            "CONSOLIDATED COVERAGE RATIO" means as of any date of determination,
with respect to any Person, the ratio of (x) the aggregate amount of
Consolidated EBITDA of such Person for the period of the most recent four
consecutive fiscal quarters ending prior to the date of such determination for
which financial statements are in existence to (y) Consolidated Interest Expense
for such four fiscal quarters, PROVIDED, HOWEVER, that:

            (1)      if the Company or any Restricted Subsidiary:

                     (a)    has Incurred any Indebtedness since the beginning of
                            such period that remains outstanding on such date of
                            determination or if the transaction giving rise to
                            the need to calculate the Consolidated Coverage
                            Ratio is an Incurrence of Indebtedness, Consolidated
                            EBITDA and Consolidated Interest Expense for such
                            period will be calculated after giving effect on a
                            pro forma basis to such Indebtedness as if such
                            Indebtedness had been Incurred on the first day of
                            such period (except that in making such computation,
                            the amount of Indebtedness under any revolving
                            credit facility outstanding on the date of such
                            calculation will be deemed to be (i) the average
                            daily balance of such Indebtedness during such four
                            fiscal quarters or such shorter period for which
                            such facility was outstanding or (ii) if such
                            facility was created after the end of such four
                            fiscal quarters, the average daily balance of such
                            Indebtedness during the period from the date of
                            creation of such facility to the date of such
                            calculation) and the discharge of any other
                            Indebtedness repaid, repurchased, defeased or
                            otherwise discharged with the proceeds of such new
                            Indebtedness as if such discharge had occurred on
                            the first day of such period; or

                     (b)    has repaid, repurchased, defeased or otherwise
                            discharged any Indebtedness since the beginning of
                            the period that is no longer outstanding on such
                            date of determination or if the transaction giving
                            rise to the need to calculate the Consolidated
                            Coverage Ratio involves a discharge of Indebtedness
                            (in each case other than Indebtedness Incurred under
                            any revolving credit facility unless such
                            Indebtedness has been permanently repaid and the
                            related commitment terminated), Consolidated EBITDA
                            and Consolidated Interest Expense for such period
                            will be calculated after giving effect on a pro
                            forma basis to such discharge of such Indebtedness,
                            including with the proceeds of such new
                            Indebtedness, as if such discharge had occurred on
                            the first day of such period;

            (2)      if since the beginning of such period the Company or any
                     Restricted Subsidiary will have disposed of any company,
                     division, diagnostic imaging center, operating unit,
                     segment, business, group of related assets or line of
                     business or if the transaction giving rise to the need to
                     calculate the Consolidated Coverage Ratio is such an Asset
                     Disposition:

                     (a)    the Consolidated EBITDA for such period will be
                            reduced by an amount equal to the Consolidated
                            EBITDA (if positive) directly attributable to the
                            assets which are the subject of such Asset
                            Disposition for such period or increased by an
                            amount equal to the Consolidated EBITDA (if
                            negative) directly attributable thereto for such
                            period; and

                     (b)    Consolidated Interest Expense for such period will
                            be reduced by an amount equal to the Consolidated
                            Interest Expense directly attributable to any
                            Indebtedness of the Company or any Restricted
                            Subsidiary repaid, repurchased, defeased or
                            otherwise discharged with respect to the Company and
                            its continuing Restricted Subsidiaries in connection
                            with such Asset Disposition for such period (or, if
                            the Capital Stock of any Restricted Subsidiary is
                            sold, the Consolidated Interest Expense for such
                            period directly attributable to the Indebtedness of
                            such Restricted Subsidiary to the extent the Company
                            and its continuing Restricted Subsidiaries are no
                            longer liable for such Indebtedness after such
                            sale);

            (3)      if since the beginning of such period the Company or any
                     Restricted Subsidiary (by merger or otherwise) will have
                     made an Investment in any Restricted Subsidiary (or any
                     Person which becomes a Restricted Subsidiary or is merged
                     with or into the Company) or an acquisition of assets,
                     including any acquisition of assets occurring in connection
                     with a transaction causing a calculation to be made
                     hereunder, which constitutes all or substantially all of
                     any company, division, diagnostic imaging center, operating
                     unit, segment, business, group of related assets or line of
                     business, Consolidated EBITDA and Consolidated Interest
                     Expense for such period will be calculated after giving pro
                     forma effect thereto (including the Incurrence of any
                     Indebtedness) as if such Investment or acquisition occurred
                     on the first day of such period; and

            (4)      if since the beginning of such period any Person (that
                     subsequently became a Restricted Subsidiary or was merged
                     with or into the Company or any Restricted Subsidiary since
                     the beginning of such period) will have Incurred any
                     Indebtedness or discharged any Indebtedness, made any Asset
                     Disposition or any Investment or acquisition of assets that
                     would have required an adjustment pursuant to clause (2) or
                     (3) above if made by the Company or a Restricted Subsidiary
                     during such period, Consolidated EBITDA and Consolidated
                     Interest Expense for such period will be calculated after
                     giving pro forma effect thereto as if such Incurrence,
                     discharge, Asset Disposition or Investment or acquisition
                     of assets occurred on the first day of such period.

            For purposes of this definition, whenever pro forma effect is to be
given to any calculation under this definition, the pro forma calculations will
be determined in good faith by a responsible financial or accounting officer of
the Company. Any such pro forma calculations

<Page>

                                                                               9

may include operating expense reductions for such period resulting from the
acquisition which is being given pro forma effect that (a) would be permitted
pursuant to Article 11 of Regulation S-X under the Securities Act or (b) have
been realized or for which the steps necessary for realization have been taken
or are reasonably expected to be taken within six months following any such
acquisition, including, but not limited to, the execution or termination of any
contracts, the termination of any personnel or the closing (or approval by the
Board of Directors of any closing) of any diagnostic imaging center or facility,
as applicable, PROVIDED that such adjustments are set forth in an Officers'
Certificate signed by the Company's Chief Financial Officer and another Officer
which states (i) the amount of such adjustment or adjustments, (ii) that such
adjustment or adjustments are based on the reasonable good faith beliefs of the
Officers executing such Officers' Certificate at the time of such execution and
(iii) that any related Incurrence of Indebtedness is permitted pursuant to this
Indenture. In addition, to the extent not covered by the foregoing, if the
Transactions have occurred in the four quarter period used to determine the
Consolidated Coverage Ratio, then the Consolidated Coverage Ratio shall be
determined giving pro forma effect on the basis given in the Offering Memorandum
to the Transactions, with all calculations relating thereto to be made at the
date of determination by the Company's Chief Financial Officer, and set forth in
an Officers' Certificate signed by the Chief Financial Officer and another
Officer of the Company and meeting the requirements for the Officers'
Certificate described in the preceding sentence. If any Indebtedness bears a
floating rate of interest and is being given pro forma effect, the interest
expense on such Indebtedness 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 Interest Rate Agreement applicable to such Indebtedness if such
Interest Rate Agreement has a remaining term in excess of 12 months). If any
Indebtedness that is being given pro forma effect bears an interest rate at the
option of the Company, the interest rate shall be calculated by applying such
optional rate chosen by the Company.

            "CONSOLIDATED EBITDA" for any period means, without duplication, the
Consolidated Net Income for such period, plus the following to the extent
deducted in calculating such Consolidated Net Income:

            (3)      consolidated depreciation expense;

            (6)      other non-cash charges reducing Consolidated Net Income
                     (excluding any such non-cash charge to the extent it
                     represents an accrual of or reserve for cash charges in any
                     future period or amortization of a prepaid cash expense
                     that was paid in a prior period not included in the
                     calculation);

Income to compute Consolidated EBITDA of such Person only to the extent (and in
the same proportion) that the net income (loss) of such Restricted Subsidiary
was included in calculating the Consolidated Net Income of such Person and, to
the extent the amounts set forth in clauses (2) through (6) are in excess of
those necessary to offset a net loss of such Restricted Subsidiary or if such
Restricted Subsidiary has net income for such period included in Consolidated
Net Income, only if a corresponding amount would be permitted at the date of
determination to be dividended to the Company by such Restricted Subsidiary
without prior approval (that has not been obtained), pursuant to the terms of
its charter and all agreements, instruments, judgments, decrees, orders,
statutes, rules and governmental regulations applicable to that Restricted
Subsidiary or its stockholders.

            "CONSOLIDATED INCOME TAXES" means, with respect to any Person for
any period, taxes imposed upon such Person or other payments required to be made
by such Person by any governmental authority which taxes or other payments are
calculated by reference to the income or profits of such Person or such Person
and its Restricted Subsidiaries (to the extent such income or profits were

whether such taxes or payments are required to be remitted to any governmental
authority.

                     pursuant to GAAP, such amortization of bond premium has
                     otherwise reduced Consolidated Interest Expense);

                     amortization of fees), PROVIDED, HOWEVER, that if Hedging
                     Obligations result in net benefits rather than costs, such
                     benefits shall be credited to reduce Consolidated Interest
                     Expense unless, pursuant to GAAP, such net benefits are
                     otherwise reflected in Consolidated Net Income;

            (7)      the consolidated interest expense of such Person and its
                     Restricted Subsidiaries that was capitalized during such

            (9)      the cash contributions to any employee stock ownership plan
                     or similar trust to the extent such contributions are used
                     by such plan or trust to pay interest or fees to any Person
                     (other than the Company) in connection with Indebtedness
                     Incurred by such plan or trust; PROVIDED, HOWEVER, that
                     there will be excluded therefrom any such interest expense
                     of any Unrestricted Subsidiary to the extent the related
                     Indebtedness is not Guaranteed or paid by the Company or

                            Partner and (ii) the amount of such obligations to
                            the extent that there is recourse, by contract or
                            operation of law, to the property or assets of such

            The Initial Securities, the Additional Securities and the Exchange

                                                                              40

            Initial Securities and Additional Restricted Securities offered and
sold to QIBs in the United States of America in reliance on Rule 144A (the "RULE
144A NOTES") shall be issued in the form of a permanent global Security, without
interest coupons, substantially in the form of EXHIBIT A, which is hereby
incorporated by reference and made a part of this Indenture, including
appropriate legends as set forth in SECTION 2.1(d) (the "RULE 144A GLOBAL
NOTE"), deposited with the Trustee, as custodian for DTC, duly executed by the
Company and authenticated by the Trustee as hereinafter provided. The Rule 144A
Global Note may be represented by more than one certificate, if so required by
DTC's rules regarding the maximum principal amount to be represented by a single
certificate. The aggregate principal amount of the Rule 144A Global Note may
from time to time be increased or decreased by adjustments made on the records
of the Trustee, as custodian for DTC or its nominee, as hereinafter provided.

            Initial Securities and Additional Securities offered and sold
outside the United States of America (the "REGULATION S NOTES") in reliance on
Regulation S shall initially be issued in the form of a temporary global
Security (the "TEMPORARY REGULATION S GLOBAL NOTE"), without interest coupons.
Beneficial interest in the Temporary Regulation S Global Note will be exchanged
for beneficial interests in a corresponding permanent global Security, without
interest coupons, substantially in the form of EXHIBIT A including appropriate
legends as set forth in SECTION 2.1(d) (the "PERMANENT REGULATION S GLOBAL NOTE"
and, together with the Temporary Regulation S Global Note, each a "REGULATION S
GLOBAL NOTE") within a reasonable period after the expiration of the Restricted
Period (as defined below) upon delivery of the certification contemplated by
SECTION 2.7. Each Regulation S Global Note will be deposited upon issuance with,
or on behalf of, the Trustee as custodian for DTC in the manner described in
this ARTICLE II for credit to the respective accounts of the purchasers (or to
such other accounts as they may direct) at Euroclear Bank S.A./N.V.
("EUROCLEAR") or Clearstream Banking, societe anonyme ("CLEARSTREAM"). Prior to
the 40th day after the later of the commencement of the offering of the Initial
Securities and the Issue Date (such period through and including such 40th day,
the "RESTRICTED PERIOD"), interests in the Temporary Regulation S Global Note
may only be held through Euroclear or Clearstream (as indirect participants in
DTC) unless exchanged for interests in a Global Security in accordance with the
transfer and certification requirements described herein.

            Investors may hold their interests in the Regulation S Global Note
directly through Euroclear or Clearstream, if they are participants in such
systems, or indirectly through organizations which are participants in such
systems. After the expiration of the Restricted Period (but not earlier),
investors may also hold such interests through organizations other than
Euroclear or Clearstream that are participants in DTC's system. Euroclear and
Clearstream will hold such interests in the applicable Regulation S Global Note
on behalf of their participants through customers' securities accounts in their
respective names on the books of their respective depositaries. Such
depositaries, in turn, will hold such interests in the applicable Regulation S
Global Note in customers' securities accounts in the depositaries' names on the
books of DTC.

            The Regulation S Global Note may be represented by more than one
certificate, if so required by DTC's rules regarding the maximum principal
amount to be represented by a single certificate. The aggregate principal amount
of the Regulation S Global Note may from time to time be increased or decreased
by adjustments made on the records of the Trustee, as custodian for DTC or its
nominee, as hereinafter provided.

            Initial Securities and Additional Securities resold to IAIs (the
"INSTITUTIONAL ACCREDITED INVESTOR NOTES") in the United States of America shall
be issued in the form of a permanent global Security, without interest coupons,
substantially in the form of EXHIBIT A including appropriate legends as set
forth in SECTION 2.1(d) (the "INSTITUTIONAL ACCREDITED INVESTOR GLOBAL NOTE")
deposited with the Trustee, as custodian for DTC, duly executed by the Company
and authenticated by the Trustee as hereinafter provided. The Institutional
Accredited Investor Global Note may be represented by more than one certificate,
if so required by DTC's rules regarding the maximum principal amount to be
represented by a single certificate. The aggregate principal amount of the
Institutional Accredited Investor Global Note may from time to time be increased
or decreased by adjustments made on the records of the Trustee, as custodian for
DTC or its nominee, as hereinafter provided.

            Exchange Securities exchanged for interests in the Rule 144A Notes,
the Regulation S Notes and the Institutional Accredited Investor Notes will be
issued in the form of a permanent global Security, without interest coupons,
substantially in the form of EXHIBIT B, which is hereby incorporated by
reference and made a part of this Indenture, deposited with the Trustee as
hereinafter provided, including the appropriate legend set forth in SECTION
2.1(d) (the "EXCHANGE GLOBAL NOTE"). The Exchange Global Note may be represented
by more than one certificate, if so required by DTC's rules regarding the
maximum principal amount to be represented by a single certificate.

            The Rule 144A Global Note, the Regulation S Global Note, the
Institutional Accredited Investor Global Note and the Exchange Global Note are
sometimes collectively herein referred to as the "GLOBAL SECURITIES."

            The principal of (and premium, if any) and interest on the
Securities shall be payable at the office or agency of the Company maintained
for such purpose in The City of New York, or at such other office or agency of
the Company as may be maintained for such purpose pursuant to SECTION 2.3;
PROVIDED, HOWEVER, that, at the option of the Company, each installment of
interest may be paid by (i) check mailed to addresses of the Persons entitled
thereto as such addresses shall appear on the Note Register or (ii) wire
transfer to an account located in the United States maintained by the payee.
Payments in respect of Securities represented by a Global Security (including
principal, premium and interest) will be made by wire transfer of immediately
available funds to the accounts specified by DTC.

            The Securities may have notations, legends or endorsements required
by law, stock exchange rule or usage, in addition to those set forth on EXHIBIT
A and EXHIBIT B and in SECTION 2.1(d). The Company and the Trustee shall approve
the forms of the Securities and any notation, endorsement or legend on them.
Each Security shall be dated the date of its authentication. The terms of the
Securities set forth in EXHIBIT A and EXHIBIT B are part of the terms of this
Indenture and, to the extent applicable, the Company and the Trustee, by their
execution and delivery of this Indenture, expressly agree to be bound by such
terms.

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

            (d) RESTRICTIVE LEGENDS. Unless and until (i) an Initial Security is

                                                                              46

do so pursuant to any applicable law or regulation, beneficial owners may obtain
Definitive Securities in exchange for their beneficial interests in a Global
Security upon written request in accordance with DTC's and the Registrar's
procedures. In addition, Definitive Securities shall be transferred to all
beneficial owners in exchange for their beneficial interests in a Global
Security if (a) DTC notifies the Company that it is unwilling or unable to
continue as depositary for such Global Security or DTC ceases to be a clearing
agency registered under the Exchange Act, at a time when DTC is required to be
so registered in order to act as depositary, and in each case a successor
depositary is not appointed by the Company within 90 days of such notice or, (b)
the Company in its sole discretion executes and delivers to the Trustee and
Registrar an Officers' Certificate stating that such Global Security shall be so
exchangeable or (c) an Event of Default has occurred and is continuing and the
Registrar has received a request from DTC.

            (ii) Any Definitive Security delivered in exchange for an interest
in a Global Security pursuant to SECTION 2.1(e)(iv) or (v) shall, except as
otherwise provided by SECTION 2.6(c), bear the applicable legend regarding
transfer restrictions applicable to the Definitive Security set forth in SECTION
2.1(d).

            (iii) In connection with the exchange of a portion of a Definitive
Security for a beneficial interest in a Global Security, the Trustee shall
cancel such Definitive Security, and the Company shall execute, and the Trustee
shall authenticate and deliver, to the transferring Holder a new Definitive
Security representing the principal amount not so transferred.

            SECTION 2.2. EXECUTION AND AUTHENTICATION. One Officer shall sign
the Securities for the Company by manual or facsimile signature. If an Officer
whose signature is on a Security no longer holds that office at the time the
Trustee authenticates the Security, the Security shall be valid nevertheless.

            A Security shall not be valid until an authorized signatory of the
Trustee manually authenticates the Security. The signature of the Trustee on a
Security shall be conclusive evidence that such Security has been duly and
validly authenticated and issued under this Indenture. A Security shall be dated
the date of its authentication.

            At any time and from time to time after the execution and delivery
of this Indenture, the Trustee shall authenticate and make available for
delivery: (1) Initial Securities for original issue on the Issue Date in an
aggregate principal amount of $180,000,000, (2) Additional Securities for
original issue in an unlimited principal amount and (3) Exchange Securities for
issue only in an Exchange Offer pursuant to the Registration Rights Agreement,
and only in exchange for Initial Securities or Additional Securities of an equal
principal amount, in each case upon a written order of the Company signed by two
Officers or by an Officer and either an Assistant Treasurer or an Assistant
Secretary of the Company (the "COMPANY ORDER"). Such Company Order shall specify
the amount of the Securities to be authenticated and the date on which the
original issue of Securities is to be authenticated and whether the Securities
are to be Initial Securities, Additional Securities or Exchange Securities.

            The Trustee may appoint an agent (the "AUTHENTICATING AGENT")
reasonably acceptable to the Company to authenticate the Securities. Any such
instrument shall be evidenced by an instrument signed by a Trust Officer, a copy
of which shall be furnished to the

<Page>

                                                                              47

Company. Unless limited by the terms of such appointment, any such
Authenticating Agent may authenticate Securities whenever the Trustee may do so.
Each reference in this Indenture to authentication by the Trustee includes
authentication by the Authenticating Agent.

            In case the Company or any Guarantor, pursuant to ARTICLE IV or
SECTION 11.2, shall be consolidated or merged with or into any other Person or
shall convey, transfer, lease or otherwise dispose of its properties and assets
substantially as an entirety to any Person, and the successor Person resulting
from such consolidation, or surviving such merger, or into which the Company or
any Guarantor shall have been merged, or the Person which shall have received a
conveyance, transfer, lease or other disposition as aforesaid, shall have
executed an indenture supplemental hereto with the Trustee pursuant to ARTICLE
IV, any of the Securities authenticated or delivered prior to such
consolidation, merger, conveyance, transfer, lease or other disposition may,
from time to time, at the request of the successor Person, be exchanged for
other Securities executed in the name of the successor Person with such changes
in phraseology and form as may be appropriate, but otherwise in substance of
like tenor as the Securities surrendered for such exchange and of like principal
amount; and the Trustee, upon Company Order of the successor Person, shall
authenticate and deliver Securities as specified in such order for the purpose
of such exchange. If Securities shall at any time be authenticated and delivered
in any new name of a successor Person pursuant to this SECTION 2.2 in exchange
or substitution for or upon registration of transfer of any Securities, such
successor Person, at the option of the Holders but without expense to them,
shall provide for the exchange of all Securities at the time outstanding for
Securities authenticated and delivered in such new name.

            SECTION 2.3. REGISTRAR AND PAYING AGENT. The Company shall maintain
an office or agency where Securities may be presented for registration of
transfer or for exchange (the "REGISTRAR") and an office or agency where
Securities may be presented for payment (the "PAYING AGENT"). The Company shall
cause each of the Registrar and the Paying Agent to maintain an office or agency
in the Borough of Manhattan, The City of New York. The Registrar shall keep a
register of the Securities and of their transfer and exchange (the "NOTE
REGISTER"). The Company may have one or more co-registrars and one or more
additional paying agents. The term "Paying Agent" includes any additional paying
agent and the term "Registrar" includes any co-registrar.

            The Company shall enter into an appropriate agency agreement with
any Registrar or Paying Agent not a party to this Indenture, which shall
incorporate the terms of the TIA. The agreement shall implement the provisions
of this Indenture that relate to such agent. The Company shall notify the
Trustee of the name and address of each such agent. If the Company fails to
maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be
entitled to appropriate compensation therefor pursuant to SECTION 7.7. The
Company or any of its Restricted Subsidiaries may act as Paying Agent, Registrar
or transfer agent.

            The Company initially appoints the Trustee as Registrar and Paying
Agent for the Securities. The Company may remove any Registrar or Paying Agent
upon written notice to such Registrar or Paying Agent and to the Trustee;
PROVIDED, HOWEVER, that no such removal shall become effective until (i)
acceptance of any appointment by a successor as evidenced by an appropriate
agreement entered into by the Company and such successor Registrar or Paying
Agent, as the case may be, and delivered to the Trustee or (ii) notification to
the Trustee that the

<Page>

                                                                              48

Trustee shall serve as Registrar or Paying Agent until the appointment of a
successor in accordance with clause (i) above. The Registrar or Paying Agent may
resign at any time upon written notice to the Company and the Trustee.

            SECTION 2.4. PAYING AGENT TO HOLD MONEY IN TRUST. By no later than
10:00 a.m. (New York City time) on the date on which any principal of or
interest on any Security is due and payable, the Company shall deposit with the
Paying Agent a sum sufficient in immediately available funds to pay such
principal or interest when due. The Company shall require each Paying Agent
(other than the Trustee) to agree in writing that such Paying Agent shall hold
in trust for the benefit of Securityholders or the Trustee all money held by
such Paying Agent for the payment of principal of or interest on the Securities
and shall notify the Trustee in writing of any default by the Company or any
Guarantor in making any such payment. If the Company or a Subsidiary acts as
Paying Agent, it shall segregate the money held by it as Paying Agent and hold
it as a separate trust fund. The Company at any time may require a Paying Agent
(other than the Trustee) to pay all money held by it to the Trustee and to
account for any funds disbursed by such Paying Agent. Upon complying with this
Section, the Paying Agent (if other than the Company or a Subsidiary) shall have
no further liability for the money delivered to the Trustee. Upon any
bankruptcy, reorganization or similar proceeding with respect to the Company,
the Trustee shall serve as Paying Agent for the Securities.

            SECTION 2.5. SECURITYHOLDER LISTS. The Trustee shall preserve in as
current a form as is reasonably practicable the most recent list available to it
of the names and addresses of Securityholders. If the Trustee is not the
Registrar, or to the extent otherwise required under the TIA, the Company shall
furnish or cause the Registrar to furnish to the Trustee, in writing at least
five Business Days before each interest payment date and at such other times as
the Trustee may request in writing, a list in such form and as of such date as
the Trustee may reasonably require of the names and addresses of
Securityholders.

            SECTION 2.6. TRANSFER AND EXCHANGE.

            (a) The following provisions shall apply with respect to any
proposed transfer of a Rule 144A Note or an Institutional Accredited Investor
Note prior to the date which is two years after the later of the date of its
original issue and the last date on which the Company or any affiliate of the
Company was the owner of such Securities (or any predecessor thereto) (the
"RESALE RESTRICTION TERMINATION DATE"):

            (i) a transfer of a Rule 144A Note or an Institutional Accredited
     Investor Note or a beneficial interest therein to a QIB shall be made upon
     the representation of the transferee in the form as set forth on the

     account with respect to which it exercises sole investment discretion and
     that it and any such account is a "qualified institutional buyer" within
     the meaning of Rule 144A, and is aware that the sale to it is being made in
     reliance on Rule 144A and acknowledges that it has received such
     information regarding the Company as the undersigned has requested pursuant
     to Rule 144A or has determined not to request such information and that it
     is aware that the transferor is relying upon its foregoing representations
     in order to claim the exemption from registration provided by Rule 144A;

     144A and acknowledges that it has received such information regarding the
     Company as the undersigned has requested pursuant to Rule 144A or has
     determined not to request such information and that it is aware that the

            (d) The Registrar shall retain copies of all letters, notices and
other written communications received pursuant to SECTION 2.1 or this SECTION
2.6. The Company shall have the right to inspect and make copies of all such
letters, notices or other written communications at any reasonable time upon the

Dear Sirs:

principal amount of the 11 7/8% Senior Subordinated Notes due 2012 (the
"SECURITIES") of MedQuest, Inc. (the "COMPANY").

            Upon transfer, the Securities would be registered in the name of the
new beneficial owner as follows:

            Name: ___________________________________

            Address: ________________________________

            Taxpayer ID Number: _____________________

            The undersigned represents and warrants to you that:

            1.       We are an institutional "accredited investor" (as defined
in Rule 501(a)(1), (2), (3) or (7) under the Securities Act of 1933, as amended
(the "SECURITIES ACT")) purchasing for our own account or for the account of
such an institutional "accredited investor" at least $250,000 principal amount
of the Securities, and we are acquiring the Securities not with a view to, or
for offer or sale in connection with, any distribution in violation of the
Securities Act. We

<Page>

                                                                              53

have such knowledge and experience in financial and business matters as to be
capable of evaluating the merits and risk of our investment in the Securities
and we invest in or purchase securities similar to the Securities in the normal
course of our business. We and any accounts for which we are acting are each
able to bear the economic risk of our or its investment.

            2.       We understand that the Securities have not been registered
under the Securities Act and, unless so registered, may not be sold except as
permitted in the following sentence. We agree on our own behalf and on behalf of
any investor account for which we are purchasing Securities to offer, sell or
otherwise transfer such Securities prior to the date that is two years after the
later of the date of original issue and the last date on which the Company or
any affiliate of the Company was the owner of such Securities (or any
predecessor thereto) (the "RESALE RESTRICTION TERMINATION DATE") only (a) to the
Company, (b) pursuant to a registration statement which has been declared
effective under the Securities Act, (c) in a transaction complying with the
requirements of Rule 144A under the Securities Act, to a person we reasonably
believe is a qualified institutional buyer under Rule 144A (a "QIB") that
purchases for its own account or for the account of a QIB and to whom notice is
given that the transfer is being made in reliance on Rule 144A, (d) pursuant to
offers and sales that occur outside the United States within the meaning of
Regulation S under the Securities Act, (e) to an institutional "accredited
investor" within the meaning of Rule 501(a)(1), (2), (3) or (7) under the
Securities Act that is purchasing for its own account or for the account of such
an institutional "accredited investor," in each case in a minimum principal
amount of Securities of $250,000 or (f) pursuant to any other available
exemption from the registration requirements of the Securities Act, subject in
each of the foregoing cases to any requirement of law that the disposition of
our property or the property of such investor account or accounts be at all
times within our or their control and in compliance with any applicable state
securities laws. The foregoing restrictions on resale will not apply subsequent
to the Resale Restriction Termination Date. If any resale or other transfer of
the Securities is proposed to be made pursuant to clause (e) above prior to the
Resale Restriction Termination Date, the transferor shall deliver a letter from
the transferee substantially in the form of this letter to the Company and the
Trustee, which shall provide, among other things, that the transferee is an
institutional "accredited investor" (within the meaning of Rule 501(a)(1), (2),
(3) or (7) under the Securities Act) and that it is acquiring such Securities
for investment purposes and not for distribution in violation of the Securities
Act. Each purchaser acknowledges that the Company and the Trustee reserve the
right prior to any offer, sale or other transfer prior to the Resale Termination
Date of the Securities pursuant to clauses (d), (e) or (f) above to require the
delivery of an opinion of counsel, certifications and/or other information
satisfactory to the Company and the Trustee.

            (a)      the offer of the Securities was not made to a person in the
     United States;

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

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

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

            In addition, if the sale is made during a restricted period and the
provisions of Rule 903(c)(3) or Rule 904(c)(1) of Regulation S are applicable
thereto, we confirm that such sale has been made in accordance with the
applicable provisions of Rule 903(c)(3) or Rule 904(c)(1), as the case may be.

            You and the Company are entitled to rely upon this letter and are
irrevocably authorized to produce this letter or a copy hereof to any interested
party in any administrative or legal proceedings or official inquiry with
respect to the matters covered hereby. Terms used in this certificate have the
meanings set forth in Regulation S.

