                                JOINDER AGREEMENT

      JOINDER AGREEMENT dated as of November 25, 2002, by the undersigned, Lamar
Pinnacle Acquisition Co., (the "Additional Subsidiary Guarantor"), in favor of
JP Morgan Chase Bank, formerly The Chase Manhattan Bank, as administrative agent
for the Lenders party to the Credit Agreement referred to below (in such
capacity, together with its successors in such capacity, the "Administrative
Agent").

      Lamar Media Corp. (formerly Lamar Advertising Company), a Delaware
corporation (the "Borrower"), and certain of its subsidiaries (collectively, the
"Existing Subsidiary Guarantors" and, together with the Borrower, the "Securing
Parties") are parties to a Credit Agreement dated August 13, 1999 (as modified
and supplemented and in effect from time to time, the "Credit Agreement",
providing, subject to the terms and conditions thereof, for extensions of credit
(by means of loans and letters of credit) to be made by the lenders therein
(collectively, together with any entity that becomes a "Lender" party to the
Credit Agreement after the date hereof as provided therein, the "Lenders" and,
together with Administrative Agent and any successors or assigns of any of the
foregoing, the "Secured Parties") to the Borrower in an aggregate principal or
face amount not exceeding $1,000,000,000 (which, in the circumstances
contemplated by Section 2.01(d) thereof, may be increased to $1,400,000,000). In
addition, the Borrower may from time to time be obligated to one or more of the
Lenders under the Credit Agreement in respect of Hedging Agreements under and as
defined in the Credit Agreement (collectively, the "Hedging Agreements").

      In connection with the Credit Agreement, the Borrower, the Existing
Subsidiary Guarantors and the Administrative Agent are parties to the Pledge
Agreement dated September 15, 1999 (the "Pledge Agreement") pursuant to which
the Securing Parties have, inter alia, granted a security interest in the
Collateral (as defined in the Pledge Agreement) as collateral security for the
Secured Obligations (as so defined). Terms defined in the Pledge Agreement are
used herein as defined therein.

      To induce the Secured Parties to enter into the Credit Agreement, and to
extend credit thereunder and to extend credit to the Borrower under Hedging
Agreements, and for other good and valuable consideration the receipt and
sufficiency of which are hereby acknowledged, the Additional Subsidiary
Guarantor has agreed to become a party to the Credit Agreement and the Pledge
Agreement as a "Subsidiary Guarantor" thereunder, and to pledge and grant a
security interest in the Collateral (as defined in the Pledge Agreement).

      Accordingly, the parties hereto agree as follows:

become a "Subsidiary Guarantor" under and for all purposes of the Credit
Agreement and the Pledge Agreement with all the rights and obligations of a

            of all Guaranteed Obligations in the same manner and to the same
            extent as is provided in Article III of the Credit Agreement;

                  (ii) pledges and grants the security interests in all right,

            Collateral (as defined in the Pledge Agreement) now owned or
            hereafter acquired by the Additional Subsidiary Guarantor and
            whether now existing or hereafter coming into existence provided for
            by Article III of the Pledge Agreement as collateral security for
            the Secured Obligations and agrees that Annex 1 thereof shall be
            supplemented as provided in Appendix A hereto;

                  (iii) makes the representations and warranties set forth in
            Article IV of the Credit Agreement and in Article II of the Pledge
            Agreement, to the extent relating to the Additional Subsidiary
            Guarantor or to the Pledged Equity evidenced by the certificates, if
            any, identified in Appendix A hereto; and

            Agreement.

         Section 103.      Compliance Certificates and Opinions.

                  Upon any application or request by the Company to the Trustee
to take any action under any provision of this Indenture, the Company and any
Guarantor (if applicable) and any

                                       - -
<PAGE>
other obligor on the Securities (if applicable) shall furnish to the Trustee an
Officers' Certificate in a form and substance reasonably acceptable to the
Trustee stating that all conditions precedent, if any, provided for in this
Indenture (including any covenant, compliance with which constitutes a condition
precedent) relating to the proposed action have been complied with, and an
Opinion of Counsel in a form and substance reasonably acceptable to the Trustee
stating that in the opinion of such counsel all such conditions precedent, if
any, have been complied with, except that, in the case of any such application
or request as to which the furnishing of such certificates or opinions is
specifically required by any provision of this Indenture relating to such
particular application or request, no additional certificate or opinion need be
furnished.

                  Every certificate or Opinion of Counsel with respect to
compliance with a condition or covenant provided for in this Indenture shall
include:

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

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

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

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

         Section 104.      Form of Documents Delivered to Trustee.

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

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

                                       - -
<PAGE>
delivered to the Trustee may have qualifications customary for opinions of the
type required and counsel delivering such Opinions of Counsel may rely on
certificates of the Company or government or other officials customary for
opinions of the type required, including certificates certifying as to matters
of fact, including that various financial covenants have been complied with.

                  Any certificate or opinion of an officer of the Company, any
Guarantor or other obligor on the Securities may be based, insofar as it relates
to accounting matters, upon a certificate or opinion of, or representations by,
an accountant or firm of accountants in the employ of the Company, unless such
officer knows, or in the exercise of reasonable care should know, that the
certificate or opinion or representations with respect to the accounting matters
upon which his certificate or opinion may be based are erroneous. Any
certificate or opinion of any independent firm of public accountants filed with
the Trustee shall contain a statement that such firm is independent with respect
to the Company.

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

         Section 105.      Acts of Holders.

                  (a)      Any request, demand, authorization, direction,
notice, consent, waiver or other action provided by this Indenture to be given
or taken by Holders may be embodied in and evidenced by one or more instruments
of substantially similar tenor signed by such Holders in person or by an agent
duly appointed in writing; and, except as herein otherwise expressly provided,
such action shall become effective when such instrument or instruments are
delivered to the Trustee and, where it is hereby expressly required, to the
Company. Such instrument or instruments (and the action embodied therein and
evidenced thereby) are herein sometimes referred to as the "Act" of the Holders
signing such instrument or instruments. Proof of execution of any such
instrument or of a writing appointing any such agent shall be sufficient for any
purpose of this Indenture and conclusive in favor of the Trustee and the
Company, if made in the manner provided in this Section 105.

                  (b)      The ownership of Securities shall be proved by the
Security Register.

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

                  (d)      The fact and date of the execution by any Person of
any such instrument or writing may be proved by the affidavit of a witness of
such execution or by a certificate of a notary public or other officer
authorized by law to take acknowledgments of deeds, certifying that the
individual signing such instrument or writing acknowledged to him the execution
thereof. Where such execution is by a signer acting in a capacity other than his
individual

                                       - -
<PAGE>
capacity, such certificate or affidavit shall also constitute sufficient proof
of his authority. The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved
in any other manner which the Trustee deems sufficient.

                  (e)      If the Company shall solicit from the Holders any
request, demand, authorization, direction, notice, consent, waiver or other Act,
the Company may, at its option, by or pursuant to a Board Resolution, fix in
advance a record date for the determination of such Holders entitled to give
such request, demand, authorization, direction, notice, consent, waiver or other
Act, but the Company shall have no obligation to do so. Notwithstanding Trust
Indenture Act Section 316(c), any such record date shall be the record date
specified in or pursuant to such Board Resolution, which shall be a date not
more than 30 days prior to the first solicitation of Holders generally in
connection therewith and no later than the date such first solicitation is
completed.

                  If such a record date is fixed, such request, demand,
authorization, direction, notice, consent, waiver or other Act may be given
before or after such record date, but only the Holders of record at the close of
business on such record date shall be deemed to be Holders for purposes of
determining whether Holders of the requisite proportion of Securities then
Outstanding have authorized or agreed or consented to such request, demand,
authorization, direction, notice, consent, waiver or other Act, and for this
purpose the Securities then Outstanding shall be computed as of such record
date; provided that no such request, demand, authorization, direction, notice,
consent, waiver or other Act by the Holders on such record date shall be deemed
effective unless it shall become effective pursuant to the provisions of this
Indenture not later than six months after such record date.

                  (f)      For purposes of this Indenture, any action by the
Holders which may be taken in writing may be taken by electronic means or as
otherwise reasonably acceptable to the Trustee.

         Section 106.      Notices, etc., to the Trustee, the Company and
any Guarantor.

                  Any request, demand, authorization, direction, notice,
consent, waiver or Act of Holders or other document provided or permitted by
this Indenture to be made upon, given or furnished to, or filed with:

                  (a)      the Trustee by any Holder or by the Company or any
Guarantor or any other obligor on the Securities shall be sufficient for every
purpose (except as provided in Section 501(c)) hereunder if in writing and
mailed, first-class postage prepaid, or delivered by recognized overnight
courier, to or with the Trustee at its Corporate Trust Office, Attention:
Corporate Trust Department, or at any other address previously furnished in
writing to the Holders or the Company, any Guarantor or any other obligor on the
Securities by the Trustee; or

                  (b)      the Company or any Guarantor by the Trustee or any
Holder shall be sufficient for every purpose (except as provided in Section
501(c)) hereunder if in writing and mailed, first-class postage prepaid, or
delivered by recognized overnight courier, to the Company or such Guarantor
addressed to it c/o PerkinElmer, Inc., 45 William Street, Wellesley,

                                       - -
<PAGE>
Massachusetts, 02481-4078, Attention: General Counsel, or at any other address
previously furnished in writing to the Trustee by the Company or such Guarantor.

         Section 107.      Notice to Holders; Waiver.

                  Where this Indenture provides for notice to Holders of any
event, such notice shall be sufficiently given (unless otherwise herein
expressly provided) if in writing and mailed, first-class postage prepaid, or
delivered by recognized overnight courier, to each Holder affected by such
event, at its address as it appears in the Security Register, not later than the
latest date, and not earlier than the earliest date, prescribed for the giving
of such notice. In any case where notice to Holders is given by mail, neither
the failure to mail such notice, nor any defect in any notice so mailed, to any
particular Holder shall affect the sufficiency of such notice with respect to
other Holders. Any notice when mailed to a Holder in the aforesaid manner shall
be conclusively deemed to have been received by such Holder whether or not
actually received by such Holder. 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 mail notice of any
event as required by any provision of this Indenture, then any method of giving
such notice as shall be reasonably satisfactory to the Trustee shall be deemed
to be a sufficient giving of such notice.

         Section 108.      Conflict with Trust Indenture Act.

                  If any provision hereof limits, qualifies or conflicts with
any provision of the Trust Indenture Act or another provision which is required
or deemed to be included in this Indenture by any of the provisions of the Trust
Indenture Act, the provision or requirement of the Trust Indenture Act shall
control. If any provision of this Indenture modifies or excludes any provision
of the Trust Indenture Act that may be so modified or excluded, the latter
provision shall be deemed to apply to this Indenture as so modified or to be
excluded, as the case may be.

         Section 109.      Effect of Headings and Table of Contents.

                  The Article and Section headings herein and the Table of
Contents are for convenience only and shall not affect the construction hereof.

         Section 110.      Successors and Assigns.

                  Except as otherwise provided in Sections 801, 802 or 1013
herein, all covenants and agreements in this Indenture by the Company and the
Guarantors shall bind their respective successors and assigns, whether so
expressed or not.

         Section 111.      Separability Clause.

                  In case any provision in this Indenture or in the Securities
or Guarantees 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 112.      Benefits of Indenture.

                  Nothing in this Indenture or in the Securities or Guarantees,
express or implied, shall give to any Person (other than the parties hereto and
their successors hereunder, any Paying Agent and the Holders) any benefit or any
legal or equitable right, remedy or claim under this Indenture.

         Section 113.      GOVERNING LAW.

                  THIS INDENTURE, THE SECURITIES AND THE GUARANTEES SHALL BE
GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW
YORK, WITHOUT GIVING EFFECT TO THE CONFLICTS OF LAWS PRINCIPLES THEREOF.

         Section 114.      Legal Holidays.

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

         Section 115.      Independence of Covenants.

                  All covenants and agreements in this Indenture shall be given
independent effect so that if a particular action or condition is not permitted
by any such covenants, the fact that it would be permitted by an exception to,
or be otherwise within the limitations of, another covenant shall not avoid the
occurrence of a Default or an Event of Default if such action is taken or
condition exists.

         Section 116.      Schedules and Exhibits.

                  All schedules and exhibits attached hereto are by this
reference made a part hereof with the same effect as if herein set forth in
full.

         Section 117.      Counterparts.

                  This Indenture may be executed in any number of counterparts,
each of which shall be deemed an original; but all such counterparts shall
together constitute but one and the same instrument.

         Section 118.      No Personal Liability of Directors, Officers,
Employees or Stockholders.

                  No director, officer, employee, member or stockholder of the
Company or any Guarantor, as such, will have any liability for any obligations
of the Company or the Guarantors under the Securities, this Indenture, the
Guarantees, or for any claim based on, in respect of, or by reason of, such
obligations or their creation. Each holder of Securities by accepting a Security
waives and releases all such liability. The waiver and release are part of the
consideration for issuance of the Securities.

                                 SECURITY FORMS

         Section 201.      Forms Generally.

                  The Securities, the Guarantees and the Trustee's certificate
of authentication thereon shall be in substantially the forms set forth in this
Article Two, with such appropriate insertions, omissions, substitutions and
other variations as are required or permitted hereby and may have such letters,
numbers or other marks of identification and such legends or endorsements placed
thereon as may be required to comply with the rules of any securities exchange,
any organizational document or governing instrument or applicable law or as may,
consistently herewith, be determined by the officers executing such Securities
and Guarantees, as evidenced by their execution of the Securities and
Guarantees. Any portion of the text of any Security may be set forth on the
reverse thereof, with an appropriate reference thereto on the face of the

                  PerkinElmer, Inc., a Massachusetts corporation (herein called
the "Company," which term includes any successor Person under the Indenture
hereinafter referred to), for value received, hereby promises to pay to Cede &
Co., or registered assigns, the principal sum of __________ United States
dollars on January 15, 2013, at the office or agency of the Company referred to
below, and to pay interest thereon from December 26, 2002, or from the most
recent Interest Payment Date to which interest has been paid or duly provided
for, semiannually on January 15th and July 15th in each year, commencing July
15, 2003 at the rate of 8 7/8% per annum, in United States dollars, until the
principal hereof is paid or duly provided for. Interest shall be computed on the
basis of a 360-day year comprised of twelve 30-day months.

                  The Holder of this Series A Security is entitled to the
benefits of the Registration Rights Agreement among the Company, the Guarantors
and the Initial Purchasers pursuant to which, subject to the terms and
conditions thereof, the Company and the Guarantors are obligated to consummate
the Exchange Offer pursuant to which the Holder of this Security (and the
related Guarantees) shall have the right to exchange this Security (and the
related Guarantees) for 8 7/8% Senior Subordinated Notes due 2013, Series B and
related guarantees (herein called the "Series B Securities") in like principal
amount as provided therein. In addition, the Company and the Guarantors have
agreed to use their reasonable best efforts to register the Securities for
resale under the Securities Act through a Shelf Registration Statement under
certain circumstances. The Series A Securities and the Series B Securities are
together (including related Guarantees) referred to as the "Securities." The
Series A Securities rank pari passu in right of payment with the Series B
Securities.

                  In the event that (a) the Exchange Offer Registration
Statement is not filed with the Commission on or prior to the 105th calendar day
following the date of original issue of the Series A Securities, (b) the
Exchange Offer Registration Statement has not been declared effective on or
prior to the 195th calendar day following the date of original issue of the
Series A Securities, (c) the Exchange Offer is not consummated on or prior to
the 240th calendar day following the date of original issue of the Series A
Securities, (d) a Shelf Registration Statement required to be filed is not
declared effective on or prior to 240 days after the original issue of the
Securities or (e) the Shelf Registration Statement is declared effective but
shall thereafter become unusable for more than 30 days in the aggregate in any
twelve month period (each such event referred to in clauses (a) through (e)
above, a "Registration Default"), liquidated damages will accrue on the
principal amount of the Series A Securities from and including the date any such
Registration Default occurs through the date on which such event is cured, at
which point the liquidated damages will cease to accrue. The liquidated damages
will accrue at a rate of 0.25% per annum during the 90-day period immediately
following the occurrence of the event giving

                                       - -
<PAGE>
rise to the liquidated damages and will increase by 0.25% per annum during each
subsequent 90-day period, but in no event will the rate exceed 1.0% per annum;
provided, however, that, if after any such liquidated damages cease to accrue, a
different event specified in clause (a), (b), (c), (d) or (e) above occurs,
liquidated damages again shall accrue pursuant to the foregoing provisions.

                  The interest so payable, and punctually paid or duly provided
for, on any Interest Payment Date will, as provided in such Indenture, be paid
to the Person in whose name this Security (or any Predecessor Securities) is
registered at the close of business on the Regular Record Date for such
interest, which shall be the January lst or July lst (whether or not a Business
Day), as the case may be, next preceding such Interest Payment Date. Any such
interest not so punctually paid, or duly provided for, and interest on such
defaulted interest at the interest rate borne by the Series A Securities, to the
extent lawful, shall forthwith cease to be payable to the Holder on such Regular
Record Date, and may either be paid to the Person in whose name this Security
(or any Predecessor Securities) is registered at the close of business on a
Special Record Date for the payment of such defaulted interest to be fixed by
the Trustee, notice whereof shall be given to Holders of Securities not less
than 10 days prior to such Special Record Date, or be paid at any time in any
other lawful manner not inconsistent with the requirements of any securities
exchange on which the Securities may be listed, and upon such notice as may be
required by the Indenture not inconsistent with the requirements of such
exchange, all as more fully provided in the Indenture.

                  Payment of the principal of, premium, if any, and interest on,
this Security, and exchange or transfer of the Security, will be made at the
Corporate Trust Office or at such other office or agency as may be maintained
for such purpose, in such coin or currency of the United States of America as at
the time of payment is legal tender for payment of public and private debts;
provided, however, that payment of interest may be made at the option of the
Company by check mailed to the address of the Person entitled thereto as such
address shall appear on the Security Register.

                  Reference is hereby made to the further provisions of this
Security set forth on the reverse hereof, which further provisions shall for all
purposes have the same effect as if set forth at this place.

                  This Security is entitled to the benefits of the Guarantees by
the Guarantors of the punctual payment when due and performance of the Indenture
Obligations made in favor of the Trustee for the benefit of the Holders.
Reference is made to Article Fourteen of the Indenture for a statement of the
respective rights, limitations of rights, duties and obligations under the
Guarantees of the Guarantors.

                  Unless the certificate of authentication hereon has been duly
executed by the Trustee referred to on the reverse hereof or by the
authenticating agent appointed as provided in the Indenture by manual signature
of an authorized signer, this Security shall not be entitled to any benefit
under the Indenture, or be valid or obligatory for any purpose.

                  IN WITNESS WHEREOF, the Company has caused this instrument to
be duly executed by the manual or facsimile signature of its authorized
officers.

               8 7/8% SENIOR SUBORDINATED NOTE DUE 2013, SERIES B

                                                         CUSIP NO.______________

No._______________                                       $______________________

                  PerkinElmer, Inc., a Massachusetts corporation (herein called
the "Company," which term includes any successor Person under the Indenture
hereinafter referred to), for value received, hereby promises to pay to Cede &
Co. or registered assigns, the principal sum of __________ United States dollars
on January 15, 2013, at the office or agency of the Company referred to below,
and to pay interest thereon from December 26, 2002, or from the most recent
Interest Payment Date to which interest has been paid or duly provided for,
semiannually on January 15th and July 15th in each year, commencing July 15,
2003 at the rate of 8 7/8% per annum, in United States dollars, until the
principal hereof is paid or duly provided for; provided that to the extent
interest has not been paid or duly provided for with respect to the Series A
Security exchanged for this Series B Security, interest on this Series B
Security shall accrue from the most recent Interest Payment Date to which
interest on the Series A Security which was exchanged for this Series B Security
has been paid or duly provided for. Interest shall be computed on the basis of a
360-day year comprised of twelve 30-day months.

                  This Series B Security was issued pursuant to the Exchange
Offer pursuant to which the 8 7/8% Senior Subordinated Notes due 2013, Series A,
and related Guarantees (herein called the "Series A Securities") in like
principal amount were exchanged for the Series B Securities and related
Guarantees. The Series B Securities rank pari passu in right of payment with the
Series A Securities.

                  For any period in which the Series A Security exchanged for
this Series B Security was outstanding, in the event that (a) the Exchange Offer
Registration Statement shall not have been filed with the Commission on or prior
to the 105th calendar day following the date of original issue of the Series A
Securities, (b) the Exchange Offer Registration Statement shall not have been
declared effective on or prior to the 195th calendar day following the date of
original issue of the Series A Securities, (c) the Exchange Offer shall not have
been consummated on or prior to the 240th calendar day following the date of
original issue of the Series A Securities, (d) a Shelf Registration Statement
required to have been filed shall not have been declared effective on or prior
to 240 days after the original issue of the Securities or (e) the Shelf
Registration Statement shall have been declared effective but thereafter shall
have become unusable for more than 30 days in the aggregate in any twelve month
period (each such event referred to in clauses (a) through (e) above, a
"Registration Default"), liquidated damages will accrue on the principal amount
of the Series A Securities from and including the date any such Registration
Default occurs through the date on which such event is cured, at which point the
liquidated damages will cease to accrue. The liquidated damages will accrue at a
rate of 0.25% per annum during the 90-day period immediately following the
occurrence of the event giving rise to the liquidated damages and will increase
by 0.25% per annum during each subsequent

                                       - -
<PAGE>
90-day period, but in no event will the rate exceed 1.0% per annum; provided,
however, that, if after any such liquidated damages cease to accrue, a different
event specified in clause (a), (b), (c), (d) or (e) above occurs, liquidated
damages again shall accrue pursuant to the foregoing provisions.

                  The interest so payable, and punctually paid or duly provided
for, on any Interest Payment Date will, as provided in such Indenture, be paid
to the Person in whose name this Security (or any Predecessor Securities) is
registered at the close of business on the Regular Record Date for such
interest, which shall be the January lst or July 1st (whether or not a Business
Day), as the case may be, next preceding such Interest Payment Date. Any such
interest not so punctually paid, or duly provided for, and interest on such
defaulted interest at the interest rate borne by the Series B Securities, to the
extent lawful, shall forthwith cease to be payable to the Holder on such Regular
Record Date, and may either be paid to the Person in whose name this Security
(or any Predecessor Securities) is registered at the close of business on a
Special Record Date for the payment of such defaulted interest to be fixed by
the Trustee, notice whereof shall be given to Holders of Securities not less
than 10 days prior to such Special Record Date, or be paid at any time in any
other lawful manner not inconsistent with the requirements of any securities
exchange on which the Securities may be listed, and upon such notice as may be
required by such exchange, all as more fully provided in the Indenture.

                  Payment of the principal of, premium, if any, and interest on,
this Security, and exchange or transfer of the Security, will be made at the
Corporate Trust Office or at such other office or agency as may be maintained
for such purpose, in such coin or currency of the United States of America as at
the time of payment is legal tender for payment of public and private debts;
provided, however, that payment of interest may be made at the option of the
Company by check mailed to the address of the Person entitled thereto as such
address shall appear on the Security Register.

                  Reference is hereby made to the further provisions of this
Security set forth on the reverse hereof, which further provisions shall for all
purposes have the same effect as if set forth at this place.

                  This Security is entitled to the benefits of the Guarantees by
the Guarantors of the punctual payment when due and performance of the Indenture
Obligations made in favor of the Trustee for the benefit of the Holders.
Reference is made to Article Fourteen of the Indenture for a statement of the
respective rights, limitations of rights, duties and obligations under the
Guarantees of the Guarantors.

                  Unless the certificate of authentication hereon has been duly
executed by the Trustee referred to on the reverse hereof or by the
authenticating agent appointed as provided in the Indenture by manual signature
of an authorized signer, this Security shall not be entitled to any benefit
under the Indenture, or be valid or obligatory for any purpose.

                  IN WITNESS WHEREOF, the Company has caused this instrument to
be duly executed by the manual or facsimile signature of its authorized
officers.

         Section 203.      Form of Reverse of securities.

                  (a)      The form of the reverse of the Series A Securities
shall be substantially as follows:

                               PERKINELMER, INC.

               8 7/8% Senior Subordinated Note due 2013, Series A

                  This Security is one of a duly authorized issue of Securities
of the Company designated as its 8 7/8% Senior Subordinated Notes due 2013,
Series A (herein called the "Securities"), initially limited (except as
otherwise provided in the Indenture referred to below) in aggregate principal
amount to $_________________ , issued under and subject to the terms of an
indenture (herein called the "Indenture") dated as of December 26, 2002, among
the Company, the Guarantors and State Street Bank and Trust Company, as trustee
(herein called the "Trustee," which term includes any successor trustee under
the Indenture), to which Indenture and all indentures supplemental thereto
reference is hereby made for a statement of the respective rights, limitations
of rights, duties, obligations and immunities thereunder of the Company, the
Guarantors, the Trustee and the Holders of the Securities, and of the terms upon
which the Securities are, and are to be, authenticated and delivered.

                  The Company may, from time to time, without notice to or the
consent of the Holders of the Securities, create and issue Additional Securities
under the Indenture ranking equally with the Initial Securities in all respects
(or in all respects other than the payment of interest accruing prior to the
issue date of such Additional Securities or except for the first payment of
interest following the issue date of such Additional Securities), subject to the
limitations described in Section 1008 of the Indenture. Such Additional
Securities will be consolidated and form a single series with the Initial
Securities and have the same terms as to status, redemption or otherwise as the
Initial Securities.

                  The Securities are subject to redemption at any time on or
after January 15, 2008, at the option of the Company, in whole or in part, on
not less than 30 nor more than 60 days' prior notice, in amounts of $1,000 or an
integral multiple thereof, at the following redemption prices (expressed as
percentages of the principal amount), if redeemed during the 12-month period
beginning January 15th of the years indicated below:

<TABLE>
<CAPTION>
                    Redemption
Year                  Price
-----               ----------
<S>                 <C>
2008                104.438%
2009                102.958%
2010                101.479%
</TABLE>

and thereafter at 100% of the principal amount, in each case, together with
accrued and unpaid interest, if any, to the Redemption Date (subject to the
rights of Holders of record on relevant record dates to receive interest due on
an Interest Payment Date).

                                       - -
<PAGE>
                  In addition, at any time prior to January 15, 2006, the
Company, at its option, may use the net proceeds of one or more Public Equity
Offerings to redeem up to an aggregate of 35% of the aggregate principal amount
of Securities issued under the Indenture (including the principal amount of any
Additional Securities issued under the Indenture) at a redemption price equal to
108.875% of the aggregate principal amount thereof, plus accrued and unpaid
interest thereon, if any, to the Redemption Date; provided that at least 65% of
the aggregate principal amount of Securities (including the principal amount of
any Additional Securities issued under the Indenture) remains outstanding
immediately after the occurrence of such redemption. In order to effect the
foregoing redemption, the Company must mail a notice of redemption no later than
30 days after the closing of the related Public Equity Offering and must
consummate such redemption within 60 days of the closing of the Public Equity
Offering.

