         (v)      that any Holder will be entitled to withdraw its election, not

                  Registrable Securities delivered for exchange and a statement
                  that such Holder is withdrawing its election to have such
                  Securities exchanged.

                  As a condition to participating in the Exchange Offer, a
Holder will be required to represent to the Company and the Guarantors that (i)
any Exchange Securities to be received by it will be acquired in the ordinary
course of its business, (ii) at the time of the commencement of the Exchange

                                       5
<PAGE>

"affiliate" (within the meaning of Rule 405 under Securities Act) of the Company
or any Guarantor and (iv) if such Holder is a broker-dealer that will receive
Exchange Securities for its own account in exchange for Registrable Securities
that were acquired as a result of market-making or other trading activities,
then such Holder will deliver a Prospectus in connection with any resale of such
Exchange Securities.

                  As soon as practicable after the last Exchange Date, the
Company and the Guarantors shall:

          (i)     accept for exchange Registrable Securities or portions thereof
                  validly tendered and not properly withdrawn pursuant to the
                  Exchange Offer; and

          (ii)    deliver, or cause to be delivered, to the Trustee for
                  cancellation all Registrable Securities or portions thereof so
                  accepted for exchange by the Company and issue, and cause the
                  Trustee to promptly authenticate and deliver to each Holder,
                  Exchange Securities equal in principal amount to the principal
                  amount of the Registrable Securities surrendered by such
                  Holder.

                  The Company and the Guarantors shall use their reasonable best
efforts to complete the Exchange Offer as provided above and shall comply with
the applicable requirements of the Securities Act, the Exchange Act and other
applicable laws and regulations in connection with the Exchange Offer. The
Exchange Offer shall not be subject to any conditions, other than that the
Exchange Offer does not violate any applicable law or applicable interpretations
of the Staff of the SEC.

                  (b)      In the event that (i) the Company and the Guarantors
determine that the Exchange Offer Registration provided for in Section 2(a)
above is not available or may not be completed as soon as practicable after the
last Exchange Date because it would violate any applicable law or applicable
interpretations of the Staff of the SEC, (ii) the Exchange Offer is not for any
other reason completed by October 6, 2004 or (iii) upon completion of the
Exchange Offer any Initial Purchaser shall so request in connection with any
offering or sale of Registrable Securities not eligible to be exchanged for
Exchange Securities in the Exchange Offer held by it following the consummation
of the Exchange Offer, the Company and the Guarantors shall use their reasonable
best efforts to cause to be filed as soon as practicable after such
determination, date or request, as the case may be, a Shelf Registration
Statement providing for the sale of all the Registrable Securities by the
Holders thereof and to have such Shelf Registration Statement declared effective
by the SEC.

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

                                       6
<PAGE>

respect to offers and sales of Registrable Securities held by the Initial
Purchasers after completion of the Exchange Offer.

                  The Company and the Guarantors agree to use their reasonable
best efforts to keep the Shelf Registration Statement continuously effective
until the expiration of the period referred to in Rule 144(k) under the
Securities Act with respect to the Registrable Securities or such shorter period
that will terminate when all the Registrable Securities covered by the Shelf
Registration Statement have been sold pursuant to the Shelf Registration
Statement (the "Shelf Effectiveness Period"). The Company and the Guarantors
further agree to supplement or amend the Shelf Registration Statement and the
related Prospectus if required by the rules, regulations or instructions
applicable to the registration form used by the Company for such Shelf
Registration Statement or by the Securities Act or by any other rules and
regulations thereunder for shelf registration or if reasonably requested by a
Holder of Registrable Securities with respect to information relating to such
Holder, and to use their reasonable best efforts to cause any such amendment to
become effective and such Shelf Registration Statement and Prospectus to become
usable as soon as thereafter practicable. The Company and the Guarantors agree
to furnish to the Holders of Registrable Securities copies of any such
supplement or amendment promptly after its being used or filed with the SEC.

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

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

                  In the event that either the Exchange Offer is not completed
or the Shelf Registration Statement, if required hereby, is not declared
effective on or prior to October 6, 2004 (the "Target Registration Date"), the
interest rate on the Registrable Securities will be increased by (i) 0.25% per
annum for the first 90-day period immediately following the Target Registration
Date and (ii) an additional 0.25% per annum with respect to each subsequent
90-day period, in each case until the Exchange Offer is completed or the Shelf
Registration Statement, if required hereby, is declared effective by the SEC or
the Securities become freely tradable under the Securities Act, up to a maximum
of 1.00% per annum of additional interest.

                  If the Shelf Registration Statement has been declared
effective and thereafter either ceases to be effective or the Prospectus
contained therein ceases to be usable at any time during the Shelf Effectiveness
Period, and such failure to remain effective or usable exists for more than 30
days (whether or not consecutive) in any 12-month period, then the interest rate
on the Registrable Securities will be increased by 1.00% per annum commencing on
the 31st day in such 12-month period and ending on such date that the Shelf

                                       7
<PAGE>

Registration Statement has again been declared effective or the Prospectus again
becomes usable.

                  (e)      Without limiting the remedies available to the
Initial Purchasers and the Holders, the Company and the Guarantors acknowledge
that any failure by the Company or the Guarantors to comply with their
obligations under Section 2(a) and Section 2(b) hereof may result in material
irreparable injury to the Initial Purchasers or the Holders for which there is
no adequate remedy at law, that it will not be possible to measure damages for
such injuries precisely and that, in the event of any such failure, the Initial
Purchasers or any Holder may obtain such relief as may be required to
specifically enforce the Company's and the Guarantors' obligations under Section
2(a) and Section 2(b) hereof.

                  3.       Registration Procedures. In connection with their
obligations pursuant to Section 2(a) and Section 2(b) hereof, the Company and
the Guarantors shall as expeditiously as possible

                  (a)      prepare and file with the SEC a Registration
         Statement on the appropriate form under the Securities Act, which form
         (x) shall be selected by the Company and the Guarantors, (y) shall, in
         the case of a Shelf Registration, be available for the sale of the
         Registrable Securities by the selling Holders thereof and (z) shall
         comply as to form in all material respects with the requirements of the
         applicable form and include all financial statements required by the
         SEC to be filed therewith; and use their reasonable best efforts to
         cause such Registration Statement to become effective and remain
         effective for the applicable period in accordance with Section 2
         hereof;

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

                  (c)      in the case of a Shelf Registration, furnish to each
         Holder of Registrable Securities, to counsel for the Initial
         Purchasers, to counsel for such Holders and to each Underwriter of an

         charge, as many copies of each Prospectus, including each preliminary
         Prospectus, and any amendment or supplement thereto, in order to
         facilitate the sale or other disposition of the Registrable Securities

         such Prospectus and any amendment or supplement thereto in accordance
         with applicable law by each of the selling Holders of Registrable
         Securities and any such Underwriters in connection with the offering
         and sale of the Registrable Securities covered by and in the manner

                                       8
<PAGE>

         described in such Prospectus or any amendment or supplement thereto in
         accordance with applicable law;

                  (d)      if necessary, use their reasonable best efforts to
         register or qualify the Registrable Securities under all applicable
         state securities or blue sky laws of such jurisdictions as any Holder
         of Registrable Securities covered by a Registration Statement shall
         reasonably request in writing by the time the applicable Registration
         Statement is declared effective by the SEC; cooperate with the Holders
         in connection with any filings required to be made with the National

         Holder to complete the disposition in each such jurisdiction of the
         Registrable Securities owned by such Holder; provided, however, that
         neither the Company nor any Guarantor shall be required to (i) qualify

         in any such jurisdiction where it would not otherwise be required to so
         qualify, (ii) file any general consent to service of process in any

         for the Initial Purchasers promptly and, if requested by any such
         Holder or counsel, confirm such advice in writing (i) when a

         effective, (iii) of the issuance by the SEC or any state securities
         authority of any stop order suspending the effectiveness of a

         Registrable Securities for sale in any jurisdiction or the initiation
         of any proceeding for such purpose, (v) of the happening of any event
         during the period a Shelf Registration Statement is effective that
         makes any statement made in such Registration Statement or the related
         Prospectus untrue in any material respect or that requires the making
         of any changes in such Registration Statement or Prospectus in order to
         make the statements therein not misleading and (vi) of any
         determination by the Company or any Guarantor that a post-effective
         amendment to a Registration Statement would be appropriate;

                  (f)      use their reasonable best efforts to obtain the
         withdrawal of any order suspending the effectiveness of a Registration
         Statement at the earliest possible

                                       9
<PAGE>

         moment and provide immediate notice to each Holder of the withdrawal of
         any such order;

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

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

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

                  (j)      a reasonable time prior to the filing of any
         Registration Statement, any Prospectus, any amendment to a Registration
         Statement or amendment or supplement to a Prospectus or of any document
         that is to be incorporated by reference into a Registration Statement
         or a Prospectus after initial filing of a Registration Statement,
         provide copies of such document to the Initial Purchasers and their
         counsel (and, in the case of a Shelf Registration Statement, to the
         Holders of Registrable Securities and their counsel) and make such of
         the representatives of the Company and the Guarantors as shall be
         reasonably requested by the Initial Purchasers or their counsel (and,
         in the case of a Shelf Registration Statement, the Holders of
         Registrable Securities or their counsel) available for discussion of
         such document; and the Company and the Guarantors shall not, at any
         time after initial filing of a Registration Statement, file any
         Prospectus, any amendment of or supplement to a Registration Statement
         or a Prospectus, or any document that is to be incorporated by
         reference into a Registration Statement or a Prospectus, of which the
         Initial Purchasers and their counsel (and, in the case of a Shelf
         Registration

                                       10
<PAGE>

         Statement, the Holders of Registrable Securities and their counsel)
         shall not have previously been advised and furnished a copy or to which
         the Initial Purchasers or their counsel (and, in the case of a Shelf
         Registration Statement, the Holders or their counsel) shall object;

                  (k)      obtain a CUSIP number for all Exchange Securities or
         Registrable Securities, as the case may be, not later than the
         effective date of a Registration Statement;

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

                  (m)      in the case of a Shelf Registration, make available
         for inspection by a representative of the Holders of the Registrable
         Securities (an "Inspector"), any Underwriter participating in any
         disposition pursuant to such Shelf Registration Statement, and
         attorneys and accountants designated by the Holders (but in such event,
         only one law firm and one accounting firm to represent the Holders at
         the Company's and the Guarantor's expense), at reasonable times and in
         a reasonable manner, all pertinent financial and other records,
         documents and properties of the Company and the Guarantors, and cause
         the respective officers, directors and employees of the Company and the
         Guarantors to supply all information reasonably requested by any such
         Inspector, Underwriter, attorney or accountant in connection with a
         Shelf Registration Statement; provided, however, that if any such
         information is identified by the Company or any Guarantor as being
         confidential or proprietary, each Person receiving such information
         shall take such actions as are reasonably necessary to protect the
         confidentiality of such information to the extent such action is
         otherwise not inconsistent with, an impairment of or in derogation of
         the rights and interests of any Inspector, Holder or Underwriter);

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

                  (o)      if reasonably requested by any Holder of Registrable
         Securities covered by a Registration Statement, promptly incorporate in
         a Prospectus supplement or post-effective amendment such information
         with respect to such Holder as such Holder reasonably requests to be
         included therein and make all required filings of such Prospectus
         supplement or such post-effective amendment as

                                       11
<PAGE>

         soon as the Company has received notification of the matters to be
         incorporated in such filing; and

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

                  In the case of a Shelf Registration Statement, the Company may
require, as a condition to including such Holder's Registrable Securities in
such Shelf Registration Statement, each Holder of Registrable Securities to
furnish to the Company such information regarding such Holder and the proposed
disposition by such Holder of such Registrable Securities as the Company and the
Guarantors may from time to time reasonably request in writing.

                  In the case of a Shelf Registration Statement, each Holder of
Registrable Securities agrees that, upon receipt of any notice from the Company
and the Guarantors of the happening of any event of the kind described in
Section 3(e)(iii) or 3(e)(v) hereof, such Holder will forthwith discontinue
disposition of Registrable Securities pursuant to a

                                       12
<PAGE>

Registration Statement until such Holder's receipt of the copies of the
supplemented or amended Prospectus contemplated by Section 3(i) hereof and, if
so directed by the Company and the Guarantors, such Holder will deliver to the
Company and the Guarantors all copies in its possession, other than permanent
file copies then in such Holder's possession, of the Prospectus covering such
Registrable Securities that is current at the time of receipt of such notice.

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

                  The Holders of Registrable Securities covered by a Shelf
Registration Statement who desire to do so may sell such Registrable Securities
in an Underwritten Offering. In any such Underwritten Offering, the investment
banker or investment bankers and manager or managers (the "Underwriters") that
will administer the offering will be selected by the Majority Holders of the
Registrable Securities included in such offering.

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

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

                  (b)      In light of the above, and notwithstanding the other
provisions of this Agreement, the Company and the Guarantors agree to amend or
supplement the Prospectus contained in the Exchange Offer Registration
Statement, as would otherwise be contemplated by Section 3(i), for a period of
up to 180 days after the last Exchange Date (as

                                       13
<PAGE>

such period may be extended pursuant to the penultimate paragraph of Section 3
of this Agreement), if requested by the Initial Purchasers or by one or more
Participating Broker-Dealers, in order to expedite or facilitate the disposition
of any Exchange Securities by Participating Broker-Dealers consistent with the
positions of the Staff recited in Section 4(a) above. The Company and the
Guarantors further agree that Participating Broker-Dealers shall be authorized
to deliver such Prospectus during such period in connection with the resales
contemplated by this Section 4.

