
Subsidiary will not be deemed to be an Asset Sale and a transfer of assets that
constitutes a Restricted Investment and that is permitted under Section 4.03
will not be deemed to be an Asset Sale.

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


   64
                                     -57-


assets of the Company or its Subsidiaries deemed to be sold shall be deemed to
be Net Available Proceeds for purposes of this covenant.

            (b) If the Company or any Subsidiary engages in an Asset Sale, the
Company or such Subsidiary may either, no later than 270 days after such Asset
Sale, (i) apply all or any of the Net Available Proceeds therefrom to repay
amounts outstanding under the New Bank Credit Facility or any other Indebtedness
(other than Subordinated Indebtedness) of the Company or any Subsidiary;
provided, in each case, that the related loan commitment (if any) is thereby
permanently reduced by the amount of such Indebtedness so repaid or (ii) invest
all or any part of the Net Available Proceeds thereof in properties and assets
that replace the properties or assets that were the subject of such Asset Sale
or in other properties or assets that will be used in the business of the
Company and its Subsidiaries as it existed on the Issue Date. The amount of such
Net Available Proceeds not applied or invested as provided in this paragraph
will constitute "Excess Proceeds."


            (c) When the aggregate amount of Excess Proceeds equals or exceeds
$5.0 million, the Company will be required to make an offer to purchase, from
all Holders of the Senior Notes, an aggregate principal amount of Senior Notes
equal to such Excess Proceeds as follows:

            (i) The Company will make an offer to purchase (a "Net Proceeds
      Offer") from all Holders of the Securities the maximum principal amount
      (expressed as a multiple of $1,000) of Securities that may be purchased
      out of the amount (the "Payment Amount") of such Excess Proceeds.

            (ii) The offer prices for the Securities will be payable in cash in
      an amount equal to 100% of the principal amount of the Securities tendered
      pursuant to a Net Proceeds Offer, plus accrued and unpaid interest and
      Liquidated Damages, if any, to the date such Net Proceeds Offer is
      consummated (the "Offered Price"). To the extent that the aggregated
      Offered Price of Securities tendered pursuant to a Net Proceeds Offer is
      less than the Payment Amount relating thereto (such shortfall constituting
      a "Net Proceeds Deficiency"), the Company may use such Net Proceeds
      Deficiency, or a portion thereof, for general corporate purposes, subject
      to the limitations of Section 4.03.
   65

                                     -58-


            (iii) If the aggregate Offered Price of Securities validly tendered
      and not withdrawn by Holders thereof exceeds the Payment Amount,
      Securities to be purchased will be selected on a pro rata basis.

            (iv) Upon completion of such Net Proceeds Offer, the amount of
      Excess Proceeds remaining shall be zero.

            The Company will not permit any Subsidiary to enter into or suffer
to exist any agreement that would place any restriction of any kind (other than
pursuant to law or regulation) on the ability of the Company to make a Net
Proceeds Offer following any Asset Sale. The Company will comply with Rule 14e-l
under the Exchange Act and any other securities laws and regulations thereunder,
if applicable, in the event that an Asset Sale occurs and the Company is
required to purchase Senior Notes as described above.

SECTION 4.17. Restrictions on Sale of Capital Stock of Subsidiaries.

            The Company shall not, and shall not permit any Subsidiary to, sell
or otherwise dispose of any of the Capital Stock of any Subsidiary unless: (i)
(a) the Company shall retain ownership, directly or indirectly, of more than 50%
of the Common Equity of such Subsidiary or (b) all of the Capital Stock of such
Subsidiary shall be sold or otherwise disposed of; and (ii) the Net Available
Proceeds from any such sale or disposition are applied or otherwise treated in a
manner consistent with the provisions described in Section 4.16.

SECTION 4.18. Restrictions on Sale and Leaseback Transactions.

            The Company will not, and will not permit any of its Subsidiaries
to, directly or indirectly, enter into, renew or extend any Sale and Leaseback
Transaction unless: (i) the Company or such Subsidiary would be entitled, under
Section 4.04 and Section 4.19 to incur Indebtedness in an amount equal to the
Attributable Indebtedness with respect to such Sale and Leaseback Transaction,
(ii) such Sale and Leaseback Transaction would not result in a violation of
Section 4.18; and (iii) the Net Available Proceeds from any such Sale and
Leaseback Transaction are applied in a manner consistent with the provisions
described in Section 4.18.
   66

                                     -59-


SECTION 4.19. Additional Subsidiary Guarantees.

            If the Company or any of its Subsidiaries shall acquire or create
another Subsidiary, then, unless such newly acquired or created Subsidiary will
be required to execute a Subsidiary Guarantee, in accordance with the terms of
this Indenture, unless it has been been designated as an Unrestricted
Subsidiary.

SECTION 4.20. Change of Control.

            (a) Upon the occurrence of a Change of Control, the Company shall be
obligated to make an offer to all Holders of Securities to purchase (a "Change
of Control Offer") all outstanding Securities and will purchase, on a business
day not more than 60 days nor less than 30 days after the occurrence of the
Change of Control (such purchase date being the "change of Control Purchase
Date"), all Securities properly tendered pursuant to such offer to purchase for
a cash price (the "Change of Control Purchase Price") equal to 101% of the
principal amount of the Senior notes, plus accrued and unpaid interest, if any,
to the Change of Control Purchase Date.

            (b) In order to effect a Change of Control Offer, the Company shall
within 30 days after the occurrence of the Change of Control mail the Trustee
who shall mail to each Holder of Securities (with a copy to the Trustee), a copy
of the Change of Control Offer. The Change of Control Offer shall remain open
from the time of mailing for at least 20 Business Days and until the close of
business on the third Business Day prior to the Change of Control Purchase Date.
The notice, which shall govern the terms of the Change of Control Offer, shall
include such disclosures as are required by law and shall state:

            (i) the date of such Change of Control and, briefly, the events
      causing such Change of Control;

            (ii) that the Change of Control Offer is being made pursuant to this
      Section 4.20 and that all Securities tendered in the Change of Control
      Offer will be accepted for payment;

            (iii) the Change of Control Purchase Price for each Security, the
      date on which the Securities shall be purchased (such purchase date being
      the "Change of Control Purchase Date"), the last date on which the Change
      of
   67

                                     -60-


      Control Purchase Notice must be given, the date on which the Change of
      Control Offer expires and the names and addresses of any Paying Agent and
      the offices or agencies maintained by the Company for such purpose in The

            (iv) that any Security not tendered for payment will continue to
      accrue interest in accordance with the terms thereof;

            (v) that, unless the Company shall default in the payment of the
      Change of Control Purchase Price, any Security accepted for payment
      pursuant to the Change of Control Offer shall cease to accrue interest
      after the Change of Control Purchase Date;

            (vi) that Holders electing to have Securities purchased pursuant to
      a Change of Control Offer will be required to surrender their Securities

      Security certificate number (if any) and a statement that such Holder is
      withdrawing his election to have such Securities purchased;

            (viii) that Holders whose Securities are purchased only in part will

SECTION 4.22. Special Offer upon Failure to Consummate Capital Improvement
              Program.

            (a) If the Capital Improvement Plan is abandoned by the Company
because its completion is no longer possible, practical or economical, as
determined by the Board of Directors of the Company and evidenced by a Board
Resolution, or not completed on or before August 31, 1999, then, 30 days after
the earlier of (i) written notice from an Officer of the Company, and a
certified copy of the Board Resolution, is received by the Trustee regarding the
abandonment of the Capital Improvement Plan or (ii) August 31, 1999 (as the case
may be, the "Special Offer Notice Date"), the Company will be obligated to make
an offer to purchase (the "Special Offer") an aggregate principal amount of
Securities equal to $34.8 million less any amount previously released from the
Escrow Funds to be applied to the Capital Improvement Plan (the "Special Offer
Amount") for a purchase price of 100% of the principal amount of the
   71

                                     -64-


Securities, plus accrued and unpaid interest to the date of purchase (the
"Special Offer Purchase Date").

            (b) On the Special Offer Notice Date, the Company shall mail to each
Holder of Securities at such Holder's registered address a notice stating: (i)
that the Capital Improvement Plan has been abandoned or not completed and that
the Company is offering to purchase the specified aggregate principal amount of
Securities at a purchase price in cash equal to 100% of the aggregate principal
amount thereof, plus accrued and unpaid interest to the Special Offer Purchase
Date, which shall be a business day, specified in such notice, that is not
earlier than 30 days or later than 60 days from the date such notice is mailed,
(ii) the amount of accrued and unpaid interest as of the Special Offer Purchase
Date, (iii) that any Security not tendered will continue to accrue interest,
(iv) that, unless the Company defaults in the payment of the purchase price for
the Securities payable pursuant to the Special Offer, any Securities accepted
for payment pursuant to the Special Offer shall cease to accrue interest on and
after the Special Offer Purchase Date, (v) the procedures, consistent with this
Indenture, to be followed by a holder of Securities in order to accept a Special
Offer or to withdraw such acceptance, and (vi) such other information as may be
required by this Indenture and applicable laws and regulations.

