     such period shall be reduced by an amount equal to 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 EBITDA (if
     negative), directly attributable thereto for such period and Consolidated
     Interest Expense for such period shall 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,

Incurred in connection therewith, the pro forma calculations shall be determined
in good faith by a responsible financial or accounting Officer of the Company.
If any Indebtedness bears a floating rate of interest and is being given pro
forma effect, the interest on such Indebtedness shall 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 is incurred under a revolving credit facility
and is being given pro forma effect, the interest on such Indebtedness shall be
calculated based on the average daily balance of such Indebtedness for the four
fiscal quarters subject to the pro forma calculation (but, in the case of any
Indebtedness Incurred under a revolving credit facility and Incurred other than
pursuant to clause (b)(1) of Section 4.03, only to the extent such Indebtedness

                                 THE SECURITIES

          SECTION 2.01.  FORM AND DATING. Provisions relating to the
Securities are set forth in the Rule 144A/Regulation S Appendix attached hereto
(the "Appendix"), which is hereby incorporated in and expressly made part of
this Indenture. The Initial Securities and the Trustee's certificate of
authentication shall be substantially in the form of Exhibit 1 to the Appendix
which is hereby incorporated in and expressly made a part of this Indenture. The
Exchange Securities, the Private Exchange Securities and the Trustee's
certificate of authentication shall be substantially in the form of Exhibit A,
which is

<Page>
                                                                              35

hereby incorporated in and expressly made a part of this Indenture. The
Securities may have notations, legends or endorsements required by law, stock
exchange rule, agreements to which the Company is subject, if any, or usage
(PROVIDED that any such notation, legend or endorsement is in a form acceptable
to the Company). Each Security shall be dated the date of its authentication.
The terms of the Securities set forth in the Appendix and Exhibit A are part of
the terms of this Indenture.

          SECTION 2.02.  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 signs the certificate of authentication on the Security. The
signature shall be conclusive evidence that the Security has been authenticated
under this Indenture.

          The Trustee shall authenticate and deliver Securities as set forth in
the Appendix.

          The Trustee may appoint an authenticating agent reasonably acceptable
to the Company to authenticate the Securities. Any such appointment shall be
evidenced by an instrument signed by the Trustee, a copy of which shall be
furnished to the Company. Unless limited by the terms of such appointment, an
authenticating agent may authenticate Securities whenever the Trustee may do so.
Each reference in this Indenture to authentication by the Trustee includes
authentication by such agent. An authenticating agent has the same rights as any
Registrar, Paying Agent or agent for service of notices and demands.

          SECTION 2.03.  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 Registrar
shall keep a register of the Securities and of their transfer and exchange. The
Company may have one or more co-registrars and one or more additional paying
agents. The term "Registrar" includes any co-registrar. The term "Paying Agent"
includes any additional paying agent.

<Page>
                                                                              36

          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 any 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 7.07. The Company or any
Wholly Owned Subsidiary incorporated or organized within the United States of
America may act as Paying Agent or Registrar.

          The Company initially appoints the Trustee as Registrar and Paying
Agent in connection with 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 an
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
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 2.04.  PAYING AGENT TO HOLD MONEY IN TRUST. On or prior to
each due date of the principal of and interest on any Security, the Company
shall deposit with the Paying Agent a sum sufficient to pay such principal and
interest when so becoming due. The Company shall require each Paying Agent
(other than the Trustee) to agree in writing that the Paying Agent shall hold in
trust for the benefit of Securityholders or the Trustee all money held by the
Paying Agent for the payment of principal of or interest on the Securities and
shall notify the Trustee of any default by the Company 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 to pay all money held by it to
the Trustee and to account for any funds disbursed by the Paying Agent. Upon
complying with this Section 2.04, the Paying Agent shall have no further
liability for the money delivered to the Trustee.

<Page>
                                                                              37

          SECTION 2.05.  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 all Securityholders and shall otherwise comply
with TIA ss. 312(a). If the Trustee is not the Registrar, the Company shall
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 2.06. TRANSFER AND EXCHANGE. The Securities shall be
 issued in registered form and shall be transferable only upon the surrender of
 a Security for registration of transfer. When a Security is presented to the
 Registrar with a request to register a transfer, the Registrar shall register
 the transfer as requested if the requirements of this Indenture and Section
 8-401(1) of the Uniform Commercial Code are met. When Securities are presented
 to the Registrar with a request to exchange them for an equal principal amount
 of Securities of other denominations, the Registrar shall make the exchange as
 requested if the same requirements are met.

          To permit registration of transfers and exchanges, the Company shall
execute and the Trustee shall authenticate Securities at the Registrar's
request. The Company or the Registrar may require a Holder, among other things,
to pay a sum sufficient to pay all taxes, assessments or other governmental
charges in connection with any transfer or exchange pursuant to this Section.
The Company shall not be required to make and the Registrar need not register
transfers or exchanges of Securities selected for redemption (except, in the
case of Securities to be redeemed in part, the portion thereof not to be
redeemed) or any Securities for a period of 15 days before a selection of
Securities to be redeemed or 15 days before an interest payment date.

          Prior to the due presentation for registration of transfer of any
Security, the Company, the Subsidiary Guarantors, the Trustee, the Paying Agent,
and the Registrar may deem and treat the Person in whose name a Security is
registered as the absolute owner of such Security for the purpose of receiving
payment of principal of and (subject to paragraph 2 of the Securities) interest,
if any, on such Security and for all other purposes whatsoever, whether or not
such Security is overdue, and none of the Company, any Subsidiary Guarantor, the
Trustee, the Paying Agent, or the Registrar shall be affected by notice to the
contrary.

<Page>
                                                                              38

          All Securities issued upon any transfer or exchange pursuant to the
terms of this Indenture shall evidence the same debt and shall be entitled to
the same benefits under this Indenture as the Securities surrendered upon such
transfer or exchange.

          SECTION 2.07.  REPLACEMENT 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 and the Holder 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. The Company and the Trustee may charge the Holder for
their expenses in replacing a Security.

          Every replacement Security is an additional obligation of the Company.

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

          If a Security is replaced pursuant to Section 2.07, 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 2.09.  TEMPORARY SECURITIES. Until definitive Securities are
ready for delivery, the Company

<Page>
                                                                              39

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 and deliver them in exchange for temporary
Securities.

          SECTION 2.10.  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 and
destroy (subject to the record retention requirements of the Exchange Act) all
Securities surrendered for registration of transfer, exchange, payment or
cancellation and deliver a certificate of such destruction to the Company unless
the Company directs the Trustee to deliver canceled Securities to the Company.
The Company may not issue new Securities to replace Securities it has redeemed,
paid or delivered to the Trustee for cancellation.

          SECTION 2.11.  DEFAULTED INTEREST. If the Company defaults in a
payment of interest on the Securities, the Company shall pay defaulted interest
(plus interest on such defaulted interest to the extent lawful) in any lawful
manner. The Company may pay the defaulted interest to the persons who are
Securityholders on a subsequent special record date. The Company shall fix or
cause to be fixed any such special record date and payment date to the
reasonable satisfaction of the Trustee and shall promptly mail to each
Securityholder a notice that states the special record date, the payment date
and the amount of defaulted interest to be paid.

          SECTION 2.12.  CUSIP NUMBERS. The Company in issuing the Securities
may use numbers assigned by the Committee on Uniform Securities Identification
Procedures ("CUSIP") and corresponding International Securities Identification
Numbers ("ISIN") (if then generally in use) and, if so, the Trustee shall use
CUSIP 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 numbers. The Company

<Page>
                                                                              40

shall promptly notify the Trustee of any change in the CUSIP or ISIN numbers.

          SECTION 2.13.  ADDITIONAL SECURITIES. The Company shall be entitled,
subject to its compliance with Section 4.03, to issue Additional Securities
under this Indenture which shall have identical terms as the initial Securities
issued on the Issue Date, other than with respect to the date of issuance and
issue price. The Initial Securities issued on the Issue Date, any Additional
Securities and all Exchange Securities or Private Exchange Securities issued in
exchange therefor shall be treated as a single class for all purposes under this
Indenture.

          With respect to any Additional Securities, the Company shall set forth
in a resolution of the Board of Directors and an Officers' Certificate, a copy
of each which shall be delivered to the Trustee, the following information:

          (1)     the aggregate principal amount of such Additional Securities
     to be authenticated and delivered pursuant to this Indenture;

          (2)     the issue price, the issue date and the CUSIP number of such
     Additional Securities; PROVIDED, HOWEVER, that no Additional Securities may
     be issued at a price that would cause such Additional Securities to have
     "original issue discount" within the meaning of Section 1273 of the Code;
     and

          (3)     whether such Additional Securities shall be Transfer
     Restricted Securities and issued in the form of Securities as set forth in
     the Appendix to this Indenture or shall be issued in the form of Exchange
     Securities as set forth in Exhibit A.

                                    ARTICLE 3

                                   REDEMPTION

          SECTION 3.01.  NOTICES TO TRUSTEE. If the Company elects to redeem
Securities pursuant to paragraph 5 of the Securities, it shall notify the
Trustee in writing of the redemption date, the principal amount of Securities to
be redeemed and the paragraph of the Securities pursuant to which the redemption
will occur.

          The Company shall give each notice to the Trustee provided for in this
Section 3.01 at least 45 days but not

<Page>
                                                                              41

 more than 60 days before the redemption date unless the Trustee consents to a
 shorter period. Such notice shall be accompanied by an Officers' Certificate
 from the Company to the effect that such redemption will comply with the
 conditions herein.

          SECTION 3.02.  SELECTION OF SECURITIES TO BE REDEEMED. If fewer than
all the Securities are to be redeemed, the Trustee shall select the Securities
to be redeemed pro rata or by lot or by a method that complies with applicable
legal and securities exchange requirements, if any, and that the Trustee in its
sole discretion shall deem to be fair and appropriate and in accordance with
methods generally used at the time of selection by fiduciaries in similar
circumstances. The Trustee shall make the selection from outstanding Securities
not previously called for redemption. The Trustee may select for redemption
portions of the principal of Securities that have denominations larger than
$1,000. Securities and portions of them the Trustee selects shall be in
principal amounts of $1,000 or a whole multiple of $1,000. Provisions of this
Indenture that apply to Securities called for redemption also apply to portions
of Securities called for redemption. The Trustee shall notify the Company
promptly of the Securities or portions of Securities to be redeemed.

          SECTION 3.03.  NOTICE OF REDEMPTION. At least 30 days but not more
than 60 days before a date for redemption of Securities, the Company shall mail
or cause to be mailed a notice of redemption by first-class mail to each Holder
of Securities to be redeemed at such Holder's registered address.

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

          (1)     the redemption date;

          (2)     the redemption price;

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

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

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

<Page>
                                                                              42

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

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

          At the Company's request, the Trustee shall give the notice of
redemption in the Company's name and at the Company's expense. In such event,
the Company shall provide the Trustee with the information required by this
Section 3.03.

          SECTION 3.04.  EFFECT OF NOTICE OF REDEMPTION. Once notice of
redemption is mailed, Securities called for redemption become due and payable on
the redemption date and at the redemption price stated in the notice. Upon
surrender to the Paying Agent, such Securities shall be paid at the redemption
price stated in the notice, plus accrued interest to the redemption date
(subject to the right of Holders of record on the relevant record date to
receive interest due on the related interest payment date). Failure to give
notice or any defect in the notice to any Holder shall not affect the validity
of the notice to any other Holder.

          SECTION 3.05.  DEPOSIT OF REDEMPTION PRICE. On or prior to the
redemption date, the Company shall deposit with the Trustee or the Paying Agent
(or, if the Company or a Subsidiary is the Trustee or the Paying Agent, shall
segregate and hold in trust) money sufficient to pay the redemption price of and
accrued interest on all Securities to be redeemed on that date other than
Securities or portions of Securities called for redemption which have been
delivered by the Company to the Trustee for cancellation. The Trustee or the
Paying Agent will promptly return to the Company any money deposited with the
Trustee or the Paying Agent by the Company in excess of the amounts necessary to
pay the redemption price of and accrued interest on all Securities to be
redeemed.

          SECTION 3.06.  SECURITIES REDEEMED IN PART. Upon surrender of a
Security that is redeemed in part, the Company shall execute and the Trustee
shall authenticate for the Holder (at the Company's expense) a new Security
equal in principal amount to the unredeemed portion of the Security surrendered.

                                                                              43

                                    ARTICLE 4

                                    COVENANTS

          SECTION 4.01.  PAYMENT OF SECURITIES. The Company shall promptly pay
or cause to be paid 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 money
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.

          SECTION 4.02.  SEC REPORTS.

          (a)  Notwithstanding that the Company may not be subject to the
reporting requirements of Section 13 or 15(d) of the Exchange Act, the Company
shall file with the SEC (to the extent the SEC will accept such filings) and, in
any event, shall provide the Trustee and Securityholders with such annual
reports and such information, documents and other reports as are specified in
Sections 13 and 15(d) of the Exchange Act and applicable to a U.S. corporation
subject to such Sections, at the times specified for the filings of such
information, documents and reports under such Sections; PROVIDED, HOWEVER, (x)
if the Company is exempt from the requirements of Section 13(a) or 15(d) of the
Exchange Act under Section 12h-5 of the Exchange Act, the Company shall not be
required to file such reports and documents with the SEC under Section 13(a) or
15(d) of the Exchange Act (or any successor provisions thereto) or provide such
annual reports and such information, documents and other reports to the Trustee
and the Securityholders so long as (i) Parent files such annual reports and such
information, documents and other reports with the SEC, (ii) Parent, the Company
and each Subsidiary Guarantor are in compliance with the requirements set forth
in Rule 3-10 of Regulation S-X under the Exchange Act and (iii) the Company
provides the Trustee and Securityholders with such annual reports and such
information, documents and other reports and (y) if the Issue Date occurs prior
to March 31, 2003, the Company shall not be required to prepare, file

<Page>
                                                                              44

with the SEC or provide the Trustee or securityholders a Form 10-K for the year
ended December 31, 2002.

          (b)  At any time that any of the Company's Subsidiaries are
Unrestricted Subsidiaries, the quarterly and annual financial information
required by Section 4.02(a) shall include a reasonably detailed presentation,
either on the face of the financial statements or in the footnotes thereto, and
in "Management's Discussion and Analysis of Financial Condition and Results of
Operations," of the financial condition and results of operations of the Company
and its Restricted Subsidiaries separate from the financial condition and
results of operations of the Unrestricted Subsidiaries of the Company.

          (c)  The Company shall furnish to the Holders of the Securities and to
prospective investors, upon the requests of such Holders, any information
required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act so
long any Securities are not freely transferable under the Securities Act.

          (d)  The Company shall comply with the other provisions of
TIA Section 314(a).

          SECTION 4.03.  LIMITATION ON INDEBTEDNESS.

          (a)  The Company shall not, and shall not permit any Restricted
Subsidiary to, Incur, directly or indirectly, any Indebtedness; PROVIDED,
HOWEVER, that the Company and its Restricted Subsidiaries shall be entitled to
Incur Indebtedness if, on the date of such Incurrence and after giving effect
thereto on a PRO FORMA basis, no Default has occurred and is continuing and the
Consolidated Coverage Ratio exceeds (i) 2.00 to 1,00, if such Incurrence occurs
on or prior to March 31, 2005, or (ii) 2.25 to 1.00, if such Incurrence occurs
after such date.