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

                  5.       Indemnification and Contribution. (a) The Company
and each Guarantor, jointly and severally, agree to indemnify and hold harmless
each Initial Purchaser and each Holder, their respective affiliates, directors
and officers and each Person, if any, who controls any Initial Purchaser or any
Holder within the meaning of Section 15 of the Securities Act or Section 20 of
the Exchange Act, from and against any and all losses, claims, damages and
liabilities (including, without limitation, legal fees and other expenses
incurred in connection with any suit, action or proceeding or any claim
asserted, as such fees and expenses are incurred), joint or several, that arise
out of, or are based upon, any untrue statement or alleged untrue statement of a
material fact contained in any Registration Statement or any Prospectus or any
omission or alleged omission to state therein a material fact required to be
stated therein or necessary in order to make the statements therein, in the
light of the circumstances under which they were made, not misleading, except
insofar as such losses, claims, damages or liabilities arise out of, or are
based upon, any untrue statement or omission or alleged untrue statement or
omission made in reliance upon and in conformity with any information relating
to any Initial Purchaser or any Holder furnished to the Company in writing
through J.P. Morgan Securities Inc. or any selling Holder expressly for use
therein. In connection with any Underwritten Offering permitted by Section 3,
the Company and the Guarantors, jointly and severally, will also indemnify the
Underwriters, if any, selling brokers, dealers and similar securities industry
professionals participating in the distribution, their respective affiliates and
each Person who controls such Persons (within the meaning of the Securities Act
and the Exchange Act) to the same extent as provided above with respect to the
indemnification of the Holders, if requested in connection with any Registration
Statement.

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

                                       14
<PAGE>

and in conformity with any information relating to such Holder furnished to the
Company in writing by such Holder expressly for use in any Registration
Statement and any Prospectus.

                  (c)      If any suit, action, proceeding (including any
governmental or regulatory investigation), claim or demand shall be brought or
asserted against any Person in respect of which indemnification may be sought
pursuant to either paragraph (a) or (b) above, such Person (the "Indemnified
Person") shall promptly notify the Person against whom such indemnification may
be sought (the "Indemnifying Person") in writing; provided, however, that the
failure to notify the Indemnifying Person shall not relieve it from any
liability that it may have under this Section 5 except to the extent that it has
been materially prejudiced (through the forfeiture of substantive rights or
defenses) by such failure; and provided, further, however, that the failure to
notify the Indemnifying Person shall not relieve it from any liability that it
may have to an Indemnified Person otherwise than under this Section 5. If any
such proceeding shall be brought or asserted against an Indemnified Person and
it shall have notified the Indemnifying Person thereof, the Indemnifying Person
shall retain counsel reasonably satisfactory to the Indemnified Person to
represent the Indemnified Person and any others entitled to indemnification
pursuant to this Section 5 that the Indemnifying Person may designate in such
proceeding and shall pay the fees and expenses of such counsel related to such
proceeding, as incurred. In any such proceeding, any Indemnified Person shall
have the right to retain its own counsel, but the fees and expenses of such
counsel shall be at the expense of such Indemnified Person unless (i) the
Indemnifying Person and the Indemnified Person shall have mutually agreed to the
contrary; (ii) the Indemnifying Person has failed within a reasonable time to
retain counsel reasonably satisfactory to the Indemnified Person; (iii) the
Indemnified Person shall have reasonably concluded that there may be legal
defenses available to it that are different from or in addition to those
available to the Indemnifying Person; or (iv) the named parties in any such
proceeding (including any impleaded parties) include both the Indemnifying
Person and the Indemnified Person and representation of both parties by the same
counsel would be inappropriate due to actual or potential differing interests
between them. It is understood and agreed that the Indemnifying Person shall
not, in connection with any proceeding or related proceeding in the same
jurisdiction, be liable for the fees and expenses of more than one separate firm
(in addition to any local counsel) for all Indemnified Persons, and that all
such fees and expenses shall be reimbursed as they are incurred. Any such
separate firm (x) for any Initial Purchaser, its affiliates, directors and
officers and any control Persons of such Initial Purchaser shall be designated
in writing by J.P. Morgan Securities Inc., (y) for any Holder, its affiliates,
directors and officers and any control Persons of such Holder shall be
designated in writing by the Majority Holders and (z) in all other cases shall
be designated in writing by the Company. The Indemnifying Person shall not be
liable for any settlement of any proceeding effected without its written
consent, but if settled with such consent or if there be a final judgment for
the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified
Person from and against any loss or liability by reason of such settlement or
judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified
Person shall have requested that an Indemnifying Person reimburse the
Indemnified Person for fees and expenses of counsel as contemplated by this
paragraph, the Indemnifying Person shall be liable for any settlement of any
proceeding effected without its written consent if (i) such

                                       15
<PAGE>

settlement is entered into more than 30 days after receipt by the Indemnifying
Person of such request and (ii) the Indemnifying Person shall not have
reimbursed the Indemnified Person in accordance with such request prior to the
date of such settlement. No Indemnifying Person shall, without the written
consent of the Indemnified Person, effect any settlement of any pending or
threatened proceeding in respect of which any Indemnified Person is or could
have been a party and indemnification could have been sought hereunder by such
Indemnified Person, unless such settlement (A) includes an unconditional release
of such Indemnified Person, in form and substance reasonably satisfactory to
such Indemnified Person, from all liability on claims that are the subject
matter of such proceeding and (B) does not include any statement as to or any
admission of fault, culpability or a failure to act by or on behalf of any
Indemnified Person.

                  (d)      If the indemnification provided for in paragraphs (a)
and (b) above is unavailable to an Indemnified Person or insufficient in respect
of any losses, claims, damages or liabilities referred to therein, then each
Indemnifying Person under such paragraph, in lieu of indemnifying such
Indemnified Person thereunder, shall contribute to the amount paid or payable by
such Indemnified Person as a result of such losses, claims, damages or
liabilities (i) in such proportion as is appropriate to reflect the relative
benefits received by the Company and the Guarantors from the offering of the
Securities and the Exchange Securities, on the one hand, and by the Holders from
receiving Securities or Exchange Securities registered under the Securities Act,
on the other hand, or (ii) if the allocation provided by clause (i) is not
permitted by applicable law, in such proportion as is appropriate to reflect not
only the relative benefits referred to in clause (i) but also the relative fault
of the Company and the Guarantors on the one hand and the Holders on the other
in connection with the statements or omissions that resulted in such losses,
claims, damages or liabilities, as well as any other relevant equitable
considerations. The relative fault of the Company and the Guarantors on the one
hand and the Holders on the other shall be determined by reference to, among
other things, whether the untrue or alleged untrue statement of a material fact
or the omission or alleged omission to state a material fact relates to
information supplied by the Company and the Guarantors or by the Holders and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission.

                  (e)      The Company, the Guarantors and the Holders agree
that it would not be just and equitable if contribution pursuant to this Section
5 were determined by pro rata allocation (even if the Holders were treated as
one entity for such purpose) or by any other method of allocation that does not
take account of the equitable considerations referred to in paragraph (d) above.
The amount paid or payable by an Indemnified Person as a result of the losses,
claims, damages and liabilities referred to in paragraph (d) above shall be
deemed to include, subject to the limitations set forth above, any legal or
other expenses incurred by such Indemnified Person in connection with any such
action or claim. Notwithstanding the provisions of this Section 5, in no event
shall a Holder be required to contribute any amount in excess of the amount by
which the total price at which the Securities or Exchange Securities sold by
such Holder exceeds the amount of any damages that such Holder has otherwise
been required to pay by reason of such untrue or alleged

                                       16
<PAGE>

untrue statement or omission or alleged omission. No Person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any Person who was not guilty of such
fraudulent misrepresentation.

                  (f)      The remedies provided for in this Section 5 are not
exclusive and shall not limit any rights or remedies that may otherwise be
available to any Indemnified Person at law or in equity.

                  (g)      The indemnity and contribution provisions contained
in this Section 5 shall remain operative and in full force and effect regardless
of (i) any termination of this Agreement, (ii) any investigation made by or on
behalf of the Initial Purchasers or any Holder, their respective affiliates or
any Person controlling any Initial Purchaser or any Holder, or by or on behalf
of the Company or the Guarantors, their respective affiliates or the officers or
directors of or any Person controlling the Company or the Guarantors, (iii)
acceptance of any of the Exchange Securities and (iv) any sale of Registrable
Securities pursuant to a Shelf Registration Statement.

                  6.       General.

                  (a)      No Inconsistent Agreements. The Company and the
Guarantors represent, warrant and agree that (i) the rights granted to the
Holders hereunder do not in any way conflict with and are not inconsistent with
the rights granted to the holders of any other outstanding securities issued or
guaranteed by the Company or any Guarantor under any other agreement and (ii)
neither the Company nor any Guarantor has entered into, or on or after the date
of this Agreement will enter into, any agreement that is inconsistent with the
rights granted to the Holders of Registrable Securities in this Agreement or
otherwise conflicts with the provisions hereof.

                  (b)      Amendments and Waivers. The provisions of this
Agreement, including the provisions of this sentence, may not be amended,
modified or supplemented, and waivers or consents to departures from the
provisions hereof may not be given unless the Company and the Guarantors have
obtained the written consent of Holders of at least a majority in aggregate
principal amount of the outstanding Registrable Securities affected by such
amendment, modification, supplement, waiver or consent; provided, however, that
no amendment, modification, supplement, waiver or consent to any departure from
the provisions of Section 5 hereof shall be effective as against any Holder of
Registrable Securities unless consented to in writing by such Holder. Any

rights of other Holders hereunder.

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

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

                  (h)      Governing Law. This Agreement shall be governed by
and construed in accordance with the laws of the State of New York without
regard to the conflicts of law provisions thereof to the extent the application

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

Preferred Stock multiplied by the amount of such payment by (ii) the sum of all
such payments.

                  "Bankruptcy Law" means Title 11, United States Code or any

         to acquire, whether such right is exercisable immediately or only after
         the passage of time), directly or indirectly, of more than 50% of the

<PAGE>

         lease between the Company and a Wholly Owned Subsidiary; or

                  (iv)     the stockholders of the Company shall approve any
         plan or proposal for the liquidation or dissolution of the Company.

                  "Code" means the Internal Revenue Code of 1986, as amended.

                  "Company" means Trinity Industries, Inc., a Delaware

                  "Consolidated Assets" as of any date of determination means

                  "Consolidated Coverage Ratio" as of any date of determination
means the ratio of (i) the aggregate amount of EBITDA for the four most recent
fiscal quarters for which the Company has filed financial statements with the
SEC pursuant to the requirements of the Exchange Act prior to the date of such
determination to (ii) Consolidated Interest Expense for such four fiscal
quarters; provided, however, that:

                  (1)      if the Company or any Restricted Subsidiary has
         Incurred any Indebtedness since the beginning of such period that
         remains outstanding or if the transaction giving rise to the need to
         calculate the Consolidated Coverage Ratio is an Incurrence of
         Indebtedness, or both, EBITDA and Consolidated Interest Expense for
         such period shall be calculated after giving effect on a pro forma
         basis to such Indebtedness as if such Indebtedness has been Incurred on
         the first day of such period and the discharge of any other
         Indebtedness repaid, repurchased, defeased or otherwise discharged with
         the proceeds of such new Indebtedness or otherwise, as if such
         discharge had occurred on the first day of such period, except that, in
         making such calculation, Indebtedness Incurred under a revolving credit
         or similar arrangement to finance seasonal fluctuations in working
         capital needs shall be computed on the average daily balance of such
         Indebtedness during such period unless such Indebtedness is projected
         in the reasonable judgment of senior management of the Company to
         remain outstanding for a period in excess of 12 months from the date of
         Incurrence of such Indebtedness, in which case such Indebtedness will
         be assumed to have been Incurred on the first day of such coverage
         period;

                  (2)      if since the beginning of such period the Company or
         any Restricted Subsidiary shall have made any Asset Disposition, the
         EBITDA for such period shall be reduced by an amount equal to the
         EBITDA (if positive) directly attributable to the assets which are the
         subject of such Asset Disposition for such period, or increased by an
         amount equal to the EBITDA (if negative) directly attributable thereto
         for such period and Consolidated Interest Expense for such period shall
         be reduced by an amount equal to the Consolidated Interest Expense
         directly attributable to any Indebtedness of the Company or any
         Restricted Subsidiary repaid, repurchased, defeased or otherwise

                                      -4-
<PAGE>

         discharged with respect to the Company and its continuing Restricted
         Subsidiaries in connection with such Asset Disposition for such period
         (or, if the Capital Stock of any Restricted Subsidiary is sold, the
         Consolidated Interest Expense for such period directly attributable to
         the Indebtedness of such Restricted Subsidiary to the extent the
         Company and its continuing Restricted Subsidiaries are no longer liable
         for such Indebtedness after such sale);

                  (3)      if since the beginning of such period the Company or
         any Restricted Subsidiary (by merger or otherwise) shall have made an
         Investment in any person which becomes a Restricted Subsidiary or an
         acquisition of assets, including any acquisition of assets occurring in
         connection with a transaction causing a calculation to be made
         hereunder, which constitutes all or substantially all of an operating
         unit of a business (and for which financial information is available
         sufficient to permit calculations of EBITDA for such operating unit),
         EBITDA and Consolidated Interest Expense for such period shall be
         calculated after giving pro forma effect thereto (including the
         Incurrence of any Indebtedness) as if such Investment or acquisition
         occurred on the first day of such period; and

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

                  For purposes of this definition, whenever pro forma effect is
to be given to an acquisition of assets, the amount of income or earnings
relating thereto, and the amount of Consolidated Interest Expense associated
with any Indebtedness Incurred in connection therewith, the pro forma
calculations shall be determined in good faith by a responsible financial or
accounting officer of the Company. If any Indebtedness bears a floating rate of
interest and is being given pro forma effect, the interest on such Indebtedness
shall be calculated as if the rate in effect on the date of determination had
been the applicable rate for the entire period (taking into account any Hedging
Obligations applicable to such Indebtedness if such Hedging Obligations have a
remaining term in excess of 12 months). If any Indebtedness that bears interest
at a rate chosen at the option of the Company is being given pro forma effect,
the interest rate shall be calculated by applying such optional rate chosen by

                  Section 2.1. Form and Dating.

                  The Notes and the Trustee's certificate of authentication
thereof shall be substantially in the form of Exhibit A hereto, which is hereby
incorporated in and expressly made a part of this Indenture. The Exchange Notes
and the Trustee's certificate of authentication thereof shall be substantially
in the form of Exhibit B hereto, which is hereby incorporated in and expressly
made a part of this Indenture. The Notes may have notations, legends or
endorsements required by law, stock exchange rule or usage. The Company and the
Trustee shall approve the form of the Notes and any notation, legend or
endorsement on them. Each Note shall be dated the date of its authentication.

