          basis to such Indebtedness as if such Indebtedness had been Incurred
          on the first day of such period and the discharge of any other
          Indebtedness repaid, repurchased, defeased or otherwise discharged
          with the proceeds of such new Indebtedness as if such discharge had
          occurred on the first day of such period,

          of the Company or any Restricted Subsidiary repaid, repurchased,
          defeased or otherwise discharged with respect to the Company and its
          continuing Restricted Subsidiary is sold, the Indebtedness of such
          Restricted Subsidiary to the extent the Company and its continuing
          Restricted Subsidiaries are no longer liable for such Indebtedness

          substantially all of an operating unit of a business, Indebtedness and
          EBITDA for such period shall be calculated after giving pro forma
          effect thereto (including the Incurrence of any Indebtedness) as if
          such Investment or acquisition occurred on the first day of such
          period, and


                                                                               8

without interest coupons and only in denominations of $1,000 and integral

          SECTION 2.02.  Execution and Authentication.  One Officer shall sign
                         -----------------------------
the Securities for the Company by manual or facsimile signature.

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

          A Security shall not be valid until an authorized signatory of the
Trustee manually signs the certificate of authentication on the Security.  The
signature shall be conclusive evidence that the Security has been authenticated
under this Indenture.

          The Trustee shall authenticate and make available for delivery
Securities as set forth in the Appendix.

          In authenticating the Securities and accepting the additional
responsibilities under this Indenture in relation to such Securities, the
Trustee shall be entitled to receive, and shall be fully protected in relying
upon:

          (a) A copy of the resolution or resolutions of the Board of Directors
in or pursuant to which the terms and form of the Securities were established,
certified by the secretary or an assistant secretary of the Company to have been
duly adopted by the Board of Directors and to be in full force and effect as of
the date of such certificate, and if the terms and form of such


                                                                              24

Securities are established by an Officers' Certificate pursuant to general
authorization of the Board of Directors, such Officers' Certificate;

          (b)   an Opinion of Counsel which shall state:

          (i)   that the form of such Securities has been established by or
     pursuant to a resolution of the Board of Directors in conformity with the
     provisions of this Indenture;

          (ii)  that the terms of such Securities have been established in
     conformity with the other provisions of this Indenture;

          (iii) that such Securities, when authenticated and delivered by the
     Trustee and issued by the Company in the manner and subject to any
     conditions specified in such Opinion of Counsel, will constitute valid and
     legally binding obligations of the Company, enforceable in accordance with
     their terms, subject to bankruptcy, insolvency, reorganization and other
     laws of general applicability relating to or affecting the enforcement of
     creditors' rights and to general equity principles.

          The Trustee shall have the right to decline to authenticate and
deliver any Securities under this Section 2.02 if the Trustee, being advised by
counsel, determines that such action may not lawfully be taken or if the Trustee
in good faith shall determine that such action would expose the Trustee to
personal liability to existing Holders.

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

          SECTION 2.03.  Registrar and Paying Agent.  (a) The Company shall
                         ---------------------------
maintain an office or agency where Securities may be presented for registration
of transfer or for exchange (the "Registrar") and an office or agency where
Securities may be presented for payment (the "Paying Agent").  The Registrar
shall keep a register of the Securities and of their transfer and exchange.  The
Company may have one or more co-registrars and one or more additional paying
agents. The term "Paying Agent" includes any additional paying agent, and the
term "Registrar" includes any co-registrars. The Company initially appoints the
Trustee as (i) Registrar and Paying Agent in connection with the Securities and
(ii) the Securities Custodian with respect to the Global Securities.

          (b) The Company shall enter into an appropriate agency agreement with
any Registrar or Paying Agent not a party to this Indenture, which shall
incorporate the terms of the TIA.  The agreement shall implement the provisions
of this Indenture that relate to such agent.  The Company shall notify the
Trustee of the name and address of any such agent.  If the


                                                                              25

Company fails to maintain a Registrar or Paying Agent, the Trustee shall act as
such and shall be entitled to appropriate compensation therefor pursuant to
Section 7.07. The Company or any of its domestically organized Wholly Owned
Subsidiaries may act as Paying Agent or Registrar.

          (c) The Company may remove any Registrar or Paying Agent upon written
notice to such Registrar or Paying Agent and to the Trustee; provided, however,
                                                             --------  -------
that no such removal shall become effective until (i) acceptance of an
appointment by a successor as evidenced by an appropriate agreement entered into
by the Company and such successor Registrar or Paying Agent, as the case may be,
and delivered to the Trustee or (ii) notification to the Trustee that the
Trustee shall serve as Registrar or Paying Agent until the appointment of a
successor in accordance with clause (i) above.  The Registrar or Paying Agent
may resign at any time upon written notice to the Company and the Trustee.

          SECTION 2.04.  Paying Agent to Hold Money in Trust.  Subject to
                         ------------------------------------
Section 13.08, prior to each due date of the principal and interest on any
Security, the Company shall deposit with the Paying Agent (or if the Company or
a Subsidiary is acting as Paying Agent, segregate and hold in trust for the
benefit of the Persons entitled thereto) a sum sufficient to pay such principal
and interest when so becoming due.  The Company shall require each Paying Agent
(other than the Trustee) to agree in writing that the Paying Agent shall hold in
trust for the benefit of Holders or the Trustee all money held by the Paying
Agent for the payment of principal of or interest on the Securities, shall
notify the Trustee of any default by the Company in making any such payment.  If
the Company or a Subsidiary of the Company acts as Paying Agent, it shall
segregate the money held by it as Paying Agent and hold it as a separate trust
fund.  The Company at any time may require a Paying Agent to pay all money held
by it to the Trustee and to account for any funds disbursed by the Paying Agent.
Upon complying with this Section, the Paying Agent shall have no further
liability for the money delivered to the Trustee.

          SECTION 2.05.  Holder Lists.  The Trustee shall preserve in as current
                         -------------
a form as is reasonably practicable the most recent list available to it of the
names and addresses of Holders.  If the Trustee is not the Registrar, the
Company shall furnish, or cause the Registrar to furnish, to the Trustee, in
writing at least five Business Days before each interest payment date and at
such other times as the Trustee may request in writing, a list in such form and
as of such date as the Trustee may reasonably require of the names and addresses
of Holders.

          SECTION 2.06.  Transfer and Exchange.  The Securities shall be issued
                         ----------------------
in registered form and shall be transferable only upon the surrender of a
Security for registration of transfer and in compliance with the Appendix.  When
a Security is presented to the Registrar with a request to register a transfer,
the Registrar shall register the transfer as requested if its requirements
therefor are met.  When Securities are presented to the Registrar with a request
to exchange them for an equal principal amount of Securities of other
denominations, the Registrar shall make the exchange as requested if the same
requirements are met.  To permit registration of transfers and exchanges, the
Company shall execute and the Trustee shall authenticate Securities at the
Registrar's request.  The Company may require payment of a sum sufficient to pay
all taxes, assessments or other governmental charges in connection with any
transfer or exchange pursuant to this Section.  The Company shall not be
required to make and the Registrar need not


                                                                              26

register transfers or exchanges of Securities selected for redemption (except,
in the case of Securities to be redeemed in part, the portion thereof not to be
redeemed) or to transfer or exchange any Securities for a period of 15 days
before a selection of Securities to be redeemed.

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

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

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

          SECTION 2.07.  Replacement Securities.  If a mutilated Security is
                         -----------------------
surrendered to the Registrar or if the Holder of a Security claims that the
Security has been lost, destroyed or wrongfully taken, the Company shall issue
and the Trustee shall authenticate a replacement Security if the requirements of
Section 8-405 of the Uniform Commercial Code are met, such that the Holder (a)
satisfies the Company or the Trustee within a reasonable time after he has
notice of such loss, destruction or wrongful taking and the Registrar does not
register a transfer prior to receiving such notification, (b) makes such request
to the Company or the Trustee prior to the Security being acquired by a
protected purchaser as defined in Section 8-303 of the Uniform Commercial Code
(a "protected purchaser") and (c) satisfies any other reasonable requirements of
the Trustee (including, without limitation, obtaining from the Company an
Officers' Certificate stating that the requirements of Section 8-405 of the UCC
have been met).  If required by the Trustee or the Company, such Holder shall
furnish an indemnity bond sufficient in the judgment of the Trustee to protect
the Company, the Trustee, the Paying Agent and the Registrar from any loss that
any of them may suffer if a Security is replaced.  The Company and the Trustee
may charge the Holder for their expenses in replacing a Security.  In the event
any such mutilated, lost, destroyed or wrongfully taken Security has become or
is about to become due and payable, the Company in its discretion may pay such
Security instead of issuing a new Security in replacement thereof.

          Every replacement Security is an additional obligation of the Company.


                                                                              27

          The provisions of this Section 2.07 are exclusive and shall preclude
(to the extent lawful) all other rights and remedies with respect to the
replacement or payment of mutilated, lost, destroyed or wrongfully taken
Securities.

          SECTION 2.08.  Outstanding Securities.  Securities outstanding at any
                         -----------------------
time are all Securities authenticated by the Trustee except for those canceled
by it, those delivered to it for cancelation and those described in this Section
as not outstanding.  Subject to Section 13.06, a Security does not cease to be
outstanding because the Company or an Affiliate of the Company holds the
Security.

          If a Security is replaced pursuant to Section 2.07, it ceases to be
outstanding unless the Trustee and the Company receive proof satisfactory to
them that the replaced Security is held by a protected purchaser.

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

          SECTION 2.09.  Temporary Securities.  In the event that Definitive

Securities are to be issued under the terms of this Indenture, until such
Definitive Securities are ready for delivery, the Company may prepare and the
Trustee shall authenticate temporary Securities.  Temporary Securities shall be
substantially in the form of Definitive Securities but may have variations that
the Company considers appropriate for temporary Securities.  Without
unreasonable delay, the Company shall prepare and the Trustee shall authenticate
Definitive Securities and deliver them in exchange for temporary Securities upon
surrender of such temporary Securities at the office or agency of the Company,
without charge to the Holder.

          SECTION 2.10.  Cancelation.  The Company at any time may deliver
                         ------------
Securities to the Trustee for cancelation.  The Registrar and the Paying Agent
shall forward to the Trustee any Securities surrendered to them for registration
of transfer, exchange or payment.  The Trustee and no one else shall cancel all
Securities surrendered for registration of transfer, exchange, payment or
cancelation and shall dispose of canceled Securities in accordance with its
customary procedures or deliver canceled Securities to the Company pursuant to
written direction by an Officer, provided, however, that the Trustee shall not
                                 --------  -------
be required to destroy Securities.  The Company may not issue new Securities to
replace Securities it has redeemed, paid or delivered to the Trustee for
cancelation.  The Trustee shall not authenticate Securities in place of canceled
Securities other than pursuant to the terms of this Indenture.

          SECTION 2.11.  Defaulted Interest.  If the Company defaults in a
                         -------------------
payment of interest on the Securities, the Company shall pay the defaulted

lawful manner.  The Company may pay the


                                                                              28

defaulted interest to the Persons who are Holders on a subsequent special record
date. The Company shall fix or cause to be fixed any such special record date
and payment date to the reasonable satisfaction of the Trustee and shall
promptly mail or cause to be mailed to each Holder a notice that states the
special record date, the payment date and the amount of defaulted interest to be
paid.

          SECTION 2.12.  CUSIP and "ISIN" Numbers.  The Company in issuing the
                         -------------------------
Securities may use "CUSIP" and "ISIN" numbers (if then generally in use) and, if
so, the Trustee shall use "CUSIP" and "ISIN" numbers in notices of redemption as
a convenience to Holders; provided, however, that any such notice may state that
                          --------  -------
no representation is made as to the correctness of such numbers either as
printed on the Securities or as contained in any notice of a redemption and that
reliance may be placed only on the other identification numbers printed on the
Securities, and any such redemption shall not be affected by any defect in or
omission of such numbers.

                                   ARTICLE 3

                                  Redemption

to be redeemed.

          The Company shall give each notice to the Trustee provided for in this
Section at least 60 days before the redemption date unless the Trustee consents
to a shorter period.  Such notice shall be accompanied by an Officers'
Certificate and an Opinion of Counsel from the Company to the effect that such
redemption will comply with the conditions herein.   Any such notice may be
canceled at any time prior to notice of such redemption being mailed to any
Holder by written notice thereof to the Trustee and shall thereby be void and of
no effect.

          SECTION 3.02.  Selection of Securities To Be Redeemed.  If fewer than
                         ---------------------------------------
all the Securities are to be redeemed, the Trustee shall select the Securities
to be redeemed pro rata or by lot or by such other method that the Trustee shall
deem to be fair and appropriate.  The Trustee shall make the selection from
outstanding Securities not previously called for redemption.  The Trustee may
select for redemption portions of the principal of Securities that have
denominations larger than $1,000.  Securities and portions of them the Trustee
selects shall be in amounts of $1,000 or a whole multiple of $1,000.  Provisions
of this Indenture that apply to Securities called for redemption also apply to
portions of Securities called for redemption.  The Trustee shall notify the
Company promptly of the Securities or portions of Securities to be redeemed.

          SECTION 3.03.  Notice of Redemption.  (a) At least 30 days but not
                         ---------------------
more than 60 days before a date for redemption of Securities, the Company shall
mail a notice of redemption


                                                                              29

by first-class mail to each Holder of Securities to be redeemed at such Holder's
registered address.

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

          (i)    the redemption date;

          (ii)   the redemption price and the amount of accrued interest to the
     redemption date;

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

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

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

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

          (vii)  the CUSIP or ISIN number, if any, printed on the Securities
     being redeemed; and

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

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

          SECTION 3.04.  Effect of Notice of Redemption.  Once notice of
                         -------------------------------
redemption is mailed, Securities called for redemption become due and payable on
the redemption date and at the redemption price stated in the notice.  Upon
surrender to the Paying Agent, such Securities shall be paid at the redemption
price stated in the notice, plus accrued interest and liquidated damages, if
any, to the redemption date; provided, however,  that if the redemption date is
                             --------  -------
after a regular record date and on or prior to the interest payment date, the
accrued interest and liquidated damages, if any, shall be payable to the Holder
of the redeemed Securities registered on the relevant record date.  Failure to
give notice or any defect in the notice to any Holder shall not affect the
validity of the notice to any other Holder.

          SECTION 3.05.  Deposit of Redemption Price.  Prior to 10:00 a.m. on
                         ----------------------------

damages, if any, on all Securities to be redeemed on that date other than
Securities or portions of Securities called for redemption that have been

redemption date, interest will cease to accrue on Securities or portions thereof
called for redemption so long as the Company has deposited with the Paying Agent
funds sufficient to pay the principal of, plus accrued and unpaid interest and
liquidated damages, if any, on, the Securities to be redeemed, unless the Paying
Agent is prohibited from making such payment pursuant to the terms of this
Indenture.

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

                                   ARTICLE 4

                                   Covenants

          SECTION 4.01.  Payment of Securities.  The Company shall promptly pay
                         ----------------------
the principal of and interest on the Securities on the dates and in the manner
provided in the Securities and in this Indenture.  Principal and interest shall
be considered paid on the date due if on such date the Trustee or the Paying
Agent holds in accordance with this Indenture money sufficient to pay all
principal and interest then due and the Trustee or the Paying Agent, as the case
may be, is not prohibited from paying such money to the Holders on that date
pursuant to the terms of this Indenture.

          The Company shall pay interest on overdue principal at the rate
specified therefor in the Securities, and it shall pay interest on overdue
installments of interest at the same rate to the extent lawful.

          SECTION 4.02.  SEC Reports.  Notwithstanding that the Company may not
                         ------------
be subject to the reporting requirements of Section 13 or 15(d) of the Exchange
Act, the Company shall file with the SEC (if it will accept such filing), and
provide the Trustee and Holders and prospective Holders (upon request) within 15
days after it files them with the SEC, copies of its annual report and the
information, documents and other reports that are specified in Sections 13 and
15(d) of the Exchange Act.  In addition, following a Public Equity Offering, the
Company shall furnish to the Trustee and the Holders, promptly upon their
becoming available, copies of the annual report to shareholders and any other
information provided by the Company, Holdings or Parent to its public
shareholders generally.  The Company also shall comply with the other provisions
of TIA ' 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


                                                                              31

notice of any information contained therein, including the Company's compliance
with any of its covenants hereunder (as to which the Trustee is entitled to rely
exclusively on Officers' Certificates).

          SECTION 4.03. Limitation on Indebtedness.  (a) The Company shall
                        ---------------------------
not, and shall not permit any Restricted Subsidiary to, Incur, directly or
indirectly, any Indebtedness; provided, however, that the Company and the Note
                              --------  -------
Guarantors may Incur Indebtedness if on the date of such Incurrence and after
giving effect thereto, the Consolidated Coverage Ratio would be greater than
2.00 to 1 if such Indebtedness is Incurred on or prior to December 31, 2001 and
2.25 to 1 if such Indebtedness is Incurred thereafter.

