     WITNESSETH

     WHEREAS, the Issuer and the Original Guarantors have previously executed
and delivered to the Trustee an indenture (the "Indenture"), dated as of April
22, 1999, providing for the issuance of an aggregate principal amount of up to
$350,000,000 of 9% Senior Subordinated Notes due 2009;

     WHEREAS, the Issuer has completed a corporate restructuring, which
included, among other things, the formation of the Guarantying Subsidiary and
the merger of Hydro Flame Corporation, an Original Guarantor under the
Indenture, with and into the Guarantying Subsidiary.

     WHEREAS, Section 11.05 of the Indenture provides that the person acquiring
the property of a Guarantor in a merger must assume all of the obligations of
the Guarantor under the Indenture pursuant to a Supplemental Indenture; and

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

     NOW THEREFORE, in consideration of the foregoing and for other good and
valuable consideration, the receipt of which is hereby acknowledged, the parties
hereto mutually covenant and agree for the equal and ratable benefit of the
Holders of the Securities as follows:

     1.   Agreement to Guarantee. The Guaranteeing Subsidiary hereby agree as
          follows:

     (a)  Along with all Guarantors named in the Indenture, to unconditionally
          guarantee (each such guarantee to be referred to herein as a "Note
          Guarantee") to each Holder of a Note authenticated and delivered by
          the Trustee and to the Trustee and its successors and

<PAGE>   2

          assigns, irrespective of the validity and enforceability of this
          Supplemental Indenture, the Notes or the obligations of the Issuer
          hereunder or thereunder, that: (i) the principal of and interest on
          the Notes will be promptly paid in full when due, whether at maturity,
          by acceleration, redemption or otherwise, and interest on the overdue
          principal of and interest on the Notes, if any, if lawful, and all
          other obligations of the Issuer to the Holders or the Trustee
          hereunder or thereunder will be promptly paid in full or performed,
          all in accordance with the terms hereof and thereof; and (ii) in case
          of any extension of time of payment or renewal of any Notes or any of
          such other obligations, that same will be promptly paid in full when
          due or performed in accordance with the terms of the extension or
          renewal, whether at stated maturity, by acceleration or otherwise.
          Failing payment when due of any amount so guaranteed or any
          performance so guaranteed for whatever reason, the Guaranteeing
          Subsidiary shall be jointly and severally obligated to pay the same
          immediately. The Guaranteeing Subsidiary agrees that this is a
          guarantee of payment and not a guarantee of collection.

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

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

     (d)  The Guaranteeing Subsidiary agrees that it shall not be entitled to
          any right of subrogation in relation to the Holders in respect of any
          Note Guarantee until payment in full of all obligations guaranteed
          under this Supplemental Indenture. The Guaranteeing Subsidiary 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 obligations
          guaranteed hereby may be accelerated as provided in Article 6 of the
          Indenture for the purposes of this Note Guarantee, notwithstanding any
          stay, injunction or other prohibition preventing such acceleration in

                                       2
<PAGE>   3

          respect of the obligations guaranteed hereby, and (y) in the event of
          any declaration of acceleration of such obligations as provided in
          Article 6 of the Indenture, such obligations (whether or not due and
          payable) shall forthwith become due and payable by the Guaranteeing
          Subsidiary for the purpose of this Note Guarantee. The Guaranteeing
          Subsidiary shall have the right to seek contribution from any
          non-paying Guarantor so long as the exercise of such right does not
          impair the rights of the Holders under this Note Guarantee.

     2. Incorporation of Terms of Indenture. The obligations of the Guaranteeing
Subsidiary under the Note Guarantees shall be governed in all respects by the
terms of the Indenture and shall constitute a Guarantee thereunder. Each of the
parties hereto shall be bound by the terms of the Indenture as they relate to
the Note Guarantees.

     3. No Recourse Against Others. No stockholder, officer, director, employee
or incorporator, past, present or future, or the Guaranteeing Subsidiary, as
such, shall have any personal liability under this Note Guarantee by reason of
his, her or its status as such stockholder, officer, director, employee or
incorporator.

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

     5. Counterparts. 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.

     6. Effect of Headings. The Section headings herein are for convenience only
and shall not affect the construction hereof.

     7. Disclaimer by Trustee. The Trustee makes no representation as to the
validity of this Supplemental Indenture or the proper authorization or due
execution of this Supplemental Indenture by the Issuer, the Original Guarantors
or the Guaranteeing Subsidiary.

written.

              (C) if the transfer will be made pursuant to any other exemption
     from the registration requirements of the Securities Act, then the
     transferor must deliver a certificate in the form of Exhibit B hereto,
     including the certifications, certificates and Opinion of Counsel required
     by item (3) thereof, if applicable.

          (ii) Restricted Definitive Notes to Unrestricted Definitive Notes. Any
     Restricted Definitive Note may be exchanged by the Holder thereof for an
     Unrestricted Definitive Note or transferred to a Person or Persons who take
     delivery thereof in the form of an Unrestricted Definitive Note if:

              (A) such exchange or transfer is effected pursuant to the Exchange
     Offer in accordance with the Registration Rights Agreement and the Holder,
     in the case of an exchange, or the transferee, in the case of a transfer,
     certifies in the applicable Letter of Transmittal that it is not (1) a
     broker-dealer, (2) a Person participating in the distribution of the
     Exchange Notes or (3) a Person who is an affiliate (as defined in Rule 144)
     of the Company;

              (B) any such transfer is effected pursuant to the Shelf
     Registration Statement in accordance with the Registration Rights
     Agreement;

              (C) any such transfer is effected by a Broker-Dealer pursuant to
     the Exchange Offer Registration Statement in accordance with the
     Registration Rights Agreement; or

              (D) the Registrar receives the following:

                                       33
<PAGE>   39

                       (1) if the Holder of such Restricted Definitive Notes
         proposes to exchange such Notes for an Unrestricted Definitive Note, a
         certificate from such Holder in the form of Exhibit C hereto, including
         the certifications in item (1)(d) thereof; or

                       (2) if the Holder of such Restricted Definitive Notes
         proposes to transfer such Notes to a Person who shall take delivery
         thereof in the form of an Unrestricted Definitive Note, a certificate
         from such Holder in the form of Exhibit B hereto, including the
         certifications in item (4) thereof;

                       and, in each such case set forth in this subparagraph
         (D), if the Registrar so requests, an Opinion of Counsel in form
         reasonably acceptable to the Company to the effect that such exchange
         or transfer is in compliance with the Securities Act and that the
         restrictions on transfer contained herein and in the Private Placement
         Legend are no longer required in order to maintain compliance with the
         Securities Act.

                   (iii) Unrestricted Definitive Notes to Unrestricted
         Definitive Notes. A Holder of Unrestricted Definitive Notes may
         transfer such Notes to a Person who takes delivery thereof in the form
         of an Unrestricted Definitive Note. Upon receipt of a request to
         register such a transfer, the Registrar shall register the Unrestricted
         Definitive Notes pursuant to the instructions from the Holder thereof.

     (f) Exchange Offer.

         Upon the occurrence of the Exchange Offer in accordance with the
Registration Rights Agreement, the Company shall issue and, upon receipt of an
Authentication Order in accordance with Section 2.02, the Trustee shall
authenticate (i) one or more Unrestricted Global Notes in an aggregate principal
amount equal to the principal amount of the beneficial interests in the global
notes evidencing the Existing Notes accepted for exchange in the Exchange Offer
and the Restricted Global Notes tendered for acceptance by Persons that certify
in the applicable Letters of Transmittal that (x) they are not broker-dealers,
(y) they are not participating in a distribution of the Exchange Notes and (z)
they are not affiliates (as defined in Rule 144) of the Company, and accepted
for exchange in the Exchange Offer, and (ii) Definitive Notes in an aggregate
principal amount equal to the principal amount of the Restricted Definitive
Notes and the definitive Existing Notes accepted for exchange in the Exchange
Offer. Concurrently with the issuance of such Notes, the Trustee shall cause the
aggregate principal amount of the applicable Restricted Global Notes to be
reduced accordingly, and the Company shall execute and the Trustee shall
authenticate and deliver to the Persons designated by the Holders of Definitive
Notes so accepted Definitive Notes in the appropriate principal amount.

         (g) Legends.

         The following legends shall appear on the face of all Global Notes and
Definitive Notes issued under this Indenture unless specifically stated
otherwise in the applicable provisions of this Indenture.

         (i) Private Placement Legend.

              (A) Except as permitted by subparagraph (B) below, each Global

         therefor or substitution

                                       34
<PAGE>   40

     thereof) shall bear the legend in substantially the following form:

         THE NOTE (OR ITS PREDECESSORS) EVIDENCED HEREBY WAS ORIGINALLY ISSUED
IN A TRANSACTION EXEMPT FROM REGISTRATION UNDER SECTION 5 OF THE UNITED STATES
SECURITIES ACT OF 1933, AS AMENDED, AND THE NOTE EVIDENCED HEREBY MAY NOT BE
OFFERED, SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN
APPLICABLE EXEMPTION THEREFROM. EACH PURCHASER OF THE NOTE EVIDENCED HEREBY IS
HEREBY NOTIFIED THAT THE SELLER MAY BE RELYING ON THE EXEMPTION FROM THE
PROVISIONS OF SECTION 5 OF THE SECURITIES ACT PROVIDED BY RULE 144A THEREUNDER
OR ANOTHER EXEMPTION UNDER THE SECURITIES ACT. THE HOLDER OF THE NOTE EVIDENCED
HEREBY AGREES FOR THE BENEFIT OF THE COMPANY THAT (A) SUCH NOTE MAY BE RESOLD,
PLEDGED OR OTHERWISE TRANSFERRED ONLY (I) (A) TO A PERSON WHO THE SELLER
REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER (AS DEFINED IN RULE 144A
UNDER THE SECURITIES ACT), PURCHASING FOR ITS OWN ACCOUNT IN A TRANSACTION
MEETING THE REQUIREMENTS OF RULE 144A UNDER THE SECURITIES ACT, (B) IN A
TRANSACTION MEETING THE REQUIREMENTS OF RULE 144 OF THE SECURITIES ACT, (C)
OUTSIDE THE UNITED STATES TO A FOREIGN PERSON IN A TRANSACTION MEETING THE
REQUIREMENTS OF RULE 904 OF REGULATION S UNDER THE SECURITIES ACT OR (D) IN
ACCORDANCE WITH ANOTHER EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE

SUCH TRANSFER IS EFFECTED BY THE DELIVERY TO THE TRANSFEREE OF DEFINITIVE
SECURITIES REGISTERED IN ITS NAME (OR ITS NOMINEES NAME) IN THE BOOKS MAINTAINED
BY THE REGISTRAR, AND IS SUBJECT TO THE RECEIPT BY THE REGISTRAR (AND THE
COMPANY, IF THEY SO REQUEST) OF A CERTIFICATION OF THE TRANSFEROR AND AN OPINION
OF COUNSEL TO THE EFFECT THAT SUCH TRANSFER IS IN COMPLIANCE WITH THE SECURITIES
ACT, (II) TO THE COMPANY OR (III) PURSUANT TO AN EFFECTIVE REGISTRATION
STATEMENT UNDER THE SECURITIES ACT AND, IN EACH CASE, IN ACCORDANCE WITH ANY
APPLICABLE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES OR ANY OTHER
APPLICABLE JURISDICTION AND (B) THE HOLDER WILL, AND EACH SUBSEQUENT HOLDER IS
REQUIRED TO, NOTIFY ANY PURCHASER FROM IT OF THE NOTE EVIDENCED HEREBY OF THE
RESALE RESTRICTIONS SET FORTH IN (A) ABOVE.

                       (B) Notwithstanding the foregoing, any Global Note or
         Definitive Note issued pursuant to subparagraphs (b)(iv), (c)(ii),
         (c)(iii), (d)(ii), (d)(iii), (e)(ii), (e)(iii) or (f) to this Section
         2.06 (and all Notes issued in exchange therefor or substitution
         thereof) shall not bear the Private Placement Legend.

              (ii) Global Note Legend. Each Global Note shall bear a legend in
         substantially the following form:

              "This Global Note is held by the Depositary (as defined in the
         Indenture governing this Note) or its nominee in custody for the
         benefit of the beneficial owners hereof, and is not transferable to any
         person under any circumstances except that (i) the Trustee may make
         such notations hereon as may be required pursuant to section 2.07 of
         this Indenture, (ii) this Global Note may be exchanged in whole but not
         in part pursuant to section 2.06(a) of this

                                       35
<PAGE>   41

         Indenture, (iii) this Global Note may be delivered to the Trustee for
         cancellation pursuant to section 2.11 of this Indenture, and (iv) this
         Global Note may be transferred to a successor depositary with the prior
         written consent of the Company."

         (h) Cancellation and/or Adjustment of Global Notes.

              At such time as all beneficial interests in a particular Global
Note have been exchanged for Definitive Notes or a particular Global Note has
been redeemed, repurchased or canceled in whole and not in part, each such
Global Note shall be returned to or retained and canceled by the Trustee in
accordance with Section 2.11 hereof. At any time prior to such cancellation, if
any beneficial interest in a Global Note is exchanged for or transferred to a
Person who will take delivery thereof in the form of a beneficial interest in
another Global Note or for Definitive Notes, the principal amount of Notes
represented by such Global Note shall be reduced accordingly and an endorsement
shall be made on such Global Note by the Trustee or by the Depositary at the
direction of the Trustee to reflect such reduction; and if the beneficial
interest is being exchanged for or transferred to a Person who will take
delivery thereof in the form of a beneficial interest in another Global Note,
such other Global Note shall be increased accordingly and an endorsement shall
be made on such Global Note by the Trustee or by the Depositary at the direction
of the Trustee to reflect such increase.

     (i) General Provisions Relating to Transfers and Exchanges.

          (i) To permit registrations of transfers and exchanges, the Company
     shall execute and the Trustee shall authenticate Global Notes and
     Definitive Notes upon the Company's order or at the Registrar's request.

          (ii) No service charge shall be made to a holder of a beneficial
     interest in a Global Note or to a Holder of a Definitive Note for any
     registration of transfer or exchange, but the Company may require payment
     of a sum sufficient to cover any transfer tax or similar governmental
     charge payable in connection therewith (other than any such transfer taxes
     or similar governmental charge payable upon exchange or transfer pursuant
     to Sections 2.10, 3.06, 3.09, 4.10, 4.15 and 9.05 hereof).

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

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

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

                                       36
<PAGE>   42

     redeemed in part or (c) to register the transfer of or to exchange a Note
     between a record date and the next succeeding Interest Payment Date.

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

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

          (viii) All certifications, certificates and Opinions of Counsel
     required to be submitted to the Registrar pursuant to this Section 2.06 to
     effect a registration of transfer or exchange may be submitted by
     facsimile.

SECTION 2.07. Replacement Notes.

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

          Every replacement Note issued pursuant to this Section 2.07 is an
additional obligation of the Company and shall be entitled to all of the
benefits of this Indenture equally and proportionately with all other Notes duly
issued hereunder.

SECTION 2.08. Outstanding Notes.

          The Notes outstanding at any time are all the Notes authenticated by
the Trustee except for those canceled by it, those delivered to it for
cancellation, those reductions in the interest in a Global Note effected by the
Trustee in accordance with the provisions hereof, and those described in this
Section as not outstanding. Except as set forth in Section 2.09 hereof, a Note
does not cease to be outstanding because the Company or an Affiliate of the
Company holds the Note; however, Notes held by the Company or a Subsidiary of
the Company shall not be deemed to be outstanding for purposes of Section
3.07(b) hereof.