            Very truly yours,

            SECTION 2.10. MUTILATED, DESTROYED, LOST OR STOLEN SECURITIES. If a
mutilated Security is surrendered to the Registrar or if the Holder of a
Security claims that the Security has been lost, destroyed or wrongfully taken,
the Company shall issue and the Trustee shall authenticate a replacement
Security if the requirements of Section 8-405 of the Uniform Commercial Code are
met, such that the Securityholder (a) satisfies the Company or the Trustee
within a reasonable time after such Securityholder has notice of such loss,
destruction or wrongful taking and the Registrar does not register a transfer
prior to receiving such notification, (b) makes such request to the Company or
Trustee prior to the Security being acquired by a protected purchaser as defined
in Section 8-303 of the Uniform Commercial Code (a "protected purchaser") and
(c) satisfies any other reasonable requirements of the Trustee. If required by
the Trustee or the Company, such Holder shall furnish an indemnity bond
sufficient in the judgment of the Company and the Trustee to protect the
Company, the Trustee, the Paying Agent and the Registrar from any loss which any
of them may suffer if a Security is replaced, and, in the absence of notice to
the Company, any Guarantor or the Trustee that such Security has been acquired
by a bona fide purchaser, the Company shall execute and upon Company Order the
Trustee shall authenticate and make available for delivery, in exchange for any
such mutilated Security or in lieu of any such destroyed, lost or stolen
Security, a new Security of like tenor and principal amount, bearing a number
not contemporaneously outstanding.

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

            Upon the issuance of any new Security under this Section, the
Company may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) in connection
therewith.

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

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

                                                                              56

            SECTION 2.11. OUTSTANDING SECURITIES. Securities outstanding at any
time are all Securities authenticated by the Trustee except for those cancelled
by it, those delivered to it for cancellation and those described in this
Section as not outstanding. A Security does not cease to be outstanding in the
event the Company or a Subsidiary of the Company holds the Security, PROVIDED,
HOWEVER, that (i) for purposes of determining which are outstanding for consent
or voting purposes hereunder, the provisions of SECTION 13.6 shall apply and
(ii) in determining whether the Trustee shall be protected in making a
determination whether the Holders of the requisite principal amount of
outstanding Securities are present at a meeting of Holders of Securities for
quorum purposes or have consented to or voted in favor of any request, demand,
authorization, direction, notice, consent, waiver, amendment or modification
hereunder, or relying upon any such quorum, consent or vote, only Securities
which a Trust Officer of the Trustee actually knows to be held by the Company or
an Affiliate of the Company shall not be considered outstanding.

            If a Security is replaced pursuant to SECTION 2.10, it ceases to be
outstanding unless the Trustee and the Company receive proof satisfactory to
them that the replaced Security is held by a bona fide purchaser.

            If the Paying Agent segregates and holds in trust, in accordance
with this Indenture, on a redemption date or maturity date money sufficient to
pay all principal and interest payable on that date with respect to the
Securities (or portions thereof) to be redeemed or maturing, as the case may be,
and the Paying Agent is not prohibited from paying such money to the
Securityholders on that date pursuant to the terms of this Indenture, then on
and after that date such Securities (or portions thereof) cease to be
outstanding and interest on them ceases to accrue.

            SECTION 2.12. TEMPORARY SECURITIES. In the event that Definitive
Securities are to be issued under the terms of this Indenture, until such
Definitive Securities are ready for delivery, the Company may prepare and the
Trustee shall authenticate temporary Securities. Temporary Securities shall be
substantially in the form of Definitive Securities but may have variations that
the Company considers appropriate for temporary Securities. Without unreasonable
delay, the Company shall prepare and the Trustee shall authenticate Definitive
Securities. After the preparation of Definitive Securities, the temporary
Securities shall be exchangeable for Definitive Securities upon surrender of the
temporary Securities at any office or agency maintained by the Company for that
purpose and such exchange shall be without charge to the Holder. Upon surrender
for cancellation of any one or more temporary Securities, the Company shall
execute, and the Trustee shall authenticate and make available for delivery in
exchange therefor, one or more Definitive Securities representing an equal
principal amount of Securities. Until so exchanged, the Holder of temporary
Securities shall in all respects be entitled to the same benefits under this
Indenture as a Holder of Definitive Securities.

            SECTION 2.13. CANCELLATION. The Company at any time may deliver
Securities to the Trustee for cancellation. The Registrar and the Paying Agent
shall forward to the Trustee any Securities surrendered to them for registration
of transfer, exchange or payment. The Trustee and no one else shall cancel all
Securities surrendered for registration of transfer, exchange, payment or
cancellation and destroy such Securities in accordance with its internal
policies including delivery of a certificate (a "CERTIFICATE OF DESTRUCTION")
describing such

<Page>

                                                                              57

Securities disposed (subject to the record retention requirements of the
Exchange Act). The Company may not issue new Securities to replace Securities it
has paid or delivered to the Trustee for cancellation for any reason other than
in connection with a transfer or exchange.

            SECTION 2.14. PAYMENT OF INTEREST; DEFAULTED INTEREST. Interest on
any Security which is payable, and is punctually paid or duly provided for, on
any interest payment date shall be paid to the Person in whose name such
Security (or one or more predecessor Securities) is registered at the close of
business on the regular record date for such interest at the office or agency of
the Company maintained for such purpose pursuant to SECTION 2.3.

            Any interest on any Security which is payable, but is not paid when
the same becomes due and payable and such nonpayment continues for a period of
30 days shall forthwith cease to be payable to the Holder on the regular record
date by virtue of having been such Holder, and such defaulted interest and (to
the extent lawful) interest on such defaulted interest at the rate borne by the
Securities (such defaulted interest and interest thereon herein collectively
called "DEFAULTED INTEREST") shall be paid by the Company, at its election in
each case, as provided in clause (a) or (b) below:

            (a) The Company may elect to make payment of any Defaulted Interest
     to the Persons in whose names the Securities (or their respective
     predecessor Securities) are registered at the close of business on a
     Special Record Date (as defined below) for the payment of such Defaulted
     Interest, which shall be fixed in the following manner. The Company shall
     notify the Trustee in writing of the amount of Defaulted Interest proposed
     to be paid on each Security and the date (not less than 30 days after such
     notice) of the proposed payment (the "SPECIAL INTEREST PAYMENT DATE"), and
     at the same time the Company shall deposit with the Trustee an amount of
     money equal to the aggregate amount proposed to be paid in respect of such
     Defaulted Interest or shall make arrangements satisfactory to the Trustee
     for such deposit prior to the date of the proposed payment, such money when
     deposited to be held in trust for the benefit of the Persons entitled to
     such Defaulted Interest as in this clause provided. Thereupon the Trustee
     shall fix a record date (the "SPECIAL RECORD DATE") for the payment of such
     Defaulted Interest, which date shall be not more than 15 days and not less
     than 10 days prior to the Special Interest Payment Date and not less than
     10 days after the receipt by the Trustee of the notice of the proposed
     payment. The Trustee shall promptly notify the Company of such Special
     Record Date, and in the name and at the expense of the Company, shall cause
     notice of the proposed payment of such Defaulted Interest and the Special
     Record Date and Special Interest Payment Date therefor to be given in the
     manner provided for in SECTION 13.2, not less than 10 days prior to such
     Special Record Date. Notice of the proposed payment of such Defaulted
     Interest and the Special Record Date and Special Interest Payment Date
     therefor having been so given, such Defaulted Interest shall be paid on the
     Special Interest Payment Date to the Persons in whose names the Securities
     (or their respective predecessor Securities) are registered at the close of
     business on such Special Record Date and shall no longer be payable
     pursuant to the following clause (b).

            (b) The Company may make payment of any Defaulted Interest in any
     other lawful manner not inconsistent with the requirements of any
     securities exchange on which the Securities may be listed, and upon such
     notice as may be required by such

<Page>

                                                                              58

     exchange, if, after notice given by the Company to the Trustee of the
     proposed payment pursuant to this clause, such manner of payment shall be
     deemed practicable by the Trustee.

            Subject to the foregoing provisions of this Section, each Security
delivered under this Indenture upon registration of, transfer of or in exchange
for or in lieu of any other Security shall carry the rights to interest accrued
and unpaid, and to accrue, which were carried by such other Security.

            SECTION 2.15. COMPUTATION OF INTEREST. Interest on the Securities
shall be computed on the basis of a 360-day year of twelve 30-day months.

            SECTION 2.16. CUSIP AND ISIN NUMBERS. The Company in issuing the
Securities may use "CUSIP" and "ISIN" numbers (if then generally in use) and, if
so, the Trustee shall use "CUSIP" and "ISIN" numbers in notices of redemption as
a convenience to Holders; PROVIDED, HOWEVER, that any such notice may state that
no representation is made as to the correctness of such numbers either as
printed on the Securities or as contained in any notice of a redemption and that
reliance may be placed only on the other identification numbers printed on the
Securities, and any such redemption shall not be affected by any defect in or
omission of such CUSIP or ISIN numbers. The Company shall promptly notify the
Trustee in writing of any change in the CUSIP and ISIN numbers.

                                   ARTICLE III

                                    COVENANTS

            SECTION 3.1. PAYMENT OF SECURITIES. The Company shall promptly pay
the principal of and interest on the Securities on the dates and in the manner
provided in the Securities and in this Indenture. Principal and interest shall
be considered paid on the date due if on such date the Trustee or the Paying
Agent holds in accordance with this Indenture immediately available funds
sufficient to pay all principal and interest then due and the Trustee or the
Paying Agent, as the case may be, is not prohibited from paying such money to
the Securityholders on that date pursuant to the terms of this Indenture.

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

            Notwithstanding anything to the contrary contained in this
Indenture, the Company may, to the extent it is required to do so by law, deduct
or withhold income or other similar taxes imposed by the United States of
America from principal or interest payments hereunder.

            SECTION 3.2. SEC REPORTS. Notwithstanding that the Company may not
be subject to the reporting requirements of Section 13 or 15(d) of the Exchange
Act, to the extent permitted by the Exchange Act, the Company shall file with
the SEC, and make available to the Trustee and the registered Holders of the
Securities, the annual reports and the information,

<Page>

                                                                              59

documents and other reports (or copies of such portions of any of the foregoing
as the SEC may by rules and regulations prescribe) that are specified in
Sections 13 and 15(d) of the Exchange Act within the time periods specified
therein. In the event that the Company is not permitted to file such reports,
documents and information with the SEC pursuant to the Exchange Act, the Company
will nevertheless make available such Exchange Act information to the Trustee
and the Holders of the Securities as if the Company were subject to the
reporting requirements of Section 13 or 15(d) of the Exchange Act within the
time periods specified therein.

            If the Unrestricted Subsidiaries of the Company, either individually
or in the aggregate, would constitute a Significant Subsidiary (if such
Subsidiaries were Restricted Subsidiaries), then the quarterly and annual
reports referred to in the preceding paragraph shall include a Management's
Discussion and Analysis of Results of Operations and Financial Condition that
describes, for the relevant period, the financial performance of the Company and
its Restricted Subsidiaries.

            Notwithstanding the foregoing, so long as Holdings is a Guarantor,
the reports, documents and information required to be filed and provided as
described above may be those of Holdings, rather than the Company, so long as
such filings would satisfy the requirements of the Exchange Act and regulations
promulgated thereunder.

            SECTION 3.3. LIMITATION ON INDEBTEDNESS. (a) The Company shall not,
and shall not permit any of its Restricted Subsidiaries to, Incur any
Indebtedness (including Acquired Indebtedness); PROVIDED, HOWEVER, that the
Company and the Subsidiary Guarantors may Incur Indebtedness if on the date
thereof:

            (1)      the Consolidated Coverage Ratio for the Company and its
                     Restricted Subsidiaries is at least 2.00 to 1.00; and

            (2)      no Default or Event of Default will have occurred or be
                     continuing or would occur as a consequence of Incurring the
                     Indebtedness.

     (b)    SECTION 3.3(a) will not prohibit the Incurrence of the following
            Indebtedness:

            (1)      Indebtedness of the Company or the Subsidiary Guarantors
                     Incurred pursuant to the Senior Credit Agreement in an
                     aggregate amount up to $95.0 million less the aggregate
                     principal amount of permanent commitment reductions with
                     the proceeds from Asset Dispositions;

            (2)      the Notes Guarantees and any other Guarantees by the
                     Subsidiary Guarantors of Indebtedness Incurred in
                     accordance with the provisions of this Indenture; PROVIDED
                     that in the event such Indebtedness that is being
                     Guaranteed is (a) Senior Subordinated Indebtedness or
                     Guarantor Senior Subordinated Indebtedness, then the
                     related Guarantee shall rank equally in right of payment to
                     the Notes Guarantees hereunder or (b) a Subordinated
                     Obligation or a Guarantor Subordinated Obligation, then the
                     related Guarantee shall be subordinated in right of payment
                     to the Notes Guarantee;

<Page>

                                                                              60

            (3)      Indebtedness of the Company owing to and held by any
                     Restricted Subsidiary (other than a Receivables Entity) or
                     Indebtedness of a Restricted Subsidiary owing to and held
                     by the Company or any Restricted Subsidiary (other than a
                     Receivables Entity), PROVIDED, HOWEVER;

                     (a)    if the Company is the obligor on such Indebtedness,
                            such Indebtedness is expressly subordinated to the
                            prior payment in full in cash of all obligations
                            with respect to the Securities;

                     (b)    if a Subsidiary Guarantor is the obligor on such
                            Indebtedness and the Company is not the Obligee,
                            such Indebtedness is subordinated in right of
                            payment to the Notes Guarantees of such Subsidiary
                            Guarantor; and

                     (c)    (i) any subsequent issuance or transfer of Capital
                            Stock or any other event which results in any such
                            Indebtedness being beneficially held by a Person
                            other than the Company or a Restricted Subsidiary
                            (other than a Receivables Entity) of the Company;
                            and

                            (ii) any sale or other transfer of any such
                            Indebtedness to a Person other than the Company or a
                            Restricted Subsidiary (other than a Receivables
                            Entity) of the Company,

                     shall be deemed, in each case, to constitute an Incurrence
                     of such Indebtedness by the Company or such Subsidiary, as
                     the case may be;

            (4)      Indebtedness represented by (a) the Securities issued on
                     the Issue Date and the Exchange Securities issued in
                     exchange therefor in a registered exchange offer pursuant
                     to the Registration Rights Agreement, (b) any Indebtedness
                     (other than the Indebtedness described in clauses (1), (2),
                     (3), (5), (7), (8), (9) and (10)) outstanding on the Issue
                     Date and (c) any Refinancing Indebtedness Incurred in
                     respect of any Indebtedness described in this clause (4) or
                     Incurred pursuant to SECTION 3.3(a);

            (5)      Indebtedness under Currency Agreements and Interest Rate
                     Agreements; PROVIDED that in the case of Currency
                     Agreements, such Currency Agreements are related to
                     business transactions of the Company or its Restricted
                     Subsidiaries entered into in the ordinary course of
                     business or in the case of Currency Agreements and Interest
                     Rate Agreements, such Currency Agreements and Interest Rate
                     Agreements are entered into for bona fide hedging purposes
                     of the Company or its Restricted Subsidiaries (as
                     determined in good faith by the Board of Directors or
                     senior management of the Company) and substantially
                     correspond in terms of notional amount, duration,
                     currencies and interest rates, as applicable, to
                     Indebtedness of the Company or its Restricted Subsidiaries
                     Incurred without violation of this Indenture;

<Page>

                                                                              61

            (6)      Indebtedness (including Capitalized Lease Obligations and
                     Acquired Indebtedness) Incurred by the Company or any of
                     the Subsidiary Guarantors to finance the acquisition,
                     purchase, lease, construction, development, maintenance,
                     upgrade or improvement, in each case, to the extent such
                     expenditures are capitalized on the balance sheet of the
                     Company, of property (real or personal), equipment or other
                     assets (in each case whether through the direct purchase of
                     assets or the Capital Stock of any Person owning such
                     assets) so long as such Indebtedness is created within six
                     months of the acquisition, purchase, lease, construction,
                     development, maintenance, upgrade or improvement of the
                     related asset; PROVIDED that the aggregate principal amount
                     of all Indebtedness Incurred pursuant to this clause (6)
                     and all Refinancing Indebtedness to refund, refinance or

                     Company or a Restricted Subsidiary in the ordinary course
                     of business;

            (8)      Indebtedness arising from agreements of the Company or a

                     each case, Incurred or assumed in connection with the
                     disposition of any business, assets or Capital Stock of a
                     Restricted Subsidiary in accordance with the terms of this
                     Indenture, other than Guarantees by the Company or any
                     Restricted Subsidiary of Indebtedness Incurred by any
                     Person acquiring all or any portion of such business,
                     assets or a Subsidiary of the Company for the purpose of
                     financing such acquisition, PROVIDED that the maximum
                     aggregate liability in respect of all such Indebtedness
                     shall at no time exceed the gross proceeds, including the
                     fair market value as determined in good faith by a majority
                     of the Board of Directors of noncash proceeds (the fair
                     market value of such noncash proceeds being measured at the
                     time it is received and without giving effect to any
                     subsequent changes in value) actually received by the
                     Company and its Restricted Subsidiaries in connection with
                     such disposition;

            (9)      Indebtedness arising from the honoring by a bank or other

                     business, PROVIDED, HOWEVER, that such Indebtedness is
                     extinguished within five Business Days of Incurrence;

                     Restricted Subsidiary of the Company (except for Standard
                     Securitization Undertakings); and

            (11)     in addition to the items referred to in clauses (1) through
                     (10) above, Indebtedness of the Company and its Subsidiary
                     Guarantors in an aggregate outstanding principal amount
                     which, when taken together with the principal amount of all
                     other Indebtedness Incurred pursuant to this clause (11)
                     and then outstanding, will not exceed $25.0 million at any
                     one time outstanding.

     (c)    The Company will not Incur any Indebtedness under SECTION 3.3(b) if
the proceeds thereof are used, directly or indirectly, to refinance any
Subordinated Obligations of the Company unless such Indebtedness will be
subordinated to the Securities to at least the same extent as such Subordinated
Obligations. No Guarantor will Incur any indebtedness if the proceeds thereof
are used, directly or indirectly, to refinance any Guarantor Subordinated
Obligations of such Guarantor unless such Indebtedness will be subordinated to
the obligations of such Guarantor under its Notes Guarantee to at least the same
extent as such Guarantor Subordinated Obligations. No Restricted Subsidiary that
is not a Subsidiary Guarantor may Incur any Indebtedness if the proceeds are
used to refinance Indebtedness of the Company.

     (d)    For purposes of determining compliance with, and the outstanding
principal amount of any particular Indebtedness Incurred pursuant to and in
compliance with, this SECTION 3.3:

            (1)      in the event that Indebtedness meets the criteria of more
                     than one of the types of Indebtedness described in SECTION
                     3.3(a) OR (b), the Company, in its sole discretion, will
                     classify such item of Indebtedness on the date of
                     Incurrence and only be required to include the amount and
                     type of such Indebtedness in the clause so selected, except
                     that, following the date of Incurrence, the Company may
                     later reclassify all or a portion of such item of
                     Indebtedness in any manner that complies with this SECTION
                     3.3; PROVIDED that the Indebtedness so reclassified is of
                     the nature referred to in the clause into which all or a
                     portion of such Indebtedness is reclassified;

            (2)      all Indebtedness outstanding on the date of this Indenture
                     under the Senior Credit Agreement shall be deemed initially
                     Incurred on the Issue Date under clause (1) of SECTION
                     3.3(b) and not clause (4) of SECTION 3.3(b);

            (3)      Guarantees of, or obligations in respect of letters of
                     credit relating to, Indebtedness which is otherwise
                     included in the determination of a particular amount of
                     Indebtedness shall not be included;

            (4)      if obligations in respect of letters of credit are Incurred
                     pursuant to the Senior Credit Agreement and are being
                     treated as Incurred pursuant to clause (1) of SECTION
                     3.3(b) and the letters of credit relate to other
                     Indebtedness, then such other Indebtedness shall not be
                     included;

                                                                              63

            (5)      the principal amount of any Disqualified Stock of the
                     Company or a Restricted Subsidiary or Preferred Stock of a
                     Restricted Subsidiary that is not a Guarantor will be equal
                     to the greater of the maximum mandatory redemption or
                     repurchase price (not including, in either case, any
                     redemption or repurchase premium) or the liquidation
                     preference thereof;

            (6)      Indebtedness permitted by this SECTION 3.3 need not be
                     permitted solely by reference to one provision permitting
                     such Indebtedness but may be permitted in part by one such
                     provision and in part by one or more other provisions of
                     this SECTION 3.3 permitting such Indebtedness; and

            (7)      the amount of Indebtedness issued at a price that is less
                     than the principal amount thereof will be equal to the
                     amount of the liability in respect thereof determined in
                     accordance with GAAP.

            Accrual of interest, accrual of dividends, the accretion of accreted
value, the payment of interest in the form of additional Indebtedness and the
payment of dividends in the form of additional shares of Preferred Stock or
Disqualified Stock will not be deemed to be an Incurrence of Indebtedness for
purposes of this SECTION 3.3.

     (e)    In addition, the Company will not permit any of its Unrestricted
Subsidiaries to Incur any Indebtedness or issue any shares of Disqualified
Stock, other than Non-Recourse Debt. If at any time an Unrestricted Subsidiary
becomes a Restricted Subsidiary, any Indebtedness of such Subsidiary shall be
deemed to be Incurred by a Restricted Subsidiary of the Company as of such date
(and, if such Indebtedness is not permitted to be Incurred as of such date under
this SECTION 3.3, the Company shall be in Default of this SECTION 3.3).

     (f)    For purposes of determining compliance with any U.S.
dollar-denominated restriction on the Incurrence of Indebtedness, the U.S.
dollar-equivalent principal amount of Indebtedness denominated in a foreign
currency shall be calculated based on the relevant currency exchange rate in
effect on the date such Indebtedness was Incurred, in the case of term
Indebtedness, or first committed, in the case of revolving credit Indebtedness;
PROVIDED that if such Indebtedness is Incurred to refinance other Indebtedness
denominated in a foreign currency, and such refinancing would cause the
applicable U.S. dollar-denominated restriction to be exceeded if calculated at
the relevant currency exchange rate in effect on the date of such refinancing,
such U.S. dollar-denominated restriction shall be deemed not to have been
exceeded so long as the principal amount of such refinancing Indebtedness does
not exceed the principal amount of such Indebtedness being refinanced.
Notwithstanding any other provision of this SECTION 3.3, the maximum amount of
Indebtedness that the Company may Incur pursuant to this SECTION 3.3 shall not
be deemed to be exceeded solely as a result of fluctuations in the exchange rate
of currencies. The principal amount of any Indebtedness Incurred to refinance
other Indebtedness, if Incurred in a different currency from the Indebtedness
being refinanced, shall be calculated based on the currency exchange rate
applicable to the currencies in which such Refinancing Indebtedness is
denominated that is in effect on the date of such refinancing.

     SECTION 3.4. LIMITATION ON RESTRICTED PAYMENTS. (a) The Company shall not,
and shall not permit any of its Restricted Subsidiaries, directly or indirectly,

                            options, warrants or other rights to purchase such
                            Capital Stock; and

                     (b)    dividends or distributions payable to the Company or
                            a Restricted Subsidiary of the Company or to other
                            holders of Common Stock of a Restricted Subsidiary
                            on a pro rata basis;

            (2)      purchase, redeem, retire or otherwise acquire for value any
                     Capital Stock of the Company or any direct or indirect
                     parent of the Company held by Persons other than the
                     Company or a Restricted Subsidiary of the Company;

            (3)      purchase, repurchase, redeem, defease or otherwise acquire
                     or retire for value, prior to scheduled maturity, scheduled
                     repayment or scheduled sinking fund payment, any
                     Subordinated Obligations or Guarantor Subordinated
                     Obligations (other than the purchase, repurchase,
                     redemption, defeasance or other acquisition or retirement
                     of Subordinated Obligations or Guarantor Subordinated
                     Obligations purchased in anticipation of satisfying a
                     sinking fund obligation, principal installment or final
                     maturity, in each case due within one year of the date of
                     purchase, repurchase, redemption, defeasance or other
                     acquisition or retirement); or

            (4)      make any Restricted Investment in any Person;

(any such dividend, distribution, purchase, redemption, repurchase, defeasance,
other acquisition, retirement or Restricted Investment referred to in clauses
(1) through (4) shall be referred to herein as a "RESTRICTED PAYMENT"), if at
the time the Company or such Restricted Subsidiary makes such Restricted
Payment:

            (a)      a Default shall have occurred and be continuing (or would
                     result therefrom); or

            (b)      the Company is not able to Incur an additional $1.00 of
                     Indebtedness pursuant to SECTION 3.3(a) after giving
                     effect, on a pro forma basis, to such Restricted Payment;
                     or

            (c)      the aggregate amount of such Restricted Payment and all
                     other Restricted Payments declared or made subsequent to
                     the Issue Date would exceed the sum of:

                            (treated as one accounting period) from July 1, 2002

based upon an opinion or appraisal issued by an accounting, appraisal or
investment banking firm of national standing if such fair market value is
estimated in good faith by the Board of Directors of the Company to exceed $25.0
million. Not later than the date of making any Restricted Payment, the Company

Obligations, Guarantor Senior Subordinated Indebtedness or Guarantor
Subordinated Obligations, unless contemporaneously with the Incurrence of the
Liens effective provision is made to secure the Indebtedness due under this
Indenture and the Securities or, in respect of Liens on any Restricted
Subsidiary's property or assets, any Notes Guarantee of such Restricted
Subsidiary, equally and ratably with (or prior to in the case of Liens with
respect to Subordinated Obligations or Guarantor Subordinated Obligations, as
the case may be) the Indebtedness secured by such Lien for so long as such
Indebtedness is so secured.

                     any Restricted Subsidiary to other Indebtedness Incurred by
                     the Company or any Restricted Subsidiary shall not be
                     deemed a restriction on the ability to make loans or

            (1)      the Company or such Restricted Subsidiary, as the case may
                     be, receives consideration at the time of contractually
                     agreeing to such Asset Disposition at least equal to the
                     fair market value, as determined in good faith by the Board
                     of Directors (including as to the value of all non-cash
                     consideration), of the shares and assets subject to such
                     Asset Disposition;

            (2)      at least 75% of the consideration from such Asset
                     Disposition received by the Company or such Restricted
                     Subsidiary, as the case may be, is in the form of cash or
                     Cash Equivalents; and

            (3)      an amount equal to 100% of the Net Available Cash from such
                     Asset Disposition is applied by the Company or such
                     Restricted Subsidiary, as the case may be:

                     (a)    FIRST, to the extent the Company or any Restricted
                            Subsidiary, as the case may be, elects (or is
                            required by the terms of any Senior Indebtedness),
                            to prepay, repay or purchase Senior Indebtedness or
                            Indebtedness (other than any Disqualified Stock or
                            Guarantor Subordinated Obligation) of a Restricted
                            Subsidiary that is a Subsidiary Guarantor (in each
                            case other than Indebtedness owed to the Company or
                            an Affiliate of the Company) within 365 days from
                            the later of the date of such Asset Disposition or
                            the receipt of such Net Available Cash; PROVIDED,
                            HOWEVER, that, in connection with any prepayment,
                            repayment or purchase of Indebtedness pursuant to
                            this clause (a), the Company or such Restricted
                            Subsidiary will retire such Indebtedness and will
                            cause the related commitment (if any) to be
                            permanently reduced in an amount equal to the
                            principal amount so prepaid, repaid or purchased;
                            and

                     (b)    SECOND, to the extent of the balance of such Net

                                                                              74

                            such Asset Disposition or the receipt of such Net
                            Available Cash; PROVIDED that pending the final
                            application of any such Net Available Cash in
                            accordance with this clause (b) or clause (a) above,
                            the Company and its Restricted Subsidiaries may
                            temporarily reduce Indebtedness or otherwise invest
                            such Net Available Cash in any manner not prohibited
                            by this Indenture.

            (b)      Any Net Available Cash from Asset Dispositions that are not
applied or invested as provided in SECTION 3.7(a) will be deemed to constitute
"EXCESS PROCEEDS." On the 366th day after an Asset Disposition, if the aggregate
amount of Excess Proceeds exceeds $20.0 million, the Company will be required to
make an offer ("ASSET DISPOSITION OFFER") to all Holders of Securities and to
the extent required by the terms of other Senior Subordinated Indebtedness, to
all holders of other Senior Subordinated Indebtedness outstanding with similar
provisions requiring the Company to make an offer to purchase such Senior
Subordinated Indebtedness with the proceeds from any Asset Disposition ("PARI
PASSU NOTES"), to purchase, on a ratable basis, the maximum principal amount of
Securities and any such Pari Passu Notes to which the Asset Disposition Offer
applies that may be purchased out of the Excess Proceeds, at an offer price in
cash in an amount equal to 100% of the principal amount of the Securities and
Pari Passu Notes plus accrued and unpaid interest to the date of purchase, in
accordance with the procedures set forth in this Indenture or the agreements
governing the Pari Passu Notes, as applicable, in each case in integral
multiples of $1,000. To the extent that the aggregate amount of Securities and
Pari Passu Notes so validly tendered and not properly withdrawn pursuant to an
Asset Disposition Offer is less than the Excess Proceeds, the Company may use
any remaining Excess Proceeds for general corporate purposes subject to the
other covenants contained in this Indenture. If the aggregate principal amount
of Securities surrendered by Holders thereof and other Pari Passu Notes
surrendered by holders or lenders, collectively, exceeds the amount of Excess
Proceeds, the Trustee shall select the Securities and Pari Passu Notes to be
purchased on a pro rata basis on the basis of the aggregate principal amount of
tendered Securities and Pari Passu Notes. Upon completion of such Asset
Disposition Offer, the amount of Excess Proceeds shall be reset at zero.