                  Notes offered and sold in reliance on Rule 144A shall be
issued initially in the form of one or more 144A Global Notes and Notes offered
and sold in reliance on Regulation S shall be issued initially in the form of
one or more Regulation S Global Notes, each substantially in the form set forth
in Exhibit A hereto, deposited with the Trustee, as custodian for the
Depository, duly executed by the Company and authenticated by the Trustee as
hereinafter provided and shall bear the legend set forth in Exhibit C hereto.

                  The initial offer and resale of the Notes shall not be to an
Institutional Accredited Investor. The Notes resold to Institutional Accredited
Investors in connection with the first transfer made pursuant to Section 2.16(a)
shall be issued initially in the form of a single permanent Global Note in
registered form, substantially in the form set forth in Exhibit A, deposited
with the Trustee, as custodian for the Depository, duly executed by the Company
(and having an

                                      -24-
<PAGE>

executed Subsidiary Guarantee from each of the Guarantors endorsed thereon) and
authenticated by the Trustee as hereinafter provided and shall bear the legend
set forth in Exhibit C hereto.

                  The aggregate principal amount of the Global Notes may from
time to time be increased or decreased by adjustments made on the records of the
Trustee, as custodian for the Depository, as hereinafter provided.

                  Section 2.2. Execution and Authentication.

                  Two Officers shall sign (each of whom shall, in each case,
have been duly authorized by all requisite corporate actions) the Notes for the
Company by manual or facsimile signature.

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

                  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 form of Trustee's
certificate of authentication to be borne by the Notes shall be substantially as
set forth in Exhibits A and B hereto.

                  The Trustee shall authenticate (i) Initial Notes that are 6
1/2% Senior Notes due 2014 for original issue on the Issue Date in an aggregate
principal amount not to exceed $300,000,000, or (ii) Unrestricted Notes from
time to time only in exchange for a like principal amount of Initial Notes, in
each case upon a written order of the Company in the form of an Officers'
Certificate. Each such written order shall specify the amount of Notes to be
authenticated and the date on which the Notes are to be authenticated, whether
the Notes are to be Initial Notes or Unrestricted Notes and whether the Notes
are to be issued as Physical Notes or Global Notes and such other information as
the Trustee may reasonably request. Additional Notes may be issued in accordance
with Section 2.17 and Unrestricted Notes may be issued in exchange for
Additional Notes that are Restricted Securities. Any such order or orders shall
specify the amount of the Notes to be authenticated and the date on which the
original issue of Notes is to be authenticated and, in the case of an issuance
of Additional Notes pursuant to Section 2.17 after the Issue Date, whether such
Additional Notes shall be issued as Initial Notes or Unrestricted Notes, shall
certify that such issuance will not be prohibited by Section 4.9.

                  The Trustee may appoint an authenticating agent acceptable to
the Company to authenticate Notes. Unless otherwise provided in the appointment,
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 authenticating agent has the same rights as an
Agent to deal with the Company or an Affiliate.

                  The Notes shall be issuable only in registered form without
coupons in denominations of $1,000 and any integral multiple thereof.

                  Section 2.3. 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
office or agency including the office or agency maintained by the Company
pursuant to Section 4.2 where Notes may be presented for payment ("Paying
Agent"). The 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 "Paying Agent" includes any additional paying
agent. The Company may change any Paying Agent, Registrar or co-registrar
without notice to any Holder. The Company shall notify the Trustee of the name
and address of any Agent not a party to this Indenture. If the Company fails to
appoint or maintain another entity as Registrar or Paying Agent, the Trustee
shall act as such. The Company or any of its Subsidiaries may act as Paying
Agent, Registrar or co-registrar.

                  The Company initially appoints the Trustee as Registrar and
Paying Agent in connection with the Notes.

                  Section 2.4. Paying Agent To Hold Money in Trust.

                  The Company (or any other obligor upon the Notes) shall
require each Paying Agent other than the Trustee 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 or interest on the
Notes, and will notify the Trustee of any Default by the Company (or any other
obligor upon the Notes) 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 (or any other obligor upon the Notes) at any time may
require a Paying Agent to pay all money held by it to the Trustee. Upon payment
over to the Trustee of all money that shall have been delivered by the Company
to the Paying Agent, the Paying Agent shall have no further liability for the
money. If the Company, a Subsidiary or any other obligor upon the Notes 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.

                  Section 2.5. 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 Holders and shall otherwise comply with TIA Section 312(a). If the
Trustee is not the Registrar, the Company (or any other obligor upon the Notes)
shall furnish to the Trustee at least seven Business Days before each interest
payment date (and in all events at intervals of not more than six months) 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 Holders, and the Company shall otherwise comply with TIA Section 312(a).

                  Section 2.6. Transfer and Exchange.

                  The Notes will be issued in fully registered form and will be
transferable only upon the surrender of the Notes being transferred for
registration of transfer. Where Notes are

                                      -26-
<PAGE>

presented to the Registrar or a co-registrar with a request to register,
transfer or exchange them for an equal principal amount of Notes of other
denominations, the Registrar shall register the transfer or make the exchange if
its requirements for such transactions are met; provided that any Note presented
or surrendered for registration of transfer or exchange shall be duly endorsed
or accompanied by a written instruction of transfer in form satisfactory to the
Registrar and the Trustee duly executed by the Holder thereof or his attorney
duly authorized in writing. To permit registrations of transfer and exchanges in
compliance with this Indenture, the Company shall issue and the Trustee shall
authenticate Notes at the Registrar's request.

                  The Company shall not be required (i) to issue, to register
the transfer of or to exchange Notes during a period beginning at the opening of
business on a Business Day 15 days before the day of any selection of Notes for
redemption under Section 3.2 hereof and ending at the close of business on the
day of selection, (ii) to register the transfer of or exchange of a Note so
selected for redemption in whole or in part, except the unredeemed portion of
any Note being redeemed in part or (iii) to register the transfer or exchange of
a Note between the record date and the next succeeding interest payment date.

                  No service charge shall be made for any registration of
transfer or exchange (except as otherwise expressly permitted herein), but the
Company may require payment of a sum sufficient to cover any tax, assessment or
other governmental charge payable in connection therewith (other than such
transfer tax or similar governmental charge payable upon exchanges pursuant to
Section 2.10, 3.6 or 9.5 hereof).

                  Prior to the registration of any transfer by a Holder as
provided herein, the Company, the Trustee and any Agent of the Company shall
treat the Person in whose name the Note is registered on the register maintained
by the Trustee as the owner thereof for all purposes whether or not the Note
shall be overdue, and none of the Company, the Trustee nor any such Agent shall
be affected by notice to the contrary. Any consent, waiver or actions of a
Holder shall be binding upon any subsequent Holders of such Note or a Note
received upon transfer.

                  Any Holder of a beneficial interest in a Global Note shall, by
acceptance of such beneficial interest in a Global Note, agree that transfers of
beneficial interests in such Global Note may be effected only through a
book-entry system maintained by the Depository (or its agent), and that
ownership of a beneficial interest in a Global Note shall be required to be
reflected in a book entry.

                  Section 2.7. Replacement Notes.

                  If any mutilated Note is surrendered to the Trustee, or the
Company and the Trustee receive evidence to their satisfaction of the
destruction, loss or theft of any Note, the Company shall issue and the Trustee,
upon the written order of the Company signed by two Officers, shall authenticate
a replacement Note if the Trustee's requirements for replacement of Notes 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 or any authenticating
agent from any loss which any of them may suffer if a Note is replaced. The
Company may charge for its expenses in replacing a Note.

                                      -27-
<PAGE>

                  Every replacement Note is an additional obligation of the
Company and entitled to the benefit of this Indenture.

                  Section 2.8. Outstanding Notes.

                  The Notes outstanding at any time are all the Notes
authenticated by the Trustee except for those cancelled by it, those delivered
to it for cancellation and those described in this Section 2.8 as not
outstanding.

                  If a Note is replaced pursuant to Section 2.7 hereof (other
than a mutilated Note surrendered for replacement), it ceases to be outstanding
unless the Trustee receives proof satisfactory to it that the replaced Note is
held by a bona fide purchaser. A mutilated Note ceases to be outstanding upon
surrender of such Note and replacement thereof pursuant to Section 2.7.

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

                  A Note does not cease to be outstanding because the Company or
an Affiliate holds the Note, except as otherwise provided in Section 2.9 hereof.

                  Section 2.9. 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 a Subsidiary thereof 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 which a Responsible Officer of the Trustee actually knows are so owned
shall be so disregarded.

                  Section 2.10. Temporary Notes.

                  Until definitive Notes are ready for delivery, the Company may
prepare and the Trustee shall authenticate temporary Notes upon receipt of a
written order of the Company in the form of an Officers' Certificate. The
Officers' Certificate shall specify the amount of temporary Notes to be
authenticated and the date on which the temporary Notes are to be authenticated.

                  Temporary Notes shall be substantially in the form of
definitive Notes but may have variations that the Company and the Trustee
consider appropriate for temporary Notes. Without unreasonable delay, the
Company shall prepare and the Trustee shall authenticate upon receipt of a
written order of the Company in the form of an Officers' Certificate pursuant to
Section 2.2 definitive Notes in exchange for temporary Notes.

                                      -28-
<PAGE>

                  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 transfer, exchange or payment. The Trustee shall
cancel and dispose of all Notes surrendered for transfer, exchange, payment,
replacement or cancellation. Subject to Section 2.7, the Company may not issue
new Notes to replace Notes that it has paid or that have been delivered to the
Trustee for cancellation. All cancelled Notes held by the Trustee shall be
disposed of by the Trustee in its customary manner.

                  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. The Company shall, with the consent of the Trustee, fix each such
special record date and payment date. At least 15 days before the special record
date, the Company (or the Trustee, in the name of and at the expense of the
Company) shall mail to Holders a notice that states the special record date, the

                  Section 2.13. Persons Deemed Owners.

                  Prior to due presentment of a Note for registration of
transfer and subject to Section 2.12, the Company, the Trustee, any Paying
Agent, any co-registrar and any Registrar may deem and treat the person in whose
name any Note shall be registered upon the register of Notes kept by the
Registrar as the absolute owner of such Note (whether or not such Note shall be
overdue and notwithstanding any notation of the ownership or other writing
thereon made by anyone other than the Company, any co-registrar and any
Registrar) for the purpose of receiving payments of principal of or interest on
such Note and for all other purposes; and none of the Company, the Trustee, any
Paying Agent, any co-registrar or any Registrar shall be affected by any notice
to the contrary.

                  Section 2.14. CUSIP Numbers.

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

                  Section 2.15. Book-Entry Provisions for Global Notes.

                  (a)      The Global Notes initially shall (i) be registered in

forth in Exhibit C.

                  Members of, or participants in, the Depository
("Participants") shall have no rights under this Indenture with respect to any
Global Note held on their behalf by the Depository, or the Trustee as its
custodian, or under the Global Note, and the Depository may be treated by the
Company, the Trustee and any agent of the Company or the Trustee as the absolute
owner of the Global Note for all purposes whatsoever. Notwithstanding the
foregoing, nothing herein shall prevent the Company, the Trustee or any agent of
the Company or the Trustee from giving effect to any written certification,
proxy or other authorization furnished by the Depository or impair, as between
the Depository and Participants, the operation of customary practices governing
the exercise of the rights of a Holder of any Note.

                  (b)      Transfers of Global Notes shall be limited to
transfers in whole, but not in part, to the Depository, its successors or their
respective nominees. Interests of beneficial owners in the Global Notes may be
transferred or exchanged for Physical Notes in accordance with the rules and
procedures of the Depository and the provisions of Section 2.16; provided,
however, that Physical Notes shall be transferred to all beneficial owners in
exchange for their beneficial interests in Global Notes if (i) the Depository
notifies the Company that it is unwilling or unable to continue as Depository
for the Global Notes and a successor Depository is not appointed by the Company
within 90 days of such notice, (ii) the Depository ceases to be registered as a
clearing agency under the Exchange Act and a successor depository is not
appointed within 90 days, (iii) the Company, at its option, notifies the Trustee
that it elects to cause the issuance of Physical Notes, or (iv) an Event of
Default has occurred and is continuing and the Registrar has received a request
from the Depository to issue Physical Notes.

                  (c)      In connection with the transfer of Global Notes as an
entirety to beneficial owners pursuant to paragraph (b) of this Section 2.15,
the Global Notes shall be deemed to be surrendered to the Trustee for
cancellation, and the Company shall execute, and the Trustee shall upon written
instructions from the Company authenticate and deliver, to each beneficial owner
identified by the Depository in exchange for its beneficial interest in the
Global Notes, an equal aggregate principal amount of Physical Notes of
authorized denominations.

                  (d)      Any Physical Note constituting a Restricted Security
delivered in exchange for an interest in a Global Note pursuant to paragraph (c)
of this Section 2.15 shall, except as otherwise provided by Section 2.16, bear
the Private Placement Legend.

                  (e)      The Holder of any Global Note may grant proxies and
otherwise authorize any Person, including Participants and Persons that may hold
interests through Participants, to take any action which a Holder is entitled to
take under this Indenture or the Notes.

interest in any Note (including any transfers between or among Participants or
beneficial owners of interest in any Global Note) other than to require delivery

required by, and to do so if and when expressly required by the terms of, this

this Indenture which shall have identical terms as the Notes issued on the Issue
Date, other than with respect to the date of issuance, issue price and amount of
interest payable on the first payment date applicable thereto (and, if such
Additional Notes shall be issued in the form of Unrestricted Notes or Exchange

                  The Company shall give each notice to the Trustee provided for
in this Section 3.1 at least 60 days before the Redemption Date unless the
Trustee consents to a shorter period. Such notice shall be accompanied by an
Officers' Certificate and an Opinion of Counsel from the Company to the effect
that such redemption will comply with the conditions herein. If fewer than all
the Notes are to be redeemed, the record date relating to such redemption shall
be selected by the Company and given to the Trustee, which record date shall be
not less than 15 days after the date of notice to the Trustee.

                  Any such notice may be cancelled prior to notice being mailed

                  Section 3.2. Selection of Notes To Be Redeemed.

