Ms. Dickerson:

In consideration of the sale to the holder by Wiltex A, Inc., (the "Company") of

and agrees for the benefit of the Company not to sell, offer to sell, solicit an

An attempt to sell, transfer or any type of disposition of the shares shall be a

         Any designation of a Subsidiary of the Company as an Unrestricted
Subsidiary shall be evidenced to the Trustee by filing with the Trustee a
certified copy of the Board Resolution giving effect to such designation and an

Subsidiary would fail to meet the preceding requirements as an Unrestricted
Subsidiary, it shall thereafter cease to be an Unrestricted Subsidiary for
purposes of this Indenture and any Indebtedness of such Subsidiary shall be
deemed to be incurred by a Restricted Subsidiary of the Company as of such date
and, if such Indebtedness is not permitted to be incurred as of such date under
Section 4.09 hereof, the Company shall be in default of such covenant. The Board
of Directors of the Company may at any time designate any Unrestricted
Subsidiary to be a Restricted Subsidiary; provided that such designation shall
be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of the
Company of any outstanding Indebtedness of such Unrestricted Subsidiary and such
designation shall only be permitted if (1) such Indebtedness is permitted under
Section 4.09 hereof, calculated on a pro forma basis as if such designation had
occurred at the beginning of the four-quarter reference period; and (2) no
Default or Event of Default would be in existence following such designation.

SECTION 2.01. FORM AND DATING.

         (a) General.

             The Notes and the Trustee's certificate of authentication shall be
substantially in the form of Exhibit A hereto. The Notes may have notations,
legends or endorsements required by law, stock exchange rule or usage. Each Note
shall be dated the date of its authentication. The Notes shall be in
denominations of $1,000 and integral multiples thereof.

             The terms and provisions contained in the Notes shall constitute,
and are hereby expressly made, a part of this Indenture and the Company, the
Guarantors and the Trustee, by their execution and delivery of this Indenture,
expressly agree to such terms and provisions and to be bound thereby. However,
to the extent any provision of any Note conflicts with the express provisions of
this Indenture, the provisions of this Indenture shall govern and be
controlling.

         (b) Global Notes.

             Notes issued in global form shall be substantially in the form of
Exhibit A attached hereto (including the Global Note Legend thereon and the
"Schedule of Exchanges of Interests in the Global Note" attached thereto). Notes
issued in definitive form shall be substantially in the form of Exhibit A
attached hereto (but without the Global Note Legend thereon and without the
"Schedule of Exchanges of Interests in the Global Note" attached thereto). Each
Global Note shall represent such of the outstanding Notes as shall be specified
therein and each shall provide that it shall represent the aggregate principal
amount of outstanding Notes from time to time endorsed thereon and that the
aggregate principal amount of outstanding Notes represented thereby may from
time to time be reduced or increased, as appropriate, to reflect exchanges and
redemptions. Any endorsement of a Global Note to reflect the amount of any
increase or decrease in the aggregate principal amount of outstanding Notes
represented thereby shall be made by the Trustee or the Custodian, at the
direction of the Trustee, in accordance with instructions given by the Holder
thereof as required by Section 2.06 hereof.

SECTION 2.02. EXECUTION AND AUTHENTICATION. Two Officers shall sign the Notes
for the Company by manual or facsimile signature. The Company's seal may be

             If an Officer whose signature is on a Note no longer holds that
office at the time a Note is authenticated, the Note shall nevertheless be
valid.

             A Note shall not be valid until authenticated by the manual
signature of the Trustee. The signature shall be conclusive evidence that the
Note has been authenticated under this Indenture.

             The Trustee shall, upon a written order of the Company signed by
two Officers (an "Authentication Order"), authenticate Notes for original issue
in unlimited aggregate principal amount, of which $350.0 million will be issued
as Initial Notes on the date hereof. The aggregate principal amount of Notes
outstanding at any time may not exceed such amount except as provided in Section
2.07 hereof.

