                                   ARTICLE II

                                 THE DEBENTURES

     SECTION 2.01. Form and Dating. (a) The Initial Debentures issued on the
date hereof and the Trustee's certificate of authentication shall be
substantially in the form of Exhibit A, which is hereby incorporated in and
expressly made a part of this Indenture, and as otherwise provided in this
Article II. Any Additional Debentures shall be issued in the form of Exhibit A,
if such Debenture is issued other than pursuant to an effective registration
statement under the Securities Act (each Debenture issued substantially in the
form of Exhibit A being hereafter referred to as a "Restricted Debenture"). The
Debentures may have notations, legends or endorsements required by law, stock
exchange rule, agreements to which the Issuer or any Guarantor is subject, if
any, or usage; provided that any such notation, legend or endorsement is in a
form acceptable to the Issuer; and provided, further, that no Debenture may be
issued without the Restricted Transfer Legend. Each Debenture shall be

                                      -16-
<PAGE>
dated the date of its authentication. The terms of the Debentures set forth in
Exhibit A are part of the terms of this Indenture. The Debentures shall be
issuable only in registered form without coupons and only in denominations of
$1,000 and integral multiples thereof.

     (b) The Debentures issued on the date hereof and at each subsequent Closing
are being offered and sold by the Issuer pursuant to subscription agreements
(each a "Subscription Agreement"). Unless an offering of Debentures is
registered under the Securities Act, the Debentures will be offered and sold by
the Issuer only (i) to "Accredited Investors" (within the meaning of Rule 501
under the Securities Act) ("Accredited Investors") and (ii) in reliance on
Regulation S under the Securities Act ("Regulation S"). After such initial
offers and sales, Debentures that are Restricted Debentures may be transferred
in reliance on Regulation S and to Accredited Investors in accordance with
certain transfer restrictions. Initial Debentures issued on a Closing Date and
Additional Debentures shall be issued in the form of permanent certificated
securities in registered form in substantially the form set forth in Exhibit A
attached hereto (the "Physical Debentures").

     (c) All Debentures issued hereunder, including the Initial Debentures and
any Additional Debentures, shall be treated as a single class of securities
under this Indenture.

     SECTION 2.02. Execution and Authentication. One or more Officers of the
General Partner shall sign the Debentures by manual or facsimile signature.

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

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

     The Trustee shall authenticate and make available for delivery upon a
written order of the General Partner signed by two of its Officers Debentures
for original issue on the date hereof and on subsequent Issue Dates in an
aggregate principal amount of up to $25,000,000. Such order shall specify the
amount of the Debentures to be authenticated, and the date on which the original
issue of Debentures is to be authenticated. The aggregate principal amount of
Debentures outstanding at any time may not exceed $25,000,000 except as provided
in Section 2.07.

     The Trustee may appoint an authenticating agent reasonably acceptable to
the Issuer to authenticate the Debentures. Any such appointment shall be
evidenced by an instrument signed by a Trust Officer of the Trustee, a copy of
which shall be furnished to the Issuer. Unless limited by the terms of such
appointment, an authenticating agent may authenticate

                                      -17-
<PAGE>
Debentures whenever the Trustee may do so. After any such appointment, each
reference in this Indenture to authentication by the Trustee includes
authentication by such agent. An authenticating agent has the same rights as any
Registrar, Paying Agent or agent for service of notices and demands.

     SECTION 2.03. Registrar and Paying Agent. The Issuer shall maintain an
office or agency where Debentures may be presented for registration of transfer
or for exchange (the "Registrar") and an office or agency where Debentures may
be presented for payment (the "Paying Agent"). The Registrar shall keep a
register of the Debentures and of their transfer and exchange. The Issuer may
have one or more co-registrars and one or more additional paying agents. The
term "Paying Agent" includes any additional paying agent.

     The Issuer 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
Issuer shall fail to maintain any such required office or agency or shall fail
to furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the address of the Trustee set
forth in Section 14.02.

     The Issuer may also from time to time designate one or more other offices
or agencies where the Debentures may be presented or surrendered for any or all
such purposes and may from time to time rescind such designations. The Issuer
will give prompt notice to the Trustee of any such designation or rescission and
of any change in the location of any such other office or agency.

     The Issuer initially designates the Corporate Trust Office of the Trustee
specified in Section 14.02 as such office of the Issuer in accordance with this
Section 2.03.

     The Issuer shall enter into an appropriate agency agreement with any
Registrar, Paying Agent or co-registrar not a party to this Indenture, which
shall incorporate the terms of the TIA. The agreement shall implement the
provisions of this Indenture that relate to such agent. The Issuer shall notify
the Trustee of the name and address of any such agent. If the Issuer fails to
maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be
entitled to appropriate compensation therefor pursuant to Section 7.07. Either
the Issuer or any domestically organized Wholly Owned Restricted Subsidiary may
act as Paying Agent, Registrar, co-registrar or transfer agent.

     The Issuer initially appoints the Trustee as Registrar and Paying Agent in
connection with the Debentures.

     The Issuer may remove any Registrar or Paying Agent upon written notice to
such Registrar or Paying Agent and to the Trustee, provided that no such removal
shall become

                                      -18-
<PAGE>
effective until payment to the Registrar or Paying Agent of any fees due to
either of them from the Issuer, other than fees which are currently being
contested in good faith, and (1) acceptance of an appointment by a successor as
evidenced by an appropriate agreement entered into by the Issuer and such
successor Registrar or Paying Agent, as the case may be, and delivered to the
Trustee or (2) notification to the Trustee that the Trustee shall serve as
Registrar or Paying Agent until the appointment of a successor in accordance
with clause (1) above. The Registrar or Paying Agent may resign at any time upon
not less than three Business Days' prior written notice to the Issuer; provided,
however, that the Trustee may resign as Paying Agent or Registrar only if the
Trustee also resigns as Trustee in accordance with Section 7.08.

     SECTION 2.04. Paying Agent To Hold Money in Trust. Prior to 10:00 a.m. on
each due date of the principal and interest on any Debenture, the Issuer shall
deposit with the Paying Agent (or if the Issuer or a permitted Wholly Owned
Restricted Subsidiary is acting as Paying Agent, segregate and hold in trust for
the benefit of the Persons entitled thereto) a sum sufficient to pay such
principal and interest when so becoming due. The Issuer shall require each
Paying Agent (other than the Trustee) to agree in writing that the Paying Agent
shall hold in trust for the benefit of Debentureholders or the Trustee all money
held by the Paying Agent for the payment of principal of or interest on the
Debentures and shall notify the Trustee in writing of any default by the Issuer
in making any such payment within one Business Day thereof. If the Issuer or a
permitted Wholly Owned Restricted Subsidiary acts as Paying Agent, it shall
segregate the money held by it as Paying Agent and hold it as a separate trust
fund. The Issuer at any time may require a Paying Agent to pay all money held by
it to the Trustee and to account for any funds disbursed by the Paying Agent.
Upon complying with this Section, the Paying Agent shall have no further
liability for the money delivered to the Trustee.

     Any money deposited with any Paying Agent, or then held by the Issuer or a
permitted Wholly Owned Restricted Subsidiary in trust for the payment of
principal or interest on any Debenture and remaining unclaimed for two years
after such principal and interest has become due and payable shall be paid to
the Issuer at its request, or, if then held by the Issuer or a permitted Wholly
Owned Restricted Subsidiary, shall be discharged from such trust; and the
Debentureholders shall thereafter, as general unsecured creditors, look only to
the Issuer for payment thereof, and all liability of the Paying Agent with
respect to such money, and all liability of the Issuer or such permitted Wholly
Owned Restricted Subsidiary as trustee thereof, shall thereupon cease.

     SECTION 2.05. Debentureholder Lists. The Trustee shall preserve in as
current a form as is reasonably practicable the most recent list available to it
of the names and addresses of Debentureholders. If the Trustee is not the
Registrar, the Issuer shall furnish, or cause the Registrar to furnish, to the
Trustee, in writing at least five Business Days before

                                      -19-
<PAGE>
each interest payment date and at such other times as the Trustee may request in
writing, a list in such form and as of such date as the Trustee may reasonably
require of the names and addresses of Debentureholders.

     SECTION 2.06. Transfer and Exchange. Transfers of Debentures are restricted
in accordance with Section 2.13. The Debentures shall be issued in registered
form and shall be transferable only upon the surrender of a Debenture for
registration of transfer. When a Debenture is presented to the Registrar or a
co-registrar with a request to register a transfer, the Registrar shall register
the transfer as requested if the following requirements (and any additional
requirements imposed by any amendments to Section 8.401 of the Uniform
Commercial Code or any replacement or successor section) are met: (i) the Person
seeking registration of transfer is eligible to have the Debenture registered in
the name of the Person; (ii) the indorsement or instruction for transfer is made
by the appropriate Person or by an agent who has actual authority to act on
behalf of the appropriate Person; (iii) reasonable assurance is given the
Registrar that the indorsement or instruction is genuine and authorized; (iv)
any applicable law relating to the collection of taxes has been complied with;
(v) the transfer does not violate the Restricted Debentures Legend or the
Restricted Transfer Legend; (vi) a demand that the Issuer or the Registrar not
register the transfer has not become effective under Section 8.403 of the UCC,
or the Issuer has complied has complied with Section 8.403(b) of the UCC but no
legal process or indemnity bond is obtained as provided in Section 8.403(d) of
the UCC; and (vii) the transfer is in fact rightful or is to a protected
purchaser as defined in Section 8.303 of the UCC (a "protected purchaser"). When
a Debenture is presented to the Registrar or a co-registrar with a request to
exchange them for an equal principal amount of Debentures of other
denominations, the Registrar shall make the exchange as requested if the same
requirements are met. To permit registration of transfers and exchanges, the
Issuer shall execute and the Trustee shall authenticate Debentures at the
Registrar's or co-registrar's request. The Issuer may require payment of a sum
sufficient to pay all taxes, assessments or other governmental charges in
connection with any transfer or exchange pursuant to this Section.

     Prior to the due presentation for registration of transfer of any
Debenture, the Issuer, the Guarantors, the Trustee, the Paying Agent, the
Registrar or any co-registrar may deem and treat the Person in whose name a
Debenture is registered as the absolute owner of such Debenture for the purpose
of receiving payment of principal of and accrued and unpaid interest, if any, on
such Debenture and for all other purposes whatsoever, whether or not such
Debenture is overdue, and none of the Issuer, the Trustee, the Paying Agent, the
Registrar or any co-registrar shall be affected by notice to the contrary.

     All Debentures issued upon any transfer or exchange pursuant to this
Section 2.06 will evidence the same debt and will be entitled to the same
benefits under this Indenture as the Debentures surrendered upon such transfer
or exchange.

                                      -20-
<PAGE>
     The Trustee shall have no obligation or duty to monitor, determine or
inquire as to compliance with any restrictions on transfer imposed under this
Indenture or under applicable law with respect to any transfer of any interest
in any Debenture other than to require delivery of such certificates and other
documentation or evidence as are expressly required by, and to do so if and when
expressly required by the terms of, this Indenture, and to examine the same to
determine substantial compliance as to form with the express requirements
hereof.

     SECTION 2.07. Replacement Debentures. If a mutilated Debenture is
surrendered to the Registrar or if the Holder of a Debenture claims that the
Debenture has been lost, destroyed or wrongfully taken, the Issuer shall issue
and the Trustee shall authenticate a replacement Debenture if the Holder (i)
satisfies the Issuer or the Trustee within a reasonable time after he has notice
of such loss, destruction or wrongful taking and the Registrar does not register
a transfer prior to receiving such notification, (ii) makes such request to the
Issuer or the Trustee prior to the Debenture being acquired by a protected
purchaser and (iii) satisfies any other reasonable requirements of the Trustee
and the Issuer including evidence of the destruction, loss or theft of the
Debenture. Such Holder shall furnish an indemnity bond sufficient in the
judgment of the Trustee to protect the Issuer, the Trustee, the Paying Agent,
the Registrar and any co-registrar from any loss that any of them may suffer if
a Debenture is replaced. The Issuer and the Trustee may charge the Holder for
their expenses in replacing a Debenture including the payment of a sum
sufficient to cover any tax or other governmental charge that may be required.
In the event any such mutilated, lost, destroyed or wrongfully taken Debenture
has become or is about to become due and payable, the Issuer in its discretion
may pay such Debenture instead of issuing a new Debenture in replacement
thereof.

     Every replacement Debenture is an additional obligation of the Issuer.

     The provisions of this Section 2.07 are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the replacement
or payment of mutilated, lost, destroyed or wrongfully taken Debentures.

     SECTION 2.08. Outstanding Debentures. Debentures outstanding at any time
are all Debentures authenticated by the Trustee except for those canceled by it,
those delivered to it for cancellation and those described in this Section as
not outstanding. A Debenture does not cease to be outstanding because the Issuer
or an Affiliate of the Issuer holds the Debenture.

     If a Debenture is replaced pursuant to Section 2.07, it ceases to be
outstanding unless the Trustee and the Issuer receive proof satisfactory to them
that the replaced Debenture is held by a protected purchaser.

                                      -21-
<PAGE>
     If the Paying Agent segregates and holds in trust, in accordance with this
Indenture, on a maturity date money sufficient to pay all principal and interest
payable on that date with respect to the Debentures (or portions thereof)
maturing, and the Paying Agent is not prohibited from paying such money to the
Debentureholders on that date pursuant to the terms of this Indenture, then on
and after that date such Debentures (or portions thereof) cease to be
outstanding and interest on them ceases to accrue.

     SECTION 2.09. Temporary Debentures. Until Definitive Debentures are ready
for delivery, the Issuer may prepare and the Trustee shall authenticate
temporary Debentures. Temporary Debentures shall be substantially in the form of
Definitive Debentures but may have variations that the Issuer considers
appropriate for temporary Debentures. Without unreasonable delay, the Issuer
shall prepare and the Trustee shall authenticate Definitive Debentures and
deliver them in exchange for temporary Debentures upon surrender of such
temporary Debentures at the office or agency of the Issuer, without charge to
the Holder.

     SECTION 2.10. Cancellation. The Issuer at any time may deliver Debentures
to the Trustee for cancellation. The Registrar and the Paying Agent shall
forward to the Trustee any Debentures surrendered to them for registration of
transfer, exchange or payment. The Trustee and no one else shall cancel all
Debentures surrendered for registration of transfer, exchange, payment or
cancellation and deliver canceled Debentures to the Issuer in accordance with
the Trustee's customary procedures. The Issuer may not issue new Debentures to
replace Debentures they have paid or delivered to the Trustee for cancellation.
The Trustee shall not authenticate Debentures in place of canceled Debentures
other than pursuant to the terms of this Indenture.

     SECTION 2.11. Defaulted Interest. If the Issuer defaults in a payment of
interest on the Debentures, the Issuer shall pay the defaulted interest (plus
interest on such defaulted interest to the extent lawful) in any lawful manner.
The Issuer may pay the defaulted interest to the persons who are
Debentureholders on a subsequent special record date. The Issuer shall fix or
cause to be fixed any such special record date and payment date to the
reasonable satisfaction of the Trustee and shall promptly mail or cause to be
mailed to each Debentureholder a notice that states the special record date, the
payment date and the amount of defaulted interest to be paid.

     The Issuer may make payment of any defaulted interest in any other lawful
manner not inconsistent with the requirements (if applicable) of any Debentures
exchange on which the Debentures may be listed, and upon such notice as may be
required by such exchange, if, after notice given by the Issuer to the Trustee
of the proposed payment pursuant to this paragraph, such manner of payment shall
be deemed practicable by the Trustee.

                                      -22-
<PAGE>
     SECTION 2.12. CUSIP Numbers. The Issuer in issuing the Debentures may use
"CUSIP" numbers (if then generally in use); provided, however, that no
representation is made as to the correctness of such numbers either as printed
on the Debentures, and reliance may be placed only on the other identification
numbers printed on the Debentures. The Issuer will promptly notify the Trustee
of any change in "CUSIP" numbers.

     SECTION 2.13. Special Transfer Restrictions and Provisions. Debentures, or
beneficial interests therein, shall not be transferable without the prior
written consent of the General Partner, which consent may be withheld in the
General Partner's discretion. In addition, unless and until a Restricted
Debenture is transferred or exchanged under an effective registration statement
under the Securities Act, the following provisions shall apply:

     (a) Transfers to Accredited Investors. The following provisions shall apply
with respect to the registration of any proposed transfer of a Restricted
Debenture to any Accredited Investor (other than pursuant to Regulation S):

               (i) The Registrar shall register the transfer of any Restricted
          Debenture by a Holder if (x) the requested transfer is (I) at least
          two years after the later of (A) the Issue Date with respect to such
          Restricted Debenture and (B) the date such Restricted Debenture was
          acquired from an affiliate of the Issuer and (II) at least three
          months after the last date such Holder was an affiliate of the Issuer
          or (y) the proposed transferee has delivered to the Registrar a letter
          substantially in the form set forth in Exhibit C hereto.

     (b) Transfers Pursuant to Regulation S. If a Holder proposes to transfer a
Restricted Debenture pursuant to Regulation S, then the Registrar shall register
any such proposed transfer if (x) the requested transfer is at least two years
after the Issue Date with respect to such Restricted Debenture and at least
three months after the last date such Holder was a affiliate of the Issuer or
(y) upon receipt of a letter substantially in the form of Exhibit D hereto from
the proposed transferor and receipt of a letter substantially in the form of
Exhibit E hereto from the proposed transferee.

     (c) Restricted Debentures Legend. Upon the transfer, exchange or
replacement of Debentures bearing the Restricted Debentures Legend, the
Registrar shall deliver only Debentures that bear the Restricted Debentures
Legend unless either (i) the circumstances contemplated by paragraph (a)(i)(x)
of this Section exist or (ii) there is delivered to the Registrar an Opinion of
Counsel reasonably satisfactory to the Issuer 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.

                                      -23-
<PAGE>
     (d) General. By its acceptance of any Debenture, each Holder of such a
Debenture acknowledges the restrictions on transfer of such Debenture set forth
in this Indenture and in the Restricted Debentures Legend and Restricted
Transfer Legend, and agrees that it shall transfer such Debenture or a
beneficial interest therein only as provided in this Indenture.

     The Registrar shall retain copies of all letters, notices and other written
communications received pursuant to this Section 2.13. The Issuer shall have the
right to inspect and make copies of all such letters, notices or other written
communications at any reasonable time upon the giving of reasonable written
notice to the Registrar.

                                   ARTICLE III

                                   REDEMPTION

     SECTION 3.01. Notices to Trustee. If the Issuer elects to redeem Debentures
pursuant to Section 3.07, it shall notify the Trustee in writing of the
redemption date, the principal amount of Debentures to be redeemed and the
paragraph of the Debentures pursuant to which the redemption will occur.

     The Issuer shall give each notice to the Trustee provided for in this
Section at least 60 days before the redemption date unless the Trustee consents
to a shorter period. Such notice shall be accompanied by an Officers'
Certificate and an Opinion of Counsel from the Issuer to the effect that such
redemption will comply with the conditions herein. If fewer than all the
Debentures are to be redeemed, the record date relating to such redemption shall
be selected by the Issuer and given to the Trustee, which record date shall be
not fewer than 15 days after the date of notice to the Trustee. Any such notice
may be canceled at any time prior to notice of such redemption being mailed to
any Holder and shall thereby be void and of no effect.

     SECTION 3.02. Selection. If less than all of the Debentures are to be
redeemed at any time, selection of Debentures for redemption will be made by the
Trustee in compliance with the requirements of the principal national exchange,
if any, on which the Debentures are listed, or, if the Debentures are not so
listed, on a pro rata basis, by lot or by such method as the Trustee shall deem
fair and appropriate; provided, however, that if a partial redemption is made
with the proceeds of a public offering of common stock, selection of the
Debentures or portions thereof for redemption shall be made by the Trustee on a
pro rata basis only or on as nearly a pro rata basis as is practicable, unless
such method is otherwise prohibited. If any Debenture is to be redeemed in part
only, the notice of redemption that relates to such Debenture shall state the
portion of the principal amount thereof to be redeemed. On and after

                                      -24-
<PAGE>
the redemption date, interest ceases to accrue on Debentures or portions of them
called for redemption.

     SECTION 3.03. Notice. Notices of redemption shall be mailed by first class
mail at least 30 but not more than 60 days before the redemption date to each
Holder of Debentures to be redeemed at its registered address. Notices of
redemption may not be conditional. The Trustee shall notify the Issuer promptly
of the Debentures or portions of Debentures to be redeemed.

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

          (1) the redemption date;

          (2) the redemption price;

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

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

          (5) if fewer than all the outstanding Debentures are to be redeemed,
     the certificate numbers and principal amounts of the particular Debentures
     to be redeemed;

          (6) that, unless the Issuer defaults in making such redemption payment
     or the Paying Agent is prohibited from making such payment pursuant to the
     terms of this Indenture, interest on Debentures (or portion thereof) called
     for redemption ceases to accrue on and after the redemption date;

          (7) the paragraph of the Debentures pursuant to which the Debentures
     called for redemption are being redeemed;

          (8) the CUSIP number, if any, printed on the Debentures being
     redeemed; and

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

     At the Issuer's request (which may be revoked at any time in writing prior
to the time at which the Trustee shall have given such notice to the Holders),
the Trustee shall give the notice of redemption in the Issuer's name and at the
Issuer's expense. In such event, the Issuer shall provide the Trustee with the
information required by this Section.

                                      -25-
<PAGE>
     SECTION 3.04. Effect of Notice of Redemption. Once notice of redemption is
mailed, Debentures called for redemption become due and payable on the
redemption date and at the redemption price stated in the notice. Upon surrender
to the Paying Agent, such Debentures shall be paid at the redemption price
stated in the notice, plus accrued interest to the redemption date; provided
that if the redemption date is after a regular record date and on or prior to
the interest payment date, the accrued interest shall be payable to the
Debentureholder of the redeemed Debentures registered on the relevant record
date. If mailed in the manner herein, the notice shall be conclusively presumed
to have been given whether or not the Holder receives such notice. 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 3.05. Deposit of Redemption Price. Prior to 10:00 a.m. on the
redemption date, the Issuer shall deposit with the Paying Agent (or, if the
Issuer or a Wholly Owned Restricted Subsidiary is the Paying Agent, shall
segregate and hold in trust) money sufficient to pay the redemption price of and
accrued interest on all Debentures to be redeemed on the redemption date other
than Debentures or portions of Debentures called for redemption that have been
delivered by the Issuer to the Trustee for cancellation.