            (c)      (1) The Asset Disposition Offer will remain open for a
period of 20 Business Days following its commencement, except to the extent that
a longer period is required by applicable law (the "ASSET DISPOSITION OFFER
PERIOD"). No later than five Business Days after the termination of the Asset
Disposition Offer Period (the "ASSET DISPOSITION PURCHASE DATE"), the Company
will purchase the principal amount of Securities and Pari Passu Notes required
to be purchased pursuant to this SECTION 3.7 (the "ASSET DISPOSITION OFFER
AMOUNT") or, if less than the Asset Disposition Offer Amount has been so validly
tendered, all Securities and Pari Passu Notes validly tendered in response to
the Asset Disposition Offer.

            (2) If the Asset Disposition Purchase Date is on or after an
interest record date and on or before the related interest payment date, any
accrued and unpaid interest will be paid to the Person in whose name a Security
is registered at the close of business on such record date, and no additional
interest will be payable to Holders of the Securities who tender Securities
pursuant to the Asset Disposition Offer.

            (3) On or before the Asset Disposition Purchase Date, the Company
will, to the extent lawful, accept for payment, on a pro rata basis to the
extent necessary, the Asset Disposition Offer Amount of Securities and Pari
Passu Notes or portions of Securities and Pari Passu Notes so validly tendered
and not properly withdrawn pursuant to the Asset Disposition Offer, or if less
than the Asset Disposition Offer Amount has been validly tendered and not
properly withdrawn, all Securities and Pari Passu Notes so validly tendered and
not properly withdrawn, in each case in integral multiples of $1,000. The
Company will deliver to the Trustee an Officers' Certificate stating that such
Securities or portions thereof were accepted for payment by the Company in
accordance with the terms of this SECTION 3.7 and, in addition, the Company will
deliver all certificates and notes required, if any, by the agreements governing
the Pari Passu Notes. The Company or the Paying Agent, as the case may be, will
promptly (but in any case not later than five Business Days after termination of
the Asset Disposition Offer Period) mail or deliver to each tendering Holder of
Securities or holder or lender of Pari Passu Notes, as the case may be, an
amount equal to the purchase price of the Securities or Pari Passu Notes so
validly tendered and not properly withdrawn by such holder or lender, as the
case may be, and accepted by the Company for purchase, and the Company will
promptly issue a new Security, and the Trustee, upon delivery of an Officers'
Certificate from the Company will authenticate and mail or deliver such new
Security to such Holder, in a principal amount equal to any unpurchased portion
of the Security surrendered; PROVIDED that each such new Security will be in a
principal amount of $1,000 or an integral multiple of $1,000. In addition, the
Company will take any and all other actions required by the agreements governing
the Pari Passu Notes. Any Security not so accepted will be promptly mailed or
delivered by the Company to the Holder thereof. The Company will publicly
announce the results of the Asset Disposition Offer on or prior to the Asset
Disposition Purchase Date.

            For the purposes of this SECTION 3.7, the following will be deemed
to be cash:

            (1)      the assumption by the transferee of Indebtedness (other

                     favorable to the Company or such Restricted Subsidiary, as

                     recognized standing that such Affiliate Transaction is not
                     materially less favorable than those that could reasonably
                     have been obtained in a comparable transaction at such time
                     on an arm's length basis from a Person that is not an

            (2)      the repurchase date (which shall be no earlier than 30 days
                     nor later than 60 days from the date such notice is mailed)

                     this Indenture, that a Holder must follow in order to have

                     Securities or portions of Securities being purchased by the
                     Company.

            The Paying Agent shall promptly mail to each Holder of Securities so
tendered the Change of Control Payment for such Securities, and the Trustee
shall promptly authenticate and mail (or cause to be transferred by book entry)
to each Holder a new Security equal in principal amount to any unpurchased

                     Restricted Subsidiary, any Investment in such Person
                     remaining after giving effect to such issuance or sale

Domestic Restricted Subsidiaries to execute and deliver to the Trustee a
supplemental indenture, in the form set forth as EXHIBIT C to this Indenture,
pursuant to which such Domestic Restricted Subsidiary will unconditionally

office or agency or shall fail to furnish the Trustee with the address thereof,
such presentations, surrenders, notices and demands may be made or served at the
Corporate Trust Office of the Trustee, and the Company hereby appoints the

offices or agencies (in or outside of The City of New York) where the Securities
may be presented or surrendered for any or all such purposes and may from time
to time rescind any such designation; PROVIDED, HOWEVER, that no such
designation or rescission shall in any manner relieve the Company of its
obligation to maintain an office or agency in The City of New York

partnership, limited liability or other existence of each Restricted Subsidiary
and the rights (charter and statutory) licenses and franchises of the Company
and each Restricted Subsidiary; PROVIDED, HOWEVER, that the Company shall not be
required to preserve any such existence (except the Company), right, license or
franchise if the Board of Directors of the Company shall determine that the
preservation thereof is no longer desirable in the conduct of the business of
the Company and each of its Restricted Subsidiaries, taken as a whole, and that
the loss thereof would not have a material adverse effect on the ability of the
Company to perform its obligations under the Securities or this Indenture, and

Restricted Subsidiary; PROVIDED, HOWEVER, that the Company shall not be required
to pay or discharge or cause to be paid or discharged any such tax, assessment,
charge or claim whose amount, applicability or validity is being contested in
good faith by appropriate proceedings and for which appropriate reserves, if
necessary (in the good faith judgment of management of the Company), are being
maintained in accordance with GAAP or where the failure to pay or discharge the
same would not have a material adverse effect on the ability of the Company to
perform its obligations under the Securities or this Indenture.

            SECTION 3.17. PAYMENTS FOR CONSENT. Neither the Company nor any of
its Restricted Subsidiaries shall, directly or indirectly, pay or cause to be
paid any consideration, whether by way of interest, fees or otherwise, to any
Holder of any Securities for or as an inducement to any consent, waiver or
amendment of any of the terms or provisions of this Indenture or the Securities

Securities that consent, waive or agree to amend in the time frame set forth in
the solicitation documents relating to such consent, waiver or amendment.

the Trustee within 120 days after the end of each Fiscal Year of the Company an

Default or default, its status and the action which the Company proposes to take

                     Company as a result of such transaction as having been
                     Incurred by the Successor Company or such Subsidiary at the

            For purposes of this SECTION 4.1, the sale, lease, conveyance,
assignment, transfer, or other disposition of all or substantially all of the
properties and assets of one or more Subsidiaries of the Company, which
properties and assets, if held by the Company instead of such Subsidiaries,

substantially all of the properties and assets of the Company.

            The Successor Company shall succeed to, and be substituted for, and
may exercise every right and power of, the Company under this Indenture, but, in
the case of a lease of all or substantially all its assets, the predecessor
Company will not be released from the obligation to pay the principal of and
interest on the Securities. Solely for the purpose of computing amounts
described in clause (c)(i) of SECTION 3.4(a), the Successor Company shall only
be deemed to have succeeded and be substituted for the Company with respect to
periods subsequent to the effective time of such merger, consolidation,
combination or transfer of assets.

                     supplemental indenture, executed and delivered to the
                     Trustee, in form satisfactory to the Trustee, all the
                     obligations of such Subsidiary Guarantor under its Notes
                     Guarantee;

                (ii) immediately after giving effect to such transaction (and
                     treating any Indebtedness that becomes an obligation of the

                     Subsidiary as a result of such transaction as having been
                     Incurred by such Person or such Restricted Subsidiary at

               (iii) the Company shall have delivered to the Trustee an
                     Officers' Certificate and an Opinion of Counsel, each
                     stating that such consolidation, merger or transfer and
                     such supplemental indenture (if any) comply with the
                     Indenture; or

            (B)      such transaction results in the Company receiving cash or
                     other property (other than Capital Stock representing a
                     controlling interest in the

                     successor entity), and the transaction is made in
                     compliance with the covenant described under Section 3.7.

            In addition, the Company shall not permit Holdings to consolidate
with or merge with or into any Person (other than the Company or another
Guarantor) unless the resulting, surviving or transferee Person will be a
corporation, partnership, trust or limited liability company organized and
existing under the laws of the United States of America, any State of the United
States or the District of Columbia and such Person (if not Holdings) shall
expressly assume, by supplemental indenture, executed and delivered to the
Trustee, in form satisfactory to the Trustee, all the obligations of Holdings
under its Notes Guarantee.

            Notwithstanding the preceding clause (3) of the first sentence of
this SECTION 4.1, (x) any Restricted Subsidiary of the Company (other than a
Receivables Entity) may consolidate with, merge into or transfer all or part of
its properties and assets to the Company or a Subsidiary that is a Guarantor and
(y) the Company may merge with an Affiliate incorporated solely for the purpose
of reincorporating the Company in another jurisdiction to realize tax benefits;
PROVIDED that, in the case of a Restricted Subsidiary that merges into the
Company, the Company shall not be required to comply with the preceding clause
(5).

                            REDEMPTION OF SECURITIES

            SECTION 5.1. OPTIONAL REDEMPTION. (a) The Securities may be
redeemed, as a whole or from time to time in part, subject to the conditions and
at the redemption prices specified in paragraph 5 of the form of Securities set
forth in Exhibits A and B hereto, which are hereby incorporated by reference and
made a part of this Indenture, together with accrued and unpaid interest to the
Redemption Date.

            (b) At any time prior to August 15, 2007, within 90 days following
the occurrence of a Change of Control, the Company may redeem the Securities, in
whole but not in part, at a redemption price equal to 100% of the principal
amount thereof plus the Applicable Premium plus accrued and unpaid 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 the relevant interest payment
date). Notice of redemption of the Securities pursuant to this SECTION 5.1(b)
shall be mailed to Holders of the Securities not more than 60 days following the
occurrence of a Change of Control, which notice shall state the redemption date
(which shall be no earlier than 30 days nor later than 60 days from the date
such notice is mailed).

            SECTION 5.2. APPLICABILITY OF ARTICLE. Redemption of Securities at
the election of the Company or otherwise, as permitted or required by any
provision of this Indenture, shall be made in accordance with such provision and
this Article.

            SECTION 5.3. ELECTION TO REDEEM; NOTICE TO TRUSTEE. The election of
the Company to redeem any Securities pursuant to SECTION 5.1 shall be evidenced

                                                                              86

not later than the earlier of the date that is 30 days prior to the Redemption
Date fixed by the Company or the date on which notice is given to the Holders
(except as provided in SECTION 5.5 or unless a shorter notice shall be
satisfactory to the Trustee), notify the Trustee of such Redemption Date and of
the principal amount of Securities to be redeemed and shall deliver to the
Trustee such documentation and records as shall enable the Trustee to select the
Securities to be redeemed pursuant to SECTION 5.4. Any such notice may be
cancelled at any time prior to notice of such redemption being mailed to any
Holder and shall thereby be void and of no effect.

            SECTION 5.4. SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED. If
less than all the Securities are to be redeemed at any time pursuant to an
optional redemption, the particular Securities to be redeemed shall be selected
not more than 60 days prior to the Redemption Date by the Trustee, from the
outstanding Securities not previously called for redemption, in compliance with
the requirements of the principal securities exchange, if any, on which such
Securities are listed, or, if such Securities are not so listed, on a PRO RATA
basis among the classes of Securities, by lot or by such other method as the
Trustee in its sole discretion shall deem fair and appropriate (and in such
manner as complies with applicable legal requirements) and which may provide for
the selection for redemption of portions of the principal of the Securities;
PROVIDED, HOWEVER, that no such partial redemption shall reduce the portion of
the principal amount of a Security not redeemed to less than $1,000.

            The Trustee shall promptly notify the Company in writing of the
Securities selected for redemption and, in the case of any Securities selected
for partial redemption, the method it has chosen for the selection of Securities
and the principal amount thereof to be redeemed.

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

            SECTION 5.5. NOTICE OF REDEMPTION. Notice of redemption shall be
given in the manner provided for in SECTION 13.2 not less than 30 nor more than
60 days prior to the Redemption Date, to each Holder of Securities to be
redeemed. At the Company's request, the Trustee shall give notice of redemption
in the Company's name and at the Company's expense; PROVIDED, HOWEVER, that the
Company shall deliver to the Trustee, at least 45 days prior to the Redemption
Date, an Officers' Certificate requesting that the Trustee give such notice at
the Company's expense and setting forth the information to be stated in such
notice as provided in the following items.

                     any,

            (3)      if less than all outstanding Securities are to be redeemed,
                     the identification of the particular Securities (or portion
                     thereof) to be redeemed, as well as

                     the aggregate principal amount of Securities to be redeemed
                     and the aggregate principal amount of Securities to be
                     outstanding after such partial redemption,

            (4)      in case any Security is to be redeemed in part only, the
                     notice which relates to such Security shall state that on
                     and after the Redemption Date, upon surrender of such
                     Security, the Holder will receive, without charge, a new
                     Security or Securities of authorized denominations for the
                     principal amount thereof remaining unredeemed,

            (5)      that on the Redemption Date the redemption price (and
                     accrued interest, if any, to the Redemption Date payable as
                     provided in SECTION 5.7) will become due and payable upon
                     each such Security, or the portion thereof, to be redeemed,
                     and, unless the Company defaults in making the redemption
                     payment, that interest on Securities called for redemption
                     (or the portion thereof) will cease to accrue on and after
                     said date,

            (6)      the place or places where such Securities are to be
                     surrendered for payment of the Redemption Price and accrued
                     interest, if any,

            (7)      the name and address of the Paying Agent,

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

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

            (10)     the paragraph of the Securities pursuant to which the
                     Securities are to be redeemed.

            SECTION 5.6. DEPOSIT OF REDEMPTION PRICE. Prior to 11:00 a.m., New
York City time, on any Redemption Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own Paying
Agent, segregate and hold in trust as provided in SECTION 2.4) an amount of
money sufficient to pay the redemption price of, and accrued interest on, all
the Securities which are to be redeemed on that date other than Securities or
portions of Securities called for redemption that have been delivered by the
Company to the Trustee for cancellation.

            SECTION 5.7. SECURITIES PAYABLE ON REDEMPTION DATE. Notice of
redemption having been given as aforesaid, the Securities or portions of
Securities so to be redeemed shall, on the Redemption Date, become due and
payable at the redemption price therein specified (together with accrued
interest, if any, to the Redemption Date), and from and after such date (unless
the Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest. Upon surrender of any
such Security for redemption in accordance with said notice, such Security shall
be paid by the Company at the redemption price, together with accrued interest,
if any, to the Redemption Date (subject to the rights of

<Page>

                                                                              88

Holders of record on the relevant record date to receive interest due on the
relevant interest payment date).

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

            SECTION 5.8. SECURITIES REDEEMED IN PART. Any Security which is to
be redeemed only in part (pursuant to the provisions of this Article) shall be
surrendered at the office or agency of the Company maintained for such purpose
pursuant to SECTION 3.14 (with, if the Company or the Trustee so requires, due
endorsement by, or a written instrument of transfer in form satisfactory to the
Company and the Trustee duly executed by, the Holder thereof or such Holder's
attorney duly authorized in writing), and the Company shall execute, and the
Trustee shall authenticate and make available for delivery to the Holder of such
Security at the expense of the Company, a new Security or Securities, of any
authorized denomination as requested by such Holder, in an aggregate principal
amount equal to and in exchange for the unredeemed portion of the principal of
the Security so surrendered, PROVIDED, that each such new Security will be in a
principal amount of $1,000 or integral multiple thereof.

                     Company or any of its Restricted Subsidiaries (or the
                     payment of which is guaranteed by the Company or any of its
                     Restricted Subsidiaries), other than Indebtedness owed to
                     the Company or a Restricted Subsidiary, whether such
                     Indebtedness or guarantee now exists, or is created after
                     the date of this Indenture, which default:

                     (a)    is caused by a failure to pay principal of, or
                            interest or premium, if any, on such Indebtedness
                            after final maturity (after giving effect to any

                     or any similar relief is granted under any foreign laws and
                     the order, decree or relief remains unstayed and in effect
                     for 60 days;

            (8)      failure by the Company or any Significant Subsidiary or
                     group of Restricted Subsidiaries that, taken together (as
                     of the latest audited consolidated financial statements for
                     Holdings, the Company and its Restricted Subsidiaries),
                     would constitute a Significant Subsidiary to pay final
                     judgments aggregating in excess of $10.0 million or its
                     foreign currency equivalent at the time (net of any amounts
                     that a reputable and creditworthy insurance company has
                     acknowledged liability or coverage for in writing), which
                     judgments are not paid, discharged or stayed for a period
                     of 60 days (the "JUDGMENT DEFAULT PROVISION"); or

            (9)      any Notes Guarantee of Holdings, a Significant Subsidiary,
                     or a group of Subsidiary Guarantors that, taken together
                     (as of the latest audited consolidated financial statements
                     for Holdings, the Company and its Restricted Subsidiaries)
                     would collectively represent a Significant Subsidiary
                     ceases to be in full force and effect (except as
                     contemplated by the terms of this Indenture) or is declared
                     null and void in a judicial proceeding or any Guarantor
                     denies or disaffirms its obligations under this Indenture
                     or its Notes Guarantee.

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

            Notwithstanding the foregoing, a Default under clauses (4) or (5) of
this SECTION 6.1 will not constitute an Event of Default until the Trustee or
the Holders of 25% or more in principal amount of the outstanding Securities
notify the Company of the Default and the Company does not cure such Default
within the time specified in clauses (4) or (5) of this SECTION 6.1 after
receipt of such notice. Such notice must specify the Default, demand that it be
remedied and state that such notice is a "Notice of Default".

            The Company shall deliver to the Trustee, within 30 days after an
Officer of the Company becomes aware of the occurrence thereof, written notice
in the form of an Officers' Certificate of any Default or Event of Default under
clauses (3), (4), (5), (6), (7), (8) or (9) of this SECTION 6.1, which such
notice shall contain the status thereof and a description of the action being
taken or proposed to be taken by the Company in respect thereof.

            SECTION 6.2. ACCELERATION. If an Event of Default (other than an
Event of Default specified in clause (7) of SECTION 6.1) occurs and is
continuing, the Trustee by notice to the Company, or the Holders of at least 25%
in principal amount of the outstanding Securities by notice to the Company and
the Trustee, may, and the Trustee at the request of such Holders shall, declare
the principal of, premium, if any, and accrued and unpaid interest, if any, on
all the Securities to be due and payable. Upon such a declaration, such
principal, premium and accrued and unpaid interest shall be due and payable
immediately. In the event of a declaration of

<Page>

                                                                              92

acceleration of the Securities because an Event of Default set forth in clause
(6) of SECTION 6.1 has occurred and is continuing, such declaration of
acceleration of the Securities shall be automatically rescinded and annulled if
the event of default or payment default triggering such Event of Default
pursuant to clause (6) of SECTION 6.1 shall be remedied or cured by the Company
and/or the relevant Restricted Subsidiary of the Company or the holders of the
relevant Indebtedness have rescinded the declaration of acceleration in respect
of such Indebtedness within 20 days after the declaration of acceleration with
respect thereto and if (a) the annulment of the acceleration of the Securities
would not conflict with any judgment or decree of a court of competent
jurisdiction and (b) all existing Events of Default, except nonpayment of
principal, premium or interest on the Securities that became due solely because
of the acceleration of the Securities, have been cured or waived. If an Event of
Default specified in clause (7) of SECTION 6.1 above occurs and is continuing,
the principal of, premium, if any, and accrued and unpaid interest on all the
Securities will become and be immediately due and payable without any
declaration or other act on the part of the Trustee or any Holders. No such
rescission shall affect any subsequent Default or Event of Default or impair any
right consequent thereto.

            SECTION 6.3. OTHER REMEDIES. If an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy to collect the payment
of principal of (or premium, if any) or interest on the Securities or to enforce
the performance of any provision of the Securities or this Indenture.

            The Trustee may maintain a proceeding even if it does not possess
any of the Securities or does not produce any of them in the proceeding. A delay
or omission by the Trustee or any Securityholder in exercising any right or
remedy accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. No remedy is
exclusive of any other remedy. All available remedies are cumulative.

            SECTION 6.4. WAIVER OF PAST DEFAULTS. The Holders of a majority in
principal amount of the outstanding Securities by notice to the Trustee may (a)
waive, by their consent (including, without limitation consents obtained in
connection with a purchase of, or tender offer or exchange offer for,
Securities), an existing Default or Event of Default and its consequences except
(i) a Default or Event of Default in the payment of the principal of, or
premium, if any, or interest on a Security or (ii) a Default or Event of Default
in respect of a provision that under SECTION 9.2 cannot be amended without the
consent of each Securityholder affected and (b) rescind any such acceleration
with respect to the Securities and its consequences if (1) rescission would not
conflict with any judgment or decree of a court of competent jurisdiction and
(2) all existing Events of Default, other than the nonpayment of the principal
of, premium, if any, and interest on the Securities that have become due solely
by such declaration of acceleration, have been cured or waived. When a Default
or Event of Default is waived, it is deemed cured, but no such waiver shall
extend to any subsequent or other Default or Event of Default or impair any
consequent right.

            SECTION 6.5. CONTROL BY MAJORITY. The Holders of a majority in
principal amount of the outstanding Securities may direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee or of
exercising any trust or power conferred on the Trustee. However, the Trustee may
refuse to follow any direction that conflicts with law

                                                                              93

or this Indenture or, subject to SECTIONS 7.1 and 7.2, that the Trustee
determines is unduly prejudicial to the rights of other Securityholders or would
involve the Trustee in personal liability; PROVIDED, HOWEVER, that the Trustee
may take any other action deemed proper by the Trustee that is not inconsistent
with such direction. Prior to taking any action hereunder, the Trustee shall be
entitled to indemnification satisfactory to it in its sole discretion against
all losses and expenses caused by taking or not taking such action.

            SECTION 6.6. LIMITATION ON SUITS. Subject to SECTION 6.7, a
Securityholder may not pursue any remedy with respect to this Indenture or the
Securities unless:

            (1)      such Holder has previously given to the Trustee written
                     notice stating that an Event of Default is continuing;

            (2)      Holders of at least 25% in principal amount of the
                     outstanding Securities have requested that the Trustee to
                     pursue the remedy;

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

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

            (5)      the Holders of a majority in principal amount of the
                     outstanding Securities have not given the Trustee a
                     direction that, in the opinion of the Trustee, is
                     inconsistent with such request within such 60-day period.

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

            SECTION 6.7. RIGHTS OF HOLDERS TO RECEIVE PAYMENT. Notwithstanding
any other provision of this Indenture (including, without limitation, SECTION
6.6), the right of any Holder to receive payment of principal of, premium (if
any) or interest on the Securities held by such Holder, on or after the
respective due dates expressed in the Securities, 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 6.8. COLLECTION SUIT BY TRUSTEE. If an Event of Default
specified in clauses (1) or (2) of SECTION 6.1 occurs and is continuing, the
Trustee may recover judgment in its own name and as trustee of an express trust
against the Company for the whole amount then due and owing (together with
interest on any unpaid interest to the extent lawful) and the amounts provided
for in SECTION 7.7.

            SECTION 6.9. TRUSTEE MAY FILE PROOFS OF CLAIM. The Trustee may file
such proofs of claim and other papers or documents as may be necessary or
advisable in order to have the claims of the Trustee and the Securityholders
allowed in any judicial proceedings relative to the Company, its Subsidiaries or
its or their respective creditors or properties and, unless prohibited by law or
applicable regulations, may vote on behalf of the Holders in any election of a
trustee in bankruptcy or other Person performing similar functions, and any
Custodian in any

                                                                              94

such judicial proceeding is hereby authorized by each Holder to make payments to
the Trustee and, in the event that the Trustee shall consent to the making of
such payments directly to the Holders, to pay to the Trustee any amount due it
for the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and its counsel, and any other amounts due the Trustee under
SECTION 7.7.

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

            FIRST: to the Trustee for amounts due under SECTION 7.7;

            SECOND: to Securityholders for amounts due and unpaid on the
     Securities for principal, premium, if any, and interest, ratably, without
     preference or priority of any kind, according to the amounts due and
     payable on the Securities for principal and interest, respectively; and

            THIRD: to the Company.

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

            SECTION 6.11. UNDERTAKING FOR COSTS. In any suit for the enforcement
of any right or remedy under this Indenture or in any suit against the Trustee
for any action taken or omitted by it as Trustee, a court in its discretion may
require the filing by any party litigant in the suit of an undertaking to pay
the costs of the suit, and the court in its discretion may assess reasonable
costs, including reasonable attorneys' fees, against any party litigant in the
suit, having due regard to the merits and good faith of the claims or defenses
made by the party litigant. This Section does not apply to a suit by the
Trustee, a suit by the Company, a suit by a Holder pursuant to SECTION 6.7 or a
suit by Holders of more than 10% in outstanding principal amount of the
Securities.

                                   ARTICLE VII

                                     TRUSTEE

            SECTION 7.1. DUTIES OF TRUSTEE. (a) If an Event of Default has
occurred and is continuing, the Trustee shall exercise the rights and powers
vested in it by this Indenture and use the same degree of care and skill in
their exercise as a prudent Person would exercise or use under the circumstances
in the conduct of such Person's own affairs; provided that if an Event of
Default occurs and is continuing, the Trustee will be under no obligation to
exercise the rights of powers under this Indenture at the request or direction
of any of the Holders unless such Holders have offered the Trustee reasonable
indemnity or security against loss, liability or expense;

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

<Page>

                                                                              95

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

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

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

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

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

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

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

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

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

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

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

                                                                              96

            (i) 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.

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

            (k) The permissive rights of the Trustee hereunder shall not be
construed as duties.

            SECTION 7.2. RIGHTS OF TRUSTEE. Subject to SECTION 7.1:

            (a) The Trustee may conclusively rely on any document (whether in
its original or facsimile form) reasonably believed by it to be genuine and to
have been signed or presented by the proper person. The Trustee need not
investigate any fact or matter stated in the document.

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

            (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 which it believes to be authorized or within its rights or
powers, unless the Trustee's conduct constitutes willful misconduct or
negligence.

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

            SECTION 7.3. INDIVIDUAL RIGHTS OF TRUSTEE. The Trustee in its
individual or any other capacity may become the owner or pledgee of Securities
and may otherwise deal with the Company or its Affiliates with the same rights
it would have if it were not Trustee. Any Paying Agent, Registrar, co-registrar
or co-paying agent may do the same with like rights. However, the Trustee must
comply with SECTIONS 7.10 and 7.11.

            SECTION 7.4. TRUSTEE'S DISCLAIMER. The Trustee shall not be
responsible for and makes no representation as to the validity or adequacy of
this Indenture or the Securities, it shall not be accountable for the Company's
use of the proceeds from the Securities, and it shall not be responsible for any
statement of the Company in this Indenture or in any document issued in
connection with the sale of the Securities or in the Securities other than the
Trustee's certificate of authentication. The Trustee shall not be responsible
for ensuring that the rate of

<Page>

                                                                              97

interest due and payable with respect to the Securities does not exceed the
highest legal rate of interest permissible under applicable federal or state
law.

            SECTION 7.5. NOTICE OF DEFAULTS. If a Default or Event of Default
occurs and is continuing and if a Trust Officer has actual knowledge thereof,
the Trustee shall mail to each Securityholder notice of the Default or Event of
Default within the earlier of 90 days after it occurs or 30 days after the
Trustee has knowledge of such default. Except in the case of a Default or Event
of Default in payment of principal of, premium (if any), or interest on any
Security (including payments pursuant to the optional redemption or required
repurchase provisions of such Security, if any), the Trustee may withhold the
notice if and so long a committee of its Trust Officers in good faith determines
that withholding the notice is in the interests of Securityholders. Nothing
herein shall be construed to require the Trustee to independently investigate
the Company's compliance with its covenants hereunder.

            SECTION 7.6. REPORTS BY TRUSTEE TO HOLDERS. As promptly as
practicable after each May 15 beginning with the May 15 following the date of
this Indenture, and in any event prior to July 15 in each year, the Trustee
shall mail to each Securityholder a brief report dated as of such May 15 that
complies with TIA Section 313(a). The Trustee also shall comply with TIA Section
313(b). The Trustee shall also transmit by mail all reports required by TIA
Section 313(c).