                                       22

             The Trustee may appoint an authenticating agent acceptable to the
Company to authenticate Notes. An authenticating agent may authenticate Notes
whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by such agent. An

Affiliate of the Company.

SECTION 2.03. REGISTRAR AND PAYING AGENT.

             The Company shall maintain an office or agency where Notes may be
presented for registration of transfer or for exchange ("Registrar") and an

Registrar shall keep a register of the Notes and of their transfer and exchange.
The Company may appoint one or more co-registrars and one or more additional
paying agents. The term "Registrar" includes any co-registrar and the term
"Paying Agent" includes any additional paying agent. The Company may change any
Paying Agent or Registrar without notice to any Holder. The Company shall notify
the Trustee in writing of the name and address of any Agent not a party to this

its Subsidiaries may act as Paying Agent or Registrar.

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

             The Company initially appoints the Trustee to act as the principal
Registrar and Paying Agent and to act as Custodian with respect to the Global
Notes.

SECTION 2.04. PAYING AGENT TO HOLD MONEY IN TRUST.

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

SECTION 2.05. HOLDER LISTS.

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

SECTION 2.06.     TRANSFER AND EXCHANGE.

     (a)  Transfer and Exchange of Global Notes.

          A Global Note may not be transferred as a whole except by the
Depositary to a nominee of the Depositary, by a nominee of the Depositary to the
Depositary or to another nominee of the Depositary, the Depositary or any such
nominee to a successor Depositary or a nominee of such successor Depositary. All
Global Notes will be exchanged by the Company for Definitive Notes if (i) the
Company delivers to the Trustee notice from the Depositary that it is unwilling
or unable to continue to act as Depositary or that it is no longer a clearing
agency registered under the Exchange Act and, in either case, a successor
Depositary is not appointed by the Company within 90 days after the date of such
notice from the Depositary or (ii) there shall have occurred and be continuing a
Default or an Event of Default. Global Notes also may be exchanged or replaced,
in whole or in part, as provided in Sections 2.07 and 2.10 hereof. Upon the
occurrence of either of the preceding events in (i) or (ii) above, Definitive
Notes shall be issued in such names as the Depositary shall instruct the
Trustee. Every Note authenticated and delivered in exchange for, or in lieu of,
a Global Note or any portion thereof, pursuant to this Section 2.06 or Section
2.07 or 2.10 hereof, shall be authenticated and delivered in the form of, and
shall be, a Global Note. A Global Note may not be exchanged for another Note
other than as provided in this Section 2.06(a), however, beneficial interests in
a Global Note may be transferred and exchanged as provided in Section
2.06(b), (c) or (f) hereof.

     (b)  Transfer and Exchange of Beneficial Interests in the Global Notes.

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

          (i) Transfer of Beneficial Interests in the Same Global Note.
     Beneficial interests in any Restricted Global Note may be transferred to
     Persons who take delivery thereof in the form of a beneficial interest in
     the same Restricted Global Note in accordance with the transfer
     restrictions set forth in the Private Placement Legend. Beneficial
     interests in any Unrestricted Global Note may be transferred to Persons who
     take delivery thereof in the form of a beneficial interest in an
     Unrestricted Global Note. No written orders or instructions shall be
     required to be delivered to the Registrar to effect the transfers described
     in this Section 2.06(b)(i).

          (ii) All Other Transfers and Exchanges of Beneficial Interests in
     Global Notes. In connection with all transfers and exchanges of beneficial
     interests that are not subject to Section 2.06(b)(i) above, the transferor
     of such beneficial interest must deliver to the Registrar either (A) (1) a
     written order from a Participant or an Indirect Participant given to the
     Depositary in accordance with the Applicable Procedures directing the
     Depositary to credit or cause to be credited a beneficial interest in the
     Global Note in an amount equal to the beneficial interest to be transferred
     or exchanged and (2) instructions given in accordance with the Applicable
     Procedures containing information regarding the Participant account to be
     credited with such increase or (B) (1) a written order from a Participant
     or an Indirect Participant given to the Depositary in accordance with the
     Applicable Procedures directing the Depositary to cause to be issued a
     Definitive Note in an amount equal to the beneficial interest to be
     transferred or exchanged and (2) instructions given by the Depositary to
     the Registrar containing information