          (b)   Notwithstanding Section 4.03(a), the Company and its Restricted
Subsidiaries may Incur the following Indebtedness:

          (i)   (1) Bank Indebtedness in an aggregate principal amount not to
     exceed $250.0 million less the aggregate amount of all prepayments of
     principal applied to permanently reduce any such Indebtedness pursuant to
     Section 4.06 and (2) (A) Indebtedness under the Acquisition Term Loan
     Facility in an aggregate principal amount not to exceed $40.0 million less
     the aggregate amount of all prepayments applied to permanently reduce any
     principal of such Indebtedness pursuant to Section 4.06; provided, however,
                                                              --------  -------
     that at the time the Company or any Restricted Subsidiary Incurs any
     Indebtedness under this Section 4.06(b)(i)(2), the Company has a
     Consolidated Leverage Ratio of 5.00:1 or less, and (B) any Refinancing
     Indebtedness in respect thereof;

          (ii)  Indebtedness of the Company owed to and held by any Wholly Owned
     Subsidiary or Indebtedness of a Restricted Subsidiary owed to and held by
     the Company or any Wholly Owned Subsidiary; provided, however, that (1) any
                                                 --------  -------
     subsequent issuance or transfer of any Capital Stock or any other event
     that results in any such Wholly Owned Subsidiary ceasing to be a Wholly
     Owned Subsidiary or any subsequent transfer of any such Indebtedness
     (except to the Company or a Wholly Owned Subsidiary) shall be deemed, in
     each case, to constitute the Incurrence of such Indebtedness by the issuer
     thereof, (2) if the Company is the obligor on such Indebtedness, such
     Indebtedness is made subordinate and junior in right of payment to the
     Securities and (3) if a Restricted Subsidiary that is a Note Guarantor is
     the obligor on such Indebtedness and such Indebtedness is owed to and held
     by a Wholly Owned Subsidiary that is not a Note Guarantor, such
     Indebtedness is expressly subordinated to the prior payment in full in cash
     of all obligations of such Restricted Subsidiary with respect to its Note
     Guarantee;

          (iii) Indebtedness (1) represented by the Securities and the Note
     Guarantees, (2) outstanding on the Closing Date (other than the
     Indebtedness described in clauses (i) and (ii) above), (3) consisting of
     Refinancing Indebtedness Incurred in respect of any Indebtedness described
     in this clause (iii) (including Indebtedness that is Refinancing
     Indebtedness) or Section 4.03(a), (4) consisting of Guarantees of any
     Indebtedness permitted under clauses (i) and (ii) of this paragraph (b) and
     (5) consisting of (i) Guarantees by the Company of Indebtedness or other
     obligations of any of its


                                                                              32

     Restricted Subsidiaries or (ii) Guarantees by any Note Guarantor of
     Indebtedness of the Company or a Restricted Subsidiary, in each case so
     long as the Incurrence of the Indebtedness being Guaranteed is permitted
     under the terms of this Indenture; provided that if such Guaranteed
                                        --------
     Indebtedness is by its express terms subordinated in right of payment to
     the Securities or the Note Guarantee of such Restricted Subsidiary, as
     applicable, any such Guarantee of the Company or such Note Guarantor with
     respect to such Indebtedness shall be subordinated in right of payment to
     the Securities or such Note Guarantor's Note Guarantee with respect to the
     Securities substantially to the same extent as such Indebtedness is
     subordinated to the Securities or the Note Guarantee of such Restricted
     Subsidiary, as applicable;

          (iv)  (1) Indebtedness of a Restricted Subsidiary Incurred and
     outstanding on or prior to the date on which such Restricted Subsidiary was
     acquired (including by way of merger) by the Company or any Restricted
     Subsidiary (other than Indebtedness Incurred as consideration in, or to
     provide all or any portion of the funds or credit support utilized to
     consummate, the transaction or series of related transactions pursuant to
     which such Restricted Subsidiary became a Subsidiary of or was otherwise
     acquired by the Company); provided, however, that on the date that such
                               --------  -------
     Restricted Subsidiary is acquired, the Company or such Restricted
     Subsidiary would have been able to Incur such Indebtedness under this
     Section 4.03 and (2) Refinancing Indebtedness Incurred by a Restricted
     Subsidiary in respect of Indebtedness Incurred by such Restricted
     Subsidiary pursuant to this clause (iv);

          (v)   Indebtedness (1) in respect of performance bonds, bankers'
     acceptances, letters of credit and surety or appeal bonds provided by the
     Company or the Restricted Subsidiaries in the ordinary course of their
     business, and (2) under Currency Agreements, Interest Rate Agreements and
     Commodity Agreements entered into for bona fide hedging purposes of the
     Company or a Restricted Subsidiary in the ordinary course of business;
     provided, however, that such agreements do not increase the Indebtedness of
     --------  -------
     the Company or the Restricted Subsidiaries outstanding at any time other
     than as a result of fluctuations in interest rates, currency exchange rates
     or commodity prices or by reason of fees, indemnities and compensation
     payable thereunder;

          (vi)  Indebtedness (including Capitalized Lease Obligations and
     Attributable Debt) incurred by the Company or any of the Restricted
     Subsidiaries to finance the purchase, lease or improvements of property
     (real or personal) or equipment (whether through the direct purchase of
     assets or the Capital Stock of any Person owning such assets) in an
     aggregate principal amount which, when aggregated with the principal amount
     of all other Indebtedness then outstanding and incurred pursuant to this
     clause (vi) and all Refinancing Indebtedness incurred to refund, refinance
     or replace any Indebtedness incurred pursuant to this clause (vi), does not
     exceed the greater of $25.0 million or 5.0% of Total Assets;

          (vii) Indebtedness of Foreign Subsidiaries in an aggregate principal
     amount not to exceed $15.0 million outstanding at any one time; or


                                                                              33

          (viii)  Indebtedness (other than Indebtedness permitted to be Incurred
     pursuant to Section 4.03(a) or any other clause of this paragraph (b)) in
     an aggregate principal amount on the date of Incurrence that, when added to
     all other Indebtedness Incurred pursuant to this clause (viii) and then
     outstanding, shall not exceed $30.0 million.

          (c) Notwithstanding the foregoing, the Company shall not Incur any
Indebtedness pursuant to Section 4.03(b) above if the proceeds thereof are used,
directly or indirectly, to repay, prepay, redeem, defease, retire, refund or
refinance any Subordinated Obligations unless such Indebtedness shall be
subordinated to the Securities to at least the same extent as such Subordinated
Obligations. The Company shall not Incur any Indebtedness if such Indebtedness
is subordinate or junior in ranking in any respect to any Senior Indebtedness
unless such Indebtedness is Senior Subordinated Indebtedness or is expressly
subordinated in right of payment to Senior Subordinated Indebtedness. In
addition, the Company shall not Incur any Secured Indebtedness which is not
Senior Indebtedness unless contemporaneously therewith effective provision is
made to secure the Securities equally and ratably with (or on a senior basis to,
in the case of Indebtedness subordinated in right of payment to the Securities)
such Secured Indebtedness for so long as such Secured Indebtedness is secured by
a Lien. A Note Guarantor shall not Incur any Indebtedness if such Indebtedness
is by its terms expressly subordinate or junior in ranking in any respect to any
Senior Indebtedness of such Note Guarantor unless such Indebtedness is Senior
Subordinated Indebtedness of such Note Guarantor or is expressly subordinated in
right of payment to Senior Subordinated Indebtedness of such Note Guarantor. In
addition, a Note Guarantor shall not Incur any Secured Indebtedness that is not
Senior Indebtedness of such Note Guarantor unless contemporaneously therewith
effective provision is made to secure the Note Guarantee of such Note Guarantor
equally and ratably with (or on a senior basis to, in the case of Indebtedness
subordinated in right of payment to such Note Guarantee) such Secured
Indebtedness for as long as such Secured Indebtedness is secured by a Lien.

          (d) Notwithstanding any other provision of this Section 4.03, the
maximum amount of Indebtedness that the Company or any Restricted Subsidiary may
Incur pursuant to this Section shall not be deemed to be exceeded solely as a
result of fluctuations in the exchange rates of currencies. For purposes of
determining the outstanding principal amount of any particular Indebtedness
Incurred pursuant to this Section 4.03, (i) Indebtedness Incurred pursuant to
the Credit Agreement prior to or on the Closing Date shall be treated as
Incurred pursuant to Section 4.03(b)(i), (ii) Indebtedness permitted by this
Section 4.03 need not be permitted solely by reference to one provision
permitting such Indebtedness but may be permitted in part by one such provision
and in part by one or more other provisions of this Section permitting such
Indebtedness, and (iii) in the event that Indebtedness meets the criteria of
more than one of the types of Indebtedness described in this Section 4.03, the
Company, in its sole discretion, shall classify such Indebtedness and only be
required to include the amount of such Indebtedness in one of such clauses, and
may from time to time reclassify Indebtedness permitted under Section 4.03(b)
among the different clauses thereof.


                                                                              34

          SECTION 4.04.  Limitation on Restricted Payments.  (a) The Company
                         ----------------------------------
shall not, and shall not permit any Restricted Subsidiary, directly or
indirectly, to (i) declare or pay any dividend or make any distribution on or in
respect of its Capital Stock or make any similar payment (including any payment
in connection with any merger or consolidation involving the Company or any
Subsidiary of the Company) to the direct or indirect holders of its Capital
Stock except (A) dividends or distributions payable solely in its Capital Stock
(other than Disqualified Stock) and (B) dividends or distributions payable to
the Company or a Restricted Subsidiary (and, if such Restricted Subsidiary has
shareholders other than the Company or other Restricted Subsidiaries, to its
other shareholders on a pro rata basis), (ii) purchase, repurchase, redeem,
retire or otherwise acquire for value any Capital Stock of (A) Parent, Holdings
or the Company held by Persons other than the Company or a Restricted Subsidiary
or (B) any Restricted Subsidiary (other than Preferred Stock that is not Voting
Stock) held by any Affiliate of the Company (other than Restricted Subsidiary),
(iii) purchase, repurchase, redeem, retire, defease or otherwise acquire for
value, prior to scheduled maturity, scheduled repayment or scheduled sinking
fund payment any Subordinated Obligations of the Company or any Note Guarantor
(other than the purchase, repurchase, redemption, retirement, defeasance or
other acquisition for value of Subordinated Obligations acquired in anticipation
of satisfying a sinking fund obligation, principal installment or final
maturity, in each case due within one year of the date of acquisition) or (iv)
make any Investment (other than a Permitted Investment) in any Person (any such
dividend, distribution, payment, purchase, redemption, repurchase, defeasance,
retirement or other acquisition or Investment being herein referred to as a
"Restricted Payment") if at the time the Company or such Restricted Subsidiary
makes such Restricted Payment:

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

          (2)  the Company could not Incur at least $1.00 of additional
     Indebtedness under Section 4.03(a); or

          (3)  the aggregate amount of such Restricted Payment and all other
     Restricted Payments (the amount so expended, if other than in cash, to be
     determined in good faith by the Board of Directors, whose determination
     shall be conclusive and evidenced by a resolution of the Board of
     Directors) declared or made subsequent to the Closing Date would exceed the
     sum, without duplication, of:

               (A)  50% of the Consolidated Net Income accrued during the period
          (treated as one accounting period) from the beginning of the fiscal
          quarter immediately following the fiscal quarter during which the
          Closing Date occurs to the end of the most recent fiscal quarter
          ending at least 45 days prior to the date of such Restricted Payment
          (or, in case such Consolidated Net Income shall be a deficit, minus
          100% of such deficit);

     such Restricted Subsidiary became a Restricted Subsidiary or was otherwise

     Indebtedness permitted to be Incurred by a Restricted Subsidiary subsequent
     to the Closing Date pursuant to Section 4.03; provided, however, that any
     such encumbrance or restrictions are reasonable and customary with respect
     to the type of Indebtedness being Incurred (under the relevant
     circumstances).

          SECTION 4.06.  Limitation on Sales of Assets and Subsidiary Stock.
                         ---------------------------------------------------
(a)  The Company shall not, and shall not permit any Restricted Subsidiary to,
make any Asset Disposition unless (i) the Company or such Restricted Subsidiary
receives consideration (including by way of relief from, or by any other Person
assuming sole responsibility for, any liabilities, contingent or otherwise) at
the time of such Asset Disposition at least equal to the Fair Market Value of
the shares and assets subject to such Asset Disposition, (ii) except in the case
of a Permitted Asset Swap, at least 75% of the consideration thereof received by
the Company or such Restricted Subsidiary is in the form of cash and (iii) an
amount equal to 100% of the Net Available Cash from such Asset Disposition is
applied by the Company (or such Restricted Subsidiary, as the case may be) (1)
first, to the extent the Company elects (or is required by the terms of any
- -----
Indebtedness), to prepay, repay, purchase, repurchase, redeem, retire, defease
or otherwise acquire for value Senior Indebtedness of the Company or
Indebtedness of a Restricted Subsidiary (in each case other than Indebtedness
owed to the Company or an Affiliate of the Company (other than an Affiliate of
Chase Capital Partners which is a lender in the ordinary course of business) and
other than obligations in respect of Disqualified Stock) within 180 days


                                                                              39

after the later of the date of such Asset Disposition or the receipt of such Net
Available Cash; (2) second, to the extent of the balance of Net Available Cash
                    ------
after application in accordance with clause (1), to the extent the Company or
such Restricted Subsidiary elects, to reinvest in Additional Assets (including
by means of an Investment in Additional Assets by a Restricted Subsidiary with
Net Available Cash received by the Company or another Restricted Subsidiary)
within 180 days from the later of such Asset Disposition or the receipt of such
Net Available Cash; (3) third, to the extent of the balance of such Net
                        -----
Available Cash after application in accordance with clauses (1) and (2), to make
an Offer (as defined in Section 4.06(b)) to purchase Securities pursuant to and
subject to the conditions of Section 4.06(b); provided, however, that if the
                                              --------  -------
Company elects (or is required by the terms of any Senior Subordinated
Indebtedness), such Offer may be made ratably to purchase the Securities and
other Senior Subordinated Indebtedness of the Company, and (4) fourth, to the
                                                               ------
extent of the balance of such Net Available Cash after application in accordance
with clauses (1), (2) and (3), for any general corporate purpose permitted by
the terms of this Indenture; provided, however, that in connection with any
                             --------  -------
final prepayment, repayment, purchase, repurchase, redemption, retirement,
defeasance or other acquisition for value of Indebtedness pursuant to clause
(1), (2) or (4) above, the Company or such Restricted Subsidiary shall retire
such Indebtedness and shall cause the related loan commitment (if any) to be
permanently reduced in an amount equal to the principal amount so prepaid,
repaid, purchased, repurchased, redeemed, retired, defeased or otherwise
acquired for value. Pending final application of any Net Available Cash in
accordance with the foregoing, the Company or a Restricted Subsidiary may use
such Net Available Cash to temporarily reduce (and, within such 180-day period,
reborrow) Indebtedness or invest such Net Available Cash in Temporary Cash
Equivalents. Notwithstanding the foregoing provisions of this Section 4.06, the
Company and the Restricted Subsidiaries shall not be required to apply any Net
Available Cash in accordance with this Section 4.06(a) except to the extent that
the aggregate Net Available Cash from all Asset Dispositions that is not applied
in accordance with this Section 4.06(a) exceeds $7.5 million.

          For the purposes of this Section 4.06, the following are deemed to be
cash:  (A) the assumption of Indebtedness of the Company (other than obligations
in respect of Disqualified Stock of the Company) or any Restricted Subsidiary
(other than obligations in respect of Disqualified Stock and Preferred Stock of
a Restricted Subsidiary that is not a Note Guarantor) and the release of the
Company or such Restricted Subsidiary from all liability on such Indebtedness in
connection with such Asset Disposition and (B) securities received by the
Company or any Restricted Subsidiary from the transferee that are promptly
converted by the Company or such Restricted Subsidiary into cash.

          (b)  In the event of an Asset Disposition that requires the purchase
of Securities pursuant to Section 4.06(a)(iii)(3), the Company shall be required
(i) to purchase Securities tendered pursuant to an offer by the Company for the
Securities (the "Offer") at a purchase price of 100% of their principal amount
plus accrued and unpaid interest and liquidated damages thereon, if any, to the
date of purchase (subject to the right of Holders of record on the relevant
record date to receive interest due on the relevant interest payment date) in
accordance with the procedures (including prorating in the event of
oversubscription) set forth in Section 4.06(c) and (ii) to purchase other Senior
Subordinated Indebtedness of the Company on the terms and to the


                                                                              40

extent contemplated thereby (provided that in no event shall the Company offer
to purchase such other Senior Subordinated Indebtedness of the Company at a
purchase price in excess of 100% of its principal amount (without premium), plus
accrued and unpaid interest thereon, unless an equal premium is offered to
Holders in the Offer). If the aggregate purchase price of Securities (and other
Senior Subordinated Indebtedness) tendered pursuant to the Offer is less than
the Net Available Cash allotted to the purchase of the Securities (and other
Senior Subordinated Indebtedness), the Company shall apply the remaining Net
Available Cash in accordance with Section 4.06(a)(iii)(4). The Company shall not
be required to make an Offer for Securities (and other Senior Subordinated
Indebtedness) pursuant to this Section 4.06 if the Net Available Cash available
therefor (after application of the proceeds as provided in clauses (1) and (2)
of Section 4.06(a)(iii)) is less than $5.0 million for any particular Asset
Disposition (which lesser amount shall be carried forward for purposes of
determining whether an Offer is required with respect to the Net Available Cash
from any subsequent Asset Disposition).

