that office at the time a Note is authenticated, the Note shall nevertheless be
valid.

                  A Note shall not be valid until authenticated by the manual

Note has been authenticated under this Indenture.

                  The aggregate principal amount of Notes which may be
authenticated and delivered under this Indenture is unlimited.

                  The Trustee shall, upon a written order of the Company signed

receipt of an Authentication Order, the Trustee shall authenticate for original
issue (i) Exchange Notes in exchange for Initial Notes in an aggregate principal
amount not to exceed $160,000,000 or (ii) Exchange Notes in exchange for
Additional Notes; provided that such Exchange Notes shall be issuable only upon
the valid surrender for cancellation of Initial Notes issued on the date hereof
or Additional Notes, as the case may be, of a like aggregate principal amount in
accordance with an Exchange Offer pursuant to an applicable Registration Rights
Agreement.

                  The Trustee may appoint an authenticating agent acceptable to
the Company to authenticate Notes. An authenticating agent may authenticate

authentication by the Trustee includes authentication by such agent. An

Affiliate of the Company.

accordance with those instructions. All other payments on Notes shall be made at
the office or agency of the Paying Agent and Registrar within the City and State
of New York unless the Company elects to make interest payments by check mailed
to the Holders at their addresses set forth in the register of Holders. Payments

or more additional paying agents. The term "Registrar" includes any co-registrar
and the term "Paying Agent" includes any additional paying agent. The Company
may change any Paying Agent or Registrar without prior notice to any Holder. The
Company shall notify the Trustee in writing of the name and address of any Agent
not a party to this Indenture. If the Company fails to appoint or maintain
another entity as Registrar or Paying Agent, the Trustee shall act as such. The
Company or any of its Subsidiaries may act as Paying Agent or Registrar.

                  (b)      The Company initially appoints DTC to act as
Depositary with respect to the Global Notes.

benefit of the Holders or the Trustee all money held by the Paying Agent for the
payment of principal or premium, if any, or interest on the Notes, and shall
notify the Trustee of any default by the Company in making any such payment.
While any such default continues, the Trustee may require a Paying Agent to pay
all money held by it to the Trustee. The Company at any time may require a
Paying Agent to pay all money held by it to the Trustee. Upon payment over to
the Trustee, the Paying Agent (if other than the Company or one of its
Subsidiaries) shall have no further liability for the money. If the Company or
any of its Subsidiaries acts as Paying Agent, it shall segregate and hold in a
separate trust fund for the benefit of the Holders all money held by it as
Paying Agent. Upon any bankruptcy or reorganization proceedings relating to the
Company, the Trustee shall serve as Paying Agent for the Notes.

                  The Trustee shall preserve in as current a form as is
reasonably practicable the most recent list available to it of the names and
addresses of all Holders and shall otherwise comply with TIA Section 312(a). If
the Trustee is not the Registrar, the Company shall furnish to the Trustee at
least seven Business Days before each interest payment date and at such other
times as the Trustee

Section 2.07. Transfer and Exchange.

                  (a)      Transfer and Exchange of Global Notes. A Global Note
may not be transferred as a whole except by the Depositary to a nominee of the
Depositary, by a nominee of the Depositary to the Depositary or to another
nominee of the Depositary, or by the Depositary or any such nominee to a
successor Depositary or a nominee of such successor Depositary. All Global Notes
shall be exchanged by the Company for Definitive Notes if (i) the Company
delivers to the Trustee notice from the Depositary that it is unwilling or
unable to continue to act as Depositary or that it is no longer a clearing
agency registered under the Exchange Act and, in either case, a successor
Depositary is not appointed by the Company within 90 days after the date of such
notice from the Depositary; (ii) the Company in its sole discretion determines
that the Global Notes (in whole but not in part) should be exchanged for
Definitive Notes and delivers a written notice to such effect to the Trustee;
provided that in no event shall the Regulation S Temporary Global Note be
exchanged by the Company for Definitive Notes prior to (x) the expiration of the
Restricted Period and (y) the receipt by the Registrar of any certificates
required pursuant to Rule 903(b)(3)(ii)(B) under the Securities Act; or (iii)
there shall have occurred and be continuing a Default or Event of Default with
respect to the Notes. Upon the occurrence of any of the preceding events in (i),
(ii) or (iii) above, Definitive Notes shall be issued in such names as the
Depositary shall instruct the Trustee. Global Notes also may be exchanged or
replaced, in whole or in part, as provided in Sections 2.08 and 2.11 hereof.
Every Note authenticated and delivered in exchange for, or in lieu of, a Global
Note or any portion thereof, pursuant to this Section 2.07 or Section 2.08 or
2.11 hereof, shall be authenticated and delivered in the form of, and shall be,
a Global Note. A Global Note may not be exchanged for another Note other than as
provided in this Section 2.07(a), however, beneficial interests in a Global Note
may be transferred and exchanged as provided in Section 2.07(b), (c) or (f)
hereof.

                  (b)      Transfer and Exchange of Beneficial Interests in the
Global Notes. The transfer and exchange of beneficial interests in the Global
Notes shall be effected through the Depositary, in accordance with the
provisions of this Indenture and the Applicable Procedures. Beneficial interests
in the Restricted Global Notes shall be subject to restrictions on transfer
comparable to those set forth herein to the extent required by the Securities
Act. Transfers of beneficial interests in the Global Notes also shall require
compliance with either subparagraph (i) or (ii) below, as applicable, as well as
one or more of the other following subparagraphs, as applicable:

                           (i)      Transfer of Beneficial Interests in the Same
                  Global Note. Beneficial interests in any Restricted Global
                  Note may be transferred to Persons who take delivery thereof
                  in the form of a beneficial interest in the same Restricted
                  Global Note in accordance with the transfer restrictions set
                  forth in the Private Placement Legend; provided, however, that
                  prior to the expiration of the Restricted Period, transfers of
                  beneficial interests in the Regulation S Temporary Global Note
                  may not be made to a U.S. Person or for the account or benefit
                  of a U.S. Person (other than an Initial Purchaser). Beneficial
                  interests in any Unrestricted Global Note may be transferred
                  to Persons who take delivery thereof

                  transferred or exchanged and (2) instructions given in
                  accordance with the Applicable Procedures containing
                  information regarding the Participant account to be credited

                  Registrar containing information regarding the Person in whose
                  name such Definitive Note shall be registered to effect the
                  transfer or exchange referred to in (1) above; provided that
                  in no event shall Definitive Notes be issued upon the transfer
                  or exchange of beneficial interests in the Regulation S
                  Temporary Global Note prior to (x) the expiration of the
                  Restricted Period and (y) the receipt by the Registrar of any
                  certificates required pursuant to Rule 903 under the
                  Securities Act. Upon consummation of an Exchange Offer by the
                  Company in accordance with Section 2.07(f) hereof, the
                  requirements of this Section 2.07(b)(ii) shall be deemed to

                  takes delivery thereof in the form of a beneficial interest in
                  another Restricted Global Note if the transfer complies with

                  for a beneficial interest in an Unrestricted Global Note or

                           Registrar to the effect that such exchange or
                           transfer is in compliance with the Securities Act and
                           that the restrictions on transfer contained herein
                           and in the Private Placement Legend are no longer
                           required in order to maintain compliance with the
                           Securities Act.

                           Upon satisfaction of the conditions of any of the
                  subparagraphs in this Section 2.07(d)(ii), the Trustee shall
                  cancel the Definitive Notes and increase or cause to be
                  increased the aggregate principal amount of the Unrestricted
                  Global Note.

                           (iii)    Unrestricted Definitive Notes to Beneficial
                  Interests in Unrestricted Global Notes. A Holder of an
                  Unrestricted Definitive Note may exchange such Note for a
                  beneficial interest in an Unrestricted Global Note or transfer
                  such Definitive Notes to a Person who takes delivery thereof
                  in the form of a beneficial interest in an Unrestricted Global
                  Note at any time. Upon receipt of a request for such an
                  exchange or transfer, the Trustee shall cancel the applicable
                  Unrestricted Definitive Note and increase or cause to be
                  increased the aggregate principal amount of one of the
                  Unrestricted Global Notes.

         Note to a beneficial interest is effected pursuant to subparagraphs
         (ii)(B), (ii)(D) or (iii) above at a time when an Unrestricted Global
         Note has not yet been issued, the Company shall issue and, upon receipt
         of an Authentication Order in accordance with Section 2.02 hereof, the
         Trustee shall authenticate one or more Unrestricted Global Notes in an
         aggregate principal amount equal to the principal amount of Definitive

Definitive Notes. Upon request by a Holder of Definitive Notes and such Holder's
compliance with the provisions of this Section 2.07(e), the Registrar shall
register the transfer or exchange of Definitive Notes. Prior to such
registration of transfer or exchange, the requesting Holder shall present or
surrender to the Registrar the Definitive Notes duly endorsed or accompanied by
a written instruction of transfer in form satisfactory to the Registrar duly

                           (i)      Restricted Definitive Notes to Restricted
                  Definitive Notes. Any Restricted Definitive Note may be
                  transferred to and registered in the name of Persons who take

                  cover any transfer tax or similar governmental charge payable
                  in connection therewith (other than any such transfer taxes or
                  similar governmental charge payable upon exchange or transfer
                  pursuant to Sections 2.11, 3.06, 3.09, 4.10, 4.15 and 9.05
                  hereof).

                           (iii)    The Registrar shall not be required to
                  register the transfer of or exchange any Note selected for
                  redemption in whole or in part, except the unredeemed portion
                  of any Note being redeemed in part.

                           (iv)     All Global Notes and Definitive Notes issued
                  upon any registration of transfer or exchange of Global Notes
                  or Definitive Notes shall be the valid and legally binding
                  obligations of the Company, evidencing the same debt, and
                  entitled to the same benefits under this Indenture, as the
                  Global Notes or Definitive Notes surrendered upon such
                  registration of transfer or exchange.

                           (v)      The Company shall not be required (A) to
                  issue, to register the transfer of or to exchange any Notes
                  during a period beginning at the opening of business 15 days
                  before the day of any selection of Notes for redemption under
                  Section 3.02 hereof and ending at the close of business on the
                  day of selection, (B) to register the transfer of or to
                  exchange any Note so selected for redemption in whole or in
                  part, except the unredeemed portion of any Note being redeemed
                  in part or (C) to register the transfer of or to exchange a
                  Note between a record date and the next succeeding interest
                  payment date.

                           (vi)     Prior to due presentment for the
                  registration of a transfer of any Note, the Trustee, any Agent
                  and the Company may deem and treat the Person in whose name
                  any Note is registered as the absolute owner of such Note for
                  the purpose of receiving payment of principal of and interest
                  on such Notes and for all other purposes, and none of the
                  Trustee, any Agent or the Company shall be affected by notice
                  to the contrary.

                           (vii)    The Trustee shall authenticate Global Notes
                  and Definitive Notes in accordance with the provisions of
                  Section 2.02 hereof.

                           (viii)   All certifications, certificates and

Section 2.08. Replacement Notes.

                  (a)      If any mutilated Note is surrendered to the Trustee
or the Company and the Trustee receives evidence to its satisfaction of the
destruction, loss or theft of any Note, the Company shall issue and the Trustee,
upon receipt of an Authentication Order, shall authenticate a replacement Note
if the Trustee's requirements are met. If required by the Trustee or the
Company, an indemnity bond must be supplied by the Holder that is sufficient in
the judgment of the Trustee and the Company to protect the Company, the Trustee,
any Agent and any authenticating agent from any loss that any of them may suffer
if a Note is replaced. The Company may charge for its expenses in replacing a
Note.

                  (b)      Every replacement Note is an additional obligation of
the Company and shall be entitled to all of the benefits of this Indenture
equally and proportionately with all other Notes duly issued hereunder.

Section 2.09. Outstanding Notes.

                  (a)      The Notes outstanding at any time are all the Notes
authenticated by the Trustee except for those canceled by it, those delivered to
it for cancellation, those reductions in the interest in a Global Note effected
by the Trustee in accordance with the provisions hereof, and those described in
this Section as not outstanding. Except as set forth in Section 2.10 hereof, a
Note does not cease to be outstanding because the Company or an Affiliate of the
Company holds the Note; however, Notes held by the Company or a Subsidiary of
the Company shall not be deemed to be outstanding for purposes of Section
3.07(b) hereof.

                  (b)      If a Note is replaced pursuant to Section 2.08
hereof, it ceases to be outstanding unless the Trustee receives proof
satisfactory to it that the replaced Note is held by a protected purchaser.

                  (c)      If the principal amount of any Note is considered
paid under Section 4.01 hereof, it ceases to be outstanding and interest on it
ceases to accrue.

                  (d)      If the Paying Agent (other than the Company, a
Subsidiary or an Affiliate of any of the foregoing) holds, on a redemption date
or maturity date, money sufficient to pay Notes payable on that date, then on
and after that date such Notes shall be deemed to be no longer outstanding and
shall cease to accrue interest.

Section 2.10. Treasury Notes.

                  In determining whether the Holders of the required principal
amount of Notes have concurred in any direction, waiver or consent, Notes owned
by the Company, or by any Person directly or indirectly controlling or
controlled by or under direct or indirect common control with the Company, shall
be considered as though not outstanding, except that for the purposes of
determining whether the Trustee shall be protected in relying on any such
direction, waiver or consent, only Notes that the Trustee knows are so owned
shall be so disregarded.

Section 2.11. Temporary Notes.

                  (a)      Until certificates representing Notes are ready for
delivery, the Company may prepare and the Trustee, upon receipt of an
Authentication Order, shall authenticate temporary Notes. Temporary Notes shall
be substantially in the form of Definitive Notes but may have variations that
the Company considers appropriate for temporary Notes and as shall be reasonably
acceptable to the Trustee. Without unreasonable delay, the Company shall prepare
and the Trustee shall authenticate Definitive Notes in exchange for temporary
Notes.

                  (b)      Holders of temporary Notes shall be entitled to all
of the benefits of this Indenture.

Section 2.12. Cancellation.

                  The Company at any time may deliver Notes to the Trustee for
cancellation. The Registrar and Paying Agent shall forward to the Trustee any
Notes surrendered to them for registration of transfer, exchange or payment. The
Trustee and no one else shall cancel all Notes surrendered for registration of
transfer, exchange, payment, replacement or cancellation and shall dispose of
canceled Notes in accordance with its procedures for the disposition of canceled
securities in effect as of the date of such disposition (subject to the record
retention requirement of the Exchange Act). Certification of the disposition of
all canceled Notes shall be delivered to the Company. The Company may not issue
new Notes to replace Notes that it has paid or that have been delivered to the
Trustee for cancellation.

Section 2.13. Defaulted Interest.

                  If the Company defaults in a payment of interest on the Notes,
it shall pay the defaulted interest in any lawful manner plus, to the extent
lawful, interest payable on the defaulted interest, to the Persons who are
Holders on the record date for the interest payment or a subsequent special
record date, in each case at the rate provided in the Notes and in Section 4.01
hereof. The Company shall notify the Trustee in writing of the amount of
defaulted interest proposed to be paid on each Note and the date of the proposed
payment. The Company shall fix or cause to be fixed each such special record
date and payment date, provided that no such special record date shall be less
than 5 days prior to the related payment date for such defaulted interest. At
least 5 days before the special record date, the Company (or, upon the written
request of the Company, the Trustee in the name and at the expense of the
Company) shall mail or cause to be mailed to Holders a notice that states the
special record date, the related payment date and the amount of such interest to
be paid.

Section 2.14. CUSIP Numbers.

                  The Company in issuing the Notes may use "CUSIP" numbers (if
then generally in use), and, if so, the Trustee shall use "CUSIP" numbers in
notices of redemption as a convenience to Holders; provided that any such notice
may state that no representation is made as to the correctness of such numbers
either as printed on the Notes or as contained in any notice of a redemption and
that reliance may be placed only on the other identification numbers printed on
the Notes, and any such redemption shall not be affected by any defect in or
omission of such

                                     - 42 -
<PAGE>

numbers. The Company shall promptly notify the Trustee of any change in the
"CUSIP" numbers.

Section 3.01. Notices to Trustee.

                  If the Company elects to redeem Notes pursuant to the optional
redemption provisions of Section 3.07 hereof, it shall furnish to the Trustee,
at least 30 days but not more than 60 days before a redemption date, an
Officers' Certificate setting forth (i) the clause of this Indenture pursuant to
which the redemption shall occur, (ii) the redemption date, (iii) the principal
amount of Notes to be redeemed and (iv) the redemption price.

Section 3.02. Selection of Notes to Be Redeemed.

                  (a)      If less than all of the Notes are to be redeemed or
purchased in an offer to purchase at any time, the Trustee shall select the
Notes to be redeemed or purchased among the Holders of the Notes not more than
90 days prior to the redemption date, or otherwise in compliance with the
requirements of the principal national securities exchange, if any, on which the
Notes are listed or, if the Notes are not so listed, on a pro rata basis, by lot
or in accordance with any other method the Trustee considers fair and
appropriate. In the event of partial redemption by lot, the particular Notes to
be redeemed shall be selected, unless otherwise provided herein, not less than
30 nor more than 60 days prior to the redemption date by the Trustee from the
outstanding Notes not previously called for redemption.

                  (b)      The Trustee shall promptly notify the Company in
writing of the Notes selected for redemption and, in the case of any Note
selected for partial redemption, the principal amount at maturity thereof to be
redeemed. No Notes in amounts of $1,000 or less shall be redeemed in part. Notes
and portions of Notes selected shall be in amounts of $1,000 or whole multiples
of $1,000; except that if all of the Notes of a Holder are to be redeemed, the
entire outstanding amount of Notes held by such Holder, even if not a multiple
of $1,000, shall be redeemed. Except as provided in the preceding sentence,
provisions of this Indenture that apply to Notes called for redemption also
apply to portions of Notes called for redemption.

Section 3.03. Notice of Redemption.

                  (a)      Subject to the provisions of Section 3.09 hereof, at
least 30 days but not more than 60 days before a redemption date, the Company
shall mail or cause to be mailed, by first class mail, a notice of redemption to
each Holder whose Notes are to be redeemed at its registered address.

