     Each party agrees as follows for the benefit of the other party and for the
equal and ratable benefit of the Holders of the Issuers' Senior Third Secured
Notes due 2014 (the "Notes").

                                    ARTICLE I

                   DEFINITIONS AND INCORPORATION BY REFERENCE
                   ------------------------------------------

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

     "10 1/2% Notes" means the 10 1/2% Senior Notes Due 2007 issued by the
Operating Partnership and Petro Financial Corporation pursuant to an indenture
dated January 30, 1997, as amended on July 23, 1999 between the Operating
Partnership, Petro Financial Corporation and State Street Bank and Trust
Company, as trustee.

     "Accreted Value" means, as of any date prior to April 30, 2009, an amount
per $1,000 principal amount at Stated Maturity of Notes that is equal to the sum
of (a) the Initial Accreted Amount and (b) the portion of the excess of the
principal amount at Stated Maturity of each Note over the Initial Accreted
Amount which shall have been amortized on a daily basis and compounded
semi-annually on each April 30 and October 31 at the rate of 4% per annum from
the Issue Date through the date of determination computed on the basis of a
360-day year of twelve 30-day months; and, as of any date on or after May 1,
2009, the Accreted Value of each Note shall mean the aggregate principal amount
at Stated Maturity of such Note.

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

     "Additional Interest" means additional interest on the Notes, which the
Issuers agree to pay pursuant to Section 5 of the Registration Rights Agreement.

     "Adjusted Interest Expense" means, for any period, without duplication, an
amount equal to the sum of: (i) the aggregate amount of interest charges
(excluding fees and expenses incurred at or prior to the Issue Date in
connection with the Transactions and any expenses, interest or charges related
to Petro Warrant Holdings Corporation, the Warrants or the obligation or right
of the Company to purchase the Warrants), whether expensed or capitalized,
incurred or accrued by the Company and its Restricted Subsidiaries, determined
on a consolidated basis in accordance with GAAP for such period (including
non-cash interest payments); plus (ii) to the extent not included in clause (i)
above, an amount equal to the sum of: (A) net costs associated with Interest
Swap Obligations and Currency Hedge Obligations (including any amortization of
discounts); plus (B) all commissions, discounts and other fees and charges owed
with respect to letters of credit, bankers' acceptances or similar facilities
paid or accrued, or scheduled to be

                                        3

paid or accrued, during such period; plus (C) dividends on Preferred Interests
and Redeemable Capital Interests (if paid to a Person other than the Company or
one of its Restricted Subsidiaries) declared and payable in cash; plus (D) to
the extent any Debt of any other Person is Guaranteed or secured by the Company
or a Restricted Subsidiary in the manner described in clause (viii) of the
definition of "Debt," the aggregate amount of interest expense of such other
Person during such period attributable to any such Debt determined in accordance
with GAAP; minus (iii) amortization or write-off of deferred financing costs
during such period and any charge related to any premium or penalty paid in
connection with redeeming or retiring any Debt of the Company and its Restricted
Subsidiaries prior to the Stated Maturity thereof. For purposes of calculating
Adjusted Interest Expense on a pro forma basis, the interest on Debt bearing a
floating rate of interest shall be the interest rate in effect at the time of
determination (taking into account on a pro forma basis any Interest Swap
Obligation applicable to such Debt if such Interest Swap Obligation has a
remaining term at the date of determination in excess of 12 months).
Notwithstanding the foregoing, accrued but unpaid dividends on the Preferred
Interests (including, the Class A and Class B preferred partnership interests)
in the Company shall not be deemed interest expense for purposes of the
definition of "Adjusted Interest Expense".

     "Adjusted Net Income" means, for any period, the consolidated net income
(or net loss) of the Company and its Restricted Subsidiaries determined in
accordance with GAAP for such period minus (to the extent made or reserved)
Permitted Tax Distributions, plus any Permitted Tax Distributions repaid to the
Company; provided that there shall be excluded therefrom, without duplication:
(i) all items classified as extraordinary, unusual or nonrecurring (including
fees and expenses incurred at or prior to the Issue Date and write-offs, in each
case in connection with the Transactions); (ii) any net loss or net income of
any Person that is not a Restricted Subsidiary, except to the extent of the
amount of dividends or other distributions actually paid to the Company or its
Restricted Subsidiaries by such other Person during such period; (iii) the net
income of any Person acquired by the Company or a Restricted Subsidiary thereof
in a pooling-of-interests transaction for any period prior to the date of such
acquisition; (iv) any gain or loss, net of taxes, realized on the termination of
any employee pension benefit plan; (v) gains and losses in respect of Asset
Sales by the Company or its Restricted Subsidiaries; (vi) with regard to any
Restricted Subsidiary all of the Capital Interests which are not owned by the
Company or another Restricted Subsidiary, any aggregate net income (or loss) in
excess of the Company's or such other Restricted Subsidiary's pro rata share of
such Restricted Subsidiary's net income (or loss); (vii) any expenses or charges
related to Petro Warrant Holdings Corporation, the Warrants or the obligation or
right of the Company to purchase the Warrants; (viii) any net income or loss
from the early extinguishment of Debt; and (ix) any goodwill impairment charge
pursuant to Financial Accounting Standards Board Statement No. 142 - "Goodwill
and Other Intangible Assets". In computing Adjusted Net Income under Section
4.8(a)(ii) hereof, the Company (i) shall use audited financial statements for
the portion of the relevant period for which such statements are available on
the date of determination and unaudited financial statements and other current
financial data based on the books and records of the Company for the remaining
portion of such period and (ii) shall be permitted to rely in good faith for the
balance of the relevant period for which audited financial statements are not
available on the financial statements and other financial data derived from the
books and records of the Company that are available on the date of
determination.

Agent. The Issuers shall notify the Trustee of the name and address of any such
Agent. If the Issuers fail to maintain a Registrar or Paying Agent, or agent for

Trustee shall act as such and shall be entitled to appropriate compensation
pursuant to Section 7.7. The Issuers initially appoint the Trustee as Registrar,

<PAGE>

notify the Trustee of any default by the Issuers (or any other obligor on the
Notes) in making any such payment. Money held in trust by the Paying Agent need
not be segregated except as required by law and in no event shall the Paying
Agent be liable for any interest on any money received by it hereunder. The
Issuers at any time may require a Paying Agent to pay all money held by it to
the Trustee and the Trustee may, at any time during the continuance of any Event
of Default specified in Section 6.1(1) or (2), upon written request to a Paying
Agent, require such Paying Agent to forthwith pay to the Trustee all sums so
held in trust by such Paying Agent together with a complete accounting of such

Trustee on or before each January 15 and July 15 in each year, and at such other

request to register the transfer thereof, the Registrar shall register the
transfer as requested and, when Notes are presented to the Registrar with a
request to exchange them for an equal principal amount of Notes of other
authorized denominations, the Registrar shall make the exchange as requested,
provided that every Note presented or surrendered for registration of transfer
or exchange shall be duly endorsed or be accompanied by a written instrument of
transfer in form satisfactory to the Issuers and the Registrar duly executed by
the Holder thereof or his attorney, duly authorized in writing. To permit
registration of transfers and exchanges, upon surrender of any Note for
registration of transfer at the office or agency maintained pursuant to Section
2.3 hereof, the Issuers shall issue and execute and the Trustee shall
authenticate Notes at the Registrar's request. Any exchange or transfer shall be
without any service charge to the Holder, except that the Issuers may require
payment by the Holder of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation to a transfer or exchange, but this
provision shall not apply to any exchange pursuant to Section 2.9, 3.6 or 8.5
hereof. The Trustee shall not be required to register transfers of Notes or to
exchange Notes for a period of 15 days before selection of any Notes to be
redeemed or purchased pursuant to Sections 4.9 and 4.18. The Trustee shall not
be required to exchange or register transfers of any Notes called or being
called for redemption or selected or being selected for repurchase in whole or
in part, except the unredeemed or unpurchased portion of any Note being redeemed
or repurchased in part.

agree that transfers of the beneficial interests in such Global Note may be
effected only through a book entry system maintained by the Holder of such
Global Note (or its agent), and that ownership of a beneficial interest in the
Global Note shall be required to be reflected in a book entry. Each Holder of a
Note agrees to indemnify the Issuers and the Trustee against any liability that
may

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

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

     Notes outstanding at any time are all Notes authenticated by the Trustee
except for those cancelled by it, those delivered to it for cancellation, and
those described in this Section 2.8 as not outstanding. If a Note is replaced
pursuant to Section 2.7, it ceases to be outstanding until the Issuers and the
Trustee receive proof satisfactory to each of them that the replaced Note is
held by a bona fide purchaser.

     If the Trustee or a Paying Agent holds on a Redemption Date, Purchase Date
or Maturity Date money sufficient to pay the principal, premium, if any,
Redemption Price or Purchase Price of, and accrued interest on, Notes payable on
that date, then on and after that date such Notes cease to be outstanding and
interest on them ceases to accrue. Subject to Section 11.6, a Note does not
cease to be outstanding solely because an Issuer or any Affiliate of the Issuers
holds the Note.

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

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

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

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

                                       32

<PAGE>

any, Redemption Price or Purchase Price, and accrued interest thereon, or (ii)
delivered to the Trustee for cancellation.

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

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

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

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

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

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

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

     (a)  The Global Notes 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
B.

                                       33

<PAGE>

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

     (b)  Transfers of Global Notes (including the exchange thereof for Exchange
Notes pursuant to the exchange offer contemplated by Section 2.2) shall be
limited to transfer in whole, but not in part, to the Depository, its successors
or their respective nominees. Interests of beneficial owners in the Global Notes
may be transferred or exchanged for Physical Notes in accordance with the rules
and procedures of the Depository and the provisions of Section 2.15. In
addition, Physical Notes shall be transferred to all beneficial owners in
exchange for their beneficial interests in Global Notes if (i) the Depository
notifies the Issuers that it is unwilling or unable to continue as Depository
for any Global Note and a successor depositary is not appointed by the Company
within 90 days of such notice or (ii) an Event of Default has occurred and is
continuing and the Registrar has received a written request from the Depository
to issue Physical Notes.

     (c)  In connection with any transfer or exchange of a portion of the
beneficial interest in any Global Note to beneficial owners pursuant to
paragraph (b), the Registrar shall (if one or more Physical Notes are to be
issued) reflect on its books and records the date and a decrease in the
principal amount of the Global Note in an amount equal to the principal amount
of the beneficial interest in the Global Note to be transferred, and the Issuers
shall execute, and the Trustee shall, upon receipt of a written order from the
Issuers, authenticate and make available for delivery one or more Physical Notes
of like tenor and amount. In the event that the Physical Notes are not issued to
each such beneficial owner promptly after the Registrar has received a request
from DTC to issued such Physical Notes, the Company expressly acknowledges, with
respect to the right of any Holder to pursue a remedy pursuant to Section 6.6 or
6.7 hereof, the right of any beneficial holder of Notes to pursue such remedy
with respect to the portion of the Global Note that represents such beneficial
holder's Notes as if such Physical Notes had been issued.

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

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

                                       34

<PAGE>

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

Section 2.15.  Special Transfer Provisions.
               ----------------------------

     (a)  Transfers to Non-QIB Institutional Accredited Investors and Non-U.S.
Persons. The following provisions shall apply with respect to the registration

          (i)  the Registrar shall register the transfer of any Note
     constituting a Restricted Security, whether or not such Note bears the
     Private Placement Legend, if (x) the requested transfer is after the date
     such Note may be freely transferable pursuant to Rule 144 of the Securities
     Act or (y) (1) in the case of a transfer to an Institutional Accredited
     Investor which is not a QIB (excluding Non-U.S. Persons), the proposed
     transferee has delivered to the Registrar a certificate substantially in
     the form of Exhibit C hereto or (2) in the case of a transfer to a Non-U.S.
     Person (including a QIB), the proposed transferor has delivered to the
     Registrar a certificate substantially in the form of Exhibit D hereto; and

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

whereupon the Registrar shall reflect on its books and records the date and (if
the transfer does not involve a transfer of outstanding Physical Notes) a
decrease in the principal amount of a Global Note in an amount equal to the
principal amount of the beneficial interest in a Global Note to be transferred,
and (b) the Issuers shall execute and the Trustee shall authenticate and make
available for delivery one or more Physical Notes of like tenor and amount.