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

            SECTION 7.7. COMPENSATION AND INDEMNITY. The Company shall pay to
the Trustee from time to time reasonable compensation for its acceptance of this
Indenture and services hereunder as the Company and the Trustee shall from time
to time agree in writing. 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 upon request for all reasonable out-of-pocket expenses
incurred or made by it, including costs of collection, costs of preparing and
reviewing reports, certificates and other documents, costs of preparation and
mailing of notices to Securityholders and reasonable costs of counsel retained
by the Trustee in connection with the delivery of an Opinion of Counsel or
otherwise, in addition to the compensation for its services. Such expenses shall
include the reasonable compensation and expenses, disbursements and advances of
the Trustee's agents, counsel, accountants and experts. The Company shall
indemnify the Trustee against any and all loss, liability, damages, claims or
expense (including reasonable attorneys' fees and expenses) incurred by it
without negligence or willful misconduct on its part in connection with the
administration of this trust and the performance of its duties hereunder,
including the costs and expenses of enforcing this Indenture (including this
SECTION 7.7) and of defending itself against any claims (whether asserted by any
Securityholder, the Company or otherwise). 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 provide
reasonable cooperation at the Company's expense in the defense. The Trustee may
have separate counsel and the Company shall pay the fees and expenses of such
counsel provided that the Company shall not be required to pay such fees and
expenses if it assumes the

<Page>

                                                                              98

Trustee's defense, and, in the reasonable judgment of outside counsel to the
Trustee, there is no conflict of interest between the Company and the Trustee in
connection with such defense. The Company shall not be under any obligation to
pay for any written settlement without its consent, which consent shall not be
unreasonably delayed, conditioned or withheld. The Company need not reimburse
any expense or indemnify against any loss, liability or expense incurred by the
Trustee through the Trustee's own willful misconduct or negligence.

            To secure the Company's payment obligations in this Section, the
Trustee shall have a lien prior to the Securities on all money or property held
or collected by the Trustee other than money or property held in trust to pay
principal of and interest on particular Securities. The Trustee's right to
receive payment of any amounts due under this SECTION 7.7 shall not be
subordinate to any other liability or Indebtedness of the Company.

            The Company's payment obligations pursuant to this Section shall
survive the discharge of this Indenture or the Trustee's resignation or removal
hereunder. When the Trustee incurs expenses after the occurrence of a Default
specified in clause (7) of SECTION 6.1 with respect to the Company, the expenses
are intended to constitute expenses of administration under any Bankruptcy Law.

            SECTION 7.8. REPLACEMENT OF TRUSTEE. The Trustee may resign at any
time by so notifying the Company. The Holders of a majority in principal amount
of the Securities may remove the Trustee by so notifying the Trustee and may
appoint a successor Trustee. The Company shall remove the Trustee if:

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

            (2) the Trustee is adjudged bankrupt or insolvent;

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

            (4) the Trustee otherwise becomes incapable of acting.

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

            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 Securityholders. The retiring Trustee shall promptly transfer all
property held by it as Trustee to the successor Trustee, subject to the lien
provided for in SECTION 7.7.

            If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee or the Holders of
at least 10% in principal amount of

<Page>

                                                                              99

the Securities may petition, at the Company's expense, any court of competent
jurisdiction for the appointment of a successor Trustee.

            If the Trustee fails to comply with SECTION 7.10, unless the
Trustee's duty to resign is stayed as provided in Section 310(b) of the TIA, any
Securityholder who has been a bona fide Holder of a Security for at least six
months may petition any court of competent jurisdiction for the removal of the
Trustee and the appointment of a successor Trustee.

            Notwithstanding the replacement of the Trustee pursuant to this
Section, the Company's obligations under SECTION 7.7 shall continue for the
benefit of the retiring Trustee.

            SECTION 7.9. SUCCESSOR TRUSTEE BY MERGER. If the Trustee
consolidates with, merges or converts into, or transfers all or substantially
all its corporate trust business or assets to, another corporation or banking
association, the resulting, surviving or transferee corporation without any
further act shall be the successor Trustee.

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

            SECTION 7.10. ELIGIBILITY; DISQUALIFICATION. The Trustee shall at
all times satisfy the requirements of TIA Section 310(a). The Trustee shall have
a combined capital and surplus of at least $100 million as set forth in its most
recent published annual report of condition. The Trustee shall comply with TIA
Section 310(b); PROVIDED, HOWEVER, that there shall be excluded from the
operation of TIA Section 310(b)(1) any indenture or indentures under which other
securities or certificates of interest or participation in other securities of
the Company are outstanding if the requirements for such exclusion set forth in
TIA Section 310(b)(1) are met.

            SECTION 7.11. PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY. The
Trustee shall comply with TIA Section 311(a), excluding any creditor
relationship listed in TIA Section 311(b). A Trustee who has resigned or been
removed shall be subject to TIA Section 311(a) to the extent indicated.

            SECTION 7.12. TRUSTEE'S APPLICATION FOR INSTRUCTION FROM THE
COMPANY. Any application by the Trustee for written instructions from the
Company may, at the option of the Trustee, set forth in writing any action
proposed to be taken or omitted by the Trustee under this Indenture and the date
on and/or after which such action shall be taken or such omission shall be
effective. The Trustee shall not be liable for any action taken by, or omission
of, the Trustee in accordance with a proposal included in such application on or
after the date specified in such application (which date shall not be less than
three Business Days after the date any officer of the Company actually receives
such application, unless any such officer shall have consented in

<Page>

                                                                             100

writing to any earlier date) unless prior to taking any such action (or the
effective date in the case of an omission), the Trustee shall have received
written instructions in response to such application specifying the action to be
taken or omitted.

                                  ARTICLE VIII

                       DISCHARGE OF INDENTURE; DEFEASANCE

            SECTION 8.1. DISCHARGE OF LIABILITY ON SECURITIES; DEFEASANCE. (a)
Subject to SECTION 8.1(c), when (i)(x) the Company delivers to the Trustee all
outstanding Securities (other than Securities replaced pursuant to SECTION 2.10)
for cancellation or (y) all outstanding Securities not theretofore delivered for
cancellation have become due and payable, whether at maturity or upon redemption
or will become due and payable within one year or are to be called for
redemption within one year under arrangements satisfactory to the Trustee for
the giving of notice of redemption pursuant to ARTICLE V hereof and the Company
or any Guarantor irrevocably deposits or causes to be deposited with the Trustee
as trust funds in trust solely for the benefit of the Holders money 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 such Securities not
theretofore delivered to the Trustee for cancellation for principal, premium, if
any, 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 under this Indenture and the Securities;
and (iv) the Company has delivered irrevocable instructions to the Trustee under
this Indenture to apply the deposited money toward the payment of such
Securities at maturity or the Redemption Date, as the case may be, then the
Trustee shall acknowledge satisfaction and discharge of this Indenture on demand
of the Company (accompanied by an Officers' Certificate and an Opinion of
Counsel stating that all conditions precedent specified herein relating to the
satisfaction and discharge of this Indenture have been complied with) and at the
cost and expense of the Company.

            (b) Subject to SECTIONS 8.1(c) and 8.2, the Company at any time may
terminate (i) all its obligations under the Securities and this Indenture
("LEGAL DEFEASANCE OPTION"), and after giving effect to such legal defeasance,
any omission to comply with such obligations shall no longer constitute a
Default or Event of Default or (ii) its obligations under SECTIONS 3.2, 3.3,
3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 3.10, 3.11, 3.12, 3.13, 3.17 and 4.1(3) and 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 with such covenants shall
no longer constitute a Default or an Event of Default under SECTIONS 6.1(3),
6.1(4) and 6.1(5) and the operation of SECTIONS 6.1(6), 6.1(7) (but only with
respect to a Significant Subsidiary or group of Restricted Subsidiaries that
would constitute a Significant Subsidiary), 6.1(8) and 6.1(9), and the events
specified in such Sections shall no longer constitute an Event of Default

<Page>

                                                                             101

(clause (ii) being referred to as the "COVENANT DEFEASANCE OPTION"), but except
as specified above, the remainder of this Indenture and the Securities shall be
unaffected thereby. The Company may exercise its legal defeasance option
notwithstanding its prior exercise of its covenant defeasance option. If the
Company exercises its covenant defeasance option, the Company may elect to have
any Notes Guarantees in effect at such time terminate.

            If the Company exercises its legal defeasance option, payment of the
Securities may not be accelerated because of an Event of Default, and the Notes
Guarantees in effect at such time shall terminate. If the Company exercises its
covenant defeasance option, payment of the Securities may not be accelerated
because of an Event of Default specified in SECTIONS 6.1(3), 6.1(4) (as such
Section relates to SECTIONS 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 3.10, 3.11,
3.12, 3.13 and 3.17), 6.1(5), 6.1(6), 6.1(7) (but only with respect to a
Significant Subsidiary or group of Restricted Subsidiaries that would constitute
a Significant Subsidiary), 6.1(8) or 6.1(9) or because of the failure of the
Company to comply with SECTION 4.1(3).

            Upon satisfaction of the conditions set forth herein and upon
request of the Company, the Trustee shall acknowledge in writing the discharge
of those obligations that the Company terminates.

            (c) Notwithstanding the provisions of SECTIONS 8.1(a) and (b), the
Company's obligations in SECTIONS 2.2, 2.3, 2.4, 2.5, 2.6, 2.10, 2.11, 2.12,
3.1, 3.14, 3.15, 3.16, 3.18, 3.19, 3.20, 6.7, 7.7, 7.8 and in this ARTICLE VIII
shall survive until the Securities have been paid in full. Thereafter, the
Company's obligations in SECTIONS 7.7, 8.4 and 8.5 shall survive.

            SECTION 8.2. CONDITIONS TO DEFEASANCE. The Company may exercise its
legal defeasance option or its covenant defeasance option only if:

            (1) the Company irrevocably deposits in trust with the Trustee for
     the benefit of the Holders money in U.S. dollars or U.S. Government
     Obligations or a combination thereof, the principal of and interest
     (without reinvestment) on which will be sufficient, or a combination
     thereof sufficient, for the payment of principal, premium, if any, and
     interest on the Securities to maturity or redemption, as the case may be;

            (2) the Company delivers to the Trustee a certificate from a
     nationally recognized firm of independent accountants expressing their
     opinion that the payments of principal and interest when due and without
     reinvestment on the deposited U.S. Government Obligations plus any
     deposited money without investment will provide cash at such times and in
     such amounts as will be sufficient to pay principal and interest when due
     on all the Securities to maturity or redemption, as the case may be;

            (3) no Default or Event of Default shall have occurred and be
     continuing on the date of such deposit or, with respect to certain
     bankruptcy or insolvency Events of Default, on the 91st day after such date
     of deposit;

            (4) such legal defeasance or covenant defeasance shall not result in
     a breach or violation of, or constitute a Default under, this Indenture or
     any other material agreement or instrument to which the Company or any of
     its Subsidiaries is a party or by which the Company or any of its
     Subsidiaries is bound;

            (5) the Company shall have delivered to the Trustee an Opinion of
     Counsel (subject to customary assumptions and exclusions) to the effect
     that (A) the Securities and (B) assuming no intervening bankruptcy of the
     Company between the date of deposit and the 91st day following the deposit
     and that no Holder of the Securities is an insider of the Company, after
     the 91st day following the deposit, the trust funds will not be subject to
     the effect of any applicable bankruptcy, insolvency, reorganization or
     similar laws affecting creditors' right generally;

            (6) the deposit does not constitute a default under any other
     agreement binding on the Company;

            (7) the Company delivers to the Trustee an Opinion of Counsel
     (subject to customary assumptions and exclusions) to the effect that the
     trust resulting from the deposit does not constitute, or is qualified as, a
     regulated investment company under the Investment Company Act of 1940;

            (8) in the case of the legal defeasance option, the Company shall
     have delivered to the Trustee an Opinion of Counsel (subject to customary
     assumptions and exclusions) in the United States stating that (i) the
     Company has received from, or there has been published by, the Internal
     Revenue Service a ruling, or (ii) since the date of this Indenture there
     has been a change in the applicable federal income tax law, in either case
     to the effect that, and based thereon such Opinion of Counsel shall confirm
     that, the Securityholders will not recognize income, gain or loss for
     federal income tax purposes as a result of such defeasance and will be
     subject to federal income tax on the same amounts, in the same manner and
     at the same times as would have been the case if such legal defeasance had
     not occurred;

            (9) in the case of the covenant defeasance option, the Company shall
     have delivered to the Trustee an Opinion of Counsel (subject to customary
     assumptions and exclusions) in the United States to the effect that the
     Securityholders will not recognize income, gain or loss for federal income
     tax purposes as a result of such deposit and covenant defeasance and will
     be subject to federal income tax on the same amount, in the same manner and
     at the same times as would have been the case if such deposit and covenant
     defeasance had not occurred; and

            (10) the Company delivers to the Trustee an Officers' Certificate
     and an Opinion of Counsel, each stating that all conditions precedent to
     the defeasance and discharge of the Securities and this Indenture as
     contemplated by this ARTICLE VIII have been complied with.

            SECTION 8.3. APPLICATION OF TRUST MONEY. The Trustee shall hold in
trust money or U.S. Government Obligations deposited with it pursuant to this
ARTICLE VIII. It shall apply the deposited money and the money from U.S.
Government Obligations through the Paying Agent and in accordance with this
Indenture to the payment of principal of and interest on the Securities.

                                                                             103

            SECTION 8.4. REPAYMENT TO COMPANY. The Trustee and the Paying Agent
shall promptly turn over to the Company upon request any excess money, U.S.
Government Obligations or securities held by them upon payment of all the
obligations under this Indenture.

            Subject to any applicable abandoned property law, the Trustee and
the Paying Agent shall pay to the Company upon request any money held by them
for the payment of principal of or interest on the Securities that remains
unclaimed for two years, and, thereafter, Securityholders entitled to the money
must look to the Company for payment as general creditors.

            SECTION 8.5. INDEMNITY FOR U.S. GOVERNMENT OBLIGATIONS. The Company
shall pay and shall indemnify the Trustee against any tax, fee or other charge
imposed on or assessed against deposited U.S. Government Obligations or the
principal and interest received on such U.S. Government Obligations.

            SECTION 8.6. REINSTATEMENT. If the Trustee or Paying Agent is unable
to apply any money or U.S. Government Obligations in accordance with this
ARTICLE VIII by reason of any legal proceeding or by reason of any order or
judgment of any court or governmental authority enjoining, restraining or
otherwise prohibiting such application, the obligations of the Company under
this Indenture and the Securities shall be revived and reinstated as though no
deposit had occurred pursuant to this ARTICLE VIII until such time as the
Trustee or Paying Agent is permitted to apply all such money or U.S. Government
Obligations in accordance with this ARTICLE VIII; PROVIDED, HOWEVER, that, if
the Company has made any payment of interest on or principal of any Securities
because of the reinstatement of its obligations, the Company shall be subrogated
to the rights of the Holders of such Securities to receive such payment from the
money or U.S. Government Obligations held by the Trustee or Paying Agent.

                                   ARTICLE IX

                                   AMENDMENTS

            SECTION 9.1. WITHOUT CONSENT OF HOLDERS. The Company, the Guarantors
and the Trustee may amend this Indenture or the Securities without notice to or
consent of any Securityholder:

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

            (2) to comply with ARTICLE IV in respect of the assumption by a
     Successor Company of an obligation of the Company under this Indenture;

            (3) to provide for uncertificated Securities in addition to or in
     place of certificated Securities; PROVIDED, HOWEVER, that the
     uncertificated Securities are issued in registered form for purposes of
     Section 163(f) of the Code or in a manner such that the uncertificated
     Securities are described in Section 163(f)(2)(B) of the Code;

            (4) to add Guarantees with respect to the Securities or to release a
     Subsidiary Guarantor in accordance with this Indenture;

<Page>

                                                                             104

            (5) to secure the Securities;

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

            (7) to make any change that does not adversely affect the rights of
     any Securityholder;

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

            (9) to provide for the issuance of the Exchange Securities, which
     will have terms substantially identical in all respects to the Initial
     Securities or the Additional Securities, as the case may be (except that
     the transfer restrictions contained in the Initial Securities or the
     Additional Securities, if any, will be modified or eliminated, as
     appropriate), and which will be treated, together with any outstanding
     Initial Securities or Additional Securities, as a single class of
     securities; or

            (10) make any change in the subordination provisions of this
     Indenture that would limit or terminate the benefits available to any
     holder of Senior Indebtedness of the Company or a holder of Guarantor
     Senior Indebtedness (or any Representative thereof) under such
     subordination provisions.

However, no amendment may be made to the provisions of ARTICLE X or XII that
adversely affect the rights of any holder of Senior Indebtedness then
outstanding unless the holders of such Senior Indebtedness (or any group or
Representative thereof authorized to give a consent) consent to such change.

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

            SECTION 9.2. WITH CONSENT OF HOLDERS. The Company, the Guarantors
and the Trustee may amend this Indenture or the Securities without notice to any
Securityholder but with the written consent of the Holders of at least a
majority in principal amount of the Securities then outstanding (including,
without limitation, consents obtained in connection with a purchase of, or
tender offer or exchange offer for, Securities) and compliance with the
provisions of this Indenture may be waived with the written consent of the
Holders of at least a majority in principal amount of the Securities then
outstanding (including, without limitation, consents obtained in connection with
a purchase of, or tender offer or exchange offer for, Securities). However,
without the consent of each Securityholder affected, an amendment or waiver may
not:

            (1) reduce the amount of Securities whose Holders must consent to an
     amendment;

            (2) reduce the stated rate of or extend the stated time for payment
     of interest or additional interest on any Security;

<Page>

                                                                             105

            (3) reduce the principal of or extend the Stated Maturity of any
     Security;

            (4) reduce the premium payable upon the redemption or repurchase of
     any Security or change the time at which any Security may or shall be
     redeemed or repurchased as described under ARTICLE V, whether through an
     amendment or waiver of provisions in the covenants, definitions or
     otherwise;

            (5) make any Security payable in money other than that stated in the
     Security;

            (6) impair the right of any Holder to receive payment of, premium,
     if any, principal of and interest on such Holder's Securities on or after
     the due dates therefor or to institute suit for the enforcement of any
     payment on or with respect to such Holder's Securities;

            (7) make any change to the amendment provisions which require each
     Holder's consent or in the waiver provisions;

            (8) make any change to ARTICLE X or XII that adversely affects the
     rights of any Holder of Securities; or

            (9) modify the Notes Guarantees in any manner adverse to the holders
     of the Securities.

            It shall not be necessary for the consent of the Holders under this
Section to approve the particular form of any proposed amendment or waiver, but
it shall be sufficient if such consent approves the substance thereof. A consent
to any amendment or waiver under this Indenture by any Holder of the Securities
given in connection with a tender of such Holder's Securities will not be
rendered invalid by such tender.

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

            SECTION 9.3. COMPLIANCE WITH TRUST INDENTURE ACT. Every amendment to
this Indenture or the Securities shall comply with the TIA as then in effect.

            SECTION 9.4. REVOCATION AND EFFECT OF CONSENTS AND WAIVERS. A
consent to an amendment or a waiver by a Holder of a Security shall bind the
Holder and every subsequent Holder of that Security or portion of the Security
that evidences the same debt as the consenting Holder's Security, even if
notation of the consent or waiver is not made on the Security. However, any such
Holder or subsequent Holder may revoke the consent or waiver as to such Holder's
Security or portion of the Security if the Trustee receives the notice of
revocation before the date the amendment or waiver becomes effective. After an
amendment or waiver becomes effective, it shall bind every Securityholder. An
amendment or waiver shall become effective upon receipt by the Trustee of the
requisite number of written consents under Section 9.1 or 9.2 as applicable.

                                                                             106

            The Company may, but shall not be obligated to, fix a record date
for the purpose of determining the Securityholders entitled to give their
consent or take any other action described above or required or permitted to be
taken pursuant to this Indenture. If a record date is fixed, then
notwithstanding the immediately preceding paragraph, those Persons who were
Securityholders at such record date (or their duly designated proxies), and only
those Persons, shall be entitled to give such consent or to revoke any consent
previously given or to take any such action, whether or not such Persons
continue to be Holders after such record date. No such consent shall become
valid or effective more than 120 days after such record date.

            SECTION 9.5. NOTATION ON OR EXCHANGE OF SECURITIES. If an amendment
changes the terms of a Security, the Trustee may require the Holder of the
Security to deliver it to the Trustee. The Trustee may place an appropriate
notation on the Security regarding the changed terms and return it to the
Holder. Alternatively, if the Company or the Trustee so determines, the Company
in exchange for the Security shall issue and the Trustee shall authenticate a
new Security that reflects the changed terms. Failure to make the appropriate
notation or to issue a new Security shall not affect the validity of such
amendment.

            SECTION 9.6. TRUSTEE TO SIGN AMENDMENTS. The Trustee shall sign any
amendment authorized pursuant to this ARTICLE IX if the amendment does not
adversely affect the rights, duties, liabilities or immunities of the Trustee.
If it does, the Trustee may but need not sign it. In signing such amendment the
Trustee shall be entitled to receive indemnity reasonably satisfactory to it and
to receive, and (subject to SECTIONS 7.1 AND 7.2) shall be fully protected in
relying upon an Officers' Certificate and an Opinion of Counsel stating that
such amendment is authorized or permitted by this Indenture.

                                    ARTICLE X

                                  SUBORDINATION

            SECTION 10.1. AGREEMENT TO SUBORDINATE. The Company agrees, and each
Securityholder by accepting a Security agrees, that the Indebtedness evidenced
by, and all other obligations in respect of, the Securities is subordinated in
right of payment, to the extent and in the manner provided in this ARTICLE X, to
the prior payment of all Senior Indebtedness and that the subordination is for
the benefit of and enforceable by the holders of Senior Indebtedness. The
Securities shall in all respects rank PARI PASSU with all other Senior
Subordinated Indebtedness of the Company and only Indebtedness of the Company
that is Senior Indebtedness will rank senior to the Securities in accordance
with the provisions set forth herein. All provisions of this ARTICLE X shall be
subject to SECTION 10.12.

            SECTION 10.2. LIQUIDATION, DISSOLUTION, BANKRUPTCY. Upon any payment
or distribution of the assets of the Company to creditors upon a total or
partial liquidation or a total or partial dissolution of the Company or in a
reorganization, bankruptcy, insolvency, receivership or similar proceeding
relating to the Company or its properties or an assignment for the benefit of
creditors or marshalling of the Company's assets or liabilities:

<Page>

                                                                             107

            (1)      holders of Senior Indebtedness shall be entitled to receive
     payment in full in cash or Cash Equivalents of all Senior Indebtedness
     (including interest accruing after, or which would accrue but for, the
     commencement of any proceeding at the rate specified in the applicable
     Senior Indebtedness, whether or not a claim for such interest would be
     allowed) before Securityholders shall be entitled to receive any payment of
     principal of or interest on or other amounts with respect to the Securities
     from the Company; and

            (2)      until the Senior Indebtedness is paid in full in cash or
     Cash Equivalents, any payment or distribution to which Securityholders
     would be entitled but for this ARTICLE X shall be made to holders of Senior
     Indebtedness, as their respective interests may appear, except that the
     holders of the Securities may receive Capital Stock (other than
     Disqualified Stock) issued by the Company to pay interest on the Securities
     or issued in exchange for the Securities, (ii) securities substantially
     identical to the Securities issued by the Company in payment of interest
     thereon or (iii) securities issued by the Company which are subordinated to
     Senior Indebtedness at least to the same extent as the Securities and
     having an Average Life at least equal to the remaining Average Life of the
     Securities.

            SECTION 10.3. DEFAULT ON SENIOR INDEBTEDNESS. The Company shall not
pay the principal of, premium (if any) or interest on or other payment
obligations in respect of the Securities or make any deposit pursuant to SECTION
8.2 or repurchase, redeem or otherwise retire any Securities (collectively, "pay
the Securities") if (i) any Senior Indebtedness is not paid when due in cash or
Cash Equivalents or (ii) any other default on Senior Indebtedness occurs and the
maturity of such Senior Indebtedness is accelerated in accordance with its terms
unless, in either case, (x) the default has been cured or waived and any such
acceleration has been rescinded or (y) such Senior Indebtedness has been paid in
full in cash or Cash Equivalents; PROVIDED, HOWEVER, that the Company may pay
the Securities, without regard to the foregoing, if the Company and the Trustee
receive written notice approving such payment from the Representative of the
Senior Indebtedness with respect to which either of the events set forth in
clause (i) or (ii) of this sentence has occurred and is continuing. During the
continuance of any default (other than a default described in clause (i) of the
preceding sentence or a default resulting in acceleration described in clause
(ii) of the preceding sentence) with respect to any Designated Senior
Indebtedness pursuant to which the maturity thereof may be accelerated
immediately without further notice (except such notice as may be required to
effect such acceleration) or the expiration of any applicable grace periods, the
Company may not pay the Securities for a period (a "PAYMENT BLOCKAGE PERIOD")
commencing upon the receipt by the Trustee (with a copy to the Company) of
written notice (a "BLOCKAGE NOTICE") of such default from the Representative(s)
of the holders of such Designated Senior Indebtedness specifying an election to
effect a Payment Blockage Period and ending 179 days thereafter (or earlier if
such Payment Blockage Period is terminated (i) by written notice to the Trustee
and the Company from the Person or Persons who gave such Blockage Notice, (ii)
because the default giving rise to such Blockage Notice is no longer continuing
or (iii) because such Designated Senior Indebtedness has been repaid in full).
Notwithstanding the provisions of the immediately preceding sentence, unless the
holders of such Designated Senior Indebtedness or the Representative(s) of such
holders shall have accelerated the maturity of such Designated Senior
Indebtedness, the Company may resume payments on the Securities after the end of
such Payment Blockage Period (including any missed payments). Not more than one
Blockage

<Page>

                                                                             108

Notice may be given, and not more than one Payment Blockage may occur, in any
consecutive 360-day period, irrespective of the number of defaults with respect
to Designated Senior Indebtedness during such period. However, if any Blockage
Notice within such 360-day period is given by or on behalf of any holders of
Designated Senior Indebtedness other than the Bank Indebtedness, the
Representative of the Bank Indebtedness may give another Blockage Notice within
such period. In no event, however, may the total number of days during which any
Payment Blockage Period or Periods is in effect exceed 179 days in the aggregate
during any 360 consecutive day period. For purposes of this paragraph, no
default or event of default that existed or was continuing on the date of the
commencement of any Payment Blockage Period with respect to the Designated
Senior Indebtedness initiating such Payment Blockage Period shall be, or be
made, the basis of the commencement of a subsequent Payment Blockage Period by
the Representative of such Designated Senior Indebtedness, whether or not within
a period of 360 consecutive days, unless such default or event of default shall
have been cured or waived for a period of not less than 90 consecutive days.

            SECTION 10.4. ACCELERATION OF PAYMENT OF SECURITIES. If payment of
the Securities is accelerated because of an Event of Default, the Company or the
Trustee shall promptly notify the holders of the Designated Senior Indebtedness
(or their Representatives) of the acceleration; PROVIDED, HOWEVER, that the
Company and the Trustee shall be obligated to notify such a Representative only
if such Representative has delivered or caused to be delivered to the Company or
the Trustee an address for service of such a notice (and the Company and the
Trustee shall only be obligated to deliver the notice to the address so
specified). If any Designated Senior Indebtedness is outstanding, the Company
shall not pay the Securities until five Business Days after the holders or
Representative(s) of such Designated Senior Indebtedness receives notice of such
acceleration and, thereafter, may pay the Securities, only if this ARTICLE X
otherwise permits payments at that time.

            SECTION 10.5. WHEN DISTRIBUTION MUST BE PAID OVER. If a distribution
is made to Securityholders that because of this ARTICLE X should not have been
made to them, the Securityholders who receive the distribution shall hold it in
trust for holders of Senior Indebtedness and promptly pay it over to them as
their respective interests may appear.

            SECTION 10.6. SUBROGATION. After all Senior Indebtedness is paid in
full and until the Securities are paid in full, Securityholders shall be
subrogated to the rights of holders of Senior Indebtedness to receive
distributions applicable to Senior Indebtedness. A distribution made under this
ARTICLE X to holders of Senior Indebtedness which otherwise would have been made
to Securityholders is not, as between the Company and Securityholders, a payment
by the Company of Senior Indebtedness.

            SECTION 10.7. RELATIVE RIGHTS. This ARTICLE X defines the relative
rights of Securityholders and holders of Senior Indebtedness. Nothing in this
Indenture shall:

            (1)      impair, as between the Company and Securityholders, the
     obligation of the Company which is absolute and unconditional, to pay
     principal of and interest on the Securities in accordance with their terms;
     or

<Page>

                                                                             109

            (2)      prevent the Trustee or any Securityholder from exercising
     its available remedies upon a Default or Event of Default, subject to the
     rights of holders of Senior Indebtedness to receive distributions otherwise
     payable to Securityholders.

            SECTION 10.8. SUBORDINATION MAY NOT BE IMPAIRED BY COMPANY. No right
of any holder of Senior Indebtedness to enforce the subordination of the
Indebtedness evidenced by the Securities shall be impaired by any act or failure
to act by the Company or by the failure of any of them to comply with this
Indenture.

            SECTION 10.9. RIGHTS OF TRUSTEE AND PAYING AGENT. Notwithstanding
SECTION 10.3, the Trustee or Paying Agent may continue to make payments on the
Securities and shall not be charged with knowledge of the existence of facts
that would prohibit the making of any such payments unless, not less than two
Business Days prior to the date of such payment, a Trust Officer of the Trustee
receives notice in writing satisfactory to it that payments may not be made
under this ARTICLE X. The Company, the Registrar, the Paying Agent, a
Representative or a holder of Senior Indebtedness may give the notice; PROVIDED,
HOWEVER, that, if an issue of Senior Indebtedness has a Representative, only the
Representative may give the notice.

            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. The
Registrar and the Paying Agent may do the same with like rights. The Trustee
shall be entitled to all the rights set forth in this ARTICLE X with respect to
any Senior Indebtedness which may at any time be held by it, to the same extent
as any other holder of Senior Indebtedness; and nothing in ARTICLE VII shall
deprive the Trustee of any of its rights as such holder. Nothing in this ARTICLE
X shall apply to claims of, or payments to, the Trustee under or pursuant to
SECTION 7.7.

