                                   AGREEMENT

     This Agreement is entered into this 8th day of May, 2002 by and between
Abaxis, Inc. ("Abaxis") and S.A. Scientific, Inc. ("SAS").

                                    RECITALS

     WHEREAS, SAS and Abaxis have previously entered into an Agreement styled
"Terms of Agreement Between Abaxis, Inc. and SA Scientific," in November, 2001,
and

     WHEREAS, Idexx Laboratories, Inc. ("Idexx") has instituted a lawsuit
against Abaxis and SAS in the United States District Court for the District of
Maine, Civil Number 02-69-PH ("the Litigation") in which Idexx has alleged
infringement by Abaxis and SAS of U.S. Patents Nos. 4,939,096 and 4,965,187
("the Idexx Patents In Suit") by reason of the manufacture and sale of certain
canine heartworm antigen tests ("the Accused Products"); and

     WHEREAS, SAS sells the Accused Products to Abaxis, who then re-sells them;
and

     WHEREAS, Abaxis and SAS have previously retained separate and independent
counsel to represent them in the Litigation; and

     WHEREAS, Abaxis and SAS recognize that there could be potential conflicts
of interest arising out of joint representation in connection with the
Litigation or their relationship to date but that neither has any intent to sue
the other and indeed desire to form a lasting business relationship which may
include SAS manufacturing other products in the future for Abaxis; and

     WHEREAS, Abaxis and SAS wish to minimize the cost of the Litigation by
jointly retaining outside counsel to represent them in the Litigation and to
resolve conflicts between them as they relate to the Litigation;

     NOW, THEREFORE, in consideration of the mutual agreements and
understandings set forth herein, SAS and Abaxis agree as follows:

     1.   Release of Known Existing Claims   SAS and Abaxis, and each of them,
and their officers, directors, successors, agents and assigns and those in
privity with them, hereby release, acquit and discharge each other and their
affiliates, attorneys, agents, assigns and those in privity with them of and
from any and all presently existing and known claims, demands and/or causes of
action growing out of their relationship with each other, including but not
limited to their contractual relationship arising out of the November, 2001
Agreement. This release does not release any accounts receivable or amount owing
for goods sold by the parties to each other prior to the date of this Agreement.

     2.   Covenant Not to Sue On Claims Arising Out of the Patents In Suit
SAS and Abaxis agree that if Idexx is successful in pursuing claims arising out
of the Patents in Suit in the Litigation, and such result is reduced to a final
judgment from which not appeal will lie, each will pay one half of whatever
judgment may be entered in the Litigation insofar as it relates to damages for
infringement of the Patents in Suit. The parties further agree that neither will
assert any claim against the other for indemnity or contribution, so long as
the other party pays its one half share of any such judgment. In the event one
or the other of the parties does not pay its one

                                       1
<PAGE>
half share of any such damage award and the other party is required to pay all
or any part of the other party's half of the judgment, the party paying more
than one half of the total judgment shall have a claim against the other for the
amount paid in excess of one half of the judgment, and shall also be entitled to
attorneys fees and costs incurred in collecting said amount from the other
party. If claims other than those related to the Patents In suit are asserted by
Idexx in the Litigation, the parties shall consult in good faith as to whether
this Agreement shall be amended to include such disputes but neither party shall
be required to amend this Agreement for such purpose. The provisions of this
paragraph shall apply only to judgments arising out of liability for
infringement of the Patents In Suit. The provisions of this paragraph shall not
apply to damages for willful infringement or punitive damages.

        3. Joint Representation   Effective May 20, 2002, Abaxis and SAS agree
that they shall hereafter jointly direct who shall act as counsel of record for
Abaxis and SAS. After May 20, 2002, unless and until otherwise jointly directed
by Abaxis and SAS, the law firm of Workman, Nydegger & Seeley (Brent Lorimer,
Tom Vuksinick, and David Seeley) of Salt Lake City, Utah are jointly authorized
and requested by SAS and Abaxis to become lead counsel for both parties in said
Lawsuit. Until May 20, 2002, WNS will continue to separately represent Abaxis
and will not represent SAS, and Langley & Banack will continue to separately
represent SAS and will not represent Abaxis.

        4. Payment for Joint Representation after the Effective Date   Beginning
May 20, 2002, the parties agree to split the cost of joint representation and
related costs in the Litigation (including, but not limited to, expert witness
fees), on a 50-50 basis. WNS and LB shall submit invoices for joint services to
both Abaxis and SAS on a monthly basis, with each to pay one half of the total
invoice. In the event SAS or Abaxis fails to pay its one half of invoices for
joint work submitted by WNS or LB within 45 days of submission of such invoices,
the entire amount of the invoice shall become the joint and several obligation
of both SAS and Abaxis, and the affected law firm shall be entitled to collect
the entire amount from either party. The party paying more than its one half
share of such invoices shall have the right to bring an action against the other
party for collection of the amount paid in excess of its one half share, as well
as the attorneys' fees and costs associated with such collection efforts.
Failure by either party to pay its one half share within 45 days of submission
for two consecutive billing cycles shall entitle the affected law firm to
terminate representation of that party. Such party consents in advance to
withdrawal from representation by the affected law firm. Neither party shall be
required to pay for services rendered to the other that are not part of the
joint effort to defend the Litigation.

        5. Payment for Services Prior to the Effective Date   Within 90 days
from the date of this Agreement, SAS and Abaxis shall each present to each other
copies of the invoices from their respective counsel representing the time and
costs incurred in the defense of the Litigation prior to the Effective Date. SAS
and Abaxis will, within 30 days of the submission of such invoices, review the
same and to the extent one party incurred costs or attorneys' fees which were
beneficial to both parties, SAS and Abaxis will adjust their account between
them so as to result in a 50-50 bearing of expenses associated with the defense
of the Litigation. This Agreement, however, shall have no affect on the
obligation of the party who originally retained counsel prior to the Effective
Date to pay for services rendered and costs incurred prior to the Effective
Date.

        6. Actual and Potential Conflicts of Interest   In the event that actual
or potential conflicts of interest arise which would render it inappropriate for
one law firm to jointly represent both parties, and the conflict is waivable or
could be resolved by withdrawing from representation of one of the parties, SAS
agrees that WNS may continue to separately represent Abaxis, and Abaxis agrees
that LB may continue to separately represent SAS. SAS and Abaxis hereby
acknowledge that the potential and actual conflicts arising out of joint
representation have been explained to them, that they understand such conflicts,
and that to the extent such conflicts are waivable, they are waived, at least
insofar as necessary to allow WNS to continue to separately represent Abaxis,
and LB to continue to separately represent SAS vis-a-vis Idexx in the
Litigation.

        7. Termination of Joint Representation   Nothing herein shall be
construed to prevent any party hereto, WNS or LB from withdrawing from the
joint representation contemplated by this Agreement, upon the giving of written
notice to the other and to joint counsel. The withdrawing party shall still
remain responsible to pay one half of the fees and costs incurred prior to the
date of notice. If WNS or LB withdraws from joint representation, SAS agrees
that WNS may, in its sole discretion, continue to represent Abaxis vis-a-vis
Idexx. Similarly, Abaxis agrees that in such event LB may, in its sole
discretion, continue to represent SAS vis-a-vis Idexx.

        8. Arbitration of Disputes   Any dispute that may hereafter arise
relating to the meaning, scope, or enforcement of this Agreement shall be
subject to mediation by a mediator jointly selected by the parties. If
mediation is not successful, any disputes arising hereunder shall be subject to
binding arbitration by a single arbitrator jointly selected by the parties.
Such arbitration shall not be undertaken under the more formal and more
expensive guidelines of the American Arbitration Association. If the parties
are unable to agree to an arbitrator, such arbitrator shall be selected by
Brent Lorimer and Peter Kilpatrick. Such arbitration shall be conducted at a
neutral location and shall be conducted as expeditiously as possible, with the
costs of arbitration to be split equally between the parties. The arbitrator
shall at the earliest convenient time set a meeting to discuss the logistics of
the arbitration and shall render a decision not more than 30 days following the
hearing of the matter.

        9. Benefit of Counsel   Each party acknowledges that it has had the
benefit of counsel in reviewing and approving this Agreement, and that neither
party shall be construed as the sole draftsman of the Agreement.

        10. Prior November, 2001 Agreement   Notwithstanding the foregoing,
unless clearly stated to the contrary and until a new business agreement is
executed, nothing in this Agreement shall supercede the provisions of the
November 2001 Agreement.

        11. Binding Effect   This Agreement shall be binding upon and inure to
the benefit of the parties hereto.

        12. Waiver   The waiver, express or implied, by either party of any
right hereunder or of any future to perform or breach hereof by the other party
shall not constitute or be deemed a waiver of any other right hereunder or of
any other failure to perform or breach hereof by the other party, whether of a
similar or dissimilar nature.

                                       3

        13. Severability   If any part of this Agreement shall be determined to
be illegal, invalid or unenforceable, that part shall be severed from the
Agreement and the remaining parts shall be valid and enforceable, so long as the
remaining parts continue to fulfill the original intent of the parties.

        14. Consideration   The parties hereto acknowledge that this Agreement
is supported by adequate consideration and that such consideration has been
received.

        15. Counterparts   This Agreement may be executed in counterparts, each
of which shall be considered an original.

Dated and signed this 8th day of May, 2002.

        REGULATION S UNDER THE SECURITIES ACT, (2) AGREES THAT IT WILL NOT,

        RESTRICTIONS ON TRANSFER OF THIS NOTE (THE FORM OF WHICH LETTER CAN BE
        OBTAINED FROM THE TRUSTEE), AND, IF SUCH TRANSFER IS IN RESPECT OF AN
        AGGREGATE PRINCIPAL AMOUNT OF NOTES OF LESS THAN $100,000, AN OPINION OF
        COUNSEL ACCEPTABLE TO PACIFICARE HEALTH SYSTEMS, INC. THAT SUCH TRANSFER

        SET FORTH ON THE REVERSE HEREOF RELATING TO THE MANNER OF SUCH TRANSFER

        INFORMATION AS EITHER OF THEM MAY REASONABLY REQUIRE TO CONFIRM THAT
        SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A
        TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE
        SECURITIES ACT. AS USED HEREIN, THE TERMS "OFFSHORE TRANSACTION",
        "UNITED STATES" AND "U.S. PERSON" HAVE THE MEANINGS GIVEN TO THEM BY
        REGULATION S UNDER THE SECURITIES ACT. THE INDENTURE CONTAINS PROVISIONS
        REQUIRING THE TRUSTEE TO REFUSE TO REGISTER ANY TRANSFER OF THIS NOTE IN
        VIOLATION OF THE FOREGOING RESTRICTION.

               Each Global Note, whether or not an Exchange Note, shall also
bear the following legend on the face thereof:

                                       27
<PAGE>

        UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF
        THE DEPOSITORY TRUST COMPANY, TO PACIFICARE HEALTH SYSTEMS, INC. OR ITS
        AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY
        CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH
        OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE
        DEPOSITORY TRUST COMPANY (AND ANY PAYMENT HEREON IS MADE TO CEDE & CO.
        OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE
        OF THE DEPOSITORY TRUST COMPANY), ANY TRANSFER, PLEDGE OR OTHER USE
        HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL SINCE THE
        REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.

        TRANSFERS OF THIS GLOBAL NOTE SHALL BE LIMITED TO TRANSFERS IN WHOLE,
        BUT NOT IN PART, TO NOMINEES OF CEDE & CO. OR TO A SUCCESSOR THEREOF OR
        SUCH SUCCESSOR'S NOMINEE AND TRANSFERS OF PORTIONS OF THIS GLOBAL NOTE
        SHALL BE LIMITED TO TRANSFERS MADE IN ACCORDANCE WITH THE RESTRICTIONS
        SET FORTH IN SECTION 2.08 OF THE INDENTURE.

               SECTION 2.03. Execution, Authentication and Denominations.
Subject to Article Four and applicable law, the aggregate principal amount of
Notes which may be authenticated and delivered under this Indenture is
unlimited. The Notes shall be executed by two Officers of the Company. The
signature of these Officers on the Notes may be by facsimile or manual signature
in the name and on behalf of the Company.

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

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

               At any time and from time to time after the execution of this
Indenture, the Trustee or an authenticating agent shall upon receipt of a
Company Order authenticate for original issue Notes in the aggregate principal
amount specified in such Company Order; provided that the Trustee shall be
entitled to receive an Officers' Certificate and an Opinion of Counsel of the
Company in connection with such authentication of Notes. Such Company Order
shall specify the amount of Notes to be authenticated and the date on which the
original issue of Notes is to be authenticated and, in case of an issuance of
Notes pursuant to Section 2.15, shall certify that such issuance is in
compliance with Article Four.

               The Trustee may appoint an authenticating agent to authenticate
the Notes. An authenticating agent may authenticate the Notes whenever the
Trustee may do so. Each reference in this Indenture to authentication by the
Trustee includes authentication by such authenticating agent. An authenticating
agent has the same rights as an Agent to deal with the Company or an Affiliate
of the Company.

                                       28
<PAGE>

               The Notes shall be issuable only in registered form without
coupons and only in denominations of $1,000 in principal amount and any integral
multiple thereof.

               SECTION 2.04. Registrar and Paying Agent. The Company shall
maintain an office or agency where Notes may be presented for registration of
transfer or for exchange (the "Registrar"), an office or agency where Notes may
be presented for payment (the "Paying Agent") and an office or agency where
notices and demands to or upon the Company in respect of the Notes and this
Indenture may be served, which shall be in the Borough of Manhattan, The City of
New York. The Company shall cause the Registrar to keep a register of the Notes
and of their transfer and exchange (the "Security Register"). The Security
Register shall be in written form or any other form capable of being converted
into written form within a reasonable time. The Company may have one or more
co-Registrars and one or more additional Paying Agents.

               The Company shall enter into an appropriate agency agreement with
any Agent not a party to this Indenture. The agreement shall implement the
provisions of this Indenture that relate to such Agent. The Company shall give
prompt written notice to the Trustee of the name and address of any such Agent
and any change in the address of such Agent. If the Company fails to maintain a
Registrar, Paying Agent and/or agent for service of notices and demands, the
Trustee shall act as such Registrar, Paying Agent and/or agent for service of
notices and demands. The Company may remove any Agent upon written notice to
such Agent and the Trustee; provided that no such removal shall become effective
until (i) the acceptance of an appointment by a successor Agent to such Agent as
evidenced by an appropriate agency agreement entered into by the Company and
such successor Agent and delivered to the Trustee or (ii) notification to the
Trustee that the Trustee shall serve as such Agent until the appointment of a
successor Agent in accordance with clause (i) of this proviso. The Company, any
Subsidiary of the Company, or any Affiliate of any of them may act as Paying
Agent, Registrar or co-Registrar, and/or agent for service of notice and
demands.

               The Company initially appoints the Trustee as Registrar, Paying
Agent, authenticating agent and agent for service of notice and demands. The
Trustee shall preserve in as current a form as is reasonably practicable the
most recent list available to it of the names and addresses of Holders and shall
otherwise comply with TIA Section 312(a). If the Trustee is not the Registrar,
the Company shall furnish to the Trustee as of each Regular Record Date and at
such other times as the Trustee may reasonably request the names and addresses
of Holders as they appear in the Security Register, including the aggregate
principal amount of Notes held by each Holder.

               SECTION 2.05. Paying Agent to Hold Money in Trust. Not later than
11:00 a.m. (New York City time) each due date of the principal, premium, if any,
and interest on any Notes, the Company shall deposit with the Paying Agent money
in immediately available funds sufficient to pay such principal, premium, if
any, and interest so becoming due. The Company shall require each Paying Agent
other than the Trustee to agree in writing that such Paying Agent shall hold in
trust for the benefit of the Holders or the Trustee all money held by the Paying
Agent for the payment of principal of, premium, if any, and interest on the
Notes (whether such money has been paid to it by the Company or any other
obligor on the Notes), and such Paying Agent shall promptly notify the Trustee
of any default by the Company (or any other obligor on the Notes) in making any
such payment. The Company at any time may require a Paying Agent

                                       29
<PAGE>

to pay all money held by it to the Trustee and account for any funds disbursed,
and the Trustee may at any time during the continuance of any payment default,
upon written request to a Paying Agent, require such Paying Agent to pay all
money held by it to the Trustee and to account for any funds disbursed. Upon
doing so, the Paying Agent shall have no further liability for the money so paid
over to the Trustee. If the Company or any Subsidiary of the Company or any
Affiliate of any of them acts as Paying Agent, it will, on or before each due
date of any principal of, premium, if any, or interest on the Notes, segregate
and hold in a separate trust fund for the benefit of the Holders a sum of money
sufficient to pay such principal, premium, if any, or interest so becoming due
until such sum of money shall be paid to such Holders or otherwise disposed of
as provided in this Indenture, and will promptly notify the Trustee of its
action or failure to act.

               SECTION 2.06. Transfer and Exchange. The Notes are issuable only
in registered form. A Holder may transfer a Note only by written application to
the Registrar stating the name of the proposed transferee and otherwise
complying with the terms of this Indenture. No such transfer shall be effected
until, and such transferee shall succeed to the rights of a Holder only upon,
final acceptance and registration of the transfer by the Registrar in the
Security Register. Prior to the registration of any transfer by a Holder as
provided herein, the Company, the Trustee, and any agent of the Company shall
treat the person in whose name the Note is registered as the owner thereof for
all purposes whether or not the Note shall be overdue, and neither the Company,
the Trustee, nor any such agent shall be affected by notice to the contrary.
Furthermore, any Holder of a Global Note shall, by acceptance of such Global
Note, agree that transfers of beneficial interests in such Global Note may be
effected only through a book entry system maintained by the Holder of such
Global Note (or its agent) and that ownership of a beneficial interest in the
Note shall be required to be reflected in a book entry. When Notes are presented
to the Registrar or a co-Registrar with a request to register the transfer or to
exchange them for an equal principal amount of Notes of other authorized
denominations (including an exchange of Notes for Exchange Notes), the Registrar
shall register the transfer or make the exchange as requested if its
requirements for such transactions are met (including that such Notes are duly
endorsed or accompanied by a written instrument of transfer in form satisfactory
to the Trustee and Registrar duly executed by the Holder thereof or by an
attorney who is authorized in writing to act on behalf of the Holder); provided
that no exchanges of Notes for Exchange Notes shall occur until a Registration
Statement shall have been declared effective by the Commission and that any
Notes that are exchanged for Exchange Notes shall be cancelled by the Trustee.
To permit registrations of transfers and exchanges, the Company shall execute
and the Trustee shall authenticate Notes at the Registrar's request. No service
charge shall be made for any registration of transfer or exchange or redemption
of the Notes, but the Company may require payment of a sum sufficient to cover
any transfer tax or similar governmental charge payable in connection therewith
(other than any such transfer taxes or other similar governmental charge payable
upon exchanges pursuant to Section 2.11, 3.08 or 9.04).