                  If fewer than all the Notes are to be redeemed, the Trustee
shall select the Notes to be redeemed pro rata or on as nearly a pro rata basis
as possible (subject to Depository's procedures), if any, and that the Trustee
in its sole discretion considers fair and appropriate and in accordance with
methods generally used at the time of selection by fiduciaries in similar
circumstances. The Trustee shall make the selection from outstanding Notes not
previously called for redemption. The Trustee may select for redemption portions
of the principal of Notes that have denominations larger than $1,000. Notes and
portions of them the Trustee selects shall be in amounts of $1,000 or a whole
multiple of $1,000. Provisions of this Indenture that apply to Notes called for
redemption also apply to portions of Notes called for redemption. The Trustee
shall notify the Company promptly of the Notes or portions of Notes to be
redeemed.

                  Section 3.3. Notice of Redemption.

                  At least 30 days but not more than 60 days before a Redemption
Date, the Company shall mail a notice of redemption by first-class mail to each
Holder of Notes to be redeemed at its registered address.

                  The notice shall identify (including the CUSIP number, if any)
the Notes to be redeemed and shall state:

                  (1)      the Redemption Date;

                  (2)      the Redemption Price and accrued interest;

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

                  (4)      that Notes called for redemption must be surrendered
         to the Paying Agent to collect the Redemption Price;

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

                  (6)      that, unless the Company defaults in making such
         redemption payment interest on Notes (or portion thereof) called for
         redemption ceases to accrue on and after the Redemption Date; and

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

                  At the Company's request, the Trustee shall give the notice of
redemption in the Company's name and at the Company's expense. In such event,
the Company shall provide the Trustee with the information required by this
Section 3.3.

                  Once notice of redemption is mailed, Notes called for
redemption become due and payable on the Redemption Date and at the Redemption
Price stated in the notice. Upon surrender to the Paying Agent, such Notes shall
be paid at the Redemption Price stated in the notice, plus accrued interest to
the Redemption Date. Failure to give notice or any defect in the notice to any
Holder shall not affect the validity of the notice to any other Holder.

                  Section 3.5. Deposit of Redemption Price.

                  Prior to the Redemption Date, the Company shall deposit with
the Paying Agent (or, if the Company or any of its Subsidiaries is the Paying
Agent, shall segregate and hold in trust) money sufficient to pay the Redemption
Price of and accrued interest on all Notes to be redeemed on that date, other
than Notes or portions of Notes called for redemption which have been delivered
by the Company to the Trustee for cancellation.

                  Upon surrender and cancellation of a Note that is redeemed in
part, the Company shall execute and the Trustee shall authenticate for the
Holder at the expense of the Company a new Note equal in principal amount to the
unredeemed portion of the Note surrendered.

                  (a) Except as otherwise provided in this Section 3.7, the
Company may not redeem any of the Notes prior to March 15, 2009. At any time on
or after March 15, 2009, the Company may, at its option, redeem outstanding
Notes, in whole or in part, at a Redemption Price equal to a percentage of the
principal amount thereof, as set forth in the immediately succeeding paragraph,
plus all accrued and unpaid interest thereon to the Redemption Date (subject to

due on the relevant interest payment date).

                  The Redemption Price as a percentage of principal amount shall
be as follows, if the Notes are redeemed during the 12-month period commencing
on or after March 15 of the years set forth below:

         under this Indenture remains outstanding immediately after any such
         redemption; and

                  (2)      the Company makes such redemption not more than 90
         days after the consummation of any such Equity Offering.

Qualified Capital Stock of the Company to any Person.

                  No Notes of a principal amount of $1,000 or less shall be
redeemed in part. If a partial redemption is made pursuant to the foregoing
provision, the Trustee will select the Notes only on a pro rata basis or on as
nearly a pro rata basis as is practicable (subject to the Depository's
procedures).

                  Any redemption pursuant to this Section 3.7 shall be made

any, and interest on the Notes on the dates and in the manner provided in the

Until otherwise designated by the Company in a written notice to the Trustee,
such office or agency in The City of New York shall be the principal corporate

                  Section 4.3. Insurance Matters.

                  The Company shall provide or cause to be provided, for itself
and each of its Restricted Subsidiaries, insurance against loss or damage of the
kinds that, in the reasonable, good faith opinion of the Company, are adequate
and appropriate for the conduct of the business of the Company and its
Restricted Subsidiaries in a prudent manner, with reputable insurers or with the
government of the United States of America or an agency or instrumentality
thereof, in such amounts, with such deductibles, and by such methods as shall be
customary, in the reasonable, good faith opinion of the Company, for
corporations similarly situated in the industry, unless the failure to provide
such insurance (together with all other such failures) would not have a material
adverse effect on the financial condition or results of operations of the
Company and its Restricted Subsidiaries, taken as a whole.

                  Section 4.4. SEC Reports.

                  Notwithstanding that the Company may not be required to remain
subject to the reporting requirements of Section 13 or 15(d) of the Exchange
Act, the Company shall file with the SEC and provide the Trustee and Holders of
the Notes:

                  (1)      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 Results of Operations" that describes the financial
         condition and results of operations of the Company and its consolidated
         Subsidiaries (showing in reasonable detail, 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," 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, if any) and, with respect to the annual information only,
         a report thereon by the Company's certified independent accountants;
         and

                                      -38-
<PAGE>

                  (2)      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, in each case within the time periods specified in the
         SEC's rules and regulations.

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

                  In addition, following the consummation of the exchange offer
contemplated by the Registration Rights Agreement, whether or not required by
the rules and regulations of the SEC, the Company shall file a copy of all such
information and reports 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 information available to securities analysts
and prospective investors upon request. In addition, the Company has agreed
that, for so long as any Notes remain outstanding, it will furnish to the
Holders and to securities analysts and prospective investors, upon their
request, the information required to be delivered pursuant to Rule 144(d)(4)
under the Securities Act.

                  Section 4.5. Compliance Certificate.

                  The Company shall deliver to the Trustee within 120 days after
the end of each fiscal year of the Company an Officers' Certificate stating that
in the course of the performance by the signers of their duties as Officers of
the Company they would normally have knowledge of any Default by the Company and
whether or not the signers know of any Default that occurred during such period.
If they do, the certificate shall describe the Default, its status and what
action the Company is taking or proposes to take with respect thereto. The
Company also shall comply with TIA Section 314(a)(4).

                  Section 4.6. Corporate Existence.

                  Subject to Article 5, the Company will do or cause to be done
all things necessary to preserve and keep in full force and effect its corporate
existence, material rights (charter and statutory) and franchises; provided,
however, that the Company shall not be required to preserve any such material
right or franchise if the preservation thereof is no longer desirable in the
conduct of the business of the Company or the loss thereof is not materially
adverse to the Holders of the Notes.

                  Section 4.7. Payment of Taxes and Other Claims.

                  The Company will pay or discharge or cause to be paid or
discharged, before any penalty accrues thereon, (1) all material taxes,
assessments and governmental charges levied or imposed upon the Company or any
Subsidiary or upon the income, profits or property of the Company or any
Subsidiary, and (2) all material lawful claims for labor, materials and supplies
which, if unpaid, might by law become a Lien upon the property of the Company or
any Subsidiary; provided, however, that the Company shall not be required to pay
or discharge or cause to

                                      -39-

be paid or discharged any such tax, assessment, charge or claim whose amount,
applicability or validity is being contested in good faith by appropriate
proceedings.

                  Section 4.8. Appointments To Fill Vacancies in Trustee's
Office.

                  The Company, whenever necessary to avoid or fill a vacancy in
the office of the Trustee, will appoint, in the manner provided in Section 7.8,
a Trustee, so that there shall at all times be a Trustee hereunder.

                  Section 4.9. Limitation on Indebtedness.

                  (a)      The Company shall not, and shall not permit any
Restricted Subsidiary to, Incur any Indebtedness (other than Permitted
Indebtedness) except that the Company and any Restricted Subsidiary that is a
Guarantor may Incur Indebtedness if, after giving effect thereto (i) the
Consolidated Coverage Ratio at the date of such Incurrence exceeds 2.25 to 1.0
(this clause (i), the "Coverage Ratio Exception"); 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.

                  (b)      Notwithstanding the foregoing paragraph (a), the

Indebtedness (collectively, "Permitted Indebtedness"):

                  (1)      Indebtedness Incurred pursuant to the Credit
          Agreement so long as the aggregate principal amount of such
          Indebtedness outstanding at any time shall not exceed $350.0 million;

                  (2)      Subordinated Indebtedness owed to and held by a
         Wholly Owned Subsidiary; provided, however, that any subsequent
         issuance or transfer of any Capital Stock or any other event which
         results in any such Wholly Owned Subsidiary ceasing to be a Wholly
         Owned Subsidiary or any subsequent transfer of such Subordinated
         Indebtedness (other than to another Wholly Owned Subsidiary) shall be
         deemed, in each case, to constitute the Incurrence of such Subordinated
         Indebtedness by the Company;

                  (3)      Indebtedness pursuant to the Notes and the Subsidiary
         Guarantees issued on the Issue Date and any Exchange Notes and

         outstanding does not exceed $30.0 million;

                  (8)      Indebtedness or Capital Stock issued to and held by
         the Company or (x) a Wholly Owned Subsidiary or (y) a Restricted
         Subsidiary that is not a Wholly Owned Subsidiary; provided that any
         Indebtedness held by a Restricted Subsidiary that is not a Wholly Owned
         Subsidiary that is Incurred pursuant to this clause (b)(8)(y) shall be
         Incurred solely for cash management purposes in the ordinary course of
         business; provided further, however, that any subsequent issuance or
         transfer of any Capital Stock or any other event which results in any
         such Wholly Owned Subsidiary ceasing to be a Wholly Owned Subsidiary or
         any subsequent transfer of such Indebtedness or Capital Stock (other
         than to the Company or a Wholly Owned Subsidiary) shall be deemed, in
         each case, to constitute the issuance of such Indebtedness or Capital
         Stock by the issuer thereof;

                  (9)      Indebtedness or Capital Stock of a Subsidiary
         Incurred and outstanding on or prior to the date on which such

         Capital Stock Incurred in connection with, or to provide all or any
         portion of the funds or credit support utilized to consummate, the
         transaction or series of related transactions pursuant to which such

         originally Incurred such Indebtedness or by the Company or any
         Guarantor;

                  (10)     Indebtedness Incurred by any Restricted Subsidiary
         that is a Foreign Subsidiary; provided, however, that any such
         Indebtedness Incurred by such Restricted Subsidiary shall not exceed
         $15.0 million in the aggregate, taken together with all other
         Indebtedness of Foreign Subsidiaries Incurred pursuant to this Section
         4.9(b)(10) then outstanding;

         Subsidiary; provided further, that after giving effect to the
         Incurrence of such Indebtedness, the Company would be able to Incur an
         additional $1.00 of Indebtedness pursuant to Section 4.9(a), and any
         refinancings thereof by such Restricted Subsidiary provided that the
         principal amount thereof is not increased;

         accordance with GAAP;

                  (13)     Indebtedness of the Company or any Restricted
         Subsidiary consisting of guarantees of Indebtedness Incurred by
         officers and employees of the Company or any Restricted Subsidiary;
         provided that the aggregate amount of such guaranteed Indebtedness,

         time exceed $2.5 million in the aggregate;

                  (14)     Indebtedness of the Company or any Restricted
         Subsidiary arising from the honoring of a check, draft or similar

         such disposition of assets;

                  (16)     Indebtedness under commodity agreements such as

Guarantor to, directly or indirectly, Incur any Indebtedness which by its terms
(or by the terms of any agreement governing such Indebtedness) is expressly
subordinated in right of payment to any other Indebtedness of the Company or
such Guarantor, as the case may be, unless such Indebtedness is also by its
terms (or by the terms of any agreement governing such Indebtedness) made
expressly subordinate to the Notes or the applicable Subsidiary Guarantee, as
the case may be, to the same extent and in the same manner as such Indebtedness
is subordinated to other Indebtedness of the Company or such Guarantor, as the
case may be.

Section 4.9, in the event that an item of Indebtedness meets the criteria of
more than one of the categories in clauses (1) - (17) of Section 4.9(b) or is
entitled to be Incurred pursuant to the Coverage Ratio Exception, the Company
shall, in its sole discretion, classify or reclassify such item of Indebtedness
in one or more of the types of Indebtedness described, except that Indebtedness
Incurred under the Credit Agreement or Leasing Indebtedness on the Issue Date
shall be deemed to have been Incurred under clause (b)(1) or clause (b)(12) of

                  (a)      The Company may, on or after the Issue Date,
designate any Subsidiary of the Company (other than a Subsidiary of the Company
which owns Capital Stock of a Restricted Subsidiary or is a Guarantor) as an
"Unrestricted Subsidiary" under this Indenture (a "Designation") only if:

                  (1)      no Default or Event of Default shall have occurred
         and be continuing at the time of or after giving effect to such
         Designation;

                  (2)      the Company would be permitted under this Indenture
         to make an Investment at the time of Designation (assuming the
         effectiveness of such Designation) in an amount (the "Designation
         Amount") equal to the sum of (A) the Fair Market Value of the Capital
         Stock of such Subsidiary owned by the Company and/or any of the
         Restricted Subsidiaries on such date and (B) the aggregate amount of

         additional Indebtedness (other than Permitted Indebtedness) pursuant to
         Section 4.9 at the time of Designation (assuming the effectiveness of
         such Designation).

                  In the event of any such Designation, the Company shall be
deemed to have made an Investment constituting a Restricted Payment in the
Designation Amount pursuant to Section 4.11 for all purposes of this Indenture.

                  (b)      The Company shall not, and shall not permit any
Restricted Subsidiary to, at any time:

                  (x)      provide direct or indirect credit support for or a
         guarantee of any Indebtedness of any Unrestricted Subsidiary (including
         any undertaking agreement or instrument evidencing such Indebtedness);

                  (y)      be directly or indirectly liable for any Indebtedness
         of any Unrestricted Subsidiary; or

                  (z)      be directly or indirectly liable for any Indebtedness
         which provides that the holder thereof may (upon notice, lapse of time
         or both) declare a default thereon or cause the payment thereof to be
         accelerated or payable prior to its final scheduled maturity upon the
         occurrence of a default with respect to any Indebtedness of any
         Unrestricted Subsidiary (including any right to take enforcement action
         against such Unrestricted Subsidiary), except, in the case of clause
         (x) or (y), to the extent permitted under Section 4.11.