     (b)  Transfers to QIBs. The following provisions shall apply with respect

     being made by a proposed transferor who has checked the box provided for on
     the form of Note stating, or has otherwise advised the Issuers and the
     Registrar in writing, that the sale has been made in compliance with the
     provisions of Rule 144A to a transferee who has signed the certification
     provided for on the form of Note stating, or has otherwise advised the
     Issuers and the Registrar in writing, that it is purchasing the Note for
     its own account or an account with respect to which it exercises sole
     investment discretion and that it and any such account is a QIB within the
     meaning of Rule 144A, and is aware that the sale to it is being made in
     reliance on Rule 144A and acknowledges that it has received such
     information regarding the Issuers as it has requested pursuant to Rule 144A
     or has

                                       35

<PAGE>

     determined not to request such information and that it is aware that the
     transferor is relying upon its foregoing representations in order to claim
     the exemption from registration provided by Rule 144A; and

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

     (c)  Private Placement Legend. Upon the transfer, exchange or replacement
of Notes not bearing the Private Placement Legend, the Registrar shall deliver
Notes that do not bear the Private Placement Legend. Upon the transfer, exchange
or replacement of Notes bearing the Private Placement Legend, the Registrar
shall deliver only Notes that bear the Private Placement Legend unless (i) the
circumstances contemplated by paragraph (a)(i)(x) of this Section 2.15 exist,
(ii) there is delivered to the Registrar an Opinion of Counsel reasonably
satisfactory to the Issuers 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 (iii) such Note
has been sold pursuant to an effective registration statement under the
Securities Act and the Registrar has received an Officers' Certificate from the
Issuers to such effect.

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

     The Registrar shall retain copies of all letters, notices and other written
communications received pursuant to Section 2.14 or this Section 2.15. The
Issuers 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 prior written notice to the Registrar.

Section 3.2.   Selection by Trustee of Notes to Be Redeemed.
               ---------------------------------------------

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

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

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

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

principal amount at Stated Maturity equal to the unredeemed portion will be
issued;

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

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

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

     Once the notice of redemption described in Section 3.3 is mailed, Notes
called for redemption become due and payable on the Redemption Date and at the
Redemption Price, plus interest accrued to the Redemption Date. Upon surrender
to the Paying Agent, such Notes shall be paid at the Redemption Price, plus
interest accrued to the Redemption Date, provided that if the Redemption Date is
after a regular interest payment record date and on or prior to the Interest
Payment Date, the accrued interest shall be payable to the Holder of the
redeemed Notes registered on the relevant record date, and provided, further,
that if a Redemption Date is a Legal Holiday, payment shall be made on the next
succeeding Business Day and no interest shall accrue for the period from such
Redemption Date to such succeeding Business Day. Failure to give notice or any
defect in the notice to any Holder shall not affect the validity of the notice
to any other Holder.

Section 3.5.   Deposit of Redemption Price.
               ----------------------------

     On or prior to 10:00 A.M., New York City time, on each Redemption Date, the
Issuers shall deposit with the Paying Agent in immediately available funds money
sufficient to pay the Redemption Price of and accrued interest on all Notes to
be redeemed on that date other than Notes or portions thereof called for
redemption on that date which have been delivered by the Issuers to the Trustee
for cancellation.

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

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

in part, at any time and from time to time, upon not less than 30 nor more than
60 days' notice at a Redemption Price equal to equal to (i) 100% of the Accreted
Value of the notes, plus any accrued and unpaid interest if the Redemption Date
is on or prior to April 30, 2009, or (ii) 100% of the principal

Redemption Price or Purchase Price of, and accrued interest (which shall include
any applicable Additional Interest as provided in the Registration Rights
Agreement) on, the Notes on the dates and in the manner provided in the Notes
and this Indenture. An installment of principal, premium, if any, Redemption
Price or Purchase Price of, or accrued interest on, the Notes shall be
considered paid on the date it is due if the Trustee or a Paying Agent holds on
that date money designated for and sufficient to pay such installment. The
Issuers shall pay interest on overdue principal, premium, if any, Redemption
Price and Purchase Price (including post-petition interest in a proceeding under
any Bankruptcy Law) and overdue interest, to the extent lawful, at the rate
specified in the Notes.

Section 4.2.   SEC Reports.
               ------------

     (a)  Upon the written request of holders of at least 50% of the Notes,
whether or not the Company is subject to Section 13(a) or 15(d) of the Exchange
Act, or any successor provision thereto, the Company will, to the extent
accepted by the SEC and not prohibited under the Exchange Act, file with the SEC
the annual reports, quarterly reports and other documents which the Company
would have been required to file with the SEC pursuant to such Section 13(a) or
15(d) or any successor provision thereto if it were subject to these sections.
The Company will file these documents with the SEC on or prior to the respective
dates (the "Required Filing Dates") by which the Company would have been
required to file them. If filing such documents by the Company with the SEC is
not accepted by the SEC or is prohibited under the Exchange Act, the Company
will promptly upon written request, supply copies of such documents to any
prospective Holder. In addition, the Company will provide and file any
information, reports and documents required to be provided or filed by it under
applicable law.

     (b)  The Issuers will, upon request, provide to any Holder of Notes or any
prospective transferee of any such Holder any information concerning the Issuers

provided, however, that the Issuers shall not be required to furnish such
information in connection with any request made on or after the date which is
two years from the later of (i) the date such Note (or any predecessor Note) was
acquired from the Company or (ii) the date such Note (or any predecessor Note)
was last acquired from an "affiliate" of the Company within the meaning of Rule
144 under the Securities Act.

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

     The Issuers covenant (to the extent that they may lawfully do so) that they
will not at any time insist upon, or plead (as a defense or otherwise) or in any
manner whatsoever claim or take the benefit or advantage of, any stay or
extension law or any usury law or other law which would prohibit or forgive the
Issuers from paying all or any portion of the principal, premium, if any,
Redemption Price or Purchase Price of, and accrued interest on, the Notes as
contemplated herein, wherever enacted, now or at any time hereafter in force, or
which may affect the covenants or the performance of this Indenture and (to the
extent that they may lawfully do so) the Issuers 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.

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

     (a)  The Issuers shall deliver to the Trustee, within 100 days after the

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

     (b)  So long as (and to the extent) not contrary to the then current
recommendations of the American Institute of Certified Public Accountants, the
year-end financial statements delivered pursuant to Section 4.2 above shall be
accompanied by a written statement of each Issuer's independent public
accountants (who shall be a firm of established national reputation) that in
making the examination necessary for certification of such financial statements
nothing has come to their attention which would lead them to believe that the
Issuer has violated any provisions of this Article IV or Article V of this
Indenture or, if any such violation has occurred, specifying the nature and
period of existence thereof, it being understood that such accountants shall not
be liable directly or indirectly for any failure to obtain knowledge of any such
violation.

     (c)  The Issuers will, so long as any of the Notes are outstanding, deliver
to the Trustee, forthwith (and in any event within ten calendar days) upon any
Officer becoming aware of any Default or Event of Default, an Officers'
Certificate specifying such Default or Event of Default and what action the
Issuers are taking or propose to take with respect thereto.

as contested in good faith and by appropriate proceedings.

Section 4.6.   Limitation on Incurrence of Debt.
               ---------------------------------

     (a)  The Company will not, and will not permit any of its Restricted
Subsidiaries to, Incur any Debt, including Acquired Debt, unless immediately
after giving effect to the Incurrence of such Debt and the receipt and
contemporaneous application of the proceeds therefrom, (a) the Interest Coverage
Ratio of the Company and its Restricted Subsidiaries for the last four fiscal
quarters for which financial information is available at the date of
determination (the "Specified Period"), determined on a pro forma basis as if
any such Debt, and any other Debt Incurred since the beginning of the Specified
Period, had been Incurred and the proceeds thereof had been applied at the
beginning of the Specified Period, and any other Debt repaid since the beginning
of the Specified Period had been repaid at the beginning of the Specified
Period, would be greater than 1.75:1 and (b) no Default or Event of Default
shall have occurred and be continuing at the time or as a consequence of the
Incurrence of such Debt.

     (b)  If, during the Specified Period or subsequent thereto and prior to the
date of determination, the Company or any of its Restricted Subsidiaries engage
in any Asset Sale or acquisition, or designate any Restricted Subsidiary to be
an Unrestricted Subsidiary or any Unrestricted Subsidiary to be a Restricted
Subsidiary, EBITDA and Adjusted Interest Expense for the Specified Period shall
be calculated on a pro forma basis giving effect to such Asset Sale or
acquisition or designation, as the case may be, and the application of any
proceeds therefrom as if such Asset Sale or acquisition or designation had
occurred on the first day of the Specified Period.

     (c)  If the Debt which is the subject of a determination under this Section
4.6 is Acquired Debt, or Debt Incurred in connection with the simultaneous
acquisition of any Person, business, Property or assets, or Debt of an
Unrestricted Subsidiary being designated as a Restricted Subsidiary, then such
ratio shall be determined by giving effect on a pro forma basis, as if the
transaction had occurred at the beginning of the Specified Period to both the
Incurrence or assumption of such Acquired Debt or such other Debt by the Company
or any of its Restricted Subsidiaries and the inclusion in EBITDA of the EBITDA
of the acquired Person, business, Property or assets or redesignated Subsidiary.

     (d)  Notwithstanding paragraph (a) above, the Company and its Restricted
Subsidiaries may Incur Permitted Debt.

     (e)  For purposes of determining any particular amount of Debt under this
Section 4.6, (x) Debt Incurred under the Credit Agreement on or prior to the
Issue Date shall be treated as Incurred pursuant to clause (i)(b) of the
definition of "Permitted Debt," (y) Guarantees, Liens or obligations with
respect to letters of credit supporting Debt otherwise included in the
determination of such particular amount shall not be included and (z) any Liens
granted pursuant to the equal and ratable provisions referred to in Section 4.11
shall not be treated as Debt. For

                                       41

<PAGE>

purposes of determining compliance with this Section 4.6, in the event that an
item of Debt meets the criteria of more than one of the types of Debt described
above (other than Debt referred to in clause (x) of the preceding sentence),
including under Section 4.6(a) of this Section 4.6, the Company, in its sole
discretion, shall classify, and from time to time may reclassify, such item of
Debt.

     (f)  The accretion of original issue discount on the Notes and the Existing
15% Notes, any accruals of interest or payment of interest or additional Notes,
shall not be deemed an incurrence of Debt for purposes of this Section 4.6.

Section 4.7.   Limitation on Issuance and Sale of Capital Interests in
               -------------------------------------------------------
               Restricted Subsidiaries.
               ------------------------

     The Company will not permit any Restricted Subsidiary of the Company to
issue any Capital Interest, other than any required directors qualifying shares,
to any person other than the Company or a Wholly-Owned Restricted Subsidiary
thereof. The Company will not sell, and will not permit any of its Restricted
Subsidiaries to sell, any Capital Interests in any Restricted Subsidiary to any
person other than the Company or a Wholly-Owned Restricted Subsidiary unless all
such Capital Interests owned by the Company and its Restricted Subsidiaries are
sold in one or more contemporaneous transactions. In addition, the Company will
not sell any Capital Interest in PHFC to any person other than a Wholly-Owned
Restricted Subsidiary.

Section 4.8.   Limitation on Restricted Payments.
               ----------------------------------

     (a)  The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, make any Restricted Payment unless, at
the time of and after giving effect to the proposed Restricted Payment:

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

          (ii) after giving effect to such Restricted Payment on a pro forma
     basis, the aggregate amount expended or declared for all Restricted
     Payments made on or after the Issue Date shall not exceed the sum, without
     duplication, of (a) 50% of the Adjusted Net Income, or, if Adjusted Net
     Income shall be a deficit, minus 100% of such deficit, of the Company
     accrued on a cumulative basis during the period, taken as one accounting
     period, beginning on the first day of the fiscal quarter in which the
     initial issuance of the Notes occurred and ending on the last day of the
     fiscal quarter immediately preceding the date of such proposed Restricted
     Payment, plus (b) 100% of the aggregate net cash proceeds received by the
     Company after the Issue Date from the issuance and sale, other than to a
     Restricted Subsidiary, of its Qualified Capital Interests, including
     Qualified Capital Interests issued upon the conversion of Debt or
     Redeemable Capital Interests of the Company issued after the Issue Date,
     and from the exercise of options, warrants or other rights to purchase
     Qualified Capital Interests, plus (c) 100% of the net reduction in
     Investments, other than Permitted Investments, after the Issue Date, in any
     Person, resulting from payments of interest on Debt, dividends, repayments
     of loans or advances (but only to the extent such interest, dividends or
     repayments are not included in the calculation of Adjusted Net Income), in
     each case to the Company or any Restricted

                                       42

<PAGE>

     Subsidiary from any Person (including, without limitation, from
     Unrestricted Subsidiaries) or from redesignations of Unrestricted
     Subsidiaries as Restricted Subsidiaries in accordance with this Indenture,
     not to exceed in the case of any Person the amount of Investments
     previously made by the Company or any Restricted Subsidiary in such Person.