               The Registrar shall not be required (i) to issue, register the
transfer of or exchange any Note during a period beginning at the opening of
business 15 days before the day of the mailing of a notice of redemption of
Notes selected for redemption under Section 3.03 and ending at the close of
business on the day of such mailing, or (ii) to register the transfer of or
exchange any Note so selected for redemption in whole or in part, except the
unredeemed portion of any Note being redeemed in part.

                                       30
<PAGE>

               SECTION 2.07. Book-Entry Provisions for Global Notes. (a) The
U.S. Global Notes and Offshore Global Notes initially shall (i) be registered in
the name of the Depositary for such Global Notes or the nominee of such
Depositary, (ii) be delivered to the Trustee as custodian for such Depositary
and (iii) bear legends as set forth in Section 2.02.

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

               (b) Transfers of a Global Note shall be limited to transfers of
such Global Note in whole, but not in part, to the Depositary, its successors or
their respective nominees. Interests of beneficial owners in Global Notes may be
transferred in accordance with the rules and procedures of the Depositary and
the provisions of Section 2.08. In addition, U.S. Physical Notes and Offshore
Physical Notes shall be transferred to all beneficial owners in exchange for
their beneficial interests in the U.S. Global Notes or the Offshore Global
Notes, as the case may be, if (i) the Depositary notifies the Company that it is
unwilling or unable to continue as Depositary for the U.S. Global Notes or the
Offshore Global Notes, as the case may be, and a successor depositary is not
appointed by the Company within 90 days of such notice, (ii) an Event of Default
has occurred and is continuing and the Registrar has received a request from the
Depositary or (iii) in accordance with the rules and procedures of the
Depositary and the provisions of Section 2.08.

               (c) Any beneficial interest in one of the Global Notes that is
transferred to a person who takes delivery in the form of an interest in another
Global Note will, upon transfer, cease to be an interest in such Global Note and
become an interest in such other Global Note and, accordingly, will thereafter
be subject to all transfer restrictions, if any, and other procedures applicable
to beneficial interests in such other Global Note for as long as it remains such
an interest.

               (d) In connection with any transfer of a portion of the
beneficial interests in a Global Note to beneficial owners pursuant to paragraph
(b) of this Section 2.07, the Registrar shall reflect on its books and records
the date and a decrease in the principal amount of such Global Note in an amount
equal to the principal amount of the beneficial interest in such Global Note to
be transferred, and the Company shall execute, and the Trustee shall
authenticate and deliver, one or more U.S. Physical Notes or Offshore Physical
Notes, as the case may be, of like tenor and amount.

               (e) In connection with the transfer of the U.S. Global Notes or
the Offshore Global Notes, in whole, to beneficial owners pursuant to paragraph
(b) of this Section 2.07, the U.S. Global Notes or Offshore Global Notes, as the
case may be, shall be deemed to be surrendered to the Trustee for cancellation,
and the Company shall execute, and the Trustee shall

                                       31
<PAGE>

authenticate and deliver, to each beneficial owner identified by the Depositary
in exchange for its beneficial interest in the U.S. Global Notes or Offshore
Global Notes, as the case may be, an equal aggregate principal amount of U.S.
Physical Notes or Offshore Physical Notes, as the case may be, of authorized
denominations.

               (f) Any U.S. Physical Note delivered in exchange for an interest
in the U.S. Global Notes pursuant to paragraph (b), (d) or (e) of this Section
2.07 shall, except as otherwise provided by paragraph (f) of Section 2.08, bear
the legend regarding transfer restrictions applicable to the U.S. Physical Note
set forth in Section 2.02.

               (g) Any Offshore Physical Note delivered in exchange for an
interest in the Offshore Global Notes pursuant to paragraph (b), (d) or (e) of
this Section 2.07 shall, except as otherwise provided by paragraph (f) of
Section 2.08, bear the legend regarding transfer restrictions applicable to the
Offshore Physical Note set forth in Section 2.02.

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

               SECTION 2.08. Special Transfer Provisions. Unless and until a
Note is exchanged for an Exchange Note or sold in connection with an effective
Registration Statement pursuant to the Registration Rights Agreement, the
following provisions shall apply:

               (a) Transfers to Non-QIB Institutional Accredited Investors. The
following provisions shall apply with respect to the registration of any
proposed transfer of a Note to any Institutional Accredited Investor which is
not a QIB (excluding Non-U.S. Persons):

               (i) The Registrar shall register the transfer of any Note,
        whether or not such Note bears the Private Placement Legend, if (x) the
        requested transfer is after the time period referred to in Rule 144(k)
        under the Securities Act or (y) the proposed transferee has delivered to
        the Registrar (A) a certificate substantially in the form of Exhibit C
        hereto and (B) if the aggregate principal amount of the Notes being
        transferred is less than $100,000, an opinion of counsel acceptable to
        the Company that such transfer is in compliance with the Securities Act.

               (ii) If the proposed transferor is an Agent Member holding a
        beneficial interest in the U.S. Global Notes, upon receipt by the
        Registrar of (x) the documents, if any, required by paragraph (i) above
        and (y) instructions given in accordance with the Depositary's and the
        Registrar's procedures, the Registrar shall reflect on its books and
        records the date and a decrease in the principal amount of the U.S.
        Global Notes in an amount equal to the principal amount of the
        beneficial interest in the U.S. Global Notes to be transferred, and the
        Company shall execute, and the Trustee shall authenticate and deliver,
        one or more U.S. Physical Notes of like tenor and amount.

               (b) Transfers to QIBs. The following provisions shall apply with
respect to the registration of any proposed transfer of a Note to a QIB
(excluding Non-U.S. Persons):

               (i) If the Note to be transferred consists of (x) either Offshore
        Physical Notes prior to the removal of the Private Placement Legend or
        U.S. Physical Notes, the Registrar shall register the transfer if such
        transfer is being made by a proposed transferor who has checked the box
        provided for on the form of Note stating, or has otherwise advised the
        Company and the Registrar in writing, that the sale has been made in
        compliance with the provisions of Rule 144A to a transferee who has
        signed the certification provided for on the form of Note stating, or
        has otherwise advised the Company and the Registrar in writing, that it
        is purchasing the Note for its own account or an account with respect to
        which it exercises sole investment discretion and that it and any such
        account is a QIB within the meaning of Rule 144A and is aware that the
        sale to it is being made in reliance on Rule 144A and acknowledges that
        it has received such information regarding the Company as it has
        requested pursuant to Rule 144A or has determined not to request such
        information and that it is aware that the transferor is relying upon its
        foregoing representations in order to claim the exemption from
        registration provided by Rule 144A or (y) an interest in the U.S. Global
        Notes, the transfer of such interest may be effected only through the
        book entry system maintained by the Depositary.

               (ii) If the proposed transferee is an Agent Member, and the Note
        to be transferred consists of U.S. Physical Notes, upon receipt by the
        Registrar of the documents referred to in paragraph (i) above and
        instructions given in accordance with the Depositary's and the
        Registrar's procedures, the Registrar shall reflect on its books and
        records the date and an increase in the principal amount of U.S. Global
        Notes in an amount equal to the principal amount of the U.S. Physical
        Notes to be transferred, and the Trustee shall cancel the U.S. Physical
        Notes so transferred.

               (c) Transfers of Interests in the Legended Offshore Global Notes.
The following provisions shall apply with respect to registration of any
proposed transfer of an interest in the Legended Offshore Global Notes:

               (i) The Registrar shall register the transfer of any Note (x) if
        the proposed transferee is a Non-U.S. Person and the proposed transferor
        has delivered to the Registrar a certificate substantially in the form
        of Exhibit D hereto or (y) if the proposed transferee is a QIB and the
        proposed transferor has checked the box provided for on the form of Note
        stating, or has otherwise advised the Company and the Registrar in
        writing, that the sale has been made in compliance with the provisions
        of Rule 144A to a transferee who has signed the certification provided
        for on the form of Note stating, or has otherwise advised the Company
        and the Registrar in writing, that it is purchasing the Note for its own
        account or an account with respect to which it exercises sole investment
        discretion and that it and any such account is a QIB within the meaning
        of Rule 144A, and is aware that the sale to it is being made in reliance
        on Rule 144A and acknowledges that it has received such information
        regarding the Company as it has requested pursuant to Rule 144A or has
        determined not to request such information and that it is aware that the
        transferor is relying upon its foregoing representations in order to
        claim the exemption from registration provided by Rule 144A.

                                       33
<PAGE>

               (ii) If the proposed transferee is an Agent Member, upon receipt
        by the Registrar of the documents referred to in clause (i)(y) above and
        instructions given in accordance with the Depositary's and the
        Registrar's procedures, the Registrar shall reflect on its books and
        records the date and an increase in the principal amount of the U.S.
        Global Notes in an amount equal to the principal amount of the Legended
        Offshore Global Notes to be transferred, and the Trustee shall decrease
        the amount of the Legended Offshore Global Notes.

               (d) Transfers of Interests in the Unlegended Offshore Global
Notes or Unlegended Offshore Physical Notes. The following provision shall apply
with respect to any transfer of interests in Unlegended Offshore Global Notes or
unlegended Offshore Physical Notes: The Registrar shall register the transfer of
any such Note without requiring any additional certification.

               (e) Transfers to Non-U.S. Persons at Any Time. The following
provisions shall apply with respect to any transfer of a Note to a Non-U.S.
Person:

               (i) Prior to July 1, 2002, the Registrar shall register any
        proposed transfer of a Note to a Non-U.S. Person upon receipt of a
        certificate substantially in the form of Exhibit D hereto from the
        proposed transferor.

               (ii) On and after July 1, 2002, the Registrar shall register any
        proposed transfer to any Non-U.S. Person if the Note to be transferred
        is a U.S. Physical Note or an interest in U.S. Global Notes, upon
        receipt of a certificate substantially in the form of Exhibit D hereto
        from the proposed transferor.

                (iii) (a) If the proposed transferor is an Agent Member holding
        a beneficial interest in the U.S. Global Notes, upon receipt by the
        Registrar of (x) the documents, if any, required by paragraph (ii) and
        (y) instructions in accordance with the Depositary's and the Registrar's
        procedures, the Registrar shall reflect on its books and records the
        date and a decrease in the principal amount of the U.S. Global Notes in
        an amount equal to the principal amount of the beneficial interest in
        the U.S. Global Notes to be transferred, and (b) if the proposed
        transferee is an Agent Member, upon receipt by the Registrar of
        instructions given in accordance with the Depositary's and the
        Registrar's procedures, the Registrar shall reflect on its books and
        records the date and an increase in the principal amount of the Offshore
        Global Notes in an amount equal to the principal amount of the U.S.
        Physical Notes or the U.S. Global Notes, as the case may be, to be
        transferred, and the Trustee shall cancel the Physical Note, if any, so
        transferred or decrease the amount of the U.S. Global Notes.

               (f) Private Placement Legend. Upon the transfer, exchange or
replacement of Notes not bearing the Private Placement Legend, the Registrar
shall deliver Notes that do not bear the Private Placement Legend. Upon the
transfer, exchange or replacement of Notes bearing the Private Placement Legend,
the Registrar shall deliver only Notes that bear the Private Placement Legend
unless (i) the Private Placement Legend is no longer required by Section 2.02,
(ii) the circumstances contemplated by paragraph (a)(i)(x) of this Section 2.08
exist or (iii) there is delivered to the Registrar an Opinion of Counsel
reasonably satisfactory to the Company and

                                       34
<PAGE>

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.

               (g) General. By its acceptance of any Note bearing the Private
Placement Legend, each Holder of such a Note acknowledges the restrictions on
transfer of such Note set forth in this Indenture and in the Private Placement
Legend and agrees that it will transfer such Note only as provided in this
Indenture. The Registrar shall not register a transfer of any Note unless such
transfer complies with the restrictions on transfer of such Note set forth in
this Indenture. In connection with any transfer of Notes, each Holder agrees by
its acceptance of the Notes to furnish the Registrar or the Company such
certifications, legal opinions or other information as either of them may
reasonably require to confirm that such transfer is being made pursuant to an
exemption from, or a transaction not subject to, the registration requirements
of the Securities Act; provided that the Registrar 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 transfers of any interest in any Note (including any transfers between or
among DTC participants, members or beneficial owners in any Global Note) 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 thereof.

               The Registrar shall retain copies of all letters, notices and
other written communications received pursuant to Section 2.07 or this Section
2.08. The Company shall have the right to inspect and make copies of all such
letters, notices or other written communications at any reasonable time upon the
giving of reasonable written notice to the Registrar.

               SECTION 2.09. Replacement Notes. If a mutilated Note is
surrendered to the Trustee or if the Holder claims that the Note has been lost,
destroyed or wrongfully taken, then, in the absence of notice to the Company or
the Trustee that such Note has been acquired by a bona fide purchaser, the
Company shall issue and the Trustee shall authenticate a replacement Note of
like tenor and principal amount and bearing a number not contemporaneously
outstanding; provided that the requirements of this Section 2.09 are met. If
required by the Trustee or the Company, an indemnity bond must be furnished that
is sufficient in the judgment of both the Trustee and the Company to protect the
Company, the Trustee or any Agent from any loss that any of them may suffer if a
Note is replaced. The Company may charge such Holder for its expenses and the
expenses of the Trustee in replacing a Note. In case any such mutilated, lost,
destroyed or wrongfully taken Note has become or is about to become due and
payable, the Company in its discretion may pay such Note instead of issuing a
new Note in replacement thereof.

               Every replacement Note is an additional obligation of the Company
and shall be entitled to the benefits of this Indenture.

               SECTION 2.10. Outstanding Notes. Notes outstanding at any time
are all Notes that have been authenticated by the Trustee except for those
cancelled by it, those delivered to it for cancellation and those described in
this Section 2.10 as not outstanding.

                                       35
<PAGE>

               If a Note is replaced pursuant to Section 2.09, it ceases to be
outstanding unless and until the Trustee and the Company receive proof
satisfactory to them that the replaced Note is held by a bona fide purchaser.

               If the Paying Agent (other than the Company or an Affiliate of
the Company) holds on the maturity date money sufficient to pay Notes payable on
that date, then on and after that date such Notes cease to be outstanding and
interest on them shall cease to accrue.

               A Note does not cease to be outstanding because the Company or
one of its Affiliates holds such Note, provided, however, that in determining
whether the Holders of the requisite principal amount of the outstanding Notes
have given any request, demand, authorization, direction, notice, consent or
waiver hereunder, Notes owned by the Company or any other obligor upon the Notes
or any Affiliate of the Company or of such other obligor shall be disregarded
and deemed not to be outstanding, except that, in determining whether the
Trustee shall be protected in relying upon any such request, demand,
authorization, direction, notice, consent or waiver, only Notes which a
Responsible Officer of the Trustee has actual knowledge to be so owned shall be
so disregarded. Notes so owned which have been pledged in good faith may be
regarded as outstanding if the pledgee establishes to the satisfaction of the
Trustee the pledgee's right so to act with respect to such Notes and that the
pledgee is not the Company or any other obligor upon the Notes or any Affiliate
of the Company or of such other obligor.

               SECTION 2.11. Temporary Notes. Until definitive Notes are ready
for delivery, the Company may prepare and execute and the Trustee shall
authenticate temporary Notes. Temporary Notes shall be substantially in the form
of definitive Notes but may have insertions, substitutions, omissions and other
variations determined to be appropriate by the Officers executing the temporary
Notes, as evidenced by their execution of such temporary Notes. If temporary
Notes are issued, the Company will cause definitive Notes to be prepared without
unreasonable delay. After the preparation of definitive Notes, the temporary
Notes shall be exchangeable for definitive Notes upon surrender of the temporary
Notes at the office or agency of the Company designated for such purpose
pursuant to Section 4.02, without charge to the Holder. Upon surrender for
cancellation of any one or more temporary Notes the Company shall execute and
the Trustee shall authenticate and deliver in exchange therefore a like
principal amount of definitive Notes of authorized denominations. Until so
exchanged, the temporary Notes shall be entitled to the same benefits under this
Indenture as definitive Notes.

               SECTION 2.12. Cancellation. The Company at any time may deliver
to the Trustee for cancellation any Notes previously authenticated and delivered
hereunder which the Company may have acquired in any manner whatsoever, and may
deliver to the Trustee for cancellation any Notes previously authenticated
hereunder which the Company has not issued and sold. The Registrar and the
Paying Agent shall forward to the Trustee any Notes surrendered to them for
transfer, exchange or payment. The Trustee shall cancel all Notes surrendered
for transfer, exchange, payment or cancellation and shall destroy them in
accordance with its normal procedure.

               SECTION 2.13. CUSIP Numbers. The Company in issuing the Notes may
use "CUSIP", "CINS" or "ISIN" numbers (if then generally in use), and the
Company and the Trustee shall use CUSIP, CINS or ISIN numbers, as the case may
be, in notices of redemption or

                                       36
<PAGE>

exchange as a convenience to Holders; provided that no representation is made
and any such notice shall state that no representation is made, as to the
correctness of such numbers either as printed on the Notes or as contained in
any notice of redemption or exchange and that reliance may be placed only on the
other identification numbers printed on the Notes. The Company shall promptly
notify the Trustee of any change in "CUSIP", "CINS" or "ISIN" numbers for the
Notes.

               SECTION 2.14. Defaulted Interest. If the Company defaults in a
payment of interest on the Notes, it shall pay, or shall deposit with the Paying
Agent money in immediately available funds sufficient to pay, the defaulted
interest, plus (to the extent lawful) any interest payable on the defaulted
interest, to the Persons who are Holders on a subsequent special record date. A
special record date, as used in this Section 2.14 with respect to the payment of
any defaulted interest, shall mean the 15th day next preceding the date fixed by
the Company for the payment of defaulted interest, whether or not such day is a
Business Day. At least 15 days before the subsequent special record date, the
Company shall mail to each Holder and to the Trustee a notice that states the
subsequent special record date, the payment date and the amount of defaulted
interest to be paid.