                  If less than all of the Securities are to be redeemed, the
Trustee shall select the Securities or portions thereof to be redeemed in
compliance with the requirements of the principal national securities exchange,
if any, on which the Securities are listed, or if the Securities are not so
listed, pro rata, by lot or by any other method the Trustee shall deem fair and
reasonable. Securities redeemed in part must be redeemed only in integral
multiples of $1,000. Redemption pursuant to the provisions relating to a Public
Equity Offering must be made on a pro rata basis or on as nearly a pro rata
basis as practicable (subject to the procedures of DTC or any other depositary).

                  Upon the occurrence of a Change of Control, each Holder may
require the Company to purchase such Holder's Securities in whole or in part in
integral multiples of $1,000, at a purchase price in cash in an amount equal to
101% of the principal amount thereof, plus accrued and unpaid interest, if any,
to the date of purchase, pursuant to a Change of Control Offer in accordance
with the procedures set forth in the Indenture.

                  Under certain circumstances described in the Indenture, the
Company will be required to apply the proceeds of Asset Sales to the repayment
of the Securities and Pari Passu Indebtedness.

                  In the case of any redemption or repurchase of Securities in
accordance with the Indenture, interest installments whose Stated Maturity is on
or prior to the Redemption Date will be payable to the Holders of such
Securities of record as of the close of business on the relevant Regular Record
Date or Special Record Date referred to on the face hereof. Securities (or
portions thereof) for whose redemption and payment provision is made in
accordance with the Indenture shall cease to bear interest from and after the
Redemption Date.

                  In the event of redemption or repurchase of this Security in
accordance with the Indenture in part only, a new Security or Securities for the
unredeemed portion hereof shall be issued in the name of the Holder hereof upon
the cancellation hereof.

                  If an Event of Default shall occur and be continuing, the
principal amount of all the Securities may be declared due and payable in the
manner and with the effect provided in the Indenture.

                                       - -
<PAGE>
                  The Indenture contains provisions for defeasance at any time
of (a) the entire Indebtedness on the Securities and (b) certain restrictive
covenants and related Defaults and Events of Default, in each case upon
compliance with certain conditions set forth therein.

                  The Indenture permits, with certain exceptions (including
certain amendments permitted without the consent of any Holders and certain
amendments which require the consent of all the Holders) as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Company and the Guarantors and the rights of the Holders under the Indenture and
the Securities and the Guarantees at any time by the Company and the Trustee
with the consent of the Holders of at least a majority in aggregate principal
amount of the Securities at the time Outstanding. The Indenture also contains
provisions permitting, with certain exceptions (including certain waivers which
require the consent of all of the Holders) as therein provided, the Holders of
at least a majority in aggregate principal amount of the Securities at the time
Outstanding, on behalf of the Holders of all the Securities, to waive compliance
by the Company and the Guarantors with certain provisions of the Indenture and
the Securities and the Guarantees and certain past Defaults under the Indenture
and the Securities and the Guarantees and their consequences. Any such consent
or waiver by or on behalf of the Holder of this Security shall be conclusive and
binding upon such Holder and upon all future Holders of this Security and of any
Security issued upon the registration of transfer hereof or in exchange herefor
or in lieu hereof whether or not notation of such consent or waiver is made upon
this Security.

                  The Securities are, to the extent and manner provided in
Article Thirteen of the Indenture, subordinated and subject in right of payment
to the prior payment in full in cash (or in any other form as acceptable to the
holders of Senior Indebtedness) of all Senior Indebtedness.

                  No reference herein to the Indenture and no provision of this
Security or of the Indenture shall alter or impair the obligation of the
Company, any Guarantor or any other obligor on the Securities (in the event such
Guarantor or such other obligor is obligated to make payments in respect of the
Securities), which is absolute and unconditional, to pay the principal of,
premium, if any, and interest on, this Security at the times, place, and rate,
and in the coin or currency, herein prescribed.

                  As provided in the Indenture and subject to certain
limitations therein set forth, the transfer of this Security is registrable in
the Security Register, upon surrender of this Security for registration of
transfer at the Corporate Trust Office or the office or agency of the Company in
the Borough of Manhattan, The City of New York, duly endorsed by, or accompanied
by a written instrument of transfer in form satisfactory to the Company and the
Security Registrar duly executed by, the Holder hereof or its attorney duly
authorized in writing, and thereupon one or more new Securities, of authorized
denominations and for the same aggregate principal amount, will be issued to the
designated transferee or transferees.

                  Certificated securities shall be transferred to all beneficial
holders in exchange for their beneficial interests in the Rule 144A Global
Securities or the Regulation S Global Securities if (i) such Depositary (A) has
notified the Company that it is unwilling or unable to continue as Depositary
for such Global Security or (B) has ceased to be a clearing agency registered as
such under the Exchange Act, and in either case the Company fails to appoint a

                                       - -
<PAGE>
successor Depositary within 90 days, (ii) the Company, at its option, notifies
the Trustee in writing that it elects to cause the issuance of the Securities in
certificated form or (iii) there shall have occurred and be continuing an Event
of Default with respect to such Global Security. Upon any such issuance, the
Trustee is required to register such certificated Series A Securities in the
name of, and cause the same to be delivered to, such Person or Persons (or the
nominee of any thereof). All such certificated Series A Securities would be
required to include the Private Placement Legend.

                  Series A Securities in certificated form are issuable only in
registered form without coupons in denominations of $1,000 and any integral
multiple thereof. As provided in the Indenture and subject to certain
limitations therein set forth, the Series A Securities are exchangeable for a
like aggregate principal amount of Securities of a differing authorized
denomination, as requested by the Holder surrendering the same.

                  At any time when the Company is not subject to Sections 13 or
15(d) of the Exchange Act, upon the written request of a Holder of a Series A
Security, the Company will promptly furnish or cause to be furnished such
information as is specified pursuant to Rule 144A(d)(4) under the Securities Act
(or any successor provision thereto) to such Holder or to a prospective
purchaser of such Series A Security who such Holder informs the Company is
reasonably believed to be a "Qualified Institutional Buyer" within the meaning
of Rule 144A under the Securities Act, as the case may be, in order to permit
compliance by such Holder with Rule 144A under the Securities Act.

                  No service charge shall be made for any registration of
transfer or exchange of Securities, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith.

                  Prior to due presentment of this Security for registration of
transfer, the Company, any Guarantor, the Trustee and any agent of the Company,
any Guarantor or the Trustee may treat the Person in whose name this Security is
registered as the owner hereof for all purposes, whether or not this Security is
overdue, and neither the Company, any Guarantor, the Trustee nor any such agent
shall be affected by notice to the contrary.

                  THIS SECURITY SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE
WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO CONFLICTS OF LAWS
PRINCIPLES THEREOF.

                  All terms used in this Security which are defined in the
Indenture and not otherwise defined herein shall have the meanings assigned to
them in the Indenture.

                  (b)      The form of the reverse of the Series B Securities
shall be substantially as follows:

Securities will be consolidated and form a single series with the Initial
Securities and have the same terms as to status, redemption or otherwise as the
Initial Securities.

                  The Securities are subject to redemption at any time on or
after January 15, 2008, at the option of the Company, in whole or in part, on
not less than 30 nor more than 60 days' prior notice, in amounts of $1,000 or an
integral multiple thereof, at the following redemption prices (expressed as
percentages of the principal amount), if redeemed during the 12-month period
beginning January 15th of the years indicated below:

<TABLE>

                    Redemption

2010                 101.479%
</TABLE>

and thereafter at 100% of the principal amount, in each case, together with
accrued and unpaid interest, if any, to the Redemption Date (subject to the
rights of Holders of record on relevant record dates to receive interest due on
an Interest Payment Date).

                  In addition, at any time prior to January 15, 2006, the
Company may, at its option, use the net proceeds of one or more Public Equity
Offerings to redeem up to an aggregate of 35% of the aggregate principal amount
of Securities issued under the Indenture (including the principal amount of any
Additional Securities issued under the Indenture) at a redemption price equal to
108.875% of the aggregate principal amount thereof, plus accrued and unpaid
interest thereon, if any, to the Redemption Date; provided that at least 65% of
the aggregate principal amount of Securities (including the principal amount of
any Additional Securities issued under the Indenture) remains outstanding
immediately after the occurrence of such redemption. In order to effect the
foregoing redemption, the Company must mail a notice of redemption no later

                                       - -
<PAGE>
than 30 days after the closing of the related Public Equity Offering and must
consummate such redemption within 60 days of the closing of the Public Equity
Offering.

                  If less than all of the Securities are to be redeemed, the
Trustee shall select the Securities or portions thereof to be redeemed in
compliance with the requirements of the principal national securities exchange,
if any, on which the Securities are listed or, if the Securities are not so
listed, pro rata, by lot or by any other method the Trustee shall deem fair and
reasonable.

                  Upon the occurrence of a Change of Control, each Holder may
require the Company to purchase such Holder's Securities in whole or in part in
integral multiples of $l,000, at a purchase price in cash in an amount equal to
101% of the principal amount thereof, plus accrued and unpaid interest, if any,
to the date of purchase, pursuant to a Change of Control Offer in accordance
with the procedures set forth in the Indenture.

                  Under certain circumstances described in the Indenture, the
Company will be required to apply the proceeds of Asset Sales to the repayment
of the Securities and Pari Passu Indebtedness.

                  In the case of any redemption or repurchase of Securities in
accordance with the Indenture, interest installments whose Stated Maturity is on
or prior to the Redemption Date will be payable to the Holders of such
Securities of record as of the close of business on the relevant Regular Record
Date or Special Record Date referred to on the face hereof. Securities (or
portions thereof) for whose redemption and payment provision is made in
accordance with the Indenture shall cease to bear interest from and after the
Redemption Date.

                  In the event of redemption or repurchase of this Security in
accordance with the Indenture in part only, a new Security or Securities for the
unredeemed portion hereof shall be issued in the name of the Holder hereof upon
the cancellation hereof.

                  If an Event of Default shall occur and be continuing, the
principal amount of all the Securities may be declared due and payable in the
manner and with the effect provided in the Indenture.

                  The Indenture contains provisions for defeasance at any time
of (a) the entire Indebtedness on the Securities and (b) certain restrictive
covenants and related Defaults and Events of Default, in each case upon
compliance with certain conditions set forth therein.

                  The Indenture permits, with certain exceptions (including
certain amendments permitted without the consent of any Holders and certain
amendments which require the consent of all the Holders) as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Company and the Guarantors and the rights of the Holders under the Indenture and
the Securities and the Guarantees at any time by the Company and the Trustee
with the consent of the Holders of at least a majority in aggregate principal
amount of the Securities at the time Outstanding. The Indenture also contains
provisions permitting, with certain exceptions (including certain waivers which
require the consent of all of the Holders) as therein provided, the Holders of
at least a majority in aggregate principal amount of the Securities at the time
Outstanding, on behalf of the Holders of all the Securities, to waive

                                       - -
<PAGE>
compliance by the Company and the Guarantors with certain provisions of the
Indenture and the Securities and the Guarantees and certain past Defaults under
the Indenture and the Securities and the Guarantees and their consequences. Any
such consent or waiver by or on behalf of the Holder of this Security shall be
conclusive and binding upon such Holder and upon all future Holders of this
Security and of any Security issued upon the registration of transfer hereof or
in exchange herefor or in lieu hereof whether or not notation of such consent or
waiver is made upon this Security.

                  The Securities are, to the extent and manner provided in
Article Thirteen of the Indenture, subordinated and subject in right of payment
to the prior payment in full in cash (or in any other form as acceptable to the
holders of Senior Indebtedness) of all Senior Indebtedness.

                  No reference herein to the Indenture and no provision of this
Security or of the Indenture shall alter or impair the obligation of the
Company, any Guarantor or any other obligor on the Securities (in the event such
Guarantor or such other obligor is obligated to make payments in respect of the
Securities), which is absolute and unconditional, to pay the principal of, and
premium, if any, and interest on, this Security at the times, place, and rate,
and in the coin or currency, herein prescribed.

                  As provided in the Indenture and subject to certain
limitations therein set forth, the transfer of this Security is registrable in
the Security Register, upon surrender of this Security for registration of
transfer at the Corporate Trust Office or the office or agency of the Company in
the Borough of Manhattan, The City of New York, duly endorsed by, or accompanied
by a written instrument of transfer in form satisfactory to the Company and the
Security Registrar duly executed by, the Holder hereof or its attorney duly
authorized in writing, and thereupon one or more new Securities, of authorized
denominations and for the same aggregate principal amount, will be issued to the
designated transferee or transferees.

                  Certificated securities shall be transferred to all beneficial
holders in exchange for their beneficial interests in the Series B Securities if
(i) such Depositary (A) has notified the Company that it is unwilling or unable
to continue as Depositary for such Global Security or (B) has ceased to be a
clearing agency registered as such under the Exchange Act, and in either case
the Company fails to appoint a successor Depositary within 90 days, (ii) the
Company, at its option, notifies the Trustee in writing that it elects to cause
the issuance of the Securities in certificated form or (iii) there shall have
occurred and be continuing an Event of Default with respect to such Global
Security. Upon any such issuance, the Trustee is required to register such
certificated Series B Securities in the name of, and cause the same to be
delivered to, such Person or Persons (or the nominee of any thereof).

                  Series B Securities in certificated form are issuable only in
registered form without coupons in denominations of $1,000 and any integral
multiple thereof. As provided in the Indenture and subject to certain
limitations therein set forth, the Series B Securities are exchangeable for a
like aggregate principal amount of Securities of a differing authorized
denomination, as requested by the Holder surrendering the same.

                  No service charge shall be made for any registration of
transfer or exchange of Securities, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith.

                  Prior to due presentment of this Security for registration of
transfer, the Company, any Guarantor, the Trustee and any agent of the Company,
any Guarantor or the Trustee may treat the Person in whose name this Security is
registered as the owner hereof for all purposes, whether or not this Security is
overdue, and neither the Company, any Guarantor, the Trustee nor any such agent
shall be affected by notice to the contrary.

                  THIS SECURITY SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE
WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO CONFLICTS OF LAWS
PRINCIPLES THEREOF.

                  All terms used in this Security which are defined in the
Indenture and not otherwise defined herein shall have the meanings assigned to
them in the Indenture.

         Section 204.      Form of Guarantee.

                  The form of Guarantee shall be set forth on the Securities
(including both Series A Securities and Series B Securities) substantially as
follows:

                                   GUARANTEE

         For value received, each of the undersigned hereby absolutely, fully
and unconditionally and irrevocably guarantees, jointly and severally with each
other Guarantor, to the holder of this Security the payment of principal of,
premium, if any, and interest on this Security upon which these Guarantees are
endorsed in the amounts and at the time when due and payable whether by
declaration thereof, or otherwise, and interest on the overdue principal and
interest, if any, of this Security, if lawful, and the payment or performance of
all other obligations of the Company under the Indenture or the Securities, to
the holder of this Security and the Trustee, all in accordance with and subject
to the terms and limitations of this Security and Article Fourteen of the
Indenture. This Guarantee will not become effective until the Trustee duly
executes the certificate of authentication on this Security. These Guarantees
shall be governed by and construed in accordance with the laws of the State of
New York, without regard to conflict of law principles thereof. The Indebtedness
evidenced by these Guarantees is, to the extent and in the manner provided in
the Indenture, subordinate and subject in right of payment to the prior payment
in full in cash (or in any other form as acceptable to the holders of Senior
Guarantor Indebtedness) of all Senior Guarantor Indebtedness, whether
outstanding on the date of the Indenture or thereafter, and the Guarantees are
issued subject to such provisions.

                                 ARTICLE THREE

                                 THE SECURITIES

         Section 301.      Title and Terms.

                  The initial aggregate principal amount of Securities which may
be authenticated and delivered under this Indenture is $300,000,000 in principal
amount of Securities, except for Securities authenticated and delivered upon
registration of transfer of, or in exchange for, or in lieu of, other Securities
pursuant to Section 303, 304, 305, 306, 307, 308, 906, 1012, 1015 or 1108.
Notwithstanding the foregoing, the Company may, from time to time, without
notice to or the consent of the Holders of Securities, create and issue
Additional Securities under this Indenture ranking equally with the Initial
Securities in all respects (or in all respects other than the payment of
interest accruing prior to the issue date of such Additional Securities or
except for the first payment of interest following the issue date of such
Additional Securities), subject to the limitations described in Section 1008
hereof. Such Additional Securities will be consolidated and form a single series
with the Initial Securities and have the same terms as to status, redemption or
otherwise as the Initial Securities.

                  The Securities shall be known and designated as the "8 7/8%
Senior Subordinated Notes due 2013" of the Company. The Stated Maturity of the
Securities shall be January 15, 2013, and the Securities shall each bear
interest at the rate of 8 7/8% per annum, as such interest rate may be adjusted
as set forth in the Securities, from December 26, 2002, or from the most recent
Interest Payment Date to which interest has been paid, payable semiannually on
January 15th and July 15th in each year, commencing July 15, 2003, until the
principal thereof is paid or duly provided for. Interest on any overdue
principal, interest (to the extent lawful) or premium, if any, shall be payable
on demand.

                                       - -
<PAGE>
                  The principal of, premium, if any, and interest on, the
Securities shall be payable and the Securities shall be exchangeable and
transferable at the Corporate Trust Office; provided, however, that payment of
interest may be made at the option of the Company by check mailed to addresses
of the Persons entitled thereto as shown on the Security Register.

                  For all purposes hereunder, the Series A Securities and the
Series B Securities will be treated as one class and are together referred to as
the "Securities." The Series A Securities rank pari passu in right of payment
with the Series B Securities.

                  The Securities shall be subject to repurchase by the Company
pursuant to an Offer as provided in Section 1012.

                  Holders shall have the right to require the Company to
purchase their Securities, in whole or in part, in the event of a Change of
Control pursuant to Section 1015.

                  The Securities shall be redeemable as provided in Article
Eleven and in the Securities.

                  The Indebtedness evidenced by the Securities shall rank junior
to and be subordinated in right of payment to the prior payment in full in cash
(or in any other form as acceptable to the holders of Senior Indebtedness) of
all other Senior Indebtedness.

                  At the election of the Company, the entire Indebtedness on the
Securities or certain of the Company's obligations and covenants and certain
Events of Default thereunder may be defeased as provided in Article Four.

         Section 302.      Denominations.

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

         Section 303.      Execution, Authentication, Delivery and Dating.

                  The Securities shall be executed on behalf of the Company by
one of its Chairman of the Board, its President, its Chief Executive Officer,
its Chief Financial Officer or one of its Vice Presidents whose signatures shall
be attested by its Clerk, its Secretary or one of its Assistant Secretaries or
Assistant Clerks. The signatures of any of these officers on the Securities may
be manual or facsimile.

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

                  At any time and from time to time after the execution and
delivery of this Indenture, the Company may deliver Securities executed by the
Company to the Trustee (with Guarantees endorsed thereon) for authentication,
together with a Company Order for the authentication and delivery of such
Securities; and the Trustee in accordance with such Company

                                       - -
<PAGE>
Order shall authenticate and deliver such Securities as provided in this
Indenture and not otherwise.

                  Each Security shall be dated the date of its authentication.

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

                  In case the Company or any Guarantor, pursuant to Article
Eight, shall, in a single transaction or through a series of related
transactions, be consolidated or merged with or into any other Person or shall
sell, assign, convey, transfer, lease or otherwise dispose of all or
substantially all of its properties and assets to any Person, and the successor
Person resulting from such consolidation or surviving such merger, or into which
the Company or such Guarantor shall have been merged, or the successor Person
which shall have participated in the sale, assignment, conveyance, transfer,
lease or other disposition as aforesaid, shall have executed an indenture
supplemental hereto with the Trustee pursuant to Article Eight, any of the
Securities authenticated or delivered prior to such consolidation, merger, sale,
assignment, conveyance, transfer, lease or other disposition may, from time to
time, at the request of the successor Person, be exchanged for other Securities
executed in the name of the successor Person with such changes in phraseology
and form as may be appropriate, but otherwise in substance of like tenor as the
Securities surrendered for such exchange and of like principal amount; and the
Trustee, upon the request of the successor Person, shall authenticate and
deliver Securities as specified in such request for the purpose of such
exchange. If Securities shall at any time be authenticated and delivered in any
new name of a successor Person pursuant to this Section 303 in exchange or
substitution for or upon registration of transfer of any Securities, such
successor Person, at the option of the Holders but without expense to them,
shall provide for the exchange of all Securities at the time Outstanding for
Securities authenticated and delivered in such new name.

                  The Trustee may appoint an authenticating agent reasonably
acceptable to the Company to authenticate Securities on behalf of the Trustee.
Unless limited by the terms of such appointment, an authenticating agent may
authenticate Securities whenever the Trustee may do so. Each reference in this
Indenture to authentication by the Trustee includes authentication by such
agent. An authenticating agent has the same rights as any Security Registrar or
Paying Agent to deal with the Company and the Guarantors.

         Section 304.      Temporary Securities.

                  Pending the preparation of definitive Securities, the Company
may execute, and upon Company Order the Trustee shall authenticate and deliver,
temporary Securities which are printed, lithographed, typewritten or otherwise
produced, in any authorized denomination, substantially of the tenor of the
definitive Securities in lieu of which they are issued and with such appropriate
insertions, omissions, substitutions and other variations as the officers

                                       - -
<PAGE>
executing such Securities may determine, as conclusively evidenced by their
execution of such Securities.

                  If temporary Securities are issued, the Company will cause
definitive Securities to be prepared without unreasonable delay. After the
preparation of definitive Securities, the temporary Securities shall be
exchangeable for definitive Securities upon surrender of the temporary
Securities at the office or agency of the Company designated for such purpose
pursuant to Section 1002, without charge to the Holder. Upon surrender for
cancellation of any one or more temporary Securities, the Company shall execute
and the Trustee shall authenticate and deliver in exchange therefor a like
principal amount of definitive Securities of authorized denominations. Until so
exchanged the temporary Securities shall in all respects be entitled to the same
benefits under this Indenture as definitive Securities.

         Section 305.      Registration, Registration of Transfer and Exchange.

                  The Company shall cause the Trustee to keep, so long as it is
the Security Registrar, at the Corporate Trust Office of the Trustee, or such
other office as the Trustee may designate, a register (the register maintained
in such office or in any other office or agency designated pursuant to Section
1002 being herein sometimes referred to as the "Security Register") in which,
subject to such reasonable regulations as the Security Registrar may prescribe,
the Company shall provide for the registration of Securities and of transfers of
Securities. The Trustee shall initially be the "Security Registrar" for the
purpose of registering Securities and transfers of Securities as herein
provided. The Company may change the Security Registrar or appoint one or more
co-Security Registrars without notice.

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

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

                  At the option of the Holder, Securities of any authorized
denomination or denominations may be exchanged for other Securities of a like
aggregate principal amount, upon surrender of the Securities to be exchanged at
such office or agency. Whenever any Securities are so surrendered for exchange,
the Company shall execute, and the Trustee shall authenticate and deliver,
Securities of the same series which the Holder making the exchange is entitled
to receive; provided that no exchange of Series A Securities for Series B
Securities shall occur until an Exchange Offer Registration Statement shall have
been declared effective by the Commission and the Exchange Offer shall have
expired; and provided, further, however that the Series A Securities exchanged
for the Series B Securities shall be canceled.

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

                  Every Security presented or surrendered for registration of
transfer, or for exchange, repurchase or redemption, shall (if so required by
the Company or the Trustee) be duly endorsed, or be accompanied by a written
instrument of transfer in form satisfactory to the Company and the Security
Registrar, duly executed by the Holder thereof or his attorney duly authorized
in writing.

                  No service charge shall be made to a Holder for any
registration of transfer, exchange or redemption of Securities, except for any
tax or other governmental charge that may be imposed in connection therewith,
other than exchanges pursuant to Sections 303, 304, 305, 308, 906, 1012, 1015 or
1108 not involving any transfer.

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

                  Every Security shall be subject to the restrictions on
transfer provided in the legend required to be set forth on the face of each
Security pursuant to Section 202, and the restrictions set forth in this Section
305, and the Holder of each Security, by such Holder's acceptance thereof (or
interest therein), agrees to be bound by such restrictions on transfer.

                  Except as provided in Section 306(b) hereof, any Security
authenticated and delivered upon registration of transfer of, or in exchange
for, or in lieu of, any Global Security, whether pursuant to this Section 305,
Section 304, 308, 906 or 1108 or otherwise, shall also be a Global Security and
bear the legend specified in Section 202.

         Section 306.      Book Entry Provisions for Global Securities.

                  (a) Each Global Security initially shall (i) be registered in
the name of the Depositary for such Global Security or the nominee of such
Depositary, (ii) be deposited with, or on behalf of, the Depositary or with the
Trustee as custodian for such Depositary and (iii) bear legends as set forth in
Section 202.

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

                                       - -

the Depositary and its Agent Members, the operation of customary practices
governing the exercise of the rights of a holder of any Security.

                  (b)      Notwithstanding any other provision in this
Indenture, no Global Security may be exchanged in whole or in part for
Securities registered, and no transfer of a Global Security in whole or in part
may be registered, in the name of any Person other than the Depositary for such
Global Security or a nominee thereof unless (i) such Depositary (A) has notified
the Company that it is unwilling or unable to continue as Depositary for such
Global Security or (B) has ceased to be a clearing agency registered as such
under the Exchange Act, and in either case the Company fails to appoint a
successor Depositary within 90 days, (ii) the Company, at its option, executes
and delivers to the Trustee a Company Order stating that it elects to cause the
issuance of the Securities in certificated form and that all Global Securities
shall be exchanged in whole for Securities that are not Global Securities (in
which case such exchange shall be effected by the Trustee) or (iii) there shall
have occurred and be continuing an Event of Default with respect to such Global
Security.