            (c) On the Special Offer Purchase Date, the Company will (i) accept
for payment the aggregate principal amount of Securities covered by the Special
Offer or such lesser amount as is tendered pursuant to the Special Offer and
(ii) deliver or cause to be delivered to the Trustee all Securities tendered
pursuant to the Special Offer and accepted for payment and the Special Offer
Amount of the Escrow Funds will be applied to consummate the Special Offer. If
less than all Securities tendered pursuant to the Special Offer are accepted for
payment by the Company for any reason consistent with this Indenture, selection
of the Securities to be purchased by the Company shall be in compliance with the
requirements of the principal national securities exchange, if any, on which the
Securities are listed or, if the Securities are not so listed, on a pro rata
basis, by lot or by such method as the Trustee shall deem fair and appropriate;
provided that Securities accepted for payment in part shall only be purchased in
integral multiplies of $1,000. The Paying Agent shall promptly mail to each
holder of Securities or portions thereof accepted for payment an amount equal to
the purchase price for such Securities including any accrued and unpaid interest
thereon, and the Trustee
   72

                                     -65-


shall promptly authenticate and mail to such Holder of Securities accepted for
payment in part a new Security equal in principal amount to any unpurchased
portion of the Securities, and any Security not accepted for payment in whole or
in part for any reason consistent with this Indenture shall be promptly returned
to the Holder of such Security. On and after the Special Offer Purchase Date,
interest will cease to accrue on the Securities or portions thereof accepted for
payment, unless the Company defaults in the payment of the purchase price
therefor. The Company will announce the results of the Special Offer to Holders
of the Securities on or as soon as practicable after the Special Offer Purchase
Date.

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

                              SUCCESSOR CORPORATION

SECTION 5.01. Mergers, Consolidations and Sale of Assets.

            (a) The Company shall not, in a single transaction or a series of
related transactions, (i) consolidate or merge with or into (other than a merger
with a Wholly-Owned Subsidiary solely for the purpose of changing the Company's
jurisdiction of incorporation to one of the States of the United States), or
sell, lease, convey or otherwise dispose of or assign all or substantially all
of the assets of the Company and its Subsidiaries (taken as a whole), or assign
any of its obligations under the Securities or this Indenture, to any Person or
(ii) adopt a Plan of Liquidation unless, in either case: (a) the Person formed
by or surviving such consolidation or merger (if other than the Company) or to
which such sale, lease, conveyance or other disposition or assignment shall be
made (or, in the case of a Plan of Liquidation, any Person to which assets are
transferred) (collectively, the "Successor") is a corporation organized and
existing under the laws of the United States or any State thereof or the
District of Columbia and the Successor assumes by supplemental indenture in a
form satisfactory to the Trustee all of the obligations of the Company under the
Securities and this Indenture; (b) immediately prior to and immediately after
giving effect to such
   73

                                     -66-


transaction and the assumption of the obligations as set forth in clause (a)
above and the incurrence of any Indebtedness to be incurred in connection
therewith, no Default or Event of Default shall have occurred and be continuing;
(c) immediately after and giving effect to such transaction and the assumption
of the obligations set forth in clause (a) above and the incurrence of any
Indebtedness to be incurred in connection therewith, and the use of any net
proceeds therefrom on a pro forma basis, (1) the Consolidated Net Worth of the
Company or the Successor, as the case may be, would be at least equal to the
Consolidated Net Worth of the Company immediately prior to such transaction and
(2) the Company or the Successor, as the case may be, could incur at least $1.00
of additional Indebtedness pursuant to the Consolidated Fixed Charge Coverage
Ratio test set forth in Section 4.04(a); and (d) each Subsidiary Guarantor,
unless it is the other party to the transactions described above, shall have by
amendment to its Guarantee confirmed that its Guarantee of the Securities shall
apply to the obligations of the Company or the Successor under the Securities
and this Indenture. For purposes of this Section 5.01, any Indebtedness of the
Successor which was not Indebtedness of the Company immediately prior to the
transaction shall be deemed to have been incurred in connection with such
transaction.

            The Company shall give the Trustee an Officer's Certificate and if a
supplemental indenture is required, a legal opinion that the merger,
consolidation, or sale of assets contemplated in this Section 5.01 complies with
this Indenture.

SECTION 5.02. Successor Corporation Substituted.

            Upon any such consolidation, merger, conveyance, lease or transfer
in accordance with the foregoing, the Successor formed by such consolidation or
into which the Company is merged or to which such conveyance, lease or transfer
is made will succeed to, and be substituted for, and may exercise every right
and power of, the Company entering into or making such consolidation, merger,
conveyance, lease or transfer under this Indenture with the same effect as if
such Successor had been named as the Company herein, and thereafter (except in
the case of a sale, assignment, transfer, lease, conveyance or other
disposition) the predecessor corporation will be relieved of all further
obligations and covenants under this Indenture, the Securities and the
Registration Rights Agreement. For all purposes of this Indenture and the
Securities (including the provisions of this Article Five and Article Four),
Subsidiaries of any Successor will, upon such transaction or series of
   74

                                     -67-


transactions, become Subsidiaries or Unrestricted Subsidiaries as provided
pursuant to definition of Unrestricted Subsidiary and all Indebtedness, and all
Liens on property or assets, of the Company and the Subsidiaries immediately
prior to such transaction or series of transactions will be deemed to have been
incurred upon such transaction or series of transactions.

      satisfied, stayed, annulled or rescinded within 60 days of being entered;
      or

            (viii) except as permitted by this Indenture, any Subsidiary

      a voluntary case or proceeding under any Bankruptcy Law with respect to
      itself, (c) consents to the entry of a judgment, decree or order for

       judgment, decree or order shall remain unstayed and in effect for a
       period of 60 consecutive days; or

            For purposes of this Article Six: the term "Custodian" means any
receiver, interim receiver, receiver and manager, trustee, assignee, liquidator,
sequestrator or similar official charged with maintaining possession or control
over property for one or more creditors, whether under any Bankruptcy Law or
otherwise.

SECTION 6.02. Acceleration.

            If an Event of Default (other than an Event of Default specified in
clause (x) or (xi)) shall have occurred and be continuing under this Indenture,
the Trustee, by written notice to the Company, or the Holders of at least 25% in
the aggregate principal amount of the Securities then outstanding by written
notice to the Company and Trustee may declare all amounts owing under the
Securities to be due and payable immediately. Upon such declaration of
acceleration, the aggregate principal amount of, premium, if any, and interest
on the outstanding Securities shall immediately become due and payable. If an
Event of Default specified in clause (x) or (xi) above with respect to Company
occurs and is continuing, then the principal amount of, premium, if any, and
accrued interest on, all the Securities shall ipso facto become and be
immediately due and payable without any declaration or other act on the part of
the Trustee or any Holder of Securities.

SECTION 6.03. Other Remedies.

            If an Event of Default occurs and is continuing, the Trustee may
(and, at the direction of the Holders of a majority of the aggregate principal
amount of outstanding Securities, subject to Section 7.02(f), shall) pursue any
available remedy by proceeding at law or in equity to collect the payment of
principal of or interest on the Securities or to enforce the performance of any
provision of the Securities, this Indenture, or the Guarantees.

            The Trustee may maintain a proceeding even if it does not possess
any of the Securities or does not produce any of them in the proceeding. A delay
or omission by the Trustee, or any Securityholder in exercising any right or
remedy accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. No remedy is
exclusive of any other remedy. All
   77

                                     -70-


available remedies are cumulative to the extent permitted by law.

SECTION 6.04. Waiver of Past Defaults.

            Subject to Sections 6.07 and 9.02, the Holders of not less than a
majority in aggregate principal amount of the outstanding Securities may on
behalf of the Holders of all the Securities waive any past Defaults under this
Indenture, except a Default in the payment of the principal of, premium, if any,
or interest on any Security. The Company shall deliver to the Trustee an
Officers' Certificate stating that the requisite percentage of Holders have
consented to such waiver and attaching copies of such consents upon which the
Trustee may conclusively rely.