               SECTION 2.15. Issuance of Additional Notes. The Company may,
subject to Article Four of this Indenture and applicable law, issue additional
Notes under this Indenture. The Notes issued on the Closing Date and any
additional Notes subsequently issued shall be treated as a single class for all
purposes under this Indenture.

               SECTION 2.16. Registration Default. The interest rate borne by
the Notes may be increased as provided in the Notes. If such an increase occurs,
the Company shall provide prompt written notice to the Trustee stating (i) the
increase in the interest rate, (ii) when such increase is effective, and (iii)
when such additional interest is payable. Unless and until the Trustee shall
receive such a certificate, the Trustee may assume without inquiry that the
interest rate has not been increased.

                                  ARTICLE THREE
                                   REDEMPTION

               SECTION 3.01. Right of Redemption. (a) The Notes are redeemable,
at the Company's option, in whole or in part, at any time or from time to time,
on or after June 1, 2006 and prior to maturity, at the following Redemption
Prices (expressed in percentages of principal amount), plus accrued and unpaid
interest to the Redemption Date (subject to the right of Holders of record on
the relevant Regular Record Date that is prior to the Redemption Date to receive
interest due on an Interest Payment Date), if redeemed during the 12-month
period commencing June 1 of the years set forth below:

<PAGE>

               (b) In addition, at any time prior to June 1, 2005, the Company
may redeem up to 35% of the aggregate principal amount of the Notes with the Net
Cash Proceeds of one or more sales of its Capital Stock (other than Disqualified
Stock), at any time as a whole or from time to time in part, at a Redemption
Price (expressed as a percentage of principal amount) of 110.750%, plus accrued
and unpaid interest to the Redemption Date (subject to the rights of Holders of
record on the relevant Regular Record Date that is prior to the Redemption Date
to receive interest due on an Interest Payment Date); provided that (i) at least
65% of the aggregate principal amount of Notes originally issued on the Closing
Date remains outstanding after each such redemption and (ii) notice of such
redemption is mailed within 60 days of each such sale of Capital Stock.

               (c) At any time on or prior to June 1, 2006, the Notes may be
redeemed, in whole but not in part, at the option of the Company upon the
occurrence of a Change of Control (but in no event more than 90 days after the
occurrence of such Change of Control), at a redemption price equal to 100% of
the principal amount thereof plus the Applicable Premium as of, and accrued and
unpaid interest, to, the Redemption Date. The Company shall calculate the
Applicable Premium and provide notice of such amount to the Trustee not later
than one Business Day prior to the Redemption Date. The Trustee shall be
entitled to rely on such calculation.

               SECTION 3.02. Notices to Trustee. If the Company elects to redeem
Notes pursuant to Section 3.01, it shall notify the Trustee in writing of the
Redemption Date and the principal amount of Notes to be redeemed and the clause
of this Indenture pursuant to which redemption shall occur.

               The Company shall give the Trustee notice of any redemption
pursuant to this Section 3.02 in an Officers' Certificate at least 45 days
before the Redemption Date (unless a shorter period shall be satisfactory to the
Trustee).

               SECTION 3.03. Selection of Notes to Be Redeemed. If less than all
of the Notes are to be redeemed at any time, the Trustee shall select the Notes
to be redeemed in compliance with the requirements of the principal national
securities exchange, if any, on which the Notes are listed or, if the Notes are
not listed on a national securities exchange or automated quotation system, by
lot or by such other customary method as the Trustee in its sole discretion
shall deem fair and appropriate; provided that no Note of $1,000 in principal
amount or less shall be redeemed in part.

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

                                       38
<PAGE>

               SECTION 3.04. Notice of Redemption. With respect to any
redemption of Notes pursuant to Section 3.01, at least 30 days but not more than
60 days before a Redemption Date, the Company shall mail a notice of redemption
by first-class mail to each Holder whose Notes are to be redeemed.

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

               (i) the Redemption Date;

               (ii) the Redemption Price;

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

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

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

               (vi) that, if any Note is being redeemed in part, the portion of
        the principal amount (equal to $1,000 in principal amount or any
        integral multiple thereof) of such Note to be redeemed and that, on and
        after the Redemption Date, upon surrender of such Note, a new Note or
        Notes in principal amount equal to the unredeemed portion thereof will
        be reissued; and

               (vii) that, if any Note contains a CUSIP, CINS or ISIN number as
        provided in Section 2.13, no representation is being made as to the
        correctness of the CUSIP, CINS or ISIN number either as printed on the
        Notes or as contained in the notice of redemption and that reliance may
        be placed only on the other identification numbers printed on the Notes.

               At the Company's request (which request may be revoked by the
Company at any time prior to the time at which the Trustee shall have given such
notice to the Holders), made in writing to the Trustee at least 45 days (or such
shorter period as shall be satisfactory to the Trustee) before a Redemption
Date, the Trustee shall give the notice of redemption in the name and at the
expense of the Company. If, however, the Company gives such notice to the
Holders, the Company shall concurrently deliver to the Trustee an Officers'
Certificate stating that such notice has been given.

               SECTION 3.05. Effect of Notice of Redemption. Once notice of
redemption is mailed, Notes called for redemption become due and payable on the
Redemption Date and at the Redemption Price. Upon surrender of any Notes to the
Paying Agent, such Notes shall be paid at the Redemption Price, plus accrued
interest, if any, to the Redemption Date.

                                       39
<PAGE>

               Notice of redemption shall be deemed to be given when mailed,
whether or not the Holder receives the notice. In any event, failure to give
such notice, or any defect therein, shall not affect the validity of the
proceedings for the redemption of Notes held by Holders to whom such notice was
properly given.

               SECTION 3.06. Deposit of Redemption Price. No later than 11:00
a.m. (New York time) on any Redemption Date, the Company shall deposit with the
Paying Agent (or, if the Company is acting as its own Paying Agent, shall
segregate and hold in trust as provided in Section 2.05) money sufficient to pay
the Redemption Price of and accrued interest on all Notes to be redeemed on that
date other than Notes or portions thereof called for redemption on that date
that have been delivered by the Company to the Trustee for cancellation.

               SECTION 3.07. Payment of Notes Called for Redemption. If notice
of redemption has been given in the manner provided above, the Notes or portion
of Notes specified in such notice to be redeemed shall become due and payable on
the Redemption Date at the Redemption Price stated therein, together with
accrued interest to such Redemption Date, and on and after such date (unless the
Company shall default in the payment of such Notes at the Redemption Price and
accrued interest to the Redemption Date, in which case the principal, until
paid, shall bear interest from the Redemption Date at the rate prescribed in the
Notes), such Notes shall cease to accrue interest. Upon surrender of any Note
for redemption in accordance with a notice of redemption, such Note shall be
paid and redeemed by the Company at the Redemption Price, together with accrued
interest, if any, to the Redemption Date; provided that installments of interest
whose Stated Maturity is on or prior to the Redemption Date shall be payable to
the Holders registered as such at the close of business on the relevant Regular
Record Date.

               SECTION 3.08. Notes Redeemed in Part. Upon surrender of any Note
that is redeemed in part, the Company shall execute and the Trustee shall
authenticate and deliver to the Holder without service charge, a new Note equal
in principal amount to the unredeemed portion of such surrendered Note.

                                  ARTICLE FOUR
                                    COVENANTS

               SECTION 4.01. Payment of Notes. The Company shall pay the
principal of, premium, if any, and interest on the Notes on the dates and in the
manner provided in the Notes and this Indenture. An installment of principal,
premium, if any, or interest shall be considered paid on the date due if the
Trustee or Paying Agent (other than the Company, a Subsidiary of the Company, or
any Affiliate of any of them) holds at 11:00 a.m. New York time on that date
money designated for and sufficient to pay the installment. If the Company or
any Subsidiary of the Company or any Affiliate of any of them acts as Paying
Agent, an installment of principal, premium, if any, or interest shall be

               The Company shall pay interest on overdue principal and premium,
if any, and interest on overdue installments of interest, to the extent lawful,
at the rate per annum specified in the Notes.

               SECTION 4.02. Maintenance of Office or Agency. The Company will
maintain in the Borough of Manhattan, The City of New York an office or agency
where Notes may be surrendered for registration of transfer or exchange or for
presentation for payment and where notices and demands to or upon the Company in
respect of the Notes and this Indenture may be served. The Company will give

may be made or served at the address of the Trustee set forth in Section 11.02.

               The Company may also from time to time designate one or more
other offices or agencies where the Notes may be presented or surrendered for
any or all such purposes and may from time to time rescind such designations;
provided that no such designation or rescission shall in any manner relieve the
Company of its obligation to maintain an office or agency in the Borough of

               SECTION 4.03. Limitation on Indebtedness.

               (a) The Company will not, and will not permit any of its
Restricted Subsidiaries to, Incur any Indebtedness (other than the Notes, the
Note Guarantees, the 7% Senior Notes due 2003 and other Indebtedness existing on
the Closing Date); provided that the Company or any Subsidiary Guarantor may
Incur Indebtedness, and any Restricted Subsidiary may Incur Acquired
Indebtedness, if, after giving effect to the Incurrence of such Indebtedness and
the receipt and application of the proceeds therefrom, the Interest Coverage
Ratio would be greater than 2.00 to 1.00.

               Notwithstanding the foregoing, the Company and any Restricted
Subsidiary (except as specified below) may Incur each and all of the following:

               (1) Indebtedness of the Company or any Restricted Subsidiary
        under the Credit Agreement outstanding at any time in an aggregate

        permanently repaid as provided in Section 4.11 and (y) 70% of Adjusted
        Consolidated Net Tangible Assets (determined as of the date of the most
        recent consolidated balance sheet of the Company and its Subsidiaries

        Guarantor evidenced by a promissory note or (B) to any other Restricted
        Subsidiary; provided that (x) any event which results in any such
        Restricted Subsidiary ceasing to be a Restricted Subsidiary or any
        subsequent transfer of such Indebtedness (other than to the Company or
        another Restricted Subsidiary) shall be deemed, in each case, to
        constitute an Incurrence of such Indebtedness not permitted by this
        clause (2) and (y) if the Company or any Subsidiary Guarantor is the
        obligor on such Indebtedness, such Indebtedness must be expressly
        subordinated in right of payment to the Notes except to the extent not
        permitted by applicable law or any regulation or order of, or
        arrangement with, any regulatory body or agency, in the case of the
        Company or the Note Guarantee, in the case of a Subsidiary Guarantor;

               (3) Indebtedness issued in exchange for, or the net proceeds of
        which are used to extend, renew, replace, defease, refinance or refund,

        clause (2) or (6)) and any refinancings thereof in an amount not to
        exceed the amount so refinanced or refunded (plus penalties, premiums,
        including redemption premiums and any premiums reasonably determined by
        the Company as necessary to accomplish such exchange, extension,
        renewal, replacement, defeasance, refinancing or refund by means of a
        tender offer or privately negotiated repurchase, accrued interest, fees
        and expenses); provided that (a) Indebtedness the proceeds of which are
        used to refinance or refund the Notes or Indebtedness that is pari passu
        with, or subordinated in right of payment to, the Notes or a Note
        Guarantee shall only be permitted under this clause (3) if (x) in case
        the Notes are refinanced in part or the Indebtedness to be refinanced is
        pari passu with the Notes or a Note Guarantee, such new Indebtedness, by
        its terms or by the terms of any agreement or instrument pursuant to
        which such new Indebtedness is outstanding, is expressly made pari passu
        with, or subordinate in right of payment to, the remaining Notes or the
        Note Guarantee, or (y) in case the Indebtedness to be refinanced is
        subordinated in right of payment to the Notes or a Note Guarantee, such
        new Indebtedness, by its terms or by the terms of any agreement or
        instrument pursuant to which such new Indebtedness is issued or remains
        outstanding, is expressly made subordinate in right of payment to the

        such new Indebtedness, determined as of the date of Incurrence of such
        new Indebtedness, does not mature prior to the Stated Maturity of the
        Indebtedness to be extended, renewed, replaced, defeased, refinanced or
        refunded, and the Average Life of such new Indebtedness is at least
        equal to the remaining Average Life of the Indebtedness to be extended,
        renewed, replaced, defeased, refinanced or refunded and (c) such new
        Indebtedness is Incurred by the Company or a Subsidiary Guarantor or by
        the Restricted Subsidiary who is the obligor on the Indebtedness to be
        extended, renewed, replaced, defeased, refinanced or refunded;

               (4) Indebtedness issued in exchange for, or the net proceeds of

        account or escrow account for the purpose of prepaying, redeeming,
        purchasing, defeasing or satisfying in full the 7% Senior Notes due
        2003, provided, however, such Indebtedness is an obligation of
        PacifiCare and such

                                       42

        defease the Notes as provided in Article Eight;

               (6) Guarantees of the Notes and Guarantees of Indebtedness of the

        aggregate principal amount (together with refinancings thereof) not to
        exceed $100 million; provided, however, that the aggregate principal

        that may be Incurred under this clause (10) by Restricted Subsidiaries
        that are not Subsidiary Guarantors shall not exceed $25 million.

               (b) Notwithstanding any other provision of this Section 4.03, the
maximum amount of Indebtedness that may be Incurred pursuant to this Section
4.03 will not be deemed to be exceeded, with respect to any outstanding
Indebtedness due solely to the result of fluctuations in the exchange rates of
currencies.

               (c) For purposes of determining any particular amount of
Indebtedness under this Section 4.03, (x) Indebtedness Incurred under the Credit
Agreement on or prior to the Closing Date shall be treated as Incurred pursuant

               (13) the declaration or payment of dividends on the Capital Stock
        (other than Disqualified Stock) of the Company in an aggregate annual
        amount not to exceed 6% of the Net Cash Proceeds received by the Company
        after the Closing Date from the sale of such Capital Stock;

               (14) payments of cash in lieu of the issuance of fractional
        shares upon the exercise of warrants or upon the conversion or exchange
        of, or issuance of Capital Stock in lieu of cash dividends on, any
        Capital Stock of the Company, which in the aggregate do not exceed $3.0
        million;

                                       47
<PAGE>

               (15) redemption of rights issued pursuant to the Company's Rights
        Plan in an aggregate amount not to exceed $1.5 million; or

               (16) Restricted Payments in an aggregate amount not to exceed $20
        million, plus the net reduction in any Investments made pursuant to this
        clause resulting from distributions on or repayments of such Investments
        or from the Net Cash Proceeds or Temporary Cash Investments from the
        sale or other disposition of any such Investment (except, in each case,
        to the extent any such payment or proceeds are included in the
        calculation of Adjusted Consolidated Net Income); provided that such
        reduction does not exceed the amount of such Investment;

provided that, except in the case of clauses (1) and (3), no Default or Event of
Default shall have occurred and be continuing or occur as a consequence of the
actions or payments set forth therein.

               Each Restricted Payment permitted pursuant to the preceding
paragraph (other than the Restricted Payments referred to in clauses (2), (7),
(8), (9), (12), (14) and (15) thereof, an exchange of Capital Stock for Capital
Stock or Indebtedness referred to in clause (3) or (4) thereof and an Investment
acquired as a capital contribution or in exchange for Capital Stock referred to
in clause (6) thereof), and the Net Cash Proceeds from any issuance of Capital
Stock referred to in clauses (3), (4) or (6), shall be included in calculating
whether the conditions of clause (C) of the first paragraph of this Section 4.04
have been met with respect to any subsequent Restricted Payments. In the event
the proceeds of an issuance of Capital Stock of the Company are used for the
redemption, repurchase or other acquisition of the Notes, or Indebtedness that
is pari passu with the Notes or any Note Guarantee, then the Net Cash Proceeds
of such issuance shall be included in clause (C) of the first paragraph of this
Section 4.04 only to the extent such proceeds are not used for such redemption,
repurchase or other acquisition of Indebtedness.

               For purposes of determining compliance with this Section 4.04,
(x) the amount, if other than in cash, of any Restricted Payment shall be
determined in good faith by the Board of Directors, whose determination shall be
conclusive and evidenced by a Board Resolution and (y) in the event that a
Restricted Payment meets the criteria of more than one of the types of
Restricted Payments described in the above clauses, including the first
paragraph of this Section 4.04, the Company, in its sole discretion, may order
and classify, and from time to time may reclassify, such Restricted Payment if
it would have been permitted at the time such Restricted Payment was made and at
the time of such reclassification.

               SECTION 4.05. Limitation on Dividend and Other Payment
Restrictions Affecting Restricted Subsidiaries.

               The Company will not, and will not permit any Restricted
Subsidiary to, create or otherwise cause or suffer to exist or become effective
any consensual encumbrance or restriction of any kind on the ability of any
Restricted Subsidiary to (1) pay dividends or make any other distributions
permitted by applicable law on any Capital Stock of such Restricted Subsidiary
owned by the Company or any other Restricted Subsidiary, (2) pay any
Indebtedness owed to the Company or any other Restricted Subsidiary, (3) make
loans or advances to the Company or any

                                       48
<PAGE>

other Restricted Subsidiary or (4) transfer any of its property or assets to the
Company or any other Restricted Subsidiary.