          (c)  (i)  Promptly, and in any event within 15 days after the Company
becomes obligated to make an Offer, the Company shall be obligated to deliver to
the Trustee and send, by first-class mail to each Holder, a written notice
stating that the Holder may elect to have his Securities purchased by the
Company either in whole or in part (subject to prorating as hereinafter
described in the event the Offer is oversubscribed) in integral multiples of
$1,000 of principal amount, at the applicable purchase price.  The notice shall
specify a purchase date not less than 30 days nor more than 60 days after the
date of such notice (the "Purchase Date") and shall contain such information
concerning the business of the Company which the Company in good faith believes
will enable such Holders to make an informed decision (which at a minimum shall
include (1) the most recently filed Annual Report on Form 10-K (including
audited consolidated financial statements) of the Company, the most recent
subsequently filed Quarterly Report on Form 10-Q and any Current Report on Form
8-K of the Company filed subsequent to such Quarterly Report, other than Current
Reports describing Asset Dispositions otherwise described in the offering
materials (or corresponding successor reports), (2) a description of material
developments in the Company's business subsequent to the date of the latest of
such reports, and (3) if material, appropriate pro forma financial information)
and all instructions and materials necessary to tender Securities pursuant to
the Offer, together with the address referred to in clause (iii).

          (ii) Not later than the date upon which written notice of an Offer is
delivered to the Trustee as provided above, the Company shall deliver to the
Trustee an Officers' Certificate as to (1) the amount of the Offer (the "Offer
Amount"), (2) the allocation of the Net Available Cash from the Asset
Dispositions pursuant to which such Offer is being made and (3) the compliance
of such allocation with the provisions of Section 4.06(a).  On such date, the
Company shall also irrevocably deposit with the Trustee or with a paying agent
(or, if the Company is acting as its own paying agent, segregate and hold in
trust) an amount equal to the Offer Amount to be invested in Temporary Cash
Investments (which Temporary Cash Investments will be made only pursuant to
written instructions of an officer of the Company) and to be held for payment in
accordance with the provisions of this Section.  Upon the expiration of the
period for which the Offer remains open (the "Offer Period"), the Company shall
deliver to the Trustee for cancelation the Securities or portions thereof that
have been properly tendered to


                                                                              41

and are to be accepted by the Company. The Trustee (or the Paying Agent, if not
the Trustee) shall, on the date of purchase, mail or deliver payment to each
tendering Holder in the amount of the purchase price. In the event that the
Offer Amount delivered by the Company to the Trustee is greater than the
purchase price of the Securities (and other Senior Subordinated Indebtedness)
tendered, the Trustee shall deliver the excess to the Company immediately after
the expiration of the Offer Period for application in accordance with this
Section 4.06.

          (iii) Holders electing to have a Security purchased shall be required
to surrender the Security, with an appropriate form duly completed (which form
shall include certain information concerning the Holder and the Security), to
the Company at the address specified in the notice at least three Business Days
prior to the Purchase Date. Holders shall be entitled to withdraw their election
if the Trustee or the Company receives not later than one Business Day prior to
the Purchase Date, a facsimile transmission or letter setting forth the name of
the Holder, the principal amount of the Security which was delivered by the
Holder for purchase and a duly signed statement that such Holder is withdrawing
his election to have such Security purchased. If at the expiration of the Offer
Period the aggregate principal amount of Securities and any other Senior
Subordinated Indebtedness included in the Offer surrendered by holders thereof
exceeds the Offer Amount, the Company shall select the Securities and other
Senior Subordinated Indebtedness to be purchased on a pro rata basis (with such
adjustments as may be deemed appropriate by the Company so that only Securities
and other Senior Subordinated Indebtedness in denominations of $1,000, or
integral multiples thereof, shall be purchased). Holders whose Securities are
purchased only in part will be issued new Securities equal in principal amount
to the unpurchased portion of the Securities surrendered.

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

          (v) The Company shall comply, to the extent applicable, with the
requirements of Section 14(e) of the Exchange Act and any other securities laws
or regulations in connection with the repurchase of Securities pursuant to this
Section 4.06. To the extent that the provisions of any securities laws or
regulations conflict with provisions of this Section 4.06, the Company shall
comply with the applicable securities laws and regulations and shall not be
deemed to have breached its obligations under this Section 4.06 by virtue
thereof.

          SECTION 4.07.  Limitation on Transactions with Affiliates.  (a)  The
                         -------------------------------------------
Company shall not, and shall not permit any Restricted Subsidiary to, directly
or indirectly, enter into or conduct any transaction or series of related
transactions (including the purchase, sale, lease or exchange of any property or
the rendering of any service) with any Affiliate of the Company (an "Affiliate
Transaction") unless such Affiliate Transaction is on terms (i) that are no less
favorable to the Company or such Restricted Subsidiary, as the case may be, than
those that could be obtained at the time of such transaction in arm's-length
dealings with a Person who is


                                                                              42

not such an Affiliate, (ii) that, in the event that such Affiliate Transaction

repurchase all or any part of such Holder's Securities at a purchase price in
cash equal to 101% of the principal amount thereof plus accrued and unpaid
interest and liquidated damages, if any, to the date of repurchase (subject to

contemplated in Section 4.08(b); provided, however, that notwithstanding the
                                 --------  -------
occurrence of a Change of Control, the Company shall not be obligated to
repurchase the Securities pursuant to this Section 4.08 in the event that it has
exercised its right to redeem all the Securities under paragraph 5 of the
Securities. In the event that at the time of such Change of Control the terms of
the Bank Indebtedness restrict or prohibit the repurchase of Securities pursuant
to this Section 4.08, then prior to the mailing of the notice to Holders
provided for in Section 4.08(b) below but in any event within 45 days following

accepted such offer or (ii) obtain the requisite consent under the agreements
governing the Bank Indebtedness to permit the repurchase of the Securities as
provided for in Section 4.08(b).

                                                                              43

          (b)   Within 45 days following any Change of Control (except as
provided in the proviso to the first sentence of Section 4.08(a)), the Company
shall mail a notice to each Holder with a copy to the Trustee (the "Change of
Control Offer") stating:

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

          (ii)  the circumstances and relevant facts and financial information
     regarding such Change of Control;

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

          (iv)  the instructions determined by the Company, consistent with this

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

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

          (e)   Notwithstanding the foregoing provisions of this Section, 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 4.08 applicable to a Change of Control Offer made by the Company and
purchases all Securities validly tendered and not withdrawn under such Change of
Control Offer.

          (f)   At the time the Company delivers Securities to the Trustee which
are to be accepted for purchase, the Company shall also deliver an Officers'
Certificate stating that such Securities are to be accepted by the Company
pursuant to and in accordance with the terms of this Section 4.08. A Security
shall be deemed to have been accepted for purchase at the time the


                                                                              44

requirements of Section 14(e) of the Exchange Act and any other securities laws
or regulations in connection with the repurchase of Securities pursuant to this
Section 4.08. To the extent that the provisions of any securities laws or
regulations conflict with provisions of this Section 4.08, the Company shall
comply with the applicable securities laws and regulations and shall not be
deemed to have breached its obligations under this Section 4.08 by virtue
thereof.

          SECTION 4.09.  Compliance Certificate.  The Company shall deliver to
                         -----------------------
the Trustee within 120 days after the end of each fiscal year of the Company an
Officers' Certificate stating that in the course of the performance by the
signers of their duties as Officers of the Company they would normally have
knowledge of any Default and whether or not the signers know of any Default that
occurred during such period. If they do, the certificate shall describe the
Default, its status and what action the Company is taking or proposes to take
with respect thereto. The Company also shall comply with Section 314(a)(4) of
the TIA.

          SECTION 4.10.  Further Instruments and Acts.  Upon request of the
                         -----------------------------
Trustee, the Company shall execute and deliver such further instruments and do
such further acts as may be reasonably necessary or proper to carry out more
effectively the purpose of this Indenture.

          SECTION 4.11.  Future Note Guarantors.  The Company shall cause (a)

Indebtedness (other than Indebtedness of a Restricted Subsidiary that is not a
Note Guarantor), to become a Note Guarantor, and if applicable, execute and
deliver to the Trustee a supplemental indenture substantially in the form of
Exhibit C pursuant to which such Subsidiary will Guarantee payment of the
Securities.

          SECTION 4.12.  Limitation on Lines of Business.  The Company shall
                         --------------------------------
not, and shall not permit any Restricted Subsidiary to, engage in any business,
other than a Permitted Business.

          SECTION 4.13.  Limitation on the Sale or Issuance of Capital Stock of
                         ------------------------------------------------------
Restricted Subsidiaries.  The Company shall not sell or otherwise dispose of any
- ------------------------
shares of Capital Stock (other than Preferred Stock that is not Voting Stock) of
a Restricted Subsidiary, and shall not permit any Restricted Subsidiary,
directly or indirectly, to issue or sell or otherwise dispose of any shares of
its Capital Stock (other than Preferred Stock that is not Voting Stock) except:
(a) to the Company or a Wholly Owned Subsidiary; (b) if, immediately after
giving effect to such issuance, sale or other disposition, neither the Company
nor any of its Subsidiaries own any Capital Stock of such Restricted Subsidiary
or (c) if, immediately after giving effect to such


                                                                              45

issuance or sale, such Restricted Subsidiary would no longer constitute a
Restricted Subsidiary and any Investment in such Person remaining after giving
effect thereto would have been permitted to be made under Section 4.04 if made
on the date of such issuance, sale or other disposition (and such Investment
shall be deemed to be an Investment made for purposes of such Section 4.04). The
proceeds of any sale of such Capital Stock subject to and permitted by this
Section 4.13 shall be treated as Net Available Cash from an Asset Disposition
and shall be applied in accordance with Section 4.06.

                             Defaults and Remedies
                             ---------------------

          SECTION 6.01. Events of Default.  An "Event of Default" occurs if:

     after receipt of the notice specified below;

          (f) Indebtedness of the Company or any Restricted Subsidiary is not
     paid within any applicable grace period after final maturity (and has not
     subsequently been paid) or the acceleration (which has not been rescinded)
     by the holders thereof because of a default and the total amount of such
     Indebtedness unpaid or accelerated exceeds $10.0 million or its foreign
     currency equivalent at the time and such failure continues for 10 days
     after receipt of the notice specified below;

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

               (i)   commences a voluntary case;

               (ii)  consents to the entry of an order for relief against it in

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

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

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

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

     indemnifications issued by or entered into with solvent Persons) in excess
     of $10.0 million or its foreign currency equivalent is rendered against the
     Company or any Restricted Subsidiary and either (i) an enforcement
     proceeding has been commenced by any creditor upon such judgment or decree

          (j) any Note Guarantee ceases to be in full force and effect (except
     as contemplated by the terms hereof) or any Note Guarantor or Person acting
     by or on behalf of such Note Guarantor denies or disaffirms its obligations
     under this Indenture or any Note Guarantee and such Default continues for
     10 days after receipt of the notice specified below.

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

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

          A Default under clause (d), (e), (f) or (j) above is not an Event of
Default until the Trustee notifies the Company or Holders of at least 25% in
principal amount of the outstanding Securities notify the Company and the
Trustee of the Default and the Company or the Note Guarantor, as applicable,
does not cure such Default within the time specified after receipt of such
notice. Such notice must specify the Default, demand that it be remedied and
state that such notice is a "Notice of Default".

          The Company shall deliver to a Responsible Officer of the Trustee,
within 30 days after the occurrence thereof, written notice in the form of an
Officers' Certificate of any event which with the giving of notice or the lapse
of time would become an Event of Default, its status and what action the Company
is taking or proposes to take with respect thereto.

          SECTION 6.02.  Acceleration.  If an Event of Default (other than an
                         -------------
Event of Default specified in Section 6.01(g) or (h) with respect to the
Company) occurs and is


                                                                              49

continuing, the Trustee by notice to the Company or the Holders of at least 25%
in principal amount of the outstanding Securities by notice to the Company and
the Trustee, may declare the principal of and accrued but unpaid interest on all
the Securities to be due and payable. Upon such a declaration, such principal
and interest shall be due and payable immediately. If an Event of Default
specified in Section 6.01(g) or (h) with respect to the Company occurs, the
principal of and interest on all the Securities shall ipso facto become and be
                                                      ---- -----
immediately due and payable without any declaration or other act on the part of
the Trustee or any Holders. The Holders of a majority in principal amount of the
Securities by notice to the Trustee may rescind an acceleration and its
consequences if the rescission would not conflict with any judgment or decree
and if all existing Events of Default have been cured or waived except
nonpayment of principal or interest that has become due solely because of
acceleration. No such rescission shall affect any subsequent Default or impair
any right consequent thereto.

          SECTION 6.03.  Other Remedies.  If an Event of Default occurs and is
                         ---------------
continuing, the Trustee may pursue any available remedy to collect the payment
of principal of or interest on the Securities or to enforce the performance of
any provision of the Securities or this Indenture.

          The Trustee may maintain a proceeding even if it does not possess any
of the Securities or does not produce any of them in the proceeding.  A delay or
omission by the Trustee or any Holder in exercising any right or remedy accruing
upon an Event of Default shall not impair the right or remedy or constitute a
waiver of or acquiescence in the Event of Default.  No remedy is exclusive of
any other remedy.  All available remedies are cumulative.

          SECTION 6.04.  Waiver of Past Defaults.  The Holders of a majority in
                         ------------------------
principal amount of the Securities by notice to the Trustee may waive an
existing Default and its consequences except (a) a Default in the payment of the
principal of or interest on a Security, (b) a Default arising from the failure
to redeem or purchase any Security when required pursuant to the terms of this
Indenture or (c) a Default in respect of a provision that under Section 9.02
cannot be amended without the consent of each Holder affected.  When a Default
is waived, it is deemed cured, but no such waiver shall extend to any subsequent
or other Default or impair any consequent right.

          SECTION 6.05.  Control by Majority.  The Holders of a majority in
                         --------------------
principal amount of the Securities may direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee or of
exercising any trust or power conferred on the Trustee.  However, the Trustee
may refuse to follow any direction that conflicts with law or this Indenture or,
subject to Section 7.01, that the Trustee determines is unduly prejudicial to
the rights of other Holders or would involve the Trustee in personal liability;
provided, however, that the Trustee may take any other action deemed proper by
- --------  -------
the Trustee that is not inconsistent with such direction.  Prior to taking any
action hereunder, the Trustee shall be entitled to indemnification satisfactory
to it in its sole discretion against all losses and expenses caused by taking or
not taking such action.


                                                                              50

          SECTION 6.06.  Limitation on Suits.  (a) Except to enforce the right
                         --------------------
to receive payment of principal, premium (if any) or interest when due, no
Holder may pursue any remedy with respect to this Indenture or the Securities
unless:

          (i)   the Holder gives to a Responsible Officer of the Trustee written
     notice stating that an Event of Default is continuing;

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

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

          SECTION 7.01.  Duties of Trustee.  (a)  If an Event of Default has
                         ------------------
occurred and is continuing, the Trustee shall exercise the rights and powers
vested in it by this Indenture and use the same degree of care and skill in
their exercise as a prudent person would exercise or use under the circumstances
in the conduct of such person's own affairs.

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

          (i)   the Trustee undertakes to perform such duties and only such
     duties as are specifically set forth in this Indenture and no implied
     covenants or obligations shall be read into this Indenture against the
     Trustee; and

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

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

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

          (ii)  the Trustee shall not be liable for any error of judgment made

          (iii) the Trustee shall not be liable with respect to any action it
     takes or omits to take in good faith in accordance with a direction

     expend or risk its own funds or otherwise incur financial liability in the
     performance of any of its duties hereunder or in the exercise of any of its
     rights or powers, if it shall have reasonable grounds to believe that
     repayment of such funds or adequate indemnity against such risk or
     liability is not reasonably assured to it.

          (d)   Every provision of this Indenture that in any way relates to the
Trustee is subject to paragraphs (a), (b) and (c) of this Section.


                                                                              53

                         ------------------

nominees and shall not be responsible for the misconduct or negligence of any
agent, attorney, custodian or nominee appointed with due care.

          (d)   The Trustee shall not be liable for any action it takes or omits
to take in good faith which it believes to be authorized or within its rights or
powers; provided, however, that the Trustee's conduct does not constitute wilful
        --------  -------
misconduct or negligence.

          (e)   The Trustee may consult with counsel of its selection, and the
advice or opinion of counsel with respect to legal matters relating to this
Indenture and the Securities shall be full and complete authorization and

                                                                              54

Paying Agent, Registrar or co-paying agent may do the same with like rights.
However, the Trustee must comply with Sections 7.10 and 7.11.

          SECTION 7.04.  Trustee's Disclaimer.  The Trustee shall not be
                         ---------------------
responsible for and makes no representation as to the validity or adequacy of
this Indenture, any Note Guarantee or the Securities, it shall not be
accountable for the Company's use of the proceeds from the Securities, and it
shall not be responsible for any statement of the Company or any Note Guarantor
in this Indenture or in any document issued in connection with the sale of the
Securities or in the Securities other than the Trustee's certificate of
authentication. The Trustee shall not be charged with knowledge of any Default
or Event of Default under Sections 6.01(c), (d), (e), (f), (i) or (j) or of the
identity of any Significant Subsidiary unless either (a) a Responsible Officer
shall have actual knowledge thereof or (b) a Responsible Officer of the Trustee
shall have received notice thereof in accordance with Section 13.02 hereof from
the Company, any Note Guarantor or any Holder.

          SECTION 7.05.  Notice of Defaults.   If a Default occurs and is
                         -------------------
continuing and, subject to Section 7.04 hereof, if it is actually known to a
Responsible Officer of the Trustee, the Trustee shall mail to each Holder notice
of the Default within the earlier of 90 days after it occurs or 30 days after it
is known to a Responsible Officer.  Except in the case of a Default in payment
of principal of or interest on any Security (including payments pursuant to the
redemption provisions of such Security, if any), 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 Holders.