SECTION 6.05. Control by Majority.

            The Holders of not less than a majority in principal amount of the
outstanding Securities may direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or exercising any trust or
power conferred on it hereunder. Subject to Section 7.01, however, the Trustee
may refuse to follow any direction that the Trustee reasonably believes
conflicts with any law or this Indenture, that the Trustee determines may be
unduly prejudicial to the rights of another Holder of Securities, or that may
involve the Trustee in personal liability; provided that the Trustee may take
any other action deemed proper by it which is not inconsistent with such
direction; and provided further, that this provision shall not affect the rights
of the Trustee set forth in Section 7.01(d).

            In the event the Trustee takes any action or follows any direction
pursuant to this Indenture, the Trustee shall be entitled to indemnification
from the Company satisfactory to it in its sole discretion against any loss,
liability, cost or expense caused by taking such action or following such
direction.

SECTION 6.06. Limitation on Suits.

            A Holder of Securities may not pursue any remedy with respect to
this Indenture, the Guarantees or the Securities unless:
   78

                                     -71-


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

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

            (3) such Holder or Holders offer and, if requested, provide to the
      Trustee indemnity or security satisfactory to the Trustee against any
      loss, liability or expense;

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

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

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

SECTION 6.07. Rights of Holders to Receive Payment.

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

SECTION 6.08. Collection Suit by Trustee.

            If an Event of Default specified in clause (i) or (ii) of Section
6.01 occurs and is continuing, the Trustee may recover judgment in its own name
and as trustee of an express trust against the Company or any other obligor on
the Securities for the whole amount of principal, accrued interest and other
amounts remaining unpaid, together with interest on overdue principal and, to
the extent that payment of such interest is lawful, interest on overdue
installments of interest, in each case at the rate per annum borne by the
Securities and
   79

                                     -72-


such further amount as shall be sufficient to cover the costs and expenses of
collection, including the compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel.

SECTION 6.09. Trustee May File Proofs of Claim.

            The Trustee may file such proofs of claim and other papers or
documents as may be necessary or advisable in order to have the claims of the
Trustee (including any claim for the compensation, expenses, legal fees,
disbursements and advances of the Trustee, and its agents, nominees, custodians
and counsel, and any other amounts due to the Trustee under Section 7.07) and
the Holders of Securities allowed in any judicial proceedings relating to the
Company and the Subsidiary Guarantors, their creditors or their property and
shall be entitled and empowered to collect and receive any monies or other
property payable or deliverable on any such claims and to distribute the same,
and any Custodian in any such judicial proceedings is hereby authorized by each
Holder of Securities 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
of Securities, to pay to the Trustee any amount due to it for the compensation,
expenses, legal fees, disbursements and advances of the Trustee and its agents,
nominees, custodians and counsel, and any other amounts due the Trustee under
Section 7.07. Nothing herein contained shall be deemed to authorize the Trustee
to authorize or consent to or accept or adopt on behalf of any Holder of
Securities any plan of reorganization, arrangement, adjustment or composition
affecting the Securities or the rights of any Holder thereof, or to authorize
the Trustee to vote in respect of the claim of any Holder of Securities in any
such proceeding.

SECTION 6.10. Priorities.

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

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

            Second: if the Holders of Securities are forced to proceed against
      the Company or a Subsidiary Guarantor or any other obligor on the
      Securities directly without the Trustee, to such Holders for their
      collection costs;
   80

                                     -73-


            Third: to Holders of Securities for amounts due and unpaid on the
      Securities for interest, ratably, without preference or priority of any
      kind, according to the amounts due and payable on the Securities for
      interest;

            Fourth: to Holders of Securities for amounts due and unpaid on the
      Securities for principal, ratably, without preference or priority of any
      kind, according to amounts due and payable on the Securities for
      principal; and

            Fifth: to the Company or the Subsidiary Guarantors, as their
      respective interests may appear.

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

SECTION 6.11. Undertaking for Costs.

            In any suit for the enforcement of any right or remedy under this
Indenture or in any suit against the Trustee for any action taken or omitted by
it as Trustee, a court in its discretion may require the filing by any party
litigant in the suit of an undertaking to pay the costs of the suit, and the
court in its discretion may assess reasonable costs, including reasonable
attorneys' fees 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 6.11 does not apply to a suit by the Trustee, a suit by a
Holder of Securities pursuant to Section 6.07, or a suit by a Holder or Holders
of more than 10% in principal amount of the outstanding Securities.

SECTION 6.12. Rights and Remedies Cumulative.

            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 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.
   81

                                     -74-


SECTION 6.13. 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 VI 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.

                                     TRUSTEE

SECTION 7.01. Duties of Trustee.

              (a) If an Event of Default actually known to a Responsible Officer
(except in the case of Sections 7.05 and 7.06, as used in this Article Seven,
"Trustee" shall mean the Trustee in its capacity as Trustee under this
Indenture) has occurred and is continuing, the Trustee shall exercise such of
the rights and powers vested in it by this Indenture and use the same degree of
care and skill in its exercise as a prudent Person would exercise or use under
the circumstances in the conduct of his own affairs. Subject to such provisions,
the Trustee shall be under no obligation to exercise any of its rights or powers
under this Indenture at the request of any Holder of Securities, unless such
Holder shall have offered to the Trustee security and indemnity satisfactory to
it.

            (b) Except during the continuance of an Event of Default actually
known to a Responsible Officer:

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

            (2) In the absence of bad faith on its part, the Trustee may
      conclusively rely, as to the truth of the statements and the correctness
      of the opinions expressed therein, upon certificates or opinions and such
      other documents furnished to the Trustee and conforming to the
      requirements of this Indenture. However, the Trustee
   82

                                     -75-

       shall examine the certificates and opinions to determine whether or not
       they conform to the requirements of this Indenture or the Security
       Documents.

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

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

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

            (3) The Trustee shall not be liable with respect to any action it
      takes or omits to take in good faith in accordance with a direction
      received by it pursuant to Section 6.02 or 6.05.

            (d) No provision of this Indenture shall require the Trustee to
expend or risk its own funds or otherwise incur any financial liability in the
performance of any of its duties hereunder or to take or omit to take any action
under this Indenture or take any action at the request or direction of Holders
of Securities if it shall have grounds for believing that repayment of such
funds is not assured to it or it does not receive an indemnity satisfactory to
it in its sole discretion against such risk, liability, loss, fee or expense
which might be incurred by it in compliance with such request or direction.

            (e) Every provision of this Indenture that in any way relates to the
Trustee is subject to this Section 7.01.

            (f) The Trustee shall not be liable for interest on any money
received by it except as the Trustee may agree in writing with the Company.
Money held in trust by the Trustee need not be segregated from other funds
except to the extent required by law.
   83

                                     -76-


SECTION 7.02. Rights of Trustee.

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

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

            (c) The Trustee may act through its attorneys, agents, custodians
and nominees and shall not be responsible for the misconduct or negligence of
any attorney, agent, custodian or nominee (other than such a Person who is an
employee of the Trustee) appointed with due care.

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

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

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

            (g) The Trustee shall not be deemed to have notice or knowledge of
any matter, including any Default or Event of Default, unless a Responsible
Officer has actual knowledge thereof or unless written notice thereof is
received by the Trustee at its Corporate Trust Department and such notice
   84

                                     -77-


references the Securities generally, the Company or this Indenture.

SECTION 7.03. Individual Rights of Trustee.

            The Trustee in its individual or any other capacity may become the
owner or pledgee of Securities and may make loans to, accept deposits from or
perform services for and may otherwise deal with either of the Company, any of
their Subsidiaries or any of their respective Affiliates with the same rights it
would have if it were not Trustee. However, the Trustee is subject to the
provisions of Sections 7.10 and 7.11.

SECTION 7.04. Trustee's Disclaimer.

            The Trustee shall not be responsible for and makes no representation
as to the validity or adequacy of this Indenture, it shall not be accountable
for the Company's use of the proceeds from the Securities, and it shall not be
responsible for any statement of the Company or the Subsidiary Guarantors in
this Indenture, the Securities, the Security Documents or any document issued in
connection with the sale of Securities or any statement in the Securities other
than the Trustee's certificate of authentication. The Trustee makes no
representations with respect to and shall not be responsible for the
effectiveness or adequacy of this Indenture. The Trustee shall not be
responsible for independently ascertaining or maintaining such validity, if any,
and shall be fully protected in relying upon certificates and opinions delivered
to it in accordance with the terms of this Indenture.

SECTION 7.05. Notice of Default.