               The foregoing provisions shall not restrict any encumbrances or
restrictions:

               (1) existing on the Closing Date in the Credit Agreement, the
        indenture for the 7% Senior Notes due 2003, this Indenture or any other
        agreements in effect on the Closing Date, and any amendments,
        modifications, restatements, supplements, refundings, extensions,
        refinancings, renewals or replacements of such agreements; provided that
        the encumbrances and restrictions in any such amendments, modifications,
        restatements, supplements, refundings, extensions, refinancings,
        renewals or replacements taken as a whole are no less favorable in any
        material respect to the Holders than those encumbrances or restrictions
        that are then in effect and that are being amended, modified, restated,
        supplemented, refunded, extended, refinanced, renewed or replaced;

               (2) existing under or by reason of applicable law or any
        applicable rule, regulation or order of, or arrangement with, any
        regulatory body or agency;

               (3) existing with respect to any Person or the property or assets
        of such Person acquired by the Company or any Restricted Subsidiary,
        under agreements existing at the time of such acquisition and not
        incurred in contemplation thereof, which encumbrances or restrictions
        are not applicable to any Person or the property or assets of any Person
        other than such Person or the property or assets of such Person so
        acquired and any amendments, modifications, restatements, supplements,
        refundings, extensions, refinancings, renewals or replacements of such
        agreements; provided that the encumbrances and restrictions in any such
        amendments, modifications, restatements, supplements, refundings,
        extensions, refinancings, renewals or replacements taken as a whole are
        no less favorable in any material respect to the Holders than those
        encumbrances or restrictions that are then in effect and that are being
        amended, modified, restated, supplemented, refunded, extended,
        refinanced, renewed or replaced;

               (4) in the case of clause (4) of the first paragraph of this
        Section 4.05:

                      (A) that restrict in a customary manner the subletting,
               assignment or transfer of any property or asset that is, or is
               subject to, a lease, license, right, conveyance or contract or
               similar property or asset, including, without limitation,
               customary non-assignment provisions in leases, purchase money
               obligations and other similar agreements, in each case with
               respect to the property or assets subject thereto,

                      (B) existing by virtue of any sale, disposition, transfer
               of, agreement to sell, dispose or transfer, option or right with
               respect to, or Lien on, any property or assets of the Company or
               any Restricted Subsidiary not otherwise prohibited by this
               Indenture,

                      (C) arising or agreed to in the ordinary course of
               business, not relating to any Indebtedness, and that do not,
               individually or in the aggregate, detract from

                                       49
<PAGE>

               the value of property or assets of the Company or any Restricted
               Subsidiary in any manner material to the Company or any
               Restricted Subsidiary, or

                      (D) restrictions on cash or deposits required by insurance
               companies or health maintenance organizations under contracts
               entered into in the ordinary course of business;

               (5) with respect to a Restricted Subsidiary and imposed pursuant
        to an agreement that has been entered into for the sale or disposition
        of all or substantially all of the Capital Stock of, or property and
        assets of, such Restricted Subsidiary;

               (6) imposed by customary provisions in joint venture agreements
        and similar agreements that restrict the transfer of the interest in the
        joint venture; or

               (7) with respect to a Subsidiary Guarantor, contained in the
        terms of any Indebtedness or any agreement pursuant to which such
        Indebtedness was issued if the encumbrance or restriction is not
        materially more disadvantageous to the Holders than is customary in
        comparable financings and the Company determines that any such
        encumbrance or restriction will not materially affect the Company's
        ability to make principal or interest payments on the Notes.

               Nothing contained in this Section 4.05 shall prevent the Company
or any Restricted Subsidiary from (1) creating, incurring, assuming or suffering
to exist any Liens otherwise permitted in Section 4.09 or (2) restricting the
sale or other disposition of property or assets of the Company or any of its
Restricted Subsidiaries that secure Indebtedness of the Company or any of its
Restricted Subsidiaries.

               SECTION 4.06. Limitation on the Issuance and Sale of Capital
Stock of Restricted Subsidiaries.

               The Company will not sell, and will not permit any Restricted
Subsidiary, directly or indirectly, to issue or sell, any shares of Capital
Stock of a Restricted Subsidiary (including options, warrants or other rights to
purchase shares of such Capital Stock) except:

               (1) to the Company or a Wholly Owned Restricted Subsidiary;

               (2) issuances of director's qualifying shares or sales to foreign
        nationals of shares of Capital Stock of foreign Restricted Subsidiaries,
        to the extent required by applicable law;

               (3) if, immediately after giving effect to such issuance or sale,
        such Restricted Subsidiary would no longer constitute a Restricted
        Subsidiary and any Investment in such Person remaining after giving
        effect to such issuance or sale would have been permitted to be made
        under Section 4.04 if made on the date of such issuance or sale; or

               (4) sales of Common Stock (including options, warrants or other
        rights to purchase shares of such Common Stock) of a Restricted
        Subsidiary, provided that the

                                       50
<PAGE>

        Company or such Restricted Subsidiary applies the Net Cash Proceeds of
        any such sale in accordance with clause (A), (B) or (C) of Section 4.11.

               SECTION 4.07. Limitation on Issuances of Guarantees by Restricted
Subsidiaries.

               The Company will cause each Restricted Subsidiary (other than the
PHPA Subsidiary Guarantors) that would be permitted to guarantee payment of the
Notes without obtaining the approval of governmental or regulatory agencies or
authorities or incurring regulatory restrictions on the operations of such
subsidiary (other than any Foreign Subsidiary) to execute and deliver a
supplemental indenture to this Indenture providing for an unsubordinated
Guarantee (a "Subsidiary Guarantee") of payment of the Notes by such Restricted
Subsidiary. Immediately upon the prepayment, redemption, purchase, defeasance or
other satisfaction in full of the 7% Senior Notes due 2003, or upon any waiver,
modification or amendment of the provisions in the documents governing the 7%
Senior Notes due 2003 so that such documents no longer restrict the ability of
the PHPA Subsidiary Guarantors to guarantee the payment of the Notes, PacifiCare
will cause each PHPA Subsidiary Guarantor to fully and unconditionally
Guarantee, jointly and severally, on an unsecured unsubordinated basis the
payment of principal, premium, if any, and interest on the Notes by the
execution and delivery of a supplemental indenture to the Indenture (such
Guarantee shall for all purposes herein be deemed a Subsidiary Guarantee).

               The Company will not permit any Restricted Subsidiary which is
not a Subsidiary Guarantor, directly or indirectly, to Guarantee any
Indebtedness ("Guaranteed Indebtedness") (other than Indebtedness outstanding
under the Credit Agreement) of the Company or any other Restricted Subsidiary
(other than a Foreign Subsidiary), unless (a) such Restricted Subsidiary
simultaneously executes and delivers a supplemental indenture to this Indenture
providing for a Subsidiary Guarantee and (b) such Restricted Subsidiary waives
and will not in any manner whatsoever claim or take the benefit or advantage of,
any rights of reimbursement, indemnity or subrogation or any other rights
against the Company or any other Restricted Subsidiary as a result of any
payment by such Restricted Subsidiary under its Subsidiary Guarantee until the
Notes have been paid in full.

               If the Guaranteed Indebtedness is (A) pari passu in right of
payment with the Notes or any Notes Guarantee, then the Guarantee of such
Guaranteed Indebtedness shall be pari passu in right of payment with, or
subordinated to, the Subsidiary Guarantee or (B) subordinated in right of
payment to the Notes or any Note Guarantee, then the Guarantee of such
Guaranteed Indebtedness shall be subordinated in right of payment to the
Subsidiary Guarantee at least to the extent that the Guaranteed Indebtedness is
subordinated to the Notes or the Notes Guarantee.

               Notwithstanding the foregoing, any Subsidiary Guarantee by a
Restricted Subsidiary may provide by its terms that it shall be automatically
and unconditionally released and discharged without any further action required
on the part of the Trustee or any Holder, upon:

               (1) the sale, exchange, transfer or other disposition, to any
        Person not an Affiliate of the Company, of all of the Company's and each
        Restricted Subsidiary's

                                       51
<PAGE>

        Capital Stock in, or all or substantially all the assets of, such
        Restricted Subsidiary (which sale, exchange or transfer is not
        prohibited by this Indenture) or upon the designation of such Restricted
        Subsidiary as an Unrestricted Subsidiary in accordance with the terms of
        this Indenture; or

               (2) the release or discharge of the Guarantee which resulted in
        the creation of such Subsidiary Guarantee (as well as the release or
        discharge of any subsequently created Guarantees which would have
        resulted in the creation of such Subsidiary Guarantee if same did not
        already exist), except a discharge or release by or as a result of
        payment under such Guarantee.

               SECTION 4.08. Limitation on Transactions with Stockholders and
Affiliates.

               The Company will not, and will not permit any Restricted
Subsidiary to, directly or indirectly, enter into, renew or extend any
transaction (including, without limitation, the purchase, sale, lease or
exchange of property or assets, or the rendering of any service) with any holder
(or any Affiliate of such holder) of 10% or more of any class of Capital Stock
of the Company or with any Affiliate of the Company or any Restricted
Subsidiary, except upon fair and reasonable terms no less favorable to the
Company or such Restricted Subsidiary than could be obtained, at the time of
such transaction or, if such transaction is pursuant to a written agreement, at
the time of the execution of the agreement providing therefor, in a comparable
arm's-length transaction with a Person that is not such a holder or an
Affiliate.

               The foregoing limitation does not limit, and shall not apply to:

               (1) transactions (A) approved by a majority of the disinterested
        members of the Board of Directors or (B) for which the Company or a
        Restricted Subsidiary delivers to the Trustee a written opinion of a
        nationally recognized investment banking, accounting, valuation or
        appraisal firm stating that the transaction is fair to the Company or
        such Restricted Subsidiary from a financial point of view;

               (2) any transaction solely between (a) the Company and any of its
        Wholly Owned Restricted Subsidiaries or solely among Wholly Owned
        Restricted Subsidiaries or (b) the Company and any of its other
        Restricted Subsidiaries or solely among such other Restricted
        Subsidiaries; provided, for purposes of this clause (b), no holder (or
        Affiliate of such holder) of 10% or more of any class of Capital Stock
        of the Company or any Affiliate of the Company (other than its
        Restricted Subsidiaries) owns any Capital Stock of any such Restricted
        Subsidiary;

               (3) the payment of reasonable fees and compensation to officers
        and directors of the Company or any Restricted Subsidiary and reasonable
        indemnification arrangements entered into by the Company or any
        Restricted Subsidiary, including any issuance of securities, or other
        payments, awards or grants in cash, securities or otherwise pursuant to,
        or the funding of, employment arrangements, employee stock options and
        employee stock ownership plans approved by the Board of Directors;

                                       52
<PAGE>

               (4) any payments or other transactions pursuant to any
        tax-sharing agreement between the Company and any other Person with
        which the Company files a consolidated tax return or with which the
        Company is part of a consolidated group for tax purposes;

               (5) purchases of services from physicians, hospitals, claims
        management or processing companies, pharmacy benefit management
        companies and other health care or service providers in the ordinary
        course of business on fair and reasonable terms as determined in good
        faith by the Company;

               (6) any sale of shares of Capital Stock (other than Disqualified
        Stock) of the Company or any options, warrants or other rights to
        acquire such Capital Stock; or

               (7) any Permitted Investments or any Restricted Payments not
        prohibited by Section 4.04.

               Notwithstanding the foregoing, any transaction or series of
related transactions covered by the first paragraph of this Section 4.08 and not
covered by clauses (2) through (7) of this paragraph, (a) the aggregate amount
of which exceeds $7.5 million in value, must be approved or determined to be
fair in the manner provided for in clause (1)(A) or (B) above and (b) the
aggregate amount of which exceeds $10 million in value, must be determined to be
fair in the manner provided for in clause (1)(B) above.

               SECTION 4.09. Limitation on Liens.

               The Company will not, and will not permit any Restricted
Subsidiary to, create, incur, assume or suffer to exist any Lien on any of its
assets or properties of any character, or any shares of Capital Stock or
Indebtedness of any Restricted Subsidiary, without making effective provision
for all of the Notes and all other amounts due under this Indenture to be
directly secured equally and ratably with (or, if the obligation or liability to
be secured by such Lien is subordinated in right of payment to the Notes, prior
to) the obligation or liability secured by such Lien for so long as such
Indebtedness is secured by such Lien; provided that the Trustee shall release
any such equal and ratable or prior Lien hereunder, at such time (A) the Lien on
such assets or properties, shares or Indebtedness is released, or (B) the assets
or properties or shares subject to such Lien are sold in accordance with Section
4.11.

               The foregoing limitation does not apply to:

               (1) Liens existing on the Closing Date;

               (2) Liens granted after the Closing Date on any assets or Capital
        Stock of the Company or its Restricted Subsidiaries created in favor of
        the Holders;

               (3) Liens with respect to the assets of a Restricted Subsidiary
        granted by such Restricted Subsidiary to the Company or a Wholly Owned
        Restricted Subsidiary to secure Indebtedness owing to the Company or
        such other Restricted Subsidiary;

               (4) Liens securing Indebtedness which is Incurred to refinance
        secured Indebtedness which is permitted to be Incurred under clause (3)
        of the second paragraph

                                       53
<PAGE>

        of Section 4.03(a); provided that such Liens do not extend to, or cover
        any, property or assets of the Company or any Restricted Subsidiary
        other than the property or assets securing the Indebtedness being
        refinanced;

               (5) Liens to secure Indebtedness Incurred under clause (1) of the
        second paragraph of Section 4.03(a) and Liens to secure the 7% Senior
        Notes due 2003 incurred pursuant to Section 1009 of the indenture for
        the 7% Senior Notes due 2003;

               (6) Liens (including extensions and renewals thereof) upon real
        or personal property acquired after the Closing Date; provided that (a)
        such Lien is created solely for the purpose of securing Indebtedness
        Incurred, in accordance with Section 4.03, to finance the cost
        (including the cost of improvement, installation or construction) of the
        property or assets subject thereto and such Lien is created prior to, at
        the time of or within six months after the later of the acquisition, the
        installation, the completion of construction or the commencement of full
        operation of such property, (b) the principal amount of the Indebtedness
        secured by such Lien does not exceed 100% of such cost and (c) any such
        Lien shall not extend to or cover any property or assets other than such
        property or assets and any improvements on such item;

               (7) Liens on cash set aside at the time of the Incurrence of any
        Indebtedness, or government securities purchased with such cash, in
        either case to the extent that such cash or government securities
        pre-fund the payment of interest on such Indebtedness and are held in a
        collateral or escrow account or similar arrangement to be applied for
        such purpose; or

               (8) Permitted Liens.

               SECTION 4.10.  Limitation on Sale-Leaseback Transactions.

               The Company will not, and will not permit any Restricted
Subsidiary to, enter into any sale-leaseback transaction involving any of its
assets or properties whether now owned or hereafter acquired, whereby the
Company or a Restricted Subsidiary sells or transfers such assets or properties
and then or thereafter leases such assets or properties, or any part thereof, or
any other assets or properties which the Company or such Restricted Subsidiary,
as the case may be, intends to use for substantially the same purpose or
purposes as the assets or properties sold or transferred.

               The foregoing restriction does not apply to any sale-leaseback
transaction if:

               (1) the lease is for a period, including renewal rights, of not
        in excess of three years;

               (2) the lease secures or relates to industrial revenue or
        pollution control bonds;

               (3) the transaction is solely between the Company and any Wholly
        Owned Restricted Subsidiary or solely between Wholly Owned Restricted
        Subsidiaries; or

                                       54
<PAGE>

               (4) the Company or such Restricted Subsidiary, within 12 months
        after the sale or transfer of any assets or properties is completed,
        applies an amount not less than the Net Cash Proceeds received from such
        sale in accordance with clause (A), (B) or (C) of the third paragraph of
        Section 4.11.

               SECTION 4.11.  Limitation on Asset Sales.

               The Company will not, and will not permit any Restricted
Subsidiary to, consummate any Asset Sale, unless (1) the consideration received
by the Company or such Restricted Subsidiary is at least equal to the fair
market value of the assets sold or disposed of; provided that this clause (1)
shall not apply to any sale, transfer or other disposition arising from
foreclosure, condemnation or similar action with respect to any assets or any
dispositions required by law or regulatory authority, and (2) at least 75% of
the consideration received consists of (a) cash or Temporary Cash Investments,
(b) the assumption of unsubordinated Indebtedness or liabilities (other than
contingent liabilities and liabilities that are subordinated to the Notes or any
Subsidiary Guarantee) of the Company or any Subsidiary Guarantor or Indebtedness
or liabilities (other than contingent liabilities) of any other Restricted
Subsidiary (in each case, other than Indebtedness or liabilities owed to the
Company or any Affiliate of the Company) or (c) Replacement Assets (other than
Investments in any Person), provided that the Company, such Subsidiary Guarantor
or such other Restricted Subsidiary is irrevocably and unconditionally released
from all liability under such Indebtedness or liabilities; provided that the
Company and its Restricted Subsidiaries may receive consideration in amounts in
excess of that permitted in clause (2) (the "Excess Non-Liquid Consideration"),
to the extent that the aggregate fair market value of all Excess Non-Liquid
Consideration received by the Company and its Restricted Subsidiaries from
previous Asset Sales since the Closing Date that has not yet converted into cash
or Temporary Cash Investments does not exceed $25 million.

               For purposes of this provision, any securities, notes, mortgages
or other obligations received by the Company or any Restricted Subsidiary in any
Asset Sale that are converted, sold or exchanged by the Company or such
Restricted Subsidiary into cash within 90 days of the related Asset Sale (to the
extent of the cash received in that conversion, sale or exchange) shall be
deemed to be cash.

               In the event and to the extent that the Net Cash Proceeds
received by the Company or any of its Restricted Subsidiaries from one or more
Asset Sales occurring on or after the Closing Date in any period of 12
consecutive months exceed 10% of Adjusted Consolidated Net Tangible Assets
(determined as of the date closest to the commencement of such 12-month period
for which a consolidated balance sheet of the Company and its Subsidiaries has
been filed with the Commission or provided to the Trustee), then the Company
shall or shall cause the relevant Restricted Subsidiary to:

               (1) within twelve months after the date Net Cash Proceeds so
        received exceed 10% of Adjusted Consolidated Net Tangible Assets,

                      (A) to make capital contributions to Restricted
               Subsidiaries which are required by law or requested in writing to
               be made by the appropriate state

               regulatory authorities or retain any Net Cash Proceeds as capital
               of any Restricted Subsidiary to the extent distribution is not
               permitted by regulatory authorities,

                      (B) apply an amount equal to such excess Net Cash Proceeds
               to permanently repay unsubordinated Indebtedness of the Company
               or any Subsidiary Guarantor or Indebtedness of any other
               Restricted Subsidiary, in each case owing to a Person other than
               the Company or any Affiliate of the Company,

                      (C) invest an equal amount, or the amount not so applied
               pursuant to clause (A) (or enter into a definitive agreement
               committing to so invest within 12 months after the date of such
               agreement), in Replacement Assets, or

                      (D) any combination of prepayment or investment permitted
               by the foregoing clauses (1)(A), (1)(B) and (1)(C), and

               (2) apply (no later than the end of the 12-month period referred
        to in clause (1)) such excess Net Cash Proceeds (to the extent not
        applied pursuant to clause (1)) as provided in the following paragraphs
        of this Section 4.11.

The amount of such excess Net Cash Proceeds required to be applied (or to be
committed to be applied) during such 12-month period as set forth in clause (1)
of the preceding sentence and not applied as so required by the end of such
period shall constitute "Excess Proceeds."