     regarding the Person in whose name such Definitive Note shall be registered
     to effect the transfer or exchange referred to in (1) above. Upon
     consummation of an Exchange Offer by the Company in accordance with Section
     2.06(f) hereof, the requirements of this Section 2.06(b)(ii) shall be
     deemed to have been satisfied upon receipt by the Registrar of the
     instructions contained in the Letter of Transmittal delivered by the Holder
     of such beneficial interests in the Restricted Global Notes. Upon
     satisfaction of all of the requirements for transfer or exchange of
     beneficial interests in Global Notes contained in this Indenture and the
     Notes or otherwise applicable under the Securities Act, the Trustee shall
     adjust the principal amount of the relevant Global Note(s) pursuant to
     Section 2.06(h) hereof.

          (iii) Transfer of Beneficial Interests to Another Restricted Global
     Note. A beneficial interest in any Restricted Global Note may be
     transferred to a Person who takes delivery thereof in the form of a
     beneficial interest in another Restricted Global Note if the transfer
     complies with the requirements of Section 2.06(b)(ii) above and the
     Registrar receives the following:

                (A) if the transferee will take delivery in the form of a

     deliver a certificate in the form of Exhibit B hereto, including the
     certifications in item (1) thereof; and

                (B) if the transferee will take delivery in the form of a
     beneficial interest in the Regulation S Global Note, then the transferor
     must deliver a certificate in the form of Exhibit B hereto, including the
     certifications in item (2) thereof.

          (iv)  Transfer and Exchange of Beneficial Interests in a Restricted
     Global Note for Beneficial Interests in the Unrestricted Global Note. A

     holder thereof for a beneficial interest in an Unrestricted Global Note or
     transferred to a Person who takes delivery thereof in the form of a
     beneficial interest in an Unrestricted Global Note if the exchange or
     transfer complies with the requirements of Section 2.06(b)(ii) above and:

     holder in the form of Exhibit C hereto, including the certifications in

     effect that such exchange or transfer is in compliance with the Securities
     Act and that the restrictions on transfer contained herein and in the

     compliance with the Securities Act.

          If any such transfer is effected pursuant to subparagraph (B) or (D)
above at a time when an Unrestricted Global Note has not yet been issued, the
Company shall issue and, upon receipt of an Authentication Order in accordance
with Section 2.02 hereof, the Trustee shall authenticate one or more
Unrestricted Global Notes in an aggregate principal amount equal to the
aggregate principal amount of beneficial interests transferred pursuant to
subparagraph (B) or (D) above.

with Section 2.11 hereof. At any time prior to such cancellation, if any

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

          (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).

     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

     Note so selected for redemption in whole or in part, except the unredeemed
     portion of any Note being redeemed in part or (c) to register the transfer
     of or to exchange a Note between a record date and the next succeeding
     Interest Payment Date.

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

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(a) 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 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.

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.

Section 2.14.     Issuance of Additional Notes.

          The Company shall be entitled to issue Additional Notes under this
Indenture which shall have identical terms as the Initial Notes issued on the
date hereof, other than with respect to the date of issuance, issue price, and
amount of interest payable on the first payment date applicable thereto;
provided that such issuance is not prohibited by Section 4.09. The Initial Notes
issued on the date hereof, any Additional Notes and all Exchange Notes issued in
exchange therefor, and the Shelf Registration Notes shall be treated as a single
class for all purposes under this Indenture.

                            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:

                                       36
<PAGE>

     (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 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

                                       37
<PAGE>

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.

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 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 April 15, 2005, 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 108.625% 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.