          (b)  Notwithstanding Section 4.03(a), the Company and the Restricted
Subsidiaries shall be entitled to Incur any or all of the following
Indebtedness:

          (1)  Indebtedness incurred by the Company and the Restricted
     Subsidiaries pursuant to any Revolving Credit Facility; PROVIDED, HOWEVER,
     that, immediately after giving effect to any such Incurrence, the aggregate
     principal amount of all Indebtedness Incurred under this Section 4.03
     (b)(1) and then outstanding does not exceed the greater of (A) $65.0
     million less the sum of all principal payments with respect to such
     Indebtedness pursuant to Section 4.06(a)(3)(A) that are

     Subsidiaries;

          (2)  Indebtedness Incurred by the Company and its Restricted
     Subsidiaries pursuant to any Term Loan Facility; PROVIDED, HOWEVER, that,

          Credit Agreement, as determined in good faith by the

          Company's Board of Directors, whose determination shall be conclusive;
          and

               (H)    any encumbrance or restriction imposed on any Consolidated
          Managed Subsidiary by (and for the benefit of) the Company or any
          Subsidiary Guarantor; and

          (2)  with respect to clause (c) only,

               (A)    any encumbrance or restriction consisting of customary
          nonassignment provisions in leases governing leasehold interests or
          contracts to the extent such provisions restrict the transfer of the
          lease or the property leased thereunder or the contract;

               (B)    any encumbrance or restriction contained in security
          agreements or mortgages securing Indebtedness of a Restricted
          Subsidiary to the extent such encumbrance or restriction restricts the
          transfer of the property subject to such Security agreements or
          mortgages; and

               (C)    any encumbrance or restriction with respect to assets of a
          Restricted Subsidiary imposed pursuant to an agreement entered into
          for the sale or disposition of such assets.

          SECTION 4.06.  LIMITATION ON SALES OF ASSETS AND SUBSIDIARY
                         STOCK.

          (a)  The Company shall not, and shall not permit any Restricted
Subsidiary to, directly or indirectly, consummate any Asset Disposition
unless:

          (1)  the Company or such Restricted Subsidiary receives consideration
     at the time of such Asset Disposition at least equal to the Fair Market
     Value (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 thereof received by the Company
     or such Restricted Subsidiary 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)

<Page>
                                                                              56

               (A)    FIRST, to the extent the Company elects (or is required by
          the terms of any Indebtedness), to prepay, repay, redeem or purchase
          Senior Indebtedness of the Company or a Subsidiary Guarantor or
          Indebtedness (other than any Disqualified Stock) of a Wholly Owned
          Subsidiary (in each case other than Indebtedness owed to the Company
          or an Affiliate of the Company) within one year from the later of the
          date of such Asset Disposition or the receipt of such Net Available
          Cash;

               (B)    SECOND, to the extent of the balance of such Net Available
          Cash after application in accordance with Section 4.06(a)(3)(A), to
          the extent the Company elects, to acquire (or enter into a binding
          agreement to acquire, so long as such acquisition shall be consummated
          within 90 days after the end of the one-year period referred to below)
          Additional Assets within one year from the later of the date of such
          Asset Disposition or the receipt of such Net Available Cash; and

               (C)    THIRD, to the extent of the balance of such Net Available
          Cash after application in accordance with Section 4.06(a)(3)(A) and
          Section 4.06(a)(3) (B), to make an Offer to the holders of the
          Securities (and to holders of other Senior Subordinated Indebtedness
          of the Company or a Subsidiary Guarantor designated by the Company) to
          purchase Securities (and such other Senior Subordinated Indebtedness
          of the Company or a Subsidiary Guarantor) pursuant to and subject to
          the conditions of Section 4.06(b);

          PROVIDED, HOWEVER, that in connection with any prepayment, repayment
          or purchase of Indebtedness pursuant to Section 4.06(a)(3)(A) or
          Section 4.06(a)(3)(C), the Company or such Restricted Subsidiary shall
          permanently retire such Indebtedness and shall cause the related loan
          commitment (if any) to be permanently reduced in an amount equal to
          the principal amount so prepaid, repaid or purchased.

          Notwithstanding the foregoing provisions of this Section 4.06, the
Company and the Restricted Subsidiaries shall not be required to apply any Net
Available Cash in accordance with this Section 4.06(a) except to the extent that
the aggregate Net Available Cash from all Asset Dispositions which is not
applied in accordance with this

<Page>
                                                                              57

Section 4.06(a) exceeds $10.0 million. Pending application of Net Available Cash
pursuant to this Section 4.06(a), such Net Available Cash shall be invested in
Temporary Cash Investments or applied to temporarily reduce revolving credit
indebtedness.

          For the purposes of this Section 4.06(a), the following are deemed to
be cash or cash equivalents:

          (1)  the assumption of Indebtedness of the Company (other than
     obligations in respect of Disqualified Stock of the Company) or any
     Restricted Subsidiary (other than obligations in respect of Disqualified
     Stock or Preferred Stock of a Subsidiary Guarantor) and the release of the
     Company or such Restricted Subsidiary from all liability on such
     Indebtedness in connection with such Asset Disposition; and

          (2)  securities received by the Company or any Restricted Subsidiary
     from the transferee that are converted by the Company or such Restricted
     Subsidiary into cash within 90 days, to the extent of cash received in that
     conversion.

          (b)  In the event of an Asset Disposition that requires the purchase
of Securities (and other Senior Subordinated Indebtedness of the Company or a
Subsidiary Guarantor) pursuant to Section 4.06(a)(3)(C), the Company shall
purchase Securities tendered pursuant to an offer by the Company for the
Securities (and such other Senior Subordinated Indebtedness of the Company or a
Subsidiary Guarantor) (the "Offer") at a purchase price of 100% of their
principal amount (or, if other than the Securities, 100% of their principal
amount or, in the event such other Senior Subordinated Indebtedness of the
Company or a Subsidiary Guarantor was issued with significant original issue
discount, 100% of the accreted value thereof) without premium, plus accrued but
unpaid interest (or, in respect of such other Senior Subordinated Indebtedness
of the Company or a Subsidiary Guarantor, such lesser price, if any, as may be
provided for by the terms of such Senior Subordinated Indebtedness) in
accordance with the procedures (including prorating in the event of
oversubscription) set forth in Section 4.06(c). If the aggregate purchase price
of Securities (and any other Senior Subordinated Indebtedness) tendered pursuant
to the Offer exceeds the Net Available Cash allotted to their purchase, the
Company shall select the Securities and other Senior Subordinated Indebtedness
to be purchased on a pro rata basis but in round denominations, which in the
case of the Securities will be denominations of $1,000 principal amount or
multiples thereof. The Company

<Page>
                                                                              58

shall not be required to make an Offer to purchase Securities (and other Senior
Subordinated Indebtedness of the Company or a Subsidiary Guarantor) pursuant to
this Section 4.06 if the Net Available Cash available therefor is less than
$10.0 million (which lesser amount shall be carried forward for purposes of
determining whether such an Offer is required with respect to the Net Available
Cash from any subsequent Asset Disposition). Upon completion of an Offer
pursuant to Section 4.06, Net Available Cash will be deemed to be reduced by the
aggregate amount of such offer.

          (c) (1) Promptly, and in any event within 10 days after the Company
     becomes obligated to make an Offer, the Company shall deliver to the
     Trustee and send, by first-class mail to each Holder, a written notice
     stating that the Holder may elect to have his Securities purchased by the
     Company either in whole or in part (subject to prorating as described in
     Section 4.06(b) in the event the Offer is oversubscribed) in integral
     multiples of $1,000 of principal amount, at the applicable purchase price.
     The notice shall specify a purchase date not less than 30 days nor more
     than 60 days after the date of such notice (the "Purchase Date") and shall
     contain such information concerning the business of the Company which the
     Company in good faith believes will enable such Holders to make an informed
     decision and all instructions and materials necessary to tender Securities
     pursuant to the Offer, together with the information contained in Section
     4.06(c)(3).

          (2)  Not later than the date upon which written notice of an Offer is
     delivered to the Trustee as provided below, the Company shall deliver to
     the Trustee an Officers' Certificate as to (A) the amount of the Offer (the
     "Offer Amount"), including information as to any other Senior Subordinated
     Indebtedness included in the Offer, (B) the allocation of the Net Available
     Cash from the Asset Dispositions pursuant to which such Offer is being made
     and (C) the compliance of such allocation with the provisions of Section
     4.06(a) and (b). On such date, the Company shall also irrevocably 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) in Temporary Cash
     Investments, maturing on the last day prior to the Purchase Date or on the
     Purchase Date if funds are immediately available by open of business, an
     amount equal to the Offer Amount to be held for payment in accordance with
     the provisions of this Section 4.06.

<Page>
                                                                              59

     If the Offer includes other Senior Subordinated Indebtedness, the deposit
     described in the preceding sentence may be made with any other paying agent
     pursuant to arrangements reasonably satisfactory to the Trustee. Upon the
     expiration of the period for which the Offer remains open (the "Offer
     Period"), the Company shall deliver to the Trustee for cancellation the
     Securities or portions thereof which have been properly tendered to and are
     to be accepted by the Company. The Trustee shall, on the Purchase Date,
     mail or deliver payment (or cause the delivery of payment) to each
     tendering Holder in the amount of the purchase price. In the event that the
     aggregate purchase price of the Securities delivered by the Company to the
     Trustee is less than the Offer Amount applicable to the Securities, the
     Trustee shall deliver the excess to the Company immediately after the
     expiration of the Offer Period for application in accordance with this
     Section 4.06.

          (3)  Holders electing to have a Security purchased shall be required
     to surrender the Security, with an appropriate form duly completed, to the
     Company at the address specified in the notice at least three Business Days
     prior to the Purchase Date. Holders shall be entitled to withdraw their
     election if the Trustee or the Company receives not later than one Business
     Day prior to the Purchase Date, a telex, facsimile transmission or letter
     setting forth the name of the Holder, the principal amount of the Security
     which was delivered for purchase by the Holder and a statement that such
     Holder is withdrawing his election to have such Security purchased. Holders
     whose Securities are purchased only in part shall be issued new Securities
     equal in principal amount to the unpurchased portion of the Securities
     surrendered.

          (4)  At the time the Company delivers Securities to the Trustee which
     are to be accepted for purchase, the Company shall also deliver an
     Officers' Certificate stating that such Securities are to be accepted by
     the Company pursuant to and in accordance with the terms of this Section
     4.06. A Security shall be deemed to have been accepted for purchase at the
     time the Trustee, directly or through an agent, mails or delivers payment
     therefor to the surrendering Holder.

          (d)  The Company shall comply, to the extent applicable, with the
requirements of Section 14(e) of the Exchange Act and any other securities laws
or regulations in connection with the repurchase of Securities pursuant to

<Page>
                                                                              60

this Section 4.06. To the extent that the provisions of any securities laws or
regulations conflict with provisions of this Section 4.06, the Company shall
comply with the applicable securities laws and regulations and shall not be
deemed to have breached its obligations under this Section 4.06 by virtue of its
compliance with such securities laws or regulations.

          SECTION 4.07.  LIMITATION ON AFFILIATE TRANSACTIONS.

          (a)  The Company shall not, and shall not permit any Restricted
Subsidiary to, enter into or permit to exist any transaction (including the
purchase, sale, lease or exchange of any property, employee compensation
arrangements or the rendering of any service) with, or for the benefit of, any
Affiliate of the Company (an "Affiliate Transaction") unless:

          (1)  the terms of the Affiliate Transaction are no less favorable to
     the Company or such Restricted Subsidiary than those that could be obtained
     at the time of the Affiliate Transaction in arm's-length dealings with a
     Person who is not an Affiliate;

          (2)  if such Affiliate Transaction involves an amount in excess of
     $5,0 million, the terms of the Affiliate Transaction are set forth in
     writing and a majority of the non-employee directors of the Company
     disinterested with respect to such Affiliate Transaction have determined in
     good faith that the criteria set forth in Section 4.07(a)(1) are satisfied
     and have approved the relevant Affiliate Transaction as evidenced by a
     resolution of such Board of Directors; and

          (3)  if such Affiliate Transaction involves an amount in excess of
     $15.0 million, the Board of Directors of the Company shall also have
     received a written opinion from an Independent Qualified Party to the
     effect that such Affiliate Transaction is fair, from a financial
     standpoint, to the Company and its Restricted Subsidiaries or is not less
     favorable to the Company and its Restricted Subsidiaries than could
     reasonably be expected to be obtained at the time in an arm's-length
     transaction with a Person who was not an Affiliate. For purposes of this
     clause (3) only, any contract or series of related contracts for the
     rendering of services entered into in the ordinary course of business by
     the Company or any Restricted Subsidiary with any other Person will not be
     deemed to

<Page>
                                                                              61

     be in excess of $15.0 million if, when entered into, (x) the payments made
     by the Company and the Restricted Subsidiaries and (y) the value of
     services performed by the Company and the Restricted Subsidiaries in
     connection with such contract or series of related contracts do not exceed,
     and are not then reasonably expected by the Board of Directors of the
     Company in its good faith judgment to exceed, $15.0 million in any year.

          (b)  The provisions of Section 4.07(a) shall not prohibit:

          (1)  any Investment (other than a Permitted Investment) or other
     Restricted Payment (or any transaction that would constitute a Restricted
     Payment but for the exclusions from the definition thereof (other than
     Permitted Investments)), in each case permitted to be made pursuant to
     Section 4.04;

          (2)  any issuance of securities, or other payments, awards or grants
     in cash, securities or otherwise pursuant to, or the funding of, employment
     arrangements, stock options and stock ownership plans approved by the Board
     of Directors of the Company;

          (3)  loans or advances to employees in the ordinary course of business
     in accordance with the past practices of the Company or its Restricted
     Subsidiaries, but in any event not to exceed $2.5 million in the aggregate
     outstanding at any one time;

          (4)  transactions and agreements between or among the Company and the
     Restricted Subsidiaries;

          (5)  the payment of reasonable fees to directors of the Company and
     its Restricted Subsidiaries who are not employees of the Company or its
     Restricted Subsidiaries, and compensation and employee benefit arrangements
     paid to, and indemnity provided for the benefit of, directors, officers, or
     employees of the Company and its Restricted Subsidiaries in the ordinary
     course of business;

          (6)  any transaction with a Restricted Subsidiary or joint venture or
     similar entity which would constitute an Affiliate Transaction solely
     because the Company or a Restricted Subsidiary owns an equity interest in
     or otherwise controls such Restricted Subsidiary, joint venture or similar
     entity;

<Page>
                                                                              62

          (7)  transactions or agreements between the Company and its Restricted
     Subsidiaries, on the one hand, and any Managed Entity that is not a
     Consolidated Managed Subsidiary, on the other hand; PROVIDED, HOWEVER, that
     any such transactions or agreements are no less favorable, in the
     aggregate, to the Company than arrangements in place as of the Issue Date;

          (8)  the issuance or sale of any Capital Stock (other than
     Disqualified Stock) of the Company; and

          (9)  any transaction or agreement described in the Offering Circular
     under "Certain Relationships and Related Transactions" and any amendment or
     renewal thereof on terms no less favorable in the aggregate to the Company
     and its Subsidiaries.

          SECTION 4.08.  LIMITATION ON THE SALE OR ISSUANCE OF CAPITAL STOCK OF
RESTRICTED SUBSIDIARIES. The Company

          (a)  shall not, and shall not permit any Restricted Subsidiary to,
     sell, lease, transfer or otherwise dispose of any Capital Stock of any
     Restricted Subsidiary to any Person (other than (x) the Company or a Wholly
     Owned Subsidiary and (y) in the case of a Consolidated Managed Subsidiary,
     another nominee shareholder (PROVIDED that such Consolidated Managed
     Subsidiary does not cease to be a Consolidated Managed Subsidiary as a
     result of such disposition)) and

          (b)  shall not permit any Restricted Subsidiary to issue any of its
     Capital Stock (other than, if necessary, shares of its Capital Stock
     constituting directors' or other legally required qualifying shares) to any
     Person (other than to the Company or a Wholly Owned Subsidiary),

unless, in the case of either Section 4.08(a) or (b):

          (i)     immediately after giving effect to such issuance, sale or
     other disposition, neither the Company nor any of its Subsidiaries own any
     Capital Stock of such Restricted Subsidiary or

          (ii)    immediately after giving effect to such issuance, sale or
     other disposition, such Restricted Subsidiary would no longer constitute a
     Restricted Subsidiary and any Investment in such Person remaining after
     giving effect thereto is treated as a new Investment by the Company and
     such Investment would be permitted to be made under Section 4.04 if made on
     the date of such issuance, sale or other disposition.

                                                                              63

          SECTION 4.09.  CHANGE OF CONTROL.