     (b)  Notwithstanding paragraph (a) of this Section 4.8, the Company and its
Restricted Subsidiaries may take the following actions, provided that with
respect to clauses (ii), (iii), (iv), (vi) and (vii) of this paragraph (b) of
this Section 4.8, immediately after giving effect to such action, no Default or
Event of Default has occurred and is continuing:

          (i)    the payment of any dividend on Capital Interests in the Company
     or a Restricted Subsidiary within 60 days after declaration thereof if at
     the declaration date such payment would not have been prohibited by the
     foregoing provisions of this Section 4.8;

          (ii)   the retirement of any Qualified Capital Interests of the
     Company or any Restricted Subsidiary by conversion into, or by or in
     exchange for, Qualified Capital Interests, or out of net cash proceeds of
     the substantially concurrent sale (other than to a Subsidiary of the
     Company) of other Qualified Capital Interests of the Company;

          (iii)  the redemption, defeasance, repurchase or acquisition or
     retirement for value of any Debt of the Company that is subordinate in
     right of payment to the Notes out of the net cash proceeds of a
     substantially concurrent issue and sale (other than to a Restricted
     Subsidiary) of new subordinated Debt of the Company Incurred in accordance
     with this Indenture;

          (iv)   payments due under the Permitted Affiliate Agreements that
     would otherwise constitute Restricted Payments, other than pursuant to
     clause (v) below;

          (v)    cash distributions by the Company to its partners on its
     Capital Interests, for so long as it is organized as a partnership or other
     substantially similar pass-through entity for federal income tax purposes,
     in aggregate amounts not exceeding the aggregate amount of Permitted Tax
     Distributions accrued after July 23, 1999;

          (vi)   the purchase, redemption, retirement or other acquisition for
     value of Capital Interests in the Company held by employees or former
     employees of the Company or any Restricted Subsidiary (or their estates or
     beneficiaries under their estates) upon death, disability, retirement,
     termination of employment or pursuant to the terms of any agreement under
     which such Capital Interests were issued; provided that the aggregate cash
     consideration paid for such purchase, redemption, retirement or other
     acquisition of such Capital Interests does not exceed $1,000,000 in any
     fiscal year; and

          (vii)  payments that would otherwise constitute Restricted Payments,
     not to exceed $100,000 in any fiscal year;

          (viii) the purchase of any Warrants;

                                       43

<PAGE>

          (ix)   Guarantees included in Permitted Debt;

          (x)    Restricted Payments not in excess of $5,000,000; and

          (xi)   payments to consummate the Transactions.

     (c)  The actions described in clauses (i), (ii), (iv), (vi) and (vii) of
paragraph (b) of this Section 4.8 shall reduce, without duplication, the amount
that would otherwise be available for Restricted Payments under clause (ii) of
paragraph (a) of this Section 4.8.

     (d)  If the Company makes a Restricted Payment that, at the time of the
making of such Restricted Payment, in the good faith determination of the Board
of Directors of the Company, would be permitted under the requirements of this
Indenture, such Restricted Payment shall be deemed to have been made in
compliance with this Indenture notwithstanding any subsequent adjustment made in
good faith to the Company's financial statements affecting Adjusted Net Income.

     (e)  If any Person in which an Investment that constitutes a Restricted
Payment is made, thereafter becomes a Restricted Subsidiary in accordance with
this Indenture, all such Investments previously made in such Person shall no
longer be counted as Restricted Payments for purposes of calculating the
aggregate amount of Restricted Payments pursuant to clause (ii) of paragraph (a)
of this Section 4.8, in each case to the extent such Investments would otherwise
be so counted.

     (f)  If the Company or a Restricted Subsidiary transfers, conveys, sells,
leases or otherwise disposes of an Investment not in violation of Section 4.9
hereof, which Investment was originally included in the aggregate amount
expended or declared for all Restricted Payments pursuant to clause (c) of the
definition of "Restricted Payments," the aggregate amount expended or declared
for all Restricted Payments shall be reduced by the lesser of (i) the Net Cash
Proceeds from the transfer, conveyance, sale, lease or other disposition of such
Investment or (ii) the amount of the original Investment, in each case, to the
extent originally included in the aggregate amount expended or declared for all
Restricted Payments pursuant to clause (c) of the definition of "Restricted
Payments."

     (g)  For purposes of this Section 4.8, if a particular Restricted Payment
involves a non-cash payment, including a distribution of assets, then such
Restricted Payment shall be deemed to be an amount equal to the cash portion of
such Restricted Payment, if any, plus an amount equal to the Fair Market Value
of the non-cash portion of such Restricted Payment.

     (h)  Notwithstanding anything to the contrary in this Section 4.8, the
Company and its Restricted Subsidiaries may not purchase, redeem, acquire or
retire any Redeemable Capital Interests (including the Class A and Class B
preferred partnership interests in the Company).

Section 4.9.   Limitation on Asset Sales.
               --------------------------

     (a)  The Company will not consummate an Asset Sale unless: (i) the Company
receives consideration at the time of such Asset Sale at least equal to the Fair
Market Value of the Property or assets sold or otherwise disposed of; (ii) at
least 85% of the consideration

                                       44

<PAGE>

received by the Company for such Property or assets consists of cash or Eligible
Cash Equivalents. The amount of any liabilities, as shown on the Company's most
recent balance sheet, of the Company (other than contingent liabilities and
liabilities that are by their terms subordinate to the Notes) that are assumed
or forgiven by the transferee of any such assets will be deemed to be cash for
the purposes of this clause (ii); and (iii) the Net Cash Proceeds received by
the Company are applied, to the extent the Company or any Restricted Subsidiary
elects or is required, either: (A) to repay or purchase and permanently reduce
outstanding Debt of the Company or a Restricted Subsidiary, and to permanently
reduce any commitments in respect thereof; provided, however, that such
repayment and commitment reduction occurs within 270 days following the receipt
of such Net Cash Proceeds; or (B) to an investment in Replacement Assets;
provided, however, that such investment occurs or the Company or such Restricted
Subsidiary enters into contractual commitments to make such investment, subject
only to customary conditions (other than the obtaining of financing), on or
prior to the 270th day following receipt of such Net Cash Proceeds and Net Cash
Proceeds contractually committed are so applied within 365 days following the
receipt of such Net Cash Proceeds. Notwithstanding any provision of this Section
4.9, Asset Swaps and Fuel Hedging Obligations entered into in the ordinary
course of business shall not be subject to clause (ii) of the immediately
preceding sentence.

     (b)  Any Net Cash Proceeds from any Asset Sale that are not used to
reinvest in Replacement Assets and/or repay Debt of the Company or any
Restricted Subsidiary shall constitute "Excess Proceeds."

     (c)  When the aggregate amount of Excess Proceeds exceeds $10,000,000, the
Company shall make an Offer to Purchase from all Holders, Notes (i) having an
aggregate Accreted Value as of the Purchase Date, if the Purchase Date is on or
prior to April 30, 2009, or (ii) in an aggregate principal amount at Stated
Maturity, if the Purchase Date is on or after May 1, 2009, in either case, equal
to the Excess Proceeds, at a Purchase Price in cash equal to: (x) 100% of the
Accreted Value thereof, together with accrued interest, if any, to the Purchase
Date if the Purchase Date is on or prior to April 30, 2009, or (y) 100% of the
principal amount thereof, together with accrued interest, if any, to the
Purchase Date, if the Purchase Date is on or after May 1, 2009.

     (d)  If the aggregate Purchase Price of Notes surrendered by Holders
exceeds the amount equal to the Excess Proceeds, the Trustee shall select the
Notes to be purchased on a pro rata basis. If any amount of Excess Proceeds
remains after completion of such Offer to Purchase, the Company may use such
remaining amount for general corporate purposes, and the amount of Excess
Proceeds shall be reset to zero.

     (e)  On or before the Purchase Date, the Trustee shall, to the extent
lawful, accept for payment, on a pro rata basis or by such other method as the
Trustee shall deem fair and appropriate to the extent necessary, Notes or
portions thereof or beneficial interests under a Global Note properly tendered
pursuant to the Offer to Purchase, deposit with the Paying Agent U.S. legal
tender sufficient to pay the purchase price plus accrued interest, if any, on
the Notes to be purchased and deliver to the Trustee an Officers' Certificate
stating that such Notes or portions thereof were accepted for payment by the
Issuers in accordance with the terms of this Section 4.9. The Paying Agent shall
promptly mail or deliver to each tendering Holder an

                                       45

<PAGE>

amount equal to the Purchase Price of the Note tendered by such Holder and
accepted by the Company for purchase (which payment shall, in the case of the
Holders of interests in the Global Note, be through the facilities of the
Depository), and the Issuers shall promptly issue a new Note, and the Trustee
shall authenticate and mail or make available for delivery such new Note to such
Holder equal in principal amount at Stated Maturity to any unpurchased portion
of the Note surrendered. Any Note not so accepted shall be promptly mailed or
delivered by the Issuers to the Holder thereof. The Company will publicly
announce the results of the Offer to Purchase on the Purchase Date. To the
extent that any amount of Excess Proceeds remains after completion of such Offer
to Purchase, the Company may use such remaining amount for general corporate
purposes, and the amount of Excess Proceeds shall be reset to zero.

     (f)  The Company will comply, to the extent applicable, with the
requirements of Rule 14e-1 under the Exchange Act and other securities laws or
regulations in the event that an Offer to Purchase is required under the
circumstances described therein.

Section 4.10.  Limitation on Transactions with Affiliates.
               ------------------------------------------

     The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, conduct any business or enter into or
permit to exist any transaction or series of related transactions (including,
but not limited to, the purchase, sale or exchange of Property, the making of
any Investment, the giving of any Guarantee or the rendering of any service)
with any Unrestricted Subsidiary or any Affiliate of the Company or any
Restricted Subsidiary other than transactions solely among any of the Company
and its Restricted Subsidiaries (an "Affiliate Transaction") unless: (i) such
business, transaction or series of related transactions is on terms no less
favorable to the Company or such Restricted Subsidiary than those that could be
obtained in a comparable arm's-length transaction between unaffiliated parties;
and (ii) with respect to an Affiliate Transaction involving an amount or having
a value in excess of $1,000,000, the Company delivers to the Trustee an
Officers' Certificate stating that such business, transaction or series of
related transactions complies with clause (i) above. In the case of an Affiliate
Transaction involving an amount or having a value in excess of $3,000,000 but
less than or equal to $10,000,000, the Company must obtain a Board Resolution of
the Board of Directors (including a majority of Disinterested Directors, if any)
certifying that such Affiliate Transaction complies with clause (i) above. In
the case of an Affiliate Transaction involving an amount or having a value in
excess of $10,000,000, the Company must obtain a written opinion of a nationally
recognized investment banking firm or other expert stating that the transaction
is fair to the Company or such Restricted Subsidiary from a financial point of
view. The foregoing limitation does not limit, and shall not apply to, (1) any
transaction or series of related transactions pursuant to the terms of the
Permitted Affiliate Agreements, (2) Restricted Payments and Permitted
Investments permitted under this Indenture, (3) the payment of reasonable and
customary fees to members of the Board of Directors of the Company or a
Restricted Subsidiary who are outside directors, (4) the payment of reasonable
and customary compensation to officers and employees of the Company or any
Restricted Subsidiary as determined by the Board of Directors thereof in good
faith, (5) any transaction pursuant to an agreement, arrangement or
understanding existing on the Issue Date and any amendment to such agreements,
arrangements or understandings that is not adverse to the Company, (6) any
transaction, approved by the Board of Directors of the Company, with an officer
or director of the Company or of any Subsidiary in his or her capacity as
officer or director entered into in the ordinary course of business; and (7)

                                       46

<PAGE>

any transaction pursuant to an agreement, arrangement or understanding with any
Joint Venture Company; provided, however, that any Capital Interests or Debt of
such Joint Venture Company that is beneficially owned by an Affiliate of the
Company shall only be beneficially owned by a Wholly-Owned Restricted Subsidiary
or the Company. The Company may in addition pay advisory fees to an Affiliate of
the Company with respect to specific transactions if such payments would be
permitted under Section 4.8(a). For purposes of this Section 4.10, any
transaction or series of related transactions between the Company or any
Restricted Subsidiary and an Affiliate of the Company that is approved by a
majority of the Disinterested Directors, if any, shall be deemed to comply with
clause (i) above. Notwithstanding the provisions of this Section 4.10, the
Company and its Restricted Subsidiaries are permitted to consummate the
Transactions and to pay fees on the Issue Date in connection with the
consummation of the Transactions.