          If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be
outstanding unless the Trustee receives proof satisfactory to it that the
replaced Note is held by a bona fide purchaser.

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

          If the Paying Agent (other than the Company, a Subsidiary or an
Affiliate of any thereof) holds, on a redemption date or maturity date, money
sufficient to pay Notes payable on that date, then on

                                       37
<PAGE>   43

and after that date such Notes shall be deemed to be no longer outstanding and
shall cease to accrue interest.

SECTION 2.09. Treasury Notes.

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

SECTION 2.10. Temporary Notes.

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

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

SECTION 2.11. Cancellation.

          The Company at any time may deliver Notes to the Trustee for
cancellation. The Registrar and Paying Agent shall forward to the Trustee any
Notes surrendered to them for registration of transfer, exchange or payment. The
Trustee and no one else shall cancel all Notes surrendered for registration of
transfer, exchange, payment, replacement or cancellation and shall destroy
canceled Notes (subject to the record retention requirement of the Exchange
Act). Certification of the destruction of all canceled Notes shall be delivered
to the Company. Subject to Section 2.07, the Company may not issue new Notes to
replace Notes that it has paid or that have been delivered to the Trustee for
cancellation.

SECTION 2.12. Defaulted Interest.

          If the Company defaults in a payment of interest on the Notes, it
shall pay the defaulted interest in any lawful manner plus, to the extent
lawful, interest payable on the defaulted interest, to the Persons who are
Holders on a subsequent special record date, in each case at the rate provided
in the Notes and in Section 4.01 hereof. The Company shall notify the Trustee in
writing of the amount of defaulted interest proposed to be paid on each Note and
the date of the proposed payment. The Company shall fix or cause to be fixed
each such special record date and payment date, provided that no such special
record date shall be less than 10 days prior to the related payment date for
such defaulted interest. At least 15 days before the special record date, the
Company (or, upon the written request of the Company, the Trustee in the name
and at the expense of the Company) shall mail or cause to be mailed to Holders a
notice that states the special record date, the related payment date and the
amount of such interest to be paid.

                                       38
<PAGE>   44

SECTION 2.13. CUSIP Numbers.

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

                                   ARTICLE 3.
                            REDEMPTION AND PREPAYMENT

SECTION 3.01. Notices to Trustee.

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

SECTION 3.02. Selection of Notes to Be Redeemed.

          If less than all of the Notes are to be redeemed at any time, the
Trustee shall select Notes for redemption as follows:

     (a)  if the Notes are listed, in compliance with the requirements of the
          principal national securities exchange on which the Notes are listed;
          or

     (b)  if the Notes are not so listed, on a pro rata basis, by lot or by such
          method as the Trustee shall deem fair and appropriate.

          In the event of partial redemption by lot, the particular Notes to be
redeemed shall be selected, unless otherwise provided herein, not less than 30
nor more than 60 days prior to the redemption date by the Trustee from the
outstanding Notes not previously called for redemption.

          The Trustee shall promptly notify the Company in writing of the Notes
selected for redemption and, in the case of any Note selected for partial
redemption, the principal amount thereof to be redeemed. Notes and portions of
Notes selected shall be in amounts of $1,000 or whole multiples of $1,000;
except that if all of the Notes of a Holder are to be redeemed, the entire
outstanding amount of Notes held by such Holder, even if not a multiple of
$1,000, shall be redeemed. Except as provided in the preceding sentence,
provisions of this Indenture that apply to Notes called for redemption also
apply to portions of Notes called for redemption.

SECTION 3.03. Notice of Redemption.

          Subject to the provisions of Section 3.09 hereof, at least 30 days but
not more than 60 days before a redemption date, the Company shall mail or cause
to be mailed, by first class mail, a

                                       39
<PAGE>   45

notice of redemption to each Holder whose Notes are to be redeemed at its
registered address.

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

          (a) the redemption date;

          (b) the redemption price;

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

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

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

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

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

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

          At the Company's request, the Trustee shall give the notice of
redemption in the Company's name and at its expense; provided, however, that the
Company shall have delivered to the Trustee, at least 45 days prior to the
redemption date, an Officers' Certificate requesting that the Trustee give such
notice and setting forth the information to be stated in such notice as provided
in the preceding paragraph.

          For so long as the Notes are listed on the Luxembourg Stock Exchange
and the rules of such exchange so require, the Company will cause a notice of
redemption of the Notes to be published in a daily newspaper with general
circulation in Luxembourg (which is expected to be the Luxembourger Wort).
Notices of redemption may not be conditional.

SECTION 3.04. Effect of Notice of Redemption.

          Once notice of redemption is mailed in accordance with Section 3.03
hereof, Notes called for redemption become irrevocably due and payable on the
redemption date at the redemption price. A notice of redemption may not be
conditional.

SECTION 3.05. Deposit of Redemption Price.

          On or before the redemption date, the Company shall deposit with the
Trustee or with the Paying Agent money sufficient to pay the redemption price of
and accrued interest on all Notes to be

                                       40
<PAGE>   46

redeemed on that date. The Trustee or the Paying Agent shall promptly return to
the Company any money deposited with the Trustee or the Paying Agent by the
Company in excess of the amounts necessary to pay the redemption price of, and
accrued interest on, all Notes to be redeemed.

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

SECTION 3.06. Notes Redeemed in Part.

          Upon surrender of a Note that is redeemed in part, the Company shall
issue and, upon the Company's written request, the Trustee shall authenticate
for the Holder at the expense of the Company a new Note equal in principal
amount to the unredeemed portion of the Note surrendered.

SECTION 3.07. Optional Redemption.

          (a) At any time prior to May 1, 2002, the Company may redeem up to 35%
of the aggregate principal amount of Notes issued under this Indenture
(calculated after giving effect to any issuance of Additional Notes) at a
redemption price of 109% of the principal amount thereof, plus accrued and
unpaid interest and Liquidated Damages thereon, if any, to the redemption date,
with the net cash proceeds of one or more Equity Offerings; provided that:

          (i) at least 65% of the aggregate principal amount of Notes issued
     under this Indenture remains outstanding immediately after the occurrence
     of such redemption (excluding Notes held by DASI, the Company and their
     respective Subsidiaries); and

          (ii) the redemptions must occur within 90 days of the date of the
     closing of any such Equity Offering.

          (b) Except pursuant to the preceding paragraph, the Notes will not be
     redeemable at the Company's option prior to May 1, 2004.

     After May 1, 2004, the Company may redeem all or a part of the Notes upon
not less than 30 nor more than 60 days' notice, at the redemption prices
(expressed as percentages of principal amount) set forth below plus accrued and
unpaid interest and Liquidated Damages thereon, if any, to the applicable
redemption date, if redeemed during the twelve-month period beginning on May 1
of the years indicated below:

          In the event that, pursuant to Section 4.10 hereof, the Company shall
be required to commence an offer to all Holders to purchase Notes (an "Asset
Sale Offer"), it shall follow the procedures specified below.

          The Asset Sale Offer shall remain open for a period of 20 Business
Days following its commencement and no longer, except to the extent that a
longer period is required by applicable law (the "Offer Period"). No later than
five Business Days after the termination of the Offer Period (the "Purchase
Date"), the Company shall purchase the principal amount of Notes required to be
purchased pursuant to Section 4.10 hereof (the "Offer Amount") or, if less than
the Offer Amount has been tendered, all Notes tendered in response to the Asset
Sale Offer. Payment for any Notes so purchased shall be made in the same manner
as interest payments are made.

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

          Upon the commencement of an Asset Sale Offer, the Company shall send,
by first class mail, a notice to the Trustee and each of the Holders, with a
copy to the Trustee. The notice shall contain all instructions and materials
necessary to enable such Holders to tender Notes pursuant to the Asset Sale
Offer. The Asset Sale Offer shall be made to all Holders. The notice, which
shall govern the terms of the Asset Sale Offer, shall state:

     (a) that the Asset Sale Offer is being made pursuant to this Section 3.09
and Section 4.10 hereof and the length of time the Asset Sale Offer shall remain
open;

     (b) the Offer Amount, the purchase price and the Purchase Date;

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

                                       42
<PAGE>   48

     (d) that, unless the Company defaults in making such payment, any Note
accepted for payment pursuant to the Asset Sale Offer shall cease to accrue
interest after the Purchase Date;

     (e) that Holders electing to have a Note purchased pursuant to an Asset
Sale Offer may only elect to have all of such Note purchased and may not elect
to have only a portion of such Note purchased;

     (f) that Holders electing to have a Note purchased pursuant to any Asset
Sale Offer shall be required to surrender the Note, with the form entitled
"Option of Holder to Elect Purchase" on the reverse of the Note completed, or
transfer by book-entry transfer, to the Company, a depositary, if appointed by
the Company, or a Paying Agent at the address specified in the notice at least
three days before the Purchase Date;

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

     (h) that, if the aggregate principal amount of Notes surrendered by Holders
exceeds the Offer Amount, the Company shall select the Notes to be purchased on
a pro rata basis (with such adjustments as may be deemed appropriate by the
Company so that only Notes in denominations of $1,000, or integral multiples
thereof, shall be purchased); and

     (i) that Holders whose Notes were purchased only in part shall be issued
new Notes equal in principal amount to the unpurchased portion of the Notes
surrendered (or transferred by book-entry transfer).

          On or before the Purchase Date, the Company shall, to the extent
lawful, accept for payment, on a pro rata basis to the extent necessary, the
Offer Amount of Notes or portions thereof tendered pursuant to the Asset Sale
Offer, or if less than the Offer Amount has been tendered, all Notes tendered,
and shall deliver to the Trustee an Officers' Certificate stating that such
Notes or portions thereof were accepted for payment by the Company in accordance
with the terms of this Section 3.09. The Company, the Depositary or the Paying
Agent, as the case may be, shall promptly (but in any case not later than five
days after the Purchase Date) mail or deliver to each tendering Holder an amount
equal to the purchase price of the Notes tendered by such Holder and accepted by
the Company for purchase, and the Company shall promptly issue a new Note, and
the Trustee, upon written request from the Company shall authenticate and mail
or deliver such new Note to such Holder, in a principal amount equal to any
unpurchased portion of the Note surrendered. Any Note not so accepted shall be
promptly mailed or delivered by the Company to the Holder thereof. The Company
shall publicly announce the results of the Asset Sale Offer on the Purchase
Date.

          Other than as specifically provided in this Section 3.09, any purchase
pursuant to this Section 3.09 shall be made pursuant to the provisions of
Sections 3.01 through 3.06 hereof.

of, premium, if any, and interest and Liquidated Damages, if any, on the Notes
on the dates and in the manner provided in the Notes. Principal, premium, if
any, and interest and Liquidated Damages, if any, shall be considered paid on

thereof, holds as of 10:00 a.m. Eastern Time on the due date money deposited by
the Company in immediately available funds and designated for and sufficient to
pay all principal, premium, if any, and interest and Liquidated Damages, if any,

Notes to the extent lawful; it shall pay interest (including post-petition
interest in any proceeding under any Bankruptcy Law) on overdue installments of
interest and Liquidated Damages (without regard to any applicable grace period)
at the same rate to the extent lawful.

SECTION 4.02. Maintenance of Office or Agency.

may be surrendered for registration of transfer or for exchange and where
notices and demands to or upon the Company in respect of the Notes and this
Indenture may be served. The Company shall give prompt written notice to the
Trustee of the location, and any change in the location, of such office or

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

          The Company may also from time to time designate one or more other
offices or agencies where the Notes may be presented or surrendered for any or
all such purposes and may from time to time rescind such designations; provided,
however, that no such designation or rescission shall in any manner relieve the
Company of its obligation to maintain an office or agency in the Borough of
Manhattan, the City of New York, and for so long as the Notes are listed on the
Luxembourg Stock Exchange, in Luxembourg for such purposes. The Company shall
give prompt written notice to the Trustee of any such designation or rescission
and of any change in the location of any such other office or agency.

          The Company hereby designates the Corporate Trust Office of the
Trustee as one such office or agency of the Company in accordance with Section

     and, with respect to the annual information only, a report on the annual
     financial statements by the Company's certified independent accountants;
     and

          (ii) all current reports that would be required to be filed with the

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

so long as any Notes remain outstanding, it shall furnish to the Holders and to
securities analysts and prospective investors, upon their request, the

interpretations of SAB 53; provided that DASI does not have any business
operations other than those conducted through the Company.

respect thereto. For purposes this paragraph, such compliance shall be
determined without regard to any period of grace or requirement of notice under
this Indenture.

American Institute of Certified Public Accountants, the year-end financial
statements delivered pursuant to Section 4.03(i) above shall be accompanied by a
written statement of the Company's independent public accountants (who shall be
a firm of established national reputation) that in making the examination
necessary for certification of such financial statements, nothing has come to
their attention that would lead them to believe that the Company has violated
any provisions of Article 4 or Article 5 hereof or, if any such violation has
occurred, specifying the nature and period of existence thereof, it being
understood that such accountants shall not be liable directly or indirectly to
any Person for any failure to obtain knowledge of any such violation.

     (c) The Company shall, so long as any of the Notes are outstanding, deliver

to the Holders of the Notes.

SECTION 4.06. Stay, Extension and Usury Laws.

     The Company and each of the Guarantors covenants (to the extent that it may
lawfully do so) that it shall not at any time insist upon, plead, or in any
manner whatsoever claim or take the benefit or advantage of, any stay, extension
or usury law wherever enacted, now or at any time hereafter in force, that may
affect the covenants or the performance of this Indenture; and the Company and
each of the Guarantors (to the extent that it may lawfully do so) hereby
expressly waives all benefit or advantage of any such law, and covenants that it
shall not, by resort to any such law, 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 has been enacted.

     stock sale agreements and other similar agreements entered into in the
     ordinary course of business;

          (xi) restrictions on cash or other deposits or net worth imposed by
     customers under contracts entered into in the ordinary course of business;

          (xii) customary provisions in agreements with respect to Permitted
     Joint Ventures;

          (xiii) Indebtedness incurred after the date of this Indenture in
     accordance with the terms of this Indenture; provided; that the
     restrictions contained in the agreements governing such new Indebtedness
     are, in the good faith judgment of the Board of Directors of the Company,
     not materially less favorable, taken as a whole, to the holders of the
     Notes than those contained in the agreements governing Indebtedness
     outstanding on the date of this Indenture;

          (xiv) any encumbrance or restriction of a Securitization Entity
     effected in connection with a Qualified Securitization Transaction; and

          (xv) any encumbrances or restrictions imposed by any amendments,
     modifications, restatements, renewals, increases, supplements, refundings,
     replacements or refinancings of the contracts, instruments or obligations
     referred to in clauses (i) through (xiv) above; provided that such
     amendments, modifications, restatements, renewals, increases, supplements,
     refundings, replacements or refinancings are, in the good faith judgment of
     the Board of Directors of the Company, no more restrictive with respect to
     such dividend and other payment restrictions prior to such amendment,
     modification, restatement, renewal, increase, supplement, refunding,
     replacement or refinancing.

SECTION 4.09. Incurrence of Indebtedness and Issuance of Preferred Stock.

