     (a) To the extent not prohibited by any applicable law or applicable

     (iv) that any Holder electing to have a Registrable Security exchanged

          Registrable Security, together with the appropriate letters of
          transmittal, to the institution and at the address (located in the
          Borough of Manhattan, The City of New York) and in the manner
          specified in the notice, prior to the close of business on the last
          Exchange Date; and

     (v)  that any Holder will be entitled to withdraw its election, not later
          than the close of business on the last Exchange Date, by sending to
          the institution and at the address (located in the Borough of
          Manhattan, The City of New York) specified in the notice, a telegram,
          telex, facsimile transmission or letter setting forth the name of such
          Holder, the amount of Registrable Securities delivered for exchange
          and a statement that such Holder is withdrawing its election to have
          such Registrable Securities exchanged.

     As a condition to participating in the Exchange Offer, a Holder will be
required to represent to the Company 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 Offer it has no arrangement or
understanding with any Person to participate in the distribution (within the
meaning of the Securities Act) of the Exchange Securities in violation of the
provisions of the Securities Act, (iii) it is not an "affiliate" (within the
meaning of Rule 405 under Securities Act) of the Company and (iv) if such Holder

mar-

ket-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 shall:

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     validly tendered and not properly withdrawn pursuant to the Exchange Offer;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

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

     The Company shall use its 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.

     (b) In the event that (i) the Company determines that the Exchange Offer
Registration provided for in Section 2(a) above is not available or may not be
completed as soon as practicable after the last Exchange Date because it would
violate any applicable law or applicable interpretations of the Staff, (ii) the
Exchange Offer is not for any other reason completed by 210 days after the
Trigger Date or (iii) the Exchange Offer has been completed and in the opinion
of counsel for the Initial Holder a Registration Statement must be filed and a
Prospectus must be delivered by the Initial Holder in connection with any
offering or sale of Registrable Securities held by the Initial Holder, the
Company shall use its reasonable best efforts to cause to be filed as soon as
practicable after such determination, date or notice of such opinion of counsel
is given to the Company, as the case may be, a Shelf Registration Statement
providing for the sale of all the Registrable Securities by the Holders thereof
(or Initial Holder that is a holder thereof in the case of a Shelf Registration
Statement filed pursuant to clause (iii) of this sentence) and to have such
Shelf Registration Statement declared effective by the SEC.

     In the event that the Company is required to file a Shelf Registration
Statement solely as a result of the matters referred to in clause (iii) of the
preceding sentence, the Company shall use its reasonable best efforts to file
and have declared effective by the SEC both an Exchange Offer Registration
Statement pursuant to Section 2(a) with respect to all Registrable Securities
and a Shelf Registration Statement (which may be a combined Registration
Statement with the Exchange Offer Registration Statement) with respect to offers
and sales of Registrable Securities held by the Initial Holder after completion
of the Exchange Offer. The Company agrees to use its 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
Company further agrees 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

                                      -6-
<PAGE>

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 its 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 agrees 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 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; provided that if, after it has been declared effective, the offering of
Registrable Securities pursuant to a Shelf Registration Statement is interfered
with by any stop order, injunction or other order or requirement of the SEC or
any court or other governmental or regulatory agency or body, such Registration
Statement will be deemed not to have become effective during the period of such
interference until the offering of Registrable Securities pursuant to such
Registration Statement may legally resume.

     In the event that either the Exchange Offer is not completed or a Shelf
Registration Statement, if required hereby, is not declared effective by the SEC
within 210 days of the Trigger Date, Holders of Registrable Securities will be
entitled to liquidated damages on each share of Registrable Securities equal to
$0.25 for each 90-day period (pro rated based on the number of days actually
elasped) until the Exchange Offer is completed or the Shelf Registration
Statement, if required hereby, is declared effective by the SEC or the
Registrable Securities become freely tradable under the Securities Act (the
period beginning on the 211th day after the Trigger Date and ending on the date
of completion of the Exchange Offer or the effective date of the Shelf
Registration Statement or the date on which the Registrable Securities become
freely tradable under the Securities Act, as the case may be, the "Default
Period"); provided, however, that if, for any reason, the Company does not pay
such liquidated damages within five Business Days after the end of the Default
Period, the dividend rate or interest rate, as applicable, on the Registrable
Securities will be deemed to have been increased by 1.00% per annum during the
Default Period (and the Company shall be released from its obligation to pay
such liquidated damages).

     (e) Without limiting the remedies available to the Initial Holder and the
Holders, the Company acknowledges that any failure by the Company to comply with
its obligations under Section 2(a) and Section 2(b) hereof may result in
material irreparable injury to the Initial Holder 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 Holder or any Holder may obtain such relief as may be required to
specifically enforce the Company's obligations under Section 2(a) and Section
2(b) hereof.

                                      -10-
<PAGE>

     (o) as soon as reasonably practicable following the end of any fiscal year
during which a Registration Statement shall have been effective, to make
available to its security holders an earnings statement satisfying the
provisions of Section 11(a) of the Securities Act;

     (p) in the case of a Shelf Registration, cooperate with the Holders to
facilitate the timely preparation and delivery of certificates representing the
Registrable Securities sold pursuant to a Shelf Registration Statement and not
bearing any restrictive legend and to enable certificates for such Registrable
Securities to be issued in such denominations and registered in such names as
the Holders may reasonably request; and

     (q) 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 (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, if
necessary, any other certified public accountant of any subsidiary of the
Company, or of any business acquired by the Company 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 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 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 may from time to time reasonably request
in writing.

     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 and shall be reasonably
acceptable to the Company.

                                      -11-
<PAGE>

     At the time of any registration of Securities under this Agreement, the
Company shall simultaneously register the Exchange Notes under the same
Registration Statement that covers the Securities and qualify the Exchange
Indenture under the Trust Indenture Act so as to permit the issuance of the
Exchange Notes on a registered basis should the Company subsequently exercise
its rights under Section 4 of the Certificate of Designation to effect the
exchange of the Securities and Series A-2 Preferred Stock for the Exchange Notes
as provided in Section 4 of the Certificate of Designation.

Section 4. Suspension.

     (a) Notwithstanding any of the other provisions of this Agreement, but
subject to Section 4(c) hereof, in the case of a Shelf Registration Statement,
each Holder of Registrable Securities agrees that, upon receipt of a written
notice from the Company 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 such Shelf 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, such Holder will deliver to the Company 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 written notice. If the Company shall give any such
written notice to suspend the disposition of Registrable Securities pursuant to
a Registration Statement pursuant to this Section 4(a), the Company 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.

     (b) Notwithstanding any of the other provisions of this Agreement, but
subject to Section 4(c) hereof, the Company shall have the right on one or more
occasions to delay the filing, amendment or effectiveness of a Shelf
Registration Statement or, if the Shelf Registration Statement has become
effective, to suspend the distribution or disposition of each Holder's
Registrable Securities pursuant to such Registration Statement in the event that
the board of directors of the Company determines in its reasonable good faith
judgment that (i) the filing, declaration of effectiveness or continued
effectiveness of such Shelf Registration Statement at such time would require
the Company to disclose therein a proposed or consummated financing,
reorganization or recapitalization, or pending or consummated negotiations
relating to a merger, consolidation, acquisition or similar transaction or other
business transaction, or other material event, which would otherwise adversely
affect the Company or (ii) pro forma and/or historical financial statements
meeting the requirements of the Securities Act as a result of any transaction
described in clause (i) above are not available at such time. Any delay or
suspension period pursuant to this Section 4(b) shall begin on the date
specified in a written notice given by the Company to the Holders and shall end
on the date specified in a subsequent written notice given by the Company to the
Holders. If the Company shall exercise its right to delay the filing, amendment
or effectiveness of a Shelf Registration Statement or to suspend the
distribution or disposition of each Holder's Registrable Securities pursuant to
such Registration Statement pursuant to this Section 4(b), the period within
which such Shelf Registration Statement must be declared effective or during
which the effectiveness of such Shelf Registration Statement must be maintained

                                      -12-
<PAGE>

pursuant to this Agreement shall be extended by the number of days of the delay
or suspension period.

     (c) The Company may give a delay or suspension notice pursuant to Section 4
hereof at any time and from time to time; provided that the aggregate of all
delay and suspension periods during any 365-day period shall not exceed 90 days.

Section 5. Other Rights.

     (a) Board Observer Rights. Subject to Sections 5(c), 5(d) and 5(e) below,
for so long as the Initial Holder and its Affiliates beneficially own at least
$5 million in initial aggregate liquidation preference of Securities or Series
A-2 Preferred Stock, the Initial Holder shall be entitled to designate one
representative to (i) receive notices of meetings of the Company's Board of
Directors at the same time and in the same manner that the members of the
Company's Board of Directors shall receive such notices, (ii) attend such
meetings and (iii) receive copies of any materials provided to the members of
the Company's Board of Directors except to the extent that such materials relate
to matters described in Section 5(c) below. The observer rights provided by this
Section 5(a) may be declined by the Initial Holder in its sole discretion for
such period or periods of time as it wishes; provided that no such decline shall
prevent the Initial Holder from electing to exercise such observer rights in
future periods. The observer rights provided by this Section 5(a) shall not be
assignable to any Person, except to Affiliates of the Initial Holder.

     (b) Information Rights. Subject to Sections 5(c), 5(d) and 5(e) below, for
so long as the Initial Holder and its Affiliates beneficially own at least $5
million in initial aggregate liquidation preference of Securities or Series A-2
Preferred Stock, the Initial Holder will be entitled to receive (i) annual
consolidated balance sheets and statements of income, stockholders' equity and
cash flows of the Company within 90 days after the end of each fiscal year of
the Company, prepared in accordance with GAAP; (ii) quarterly consolidated
balance sheets and statements of income, stockholders' equity and cash flows of
the Company within 45 days after the end of each fiscal quarter of the Company,
prepared in accordance with GAAP; and (iii) such other information as the
Initial Holder may from time to time reasonably request concerning the condition
or operations, financial or otherwise, of the Company; provided, however, that
the Company will not be required to provide the Initial Holder with the
information contemplated by clauses (i) and (ii) above during any period in
which the Company is subject to and in compliance with Section 13 or 15(d) of
the Exchange Act.

     (c) Exclusion. Notwithstanding Section 5(a) above, the Company shall be
permitted to notify the Initial Holder and its Affiliates that they are to be
excluded from any meeting (or any portion thereof) of the Company's Board of
Directors that (i) involves matters relating to competitors of the Initial
Holder or its Affiliates, (ii) involves matters pertaining to the Company's
relationship with the Initial Holder or its Affiliates, (iii) based upon advice
of counsel, raises anti-competitive or antitrust concerns, or similar concerns
under any laws or policies of any government or instrumentality thereof or (iv)
otherwise involves matters that, in the reasonable judgment of the Company, if
known to the Initial Holder or its Affiliates, could have an adverse impact on
the Company's business, commercial relationships or business plans or
strategies.

                                      -13-
<PAGE>

     (d) Confidentiality; Limitations on Use. Notwithstanding Sections 5(a) and
5(b) above, the Initial Holder agrees that neither it nor any of its
representatives will (i) disclose to any third party any information provided to
it or any of its representatives by the Company hereunder which is not generally
available to the public, except with the prior express approval of the Company
or as may be required by applicable law or (ii) use any information provided to
it or any of its representatives by the Company hereunder for any purpose other
than monitoring its investment in the Securities or Series A-2 Preferred Stock.

     Notwithstanding anything herein to the contrary, any party to this
Agreement (and any employee, representative, or other agent of any party to this
Agreement) may disclose to any and all persons, without limitation of any kind,
the tax treatment and tax structure of the transactions contemplated by this
Agreement (individually and collectively, the "Contemplated Transaction") and
all materials of any kind (including opinions or other tax analyses) that are
provided to it relating to such tax treatment and tax structure.

     Notwithstanding Sections 5(a) and 5(b) above, access to highly confidential
proprietary information and facilities need not be provided by the Company, nor
shall the Company be required to provide information to the Initial Holder or
any other Holder that is a competitor (or an Affiliate of a competitor) or
reasonably likely to become a competitor (or an Affiliate of a competitor) of
the Company or any of its subsidiaries. (e) No Liability for Insider Trading.
Notwithstanding any other provision of this Agreement, in no event shall the
Company or any of its Affiliates be responsible for any liability to which any
Holder or any of its Affiliates may be subject by reason of trading in
securities of the Company at a time when it is in possession of material
non-public information.

Section 6. Indemnification and Contribution.

     (a) The Company agrees to indemnify and hold harmless the Initial Holder
and each Holder, their respective Affiliates and each Person, if any, who
controls the Initial Holder 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), joint or several, (i) arising out of or based
upon any untrue statement or alleged untrue statement of a material fact
contained in any Registration Statement or any Prospectus, (ii) arising out of
or based upon 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 are
arising out of or 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 the Initial Holder or any Holder furnished to the
Company in writing through the Initial Holder or any selling Holder expressly
for use therein. In connection with any Underwritten Offering permitted by
Section 3, the Company 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

                                      -14-
<PAGE>

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 Initial Holder and the other selling Holders, their
respective Affiliates, the directors of the Company, each officer of the Company
who signed the Registration Statement and each Person, if any, who controls the
Company, the Initial Holder 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 arising out of or based upon any
untrue statement or omission or alleged untrue statement or omission made in
reliance upon and in conformity with any information relating to such Holder
furnished to the Company in writing by such Holder expressly for use in any
Registration Statement 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 that the failure to notify the
Indemnifying Person shall not relieve it from any liability that it may have
under this Section 6 except to the extent that it has been materially prejudiced
(through the forfeiture of substantive rights or defenses) by such failure; and
provided, further, that the failure to notify the Indemnifying Person shall not
relieve it from any liability that it may have to an Indemnified Person
otherwise than under this Section 6. If any such proceeding shall be brought or
asserted against an Indemnified Person and it shall have notified the
Indemnifying Person thereof, the Indemnifying Person shall retain counsel
reasonably satisfactory to the Indemnified Person to represent the Indemnified
Person and any others entitled to indemnification pursuant to this Section 6
that the Indemnifying Person may designate in such proceeding and shall pay the
fees and expenses of such counsel related to such proceeding. 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 the Initial Holder, its Affiliates and
any control Persons of such Initial Holder shall be designated in writing by the
Initial Holder, (y) for any Holder, its Affiliates 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

                                      -15-
<PAGE>

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
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 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 from the offering of the 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 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 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 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 and the Holders agree that it would not be just and
equitable if contribution pursuant to this Section 6 were determined by pro rata
allocation (even if the Holders were treated as one entity for such purpose) or
by any other method of allocation that does not take account of the equitable
considerations referred to in paragraph (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 6, in no event shall a Holder be required to
contribute any amount in excess of the amount by which the total price at which
the Securities or Exchange Securities sold by such Holder exceeds the amount of
any damages that such Holder has otherwise been required to pay by reason of
such untrue or alleged untrue statement or omission or alleged omission. No
Person guilty of fraudulent misrepresentation

                                      -16-
<PAGE>

(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 6 are not exclusive and shall
not limit any rights or remedies that may otherwise be available to any
Indemnified Person at law or in equity.

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

Section 7. Miscellaneous.

     (a) No Inconsistent Agreements. The Company represents, warrants and agrees
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 under any other
agreement and (ii) the Company has not 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 has 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 that no amendment, modification, supplement, waiver or consent to any
departure from the provisions of Section 6 hereof shall be effective as against
any Holder of Registrable Securities unless consented to in writing by such
Initial Holder.

     (c) Notices. All notices and other communications provided for or permitted
hereunder shall be made in writing by hand-delivery, registered first-class
mail, telex, telecopier, or any courier guaranteeing overnight delivery (i) if

deposited in the mail, postage prepaid, if mailed; when answered back, if
telexed; when receipt is acknowledged, if telecopied; and on the next Business
Day if timely delivered to an air courier guaranteeing overnight delivery.