                                       38
<PAGE>

          (b) Except pursuant to the preceding paragraph, the Notes will not be
redeemable at the Company's option prior to April 15, 2007.

     After April 15, 2007, 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 April
15 of the years indicated below:

          YEAR                                            PERCENTAGE
          ----                                            ----------
          2007.........................................   104.313%
          2008.........................................   102.875%
          2009.........................................   101.438%
          2010 and thereafter..........................   100.00%

          (c) Any redemption pursuant to this Section 3.07 shall be made
pursuant to the provisions of Section 3.01 through 3.06 hereof.

SECTION 3.08.     MANDATORY REDEMPTION.

          The Company shall not be required to make mandatory redemption or
sinking fund payments with respect to the Notes.

SECTION 3.09.     OFFER TO PURCHASE BY APPLICATION OF EXCESS PROCEEDS.

          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:

                                       39
<PAGE>

     (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;

     (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.

                                   COVENANTS

SECTION 4.01.     PAYMENT OF NOTES.

          The Company or a Guarantor shall pay or cause to be paid the principal
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
the date due if the Paying Agent, if other than the Company or a Subsidiary
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,

manner on the dates and in the amounts set forth in the Registration Rights
Agreement.

          The Company or a Guarantor shall pay interest (including post-petition
interest in any proceeding under any Bankruptcy Law) on overdue principal at the
rate equal to 1% per annum in excess of the then applicable interest rate on the
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.

          The Company shall maintain in the Borough of Manhattan, the City of
New York, an office or agency (which may be an office of the Trustee or an
affiliate of the Trustee, Registrar or co-registrar) where Notes 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 agency. If at any
time the Company shall fail to maintain any such required 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. 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
2.03.

of filing such reports with the SEC:

          (i) all quarterly and annual financial information that would be
     required to be contained in a filing with the SEC on Forms 10-Q and 10-K if
     the Company were required to file such Forms, including a "Management's
     Discussion and Analysis of Financial Condition and

<PAGE>

     Results of Operations" 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
     SEC on Form 8-K if the Company were required to file such reports.

          If the Company has designated any of its Subsidiaries as Unrestricted
Subsidiaries, then the quarterly and annual financial information required by
the preceding paragraph shall include a reasonably detailed presentation, either
on the face of the financial statements or in the footnotes thereto, and in
Management's Discussion and Analysis of Financial Condition and Results of
Operations, of the financial condition and results of operations of the Company
and its Restricted Subsidiaries separate from the financial condition and
results of operations of the Unrestricted Subsidiaries of the Company.

          In addition, following consummation of the Exchange Offer, whether or
not required by the SEC, the Company shall file a copy of all of the information
and reports referred to in clauses (i) and (ii) above with the SEC for public
availability within the time periods specified in the SEC's rules and
regulations (unless the SEC will not accept such a filing) and make such

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

Securities Act. Reports and other filings made by DASI that include all of the
information referred to in clauses (i) and (ii) above with respect to DASI and
its consolidated subsidiaries shall be deemed to satisfy the obligations of the
Company and/or the Guarantors set forth above as long as such reports and
filings include the information required by Rule 3-10 of S-X; provided that DASI
does not have any business operations other than those conducted through the
Company.

SECTION 4.04.     COMPLIANCE CERTIFICATE.

     (a)  The Company and each Guarantor (to the extent that such Guarantor is
so required under the TIA) shall deliver to the Trustee, within 90 days after
the end of each fiscal year, an Officers' Certificate stating that a review of
the activities of the Company and its Subsidiaries during the preceding fiscal
year has been made under the supervision of the signing Officers with a view to
determining whether the Company has kept, observed, performed and fulfilled its
obligations under this Indenture, and further stating, as to each such Officer
signing such certificate, that to the best of his or her knowledge the Company
has kept, observed, performed and fulfilled each and every covenant contained in
this Indenture and is not in default in the performance or observance of any of
the terms, provisions and conditions of this Indenture (or, if a Default or
Event of Default shall have occurred, describing all such Defaults or Events of
Default of which he or she may have knowledge and what action the Company is
taking or proposes to take with respect thereto) and that to the best of his or
her knowledge no event has occurred and remains in existence by reason of which

prohibited or if such event has occurred, a description of the event and what
action the Company is taking or proposes to take with respect thereto. For
purposes of this paragraph, such compliance shall be determined without regard
to any period of grace or requirement of notice under this Indenture.