Section 4.11.  Limitations on Liens.
               --------------------

     (a)  The Company will not create, incur, or otherwise cause or suffer to
exist or become effective any Liens of any kind, other than Permitted Liens,
upon any property or asset of the Company (including, without limitation, any
Capital Interest or Debt of any Restricted Subsidiary), owned by the Company,
unless (i) if such Lien secures Debt which is pari passu with the Notes, then
the Notes are secured on an equal and ratable basis with the obligations so
secured until such time as such obligation is no longer secured by a Lien; or
(ii) if such Lien secures Debt which is subordinated to the Notes, any such Lien
shall be subordinated to the Lien granted to the Holders of the Notes to the
same extent as such subordinated Debt is subordinated to the Notes.

     (b)  Notwithstanding paragraph (a) of this Section 4.11, as long as the
Third Priority Lien is in existence, the Company will not create, incur or
otherwise cause or suffer to exist or become effective any Liens of any kind,
other than the Senior Priority Liens and the Third Priority Lien, upon the
Collateral.

Section 4.13.  Limitation on Creation of Unrestricted Subsidiaries.
               ---------------------------------------------------

     The Company may designate any Subsidiary of the Company to be an
"Unrestricted Subsidiary" as provided below, and such Subsidiary and each other
Person that is then or thereafter becomes a Subsidiary of such Subsidiary will
be deemed to be an Unrestricted Subsidiary. "Unrestricted Subsidiary" means (1)
any Subsidiary designated as such by the Board of Directors of the Company as
described below where (a) neither the Company nor any of its Restricted
Subsidiaries (i) provides credit support for, or Guarantee of, any Debt of such
Subsidiary or any Subsidiary of such Subsidiary including any undertaking,
agreement or instrument evidencing such Debt or (ii) is directly or indirectly
liable for any Debt of such Subsidiary or any Subsidiary of such Subsidiary, and
(b) no default with respect to any Debt of such Subsidiary or any Subsidiary of
such Subsidiary (including any right which the holders thereof may have to take
enforcement action against such Subsidiary) would permit (upon notice, lapse of
time or both) any holder of any other Debt of the Company and its Restricted
Subsidiaries to declare a default on such other Debt or cause the payment
thereof to be

                                       47

<PAGE>

accelerated or payable prior to its final scheduled maturity; and (2) any
Subsidiary of an Unrestricted Subsidiary.

     The Company may designate any Subsidiary (other than the Operating
Partnership or Petro Financial Corporation) to be an Unrestricted Subsidiary
unless such Subsidiary owns any Capital Interests of, or owns or holds any Lien
on any property of, any other Restricted Subsidiary of the Company, provided
that either (x) the Subsidiary to be so designated has total assets of $1,000 or
less or (y) immediately after giving effect to such designation, the Company
could incur at least $1.00 of additional Debt pursuant to paragraph (a) of
Section 4.6 hereof and provided, further, that the Company could make a
Restricted Payment in an amount equal to the greater of the Fair Market Value or
book value of such Subsidiary pursuant to Section 4.8 hereof and such amount is
thereafter treated as a Restricted Payment for the purpose of calculating the
aggregate amount available for Restricted Payments thereunder or (z) such
Subsidiary will be a special purpose entity formed in connection with a new
financing transaction. An Unrestricted Subsidiary may be designated as a
Restricted Subsidiary if (i) all the Debt of such Unrestricted Subsidiary could
be Incurred under Section 4.6 hereof and (ii) all the Liens on the Property and
assets of such Unrestricted Subsidiary could be incurred pursuant to Section
4.11 hereof.

     Any designation of a Restricted Subsidiary of the Company as an
Unrestricted Subsidiary shall be evidenced to the Trustee by filing with the
Trustee a certified copy of the Board Resolution giving effect to such
designation and an Officers' Certificate certifying that such designation
complied with the preceding conditions and was permitted by this Indenture.

Section 4.14.  Limitation on Conduct of Business of PHFC
               -----------------------------------------

Capital Interest of any other Person.

Section 4.15.  Limitation on Capital Expenditures.
               ----------------------------------

     The Company shall not, and shall not permit any Restricted Subsidiary to,

Section 4.16.  [RESERVED].

Section 4.17.  Partnership and Corporate Existence.
               -----------------------------------

     Subject to Article V hereof, the Issuers shall do or cause to be done all
things necessary to preserve and keep in full force and effect their partnership
or corporate existence, and the corporate, partnership or other existence of
each Restricted Subsidiary, in accordance with the respective organizational
documents (as the same may be amended from time to time) of each Restricted
Subsidiary and the rights (charter and statutory), licenses and franchises of
the Company and its Restricted Subsidiaries; provided, however, that the Issuers
shall not be required to preserve any such right, license or franchise, or the
corporate, partnership or other existence of any of its Restricted Subsidiaries
(other than with respect to PHFC), if the Board of Directors shall determine
that the preservation thereof is no longer desirable in the conduct of the

                                       48

<PAGE>

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

Section 4.18.  Change of Control
               -----------------

     (a)  If a Change of Control occurs, the Company will make an Offer to
Purchase all of the outstanding Notes at a Purchase Price in cash equal to (i)
110% of the Accreted Value of the Notes, together with accrued and unpaid
interest, if any, if the Purchase Date is on or prior to April 30, 2009, or (ii)
110% of the principal amount at Stated Maturity of the Notes, together with
accrued and unpaid interest, if any, to the Purchase Date, if the Purchase Date
is on or after May 1, 2009. For purposes of the foregoing, an Offer to Purchase
shall be made within 30 days following the date of the consummation of a
transaction or series of transactions that constitutes a Change of Control. For
purposes of calculating such 30-day period, the running of such period shall be
suspended, for up to a maximum of 30 days, during any period when the
commencement of such Offer to Purchase is delayed or suspended by reason of any
court's or governmental authority's review of or ruling on any materials being
employed by the Company to effect such Offer to Purchase, so long as the Company
has used and continues to use best efforts to make and conclude such Offer to
Purchase promptly, and all Notes properly tendered are purchased on the terms of
such Offer to Purchase.

     In addition, if a Change of Control occurs within one year after a
redemption of the Notes pursuant to Section 3.7, the Company shall pay Holders
of the Notes so redeemed an amount, in cash, equal to 10% of the Accreted Value
(or 10% of principal amount at Stated Maturity if after May 1, 2009) of the
Notes so redeemed. Such amount shall be paid within 30 days of the date such
Change of Control occurs.

     (b)  The Company will not be required to make an Offer to Purchase upon a
Change of Control if a third party makes an Offer to Purchase contemporaneously
with or upon a Change of Control in compliance with the requirements of this
Indenture and purchases all Notes validly tendered and not withdrawn under its
Offer to Purchase.

     (c)  On the Purchase Date, the Company shall, to the extent lawful, (i)
accept for payment Notes or portions thereof or beneficial interests under a
Global Note properly tendered pursuant to the Offer to Purchase, (ii) deposit
with the Paying Agent (by no later than 1:00 p.m. on such date) money sufficient
to pay the Purchase Price of all Notes or portions thereof or beneficial
interests so tendered and (iii) deliver or cause to be delivered to the Trustee
Notes so accepted together with an Officers' Certificate stating the Notes or
portions thereof tendered to the Issuers. The Paying Agent shall promptly (1)
mail to each holder of Notes so accepted and (2) remit to the Depository for
crediting to the respective accounts of the Holders under a Global Note of
beneficial interest so accepted, payment in an amount equal to the purchase
price for such Notes (which payment shall, in the case of the Holders of
beneficial interests in a Global Note, be through the facilities of the
Depository), and the Issuers shall execute and issue, and the Trustee shall
promptly authenticate and mail to such holder, a new Note equal in principal
amount to any unpurchased portion of the Notes surrendered and shall issue a
Global Note equal in principal amount at Stated Maturity to any unpurchased
portion of beneficial interest so surrendered; provided that each such new Note
shall be issued in an original principal amount in denominations of $1,000 and
integral multiples thereof.

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

     (e)  The Company will comply, to the extent applicable, with the
requirements of Rule 14e-1 under the Securities Exchange Act of 1934 and other
securities laws or regulations in connection with any repurchase of the Notes as
described above.

Section 4.19.  Maintenance of Office or Agency.
               -------------------------------

     The Issuers shall maintain in New York, New York an office or agency where
Notes may be surrendered for registration of transfer or exchange or for
presentation for payment and where notices and demands to or upon the Issuers in
respect of the Notes and this Indenture may be served. The Issuers shall give
prompt written notice to the Trustee of the location, and any change in the
location, of such office or agency. If at any time the Issuers shall fail to
maintain any such required office or agency or shall fail to furnish the Trustee
with the address thereof, such presentations, surrenders, notices and demands
may be made or served at the address of the Trustee as set forth in Section
12.2. The Issuers may also from time to time designate one or more other offices
or agencies where the Notes may be presented or surrendered for any or all such
purposes and may from time to time rescind such designations; provided, however,
that no such designation or rescission shall in any manner relieve the Issuers
of their obligation to maintain an office or agency in New York, New York for
such purposes. The Issuers shall give prompt written notice to the Trustee of
such designation or rescission and of any change in the location of any such
other office or agency. The Issuers hereby initially designate the Corporate
Trust Office of the Trustee set forth in Section 12.2 as such office of the
Company.

Section 4.20.  Maintenance of Properties and Insurance.
               ---------------------------------------

     (a)  The Company shall cause all material properties used or useful to the
conduct of its business or the business of any of its Restricted Subsidiaries to
be maintained and kept in good condition, repair and working order (reasonable
wear and tear excepted) and supplied with all equipment deemed necessary in the
good faith judgment of the Officers of the Company and shall cause to be made
all necessary repairs, renewals, replacements, betterments and improvements
thereof; provided, however, that nothing in this Section 4.20 shall prevent the
Company or any Restricted Subsidiary from discontinuing the operation or
maintenance of any of such properties, or disposing of any of them, if such
discontinuance or disposal is in the good faith judgment of the Board of
Directors of the Company or the Restricted Subsidiary concerned,

                                       50

<PAGE>

as the case may be, desirable in the conduct of the business of the Company or
such Restricted Subsidiary, as the case may be, and is not adverse in any
material respect to the Holders.

     (b)  The Company shall provide or cause to be provided, for itself and each
of its Restricted Subsidiaries, insurance (including appropriate self-insurance)
against loss or damage of the kinds that are adequate and appropriate for the
conduct of the business of the Company and such Restricted Subsidiaries in a
prudent manner, with reputable insurers or with the government of the United
States of America or an agency or instrumentality thereof, in such amounts, with
such deductibles, and by such methods as shall be customary, in the good faith
judgment of the Company, for corporations similarly situated in the industry.

               -------------------------------------------------------------
               Lease.
               -----

     (a)  The Company will not, in any transaction or series of transactions,
consolidate with or merge into any other Person, or transfer all or
substantially all of the assets of the Company and its Restricted Subsidiaries,
taken as a whole, to any other Person, unless:

          (i)    either (a) the Company shall be the continuing Person or (b)
     the Person (if other than the Company) formed by such consolidation or
     into which the Company is merged, or the Person that acquires, by sale,
     assignment, conveyance, transfer, lease or disposition, all or
     substantially all of the property and assets of the Company (such Person,
     the "Surviving Entity"), (1) shall be a corporation, partnership, limited
     liability company or similar entity organized and validly existing under
     the laws of the United States, any political subdivision thereof or any
     state thereof or the District of Columbia, and (2) shall expressly assume,
     by a supplemental indenture, the due and punctual payment of all amounts
     due in respect of the principal, premium, if any, Redemption Price,
     Purchase Price and accrued interest on all the Notes and the performance of
     the covenants and obligations of the Company under this Indenture and (3)
     shall expressly assume, by documentation specified by, and executed and
     delivered to, the Trustee (and otherwise acceptable to the Collateral
     Agent), the due and punctual performance of the covenants and obligations
     of the Company under the Security Documents; provided that at any time the
     Company or its successor is a limited partnership, there shall be a
     co-issuer of the Notes that is a corporation;

          (ii)   immediately before and immediately after giving effect to such
     transaction or series of transactions on a pro forma basis (including,
     without limitation, any Debt Incurred or anticipated to be Incurred in
     connection with or in respect of such transaction or series of
     transactions), no Default or Event of Default shall have occurred and be
     continuing or would result therefrom; and

                                       51

          (iii)  immediately after giving effect to such transaction or series
     of transactions on a pro forma basis (including, without limitation, any
     Debt Incurred or anticipated to be Incurred in connection with or in
     respect of such transaction or series of transactions), the Company (or the
     Surviving Entity if the Company is not continuing) shall have a
     Consolidated Net Worth equal to or greater than the Consolidated Net Worth
     of the Company immediately prior to such transaction.