               If, as of the first day of any calendar month, the aggregate
amount of Excess Proceeds not theretofore subject to an Offer to Purchase
pursuant to this Section 4.11 totals at least $15 million, the Company must
commence, not later than the fifteenth Business Day of such month, and
consummate an Offer to Purchase from the Holders (and if required by the terms
of any Indebtedness that is pari passu with the Notes ("Pari Passu
Indebtedness"), from the holders of such Pari Passu Indebtedness) on a pro rata
basis an aggregate principal amount of Notes (and Pari Passu Indebtedness) equal
to the Excess Proceeds on such date, at a purchase price equal to 100% of their
principal amount, plus, in each case, accrued interest (if any) to the Payment
Date. If any Excess Proceeds remain after consummation of an Offer to Purchase,
the Company or any Restricted Subsidiary may use such Excess Proceeds for any
purpose not otherwise prohibited by this Indenture.

               SECTION 4.12. Repurchase of Notes upon a Change of Control. The
Company shall commence, within 30 days of the occurrence of a Change of Control,
and consummate an Offer to Purchase for all Notes then outstanding, at a
purchase price equal to 101% of the principal amount thereof, plus accrued
interest, if any, to the Payment Date.

               The Company shall not be required to make an Offer to Purchase
upon the occurrence of a Change of Control, if a third party makes an offer to
purchase the Notes in the manner, at the times and price and otherwise in
compliance with the requirements of this Indenture applicable to an Offer to
Purchase for a Change of Control and purchases all Notes validly tendered and
not withdrawn in such offer to purchase.

               SECTION 4.13. Existence. Subject to Articles Four and Five of
this Indenture, the Company will do or cause to be done all things necessary to
preserve and keep in full force

                                       56
<PAGE>

and effect its existence and the existence of each of its Restricted
Subsidiaries in accordance with the respective organizational documents of the
Company and each Restricted Subsidiary and the rights (whether pursuant to
charter, partnership certificate, agreement, statute or otherwise), licenses and
franchises of the Company and each Restricted Subsidiary; provided that the
Company shall not be required to preserve any such right, license or franchise,
or the existence of any Restricted Subsidiary, if the maintenance or
preservation thereof is no longer desirable in the conduct of the business of
the Company and its Restricted Subsidiaries taken as a whole.

               SECTION 4.14. Payment of Taxes and Other Claims. The Company will
pay or discharge and shall cause each of its Subsidiaries to pay or discharge,
or cause to be paid or discharged, before the same shall become delinquent (i)
all material taxes, assessments and governmental charges levied or imposed upon
(a) the Company or any such Subsidiary, (b) the income or profits of any such
Subsidiary which is a corporation or (c) the property of the Company or any such
Subsidiary and (ii) all material lawful claims for labor, materials and supplies
that, if unpaid, might by law become a lien upon the property of the Company or
any Restricted Subsidiary; provided that the Company shall not be required to
pay or discharge, or cause to be paid or discharged, any such tax, assessment,
charge or claim the amount, applicability or validity of which is being
contested in good faith by appropriate proceedings and for which adequate
reserves have been established.

               SECTION 4.15. Maintenance of Properties and Insurance. The
Company will cause all properties used or useful in the conduct of its business
or the business of any of its Restricted Subsidiaries to be maintained and kept
in good condition, repair and working order and supplied with all necessary
equipment and will cause to be made all necessary repairs, renewals,
replacements, betterments and improvements thereof, all as in the judgment of
the Company may be necessary so that the business carried on in connection
therewith may be properly and advantageously conducted at all times; provided
that nothing in this Section 4.15 shall prevent the Company or any Restricted
Subsidiary from discontinuing the use, operation or maintenance of any of such
properties or disposing of any of them, if such discontinuance or disposal is,
in the judgment of the Company, desirable in the conduct of the business of the
Company or such Restricted Subsidiary.

               The Company will provide or cause to be provided, for itself and
its Restricted Subsidiaries, insurance (including appropriate self-insurance)
against loss or damage of the kinds customarily insured against by corporations
similarly situated and owning like properties, including, but not limited to,
products liability insurance and public liability insurance, with reputable
insurers or with the government of the United States of America, or an agency or
instrumentality thereof, in such amounts, with such deductibles and by such
methods as shall be customary for corporations similarly situated in the
industry in which the Company or any such Restricted Subsidiary, as the case may
be, is then conducting business.

               SECTION 4.16. Notice of Defaults. In the event that any Officer
becomes aware of any Default or Event of Default, the Company shall promptly
deliver to the Trustee an Officers' Certificate specifying such Default or Event
of Default.

               SECTION 4.17. Compliance Certificates. (a) The Company and each
Subsidiary Guarantor (to the extent that such Subsidiary Guarantor is required
under the Trust

                                       57
<PAGE>

Indenture Act of 1939, as amended) shall deliver to the Trustee, within 120 days
after the end of each fiscal year, an Officers' Certificate stating whether or
not the signers know of any Default or Event of Default that occurred during
such fiscal year. Such certificate shall contain a certification from the
principal executive officer, principal financial officer or principal accounting
officer of the Company that a review has been conducted of the activities of the
Company and its Restricted Subsidiaries and the Company's and its Restricted
Subsidiaries' performance under this Indenture and that the Company has complied
with all conditions and covenants under this Indenture. For purposes of this
Section 4.17, such compliance shall be determined without regard to any period
of grace or requirement of notice provided under this Indenture. If any of the
officers of the Company signing such certificate has knowledge of such a Default
or Event of Default, the certificate shall describe any such Default or Event of
Default and its status.

               (b) So long as not contrary to the then current recommendations
of the American Institute of Certified Public Accountants, the Company shall
deliver to the Trustee, within 120 days after the end of each fiscal year,
beginning with the fiscal year in which this Indenture was executed, a
certificate signed by the Company's independent certified public accountants
stating (i) that their audit examination has included a review of the terms of
this Indenture and the Notes as they relate to accounting matters, (ii) that
they have read the most recent Officers' Certificate delivered to the Trustee
pursuant to paragraph (a) of this Section 4.17 and (iii) whether, in connection
with their audit examination, anything came to their attention that caused them
to believe that the Company was not in compliance with any of the terms,
covenants, provisions or conditions of Article Four and Section 5.01 of this
Indenture as they pertain to accounting matters and, if any Default or Event of
Default has come to their attention, specifying the nature and period of
existence thereof; provided that such independent certified public accountants
shall not be liable in respect of such statement by reason of any failure to
obtain knowledge of any such Default or Event of Default that would not be
disclosed in the course of an audit examination conducted in accordance with
generally accepted auditing standards in effect at the date of such examination.

               SECTION 4.18. Commission Reports and Reports to Holders. Whether
or not the Company is then required to file reports with the Commission, the
Company shall file with the Commission all such reports and other information as
it would be required to file with the Commission by Sections 13(a) or 15(d)
under the Exchange Act if it were subject thereto. The Company shall supply the
Trustee and each Holder who so requests or shall supply to the Trustee for
forwarding to each such Holder, without cost to such Holder, copies of such
reports and other information within 15 days after the date it would have been
required to file such reports or other information with the Commission had it
been subject to such Sections. The Company also shall comply with the other
provisions of TIA Section 314(a).

               SECTION 4.19. Waiver of Stay, Extension or Usury Laws. The
Company and each of the Subsidiary Guarantors covenants (to the extent that it
may lawfully do so) that it will not at any time insist upon, or plead, or in
any manner whatsoever claim or take the benefit or advantage of, any stay or
extension law or any usury law or other law that would prohibit or forgive the
Company from paying all or any portion of the principal of, premium, if any, or
interest on the Notes as contemplated herein, wherever enacted, now or at any
time hereafter in force, or that may affect the covenants or the performance of
this Indenture; and (to the extent

                                       58
<PAGE>

that it may lawfully do so) the Company and each of the Subsidiary Guarantors
(to the extent that it may lawfully do so) hereby expressly waives all benefit
or advantage of any such law and covenants that it will not hinder, delay or
impede the execution of any power herein granted to the Trustee, but will suffer
and permit the execution of every such power as though no such law had been
enacted.

               SECTION 5.01. When Company May Merge, Etc.

               The Company will not consolidate with, merge with or into, or
sell, convey, transfer, lease or otherwise dispose of all or substantially all
of its property and assets (as an entirety or substantially an entirety in one
transaction or a series of related transactions) to, any Person or permit any
Person to merge with or into it unless:

               (1) it shall be the continuing Person, or the Person (if other
        than it) formed by such consolidation or into which it is merged or that
        acquired or leased such property and assets of (the "Surviving Person")
        shall be a corporation organized and validly existing under the laws of
        the United States of America or any jurisdiction thereof and shall
        expressly assume, by a supplemental indenture, executed and delivered to
        the Trustee, all of the Company's obligations under this Indenture and
        the Notes;

               (2) immediately after giving effect to such transaction, no
        Default or Event of Default shall have occurred and be continuing;

               (3) immediately after giving effect to such transaction on a pro

        shall have a Consolidated Net Worth equal to or greater than the
        Consolidated Net Worth of the Company immediately prior to such
        transaction;

               (4) immediately after giving effect to such transaction on a pro
        forma basis the Company, or the Surviving Person, as the case may be,
        could Incur at least $1.00 of Indebtedness under the first paragraph of
        Section 4.03(a); provided that this clause (4) shall not apply to a
        consolidation, merger or sale of all (but not less than all) of the
        assets of the Company if all Liens and Indebtedness of the Company or
        the Surviving Person, as the case may be, and its Restricted
        Subsidiaries outstanding immediately after such transaction would have
        been permitted (and all such Liens and Indebtedness, other than Liens
        and Indebtedness of the Company and its Restricted Subsidiaries
        outstanding immediately prior to the transaction, shall be deemed to
        have been Incurred) for all purposes of this Indenture;

               (5) it delivers to the Trustee an Officers' Certificate
        (attaching the arithmetic computations to demonstrate compliance with
        clauses (3) and (4)) and Opinion of Counsel, in each case stating that
        such consolidation, merger or transfer and such supplemental indenture
        complies with this provision and that all conditions precedent provided
        for herein relating to such transaction have been complied with; and

                                       59
<PAGE>

               (6) each Subsidiary Guarantor, unless such Subsidiary Guarantor
        is the Person with which the Company has entered into a transaction
        under this Section 5.01 shall have by amendment to its Note Guarantee
        confirmed that its Note Guarantee shall apply to the obligations of the
        Company or the Surviving Person in accordance with the Notes and this
        Indenture;

provided, however, that clauses (3) and (4) above do not apply if, in the good
faith determination of the Board of Directors of the Company, whose
determination shall be evidenced by a Board Resolution, the principal purpose of
such transaction is to change the state of incorporation of the Company and any
such transaction shall not have as one of its purposes the evasion of the
foregoing limitations.

               Each Subsidiary Guarantor (other than any Subsidiary Guarantor
whose Note Guarantee is to be released in accordance with the terms of its Note
Guarantee and this Indenture in connection with any transaction complying with
the provisions of Section 4.11) will not, and the Company will not cause or
permit any Subsidiary Guarantor to, consolidate with or merge with or into any
Person other than the Company or any other Subsidiary Guarantor unless:

               (1) such Subsidiary Guarantor is the surviving corporation or the
        Person formed by or surviving any such consolidation or merger (if other
        than the Subsidiary Guarantor) is a corporation organized and existing
        under the laws of the United States or any State thereof or the District
        of Columbia and such Person assumes by supplemental indenture all of the
        obligations of the Subsidiary Guarantor on its Note Guarantee;

               (2) immediately after giving effect to such transaction, no
        Default or Event of Default shall have occurred and be continuing; and

               (3) immediately after giving effect to such transaction and the
        use of any net proceeds therefrom on a pro forma basis, the Company
        could satisfy the provisions of clause (3) of the first paragraph of
        this Section 5.01.

               Any merger or consolidation of a Subsidiary Guarantor with and
into the Company (with the Company being the surviving entity) or another
Subsidiary Guarantor need only comply with clause (5) of the first paragraph of
this Section 5.01.

               SECTION 5.02. Successor Substituted. Upon any consolidation or
merger, or any sale, conveyance, transfer, lease or other disposition of all or
substantially all of the property and assets of the Company or a Subsidiary
Guarantor in accordance with Section 5.01 of this Indenture, the successor
Person formed by such consolidation or into which the Company or such Subsidiary
Guarantor is merged or to which such sale, conveyance, transfer, lease or other
disposition is made shall succeed to, and be substituted for, and may exercise
every right and power of, the Company or such Subsidiary Guarantor under this
Indenture with the same effect as if such successor Person had been named as the
Company or such Subsidiary Guarantor herein; provided that the Company shall not
be released from its obligation to pay the principal of, premium, if any, or
interest on the Notes, and a Subsidiary Guarantor shall not be released from its
Note Guarantee, in the case of a lease of all or substantially all of its

        in the aggregate for all such issues of all such Persons, whether such
        Indebtedness now exists or shall hereafter be created, (I) an event of
        default that has caused the holder thereof to declare such Indebtedness
        to be due and payable prior to its Stated Maturity and such Indebtedness
        has not been discharged in full or such acceleration has not been
        rescinded or annulled within 30 days of such acceleration and/or (II)
        the failure to make a principal payment at the final (but not any
        interim) fixed maturity and such defaulted payment shall not have been
        made, waived or extended within 30 days of such payment default;

               (f) any final judgment or order (not covered by insurance) for

        such final judgments or orders against all such Persons (treating any
        deductibles, self-insurance or retention as not so covered) shall be
        rendered against the Company, any Subsidiary Guarantor or any
        Significant Subsidiary and shall not be paid or discharged, and there
        shall be any period of 60 consecutive days following entry of the final
        judgment or order that causes the aggregate amount for all such final
        judgments or orders outstanding and not paid or discharged against all
        such Persons to exceed $35 million during which a stay of enforcement of
        such final judgment or order, by reason of a pending appeal or
        otherwise, shall not be in effect;

               (g) a court having jurisdiction in the premises enters a decree
        or order for (A) relief in respect of the Company, any Subsidiary
        Guarantor or any Significant Subsidiary in an involuntary case under any

        substantially all of the property and assets of the Company, any
        Subsidiary Guarantor or any Significant Subsidiary or (C) the winding up
        or liquidation of the affairs of the Company, any Subsidiary Guarantor
        or any Significant Subsidiary and, in each case, such decree or order
        shall remain unstayed and in effect for a period of 60 consecutive days;

        under any such law, (B) consents to the appointment of or taking
        possession by a receiver, liquidator, assignee, custodian, trustee,
        sequestrator or similar official of the Company, any Subsidiary

        reason cease to be in full force and effect.

               SECTION 6.02. Acceleration. If an Event of Default (other than an
Event of Default specified in clause (g) or (h) of Section 6.01 that occurs with
respect to the Company or any Subsidiary Guarantor) occurs and is continuing
under this Indenture, the Trustee or the Holders of at least 25% in aggregate
principal amount of the Notes then outstanding, by written notice to the Company
(and to the Trustee if such notice is given by the Holders), may, and the
Trustee at the request of such Holders shall, declare the principal of, premium,
if any, and accrued interest on the Notes to be immediately due and payable.
Upon a declaration of acceleration, such principal of, premium, if any, and
accrued interest shall be immediately due and payable. In the event of a
declaration of acceleration because an Event of Default set forth in clause (e)
of Section 6.01 has occurred and is continuing, such declaration of acceleration
shall be automatically rescinded and annulled if the event of default triggering
such Event of Default pursuant to clause (e) shall be remedied or cured by the
Company or the relevant Significant Subsidiary or waived by the holders of the
relevant Indebtedness within 60 days after the declaration of acceleration with
respect thereto. If an Event of Default specified in clause (g) or (h) of
Section 6.01 occurs with respect to the Company or any Subsidiary Guarantor, the
principal of, premium, if any, and accrued interest on the Notes then
outstanding shall ipso facto become and be immediately due and payable without
any declaration or other act on the part of the Trustee or any Holder.

               At any time after such declaration of acceleration, but before a
judgment or decree for the payment of the money due has been obtained by the
Trustee, the Holders of at least a majority in principal amount of the
outstanding Notes by written notice to the Company and to the Trustee, may waive
all past Defaults and rescind and annul a declaration of acceleration and its
consequences if (a) the Company has paid or deposited with the Trustee a sum
sufficient to pay (i) all sums paid or advanced by the Trustee hereunder and the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel, (ii) all overdue

                                       62
<PAGE>

interest on all Notes, (iii) the principal of and premium, if any, on any Notes
that have become due otherwise than by such declaration or occurrence of
acceleration and interest thereon at the rate prescribed therefore by such
Notes, and (iv) to the extent that payment of such interest is lawful, interest
upon overdue interest, if any, at the rate prescribed therefore by such Notes,
(b) all existing Events of Default, other than the non-payment of the principal
of, premium, if any, and accrued interest on the Notes that have become due
solely by such declaration of acceleration, have been cured or waived and (c)
the rescission would not conflict with any judgment or decree of a court of
competent jurisdiction.

               SECTION 6.03. Other Remedies. If an Event of Default occurs and
is continuing, the Trustee may, and at the direction of the Holders of at least
a majority in principal amount of the outstanding Notes shall, pursue any
available remedy by proceeding at law or in equity to collect the payment of
principal of, premium, if any, or interest on the Notes or to enforce the
performance of any provision of the Notes or this Indenture.

               The Trustee may maintain a proceeding even if it does not possess
any of the Notes or does not produce any of them in the proceeding.

               SECTION 6.04. Waiver of Past Defaults. Subject to Sections 6.02,
6.07 and 9.02, the Holders of at least a majority in principal amount of the
outstanding Notes, by notice to the Trustee, may waive an existing Default or
Event of Default and its consequences, except a Default in the payment of
principal of, premium, if any, or interest on any Note as specified in clause
(a) or (b) of Section 6.01 or in respect of a covenant or provision of this
Indenture which cannot be modified or amended without the consent of the Holder
of each outstanding Note affected. Upon any such waiver, such Default shall
cease to exist, and any Event of Default arising therefrom shall be deemed to
have been cured, for every purpose of this Indenture; but no such waiver shall
extend to any subsequent or other Default or Event of Default or impair any
right consequent thereto.

               SECTION 6.05. Control by Majority. The Holders of at least a
majority in aggregate principal amount of the outstanding Notes may direct the
time, method and place of conducting any proceeding for any remedy available to
the Trustee or exercising any trust or power conferred on the Trustee; provided
that the Trustee may refuse to follow any direction that conflicts with law or
this Indenture, that may involve the Trustee in personal liability, or that the
Trustee determines in good faith may be unduly prejudicial to the rights of
Holders of Notes not joining in the giving of such direction; and provided
further that the Trustee may take any other action it deems proper that is not
inconsistent with any such direction received from Holders of Notes.