     (b)  So long as not contrary to the then current recommendations of the
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

                                       42
<PAGE>

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 Trustee, forthwith upon any Officer becoming aware of any Default
or Event of Default, an Officers' Certificate specifying such Default or Event
of Default and what action the Company is taking or proposes to take with
respect thereto.

SECTION 4.05.     TAXES.

          The Company shall pay, and shall cause each of its Subsidiaries to
pay, prior to delinquency, all material taxes, assessments, and governmental
levies except such as are contested in good faith and by appropriate proceedings
or where the failure to effect such payment is not adverse in any material
respect 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.

SECTION 4.07.     RESTRICTED PAYMENTS.

          The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly:

          (i) declare or pay any dividend or make any other payment or
     distribution on account of the Company's or any of its Restricted
     Subsidiaries' Equity Interests (including, without limitation, any payment
     in connection with any merger or consolidation involving the Company or any
     of its Restricted Subsidiaries) or to the direct or indirect holders of the
     Company's or any of its Restricted Subsidiaries' Equity Interests in their
     capacity as such (other than dividends or distributions payable in Equity
     Interests (other than Disqualified Stock) of the Company or to the Company
     or a Restricted Subsidiary of the Company);

          (ii) purchase, redeem or otherwise acquire or retire for value

<PAGE>

          (iv) make any Restricted Investment (all such payments and other
     actions set forth in clauses (i) through (iv) above being collectively
     referred to as "Restricted Payments"), unless, at the time of and after
     giving effect to such Restricted Payment:

          (i) no Default or Event of Default shall have occurred and be
     continuing or would occur as a consequence thereof; and

          (ii) the Company would, at the time of such Restricted Payment and
     after giving pro forma effect thereto as if such Restricted Payment had
     been made at the beginning of the applicable four-quarter period, have been
     permitted to incur at least $1.00 of additional Indebtedness pursuant to
     the Fixed Charge Coverage Ratio test set forth in the first paragraph of
     Section 4.09 hereof; and

          (iii) such Restricted Payment, together with the aggregate amount of
     all other Restricted Payments made by the Company and its Restricted
     Subsidiaries after the 9% Notes Original Issue Date (excluding Restricted
     Payments permitted by clauses (ii), (iii) and (iv) of the next succeeding
     paragraph), is less than the sum, without duplication, of

                (A) 50% of the Consolidated Net Income of the Company for the
     period (taken as one accounting period) from March 31, 1999 to the end of
     the Company's most recently ended fiscal quarter for which internal
     financial statements are available at the time of such Restricted Payment
     (or, if such Consolidated Net Income for such period is a deficit, less
     100% of such deficit), plus

                (B) 100% of the aggregate net cash proceeds or fair market value
     of Productive Assets received by the Company since the 9% Notes Original
     Issue Date as a contribution to its common equity capital or from the issue
     or sale of Equity Interests of the Company (other than Disqualified Stock)
     or from the issue or sale of convertible or exchangeable Disqualified Stock
     or convertible or exchangeable debt securities of the Company that have
     been converted into or exchanged for such Equity Interests (other than
     Equity Interests (or Disqualified Stock or debt securities) sold to a
     Subsidiary of the Company), plus

                (C) to the extent that any Restricted Investment that was made
     after the date of this Indenture is sold for cash or otherwise liquidated
     or repaid for cash, the lesser of (i) the cash return of capital with

     consists of cash or Productive Assets) as of the date of such
     redesignation.