Notwithstanding the foregoing, if, in the good faith determination of the Board
of Directors of the Company, (I) the purpose of such transaction is (A) to
transform the Company into a corporation or (B) to change the state of
organization of the Company or a Restricted Subsidiary, and (II) no material
adverse effect on the creditworthiness of the Company (or the Surviving Entity
if the Company is not continuing) and its Restricted Subsidiaries, taken as a
whole, shall result as a consequence of the transaction, then clause (iii) above
shall not apply; it being recognized that such reorganization shall not be
considered to have a material adverse effect on the creditworthiness of the
Company solely because the Surviving Entity is subject to income taxation.

     Subsidiaries of any Surviving Entity will, upon such transaction or series
of transactions, become Restricted Subsidiaries or Unrestricted Subsidiaries as
provided pursuant to this Indenture and all Debt, and all Liens on property or
assets, of the Surviving Entity and its Subsidiaries that was not Debt, or were
not Liens on Property or assets, of the Company and its Subsidiaries immediately
prior to such transaction or series of transactions shall be deemed to have been
Incurred upon such transaction or series of transactions.

     (b)  In connection with any consolidation, merger or transfer of assets
contemplated by this Section 5.1, the Company shall deliver or cause to be
delivered, to the Trustee, in form and substance reasonably satisfactory to the
Trustee, an Officers' Certificate and an Opinion of Counsel, each stating that
such consolidation, merger, sale, conveyance, assignment, transfer, lease or
other disposition in respect thereto comply with this Section 5.1 and that all
conditions precedent herein provided for relating to such transaction or
transactions have been complied with.

     (c)  The restrictions of Section 5.1(a) and (b) shall not prohibit a merger
of a Restricted Subsidiary into the Company in which the Company is the
continuing person or the merger of a Restricted Subsidiary into or with another
Restricted Subsidiary or another person that as a result of such transaction
becomes a Restricted Subsidiary.

Section 5.2.   Successor Person Substituted.
               ----------------------------

     Upon any transaction or series of transactions that are of the type
described in, and are effected in accordance with, conditions described in
Section 5.1 herein, the Surviving Entity shall succeed to, and be substituted
for, and may exercise every right and power of, the Company or PHFC, as the case
may be, under this Indenture with the same effect as if such Surviving Entity
had been named as the Company or PHFC therein; and when a Surviving Person duly
assumes all of the obligations and covenants of the Company or PHFC, as the case
may be, pursuant to this Indenture and the Notes, except in the case of a lease,
the predecessor Person shall be relieved of all such obligations.

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

     Each of the following is an "Event of Default":

          (1)  default in the payment in respect of the principal of (or
     premium,if any, on) any Note at its maturity (whether at Stated Maturity
     or upon repurchase, acceleration, optional redemption or otherwise);

          (2)  default in the payment of any interest upon any Note when it
     becomes due and payable, and continuance of such default for a period of 30
     days (unless such default in the payment of interest is caused by
     restrictions in the Operating Partnership's ability to distribute funds to
     the Company under the Operating Partnership's Credit Agreement or the
     Operating Partnership's Senior Secured Notes, in which case such default
     must continue for a period of 180 days before it shall constitute an Event
     of Default; provided, however, that in such event, interest shall accrue on
     such interest payment from the date it becomes due and payable until it is
     actually paid at a rate of 14% per annum);

          (3)  default in the making of an Offer to Purchase as required by this
     Indenture;

          (4)  failure to perform or comply with Section 5.1 hereof;

          (5)  default in the performance, or breach, of any covenant or
     agreement of an Issuer in this Indenture (other than a covenant or
     agreement a default in whose performance or whose breach is specifically
     dealt with in (1), (2), (3) or (4) above), and continuance of such default
     or breach for a period of 30 days after written notice thereof has been
     given to the Company by the Trustee or to the Company and the Trustee by
     the Holders of at least 25% in aggregate principal amount at Stated
     Maturity of the outstanding Notes;

          (6)  a default or defaults under any bonds, debentures, notes or other
     evidences of Debt (other than the Notes) by the Company or any Restricted
     Subsidiary having, individually or in the aggregate, a principal or similar
     amount outstanding of at least $5,000,000, whether such Debt now exists or
     shall hereafter be created, which default or defaults shall have resulted
     in the acceleration of the maturity of such Debt prior to its express
     maturity or shall constitute a failure to pay such Debt when due and
     payable after the expiration of any applicable grace period with respect
     thereto;

          (7)  the entry against the Company or any Restricted Subsidiary of a
     final judgment or final judgments for the payment of money in an aggregate
     amount in excess of $5,000,000 by a court or courts of competent
     jurisdiction, which judgments remain

     undischarged, unwaived, unstayed, unbonded or unsatisfied for a period of
     60 consecutive days; or

          (8)  the Company or any Significant Subsidiary pursuant to or within
     the meaning of any Bankruptcy Law:

               (A)  commences a voluntary case,

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

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

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

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

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

               (A)  is for relief against the Company or any Significant
          Subsidiary in an involuntary case,

               (B)  appoints a Custodian of the Company or any Significant
          Subsidiary or for all or substantially all of the property of the
          Company or any Significant Subsidiary, or

               (C)  orders the liquidation of the Company or any Significant
          Subsidiary,

          and, in each case, the order or decree remains unstayed and in effect
     for 60 days; and

          (10) unless all of the Collateral has been released from the Third
     Priority Liens in accordance with the provisions of the Security Documents,
     default by the Company or its Affiliates in the performance of the Security
     Documents which adversely affects the enforceability, validity, perfection
     or priority of the Third Priority Lien on a material portion of the
     Collateral granted to the Collateral Agent for the benefit of the Trustee
     and the Holders, the repudiation or disaffirmation by the Company of its
     material obligations under the Security Documents or the determination in a
     judicial proceeding that the Security Documents are unenforceable or
     invalid against the Company for any reason with respect to a material
     portion of the Collateral (which default, repudiation, disaffirmation or
     determination is not rescinded, stayed, or waived by the Persons having
     such authority pursuant to the Security Documents) or otherwise cured
     within 60 days after the Company receives written notice thereof specifying
     such occurrence from the Trustee or the Holders of at least 25% of the
     outstanding principal amount at Stated Maturity of the Notes and demanding
     that such default be remedied).

                                       54

<PAGE>

     The term "Bankruptcy Law" means Title 11, U.S. Code or any similar Federal
or state law for the relief of debtors. The term "Custodian" means any receiver,
trustee, assignee, liquidator or similar official under any Bankruptcy Law.

     The Trustee may withhold notice to the Holders of the Notes of any Default
(except in payment of principal, Redemption Price or Purchase Price of, and
accrued interest on, the Notes) if the Trustee considers it to be in the best
interest of the Holders of the Notes to do so.

     In the case of any Event of Default occurring by reason of any willful
action (or inaction) taken (or not taken) by or on behalf of the Company with
the intention of avoiding payment of the premium that the Company would have had
to pay if the Company then had elected to redeem the Notes pursuant to Section
3.7(a) hereof, an equivalent premium shall also become and be immediately due
and payable to the extent permitted by law upon the acceleration of the Notes.
If an Event of Default occurs prior to the first date on which the Company could
redeem the Notes pursuant to Section 3.7(a) hereof, by reason of any willful
action (or inaction) taken (or not taken) by or on behalf of the Company with
the intention of avoiding the prohibition on redemption of the Notes prior to
such first date, then the greatest premium specified in Section 3.7(a)
(expressed as a percentage of the principal amount that would otherwise be due)
shall also become immediately due and payable to the extent permitted by law
upon acceleration of the Notes.

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

     If an Event of Default (other than an Event of Default specified in Section
6.1(8) or (9) above) occurs and is continuing, then and in every such case the
Trustee or the Holders of not less than 25% in aggregate principal amount at
Stated Maturity of the outstanding Notes may declare by a notice in writing to
the Company (and to the Trustee if given by Holders), the Notes to be due and
payable immediately in an amount equal to (i) the Accreted Value of the Notes
outstanding on the date of acceleration, together with accrued interest, if any,
to the date of acceleration if such declaration is made on or prior to April 30,
2009, or (ii) the entire principal amount at Stated Maturity of the Notes
outstanding on the date of acceleration plus accrued but unpaid interest if any,
to the date of acceleration, if such declaration is made on or after May 1,
2009. After such acceleration, but before a judgment or decree based on
acceleration, the Holders of a majority in aggregate principal amount at Stated
Maturity of the outstanding Notes may rescind and annul such acceleration if all
existing Events of Default, other than the non-payment of accelerated principal
of, and accrued interest on, the Notes, have been cured or waived as provided in
this Indenture. If an Event of Default specified in Section 6.1(8) or (9) hereof
occurs, the principal of, premium, if any, Redemption Price or Purchase Price
of, and accrued interest on, the Notes then outstanding shall ipso facto become
immediately due and payable without any declaration or other act on the part of
the Trustee or any Holder.

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

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

                                       55

<PAGE>

requested of it as Trustee to settle, compromise, adjust or otherwise conclude
any proceedings to which it is a party. The Trustee may maintain a proceeding
even if it does not possess any of the Notes or does not produce any of them in
the proceeding. A delay or omission by the Trustee or any Holder in exercising
any right or remedy accruing upon an Event of Default shall not impair the right
or remedy or constitute a waiver of or acquiescence in the Event of Default. No
remedy is exclusive of any other remedy. All available remedies are cumulative
to the extent permitted by law.

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

     Subject to Sections 6.2, 6.7 and 8.2 hereof, the Holders of not less than a
majority in aggregate principal amount at Stated Maturity of the outstanding
Notes may on behalf of the Holders of all the Notes waive any past default under
this Indenture and its consequences, except a default (1) in any payment in
respect of the principal, premium, if any, Redemption Price or Purchase Price
of, and accrued interest on, any Notes (including any Note which is required to
have been purchased pursuant to an Offer to Purchase which has been made by the
Issuers), or (2) in respect of a covenant or provision hereof which under this
Indenture cannot be modified or amended without the consent of the Holder of
each outstanding Note affected. Upon any such waiver, such Default shall cease
to exist, and any Event of Default arising therefrom shall be deemed to have
been cured for every purpose of this Indenture, but no such waiver shall extend
to any subsequent or other Default or Event of Default or impair any right
consequence thereto.

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

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

Section 6.6.   Limitation on Suits.
               -------------------

     Subject to Section 6.7 hereof, no Holder of any Note will have any right to
institute any proceeding with respect to this Indenture or for any remedy
thereunder, unless such Holder shall have previously given to the Trustee
written notice of a continuing Event of Default and unless also the Holders of
at least 25% in aggregate principal amount at Stated Maturity of the outstanding
Notes shall have made written request, and offered indemnity reasonably
satisfactory to the Trustee to institute such proceeding as Trustee, and the
Trustee shall not have received from the Holders of a majority in aggregate
principal amount at Stated Maturity of the outstanding Notes a direction
inconsistent with such request and shall have failed to institute

                                       56

<PAGE>

such proceeding within 60 days. A Holder may not use this Indenture to prejudice
the rights of another Holder or to obtain a preference or priority over another
Holder.