            If a Default or an Event of Default occurs and is continuing and a
Responsible Officer receives actual notice of such event, the Trustee shall mail
to each Holder of Securities, as their names and addresses appear on the list of
Holders of Securities described in Section 2.05, notice of the uncured Default
or Event of Default within 30 days after the Trustee receives such notice.
Except in the case of a Default or an Event of Default in payment of principal
amount, premium, if any, or interest on, any Security, including the failure to
make payment on (i) any Change of Control Purchase Date pursuant to a Change of
Control Offer or (ii) any Purchase Date pursuant to an Offer to Purchase, the
Trustee may withhold the notice if and so long as the board of directors, the
executive committee, or a trust committee of directors, of the Trustee in
   85

                                     -78-


good faith determines that withholding the notice is in the interest of the
Holders of Securities.

SECTION 7.06. Reports by Trustee to Holders.

            This Section 7.06 shall not be operative as a part of this Indenture
until this Indenture is qualified under the TIA, and, until such qualification,
this Indenture shall be construed as if this Section 7.06 were not contained
herein.

            Within 60 days after each May 15 of each year beginning with 1998,
the Trustee shall, to the extent that any of the events described in TIA 
ss.313(a) occurred within the previous twelve months, but not otherwise, mail to
each Holder of Securities a brief report dated as of such date that complies
with TIA ss. 313(a). The Trustee also shall comply with TIA ss.ss. 313(b),
313(c) and 313(d).

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

            The Company shall notify a Responsible Officer of the Trustee if the
Securities become listed on any securities exchange or of any delisting thereof.

SECTION 7.07. Compensation and Indemnity.

            The Company shall pay to the Trustee from time to time compensation
for its acceptance of this Indenture and its services hereunder. The Trustee's
compensation shall not be limited by any law on compensation of a trustee of an
express trust. The Company shall reimburse the Trustee upon request for all
disbursements, expenses and advances (including fees and expenses of counsel)
incurred or made by it in addition to the compensation for its services, except
any such disbursements, expenses and advances as may be attributable to the
Trustee's gross negligence, bad faith or willful misconduct. Such expenses shall
include the reasonable compensation, legal fees, disbursements and expenses of
the Trustee's agents, accountants, experts, nominees, custodians and counsel and
any taxes or other expenses incurred by a trust created pursuant to Section 8.01
hereof.

            The Company shall indemnify the Trustee, its directors, officers and
employees and each predecessor trustee for,
   86

                                     -79-


and hold it harmless against, any loss, liability or expense incurred by the
Trustee without gross negligence, bad faith or willful misconduct on its or
their part arising out of or in connection with the administration of this trust
and the Trustee's duties under this Indenture, including the reasonable expenses
and attorneys' fees of defending themselves against any claim of liability
arising hereunder. The Trustee shall notify the Company promptly of any claim
asserted against the Trustee for which it may seek indemnity. However, the
failure by the Trustee to so notify the Company shall not relieve the Company of
its obligations hereunder. The Company shall defend the claim and the Trustee
shall cooperate in the defense (and may employ its own counsel) at the Company's
expense. The Company need not pay for any settlement made without their written
consent, which consent shall not be unreasonably withheld or delayed. The
Company need not reimburse any expense or indemnify against any loss or
liability incurred by the Trustee as a result of the violation of this Indenture
by the Trustee if such violation arose from the gross negligence, bad faith or
willful misconduct of the Trustee.

            To secure the Company's payment obligations in this Section 7.07,
the Trustee shall have a senior Lien prior to the Securities against all money
or property held or collected by the Trustee, in its capacity as Trustee, other
than money held in trust to pay principal of and interest on particular
Securities.

            When the Trustee incurs expenses or renders services after an Event
of Default specified in clause (xi), (xii) or (xiii) of Section 6.01 occurs, the
expenses (including the reasonable fees and expenses of its agents and counsel)
and the compensation for the services shall be preferred over the status of the
Holders in a proceeding under any Bankruptcy Law and are intended to constitute
expenses of administration under any Bankruptcy Law. The Company's obligations
under this Section 7.07 and any claim arising hereunder shall survive the
resignation or removal of any Trustee, the discharge of the Company's
obligations pursuant to Article Eight, any rejection or termination under any
Bankruptcy Law and the termination of this Indenture.

SECTION 7.08.  Replacement of Trustee.

            The Trustee may resign at any time (subject to the further
provisions of this Section 7.08) by so notifying the Company in writing. The
Holders of a majority in principal
   87

                                     -80-


amount of the outstanding Securities may remove the Trustee by so notifying the
Company and the Trustee in writing and may appoint a successor trustee with the
Company's consent. The Company may remove the Trustee if:

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

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

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

            (4) the Trustee becomes legally incapable of acting with respect to
      its duties hereunder.

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

            A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Immediately after that,
the retiring Trustee shall transfer, after payment of all sums then owing to the
Trustee pursuant to Section 7.07, all property held by it as Trustee to the
successor Trustee, subject to the Lien provided in Section 7.07, the resignation
or removal of the retiring Trustee shall become effective, and the successor
Trustee shall have all the rights, powers and duties of the Trustee under this
Indenture; provided, however, that no Trustee under this Indenture shall be
liable for any act or omission of any successor Trustee. A successor Trustee
shall mail notice of its succession to each Holder of Securities.

            If a successor Trustee does not take office within 30 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Company or the
Holders of at least 10% in principal amount of the outstanding Securities may
petition any court of competent jurisdiction for the appointment of a successor
Trustee.

            If the Trustee fails to comply with Section 7.10, any Securityholder
may petition any court of competent jurisdiction
   88

                                     -81-


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

            Notwithstanding replacement of the Trustee pursuant to this Section
7.08, the Company's obligations under Section 7.07 shall continue for the
benefit of the retiring Trustee and the Company shall pay to any such replaced
or removed Trustee all amounts owed under Section 7.07 upon such replacement or
removal.

SECTION 7.09. Successor Trustee by Merger, Etc.

            If the Trustee consolidates with, merges or converts into, or
transfers all or substantially all of its corporate trust business to, another
corporation, the resulting, surviving or transferee corporation without any
further act shall, if such resulting, surviving or transferee corporation is
otherwise eligible hereunder, be the successor Trustee. 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.

SECTION 7.10. Eligibility; Disqualification.

            This Indenture shall always have a Trustee who satisfies the
requirement of TIA ss.ss. 310(a)(l) and 310(a)(5). The Trustee shall have a
combined capital and surplus of at least $50,000,000 as set forth in its most
recent published annual report of condition. The Trustee shall comply with TIA
ss. 310(b); provided, however, that there shall be excluded from the operation
of TIA ss. 310(b)(1) any indenture or indentures under which other securities,
or certificates of interest or participation in other securities, of the Company
are outstanding, if the requirements for such exclusion set forth in TIA ss.
310(b)(l) are met.

SECTION 7.11. Preferential Collection of Claims Against Company.

            The Trustee, in its capacity as Trustee hereunder, shall comply with
TIA ss. 311(a), excluding any creditor relationship listed in TIA ss. 311(b). A
Trustee who has resigned or been removed shall be subject to TIA ss. 311(a) to
the extent indicated.

                                  ARTICLE EIGHT

                             DISCHARGE OF INDENTURE


SECTION 8.01. Termination of Company's Obligations.

            This Indenture shall cease to be of further effect (except that the
Company's obligations under Section 7.07 and the Trustee's and Paying Agent's
obligations under Section 8.03 shall survive) when all outstanding Securities
theretofore authenticated and issued have been delivered (other than destroyed,
lost or stolen Securities that have been replaced or paid) to the Trustee for
cancellation and the Company have paid all sums payable hereunder.

            The Company, at its option, (i) will be discharged from any and all
obligations with respect to the Securities (except for certain obligations of
the Company to register the transfer or exchange of such Securities, replace
stolen, lost or mutilated Securities, maintain paying agencies and holding
moneys for payment in trust) or (ii) need not comply with certain of the
restricted covenants with respect to this Indenture, if the Company deposits
with the Trustee, in trust, U.S. Legal Tender or U.S. Government Obligations or
a combination thereof that, through the payment of interest and premium thereon
and principal amount at maturity in respect thereof in accordance with their
terms, will be sufficient to pay all the principal amount at maturity of and
interest and premium on the Securities on the dates such payments are due in
accordance with the terms of such Securities as well as the Trustee's fees and
expenses if the Company delivers to the Trustee:

            (A) an Opinion of Counsel and in connection with a discharge
pursuant to clause (i) above, a private letter ruling issued to the Company by
the Internal Revenue Service (the "service"), to the effect that the holders of
the Securities will not recognize income, gain or loss for federal income tax
purposes as a result of the deposit and related defeasance and will be subject
to federal income tax on the same amount and in the same manner and at the same
times as would have been the case if such option had not been exercised;

            (B) subject to certain customary qualifications, an Opinion of
Counsel to the effect that funds so deposited will not be subject to avoidance
under applicable Bankruptcy Law; and
   90

                                     -83-


            (C) an Officers' Certificate and an Opinion of Counsel to the effect
that the Company has complied with all conditions precedent to the defeasance.