            SECTION 10.10. DISTRIBUTION OR NOTICE TO REPRESENTATIVE. 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 (if
any).

            SECTION 10.11. ARTICLE X NOT TO PREVENT EVENTS OF DEFAULT OR LIMIT
RIGHT TO ACCELERATE. The failure to make a payment in respect of the Securities,
by reason of any provision in this ARTICLE X, shall not be construed as
preventing the occurrence of a Default or Event of Default. Nothing in this
ARTICLE X shall have any effect on the right of the Securityholders or the
Trustee to accelerate the maturity of the Securities.

            SECTION 10.12. TRUST MONEYS NOT SUBORDINATED. Notwithstanding
anything contained herein to the contrary, payments from money or the proceeds
of U.S. Government Obligations held in trust under ARTICLE VIII by the Trustee
for the payment of principal of premium, if any, and interest on the Securities
shall not be subordinated to the prior payment of any Senior Indebtedness or
subject to the restrictions set forth in this ARTICLE X, and none of the
Securityholders shall be obligated to pay over any such amount to the Company,
any holder of Senior Indebtedness, or any other creditor of the Company.

            SECTION 10.13. TRUSTEE ENTITLED TO RELY. Upon any payment or
distribution pursuant to this ARTICLE X, the Trustee and the Securityholders
shall be entitled to rely (i) upon any order or decree of a court of competent
jurisdiction in which any proceedings of the nature

referred to in SECTION 10.2 are pending, (ii) upon a certificate of the
liquidating trustee or agent or other Person making such payment or distribution
to the Trustee or to the Securityholders or (iii) upon the Representatives for
the holders of Senior Indebtedness for the purpose of ascertaining the Persons
entitled to participate in such payment or distribution, the holders of Senior
Indebtedness and other Indebtedness of the Company, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts pertinent thereto or to this ARTICLE X. In the event that the Trustee
determines, in good faith, that evidence is required with respect to the right
of any Person as a holder of Senior Indebtedness to participate in any payment
or distribution pursuant to this ARTICLE X, the Trustee may request such Person
to furnish evidence to the reasonable satisfaction of the Trustee as to the
amount of Senior Indebtedness held by such Person, the extent to which such
Person is entitled to participate in such payment or distribution and other
facts pertinent to the rights of such Person under this ARTICLE X, and, if such
evidence is not furnished, the Trustee may defer any payment to such Person
pending judicial determination as to the right of such Person to receive such
payment. The provisions of SECTIONS 7.1 AND 7.2 shall be applicable to all
actions or omissions of actions by the Trustee pursuant to this ARTICLE X.

            SECTION 10.14. TRUSTEE TO EFFECTUATE SUBORDINATION. Each
Securityholder by accepting a Security authorizes and directs the Trustee on its
behalf to take such action as may be necessary or appropriate to acknowledge or
effectuate the subordination between the Securityholders and the holders of
Senior Indebtedness as provided in this ARTICLE X and appoints the Trustee as
attorney-in-fact for any and all such purposes.

            SECTION 10.15. 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 mistakenly pay over or distribute to Securityholders 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 X or otherwise.

            SECTION 10.16. RELIANCE BY HOLDERS OF SENIOR INDEBTEDNESS ON
INDEBTEDNESS ON SUBORDINATION PROVISIONS. Each Securityholder by accepting a
Security acknowledges and agrees that the foregoing subordination provisions
are, and are intended to be, an inducement and a consideration to each holder of
any Senior Indebtedness, whether such Senior Indebtedness was created or
acquired before or after the issuance of the Securities, to acquire, or to
continue to hold, such Senior Indebtedness and such holder of Senior
Indebtedness shall be deemed conclusively to have relied on such subordination
provisions in acquiring and continuing to hold, or in continuing to hold, such
Senior Indebtedness.

                                   ARTICLE XI

                                 NOTES GUARANTEE

            SECTION 11.1. NOTES GUARANTEE. Each Guarantor hereby fully,
unconditionally and irrevocably guarantees, as primary obligor and not merely as
surety, jointly and severally with each other Guarantor, to each Holder of the
Securities and the Trustee the full and punctual payment when due, whether at
maturity, by acceleration, by redemption or otherwise, of the

<Page>

                                                                             111

principal of, premium, if any, and interest on the Securities and all other
monetary obligations of the Company under this Indenture (all the foregoing
being hereinafter collectively called the "OBLIGATIONS"). Each Guarantor further
agrees (to the extent permitted by law) that the Obligations may be extended or
renewed, in whole or in part, without notice or further assent from it, and that
it will remain bound under this ARTICLE XI notwithstanding any extension or
renewal of any Obligation.

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

            Each Guarantor further agrees that its Notes Guarantee herein
constitutes a Guarantee of payment when due (and not a Guarantee of collection)
and waives any right to require that any resort be had by any Holder to any
security held for payment of the Obligations.

            Except as expressly set forth in SECTIONS 8.1(b) and 11.2, the
obligations of each Guarantor hereunder shall not be subject to any reduction,
limitation, impairment or termination for any reason (other than payment of the
Obligations in full), including any claim of waiver, release, surrender,
alteration or compromise, and shall not be subject to any defense of setoff,
counterclaim, recoupment or termination whatsoever or by reason of the
invalidity, illegality or unenforceability of the Obligations or otherwise.
Without limiting the generality of the foregoing, the obligations of each
Guarantor herein shall not be discharged or impaired or otherwise affected by
the failure of any Holder to assert any claim or demand or to enforce any remedy
under this Indenture, the Securities or any other agreement, by any waiver or
modification of any thereof, by any default, failure or delay, willful or
otherwise, in the performance of the Obligations, or by any other act or thing
or omission or delay to do any other act or thing which may or might in any
manner or to any extent vary the risk of any Guarantor or would otherwise
operate as a discharge of such Guarantor as a matter of law or equity.

            Each Guarantor agrees that its Notes Guarantee herein shall remain
in full force and effect until payment in full of all the Obligations or such
Notes Guarantee is released upon the merger or the sale of all the Capital Stock
or assets of the Guarantor in compliance with SECTION 3.7 and ARTICLE IV. Each
Guarantor further agrees that its Notes Guarantee herein shall continue to be
effective or be reinstated, as the case may be, if at any time payment, or any
part thereof, of principal of or interest on any of the Obligations is rescinded
or must otherwise be restored by any Holder upon the bankruptcy or
reorganization of the Company or otherwise.

            In furtherance of the foregoing and not in limitation of any other
right which any Holder has at law or in equity against any Guarantor by virtue
hereof, upon the failure of the

                                                                             112

Company to pay any of the Obligations when and as the same shall become due,
whether at maturity, by acceleration, by redemption or otherwise, each Guarantor
hereby promises to and will, upon receipt of written demand by the Trustee,
forthwith pay, or cause to be paid, in cash, to the Holders an amount equal to
the sum of (i) the unpaid amount of such Obligations then due and owing and (ii)
accrued and unpaid interest on such Obligations then due and owing (but only to
the extent not prohibited by law).

            Each Guarantor further agrees that, as between such Guarantor, on
the one hand, and the Holders, on the other hand, (x) the maturity of the
Obligations guaranteed hereby may be accelerated as provided in this Indenture
for the purposes of its Notes Guarantee herein, notwithstanding any stay,
injunction or other prohibition preventing such acceleration in respect of the
Obligations guaranteed hereby and (y) in the event of any such declaration of
acceleration of such Obligations, such Obligations (whether or not due and
payable) shall forthwith become due and payable by the Guarantor for the
purposes of this Notes Guarantee.

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

            SECTION 11.2. LIMITATION ON LIABILITY; TERMINATION, RELEASE AND
DISCHARGE.

            (a)      The obligations of each Guarantor hereunder will be limited
to the maximum amount as will, after giving effect to all other contingent and
fixed liabilities of such Guarantor (including, without limitation, any
guarantees under the Senior Credit Agreement) and after giving effect to any
collections from or payments made by or on behalf of any other Guarantor in
respect of the obligations of such other Guarantor under its Notes Guarantee or
pursuant to its contribution obligations under this Indenture, result in the
obligations of such Guarantor under its Notes Guarantee not constituting a
fraudulent conveyance or fraudulent transfer under federal or state law and not
otherwise being void or voidable under any similar laws affecting the rights of
creditors generally.

            (b)      Subject to ARTICLE III and ARTICLE IV, each Guarantor may
consolidate with or merge into or sell its assets to the Company or another
Guarantor without limitation. Upon the sale or disposition of a Subsidiary
Guarantor (by merger, consolidation, the sale of its Capital Stock or the sale
of all or substantially all of its assets (other than by lease)) and whether or
not the Subsidiary Guarantor is the surviving corporation in such transaction to
a Person which is not the Company or a Restricted Subsidiary of the Company
(other than a Receivables Entity), which sale or disposition is otherwise in
compliance with this Indenture (including, without limitation, SECTIONS 3.4, 3.7
and 3.10), such Subsidiary Guarantor will be deemed released from all its
obligations under this Indenture and its Notes Guarantee and such Notes
Guarantee will terminate; PROVIDED, HOWEVER, that any such termination will
occur only to the extent that all obligations of such Subsidiary Guarantor under
the Senior Credit Agreement and all of its guarantees of, and under all of its
pledges of assets or other security interests which secure, any other
Indebtedness of the Company or its Restricted Subsidiaries will also terminate
upon such release, sale or transfer.

                                                                             113

            (c)      Each Guarantor will be deemed released from all its
obligations under this Indenture, its Notes Guarantee and the Registration
Rights Agreement and such Notes Guarantee will terminate upon the legal
defeasance or covenant defeasance of the Securities pursuant to the provisions
of ARTICLE VIII hereof.

            (d)      A Subsidiary Guarantor will be deemed released and relieved
of its obligations under this Indenture and its Notes Guarantee without any
further action required on the part of the Company or such Subsidiary Guarantor
upon the designation of such Subsidiary Guarantor as an Unrestricted Subsidiary
in accordance with the terms of this Indenture.

            SECTION 11.3. RIGHT OF CONTRIBUTION. Each Guarantor hereby agrees
that to the extent that any Guarantor shall have paid more than its
proportionate share of any payment made on the obligations under the Notes
Guarantees, such Guarantor shall be entitled to seek and receive contribution
from and against the Company or any other Guarantor who has not paid its
proportionate share of such payment. Each Guarantor's right of contribution
shall be subject to the terms and conditions of SECTION 3.6. The provisions of
this SECTION 11.3 shall in no respect limit the obligations and liabilities of
each Guarantor to the Trustee and the Holders and each Guarantor shall remain
liable to the Trustee and the Holders for the full amount guaranteed by such
Guarantor hereunder.

            SECTION 11.4. NO SUBROGATION. Notwithstanding any payment or
payments made by each Guarantor hereunder, no Guarantor shall be entitled to be
subrogated to any of the rights of the Trustee or any Holder against the Company
or any other Guarantor or any collateral security or guarantee or right of
offset held by the Trustee or any Holder for the payment of the Obligations, nor
shall any Guarantor seek or be entitled to seek any contribution or
reimbursement from the Company or any other Guarantor in respect of payments
made by such Guarantor hereunder, until all amounts owing to the Trustee and the
Holders by the Company on account of the Obligations are paid in full. If any
amount shall be paid to any Guarantor on account of such subrogation rights at
any time when all of the Obligations shall not have been paid in full, such
amount shall be held by such Guarantor in trust for the Trustee and the Holders,
segregated from other funds of such Guarantor, and shall, forthwith upon receipt
by such Guarantor, be turned over to the Trustee in the exact form received by
such Guarantor (duly indorsed by such Guarantor to the Trustee, if required), to
be applied against the Obligations.

                                   ARTICLE XII

                        SUBORDINATION OF NOTES GUARANTEES

            SECTION 12.1. AGREEMENT TO SUBORDINATE. Each Guarantor agrees, and
each Securityholder by accepting a Security agrees, that the Indebtedness
evidenced by, and all other obligations in respect of, the Notes Guarantees are
subordinated in right of payment, to the extent and in the manner provided in
this ARTICLE XII, to the prior payment of all Guarantor Senior Indebtedness of
the applicable Guarantor and that the subordination is for the benefit of and
enforceable by the holders of Guarantor Senior Indebtedness of the applicable
Guarantor. The Notes Guarantees shall in all respects rank PARI PASSU with all
other Guarantor Senior Subordinated Indebtedness of the Guarantor and only
Indebtedness of the Guarantor that is

<Page>

                                                                             114

Guarantor Senior Indebtedness will rank senior to the Notes Guarantees in
accordance with the provisions set forth herein. All provisions of this ARTICLE
XII shall be subject to SECTION 12.12.

            SECTION 12.2. LIQUIDATION, DISSOLUTION, BANKRUPTCY. Upon any payment
or distribution of the assets of any Guarantor to creditors upon a total or
partial liquidation or a total or partial dissolution of any Guarantor or in a
bankruptcy, reorganization, insolvency, receivership or similar proceeding
relating to any Guarantor or its properties:

            (1)      holders of Guarantor Senior Indebtedness of such Guarantor
     shall be entitled to receive payment in full in cash or Cash Equivalents of
     all Guarantor Senior Indebtedness of such Guarantor (including interest
     accruing after, or which would accrue but for, the commencement of any
     proceeding at the rate specified in the applicable Guarantor Senior
     Indebtedness, whether or not a claim for such interest would be allowed)
     before Securityholders shall be entitled to receive any payment of
     principal of or interest on or other amounts with respect to the Notes
     Guarantees from any Guarantor; and

            (2)      until the Guarantor Senior Indebtedness of such Guarantor
     is paid in full in cash or Cash Equivalents, any payment or distribution to
     which Securityholders would be entitled but for this ARTICLE XII shall be
     made to holders of Guarantor Senior Indebtedness of such Guarantor, as
     their respective interests may appear, except that the holders of the
     Securities may receive Capital Stock (other than Disqualified Stock) issued
     by the Company to pay interest on the Securities or issued in exchange for
     the Securities, (ii) securities substantially identical to the Securities
     issued by the Company in payment of interest thereon or (iii) securities
     issued by the Company which are subordinated to Guarantor Senior
     Indebtedness at least to the same extent as the Securities and having an
     Average Life at least equal to the remaining Average Life of the
     Securities.

            SECTION 12.3. DEFAULT ON GUARANTOR SENIOR INDEBTEDNESS. A Guarantor
shall not pay the principal of, premium (if any) or interest on or other payment
obligations in respect of the Notes Guarantees or make any deposit pursuant to
SECTION 8.2 or repurchase, redeem or otherwise retire the Notes Guarantee
(collectively, "pay the Securities") if (i) any Senior Indebtedness or Guarantor
Senior Indebtedness of the applicable Guarantor is not paid when due in cash or
Cash Equivalents or (ii) any other default on Senior Indebtedness or Guarantor
Senior Indebtedness of the applicable Guarantor occurs and the maturity of such
Senior Indebtedness or Guarantor Senior Indebtedness is accelerated in
accordance with its terms unless, in either case, (x) the default has been cured
or waived and any such acceleration has been rescinded or (y) such Senior
Indebtedness or Guarantor Senior Indebtedness of the applicable Guarantor has
been paid in full in cash or Cash Equivalents; PROVIDED, HOWEVER, that each
Guarantor may pay the Securities, without regard to the foregoing if the Company
and the Trustee receive written notice approving such payment from the
Representative of the Senior Indebtedness or Guarantor Senior Indebtedness of
the applicable Guarantor with respect to which either of the events set forth in
clause (i) or (ii) of this sentence has occurred and is continuing. During the
continuance of any default (other than a default described in clause (i) of this
sentence or a default resulting in acceleration set forth in clause (ii) of the
preceding sentence) with respect to any Designated Senior Indebtedness or
Designated Guarantor Senior Indebtedness of the applicable Guarantor pursuant to
which the maturity thereof may be accelerated immediately without further notice

<Page>

                                                                             115

(except such notice as may be required to effect such acceleration) or the
expiration of any applicable grace periods, each Guarantor may not pay the
Securities during the Payment Blockage Period (as defined in SECTION 10.3)
commencing upon the receipt by the Trustee (with a copy to the Company and the
Guarantor) of the Blockage Notice (as defined in SECTION 10.3) of such default
from the Representative(s) of the holders of Designated Senior Indebtedness or
Designated Guarantor Senior Indebtedness of the applicable Guarantor specifying
an election to effect a Payment Blockage Period and ending 179 days thereafter
(or earlier if such Payment Blockage Period is terminated (i) by written notice
to the Trustee, the Guarantor and the Company from the Person or Persons who
gave such Blockage Notice, (ii) because the default giving rise to such Blockage
Notice is no longer continuing or (iii) because such Designated Senior
Indebtedness or Designated Guarantor Senior Indebtedness has been repaid in full
in cash or Cash Equivalents). Notwithstanding the provisions of the immediately
preceding sentence, unless the holders of such Designated Senior Indebtedness or
Designated Guarantor Senior Indebtedness of the applicable Guarantor or the
Representative(s) of such holders shall have accelerated the maturity of such
Designated Senior Indebtedness or such Designated Guarantor Senior Indebtedness,
such Guarantor may resume payments on the Securities after the end of such
Payment Blockage Period (including any missed payments). Not more than one
Blockage Notice may be given, and not more than one Payment Blockage may occur,
in any consecutive 360-day period, irrespective of the number of defaults with
respect to Designated Senior Indebtedness or Designated Guarantor Senior
Indebtedness of the applicable Guarantor during such period. However, if any
Blockage Notice within such 360-day period is given by or on behalf of any
holders of Designated Senior Indebtedness other than the Bank Indebtedness, the
Representative of the Bank Indebtedness may give another Blockage Notice within
such period. In no event, however, may the total number of days during which any
Payment Blockage Period or Periods is in effect exceed 179 days in the aggregate
during any 360 consecutive day period. For purposes of this paragraph, no
default or event of default that existed or was continuing on the date of the
commencement of any Payment Blockage Period with respect to the Designated
Senior Indebtedness initiating such Payment Blockage Period shall be, or be
made, the basis of the commencement of a subsequent Payment Blockage Period by
the Representative of such Designated Senior Indebtedness, whether or not within
a period of 360 consecutive days, unless such default or event of default shall
have been cured or waived for a period of not less than 90 consecutive days.

            SECTION 12.4. ACCELERATION OF PAYMENT OF SECURITIES. If payment of
the Securities is accelerated because of an Event of Default, each Guarantor and
the Trustee shall promptly notify the holders of the Designated Senior
Indebtedness or Designated Guarantor Senior Indebtedness (or their
Representatives) of the acceleration; PROVIDED, HOWEVER, that the Company and
the Trustee shall be obligated to notify such a Representative only if such
Representative has delivered or caused to be delivered to the Company and the
Trustee an address for service of such a notice (and the Company and the Trustee
shall only be obligated to deliver the notice to the address so specified). If
any Designated Senior Indebtedness or Designated Guarantor Senior Indebtedness
is outstanding, each Guarantor shall not pay the Securities until five Business
Days after the holders or Representative(s) of such Designated Senior
Indebtedness or Designated Guarantor Senior Indebtedness of the applicable
Guarantor receives notice of such acceleration and, thereafter, may pay the
Securities, only if this ARTICLE XII otherwise permits payments at that time.

                                                                             116

            SECTION 12.5. WHEN DISTRIBUTION MUST BE PAID OVER. If a distribution
is made to Securityholders that because of this ARTICLE XII should not have been
made to them, the Securityholders who receive the distribution shall hold it in
trust for holders of Guarantor Senior Indebtedness of the applicable Guarantor
and promptly pay it over to them as their respective interests may appear.

            SECTION 12.6. SUBROGATION. After all Guarantor Senior Indebtedness
is paid in full and until the Securities are paid in full, Securityholders shall
be subrogated to the rights of holders of Guarantor Senior Indebtedness to
receive distributions applicable to Guarantor Senior Indebtedness. A
distribution made under this ARTICLE XII to holders of Guarantor Senior
Indebtedness which otherwise would have been made to Securityholders is not, as
between the Company and Securityholders, a payment by the Company of Guarantor
Senior Indebtedness.

            SECTION 12.7. RELATIVE RIGHTS. This ARTICLE XII defines the relative
rights of Securityholders and holders of Guarantor Senior Indebtedness. Nothing
in this Indenture shall:

            (1)      impair, as between Guarantor and Securityholders, the
     obligation of each Guarantor which is absolute and unconditional, to
     guarantee the payment of principal of and interest on the Securities in
     accordance with their terms; or

            (2)      prevent the Trustee or any Securityholder from exercising
     its available remedies upon a Default or Event of Default, subject to the
     rights of holders of Guarantor Senior Indebtedness to receive distributions
     otherwise payable to Securityholders.

            SECTION 12.8. SUBORDINATION MAY NOT BE IMPAIRED BY COMPANY. No right
of any holder of Guarantor Senior Indebtedness to enforce the subordination of
the Indebtedness evidenced by the Notes Guarantees shall be impaired by any act
or failure to act by any Guarantor or by the failure of any of them to comply
with this Indenture.

            SECTION 12.9. RIGHTS OF TRUSTEE AND PAYING AGENT. Notwithstanding
SECTION 12.3, the Trustee or Paying Agent may continue to make payments on the
Securities and shall not be charged with knowledge of the existence of facts
that would prohibit the making of any such payments unless, not less than two
Business Days prior to the date of such payment, a Trust Officer of the Trustee
receives notice in writing satisfactory to it that payments may not be made
under this ARTICLE XII. Each Guarantor, the Registrar, the Paying Agent, a
Representative or a holder of Senior Indebtedness may give the notice; PROVIDED,
HOWEVER, that, if an issue of Guarantor Senior Indebtedness has a
Representative, only the Representative may give the notice.

            The Trustee in its individual or any other capacity may hold
Guarantor Senior Indebtedness with the same rights it would have if it were not
Trustee. The Registrar and the Paying Agent may do the same with like rights.
The Trustee shall be entitled to all the rights set forth in this ARTICLE XII
with respect to any Guarantor Senior Indebtedness which may at any time be held
by it, to the same extent as any other holder of Guarantor Senior Indebtedness;
and nothing in ARTICLE VII shall deprive the Trustee of any of its rights as
such holder. Nothing in this ARTICLE XII shall apply to claims of, or payments
to, the Trustee under or pursuant to SECTION 7.7.

                                                                             117

            SECTION 12.10. DISTRIBUTION OR NOTICE TO REPRESENTATIVE. Whenever a
distribution is to be made or a notice given to holders of Guarantor Senior
Indebtedness, the distribution may be made and the notice given to their
Representative (if any).

            SECTION 12.11. ARTICLE XII NOT TO PREVENT EVENTS OF DEFAULT OR LIMIT
RIGHT TO ACCELERATE. The failure to make a payment in respect of the Securities
and the Notes Guarantees, by reason of any provision in this ARTICLE XII shall
not be construed as preventing the occurrence of a Default or Event of Default.
Nothing in this ARTICLE XII shall have any effect on the right of the
Securityholders or the Trustee to accelerate the maturity of the Securities.

            SECTION 12.12. TRUST MONEYS NOT SUBORDINATED. Notwithstanding
anything contained herein to the contrary, payments from money or the proceeds
of U.S. Government Obligations held in trust under ARTICLE VIII by the Trustee
for the payment of principal of and interest on the Securities or the Notes
Guarantees shall not be subordinated to the prior payment of any Guarantor
Senior Indebtedness or subject to the restrictions set forth in this ARTICLE
XII, and none of the Securityholders shall be obligated to pay over any such
amount to the Company, any holder of Guarantor Senior Indebtedness, or any other
creditor of such Guarantor.

            SECTION 12.13. TRUSTEE ENTITLED TO RELY. Upon any payment or
distribution pursuant to this ARTICLE XII, the Trustee and the Securityholders
shall be entitled to rely (i) upon any order or decree of a court of competent
jurisdiction in which any proceedings of the nature referred to in SECTION 12.2
are pending, (ii) upon a certificate of the liquidating trustee or agent or
other Person making such payment or distribution to the Trustee or to the
Securityholders or (iii) upon the Representatives for the holders of Guarantor
Senior Indebtedness for the purpose of ascertaining the Persons entitled to
participate in such payment or distribution, the holders of Guarantor Senior
Indebtedness and other Indebtedness of each Guarantor, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts pertinent thereto or to this ARTICLE XII. In the event that the Trustee
determines, in good faith, that evidence is required with respect to the right
of any Person as a holder of Guarantor Senior Indebtedness to participate in any
payment or distribution pursuant to this ARTICLE XII, the Trustee may request
such Person to furnish evidence to the reasonable satisfaction of the Trustee as
to the amount of Guarantor Senior Indebtedness held by such Person, the extent
to which such Person is entitled to participate in such payment or distribution
and other facts pertinent to the rights of such Person under this ARTICLE XII,
and, if such evidence is not furnished, the Trustee may defer any payment to
such Person pending judicial determination as to the right of such Person to
receive such payment. The provisions of SECTIONS 7.1 and 7.2 shall be applicable
to all actions or omissions of actions by the Trustee pursuant to this ARTICLE
XII.

            SECTION 12.14. TRUSTEE TO EFFECTUATE SUBORDINATION. Each
Securityholder by accepting a Security authorizes and directs the Trustee on its
behalf to take such action as may be necessary or appropriate to acknowledge or
effectuate the subordination between the Securityholders and the holders of
Guarantor Senior Indebtedness as provided in this ARTICLE XII and appoints the
Trustee as attorney-in-fact for any and all such purposes.

            SECTION 12.15. TRUSTEE NOT FIDUCIARY FOR HOLDERS OF GUARANTOR SENIOR
INDEBTEDNESS. The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Guarantor Senior Indebtedness and shall not be liable to any such
holders if it shall mistakenly

Indebtedness.

appears on the registration books of the Registrar and shall be sufficiently
given if so mailed within the time prescribed.

            Failure to mail a notice or communication to a Securityholder or any

            SECTION 13.4. CERTIFICATE AND OPINION AS TO CONDITIONS PRECEDENT.
Upon any request or application by the Company to the Trustee to take or refrain

     satisfactory to the Trustee stating that, in the opinion of the signers,

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

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

            In giving such Opinion of Counsel, counsel may rely as to factual
matters on an Officers' Certificate or on certificates of public officials.

            SECTION 13.6. WHEN SECURITIES DISREGARDED. In determining whether
the Holders of the required principal amount of Securities have concurred in any
direction, waiver or consent, Securities 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 disregarded and deemed not to be
outstanding, except that, for the purpose of determining whether the Trustee
shall be protected in relying on any such direction, waiver or consent, only
Securities which the Trustee knows are so owned shall be so disregarded. Also,
subject to the foregoing, only Securities outstanding at the time shall be
considered in any such determination.

            SECTION 13.7. RULES BY TRUSTEE, PAYING AGENT AND REGISTRAR. The
Trustee may make reasonable rules for action by, or a meeting of,
Securityholders. The Registrar and the Paying Agent may make reasonable rules
for their functions.

            SECTION 13.8. LEGAL HOLIDAYS. A "Legal Holiday" is a Saturday, a
Sunday or other day on which commercial banking institutions are authorized or
required to be closed in New York City. If a payment date is a Legal Holiday,
payment shall be made on the next succeeding day that is not a Legal Holiday,
and no interest shall accrue for the intervening period. If a regular record
date is a Legal Holiday, the record date shall not be affected.

            SECTION 13.9. GOVERNING LAW. THIS INDENTURE AND THE SECURITIES SHALL
BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW

director, officer, employee, stockholder or controlling person, as such, of the
Company or any Guarantor shall not have any liability for any obligations of the
Company or any Guarantor under the Securities, this Indenture or the Notes
Guarantees or for any claim based on, in respect of or by reason of such
obligations or their creation. By accepting a Security, each Securityholder
shall waive and release all such liability. The waiver and release shall be part
of the consideration for the issue of the Securities.

            SECTION 13.11. SUCCESSORS. All agreements of the Company in this
Indenture and the Securities shall bind their respective successors. All
agreements of the Trustee in this Indenture shall bind its successors.

            SECTION 13.12. MULTIPLE 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. One signed copy is enough to prove
this Indenture.

                     [FORM OF REVERSE SIDE OF SERIES A NOTE]

              11 7/8% Senior Subordinated Note, Series A, due 2012

1. INTEREST

            MedQuest, Inc., a Delaware corporation (such corporation, and its
successors and assigns under the Indenture hereinafter referred to, being herein
called the "Company"), promises to pay interest on the principal amount of this
Security at the rate per annum shown above.

            The Company will pay interest semiannually on February 15 and August
15 of each year commencing February 15, 2003. Interest on the Securities will
accrue from the most recent date to which interest has been paid on the
Securities or, if no interest has been paid, from August 15, 2002. The Company
shall pay interest on overdue principal or premium, if any (plus interest on
such interest to the extent lawful), at the rate borne by the Securities to the
extent lawful. Interest will be computed on the basis of a 360-day year of
twelve 30-day months.