                  (c)      The Company may revoke any Designation of a
Subsidiary as an Unrestricted Subsidiary ("Revocation"), whereupon such
Subsidiary shall then constitute a Restricted Subsidiary, if

                                      -43-
<PAGE>

                  (1)      no Default or Event of Default shall have occurred
         and be continuing at the time and after giving effect to such
         Revocation; and

                  (2)      all Liens and Indebtedness of such Unrestricted
         Subsidiaries outstanding immediately following such Revocation would,
         if Incurred at such time, have been permitted to be Incurred for all
         purposes of this Indenture.

                  All Designations and Revocations must be evidenced by an
officers' certificate of the Company delivered to the trustee certifying
compliance with the foregoing provisions.

Restricted Subsidiary, directly or indirectly, to make a Restricted Payment if
at the time the Company or such Restricted Subsidiary makes such Restricted
Payment:

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

         of Indebtedness pursuant to Section 4.9(a); or

                  (3)      the aggregate amount of all Restricted Payments
         (including such proposed Restricted Payment) made subsequent to the
         Issue Date would exceed the sum of

                           (i)      50% of the aggregate cumulative amount of
                           Consolidated Net Income of the Company earned during
                           the period subsequent to March 31, 2004 and ending
                           prior to the date of such Restricted Payment (such
                           date, the "Reference Date") (or, in case such
                           Consolidated Net Income shall be a deficit, minus
                           100% of such deficit);

                           (ii)     100% of the aggregate Net Cash Proceeds and

                           acquire Qualified Capital Stock of the Company (but
                           excluding any debt security that is convertible into,
                           or exchangeable for, Qualified Capital Stock); and

         than 60 days following the applicable Asset Sale Offer Trigger Date,
         from all Holders and from all holders of other Indebtedness of the

         payment to the Notes and the terms of which require an offer to
         purchase such other Indebtedness with the proceeds from the Asset
         Disposition, on a pro rata basis, that amount of Notes and such other
         Indebtedness equal to the Asset Sale Offer Amount at a price equal to
         100% of the principal amount of such Notes or such other Indebtedness
         (or the accreted value of such other Indebtedness, if such other
         Indebtedness is issued at a discount), to be purchased, plus accrued
         and unpaid interest, if any, thereon to the date of purchase.

or regulations thereunder in connection with the repurchase of Notes pursuant to
this Indenture. To the extent that the provisions of any applicable laws or
regulations conflict with the provisions of this Section 4.13, the Company shall
comply with the applicable laws and regulations and shall not be deemed to have
breached its obligations under the indenture by virtue of any conflict.

Restricted Subsidiary to, enter into or permit to exist any transaction or
series of transactions (including the purchase, sale, lease or exchange of any
property, employee compensation arrangements or the rendering of any service)

thereof are no less favorable to the Company or such Restricted Subsidiary than
those which could be obtained at the time of such transaction in arm's-length
dealings with a Person who is not such an Affiliate.

                  In addition, the Company shall not, and shall not permit any
Restricted Subsidiary to, enter into any Affiliate Transaction unless:

         effect that such Affiliate Transaction is fair to the Company or such
         Restricted Subsidiary, as the case may be, from a financial point of
         view.

                  (b)      The provisions of the foregoing Section 4.14(a) shall
         not prohibit:

                  (v)      any Affiliate Transaction between the Company and a
         Restricted Subsidiary or between Restricted Subsidiaries.

                  (a)      Upon the occurrence of a Change of Control, each
Holder shall have the right to require that the Company repurchase such Holder's
Notes (a "Change of Control Offer") at a purchase price in cash equal to 101% of
the principal amount thereof plus accrued and unpaid interest, if any, to the
date of purchase (subject to the right of holders of record on the relevant
record date to receive interest on the relevant interest payment date), in
accordance with Section 4.15(b); provided, however, that notwithstanding the
occurrence of a Change of Control, the Company will not be obligated to purchase

         purchase (subject to the right of holders of record on the relevant
         record date to receive interest on the relevant interest payment date);

                  The Notes shall be guaranteed by each existing or future
Restricted Subsidiary of the Company that is a guarantor of or otherwise an
obligor with respect to any other Indebtedness of the Company. If the Company or

occurred and is continuing under this Indenture (the "Suspension Period"),
Sections 4.9, 4.10, 4.11, 4.12, 4.13 and 4.14 will not apply (collectively, the
"Suspended Covenants"). Upon the suspension of the Suspended Covenants, the
amount of Net Cash Proceeds for purposes of Section 4.13 shall be set at zero.

                  (b)      In the event that the Company and its Restricted
Subsidiaries are not subject to the Suspended Covenants for any period of time
as a result of Section 4.19(a) and either Rating Agency subsequently withdraws
its rating or downgrades its rating of the Notes below Investment Grade, or a
Default or Event of Default occurs and is continuing, then the Company and its
Restricted Subsidiaries shall thereafter again be subject to the Suspended
Covenants (such date, the "Reversion Date"). On the Reversion Date, all
Indebtedness incurred during the Suspension Period prior to such Reversion Date
shall be deemed to have been outstanding on the Issue Date and classified as
permitted under Section 4.9(b)(4). For purposes of calculating the amount
available to be made as Restricted Payments under Section 4.11(a)(3),
calculations under such Section 4.11(a)(3) will be made with reference to the
Issue Date as set forth in that Section. Accordingly, (x) Restricted Payments
made during the Suspension Period will reduce the amount available to be made as
Restricted Payments under Section 4.11(a) and (y) the items specified in
Sections 4.11(a)(3)(i) and (a)(3)(ii) will increase the amount available to be
made as Restricted Payments under Section 4.11(a)(3).

                  The results of actions taken by the Company and the Restricted
Subsidiaries during the period in which the Notes are rated Investment Grade,
and did not otherwise violate this

                                      -51-

Indenture at the time such actions were taken, shall be permitted to remain in
place after any date on which the Notes are no longer rated Investment Grade
without causing a Default or Event of Default.

                  Section 5.1.      Merger and Consolidation.

                  Neither the Company nor any Guarantor shall consolidate with
or merge with or into, or convey, transfer or lease all or substantially all its
assets to, any Person, unless:

                  (i)      the resulting, surviving or transferee Person (the
         "Successor Company") shall be a Person organized and existing under the
         laws of the United States of America, any state thereof or the District
         of Columbia and the Successor Company (if not the Company or such
         Guarantor) shall expressly assume, by an indenture supplemental to this
         Indenture, executed and delivered to the Trustee, in form reasonably
         satisfactory to the Trustee, all the obligations of the Company under
         the Notes and this Indenture or the Guarantor under the Subsidiary
         Guarantee and this Indenture, as applicable;

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

                  (iii)    immediately after giving effect to such transaction,
         the Company would be able to Incur at least an additional $1.00 of
         Indebtedness pursuant to the Coverage Ratio Exception.

                  The Company shall deliver to the Trustee prior to the
consummation of the proposed transaction an Officers' Certificate to the
foregoing effect and an Opinion of Counsel stating that the proposed transaction
and such supplemental indenture comply with this Indenture.

                  Section 5.2.      Successor Corporation Substituted.

                  The Successor Company shall be the successor to the Company or
Guarantor, as the case may be, and shall succeed to, and be substituted for, and
may exercise every right and power of, the Company under this Indenture, but the
predecessor Company in the case of a conveyance, transfer or lease shall not be
released from the obligation to pay the principal of and interest on the Notes.

                              DEFAULTS AND REMEDIES

                  Section 6.1.      Events of Default.

                  An "Event of Default" is defined herein as:

                  (i)      a default in the payment of interest on the Notes
         when due, continued for 30 days;

                  (ii)     a default in the payment of principal of any Note
         when due at its Stated Maturity, upon redemption, upon required
         repurchase, upon declaration or otherwise;

                  (iii)    the failure by the Company to comply for 30 days
         after notice with its obligations under Section 4.4, 4.9, 4.10. 4.11,
         4.12, 4.13, 4.14, 4.16 or 4.17 and its other agreements contained in
         this Indenture (except in the case of a default with respect to
         Sections 4.15 and 5.1, which will constitute Events of Default with
         notice but without passage of time);

                  (iv)     the failure to pay at the final stated maturity
         (after giving effect to any applicable grace periods) Indebtedness
         (other than Non-Recourse Leasing Indebtedness) of the Company or any
         Restricted Subsidiary, or the acceleration of such Indebtedness (other
         than Non-Recourse Leasing Indebtedness) of the Company or any
         Restricted Subsidiary by the holders thereof because of a default, if
         the aggregate principal amount of such Indebtedness exceeds $10.0
         million (or its foreign currency equivalent);

                  (v)      the Company or any Significant Subsidiary pursuant to
         or within the meaning of any Bankruptcy Law:

                           (A)      commences a voluntary case;

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

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

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

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

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

                           (A)      is for relief against the Company or any
                  Restricted Subsidiary in an involuntary case;

                                      -53-

<PAGE>

                           (B)      appoints a Custodian of the Company or any
                  Restricted Subsidiary or for any substantial part of its
                  property; or

                           (C)      orders the winding up or liquidation of the
                  Company or any Restricted Subsidiary;

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

                  (vii)    any judgment or decree for the payment of money in
         excess of $10.0 million (or its foreign currency equivalent) (to the
         extent not covered by insurance) is rendered against the Company or any
         Restricted Subsidiary and is not discharged, paid or stayed for a
         period of 60 consecutive days after such judgment or judgments become
         final and non-appealable; or

                  (viii)   the Subsidiary Guarantee of any Significant
         Subsidiary ceases to be in full force and effect (except as
         contemplated by the terms of the Subsidiary Guarantee under this
         Indenture and this Indenture) or is declared null and void in a
         judicial proceeding or any Guarantor denies or disaffirms its
         obligations under this Indenture or its Subsidiary Guarantee under this
         Indenture.

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

                  The term "Custodian" means any receiver, trustee, assignee,
liquidator, custodian or similar official under any Bankruptcy Law.

                  A Default under clause (iii) of this Section 6.1 is not an
Event of Default until the Trustee or the Holders of at least 25% in principal
amount of the Notes notify the Company of the Default, which notice shall
specify that it is a "Notice of Default".

                  Section 6.2.      Acceleration.

                  If any Event of Default (other than an Event of Default
specified in Section 6.1(v) or (vi) with respect to the Company) occurs and is
continuing, the Trustee by notice to the Company or the Holders of at least 25%
in principal amount of the Notes by written notice to the Company (and the
Trustee, if such notice is given by such Holders), may declare the principal of
and accrued and unpaid interest, if any, on all the Notes to be due and payable
immediately, which notice shall specify the Events of Default and that it is a
"Notice of Acceleration". Upon such a declaration, such principal and interest
shall be due and payable immediately.

                  If an Event of Default specified in Section 6.1(v) or (vi)
with respect to the Company occurs and is continuing, the principal of and
accrued and unpaid interest, if any, on all the

                                      -54-

<PAGE>

Notes shall ipso facto become and be immediately due and payable without any
declaration or other act on the part of the Trustee or any Holders.

                  The Holders of a majority in principal amount of the Notes by
notice to the Company and the Trustee may, on behalf of all of the Holders of
all of the Notes, rescind and cancel an acceleration and its consequences:

                  (1)      if the rescission would not conflict with any
judgment or decrees

                  (2)      if all existing Events of Default have been cured or
waived except nonpayment of principal or interest that has become due solely
because of acceleration;

                  (3)      to the extent that the payment of such interest is
lawful, interest on overdue installments of interest and overdue principal,
which has become due otherwise than by such declaration of acceleration, has
been paid;

                  (4)      if the Company has paid the Trustee its reasonable
compensation and reimbursed the Trustee for its expenses, disbursement and
advances; and

                  (5)      in the event of the cure or waiver of an Event of
Default of the type described in clause (v) of the description above of Events
of Default, the Trustee shall have received an Officers' Certificate and an
opinion of counsel that such Event of Default has been cured or waived. No such
rescission shall affect any subsequent Default or impair any right consequent
thereto.

                  Section 6.3.      Other Remedies.

                  If an Event of Default occurs and is continuing, the Trustee
may pursue any available remedy to collect the payment of principal of or
interest 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 in exercising any right or remedy
accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. No remedy is
exclusive of any other remedy. All available remedies shall be cumulative.

                  Section 6.4.      Waiver of Past Defaults.

                  The Holders of a majority in principal amount of the Notes by
notice to the Trustee may waive an existing Default and its consequences except
(i) a Default in the payment of the principal of or interest on a Note or (ii) a
Default in respect of a provision that under Section 9.2 cannot be amended
without the consent of each Holder affected. When a Default is waived, it is
deemed cured, but no such waiver shall extend to any subsequent or other Default
or impair any consequent right.

                  Section 6.5.      Control by Majority.

                  The Holders of a majority in principal amount of the Notes may
direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee or of exercising any trust or power conferred on the
Trustee. However, the Trustee may refuse to follow any direction that conflicts
with law or this Indenture or, subject to Section 7.1, that the Trustee
determines is unduly prejudicial to the rights of other Holders or would involve
the Trustee in personal liability; provided, however, that the Trustee may take
any other action deemed proper by the Trustee that is not inconsistent with such
direction. Prior to taking any action hereunder, the Trustee shall be entitled
to indemnification satisfactory to it in its sole discretion against all losses
and expenses caused by taking or not taking such action.

                  Section 6.6.      Limitation on Suits.

                  A Holder may not pursue any remedy with respect to this
Indenture or the Notes unless:

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

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

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

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

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

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

                  Section 6.7.      Rights of Holders To Receive Payment.

                  Notwithstanding any other provision of this Indenture, the
right of any Holder to receive payment of principal of and interest on those
Notes held by such Holder, on or after the respective due dates expressed in the
Notes, or to bring suit for the enforcement of any such payment on or after such
respective dates, shall not be impaired or affected without the consent of such
Holder.

                  Section 6.8.      Collection Suit by Trustee.