     SECTION 3.06. Debentures Redeemed in Part. Upon surrender of a Debenture
that is redeemed in part, the Issuer shall execute and the Trustee shall
authenticate for the Holder (at the Issuer's expense) a new Debenture equal in
principal amount to the unredeemed portion of the Debenture surrendered.

     SECTION 3.07. Optional Redemption. The Debentures may not be redeemed prior
to April 1, 2007. Thereafter, the Debentures will be subject to redemption at
any time at the option of the Issuer, in whole or in part, at 100% of the
principal amount plus accrued and unpaid interest to the applicable redemption
date (subject to the right of Holders on the relevant record date to receive
interest due on the relevant interest payment date).

     SECTION 3.08. No Sinking Fund. There shall be no sinking fund for the
payment of principal on the Debentures to the Debentureholders.

                                   ARTICLE IV

                                    COVENANTS

     SECTION 4.01. Payment of Debentures. The Issuer shall promptly pay the
principal of and interest on the Debentures on the dates and in the manner
provided in the Debentures and in this Indenture. Principal and interest shall
be considered paid on the date due if on such date the Trustee or the Paying
Agent (but only if other than the Issuer or a Wholly Owned Restricted
Subsidiary) holds by 10:00 a.m., New York City time, in

                                      -26-
<PAGE>
accordance with this Indenture available funds sufficient to pay all principal
and interest then due and the Trustee or the Paying Agent, as the case may be,
is not prohibited from paying such money to the Debentureholders on that date
pursuant to the terms of this Indenture.

     The Issuer shall pay interest on overdue principal at the rate specified
therefor in the Debentures, and it shall pay interest on overdue installments of
interest at the same rate to the extent lawful.

     SECTION 4.02. Reports. During any period in which the Issuer is subject to
the reporting requirements of Section 13 or 15(d) of the Exchange Act, to the
extent permitted by the Exchange Act, the Issuer will file with the SEC, and
provide, within 15 days after the Issuer is required to file the same with the
SEC, the Trustee and the Debenture holders with the annual reports and the
information, documents and other reports that are specified in Sections 13 and
15(d) of the Exchange Act. During any period in which the Issuer is not required
to file such reports, documents and information with the SEC, the Issuer will
provide the Trustee and Debenture holders annual reports containing financial
statements audited by our independent auditors. To the extent the requirements
of this Section 4.02 conflict with TIA Section 3.14(a), this Section 4.02 shall
control.

     SECTION 4.03. Dividend and Other Payment Restrictions Affecting Restricted
Subsidiaries. The Issuer shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to
exist or become effective any consensual encumbrance or restriction on the
ability of any Restricted Subsidiary to (i)(a) pay dividends or make any other
distributions to the Issuer or any of its Restricted Subsidiaries (1) on its
Capital Stock or (2) with respect to any other interest or participation in, or
measured by, its profits, or (b) pay any Debt owed to the Issuer or any of its
Restricted Subsidiaries, (ii) make loans or advances to the Issuer or any of its
Restricted Subsidiaries or (iii) transfer any of its properties or assets to the
Issuer or any of its Restricted Subsidiaries, except for such encumbrances or
restrictions existing or by reason of:

          (1) under the Senior Debt and any contracts in effect on the date
     hereof, including the Credit Facilities and other Existing Debt and the
     related documentation, as in effect on the date hereof;

          (2) this Indenture, the Debentures, the Debenture Guarantees and any
     other agreement entered into after the date hereof, provided that the
     encumbrances or restrictions in such agreements are not materially more
     restrictive than those contained in the foregoing agreements;

          (3) any agreement or other instrument of a Person acquired by the
     Issuer or any of its Restricted Subsidiaries as in effect at the time of
     such acquisition (but not

                                      -27-
<PAGE>
     created in connection with or in contemplation of such acquisition), which
     encumbrance or restriction is not applicable to any Person, or the
     properties or assets of any Person, other than the Person, or the property
     or assets of the Person, so acquired;

          (4) purchase money obligations (including Capital Lease Obligations)
     for property acquired in the ordinary course of business that impose
     restrictions of the nature described in clause (iii) above on the property
     so acquired;

          (5) in the case of clause (iii) above, any encumbrance or restriction
     (i) that restricts in a customary manner the subletting, assignment, or
     transfer of any property or asset that is subject to a lease, license or
     similar contract or (ii) contained in security agreements or mortgages
     securing Debt to the extent such encumbrance or restriction restricts the
     transfer of the property subject to such security agreements or mortgages;

          (6) in the case of clause (iii) above, any Lien on property or assets
     of the Issuer or any Restricted Subsidiary not otherwise prohibited by this
     Indenture;

          (7) any restriction under an agreement (including an option or right)
     to sell property or assets of, or Equity Interest in, the Issuer or any
     Restricted Subsidiary pending the closing of such sale, which sale is
     permitted under this Indenture;

          (8) restrictions on cash or other deposits or net worth imposed by
     leases or other agreements entered into in the ordinary course of business;

          (9) customary provisions in joint venture agreements and other similar
     agreements entered into in the ordinary course of business;

          (10) any encumbrances or restrictions created with respect to (i) Debt
     or Preferred Stock of Guarantors and (ii) Preferred Stock of Subsidiaries
     that are not Guarantors, provided that in the case of this clause (ii) the
     General Partner of the Issuer determines (as evidenced by a resolution of
     the Board of Directors of General Partner) in good faith at the time such
     encumbrances or restrictions are created that such encumbrances or
     restrictions would not reasonably be expected to impair the ability of the
     Issuer to make payments of interest and scheduled payments of principal on
     the Debentures in each case as and when due; or

          (11) any amendments, modifications, restatements, renewals, increases,
     supplements, refundings, replacements or refinancings of the contracts,
     instruments or obligations referred to in clauses (1) through (l0) above,
     provided that such amendments, modifications, restatements, renewals,
     increases, supplements, refundings, replacements or refinancings, taken as
     a whole, are, in the good faith

                                      -28-
<PAGE>
     judgment of the Issuer, not materially more restrictive with respect to
     such encumbrances or restrictions than those contained in the contracts,
     instruments or obligations prior to such amendment, modification,
     restatement, renewal, increase, supplement, refunding, replacement or
     refinancing.

     SECTION 4.04. Compliance Certificate. The Issuer shall deliver to the
Trustee within 120 days after the end of each fiscal year of the Issuer an
Officers' Certificate stating that in the course of the performance by the
signers of their duties as Officers of the General Partner they would normally
have knowledge of any Default and whether or not the signers know of any Default
that occurred during such period. If they do have such knowledge, the
certificate shall describe the Default, its status and what action the Issuer is
taking or proposes to take with respect thereto. The Issuer also shall comply
with Section 314(a)(4) of the TIA.

     The Issuer shall deliver to the Trustee, as soon as possible and in any
event within five days after the Issuer becomes aware of the occurrence of any
Event of Default or an event which, with notice or the lapse of time or both,
would constitute an Event of Default, an Officers' Certificate setting forth the
details of such Event of Default or Default and the action which the Issuer
proposes to take with respect thereto.

     SECTION 4.05. Limitation on Designations of Unrestricted Subsidiaries. The
General Partner of the Issuer may designate (a "Designation") any Restricted
Subsidiary (including any newly acquired or newly formed Subsidiary of the
Issuer) to be an Unrestricted Subsidiary unless such Subsidiary owns any Capital
Stock of, or owns or holds any Lien on any property of, the Issuer or any
Restricted Subsidiary, so long as no Default or Event of Default shall have
occurred and is continuing at the time of or after giving effect to such
Designation. Notwithstanding the foregoing, no Subsidiary shall be Designated as
an "Unrestricted Subsidiary" unless such Subsidiary:

          (1) has no Debt other than Non-Recourse Debt;

          (2) is not a Guarantor;

          (3) is not party to any agreement, contract, arrangement or
     understanding with the Issuer or any Restricted Subsidiary unless the terms
     of the agreement, contract, arrangement or understanding are no less
     favorable to the Issuer or the Restricted Subsidiary than those that might
     be obtained at the time from Persons who are not Affiliates; and

          (4) is a Person with respect to which neither the Issuer nor any
     Restricted Subsidiary has any direct or indirect obligation (a) to
     subscribe for additional Equity

                                      -29-
<PAGE>
     Interests or (b) to maintain or preserve the Person's financial condition
     or to cause the Person to achieve any specified levels of operating
     results.

     The General Partner of the Issuer may revoke any Designation of a
Subsidiary as an Unrestricted Subsidiary (a "Revocation"), provided that:

          (1) no Default shall have occurred and be continuing at the time of or
     after giving effect to such Revocation; and

          (2) all Liens and Debt of such Unrestricted Subsidiary outstanding
     immediately after such Revocation would, if incurred at such time, have
     been permitted to be incurred (and shall be deemed to have been incurred)
     for all purposes of this Indenture.

     Any such Designation or Revocation by the General Partner after the date
hereof shall be evidenced to the Trustee by promptly filing with the Trustee a
copy of the resolution of the Board of Directors of the General Partner giving
effect to such Designation or Revocation and an Officers' Certificate certifying
that such Designation or Revocation complied with the foregoing provisions.

     SECTION 4.06. Liens. The Issuer shall not, and shall not permit any of its
Restricted Subsidiaries to, create, incur, assume or otherwise cause or suffer
to exist or become effective any Lien of any kind securing Debt (or with respect
to Collateral, Liens of any kind) upon any of their property or assets, now
owned or hereafter acquired, other than Permitted Liens.

     SECTION 4.07. Additional Debenture Guarantees. All current and future
Subsidiaries of the Issuer, other than Foreign Subsidiaries, and Subsidiaries
that have been properly designated as Unrestricted Subsidiaries in accordance
with this Indenture for so long as they continue to constitute Unrestricted
Subsidiaries, will be Guarantors in accordance with the terms of this Indenture.

     SECTION 4.08. Business Activities. The Issuer shall not, and shall not
permit any Restricted Subsidiary to, engage in any business other than Permitted
Businesses, except to such extent as is not material to the Issuer and its
Restricted Subsidiaries taken as a whole.

     SECTION 4.09. Further Assurances. The Issuer shall, and shall cause each of
the Subsidiary Guarantors to do, execute, acknowledge, deliver, record,
re-record, file, re-file, register and re-register, as applicable, any and all
such further acts, deeds, security agreements, pledge agreements, mortgages,
assignments, estoppel certificates, financing statements and continuations
thereof, termination statements, and other instruments as may be required by the
Trustee from time to time in order to:

                                      -30-
<PAGE>
          (1) carry out more effectively the purposes of the Collateral
     Documents;

          (2) subject to the Liens created by any of the Collateral Documents,
     any of the properties, rights or interest required to be encumbered
     thereby;

          (3) perfect and maintain the validity, effectiveness and priority of
     any of the Collateral Documents and the Liens intended to be created
     thereby; and

          (4) better assure, grant, preserve, protect and confirm to the Trustee
     any of the rights granted now or hereafter intended by the parties thereto
     to be granted to the Trustee under any other instrument executed in
     connection therewith or granted to the Collateral Agent or Trustee, as
     applicable under the Collateral Documents or under any other instrument
     executed in connection therewith.

     SECTION 4.10. Limited Partnership Existence. Except as otherwise permitted
by Article V, the Issuer shall do or cause to be done all things necessary to
preserve and keep in full force and effect its existence as a limited
partnership and the corporate, partnership or other existence of each of its
Restricted Subsidiaries in accordance with the respective organizational
documents of each such Restricted Subsidiary and the rights (charter and
statutory) and material franchises of each of its Restricted Subsidiaries;
provided, however, that the Issuer shall not be required to preserve any such
right, franchise, limited partnership or corporate existence with respect to
each such Restricted Subsidiary if the General Partner of the Issuer shall
determine that the loss thereof would not, individually or in the aggregate,
have a material adverse effect on the business, financial condition or results
of operations of the Issuer and its Restricted Subsidiaries taken as a whole.

                                    ARTICLE V

                                SUCCESSOR ISSUER

     SECTION 5.01. Merger, Consolidation or Sale of All or Substantially All
Assets of the Issuer. The Issuer shall not consolidate or merge with or into
(whether or not the Issuer is the surviving entity), or sell, assign, transfer,
lease, convey or otherwise dispose of all or substantially all of its properties
or assets in one or more related transactions, to another Person unless:

               (i) the Issuer is the surviving entity or the Person formed by or
          surviving any such consolidation or merger (if other than the Issuer)
          or to which such sale, assignment, transfer, lease, conveyance or
          other disposition shall have been made is a limited partnership or
          other entity organized or existing under the laws of the United
          States, any state thereof or the District of Columbia;

                                      -31-
<PAGE>
               (ii) the Person formed by or surviving any such consolidation or
          merger (if other than the Issuer) or the Person to which such sale,
          assignment, transfer, lease, conveyance or other disposition shall
          have been made assumes all the obligations of the Issuer under the
          Debentures, this Indenture, and the Collateral Documents, pursuant to
          a supplemental indenture and other documents reasonably satisfactory
          to the Trustee; and

               (iii) immediately after such transaction no Default exists.

     Notwithstanding clause (iii) above, (a) any Restricted Subsidiary may
consolidate with, merge into or transfer all or part of its properties and
assets to the Issuer; (b) the Issuer may merge or consolidate with an Affiliate
organized solely for the purpose of reorganizing the Issuer in another
jurisdiction; and (c) the Merger may occur.

     For purposes of the foregoing, the transfer (by lease, assignment, sale or
otherwise, in a single transaction or series of related transactions) of all or
substantially all of the properties and assets of one or more Restricted
Subsidiaries of the Issuer, the Capital Stock of which constitutes all or
substantially all of the assets and properties of the Issuer (determined on a
consolidated basis for the Issuer and its Subsidiaries), shall be deemed to be
the transfer of all or substantially all of the properties and assets of the
Issuer.

     Upon any consolidation or merger in which the Issuer is not the continuing
entity, or any transfer of all or substantially all of the assets of the Issuer
in each case in accordance with the foregoing, the surviving entity or the
Person formed by or surviving any such consolidation or merger shall succeed to,
and be substituted for, and may exercise every right and power of, the Issuer
under the Debentures, this Indenture, and the Collateral Documents, with the
same effect as if such surviving entity or the Person formed by or surviving any
such merger or consolidation had been named as such.

     With respect to each transaction described above, the Issuer or the
relevant surviving entity, as applicable, will cause such amendments or other
instruments to be filed and recorded in such jurisdictions as may be required by
applicable law to preserve and protect the Lien of the Collateral Documents on
the Collateral owned by or transferred to such Person, together with such
financing statements as may be required to perfect any security interests in
such Collateral which may be perfected by the filing of a financing statement
under the Uniform Commercial Code of the relevant states.

     SECTION 5.02. Merger, Consolidation or Sale of All or Substantially All
Assets of a Guarantor. No Guarantor may consolidate with or merge with or into
(whether or not such Guarantor is the surviving Person) another Person (other
than the Issuer or another Guarantor) unless:

                                      -32-
<PAGE>
               (i) subject to the provisions of the following paragraph, the
          Person formed by or surviving any such consolidation or merger (if
          other than such Guarantor) is organized under the laws of any State of
          the United States of America or the District of Columbia and assumes
          all the obligations of such Guarantor under the Debenture Guarantee of
          such Guarantor, this Indenture and the Collateral Documents applicable
          to such Guarantor pursuant to a supplemental indenture reasonably
          satisfactory to the Trustee; and

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

     Notwithstanding the foregoing clause (ii) above, (a) any Restricted
Subsidiary may consolidate with, merge into or transfer all or part of its
properties and assets to any Guarantor, (b) any Guarantor may merge with an
Affiliate organized solely for the purpose of reorganizing such Guarantor in
another jurisdiction and (c) the Merger may occur.

     Upon any consolidation or merger in which a Guarantor is not the continuing
entity in accordance with the foregoing, the surviving entity or the Person
formed by or surviving any such consolidation or merger (if other than such
Guarantor) shall succeed to, and be substituted for, and may exercise every
right and power of, such Guarantor under its Debenture Guarantee, this
Indenture, and the Collateral Documents applicable to such Guarantor with the
same effect as if such surviving limited partnership or the Person formed by or
surviving any such consolidation or merger (if other than such Guarantor) had
been named as such.

WITH RESPECT TO EACH TRANSACTION DESCRIBED IN THE ABOVE PARAGRAPHS, ISSUER, SUCH
GUARANTOR OR THE RELEVANT SURVIVING ENTITY, AS APPLICABLE, WILL CAUSE SUCH
AMENDMENTS OR OTHER INSTRUMENTS TO BE FILED AND RECORDED IN SUCH JURISDICTIONS
AS MAY BE REQUIRED BY APPLICABLE LAW TO PRESERVE AND PROTECT THE LIEN OF THE
COLLATERAL DOCUMENTS ON THE COLLATERAL OWNED BY OR TRANSFERRED TO SUCH PERSON,
TOGETHER WITH SUCH FINANCING STATEMENTS AS MAY BE REQUIRED TO PERFECT ANY
SECURITY INTERESTS IN SUCH COLLATERAL WHICH MAY BE PERFECTED BY THE FILING OF A
FINANCING STATEMENT UNDER THE UNIFORM COMMERCIAL CODE OF THE RELEVANT STATES.

                                   ARTICLE VI

                              DEFAULTS AND REMEDIES

     SECTION 6.01. Events of Default and Remedies. (a) An "Event of Default"
occurs if:

          (1) default for 30 days in the payment when due of interest on the
     Debentures;

          (2) default in payment when due of the principal of or premium, if
     any, on the Debentures (including the failure to make a payment to purchase
     Debentures tendered pursuant to a redemption notice);

          (3) failure by the Issuer for 30 days after receipt of notice from the
     Trustee or the holders of at least 25% in principal amount of the then
     outstanding Debentures to comply with the provisions of 5.01 or 5.02;

          (4) failure by the Issuer for 60 days after receipt of notice from the
     Trustee or the holders of at least 25% in aggregate principal amount of the
     then outstanding Debentures specifying such failure to comply with any of
     its other agreements in this Indenture or the Debentures;

          (5) the failure by the Issuer or any Restricted Subsidiary that is a
     Significant Subsidiary to pay any Debt within any applicable grace period
     after final maturity or acceleration by the holders thereof because of a
     default if the total amount of all such Debt unpaid or accelerated at the
     time exceeds $2 million;

          (6) any judgment or decree for the payment of money in excess of $10
     million (net of any insurance or indemnity payments actually received in
     respect thereof prior to or within 90 days from the entry thereof, or to be
     received in respect thereof in the event any appeal thereof shall be
     unsuccessful) is entered against the Issuer or any Significant Subsidiary
     that is a Restricted Subsidiary and is not discharged, waived or stayed and
     either (A) an enforcement proceeding has been commenced by any creditor
     upon such judgment or decree or (B) there is a period of 90 days following
     the entry of such judgment or decree during which such judgment or decree
     is not discharged, waived or the execution thereof stayed;

          (7) any Debenture Guarantee shall be held in any judicial proceeding
     to be unenforceable or invalid or, except as permitted by this Indenture,
     shall cease for any reason to be in full force and effect or any Guarantor,
     or any Person acting on behalf

                                      -34-
<PAGE>
     of any Guarantor, shall deny or disaffirm its obligations under its
     Debenture Guarantee;

          (8) default by the Issuer or any Subsidiary Guarantor in the
     performance of the Collateral Documents which results in the
     unenforceablity, invalidity, imperfection or lack of requisite priority of
     the Trustee's or the Collateral Agent's Lien on Collateral with a fair
     market value in excess of $10 million, or the repudiation or disaffirmation
     by the Issuer or any Subsidiary Guarantor of its obligations under the
     Collateral Documents or the determination in a judicial proceeding that the
     Collateral Documents are unenforceable or invalid against the Issuer or any
     Subsidiary Guarantor for any reason;

          (9) an Event of Default (as defined in the Class A Indenture) has
     occurred and is continuing under the Class A Indenture.

          (10) the Issuer or any Restricted Subsidiary that is a 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 any
          substantial part of its property;

               (D) makes a general assignment for the benefit of its creditors;
          or takes any comparable action under any foreign laws relating to
          insolvency; or

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

               (A) is for relief against the Issuer or any Restricted Subsidiary
          that is a Significant Subsidiary in an involuntary case;

               (B) appoints a Custodian of the Issuer or any Restricted
          Subsidiary that is a Significant Subsidiary or for any substantial
          part of its property; or

               (C) orders the winding up or liquidation of the Issuer or any
          Restricted Subsidiary that is a Significant Subsidiary;

                                      -35-
<PAGE>
          or any similar relief is granted under any foreign laws and the order
          or decree relating thereto remains unstayed and in effect for 60 days.

     The foregoing shall constitute Events of Default whatever the reason for
any such Event of Default and whether it is voluntary or involuntary or is
effected by operation of law or pursuant to any judgment, decree or order of any
court or any order, rule or regulation of any administrative or governmental
body.

     The term "Bankruptcy Law" means Title 11, United States Code, or any
similar federal or state law for the relief of debtors. For purposes of this
Section, the term "Custodian" means any receiver, trustee, assignee, liquidator,
custodian or similar official under any Bankruptcy Law.

     A Default under clause (3) or (4) is not an Event of Default until the
Trustee or the Holders of at least 25% in aggregate principal amount of the
outstanding Debentures notify the Issuer in writing by registered or certified
mail, return receipt requested, of the Default and the Issuer does not cure such
Default within the time specified in clauses (3) and (4) after receipt of such
notice. Such notice must specify the Default, demand that it be remedied and
state that such notice is a "Notice of Default."

     SECTION 6.02. Acceleration. (a) If an Event of Default (other than an Event
of Default specified in Section 6.01(a)(10) or (11) with respect to the Issuer)
occurs and is continuing, the Trustee by notice to the Issuer in writing, or the
Holders of at least 25% in aggregate principal amount of the outstanding
Debentures by notice in writing to the Issuer, may declare the principal of and
accrued but unpaid interest on all the Debentures to be due and payable. Upon
such a declaration, such principal and interest shall be due and payable
immediately. Notwithstanding the foregoing, if an Event of Default specified in
Section 6.01(a)(10) or (11) with respect to the Issuer occurs, the principal of
and interest on all the Debentures shall ipso facto become and be immediately
due and payable without any declaration or other act on the part of the Trustee
or any Debentureholders.