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

                           (i)      the redemption date;

                           (ii)     the redemption price;

<PAGE>

                           (iii)    if any Note is being redeemed in part, the
                  portion of the principal amount at maturity of such Note to be
                  redeemed and that, after the redemption date upon surrender of
                  such Note, a new Note or Notes in principal amount equal to
                  the unredeemed portion of the original Note shall be issued in
                  the name of the Holder thereof upon cancellation of the
                  original Note;

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

                           (v)      that Notes called for redemption must be
                  surrendered to the Paying Agent to collect the redemption
                  price and become due on the date fixed for redemption;

                           (vi)     that, unless the Company defaults in making
                  such redemption payment, interest, if any, on Notes called for
                  redemption ceases to accrue on and after the redemption date;

                           (vii)    the paragraph of the Notes and/or Section of
                  this Indenture pursuant to which the Notes called for
                  redemption are being redeemed; and

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

                  (b)      At the Company's request, the Trustee shall give the
notice of redemption in the Company's name and at its expense; provided,
however, that the Company shall have delivered to the Trustee, at least 45 days
prior to the redemption date (or such shorter period of time as the Trustee may
allow), an Officers' Certificate requesting that the Trustee give such notice
and setting forth the information to be stated in such notice as provided in the
preceding paragraph. The notice, if mailed in the manner provided herein shall
be presumed to have been given, whether or not the Holder receives such notice.

Section 3.04. Effect of Notice of Redemption.

                  Once notice of redemption is mailed in accordance with Section
3.03 hereof, Notes called for redemption become irrevocably due and payable on
the redemption date at the redemption price. A notice of redemption may not be
conditional except for in the case of a Change of Control Offer pursuant to
Section 4.15 herein.

Section 3.05. Deposit of Redemption Price.

                  (a)      On or prior to 12:00 p.m. Eastern Time on the
redemption date, the Company shall deposit in immediately available funds with
the Trustee or with the Paying Agent money sufficient to pay the redemption
price of and accrued interest on all Notes to be redeemed on that date. The
Trustee or the Paying Agent shall promptly return to the Company any money
deposited with the Trustee or the Paying Agent by the Company in excess of the
amounts necessary to pay the redemption price of, and accrued interest on, all
Notes to be redeemed.

                  (b)      If the Company complies with the provisions of the
preceding paragraph, on and after the redemption date, interest shall cease to
accrue on the Notes or the portions of

                                     - 44 -
<PAGE>

Notes called for redemption. If a Note is redeemed on or after an interest
record date but on or prior to the related interest payment date, then any
accrued and unpaid interest shall be paid to the Holder in whose name such Note
was registered at the close of business on such record date. If any Note called
for redemption shall not be so paid upon surrender for redemption because of the
failure of the Company to comply with the preceding paragraph, interest shall be
paid on the unpaid principal, from the redemption date until such principal is
paid, and to the extent lawful on any interest not paid on such unpaid
principal, in each case at the rate provided in the Notes and in Section 4.01
hereof.

Section 3.06. Notes Redeemed in Part.

                  Upon surrender of a Note that is redeemed in part, the Company
shall issue and the Trustee shall authenticate for the Holder at the expense of
the Company a new Note equal in principal amount to the unredeemed portion of
the Note surrendered. No Notes in denominations of $1,000 or less shall be
redeemed in part.

Section 3.07. Optional Redemption.

                  (a)      At any time on or prior to November 1, 2007, the
Company may, on any one or more occasions, redeem all or a portion of the Notes,
on not less than 30 nor more than 60 days' prior notice, in amounts of $1,000 or
an integral multiple thereof, at a price equal to the greater of:

                           (i)      100% of the aggregate principal amount of
                  the Notes to be redeemed, together with accrued and unpaid
                  interest, if any, to the date of redemption, and

                           (ii)     as determined by an Independent Investment
                  Banker, the sum of the present values of 104.500% of the
                  principal of the Notes being redeemed plus scheduled payments
                  of interest (not including any portion of such payments of
                  interest accrued as of the date of redemption) from the date
                  of redemption to November 1, 2007 discounted for each such
                  amount to the redemption date on a semiannual basis (assuming
                  a 360-day year consisting of twelve 30-day months) at the
                  Adjusted Treasury Rate plus 50 basis points, together with
                  accrued and unpaid interest, if any, to the date of
                  redemption.

                  (b)      After November 1, 2007, the Notes will be redeemable,
at the option of the Company, as a whole or from time to time in part, on not
less than 30 nor more than 60 days' prior notice to the Holders at the following
redemption prices (expressed as percentages of principal amount), together with
accrued interest, if any, to the redemption date (subject to the right of
Holders of record on the relevant record date to receive interest due on an
interest payment date), if redeemed during the 12-month period beginning on
November 1 of the years indicated below.

hereunder with the net proceeds of one or more Public Equity Offerings at a

payment date); provided that, immediately after giving effect to such
redemption, at least 65% of the aggregate principal amount of the Notes issued
under this Indenture remains outstanding; provided further that such redemptions
shall occur within 90 days of the date of the closing of each such Public Equity
Offering.

                  The Excess Proceeds Offer shall remain open for a period of
not less than 30 and not more than 60 Business Days following its commencement

Date;

                  (c)      that any Note not tendered or accepted for payment
shall continue to accrete or accrue interest;

pursuant to a Excess Proceeds Offer may elect to have Notes purchased in
integral multiples of $1,000 only;

                  (f)      that Holders electing to have a Note purchased

depositary, if appointed by the Company, or a Paying Agent at the address
specified in the notice at least three days before the Purchase Date;

                  (g)      that Holders shall be entitled to withdraw their
election if the Company, the Depositary or the Paying Agent, as the case may be,
receives, not later than the expiration of the Offer Period, a telegram, telex,
facsimile transmission or letter setting forth the name of the Holder, the
principal amount of the Note the Holder delivered for purchase and a statement
that such Holder is withdrawing its election to have such Note purchased;

                  (h)      that, if the aggregate amount of Notes surrendered by
Holders exceeds the Offer Amount, the Trustee shall select the Notes to be
purchased pursuant to the terms of Section 3.02 hereof (with such adjustments as
may be deemed appropriate by the Trustee so that only Notes in denominations of
$1,000, or integral multiples thereof, shall be purchased); and

                  (i)      that Holders whose Notes were purchased only in part
shall be issued new Notes equal in principal amount to the unpurchased portion

                  simultaneously with such repurchase, the Company has made the
                  Change of Control Offer as provided in Section 4.15 hereof
                  with respect to the Notes and has repurchased all Notes
                  validly tendered for payment in connection with such Change of
                  Control Offer;

                           (vi)     the purchase, redemption, acquisition,
                  cancellation or other retirement for value of shares of
                  Capital Stock of the Company, options on any such shares or
                  related stock appreciation rights or similar securities, in
                  each case held by officers, directors or employees or former
                  officers, directors or employees (or their spouses,
                  descendants (natural or adopted), any trust established and
                  maintained for the benefit of such Person, his spouse or
                  descendants, or their estates or beneficiaries under their
                  estates) of the Company or any Restricted Subsidiary of the
                  Company, as applicable, or by any employee benefit plan of the
                  Company or any Restricted Subsidiary of the Company, as
                  applicable, upon death, disability, retirement or termination
                  of employment or pursuant to the terms of any employee benefit
                  plan or any other agreement under which such shares of stock
                  or related rights were issued; provided that the aggregate
                  amount of cash applied by the Company for such purchase,
                  redemption, acquisition, cancellation or other retirement of
                  such shares of Capital Stock of the Company after the Closing
                  Date does not exceed (i) $2.5 million in any given year,
                  provided however, that any unused amount in any given year
                  pursuant to this clause (i) may be carried forward to increase
                  the amount available pursuant to this clause (i) in the next
                  succeeding year (including successive carryforwards), and (ii)
                  $7.5 million in the aggregate during the term of the Notes
                  (excluding for purposes of calculating such amount the
                  aggregate amount received by any Person in connection with
                  such purchase, redemption, acquisition, cancellation or other

                  retirement of such shares that is concurrently used to repay
                  loans made to such Person by the Company pursuant to clause
                  (f) of the definition of "Permitted Investment");

                           (vii)    payment to the Equity Sponsors in an annual
                  amount not to exceed $500,000 as consideration for management
                  consulting or financial advisory services provided to the
                  Company or any of the Subsidiaries;

                           (viii)   the repurchase of Capital Stock deemed to
                  occur upon the exercise of stock options to the extent such
                  Capital Stock represents a portion of the exercise price of
                  those stock options;

                           (ix)     the declaration and payment of regularly
                  scheduled or accrued dividends to holders of any class or
                  series of Disqualified Stock of the Company or any Restricted
                  Subsidiary of the Company or to holders of any class of
                  preferred stock of any Restricted Subsidiary, in each case
                  issued on or after the Closing Date in accordance with the
                  covenant described in Section 4.09; and

                           (x)      other Restricted Payments not to exceed $5
                  million during the life of this Indenture.

                  The actions described in clauses (v) and (vi) of Section
4.07(b) will be Restricted Payments that will be permitted to be taken in
accordance with this Section 4.07 but will reduce the amount that would
otherwise be available for Restricted Payments under clause (iv)(C) of Section
4.07(a) hereof and the actions described in clauses (i), (ii), (iii), (iv),
(vii), (viii), (ix) and (x) of Section 4.07(b) will be Restricted Payments that
will be permitted to be taken in accordance with this Section 4.07 and will not
reduce the amount that would otherwise be available for Restricted Payments
under clause (iv)(C) of Section 4.07(a) hereof.

                  For the purpose of making any calculations under this
Indenture (i) if a Restricted Subsidiary is designated an Unrestricted
Subsidiary, the Company will be deemed to have made an Investment in an amount
equal to the greater of the fair market value or net book value of the net
assets of such Restricted Subsidiary at the time of such designation as
determined by the Board, and (ii) any property transferred to or from an
Unrestricted Subsidiary will be valued at fair market value at the time of such
transfer, as determined by the Board. The amount of all Restricted Payments
(other than cash) shall be the fair market value on the date of the Restricted
Payment of the asset(s) or securities proposed to be transferred or issued by
the Company or such Restricted Subsidiary, as the case may be, pursuant to the
Restricted Payment. The fair market value of any noncash Restricted Payment
shall be determined by the Board whose resolution with respect thereto shall be
delivered to the Trustee, such determination to be based upon an opinion or
appraisal issued by an accounting, appraisal or investment banking firm of
national standing if such fair market value exceeds $10 million. Not later than
the date of making any Restricted Payment, the Company shall deliver to the
Trustee an Officers' Certificate stating that such Restricted Payment is
permitted and setting forth the basis upon which the calculations required under
this Section 4.07 were computed, together with a copy of any fairness opinion or
appraisal required by this Indenture.

                  If the aggregate amount of all Restricted Payments calculated
under the foregoing provision includes an Investment in an Unrestricted
Subsidiary or other Person that thereafter becomes a Restricted Subsidiary, the
aggregate amount of all Restricted Payments calculated under the foregoing
provision will be reduced by the lesser of (x) the greater of the fair market
value or net book value of such Subsidiary at the time it becomes a Restricted
Subsidiary and (y) the initial amount of such Investment.

                  If an Investment resulted in the making of a Restricted
Payment, the aggregate amount of all Restricted Payments calculated under the
foregoing provision will be reduced by the amount of any net reduction in such
Investment (resulting from the payment of interest or dividends, loan repayment,
transfer of assets or otherwise), to the extent such net reduction is not
included in the Company's Consolidated Net Income; provided that the total
amount by which the aggregate amount of all Restricted Payments may be reduced
may not exceed the lesser of (x) the cash proceeds received by the Company and
its Restricted Subsidiaries in connection with such net reduction and (y) the
initial amount of such Investment.

                  In computing the Consolidated Net Income of the Company for
purposes of Section 4.07(a)(iv)(C)(1) hereof, (i) the Company may use audited
financial statements for the portions of the relevant period for which audited
financial statements are available on the date of determination and unaudited
financial statements and other current financial data based on the books and
records of the Company for the remaining portion of such period and (ii) the
Company will be permitted to rely in good faith on the financial statements and
other financial data derived from its books and records that are available on
the date of determination. If the Company makes a Restricted Payment that, at
the time of the making of such Restricted Payment, would in the good faith
determination of the Company be permitted under the requirements of this
Indenture, such Restricted Payment will be deemed to have been made in
compliance with this Indenture notwithstanding any subsequent adjustments made
in good faith to the Company's financial statements affecting Consolidated Net
Income of the Company for any period.

Section 4.08. Dividends and Other Payment Restrictions Affecting Restricted
Subsidiaries.

                  (a)      The Company will not, and will not permit any
Restricted Subsidiary to, directly or indirectly, create or otherwise cause or
suffer to exist or become effective any consensual encumbrance or restriction of
any kind on the ability of any Restricted Subsidiary to (i) pay dividends, in
cash or otherwise, or make any other distributions on or in respect of its
Capital Stock to the Company or any of its Restricted Subsidiaries; (ii) pay any
Indebtedness owed to the Company or any other Restricted Subsidiary; (iii) make
loans or advances to, or any Investment in, the Company or any other Restricted
Subsidiary; or (iv) transfer any of its properties or assets to the Company or
any other Restricted Subsidiary.

                  (b)      However, the preceding restrictions will not apply to
encumbrances or restrictions existing under or by reason of:

                           (i)      any agreement (including the Credit
                  Agreement) in effect on the Closing Date;

                                     - 55 -
<PAGE>

                           (ii)     customary non-assignment provisions of any
                  lease, license or other contract entered into in the ordinary
                  course of business by the Company or any Restricted
                  Subsidiary;

                           (iii)    the refinancing or successive refinancing of
                  Indebtedness incurred under any of the agreements in effect on
                  the Closing Date (including the Credit Agreement), so long as
                  such encumbrances or restrictions are no more restrictive,
                  taken as a whole, than those contained in such original
                  agreement;

                           (iv)     any agreement or other instrument of a
                  Person acquired by the Company or any Restricted Subsidiary in
                  existence at the time of such acquisition (but not created in
                  contemplation thereof), which encumbrance or restriction is
                  not applicable to any Person, or the properties or assets of
                  any Person, other than the Person, or the property or assets
                  of the Person, so acquired;

                           (v)      Capitalized Lease Obligations and purchase
                  money obligations for acquired property permitted under
                  Section 4.09 hereof that impose restrictions of the nature
                  described in clause (iv) of Section 4.08(a) hereof on the
                  property so acquired;

                           (vi)     any agreement for the sale of a Restricted
                  Subsidiary or an asset that restricts distributions by that
                  Restricted Subsidiary or transfers of such asset pending its
                  sale;

                           (vii)    secured Indebtedness otherwise permitted to
                  be incurred pursuant to Section 4.12 hereof that limits the
                  right of the debtor to dispose of the assets securing such
                  Indebtedness;

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

                           (ix)     Non-Recourse Indebtedness of any Permitted
                  Joint Venture permitted to be incurred under this Indenture;

                           (x)      applicable law or regulation;

                           (xi)     a Receivables Program with respect to a
                  Receivables Subsidiary; and

                           (xii)    customary provisions in joint venture,
                  limited liability company, operating, partnership, shareholder
                  and other similar agreements entered into in the ordinary
                  course of business by the Company or any Restricted
                  Subsidiary.

Section 4.09. Incurrence of Indebtedness and Issuance of Disqualified Stock.

                  (a)      The Company will not, and will not permit any
Restricted Subsidiary to, create, issue, assume, guarantee or in any manner
become directly or indirectly liable for the payment of, or otherwise incur
(collectively, "incur"), any Indebtedness (including Acquired

                                     - 56 -
<PAGE>

Indebtedness and the issuance of Disqualified Stock), except that the Company
and any Guarantors may incur Indebtedness if, at the time of such event, the
Fixed Charge Coverage Ratio for the immediately preceding four full fiscal
quarters for which internal financial statements are available, taken as one
accounting period, would have been equal to at least 2.0 to 1.0.

                  (b)      In making the foregoing calculation, pro forma effect
will be given to: (i) the incurrence of such Indebtedness and (if applicable)
the application of the net proceeds therefrom, including to refinance other
Indebtedness, as if such Indebtedness was incurred and the application of such
proceeds occurred at the beginning of such four-quarter period; (ii) the
incurrence, repayment or retirement of any other Indebtedness by the Company or
its Restricted Subsidiaries since the first day of such four-quarter period as
if such Indebtedness was incurred, repaid or retired at the beginning of such
four-quarter period; and (iii) the acquisition (whether by purchase, merger or
otherwise) or disposition (whether by sale, merger or otherwise) of any company,
entity or business acquired or disposed of by the Company or its Restricted
Subsidiaries, as the case may be, since the first day of such four-quarter
period, as if such acquisition or disposition occurred at the beginning of such
four-quarter period; provided that, in the case of clause (iii), such
adjustments in connection with any acquisition of any company, entity or
business will be based on the financial statements or other information of the
company, business or entity acquired, if available, as adjusted in the good
faith judgment of the chief financial or accounting officer of the Company and
set forth in an officers' certificate delivered to the Trustee to reflect the
revenue per patient, cost and operating structure of the Company for similar
assets or businesses consistent with past practice. In making a computation
under the foregoing clause (i) or (ii), (A) the amount of Indebtedness under a
revolving credit facility will be computed based on the average daily balance of
such Indebtedness during such four-quarter period, (B) if such Indebtedness
bears, at the option of the Company, a fixed or floating rate of interest,
interest thereon will be computed by applying, at the option of the Company,
either the fixed or floating rate, and (C) the amount of any Indebtedness that
bears interest at a floating rate will be calculated as if the rate in effect on
the date of determination had been the applicable rate for the entire period
(taking into account any Hedging Obligations applicable to such Indebtedness if
such Hedging Obligations have a remaining term at the date of determination in
excess of 12 months).