     (d) Successors and Assigns. This Agreement shall inure to the benefit of
and be binding upon the successors, assigns and transferees of each of the
parties, including, without limitation and without the need for an express
assignment, subsequent Holders; provided that nothing herein shall be deemed to
permit any assignment, transfer or other disposition of Registrable Securities
in violation of the terms of the Purchase Agreement. If any transferee of any
Holder shall acquire Registrable Securities in any manner, whether by operation
of law or otherwise, such Registrable Securities shall be held subject to all
the terms of this Agreement, and by taking and holding such Registrable
Securities such Person shall be conclusively deemed to have agreed to be bound
by and to perform all of the terms and provisions of this Agreement and such
Person shall be entitled to receive the benefits hereof. The Initial Holder (in
its capacity as Initial Holder) shall have no liability or obligation to the
Company with respect to any failure by a Holder to comply with, or any breach by
any Holder of, any of the obligations of such Holder under this Agreement.

     (e) Purchases and Sales of Registrable Securities. The Company shall not,
and shall use its reasonable best efforts to cause its affiliates (as defined in
Rule 405 under the Securities Act) not to, purchase and then resell or otherwise
transfer any Registrable Securities.

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

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

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

     (i) GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK. THE COMPANY HEREBY AGREES TO
SUBMIT TO THE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK, COUNTY OF NEW
YORK, IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT.

     (j) Miscellaneous. This Agreement contains the entire agreement between the
parties relating to the subject matter hereof and supersedes all oral statements
and prior writings with

                                      -18-
<PAGE>

respect thereto. This Agreement may not be amended or modified except by a
writing executed by each of the parties hereto. Section headings herein are for
convenience only and are not a part of this Agreement. 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 and the Initial Holder 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.

Holders (as defined below) of the 10% Series A Senior Subordinated Notes due

                                   ARTICLE 1.

                          DEFINITIONS AND INCORPORATION
                                  BY REFERENCE

     Section 1.01 Definitions.

     "2002 Indenture" means the Indenture, dated as of June 20, 2002, by and

     "2012 Notes" means the Company's 11% senior subordinated notes due 2012
issued from time to time under the 2002 Indenture.

     "Acquired Debt" means, with respect to any specified Person:

          (1) Indebtedness of any other Person existing at the time such other
     Person is merged with or into or became a Subsidiary of such specified
     Person, whether or not such Indebtedness is incurred in connection with, or
     in contemplation of, such other Person merging with or into, or becoming a
     Subsidiary of, such specified Person; and

          (2) Indebtedness secured by a Lien encumbering any asset acquired by
     such specified Person.

     "Adjusted Treasury Rate" means, with respect to any redemption date, the

Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue
(expressed as a percentage of its principal amount) equal to the Comparable
Treasury Price for such redemption date, plus 50 basis points.

     "Advisory Agreement" means that certain monitoring agreement between the
Company and Heartland, as in effect on the date of this Indenture, or any

as used with respect to any Person, means the possession,

<PAGE>

directly or indirectly, of the power to direct or cause the direction of the
management or policies of such Person, whether through the ownership of voting
securities, by agreement or otherwise. For purposes of this definition, the
terms "controlling," "controlled by" and "under common control with" have
correlative meanings. No Person (other than the Company or any Subsidiary of the
Company) in whom a Receivables Subsidiary makes an Investment in connection with
a Qualified Receivables Transaction will be deemed to be an Affiliate of the
Company or any of its Subsidiaries solely by reason of such Investment.

     "Agent" means any Registrar, co-registrar, Paying Agent or additional

     "Applicable Procedures" means, with respect to any transfer or exchange of

     "Asset Sale" means:

          (1) the sale, lease conveyance or other disposition of any assets or
     rights, other than dispositions in the ordinary course of business;
     provided that the sale, conveyance or other disposition of all or
     substantially all of the assets of the Company and the Restricted
     Subsidiaries taken as a whole will be governed by Section 4.14 hereof
     and/or Section 5.01 hereof and not by Section 4.10 hereof; and

          (2) the issuance of Equity Interests in any of the Restricted
     Subsidiaries or the sale of Equity Interests in any of the Restricted
     Subsidiaries.

     Notwithstanding the preceding, none of the following items will be deemed
to be an Asset Sale:

          (1) any single transaction or series of related transactions that
     involves assets having a fair market value of less than $2.5 million;

          (2) a transfer of assets between or among the Company and the
     Restricted Subsidiaries;

          (3) an issuance of Equity Interests by a Subsidiary to the Company or

     shares;

          (4) the sale or other disposition of cash or Cash Equivalents;

          (5) sales of accounts receivable and related assets of the type

or usage. Each Note will be dated the date of its authentication. The Notes

     Section 2.02 Execution and Authentication.

     One Officer must sign 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 a Note is authenticated, the Note will nevertheless be valid.

     Except for Notes issued prior to the appointment of the Trustee under
Section 7.01(a), a Note will not be valid until authenticated by the manual
signature of the Trustee. The signature, if required, will be conclusive
evidence that the Note has been authenticated under this Indenture. Following
such appointment of the Trustee, the Company will be required to exchange Notes
so authenticated for previously issued non-authenticated Notes within a
reasonable period of time following a written request by a Holder that has
delivered all reasonably required documentation, including the non-authenticated
Note, subject to the provisions applicable to Global Notes. The absence of an
authentication on a Note issued prior to the appointment of a Trustee will not
affect the validity of the enforceability of the Note.

     If required, the Trustee shall, upon written order of the Company signed by
an Officer (an "Authentication Order"), authenticate Notes for original or
replacement issue of up to $31,746,000 in aggregate principal amount and, upon
delivery of any Authentication Order at any time and from time to time
thereafter, the Trustee shall authenticate Notes and Exchange Notes for original
issue in an aggregate principal amount specified in such Authentication Order.

     The Trustee may appoint an authenticating agent acceptable to the Company
to authenticate Notes. An authenticating agent may authenticate Notes whenever
the Trustee may do so. Each reference in this Indenture to authentication by the
Trustee includes authentication by such agent. An authenticating agent has the
same rights as an Agent to deal with Holders or an Affiliate of the Company.

     Section 2.03 Registrar and Paying Agent.

     The Company will maintain an office or agency where Notes may be presented
for registration of transfer or for exchange ("Registrar") and an office or
agency where Notes may be presented for payment ("Paying Agent"). The Registrar
will keep a register of the Notes and of their transfer and exchange. The
Company may appoint one or more co-registrars and one or more additional paying
agents. The term "Registrar" includes any co-registrar and the term "Paying
Agent" includes any additional paying agent. The Company may change any Paying
Agent or Registrar without notice to any Holder. The Company will notify the
Trustee in writing 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 (and shall initially) act as Paying Agent or Registrar.

     The Company initially appoints The Depository Trust Company ("DTC") to act
as Depositary with respect to any Global Note, effective upon issuance of such
Global Note.

     The Company will initially appoint the Trustee, upon issuance of any Global
Note, to act as Custodian with respect to such Global Notes.

     Section 2.04 Paying Agent to Hold Money in Trust.

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

     Section 2.05 Holder Lists.

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

by a nominee of the Depositary to the Depositary or to another nominee of the
Depositary, or by the Depositary or any such nominee to a successor Depositary
or a nominee of such successor Depositary. All Global Notes will be exchanged by

     that it is unwilling or unable to continue to act as Depositary or that it

     120 days after the date of such notice from the Depositary; or

     Notes (in whole but not in part) should be exchanged for Definitive Notes
     and delivers a written notice to such effect to the Trustee.

     Upon the occurrence of either of the preceding events in (1) or (2) above,
Definitive Notes shall be issued in such names as the Depositary shall instruct
the Trustee. Global Notes also may be exchanged or replaced, in whole or in
part, as provided in Sections 2.07 and 2.10 hereof. Every Note authenticated and
delivered in exchange for, or in lieu of, a Global Note or any portion thereof,
pursuant to this Section 2.06 or Section 2.07 or 2.10 hereof, shall be
authen-

               a certificate from such Holder in the form of Exhibit B hereto,
               including the certifications in item (4) thereof;

          and, in each such case set forth in this subparagraph (D), if the
          Registrar so requests, an Opinion of Counsel in form reasonably

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

     (i) General Provisions Relating to Transfers and Exchanges.

               (1) To permit registrations of transfers and exchanges, the

          Global Notes and Definitive Notes upon receipt of an Authentication
          Order in accordance with Section 2.02 or at the Registrar's request.

               (2) No service charge will be made to a Holder of a Global Note
          or to a Holder of a Definitive Note for any registration of transfer
          or exchange, but the Company may require payment of a sum sufficient
          to cover any transfer tax or similar governmental charge payable in
          connection therewith (other than any such transfer taxes or similar
          governmental charge payable upon exchange or transfer pursuant to
          Sections 2.10, 3.06, 3.09, 4.10, 4.14 and 9.05 hereof). The Registrar
          will not be required to register the transfer of or exchange any Note
          selected for redemption in whole or in part, except the unredeemed
          portion of any Note being redeemed in part.

                                      -36-

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

               (4) The Company will not be required:

                    (A) to issue, to register the transfer of or to exchange any
               Notes during a period beginning at the opening of business 15
               days before the day of any selection of Notes for redemption
               under Section 3.02 hereof and ending at the close of business on
               the day of selection;

                    (B) to register the transfer of or to exchange any Note
               selected for redemption in whole or in part, except the
               unredeemed portion of any Note being redeemed in part; or

                    (C) to register the transfer of or to exchange a Note
               between a record date and the next succeeding interest payment
               date.

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

          (6) The Trustee (if appointed) will authenticate Global Notes and
     Definitive Notes in accordance with the provisions of Section 2.02 hereof.

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

     Section 2.07 Replacement Notes.

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

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

                                      -37-

     Section 2.08 Outstanding Notes.

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

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

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

     If the Paying Agent (other than the Company, a Subsidiary or an Affiliate
of any thereof) holds, on a redemption date or maturity date, money sufficient
to pay Notes payable on that date, then on and after that date such Notes will
be deemed to be no longer outstanding and will cease to accrue interest.

     Section 2.09 Treasury Notes.

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

     Section 2.10 Temporary Notes.

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

     Holders of temporary notes will be entitled to all of the benefits of this
Indenture.

     Section 2.11 Cancellation.

     The Company at any time may deliver Notes to the Trustee for cancellation,
or if a Trustee is not appointed, it may cancel Notes. If a Trustee has been
appointed, the Registrar and Paying Agent will forward to the Trustee any Notes
surrendered to them for registration of transfer,

                                      -38-
<PAGE>

exchange or payment. If a Trustee has been appointed, the Trustee and no one
else will cancel all Notes surrendered for registration of transfer, exchange,
payment, replacement or cancellation and will dispose of canceled Notes (subject
to the record retention requirement of the Exchange Act). The Company may not
issue new Notes to replace Notes that it has paid or that have been delivered to
the Trustee for cancellation or have been cancelled.

     Section 2.12 Defaulted Interest.

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

     Section 2.13 CUSIP Numbers.

     The Company in issuing the Notes may use "CUSIP" numbers (if then generally
in use), and, if so, "CUSIP" numbers shall be used 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 will promptly notify the Trustee (if any) of any change in
the "CUSIP" numbers.

     Section 3.02 Selection of Notes to Be Redeemed or Purchased.

     If less than all of the Notes are to be redeemed or purchased in an offer
to purchase at any time, the Trustee (or, if no Trustee has been appointed, the
Company) will select Notes for redemption or purchase as follows:

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

          (2) if the Notes are not listed on any national securities exchange,
     on a pro rata basis, by lot or by such method as the Trustee (or, if no
     Trustee has been appointed, the Company) shall deem fair and appropriate.

     In the event of partial redemption or purchase by lot, the particular Notes
to be redeemed or purchased will be selected, unless otherwise provided herein,
not less than 30 nor more than 60 days prior to the redemption or purchase date
by the Trustee (or, if no Trustee has been appointed, by the Company) from the
outstanding Notes not previously called for redemption or purchase.

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

     Section 3.03 Notice of Redemption.

     Subject to the provisions of Section 3.09 hereof, at least 30 days but not
more than 60 days before a redemption date, the Company will mail or cause to be
mailed, by first class mail, a notice of redemption to each Holder whose Notes
are to be redeemed at its registered address, except that redemption notices may
be mailed more than 60 days prior to a redemption date if the notice is issued
in connection with a defeasance of the Notes or a satisfaction and discharge of
this Indenture pursuant to Article 8 or 12 of this Indenture.

     The notice will identify the Notes to be redeemed (including the CUSIP or
ISIN number) and will state:

          (1) the redemption date;

          (2) the redemption price;

          (3) if any Note is being redeemed in part, the portion of the
     principal amount of such Note to be redeemed and that, after the redemption
     date upon surrender of such

                                      -40-
<PAGE>

     Note, a new Note or Notes in principal amount equal to the unredeemed
     portion will be issued upon cancellation of the original Note;

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

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

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

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

          (8) 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, if a Trustee has been appointed, the Trustee will
give the notice of redemption in the Company's name and at its expense;
provided, however, that the Company has delivered to the Trustee, at least 45
days prior to the redemption date, an Officers' Certificate requesting that the
Trustee give such notice and setting forth the information to be stated in such
notice as provided in the preceding paragraph.

     Section 3.04 Effect of Notice of Redemption.

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

     Section 3.05 Deposit of Redemption or Purchase Price.

     Prior to 10:00 a.m. (Eastern Time) on the redemption or purchase price
date, the Company will deposit with the Trustee or with the Paying Agent money
sufficient to pay the redemption or purchase price of and accrued interest and
Liquidated Damages, if any, on all Notes to be redeemed or purchased on that
date. The Trustee or the Paying Agent will promptly return to the Company any
money deposited with the Trustee or the Paying Agent by the Company in excess of
the amounts necessary to pay the redemption or purchase price of, and accrued
interest and Liquidated Damages, if any, on, all Notes to be redeemed or
purchased.

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

                                      -41-
<PAGE>

until such principal is paid, and to the extent lawful on any interest not paid
on such unpaid principal, in each case at the rate provided in the Notes and in
Section 4.01 hereof.

     Section 3.06 Notes Redeemed or Purchased in Part.

     Upon surrender of a Note that is redeemed or purchased in part, the Company
will issue and, if a Trustee has been appointed, upon receipt of an
Authentication Order, the Trustee will authenticate for the Holder at the
expense of the Company a new Note equal in principal amount to the unredeemed or
unpurchased portion of the Note surrendered.

     Section 3.07 Optional Redemption.

     (a) The Notes will not be subject to any redemption at the option of the
Company except as set forth in the following paragraphs.

     (b) The Notes may be redeemed, in whole part or in part, at any time prior
to January 15, 2009, at the option of the Company upon not less than 30 nor more
than 60 days' prior notice mailed by first-class mail to each Holder's
registered address, at a redemption price equal to, as determined by the
Reference Treasury Dealer, the sum of the present values of the Remaining
Scheduled Payments discounted to the redemption date on a semiannual basis
(assuming a 360-day year consisting of twelve 30-day months) at the Adjusted
Treasury Rate, plus accrued and unpaid interest and Liquidated Damages, if any,
to the applicable date of redemption.

     (c) At any time prior to January 15, 2009, the Company may on any one or
more occasions redeem up to 35% of the aggregate principal amount of Notes
issued under this Indenture at a redemption price of 110% of the principal
amount thereof, plus accrued and unpaid interest and Liquidated Damages, if any,
to the redemption date, with the net cash proceeds of one or more Equity
Offerings; provided that:

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

                    (2) the redemption must occur within 120 days of the date of
               the closing of such Equity Offering.

     (d) After January 15, 2009, the Company may redeem all or a part of the
Notes upon not less than 30 nor more than 60 days' notice, at the redemption
prices (expressed as percentages of principal amount) set forth below plus
accrued and unpaid interest and Liquidated Damages, if any, thereon to the
applicable redemption date, if redeemed during the twelve-month period beginning
on January 15th of the years indicated below:

        Year                                             Percentage
        ----                                             ----------

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

     Section 3.08 Mandatory Redemption.

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

     Section 3.09 Offer to Purchase by Application of Excess Proceeds.

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

     The Asset Sale Offer shall be made to all Holders and all holders of other
Indebtedness that is pari passu with the Notes containing provisions similar to
those set forth in this Indenture with respect to offers to purchase or redeem
with the proceeds of sales of assets. The Asset Sale Offer will remain open for
a period of at least 20 Business Days following its commencement and not more
than 30 Business Days, except to the extent that a longer period is required by
applicable law (the "Offer Period"). No later than three Business Days after the
termination of the Offer Period (the "Purchase Date"), the Company will apply
all Excess Proceeds (the "Offer Amount") to the purchase of Notes and such other
pari passu Indebtedness (on a pro rata basis, if applicable) or, if less than
the Offer Amount has been tendered, all Notes and other Indebtedness tendered in
response to the Asset Sale Offer. Payment for any Notes so purchased will be
made in the same manner as interest payments are made.