                  (c)      If any Global Security is to be exchanged for other
Securities or canceled in whole, it shall be surrendered by or on behalf of the
Depositary or its nominee to the Trustee, as Security Registrar, for exchange or
cancellation as provided in this Article Three. If any Global Security is to be
exchanged for other Securities or canceled in part, or if another Security is to
be exchanged in whole or in part for a beneficial interest in any Global
Security, then either (i) such Global Security shall be so surrendered for
exchange or cancellation as provided in this Article Three or (ii) the principal
amount thereof shall be reduced or increased by an amount equal to the portion
thereof to be so exchanged or canceled, or equal to the principal amount of such
other Security to be so exchanged for a beneficial interest therein, as the case
may be, by means of an appropriate adjustment made on the records of the
Trustee, as Security Registrar, whereupon the Trustee, in accordance with the
Applicable Procedures, shall instruct the Depositary or its authorized
representative to make a corresponding adjustment to its records. Upon any such
surrender or adjustment of a Global Security, the Trustee shall, subject to this
Section 306(c) and as otherwise provided in this Article Three, authenticate and
deliver any Securities issuable in exchange for such Global Security (or any
portion thereof) to or upon the order of, and registered in such names as may be
directed by, the Depositary or its authorized representative. Upon the request
of the Trustee in connection with the occurrence of any of the events specified
in the preceding paragraph, the Company shall promptly make available to the
Trustee a reasonable supply of Securities that are not in the form of Global
Securities. The Trustee shall be entitled to rely upon any order, direction or
request of the Depositary or its authorized representative which is given or
made pursuant to this Article Three if such order, direction or request is given
or made in accordance with the Applicable Procedures.

                  (d)      The Depositary or its nominee, as registered owner of
a Global Security, shall be the Holder of such Global Security for all purposes
under this Indenture and the Securities, and owners of beneficial interests in a
Global Security shall hold such interests pursuant to the Applicable Procedures.
Accordingly, any such owner's beneficial interest in a Global Security will be
shown only on, and the transfer of such interest shall be effected only through,
records maintained by the Depositary or its nominee or its Agent Members.

         Section 307.      Special Transfer and Exchange Provisions.

                  (a)      Certain Transfers and Exchanges. Transfers and
exchanges of Securities and beneficial interests in a Global Security of the
kinds specified in this Section 307 shall be made only in accordance with this
Section 307 and subject in each case to the Applicable Procedures.

                           (i)      Rule 144A Global Security to Regulation S
                  Global Security. If the owner of a beneficial interest in the
                  Rule 144A Global Security wishes at any time to transfer such
                  interest to a Person who wishes to acquire the same in the
                  form of a beneficial interest in the Regulation S Global
                  Security, such transfer may be effected only in accordance
                  with the provisions of this paragraph and paragraph (iv) below
                  and subject to the Applicable Procedures. Upon receipt by the
                  Trustee, as Security Registrar, of (a) an order given by the
                  Depositary or its authorized representative directing that a
                  beneficial interest in the Regulation S Global Security in a
                  specified principal amount be credited to a specified Agent
                  Member's account and that a beneficial interest in the Rule
                  144A Global Security in an equal principal amount be debited
                  from another specified Agent Member's account and (b) a
                  Regulation S Certificate in the form of Exhibit A hereto,
                  satisfactory to the Trustee and duly executed by the owner of
                  such beneficial interest in the Rule 144A Global Security or
                  his attorney duly authorized in writing, then the Trustee, as
                  Security Registrar but subject to paragraph (iv) below, shall
                  reduce the principal amount of the Rule 144A Global Security
                  and increase the principal amount of the Regulation S Global
                  Security by such specified principal amount as provided in
                  Section 306(c).

                           (ii)     Regulation S Global Security to Rule 144A
                  Global Security. If the owner of a beneficial interest in the
                  Regulation S Global Security wishes at any time to transfer
                  such interest to a Person who wishes to acquire the same in
                  the form of a beneficial interest in the Rule 144A Global
                  Security, such transfer may be effected only in accordance
                  with this paragraph (ii) and subject to the Applicable
                  Procedures. Upon receipt by the Trustee, as Security
                  Registrar, of (a) an order given by the Depositary or its
                  authorized representative directing that a beneficial interest
                  in the Rule 144A Global Security in a specified principal
                  amount be credited to a specified Agent Member's account and
                  that a beneficial interest in the Regulation S Global Security
                  in an equal principal amount be debited from another specified
                  Agent Member's account and (b) if such transfer is to occur
                  during the Restricted Period, a Restricted Securities
                  Certificate in the form of Exhibit B hereto, satisfactory to
                  the Trustee and duly executed by the owner of such beneficial
                  interest in the Regulation S Global Security or his attorney
                  duly authorized in writing, then the Trustee, as Security
                  Registrar, shall reduce the principal amount of the Regulation
                  S Global Security and increase the principal amount of the
                  Rule 144A Global Security by such specified principal amount
                  as provided in Section 306(c).

                           (iii)    Exchanges between Global Security and
                  Non-Global Security. Subject to the provisions of Section
                  306(c) herein, a beneficial interest in a Global

                                       - -
<PAGE>
                  Security may be exchanged for a Security that is not a Global
                  Security as provided in Section 307(b), provided that, if such
                  interest is a beneficial interest in the Rule 144A Global
                  Security, or if such interest is a beneficial interest in the
                  Regulation S Global Security and such exchange is to occur
                  during the Restricted Period, then such interest shall bear
                  the Private Placement Legend (subject in each case to Section
                  307(b)).

                           (iv)     Regulation S Global Security to be Held
                  Through Euroclear or Clearstream during Restricted Period. The
                  Company shall use its best efforts to cause the Depositary to
                  ensure that, until the expiration of the Restricted Period,
                  beneficial interests in the Regulation S Global Security may
                  be held only in or through accounts maintained at the
                  Depositary by Euroclear or Clearstream (or by Agent Members
                  acting for the account thereof), and no person shall be
                  entitled to effect any transfer or exchange that would result
                  in any such interest being held otherwise than in or through
                  such an account; provided that this paragraph (iv) shall not
                  prohibit any transfer or exchange of such an interest in
                  accordance with paragraph (ii) above.

                  (b)      Private Placement Legends. Rule 144A Securities and
their Successor Securities and Regulation S Securities and their Successor
Securities shall bear a Private Placement Legend, subject to the following:

                           (i)      subject to the following clauses of this
                  Section 307(b), a Security or any portion thereof which is
                  exchanged, upon transfer or otherwise, for a Global Security
                  or any portion thereof shall bear the Private Placement Legend
                  borne by such Global Security while represented thereby;

                           (ii)     subject to the following clauses of this
                  Section 307(b) and the provisions of Section 306(c) herein, a
                  new Security which is not a Global Security and is issued in
                  exchange for another Security (including a Global Security) or
                  any portion thereof, upon transfer or otherwise, shall bear
                  the Private Placement Legend borne by such other Security;

                           (iii)    all Securities sold or otherwise disposed of
                  pursuant to an effective registration statement under the
                  Securities Act, together with their respective Successor
                  Securities, shall not bear a Private Placement Legend;

                           (iv)     at any time after the Securities may be
                  freely transferred without registration under the Securities
                  Act or without being subject to transfer restrictions pursuant
                  to the Securities Act, a new Security which does not bear a
                  Private Placement Legend may be issued in exchange for or in
                  lieu of a Security (other than a Global Security) or any
                  portion thereof which bears such a legend if the Trustee has
                  received an Unrestricted Securities Certificate substantially
                  in the form of Exhibit C hereto, satisfactory to the Trustee
                  and duly executed by the Holder of such legended Security or
                  his attorney duly authorized in writing, and after such date
                  and receipt of such certificate, the Trustee shall
                  authenticate and

                                       - -
<PAGE>
                  deliver such new Security in exchange for or in lieu of such
                  other Security as provided in this Article Three;

                           (v)      a new Security which does not bear a Private
                  Placement Legend may be issued in exchange for or in lieu of a
                  Security (other than a Global Security) or any portion thereof
                  which bears such a legend if, in the Company's judgment,
                  placing such a legend upon such new Security is not necessary
                  to ensure compliance with the registration requirements of the
                  Securities Act, and the Trustee, at the direction of the
                  Company, shall authenticate and deliver such a new Security as
                  provided in this Article Three; and

                           (vi)     notwithstanding the foregoing provisions of
                  this Section 307(b), a Successor Security of a Security that
                  does not bear a particular form of Private Placement Legend
                  shall not bear such form of legend unless the Company has
                  reasonable cause to believe that such Successor Security is a
                  "restricted security" within the meaning of Rule 144, in which
                  case the Trustee, at the direction of the Company, shall
                  authenticate and deliver a new Security bearing a Private
                  Placement Legend in exchange for such Successor Security as
                  provided in this Article Three.

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

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

                  (c)      No Obligation of the Trustee.

                  The Trustee shall have no responsibility or obligation to any
beneficial owner of a Global Security, a member of, or a participant in the
Depository or other Person with respect to the accuracy of the books or records,
or the acts or omissions, of the Depository or its nominee or of any participant
or member thereof, with respect to any ownership interest in the Securities or
with respect to the delivery to any participant, member, beneficial owner or
other Person (other than the Depository) of any notice (including any notice of
redemption) or the payment of any amount, under or with respect to such
Securities. All notices and communications to be given to the Holders and all
payments to be made to Holders under the Securities shall be given or made only
to or upon the order of the registered Holders (which shall be the Depository or
its nominee in the case of a Global Security). The rights of beneficial owners
in any Global Security shall be exercised only through the Depository subject to
the Applicable Procedures of the Depository. The Trustee may rely and shall be
fully protected in relying upon information furnished by the Depository with
respect to its members, participants and any beneficial owners.

<PAGE>
                  The Trustee shall have no obligation or duty to monitor,
determine or inquire as to compliance with any restrictions on transfer imposed
under this Indenture or under applicable law with respect to any transfer of any
interest in any Security (including any transfers between or among Depository
participants, members or beneficial owners in any Global Security) other than to
require delivery of such certificates and other documentation or evidence as are
expressly required by, and to do so if and when expressly required by, the terms
of this Indenture, and to examine the same to determine substantial compliance
as to form with the express requirements hereof.

         Section 308.      Mutilated, Destroyed, Lost and Stolen Securities.

                  If (a) any mutilated Security is surrendered to the Trustee,
or (b) the Company and the Trustee receive evidence to their satisfaction of the
destruction, loss or theft of any Security, and there is delivered to the
Company, any Guarantor and the Trustee, such security or indemnity, in each
case, as may be required by them to save each of them harmless, then, in the
absence of notice to the Company, any Guarantor or the Trustee that such
Security has been acquired by a bona fide purchaser, the Company shall execute
and upon a Company Request the Trustee shall authenticate and deliver, in
exchange for any such mutilated Security or in lieu of any such destroyed, lost
or stolen Security, a replacement Security of like tenor and principal amount,
bearing a number not contemporaneously outstanding and each Guarantor shall
execute a replacement Guarantee.

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

                  Upon the issuance of any replacement Securities under this
Section, the Company may require the payment of a sum sufficient to pay all
documentary, stamp or similar issue or transfer taxes or other governmental
charges that may be imposed in relation thereto and any other expenses
(including the fees and expenses of the Trustee) connected therewith.

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

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

         Section 309.      Payment of Interest; Interest Rights Preserved.

                  Interest on any Security which is payable, and is punctually
paid or duly provided for, on the Stated Maturity of such interest shall be paid
to the Person in whose name the Security (or any Predecessor Securities) is
registered at the close of business on the Regular Record Date for such interest
payment.

                  Any interest on any Security which is payable, but is not
punctually paid or duly provided for, on the Stated Maturity of such interest,
and interest on such defaulted interest at the then applicable interest rate
borne by the Securities, to the extent lawful (such defaulted interest and
interest thereon herein collectively called "Defaulted Interest"), shall
forthwith cease to be payable to the Holder on the Regular Record Date; and such
Defaulted Interest may be paid by the Company, at its election in each case, as
provided in Subsection (a) or (b) below:

                  (a)      The Company may elect to make payment of any
                  Defaulted Interest to the Persons in whose names the
                  Securities (or any relevant Predecessor Securities) are
                  registered at the close of business on a Special Record Date
                  for the payment of such Defaulted Interest, which shall be
                  fixed in the following manner. The Company shall notify the
                  Trustee in writing of the amount of Defaulted Interest
                  proposed to be paid on each Security and the date (not less
                  than 30 days after such notice) of the proposed payment (the
                  "Special Payment Date"), and at the same time the Company
                  shall deposit with the Trustee an amount of money equal to the
                  aggregate amount proposed to be paid in respect of such
                  Defaulted Interest or shall make arrangements satisfactory to
                  the Trustee for such deposit prior to the Special Payment
                  Date, such money when deposited to be held in trust for the
                  benefit of the Persons entitled to such Defaulted Interest as
                  in this Subsection provided. Thereupon the Trustee shall fix a
                  Special Record Date for the payment of such Defaulted Interest
                  which shall be not more than 15 days and not less than 10 days
                  prior to the date of the Special Payment Date and not less
                  than 10 days after the receipt by the Trustee of the notice of
                  the proposed payment. The Trustee shall promptly notify the
                  Company in writing of such Special Record Date. In the name
                  and at the expense of the Company, the Trustee shall cause
                  notice of the proposed payment of such Defaulted Interest and
                  the Special Record Date therefor to be mailed, first-class
                  postage prepaid, to each Holder at its address as it appears
                  in the Security Register, not less than 10 days prior to such
                  Special Record Date. Notice of the proposed payment of such
                  Defaulted Interest and the Special Record Date and Special
                  Payment Date therefor having been so mailed, such Defaulted
                  Interest shall be paid to the Persons in whose names the
                  Securities are registered on such Special Record Date and
                  shall no longer be payable pursuant to the following
                  Subsection (b).

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

         Section 310.      CUSIP Numbers.

                  The Company in issuing the Securities may use "CUSIP" numbers
(if then generally in use), and the Company, or the Trustee on behalf of the
Company, shall use CUSIP numbers in notices of redemption or exchange as a
convenience to Holders; provided, however, that any such notice shall state that
no representation is made as to the correctness of such numbers either as
printed on the Securities or as contained in any notice of redemption or
exchange and that reliance may be placed only on the other identification
numbers printed on the Securities; and provided further, however, that failure
to use CUSIP numbers in any notice of redemption or exchange shall not affect
the validity or sufficiency of such notice.

         Section 311.      Persons Deemed Owners.

                  Prior to and at the time of due presentment of a Security for
registration of transfer, the Company, any Guarantor, the Trustee and any agent
of the Company, any Guarantor or the Trustee may treat the Person in whose name
any Security is registered as the owner of such Security for the purpose of
receiving payment of principal of, premium, if any, and (subject to Section 309)
interest on, such Security and for all other purposes whatsoever, whether or not
such Security is overdue, and neither the Company, any Guarantor, the Trustee
nor any agent of the Company, any Guarantor or the Trustee shall be affected by
notice to the contrary.

         Section 312.      Cancellation.

                  All Securities surrendered for payment, purchase, redemption,
registration of transfer or exchange shall be delivered to the Trustee and, if
not already canceled, shall be promptly canceled by it. The Company and any
Guarantor may at any time deliver to the Trustee for cancellation any Securities
previously authenticated and delivered hereunder which the Company or such
Guarantor may have acquired in any manner whatsoever, and all Securities so
delivered shall be promptly canceled by the Trustee. No Securities shall be
authenticated in lieu of or in exchange for any Securities canceled as provided
in this Section 312, except as expressly permitted by this Indenture. All
canceled Securities held by the Trustee shall be destroyed and certification of
their destruction delivered to the Company, unless by a Company Order received
by the Trustee prior to such destruction, the Company shall direct that the
canceled Securities be returned to it. The Trustee shall provide the Company a
list of all Securities that have been canceled from time to time as requested by
the Company.

         Section 313.      Computation of Interest.

                  Interest on the Securities shall be computed on the basis of a

                       DEFEASANCE AND COVENANT DEFEASANCE

         Section 401.      Company's Option to Effect Defeasance or Covenant
                           Defeasance.

                  The Company may, at its option by Board Resolution, at any
time, with respect to the Securities, elect to have either Section 402 or
Section 403 be applied to all of the Outstanding Securities (the "Defeased
Securities"), upon compliance with the conditions set forth below in this
Article Four.

         Section 402.      Defeasance and Discharge.

                  Upon the Company's exercise under Section 401 of the option
applicable to this Section 402, the Company, each Guarantor and any other
obligor upon the Securities, if any, shall be deemed to have been discharged
from its obligations with respect to the Defeased Securities on the date the
conditions set forth in Section 404 below are satisfied (hereinafter,
"defeasance"). For this purpose, such defeasance means that the Company, each
Guarantor and any other obligor under this Indenture shall be deemed to have
paid and discharged the entire Indebtedness represented by the Defeased
Securities, which shall thereafter be deemed to be "Outstanding" only for the
purposes of Section 405 and the other Sections of this Indenture referred to in
(a) and (b) below, and to have satisfied all its other obligations under such
Securities and this Indenture insofar as such Securities are concerned (and the
Trustee, at the expense of the Company and upon Company Request, shall execute
proper instruments acknowledging the same), except for the following which shall
survive until otherwise terminated or discharged hereunder: (a) the rights of
Holders of Defeased Securities to receive, solely from the trust fund described
in Section 404 and as more fully set forth in such Section, payments in respect
of the principal of, premium, if any, and interest on, such Securities, when
such payments are due, (b) the Company's obligations with respect to such
Defeased Securities under Sections 304, 305, 308, 1002 and 1003, (c) the rights,
powers, trusts, duties and immunities of the Trustee hereunder, including,
without limitation, the Trustee's rights under Section 607, and (d) this Article
Four. Subject to compliance with this Article Four, the Company may exercise its
option under this Section 402 notwithstanding the prior exercise of its option
under Section 403 with respect to the Securities.

         Section 403.      Covenant Defeasance.

                  Upon the Company's exercise under Section 401 of the option
applicable to this Section 403, the Company and each Guarantor shall be released
from its obligations under any covenant or provision contained or referred to in
Sections 1005 through 1020, inclusive, and the provisions of clauses (3) and (5)
of Section 801(a), with respect to the Defeased Securities, on and after the
date the conditions set forth in Section 404 below are satisfied (hereinafter,
"covenant defeasance"), and the Defeased Securities shall thereafter be deemed
to be not "Outstanding" for the purposes of any direction, waiver, consent or
declaration or Act of Holders (and the consequences of any thereof) in
connection with such covenants, but shall continue to be deemed "Outstanding"
for all other purposes hereunder. For this purpose, such covenant defeasance
means that, with respect to the Defeased Securities, the Company and each
Guarantor

                                       - -
<PAGE>
may omit to comply with and shall have no liability in respect of any term,
condition or limitation set forth in any such Section, whether directly or
indirectly, by reason of any reference elsewhere herein to any such Section or
by reason of any reference in any such Section to any other provision herein or
in any other document and such omission to comply shall not constitute a Default
or an Event of Default under Section 501(c), and Defaults or Events of Default
under Section 501(d), (e) and (f) shall cease to apply, but, except as specified
above, the remainder of this Indenture and such Defeased Securities shall be
unaffected thereby.

         Section 404.      Conditions to Defeasance or Covenant Defeasance.

                  The following shall be the conditions to application of either
Section 402 or Section 403 to the Defeased Securities:

                  (1)      The Company shall irrevocably have deposited or
caused to be deposited with the Trustee as trust funds in trust for the purpose
of making the following payments, specifically pledged as security for, and
dedicated solely to, the benefit of the Holders of such Securities, (a) cash in
United States dollars in an amount, (b) U.S. Government Obligations which
through the scheduled payment of principal and interest in respect thereof in
accordance with their terms and with no further reinvestment will provide, not
later than one day before the due date of payment, money in an amount, or (c) a
combination thereof, in such amounts as will be sufficient, in the opinion of a
nationally recognized firm of independent public accountants or a nationally
recognized investment banking firm expressed in a written certification thereof
delivered to the Trustee, to pay and discharge, and which shall be applied by
the Trustee to pay and discharge, the principal of, premium, if any, and
interest on, the Defeased Securities, on the Stated Maturity of such principal
or interest (or on any date after January 15, 2008 (such date being referred to
as the "Defeasance Redemption Date") if at or prior to electing to exercise
either its option applicable to Section 402 or its option applicable to Section
403, the Company has delivered to the Trustee an irrevocable notice to redeem
the Defeased Securities on the Defeasance Redemption Date). For this purpose,
"U.S. Government Obligations" means securities that are (i) direct obligations
of the United States of America for the timely payment of which its full faith
and credit is pledged or (ii) obligations of a Person controlled or supervised
by and acting as an agency or instrumentality of the United States of America
the timely payment of which is unconditionally guaranteed as a full faith and
credit obligation by the United States of America, which, in either case, are
not callable or redeemable at the option of the issuer thereof, and shall also
include a depository receipt issued by a bank (as defined in Section 3(a)(2) of
the Securities Act), as custodian with respect to any such U.S. Government
Obligation or a specific payment of principal of or interest on any such U.S.
Government Obligation held by such custodian for the account of the holder of
such depository receipt, provided that (except as required by law) such
custodian is not authorized to make any deduction from the amount payable to the
holder of such depository receipt from any amount received by the custodian in
respect of the U.S. Government Obligation or the specific payment of principal
of or interest on the U.S. Government Obligation evidenced by such depository
receipt;

                  (2)      In the case of an election under Section 402, the
Company shall have delivered to the Trustee an Opinion of Independent Counsel in
the United States stating that (A) the Company has received from, or there has
been published by, the Internal Revenue Service a ruling or (B) since the date
hereof, there has been a change in the applicable federal

                                       - -
<PAGE>
income tax law, in either case to the effect that, and based thereon such
Opinion of Independent Counsel in the United States shall confirm that, the
Holders of the Outstanding Securities will not recognize income, gain or loss
for federal income tax purposes as a result of such defeasance and will be
subject to federal income tax on the same amounts, in the same manner and at the
same times as would have been the case if such defeasance had not occurred;

                  (3)      In the case of an election under Section 403, the
Company shall have delivered to the Trustee an Opinion of Independent Counsel in
the United States to the effect that the Holders of the Outstanding Securities
will not recognize income, gain or loss for federal income tax purposes as a
result of such covenant defeasance and will be subject to federal income tax on
the same amounts, in the same manner and at the same times as would have been
the case if such covenant defeasance had not occurred;

                  (4)      No Default or Event of Default shall have occurred
and be continuing on the date of such deposit or insofar as Section 501(g) or
(h) is concerned, at any time during the period ending on the 91st day after the
date of deposit (it being understood that this condition shall not be deemed
satisfied until the expiration of such period);

                  (5)      Such defeasance or covenant defeasance shall not
cause the Trustee for the Securities to have a conflicting interest in violation
of and for purposes of the Trust Indenture Act with respect to any securities of
the Company or any Guarantor;

                  (6)      Such defeasance or covenant defeasance shall not
result in a breach or violation of, or constitute a Default under, this
Indenture or any other material agreement or instrument to which the Company,
any Guarantor or any Restricted Subsidiary is a party or by which it is bound;

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

                  (8)      The Company will have delivered to the Trustee an
Opinion of Independent Counsel in the United States to the effect that (assuming
no Holder of the Securities would be considered an insider of the Company or any
Guarantor under any applicable bankruptcy or insolvency law and assuming no
intervening bankruptcy or insolvency of the Company or any Guarantor between the
date of deposit and the 9lst day following the deposit) after the 91st day
following the deposit, the trust funds will not be subject to the effect of any
applicable bankruptcy, insolvency, reorganization or similar laws affecting
creditors' rights generally which relates to preferences;

                  (9)      The Company shall have delivered to the Trustee an
Officers' Certificate stating that the deposit was not made by the Company with
the intent of preferring the holders of the Securities or any Guarantee over the
other creditors of the Company or any Guarantor with the intent of defeating,
hindering, delaying or defrauding creditors of the Company, any Guarantor or
others;

<PAGE>
                  (10)     No event or condition shall exist that would prevent
the Company from making payments of the principal of, premium, if any, and
interest on the Securities on the date of such deposit or at any time ending on
the 91st day after the date of such deposit; and

                  (11)     The Company shall have delivered to the Trustee an
Officers' Certificate and an Opinion of Independent Counsel, each stating that
all conditions precedent provided for relating to either the defeasance under
Section 402 or the covenant defeasance under Section 403 (as the case may be)
have been complied with.

                  Opinions of Counsel or Opinions of Independent Counsel
required to be delivered under this Section shall be in form and substance
reasonably satisfactory to the Trustee and may have qualifications customary for
opinions of the type required and counsel delivering such opinions may rely on
certificates of the Company or government or other officials customary for
opinions of the type required, which certificates shall be limited as to matters
of fact, including that various financial covenants have been complied with.

         Section 405.      Deposited Money and U.S. Government Obligations
to Be Held in Trust; Other Miscellaneous Provisions.

                  Subject to the provisions of the last paragraph of Section
1003, all United States dollars and U.S. Government Obligations (including the
proceeds thereof) deposited with the Trustee pursuant to Section 404 in respect
of the Defeased Securities shall be held in trust and applied by the Trustee, in
accordance with the provisions of such Securities and this Indenture, to the
payment, either directly or through any Paying Agent (excluding the Company or
any of its Affiliates acting as Paying Agent), as the Trustee may determine, to
the Holders of such Securities of all sums due and to become due thereon in
respect of principal, premium, if any, and interest, but such money need not be
segregated from other funds except to the extent required by law.

                  The Company shall pay and indemnify the Trustee against any
tax, fee or other charge imposed on or assessed against the U.S. Government
Obligations deposited pursuant to Section 404 or the principal and interest
received in respect thereof other than any such tax, fee or other charge which
by law is imposed, assessed or for the account of the Holders of the Defeased
Securities.

                  Anything in this Article Four to the contrary notwithstanding,
the Trustee shall deliver or pay to the Company from time to time upon Company
Request any United States dollars or U.S. Government Obligations held by it as
provided in Section 404 which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee, are in excess of the amount thereof which would then
be required to be deposited to effect defeasance or covenant defeasance.

         Section 406.      Reinstatement.

                  If the Trustee or Paying Agent is unable to apply any United
States dollars or U.S. Government Obligations in accordance with Section 402 or
403, as the case may be, by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, then the Company's obligations under this Indenture and the

                                       - -
<PAGE>
Securities and any Guarantor's obligations under any Guarantee shall be revived
and reinstated, with present and prospective effect, as though no deposit had
occurred pursuant to Section 402 or 403, as the case may be, until such time as
the Trustee or Paying Agent is permitted to apply all such United States dollars
or U.S. Government Obligations in accordance with Section 402 or 403, as the
case may be; provided, however, that if the Company makes any payment to the
Trustee or Paying Agent of principal of, premium, if any, or interest on any
Security following the reinstatement of its obligations, the Trustee or Paying
Agent shall promptly pay any such amount to the Holders of the Securities and
the Company shall be subrogated to the rights of the Holders of such Securities
to receive such payment from the United States dollars and U.S. Government
Obligations held by the Trustee or Paying Agent.

         Section 502.      Acceleration of Maturity; Rescission and Annulment.