          The Company shall not, and shall not permit any of its Subsidiaries
to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise
become directly or indirectly liable, contingently or otherwise, with respect to
(collectively, "incur") any Indebtedness (including Acquired Debt), and the
Company shall not issue any Disqualified Stock and shall not permit any of its
Subsidiaries to issue any shares of preferred stock; provided, however, that the
Company may incur Indebtedness (including Acquired Debt) or issue Disqualified
Stock, and the Guarantors may incur Indebtedness (including Acquired Debt) or
issue preferred stock, if in each case the Fixed Charge Coverage Ratio for the
Company's most recently ended four full fiscal quarters for which internal
financial statements are available immediately preceding the date on which such
additional Indebtedness is incurred or such Disqualified Stock or preferred
stock is issued would have been at least 2.0 to 1.0, determined on a pro forma
basis (including a pro forma application of the net proceeds therefrom), as if
the additional Indebtedness had been incurred, or the preferred stock or
Disqualified Stock had been issued, as the case may be, at the beginning of such
four-quarter period.

          The first paragraph of this Section 4.09 shall not prohibit the
incurrence of any of the following items of Indebtedness (collectively,
"Permitted Debt"):

                                       51
<PAGE>   57

          (i) the incurrence by the Company and any Restricted Subsidiary of
     Indebtedness and letters of credit under Credit Facilities in an aggregate
     principal amount at any one time outstanding under this clause (i) (with
     letters of credit being deemed to have a principal amount equal to the
     maximum potential liability of the Company and its Restricted Subsidiaries
     thereunder) not to exceed $950.0 million less any mandatory prepayments
     actually made thereunder (to the extent, in the case of payments of
     revolving credit Indebtedness, that the corresponding commitments have been
     permanently reduced) or scheduled payments actually made thereunder (other
     than the repayment of the Interim Term Loan using the net proceeds from the
     sale of the Initial Notes);

          (ii) the incurrence by the Company and its Restricted Subsidiaries of
     the Existing Indebtedness;

          (iii) the incurrence by the Company and the Guarantors of Indebtedness
     represented by the Notes and the related Guaranties to be issued on the
     date of this Indenture and the Exchange Notes and the related Guaranties to
     be issued pursuant to the Registration Rights Agreement (including the
     Exchange Notes and related Guaranties to be issued in exchange for the
     Existing Notes);

          (iv) the incurrence by the Company or any of its Restricted
     Subsidiaries of Indebtedness represented by Capital Lease Obligations,
     mortgage financings or purchase money obligations, in each case, incurred
     for the purpose of financing all or any part of the purchase price or cost
     of construction or improvement of property, plant or equipment used in the
     business of the Company or such Restricted Subsidiary, in an aggregate
     principal amount, including all Permitted Refinancing Indebtedness incurred
     to refund, refinance or replace any Indebtedness incurred pursuant to this
     clause (iv), not to exceed 5% of Total Assets at any time outstanding;

          (v) the incurrence by the Company or any of its Restricted
     Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the
     net proceeds of which are used to refund, refinance or replace,
     Indebtedness (other than intercompany Indebtedness) that was permitted by
     this Indenture to be incurred under the first paragraph of this Section
     4.09 or clauses (ii), (iii), (iv), (v) or (x) of this paragraph;

          (vi) the incurrence by the Company or any of its Restricted
     Subsidiaries of intercompany Indebtedness between or among the Company and
     any of its Restricted Subsidiaries; provided, however, that:

              (A) if the Company or any Guarantor is the obligor on such
     Indebtedness, such Indebtedness must be expressly subordinated to the prior
     payment in full in cash of all Obligations with respect to the Notes, in
     the case of the Company, or the Guaranty of such Guarantor, in the case of
     a Guarantor; and

              (B) (1) any subsequent issuance or transfer of Equity Interests
     that results in any such Indebtedness being held by a Person other than the
     Company or a Restricted Subsidiary thereof and (2) any sale or other
     transfer of any such Indebtedness to a Person that is not either the
     Company or a Restricted Subsidiary thereof shall be deemed, in each case,
     to constitute an incurrence of such Indebtedness by the Company

                                       52
<PAGE>   58

     or such Restricted Subsidiary, as the case may be, that was not permitted
     by this clause (vi);

          (vii) the incurrence by the Company or any of its Restricted
     Subsidiaries of Hedging Obligations that are incurred for the purpose of
     fixing or hedging interest rate risk with respect to any floating rate
     Indebtedness that is permitted by the terms of this Indenture to be
     outstanding or to hedge exposure to foreign currency fluctuations or
     commodity price risk with respect to any commodity purchases;

          (viii) (A) the guarantee by the Company or any of the Guarantors of
     Indebtedness of the Company or a Guarantor that was permitted to be
     incurred by another provision of this Section 4.09; and

                 (B) the guarantee by any Restricted Subsidiary of the Company
     that is not a Guarantor of Indebtedness of another Restricted Subsidiary of
     the Company that is not a Guarantor that was permitted to be incurred by
     another provision of this Section 4.09;

          (ix) the accrual of interest, accretion or amortization of original
     issue discount, the payment of interest on any Indebtedness in the form of
     additional Indebtedness with the same terms, and the payment of dividends
     on Disqualified Stock in the form of additional shares of the same class of
     Disqualified Stock; provided, in each such case, that the amount thereof is
     included in Fixed Charges of the Company as accrued;

          (x) the incurrence by the Company or any of its Restricted
     Subsidiaries of additional Indebtedness or Disqualified Stock in an
     aggregate principal amount (or accreted value, as applicable) at any time
     outstanding, including all Permitted Refinancing Indebtedness incurred to
     refund, refinance or replace any Indebtedness incurred pursuant to this
     clause (x), not to exceed $50.0 million;

          (xi) the incurrence by the Company's Unrestricted Subsidiaries of
     Non-Recourse Debt, provided, however, that if any such Indebtedness ceases
     to be Non-Recourse Debt of an Unrestricted Subsidiary, such event shall be
     deemed to constitute an incurrence of Indebtedness by a Restricted
     Subsidiary of the Company that was not permitted by this clause (xi);

          (xii) the incurrence of Indebtedness (including letters of credit) in
     respect of workers' compensation claims, self-insurance obligations,
     performance, surety, bid or similar bonds and completion guaranties
     provided by the Company or one of its Restricted Subsidiaries in the
     ordinary course of business and consistent with past practices;

          (xiii) Indebtedness arising from agreements of the Company or a
     Restricted Subsidiary providing for indemnification, adjustment of purchase
     price, earn out or other similar obligations, in each case, incurred or
     assumed in connection with the disposition of any business, assets or a
     Restricted Subsidiary, other than guarantees of Indebtedness incurred by
     any Person acquiring all or any portion of such business, assets or
     Restricted Subsidiary for the purpose of financing such acquisition;
     provided that the maximum assumable liability in respect of all such
     Indebtedness shall at no time exceed the gross proceeds actually received
     by the Company and its Restricted Subsidiaries in connection with such
     disposition;

                                       53
<PAGE>   59

          (xiv) the incurrence by a Securitization Entity of Indebtedness in a
     Qualified Securitization Transaction that is Non-Recourse Debt (except for
     Standard Securitization Undertakings) with respect to the Company and its
     other Restricted Subsidiaries;

          (xv) Indebtedness of the Company evidenced by promissory notes
     subordinated to the Notes and the Exchange Notes issued to employees of the
     Company and its Subsidiaries in lieu of cash payment at any time for Equity
     Interest of DASI being repurchased from such employees; provided; that the
     aggregate amount of such Indebtedness does not exceed $5.0 million at any
     one time outstanding;

          (xvi) guaranties of Indebtedness of any other person incurred by the
     Company or a Restricted Subsidiary in the ordinary course of business in an
     aggregate principal amount not to exceed $5.0 million at any one time
     outstanding;

          (xvii) Indebtedness consisting of take-or-pay obligations contained in
     supply agreements entered into by the Company or its Subsidiaries in the
     ordinary course; and

          (xviii) Indebtedness of Restricted Subsidiaries that are not
     Guarantors permitted by Section 4.13 hereof.

          For purposes of determining compliance with this Section 4.09, in the
     event that an item of Indebtedness meets the criteria of more than one of
     the categories of Permitted Debt described in clauses (i) through (xvii)
     above, or is entitled to be incurred pursuant to the first paragraph of
     this Section 4.09, the Company shall, in its sole discretion, classify such
     item of Indebtedness in any manner that complies with this Section 4.09.
     All borrowings outstanding on the date of this Indenture under the Credit
     Facilities will be deemed to have been borrowed pursuant to clause (i) of
     the definition of Permitted Debt.

SECTION 4.10. Asset Sales.

          The Company shall not, and shall not permit any of its Restricted
     Subsidiaries to, consummate an Asset Sale unless:

          (i) the Company (or the Restricted Subsidiary, as the case may be)
     receives consideration at the time of such Asset Sale at least equal to the
     fair market value of the assets or Equity Interests issued or sold or
     otherwise disposed of (as determined in good faith by the Company);

          (ii) such fair market value is determined by the Company's Board of
     Directors and evidenced by a resolution of the Board of Directors set forth
     in an Officers' Certificate delivered to the Trustee; and

          (iii) at least 75% of the consideration therefor received by the
     Company or such Restricted Subsidiary is in the form of cash or Cash
     Equivalents. For purposes of this provision, each of the following shall be
     deemed to be cash:

               (A) any liabilities (as shown on the Company's or such Restricted
     Subsidiary's most recent balance sheet) of the Company or any Restricted
     Subsidiary

                                       54
<PAGE>   60

(other than contingent liabilities and liabilities that are by
     their terms subordinated to the Notes or any Guaranty) that are assumed by
     the transferee of any such assets pursuant to a customary novation
     agreement that releases the Company or such Restricted Subsidiary from
     further liability;

               (B) any securities, notes or other obligations received by the
     Company or any such Restricted Subsidiary from such transferee that are
     converted by the Company or such Restricted Subsidiary into cash within 180
     days after the consummation of such Asset Sale (to the extent of the cash
     received in that conversion); and

               (C) any Designated Noncash Consideration received by the Company
     or any of its Restricted Subsidiaries in such Asset Sale; provided that the
     aggregate fair market value (as determined above) of such Designated
     Noncash Consideration, taken together with the fair market value at the
     time of receipt of all other Designated Noncash Consideration received
     pursuant to this clause (c) less the amount of Net Proceeds previously
     realized in cash from prior Designated Noncash Consideration, is less than
     5.0% of Total Assets at the time of the receipt of such Designated Noncash
     Consideration (with the fair market value of each item of Designated
     Noncash Consideration being measured at the time received and without
     giving effect to subsequent changes in value).

          Within 365 days after the receipt of any Net Proceeds from an Asset
Sale, the Company may apply such Net Proceeds at its option:

          (i) to repay Senior Debt, and if such Senior Debt repaid is revolving
     credit Indebtedness, to correspondingly reduce commitments with respect
     thereto;

          (ii) to acquire all or substantially all of the assets of, or a
     majority of the Voting Stock of, another Permitted Business;

          (iii) to make a capital expenditure; and/or

          (iv) to acquire other long-term assets that are used or useful in a
     Permitted Business.

          Pending the final application of any such Net Proceeds, the Company
may temporarily reduce revolving credit borrowings or otherwise invest such Net
Proceeds in any manner that is not prohibited by this Indenture.

          Any Net Proceeds from Asset Sales that are not applied or invested as
provided in the preceding paragraph will constitute "Excess Proceeds." When the
aggregate amount of Excess Proceeds exceeds $20.0 million, the Company will make
an Asset Sale Offer to all Holders of Notes and all holders of other
Indebtedness that is pari passu with the Notes containing provisions similar to
those set forth in this Indenture with respect to offers to purchase or redeem
with the proceeds of sales of assets to purchase the maximum principal amount of
Notes and such other pari passu Indebtedness that may be purchased out of the
Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100%
of the principal amount plus accrued and unpaid interest and Liquidated Damages,
if any, to the date of purchase, and will be payable in cash. If any Excess
Proceeds remain after consummation of an Asset

                                       55
<PAGE>   61

Sale Offer, the Company may use such Excess Proceeds for any purpose not
otherwise prohibited by this Indenture. If the aggregate principal amount of
Notes and such other pari passu Indebtedness tendered into such Asset Sale Offer
exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and
such other pari passu Indebtedness to be purchased on a pro rata basis based on
the principal amount of Notes and such other pari passu Indebtedness tendered.
Upon completion of each Asset Sale Offer, the amount of Excess Proceeds shall be
reset at zero.

          The Company will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with each
repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the
provisions of any securities laws or regulations conflict with the Asset Sales
provisions of this Indenture, the Company will comply with the applicable
securities laws and regulations and will not be deemed to have breached its
obligations under the Asset Sale provisions of this Indenture by virtue of such
conflict.

SECTION 4.11. Transactions with Affiliates.

          The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise
dispose of any of its properties or assets to, or purchase any property or
assets from, or enter into or make or amend any transaction, contract,
agreement, understanding, loan, advance or guarantee with, or for the benefit
of, any Affiliate (each, an "Affiliate Transaction"), unless:

          (i) such Affiliate Transaction is on terms that are no less favorable
to the Company or the relevant Restricted Subsidiary than those that would have
been obtained in a comparable transaction by the Company or such Restricted
Subsidiary with an unrelated Person; and

          (ii) the Company delivers to the Trustee:

               (A) with respect to any Affiliate Transaction or series of
     related Affiliate Transactions involving aggregate consideration in excess
     of $5.0 million, a resolution of the Board of Directors set forth in an
     Officers' Certificate certifying that such Affiliate Transaction complies
     with this covenant and that such Affiliate Transaction has been approved by
     a majority of the disinterested members of the Board of Directors; and

               (B) with respect to any Affiliate Transaction or series of
     related Affiliate Transactions involving aggregate consideration in excess
     of $15.0 million, an opinion as to the fairness to the Company or the
     relevant Restricted Subsidiary of such Affiliate Transaction from a
     financial point of view issued by an accounting, appraisal or investment
     banking firm of national standing.

          The following items shall not be deemed to be Affiliate Transactions
     and, therefore, will not be subject to the provisions of the prior
     paragraph:

          (i) any employment agreement entered into by the Company or any of its
     Restricted Subsidiaries in the ordinary course of business and consistent
     with the past practice of the Company or such Restricted Subsidiary;

                                       56
<PAGE>   62

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

          (iii) payment of reasonable directors fees to Persons who are not
otherwise Affiliates of the Company;

          (iv) sales of Equity Interests (other than Disqualified Stock) to
Affiliates of the Company;

          (v) Restricted Payments that are permitted by the provisions of this
Indenture described in Section 4.07 hereof;

          (vi) providing indemnity to officers, directors, or employees of the
Company or any of its Subsidiaries as determined in good faith by the Board of
Directors of the Company;

          (vii) the payment of customary management, consulting and advisory
fees and related expenses to Hidden Creek or its affiliates consistent with past
practices, including, without limitation, in connection with acquisitions,
divestitures or financings by DASI, the Company or any of the Company's
Restricted Subsidiaries;

          (viii) the existence of, or the performance by the Company or any of
its Restricted Subsidiaries of its obligations under the terms of, any agreement
to which it is a party as of the date of this Indenture, and any similar
agreements which it may enter into thereafter; provided, however, that the
existence of, or the performance by the Company or any of its Restricted
Subsidiaries of obligations under, any future amendment to any such existing
agreement or under any similar agreement entered into after the date of this
Indenture shall only be permitted by this clause to the extent that the terms of
any such amendment or similar agreement are not disadvantageous to the Holders
in any material respect;

          (ix) transactions effected as part of a Qualified Securitization
Transaction;

          (x) transactions with customers, joint venture partners, clients and
suppliers, in each case in the ordinary course of business and otherwise in
compliance with the terms of this Indenture which are fair to the Company or its
Restricted Subsidiaries, in the reasonable determination of the Board of
Directors of the Company;

          (xi) the grant of stock options, restricted stock or similar rights to
the Company's employees, directors and consultants pursuant to plans approved by
the Board of Directors of the Company; and

          (xii) loans or advances to employees or consultants in the ordinary
course of business and consistent with past practices, which are approved by a
majority of the Board of Directors of the Company in good faith.