          (a)  Upon the occurrence of a Change of Control, each Holder shall
have the right to require that the Company repurchase such Holder's Securities
at a purchase price in cash equal to 101% of the principal amount thereof on the
date of purchase plus accrued and unpaid interest, if any, to the date of
purchase (subject to the right of holders of record on the relevant record date
to receive interest due on the relevant interest payment date), in accordance
with the terms contemplated in Section 4.09(b). In the event that at the time of
such Change of Control the terms of any Senior Indebtedness of the Company
restrict or prohibit the purchase of Securities pursuant to this Section 4.09,
then prior to the mailing of the notice to Holders provided for in Section
4.09(b) below but in any event within 30 days following any Change of Control,
the Company shall (1) repay in full all such Senior Indebtedness or (2) obtain
the requisite consents under the agreements governing all such Senior
Indebtedness to permit the repurchase of the Securities as provided for in
Section 4.09(b).

          (b)  Within 30 days following any Change of Control, the Company shall
mail a notice to each Holder with a copy to the Trustee (the "Change of Control
Offer") stating:

          (1)  that a Change of Control has occurred and that such Holder has
     the right to require the Company to purchase such Holder's Securities at a
     purchase price in cash equal to 101% of the principal amount thereof on the
     date of purchase, plus accrued and unpaid interest, if any, to the date of
     purchase (subject to the right of Holders of record on the relevant record
     date to receive interest on the relevant interest payment date);

          (2)  the circumstances and relevant facts regarding such Change of
     Control (including information with respect to pro forma historical income,
     cash flow and capitalization, in each case after giving effect to such
     Change of Control);

          (3)  the purchase date (which shall be no earlier than 30 days nor
     later than 60 days from the date such notice is mailed); and

          (4)  the instructions, as determined by the Company, consistent with
     this Section 4.09, that a Holder must follow in order to have its
     Securities purchased.

                                                                              64

          (c)  Holders electing to have a Security purchased shall be required
to surrender the Security, with an appropriate form duly completed, to the
Company at the address specified in the notice at least three Business Days
prior to the purchase date. Holders shall be entitled to withdraw their election
if the Trustee or the Company receives not later than one Business Day prior to
the purchase date, a telegram, telex, facsimile transmission or letter setting
forth the name of the Holder, the principal amount of the Security which was
delivered for purchase by the Holder and a statement that such Holder is
withdrawing his election to have such Security purchased.

          (d)  On the purchase date, all Securities purchased by the Company
under this Section 4.09 shall be delivered by the Company to the Trustee for
cancellation, and the Company shall pay the purchase price plus accrued and
unpaid interest, if any, to the Holders entitled thereto.

          (e)  Notwithstanding the foregoing provisions of this Section 4.09,
the Company shall not be required to make a Change of Control Offer upon a
Change of Control if a third party makes the Change of Control Offer in the
manner, at the times and otherwise in compliance with the requirements set forth
in Section 4.09(b) and purchases all Securities validly tendered and not
withdrawn under such Change of Control Offer.

          (f)  The Company shall comply, to the extent applicable, with the
requirements of Section 14(e) of the Exchange Act and any other securities laws
or regulations in connection with the repurchase of Securities pursuant to this
Section 4.09. To the extent that the provisions of any securities laws or
regulations conflict with provisions of this Section 4.09, the Company shall
comply with the applicable securities laws and regulations and shall not be
deemed to have breached its obligations under this Section 4.09 by virtue of its
compliance with such securities laws or regulations.

          SECTION 4.10.  LIMITATION ON LINE OF BUSINESS AND OPERATIONS. (a) The
Company shall not, and shall not permit any Restricted Subsidiary, to engage in
any business other than a Related Business.

          (b)  The Company shall not permit any Consolidated Managed Subsidiary
that is not a Subsidiary Guarantor to engage in any activities, hold any assets
or conduct any business that is not directly related to the performance of

<Page>
                                                                              65

anatomic pathology services in the geographic territory in which such
Consolidated Managed Subsidiary operates.

          SECTION 4.11.  FUTURE GUARANTORS. The Company shall cause each future
Foreign Restricted Subsidiary that Guarantees any other Indebtedness of the
Company and each future Domestic Restricted Subsidiary that Incurs any
Indebtedness (other than in the case of any Consolidated Managed Subsidiary,
Indebtedness owed to the Company or any Subsidiary Guarantor) to, at the same
time, execute and deliver to the Trustee a Guaranty Agreement pursuant to which

          SECTION 5.01. WHEN COMPANY MAY MERGE OR TRANSFER ASSETS.

          (a)  The Company shall not consolidate with or merge with or into, or
convey, transfer or lease, in one transaction or a series of transactions,
directly or indirectly, all or substantially all its assets to, any Person,

          (1) the resulting, surviving or transferee Person (the "Successor
     Company") shall be a Person organized and existing under the laws of the
     United States of America, any State thereof or the District of Columbia and
     the Successor Company (if not the Company) shall expressly assume, by an
     indenture supplemental hereto, executed and delivered to the Trustee, in
     form reasonably satisfactory to the Trustee, all the obligations of the
     Company under the Securities and this Indenture;

          (2)  immediately after giving pro forma effect to such transaction
     (and treating any Indebtedness which becomes an obligation of the Successor
     Company or any Subsidiary as a result of such transaction as having been
     Incurred by such Successor Company or such Subsidiary at the time of such
     transaction), no Default shall have occurred and be continuing;

         (3)  immediately after giving pro forma effect to such transaction, the
     Successor Company would be able to Incur an additional $1.00 of
     Indebtedness pursuant to Section 4.03(a); and

          (4)  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 this Indenture.

PROVIDED, HOWEVER, that clause (3) shall not be applicable to (A) the Company or
a Restricted Subsidiary consolidating with, merging into, conveying,

the Company or a Restricted Subsidiary in another jurisdiction.

          For purposes of this Section 5.01(a), 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 (other than to
the Company or any Wholly Owned Subsidiary), which properties and assets, if
held by the Company instead of such Subsidiaries, would constitute all or
substantially all of the properties and assets of the Company on a consolidated
basis, shall be deemed to be the transfer of all or substantially all of the
properties and assets of the Company.

          The Successor Company (if not the Company) shall be the successor to
the Company and shall succeed to, and be substituted for, and may exercise every
right and power of, the Company under this Indenture, and the predecessor
Company, except in the case of a lease, shall be released from the obligation to
pay the principal of and interest on the Securities.

          (b)  The Company shall not permit any Subsidiary Guarantor to
consolidate with or merge with or into, or convey, transfer or lease, in one
transaction or a series of transactions, all or substantially all of its assets
to any Person unless:

          (1)  except in the case of a Subsidiary Guarantor that has been
     disposed of in its entirety to another Person (other than to the Company or
     a Subsidiary of the Company), whether through a merger, consolidation or
     sale of Capital Stock or assets, if in connection therewith the Company
     provides an Officers' Certificate to the Trustee to the effect that the
     Company will comply with its obligations under Section 4.06 in respect of
     such disposition, the resulting, surviving or transferee Person (if not
     such Subsidiary) shall be a Person organized and existing under the laws of
     the jurisdiction under which such Subsidiary was organized or under the
     laws of the United States of America, or any State thereof or the District
     of Columbia, and such Person shall expressly assume, by a Guaranty
     Agreement, in a form satisfactory to the Trustee, all the obligations of
     such Subsidiary, if any, under its Subsidiary Guaranty;

          (2)  immediately after giving effect to such transaction or
     transactions on a pro forma basis (and treating any Indebtedness which
     becomes an obligation

     of the resulting, surviving or transferee Person as a result of such
     transaction as having been issued by such Person at the time of such
     transaction), no Default shall have occurred and be continuing; and

          (3)  the Company delivers to the Trustee an Officers' Certificate and
     an Opinion of Counsel, each stating that such consolidation, merger or
     transfer and such Guaranty Agreement, if any, complies with this Indenture;

PROVIDED, HOWEVER, that this Section 5.01(b) shall not be applicable to any
Subsidiary Guarantor that consolidates with, merges with or into or conveys,
transfers or leases all or substantially all of its assets to the Company or
another Subsidiary Guarantor.

          (c)  Pursuant to this Indenture, so long as the Existing Contingent
Notes have not been satisfied in full and cash remains in the Contingent Note
Reserve, Parent agrees not to merge with or into, or convey, transfer or lease,
in one transaction or a series of transactions, all or substantially all of its
assets to any Person unless:

          (1)  the resulting, surviving or transferee Person (if not Parent)
     shall be a Person organized and existing under the laws of the jurisdiction
     under which Parent was organized or under the laws of the United States of
     America, or any State thereof or the District of Columbia, and such Person
     shall expressly assume all the obligations of Parent, if any, under this
     Indenture;

          (2)  immediately after giving effect to such transaction or
     transactions on a pro forma basis (and treating any Indebtedness which
     becomes an obligation of the resulting, surviving or transferee Person as a
     result of such transaction as having been issued by such Person at the time
     of such transaction), no Default shall have occurred and be continuing, and

          (3)  the Company delivers to the Trustee an Officers' Certificate and
     an Opinion of Counsel, each stating that such consolidation, merger or
     transfer and such assumption agreement, if any, complies with this
     Indenture.

                              DEFAULTS AND REMEDIES

          SECTION 6.01.  EVENTS OF DEFAULT. An "Event of Default" occurs if:

          (1)  the Company defaults in any payment of interest on any Security
     when the same becomes due and payable, whether or not such payment shall be
     prohibited by Article 10, and such default continues for a period of 30
     days;

          (2)  the Company (i) defaults in the payment of the principal of any
     Security when the same becomes due and payable at its Stated Maturity, upon
     optional redemption, upon declaration of acceleration or otherwise, whether

     purchase Securities validly tendered when required under Section 4.06 or
     4.09) and such failure continues for 30 days after the notice specified
     below;

          (5)  the Company or any Subsidiary Guarantor fails to comply with any
     of its agreements in the Securities or this Indenture (other than those
     referred to in clause (1), (2), (3) or (4) above) and such failure
     continues for 60 days after the notice specified below;

          (6)  Indebtedness of Parent (so long as the Existing Contingent Notes
     have not been satisfied in full and cash remains in the Contingent Note
     Reserve), the Company, any Subsidiary Guarantor or any Significant
     Subsidiary is not paid within any applicable grace period after final
     maturity or is accelerated by the holders thereof because of a default and
     the total amount of such Indebtedness unpaid or accelerated exceeds $10.0
     million;

          (7)  Parent (so long as the Existing Contingent Notes have not been
     satisfied in full and cash remains

<Page>
                                                                              70

     in the Contingent Note Reserve), the Company or any Significant Subsidiary
     pursuant to or within the meaning of any Bankruptcy Law:

               (A)    commences a voluntary case;

               (B)    consents to the entry of an order for relief against it in
          an involuntary case;

               (C)    consents to the appointment of a Custodian of it or for
          any substantial part of its property; or

               (D)    makes a general assignment for the benefit of its
          creditors;

     or takes any comparable action under any foreign laws relating to
     insolvency;

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

               (A)    is for relief against Parent (so long as the Existing
          Contingent Notes have not been satisfied in full and cash remains in
          the Contingent Note Reserve), the Company or any Significant
          Subsidiary in an involuntary case;

               (B)    appoints a Custodian of Parent (so long as the Existing
          Contingent Notes have not been satisfied in full and cash remains in
          the Contingent Note Reserve), the Company or any Significant
          Subsidiary or for any substantial part of its property; or

               (C)    orders the winding up or liquidation of Parent (so long as
          the Existing Contingent Notes have not been satisfied in full and cash
          remains in the Contingent Note Reserve), the Company or any
          Significant Subsidiary;

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

          (9)  any judgment or decree for the payment of money in excess of
     $10.0 million is entered against Parent (so long as the Existing Contingent
     Notes have not been satisfied in full and cash remains in the Contingent
     Note Reserve), the Company or any Significant Subsidiary, remains
     outstanding for a

<Page>
                                                                              71

     period of 60 consecutive days following the entry of such judgment or
     decree and is not discharged, waived or the execution thereof stayed; or

          (10) any Subsidiary Guaranty ceases to be in full force and effect
     (other than in accordance with the terms of such Subsidiary Guaranty or, in
     the case of a Subsidiary Guarantor that is not a Significant Subsidiary,
     other than as a result of bankruptcy) or any Subsidiary Guarantor denies or
     disaffirms its obligations under its Subsidiary Guaranty, as the case may
     be.

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

          The term "Bankruptcy Law" means Title 11, UNITED STATES CODE, or any
similar Federal or state law for the relief of debtors. The term "Custodian"
means any receiver, trustee, assignee, liquidator, custodian or similar official
under any Bankruptcy Law.

          A Default under clause (4) or (5) is not an Event of Default until the
Trustee or the holders of at least 25% 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 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 the
occurrence thereof, written notice in the form of an Officers' Certificate of
any Event of Default under clause (6) or (10) and any event which with the
giving of notice or the lapse of time would become an Event of Default under
clause (4) or (5) its status and what action the Company is taking or proposes
to take with respect thereto.

          SECTION 6.02.  ACCELERATION. If an Event of Default (other than an
Event of Default specified in Section 6.01(7) or (8) with respect to the
Company) occurs and is continuing, the Trustee by notice to the Company, or the
Holders of at least 25% in principal amount of the Securities by notice to the
Company and the Trustee, may declare the principal of and accrued but unpaid
interest on

<Page>
                                                                              72

all the Securities to be due and payable. Upon such a declaration, such
principal and interest shall be due and payable immediately, PROVIDED that if
any Designated Senior Indebtedness is outstanding at such time, neither the
Company nor any Subsidiary Guarantor shall make any payment with respect to the
Securities until five Business Days after the Representatives of all the issues
of Designated Senior Indebtedness receive written notice of such acceleration
and, thereafter, any such payment shall be made only if the provisions of
Article 10 and 12 do not restrict payment at such time. If an Event of Default
specified in Section 6.01(7) or (8) with respect to the Company occurs, the
principal of and interest on all the Securities shall IPSO FACTO become and be
immediately due and payable without any declaration or other act on the part of
the Trustee or any Securityholders. The Holders of a majority in principal
amount of the Securities by notice to the Trustee may rescind an acceleration
and its consequences if the rescission would not conflict with any judgment or
decree and if all existing Events of Default have been cured or waived except
nonpayment of principal or interest that has become due solely because of
acceleration. No such rescission shall affect any subsequent Default or impair
any right consequent thereto.

          SECTION 6.03.  OTHER REMEDIES. If an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy to collect the payment
of principal of or interest on the 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 6.04.  WAIVER OF PAST DEFAULTS. The Holders of a majority in
principal amount of the Securities by notice to the Trustee may waive an
existing Default and its consequences except (i) a Default in the payment of the
principal of or interest on a Security, (ii) a Default arising from the failure
to redeem or purchase any Security when required pursuant to this Indenture or
(iii) a Default in respect of a provision that under Section 9.02 cannot be
amended without the consent of each Securityholder affected. When a Default is
waived, it is deemed cured, but no such

<Page>
                                                                              73

waiver shall extend to any subsequent or other Default or impair any consequent
right.

          SECTION 6.05.  CONTROL BY MAJORITY. The Holders of a majority in
principal amount of the 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 or this Indenture or,
subject to Section 7.01, 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
from such Holders satisfactory to it in its sole discretion against all losses
and expenses caused by taking or not taking such action.

          SECTION 6.06.  LIMITATION ON SUITS. Except to enforce the right to
receive payment of principal, premium (if any) or interest when due, no
Securityholder may pursue any remedy with respect to this Indenture or the
Securities unless:

          (1)  the Holder gives to the Trustee written notice stating that an
     Event of Default is continuing;

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

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

          (4)  the Trustee does not comply with the 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 do not give the Trustee a direction inconsistent with the
     request during 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.

                                                                              74

          SECTION 6.07.  RIGHTS OF HOLDERS TO RECEIVE PAYMENT. Notwithstanding
any other provision of this Indenture, the right of any Holder to receive
payment of principal of and interest on the 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 6.08.  COLLECTION SUIT BY TRUSTEE. If an Event of Default
specified in Section 6.01(1) or (2) occurs and is continuing, the Trustee may
recover judgment in its own name and as trustee of an express trust against the
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
7.07.