                  If an Event of Default (other than an Event of Default
specified in Sections 501(g) and (h) within) shall occur and be continuing with
respect to this Indenture, the Trustee or the holders of not less than 25% in
aggregate principal amount of the Securities then Outstanding may, and the
Trustee at the request of such holders shall, declare all unpaid principal of,
premium, if any, and accrued interest on all Securities to be due and payable
immediately, by a notice in writing to the Company (and to the Trustee if given
by the holders of the Securities) and upon any such declaration, such principal,
premium, if any, and interest shall become due and payable immediately. If an
Event of Default specified in clause (g) or (h) of Section 501 occurs and is
continuing, then all the Securities shall ipso facto become and be due and
payable immediately in an amount equal to the principal amount of the
Securities, together with accrued and unpaid interest, if any, to the date the
Securities become due and payable, without any declaration or other act on the
part of the Trustee or any holder. Thereupon, the Trustee may, at its
discretion, proceed to protect and enforce the rights of the holders of the
Securities by appropriate judicial proceedings.

                  After a declaration of acceleration with respect to the
Securities, but before a judgment or decree for payment of the money due has
been obtained by the Trustee as hereinafter in this Article provided, the
Holders of a majority in aggregate principal amount of the Securities
Outstanding, by written notice to the Company and the Trustee, may rescind and
annul such declaration 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 under this
Indenture and the reasonable compensation, expenses, disbursements and advances
of the Trustee, its agents and counsel, (ii)

                                       - -
<PAGE>
all overdue interest on all Outstanding Securities, (iii) the principal of and
premium, if any, on any Outstanding Securities which have become due otherwise
than by such declaration of acceleration and interest thereon at the rate borne
by the Securities, and (iv) to the extent that payment of such interest is
lawful, interest upon overdue interest at the rate borne by the Securities;

                  (b)      the rescission would not conflict with any judgment
or decree of a court of competent jurisdiction; and

                  (c)      all Events of Default, other than the non-payment of
principal of, premium, if any, and interest on the Securities which have become
due solely by such declaration of acceleration, have been cured or waived as
provided in Section 513.

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

         Section 503.      Suits for Enforcement by Trustee.

                  If an Event of Default specified in Section 501(a) or 501(b)
hereof occurs and is continuing, the Trustee, in its own name and as trustee of
an express trust, may institute a judicial proceeding for the collection of the
whole amount then due and payable on such Securities for principal and premium,
if any, and interest, with interest upon the overdue principal and premium, if
any, and, to the extent that payment of such interest shall be legally
enforceable, upon overdue installments of interest, at the rate borne by the
Securities, and, in addition thereto, such further amount as shall be sufficient
to cover the costs and expenses of collection, including the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and may prosecute such proceeding to judgment or final decree, and
may enforce the same against the Company or any Guarantor or any other obligor
upon the Securities and collect the moneys adjudged or decreed to be payable in
the manner provided by law out of the property of the Company, any Guarantor or
any other obligor upon the Securities, wherever situated.

                  If an Event of Default occurs and is continuing, the Trustee
may in its discretion proceed to protect and enforce its rights and the rights
of the Holders under this Indenture or any Guarantee by such appropriate private
or judicial proceedings as the Trustee shall deem most effectual to protect and
enforce such rights, including seeking recourse against any Guarantor pursuant
to the terms of any Guarantee, whether for the specific enforcement of any
covenant or agreement in this Indenture or in aid of the exercise of any power
granted herein or therein, or to enforce any other proper remedy, including,
without limitation, seeking recourse against any Guarantor pursuant to the terms
of a Guarantee, or to enforce any other proper remedy, subject however to
Section 512. No recovery of any such judgment upon any property of the Company
or any Guarantor shall affect or impair any rights, powers or remedies of the
Trustee or the Holders.

         Section 504.      Trustee May File Proofs of Claim.

                  In case of the pendency of any receivership, insolvency,

other judicial proceeding relative to the Company or any other obligor,
including any Guarantor, upon the Securities or the property of

                                       - -

the Company or of such other obligor or their creditors, the Trustee
(irrespective of whether the principal of the Securities shall then be due and
payable as therein expressed or by declaration or otherwise and irrespective of
whether the Trustee shall have made any demand on the Company for the payment of
overdue principal or interest) shall be entitled and empowered, by intervention
in such proceeding or otherwise,

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

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

                  (c)      to take such other action with respect to such
claims, including participating as a member of any official committee of
creditors, as it reasonably deems necessary or advisable;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
similar official in any such judicial proceeding is hereby authorized by each
Holder to make such payments to the Trustee and, in the event that the Trustee
shall consent to the making of such payments directly to the Holders, to pay the
Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 607.

                  Nothing herein contained shall be deemed to authorize the
Trustee to authorize or consent to or accept or adopt on behalf of any Holder
any plan of reorganization, arrangement, adjustment or composition affecting the
Securities or the rights of any Holder thereof, or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding; provided,
however, that the Trustee may vote on behalf of the Holders in any election of a
trustee in bankruptcy or other Person performing similar functions.

         Section 505.      Trustee May Enforce Claims without Possession of
Securities.

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

         Section 506.      Application of Money Collected.

                  Any money collected by the Trustee pursuant to this Article or
otherwise on behalf of the Holders or the Trustee pursuant to this Article or

lieu of any proceeding contemplated by this

and upon surrender thereof if fully paid:

                  FIRST: To the payment of all amounts due the Trustee under
Section 607;

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

                  THIRD: The balance, if any, to the Person or Persons entitled
thereto, including the Company, provided that all sums due and owing to the
Holders and the Trustee have been paid in full as required by this Indenture.

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

         Section 507.      Limitation on Suits.

any proceeding, judicial or otherwise, with respect to this Indenture or the
Securities, or for the appointment of a receiver or trustee, or for any other
remedy hereunder, unless

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

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

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

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

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

it being understood and intended that no one or more Holders shall have any
right in any manner whatever by virtue of, or by availing of, any provision of
this Indenture, any Security or any Guarantee to affect, disturb or prejudice
the rights of any other Holders, or to obtain or to seek to

                                       - -
<PAGE>
obtain priority or preference over any other Holders or to enforce any right
under this Indenture, any Security or any Guarantee, except in the manner
provided in this Indenture and for the equal and ratable benefit of all the
Holders.

         Section 508.      Unconditional Right of Holders to Receive Principal,
Premium and Interest.

                  Notwithstanding any other provision in this Indenture,
including Section 507 without limitation, the Holder of any Security shall have
the right based on the terms stated herein, which is absolute and unconditional,
to receive payment of the principal of, premium, if any, and (subject to Section
309) interest on such Security on the respective Stated Maturities expressed in
such Security (or, in the case of redemption or repurchase, on the Redemption
Date or the repurchase date) and to institute suit for the enforcement of any
such payment, and such rights shall not be impaired without the consent of such
Holder.

         Section 509.      Restoration of Rights and Remedies.

                  If the Trustee or any Holder has instituted any proceeding to
enforce any right or remedy under this Indenture or any Guarantee 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 the Company, any Guarantor, any other obligor on the Securities, the
Trustee and the Holders shall, subject to any determination in such proceeding,
be restored severally and respectively to their former positions hereunder, and
thereafter all rights and remedies of the Trustee and the Holders shall continue
as though no such proceeding had been instituted.

         Section 510.      Rights and Remedies Cumulative.

                  No right or remedy herein conferred upon or reserved to the
Trustee or to the Holders is intended to be exclusive of any other right or
remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the
concurrent assertion or employment of any other appropriate right or remedy.

         Section 511.    Delay or Omission Not Waiver.

                  No delay or omission of the Trustee or of any Holder of any
Security to exercise any right or remedy accruing upon any Event of Default
shall impair any such right or remedy or constitute a waiver of any such Event
of Default or an acquiescence therein. Every right and remedy given by this
Article or by law to the Trustee or to the Holders may be exercised from time to
time, and as often as may be deemed expedient, by the Trustee or by the Holders,
as the case may be.

         Section 512.      Control by Holders.

                  The Holders of not less than a majority in aggregate principal
amount of the Outstanding Securities shall have the right to direct the time,
method and place of conducting

                                       - -
<PAGE>
any proceeding for exercising any remedy available to the Trustee, or exercising
any trust or power conferred on the Trustee, provided that

                  (a)      such direction shall not be in conflict with any rule
of law or with this Indenture (including, without limitation, Section 507) or
any Guarantee, expose the Trustee to personal liability, or be unduly
prejudicial to Holders not joining therein; and

                  (b)      subject to the provisions of Section 315 of the Trust
Indenture Act, the Trustee may take any other action deemed proper by the
Trustee which is not inconsistent with such direction.

                  Prior to taking any action hereunder, the Trustee shall be
entitled to indemnification from the Holders satisfactory to it in its sole
discretion against all losses and expenses caused by taking or not taking such
action.

         Section 513.      Waiver of Past Defaults.

                  The Holders of not less than a majority in aggregate principal
amount of the Outstanding Securities may on behalf of the Holders of all
Outstanding Securities waive any past Default hereunder and its consequences,
except:

                  (a)      an uncured Default in the payment of the principal
of, premium, if any, or interest on any Security (which may only be waived with
the consent of each Holder of Securities effected); or

                  (b)      a Default in respect of a covenant or a provision
hereof which under this Indenture cannot be modified or amended without the
consent of the Holder of each Security Outstanding affected by such modification
or amendment.

                  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 impair any right consequent thereon.

         Section 514.      Undertaking for Costs.

                  All parties to this Indenture agree, and each Holder of any
Security by his acceptance thereof shall be deemed to have agreed, that any
court may in its discretion require, 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, suffered or omitted by it as Trustee, the filing by any party
litigant in such suit of an undertaking to pay the costs of such suit, and that
such court may in its discretion assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in such suit, having due regard to
the merits and good faith of the claims or defenses made by such party litigant,
but the provisions of this Section shall not apply to any suit instituted by the
Trustee, to a suit by a Holder pursuant to Section 508 hereof or to any suit
instituted by any Holder, or group of Holders, holding in the aggregate more
than 10% in principal amount of the Outstanding Securities, or to any suit
instituted by any Holder for the enforcement of the payment of the principal of,
premium, if any, or interest on, any Security on or after the

                                       - -
<PAGE>
respective Stated Maturities expressed in such Security (or, in the case of
redemption, on or after the Redemption Date).

         Section 515.      Waiver of Stay, Extension or Usury Laws.

                  Each of the Company and the 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 or other law wherever enacted, now or at
any time hereafter in force, which would prohibit or forgive the Company or any
Guarantor from paying all or any portion of the principal of, premium, if any,
or interest on the Securities contemplated herein or in the Securities or which
may affect the covenants or the performance of this Indenture; and each of the
Company and the 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 516.      Remedies Subject to Applicable Law.

                  All rights, remedies and powers provided by this Article Five
may be exercised only to the extent that the exercise thereof does not violate
any applicable provision of law in the premises, and all the provisions of this
Indenture are intended to be subject to all applicable mandatory provisions of
law which may be controlling in the premises and to be limited to the extent
necessary so that they will not render this Indenture invalid, unenforceable or
not entitled to be recorded, registered or filed under the provisions of any
applicable law.

circumstances in the conduct of his own affairs;

                  (b)      except during the continuance of a Default or an
 Event of Default:

                           (1)      the Trustee need perform only those duties
                  as are specifically set forth in this Indenture and no
                  covenants or obligations shall be implied in this Indenture
                  that are adverse to the Trustee; and

                          (2)       in the absence of bad faith or willful
                  misconduct on its part, the Trustee may conclusively rely, as
                  to the truth of the statements and the correctness of the
                  opinions expressed therein, upon certificates or opinions
                  furnished to the

                  requirements of this Indenture;

                  (c)      the Trustee may not be relieved from liability for

its own willful misconduct, except that:

                           (1)      this Subsection (c) does not limit the

                  error of judgment made in good faith by a Responsible Officer,
                  unless it is proved that the Trustee was grossly negligent in
                  ascertaining the pertinent facts; and

                           (3)      the Trustee shall not be liable with respect
                  to any action it takes or omits to take in good faith, in

                  principal amount of Outstanding Securities relating to the
                  time, method and place of conducting any proceeding for any
                  remedy available to the Trustee, or exercising any trust or
                  power confirmed upon the Trustee under this Indenture;

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 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;

                  (e)      whether or not therein expressly so provided, every
provision of this Indenture that in any way relates to the Trustee is subject to
Subsections (a), (b), (c) and (d) of this Section 601; and

receives notice of the occurrence and continuance of any Default, the Trustee
shall transmit by mail to all Holders notice of such Default hereunder known to
the Trustee, unless such Default shall have been cured or waived; provided,
however, that, except in the case of a Default in the payment of the principal

in withholding such notice if and so long as a trust committee of Responsible
Officers of the Trustee in good faith determines that the withholding of such
notice is in the interest of the Holders.

                  All moneys received by the Trustee shall, until used or
applied as herein provided, be held in trust for the purposes for which they
were received, but need not be segregated from

other funds except to the extent required by mandatory provisions of law. Except
for funds or securities deposited with the Trustee pursuant to Article Four, the
Trustee shall be required to invest all moneys received by the Trustee, until
used or applied as herein provided, in Temporary Cash Investments in accordance
with the written directions of the Company. The Trustee is hereby authorized, in
making or disposing of any investment permitted by this Indenture, to deal with
itself (in its individual capacity) or with any one or more of its affiliates,
whether it or such affiliate is acting as a subagent of the Trustee or for any
third person or dealing as principal for its own account.

         Section 607.      Compensation and Indemnification of Trustee and Its
Prior Claim.

                  The Company covenants and agrees to pay to the Trustee from
time to time, and the Trustee shall be entitled to, reasonable compensation for
all services rendered by it hereunder in accordance with the written agreements
between the Company and the Trustee (which compensation shall not be limited by
any provision of law in regard to the compensation of a trustee of an express
trust) and the Company covenants and agrees to pay or reimburse the Trustee and
each predecessor Trustee upon its request for all reasonable expenses,
disbursements and advances incurred or made by or on behalf of the Trustee in
accordance with any of the provisions of this Indenture (including the
reasonable compensation and the expenses and disbursements of its counsel and of
all agents and other persons not regularly in its employ) except any such
expense, disbursement or advance as may arise from its gross negligence, bad
faith or willful misconduct. The Company also covenants and agrees to indemnify
the Trustee and each predecessor Trustee for, and to hold it harmless against,
any claim, loss, liability, tax, assessment, governmental charge (other than
taxes applicable to the Trustee's compensation hereunder) or expense incurred
without gross negligence, bad faith or willful misconduct on its part, arising
out of or in connection with the acceptance or administration of this Indenture
or the trusts hereunder and its duties hereunder, including the costs of
enforcement of this Section 607 and the costs and expenses of defending itself
against or investigating any claim or liability in connection with the exercise
or performance of any of its powers or duties hereunder. The obligations of the
Company under this Section 607 to compensate and indemnify the Trustee and each
predecessor Trustee and to pay or reimburse the Trustee and each predecessor
Trustee for reasonable expenses, disbursements and advances shall constitute an
additional obligation hereunder and shall survive the satisfaction and discharge
of this Indenture and the resignation or removal of the Trustee and each
predecessor Trustee.

                  To secure the Company's payment obligations in this Section,
the Trustee shall have a lien prior to the Securities on all money or property
held or collected by the Trustee other than money or property held in trust to
pay principal of and interest on particular Securities. Such lien shall survive
the satisfaction and discharge of this Indenture and the resignation or removal
of the Trustee and each predecessor Trustee.

                  When the Trustee incurs expenses or renders services after the
occurrence of a Default specified in Sections 501(g) or (h) with respect to the
Company, the expenses and the compensation for the services (including the fees
and expenses of its agents and counsel) are intended to constitute expenses of
administration under Bankruptcy Law.

         Section 608.      Conflicting Interests.

                  The Trustee shall comply with the provisions of Section 310(b)
of the Trust Indenture Act; provided, however, that there shall be excluded from
the operation of Section 310(b)(1) of the Trust Indenture Act any indenture or
indentures under which other securities or certificates of interest or
participation in other securities of the Company are outstanding if the
requirements for such exclusion set forth in Section 310(b)(l) of the Trust
Indenture Act are met.

         Section 609.      Trustee Eligibility.

                  There shall at all times be a Trustee hereunder which shall be
eligible to act as trustee under Trust Indenture Act Section 310(a) and which
shall have a combined capital and surplus of at least $50,000,000, as set forth
in its most recent published annual report of condition. If at any time the
Trustee shall cease to be eligible in accordance with the provisions of this
Section 609, the Trustee shall resign immediately in the manner and with the
effect hereinafter specified in this Article.

         Section 610.      Resignation and Removal; Appointment of Successor
Trustee.

                  (a)      No resignation or removal of the Trustee and no
appointment of a successor trustee pursuant to this Article shall become
effective until the acceptance of appointment by the successor trustee under
Section 611.

                  (b)      The Trustee, or any trustee or trustees hereafter
appointed, may at any time resign by giving written notice thereof to the
Company. Upon receiving such notice of resignation, the Company shall promptly
appoint a successor trustee by written instrument executed by authority of the
Board of Directors of the Company, a copy of which shall be delivered to the
resigning Trustee and a copy to the successor trustee. If an instrument of
acceptance by a successor trustee shall not have been delivered to the Trustee
within 60 days after the giving of such notice of resignation, the resigning
Trustee may, or any Holder who has been a bona fide Holder of a Security for at
least six months may, on behalf of himself and all others similarly situated,
petition any court of competent jurisdiction for the appointment of a successor
trustee. Such court may thereupon, after such notice, if any, as it may deem
proper, appoint and prescribe a successor trustee.

                  (c)      The Trustee may be removed at any time for any cause
or for no cause by an Act of the Holders of not less than a majority in
aggregate principal amount of the Outstanding Securities, delivered to the
Trustee and to the Company.

                  (d)      If at any time:

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

                           (2)      the Trustee shall cease to be eligible under
                  Section 609 and shall fail to resign after written request
                  therefor by the Company or by any Holder who has been a bona
                  fide Holder of a Security for at least six months, or

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

then, in any case, (i) the Company by a Board Resolution may remove the Trustee,
or (ii) subject to Section 514, the Holder of any Security who has been a bona
fide Holder of a Security for at least six months may, on behalf of himself and
all others similarly situated, petition any court of competent jurisdiction for
the removal of the Trustee and the appointment of a successor trustee. Such
court may thereupon, after such notice, if any, as it may deem proper and
prescribe, remove the Trustee and appoint a successor trustee.

                  (e)      If the Trustee shall resign, be removed or become
incapable of acting, or if a vacancy shall occur in the office of Trustee for
any cause, the Company, by a Board Resolution, shall promptly appoint a
successor trustee and shall comply with the applicable requirements of Section
611. If, within 60 days after such resignation, removal or incapability, or the
occurrence of such vacancy, the Company has not appointed a successor Trustee, a
successor trustee may be appointed by the Act of the Holders of a majority in
principal amount of the Outstanding Securities delivered to the Company and the
retiring Trustee (or a court may appoint and prescribe a successor trustee
pursuant to clause 610(b) hereof). Such successor trustee so appointed shall
forthwith upon its acceptance of such appointment become the successor trustee.
If no successor trustee shall have been so appointed by the Company or the
Holders of the Securities and accepted appointment in the manner hereinafter
provided, the Trustee or the Holder of any Security who has been a bona fide
Holder for at least six months may, subject to Section 514, on behalf of himself
and all others similarly situated, petition any court of competent jurisdiction
for the appointment of a successor trustee.

                  (f)      The Company shall give notice of each resignation and
each removal of the Trustee and each appointment of a successor trustee by
mailing written notice of such event by first-class mail, postage prepaid, to
the Holders of Securities as their names and addresses appear in the Security
Register. Each notice shall include the name of the successor trustee and the
address of its Corporate Trust Office or agent hereunder.

         Section 611.      Acceptance of Appointment by Successor.

                  Every successor trustee appointed hereunder shall execute,
acknowledge and deliver to the Company and to the retiring Trustee an
instrument accepting such appointment, and thereupon the resignation or removal
of the retiring Trustee shall become effective and such successor trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee as if originally named
as Trustee hereunder; but, nevertheless, on the written request of the Company
or the successor trustee, upon payment of its charges pursuant to Section 607
then unpaid, such retiring Trustee shall pay over to the successor trustee all
moneys at the time held by it hereunder and shall execute and deliver an
instrument transferring to such successor trustee all such rights, powers,
duties and obligations. Upon request of any such successor trustee, the Company
shall execute any and all instruments for more fully and certainly vesting in
and confirming to such successor trustee all such rights and powers.

                  No successor trustee with respect to the Securities shall
accept appointment as provided in this Section 611 unless at the time of such
acceptance such successor trustee shall be eligible to act as trustee under the
provisions of Trust Indenture Act Section 310(a) and this Article Six and shall
have a combined capital and surplus of at least $50,000,000 as set forth in its
most recent applicable published annual report of condition.

                  Upon acceptance of appointment by any successor trustee as
provided in this Section 611, the Company shall give notice thereof to the
Holders of the Securities, by mailing such notice to such Holders at their
addresses as they shall appear on the Security Register. If the acceptance of
appointment is substantially contemporaneous with the appointment, then the
notice called for by the preceding sentence may be combined with the notice
called for by Section 610. If the Company fails to give such notice within 10
days after acceptance of appointment by the successor trustee, the successor
trustee shall cause such notice to be given at the expense of the Company.

         Section 612.      Merger, Conversion, Consolidation or Succession to
Business.

                  Any corporation into which the Trustee may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which the Trustee shall be a
party, or any corporation succeeding to all or substantially all of the
corporate trust business of the Trustee (including the trust created by this
Indenture) shall be the successor of the Trustee hereunder, provided that such
corporation shall be eligible under Trust Indenture Act Section 310(a) and this
Article Six.

                  In case at the time such successor to the Trustee shall
succeed to the trusts created by this Indenture any of the Securities shall have
been authenticated but not delivered, any such successor to the Trustee may
adopt the certificate of authentication of any predecessor Trustee and deliver
such Securities so authenticated; and, in case at that time any of the
Securities shall not have been authenticated, any successor to the Trustee may
authenticate such Securities either in the name of any predecessor hereunder or
in the name of the successor trustee; and in all such cases such certificate
shall have the full force which it is anywhere in the Securities or in this
Indenture provided that the certificate of the Trustee shall have; provided that
the right to adopt the certificate of authentication of any predecessor Trustee
or to authenticate Securities in the name of any predecessor Trustee shall apply
only to its successor or successors by merger, conversion or consolidation.

         Section 613.      Preferential Collection of Claims Against Company.

                  If and when the Trustee shall be or become a creditor of the
Company (or other obligor under the Securities), the Trustee shall be subject to
the provisions of the Trust Indenture Act regarding the collection of claims
against the Company (or any such other obligor). A Trustee who has resigned or
been removed shall be subject to Trust Indenture Act Section 311 (a) to the
extent indicated therein.

                  Until an amendment or waiver becomes effective, a consent to
it by a Holder of a Security is a continuing consent by the Holder and every
subsequent Holder of a Security or portion of a Security that evidences the same
Indebtedness as the consenting Holder's Security, even if a notation of the
consent is not made on any Security. However, any such Holder, or subsequent
Holder, may revoke the consent as to his Security or portion of a Security if
the Trustee receives the notice of revocation before the date the amendment or
waiver becomes effective. An amendment or waiver shall become effective in
accordance with its terms and thereafter bind every Holder.

         Section 1001.     Payment of Principal, Premium and Interest.

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

         Section 1002.     Maintenance of Office or Agency.

Indenture may be served. The office of an affiliate of the Trustee, State Street
Bank and Trust Company, N.A., at its corporate trust office initially located at

Company, unless the Company shall designate and maintain some other office or
agency for one or more of such purposes. The Company will give prompt written
notice to the Trustee of the location and any change in the location of any such
offices or agencies. If at any time the Company shall fail to maintain any such
required offices or agencies or shall fail to furnish the Trustee with the
address thereof, such presentations, surrenders, notices and demands may be made
or served at the office of the Trustee and the Company hereby appoints the
Trustee such agent as its agent to receive all such presentations, surrenders,
notices and demands.

                  The Company may from time to time designate one or more other
offices or agencies (in or outside of The City of New York) where the Securities
may be presented or surrendered for any or all such purposes, and may from time
to time rescind such designation. The Company will give prompt written notice to
the Trustee of any such designation or rescission and any change in the location
of any such office or agency.

                  The Trustee shall initially act as Paying Agent for the
Securities.

         Section 1003.     Money for Security Payments to Be Held in Trust.

                  If the Company or any of its Affiliates shall at any time act
as Paying Agent, it will, on or before each due date of the principal of,
premium, if any, or interest on any of the Securities, segregate and hold in
trust for the benefit of the Holders entitled thereto a sum sufficient to pay
the principal, premium, if any, or interest so becoming due until such sums
shall be paid to such Persons or otherwise disposed of as herein provided, and
will promptly notify the Trustee of its action or failure so to act.

                  If the Company or any of its Affiliates is not acting as

Agent a sum in same day funds sufficient to pay the principal, premium, if any,
or interest so becoming due, such sum to be held in trust for the benefit of the
Persons entitled to such principal, premium or interest, and (unless such Paying
Agent is the Trustee) the Company will promptly notify the Trustee of such
action or any failure so to act.

                  If the Company is not acting as Paying Agent, the Company will
cause each Paying Agent other than the Trustee to execute and deliver to the
Trustee an instrument in which such Paying Agent shall agree with the Trustee,
subject to the provisions of this Section, that such Paying Agent will:

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

                  (b)      give the Trustee notice of any Default by the Company
or any Guarantor (or any other obligor upon the Securities) in the making of any
payment of principal, premium, if any, or interest on the Securities;

                  (c)      at any time during the continuance of any such
Default, upon the written request of the Trustee, forthwith pay to the Trustee
all sums so held in trust by such Paying Agent; and

                  (d)      acknowledge, accept and agree to comply in all
aspects with the provisions of this Indenture relating to the duties, rights and
liabilities of such Paying Agent.

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

                  Any money deposited with the Trustee or any Paying Agent, or
then held by the Company, in trust for the payment of the principal of, premium,
if any, or interest on any Security and remaining unclaimed for two years after
such principal and premium, if any, or

                                       - -

interest has become due and payable shall promptly be paid to the Company on
Company Request, or (if then held by the Company) shall be discharged from such
trust; and the Holder of such Security shall thereafter, as an unsecured general
creditor, look only to the Company for payment thereof, and all liability of the
Trustee or such Paying Agent with respect to such trust money, and all liability
of the Company as trustee thereof, shall thereupon cease.

         Section 1004.     Corporate Existence.