                  (c)      Notwithstanding the foregoing, the Company may, and
may permit its Restricted Subsidiaries to, incur the following Indebtedness
("Permitted Indebtedness"):

                           (i)      Indebtedness of the Company or any Guarantor
                  under a Credit Facility (and the incurrence by any Guarantor
                  of guarantees thereof) in an aggregate principal amount at any
                  one time outstanding not to exceed $125 million;

                           (ii)     Indebtedness represented by the Initial
                  Notes (other than the Additional Notes) and the Guarantees and
                  the Exchange Notes and related guarantees issued in respect of
                  the Initial Notes;

                           (iii)    Existing Indebtedness not otherwise referred
                  to in this definition of "Permitted Indebtedness";

                                     - 57 -
<PAGE>

                           (iv)     the incurrence by the Company of Permitted
                  Refinancing Indebtedness in exchange for, or the net cash
                  proceeds of which are used to refund, refinance or replace,
                  any Indebtedness that is permitted to be incurred under clause
                  (ii) or (iii) above;

                           (v)      Indebtedness owed by the Company to any
                  Restricted Subsidiary or owed by any Restricted Subsidiary to
                  the Company or a Restricted Subsidiary (provided that such
                  Indebtedness is held by the Company or such Restricted
                  Subsidiary); provided, however, that:

                                    (A)      any Indebtedness of the Company or
                           any Guarantor owing to any such Restricted Subsidiary
                           is unsecured and subordinated in right of payment
                           from and after such time as the Notes shall become
                           due and payable (whether at Stated Maturity,
                           acceleration, or otherwise) to the payment and
                           performance of the Company's obligations under the
                           Notes or the Guarantor's obligations under its
                           Guarantee, as the case may be; and

                                    (B)      (x) any subsequent issuance or
                           transfer of Equity Interests that results in any such
                           Indebtedness being held by a Person other than the
                           Company or a Restricted Subsidiary thereof and (y)
                           any sale or other transfer of any such Indebtedness
                           to a Person that is not either the Company or a
                           Restricted Subsidiary thereof, shall be deemed, in
                           each case, to constitute an incurrence of such
                           Indebtedness by the Company or such Restricted
                           Subsidiary, as the case may be, that was not
                           permitted by this clause (v);

                           (vi)     Indebtedness of the Company or any
                  Restricted Subsidiary under Hedging Obligations incurred not
                  for speculative purposes;

                           (vii)    Indebtedness of the Company or any
                  Restricted Subsidiary consisting of guarantees, earn-outs,
                  indemnities or obligations in respect of purchase price
                  adjustments in connection with the acquisition or disposition
                  of assets, including, without limitation, shares of Capital
                  Stock;

                           (viii)   Guarantees by any Restricted Subsidiary made
                  in accordance with the provisions of Sections 4.19 or 4.20
                  hereof;

                           (ix)     Indebtedness arising from the honoring by a
                  bank or other financial institution of a check, draft or
                  similar instrument inadvertently (except in the case of
                  daylight overdrafts) drawn against insufficient funds in the
                  ordinary course of business; provided, however, that such
                  Indebtedness is extinguished within five business days of
                  incurrence;

                           (x)      Indebtedness of the Company or any of its
                  Restricted Subsidiaries represented by letters of credit for
                  the account of the Company or such Restricted Subsidiary, as
                  the case may be, in order to provide security for workers'
                  compensation claims, payment obligations in connection with
                  self-insurance or

                                     - 58 -

                  similar requirements in the ordinary course of business;
                  provided that, in each case contemplated by this clause (x),
                  upon the drawing of such letters of credit or other
                  instrument, such obligations are reimbursed within 30 days
                  following such drawing;

                           (xi)     the incurrence of Non-Recourse Indebtedness
                  by Permitted Joint Ventures that are Restricted Subsidiaries;

                           (xii)    obligations in respect of performance, bid
                  and surety bonds and completion guarantees provided by the
                  Company or any Restricted Subsidiary in the ordinary course of
                  business; and

                           (xiii)   Indebtedness of the Company or any
                  Restricted Subsidiary not permitted by any other clause of
                  this definition, in an aggregate principal amount in each case
                  calculated as of the time such Indebtedness is incurred, not
                  to exceed at any one time outstanding the Consolidated EBITDA
                  for the immediately preceding four full fiscal quarters for
                  which internal financial statements are available, taken as
                  one accounting period.

                  (d)      For purposes of determining compliance with this
Section 4.09, in the event that any proposed Indebtedness meets the criteria of
more than one of the categories of Permitted Indebtedness described in clauses
(i) through (xiii) above, or is entitled to be incurred pursuant to Section
4.09(a) hereof, the Company will be permitted to classify all or a portion of
such item of Indebtedness on the date of its incurrence, or later reclassify all
or a portion of such item of Indebtedness, in any manner that complies with this
Section 4.09. Indebtedness under the Credit Agreement incurred on the Closing
Date shall be deemed to have been incurred on the Closing Date in reliance on
the exception provided by clause (i) of the definition of Permitted
Indebtedness.

                  Accrual of interest, accrual of dividends, accretion or
amortization of original issue discount or other value and the payment of
interest on any Indebtedness in the form of additional Indebtedness, and the
payment of dividends on any Disqualified Stock or Preferred Stock in the form of
additional shares of Disqualified Stock or Preferred Stock will not be deemed to
be an incurrence of Indebtedness for purposes of this covenant; provided, in
each such case, that the amount thereof as accrued is included in the Fixed
Charge Coverage Ratio.

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

Section 4.10. Asset Sales.

                  (a)      The Company will not, and will not permit any
Restricted Subsidiary to, engage in any Asset Sale unless (i) the consideration
received by the Company or such Restricted Subsidiary for such Asset Sale is not
less than the fair market value of the assets sold as evidenced by a resolution
of the board of directors of such entity set forth in an Officers' Certificate
delivered to the Trustee; and (ii) the consideration received by the Company or
the relevant Restricted Subsidiary in respect of such Asset Sale consists of at
least 75% cash or Cash Equivalents. For purposes of this clause (ii), cash and
Cash Equivalents includes (1) any

                                     - 59 -
<PAGE>

liabilities (as reflected in the Company's consolidated balance sheet) of the
Company or any Restricted Subsidiary (other than contingent liabilities and
liabilities that are by their terms subordinated to the Notes or any Note
Guarantee) that are assumed by any transferee of any such assets or other
property in such Asset Sale, and where the Company or the relevant Restricted
Subsidiary is released from any further liability in connection therewith with
respect to such liabilities, (2) any securities, notes or other similar
obligations received by the Company or any such Restricted Subsidiary from such
transferee that are converted within 180 days of the related Asset Sale by the
Company or such Restricted Subsidiary into cash or Cash Equivalents (to the
extent of the net cash proceeds or the Cash Equivalents (net of related costs)
received upon such conversion); and (3) any Designated Noncash Consideration
received by the Company or any such Restricted Subsidiary in the Asset Sale
having an aggregate fair market value, as determined by the Board, taken
together with all other Designated Noncash Consideration received pursuant to
this clause that is at that time outstanding, not to exceed the greater of:

                           (A)      $7.5 million; and

                           (B)      10% of Consolidated Tangible Assets at the
                  time of the receipt of such Designated Noncash Consideration
                  (with the fair market value of each item of such Designated
                  Noncash Consideration being measured at the time received and
                  without giving effect to subsequent changes in value).

                  (b)      If the Company or any Restricted Subsidiary engages
in an Asset Sale, the Company may, at its option, within 12 months after such
Asset Sale, (i) apply all or a portion of the Net Cash Proceeds to the permanent
reduction of amounts outstanding under the Credit Agreement (and to
correspondingly reduce the commitments, if any, with respect thereto) or to the
repayment of other Senior Indebtedness of the Company or a Restricted
Subsidiary, provided that the repayment of any Indebtedness incurred under the
Credit Agreement with the proceeds of any Sale and Leaseback Transaction shall
not be required to result in the permanent reduction of the amounts outstanding
under the Credit Agreement or correspondingly permanently reduce the commitments
thereunder so long as the Company would at such time after giving effect thereto
be permitted to incur at least $1.00 of additional Indebtedness pursuant to the
Fixed Charge Coverage Test set forth in Section 4.09(a) hereof, or (ii) invest
(or enter into a legally binding agreement to invest) all or a portion of such
Net Cash Proceeds in properties and assets to 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, as the
case may be, existing on the Closing Date or in businesses the same, similar or
reasonably related thereto. If any such legally binding agreement to invest such
Net Cash Proceeds is terminated, the Company may, within 90 days of such
termination or within 12 months of such Asset Sale, whichever is later, invest
such Net Cash Proceeds as provided in clause (i) or (ii) (without regard to the
parenthetical contained in such clause (ii)) above. Pending the final
application of any such Net Cash Proceeds, the Company may temporarily reduce
revolving credit borrowings or otherwise invest such Net Cash Proceeds in a
manner that is not prohibited by this Indenture. The amount of such Net Cash
Proceeds not so used as set forth above in this paragraph shall constitute
"Excess Proceeds".

                  (c)      When the aggregate amount of Excess Proceeds exceeds
$10 million, the Company will, within 30 days thereafter, make an offer to
purchase (an "Excess Proceeds

                                     - 60 -
<PAGE>

Offer") from all Holders of Notes and any other Pari Passu Indebtedness of the
Company (to the extent the terms of such Pari Passu Indebtedness so require) on
a pro rata basis, in accordance with applicable procedures set forth in Section
3.09 of this Indenture, the maximum principal amount (expressed as a multiple of
$1,000) of Notes and Pari Passu Indebtedness that may be purchased with the
Excess Proceeds, at a purchase price in cash equal to 100% of the principal
amount thereof, plus accrued interest, if any, to the date such offer to
purchase is consummated. To the extent that the aggregate principal amount of
Notes and Pari Passu Indebtedness tendered pursuant to such offer to purchase is
less than the Excess Proceeds, the Company may use such deficiency for general
corporate purposes not prohibited under this Indenture. If the aggregate
principal amount of Notes and Pari Passu Indebtedness validly tendered and not
withdrawn by Holders thereof exceeds the Excess Proceeds, the Notes and Pari
Passu Indebtedness to be purchased will be selected on a pro rata basis. Upon
completion of such offer to purchase, the amount of Excess Proceeds will be
reset to zero.

                  (d)      The Company shall 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 Excess Proceeds
Offer. To the extent that the provisions of any securities laws or regulations
conflict with the "Asset Sales" provisions of this Indenture, the Company shall
comply with the applicable securities laws and regulations and shall not be
deemed to have breached its obligations under the "Asset Sales" provisions of
this Indenture by virtue thereof.

Section 4.11. Transactions with Affiliates.

                  (a)      The Company will not, and will not permit any
Restricted Subsidiary to, directly or indirectly, enter into or suffer to exist
any transaction with, or for the benefit of, any Affiliate of the Company
("Interested Persons"), unless (i) such transaction is on terms that are no less
favorable to the Company or such Restricted Subsidiary, as the case may be, than
those that could have been obtained in an arm's-length transaction with third
parties who are not Interested Persons and (ii) the Company delivers to the
Trustee (x) with respect to any transaction or series of related transactions
entered into after the Closing Date involving aggregate payments in excess of $5
million, a resolution of the Board set forth in an officers' certificate
certifying that such transaction or transactions complies with clause (i) above
and that such transaction or transactions have been approved by the Board
(including a majority of the Disinterested Directors) and (y) with respect to a
transaction or series of related transactions involving aggregate payments equal
to or greater than $15 million, a written opinion as to the fairness to the
Company or such Restricted Subsidiary of such transaction or series of
transactions from a financial point of view issued by an accounting, appraisal
or investment banking firm, in each case of national standing.

                  (b)      The foregoing Section 4.11(a) will not restrict:

                           (i)      transactions among the Company and/or its
                  Restricted Subsidiaries;

                           (ii)     the Company from paying reasonable and
                  customary regular compensation, including under any stock
                  option or stock incentive plans,

                                     - 61 -
<PAGE>

                  indemnification, reimbursement and fees to officers of the
                  Company or any Restricted Subsidiary and to directors of the
                  Company or any Restricted Subsidiary who are not employees of
                  the Company or any Restricted Subsidiary;

                           (iii)    transactions permitted by Section 4.07
                  hereof;

                           (iv)     advances to employees for moving,
                  entertainment and travel expenses and similar expenditures in
                  the ordinary course of business and consistent with past
                  practice;

                           (v)      any Receivables Program of the Company or a
                  Restricted Subsidiary;

                           (vi)     the agreements as in effect as of the
                  Closing Date or any amendment thereto (so long as the amended
                  agreement, taken as a whole, is not more disadvantageous to
                  the Holders in any material respect than such agreement
                  immediately prior to such amendment) or any transaction
                  contemplated thereby; and

                           (vii)    sales of Equity Interests; and

                           (viii)   loans and advances permitted by clause
                  (f)(ii) of the definition of "Permitted Investments".

Section 4.12. Liens.

                  (a)      The Company will not, and will not permit any
Restricted Subsidiary to, directly or indirectly, create, incur, assume or
suffer to exist any Lien securing Pari Passu Indebtedness or Subordinated
Indebtedness of the Company on or with respect to any of its property or assets,
including any shares of stock or Indebtedness of any Restricted Subsidiary,
whether owned at the Closing Date or thereafter acquired, or any income, profits
or proceeds therefrom, or assign or otherwise convey any right to receive income
thereon, unless:

                           (i)      in the case of any Lien securing
                  Subordinated Indebtedness, the Notes are secured by a Lien on
                  such property, assets or proceeds that is senior in priority
                  to such Lien; and

                           (ii)     in the case of any Lien securing Pari Passu
                  Indebtedness, the Notes are secured by a Lien on such
                  property, assets or proceeds that is senior in priority to or
                  ranks equally with such Lien.

                  (b)      The Company will not permit any Guarantor to,
directly or indirectly, create, incur, assume or suffer to exist any Lien
securing Pari Passu Indebtedness or Subordinated Indebtedness of such Guarantor
on or with respect to such Guarantor's properties or assets, including any
shares of stock or Indebtedness of any other Restricted Subsidiary owned by such
Guarantor, whether owned at the Closing Date or thereafter acquired, or any
income, profits or proceeds therefrom, or assign or otherwise convey any right
to receive income thereon, unless:

                                     - 62 -
<PAGE>

                           (i)      in the case of any Lien securing Pari Passu
                  Indebtedness of such Guarantor, each Guarantee of such
                  Guarantor is secured by a Lien on such property, assets or
                  proceeds that is senior in priority to or ranks equally with
                  such Lien; and

                           (ii)     in the case of any Lien securing
                  Subordinated Indebtedness of such Guarantor, each Guarantee of
                  such Guarantor is secured by a Lien on such property, assets
                  or proceeds that is senior in priority to such Lien.

                  (c)      Notwithstanding the foregoing, any Lien securing the
Notes required to be granted pursuant to this covenant shall be automatically
and unconditionally released and discharged upon the release by the holders of
the applicable Pari Passu Indebtedness or Subordinated Indebtedness of their
Lien on the property or assets of the Company or any Restricted Subsidiary or
Guarantor (including any deemed release upon payment in full of all obligations
under such Indebtedness), at such time as the holders of such Pari Passu
Indebtedness or Subordinated Indebtedness also release their Lien on the
property or assets of the Company or such Restricted Subsidiary or such
Guarantor, or upon any sale, exchange or transfer to any Person not an Affiliate
of the Company of the property or assets secured by such Lien, or of all of the
Capital Stock held by the Company or any Restricted Subsidiary or any Guarantor
in, or all or substantially all the assets of, any Restricted Subsidiary
creating such Lien.

Section 4.13. Corporate Existence.

                  Subject to Article Five, the Company will do or cause to be
done all things necessary to preserve and keep in full force and effect the
corporate existence, rights (charter and statutory) and franchises of the
Company and each Restricted Subsidiary; provided that the Company shall not be
required to preserve any such right or franchise if the Board shall determine
that the preservation thereof is no longer desirable in the conduct of the
business of the Company and its Restricted Subsidiaries as a whole and that the
loss thereof is not disadvantageous in any material respect to the Holders.

Section 4.14. Limitation on Layering Debt.

                  Neither the Company nor any Guarantor will incur, create,
issue, assume, guarantee or otherwise become liable for any Indebtedness or
guarantee, as applicable, that is subordinate or junior in right of payment to
any Senior Indebtedness and senior in any respect in right of payment to the
Notes or such Guarantor's Guarantee, respectively.

(equal to $1,000 or an integral multiple thereof) of such Holder's Notes
pursuant to the offer described below (the "Change of Control Offer") at an
offer price in cash equal to 101% of the aggregate principal amount thereof plus

                  Act (the "Change of Control Payment Date");

                           (iii)    that any Note not tendered will continue to
                  accrue interest;

                           (iv)     that, unless the Company defaults in the
                  payment of the Change of Control Payment, all Notes accepted
                  for payment pursuant to the Change of Control Offer shall
                  cease to accrue interest after the Change of Control Payment
                  Date;

                           (v)      that Holders electing to have any Notes

                  their election if the Paying Agent receives, not later than
                  the close of business on the second Business Day preceding the
                  Change of Control Payment Date, a telegram, telex, facsimile
                  transmission or letter setting forth the name of the Holder,

                  the Notes purchased; and;

                           (vii)    that Holders whose Notes are being purchased
                  only in part will be issued new Notes equal in principal
                  amount to the unpurchased portion of the Notes surrendered,
                  which unpurchased portion must be equal to $1,000 in principal
                  amount or an integral multiple thereof.

                  (c)      By 2:00 p.m. Eastern Time on the Change of Control

a new Note equal in principal amount to any unpurchased portion of the Notes
surrendered, if any; provided that each such new Note shall be in a principal
amount of $1,000 or an integral multiple thereof.

                  (d)      Notwithstanding anything to the contrary in this
Section 4.15, the Company shall 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 forth in this Section 4.15 and all other provisions of this

Section 4.16. Limitation on Issuances and Sales of Capital Stock of Restricted
Subsidiaries.