          SECTION 6.09.  TRUSTEE MAY FILE PROOFS OF CLAIM. The Trustee may file
such proofs of claim and other papers or documents as may be necessary or
advisable in order to have the claims of the Trustee and the Securityholders
allowed in any judicial proceedings relative to the Company, its creditors or
its property 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 such judicial
proceeding is hereby authorized by each Holder to make payments to the Trustee
and, in the event that the Trustee shall consent to the making of such payments
directly to the Holders, to pay to the Trustee any amount due it for the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and its counsel, and any other amounts due the Trustee under Section
7.07.

          SECTION 6.10.  PRIORITIES. If the Trustee collects any money or
property pursuant to this Article 6, it shall pay out the money or property in
the following order:

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

          SECOND: to holders of Senior Indebtedness of the Company and the
     Subsidiary Guarantors, to the extent required by Articles 10 and 12;

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

<Page>
                                                                              75

     Securities for principal and interest, respectively; and

          FOURTH: to the Company.

          The Trustee may fix a record date and payment date for any payment to
Securityholders pursuant to this Section 6.10. 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 6.11 does not apply to a suit by the
Trustee, a suit by a Holder pursuant to Section 6.07 or a suit by Holders of
more than 10% in principal amount of the Securities.

          SECTION 6.12.  WAIVER OF STAY OR EXTENSION LAWS. The Company (to the
extent it may lawfully do so) shall not at any time insist upon, or plead, or in
any manner whatsoever claim or take the benefit or advantage of, any stay or
extension law wherever enacted, now or at any time hereafter in force, which may
affect the covenants or the performance of this Indenture; and the Company (to
the extent that it may lawfully do so) hereby expressly waives all benefit or
advantage of any such law, and shall not hinder, delay or impede the execution
of any power herein granted to the Trustee, but shall suffer and permit the
execution of every such power as though no such law had been enacted.

                                    ARTICLE 7

                                     TRUSTEE

          SECTION 7.01.  DUTIES OF TRUSTEE.

          (a)  If an Event of Default has occurred and is continuing, the
Trustee shall exercise the rights and powers vested in it by this Indenture and
use the same degree of care and skill in their exercise as a prudent Person
would

<Page>
                                                                              76

exercise or use under the circumstances in the conduct of such Person's own
affairs.

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

          (1)  the Trustee undertakes to perform such duties and only such
     duties as are specifically set forth in this Indenture and 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 or opinions furnished to
     the Trustee and conforming to the requirements of this Indenture. However,
     the Trustee shall examine the certificates and opinions to determine
     whether or not they conform to the requirements of this Indenture.

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

          (1)  this paragraph does not limit the effect of Section 7.01(b);

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

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

          (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 7.01.

          (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.

                                                                              77

          (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 7.01 and to the provisions of the TIA.

          SECTION 7.02.  RIGHTS OF TRUSTEE.

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

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

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

          (d)  The Trustee shall not be liable for any action it takes or omits
to take in good faith which it believes to be authorized or within its rights or
powers; PROVIDED, HOWEVER, that, without limiting the effect of Section 7.01(b),
the Trustee's conduct does not constitute wilful misconduct or negligence.

          (e)  The Trustee may consult with counsel, 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 to any action taken, omitted or suffered by it hereunder in
good faith and in accordance with the advice or opinion of such counsel.

          (f)  Except with respect to Section 4.01, the Trustee shall have no
duty to inquire as to the performance of the Company with respect to the
covenants contained in Article 4. In addition, the Trustee shall not be deemed
to have knowledge of an Event of Default except (i) any Default or Event of
Default occurring pursuant to Sections 4.01,

<Page>
                                                                              78

6.01(1) or 6.02(2) or (ii) any Default or Event of Default of which the Trustee
shall have received written notification or obtained actually knowledge.

          (g)  Delivery of reports, information and documents to the Trustee
under Section 4.02 is for informational purposes only and the Trustee's receipt
of the foregoing shall not constitute constructive notice of any information
contained therein or determinable from information contained therein, including
the Company's compliance with any of their covenants hereunder (as to which the
Trustee is entitled to rely exclusively on Officers' Certificates).

          SECTION 7.03.  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 or Registrar may do the
same with like rights. However, the Trustee must comply with Sections 7.10 and
7.11.

          SECTION 7.04.  TRUSTEE'S DISCLAIMER. The Trustee shall not be
responsible for and makes no representation, warranty or certification as to the
validity or adequacy of this Indenture or the Securities except as contained in
the Trustee's certificate of authentication. The Trustee shall not be
accountable for the Company's use of the proceeds from the issuance and sale of
the Securities and shall not be responsible for any statement of the Company,
any initial purchaser or placement agent or any other Person made in connection
with the issuance and sale of the Securities, whether oral or written and
whether contained in this Indenture, any offering document or any other
document, certificate or instrument.

          SECTION 7.05.  NOTICE OF DEFAULTS. If a Default occurs and is
continuing and if it is known to the Trustee, the Trustee shall mail to each
Securityholder notice of the Default within 90 days after it occurs. Except in
the case of a Default in payment of principal of or interest on any Security,
the Trustee may withhold the notice if and so long as a committee of its Trust
Officers in good faith determines that withholding the notice is in the
interests of Securityholders.

          SECTION 7.06.  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 for so long as
the Securities are outstanding, the Trustee shall mail to each

<Page>
                                                                              79

Securityholder a brief report dated as of May 15 that complies with TIA Section
313(a). The Trustee also shall comply with TIA $ 313(b). The Trustee will also
transmit by mail all reports required by TIA $ 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 in accordance with TIA Section 313(d). The Company agrees
to notify promptly the Trustee whenever the Securities become listed on any
stock exchange and of any delisting thereof.

          SECTION 7.07.  COMPENSATION AND INDEMNITY. The Company shall pay to
the Trustee from time to time such reasonable compensation as agreed to between
the Company and the Trustee for its acceptance of the responsibilities under
this Indenture. 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 disbursements, advancements and expenses
incurred or made by it, including costs of collection, in addition to the
compensation for its services except any such expense as may arise from its
negligence, willful misconduct or bad faith. 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 or expense (including reasonable
attorneys' fees) incurred by it in connection with the administration of this
trust and the performance of its duties hereunder. 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 may
have separate counsel and the Company shall pay the reasonable fees and expenses
of such counsel; PROVIDED, HOWEVER, the Company should not be required to pay
such fees and expenses if it assumes the Trustee's defense, and, in the
Trustee's reasonable judgment, there is no conflict of interest between the
Company and the Trustee in connection with such defense. The Company need not
pay for any settlement made without its consent, which consent shall not be
unreasonably withheld or delayed, nor reimburse any expense nor indemnify
against any loss, liability or expense incurred by the Trustee through the
Trustee's own wilful misconduct, negligence or bad faith.

          To secure the Company's payment obligations in this Section 7.07, the
Trustee shall have a lien prior to the Securities on all money or property held
or collected by

<Page>
                                                                              80

the Trustee other than money or property held in trust to pay principal of and
interest on particular Securities. Such lien shall survive the satisfaction and
discharge of this Indenture.

          The Company's payment obligations pursuant to this Section 7.07 shall
survive the resignation and removal of the Trustee and the discharge of this
Indenture. When the Trustee incurs expenses after the occurrence of a Default
specified in Section 6.01(7) or (8) with respect to the Company, the expenses
are intended to constitute expenses of administration under the Bankruptcy Law.

          The Trustee will comply with the provisions of TIA Section 313(b)(2)
to the extent applicable.

          SECTION 7.08.  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 or an order for
     relief is entered with respect to any Bankruptcy Law;

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

          (4)  the Trustee otherwise becomes incapable of acting.

          If the Trustee resigns, is removed by the 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 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

<Page>
                                                                              81

by it as Trustee to the successor Trustee, subject to the lien provided for in
Section 7.07.

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

          If the Trustee fails to comply with Section 7.10, any Securityholder
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 7.08, the Company's obligations under Section 7.07 shall continue for
the benefit of the retiring Trustee.

          SECTION 7.09.  SUCCESSOR TRUSTEE BY MERGER. If the Trustee
consolidates with, merges or converts into, or transfers all or substantially
all its corporate trust business or assets to, another corporation or banking
association, the resulting, surviving or transferee corporation without any
further act shall be the successor Trustee.

          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 $50,000,000 as set forth in its most
recent published annual report of condition. The Trustee shall comply with TIA
Section 310 (b); PROVIDED, HOWEVER, that there shall be excluded from the
operation of TIA Section 310(b)(1) any indenture or indentures under which other
securities or certificates of interest or participation in

<Page>
                                                                              82

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.

                                    ARTICLE 8

                       DISCHARGE OF INDENTURE; DEFEASANCE

          SECTION 8.01.  DISCHARGE OF LIABILITY ON SECURITIES; DEFEASANCE.

          (a)  When (l) the Company delivers to the Trustee all outstanding
Securities (other than Securities replaced pursuant to Section 2.07) for
cancellation or (2) all outstanding Securities have become due and payable,
whether at maturity or on a redemption date as a result of the mailing of a
notice of redemption pursuant to Article 3 hereof and the Company irrevocably
deposits with the Trustee funds sufficient to pay at maturity or upon redemption
all outstanding Securities, including interest thereon to maturity or such
redemption date (other than Securities replaced pursuant to Section 2.07), and
if in either case the Company pays all other sums payable hereunder by the
Company, then this Indenture shall, subject to Section 8.01(c), cease to be of
further effect. 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 and at the cost and expense of the Company.

          (b)  Subject to Sections 8.01(c) and 8.02, the Company at any time may
terminate (1) all its obligations under the Securities and this Indenture
("legal defeasance option") or (2) its obligations under Sections 4.02, 4.03,
4.04, 4.05, 4.06, 4.07, 4.08, 4.09, 4.10, 4.11 and 4.12 and the operation of
Sections 6.01(4), 6.01(6), 6.01(7), 6.01(8) and 6.01(9) (but, in the case of
Sections 6.01(7) and (8), with respect only to Parent, Subsidiary Guarantors and
Significant Subsidiaries) and the limitations contained in Sections 5.01(a)(3)
("covenant defeasance option"). The Company may exercise its legal defeasance
option notwithstanding its prior exercise of its covenant defeasance option.

<Page>
                                                                              83

          If the Company exercises its legal defeasance option, payment of the
Securities may not be accelerated because of an Event of Default with respect
thereto. 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 6.01(4), 6.01(6), 6.01(7), 6,01(8) and 6.01(9) (but, in the case of
Sections 6.01 (7) and (8), with respect only to Parent, Subsidiary Guarantors
and Significant Subsidiaries) or because of the failure of the Company to comply
with Section 5.01(a)(3). If the Company exercises its legal defeasance option or
its covenant defeasance option, each Subsidiary Guarantor, if any, shall be
released from all its obligations with respect to its Subsidiary Guaranty
simultaneously with the exercise of either such option.

          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 clauses (a) and (b) above, the Company's
obligations in Sections 2.03, 2.04, 2.05, 2.06, 2,07, 2.08, 7.07 and 7.08 and in
this Article 8 shall survive until the Securities have been paid in full.
Thereafter, the Company's obligations in Sections 7.07, 8.04 and 8.05 shall
survive.

          SECTION 8.02.  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 money
     or U.S. Government Obligations for the payment of principal of 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)  123 days pass after the deposit is made and during the 123-day
     period no Default specified in

<Page>
                                                                              84

          Sections 6.01(7) or (8) with respect to the Company occurs which is
          continuing at the end of the period;

          (4)  the deposit does not constitute a default under any other
     agreement binding on the Company and is not prohibited by Article 10 or 12;

          (5)  in the case of the legal defeasance option, the Company shall
     have delivered to the Trustee an Opinion of Counsel stating that (A) the
     Company has received from, or there has been published by, the Internal
     Revenue Service a ruling or (B) since the date 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 defeasance had not
     occurred;

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

          (7)  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 as contemplated by this Article
     8 have been complied with.

          Before or after a deposit, the Company may make arrangements
satisfactory to the Trustee for the redemption of Securities at a future date in
accordance with Article 3.

          SECTION 8.03.  APPLICATION OF TRUST MONEY. The Trustee shall hold in
trust money or U.S. Government Obligations deposited with it pursuant to (and in
accordance with the provisions of) this Article 8. 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. Money and securities so held in trust are not
subject to Article 10.

<Page>
                                                                              85

          SECTION 8.04,  REPAYMENT TO COMPANY. The Trustee and the Paying Agent
shall promptly turn over to the Company upon request any excess money or
securities held by them at any time.

          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 or interest that remains unclaimed for two years, and,
thereafter, Securityholders entitled to the money must look to the Company for
payment as general creditors.

          SECTION 8.05.  INDEMNITY FOR 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 8.06.  REINSTATEMENT. If the Trustee or Paying Agent is unable
to apply any money or U.S. Government Obligations in accordance with this
Article 8 by reason of any legal proceeding or by reason of any order or
judgment of any court or governmental authority enjoining, restraining or
otherwise prohibiting such application, the Company's obligations under this
Indenture and the Securities shall be revived and reinstated as though no
deposit had occurred pursuant to this Article 8 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 8; 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 9

                                   AMENDMENTS

          SECTION 9.01.  WITHOUT CONSENT OF HOLDERS. Parent, the Company, the
Subsidiary Guarantors and the Trustee may amend this Indenture or the Securities
without notice to or consent of any Securityholder:

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

<Page>
                                                                              86

          (2)  to comply with Article 5;

          (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, including any
     Subsidiary Guaranties, or to secure the Securities;

          (5)  to add to the covenants of the Company for the benefit of the
     Holders or to surrender any right or power herein conferred upon the
     Company, Parent or a Subsidiary Guarantor;

          (6)  to comply with any requirements of the SEC in connection with
     qualifying, or maintaining the qualification of, this Indenture under the
     TIA; or

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

          An amendment under this Section 9.01 may not make any change that
adversely affects the rights under Article 10 or 12 of any holder of Senior
Indebtedness of the Company or a Subsidiary Guarantor 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 9.01 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 9.01.

          SECTION 9.02.  WITH CONSENT OF HOLDERS. The Company, the Subsidiary
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 consents obtained in connection with a tender offer or exchange for
the Securities). However, without the consent of each Securityholder affected
thereby, an amendment may not:

<Page>
                                                                              87

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

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

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

          (4)  change the provisions applicable to the redemption of any
     Security contained in Article 3 or paragraphs 5 or 6 of the Securities;

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

          (6)  impair the right of any Securityholder to receive payment of
     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 changes in the ranking or priority of any Security that
     would adversely affect the Securityholders;

          (8)  make any change in Section 6.04 or 6.07 or the second sentence of
     this Section 9.02; or

          (9)  make any change in, or release other than in accordance with
     Section 11.06 or 8.01(b), any Subsidiary Guaranty that would adversely
     affect the Securityholders.

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

          An amendment under this Section 9.02 may not make any change that
adversely affects the rights under Article 10 or 12 of any holder of Senior
Indebtedness of the Company or of a Subsidiary Guarantor 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 9.02 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

                                                                              88

therein, shall not impair or affect the validity of an amendment under this
Section 9.02.

          SECTION 9.03.  COMPLIANCE WITH TIA. Every amendment to this Indenture
or the Securities shall comply with the TIA as then in effect.

          SECTION 9.04.  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 becomes effective upon the execution of such amendment or
waiver by the Trustee.

          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 be valid or effective for more than 120
days after such record date.

          SECTION 9.05.  NOTATION ON OR EXCHANGE OF SECURITIES. If an amendment
or waiver 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 9.06.  TRUSTEE TO SIGN AMENDMENTS. The Trustee shall sign any
amendment authorized pursuant to this

<Page>
                                                                              89

Article 9 if the amendment does not adversely affect the rights, duties,
liabilities or immunities of the Trustee. If it does, the Trustee may but need
not sign it. In signing such amendment the Trustee shall be entitled to receive
indemnity reasonably satisfactory to it and to receive, and (subject to Section
7.01) shall be fully protected in relying upon, an Officers' Certificate and an
Opinion of Counsel stating that such amendment is authorized or permitted by
this Indenture.