                  Subject to Article Eight, the Company shall do or cause to be
done all things necessary to preserve and keep in full force and effect the
corporate existence and related rights and franchises (charter and statutory) of
the Company and each Restricted Subsidiary; provided, however, that the Company
shall not be required to preserve any such right or franchise or the corporate
existence of any such Restricted Subsidiary if the Board of Directors of the
Company shall determine that the preservation thereof is no longer necessary or
desirable in the conduct of the business of the Company and its Restricted
Subsidiaries as a whole and that the loss thereof would not reasonably be
expected to have a material adverse effect on the ability of the Company to
perform its obligations hereunder; and provided, further, however, that the
foregoing shall not prohibit a sale, transfer or conveyance of a Restricted
Subsidiary or any of its assets in compliance with the terms of this Indenture.

         Section 1005.     Payment of Taxes and Other Claims.

                  The Company shall pay or discharge or cause to be paid or
discharged, on or before the date the same shall become due and payable, (a) all
taxes, assessments and governmental charges levied or imposed upon the Company
or any of its Restricted Subsidiaries shown to be due on any return of the
Company or any of its Restricted Subsidiaries or otherwise assessed or upon the
income, profits or property of the Company or any of its Restricted Subsidiaries
if failure to pay or discharge the same could reasonably be expected to have a
material adverse effect on the ability of the Company or any Guarantor to
perform its obligations hereunder and (b) all lawful claims for labor, materials
and supplies, which, if unpaid, would by law become a Lien upon the property of
the Company or any of its Restricted Subsidiaries, except for any Lien permitted
to be incurred under Section 1011, if failure to pay or discharge the same
could reasonably be expected to have a material adverse effect on the ability of
the Company or any Guarantor to perform its obligations hereunder; provided,
however, 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 whose amount,
applicability or validity is being contested in good faith by appropriate
proceedings properly instituted and diligently conducted and in respect of which
appropriate reserves (in the good faith judgment of management of the Company)
are being maintained in accordance with GAAP.

         Section 1006.     Maintenance of Properties.

                  The Company shall cause all material properties owned by the
Company and its Restricted Subsidiaries or used or held for use 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 (ordinary wear
and tear excepted) 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 reasonable judgment of the Company may be
consistent with sound business practice and necessary so that the business
carried on in connection therewith may be properly conducted at all times;
provided, however, that nothing in this Section shall prevent the Company from
discontinuing the maintenance of any of such properties if such discontinuance
is, in the reasonable judgment of the Company, not reasonably expected to have a
material adverse effect on the ability of the Company to perform its obligations
hereunder; and provided, further, however, that the foregoing shall not prohibit
a sale, transfer or conveyance of a Restricted Subsidiary or any of its
properties or assets in compliance with the terms of this Indenture.

         Section 1007.     Maintenance of Insurance.

                  The Company shall at all times keep all of its and its
Restricted Subsidiaries' properties which are of an insurable nature insured
with insurers, believed by the Company in good faith to be financially sound and
responsible, against loss or damage to the extent that property of similar
character is usually so insured by corporations similarly situated and owning
like properties in the same general geographic areas in which the Company and
its Restricted Subsidiaries operate, except where the failure to do so could not
reasonably be expected to have a material adverse effect on the ability of the
Company and its Restricted Subsidiaries to perform their obligations hereunder.

         Section 1008.     Limitation on Indebtedness.

                  (a)      The Company will not, and will not cause or permit
any of its Restricted Subsidiaries to, create, issue, incur, assume, guarantee
or otherwise in any manner become directly or indirectly liable for the payment
of or otherwise incur, contingently or otherwise (collectively, "incur"), any
Indebtedness (including any Acquired Indebtedness), unless (i) such Indebtedness
is incurred by the Company or any Guarantor or constitutes Acquired Indebtedness
of a Restricted Subsidiary and, in each case, the Company's Consolidated Fixed
Charge Coverage Ratio for the most recent four full fiscal quarters for which
financial statements are available immediately preceding the incurrence of such
Indebtedness taken as one period is at least equal to or greater than 2:l on or
prior to December 26, 2004 and at least equal to or greater than 2.5:1
thereafter, or (ii) such Indebtedness is incurred by a Restricted Subsidiary
that is not a Guarantor and the Company's Consolidated Fixed Charge Coverage
Ratio for the most recent four full fiscal quarters for which financial
statements are available immediately preceding the incurrence of such
Indebtedness taken as one period is at least equal to or greater than 3:1.

                  (b)      Notwithstanding the foregoing, the Company and, to
the extent specifically set forth below, the Restricted Subsidiaries, may incur
each and all of the following (collectively, the "Permitted Indebtedness"):

                  (i)      Indebtedness of the Company or any Guarantor (and,

         Indebtedness incurred pursuant to paragraph (a) of this Section 1008
         and clauses (ii) and (iii) (other than Indebtedness pursuant to the
         6.8% Notes and the Zero Coupon Convertible Debentures) of this
         paragraph (b), including any successive refinancings so long as the
         borrower under such refinancing is the Company or, if not the Company,
         the same as the borrower of the Indebtedness being refinanced and the
         aggregate principal amount of Indebtedness represented thereby (or if
         such Indebtedness provides for an amount less than the principal amount
         thereof to be due and payable upon a declaration of acceleration of the
         maturity thereof, the original issue price of such Indebtedness plus
         any accreted value attributable thereto since the original issuance of
         such Indebtedness) is not increased by

                                       - -

         such refinancing plus the lesser of (A) the stated amount of any
         premium or other payment required to be paid in connection with such a
         refinancing pursuant to the terms of the Indebtedness being refinanced
         or (B) the amount of premium or other payment actually paid at such
         time to refinance the Indebtedness, plus, in either case, the amount of
         expenses of the Company incurred in connection with such refinancing;
         and

                  (xvii)   Indebtedness of the Company or any Restricted
         Subsidiary in addition to that described in clauses (i) through (xvi)
         above, and any renewals, extensions, substitutions, refinancings or
         replacements of such Indebtedness, so long as the aggregate principal
         amount of all such Indebtedness shall not exceed $40 million
         outstanding at any one time in the aggregate.

                  (c)      For purposes of determining compliance with this
Section 1008, in the event that an item of Indebtedness meets the criteria of
more than one of the types of Indebtedness permitted by this Section 1008, the
Company in its sole discretion shall classify or reclassify such item of
Indebtedness and only be required to include the amount of such Indebtedness as
one of such types; provided that Indebtedness under the Credit Agreement and the
Company's existing receivables securitization facility which is in existence
following the Issue Date, and any renewals, extensions, substitutions,
refundings, refinancings or replacements thereof, in an amount not in excess of
the amount permitted to be incurred pursuant to clause (i) of paragraph (b)
above, shall be deemed to have been incurred pursuant to clause (i) of paragraph
(b) above rather than paragraph (a) above.

                  (d)      Indebtedness permitted by this Section 1008 need not
be permitted solely by reference to one provision permitting such Indebtedness
but may be permitted in part by one such provision and in part by one or more
other provisions of this Section 1008 permitting such Indebtedness.

                  (e)      Accrual of interest, accretion or amortization of
original issue discount and the payment of interest on any Indebtedness in the
form of additional Indebtedness with the same terms, the payment of dividends on
any Redeemable Capital Stock of the Company or a Restricted Subsidiary of the
Company in the form of additional shares of the same class of Redeemable Capital
Stock, and the payment of dividends on any Preferred Stock of a Restricted
Subsidiary in the form of additional shares of the same class of Preferred Stock
of a Restricted Subsidiary or in other Qualified Capital Stock of such
Restricted Subsidiary will not be deemed to be an incurrence of Indebtedness for
purposes of this Section 1008; provided, in each such case, that the amount
thereof as accrued (other than any payment in Qualified Capital Stock) is
included in the Consolidated Fixed Charge Coverage Ratio of the Company.

                  (f)      For purposes of determining compliance with any
dollar-denominated restriction on the incurrence of Indebtedness denominated in
a foreign currency, the dollar- equivalent principal amount of such Indebtedness
incurred pursuant thereto shall be calculated based on the relevant currency
exchange rate in effect on the date that such Indebtedness was incurred.

                  (g)      If Indebtedness is secured by a letter of credit that
serves only to secure such Indebtedness, then the total amount deemed incurred
shall be equal to the greater of (x) the

                                       - -
<PAGE>
principal of such Indebtedness and (y) the amount that may be drawn under such
letter of credit.

                  (h)      The amount of Indebtedness issued at a price less
than the amount of the liability thereof shall be determined in accordance with
GAAP.

Owned Restricted Subsidiary) unless such transaction or series of related
transactions is entered into in good faith and in writing and (1) such

profits therefrom, unless the Securities (or a Guarantee in the case of Liens of
a Guarantor) are directly secured equally and ratably with (or, in the case of
Subordinated Indebtedness, prior or senior thereto, with the same relative
priority as the Securities shall have with respect to such Subordinated
Indebtedness) the obligation or liability secured by such Lien except for Liens

         (A)      securing any Indebtedness which became Indebtedness pursuant
                  to a transaction permitted under Article Eight herein or

                  (including any assumption, guarantee or other liability with
                  respect thereto by any Restricted Subsidiary) and which

                  the Company incurred in connection with such refinancing,

provided, however, that in the case of clauses (A) and (B), any such Lien only
extends to the assets that were subject to such Lien securing such Indebtedness
prior to the related acquisition by the Company or its Restricted Subsidiaries.

                  Notwithstanding the foregoing, any Lien securing the
Securities granted pursuant to this covenant shall be automatically and
unconditionally released and discharged upon the release by the holders of the
Pari Passu Indebtedness or Subordinated Indebtedness described above of their
Lien on the property or assets of the Company or any Restricted Subsidiary
(including any deemed release upon payment in full of all obligations under such
Indebtedness), at such time as the holders of all such Pari Passu Indebtedness
or Subordinated Indebtedness also release their Lien on the property or assets
of the Company or such Restricted Subsidiary, or upon any sale, exchange or
transfer to any Person of the property or assets secured by such Lien, or of all
of the Capital Stock held by the Company or any Restricted Subsidiary in, or all
or substantially all the assets of, any Restricted Subsidiary creating such
Lien.

                  (b)      However, if a Fall Away Event has occurred, then,
subject to Section 1023 herein, thereafter (i) the Company shall no longer be
subject to paragraph (a) of this Section 1011 and (ii) the Company will not, and
will not permit any Restricted Subsidiary to, incur any Lien to secure
Indebtedness without making, or causing such Restricted Subsidiary to make,
effective provision for securing the Securities on a subordinated (second
priority) basis for so long as such Indebtedness is so secured. The foregoing
restrictions of this paragraph (b) will not apply to:

                  (1)      any Lien existing on (or securing Indebtedness
         committed to but not outstanding on) the date of the Fall Away Event
         (which Lien in either case was not created in connection with, or in
         contemplation of, such Fall Away Event);

                  (2)      any Lien in favor of only the Company or a Restricted
         Subsidiary;

                  (3)      any Lien on property of a Person existing immediately
         prior to the time such Person is merged with or into or consolidated
         with the Company or any of its Restricted Subsidiaries or otherwise
         becomes a Restricted Subsidiary of the Company (provided that such Lien
         is not incurred in anticipation of such transaction and does not extend
         beyond the property subject thereto, or secure any Indebtedness that is
         not secured thereby, immediately prior to such transaction);

                  (4)      any Lien on property (or on the Capital Stock of the
         entity that owns property) existing immediately prior to the time of
         acquisition thereof (provided that such Lien is not incurred in
         anticipation of such transaction and does not extend beyond the
         property subject thereto, or secure any Indebtedness that is not
         secured thereby, immediately prior to such transaction);

                  (5)      any Lien on property or assets securing all or any
         portion of the purchase price thereof or securing all or any portion of
         the cost of construction or alteration of or improvement on any
         property or assets created or assumed contemporaneously with, or

                                       - -
<PAGE>
         within 90 days after, such acquisition or completion of such
         construction or improvement (provided that such Lien does not extend to
         any other property or assets and secures Indebtedness in an amount that
         does not exceed such purchase price or cost of construction, alteration
         or improvement);.

                  (6)      Liens with respect to the payment of taxes,
         assessments or governmental charges in all cases which are not yet due
         or which are being contested in good faith by appropriate proceedings
         and with respect to which adequate reserves or other appropriate
         provisions are being maintained to the extent required by GAAP;

                  (7)      Liens of landlords arising by statute and Liens of
         suppliers, mechanics, carriers, materialmen, warehousemen or workmen
         and other Liens imposed by law created in the ordinary course of
         business for amounts not yet due or which are being contested in good
         faith by appropriate proceedings and with respect to which adequate
         reserves or other appropriate provisions are being maintained to the
         extent required by GAAP;

                  (8)      deposits made in the ordinary course of business in
         connection with worker's compensation, unemployment insurance or
         other types of social security benefits or to secure the performance of
         bids, tenders, sales, contracts (other than for the repayment of
         borrowed money) and surety, appeal, customs or performance bonds (or
         letters of credit or comparable instruments securing the Company's or a
         Restricted Subsidiary's performance and which are otherwise permitted
         by this Indenture);

                  (9)      encumbrances arising by reason of zoning
         restrictions, easements, licenses, reservations, covenants,
         rights-of-way, utility easements, building restrictions and other
         similar encumbrances on the use of real property that do not materially
         detract from the value of such real property or interfere with the
         ordinary conduct of the business conducted and proposed to be conducted
         at such real property;

                  (10)     encumbrances arising under leases or subleases of
         real property that do not in the aggregate materially detract from the
         value of such real property or interfere with the ordinary conduct of
         the business conducted and proposed to be conducted at such real
         property;

                  (11)     financing statements of a lessor's rights in and to
         personal property leased to such Person in the ordinary course of such
         Person's business;

                  (12)     other Liens if, after giving effect thereto, the sum
         of all Indebtedness secured by all Liens incurred pursuant to this
         clause (12) on or after the date of the Fall Away Event and outstanding
         at any one time, together with the Attributable Value of Sale Leaseback
         Transactions entered into on or after the date of the Fall Away Event
         pursuant to Section 1020 hereof and outstanding at any one time and
         otherwise prohibited by this Indenture, does not exceed 15% of the
         Company's Consolidated Net Tangible Assets; and

                  (13)     any extension, renewal, refunding or refinancing of
         any of the Liens referred to in sections (1) to (11) above or this
         section (13).

         Section 1012.     Limitation on Sale of Assets.

                  (a)      The Company will not, and will not cause or permit
any of its Restricted Subsidiaries to, directly or indirectly, consummate an
Asset Sale unless (1) at least 75% of the consideration from such Asset Sale
other than Asset Swaps is received in cash and (2) the Company or such
Restricted Subsidiary receives consideration at the time of such Asset Sale at
least equal to the Fair Market Value of the shares or assets subject to such
Asset Sale (as determined by the Board of Directors of the Company and evidenced
in a Board Resolution). The amount of any (A) Indebtedness (other than any
Subordinated Indebtedness) of the Company or any Restricted Subsidiary that is
actually assumed by the transferee in such Asset Sale and from which the Company
and the Restricted Subsidiaries are fully released shall be deemed to be cash
for purposes of determining the percentage of the consideration received by the
Company or the Restricted Subsidiaries in cash and (B) notes, securities or
other similar obligations received by the Company or the Restricted Subsidiaries
from such transferee that are immediately converted, sold or exchanged (or are
converted, sold or exchanged within thirty days of the related Asset Sale) by
the Company or the Restricted Subsidiaries into cash shall be deemed to be cash,
in an amount equal to the net cash proceeds realized upon such conversion, sale
or exchange for purposes of determining the percentage of the consideration
received by the Company or the Restricted Subsidiaries in cash. In addition, the
amount of any Designated Non-cash Consideration received by the Company or any
of its Restricted Subsidiaries in the Asset Sale shall be deemed "cash" for
purposes of paragraph (a)(l) of this Section 1012.

                  (b)      All or a portion of the Net Cash Proceeds of any
Asset Sale may be applied by the Company or a Restricted Subsidiary, to the
extent the Company or such Restricted Subsidiary elects (or is required by the
terms of any Senior Indebtedness or Senior Guarantor Indebtedness): (i) to
prepay permanently or repay permanently any Senior Indebtedness or Senior
Guarantor Indebtedness then outstanding as required by the terms thereof (and in
the case of any such Indebtedness under a revolving credit facility, effect a
permanent reduction in the availability under such revolving credit facility),
or (ii) if the Company determines not to apply such Net Cash Proceeds to the
permanent repayment or permanent prepayment of such Senior Indebtedness or
Senior Guarantor Indebtedness, or if no such Senior Indebtedness or Senior
Guarantor Indebtedness is then outstanding, within 365 days of the Asset Sale,
to invest the Net Cash Proceeds in properties and other assets that (as
determined by the Board of Directors of the Company) replace the properties and
assets that were the subject of the Asset Sale or in properties and assets that
will be used in the businesses of the Company or its Restricted Subsidiaries
existing on the date of this Indenture or in businesses reasonably related
thereto. The amount of such Net Cash Proceeds not used or invested in accordance
with the preceding clauses (i) and (ii) within 365 days of the Asset Sale
constitutes "Excess Proceeds."

                  (c)      When the aggregate amount of Excess Proceeds exceeds
$20 million or more, the Company will apply the Excess Proceeds to the repayment
of the Securities and any other Pari Passu Indebtedness outstanding with similar
provisions requiring the Company to make an offer to purchase such Indebtedness
with the proceeds from any Asset Sale as follows: (A) the Company will make an
offer to purchase (an "Offer") from all holders of the Securities in accordance
with the procedures set forth in this Indenture in the maximum principal amount
(expressed as a multiple of $1,000) of Securities that may be purchased out of
an amount (the "Security Amount") equal to the product of such Excess Proceeds
multiplied by a fraction, the

                                       - -
<PAGE>
numerator of which is the outstanding principal amount of the Securities, and
the denominator of which is the sum of the outstanding principal amount (or
accreted value in the case of Indebtedness issued with original issue discount)
of the Securities and such Pari Passu Indebtedness (subject to proration in the
event such amount is less than the aggregate Offered Price (as defined herein)
of all Securities tendered) and (B) to the extent required by such Pari Passu
Indebtedness to permanently reduce the principal amount of such Pari Passu
Indebtedness (or accreted value in the case of Indebtedness issued with original
issue discount), the Company will make an offer to purchase or otherwise
repurchase or redeem Pari Passu Indebtedness (a "Pari Passu Offer") in an amount
(the "Pari Passu Debt Amount") equal to the excess of the Excess Proceeds over
the Security Amount; provided that in no event will the Company be required to
make a Pari Passu Offer in a Pari Passu Debt Amount exceeding the principal
amount (or accreted value) of such Pari Passu Indebtedness plus the amount of
any premium required to be paid to repurchase such Pari Passu Indebtedness. The
offer price for the Securities tendered will be payable in cash in an amount
equal to 100% of the principal amount of the Securities tendered plus accrued
and unpaid interest, if any, to the date (the "Offer Date") such Offer is
consummated (the "Offered Price"), in accordance with the procedures set forth
in this Indenture. To the extent that the aggregate Offered Price of the
Securities tendered pursuant to the Offer is less than the Security Amount
relating thereto, the Company may use any remaining Excess Proceeds for general
corporate purposes. If the aggregate principal amount of Securities surrendered
by holders thereof exceeds the amount of the Security Amount, the Trustee shall
select the Securities to be purchased on a pro rata basis. Upon the completion
of the purchase of all the Securities tendered pursuant to an Offer, the amount
of Excess Proceeds, if any, shall be reset at zero for purposes of this
Indenture governing the Securities.

                  (d)      If the Company becomes obligated to make an Offer
pursuant to clause (c) above, the Securities shall be purchased by the Company,
at the option of the holders thereof, in whole or in part in integral multiples
of $1,000, on the Offer Date, which shall be fixed by the Company on a Business
Day that is not earlier than 30 days and not later than 60 days from the date
the notice of the Offer is given to holders, or such later date as may be
necessary for the Company to comply with the requirements under the Exchange
Act.

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

                  (f)      Subject to paragraph (e) above, within 30 days after
the date on which the amount of Excess Proceeds equals or exceeds $20 million,
the Company shall send or cause to be sent by first-class mail, postage prepaid,
to the Trustee and to each Holder, at his address appearing in the Security
Register, a notice stating or including:

                           (1)      that the Holder has the right to require the
                  Company to repurchase, subject to proration, such Holder's
                  Securities at the Offered Price;

                           (2)      the Offer Date;

                           (3)      the procedures that a Holder must follow
                  in order to have his Securities purchased in accordance with
                  paragraph (c) of this Section;

                                       - -
<PAGE>
                           (4)      such information, if any, concerning the
                  business of the Company which the Company in good faith
                  believes will enable such Holders to make an informed
                  investment decision regarding the Offer;

                           (5)      the Offered Price;

                           (6)      the names and addresses of the Paying Agent
                  and the offices or agencies referred to in Section 1002;

                           (7)      that Securities must be surrendered on or
                  prior to the Offer Date to the Paying Agent at the office of
                  the Paying Agent or to an office or agency referred to in
                  Section 1002 to collect payment;

                           (8)      that any Securities not tendered will
                  continue to accrue interest and that unless the Company
                  defaults in the payment of the Offered Price, any Security
                  accepted for payment pursuant to the Offer shall cease to
                  accrue interest on and after the Offer Date;

                           (9)      the procedures for withdrawing a tender; and

                           (10)     that the Offered Price for any Security
                  which has been properly tendered and not withdrawn and which
                  has been accepted for payment pursuant to the Offer will be
                  paid promptly following the Offered Date.

                  (g)      Holders electing to have Securities purchased
hereunder will be required to surrender such Securities at the address specified
in the notice prior to the Offer Date. Holders will be entitled to withdraw
their election to have their Securities purchased pursuant to this Section 1012
if the Company receives, not later than one Business Day prior to the Offer
Date, a telegram, telex, facsimile transmission or letter setting forth (1) the
name of the Holder, (2) the certificate number of the Security in respect of
which such notice of withdrawal is being submitted, (3) the principal amount of
the Security (which shall be $1,000 or an integral multiple thereof) delivered
for purchase by the Holder as to which such notice of withdrawal is being
submitted, (4) a statement that such Holder is withdrawing his election to have
such principal amount of such Security purchased, and (5) the principal
amount, if any, of such Security (which shall be $1,000 or an integral multiple
thereof) that remains subject to the original notice of the Offer and that has
been or will be delivered for purchase by the Company.

                  (h)      The Company shall (i) not later than the Offer Date,
accept for payment Securities or portions thereof tendered pursuant to the
Offer, (ii) not later than 10:00 a.m. (New York time) on the Business Day
following the Offer Date, deposit with the Trustee or with a Paying Agent an
amount of money in same day funds sufficient to pay the aggregate Offered Price
of all the Securities or portions thereof which have been so accepted for
payment and (iii) not later than 10:00 a.m. (New York time) on the Business Day
following the Offer Date, deliver to the Paying Agent an Officers' Certificate
stating the Securities or portions thereof accepted for payment by the Company.
The Paying Agent shall promptly mail or deliver to Holders of Securities so
accepted payment in an amount equal to the Offered Price of the Securities
purchased from each such Holder, and the Company shall execute and the Trustee
shall promptly authenticate and mail or deliver to such Holders a new Security
equal in principal

                                       - -
<PAGE>
amount to any unpurchased portion of the Security surrendered. Any Securities
not so accepted shall be promptly mailed or delivered by the Paying Agent at the
Company's expense to the Holder thereof.

                  The Trustee and the Paying Agent shall return to the Company
any cash that remains unclaimed for two years, together with interest or
dividends, if any, thereon, held by them for the payment of the Offered Price;
provided, however, that (x) to the extent that the aggregate amount of cash
deposited by the Company with the Trustee in respect of an Offer exceeds the
aggregate Offered Price of the Securities or portions thereof to be purchased,
then the Trustee shall hold such excess for the Company and (y) unless otherwise
directed by the Company in writing, promptly after the Business Day following
the Offer Date the Trustee shall return any such excess to the Company together
with interest or dividends, if any, thereon.

                  (i)      Upon receipt by the Company of the proper tender of
Securities, the Holder of the Security in respect of which such proper tender
was made shall (unless the tender of such Security is properly withdrawn)
thereafter be entitled to receive solely the Offered Price with respect to such
Security. Upon surrender of any such Security for purchase in accordance with
the foregoing provisions, such Security shall be paid by the Company at the
Offered Price; provided, however, that installments of interest whose Stated
Maturity is on or prior to the Offer Date shall be payable to the Person in
whose name the Securities (or any Predecessor Securities) is registered as such
on the relevant Regular Record Dates according to the terms and the provisions
of Section 309; provided, further, that Securities to be purchased are subject
to proration in the event the Security Amount is less than the aggregate Offered
Price of all Securities tendered for purchase, with such adjustments as may be
appropriate by the Trustee so that only Securities in denominations of $1,000
or integral multiples thereof, shall be purchased. If any Security tendered for
purchase in accordance with the provisions of this Section 1012 shall not be so
paid upon surrender thereof by deposit of funds with the Trustee or a Paying
Agent in accordance with paragraph (h) above, the principal thereof (and
premium, if any, thereon) shall, until paid, bear interest from the Offer Date
at the rate borne by such Security. Holders electing to have Securities
purchased will be required to surrender such Securities to the Paying Agent at
the address specified in the notice required by paragraph (f) of this Section
1012 at least one Business Day prior to the Offer Date. The Company shall
publicly announce the results of the Offer on or as soon as practicable after
the Offer Date.

         Section 1013.     Limitation on Issuances of Guarantees of and Pledges
for Indebtedness.

                  (a)      The Company will not cause or perrnit any Restricted
Subsidiary, other than a Guarantor, directly or indirectly, to secure the
payment of any Senior Indebtedness of the Company and the Company will not, and
will not permit any Restricted Subsidiary (other than a Guarantor) to, pledge
any intercompany notes representing obligations of any Restricted Subsidiary
(other than a Guarantor) or any Capital Stock of a Wholly Owned Restricted
Subsidiary (other than a Guarantor or a Securitization Entity and other than up
to 66 2/3% of the Capital Stock of a Foreign Subsidiary) to secure the payment
of any Senior Indebtedness unless in each case such Restricted Subsidiary
simultaneously executes and delivers a supplemental indenture to this Indenture
providing for a guarantee of payment of the Securities by such Restricted
Subsidiary, which guarantee shall be on the same terms as the guarantee of the
Senior Indebtedness (if a guarantee of Senior Indebtedness is granted by any
such Restricted

                                       - -
<PAGE>
Subsidiary) except that the guarantee of the Securities need not be secured and
shall be subordinated to the claims against such Restricted Subsidiary in
respect of Senior Indebtedness to the same extent as the Securities are
subordinated to Senior Indebtedness of the Company under this Indenture.