                  The Company (a) will not permit any Restricted Subsidiary to

thereto, and (b) will not, and will not permit any Restricted Subsidiary to,
transfer, convey, sell, lease or otherwise dispose of any Capital Stock of any

(i) the sale or other disposition of all, but not less than all, of the issued
and outstanding Capital Stock of a Restricted Subsidiary owned by the Company
and its Restricted Subsidiaries in compliance with the other provisions of this
Indenture, (ii) the sale or other disposition of a portion of the issued and
outstanding Capital Stock of a Restricted Subsidiary, whether or not as a result
of such sale or disposition such Restricted Subsidiary continues or ceases to be
a Restricted Subsidiary, if (A) such sale or disposition is of a portion of the
issued and outstanding Capital Stock of a Guarantor, such Guarantor continues to
guarantee the Notes, and (B) such sale or disposition is permitted under, and
the Company or such Restricted Subsidiary applies the Net Cash Proceeds of any
such sale in accordance with, Section 4.10 hereof, or (iii) the ownership by

                  (a)      The Board may designate any Subsidiary (including any
newly acquired or newly formed Subsidiary) to be an Unrestricted Subsidiary so
long as (i) such Subsidiary has no Indebtedness other than Non-Recourse
Indebtedness, except that such Subsidiary may Guarantee the Notes, (ii) no
default with respect to any Indebtedness of such Subsidiary would permit (upon
notice, lapse of time or otherwise) any holder of any other Indebtedness of the
Company or any

                                     - 65 -
<PAGE>

Restricted Subsidiary to declare a default on such other Indebtedness or cause
the payment thereof to be accelerated or payable prior to its stated maturity,
(iii) any Investment in such Subsidiary made as a result of designating such
Subsidiary an Unrestricted Subsidiary will not violate the provisions of Section
4.07 hereof, (iv) neither the Company nor any Restricted Subsidiary has a
contract, agreement, arrangement, understanding or obligation of any kind,
whether written or oral, with such Subsidiary other than those that might be
obtained at the time from Persons who are not Affiliates of the Company, and (v)
neither the Company nor any Restricted Subsidiary has any obligation to
subscribe for additional shares of Capital Stock or other equity interests in

condition or to cause such Subsidiary to achieve certain levels of operating
results.

                  (b)      The Board may designate any Unrestricted Subsidiary
as a Restricted Subsidiary; provided that (i) no Default or Event of Default has
occurred and is continuing following such designation and (ii) the Company
would, at the time of making such designation and giving such pro forma effect
as if such designation had been made at the beginning of the applicable four
quarter period, have been permitted to incur at least $1.00 of additional
Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in
Section 4.09(a) hereof (treating any Indebtedness of such Unrestricted
Subsidiary as the incurrence of Indebtedness by a Restricted Subsidiary).

Section 4.18. Payments for Consent.

                  Neither the Company nor any of its Restricted Subsidiaries
will, directly or indirectly, pay or cause to be paid any consideration, whether
by way of interest, fee or otherwise, to any Holder for or as an inducement to
any consent, waiver or amendment of any of the terms or provisions of this
Indenture or the Notes unless such consideration is offered to be paid or is
paid to all Holders that consent, waive or agree to amend in the time frame set
forth in the solicitation documents relating to such consent, waiver or
agreement.

Section 4.19. Guarantees of Indebtedness by Restricted Subsidiaries.

                  (a)      The Company will not permit any Restricted Subsidiary
that is not a Guarantor, directly or indirectly, to guarantee, assume or in any
other manner become liable for the payment of any Indebtedness of the Company or
any Indebtedness of any Guarantor or secure the payment of any Indebtedness of
the Company, including pledging any intercompany notes, unless (i) such
Restricted Subsidiary simultaneously executes and delivers a supplemental
indenture providing for a guarantee of payment of the Notes by such Restricted
Subsidiary on a senior subordinated basis on the same terms as set forth in this
Indenture and (ii) with respect to any guarantee of Subordinated Indebtedness by
a Restricted Subsidiary, any such guarantee is subordinated to such Restricted
Subsidiary's guarantee with respect to the Notes at least to the same extent as
such Subordinated Indebtedness is subordinated to the Notes, provided that the
foregoing provision will not be applicable to any guarantee by any Restricted
Subsidiary that existed at the time such Person became a Restricted Subsidiary
and was not incurred in connection with, or in contemplation of, such Person
becoming a Restricted Subsidiary.

                  (b)      Any guarantee by a Restricted Subsidiary of the Notes
pursuant to the preceding paragraph may provide by its terms that it will
automatically and unconditionally be

                                     - 66 -

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 and the Restricted
Subsidiaries' 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 (in any such case which transaction is not prohibited by
this Indenture) or (ii) the release by the holders of the Indebtedness described
in the prior paragraph of their security interest or their guarantee by such
Restricted Subsidiary, at such time as (A) no other Indebtedness described in
the prior paragraph 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,
except a discharge or release by or as a result of payment under such guarantee.

Section 4.20. Issuances of Guarantees by New Wholly Owned Restricted
Subsidiaries.

                  The Company will provide to the Trustee, within 30 days after
the date that any Person (other than a Foreign Subsidiary) becomes a Wholly
Owned Restricted Subsidiary, a supplemental indenture to this Indenture,
executed by such new Wholly Owned Restricted Subsidiary, providing for a full
and unconditional guarantee on a senior subordinated basis by such new Wholly
Owned Restricted Subsidiary of the Company's obligations under the Notes and
this Indenture to the same extent as that set forth in this Indenture.

Section 4.21. Lines of Business

                  Neither the Company nor any of its Restricted Subsidiaries
will directly or indirectly engage in any line or lines of business activity
other than that which is a Permitted Business.

Section 5.01. Merger, Consolidation or Sale of Assets.

                  (a)      The Company will not, in a single transaction or
series of related transactions, consolidate or merge with or into, or directly
and/or indirectly through its Subsidiaries, sell, assign, transfer, lease,
convey or otherwise dispose of all or substantially all of its properties or
assets (determined on a consolidated basis for the Company and its Subsidiaries,
taken as a whole) in one or more related transactions to, another corporation,
Person or entity unless:

                           (i)      either (x) the Company is the surviving
                  corporation or (y) the entity or the Person formed by or
                  surviving any such consolidation or merger (if other than the
                  Company) or to which such sale, assignment, transfer, lease,
                  conveyance or other disposition shall have been made (the
                  "Surviving Entity") is a corporation organized or existing
                  under the laws of the United States, any state thereof or the
                  District of Columbia and assumes all the obligations of the
                  Company under the Notes and this Indenture and the
                  Registration Rights Agreement, as the case may be, pursuant to
                  a supplemental indenture in a form

                                     - 67 -

                  reasonably satisfactory to the Trustee, and the Notes and this
                  Indenture and the Registration Rights Agreement will remain in
                  full force and effect as so supplemented (and any Guarantees
                  will be confirmed as applying to such Surviving Entity's
                  obligations);

                           (ii)     immediately after giving effect to such
                  transaction and treating any obligation of the Company in
                  connection with or as a result of such transaction as having
                  been incurred as of the time of such transaction, no Default
                  or Event of Default has occurred and is continuing;

                           (iii)    the Company (or the Surviving Entity if the
                  Company is not the continuing obligor under this Indenture)
                  could, at the time of such transaction and after giving pro
                  forma effect thereto as if such transaction had occurred at
                  the beginning of the applicable four-quarter period, incur at
                  least $1.00 of additional Indebtedness (other than Permitted
                  Indebtedness) pursuant Section 4.09(a) hereof;

                           (iv)     each Guarantor, unless it is the other party
                  to the transaction described above or the Company is the
                  continuing obligor under this Indenture, has by supplemental
                  indenture confirmed that its Guarantee applies to the
                  Surviving Entity's obligations under this Indenture and the
                  Notes;

                           (v)      if any of the property or assets of the
                  Company or any of its Restricted Subsidiaries would thereupon
                  become subject to any Lien, the provisions of Section 4.12
                  hereof are complied with; and

                           (vi)     the Company delivers or causes to be
                  delivered, to the Trustee, in form and substance reasonably
                  satisfactory to the Trustee, an Officers' Certificate and an
                  Opinion of Counsel, each stating that such transaction
                  complies with the requirements of this Indenture.

                  (b)      This Indenture will provide that no Guarantor may
consolidate with or merge with or into any other Person or convey, sell, assign,
transfer, lease or otherwise dispose of its properties and assets substantially
as an entirety to any other Person (other than the Company or another Guarantor)
unless:

                           (i)      subject to the provisions of the following
                  paragraph, the Person formed by or surviving such
                  consolidation or merger or to which such properties and assets
                  are transferred assumes all of the obligations of such
                  Guarantor under this Indenture and its Guarantee and the
                  Registration Rights Agreement, pursuant to a supplemental
                  indenture in form and substance reasonably satisfactory to the
                  Trustee, and such Guarantee, Indenture and Registration Rights
                  Agreement will remain in full force and effect;

                           (ii)     immediately after giving effect to such
                  transaction, no Default or Event of Default has occurred and
                  is continuing; and

                           (iii)    the Guarantor delivers, or causes to be
                  delivered, to the Trustee, in form and substance reasonably
                  satisfactory to the Trustee, an Officers' Certificate

                  complies with the requirements of this Indenture and that all
                  conditions precedent therein provided for relating to such
                  transaction have been complied with.

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

                  (c)      In the event of any transaction described in and
complying with the provisions of Section 5.01(a) hereof in which the Company is
not the continuing obligor under this Indenture, the Surviving Entity will
succeed to, and be substituted for, and may exercise every right and power of,
the Company under this Indenture, the Notes and the Registration Rights
Agreement, and thereafter the Company will, except in the case of a lease, be
discharged from all of its obligations and covenants under this Indenture, the
Notes and the Registration Rights Agreement.

                              DEFAULTS AND REMEDIES

Section 6.01. Events of Default and Remedies.

                  "Event of Default", wherever used herein, means any one of the
following events (whatever the reason for such Event of Default and whether it
shall be voluntary or involuntary or be effected by operation of law or pursuant
to any judgment, decree or order of any court or any order, rule or regulation
of any administrative or governmental body):

                  (a)      default in the payment of any interest on any Note
when it becomes due and payable, and continuance of such default for a period of
30 days (whether or not prohibited by Article Ten of this Indenture);

                  (b)      default in the payment of the principal of (or
premium, if any, on) the Notes when due whether at maturity, upon redemption, by
acceleration or otherwise (whether or not prohibited by Article Ten of this
Indenture);

                  (c)      failure to perform or comply with the provisions of
Sections 4.10, 4.15 and 5.01 hereof;

                  (d)      default in the performance, or breach, of any
covenant or agreement of the Company or any Guarantor contained in this
Indenture or in any Guarantee (other than a default in the performance, or
breach, of a covenant or agreement that is specifically dealt with elsewhere
herein), and continuance of such default or breach for a period of 60 days (or
30 days in the case of the failure to perform or comply with Sections 4.07 and
4.09 hereof) after written notice has been given to the Company by the Trustee
or to the Company and the Trustee by the Holders of at least 25% in aggregate
principal amount of the Notes then outstanding;

                                     - 69 -
<PAGE>

                  (e)      (x) an event of default has occurred under any
mortgage, bond, indenture, loan agreement or other document evidencing an issue
of Indebtedness of the Company or any Significant Subsidiary, which issue
individually or in the aggregate has an aggregate outstanding principal amount
of not less than $10 million, and such default has resulted in such Indebtedness
becoming, whether by declaration or otherwise, due and payable prior to the date
on which it would otherwise become due and payable or (y) a default in any
payment when due at final maturity of any such Indebtedness;

                  (f)      failure by the Company or any of its Significant
Subsidiaries to pay one or more final judgments the uninsured portion of which
exceeds in the aggregate $10 million, which judgment or judgments are not paid,
discharged or stayed for a period of 60 days;

                  (g)      any Guarantee ceases to be in full force and effect
or is declared null and void or any such Guarantor denies that it has any
further liability under any Guarantee, or gives notice to such effect (other
than by reason of the termination of this Indenture or the release of any such
Guarantee in accordance with this Indenture); or

                  (h)      the entry of a decree or order by a court having
jurisdiction in the premises adjudging the Company or any Significant Subsidiary
a bankrupt or insolvent, or approving as properly filed a petition seeking
reorganization, arrangement, adjustments or composition of or in respect of the
Company or any Significant Subsidiary under any Bankruptcy Law, or appointing a
receiver, liquidator, assignee, trustee, sequestrator (or other similar
official) of the Company or any Significant Subsidiary or of any substantial
part of its property, or ordering the winding up or liquidation of its affairs,
and the continuance of any such decree or order unstayed and in effect for a
period of 90 consecutive days; or

                  (i)      the institution by the Company or any Significant
Subsidiary of proceedings to be adjudicated a bankrupt or insolvent, or the
consent by it to the institution of bankruptcy or insolvency proceedings against
it, or the filing by it of a petition or answer or consent seeking
reorganization or relief under any Bankruptcy Law, or the consent by it to the
filing of any such petition or to the appointment of a receiver, liquidator,
assignee, trustee, sequestrator (or other similar official) of the Company, or
any Significant Subsidiary or of any substantial part of its property, or the
making by it of an assignment for the benefit of creditors, or the admission by
it in writing of its inability to pay its debts generally as they become due.

Section 6.02. Acceleration.

                  (a)      If an Event of Default (other than as specified in
Sections 6.01(h) or (i) hereof) occurs and is continuing, the Trustee or the
Holders of not less than 25% in aggregate principal amount of the Notes then
outstanding may, and the Trustee at the request of such Holders will, declare
the principal of, and accrued interest on, all of the outstanding Notes
immediately due and payable and, upon any such declaration, such principal and
such interest will become due and payable immediately. The Trustee shall
promptly notify the Company of any such acceleration of the Notes pursuant to
this Section 6.02(a).

                  In the case of any Event of Default occurring by reason of any
willful action or inaction taken or not taken by or on behalf of the Company
with the intention of

                                     - 70 -
<PAGE>

avoiding payment of the premium that the Company would have had to pay if the
Company had then elected to redeem the Notes pursuant to Article Three of this
Indenture, an equivalent premium shall also become immediately due and payable
to the extent permitted by law upon the acceleration of the Notes. If an Event
of Default occurs during any time that the Notes are outstanding, by reason of
any willful action or inaction taken or not taken by or on behalf of the Company
with the intention of avoiding the limitation on redemptions of Notes specified
in this Indenture, then the premium specified in paragraphs (a) or (b) of
Section 3.07 hereof, as applicable, shall also become immediately due and
payable to the extent permitted by law upon the acceleration of the Notes.

                  If an Event of Default specified in Sections 6.01(h) or (i)
hereof occurs and is continuing, then the principal of and accrued interest on
all of the outstanding Notes will ipso facto become and be immediately due and
payable without any declaration or other act on the part of the Trustee or any
Holder.

                  (b)      At any time after a declaration of acceleration under
this Indenture, but before a judgment or decree for payment of the money due has
been obtained by the Trustee, the Holders of a majority in aggregate principal
amount of the outstanding Notes, by written notice to the Company and the
Trustee, may rescind such declaration and its consequences if: (i) the Company
has paid or deposited with the Trustee a sum sufficient to pay (A) all overdue
interest on all Notes, (B) all unpaid principal of (and premium, if any, on) any
outstanding Notes that has become due otherwise than by such declaration of
acceleration and interest thereon at the rate borne by the Notes, (C) to the
extent that payment of such interest is lawful, interest upon overdue interest
and overdue principal at the rate borne by the Notes and (D) 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; and
(ii) all Events of Default, other than the non-payment of amounts of principal
of (or premium, if any, on), interest on the Notes that have become due solely
by such declaration of acceleration, have been cured or waived. No such
rescission will affect any subsequent default or impair any right consequent
thereon.

                  (c)      Notwithstanding the preceding paragraph, in the event
of a declaration of acceleration in respect of the Notes because an Event of
Default specified in Section 6.01(e) shall have occurred and be continuing and
provided no judgment or decree for payment of the money due has been obtained by
the Trustee, such declaration of acceleration shall be automatically annulled if
the Indebtedness that is the subject of such Event of Default has been
discharged or the holders thereof have rescinded their declaration of
acceleration in respect of such Indebtedness, and written notice of such
discharge or rescission, as the case may be, shall have been given to the
Trustee by the Company and countersigned by the holders of such Indebtedness or
a trustee, fiduciary or agent for such holders, within 30 days after such
declaration of acceleration in respect of the Notes, and no other Event of
Default has occurred during such 30-day period which has not been cured or
waived during such period.

                                     - 71 -

Section 6.03. Other Remedies.

                  (a)      If an Event of Default occurs and is continuing, the
Trustee may pursue any available remedy to collect the payment of principal,
premium, if any, or interest on the Notes or to enforce the performance of any
provision of the Notes or this Indenture.

                  (b)      The Trustee may maintain a proceeding even if it does
not possess any of the Notes or does not produce any of them in the proceeding.
A delay or omission by the Trustee or any Holder of a Note in exercising any
right or remedy accruing upon and during the continuance of an Event of Default
shall not impair the right or remedy or constitute a waiver of or acquiescence
in the Event of Default. All remedies are cumulative to the extent permitted by
law.

Section 6.04. Waiver of Past Defaults.

                  Holders of a majority in principal amount of the then
outstanding Notes by notice to the Trustee, may on behalf of the Holders of all
of the Notes, waive an existing Default or Event of Default and its consequences
hereunder, except (a) a continuing Default or Event of Default in the payment of
interest on, or the principal of, the Notes (which may only be waived with the
consent of each Holder of Notes effected), or (b) a Default or Event of 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 Note affected
by such modification or amendment (provided, however, that the Holders of a
majority in principal amount of the then outstanding Notes may rescind an
acceleration and its consequences, including any related payment default that
resulted from such acceleration). The Company shall deliver to the Trustee an
Officers' Certificate stating that the requisite percentage of Holders have
consented to such waiver and attaching copies of such consents. In case of any
such waiver, the Company, the Trustee and the Holders shall be restored to their
former positions and rights hereunder and under the Notes, respectively. This
Section 6.04 shall be in lieu of Section 316(a)(1)(B) of the TIA and such
Section 316(a)(1)(B) of the TIA is hereby expressly excluded from this Indenture
and the Notes, as permitted by the TIA. 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 6.05. Control by Majority.

                  Holders of a majority in principal amount of the then
outstanding Notes may direct the time, method and place of conducting any
proceeding for exercising any remedy available to the Trustee or exercising any
trust or power conferred on it. However, the Trustee may refuse to follow any
direction that conflicts with law or this Indenture that the Trustee determines
may be unduly prejudicial to the rights of other Holders of Notes or that may
involve the Trustee in personal liability. The Trustee may withhold from Holders
of the Notes notice of any continuing Default or Event of Default (except a
Default or Event of Default relating to the payment of principal or interest) if
it determines that withholding notice is in their interest.

Section 6.06. Limitation on Suits.