     (b) At any time after a declaration of acceleration with respect to the
Debentures as described in Section 6.02(a), the Holders of a majority in
aggregate principal amount of the Debentures may rescind and cancel such
declaration and its consequences: (i) if the rescission would not conflict with
any judgment or decree; (ii) if all existing Events of Default have been cured
or waived except nonpayment of principal or interest that has become due solely
because of the acceleration; (iii) to the extent the payment of such interest is
lawful, interest on overdue installments of interest and overdue principal,
which has become due otherwise than by such declaration of acceleration, has
been paid; and (iv) if the Issuer has paid the Trustee its reasonable
compensation and reimbursed the Trustee for its expenses,

                                      -36-
<PAGE>
disbursements and advances. No such rescission shall affect any subsequent
Default or impair any right consequent thereto.

     SECTION 6.03. Other Remedies. If an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy to collect the payment
of principal of or interest on the Debentures or to enforce the performance of
any provision of the Debentures or this Indenture.

     The Trustee may maintain a proceeding even if it does not possess any of
the Debentures or does not produce any of them in the proceeding. A delay or
omission by the Trustee or any Debentureholder 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 6.04. Waiver of Past Defaults. The Holders of a majority in
aggregate principal amount of the Debentures then outstanding by written notice
to the Trustee may on behalf of the Holders of all of the Debentures waive any
existing Default or Event of Default and its consequences under this Indenture
except a continuing Default or Event of Default in the payment of interest on,
or the principal of or premium on, the Debentures. When a Default is waived, it
is deemed cured and ceases to exist and any Event of Default arising therefrom
shall be deemed to have been cured and waived for every purpose under this
Indenture, but no such waiver shall extend to any subsequent or other Default or
Event of Default or impair any consequent right.

     SECTION 6.05. Control by Majority. The Holders of a majority in aggregate
principal amount of the Debentures may direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee or of
exercising any trust or power conferred on the Trustee by this Indenture.
However, the Trustee may refuse to follow any direction that conflicts with law
or this Indenture or, subject to Section 7.01, that the Trustee determines is
unduly prejudicial to the rights of other Debentureholders or would involve the
Trustee in personal liability; provided, however, that the Trustee may take any
other action deemed proper by the Trustee that is not inconsistent with such
direction. Prior to taking any action hereunder, the Trustee shall be entitled
to indemnification satisfactory to it in its sole discretion against all losses
and expenses caused by taking or not taking such action.

     SECTION 6.06. Limitation on Suits. Except to enforce the right to receive
payment of principal, premium, if any, or interest when due, no Debentureholder
may pursue any remedy with respect to this Indenture or the Debentures unless:

                                      -37-
<PAGE>
          (1) such Holder has previously given the Trustee notice that an Event
     of Default is continuing;

          (2) Holders of at least 25% in aggregate principal amount of the
     outstanding Debentures have made a written request to the Trustee to pursue
     the remedy;

          (3) such Holders have offered the Trustee security or indemnity
     reasonably satisfactory to it against any loss, liability or expense;

          (4) the Trustee has not complied with request within 60 days after the
     receipt of the request and the offer of security or indemnity; and

          (5) the Holders of a majority in aggregate principal amount of the
     outstanding Debentures have not given the Trustee a direction inconsistent
     with such request within such 60-day period.

     A Debentureholder may not use this Indenture or the Collateral Documents to
prejudice the rights of another Debentureholder or to obtain a preference or
priority over another Debentureholder.

     SECTION 6.07. Rights of Holders To Receive Payment. Notwithstanding any
other provision of this Indenture, the right of any Holder to receive payment of
principal of and interest on the Debentures held by such Holder, on or after the
respective due dates expressed in the Debentures, or to bring suit for the
enforcement of any such payment on or after such respective dates, shall not be
impaired or affected without the consent of such Holder; provided that a Holder
shall not have the right to institute any such suit for the enforcement of
payment if and to the extent that the institution or prosecution thereof or the
entry of judgment therein would, under applicable law, result in the surrender,
impairment, waiver or loss of the Lien of this Indenture and the Collateral
Documents upon any of the Collateral.

     SECTION 6.08. Collection Suit by Trustee. If an Event of Default specified
in Section 6.01(a)(1) or (2) occurs and is continuing, the Trustee may recover
judgment in its own name and as trustee of an express trust against the Issuer
for the whole amount then due and owing (together with interest on any unpaid
interest to the extent lawful) and the amounts provided for in Section 7.07.

     SECTION 6.09. Trustee May File Proofs of Claim. The Trustee may file such
proofs of claim and other papers or documents as may be necessary or advisable
in order to have the claims of the Trustee and the Debentureholders allowed in
any judicial proceedings relative to the Issuer, any Subsidiary or any
Guarantor, their creditors or their property and, unless prohibited by law or
applicable regulations, may vote on behalf of the Holders in any

                                      -38-
<PAGE>
election of a trustee in bankruptcy or other Person performing similar
functions, and any Custodian in any such judicial proceeding is hereby
authorized by each Holder to make 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 it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and its counsel, and any other amounts due the Trustee under Section 7.07.

     SECTION 6.10. Priorities. If the Trustee collects any money or property
pursuant to this Article VI, it shall pay out the money or property in the
following order:

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

          SECOND: to Debentureholders for amounts due and unpaid on the
     Debentures for principal, interest and premium, if any, ratably, according
     to the amounts due and payable on the Debentures for principal, interest,
     and premium, if any, respectively; and

          THIRD: to the Issuer.

     The Trustee may fix a record date and payment date for any payment to
Debentureholders pursuant to this Section. At least 15 days before such record
date, the Trustee shall mail to each Debentureholder and the Issuer a notice
that states the record date, the payment date and amount to be paid.

     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 does not apply to a suit by
the Trustee, a suit by a Holder pursuant to Section 6.07 or a suit by Holders of
more than 10% in principal amount of the Debentures.

     SECTION 6.12. Waiver of Stay or Extension Laws. Neither the Issuer nor any
Guarantor (to the extent they may lawfully do so) shall at any time insist upon,
or plead, or in any manner whatsoever claim or take the benefit or advantage of,
any stay or extension law wherever enacted, now or at any time hereafter in
force, which may affect the covenants or the performance of this Indenture; and
the Issuer and each Guarantor (to the extent that they may lawfully do so)
hereby expressly waive all benefit or advantage of any such law, and shall not
hinder, delay or impede the execution of any power herein granted to the
Trustee,

                                      -39-
<PAGE>
but shall suffer and permit the execution of every such power as though no such
law had been enacted.

                                   ARTICLE VII

                                     TRUSTEE

     SECTION 7.01. Duties of Trustee. (a) If an Event of Default has occurred
and is continuing, the Trustee shall exercise 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 Person would exercise or use under the circumstances in the conduct of
such Person's own affairs.

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

          (1) the Trustee undertakes to perform such duties and only such duties
     as are specifically set forth in this Indenture and the Collateral
     Documents and no implied covenants or obligations shall be read into this
     Indenture or the Collateral Documents against the Trustee; and

          (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 and the
     Collateral Documents. However, 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 examine the certificates and
     opinions to determine whether or not they conform to the requirements of
     this Indenture or the Collateral Documents.

     (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 Section 7.01(b);

          (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; and

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

                                      -40-
<PAGE>
     (d) Every provision of this Indenture that in any way relates to the
Trustee is subject to paragraphs (a), (b) and (c) of this Section.

     (e) The Trustee shall not be liable for interest on any money received by
it except as the Trustee may agree in writing with the Issuer.

     (f) Money held in trust by the Trustee need not be segregated from other
funds except to the extent required by law.

     (g) No provision of this Indenture or the Collateral Documents shall
require the Trustee to expend or risk its own funds or otherwise incur any
financial liability in the performance of any of its duties hereunder or
thereunder or in the exercise of any of its rights or powers, if it shall have
reasonable grounds to believe that repayment of such funds or adequate indemnity
against such risk or liability is not reasonably assured to it.

     (h) Every provision of this Indenture relating to the conduct or affecting
the liability of or affording protection to the Trustee shall be subject to the
provisions of this Section and to the provisions of the TIA.

     SECTION 7.02. Rights of Trustee. Subject to Section 7.01:

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

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

          (c) The Trustee may act through agents and shall not be responsible
     for the misconduct or negligence of any agent appointed with due care.

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

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

                                      -41-
<PAGE>
          (f) The Trustee shall not be bound to make any investigation into the
     facts or matters stated in any resolution, certificate, statement,
     instrument, opinion, report, notice, request, consent, order, approval,
     bond, debenture, note or other paper or document unless requested in
     writing to do so by the Holders of not less than a majority in principal
     amount of the Debentures at the time outstanding, but the Trustee, in its
     discretion, may make such further inquiry or investigation into such facts
     or matters as it may see fit, and, if the Trustee shall determine to make
     such further inquiry or investigation, it shall be entitled to examine the
     books, records and premises of the Issuer, personally or by agent or
     attorney at the sole cost of the Issuer and shall incur no liability or
     additional liability of any kind by reason of such inquiry or
     investigation.

          (g) The Trustee shall not be required to give any note, bond or surety
     in respect of the execution of the trusts and powers under this Indenture.

          (h) The permissive rights of the Trustee to take any action enumerated
     in this Indenture shall not be construed as a duty to take such action.

          (i) The Trustee shall not be deemed to have notice of any Default or
     Event of Default unless a Trust Officer has actual knowledge thereof or
     unless a Trust Officer receives written notice thereof at its Corporate
     Trust Office specified in Section 14.02, from the Issuer or a Holder that
     such Default or Event of Default has occurred, and such notice references
     the Debentures and this Indenture.

          (j) The rights, privileges, protections, immunities and benefits given
     to the Trustee, including its right to be indemnified, are extended to, and
     shall be enforceable by, the Trustee in each of its capacities hereunder,
     and to each agent, custodian and other Person employed to act hereunder.

          (k) The Trustee may request that the Issuer deliver an Officers'
     Certificate 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 7.03. Individual Rights of Trustee. The Trustee in its individual
or any other capacity may become the owner or pledgee of Debentures and may
otherwise deal with the Issuer or its Affiliates with the same rights it would
have if it were not Trustee. Any Paying Agent, Registrar, co-registrar or
co-paying agent may do the same with like rights. However, the Trustee must
comply with Sections 7.10 and 7.11.

                                      -42-
<PAGE>
     SECTION 7.04. Trustee's Disclaimer. The Trustee shall not be responsible
for and makes no representation as to the validity or adequacy of this Indenture
or the Debentures, it shall not be accountable for the Issuer's use of the
proceeds from the Debentures, and it shall not be responsible for any statement
of the Issuer in this Indenture or in any document issued in connection with the
sale of the Debentures or in the Debentures other than the Trustee's certificate
of authentication.

     SECTION 7.05. Notice of Defaults. If a Default occurs and is continuing and
the Trustee has notice of such Default (as determined in accordance with Section
7.02(i) above), the Trustee shall mail to each Holder notice of the Default
within the earlier of 90 days after it occurs or 30 days after it is known to a
Trust Officer or written notice of it is received by the Trustee. Except in the
case of a Default in the payment of principal of, premium, if any, or interest
on any Debenture, the Trustee may withhold notice if and so long as a committee
of its trust officers in good faith determines that withholding notice is in the
interests of Debentureholders. If a Default occurs and is continuing and a
Senior Officer of the General Partner has actual knowledge of such Default, the
Issuer shall deliver to the Trustee written notice of such Default, which notice
shall include the status of such Default and any action being taken or proposed
to be taken by the Issuer with respect thereto. Notwithstanding anything to the
contrary expressed in this Indenture, the Trustee shall not be deemed to have
knowledge of any Default or Event of Default hereunder, except in the case of an
Event of Default under Section 6.01(a)(1) or (2) hereof (provided that the
Trustee is Paying Agent), unless and until a Trust Officer receives written
notice thereof at its Corporate Trust Office specified in Section 14.02, from
the Issuer or a Holder that such Default or Event of Default has occurred.

     SECTION 7.06. Reports by Trustee to Holders. The Trustee shall transmit to
the Holders such reports concerning the Trustee and its actions under this
Indenture as may be required pursuant to the TIA at the times and in the manner
provided pursuant thereto. To the extent that any such report is required by the
TIA with respect to any 12-month period, such report shall cover the 12-month
period ending December 31 and shall be transmitted by the next succeeding March
15.

     A copy of each report at the time of its mailing to Debentureholders shall
be filed with the SEC, if then required, and each stock exchange (if any) on
which the Debentures are listed. The Issuer agrees to notify promptly the
Trustee whenever the Debentures become listed on any stock exchange and of any
delisting thereof.

     SECTION 7.07. Compensation and Indemnity. The Issuer shall pay to the
Trustee from time to time such compensation as is agreed to in writing by the
Trustee and the Issuer for the Trustee's services hereunder and under the
Collateral Documents. The Trustee's compensation shall not be limited by any law
on compensation of a trustee of an express trust.

                                      -43-
<PAGE>
The Issuer shall reimburse the Trustee upon request for all reasonable
out-of-pocket disbursements, advances and expenses incurred or made by it,
including costs of collection, in addition to the compensation for its services.
Such expenses shall include the reasonable compensation and expenses,
disbursements and advances of the Trustee's agents, counsel, accountants and
experts. The Issuer and each Guarantor, jointly but not severally, shall
indemnify the Trustee and its officers, directors, shareholders, agents and
employees (each, an "Indemnified Party") for and hold each Indemnified Party
harmless against any and all loss, damage, claims, liability or expense
(including reasonable attorneys' fees and expenses) including taxes (other than
taxes based upon, measured by or determined by the income of the Trustee)
incurred by them without negligence or bad faith on their part arising out of or
in connection with the acceptance or administration of this Indenture or the
Debentures or any Collateral Document and the performance of their duties
hereunder or under the Collateral Documents, including the cost and expense of
enforcing this Indenture against the Issuer (including this Section 7.07), and
defending itself against any claim (whether asserted by a Holder or any other
person). The Trustee and its officers, directors, shareholders, agents and
employees in its capacity as Paying Agent, Registrar, Custodian and agent for
service of notice and demands shall have the full benefit of the foregoing
indemnity as well as all other benefits, rights and privileges accorded to the
Trustee in this Indenture when acting in such other capacity. The Trustee shall
notify the Issuer of any claim for which it may seek indemnity promptly upon
obtaining actual knowledge thereof; provided that any failure so to notify the
Issuer shall not relieve the Issuer or any Guarantor of its indemnity
obligations hereunder. The Issuer shall defend the claim and the Indemnified
Party shall provide reasonable cooperation at the Issuer's expense in the
defense. Such Indemnified Parties may have separate counsel and the Issuer shall
pay the fees and expenses of such counsel; provided that the Issuer shall not be
required to pay such fees and expenses if it assumes such Indemnified Parties'
defense and, in such Indemnified Parties' reasonable judgment, there is no
conflict of interest between the Issuer and such parties in connection with such
defense. The Issuer need not reimburse any expense or indemnify against any
loss, liability or expense incurred by an Indemnified Party through such party's
own willful misconduct, negligence or bad faith. The Issuer need not pay any
settlement made without its consent (which consent shall not be unreasonably
withheld).

     To secure the Issuer's payment obligations in this Section and all other
obligations to the Trustee pursuant to this Indenture, and the Collateral
Documents, including all fees, expenses, and rights to indemnification, the
Trustee shall have a lien on all money or property held or collected by the
Trustee other than money or property held in trust to pay principal of and
interest on particular Debentures. Such lien shall survive the satisfaction and
discharge of this Indenture and the termination of any Collateral Documents and
the resignation or removal of the Trustee. The Trustee's right to receive
payment of any amounts due under this Indenture and the termination of any
Collateral Documents shall not be subordinated to any

                                      -44-
<PAGE>
other Debt of the Issuer and the Debentures shall be subordinate to the
Trustee's rights to receive such payment.

     The Issuer's payment obligations pursuant to this Section shall survive the
satisfaction or discharge of this Indenture, any rejection or termination of
this Indenture under any Bankruptcy Law or the resignation or removal of the
Trustee. When the Trustee incurs expenses after the occurrence of a Default
specified in Section 6.01(a)(10) or (11) with respect to the Issuer, the
expenses are intended to constitute expenses of administration under the
Bankruptcy Law.

     SECTION 7.08. Replacement of Trustee. The Trustee may resign at any time by
so notifying the Issuer in writing. The Holders of a majority in principal
amount of the Debentures may remove the Trustee by so notifying the Trustee and
the Issuer in writing and may appoint a successor Trustee. The Issuer shall
remove the Trustee if:

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

          (2) the Trustee is adjudged bankrupt or 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, is removed by the Issuer or by the Holders of a
majority in principal amount of the Debentures and such Holders do not
reasonably promptly appoint a successor Trustee, or if a vacancy exists in the
office of Trustee for any reason (the Trustee in such event being referred to
herein as the retiring Trustee), the Issuer shall promptly appoint a successor
Trustee.

     A successor Trustee shall deliver a written acceptance of its appointment
to the retiring Trustee and to the Issuer. Thereupon the resignation or removal
of the retiring Trustee shall become effective, and the successor Trustee shall
have all the rights, powers and duties of the Trustee under this Indenture. The
successor Trustee shall mail a notice of its succession to Debentureholders. The
retiring Trustee shall promptly transfer all property held by it as Trustee to
the successor Trustee, subject to the lien provided for in Section 7.07.

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

                                      -45-
<PAGE>
     If the Trustee fails to comply with Section 7.10, any Debentureholder may
petition any court of competent jurisdiction for the removal of the Trustee and
the appointment of a successor Trustee.

     Notwithstanding the replacement of the Trustee pursuant to this Section,
the Issuer's obligations under Section 7.07 shall continue for the benefit of
the retiring Trustee.

     SECTION 7.09. Successor Trustee by Merger. If the Trustee consolidates
with, merges or converts into, or transfers all or substantially all its
corporate trust business or assets to, another corporation or banking
association, the resulting, surviving or transferee corporation without any
further act shall be the successor Trustee, provided, that such Person shall be
qualified and eligible under this Article VII.

     In case at the time such successor or successors by merger, conversion or
consolidation to the Trustee shall succeed to the trusts created by this
Indenture any of the Debentures shall have been authenticated but not delivered,
any such successor to the Trustee may adopt the certificate of authentication of
any predecessor trustee, and deliver such Debentures so authenticated; and in
case at that time any of the Debentures shall not have been authenticated, any
successor to the Trustee may authenticate such Debentures either in the name of
any predecessor hereunder or in the name of the successor to the Trustee.

     SECTION 7.10. Eligibility; Disqualification. The Trustee shall at all times
satisfy the requirements of TIA Section 310(a). The Trustee shall have a
combined capital and surplus of at least $50,000,000 as set forth in its most
recent published annual report of condition. The Trustee shall comply with TIA
Section 310(b); provided, however, that there shall be excluded from the
operation of TIA Section 310(b)(1) any indenture or indentures under which other
Securities or certificates of interest or participation in other Securities of
the Issuer are outstanding if the requirements for such exclusion set forth in
TIA Section 310(b)(1) are met.

     SECTION 7.11. Preferential Collection of Claims Against the Issuer. The
Trustee shall comply with TIA Section 311(a), excluding any creditor
relationship listed in TIA Section 311(b). A Trustee who has resigned or been
removed shall be subject to TIA Section 311(a) to the extent indicated therein.

                                  ARTICLE VIII

                       DISCHARGE OF INDENTURE; DEFEASANCE

     SECTION 8.01. Legal Defeasance and Covenant Defeasance. (a) The Issuer may,
at the option of its General Partner evidenced by a resolution of the General
Partner's Board of Directors set forth in an Officers' Certificate, at any time,
elect to have either

                                      -46-
<PAGE>
Section 8.01(b) or 8.01(c) hereof be applied to all outstanding Debentures upon
compliance with the conditions set forth below in this Article VIII.

     (b) Upon the Issuer's exercise under Section 8.01(a) hereof of the option
applicable to this Section 8.01(b), the Issuer and each Guarantor shall, subject
to the satisfaction of the conditions set forth in Section 8.02 hereof, be
deemed to have been discharged from their obligations with respect to all
outstanding Debentures and any Debenture Guarantee on the date the conditions
set forth below are satisfied (hereinafter, "Legal Defeasance"). For this
purpose, Legal Defeasance means that the Issuer and each Guarantor shall be
deemed to have paid and discharged the entire Debt represented by the
outstanding Debentures and any Debenture Guarantee, which Debentures and
Debenture Guarantee shall thereafter be deemed to be "outstanding" only for the
purposes of Section 8.03 hereof and the other Sections of this Indenture
referred to in (i) and (ii) below, and to have satisfied all their other
obligations under such Debentures and this Indenture (and the Trustee, on demand
of and at the expense of the Issuer, shall execute proper instruments
acknowledging the same), except for the following provisions which shall survive
until otherwise terminated or discharged hereunder: (i) the rights of Holders of
outstanding Debentures to receive solely from the trust fund described in
Article VIII hereof, as more fully set forth in such Article, payments in
respect of the principal of, premium, if any, and interest, if any, on such
Debentures when such payments are due, (ii) the Issuer's obligations with
respect to the Debentures under Sections 2.03, 2.04, 2.05, 2.06, 2.07, 2.09,
7.07 and 7.08, which shall survive until the Debentures have been paid in full
(thereafter, the Issuer's obligations in Section 7.07 shall survive), and (iii)
this Article VIII. Subject to compliance with this Article VIII, the Issuer may
exercise its option under this Section 8.01(b) notwithstanding the prior
exercise of its option under Section 8.01(c) hereof.

     (c) Upon the Issuer's exercise under Section 8.01(a) hereof of the option
applicable to this Section 8.01(c), the Issuer and each Guarantor shall, subject
to the satisfaction of the conditions set forth in Section 8.02 hereof, be
released from their obligations under Sections 4.02, 4.03, 4.04, 4.05, 4.06,
4.07 and 4.08 hereof with respect to the outstanding Debentures on and after the
date the conditions set forth below are satisfied (hereinafter, "Covenant
Defeasance"), and the Debentures shall thereafter be deemed not "outstanding"
for the purposes of any direction, waiver, consent or declaration of act of
Holders (and the consequences of any thereof) in connection with such Sections,
but shall continue to be deemed "outstanding" for all the other purposes
hereunder (it being understood that such Debentures and the related Debenture
Guarantee shall not be deemed outstanding for accounting purposes). For this
purpose, Covenant Defeasance means that, with respect of any term, condition or
limitation set forth in any such Section, whether directly or indirectly, by
reason of any reference elsewhere herein to any such Section or by reason of any
reference in any such Section to any other provision herein or in any other
document and such omission to comply shall not constitute a Default or an Event
of Default under Section 6.01 hereof, but,

                                      -47-
<PAGE>
except as specified above, the remainder of this Indenture and such Debentures
shall be unaffected thereby. In addition, upon the Issuer's exercise under
Section 8.01(a) hereof of the option applicable to this Section 8.01(c) hereof,
subject to the satisfaction of the conditions set forth in Section 8.02,
Sections 6.01(3), 6.01(4) (with respect to compliance with Sections 4.02, 4.03,
4.04, 4.05, 4.06, 4.07 and 4.08), 6.01(5), 6.01(6), 6.01(7) or 6.01(8)) shall
not constitute Events of Default.