So long as no Default has occurred and is continuing or would be caused thereby,
the preceding provisions shall not prohibit:

          (i) the payment of any dividend within 60 days after the date of

Directors' determination must be based upon an opinion or appraisal issued by an
accounting, appraisal or investment banking firm of national standing if the
fair market value exceeds $10.0 million. Not later than the date of making any

Certificate stating that such Restricted Payment is permitted and setting forth
the basis upon which the calculations required by this Section 4.07 were
computed, together with a copy of any fairness opinion or appraisal required by
this Indenture.

SECTION 4.08.     DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING RESTRICTED
                  SUBSIDIARIES.

          The Company shall not, and shall not permit any of its Restricted

          (v) any instrument governing Indebtedness or Capital Stock of a Person
     acquired by the Company or any of its Restricted Subsidiaries as in effect
     at the time of such acquisition (except to the extent such Indebtedness was
     incurred in connection with or in contemplation of such acquisition), which
     encumbrance or restriction is not applicable to any Person, or the
     properties or assets of any Person, other than the Person, or the property
     or assets of the Person, so acquired, provided that, in the case of
     Indebtedness, such Indebtedness was permitted by the terms of this
     Indenture to be incurred;

          (vi) customary non-assignment provisions in leases entered into in the
     ordinary course of business and consistent with past practices;

          (vii) purchase money obligations for property acquired in the ordinary
     course of business that impose restrictions on the property so acquired of
     the nature described in clause (iii) of the preceding paragraph;

          (viii) any agreement for the sale or other disposition of a Restricted
     Subsidiary that restricts distributions by that Restricted Subsidiary

     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

     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 Restricted
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 Restricted 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"):

          (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 $550.0 million less the aggregate amount of all
     Net Proceeds of Asset Sales applied by the Company or any of its Restricted
     Subsidiaries to repay any Indebtedness under the Credit Facilities and to
     effect a corresponding commitment reduction thereunder pursuant to Section
     4.10 of this Indenture;

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

                                       48
<PAGE>

          (iii) the incurrence by the Company and the Guarantors of Indebtedness
     represented by the Initial Notes and the related Guaranties, the Exchange
     Notes and the related Guaranties to be issued pursuant to the Registration
     Rights Agreement and the Shelf Registration Notes and the related
     Guaranties to be issued pursuant to the Registration Rights Agreement;

          (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 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;

                                       49
<PAGE>

          (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;

          (xiv) the incurrence by a Securitization Entity of Indebtedness in a
     Qualified Securitization Transaction that is Non-Recourse Debt (except for

          (xv) Indebtedness of the Company evidenced by promissory notes
     subordinated to the 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

<PAGE>
                  The Company will not incur any indebtedness (including
Permitted Debt) that is contractually subordinated in right of payment to any
other Indebtedness of the Company unless such Indebtedness is also contractually
subordinated in right of payment to the Notes on substantially identical terms,
provided that no Indebtedness of the Company will be deemed to be contractually
subordinated in right of payment to any other Indebtedness of the Company solely
by virtue of being unsecured.

                  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 (other than contingent liabilities and
         liabilities that are by their terms subordinated to the Notes or any
         related Subsidiary Guaranty) that are expressly assumed by the
         transferee of any such assets;

                           (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

                                       51
<PAGE>
         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 the Company's secured Indebtedness (other than
         subordinated Indebtedness) under the Credit Agreement and, if such
         Indebtedness 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;

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

                  (v) any combination of the foregoing; and/or

                  (vi) to redeem the Notes with the Net Proceeds of such Asset
         Sale pursuant to Section 3.07 of this Indenture.

                  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
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

                                       52
<PAGE>

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;

                  (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;

                                       53
<PAGE>

                  (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 without making, or causing such Subsidiary to
make, effective provision for securing the Notes or, in respect of Liens on any
Guarantor's property or assets, any Guarantee of such Guarantor, (x) equally and
ratably with such Indebtedness as to such property or assets for so long as such
Indebtedness will be so secured or (y) in the event such Indebtedness is
subordinated Indebtedness, prior to such Indebtedness as to such property or
assets for so long as such Indebtedness will be so secured.