                  If an Event of Default in payment of interest or principal
specified in Section 6.1(i) or (ii) occurs and is continuing, the Trustee may
recover judgment in its own name and as trustee of an express trust against the
Company for the whole amount of principal and interest

                                      -56-

remaining unpaid (together with interest on such unpaid interest to the extent
lawful) and the amounts provided for in Section 7.7.

                  Section 6.9.      Trustee May File Proofs of Claim.

                  The trustee may file such proofs of claim and other papers or
documents as may be necessary or advisable in order to have the claims of the
Trustee and the Holders allowed in any judicial proceedings relative to the
Company, its creditors or its property and, unless prohibited by law or
applicable regulations, may vote on behalf of the Holders in any election of a
trustee in bankruptcy or other person performing similar functions, and any
Custodian in any such judicial proceeding is hereby authorized by each Holder to
make payments to the Trustee and, in the event that the Trustee shall consent to
the making of such payments directly to the Holders, to pay to the Trustee any
amount due it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and its counsel, and any other amounts due
the Trustee under Section 7.7.

                  Section 6.10.     Priorities.

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

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

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

                  THIRD:  to the Company.

                  The Trustee may fix a record date and payment date for any
payment to Holders pursuant to this Section 6.10. At least 15 days before such
record date, the Trustee shall mail to each Holder and the Company a notice that
states the record date, the payment date and amount to be paid.

                  Section 6.11.     Undertaking for Costs.

                  In any suit for the enforcement of any right or remedy under
this Indenture or in any suit against the Trustee for any action taken or
omitted by it as Trustee, a court in its discretion may require the filing by
any party litigant in the suit of an undertaking to pay the costs of the suit,
and the court in its discretion may assess reasonable costs, including
reasonable attorneys' fees and expenses, 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 pursuant to Section 6.7 or a suit by Holders of more than 10% in
principal amount of the Notes.

                  Section 6.12.     Waiver of Stay or Extension Laws.

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

                                     TRUSTEE

                  Section 7.1.      Duties of Trustee.

                  (1)      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 their
exercise, as a prudent person would exercise or use under the circumstances in
the conduct of his own affairs.

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

                  (a)      The Trustee need perform only those duties that are
         specifically set forth in this Indenture and no others, and no implied
         covenants or obligations shall be read into this Indenture against the
         Trustee.

                  (b)      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, in the case of any such certificates or
         opinions which by any provision hereof are specifically required to be
         furnished to the Trustee, the Trustee shall examine the certificates
         and opinions to determine whether or not they conform to the
         requirements of this Indenture (but need not confirm or investigate the
         accuracy of any mathematical calculations or other facts stated
         therein).

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

                  (a)      This paragraph does not limit the effect of paragraph
         (2) of this Section 7.1.

                  (b)      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.

                                      -58-

<PAGE>

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

                  (4)      Whether or not therein expressly so provided, every
provision of this Indenture that in any way relates to the Trustee is subject to
paragraphs (1), (2), (3) and (5) of this Section 7.1.

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

                  (6)      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 7.2.      Rights of Trustee.

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

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

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

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

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

                  (6)      The Trustee shall not be deemed to have notice of any
Default or Event of Default unless a Responsible Officer of the Trustee has
actual knowledge thereof or unless written notice of any event which is in fact
such a default is received by the Trustee at the Corporate Trust Office of the
Trustee, and such notice references the Notes and this Indenture.

                  (7)      The rights, privileges, protections, immunities and
benefits given to the Trustee, including, without limitation, its right to be
indemnified, are extended to, and shall be enforceable by, the Trustee in each
of its capacities hereunder, and each agent, custodian and other Person employed
to act hereunder.

                  Section 7.3.      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 an
Affiliate with the same rights it would have if it were not Trustee. Any Paying
Agent may do the same with like rights. However, the Trustee is subject to
Sections 7.10 and 7.11.

                  Section 7.4.      Trustee's Disclaimer.

                  The Trustee 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 hereof, 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 other than its certificate of
authentication.

                  Section 7.5.      Notice of Defaults.

                  If a Default occurs and is continuing, the Trustee shall mail
to Holders a notice of the Default, if known to the Trustee, within 90 days
after it occurs. In the absence of notice to the contrary, the Trustee shall be
entitled to assume that such obligations are outstanding. Except in the case of
a Default in payment on any Note (including the failure to make a mandatory
redemption pursuant hereto), 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 not opposed to the interests of Holders.

                  Section 7.6.      Reports by Trustee to Holders.

                  Within 60 days after each May 15, beginning with the May 15
following the date of this Indenture, the Trustee shall mail to Holders a brief
report dated as of such reporting date that complies with TIA Section 313(a), if
such a report is required pursuant to TIA Section 313(a). The Trustee also shall
comply with TIA Section 313(b). The Trustee shall also transmit by mail all
reports as required by TIA Section 313(c).

                  Commencing if and when this Indenture is qualified under the
TIA, a copy of each report at the time of its mailing to Holders shall be filed
with the SEC and each stock exchange on which the Notes are listed. The Company
or any other obligor upon the Notes shall promptly notify the Trustee when the
Notes are listed on any stock exchange or delisted therefrom.

                  Section 7.7.      Compensation and Indemnity.

                  The Company and the Guarantors, jointly and severally, shall
pay to the Trustee from time to time such compensation as shall be agreed in
writing from time to time by the Company and the Trustee 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, jointly and severally, shall reimburse the Trustee upon
request for all reasonable disbursements, advances and expenses incurred by it.
Such expenses shall include the reasonable compensation, disbursements and
expenses of the Trustee's agents and counsel. The obligations of the Company and
the Guarantors under this Section 7.7 to compensate and indemnify the Trustee
and its agents and to reimburse the Trustee for its reasonable expenses shall
survive the termination of the Company's obligations hereunder and the
satisfaction and discharge of this Indenture.

                  The Company and the Guarantors, jointly and severally, shall
indemnify the Trustee, its employees, officers, directors and agents, and any
predecessor trustee against any and all losses, liabilities, damages, claims, or
expenses, including taxes (other than taxes based on the income of the Trustee),
incurred by it arising out of or in connection with the acceptance or
administration of its duties under this Indenture, except as set forth in the
next paragraph. The Trustee shall notify the Company promptly of any claim for
which it may seek indemnity of which a Responsible Officer has received written
notice. 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 need not pay for any
settlement made without its consent, which consent shall not be unreasonably
withheld.

                  The Company need not reimburse any expense or indemnify
against any loss or liability incurred by the Trustee through its own negligence
or willful misconduct.

                  To secure the Company's payment obligations in this Section
7.7, 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 and the resignation or removal of the Trustee.
Compensation, reimbursement and indemnification to the Trustee under this
Section 7.7 is not subordinated to Senior Indebtedness.

                  When the Trustee incurs expenses or renders services after an
Event of Default specified in Section 6.1(vi) or (vii) with respect to the
Company occurs, the expenses and the compensation for the services are intended
to constitute expenses of administration under any Bankruptcy Law.

                  Section 7.8.      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 7.8.

                                      -61-

<PAGE>

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

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

                  (2)      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;

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

                  (4)      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 and any other obligor upon the
Notes shall promptly appoint a successor Trustee.

                  If a successor Trustee does not take office within 10 days
after the retiring Trustee resigns or is removed, the retiring Trustee, the
Company or the Holders 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 who has
been a Holder for at least six months fails to comply with Section 7.10, such
Holder may petition any court of competent jurisdiction for the removal of the
Trustee and the appointment of a successor Trustee.

                  A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Thereupon the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee shall mail a notice of its
succession to Holders. The retiring Trustee shall, upon payment of its charges
hereunder, promptly transfer all property held by it as Trustee to the successor
Trustee, subject to the Lien provided for in Section 7.7. Notwithstanding
replacement of the Trustee pursuant to this Section 7.8, the Company's
obligations under Section 7.7 thereof shall continue for the benefit of the
retiring Trustee.

                  Section 7.9.      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 which shall be
a corporation organized and doing business under the laws of the United States
of America or of any state thereof authorized under such laws to exercise
corporate trustee power, shall be subject to supervision or

                                      -62-

examination by Federal or state authority and shall have a combined capital and
surplus of at least $50,000,000 as set forth in its most recent published annual
report of condition. No obligor upon the Notes or any Affiliate of such obligor
shall serve as trustee upon the Notes.

                  This Indenture shall always have a Trustee who satisfies the
requirements of TIA Section 310(a)(1). The Trustee is subject to TIA Section
310(b) regarding disqualification of a trustee upon acquiring any conflicting
interest.

                  Section 7.11.     Preferential Collection of Claims Against
                                    Company.

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

                                   ARTICLE 8

                    LEGAL DEFEASANCE AND COVENANT DEFEASANCE

                  Section 8.1.      Option To Effect Legal Defeasance or
                                    Covenant Defeasance.

                  The Company may, at the option of its Board of Directors
evidenced by a board resolution, at any time, elect to have either Section 8.2
or 8.3 be applied to all outstanding Notes upon compliance with the conditions
set forth below in this Article 8.

                  Section 8.2.      Legal Defeasance and Discharge.

                  Upon the Company's exercise under Section 8.1 hereof of the
option applicable to this Section 8.2, the Company shall, subject to the
satisfaction of the conditions set forth in Section 8.4, be deemed to have been
discharged from its obligations with respect to all outstanding Notes on the
date the conditions set forth below are satisfied (hereinafter, "Legal
Defeasance"). For this purpose, Legal Defeasance means that the Company shall be
deemed to have paid and discharged the entire Indebtedness represented by the
outstanding Notes, which shall thereafter be deemed to be "outstanding" only for
the purposes of Section 8.5 and the other Sections of this Indenture referred to
in clauses (a) through (d) below, and to have satisfied all of 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:

                  (i)      rights of registration of transfer and exchange and
         the Company's right of redemption;

                  (ii)     substitution of mutilated, defaced, destroyed, lost
         or stolen Notes;

                  (iii)    rights of Holders of the Notes to receive payments of
         principal and interest on the Notes;

                                      -63-

<PAGE>

                  (iv)     the rights, obligations and immunities of the Trustee
         under this Indenture; and

                  (v)      rights of the holders of the Notes as beneficiaries
         of this Indenture with respect to the property so deposited with the
         Trustee payable to all or any of them.

                  Subject to compliance with this Article 8, the Company may
exercise its option under this Section 8.2, notwithstanding the prior exercise
of its option under Section 8.3.

                  Section 8.3.      Covenant Defeasance.

                  Upon the Company's exercise under Section 8.1 of the option
applicable to this Section 8.3, the Company and the Guarantors, if any, shall,
subject to the satisfaction of the conditions set forth in Section 8.4, be
released from their respective obligations under the covenants contained in
Sections 4.4, 4.7, 4.9 through 4.18, inclusive, and Sections 5.1 and 10.1 with
respect to the outstanding Notes on and after the date the conditions set forth
below 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 6.1, but, except as
specified above, the remainder of this Indenture and such Notes shall be
unaffected thereby. In addition, upon the Company's exercise under Section 8.1
of the option applicable to this Section 8.3, subject to the satisfaction of the
conditions set forth in Section 8.4, Sections 6.1(iii), 6.1(iv), 6.1(vii), and
6.1(viii) shall not constitute Events of Default.

                  Section 8.4.      Conditions to Legal or Covenant Defeasance.

                  The following are the conditions precedent to the application
of either Section 8.2 or 8.3 to the outstanding Notes:

                  In order to exercise either Legal Defeasance or Covenant
Defeasance:

                  (1)      the Company must irrevocably deposit with the Trustee
         (or another trustee satisfying the requirements of Section 7.10 who has
         agreed to comply with the provisions of this Article 8 applicable to
         it), in trust, for the benefit of the Holders cash in U.S. dollars,
         U.S. Government Obligations, or a combination thereof, in such amounts
         as will be sufficient, in the opinion of a nationally recognized firm
         of independent public accountants selected by the Company, to pay the
         principal of, premium, if any, and interest on the Notes on the stated
         date for payment thereof or on the applicable redemption date, as the
         case may be;

                                      -64-

<PAGE>

                  (2)      in the case of Legal Defeasance, the Company shall
         have delivered to the Trustee an Opinion of Counsel 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 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;

                  (3)      in the case of Covenant Defeasance, the Company shall
         have delivered to the Trustee an Opinion of Counsel reasonably
         acceptable to the Trustee confirming that the Holders 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;

                  (4)      no Default or Event of Default shall have occurred
         and be continuing on the date of such deposit or insofar as Events of
         Default from bankruptcy or insolvency events are concerned, at any time
         in the period ending on the 91st day after the date of deposit (other
         than a Default or Event of Default resulting from the borrowing of
         funds to be applied to such deposit and the grant of any Lien securing
         such borrowings);

                  (5)      such Legal Defeasance or Covenant Defeasance shall
         not result in a breach or violation of, or constitute a default under
         this Indenture (other than a Default or an Event of Default resulting
         from the borrowing of funds to be applied to such deposit and the grant
         of any Lien securing such borrowings) or any other material agreement
         or instrument to which the Company or any of its Subsidiaries is a
         party or by which the Company or any of its Subsidiaries is bound;

                  (6)      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 or others;

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

                  (8)      the Company shall have delivered to the Trustee an
         Opinion of Counsel to the effect that, assuming no intervening
         bankruptcy of the Company between the date of deposit and the 91st day
         following the date of deposit and that no Holder is an insider of

                                      -65-

<PAGE>

         the Company, after the 91st day following the date of deposit, the
         trust funds will not be subject to the effect of any applicable
         bankruptcy, insolvency, reorganization or similar laws affecting
         creditors' rights generally.

                  Notwithstanding the foregoing, the Opinion of Counsel required
by clause (2) above with respect to a Legal Defeasance need not be delivered if
all Notes not theretofore delivered to the Trustee for cancellation (i) have
become due and payable or (ii) will become due and payable on the Maturity Date
within one year or are to be called for redemption within one year under
arrangements satisfactory to the Trustee for the giving of notice of redemption
by the Trustee in the name, and at the expense, of the Company.

                  Section 8.5.      Deposited Money and U.S. Government
                                    Obligations To Be Held in Trust; Other
                                    Miscellaneous Provisions.