Section 6.7.   Rights of Holders to Receive Payment.
               ------------------------------------

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

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

     If an Event of Default in payment of principal, premium, if any, Redemption
Price or Purchase Price of, or accrued interest on, the Notes specified in
Section 6.1(1) or (2) hereof occurs and is continuing, the Trustee may recover
judgment in its own name and as trustee of an express trust against the Issuers
(or any other obligor on the Notes) for the whole amount of unpaid principal,
premium, if any, Redemption Price, Purchase Price of, and accrued interest on,
the Notes remaining unpaid, together with interest on overdue principal,
premium, if any, Redemption Price or Purchase Price, and, to the extent that
payment of such interest is lawful, interest on overdue installments of
interest, in each case at the rate then borne by the Notes, and such further
amounts as shall be sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel, including all sums due and owing to the
Trustee pursuant to Section 7.7.

Section 6.9.   Trustee May File Proofs of Claim.
               --------------------------------

     The Trustee may file such proofs of claim and other papers or documents as
may be necessary or advisable in order to have the claims of the Trustee
(including any claim for the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel) and the Holders allowed in
any judicial proceedings relative to the Issuers (or any other obligor upon the
Notes), their creditors or their property and shall be entitled and empowered to
collect and receive any monies or other property payable or deliverable on any
such claims and to distribute the same after deduction of its reasonable charges
and expenses to the extent that any such charges and expenses are not paid out
of the estate in any such proceedings and any custodian in any such judicial
proceeding is hereby authorized by each Holder to make such payments to the
Trustee, and in the event that the Trustee shall consent to the making of such
payments directly to the Holders, to pay to the Trustee any amount due to it for
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 7.7 hereof. Nothing herein contained shall be deemed to authorize the
Trustee to authorize or consent to or accept or adopt on behalf of any Holder
any plan or reorganization, arrangement, adjustment or composition affecting the
Notes or the rights of any Holder thereof, or to authorize the Trustee to vote
in respect of the claim of any Holder in any such proceedings.

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

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

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

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

     THIRD: to the Issuers.

     The Trustee may fix a record date and payment date for any payment to
Holders pursuant to this Section 6.10.

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

     In any suit for the enforcement of any right or remedy under this Indenture
or in any suit against the Trustee for any action taken or omitted by it as
Trustee, a court in its discretion may require the filing by any party litigant
in the suit of an undertaking to pay the costs of the suit, and the court in its
discretion may assess reasonable costs, including reasonable attorneys' fees 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
pursuant to Section 6.7 hereof or a suit by Holders of more than 10% in
principal amount at Stated Maturity of the Notes then outstanding.

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

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

Section 7.1.   Duties of Trustee.
               -----------------

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

                                       58

<PAGE>

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

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

          (2)  In the absence of bad faith on its part, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness of
     the opinions expressed therein, upon certificates or opinions furnished to
     the Trustee and conforming to the requirements of this Indenture but, in
     the case of any such certificates or opinions which by any provision hereof
     are specifically required to be furnished to the Trustee, the Trustee shall
     be under a duty to examine the same to determine whether or not they
     conform to the requirements of this Indenture (but need not confirm or
     investigate the accuracy of mathematical calculations or other facts stated
     therein).

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

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

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

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

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

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

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

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

     (g)  The Trustee shall not be deemed to have notice of any fact or matter
with respect hereto, including without limitation, the occurrence of a Default
or Event of Default, unless such

                                       59

<PAGE>

fact or matter is actually known by a Trust Officer charged with responsibility
for administering this Indenture or unless in writing received by the Trustee
and making specific reference to this Indenture.

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

     Subject to Section 7.1 hereof:

     (1)   The Trustee may rely conclusively on and shall be fully protected in
acting or refraining from acting upon any document (including without limitation
any Company Request or Officers' Certificate) reasonably believed by it to be
genuine and to have been signed or presented by the proper person. The Trustee
need not investigate any fact or matter stated in any document.

     (2)   Before the Trustee acts or refrains from acting, including whenever
the Trustee deems it desirable that a matter be proved or established prior to
it acting or refraining from acting, it may require an Officers' Certificate or
an Opinion of Counsel, or both, which shall conform to the provisions of Section
12.5 hereof. The Trustee shall be protected and shall not be liable for any
action it takes or omits to take in good faith in reliance on such certificate
or opinion.

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

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

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

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

     (7)   The Trustee shall not be liable for any action taken, suffered, or
omitted to be taken by it in good faith and reasonably believed by it to be
authorized or within the discretion or rights or powers conferred upon it by
this Indenture.

     (8)   In no event shall the Trustee be responsible or liable for special,
indirect, or consequential loss or damage of any kind whatsoever (including, but
not limited to, loss of profit) irrespective of whether the Trustee has been
advised of the likelihood of such loss or damage and regardless of the form of
action.

                                       60

<PAGE>

     (9)   The Trustee shall not be deemed to have notice of any Default or
Event of Default unless a Trust Officer of the Trustee has actual knowledge
thereof or unless written notice of any event which is in fact such a default
is received by the Trustee at the Corporate Trust Office of the Trustee, and
such notice references the Notes and this Indenture.

     (10)  The rights, privileges, protections, immunities and benefits given to
the Trustee, including, without limitation, its right to be indemnified, are
extended to, and shall be enforceable by, the Trustee in each of its capacities
hereunder, and each agent, custodian and other Person employed to act hereunder.

     (11)  the Trustee may request that the Company deliver an Officers'
Certificate (a form of which is attached hereto as Exhibit G) setting forth the
names of individuals and/or titles of officers authorized at such time to take
specified actions pursuant to this Indenture, which Officers' Certificate may be
signed by any person authorized to sign an Officers' Certificate, including any
person specified as so authorized in any such certificate previously delivered
and not superseded.

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

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

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

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

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

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

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

     If required by TIA (S) 313(a), within 60 days after May 15 of any
year, commencing the May 15 following the date of this Indenture, the Trustee
shall mail to each Holder a brief report dated as of such May 15 that complies
with TIA (S) 313(a). The Trustee also shall comply with

                                       61

<PAGE>

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

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

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

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

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

     When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 6.1(9) or (10) hereof occurs, the expenses and the
compensation for the services are intended to constitute expenses of
administration under any Bankruptcy Law.

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

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

     The Trustee may resign by so notifying the Company in writing, such
resignation to become effective upon the appointment of a successor Trustee. The
Holders of a majority in

                                       62

<PAGE>

principal amount at Stated Maturity of the outstanding Notes may remove the
Trustee by notifying the removed Trustee in writing and may appoint a successor
Trustee with the Company's written consent which consent shall not be
unreasonably withheld. The Company may remove the Trustee at its election if:

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

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

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

     (4)  the Trustee otherwise becomes incapable of acting.

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

     If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Issuers or any
Holder of outstanding Notes may petition at the expense of the Company, any
court of competent jurisdiction for the appointment of a successor Trustee. If
the Trustee fails to comply with Section 7.10 hereof, any Holder may petition
any court of competent jurisdiction for the removal of the Trustee and the
appointment of a successor Trustee.

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

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

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

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

     This Indenture shall always have a Trustee who satisfies the requirements
of TIA (S) 310(a)(1), (2) and (5) in every respect. The Trustee shall have a
combined capital and surplus of at least $100,000,000 as set forth in its most
recent published annual report of condition. The Trustee shall comply with TIA
(S) 310(b), including the provision in (S) 310(b)(1); provided that there shall
be excluded from the operation of TIA (S) 310(b)(1) any indenture or indentures
under which other securities, or conflicts of interest or participation in

                                       63

<PAGE>

other securities, of the Issuers are outstanding if the requirements for
exclusion set forth in TIA (S) 310(b)(1) are met.

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

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

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

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

          (a)  that it will hold all sums held by it as agent for the payment of
     principal, premium, if any, Redemption Price or Purchase Price of, and
     accrued interest on, the Notes (whether such sums have been paid to it by
     the Issuers or by any obligor on the Notes) in trust for the benefit of
     Holders of the Notes or the Trustee;

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

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

                        AMENDMENT, SUPPLEMENT AND WAIVER
                        --------------------------------

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

     Without the consent of any Holders, the Issuers and the Trustee, at any
time and from time to time, may enter into one or more indentures supplemental
to this Indenture for any of the following purposes:

     (1)  to evidence the succession of another Person to the Issuers and the
assumption by any such successor of their covenants in this Indenture and in the
Notes; or

     (2)  to add to their covenants for the benefit of the Holders, or to
surrender any right or power herein conferred upon them; or

     (3)  to add additional Events of Default; or

                                       64

<PAGE>

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

     (5)  to evidence and provide for the acceptance of appointment under this
Indenture by a successor Trustee; or

     (6)  to secure the Notes with any additional assets as Collateral; or

     (7)  to cure any ambiguity, to correct or supplement any provision in this
Indenture which may be defective or inconsistent with any other provision in
this Indenture, or to make any other provisions with respect to matters or
questions arising under this Indenture, provided that such actions pursuant to
this clause shall not adversely affect the interests of the Holders in any
material respect; or

     (8)  to issue additional Notes or Exchange Notes (as defined in the
Registration Rights Agreement); or

     (9)  to comply with any requirements of the Commission in order to effect
and maintain the qualification of this Indenture under the Trust Indenture Act;
or

     (10) to release Collateral from the Lien of the Indenture and the Security
Documents when permitted or required by the Security Documents or the Indenture.

     The Trustee is hereby authorized to join with the Issuers in the execution
of any supplemental indenture authorized or permitted by the terms of this
Indenture and to make any further appropriate agreements and stipulations which
may be therein contained, but the Trustee shall not be obligated to enter into
any such supplemental indenture which adversely affects its own rights, duties
or immunities under this Indenture.

Section 8.2.   With Consent of Holders.
               -----------------------

     With the consent of the Holders of not less than a majority at Stated
Maturity in aggregate principal amount at Stated Maturity of the outstanding
Notes, the Issuers and the Trustee may enter into an indenture or indentures
supplemental to this Indenture for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions of this Indenture or
of modifying in any manner the rights of the Holders under this Indenture,
including the definitions herein; provided, however, that except as specifically
provided below, no such supplemental indenture shall, without the consent of the
Holder of each outstanding Note affected thereby:

     (1)  change the Stated Maturity of any Note or of any installment of
interest on any Note, or reduce the amount payable in respect of the Accreted
Value or the principal thereof or the rate of interest thereon or any premium
payable thereon, or reduce the amount that would be due and payable on
acceleration of the maturity thereof, or change the place of payment where, or
the coin or currency in which, any Note or any premium or interest thereon is
payable, or impair the right to institute suit for the enforcement of any such
payment on or after the Stated Maturity thereof; or

                                       65

<PAGE>

     (2)  reduce the percentage in aggregate principal amount at Stated Maturity
of the outstanding Notes, the consent of whose Holders is required for any such
supplemental indenture, or the consent of whose Holders is required for any
waiver (of compliance with certain provisions of this Indenture or certain
defaults thereunder and their consequences) provided for in this Indenture; or

     (3)  modify the obligations of the Issuers to make Offers to Purchase upon
a Change of Control or from the Excess Proceeds of Asset Sales if such
modification was done after or in contemplation of such Change of Control or
such Asset Sale; or

     (4)  subordinate, in right of payment, the Notes to any other Debt of the
Issuers; or

     (5)  modify any of the provisions of this proviso to Section 8.2 or
provisions relating to waiver of defaults or certain covenants contained in
Section 6.2, 6.4 or 6.7 hereof, except to increase any such percentage required
for such actions or to provide that certain other provisions of this Indenture
cannot be modified or waived without the consent of the Holder of each
outstanding Note affected thereby; or

     (6)  release any Guarantees required to be maintained under this Indenture.

     Notwithstanding anything to the contrary herein, with the consent of the
Holders of not less than 75% of the aggregate principal amount at Stated
Maturity of the outstanding Notes, the Issuers and the Trustee may enter into an
indenture or indentures supplemental to the indenture for the purpose of
postponing any interest payment for a period not to exceed three years from the
due date of such postponed interest payment.

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

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

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

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

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

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

                                       66

<PAGE>

revoke the consent as to his Note or portion of a Note, if the Trustee receives
the notice of revocation before the date the modification, amendment,
supplement, waiver or other action becomes effective.

     The Issuers may, but shall not be obligated to, fix a record date for the
purpose of determining the Holders entitled to consent to any modification,
amendment, supplement, or waiver. If a record date is fixed, then,
notwithstanding the preceding paragraph, those Persons who were Holders at such
record date (or their duly designated proxies), and only such Persons, shall be
entitled to consent, to such modification, amendment, supplement, or waiver or
to revoke any consent previously given, whether or not such Persons continue to
be Holders after such record date. No such consent shall be valid or effective
for more than 120 days after such record date unless the consent of the
requisite number of Holders has been obtained. After a modification, amendment,
supplement, waiver or other action becomes effective, it shall bind every
Holder, unless it makes a change described in any of clauses (1) through (6) of
Section 8.2 hereof. In that case, the modification, amendment, supplement,
waiver or other action shall bind each Holder of a Note who has consented to it
and every subsequent Holder of a Note or portion of a Note that evidences the
same debt as the consenting Holder's Note.