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

                                   ARTICLE 10

                                  SUBORDINATION

          SECTION 10.01. AGREEMENT TO SUBORDINATE. The Company agrees, and each
Securityholder by accepting a Security agrees, that the Indebtedness and other
Obligations evidenced by the Securities is subordinated in right of payment, to
the extent and in the manner provided in this Article 10, to the prior payment
of all Obligations with respect to Senior Indebtedness of the Company (whether
outstanding on the Issue Date or thereafter incurred) and that the subordination
is for the benefit of and enforceable by the holders of such 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 of the Company shall rank senior to the
Securities in accordance with the provisions set forth herein. All provisions of
this Article 10 shall be subject to Section 10.12.

          SECTION 10.02. LIQUIDATION, DISSOLUTION, BANKRUPTCY. Upon any payment
or distribution of the assets of the Company of any kind or character, whether
in cash, property or securities, to creditors upon any total or partial
liquidation or any total or partial dissolution of the Company or in a
bankruptcy, reorganization, insolvency, receivership, winding-up, assignment for
the benefit of

<Page>
                                                                              90

creditors, marshalling of assets or similar proceeding relating to the Company
or its property, whether voluntary or involuntary:

          (1)  the holders of Senior Indebtedness of the Company shall be
     entitled to receive payment in full in cash of all Obligations with respect
     to all such Senior Indebtedness before Securityholders shall be entitled to
     receive any payment or distribution of any kind or character with respect
     to the Securities or for the acquisition of any Securities for cash,
     property or otherwise; and

          (2)  until all such Senior Indebtedness is paid in full in cash, any
     payment or distribution to which Securityholders would be entitled but for
     this Article 10 shall be made to holders of such Senior Indebtedness as
     their interests may appear, except that Securityholders may receive shares
     of stock and any debt securities that are subordinated to such Senior
     Indebtedness to at least the same extent as the Securities.

          SECTION 10.03. DEFAULT ON SENIOR INDEBTEDNESS OF THE COMPANY The
Company shall not pay (in cash, property, securities or other assets), the
principal of, interest on or other Obligations owing with respect to the
Securities or make any deposit pursuant to Section 8.01 or 8.02 and may not
purchase, redeem or otherwise retire or acquire any Securities (collectively,
"pay the Securities") if either of the following (a "Payment Default") occurs
(1) any Obligations with respect to Senior Indebtedness of the Company are not
paid in full in cash when due or (2) any other default on Senior Indebtedness of
the Company occurs and the maturity of such Senior Indebtedness is accelerated
in accordance with its terms, unless, in either case, the Payment Default has
been cured or waived and any such acceleration has been rescinded or such Senior
Indebtedness has been paid in full in cash; PROVIDED, HOWEVER, that the Company
shall be entitled to pay the Securities without regard to the foregoing if the
Company and the Trustee receive written notice approving such payment from the
Representatives of all Senior Indebtedness with respect to which the Payment
Default has occurred and is continuing.

          During the continuance of any default (other than a Payment Default)
with respect to any Designated Senior Indebtedness of the Company 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

<Page>
                                                                              91

periods, the Company shall 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 of such Designated Senior Indebtedness specifying an election to
effect a Payment Blockage Period and ending 179 days thereafter. The Payment
Blockage Period shall end earlier if such Payment Blockage Period is terminated

          (1)  by written notice to the Trustee and the Company from the Person
     or Persons who gave such Blockage Notice;

          (2)  because the default giving rise to such Blockage Notice is cured,
     waived or otherwise no longer continuing; or

          (3)  because such Designated Senior Indebtedness has been discharged
     or repaid in full in cash.

Notwithstanding the provisions described in the immediately preceding two
sentences (but subject to the provisions contained in the first sentence of this
Section 10.03), unless the holders of such Designated Senior Indebtedness giving
such Blockage Notice or the Representatives of such Designated Senior
Indebtedness shall have accelerated the maturity of the Designated Senior
Indebtedness, the Company shall be entitled to resume payments on the Securities
after termination of such Payment Blockage Period. The Securities shall not be
subject to more than one Payment Blockage Period in any consecutive 360-day
period, irrespective of the number of defaults with respect to Designated Senior
Indebtedness of the Company during such period; PROVIDED, HOWEVER, that if any
Blockage Notice within such 360-day period is given by or on behalf of any
holders of Designated Senior Indebtedness of the Company (other than the Bank
Indebtedness), the Representative of the Bank Indebtedness shall be entitled to
give another Blockage Notice within such period; PROVIDED FURTHER, HOWEVER, that
in no event shall 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, and there must be 181 days during any consecutive
360-day period during which no Payment Blockage Period is in effect.

          For purposes of this Section 10.03, no default or event of default
which existed or was continuing on the date of the commencement of any Payment
Blockage Period with respect to the Designated Senior Indebtedness of the
Company initiating such Payment Blockage Period shall be, or be

<Page>
                                                                              92

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 10.04. 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 in writing the holders of the Designated Senior
Indebtedness of the Company (or their Representatives) of the acceleration
(although the failure to give any such notice shall not affect the
subordinations of this Article 10). If any Designated Senior Indebtedness of the
Company is outstanding, neither the Company nor any Subsidiary Guarantor shall
pay the Securities until five Business Days after the Representatives of all the
issues of Designated Senior Indebtedness of the Company receive written notice
of such acceleration and, thereafter, the Company and the Subsidiary Guarantors
shall be entitled to pay the Securities (and the Securityholders may accept and
retain such payment) only if this Article 10 otherwise permits payment (and the
acceptance and retention) at that time.

          SECTION 10.05. WHEN DISTRIBUTION MUST BE PAID OVER. If a distribution
or payment is made to the Trustee or Securityholders that because of this
Article 10 should not have been made to (or received by) them, the Trustee or
Securityholders who receive the distribution or payment shall hold it in trust
for holders of Senior Indebtedness of the Company and pay it over to them or
their Representatives as their interests may appear.

          SECTION 10.06. SUBROGATION. After all Senior Indebtedness of the
Company is paid in full in cash 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 such Senior Indebtedness. A
distribution made under this Article 10 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 on such Senior Indebtedness.

          SECTION 10.07. RELATIVE RIGHTS. This Article 10 defines the relative
rights of Securityholders and holders of Senior Indebtedness of the Company.
Nothing in this Indenture shall:

<Page>
                                                                              93

          (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

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

          SECTION 10.08. SUBORDINATION MAY NOT BE IMPAIRED BY COMPANY. No right
of any holder of Senior Indebtedness of the Company 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 its failure to comply with this Indenture.

          Without in any way limiting the generality of the foregoing paragraph,
the holders of Senior Indebtedness of the Company may, at any time and from time
to time, without the consent of or notice to the Trustee or the Securityholders,
without incurring responsibility to the Trustee or the Securityholders and
without impairing or releasing the subordination provided in this Article 10 or
the obligations hereunder of the Trustee and the Securityholders to the holders
of such Senior Indebtedness, do any one or more of the following: (1) change the
manner, place, terms or time of payment or extend the time of payment of, or
renew or alter, such Senior Indebtedness or any instrument evidencing the same
or any agreement under which such Senior Indebtedness is outstanding; (2) sell,
exchange, impair, release or otherwise deal with any property pledged, mortgaged
or otherwise securing such Senior Indebtedness; (3) release any Person liable in
any manner for the collection or payment of such Senior Indebtedness; and (4)
exercise or refrain from exercising any rights against the Company or any other
Person.

          SECTION 10.09. RIGHTS OF TRUSTEE AND PAYING AGENT. Notwithstanding
Section 10.03. the Trustee or Paying Agent shall continue to make payments on
the Securities and shall not be charged with knowledge of the existence of facts
that under this Article 10 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 satisfactory to it that such
payments are prohibited by this Article 10. The Company, the Registrar or
co-registrar, the Paying Agent, a Representative or a holder of Senior
Indebtedness of the

<Page>
                                                                              94

Company shall be entitled to give the notice; PROVIDED, HOWEVER, that, if an
issue of Senior Indebtedness of the Company has a Representative, only the
Representative shall be entitled to give the notice.

          The Trustee in its individual or any other capacity shall be entitled
to hold Senior Indebtedness of the Company with the same rights it would have if
it were not Trustee. The Registrar and Co-registrar and the Paying Agent shall
be entitled to do the same with like rights. The Trustee shall be entitled to
all the rights set forth in this Article 10 with respect to any Senior
Indebtedness of the Company which may at any time be held by it, to the same
extent as any other holder of such Senior Indebtedness; and nothing in Article 7
shall deprive the Trustee of any of its rights as such holder. Nothing in this
Article 10 shall apply to claims of, or payments to, the Trustee (in its
capacity as such) under or pursuant to Section 7.07.

          SECTION 10.10. DISTRIBUTION OR NOTICE TO REPRESENTATIVE. Whenever any
Person is to make a distribution or give a notice to holders of Senior
indebtedness of the Company, such Person shall be entitled to make such
distribution or give such notice to their Representative (if any).

          SECTION 10.11. ARTICLE 10 NOT TO PREVENT EVENTS OF DEFAULT OR LIMIT
RIGHT TO ACCELERATE. The failure to make a payment pursuant to the Securities by
reason of any provision in this Article 10 shall not be construed as preventing
the occurrence of a Default. Nothing in this Article 10 shall have any effect on
the right of the Securityholders or the Trustee to accelerate the maturity of
the Securities in accordance with Section 6.02.

          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 in accordance with Article 8 by the Trustee
for the payment of principal of and interest on the Securities shall not be
subordinated to the prior payment of any Senior Indebtedness of the Company or
subject to the restrictions set forth in this Article 10, and none of the
Securityholders shall be obligated to pay over any such amount to the Company or
any holder of Senior Indebtedness of the Company or any other creditor of the
Company.

          SECTION 10.13. TRUSTEE ENTITLED TO RELY. Upon any payment or
distribution pursuant to this Article 10, the Trustee and the Securityholders
shall be entitled to rely

<Page>
                                                                              95

          (1)  upon any order or decree of a court of competent jurisdiction in
     which any proceedings of the nature referred to in Section 10.02 are
     pending,

          (2)  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

          (3)  upon the Representatives of Senior Indebtedness of the Company

for the purpose of ascertaining the Persons entitled to participate in such
payment or distribution, the holders of such 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 10.

          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 of the Company to participate in any payment or distribution
pursuant to this Article 10, the Trustee shall be entitled to request such
Person to furnish evidence to the reasonable satisfaction of the Trustee as to
the amount of such 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 10, and, if such
evidence is not furnished, the Trustee shall be entitled to defer any payment to
such Person pending judicial determination as to the right of such Person to
receive such payment. The provisions of Sections 7.01 and 7.02 shall be
applicable to all actions or omissions of actions by the Trustee pursuant to
this Article 10.

          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 of the Company as provided in this Article 10 and appoints
the Trustee as attorney-in-fact for any and all such purposes.

          SECTION 10.15. TRUSTEE MOT_FIDUCIARY FOR HOLDERS OF SENIOR
INDEBTEDNESS OF THE COMPANY. The Trustee shall not be deemed to owe any
fiduciary duty to the holders of Senior Indebtedness of the Company and shall
not be liable to any such holders if it shall mistakenly pay over or

<Page>
                                                                              96

distribute to Securityholders or the Company or any other Person, money or
assets to which any holders of Senior Indebtedness of the Company shall be
entitled by virtue of this Article 10 or otherwise.

          SECTION 10.16. RELIANCE BY HOLDERS OF SENIOR INDEBTEDNESS OF THE
COMPANY ON SUBORDINATION PROVISIONS. Each Securityholder by accepting a Security
(whether upon original issue or upon transfer, assignment or exchange thereof)
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 of the Company, whether such Senior Indebtedness was created or
acquired before or after the issuance of the Securities, to acquire and continue
to hold, or to continue to hold, such Senior Indebtedness and such holder of
such 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 11

                              SUBSIDIARY GUARANTIES

          SECTION 11.01. SUBSIDIARY GUARANTIES. Each Subsidiary Guarantor hereby
unconditionally and irrevocably guarantees, jointly and severally, to each
Holder and to the Trustee and its successors and assigns (a) the full and
punctual payment of principal of and interest on the Securities when due,
whether at maturity, by acceleration, by redemption or otherwise, and all other
monetary obligations of the Company under this Indenture and the Securities and
(b) the full and punctual performance within applicable grace periods of all
other obligations of the Company under this Indenture and the Securities (all
the foregoing being hereinafter collectively called the "Securities
Obligations"). Each Subsidiary Guarantor further agrees that the Securities
Obligations may be extended or renewed, in whole or in part, without notice or
further assent from such Subsidiary Guarantor and that such Subsidiary Guarantor
will remain bound under this Article 11 notwithstanding any extension or renewal
of any Securities Obligation.

          Each Subsidiary Guarantor waives presentation to, demand of, payment
from and protest to the Company of any of the Securities Obligations and also
waives notice of protest for nonpayment. Each Subsidiary Guarantor waives notice
of any default under the Securities or the Securities

<Page>
                                                                              97

Obligations. The obligations of each Subsidiary Guarantor hereunder shall not be
affected by

          (a)  the failure of any Holder or the Trustee to assert any claim or
     demand or to enforce any right or remedy against the Company or any other
     Person (including any Subsidiary Guarantor) under this Indenture, the
     Securities or any other agreement or otherwise;

          (b)  any extension or renewal of any such claim, demand, right or
     remedy;

          (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 Securities Obligations or any of them;

          (e)  the failure of any Holder or the Trustee to exercise any right or
     remedy against any other guarantor of the Securities Obligations; or

          (f)  except as set forth in Section 11.06, any change in the ownership
     of such Subsidiary Guarantor.

          Each Subsidiary Guarantor further agrees that its Subsidiary Guaranty
herein constitutes a guarantee of payment, performance and compliance when due
(and not a guarantee of collection) and waives any right to require that any
resort be had by any Holder or the Trustee to any security held for payment of
the Securities Obligations.

          Each Subsidiary Guaranty is, to the extent and in the manner set forth
in Article 12, subordinated and subject in right of payment to the prior payment
in full of the principal of and premium, if any, and interest on all Senior
Indebtedness of the Subsidiary Guarantor giving such Subsidiary Guaranty and
each Subsidiary Guaranty is made subject to such provisions of this Indenture.

          Except as expressly set forth in Sections 8.01(b), 11.02 and 11.06,
the obligations of each Subsidiary Guarantor hereunder shall not be subject to
any reduction, limitation, impairment or termination for any reason, including
any claim of waiver, release, surrender, alteration or compromise, and shall not
be subject to any defense of setoff, counterclaim, recoupment or termination
whatsoever or by reason of the invalidity, illegality or

<Page>
                                                                              98

unenforceability of the Securities Obligations or otherwise. Without limiting
the generality of the foregoing, the obligations of each Subsidiary Guarantor
herein shall not be discharged or impaired or otherwise affected by the failure
of any Holder or the Trustee to assert any claim or demand or to enforce any
remedy under this Indenture, the 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 such Subsidiary Guarantor or would
otherwise operate as a discharge of such Subsidiary Guarantor as a matter of law
or equity.

          Each Subsidiary Guarantor further agrees that its 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 Securities
Obligation is rescinded or must otherwise be restored by any Holder or the
Trustee 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 or the Trustee has at law or in equity against any
Subsidiary Guarantor by virtue hereof, upon the failure of the Company to pay
the principal of or interest on any Securities Obligation when and as the same
shall become due, whether at maturity, by acceleration, by redemption or
otherwise, or to perform or comply with any other Securities Obligation, each
Subsidiary Guarantor hereby promises to and shall, upon receipt of written
demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the
Holders or the Trustee an amount equal to the sum of

          (1)  the unpaid amount of such Securities Obligations,

          (2)  accrued and unpaid interest on such Securities Obligations (but
     only to the extent not prohibited by law) and

          (3)  all other monetary Securities Obligations of the Company to the
     Holders and the Trustee.

          Each Subsidiary Guarantor agrees that it shall not be entitled to any
right of subrogation in respect of any Securities Obligations guaranteed hereby
until payment in full of all Securities Obligations and all obligations to which
the Securities Obligations are subordinated as

<Page>
                                                                              99

provided in Article 12. Each Subsidiary Guarantor further agrees that, as
between it, on the one hand, and the Holders and the Trustee, on the other hand,

          (x)  the maturity of the Securities Obligations Guaranteed hereby may
     be accelerated as provided in Article 6 for the purposes of such Subsidiary
     Guarantor's Subsidiary Guaranty herein, notwithstanding any stay,
     injunction or other prohibition preventing such acceleration in respect of
     the Securities Obligations guaranteed hereby, and

          (y)  in the event of any declaration of acceleration of such
     Securities Obligations as provided in Article 6, such Securities
     Obligations (whether or not due and payable) shall forthwith become due and
     payable by such Subsidiary Guarantor for the purposes of this Section
     11.01.