               SECTION 6.06. Limitation on Suits. A Holder may not institute any
proceeding, judicial or otherwise, with respect to this Indenture or the Notes,
or for the appointment of a receiver or trustee, or for any other remedy
hereunder, unless:

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

                                       63
<PAGE>

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

               (iii) such Holder or Holders offer the Trustee indemnity
        reasonably satisfactory to the Trustee against any costs, liability or
        expense;

               (iv) the Trustee does not comply with the request within 60 days
        after receipt of the request and the offer of indemnity; and

               (v) during such 60-day period, the Holders of a majority in
        aggregate principal amount of the outstanding Notes do not give the
        Trustee a direction that is inconsistent with the request.

               For purposes of Section 6.05 of this Indenture and this Section
6.06, the Trustee shall comply with TIA Section 316(a) in making any
determination of whether the Holders of the required aggregate principal amount
of outstanding Notes have concurred in any request or direction of the Trustee
to pursue any remedy available to the Trustee or the Holders with respect to
this Indenture or the Notes or otherwise under the law.

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

               SECTION 6.07. Rights of Holders to Receive Payment.
Notwithstanding any other provision of this Indenture, the right of any Holder
of a Note to receive payment of the principal of, premium, if any, or interest
on, such Note or to bring suit for the enforcement of any such payment, on or
after the due date expressed in the Notes, shall not be impaired or affected
without the consent of such Holder.

               SECTION 6.08. Collection Suit by Trustee. If an Event of Default
in payment of principal, premium or interest specified in clause (a), (b) or (c)
of Section 6.01 occurs and is continuing, the Trustee may recover judgment in
its own name and as trustee of an express trust against the Company or any other
obligor of the Notes for the whole amount of principal, premium, if any, and
accrued interest remaining unpaid, together with interest on overdue principal,
premium, if any, and, to the extent that payment of such interest is lawful,
interest on overdue installments of interest, in each case at the rate specified
in the Notes, and such further amount as shall be sufficient to cover the costs
and expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel.

               SECTION 6.09. Trustee May File Proofs of Claim. The Trustee may
file such proofs of claim and other papers or documents as may be necessary or
advisable in order to have the claims of the Trustee (including any claim for
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 7.07) and the Holders allowed in any judicial proceedings relative to
the Company (or any other obligor of the Notes), its creditors or its property
and shall be entitled and empowered to collect and receive any monies,
securities or other property payable or deliverable upon conversion or exchange
of the Notes or upon any such claims and to distribute the same, and any
custodian, receiver, assignee, trustee, liquidator, sequestrator or other
similar

                                       64
<PAGE>

official in any such judicial proceeding is hereby authorized by each Holder to
make such payments to the Trustee and, in the event that the Trustee shall
consent to the making of such payments directly to the Holders, to pay to the
Trustee any amount due to it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 7.07. Nothing herein contained shall be
deemed to empower the Trustee to authorize or consent to, or accept or adopt on
behalf of any Holder, any plan of reorganization, arrangement, adjustment or
composition affecting the Notes or the rights of any Holder thereof, or to
authorize the Trustee to vote in respect of the claim of any Holder in any such
proceeding.

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

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

               Second: to Holders for amounts then due and unpaid for principal
of, premium, if any, and interest on the Notes in respect of which or for the
benefit of which such money has been collected, ratably, without preference or
priority of any kind, according to the amounts due and payable on such Notes for
principal, premium, if any, and interest, respectively; and

               Third: to the Company or any other obligors of the Notes, as
their interests may appear, or as a court of competent jurisdiction may direct.

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

               SECTION 6.11. Undertaking for Costs. In any suit for the
enforcement of any right or remedy under this Indenture or in any suit against
the Trustee for any action taken or omitted by it as Trustee, a court may
require any party litigant in such suit to file an undertaking to pay the costs
of the suit, and the court may assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in the suit having due regard to the
merits and good faith of the claims or defenses made by the party litigant. This
Section 6.11 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 outstanding Notes.

               SECTION 6.12. Restoration of Rights and Remedies. If the Trustee
or any Holder has instituted any proceeding to enforce any right or remedy under
this Indenture and such proceeding has been discontinued or abandoned for any
reason, or has been determined adversely to the Trustee or to such Holder, then,
and in every such case, subject to any determination in such proceeding, the
Company, the Trustee and the Holders shall be restored severally and
respectively to their former positions hereunder and thereafter all rights and
remedies of the Company, Trustee and the Holders shall continue as though no
such proceeding had been instituted.

               SECTION 6.13. Rights and Remedies Cumulative. Except as otherwise
provided with respect to the replacement or payment of mutilated, destroyed,
lost or wrongfully taken Notes in Section 2.09, no right or remedy herein
conferred upon or reserved to the Trustee or to

                                       65
<PAGE>

the Holders is intended to be exclusive of any other right or remedy, and every
right and remedy shall, to the extent permitted by law, be cumulative and in
addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

               SECTION 6.14. Delay or Omission Not Waiver. No delay or omission
of the Trustee or of any Holder to exercise any right or remedy accruing upon
any Event of Default shall impair any such right or remedy or constitute a
waiver of any such Event of Default or an acquiescence therein. Every right and
remedy given by this Article Six or by law to the Trustee or to the Holders may
be exercised from time to time, and as often as may be deemed expedient, by the
Trustee or by the Holders, as the case may be.

                                  ARTICLE SEVEN
                                     TRUSTEE

               SECTION 7.01. General. The Trustee, prior to the occurrence of an
Event of Default hereunder and after the curing or waiving of all such Events of
Default which may have occurred, undertakes to perform such duties and only such
duties as are specifically set forth in this Indenture. In case an Event of
Default hereunder has occurred (which has not been cured or waived), the Trustee
shall exercise such of the rights and powers vested in it by this Indenture, and
use the same degree of care and skill in their exercise, as a prudent man would
exercise or use under the circumstances in the conduct of his own affairs.

               No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act or its own willful misconduct, except that prior to the occurrence of an
Event of Default hereunder and after the curing or waiving of all such Events of
Default which may have occurred:

               (a) the duties and obligations of the Trustee shall be determined
        solely by the express provisions of this Indenture, and the Trustee
        shall not be liable except for the performance of such duties and
        obligations as are specifically set forth in this Indenture, and no
        implied covenants of obligations shall be read into this Indenture
        against the Trustee; and

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

               The duties and responsibilities of the Trustee shall be as
provided by the TIA and as set forth herein. Notwithstanding the foregoing, no
provision of this Indenture shall require the Trustee to expend or risk its own
funds or otherwise incur any financial liability in the performance of any of
its duties hereunder, or in the exercise of any of its rights or powers, if it

                                       66
<PAGE>

shall have reasonable grounds for believing that repayment of such funds or
adequate indemnity against such risk or liability is not reasonably assured to
it. Whether or not herein expressly so provided, 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 Article
Seven.

               SECTION 7.02. Certain Rights of Trustee. Subject to TIA Sections
315(a) through (d) and Section 7.01 of this Indenture:

               (i) the Trustee may rely, and shall be protected in acting or
        refraining from acting, upon any resolution, certificate, statement,
        instrument, opinion, report, notice, request, direction, consent, order,
        bond, debenture, note, other evidence of indebtedness or other paper or
        document believed by it to be genuine and to have been signed or
        presented by the proper person;

               (ii) before the Trustee acts or refrains from acting, it may
        require an Officers' Certificate or an Opinion of Counsel, which shall
        conform to Section 11.04. The Trustee shall not be liable for any action
        it takes or omits to take in good faith in reliance on such certificate
        or opinion;

               (iii) the Trustee may act through its attorneys and agents and
        shall not be responsible for the misconduct or negligence of any
        attorney or agent appointed with due care by it hereunder;

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

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

               (vi) whenever in the administration of this Indenture the Trustee
        shall deem it desirable that a matter be proved or established prior to
        taking, suffering or omitting any action hereunder, the Trustee (unless
        other evidence be herein specifically prescribed) may, in the absence of
        bad faith on its part, rely upon an Officers' Certificate; and

               (vii) 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, direction,
        consent, order, bond, debenture, note, other evidence of indebtedness or
        other paper or document, 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 Company personally or by agent or attorney.

                                       67
<PAGE>

               SECTION 7.03. Individual Rights of Trustee. The Trustee, in its
individual or any other capacity, may become the owner or pledgee of Notes and
may otherwise deal with the Company or its Affiliates with the same rights it
would have if it were not the Trustee. Any Agent may do the same with like
rights. However, the Trustee is subject to TIA Sections 310(b) and 311.

               SECTION 7.04. Trustee's Disclaimer. The Trustee (i) makes no
representation as to the validity or adequacy of this Indenture or the Notes,
(ii) shall not be accountable for the Company's use or application of the
proceeds from the Notes and (iii) shall not be responsible for any statement in
the Notes other than its certificate of authentication.

               SECTION 7.05. Notice of Default. If any Default or any Event of
Default occurs and is continuing and if such Default or Event of Default is
known to a Responsible Officer of the Trustee, the Trustee shall mail to each
Holder in the manner and to the extent provided in TIA Section 313(c) notice of
the Default or Event of Default within 45 days after it occurs, unless such
Default or Event of Default has been cured; provided, however, that, except in
the case of a default in the payment of the principal of, premium, if any, or
interest on any Note, the Trustee shall be protected in withholding such notice
if and so long as the board of directors, the executive committee or a trust
committee of directors and/or Responsible Officers of the Trustee in good faith
determine that the withholding of such notice is in the interest of the Holders.

               SECTION 7.06. Reports by Trustee to Holders. Within 60 days after
each May 15, beginning with May 15, 2003, the Trustee shall mail to each Holder
as provided in TIA Section 313(c) a brief report dated as of such May 15, if
required by TIA Section 313(a).

               A copy of each report at the time of its mailing to the Holders
of Securities shall be mailed to the Company and filed with the Commission and
each stock exchange on which the Securities are listed in accordance with TIA
Section 313(d). The Company shall promptly notify the Trustee when the
Securities are listed on any stock exchange or of any delisting thereof.

               SECTION 7.07. Compensation and Indemnity. The Company and the
Subsidiary Guarantors shall pay to the Trustee such compensation as shall be
agreed upon in writing for its services hereunder. The compensation of the
Trustee shall not be limited by any law on compensation of a trustee of an
express trust. The Company and the Subsidiary Guarantors shall reimburse the
Trustee upon request for all reasonable disbursements, expenses and advances
incurred or made by the Trustee without negligence or bad faith on its part.
Such expenses shall include the reasonable compensation and expenses of the
Trustee's agents and counsel.

               The Company and the Subsidiary Guarantors shall indemnify the
Trustee for, and hold it harmless against, any loss or liability or expense
incurred by it without negligence, bad faith, willful misconduct or recklessness
on its part in connection with the acceptance or administration of this
Indenture and its duties under this Indenture and the Notes, including but not
limited to the reasonable costs and expenses of defending itself against any
claim or liability and of complying with any process served upon it or any of
its officers in connection with the exercise or performance of any of its powers
or duties under this Indenture and the Notes. The Trustee shall notify the
Company and the Subsidiary Guarantors promptly of any claim for which it may
seek indemnity. Failure by the Trustee to so notify the Company shall not
relieve

                                       68
<PAGE>

the Company of its obligations hereunder, unless the Company is materially
prejudiced thereby. The Company and the Subsidiary Guarantors shall defend the
claim and the Trustee shall cooperate in the defense. Unless otherwise set forth
herein, the Trustee may have separate counsel and the Company and the Subsidiary
Guarantors shall pay the reasonable fees and expenses of such counsel. The
Company and the Subsidiary Guarantors need not pay for any settlement made
without their consent, which consent shall not be unreasonably withheld. Neither
the Company nor any Subsidiary Guarantor need reimburse any expense or indemnify
against any loss or liability incurred by the Trustee through willful
misconduct, recklessness negligence or bad faith on the part of the Trustee.

obligations in this Section 7.07, the Trustee shall have a lien prior to the
Notes on all money or property held or collected by the Trustee, in its capacity
as Trustee, except money or property held in trust to pay principal of, premium,
if any, and interest on particular Notes.

               If the Trustee incurs expenses or renders services after the
occurrence of an Event of Default specified in clause (g) or (h) of Section
6.01, the expenses and the compensation for the services will be intended to
constitute expenses of administration under Title 11 of the United States
Bankruptcy Code or any applicable federal or state law for the relief of
debtors.

               The provisions of this Section 7.07 shall survive the termination
of this Indenture.

               The Trustee shall comply with the provisions of TIA Section
313(b) to the extent applicable. The obligations of the Company and each
Subsidiary Guarantor under this Section 7.07 shall be joint and several.

               SECTION 7.08. Replacement of Trustee. A resignation or removal of
the Trustee and appointment of a successor Trustee shall become effective only
upon the successor Trustee's acceptance of appointment as provided in this
Section 7.08.

               The Trustee may resign at any time by so notifying the Company in
writing at least 30 days prior to the date of the proposed resignation. The
Holders of a majority in principal amount of the outstanding Notes may remove
the Trustee by so notifying the Trustee in writing and may appoint a successor

the office of Trustee for any reason, the Company shall promptly appoint a
successor Trustee. Within one year after the successor Trustee takes office, the
Holders of a majority in principal amount of the outstanding Notes may appoint a
successor Trustee to replace the successor Trustee appointed by the Company. If
the successor Trustee does not deliver its written acceptance required by the
next succeeding paragraph of this Section 7.08 within 30 days after the retiring
Trustee resigns or is removed, the retiring Trustee, the Company or the Holders
of a majority in principal amount of the outstanding Notes may, at the expense
of the Company, petition any court of competent jurisdiction for the appointment
of a successor Trustee.

<PAGE>

               A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Immediately after the
delivery of such written acceptance, subject to the lien provided in Section
7.07, (i) the retiring Trustee shall transfer all property held by it as Trustee
to the successor Trustee, (ii) the resignation or removal of the retiring
Trustee shall become effective and (iii) the successor Trustee shall have all
the rights, powers and duties of the Trustee under this Indenture. A successor
Trustee shall mail notice of its succession to each Holder. No successor Trustee

successor Trustee shall be qualified and eligible under this Article.

               If the Trustee is no longer eligible under Section 7.10 or shall
fail to comply with TIA Section 310(b), any Holder who satisfies the
requirements of TIA Section 310(b) may petition any court of competent
jurisdiction for the removal of the Trustee and the appointment of a successor
Trustee. If at any time the Trustee shall cease to be eligible in accordance
with the provisions of this Section 7.08, the Trustee shall resign immediately
in the manner and with the effect provided in this Section.

               The Company shall give notice of any resignation and any removal
of the Trustee and each appointment of a successor Trustee to all Holders. Each
notice shall include the name of the successor Trustee and the address of its
Corporate Trust Office.

               Notwithstanding replacement of the Trustee pursuant to this
Section 7.08, the Company's obligation under Section 7.07 shall continue for the
benefit of the retiring Trustee.

               SECTION 7.09. Successor Trustee by Merger, Etc. If the Trustee
consolidates with, merges or converts into, or transfers all or substantially
all of its corporate trust business (including the administration of the trust
created by this Indenture) to, another corporation or national banking
association, the resulting, surviving or transferee corporation or national
banking association without any further act shall be the successor Trustee with
the same effect as if the successor Trustee had been named as the Trustee
herein, provided such corporation shall be otherwise qualified and eligible
under this Article.

               SECTION 7.10. Eligibility. This Indenture shall always have a
Trustee who satisfies the requirements of TIA Section 310(a)(1). The Trustee (or
in the case of a subsidiary of a bank holding company its holding company
parent) shall have a combined capital and surplus of at least $25 million as set
forth in its most recent published annual report of condition that is subject to
the requirements of applicable Federal or state supervising or examining
authority. If at any time the Trustee shall cease to be eligible in accordance
with the provisions of this Section, the Trustee shall resign immediately in the
manner and with the effect specified in this Article.

               SECTION 7.11. Money Held in Trust. The Trustee shall not be
liable for interest on any money received by it except as the Trustee may agree
with the Company. Money held in trust by the Trustee need not be segregated from
other funds except to the extent required by law and except for money held in
trust under Article Eight of this Indenture.

        any payment referred to in this clause (y), money in an amount or (z) a
        combination thereof in an amount sufficient (in the opinion of a
        nationally recognized firm of independent public accountants expressed
        in a written certification thereof delivered to the Trustee), without
        consideration of any reinvestment of any interest thereon, to pay
        principal, premium, if, any, and interest on the Notes to maturity or
        redemption, as the case may be, and to pay all other sums payable by it
        hereunder, (C) no Default or Event of Default with respect to the Notes
        shall have occurred and be continuing on the date of such deposit, (D)
        such deposit will not result in a breach or violation of, or constitute
        a default under, this Indenture or any other agreement or instrument to
        which the Company is a party or by which it is bound and (E) the Company
        has delivered to the Trustee an Officers' Certificate and an Opinion of
        Counsel, in each case stating that all conditions precedent provided for
        herein relating to the satisfaction and discharge of this Indenture have
        been complied with.

               With respect to the foregoing clause (i), the Company's
obligations under Section 7.07 shall survive. With respect to the foregoing
clause (ii), the Company's obligations in Sections 2.02, 2.03, 2.04, 2.05, 2.06,
2.07, 2.08, 2.09, 2.14, 4.01, 4.02, 7.07, 7.08, 8.04, 8.05 and 8.06 shall
survive until the Notes are no longer outstanding. Thereafter, only the
Company's obligations in Sections 7.07, 8.04, 8.05 and 8.06 shall survive. After
any such irrevocable deposit, the Trustee upon request shall acknowledge in
writing the discharge of the Company's obligations under the Notes and this
Indenture except for those surviving obligations specified above.