                  (b)      The Company will not cause or permit any Restricted
Subsidiary (which is not a Guarantor), directly or indirectly, to guarantee,
assume or in any other manner become liable with respect to any Indebtedness of
the Company or any Restricted Subsidiary unless such Restricted Subsidiary
simultaneously executes and delivers a supplemental indenture to this Indenture
providing for a Guarantee of the Securities on the same terms as the guarantee
of such Indebtedness except that (A) such Guarantee need not be secured unless
required pursuant to Section 1011 herein, (B) if such Indebtedness is by its
terms Senior Indebtedness, any such assumption, guarantee or other liability of
such Restricted Subsidiary with respect to such Indebtedness shall be senior to
such Restricted Subsidiary's Guarantee of the Securities to the same extent as
such Senior Indebtedness is senior to the Securities and (C) if such
Indebtedness is by its terms expressly subordinated to the Securities, any such
assumption, guarantee or other liability of such Restricted Subsidiary with
respect to such Indebtedness shall be subordinated to such Restricted
Subsidiary's Guarantee of the Securities at least to the same extent as such
Indebtedness is subordinated to the Securities. Notwithstanding this paragraph
(b), a Foreign Subsidiary may, directly or indirectly, to the extent otherwise
permitted by this Indenture, guarantee, assume or in any other manner become
liable with respect to any Indebtedness of another Foreign Subsidiary (which is
incurred in compliance with this Indenture) without complying with this
paragraph (b).

                  (c)      Notwithstanding the foregoing, any Guarantee
(including the initial Guarantees) by a Restricted Subsidiary of the Securities
shall provide by its terms that it (and all Liens securing the same) shall be
automatically and unconditionally released and discharged upon (i) any sale,
exchange or transfer, to any Person not an Affiliate of the Company, of all of
the Company's or any Restricted Subsidiary's Capital Stock in, or all or
substantially all the assets of, such Restricted Subsidiary, or the designation
of such Restricted Subsidiary as an Unrestricted Subsidiary, which transaction
is in compliance with the terms of this Indenture and such Restricted Subsidiary
is released from all guarantees, if any, by it of other Indebtedness of the
Company or any Restricted Subsidiaries or (ii) the release by the holders of the
Indebtedness of the Company described in paragraphs (a) and (b) above of their
security interest or their guarantee by such Restricted Subsidiary (including
any deemed release upon payment in full of all obligations under such
Indebtedness), at such time as (A) no other Indebtedness of the Company has been
secured or guaranteed by such Restricted Subsidiary, as the case may be, or (B)
the holders of all such other Indebtedness which is secured or guaranteed by
such Restricted Subsidiary also release their security interest in or guarantee
by such Restricted Subsidiary (including any deemed release upon payment in full
of all obligations under such Indebtedness).

         Section 1014.     Limitation on Senior Subordinated Indebtedness.

                  The Company will not, and will not permit or cause any
Guarantor to, directly or indirectly, create, incur, issue, assume, guarantee or
otherwise in any manner become directly or indirectly liable for or with respect
to or otherwise permit to exist any Indebtedness that is subordinate in right of
payment to any Indebtedness of the Company or such Guarantor, as the

                                       - -
<PAGE>
case may be, unless such Indebtedness is also pari passu with the Securities or
the Guarantee of such Guarantor or subordinated in right of payment to the
Securities or such Guarantee at least to the same extent as the Securities or
such Guarantee are subordinated in right of payment to Senior Indebtedness or
Senior Indebtedness of such Guarantor, as the case may be, as set forth in this
Indenture. Unsecured Indebtedness is not deemed to be subordinate or junior in
right of payment to secured Indebtedness merely because it is unsecured and
Indebtedness which has different security or different priorities in the same
security will not be deemed subordinate or junior in right of payment to secured
Indebtedness because of such differences.

         Section 1015.     Purchase of Securities upon a Change of Control.

                  (a)      If a Change of Control occurs, each holder of
Securities will have the right to require that the Company purchase all or any
part (in integral multiples of $1,000) of such holder's Securities pursuant to a
"Change of Control Offer." In the Change of Control Offer, the Company will
offer to purchase all of the Securities, at a purchase price (the "Change of
Control Purchase Price") in cash in an amount equal to 101% of the principal
amount of such Securities, plus accrued and unpaid interest, if any, to the date
of purchase (the "Change of Control Purchase Date") (subject to the rights of
holders of record on relevant record dates to receive interest due on an
interest payment date).

                  (b)      Within 30 days after any Change of Control or, at the
Company's option, prior to such Change of Control but after it is publicly
announced, the Company must notify the Trustee and give written notice of the
Change of Control to each holder of Securities, by first- class mail, postage
prepaid, at his address appearing in the security register. The notice must
state or include, among other things:

                           (1)      that a Change of Control has occurred or
                  will occur, the date of such event, and that such Holder has
                  the right to require the Company to repurchase such Holder's
                  Securities at the Change of Control Purchase Price;

                           (2)      such information, if any, concerning the
                  business of the Company which the Company in good faith
                  believes will enable such Holders to make an informed
                  investment decision regarding the Change of Control Offer;

                           (3)      that the Change of Control Offer is being
                  made pursuant to this Section 1015 and that all Securities
                  properly tendered pursuant to the Change of Control Offer will
                  be accepted for payment at the Change of Control Purchase
                  Price;

                           (4)      the Change of Control Purchase Date, which
                  shall be fixed by the Company on a Business Day no earlier
                  than 30 days nor later than 60 days from the date such notice
                  is mailed, or such later date as is necessary to comply with
                  requirements under the Exchange Act; provided that the Change
                  of Control Purchase Date may not occur prior to the Change of
                  Control;

                           (5)      the Change of Control Purchase Price;

<PAGE>
                           (6)      the names and addresses of the Paying Agent
                  and the offices or agencies referred to in Section 1002;

                           (7)      that Securities must be surrendered on or
                  prior to the Change of Control Purchase Date to the Paying
                  Agent at the office of the Paying Agent or to an office or
                  agency referred to in Section 1002 to collect payment;

                           (8)      that the Change of Control Purchase Price
                  for any Security which has been properly tendered and not
                  withdrawn will be paid promptly following the Change of
                  Control Offer Purchase Date;

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

                           (10)     that any Security not tendered will continue
                  to accrue interest; and

                           (11)     that, unless the Company defaults in the
                  payment of the Change of Control Purchase Price, any
                  Securities accepted for payment pursuant to the Change of
                  Control Offer shall cease to accrue interest after the Change
                  of Control Purchase Date.

                  (c)      Upon receipt by the Company of the proper tender of
Securities, the Holder of the Security in respect of which such proper tender
was made shall (unless the tender of such Security is properly withdrawn)
thereafter be entitled to receive solely the Change of Control Purchase Price
with respect to such Security. Upon surrender of any such Security for purchase
in accordance with the foregoing provisions, such Security shall be paid by the
Company at the Change of Control Purchase Price; provided, however, that
installments of interest whose Stated Maturity is on or prior to the Change of
Control Purchase Date shall be payable to the Person in whose name the
Securities (or any Predecessor Securities) is registered as such on the relevant
Regular Record Dates according to the terms and the provisions of Section 309.
If any Security tendered for purchase in accordance with the provisions of this
Section 1015 shall not be so paid upon surrender thereof, the principal thereof
(and premium, if any, thereon) shall, until paid, bear interest from the Change
of Control Purchase Date at the rate borne by such Security. Holders electing to
have Securities purchased will be required to surrender such Securities to the
Paying Agent at the address specified in the Change of Control Purchase Notice
at least one Business Day prior to the Change of Control Purchase Date. The
Company shall publicly announce the results of the Change of Control Offer on or
as soon as practicable after the Change of Control Purchase Date.

                  (d)      The Company shall (i) not later than the Change of
Control Purchase Date, accept for payment Securities or portions thereof
tendered pursuant to the Change of Control Offer, (ii) not later than 10:00 a.m.
(New York time) on the Business Day following the Change of Control Purchase
Date, deposit with the Trustee or with a Paying Agent an amount of money in same
day funds sufficient to pay the aggregate Change of Control Purchase Price of
all the Securities or portions thereof which have been so accepted for payment
and (iii) not later than 10:00 a.m. (New York time) on the Business Day
following the Change of Control Purchase Date, deliver to the Paying Agent an
Officers' Certificate stating the Securities or portions

                                       - -
<PAGE>
thereof accepted for payment by the Company. The Paying Agent shall promptly
mail or deliver to Holders of Securities so accepted payment in an amount equal
to the Change of Control Purchase Price of the Securities purchased from each
such Holder, and the Company shall execute and the Trustee shall promptly
authenticate and mail or deliver to such Holders a new Security equal in
principal amount to any unpurchased portion of the Security surrendered. Any
Securities not so accepted shall be promptly mailed or delivered by the Paying
Agent at the Company's expense to the Holder thereof. The Company will publicly
announce the results of the Change of Control Offer on the Change of Control
Purchase Date.

                  (e)      A tender made in response to a Change of Control
Purchase Notice may be withdrawn if the Company receives, not later than one
Business Day prior to the Change of Control Purchase Date, a telegram, telex,
facsimile transmission or letter, specifying, as applicable:

                           (1)      the name of the Holder;

                           (2)      the certificate number of the Security in
                  respect of which such notice of withdrawal is being submitted;

                           (3)      the principal amount of the Security (which
                  shall be $1,000 or an integral multiple thereof) delivered for
                  purchase by the Holder as to which such notice of withdrawal
                  is being submitted;

                           (4)      a statement that such Holder is withdrawing
                  his election to have such principal amount of such Security
                  purchased; and

                           (5)      the principal amount, if any, of such
                  Security (which shall be $1,000 or an integral multiple
                  thereof) that remains subject to the original Change of
                  Control Purchase Notice and that has been or will be delivered
                  for purchase by the Company.

                  (f)      The Trustee and the Paying Agent shall return to the
Company any cash that remains unclaimed for two years, together with interest or
dividends, if any, thereon, held by them for the payment of the Change of
Control Purchase Price; provided, however, that, (x) to the extent that the
aggregate amount of cash deposited by the Company pursuant to clause (ii) of
paragraph (d) above exceeds the aggregate Change of Control Purchase Price of
the Securities or portions thereof to be purchased, then the Trustee shall hold
such excess for the Company and (y) unless otherwise directed by the Company in
writing, promptly after the Business Day following the Change of Control
Purchase Date the Trustee shall return any such excess to the Company together
with interest or dividends, if any, thereon.

                  (g)      The Company shall comply, to the extent applicable,
with the applicable tender offer rules, including Rule 14e-1 under the Exchange
Act, and any other applicable securities laws or regulations in connection with
a Change of Control Offer.

                  (h)      Notwithstanding the foregoing, the Company will
not be required to make a Change of Control Offer upon a Change of Control if a
third party makes the Change of Control Offer, in the manner, at the times and
otherwise in compliance with the requirements set

                                       - -

                  (c)      Notwithstanding clauses (a) and (b) above, the
Company's Restricted Subsidiaries may collectively issue, sell or transfer
Preferred Stock, and any Person (other than the Company and its Restricted
Subsidiaries) may acquire Preferred Stock of a Restricted Subsidiary of the
Company, so long as the aggregate Fair Market Value of all Restricted
Subsidiaries issuing such Preferred Stock does not exceed 5% of the Company's
Consolidated Net Tangible Assets.

         Section 1017.     Limitation on Dividend and Other Payment Restrictions
Affecting Subsidiaries.

                  The Company will not, and will not cause or permit any of its
Restricted Subsidiaries to, directly or indirectly, create or otherwise cause to

clause (viii) of the definition of Permitted Indebtedness as to the assets
financed with the proceeds of such Indebtedness; (4) encumbrance or restriction
contained in any Acquired Indebtedness or other agreement of any entity or
related to assets acquired by or merged into or consolidated with the Company or
any Restricted Subsidiaries so long as such encumbrance or restriction was not
entered into in contemplation of the acquisition, merger or consolidation
transaction; (5) encumbrance or restriction existing under applicable law or any
requirement of any regulatory body; (6) Liens securing Indebtedness otherwise
permitted to be incurred under the provisions of Section 1011 herein that limit
the right of the debtor to dispose of the assets subject to such Liens; (7)
restrictions contained in any other indenture or instrument governing debt of
the Company or any Guarantor that are not materially more restrictive, taken as
a whole, than those contained in this Indenture governing the Securities; (8)
restrictions contained in any other credit facility governing debt of the
Company or any Guarantor that are not (in the view of the Board of Directors of
the Company as expressed in a Board Resolution thereof) materially more
restrictive, taken as a whole, than those contained in the Credit Agreement; (9)
encumbrance or restriction with respect to a Securitization Entity in connection
with a Qualified Securitization Transaction; provided, however, that such

sponsor or arranger of such Qualified Securitization Transaction in similar
types of documents relating to the purchase of similar receivables in connection
with the financing thereof; (10) customary restrictions imposed by the terms of
shareholders', partnership or joint venture agreements entered into in the
ordinary course of business; provided, however, that such restrictions do not
apply to any Restricted Subsidiaries other than the applicable company,
partnership or joint venture; and provided, further, however, that such
encumbrances and restrictions may not materially impact the ability of the
Company to permit payments on the Securities when due as required by the terms
of this Indenture; (1 1) restrictions contained in Indebtedness of Foreign
Subsidiaries permitted to be incurred under this Indenture, so long as such
restrictions or encumbrances are customary for Indebtedness of the type issued

that extends, renews, refinances or replaces the agreements containing the
encumbrances or restrictions in the foregoing clauses (1) through (14), or in
this clause (15), provided that the terms and conditions of any such
encumbrances or restrictions are no more restrictive in any material respect
than those under or pursuant to the agreement evidencing the Indebtedness so
extended, renewed, refinanced or replaced.

         Section 1018.     Limitation on Unrestricted Subsidiaries.

         The Company may designate after the Issue Date any Subsidiary as an
"Unrestricted Subsidiary" under this Indenture (a "Designation") only if:

                                       - -
<PAGE>
                  (a)      no Default shall have occurred and be continuing at
         the time of or after giving effect to such Designation;

                  (b)      the Company would be permitted to make an Investment
         (other than a Permitted Investment) at the time of Designation
         (assuming the effectiveness of such Designation) pursuant to paragraph
         (a) of Section 1009 hereof in an amount (the "Designation Amount")
         equal to the greater of (1) the net book value of the Company's
         interest in such Subsidiary calculated in accordance with GAAP or (2)
         the Fair Market Value of the Company's interest in such Subsidiary as
         determined in good faith by the Company's Board of Directors;

                  (c)      the Company would be permitted under this Indenture
         to incur $1.00 of additional Indebtedness (other than Permitted
         Indebtedness) pursuant to Section 1008 hereof at the time of such
         Designation (assuming the effectiveness of such Designation);

                  (d)      such Unrestricted Subsidiary does not own any Capital
         Stock in any Restricted Subsidiary of the Company which is not
         simultaneously being designated an Unrestricted Subsidiary;

                  (e)      such Unrestricted Subsidiary is not liable, directly
         or indirectly, with respect to any Indebtedness other than Unrestricted
         Subsidiary Indebtedness, provided that an Unrestricted Subsidiary may
         provide a Guarantee for the Securities; and

                  (f)      such Unrestricted Subsidiary is not a party to any
         agreement, contract, arrangement or understanding at such time with the
         Company or any Restricted Subsidiary unless the terms of any such
         agreement, contract, arrangement or understanding are no less favorable
         to the Company or such Restricted Subsidiary than those that might be
         obtained at the time from Persons who are not Affiliates of the Company
         or, in the event such condition is not satisfied, the value of such
         agreement, contract, arrangement or understanding to such Unrestricted
         Subsidiary shall be deemed a Restricted Payment.

         In the event of any such Designation, the Company shall be deemed to
have made an Investment constituting a Restricted Payment pursuant to Section
1009 hereof for all purposes of this Indenture in the Designation Amount.

         The Company shall not and shall not cause or permit any Restricted
Subsidiary to at any time (a) provide credit support for, guarantee or subject
any of its property or assets (other than the Capital Stock of any Unrestricted
Subsidiary) to the satisfaction of, any Indebtedness of any Unrestricted
Subsidiary (including any undertaking, agreement or instrument evidencing such
Indebtedness) (other than Permitted Investments in Unrestricted Subsidiaries) or
(b) be directly or indirectly liable for any Indebtedness of any Unrestricted
Subsidiary. For purposes of the foregoing, the Designation of a Subsidiary of
the Company as an Unrestricted Subsidiary shall be deemed to be the Designation
of all of the Subsidiaries of such Subsidiary as Unrestricted Subsidiaries.
Unless so designated as an Unrestricted Subsidiary, any Person that becomes a
Subsidiary of the Company will be classified as a Restricted Subsidiary.

                                       - -

         The Company may revoke any Designation of a Subsidiary as an
Unrestricted Subsidiary (a "Revocation") if:

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

                  (b)      all Liens and Indebtedness of such Unrestricted
         Subsidiary outstanding immediately following such Revocation would, if
         incurred at such time, have been permitted to be incurred for all
         purposes of this Indenture; and

                  (c)      unless such redesignated Subsidiary shall not have
         any Indebtedness outstanding (other than Indebtedness that would be
         Permitted Indebtedness), immediately after giving effect to such
         proposed Revocation, and after giving pro forma effect to the
         incurrence of any such Indebtedness of such redesignated Subsidiary as
         if such Indebtedness was incurred on the date of the Revocation, the
         Company could incur $1.00 of additional Indebtedness (other than
         Permitted Indebtedness) pursuant to Section 1008 herein.

                  All Designations and Revocations must be evidenced by a

certifying compliance with the foregoing provisions.

                  Whether or not the Company is subject to Section 13(a) or
15(d) of the Exchange Act, the Company and any Guarantor will, to the extent
permitted under the Exchange Act, file with the Commission the annual reports,
quarterly reports and other documents which the Company and such Guarantor would
have been required to file with the Commission pursuant to Sections 13(a) or
15(d) if the Company or such Guarantor were so subject, such documents to be

within 15 days of each Required Filing Date (1) transmit by mail to all holders,

quarterly reports and other documents which the Company and such Guarantor would
have been required to file with the Commission pursuant to Sections 13(a) or
15(d) of the Exchange Act if the Company and such Guarantor were subject to
either of such Sections and (b) if filing such documents by the Company and such
Guarantor with the Commission is not permitted under the Exchange Act, promptly
upon written request and payment of the reasonable cost of duplication and
delivery, supply copies of such documents to any prospective holder at the
Company's cost.

                  If any Guarantor's or secured party's financial statements
would be required to be included in the financial statements filed or delivered
pursuant to this Indenture if the Company were subject to Section 13(a) or 15(d)
of the Exchange Act, the Company shall include such Guarantor's financial
statements in any filing or delivery pursuant to this Indenture.

outstanding, the Company will make available to any prospective purchaser of
Securities or beneficial owner of Securities in connection with any sale thereof
the information required by Rule 144A(d)(4) under the Securities Act, until such
time as the Company has either exchanged the Securities for securities identical
in all material respects which have been registered under the Securities Act or
until such time as the holders thereof have disposed of such Securities pursuant
to an effective registration statement under the Securities Act.

                  If a Fall Away Event has occurred, then, subject to Section
1023 herein, the Company will not, and will not permit any Restricted Subsidiary
(other than a Foreign Subsidiary) to, enter into any Sale Leaseback Transaction

of the Company and its Restricted Subsidiaries in respect of the Sale Leaseback
Transaction and all other Sale Leaseback Transactions entered into after the
date of the Fall Away Event and otherwise prohibited by this Indenture, plus the
aggregate principal amount of Indebtedness secured by Liens incurred pursuant to

the purchase of or investment in property or other assets having a Fair Market
Value, determined at the time of such purchase, at least equal to the Net Cash
Proceeds of such sale and which will be used in the business of the Company and
its Restricted Subsidiaries then being conducted.

                  (a)      The Company and the Guarantors will deliver to the
Trustee, on or before a date not more than 120 days after the end of each fiscal

knowledge, based on such review, of the signers thereof, the Company and each
Guarantor have fulfilled all of their respective obligations and are in
compliance with all conditions and covenants under this Indenture throughout
such year or quarter, as the case may be, and, if there has been a Default
specifying each Default and the nature and status thereof and any actions being
taken by the Company and the Guarantors with respect thereto.

                  (b)      When any Default or Event of Default has occurred and
is continuing, or if the Trustee or any Holder or the trustee for or the holder
of any other evidence of Indebtedness of the Company or any Subsidiary gives any
notice or takes any other action with respect to a claimed default, the Company
shall deliver to the Trustee by registered or certified mail or facsimile

specifying such Default, Event of Default, notice or other action, the status
thereof and what

                                       - -

actions the Company and the Guarantors are taking or propose to take with
respect thereto, within five Business Days after the occurrence of such Default

instance to comply with any covenant or condition set forth in Sections 1005
through 1011, 1013, 1014, and 1016 through 1021, if, before or after the time
for such compliance, the Holders of not less than a majority in aggregate
principal amount of the Securities at the time Outstanding shall, by Act of such
Holders, waive such compliance in such instance with such covenant or provision,
but no such waiver shall extend to or affect such covenant or condition except
to the extent so expressly waived, and, until such waiver shall become
effective, the obligations of the Company and the duties of the Trustee in
respect of any such covenant or condition shall remain in full force and effect.

         Section 1101.     Rights of Redemption.

                  (a)      The Securities are subject to redemption at any time
on or after January 15, 2008, at the option of the Company, in whole or in part,
subject to the conditions, and at the Redemption Prices, specified in the form
of Security, together with accrued and unpaid interest, if any, to the
Redemption Date (subject to the right of Holders of record on relevant Regular
Record Dates and Special Record Dates to receive interest due on relevant
Interest Payment Dates and Special Payment Dates).

                  (b)      In addition, at any time prior to January 15, 2006,
the Company, at its option, may use the net proceeds of one or more Public
Equity Offerings to redeem up to an aggregate of 35% of the aggregate principal
amount of Securities issued under this Indenture (including the principal amount
of any Additional Securities issued under this Indenture) at a redemption price
equal to 108.875% of the aggregate principal amount thereof, plus accrued and

                                       - -
<PAGE>
unpaid interest thereon, if any, to the Redemption Date; provided that at least
65% of the aggregate principal amount of Securities (including the principal
amount of any Additional Securities issued under this Indenture) remains
outstanding immediately after the occurrence of such redemption. In order to
effect the foregoing redemption, the Company must mail a notice of redemption no
later than 30 days after the closing of the related Public Equity Offering and
must consummate such redemption within 60 days of the closing of the Public
Equity Offering.

         Section 1102.     Applicability of Article.

                  Redemption of Securities at the election of the Company or
otherwise, as permitted or required by any provision of this Indenture, shall be
made in accordance with such provision and this Article Eleven.

         Section 1103.     Election to Redeem; Notice to Trustee.

                  The election of the Company to redeem any Securities pursuant
to Section 1101 shall be evidenced by a Company Order and an Officers'
Certificate. In case of any redemption at the election of the Company, the
Company shall, not less than 45 nor more than 60 days prior to the Redemption
Date fixed by the Company (unless a shorter notice period shall be satisfactory
to the Trustee), notify the Trustee in writing of such Redemption Date and of
the principal amount of Securities to be redeemed.

         Section 1104.     Selection by Trustee of Securities to Be Redeemed.

                  If less than all the Securities are to be redeemed, the
particular Securities or portions thereof to be redeemed shall be selected not
more than 30 days prior to the Redemption Date. The Trustee shall select the
Securities or portions thereof to be redeemed in compliance with the
requirements of the principal national security exchange, if any, on which the
Securities are listed, or if the Securities are not so listed, pro rutu, by lot
or by any other method the Trustee shall deem fair and reasonable. The amounts
to be redeemed shall be equal to $1,000 or any integral multiple thereof.
Redemption pursuant to the provisions of Section 1101(b) relating to a Public
Equity Offering must be made on a pro rata basis or on as nearly a pro rata
basis as practicable (subject to the procedures of DTC or any other depositary).

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

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

         Section 1105.     Notice of Redemption.

                  Notice of redemption shall be given by first-class mail,
postage prepaid, mailed not less than 30 days nor more than 60 days prior to the
Redemption Date, to each Holder of Securities to be redeemed, at its address
appearing in the Security Register.

                                       - -

                  All notices of redemption shall state:

                  (a)      the Redemption Date;

                  (b)      the Redemption Price;

                  (c)      if less than all Outstanding Securities are to be
redeemed, the identification of the particular Securities to be redeemed;

                  (d)      in the case of a Security to be redeemed in part, the
principal amount of such Security to be redeemed and that after the Redemption
Date upon surrender of such Security, new Security or Securities in the
aggregate principal amount equal to the unredeemed portion thereof will be
issued;

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

                  (f)      that on the Redemption Date the Redemption Price will
become due and payable upon each such Security or portion thereof to be
redeemed, and that (unless the Company shall default in payment of the
Redemption Price) interest thereon shall cease to accrue on and after said date;

                  (g)      the names and addresses of the Paying Agent and the
offices or agencies referred to in Section 1002 where such Securities are to be
surrendered for payment of the Redemption Price;

                  (h)      the CUSIP number, if any, relating to such
Securities; and

                  (i)      the procedures that a Holder must follow to surrender
the Securities to be redeemed.

                  Notice of redemption of Securities to be redeemed at the
election of the Company shall be given by the Company or, at the Company's
written request and upon at least five (5) days notice to the Trustee, by the
Trustee in the name and at the expense of the Company. If the Company elects to
give notice of redemption, it shall provide the Trustee with a certificate
stating that such notice has been given in compliance with the requirements of
this Section 1105.

                  The notice if mailed in the manner herein provided shall be
conclusively presumed to have been given, whether or not the Holder receives
such notice. In any case, failure to give such notice by mail or any defect in
the notice to the Holder of any Security designated for redemption as a whole or
in part shall not affect the validity of the proceedings for the redemption of
any other Security.

         Section 1106.     Deposit of Redemption Price.

                  On or prior to any Redemption Date, the Company shall deposit
with the Trustee or with a Paying Agent (or, if the Company or any of its
Affiliates is acting as Paying Agent, segregate and hold in trust as provided in
Section 1003) an amount of money in same day funds

                                       - -
<PAGE>
sufficient to pay the Redemption Price of, and (except if the Redemption Date
shall be an Interest Payment Date or Special Payment Date) accrued interest on,
all the Securities or portions thereof which are to be redeemed on that date.
The Paying Agent shall promptly mail or deliver to Holders of Securities so
redeemed payment in an amount equal to the Redemption Price of the Securities
purchased from each such Holder. All money, if any, earned on funds held in
trust by the Trustee or any Paying Agent shall be remitted to the Company. For
purposes of this Section 1106, the Company shall choose a Paying Agent which
shall not be the Company.

         Section 1107.     Securities Payable on Redemption Date.