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

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

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

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

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

<PAGE>

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

          (5) that Holders electing to have a Note purchased pursuant to an
     Asset Sale Offer may elect to have Notes purchased in integral multiples of
     $1,000 only;

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

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

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

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

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

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

     The Company shall pay or cause to be paid the principal of, premium, if
any, and interest and Liquidated Damages, if any, on the Notes on the dates and
in the manner provided in the Notes. Principal, premium, if any, and interest
and Liquidated Damages, if any will be considered paid on the date due if the
Paying Agent, if other than the Company or a Subsidiary thereof, holds as of
10:00 a.m. (Eastern Time) on the due date money deposited by the Company in
immediately available funds and designated for and sufficient to pay all
principal, premium, if any, and interest then due. The Company shall pay all
Liquidated Damages, if any, in the same manner on the dates and in the amounts
set forth in the Registration Rights Agreement.

proceeding under any Bankruptcy Law) on overdue principal at the rate equal to
1% per annum in excess of the then applicable interest rate on the Notes to the
extent lawful; it shall pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue installments of interest and
Liquidated Damages (without regard to any applicable grace period) at the same
rate to the extent lawful.

     Section 4.02 Maintenance of Office or Agency.

     Upon appointment of a Trustee, the Company will maintain in the Borough of
Manhattan, the City of New York, an office or agency (which may be an office of
the Trustee or an affiliate of the Trustee, Registrar or co-registrar) where
Notes may be surrendered for registration of transfer or for exchange and where
notices and demands to or upon the Company in respect of the Notes and this
Indenture may be served. The Company shall give prompt written notice to the
Trustee (if appointed) of the location, and any change in the location, of such
office or agency. If at any time the Company fails to maintain any such required
office or agency or fails to furnish the Trustee (if appointed) with the address
thereof, such presentations, surrenders, notices and demands may be made or
served at the Corporate Trust Office of the Trustee (if a Trustee has been
appointed).

     The Company may also from time to time designate one or more other offices
or agencies where the Notes may be presented or surrendered for any or all such
purposes and may from time to time rescind such designations; provided, however,
that no such designation or rescission will in any manner relieve the Company of
its obligation to maintain an office or agency in the Borough of Manhattan, the
City of New York for such purposes following the appointment of a Trustee. The
Company shall give prompt written notice to the Trustee (if appointed) of any
such designation or rescission and of any change in the location of any such
other office or agency.

          (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

          (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.

Company shall file a copy of all of the information and reports referred to in
clauses (1) and (2) above with the SEC for public availability within the time
periods specified in the SEC's rules and regulations (unless the SEC will not

and prospective investors upon request. In addition, the Company and the
Guarantors have agreed that, for so long as any Notes remain outstanding, they
shall furnish to the Holders and to securities analysts and prospective
investors, upon their request, the information required to be delivered pursuant
to Rule 144A(d)(4) under the Securities Act. The Company will at all times
comply with TIA ss. 314(a).

     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

compliance with any of its covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officers' Certificates).

     Section 4.04 Compliance Certificate.

that such Guarantor is so required under the TIA) shall deliver to the Trustee,
within 120 days after the end of each fiscal year (commencing with the fiscal
year ended December 31, 2004), an Officers' Certificate, one of the signers of
which is the chief executive, chief principal or chief accounting officer,
stating that a review of the activities of the Company and its Subsidiaries
during the preceding fiscal year has been made under the supervision of the
signing Officers with a view to determining whether the Company has kept,
observed, performed and fulfilled its obligations under this Indenture, and
further stating, as to each such Officer signing such certificate, that to the
best of his or her knowledge the Company has kept, observed, performed and
fulfilled each

and every covenant contained in this Indenture and is not in default in the
performance or observance of any of the terms, provisions and conditions of this
Indenture (or, if a Default or Event of Default has occurred, describing all
such Defaults or Events of Default of which he or she may have knowledge and
what action the Company is taking or proposes to take with respect thereto) and

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

     (c) So long as any of the Notes are outstanding, the Company shall deliver
to the Trustee (if appointed) or, if no Trustee is appointed, the Holders,
forthwith upon any Officer becoming aware of any Default or Event of Default, an
Officers' Certificate specifying such Default or Event of Default and what
action the Company is taking or proposes to take with respect thereto.

     The Company shall pay, and shall cause each of its Subsidiaries to pay,

where the failure to effect such payment is not adverse in any material respect
to the Holders of the Notes.

     Section 4.06 Stay, Extension and Usury Laws.

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

Subsidiaries to, directly or indirectly:

          (1) declare or pay any dividend or make any other payment or
     distribution on account of the Company's Equity Interests (including,
     without limitation, any payment in connection with any merger or
     consolidation involving the Company or any of its Restricted Subsidiaries)
     or to the direct or indirect holders of the Company's Equity Interests in

          period (taken as one accounting period) from January 1, 2004 to the

          Restricted Subsidiary into Capital Stock (other than Redeemable Stock)
          of the Company (less the amount of any cash or other property (other
          than such Capital Stock) distributed by the Company or any Restricted

          designated as an Unrestricted Subsidiary.

     (b) So long as no Default has occurred and is continuing or would be caused
thereby (except as to clauses (1) through (4), (6), (9), (10), (11) and (12)
below), the provisions of Section 4.07(a) will not prohibit:

          (1) the payment of any dividend within 60 days after the date of
     declaration of the dividend, if at the date of declaration the dividend
     payment would have complied with the provisions of this Indenture;

          (4) the defeasance, redemption, repurchase or other acquisition of
     subordinated Indebtedness from Net Proceeds to the extent not prohibited
     under Section 4.10 hereof, provided that such purchase or redemption shall
     be excluded from the calculation of the amount available for Restricted
     Payments pursuant to the preceding paragraph;

          (5) the defeasance, redemption, repurchase or other acquisition of
     subordinated Indebtedness or Disqualified Stock of the Company or any

     complied with the provisions under Section 4.14 hereof, including payment
     of the applicable Change of Control Payment;

          (6) the repurchase, redemption or other acquisition or retirement for
     value of any Equity Interests of the Company held by any member of the

market value on the date of the Restricted Payment of the asset(s) or securities
proposed to be transferred or issued by the Company or such Restricted
Subsidiary, as the case may be, pursuant to the Restricted Payment. The fair
market value of any assets or securities that are required to be valued by this
Section 4.07 will be determined by the Board of Directors acting in good faith
whose resolution with respect thereto shall be conclusive. Any payments
hereunder shall be calculated net of amounts for which the Company or any
Restricted Subsidiary is reimbursed under the Stock Purchase Agreement.

     Section 4.08 Dividend and Other Payment Restrictions Affecting
Subsidiaries.

     (a) The Company shall not, and shall not permit any of its Restricted

     amendments, modifications, restatements, renewals, increases, supplements,
     refundings, replacements or refinancings are no more restrictive, taken as
     a whole, with respect to such dividend and other payment restrictions than
     those contained in those agreements on the date of this Indenture;

     Subsidiary that restricts distributions by that Restricted Subsidiary

          (7) Permitted Refinancing Indebtedness, provided that the restrictions
     contained in the agreements governing such Permitted Refinancing

     contained in the agreements governing the Indebtedness being Refinanced;

          (8) Liens securing Indebtedness otherwise permitted to be incurred
     under the provisions of Section 4.12 hereof that limit the right of the

     Section 4.09 Incurrence of Indebtedness and Issuance of Preferred Stock.

     (a) The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee
or otherwise become directly or indirectly liable, contingently or otherwise,
with respect to (collectively, "incur") any Indebtedness (including Acquired
Debt), and the Company will not issue any Disqualified Stock and will not permit
any Restricted Subsidiary that is not a Guarantor to issue any shares of
preferred stock; provided, however, that the Company may incur Indebtedness
(including Acquired Debt) or issue Disqualified Stock, and the Restricted
Subsidiaries may incur Indebtedness or Restricted Subsidiaries that are not
Guarantors may issue preferred stock, if the Fixed Charge Coverage Ratio for the
Company's most recently ended four full fiscal quarters for which financial
statements are available immediately preceding the date on which such additional
Indebtedness is incurred or such Disqualified Stock or preferred stock is issued
would have been at least 2.25 to 1.0, determined on a pro forma basis (including
a pro forma application of the net proceeds therefrom), as if the additional
Indebtedness had been incurred or the preferred stock or Disqualified Stock had
been issued, as the case may be, at the beginning of such four-quarter period.

     (b) The provisions of Section 4.09(a) will not prohibit the incurrence of
any of the following items of Indebtedness (collectively, "Permitted Debt"):

          (1) (a) the incurrence by the Company and any Restricted Subsidiary of
     Indebtedness and letters of credit under the revolving facility component
     of the Credit Facilities in an aggregate principal amount at any one time
     outstanding under this clause (1)(a) (with letters of credit being deemed
     to have a principal amount equal to the maximum potential liability of the
     Company and its Subsidiaries thereunder) not to exceed $250.0 million; and

          (b) the incurrence by the Company and any Restricted Subsidiary of
     Indebtedness under the term loan components of the Credit Facilities in an
     aggregate principal amount at any one time outstanding under this clause
     (1)(b) not to exceed $400.0 million, less the aggregate amount of all Net
     Proceeds of Asset Sales applied by the Company or any of the Restricted
     Subsidiaries to repay the principal of any term Indebtedness under a Credit
     Facility since the date of this Indenture; and

          (c) the incurrence of Indebtedness of the Company or any Restricted
     Subsidiary under one or more receivables financing facilities pursuant to
     which the Company or any Restricted Subsidiary pledges or otherwise borrows
     against its Receivables in an aggregate principal amount which, when taken
     together with all other Indebtedness Incurred pursuant to this clause (c)
     and then outstanding, does not exceed 85% of the consolidated book value of
     the Receivables of the Company and the Restricted Subsidiaries (to the
     extent such Receivables or any other Receivables of the Company or such
     Restricted Subsidiary, as the case may be, are not then being financed
     pursuant to a Qualified Receivables Transaction or as a basis for
     Indebtedness Incurred pursuant to clause (10) of this Section 4.09(b));

                                      -53-
<PAGE>

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

          (3) the incurrence by the Company and the Guarantors of Indebtedness
     represented by the Notes and the related Note Guarantees to be issued on
     the date of this Indenture and the Exchange Notes and the related Note
     Guarantees to be issued pursuant to the Registration Rights Agreement;

          (4) the incurrence by the Company or any of its Subsidiaries of
     Indebtedness represented by Capital Lease Obligations, mortgage financings,
     purchase money obligations or otherwise, in each case, incurred for the
     purpose of financing all or any part of the purchase price or cost of
     construction or improvement of property, plant or equipment used in the
     business of the Company or such Restricted Subsidiary ("Capital Spending")
     and incurred no later than 270 days after the date of such acquisition or
     the date of completion of such construction or improvement, provided that
     the principal amount of any Indebtedness incurred pursuant to this clause
     (4) (other than Permitted Refinancing Indebtedness) at any time during a
     single fiscal year shall not exceed 30% of the total Capital Spending of
     the Company and the Restricted Subsidiaries made during the period of the
     most recently completed four consecutive fiscal quarters prior to the date
     of such incurrence;

          (5) the incurrence by the Company or any of its Restricted
     Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the
     net proceeds of which are used to refund, refinance or replace Indebtedness
     (other than intercompany Indebtedness) that was permitted by this Indenture
     to be incurred under Section 4.09(a) or clause (2), (3), (4), (5), (8), (9)
     or (15) of this Section 4.09(b);

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

     (a) if the Company or any Guarantor is the obligor on such Indebtedness,
such Indebtedness must be (i) unsecured and (ii) if the obligee is neither the
Company nor a Guarantor, expressly subordinated to the prior payment in full in
cash of all Obligations with respect to the Notes (in the case of the Company)
(or the Note Guarantee, in the case of a Guarantor); and

     (b) (i) any subsequent issuance or transfer of Equity Interests that
results in any such Indebtedness being held by a Person other than the Company
or a Restricted Subsidiary of the Company and (ii) any sale or other transfer of
any such Indebtedness to a Person that is not either the Company or a Restricted
Subsidiary of the Company will be deemed, in each case, to constitute an
incurrence of such Indebtedness by the Company or such Restricted Subsidiary, as
the case may be, that was not permitted by this clause (6);

          (7) the incurrence by the Company or any of its Restricted
     Subsidiaries of Hedging Obligations that are incurred for the purpose of
     hedging (i) interest rate risk or

                                      -54-
<PAGE>

     the impact of interest rate fluctuations on the Company or any of the
     Restricted Subsidiaries and (ii) in the case of currency or commodity
     protection agreements, against currency exchange rate or commodity price
     fluctuations in the ordinary course of the Company and the Restricted
     Subsidiaries' respective businesses and, in the case of both (i) and (ii),
     not for purposes of speculation;

          (8) the guarantee by the Company or any of the Guarantors of
     Indebtedness of the Company or a Restricted Subsidiary that was permitted
     to be incurred by another provision of this Section 4.09;

          (9) the accrual of interest, the accretion or amortization of original
     issue discount, the payment of interest on any Indebtedness in the form of
     additional Indebtedness with the same terms, and the payment of dividends
     on Disqualified Stock in the form of additional shares of similar
     Disqualified Stock shall not be deemed to be an incurrence of Indebtedness
     or an issuance of Disqualified Stock for purposes of this Section 4.09;
     provided, in each such case, that the amount thereof is included in Fixed
     Charges of the Company as accrued;

          (10) Indebtedness of Foreign Subsidiaries incurred for working capital
     purposes if, at the time of incurrence of such Indebtedness, and after
     giving effect thereto, the aggregate principal amount of all Indebtedness
     of the Foreign Subsidiaries incurred pursuant to this clause (10) and then
     outstanding does not exceed the amount equal to the sum of (x) 80% the
     consolidated book value of the accounts receivable of the Foreign
     Subsidiaries and (y) 60% the consolidated book value of the inventories of
     the Foreign Subsidiaries;

          (11) Indebtedness incurred in respect of (a) workers' compensation
     claims, self-insurance obligations, bankers' acceptances, performance,

     respect of performance bonds or similar obligations of the Company or any
     of the Restricted Subsidiaries for or in connection with pledges, deposits
     or payments made or given in the ordinary course of business and not for
     money borrowed in connection with or to secure statutory, regulatory or
     similar obligations, including obligations under health, safety or
     environmental obligations, and (c) arising from guarantees to suppliers,
     lessors, licensees, contractors, franchises or customers of obligations
     incurred in the ordinary course of business and not for money borrowed;

          (12) Indebtedness arising from agreements of the Company or a
     Restricted Subsidiary providing for indemnification, adjustment of purchase
     price or similar obligations, in each case, incurred or assumed in
     connection with the disposition of any business, assets or Capital Stock of
     a Restricted Subsidiary, provided that the maximum aggregate liability in
     respect of all such Indebtedness shall at no time exceed the gross proceeds
     actually received by the Company and the Restricted Subsidiaries in
     connection with such disposition;

          (13) Indebtedness arising from the honoring by a bank or other
     financial institution of a check, draft or similar instrument (except in
     the case of daylight overdrafts)

                                      -55-
<PAGE>

     drawn against insufficient funds in the ordinary course of business,
     provided, however, that such Indebtedness is extinguished within five
     Business Days of incurrence;

          (14) the incurrence by a Receivables Subsidiary of Indebtedness in a
     Qualified Receivables Transaction that is without recourse to the Company
     or to any other Subsidiary of the Company or their assets (other than such
     Receivables Subsidiary and its assets and, as to the Company or any
     Subsidiary of the Company, other than pursuant to representations,
     warranties, covenants and indemnities customary for such transactions) and
     is not guaranteed by any such Person;

          (15) the issuance and sale of preferred stock (a) by a Foreign
     Subsidiary in lieu of the issuance of non-voting common stock if (i) the
     laws of the jurisdiction of incorporation of such Subsidiary precludes the
     issuance of non-voting common stock and (ii) the preferential rights
     afforded to the holders of such preferred stock are limited to those
     customarily provided for in such jurisdiction in respect of the issuance of
     non-voting stock, (b) by a Restricted Subsidiary which is a joint venture
     with a third party which is not an Affiliate of the Company or a Restricted
     Subsidiary, and (c) by a Restricted Subsidiary pursuant to obligations with
     respect to the issuance or sale of Preferred Stock which exist at the time
     such Person becomes a Restricted Subsidiary and which were not created in
     connection with or in contemplation of such Person becoming a Restricted
     Subsidiary; and

          (16) the incurrence by the Company or any of the Restricted
     Subsidiaries of additional Indebtedness in an aggregate principal amount
     (or accreted value, as applicable) at any time outstanding, including all
     Permitted Refinancing Indebtedness, incurred to refund, refinance or
     replace any Indebtedness incurred pursuant to this clause (16), not to
     exceed $50.0 million.