     SECTION 8.02. Conditions to Legal or Covenant Defeasance. The following
shall be the conditions to the application of either Section 8.01(b) or 8.01(c)
hereof to the outstanding Debentures:

     In order to exercise either Legal Defeasance or Covenant Defeasance:

          (a) the Issuer must irrevocably deposit with the Trustee, in trust,
     for the benefit of the Holders, cash in United States dollars, Government
     Notes, or a combination thereof, in such amounts as will be sufficient
     (without reinvestment), in the opinion of a firm of independent public
     accountants reasonably acceptable to the Trustee, to pay the principal of,
     premium, if any, and interest on the outstanding Debentures on the Stated
     Maturity;

          (b) in the case of an election under Section 8.01(b) hereof, the
     Issuer shall have delivered to the Trustee an Opinion of Counsel in the
     United States reasonably acceptable to the Trustee confirming that (A) the
     Issuer has received from, or there has been published by, the Internal
     Revenue Service a ruling or (B) since the date hereof, there has been a
     change in the applicable federal income tax law, in either case to the
     effect that, and based thereon such Opinion of Counsel shall confirm that,
     subject to customary assumptions and exclusions, the Holders of the
     outstanding Debentures will not recognize income, gain or loss for federal
     income tax purposes as a result of such Legal Defeasance and will be
     subject to federal income tax on the same amounts, in the same manner and
     at the same times as would have been the case if such Legal Defeasance had
     not occurred;

          (c) in the case of an election under Section 8.01(c) hereof, the
     Issuer shall have delivered to the Trustee an Opinion of Counsel in the
     United States, reasonably acceptable to the Trustee confirming that,
     subject to customary assumptions and exclusions, the Holders of the
     outstanding Debentures will not recognize income, gain or loss for federal
     income tax purposes as a result of such Covenant Defeasance and will be
     subject to federal income tax on the same amounts, in the same manner and
     at the same times as would have been the case if such Covenant Defeasance
     had not occurred;

                                      -48-
<PAGE>
          (d) no Default or Event of Default shall have occurred and be
     continuing on the date of such deposit (other than a Default or Event of
     Default resulting from the borrowing of funds to be applied to such deposit
     and the grant of any Lien securing such borrowing);

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

          (f) the Issuer shall have delivered to the Trustee an Opinion of
     Counsel, subject to customary assumptions and exclusions, to the effect
     that after the 91st day following the deposit pursuant to Section 8.02(a),
     the trust funds will not be part of any "estate" formed by the bankruptcy
     or reorganization of the Issuer or subject to the "automatic stay" under
     the Bankruptcy Law, or in the case of a Covenant Defeasance, will be
     subject to a first priority Lien in favor of the Trustee for the benefit of
     the Holders;

          (g) the Issuer shall have delivered to the Trustee an Officers'
     Certificate stating that the deposit was not made by the Issuer with the
     intent of preferring the Holders over any other creditors of the Issuer or
     the Guarantors, as applicable, or with the intent of defeating, hindering,
     delaying or defrauding any other creditors of the Issuer or the Guarantors,
     as applicable, or others; and

          (h) the Issuer shall have delivered to the Trustee an Officers'
     Certificate and an Opinion of Counsel (which Opinion of Counsel may be
     subject to customary assumptions and exclusions), each stating that all
     conditions precedent relating to the Legal Defeasance or the Covenant
     Defeasance have been complied with.

     SECTION 8.03. Deposited Money and Government Securities To Be Held in
Trust; Other Miscellaneous Provisions. Subject to Section 8.04 hereof, all money
and Government Notes (including the proceeds thereof) deposited with the Trustee
(or other qualifying trustee, collectively for purposes of this Section 8.03,
the "Trustee") pursuant to Section 8.02 hereof in respect of the outstanding
Debentures shall be held in trust and applied by the Trustee, in accordance with
the provisions of such Debentures and this Indenture, to the payment, either
directly or through any Paying Agent (including the Issuer acting as Paying
Agent) as the Trustee may determine, to the Holders of such Debentures of all
sums due and to become due thereon in respect of principal, premium, if any, and
interest, but such money need not be segregated from other funds except to the
extent required by law.

                                      -49-
<PAGE>
     Anything in this Article VIII to the contrary notwithstanding, the Trustee
shall deliver or pay to the Issuer from time to time upon the request of the
Issuer any money or Government Notes held by it as provided in Section 8.02
hereof which, in the opinion of a firm of independent public accountants
reasonably acceptable to the Trustee expressed in a written certification
thereof delivered to the Trustee (which may be the opinion delivered under
Section 8.02(a) hereof), are in excess of the amount thereof that would then be
required to be deposited to effect an equivalent Legal Defeasance or Covenant
Defeasance.

     SECTION 8.04. Repayment to the Issuer. Any money deposited with the Trustee
or any Paying Agent, or then held by the Issuer, in trust for the payment of the
principal of, premium, if any, or interest on any Debenture and remaining
unclaimed for two years after such principal, premium, if any, or interest has
become due and payable shall be paid to the Issuer on its request or (if then
held by the Issuer) shall be discharged from such trust; and the Holder of such
Debenture shall thereafter, as an unsecured general creditor, look only to the
Issuer for payment thereof, and all liability of the Trustee or such Paying
Agent with respect to such trust money, and all liability of the Issuer as
trustee thereof, shall thereupon cease; provided, however, that the Trustee or
such Paying Agent, before being required to make any such repayment, may at the
expense of the Issuer, cause to be published once, in the New York Times
(national edition) and the Wall Street Journal (national edition), 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 notification or
publication, any unclaimed balance of such money then remaining will be repaid
to the Issuer.

     SECTION 8.05. Reinstatement. If the Trustee or Paying Agent is unable to
apply any United States dollars or Government Notes in accordance with this
Article VIII by reason of any order or judgment of any court or governmental
authority enjoining, restraining or otherwise prohibiting such application, then
the Issuer's obligations under this Indenture and the Debentures shall be
revived and reinstated as though no deposit had occurred pursuant to this
Article VIII until such time as the Trustee or Paying Agent is permitted to
apply all such money in accordance with this Article VIII; provided, however,
that, if the Issuer or any Guarantor makes any payment of principal of, premium,
if any, or interest on any Debenture following the reinstatement of its
obligations, the Issuer or any Guarantor, as the case may be, shall be
subrogated to the rights of the Holders of such Debentures to receive such
payment from the money held by the Trustee or Paying Agent.

     SECTION 8.06. Satisfaction and Discharge of Indenture. Upon the request of
the Issuer, this Indenture will cease to be of further effect (except as to
surviving rights of registration of transfer or exchange of the Debentures, as
expressly provided for herein or pursuant hereto), the Issuer and the Guarantors
will be discharged from their obligations under the Debentures and the Debenture
Guarantees, and the Trustee, at the expense of the

                                      -50-
<PAGE>
Issuer, will execute proper instruments acknowledging satisfaction and discharge
of this Indenture, the Debenture Guarantees and the Debentures when:

          (a) either (i) all the Debentures theretofore authenticated and
     delivered (other than mutilated, destroyed, lost or stolen Debentures that
     have been replaced or paid and Debentures that have been subject to
     defeasance under this Article VIII) have been delivered to the Trustee for
     cancellation or (ii) all Debentures not theretofore delivered to the
     Trustee for cancellation (A) have become due and payable, or (B) will
     become due and payable at maturity within one year, and the Issuer, in the
     case of (A) or (B) above, has irrevocably deposited or caused to be
     deposited with the Trustee funds in trust for such purpose in an amount
     sufficient to pay and discharge the entire Debt on such Debentures not
     theretofore delivered to the Trustee for cancellation, for principal (and
     premium, if any, on) and interest on the Debentures to the date of such
     deposit (in the case of Debentures that have become due and payable) or to
     the Stated Maturity;

          (b) the Issuer has paid or caused to be paid all sums payable under
     this Indenture by the Issuer; and

          (c) the Issuer has delivered to the Trustee an Officers' Certificate
     and an Opinion of Counsel, each stating that all conditions precedent
     provided in this Indenture relating to the satisfaction and discharge of
     this Indenture, the Debenture Guarantees, the security agreements relating
     thereto and the Debentures have been complied with.

     Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Issuer to the Trustee under Section 7.07 and, if money shall
have been deposited with the Trustee pursuant to clause (a)(ii) of this Section,
the obligations of the Trustee under Section 8.03 and Section 2.04 shall
survive.

                                   ARTICLE IX

                                   AMENDMENTS

     SECTION 9.01. Without Consent of Holders. The Issuer, the Guarantors and
the Trustee may amend or supplement this Indenture, the Debentures, the
Debenture Guarantees, or the Collateral Documents without notice to or consent
of any Debentureholder:

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

          (2) to provide for uncertificated Debentures in addition to or in
     place of certificated Debentures (provided that the uncertificated
     Debentures are issued in

                                      -51-
<PAGE>
     registered form for purposes of Section 163(f) of the Code, or in a manner
     such that the uncertificated Debentures are described in Section
     163(f)(2)(B) of the Code);

          (3) to provide for the assumption of the Issuer's or any Guarantor's
     obligations to Holders of Debentures in the case of a merger, consolidation
     or sale of assets;

          (4) to release any Debenture Guarantee or any Collateral or to release
     or subordinate the Lien on any Collateral on account of Permitted Liens
     permitted to be granted to third parties, or amend, restate and/or assign
     the Collateral Documents in connection with a refinancing of Senior Debt,
     in each case in accordance with the provisions of this Indenture and the
     Collateral Documents;

          (5) to provide for additional Guarantors or co-obligors;

          (6) to add Collateral;

          (7) to make any change that would provide any additional rights or
     benefits to the Holders of Debentures or that, as determined by the General
     Partner of the Issuer in good faith, does not materially adversely affect
     the legal rights of any such Holder under this Indenture, the Debentures or
     the Debenture Guarantees or the Collateral Documents; or

          (8) to the extent qualified, to comply with requirements of the SEC in
     order to effect or maintain the qualification of this Indenture under the
     TIA.

     After an amendment under this Section becomes effective, the Issuer shall
mail to Debentureholders a notice briefly describing such amendment. The failure
to give such notice to all Debentureholders, or any defect therein, shall not
impair or affect the validity of an amendment under this Section.

     SECTION 9.02. With Consent of Holders. The Issuer, the Guarantors and the
Trustee may amend or supplement this Indenture, the Debentures, the Debenture
Guarantees or the Collateral Documents without notice to any Debentureholder but
with the written consent of the Holders of at least a majority in principal
amount of the Debentures then outstanding (including consents obtained in
connection with a purchase of, or tender offer or exchange offer for,
Debentures), and any existing default or compliance with any provisions of this
Indenture, the Debentures, the Debenture Guarantees or the Collateral Documents
may be waived with the consent of the Holders of a majority in principal amount
of the then outstanding Debentures (including consents obtained in connection
with a tender offer or exchange offer for Debentures). Notwithstanding the
foregoing, without the consent of each

                                      -52-
<PAGE>
Holder affected, an amendment or waiver may not (with respect to any Debentures
held by a non-consenting Holder):

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

          (ii) reduce the principal of or change the fixed maturity of any
     Debenture;

          (iii) reduce the rate of or change the time for payment of interest on
     any Debenture;

          (iv) waive a Default in the payment of principal of or premium, if
     any, or interest on the Debentures (except a rescission of acceleration of
     the Debentures by the Holders of at least a majority in aggregate principal
     amount of the Debentures then outstanding and a waiver of the payment
     default that resulted from such acceleration);

          (v) make any Debenture payable in money other than that stated in the
     Debentures;

          (vi) impair the rights of Holders of Debentures to receive payments of
     principal of or premium, if any, or interest on the Debentures;

          (vii) make any change in the foregoing amendment or waiver provisions;

          (viii) subordinate the Debentures or any Debenture Guarantee to any
     other Debt; or

          (ix) except as permitted by this Indenture, release any Debenture
     Guarantee or substantially all of the Collateral.

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

     After an amendment under this Section becomes effective, the Issuer shall
mail to Debentureholders a notice briefly describing such amendment. The failure
to give such notice to all Debentureholders, or any defect therein, shall not
impair or affect the validity of an amendment under this Section.

     SECTION 9.03. Compliance with Trust Indenture Act. Every amendment to this
Indenture or the Debentures shall comply with the TIA as then in effect, either
as required under the TIA at the time or, if not required, to the extent set
forth in such amendment.

     SECTION 9.04. Revocation and Effect of Consents and Waivers. A consent to
an amendment or a waiver by a Holder of a Debenture shall bind the Holder and
every subsequent Holder of that Debenture or portion of the Debenture that
evidences the same debt as the consenting Holder's Debenture, even if notation
of the consent or waiver is not made on the Debenture. However, any such Holder
or subsequent Holder may revoke the consent or waiver as to such Holder's
Debenture or portion of the Debenture if the Trustee receives written notice of
revocation before the date the amendment or waiver becomes effective. After an
amendment or waiver becomes effective, it shall bind every Debentureholder.
Except if otherwise specified in such amendment or waiver, an amendment or
waiver becomes effective once the requisite number of consents are received by
the Issuer or the Trustee.

     The Issuer may, but shall not be obligated to, fix a record date for the
purpose of determining the Debentureholders entitled to give their consent or
take any other action described above or required or permitted to be taken
pursuant to this Indenture. If a record date is fixed, then notwithstanding the
immediately preceding paragraph, those Persons who were Debentureholders at such
record date (or their duly designated proxies), and only those Persons, shall be
entitled to give such consent or to revoke any consent previously given or to
take any such action, whether or not such Persons continue to be Holders after
such record date.

     SECTION 9.05. Notation on or Exchange of Debentures. If an amendment
changes the terms of a Debenture, the Trustee may require the Holder of the
Debenture to deliver it to the Trustee. The Trustee may place an appropriate
notation on the Debenture regarding the changed terms and return it to the
Holder. Alternatively, if the Issuer or the Trustee so determines, the Issuer in
exchange for the Debenture shall issue and the Trustee shall authenticate a new
Debenture that reflects the changed terms. Failure to make the appropriate
notation or to issue a new Debenture shall not affect the validity of such
amendment.

     SECTION 9.06. Trustee To Sign Amendments. The Trustee shall sign any
amendment authorized pursuant to this Article IX if the amendment 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 such amendment the
Trustee shall be entitled to receive indemnity reasonably satisfactory to it and
to receive, and (subject to Section 7.01) shall be fully protected in relying
upon, an Officers' Certificate and an Opinion of Counsel stating that such
amendment is authorized or permitted by this Indenture that such amendment is
the legal, valid and binding obligation of the Issuer and the Guarantors
enforceable against them in accordance with its terms, subject to customary
exceptions, and complies with the provisions hereof (including Section 9.03).

                                      -54-

     SECTION 9.07. Payment for Consent. Neither the Issuer nor any Affiliate of
the Issuer shall, directly or indirectly, pay or cause to be paid any
consideration, whether by way of interest, fee or otherwise, to any Holder for
or as an inducement to any consent, waiver or amendment of any of the terms or
provisions of this Indenture or the Debentures unless such consideration is
offered to be paid to all Holders that so consent, waive or agree to amend in
the time frame set forth in solicitation documents relating to such consent,
waiver or agreement.

                                    ARTICLE X

                              COLLATERAL DOCUMENTS

     SECTION 10.01. Collateral Documents; Additional Collateral.

     (a) Collateral Documents. In order to secure the due and punctual payment
of the Debentures, and the other amounts payable to the Trustee hereunder, the
Issuer, the Guarantors and the Trustee or the Collateral Agent, as the case may
be, shall on the date hereof enter into the Collateral Documents to create the
Security Interests and for related matters, and subsequent to the date hereof
shall enter into any such Collateral Documents as may be necessary or
appropriate to effect the provision of this Indenture or to set forth the
respective priorities between holders of Senior Debt and holders of Debentures.
Any Guarantor shall, upon becoming a Guarantor, become a party to each
applicable Collateral Document as shall be necessary or appropriate to grant and
create a valid Lien on all Collateral of such Guarantor, in each case, subject
to no Liens other than Permitted Liens. The Liens granted by Issuer and
Guarantors hereunder pursuant to the Collateral Documents shall rank junior to
the Liens granted by Issuer and Guarantors in respect of the Class A Debentures,
and the Collateral Agent shall act as a common collateral agent with respect to
the Liens granted to secure the Obligations under the Debentures and under the
Class A Debentures in accordance with the Collateral Documents.

     The Collateral Agent may also, but is not required to, act as a common
collateral agent with respect to any Liens granted pursuant to other Senior
Debt. If the holders or potential holders of Senior Debt require an
intercreditor or similar agreement setting forth the respective priorities of
Liens with respect to the Collateral, and the Trustee is unwilling to serve as
such common collateral agent or the holders of such Senior Debt require a
different collateral agent, the Issuer may appoint a replacement Collateral
Agent reasonably acceptable to the holders of Senior Debt in accordance with the
terms of the applicable Collateral Documents.

     (b) Additional Collateral. Promptly upon the acquisition or receipt by the
Issuer or any Guarantor of After-Acquired Property:

                                      -55-
<PAGE>
          (i) the Issuer or the applicable Guarantor, as the case may be, and
     the Collateral Agent will, if necessary, (A) enter into such amendments or
     supplements to the Collateral Documents or such additional Collateral
     Documents (in each case in registrable or recordable form if requested by
     the Trustee), and cause such amendments and supplements to be filed and
     recorded in all such governmental offices as shall be necessary in order to
     grant and create a valid and perfected Lien on and Security Interest in
     such After-Acquired Property in favor of the Collateral Agent (subject to
     no Liens except Permitted Liens) and (B) cause appropriate financing
     statements to be filed in such governmental offices as shall be reasonably
     necessary in order to perfect any security interest in such After-Acquired
     Property as to which a security interest may, under the UCC of the
     applicable jurisdiction, be perfected by the filing of a financing
     statement;

          (ii) the Issuer or the applicable Guarantor, as the case may be, shall
     also deliver to the Trustee the following:

               (A) an Opinion of Counsel either (a) substantially to the effect
          that, in the opinion of such counsel, the applicable Collateral
          Documents, financing statements and all other instruments of further
          assurance or assignment have been properly recorded and filed so as to
          make effective and perfect the Security Interests in such
          After-Acquired Property and reciting the details of such action or (b)
          to the effect that, in the opinion of such counsel, no such action is
          necessary to perfect the Security Interests in such After-Acquired
          Property; and

               (B) evidence of payment to be made by the Issuer or the
          applicable Guarantor of all filing fees, recording and registration
          charges, transfer taxes and other costs and expenses including
          reasonable legal fees and disbursements of counsel for the Trustee
          (and any local counsel) that may be incurred to validly and
          effectively subject such property to the Lien of the Collateral
          Documents and to perfect such Lien.

          (iii) in connection with the deliveries made pursuant to clauses (i)
     and (ii) of this Section 10.01(b), the Issuer or the applicable Guarantor
     shall deliver to the Trustee an Opinion of Counsel and an Officers'
     Certificate to the effect that the documents that have been or are
     therewith delivered to the Trustee pursuant to this Section 10.01(b)
     (including any amendments, supplements or other Collateral Documents
     referred to in clause (i) above) conform in all material respects to the
     requirements of this Indenture.

                                      -56-
<PAGE>
     (c) Each Holder, by accepting a Debenture, agrees to all of the terms and
provisions of the Collateral Documents, as the same may be amended from time to
time pursuant to the provisions of the Collateral Documents and this Indenture.

     SECTION 10.02. Recording, Etc. (a) The Issuer and each other Guarantor
shall take or cause to be taken all action required or desirable to maintain,
perfect, preserve and protect the Security Interests in the Collateral granted
by the Collateral Documents, to the extent required thereby, including, but not
limited to, causing all financing statements, any Collateral Documents, other
instruments of further assurance, including, without limitation, continuation
statements related to After-Acquired Property to be promptly recorded,
registered and filed, and at all times to be kept recorded, registered and
filed, and will execute and file such financing statements and cause to be
issued and filed such continuation statements, all in such manner and in such
places as may be required by law fully to preserve and protect the rights of the
Holders and the Trustee under this Indenture and the Collateral Documents to all
property comprising the Collateral.

     The Issuer shall from time to time promptly pay and discharge all financing
and continuation statement recording and/or filing fees, charges and taxes
relating to this Indenture and the Collateral Documents, any amendments thereto
and any other instruments of further assurance.

     (b) The Issuer shall furnish or cause to be furnished to the Trustee:

          (i) on the date hereof, Opinion(s) of Counsel either substantially to
     the effect that, in the opinion of such counsel, this Indenture, each
     Collateral Document and all other instruments of further assurance or
     assignment have been properly filed to the extent necessary to perfect or
     create the Security Interests created by each such Collateral Document, and
     reciting the details of such action, and stating that as to the Security
     Interests created pursuant to each such Collateral Document, such
     recordings, registrations and filings are the only recordings,
     registrations and filings necessary to give notice thereof; and

          (ii) within 30 days after April 30 in each year beginning with April
     30, 2005, an Opinion of Counsel, dated as of such date, either to the
     effect that, in the opinion of such counsel, such action has been taken
     with respect to the recordings, registrations, filings, re-recordings,
     re-registrations and refilings of all instruments of further assurance as
     is necessary to maintain the validity, enforceability and perfection of the
     Security Interests of each of the Collateral Documents, and reciting with
     respect to such Security Interests the details of such action (or to the
     extent that further action is required to be taken within the next twelve
     months, details of such further action) or referencing prior Opinions of
     Counsel in which such details are given.