                  Notice of redemption having been given as aforesaid, the
Securities so to be redeemed shall, on the Redemption Date, become due and
payable at the Redemption Price therein specified and from and after such date
(unless the Company shall default in the payment of the Redemption Price and
accrued interest) such Securities shall cease to bear interest. Upon surrender
of any such Security for redemption in accordance with said notice, such
Security shall be paid by the Company at the Redemption Price together with
accrued interest to the Redemption Date; provided, however, that installments of
interest whose Stated Maturity is on or prior to the Redemption Date shall be
payable to the Holders of such Securities, or one or more Predecessor
Securities, registered as such on the relevant Regular Record Dates and Special
Record Dates according to the terms and the provisions of Section 309.

                  If any Security called for redemption shall not be so paid
upon surrender thereof for redemption, the principal and premium, if any, shall,
until paid, bear interest from the Redemption Date at the rate borne by such
Security.

         Section 1108.     Securities Redeemed or Purchased in Part.

                  Any Security which is to be redeemed or purchased only in part
shall be surrendered to the Paying Agent at the office or agency maintained for
such purpose pursuant to Section 1002 (with, if the Company, the Security
Registrar or the Trustee so requires, due endorsement by, or a written
instrument of transfer in form satisfactory to the Company, the Security
Registrar or the Trustee, as the case may be, duly executed by, the Holder
thereof or such Holder's attorney duly authorized in writing), and the Company
shall execute, and the Trustee shall authenticate and deliver to the Holder of
such Security without service charge, a new Security or Securities, of any
authorized denomination as requested by such Holder in aggregate principal
amount equal to, and in exchange for, the unredeemed portion of the principal of
the Security so surrendered that is not redeemed or purchased.

further effect (except as to surviving rights of registration of transfer or
exchange of Securities as expressly provided for herein) as to all Outstanding
Securities hereunder, and the Trustee, upon Company Request and

                                       - -
<PAGE>
at the expense of the Company, shall execute proper instruments acknowledging
satisfaction and discharge of this Indenture, when

                  (a)      either

                           (1)      all such Securities theretofore
                  authenticated and delivered (other than (i) lost, stolen or
                  destroyed Securities which have been replaced or paid as
                  provided in Section 308 or (ii) all Securities for whose
                  payment money has theretofore been deposited in trust or
                  segregated and held in trust by the Company and thereafter
                  repaid to the Company or discharged from such trust as
                  provided in Section 1003) have been delivered to the Trustee
                  for cancellation; or

                           (2)      all Securities not theretofore delivered to
                  the Trustee for cancellation (i) have become due and payable,

                  within one year, or (iii) are to be called for redemption
                  within one year under arrangements satisfactory to the Trustee
                  for the giving of notice of redemption by the Trustee in the
                  name, and at the expense, of the Company;

                  (b)      the Company or any Guarantor has irrevocably
         deposited or caused to be deposited with the Trustee as trust funds in
         trust an amount in United States dollars sufficient to pay and
         discharge the entire Indebtedness on the Securities not theretofore
         delivered to the Trustee for cancellation, including the principal of,
         premium, if any, and accrued interest on, such Securities at such
         Maturity, Stated Maturity or Redemption Date;

                  (c)      no Default or Event of Default shall have occurred
and be continuing on the date of such deposit;

                  (d)      the Company or any Guarantor has paid or caused to be
paid all other sums payable hereunder by the Company and any Guarantor; and

                  (e)      the Company has delivered to the Trustee an Officers'
Certificate and an Opinion of Independent Counsel, in form and substance
satisfactory to the Trustee, each stating that all conditions precedent herein
relating to the satisfaction and discharge hereof have been complied with.

                  Notwithstanding the satisfaction and discharge hereof, the
obligations of the Company to the Trustee under Section 607 and, if United
States dollars shall have been deposited with the Trustee pursuant to subclause
(2) of subsection (a) of this Section 1201, the obligations of the Trustee under
Section 1202 and the last paragraph of Section 1003 shall survive.

         Section 1202.     Application of Trust Money.

                  Subject to the provisions of the last paragraph of Section
1003, all United States dollars deposited with the Trustee pursuant to Section

Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of
the principal of, premium, if any, and interest on, the Securities for whose
payment such United States dollars have been deposited with the Trustee.

that, to the extent and in the manner hereinafter set forth in this Article, the
Indebtedness represented by the Securities and the payment of the principal of,

subordinate and subject in right of payment as provided in this Article to the
prior payment in full in cash (or in any other form as acceptable to the holders
of Senior Indebtedness) of the Senior Indebtedness.

                  This Article Thirteen shall constitute a continuing offer to
all Persons who, in reliance upon such provisions, become holders of, or
continue to hold Senior Indebtedness; and such provisions are made for the
benefit of the holders of Senior Indebtedness; and such holders are made
obligees hereunder and they or each of them may enforce such provisions as
provided herein.

case or proceeding, relative to the Company or to its assets, or (b) any
liquidation, dissolution or other winding up of the Company, whether voluntary
or involuntary, or (c) any assignment for the benefit of creditors or any other
marshaling of assets or liabilities of the Company, then and in any such event:

                  (1)      the holders of Senior Indebtedness shall be entitled
to receive payment in full in cash (or in any other form as acceptable to the
holders of Senior Indebtedness) of all amounts due on or in respect of Senior
Indebtedness before the Holders of the Securities are entitled to receive any
payment or distribution of any kind or character (other than any payment or
distribution in the form of Permitted Junior Securities and any amounts
previously set aside with the Trustee or payments previously made, in either
case, pursuant to the provisions described under Article Four hereof) on account
of the principal of, premium, if any, or interest on the Securities or on
account of the purchase, redemption, defeasance or other acquisition of, or in
respect of, the Securities; and

                  (2)      any payment or distribution of assets of the Company
of any kind or character, whether in cash, property or securities (excluding
Permitted Junior Securities), by set- off or otherwise, to which the Holders or
the Trustee would be entitled but for the provisions of this Article shall be
paid by the liquidating trustee or agent or other Person making such payment or
distribution, whether a trustee in bankruptcy, a receiver or liquidating trustee
or otherwise,

                                       - -
<PAGE>

representatives or to the trustee or trustees under any indenture under which
any instruments evidencing any of such Senior Indebtedness may have been issued,
ratably according to the aggregate amounts remaining unpaid on account of the
Senior Indebtedness held or represented by each, to the extent necessary to make
payment in full in cash (or in any other form as acceptable to the holders of
Senior Indebtedness) of all Senior Indebtedness remaining unpaid, after giving
effect to any concurrent payment or distribution to the holders of such Senior
Indebtedness; and

                  (3)      in the event that, notwithstanding the foregoing
provisions of this Section, the Trustee or the Holder of any Security shall have
received any payment or distribution of assets of the Company of any kind or
character, whether in cash, property or securities (excluding Permitted Junior
Securities), in respect of principal, premium, if any, and interest on the
Securities before all Senior Indebtedness is paid in full in cash (or in any
other form as acceptable to the holders of Senior Indebtedness), then and in
such event such payment or distribution (excluding Permitted Junior Securities)
shall be paid over or delivered forthwith to the trustee in bankruptcy,
receiver, liquidating trustee, custodian, assignee, agent or other Person making
payments or distributions of assets of the Company for application to the
payment of all Senior Indebtedness remaining unpaid, to the extent necessary to

Company with or into, another Person or the liquidation or dissolution of the
Company following the sale, assignment, conveyance, transfer, lease or other
disposal of its properties and assets substantially as an entirety to another
Person upon the terms and conditions set forth in Article Eight shall not be
deemed a dissolution, winding up, liquidation, reorganization, assignment for
the benefit of creditors or marshaling of assets and liabilities of the Company
for the purposes of this Section if the Person formed by such consolidation or
the surviving entity of such merger or the Person which acquires by sale,
assignment, conveyance, transfer, lease or other disposal of such properties and
assets substantially as an entirety, as the case may be, shall, as a part of
such consolidation, merger, sale, assignment, conveyance, transfer, lease or
other disposal, comply with the conditions set forth in Article Eight.

         Section 1303.     Suspension of Payment When Designated Senior
Indebtedness in Default.

                  (a)      Unless Section 1302 shall be applicable, upon the
occurrence of any default in the payment of any Designated Senior Indebtedness
beyond any applicable grace period (a "Payment Default") and after the receipt
by the Trustee from a Senior Representative of any Designated Senior
Indebtedness of written notice of such default, no payment (other than any
payment or distribution in the form of Permitted Junior Securities and any
payment previously set aside with the Trustee or payments previously made, in
either case, pursuant to Section 402 or 403 in this Indenture) or distribution
of any assets of the Company of any kind or character may be made on account of
the principal of, premium, if any, or interest on, the Securities, or on account
of the purchase, redemption, defeasance or other acquisition of or in respect
of, the Securities unless and until such Payment Default shall have been cured
or waived or shall have ceased to exist or such Designated Senior Indebtedness
shall have been discharged

                                       - -
<PAGE>
or paid in full in cash (or in any other form as acceptable to the holders of
Senior Indebtedness), after which the Company shall (subject to the other
provisions of this Article Thirteen) resume making any and all required payments
in respect of the Securities, including any missed payments.

                  (b)      Unless Section 1302 shall be applicable, (1) upon the
occurrence and during the continuance of any non-payment default with respect to
any Designated Senior Indebtedness pursuant to which the maturity thereof may
then be accelerated immediately (a "Non-payment Default") and (2) after the
receipt by the Trustee and the Company from a Senior Representative of any
Designated Senior Indebtedness of written notice of such Non-payment Default, no
payment (other than any payment or distribution in the form of Permitted Junior
Securities and any payment previously set aside with the Trustee, or payments
previously made, in either case, pursuant to the provisions of Sections 402 or
403 in this Indenture) or distribution of any assets of the Company of any kind
or character may be made by the Company on account of the principal of, premium,
if any, or interest on, the Securities, or on account of the purchase,
redemption, defeasance or other acquisition of, or in respect of, the Securities
for the period specified below ("Payment Blockage Period").

                  (c)      The Payment Blockage Period shall commence upon the
receipt of notice of the Non-payment Default by the Trustee and the Company from
a Senior Representative and shall end on the earliest of (i) the 179th day after
such commencement, (ii) the date on which such Non-payment Default (and all
Non-payment Defaults as to which notice is given after such Payment Blockage
Period is initiated) is cured, waived or ceases to exist or on which such
Designated Senior Indebtedness is discharged or paid in full in cash (or in any
other form as acceptable to the holders of Senior Indebtedness), or (iii) the
date on which such Payment Blockage Period (and all other Non-payment Defaults
as to which notice is given after such Payment Blockage Period is initiated)
shall have been terminated by written notice to the Company or the Trustee from
the Senior Representative initiating such Payment Blockage Period. When the
Payment Blockage Period ends, unless a Payment Default has occurred and is
continuing, the Company shall promptly resume making any and all required
payments in respect of the Securities, including any missed payments. In no
event will a Payment Blockage Period extend beyond 179 days from the date of the
receipt by the Company or the Trustee of the notice initiating such Payment
Blockage Period (such 179-day period referred to as the "Initial Period"). Any
number of notices of Non-payment Defaults may be given during the Initial
Period. However, during any period of 365 consecutive days only one Payment
Blockage Period may commence, the duration of such period may not exceed 179
days, and there must be a 186 consecutive day period in any 365 day period
during which no Payment Blockage Period is in effect. No Non-payment Default
with respect to Designated Senior Indebtedness that existed or was continuing on
the date of the commencement of any Payment Blockage Period will be, or can be,
made the basis for the commencement of a second Payment Blockage Period, whether
or not within a period of 365 consecutive days, unless such default has been
cured or waived for a period of not less than 90 consecutive days subsequent to
the commencement of the Initial Period (it being acknowledged that any
subsequent action or any breach of a financial covenant for a period ending
after the date of commencement of such Payment Blockage Period that, in either
case, would give rise to an event of default pursuant to any provision under
which an Event of Default previously existed or was continuing shall constitute
a new Event of Default for this purpose). The Company shall deliver a notice to
the Trustee promptly after the date on

which any Non-payment Default is cured or waived or ceases to exist or on which
the Designated Senior Indebtedness related thereto is discharged or paid in full
in cash (or in any other form as acceptable to the holders of Senior
Indebtedness), and the Trustee is authorized to act in reliance on such notice.

         Section 1304.     Payment Permitted if No Default.

                  Nothing contained in this Article, elsewhere in this Indenture
or in any of the Securities shall prevent the Company, at any time except during
the pendency of any case, proceeding, dissolution, liquidation or other
winding-up, assignment for the benefit of creditors or other marshaling of
assets and liabilities of the Company referred to in Section 1302 or under the
conditions described in Section 1303, from making payments at any time of
principal of, premium, if any, or interest on the Securities.

         Section 1305.     Subrogation to Rights of Holders of Senior
Indebtedness.

                  After the payment in full in cash (or in any other form as
acceptable to the holders of Senior Indebtedness) of all Senior Indebtedness,
the Holders of the Securities shall be subrogated to the rights of the holders
of such Senior Indebtedness to receive payments and distributions of cash,
property and securities applicable to the Senior Indebtedness until the
principal of, premium, if any, and interest on, the Securities shall be paid in
full. For purposes of such subrogation, no payments or distributions to the
holders of Senior Indebtedness of any cash, property or securities to which the
Holders of the Securities or the Trustee would be entitled except for the
provisions of this Article, and no payments over pursuant to the provisions of
this Article to the holders of Senior Indebtedness by Holders of the Securities
or the Trustee, shall, as among the Company, its creditors other than holders of
Senior Indebtedness, and the Holders of the Securities, be deemed to be a
payment or distribution by the Company to or on account of the Senior
Indebtedness.

         Section 1306.     Provisions Solely to Define Relative Rights.

                  The provisions of this Article are intended solely for the
purpose of defining the relative rights of the Holders of the Securities on the
one hand and the holders of Senior Indebtedness on the other hand. Nothing
contained in this Article or elsewhere in this Indenture or in the Securities is
intended to or shall (a) impair, as among the Company, its creditors other than
holders of Senior Indebtedness and the Holders of the Securities, the obligation
of the Company, which is absolute and unconditional, to pay to the Holders of
the Securities the principal of, premium, if any, and interest on, the
Securities as and when the same shall become due and payable in accordance with
their terms; or (b) affect the relative rights against the Company or the
Holders of the Securities and creditors of the Company other than the holders of
Senior Indebtedness; or (c) prevent the Trustee or the Holder of any Security
from exercising all remedies otherwise permitted by applicable law upon default
under this Indenture, subject to the rights, if any, under this Article of the
holders of Senior Indebtedness (1) in any case, proceeding, dissolution,
liquidation or other winding up, assignment for the benefit of creditors or
other marshaling of assets and liabilities of the Company referred to in Section
1302, to receive, pursuant to and in accordance with such Section, cash,
property and securities otherwise

                                       - -
<PAGE>
payable or deliverable to the Trustee or such Holder, or (2) under the
conditions specified in Section 1303, to prevent any payment prohibited by such
Section.

         Section 1307.     Trustee to Effectuate Subordination.

                  Each Holder of a Security by such Holder's acceptance thereof
authorizes and directs the Trustee on such Holder's behalf to take such action
as may be necessary or appropriate to effectuate the subordination provided in
this Article and appoints the Trustee such Holder's attorney-in-fact for any and
all such purposes, including, in the event of any dissolution, winding-up,
liquidation or reorganization of the Company whether in bankruptcy, insolvency,
receivership proceedings, or otherwise, the timely filing of a claim for the
unpaid balance of the indebtedness of the Company owing to such Holder in the
form required in such proceedings and the causing of such claim to be approved.

         Section 1308.     No Waiver of Subordination Provisions.

                  (a)      No right of any present or future holder of any
Senior Indebtedness to enforce subordination as herein provided shall at any
time in any way be prejudiced or impaired by any act or failure to act on the
part of the Company or by any act or failure to act, in good faith, by any such
holder, or by any non-compliance by the Company with the terms, provisions and
covenants of this Indenture, regardless of any knowledge thereof any such holder
may have or be otherwise charged with.

                  (b)      Without limiting the generality of subsection (a) of
this Section, the holders of Senior Indebtedness may, at any time and from time
to time, without the consent of or notice to the Trustee or the Holders of the
Securities, without incurring responsibility to the Holders of the Securities
and without impairing or releasing the subordination provided in this Article or
the obligations hereunder of the Holders of the Securities to the holders of
Senior Indebtedness, do any one or more of the following: (1) change the manner,
place or terms of payment or extend the time of payment of, or renew or alter,
Senior Indebtedness or any instrument evidencing the same or any agreement under
which Senior Indebtedness is outstanding; (2) sell, exchange, release or
otherwise deal with any property pledged, mortgaged or otherwise securing Senior
Indebtedness; (3) release any Person liable in any manner for the collection or
payment of Senior Indebtedness; and (4) exercise or refrain from exercising any
rights against the Company and any other Person; provided, however, that in no
event shall any such actions limit the right of the Holders of the Securities to
take any action to accelerate the maturity of the Securities pursuant to
Article Five of this Indenture or to pursue any rights or remedies hereunder or
under applicable laws if the taking of such action does not otherwise violate
the terms of this Article.

         Section 1309.     Notice to Trustee.

                  (a)      The Company shall give prompt written notice to the
Trustee of any fact known to the Company which would prohibit the making of any
payment to or by the Trustee in respect of the Securities. Notwithstanding the
provisions of this Article or any other provision of this Indenture, the Trustee
shall not be charged with knowledge of the existence of any facts which would
prohibit the making of any payment to or by the Trustee in respect of the
Securities,

                                       - -
<PAGE>
unless and until the Trustee shall have received written notice thereof from the
Company or a holder of Senior Indebtedness or from a Senior Representative or
any trustee, fiduciary or agent therefor; and, prior to the receipt of any such
written notice, the Trustee shall be entitled in all respects to assume that no
such facts exist; provided, however, that if the Trustee shall not have received
the notice provided for in this Section by Noon, Eastern Time, on the Business
Day prior to the date upon which by the terms hereof any money may become
payable for any purpose (including, without limitation, the payment of the
principal of, premium, if any, or interest on any Security), then, anything
herein contained to the contrary notwithstanding but without limiting the rights
and remedies of the holders of Senior Indebtedness, a Senior Representative or
any trustee, fiduciary or agent thereof, the Trustee shall have full power and
authority to receive such money and to apply the same to the purpose for which
such money was received and shall not be affected by any notice to the contrary
which may be received by it after such date; nor shall the Trustee be charged
with knowledge of the curing of any such default or the elimination of the act
or condition preventing any such payment unless and until the Trustee shall have
received an Officers' Certificate to such effect.

                  (b)      The Trustee shall be entitled to rely on the delivery
to it of a written notice to the Trustee and the Company by a Person which
represents itself as a Senior Representative or a holder of Senior Indebtedness
(or a trustee, fiduciary or agent therefor) to establish that such notice has
been given by a Senior Representative or a holder of Senior Indebtedness (or a
trustee, fiduciary or agent therefor); provided, however, that failure to give
such notice to the Company shall not affect in any way the ability of the
Trustee to rely on such notice. In the event that the Trustee determines in good
faith that further evidence is required with respect to the right of any Person
as a holder of Senior Indebtedness to participate in any payment or distribution
pursuant to this Article, the Trustee may request such Person to furnish
evidence to the reasonable satisfaction of the Trustee as to the amount of
Senior Indebtedness held by such Person, the extent to which such Person is
entitled to participate in such payment or distribution and any other facts
pertinent to the rights of such Person under this Article, and if such evidence
is not furnished, the Trustee may defer any payment to such Person pending
judicial determination as to the right of such Person to receive such payment.

         Section 1310.     Reliance on Judicial Orders or Certificates.

                  Upon any payment or distribution of assets of the Company
referred to in this Article, the Trustee and the Holders of the Securities shall
be entitled to rely upon any order or decree entered by any court of competent
jurisdiction in which such insolvency, bankruptcy, receivership, liquidation,
reorganization, dissolution, winding up or similar case or proceeding is
pending, or a certificate of the trustee in bankruptcy, receiver, liquidating
trustee, custodian, assignee for the benefit of creditors, agent or other person
making such payment or distribution, or a certificate of a Senior
Representative, delivered to the Trustee or to the Holders of Securities for the
purpose of ascertaining the Persons entitled to participate in such payment or
distribution, the holders of Senior Indebtedness and other indebtedness of the
Company, the amount thereof or payable thereon, the amount or amounts paid or
distributed thereon and all other facts pertinent thereto or to this Article,
provided that the foregoing shall apply only if such court has been fully
apprised of the provisions of this Article.

         Section 1311.     Rights of Trustee as a Holder of Senior Indebtedness;
Preservation of Trustee's Rights.

                  The Trustee in its individual capacity shall be entitled to
all the rights set forth in this Article with respect to any Senior Indebtedness
which may at any time be held by it, to the same extent as any other holder of
Senior Indebtedness, and nothing in this Indenture shall deprive the Trustee of
any of its rights as such holder. Nothing in this Article shall apply to claims
of, or payments to, the Trustee under or pursuant to Section 607.

         Section 1312.     Article Applicable to Paying Agents.

                  In case at any time any Paying Agent other than the Trustee
shall have been appointed by the Company and be then acting under this
Indenture, the term "Trustee" as used in this Article shall in such case (unless
the context otherwise requires) be construed as extending to and including such
Paying Agent within its meaning as fully for all intents and purposes as if such
Paying Agent were named in this Article in addition to or in place of the
Trustee; provided, however, that Section 1311 shall not apply to the Company or
any Affiliate of the Company if it or such Affiliate acts as Paying Agent.

         Section 1313.     No Suspension of Remedies.

                  Nothing contained in this Article shall limit the right of the
Trustee or the Holders of Securities to take any action to accelerate the
maturity of the Securities pursuant to Article Five of this Indenture or to
pursue any rights or remedies hereunder or under applicable law, subject to the
rights, if any, under this Article of the holders, from time to time, of Senior
Indebtedness to receive the cash, property or securities receivable upon the
exercise of such rights or remedies.

         Section 1314.     Trustee's Relation to Senior Indebtedness.

                  With respect to the holders of Senior Indebtedness, the
Trustee undertakes to perform or to observe only such of its covenants and
obligations as are specifically set forth in this Article, and no implied
covenants or obligations with respect to the holders of Senior Indebtedness
shall be read into this Article against the Trustee. The Trustee shall not be
deemed to owe any fiduciary duty to the holders of Senior Indebtedness and the
Trustee shall not be liable to any holder of Senior Indebtedness if it shall in
good faith mistakenly (absent willful misconduct) pay over or deliver to
Holders, the Company or any other Person moneys or assets to which any holder of
Senior Indebtedness shall be entitled by virtue of this Article or otherwise.

                                ARTICLE FOURTEEN

                                   GUARANTEES

         Section 1401.     Guarantors' Guarantee.

                  For value received, each of the Guarantors, in accordance with
this Article Fourteen, hereby absolutely, fully, unconditionally and irrevocably
guarantees, jointly and

                                       - -

severally with each other and with each other Person which may become a
Guarantor hereunder, to the Trustee and the Holders, as if the Guarantors were
the principal debtor, the punctual payment and performance when due of all
Indenture Obligations (which for purposes of this Guarantee shall also be deemed
to include all commissions, fees, charges, costs and other expenses (including
reasonable legal fees and disbursements of one counsel) arising out of or
incurred by the Trustee or the Holders in connection with the enforcement of
this Guarantee).

         Section 1402.     Continuing Guarantee; No Right of Set-Off;
Independent Obligation.

                  (a)      This Guarantee shall be a continuing guarantee of the
payment and performance of all Indenture Obligations and shall remain in full
force and effect until the payment in full of all of the Indenture Obligations
and shall apply to and secure any ultimate balance due or remaining unpaid to
the Trustee or the Holders; and this Guarantee shall not be considered as wholly
or partially satisfied by the payment or liquidation at any time or from time to
time of any sum of money for the time being due or remaining unpaid to the
Trustee or the Holders. Each Guarantor, jointly and severally, covenants and
agrees to comply with all obligations, covenants, agreements and provisions
applicable to it in this Indenture including those set forth in Article Eight.
Without limiting the generality of the foregoing, each Guarantor's liability
shall extend to all amounts which constitute part of the Indenture Obligations
and would be owed by the Company under this Indenture and the Securities but for
the fact that they are unenforceable, reduced, limited, impaired, suspended or
not allowable due to the existence of a bankruptcy, reorganization or similar
proceeding involving the Company.

                  (b)      Each Guarantor, jointly and severally, hereby
guarantees that the Indenture Obligations will be paid to the Trustee without
set-off or counterclaim or other reduction whatsoever (whether for taxes,
withholding or otherwise) in lawful currency of the United States of America.

                  (c)      Each Guarantor's liability to pay or perform or cause
the performance of the Indenture Obligations under this Guarantee shall arise
forthwith after demand for payment or performance by the Trustee has been given
to the Guarantors in the manner prescribed in Section 106 hereof.

                  (d)      Except as provided herein, the provisions of this
Article Fourteen cover all agreements between the parties hereto relative to
this Guarantee and none of the parties shall be bound by any representation,
warranty or promise made by any Person relative thereto which is not embodied
herein; and it is specifically acknowledged and agreed that this Guarantee has
been delivered by each Guarantor free of any conditions whatsoever and that no
representations, warranties or promises have been made to any Guarantor
affecting its liabilities hereunder, and that the Trustee shall not be bound by
any representations, warranties or promises now or at any time hereafter made by
the Company to any Guarantor.

                  (e)      This Guarantee is a guarantee of payment, performance
and compliance and not of collectibility and is in no way conditioned or
contingent upon any attempt to collect from or enforce performance or compliance
by the Company or upon any event or condition whatsoever.

                  (f)      The obligations of the Guarantors set forth herein
constitute the full recourse obligations of the Guarantors enforceable against
them to the full extent of all their assets and properties.

         Section 1403.     Guarantee Absolute.