          Each Subsidiary Guarantor also agrees to pay any and all costs and
expenses (including reasonable attorneys' fees) incurred by the Trustee or any
Holder in enforcing any rights under this Section 11.01.

          SECTION 11.02. LIMITATION ON LIABILITY. Any term or provision of this
Indenture to the contrary notwithstanding, the maximum aggregate amount of the
Securities Obligations guaranteed hereunder by any Subsidiary Guarantor shall
not exceed the maximum amount that can be hereby guaranteed without rendering
this Indenture, as it relates to such Subsidiary Guarantor, voidable under
applicable law relating to fraudulent conveyance or fraudulent transfer or
similar laws affecting the rights of creditors generally.

          SECTION 11.03. SUCCESSORS AND ASSIGNS. This Article 11 shall be
binding upon each Subsidiary Guarantor and its successors and assigns and shall
enure to the benefit of the successors and assigns of the Trustee and the
Holders and, in the event of any transfer or assignment of rights by any Holder
or the Trustee, the rights and privileges conferred upon that party in this
Indenture and in the Securities shall automatically extend to and be vested in
such transferee or assignee, all subject to the terms and conditions of this
Indenture.

          SECTION 11.04. NO WAIVER. Neither a failure nor a delay on the part of
either the Trustee or the Holders in exercising any right, power or privilege
under this Article 11 shall operate as a waiver thereof, nor shall a single or
partial exercise thereof preclude any other or

<Page>
                                                                             100

further exercise of any right, power or privilege. The rights, remedies and
benefits of the Trustee and the Holders herein expressly specified are
cumulative and not exclusive of any other rights, remedies or benefits which
either may have under this Article 11 at law, in equity, by statute or
otherwise.

          SECTION 11.05. MODIFICATION. No modification, amendment or waiver of
any provision of this Article 11, nor the consent to any departure by any
Subsidiary Guarantor therefrom, shall in any event be effective unless the same
shall be in writing and signed by the Trustee, and then such waiver or consent
shall be effective only in the specific instance and for the purpose for which
given. No notice to or demand on any Subsidiary Guarantor in any case shall
entitle such Subsidiary Guarantor to any other or further notice or demand in
the same, similar or other circumstances.

          SECTION 11.06. RELEASE OF SUBSIDIARY GUARANTOR. Upon

          (i)    the sale (including any sale pursuant to any exercise of
     remedies by a holder of Senior Indebtedness of the Company or of such
     Subsidiary Guarantor) or other disposition (including by way of
     consolidation or merger) of a Subsidiary Guarantor,

          (ii)   the sale or disposition of all or substantially all the assets
     of such Subsidiary Guarantor or

          (iii)  upon the designation of such Subsidiary Guarantor as an
     Unrestricted Subsidiary pursuant to the terms of this Indenture,

such Subsidiary Guarantor shall be deemed released from all obligations under
this Article 11 without any further action required on the part of the Trustee
or any Holder, in each case other than a sale or disposition to Parent or a
Subsidiary of Parent. In the case of clauses (i) and (ii) above, the Company
shall provide an Officers' Certificate to the Trustee to the effect that the
Company will comply with its obligations under Section 4.06. At the request of
the Company, the Trustee shall execute and deliver an appropriate instrument
evidencing such release.

          SECTION 11.07. CONTRIBUTION. Each Subsidiary Guarantor that makes a
payment under its Subsidiary Guaranty shall be entitled upon payment in full of
all guarantied obligations under this Indenture to a contribution from each

<Page>
                                                                             101

other Subsidiary Guarantor in an amount equal to such other Subsidiary
Guarantor's pro rata portion of such payment based on the respective net assets
of all the Subsidiary Guarantors at the time of such payment determined in
accordance with GAAP.

                                   ARTICLE 12

                     SUBORDINATION OF SUBSIDIARY GUARANTIES

          SECTION 12.01. AGREEMENT TO SUBORDINATE. Each Subsidiary Guarantor
agrees, and each Securityholder by accepting a Security agrees, that the
Indebtedness evidenced by such Subsidiary Guarantor's Subsidiary Guaranty is
subordinated in right of payment, to the extent and in the manner provided in
this Article 12, to the prior payment of all Senior Indebtedness of such
Subsidiary Guarantor (whether outstanding on the Issue Date or thereafter
incurred) and that the subordination is for the benefit of and enforceable by
the holders of such Senior Indebtedness. The Securities Obligations of a
Subsidiary Guarantor shall in all respects rank PARI PASSU with all other Senior
Subordinated Indebtedness of such Subsidiary Guarantor and only Senior
Indebtedness of such Subsidiary Guarantor (including such Subsidiary Guarantor's
Guarantee of Senior Indebtedness of the Company) shall rank senior to the
Securities Obligations of such Subsidiary Guarantor in accordance with the
provisions set forth herein.

          SECTION 12.02. LIQUIDATION, DISSOLUTION. BANKRUPTCY. Upon any payment
or distribution of the assets of any Subsidiary Guarantor of any kind or
character, whether in cash, property or securities, to creditors upon a total or
partial liquidation or a total or partial dissolution of such Subsidiary
Guarantor or in a bankruptcy, reorganization, insolvency, receivership,
winding-up, assignment for the benefit of creditors, marshalling of assets or
similar proceeding relating to such Subsidiary Guarantor or its property whether
voluntary or involuntary:

          (1)  the holders of Senior Indebtedness of such Subsidiary Guarantor
     shall be entitled to receive payment in full in cash of all Obligations
     with respect to all such Senior Indebtedness before Securityholders shall
     be entitled to receive any payment or distribution of any kind or character
     with respect to any Obligations of such Subsidiary Guarantor; and

          (2)  until the Senior Indebtedness of such Subsidiary Guarantor is
     paid in full in cash, any payment or distribution to which Securityholders
     would

<Page>
                                                                             102

     be entitled but for this Article 12 shall be made to holders of such Senior
     Indebtedness as their interests may appear, except that Securityholders may
     receive shares of stock and any debt securities that are subordinated to
     such Senior Indebtedness to at least the same extent as the Securities.

          SECTION 12.03. DEFAULT ON SENIOR INDEBTEDNESS OF SUBSIDIARY GUARANTOR.
No Subsidiary Guarantor shall make any payment (in cash, property, securities or
other assets) with respect to its Subsidiary Guaranty or purchase, redeem or
otherwise retire, acquire or defease any Securities or other Securities
Obligations (collectively, "pay its Subsidiary Guaranty") if either of the
following (a "Payment Default") occurs (1) any Senior Indebtedness of such
Subsidiary Guarantor is not paid in full in cash when due or (2) any other
default on Senior Indebtedness of such Subsidiary Guarantor occurs and the
maturity of such Senior Indebtedness is accelerated in accordance with its
terms, unless, in either case, the Payment Default has been cured or waived and
any such acceleration has been rescinded or such Senior Indebtedness has been
paid in full in cash; PROVIDED, HOWEVER, that any Subsidiary Guarantor shall be
entitled to make any payment with respect to its Subsidiary Guaranty without
regard to the foregoing if such Subsidiary Guarantor and the Trustee receive
written notice approving such payment from the Representatives of all Senior
Indebtedness with respect to which the Payment Default has occurred and is
continuing.

          During the continuance of any default (other than a Payment Default)
with respect to any Designated Senior Indebtedness of such Subsidiary Guarantor
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, such Subsidiary
Guarantor shall not pay its Subsidiary Guaranty 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 of such Designated Senior Indebtedness specifying an election to
effect a Payment Blockage Period and ending 179 days thereafter. The Payment
Blockage Period shall end earlier if such Payment Blockage Period is terminated

          (1)  by written notice to the Trustee and such Subsidiary Guarantor
     from the Person or Persons who gave such Blockage Notice;

<Page>
                                                                             103

          (2)  because the default giving rise to such Blockage Notice is cured,
     waived or otherwise no longer continuing; or

          (3)  because such Designated Senior indebtedness has been discharged
     or repaid in full in cash.

Notwithstanding the provisions described in the immediately preceding two
sentences (but subject to the provisions contained in the first sentence of this
Section 12.03), unless the holders of such Designated Senior Indebtedness giving
such Blockage Notice or the Representatives of such Designated Senior
Indebtedness shall have accelerated the maturity of such Designated Senior
indebtedness, any Subsidiary Guarantor shall be entitled to resume payments
pursuant to its Subsidiary Guaranty after termination of such Payment Blockage
Period. No Subsidiary Guaranty shall be subject to more than one Blockage Period
in any consecutive 360-day period, irrespective of the number of defaults with
respect to Designated Senior Indebtedness of such Subsidiary Guarantor during
such period; PROVIDED, HOWEVER, that if any Blockage Notice within such 360-day
period is given by or on behalf of any holders of Designated Senior Indebtedness
of such Subsidiary Guarantor (other than the Bank Indebtedness), the
Representative of the Bank Indebtedness shall be entitled to give another
Blockage Notice within such period; PROVIDED FURTHER, HOWEVER, that in no event
shall 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, and there must be 181 days during any consecutive 360-day period
during which no Payment Blockage Period is in effect.

          For purposes of this Section 12.03, no default or event of default
which existed or was continuing on the date of the commencement of any Payment
Blockage Period with respect to the Designated Senior Indebtedness of such
Subsidiary Guarantor 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 12.04. DEMAND FOR PAYMENT. If a demand for payment is made on
a Subsidiary Guarantor pursuant to Article 11, the Trustee shall promptly notify
in writing the holders of the Designated Senior Indebtedness of such Subsidiary
Guarantor (or their Representatives) of such demand.

<Page>
                                                                             104

          SECTION 12.05. WHEN DISTRIBUTION MUST BE PAID OVER. If a distribution
is made to the Trustee as the Securityholders that because of this Article 12
should not have been made to (or received by) them, the Trustee or the
Securityholders who receive the distribution or payment shall hold it in trust
for holders of Senior Indebtedness of the applicable Subsidiary Guarantor and
pay it over to them or their Representatives as their interests may appear.

          SECTION 12.06. SUBROGATION. After all Senior Indebtedness of a
Subsidiary Guarantor is paid in full in cash 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 of such
Subsidiary Guarantor. A distribution made under this Article 12 to holders of
Senior Indebtedness which otherwise would have been made to Securityholders is
not, as between the relevant Subsidiary Guarantor and Securityholders, a payment
by such Subsidiary Guarantor on such Senior Indebtedness.

          SECTION 12.07. RELATIVE RIGHTS. This Article 12 defines the relative
rights of Securityholders and holders of Senior Indebtedness of a Subsidiary
Guarantor. Nothing in this Indenture shall:

          (1)  impair, as between a Subsidiary Guarantor and Securityholders,
     the obligation of such Subsidiary Guarantor, which is absolute and
     unconditional, to pay its Subsidiary Guaranty to the extent set forth in
     Article 11; or

          (2)  prevent the Trustee or any Securityholder from exercising its
     available remedies upon a default by such Subsidiary Guarantor under its
     Subsidiary Guaranty, subject to the rights of holders of Senior
     Indebtedness of such Subsidiary Guarantor to receive distributions
     otherwise payable to Securityholders.

          SECTION 12.08. SUBORDINATION MAY NOT BE IMPAIRED BY THE SUBSIDIARY
GUARANTORS. No right of any holder of Senior Indebtedness of any Subsidiary
Guarantor to enforce the subordination of the Subsidiary Guaranty of such
Subsidiary Guarantor shall be impaired by any act or failure to act by such
Subsidiary Guarantor or by such Subsidiary Guarantor's failure to comply with
this Indenture.

          Without in any way limiting the generality of the foregoing paragraph,
the holders of Senior Indebtedness of a Subsidiary Guarantor may, at any time
and from time to time, without the consent of or notice to the Trustee or the

<Page>
                                                                             105

Securityholders, without incurring responsibility to the Trustee or the
Securityholders and without impairing or releasing the subordination provided in
this Article 12 or the obligations hereunder of the Trustee and the
Securityholders to the holders of such Senior Indebtedness, do any one or more
of the following: (1) change the manner, place, terms or time of payment or
extend the time of payment of, or renew or alter, such Senior Indebtedness or
any instrument evidencing the same or any agreement under which such Senior
Indebtedness is outstanding; (2) sell, exchange, impair, release or otherwise
deal with any property pledged, mortgaged or otherwise securing such Senior
Indebtedness; (3) release any Person liable in any manner for the collection or
payment of such Senior Indebtedness; and (4) exercise or refrain from exercising
any rights against such Subsidiary Guarantor or any other Person.

          SECTION 12.09. RIGHTS OF TRUSTEE AND PAYING AGENT. Notwithstanding
Section 12.03, the Trustee or Paying Agent shall continue to make payments on
any Subsidiary Guaranty and shall not be charged with knowledge of the existence
of facts under this Article 12 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 written notice satisfactory to
it that such payments are prohibited by this Article 12. The Company, the
relevant Subsidiary Guarantor, the Registrar or co-registrar, the Paying Agent,
a Representative or a holder of Senior Indebtedness of such Subsidiary Guarantor
shall be entitled to give the notice; PROVIDED, HOWEVER, that, if an issue of
Senior Indebtedness of any Subsidiary Guarantor has a Representative, only the
Representative shall be entitled to give the notice.

          The Trustee in its individual or any other capacity shall be entitled
to hold Senior Indebtedness of any Subsidiary Guarantor with the same rights it
would have if it were not the Trustee. The Registrar and co-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 12 with respect to any Senior
Indebtedness of any Subsidiary Guarantor which may at any time be held by it, to
the same extent as any other holder of such Senior Indebtedness; and nothing in
Article 7 shall deprive the Trustee of any of its rights as such holder. Nothing
in this Article 12 shall apply to claims of, or payments to, the Trustee under
or pursuant to Section 7.07.

          SECTION 12.10. DISTRIBUTION OR NOTICE TO REPRESENTATIVE. Whenever any
Person is to make a

<Page>
                                                                             106

distribution or give a notice to holders of Senior Indebtedness of any
Subsidiary Guarantor, such Person shall be entitled to make such distribution or
give such notice to their Representative (if any).

          SECTION 12.11. ARTICLE 12 NOT TO PREVENT EVENTS OF DEFAULT OR LIMIT
RIGHT TO DEMAND PAYMENT. The failure to make a payment pursuant to a Subsidiary
Guaranty by reason of any provision in this Article 12 shall not be construed as
preventing the occurrence of a Default. Nothing in this Article 12 shall have
any effect on the right of the Securityholders or the Trustee to make a demand
for payment on any Subsidiary Guarantor pursuant to its Subsidiary Guaranty.

          SECTION 12.12. TRUSTEE ENTITLED TO RELY. Upon any payment or
distribution pursuant to this Article 12, the Trustee and the Securityholders
shall be entitled to rely

          (1)  upon any order or decree of a court of competent jurisdiction in
     which any proceedings of the nature referred to in Section 12.02 are
     pending,

          (2)  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

          (3)  upon the Representatives for the holders of Senior Indebtedness
     of any Subsidiary Guarantor

for the purpose of ascertaining the Persons entitled to participate in such
payment or distribution, the holders of such Senior Indebtedness and other
Indebtedness of such Subsidiary 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 12.

          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 of any Subsidiary Guarantor to participate in any payment or
distribution pursuant to this Article 12, the Trustee shall be entitled to
request such Person to furnish evidence to the reasonable satisfaction of the
Trustee as to the amount of Senior Indebtedness of such Subsidiary Guarantor
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 12, and, if such evidence is not furnished, the
Trustee shall be entitled to defer any payment to such

<Page>
                                                                             107

Person pending judicial determination as to the right of such Person to receive
such payment. The provisions of Sections 7.01 and 7.02 shall be applicable to
all actions or omissions of actions by the Trustee pursuant to this Article 12.

          SECTION 12.13. 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 of any Subsidiary
Guarantor as provided in this Article 12 and appoints the Trustee as
attorney-in-fact for any and all such purposes.