     For purposes of determining compliance with this Section 4.09, in the event
that an item of proposed Indebtedness meets the criteria of more than one of the
categories of Permitted Debt described in clauses (1) through (16) above, or is
entitled to be incurred pursuant to Section 4.09(a), the Company will be
permitted to classify such item of Indebtedness on the date of its incurrence,
or later reclassify all or a portion of such item of Indebtedness, in any manner
that complies with this Section 4.09. Indebtedness under Credit Facilities
outstanding on the date on which Notes are first issued and authenticated under
this Indenture will be deemed to have been incurred on such date in reliance on
the exception provided by clauses (1) and (2) of the definition of "Permitted
Debt". It is understood that Indebtedness incurred pursuant to clauses (1) and
(2) of the definition of "Permitted Debt" may be refinanced, replaced, renewed
or refunded with any other Indebtedness under clauses (1) or (2), whether or not
in the form of a bank credit facility.

     For purposes of determining compliance with any U.S. dollar-denominated
restriction on the incurrence of Indebtedness, the U.S. dollar-equivalent
principal amount of Indebtedness denominated in a foreign currency shall be
calculated based on the relevant currency exchange rate in effect on the date
such Indebtedness was incurred, in the case of term Indebtedness, or first
committed, in the case of revolving credit Indebtedness; provided that if such
Indebtedness is incurred to Refinance other Indebtedness denominated in a
foreign currency, and such Refinanc-

                                      -56-
<PAGE>

ing would cause the applicable U.S. dollar-denominated restriction to be
exceeded if calculated at the relevant currency exchange rate in effect on the
date of such Refinancing, such U.S. dollar-denominated restriction shall be
deemed not to have been exceeded so long as the principal amount of such
Refinancing Indebtedness does not exceed the principal amount of such
Indebtedness being Refinanced. Notwithstanding any other provision of this
covenant, the maximum amount of Indebtedness that the Company may incur pursuant
to this covenant shall not be deemed to be exceeded solely as a result of
fluctuations in the exchange rate of currencies. The principal amount of any
Indebtedness incurred to Refinance other Indebtedness, if incurred in a
different currency from the Indebtedness being Refinanced, shall be calculated
based on the currency exchange rate applicable to the currencies in which such
Refinancing Indebtedness is denominated that is in effect on the date of such
Refinancing.

     Section 4.10 Asset Sales.

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

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

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

          (3) either (a) at least 75% of the consideration received in the Asset
     Sale by the Company or such Restricted Subsidiary (other than the sale of
     equity securities of TriMas owned by the Company on the date of this
     Indenture) is in the form of cash or (b) the aggregate non-cash
     consideration for all Asset Sales not meeting the criteria set forth in the
     preceding clause (a) does not exceed a fair market value in excess of $20.0
     million. For purposes of this provision, each of the following shall be
     deemed to be cash:

               (A) any liabilities, as shown on the Company's or such Restricted
          Subsidiary's most recent consolidated balance sheet, of the Company or
          any Restricted Subsidiary (other than contingent liabilities and
          liabilities that are by their terms subordinated to the Notes or any
          Note Guarantee) that are assumed by the transferee of any such assets
          pursuant to a customary novation agreement that releases the Company
          or such Restricted Subsidiary from further liability; and

               (B) any securities, notes or other obligations received by the
          Company or any such Restricted Subsidiary from such transferee to the
          extent within 60 days, subject to ordinary settlement periods, they
          are converted by the Company or such Restricted Subsidiary into cash.

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

                                      -57-
<PAGE>

          (1) to permanently repay Indebtedness (other than Indebtedness that is
     by its terms subordinated to, or pari passu with, the Notes or any Note
     Guarantee) of the Company or any Restricted Subsidiary, including any
     Obligations under a Credit Facility and, if the Indebtedness repaid is
     revolving credit Indebtedness, to correspondingly reduce commitments with
     respect thereto or to reduce receivables advances and reduce commitments in
     respect of a Receivables Facility;

          (2) to acquire assets of, or a majority of the Voting Stock of, any
     person owning assets used or usable in a business of the Company and the
     Restricted Subsidiary; or

          (3) to make a capital expenditure.

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

     Any Net Proceeds from Asset Sales that are not applied or invested as
provided in the preceding paragraph (other than Net Proceeds from the sale of
the common stock of TriMas after the date of this Indenture) will constitute
"Excess Proceeds." When the aggregate amount of Excess Proceeds exceeds $25.0
million, within five days thereof, the Company will make an Asset Sale Offer to
all Holders of Notes and all holders of other Indebtedness that is pari passu
with the Notes containing provisions similar to those set forth in this
Indenture with respect to offers to purchase or redeem with the proceeds of
sales of assets in accordance with Section 3.09 hereof to purchase the maximum
principal amount of Notes and such other pari passu Indebtedness that may be
purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer
will be equal to 100% of principal amount plus accrued and unpaid interest and
Liquidated Damages, if any, to the date of purchase, and will be payable in
cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer,
the Company may use those Excess Proceeds for any purpose not otherwise
prohibited by this Indenture. If the aggregate principal amount of Notes and
other pari passu Indebtedness tendered into such Asset Sale Offer exceeds the
amount of Excess Proceeds, the Trustee shall select the Notes, or if no Trustee
has been appointed, the Company shall select the Notes, and such other pari
passu Indebtedness to be purchased on a pro rata basis. Upon completion of each
Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.

     The Company shall comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent those laws and regulations are applicable in connection with each
repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the
provisions of any securities laws or regulations conflict with the provisions of
Sections 3.09 or 4.10 of this Indenture, the Company shall comply with the
applicable securities laws and regulations and will not be deemed to have
breached its obligations under those provisions of this Indenture by virtue of
such conflict.

     Section 4.11 Transactions with Affiliates.

     (a) The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise
dispose of any of its properties or assets to, or purchase any property or
assets from, or enter into or make or amend any transaction,

                                      -58-
<PAGE>

contract, agreement, understanding, loan, advance or guarantee with, or for the
benefit of, any Affiliate (each, an "Affiliate Transaction"), unless:

          (1) the Affiliate Transaction is on terms that are not materially less
     favorable, taken as a whole, to the Company or the relevant Restricted
     Subsidiary than those that would have been obtained at the time in a
     comparable transaction by the Company or such Restricted Subsidiary with an
     unaffiliated Person; and

          (2) the Company delivers to the Trustee:

               (A) except when the opinion referred to in the following clause
          (b) is delivered, with respect to any Affiliate Transaction or series
          of related Affiliate Transactions involving aggregate consideration in
          excess of $5.0 million, a resolution of the Board of Directors set
          forth in an Officers' Certificate certifying that such Affiliate
          Transaction complies with Section 4.11(a) and that such Affiliate
          Transaction has been approved by a majority of the disinterested
          members of the Board of Directors; and

               (B) with respect to any Affiliate Transaction or series of
          related Affiliate Transactions involving aggregate consideration in
          excess of $25.0 million, an opinion as to the fairness to the Company
          of such Affiliate Transaction from a financial point of view issued by
          an accounting, appraisal or investment banking firm of national
          standing.

     (b) The following items will not be deemed to be Affiliate Transactions
and, therefore, will not be subject to the provisions of Section 4.11(a):

          (1) loans or advances to employees, indemnification agreements with
     and the payment of fees and indemnities to directors, officers and
     full-time employees of the Company and the Restricted Subsidiaries and
     employment, non-competition or confidentiality agreements entered into with
     any such person in the ordinary course of business;

          (2) any issuance of securities, or other payments, awards or grants in
     cash, securities or otherwise pursuant to, or the funding of, employment,
     compensation or indemnification arrangements, stock options and stock
     ownership plans in the ordinary course of business to or with officers,
     directors or employees of the Company and the Restricted Subsidiaries, or
     approved by the Board of Directors;

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

          (4) transactions with a Person that is an Affiliate of the Company
     solely because the Company owns an Equity Interest in, or controls, such
     Person;

          (5) transactions pursuant to agreements existing on the date of this
     Indenture, including, without limitation, the Stock Purchase Agreement, the
     Shareholders Agreement, the TriMas Shareholders Agreement and the TriMas
     Corporate Services Agreement, and, in each case, any amendment or
     supplement thereto that, taken in its entirety,

                                      -59-
<PAGE>

     is no less favorable to the Company than such agreement as in effect on the
     date of this Indenture;

          (6) sales of Equity Interests (other than Disqualified Stock) of the
     Company to Affiliates of the Company or the receipt of capital
     contributions by the Company;

          (7) payment of certain fees under the Advisory Agreement;

          (8) transactions (in connection with a Qualified Receivables
     Transaction) between or among the Company and/or its Restricted
     Subsidiaries or transactions between a Receivables Subsidiary and any
     Person in which the Receivables Subsidiary has an Investment;

          (9) any management, service, purchase, lease, supply or similar
     agreement entered into in the ordinary course of the Company's business
     between the Company or any Restricted Subsidiary and any Unrestricted
     Subsidiary or any Affiliate, so long as the Company determines in good
     faith (which determination shall be conclusive) that any such agreement is
     on terms no less favorable to the Company or such Restricted Subsidiary
     than those that could be obtained in a comparable arm's-length transaction
     with an entity that is not an Affiliate; and

          (10) Restricted Payments and Permitted Investments that are permitted
     by Section 4.07 hereof.

     Section 4.12 Liens.

     The Company shall not and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly, create, incur, assume or otherwise
cause or suffer to exist or become effective any Lien of any kind securing
Indebtedness (other than Permitted Liens) upon any of their property or assets,
now owned or hereafter acquired to secure any Indebtedness without making, or
causing such Subsidiary to make, effective provision for securing the Notes or,
in respect of Liens on any Guarantor's property or assets, any Guarantee of such
Guarantor, (x) equally and ratably with such Indebtedness as to such property or
assets for so long as such Indebtedness will be so secured or (y) in the event
such Indebtedness is subordinated Indebtedness, prior to such Indebtedness as to
such property or assets for so long as such Indebtedness will be so secured.

     Section 4.13 Corporate Existence.

     Subject to Article 5 hereof, the Company shall do or cause to be done all
things necessary to preserve and keep in full force and effect:

          (1) its corporate existence, and the corporate, partnership or other
     existence of each of its Subsidiaries, in accordance with the respective
     organizational documents (as the same may be amended from time to time) of
     the Company or any such Subsidiary; and

          (2) the rights (charter and statutory), licenses and franchises of the
     Company and its Subsidiaries;

                                      -60-
<PAGE>

provided, however, that the Company shall not be required to preserve any such
right, license or franchise, or the corporate, partnership or other existence of
any of its Subsidiaries, if the Board of Directors shall determine that the
preservation thereof is no longer desirable in the conduct of the business of
the Company and its Subsidiaries, taken as a whole, and that the loss thereof is
not adverse in any material respect to the Holders of the Notes.

     Section 4.14 Offer to Repurchase upon Change of Control.

     (a) Upon the occurrence of a Change of Control, the Company shall make an
offer (a "Change of Control Offer") to each Holder to repurchase all or any part
(equal to $1,000 or an integral multiple of $1,000) of each Holder's Notes at a
purchase price equal to 101% of the aggregate principal amount thereof plus
accrued and unpaid interest and Liquidated Damages on the Notes repurchased, if
any, to the date of purchase (the "Change of Control Payment"). Within 15 days
following any Change of Control, the Company shall mail a notice to each Holder
describing the transaction or transactions that constitute the Change of Control
and stating:

          (1) that the Change of Control Offer is being made pursuant to this
     Section 4.14 and that all Notes tendered will be accepted for payment;

          (2) the purchase price and the purchase date, which shall be no later
     than 30 Business Days from the date such notice is mailed (the "Change of
     Control Payment Date");

          (3) that any Note not tendered will continue to accrue interest;

          (4) that, unless the Company defaults in the payment of the Change of
     Control Payment, all Notes accepted for payment pursuant to the Change of
     Control Offer will cease to accrue interest after the Change of Control
     Payment Date;

          (5) that Holders electing to have any Notes purchased pursuant to a
     Change of Control Offer will be required to surrender the Notes, with the
     form entitled "Option of Holder to Elect Purchase" on the reverse of the
     Notes completed, to the Paying Agent at the address specified in the notice
     prior to the close of business on the third Business Day preceding the
     Change of Control Payment Date;

          (6) that Holders will be entitled to withdraw their election if the
     Paying Agent receives, not later than the close of business on the second
     Business Day preceding the Change of Control Payment Date, a telegram,
     telex, facsimile transmission or letter setting forth the name of the
     Holder, the principal amount of Notes delivered for purchase, and a
     statement that such Holder is withdrawing his election to have the Notes
     purchased; and

          (7) that Holders whose Notes are being purchased only in part will be
     issued new Notes equal in principal amount to the unpurchased portion of
     the Notes surrendered, which unpurchased portion must be equal to $1,000 in
     principal amount or an integral multiple thereof.

                                      -61-
<PAGE>

     The Company shall comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent those laws and regulations are applicable in connection with the
repurchase of the Notes as a result of a Change of Control. To the extent that
the provisions of any securities laws or regulations conflict with the
provisions of Section 3.09 or this Section 4.14, the Company will comply with
the applicable securities laws and regulations and will not be deemed to have
breached its obligations under Section 3.09 or this Section 4.14 by virtue of
such conflict.

     (b) On the Change of Control Payment Date, the Company will, to the extent
lawful:

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

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

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

     The Paying Agent will promptly mail to each Holder of Notes properly
tendered the Change of Control Payment for such Notes, and the Trustee will
promptly authenticate and mail (or cause to be transferred by book entry) to
each Holder a new Note equal in principal amount to any unpurchased portion of
the Notes surrendered, if any; provided that each new Note will be in a
principal amount of $1,000 or an integral multiple thereof. The Company will
publicly announce the results of the Change of Control Offer on or as soon as
practicable after the Change of Control Payment Date.

     Prior to complying with any of the provisions of this Section 4.14, but in
any event within 90 days following a Change of Control, the Company will either
repay all outstanding Senior Debt or obtain the requisite consents, if any,
under all agreements governing outstanding Senior Debt to permit the repurchase
of notes required by this Section 4.14.

     (c) Notwithstanding anything to the contrary in this Section 4.14, the
Company will not be required to make a Change of Control Offer upon a Change of
Control if a third party makes the Change of Control Offer in the manner, at the
times and otherwise in compliance with the requirements set forth in this
Section 4.14 and Section 3.09 hereof and purchases all Notes validly tendered
and not withdrawn under the Change of Control Offer. Alternatively, the Company
may assign all or part of its obligations to purchase all Notes validly tendered
and not properly withdrawn under a Change of Control Offer to a third party. In
the event of such an assignment, the Company shall be released from its
obligations to purchase the Notes as to which the assignment relates subject to
the third party purchasing such Notes. A Change of Control Offer may be made in
advance of a Change of Control, and conditioned upon such Change of Control if a
definitive agreement is in place for the Change of Control at the time of making
of the Change of Control Offer. Notes repurchased by the Company pursuant to a
Change of Control Offer will have the status of Notes issued but not outstanding
or will be retired and canceled, at

                                      -62-
<PAGE>

the option of the Company. Notes purchased by a third party upon assignment will
have the status of Note issued and outstanding.

     Section 4.15 Anti-Layering.