            Notwithstanding the foregoing, the Opinion of Counsel required by
clause (A) above need not be delivered if all Securities not theretofore
delivered to the Trustee for cancellation (i) have become due and payable, (ii)
will become due and payable on the maturity date within one year or (iii) are to
be called for redemption within one year under arrangement satisfactory to the
Trustee for the giving of notice of redemption by the Trustee in the name, and
at the expense, of the Company. Immediately after such event, or after the
expiration of the period of time referred to in the opinion of counsel referred
to in clause (v) above; this Indenture shall cease to be of further effect, and
the Trustee, on demand of the Company, shall execute proper instruments
acknowledging confirmation of and discharge under this Indenture.

            However, the Company's obligations in Sections 2.03, 2.04, 2.05,
2.06, 2.07, 2.10, 2.12, 2.13, 4.01, 4.02 and 6.07 and Article Seven and the
Company's, the Trustee's and Paying Agent's obligations in Section 8.03 shall
survive until the Securities are no longer outstanding. Thereafter, only the
Company's obligations in Section 7.07 and the Trustee's and Paying Agent's
obligations in Section 8.03 and 8.04 shall survive. Nothing contained in this
Article Eight shall abrogate any of the rights, obligations or duties of the
Trustee under this Indenture and the Security Documents.

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

            In order to have money available on a payment date to pay principal
amount of, premium, if any, or interest on the Securities, the U.S. Government
Obligations shall be payable as to principal or interest on or before such
payment date in such amounts as will provide the necessary money. U.S.
Government Obligations shall not be callable at the issuer's option.

SECTION 8.02. Application of Trust Money.

            The Trustee or a trustee satisfactory to the Trustee and the
Company shall hold in trust money or U.S. Government
   91

                                     -84-


Obligations deposited with it pursuant to Section 8.01. It shall apply the
deposited money and the money from U.S. Government Obligations through the
Paying Agent and in accordance with this Indenture to the payment of principal
amount of, premium, if any, and interest on the Securities.

SECTION 8.03. Repayment to the Company.

            The Trustee and the Paying Agent shall promptly pay to the Company
upon delivery of an Officer's Certificate stating that such payment does not
violate the terms of this Indenture any excess money or securities held by them
or if deposited with the Trustee by any Subsidiary Guarantor, to such Subsidiary
Guarantor at any time.

            The Trustee and the Paying Agent shall pay to the Company or any
Subsidiary Guarantor, as the case may be, upon delivery of an Officer's
Certificate stating that such payment does not violate the terms of this
Indenture any money held by them for the payment of principal, premium, if any,
or interest that remains unclaimed for two years after the date upon which such
payment shall have become due; provided, however, that the Company shall have
either caused notice of such payment to be mailed to each Holder entitled
thereto no less than 30 days prior to such repayment or within such period shall
have published such notice in a financial newspaper of widespread circulation
published in the City of New York. After payment to the Company, Holders
entitled to the money must look to the Company for payment as general creditors
unless an applicable abandoned property law designates another Person, and all
liability of the Trustee and such Paying Agent with respect to such money shall
cease.

SECTION 8.04. Indemnity for Government Obligations.

            The Company shall pay and shall indemnify the Trustee against any
tax, fee or other charge imposed on or assessed against deposited U.S.
Government Obligations or the principal and interest received on such U.S.
Government Obligations.

SECTION 8.05. Reinstatement.

            If the Trustee or Paying Agent is unable to apply any money or U.S.
Government Obligations in accordance with this Indenture 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

   92

                                     -85-


application, then and only then the Company's and each Subsidiary Guarantor's,
if any, obligations under this Indenture and the Securities shall be revived and
reinstated as though no deposit had been made pursuant to this Indenture until
such time as the Trustee is permitted to apply all such money or U.S. Government
Obligations in accordance with this Indenture; provided, however, that if the
Company or the Subsidiary Guarantors, as the case may be, have made any payment
of principal amount of, premium, if any, or interest on any Securities because
of the reinstatement of their obligations, the Company or the Subsidiary
Guarantors, as the case may be, shall be subrogated to the rights of the Holders
of such Securities to receive such payment from the money or U.S. Government
Obligations held by the Trustee or Paying Agent.

                                  ARTICLE NINE

                       AMENDMENTS, SUPPLEMENTS AND WAIVERS

SECTION 9.01.  Without Consent of Holders.

            The Company and the Subsidiary Guarantors (when authorized by Board
Resolutions), and the Trustee, together, may amend or supplement this Indenture,
the Securities and the Guarantees, without notice to or consent of any
Securityholder:

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

            (2) to evidence the succession in accordance with Article Five
      hereof of another Person to a Company or a Subsidiary Guarantor and the
      assumption by any such successor of the covenants of a Company or a
      Subsidiary Guarantor herein and in the Securities or a Guarantee, as the
      case may be;

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

            (4) to make any other change that does not adversely affect the
      rights of any Holders of Securities hereunder or thereunder;
   93

                                     -86-


            (5) to mortgage, pledge or grant a security interest in favor of the
      Trustee as additional security for the payment and performance of
      obligations under this Indenture, the Securities and the Guarantees;

            (6) to comply with any requirements of the Commission in connection
      with the qualification of this Indenture under the TIA;

            (7) to add or release any Subsidiary Guarantor strictly in

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

SECTION 9.02. With Consent of Holders.

            Subject to Section 6.07, the Company and the Subsidiary Guarantors
(when authorized by Board Resolutions) and the Trustee, together, with the
written consent (which may include consents obtained in connection with a tender
offer or exchange offer for Securities) of the Holder or Holders of at least a
majority in aggregate principal amount of the outstanding Securities, may amend
or supplement this Indenture, the Securities or the Guarantees without notice to
any other Holders of Securities. Subject to Section 6.07, the Holder or Holders
of a majority in aggregate principal amount of the outstanding Securities may by

offer for Securities) waive any existing Default (other than any continuing
Default or Event of Default in the payment of the principal amount of, premium,
if any, or interest on Securities) under, or compliance by the Company with any
provision of, this Indenture or the Securities without notice to any other

      Securities in any manner adverse to any Holder;

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

            (6) make any changes in Section 6.04, 6.07 or this Section 9.02;

            (7) make the principal of, or the interest on any Security payable
      in money other than as provided for in this Indenture, the Securities and
      the Guarantees as in effect on the date hereof;

            (8) make any changes in the provisions described in Section 4.20 or
      in the obligations of the Company to make a Net Proceeds Offer or Special
      Offer or the definitions related thereto that could adversely affect the
      rights of any Holder of the Securities; or

            (9) take any action that would subordinate the Securities or the
      Subsidiary Guarantees to any other Indebtedness of the Company or any of
      its Subsidiaries, respectively, or otherwise affect the ranking of the
      Securities or the Subsidiary Guarantees.

            It shall not be necessary for the consent of the Holders under this
Section 9.02 to approve the particular form of any proposed amendment,
supplement or waiver, but it shall be sufficient if such consent approves the
substance thereof.
   95

                                      -88-


            After an amendment, supplement or waiver under this Section 9.02
becomes effective, the Company shall mail to the Holders of Securities affected
thereby a notice briefly describing the amendment, supplement or waiver. Any
failure of the Company to mail such notice, or any defect therein, shall not,
however, in any way impair or affect the validity of any such supplemental
indenture.

SECTION 9.03. Compliance with TIA.

            From the date on which this Indenture is qualified under the TIA,
every amendment, waiver or supplement of this Indenture, the Security Documents,
the Securities or the Guarantees shall comply with the TIA as then in effect and
to the extent applicable thereto.

SECTION 9.04. Revocation and Effect of Consents.