SECTION 4.12. Liens.

          The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly, create, incur, assume or suffer to
exist any Lien of any kind on any asset now owned or hereafter acquired, except
Permitted Liens.

                                       57
<PAGE>   63

SECTION 4.13. Limitation on Foreign Indebtedness.

          The Company shall not permit any Restricted Subsidiary of the Company
that is not a Guarantor to, directly or indirectly, incur any Indebtedness
(including Acquired Indebtedness) unless:

          (i) after giving effect to the incurrence of such Indebtedness and the
     receipt of the application of the proceeds thereof;

               (A) if, as a result of the incurrence of such Indebtedness such
     Restricted Subsidiary will become subject to any restriction or limitation
     on the payment of dividends or the making of other distributions,

               (1) the Fixed Charge Coverage Ratio of Restricted Subsidiaries
          that are not Guarantors (determined on a pro forma basis for the last
          four fiscal quarters for which financial statements are available at
          the date of determination) is greater than 2.5 to 1; and

               (2) the Company's Fixed Charge Coverage Ratio (determined on a
          pro forma basis for the last four fiscal quarters of the Company for
          which financial statements are available at the date of determination)
          is greater than 2.0 to 1; and

               (B) in any other case, the Company's Fixed Charge Coverage Ratio
     (determined on a pro forma basis for the last four fiscal quarters of the
     Company for which financial statements are available at the date of
     determination) is greater than 2.0 to 1; and

          (ii) no Default or Event of Default shall have occurred and be
     continuing at the time or as a consequence of the incurrence of such
     Indebtedness.

          In the event that any Indebtedness incurred pursuant to clause (1)(b)
of the foregoing paragraph is proposed to be amended, modified or otherwise
supplemented such that the payment of dividends or the making of other
distributions becomes subject in any manner to any restriction or limitation,
the Company will not permit the Restricted Subsidiary to so amend, modify or
supplement such Indebtedness unless such Indebtedness could be incurred pursuant
to the terms of clause (1)(a) of the foregoing paragraph.

          All calculations required under the prior two paragraphs hereof shall
be made in a manner consistent with the calculations required under Section
4.09.

SECTION 4.14. Corporate Existence.

          Subject to Article 5 hereof, the Company shall do or cause to be done
all things necessary to preserve and keep in full force and effect (i) its
corporate existence, and the corporate, partnership or other existence of each
of its Subsidiaries, in accordance with the respective organizational documents
(as the same may be amended from time to time) of the Company or any such
Subsidiary and (ii) the rights (charter and statutory), licenses and franchises
of the Company and its Subsidiaries; provided, however, that the Company shall
not be required to preserve any such right, license or franchise, or the
corporate, partnership or other existence of any of its Subsidiaries, if the

                                       58
<PAGE>   64

Board of Directors shall determine that the preservation thereof is no longer
desirable in the conduct of the business of the Company and its Subsidiaries,
taken as a whole, and that the loss thereof is not adverse in any material
respect to the Holders of the Notes.

SECTION 4.15. Offer to Repurchase Upon Change of Control.

          If a Change of Control occurs, each Holder of Notes will have the
right to require the Company to repurchase all or any part (equal to $1,000 or
an integral multiple thereof) of that Holder's Notes pursuant to the offer
described below (the "Change of Control Offer"). In the Change of Control Offer,
the Company shall offer a Change of Control Payment in cash equal to 101% of the
aggregate principal amount of Notes repurchased plus accrued and unpaid interest
and Liquidated Damages thereon, if any, to the date of purchase (the "Change of
Control Payment"). Within 30 days following any Change of Control, unless the
Company has exercised its right to redeem the Notes pursuant to Section 3.07,
the Company shall mail a notice to the Trustee and each Holder describing the
transaction or transactions that constitute the Change of Control and offering
to repurchase Notes on the purchase date specified in such notice (which must be
no earlier than 30 days nor later than 60 days from the date such notice is
mailed, other than as required by law (the "Change of Control Payment Date")),
pursuant to the procedures required by this Indenture and described in such
notice. The Company shall comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the
repurchase of the Notes as a result of a Change of Control. To the extent that
the provisions of any securities laws or regulations conflict with the Change of
Control provisions of this Indenture, the Company will comply with the
applicable securities laws and regulations and will not be deemed to have
breached its obligations under the Change of Control provisions of this
Indenture by virtue of such conflict.

          On the Change of Control Payment Date, the Company shall, to the
extent lawful:

          (i) accept for payment all Notes or portions thereof properly tendered
     pursuant to the Change of Control Offer;

          (ii) deposit with the Paying Agent an amount equal to the Change of
     Control Payment in respect of all Notes or portions thereof so tendered;
     and

          (iii) deliver or cause to be delivered to the Trustee the Notes so
     accepted together with an Officers' Certificate stating the aggregate
     principal amount of Notes or portions thereof being purchased by the
     Company.

          The Paying Agent shall promptly mail to each Holder of Notes so
tendered the Change of Control Payment for such Notes, and the Trustee shall
promptly authenticate and mail (or cause to be transferred by book entry) to
each Holder a new Note equal in principal amount to any unpurchased portion of
the Notes surrendered, if any; provided that each such new Note shall be in a
principal amount of $1,000 or an integral multiple thereof.

          Prior to complying with any of the provisions of this Section 4.15,
but in any event within 90 days following a Change of Control, the Company will
either repay all outstanding Senior Debt or obtain the requisite consents, if
any, under all agreements governing outstanding Senior Debt to

                                       59
<PAGE>   65

permit the repurchase of Notes required by this covenant. If the Company does
not obtain such consents or repay such borrowings, the Company will be
prohibited from purchasing the Notes. The Company will publicly announce the
results of the Change of Control Offer on or as soon as practicable after the
Change of Control Payment Date.

          The Company shall not be required to make a Change of Control Offer
upon a Change of Control if a third party makes the Change of Control Offer in
the manner, at the times and otherwise in compliance with the requirements set
forth in this Section 4.15 and Section 3.09 hereof and purchases all Notes
validly tendered and not withdrawn under such Change of Control Offer.

SECTION 4.16. No Senior Subordinated Debt.

          The Company shall not incur, create, issue, assume, guarantee or
otherwise become liable for any Indebtedness that is subordinate or junior in
right of payment to any Indebtedness of the Company and senior in any respect in
right of payment to the Notes. No Guarantor shall incur, create, issue, assume,
guarantee or otherwise become liable for any Indebtedness that is subordinate or
junior in right of payment to any Indebtedness of such Guarantor and senior in
any respect in right of payment to such Guarantor's Guaranty.

SECTION 4.17. Additional Subsidiary Guaranties.

          If the Company or any of its Restricted Subsidiaries acquires or
creates another material Domestic Restricted Subsidiary after the date of this
Indenture and the newly acquired or created material Domestic Restricted
Subsidiary guarantees any obligations under any Credit Facility, then that newly
acquired or created Domestic Restricted Subsidiary must become a Guarantor and
execute a supplemental indenture and deliver an Opinion of Counsel to the
Trustee within 10 Business Days of the date on which it guaranteed any
obligation under any of the Credit Facilities. If any Subsidiary that is not a
Guarantor at any time guaranties Indebtedness of the Company or a Guarantor, the
Company will cause such Subsidiary to simultaneously execute and deliver
supplemental indentures providing for the Guaranty of the payment of the Notes
by such Subsidiary.

SECTION 4.18. Designation of Restricted and Unrestricted Subsidiaries.

          The Board of Directors may designate any Restricted Subsidiary to be
an Unrestricted Subsidiary if that designation would not cause a Default. If a
Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate
fair market value of all outstanding Investments owned by the Company and its
Restricted Subsidiaries in the Subsidiary so designated shall be deemed to be an
Investment made as of the time of such designation and shall either reduce the
amount available for Restricted Payments under clause (iii)(B) of the first
paragraph of Section 4.07 hereof or reduce the amount available for future
Investments, as the Company shall determine. That designation shall only be
permitted if such Investment would be permitted at the time and if such
Restricted Subsidiary otherwise meets the definition of an Unrestricted
Subsidiary. The Board of Directors may redesignate any Unrestricted Subsidiary
to be a Restricted Subsidiary if the redesignation would not cause a Default.

SECTION 4.19. Payments for Consent.

          The Company and DASI will not, and will not permit any of their
Subsidiaries to, directly or indirectly, pay or cause to be paid any
consideration to or for the benefit of any Holder of

                                       60
<PAGE>   66

Notes for or as an inducement to any consent, waiver or amendment of any of the
terms or provisions of this Indenture or the Notes issued thereunder unless such
consideration is offered to be paid and is paid to all Holders of such Notes
that consent, waive or agree to amend in the time frame set forth in the
solicitation documents relating to such consent, waiver or agreement.

merge with or into another Person (whether or not the Company is the surviving
corporation); or (2) sell, assign, transfer, convey or otherwise dispose of all
or substantially all of the properties or assets of the Company and its

     limited liability company or trust organized or existing under the laws of
     the United States, any state thereof or the District of Columbia;

          (ii) the Person formed by or surviving any such consolidation or
     merger (if other than the Company) or the Person to which such sale,

     assumes all the obligations of the Company under the Notes, this Indenture
     and the Registration Rights Agreement pursuant to agreements reasonably
     satisfactory to the Trustee;

          (iii) immediately after such transaction no Default or Event of
     Default exists; and

          (iv) the Company or the Person formed by or surviving any such
     consolidation or merger (if other than the Company) or to which such sale,
     assignment, transfer, conveyance or other disposition shall have been made
     shall, on the date of such transaction after giving pro forma effect
     thereto and any related financing transactions as if the same had occurred
     at the beginning of the applicable four-quarter period, be permitted to
     incur at least $1.00 of additional Indebtedness pursuant to the Fixed
     Charge Coverage Ratio test set forth in the first paragraph of Section 4.09
     hereof.

apply to a sale, assignment, transfer, conveyance or other disposition of assets
between or among the Company and any Guarantor.

SECTION 5.02. Successor Corporation Substituted.

          Upon any consolidation or merger, or any sale, assignment, transfer,
conveyance or other disposition of all or substantially all of the assets of the
Company in accordance with Section 5.01 hereof, the successor corporation formed
by such consolidation or into or with which the Company is merged or to which
such sale, assignment, transfer, conveyance or other disposition is made shall

                                       61
<PAGE>   67

succeed to, and be substituted for (so that from and after the date of such
consolidation, merger, sale, conveyance or other disposition, the provisions of
this Indenture referring to the "Company" shall refer instead to the successor
corporation and not to the Company), and may exercise every right and power of
the Company under this Indenture with the same effect as if such successor
Person had been named as the Company herein; provided, however, that the
predecessor Company shall not be relieved from the obligation to pay the
principal of and interest on the Notes except in the case of a sale of all of
the Company's assets that meets the requirements of Section 5.01 hereof.

                              DEFAULTS AND REMEDIES

SECTION 6.01. Events of Default.

          Each of the following is an Event of Default:

          (i) default for 30 days in the payment when due of interest on, or
     Liquidated Damages with respect to, any Notes, whether or not prohibited by
     Article 10 hereof;

          (ii) default in payment when due of the principal of or premium, if
     any, on the Notes, whether or not prohibited by Article 10 hereof;

     60 days after specified notice to comply with any of the other agreements
     in this Indenture or the Notes;

          (v) default under any mortgage, indenture or instrument under which
     there is issued and outstanding any Indebtedness for money borrowed by the
     Company or any of its Restricted Subsidiaries (or the payment of which is
     guaranteed by the Company or any of its Restricted Subsidiaries) whether
     such Indebtedness or guarantee now exists, or is created after the date
     hereof, if that default:

               (A) is caused by a failure to pay principal of, or interest or
     premium, if any, on such Indebtedness prior to the expiration of the grace
     period provided in such Indebtedness on the date of such default (a
     "Payment Default"); or

               (B) results in the acceleration of such Indebtedness prior to its
     express maturity,

and, in each case, the principal amount of any such Indebtedness, together with
the principal amount of any other such Indebtedness under which there has been a
Payment Default or the maturity of which has been so accelerated, aggregates
$20.0 million or more;

          (vi) failure by the Company or any of its Restricted Subsidiaries to
     pay final judgments aggregating in excess of $20.0 million, which judgments
     are not paid, vacated, discharged or stayed or non-appealable for a period
     of 60 days and in the event such judgment is

                                       62
<PAGE>   68

     covered by insurance, an enforcement proceeding has been commenced by any
     creditor upon such judgment or decree which is not properly stayed;

          (vii) the Company or any of its Significant Subsidiaries or any group
     of Subsidiaries that, taken as a whole, would constitute a Significant
     Subsidiary pursuant to or within the meaning of 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 all
     or substantially all of its property;

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

               (E) generally is not paying its debts as they become due; or

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

               (A) is for relief against the Company or any of its Significant
     Subsidiaries or any group of Subsidiaries that, taken as a whole, would
     constitute a Significant Subsidiary in an involuntary case;

               (B) appoints a custodian of the Company or any of its Significant
     Subsidiaries or any group of Subsidiaries that, taken as a whole, would
     constitute a Significant Subsidiary or for all or substantially all of the
     property of the Company or any of its Significant Subsidiaries or any group
     of Subsidiaries that, taken as a whole, would constitute a Significant
     Subsidiary; or

               (C) orders the liquidation of the Company or any of its
     Significant Subsidiaries or any group of Subsidiaries that, taken as a
     whole, would constitute a Significant Subsidiary;

               and the order or decree remains unstayed and in effect for 60
     consecutive days; or

          (ix) except as permitted by this Indenture, any Guaranty is held in
     any judicial proceeding to be unenforceable or invalid or shall cease for
     any reason to be in full force and effect or any Guarantor, or any Person
     acting on behalf of any Guarantor, shall deny or disaffirm its obligations
     under such Guarantor's Guaranty.

SECTION 6.02. Acceleration.