     The Company shall not incur, create, issue, assume, guarantee or otherwise
become liable for any Indebtedness that is subordinate or junior in right of
payment to any Senior Debt of the Company and senior in any respect in right of
payment to the Notes. No Guarantor shall incur, create, issue, assume, guarantee
or otherwise become liable for any Indebtedness that is subordinate or junior in
right of payment to the Senior Debt of such Guarantor and senior in any respect
in right of payment to such Guarantor's Note Guarantee. The foregoing shall not
affect the Company's 11% senior subordinated notes due 2012, outstanding on the
date of this Indenture.

     Section 4.16 Additional Notes Guarantees.

     After the date of original issuance of the Notes, the Company shall cause
each Restricted Subsidiary, other than a Subsidiary which is a Subsidiary
Guarantor, that becomes a guarantor with respect to the obligations of the
Company or a Domestic Restricted Subsidiary under the Credit Agreement to
execute and deliver to the trustee a Guarantee pursuant to which such Guarantor
shall unconditionally Guarantee, on a joint and several basis, the full and
prompt payment of the principal of, premium, if any, and interest on the Notes
on a senior subordinated basis. Each Guarantor is subject to release of its
obligations under a Guarantee pursuant to Section 11.06.

     Section 4.17 Designation of Restricted and Unrestricted Subsidiaries.

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

                                   ARTICLE 5.

                                   SUCCESSORS

     Section 5.01 Merger, Consolidation, or Sale of Assets.

     The Company shall not, directly or indirectly: (1) consolidate or merge
with or into another Person (whether or not the Company is the surviving
corporation), or (2) sell, assign, transfer, convey or otherwise dispose of all
or substantially all of the properties or assets of the Com-

                                      -63-
<PAGE>

pany and its Restricted Subsidiaries taken as a whole, in one or more related
transactions, to another Person; unless:

          (1) either:

               (A) the Company is the surviving corporation; or

               (B) the Person formed by or surviving any such consolidation or
          merger (if other than the Company) or to which such sale, assignment,
          transfer, conveyance or other disposition has been made is a
          corporation organized or existing under the laws of the United States,
          any state of the United States or the District of Columbia;

          (2) the Person formed by or surviving any such consolidation or merger
     (if other than the Company) or the Person to which such sale, assignment,
     transfer, conveyance or other disposition shall have been made assumes all
     the obligations of the Company under the Notes, this Indenture and the
     Registration Rights Agreement pursuant to agreements reasonably
     satisfactory to the Trustee;

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

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

     In addition, the Company shall not, directly or indirectly, lease all or
substantially all of its properties or assets, in one or more related
transactions, to any other Person. This Section 5.01 will not apply to a sale,
assignment, transfer, conveyance or other disposition of assets between or among
the Company and any of the Guarantors.

     Notwithstanding anything in this Indenture, a Restricted Subsidiary may
consolidate with, merge into or convey, lease, sell, assign, transfer or
otherwise dispose of all or part of its properties and assets to the Company or
a Restricted Subsidiary; and the Company may merge with an Affiliate
incorporated solely for the purpose of reincorporating the Company in another
jurisdiction in the United States to realize tax or other benefits.

     Section 5.02 Successor Corporation Substituted.

     Upon any consolidation or merger, or any sale, assignment, transfer, lease,
conveyance or other disposition of all or substantially all of the assets of the
Company in a transaction that is subject to, and that complies with the
provisions of, Section 5.01 hereof, the successor corporation formed by such
consolidation or into or with which the Company is merged or to which such sale,
assignment, transfer, lease, conveyance or other disposition is made shall
succeed to,

                                      -64-
<PAGE>

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

                                   ARTICLE 6.

                              DEFAULTS AND REMEDIES

     Section 6.01 Events of Default.

     Each of the following is an "Event of Default":

          (1) the Company defaults for 30 days in the payment when due of
     interest on, or Liquidated Damages with respect to, the Notes whether or
     not prohibited by the subordination provisions of this Indenture;

          (2) the Company defaults in the payment when due (at maturity, upon
     redemption or otherwise) of the principal of, or premium, if any, on the
     Notes, whether or not prohibited by the subordination provisions of this
     Indenture;

          (3) failure by the Company or any of its Subsidiaries to comply with
     the provisions of Section 4.14 or 5.01 hereof after written notice to the
     Company by the Trustee or the Holders of at least 25% in aggregate
     principal amount of the outstanding Notes;

          (4) failure by the Company or any of its Subsidiaries to comply with
     any of the other agreements in this Indenture continued for 60 days after
     written notice to the Company by the Trustee or the Holders of at least 25%
     in aggregate principal amount of the outstanding Notes;

          (5) default under any mortgage, indenture or instrument under which
     there may be issued or by which there may be secured or evidenced any
     Indebtedness for money borrowed by the Company or any of its Subsidiaries
     (or the payment of which is guaranteed by the Company or any of its
     Subsidiaries), whether such Indebtedness or guarantee now exists, or is
     created after the date of this Indenture, if that default:

               (A) is caused by a failure to pay principal of such Indebtedness
          at the final maturity thereof (a "Payment Default"); or

               (B) results in the acceleration of such Indebtedness prior to its
          express maturity, and, in each case, the principal amount of any such
          Indebtedness, together with the principal amount of any other such
          Indebtedness under which there has been a Payment Default or the
          maturity of which has been so accelerated, aggregates $20.0 million or
          more;

                                      -65-
<PAGE>

          (6) failure by the Company or any of its Restricted Subsidiaries to
     pay final judgments aggregating in excess of $20.0 million (net of any
     insurance proceeds available to pay such judgment), which judgments are not
     paid, discharged or stayed for a period of 60 days;

          (7) except as permitted by this Indenture, any Note Guarantee shall be
     held in any judicial proceeding to be unenforceable or invalid or shall
     cease for any reason to be in full force and effect or any Guarantor, or
     any Person acting on behalf of any Guarantor, shall deny or disaffirm its
     obligations under its Note Guarantee;

     Section 6.02 Acceleration.

     In the case of an Event of Default specified in clause (8) or (9) of
Section 6.01 hereof, with respect to the Company, all outstanding Notes will
become due and payable immediately without further action or notice. If any
other Event of Default occurs and is continuing, the Trustee or the Holders of
at least 25% in principal amount of the then outstanding Notes may declare all
the Notes to be due and payable immediately by giving notice in writing to the
Company and the Trustee specifying the respective Event of Default (the
"Acceleration Notice") or if there are any amounts outstanding under the Credit
Agreement, it shall become immediately due and payable upon the first to occur
of an acceleration under the Credit Agreement or five Business Days after
receipt by the Company and the administrative agent under the Credit Agreement
of such Acceleration Notice (but only if such Event of Default is then
continuing).

     Upon any such declaration, the Notes shall become due and payable
immediately. The Holders of a majority in aggregate principal amount of the then
outstanding Notes by written notice to the Trustee and the Company may on behalf
of all of the Holders rescind an acceleration and its consequences if the
rescission would not conflict with any judgment or decree and if all existing
Events of Default (except nonpayment of principal, interest or premium that has
become due solely because of the acceleration) have been cured or waived.

     In the event of a declaration of acceleration of the Notes because an Event
of Default described in Section 6.01(5) has occurred and is continuing, the
declaration of acceleration of the Notes shall be automatically annulled if the
event of default or payment default triggering such Event of Default pursuant to
clause (5) shall be remedied or cured by the Company or a Restricted Subsidiary
or waived by the holders of the relevant Indebtedness within 60 days after the
declaration of acceleration with respect thereto and if (a) the annulment of the
acceleration of the Notes would not conflict with any judgment or decree of a
court of competent jurisdiction and (b) all existing Events of Default, except
nonpayment of principal, premium or interest on the Notes that became due solely
because of the acceleration of the Notes, have been cured or waived.

     Section 6.03 Other Remedies.

     If an Event of Default occurs and is continuing, the Trustee or, if no
Trustee has been appointed, the Holders may pursue any available remedy to
collect the payment of principal, premium and Liquidated Damages, if any, and
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 of a Note in exercising any right or remedy
accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. All remedies are
cumulative to the extent permitted by law.

     Section 6.04 Waiver of Past Defaults.

     Holders of not less than a majority in aggregate principal amount of the
then outstanding Notes by notice to the Trustee or, if no Trustee has been
appointed, to the Company, may on be-

                                      -67-
<PAGE>

half of the Holders of all of the Notes waive an existing Default or Event of
Default and its consequences hereunder, except a continuing Default or Event of
Default in the payment of the principal of, premium and Liquidated Damages, if
any, or interest on, the Notes (including in connection with an offer to
purchase); provided, however, that the Holders of a majority in aggregate
principal amount of the then outstanding Notes may rescind an acceleration and
its consequences, including any related payment default that resulted from such
acceleration. Upon any such waiver, such Default shall cease to exist, and any
Event of Default arising therefrom shall be deemed to have been cured for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other Default or impair any right consequent thereon.

     Section 6.05 Control by Majority.

     Holders of a majority in principal amount of the then outstanding Notes may
direct the time, method and place of conducting any proceeding for exercising
any remedy available to the Trustee or exercising any trust or power conferred
on it. However, the Trustee may refuse to follow any direction that conflicts
with law or this Indenture that the Trustee determines may be unduly prejudicial
to the rights of other Holders of Notes or that may involve the Trustee in
personal liability. In the absence of a Trustee, only a majority in principal
amount of the then outstanding Notes are required to take any action relating to
remedies.

     Section 6.06 Limitation on Suits.

     If a Trustee has been appointed, a Holder of a Note may pursue a remedy
with respect to this Indenture or the Notes only if:

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

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

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

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

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

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

     Section 6.07 Rights of Holders of Notes to Receive Payment.

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

     Section 6.08 Collection Suit by Trustee.

     If an Event of Default specified in Section 6.01(1) or (2) occurs and is
continuing, the Trustee is authorized to recover judgment in its own name and as
trustee of an express trust against the Company for the whole amount of
principal of, premium and Liquidated Damages, if any, and interest remaining
unpaid on the Notes and interest on overdue principal and, to the extent lawful,
interest and such further amount as shall be sufficient to cover the costs and
expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel.

     Section 6.09 Trustee May File Proofs of Claim.

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

     Section 6.10 Priorities.

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

                                      -69-
<PAGE>

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

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

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

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

     Section 6.11 Undertaking for Costs.

     In any suit for the enforcement of any right or remedy under this Indenture
or in any suit against the Trustee for any action taken or omitted by it as a
Trustee, a court in its discretion may require the filing by any party litigant
in the suit of an undertaking to pay the costs of the suit, and the court in its
discretion may assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in the suit, having due regard to the merits and good
faith of the claims or defenses made by the party litigant. This Section 6.11
does not apply to a suit by the Trustee, a suit by a Holder of a Note pursuant
to Section 6.07 hereof, or a suit by Holders of more than 10% in principal
amount of the then outstanding Notes.

                                   ARTICLE 7.

                                     TRUSTEE

     Section 7.01 Appointment of Trustee; Duties of Trustee.

     (a) As required by the Registration Rights Agreement, or as otherwise
desired by the Company, an institution that would be eligible to serve as a
trustee under Section 7.10 shall be appointed to serve as Trustee hereunder.
Such appointment shall be evidenced by a supplemental indenture hereto. Any
change or modification to this Indenture required to reflect the appointment of
a Trustee on terms to which that Trustee is accustomed may be reflected in such
supplemental indenture. Such supplemental indenture shall not make any change
affecting the rights of Holders that would require the consent of any Holder and
need only be signed by the institution accepting the appointment to serve as
Trustee, the Company and the Guarantors; provided that the provisions of such
supplemental indenture shall not otherwise require the consent of the Holder
under this Indenture. Until such time as a Trustee is appointed to act
hereunder, provisions hereof referring to a Trustee shall be interpreted as
follows, unless expressly otherwise provided or the context suggests otherwise:

          (i) In the case of provisions relating to the services provided by the
     Trustee to act for the Company, subject to clause (ii) below, such as those
     associated with

                                      -70-
<PAGE>

     ministerial acts, providing notices and making mailings or certain
     information available to Holders, the Company shall be entitled and
     required to act in its stead. (ii) In the case of provisions relating to
     the exercise of rights and remedies by Holders, including, without
     limitation, the provisions of Article 6, Holders of a majority in principal
     amount of outstanding Notes shall be entitled to exercise such rights and
     remedies.

          (iii) This Article 7 (other than this Section 7.01(a)) shall have no
     effect prior to the appointment of the Trustee.

          (iv) In cases of provisions requiring that the Trustee be satisfied
     with a certificate or another document (such as, by way of example,
     5.01(2)), if a similar provision exists in the Company's currently
     outstanding indentures and the purpose of the provision is identical to the
     one in question, such provision shall be deemed to have been satisfied if
     the trustee under the other indentures is satisfied therewith. In cases of
     provisions containing a delivery requirement to the Trustee, such
     requirement may be satisfied by providing the Initial Holder with a notice
     stating that such document is available upon request.

          (v) All amendments, supplements, modifications and waivers may be
     executed in accordance with the provisions of Article 9, without the
     necessity of the signature or consent of the Trustee; provided that notice
     of each action is given to Holders, together with copies of any Opinions of
     Counsel addressed to the Company or Officers' Certificates required by
     Article 9.

          (vi) Legal Defeasance and Covenant Defeasance under Article 8 may only
     be exercised after appointing a person eligible to serve as a Trustee to
     act as Trustee for the purpose of the applicable provisions thereof.

          (vii) Any action that may be performed by either or both of the
     Trustee, on the one hand, or a Paying Agent or Registrar, on the other
     hand, shall be performed solely by such other person.

          (viii) A Payment Blockage Notice under Article 10 shall be effective
     if delivered by the holders of any Designated Senior Debt to the Company or
     one of its Restricted Subsidiaries, even in the absence of a Trustee or
     notice to Holders. Under Section 10.13, the Representatives need not wait
     30 days to act in lieu of a Trustee. Any notice permitted to be given by a
     creditor of the Company or a Guarantor to the Trustee shall be effective if
     delivered to the Company and the Company shall thereafter be obligated to
     transmit such information to Holders.

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

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

          (1) the duties of the Trustee will be determined solely by the express
     provisions of this Indenture and the Trustee need perform only those duties
     that are specifi-

                                      -71-
<PAGE>

     cally set forth in this Indenture and no others, and no implied covenants
     or obligations shall be read into this Indenture against the Trustee; and

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

     (d) 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:

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

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

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

     (e) Whether or not therein expressly so provided, every provision of this
Indenture that in any way relates to the Trustee is subject to paragraphs (b),
(c) and (d) of this Section 7.01.

     (f) No provision of this Indenture will 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 its rights and powers under this Indenture at the
request of any Holders, unless such Holder has offered to the Trustee security
and indemnity satisfactory to it against any loss, liability or expense.

     (g) The Trustee will not be liable for interest on any money received by it
except as the Trustee may agree in writing with the Company. Money held in trust
by the Trustee need not be segregated from other funds except to the extent
required by law.

     Section 7.02 Rights of Trustee.

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

     (b) Before the Trustee acts or refrains from acting, it may require an
Officers' Certificate or an Opinion of Counsel or both. The Trustee will 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 written advice of such counsel or any Opinion
of Counsel will be full and complete authorization and protection from liability
in respect of any action taken, suffered or omitted by it hereunder in good
faith and in reliance thereon.

                                      -72-
<PAGE>

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

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

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

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

     (g) 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.

     (h) 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.

     (i) The Trustee may request that the Company deliver an Officers'
Certificate setting forth the names of individuals and/or titles of officers
authorized at such time to take specified actions pursuant to this Indenture,
which Officers' Certificate may be signed by any person authorized to sign an
Officers' Certificate, including any person specified as so authorized in any
such certificate previously delivered and not superseded.

     Section 7.03 Individual Rights of Trustee.

     The Trustee in its individual or any other capacity may become the owner or
pledgee of Notes and may otherwise deal with the Company or any Affiliate of the
Company with the same rights it would have if it were not Trustee. However, in
the event that the Trustee acquires any conflicting interest it must eliminate
such conflict within 90 days, apply to the SEC for permission to continue as
trustee or resign. Any Agent may do the same with like rights and duties. The
Trustee is also subject to Sections 7.10 and 7.11 hereof.

     Section 7.04 Trustee's Disclaimer.