                  Subject to Section 8.6, all money and U.S. Government
Obligations (including the proceeds thereof) deposited with the Trustee (or
other qualifying trustee, collectively for purposes of this Section 8.5 only,
the "Trustee") pursuant to Section 8.4 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 (other than the Company) as the Trustee may determine, to the
Holders of such Notes of all sums due and to become due thereon in respect of
principal or Redemption Price of, and interest on, the Notes, 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 U.S.
Government Obligations deposited pursuant to Section 8.4 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 8 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 U.S. Government Obligations held by it as
provided in Section 8.4 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
8.4(a)), 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 8.6.      Repayment to the Company.

                  Any money deposited with the Trustee or any Paying Agent, or
then held by the Company, in trust for the payment of the principal, Redemption
Price or purchase price of, or interest on any Note and remaining unclaimed for
two years after such amount has become due and payable shall be paid to the
Company on its request or (if then held by the Company) shall be discharged from
such trust; and the Holder of such Note shall thereafter look only to the
Company for payment thereof as a general creditor, 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 re-

                                      -66-

<PAGE>

quired to make any such repayment, at the expense of the Company, if required by
applicable law cause to be published once, in The New York Times and The Wall
Street Journal (national editions), notice that such money remains unclaimed and
that, after a date specified therein, which shall not be less than 30 days after
the date of such notification or publication, any unclaimed balance of such
money then remaining will be repaid to the Company.

                  Section 8.7.      Reinstatement.

                  If the Trustee or Paying Agent is unable to apply any United
States dollars or U.S. Government Obligations in accordance with Section 8.2 or
8.3, 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 obligations of the Company under this Indenture, and the
Notes shall be revived and reinstated as though no deposit had occurred pursuant
to Section 8.2 or 8.3 until such time as the Trustee or Paying Agent is
permitted to apply all such money in accordance with Section 8.2 or 8.3, as the
case may be; provided, however, that, if the Company makes any payment with
respect to 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.

                  Section 8.8.      Termination of Obligations upon Cancellation
                                    of the Notes.

                  This Indenture will be discharged and will cease to be of
further effect (except as set forth below and the Trustee, at the expense of the
Company, shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture when:

                  (1)      either:

                           (a)      all the Notes theretofore authenticated and
                  delivered (except lost, stolen or destroyed Notes which have
                  been replaced or paid and Notes for whose payment money has
                  theretofore been deposited in trust or segregated and held in
                  trust by the Company and thereafter repaid to the Company or
                  discharged from such trust) have been delivered to the Trustee
                  for cancellation;

                           (b)      all Notes not theretofore delivered to the
                  Trustee for cancellation (1) have become due and payable or
                  (2) will become due and payable within one year, or are to be
                  called for redemption within one year, under arrangements
                  satisfactory to the Trustee for the giving of notice of
                  redemption by the Trustee in the name, and at the expense, of
                  the Company, and the Company has irrevocably deposited or
                  caused to be deposited with the Trustee funds in an amount
                  sufficient to pay and discharge the entire Indebtedness on the
                  Notes not theretofore delivered to the Trustee for
                  cancellation, for principal of, premium, if any, and interest
                  on the Notes to the date of deposit together with irrevocable
                  instructions thereof at maturity or redemption, as the case
                  may be;

                  (2)      the Company has paid all other sums payable under
         this Indenture by the Company; and

                  (3)      the Company has delivered to the Trustee an Officers'
         Certificate and an Opinion of Counsel stating that all conditions
         precedent under this Indenture relating to the satisfaction and
         discharge of this Indenture have been complied with.

Indenture the respective obligations of the Company and the Trustee under
Sections 2.2, 2.3, 2.4, 2.5, 2.6, 2.8, 2.14, 3.7, 4.1, 4.2, 6.7, 7.7, 7.8, 8.5,
8.6 and 8.7 and shall survive until the Notes are no longer outstanding, and
thereafter the obligations of the Company and the Trustee under Sections. 7.7,

any of the obligations or duties of the Trustee under this Indenture.

                                   AMENDMENTS

                  Section 9.1.      Without Consent of Holders.

                  The Company and the Trustee may amend or enter into an
indenture or indentures supplemental hereto without the consent of any Holder:

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

                  (2)      to comply with Section 5.2;

                  (3)      to comply with any requirements of the SEC in
         connection with the qualification of this Indenture under the TIA as
         then in effect;

                  (4)      to provide for uncertificated Notes in addition to
         certificated Notes;

                  (5)      to secure the Notes and to make intercreditor
         arrangements with respect to any such Note, unless the incurrence of
         such obligations or the security thereof is prohibited by this
         Indenture;

                  (6)      to evidence or to provide for a replacement Trustee
         under Section 7.8; or

                  (7)      to add to the covenants and agreements of the
         Company, or any obligor with respect to the Notes, for the benefit of
         the Holders of the Notes or to surrender any right or power herein
         conferred on the Company; or

                  (8)      to make any change that does not materially adversely
         affect the rights of any Holder of the Notes.

                  Upon the request of the Company, accompanied by a resolution
of the Board of Directors authorizing the execution of any such amendment or
supplemental indenture, and upon receipt by the Trustee of the documents
described in Section 9.6 hereof, the Trustee shall join with the Company in the
execution of any amendment or supplemental indenture authorized or

                                      -68-

<PAGE>

permitted by the terms of this Indenture and to make any further appropriate
agreements and stipulations which may be therein contained, but the Trustees
shall not be obligated to enter into such amendment or supplemental indenture
which affects its own rights, duties or immunities under this Indenture or
otherwise.

                  Section 9.2.      With Consent of Holders.

                  The Company and the Trustee may amend or enter into an
indenture or indentures supplemental hereto with the written consent of the
Holders of at least a majority in aggregate principal amount of the then
outstanding Notes. The Holders of a majority in principal amount of the Notes
then outstanding may, or the Trustee with the written consent of the Holders of
at least a majority in principal amount of the then outstanding Notes may, waive
compliance in a particular instance by the Company with any provision of this
Indenture or the Notes.

                  Upon the request of the Company, accompanied by a resolution
of the Board of Directors authorizing the execution of any such amendment or
supplemental indenture, and upon the filing with the Trustee of evidence of the
consent of the Holders as aforesaid, and upon receipt by the Trustee of the
documents described in Section 9.6 hereof, the Trustee shall join with the
Company in the execution of such amendment or supplemental indenture unless such
amendment or supplemental indenture 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 amendment or
supplemental indenture.

                  It shall not be necessary for the consent of the Holders under
this Section 9.2 to approve the particular form of any proposed amendment,
supplemental indenture or waiver, but it shall be sufficient if such consent
approves the substance thereof.

                  After an amendment, supplemental indenture or waiver under
Section 9.1 or this Section 9.2 becomes effective, the Company shall mail to the
Holders of each Note affected thereby a copy of such amendment, supplemental
indenture or waiver and a notice briefly describing the amendment, supplemental
indenture 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 amendment, supplemental indenture or waiver.

                  Notwithstanding the first paragraph of this Section 9.2,
without the consent of each Holder affected, an amendment, supplemental
indenture or waiver under this Section 9.2 shall not:

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

                  (2)      reduce the stated rate of or extend the stated time
         for payment of interest, including default interest, on any Note;

                  (3)      reduce the principal of, any installment of interest
         on or any premium with respect to any Note, change the Stated Maturity
         of any Note or change the periods during which any Note may be redeemed
         in accordance with Section 3.7;

                                      -69-

<PAGE>

                  (4)      make any Note payable in currency other than that
         stated in the Note;

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

                  (6)      after the Company's obligation to purchase notes
         arises hereunder, amend, change or modify in any material respect in a
         manner adverse to the Holders of the obligation of the Company to make
         and consummate a Change of Control Offer in the event of a Change of
         Control or make and consummate an Asset Sale Offer with respect to any
         Asset Disposition that has been consummated or, after such Change of
         Control has occurred or such Asset Disposition has been consummated,
         modify any of the provisions or definitions with respect thereto;

                  (7)      reduce the percentage in principal amount of
         outstanding Notes the consent of the Holders of which is necessary to
         amend this Indenture, to waive compliance with certain provisions of
         this Indenture or to waive certain defaults; or

                  (8)      release any Guarantor from any of its obligations
         under the Subsidiary Guarantee or this Indenture, except as permitted
         hereunder.

                  Section 9.3.      Compliance with Trust Indenture Act.

                  Every amendment to or waiver of this Indenture or the Notes
shall be set forth in a supplemental indenture that complies with the TIA as
then in effect.

                  Section 9.4.      Revocation and Effect of Consents.

                  Until an amendment, supplemental indenture or waiver becomes
effective, a consent to it by a Holder of a Note is a continuing consent by the
Holder 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 or subsequent Holder may
revoke the consent as to his Note or portion of a Note if the Trustee receives
written notice of revocation before the date the amendment, supplemental
indenture or waiver becomes effective. An amendment, supplemental indenture or
waiver becomes effective in accordance with its terms and thereafter binds every
Holder.

                  The Company may, but shall not be obligated to, fix a record
date for the purpose of determining the Holders entitled to consent to any
amendment, supplemental indenture or waiver. If a record date is fixed, those
persons who were Holders at such record date (or their duly designated proxies),
and only those persons, shall be entitled to consent to such amendment,
supplemental indenture or waiver or to revoke any consent previously given,
whether or not such persons continue to be Holders after such record date. No
such consent shall be valid or effective for more than 120 days after such
record date.

                  Section 9.5.      Notation on or Exchange of Notes.

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

                  Section 9.6.      Trustee To Sign Amendments, etc.

                  The Trustee shall sign any amendment, waiver or supplemental
indenture authorized pursuant to this Article 9 if the amendment does not
adversely affect the rights, duties, liabilities or immunities of the Trustee.
If it does, the Trustee may, but need not, sign it. In signing or refusing to
sign such amendment, waiver or supplemental indenture, the Trustee shall be
provided with and, subject to Section 7.1, shall be fully protected in relying
upon, an Officers' Certificate and an Opinion of Counsel as conclusive evidence
that such amendment, waiver or supplemental indenture is authorized or permitted
by this Indenture, that it is not inconsistent herewith, and that it will be
valid and binding upon the Company in accordance with its terms.

                                   GUARANTEES

                  Section 10.1.     Subsidiary Guarantee.

                  Subject to the provisions of this Article 10, each Guarantor
in respect of the Notes hereby jointly and severally unconditionally guarantees,
on a senior unsecured basis, to each Holder of a Note authenticated and
delivered by the Trustee and to the Trustee and its successors, irrespective of
(i) the validity and enforceability of this Indenture, the Notes or the
obligations of the Company or any other Guarantors to the Holders of the Notes
or the Trustee hereunder or thereunder or (ii) the absence of any action to
enforce the same or any other circumstance which might otherwise constitute a
legal or equitable discharge or default of a Guarantor, that: (a) the principal
of, premium, if any, and interest with respect to the Notes shall be duly and
punctually paid in full when due, whether at maturity, by acceleration or
otherwise, and interest on the overdue principal and (to the extent permitted by
law) interest, if any, with respect to the Notes and all other obligations of
the Company or any Guarantor to the Holders of the Notes or the Trustee
hereunder or thereunder and all other obligations under this Indenture with
respect to the Notes or the Notes shall be promptly paid in full or performed,
all in accordance with the terms of this Indenture and thereof and (b) in case
of any extension of time of payment or renewal of any Notes or any of such other
obligations, the same shall 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 failing performance of any other obligation of the Company to
the Holders of the Notes, for whatever reason, each Guarantor shall be obligated
to pay, or to perform or cause the performance of, the same immediately. An
Event of Default under this Indenture or the Notes shall constitute an event of
default under the Subsidiary Guarantee, and shall entitle the Holders of Notes
or the Trustee to accelerate the obligations of the Guarantors of such Notes
hereunder in the same manner and to the same extent as the obligations of the
Company.

                                      -71-

<PAGE>

                  Each Guarantor, by execution of the Subsidiary Guarantee,
waives the benefit of diligence, presentment, demand for payment, filing of
claims with a court in the event of insolvency or bankruptcy of the Company, any
right to require a proceeding first against the Company, protest, notice and all
demands whatsoever and covenant that such Subsidiary Guarantee shall not be
discharged except by complete performance of the obligations contained in the
Notes, this Indenture and such Subsidiary Guarantee. The Subsidiary Guarantee is
a guarantee of payment and not of collection. If any Holder or the Trustee is
required by any court or otherwise to return to the Company or to any Guarantor,
or any custodian, trustee, liquidator or other similar official acting in
relation to the Company or such Guarantor, any amount paid by the Company or
such Guarantor to the Trustee or such Holder of the Notes, the Subsidiary
Guarantee, to the extent theretofore discharged, shall be reinstated in full
force and effect. Each Guarantor further agrees that, as between it, on the one
hand, and the Holders of the Notes and the Trustee, on the other hand, (a)
subject to this Article 10, the maturity of the obligations guaranteed hereby
may be accelerated as provided in Article 6 of this Indenture for the purposes
of the Subsidiary Guarantee, notwithstanding any stay, injunction or other
prohibition preventing such acceleration in respect of the obligations
guaranteed hereby and (b) in the event of any acceleration of such obligations
as provided in Article 6 of this Indenture, such obligations (whether or not due
and payable) shall forthwith become due and payable by the Guarantors for the
purpose of such Subsidiary Guarantee.

                  The Subsidiary Guarantee shall remain in full force and effect
and continue to be effective should any petition be filed by or against the
Company for liquidation or reorganization, should the Company become insolvent
or make an assignment for the benefit of creditors or should a receiver or
trustee be appointed for all or any significant part of the Company's assets,
and shall, to the fullest extent permitted by law, continue to be effective or
be reinstated, as the case may be, if at any time payment and performance of the
Notes are pursuant to applicable law, rescinded or reduced in amount, or must
otherwise be restored or returned by any obligee on the Notes, whether as a
"voidable preference," "fraudulent transfer" or otherwise, all as though such
payment or performance had not been made. In the event that any payment, or any
part thereof, is rescinded, reduced, restored or returned, the Notes shall, to
the fullest extent permitted by law, be reinstated and deemed reduced only by
such amount paid and not so rescinded, reduced, restored or returned.