               SECTION 8.02. Defeasance and Discharge of Indenture. The Company
will be deemed to have paid and will be discharged from any and all obligations
in respect of the Notes on the 91st day after the date of the deposit (or such
other applicable period of time as provided by the United States Bankruptcy Code
or the New York Debtor and Creditor Law) referred to in clause (A) of this
Section 8.02, and the provisions of this Indenture will no longer be in effect
with respect to the Notes (except for, among other matters, certain obligations
to register the

                                       71
<PAGE>

transfer or exchange of the Notes, to replace stolen, lost or mutilated Notes,
to maintain paying agencies and to hold monies for payment in trust), and the
Trustee, at the expense of the Company, shall execute proper instruments
acknowledging the same if:

               (A) with reference to this Section 8.02, the Company has
        irrevocably deposited or caused to be irrevocably deposited with the
        Trustee (or another trustee satisfying the requirements of Section 7.10)
        and conveyed all right, title and interest to the Trustee for the
        benefit of the Holders, under the terms of an irrevocable trust
        agreement in form and substance satisfactory to the Trustee as trust
        funds in trust, specifically pledged to the Trustee for the benefit of
        the Holders as security for payment of the principal of, premium, if
        any, and interest, if any, on the Notes, and dedicated solely to, the
        benefit of the Holders, in and to (1) money in an amount, (2) U.S.
        Government Obligations that, through the payment of interest, premium,
        if any, and principal in respect thereof in accordance with their terms,
        will provide, not later than one day before the due date of any payment
        referred to in this clause (A), money in an amount or (3) a combination
        thereof in an amount sufficient, in the opinion of a nationally
        recognized firm of independent public accountants expressed in a written
        certification thereof delivered to the Trustee, to pay and discharge,
        without consideration of the reinvestment of such interest and after
        payment of all federal, state and local taxes or other charges and
        assessments in respect thereof payable by the Trustee, the principal of,
        premium, if any, and interest on the outstanding Notes on the Stated
        Maturity of such principal or interest or on any earlier Redemption
        Date; provided that the Trustee shall have been irrevocably instructed
        to apply such money or the proceeds of such U.S. Government Obligations
        to the payment of such principal, premium, if any, and interest with
        respect to the Notes, and with respect to any Redemption Date, the
        Company shall have provided the Trustee with irrevocable instructions to
        redeem all Notes on such Redemption Date;

               (B) the Company has delivered to the Trustee (1) either (x) an
        Opinion of Counsel to the effect that Holders will not recognize income,
        gain or loss for federal income tax purposes as a result of the
        Company's exercise of its option under this Section 8.02 and will be
        subject to federal income tax on the same amount and in the same manner
        and at the same times as would have been the case if such option had not
        been exercised, which Opinion of Counsel shall be based upon (and
        accompanied by a copy of) a ruling of the Internal Revenue Service to
        the same effect unless there has been a change in applicable federal
        income tax law after the Closing Date such that a ruling is no longer
        required or (y) a ruling directed to the Trustee received from the
        Internal Revenue Service to the same effect as the aforementioned
        Opinion of Counsel and (2) an Opinion of Counsel to the effect that the
        creation of the defeasance trust does not violate the Investment Company
        Act of 1940 and that after the passage of 91 days (or such other
        applicable period of time as provided by the United States Bankruptcy
        Code or the New York Debtor and Creditor Law) following the deposit
        (except, with respect to any trust funds for the account of any Holder
        who may be deemed to be an "insider" for purposes of the United States
        Bankruptcy Code, after one year following the deposit), the trust funds
        will not be subject to the effect of Section 547 of the United States
        Bankruptcy Code or Section 15 of the New York Debtor and Creditor Law in
        a case commenced by or against the Company under either such statute,
        and either (I) the trust funds will no

                                       72
<PAGE>

        longer remain the property of the Company (and therefore will not be
        subject to the effect of any applicable bankruptcy, insolvency,
        reorganization or similar laws affecting creditors' rights generally) or
        (II) if a court were to rule under any such law in any case or
        proceeding that the trust funds remained property of the Company, (a)
        assuming such trust funds remained in the possession of the Trustee
        prior to such court ruling to the extent not paid to the Holders, the
        Trustee will hold, for the benefit of the Holders, a valid and perfected
        security interest in such trust funds that is not avoidable in
        bankruptcy or otherwise except for the effect of Section 552(b) of the
        United States Bankruptcy Code on interest on the trust funds accruing
        after the commencement of a case under such statute and (b) the Holders
        will be entitled to receive adequate protection of their interests in
        such trust funds if such trust funds are used in such case or
        proceeding;

               (C) immediately after giving effect to such deposit, on a pro
        forma basis, no Default or Event of Default shall have occurred and be
        continuing on the date of such deposit or during the period ending on
        the 91st day after such date of such deposit (or such other applicable
        period of time as provided by the United States Bankruptcy Code or the
        New York Debtor and Creditor Law), and such deposit shall not result in
        a breach or violation of, or constitute a default under, this Indenture
        or any other agreement or instrument to which the Company or any of its
        Subsidiaries is a party or by which the Company or any of its
        Subsidiaries is bound;

               (D) if the Notes are then listed on a national securities
        exchange, the Company has delivered to the Trustee an Opinion of Counsel
        to the effect that the Notes will not be delisted as a result of such
        deposit, defeasance and discharge; and

               (E) the Company has delivered to the Trustee an Officers'
        Certificate and an Opinion of Counsel, in each case stating that all
        conditions precedent provided for herein relating to the defeasance
        contemplated by this Section 8.02 have been complied with.

               Notwithstanding the foregoing, prior to the end of the 91-day (or
one year) period referred to in clause (B)(2) of this Section 8.02, none of the
Company's obligations under this Indenture shall be discharged. Subsequent to
the end of such 91-day (or one year) period with respect to this Section 8.02,
the Company's obligations in Sections 2.02, 2.03, 2.04, 2.05, 2.06, 2.07, 2.08,
2.09, 2.14, 4.01, 4.02, 8.04, 8.05, 8.06 and the rights, powers, trusts, duties
and immunities of the Trustee hereunder shall survive until the Notes are no
longer outstanding. Thereafter, only the Company's obligations in Sections 7.07,
8.04, 8.05 and 8.06 shall survive. If and when a ruling from the Internal
Revenue Service or an Opinion of Counsel referred to in clause (B)(1) of this
Section 8.02 is able to be provided specifically without regard to, and not in
reliance upon, the continuance of the Company's obligations under Section 4.01,
then the Company's obligations under such Section 4.01 shall cease upon delivery
to the Trustee of such ruling or Opinion of Counsel and compliance with the
other conditions precedent provided for herein relating to the defeasance
contemplated by this Section 8.02.

               After any such irrevocable deposit, the Trustee upon request
shall acknowledge in writing the discharge of the Company's obligations under
the Notes and this Indenture except for those surviving obligations in the
immediately preceding paragraph.

               SECTION 8.03. Defeasance of Certain Obligations. The Company may
omit to comply with any term, provision or condition set forth in clauses (3)
and (4) of Section 5.01 and Sections 4.03 through 4.18 and clause (c) of Section
6.01 with respect to clauses (3) and (4) of Section 5.01, clause (d) of Section
6.01 with respect to Sections 4.03 through 4.18 and clauses (e) and (f) of
Section 6.01 shall be deemed not to be Events of Default in each case with
respect to the outstanding Notes if:

               (i) with reference to this Section 8.03, the Company has
        irrevocably deposited or caused to be irrevocably deposited with the
        Trustee (or another trustee satisfying the requirements of Section 7.10)
        and conveyed all right, title and interest to the Trustee for the
        benefit of the Holders, under the terms of an irrevocable trust
        agreement in form and substance satisfactory to the Trustee as trust
        funds in trust, specifically pledged to the Trustee for the benefit of
        the Holders as security for payment of the principal of, premium, if
        any, and interest, if any, on the Notes, and dedicated solely to, the
        benefit of the Holders, in and to (A) money in an amount, (B) U.S.
        Government Obligations that, through the payment of interest, premium,
        if any, and principal in respect thereof in accordance with their terms,
        will provide, not later than one day before the due date of any payment
        referred to in this clause (i), money in an amount or (C) a combination
        thereof in an amount sufficient, in the opinion of a nationally
        recognized firm of independent public accountants expressed in a written
        certification thereof delivered to the Trustee, to pay and discharge,
        without consideration of the reinvestment of such interest and after
        payment of all federal, state and local taxes or other charges and
        assessments in respect thereof payable by the Trustee, the principal of,
        premium, if any, and interest on the outstanding Notes on the Stated
        Maturity of such principal or interest or on any earlier Redemption
        Date; provided that the Trustee shall have been irrevocably instructed
        to apply such money or the proceeds of such U.S. Government Obligations
        to the payment of such principal, premium, if any, and interest with
        respect to the Notes, and with respect to any Redemption Date, the
        Company shall have provided the Trustee with irrevocable instructions to
        redeem all Notes on such Redemption Date;

               (ii) the Company has delivered to the Trustee an Opinion of
        Counsel to the effect that (A) the creation of the defeasance trust does
        not violate the Investment Company Act of 1940, (B) after the passage of
        91 days (or such other applicable period of time as provided by the
        United States Bankruptcy Code or the New York Debtor and Creditor Law)
        following the deposit (except, with respect to any trust funds for the
        account of any Holder who may be deemed to be an "insider" for purposes
        of the United States Bankruptcy Code, after one year following the
        deposit), the trust funds will not be subject to the effect of Section
        547 of the United States Bankruptcy Code or Section 15 of the New York
        Debtor and Creditor Law in a case commenced by or against the Company
        under either such statute, and either (1) the trust funds will no longer
        remain the property of the Company (and therefore will not be subject to
        the effect of any applicable bankruptcy, insolvency, reorganization or
        similar laws affecting creditors' rights generally) or (2) if a court
        were to rule under any such law in any case or proceeding that the trust
        funds remained property of the Company, (x) assuming such trust funds
        remained in the possession of the Trustee prior to such court ruling to
        the extent not paid to the Holders, the Trustee will hold, for the
        benefit of the Holders, a valid

                                       74
<PAGE>

        and perfected security interest in such trust funds that is not
        avoidable in bankruptcy or otherwise (except for the effect of Section
        552(b) of the United States Bankruptcy Code on interest on the trust
        funds accruing after the commencement of a case under such statute) and
        (y) the Holders will be entitled to receive adequate protection of their
        interests in such trust funds if such trust funds are used in such case
        or proceeding, (C) the Holders will not recognize income, gain or loss
        for federal income tax purposes as a result of such deposit and
        defeasance of certain covenants and Events of Default and will be
        subject to federal income tax on the same amount and in the same manner
        and at the same times as would have been the case if such deposit and
        defeasance had not occurred and (D) the Trustee, for the benefit of the
        Holders, has a valid first-priority security interest in the trust
        funds;

               (iii) immediately after giving effect to such deposit on a pro
        forma basis, no Default or Event of Default shall have occurred and be
        continuing on the date of such deposit or during the period ending on
        the 91st day after such date of such deposit (or such other applicable
        period of time as provided by the United States Bankruptcy Code or the
        New York Debtor and Creditor Law), and such deposit shall not result in
        a breach or violation of, or constitute a default under, this Indenture
        or any other agreement or instrument to which the Company or any of its
        Subsidiaries is a party or by which the Company or any of its
        Subsidiaries is bound;

               (iv) if the Notes are then listed on a national securities
        exchange, the Company has delivered to the Trustee an Opinion of Counsel
        to the effect that the Notes will not be delisted as a result of such
        deposit, defeasance and discharge; and

               (v) the Company has delivered to the Trustee an Officers'
        Certificate and an Opinion of Counsel, in each case stating that all
        conditions precedent provided for herein relating to the defeasance
        contemplated by this Section 8.03 have been complied with.

               SECTION 8.04. Defeasance and Certain Other Events of Default. In
the event the Company exercises its option to omit compliance with certain
covenants and provisions of this Indenture with respect to the Notes as
described in Section 8.03 and the Notes are declared due and payable because of
the occurrence of an Event of Default that remains applicable, the amount of
money and/or U.S. Government Obligations on deposit with the Trustee will be
sufficient to pay amounts due on the Notes at the time of their Stated Maturity
or any earlier Redemption Date, but may not be sufficient to pay amounts due on
the Notes at the time of the acceleration resulting from such Event of Default.
However, the Company will remain liable for such payments and any Subsidiary
Note Guarantor's Note Guarantee with respect to such payments will remain in
effect.

               SECTION 8.05. Application of Trust Money. Subject to Section
8.07, the Trustee or Paying Agent shall hold in trust money or U.S. Government
Obligations deposited with it pursuant to Section 8.01, 8.02, 8.03 or 8.04, as
the case may be, and shall apply the deposited money and the money from U.S.
Government Obligations in accordance with the Notes and this Indenture to the
payment of principal of, premium, if any, and interest on the Notes; but such
money need not be segregated from other funds except to the extent required by
law.

                                       75
<PAGE>

               SECTION 8.06. Repayment to Company. Subject to Sections 7.07,
8.01, 8.02, 8.03 and 8.04, the Trustee and the Paying Agent shall promptly pay
to the Company upon request set forth in an Officers' Certificate any excess
money held by them at any time and thereupon shall be relieved from all
liability with respect to such money. The Trustee and the Paying Agent shall pay
to the Company upon request any money held by them for the payment of principal,
premium, if any, or interest that remains unclaimed for two years; provided that
the Trustee or Paying Agent before being required to make any payment may cause
to be published at the expense of the Company once in a newspaper of general
circulation in The City of New York or mail to each Holder entitled to such
money at such Holder's address (as set forth in the Security Register) notice
that such money remains unclaimed and that after a date specified therein (which
shall be at least 30 days from the date of such publication or mailing) any
unclaimed balance of such money then remaining will be repaid to the Company.
After payment to the Company, Holders entitled to such money must look to the
Company for payment as general creditors unless an applicable law designates
another Person, and all liability of the Trustee and such Paying Agent with
respect to such money shall cease.

               SECTION 8.07. Reinstatement. If the Trustee or Paying Agent is
unable to apply any money or U.S. Government Obligations in accordance with
Section 8.01, 8.02, 8.03 or 8.04, as the case may be, by reason of any legal
proceeding or by reason of any order or judgment of any court or governmental
authority enjoining, restraining or otherwise prohibiting such application, the
Company's obligations under this Indenture and the Notes shall be revived and
reinstated as though no deposit had occurred pursuant to Section 8.01, 8.02,
8.03 or 8.04, as the case may be, until such time as the Trustee or Paying Agent
is permitted to apply all such money or U.S. Government Obligations in
accordance with Section 8.01, 8.02, 8.03 or 8.04, as the case may be; provided
that, if the Company has made any payment of principal of, premium, if any, or
interest on any Notes because of the reinstatement of its obligations, the
Company shall be subrogated to the rights of the Holders of such Notes to
receive such payment from the money or U.S. Government Obligations held by the
Trustee or Paying Agent.

                                  ARTICLE NINE
                       AMENDMENTS, SUPPLEMENTS AND WAIVERS

               SECTION 9.01. Without Consent of Holders. The Company, when
authorized by a resolution of its Board of Directors (as evidenced by a Board
Resolution delivered to the Trustee), the Subsidiary Guarantors and the Trustee
may amend or supplement this Indenture, the Note Guarantees or the Notes without
notice to or the consent of any Holder:

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

               (2) to comply with Section 4.07 and Article Five of this
        Indenture;

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

               (4) to evidence and provide for the acceptance of appointment
        hereunder by a successor Trustee; or

                                       76
<PAGE>

               (5) to make any change that, in the good faith opinion of the
        Board of Directors as evidenced by a Board Resolution, does not
        materially and adversely affect the rights of any Holder.

               SECTION 9.02. With Consent of Holders. Subject to Sections 6.04
and 6.07 and without prior notice to the Holders, the Company, the Subsidiary
Guarantors when authorized by its Board of Directors (as evidenced by a Board
Resolution delivered to the Trustee), and the Trustee may amend this Indenture,
the Note Guarantees and the Notes with the written consent of the Holders of a
majority in aggregate principal amount of the Notes then outstanding, and the
Holders of a majority in aggregate principal amount of the Notes then
outstanding by written notice to the Trustee may waive future compliance by the
Company with any provision of this Indenture, the Note Guarantees or the Notes.

               Notwithstanding the provisions of this Section 9.02, without the
consent of each Holder affected, an amendment or waiver, including a waiver
pursuant to Section 6.04, may not:

               (1) change the Stated Maturity of the principal of, or any
        installment of interest on, any Note;

               (2) reduce the principal amount of, premium, if any, or interest
        on any Note;

               (3) change the optional redemption dates or optional redemption
        prices of the Notes from that stated in Section 3.01;

               (4) change any place or currency of payment of principal of,
        premium, if any, or interest on, any Note;

               (5) impair the right to institute suit for the enforcement of any
        payment on or after the Stated Maturity (or, in the case of redemption,
        on or after the Redemption Date) on any Note;

               (6) reduce the percentage or aggregate principal amount of
        outstanding Notes the consent of whose Holders is necessary to modify or
        amend this Indenture or to waive compliance with certain provisions of
        or certain Defaults under this Indenture;

               (7) release any Subsidiary Guarantor from its Note Guarantee,
        other than in accordance with the terms of this Indenture;

               (8) waive a default in the payment of principal of, premium, if
        any, or interest on, any Note; or

               (9) modify any of the provisions of this Section 9.02, except to
        increase any such percentage or to provide that certain other provisions
        of this Indenture cannot be modified or waived without the consent of
        the Holder of each outstanding Note affected thereby.

                                       77
<PAGE>

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

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

               SECTION 9.03. Revocation and Effect of Consent. Until an
amendment or waiver becomes effective, a consent to it by a Holder is a
continuing consent by the Holder and every subsequent Holder of a Note or
portion of a Note that evidences the same debt as the Note of the consenting
Holder, even if notation of the consent is not made on any Note. However, any
such Holder or subsequent Holder may revoke the consent as to its Note or
portion of its Note. Such revocation shall be effective only if the Trustee
receives the notice of revocation before the date the amendment, supplement or
waiver becomes effective. An amendment, supplement or waiver shall become
effective on receipt by the Trustee of written consents from the Holders of the
requisite percentage in principal amount of the outstanding Notes.

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

               After an amendment, supplement or waiver becomes effective, it
shall bind every Holder unless it is of the type described in the second
paragraph of Section 9.02. In case of an amendment or waiver of the type
described in the second paragraph of Section 9.02, the amendment or waiver shall
bind each Holder who has consented to it and every subsequent Holder of a Note
that evidences the same indebtedness as the Note of the consenting Holder.

               SECTION 9.04. Notation on or Exchange of Notes. If an amendment,
supplement or waiver changes the terms of a Note, the Trustee may require the
Holder to deliver such Note to the Trustee. At the Company's expense, the
Trustee may place an appropriate notation on the Note about the changed terms
and return it to the Holder and the Trustee may place an appropriate notation on
any Note thereafter authenticated. Alternatively, if the Company or the Trustee
so determines, the Company in exchange for the Note shall issue and the Trustee
shall authenticate a new Note that reflects the changed terms. Failure to make
the appropriate notation, or issue a new Note, shall not affect the validity and
effect of such amendment, supplement or waiver.