                  (a)      A Holder may pursue a remedy with respect to this
Indenture, or the Notes or the Guarantees only if:

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

                           (ii)     the Holders of at least 25% in principal
                  amount of the then outstanding Notes make a written request to
                  the Trustee to pursue the remedy;

                           (iii)    such Holder of a Note or Holders of Notes
                  offer and, if requested, provide to the Trustee security and
                  indemnity satisfactory to the Trustee against any loss,
                  liability or expense that might be incurred by it in
                  connection with the request or direction;

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

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

                  (b)      A Holder of a Note may not use this Indenture to
prejudice the rights of another Holder of a Note or to obtain a preference or
priority over another Holder of a Note.

Section 6.07. Rights of Holders of Notes to Receive Payment.

                  Notwithstanding any other provision of this Indenture, the
right of any Holder of a Note to receive payment of principal, premium, if any,
interest on the Note, on or after the respective due dates expressed in the Note
(including in connection with an offer to purchase), or to bring suit for the
enforcement of any such payment on or after such respective dates, shall not be
impaired or affected without the consent of such Holder.

Section 6.08. Collection Suit by Trustee.

                  If an Event of Default specified in Section 6.01(a) or (b)
occurs and is continuing, the Trustee is authorized to recover judgment in its

amount of principal of, premium, if any, interest remaining unpaid on the Notes

Section 6.09. Trustee May File Proofs of Claim.

                  The Trustee is authorized to file such proofs of claim and
other papers or documents as may be necessary or advisable in order to have the
claims of the Trustee (including any claim for the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel) and
the Holders of the Notes allowed in any judicial proceedings relative to the
Company or any Guarantor (or any other obligor upon the Notes), its creditors or
its property and shall be entitled and empowered to collect, receive and
distribute any money or other securities or property payable or deliverable on
any such claims and any custodian in any such judicial proceeding is hereby
authorized by each Holder to make such payments to the Trustee, and in the event
that the Trustee shall consent to the making of such payments directly to the
Holders, to pay to the Trustee any amount due to it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To
the extent that the payment of any such compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel, and any other amounts due

on, and shall be paid out of, any and all distributions, dividends, money,
securities and other properties that the Holders may be entitled to receive in
such proceeding whether in liquidation or under any plan of reorganization or
arrangement or otherwise. 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 Notes or the rights of any Holder, or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding.

due under Section 7.07 hereof, including payment of all compensation, expense
and liabilities incurred, and all advances made, by the Trustee and the costs
and expenses of collection;

                  Second: to Holders of Notes for amounts due and unpaid on the
Notes for principal, premium, if any, interest ratably, without preference or
priority of any kind, according to the amounts due and payable on the Notes for

any party litigant in the suit of an undertaking to pay the costs of the suit,
and the court in its discretion may assess reasonable costs, including
reasonable attorneys' fees, against any party litigant in the suit, having due

                                     TRUSTEE

Section 7.01. Duties of Trustee.

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

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

                           (i)      the duties of the Trustee shall be
                  determined solely by the express provisions of this Indenture
                  and the Trustee need perform only those duties that are
                  specifically set forth in this Indenture and no others, and no
                  implied covenants or obligations shall be read into this
                  Indenture against the Trustee; and

                           (ii)     in the absence of bad faith on its part, the
                  Trustee may conclusively rely, as to the truth of the
                  statements and the correctness of the opinions expressed
                  therein, upon certificates or opinions furnished to the
                  Trustee and conforming to the requirements of this Indenture.
                  However, the Trustee shall examine the certificates and
                  opinions to determine whether or not they conform on their
                  face to the requirements of this Indenture.

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

                           (i)      this paragraph does not limit the effect of
                  paragraph (b) of this Section;

                           (ii)     the Trustee shall not be liable for any
                  error of judgment made in good faith by a Responsible Officer,
                  unless it is proved that the Trustee was negligent in
                  ascertaining the pertinent facts; and

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

                  (d)      Whether or not therein expressly so provided, every
provision of this Indenture that in any way relates to the Trustee is subject to
paragraphs (a), (b) and (c) of this Section 7.01.

                  (e)      No provision of this Indenture shall require the
Trustee to expend or risk its own funds or incur any liability. The Trustee
shall be under no obligation to exercise any of the rights or powers vested in
it by this Indenture at the request or direction of any of the Holders unless
such Holders shall have offered to the Trustee security or indemnity reasonably
satisfactory to it against the costs, expenses and liabilities that might be
incurred by it in compliance with such request or direction.

                  (f)      Money held in trust by the Trustee need not be
segregated from other funds and need not be held in an interest-bearing account,
in each case except to the extent required by law or by any other provision of
this Indenture.

Section 7.02. Certain Rights of Trustee.

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

                  (b)      Before the Trustee acts or refrains from acting, it
may require an Officers' Certificate or an Opinion of Counsel or both. The
Trustee shall not be liable for any action it takes or omits to take in good
faith in reliance on such Officers' Certificate or Opinion of Counsel. The
Trustee may consult with counsel and the advice of such counsel or any Opinion
of Counsel shall be full and complete authorization and protection from
liability in respect of any action taken, suffered or omitted by it hereunder in
good faith and in reliance thereon.

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

                  (d)      The Trustee shall not be liable for any action it
takes or omits to take in good faith that it reasonably believes to be
authorized or within the rights or powers conferred upon it by this Indenture.

                  (e)      Unless otherwise specifically provided in this
Indenture, any demand, request, direction or notice from the Company shall be
sufficient if signed by an Officer of the Company.

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

                  (g)      The Trustee shall not be deemed to have notice of any
Default or Event of Default unless a Responsible Officer of the Trustee has
actual knowledge thereof or unless

                                     - 76 -
<PAGE>

written notice of such event is sent to the Trustee in accordance with Section
13.02 hereof, and such notice references the Notes.

Section 7.03. Individual Rights of Trustee.

                  The Trustee in its individual or any other capacity may become
the owner or pledgee of Notes and may become a creditor of, or otherwise deal
with, the Company or any of its Affiliates with the same rights it would have if
it were not Trustee. However, in the event that the Trustee acquires any
conflicting interest as described in the Trust Indenture Act, it must eliminate
such conflict within 90 days, apply to the Commission for permission to continue
as trustee or resign. Any Agent may do the same with like rights and duties. The
Trustee is also subject to Sections 7.10 and 7.11 hereof.

Section 7.04. Trustee's Disclaimer.

                  The Trustee shall not be responsible for and makes no
representation as to the validity or adequacy of this Indenture, it shall not be
accountable for the Company's use of the proceeds from the Notes or any money
paid to the Company or upon the Company's direction under any provision of this
Indenture, it shall not be responsible for the use or application of any money
received by any Paying Agent other than the Trustee, and it shall not be
responsible for any statement or recital herein or any statement in the Notes or
any other document in connection with the sale of the Notes or pursuant to this
Indenture other than its certificate of authentication.

Section 7.05. Notice of Defaults.

                  If a Default or Event of Default occurs and is continuing and
if it is known to the Trustee, the Trustee shall mail to Holders of Notes a
notice of the Default or Event of Default within 90 days after it occurs. Except
in the case of a Default or Event of Default in payment of principal of, premium
or interest on any Note, the Trustee may withhold the notice if and so long as a
committee of its Responsible Officers in good faith determines that withholding
the notice is in the interests of the Holders of the Notes.

Section 7.06. Reports by Trustee to Holders of the Notes.

                  (a)      Within 60 days after each May 15 beginning with the
May 15 following the date hereof, and for so long as Notes remain outstanding,
the Trustee shall mail to the Holders of the Notes a brief report dated as of
such reporting date that complies with TIA Section 313(a) (but if no event
described in TIA Section 313(a) has occurred within the twelve months preceding
the reporting date, no report need be transmitted). The Trustee also shall
comply with TIA Section 313(b)(2). The Trustee shall also transmit by mail all
reports as required by TIA Section 313(c).

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

Section 7.07. Compensation and Indemnity.

                  (a)      The Company shall pay to the Trustee (in its capacity
as Trustee, and, to the extent it has been appointed as such, as Paying Agent
and Registrar) from time to time reasonable compensation for its acceptance of
this Indenture and services hereunder in accordance with a written schedule
provided by the Trustee to the Company. The Trustee's compensation shall not be
limited by any law on compensation of a trustee of an express trust. The Company
shall reimburse the Trustee promptly upon request for all reasonable and
customary disbursements, advances and reasonable out-of-pocket expenses incurred
or made by it in addition to the compensation for its services. Such expenses
shall include the reasonable and customary compensation, disbursements and
expenses of the Trustee's agents and counsel.

                  (b)      The Company shall indemnify the Trustee against any
and all losses, liabilities or reasonable out-of-pocket expenses incurred by it
arising out of or in connection with the acceptance or administration of its
duties under this Indenture, including the costs and expenses of enforcing this
Indenture against the Company (including this Section 7.07) and defending itself
against any claim (whether asserted by either of the Company or any Holder or
any other person) or liability in connection with the exercise or performance of
any of its powers or duties hereunder, except to the extent any such loss,
liability or expense may be attributable to its negligence or bad faith. The
Trustee shall notify the Company promptly of any claim for which it may seek
indemnity. Failure by the Trustee to so notify the Company shall not relieve the
Company of its obligations hereunder. The Company shall defend the claim and the
Trustee shall cooperate in the defense. The Trustee may have separate counsel
and the Company shall pay the reasonable and customary fees and expenses of such
counsel. The Company need not pay for any settlement made without its consent,
which consent shall not be unreasonably withheld.

                  (c)      The obligations of the Company under this Section
7.07 shall survive the satisfaction and discharge of this Indenture.

                  (d)      To secure the Company's payment obligations in this
Section, the Trustee shall have a Lien prior to the Notes on all money or
property held or collected by the Trustee, except that held in trust to pay
principal and interest on particular Notes. Such Lien shall survive the
satisfaction and discharge of this Indenture.

                  (e)      When the Trustee incurs expenses or renders services
after an Event of Default specified in Section 6.01(h) or (i) hereof occurs, 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 any Bankruptcy Law.

Section 7.08. Replacement of Trustee.

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

                  (b)      The Trustee may resign in writing at any time and be
discharged from the trust hereby created by so notifying the Company. The
Holders of a majority in principal

                                     - 78 -
<PAGE>

amount of the then outstanding Notes may remove the Trustee by so notifying the
Trustee and the Company in writing. The Company may remove the Trustee if:

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

                           (ii)     the Trustee is adjudged a bankrupt or an
                  insolvent or an order for relief is entered with respect to
                  the Trustee under any Bankruptcy Law;

                           (iii)    a custodian or public officer takes charge
                  of the Trustee or its property; or

                           (iv)     the Trustee becomes incapable of acting.

                  (c)      If the Trustee resigns or is removed or if a vacancy
exists in the office of Trustee for any reason, the Company shall promptly
appoint a successor Trustee. Within one year after the successor Trustee takes
office, the Holders of a majority in principal amount of the then outstanding
Notes may appoint a successor Trustee to replace the successor Trustee appointed
by the Company.

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

                  (e)      If the Trustee, after written request by any Holder
who has been a Holder for at least six months, fails to comply with Section
7.10, such Holder may petition any court of competent jurisdiction for the
removal of the Trustee and the appointment of a successor Trustee.

                  (f)      A successor Trustee shall deliver a written
acceptance of its appointment to the retiring Trustee and to the Company.
Thereupon, the resignation or removal of the retiring Trustee shall become
effective, and the successor Trustee shall have all the rights, powers and
duties of the Trustee under this Indenture. The successor Trustee shall mail a
notice of its succession to Holders. The retiring Trustee shall promptly
transfer all property held by it as Trustee to the successor Trustee, provided
all sums owing to the Trustee hereunder have been paid and subject to the Lien
provided for in Section 7.07 hereof. Notwithstanding replacement of the Trustee
pursuant to this Section 7.08, the Company's obligations under Section 7.07
hereof shall continue for the benefit of the retiring Trustee.

Section 7.09. Successor Trustee by Merger, Etc.

                  If the Trustee consolidates, merges or converts into, or
transfers all or substantially all of its corporate trust business to, another
Person, the successor Person without any further act shall be the successor
Trustee.

Section 7.10.     Eligibility; Disqualification.

                  There shall at all times be a Trustee hereunder that is a
corporation organized and doing business under the laws of the United States of
America or of any state thereof that is

TIA Section 310(b).

Section 7.11. Preferential Collection of Claims Against Company.

                  The Trustee is subject to TIA Section 311(a), excluding any
creditor relationship listed in TIA Section 311(b). A Trustee who has resigned
or been removed shall be subject to TIA Section 311(a) to the extent indicated
therein. The Trustee hereby waives any right to set-off any claim that it may
have against the Company in any capacity (other than as Trustee and Paying
Agent) against any of the assets of the Company held by the Trustee; provided,
however, that if the Trustee is or becomes a lender of any other Indebtedness
permitted hereunder to be pari passu with the Notes, then such waiver shall not
apply to the extent of such Indebtedness.

                       DEFEASANCE AND COVENANT DEFEASANCE

Section 8.01.     Option to Effect Legal Defeasance or Covenant Defeasance.

                  The Company may, at the option of the Board evidenced by a
resolution set forth in an Officers' Certificate, at any time, elect to have
either Section 8.02 or 8.03 hereof be applied to all outstanding Notes upon
compliance with the conditions set forth below in this Article Eight.

Section 8.02. Legal Defeasance and Discharge.

                  Upon the Company's exercise under Section 8.01 hereof of the
option applicable to this Section 8.02, the Company shall, subject to the
satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to
have been discharged from its obligations with respect to all outstanding Notes
and all obligations of the Guarantors shall be deemed to have been discharged
with respect to their obligations under the Guarantees on the date the
conditions set forth below are satisfied (hereinafter, "legal defeasance"). For
this purpose, Legal Defeasance means that the Company and the Guarantors shall
be deemed to have paid and discharged the entire Indebtedness represented by the
outstanding Notes and Guarantees, respectively, which shall thereafter be deemed
to be "outstanding" only for the purposes of Section 8.05 hereof and the other
Sections of this Indenture referred to in (a) and (b) below, and to have
satisfied all its other obligations under such Notes and this Indenture (and the
Trustee, on demand of and at the expense of the Company, shall execute proper
instruments acknowledging the same), except for the following provisions which
shall survive until otherwise terminated or discharged hereunder: (a) the rights
of Holders of outstanding Notes to receive solely from the trust fund described
in Section 8.04 hereof, and as more fully set forth in such Section, payments in
respect of the principal of, premium, if any, and interest on such Notes when
such payments are due, (b) the Company's obligations with respect to such Notes

                                     - 80 -
<PAGE>

(c) the rights, powers, trusts, duties and immunities of the Trustee hereunder
and the Company's obligations in connection therewith and (d) this Article 8.
Subject to compliance with this Article 8, the Company may exercise its option
under this Section 8.02 notwithstanding the prior exercise of its option under
Section 8.03 hereof.

Section 8.03. Covenant Defeasance.

                  Upon the Company's exercise under Section 8.01 hereof of the
option applicable to this Section 8.03, the Company shall, subject to the
satisfaction of the conditions set forth in Section 8.04 hereof, be released
from its obligations under the covenants contained in Sections 4.03, 4.07, 4.08,
4.09, 4.10, 4.11, 4.12, 4.13, 4.14, 4.15, 4.16, 4.17, 4.19, 4.20 and 5.01 hereof
with respect to the outstanding Notes on and after the date the conditions set
forth in Section 8.04 are satisfied (hereinafter, "Covenant Defeasance"), and
the Notes shall thereafter be deemed 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 (it being
understood that such Notes shall not be deemed outstanding for accounting
purposes). For this purpose, Covenant Defeasance means that, with respect to the
outstanding Notes, the Company may omit to comply with and shall have no
liability in respect of any term, condition or limitation set forth in any such
covenant, whether directly or indirectly, by reason of any reference elsewhere
herein to any such covenant or by reason of any reference in any such covenant
to any other provision herein or in any other document and such omission to
comply shall not constitute a Default or an Event of Default under Section 6.01
hereof, but, except as specified above, the remainder of this Indenture and such
Notes shall be unaffected thereby. In addition, upon the Company's exercise
under Section 8.01 hereof of the option applicable to this Section 8.03, subject
to the satisfaction of the conditions set forth in Section 8.04 hereof, Sections
6.01(c) through (g) shall not constitute Events of Default.

Section 8.04. Conditions to Legal or Covenant Defeasance.

                  (a)      The following shall be the conditions to the
application of either Section 8.02 or 8.03 hereof to the outstanding Notes:

                  cause to be deposited with the Trustee, as trust funds in
                  trust, specifically pledged as security for, and dedicated
                  solely to, the benefit of the Holders, money in an amount, or

                  amount, or a combination thereof, sufficient, in the opinion
                  of a nationally recognized firm of independent public
                  accountants, investment bank or appraisal firm, to pay and

                  interest;

                           (ii)     no Default or Event of Default has occurred
                  and is continuing on the date of such deposit or, insofar as
                  an event of bankruptcy under Section 6.01(h) is concerned, at
                  any time during the period ending on the 91st day after the
                  date of such deposit;

                           (iii)    such Legal Defeasance or Covenant Defeasance
                  may not result in a breach or violation of, or constitute a
                  default under, this Indenture, the Credit Agreement or any
                  material agreement or instrument to which the Company or any
                  Guarantor is a party or by which it is bound;

                           (iv)     in the case of Legal Defeasance, the Company
                  must deliver to the Trustee an Opinion of Counsel stating that
                  the Company has received from, or there has been published by,
                  the Internal Revenue Service a ruling, or, since the Closing
                  Date, there has been a change in applicable federal income tax
                  law, to the effect, and based thereon such opinion must
                  confirm, that the Holders of the outstanding Notes will not
                  recognize income, gain or loss for federal income tax purposes
                  as a result of such Legal Defeasance and will be subject to
                  federal income tax on the same amounts, in the same manner and
                  at the same times as would have been the case if such Legal
                  Defeasance had not occurred;

                           (v)      in the case of Covenant Defeasance, the
                  Company must have delivered to the Trustee an Opinion of
                  Counsel to the effect that the Holders of the outstanding
                  Notes 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; and

                           (vi)     the Company must have delivered to the
                  Trustee an Officers' Certificate and an Opinion of Counsel,
                  each stating that all conditions precedent provided for
                  relating to either the Legal Defeasance or the Covenant
                  Defeasance, as the case may be, have been complied with.

Section 8.05. Deposited Money and U.S. Government Obligations to Be Held in
              Trust; Other Miscellaneous Provisions.