          SECTION 12.14. TRUSTEE NOT FIDUCIARY FOR HOLDERS OF SENIOR
INDEBTEDNESS OF SUBSIDIARY GUARANTOR. The Trustee shall not be deemed to owe any
fiduciary duty to the holders of Senior Indebtedness of any Subsidiary Guarantor
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 such Senior indebtedness shall be entitled by
virtue of this Article 12 or otherwise.

          SECTION 12.15. RELIANCE BY HOLDERS OF SENIOR INDEBTEDNESS OF
SUBSIDIARY GUARANTORS 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 of any Subsidiary Guarantor, whether such
Senior Indebtedness was created or acquired before or after the issuance of the
Securities, to acquire and continue to hold, 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 13 MISCELLANEOUS

          SECTION 13.01. TIA CONTROLS. If any provision of this Indenture
limits, qualifies or conflicts with another provision which is required to be
included in this Indenture by the TIA, the required provision shall control.

require registration under the Securities Act. The Rule 144A Global Security,
the Temporary Regulation S Global Security and the Permanent Regulation S Global
Security are collectively referred to herein as "Global Securities". The

Depository.

             Members of, or participants in, the Depository ("Agent Members")
shall have no rights under this Indenture with respect to any Global Security
held on their behalf by the Depository or by the Trustee as the custodian of the

shall be entitled to treat the Depository as the absolute owner of such Global
Security for all purposes whatsoever. Notwithstanding the foregoing, nothing
herein shall prevent the Company, the Trustee or any agent of the Company or the
Trustee from giving effect to any written certification, proxy or other
authorization furnished by the Depository or impair, as between the Depository

governing the exercise of the rights of a holder of a beneficial interest in any
Global Security.

             (c) CERTIFICATED SECURITIES. Except as provided in this Section 2.1
or Section 2.3 or 2.4, owners of beneficial interests in Global Securities shall

signed by two Officers or by an Officer and either an Assistant Treasurer or an
Assistant Secretary of the Company. Such 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, in the case of any issuance of Additional
Securities pursuant to Section 2.13 of the Indenture, shall certify that such
issuance is in compliance with Section 4.03 of the Indenture.

     interests therein shall be effected through the Depository, in accordance
     with this Indenture (including applicable restrictions on transfer set
     forth herein, if any) and the procedures of the Depository therefor. A
     transferor of a beneficial interest in a Global Security shall deliver to
     the Registrar a written order given in accordance with the Depository's
     procedures containing information regarding the participant account of the
     Depository to be credited with a beneficial interest in the Global
     Security. The Registrar shall, in accordance with such instructions,
     instruct the Depository to credit to the account of the Person specified in
     such instructions a beneficial interest in the Global Security and to debit
     the account of the Person making the transfer the beneficial interest in
     the Global Security being transferred.

             (ii) If the proposed transfer is a transfer of a beneficial
     interest in one Global Security to a beneficial interest in another Global
     Security, the Registrar shall reflect on its books and records the date and
     an increase in the principal amount of the Global Security to which such
     interest is being transferred in an amount equal to the principal amount of
     the interest to be so transferred, and the Registrar shall reflect on its
     books and records the date and a corresponding decrease in the principal
     amount of the Global Security from which such interest is being
     transferred.

             (iii) Notwithstanding any other provisions of this Appendix (other
     than the provisions set forth in Section 2.4), a Global Security may not be
     transferred as a whole except by the Depository to a nominee of the
     Depository or by a nominee of the Depository to the Depository or another
     nominee of the Depository or by the Depository or any such nominee to a
     successor Depository or a nominee of such successor Depository.

             (iv) In the event that a Global Security is exchanged for
     Definitive Securities pursuant to Section 2.4 of this Appendix, prior to
     the consummation of a Registered Exchange Offer or the effectiveness of a
     Shelf Registration Statement with respect to such Securities, such
     Securities may be exchanged only in accordance with such procedures as are
     substantially consistent with the provisions of this Section 2.3

     Securities intended to ensure that such transfers comply with Rule 144A,
     Regulation S or another applicable exemption under the Securities Act, as
     the case may be) and such other procedures as may from time to time be
     adopted by the Company.

             (d) RESTRICTIONS ON TRANSFER OF TEMPORARY REGULATION S GLOBAL
SECURITIES. During the Distribution Compliance Period, beneficial ownership
interests in Temporary Regulation S Global Securities may only be sold, pledged
or transferred through Euroclear or Clearstream in accordance with the
Applicable Procedures and only (i) to the Company, (ii) so long as such Security
is eligible for resale pursuant to Rule 144A, to a Person whom the selling
holder reasonably believes is a QIB that purchases for its own account or for
the account of a QIB to whom notice is given that the resale, pledge or transfer
is being made in reliance on Rule 144A, (iii) in an offshore transaction in
accordance with Regulation S, (iv) pursuant to an exemption from registration
under the Securities Act provided by Rule 144 (if applicable) under the
Securities Act or (v) pursuant to an effective registration statement under the
Securities Act, in each case in accordance with any applicable securities laws

     shall permit the transferee thereof to exchange such Transfer Restricted
     Security for a certificated Security that does not bear the legend set

                    10 1/2% Senior Subordinated Note Due 2013

1.   INTEREST

             Amy Acquisition Corp., 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; PROVIDED, HOWEVER,
that if a Registration Default (as defined in the Registration Rights Agreement)
occurs, additional interest will accrue on this Security at a rate of 0.25% per
annum (increasing by an additional 0.25% per annum after each consecutive 90-day
period that occurs after the date on which such Registration Default occurs up
to a maximum additional interest rate of 1.00%) from and including the date on
which any such Registration Default shall occur to but excluding the date on
which all Registration Defaults have been cured. The Company will pay interest
semiannually on April 1 and October 1 of each year, commencing October 1, 2003.

             Interest on the Securities will accrue from the most recent date to
which interest has been paid or, if no interest has been paid, from March 27,
2003. Interest on overdue principal will be paid by the Issuer at 1% per annum
in excess of the rate shown above and the Issuer will pay interest on overdue
installments of interest at such higher rate 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

             The Company will pay interest on the Securities (except defaulted
interest) to the Persons who are registered holders of Securities at the close
of business on the March 15 or September 15 next preceding the interest payment
date even if Securities are canceled 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 the Securities represented by a
Global Security (including principal, premium, if any, and interest) will be
made by wire transfer of immediately available funds to the accounts specified
by The Depository Trust Company. The Company will make all payments in respect
of a certificated Security (including principal,

                                                                               2

premium, if any, and interest) by mailing a check to the registered address of
each Holder thereof; PROVIDED, HOWEVER, that payments on a certificated Security
will be made 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 30 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, U.S. Bank National Association (the "Trustee"), will act
as Paying Agent and Registrar. The Company may appoint and change any Paying
Agent or Registrar without notice. The Company or any of its domestically
incorporated Wholly Owned Subsidiaries may act as Paying Agent or Registrar.

4.   INDENTURE

             The Company issued the Securities under an Indenture dated as of
March 27, 2003 (the "Indenture"), among the Company, AmeriPath Holdings, Inc.,
the guarantors party thereto 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"). Terms defined in the
Indenture 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 obligations of the Company.
The Securities issued on the Issue Date, any Additional Securities and any
Exchange Securities or Private Exchange Securities will be treated as a single
class for all purposes under the Indenture. The Indenture contains covenants
that limit the ability of the Company and its subsidiaries to incur additional
indebtedness; pay dividends or distributions on, or redeem or repurchase capital
stock; make investments; issue or sell capital stock of subsidiaries; engage in
transactions with affiliates; transfer or sell assets; guarantee indebtedness;
change their line of business; restrict dividends or other payments of
subsidiaries; and consolidate, merge or transfer all or substantially all of its
assets and the assets of its subsidiaries. These covenants are subject to
important exceptions and qualifications.

5.   OPTIONAL REDEMPTION

             Except as set forth below, the Company shall not be entitled to
redeem the Securities.

             On and after April 1, 2008, the Company shall be entitled at its
option to redeem all or a portion of the Securities (which includes Additional
Securities, if any) upon not less than 30 nor more than 60 days' notice, at the
redemption prices (expressed in percentages of principal amount on the
redemption date), plus accrued 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 April 1 of the years set forth below:

             2008                                        105.25%
             2009                                        103.50%
             2010                                        101.75%
             2011 and thereafter                        100.000%
</Table>

             In addition, prior to April 1, 2006, the Company shall be entitled
at its option on one or more occasions to redeem Securities (which includes
Additional Securities, if any) in an aggregate principal amount not to exceed
35% of the aggregate principal amount of the Securities originally issued at a
redemption price (expressed as a percentage of principal amount) of 110.50%,
plus accrued and unpaid interest to the redemption date, with the net cash
proceeds received by the Company from one or more Qualified Equity Offerings
(PROVIDED that, if the Qualified Equity Offering is an offering by Parent, a
portion of the Net Cash Proceeds thereof equal to the amount required to redeem
any such Notes is contributed to the equity capital of the Company or used to
acquire Capital Stock of the Company (other than Disqualified Stock) from the
Company); PROVIDED, HOWEVER, that (1) at least 65% of such aggregate principal
amount of Securities (which includes Additional Securities, if any) remains
outstanding immediately after the occurrence of each such redemption (other than
Securities held, directly or indirectly, by the Company or its Affiliates); and
(2) each such redemption occurs within 90 days after the date of the related
Qualified Equity Offering.

                                                                               4

6.   NOTICE OF REDEMPTION

             Notice of redemption will be mailed at least 30 days but not more
than 60 days before the redemption date to each Holder of Securities to be
redeemed at its registered address. Securities in denominations larger than
$1,000 principal amount may be redeemed in part but only in whole multiples of
$1,000. Securities in denominations of $1,000 principal amount or less may be
redeemed in whole but not in part. If money sufficient to pay the redemption
price of and accrued interest on all Securities (or portions thereof) to be
redeemed on the redemption date is deposited with the Paying Agent on or before
the redemption date and certain other conditions are satisfied, on and after
such date interest ceases to accrue on such Securities (or such portions
thereof) called for redemption.

7.   PUT PROVISIONS

             Upon a Change of Control, any Holder of Securities will have the
right to cause the Company to repurchase all of the Securities of such Holder at
a repurchase price equal to 101% of the principal amount of the Securities to be
repurchased plus accrued interest to the date of repurchase (subject to the
right of holders of record on the relevant record date to receive interest due
on the related interest payment date) as provided in, and subject to the terms
of, the Indenture.

8.   SUBORDINATION

             The Securities are subordinated to Senior Indebtedness of the
Company, as defined in the Indenture. To the extent provided in the Indenture,
Senior Indebtedness of the Company 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 it effect and appoints the Trustee as
attorney-in-fact for such purpose.

9.   SUBSIDIARY GUARANTY

             The payment by the Company of the principal of, and premium and
interest on, the Securities is fully and unconditionally guaranteed on a joint
and several senior subordinated basis by each of the Subsidiary Guarantors to
the extent set forth in the Indenture.

                                                                               5

10.  DENOMINATIONS; TRANSFER; EXCHANGE

             The Securities are in registered form without coupons in
denominations of $1,000 principal amount and whole multiples of $1,000. A Holder
may transfer or exchange Securities in accordance with the Indenture. The
Company or the Registrar may require a Holder, among other things, to pay a sum
sufficient to pay all taxes, assessments or other governmental charges in
connection with any transfer or exchange pursuant to this Section. The Company
shall not be required to make and the Registrar need not register transfers or
exchanges of Securities selected for redemption (except, in the case of
Securities to be redeemed in part, the portion thereof not to be redeemed) or
any Securities for a period of 15 days before a selection of Securities to be
redeemed or 15 days before an interest payment date.

11.  PERSONS DEEMED OWNERS

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

12.  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.

13.  DISCHARGE AND DEFEASANCE

             Subject to certain conditions, the Company at any time shall be
entitled to terminate some or all of its obligations under the Securities and
the Indenture, and the obligations of the Subsidiary Guarantors under their
Subsidiary Guaranties, 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.

14.  AMENDMENT; WAIVER

             Subject to certain exceptions set forth in the Indenture, (i) the
Indenture and the Securities may be amended with the written consent of the
Holders of at least a majority in principal amount outstanding of the Securities
and (ii) any default or noncompliance with any provision may be waived with the
written consent of the Holders of a

<Page>

                                                                               6

majority in principal amount outstanding of the Securities. Subject to certain
exceptions set forth in the Indenture, without the consent of any
Securityholder, Parent, the Company, the Subsidiary Guarantors and the Trustee
shall be entitled to amend the Indenture or the Securities to cure any
ambiguity, omission, defect or inconsistency, or to comply with Article 5 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, including Subsidiary Guaranties, or to secure the Securities, or to
add additional covenants or surrender rights and powers conferred on the Company
or the Subsidiary Guarantors, or to comply with any request of the SEC in
connection with qualifying the Indenture under the Act, or to make certain
changes in the subordination provisions, or to make any change that does not
adversely affect the rights of any Securityholder.

15.  DEFAULTS AND REMEDIES

             Under the Indenture, Events of Default include (i) default for 30
days in payment of interest on the Securities; (ii) default in payment of
principal on the Securities at maturity, upon redemption pursuant to paragraph 5
of the Securities, upon acceleration or otherwise, or failure by the Company to
redeem or purchase Securities when required; (iii) failure by the Company,
Parent or any Subsidiary Guarantor to comply with other agreements in the
Indenture or the Securities, in certain cases subject to notice and lapse of
time; (iv) certain accelerations (including failure to pay within any grace
period after final maturity) of other Indebtedness of the Company, Parent (so
long as the Existing Contingent Notes have not been satisfied in full and cash
remains in the Contingent Note Reserve), any Subsidiary Guarantor or any
Significant Subsidiary if the amount accelerated (or so unpaid) exceeds $10.0
million; (v) certain events of bankruptcy or insolvency with respect to the
Company, Parent (so long as the Existing Contingent Notes have not been
satisfied in full and cash remains in the Contingent Note Reserve) and the
Significant Subsidiaries; (vi) certain judgments or decrees for the payment of
money in excess of $10.0 million; and (vii) certain defaults with respect to the
Subsidiary Guaranties. 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 indemnity or security
satisfactory to it. 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 (except a Default in payment of principal or interest) if it
determines that withholding notice is not opposed to the interest of the
Holders.

16.  TRUSTEE DEALINGS WITH THE COMPANY

             Subject to certain limitations imposed by the Act, 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.

17.  NO RECOURSE AGAINST OTHERS

             A director, officer, manager, employee,incorporator, member,
partner or stockholder, as such, of the Company, any Subsidiary Guarantor or the
Trustee shall not have any liability for any obligations of the Company under
the Securities or the Indenture or any Subsidiary Guarantor under any Subsidiary
Guaranty, as the case may be, or this Indenture 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.

18.  AUTHENTICATION

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

19.  ABBREVIATIONS

             Customary abbreviations may be used in the name of a Securityholder

20.  CUSIP NUMBERS

             Pursuant to a recommendation promulgated by the Committee on
Uniform Security Identification Procedures the Company has caused CUSIP numbers
to be printed on the Securities and has directed the Trustee to use CUSIP

representation is made as to the accuracy of such numbers either as printed on
the Securities or as contained in any notice of redemption and reliance may be
placed only on the other identification numbers placed thereon.

             Each Holder of a Security, by acceptance hereof, acknowledges and
agrees to the provisions of the Registration Rights Agreement, including the

1.   INTEREST

             Amy Acquisition Corp., 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[; PROVIDED, HOWEVER,
that, to the extent provided in the Registration Rights Agreement, if a
Registration Default (as defined in the Registration Rights Agreement) occurs,
additional interest will accrue on this Security at a rate of 0.25% per annum
(increasing by an additional 0.25% per annum after each consecutive 90-day
period that occurs after the date on which such Registration Default occurs up
to a maximum additional interest rate of 1.00%) from and including the date on
which any such Registration Default shall occur to but excluding the date on
which all Registration Defaults have been cured.](1) The Company will pay
interest semiannually on April 1 and October 1 of each year, commencing October
1, 2003.