          If any Event of Default (other than an Event of Default specified in
clause (vii) or (viii) of Section 6.01 hereof with respect to the Company, any
Significant Subsidiary or any group of Subsidiaries that, taken as a whole,
would constitute a Significant Subsidiary) occurs and is continuing,

                                       63
<PAGE>   69

the Trustee or the Holders of at least 25% in principal amount of the then
outstanding Notes may declare the principal of and accrued interest on all the
Notes to be due and payable by notice in writing to the Company and the Trustee
specifying the respective Event of Default and that such notice is a "notice of
acceleration" (the "Acceleration Notice"), and the same (1) shall become
immediately due and payable or (2) if there are any amounts outstanding under
the Credit Agreement, shall become immediately due and payable upon the first to
occur of an acceleration under the Credit Agreement or five Business Days after
receipt by the Company and the Representative under the Credit Agreement of such
Acceleration Notice but only if such Event of Default is then continuing. Upon
any such declaration, but subject to the immediately preceding sentence, the
Notes shall become due and payable immediately. Notwithstanding the foregoing,
if an Event of Default specified in clause (vii) or (viii) of Section 6.01
hereof occurs with respect to the Company, all outstanding Notes shall be due
and payable immediately without further action or notice. The Holders of a
majority in aggregate principal amount of the then outstanding Notes by written
notice to the Trustee may on behalf of all of the Holders rescind an
acceleration and its consequences if the rescission would not conflict with any
judgment or decree and if all existing Events of Default (except nonpayment of
principal, interest or premium that has become due solely because of the
acceleration) have been cured or waived.

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, premium, if
any, and interest and Liquidated Damages, if any, on the Notes or to enforce the
performance of any provision of the Notes or this Indenture.

          The Trustee may maintain a proceeding even if it does not possess any
of the Notes or does not produce any of them in the proceeding. A delay or
omission by the Trustee or any Holder of a Note 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. All remedies are
cumulative to the extent permitted by law.

SECTION 6.04. Waiver of Past Defaults.

          Holders of not less than a majority in aggregate principal amount of
the then outstanding Notes by notice to the Trustee may on behalf of the Holders
of all of the Notes waive an existing Default or Event of Default and its
consequences hereunder, except a continuing Default or Event of Default in the
payment of the principal of, premium and Liquidated Damages, if any, or interest
on, the Notes (including in connection with an offer to purchase) (provided,
however, that the Holders of a majority in aggregate principal amount of the
then outstanding Notes may rescind an acceleration and its consequences,
including any related payment default that resulted from such acceleration).
Upon any such waiver, such Default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured for every purpose
of this Indenture; but no such waiver shall extend to any subsequent or other
Default or impair any right consequent thereon.

SECTION 6.05. Control by Majority.

          Holders of a majority in principal amount of the then outstanding
Notes may direct the time, method and place of conducting any proceeding for
exercising any remedy available to the Trustee or exercising any trust or power
conferred on it. However, the Trustee may refuse to follow any

                                       64
<PAGE>   70

direction that conflicts with law or this Indenture that the Trustee determines
may be unduly prejudicial to the rights of other Holders of Notes or that may
involve the Trustee in personal liability.

SECTION 6.06. Limitation on Suits.

          A Holder of a Note may pursue a remedy with respect to this Indenture
or the Notes only if:

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

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

               (c) such Holder of a Note or Holders of Notes offer and, if
     requested, provide to the Trustee indemnity satisfactory to the Trustee
     against any loss, liability or expense;

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

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

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

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

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

SECTION 6.08.  Collection Suit by Trustee.

          If an Event of Default specified in Section 6.01(i) or (ii) occurs and
is continuing, the Trustee is authorized to recover judgment in its own name and
as trustee of an express trust against the Company for the whole amount of
principal of, premium and Liquidated Damages, if any, and interest remaining
unpaid on the Notes and interest on overdue principal and, to the extent lawful,
interest and such further amount as shall be sufficient to cover the costs and
expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel.

SECTION 6.09. Trustee May File Proofs of Claim.

          The Trustee is authorized to file such proofs of claim and other
papers or documents as may be necessary or advisable in order to have the claims
of the Trustee (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel)

                                       65
<PAGE>   71

and the Holders of the Notes allowed in any judicial proceedings relative to the
Company (or any other obligor upon the Notes), its creditors or its property and
shall be entitled and empowered to collect, receive and distribute any money or
other property payable or deliverable on any such claims and any custodian in
any such judicial proceeding is hereby authorized by each Holder to make such
payments to the Trustee, and in the event that the Trustee shall consent to the
making of such payments directly to the Holders, to pay to the Trustee any
amount due to it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, and any other amounts due the
Trustee under Section 7.07 hereof. To the extent that the payment of any such
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section 7.07 hereof out
of the estate in any such proceeding, shall be denied for any reason, payment of
the same shall be secured by a Lien on, and shall be paid out of, any and all
distributions, dividends, money, securities and other properties that the
Holders may be entitled to receive in such proceeding whether in liquidation or
under any plan of reorganization or arrangement or otherwise. Nothing herein
contained shall be deemed to authorize the Trustee to authorize or consent to or
accept or adopt on behalf of any Holder any plan of reorganization, arrangement,
adjustment or composition affecting the Notes or the rights of any Holder, or to
authorize the Trustee to vote in respect of the claim of any Holder in any such
proceeding.

SECTION 6.10. Priorities.

          If the Trustee collects any money pursuant to this Article, it shall
pay out the money in the following order:

          First: to the Trustee, its agents and attorneys for amounts due under
Section 7.07 hereof, including payment of all compensation, expense and
liabilities incurred, and all advances made, by the Trustee and the costs and
expenses of collection;

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

          Third: to the Company or to such party as a court of competent
jurisdiction shall direct.

          The Trustee may fix a record date and payment date for any payment to
Holders of Notes pursuant to this Section 6.10.

SECTION 6.11. Undertaking for Costs.

          In any suit for the enforcement of any right or remedy under this
Indenture or in any suit against the Trustee for any action taken or omitted by
it as a Trustee, a court in its discretion may require the filing by any party
litigant in the suit of an undertaking to pay the costs of the suit, and the
court in its discretion may assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in the suit, having due regard to
the merits and good faith of the claims or defenses made by the party litigant.
This Section does not apply to a suit by the Trustee, a suit by a Holder of a
Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in
principal amount of the then outstanding Notes.

                                     TRUSTEE

SECTION 7.01. Duties of Trustee.

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

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

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

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

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

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

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

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

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

               (e) No provision of this Indenture shall require the Trustee to
     expend or risk its own funds or incur any liability. The Trustee shall be
     under no obligation to exercise any of its rights and powers under this
     Indenture at the request of any Holders, unless such Holder shall have
     offered to the Trustee security and indemnity satisfactory to it against
     any loss, liability or expense.

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

SECTION 7.02. Rights of Trustee.

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

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

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

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

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

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

     (g) 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, 6.01(i) or 6.01(ii) or (ii) any Default or
Event of Default of which the Trustee shall have received written notification
or obtained actual knowledge.

     (h) Delivery of reports, information and documents to the Trustee under
Section 4.03 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 Notes and may otherwise deal with the Company or any
Affiliate of the Company with the same rights it would have if it were not
Trustee. However, in the event that the Trustee acquires any conflicting
interest it must eliminate such conflict within 90 days, apply to the SEC for
permission to continue as trustee or resign. Any Agent may do the same with like
rights and duties. The Trustee is also subject to Sections 7.10 and 7.11 hereof.

                                       68
<PAGE>   74

SECTION 7.04. Trustee's Disclaimer.

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

SECTION 7.05. Notice of Defaults.

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

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

          Within 60 days after each November 1 beginning with the November 1
following the date of this Indenture, and for so long as Notes remain
outstanding, the Trustee shall mail to the Holders of the Notes a brief report
dated as of such reporting date that complies with TIA ss. 313(a) (but if no
event described in TIA ss. 313(a) has occurred within the twelve months
preceding the reporting date, no report need be transmitted). The Trustee also
shall comply with TIA ss. 313(b)(2). The Trustee shall also transmit by mail all
reports as required by TIA ss. 313(c).

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

SECTION 7.07. Compensation and Indemnity.

          The Company and the Guarantors shall pay to the Trustee from time to
time reasonable compensation for its acceptance of this Indenture and services
hereunder. The Trustee's compensation shall not be limited by any law on
compensation of a trustee of an express trust. The Company and the Guarantors
shall reimburse the Trustee promptly upon request for all reasonable
disbursements, advances and expenses incurred or made by it in addition to the
compensation for its services. Such expenses shall include the reasonable
compensation, disbursements and expenses of the Trustee's agents and counsel.

          The Company and the Guarantors shall, jointly and severally, indemnify
the Trustee against any and all losses, liabilities or expenses incurred by it
arising out of or in connection with the acceptance or administration of its
duties under this Indenture, including the costs and expenses of enforcing this
Indenture against the Company and the Guarantors (including this Section 7.07)
and defending itself against any claim (whether asserted by the Company or any
Holder or any other person) or liability in connection with the exercise or
performance of any of its powers or duties hereunder,

                                       69
<PAGE>   75

except to the extent any such loss, liability or expense may be attributable to
its negligence or bad faith. The Trustee shall notify the Company and the
Guarantors promptly of any claim for which it may seek indemnity. Failure by the
Trustee to so notify the Company shall not relieve the Company of its
obligations hereunder. The Company shall defend the claim and the Trustee shall
cooperate in the defense. The Trustee may have separate counsel and the Company
shall pay the reasonable fees and expenses of such counsel. The Company and the
Guarantors need not pay for any settlement made without its consent, which
consent shall not be unreasonably withheld.

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

          When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 6.01(vii) or (viii) hereof occurs, the expenses and
the compensation for the services (including the fees and expenses of its agents
and counsel) are intended to constitute expenses of administration under any
Bankruptcy Law.

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

          The Company's and the Guarantors' obligations under this Section 7.07
and any claim arising hereunder shall survive the resignation or removal of any
Trustee, the discharge of the Company's obligations pursuant to Article 8 hereof
and any rejection or termination under any Bankruptcy Law.

SECTION 7.08. Replacement of Trustee.

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

          The Trustee may resign in writing at any time and be discharged from
the trust hereby created by so notifying the Company. The Holders of Notes of a
majority in principal amount of the then outstanding Notes may remove the
Trustee by so notifying the Trustee and the Company in writing. The Company may
remove the Trustee if:

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

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

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

     (d) the Trustee becomes incapable of acting.

                                       70
<PAGE>   76

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

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

     If the Trustee, after written request by any Holder of a Note who has been
a Holder of a Note for at least six months, fails to comply with Section 7.10,
such Holder of a Note may petition any court of competent jurisdiction for the
removal of the Trustee and the appointment of 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
Holders of the Notes. The retiring Trustee shall promptly transfer all property
held by it as Trustee to the successor Trustee, provided all sums owing to the
Trustee hereunder have been paid and subject to the Lien provided for in Section
7.07 hereof. Notwithstanding replacement of the Trustee pursuant to this Section
7.08, the Company's obligations under Section 7.07 hereof shall continue for the
benefit of the retiring Trustee.

SECTION 7.09. Successor Trustee by Merger, etc.

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

SECTION 7.10. Eligibility; Disqualification.

     There shall at all times be a Trustee hereunder that is a corporation
organized and doing business under the laws of the United States of America or
of any state thereof that is authorized under such laws to exercise corporate
trustee power, that is subject to supervision or examination by federal or state
authorities and that has a combined capital and surplus of at least $100.0
million or be part of a bank holding company with a combined capital and surplus
of at least $100 million, as set forth in its most recent published annual
report of condition.

     This Indenture shall always have a Trustee who satisfies the requirements
of TIA ss. 310(a)(1), (2) and (5). The Trustee is subject to TIA ss. 310(b).

SECTION 7.11. Preferential Collection of Claims Against Company.

     The Trustee is subject to TIA ss. 311(a), excluding any creditor
relationship listed in TIA ss. 311(b). A Trustee who has resigned or been
removed shall be subject to TIA ss. 311(a) to the extent indicated therein.

                                   ARTICLE 8.
                    LEGAL DEFEASANCE AND COVENANT DEFEASANCE

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

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

SECTION 8.02. Legal Defeasance and Discharge.

          Upon the Company's exercise under Section 8.01 hereof of the option
applicable to this Section 8.02, the Company shall, subject to the satisfaction
of the conditions set forth in Section 8.04 hereof, be deemed to have been
discharged from its obligations with respect to all outstanding Notes and all
obligations of the Guarantors shall be deemed to have been discharged with
respect to their obligations under the Guaranties on the date the conditions set
forth below are satisfied (hereinafter, "Legal Defeasance"). For this purpose,
Legal Defeasance means that the Company shall be deemed to have paid and
discharged the entire Indebtedness represented by the outstanding Notes and
Guaranties, respectively, and all obligations of the Guarantors shall be deemed
to have been discharged with respect to their obligations under the Guaranties,
which shall thereafter be deemed to be "outstanding" only for the purposes of
Section 8.05 hereof and the other Sections of this Indenture referred to in (a)
and (b) below, and to have satisfied all its other obligations under such Notes
and this Indenture (and the Trustee, on demand of and at the expense of the
Company, shall execute proper instruments acknowledging the same), except for
the following provisions which shall survive until otherwise terminated or
discharged hereunder: (a) the rights of Holders of outstanding Notes to receive
solely from the trust fund described in Section 8.04 hereof, and as more fully
set forth in such Section, payments in respect of the principal of, premium, if
any, and interest and Liquidated Damages, if any, on such Notes when such
payments are due, (b) the Company's obligations with respect to such Notes under
Article 2 and Section 4.02 hereof, (c) the rights, powers, trusts, duties and
immunities of the Trustee hereunder and the Company's and the Guarantors'
obligations in connection therewith and (d) this Article Eight. Subject to
compliance with this Article Eight, the Company may exercise its option under
this Section 8.02 notwithstanding the prior exercise of its option under Section
8.03 hereof.

SECTION 8.03. Covenant Defeasance.

          Upon the Company's exercise under Section 8.01 hereof of the option
applicable to this Section 8.03, the Company and each of the Guarantors shall,
subject to the satisfaction of the conditions set forth in Section 8.04 hereof,
be released from their respective obligations under the covenants contained in
Sections 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.15, 4.16, 4.17 and 4.18
hereof and clauses (iii) and (iv) of Section 5.01 hereof with respect to the
outstanding Notes on and after the date the conditions set forth in Section 8.04
are satisfied (hereinafter, "Covenant Defeasance"), and the Notes shall
thereafter be deemed not "outstanding" for the purposes of any direction,
waiver, consent or declaration or act of Holders (and the consequences of any
thereof) in connection with such covenants, but shall continue to be deemed
"outstanding" for all other purposes hereunder (it being understood that such
Notes shall not be deemed outstanding for accounting purposes). For this
purpose, Covenant Defeasance means that, with respect to the outstanding Notes,
the Company may omit to comply with and shall have no liability in respect of
any term, condition or limitation set forth in any such covenant,

                                       72
<PAGE>   78

whether directly or indirectly, by reason of any reference elsewhere herein to
any such covenant or by reason of any reference in any such covenant to any
other provision herein or in any other document and such omission to comply
shall not constitute a Default or an Event of Default under Section 6.01 hereof,
but, except as specified above, the remainder of this Indenture and such Notes
shall be unaffected thereby. In addition, upon the Company's exercise under
Section 8.01 hereof of the option applicable to this Section 8.03 hereof,
subject to the satisfaction of the conditions set forth in Section 8.04 hereof,
Sections 5.01(iii) and 5.01(iv) and Sections 6.01(iv) through 6.01(vi) hereof
shall not constitute Events of Default.

SECTION 8.04. Conditions to Legal or Covenant Defeasance.