2. METHOD OF PAYMENT

            By no later than 10:00 a.m. (New York City time) on the date on
which any principal of or interest on any Security is due and payable, the
Company shall irrevocably deposit with the Trustee or the Paying Agent money
sufficient to pay such principal, premium, if any, and/or interest. The Company
will pay interest (except Defaulted Interest) to the Persons who are registered
Holders of Securities at the close of business on the February 1 or August 1
next preceding the interest payment date even if Securities are cancelled,
repurchased or redeemed after the record date and on or before the interest
payment date. Holders must surrender Securities to a Paying Agent to collect
principal payments. The Company will pay principal and interest in money of the
United States that at the time of payment is legal tender for payment of public
and private debts. Payments in respect of Securities represented by a Global
Security (including principal, premium, if any, and interest) will be made by
the transfer of immediately available funds to the accounts specified by The
Depository Trust Company. The Company will make all payments in respect of a
Definitive Security (including principal, premium, if any, and interest) by
mailing a check to the registered address of each Holder thereof; PROVIDED,
HOWEVER, that payments on the Securities may also be made, in the case of a
Holder of a least $1,000,000 aggregate principal amount of Securities, by wire
transfer to a U.S. dollar account maintained by the payee with a bank in the
United States if such Holder elects payment by wire transfer by giving written
notice to the Trustee or the Paying Agent to such effect designating such
account no later than 15 days immediately preceding the relevant due date for
payment (or such other date as the Trustee may accept in its discretion).

3. PAYING AGENT AND REGISTRAR

            Initially, Wachovia Bank, National Association (the "Trustee"), will
act as Trustee, Paying Agent and Registrar. The Company may appoint and change
any Paying Agent, Registrar or co-registrar without notice to any
Securityholder. The Company or any of its Restricted Subsidiaries may act as
Paying Agent, Registrar or co-registrar.

                                       A-2

4. INDENTURE

            The Company issued the Securities under an Indenture dated as of
August 15, 2002 (as it may be amended or supplemented from time to time in
accordance with the terms thereof, the "Indenture"), among the Company, MQ
Associates, Inc. ("Holdings"), the Subsidiary Guarantors and the Trustee. The
terms of the Securities include those stated in the Indenture and those made
part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C.
Sections 77aaa-77bbbb) as in effect on the date of the Indenture (the "Act").
Capitalized terms used herein and not defined herein have the meanings ascribed
thereto in the Indenture. The Securities are subject to all such terms, and
Securityholders are referred to the Indenture and the Act for a statement of
those terms.

            The Securities are general unsecured senior subordinated obligations
of the Company. The aggregate principal amount of securities that may be
authenticated and delivered under the Indenture is unlimited. This Security is
one of the 11 7/8% Senior Subordinated Notes, Series A, due 2012 referred to in
the Indenture. The Securities include (i) $180,000,000 aggregate principal
amount of the Company's 11 7/8% Senior Subordinated Notes, Series A, due 2012
issued under the Indenture on August 15, 2002 (herein called "Initial
Securities"), (ii) if and when issued, additional 11 7/8% Senior Subordinated
Notes, Series A, due 2012 or 11 7/8% Senior Subordinated Notes, Series B, due
2012 of the Company that may be issued from time to time under the Indenture
subsequent to August 15, 2002 (herein called "Additional Securities") and (iii)
if and when issued, the Company's 11 7/8% Senior Subordinated Notes, Series B,
due 2012 that may be issued from time to time under the Indenture in exchange
for Initial Securities or Additional Securities in an offer registered under the
Securities Act as provided in the Registration Rights Agreement (herein called
"Exchange Securities"). The Initial Securities, Additional Securities and
Exchange Securities are treated as a single class of securities under the
Indenture. The Indenture imposes certain limitations on, among other things, the
Incurrence of Indebtedness by the Company and its Subsidiaries, the payment of
dividends and other distributions on the Capital Stock of the Company and its
Subsidiaries, the purchase or redemption of Capital Stock of the Company,
certain purchases or redemptions of Subordinated Indebtedness, the sale or
transfer of assets and Capital Stock of Restricted Subsidiaries, the issuance or
sale of Capital Stock of Restricted Subsidiaries, the incurrence of certain
liens, certain payment guarantees, the business activities and investments of
the Company and its Restricted Subsidiaries, mergers and consolidation, and
transactions with Affiliates. In addition, the Indenture limits the ability of
the Company and its Restricted Subsidiaries to enter into agreements that
restrict distributions and dividends from Restricted Subsidiaries.

            To guarantee the due and punctual payment of the principal, premium,
if any, and interest on the Securities and all other amounts payable by the
Company under the Indenture and the Securities when and as the same shall be due
and payable, whether at maturity, by acceleration or otherwise, according to the
terms of the Securities and the Indenture, the Guarantors have unconditionally
guaranteed (and future Subsidiary Guarantors, together with the Guarantors, will
unconditionally guarantee), jointly and severally, such obligations on a senior
subordinated basis pursuant to the terms of the Indenture.

the Securities must remain outstanding after each such redemption; PROVIDED
FURTHER, that each such redemption occurs within 120 days of the date of closing
of such Equity Offering.

            If the optional redemption date is on or after an interest record
date and on or before the related interest payment date, the accrued and unpaid
interest, if any, will be paid to the Person in whose name the Security is
registered at the close of business on such record date, and no additional
interest will be payable to Holders whose Securities will be subject to
redemption by the Company.

            In the case of any partial redemption, selection of the Securities
for redemption will be made by the Trustee in compliance with the requirements
of the principal national securities exchange, if any, on which the Securities
are listed or, if the Securities are not listed, then on a pro rata basis, by
lot or by such other method as the Trustee in its sole discretion shall deem to
be fair and appropriate, although no Securities of $1,000 in original principal
amount or less will be redeemed in part. Any such notice to the Trustee may be
cancelled at any time prior to notice of such redemption being mailed to any
Holder and shall thereby be void and of no effect. If any Security is to be
redeemed in part only, the notice of redemption relating to such

                                       A-4
<Page>

Security shall state the portion of the principal amount thereof to be redeemed.
A new Security in principal amount equal to the unredeemed portion thereof will
be issued in the name of the Holder thereof upon cancellation of the original
Security. On and after the redemption date, interest will cease to accrue on
Securities or portions thereof called for redemption as long as the Company has
deposited with the Paying Agent funds in satisfaction of the applicable
redemption price pursuant to the Indenture.

            In addition, at any time prior to August 15, 2007, within 90 days
following the occurrence of a Change of Control, the Company may redeem the
Securities, in whole but not in part, at a redemption price equal to 100% of the
principal amount thereof plus the Applicable Premium plus accrued and unpaid
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 the relevant
interest payment date). Notice of redemption of the Securities pursuant to this
paragraph shall be mailed to holders of the Securities not more than 60 days
following the occurrence of a Change of Control, which notice shall state the
redemption date (which shall be no earlier than 30 days nor later than 60 days
from the date such notice is mailed).

6. REPURCHASE PROVISIONS

            (a) Upon a Change of Control any Holder of Securities will have the
right to cause the Company to repurchase all or any part of the Securities of
such Holder at a purchase price in cash equal to 101% of the principal amount
thereof, plus accrued and unpaid interest, if any, to the date of repurchase
(subject to the right of Holders of record on the relevant record date to
receive interest due on the relevant interest payment date) as provided in, and
subject to the terms of, the Indenture.

            (b) In the event of an Asset Disposition that requires the purchase
of Securities pursuant to SECTION 3.7(b) of the Indenture, the Company will be
required to apply such Excess Proceeds to the repayment of the Securities and
any Pari Passu Notes in accordance with the procedures set forth in SECTION 3.7
of the Indenture.

7. SUBORDINATION

            The Securities are subordinated to Senior Indebtedness, as defined
in the Indenture. To the extent provided in the Indenture, Senior Indebtedness
must be paid before the Securities may be paid. The Company agrees, and each
Securityholder by accepting a Security agrees, to the subordination provisions
contained in the Indenture and authorizes the Trustee to give them effect and
appoints the Trustee as attorney-in-fact for such purpose.

8. DENOMINATIONS; TRANSFER; EXCHANGE

            The Securities are in registered form without coupons in
denominations of principal amount of $1,000 and whole multiples of $1,000. A
Holder may transfer or exchange Securities in accordance with the Indenture. The
Registrar may require a Holder, among other things, to furnish appropriate
endorsements or transfer documents and to pay any taxes and fees required by law
or permitted by the Indenture. The Registrar need not register the transfer of
or exchange (i) any Securities selected for redemption (except, in the case of a
Security to be redeemed in part, the portion of the Security not to be redeemed)
for a period beginning 15 days

                                       A-5
<Page>

before the mailing of a notice of Securities to be redeemed and ending on the
date of such mailing or (ii) any Securities for a period beginning 15 days
before an interest payment date and ending on such interest payment date.

9. PERSONS DEEMED OWNERS

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

10. UNCLAIMED MONEY

            If money for the payment of principal or interest remains unclaimed
for two years, the Trustee or Paying Agent shall pay the money back to the
Company at its request unless an abandoned property law designates another
Person. After any such payment, Holders entitled to the money must look only to
the Company and not to the Trustee for payment.

11. DEFEASANCE

            Subject to certain conditions set forth in the Indenture, the
Company at any time may terminate some or all of its obligations under the
Securities and the Indenture if the Company deposits with the Trustee money or
U.S. Government Obligations for the payment of principal and interest on the
Securities to redemption or maturity, as the case may be.

12. AMENDMENT, WAIVER

            Subject to certain exceptions set forth in the Indenture, (i) the
Indenture or the Securities may be amended with the written consent of the
Holders of at least a majority in principal amount of the then outstanding
Securities and (ii) any default (other than with respect to nonpayment or in
respect of a provision that cannot be amended without the written consent of
each Securityholder affected) or noncompliance with any provision may be waived
with the written consent of the Holders of a majority in principal amount of the
then outstanding Securities. Subject to certain exceptions set forth in the
Indenture, without the consent of any Securityholder, the Company, the
Guarantors and the Trustee may amend the Indenture or the Securities to cure any
ambiguity, omission, defect or inconsistency, or to comply with ARTICLE IV of
the Indenture, or to provide for uncertificated Securities in addition to or in
place of certificated Securities, or to add guarantees with respect to the
Securities, to release a Guarantor in accordance with the Indenture or to secure
the Securities, or to add additional covenants of the Company and the
Guarantors, or surrender rights and powers conferred on the Company, or to
comply with any request of the SEC in connection with qualifying the Indenture
under the Act, or to make any change that does not adversely affect the rights
of any Securityholder, or to provide for the issuance of Exchange Securities.

13. DEFAULTS AND REMEDIES

            Under the Indenture, Events of Default include (i) default for 30
days in payment of interest or additional interest when due on the Securities,
whether or not such payment is prohibited by ARTICLE X or XII of the Indenture;
(ii) default in payment of principal or premium, if any, on the Securities at
Stated Maturity, upon required repurchase or upon optional

                                       A-6
<Page>

redemption pursuant to paragraphs 5 and 6 of the Securities, upon declaration or
otherwise, whether or not such payment is prohibited by ARTICLE X or XII of the
Indenture; (iii) the failure by the Company or any Guarantor to comply with its
obligations under ARTICLE IV or SECTION 11.2 of the Indenture; (iv) failure by
the Company to comply for 30 days after notice with any of its obligations under
the covenants described under SECTIONS 3.2 through 3.17 inclusive of the
Indenture (in each case, other than a failure to purchase Securities when
required pursuant to SECTION 3.7 or 3.9, which failure shall constitute an Event
of Default under clause (ii) above and other than a failure to comply with
ARTICLE IV or SECTION 11.2 which is covered by clause (iii) above); (v) the
failure by the Company to comply for 60 days after written notice (specifying
the default and demanding that the same be remedied) with its other agreements
contained in the Indenture or under the Securities (other than those referred to
in (i), (ii), (iii) or (iv) above); (vi) default under any mortgage, indenture
or instrument under which there may be issued or by which there may be secured
or evidenced any Indebtedness for money borrowed by the Company or any of its
Restricted Subsidiaries (or the payment of which is guaranteed by the Company or
any of its Restricted Subsidiaries), other than Indebtedness owed to the Company
or a Restricted Subsidiary, whether such Indebtedness or guarantee now exists,
or is created after the date of the Indenture, which default (a) is caused by a
failure to pay principal of, or interest or premium, if any, on such
Indebtedness after final maturity (after giving effect to any applicable grace
period provided in such Indebtedness) ("PAYMENT DEFAULT") or (b) results in the
acceleration of such Indebtedness prior to its maturity (the "CROSS ACCELERATION
PROVISION") and, in each case, the principal amount of any such Indebtedness,
together with the principal amount of any other such Indebtedness under which
there has been a payment default or the maturity of which has been so
accelerated, aggregates $10.0 million or more or its foreign currency equivalent
at the time; (vii) certain events of bankruptcy, insolvency or reorganization of
the Company or a Significant Subsidiary (other than any Receivables Entity) or
group of Restricted Subsidiaries (other than any Receivables Entity) that, taken
together (as of the latest audited consolidated financial statements for
Holdings, the Company and its Restricted Subsidiaries), would constitute a
Significant Subsidiary (the "BANKRUPTCY PROVISIONS"); (viii) failure by the
Company or any Significant Subsidiary or group of Restricted Subsidiaries that,
taken together (as of the latest audited consolidated financial statements for
Holdings, the Company and its Restricted Subsidiaries), would constitute a
Significant Subsidiary to pay final judgments aggregating in excess of $10.0
million or its foreign currency equivalent at the time (net of any amounts with
respect to which a reputable and creditworthy insurance company has acknowledged
liability or coverage for in writing), which judgments are not paid, discharged
or stayed for a period of 60 days (the "JUDGMENT DEFAULT PROVISION") or (ix) any
Notes Guarantee of Holdings, a Significant Subsidiary, or a group of Subsidiary
Guarantors that, taken together (as of the latest audited consolidated financial
statements for Holdings the Company and its Restricted Subsidiaries), would
collectively represent a Significant Subsidiary ceases to be in full force and
effect (except as contemplated by the terms of the Indenture) or is declared
null and void in a judicial proceeding or any Guarantor denies or disaffirms its
obligations under the Indenture or its Notes Guarantee. However, a default under
clauses (iv) and (v) will not constitute an Event of Default until the Trustee
or the Holders of 25% or more in principal amount of the outstanding Securities
notify the Company of the default and the Company does not cure such default
within the time specified in clauses (iv) and (v) hereof after receipt of such
notice.

                                       A-7
<Page>

            If an Event of Default occurs and is continuing, the Trustee or the
Holders of at least 25% in principal amount of the Securities may declare all
the Securities to be due and payable immediately. Certain events of bankruptcy
or insolvency are Events of Default which will result in the Securities being
due and payable immediately upon the occurrence of such Events of Default.

            Securityholders may not enforce the Indenture or the Securities
except as provided in the Indenture. The Trustee may refuse to enforce the
Indenture or the Securities unless it receives reasonable indemnity or security.
Subject to certain limitations, Holders of a majority in principal amount of the
Securities may direct the Trustee in its exercise of any trust or power. The
Trustee may withhold from Securityholders notice of any continuing Default or
Event of Default (except a Default or Event of Default in payment of principal
or interest) if it determines that withholding notice is in their interest.

14. TRUSTEE DEALINGS WITH THE COMPANY

            Subject to certain limitations set forth in the Indenture, the
Trustee under the Indenture, in its individual or any other capacity, may become
the owner or pledgee of Securities and may otherwise deal with and collect
obligations owed to it by the Company or its Affiliates and may otherwise deal
with the Company or its affiliates with the same rights it would have if it were
not Trustee.

15. NO RECOURSE AGAINST OTHERS

            An incorporator, director, officer, employee, stockholder or
controlling person, as such, of each of the Company or any Guarantor shall not
have any liability for any obligations of the Company under the Securities, the
Indenture or any Notes Guarantees or for any claim based on, in respect of or by
reason of such obligations or their creation. By accepting a Security, each
Securityholder waives and releases all such liability. The waiver and release
are part of the consideration for the issue of the Securities.

16. AUTHENTICATION

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

17. ABBREVIATIONS

            Customary abbreviations may be used in the name of a Securityholder

              11 7/8% Senior Subordinated Note, Series B, due 2012

1. INTEREST

            MedQuest, Inc., a Delaware corporation (such corporation, and its
successors and assigns under the Indenture hereinafter referred to, being herein
called the "Company"), promises to pay interest on the principal amount of this
Security at the rate per annum shown above.

            The Company will pay interest semiannually on February 15 and August
15 of each year commencing February 15, 2003. Interest on the Securities will
accrue from the most recent date to which interest has been paid on the
Securities or, if no interest has been paid, from August 15, 2002. The Company
shall pay interest on overdue principal or premium, if any (plus interest on
such interest to the extent lawful), at the rate borne by the Securities to the
extent lawful. Interest will be computed on the basis of a 360-day year of
twelve 30-day months.

2. METHOD OF PAYMENT

            By no later than 10:00 a.m. (New York City time) on the date on
which any principal of or interest on any Security is due and payable, the
Company shall irrevocably deposit with the Trustee or the Paying Agent money
sufficient to pay such principal, premium, if any, and/or interest. The Company
will pay interest (except Defaulted Interest) to the Persons who are registered
Holders of Securities at the close of business on the February 1 or August 1
next preceding the interest payment date even if Securities are cancelled,
repurchased or redeemed after the record date and on or before the interest
payment date. Holders must surrender Securities to a Paying Agent to collect
principal payments. The Company will pay principal and interest in money of the
United States that at the time of payment is legal tender for payment of public
and private debts. Payments in respect of Securities represented by a Global
Security (including principal, premium, if any, and interest) will be made by
the transfer of immediately available funds to the accounts specified by The
Depository Trust Company. The Company will make all payments in respect of a
Definitive Security (including principal, premium, if any, and interest) by

HOWEVER, that payments on the Securities may also be made, in the case of a
Holder of a least $1,000,000 aggregate principal amount of Securities, by wire
transfer to a U.S. dollar account maintained by the payee with a bank in the
United States if such Holder elects payment by wire transfer by giving written
notice to the Trustee or the Paying Agent to such effect designating such
account no later than 15 days immediately preceding the relevant due date for
payment (or such other date as the Trustee may accept in its discretion).

3. PAYING AGENT AND REGISTRAR

            Initially, Wachovia Bank, National Association (the "Trustee"), will
act as Trustee, Paying Agent and Registrar. The Company may appoint and change
any Paying Agent, Registrar or co-registrar without notice to any

4. INDENTURE

            The Company issued the Securities under an Indenture dated as of
August 15, 2002 (as it may be amended or supplemented from time to time in
accordance with the terms thereof, the "Indenture"), among the Company, MQ
Associates, Inc. ("Holdings"), the Subsidiary Guarantors and the Trustee. The
terms of the Securities include those stated in the Indenture and those made
part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C.
Sections 77aaa-77bbbb) as in effect on the date of the Indenture (the "Act").
Capitalized terms used herein and not defined herein have the meanings ascribed
thereto in the Indenture. The Securities are subject to all such terms, and
Securityholders are referred to the Indenture and the Act for a statement of
those terms.

            The Securities are general unsecured senior subordinated obligations
of the Company. The aggregate principal amount of securities that may be
authenticated and delivered under the Indenture is unlimited. This Security is
one of the 11 7/8% Senior Subordinated Notes, Series B, due 2012 referred to in
the Indenture. The Securities include (i) $180,000,000 aggregate principal
amount of the Company's 11 7/8% Senior Subordinated Notes, Series A, due 2012
issued under the Indenture on August 15, 2002 (herein called "Initial
Securities"), (ii) if and when issued, additional 11 7/8% Senior Subordinated
Notes, Series A, due 2012 or 11 7/8% Senior Subordinated Notes, Series B, due
2012 of the Company that may be issued from time to time under the Indenture
subsequent to August 15, 2002 (herein called "Additional Securities") and (iii)
if and when issued, the Company's 11 7/8% Senior Subordinated Notes, Series B,
due 2012 that may be issued from time to time under the Indenture in exchange
for Initial Securities or Additional Securities in an offer registered under the
Securities Act as provided in the Registration Rights Agreement (herein called
"Exchange Securities"). The Initial Securities, Additional Securities and
Exchange Securities are treated as a single class of securities under the
Indenture. The Indenture imposes certain limitations on, among other things, the
Incurrence of Indebtedness by the Company and its Subsidiaries, the payment of
dividends and other distributions on the Capital Stock of the Company and its
Subsidiaries, the purchase or redemption of Capital Stock of the Company,
certain purchases or redemptions of Subordinated Indebtedness, the sale or
transfer of assets and Capital Stock of Restricted Subsidiaries, the issuance or
sale of Capital Stock of Restricted Subsidiaries, the incurrence of certain
liens, certain payment guarantees, the business activities and investments of
the Company and its Restricted Subsidiaries, mergers and consolidations, and
transactions with Affiliates. In addition, the Indenture limits the ability of
the Company and its Restricted Subsidiaries to enter into agreements that
restrict distributions and dividends from Restricted Subsidiaries.

            To guarantee the due and punctual payment of the principal, premium,
if any, and interest on the Securities and all other amounts payable by the
Company under the Indenture and the Securities when and as the same shall be due
and payable, whether at maturity, by acceleration or otherwise, according to the
terms of the Securities and the Indenture, the Guarantors have unconditionally
guaranteed (and future Subsidiary Guarantors, together with the Guarantors, will
unconditionally guarantee), jointly and severally, such obligations on a senior
subordinated basis pursuant to the terms of the Indenture.

5. REDEMPTION

            Except as set forth below, the Securities will not be redeemable at
the option of the Company prior to August 15, 2007. On and after such date, the
Securities will be redeemable, at the Company's option, in whole or in part, at
any time upon not less than 30 nor more than 60 days prior notice mailed by
first-class mail to each Holder's registered address, at the following
redemption prices (expressed in percentages of principal amount), plus accrued
and unpaid interest to the redemption date (subject to the right of Holders of
record on the relevant record date to receive interest due on the relevant
interest payment date):

            If redeemed during the 12-month period commencing on August 15 of
the years set forth below:

<Table>

                                                                  REDEMPTION

   2007                                                            105.938%
   2008                                                            103.958%
   2009                                                            101.979%
   2010 and thereafter                                             100.000%
</Table>

            In addition, at any time and from time to time prior to August 15,
2005, the Company may redeem in the aggregate up to 35% of the original
principal amount of the Securities with the Net Cash Proceeds of one or more
Equity Offerings received by the Company at a redemption price (expressed as a
percentage of principal amount) of 111.875% plus accrued and unpaid 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 the relevant interest payment
date); PROVIDED, HOWEVER, that at least 65% of the original principal amount of
the Securities must remain outstanding after each such redemption; PROVIDED
FURTHER, that each such redemption occurs within 120 days of the date of closing
of such Equity Offering.

            If the optional redemption date is on or after an interest record
date and on or before the related interest payment date, the accrued and unpaid
interest, if any, will be paid to the Person in whose name the Security is
registered at the close of business on such record date, and no additional
interest will be payable to Holders whose Securities will be subject to
redemption by the Company.

            In the case of any partial redemption, selection of the Securities
for redemption will be made by the Trustee in compliance with the requirements
of the principal national securities exchange, if any, on which the Securities
are listed or, if the Securities are not listed, then on a pro rata basis, by
lot or by such other method as the Trustee in its sole discretion shall deem to
be fair and appropriate, although no Securities of $1,000 in original principal
amount or less will be redeemed in part. Any such notice to the Trustee may be
cancelled at any time prior to notice of such redemption being mailed to any
Holder and shall thereby be void and of no effect. If any Security is to be
redeemed in part only, the notice of redemption relating to such Security shall
state the portion of the principal amount thereof to be redeemed. A new Security
in principal amount equal to the unredeemed portion thereof will be issued in
the name of the

                                       B-4
<Page>

Holder thereof upon cancellation of the original Security. On and after the
redemption date, interest will cease to accrue on Securities or portions thereof
called for redemption as long as the Company has deposited with the Paying Agent
funds in satisfaction of the applicable redemption price pursuant to the
Indenture.

            In addition, at any time prior to August 15, 2007, within 90 days
following the occurrence of a Change of Control, the Company may redeem the
Securities, in whole but not in part, at a redemption price equal to 100% of the
principal amount thereof plus the Applicable Premium plus accrued and unpaid
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 the relevant
interest payment date). Notice of redemption of the Securities pursuant to this
paragraph shall be mailed to holders of the Securities not more than 60 days
following the occurrence of a Change of Control, which notice shall state the
redemption date (which shall be no earlier than 30 days nor later than 60 days
from the date such notice is mailed).

6. REPURCHASE PROVISIONS

            (a) Upon a Change of Control any Holder of Securities will have the
right to cause the Company to repurchase all or any part of the Securities of
such Holder at a purchase price in cash equal to 101% of the principal amount
thereof, plus accrued and unpaid interest, if any, to the date of repurchase
(subject to the right of Holders of record on the relevant record date to
receive interest due on the relevant interest payment date) as provided in, and
subject to the terms of, the Indenture.

            (b) In the event of an Asset Disposition that requires the purchase
of Securities pursuant to SECTION 3.7(b) of the Indenture, the Company will be
required to apply such Excess Proceeds to the repayment of the Securities and
any Pari Passu Notes in accordance with the procedures set forth in SECTION 3.7
of the Indenture.

7. SUBORDINATION

            The Securities are subordinated to Senior Indebtedness, as defined
in the Indenture. To the extent provided in the Indenture, Senior Indebtedness
must be paid before the Securities may be paid. The Company agrees, and each
Securityholder by accepting a Security agrees, to the subordination provisions
contained in the Indenture and authorizes the Trustee to give them effect and
appoints the Trustee as attorney-in-fact for such purpose.

8. DENOMINATIONS; TRANSFER; EXCHANGE

            The Securities are in registered form without coupons in
denominations of principal amount of $1,000 and whole multiples of $1,000. A
Holder may transfer or exchange Securities in accordance with the Indenture. The
Registrar may require a Holder, among other things, to furnish appropriate
endorsements or transfer documents and to pay any taxes and fees required by law
or permitted by the Indenture. The Registrar need not register the transfer of
or exchange (i) any Securities selected for redemption (except, in the case of a
Security to be redeemed in part, the portion of the Security not to be redeemed)
for a period beginning 15 days before the mailing of a notice of Securities to
be redeemed and ending on the date of such

                                       B-5
<Page>

mailing or (ii) any Securities for a period beginning 15 days before an interest
payment date and ending on such interest payment date.

9. PERSONS DEEMED OWNERS

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

10. UNCLAIMED MONEY

            If money for the payment of principal or interest remains unclaimed
for two years, the Trustee or Paying Agent shall pay the money back to the
Company at its request unless an abandoned property law designates another
Person. After any such payment, Holders entitled to the money must look only to
the Company and not to the Trustee for payment.

11. DEFEASANCE

            Subject to certain conditions set forth in the Indenture, the
Company at any time may terminate some or all of its obligations under the
Securities and the Indenture if the Company deposits with the Trustee money or
U.S. Government Obligations for the payment of principal and interest on the
Securities to redemption or maturity, as the case may be.

12. AMENDMENT, WAIVER

            Subject to certain exceptions set forth in the Indenture, (i) the
Indenture or the Securities may be amended with the written consent of the
Holders of at least a majority in principal amount of the then outstanding
Securities and (ii) any default (other than with respect to nonpayment or in
respect of a provision that cannot be amended without the written consent of
each Securityholder affected) or noncompliance with any provision may be waived
with the written consent of the Holders of a majority in principal amount of the
then outstanding Securities. Subject to certain exceptions set forth in the
Indenture, without the consent of any Securityholder, the Company, the
Guarantors and the Trustee may amend the Indenture or the Securities to cure any
ambiguity, omission, defect or inconsistency, or to comply with ARTICLE IV of
the Indenture, or to provide for uncertificated Securities in addition to or in
place of certificated Securities, or to add guarantees with respect to the
Securities, to release a Guarantor in accordance with the Indenture or to secure
the Securities, or to add additional covenants of the Company and the
Guarantors, or surrender rights and powers conferred on the Company, or to
comply with any request of the SEC in connection with qualifying the Indenture
under the Act, or to make any change that does not adversely affect the rights
of any Securityholder, or to provide for the issuance of Exchange Securities.