          SECTION 7.06.  Reports by Trustee to Holders.  As promptly as
                         ------------------------------
practicable after each May 15 beginning with the May 15 following the date of
this Indenture, and in any event prior to July 15 in each year, the Trustee
shall mail to each Holder a brief report dated as of such May 15 that complies
with Section 313(a) of the TIA if and to the extent required thereby.  The
Trustee shall also comply with Section 313(b) of the TIA.

          A copy of each report at the time of its mailing to Holders shall be
filed with the SEC and each stock exchange (if any) on which the Securities are
listed. The Company agrees to notify promptly the Trustee whenever the
Securities become listed on any stock exchange and of any delisting thereof.

          SECTION 7.07.  Compensation and Indemnity.  The Company shall pay to
                         ---------------------------
the Trustee from time to time such compensation as shall be agreed to in writing
by the Company and the Trustee from time to time for its services.  The
Trustee's compensation shall not be limited by any law on compensation of a
trustee of an express trust.  The Company shall reimburse the Trustee upon
request for all reasonable out-of-pocket expenses incurred or made by it,
including costs of collection, in addition to the compensation for its services.
Such expenses shall include the reasonable compensation and expenses,
disbursements and advances of the Trustee's agents, counsel, accountants and
experts.  The Company and each Note Guarantor, jointly and severally shall
indemnify the Trustee against any and all loss, liability or expense (including
reasonable attorneys' fees and expenses) including taxes (other than taxes


                                                                              55

based upon, measured by or determined by the income of the Trustee) incurred by
or in connection with the administration of this trust and the performance of
its duties hereunder. The Trustee shall notify the Company of any claim for
which it may seek indemnity promptly upon obtaining actual knowledge thereof;
provided, however, that any failure so to notify the Company shall not relieve
- --------  -------
the Company or any Note Guarantor of its indemnity obligations hereunder. The
Company shall defend the claim and the indemnified party shall provide
reasonable cooperation at the Company's expense in the defense. Such indemnified
parties may have separate counsel and the Company and the Note Guarantors, as
applicable shall pay the fees and expenses of such counsel; provided, however,
                                                            --------  -------
that the Company shall not be required to pay such fees and expenses if it
assumes such indemnified parties' defense and, in such indemnified parties'
reasonable judgment, there is no conflict of interest between the Company and
the Note Guarantors, as applicable, and such parties in connection with such
defense. The Company need not reimburse any expense or indemnify against any
loss, liability or expense incurred by an indemnified party through such party's
own wilful misconduct, negligence or bad faith.

          To secure the Company's payment obligations in this Section, the
Trustee shall have a lien prior to the Securities on all money or property held
or collected by the Trustee other than money or property held in trust to pay
principal of and interest and liquidated damages, if any, on particular
Securities.

          The Company's payment obligations pursuant to this Section shall
survive the satisfaction or discharge of this Indenture, any rejection or
termination of this Indenture under any bankruptcy law or the resignation or
removal of the Trustee.  Without prejudice to any other rights available to the
Trustee under applicable law, when the Trustee incurs expenses after the
occurrence of a Default specified in Section 6.01(g) or (h) with respect to the
Company, the expenses are intended to constitute expenses of administration
under the Bankruptcy Law.

any time by so notifying the Company.  The Holders of a majority in principal
amount of the Securities may remove the Trustee by so notifying the Trustee and
may appoint a successor Trustee.  The Company shall remove the Trustee if:

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

          (ii)  the Trustee is adjudged bankrupt or insolvent;

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

          (iv)  the Trustee otherwise becomes incapable of acting.

          (b)   If the Trustee resigns, is removed by the Company or by the
Holders of a majority in principal amount of the Securities and such Holders do
not reasonably promptly appoint a successor Trustee, or if a vacancy exists in
the office of Trustee for any reason (the


                                                                              56

Trustee in such event being referred to herein as the retiring Trustee), the
Company shall promptly appoint a successor Trustee.

          (c) A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company.  Thereupon the
resignation or removal of the retiring Trustee shall become effective only upon
receipt of charges due to the Resigning Trustee, and the successor Trustee shall
have all the rights, powers and duties of the Trustee under this Indenture. The
successor Trustee shall mail a notice of its succession to Holders. The retiring
Trustee shall promptly transfer all property held by it as Trustee to the
successor Trustee, subject to the lien provided for in Section 7.07.

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

          (e) If the Trustee fails to comply with Section 7.10, unless the
Trustee's duty to resign is stayed as provided in TIA '310(b), any Holder who
has been a bona fide holder of a Security for at least six months may petition
any court of competent jurisdiction for the removal of the Trustee and the
appointment of a successor Trustee.

          (f) Notwithstanding the replacement of the Trustee pursuant to this
Section, the Company's obligations under Section 7.07 shall continue for the
benefit of the retiring Trustee.

          (g) If an instrument of acceptance by a successor Trustee shall not
have been delivered to the Trustee within 60 days after the giving of such
notice of resignation or removal, the resigning or removed Trustee, as the case
may be, may petition, at the expense of the Company, any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the
Securities.

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

          In case at the time such successor or successors by merger, conversion
or consolidation to the Trustee shall succeed to the trusts created by this
Indenture any of the Securities shall have been authenticated but not delivered,
any such successor to the Trustee may adopt the certificate of authentication of
any predecessor trustee, and deliver such Securities so authenticated; and in
case at that time any of the Securities shall not have been authenticated, any
successor to the Trustee may authenticate such Securities either in the name of
any predecessor hereunder or in the name of the successor to the Trustee; and in
all such cases such certificates shall have the full force which it is anywhere
in the Securities or in this Indenture provided that the certificate of the
Trustee shall have.


                                                                              57

          SECTION 7.10.  Eligibility; Disqualification.  The Trustee shall at
                         ------------------------------
all times satisfy the requirements of TIA ' 310(a).  The Trustee shall have a
combined capital and surplus of at least $50,000,000 as set forth in its most
recent published annual report of condition.  The Trustee shall comply with TIA
' 310(b), subject to its right to apply for a stay of its duty to resign under
the penultimate paragraph of TIA '310(b); provided, however, that there shall be
                                          --------  -------
excluded from the operation of TIA ' 310(b)(1) any indenture or indentures under
which other securities or certificates of interest or participation in other
securities of the Company are outstanding if the requirements for such exclusion
set forth in TIA ' 310(b)(1) are met.

          SECTION 7.11.  Preferential Collection of Claims Against Company.  The
                         --------------------------------------------------
Trustee shall comply with TIA ' 311(a), excluding any creditor relationship
listed in TIA ' 311(b).  A Trustee who has resigned or been removed shall be
subject to TIA ' 311(a) to the extent indicated.

          SECTION 7.12.  Investment of Funds.  In the event of a loss on the
                         --------------------
sale of any Temporary Cash Investments purchased at the direction of the Company
(after giving effect to any interest or other income thereon except to the
extent theretofore paid to the Company), the Trustee shall have no
responsibility in respect of such loss except that the Trustee shall notify the
Company of the amount of such loss and the Company shall promptly pay such
amount to the Trustee to be credited as part of the moneys originally invested.

          SECTION 8.01.  Discharge of Liability on Securities; Defeasance.  (a)
                         -------------------------------------------------
When (i) all outstanding Securities (other than Securities replaced or paid
pursuant to Section 2.07) have been canceled or delivered to the Trustee for
cancelation or (ii) all outstanding Securities have become due and payable,
whether at maturity or as a result of the mailing of a notice of redemption
pursuant to Article 3 hereof, and the Company irrevocably deposits with the
Trustee funds in an amount sufficient or U.S. Government Obligations, the
principal of and interest on which will be sufficient, or a combination thereof
sufficient, in the written opinion of a nationally recognized firm of
independent public accountants delivered to the Trustee (which delivery shall
only be required if U.S. Government Obligations have been so deposited) to pay
the principal of and interest on the outstanding Securities when due at maturity
or upon redemption of, including interest thereon to maturity or such redemption
date (other than Securities replaced or paid pursuant to Section 2.07) and
liquidated damages, if any, and if in either case the Company pays all other
sums payable hereunder by the Company, then this Indenture shall, subject to
Section 8.01(c), cease to be of further effect. The Trustee shall acknowledge
satisfaction and discharge of this Indenture on demand of the Company
accompanied by an Officers' Certificate and an Opinion of Counsel and at the
cost and expense of the Company.


                                                                              58

          (b)  Subject to Sections 8.01(c) and 8.02, the Company at any time may
terminate (i) all of its obligations under the Securities and this Indenture
("legal defeasance option") or (ii) its obligations under Sections 4.02, 4.03,
4.04, 4.05, 4.06, 4.07, 4.08, 4.11, 4.12 and 4.13, and the operation of Section
5.01(a)(iii), 6.01(d), 6.01(f), 6.01(g) (with respect to Significant
Subsidiaries of the Company only), 6.01(h) (with respect to Significant
Subsidiaries of the Company only) and 6.01(i) ("covenant defeasance option").
The Company may exercise its legal defeasance option notwithstanding its prior
exercise of its covenant defeasance option.  In the event that the Company
terminates all of its obligations under the Securities and this Indenture by
exercising its legal defeasance option or its covenant defeasance option, the
obligations under the Note Guarantees shall each be terminated simultaneously
with the termination of such obligations.

          If the Company exercises its legal defeasance option, payment of the
Securities may not be accelerated because of an Event of Default.  If the
Company exercises its covenant defeasance option, payment of the Securities may
not be accelerated because of an Event of Default specified in Section 6.01(d),
6.01(f), 6.01(g),  (with respect to Significant Subsidiaries of the Company
only), 6.01(h) (with respect to Significant Subsidiaries of the Company only) or
6.01(i) or because of the failure of the Company to comply with clause (iii) of
Section 5.01(a).

          Upon satisfaction of the conditions set forth herein and upon request
of the Company, the Trustee shall acknowledge in writing the discharge of those
obligations that the Company terminates.

          (c)  Notwithstanding clauses (a) and (b) above, the Company's
obligations in Sections 2.03, 2.04, 2.05, 2.06, 2.07, 2.08, 7.07, 7.08 and in
this Article 8 shall survive until the Securities have been paid in full.
Thereafter, the Company's obligations in Sections 7.07, 8.04 and 8.05 shall
survive.

          SECTION 8.02.  (a)  Conditions to Defeasance.  The Company may
                              -------------------------
exercise its legal defeasance option or its covenant defeasance option only if:

          (i)  the Company irrevocably deposits in trust with the Trustee money
     in an amount sufficient or U.S. Government Obligations, the principal of
     and interest on which will be sufficient, or a combination thereof
     sufficient, to pay the principal, premium (if any) and interest on the
     Securities when due at maturity or redemption, as the case may be,
     including interest thereon to maturity or such redemption date and
     liquidated damages, if any;

          (ii) the Company delivers to the Trustee a certificate from a
     nationally recognized firm of independent accountants expressing their
     opinion that the payments of principal and interest when due and without
     reinvestment on the deposited U.S. Government Obligations plus any
     deposited money without investment will provide cash at such times and in
     such amounts as will be sufficient to pay principal and interest when due
     on all the Securities to maturity or redemption, as the case may be;


                                                                              59

          (iii) 123 days pass after the deposit is made and during the 123-day
     period no Default specified in Section 6.01(g) or (h) with respect to the
     Company occurs which is continuing at the end of the period;

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

          (v)    the Company delivers to the Trustee an Opinion of Counsel
     reasonably acceptable to the Trustee to the effect that the trust resulting
     from the deposit does not constitute, or is qualified as, a regulated
     investment company under the Investment Company Act of 1940;

          (vi)   in the case of the legal defeasance option, the Company shall
     have delivered to the Trustee an Opinion of Counsel reasonably acceptable
     to the Trustee stating that (1) the Company has received from, or there has
     been published by, the Internal Revenue Service a ruling, or (2) since the
     date of this Indenture there has been a change in the applicable Federal
     income tax law, in either case to the effect that, and based thereon such
     Opinion of Counsel shall confirm that, the Holders will not recognize
     income, gain or loss for Federal income tax purposes as a result of such
     defeasance and will be subject to Federal income tax on the same amounts,
     in the same manner and at the same times as would have been the case if
     such defeasance had not occurred;

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

          (viii) the Company delivers to the Trustee an Officers' Certificate
     and an Opinion of Counsel, each stating that all conditions precedent to
     the defeasance and discharge of the Securities as contemplated by this
     Article 8 have been complied with.

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

          SECTION 8.03.  Application of Trust Money.  The Trustee shall hold in
                         ---------------------------
trust money or U.S. Government Obligations deposited with it pursuant to this
Article 8. It shall apply the deposited money and the money from U.S. Government
Obligations through the Paying Agent and in accordance with this Indenture to
the payment of principal of and interest on the Securities. Money and securities
so held in trust are not subject to Article 10 or 12.

          SECTION 8.04.  Repayment to Company.  The Trustee and the Paying Agent
                         ---------------------
shall promptly turn over to the Company upon request any money or U.S.
Government Obligations held by it as provided in this Article which, in the
written opinion of nationally


                                                                              60

recognized firm of independent public accountants delivered to the Trustee
(which delivery shall only be required if U.S. Government Obligations have been
so deposited), are in excess of the amount thereof which would then be required
to be deposited to effect an equivalent discharge or defeasance in accordance
with this Article.

          Subject to any applicable abandoned property law, the Trustee and the
Paying Agent shall pay to the Company upon written request any money held by
them for the payment of principal or interest that remains unclaimed for two
years, and, thereafter, Holders entitled to the money must look to the Company
for payment as general creditors and the Trustee, and the Paying Agent shall
have no further liability with respect to such monies.

          SECTION 8.05.  Indemnity for Government Obligations.  The Company
                         -------------------------------------
shall pay and shall indemnify the Trustee against any tax, fee or other charge
imposed on or assessed against deposited U.S. Government Obligations or the
principal and interest received on such U.S. Government Obligations.

          SECTION 8.06.  Reinstatement.  If the Trustee or Paying Agent is
                         --------------
unable to apply any money or U.S. Government Obligations in accordance with this
Article 8 by reason of any legal proceeding or by reason of any order or
judgment of any court or governmental authority enjoining, restraining or
otherwise prohibiting such application, the Company's obligations under this
Indenture and the Securities shall be revived and reinstated as though no
deposit had occurred pursuant to this Article 8 until such time as the Trustee
or Paying Agent is permitted to apply all such money or U.S. Government
Obligations in accordance with this Article 8;  provided, however, that, if the
                                               ---------  -------
Company has made any payment of interest on or principal of any Securities
because of the reinstatement of its obligations, the Company shall be subrogated
to the rights of the Holders of such Securities to receive such payment from the
money or U.S. Government Obligations held by the Trustee or Paying Agent.


                                   ARTICLE 9

                                  Amendments
                                  ----------

          SECTION 9.01.  (a)  Without Consent of Holders.  The Company, the Note
                              ---------------------------
Guarantors and the Trustee may amend this Indenture or the Securities without
notice to or consent of any Holder:

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

          (ii)  to comply with Article 5;

          (iii) to provide for uncertificated Securities in addition to or in
     place of certificated Securities; provided, however, that the
                                       --------  -------
     uncertificated Securities are issued in registered form for purposes of
     Section 163(f) of the Code or in a manner such that the uncertificated
     Securities are described in Section 163(f)(2)(B) of the Code;


                                                                              61


          (iv)    to make any change in Article 10 or Article 12 that would
     limit or terminate the benefits available to any holder of Senior
     Indebtedness (or representatives thereof) under Article 10 or Article 12;

          (v)     to add additional Guarantees with respect to the Securities or
     to secure the Securities;

          (vi)    to add to the covenants of the Company for the benefit of the
     Holders or to surrender any right or power herein conferred upon the
     Company;

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

          (viii)  to make any change that does not adversely affect the rights
     of any Holder in a material respect; or

          (ix)    to provide for the issuance of the Exchange Securities or
     Private Exchange Securities, which shall have terms substantially identical
     in all material respects to the Initial Securities (except that the
     transfer restrictions contained in the Initial Securities shall be modified
     or eliminated, as appropriate), and which shall be treated, together with
     any outstanding Initial Securities, as a single issue of securities.

          (b)  An amendment under this Section 9.01 may not make any change to
Article 10 or Article 12 that adversely affects the rights under Article 10 or
Article 12 of any holder of Senior Indebtedness then outstanding unless the
holders of such Senior Indebtedness (or any group or representative thereof
authorized to give a consent) consent to such change.

          After an amendment under this Section 9.01 becomes effective, the
Company shall mail to Holders a notice briefly describing such amendment.  The
failure to give such notice to all Holders, or any defect therein, shall not
impair or affect the validity of an amendment under this Section.

          SECTION 9.02.  With Consent of Holders.  (a)  The Company, the Note
                         ------------------------
Guarantors and the Trustee may amend this Indenture or the Securities without
notice to any Holder but with the written consent of the Holders of at least a
majority in principal amount of the Securities then outstanding (including
consents obtained in connection with a tender offer or exchange for the
Securities).  However, without the consent of each Holder affected, an amendment
may not:

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

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


                                                                              62

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

          (iv)   reduce the premium payable upon the redemption of any Security
     or accelerate the time at which any Security may be redeemed;

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

          (vi)   make any change in Article 10 or Article 12 that adversely
     affects the rights of any Holder under Article 10 or Article 12;

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

          (viii) modify the Note Guarantees in any manner adverse to the Holders
     in a material respect.