     The Trustee will not be responsible for and makes no representation as to
the validity or adequacy of this Indenture or the Notes, it shall not be
accountable for the Company's use of the proceeds from the Notes or any money
paid to the Company or upon the Company's direction under any provision of this
Indenture, it will not be responsible for the use or application of any money
received by any Paying Agent other than the Trustee, and it will not be
responsible for

                                      -73-
<PAGE>

any statement or recital herein or any statement in the Notes or any other
document in connection with the sale of the Notes or pursuant to this Indenture
other than its certificate of authentication.

     Section 7.05 Notice of Defaults.

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

     Section 7.06 Reports by Trustee to Holders of the Notes.

     (a) Within 60 days after each May 15 beginning with the May 15 following
the date of this Indenture, and for so long as Notes remain outstanding, the
Trustee will mail to the Holders of the Notes a brief report dated as of such
reporting date that complies with TIA ss. 313(a) (but if no event described in
TIA ss. 313(a) has occurred within the twelve months preceding the reporting
date, no report need be transmitted). The Trustee also will comply with TIA ss.
313(b)(2). The Trustee will also transmit by mail all reports as required by TIA
ss. 313(c).

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

     Section 7.07 Compensation and Indemnity.

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

     (b) The Company and the Guarantors will indemnify the Trustee and any
predecessor Trustee against any and all losses, liabilities, claims, damages or
expenses, including taxes (other than taxes based upon, measured by or
determined by 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, including the costs and expenses of enforcing this Indenture against
the Company and the Guarantors (including this Section 7.07) and defending
itself against any claim (whether asserted by the Company, the Guarantors or any
Holder or any other Person) or liability in connection with the exercise or
performance of any of its powers or duties hereunder, except to the extent any
such loss, liability or expense may be attributable to its negligence or bad
faith. The Trustee will notify the Company promptly of any claim for which it
may seek indemnity. Failure by the Trustee to so notify the Company will not
relieve the Company or any of the Guarantors of their obligations hereunder. The
Company or such Guarantor will defend the claim and

                                      -74-
<PAGE>

the Trustee will cooperate in the defense. The Trustee may have separate counsel
and the Company will pay the reasonable fees and expenses of such counsel.
Neither the Company nor any Guarantor need pay for any settlement made without
its consent, which consent will not be unreasonably withheld.

     (c) The obligations of the Company and the Guarantors under this Section
7.07 will survive the satisfaction and discharge of this Indenture and the
resignation or removal of the Trustee.

     (d) To secure the Company's payment obligations in this Section 7.07, the
Trustee will 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 will survive the satisfaction and
discharge of this Indenture.

     (e) When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 6.01(8) or (9) hereof occurs, the expenses and the
compensation for the services (including the fees and expenses of its agents and
counsel) are intended to constitute expenses of administration under any
Bankruptcy Law.

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

     Section 7.08 Replacement of Trustee.

     (a) A resignation or removal of the Trustee and appointment of a successor
Trustee will become effective only upon the successor Trustee's acceptance of
appointment as provided in this Section 7.08.

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

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

          (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.

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

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

     (e) If the Trustee, after written request by any Holder who has been a

may petition any court of competent jurisdiction for the removal of the Trustee
and the appointment of a successor Trustee.

     (f) A successor Trustee will deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Thereupon, the
resignation or removal of the retiring Trustee will become effective, and the
successor Trustee will have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee will mail a notice of its succession
to Holders. The retiring Trustee will promptly transfer all property held by it
as Trustee to the successor Trustee, provided all sums owing to the Trustee
hereunder have been paid and subject to the Lien provided for in Section 7.07
hereof. Notwithstanding replacement of the Trustee pursuant to this Section
7.08, the Company's obligations under Section 7.07 hereof will continue for the
benefit of the retiring Trustee.

     Section 7.09 Successor Trustee by Merger, etc.

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

     Section 7.10 Eligibility; Disqualification.

     There will at all times be a Trustee hereunder that is a corporation
organized and doing business under the laws of the United States of America or
of any state thereof that is authorized under such laws to exercise corporate
trustee power, that is subject to supervision or examination by federal or state
authorities and that has a combined capital and surplus of at least $50 million
as set forth in its most recent published annual report of condition.

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

     Section 7.11 Preferential Collection of Claims Against Company.

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

                                   ARTICLE 8.

                    LEGAL DEFEASANCE AND COVENANT DEFEASANCE

     Section 8.01 Option to Effect Legal Defeasance or Covenant Defeasance.

     The Company may, at the option of its Board of Directors evidenced by a
resolution set forth in an Officers' Certificate, at any time, elect to have
either Section 8.02 or 8.03 hereof be applied to all outstanding Notes upon
compliance with the conditions set forth below in this Article 8.

     Section 8.02 Legal Defeasance and Discharge.

     Upon the Company's exercise under Section 8.01 hereof of the option
applicable to this Section 8.02, the Company and each of the Guarantors will,
subject to the satisfaction of the conditions set forth in Section 8.04 hereof,
be deemed to have been discharged from their obligations with respect to all
outstanding Notes (including the Note Guarantees) on the date the conditions set
forth below are satisfied (hereinafter, "Legal Defeasance"). For this purpose,
Legal Defeasance means that the Company and the Guarantors will be deemed to
have paid and discharged the entire Indebtedness represented by the outstanding
Notes (including the Note Guarantees), which will thereafter be deemed to be
"outstanding" only for the purposes of Section 8.05 hereof and the other
Sections of this Indenture referred to in clauses (1) and (2) below, and to have
satisfied all their other obligations under such Notes, the Note Guarantees 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 will survive until otherwise terminated or discharged
hereunder:

          (1) the rights of Holders of outstanding Notes to receive payments in
     respect of the principal of, or interest or premium and Liquidated Damages,
     if any, on such Notes when such payments are due from the trust referred to
     in Section 8.04 hereof;

          (2) the Company's obligations with respect to such Notes under Article
     2 and Section 4.02 hereof;

          (3) the rights, powers, trusts, duties and immunities of the Trustee
     hereunder and the Company's and the Guarantors' obligations in connection
     therewith; and

          (4) this Article 8.

     Subject to compliance with this Article 8, the Company may exercise its
option under this Section 8.02 notwithstanding the prior exercise of its option
under Section 8.03 hereof.

     Section 8.03 Covenant Defeasance.

     Upon the Company's exercise under Section 8.01 hereof of the option
applicable to this Section 8.03, the Company and the Guarantors will, subject to
the satisfaction of the conditions set forth in Section 8.04 hereof, be released
from each of their obligations under the covenants contained in Sections 4.07,
4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.14, 4.15, 4.16 and 4.17 hereof and

                                      -77-
<PAGE>

clause (4) of Section 5.01 hereof with respect to the outstanding Notes on and
after the date the conditions set forth in Section 8.04 hereof are satisfied
(hereinafter, "Covenant Defeasance"), and the Notes will 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 will continue to be deemed "outstanding" for
all other purposes hereunder (it being understood that such Notes will not be
deemed outstanding for accounting purposes). For this purpose, Covenant
Defeasance means that, with respect to the outstanding Notes and Note
Guarantees, the Company and the Guarantors may omit to comply with and will 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 will not constitute a Default or an Event of Default under
Section 6.01 hereof, but, except as specified above, the remainder of this
Indenture and such Notes and Note Guarantees will be unaffected thereby. In
addition, upon the Company's exercise under Section 8.01 hereof of the option
applicable to this Section 8.03 hereof, subject to the satisfaction of the
conditions set forth in Section 8.04 hereof, Sections 6.01(3) through 6.01(5)
hereof will not constitute Events of Default.

     Section 8.04 Conditions to Legal or Covenant Defeasance.

     In order to exercise either Legal Defeasance or Covenant Defeasance under
either Section 8.02 or 8.03 hereof:

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

          (2) in the case of an election under Section 8.02 hereof, the Company
     has delivered to the Trustee an Opinion of Counsel in the United States
     reasonably acceptable to the Trustee confirming that:

               (A) the Company has received from, or there has been published
          by, the Internal Revenue Service a ruling; or

               (B) since the date of this Indenture, there has been a change in
          the applicable federal income tax law,

     in either case to the effect that, and based thereon such Opinion of
     Counsel shall confirm that, the Holders of the outstanding Notes will not
     recognize income, gain or loss for federal income tax purposes as a result
     of such Legal Defeasance and will be subject to federal income tax on the
     same amounts, in the same manner

                                      -78-
<PAGE>

     and at the same times as would have been the case if such Legal Defeasance
     had not occurred;

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

          (4) no Default or Event of Default shall have occurred and be
     continuing on the date of such deposit (other than a Default or Event of
     Default resulting from the borrowing of funds to be applied to such
     deposit);

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

          (6) the Company must deliver to the Trustee an Officers' Certificate
     stating that the deposit was not made by the Company with the intent of
     preferring the Holders of Notes over the other creditors of the Company
     with the intent of defeating, hindering, delaying or defrauding any other
     creditors of the Company or others; and

          (7) the Company must deliver 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.

     In the event that the Company exercises its legal defeasance option or
covenant defeasance option, each of the Guarantors will be released from all of
its obligations with respect to its guarantee. The Company may exercise its
legal defeasance option notwithstanding its prior exercise of the covenant
defeasance option.

     Section 8.05 Deposited Money and Government Securities to Be Held in Trust;
                  Other Miscellaneous Provisions.

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

                                      -79-
<PAGE>

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

     Notwithstanding anything in this Article 8 to the contrary, the Trustee
will deliver or pay to the Company from time to time upon the request of the
Company any money or non-callable Government Securities held by it as provided
in Section 8.04 hereof which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee (which may be the opinion delivered under Section
8.04(1) hereof), are in excess of the amount thereof that would then be required
to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

     Section 8.06 Repayment to Company.

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

     Section 8.07 Reinstatement.

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

                                   ARTICLE 9.

                        AMENDMENT, SUPPLEMENT AND WAIVER

     Section 9.01 Without Consent of Holders of Notes.

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

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

          (2) to provide for uncertificated Notes in addition to or in place of
     certificated Notes or to alter the provisions of Article 2 hereof
     (including the related definitions) in a manner that does not materially
     adversely affect any Holder;

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

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

          (5) to comply with requirements of the SEC in order to effect or
     maintain the qualification of this Indenture under the TIA;

          (6) to allow any Guarantor to execute a supplemental indenture and/or
     a Note Guarantee with respect to the Notes;

          (7) to conform to any future amendment or supplement to the 2002
     Indenture, the 2012 Notes or the related guarantees, unless such conforming
     amendment or supplement to this Indenture would otherwise require the
     consent of each Holder affected under Section 9.02 hereof; or

          (8) to provide for the appointment of a Trustee as contemplated by
     Section 7.01(a).

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

                                      -81-
<PAGE>

     Section 9.02 With Consent of Holders of Notes.

     Except as provided below in this Section 9.02, the Company and the Trustee
may amend or supplement this Indenture (including, without limitation, Section
3.09, 4.10 and 4.14 hereof), the Note Guarantees and the Notes with the consent
of the Holders of at least a majority in principal amount of the Notes then
outstanding voting as a single class (including, without limitation, consents
obtained in connection with a tender offer or exchange offer for, or purchase
of, the Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing
Default or Event of Default (other than a Default or Event of Default in the
payment of the principal of, premium or Liquidated Damages, if any, or interest
on the Notes, except a payment default resulting from an acceleration that has
been rescinded) or compliance with any provision of this Indenture, the Note
Guarantees or the Notes may be waived with the consent of the Holders of a
majority in principal amount of the then outstanding Notes voting as a single
class (including consents obtained in connection with a tender offer or exchange
offer for, or purchase of, the Notes). Section 2.08 hereof shall determine which
Notes are considered to be "outstanding" for purposes of this Section 9.02.

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

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

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

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

          (2) reduce the principal of or change the fixed maturity of any Note
     or alter or waive any of the provisions with respect to the redemption of
     the Notes except as provided above with respect to Sections 3.09, 4.10 and
     4.14 hereof;

                                      -82-
<PAGE>

          (3) reduce the rate of or change the time for payment of interest,
     including default interest, on any Note;

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

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

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

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

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

          (9) waive a redemption payment with respect to any Note (other than a
     payment required by Sections 4.10 and 4.14).

     In addition, any amendment to, or waiver of, the provisions of this
Indenture relating to subordination that adversely affects the rights of the
Holders of the Notes will require the consent of the Holders of at least 75% in
aggregate principal amount of Notes then outstanding.

     Section 9.03 Compliance with Trust Indenture Act.

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

     Section 9.04 Revocation and Effect of Consents.

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

     Section 9.05 Notation on or Exchange of Notes.

     The Trustee may place an appropriate notation about an amendment,
supplement or waiver on any Note thereafter authenticated. The Company in
exchange for all Notes may issue

                                      -83-
<PAGE>

and the Trustee shall, upon receipt of an Authentication Order, authenticate new
Notes that reflect the amendment, supplement or waiver.

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

     Section 9.06 Trustee to Sign Amendment, etc.

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

                                   ARTICLE 10.

                                  SUBORDINATION

     Section 10.01 Agreement to Subordinate.

     The Company agrees, and each Holder by accepting a Note agrees, that the
Indebtedness evidenced by the Notes is subordinated in right of payment, to the
extent and in the manner provided in this Article 10, to the prior payment in
full of all Senior Debt (whether outstanding on the date hereof or hereafter
created, incurred, assumed or guaranteed), and that the subordination is for the
benefit of the holders of Senior Debt. For the avoidance of doubt, the 2012
Notes are parri passu in right of payment to the Indebtedness evidenced by the
Notes.

     Section 10.02 Certain Definitions.

     "Designated Senior Debt" means:

          (1) any Indebtedness outstanding under the Credit Facilities and all
     Hedging Obligations with respect thereto; and

          (2) after payment in full of all Obligations under the Credit
     Facilities, any other Senior Debt permitted under this Indenture the
     principal amount of which is $25.0 million or more and that has been
     designated by the Company as "Designated Senior Debt."

     "Permitted Junior Securities" means:

          (1) Equity Interests in the Company or any Guarantor; or

          (2) debt securities that are subordinated to all Senior Debt and any
     debt securities issued in exchange for Senior Debt to substantially the
     same extent as, or to a

                                      -84-
<PAGE>

     greater extent than, the Notes and the Note Guarantees are subordinated to
     Senior Debt under this Indenture.

     "Representative" means the indenture trustee or other trustee, agent or
representative for any Senior Debt.

     "Senior Debt" means:

          (1) all Indebtedness of the Company or any Guarantor outstanding under
     Credit Facilities and all Hedging Obligations with respect thereto;

          (2) any other Indebtedness of the Company or any Guarantor permitted
     to be incurred under the terms of this Indenture, unless the instrument
     under which such Indebtedness is incurred expressly provides that it is on
     a parity with or subordinated in right of payment to the Notes or any Note
     Guarantee; and

          (3) all Obligations with respect to the items listed in the preceding
     clauses (1) and (2).

     Notwithstanding anything to the contrary in the foregoing, Senior Debt will
not include:

          (1) any liability for federal, state, local or other taxes owed or
     owing by the Company;

          (2) any intercompany Indebtedness of the Company or any of its
     Subsidiaries to the Company or any of its Affiliates;

          (3) any trade payables; or

          (4) the portion of any Indebtedness that is incurred in violation of
     this Indenture; provided that such Indebtedness shall be deemed not to have
     been incurred in violation of this Indenture for purposes of this clause
     (4) if such Indebtedness consists of Indebtedness under any Credit Facility
     and holders of such Indebtedness or their Representative (i) had no actual
     knowledge at the time of the incurrence that the incurrence of such
     Indebtedness violated this Indenture and (ii) shall have received an
     Officers' Certificate to the effect that the incurrence of such
     Indebtedness does not violate the provisions of this Indenture.

     Section 10.03 Liquidation; Dissolution; Bankruptcy.

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

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

                                      -85-
<PAGE>

     the Holders of Notes will be entitled to receive any payment with respect
     to the Notes (except that Holders of Notes may receive and retain Permitted
     Junior Securities and payments made from any defeasance trust created
     pursuant to Section 8.01 hereof); and

          (2) until all Obligations with respect to Senior Debt (as provided in
     clause (1) above) are paid in full, any distribution to which Holders would
     be entitled but for this Article 10 will be made to holders of Senior Debt
     (except that Holders of Notes may receive and retain Permitted Junior
     Securities and payments made from any defeasance trust created pursuant to
     Section 8.01 hereof), as their interests may appear.