                  (a)      Subject to Section 8.06 hereof, all money and
non-callable U.S. Government Obligations (including the proceeds thereof)
deposited with the Trustee (or other qualifying trustee, collectively for
purposes of this Section 8.05, the "Trustee") pursuant to Section 8.04 hereof in
respect of the outstanding Notes shall be held in trust and applied by the
Trustee, in accordance with the provisions of such Notes and this Indenture, to
the payment, either directly or through any Paying Agent (including the Company
acting as Paying Agent) as the Trustee may determine, to the Holders of such
Notes of all sums due and to become due thereon in respect of principal, premium
and interest, but such money need not be segregated from other funds except to
the extent required by law.

                  (b)      The Company shall pay and indemnify the Trustee
against any tax, fee or other charge imposed on or assessed against the cash or
non-callable U.S. Government Obligations deposited pursuant to Section 8.04
hereof or the principal and interest received in respect thereof other than any
such tax, fee or other charge which by law is for the account of the Holders of
the outstanding Notes.

                                     - 82 -
<PAGE>

                  (c)      Anything in this Article Eight to the contrary
notwithstanding, the Trustee shall deliver or pay to the Company from time to
time upon the request of the Company any money or non-callable U.S. Government
Obligations held by it as provided in Section 8.04 hereof which, in the opinion
of a nationally recognized firm of independent public accountants, investment
bank, or appraisal firm expressed in a written certification thereof delivered
to the Trustee (which may be the opinion delivered under Section 8.04(a)
hereof), are in excess of the amount thereof that would then be required to be
deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

Section 8.06.     Repayment to the Company.

                  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 Note and remaining unclaimed for two years after such
principal, and premium, if any, or interest has become due and payable shall be
paid to the Company on its request or (if then held by the Company) shall be
discharged from such trust; and the Holder of such Note shall thereafter 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; provided, however, that the
Trustee or such Paying Agent, before being required to make any such repayment,
may at the expense of the Company cause to be published once, in the New York
Times and The Wall Street Journal (national edition), notice that such money
remains unclaimed and that, after a date specified therein, which shall not be
less than 30 days from the date of such notification or publication, any
unclaimed balance of such money then remaining shall be repaid to the Company.

Section 8.07. Reinstatement.

                  If the Trustee or Paying Agent is unable to apply any United
States dollars or non-callable U.S. Government Obligations in accordance with
Section 8.02 or 8.03 hereof, 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 Notes shall be revived and reinstated as though no
deposit had occurred pursuant to Section 8.02 or 8.03 hereof until such time as
the Trustee or Paying Agent is permitted to apply all such money in accordance
with Section 8.02 or 8.03 hereof, as the case may be; provided, however, that,
if the Company makes any payment of principal of, premium, if any, or interest
on any Note following the reinstatement of its obligations, the Company shall be
subrogated to the rights of the Holders of such Notes to receive such payment
from the money held by the Trustee or Paying Agent.

or the Notes without the consent of any Holder of a Note:

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

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

                           (iii)    to add additional Events of Defaults; or

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

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

                           (vi)     to secure the Notes; or

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

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

                           (ix)     to provide for the issuance of Additional
                  Notes in accordance with the limitations set forth in this
                  Indenture as of its date; or

                           (x)      to allow any Guarantor to execute a
                  supplemental Indenture and a Guarantee with respect to the
                  Notes; or (xi) to provide for the issuance of the Exchange
                  Notes pursuant to the terms of this Indenture.

                  Notwithstanding the foregoing, and so long as the Credit
Agreement is outstanding, neither the Company nor the Trustee may amend any
provisions of this Indenture or the Notes concerning the subordination of the
Notes and the Guarantees without the prior written consent of the Agent Bank,
acting on behalf of the Banks under the Credit Agreement.

                  (b)      Upon the request of the Company accompanied by a
resolution of its Board authorizing the execution of any such amended or
supplemental Indenture, and upon receipt by the Trustee of the documents
described in Section 7.02 hereof, the Trustee shall join with the Company in the
execution of any amended or supplemental Indenture authorized or permitted by
the terms of this Indenture and to make any further appropriate agreements and
stipulations that may be therein contained, but the Trustee shall not be
obligated to enter into

                                     - 84 -
<PAGE>

such amended or supplemental Indenture that affects its own rights, duties or
immunities under this Indenture or otherwise.

Section 9.02. With Consent of Holders of Notes.

                  (a)      Except as provided below in this Section 9.02, the
Company the Guarantors and the Trustee may amend or supplement this Indenture or
the Notes with the consent of the Holders of at least a majority in principal
amount of the Notes (including Additional Notes, if any) then outstanding
(including, without limitation, consents obtained in connection with a purchase
of, or tender offer or exchange offer for, Notes), and, subject to Sections 6.04
and 6.07 hereof, any existing Default or Event of Default or compliance with any
provision of this Indenture or the Notes may be waived with the consent of the
Holders of a majority in principal amount of the then outstanding Notes
(including Additional Notes, if any) (including, without limitation, consents
obtained in connection with a purchase of, or tender offer or exchange offer
for, Notes).

                  (b)      The Company may, but shall not be obligated to, fix a
record date for the purpose of determining the Persons entitled to consent to
any indenture supplemental hereto. If a record date is fixed, the Holders on
such record date, or its duly designated proxies, and only such Persons, shall
be entitled to consent to such supplemental indenture, whether or not such
Holders remain Holders after such record date; provided that unless such consent
shall have become effective by virtue of the requisite percentage having been
obtained prior to the date which is 90 days after such record date, any such
consent previously given shall automatically and without further action by any
Holder be cancelled and of no further effect.

                  (c)      Upon the request of the Company accompanied by a
resolution of its Board authorizing the execution of any such amended or
supplemental Indenture, and upon the filing with the Trustee of evidence
reasonably satisfactory to the Trustee of the consent of the Holders of Notes as
aforesaid, and upon receipt by the Trustee of the documents described in Section
7.02 hereof, the Trustee shall join with the Company in the execution of such
amended or supplemental Indenture unless such amended or supplemental Indenture
directly affects the Trustee's own rights, duties or immunities under this
Indenture or otherwise, in which case the Trustee may in its discretion, but
shall not be obligated to, enter into such amended or supplemental Indenture.

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

                  (e)      After an amendment, supplement or waiver under this
Section becomes effective, the Company shall mail to the Holders of Notes
affected thereby a notice briefly describing the amendment, supplement or
waiver. Any failure of the Company to mail such notice, or any defect therein,
shall not, however, in any way impair or affect the validity of any such amended
or supplemental Indenture or waiver. Subject to Sections 6.04 and 6.07 hereof,
the Holders of a majority in aggregate principal amount of the then outstanding
Notes (including Additional Notes, if any) may waive compliance in a particular
instance by the Company with any provision of this Indenture, or the Notes.
However, without the consent of each Holder

                                     - 85 -
<PAGE>

affected, an amendment or waiver under this Section 9.02 may not (with respect
to any Notes held by a non-consenting Holder):

                           (i)      change the Stated Maturity of the principal
                  of, or any installment of interest on, any Note, or reduce the
                  principal amount thereof or the rate of interest thereon or
                  any premium payable upon the redemption thereof, or change the
                  coin or currency in which any Note or any premium or the
                  interest thereon are payable, or impair the right to institute
                  suit for the enforcement of any such payment after the Stated
                  Maturity thereof (or, in the case of redemption, on or after
                  the redemption date);

                           (ii)     amend, change or modify (A) Section 4.18
                  hereof or (B) the obligation of the Company to make and
                  consummate a Change of Control Offer in the event of a Change
                  of Control in accordance with Section 4.15 hereof, including,
                  amending, changing or modifying any definition relating
                  thereto;

                           (iii)    reduce the percentage in principal amount of
                  outstanding Notes, the consent of whose Holders is required
                  for any waiver of compliance with certain provisions of, or
                  certain defaults and their consequences provided for under,
                  this Indenture;

                           (iv)     waive a Default or Event of Default in the
                  payment of principal of, or premium, if any, or interest on
                  the Notes;

                           (v)      modify the subordination provisions of the
                  Notes or the Guarantee of any Guarantor;

                           (vi)     release any Guarantor from any of its
                  obligations under its Guarantee or this Indenture other than
                  in accordance with the terms of this Indenture; or

                           (vii)    make any change in the preceding amendment
                  and waiver provisions.

Section 9.03. Compliance with Trust Indenture Act.

                  Every amendment or supplement to this Indenture or the Notes
shall be set forth in an amended or supplemental Indenture that complies with
the TIA as then in effect.

Section 9.04.     Revocation and Effect of Consents.

                  Until an amendment, supplement or waiver becomes effective, a
consent to it by a Holder of a Note is a continuing consent by the Holder of a
Note and every subsequent Holder of a Note or portion of a Note that evidences
the same debt as the consenting Holder's Note, even if notation of the consent
is not made on any Note. However, any such Holder of a Note or subsequent Holder
of a Note may revoke the consent as to its Note if the Trustee receives written
notice of revocation before the date the waiver, supplement or amendment becomes
effective.

                                     - 86 -
<PAGE>

An amendment, supplement or waiver becomes effective in accordance with its
terms and thereafter binds every Holder.

Section 9.05. Notation on or Exchange of Notes.

                  (a)      The Trustee may place an appropriate notation about
an amendment, supplement or waiver on any Note thereafter authenticated. The
Company in exchange for all Notes may issue and the Trustee shall, upon receipt
of an Authentication Order, authenticate new Notes that reflect the amendment,
supplement or waiver.

                  (b)      Failure to make the appropriate notation or issue a
new Note shall not affect the validity and effect of such amendment, supplement
or waiver.

Section 9.06. Trustee to Sign Amendments, Etc.

                  The Trustee shall sign any amended or supplemental indenture
or Note authorized pursuant to this Article Nine if the amendment or supplement
does not adversely affect the rights, duties, liabilities or immunities of the
Trustee. The Company may not sign an amendment or supplemental Indenture or Note
until its Board approves it. In executing any amended or supplemental indenture
or Note, the Trustee shall be entitled to receive and (subject to Section 7.01
hereof) shall be fully protected in relying upon an Officers' Certificate and an
Opinion of Counsel stating that the execution of such amended or supplemental
indenture is authorized or permitted by this Indenture.

                                  SUBORDINATION

Section 10.01. Agreement to Subordinate.

                  The Company agrees, and each Holder by accepting a Note
agrees, that the Indebtedness evidenced by the Notes and any other payment
obligations on or with respect to the Notes (including any obligation to
repurchase the Notes) is subordinated in right of payment, to the extent and in
the manner provided in this Article Ten, to the prior payment in full of all
Senior Indebtedness (whether outstanding on the date hereof or hereafter
created, incurred, assumed or guaranteed), and that the subordination is for the
benefit of the holders of Senior Indebtedness.

Section 10.02. Liquidation; Dissolution; Bankruptcy.

                  The holders of Senior Indebtedness of the Company will be
entitled to receive payment in full of all Obligations due in respect of Senior
Indebtedness of the Company (including interest after the commencement of any
bankruptcy proceeding at the rate specified in the applicable Senior
Indebtedness of the Company) before the Holders will be entitled to receive any
payment with respect to the Notes (except that Holders may receive and retain
equity securities of the Company or debt securities of the Company or a
Guarantor that are subordinated at least to the same extent as the Notes and
Guarantees are subordinated to Senior Indebtedness and any debt securities
issued in exchange for Senior Indebtedness ("Permitted Junior Securities") and
payments made from the trust pursuant to Article Eight hereunder), in the event

                                     - 87 -
<PAGE>

of any distribution to creditors of the Company: (i) in a liquidation or
dissolution of the Company; (ii) in a bankruptcy, reorganization, insolvency,
receivership or similar proceeding relating to the Company or its property;
(iii) in an assignment for the benefit of creditors; or (iv) in any marshaling
of the Company's assets and liabilities.

Section 10.03. Default on Designated Senior Indebtedness.

                  (a)      The Company may not make any payment in respect of
the Notes (except in Permitted Junior Securities or from the trust pursuant to
Article Eight hereof):

                           (i)      in the event any default in the payment of
                  principal of, interest or premium, if any, on Designated
                  Senior Indebtedness occurs (a "Payment Event of Default"); or

                           (ii)     any Non-Payment Event of Default occurs and
                  is continuing with respect to Designated Senior Indebtedness
                  which permits holders of the Designated Senior Indebtedness as
                  to which such default relates to accelerate its maturity and
                  the Trustee receives a notice of such default (a "Payment
                  Blockage Notice") from (A) with respect to the Designated
                  Senior Indebtedness arising under the Credit Agreement, the
                  Agent Bank, or (B) with respect to any other Designated Senior
                  Indebtedness, the holders or the representative of the holders
                  of any such Designated Senior Indebtedness.

                           (iii)    Payments on the Notes may and shall be
                  resumed (x) in the case of a Payment Event of Default, upon
                  the date on which such default is cured or waived and (y) in
                  case of a Non-Payment Event of Default, upon the earlier of
                  the date on which such Non-Payment Event of Default is cured
                  or waived or 179 days after the date on which the applicable
                  Payment Blockage Notice is received unless the maturity of any
                  Designated Senior Indebtedness has been accelerated. No new
                  period of payment blockage may be commenced by a Payment
                  Blockage Notice unless and until (i) 360 days have elapsed
                  since the first day of the effectiveness of the immediately
                  prior Payment Blockage Notice and (ii) all scheduled payments
                  of principal, premium, if any, and interest on the Notes that
                  have come due have been paid in full in cash. No Non-Payment
                  Event of Default that existed or was continuing on the date of
                  delivery of any Payment Blockage Notice to the Trustee shall
                  be, or be made, the basis for a subsequent Payment Blockage
                  Notice, unless such default has been cured or waived for a
                  period of not less than 90 days.

Section 10.04. Acceleration of Notes.

                  If payment of the Notes is accelerated because of an Event of
Default, the Company shall promptly notify holders of Senior Indebtedness of the
acceleration.

Section 10.05. When Distribution Must Be Paid Over.

                  (a)      In the event that the Trustee or any Holder receives
any payment of any Obligations with respect to the Notes (except in Permitted
Junior Securities or from the trust

                                     - 88 -
<PAGE>

pursuant to Article Eight hereof) at a time when such payment is prohibited by
Article Ten hereof and the Trustee or such Holder, as applicable, has actual
knowledge that such payment is prohibited by Article Ten hereof, such payment
shall be held by the Trustee or such Holder, as applicable, in trust for the
benefit of the holders of Senior Indebtedness of the Company. Upon proper
written request of the holders of Senior Indebtedness of the Company, the
Trustee or such Holder, as the case may be, shall deliver the amounts in trust
to the holders of Senior Indebtedness or their proper Representative under the
indenture or other agreement (if any) pursuant to which Senior Indebtedness may
have been issued, as their respective interests may appear, for application to
the payment of all Obligations with respect to Senior Indebtedness remaining
unpaid to the extent necessary to pay such Obligations in full in accordance
with their terms, after giving effect to any concurrent payment or distribution
to or for the holders of Senior Indebtedness.

                  (b)      With respect to the holders of Senior Indebtedness,
the Trustee undertakes to perform only such obligations on the part of the
Trustee as are specifically set forth in this Article Ten, and no implied
covenants or obligations with respect to the holders of Senior Indebtedness
shall be read into this Indenture against the Trustee. The Trustee shall not be
deemed to owe any fiduciary duty to the holders of Senior Indebtedness, and
shall not be liable to any such holders if the Trustee shall pay over or
distribute to or on behalf of Holders or the Company or any other Person money
or assets to which any holders of Senior Indebtedness shall be entitled by
virtue of this Article Ten, except if such payment is made as a result of the
willful misconduct or gross negligence of the Trustee.

Section 10.06. Notice by the Company.

                  The Company shall promptly notify the Trustee and the Paying
Agent in writing of any facts known to the Company that would cause a payment of
any Obligations with respect to the Notes to violate this Article Ten, but
failure to give such notice shall not affect the subordination of the Notes to
the Senior Indebtedness as provided in this Article Ten.

Section 10.07. Subrogation.

                  After all Senior Indebtedness is paid in full and until the
Notes are paid in full, Holders shall be subrogated (equally and ratably with
the holders of all Indebtedness of the Company which by its express terms is
subordinated to Senior Indebtedness of the Company to the same extent as the
Notes are subordinated and which is entitled to like rights of subrogation) to
the rights of holders of Senior Indebtedness to receive distributions applicable
to Senior Indebtedness to the extent that distributions otherwise payable to the
Holders have been applied to the payment of Senior Indebtedness. A distribution
made under this Article Ten to holders of Senior Indebtedness that otherwise
would have been made to Holders is not, as between the Company and Holders, a
payment by the Company on the Notes.

Section 10.08. Relative Rights.

                  (a)      This Article Ten defines the relative rights of
Holders and holders of Senior Indebtedness. Nothing in this Indenture shall:

                                     - 89 -
<PAGE>

                           (i)      impair, as between the Company and Holders,
                  the obligation of the Company, which is absolute and
                  unconditional, to pay principal of and interest on the Notes
                  in accordance with their terms;

                           (ii)     affect the relative rights of Holders of
                  Notes and creditors of the Company other than their rights in
                  relation to holders of Senior Indebtedness; or

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

                  (b)      If the Company fails because of this Article Ten to
pay principal of or interest on a Note on the due date, the failure is still a
Default or Event of Default.

Section 10.09. Subordination May Not Be Impaired by the Company.

                  No right of any holder of Senior Indebtedness to enforce the
subordination of the Indebtedness evidenced by the Notes shall be impaired by
any act or failure to act by the Company or any Holder or by the failure of the
Company or any Holder to comply with this Indenture.

Section 10.10. Distribution or Notice to Representative.

                  (a)      Whenever a distribution is to be made or a notice
given to holders of Senior Indebtedness, the distribution may be made and the
notice given to their Representative.

                  (b)      Upon any payment or distribution of assets of the
Company referred to in this Article Ten, the Trustee and the Holders of Notes
shall be entitled to rely upon any order or decree made by any court of
competent jurisdiction or upon any certificate of such Representative or of the
liquidating trustee or agent or other Person making any distribution to the
Trustee or to the Holders of Notes for the purpose of ascertaining the Persons
entitled to participate in such distribution, the holders of the 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 Ten.