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

          An amendment under this Section 9.02 may not make any change that
adversely affects the rights under Article 10 or Article 12 of any holder of
Senior Indebtedness then outstanding unless the holders of such Senior
Indebtedness (or any group or representative thereof authorized to give a
consent) consent to such change.

          After an amendment under this Section 9.02 becomes effective, the
Company shall mail to Holders a notice briefly describing such amendment.  The
failure to give such notice to all Holders, or any defect therein, shall not
impair or affect the validity of an amendment under this Section 9.02.

          SECTION 9.03.  Compliance with Trust Indenture Act.  Every amendment
                         ------------------------------------
to this Indenture or the Securities shall comply with the TIA as then in effect.

          SECTION 9.04.  Revocation and Effect of Consents and Waivers.  (a) A
                         ----------------------------------------------
consent to an amendment or a waiver by a Holder of a Security shall bind the
Holder and every subsequent Holder of that Security or portion of the Security
that evidences the same debt as the consenting Holder's Security, even if
notation of the consent or waiver is not made on the Security.  However, any
such Holder or subsequent Holder may revoke the consent or waiver as to such
Holder's Security or portion of the Security if the Trustee receives the notice
of revocation before the date on which the Trustee receives an Officers'
Certificate from the Company certifying that the requisite number of consents
have been received.  After an amendment or waiver becomes effective, it shall
bind every Holder.  An amendment or waiver becomes effective upon the (i)
receipt by the Company or the Trustee of the requisite number of consents, (ii)
satisfaction of conditions to effectiveness as set forth in this Indenture and
any


                                                                              63

indenture supplemental hereto containing such amendment or waiver and (iii)
execution of such amendment or waiver (or supplemental indenture) by the Company
and the Trustee.

          (b)  The Company may, but shall not be obligated to, fix a record date
for the purpose of determining the Holders entitled to give their consent or
take any other action described above or required or permitted to be taken
pursuant to this Indenture.  If a record date is fixed, then notwithstanding the
immediately preceding paragraph, those Persons who were Holders at such record
date (or their duly designated proxies), and only those Persons, shall be
entitled to give such consent or to revoke any consent previously given or to
take any such action, whether or not such Persons continue to be Holders after
such record date.  No such consent shall be valid or effective for more than 120
days after such record date.

          SECTION 9.05.  Notation on or Exchange of Securities.  If an amendment
                         --------------------------------------
changes the terms of a Security, the Trustee may require the Holder of the
Security to deliver it to the Trustee.  The Trustee may place an appropriate
notation on the Security regarding the changed terms and return it to the
Holder.  Alternatively, if the Company or the Trustee so determines, the Company
in exchange for the Security shall issue and the Trustee shall authenticate a
new Security that reflects the changed terms.  Failure to make the appropriate
notation or to issue a new Security shall not affect the validity of such
amendment.

          SECTION 9.06.  Trustee to Sign Amendments.  The Trustee shall sign any
                         ---------------------------
amendment authorized pursuant to this Article 9 if the amendment does not
adversely affect the rights, duties, liabilities or immunities of the Trustee.
If it does, the Trustee may but need not sign it.  In signing such amendment the
Trustee shall receive indemnity reasonably satisfactory to it and to receive,
and (subject to Section 7.01) shall be fully protected in relying upon, an
Officers' Certificate and an Opinion of Counsel stating that such amendment is
authorized or permitted by this Indenture and that such amendment is the legal,
valid and binding obligation of the Company and the Note Guarantors enforceable
against them in accordance with its terms, subject to customary exceptions, and
complies with the provisions hereof (including Section 9.03).


                                  ARTICLE 10

                                 Subordination
                                 -------------

          SECTION 10.01.  Agreement To Subordinate.  The Company agrees, and
                          -------------------------
each Holder by accepting a Security agrees, that the Indebtedness evidenced by
the Securities is subordinated in right of payment, to the extent and in the
manner provided in this Article 10, to the prior payment in full of all Senior
Indebtedness of the Company and that the subordination is for the benefit of and
enforceable by the holders of such Senior Indebtedness.  The Securities shall in
all respects rank pari passu with all other Senior Subordinated Indebtedness of
                  ---- -----
the Company and only Indebtedness of the Company that is Senior Indebtedness of
the Company shall rank senior to the Securities in accordance with the
provisions set forth herein.  For purposes of this Article 10, the Indebtedness
evidenced by the Securities shall be deemed to


                                                                              64

include any liquidated damages payable pursuant to the provisions set forth in
the Securities and the Registration Agreement. All provisions of this Article 10
shall be subject to Section 10.12.

          SECTION 10.02.  Liquidation, Dissolution, Bankruptcy.  Upon any
                          -------------------------------------
payment or distribution of the assets of the Company to creditors upon a
liquidation or a dissolution of the Company or in a bankruptcy, reorganization,
insolvency, receivership or similar proceeding relating to the Company or its
property:

          (a) holders of Senior Indebtedness of the Company shall be entitled to
     receive payment in full  of such Senior Indebtedness before Holders shall
     be entitled to receive any payment of principal of or interest on the
     Securities; and

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

          SECTION 10.03.  Default on Senior Indebtedness.  The Company may not
                          -------------------------------
pay the principal of, premium (if any) or interest on the Securities or make any
deposit pursuant to Section 8.01 and may not otherwise repurchase, redeem or
otherwise acquire or retire for value any Securities (collectively, "pay the
Securities") if (a) any Designated Senior Indebtedness of the Company is not
paid when due or (b) any other default on any Designated Senior Indebtedness of
the Company occurs and the maturity of such Designated Senior Indebtedness is
accelerated in accordance with its terms unless, in either case, (i) the default
has been cured or waived and any such acceleration has been rescinded or (ii)
such Designated Senior Indebtedness has been paid in full; provided, however,
                                                           --------  -------
that the Company may pay the Securities without regard to the foregoing if the
Company and a Responsible Officer of the Trustee receive written notice
approving such payment from the Representative of such Designated Senior
Indebtedness with respect to which either of the events set forth in clause (a)
or (b) of this sentence has occurred and is continuing.  During the continuance
of any default (other than a default described in clause (a) or (b) of the
preceding sentence) with respect to any Designated Senior Indebtedness of the
Company pursuant to which the maturity thereof may be accelerated immediately
without further notice (except such notice as may be required to effect such
acceleration) or the expiration of any applicable grace periods, the Company may
not pay the Securities for a period (a "Payment Blockage Period") commencing
upon the receipt by a Responsible Officer of the Trustee (with a copy to the
Company) of written notice (a "Blockage Notice") of such default from the
Representative of such Designated Senior Indebtedness specifying an election to
effect a Payment Blockage Period and ending 179 days thereafter (or earlier if
such Payment Blockage Period is terminated (a) by written notice to the Trustee
and the Company from the Person or Persons who gave such Blockage Notice, (b) by
repayment in full of such Designated Senior Indebtedness or (c) because the
default giving rise to such Blockage Notice is no longer continuing).
Notwithstanding the provisions described in the immediately preceding sentence
(but subject to the provisions contained in the second preceding and in the
immediately succeeding sentence), unless the holders of such Designated Senior
Indebtedness or


                                                                              65

the Representative of such holders shall have accelerated the maturity of such
Designated Senior Indebtedness, the Company may resume payments on the
Securities after the end of such Payment Blockage Period, including any missed
payments. Not more than one Blockage Notice may be given in any consecutive 360-
day period, irrespective of the number of defaults with respect to Designated
Senior Indebtedness during such period; provided, however, that if any Blockage
                                        --------  -------
Notice within such 360-day period is given by or on behalf of any holders of
Designated Senior Indebtedness other than the Bank Indebtedness, the
Representative of the Bank Indebtedness may give another Blockage Notice within
such period; provided further, however, that in no event may the total number of
             ----------------  -------
days during which any Payment Blockage Period or Periods is in effect exceed 179
days in the aggregate during any 360 consecutive day period.  For purposes of
this Section 10.03, no default or event of default that existed or was
continuing on the date of the commencement of any Payment Blockage Period with
respect to the Designated Senior Indebtedness initiating such Payment Blockage
Period shall be, or be made, the basis of the commencement of a subsequent
Payment Blockage Period by the Representative of such Designated Senior
Indebtedness, whether or not within a period of 360 consecutive days, unless
such default or event of default shall have been cured or waived for a period of
not less than 90 consecutive days.

          SECTION 10.04.  Acceleration of Payment of Securities.  If payment of
                          --------------------------------------
the Securities is accelerated because of an Event of Default, the Company or the
Trustee (provided, that the Trustee shall have received written notice from the
         --------
Company, on which notice the Trustee shall be entitled to conclusively rely)
shall promptly notify the holders of the Designated Senior Indebtedness of the
Company (or their Representative) of the acceleration.  If any Designated Senior
Indebtedness of the Company is outstanding, the Company may not pay the
Securities until five Business Days after such holders or the Representative of
such Designated Senior Indebtedness receive notice of such acceleration and,
thereafter, may pay the Securities only if this Article 10 otherwise permits
payment at that time.

          SECTION 10.05.  When Distribution Must Be Paid Over.  If a payment or
                          ------------------------------------
distribution is made to Holders that because of this Article 10 should not have
been made to them, the Holders who receive the payment or distribution shall
hold it in trust for holders of Senior Indebtedness of the Company and pay it
over to them as their interests may appear.

          SECTION 10.06.  Subrogation.  After all Senior Indebtedness of the
                          ------------
Company is paid in full and until the Securities are paid in full, Holders shall
be subrogated to the rights of holders of such Senior Indebtedness to receive
distributions applicable to Senior Indebtedness.  A distribution made under this
Article 10 to holders of such Senior Indebtedness which otherwise would have
been made to Holders is not, as between the Company and Holders, a payment by
the Company on such Senior Indebtedness.

          SECTION 10.07.  Relative Rights.  This Article 10 defines the relative
                          ----------------
rights of Holders and holders of Senior Indebtedness of the Company.  Nothing in
this Indenture shall:


                                                                              66

          (a) impair, as between the Company and Holders, the obligation of the
     Company, which is absolute and unconditional, to pay principal of and
     interest on and liquidated damages, if any, in respect of, the Securities
     in accordance with their terms; or

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

          SECTION 10.08.  Subordination May Not Be Impaired by Company.  No
                          ---------------------------------------------
right of any holder of Senior Indebtedness of the Company to enforce the
subordination of the Indebtedness evidenced by the Securities shall be impaired
by any act or failure to act by the Company or by its failure to comply with
this Indenture.

          SECTION 10.09.  Rights of Trustee and Paying Agent.  Notwithstanding
                          -----------------------------------
Section 10.03, the Trustee or Paying Agent may continue to make payments on the
Securities and shall not be charged with knowledge of the existence of facts
that would prohibit the making of any such payments unless, not less than two
Business Days prior to the date of such payment, a Responsible Officer of the
Trustee receives notice satisfactory to it that payments may not be made under
this Article 10.  The Company, the Registrar, the Paying Agent, a Representative
or a holder of Senior Indebtedness of the Company may give the notice; provided,
                                                                       --------
however, that, if an issue of Senior Indebtedness of the Company has a
- -------
Representative, only the Representative may give the notice.

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

          SECTION 10.10.  Distribution or Notice to Representative.  Whenever a
                          -----------------------------------------
distribution is to be made or a notice given to holders of Senior Indebtedness
of the Company, the distribution may be made and the notice given to their
Representative (if any).

          SECTION 10.11.  Article 10 Not To Prevent Events of Default or Limit
                          ----------------------------------------------------
Right To Accelerate.  The failure to make a payment pursuant to the Securities
- --------------------
by reason of any provision in this Article 10 shall not be construed as
preventing the occurrence of a Default.  Nothing in this Article 10 shall have
any effect on the right of the Holders or the Trustee to accelerate the maturity
of the Securities.

          SECTION 10.12.  Trust Monies Not Subordinated.  Notwithstanding
                          ------------------------------
anything contained herein to the contrary, payments from money or the proceeds
of U.S. Government Obligations held in trust under Article 8 by the Trustee for
the payment of principal of and


                                                                              67

interest on the Securities and liquidated damages, if any, shall not be
subordinated to the prior payment of any Senior Indebtedness of the Company or
subject to the restrictions set forth in this Article 10, and none of the
Holders shall be obligated to pay over any such amount to the Company or any
holder of Senior Indebtedness of the Company or any other creditor of the
Company.

          SECTION 10.13.  Trustee Entitled To Rely.  Upon any payment or
                          -------------------------
distribution pursuant to this Article 10, the Trustee and the Holders shall be
entitled to rely conclusively (a) upon any order or decree of a court of
competent jurisdiction in which any proceedings of the nature referred to in
Section 10.02 are pending, (b) upon a certificate of the liquidating trustee or
agent or other Person making such payment or distribution to the Trustee or to
the Holders or (c) upon the Representatives for the holders of Senior
Indebtedness of the Company for the purpose of ascertaining the Persons entitled
to participate in such payment or distribution, the holders of such Senior
Indebtedness and other Indebtedness of the Company, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts pertinent thereto or to this Article 10.  In the event that the Trustee
determines, in good faith, that evidence is required with respect to the right
of any Person as a holder of Senior Indebtedness of the Company to participate
in any payment or distribution pursuant to this Article 10, the Trustee may
request such Person to furnish evidence to the reasonable satisfaction of the
Trustee as to the amount of such Senior Indebtedness held by such Person, the
extent to which such Person is entitled to participate in such payment or
distribution and other facts pertinent to the rights of such Person under this
Article 10, and, if such evidence is not furnished, the Trustee may defer any
payment to such Person pending judicial determination as to the right of such
Person to receive such payment.  The provisions of Sections 7.01 and 7.02 shall
be applicable to all actions or omissions of actions by the Trustee pursuant to
this Article 10.

          SECTION 10.14.  Trustee To Effectuate Subordination.  Each Holder by
                          ------------------------------------
accepting a Security authorizes and directs the Trustee on his behalf to take
such action as may be necessary or appropriate to acknowledge or effectuate the
subordination between the Holders and the holders of Senior Indebtedness of the
Company as provided in this Article 10 and appoints the Trustee as attorney-in-
fact for any and all such purposes.

          SECTION 10.15.  Trustee Not Fiduciary for Holders of Senior
                          -------------------------------------------
Indebtedness.  The Trustee shall not be deemed to owe any fiduciary duty to the
- -------------
holders of Senior Indebtedness of the Company and shall not be liable to any
such holders if it shall mistakenly pay over or distribute to Holders or the
Company or any other Person, money or assets to which any holders of Senior
Indebtedness of the Company shall be entitled by virtue of this Article 10 or
otherwise.

          SECTION 10.16.  Reliance by Holders of Senior Indebtedness on
                          ---------------------------------------------
Subordination Provisions.  Each Holder by accepting a Security acknowledges and
- -------------------------
agrees that the foregoing subordination provisions are, and are intended to be,
an inducement and a consideration to each holder of any Senior Indebtedness of
the Company, whether such Senior Indebtedness was created or acquired before or
after the issuance of the Securities, to acquire and continue to hold, or to
continue to hold, such Senior Indebtedness and such holder of such Senior
Indebtedness


                                                                              68

shall be deemed conclusively to have relied on such subordination provisions in
acquiring and continuing to hold, or in continuing to hold, such Senior
Indebtedness.

                                  ARTICLE 11

                                Note Guarantees
                                ---------------

          SECTION 11.01.  (a) Note Guarantees.  Each Note Guarantor hereby
                              ----------------
jointly and severally irrevocably and unconditionally guarantees, as a primary
obligor and not merely as a surety, to each Holder and to the Trustee and its
successors and assigns (i) the full and punctual payment when due, whether at
Stated Maturity, by acceleration, by redemption or otherwise, of all obligations
of the Company under this Indenture (including obligations to the Trustee) and
the Securities, whether for payment of principal of, interest on or liquidated
damages, if any, in respect of the Securities and all other monetary obligations
of the Company under this Indenture and the Securities and (ii) the full and
punctual performance within applicable grace periods of all other monetary
obligations of the Company whether for fees, expenses, indemnification or
otherwise under this Indenture and the Securities (all the foregoing being
hereinafter collectively called the "Guaranteed Obligations").  Each Note
Guarantor further agrees that the Guaranteed Obligations may be extended or
renewed, in whole or in part, without notice or further assent from each such
Note Guarantor, and that each such Note Guarantor shall remain bound under this
Article 11 notwithstanding any extension or renewal of any Guaranteed
Obligation.

          (b)  Each Note Guarantor waives presentation to, demand of payment
from and protest to the Company of any of the Guaranteed Obligations and also
waives notice of protest for nonpayment.  Each Note Guarantor waives notice of
any default under the Securities or the Guaranteed Obligations.  The obligations
of each Note Guarantor hereunder shall not be affected by (i) the failure of any
Holder or the Trustee to assert any claim or demand or to enforce any right or
remedy against the Company or any other Person under this Indenture, the
Securities or any other agreement or otherwise; (ii) any extension or renewal of
any thereof; (iii) any rescission, waiver, amendment or modification of any of
the terms or provisions of this Indenture, the Securities or any other agreement
except to the extent such rescission, waiver, amendment or modification
explicitly relates to such Note Guarantor's obligations hereunder; (iv) the
release of any security held by any Holder or the Trustee for the Guaranteed
Obligations or any of them; (v) the failure of any Holder or Trustee to exercise
any right or remedy against any other guarantor of the Guaranteed Obligations;
or (vi) any change in the ownership of such Note Guarantor, except as provided
in Section 11.02(b).