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

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

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

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

the obligations referred to in the last paragraph of this Section 9.1 when (1)
either: (A) all Notes theretofore authenticated and delivered have been
delivered to the Trustee for cancellation, or (B) all such Notes not theretofore
delivered to the Trustee for cancellation (i) have become due and payable, or
(ii) will become due and payable within 60 days or are to be called for
redemption within 60 days (a "Discharge") under irrevocable arrangements
satisfactory to the Trustee for the giving of notice of redemption by the
Trustee in the name, and at the expense, of the Issuers, and the Issuers have
irrevocably deposited or caused to be deposited with the Trustee funds in an
amount sufficient to pay and discharge the entire indebtedness on the Notes, not
theretofore delivered to the Trustee for cancellation, for principal, premium,
if any, Redemption Price of, and accrued interest on, the Notes to the date of
deposit or the Stated Maturity or date of redemption; (2) the Issuers have paid
or caused to be paid all other sums then due and payable hereunder by the
Issuers; and (3) the Issuers have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent under this Indenture relating to the Discharge of this Indenture have
been complied with.

     After such delivery the Trustee upon request shall acknowledge in writing
the satisfaction and discharge of the Issuers' obligations under the Notes and
this Indenture except for those surviving obligations specified below.

     Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Issuers in Sections 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 4.19, 9.5,
9.6 and 9.8, the rights, powers, duties and immunities of the Trustee hereunder
(including claims of, or payments to, the Trustee under or pursuant to Section
7.7 hereof), the provisions of Article III and the Trustee's and Paying Agent's
obligations in Section 9.8 shall survive until the Notes are no longer
outstanding. Upon such satisfaction and discharge, only the obligations of the
Issuers in Sections 2.7, 7.7, 9.5, 9.6 and 9.8 hereof shall survive such
satisfaction and discharge.

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

     The Issuers may at their option, by Board Resolution, be discharged from
their obligations with respect to the Notes, on the date the conditions set
forth in Section 9.4 below are satisfied (hereinafter, "Legal Defeasance"). For
this purpose, such Legal Defeasance means that the Issuers shall be deemed to
have paid and discharged the entire indebtedness represented by the Notes and to
have satisfied all their other obligations under such Notes and this Indenture
insofar as such Notes are concerned (and the Trustee, at the expense of the
Issuers, shall, subject to Section 9.6 hereof, execute proper instruments
acknowledging the same), except for the following which shall survive until
otherwise terminated or discharged hereunder: (A) the rights of Holders of
outstanding Notes to receive solely from the trust funds described in Section
9.4 hereof and as more fully set forth in such Section, payments in respect of
the principal, premium, if any, Redemption Price of, or Purchase Price of and
accrued interest on, such Notes when such

payments are due solely from the monies held in trust, (B) the Issuers'

the Trustee hereunder (including claims of, or payments to, the Trustee under or
pursuant to Section 7.7 hereof), (D) Article III and (E) this Article IX.
Subject to compliance with this Article IX, the Issuers may exercise their
option under this Section 9.2 with respect to the Notes notwithstanding the
prior exercise of its option under Section 9.3 below with respect to the Notes.

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

     At the option of the Issuers, pursuant to a Board Resolution, the Issuers
shall be released from their obligations under Sections 4.2 through 4.18 hereof,
inclusive, and Section 4.20, clause (a)(ii) of Section 5.1 hereof (with respect
to Sections 4.2 through 4.18 hereof, inclusive, and Section 4.20), Sections
6.1(3) and 6.1(6), clause (a)(iii) of Section 5.1 hereof, with respect to the
outstanding Notes on and after the date the conditions set forth in Section 9.4
hereof are satisfied (hereinafter, "Covenant Defeasance"), any omission to
comply with such obligations shall not constitute a Default or Event of Default,
and the Notes shall thereafter be deemed not to be outstanding for purposes of
any direction, waiver, consent, declaration or act of the Holders (and the
consequences thereof) in connection with such covenants but shall continue to be
outstanding for all other purposes hereunder. For this purpose, such Covenant
Defeasance means that the Issuers may omit to comply with and shall have no
liability in respect of any term, condition or limitation set forth in any such
specified Section or portion thereof, whether directly or indirectly by reason
of any reference elsewhere herein to any such specified Section or portion
thereof or by reason of any reference in any such specified Section or portion
thereof to any other provision herein or in any other document, but the
remainder of this Indenture and the Notes shall be unaffected thereby.

Section 9.4.   Conditions to Legal Defeasance or Covenant Defeasance.
               -----------------------------------------------------

     The following shall be the conditions to application of Section 9.2 or
Section 9.3 hereof to the outstanding Notes:

     (1)  the Issuers must irrevocably have deposited or caused to be deposited
with the Trustee (or another trustee satisfying the requirements of Section 7.10
hereof who shall agree to comply with the provisions of this Article IX
applicable to it) as trust funds in trust for the purpose of making the
following payments, specifically pledged as security for, and dedicated solely
to the benefits of the Holders of such Notes: (A) money in an amount, or (B)
U.S. Government Obligations, which through the scheduled payment of principal
and interest in respect thereof in accordance with their terms will provide, not
later than the due date of any payment, money in an amount, or (C) a combination
thereof, in each case sufficient without reinvestment, in the opinion of a
nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee, to pay and discharge,
and which shall be applied by the Trustee (or other qualifying trustee) to pay
and discharge, the entire indebtedness in respect of the principal, premium, if
any, Redemption Price of, and accrued interest on, such Notes on the Stated
Maturity thereof or (if the Issuers have made irrevocable arrangements
satisfactory to the Trustee for the giving of notice of redemption by the

                                       69

<PAGE>

Trustee in the name and at the expense of the Issuers) the Redemption Date
thereof, as the case may be, in accordance with the terms of this Indenture and
such Notes;

     (2)  in the case of Legal Defeasance, the Issuers shall have delivered to
the Trustee an Opinion of Counsel stating that (A) the Issuers have received
from, or there has been published by, the Internal Revenue Service a ruling or
(B) since the date of this Indenture, there has been a change in the applicable
federal income tax law, in either case (A) or (B) to the effect that, and based
thereon such opinion shall confirm that, the Holders of such Notes will not
recognize gain or loss for federal income tax purposes as a result of the Legal
Defeasance, deposit and discharge to be effected with respect to such Notes and
will be subject to federal income tax on the same amount, in the same manner and
at the same times as would be the case if such Legal Defeasance, deposit and
discharge were not to occur;

     (3)  in the case of Covenant Defeasance, the Issuers shall have delivered
to the Trustee an Opinion of Counsel to the effect that the Holders of such
outstanding Notes will not recognize gain or loss for federal income tax
purposes as a result of the Covenant Defeasance to be effected with respect to
such Notes and will be subject to federal income tax on the same amount, in the
same manner and at the same times as would be the case if such Covenant
Defeasance were not to occur;

     (4)  no Default or Event of Default with respect to the outstanding Notes
shall have occurred and be continuing at the time of such deposit or, in the
case of Legal Defeasance, either: (A) the Issuers shall have delivered to the
Trustee an Opinion of Counsel to the effect that, based upon existing
precedents, if the matter were properly briefed, a court should hold that the
deposit of moneys and/or U.S. Government Obligations as provided in clause (1)
of this Section 9.4 would not constitute a preference voidable under Section 547
or 548 of the federal bankruptcy laws; or (B) no Default or Event of Default
relating to bankruptcy or insolvency shall have occurred and be continuing at
any time on or prior to the 91st day after the date of such deposit (it being
understood that this condition shall not be deemed satisfied until after such
91st day);

     (5)  such Legal Defeasance or Covenant Defeasance shall not cause the
Trustee to have a conflicting interest within the meaning of the TIA (assuming
all Notes are in default within the meaning of such Act);

     (6)  such Legal Defeasance or Covenant Defeasance shall not result in a
breach or violation of, or constitute a default under, any other agreement or
instrument to which either of the Issuers is a party or by which it is bound;

     (7)  such Legal Defeasance or Covenant Defeasance shall not result in the
trust arising from such deposit constituting an investment company within the
meaning of the Investment Company Act of 1940, as amended, unless such trust
shall be registered under such Act or exempt from registration thereunder; and

     (8)  the Issuers shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent with respect to such Legal Defeasance or Covenant Defeasance have been
complied with.

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

     All money and U.S. Government Obligations (including the proceeds thereof)
deposited with the Trustee pursuant to Section 9.4 hereof in respect of the
outstanding Notes shall be held in trust and applied by the Trustee, in
accordance with the provisions of such Notes and this Indenture, to the payment,
either directly or through any Paying Agent as the Trustee may determine, to the
Holders of such Notes, of all sums due and to become due thereon in respect of
principal, premium, if any, Redemption Price or Purchase Price of, and accrued
interest on, the Notes, but such money need not be segregated from other funds
except to the extent required by law. The Trustee shall be under no duty to
invest such money or U.S. Government Obligations. The Issuers shall pay and
indemnify the Trustee against any tax, fee or other charge imposed on or
assessed against the U.S. Government Obligations deposited pursuant to Section
9.4 hereof or the principal, premium, if any, Redemption Price of, or Purchase
Price of and accrued interest on, the Notes received in respect thereof other
than any such tax, fee or other charge which by law is for the account of the
Holders of the outstanding Notes.

     Anything in this Article IX to the contrary notwithstanding, the Trustee
shall deliver or pay to the Issuers from time to time upon Company Request any
money or U.S. Government Obligations held by it as provided in Section 9.4
hereof which, in the opinion of a nationally-recognized firm of independent
public accountants expressed in a written certification thereof delivered to the
Trustee, are in excess of the amount thereof which would then be required to be
deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

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

     If the Trustee or Paying Agent is unable to apply any money or U.S.
Government Obligations in accordance with Section 9.1, 9.2 or 9.3 hereof by
reason of any legal proceeding or by reason of any order or judgment of any
court or governmental authority enjoining, restraining or otherwise prohibiting
such application, the obligations of the Issuers under this Indenture, the
Notes, shall be revived and reinstated as though no deposit had occurred
pursuant to this Article IX until such time as the Trustee or Paying Agent is
permitted to apply all such money or U.S. Government Obligations in accordance
with Section 9.1 hereof; provided, however, that if the Issuers have made any
payment of principal, premium, if any, Redemption Price of, or Purchase Price of
and accrued interest on, any Notes because of the reinstatement of their
Obligations, the Issuers shall be subrogated to the rights of the Holders of
such Notes to receive such payment from the money or U.S. Government Obligations
held by the Trustee or Paying Agent.

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

     In connection with the satisfaction and discharge of this Indenture, all
moneys then held by any Paying Agent under the provisions of this Indenture
shall, upon demand of the Issuers, be paid to the Trustee, or if sufficient
moneys have been deposited pursuant to Section 9.1 or 9.4 hereof, to the
Issuers, and thereupon such Paying Agent shall be released from all further
liability with respect to such moneys.

                                       71

<PAGE>

Section 9.8.   Moneys Held by Trustee.
               ----------------------

     Any moneys deposited with the Trustee or any Paying Agent or then held by
the Issuers in trust for the payment of the principal, premium, if any,
Redemption Price or Purchase Price of, and accrued interest on, any Note that
are not applied but remain unclaimed by the Holder of such Note for two years
after the date upon which the principal, premium, if any, Redemption Price or
Purchase Price of, and accrued interest on, such Note shall have respectively
become due and payable shall be repaid to the Issuers upon Company Request, or
if such moneys are then held by the Issuers in trust, such moneys shall be
released from such trust; and the Holder of such Note entitled to receive such
payment shall thereafter, as an unsecured general creditor, look only to the
Issuers for the payment thereof, and all liability of the Trustee or such Paying
Agent with respect to such trust money shall thereupon cease; provided, however,
that the Trustee or any such Paying Agent, before being required to make any
such repayment, may, at the expense of the Issuers either mail to each Holder
affected, at the address shown in the register of the Notes maintained by the
Registrar pursuant to Section 2.3 hereof, or cause to be published once a week
for two successive weeks, in a newspaper published in the English language,
customarily published each Business Day and of general circulation in The City
of New York, New York, a notice that such money remains unclaimed and that,
after a date specified therein, which shall not be less than 30 days from the
date of such mailing or publication, any unclaimed balance of such moneys then
remaining will be repaid to the Issuers. After payment to the Issuers, or the
release of any money held in trust by the Issuers, Holders entitled to the money
must look only to the Issuers for payment as general creditors unless applicable
abandoned property law designates another person.