                                      -57-
<PAGE>
     SECTION 10.03. Possession, Use and Release of Collateral. The Issuer and
Guarantors shall have the right to obtain a release of items of Collateral (the
"Released Interests") which the Issuer or the applicable Guarantor proposes to
Transfer and the Trustee shall furnish to the Collateral Agent authorization to
release the Released Interests from the Lien of the applicable Collateral
Documents and reconvey the Released Interests to the Issuer or the appropriate
Guarantor, upon compliance with the condition that the Issuer or the appropriate
Guarantor deliver to the Trustee the following:

     (a) Release Notice. A notice (each, a "Release Notice") from the Issuer or
the appropriate Guarantor requesting the release of the Released Interest (i)
describing the proposed Released Interest, (ii) specifying the fair market value
of such Released Interest on a date within 60 days of such notice (the
"Valuation Date"), (iii) specifying that the fair market value of the Released
Interest that is the subject of the Release Notice, plus all Released Interests
during the prior 12 months, does not exceed $500,000, and (iv) stating that the
release of such Released Interest will not interfere with the Trustee's ability
to realize the value of the remaining Collateral and will not impair the
maintenance and operation of the remaining Collateral;

     (b) Officers' Certificate. An Officers' Certificate of the Issuer or the
appropriate Guarantor stating that (i) such transfer does not include the sale
of assets other than the Released Interest, (ii) there is no Default in effect
or continuing on the date thereof, the Valuation Date or the date of such
transfer, and (iii) all conditions precedent in this Indenture and in the
Collateral Documents relating to the release in question have been complied
with; and

     (c) Other Documents. All documentation required by the TIA, if any, prior
to the release of Collateral by the Trustee.

     In connection with any release, the Issuer shall (i) execute, deliver and
record or file and obtain such instruments as the Trustee may reasonably
require, including, without limitation, amendments to the Collateral Documents,
and (ii) deliver to the Trustee such evidence of the satisfaction of the
applicable provisions of this Indenture and the Collateral Documents as the
Trustee may reasonably require.

     In case an Event of Default shall have occurred and be continuing, the
Issuer and the Guarantors, while in possession of the Collateral, may do any of
the things enumerated in this Section 10.03 only if the Trustee, in its
discretion, or the Holders of a majority of the principal amount of the
Debentures outstanding, by appropriate action of such Holders, shall consent to
such action, in which event any certificate filed under this Section 10.03 shall
omit the statement to the effect that no Event of Default has occurred and is
continuing. This

                                      -58-
<PAGE>
paragraph shall not apply, however, during the continuance of an Event of
Default of the type specified in Section 6.01(1) or (2).

     Any releases of Collateral made in strict compliance with the provisions of
this Section 10.03 shall be deemed not to impair the Security Interests created
by the Collateral Documents in favor of the Collateral Agent, in contravention
of the provisions of this Indenture.

     SECTION 10.04. Eminent Domain and Other Governmental Takings. Should any of
the Collateral be subject to a Taking, the Trustee shall release the property so
taken or purchased, but only upon receipt by the Trustee of the following:

          (a) an Officers' Certificate of the General Partner stating that such
     property has been Taken and the amount of the award or payment therefor,
     that all conditions precedent herein provided for relating to such release
     have been complied with; and

          (b) an Opinion of Counsel substantially to the effect:

               (1) that such property has been Taken by eminent domain, or has
          been sold pursuant to the exercise of a right vested in a governmental
          authority to purchase, or to designate a purchaser or order a sale of,
          such property;

               (2) in the case of any Taking by eminent domain, that the award
          for the property so taken has become final or that the General Partner
          or the applicable Guarantor has determined that an appeal from such
          award is not advisable in the interests of the Issuer or any other
          Guarantor, as applicable, or the Holders of the Debentures;

               (3) in the case of any such sale, that the payment with respect
          to the property so sold is not less than the amount to which the
          Issuer or the applicable Guarantor is legally entitled under the terms
          of such right to purchase or designate a purchaser, or under the order
          or orders directing such sale, as the case may be; and

               (4) that the instrument or the instruments and the award or
          payment of such Taking which have been or are therewith delivered to
          and deposited with the Trustee conform to the requirements of this
          Indenture and the applicable Collateral Document and that, upon the
          basis of such application, the Trustee is permitted by the terms
          hereof and of the applicable Collateral Document to authorize the
          Collateral Agent to execute and deliver the release requested, and
          that all conditions precedent herein and in the applicable

                                      -59-
<PAGE>
          Collateral Document provided for relating to such release have been
          complied with.

     In any proceedings for the Taking of any part of the Real Estate
Collateral, the Trustee may be represented by counsel who may be counsel for the
Issuer.

     SECTION 10.05. Trust Indenture Act Requirements. The release of any
Collateral from the Lien of any of the Collateral Documents or the release of,
in whole or in part, the Liens created by any of the Collateral Documents will
not be deemed to impair the Security Interests in contravention of the
provisions hereof if and to the extent the Collateral or Liens are released
pursuant to the applicable Collateral Documents and pursuant to the terms
hereof. The Trustee and each of the Holders of the Debentures acknowledge that a
release of Collateral or Liens strictly in accordance with the terms of the
Collateral Documents and the terms hereof will not be deemed for any purpose to
be an impairment of the Security Interests in contravention of the terms of this
Indenture. To the extent applicable, without limitation, the Issuer, Guarantors
and each other obligor on the Debentures shall cause TIA Section 314(d) relating
to the release of property or Debentures from the Liens hereof and of the
Collateral Documents to be complied with. Any certificate or opinion required by
TIA Section 314(d) may be made by an Officer of the Issuer or the appropriate
Guarantor, except in cases in which TIA Section 314(d) requires that such
certificate or opinion be made by an independent Person.

     SECTION 10.06. Suits to Protect the Collateral. Subject to the provisions
of the Collateral Documents, the Trustee shall have power to institute and to
maintain such suits and proceedings as it may deem expedient to prevent any
impairment of the Collateral by any acts which may be unlawful or in violation
of any of the Collateral 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 Trustee and the Holders in the Collateral
(including power to institute and maintain 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
or the Trustee).

     SECTION 10.07. Purchaser Protected. In no event shall any purchaser in good
faith of any property purported to be released hereunder be bound to ascertain
the authority of the Trustee or the Collateral Agent, as applicable, 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
by

                                      -60-
<PAGE>
this Article X to be sold be under obligation to ascertain or inquire into the
authority of the Issuer or any Guarantor, as applicable, to make any such sale
or other transfer.

     SECTION 10.08. 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 the Issuer or any
Guarantor, 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 the Issuer or any Guarantor, as applicable, or of any officer or
officers thereof required by the provisions of this Article X.

     SECTION 10.09. Determinations Relating to Collateral. In the event (i) the
Trustee shall receive any written request from the Issuer or any Guarantor or
the Collateral Agent under any Collateral Document for consent or approval with
respect to any matter or thing relating to any Collateral or the Issuer's or any
Guarantor's obligations with respect thereto; (ii) there shall be required from
the Trustee under the provisions of any Collateral Document any performance or
the delivery of any instrument or (iii) a Responsible Officer of the Trustee
shall become aware of any nonperformance by the Issuer or any Guarantor of any
covenant or any breach of any representation or warranty of the Issuer or any
Guarantor set forth in any Collateral Document, and, in the case of clause (i),
(ii) or (iii) above, the Trustee's response or action is not otherwise
specifically contemplated hereunder then, in each such event, the Trustee shall,
within seven Business Days, advise the Holders, in writing and at the Issuer's
expense, of the matter or thing as to which consent has been requested or the
performance or instrument required to be delivered or the nonperformance or
breach of which the Trustee has become aware. The Holders of not less than a
majority in aggregate principal amount of the outstanding Debentures pursuant to
Section 6.05 shall have the exclusive authority to direct the Trustee's response
to any of the circumstances contemplated in clauses (i), (ii) and (iii) above.
In the event the Trustee shall be required to respond to any of the
circumstances contemplated in this Section 10.09, the Trustee shall not be
required so to respond unless it shall have received written authority by not
less than a majority in aggregate principal amount of the outstanding
Debentures; provided that the Trustee shall be entitled to hire experts,
consultants, agents and attorneys to advise the Trustee on the manner in which
the Trustee should respond to such request or render any requested performance
or response to such nonperformance or breach (the expenses of which shall be
reimbursed to the Trustee pursuant to Section 7.07). The Trustee shall be fully
protected in the taking of any action recommended or approved by any such
expert, consultant, agent or attorney or agreed to by a majority of Holders of
the Debentures pursuant to Section 6.05.

     SECTION 10.10. Release upon Termination of the Issuer's Obligations. In the
event that the Issuer delivers an Officers' Certificate certifying that its
obligations under this Indenture have been satisfied and discharged by complying
with the provisions of Article VIII

                                      -61-
<PAGE>
and such other documents and/or funds as are required to be delivered or paid
pursuant to Article VIII, the Trustee shall (i) execute and deliver, in each
case without recourse, representation or warranty such releases, termination
statements and other instruments (in recordable form, appropriate) as the Issuer
or any Guarantor, as applicable, may reasonably request evidencing the
termination of the Security Interests created by the Collateral Documents and
(ii) not be deemed to hold the Security Interests for the benefit of the Trustee
and the Holders.

                                   ARTICLE XI

                              DEBENTURE GUARANTEES

     SECTION 11.01. Debenture Guarantees. Each Guarantor hereby jointly and
severally unconditionally and irrevocably agrees to be liable, as a primary
obligor and co-issuer, and not merely as a surety, to each Holder and to the
Trustee and its successors and assigns for (a) the full and punctual payment of
principal of, premium, if any, and interest, if any, on the Debentures when due,
whether at maturity, by acceleration or otherwise, subject to any applicable
grace period, and all other monetary obligations of the Issuer under this
Indenture (including obligations to the Trustee) and the Debentures and (b) the
full and punctual performance within applicable grace periods of all other
obligations of the Issuer whether for expenses, indemnification or otherwise
under this Indenture and the Debentures (all of the foregoing being hereinafter
collectively called the "Guaranteed Obligations"). Each Guarantor further agrees
that the Guaranteed Obligations may be extended or renewed, in whole or in part,
without notice or further assent from each such Guarantor, and that each such
Guarantor shall remain bound under this Article XI notwithstanding any extension
or renewal of any Guaranteed Obligation.

     Each Guarantor waives presentation to, demand of, payment from and protest
to the Issuer of any of the Guaranteed Obligations and also waives notice of
protest for nonpayment. Each Guarantor waives notice of any default under the
Debentures or the Guaranteed Obligations. The obligations of each Guarantor
hereunder shall not be affected by (a) the failure of any Holder or the Trustee
to assert any claim or demand or to enforce any right or remedy against the
Issuer or any other Person under this Indenture, the Debentures or any other
agreement or otherwise; (b) any extension or renewal of any Guaranteed
Obligations; (c) any rescission, waiver, amendment or modification of any of the
terms or provisions of this Indenture, the Debentures or any other agreement;
(d) the release of any security held by any Holder or the Trustee for the
Guaranteed Obligations or any of them; (e) the failure of any Holder or Trustee
to exercise any right or remedy against any other Guarantor of the Guaranteed
Obligations; or (f) any change in the ownership of such Guarantor, except as
provided in Section 11.02(b).

                                      -62-
<PAGE>
     Each Guarantor further agrees that its Debenture Guarantee herein
constitutes an obligation, as co-issuer of the Debentures, to make payment,
perform and comply when due (and not a guarantee of collection) and waives any
right to require that any resort be had by any Holder or the Trustee to any
security held for payment of the Guaranteed Obligations.

     The obligations of each Guarantor hereunder shall not be subject to any
reduction, limitation, impairment or termination for any reason, including any
claim of waiver, release, surrender, alteration or compromise, and shall not be
subject to any defense of setoff, counterclaim, recoupment or termination
whatsoever or by reason of the invalidity, illegality or unenforceability of the
Guaranteed Obligations or otherwise. Without limiting the generality of the
foregoing, the obligations of each Guarantor herein shall not be discharged or
impaired or otherwise affected by the failure of any Holder or the Trustee to
assert any claim or demand or to enforce any remedy under this Indenture, the
Debentures or any other agreement, by any waiver or modification of any thereof,
by any default, failure or delay, willful or otherwise, in the performance of
the Guaranteed Obligations, or by any other act or thing or omission or delay to
do any other act or thing which may or might in any manner or to any extent vary
the risk of any Guarantor or would otherwise operate as a discharge of any
Guarantor as a matter of law or equity.

     Each Guarantor further agrees that its Debenture Guarantee herein shall
continue to be effective or be reinstated, as the case may be, if at any time
payment, or any part thereof, of principal of or interest on any Guaranteed
Obligation is rescinded or must otherwise be restored by any Holder or the
Trustee upon the bankruptcy or reorganization of the Issuer or otherwise.

     In furtherance of the foregoing and not in limitation of any other right
which any Holder or the Trustee has at law or in equity against any Guarantor by
virtue hereof, upon the failure of the Issuer to pay the principal of or
interest, or premium, if any, on any Guaranteed Obligation when and as the same
shall become due, whether at maturity, by acceleration or otherwise, or to
perform or comply with any other Guaranteed Obligation, each Guarantor hereby
promises to and shall, upon receipt of written demand by the Trustee, forthwith
pay, or cause to be paid, in cash, to the Holders or the Trustee an amount equal
to the sum of (i) the unpaid principal amount of such Guaranteed Obligations,
(ii) accrued and unpaid interest and premium, if any, on such Guaranteed
Obligations (but only to the extent not prohibited by law) and (iii) all other
monetary Guaranteed Obligations of the Issuer to the Holders and the Trustee.

     Each Guarantor agrees that it shall not be entitled to any right of
subrogation in relation to the Holders in respect of any Guaranteed Obligations
which it is hereby obligated as co-issuer until payment in full of all
Guaranteed Obligations. Each Guarantor further agrees that, as between it, on
the one hand, and the Holders and the Trustee, on the other

                                      -63-
<PAGE>
hand, (x) the maturity of the Guaranteed Obligations which it is hereby
obligated as co-issuer may be accelerated as provided in Article VI for the
purposes of any Debenture Guarantee herein, notwithstanding any stay, injunction
or other prohibition preventing such acceleration in respect of the Guaranteed
Obligations guaranteed hereby, and (y) in the event of any declaration of
acceleration of such Guaranteed Obligations as provided in Article VI, such
Guaranteed Obligations (whether or not due and payable) shall forthwith become
due and payable by such Guarantor for the purposes of this Section.

     Each Guarantor also agrees to pay any and all costs and expenses (including
reasonable attorneys' fees and expenses) incurred by the Trustee or any Holder
in enforcing any rights under this Section.

     SECTION 11.02. Limitation on Liability; Release. (a) Any term or provision
of this Indenture to the contrary notwithstanding, the maximum, aggregate amount
of the obligations any Guarantor is hereunder obligated as co-issuer shall not
exceed the maximum amount that such Guarantor can be so obligated as co-issuer
(after giving effect to all its Guarantees of Debt under the Senior Debt)
without rendering this Indenture, as it relates to any Guarantor, voidable under
applicable law relating to fraudulent conveyance or fraudulent transfer or
similar laws affecting the rights of creditors generally.

     (b) This Guarantee as to any Subsidiary Guarantor shall terminate and be of
no further force or effect, and any such Subsidiary Guarantor shall be released
and relieved of any obligations under its Debenture Guarantee and this
Indenture, upon (i) the designation (in accordance with the provisions of this
Indenture) of such Subsidiary Guarantor as an Unrestricted Subsidiary or (ii)
the sale or other disposition of all of the assets of such Subsidiary Guarantor
in accordance with the terms of this Indenture, by way of merger, consolidation
or otherwise, or a sale or other disposition of all of the Capital Stock of any
Subsidiary Guarantor then held by the Issuer and its Restricted Subsidiaries; or
(iii) the sale or other disposition of Capital Stock of any Subsidiary Guarantor
if as a result of such disposition, such Person ceases to be a Subsidiary of the
Issuer. If the Debenture Guarantee of any Subsidiary Guarantor terminates
pursuant to the foregoing provisions, such Person shall cease to be a
Subsidiary, a Guarantor or otherwise a party to this Indenture and, upon request
by the Issuer, the Trustee shall execute appropriate instruments acknowledging
such termination and the release of such Person from its obligations hereunder.

     SECTION 11.03. Successors and Assigns. This Article XI shall be binding
upon each Guarantor and its successors and assigns and shall enure to the
benefit of the successors and assigns of the Trustee and the Holders and, in the
event of any transfer or assignment of rights by any Holder or the Trustee, the
rights and privileges conferred upon that party in this Indenture and in the
Debentures shall automatically extend to and be vested in such transferee or
assignee, all subject to the terms and conditions of this Indenture.

                                      -64-
<PAGE>
     SECTION 11.04. No Waiver. Neither a failure nor a delay on the part of
either the Trustee or the Holders in exercising any right, power or privilege
under this Article XI shall operate as a waiver thereof, nor shall a single or
partial exercise thereof preclude any other or further exercise of any right,
power or privilege. The rights, remedies and benefits of the Trustee and the
Holders herein expressly specified are cumulative and not exclusive of any other
rights, remedies or benefits which either may have under this Article XI at law,
in equity, by statute or otherwise.

     SECTION 11.05. Modification. No modification, amendment or waiver of any
provision of this Article XI, nor the consent to any departure by any Guarantor
therefrom, shall in any event be effective unless the same shall be in writing
and signed by the Trustee, and then such waiver or consent shall be effective
only in the specific instance and for the purpose for which given. No notice to
or demand on any Guarantor in any case shall entitle such Guarantor to any other
or further notice or demand in the same, similar or other circumstances.

     SECTION 11.06. Evidence of Guarantee. To evidence their obligations as
co-issuers of the Debentures to the Holders set forth in this Article XI, each
of the Guarantors hereby agrees to execute the notation of Debenture Guarantee
in substantially the form included in Exhibit B. Each such notation of Debenture
Guarantee shall be signed on behalf of each Guarantor by an Officer.

     Each Guarantor hereby agrees that its Debenture Guarantee set forth in
Section 11.01 shall remain in full force and effect notwithstanding any failure
to endorse on each Debenture a notation of such Debenture Guarantee.

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

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

                                   ARTICLE XII

                                  SUBORDINATION

     The Debentures are subordinate in right and priority to the prior payment
in full of Senior Debt, as follows:

                                      -65-
<PAGE>
     Section 12.01. Subordination. The Issuer agrees, and each Holder by
accepting a Debenture agrees, that the Indebtedness evidenced by the Debentures
(including principal of, premium, if any, interest on and all other amounts with
respect to the Debentures) is subordinated in right of payment, to the extent
and in the manner provided in this Article XII, to the prior payment in full in
cash of all Senior Debt (whether outstanding on the date hereof or hereafter
created, incurred, assumed or guaranteed), and that the subordination is for the
benefit of the holders of Senior Debt.

     Section 12.02. Distributions in Liquidation or Bankruptcy. Upon any
distribution to creditors of the Issuer in a liquidation or dissolution of the
Issuer or in a bankruptcy, reorganization, insolvency, receivership or similar
proceeding relating to the Issuer or its property, in an assignment for the
benefit of creditors or any marshaling of the Issuer's assets and liabilities:

     (a) holders of Senior Debt will be entitled to receive payment in full in
cash of all Obligations due in respect of such Senior Debt (including interest
after the commencement of any bankruptcy proceeding at the rate specified in the
applicable Senior Debt) before the Holders of Debentures will be entitled to
receive any payment with respect to the Debentures (except that Holders of
Debentures may receive and retain payments made from any defeasance trust
created pursuant to Section 8.03 hereof); and

     (b) until all Obligations with respect to Senior Debt (as provided in the
preceding clause (a) above) are paid in full, any distribution to which Holders
would be entitled but for this Article XII will be made to holders of Senior
Debt (except payments made from any defeasance trust created pursuant to Section
8.03 hereof), as their interests may appear.

     Section 12.03. Prior Payment of Senior Debt; Payment Blockages. The Issuer
may not make any payment or distribution to the Trustee or any Holder in respect
of Obligations under the Debentures (other than payments made from any
defeasance trust created pursuant to Section 8.03 hereof) until all principal
and other Obligations with respect to the Senior Debt have been paid in full if:

     (a) a payment default on Senior Debt occurs and is continuing beyond any
applicable grace period in the agreement, indenture or other document governing
such Senior Debt; or

     (b) any other default occurs and is continuing on any series of Senior Debt
that permits holders of that series of Senior Debt to accelerate its maturity
and the Trustee receives a notice of such default (a "Payment Blockage Notice")
from the Issuer or the holders of any Senior Debt. If the Trustee receives any
such Payment Blockage Notice, no subsequent Payment Blockage Notice will be
effective for purposes of this Section unless and until (A) at

                                      -66-
<PAGE>
least 365 days have elapsed since the effectiveness of the immediately prior
Payment Blockage Notice and (B) all scheduled payments of principal, premium, if
any, and interest on the Debentures that have come due have been paid in full in
cash.

     No nonpayment default that existed or was continuing on the date of
delivery of any Payment Blockage Notice to the Trustee may be, or may be made,
the basis for a subsequent Payment Blockage Notice unless such default has have
been cured or waived for a period of not less than 90 days.

     Section 12.04. Resumption of Payments on Debentures. The Issuer may and
will resume payments on and distributions in respect of the Debentures upon the
earlier of:

     (a) in the case of a payment default on Senior Debt, upon the date upon
which such default is cured or waived, or

     (b) in the case of a nonpayment default on Senior Debt, upon the earliest
of: (i) the date on which such nonpayment default is cured or waived, (ii) 179
days after the date on which the applicable Payment Blockage Notice is received,
unless the maturity of any Senior Debt has been accelerated and such Senior Debt
remains due and unpaid, or (iii) the date on which the Trustee receives notice
from the holder of such Senior Debt rescinding such Payment Blockage Notice, if
this Article XII otherwise permits the payment, distribution or acquisition at
the time of such payment or acquisition.

     Section 12.05. Notice of Acceleration. If payment of the Debentures is
accelerated because of an Event of Default, the Issuer will promptly notify
holders of Senior Debt of the acceleration.

     Section 12.06. Payments Held in Trust. In the event that the Trustee or any
Holder receives any payment of any Obligations with respect to the Debentures
(other than payments made from any defeasance trust created pursuant to Section
8.03 hereof) at a time when the Trustee or such Holder, as applicable, has
actual knowledge that such payment is prohibited by this Article XII, such
payment will be held by the Trustee or such Holder, in trust for the benefit of,
and will be paid forthwith over and delivered, upon written request, to, the
holders of Senior Debt as their interests may appear or their representative or
agent under the agreement, indenture or other document (if any) pursuant to
which Senior Debt may have been issued, as their respective interests may
appear, for application to the payment of all Obligations with respect to Senior
Debt remaining unpaid to the extent necessary to pay such Obligations in full in
accordance with their terms, after giving effect to any concurrent payment or
distribution to or for the holders of Senior Debt.

                                      -67-
<PAGE>
     Section 12.07. Duties of Trustee. With respect to the holders of Senior
Debt, the Trustee undertakes to perform only those obligations on the part of
the Trustee as are specifically set forth in this Article XII, and no implied
covenants or obligations with respect to the holders of Senior Debt will be read
into this Indenture against the Trustee. The Trustee will not be deemed to owe
any fiduciary duty to the holders of Senior Debt, and will not be liable to any
such holders if the Trustee pays over or distributes to or on behalf of Holders
or the Issuer or any other Person money or assets to which any holders of Senior
Debt are then entitled by virtue of this Article XII, except if such payment is
made as a result of the willful misconduct or gross negligence of the Trustee.