Section 10.11. Rights of Trustee and Paying Agent.

                  (a)      Notwithstanding the provisions of this Article Ten or
any other provision of this Indenture, the Trustee shall not be charged with
knowledge of the existence of any facts that would prohibit the making of any
payment or distribution by the Trustee, and the Trustee and the Paying Agent may
continue to make payments on the Notes, unless the Trustee shall have received
at its Corporate Trust Office at least five Business Days prior to the date of
such payment written notice of facts that would cause the payment of any
Obligations with respect to the Notes to violate this Article Ten. Only the
Company or a Representative may give the notice. Nothing in this Article Ten
shall impair the claims of, or payments to, the Trustee under or pursuant to
Section 7.07 hereof.

                                     - 90 -
<PAGE>

                  (b)      The Trustee in its individual or any other capacity
may hold Senior Indebtedness with the same rights it would have if it were not
Trustee. Any Agent may do the same with like rights.

Section 10.12. Authorization to Effect Subordination.

                  Each Holder, by the Holder's acceptance thereof, agrees and
directs the Trustee on such Holder's behalf to take such action as may be
necessary or appropriate to effectuate the subordination as provided in this
Article Ten, and appoints the Trustee to act as such Holder's attorney-in-fact
for any and all such purposes. If the Trustee does not file a proper proof of
claim or proof of debt in the form required in any proceeding referred to in
Section 6.09 hereof at least 30 days before the expiration of the time to file
such claim, the lenders under the Credit Agreement are hereby authorized to file
an appropriate claim for and on behalf of the Holders of the Notes.

                                 ARTICLE ELEVEN
                                   GUARANTEES

Section 11.01. Guarantee.

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

                  (b)      The Guarantors hereby agree that their obligations
hereunder shall be unconditional, irrespective of the validity, regularity or
enforceability of the Notes or this Indenture, the absence of any action to
enforce the same, any waiver or consent by any Holder of the Notes with respect
to any provisions hereof or thereof, the recovery of any judgment against the
Company, any action to enforce the same or any other circumstance which might
otherwise constitute a legal or equitable discharge or defense of a Guarantor.
Subject to Section 6.06 hereof, each Guarantor hereby waives diligence,
presentment, demand of payment, filing of claims with a court in the event of
insolvency or bankruptcy of the Company, any right to require a proceeding first
against the Company, protest, notice and all demands whatsoever and covenant

                                     - 91 -
<PAGE>

that this Guarantee shall not be discharged except by complete performance of
the obligations contained in the Notes and this Indenture.

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

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

Section 11.02. Subordination of Guarantee.

                  The Obligations of each Guarantor under its Guarantee pursuant
to this Article Eleven shall be junior and subordinated to the prior payment in
full of all Senior Indebtedness of such Guarantor (including Senior Indebtedness
of the Guarantor incurred after the date hereof) on the same basis as the Notes
are junior and subordinated to the prior payment in full all Senior Indebtedness
of the Company, as described in Article Ten hereof. For the purposes of the
foregoing sentence, the Trustee and the Holders shall have the right to receive
and/or retain payments by any of the Guarantors only at such times as they may
receive and/or retain payments in respect of the Notes pursuant to this
Indenture, including Article Ten hereof.

Section 11.03. Limitation on Guarantor Liability.

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

                                     - 92 -
<PAGE>

obligations of such Guarantor under its Guarantee not constituting a fraudulent
transfer or conveyance.

                  Until such time as the Notes 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 Eleven.

Section 11.04. Execution and Delivery of Guarantee.

                  (a)      To evidence its Guarantee set forth in Section 11.01,
each Guarantor hereby agrees that a notation of such Guarantee substantially in
the form included in Exhibit E shall be endorsed by an Officer of such Guarantor
by manual or facsimile signature on each Note authenticated and delivered by the
Trustee and that this Indenture shall be executed on behalf of such Guarantor by
any of its executive officers by manual or facsimile signature.

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

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

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

                  (e)      In the event that the Company creates or acquires any
new Wholly Owned Restricted Subsidiaries subsequent to the date of this
Indenture, if required by Section 4.20 hereof, the Company shall cause such
Subsidiaries to execute supplemental indentures to this Indenture and Guarantees
in accordance with Section 4.20 hereof and this Article Eleven, to the extent
applicable.

Section 11.05. Releases of Guarantors.

                  (a)      A Guarantor will be deemed automatically and
unconditionally released and discharged from all of its obligations under its
Guarantee without any further action on the part of the Trustee or any Holder of
the Notes in accordance with Section 4.19(b) hereof; provided that any such
termination shall occur only if the Trustee is furnished with written notice of
such release together with an Officers' Certificate from such Guarantor to the
effect that all of the conditions to release in Section 4.19(b) have been
satisfied.

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

                           SATISFACTION AND DISCHARGE

Section 12.01. Satisfaction and Discharge.

                  (a)      This Indenture shall be discharged and shall cease to
be of further effect as to all Notes issued thereunder, when:

                           (i)      either:

                                    (A)      all Notes that have been
                           authenticated (except lost, stolen or destroyed Notes
                           that have been replaced or paid and Notes for whose
                           payment money has theretofore been deposited in trust
                           and thereafter repaid to the Company) have been
                           delivered to the Trustee for cancellation; or

                                    (B)      all Notes that have not been
                           delivered to the Trustee for cancellation have become
                           due and payable by reason of the making of a notice
                           of redemption or otherwise or will become due and
                           payable within one year and the Company or any
                           Guarantor has irrevocably deposited or caused to be
                           deposited with the Trustee as trust funds in trust
                           solely for the benefit of the Holders, cash in U.S.
                           dollars, non-callable U.S. Government Obligations, or
                           a combination thereof, in such amounts as will be
                           sufficient without consideration of any reinvestment
                           of interest, to pay and discharge the entire
                           indebtedness on the Notes not delivered to the
                           Trustee for cancellation for principal, premium and
                           accrued interest to the date of maturity or
                           redemption;

                           (ii)     no Default or Event of Default shall have
                  occurred and be continuing on the date of such deposit or
                  shall occur as a result of such deposit and such deposit will
                  not result in a breach or violation of, or constitute a
                  default under, any other instrument to which the Company or
                  any Guarantor is a party or by which the Company or any
                  Guarantor is bound;

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

                           (iv)     the Company has delivered irrevocable
                  instructions to the Trustee hereunder to apply the deposited
                  money toward the payment of the Notes at maturity or the
                  redemption date, as the case may be.

                  (b)      In addition, the Company must deliver an Officers'
Certificate and an Opinion of Counsel (which opinion may be subject to customary
assumptions and exclusions) to the Trustee stating that all conditions precedent
to satisfaction and discharge have been satisfied.

                  (c)      Notwithstanding the above, the Trustee shall pay to
the Company from time to time upon its request any cash or U.S. Government
Obligations held by it as provided in this section which, in the opinion of a
nationally recognized firm of independent public

                                     - 94 -

accountants expressed in a written certification delivered to the Trustee, are
in excess of the amount thereof that would then be required to be deposited to
effect a satisfaction and discharge under this Article Twelve.

Section 12.02. Deposited Money and U.S. Government Obligations to be held in
               Trust; Other Miscellaneous Provisions.

                  Subject to Section 12.03 hereof, all money and non-callable
U.S. Government Obligations (including the proceeds thereof) deposited with the
Trustee (or other qualifying trustee, collectively for purposes of this Section
12.02, the "trustee") pursuant to Section 12.01 hereof in respect of the
outstanding Notes shall be held in trust and applied by the Trustee, in
accordance with the provisions of such Notes and this Indenture, to the payment,
either directly or through any Paying Agent (including the Company acting as
Paying Agent) as the Trustee may determine, to the Holders of such Notes of all
sums due and to become due thereon in respect of principal, premium and
interest, but such money need not be segregated from other funds except to the
extent required by law.

Section 12.03. Repayment to the Company.

                  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
or interest on any Note and remaining unclaimed for two years after such
principal, and premium, if any, or interest has become due and payable shall be
paid to the Company on its request or (if then held by the Company) shall be
discharged from such trust; and the Holder of such Note shall thereafter 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; provided, however, that the
Trustee or such Paying Agent, before being required to make any such repayment,
may at the expense of the Company cause to be published once, in the New York
Times or The Wall Street Journal (national edition), notice that such money
remains unclaimed and that, after a date specified therein, which shall not be
less than 30 days from the date of such notification or publication, any
unclaimed balance of such money then remaining shall be repaid to the Company.

non-exclusive) of such courts in any such suit, action or proceeding. Service of
any process, summons, notice or document by mail to such party's address set

Section 13.10. No Adverse Interpretation of Other Agreements.

                  This Indenture may not be used to interpret any other
indenture, loan or debt agreement of the Company or any of its Subsidiaries or
of any other Person. Any such indenture, loan or debt agreement may not be used
to interpret this Indenture.

Section 13.11. Successors.

                  All agreements of the Company in this Indenture and the Notes
shall bind its successors. All agreements of the Trustee in this Indenture shall
bind its successors. All agreements of each Guarantor in this Indenture shall
bind its successors, except as otherwise provided in Section 5.01.

Section 13.12. Severability.

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

Section 13.13. Counterpart Originals.

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

Section 13.14. 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 the Holders may be embodied in and evidenced by one or more
instruments of substantially similar tenor signed by such Holders in person or
by agents duly appointed in writing, and may be given or obtained in connection
with a purchase of, or tender offer or exchange offer for, outstanding Notes;
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 13.14.

                  (b)      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 such witness,
notary or officer the execution thereof. Where such execution is by a signer
acting in a capacity other than his individual capacity, such certificate or
affidavit shall also constitute sufficient proof of 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.

                  (c)      Notwithstanding anything to the contrary contained in
this Section 13.14, the principal amount and serial numbers of Notes held by any
Holder, and the date of holding the same, shall be proved by the register of the
Notes maintained by the Registrar as provided in Section 2.04 hereof.

                  (d)      If the Company shall solicit from the Holders of the
Notes any request, demand, authorization, direction, notice, consent, waiver or
other Act, the Company may, at its option, by or pursuant to a resolution of its
Board, fix in advance a record date for the determination of 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
TIA Section 316(c), such record date shall be the record date specified in or
pursuant to such resolution, which shall be a date not earlier than the date 30
days prior to the first solicitation of Holders generally in connection
therewith or the date of the most recent list of Holders forwarded to the
Trustee prior to such solicitation pursuant to Section 2.06 hereof and not later
than the date such 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 the purposes of determining whether Holders of the requisite
proportion of the then outstanding Notes have authorized or agreed or consented
to such request, demand, authorization, direction, notice, consent, waiver or
other Act, and for that purpose the then outstanding Notes shall be computed as
of such record date; provided that no such authorization, agreement or consent
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
eleven months after the record date.

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

                  (f)      Without limiting the foregoing, a Holder entitled
hereunder to take any action hereunder with regard to any particular Note may do
so itself with regard to all or any part of the principal amount of such Note or
by one or more duly appointed agents each of which may do so pursuant to such
appointment with regard to all or any part of such principal amount.

                  (g)      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 13.15. Benefit of Indenture.

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

the Articles and Sections of this Indenture have been inserted for convenience
of reference only, are not to be considered a part of this Indenture and shall

Section 13.17. Trustee Not Fiduciary for Holders of Senior Indebtedness.

                  The Trustee shall not be deemed to owe any fiduciary duty to
the holders of Senior Indebtedness and shall not be liable to any such holders
if it shall in good faith mistakenly pay over or distribute to Holders or the
Company or to any other Person cash, property or securities to which any holders
of Senior Indebtedness shall be entitled by virtue of this Agreement or
otherwise.

                  4. Indenture. The Company issued the Notes under an Indenture
dated as of October 22, 2003 (the "Indenture") among the Company, the Guarantors
and the Trustee. The terms of the Notes include those stated in the Indenture
and those made part of the Indenture by reference to the Trust Indenture Act of
1939, as amended. The Notes are subject to all such terms, and Holders are
referred to the Indenture and such Act for a statement of such terms. To the
extent any provision of this Note conflicts with the express provisions of the
Indenture, the provisions of the Indenture shall govern and be controlling. The
Indenture pursuant to which this Note is issued provides that an unlimited
amount of Additional Notes may be issued thereunder, subject to compliance with
the covenants therein.

                  5. Optional Redemption. (a) At any time on or prior to
November 1, 2007, the Company may, on any one or more occasions, redeem all or a

                  principal of the Notes being redeemed plus scheduled payments
                  of interest (not including any portion of such payments of
                  interest accrued as of the date of redemption) from the date
                  of redemption to November 1, 2007 discounted for each such
                  amount to the redemption date on a semiannual basis (assuming
                  a 360-day year consisting of twelve 30-day months) at the
                  Adjusted Treasury Rate plus 50 basis points, together with
                  accrued and unpaid interest, if any, to the date of
                  redemption.

                  (b)      After November 1, 2007, the Notes will be redeemable,

                  (c)      Notwithstanding the foregoing, at any time or from
time to time prior to November 1, 2006, the Company may redeem on one or more
occasions, up to 35% of the aggregate principal amount of the Notes issued
hereunder with the net proceeds of one or more Public Equity Offerings at a
redemption price equal to 109% of the principal amount thereof, plus accrued
interest, if any, to the redemption date (subject to the right of Holders of
record on the relevant record date to receive interest due on an interest
payment date); provided that, immediately after giving effect to such
redemption, at least 65% of the aggregate principal amount of the Notes issued
under this Indenture remains outstanding; provided further that such redemptions
shall occur within 90 days of the date of the closing of each such Public Equity
Offering.

                  6. Mandatory Redemption. Except as set forth in paragraph 7
below, the Company shall not be required to make mandatory redemption or sinking
fund payments with respect to the Notes.

                  7. Repurchase at Option of Holders. (a) Upon the occurrence of
a Change of Control, each Holder of Notes will have the right to require the
Company to repurchase all or any part (equal to $1,000 or an integral multiple
thereof) of such Holder's Notes pursuant to the procedures set forth in the
Indenture at an offer price in cash equal to 101% of the aggregate principal
amount thereof plus accrued and unpaid interest [and Liquidated Damages]**
thereon, if any, to the date of purchase.

                  (b) Upon Asset Sales, the Company may be obligated to make
offers, in accordance with the procedures set forth in the Indenture, to
purchase Notes with a portion of the Net Cash Proceeds of such Asset Sales at a
redemption price of 100% of the principal amount thereof plus accrued and unpaid
interest [and Liquidated Damages],** if any, to the date of purchase.

                  8. Selection and Notice of Redemption. If less than all of the
Notes are to be redeemed or purchased in an offer to purchase at any time, the
Trustee shall select the Notes to be redeemed or purchased among the Holders of
the Notes not more than 90 days prior to the redemption date, or otherwise in
compliance with the requirements of the principal national securities exchange,
if any, on which the Notes are listed or, if the Notes are not so listed, on a
pro rata basis, by lot or in accordance with any other method the Trustee
considers fair and appropriate. In the event of partial redemption by lot, the
particular Notes to be redeemed shall be selected, unless otherwise provided
herein, not less than 30 nor more than 60 days prior to the redemption date by
the Trustee from the outstanding Notes not previously called for redemption.

Notices of redemption may not be conditional. If any Note is to be redeemed in
part only, the notice of redemption that relates to that Note will state the
portion of the principal amount thereof to be redeemed. A new Note in principal
amount equal to the unredeemed portion of the original Note will be issued in
the name of the Holder thereof upon cancellation of the original Note. Notes
called for redemption become due on the date fixed for redemption. On and after
the redemption date, interest [and Liquidated Damages],** if any, cease to
accrue on Notes or portions of them called for redemption.

                  9. Denominations, Transfer, Exchange. The Notes are in
registered form without coupons in denominations of $1,000 and integral
multiples of $1,000. The transfer of Notes may be registered and Notes may be
exchanged as provided in the Indenture. The Registrar and the Trustee may
require a Holder, among other things, to furnish appropriate endorsements and
transfer documents and the Company may require a Holder to pay any taxes and
fees required by law or permitted by the Indenture. The Company is not required
to transfer or exchange any Note selected for redemption. Also, the Company is
not required to transfer or exchange any Note for a period of 15 days before a
selection of Notes to be redeemed.

                  10. Persons Deemed Owners. The registered Holder of a Note
will be treated as its owner for all purposes.

                  11. Amendment, Supplement and Waiver. The Indenture or the
Notes may be amended or supplemented only as provided in the Indenture.

                  12. Defaults and Remedies. In the case of an Event of Default
arising from certain events of bankruptcy or insolvency, with respect to the
Company or any Restricted Subsidiary that is a Significant Subsidiary, all
outstanding Notes will become due and payable immediately without further action
or notice. If any other Event of Default occurs and is continuing, the Trustee
or the Holders of at least 25% in principal amount of the then outstanding Notes
may declare all the Notes to be due and payable immediately by notice in writing
to the Company specifying the respective Event of Default. The Trustee may
withhold from Holders of the Notes notice of any continuing Default or Event of
Default (except a Default or Event of Default relating to the payment of
principal or interest [or Liquidated Damages],** if any) if it determines that
withholding notice is in their interest. The Holders of a majority in aggregate
principal amount of the Notes then outstanding by notice to the Trustee may on
behalf of the Holders of all of the Notes waive any existing Default or Event of
Default and its consequences under the Indenture except a continuing Default or
Event of Default in the payment of interest [or Liquidated Damages],** if any,
on, or the principal of, the Notes.

                  13. Trustee Dealings with Company. The Trustee, in its
individual or any other capacity, may make loans to, accept deposits from, and
perform services for the Company or its Affiliates, and may otherwise deal with
the Company or its Affiliates, as if it were not the Trustee.

                  14. No Recourse Against Others. No past, present or future
director, officer, employee, incorporator or stockholder of the Company or any
Guarantor, as such, shall have any

liability for any obligations of the Company or the Guarantors under the Notes,
the Indenture, the Guarantees or the Registration Rights Agreement, as
applicable, or any claim based on, in respect of, or by reason of, such
obligations or their creation. Each Holder by accepting a Note waives and
releases all such liability. The waiver and release are part of the
consideration for issuance of the Notes. Such waiver may not be effective to
waive liabilities under the federal securities laws.

                  15. Authentication. This Note shall not be valid until
authenticated by the manual signature of the Trustee or an authenticating agent.