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

            The Company may, but shall not be obligated to, fix a record date
for the purpose of determining the Holders of Securities entitled to consent to
any amendment, supplement or waiver, which record date shall be at least 30 days
prior to the first solicitation of such consent. If a record date is fixed, then
notwithstanding the last sentence of the immediately preceding paragraph, those
Persons who were Holders of Securities at such record date (or their duly
designated proxies), and only those Persons, shall be entitled to revoke any
consent previously given, whether or not such Persons continue to be Holders
after such record date. No such consent shall be valid or effective for more
than 90 days after such record date.
   96

                                     -89-


            After an amendment, supplement or waiver becomes effective, it shall
bind every Holder, unless it makes a change described in any of clauses (1)
through (9) of Section 9.02, in which case, the amendment, supplement or waiver
shall bind only each Holder of a Security who has consented to it and every
subsequent Holder of a Security or portion of a Security that evidences the same
debt as the consenting Holder's Security; provided that any such waiver shall
not impair or affect the right of any Holder to receive payment of principal of
and interest on a Security, on or after the respective due dates expressed in
such Security, or to bring suit for the enforcement of any such payment on or
after such respective dates without the consent of such Holder.

SECTION 9.05. Notation on or Exchange of Securities.

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

SECTION 9.06. Trustee to Sign Amendments, Etc.

            The Trustee shall execute any amendment, supplement or waiver to any
agreement authorized pursuant to this Article Nine; provided that (i) the form
of any amendment, supplement or waiver with respect to the matters referred to
in clauses (1) through (9) of Section 9.02 shall be satisfactory to the Trustee
and (ii) the Trustee may, but shall not be obligated to, execute any such
amendment, supplement or waiver which affects its own rights, duties or
immunities under this Indenture or the Security Documents. The Trustee shall be
entitled to receive, and shall be fully protected in relying upon, an Opinion of
Counsel and an Officers' Certificate of the Company each stating, in addition to
the matters set forth in Section 11.04, that the execution of any amendment,
supplement or waiver authorized pursuant to this Article Nine is authorized or
permitted by this Indenture and constitutes the legal, valid and binding
obligations of the Company, the Subsidiary Guarantors or the Pledgors, as the
case may be, enforceable in accordance with its terms. Such Opinion of Counsel
shall be at the expense of the Company, and the Trustee shall have a Lien under
Section 7.07 for any such expense.

                                   ARTICLE TEN

                                   GUARANTEES

SECTION 10.01.  Unconditional Guarantee.

            Each Subsidiary Guarantor, jointly and severally, hereby
unconditionally guarantees (such guarantee to be referred to herein as a
"Guarantee") to each Holder of a Security authenticated and delivered by the
Trustee and to the Trustee and its successors and assigns that: (i) the
principal amount of, premium, if any, and interest on the Securities will be
promptly paid in full when due, subject to any applicable grace period, whether
at maturity, by acceleration or otherwise and interest on the overdue principal
and interest on any overdue interest, to the extent lawful, of the Securities
and all other Obligations of the Company to the Holders of the Securities or the
Trustee hereunder or thereunder will be promptly paid in full or performed, all
in accordance with the terms hereof and thereof; and (ii) in case of any
extension of time of payment or renewal of any Securities or of any such other
Obligations, the same will be promptly paid in full when due or performed in
accordance with the terms of the extension or renewal, subject to any applicable
grace period, whether at stated maturity, by acceleration or otherwise, subject,
however, in the case of clauses (i) and (ii) above, to the limitations set forth
in Section 10.03. Each Subsidiary Guarantor hereby agrees that its obligations
hereunder shall be unconditional, irrespective of the validity, regularity or
enforceability of the Securities or this Indenture, the absence of any action to
enforce the same, any waiver or consent by any Holder of the Securities with
respect to any provisions hereof or thereof, the recovery of any judgment
against the Company, and action to enforce the same or any other circumstance
which might otherwise constitute a legal or equitable discharge or defense of a
guarantor. Each Subsidiary Guarantor hereby waives diligence, presentment,
demand of payment, filing of claims with a court in the event of insolvency or
bankruptcy of the Company, any right to require a proceeding first against the
Company, protest, notice and all demands whatsoever and covenants that this
Guarantee will not be discharged except by complete performance of the
obligations contained in the Securities, this Indenture and in this Guarantee.
If any Holder of the Securities or the Trustee is required by any court or
otherwise to return to the Company or any Subsidiary Guarantor, or any
custodian, trustee, liquidator or other similar official
   98

                                     -91-


acting in relation to the Company or any Subsidiary Guarantor, any amount paid
by the Company or any Subsidiary Guarantor to the Trustee or such Holder, this
Guarantee, to the extent theretofore discharged, shall be reinstated in full
force and effect. Each Subsidiary Guarantor further agrees that, as between each
Subsidiary Guarantor, on the one hand, and the Holders of the Securities and the
Trustee, on the other hand, (x) the maturity of the obligations guaranteed
hereby may be accelerated as provided in Article Six for the purposes of this
Guarantee, notwithstanding any stay, injunction or other prohibition preventing
such acceleration against the Company in respect of the obligations guaranteed
hereby, and (y) in the event of any acceleration of such obligations as provided
in Article Six, such obligations (whether or not due and payable) shall
forthwith become due and payable by each Subsidiary Guarantor for the purpose of
this Guarantee.

SECTION 10.02. Severability.

            In case any provision of this Article Ten or any Guarantee shall be
invalid, illegal or unenforceable, the validity, legality, and enforceability of
the remaining provisions hereof or thereof shall not in any way be affected or
impaired thereby.

SECTION 10.03. Limitation of Subsidiary Guarantors' Liability.

            It is the intention of all parties hereto that the guarantee by each
Subsidiary Guarantor pursuant to its Guarantee not constitute a fraudulent
transfer or conveyance for purposes of any Bankruptcy Law, the Uniform
Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar
Federal, state or foreign law. To effectuate the foregoing intention, the
Holders of Securities and each Subsidiary Guarantor incorporated in one of the
States of the United States hereby irrevocably agree that the obligations of
such Subsidiary Guarantor under its Guarantee shall be limited to the maximum
amount as will, after giving effect to all other contingent and fixed
liabilities of such Subsidiary Guarantor and after giving effect to any
collections from or payments made by or on behalf of any other Subsidiary
Guarantor in respect of the obligations of such other Subsidiary Guarantor under
its Guarantee or pursuant to Section 10.04, result in the obligations of such
Subsidiary Guarantor under its Guarantee not constituting such fraudulent
transfer or conveyance.
   99

                                     -92-


SECTION 10.04. Contribution.

            In order to provide for just and equitable contribution among the
Subsidiary Guarantors, the Subsidiary Guarantors agree, inter se that in the
event any payment or distribution is made by any Subsidiary Guarantor (a
"Funding Subsidiary Guarantor") under its Guarantee, such Funding Subsidiary
Guarantor shall be entitled to a contribution from all other Subsidiary
Guarantors in a pro rata amount based on the Adjusted Net Assets (as defined
below) of each Subsidiary Guarantor (including the Funding Subsidiary Guarantor)
for all payments, damages and expenses incurred by that Funding Subsidiary
Guarantor in discharging the Company's obligations with respect to the
Securities or any other Subsidiary Guarantor's obligations with respect to its
Guarantee. "Adjusted Net Assets" of such Subsidiary Guarantor at any date shall
mean the lesser of (x) the amount by which the fair value of the property of
such Subsidiary Guarantor exceeds the total amount of liabilities, including,
without limitation, contingent liabilities (after giving effect to all other
fixed and contingent liabilities incurred or assumed on such date (other than
liabilities of such Subsidiary Guarantor under Indebtedness subordinated to such
Subsidiary Guarantor's Guarantee)), but excluding liabilities under the
Guarantee, of such Subsidiary Guarantor at such date and (y) the amount by which
the present fair salable value of the assets of such Subsidiary Guarantor at
such date exceeds the amount that will be required to pay the probable liability
of such Subsidiary Guarantor on its debts (after giving effect to all other
fixed and contingent liabilities incurred or assumed on such date and after
giving effect to any collection from any Subsidiary of such Subsidiary Guarantor
in respect of the obligations of such Subsidiary under its Guarantee, if any),
excluding debt in respect of the Guarantee of such Subsidiary Guarantor, as they
become absolute and matured.

SECTION 10.05. Waiver of Subrogation.