     Section 12.08. Notice of Violations. The Issuer will promptly notify the
Trustee and the Paying Agent of any facts known to the Issuer that would cause a
payment of any Obligations with respect to the Debentures to violate this
Article XII, but failure to give such notice will not affect the subordination
of the Debentures to the Senior Debt as provided in this Article XII.

     Section 12.09. Subrogation. After all Senior Debt is paid in full and until
the Debentures are paid in full, Holders of Debentures will be subrogated
(equally and ratably with all other Indebtedness pari passu with the Debentures)
to the rights of holders of Senior Debt to receive distributions applicable to
Senior Debt to the extent that distributions otherwise payable to the Holders of
Debentures have been applied to the payment of Senior Debt. A distribution made
under this Article XII to holders of Senior Debt that otherwise would have been
made to Holders of Debentures is not, as between the Issuer and Holders, a
payment by the Issuer on the Debentures.

     Section 12.10. No Impairment. This Article XII defines the relative rights
of Holders of Debentures and holders of Senior Debt. Nothing in this Indenture
will:

     (a) impair, as between the Issuer and Holders of Debentures, the obligation
of the Issuer, which is absolute and unconditional, to pay principal of,
premium, if any, and interest on the Debentures in accordance with their terms;

     (b) affect the relative rights of Holders of Debentures and creditors of
the Issuer other than their rights in relation to holders of Senior Debt; or

     (c) prevent the Trustee or any Holder of Debentures from exercising its
available remedies upon a Default or Event of Default, subject to the rights of
holders and owners of Senior Debt to receive distributions and payments
otherwise payable to Holders of Debentures.

                                      -68-
<PAGE>
If the Issuer fails because of this Article XII to pay principal of, premium, if
any, and interest on a Debenture on the due date, the failure is still a Default
or Event of Default.

     Section 12.11. Right of Senior Debt to Enforce. No right of any holder of
Senior Debt to enforce the subordination of the Indebtedness evidenced by the
Debentures may be impaired by any act or failure to act by the Issuer or any
Holder or by the failure of the Issuer or any Holder to comply with this
Indenture.

     Section 12.12. Notice to Senior Debt. Whenever a distribution is to be made
or a notice given to holders of Senior Debt, the distribution may be made and
the notice given to such holders, or their representative or agent. Upon any
payment or distribution of assets of the Issuer referred to in this Article XII,
the Trustee and the Holders of Debentures will be entitled to rely upon any
order or decree made by any court of competent jurisdiction or upon any
certificate of such representative or of the liquidating trustee or agent or
other Person making any distribution to the Trustee or to the Holders of
Debentures for the purpose of ascertaining the Persons entitled to participate
in such distribution, the holders of the Senior Debt and other Indebtedness of
the Issuer, the amount thereof or payable thereon, the amount or amounts paid or
distributed thereon and all other facts pertinent thereto or to this Article
XII.

     Section 12.13. Knowledge of Trustee. The provisions of this Article XII or
any other provision of the Indenture notwithstanding, the Trustee will not be
charged with knowledge of the existence of any facts that would prohibit the
making of any payment or distribution by the Trustee, and the Trustee and the
Paying Agent may continue to make payments on the Debentures, unless the Trustee
has received at its Corporate Trust Office at least five Business Days prior to
the date of such payment written notice of facts that would cause the payment of
any Obligations with respect to the Debentures to violate this Article XII. Only
the Issuer or a representative or agent of holders of Senior Debt may give the
notice. Nothing in this Article XII will impair the claims of, or payments to,
the Trustee under or pursuant to Section 7.07.

     Section 12.14. Trustee May Hold Senior Debt. The Trustee in its individual
or any other capacity may hold Senior Debt with the same rights it would have if
it were not Trustee. Any Agent may do the same with like rights.

     Section 12.15. Power of Attorney. Each Holder of Debentures, by the
Holder's acceptance thereof, authorizes and directs the Trustee on such Holder's
behalf to take such action as may be necessary or appropriate to effectuate the
subordination as provided in this Article XII, and appoints the Trustee to act
as such Holder's attorney-in-fact for any and all such purposes. If the Trustee
does not file a proper proof of claim or proof of debt in the form required in
any proceeding referred to in Sections 6.01(a)(9) and (10) of the Indenture at
least 30 days before the expiration of the time to file such claim, the
representatives or agent of the

                                      -69-
<PAGE>
Secured Debt are hereby authorized to file an appropriate claim for and on
behalf of the Holders of the Debentures.

     Section 12.16. Modification. The provisions of this Article XII may not be
amended or modified without the written consent of the holders of all Senior
Debt.

                                  ARTICLE XIII

                           SUBORDINATION OF GUARANTEES

     Each Guarantee is subordinate in right and priority to the prior payment in
full of Senior Debt of each such Guarantor, as follows:

     Section 13.01. Subordination. Each Guarantor agrees, and each Holder by
accepting a Debenture agrees, that such Guarantor's Obligations under its
Guarantee are subordinated in right of payment, to the extent and in the manner
provided in this Article XIII, to the prior payment in full in cash of all
Senior Debt of the Guarantor (whether outstanding on the date hereof or
hereafter created, incurred, assumed or guaranteed), and that the subordination
is for the benefit of the holders of Senior Debt of the Guarantor.

     Section 13.02. Distributions in Liquidation or Bankruptcy. Upon any
distribution to creditors of a Guarantor in a liquidation or dissolution of such
Guarantor or in a bankruptcy, reorganization, insolvency, receivership or
similar proceeding relating to such Guarantor or its property, in an assignment
for the benefit of creditors or any marshaling of the Guarantor's assets and
liabilities:

     (a) holders of Senior Debt of the Guarantor will be entitled to receive
payment in full in cash of all Obligations due in respect of such Senior Debt
(including interest after the commencement of any bankruptcy proceeding at the
rate specified in the applicable Senior Debt) before the Holders of Debentures
will be entitled to receive any payment with respect to the Debentures or the
Guarantees (except that Holders of Debentures may receive and retain payments
made from any defeasance trust created pursuant to Section 8.03 hereof); and

     (b) until all Obligations with respect to Senior Debt of the Guarantor (as
provided in the preceding clause (a) above) are paid in full, any distribution
to which Holders would be entitled but for this Article XIII will be made to
holders of Senior Debt (except payments made from any defeasance trust created
pursuant to Section 8.03 hereof), as their interests may appear.

     Section 13.03. Prior Payment of Senior Debt; Payment Blockages. A Guarantor
may not make any payment or distribution to the Trustee or any Holder in respect
of Obligations

                                      -70-
<PAGE>
under its Guarantee (other than payments made from any defeasance trust created
pursuant to Section 8.03 hereof) until all principal and other Obligations with
respect to the Senior Debt of the Guarantor have been paid in full if:

     (a) a payment default on Senior Debt occurs and is continuing beyond any
applicable grace period in the agreement, indenture or other document governing
such Senior Debt; or

     (b) any other default occurs and is continuing on any series of Senior Debt
that permits holders of that series of Senior Debt to accelerate its maturity
and the Trustee receives a notice of such default (a "Guarantor Payment Blockage
Notice") from the Guarantor or the holders of any Senior Debt. If the Trustee
receives any such Guarantor Payment Blockage Notice, no subsequent Guarantor
Payment Blockage Notice will be effective for purposes of this Section unless
and until (A) at least 365 days have elapsed since the effectiveness of the
immediately prior Guarantor Payment Blockage Notice and (B) all scheduled
payments of principal, premium, if any, and interest on the Debentures that have
come due have been paid in full in cash.

     No nonpayment default that existed or was continuing on the date of
delivery of any Guarantor Payment Blockage Notice to the Trustee may be, or may
be made, the basis for a subsequent Guarantor Payment Blockage Notice unless
such default has have been cured or waived for a period of not less than 90
days.

     Section 13.04. Resumption of Payments on Guarantees. The Issuer may and
will resume payments on and distributions in respect of the Debentures upon the
earlier of:

     (a) in the case of a Guarantor payment default on Senior Debt, upon the
date upon which such default is cured or waived, or

     (b) in the case of a Guarantor nonpayment default on Senior Debt, upon the
earliest of: (i) the date on which such nonpayment default is cured or waived,
(ii) 179 days after the date on which the applicable Guarantor Payment Blockage
Notice is received, unless the maturity of any Senior Debt has been accelerated
and such Senior Debt remains due and unpaid, or (iii) the date on which the
Trustee receives notice from the holder of such Senior Debt rescinding such
Guarantor Payment Blockage Notice, if this Article XIII otherwise permits the
payment, distribution or acquisition at the time of such payment or acquisition.

     Section 13.05. Notice of Acceleration. If payment of the Debentures is
accelerated because of an Event of Default and demand is made on a Guarantor for
payment pursuant to Article XI, the Guarantor will promptly notify holders of
Senior Debt of the Guarantor of the acceleration.

                                      -71-
<PAGE>
     Section 13.06. Payments Held in Trust. In the event that the Trustee or any
Holder receives any payment of any Obligations with respect to a Guarantee
(other than payments made from any defeasance trust created pursuant to Section
8.03 hereof) at a time when the Trustee or such Holder, as applicable, has
actual knowledge that such payment is prohibited by this Article XIII, such
payment will be held by the Trustee or such Holder, in trust for the benefit of,
and will be paid forthwith over and delivered, upon written request, to, the
holders of Senior Debt of such Guarantor as their interests may appear or their
representative or agent under the agreement, indenture or other document (if
any) pursuant to which such Senior Debt may have been issued, as their
respective interests may appear, for application to the payment of all
Obligations with respect to such Senior Debt remaining unpaid to the extent
necessary to pay such Obligations in full in accordance with their terms, after
giving effect to any concurrent payment or distribution to or for the holders of
such Senior Debt.

     Section 13.07. Duties of Trustee. With respect to the holders of Senior
Debt of a Guarantor, the Trustee undertakes to perform only those obligations on
the part of the Trustee as are specifically set forth in this Article XIII, and
no implied covenants or obligations with respect to the holders of Senior Debt
of a Guarantor will be read into this Indenture against the Trustee. The Trustee
will not be deemed to owe any fiduciary duty to the holders of Senior Debt of a
Guarantor, and will not be liable to any such holders if the Trustee pays over
or distributes to or on behalf of Holders or the Issuer or any other Person
money or assets to which any holders of Senior Debt of a Guarantor are then
entitled by virtue of this Article XIII, except if such payment is made as a
result of the willful misconduct or gross negligence of the Trustee.

     Section 13.08. Notice of Violations. The Issuer or the applicable Guarantor
will promptly notify the Trustee and the Paying Agent of any facts known to the
Issuer or such Guarantor that would cause a payment of any Obligations with
respect to the Debentures or the Guarantee of such Guarantor to violate this
Article XIII, but failure to give such notice will not affect the subordination
of the Guarantees to the Senior Debt as provided in this Article XIII.

     Section 13.09. Subrogation. After all Senior Debt of a Guarantor is paid in
full and until the Debentures are paid in full, Holders of Debentures will be
subrogated (equally and ratably with all other Indebtedness pari passu with the
Debentures) to the rights of holders of Senior Debt of such Guarantor to receive
distributions applicable to such Senior Debt to the extent that distributions
otherwise payable to the Holders of Debentures have been applied to the payment
of Senior Debt. A distribution made under this Article XIII to holders of Senior
Debt of such Guarantor that otherwise would have been made to Holders of
Debentures is not, as between such Guarantor and Holders, a payment by such
Guarantor on the Debentures.

                                      -72-
<PAGE>
     Section 13.10. No Impairment. This Article XIII defines the relative rights
of Holders of Debentures and holders of Senior Debt of a Guarantor. Nothing in
this Indenture will:

     (a) impair, as between a Guarantor and Holders of Debentures, the
obligation of a Guarantor, which is absolute and unconditional, to pay its
Obligations under its Guarantee in accordance with its terms;

     (b) affect the relative rights of Holders of Debentures and creditors of a
Guarantor other than their rights in relation to holders of Senior Debt of such
Guarantor; or

     (c) prevent the Trustee or any Holder of Debentures from exercising its
available remedies upon a Default or Event of Default, subject to the rights of
holders and owners of Senior Debt of such Guarantor to receive distributions and
payments otherwise payable to Holders of Debentures.

If a Guarantor fails because of this Article XIII to pay principal of, premium,
if any, and interest on a Debenture on the due date pursuant to its Guarantee,
the failure is still a Default or Event of Default.

     Section 13.11. Right of Senior Debt to Enforce. No right of any holder of
Senior Debt of a Guarantor to enforce the subordination of the Indebtedness
evidenced by the Guarantee of such Guarantor may be impaired by any act or
failure to act by such Guarantor or any Holder or by the failure of such
Guarantor or any Holder to comply with this Indenture.

     Section 13.12. Notice to Senior Debt. Whenever a distribution is to be made
or a notice given to holders of Senior Debt of a Guarantor, the distribution may
be made and the notice given to such holders, or their representative or agent.
Upon any payment or distribution of assets of a Guarantor referred to in this
Article XIII, the Trustee and the Holders of Debentures will be entitled to rely
upon any order or decree made by any court of competent jurisdiction or upon any
certificate of such representative or of the liquidating trustee or agent or
other Person making any distribution to the Trustee or to the Holders of
Debentures for the purpose of ascertaining the Persons entitled to participate
in such distribution, the holders of the Senior Debt and other Indebtedness of
such Guarantor, the amount thereof or payable thereon, the amount or amounts
paid or distributed thereon and all other facts pertinent thereto or to this
Article XIII.

     Section 13.13. Knowledge of Trustee. The provisions of this Article XIII or
any other provision of the Indenture notwithstanding, the Trustee will not be
charged with knowledge of the existence of any facts that would prohibit the
making of any payment or distribution by the Trustee, and the Trustee and the
Paying Agent may continue to make payments on the Debentures, unless the Trustee
has received at its Corporate Trust Office at least five Business

                                      -73-
<PAGE>
Days prior to the date of such payment written notice of facts that would cause
the payment of any Obligations with respect to the Debentures to violate this
Article XIII. Only the Issuer or a representative or agent of holders of Senior
Debt may give the notice. Nothing in this Article XIII will impair the claims
of, or payments to, the Trustee under or pursuant to Section 7.07.

     Section 13.14. Trustee May Hold Senior Debt. The Trustee in its individual
or any other capacity may hold Senior Debt of a Guarantor with the same rights
it would have if it were not Trustee. Any Agent may do the same with like
rights.

     Section 13.15. Power of Attorney. Each Holder of Debentures, by the
Holder's acceptance thereof, authorizes and directs the Trustee on such Holder's
behalf to take such action as may be necessary or appropriate to effectuate the
subordination as provided in this Article XIII, and appoints the Trustee to act
as such Holder's attorney-in-fact for any and all such purposes. If the Trustee
does not file a proper proof of claim or proof of debt in the form required in
any proceeding referred to in Sections 6.01(a)(10) and (11) of the Indenture at

<PAGE>
be disregarded and deemed not to be outstanding, except that, for the purpose of
determining whether the Trustee shall be protected in relying on any such
direction, waiver or consent, only Debentures which the Trustee actually knows

Debentures outstanding at the time shall be considered in any such
determination.

Registration Rights Agreement or the Collateral Documents or for any claim based

liability. The waiver and release shall be part of the consideration for the
issue of the Debentures.

in this Indenture and the Debentures shall bind their successors. All agreements
of the Trustee in this Indenture shall bind its successors.

                8% Class B Junior Subordinated Secured Debenture

1.   INTEREST

     UMT HOLDINGS, L.P., a Delaware limited partnership (the "Issuer"), promises
to pay interest on the principal amount of this Debenture at the rate per annum
shown above.

     The Issuer will pay interest monthly in arrears on the second to last
Business Day of each month commencing on May 27, 2004. Interest on the
Debentures will accrue from the most recent date to which interest has been paid
or, if no interest has been paid, from the Issue Date with respect to this
Debenture. Interest will be computed on the basis of a 365-day year; provided
that in leap years interest will be computed on the basis of a 366-day year. The
Issuer shall pay interest on overdue principal at the rate borne by the
Debentures plus 1% per annum, and it shall pay interest on overdue installments
of interest at the same rate to the extent lawful.

2.   METHOD OF PAYMENT

     The Issuer will pay interest (except defaulted interest) on the Debentures
to the Persons who are registered holders of Debentures at the close of business
on the last Business Day of the immediately preceding month even if Debentures
are canceled after the record date and on or before the interest payment date.
Holders must surrender Debentures to a Paying Agent to collect principal
payments. The Issuer will pay principal and interest in money of the United
States that at the time of payment is legal tender for payment of public and
private debts. However, the Issuer may pay principal and interest by check
payable in such money or by wire transfer of federal funds.

3.   PAYING AGENT AND REGISTRAR

     Initially, WILMINGTON TRUST COMPANY (the "Trustee") will act as Paying
Agent and Registrar. The Issuer may appoint and change any Paying Agent,
Registrar or co-registrar without notice to the Holders. The Issuer or any
domestically organized Wholly Owned Restricted Subsidiary may act as Paying
Agent, Registrar or co-registrar.

4.   INDENTURE

     The Issuer issued the Debentures under an Indenture dated as of April 21,
2004 (the "Indenture"), among the Issuer, the Guarantors and the Trustee. The
terms of the Debentures include those stated in the Indenture and those made
part of the Indenture by reference to the TIA. Terms defined in the Indenture
and not defined herein have the meanings ascribed thereto in the Indenture. The
Debentures are subject to all such terms, and Debentureholders are referred to
the Indenture and the TIA for a statement of those terms.

                                      A-4
<PAGE>
     The Debentures are junior subordinated secured obligations of the Issuer
and are limited to $25,000,000 in aggregate principal amount outstanding. This
Debenture is one of the Debentures referred to in the Indenture. The Indenture
imposes certain limitations on the lines of business in which the Issuer and its
Restricted Subsidiaries may operate; Liens; and consolidations, mergers and
transfers of all or substantially all of the Issuer's or a Guarantor's assets.
In addition, the Indenture prohibits certain restrictions on distributions from
Restricted Subsidiaries.

5.   NOTICES AND REDEMPTION

     The Debentures may not be redeemed prior to April 1, 2007. Thereafter, the
Debentures will be subject to redemption at any time at the option of the
Issuer, in whole or in part, upon not less than 30 nor more than 60 days notice,
at 100% of the principal amount plus accrued and unpaid interest to the
applicable redemption date (subject to the right of Holders on the relevant
record date to receive interest due on the relevant interest payment date).

6.   NOTICES OF REDEMPTION

     Except as otherwise provided in the Indenture or herein, notices of
redemption shall be mailed by first-class mail at least 30 days but not more
than 60 days before the redemption date to each Holder of Debentures to be
redeemed at its registered address all in with the Indenture. If less than all
of the Debentures are to be redeemed at any time, selection of Debentures for
redemption will be made by the Trustee in compliance with the requirements of
the principal national Debentures exchange, if any, on which the Debentures are
listed, or, if the Debentures are not so listed, on a pro rata basis, by lot or
by such method as the Trustee shall deem fair and appropriate; provided that no
Debentures of $1,000 or less shall be redeemed in part; provided further,
however, that if a partial redemption is made with the proceeds of a public
offering of common stock, selection of the Debentures or portions thereof for
redemption shall be made by the Trustee on a pro rata basis only or on as nearly
a pro rata basis as is practicable, unless such method is otherwise prohibited.
If any Debenture is to be redeemed in part only, the notice of redemption that
relates to such Debenture shall state the portion of the principal amount
thereof to be redeemed. On and after the redemption date, interest ceases to
accrue on Debentures or portions of them called for redemption.

7.   COLLATERAL DOCUMENTS

     In order to secure the due and punctual payment of the principal of and
interest on the Debentures and all other amounts payable by the Issuer and the
Subsidiary Guarantors under the Indenture and the Debentures when and as the
same shall be due and payable, whether at maturity, by acceleration or
otherwise, according to the terms of the Debentures and the Indenture,
Guarantors have granted Liens on the Collateral to the Collateral Agent for the
benefit of the Trustees and Holders of Debentures, pursuant to the Indenture and
the Collateral Documents.

                                      A-5
<PAGE>
     Each Holder, by accepting a Debenture, agrees to all of the terms and
provisions of the Collateral Documents as the same may be amended from time to
time pursuant to the respective provisions thereof and the Indenture.

     The Trustee and each Holder acknowledge that a release of any of the
Collateral or any Lien strictly in accordance with the terms and provisions of
any of the Collateral Documents and the terms and provisions of the Indenture
will not be deemed for any purpose to be an impairment of the security under the
Indenture.

8.   SUBORDINATION

     The Debentures are subordinated to Senior Debt of the Company, as defined
in the Indenture. To the extent provided in the Indenture, Senior Debt of the
Company must be paid before the Debentures may be paid. The Company agrees, and
each Debentureholder by accepting a Debenture agrees, to the subordination
provisions contained in the Indenture and authorizes the Trustee to give it
effect and appoints the Trustee as attorney-in-fact for such purpose.

9.   DENOMINATIONS; TRANSFER; EXCHANGE

     The Debentures are in registered form without coupons in denominations of
$1,000 and whole multiples of $1,000. A Holder may transfer or exchange
Debentures in accordance with the Indenture. Upon any transfer or exchange, the
Registrar and the Trustee may require a Holder, among other things, to furnish
appropriate endorsements or transfer documents and to pay any taxes required by
law or permitted by the Indenture. The Registrar need not register the transfer
of or exchange any Debentures selected for transfer or exchange for a period of
15 days before an interest payment date.

10.  PERSONS DEEMED OWNERS

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

11.  UNCLAIMED MONEY

     If money for the payment of principal or interest remains unclaimed for two
years, the Paying Agent shall pay the money back to the Issuer at its request,
or if then held by the Issuer or a Wholly Owned Restricted Subsidiary, shall be
discharged from such trust (unless an abandoned property law designates another
Person for payment thereof). After any such payment, Holders entitled to the
money must look only to the Issuer for payment thereof, and all liability of the
Paying Agent with respect to such money, and all liability of the Issuer or such
permitted Wholly Owned Restricted Subsidiary as trustee thereof, shall thereupon
cease.