     Section 10.04 Default on Designated Senior Debt.

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

          (1) payment default on Designated Senior Debt occurs and is continuing
     beyond any applicable grace period in the agreement, indenture or other
     document governing such Designated Senior Debt; or

          (2) any other default occurs and is continuing on any series of
     Designated Senior Debt that permits holders of that series of Designated
     Senior Debt to accelerate its maturity and the Trustee receives a notice of
     such default (a "Payment Blockage Notice") from the Company or the holders
     of any Designated Senior Debt. If the Trustee or, if no Trustee has been
     appointed, the Company receives any such Payment Blockage Notice, no
     subsequent Payment Blockage Notice will be effective for purposes of this
     Section unless and until (A) at least 360 days have elapsed since the
     effectiveness of the immediately prior Payment Blockage Notice and (B) all
     scheduled payments of principal, premium and Liquidated Damages, if any,
     and interest on the Notes that have come due have been paid in full in
     cash.

     No nonpayment default that existed or was continuing on the date of
delivery of any Payment Blockage Notice to the Trustee or, if no Trustee has
been appointed, the Company may be, or may be made, the basis for a subsequent
Payment Blockage Notice unless such default has have been waived for a period of
not less than 90 days.

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

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

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

                                      -86-
<PAGE>

if this Article 10 otherwise permits the payment, distribution or acquisition at
the time of such payment or acquisition.

     Section 10.05 Acceleration of Notes.

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

     Section 10.06 When Distribution Must Be Paid Over.

     In the event that the Trustee or any Holder receives any payment of any
Obligations with respect to the Notes (other than Permitted Junior Securities
and payments made from any defeasance trust created pursuant to Section 8.01
hereof) at a time when the Trustee or such Holder, as applicable, has actual
knowledge that such payment is prohibited by Section 10.04 hereof, such payment
will be held by the Trustee or such Holder, in trust for the benefit of, and
will be paid forthwith over and delivered, upon written request, to, the holders
of Senior Debt as their interests may appear or their Representative under the
agreement, indenture or other document (if any) pursuant to which Senior Debt
may have been issued, as their respective interests may appear, for application
to the payment of all Obligations with respect to Senior Debt remaining unpaid
to the extent necessary to pay such Obligations in full in accordance with their
terms, after giving effect to any concurrent payment or distribution to or for
the holders of Senior Debt.

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

     Section 10.07 Notice by Company.

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

     Section 10.08 Subrogation.

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

                                      -87-
<PAGE>

     Section 10.09 Relative Rights.

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

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

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

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

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

     Section 10.10 Subordination May Not Be Impaired by Company.

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

     Section 10.11 Distribution or Notice to Representative.

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

     Upon any payment or distribution of assets of the Company referred to in
this Article 10, the Trustee and the Holders of Notes will be entitled to rely
upon any order or decree made by any court of competent jurisdiction or upon any
certificate of such Representative or of the liquidating trustee or agent or
other Person making any distribution to the Trustee or to the Holders of Notes
for the purpose of ascertaining the Persons entitled to participate in such
distribution, the holders of the Senior Debt and other Indebtedness of the
Company, the amount thereof or payable thereon, the amount or amounts paid or
distributed thereon and all other facts pertinent thereto or to this Article 10.

     Section 10.12 Rights of Trustee and Paying Agent.

     Notwithstanding the provisions of this Article 10 or any other provision of
this Indenture, the Trustee will not be charged with knowledge of the existence
of any facts that would prohibit the making of any payment or distribution by
the Trustee, and the Trustee and the Paying Agent may continue to make payments
on the Notes, unless the Trustee has received at its Corporate Trust Office at
least five Business Days prior to the date of such payment written notice of
facts

                                      -88-
<PAGE>

that would cause the payment of any Obligations with respect to the Notes to
violate this Article 10. Only the Company or a Representative may give the
notice. Nothing in this Article 10 will impair the claims of, or payments to,
the Trustee under or pursuant to Section 7.07 hereof.

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

     Section 10.13 Authorization to Effect Subordination.

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

     Section 10.14 Amendments.

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

                                  ARTICLE 11.

                                 NOTE GUARANTEE

     Section 11.01 Guarantees.

     (a) Subject to this Article 11, each of the Guarantors hereby, jointly and
severally, unconditionally guarantees to each Holder of a Note authenticated and
delivered by the Trustee (if a Trustee has been appointed) and to the Trustee
and its successors and assigns, irrespective of the validity and enforceability
of this Indenture, the Notes or the obligations of the Company hereunder or
thereunder, that:

          (1) the principal of, premium and Liquidated Damages, if any, and
     interest on the Notes will be promptly paid in full when due, whether at
     maturity, by acceleration, redemption or otherwise, and interest on the
     overdue principal of and interest on the Notes, if any, if lawful, and all
     other obligations of the Company to the Holders or the Trustee hereunder or
     thereunder will be promptly paid in full or performed, all in accordance
     with the terms hereof and thereof; and

          (2) in case of any extension of time of payment or renewal of any
     Notes or any of such other obligations, that same will be promptly paid in
     full when due or performed in accordance with the terms of the extension or
     renewal, whether at stated maturity, by acceleration or otherwise.

     Failing payment when due of any amount so guaranteed or any performance so
guaranteed for whatever reason, the Guarantors will be jointly and severally
obligated to pay the same

                                      -89-
<PAGE>

immediately. Each Guarantor agrees that this is a guarantee of payment and not a
guarantee of collection.

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

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

     (d) Each Guarantor agrees that it will not be entitled to any right of
subrogation in relation to the Holders in respect of any obligations guaranteed
hereby until payment in full of all obligations guaranteed hereby. Each
Guarantor further agrees that, as between the Guarantors, on the one hand, and
the Holders and the Trustee, on the other hand, (1) the maturity of the
obligations guaranteed hereby may be accelerated as provided in Article 6 hereof
for the purposes of this Note Guarantee, notwithstanding any stay, injunction or
other prohibition preventing such acceleration in respect of the obligations
guaranteed hereby, and (2) in the event of any declaration of acceleration of
such obligations as provided in Article 6 hereof, such obligations (whether or
not due and payable) will forthwith become due and payable by the Guarantors for
the purpose of this Note Guarantee. The Guarantors will have the right to seek
contribution from any non-paying Guarantor so long as the exercise of such right
does not impair the rights of the Holders under the Note Guarantee.

     Section 11.02 Subordination of Note Guarantee.

     The Obligations of each Guarantor under its Note Guarantee pursuant to this
Article 11 will be junior and subordinated to the Senior Debt of such Guarantor
on the same basis as the Notes are junior and subordinated to Senior Debt of the
Company. For the purposes of the foregoing sentence, the Trustee and the Holders
will have the right to receive and/or retain payments by any of the Guarantors
only at such times as they may receive and/or retain payments in respect of the
Notes pursuant to this Indenture, including Section 10.01 hereof.

     Section 11.03 Limitation on Guarantor Liability.

     Each Guarantor, and by its acceptance of Notes, each Holder, hereby
confirms that it is the intention of all such parties that the Note Guarantee of
such Guarantor not constitute a fraudulent transfer or conveyance for purposes
of Bankruptcy Law, the Uniform Fraudulent

                                      -90-
<PAGE>

Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or
state law to the extent applicable to any Note Guarantee. To effectuate the
foregoing intention, the Trustee, the Holders and the Guarantors hereby
irrevocably agree that the obligations of such Guarantor will be limited to the
maximum amount that will, after giving effect to such maximum amount and all
other contingent and fixed liabilities of such Guarantor that are relevant under
such laws, and after giving effect to any collections from, rights to receive
contribution from or payments made by or on behalf of any other Guarantor in
respect of the obligations of such other Guarantor under this Article 11, result
in the obligations of such Guarantor under its Note Guarantee not constituting a
fraudulent transfer or conveyance.

     Section 11.04 Execution and Delivery of Note Guarantee.

     To evidence its Note Guarantee set forth in Section 11.01, each Guarantor
hereby agrees that a notation of such Note Guarantee substantially in the form
attached as Exhibit E hereto will be endorsed by an Officer of such Guarantor on
each Note authenticated and delivered by the Trustee (if a Trustee has been
appointed) and that this Indenture will be executed on behalf of such Guarantor
by one of its Officers.

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

     If an Officer whose signature is on this Indenture or on the Note Guarantee
no longer holds that office at the time the Trustee authenticates the Note (if a
Trustee has been appointed), or if a Trustee has not been appointed, following
the Note's issuance, on which a Note Guarantee is endorsed, the Note Guarantee
will be valid nevertheless.

     The delivery of any Note by the Trustee or the Company, after the
authentication thereof hereunder (if a Trustee has been appointed), will
constitute due delivery of the Note Guarantee set forth in this Indenture on
behalf of the Guarantors.

     In the event that the Company creates or acquires any Domestic Subsidiary
after the date of this Indenture that are guarantors or borrowers in respect of
the Credit Agreement, if required by Section 4.16 hereof, the Company will cause
such Domestic Subsidiary to comply with the provisions of Section 4.16 hereof
and this Article 11, to the extent applicable.

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

     Except as otherwise provided in Section 11.06, no Guarantor may sell or
otherwise dispose of all or substantially all of its assets to, or consolidate
with or merge with or into (whether or not such Guarantor is the surviving
Person) another Person, other than the Company or another Guarantor, unless:

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

          (2) either:

                                      -91-
<PAGE>

               (a) subject to Section 11.06 hereof, the Person acquiring the
          property in any such sale or disposition or the Person formed by or
          surviving any such consolidation or merger unconditionally assumes all
          the obligations of that Guarantor, pursuant to a supplemental
          indenture in form and substance reasonably satisfactory to the
          Trustee, under the Notes, this Indenture and the Note Guarantee on the
          terms set forth herein or therein; and

               (b) the Net Proceeds of such sale or other disposition are
          applied in accordance with the applicable provisions of this
          Indenture, including without limitation, Section 4.10 hereof.

     In case of any such consolidation, merger, sale or conveyance and upon the
assumption by the successor Person, by supplemental indenture, executed and
delivered to the Trustee and satisfactory in form to the Trustee, of the Note
Guarantee endorsed upon the Notes and the due and punctual performance of all of
the covenants and conditions of this Indenture to be performed by the Guarantor,
such successor Person will succeed to and be substituted for the Guarantor with
the same effect as if it had been named herein as a Guarantor. Such successor
Person thereupon may cause to be signed any or all of the Note Guarantees to be
endorsed upon all of the Notes issuable hereunder which theretofore shall not
have been signed by the Company and delivered to the Trustee. All the Note
Guarantees so issued will in all respects have the same legal rank and benefit
under this Indenture as the Note Guarantees theretofore and thereafter issued in
accordance with the terms of this Indenture as though all of such Note
Guarantees had been issued at the date of the execution hereof.

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

     Section 11.06 Releases of Guarantees.

     In the event (i) of any sale or other disposition of all or substantially
all of the assets of any Guarantor, by way of merger, consolidation or
otherwise, or a sale or other disposition of all to the Capital Stock of any
Guarantor, in each case to a Person that is not (either before or after giving
effect to such transactions) a Restricted Subsidiary of the Company, (ii) any
Restricted Subsidiary that is a Guarantor is designated as an Unrestricted
Subsidiary or (iii) a release of a Guarantor from its guarantee of, and all
pledges and security interests granted in connection with the Credit Agreement,
then such Guarantor (in the event of a sale or other disposition, by way of
merger, consolidation or otherwise, of all of the capital stock of such
Guarantor or release from the Credit Agreement or designation as an Unrestricted
Subsidiary) or the corporation acquiring the property (in the event of a sale or
other disposition of all or substantially all of the assets of such Guarantor)
will be released and relieved of any obligations under its Note Guarantee;
provided that the Net Proceeds of such sale or other disposition are applied in
accordance with the applicable provisions of this Indenture, including without
limitation Section 4.10 hereof. Upon delivery by the Company to the Trustee of
an Officers' Certificate and an Opinion of Counsel to the effect that such sale
or other disposition was made by the Company in accordance with the

                                      -92-
<PAGE>

provisions of this Indenture, including without limitation Section 4.10 hereof,
the Trustee will execute any documents reasonably required in order to evidence
the release of any Guarantor from its obligations under its Note Guarantee.

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

                                   ARTICLE 12.

                           SATISFACTION AND DISCHARGE

     Section 12.01 Satisfaction and Discharge.

     This Indenture will be discharged and will cease to be of further effect as
to all Notes issued hereunder, when:

     (1) either:

          (a) all Notes that have been authenticated (except lost, stolen or
     destroyed Notes that have been replaced or paid and Notes for whose payment
     money has theretofore been deposited in trust and thereafter repaid to the
     Company) have been delivered to the Trustee for cancellation or, if no
     Trustee has been appointed, otherwise cancelled by the Company; or

          (b) if a Trustee has been appointed, all Notes that have not been
     delivered to the Trustee for cancellation have become due and payable by
     reason of the making of a notice of redemption or otherwise or will become
     due and payable within one year and the Company or any Guarantor has
     irrevocably deposited or caused to be deposited with the Trustee as trust
     funds in trust solely for the benefit of the Holders, cash in U.S. dollars,
     non-callable Government Securities, or a combination thereof, in such
     amounts as will be sufficient without consideration of any reinvestment of
     interest, to pay and discharge the entire indebtedness on the Notes not
     delivered to the Trustee for cancellation for principal, premium and
     Liquidated Damages, if any, and accrued interest to the date of maturity or
     redemption;

     (2) no Default or Event of Default has occurred and is continuing on the
date of such deposit or will occur as a result of such deposit and such deposit
will not result in a breach or violation of, or constitute a default under, any
other instrument to which the Company or any Guarantor is a party or by which
the Company or any Guarantor is bound;

     (3) the Company or any Guarantor has paid or caused to be paid all sums
payable by it under this Indenture; and

                                      -93-
<PAGE>

     (4) the Company has delivered irrevocable instructions to the Trustee under
this Indenture to apply the deposited money toward the payment of the Notes at
maturity or the redemption date, as the case may be.

In addition, the Company must deliver an Officers' Certificate and an Opinion of
Counsel to the Trustee stating that all conditions precedent to satisfaction and
discharge have been satisfied.

     Notwithstanding the satisfaction and discharge of this Indenture, if money
has been deposited with the Trustee pursuant to subclause (b) of clause (1) of
this Section, the provisions of Section 12.02 and Section 8.06 will survive. In
addition, nothing in this Section 12.01 will be deemed to discharge those
provisions of Section 7.07 hereof, that, by their terms, survive the
satisfaction and discharge of this Indenture.

     Section 12.02 Application of Trust Money.

     Subject to the provisions of Section 8.06, all money deposited with the
Trustee pursuant to Section 12.01 shall be held in trust and applied by it, in
accordance with the provisions of the Notes and this Indenture, to the payment,
either directly or through any Paying Agent (including the Company acting as its
own Paying Agent) as the Trustee may determine, to the Persons entitled thereto,
of the principal (and premium, if any) and interest for whose payment such money
has been deposited with the Trustee; but such money need not be segregated from
other funds except to the extent required by law.

     If the Trustee or Paying Agent is unable to apply any money or Government
Securities in accordance with Section 12.01 by reason of any legal proceeding or
by reason of any order or judgment of any court or governmental authority
enjoining, restraining or otherwise prohibiting such application, the Company's
and any Guarantor's obligations under this Indenture and the Notes shall be
revived and reinstated as though no deposit had occurred pursuant to Section
12.01; provided that if the Company has made any payment of principal of,
premium, if any, or interest on any Notes because of 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 or Government Securities held
by the Trustee or Paying Agent.