            Until all Guarantee Obligations are paid in full, each Subsidiary
Guarantor hereby irrevocably waives any claims or other rights which it may now
or hereafter acquire against the Company that arise from the existence, payment,
performance or enforcement of such Subsidiary Guarantor's obligations under its
Guarantee and this Indenture, including, without limitation, any right of
subrogation, reimbursement, exoneration, indemnification, and any right to
participate in any claim or remedy of any Holder of Securities against the
Company, whether or not such claim, remedy or right arises in equity, or under
   100

                                     -93-


contract, statute or common law, including, without limitation, the right to
take or receive from the Company, 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 any Subsidiary
Guarantor in violation of the preceding sentence and the Securities shall not
have been paid in full, such amount shall have been deemed to have been paid to
such Subsidiary Guarantor for the benefit of, and held in trust for the benefit
of, the Holders of the Securities, and shall forthwith be paid to the Trustee
for the benefit of such Holders to be credited and applied upon the Securities,
whether matured or unmatured, in accordance with the terms of this Indenture.
Each Subsidiary Guarantor acknowledges that it will receive direct and indirect
benefits from the financing arrangements contemplated by this Indenture and that
the waiver set forth in this Section 10.05 is knowingly made in contemplation of
such benefits.

SECTION 10.06. Execution of Guarantee.

            To evidence its guarantee to the Holders of Securities set forth in
this Article Ten, each Subsidiary Guarantor hereby agrees to execute its
Guarantee in substantially the form included in the Securities, which shall be
endorsed on each Security ordered to be authenticated and delivered by the
Trustee. Each Subsidiary Guarantor hereby agrees that its Guarantee set forth in
this Article Ten shall remain in full force and effect notwithstanding any
failure to endorse on each Security a notation of such Guarantee. Each such
Guarantee shall be signed on behalf of each Subsidiary Guarantor by two
Officers. Such signatures upon the Guarantee may be by manual or facsimile
signature of such officers and may be imprinted or otherwise reproduced on the
Guarantee, and in case any such officer who shall have signed the Guarantee
shall cease to be such officer before the Security on which such Guarantee is
endorsed shall have been authenticated and delivered by the Trustee or disposed
of by the Company, such Security nevertheless may be authenticated and delivered
or disposed of as though the Person who signed the Guarantee had not ceased to
be such officer of the Subsidiary Guarantor.

SECTION 10.07. Waiver of Stay, Extension or Usury Laws.

            Each Subsidiary Guarantor covenants (to the extent that it may
lawfully do so) that it will not at any time insist upon, plead, or in any
manner whatsoever claim or take the benefit or advantage of, any stay or
extension law or any usury
   101

                                     -94-


law or other law that would prohibit or forgive each such Subsidiary Guarantor
from performing its Guarantee as contemplated herein, wherever enacted, now or
at any time hereafter in force, or which may affect the covenants or the
performance of this Indenture; and (to the extent that it may lawfully do so)
such Subsidiary Guarantor 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.

                                 ARTICLE ELEVEN

SECTION 11.08. Governing Law.

            THIS INDENTURE, THE SECURITIES AND THE GUARANTEES SHALL BE GOVERNED
BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, AS
APPLIED TO CONTRACTS MADE AND PERFORMED WITHIN THE STATE OF NEW YORK, WITHOUT
REGARD TO PRINCIPLES OF CONFLICTS OF LAW. Each of the parties hereto agrees to
submit to the nonexclusive jurisdiction of the courts of the State of New York
and the U.S. Federal Courts sitting in the City of New York for the purposes of
any suit, action or proceeding arising out of or relating to this Indenture. The
Company and the Subsidiary Guarantors hereby designate and appoint CT
Corporation System, 1633 Broadway, New York, New York 10019, as its agent to
receive on its behalf service of all process in any proceedings in any court
sitting in New York, New York, such service being hereby acknowledged by the
Company and Subsidiary Guarantors to be effective and binding service in every
respect. A copy of any such process so served shall be mailed by registered mail
to the Company and Subsidiary Guarantors, at their respective address specified
in Section 11.02 hereof, except that unless otherwise provided by applicable
law, any failure to mail such copy shall not affect the validity of service of
process. If any agent appointed by the Company and Subsidiary Guarantors refuses
to accept service, the Company and Subsidiary Guarantors hereby agree that
service upon them by mail shall constitute sufficient notice. Nothing herein
shall affect the right to serve process in any other manner permitted by law or
shall limit the right of the Trustee to bring proceedings against the Company
and Subsidiary Guarantors in the courts of any other jurisdiction.

SECTION 11.09.  No Adverse Interpretation of Other Agreements. 

            This Indenture may not be used to interpret another indenture, loan
or debt agreement of any of the Company or any
   105

                                     -98-


of its Subsidiaries.  Any such indenture, loan or debt agreement may not be
used to interpret this Indenture.

SECTION 11.10. No Recourse Against Others.

            A director, officer, employee, its direct or indirect stockholder or
incorporator, as such, of the Company or any of its Subsidiaries, shall not have
any liability for any obligations of the Company or the Subsidiary Guarantors
under the Securities, this Indenture or the Guarantees or for any claim based
on, in respect of or by reason of such obligations or their creations. Each
Holder of Securities by accepting a Security waives and releases all such
liability. Such waiver and release are part of the consideration for the
issuance of the Securities.

SECTION 11.11. Successors.

            All agreements of the Company and the Subsidiary Guarantors in this
Indenture, the Securities and the Guarantees shall bind their respective
successors. All agreements of the Trustee in this Indenture shall bind its
successors.

            All parties may sign any number of copies of this Indenture. Each
signed copy or counterpart shall be an original, but all of them together shall
represent the same agreement.

SECTION 11.13. Severability.

            In case any one or more of the provisions in this Indenture, in the
Securities or in the Guarantees shall be held invalid, illegal or unenforceable,
in any respect for any reason, the validity, legality and enforceability of any
such provision in every other respect and of the remaining provisions shall not
in any way be affected or impaired thereby, it being intended that all of the
provisions hereof shall be enforceable to the full extent permitted by law.

SECTION 11.14. Tax Considerations.

            It is the intention of the parties hereto that for U.S. Federal,
state and local income tax purposes: (i) neither the Holders nor the Trustee
shall be at any time the owner of the Collateral for U.S. Federal, state or
local tax purposes
   106

                                     -99-


and (ii) the arrangement created hereby is intended solely to be a security
arrangement and not a trust and neither the Trustee nor the Holders shall file
any returns, reports or other documents or take any position inconsistent
therewith for U.S. Federal, state or local tax law purposes.

                     10 3/4% Senior Notes due 2007, Series A

1.    Interest.

            United Refining Company, a Pennsylvania corporation (the "Company"),
promises to pay interest on the principal amount of this Security at the rate
per annum shown above. The Company will pay interest semi-annually on June 15
and December 15 of each year (the "Interest Payment Date"), commencing December
15, 1997. Interest on the Securities will accrue from the most recent date to
which interest has been paid or, if no interest has been paid, from June 9,
1997. Interest will be computed on the basis of a 360-day year of twelve 30-day
months.

            The Company shall pay interest on overdue principal from time to
time on demand at the rate borne by the Securities plus 2% and on overdue
installments of interest (without regard to any applicable grace periods) to the
extent lawful.

2.    Method of Payment.

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

3.    Paying Agent and Registrar.

            IBJ Schroder Bank & Trust Company (the "Trustee") will act as Paying
Agent and Registrar. The Company may change any Registrar or co-Registrar
without notice to the Holders;
   117
                                       -2-


however, the Paying Agent shall always be the Trustee or any successor trustee,
under the Indenture.

4.    Indenture and Guarantees.

            The Company issued the Securities under an Indenture, dated as of
June 9, 1997 (the "Indenture"), among the Company, the Subsidiary Guarantors and
the Trustee. Capitalized terms herein are used as defined in the Indenture
unless otherwise defined herein. 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 of 1939 (15 U.S.C. ss.ss. 77aaa-77bbbb) (the "TIA"), as in
effect on the date of the Indenture until such time as the Indenture is
qualified under the TIA, and thereafter as in effect on the date on which the
Indenture is qualified under the TIA, except as provided in the Indenture.
Notwithstanding anything to the contrary herein, the Securities are subject to
all such terms, and Holders of Securities are referred to the Indenture and the
TIA for a statement of them. The Securities are unsecured obligations of the
Company limited in aggregate principal amount to $200,000,000. Payment on each
Security is guaranteed on a senior basis, jointly and severally, by the
Subsidiary Guarantors pursuant to Article Ten of the Indenture.