                                      A-6
<PAGE>
12.  DISCHARGE AND DEFEASANCE

     Subject to certain conditions set forth in the Indenture, the Issuer at any
time may terminate some or all of its obligations under the Indenture, the
Debenture Guarantees, and the Debentures if the Issuer deposits with the Trustee
money or U.S. Government Obligations for the payment of principal and interest
on the Debentures to maturity.

13.  AMENDMENT, WAIVER

     Subject to certain exceptions set forth in the Indenture, (i) the
Indenture, the Debentures, the Debenture Guarantees or the Collateral Documents
may be amended or supplemented with the written consent of the Holders of at
least a majority in principal amount outstanding of the Debentures and (ii) any
existing default or noncompliance with any provision of the Indenture, the
Debentures, Debenture Guarantees, or the Collateral Documents (other than
payment of principal, premium, if any, and interest) may be waived with the
consent of the Holders of a majority in principal amount of the then outstanding
Debentures. Subject to certain exceptions set forth in the Indenture, without
the consent of any Debentureholder, the Issuer and the Trustee may amend or
supplement the Indenture, the Debentures, the Debenture Guarantees, or the
Collateral Documents to cure any ambiguity, defect or inconsistency, to provide
for uncertificated Debentures in addition to or in place of certificated
Debentures (provided that the uncertificated Debentures are issued in registered
form for purposes of Section 163(f) of the Code, or in a manner such that the
uncertificated Debentures are described in Section 163(f)(2)(B) of the Code), to
provide for the assumption of the Issuer's or any Guarantor's obligations to
Holders of Debentures in the case of a merger, consolidation or sale of assets,
to release any Debenture Guarantee or any Collateral or to release or
subordinate the Lien on any Collateral on account of Permitted Liens permitted
to be granted to third parties, or amend, restate and/or assign the Collateral
Documents in connection with a refinancing of the Senior Debt, in each case in
accordance with the provisions of the Indenture and the Collateral Documents, to
provide for additional Guarantors, to add Collateral, to make any change that
would provide any additional rights or benefits to the Holders of Debentures or
that, as determined by the General Partner of the Issuer in good faith, does not
materially adversely affect the legal rights of any such Holder under the
Indenture, the Debentures, the Debenture Guarantees or the Collateral Documents
or to comply with requirements of the SEC in order to effect or maintain the
qualification of the Indenture under the TIA.

14.  DEFAULTS AND REMEDIES

     Under the Indenture, an Event of Default occurs if there is: (i) default
for 30 days in the payment when due of interest on the Debentures; (ii) default
in payment when due of the principal of or premium, if any, on the Debentures;
(iii) failure by the Issuer (a) for 30 days after receipt of notice from the
Trustee or the Holders of at least 25% in principal amount of the then
outstanding Debentures to comply with Sections 5.01 or 5.02 of the Indenture or
(b) to comply with the provisions of Section 5.01 or 5.02 of the Indenture; (iv)

least 25% in aggregate principal amount of the then outstanding Debentures
specifying such failure to comply with any of its other agreements in the
Indenture or the Debentures; (v) the failure by the Issuer or any Restricted
Subsidiary that is a Significant Subsidiary to pay any Debt within any
applicable grace period after final maturity or acceleration by the holders
thereof because of a default if the total amount of all such Debt unpaid or
accelerated at the time exceeds $2 million; (vi) any judgment or decree for the
payment of money in excess of $10 million (net of any insurance or indemnity
payments actually received in respect thereof prior to or within 90 days from
the entry thereof, or to be received in respect thereof in the event any appeal
thereof shall be unsuccessful) is entered against the Issuer or any Significant
Subsidiary that is a Restricted Subsidiary and is not discharged, waived or
stayed and either (A) an enforcement proceeding has been commenced by any
creditor upon such judgment or decree or (B) there is a period of 90 days
following the entry of such judgment or decree during which such judgment or
decree is not discharged, waived or the execution thereof stayed; (vii) any
Debenture Guarantee shall be held in any judicial proceeding to be unenforceable
or invalid or, except as permitted by the Indenture, shall cease for any reason
to be in full force and effect or any Guarantor, or any Person acting on behalf
of any Guarantor, shall deny or disaffirm its obligations under its Debenture
Guarantee; (viii) default by the Issuer or any Subsidiary Guarantor in the
performance of the Collateral Documents which results in the unenforceability,
invalidity imperfection or lack of requisite priority of the Trustee's or the
Collateral Agent's Lien on Collateral with a fair market value in excess of $10
million, or the repudiation or disaffirmation by the Issuer or any Subsidiary
Guarantor of its obligations under the Collateral Documents or the determination
in a judicial proceeding that the Collateral Documents are unenforceable or
invalid against the Issuer or any Subsidiary Guarantor for any reason; (ix) an
event of default (as defined therein) has occurred and is continuing under the
Class A Indenture; or (x) certain events of bankruptcy or insolvency with
respect to the Issuer or any of its Restricted Subsidiaries that is a
Significant Subsidiary.

     Debentureholders may not enforce the Indenture or the Debentures except as
provided in the Indenture. The Trustee may refuse to enforce the Indenture or
the Debentures unless it receives indemnity or security reasonably satisfactory
to it. Subject to certain limitations, Holders of a majority in principal amount
of the Debentures may direct the Trustee in its exercise of any trust or power.
The Trustee may withhold from Debentureholders notice of any continuing Default
(except a Default in payment of principal, premium, if any, or interest) if and
so long as a committee of its Trust Officers in good faith determines that
withholding notice is in the interest of the Holders.

15.  TRUSTEE DEALINGS WITH THE ISSUER

     Subject to certain limitations imposed by the TIA, the Trustee under the
Indenture, in its individual or any other capacity, may become the owner or
pledgee of Debentures and may otherwise deal with and collect obligations owed
to it by the Issuer or its Affiliates and may

                                      A-8
<PAGE>
otherwise deal with the Issuer or its Affiliates with the same rights it would
have if it were not Trustee.

16.  NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES AND STOCKHOLDERS

     No past, present or future director, officer, employee, incorporator, agent
or stockholder or Affiliate of the Issuer, as such, shall have any liability for
any obligations of the Issuer under the Debentures, the Indenture or for any
claim based on, in respect of, or by reason of, such obligations or their
creation. No past, present or future director, officer, employee, incorporator,
agent or stockholder or Affiliate of any of the Guarantors, as such, shall have
any liability for any obligations of the Guarantors under the Debenture
Guarantees, the Indenture or for any claim based on, in respect of, or by reason
of, such obligations or their creation. Each holder of Debentures and Debenture
Guarantees by accepting a Debenture and a Debenture Guarantee waives and
releases all such liabilities. The waiver and release are part of the
consideration for issuance of the Debentures and the Debenture Guarantees. Such
waiver may not be effective to waive liabilities under the federal Debentures
laws and it is the view of the SEC that such a waiver is against public policy.

17.  GOVERNING LAW

     THE DEBENTURES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE
LAWS OF THE STATE OF NEW YORK BUT WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES
OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER
JURISDICTION WOULD BE REQUIRED THEREBY.

18.  AUTHENTICATION

     This Debenture shall not be valid until an authorized signatory of the
Trustee (or an authenticating agent) manually signs the certificate of
authentication on the other side of this Debenture.

19.  ABBREVIATIONS

     Customary abbreviations may be used in the name of a Debentureholder or an
assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the
entireties), JT TEN (=joint tenants with rights of survivorship and not as
tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors
Act).

20.  CUSIP NUMBERS

     Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures the Issuer has caused CUSIP numbers to be
printed on the Debentures. No representation is made as to the accuracy of such
numbers as printed on the

                                      A-9

                               [FORM OF GUARANTEE]

     Each undersigned Guarantor (as defined in the Indenture referred to in the
Debenture upon which this notation is endorsed and each referred to as the
"Guarantor," which term includes any successor person under the Indenture)
hereby unconditionally and irrevocably, jointly and severally, agrees to be
liable as a primary obligor and co-issuer and not merely as a surety (such
obligation to be referred to herein as the "Guarantee"), to each of the Holders
and to the Trustee and their respective successors and assigns that (i) the
principal of and interest on the Debentures will be promptly paid in full when
due, subject to any applicable grace period, whether at maturity, by
acceleration or otherwise, and interest on the overdue principal, if any, and
interest on any interest, if any, to the extent lawful, of the Debentures and
all other obligations of the Issuer to the Holders or the Trustee under the
Indenture or thereunder will be promptly paid in full or performed, all in
accordance with the terms under the Indenture and thereof; and (ii) in case of
any extension of time of payment or renewal of any of the Debentures or of any
such other obligations, the same will be promptly paid in full when due or
performed in accordance with the terms of the extension or renewal, subject to
any applicable grace period, whether at Stated Maturity, by acceleration or
otherwise, subject, however, in the case of clauses (i) and (ii) above, to the
limitations set forth in Section 11.02 of the Indenture. The obligations of the
Guarantors to the Holders of Debentures and to the Trustee pursuant to the

the Guarantee. Each Holder of a Debenture, by accepting the same, (a) agrees to
and shall be bound by such provisions (b) appoints the Trustee attorney-in-fact
of such Holder for such purpose.

     This Guarantee is subordinated to Senior Debt of the Guarantor, as defined
in the Indenture. To the extent provided in the Indenture, Senior Debt of the
Guarantor must be paid before the Guarantee may be paid. The Guarantor agrees,
and each Debentureholder by accepting a Debenture agrees, to the subordination
provisions contained in the Indenture and authorizes the Trustee to give it
effect and appoints the Trustee as attorney-in-fact for such purpose.

     No stockholder, officer, director or incorporator, as such, past, present
or future, of the Guarantor shall have any liability under the Guarantee by
reason of his or its status as such stockholder, officer, director or
incorporator.

     This Guarantee shall not be valid or obligatory for any purpose until the
certificate of authentication on the Debentures upon which this Guarantee is
Debentured shall have been executed by the Trustee under the Indenture by the
manual signature of one of its authorized officers.

Ladies and Gentlemen:

     In connection with our proposed sale of $________ aggregate principal
amount of the Debentures, we confirm that such sale has been effected pursuant

          (2) either (a) at the time the buy order was originated, the
     transferee was outside the United States or we and any person acting on our
     behalf reasonably believed that the transferee was outside the United
     States or (b) the transaction was executed in, on or through the facilities
     of a designated off-shore Debentures market and neither we nor any person
     acting on our behalf knows that the transaction has been pre-arranged with
     a buyer in the United States;

          (3) no directed selling efforts have been made in the United States in
     contravention of the requirements of Rule 903(b) or Rule 904(b) of
     Regulation S, as applicable; and

          (4) the transaction is not part of a plan or scheme to evade the
     registration requirements of the Securities Act.

     In addition, if the sale is made during a restricted period and the
provisions of Rule 903(c)(3) or Rule 904(c)(1) of Regulation S are applicable
thereto, we confirm that such

outlining restrictions upon transfer of such Legended Security. Pursuant to
Section 2.01 of the Indenture dated as of April 21, 2004 (the "Indenture")

Debentures on behalf of) a person outside the United States to whom the
Debentures could be transferred in accordance with Rule 904 of Regulation S
promulgated under the U.S. Securities Act of 1933. Accordingly, you are hereby

          2. GRANT OF LIEN.

          (a) As security for all Obligations, each Grantor hereby grants to the
Agent, for the benefit of the Agent, the Trustee and the Holders, a continuing
security interest in, lien on, assignment of and right of set-off against the
Collateral.

          (b) All of the Obligations shall be secured by all of the Collateral.

          3. PERFECTION AND PROTECTION OF SECURITY INTEREST.

          (a) Each of the Grantors shall, at their own expense, perform all
steps requested by the Agent at any time to perfect, maintain, protect, and
enforce the Agent's Liens, including: (i) executing and filing financing or
continuation statements, and amendments thereof, in form and substance
reasonably satisfactory to the Agent; (ii) placing notations on such Grantor's
books of account to disclose the Agent's security interest; and (iii) taking
such other steps as are deemed necessary or desirable by the Agent to maintain
and protect the Agent's Liens, provided that no Guarantor shall be required to
deliver to the Agent possession of any Instrument comprising an item of
Collateral; provided further that within 30 days after April 30 in each year
beginning with April 30, 2005, the Company shall furnish the Agent an Opinion of
Counsel pursuant to Section 10.02(b)(ii) of the Indenture, whether or not such
Opinion of Counsel is required by the TIA. Each Grantor agrees that a carbon,
photographic, photostatic, or other reproduction of this Security Agreement or
of a financing statement is sufficient as a financing statement.

          (b) Each Grantor hereby irrevocably authorizes the Agent at any time
and from time to time to file in any filing office in any Uniform Commercial
Code jurisdiction any initial financing statements and amendments thereto that
(a) accurately describe the Collateral and (b) contain any other information
required by part 5 of Article 9 of the UCC for the sufficiency or filing office
acceptance of any financing statement or amendment, including whether such
Grantor is an organization, the type of organization and any organization
identification number issued to such Grantor. Each Grantor agrees to furnish any
such information to the Agent promptly upon request. Each Grantor also ratifies
its authorization for the Agent to have filed in any Uniform Commercial Code
jurisdiction any like initial financing statements or amendments thereto if
filed prior to the date hereof.

          (c) From time to time, each Grantor shall, upon the Agent's request,
execute and deliver confirmatory written instruments pledging to the Agent, for
the ratable benefit of the Agent and the Lenders, the Collateral, but any
Grantor's failure to do so shall not affect or limit any security interest or
any other rights of the Agent or any Lender in and to the Collateral with
respect to any Grantor. So long as the Indenture is in effect and until all
Obligations have been fully satisfied, the Agent's Liens shall continue in full
force and effect in all Collateral except for such Collateral as is disposed of
in accordance with the Indenture.

          (d) Terminations Amendments Not Authorized. Each Grantor acknowledges
that it is not authorized to file any financing statement or amendment or
termination statement with respect to any financing statement without the prior
written consent of Agent and agrees

                                       3
<PAGE>
that it will not do so without the prior written consent of Agent, subject to
such Grantor's rights under Section 9.509(d)(2) of the UCC.

          4. LOCATION OF COLLATERAL. Each of the Grantors represents and
warrants to the Agent, the Trustee and the Holders that, as of the date of the
issuance of the Debentures, Schedule A is a correct and complete list of the
location of its chief executive office, the location of its books and records,
the locations of the Collateral, and the locations of all of its other places of
business. Each Grantor covenants and agrees that it will not (i) maintain any
Collateral at any location other than those locations listed for such Grantor on
Schedule A, (ii) otherwise change or add to any of such locations, or (iii)
change the location of its chief executive office from the location identified
in Schedule A, unless it concurrently gives the Agent written notice thereof and
within four months of such change executes any and all financing statements and
other documents that the Agent reasonably requests in connection therewith.

          5. JURISDICTION OF ORGANIZATION. Schedule II hereto identifies each
Grantor's name as of the Closing Date as it appears in official filings in the
state of its incorporation or other organization, the type of entity of such
Grantor (including corporation, partnership, limited partnership or limited
liability company), organizational identification number issued by such
Grantor's state of incorporation or organization or a statement that no such
number has been issued and the jurisdiction in which the such Grantor is
incorporated or organized. Each Grantor has only one state of incorporation or
organization.

          6. TITLE TO, LIENS ON, AND SALE AND USE OF COLLATERAL. Each Grantor
represents and warrants to the Agent, the Trustee and the Holders and agrees
with the Agent, the Trustee and the Holders that: (a) such Grantor has rights in
and the power to transfer rights in all of the Collateral free and clear of all
Liens whatsoever, except for Permitted Liens; and (b) such Grantor will use,
store, and maintain the Collateral with all reasonable care and will use such
Collateral for lawful purposes only.

          7. ACCESS AND EXAMINATION. The Grantors shall permit representatives
and independent contractors of Agent access to their properties and records from
time to time upon the reasonable prior written request of Agent.

          8. EQUIPMENT.

          (a) Each Grantor represents and warrants to the Agent, the Trustee and
the Holders and agrees with the Agent, the Trustee and the Holders that all of
the Equipment owned by such Grantor is and will be used or held for use in such
Grantor's business, and is and will be fit for such purposes. Each Grantor shall
keep and maintain its Equipment in good operating condition and repair (ordinary
wear and tear excepted) and shall make all necessary replacements thereof.

          (b) No Grantor will, without the Agent's prior written consent, alter
or remove any identifying symbol or number on any of such Grantor's Equipment
constituting Collateral.

                                       4
<PAGE>
          (c) Except as permitted under the Indenture, no Grantor shall, without
the Agent's prior written consent, sell, license, lease as a lessor, or
otherwise dispose of any of such Grantor's Equipment.

          9. RIGHT TO CURE. The Agent may, in its discretion, and shall, at the
direction of the Trustee (acting at the direction of the Required Holders), pay
any amount or do any act required of any Grantor hereunder or under the
Indenture or any other Security Document in order to preserve, protect, maintain
or enforce the Obligations, the Collateral or the Agent's Liens therein, and
which any Grantor fails to pay or do, including payment of any judgment against
such Grantor, any insurance premium, any warehouse charge, any finishing or
processing charge, any landlord's or bailee's claim, and any other Lien upon or
with respect to the Collateral; provided, however, that the Agent shall be under
no obligation to take any action which in its sole discretion would subject the
Agent to personal or financial liability. Any payment made or other action taken
by the Agent under this Section 9 shall be without prejudice to any right to
assert an Event of Default hereunder and to proceed thereafter as herein
provided.

          10. THE AGENT'S AND HOLDERS' RIGHTS, DUTIES AND LIABILITIES.

          (a) Each Holder hereby appoints Wilmington Trust Company to act as the
Agent for such Person under this Security Agreement and the other Collateral
Documents. Each Holder hereby irrevocably authorizes the Agent to take such
action on its behalf under the provisions of this Security Agreement and the
other Collateral Documents and to exercise such powers and to perform such
duties hereunder and thereunder as are specifically delegated to or required of
the Agent by the terms hereof and thereof and such other powers as are
reasonably incidental thereto and the Agent shall hold all Collateral, charges
and collections received pursuant to this Security Agreement, for the ratable
benefit of the Holders. The Agent may perform any of its duties hereunder by or
through its agents or employees. As to any matters not expressly provided for by
this Security Agreement (including without limitation, collection of the
Debentures) the Agent shall not be required to exercise any discretion or take
any action, but shall be required to act or to refrain from acting (and shall be
fully protected in so acting or refraining from acting) upon the instructions of
the Trustee or the Required Holders, and such instructions shall be binding;
provided, however, that the Agent shall not be required to take any action which
in the Agent's reasonable discretion exposes it to liability or which is
contrary to this Security Agreement or the other Collateral Documents or
applicable law unless the Agent is furnished with an indemnification reasonably
acceptable to the Agent in its sole discretion with respect thereto and the
Agent shall not be responsible for any misconduct or negligence on the part of
any agents appointed with due care by the Agent. The Agent may utilize the
services of such Persons as the Agent, in its sole discretion, may determine and
all reasonable fees and expenses shall be borne by the Grantors. The Agent shall
have no duties or responsibilities except those expressly set forth in this
Security Agreement and the other Collateral Documents. The Agent shall not be
under any obligation to any Holder to ascertain or to inquire as to the
observance or performance of any of the agreements contained in, or conditions
of, this Security Agreement or any of the other Collateral Documents. The Agent
shall not have by reason of this Security Agreement a fiduciary relationship in
respect of any Holder; and nothing in this Security Agreement, expressed or
implied, is intended to or shall be so construed as to impose

                                       5
<PAGE>
upon the Agent any obligations in respect of this Security Agreement except as
expressly set forth herein.

          (b) The Grantors assume jointly and severally all responsibility and
liability arising from or relating to the use, sale, license or other
disposition of the Collateral. The Obligations shall not be affected by any
failure of the Agent, the Trustee or any Holder to take any steps to perfect the
Agent's Liens or to collect or realize upon the Collateral, nor shall loss of or
damage to the Collateral release any Grantor from any of the Obligations.
Following the occurrence and during the continuation of an Event of Default, the
Agent may (but shall not be required to), and at the direction of the Required
Holders shall, without notice to or consent from any Grantor, sue upon or
otherwise collect, extend the time for payment of, modify or amend the terms of,
compromise or settle for cash, credit, or otherwise upon any terms, grant other
indulgences, extensions, renewals, compositions, or releases, and take or omit
to take any other action with respect to the Collateral, any security therefor,
any agreement relating thereto, any insurance applicable thereto, or any Person
liable directly or indirectly in connection with any of the foregoing, without
discharging or otherwise affecting the liability of any Grantor for the
Obligations or under the Indenture or any other agreement now or hereafter
existing between the Agent and/or the Trustee or any Holder and any Grantor.

          (c) It is expressly agreed by each Grantor that, anything herein to
the contrary notwithstanding, each Grantor shall remain liable under each of its
contracts and each of its licenses to observe and perform all the conditions and
obligations to be observed and performed by it thereunder. None of the Agent,
the Trustee nor any Holder shall have any obligation or liability under any
contract or license by reason of or arising out of this Security Agreement or
the granting herein of a Lien thereon or the receipt by Agent, the Trustee or
any Holder of any payment relating to any contract or license pursuant hereto.
None of the Agent, the Trustee nor any Holder shall be required or obligated in
any manner to perform or fulfill any of the obligations of any Grantor under or
pursuant to any contract or license, or to make any payment, or to make any
inquiry as to the nature or the sufficiency of any payment received by it or the
sufficiency of any performance by any party under any contract or license, or to
present or file any claims, or to take any action to collect or enforce any
performance or the payment of any amounts which may have been assigned to it or
to which it may be entitled at any time or times.

          (d) Neither the Agent nor any of the Agent's officers, directors,
employees, agents, attorneys-in-fact or Affiliates shall be (1) liable for any
action taken or omitted to be taken by it or such Person under or in connection
with this Security Agreement or the Collateral Documents or any Collateral
(except for its or such Person's own negligence or willful misconduct), or (2)
responsible in any manner to any of the Holders for any recitals, statements,
representations or warranties made by the Grantors, any officer thereof or any
other Person contained in, or made or deemed made in connection with, any
Collateral Document or in any certificate, report, statement or other document
referred to or provided for in, or received by the Agent under or in connection
with this Security Agreement or the Collateral Documents, or for the due
execution, legality, value, validity, effectiveness, genuineness, enforceability
or sufficiency of this Security Agreement or the Collateral Documents or any
other document or instrument furnished pursuant thereto or of any of the
Collateral or for any failure of any Grantor to perform its obligations under
such documents.