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

In order to exercise either Legal Defeasance or Covenant Defeasance:

     (a) the Company must irrevocably deposit with the Trustee, in trust, for
the benefit of the Holders, cash in United States dollars, non-callable
Government Securities, or a combination thereof, in such amounts as will be
sufficient, in the opinion of a nationally recognized firm of independent public
accountants, to pay the principal of, premium, if any, and interest and
Liquidated Damages, if any on the outstanding Notes on the stated maturity or on
the applicable redemption date, as the case may be and the Company must specify
whether the Notes are being defeased to maturity or to a particular redemption
date;

     (b) in the case of an election under Section 8.02 hereof, the Company shall
have delivered to the Trustee an Opinion of Counsel in the United States
reasonably acceptable to the Trustee confirming 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 Holders of the
outstanding Notes will not recognize income, gain or loss for federal income tax
purposes as a result of such Legal Defeasance and will be subject to federal
income tax on the same amounts, in the same manner and at the same times as
would have been the case if such Legal Defeasance had not occurred;

     (c) in the case of an election under Section 8.03 hereof, the Company shall
have delivered to the Trustee an Opinion of Counsel in the United States
reasonably acceptable to the Trustee confirming that the Holders of the
outstanding Notes will not recognize income, gain or loss for federal income tax
purposes as a result of such Covenant Defeasance and will be subject to federal
income tax on the same amounts, in the same manner and at the same times as
would have been the case if such Covenant Defeasance had not occurred;

     (d) no Default or Event of Default shall have occurred and be continuing on
the date of such deposit (other than a Default or Event of Default resulting
from the incurrence of Indebtedness all or a portion of the proceeds of which
will be used to defease the Notes pursuant to this Article Eight concurrently
with such incurrence) or insofar as Sections 6.01(vii) or 6.01(viii) hereof is
concerned, at any time in the period ending on the 91st day after the date of
deposit;

                                       73
<PAGE>   79

     (e) such Legal Defeasance or Covenant Defeasance shall not result in a
breach or violation of, or constitute a default under the Senior Credit
Facilities or any other material agreement or instrument (other than this
Indenture) to which the Company or any of its Subsidiaries is a party or by
which the Company or any of its Subsidiaries is bound;

     (f) the Company shall have delivered to the Trustee an Opinion of Counsel
(which may be subject to customary exceptions) to the effect that, assuming no
intervening bankruptcy of the Company or any Guarantor between the date of
deposit and the 91st day following the deposit and assuming that no Holder is an
"insider" of the Company under applicable bankruptcy law, after the 91st day
following the deposit, the trust funds will not be subject to the effect of any
applicable bankruptcy, insolvency, reorganization or similar laws affecting
creditors' rights generally;

     (g) the Company shall have delivered to the Trustee an Officers'
Certificate stating that the deposit was not made by the Company with the intent
of preferring the Holders over any other creditors of the Company or with the
intent of defeating, hindering, delaying or defrauding any other creditors of
the Company; and

     (h) the Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent provided for or relating to the Legal Defeasance or the Covenant
Defeasance have been complied with.

SECTION 8.05. Deposited Money and Government Securities to be Held in Trust;
Other Miscellaneous Provisions.

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

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

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

                                       74
<PAGE>   80
SECTION 8.06. Repayment to Company.

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

SECTION 8.07. Reinstatement.

          If the Trustee or Paying Agent is unable to apply any United States
dollars or non-callable Government Securities in accordance with Section 8.02 or
8.03 hereof, as the case may be, by reason of any order or judgment of any court
or governmental authority enjoining, restraining or otherwise prohibiting such
application, then the Company's obligations under this Indenture and the Notes
shall be revived and reinstated as though no deposit had occurred pursuant to
Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is
permitted to apply all such money in accordance with Section 8.02 or 8.03
hereof, as the case may be; provided, however, that, if the Company makes any
payment of principal of, premium, if any, or interest on any Note following the
reinstatement of its obligations, the Company shall be subrogated to the rights
of the Holders of such Notes to receive such payment from the money held by the
Trustee or Paying Agent.

                                   ARTICLE 9.
                        AMENDMENT, SUPPLEMENT AND WAIVER

SECTION 9.01. Without Consent of Holders of Notes.

          Notwithstanding Section 9.02 of this Indenture, the Company, the
Guarantors and the Trustee may amend or supplement this Indenture or the Notes
without the consent of any Holder of a Note:

          (a) to cure any ambiguity, defect or inconsistency;

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

          (c) to provide for the assumption of the Company's obligations to the
Holders of the Notes by a successor to the Company or a Guarantor pursuant to
Article 5 hereof;

          (d) to make any change that would provide any additional rights or
benefits to the Holders of the Notes or that does not adversely affect the legal
rights hereunder of any Holder of the Note;

          (e) to comply with requirements of the SEC in order to effect or
maintain the qualification

                                       75
<PAGE>   81

of this Indenture under the TIA;

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

          (g) to allow any Guarantor to execute a supplemental indenture and/or
a Guaranty with respect to the Notes.

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

SECTION 9.02. With Consent of Holders of Notes.

          Except as provided below in this Section 9.02, the Company and the
Trustee may amend or supplement this Indenture (including Section 3.09, 4.10 and
4.15 hereof), the Guaranties and the Notes with the consent of the Holders of at
least a majority in principal amount of the Notes (including Additional Notes,
if any) then outstanding voting as a single class (including consents obtained
in connection with a tender offer or exchange offer for, or purchase of, the
Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or
Event of Default (other than a Default or Event of Default in the payment of the
principal of, premium, if any, or interest on the Notes, except a payment
default resulting from an acceleration that has been rescinded) or compliance
with any provision of this Indenture, the Guaranties or the Notes may be waived
with the consent of the Holders of a majority in principal amount of the then
outstanding Notes (including Additional Notes, if any) voting as a single class
(including consents obtained in connection with a tender offer or exchange offer
for, or purchase of, the Notes). Without the consent of at least 75% in
principal amount of the Notes then outstanding (including consents obtained in
connection with a tender offer or exchange offer for, or purchase of, such
Notes), no waiver or amendment to this Indenture may make any change in the
provisions of Article 10 hereof that adversely affects the rights of any Holder
of Notes. Section 2.08 hereof shall determine which Notes are considered to be
"outstanding" for purposes of this Section 9.02.

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

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

                                       76
<PAGE>   82

          After an amendment, supplement or waiver under this Section becomes
effective, the Company shall mail to the Holders of Notes affected thereby a
notice briefly describing the amendment, supplement or waiver. Any failure of
the Company to mail such notice, or any defect therein, shall not, however, in
any way impair or affect the validity of any such amended or supplemental
Indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a
majority in aggregate principal amount of the Notes (including Additional Notes,
if any) then outstanding voting as a single class may waive compliance in a
particular instance by the Company with any provision of this Indenture or the
Notes. However, without the consent of each Holder affected, an amendment or
waiver under this Section 9.02 may not (with respect to any Notes held by a
non-consenting Holder):

          (a) reduce the principal amount of Notes whose Holders must consent to
an amendment, supplement or waiver;

          (b) reduce the principal of or change the fixed maturity of any Note
or alter the provisions with respect to the redemption of the Notes (other than
provisions relating to Sections 3.09 or 4.15 hereof);

          (c) reduce the rate of or change the time for payment of interest on
any Note;

          (d) waive a Default or Event of Default in the payment of principal,
or interest or premium, or Liquidated Damages, if any, on the Notes (except a
rescission of acceleration of the Notes by the Holders of at least a majority in
aggregate principal amount of the Notes (including Additional Notes, if any) and
a waiver of the payment default that resulted from such acceleration);

          (e) make any Note payable in money other than that stated in the
Notes;

          (f) make any change in the provisions of this Indenture relating to
waivers of past Defaults or the rights of Holders of Notes to receive payments
of principal of, or interest or premium or Liquidated Damages, if any, on the
Notes;

          (g) waive a redemption payment with respect to any Note (other than a
payment required by Sections 3.09 or 4.15 hereof); or

          (h) release any Guarantor from any of its obligations under its
Guaranty or this Indenture, except in accordance with the terms of this
Indenture; or

          (i) make any change in Section 6.04 or 6.07 hereof or in the preceding
amendment and waiver provisions.

SECTION 9.03. Compliance with Trust Indenture Act.

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

SECTION 9.04. Revocation and Effect of Consents.

          Until an amendment, supplement or waiver becomes effective, a consent
to it by a Holder of a Note is a continuing consent by the Holder of a Note and
every subsequent Holder of a Note

                                       77
<PAGE>   83

or portion of a Note that evidences the same debt as the consenting Holder's
Note, even if notation of the consent is not made on any Note. However, any such
Holder of a Note or subsequent Holder of a Note may revoke the consent as to its
Note if the Trustee receives written notice of revocation before the date the
waiver, supplement or amendment becomes effective. An amendment, supplement or
waiver becomes effective in accordance with its terms and thereafter binds every
Holder.

SECTION 9.05. Notation on or Exchange of Notes.

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

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

SECTION 9.06. Trustee to Sign Amendments, etc.

          The Trustee shall sign any amended or supplemental Indenture
authorized pursuant to this Article 9 if the amendment or supplement does not
adversely affect the rights, duties, liabilities or immunities of the Trustee.
The Company may not sign an amendment or supplemental Indenture until the Board
of Directors approves it. In executing any amended or supplemental indenture,
the Trustee shall be entitled to receive and (subject to Section 7.01 hereof)
shall be fully protected in relying upon, in addition to the documents required
by Section 11.04 hereof, an Officer's Certificate and an Opinion of Counsel
stating that the execution of such amended or supplemental indenture is
authorized or permitted by this Indenture.

                                  ARTICLE 10.
                                  SUBORDINATION

SECTION 10.01. Agreement to Subordinate.

          The Company agrees, and each Holder by accepting a Note agrees, that
the Indebtedness evidenced by the Notes is subordinated in right of payment, to
the extent and in the manner provided in this Article 10, to the prior payment
in full of all Senior Debt of the Company, including Senior Debt incurred after
the date of this Indenture, and that the subordination is for the benefit of the
holders of Senior Debt.

SECTION 10.02. Liquidation; Dissolution; Bankruptcy.

          Upon any distribution to creditors of the Company in a liquidation or
dissolution of the Company, in a bankruptcy, reorganization, insolvency,
receivership or similar proceeding relating to the Company or its property, in
an assignment for the benefit of creditors or in any marshalling of the
Company's assets and liabilities:

          (i) holders of Senior Debt shall be entitled to receive payment in
     full of all Obligations due in respect of such Senior Debt (including
     interest after the commencement of any such proceeding at the rate
     specified in the applicable Senior Debt) before Holders of the

                                       78
<PAGE>   84

     Notes shall be entitled to receive any payment with respect to the Notes
     (except that Holders may receive (i) Permitted Junior Securities and (ii)
     payments and other distributions made from any defeasance trust created
     pursuant to Section 8.01 hereof); and

          (ii) until all Obligations with respect to Senior Debt (as provided in
     subsection (i) above) are paid in full, any distribution to which Holders
     would be entitled but for this Article 10 shall be made to the holders of
     Senior Debt (except that Holders of Notes may receive (i) Permitted Junior
     Securities and (ii) payments and other distributions made from any
     defeasance trust created pursuant to Section 8.01 hereof), as their
     interests may appear.

SECTION 10.03. Default on Designated Senior Debt.

     (a) The Company may not make any payment or distribution to the Trustee or
any Holder in respect of Obligations with respect to the Notes and may not
acquire from the Trustee or any Holder any Notes for cash or property (other
than (i) Permitted Junior Securities and (ii) payments and other distributions
made from any defeasance trust created pursuant to Section 8.01 hereof) until
all principal and other Obligations with respect to the Senior Debt have been
paid in full if:

          (i) a default in the payment of any principal or other Obligations
     with respect to Designated Senior Debt occurs and is continuing beyond any
     applicable grace period in the agreement, indenture or other document
     governing such Designated Senior Debt; or

          (ii) a default, other than a payment default, on Designated Senior
     Debt occurs and is continuing on any series of Designated Senior Debt that
     permits holders of that series to accelerate its maturity and the Trustee
     receives a notice of the default (a "Payment Blockage Notice") from the
     Company or the holders (or a Representative of the holders) of the
     Designated Senior Debt. If the Trustee receives any such Payment Blockage
     Notice, no subsequent Payment Blockage Notice shall be effective for
     purposes of this Section unless and until (i) at least 360 days shall have
     elapsed since the delivery of the immediately prior Payment Blockage Notice
     and (ii) all scheduled payments of principal, interest and premium and
     Liquidated Damages, if any, on the Notes that have come due have been paid
     in full in cash. No nonpayment default that existed or was continuing on
     the date of delivery of any Payment Blockage Notice to the Trustee shall
     be, or be made, the basis for a subsequent Payment Blockage Notice unless
     such default shall have been cured or waived for a period of 90 days.

     (b) The Company may and shall resume payments on and distributions in
respect of the Notes and may acquire them upon the earlier of:

               (i) in the case of a payment default, upon the date on which such
     default is cured or waived, or

               (ii) in the case of a nonpayment default, the earlier of the date
     on which such nonpayment default is cured or waived or 179 days after the
     date on which the applicable Payment Blockage Notice is received, unless
     the maturity of any Designated Senior Debt has been accelerated.

                                       79
<PAGE>   85

SECTION 10.04. Acceleration of Notes.

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

SECTION 10.05. When Distribution Must Be Paid Over.

          In the event that the Trustee or any Holder receives any payment of
any Obligations with respect to the Notes (except in Permitted Junior Securities
or payments and other distributions made from any defeasance trust created
pursuant to Section 8.01 hereof) at a time when the payment is prohibited by
this Article 10 and the Trustee or such Holder, as applicable, has actual
knowledge (provided by formal notice in accordance with Section 10.06 hereof in
the case of the Trustee) that such payment is prohibited by Section 10.03
hereof, such payment shall be held by the Trustee or such Holder, in trust for
the benefit of, and shall be paid forthwith over and delivered, upon written
request, to, the holders of Senior Debt as their interests may appear or their
Representative under the indenture or other agreement (if any) pursuant to which
Senior Debt may have been issued, as their respective interests may appear, for
application to the payment of all Obligations with respect to Senior Debt
remaining unpaid to the extent necessary to pay such Obligations in full in
accordance with their terms, after giving effect to any concurrent payment or
distribution to or for the holders of Senior Debt.

          With respect to the holders of Senior Debt, the Trustee undertakes to
perform only such obligations on the part of the Trustee as are specifically set
forth in this Article 10, and no implied covenants or obligations with respect
to the holders of Senior Debt shall be read into this Indenture against the
Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Senior Debt, and shall not be liable to any such holders if the
Trustee shall pay over or distribute to or on behalf of Holders or the Company
or any other Person money or assets to which any holders of Senior Debt shall be
entitled by virtue of this Article 10, except if such payment is made as a
result of the willful misconduct or gross negligence of the Trustee.

SECTION 10.06. Notice by Company.

          The Company shall promptly notify the Trustee and the Paying Agent of
any facts known to the Company that would cause a payment of any Obligations
with respect to the Notes to violate this Article 10, but failure to give such
notice shall not affect the subordination of the Notes to the Senior Debt as
provided in this Article 10.

SECTION 10.07. Subrogation.

          After all Senior Debt is paid in full and until the Notes are paid in
full, Holders of Notes shall be subrogated (equally and ratably with all other
Indebtedness pari passu with the Notes) to the rights of holders of Senior Debt
to receive distributions applicable to Senior Debt to the extent that
distributions otherwise payable to the Holders of Notes have been applied to the
payment of Senior Debt. A distribution made under this Article 10 to holders of
Senior Debt that otherwise would have been made to Holders of Notes is not, as
between the Company and Holders, a payment by the Company on the Notes.