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,

                                       54
<PAGE>

                  (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 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

                                       55
<PAGE>

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 secured Indebtedness outstanding under the Credit
Agreement or obtain the requisite consents, if any, under the Credit Agreement
to 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 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

                                       56
<PAGE>

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 4.17 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 4.18 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 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.

dispose of all or substantially all of the properties or assets of the Company
and its Restricted Subsidiaries taken as a whole, in one or more related

         or existing under the laws of the United States, any state thereof or

         made 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

                                       57
<PAGE>

                  (iv) the Company or the Person formed by or surviving any such

         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.

                  In addition, the Company shall not, directly or indirectly,
lease all or substantially all of its properties or assets, in one or more
related transactions, to any other Person. The provisions of this Section 5.01
shall not 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,

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 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.

         created after the date hereof, if that default:

                           (A) is caused by a failure to pay principal of, or

                           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,
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

                                       60
<PAGE>

(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
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

                                       61
<PAGE>

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) 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

                                       62
<PAGE>

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.

                                   ARTICLE 7

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

         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.

         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.

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

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.

                                       63
<PAGE>

         (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

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

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

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

                                       64
<PAGE>

trustee or resign. Any Agent may do the same with like rights and duties. The
Trustee is also subject to Sections 7.10 and 7.11 hereof.

SECTION 7.04 TRUSTEE'S DISCLAIMER.

                  The Trustee shall not be responsible for and makes no
representation as to the validity or adequacy of this Indenture 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 October 1 beginning with the October
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)

                                       65
<PAGE>

or liability in connection with the exercise or performance of any of its powers
or duties hereunder, except to the extent any such loss, liability or expense
may be attributable to its negligence or bad faith. The Trustee shall notify the
Company 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.

                  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

                                       66
<PAGE>

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.

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 and
4.17 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, 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

                                       68
<PAGE>

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;

         (e) such Legal Defeasance or Covenant Defeasance shall not result in a
breach or violation of, or constitute a default under any 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

                                       69
<PAGE>

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; and

         (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.

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.

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.

                                       70
<PAGE>

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 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.

                                       71

<PAGE>
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). 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.

                  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

                                       72
<PAGE>

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;

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

         (j) contractually subordinate any Note or any Guarantee to any other
Indebtedness or other obligations of the Company or any Guarantor.

SECTION 9.03. COMPLIANCE WITH TRUST INDENTURE ACT.

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

SECTION 9.04. REVOCATION AND EFFECT OF CONSENTS.

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

                                       73
<PAGE>

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.
                                   GUARANTIES

SECTION 10.01. GUARANTY.

                  Subject to this Article 10, 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 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

                                       74
<PAGE>

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 10.02. 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 10 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 10, result in the obligations of such Guarantor
under its Guaranty not constituting a fraudulent transfer or conveyance.

SECTION 10.03. EXECUTION AND DELIVERY OF GUARANTY.

                  To evidence its Guaranty set forth in Section 10.01, each
Guarantor hereby agrees that a 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 10.01 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
4.16 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 4.16 hereof and this Article 10, to the extent
applicable.

SECTION 10.04. GUARANTORS MAY CONSOLIDATE, ETC., ON CERTAIN TERMS.

                  Except as otherwise provided in Section 10.05, 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

                                       75
<PAGE>

         (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

the applicable provisions of this Indenture, including without limitation
Section 4.10 hereof;

         (b) in connection with any sale of all of the capital stock of a

is a Guarantor as an Unrestricted Subsidiary;

         (d) if that Guarantor ceases to guarantee, pledge any of its assets or
otherwise provide direct or indirect credit support for any Indebtedness or
other obligations of DASI, the Company or any Restricted Subsidiary; or