13. DEFAULTS AND REMEDIES

            Under the Indenture, Events of Default include (i) default for 30
days in payment of interest or additional interest when due on the Securities,
whether or not such payment is prohibited by ARTICLE X or XII of the Indenture;
(ii) default in payment of principal or premium, if any, on the Securities at
Stated Maturity, upon required repurchase or upon optional redemption pursuant
to paragraphs 5 and 6 of the Securities, upon declaration or otherwise,

                                       B-6
<Page>

whether or not such payment is prohibited by ARTICLE X or XII of the Indenture;
(iii) the failure by the Company or any Guarantor to comply with its obligations
under ARTICLE IV or SECTION 11.2 of the Indenture; (iv) failure by the Company
to comply for 30 days after notice with any of its obligations under the
covenants described under SECTIONS 3.2 through 3.17 inclusive of the Indenture
(in each case, other than a failure to purchase Securities when required
pursuant to SECTION 3.7 or 3.9, which failure shall constitute an Event of
Default under clause (ii) above and other than a failure to comply with ARTICLE
IV or SECTION 11.2 which is covered by clause (iii) above); (v) the failure by
the Company to comply for 60 days after written notice (specifying the default
and demanding that the same be remedied) with its other agreements contained in
the Indenture or under the Securities (other than those referred to in (i),
(ii), (iii) or (iv) above); (vi) default under any mortgage, indenture or
instrument under which there may be issued or by which there may be secured or
evidenced any Indebtedness for money borrowed by the Company or any of its
Restricted Subsidiaries (or the payment of which is guaranteed by the Company or
any of its Restricted Subsidiaries), other than Indebtedness owed to the Company
or a Restricted Subsidiary, whether such Indebtedness or guarantee now exists,
or is created after the date of the Indenture, which default (a) is caused by a
failure to pay principal of, or interest or premium, if any, on such
Indebtedness after final maturity (after giving effect to any applicable grace
period provided in such Indebtedness) ("PAYMENT DEFAULT") or (b) results in the
acceleration of such Indebtedness prior to its maturity (the "CROSS ACCELERATION
PROVISION") and, in each case, the principal amount of any such Indebtedness,
together with the principal amount of any other such Indebtedness under which
there has been a payment default or the maturity of which has been so
accelerated, aggregates $10.0 million or more or its foreign currency equivalent
at the time; (vii) certain events of bankruptcy, insolvency or reorganization of
the Company or a Significant Subsidiary (other than any Receivables Entity) or
group of Restricted Subsidiaries (other than any Receivables Entity) that, taken
together (as of the latest audited consolidated financial statements for
Holdings, the Company and its Restricted Subsidiaries), would constitute a
Significant Subsidiary (the "BANKRUPTCY PROVISIONS"); (viii) failure by the
Company or any Significant Subsidiary or group of Restricted Subsidiaries that,
taken together (as of the latest audited consolidated financial statements for
Holdings, the Company and its Restricted Subsidiaries), would constitute a
Significant Subsidiary to pay final judgments aggregating in excess of $10.0
million or its foreign currency equivalent at the time (net of any amounts with
respect to which a reputable and creditworthy insurance company has acknowledged
liability or coverage for in writing), which judgments are not paid, discharged
or stayed for a period of 60 days (the "JUDGMENT DEFAULT PROVISION") or (ix) any
Notes Guarantee of Holdings, a Significant Subsidiary, or a group of Subsidiary
Guarantors that, taken together (as of the latest audited consolidated financial
statements for Holdings the Company and its Restricted Subsidiaries), would
collectively represent a Significant Subsidiary ceases to be in full force and
effect (except as contemplated by the terms of the Indenture) or is declared
null and void in a judicial proceeding or any Guarantor denies or disaffirms its
obligations under the Indenture or its Notes Guarantee. However, a default under
clauses (iv) and (v) will not constitute an Event of Default until the Trustee
or the Holders of 25% or more in principal amount of the outstanding Securities
notify the Company of the default and the Company does not cure such default
within the time specified in clauses (iv) and (v) hereof after receipt of such
notice.

            If an Event of Default occurs and is continuing, the Trustee or the
Holders of at least 25% in principal amount of the Securities may declare all
the Securities to be due and

                                       B-7
<Page>

payable immediately. Certain events of bankruptcy or insolvency are Events of
Default which will result in the Securities being due and payable immediately
upon the occurrence of such Events of Default.

            Securityholders may not enforce the Indenture or the Securities
except as provided in the Indenture. The Trustee may refuse to enforce the
Indenture or the Securities unless it receives reasonable indemnity or security.
Subject to certain limitations, Holders of a majority in principal amount of the
Securities may direct the Trustee in its exercise of any trust or power. The
Trustee may withhold from Securityholders notice of any continuing Default or
Event of Default (except a Default or Event of Default in payment of principal
or interest) if it determines that withholding notice is in their interest.

14. TRUSTEE DEALINGS WITH THE COMPANY

            Subject to certain limitations set forth in the Indenture, the
Trustee under the Indenture, in its individual or any other capacity, may become
the owner or pledgee of Securities and may otherwise deal with and collect
obligations owed to it by the Company or its Affiliates and may otherwise deal
with the Company or its affiliates with the same rights it would have if it were
not Trustee.

15. NO RECOURSE AGAINST OTHERS

            An incorporator, director, officer, employee, stockholder or
controlling person, as such, of each of the Company or any Guarantor shall not
have any liability for any obligations of the Company under the Securities, the
Indenture or any Notes Guarantees or for any claim based on, in respect of or by
reason of such obligations or their creation. By accepting a Security, each
Securityholder waives and releases all such liability. The waiver and release
are part of the consideration for the issue of the Securities.

16. AUTHENTICATION

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

       election, not later than the close of business on the last Exchange Date,

the Exchange Securities in violation of the provisions of the Securities Act,
(iii) it is not an "affiliate" (within the meaning of Rule 405 under the

       authenticate and deliver to each Holder, Exchange Securities equal in
       principal amount to the principal amount of the Registrable Securities
       surrendered by such Holder, provided that, in the case of any Registrable
       Securities held in global form by a depositary, the delivery to such
       depositary of one or more authenticated Exchange Securities in global
       form in an equivalent principal amount for the account of such Holders or
       a nominee thereof in accordance with the Indenture shall satisfy such
       authentication and delivery requirements.

       The Company and the Guarantors shall use their reasonable best efforts to
complete the Exchange Offer as provided above and shall comply with the
applicable requirements of the Securities Act, the Exchange Act and other
applicable laws and regulations in connection with the Exchange Offer. The
Exchange Offer shall not be subject to any conditions, other than (i) that the
Exchange Offer does not violate any applicable law or applicable interpretations
of the Staff, (ii) that no action or proceeding shall have been instituted or
threatened in any court or by any governmental agency with respect to the
Exchange Offer which, in the Company's judgment, would reasonably be expected to
impair its ability to proceed with the Exchange Offer and (iii) any such other
conditions as shall be agreed upon by the Company and the Initial Purchasers.

       (b)     In the event that (i) the Company and the Guarantors determine
that the Exchange Offer Registration provided for in Section 2(a) above is not
available or may not be completed as soon as practicable after the last Exchange
Date because it would violate any applicable law or applicable interpretations
of the Staff, (ii) the Exchange Offer is not for any other reason completed by
March 28, 2003, or (iii) upon the receipt of a written request (a "Shelf
Request") from any Initial Purchaser that it holds Registrable Securities that
are ineligible to be exchanged in the Exchange Offer, then the Company and the
Guarantors shall use their reasonable best efforts to cause to be filed as soon
as practicable after such determination, date or request, as the case may be, a
Shelf Registration Statement providing for the sale of all the Registrable
Securities by the Holders thereof and to have such Shelf Registration Statement
declared effective by the SEC. In the event the Initial Purchasers hold an
unsold allotment of the Securities on the 180th day after the date of this
Agreement, J.P. Morgan Securities Inc. or the relevant Initial Purchaser shall
notify the Company of such unsold allotment.

       In the event that the Company and the Guarantors are required to file a
Shelf Registration Statement pursuant to clause (iii) of the preceding sentence,
the Company and the Guarantors shall use their reasonable best efforts to file
and have declared effective by the SEC both an Exchange Offer Registration
Statement pursuant to Section 2(a) with respect to all Registrable Securities
and a Shelf Registration Statement (which may be a combined Registration
Statement with the Exchange Offer Registration Statement) with respect to offers
and sales of Registrable Securities held by the Initial Purchasers after
completion of the Exchange Offer.

       The Company and the Guarantors agree to use their reasonable best efforts
to keep the Shelf Registration Statement continuously effective until the
expiration of the earlier of (i) the period referred to in Rule 144(k) (or any
similar rule then in force but not Rule 144A) under the Securities Act with
respect to the Registrable Securities or (ii) such shorter period that will

                                                                               7

terminate when all the Registrable Securities covered by the Shelf Registration
Statement have been sold pursuant to the Shelf Registration Statement (in any
such case, the "Shelf Effectiveness Period"). The Company and the Guarantors
further agree to supplement or amend the Shelf Registration Statement and the
related Prospectus if required by the rules, regulations or instructions
applicable to the registration form used by the Company for such Shelf
Registration Statement or by the Securities Act or by any other rules and
regulations thereunder for shelf registration or if reasonably requested by a
Holder of Registrable Securities with respect to information relating to such
Holder, and to use their reasonable best efforts to cause any such amendment to
become effective and such Shelf Registration Statement and Prospectus to become
usable as soon as thereafter practicable. The Company and the Guarantors agree
to furnish to the Holders of Registrable Securities copies of any such
supplement or amendment promptly after its being used or filed with the SEC.

       (c)     The Company and the Guarantors shall pay all Registration
Expenses in connection with the registration pursuant to Section 2(a) and
Section 2(b) hereof. Each Holder shall pay all underwriting or broker-dealer
discounts and commissions and transfer taxes, if any, relating to the sale or
disposition of such Holder's Registrable Securities pursuant to the Shelf
Registration Statement and transfer taxes, if any, relating to the sale or
disposition of such Holder's Registrable Securities pursuant to the Exchange
Offer Registration Statement if the Holder instructs the Company to register the
Exchange Securities in the name of a person other than such Holder.

       (d)     An Exchange Offer Registration Statement pursuant to Section 2(a)
hereof or a Shelf Registration Statement pursuant to Section 2(b) hereof will
not be deemed to have become effective unless it has been declared effective by
the SEC.

       In the event that either the Exchange Offer is not completed or the Shelf
Registration Statement, if required pursuant to Section 2(b)(i) or Section
2(b)(ii) hereof, is not declared effective on or prior to March 28, 2003, the
interest rate on the Registrable Securities will be increased by 1.00% per annum
payable commencing from March 29, 2003 to and until the date the Exchange Offer
is completed or the Shelf Registration Statement, if required hereby, is
declared effective by the SEC or the Securities become freely tradable under the
Securities Act. In the event the Company receives a Shelf Request pursuant to
Section 2(b)(iii), and the Shelf Registration Statement required to be filed
thereby is not declared effective by the later of (x) February 26, 2003 or (y)
90 days after the delivery of such Shelf Request (such later date being
hereinafter referred to as the "Shelf Additional Interest Date"), then interest
rate on the Registrable Securities will be increased by 1.00% per annum payable
commencing from one day after the Shelf Additional Interest Date until the Shelf
Registration Statement is declared effective.

       Notwithstanding the foregoing, the Company and the Guarantors may,
pending the announcement of a potential acquisition, divestiture of assets or
other material corporate transaction, issue a notice that the Shelf Registration
Statement is no longer effective or the Prospectus contained therein is no
longer usable for offers and sales of Registrable Securities and may issue any
notice suspending use of the Shelf Registration Statement or the Prospectus
contained therein and in the event that the aggregate number of days in any
consecutive 360-day period for which all such notices are issued and effective
exceed 45 days in the aggregate, then

<Page>

                                                                               8

the interest rate on the Registrable Securities will be increased by 1.00% per
annum commencing on the 46th day in such 12-month period. The Company and the
Guarantors may give any such notice only twice during any 365-day period and any
such suspensions shall not exceed 30 days for each suspension and there shall
not be more than two suspensions in effect during any 365-day period. The
provisions of the foregoing sentence shall also be applicable to the Exchange
Offer Registration Statement during the Applicable Period, PROVIDED that the
Applicable Period shall be extended for the number of days that the use of the
Exchange Offer Registration Statement is suspended. If the Shelf Registration
Statement has been declared effective and thereafter either ceases to be
effective or the Prospectus contained therein ceases to be usable at any time
during the Shelf Effectiveness Period, and such failure to remain effective or
usable exists for more than 45 days (whether or not consecutive) in any 12-month
period, then the interest rate on the Registrable Securities will be increased
by 1.00% per annum commencing on the 46th day in such 12-month period and ending
on such date that the Shelf Registration Statement has again been declared
effective or the Prospectus again becomes usable.

       Notwithstanding anything to the contrary in this Section 2(d), neither
the Company nor any of the Guarantors shall be required to pay an increased
interest rate on the Registrable Securities to a Holder of Registrable
Securities during the period such Holder failed to comply with its obligations
to make the representations set forth in the third paragraph of Section 2(a) in
connection with any Exchange Offer or, in the case of a Shelf Registration
Statement failed to provide the information required to be provided by it, if
any, pursuant to Section 3(b), and the obligations to pay the increased rate of
interest shall resume upon the curing of such Holder's default.

       (e)     Without limiting the remedies available to the Initial Purchasers
and the Holders, the Company and the Guarantors acknowledge that any failure by
the Company or the Guarantors to comply with their obligations under Section
2(a) and Section 2(b) hereof may result in material irreparable injury to the
Initial Purchasers or the Holders for which there is no adequate remedy at law,
that it will not be possible to measure damages for such injuries precisely and
that, in the event of any such failure, the Initial Purchasers or any Holder may
obtain such relief as may be required to specifically enforce the Company's and
the Guarantors' obligations under Section 2(a) and Section 2(b) hereof.
Notwithstanding anything to the contrary in this Section 2(e), any Holder that
failed to comply with its obligations to make the representations set forth in
the third paragraph of Section 2(a) in connection with any Exchange Offer or, in
the case of a Shelf Registration Statement failed to provide the information
requested to be provided by it, if any, pursuant to Section 3(b), shall not be
entitled to the relief described in this Section 2(e) unless such failure is
cured or the Company and the Guarantors' failure to comply was not caused by
such Holder's default.

       3.      REGISTRATION PROCEDURES. (a) In connection with their obligations
pursuant to Section 2(a) and Section 2(b) hereof, the Company and the Guarantors
shall:

       (i)     prepare and file with the SEC a Registration Statement on the
appropriate form under the Securities Act, which form (x) shall be selected by
the Company and the Guarantors, (y) shall, in the case of a Shelf Registration,
be available for the sale of the Registrable Securities by the selling Holders
thereof in accordance with Section 2(b) and (z) shall comply as to form in all
material respects with the requirements of the applicable form and include all
financial

                                                                               9

statements required by the SEC to be filed therewith; and use their reasonable
best efforts to cause such Registration Statement to become effective and remain
effective for the applicable period in accordance with Section 2 hereof;

       (ii)    prepare and file with the SEC such amendments and post-effective
amendments to each Registration Statement as may be necessary to keep such
Registration Statement effective for the applicable period in accordance with
Section 2 hereof and cause each Prospectus to be supplemented by any required
prospectus supplement and, as so supplemented, to be filed pursuant to Rule 424
under the Securities Act; and keep each Prospectus current during the period
described in Section 4(3) of and Rule 174 under the Securities Act that is
applicable to transactions by brokers or dealers with respect to the Registrable
Securities or Exchange Securities;

       (iii)   in the case of a Shelf Registration, furnish to each Holder of
Registrable Securities included within the coverage of the Shelf Registration
Statement, to counsel for the Initial Purchasers, to counsel for such Holders
and to each Underwriter of an Underwritten Offering of Registrable Securities,
if any, without charge, as many copies of each Prospectus, including each
preliminary Prospectus, and any amendment or supplement thereto, in order to
facilitate the sale or other disposition of the Registrable Securities
thereunder; and the Company and the Guarantors consent to the use of such
Prospectus and any amendment or supplement thereto in accordance with applicable
law by each of the selling Holders of Registrable Securities and any such
Underwriters in connection with the offering and sale of the Registrable
Securities covered by and in the manner described in such Prospectus or any
amendment or supplement thereto in accordance with applicable law;

       (iv)    use their reasonable best efforts to register or qualify the
Registrable Securities under all applicable state securities or blue sky laws of
such jurisdictions as any Holder of Registrable Securities covered by a
Registration Statement shall reasonably request in writing by the time the
applicable Registration Statement is declared effective by the SEC; cooperate
with the Holders in connection with any filings required to be made with the
National Association of Securities Dealers, Inc.; and do any and all other acts
and things that may be reasonably necessary or advisable to enable each Holder
to complete the disposition in each such jurisdiction of the Registrable
Securities owned by such Holder; PROVIDED that neither the Company nor any
Guarantor shall be required to (1) qualify as a foreign corporation or other
entity or as a dealer in securities in any such jurisdiction where it would not
otherwise be required to so qualify, (2) file any general consent or subject
itself to service of process in any such jurisdiction or (3) subject itself to
taxation in any such jurisdiction if it is not so subject;

       (v)     in the case of a Shelf Registration, notify each Holder of
Registrable Securities included within the coverage of the Shelf Registration
Statement, counsel for such Holders and counsel for the Initial Purchasers
promptly and, if requested by any such Holder or counsel, confirm such advice in
writing (1) when a Registration Statement has become effective and when any
post-effective amendment thereto has been filed and becomes effective, (2) of
any request by the SEC or any state securities authority for amendments and
supplements to a Registration Statement and Prospectus or for additional
information after the Registration Statement has become effective, (3) of the
issuance by the SEC or any state securities authority of any stop order
suspending the effectiveness of a Registration Statement or the initiation of
any

<Page>

                                                                              10

proceedings for that purpose, (4) if, between the effective date of a
Registration Statement and the closing of any sale of Registrable Securities
covered thereby, the representations and warranties of the Company or any
Guarantor contained in any underwriting agreement, securities sales agreement or
other similar agreement, if any, relating to an offering of such Registrable
Securities cease to be true and correct in all material respects or if the
Company or any Guarantor receives any notification with respect to the
suspension of the qualification of the Registrable Securities for sale in any
jurisdiction or the initiation of any proceeding for such purpose, (5) of the
happening of any event during the period a Shelf Registration Statement is
effective that makes any statement made in such Registration Statement or the
related Prospectus untrue in any material respect or that requires the making of
any changes in such Registration Statement or Prospectus in order to make the
statements therein not misleading and (6) of any determination by the Company or
any Guarantor that a post-effective amendment to a Registration Statement would
be appropriate;

       (vi)    use their reasonable best efforts to obtain the withdrawal of any
order suspending the effectiveness of a Registration Statement at the earliest
possible moment and provide immediate notice to each Holder of the withdrawal of
any such order;

       (vii)   in the case of a Shelf Registration, furnish to each Holder of
Registrable Securities included within the coverage of the Shelf Registration
Statement, without charge, at least one conformed copy of each Registration
Statement and any post-effective amendment thereto (without any documents
incorporated therein by reference or exhibits thereto, unless requested in
writing);

       (viii)  in the case of a Shelf Registration, cooperate with the Holders
of Registrable Securities included within the coverage of such Shelf
Registration to facilitate the timely preparation and delivery of certificates
representing Registrable Securities to be sold and not bearing any restrictive
legends and enable such Registrable Securities to be issued in such
denominations and registered in such names (consistent with the provisions of
the Indenture) as the selling Holders may reasonably request in writing at least
one Business Day prior to the closing of any sale of Registrable Securities;

       (ix)    in the case of a Shelf Registration, upon the occurrence of any
event contemplated by Section 3(a)(v)(5) hereof, use their reasonable best
efforts to prepare and file with the SEC a supplement or post-effective
amendment to a Registration Statement or the related Prospectus or any document
incorporated therein by reference or file any other required document so that,
as thereafter delivered to purchasers of the Registrable Securities, such
Prospectus will not contain any untrue statement of a material fact or omit to
state a material fact necessary to make the statements therein, in the light of
the circumstances under which they were made, not misleading; and the Company
and the Guarantors shall notify the Holders of Registrable Securities to suspend
use of the Prospectus as promptly as practicable after the occurrence of such an
event, and such Holders hereby agree (a) to suspend use of the Prospectus until
the Company and the Guarantors have amended or supplemented the Prospectus to
correct such misstatement or omission and (b) to maintain the information
contained in such notice and the existence of such notice confidential unless
and until the information is made publicly available by the Company or the
Guarantors or otherwise (other than by action of the Holders) becomes publicly
available;

                                                                              11

       (x)     a reasonable time prior to the filing of any Registration
Statement, any Prospectus, any amendment to a Registration Statement or
amendment or supplement to a Prospectus or of any document that is to be
incorporated by reference into a Registration Statement or a Prospectus after
initial filing of a Registration Statement, provide copies of such document to
the Initial Purchasers and their counsel (and, in the case of a Shelf
Registration Statement, to the Holders of Registrable Securities included within
the coverage of such Shelf Registration and their counsel) and make such of the
representatives of the Company and the Guarantors as shall be reasonably
requested by the Initial Purchasers or their counsel (and, in the case of a
Shelf Registration Statement, the Holders of Registrable Securities included
within the coverage of such Shelf Registration or their counsel) available for
discussion of such document; and the Company and the Guarantors shall not, at
any time after initial filing of a Registration Statement, file any Prospectus,
any amendment of or supplement to a Registration Statement or a Prospectus, or
any document that is to be incorporated by reference into a Registration
Statement or a Prospectus, of which the Initial Purchasers and their counsel
(and, in the case of a Shelf Registration Statement, the Holders of Registrable
Securities included within the coverage of such Shelf Registration and their
counsel) shall not have previously been advised and furnished a copy or to which
the Initial Purchasers or their counsel (and, in the case of a Shelf
Registration Statement, the Holders of Registrable Securities included within
the coverage of such Shelf Registration or their counsel) shall reasonably
object within a reasonable period of time after receipt of such documents and in
each case after having been afforded the opportunity to diligence such matters
with the Company and the Guarantors;

       (xi)    obtain a CUSIP number for all Exchange Securities not later than
the effective date of a Registration Statement;

       (xii)   cause the Indenture to be qualified under the Trust Indenture Act
in connection with the registration of the Exchange Securities or Registrable
Securities, as the case may be; cooperate with the Trustee and the Holders to
effect such changes to the Indenture as may be required for the Indenture to be
so qualified in accordance with the terms of the Trust Indenture Act; and
execute, and use their reasonable best efforts to cause the Trustee to execute,
all documents as may be required to effect such changes and all other forms and
documents required to be filed with the SEC to enable the Indenture to be so
qualified in a timely manner;

       (xiii)  in the case of a Shelf Registration, make available for
inspection by a representative of the Holders of the Registrable Securities
included within the coverage of such Shelf Registration (an "Inspector"), any
Underwriter participating in any disposition pursuant to such Shelf Registration
Statement, and attorneys and accountants designated by the Holders and any such
Underwriter, at reasonable times and in a reasonable manner, all pertinent
financial and other records, documents and properties of the Company and the
Guarantors, and cause the respective officers, directors and employees of the
Company and the Guarantors to supply all information reasonably requested by any
such Inspector, Underwriter, attorney or accountant in connection with the
performance of their "due diligence" investigation or marketing efforts with
respect to a Shelf Registration Statement; PROVIDED that if any such information
is identified by the Company or any Guarantor as being confidential or
proprietary and the disclosure of such information is not necessary so that the
Prospectus does not contain an untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading, each Person receiving such information shall
take such actions

<Page>

                                                                              12

as are reasonably necessary to protect the confidentiality of such information
to the extent such action is otherwise not inconsistent with, an impairment of
or in derogation of the rights and interests of any Inspector, Holder or
Underwriter;

       (xiv)   in the case of a Shelf Registration, use their reasonable best
efforts to cause all Registrable Securities included within the coverage of such
Shelf Registration to be listed on any securities exchange or any automated
quotation system on which similar securities issued or guaranteed by the Company
or any Guarantor are then listed if requested by the Majority Holders, to the
extent such Registrable Securities satisfy applicable listing requirements;

       (xv)    if reasonably requested by any Holder of Registrable Securities
covered by a Registration Statement, promptly incorporate in a Prospectus
supplement or post-effective amendment such information with respect to such
Holder as such Holder reasonably requests to be included therein so that such
Prospectus does not contain an untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading with respect to the information required to be
stated therein with respect to such Holder and make all required filings of such
Prospectus supplement or such post-effective amendment as soon as the Company
has received notification of the matters to be incorporated in such filing; and

       (xvi)   in the case of a Shelf Registration, enter into such customary
agreements and take all such other actions in connection therewith (including
those requested by the Holders of a majority in principal amount of the
Registrable Securities included within the coverage of such Shelf Registration)
in order to expedite or facilitate the disposition of such Registrable
Securities including, but not limited to, an Underwritten Offering and in such
connection, (i) to the extent possible, make such representations and warranties
to the Holders and any Underwriters of such Registrable Securities with respect
to the business of the Company and its subsidiaries, the Registration Statement,
Prospectus and documents incorporated by reference or deemed incorporated by
reference, if any, in each case, in form, substance and scope as are customarily
made by issuers to underwriters in underwritten offerings and confirm the same
if and when requested, (ii) in the case of an Underwritten Offering obtain
opinions of counsel to the Company and the Guarantors (which counsel and
opinions, in form, scope and substance, shall be reasonably satisfactory to the
Holders and such Underwriters and their respective counsel) addressed to each
selling Holder and Underwriter of Registrable Securities included within the
coverage of such Shelf Registration, covering the matters customarily covered in
opinions requested in underwritten offerings, (iii) in the case of an
Underwritten Offering obtain "comfort" letters from the independent certified
public accountants of the Company and the Guarantors (and, if necessary, any
other certified public accountant of any subsidiary of the Company or any
Guarantor, or of any business acquired by the Company or any Guarantor for which
financial statements and financial data are or are required to be included in
the Registration Statement) addressed to each selling Holder and Underwriter of
Registrable Securities included within the coverage of such Shelf Registration,
such letters to be in customary form and covering matters of the type
customarily covered in "comfort" letters in connection with underwritten
offerings and (iv) deliver such documents and certificates as may be reasonably
requested by the Holders of a majority in principal amount of the Registrable
Securities included within the coverage of such Shelf Registration being sold or
the Underwriters, and which are customarily delivered in underwritten offerings,
to evidence the

<Page>

                                                                              13

continued validity of the representations and warranties of the Company and the
Guarantors made pursuant to clause (i) above and in the case of an Underwritten
Offering to evidence compliance with any customary conditions contained in an
underwriting agreement.

       (b) In the case of a Shelf Registration Statement, upon request of the
Company and the Guarantors, each Holder of Registrable Securities included
within the coverage of such Shelf Registration shall be required to furnish to
the Company in writing after receipt of request therefor (within a reasonable
period of time of such request) the information with respect to such Holder
specified in Items 507 and 508 (as applicable) of Regulation S-K under the
Securities Act, and such other information regarding such Holder and the
proposed disposition by such Holder of such Registrable Securities as the
Company and the Guarantors may from time to time reasonably request in writing,
and the Company may exclude from such Shelf Registration Statement the
Registrable Securities of any Holder that fails to furnish such information
within a reasonable period of time of such request until the delivery of such
written information. Each Holder of Registrable Securities included within the
coverage of a Shelf Registration Statement, by its participation in the Shelf
Statement, shall be deemed to agree to furnish the Company and the Guarantors
all information concerning such Holder required to be described in order to make
the information previously furnished by such Holder to the Company and the
Guarantors not materially misleading.

       (c) In the case of a Shelf Registration Statement, each Holder of
Registrable Securities included within the coverage of such Shelf Registration
agrees that, upon receipt of any notice from the Company and the Guarantors of
the happening of any event of the kind described in Section 3(a)(v)(3) or
3(a)(v)(5) hereof, such Holder will forthwith discontinue disposition of
Registrable Securities pursuant to a Shelf Registration Statement until such
Holder's receipt of the copies of the supplemented or amended Prospectus
contemplated by Section 3(a)(ix) hereof and, if so directed by the Company and
the Guarantors, such Holder will deliver to the Company and the Guarantors all
copies in its possession, other than permanent file copies then in such Holder's
possession, of the Prospectus covering such Registrable Securities that is
current at the time of receipt of such notice.

       (d) If the Company and the Guarantors shall give any such notice to
suspend the disposition of Registrable Securities pursuant to a Registration
Statement, the Company and the Guarantors shall extend the period during which
the Registration Statement shall be maintained effective pursuant to this
Agreement by the number of days during the period from and including the date of
the giving of such notice to and including the date when the Holders shall have
received copies of the supplemented or amended Prospectus necessary to resume
such dispositions. The Company and the Guarantors may give any such notice only
twice during any 365-day period and any such suspensions shall not exceed 30
days for each suspension and there shall not be more than two suspensions in
effect during any 365-day period.

       (e) The Holders of Registrable Securities included within the coverage of
a Shelf Registration Statement who desire to do so may sell such Registrable
Securities in an Underwritten Offering. In any such Underwritten Offering, the
investment banker or investment bankers and manager or managers (the
"Underwriters") that will administer the offering will be selected by the
Majority Holders of the Registrable Securities included in such offering,
subject to the consent of the Company and the Guarantors (which consent shall
not be unreasonably

<Page>

                                                                              14

withheld or delayed), and such Holders shall be responsible for all underwriting
commissions and discounts in connection therewith.

       4.      PARTICIPATION OF BROKER-DEALERS IN EXCHANGE OFFER. (a) The Staff
has taken the position that any broker-dealer that receives Exchange Securities
for its own account in the Exchange Offer in exchange for Securities that were
acquired by such broker-dealer as a result of market-making or other trading
activities (a "Participating Broker-Dealer") may be deemed to be an
"underwriter" within the meaning of the Securities Act and must deliver a
prospectus meeting the requirements of the Securities Act in connection with any
resale of such Exchange Securities.

       The Company and the Guarantors understand that it is the Staff's position
that if the Prospectus contained in the Exchange Offer Registration Statement
includes a plan of distribution containing a statement to the above effect and
the means by which Participating Broker-Dealers may resell the Exchange
Securities, without naming the Participating Broker-Dealers or specifying the
amount of Exchange Securities owned by them, such Prospectus may be delivered by
Participating Broker-Dealers to satisfy their prospectus delivery obligation
under the Securities Act in connection with resales of Exchange Securities for
their own accounts, so long as the Prospectus otherwise meets the requirements
of the Securities Act.