                        COLLATERAL AND SECURITY DOCUMENTS
                        ---------------------------------

Section 10.1.  Collateral and Security Documents.
               ---------------------------------

     (a)  In order to secure the due and punctual payment of the Notes, the
Issuers have entered into the Security Agreement and the other Security
Documents to create a Third Priority Lien on the Collateral in accordance with
the terms thereof. Pursuant to the provisions of the Security Agreement, the
other Security Documents and this Indenture, the rights and remedies of the
Trustee and the Holders of the Notes in the Collateral shall be subordinate and
subject to the rights and remedies of the holders of the Senior Priority Liens
in accordance with the terms of the Security Agreement and the other Security
Documents. In the event of a conflict between the terms of this Indenture and
the Security Documents, the Security Documents shall control.

     (b)  Each Holder of a Note, by accepting such Note, agrees to all of the
terms and provisions of the Security Agreement and the other Security Documents
and authorizes and directs the Trustee to enter into such Security Agreement and
Security Documents.

     (c)  The Issuers shall not, and shall not cause or permit any of their
Restricted Subsidiaries to, intentionally grant a Lien on any of its Collateral
to the Collateral Agent under the Security Documents for the benefit of the
lenders under the Credit Agreement unless a Third

                                       72

<PAGE>

Priority Lien is created in favor of the Collateral Agent for the benefit of the
Trustee (on behalf of the Trustee and the Holders of the Notes) with respect to
such property or assets.

Section 10.2.  Application of Proceeds of Collateral.
               -------------------------------------

     Upon any realization upon the Collateral, the proceeds thereof shall be
applied in accordance with the terms of the Security Agreement.

Section 10.3.  Possession, Use and Release of Collateral.
               -----------------------------------------

     (a)  Unless an Event of Default shall have occurred and be continuing,
subject to the terms of the Security Documents, the Issuers will have the right
to freely operate the Collateral and to collect, invest and dispose of any
income therefrom.

     (b)  Each Holder of a Note, by accepting such Note, acknowledges that (i)
the Security Documents shall provide that so long as any Senior Secured Lien
Obligations (or any commitments or letters of credit in respect thereof) are
outstanding, the holders thereof shall have the exclusive right and authority to
determine the release, sale, or other disposition with respect to the Collateral
and to change, waive or vary the Security Documents, subject in the case of
changes, waivers, or variances, to the conditions specified in the Security
Documents and (ii) the holders of the Senior Secured Lien Obligations may (x)
direct the Collateral Agent to take actions with respect to the Collateral
(including the release of the Collateral and the manner of realization) without
the consent of the Holders or the Trustee and (y) agree to modify the Security
Documents, without the consent of the Holders or the Trustee, to secure
additional Debt and additional secured creditors so long as such modifications
do not expressly violate the provisions of the Credit Agreement or this
Indenture. Subject to the terms of the Security Documents, if at any time or
from time to time Collateral which also secures the Senior Secured Lien
Obligations is released or otherwise disposed of pursuant to the terms of the
relevant governing documents, as applicable, such Collateral securing the Notes
shall be automatically released or disposed of; provided, however, that if an
Event of Default under this Indenture exists as of the date on which the Senior
Secured Lien Obligations are repaid in full, the Collateral securing the Notes
shall not be released until such Event of Default and all other Events of
Default shall have been cured or otherwise waived except to the extent such
Collateral was disposed of in order to repay the Senior Secured Lien
Obligations.

     (c)  At such time as (i) the Senior Secured Lien Obligations have been paid
in full in cash in accordance with the terms thereof, and all commitments and
letters of credit thereunder have been terminated, or (ii) the holders of Senior
Secured Lien have released their Senior Secured Liens on all or any portion of
the Collateral, the Third Priority Liens on the Collateral shall also be
automatically released to the same extent; provided, however, that (A) if an
Event of Default under this Indenture exists, then as of the date on which the
Senior Secured Lien Obligations are repaid in full or terminated as described in
clause (i), the Third Priority Liens on the Collateral shall not be released
except to the extent the Collateral or any portion thereof was disposed of in
order to repay Senior Secured Lien Obligations secured by the Collateral, and
thereafter, the Trustee (acting at the direction of the Holders of a majority of
outstanding principal amount at Stated Maturity of Notes) shall have the right
to direct the Collateral Agent to foreclose upon the Collateral (but in such
event, the Third Priority Liens shall be released

                                       73

<PAGE>

when such Event of Default and all other Events of Default under this Indenture
cease to exist), and (B) if any Senior Secured Lien Obligations (or any portion
thereof) are thereafter secured by the limited partnership interest in the
Operating Partnership owned by the Company that would constitute Collateral, the
Notes shall then be secured by a Third Priority Lien on such Collateral, to the
same extent provided pursuant to the Security Documents as then in effect
immediately prior to the release of the Liens on the Collateral.

     (d)  Notwithstanding the provisions set forth in this Section 10.3, the
Company and its Subsidiaries may, without any release or consent by the
Collateral Agent or the Trustee, perform a number of activities in the ordinary
course in respect of the Collateral to the extent permitted pursuant to the
Security Documents and this Indenture.

Section 10.4.  Opinion of Counsel.
               ------------------

     So long as the Security Documents have not been terminated in accordance
with the terms thereof, the Company shall deliver to the Trustee, so long as
such delivery is required by Section 314(b) of the TIA, on the Issue Date and
thereafter, at least annually, within 30 days of April 1 of each year
(commencing with April 1, 2004), an Opinion of Counsel either stating that in
the opinion of such counsel, such action has been taken with respect to the
recording, filing, recording and refiling of the Indenture or any Security
Document as is necessary to maintain the Security Interests, and reciting the
details of such action, or stating that in the opinion of such counsel, no such
action is necessary to maintain such Security Interests.

Section 10.5.  Further Assurances.
               ------------------

     Each Issuer and each Subsidiary shall, at its own expense, make, execute,
endorse, acknowledge, file and/or deliver to the Collateral Agent from time to
time such lists, descriptions and designations of its Collateral, documents of
title, schedules, confirmatory assignments, conveyances, financing statements,
transfer endorsements, powers of attorney, certificates, reports and other
assurances or instruments and take such further steps relating to the Collateral
and other property or rights covered by the Security Interests, which the
Collateral Agent under the Security Documents deems reasonably appropriate or
advisable to perfect, preserve or protect its Security Interest in the
Collateral.

Section 10.6.  Trust Indenture Act Requirements.
               --------------------------------

     The release of any Collateral from the Third Priority Lien of any of the
Security Documents or the release of, in whole or in part, the Third Priority
Liens created by any of the Security Documents, will not be deemed to impair the
Security Interests in contravention of the provisions hereof if and to the
extent the Collateral or Third Priority Liens are released pursuant to the
applicable Security Documents and pursuant to the terms hereof. Each of the
Holders of the Securities acknowledge that a release of Collateral or Liens
strictly in accordance with the terms of the Security Documents and the terms
hereof will not be deemed for any purpose to be an impairment of the Security
Documents or otherwise contrary to the terms of this Indenture. So long as any
Senior Secured Lien Obligations are outstanding, the Company shall comply with
TIA (S)314(d) relating to the release of property or securities from the Second
Priority Liens hereof but only to the extent required by the TIA.

Section 10.7.  Suits to Protect the Collateral.
               -------------------------------

     Subject to the provisions of the Security Documents, the Trustee shall have
the authority to direct the Collateral Agent to institute and to maintain such
suits and proceedings as the Trustee may deem expedient to prevent any
impairment of the Collateral by any acts which may be unlawful or in violation
of any of the Security Documents or this Indenture, and such suits and
proceedings as the Trustee may deem expedient to preserve or protect its
interests and the interests of the Holders of the Securities in the Collateral
(including suits or proceedings to restrain the enforcement of or compliance
with any legislative or other governmental enactment, rule or order that may be
unconstitutional or otherwise invalid if the enforcement of, or compliance with,
such enactment, rule or order would impair the Security Interests or be
prejudicial to the interests of the Holders of the Securities).

Section 10.8.  Purchaser Protected.
               -------------------

     In no event shall any purchaser in good faith or other transferee of any
property purported to be released hereunder be bound to ascertain the authority
of the Trustee to direct the Collateral Agent to execute the release or to
inquire as to the satisfaction of any conditions required by the provisions
hereof for the exercise of such authority or to see to the application of any
consideration given by such purchaser or other transferee; nor shall any
purchaser or other transferee of any property or rights permitted to be sold by
this Article X, be under obligation to ascertain or inquire into the authority
of any Issuer or any Subsidiary, as applicable, to make any such sale or other
transfer.

Section 10.9.  Powers Exercisable by Receiver or Trustee.
               -----------------------------------------

     In case the Collateral shall be in the possession of a receiver or trustee,
lawfully appointed, the powers conferred in this Article X upon any Issuer or
any Subsidiary, as applicable, with respect to the release, sale or other
disposition of such property may be exercised by such receiver or trustee, and
an instrument signed by such receiver or trustee shall be deemed the equivalent
of any similar instrument of any Issuer or any Subsidiary, as applicable, or of
any officer or officers thereof required by the provisions of this Article X.

Section 10.10. Release upon Termination of Company's Obligations.
               -------------------------------------------------

     In the event that the Company delivers an Officers' Certificate and Opinion
of Counsel certifying that its obligations under this Indenture have been
satisfied and discharged by complying with the provisions of Article IX, the
Trustee shall (i) execute and deliver such releases, termination statements and
other instruments (in recordable form, where appropriate) as any Issuer or any
Subsidiary, as applicable, may reasonably request to evidence the termination of
the Security Interests created by the Security Documents and (ii) not be deemed
to hold the Security Interests for its benefit and the benefit of the Holders of
the Securities.

Section 12.4.  Certificate and Opinion as to Conditions Precedent.
               --------------------------------------------------

     Upon any request or application by the Issuers to the Trustee to take any
action under this Indenture, the Issuers shall furnish to the Trustee at the
request of the Trustee:

          1.   an Officers' Certificate (which shall include the statements set
               forth in Section 12.5 below) in form and substance reasonably
               satisfactory to the Trustee stating that, in the opinion of the
               signers, all conditions precedent, if any, provided for in this
               Indenture relating to the proposed action have been complied
               with;

               and

          2.   an Opinion of Counsel (which shall include the statements set
               forth in Section 12.5 below) in form and substance reasonably
               satisfactory to the Trustee stating that, in the opinion of such
               counsel, all such conditions precedent have been complied with.

Section 12.5.  Statements Required in Certificate and Opinion.
               -----------------------------------------------

     Each certificate and opinion with respect to compliance with a condition or
covenant provided for in this Indenture shall include:

          1.   a statement that the Person making such certificate or opinion
               has read such covenant or condition;

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

                                       77

<PAGE>

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

          4.   a statement as to whether or not, in the opinion of such Person,
               such covenant or condition has been complied with.

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

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

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

Section 12.6.  When Treasury Notes are Disregarded.
               ------------------------------------

     In determining whether the Holders of the required aggregate principal
amount at Stated Maturity of Notes have concurred in any direction, waiver or
consent, Notes owned by the Issuers or any other obligor on the Notes or by any
Affiliate of any of them shall be disregarded as though they were not
outstanding, except that for the purposes of determining whether the Trustee
shall be protected in relying on any such direction, waiver or consent, only
Notes which a Trust Officer of the Trustee actually knows are so owned shall be
so disregarded. Notes so owned which have been pledged in good faith shall not
be disregarded if the pledgee establishes to the satisfaction of the Trustee the
pledgee's right so to act with respect to the Notes and that the pledgee is not
an Issuer or any other obligor upon the Notes or any Affiliate of any of them.

Section 12.7.  Rules by Trustee and Agents.
               ----------------------------

     The Trustee may make reasonable rules for action by or meetings of Holders
and any Registrar or Paying Agent may make reasonable rules for their functions
provided that no such rule shall conflict with the terms of this Indenture or
the TIA.