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

          (1) INTEREST. Metaldyne Corporation, a Delaware corporation (the
     "Company"), promises to pay interest on the principal amount of this Note
     at 10% per annum from January 1, 2004 until maturity and shall pay the
     Liquidated Damages, if any, payable pursuant to Section 2(d) of the
     Registration Rights Agreement referred to below. The Company will pay
     interest and Liquidated Damages, if any, semi-annually in arrears on
     January 15 and July 15 of each year, or if any such day is not a Business
     Day, on the next succeeding Business Day (each, an "Interest Payment
     Date"). Interest on the Notes will accrue from the most recent date to
     which interest has been paid or, if no interest has been paid, from the
     date of issuance; provided that if there is no existing Default in the
     payment of interest, and if this Note is authenticated between a record
     date referred to on the face hereof and the next succeeding Interest
     Payment Date, interest shall accrue from such next succeeding Interest
     Payment Date; provided, further, that the first Interest Payment Date shall
     be July 15, 2004. The Company will pay interest (including post-petition
     interest in any proceeding under any Bankruptcy Law) on overdue principal
     and premium, if any, from time to time on demand at a rate that is 1% per
     annum in excess of the rate then in effect; it will pay interest (including
     post-petition interest in any proceeding under any Bankruptcy Law) on
     overdue installments of interest and Liquidated Damages, if any, (without
     regard to any applicable grace periods) from time to time on demand at the
     same rate to the extent lawful. Interest will be computed on the basis of a
     360-day year of twelve 30-day months.

          (2) METHOD OF PAYMENT. The Company will pay interest on the Notes
     (except defaulted interest) and Liquidated Damages, if any, to the Persons
     who are registered Holders of Notes at the close of business on the January
     1 and July 1 next preceding the Interest Payment Date, even if such Notes
     are canceled after such record date and on or before such Interest Payment
     Date, except as provided in Section 2.12 of the Indenture with respect to
     defaulted interest. The Notes will be payable as to principal, premium and
     Liquidated Damages, if any, and interest at the office or agency of the
     Company maintained for such purpose within or without the City and State of
     New York, or, at the option of the Company, payment of interest and
     Liquidated Damages, if any, may be made by check mailed to the Holders at
     their addresses set forth in the register of Holders; provided that payment
     by wire transfer of immediately available funds will be required with
     respect to principal of and interest, premium and Liquidated Damages, if
     any, on, all Global Notes and all other Notes the Holders of which will
     have provided wire transfer instructions to the Company or the Paying
     Agent. Such payment will be in such

                                       A-2
<PAGE>

     coin or currency of the United States of America as at the time of payment
     is legal tender for payment of public and private debts.

          (3) PAYING AGENT AND REGISTRAR. Initially, the Company will act as
     Paying Agent and Registrar. The Company may change any Paying Agent or
     Registrar without notice to any Holder. The Company or any of its
     Subsidiaries may act in any such capacity.

          (4) INDENTURE. The Company issued the Notes under an Indenture dated
     as of December 31, 2003 (the "Indenture") among the Company, the Guarantors
     and the Trustee (if appointed). The terms of the Notes include those stated
     in the Indenture and those made part of the Indenture by reference to the
     Trust Indenture Act of 1939, as amended (15 U.S. Code ss.ss. 77aaa-77bbbb).
     The Notes are subject to all such terms, and Holders are referred to the
     Indenture and such Act for a statement of such terms, all of which are
     hereby incorporated by reference. To the extent any provision of this Note
     conflicts with the express provisions of the Indenture, the provisions of
     the Indenture shall govern and be controlling. The Notes are unsecured
     obligations of the Company limited to $31,746,000 in aggregate principal
     amount, plus amounts, if any, issued to pay Liquidated Damages on
     outstanding Notes as set forth in Paragraph 2 hereof.

          the Company will not have the option to redeem the Notes prior to
          January 15, 2009. Thereafter, the Company will have the option to
          redeem the Notes, in whole or in part, upon not less than 30 nor more
          than 60 days' notice, at the redemption prices (expressed as
          percentages of principal amount) set forth below plus accrued and
          unpaid interest and Liquidated Damages, if any, thereon to the
          applicable redemption date, if redeemed during the twelve-month period
          beginning on January 15th of the years indicated below:

          Year                                                  Percentage
          ----                                                  ----------

          2009............................................      105.000%
          2010............................................      103.333%
          2011............................................      101.667%
          2012............................................      100.000%

               (b) Notwithstanding the provisions of subparagraph (a) of this
          Paragraph 5, at any time prior to January 15, 2009, the Company may on
          one or more occasions redeem up to 35% of the aggregate principal
          amount of Notes issued under the Indenture at a redemption price equal
          to 110% of the aggregate principal amount, plus accrued and unpaid
          interest and Liquidated Damages, if any to the redemption date, with
          the net cash proceeds of one or more Equity Offerings; provided that
          (1) at least 65% in aggregate principal amount of the Notes issued
          under the Indenture remains outstanding immediately after the
          occurrence of such redemption and that such redemption (excluding
          Notes held by the Company and

                                       A-3
<PAGE>

          its Subsidiaries); and (2) the redemption occurs within 120 days of
          the date of the closing of such Equity Offering.

          (6) MANDATORY REDEMPTION. The Company will not be required to make
     mandatory redemption or sinking fund payments with respect to the Notes.

          (7) REPURCHASE AT OPTION OF HOLDER.

               (a) If there is a Change of Control, the Company will be required
          to make an offer (a "Change of Control Offer") to repurchase all or
          any part (equal to $1,000 or an integral multiple thereof) of each
          Holder's Notes at a purchase price equal to 101% of the aggregate
          principal amount thereof plus accrued and unpaid interest and
          Liquidated Damages thereon, if any, to the date of purchase (the
          "Change of Control Payment"). Within 15 days following any Change of
          Control, the Company will mail a notice to each Holder setting forth
          the procedures governing the Change of Control Offer as required by
          the Indenture.

               (b) If the Company or a Subsidiary consummates any Asset Sales,
          within five days of each date on which the aggregate amount of Excess
          Proceeds exceeds $25.0 million, the Company will commence an offer to
          all Holders of Notes and all holders of other Indebtedness that is
          pari passu with the Notes containing provisions similar to those set
          forth in the Indenture with respect to offers to purchase or redeem
          with the proceeds of sales of assets (an "Asset Sale Offer") pursuant
          to Section 3.09 of the Indenture to purchase the maximum principal
          amount of Notes and other pari passu Indebtedness that may be
          purchased out of the Excess Proceeds at an offer price in cash in an
          amount equal to 100% of the principal amount thereof plus accrued and
          unpaid interest and Liquidated Damages thereon, if any, to the date
          fixed for the closing of such offer, in accordance with the procedures
          set forth in the Indenture. To the extent that the aggregate amount of
          Notes and other pari passu Indebtedness tendered pursuant to an Asset
          Sale Offer is less than the Excess Proceeds, the Company (or such
          Subsidiary) may use such deficiency for any purpose not otherwise
          prohibited by the Indenture. If the aggregate principal amount of
          Notes and other pari passu Indebtedness surrendered by holders thereof
          exceeds the amount of Excess Proceeds, the Trustee shall select the
          Notes, or if no Trustee has been appointed, the Company shall select
          the Notes, and other pari passu Indebtedness to be purchased on a pro
          rata basis. Holders of Notes that are the subject of an offer to
          purchase will receive an Asset Sale Offer from the Company prior to
          any related purchase date and may elect to have such Notes purchased
          by completing the form entitled "Option of Holder to Elect Purchase"
          on the reverse of the Notes.

     transfer of any Notes for a period of 15 days before a selection of Notes
     to be redeemed or during the period between a record date and the
     corresponding Interest Payment Date.

          (10) PERSONS DEEMED OWNERS. The registered Holder of a Note may be
     treated as its owner for all purposes.

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

          (12) DEFAULTS AND REMEDIES. Events of Default and Remedies include
     those as set forth in Article 6 of the Indenture.

          (13) SUBORDINATION. Payment of principal, interest and premium and
     Liquidated Damages, if any, on the Notes is subordinated to the prior
     payment of Senior Debt on the terms provided in the Indenture.

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

          (15) NO RECOURSE AGAINST OTHERS. A director, officer, employee,
     incorporator or stockholder, of the Company or any of the Guarantors, as
     such, will not

                                       A-5
<PAGE>

     have any liability for any obligations of the Company or such Guarantor
     under the Notes, the Note Guarantees or the Indenture or for any claim
     based on, in respect of, or by reason of, such obligations or their
     creation. Each Holder by accepting a Note waives and releases all such
     liability. The waiver and release are part of the consideration for the
     issuance of the Notes.

          (16) AUTHENTICATION AND ENFORCEMENT. This Note will not be valid until
     authenticated by the manual signature of the Trustee or an authenticating
     agent. However, enforcement of this Note and provisions of the Indenture
     shall not require a signature by a counterparty.

          (17) ABBREVIATIONS. Customary abbreviations may be used in the name of
     a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (=
     tenants by the entireties), JT TEN (= joint tenants with right of
     survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A
     (= Uniform Gifts to Minors Act).

          (18) ADDITIONAL RIGHTS OF HOLDERS OF RESTRICTED DEFINITIVE NOTES. In
     addition to the rights provided to Holders of Notes under the Indenture,
     Holders of Restricted Definitive Notes will have all the rights set forth
     in the Registration Rights Agreement dated as of December 31, 2003, among
     the Company, the Guarantors and the Initial Holder (the "Registration
     Rights Agreement").

          (19) 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 the Trustee or the
     Company may 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.

          (20) GOVERNING LAW. The internal law of the State of New York will
     govern and be used to construe the Notes without giving effect to
     applicable principles of conflicts of law to the extent that the
     application of the laws of another jurisdiction would be required thereby.

     The Company will furnish to any Holder upon written request and without
charge a copy of the Indenture and/or the Registration Rights Agreement.

Capitalized terms used but not defined herein shall have the meanings given to

     In connection with our proposed purchase of $____________ aggregate

     1. We understand that any subsequent transfer of the Notes or any interest
therein is subject to certain restrictions and conditions set forth in the
Indenture and the undersigned agrees to be bound by, and not to resell, pledge
or otherwise transfer the Notes or any interest therein except in compliance
with, such restrictions and conditions and the Securities Act of 1933, as
amended (the "Securities Act").

     2. We understand that the offer and sale of the Notes have not been
registered under the Securities Act, and that the Notes and any interest therein
may not be offered or sold except as permitted in the following sentence. We

                    TO BE DELIVERED BY SUBSEQUENT GUARANTORS]

     SUPPLEMENTAL INDENTURE (this "Supplemental Indenture"), dated as of

Subsidiary"), a subsidiary of Metaldyne Corporation (or its permitted
successor), a Delaware corporation (the "Company"), the Company, the other
Guarantors (as defined in the Indenture referred to herein) and [ ], as trustee
under the Indenture referred to below (the "Trustee").

                               W I T N E S S E T H

     WHEREAS, the Company has heretofore executed and delivered to the Trustee
an Indenture (the "Indenture"), dated as of December 31, 2003 providing for the
issuance of an aggregate principal amount of up to $31,746,000 of 10% Senior
Subordinated Notes due 2014 (the "Notes");

     WHEREAS, the Indenture provides that under certain circumstances the
Guaranteeing Subsidiary shall execute and deliver to the Trustee a supplemental
indenture pursuant to which the Guaranteeing Subsidiary shall unconditionally
guarantee all of the Company's Obligations under the Notes and the Indenture on
the terms and conditions set forth herein (the "Note Guarantee"); and

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

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

     1. CAPITALIZED TERMS. Capitalized terms used herein without definition
shall have the meanings assigned to them in the Indenture.

     2. AGREEMENT TO GUARANTEE. The Guaranteeing Subsidiary hereby agrees as
follows:

          (a) Along with all Guarantors named in the Indenture, to jointly and
     severally Guarantee to each Holder of a Note authenticated and delivered by
     the Trustee and to the Trustee and its successors and assigns, the Notes or
     the obligations of the Company hereunder or thereunder, that:

               (i) the principal of, and premium and Liquidated Damages, if any,
          and interest on the Notes will be promptly paid in full when due,
          whether at maturity, by acceleration, redemption or otherwise, and
          interest on the overdue principal of and interest on the Notes, if
          any, if lawful, and all other obligations of the Company to the
          Holders or the Trustee hereunder or thereunder will be promptly paid

          thereof; and

                                      F-1
<PAGE>

               (ii) in case of any extension of time of payment or renewal of
          any Notes or any of such other obligations, that same will be promptly
          paid in full when due or performed in accordance with the terms of the
          extension or renewal, whether at stated maturity, by acceleration or
          otherwise. Failing payment when due of any amount so guaranteed or any
          performance so guaranteed for whatever reason, the Guarantors shall be
          jointly and severally obligated to pay the same immediately.

          (b) The obligations hereunder shall be unconditional, irrespective of
     the validity, regularity or enforceability of the Notes or the Indenture,
     the absence of any action to enforce the same, any waiver or consent by any
     Holder of the Notes with respect to any provisions hereof or thereof, the
     recovery of any judgment against the Company, any action to enforce the
     same or any other circumstance which might otherwise constitute a legal or
     equitable discharge or defense of a Guarantor.

          (c) The following is hereby waived: diligence, presentment, demand of
     payment, filing of claims with a court in the event of insolvency or
     bankruptcy of the Company, any right to require a proceeding first against
     the Company, protest, notice and all demands whatsoever.

          (d) This Note Guarantee shall not be discharged except by complete
     performance of the obligations contained in the Notes and the Indenture,
     and the Guaranteeing Subsidiary accepts all obligations of a Guarantor
     under the Indenture.

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

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

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

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

                                      F-2
<PAGE>

          (i) Pursuant to Section 10.02 of the Indenture, after giving effect to
     any maximum amount and all other contingent and fixed liabilities that are
     relevant under any applicable Bankruptcy or fraudulent conveyance laws, and
     after giving effect to any collections from, rights to receive contribution
     from or payments made by or on behalf of any other Guarantor in respect of
     the obligations of such other Guarantor under Article 10 of the Indenture,
     this new Note Guarantee shall be limited to the maximum amount permissible
     such that the obligations of such Guarantor under this Note Guarantee will
     not constitute a fraudulent transfer or conveyance.

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

     4. Guaranteeing Subsidiary may Consolidate, etc. on Certain Terms.

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

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

               (ii) either (A) subject to Sections 11.05 and 11.06 of the
          Indenture, the Person acquiring the property in any such sale or
          disposition or the Person formed by or surviving any such
          consolidation or merger unconditionally assumes all the obligations of
          that Guarantor, pursuant to a supplemental indenture in form and
          substance reasonably satisfactory to the Trustee, under the Notes, the
          Indenture and the Note Guarantee on the terms set forth herein or
          therein; or (B) the Net Proceeds of such sale or other disposition are
          applied in accordance with the applicable provisions of the Indenture,
          including without limitation, Section 4.10 thereof.

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

                                      F-3
<PAGE>

          (c) Except as set forth in Articles 4 and 5 and Section 11.06 of the
     Indenture, and notwithstanding clauses (a) and (b) above, nothing contained
     in the Indenture or in any of the Notes shall prevent any consolidation or
     merger of a Guarantor with or into the Company or another Guarantor, or
     shall prevent any sale or conveyance of the property of a Guarantor as an
     entirety or substantially as an entirety to the Company or another
     Guarantor.

     5. Releases.

          (a) In the event of any sale or other disposition of all or
     substantially all of the assets of any Guarantor, by way of merger,
     consolidation or otherwise, or a sale or other disposition of all of the
     capital stock of any Guarantor, in each case to a Person that is not
     (either before or after giving effect to such transaction) a Restricted
     Subsidiary of the Company, then such Guarantor (in the event of a sale or
     other disposition, by way of merger, consolidation or otherwise, of all of
     the capital stock of such Guarantor) or the corporation acquiring the
     property (in the event of a sale or other disposition of all or
     substantially all of the assets of such Guarantor) will be released and
     relieved of any obligations under its Note Guarantee; provided that the Net
     Proceeds of such sale or other disposition are applied in accordance with
     the applicable provisions of the Indenture, including without limitation
     Section 4.10 of the Indenture. Upon delivery by the Company to the Trustee
     of an Officers' Certificate and an Opinion of Counsel to the effect that
     such sale or other disposition was made by the Company in accordance with
     the provisions of the Indenture, including without limitation Section 4.10
     of the Indenture, the Trustee shall execute any documents reasonably
     required in order to evidence the release of any Guarantor from its
     obligations under its Note Guarantee.

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

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

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

                                      F-4
<PAGE>

     8. COUNTERPARTS. The parties may sign any number of copies of this
Supplemental Indenture. Each signed copy shall be an original, but all of them
together represent the same agreement.

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

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

                                      F-5

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