       (b)     In light of the above, and notwithstanding the other provisions
of this Agreement, the Company and the Guarantors agree to amend or supplement
the Prospectus contained in the Exchange Offer Registration Statement, as would
otherwise be contemplated by Section 3(a)(ix), for a period of up to 180 days
after the last Exchange Date (as such period may be extended pursuant to Section
3(d) of this Agreement), if requested in writing by the Initial Purchasers or by
one or more Participating Broker-Dealers, in order to expedite or facilitate the
disposition of any Exchange Securities by Participating Broker-Dealers
consistent with the positions of the Staff recited in Section 4(a) above. The
Company and the Guarantors further agree that Participating Broker-Dealers shall
be authorized to deliver such Prospectus during such period in connection with
the resales contemplated by this Section 4.

       (c)     The Initial Purchasers shall have no liability to the Company,
any Guarantor or any Holder with respect to any request that they may make
pursuant to Section 4(b) above.

       5.      MARKET-MAKING. (a) For so long as any of the Securities or
Exchange Securities are outstanding and JPMorgan (in such capacity, the
"Market-Maker") or any of its affiliates (as defined in the rules and
regulations of the SEC) owns any equity securities of the Company, the
Guarantors or any of their affiliates and proposes to make a market in the
Securities or Exchange Securities as part of its business in the ordinary
course, the following provisions shall apply for the sole benefit of the
Market-Maker:

               (i)     The Company and the Guarantors shall (A) on the earlier
       of the date that the Exchange Offer Registration Statement or the Shelf
       Registration Statement is filed with the SEC, file a registration
       statement (the "Market-Making Registration Statement") (which may be the
       Exchange Offer Registration Statement or the Shelf Registration Statement
       if permitted by the rules and regulations of the SEC) and use their best
       efforts to cause such Market-Making Registration Statement to be declared
       effective by the SEC on or prior to the consummation of the Exchange
       Offer or the effective date of the Shelf

<Page>

                                                                              15

       Registration Statement, as applicable; (B) periodically amend such
       Market-Making Registration Statement so that the information contained
       therein complies with the requirements of Section 10(a) under the
       Securities Act; (C) amend the Market-Making Registration Statement or
       supplement the related Prospectus when necessary to reflect any material
       changes in the information provided therein; and (D) amend the
       Market-Making Registration Statement when required to do so in order to
       comply with Section 10(a)(3) of the Securities Act; PROVIDED, HOWEVER,
       that (1) prior to filing the Market-Making Registration Statement, any
       amendment thereto or any supplement to the related Prospectus, the
       Company will furnish to the Market-Maker copies of all such documents
       proposed to be filed, which documents will be subject to the review of
       the Market-Maker and its counsel (which may be in-house counsel), (2) the
       Company and the Guarantors will not file the Market-Making Registration
       Statement, any amendment thereto or any supplement to the related
       Prospectus to which the Market-Maker and its counsel shall reasonably
       object unless the Company is advised by counsel that such Market-Making
       Registration Statement, amendment or supplement in the form presented to
       the Market-Maker is required to be filed and (3) the Company will provide
       the Market-Maker and its counsel with copies of the Market-Making
       Registration Statement and each amendment and supplement filed.

               (ii)    The Company shall notify the Market-Maker and, if
       requested by the Market-Maker, confirm such advice in writing, (A) when
       any post-effective amendment to the Market-Making Registration Statement
       or any amendment or supplement to the related Prospectus has been filed,
       and, with respect to any post-effective amendment, when the same has
       become effective; (B) of any request by the SEC for any post-effective
       amendment to the Market-Making Registration Statement, any supplement or
       amendment to the related Prospectus or for additional information; (C)
       the issuance by the SEC of any stop order suspending the effectiveness of
       the Market-Making Registration Statement or the initiation of any
       proceedings for that purpose; (D) of the receipt by the Company of any
       notification with respect to the suspension of the qualification of the
       Securities or Exchange Securities for sale in any jurisdiction or the
       initiation or threatening of any proceedings for such purpose; (E) of the
       happening of any event that makes any statement made in the Market-Making
       Registration Statement, the related Prospectus or any amendment or
       supplement thereto untrue or that requires the making of any changes in
       the Market-Making Registration Statement, such Prospectus or any
       amendment or supplement thereto, in order to make the statements therein
       not misleading; and (F) of any advice from a nationally recognized
       statistical rating organization that such organization has placed the
       Company under surveillance or review with negative implications or has
       determined to downgrade the rating of the Securities or Exchange
       Securities or any other debt obligation of the Company whether or not
       such downgrade shall have been publicly announced.

               (iii)   If any event contemplated by Section 5(a)(ii)(B) through
       (E) occurs during the period for which the Company and the Guarantors are
       required to maintain an effective Market-Making Registration Statement,
       the Company and the Guarantors shall promptly prepare and file with the
       SEC a post-effective amendment to the Market-Making Registration
       Statement or a supplement to the related Prospectus or file any other
       required document so that the Prospectus will not include an untrue
       statement of a

                                                                              16

       material fact or omit to state a material fact necessary in order to make
       the statements therein, in the light of the circumstances under which
       they were made, not misleading.

               (iv)    In the event of the issuance of any stop order suspending
       the effectiveness of the Market-Making Registration Statement or of any
       order suspending the qualification of the Securities or Exchange
       Securities for sale in any jurisdiction, the Company and the Guarantors
       shall use promptly their reasonable best efforts to obtain its
       withdrawal.

               (v)     The Company shall furnish to the Market-Maker, without
       charge, (i) at least one conformed copy of the Market-Making Registration
       Statement and any post-effective amendment thereto; and (ii) as many
       copies of the related Prospectus and any amendment or supplement thereto
       as the Market-Maker may reasonably request.

               (vi)    The Company and the Guarantors shall consent to the use
       of the Prospectus contained in the Market-Making Registration Statement
       or any amendment or supplement thereto by the Market-Maker in connection
       its market-making activities.

               (vii)   Notwithstanding the foregoing provisions of this Section
       5, the Company and the Guarantors may for valid business reasons,
       including, without limitation, a potential acquisition, divestiture of
       assets or other material corporate transaction, issue a notice that the
       Market-Making Registration Statement is no longer effective or the
       Prospectus included therein is no longer usable for offers and sales of
       Securities or Exchange Securities and may issue any notice suspending use
       of the Market-Making Registration Statement required under applicable
       securities laws to be issued; PROVIDED that the use of the Market-Making
       Registration Statement shall not be suspended for more than 60 days in
       the aggregate in any consecutive 12 month period. The Market-Maker agrees
       that upon receipt of any notice from the Company pursuant to this Section
       5(a)(vii), it will discontinue use of the Market-Making Registration
       Statement until receipt of copies of the supplemented or amended
       Prospectus relating thereto or until advised in writing by the Company
       that the use of the Market-Making Registration Statement may be resumed.

       (b)     In connection with the Market-Making Registration Statement, the
Company shall (i) make reasonably available for inspection by a representative
of, and counsel acting for, the Market-Maker all relevant financial and other
records, pertinent corporate documents and properties of the Company and its
subsidiaries and (ii) use its reasonable best efforts to have its officers,

reasonably requested by such representative or counsel or the Market-Maker.

       (c)     Prior to the effective date of the Market-Making Registration
Statement, the Company and the Guarantors will use their reasonable best efforts
to register or qualify such Securities or Exchange Securities for offer and sale
under the securities or blue sky laws of such jurisdictions as the Market-Maker
reasonably requests in writing and do any and all other acts or things necessary
or advisable to enable the offer and sale in such jurisdictions of the
Securities or Exchange Securities covered by the Market-Making Registration
Statement; PROVIDED that neither the Company nor any Guarantor shall be required
to (i) qualify as a foreign corporation

<Page>

                                                                              17

or other entity or as a dealer in securities in any jurisdiction where it would
not otherwise be required to so qualify, (ii) file any general consent to
subject itself to service of process in any such jurisdiction or (iii) subject
itself to taxation in any such jurisdiction if it is not subject.

       (d)     The Company represents that the Market-Making Registration
Statement, any post-effective amendments thereto, any amendments or supplements
to the related Prospectus and any documents filed by them under the Exchange Act
will, when they become effective or are filed with the SEC, as the case may be,
conform in all respects to the requirements of the Securities Act and the
Exchange Act and the rules and regulations of the SEC thereunder and will not,
as of the effective date of such Market-Making Registration Statement or
post-effective amendments and as of the filing date of amendments or supplements
to such Prospectus or filings under the Exchange Act, contain an untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein in light of the
circumstances under which they were made not misleading; PROVIDED that no
representation or warranty is made as to information contained in or omitted
from the Market-Making Registration Statement or the related Prospectus in
reliance upon and in conformity with written information furnished to the
Company by the Market-Maker specifically for inclusion therein, which
information the parties hereto agree will be limited to the statements
concerning the Market-Making activities of the Market-Maker to be set forth on
the cover page and in the "Plan of Distribution" section of the Prospectus (the
"Market-Maker's Information").

       (e)     At the time of effectiveness of the Market-Making Registration
Statement (unless it is the same as the time of effectiveness of the Exchange
Offer Registration Statement) and concurrently with each time the Market-Making
Registration Statement or the related Prospectus shall be amended or such
Prospectus shall be supplemented, the Company shall (if requested in writing by
the Market-Maker) furnish the Market-Maker and its counsel with a certificate of
its Chairman of the Board of Directors or Chief Financial Officer to the effect
that:

               (i)     the Market-Making Registration Statement has been
       declared effective;

               (ii)    in the case of an amendment or supplement, such amendment
       has become effective under the Securities Act as of the date and time
       specified in such certificate, if applicable; if required, such amendment
       or supplement to the Prospectus was filed with the SEC pursuant to the
       subparagraph of Rule 424(b) under the Securities Act specified in such
       certificate on the date specified therein;

               (iii)   to the knowledge of such officers, no stop order
       suspending the effectiveness of the Market-Making Registration Statement
       has been issued and no proceeding for that purpose is pending or
       threatened by the SEC; and

               (iv)    such officers have carefully examined the Market-Making
       Registration Statement and the Prospectus (and, in the case of an
       amendment or supplement, such amendment or supplement) and as of the date
       of such Market-Making Registration Statement, amendment or supplement, as
       applicable, the Market-Making Registration Statement and the Prospectus,
       as amended or supplemented, if applicable, did not include any untrue
       statement of a material fact and did not omit to state a material fact
       required to be stated therein or necessary to make the statements therein
       not misleading.

                                                                              18

       (f)     At the time of effectiveness of the Market-Making Registration
Statement (unless it is the same as the time of effectiveness of the Exchange
Offer Registration Statement) and concurrently with each time the Market-Making
Registration Statement or the related Prospectus shall be amended or such
Prospectus shall be supplemented, the Company shall (if requested in writing by
the Market-Maker) furnish the Market-Maker and its counsel with the written
opinion of counsel for the Company satisfactory to the Market-Maker to the
effect that:

               (i)     the Market-Making Registration Statement has been
       declared effective;

               (ii)    in the case of an amendment or supplement, such amendment
       has become effective under the Securities Act as of the date and time
       specified in such opinion, if applicable; if required, such amendment or
       supplement to the Prospectus was filed with the SEC pursuant to the
       subparagraph of Rule 424(b) under the Securities Act specified in such
       opinion on the date specified therein;

               (iii)   to the knowledge of such counsel, no stop order
       suspending the effectiveness of the Market-Making Registration Statement
       has been issued and no proceeding for that purpose is pending or
       threatened by the SEC; and

               (iv)    such counsel has reviewed the Market-Making Registration
       Statement and the Prospectus (and, in the case of an amendment or
       supplement, such amendment or supplement) and participated with officers
       of the Company and independent public accountants for the Company in the
       preparation of such Market-Making Registration Statement and Prospectus
       (and, in the case of an amendment or supplement, such amendment or
       supplement) and has no reason to believe that (except for the financial
       statements and other financial and statistical data contained therein as
       to which no belief is required) as of the date of such Market-Making
       Registration Statement, amendment or supplement, as applicable, the
       Market-Making Registration Statement and the Prospectus, as amended or
       supplemented, if applicable, contained any untrue statement of a material
       fact or omitted to state a material fact required to be stated therein or
       necessary to make the statements therein not misleading.

       (g)     At the time of effectiveness of the Market-Making Registration
Statement (unless it is the same as the time of effectiveness of the Exchange
Offer Registration Statement) and concurrently with each time the Market-Making
Registration Statement or the related Prospectus shall be amended or such
Prospectus shall be supplemented to include audited annual financial
information, the Company shall (if requested in writing by the Market-Maker)
furnish the Market-Maker and its counsel with a letter of PricewaterhouseCoopers
LLP (or other independent public accountants for the Company or the Guarantors
of nationally recognized standing) in form satisfactory to the Market-Maker,
addressed to the Market-Maker and dated the date of delivery of such letter, (i)
confirming that they are independent public accountants within the meaning of
the Securities Act and are in compliance with the applicable requirements
relating to the qualification of accountants under Rule 2-01 of Regulation S-X
of the SEC and, (ii) in all other respects, substantially in the form of the
letter delivered to the Initial Purchasers pursuant to Section 5(f) of the
Purchase Agreement, with, in the case of an amendment or supplement to include
audited financial information, such changes as may be necessary to reflect the
amended or supplemented financial information.

       (h)     The Company and the Guarantors, on the one hand, and the
Market-Maker, on the other hand, hereby agree to indemnify each other, and, if
applicable, contribute to the other, in accordance with Section 6 of this
Agreement.

       (i)     The Company will comply with the provisions of this Section 5 at
its own expense and will reimburse the Market-Maker for its expenses associated
with this Section 5 (including reasonable fees of counsel, other than in-house
counsel of the Market-Maker).

       (j)     The agreements contained in this Section 5 and the
representations, warranties and agreements contained in this Agreement shall
survive all offers and sales of the Securities and Exchange Securities and shall
remain in full force and effect, regardless of any termination or cancellation
of this Agreement or any investigation made by or on behalf of any indemnified
party.

       (k)     For purposes of this Section 5, any reference to the terms
"amend", "amendment" or "supplement" with respect to the Market-Making
Registration Statement or the Prospectus contained therein shall be deemed to
refer to and include the filing under the Exchange Act of any document deemed to
be incorporated therein by reference.

       6.      INDEMNIFICATION AND CONTRIBUTION. (a) The Company and each
Guarantor, jointly and severally, agree to indemnify and hold harmless (i) each
Initial Purchaser, the Market-Maker and each Holder, their respective
affiliates, directors and officers and each Person, if any, who controls any
Initial Purchaser, the Market-Maker or any Holder within the meaning of Section
15 of the Securities Act or Section 20 of the Exchange Act, from and against any
and all losses, claims, damages and liabilities (including, without limitation,
legal fees and other expenses reasonably incurred in connection with any suit,
action or proceeding or any claim asserted, as such fees and expenses are
incurred), joint or several, that arise out of, or are based upon, any untrue
statement or alleged untrue statement of a material fact contained in any
Registration Statement or Market-Making Registration Statement or any Prospectus
or any omission or alleged omission to state therein a material fact required to
be stated therein or necessary in order to make the statements therein, in the
light of the circumstances under which they were made, not misleading, except
insofar as such losses, claims, damages or liabilities arise out of, or are
based upon, (x) any untrue statement or omission or alleged untrue statement or
omission made in reliance upon and in conformity with any information relating
to any Initial Purchaser, information relating to any Holder or the
Market-Maker's Information furnished to the Company in writing through JPMorgan,
the Market Maker or any selling Holder expressly for use therein and (y) any
untrue statement or omission or alleged untrue statement or omission that was
contained or made in any related preliminary Prospectus, if both (A) a copy of
the final Prospectus was not sent or given by such initial Purchaser,
Market-Maker or Holder to such Person asserting any such loss, claim, damage or
liability on or prior to the written confirmation of the sale of such Securities
or Exchange Securities to such Person and (B) the untrue statement in or
omission from the related preliminary Prospectus was corrected in the final
Prospectus and the Company complied with its agreements in Section 3(a)(ii),
3(a)(iii), 3(a)(vii), 3(a)(ix) or 5(a)(v), as applicable and (ii) the
Market-Maker from and against any and all losses, claims, damages and
liabilities (including, without limitation, legal fees and other expenses
incurred in connection with any suit, action or proceeding or any claim
asserted, as such fees and expenses are incurred), joint or several that arise
out of, or are based upon, any material breach by the

<Page>

                                                                              20

Company of its representations, warranties and agreements contained in Section
5. In connection with any Underwritten Offering permitted by Section 3, the
Company and the Guarantors, jointly and severally, will also indemnify the
Underwriters, if any, selling brokers, dealers and similar securities industry
professionals participating in the distribution, their respective affiliates and
each Person who controls such Persons (within the meaning of the Securities Act
and the Exchange Act) to the same extent as provided above with respect to the
indemnification of the Holders, if requested in connection with any Registration
Statement.

       (b)     Each Holder agrees, severally and not jointly, to indemnify and
hold harmless the Company, the Guarantors, the Initial Purchasers and the other
selling Holders, their respective affiliates, the directors of the Company and
the Guarantors, each officer of the Company and the Guarantors who signed the
Registration Statement and each Person, if any, who controls the Company, the
Guarantors, any Initial Purchaser and any other selling Holder within the
meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to
the same extent as the indemnity set forth in paragraph (a) above, but only with
respect to any losses, claims, damages or liabilities that arise out of, or are
based upon, any untrue statement or omission or alleged untrue statement or
omission made in reliance upon and in conformity with any information relating
to such Holder furnished to the Company in writing by such Holder expressly for
use in any Registration Statement or any Prospectus.

       (c)     The Market-Maker agrees to indemnify and hold harmless the
Company and the Guarantors, and their respective affiliates, the directors and
officers of the Company and the Guarantors who signed the Market-Marking
Registration Statement and each Person, if any, who controls the Company or the
Guarantors within the meaning of Section 15 of the Securities Act or Section 20
of the Exchange Act to the same extent as the indemnity set forth in paragraph
(a) above, but only with respect to any losses, claims, damages or liabilities
that arise out of, or are based upon, any untrue statement or omission or
alleged untrue statement or omission made in reliance upon and in conformity
with any Market-Maker's Information furnished to the Company in writing by the
Market-Maker expressly for use in any Market-Marking Registration Statement or
any Prospectus.

       (d)     If any suit, action, proceeding (including any governmental or
regulatory investigation), claim or demand shall be brought or asserted against
any Person in respect of which indemnification may be sought pursuant to
paragraph (a), (b) or (c) above, such Person (the "Indemnified Person") shall
promptly notify the Person against whom such indemnification may be sought (the
"Indemnifying Person") in writing; PROVIDED that the failure to notify the
Indemnifying Person shall not relieve it from any liability that it may have
under this Section 6 except to the extent that it has been materially prejudiced
(through the forfeiture of substantive rights or defenses) by such failure; and
PROVIDED, FURTHER, that the failure to notify the Indemnifying Person shall not
relieve it from any liability that it may have to an Indemnified Person
otherwise than under this Section 6. If any such proceeding shall be brought or
asserted against an Indemnified Person and it shall have notified the
Indemnifying Person thereof, the Indemnifying Person shall retain counsel
reasonably satisfactory to the Indemnified Person to represent the Indemnified
Person and any others entitled to indemnification pursuant to this Section 6
that the Indemnifying Person may designate in such proceeding and shall pay the
fees and expenses of such counsel related to such proceeding, as incurred upon
presentation of invoices. In any such proceeding, any Indemnified Person shall
have the right to retain its own

<Page>

                                                                              21

counsel, but the fees and expenses of such counsel shall be at the expense of
such Indemnified Person unless (i) the Indemnifying Person and the Indemnified
Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person
has failed within a reasonable time to retain counsel reasonably satisfactory to
the Indemnified Person; (iii) the Indemnified Person shall have reasonably
concluded that there may be legal defenses available to it that are different
from or in addition to those available to the Indemnifying Person; or (iv) the
named parties in any such proceeding (including any impleaded parties) include
both the Indemnifying Person and the Indemnified Person and representation of
both parties by the same counsel would be inappropriate due to actual or
potential differing interests between them. It is understood and agreed that the
Indemnifying Person shall not, in connection with any proceeding or related
proceeding in the same jurisdiction, be liable for the fees and expenses of more
than one separate firm (in addition to any local counsel) for all Indemnified
Persons, and that all such fees and expenses shall be reimbursed as they are
incurred upon presentation of invoices. Any such separate firm (x) for any
Initial Purchaser, its affiliates, directors and officers and any control
Persons of such Initial Purchaser or the Market-Maker shall be designated in
writing by JPMorgan, (y) for any Holder, its affiliates, directors and officers
and any control Persons of such Holder shall be designated in writing by the
Majority Holders and (z) in all other cases shall be designated in writing by
the Company. The Indemnifying Person shall not be liable for any settlement of
any proceeding effected without its written consent, but if settled with such
consent or if there be a final judgment for the plaintiff, the Indemnifying
Person agrees to indemnify each Indemnified Person from and against any loss or
liability by reason of such settlement or judgment. Notwithstanding the
foregoing sentence, if at any time an Indemnified Person shall have requested
that an Indemnifying Person reimburse the Indemnified Person for the reasonable
fees and expenses of counsel as contemplated by this paragraph, the Indemnifying
Person shall be liable for any settlement of any proceeding effected without its
written consent if (i) such settlement is entered into more than 45 days after
receipt by the Indemnifying Person of such request and (ii) the Indemnifying
Person shall not have reimbursed the Indemnified Person in accordance with such
request prior to the date of such settlement. No Indemnifying Person shall,
without the written consent of the Indemnified Person, effect any settlement of
any pending or threatened proceeding in respect of which any Indemnified Person
is or could have been a party and indemnification could have been sought
hereunder by such Indemnified Person, unless such settlement (A) includes an
unconditional release of such Indemnified Person, in form and substance
reasonably satisfactory to such Indemnified Person, from all liability on claims
that are the subject matter of such proceeding and (B) does not include any
statement as to or any admission of fault, culpability or a failure to act by or
on behalf of any Indemnified Person.

       (e)     If the indemnification provided for in paragraphs (a), (b) and
(c) above is unavailable to an Indemnified Person or insufficient in respect of
any losses, claims, damages or liabilities referred to therein, then each
Indemnifying Person under such paragraph, in lieu of indemnifying such
Indemnified Person thereunder, shall contribute to the amount paid or payable by
such Indemnified Person as a result of such losses, claims, damages or
liabilities (i) in such proportion as is appropriate to reflect the relative
benefits received by the Company and the Guarantors from the initial offering
and sale of the Securities and the Exchange Securities, on the one hand, and by
the Holders from receiving Securities or Exchange Securities registered under
the Securities Act, on the other hand, or (ii) if the allocation provided by
clause (i) is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause (i)
but also the relative fault of the Company and the Guarantors on

<Page>

                                                                              22

the one hand and the Holders or the Market-Maker on the other in connection with
the statements or omissions that resulted in such losses, claims, damages or
liabilities, as well as any other relevant equitable considerations. The
relative fault of the Company and the Guarantors on the one hand and the Holders
or the Market-Maker on the other shall be determined by reference to, among
other things, whether the untrue or alleged untrue statement of a material fact
or the omission or alleged omission to state a material fact relates to
information supplied by the Company and the Guarantors or by the Holders or
Market-Maker's Information, as applicable, and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission.

       (f)     The Company, the Guarantors, the Holders and the Marker-Maker
agree that it would not be just and equitable if contribution pursuant to this
Section 6 were determined by pro rata allocation (even if the Holders were
treated as one entity for such purpose) or by any other method of allocation
that does not take account of the equitable considerations referred to in
paragraph (e) above. The amount paid or payable by an Indemnified Person as a
result of the losses, claims, damages and liabilities referred to in paragraph
(e) above shall be deemed to include, subject to the limitations set forth
above, any legal or other expenses reasonably incurred by such Indemnified
Person in connection with any such action or claim. Notwithstanding the
provisions of this Section 6, in no event shall a Holder be required to
contribute any amount in excess of the amount by which the total price at which
the Securities or Exchange Securities sold by such Holder exceeds the amount of
any damages that such Holder has otherwise been required to pay by reason of
such untrue or alleged untrue statement or omission or alleged omission, nor
shall the Market-Maker be required to contribute any amount in excess of its
commission from the market-making transactions at issue. No Person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any Person who was not
guilty of such fraudulent misrepresentation.

       (g)     The remedies provided for in this Section 6 are not exclusive and
shall not limit any rights or remedies that may otherwise be available to any
Indemnified Person at law or in equity.

       (h)     The indemnity and contribution provisions contained in this
Section 6 shall remain operative and in full force and effect regardless of (i)
any termination of this Agreement, (ii) any investigation made by or on behalf
of the Initial Purchasers, the Market-Maker or any Holder, their respective
affiliates or any Person controlling any Initial Purchaser, the Market-Maker or
any Holder, or by or on behalf of the Company or the Guarantors, their
respective affiliates or the officers or directors of or any Person controlling
the Company or the Guarantors, (iii) acceptance of any of the Exchange
Securities, or (iv) any sale of Registrable Securities pursuant to a Shelf
Registration Statement or a Market-Making Registration Statement.

       7.      GENERAL.

                                                                              23

agreement and (ii) neither the Company nor any Guarantor has entered into, or on
or after the date of this Agreement will enter into, any agreement that is
inconsistent with the rights granted to the Holders of Registrable Securities or
the Market-Maker in this Agreement or otherwise conflicts with the provisions
hereof.

       (b)     AMENDMENTS AND WAIVERS. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given unless the Company and the Guarantors have obtained the written
consent of Holders of at least a majority in aggregate principal amount of the
outstanding Registrable Securities affected by such amendment, modification,
supplement, waiver or consent and, with respect to the provisions of Section 5,
the written consent of the Market-Maker; PROVIDED that no amendment,

waivers or consents pursuant to this Section 7(b) shall be by a writing executed
by each of the parties hereto.

delivery (i) if to a Holder or the Market-Maker, at the most current address
given by such Holder to the Company by means of a notice given in accordance
with the provisions of this Section 7(c), which address initially is, with
respect to the Initial Purchasers and the Market-Maker, the address of the
Initial Purchasers (including the Market-Maker) set forth in the Purchase

the address specified in the Indenture.

       (d)     SUCCESSORS AND ASSIGNS. This Agreement shall inure to the benefit
of and be binding upon the successors, assigns and transferees of each of the
parties, including, without limitation and without the need for an express
assignment, subsequent Holders; PROVIDED that nothing herein shall be deemed to
permit any assignment, transfer or other disposition of Registrable Securities
in violation of the terms of the Purchase Agreement or the Indenture. If any
transferee of any Holder shall acquire Registrable Securities in any manner,
whether by operation of law or otherwise, such Registrable Securities shall be
held subject to all the terms of this Agreement, and by taking and holding such
Registrable Securities such Person shall be conclusively deemed to have agreed
to be bound by and to perform all of the terms and provisions of this Agreement
and such Person shall be entitled to receive the benefits hereof.

                                                                              24

The Initial Purchasers (in their capacity as Initial Purchasers) shall have no
liability or obligation to the Company or the Guarantors with respect to any
failure by a Holder (other than by such Initial Purchasers) to comply with, or
any breach by any Holder (other than by such Initial Purchasers) of, any of the
obligations of such Holder under this Agreement.

       (e)     PURCHASES AND SALES OF SECURITIES. The Company and the Guarantors
shall not, and shall use their reasonable best efforts to cause their affiliates
(as defined in Rule 405 under the Securities Act) not to, purchase and then
resell or otherwise transfer any Registrable Securities, unless such Registrable
Securities are resold or transferred in a transaction registered under the
Securities Act or pursuant to Rule 144 under the Securities Act, if available.

       (f)     THIRD PARTY BENEFICIARIES. Each Holder shall be a third party
beneficiary to the agreements made hereunder between the Company and the
Guarantors, on the one hand, and the Initial Purchasers, on the other hand, and
shall have the right to enforce such agreements directly to the extent it deems
such enforcement necessary or advisable to protect its rights or the rights of
other Holders hereunder.

       (g)     COUNTERPARTS. This Agreement may be executed in any number of
counterparts and by the parties hereto in separate counterparts (which may each
be delivered in original form or by facsimile or email), each of which when so
executed shall be deemed to be an original and all of which taken together shall
constitute one and the same agreement.

       (h)     HEADINGS. The headings in this Agreement are for convenience of
reference only, are not a part of this Agreement and shall not limit or
otherwise affect the meaning hereof.

       (i)     GOVERNING LAW. This Agreement shall be governed by and construed
in accordance with the laws of the State of New York.

       (j)     MISCELLANEOUS. This Agreement contains the entire agreement
between the parties relating to the subject matter hereof and supersedes all
oral statements and prior writings with respect thereto. If any term, provision,
covenant or restriction contained in this Agreement is held by a court of
competent jurisdiction to be invalid, void or unenforceable or against public
policy, the remainder of the terms, provisions, covenants and restrictions
contained herein shall remain in full force and effect and shall in no way be
affected, impaired or invalidated. The Company, the Guarantors and the Initial
Purchasers shall endeavor in good faith negotiations to replace the invalid,
void or unenforceable provisions with valid provisions the economic effect of
which comes as close as possible to that of the invalid, void or unenforceable
provisions.

               IN WITNESS WHEREOF, the parties have executed this Agreement as
of the date first written above.