                                       80
<PAGE>   86

SECTION 10.08. Relative Rights.

          This Article 10 defines the relative rights of Holders of Notes and
holders of Senior Debt. Nothing in this Indenture shall:

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

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

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

          If the Company fails because of this Article 10 to pay principal of or
interest on a Note on the due date, the failure is still a Default or Event of
Default.

SECTION 10.09. Subordination May Not Be Impaired by Company.

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

SECTION 10.10. Distribution or Notice to Representative.

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

          Upon any payment or distribution of assets of the Company referred to
in this Article 10, the Trustee and the Holders of Notes shall be entitled to
rely upon any order or decree made by any court of competent jurisdiction or
upon any certificate of such Representative or of the liquidating trustee or
agent or other Person making any distribution to the Trustee or to the Holders
of Notes for the purpose of ascertaining the Persons entitled to participate in
such distribution, the holders of the Senior Debt 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.

SECTION 10.11. Rights of Trustee and Paying Agent.

          Notwithstanding the provisions of this Article 10 or any other
provision of this Indenture, the Trustee shall not be charged with knowledge of
the existence of any facts that would prohibit the making of any payment or
distribution by the Trustee, and the Trustee and the Paying Agent may continue
to make payments on the Notes, unless the Trustee shall have received at its
Corporate Trust Office at least five Business Days prior to the date of such
payment written notice of facts that would cause the payment of any Obligations
with respect to the Notes to violate this Article 10. Only the Company or a
Representative may give the notice. Nothing in this Article 10 shall impair the
claims of, or payments to, the Trustee under or pursuant to Section 7.07 hereof.

                                       81
<PAGE>   87

          The Trustee in its individual or any other capacity may hold Senior
Debt of the Company with the same rights it would have if it were not Trustee.
Any Agent may do the same with like rights.

SECTION 10.12. Authorization to Effect Subordination.

          Each Holder of Notes, by the Holder's acceptance thereof, authorizes
and directs the Trustee on such Holder's behalf to take such action as may be
necessary or appropriate to effectuate the subordination as provided in this
Article 10, and appoints the Trustee to act as such Holder's attorney-in-fact
for any and all such purposes. If the Trustee does not file a proper proof of
claim or proof of debt in the form required in any proceeding referred to in
Section 6.09 hereof at least 30 days before the expiration of the time to file
such claim the holders of the Senior Debt of the Company or their
Representatives are hereby authorized to file an appropriate claim for and on
behalf of the Holders of the Notes.

SECTION 10.13. Amendments.

          The provisions of this Article 10 shall not be amended or modified
without the written consent of the holders of all Senior Debt.

                                  ARTICLE 11.
                                   GUARANTIES

SECTION 11.01. Guaranty.

          Subject to this Article 11, each of the Guarantors hereby, jointly and
severally, unconditionally guarantees to each Holder of a Note authenticated and
delivered by the Trustee and to the Trustee and its successors and assigns,
irrespective of the validity and enforceability of this Indenture, the Notes or
the obligations of the Company hereunder or thereunder, that: (a) the principal
of and interest on the Notes will be promptly paid in full when due, whether at
maturity, by acceleration, redemption or otherwise, and interest on the overdue
principal of and interest on the Notes, if any, if lawful, and all other
obligations of the Company to the Holders or the Trustee hereunder or thereunder
will be promptly paid in full or performed, all in accordance with the terms
hereof and thereof; and (b) in case of any extension of time of payment or
renewal of any Notes or any of such other obligations, that same will be
promptly paid in full when due or performed in accordance with the terms of the
extension or renewal, whether at stated maturity, by acceleration or otherwise.
Failing payment when due of any amount so guaranteed or any performance so
guaranteed for whatever reason, the Guarantors shall be jointly and severally
obligated to pay the same immediately. Each Guarantor agrees that this is a
guarantee of payment and not a guarantee of collection.

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

                                       82
<PAGE>   88

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

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

          Each Guarantor agrees that it shall not be entitled to any right of
subrogation in relation to the Holders in respect of any obligations guaranteed
hereby until payment in full of all obligations guaranteed hereby. Each
Guarantor further agrees that, as between the Guarantors, on the one hand, and
the Holders and the Trustee, on the other hand, (x) the maturity of the
obligations guaranteed hereby may be accelerated as provided in Article 6 hereof
for the purposes of this Guaranty, notwithstanding any stay, injunction or other
prohibition preventing such acceleration in respect of the obligations
guaranteed hereby, and (y) in the event of any declaration of acceleration of
such obligations as provided in Article 6 hereof, such obligations (whether or
not due and payable) shall forthwith become due and payable by the Guarantors
for the purpose of this Guaranty. The Guarantors shall have the right to seek
contribution from any non-paying Guarantor so long as the exercise of such right
does not impair the rights of the Holders under the Guaranty.

SECTION 11.02. Subordination of Guaranty.

          The Obligations of each Guarantor under its Guaranty pursuant to this
Article 11 shall be junior and subordinated to the Senior Debt of such Guarantor
on the same basis as the Notes are junior and subordinated to Senior Debt of the
Company. For the purposes of the foregoing sentence, the Trustee and the Holders
shall have the right to receive and/or retain payments by any of the Guarantors
only at such times as they may receive and/or retain payments in respect of the
Notes pursuant to this Indenture, including Article 10 hereof.

SECTION 11.03. Limitation on Guarantor Liability.

          Each Guarantor other than DASI, and by its acceptance of Notes, each
Holder, hereby confirms that it is the intention of all such parties that the
Guaranty of such Guarantor other than DASI not constitute a fraudulent transfer
or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance
Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to
the extent applicable to any Guaranty. To effectuate the foregoing intention,
the Trustee, the Holders and the Guarantors other than DASI hereby irrevocably
agree that the obligations of such Guarantor under its Guaranty and this Article
11 shall be limited to the maximum amount as will, after giving effect to such
maximum amount and all other contingent and fixed liabilities of such Guarantor
that are relevant under such laws, and after giving effect to any collections
from, rights to receive contribution from or payments made by or on behalf of
any other Guarantor in respect of the obligations of such other Guarantor under
this Article 11, result in the obligations of such Guarantor under its Guaranty
not constituting a fraudulent transfer or conveyance.

SECTION 11.04. Execution and Delivery of Guaranty.

                  To evidence its Guaranty set forth in Section 11.01, each
Guarantor hereby agrees that a

                                       83
<PAGE>   89

notation of such Guaranty substantially in the form included in Exhibit E shall
be endorsed by an Officer of such Guarantor on each Note authenticated and
delivered by the Trustee and that this Indenture shall be executed on behalf of
such Guarantor by its President or one of its Vice Presidents.

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

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

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

          In the event that the Company creates or acquires any new Subsidiaries
subsequent to the date of this Indenture, if required by Section 4.17 hereof,
the Company shall cause such Subsidiaries to execute supplemental indentures to
this Indenture in the form of Exhibit F hereto and Guaranties in accordance with
Section 4.17 hereof and this Article 11, to the extent applicable.

SECTION 11.05. Guarantors May Consolidate, etc., on Certain Terms.

          Except as otherwise provided in Section 11.06, a Guarantor may not
sell or otherwise dispose of all or substantially all of its assets to, or
consolidate with or merge with or into (whether or not such Guarantor is the
surviving Person) another Person, other than the Company or another Guarantor
unless:

     (a) immediately after giving effect to that transaction, no Default or
Event of Default exists; and

     (b) either:

          (i) the Person acquiring the property in any such sale or disposition
     or the Person formed by or surviving any such consolidation or merger
     assumes all the obligations of that Guarantor under this Indenture, its
     Guaranty and the Registration Rights Agreement, pursuant to a supplemental
     indenture and appropriate collateral documents in form and substance
     reasonably satisfactory to the Trustee; or

          (ii) the Net Proceeds of such sale or other disposition are applied in
     accordance with the applicable provisions of this Indenture.

          In case of any such consolidation, merger, sale or conveyance and upon
the assumption by the successor Person, by supplemental indenture, executed and
delivered to the Trustee and satisfactory in form to the Trustee, of the
Guaranty endorsed upon the Notes and the due and punctual performance of all of
the covenants and conditions of this Indenture to be performed by the Guarantor,
such successor Person shall succeed to and be substituted for the Guarantor with
the same effect as if it had been named herein as a Guarantor. Such successor
Person thereupon may cause to be signed any or all of the Guaranties to be
endorsed upon all of the Notes issuable hereunder which theretofore shall not
have been signed by the Company and delivered to the Trustee. All the Guaranties
so issued shall in all

                                       84
<PAGE>   90

respects have the same legal rank and benefit under this Indenture as the
Guaranties theretofore and thereafter issued in accordance with the terms of
this Indenture as though all of such Guaranties had been issued at the date of
the execution hereof.

          Except as set forth in Articles 4 and 5 hereof, and notwithstanding
clauses (a) and (b) above, nothing contained in this Indenture or in any of the
Notes shall prevent any consolidation or merger of a Guarantor with or into the
Company or another Guarantor, or shall prevent any sale or conveyance of the
property of a Guarantor as an entirety or substantially as an entirety to the
Company or another Guarantor.

SECTION 11.06. Releases Following Sale of Assets.

          The Guaranty of a Guarantor will be released:

     (a) in connection with any sale or other disposition of all or
substantially all of the assets of that Guarantor (including by way of merger or
consolidation) to a Person that is not (either before or after giving effect to
such transaction) a Restricted Subsidiary of the Company, if the Guarantor
applies the Net Proceeds of that sale or other disposition in accordance with
the applicable provisions of this Indenture, including without limitation
Section 4.10 hereof; or

     (b) in connection with any sale of all of the capital stock of a Guarantor
to a Person that is not (either before or after giving effect to such
transaction) a Restricted Subsidiary of the Company, if the Company applies the
Net Proceeds of that sale in accordance with the applicable provisions of this
Indenture, including without limitation Section 4.10 hereof; or

     (c) if the Company properly designates any Restricted Subsidiary that is a
Guarantor as an Unrestricted Subsidiary.

          Upon delivery by the Company to the Trustee of an Officers'
Certificate and an Opinion of Counsel to the effect that such sale or other
disposition was made by the Company in accordance with the applicable provisions
of this Indenture, including without limitation Section 4.10 hereof, the Trustee
shall execute any documents reasonably required in order to evidence the release
of any Guarantor from its obligations under its Guaranty.

          Any Guarantor not released from its obligations under its Guaranty
shall remain liable for the full amount of principal of and interest on the
Notes and for the other obligations of any Guarantor under this Indenture as
provided in this Article 11.

                                  ARTICLE 12.

SECTION 12.01. Trust Indenture Act Controls.

          If any provision of this Indenture limits, qualifies or conflicts with
the duties imposed by TIA ss. 318(c), the imposed duties shall control.

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

         1. INTEREST. Dura Operating Corp., a Delaware corporation (the
"Company"), promises to pay interest on the principal amount of this Note at 9%
per annum from May 1, 2001 until maturity and shall pay the Liquidated Damages
payable pursuant to Section 5 of the Registration Rights Agreement referred to
below. The Company shall pay interest and Liquidated Damages semi-annually on
May 1 and November 1 of each year, or if any such day is not a Business Day, on
the next succeeding Business Day (each an "Interest Payment Date"). Interest on
the Notes will accrue from the most recent date to which interest has been paid
or, if no interest has been paid, from the date of issuance; provided that if
there is no existing Default in the payment of interest, and if this Note is
authenticated between a record date referred to on the face hereof and the next
succeeding Interest Payment Date, interest shall accrue from such next
succeeding Interest Payment Date; provided, further, that the first Interest
Payment Date shall be November 1, 2001. The Company shall pay interest
(including post-petition interest in any proceeding under any Bankruptcy Law) on
overdue principal and premium, if any, from time to time on demand at a rate
that is 1% per annum in excess of the rate then in effect; it shall pay interest
(including post-petition interest in any proceeding under any Bankruptcy Law) on
overdue installments of interest and Liquidated Damages (without regard to any
applicable grace periods) from time to time on demand at the same rate to the
extent lawful. Interest 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 Notes
(except defaulted interest) and Liquidated Damages to the Persons who are
registered Holders of Notes at the close of business on the April 15 or October
15 next preceding the Interest Payment Date, even if such Notes are canceled
after such record date and on or before such Interest Payment Date, except as
provided in Section 2.12 of the Indenture with respect to defaulted interest.
The Notes will be payable as to principal, premium and Liquidated Damages, if
any, and interest at the office of the paying agent in New York City, or, at the
option of the Company, payment of interest and Liquidated Damages may be made by
check mailed to the Holders at their addresses set forth in the register of
Holders, and provided that payment by wire transfer of immediately available
funds will be required with respect to principal of and interest, premium and
Liquidated Damages on, all Global Notes and all other Notes the Holders of which
shall have provided wire transfer instructions to the Company or the Paying
Agent. Such payment shall be in such coin or currency of the United States of
America as at the time of payment is legal tender for payment of public and
private debts.

         3. PAYING AGENT AND  REGISTRAR.  Initially,  U.S.  Bank Trust  National
Association,  the Trustee  under the Indenture,  will act as  principal  Paying
Agent and  Registrar.  The  Company  may  change  any  Paying  Agent or
Registrar  without notice to any Holder.  If and as long as the Notes are listed
on the Luxembourg  Stock Exchange, the Company  will  maintain a paying agent in
Luxembourg.  The Company or any of its  Subsidiaries  may act in any such
capacity.

         4. INDENTURE. The Company issued the Notes under an Indenture, dated as
of June 22, 2001 (the "Indenture"), among the Company, the Guarantors and the
Trustee. The terms of the Notes include those stated in the Indenture and those
made part of the Indenture by reference to the Trust Indenture Act of 1939, as
amended (15 U.S. Code ss.ss. 77aaa-77bbbb). The Notes are subject to all such
terms, and Holders are referred to the Indenture and such Act for a statement of
such terms. To the extent any provision of this Note conflicts with the express
provisions of the Indenture, the provisions of the Indenture shall govern and be
controlling. The Notes are obligations of the Company initially limited

                                      A-3
<PAGE>   98
to $600.0 million in aggregate principal amount. The Indenture pursuant to which
this Note is issued provides that up to $141.5 million Additional Notes may be
issued thereunder.

         5. OPTIONAL REDEMPTION.

         (a) Except as set forth in subparagraph (b) of this Paragraph 5, the
Notes will not be redeemable at the Company's option prior to May 1, 2004.
Thereafter, the Notes will be subject to redemption any time at the option of
the Company, in whole or in part, upon not less than 30 nor more than 60 days'
notice, at the redemption prices (expressed as percentages of principal amount)
set forth below plus accrued and unpaid interest and Liquidated Damages, if any,
thereon to the applicable redemption date, if redeemed during the twelve-month
period beginning on May 1 of the years indicated below:

            YEAR                                     PERCENTAGE
            ----                                     ----------
            2004....................................   104.5 %
            2005....................................   103.0 %
            2006....................................   101.5 %
            2007 and thereafter.....................   100.0 %

         (b) Notwithstanding the provisions of subparagraph (a) of this
Paragraph 5, before May 1, 2002, the Company may on any one or more occasions
redeem up to 35% of the aggregate principal amount of Notes issued under the
Indenture (calculated after giving effect to any issuance of Additional Notes)
at a redemption price of 109% of the principal amount thereof, plus accrued and
unpaid interest and Liquidated Damages thereon, if any, to the redemption date,
with the net cash proceeds of any Equity Offerings; provided that at least 65%
of the aggregate principal amount of Notes issued under the Indenture remains
outstanding immediately after the occurrence of such redemption (excluding Notes
held by Dura Automotive Systems, Inc., the Company and their respective
Subsidiaries); and provided further that such redemption shall occur within 90
days of the date of the closing of any such Equity Offering.