             Interest on the Securities will accrue from the most recent date to
which interest has been paid or, if no interest has been paid, from March 27,
2003. Interest on overdue principal will be paid by the Issuer at 1% per annum
in excess of the rate shown above and the Issuer will pay interest on overdue
installments of interest at such higher rate to the extent lawful. Interest will
be computed on the basis of a 360-day year of twelve 30-day months.

             The Company will pay interest on the Securities (except defaulted
interest) to the Persons who are registered holders of Securities at the close

tender for payment of public and private debts. Payments in respect of the
Securities represented by a Global Security (including principal, premium, if
any, and interest) will be made by wire transfer of immediately available funds
to the accounts specified by The Depository Trust Company. The Company will make
all payments in respect of a certificated 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 a certificated Security
will be made 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 30 days immediately preceding the
relevant due date for payment (or such other date as the Trustee may accept in
its discretion).

March 27, 2003 (the "Indenture"), among the Company, AmeriPath Holdings, Inc.,
the guarantors party thereto 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. Section 77aaa-77bbbb) as

authorizes the Trustee to give it effect and appoints the Trustee as
attorney-in-fact for such purpose.

the Company and not to the Trustee for payment.

Government Obligations for the payment of principal and interest on the
Securities to redemption or maturity, as the case may be.

14.  AMENDMENT; WAIVER

             Subject to certain exceptions set forth in the Indenture, (i) the
Indenture and the Securities may be amended with the written consent of the
Holders of at least a majority in principal amount outstanding of the Securities
and (ii) any default or noncompliance with any provision may be waived with the
written consent of the Holders of a majority in principal amount outstanding of
the Securities. Subject to certain exceptions set forth in the Indenture,
without the consent of any Securityholder, Parent, the Company, the Subsidiary
Guarantors and the Trustee shall be entitled to amend the Indenture or the
Securities to cure any ambiguity, omission, defect or inconsistency, or to
comply with Article 5 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, including Subsidiary Guaranties, or
to secure the Securities, or to add additional covenants or surrender rights and
powers conferred on the Company or the Subsidiary Guarantors, or to comply with
any request of the SEC in connection with qualifying the Indenture under the
Act, or to make certain changes in the subordination provisions, or to make any
change that does not adversely affect the rights of any Securityholder.

15.  DEFAULTS AND REMEDIES

             Under the Indenture, Events of Default include (i) default for 30
days in payment of interest on the Securities; (ii) default in payment of
principal on the Securities at maturity, upon redemption pursuant to paragraph 5
of the Securities, upon acceleration or otherwise, or failure by the Company to
redeem or purchase Securities when required; (iii) failure by the Company,
Parent or any Subsidiary Guarantor to comply with other agreements in the
Indenture or the Securities, in certain cases subject to notice and lapse of
time; (iv) certain accelerations (including failure to pay within any grace
period after final maturity) of other Indebtedness of the Company, Parent (so
long as the Existing Contingent Notes have not been satisfied in full and cash
remains in the Contingent Note Reserve), any Subsidiary Guarantor or any
Significant Subsidiary if the amount accelerated (or so unpaid) exceeds $10.0
million; (v) certain events of bankruptcy or insolvency with respect to the
Company, Parent (so long as the Existing Contingent Notes have not been
satisfied in full and cash remains in the Contingent Note Reserve) and the
Significant Subsidiaries; (vi) certain judgments or decrees for the payment of
money in excess of $10.0 million; and (vii) certain defaults with respect to

<Page>

                                                                               7

the Subsidiary Guaranties. 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 indemnity or security
satisfactory to it. 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 (except a Default in payment of principal or interest) if it
determines that withholding notice is not opposed to the interest of the
Holders.

16.  TRUSTEE DEALINGS WITH THE COMPANY

             Subject to certain limitations imposed by the Act, 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.

17.  NO RECOURSE AGAINST OTHERS

             A director, officer, manager, employee, incorporator, member,
partner or stockholder, as such, of the Company, any Subsidiary Guarantor or the
Trustee shall not have any liability for any obligations of the Company under
the Securities or the Indenture or any Subsidiary Guarantor under any Subsidiary
Guaranty, as the case may be, or this Indenture 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.

18.  AUTHENTICATION

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

entireties), JT TEN (=joint tenants with rights of survivorship and not as
tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors

20.  CUSIP NUMBERS

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

                      [FORM OF SUPPLEMENTAL INDENTURE TO BE
                       DELIVERED BY SUBSIDIARY GUARANTORS]

             SUPPLEMENTAL INDENTURE (this "Supplemental Indenture"), dated as of
[ ] among [ ] (the "Subsidiary Guarantor"), a [ ] and a subsidiary of AmeriPath,
Inc., a Delaware corporation (or its permitted successor) (the "Company"), the
Company, AmeriPath Holdings, Inc., a Delaware corporation ("Holdings"), the
other Subsidiary Guarantors and U.S. Bank National Association, as Trustee under
the Indenture (the "Trustee").

                                   WITNESSETH

             WHEREAS, the Company has heretofore executed and delivered to the
Trustee an indenture (the "Indenture"), dated as of March 27, 2003, providing
for the issuance of 10-1/2% Senior Subordinated Notes due 2013 (the
"Securities");

             WHEREAS, pursuant to Section 4.11 of the Indenture, the Company may
cause a Domestic Restricted Subsidiary that Incurs Indebtedness (other than, in
the case of any Consolidated Managed Subsidiary, Indebtedness owed to the
Company or any Subsidiary Guarantor), or a Foreign Subsidiary that enters into a
Guarantee of any Indebtedness of the Company, to execute and deliver to the
Trustee a Guaranty Agreement pursuant to which such Restricted Subsidiary will
Guarantee payment of the Securities on the same terms and conditions as those
set forth in the Indenture; and

             WHEREAS, pursuant to Section 9.01(4) of the Indenture, the Trustee
is authorized to execute and deliver this Supplemental Indenture.

             NOW THEREFORE, in consideration of the foregoing and for good and
valuable consideration, the receipt of which is hereby acknowledged, the
Company, the Subsidiary Guarantor, Holdings the other Subsidiary Guarantors and
the Trustee mutually covenant and agree for the equal and ratable benefit of the
Holders of the Securities as follows:

             SECTION 1. CAPITALIZED TERMS. Capitalized terms used herein but not
defined shall have the meanings assigned to them in the Indenture.

             SECTION 2. GUARANTIES. The Subsidiary Guarantor hereby
unconditionally and irrevocably guarantees, jointly and severally with the other
Subsidiary Guarantors, to each Holder and to the Trustee and its successors and
assigns (a) the full and punctual payment of principal of and interest

<Page>

                                                                               2

on the Securities when due, whether at maturity, by acceleration, by redemption
or otherwise, and all other monetary obligations of the Company under the
Indenture and the Securities and (b) the full and punctual performance within
applicable grace periods of all other obligations of the Company under the
Indenture and the Securities (all the foregoing being hereinafter collectively
called the "Guaranteed Obligations"). The Subsidiary Guarantor further agrees
that the Guaranteed Obligations may be extended or renewed, in whole or in part,
without notice to or further assent from the Subsidiary Guarantor and that the
Subsidiary Guarantor will remain bound under this Supplemental Indenture
notwithstanding any extension or renewal of any Guaranteed Obligation.

             The Subsidiary Guarantor waives presentation to, demand of, payment
from and protest to the Company of any of the Guaranteed Obligations and also
waives notice of protest for nonpayment. The Subsidiary Guarantor waives notice
of any default under the Securities or the Guaranteed Obligations. The
obligations of the Subsidiary Guarantor hereunder shall not be affected by (a)
the failure of any Holder or the Trustee to assert any claim or demand or to
enforce any right or remedy against the Company or any other Person under the
Indenture, this Supplemental 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 the
Indenture, this Supplemental Indenture, the Securities or any other agreement;
(d) the release of any security held by any Holder or the Trustee for the
Guaranteed Obligations or any of them; (e) the failure of any Holder or the
Trustee to exercise any right or remedy against any other guarantor of the
Guaranteed Obligations; or (f) except as set forth in Section 11.06 of the
Indenture, any change in the ownership of the Subsidiary Guarantor.

             The Subsidiary Guarantor further agrees that its Subsidiary
Guaranty herein constitutes a guarantee of payment, performance and compliance
when due (and not a guarantee of collection) and waives any right to require
that any resort be had by any Holder or the Trustee to any security held for
payment of the Guaranteed Obligations.

             The Subsidiary Guaranty is, to the extent and in the manner set
forth in Article 12 of the Indenture, subordinated and subject in right of
payment to the prior payment in full of the principal of and premium, if any,
and interest on all Senior Indebtedness of the Subsidiary

<Page>

                                                                               3

Guarantor and the Subsidiary Guaranty is made subject to the provisions of the
Indenture.

             Except as expressly set forth in Section 8.01(b), 11.02 and 11.06
of the Indenture, the obligations of the Subsidiary Guarantor hereunder shall
not be subject to any reduction, limitation, impairment or termination for any
reason, including any claim of waiver, release, surrender, alteration or
compromise, and shall not be subject to any defense of setoff, counterclaim,
recoupment or termination whatsoever or by reason of the invalidity, illegality
or unenforceability of the Guaranteed Obligations or otherwise. Without limiting
the generality of the foregoing, the obligations of the Subsidiary Guarantor
herein shall not be discharged or impaired or otherwise affected by the failure
of any Holder or the Trustee to assert any claim or demand or to enforce any
remedy under the Indenture, this Supplemental Indenture, the Securities or any
other agreement, by any waiver or modification of any thereof, by any default,
failure or delay, wilful or otherwise, in the performance of the Guaranteed
Obligations, or by any other act or thing or omission or delay to do any other
act or thing which may or might in any manner or to any extent vary the risk of
the Subsidiary Guarantor or would otherwise operate as a discharge of the
Subsidiary Guarantor as a matter of law or equity.

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

             In furtherance of the foregoing and not in limitation of any other
right which any Holder or the Trustee has at law or in equity against the
Subsidiary Guarantor by virtue hereof, upon the failure of the Company to pay
the principal of or interest on any Guaranteed Obligation when and as the same
shall become due, whether at maturity, by acceleration, by redemption or
otherwise, or to perform or comply with any other Guaranteed Obligation, the
Subsidiary Guarantor hereby promises to and shall, upon receipt of written
demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the
Holders or the Trustee an amount equal to the sum of (1) the unpaid amount of
such Guaranteed Obligations, (2) accrued and unpaid interest on such Guaranteed
Obligations (but only to the extent not prohibited by law) and (3) all other
monetary Guaranteed Obligations of the Company to the Holders and the Trustee.

                                                                               4

             The Subsidiary Guarantor agrees that it shall not be entitled to
any right of subrogation in respect of any Guaranteed Obligations guaranteed
hereby until payment in full of all Guaranteed Obligations and all obligations
to which the Guaranteed Obligations are subordinated as provided in Article 12
of the Indenture. The Subsidiary Guarantor agrees that, as between it, on the
one hand, and the Holders and the Trustee, on the other hand, (x) the maturity
of the Guaranteed Obligations may be accelerated as provided in Article 6 of the
Indenture for the purposes of the Subsidiary Guarantor's Subsidiary Guaranty
herein, notwithstanding any stay, injunction or other prohibition preventing
such acceleration in respect of the Guaranteed Obligations, and (y) in the event
of any declaration of acceleration of such Guaranteed Obligations as provided in
Article 6 of the Indenture, such Guaranteed Obligations (whether or not due and
payable) shall forthwith become due and payable by the Subsidiary Guarantor for
the purposes of this Supplemental Indenture.

             The Subsidiary Guarantor also agrees to pay any and all costs and
expenses (including reasonable attorneys' fees) incurred by the Trustee or any
Holder in enforcing any rights under this Section 2.

             SECTION 3. LIMITATION ON LIABILITY. Any term or provision of this
Supplemental Indenture to the contrary notwithstanding, the maximum aggregate
amount of the Guaranteed Obligations by the Subsidiary Guarantor shall not
exceed the maximum amount that can be hereby guaranteed without rendering this
Supplemental Indenture, as it relates to the Subsidiary Guarantor, voidable
under applicable law relating to fraudulent conveyance, fraudulent transfer or
similar laws affecting the rights of creditors generally.

             SECTION 4. SUCCESSORS AND ASSIGNS. This Supplemental Indenture
shall be binding upon the Subsidiary Guarantor and its successors and assigns
and shall inure to the benefit of the successors and assigns of the Trustee and
the Holders and, in the event of any transfer or assignment of rights by any
Holder or the Trustee, the rights and privileges conferred upon that party in
this Supplemental Indenture and in the Securities shall automatically extend to
and be vested in such transferee or assignee, all subject to the terms and
conditions of this Supplemental Indenture.

             SECTION 5. NO WAIVER. Neither a failure nor a delay on the part of
either the Trustee or the Holders in exercising any right, power or privilege
under this Supplemental Indenture shall operate as a waiver thereof, nor shall a
single or partial exercise thereof preclude any

<Page>

                                                                               5

other or further exercise of any right, power or privilege. The rights, remedies
and benefits of the Trustee and the Holders herein expressly specified are
cumulative and not exclusive of any other rights, remedies or benefits which
either may have under this Supplemental Indenture at law, in equity, by statute
or otherwise.

             SECTION 6. MODIFICATION. No modification, amendment or waiver of
any provision of this Supplemental Indenture, nor the consent to any departure
by the Subsidiary Guarantor therefrom, shall in any event be effective unless
the same shall be in writing and signed by the Trustee, and then such waiver or
consent shall be effective only in the specific instance and for the purpose for
which given. No notice to or demand on the Subsidiary Guarantor in any case
shall entitle the Subsidiary Guarantor to any other or further notice or demand
in the same, similar or other circumstances.

             SECTION 7. RELEASE. Upon

             (i)    the sale (including any sale pursuant to any exercise of
     remedies by a holder of Senior Indebtedness of the Company or of such
     Subsidiary Guarantor) or other disposition (including by way of
     consolidation or merger) of the Subsidiary Guarantor,

             (ii)   the sale or disposition of all or substantially all the
     assets of the Subsidiary Guarantor or

             (iii)  upon the designation of the Subsidiary Guarantor as an
     Unrestricted Subsidiary pursuant to the terms of the Indenture,

the Subsidiary Guarantor shall be deemed released from all obligations under
this Supplemental Indenture without any further action required on the part of
the Trustee or any Holder, in each case other than a sale or disposition to
Parent or a Subsidiary of Parent, PROVIDED, HOWEVER, in the case of clauses (i)
and (ii) above, the Company provides an Officers' Certificate to the Trustee to
the effect that the Company will comply with its obligations under Section 4.06
of the Indenture.

             SECTION 8. CONTRIBUTION. The Subsidiary Guarantor shall be entitled
upon payment in full of all guarantied obligations under this Supplemental
Indenture to a contribution from each other Subsidiary Guarantor in an amount
equal to such other Subsidiary Guarantor's pro rata portion of such payment
based on the respective net assets

                                                                               6

of all the Subsidiary Guarantors at the time of such payment determined in
accordance with GAAP.

             SECTION 9. GOVERNING LAW. This Supplemental Indenture shall be
governed by, and construed in accordance with, the laws of the State of New
York.

             SECTION 10. NO RECOURSE AGAINST OTHERS. A director, officer,
employee, incorporates, partner, stockholder, member or manager, as such, of the
Subsidiary Guarantor shall not have any liability for any obligations of Parent
or the Company under the Securities or the indenture or of the Subsidiary
Guarantor under its Subsidiary Guaranty, the Indenture or this Supplemental
Indenture or for any claim based on, in respect of or by reason of such
obligations or their creation. By accepting a Security, each Holder waives and
releases all such liability. The waiver and release shall be part of the
consideration for the issue of the Securities.

             SECTION 11. MULTIPLE ORIGINALS. The parties may sign any number of
copies of this Supplemental 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 Supplemental Indenture.

             SECTION 12. HEADINGS. The headings of the Sections of this
Supplemental Indenture have been inserted for convenience of reference only, are
not intended to be considered a part hereof and shall not modify or restrict any
of the terms or provisions hereof.

             IN WITNESS WHEREOF, the parties have caused this Supplemental
Indenture to be duly executed as of the date first written above.