          (c)  Each Note Guarantor hereby waives any right to which it may be
entitled to have its obligations hereunder divided among the Note Guarantors,
such that such Note Guarantor's obligations would be less than the full amount
claimed.  Each Note Guarantor hereby waives any right to which it may be
entitled to have the assets of the Company first be used and depleted as payment
of the Company's or such Note Guarantor's obligations hereunder prior to any
amounts being claimed from or paid by such Note Guarantor hereunder.  Each Note


                                                                              69

Guarantor hereby waives any right to which it may be entitled to require that
the Company be sued prior to an action being initiated against such Note
Guarantor.

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

          (e)  The Note Guarantee of each Note Guarantor is, to the extent and
in the manner set forth in Article 12, subordinated and subject in right of
payment to the prior payment in full  of the principal of and premium, if any,
and interest on all Senior Indebtedness of the relevant Note Guarantor and is
made subject to such provisions of this Indenture.

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

          (g)  Each Note Guarantor agrees that its Note Guarantee shall remain
in full force and effect until payment in full of all the Guaranteed
Obligations.  Each Note Guarantor further agrees that its Note Guarantee herein
shall continue to be effective or be reinstated, as the case may be, if at any
time payment, or any part thereof, of principal of or interest on any Guaranteed
Obligation is rescinded or must otherwise be restored by any Holder or the
Trustee upon the bankruptcy or reorganization of the Company or otherwise.

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


                                                                              70

          (i)  Each Note Guarantor agrees that it shall not be entitled to any
right of subrogation in relation to the Holders in respect of any Guaranteed
Obligations guaranteed hereby until payment in full of all Guaranteed
Obligations and all obligations to which the Guaranteed Obligations are
subordinated as provided in Article 12.  Each Note Guarantor further agrees
that, as between it, on the one hand, and the Holders and the Trustee, on the
other hand, (i) the maturity of the Guaranteed Obligations guaranteed hereby may
be accelerated as provided in Article 6 for the purposes of any Note Guarantee
herein, notwithstanding any stay, injunction or other prohibition preventing
such acceleration in respect of the Guaranteed Obligations guaranteed hereby,
and (ii) in the event of any declaration of acceleration of such Guaranteed
Obligations as provided in Article 6, such Guaranteed Obligations (whether or
not due and payable) shall forthwith become due and payable by such Note
Guarantor for the purposes of this Section 11.01.

          (j)  Upon request of the Trustee, each Note Guarantor shall execute
and deliver such further instruments and do such further acts as may be
reasonably necessary or proper to carry out more effectively the purpose of this
Indenture.

          SECTION 11.02.  Limitation on Liability.  (a)  Any term or provision
                          ------------------------
of this Indenture to the contrary notwithstanding, the maximum aggregate amount
of the Guaranteed Obligations guaranteed hereunder by any Note Guarantor shall
not exceed the maximum amount that can be hereby guaranteed without rendering
this Indenture, as it relates to such Note Guarantor, voidable under applicable
law relating to fraudulent conveyance or fraudulent transfer or similar laws
affecting the rights of creditors generally.

          (b)  A Note Guarantee as to any Note Guarantor shall terminate and be
of no further force or effect and such Note Guarantor shall be deemed to be
released from all obligations under this Article 11 upon (i) the merger or
consolidation of such Note Guarantor with or into any Person other than the
Company or a Subsidiary of the Company where such Note Guarantor is not the
surviving entity of such consolidation or merger or (ii) the sale by the Company
or any Subsidiary of the Company (or any pledgee of the Company) of the Capital
Stock of such Note Guarantor, where, after such sale, such Note Guarantor is no
longer a Subsidiary of the Company; provided, however, that each such merger,
                                    --------  -------
consolidation or sale (or, in the case of a sale by such a pledgee, the
disposition of the proceeds of such sale) shall comply with Section 4.06 and
Section 5.01(b).  At the request of the Company, the Trustee shall execute and
deliver an appropriate instrument evidencing such release (in the form provided
by the Company).

          SECTION 11.03.  Successors and Assigns.  This Article 11 shall be
                          -----------------------
binding upon each Note Guarantor and (subject to the provisions hereof) its
successors and assigns and shall inure to the benefit of the successors and
assigns of the Trustee and the Holders and, in the event of any transfer or
assignment of rights by any Holder or the Trustee, the rights and privileges
conferred upon that party in this Indenture and in the Securities shall
automatically extend to and be vested in such transferee or assignee, all
subject to the terms and conditions of this Indenture.


                                                                              71

          SECTION 11.04.  No Waiver.  Neither a failure nor a delay on the part
                          ----------
of either the Trustee or the Holders in exercising any right, power or privilege
under this Article 11 shall operate as a waiver thereof, nor shall a single or
partial exercise thereof preclude any other or further exercise of any right,
power or privilege.  The rights, remedies and benefits of the Trustee and the
Holders herein expressly specified are cumulative and not exclusive of any other
rights, remedies or benefits which either may have under this Article 11 at law,
in equity, by statute or otherwise.

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

          SECTION 11.06.  Execution of Supplemental Indenture for Future Note
                          ---------------------------------------------------
Guarantors.  Each Subsidiary which is required to become a Note Guarantor
- -----------
pursuant to Section 4.11 shall promptly execute and deliver to the Trustee a
supplemental indenture in the form of Exhibit C hereto pursuant to which such
Subsidiary shall become a Note Guarantor under this Article 11 and shall
guarantee the Guaranteed Obligations.  Concurrently with the execution and
delivery of such supplemental indenture, the Company shall deliver to the
Trustee an Opinion of Counsel and an Officers' Certificate to the effect that
such supplemental indenture has been duly authorized, executed and delivered by
such Subsidiary and that, subject to the application of bankruptcy, insolvency,
moratorium, fraudulent conveyance or transfer and other similar laws relating to
creditors' rights generally and to the principles of equity, whether considered
in a proceeding at law or in equity, the Note Guarantee of such Note Guarantor
is a legal, valid and binding obligation of such Note Guarantor, enforceable
against such Note Guarantor in accordance with its terms and or to such other
matters as the Trustee may reasonably request.

          SECTION 11.07. Non-Impairment. The failure to endorse a Note Guarantee
                         ---------------
on any Security shall not affect or impair the validity thereof.


                                  ARTICLE 12

                     Subordination of the Note Guarantees
                     ------------------------------------

          SECTION 12.01.  Agreement To Subordinate.  Each Note Guarantor agrees,
                          -------------------------
and each Holder by accepting a Security agrees, that the obligations of a Note
Guarantor hereunder are subordinated in right of payment, to the extent and in
the manner provided in this Article 12, to the prior payment in full of all
Senior Indebtedness of such Note Guarantor and that the subordination is for the
benefit of and enforceable by the holders of such Senior Indebtedness of such
Note Guarantor.  The obligations hereunder with respect to a Note Guarantor
shall in all


                                                                              72

respects rank pari passu with all other Senior Subordinated Indebtedness of such
              ---- -----
Note Guarantor and shall rank senior to all existing and future Subordinated
Obligations of such Note Guarantor; and only Indebtedness of such Note Guarantor
that is Senior Indebtedness of such Note Guarantor shall rank senior to the
obligations of such Note Guarantor in accordance with the provisions set forth
herein.

          SECTION 12.02.  Liquidation, Dissolution, Bankruptcy.  Upon any
                          -------------------------------------
payment or distribution of the assets of a Note Guarantor to creditors upon a
liquidation or a dissolution of such Note Guarantor or in a bankruptcy,
reorganization, insolvency, receivership or similar proceeding relating to such
Note Guarantor and its properties:

          (a) holders of Senior Indebtedness of such Note Guarantor shall be
     entitled to receive payment in full  of such Senior Indebtedness before
     Holders shall be entitled to receive any payment pursuant to any Guaranteed
     Obligations from such Note Guarantor; and

          (b) until the Senior Indebtedness of such Note Guarantor is paid in
     full, any payment or distribution to which Holders would be entitled but
     for this Article 12 shall be made to holders of such Senior Indebtedness as
     their respective interests may appear, except that Holders may receive
     shares of stock and any debt securities that are subordinated to such
     Senior Indebtedness to at least the same extent as the Note Guarantees.

          SECTION 12.03.  Default on Designated Senior Indebtedness of a Note
                          ---------------------------------------------------
Guarantor.  A Note Guarantor may not make any payment pursuant to any of the
- ----------
Guaranteed Obligations or repurchase, redeem or otherwise retire any Securities
(collectively, "pay its Guarantee") if (a) any Designated Senior Indebtedness of
such Note Guarantor is not paid when due or (b) any other default on any
Designated Senior Indebtedness of such Note Guarantor occurs and the maturity of
such Designated Senior Indebtedness is accelerated in accordance with its terms
unless, in either case, (i) the default has been cured or waived and any such
acceleration has been rescinded or (ii) such Designated Senior Indebtedness has
been paid in full; provided, however, that such Note Guarantor may pay its
                   --------  -------
Guarantee without regard to the foregoing if such Note Guarantor and a
Responsible Officer of the Trustee receive written notice approving such payment
from the Representative of the holders of such Designated Senior Indebtedness
with respect to which either of the events in clause (a) or (b) of this sentence
has occurred and is continuing.  During the continuance of any default (other
than a default described in clause (a) or (b) of the preceding sentence) with
respect to any Designated Senior Indebtedness of a Note Guarantor pursuant to
which the maturity thereof may be accelerated immediately without further notice
(except such notice as may be required to effect such acceleration) or the
expiration of any applicable grace periods, such Note Guarantor may not pay its
Guarantee for a period (a "Guarantee Payment Blockage Period") commencing upon
the receipt by a Responsible Officer of the Trustee (with a copy to such Note
Guarantor and the Company) of written notice (a "Guarantee Blockage Notice") of
such default from the Representative of such Designated Senior Indebtedness of
such Note Guarantor specifying an election to effect a Guarantee Payment
Blockage Period and ending 179 days thereafter (or


                                                                              73

earlier if such Guarantee Payment Blockage Period is terminated (a) by written
notice to a Responsible Officer of the Trustee (with a copy to such Note
Guarantor and the Company) from the Person or Persons who gave such Guarantee
Blockage Notice, (b) because such Designated Senior Indebtedness has been repaid
in full or (c) because the default giving rise to such Guarantee Blockage Notice
is no longer continuing). Notwithstanding the provisions described in the
immediately preceding sentence (but subject to the provisions contained in the
second preceding and in the immediately succeeding sentence), unless the holders
of such Designated Senior Indebtedness or the Representative of such holders
shall have accelerated the maturity of such Designated Senior Indebtedness, such
Note Guarantor may resume to paying its Note Guarantee after such Guarantee
Payment Blockage Period, including any missed payments. Not more than one
Guarantee Blockage Notice may be given with respect to a Note Guarantor in any
consecutive 360-day period, irrespective of the number of defaults with respect
to Designated Senior Indebtedness of such Note Guarantor during such period;
provided, however, that if any Guarantee Blockage Notice within such 360-day
- --------  -------
period is given by or on behalf of any holders of Designated Senior Indebtedness
of such Note Guarantor other than the Bank Indebtedness, the Representative of
the Bank Indebtedness may give another Guarantee Blockage Notice within such
period; provided further,however, that in no event may the total number of days
        ---------------- -------
during which any Guarantee Payment Blockage Period or Periods is in effect
exceed 179 days in the aggregate during any 360 consecutive day period. For
purposes of this Section 12.03, no default or event of default that existed or
was continuing on the date of the commencement of any Guarantee Payment Blockage
Period with respect to the Designated Senior Indebtedness initiating such
Guarantee Payment Blockage Period shall be, or be made, the basis of the
commencement of a subsequent Guarantee Payment Blockage Period by the
Representative of such Designated Senior Indebtedness, whether or not within a
period of 360 consecutive days, unless such default or event of default shall
have been cured or waived for a period of not less than 90 consecutive days.

          SECTION 12.04.  Demand for Payment.  If payment of the Securities is
                          -------------------
accelerated because of an Event of Default and a demand for payment is made on a
Note Guarantor pursuant to Article 11, the Trustee (provided that the Trustee
                                                    --------
shall have received written notice from the Company or such Note Guarantor, on
which notice the Trustee shall be entitled to conclusively rely) shall promptly
notify the holders of the Designated Senior Indebtedness of such Note Guarantor
(or the Representative of such holders) of such demand.  If any Designated
Senior Indebtedness of such Note Guarantor is outstanding, such Note Guarantor
may not pay its Guarantee until five Business Days after such holders or the
Representative of the holders of the Designated Senior Indebtedness of such Note
Guarantor receive notice of such demand and, thereafter, may pay its Guarantee
only if this Article 12 otherwise permits payment at that time.

          SECTION 12.05.  When Distribution Must Be Paid Over.  If a payment or
                          ------------------------------------
distribution is made to Holders that because of this Article 12 should not have
been made to them, the Holders who receive the payment or distribution shall
hold such payment or distribution in trust for holders of the Senior
Indebtedness of the relevant Note Guarantor and pay it over to them as their
respective interests may appear.


                                                                              74

          SECTION 12.06.  Subrogation.  After all Senior Indebtedness of a Note
                          ------------
Guarantor is paid in full  and until the Securities are paid in full in cash,
Holders shall be subrogated to the rights of holders of Senior Indebtedness of
such Note Guarantor to receive distributions applicable to Designated Senior
Indebtedness of such Note Guarantor.  A distribution made under this Article 12
to holders of Senior Indebtedness of such Note Guarantor which otherwise would
have been made to Holders is not, as between such Note Guarantor and Holders, a
payment by such Note Guarantor on Senior Indebtedness of such Note Guarantor.

          SECTION 12.07.  Relative Rights.  This Article 12 defines the relative
                          ----------------
rights of Holders and holders of Senior Indebtedness of a Note Guarantor.
Nothing in this Indenture shall:

          (a) impair, as between a Note Guarantor and Holders, the obligation of
     a Note Guarantor which is absolute and unconditional, to make payments with
     respect to the Guaranteed Obligations to the extent set forth in Article
     11; or

          (b) prevent the Trustee or any Holder from exercising its available
     remedies upon a default by a Note Guarantor under its obligations with
     respect to the Guaranteed Obligations, subject to the rights of holders of
     Senior Indebtedness of such Note Guarantor to receive distributions
     otherwise payable to Holders.

          SECTION 12.08.  Subordination May Not Be Impaired by a Note
                          --------------------------------------------
Guarantor.  No right of any holder of Senior Indebtedness of a Note Guarantor to
- ----------
enforce the subordination of the obligations of such Note Guarantor hereunder
shall be impaired by any act or failure to act by such Note Guarantor or by its
failure to comply with this Indenture.

          SECTION 12.09.  Rights of Trustee and Paying Agent.  Notwithstanding
                          -----------------------------------
Section 12.03, the Trustee or the Paying Agent may continue to make payments on
the Securities and shall not be charged with knowledge of the existence of facts
that would prohibit the making of any such payments unless, not less than two
Business Days prior to the date of such payment, a Responsible Officer of the
Trustee receives notice satisfactory to it that payments may not be made under
this Article 12.  A Note Guarantor, the Registrar or co-registrar, the Paying
Agent, a Representative or a holder of Senior Indebtedness of a Note Guarantor
may give the notice; provided, however, that if an issue of Senior Indebtedness
                     --------  -------
of a Note Guarantor has a Representative, only the Representative may give the
notice.

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


                                                                              75

          SECTION 12.10.  Distribution or Notice to Representative.  Whenever a
                          -----------------------------------------
distribution is to be made or a notice given to holders of Senior Indebtedness
of a Note Guarantor, the distribution may be made and the notice given to their
Representative (if any).

          SECTION 12.11.  Article 12 Not To Prevent Events of Default or Limit
                          ----------------------------------------------------
Right To Accelerate.  The failure of a Note Guarantor to make a payment on any
- --------------------
of its obligations by reason of any provision in this Article 12 shall not be
construed as preventing the occurrence of a default by such Note Guarantor under
such obligations.  Nothing in this Article 12 shall have any effect on the right
of the Holders or the Trustee to make a demand for payment on a Note Guarantor
pursuant to Article 11.

          SECTION 12.12.  Trustee Entitled To Rely.  Upon any payment or
                          -------------------------
distribution pursuant to this Article 12, the Trustee and the Holders shall be
entitled to rely (a) upon any order or decree of a court of competent
jurisdiction in which any proceedings of the nature referred to in Section 12.02
are pending, (b) upon a certificate of the liquidating trustee or agent or other
Person making such payment or distribution to the Trustee or to the Holders or
(c) upon the Representatives for the holders of Senior Indebtedness of a Note
Guarantor for the purpose of ascertaining the Persons entitled to participate in
such payment or distribution, the holders of the Senior Indebtedness of a Note
Guarantor and other Indebtedness of a Note Guarantor, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts pertinent thereto or to this Article 12.  In the event that the Trustee
determines, in good faith, that evidence is required with respect to the right
of any Person as a holder of Senior Indebtedness of a Note Guarantor to
participate in any payment or distribution pursuant to this Article 12, the
Trustee may request such Person to furnish evidence to the reasonable
satisfaction of the Trustee as to the amount of Senior Indebtedness of such Note
Guarantor held by such Person, the extent to which such Person is entitled to
participate in such payment or distribution and other facts pertinent to the
rights of such Person under this Article 12, and, if such evidence is not
furnished, the Trustee may defer any payment to such Person pending judicial
determination as to the right of such Person to receive such payment.  The
provisions of Sections 7.01 and 7.02 shall be applicable to all actions or
omissions of actions by the Trustee pursuant to this Article 12.