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

         7. REPURCHASE AT OPTION OF HOLDER.

         (a) If there is a Change of Control, the Company shall be required to
make an offer (a "Change of Control Offer") to repurchase all or any part (equal
to $1,000 or an integral multiple thereof) of each Holder's Notes at a purchase
price equal to 101% of the aggregate principal amount thereof plus accrued and
unpaid interest and Liquidated Damages thereon, if any, to the date of purchase
(the "Change of Control Payment"). Within 30 days following any Change of
Control, the Company shall mail a notice to each Holder setting forth the
procedures governing the Change of Control Offer as required by the Indenture.

         (b) When the aggregate amount of Excess Proceeds exceeds $20.0 million,
the Company will make an Asset Sale Offer to all Holders of Notes and all
holders of other Indebtedness that is pari passu with the Notes containing
provisions similar to those set forth in the Indenture with

                                      A-4
<PAGE>   99
respect to offers to purchase or redeem with the proceeds of sales of assets to
purchase the maximum principal amount of Notes and such other pari passu
Indebtedness that may be purchased out of the Excess Proceeds. The offer price
in any Asset Sale Offer will be equal to 100% of the principal amount plus
accrued and unpaid interest and Liquidated Damages, if any, to the date of
purchase, and will be payable in cash. If any Excess Proceeds remain after
consummation of an Asset Sale Offer, the Company may use such Excess Proceeds
for any purpose not otherwise prohibited by the Indenture. If the aggregate
principal amount of Notes and such other pari passu Indebtedness tendered into
such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee shall

whose Notes are to be redeemed at its registered address. Notes in denominations
larger than $1,000 may be redeemed in part but only in whole multiples of

called for redemption.

         9. DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered form
without coupons in denominations of $1,000 and integral multiples of $1,000. The

things, to furnish appropriate endorsements and transfer documents and the
Company may require a Holder to pay any taxes and fees required by law or
permitted by the Indenture. The Company need not exchange or register the
transfer of any Note or portion of a Note selected for redemption, except for
the unredeemed portion of any Note being redeemed in part. Also, the Company
need not exchange or register the transfer of any Notes for a period of 15 days
before a selection of Notes to be redeemed or during the period between a record
date and the corresponding Interest Payment Date.

         10. PERSONS DEEMED OWNERS.  The registered Holder of a Note will be

         11. AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain exceptions,
the Indenture, the Guaranties or the Notes may be amended or supplemented with
the consent of the Holders of at least a majority in principal amount of the
then outstanding Notes and Additional Notes, if any, voting as a single class,
and any existing default or compliance with any provision of the Indenture, the
Guaranties or the Notes may be waived with the consent of the Holders of a
majority in principal amount of the then outstanding Notes and Additional Notes,
if any, voting as a single class. Without the consent of any Holder of a Note,
the Indenture, the Guaranties or the Notes may be amended or supplemented to
cure any ambiguity, defect or inconsistency, to provide for uncertificated Notes
in addition to or in place of certificated Notes, to provide for the assumption
of the Company's or Guarantor's obligations to Holders of the Notes in case of a
merger or consolidation or sale of all or substantially all of the Company's
assets, to make any change that would provide any additional rights or benefits
to the Holders of the Notes or that does not adversely affect the legal rights
under the Indenture of any such Holder, to comply with the requirements of the
Commission in order to effect or maintain the qualification of the Indenture
under the Trust Indenture Act, to provide for the issuance of Additional

                                      A-5
<PAGE>   100
Notes in accordance with the limitations set forth in the Indenture, or to allow
any Guarantor to execute a supplemental indenture to the Indenture and/or
Guaranties with respect to the Notes.

         12. DEFAULTS AND REMEDIES. Events of Default include: (i) default for
30 days in the payment when due of interest, on, or Liquidated Damages with
respect to, the Notes whether or not prohibited by Article 10 of the Indenture;
(ii) the default in payment when due of the principal of, or premium, if any, on
the Notes, whether or not prohibited by Article 10 of the Indenture; (iii)
failure by the Company or any of its Restricted Subsidiaries to comply with the
provisions of Section 5.01 of the Indenture; (iv) failure by the Company or any
of its Restricted Subsidiaries for 60 days after specified notice from the
Trustee or the Holders of at least 25% of the outstanding principal amount of
the Notes to comply with any of the other agreements in the Indenture or the
Notes; (v) default under any mortgage, indenture or instrument under which there
is issued and outstanding any Indebtedness for money borrowed by the Company or
any of its Restricted Subsidiaries (or the payment of which is guaranteed by the
Company or any of its Restricted Subsidiaries) whether such Indebtedness or
guarantee now exists, or is created after the date of the Indenture, if that
default: (A) is caused by a failure to pay principal of, or interest or premium,
if any, on such Indebtedness prior to the expiration of the grace period
provided in such Indebtedness on the date of such default (a "Payment Default");
or (B) results in the acceleration of such Indebtedness prior to its express
maturity, and, in each case, the principal amount of any such Indebtedness,
together with the principal amount of any other such Indebtedness the maturity
of which has been so accelerated, aggregates $20.0 million or more; (vi) failure
by the Company or any of its Restricted Subsidiaries to pay final judgments
aggregating in excess of $20.0 million, which judgments are not paid, vacated,
discharged or stayed or non-appealable for a period of 60 days, and in the event
such judgment is covered by insurance, an enforcement proceeding has been
commenced by any creditor upon such judgment or decree which is not promptly
stayed; (vii) except as permitted by the Indenture, any Guaranty shall be held
in any judicial proceeding to be unenforceable or invalid or shall cease for any
reason to be in full force and effect or any Guarantor, or any Person acting on
behalf of any Guarantor, shall deny or disaffirm its obligations under its
Subsidiary Guaranty or DASI, or any Person acting on behalf of DASI, shall deny
or disaffirm its obligations under the Parent Guaranty; and (viii) certain
events of bankruptcy or insolvency with respect to DASI, the Company or any of
its Significant Subsidiaries. If any Event of Default occurs and is continuing,
the Trustee or the Holders of at least 25% in principal amount of the then
outstanding Notes may declare all the Notes to be due and payable.
Notwithstanding the foregoing, in the case of an Event of Default arising from
certain events of bankruptcy or insolvency, all outstanding Notes will become
due and payable without further action or notice. Holders may not enforce the
Indenture or the Notes except as provided in the Indenture. Subject to certain
limitations, Holders of a majority in principal amount of the then outstanding
Notes may direct the Trustee in its exercise of any trust or power. The Trustee
may withhold from Holders of the Notes notice of any continuing Default or Event
of Default (except a Default or Event of Default relating to the payment of
principal or interest or Liquidated Damages) if it determines that withholding
notice is in their interest. The Holders of a majority in aggregate principal
amount of the Notes then outstanding by notice to the Trustee may on behalf of
the Holders of all of the Notes waive any existing Default or Event of Default
and its consequences under the Indenture except a continuing Default or Event of
Default in the payment of interest or Liquidated Damages on, or the principal
of, the Notes. The Company is required to deliver to the Trustee annually a
statement regarding compliance with the Indenture, and the Company is required
upon becoming aware of any Default or Event of Default, to deliver to the
Trustee a statement specifying such Default or Event of Default.

Indebtedness evidenced by the Note is subordinated in right of payment, to the
extent and in the manner provided in Article 10 of the Indenture, to the prior
payment in full of all Senior Debt of the Company, including Senior Debt
incurred after the date of the Indenture, and that the subordination is for the
benefit of the holders of Senior Debt.

         14. GUARANTIES. The payment of principal of, premium, and interest and
Liquidated Damages, if any, on the Notes are unconditionally guaranteed, jointly
and severally, on a senior subordinated basis by the Guarantors.

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

         16. NO RECOURSE AGAINST OTHERS. A director, officer, employee,
incorporator or stockholder, of the Company or any Guarantor, as such, shall not
have any liability for any obligations of the Company or the Guarantors under
the Notes, the Indenture, the Subsidiary Guaranties, the Parent Guaranty or for
any claim based on, in respect of, or by reason of, such obligations or their
creation. Each Holder by accepting a Note waives and releases all such
liability. The waiver and release are part of the consideration for the issuance
of the Notes.

                  a proceeding first against the Company, protest, notice and
                  all demands whatsoever.

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

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

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

         (g)      As between the Guarantors, on the one hand, and the Holders
                  and the Trustee, on the other hand, (x) the maturity of the
                  obligations guaranteed hereby may be accelerated as provided
                  in Article 6 of the Indenture for the purposes of this
                  Subsidiary Guarantee, notwithstanding any stay, injunction or
                  other prohibition preventing such acceleration in respect of
                  the obligations guaranteed hereby, and (y) in the event of any
                  declaration of acceleration of such obligations as provided in
                  Article 6 of the Indenture,  such obligations (whether or not
                  due and payable) shall forthwith become due and payable by the
                  Guarantors for the purpose of this Subsidiary Guarantee.

         (h)      The Guarantors shall have the right to seek contribution from
                  any non-paying Guarantor so long as the exercise of such right
                  does not impair the rights of the Holders under the Guarantee.

         (i)      Pursuant to Section 11.03 of the Indenture, after giving
                  effect to any maximum amount and any other contingent and
                  fixed liabilities that are relevant under any applicable
                  Bankruptcy or fraudulent conveyance laws, and after giving
                  effect to any collections from, rights to receive contribution
                  from or payments made by or on behalf of any other Guarantor
                  in respect of the obligations of such other Guarantor under
                  Article 11 of the Indenture shall result in the obligations of
                  such Guarantor under its Subsidiary Guarantee not constituting
                  a fraudulent transfer or conveyance.

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

         4.       GUARANTEEING SUBSIDIARY MAY CONSOLIDATE, ETC. ON CERTAIN
TERMS.

     (a) A Guaranteeing Subsidiary may not sell or otherwise dispose of all
         or substantially all of its assets to, or consolidate with or merge
         with or into (whether or not such Guaranteeing Subsidiary is the
         surviving Person) another Person unless:

         (i)      immediately  after  giving  effect to such  transaction,  no
                  Default or Event of Default exists; and

         (ii)     either:

                  (A)      the Person acquiring the property in any such sale or
                           disposition or the Person formed by or surviving any
                           such consolidation or merger assumes all the
                           obligations of such Guaranteeing Subsidiary under the
                           Indenture, the Guaranty and the Registration Rights
                           Agreement, pursuant to a supplemental indenture
                           satisfactory to the Trustee and appropriate
                           collateral documents satisfactory to the Trustee; or

                  (B)      the Net Proceeds of such sale or other disposition
                           are applied in accordance with the applicable
                           provisions of the Indenture.

         (b)      In case of any such consolidation, merger, sale or conveyance
                  and upon the assumption by the successor Person, by
                  supplemental indenture, executed and delivered to the Trustee
                  and satisfactory in form to the Trustee, of the Subsidiary
                  Guarantee endorsed upon the Notes and the due and punctual
                  performance of all of the covenants and conditions of the
                  Indenture to be performed by the Guarantor, such successor
                  corporation shall succeed to and be substituted for the
                  Guarantor with the same effect as if it had been named herein
                  as a Guarantor. Such successor corporation thereupon may cause
                  to be signed any or all of the Subsidiary Guarantees to be
                  endorsed upon all of the Notes issuable hereunder which
                  theretofore shall not have been signed by the Company and
                  delivered to the Trustee. All the Subsidiary Guarantees so
                  issued shall in all respects

                                      F-3
<PAGE>   119
                  have the same legal rank and benefit under the Indenture as
                  the Subsidiary Guarantees theretofore and thereafter issued in
                  accordance with the terms of the Indenture as though all of
                  such Subsidiary Guarantees had been issued at the date of the
                  execution hereof.

         (c)      Except as set forth in Articles 4 and 5 of the Indenture, and
                  notwithstanding clauses (a) and (b) above, nothing contained
                  in the Indenture or in any of the Notes shall prevent any
                  consolidation or merger of a Guarantor with or into the
                  Company or another Guarantor, or shall prevent any sale or
                  conveyance of the property of a Guarantor as an entirety or
                  substantially as an entirety to the Company or another
                  Guarantor.

                  5.       RELEASES.

         (a)      The Subsidiary Guarantee of a Guarantor will be released (i)
                  in connection with any sale or other disposition of all or
                  substantially all of the assets of that Guarantor (including
                  by way of merger or consolidation), to a Person that is not
                  (either before or after giving effect to such transaction) a
                  Restricted Subsidiary of the Company, if the Guarantor applies
                  the Net Proceeds of that sale or other disposition in
                  accordance with Section 4.10 of the Indenture; (ii) in
                  connection with any sale of all of the capital stock of a
                  Guarantor to a person that is not (either before or after
                  giving effect to such transaction) a Restricted  Subsidiary of
                  the Company, if the Company applies the Net Proceeds of that
                  sale in accordance with Section 4.10 of the Indenture; or
                  (iii) if the Company properly designates any Restricted
                  Subsidiary that is a Guarantor as an Unrestricted Subsidiary.
                  Upon delivery by the Company to the Trustee of an Officers'
                  Certificate  and an Opinion of Counsel to the effect that such
                  sale or other disposition was made by the Company in
                  accordance with  the  provisions  of the  Indenture, including
                  without limitation Section 4.10 of the Indenture, the Trustee
                  shall execute any documents reasonably required in order to
                  evidence the release of any Guarantor from its obligations
                  under its Subsidiary Guarantee.

         (b)      Any Guarantor not released from its obligations under its
                  Subsidiary Guarantee shall remain liable for the full amount
                  of principal of and interest on the Notes and for the other
                  obligations of any Guarantor under the Indenture as provided
                  in Article 11 of the Indenture.

                  6. NO RECOURSE AGAINST OTHERS. No past, present or future
director, officer, employee, incorporator, stockholder or agent of the
Guaranteeing Subsidiary, as such, shall have any liability for any obligations
of the Company or any Guaranteeing Subsidiary under the Notes, any Subsidiary
Guarantees, the Indenture or this Supplemental Indenture or for any claim based
on, in respect of, or by reason of, such obligations or their creation. Each
Holder of the Notes by accepting a Note waives and releases all such liability.
The waiver and release are part of the consideration for issuance of the Notes.
Such waiver may not be effective to waive liabilities under the federal
securities laws and it is the view of the Commission that such a waiver is
against public policy.

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

                  9.       EFFECT OF HEADINGS.  The Section headings herein
are for convenience only and shall not affect the construction hereof.

                  10. THE TRUSTEE. The Trustee shall not be responsible in any
manner whatsoever for or in respect of the validity or sufficiency of this
Supplemental Indenture or for or in respect of the recitals contained herein,
all of which recitals are made solely by the Guaranteeing Subsidiary and the
Company.