                  No shareholder, officer, director, employee or incorporator,
past, present or future, or any Guarantor, as such, shall have any personal
liability under this Subsidiary Guarantee by reason of his, her or its status as
such shareholder, officer, director, employee or incorporator.

                  Section 10.2.     Execution and Delivery of Subsidiary
                                    Guarantee.

                  To further evidence the Subsidiary Guarantee set forth in
Section 10.1 of this Indenture, each Guarantor hereby agrees that a notation of
such Subsidiary Guarantee, substantially in the form included in Exhibit F to
this Indenture, shall be endorsed on each Note authenticated and delivered by
the Trustee after this Article 10 with respect to such Guarantor becomes
effective and such Subsidiary Guarantee shall be executed by either manual or
facsimile signature of an officer of each Guarantor. The validity and
enforceability of any Subsidiary Guarantee shall not be affected by the fact
that it is not affixed to any particular Note.

                                      -72-

<PAGE>

                  Each of the Guarantors hereby agrees that its Subsidiary
Guarantee set forth in Section 10.1 of this Indenture shall remain in full force
and effect notwithstanding any failure to endorse on each Note a notation of
such Subsidiary Guarantee.

                  If an officer of a Guarantor whose signature is on this
Indenture or a Subsidiary Guarantee no longer holds that office at the time the
Trustee authenticates the Note on which such Subsidiary Guarantee is endorsed or
at any time thereafter, such Guarantor's Subsidiary Guarantee of such Note shall
be valid nevertheless.

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

                  Section 10.3.     Limitation of Subsidiary Guarantee.

                  The obligations of each Guarantor are limited to the maximum
amount as shall, after giving effect to all other contingent and fixed
liabilities of such Guarantor and after giving effect to any collections from or
payments made by or on behalf of any other Guarantor in respect of the
obligations of such other Guarantor under its Subsidiary Guarantee or pursuant
to its contribution obligations under this Indenture, result in the obligations
of such Guarantor under the Subsidiary Guarantee not constituting a fraudulent
conveyance or fraudulent transfer under federal or state law. Each Guarantor
that makes a payment or distribution under a Subsidiary Guarantee shall be
entitled to a contribution from each other Guarantor in a pro rata amount based
on the net assets of each Guarantor, determined in accordance with GAAP.

                  Section 10.4.     Waiver of Subrogation.

                  Each Guarantor, by execution of its Subsidiary Guarantee,
waives to the extent permitted by law any claim or other rights which it may now
or hereafter acquire against the Company that arise from the existence, payment,
performance or enforcement of such Guarantor's obligations under such Subsidiary
Guarantee and this Indenture, including, without limitation, any right of
subrogation, reimbursement, exoneration, indemnification, and any right to
participate in any claim or remedy of any Holder of the Notes against the
Company, whether or not such claim, remedy or right arises in equity, or under
contract, statute or common law, including, without limitation, the right to
take or receive from the Company, directly or indirectly, in cash or other
property or by set-off or in any other manner, payment on account of such claim
or other rights. If any amount shall be paid to any Guarantor in violation of
the preceding sentence and the Notes shall not have been paid in full, such
amount shall have been deemed to have been paid to such Guarantor for the
benefit of, and held in trust for the benefit of, the Holders of the Notes, and
shall forthwith be paid to the Trustee for the benefit of such Holders to be
credited and applied upon the Notes, whether matured or unmatured, in accordance
with the terms of this Indenture. Each Guarantor, by execution of its Subsidiary
Guarantee, shall acknowledge that it shall receive direct and indirect benefits
from the financing arrangements contemplated by this Indenture and that the
waiver set forth in this Section 10.4 is knowingly made in contemplation of such
benefits.

                  Section 10.5.     Release of Subsidiary Guarantee.

                  If all or substantially all of the assets of any Guarantor or
all of the Capital Stock of any Guarantor is sold (including by consolidation,
merger, issuance or otherwise) or disposed of (including by liquidation,
dissolution or otherwise) by the Company or any of its Subsidiaries, or, unless
the Company elects otherwise, if any Guarantor is designated an Unrestricted
Subsidiary in accordance with Section 4.10, then such Guarantor (in the event of
a sale or other disposition of all of the Capital Stock of such Guarantor or a
designation as an Unrestricted Subsidiary) or the Person acquiring such assets
(in the event of a sale or other disposition of all or substantially all of the
assets of such Guarantor) shall be deemed automatically and unconditionally
released and discharged from any of its obligations under this Indenture without
any further action on the part of the Trustee or any Holder of the Notes;
provided, in each case that such Guarantor is no longer a Guarantor of, or
otherwise an obligor with respect to, any other Indebtedness of the Company. In
addition, if a Restricted Subsidiary is no longer a Guarantor of, or otherwise
an obligor with respect to, any other Indebtedness of the Company, such
Guarantor shall be deemed automatically and unconditionally released and
discharged from any of its obligations under this Indenture without any further
action on the part of the Trustee or any Holder of the Notes as long as no
Default or Event of Default has occurred and is continuing, or would occur as a
consequence thereof.

                  Section 10.6.     Contribution from Other Guarantors.

                  Each Guarantor that makes a payment or distribution under its
Subsidiary Guarantee shall be entitled to a contribution from each other
Guarantor in a pro rata amount based on the net assets of each Guarantor,
determined in accordance with GAAP, so long as the exercise of such right does
not impair the rights of Holders of Notes under any Subsidiary Guarantee.

                              6 1/2% Note Due 2014

1.       Interest

                  TRINITY INDUSTRIES, INC., a Delaware corporation (such
corporation, and its successors and assigns under this Indenture hereinafter
referred to, being herein called the "Company"), promises to pay interest on the
principal amount of this Note at the rate per annum shown above. The Company
will pay interest semiannually on March 15 and September 15 of each year,
commencing September 15, 2004. Interest on the Notes will accrue from the most
recent date to which interest has been paid or, if no interest has been paid,
from March 10, 2004. Interest will be computed on the basis of a 360-day year of
twelve-30-day months. The Company shall pay interest on overdue principal at the
rate borne by the Notes plus 1% per annum, and it shall pay interest on overdue
installments of interest at the same rate to the extent lawful.

2.       Method of Payment

                  The Company will pay interest on the Notes (except defaulted
interest) to the persons who are registered holders of Notes at the close of
business on the March 1 or September 1 next preceding the interest payment date
even if Notes are canceled after the record date and on or before the interest
payment date. Holders must surrender Notes to a Paying Agent to collect
principal payments. The Company will pay principal and interest in money of the
United States that at the time of payment is legal tender for payment of public
and private debts. However, the Company may pay principal and interest by check
payable in such money. It may mail an interest check to a Holder's registered
address.

3.       Paying Agent and Registrar

                  Initially, Wells Fargo Bank, National Association, a national
banking corporation (the "Trustee"), will act as Paying Agent and Registrar. The
Company may appoint and change any Paying Agent, Registrar or co-registrar
without notice. The Company or any of its Subsidiaries may act as Paying Agent,
Registrar or co-registrar.

4.       Indenture

                  The Company issued the Notes under an Indenture dated as of
March 10, 2004 (the "Indenture"), among the Company, the guarantors from time to
time party thereto and the Trustee. The terms of the Notes include those stated
in the Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939 (15 U.S.C. Sections 77aaa-77bbbb) as in effect on the date
of the Indenture (the "Act"). Capitalized terms used herein and not defined
herein have the meanings ascribed thereto in the Indenture. The Notes are
subject to all such terms, and Holders are referred to the Indenture and the Act
for a statement of those terms.

1.       Interest

                  TRINITY INDUSTRIES, INC., a Delaware corporation (such

principal amount of this Note at the rate per annum shown above. The Company
will pay interest semiannually on March 15 and September 15 of each year,
commencing September 15, 2004. Interest on the Notes will accrue from the most
recent date to which interest has been paid or, if no interest has been paid,
from March 10, 2004. Interest will be computed on the basis of a 360-day year of
twelve-30-day months. The Company shall pay interest on overdue principal at the
rate borne by the Notes plus 1% per annum, and it shall pay interest on overdue
installments of interest at the same rate to the extent lawful.

2.       Method of Payment

                  The Company will pay interest on the Notes (except defaulted
interest) to the persons who are registered holders of Notes at the close of
business on the March 1 or September 1 next preceding the interest payment date
even if Notes are canceled after the record date and on or before the interest
payment date. Holders must surrender Notes to a Paying Agent to collect
principal payments. The Company will pay principal and interest in money of the
United States that at the time of payment is legal tender for payment of public
and private debts. However, the Company may pay principal and interest by check
payable in such money. It may mail an interest check to a Holder's registered
address.

3.       Paying Agent and Registrar

Registrar or co-registrar.

                  The Company issued the Notes under an Indenture dated as of
March 10, 2004 (the "Indenture"), among the Company, the guarantors from time to
time party thereto and the Trustee. The terms of the Notes include those stated
in the Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939 (15 U.S.C. Sections 77aaa-77bbbb) as in effect on the date
of the Indenture (the "Act"). Capitalized terms used herein and not defined
herein have the meanings ascribed thereto in the Indenture. The Notes are
subject to all such terms, and Holders are referred to the Indenture and the Act
for a statement of those terms.

                  If money for the payment of principal, premium, if any, or
interest remains unclaimed for two years after the date on which such payment
became due, the Trustee and the Paying Agents will pay the money back to the
Company at its request. After that, all liability of the Trustee and such Paying
Agents with respect to such money shall cease, and Holders entitled to the money
must look only to the Company for payment.

11.      Defeasance

                  Subject to certain conditions, the Company at any time may
terminate some or all of its obligations under the Notes and the Indenture if

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

14.      Trustee Dealings with the Company

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

15.      No Recourse Against Others

                  A director, officer, employee or stockholder, as such, of the
Company or the Trustee shall not have any liability for any obligations of the
Company under the Notes or the Indenture or for any claim based on, in respect
of or by reason of such obligations or their creation. By accepting a Note, each
Holder waives and releases all such liability. The waiver and release are part
of the consideration for the issue of the Notes.

16.      Authentication

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

17.      Abbreviations

                  Customary abbreviations may be used in the name of a Holder or

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

18.      CUSIP Numbers

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

                  The Company will furnish to any Holder upon written request
and without charge to the Holder a copy of the indenture which has in it the
text of this Note in larger type. Requests

TRINITY INDUSTRIES, INC.
c/o WELLS FARGO BANK, NATIONAL ASSOCIATION
505 Main Street, Suite 301
Fort Worth, Texas 76102
Attention: Corporate Trust Administration

Ladies and Gentlemen:

                  This certificate is delivered to request a transfer of
$________ principal amount of the 6 1/2% Senior Notes due 2014 (the "Notes") of
TRINITY INDUSTRIES, INC. (the "Company"). Upon transfer, the Notes would be
registered in the name of the new beneficial owner as follows:

                  Name: _______________________________________
                  Address: ____________________________________
                  Taxpayer ID Number: _________________________

                  The undersigned represents and warrants to you that:

                  1.       We are an institutional "accredited investor" (as
defined in Rule 501(a)(1), (2), (3) or (7) under the Securities Act of 1933 (the
"Securities Act")) purchasing for our own account or for the account of such an
institutional "accredited investor" at least $100,000 principal amount of the
Notes, and we are acquiring the Notes not with a view to, or for offer or sale
in connection with, any distribution in violation of the Securities Act. We have
such knowledge and experience in financial and business matters as to be capable
of evaluating the merits and risk of our investment in the Notes and we invest
in or purchase securities similar to the Notes in the normal course of our
business. We and any accounts for which we are acting are each able to bear the
economic risk of our or its investment.

                  2.       We understand that the Notes have not been registered
under the Securities Act and, unless so registered, may not be sold except as
permitted in the following sentence. We agree on our own behalf and on behalf of
any investor account for which we are purchasing Notes to offer, sell or
otherwise transfer such Notes prior to the date which is two years after the
later of the date of original issue and the last date on which the Company or
any affiliate of the Company was the owner of such Notes (or any predecessor
thereto) (the "Resale Restriction Termination Date") only (a) to the Company,
(b) pursuant to a registration statement which has been declared effective under
the Securities Act, (c) in a transaction complying with the requirements of Rule
144A under the Securities Act, to a person we reasonably believe is a qualified
institutional buyer under Rule 144A (a "QIB") that purchases for its own account
or for the account of a QIB and to whom notice is given that the transfer is
being made in reliance on Rule 144A, (d) pursuant to offers and sales that occur
outside the United States within the meaning of Regu-

                                      D-1

lation S under the Securities Act, (e) to an institutional "accredited investor"
within the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act
that is purchasing for its own account or for the account of such an
institutional "accredited investor," in each case in a minimum principal amount
of Notes of $100,000, or (f) pursuant to any other available exemption from the
registration requirements of the Securities Act, subject in each of the
foregoing cases to any requirement of law that the disposition of our property
or the property of such investor account or accounts be at all times within our
or their control and in compliance with any applicable state securities laws.
The foregoing restrictions on resale will not apply subsequent to the Resale
Restriction Termination Date. If any resale or other transfer of the Notes is
proposed to be made pursuant to clause (e) above prior to the Resale Restriction
Termination Date, the transferor shall deliver a letter from the transferee
substantially in the form of this letter to the Company and the Trustee, which
shall provide, among other things, that the transferee is an institutional
"accredited investor" within the meaning of Rule 501(a)(1), (2), (3) or (7)
under the Securities Act and that it is acquiring such Notes for investment
purposes and not for distribution in violation of the Securities Act. Each
purchaser acknowledges that the Company and the Trustee reserve the right prior
to any offer, sale or other transfer prior to the Resale Restriction Termination
Date of the Notes pursuant to clause (d), (e) or (f) above to require the
delivery of an opinion of counsel, certificates and/or other information
satisfactory to the Company and the Trustee.

                  In connection with our proposed sale of $            aggregate
principal amount of the Notes, we confirm that such sale has been effected
pursuant to and in accordance with Regulation S under the Securities Act of
1933, as amended (the "Securities Act"), and, accordingly, we represent that:

         the United States;

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

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

                  (4)      the transaction is not part of a plan or scheme to
         evade the registration requirements of the Securities Act; and

are irrevocably authorized to produce this letter or a copy hereof to any