          SECTION 12.13.  Trustee To Effectuate Subordination.  Each Holder by
                          ------------------------------------
accepting a Security authorizes and directs the Trustee on his or her behalf to
take such action as may be necessary or appropriate to acknowledge or effectuate
the subordination between the Holders and the holders of Senior Indebtedness of
each of the Note Guarantors as provided in this Article 12 and appoints the
Trustee as attorney-in-fact for any and all such purposes.

          SECTION 12.14.  Trustee Not Fiduciary for Holders of Senior
                          -------------------------------------------
Indebtedness of a Note Guarantor.  The Trustee shall not be deemed to owe any
- ---------------------------------
fiduciary duty to the holders of Senior Indebtedness of a Note Guarantor and
shall not be liable to any such holders if it shall mistakenly pay over or
distribute to Holders or the relevant Note Guarantor or any other Person, money
or assets to which any holders of Senior Indebtedness of such Note Guarantor
shall be entitled by virtue of this Article 12 or otherwise.


                                                                              76



          SECTION 12.15.  Reliance by Holders of Senior Indebtedness of a Note
                          ----------------------------------------------------
Guarantor on Subordination Provisions.  Each Holder by accepting a Security
- --------------------------------------
acknowledges and agrees that the foregoing subordination provisions are, and are
intended to be, an inducement and a consideration to each holder of any Senior
Indebtedness of a Note Guarantor, whether such Senior Indebtedness was created
or acquired before or after the issuance of the Securities, to acquire and
continue to hold, or to continue to hold, such Senior Indebtedness and such
holder of Senior Indebtedness shall be deemed conclusively to have relied on
such subordination provisions in acquiring and continuing to hold, or in
continuing to hold, such Senior Indebtedness.

          SECTION 12.16.  Defeasance.  The terms of this Article 12 shall not
                          -----------
apply to payments from money or the proceeds of U.S. Government Obligations held
in trust by the Trustee for the payment of principal of and interest on the
Securities pursuant to the provisions described in Section 8.03.

                                  ARTICLE 13

                                 Miscellaneous
                                 -------------

          SECTION 13.01.  Trust Indenture Act Controls. If and to the extent
                          -----------------------------
that any provision of this Indenture limits, qualifies or conflicts with the
duties imposed by, or with another provision (an "incorporated provision")
included in this Indenture by operation of, TIA" 310 to 318, inclusive, such
imposed duties or incorporated provision shall control.

          SECTION 13.02.  Notices.  Any notice or communication shall be in

direction, waiver or consent, Securities owned by the Company, any Note
Guarantor or by any Person directly or indirectly controlling or controlled by

Beneficial Interest in a Global Security.  A Definitive Security may not be

of a Definitive Security, duly endorsed or accompanied by a written instrument
of transfer in form reasonably satisfactory to the Company and the Registrar,
together with:


                                                                               6

     (i)  certification (in the form set forth on the reverse side of the
     Initial Security) that such Definitive Security is being transferred (1) to
     a QIB in accordance with Rule 144A, (2) to an IAI that has furnished to the
     Trustee a signed letter substantially in the form of Exhibit D or (3)
     outside the United States in an offshore transaction within the meaning of
     Regulation S and in compliance with Rule 904 under the Securities Act; and

     (ii) written instructions directing the Trustee to make, or to direct
     the Securities Custodian to make, an adjustment on its books and records
     with respect to such Global Security to reflect an increase in the
     aggregate principal amount of the Securities represented by the Global

     principal amount of Securities represented by the Global Security to be
     increased by the aggregate principal amount of the Definitive Security to
     be exchanged and shall credit or cause to be credited to the account of the
     Person specified in such instructions a beneficial interest in the Global
     Security equal to the principal amount of the Definitive Security so

     Security has not been previously exchanged for certificated securities
     pursuant to Section 2.4, the Company shall issue and the Trustee shall
     authenticate, upon written order of the Company in the form of an Officers'
     Certificate, a new Global Security in the appropriate principal amount.

          (c)  Transfer and Exchange of Global Securities.  (i)  The transfer
               -------------------------------------------
and exchange of Global Securities or beneficial interests therein shall be
effected through the Depositary, in accordance with this Indenture (including
applicable restrictions on transfer set forth herein, if any) and the procedures
of the Depositary therefor.  A transferor of a beneficial interest in a Global
Security shall deliver a written order given in accordance with the Depositary's
procedures containing information regarding the participant account of the
Depositary to be credited with a beneficial interest in such Global Security or
another Global Security and such account shall be credited in accordance with
such order with a beneficial interest in the applicable Global Security and the
account of the Person making the transfer shall be debited by an amount equal to
the beneficial interest in the Global Security being transferred.  Transfers by
an owner of a beneficial interest in the Rule 144A Global Security or the IAI
Global Security to a transferee who takes delivery of such interest through the
Regulation S Global Security, whether before or after the expiration of the
Restricted Period, shall be made only upon receipt by the Trustee of a
certification in the form provided on the reverse of the Initial Securities from
the transferor to the effect that such transfer is being made in accordance with
Regulation S or (if available) Rule 144 under the Securities Act and that, if
such transfer is being made prior to the expiration of the Restricted Period,
the interest transferred shall be held immediately thereafter through Euroclear
or Cedel.  In the case of a transfer of a beneficial interest in either the
Regulation S Global Security or the Rule 144A Global Security for an interest in
the IAI Global Security, the transferee must furnish a signed letter
substantially in the form of Exhibit D to the Trustee.


                                                                               7

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

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

     (iv)  In the event that a Global Security is exchanged for Definitive
     Securities pursuant to Section 2.4 prior to the consummation of the
     Registered Exchange Offer or the effectiveness of the Shelf Registration
     Statement with respect to such Securities, such Securities may be exchanged
     only in accordance with such procedures as are substantially consistent
     with the provisions of this Section 2.3 (including the certification
     requirements set forth on the reverse of the Initial Securities intended to
     ensure that such transfers comply with Rule 144A, Regulation S or such
     other applicable exemption from registration under the Securities Act, as
     the case may be) and such other procedures as may from time to time be
     adopted by the Company.

          (d) Restrictions on Transfer of Regulation S Global Security.   (i)
              ---------------------------------------------------------
Prior to the expiration of the Restricted Period, interests in the Regulation S
Global Security may only be held through Euroclear or Cedel.  During the
Restricted Period, beneficial ownership interests in the Regulation S Global
Security may only be sold, pledged or transferred through Euroclear or Cedel in
accordance with the Applicable Procedures and only (1) to the Company, (2) so
long as such security is eligible for resale pursuant to Rule 144A, to a person

account or for the account of a QIB to whom notice is given that the resale,
pledge or transfer is being made in reliance on Rule 144A, (3) in an offshore
transaction in accordance with Regulation S, (4) pursuant to an exemption from
registration under the Securities Act provided by Rule 144 (if applicable) under
the Securities Act, (5) to an IAI purchasing for its own account, or for the
account of such an IAI, in a minimum principal amount of Securities of $250,000
or (6) pursuant to an effective registration statement under the Securities Act,
in each case in accordance with any applicable securities laws of any state of
the United States.  Prior to the expiration of the Restricted Period, transfers
by an owner of a beneficial interest in the Regulation S Global Security to a
transferee who takes delivery of such interest through the Rule 144A Global
Security or the IAI Global Security shall be made only in accordance with
Applicable Procedures and upon receipt by the Trustee of a written certification
from the transferor of the beneficial interest in the form provided on the
reverse of the Initial Security to the effect that such transfer is being made
to (1) a QIB within the meaning of Rule 144A in a transaction meeting the
requirements of Rule 144A or (2) an IAI


                                                                               8

purchasing for its own account, or for the account of such an IAI, in a minimum
principal amount of the Securities of $250,000. Such written certification shall
no longer be required after the expiration of the Restricted Period. In the case
of a transfer of a beneficial interest in the Regulation S Global Security for
an interest in the IAI Global Security, the transferee must furnish a signed
letter substantially in the form of Exhibit D to the Trustee.

          (ii) Upon the expiration of the Restricted Period, beneficial
     ownership interests in the Regulation S Global Security shall be
     transferable in accordance with applicable law and the other terms of this

     LEGEND WILL BE REMOVED UPON THE REQUEST OF THE HOLDER AFTER THE RESALE
     RESTRICTION TERMINATION DATE."

Each Definitive Security shall bear the following additional legend:

     "IN CONNECTION WITH ANY TRANSFER, THE HOLDER WILL DELIVER TO THE REGISTRAR
     AND TRANSFER AGENT SUCH CERTIFICATES AND OTHER INFORMATION AS SUCH TRANSFER
     AGENT MAY REASONABLY REQUIRE TO CONFIRM THAT THE TRANSFER COMPLIES WITH THE
     FOREGOING RESTRICTIONS."

          (ii)  Upon any sale or transfer of a Transfer Restricted Security that
     is a Definitive Security, the Registrar shall permit the Holder thereof to
     exchange such Transfer Restricted Security for a Definitive Security that
     does not bear the legends set forth above and rescind any restriction on
     the transfer of such Transfer Restricted Security if the Holder certifies
     in writing to the Registrar that its request for such exchange was made in
     reliance on Rule 144 (such certification to be in the form set forth on the
     reverse of the Initial Security).

          (iii) After a transfer of any Initial Securities or Private Exchange
     Securities during the period of the effectiveness of a Shelf Registration
     Statement with respect to such Initial Securities or Private Exchange
     Securities, as the case may be, all requirements pertaining to the
     Restricted Securities Legend on such Initial Securities or such Private
     Exchange Securities shall cease to apply and the requirements that any such
     Initial Securities or such Private Exchange Securities be issued in global

     respect to the Initial Securities pursuant to which Holders of such Initial
     Securities are offered Exchange Securities in exchange for their Initial
     Securities, all requirements pertaining to Initial Securities that Initial

     Registered Exchange Offer.

          (v)   Upon the consummation of a Private Exchange with respect to the
     Initial Securities pursuant to which Holders of such Initial Securities are
     offered Private Exchange Securities in exchange for their Initial
     Securities, all requirements pertaining to such Initial Securities that
     Initial Securities be issued in global form shall continue to apply, and
     Private Exchange Securities in global form with the Restricted Securities

     Period of any Initial Security acquired pursuant to Regulation S, all
     requirements that such Initial Security bear the Restricted Securities
     Legend shall cease to apply and the requirements requiring any such Initial

                ---------------------------------------------
all beneficial interests in a Global Security have either been exchanged for
Definitive Securities, transferred, redeemed, repurchased or canceled, such
Global Security shall be returned by the Depositary to the Trustee for
cancelation or retained and canceled by the Trustee.  At any time prior to such
cancelation, if any beneficial interest in a Global Security is exchanged for
Definitive Securities, transferred in exchange for an interest in another Global
Security, redeemed, repurchased or canceled, the principal amount of Securities
represented by such Global Security shall be reduced and an adjustment shall be
made on the books and records of the Trustee (if it is then the Securities
Custodian for such Global Security) with respect to such Global Security, by the
Trustee or the Securities Custodian, to reflect such reduction.

          (g)   Obligations with Respect to Transfers and Exchanges of
                ------------------------------------------------------
Securities.

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

          (ii)  No service charge shall be made for any registration of transfer
     or exchange, but the Company may require payment of a sum sufficient to
     cover any transfer tax, assessments, or similar governmental charge payable
     in connection therewith (other than any such transfer taxes, assessments or
     similar governmental charge payable upon exchanges pursuant to Sections
     2.06, 3.06, 4.06, 4.08 and 9.05 of this Indenture).

          (iii) Prior to the due presentation for registration of transfer of
     any Security, the Company, the Trustee, the Paying Agent or the Registrar
     may deem and treat the person in whose name a Security is registered as the
     absolute owner of such Security for the purpose of receiving payment of
     principal of and interest on such Security and for all other purposes
     whatsoever, whether or not such Security is overdue, and none of the

     Company, the Trustee, the Paying Agent or the Registrar shall be affected
     by notice to the contrary.

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

          (h)  No Obligation of the Trustee.
               -----------------------------

          (i)  The Trustee shall have no responsibility or obligation to any
     beneficial owner of a Global Security, a member of, or a participant in the
     Depositary or any other Person with respect to the accuracy of the records
     of the Depositary or its nominee or of any participant or member thereof,
     with respect to any ownership interest in the Securities or with respect to
     the delivery to any participant, member, beneficial owner or other Person
     (other than the Depositary) of any notice (including any notice of
     redemption or repurchase) or the payment of any amount, under or with
     respect to such Securities.  All notices and communications to be given to
     the Holders and all payments to be made to Holders under the Securities
     shall be given or made only to the registered Holders (which shall be the
     Depositary or its nominee in the case of a Global Security).  The rights of
     beneficial owners in any Global Security shall be exercised only through
     the Depositary subject to the applicable rules and procedures of the
     Depositary.  The Trustee may rely and shall be fully protected in relying
     upon information furnished by the Depositary with respect to its members,
     participants and any beneficial owners.

          (ii) The Trustee shall have no obligation or duty to monitor,
     determine or inquire as to compliance with any restrictions on transfer
     imposed under this Indenture or under applicable law with respect to any
     transfer of any interest in any Security (including any transfers between
     or among Depositary participants, members or beneficial owners in any
     Global Security) other than to require delivery of such certificates and
     other documentation or evidence as are expressly required by, and to do so
     if and when expressly required by, the terms of this Indenture, and to
     examine the same to determine substantial compliance as to form with the
     express requirements hereof.

     2.4  Definitive Securities
          ---------------------

          (a)  A Global Security deposited with the Depositary or with the
Trustee as Securities Custodian pursuant to Section 2.1 or issued in connection
with a Registered Exchange Offer or Private Exchange shall be transferred to the
beneficial owners thereof in the form of Definitive Securities in an aggregate
principal amount equal to the principal amount of such Global Security, in
exchange for such Global Security, only if such transfer complies with Section
2.3 and (i) the Depositary notifies the Company that it is unwilling or unable
to continue as a Depositary for such Global Security or if at any time the
Depositary ceases to be a "clearing agency" registered under the Exchange Act,

such notice or after the Company becomes aware of such cessation, or (ii) an
Event of Default has occurred and is continuing or (iii) the Company, in its

discretion, notifies the Trustee in writing that it elects to cause the issuance
of certificated Securities under this Indenture.

          (b)  Any Global Security that is transferable to the beneficial owners
thereof pursuant to this Section 2.4 shall be surrendered by the Depositary to
the Trustee, to be so transferred, in whole or from time to time in part,
without charge, and the Trustee shall authenticate and deliver, upon such
transfer of each portion of such Global Security, an equal aggregate principal
amount of Definitive Securities of authorized denominations.  Any portion of a
Global Security transferred pursuant to this Section shall be executed,
authenticated and delivered only in denominations of $1,000 and any integral
multiple thereof and registered in such names as the Depositary shall direct.
Any certificated Initial Security in the form of a Definitive Security delivered
in exchange for an interest in the Global Security shall, except as otherwise
provided by Section 2.3(e), bear the Restricted Securities Legend.

          (c)  Subject to the provisions of Section 2.4(b), the registered
Holder of a Global Security may grant proxies and otherwise authorize any
Person, including Agent Members and Persons that may hold interests through
Agent Members, to take any action which a Holder is entitled to take under this
Indenture or the Securities.

          (d)  In the event of the occurrence of any of the events specified in
Section 2.4(a)(i), (ii) or (iii), the Company will promptly make available to
the Trustee a reasonable supply of Definitive Securities in fully registered
form without interest coupons.


                                                                       EXHIBIT A

1.   Interest
     --------

          (a)  BETTER MINERALS & AGGREGATES COMPANY, a Delaware corporation
(such corporation, and its successors and assigns under the Indenture
hereinafter referred to, being herein called the "Company"), promises to pay
interest on the principal amount of this Security at the rate per annum shown
above. The Company shall pay interest semiannually on March 15 and September 15
of each year. Interest on the Securities shall accrue from the most recent date
to which interest has been paid or duly provided for or, if no interest has been
paid or duly provided for, from October 1, 1999 until the principal hereof is
due. Interest shall be computed on the basis of a 360-day year of twelve 30-day
months. The Company shall pay interest on overdue principal at the rate borne by
the Securities plus 1% per annum, and it shall pay interest on overdue
installments of interest at the same rate to the extent lawful.