5.    Redemption.

            (a) Optional Redemption. The Securities will be redeemable, at the
Company's option, in whole at any time or in part from time to time, on and
after June 15, 2002 at the following redemption prices (expressed as percentages
of the principal amount), together with accrued and unpaid interest, if any,
thereon to the Redemption Date if redeemed during the 12-month period 
beginning               :

             Year                                Percentage
             ----                                ----------
             2002 .............................    105.375%
             2003 .............................    103.583%
             2004 .............................    101.792%
             2005  and thereafter .............    100.000%

            (b) Optional Redemption upon Public Equity Offering. On or prior to
June 15, 2000, the Company may redeem up to 35% of the aggregate principal
amount of the Securities with the net cash proceeds of one or more Equity
Offerings at a redemption price equal to 110.0% of the principal amount thereof,

   118
                                       -3-


plus accrued and unpaid interest, if any, to the Redemption Date; provided that
(a) at least $100 million aggregate principal amount of the Securities remain
outstanding immediately after the occurrence of such redemption and (b) such
redemption occurs within 60 days of the date of the closing of any such Equity
Offering.

            (c)  Selection of Securities for Redemption.  If less than all of
the Securities are to be redeemed at any time, selection of the Securities to
be redeemed will be made by the Trustee from among the outstanding Securities
on a pro rata basis, by lot or by any other method permitted in the 
Indenture.

6.    Notice of Redemption.

            Notice of redemption will be mailed at least 30 days but not more
than 60 days before the Redemption Date to each Holder of Securities to be
redeemed at such Holder's registered address. Securities in denominations of
$1,000 may be redeemed only in whole. The Trustee may select for redemption
portions (equal to $1,000 or any integral multiple thereof) of the principal of
Securities that have denominations larger than $1,000.

            If any Security is to be redeemed in part only, the notice of
redemption that relates to such Security shall state the portion of the
principal amount thereof to be redeemed. A new Security in a principal amount
equal to the unredeemed portion thereof will be issued in the name of the Holder
thereof upon cancellation of the original Security. On and after the Redemption
Date, interest will cease to accrue on Securities or portions thereof called for
redemption.

7.    Denominations; Transfer; Exchange.

            The Securities are in registered form, without coupons, in
denominations of U.S.$1,000 and integral multiples of U.S.$1,000. A Holder shall
register the transfer of or exchange 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 certain transfer
taxes or similar governmental charges payable in connection therewith as
permitted by the Indenture. The Registrar need not register the transfer of or
exchange any Securities or portions thereof selected for redemption, except the
unredeemed portion of any Security being redeemed in part.
   119

                                       -4-


8.    Persons Deemed Owners.

            The registered Holder of a Security shall be treated as the owner of
it for all purposes.

9.    Unclaimed Funds.

            If funds for the payment of principal or interest remain unclaimed
for two years, the Trustee and the Paying Agent will repay the funds to the
Company at their request. After that, all liability of the Trustee and Paying
Agent with respect to such funds shall cease.

10.   Discharge.

            The Company may be discharged from their obligations under the
Indenture and the Securities except for certain provisions thereof, upon
satisfaction of certain conditions specified in the Indenture.

11.   Amendment; Supplement; Waiver.

            Subject to certain exceptions, the Indenture or the Securities may
be amended or supplemented with the written consent (which may include consents
obtained in connection with a tender offer or exchange offer for securities) of
the Holders of at least a majority in aggregate principal amount of the
Securities then outstanding, and any existing Default or Event of Default or
compliance with any provision may be waived other than any continuing Default or
Event of Default in the payment of the principal amount of, premium, if any, or
interest on the Securities with the consent (which may include consents obtained
in connection with a tender offer or exchange offer for securities) of the
Holders of a majority in aggregate principal amount of the Securities then
outstanding. Without 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, provide for uncertificated Securities in
addition to or in place of certificated Securities to provide for the assumption
of the Company's obligations to Holders in the case of a merger or acquisition
or comply with any requirements of the Commission in connection with the
qualification of the Indenture under the TIA, or make any other change that does
not materially adversely affect the rights of any Holder of a Security.
   120

                                       -5-


14.   Restrictive Covenants.

            The Indenture contains certain covenants that, among other things,
limit the ability of the Company and their subsidiaries to make Restricted
Payments, to incur Indebtedness, to create Liens, to issue preferred or other
Capital Stock of Subsidiaries, to sell assets, to permit restrictions on
dividends and other payments by subsidiaries to the Company, to consolidate,
merge or sell all or substantially all of their assets, to engage in
transactions with Affiliates or to engage in certain businesses. The limitations
are subject to a number of important qualifications and exceptions. The Company
must report to the Trustee on compliance with such limitations.

15.   Defaults and Remedies.

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

16.   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 otherwise deal
with the Company, their Subsidiaries or their respective Affiliates as if it
were not the Trustee.

17.   No Recourse Against Others.

            No director, officer, employee, direct or indirect stockholder or
incorporator, as such, of the Company or any of their Subsidiaries, including
but not limited to Parent and its
   121

                                       -6-


stockholders, shall have any liability for any obligation of the Company under

1.     Interest.

            United Refining Company, a Pennsylvania corporation (the "Company"),
hereby jointly and severally promises to pay interest on the principal amount of
this Security at the rate per annum shown above. The Company will pay interest
semi-annually on June 15 and December 15 of each year (the "Interest Payment
Date"), commencing December 15, 1997. Interest on the Securities will accrue
from the most recent date to which interest has been paid or, if no interest has
been paid, from June 9, 1997. Interest will be computed on the basis of a
360-day year of twelve 30-day months.

            The Company shall pay interest on overdue principal from time to
time on demand at the rate borne by the Securities plus 2% and on overdue
installments of interest (without regard to any applicable grace periods) to the
extent lawful.

2.     Method of Payment.

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

3.     Paying Agent and Registrar.

            IBJ Schroder Bank & Trust Company (the "Trustee") will act as Paying

Trustee or any successor trustee under the Indenture.

the Trustee. Capitalized terms herein are used as defined in the Indenture
unless otherwise defined herein. The terms of the Securities include those

Notwithstanding anything to the contrary herein, the Securities are subject to
all such terms, and Holders of Securities are referred to the Indenture and the
TIA for a statement of them. The Securities are unsecured obligations of the
Company limited in aggregate principal amount to $200,000,000. Payment on each

equal to the unredeemed portion thereof will be issued in the name of the Holder
thereof upon cancellation of the original Security. On and after the Redemption

redemption.

Indenture. The Registrar may require a Holder, among other things, to furnish
appropriate endorsements and transfer documents and to pay certain transfer
taxes or similar governmental charges payable in connection therewith as
permitted by the Indenture. The Registrar need not register the transfer of or
exchange any Securities or portions thereof selected for redemption, except the
unredeemed portion of any security being redeemed in part.

respect of or by reason of, such obligations or their creation. Each Holder of a
Security by accepting a Security waives and releases all such liability. Such
waiver and release are part of the consideration for the issuance of the
Securities.

           (the "Indenture") relating to 10 3/4%
           Senior Notes due 2007, Series A

Ladies and Gentlemen:

            In connection with our proposed purchase of 10 3/4% Senior Notes due
2007, Series A (the "Securities"), of the Company, we confirm that:

            1. We have received such information as we deem necessary in order
to make our investment decision.

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

            3. We understand that the offer and sale of the Securities have not
been registered under the Securities Act, and that the Securities may not be
offered or sold within the United States or to, or for the account or benefit
of, U.S. Persons except as permitted in the following sentence. We agree, on our
own behalf and on behalf of each account for which we acquire any Securities,
that, prior to (x) the date which is two years after the later of the date of
original issuance of the Securities and (y) such later date, if any, as may be
required by applicable laws, the Securities may be offered, resold, pledged or
otherwise transferred only (a) to the Company, (b) inside the United States to a
Person whom we reasonably believe to be a "qualified institutional buyer" (as
defined in Rule 144A under the Securities Act) in compliance
   148

                                     -2-


with Rule 144A under the Securities Act, (c) inside the United States to a
Person we reasonably believe to be an institutional accredited investor" (as
defined below) that, prior to such transfer, furnishes to the Trustee a signed
letter substantially in the form hereof, (d) outside the United States to
Persons other than U.S. Persons in offshore transactions meeting the
requirements of Rule 904 under Regulation S under the Securities Act, (e)
pursuant to the exemption from registration provided by Rule 144 under the
Securities Act (if available), (f) pursuant to an effective registration
statement under the Securities Act or (g) pursuant to another available
exemption from the registration requirements of the Securities Act, and, in each
case, in accordance with any applicable securities laws of any state of the
United States or any other applicable jurisdiction, and we further agree to
provide to any Person purchasing Securities from us a notice advising such
purchaser that resales of the Securities are restricted as stated herein.

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

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

            6. We are acquiring the Securities purchased by us for our account
or for one or more accounts (each of which is an institutional "accredited
investor") as to each of which we exercise sole investment discretion.