                  The obligations of the Guarantors hereunder are independent of
the obligations of the Company under the Securities and this Indenture and a
separate action or actions may be brought and prosecuted against any Guarantor
whether or not an action or proceeding is brought against the Company and
whether or not the Company is joined in any such action or proceeding. The
liability of the Guarantors hereunder is irrevocable, absolute and unconditional
and (to the extent permitted by law) the liability and obligations of the
Guarantors hereunder shall not be released, discharged, mitigated, waived,
impaired or affected in whole or in part by:

                  (a)      any defect or lack of validity or enforceability in
                           respect of any Indebtedness or other obligation of
                           the Company or any other Person under this Indenture
                           or the Securities, or any agreement or instrument
                           relating to any of the foregoing;

                  (b)      any grants of time, renewals, extensions,
                           indulgences, releases, discharges or modifications
                           which the Trustee or the Holders may extend to, or
                           make with, the Company, any Guarantor or any other
                           Person, or any change in the time, manner or place of
                           payment of, or in any other term of, all or any of
                           the Indenture Obligations, or any other amendment or
                           waiver of, or any consent to or departure from, this
                           Indenture or the Securities, including any increase
                           or decrease in the Indenture Obligations;

                  (c)      the taking of security from the Company, any
                           Guarantor or any other Person, and the release,
                           discharge or alteration of, or other dealing with,
                           such security;

                  (d)      the occurrence of any change in the laws, rules,
                           regulations or ordinances of any jurisdiction by any
                           present or future action of any governmental
                           authority or court amending, varying, reducing or
                           otherwise affecting, or purporting to amend, vary,

                           Obligations and the obligations of any Guarantor
                           hereunder;

                  (e)      the abstention from taking security from the Company,

                           enforceability of any security received from the
                           Company, any Guarantor or any other Person, and

                  (q)      any limitation on the liability or obligations of the
                           Company or any other Person under this Indenture, or
                           any discharge, termination, cancellation,
                           distribution, irregularity, invalidity or
                           unenforceability in whole or in part of this
                           Indenture;

                  (r)      any other circumstance that might otherwise
                           constitute a defense available to, or discharge of,
                           the Company or any Guarantor; or

                  (s)      any modification, compromise, settlement or release
                           by the Trustee, or by operation of law or otherwise,
                           of the Indenture Obligations or the liability of the
                           Company or any other obligor under the Securities, in
                           whole or in part, and any refusal of payment by the
                           Trustee, in whole or in part, from any other obligor
                           or other guarantor in connection with any of the
                           Indenture Obligations, whether or not with notice to,
                           or further assent by, or any reservation of rights
                           against, each of the Guarantors.

         Section 1404.     Right to Demand Full Performance.

                  In the event of any demand for payment or performance by the
Trustee from any Guarantor hereunder, the Trustee shall have the right to demand
its full claim and to receive all payments in respect thereof until the
Indenture Obligations have been paid in full, and the Guarantors shall continue
to be jointly and severally liable hereunder for any balance which may be owing
to the Trustee or the Holders by the Company under this Indenture and the
Securities. The retention by the Trustee or the Holders of any security, prior
to the realization by the Trustee or the Holders of its rights to such security
upon foreclosure thereon, shall not, as between the Trustee and any Guarantor,
be considered as a purchase of such security, or as payment, satisfaction or
reduction of the Indenture Obligations due to the Trustee or the Holders by the
Company or any part thereof. Each Guarantor, promptly after demand, will
reimburse the Trustee and the Holders for all costs and expenses of collecting
such amount under, or enforcing this Guarantee, including, without limitation,
the reasonable fees and expenses of counsel.

         Section 1405.     Waivers.

                  (a)      Each Guarantor hereby expressly waives (to the extent
permitted by law) notice of the acceptance of this Guarantee and notice of the
existence, renewal, extension or the non-performance, non-payment, or
non-observance on the part of the Company of any of the terms, covenants,
conditions and provisions of this Indenture or the Securities or any other
notice whatsoever to or upon the Company or such Guarantor with respect to the
Indenture Obligations, whether by statute, rule of law or otherwise. Each
Guarantor hereby acknowledges communication to it of the terms of this Indenture
and the Securities and all of the provisions therein contained and consents to
and approves the same. Each Guarantor hereby expressly waives (to the extent
permitted by law) diligence, presentment, protest and demand for payment with
respect to (i) any notice of sale, transfer or other disposition of any right,
title to or interest in the Securities by the Holders or in this Indenture, (ii)
any release of any Guarantor from its obligations hereunder resulting from any
loss by it of its rights of subrogation hereunder and (iii) any other
circumstances whatsoever that might otherwise constitute a legal or equitable

                                       - -

discharge, release or defense of a guarantor or surety or that might otherwise
limit recourse against such Guarantor.

                  (b)      Without prejudice to any of the rights or recourses
which the Trustee or the Holders may have against the Company, each Guarantor
hereby expressly waives (to the extent permitted by law) any right to require
the Trustee or the Holders to:

                           (i)      enforce, assert, exercise, initiate or
                                    exhaust any rights, remedies or recourse
                                    against the Company, any Guarantor or any
                                    other Person under this Indenture or
                                    otherwise;

                           (ii)     value, realize upon, or dispose of any
                                    security of the Company or any other Person
                                    held by the Trustee or the Holders;

                           (iii)    initiate or exhaust any other remedy which
                                    the Trustee or the Holders may have in law
                                    or equity; or

                           (iv)     mitigate the damages resulting from any
                                    default under this Indenture;

before requiring or becoming entitled to demand payment from such Guarantor
under this Guarantee.

         Section 1406.     The Guarantors Remain Obligated in Event the Company
Is No Longer Obligated to Discharge Indenture Obligations.

                  It is the express intention of the Trustee and the Guarantors
that if for any reason the Company has no legal existence, is or becomes under
no legal obligation to discharge the Indenture Obligations owing to the Trustee
or the Holders by the Company or if any of the Indenture Obligations owing by
the Company to the Trustee or the Holders becomes irrecoverable from the Company
by operation of law or for any reason whatsoever, this Guarantee and the
covenants, agreements and obligations of the Guarantors contained in this
Article Fourteen shall nevertheless be binding upon the Guarantors, as principal
debtor, until such time as all such Indenture Obligations have been paid in full
to the Trustee and all Indenture Obligations owing to the Trustee or the Holders
by the Company have been discharged, or such earlier time as Section 402 shall
apply to the Securities and the Guarantors shall be responsible for the payment
thereof to the Trustee or the Holders upon demand.

         Section 1407.     Fraudulent Conveyance; Contribution; Subrogation.

                  (a)      Each Guarantor that is a Subsidiary of the Company
and, by its acceptance hereof, each Holder hereby confirm that it is the
intention of all such parties that the Guarantee by such Guarantor pursuant to
its Guarantee not constitute a fraudulent transfer or conveyance for purposes of
the Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform
Fraudulent Transfer Act or any similar federal or state law. To effectuate the
foregoing intention, the Holders and such Guarantor hereby irrevocably agree
that the obligations of such Guarantor under its Guarantee shall be limited to
the maximum amount which, after giving effect to all other contingent and fixed
liabilities of such Guarantor and after giving effect to any

                                       - -
<PAGE>
collections from or payments made by or on behalf of any other Guarantor in
respect of the obligations of such other Guarantor under its Guarantee or
pursuant to its contribution obligations under this Indenture, will result in
the obligations of such Guarantor under its Guarantee not constituting such
fraudulent transfer or conveyance.

                  (b)      Each Guarantor that makes a payment or distribution
under its Guarantee shall be entitled to a contribution from each other
Guarantor, if any, in a pro rata amount based on the net assets of each
Guarantor, determined in accordance with GAAP.

                  (c)      Until the Securities are paid in full, each Guarantor
hereby waives all rights of subrogation or contribution, whether arising by
contract or operation of law (including, without limitation, any such right
arising under federal bankruptcy law) or otherwise by reason of any payment by
it pursuant to the provisions of this Article Fourteen.

         Section 1408.     Guarantee Is in Addition to Other Security.

                  This Guarantee shall be in addition to and not in substitution
for any other guarantees or other security which the Trustee may now or
hereafter hold in respect of the Indenture Obligations owing to the Trustee or
the Holders by the Company and (except as may be required by law) the Trustee
shall be under no obligation to marshal in favor of each of the Guarantors any
other guarantees or other security or any moneys or other assets which the
Trustee may be entitled to receive or upon which the Trustee or the Holders may
have a claim.

         Section 1409.     Release of Security Interests.

                  Without limiting the generality of the foregoing and except as
otherwise provided in this Indenture, each Guarantor hereby consents and agrees,
to the fullest extent permitted by applicable law, that the rights of the
Trustee hereunder, and the liability of the Guarantors hereunder, shall not be
affected by any and all releases for any purpose of any collateral, if any, from
the Liens and security interests created by any collateral document and that
this Guarantee shall continue to be effective or be reinstated, as the case may
be, if at any time any payment of any of the Indenture Obligations is rescinded
or must otherwise be returned by the Trustee upon the insolvency, bankruptcy or
reorganization of the Company or otherwise, all as though such payment had not
been made.

         Section 1410.     No Bar to Further Actions.

                  Except as provided by law, no action or proceeding brought or
instituted under Article Fourteen and this Guarantee and no recovery or judgment
in pursuance thereof shall be a bar or defense to any further action or
proceeding which may be brought under Article Fourteen and this Guarantee by
reason of any further default or defaults under Article Fourteen and this
Guarantee or in the payment of any of the Indenture Obligations owing by the
Company.

         Section 1411.     Failure to Exercise Rights Shall Not Operate as a
Waiver; No Suspension of Remedies.

                  (a)      No failure to exercise and no delay in exercising, on
the part of the Trustee or the Holders, any right, power, privilege or remedy
under this Article Fourteen and this

                                       - -
<PAGE>
Guarantee shall operate as a waiver thereof, nor shall any single or partial
exercise of any rights, power, privilege or remedy preclude any other or further
exercise thereof, or the exercise of any other rights, powers, privileges or
remedies. The rights and remedies herein provided for are cumulative and not
exclusive of any rights or remedies provided in law or equity.

                  (b)      Nothing contained in this Article Fourteen shall
limit the right of the Trustee or the Holders to take any action to accelerate
the maturity of the Securities pursuant to Article Five or to pursue any rights
or remedies hereunder or under applicable law.

         Section 1412.     Trustee's Duties; Notice to Trustee.

                  (a)      Any provision in this Article Fourteen or elsewhere
in this Indenture allowing the Trustee to request any information or to take any
action authorized by, or on behalf of, any Holder, shall be permissive and shall
not be obligatory on the Trustee except as the Holders may direct in accordance
with the provisions of this Indenture or where the failure of the Trustee to
request any such information or to take any such action arises from the
Trustee's gross negligence, bad faith or willful misconduct.

                  (b)      The Trustee shall not be required to inquire into the
existence, powers or capacities of the Company, any Guarantor or the officers,
directors or agents acting or purporting to act on their respective behalf.

         Section 1413.     Successors and Assigns.

                  Subject to Section 1414, all terms, agreements and conditions
of this Article Fourteen shall extend to and be binding upon each Guarantor and
its successors and permitted assigns and shall enure to the benefit of and may
be enforced by the Trustee and its successors and assigns; provided, however,
that the Guarantors may not assign any of their rights or obligations hereunder
other than in accordance with Article Eight.

         Section 1414.     Release of Guarantee.

                  Concurrently with the payment in full of all of the Indenture
Obligations, the Guarantors shall be released from and relieved of their
obligations under this Article Fourteen. Upon the delivery by the Company to the
Trustee of an Officers' Certificate and, if requested by the Trustee, an Opinion
of Counsel to the effect that the transaction giving rise to the release of this
Guarantee was made by the Company in accordance with the provisions of this
Indenture and the Securities, the Trustee shall execute any documents reasonably
required in order to evidence the release of the Guarantors from their
obligations under this Guarantee. If any of the Indenture Obligations are
revived and reinstated after the termination of this Guarantee, then all of the
obligations of the Guarantors under this Guarantee shall be revived and
reinstated as if this Guarantee had not been terminated until such time as the
Indenture Obligations are paid in full, and each Guarantor shall enter into an
amendment to this Guarantee, reasonably satisfactory to the Trustee, evidencing
such revival and reinstatement.

                  This Guarantee shall terminate with respect to each Guarantor
and shall be automatically and unconditionally released and discharged as
provided in Section 1013(c).

         Section 1415.     Execution of Guarantee.

                  (a)      To evidence the Guarantee, each Guarantor hereby
agrees to execute the guarantee substantially in the form set forth in Section
204, to be endorsed on each Security authenticated and delivered by the Trustee
and that this Indenture shall be executed on behalf of each Guarantor by its
Chairman of the Board, its President, its Chief Executive Officer, Chief
Operating Officer, Treasurer or one of its Assistant Treasurers or one of its
Vice Presidents, which signature shall be attested by its Clerk, Assistant
Clerk, its Secretary or one of its Assistant Secretaries. The signature of any
of these officers on the Securities may be manual or facsimile.

                  (b)      Any person that was not a Guarantor on the date of
this Indenture may become a Guarantor by executing and delivering to the Trustee
(i) a supplemental indenture in form reasonably satisfactory to the Trustee,
which subjects such person to the provisions (including the representations and
warranties) of this Indenture as a Guarantor, (ii) in the event that as of the
date of such supplemental indenture any Registrable Securities (as defined in
the Registration Rights Agreement) are outstanding, an instrument in form
reasonably satisfactory to the Trustee which subjects such person to the
provisions of the Registration Rights Agreement with respect to such outstanding
Registrable Securities, and (iii) an Opinion of Counsel to the effect that such
supplemental indenture has been duly authorized and executed by such person and
constitutes the legal, valid and binding obligation of such person (subject to
such customary assumptions and exceptions as may be acceptable to the Trustee in
its reasonable discretion).

                  (c)      If an officer whose signature is on this Indenture no
longer holds that office at the time the Trustee authenticates a Security on
which this Guarantee is endorsed, such Guarantee shall be valid nevertheless.

         Section 1416.     Guarantee Subordinate to Senior Guarantor
Indebtedness.

                  Each Guarantor covenants and agrees, and each Holder of a
Guarantee, by his acceptance thereof, likewise covenants and agrees, that, to
the extent and in the manner hereinafter set forth in this Article, the
Indebtedness represented by the Guarantees is hereby expressly made subordinate
and subject in right of payment as provided in this Article to the prior payment
in full in cash (or in any other form as acceptable to the holders of Senior
Guarantor Indebtedness) of all Senior Guarantor Indebtedness.

                  This Article Fourteen shall constitute a continuing offer to
all Persons who, in reliance upon such provisions, become holders of, or
continue to hold Senior Guarantor Indebtedness; and such provisions are made for
the benefit of the holders of Senior Guarantor Indebtedness; and such holders
are made obligees hereunder and they or each of them may enforce such
provisions.

         Section 1417.     Payment Over of Proceeds Upon Dissolution of the
Guarantor, etc.

                  In the event of (a) any insolvency or bankruptcy case or
proceeding, or any receivership, liquidation, reorganization or other similar
case or proceeding, relative to any Guarantor or to its assets, or (b) any
liquidation, dissolution or other winding up of any Guarantor, whether voluntary
or involuntary, or (c) any assignment for the benefit of creditors or any other
marshaling of assets or liabilities of any Guarantor, then and in any such
event:

                  (1)      the holders of Senior Guarantor Indebtedness shall be
entitled to receive payment in full in cash (or in any other form as acceptable
to the holders of Senior Guarantor Indebtedness) of all amounts due on or in
respect of all Senior Guarantor Indebtedness before the Holders of the
Securities are entitled to receive any payment or distribution of any kind or
character (other than any amounts previously set aside with the Trustee or
payments previously made, in either case, pursuant to the provisions described
under Article Four hereof) on account of the Guarantee of such Guarantor; and

                  (2)      any payment or distribution of assets of any
Guarantor of any kind or character, whether in cash, property or securities, by
set-off or otherwise, to which the Holders or the Trustee would be entitled but
for the provisions of this Article shall be paid by the liquidating trustee or
agent or other Person making such payment or distribution, whether a trustee in
bankruptcy, a receiver or liquidating trustee or otherwise, directly to the
holders of Senior Guarantor Indebtedness or their representative or
representatives or to the trustee or trustees under any indenture under which
any instruments evidencing any of such Senior Guarantor Indebtedness may have
been issued, ratably according to the aggregate amounts remaining unpaid on
account of the Senior Guarantor Indebtedness held or represented by each, to the
extent necessary to make payment in full in cash (or in any other form as
acceptable to the holders of Senior Guarantor Indebtedness) of all Senior
Guarantor Indebtedness remaining unpaid, after giving effect to any concurrent
payment or distribution to the holders of such Senior Guarantor Indebtedness;
and

                  (3)      in the event that, notwithstanding the foregoing
provisions of this Section, the Trustee or the Holder of any Security shall have
received any payment or distribution of assets of any Guarantor of any kind or
character, whether in cash, property or securities, in respect the Guarantee of
such Guarantor before all Senior Guarantor Indebtedness is paid in full in cash
(or in any other form as acceptable to the holders of Senior Guarantor
Indebtedness), then and in such event such payment or distribution shall be paid
over or delivered forthwith to the trustee in bankruptcy, receiver, liquidating
trustee, custodian, assignee, agent or other Person making payments or
distributions of assets of such Guarantor for application to the payment of all
Senior Guarantor Indebtedness remaining unpaid, to the extent necessary to pay

acceptable to the holders of Senior Guarantor Indebtedness) after giving effect
to any concurrent payment or distribution to or for the holders of Senior
Guarantor Indebtedness.

                  The consolidation of any Guarantor with, or the merger of any
Guarantor with or into, another Person or the liquidation or dissolution of any
Guarantor following the sale, assignment, conveyance, transfer, lease or other
disposal of its properties and assets substantially as an entirety to another
Person upon the terms and conditions set forth in Article Eight shall not be
deemed a dissolution, winding up, liquidation, reorganization, assignment for
the benefit of creditors or marshaling of assets and liabilities of such
Guarantor for the purposes of this Section if the Person formed by such
consolidation or the surviving entity of such merger or the Person which
acquires by sale, assignment, conveyance, transfer, lease or other disposal of
such properties and assets substantially as an entirety, as the case may be,
shall, as a part of such consolidation, merger, sale, assignment, conveyance,
transfer, lease or other disposal, comply with the conditions set forth in

Senior Guarantor Indebtedness) or such payment duly provided for before any

of the Guarantors in respect of the Guarantee of such Guarantor.

                  (b)      No payment shall be made by any Guarantor in respect

Guarantor shall make any payment to the Trustee or the Holder of its Guarantee
prohibited by the foregoing provisions of this Section, then and in such event
such payment shall be paid over and delivered forthwith to the representatives
of the holders of the Senior Guarantor Indebtedness or as a court of competent

the conditions described in Section 1418, from making payments at any time of

are intended solely for the purpose of defining the relative rights of the
Holders of the Securities on the one hand and the holders of Senior Guarantor
Indebtedness on the other hand. Nothing contained in this Article or elsewhere
in this Indenture or in the Securities is intended to or shall (a) impair, as

Indebtedness and the Holders of the Securities, the obligation such Guarantor,

dissolution, liquidation or other winding up, assignment for the benefit of
creditors or other marshaling of assets and liabilities of the Guarantors
referred to in Section 1417, to receive, pursuant to and in accordance with such
Section, cash, property and securities otherwise payable or deliverable to the

to prevent any payment prohibited by such Section or enforce their rights
pursuant to Section 1418(c).

         Section 1422.     Trustee to Effectuate Subordination.

                  Each Holder of a Security by such Holder's acceptance thereof
authorizes and directs the Trustee on such Holder's behalf to take such action
as may be necessary or appropriate to effectuate the subordination provided in
this Article and appoints the Trustee such Holder's attorney-in-fact for any and
all such purposes, including, in the event of any dissolution, winding-up,
liquidation or reorganization of any Guarantor whether in bankruptcy,
insolvency, receivership proceedings, or otherwise, the timely filing of a claim
for the unpaid balance of the indebtedness of any Guarantor owing to such Holder
in the form required in such proceedings and the causing of such claim to be
approved.

          Section 1423.    No Waiver of Subordination Provisions.

                  (a)      No right of any present or future holder of any
Senior Guarantor Indebtedness to enforce subordination as herein provided shall
at any time in any way be prejudiced or impaired by any act or failure to act on
the part of any Guarantor or by any act or failure to act, in good faith, by any
such holder, or by any non-compliance by any Guarantor with the terms,
provisions and covenants of this Indenture, regardless of any knowledge thereof
any such holder may have or be otherwise charged with.

                  (b)      Without limiting the generality of subsection (a) of
this Section, the holders of Senior Guarantor Indebtedness may, at any time and
from time to time, without the consent of or notice to the Trustee or the
Holders of the Securities, without incurring responsibility to the Holders of
the Securities and without impairing or releasing the subordination provided in
this Article or the obligations hereunder of the Holders of the

                                       - -
<PAGE>
Securities to the holders of Senior Guarantor Indebtedness, do any one or more
of the following: (1) change the manner, place or terms of payment or extend the
time of payment of, or renew or alter, Senior Guarantor Indebtedness or any
instrument evidencing the same or any agreement under which Senior Guarantor
Indebtedness is outstanding; (2) sell, exchange, release or otherwise deal with
any property pledged, mortgaged or otherwise securing Senior Guarantor
Indebtedness; (3) release any Person liable in any manner for the collection or
payment of Senior Guarantor Indebtedness; and (4) exercise or refrain from
exercising any rights against any of the Guarantors and any other Person;
provided, however, that in no event shall any such actions limit the right of
the Holders of the Securities to take any action to accelerate the maturity of
the Securities pursuant to Article Five of this Indenture or to pursue any
rights or remedies hereunder or under applicable laws if the taking of such
action does not otherwise violate the terms of this Article.

         Section 1424.     Notice to Trustee by Each of the Guarantors.

                  (a)      Each Guarantor shall give prompt written notice to
the Trustee of any fact known to such Guarantor which would prohibit the making
of any payment to or by the Trustee in respect of the Guarantee. Notwithstanding
the provisions of this Article or any other provision of this Indenture, the
Trustee shall not be charged with knowledge of the existence of any facts which
would prohibit the making of any payment to or by the Trustee in respect of the
Securities, unless and until the Trustee shall have received written notice
thereof from any Guarantor or a holder of Senior Guarantor Indebtedness or any
trustee, fiduciary or agent therefor; and, prior to the receipt of any such
written notice, the Trustee shall be entitled in all respects to assume that no
such facts exist; provided, however, that if the Trustee shall not have received
the notice provided for in this Section by Noon, Eastern Time, on the Business
Day prior to the date upon which by the terms hereof any money may become
payable for any purpose (including, without limitation, the payment of the
principal of, premium, if any, or interest on any Security), then, anything
herein contained to the contrary notwithstanding but without limiting the rights
and remedies of the holders of Senior Guarantor Indebtedness or any trustee,
fiduciary or agent thereof, the Trustee shall have full power and authority to
receive such money and to apply the same to the purpose for which such money was
received and shall not be affected by any notice to the contrary which may be
received by it after such date; nor shall the Trustee be charged with knowledge
of the curing of any such default or the elimination of the act or condition
preventing any such payment unless and until the Trustee shall have received an
Officers' Certificate to such effect.

                  (b)      The Trustee shall be entitled to rely on the delivery
to it of a written notice to the Trustee and each Guarantor by a Person which
represents itself as a representative of one or more holders of Guarantor Senior
or a holder of Senior Guarantor Indebtedness (or a trustee, fiduciary or agent
therefor) to establish that such notice has been given by a representative of or
a holder of Senior Guarantor Indebtedness (or a trustee, fiduciary or agent
therefor); provided, however, that failure to give such notice to the Company or
any Guarantor shall not affect in any way the ability of the Trustee to rely on
such notice. In the event that the Trustee determines in good faith that further
evidence is required with respect to the right of any Person as a holder of
Senior Guarantor Indebtedness to participate in any payment or distribution
pursuant to this Article, the Trustee may request such Person to furnish
evidence to the reasonable satisfaction of the Trustee as to the amount of
Senior Guarantor Indebtedness held by such Person, the extent to

                                       - -
<PAGE>
which such Person is entitled to participate in such payment or distribution and
any other facts pertinent to the rights of such Person under this Article, and
if such evidence is not furnished, the Trustee may defer any payment to such
Person pending judicial determination as to the right of such Person to receive
such payment.

         Section 1425.     Reliance on Judicial Orders or Certificates.

                  Upon any payment or distribution of assets of any Guarantor
referred to in this Article, the Trustee and the Holders of the Securities shall
be entitled to rely upon any order or decree entered by any court of competent
jurisdiction in which such insolvency, bankruptcy, receivership, liquidation,
reorganization, dissolution, winding up or similar case or proceeding is
pending, or a certificate of the trustee in bankruptcy, receiver, liquidating
trustee, custodian, assignee for the benefit of creditors, agent or other person
making such payment or distribution, delivered to the Trustee or to the Holders
of Securities for the purpose of ascertaining the Persons entitled to
participate in such payment or distribution, the holders of Senior Guarantor
Indebtedness and other indebtedness of such Guarantor, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts pertinent thereto or to this Article, provided that the foregoing shall
apply only if such court has been fully apprised of the provisions of this
Article.

         Section 1426.     Rights of Trustee as a Holder of Senior Guarantor
Indebtedness; Preservation of Trustee's Rights.

                  The Trustee in its individual capacity shall be entitled to
all the rights set forth in this Article with respect to any Senior Guarantor
Indebtedness which may at any time be held by it, to the same extent as any
other holder of Senior Guarantor Indebtedness, and nothing in this Indenture
shall deprive the Trustee of any of its rights as such holder. Nothing in this
Article shall apply to claims of, or payments to, the Trustee under or pursuant
to Section 607.

         Section 1427.     Article Applicable to Paying Agents.

                  In case at any time any Paying Agent other than the Trustee
shall have been appointed by the Company and be then acting under this
Indenture, the term "Trustee" as used in this Article shall in such case (unless
the context otherwise requires) be construed as extending to and including such
Paying Agent within its meaning as fully for all intents and purposes as if such
Paying Agent were named in this Article in addition to or in place of the
Trustee; provided, however, that Section 1426 shall not apply to the Company or
any Affiliate of the Company if it or such Affiliate acts as Paying Agent.

         Section 1428.     No Suspension of Remedies.

                  Nothing contained in this Article shall limit the right of the
Trustee or the Holders of Securities to take any action to accelerate the
maturity of the Securities pursuant to Article Five of this Indenture or to
pursue any rights or remedies hereunder or under applicable law, subject to the
rights, if any, under this Article of the holders, from time to time, of Senior
Guarantor Indebtedness to receive the cash, property or securities receivable
upon the exercise of such rights or remedies.

         Section 1429.     Trustee's Relation to Senior Guarantor Indebtedness.

                  With respect to the holders of Senior Guarantor Indebtedness,
the Trustee undertakes to perform or to observe only such of its covenants and
obligations as are specifically set forth in this Article, and no implied
covenants or obligations with respect to the holders of Senior Guarantor
Indebtedness shall be read into this Article against the Trustee. The Trustee
shall not be deemed to owe any fiduciary duty to the holders of Senior Guarantor
Indebtedness and the Trustee shall not be liable to any holder of Senior
Guarantor Indebtedness if it shall in good faith mistakenly (absent willful
misconduct) pay over or deliver to Holders, the Company or any other Person
moneys or assets to which any holder of Senior Guarantor Indebtedness shall be
entitled by virtue of this Article or otherwise.

Securities or any Guarantees, including without limitation, any Indebtedness
incurred under the Credit Agreement, shall be third party beneficiaries to this
intercompany note and upon an Event of Default shall have the right to enforce

                           been made in the United States by or on behalf of the