                  16. Additional Rights of Holders of Restricted Global Notes
and Restricted Definitive Notes. [In addition to the rights provided to Holders
under the Indenture, Holders of Restricted Global Notes and Restricted
Definitive Notes shall have all the rights set forth in the Registration Rights
Agreement dated as of October 22, 2003,* between the Company, the Guarantors and
the parties named on the signature pages thereof.]**

                  17. CUSIP Numbers. Pursuant to a recommendation promulgated by
the Committee on Uniform Security Identification Procedures, the Company has
caused CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP
numbers in notices of redemption as a convenience to Holders. No representation
is made as to the accuracy of such numbers either as printed on the Notes or as
contained in any notice of redemption and reliance may be placed only on the
other identification numbers placed thereon.

                  18. Governing Law. This Note shall be governed by and
construed in accordance with the laws of the State of New York.

                  The Company shall furnish to any Holder upon written request
and without charge a copy of the Indenture and/or the Registration Rights
Agreement. Requests may be made to:

                      9% Senior Subordinated Notes due 2011

                  Capitalized terms used herein shall have the meanings assigned
to them in the Indenture referred to below unless otherwise indicated.

Date"). Interest on the Notes shall accrue from the most recent date to which
interest has been paid or, if no interest has been paid, from the date of

Bankruptcy Law) on overdue installments of interest [and Liquidated Damages]**
(without regard to any applicable grace periods) from time to time on demand at
the same rate to the extent lawful. Interest shall be computed on the basis of a
360-day year of twelve 30-day months. If a payment date is not a Business Day,

interest shall accrue on such payment for the intervening period.

                  2. Method of Payment. The Company shall pay interest on the
Notes (except defaulted interest [and Liquidated Damages],** if any), to the
Persons who are registered Holders of Notes at the close of business on the 15th
day of the month next preceding the Interest Payment Date, even if such Notes
are canceled after such record date and on or before such Interest Payment Date,
except as provided in Section 2.13 of the Indenture with respect to defaulted
interest. The Company shall pay all Liquidated Damages, if any, on the date of
its choosing and in the amounts set forth in the Registration Rights Agreement.

if any, and interest at the office or agency of the Company maintained for such
purpose in The City of New York, or, at the option of the Company, payment of

Notes and all other Notes the Holders of which shall have
provided wire transfer instructions to the Company or the Paying Agent. Such

Minnesota, N.A., the Trustee under the Indenture, shall act as Paying Agent and
Registrar. The Company may change any Paying Agent or Registrar without notice
to any Holder. The Company or any of its Subsidiaries may act in any such
capacity.

                  4. Indenture. The Company issued the Notes under an Indenture
dated as of October 22, 2003 (the "Indenture") among the Company, the Guarantors
and the Trustee. The terms of the Notes include those stated in the Indenture
and those made part of the Indenture by reference to the Trust Indenture Act of
1939, as amended. The Notes are subject to all such terms, and Holders are
referred to the Indenture and such Act for a statement of such terms. To the
extent any provision of this Note conflicts with the express provisions of the
Indenture, the provisions of the Indenture shall govern and be controlling. The
Indenture pursuant to which this Note is issued provides that an unlimited
amount of Additional Notes may be issued thereunder, subject to compliance with
the covenants therein.

                  5. Optional Redemption. (a) At any time on or prior to
November 1, 2007, the Company may, on any one or more occasions, redeem all or a
portion of the Notes, on not less than 30 nor more than 60 days' prior notice,
in amounts of $1,000 or an integral multiple thereof, at a price equal to the

                  principal of the Notes being redeemed plus scheduled payments
                  of interest (not including any portion of such payments of
                  interest accrued as of the date of redemption) from the date
                  of redemption to November 1, 2007 discounted for each such
                  amount to the redemption date on a semiannual basis (assuming
                  a 360-day year consisting of twelve 30-day months) at the
                  Adjusted Treasury Rate plus 50 basis points, together with
                  accrued and unpaid interest, if any, to the date of
                  redemption.

                  (d)      After November 1, 2007, the Notes will be redeemable,

less than 30 nor more than 60 days' prior notice to the Holders at the following
redemption prices (expressed as percentages of principal amount), together with
accrued interest, if any, to the redemption date (subject to the right of
Holders of record on the relevant record date to receive interest due on an
interest payment date), if redeemed during the 12-month period beginning on
November 1 of the years indicated below.

                  (e)      Notwithstanding the foregoing, at any time or from
time to time prior to November 1, 2006, the Company may redeem on one or more
occasions, up to 35% of the aggregate principal amount of the Notes issued
hereunder with the net proceeds of one or more Public Equity Offerings at a
redemption price equal to 109% of the principal amount thereof, plus accrued
interest, if any, to the redemption date (subject to the right of Holders of
record on the relevant record date to receive interest due on an interest
payment date); provided that, immediately after giving effect to such
redemption, at least 65% of the aggregate principal amount of the Notes issued
under this Indenture remains outstanding; provided further that such redemptions
shall occur within 90 days of the date of the closing of each such Public Equity
Offering.

                  6. Mandatory Redemption. Except as set forth in paragraph 7
below, the Company shall not be required to make mandatory redemption or sinking
fund payments with respect to the Notes.

                  7. Repurchase at Option of Holders. (a) Upon the occurrence of
a Change of Control, each Holder of Notes will have the right to require the
Company to repurchase all or any part (equal to $1,000 or an integral multiple
thereof) of such Holder's Notes pursuant to the procedures set forth in the
Indenture at an offer price in cash equal to 101% of the aggregate principal
amount thereof plus accrued and unpaid interest [and Liquidated Damages]**
thereon, if any, to the date of purchase.

                  (b)      Upon Asset Sales, the Company may be obligated to
make offers, in accordance with the procedures set forth in the Indenture, to
purchase Notes with a portion of the Net Cash Proceeds of such Asset Sales at a
redemption price of 100% of the principal amount thereof plus accrued and unpaid
interest [and Liquidated Damages],** if any, to the date of purchase.

                  8. Selection and Notice of Redemption. If less than all of the
Notes are to be redeemed or purchased in an offer to purchase at any time, the
Trustee shall select the Notes to be redeemed or purchased among the Holders of
the Notes not more than 90 days prior to the redemption date, or otherwise in
compliance with the requirements of the principal national securities exchange,
if any, on which the Notes are listed or, if the Notes are not so listed, on a
pro rata basis, by lot or in accordance with any other method the Trustee
considers fair and appropriate. In the event of partial redemption by lot, the
particular Notes to be redeemed shall be selected, unless otherwise provided
herein, not less than 30 nor more than 60 days prior to the redemption date by
the Trustee from the outstanding Notes not previously called for redemption.

                                      A2-8
<PAGE>

Notices of redemption may not be conditional. If any Note is to be redeemed in
part only, the notice of redemption that relates to that Note will state the
portion of the principal amount thereof to be redeemed. A new Note in principal
amount equal to the unredeemed portion of the original Note will be issued in
the name of the Holder thereof upon cancellation of the original Note. Notes
called for redemption become due on the date fixed for redemption. On and after
the redemption date, interest [and Liquidated Damages],** if any, cease to
accrue on Notes or portions of them called for redemption.

                  9. Denominations, Transfer, Exchange. The Notes are in
registered form without coupons in denominations of $1,000 and integral
multiples of $1,000. The transfer of Notes may be registered and Notes may be
exchanged as provided in the Indenture. The Registrar and the Trustee may
require a Holder, among other things, to furnish appropriate endorsements and
transfer documents and the Company may require a Holder to pay any taxes and
fees required by law or permitted by the Indenture. The Company is not required
to transfer or exchange any Note selected for redemption. Also, the Company is
not required to transfer or exchange any Note for a period of 15 days before a
selection of Notes to be redeemed.

                  10. Persons Deemed Owners. The registered Holder of a Note
will be treated as its owner for all purposes.

                  11. Amendment, Supplement and Waiver. The Indenture or the
Notes may be amended or supplemented only as provided in the Indenture.

                  12. Defaults and Remedies. In the case of an Event of Default
arising from certain events of bankruptcy or insolvency, with respect to the
Company or any Restricted Subsidiary that is a Significant Subsidiary, all
outstanding Notes will become due and payable immediately without further action
or notice. If any other Event of Default occurs and is continuing, the Trustee
or the Holders of at least 25% in principal amount of the then outstanding Notes
may declare all the Notes to be due and payable immediately by notice in writing
to the Company specifying the respective Event of Default. The Trustee may
withhold from Holders of the Notes notice of any continuing Default or Event of
Default (except a Default or Event of Default relating to the payment of
principal or interest [or Liquidated Damages],** if any) if it determines that
withholding notice is in their interest. The Holders of a majority in aggregate
principal amount of the Notes then outstanding by notice to the Trustee may on
behalf of the Holders of all of the Notes waive any existing Default or Event of
Default and its consequences under the Indenture except a continuing Default or
Event of Default in the payment of interest [or Liquidated Damages],** if any,
on, or the principal of, the Notes.

                  13. Trustee Dealings with Company. The Trustee, in its
individual or any other capacity, may make loans to, accept deposits from, and
perform services for the Company or its Affiliates, and may otherwise deal with
the Company or its Affiliates, as if it were not the Trustee.

                  14. No Recourse Against Others. No past, present or future
director, officer, employee, incorporator or stockholder of the Company or any
Guarantor, as such, shall have any

                                      A2-9

liability for any obligations of the Company or the Guarantors under the Notes,
the Indenture, the Guarantees or the Registration Rights Agreement, as
applicable, or any claim based on, in respect of, or by reason of, such
obligations or their creation. Each Holder by accepting a Note waives and
releases all such liability. The waiver and release are part of the
consideration for issuance of the Notes. Such waiver may not be effective to
waive liabilities under the federal securities laws.

                  15. Authentication. This Note shall not be valid until
authenticated by the manual signature of the Trustee or an authenticating agent.

                  16. Additional Rights of Holders of Restricted Global Notes
and Restricted Definitive Notes. [In addition to the rights provided to Holders
under the Indenture, Holders of Restricted Global Notes and Restricted
Definitive Notes shall have all the rights set forth in the Registration Rights
Agreement dated as of October 22, 2003,* between the Company, the Guarantors and
the parties named on the signature pages thereof.]**

                  17. CUSIP Numbers. Pursuant to a recommendation promulgated by
the Committee on Uniform Security Identification Procedures, the Company has
caused CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP
numbers in notices of redemption as a convenience to Holders. No representation
is made as to the accuracy of such numbers either as printed on the Notes or as
contained in any notice of redemption and reliance may be placed only on the
other identification numbers placed thereon.

                  18. Governing Law. This Note shall be governed by and
construed in accordance with the laws of the State of New York.

                  The Company shall furnish to any Holder upon written request
and without charge a copy of the Indenture and/or the Registration Rights
Agreement. Requests may be made to:

Indenture and any applicable blue sky securities laws of any state of the United

providing for the issuance of 9% Senior Subordinated Notes due 2011 (the
"Notes");

                  WHEREAS, the Indenture provides that under certain
circumstances the Guaranteeing Subsidiary shall execute and deliver to the
Trustee a supplemental indenture pursuant to which the Guaranteeing Subsidiary
shall unconditionally guarantee all of the Company's obligations under the Notes

severally Guarantee to each Holder of a Note authenticated and delivered by the
Trustee and to the Trustee and its successors and assigns, irrespective of the
validity and enforceability of the Indenture, the Notes or the obligations of
the Company hereunder or thereunder, that:

                           (i)      the principal of and interest on the Notes
                  will be promptly paid in full when due, whether at maturity,
                  by acceleration, redemption or otherwise, and interest on the
                  overdue principal of and interest on the Notes, if any, if

                  thereunder will be promptly paid in full or performed, all in
                  accordance with the terms hereof and thereof; and

                           (ii)     in case of any extension of time of payment
                  or renewal of any Notes or any of such other obligations, the

                  shall be jointly and severally obligated to pay the same
                  immediately.

                  (v)      The obligations hereunder shall be unconditional,
         irrespective of the validity, regularity or enforceability of the Notes
         or the Indenture, the absence of any action to enforce the same, any
         waiver or consent by any Holder of the Notes with respect to any
         provisions hereof or thereof, the recovery of any judgment against the
         Company, any action to enforce the same or any other circumstance that
         might otherwise constitute a legal or equitable discharge or defense of
         a guarantor.

                  (w)      The following are hereby waived: diligence,
         presentment, demand of payment, filing of claims with a court in the
         event of insolvency or bankruptcy of the Company, any right to require
         a proceeding first against the Company, protest, notice and all demands
         whatsoever.

                  (x)      This Guarantee shall not be discharged except by
         complete performance of the obligations contained in the Notes and the
         Indenture.

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

                  (z)      The Guaranteeing Subsidiary shall not be entitled to
         any right of subrogation in relation to the Holders in respect of any
         obligations guaranteed hereby until payment in full of all obligations
         guaranteed hereby.

                  (aa)     As between the Guarantors, on the one hand, and the
         Holders and the Trustee, on the other hand, (x) the maturity of the
         obligations guaranteed hereby may be accelerated as provided in Article
         Six of the Indenture for the purposes of this Guarantee,
         notwithstanding any stay, injunction or other prohibition preventing
         such acceleration in respect of the obligations guaranteed hereby, and
         (y) in the event of any declaration of acceleration of such obligations
         as provided in Article Six of the Indenture, such obligations (whether
         or not due and payable) shall forthwith become due and payable by the
         Guarantors for the purpose of this Guarantee.

                  (bb)     Pursuant to Section 10.02 of the Indenture, after
giving effect to any maximum amount and any other contingent and fixed
liabilities that are relevant under any applicable Bankruptcy or fraudulent
conveyance laws, and after giving effect to any collections

                                      F-2
<PAGE>

from, rights to receive contribution from or payments made by or on behalf of
any other Guarantor in respect of the obligations of such other Guarantor under
Article Ten of the Indenture shall result in the obligations of such Guarantor
under its Guarantee not constituting a fraudulent transfer or conveyance.

                  3. Subordination. The Obligations of the Guaranteeing
Subsidiary under its Guarantee pursuant to this Supplemental Indenture shall be
junior and subordinated to the Senior Indebtedness of the Guaranteeing
Subsidiary on the same basis as the Notes are junior and subordinated to the
Senior Indebtedness of the Company. For the purposes of the foregoing sentence,
the Trustee and the Holders shall have the right to receive and/or retain
payments by the Guaranteeing Subsidiary only at such time as they may receive
and/or retain payments in respect of the Notes pursuant to the Indenture,
including Article Ten thereof.

                  4. Execution and Delivery. Each Guaranteeing Subsidiary agrees
that the Guarantees shall remain in full force and effect notwithstanding any
failure to endorse on each Note a notation of such Guarantee.

                  5. Guaranteeing Subsidiary May Consolidate, Etc., on Certain
Terms.

                  Except as otherwise provided in Section 11.05 of the
Indenture, a Guarantor may not consolidate with or merge with or into any other
Person or convey, sell, assign, transfer, lease or otherwise dispose of its
properties and assets substantially as an entirety to any other Person (other
than the Company or another Guarantor) unless:

                  (cc)     subject to the provisions of the following paragraph,
the Person formed by or surviving such consolidation or merger (if other than
such Guarantor) or to which such properties and assets are transferred assumes
all of the obligations of such Guarantor under this Indenture and its Guarantee,
pursuant to a supplemental indenture in form and substance satisfactory to the
Trustee;

                  (dd)     immediately after giving effect to such transaction,
no Default or Event of Default has occurred and is continuing; and

                  (ee)     the Guarantor delivers, or causes to be delivered, to
the Trustee, in form and substance reasonably satisfactory to the Trustee, an
Officers' Certificate and an Opinion of Counsel, each stating that such
transaction complies with the requirements of this Indenture.

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

                  In case of any such consolidation, merger, sale or conveyance
and upon the assumption by the successor Person, by supplemental indenture,
executed and delivered to the Trustee and reasonably satisfactory in form to the
Trustee, of the Guarantee endorsed upon the Notes and the due and punctual
performance of all of the covenants and conditions of the Indenture to be
performed by a Guarantor, such successor Person shall succeed to and be

                                      F-3
<PAGE>

substituted for a Guarantor with the same effect as if it had been named herein
as a Guarantor. Such successor Person thereupon may cause to be signed any or
all of the Guarantees to be endorsed upon all of the Notes issuable hereunder
which theretofore shall not have been signed by the Company and delivered to the
Trustee. All the Guarantees so issued shall in all respects have the same legal
rank and benefit under the Indenture as the Guarantees theretofore and
thereafter issued in accordance with the terms of the Indenture as though all of
such Guarantees had been issued at the date of the execution hereof.

                  6.       Releases.

                  (a)      A Guarantor will be deemed automatically and
unconditionally released and discharged from all of its obligations under its
Guarantee without any further action on the part of the Trustee or any Holder of
the Notes upon a sale or other disposition to a Person not an Affiliate of the
Company of all of the Capital Stock of, or all or substantially all of the
assets of, such Guarantor, by way of merger, consolidation or otherwise, which
transaction is carried out in accordance with Section 4.10 hereof; provided that
any such termination shall occur (x) only to the extent that all obligations of
such Guarantor under all of its guarantees of, and under all of its pledges of
assets or other security interests which secure any Indebtedness of the Company
shall also terminate upon such sale, disposition or release and (y) only if the
Trustee is furnished with written notice of such release together with an
Officers' Certificate from such Guarantor to the effect that all of the
conditions to release in this Section 6 have been satisfied.

                  (b)      Any Guarantor not released from its obligations under
its Guarantee shall remain liable for the full amount of principal of and
interest on the Notes and for the other obligations of any Guarantor under the
Indenture as provided in Article Eleven of the Indenture.

                  7. No Recourse Against Others. No director, officer, employee,
incorporator or stockholder of the Company or any Guarantor, as such, shall have
any liability for any obligations of the Company or the Guarantors under the
Notes, 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 Notes by
accepting a Note waives and releases all such liability. The waiver and release
are part of the consideration for issuance of the Notes. The waiver may not be
effective to waive liabilities under the federal securities laws.

                  8. NEW YORK LAW TO GOVERN. THE INTERNAL LAW OF THE STATE OF
NEW YORK SHALL GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL INDENTURE BUT
WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT
THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED
THEREBY.