                                       6
<PAGE>
          (e) The Agent shall be entitled to conclusively rely, and shall be
fully protected and shall incur no liability in acting and relying, upon any
writing, resolution, notice, consent, certificate, affidavit, letter, cablegram,
telegram, telecopy, statement, order or other document reasonably believed by it
to be genuine and correct and to have been signed, sent or made by the proper
Person or Persons and upon advice of its legal counsel (which shall not also be
counsel to any Grantor), written advice of legal counsel to any Grantor that is
required pursuant to the Indenture, or upon advice of independent accountants
and other experts selected by the Agent.

          11. COST AND EXPENSES; INDEMNIFICATION.

          (a) The Grantors agree to indemnify the Agent in its capacity as such,
against, and hold the Agent harmless from, any and all liabilities, obligations,
losses, claims, damages, penalties, actions, judgments, suits, costs, expenses
or disbursements of any kind or nature whatsoever, which may be imposed on,
incurred by, or asserted against the Agent, in any way relating to or arising
out of this Security Agreement or the Collateral Documents or the transactions
contemplated hereby or thereby or any action taken or omitted by the Agent in
connection with any of the foregoing; provided that no Grantor shall be liable
to the Agent for any portion of such liabilities, obligations, losses, claims,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
to the extent they are found by a final decision of a court of competent
jurisdiction to have resulted from the Agent's negligence or willful misconduct.
The agreements in this Section 11 shall survive the payment of the Obligations.

          (b) The Grantors agree to pay to the Agent, for its benefit, on
demand, all reasonable costs and expenses that Agent pays or incurs in
connection with the negotiation, preparation, administration, enforcement, and
termination of this Security Agreement or any of the other Collateral Documents,
including: (1) all reasonable fees, expenses and disbursements of any law firm
or other counsel engaged by the Agent; (2) costs and expenses (including
reasonable attorneys' and paralegals' fees and disbursements) for any amendment,
supplement, waiver, consent, or subsequent closing in connection with the
Collateral Documents and the transactions contemplated thereby; (3) costs and
expenses of lien searches; (4) taxes, fees and other charges for filing
financing statements and continuations, and other actions to perfect, protect,
and continue the Agent's Liens (including costs and expenses paid or incurred by
the Agent in connection with the consummation of this Security Agreement); (5)
sums paid or incurred to pay any amount or take any action required of the
Grantors under the Collateral Documents that the Grantors fail to pay or take;
and (6) costs and expenses of preserving and protecting the Collateral. The
foregoing shall not be construed to limit any other directly contrary provisions
of the Collateral Documents regarding costs and expenses to be paid by any
Grantor.

          (c) In any suit, proceeding or action brought by Agent, the Trustee or
any Holder to enforce its rights with respect to any Collateral for any sum
owing with respect thereto or to enforce any rights or claims with respect
thereto, each Grantor will jointly and severally save, indemnify and keep Agent,
the Trustee and Holders harmless from and against all expense (including
reasonable attorneys' fees and expenses), loss or damage suffered by reason of
any defense, setoff, counterclaim, recoupment or reduction of liability
whatsoever of the Account Debtor or other Person obligated on the Collateral,
arising out of a breach by any Grantor of any

                                       7
<PAGE>
obligation thereunder or arising out of any other agreement, indebtedness or
liability at any time owing to, or in favor of, such obligor or its successors
from such Grantor, except in the case of Agent, the Trustee or any Holder, to
the extent such expense, loss, or damage is determined by a court of competent
jurisdiction in a final nonappealable judgment to have resulted primarily from
the gross negligence or willful misconduct of Agent, the Trustee or such Holder
as finally determined by a court of competent jurisdiction. All such obligations
of the Grantors shall be and remain enforceable against and only against each
Grantor and shall not be enforceable against Agent, the Trustee or any Holder.

          12. LIMITATION ON LIENS ON COLLATERAL. Each Grantor will not create,
permit or suffer to exist, and will defend the Collateral against, and take such
other action as is necessary to remove, any Lien on the Collateral except
Permitted Liens, and will defend the right, title and interest of Agent and the
Holders in and to any of either of the Grantor's rights under the Collateral
against the claims and demands of all Persons whomsoever.

          13. NOTICE REGARDING COLLATERAL. Each Grantor will advise Agent
promptly, in reasonable detail, (i) of any Lien (other than Permitted Liens) or
claim made or asserted against any of the Collateral, and (ii) of the occurrence
of any other event which could reasonably be expected to have a Material Adverse
Effect.

          14. REMEDIES; RIGHTS UPON DEFAULT.

          (a) In addition to all other rights and remedies granted to it under
this Security Agreement, the Indenture, the other Collateral Documents and under
any other instrument or agreement securing, evidencing or relating to any of the
Obligations, if any Event of Default shall have occurred and be continuing,
Agent may exercise all rights and remedies of a secured party under the UCC.
Without limiting the generality of the foregoing, each Grantor expressly agrees
that in any such event Agent, without demand of performance or other demand,
advertisement or notice of any kind (except the notice specified below of time
and place of public or private sale) to or upon such Grantor or any other Person
(all and each of which demands, advertisements and notices are hereby expressly
waived to the maximum extent permitted by the UCC and other applicable law), may
forthwith enter upon the premises of such Grantor where any Collateral is
located through self-help, without judicial process, without first obtaining a
final judgment or giving such Grantor or any other Person notice and opportunity
for a hearing on Agent's claim or action and may collect, receive, assemble,
process, appropriate and realize upon the Collateral, or any part thereof, and
may forthwith sell, lease, license, assign, give an option or options to
purchase, or sell or otherwise dispose of and deliver said Collateral (or
contract to do so), or any part thereof, in one or more parcels at a public or
private sale or sales, at any exchange at such prices as it may deem acceptable,
for cash or on credit or for future delivery without assumption of any credit
risk. Agent, the Trustee or any Holder shall have the right upon any such public
sale or sales and, to the extent permitted by law, upon any such private sale or
sales, to purchase for the benefit of Agent, the Trustee and Holders, the whole
or any part of said Collateral so sold, free of any right or equity of
redemption, which equity of redemption each Grantor hereby releases. Such sales
may be adjourned and continued from time to time with or without notice. Agent
shall have the right to conduct such sales on the Grantors' premises or
elsewhere and shall have the right to use the Grantors' premises without charge
for such time or times as Agent deems necessary or advisable.

                                       8
<PAGE>
          (b) Each Grantor further agrees, at Agent's request, to assemble the
Collateral and make it available to Agent at a place or places designated by
Agent which are reasonably convenient to Agent and Grantor, whether at such
Grantor's premises or elsewhere. Until Agent is able to effect a sale, lease, or
other disposition of Collateral, Agent shall have the right to hold or use
Collateral, or any part thereof, to the extent that it deems appropriate for the
purpose of preserving Collateral or its value or for any other purpose deemed
appropriate by Agent. Agent shall have no obligation to any Grantor to maintain
or preserve the rights of such Grantor as against third parties with respect to
Collateral while Collateral is in the possession of Agent. Agent may, if it so
elects, seek the appointment of a receiver or keeper to take possession of
Collateral and to enforce any of Agent's remedies (for the benefit of Agent, the
Trustee and Holders), with respect to such appointment without prior notice or
hearing as to such appointment. Agent shall apply the net proceeds of any such
collection, recovery, receipt, appropriation, realization or sale to the
Obligations as provided herein and in the Indenture, and only after so paying
over such net proceeds, and after the payment by Agent of any other amount
required by any provision of law, need Agent account for the surplus, if any, to
the applicable Grantor. To the maximum extent permitted by applicable law, each
Grantor waives all claims, damages, and demands against Agent, the Trustee or
any Holder arising out of the repossession, retention or sale of the Collateral
except such as determined by a court of competent jurisdiction in a final
nonappealable judgment to have resulted primarily from the gross negligence or
willful misconduct of Agent, the Trustee or such Holder as finally determined by
a court of competent jurisdiction. Each Grantor agrees that ten (10) days prior
written notice by Agent of the time and place of any public sale or of the time
after which a private sale may take place is reasonable notification of such
matters. Each Grantor shall remain liable for any deficiency if the proceeds of
any sale or disposition of the Collateral are insufficient to pay all
Obligations, including any reasonable attorneys' fees or other out-of-pocket
expenses actually incurred by Agent, the Trustee or any Holder to collect such
deficiency.

          (c) Except as otherwise specifically provided herein, each Grantor
hereby waives presentment, demand, protest or any notice (to the maximum extent
permitted by applicable law) of any kind in connection with this Security
Agreement or any Collateral.

          (d) To the extent that applicable law imposes duties on the Agent to
exercise remedies in a commercially reasonable manner, each Grantor acknowledges
and agrees that it is not commercially unreasonable for the Agent (a) to fail to
incur expenses reasonably deemed significant by the Agent to prepare Collateral
for disposition, (b) to fail to obtain third party consents for access to
Collateral to be disposed of, or to obtain or, if not required by other law, to
fail to obtain governmental or third party consents for the collection or
disposition of Collateral to be collected or disposed of, (c) to fail to
exercise collection remedies against Persons obligated on Collateral or to
remove Liens on or any adverse claims against Collateral, (d) to exercise
collection remedies against Persons obligated on Collateral directly or through
the use of collection agencies and other collection specialists, (e) to
advertise dispositions of Collateral through publications or media of general
circulation, whether or not the Collateral is of a specialized nature, (f) to
contact other Persons, whether or not in the same business as such Grantor, for
expressions of interest in acquiring all or any portion of such Collateral, (g)
to hire one or more professional auctioneers to assist in the disposition of
Collateral, whether or not the Collateral is of a specialized nature, (h) to
dispose of Collateral by utilizing Internet sites that provide for the auction
of assets of the types included in the Collateral or that have the

                                       9
<PAGE>
reasonable capacity of doing so, or that match buyers and sellers of assets, (i)
to dispose of assets in wholesale rather than retail markets, (j) to disclaim
disposition warranties, such as title, possession or quiet enjoyment, (k) to
purchase insurance or credit enhancements to insure the Agent against risks of
loss, collection or disposition of Collateral or to provide to the Agent a
guaranteed return from the collection or disposition of Collateral, or (l) to
the extent deemed appropriate by the Agent, to obtain the services of other
brokers, investment bankers, consultants and other professionals to assist the
Agent in the collection or disposition of any of the Collateral. Each Grantor
acknowledges that the purpose of this Section 14(d) is to provide non-exhaustive
indications of what actions or omissions by the Agent would not be commercially
unreasonable in the Agent's exercise of remedies against the Collateral and that
other actions or omissions by the Agent shall not be deemed commercially
unreasonable solely on account of not being indicated in this Section 14(d).
Without limitation upon the foregoing, nothing contained in this Section 14(d)
shall be construed to grant any rights to any Grantor or to impose any duties on
Agent that would not have been granted or imposed by this Security Agreement or
by applicable law in the absence of this Section 14(d).

          15. LIMITATION ON AGENT'S AND HOLDERS' DUTY IN RESPECT OF COLLATERAL.
Agent, the Trustee and each Holder shall use reasonable care with respect to the
Collateral in its possession or under its control. None of Agent, the Trustee or
any Holder shall have any other duty as to any Collateral in its possession or
control or in the possession or control of any agent or nominee of Agent, the
Trustee or such Holder, or any income thereon or as to the preservation of
rights against prior parties or any other rights pertaining thereto.

          16. MISCELLANEOUS.

          (a) REINSTATEMENT. This Security Agreement shall remain in full force
and effect and continue to be effective should any petition be filed by or
against any Grantor for liquidation or reorganization, should any Grantor become
insolvent or make an assignment for the benefit of any creditor or creditors or
should a receiver or trustee be appointed for all or any significant part of any
Grantor's assets, and shall continue to be effective or be reinstated, as the
case may be, if at any time payment and performance of the Obligations, or any
part thereof, is, pursuant to applicable law, rescinded or reduced in amount, or
must otherwise be restored or returned by any obligee of the Obligations,
whether as a "voidable preference," "fraudulent conveyance," or otherwise, all
as though such payment or performance had not been made. In the event that any
payment, or any part thereof, is rescinded, reduced, restored or returned, the
Obligations shall be reinstated and deemed reduced only by such amount paid and
not so rescinded, reduced, restored or returned.

          (b) NOTICES. Except as otherwise provided herein, whenever it is
provided herein that any notice, demand, request, consent, approval, declaration
or other communication shall or may be given to or served upon any of the
parties by any other party, or whenever any of the parties desires to give and
serve upon any other party any communication with respect to this Security
Agreement, each such notice, demand, request, consent, approval, declaration or
other communication shall be in writing and shall be given in the manner, and
deemed received, as provided for in the Indenture; provided, however that notice
to the Agent shall be delivered to the following address or such other address
as notified by the Agent from time to time:

          (c) SEVERABILITY. Whenever possible, each provision of this Security
Agreement shall be interpreted in a manner as to be effective and valid under
applicable law, but if any provision of this Security Agreement shall be
prohibited by or invalid under applicable law, such provision shall be
ineffective to the extent of such prohibition or invalidity without invalidating
the remainder of such provision or the remaining provisions of this Security
Agreement. This Security Agreement is to be read, construed and applied together
with the Indenture and the other Collateral Documents which, taken together, set
forth the complete understanding and agreement of Agent, the Trustee, the
Holders and the Grantors with respect to the matters referred to herein and
therein.

          (d) NO WAIVER; CUMULATIVE REMEDIES. Neither Agent, the Trustee nor any
Holder shall by any act, delay, omission or otherwise be deemed to have waived
any of its rights or remedies hereunder, and no waiver shall be valid unless in
writing, signed by Agent and then only to the extent therein set forth. A waiver
by Agent of any right or remedy hereunder on any one occasion shall not be
construed as a bar to any right or remedy which Agent would otherwise have had
on any future occasion. No failure to exercise nor any delay in exercising on
the part of Agent, the Trustee or any Holder, any right, power or privilege
hereunder, shall operate as a waiver thereof, nor shall any single or partial
exercise of any right, power or privilege hereunder preclude any other or future
exercise thereof or the exercise of any other right, power or privilege. The
rights and remedies hereunder provided are cumulative and may be exercised
singly or concurrently, and are not exclusive of any rights and remedies
provided by law. None of the terms or provisions of this Security Agreement may
be waived, altered, modified or amended except by an instrument in writing, duly
executed by Agent and the Grantors.

          (e) LIMITATION BY LAW. All rights, remedies and powers provided in
this Security Agreement may be exercised only to the extent that the exercise
thereof does not violate any applicable provision of law, and all the provisions
of this Security Agreement are intended to be subject to all applicable
mandatory provisions of law that may be controlling and to be limited to the
extent necessary so that they shall not render this Security Agreement invalid,
unenforceable, in whole or in part, or not entitled to be recorded, registered
or filed under the provisions of any applicable law.

          (f) TERMINATION OF THIS SECURITY AGREEMENT. Subject to Section 16(a)
hereof, this Security Agreement shall terminate upon the payment in full of all
other Obligations (other than indemnification Obligations as to which no claim
has been asserted).

          (g) SUCCESSORS AND ASSIGNS. This Security Agreement and all
obligations of the Grantors hereunder shall be binding upon the successors and
assigns of the Grantors (including any debtor-in-possession on behalf of any
Grantor) and shall, together with the rights

                                       11
<PAGE>
and remedies of Agent, for the benefit of Agent, the Trustee and Holders,
hereunder, inure to the benefit of Agent, the Trustee and Holders, all future
holders of any instrument evidencing any of the Obligations and their respective
successors and assigns. No sales of participations, other sales, assignments,
transfers or other dispositions of any agreement governing or instrument
evidencing the Obligations or any portion thereof or interest therein shall in
any manner affect the Lien granted to Agent, for the benefit of Agent, the
Trustee and Holders, hereunder. No Grantor may assign, sell, hypothecate or
otherwise transfer any interest in or obligation under this Security Agreement.

          (h) COUNTERPARTS. This Security Agreement may be authenticated in any
number of separate counterparts, each of which shall collectively and separately
constitute one and the same agreement. This Security Agreement may be
authenticated by manual signature, facsimile or, if approved in writing by
Agent, electronic means, all of which shall be equally valid.

          (i) GOVERNING LAW. EXCEPT AS OTHERWISE EXPRESSLY PROVIDED IN ANY OF
THE LOAN DOCUMENTS, IN ALL RESPECTS, INCLUDING ALL MATTERS OF CONSTRUCTION,
VALIDITY AND PERFORMANCE, THIS SECURITY AGREEMENT AND THE OBLIGATIONS ARISING
HEREUNDER SHALL BE GOVERNED BY, AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH,
THE LAWS OF THE STATE OF NEW YORK AND ANY APPLICABLE LAWS OF THE UNITED STATES
OF AMERICA. EACH GRANTOR HEREBY CONSENTS AND AGREES THAT THE STATE OR FEDERAL
COURTS LOCATED IN DALLAS COUNTY, CITY OF DALLAS, SHALL HAVE EXCLUSIVE
JURISDICTION TO HEAR AND DETERMINE ANY CLAIMS OR DISPUTES BETWEEN ANY GRANTOR,
AGENT, THE TRUSTEE AND HOLDERS PERTAINING TO THIS SECURITY AGREEMENT OR ANY OF
THE OTHER SECURITY DOCUMENTS OR TO ANY MATTER ARISING OUT OF OR RELATING TO THIS
SECURITY AGREEMENT OR ANY OF THE OTHER SECURITY DOCUMENTS; PROVIDED, THAT AGENT,
THE TRUSTEE, HOLDERS AND THE GRANTORS ACKNOWLEDGE THAT ANY APPEALS FROM THOSE
COURTS MAY HAVE TO BE HEARD BY A COURT LOCATED OUTSIDE OF DALLAS COUNTY, CITY OF
DALLAS, AND, PROVIDED, FURTHER, NOTHING IN THIS SECURITY AGREEMENT SHALL BE
DEEMED OR OPERATE TO PRECLUDE AGENT FROM BRINGING SUIT OR TAKING OTHER LEGAL
ACTION IN ANY OTHER JURISDICTION TO REALIZE ON THE COLLATERAL OR ANY OTHER
SECURITY FOR THE OBLIGATIONS, OR TO ENFORCE A JUDGMENT OR OTHER COURT ORDER IN
FAVOR OF AGENT. EACH GRANTOR EXPRESSLY SUBMITS AND CONSENTS IN ADVANCE TO SUCH
JURISDICTION IN ANY ACTION OR SUIT COMMENCED IN ANY SUCH COURT, AND EACH GRANTOR
HEREBY WAIVES ANY OBJECTION WHICH IT MAY HAVE BASED UPON LACK OF PERSONAL
JURISDICTION, IMPROPER VENUE OR FORUM NON CONVENIENS AND HEREBY CONSENTS TO THE
GRANTING OF SUCH LEGAL OR EQUITABLE RELIEF AS IS DEEMED APPROPRIATE BY SUCH
COURT. EACH GRANTOR HEREBY WAIVES PERSONAL SERVICE OF THE SUMMONS, COMPLAINT AND
OTHER PROCESS ISSUED IN ANY SUCH ACTION OR SUIT AND AGREES THAT SERVICE OF SUCH
SUMMONS, COMPLAINTS AND OTHER PROCESS MAY BE MADE BY REGISTERED OR CERTIFIED
MAIL ADDRESSED TO SUCH GRANTOR AT THE ADDRESS SET FORTH IN SECTION 14.02 OF THE
INDENTURE (SUCH NOTICE TO THE PARENT

                                       12
<PAGE>
BEING DELIVERED TO THE PARENT IN CARE OF THE COMPANY AT THE COMPANY'S ADDRESS
SET FORTH IN SECTION 14.02 OF THE INDENTURE) AND THAT SERVICE SO MADE SHALL BE
DEEMED COMPLETED UPON THE EARLIER OF ACTUAL RECEIPT THEREOF OR THREE (3) DAYS
AFTER DEPOSIT IN THE U.S. MAILS, PROPER POSTAGE PREPAID.

          (j) WAIVER OF JURY TRIAL. BECAUSE DISPUTES ARISING IN CONNECTION WITH
COMPLEX FINANCIAL TRANSACTIONS ARE MOST QUICKLY AND ECONOMICALLY RESOLVED BY AN
EXPERIENCED AND EXPERT PERSON AND THE PARTIES WISH APPLICABLE STATE AND FEDERAL
LAWS TO APPLY (RATHER THAN ARBITRATION RULES), THE PARTIES DESIRE THAT DISPUTES
ARISING HEREUNDER OR RELATING HERETO BE RESOLVED BY A JUDGE APPLYING SUCH
APPLICABLE LAWS. THEREFORE, TO ACHIEVE THE BEST COMBINATION OF THE BENEFITS OF
THE JUDICIAL SYSTEM AND OF ARBITRATION, THE PARTIES HERETO WAIVE ALL RIGHT TO
TRIAL BY JURY IN ANY ACTION, SUIT OR PROCEEDING BROUGHT TO RESOLVE ANY DISPUTE,
WHETHER SOUNDING IN CONTRACT, TORT, OR OTHERWISE, AMONG AGENT, LENDERS, AND
GRANTORS ARISING OUT OF, CONNECTED WITH, RELATED TO, OR INCIDENTAL TO THE
RELATIONSHIP ESTABLISHED IN CONNECTION WITH, THIS SECURITY AGREEMENT OR ANY OF
THE OTHER SECURITY DOCUMENTS OR THE TRANSACTIONS RELATED HERETO OR THERETO.

          (k) SECTION TITLES. The Section titles contained in this Security
Agreement are and shall be without substantive meaning or content of any kind
whatsoever and are not a part of the agreement between the parties hereto.

          (l) NO STRICT CONSTRUCTION. The parties hereto have participated
jointly in the negotiation and drafting of this Security Agreement. In the event
an ambiguity or question of intent or interpretation arises, this Security
Agreement shall be construed as if drafted jointly by the parties hereto and no
presumption or burden of proof shall arise favoring or disfavoring any party by
virtue of the authorship of any provisions of this Security Agreement.

          (m) ADVICE OF COUNSEL. Each of the parties represents to each other
party hereto that it has discussed this Security Agreement and, specifically,
the provisions of Section 17(i) and Section 17(j), with its counsel.

          (n) BENEFIT OF HOLDERS. All Liens granted or contemplated hereby shall
be for the benefit of Agent, the Trustee and Holders, and all proceeds or
payments realized from Collateral in accordance herewith shall be applied to the
Obligations in accordance with the terms of the Indenture.

          (o) INCORPORATION BY REFERENCE. All of the rights, protections and
privileges granted to the Trustee under the Indenture are incorporated by
reference herein and shall inure to the benefit of the Agent herein.

                                       13
<PAGE>
          IN WITNESS WHEREOF, each of the parties hereto has caused this
Security Agreement to be executed and delivered by its duly authorized officer
as of the date first set forth above.