               SECTION 9.05. Trustee to Sign Amendments, Etc. The Trustee shall
be entitled to receive, and shall be fully protected in relying upon, an Opinion
of Counsel stating that the

                                       78
<PAGE>

execution of any amendment, supplement or waiver authorized pursuant to this
Article Nine is authorized or permitted by this Indenture and that it will be
valid and binding upon the Company. Subject to the preceding sentence, the
Trustee shall sign such amendment, supplement or waiver if the same does not
adversely affect the rights, duties, liabilities or immunities of the Trustee.
The Trustee may, but shall not be obligated to, execute any such amendment,
supplement or waiver that affects the Trustee's own rights, duties or immunities
under this Indenture or otherwise.

               SECTION 9.06. Conformity with Trust Indenture Act. Every
supplemental indenture executed pursuant to this Article Nine shall conform to
the requirements of the TIA as then in effect.

                                   ARTICLE TEN
                                 NOTE GUARANTEES

               SECTION 10.01.  Note Guarantees.

               Subject to this Article Ten, each of the Subsidiary Guarantors
hereby, jointly and severally, unconditionally guarantees to each Holder of a
Note authenticated and delivered by the Trustee and to the Trustee and its
successors and assigns, irrespective of the validity and enforceability of this
Indenture, the Notes or the obligations of the Company hereunder or thereunder,
that: (a) the principal of, premium, if any, and interest on the Notes will be
promptly paid in full when due, whether at maturity, by acceleration, redemption
or otherwise, and interest on the overdue principal of, premium, if any, and
interest on the Notes, if any, if lawful, and all other obligations of the
Company to the Holders or the Trustee hereunder or thereunder will be promptly
paid in full or performed, all in accordance with the terms hereof and thereof;
and (b) in case of any extension of time of payment or renewal of any Notes or
any of such other obligations, that same will be promptly paid in full when due
or performed in accordance with the terms of the extension or renewal, whether
at stated maturity, by acceleration or otherwise. Failing payment when due of
any amount so guaranteed or any performance so guaranteed for whatever reason,
the Subsidiary Guarantors shall be jointly and severally obligated to pay the
same immediately. Each Subsidiary Guarantor agrees that this is a guarantee of
payment and not a guarantee of collection.

               The Subsidiary Guarantors hereby agree that their obligations
hereunder shall be unconditional, irrespective of the validity, regularity or
enforceability of the Notes or this Indenture, the absence of any action to
enforce the same, any waiver or consent by any Holder of the Notes with respect
to any provisions hereof or thereof, the recovery of any judgment against the
Company, any action to enforce the same or any other circumstance which might
otherwise constitute a legal or equitable discharge or defense of a guarantor.
Each Subsidiary Guarantor hereby waives diligence, presentment, demand of
payment, filing of claims with a court in the event of insolvency or bankruptcy
of the Company, any right to require a proceeding first against the Company,
protest, notice and all demands whatsoever and covenant that the Note Guarantee
shall not be discharged except by complete performance of the obligations
contained in the Notes and this Indenture or pursuant to Section 10.03.

                                       79
<PAGE>

               If any Holder or the Trustee is required by any court or
otherwise to return to the Company, the Subsidiary Guarantors or any custodian,
trustee, liquidator or other similar official acting in relation to either the
Company or the Subsidiary Guarantors, any amount paid by either to the Trustee
or such Holder, the Note Guarantee, to the extent theretofore discharged, shall
be reinstated in full force and effect.

               Each Subsidiary Guarantor agrees that it shall not be entitled to
any right of subrogation in relation to the Holders in respect of any
obligations guaranteed hereby until payment in full of all obligations
guaranteed hereby. Each Subsidiary Guarantor further agrees that, as between the
Subsidiary Guarantors, on the one hand, and the Holders and the Trustee, on the
other hand, (x) the maturity of the obligations guaranteed hereby may be
accelerated as provided in Article Six for the purposes of the Note Guarantee,
notwithstanding any stay, injunction or other prohibition preventing such
acceleration in respect of the obligations guaranteed hereby, and (y) in the
event of any declaration of acceleration of such obligations as provided in
Article Six, such obligations (whether or not due and payable) shall forthwith
become due and payable by the Subsidiary Guarantors for the purpose of the Note
Guarantee. The Subsidiary Guarantors shall have the right to seek contribution
from any non-paying Subsidiary Guarantor so long as the exercise of such right
does not impair the rights of the Holders under the Note Guarantee.

        SECTION 10.02. Limitation on Subsidiary Guarantor Liability.

               Each Subsidiary Guarantor, and by its acceptance of Notes, each
Holder, hereby confirms that it is the intention of all such parties that the
Note Guarantee of such Subsidiary Guarantor not constitute a fraudulent transfer
or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance
Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to
the extent applicable to any Note Guarantee. To effectuate the foregoing
intention, the Trustee, the Holders and the Subsidiary Guarantors hereby
irrevocably agree that the obligations of such Subsidiary Guarantor under its
Note Guarantee under this Article Ten shall be limited to the maximum amount as
will, after giving effect to such maximum amount and all other contingent and
fixed liabilities of such Subsidiary Guarantor that are relevant under such
laws, and after giving effect to any collections from, rights to receive
contribution from or payments made by or on behalf of any other Subsidiary
Guarantor in respect of the obligations of such other Subsidiary Guarantor under
this Article Ten, result in the obligations of such Subsidiary Guarantor under
its Note Guarantee not constituting a fraudulent transfer or conveyance.

        SECTION 10.03. Releases Following Certain Events.

               The Note Guarantee issued by any Subsidiary Guarantor will be
automatically and unconditionally released and discharged upon (1) any sale,
exchange or transfer to any Person (other than an Affiliate of the Company) of
all of the Capital Stock of such Subsidiary Guarantor or all or substantially
all the assets of, such Subsidiary Guarantor, (2) any distribution or transfer
of all of the Capital Stock of such Subsidiary Guarantor to the stockholders of
the Company in compliance with Section 4.04 of this Indenture, or (3) the
designation of such Subsidiary Guarantor as an Unrestricted Subsidiary, in each
case, in accordance with the terms of this Indenture.

                                       80
<PAGE>

               Upon delivery by the Company to the Trustee of an Officers'
Certificate and an Opinion of Counsel to the effect that such sale or other
disposition was made by the Company in accordance with the applicable provisions
of this Indenture, including without limitation Section 4.11, the Trustee shall
execute any documents reasonably required in order to evidence the release of
any Subsidiary Guarantor from its obligations under its Note Guarantee.

               Any Subsidiary Guarantor not released from its obligations under
its Note Guarantee shall remain liable for the full amount of principal of and
interest on the Notes and for the other obligations of any Subsidiary Guarantor
under this Indenture as provided in this Article Ten.

                                 ARTICLE ELEVEN
                                  MISCELLANEOUS

               SECTION 11.01. Trust Indenture Act of 1939. Prior to the
effectiveness of the Registration Statement, this Indenture shall incorporate
and be governed by the provisions of the TIA that are required to be part of and
to govern indentures qualified under the TIA. After the effectiveness of the
Registration Statement, this Indenture shall be subject to the provisions of the
TIA that are required to be a part of this Indenture and shall, to the extent
applicable, be governed by such provisions.

               SECTION 11.02. Notices. Any notice or communication shall be
sufficiently given if in writing and delivered in person, mailed by first-class
mail or sent by telecopier transmission addressed as follows:

<PAGE>

               The Company, or any Subsidiary Guarantor or the Trustee by notice
to the other may designate additional or different addresses for subsequent
notices or communications.

               Any notice or communication mailed to a Holder shall be mailed to
it at its address as it appears on the Security Register by first-class mail and
shall be sufficiently given to him if so mailed within the time prescribed. Any
notice or communication shall also be so mailed to any Person described in TIA
Section 313(c), to the extent required by the TIA. Copies of any such
communication or notice to a Holder shall also be mailed to the Trustee and each
Agent at the same time.

               Failure to mail a notice or communication to a Holder as provided
herein or any defect in any such notice or communication shall not affect its
sufficiency with respect to other Holders. Except for a notice to the Trustee,
which is deemed given only when received, and except as otherwise provided in
this Indenture, if a notice or communication is mailed in the manner provided in
this Section 11.02, it is duly given, whether or not the addressee receives it.

               Where this Indenture provides for notice in any manner, such
notice may be waived in writing by the Person entitled to receive such notice,
either before or after the event, and such waiver shall be the equivalent of
such notice. Waivers of notice by Holders shall be filed with the Trustee, but
such filing shall not be a condition precedent to the validity of any action
taken in reliance upon such waiver.

               In case by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice by mail,
then such notification as shall be made with the approval of the Trustee shall
constitute a sufficient notification for every purpose hereunder.

               Holders may communicate pursuant to TIA Section 312(b) with other
Holders with respect to their rights under this Indenture or the Notes. The
Company, the Trustee, the Registrar and anyone else shall have the protection of
TIA Section 312(c).

               SECTION 11.03. Certificate and Opinion as to Conditions
Precedent. Upon any request or application by the Company to the Trustee to take
any action under this Indenture, the Company shall furnish to the Trustee:

               (i) an Officers' Certificate stating that, in the opinion of the
        signers, all conditions precedent, if any, provided for in this
        Indenture relating to the proposed action have been complied with; and

               (ii) an Opinion of Counsel stating that, in the opinion of such
        Counsel, all such conditions precedent have been complied with.

               SECTION 11.04. Statements Required in Certificate or Opinion.
Each certificate or opinion with respect to compliance with a condition or
covenant provided for in this Indenture shall include:

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

                                       82
<PAGE>

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

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

               (iv) a statement as to whether or not, in the opinion of each
        such person, such condition or covenant has been complied with;
        provided, however, that, with respect to matters of fact, an Opinion of
        Counsel may rely on an Officers' Certificate or certificates of public
        officials.

               SECTION 11.05. Rules by Trustee, Paying Agent or Registrar. The
Trustee may make reasonable rules for action by or at a meeting of Holders. The
Paying Agent or Registrar may make reasonable rules for its functions.

               SECTION 11.06. Payment Date Other Than a Business Day. If an
Interest Payment Date, Redemption Date, Payment Date, Stated Maturity or date of
maturity of any Note shall not be a Business Day, then payment of principal of,
premium, if any, or interest on such Note, as the case may be, need not be made
on such date, but may be made on the next succeeding Business Day with the same
force and effect as if made on the Interest Payment Date, Payment Date or
Redemption Date, or at the Stated Maturity or date of maturity of such Note;
provided that no interest shall accrue for the period from and after such
Interest Payment Date, Payment Date, Redemption Date, Stated Maturity or date of
maturity, as the case may be.

               SECTION 11.07. No Personal Liability of Directors, Officers,
Employees and Stockholders. No past, present or future director, officer,
employee, incorporator or stockholder of the Company or any Subsidiary
Guarantor, as such, shall have any liability for any obligations of the Company
or such Subsidiary Guarantor under the Notes, the Note Guarantees, this
Indenture or for any claim based on, in respect of, or by reason of, such
obligations or their creation. Each Holder by accepting a Note waives and
releases all such liability. The waiver and release are part of the
consideration for issuance of the Notes.

               SECTION 11.08. Governing Law. This Indenture, the Note Guarantees
and the Notes shall be governed by the laws of the State of New York. The
Trustee, the Company, the Subsidiary Guarantors and the Holders agree to submit
to the jurisdiction of the courts of the State of New York in any action or
proceeding arising out of or relating to this Indenture or the Notes.

               SECTION 11.09. No Adverse Interpretation of Other Agreements.
This Indenture may not be used to interpret another indenture, loan or debt
agreement of the Company or any Subsidiary of the Company. Any such indenture,
loan or debt agreement may not be used to interpret this Indenture.

               SECTION 11.10. No Recourse Against Others. No recourse for the
payment of the principal of, premium, if any, or interest on any of the Notes,
or for any claim based thereon

                                       83
<PAGE>

or otherwise in respect thereof, and no recourse under or upon any obligation,
covenant or agreement of the Company or any Subsidiary Guarantor contained in
this Indenture or in any of the Notes, or because of the creation of any
Indebtedness represented thereby, shall be had against any incorporator or
against any past, present or future partner, stockholder, other equity holder,
officer, director, employee or controlling person, as such, of the Company, any
Subsidiary Guarantor or of any successor Person of the Company or such
Subsidiary Guarantor, either directly or through the Company or any successor
Person of the Company or such Subsidiary Guarantor, whether by virtue of any
constitution, statute or rule of law, or by the enforcement of any assessment or
penalty or otherwise; it being expressly understood that all such liability is
hereby expressly waived and released as a condition of, and as a consideration
for, the execution of this Indenture and the issue of the Notes.

               SECTION 11.11. Successors. All agreements of the Company in this
Indenture and the Notes shall bind its successors. All agreements of the Trustee
in this Indenture shall bind its successor.

               SECTION 11.12. Duplicate Originals. The parties may sign any
number of copies of this Indenture. Each signed copy shall be an original, but
all of them together represent the same agreement.

               SECTION 11.13. Separability. In case any provision in this
Indenture or in the Notes shall be invalid, illegal or unenforceable, the
validity, legality and enforceability of the remaining provisions shall not in
any way be affected or impaired thereby.

               SECTION 11.14. Table of Contents, Headings, Etc. The Table of
Contents, Cross-Reference Table and headings of the Articles and Sections of
this Indenture have been inserted for convenience of reference only, are not to
be considered a part hereof and shall in no way modify or restrict any of the
terms and provisions hereof.

                          10 3/4% Senior Note due 2009

1.  Principal and Interest.

               The Company will pay the principal of this Note on June 1, 2009.

               The Company promises to pay interest on the principal amount of
this Note on each Interest Payment Date, as set forth below, at the rate per
annum shown above except as provided below.

               Interest will be payable semiannually (to the holders of record
of the Notes at the close of business on the May 15 or November 15 immediately
preceding the Interest Payment Date) on each Interest Payment Date, commencing
December 1, 2002.

               If an exchange offer (the "Exchange Offer") registered under the
Securities Act is not consummated and a shelf registration statement (the "Shelf
Registration Statement") under the Securities Act with respect to resales of the
Notes is not declared effective by the Commission, on or before February 21,
2003 in accordance with the terms of the Registration Rights Agreement dated May
21, 2002 between the Company, the Initial Subsidiary Guarantors and Morgan
Stanley & Co. Incorporated and UBS Warburg LLC, the annual interest rate borne
by the Notes shall be increased by 0.5% from the rate shown above accruing from
February 21, 2003 payable in cash semiannually, in arrears, on each Interest
Payment Date, commencing June 1, 2003 until the Exchange Offer is consummated, a
shelf registration statement under the Securities Act with respect to resales of
the Notes is declared effective by the Commission in accordance with the terms
of the Registration Rights Agreement or the Notes become freely tradeable
without registration under the Securities Act. The Holder of this Note is
entitled to the benefits of such Registration Rights Agreement.

               Interest on the Notes will accrue from the most recent date to
which interest has been paid or, if no interest has been paid, from May 21,
2002; provided that, if there is no existing default in the payment of interest
and this Note is authenticated between a Regular Record Date referred to on the
face hereof and the next succeeding Interest Payment Date, interest shall accrue
from such Interest Payment Date. Interest will be computed on the basis of a
360-day year of twelve 30-day months.

               The Company shall pay interest on overdue principal and premium,
if any, and interest on overdue installments of interest, to the extent lawful,
at a rate per annum that is __% in excess of the rate otherwise payable.

principal amount of the Notes as provided above on each June 1 and December 1,
commencing December 1, 2002 to the persons who are Holders (as reflected in the
Security Register at the close of business on the May 15 or November 15
immediately preceding the Interest Payment Date), in each case, even if the Note
is cancelled on registration of transfer or registration of exchange after such
record date; provided that, with respect to the payment of principal, the
Company will make payment to the Holder that surrenders this Note to a Paying
Agent on or after June 1, 2009.

               The Company will pay principal, premium, if any, and as provided
above, interest in money of the United States that at the time of payment is
legal tender for payment of public and private debts. The Company shall pay
principal, premium, if any, and interest by wire transfer to any Holder who has
provided the Company with wire transfer instructions. The Company may pay
principal, premium, if any, and interest by check to any other Holder. It may
mail an interest check to a Holder's registered address (as reflected in the
Security Register). If a payment date is a date other than a Business Day at a
place of payment, payment may be made at that place on the next succeeding day
that is a Business Day and no interest shall accrue for the intervening period.

3.  Paying Agent and Registrar.

               Initially, the Trustee will act as authenticating agent, Paying
Agent and Registrar. The Company may change any authenticating agent, Paying
Agent or Registrar without notice. The Company, any Subsidiary or any Affiliate
of any of them may act as Paying Agent, Registrar or co-Registrar.

4.  Indenture; Limitations.

               The Company issued the Notes under an Indenture dated as of May

To the extent permitted by applicable law, in the event of any inconsistency
between the terms of this Note and the terms of the Indenture, the terms of the
Indenture shall control.

               The Notes are general unsecured obligations of the Company.

               The Company's obligations under the Notes are fully and
unconditionally guaranteed on an unsecured unsubordinated basis, to the extent
set forth in the Indenture, by each of the Subsidiary Guarantors.

               The Company may, subject to Article Four of the Indenture and

the aggregate principal amount of Notes originally issued on the Closing Date
remains outstanding after each such redemption and (ii) notice of such
redemption shall be mailed within 60 days of each such sale of Capital Stock.

               At any time on or prior to June 1, 2006, the Notes may be
redeemed, in whole but not in part, at the option of the Company upon the
occurrence of a Change of Control (but in no event more than 90 days after the
occurrence of such Change of Control) at a redemption price equal to 100% of the
principal amount thereof plus the Applicable Premium as of, and accrued and
unpaid interest, to, the Redemption Date.

               Notes in original denominations larger than $1,000 may be

Notes or portions of Notes called for redemption, unless the Company defaults in
the payment of the Redemption Price.

appears in the Security Register. Notes in original denominations larger than
$1,000 may be sold to the Company in part. On and

of $1,000 of principal amount and multiples of $1,000 in excess thereof. A
Holder may register the transfer or exchange of Notes in accordance with the
Indenture. The Registrar may require a Holder, among other things, to furnish
appropriate endorsements and transfer documents and to pay any taxes and fees
required by law or permitted by the Indenture. The Registrar need not register

register the transfer or exchange of any Notes for a period of 15 days before
the day of mailing of a notice of redemption of Notes selected for redemption.

8.  Persons Deemed Owners.

               A Holder shall be treated as the owner of a Note for all
purposes.

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