          (b)  Liquidated Damages.  The holder of this Security is entitled to
               ------------------
the benefits of an Exchange and Registration Rights Agreement, dated as of
October 1, 1999, among the Company, U.S. SILICA COMPANY, BETTER MATERIALS
CORPORATION, GEORGE F. PETTINOS, INC., OTTAWA SILICA COMPANY, THE FULTON LAND
AND TIMBER COMPANY, PENNSYLVANIA GLASS SAND CORPORATION, BUCKS COUNTY CRUSHED
STONE COMPANY, CHIPPEWA FARMS CORPORATION, SHORE STONE COMPANY, INC., BMC
TRUCKING, INC., ELLEN JAY, INC., STONE MATERIALS COMPANY, LLC, COMMERCIAL STONE
CO., INC. and COMMERCIAL AGGREGATES TRANSPORTATION AND SALES, LLC (the "Note
Guarantors") and the Initial Purchasers named therein (the "Registration
Agreement").  Capitalized terms used in this paragraph (b) but not defined
herein have the meanings assigned to them in the Registration Agreement.  If (i)
the Shelf Registration Statement or Exchange Offer Registration Statement, as
applicable under the Registration Agreement, is not filed with the Commission on
or prior to 135 days after the Issue Date, (ii) the Exchange Offer Registration
Statement or the Shelf Registration Statement, as the case may be, is not
declared effective within 195 days after the Issue Date, (iii) the Registered
Exchange Offer is not consummated on or prior to 240 days after the Issue Date,
or (iv) the Shelf Registration Statement is filed and declared effective within
195 days after the Issue Date but shall thereafter cease to be effective (at any
time that the Company is obligated to maintain the effectiveness thereof)
without being succeeded within 45 days by an additional Registration Statement
filed and declared effective (each such event referred to in clauses (i) through
(iv), a "Registration Default"), the Company shall pay liquidated damages to
each holder of Transfer Restricted Securities, during the period of such
Registration Default, in an amount equal to $0.192 per week per $1,000 principal
amount of the Securities constituting Transfer Restricted Securities held by
such holder until the applicable Registration Statement is filed or declared
effective, the Registered Exchange Offer is consummated or the Shelf
Registration Statement again becomes effective, as the case may be.  All accrued
liquidated damages shall be paid to


                                                                               2

holders in the same manner as interest payments on the Securities on semi-annual
payment dates which correspond to interest payment dates for the Securities.
Following the cure of all Registration Defaults, the accrual of liquidated
damages shall cease. The Trustee shall have no responsibility with respect to
the determination of the amount of any such liquidated damages. For purposes of
the foregoing, "Transfer Restricted Securities" means (i) each Initial Security
until the date on which such Initial Security has been exchanged for a freely
transferable Exchange Security in the Registered Exchange Offer, (ii) each
Initial Security or Private Exchange Security until the date on which such
Initial Security or Private Exchange Security has been effectively registered
under the Securities Act and disposed of in accordance with a Shelf Registration
Statement or (iii) each Initial Security or Private Exchange Security until the
date on which such Initial Security or Private Exchange Security is distributed
to the public pursuant to Rule 144 under the Securities Act or is saleable
pursuant to Rule 144(k) under the Securities Act.

2.   Method of Payment
     -----------------

          The Company shall pay interest on the Securities (except defaulted
interest) to the Persons who are registered holders of Securities at the close
of business on the March 1 or September 1 next preceding the interest payment
date even if Securities are canceled after the record date and on or before the
interest payment date.  Holders must surrender Securities to a Paying Agent to
collect principal payments.  The Company shall pay principal, premium,
liquidated damages, if any, and interest in money of the United States of
America that at the time of payment is legal tender for payment of public and
private debts.  Payments in respect of the Securities represented by a Global
Security (including principal, premium, liquidated damages, if any, and
interest) shall be made by wire transfer of immediately available funds to the
accounts specified by The Depository Trust Company.  The Company will make all
payments in respect of a certificated Security (including principal, premium and
interest), and the Securities may be exchanged or transferred, at the office or
agency of the Company in the Borough of Manhattan, The City of New York (which
initially shall be the Corporate Trust Office of the Trustee, at 101 Barclay
Street, New York, New York 10286), except that, at the option of the Company,
payment of interest may be made by check mailed directly to Holders at their
registered addresses; provided, however, that payments on the Securities may
                      --------  -------
also be made, in the case of a Holder of at least $1,000,000 aggregate principal
amount of Securities, by wire transfer to a U.S. dollar account maintained by
the payee with a bank in the United States if such Holder elects payment by wire
transfer by giving written notice to the Trustee or the Paying Agent to such
effect designating such account no later than 30 days immediately preceding the
relevant due date for payment (or such other date as the Trustee may accept in
its discretion).

3.   Paying Agent and Registrar
     --------------------------

          Initially, THE BANK OF NEW YORK, a New York banking corporation (the
"Trustee"), will act as Paying Agent and Registrar.  The Company may appoint and
change any Paying Agent, Registrar or co-registrar without notice.  The Company
or any of its domestically incorporated Wholly Owned Subsidiaries may act as
Paying Agent, Registrar or co-registrar.


                                                                               3

4.   Indenture
     ---------

          The Company issued the Securities under an Indenture dated as of
October 1, 1999 (the "Indenture"), among the Company, the Note Guarantors and
the Trustee.  The terms of the Securities include those stated in the Indenture
and those made part of the Indenture by reference to the Trust Indenture Act of
1939 (15 U.S.C. " 77aaa-77bbbb) as in effect on the date of the Indenture (the
         ------
"TIA").  Terms defined in the Indenture and not defined herein have the meanings
ascribed thereto in the Indenture.  The Securities are subject to all terms and
provisions of the Indenture, and Holders (as defined in the Indenture) are
referred to the Indenture and the TIA for a statement of such terms and
provisions.

          The Securities are senior subordinated unsecured obligations of the
Company limited to $150,000,000 aggregate principal amount at any one time
outstanding (subject to Section 2.07 of the Indenture).  This Security is one of
the [Initial] [Private Exchange] Securities referred to in the Indenture issued
in an aggregate principal amount of $150,000,000.  The Securities include the
Initial Securities and any Exchange Securities and Private Exchange Securities
issued in exchange for Initial Securities.  The Initial Securities, the Exchange
Securities and the Private Exchange Securities are treated as a single class of
securities under the Indenture.  The Indenture imposes certain limitations on
the ability of the Company and its Restricted Subsidiaries to, among other
things, make certain Investments and other Restricted Payments, pay dividends
and other distributions, incur Indebtedness, enter into consensual restrictions
upon the payment of certain dividends and distributions by such Restricted
Subsidiaries, issue or sell shares of capital stock of such Restricted
Subsidiaries, enter into or permit certain transactions with Affiliates, and
make asset sales.  The Indenture also imposes limitations on the ability of the
Company to consolidate or merge with or into any other Person or convey,
transfer or lease all or substantially all of the property of the Company.

          To guarantee the due and punctual payment of the principal and
interest on the Securities and all other amounts payable by the Company under
the Indenture and the Securities when and as the same shall be due and payable,
whether at maturity, by acceleration or otherwise, according to the terms of the
Securities and the Indenture, the Note Guarantors have jointly and severally
unconditionally guaranteed the Guaranteed Obligations on a senior subordinated
basis pursuant to the terms of the Indenture.

thereof, plus accrued and unpaid interest and liquidated damages thereon, if

          Notice of redemption will be mailed by first-class mail at least 30
days but not more than 60 days before the redemption date to each Holder of
Securities to be redeemed at his or her registered address.  Securities in
denominations larger than $1,000 may be redeemed in part but only in whole

(or portions thereof) to be redeemed on the redemption date is deposited with
the Paying Agent on or before the redemption date and certain other conditions
are satisfied, on and after such date interest ceases to accrue on such
Securities (or such portions thereof) called for redemption.

8.  Repurchase of Securities at the Option of Holders upon Change of Control
    ------------------------------------------------------------------------

          Upon a Change of Control, any Holder of Securities will have the
right, subject to certain conditions specified in the Indenture, to cause the
Company to repurchase all or any part of the Securities of such Holder at a
purchase price equal to 101% of the principal amount of the Securities to be
repurchased plus accrued and unpaid interest and liquidated damages, if any, to


                                                                               5

the date of repurchase (subject to the right of Holders of record on the
relevant record date to receive interest due on the relevant interest payment
date that is on or prior to the date of purchase) as provided in, and subject to
the terms of, the Indenture.

          In accordance with Section 4.06 of the Indenture, the Company will be
required to offer to purchase Securities upon the occurrence of certain events.

9.  Subordination
    -------------

          The Securities are subordinated to Senior Indebtedness, as defined in
the Indenture.  To the extent provided in the Indenture, Senior Indebtedness
must be paid before the Securities may be paid.  The Company and each Note
Guarantor agrees, and each Holder by accepting a Security agrees, to the
subordination provisions contained in the Indenture and authorizes the Trustee
to give it effect and appoints the Trustee as attorney-in-fact for such purpose.

10. Denominations; Transfer; Exchange
    ---------------------------------

          The Securities are in registered form without coupons in denominations
of $1,000 and whole multiples of $1,000.  A Holder may transfer or exchange
Securities in accordance with the Indenture.  Upon any transfer or exchange, the
Registrar and the Trustee may require a Holder, among other things, to furnish
appropriate endorsements or transfer documents and to pay any taxes required by
law or permitted by the Indenture.  The Registrar need not register the transfer
of or exchange any Securities selected for redemption (except, in the case of a
Security to be redeemed in part, the portion of the Security not to be redeemed)
or to transfer or exchange any Securities for a period of 15 days prior to a
selection of Securities to be redeemed.

11. Persons Deemed Owners
    ---------------------

          Except as provided in paragraph 2 hereof, the registered Holder of
this Security may be treated as the owner of it for all purposes.

12. Unclaimed Money
    ---------------

          If money for the payment of principal or interest remains unclaimed
for two years, the Trustee or Paying Agent shall pay the money back to the
Company at its written request unless an abandoned property law designates
another Person.  After any such payment, Holders entitled to the money must look
only to the Company and not to the Trustee for payment.

13. Discharge and Defeasance
    ------------------------

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


                                                                               6

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

14.  Amendment, Waiver
     -----------------

          Subject to certain exceptions set forth in the Indenture, (i) the
Indenture or the Securities may be amended without prior notice to any Holder
but with the written consent of the Holders of at least a majority in aggregate
principal amount of the outstanding Securities and (ii) any default may be
waived with the written consent of the Holders of at least a majority in
principal amount of the outstanding Securities.  Subject to certain exceptions
set forth in the Indenture, without the consent of any Holder of Securities, the
Company and the Trustee may amend the Indenture or the Securities (i) to cure
any ambiguity, omission, defect or inconsistency; (ii) to comply with Article 5
of the Indenture; (iii) to provide for uncertificated Securities in addition to
or in place of certificated Securities; (iv) to add Note Guarantees with respect
to the Securities; (v) to secure the Securities; (vi) to add additional
covenants or to surrender rights and powers conferred on the Company; (vii) to
comply with the requirements of the SEC in order to effect or maintain the
qualification of the Indenture under the TIA; (viii) to make any change that
does not adversely affect the rights of any Holder; (ix) to make any change in
the subordination provisions of the Indenture that would limit or terminate the
benefits available to any holder of Senior Indebtedness of the Company (or any
representative thereof) under such subordination provisions; or (x) to provide
for the issuance of the Exchange Securities or Private Exchange Securities.

15.  Defaults and Remedies
     ---------------------

          If an Event of Default occurs (other than an Event of Default relating
to certain events of bankruptcy, insolvency or reorganization of the Company)
and is continuing, the Trustee or the Holders of at least 25% in principal
amount of the outstanding Securities may declare the principal of and accrued
but unpaid interest on all the Securities to be due and payable.  If an Event of
Default relating to certain events of bankruptcy, insolvency or reorganization
of the Company occurs, the principal of and interest on all the Securities shall
become immediately due and payable without any declaration or other act on the
part of the Trustee or any Holders.  Under certain circumstances, the Holders of
a majority in principal amount of the outstanding Securities may rescind any
such acceleration with respect to the Securities and its consequences.

          If an Event of Default occurs and is continuing, the Trustee shall be
under no obligation to exercise any of the rights or powers under the Indenture
at the request or direction of any of the Holders unless such Holders have
offered to a Responsible Officer of the Trustee reasonable indemnity or security
reasonably satisfactory to the Trustee against any loss, liability or expense
and certain other conditions are complied with.  Except to enforce the right to
receive payment of principal, premium (if any) or interest when due, no Holder
may pursue any remedy with respect to the Indenture or the Securities unless (i)
such Holder has previously given the Trustee notice that an Event of Default is
continuing, (ii) Holders of at least 25% in principal


                                                                               7

amount of the outstanding Securities have requested the Trustee in writing to
pursue the remedy, (iii) such Holders have offered the Trustee reasonable
security or indemnity reasonably satisfactory to the Trustee against any loss,
liability or expense, (iv) the Trustee has not complied with such request within
60 days after the receipt of the request and the offer of security or indemnity
and (v) the Holders of a majority in principal amount of the outstanding
Securities have not given the Trustee a direction inconsistent with such request
within such 60-day period. Subject to certain restrictions, the Holders of a
majority in principal amount of the outstanding Securities are given the right
to direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee or of exercising any trust or power conferred on the
Trustee. The Trustee, however, may refuse to follow any direction that conflicts
with law or the Indenture or that the Trustee determines is unduly prejudicial
to the rights of any other Holder or that would involve the Trustee in personal
liability. Prior to taking any action under the Indenture, the Trustee shall be
entitled to indemnification satisfactory to it in its sole discretion against
all losses and expenses caused by taking or not taking such action.

16.  Trustee Dealings with the Company
     ---------------------------------

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

17.  No Recourse Against Others
     --------------------------

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

18.  Authentication
     --------------

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

19.  Abbreviations
     -------------

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


                                                                               8

20.  Governing Law
     -------------

          THIS SECURITY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH,
THE LAWS OF THE STATE OF NEW YORK 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.

21.  CUSIP and ISIN Numbers
     ----------------------

          The Company has caused CUSIP [and ISIN] numbers to be printed on the
Securities and has directed the Trustee to use CUSIP [and ISIN] 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 Securities or as
contained in any notice of redemption and reliance may be placed only on the
other identification numbers placed thereon.

          The Company will furnish to any Holder of Securities upon written
request and without charge to the Holder a copy of the Indenture which has in it
the text of this Security.


                                                                               9

                  [FORM OF REVERSE SIDE OF EXCHANGE SECURITY]

                     13% Senior Subordinated Note due 2009


1.  Interest.
    --------

          BETTER MINERALS & AGGREGATES COMPANY, a Delaware corporation (such
corporation, and its successors and assigns under the Indenture hereinafter
referred to, being herein called the "Company"), promises to pay interest on the
principal amount of this Security at the rate per annum shown above. The Company
shall pay interest semiannually on March 15 and September 15 of each year.
Interest on the Securities shall accrue from the most recent date to which
interest has been paid or duly provided for or, if no interest has been paid or
duly provided for, from October 1, 1999 until the principal hereof is due.
Interest shall be computed on the basis of a 360-day year of twelve 30-day
months. The Company shall pay interest on overdue principal at the rate borne by
the Securities plus 1% per annum, and it shall pay interest on overdue
installments of interest at the same rate to the extent lawful.

2.  Method of Payment
    -----------------

          The Company shall pay interest on the Securities (except defaulted
interest) to the Persons who are registered holders of Securities at the close
of business on the March 1 or September 1 next preceding the interest payment
date even if Securities are canceled after the record date and on or before the
interest payment date. Holders must surrender Securities to a Paying Agent to
collect principal payments. The Company shall pay principal, premium and
interest in money of the United States of America that at the time of payment is
legal tender for payment of public and private debts. Payments in respect of the
Securities represented by a Global Security (including principal, premium and
interest) shall be made by wire transfer of immediately available funds to the
accounts specified by The Depository Trust Company. The Company will make all
payments in respect of a certificated Security (including principal, premium and
interest), by mailing a check to the registered address of each Holder thereof;
provided, however, that payments on the Securities may also be made, in the case
- --------  -------
of a Holder of at least $1,000,000 aggregate principal amount of Securities, by
wire transfer to a U.S. dollar account maintained by the payee with a bank in
the United States if such Holder elects payment by wire transfer by giving
written notice to the Trustee or the Paying Agent to such effect designating
such account no later than 30 days immediately preceding the relevant due date
for payment (or such other date as the Trustee may accept in its discretion).

3.  Paying Agent and Registrar
    --------------------------

          Initially, THE BANK OF NEW YORK, a New York banking corporation (the
"Trustee"), will act as Paying Agent and Registrar. The Company may appoint and
change any Paying Agent, Registrar or co-registrar without notice. The Company
or any of its domestically incorporated Wholly Owned Subsidiaries may act as
Paying Agent, Registrar or co-registrar.


                                                                               5

4.  Indenture
    ---------

          The Company issued the Securities under an Indenture dated as of
October 1, 1999 (the "Indenture"), among the Company, the Note Guarantors and
the Trustee.  The terms of the Securities include those stated in the Indenture
and those made part of the Indenture by reference to the Trust Indenture Act of
1939 (15 U.S.C." 77aaa-77bbbb) as in effect on the date of the Indenture (the
         ------
"TIA").  Terms defined in the Indenture and not defined herein have the meanings
ascribed thereto in the Indenture.  The Securities are subject to all terms and
provisions of the Indenture, and Holders (as defined in the Indenture) are
referred to the Indenture and the TIA for a statement of such terms and
provisions.

          The Securities are senior subordinated unsecured obligations of the
Company limited to $150,000,000 aggregate principal amount at any one time
outstanding, of which $150,000,000 in aggregate principal amount will be
initially issued on the Closing Date. This Security is one of the Exchange
Securities referred to in the Indenture. The Securities include the Initial
Securities and any Exchange Securities and Private Exchange Securities issued in
exchange for the Initial Securities pursuant to the Indenture. The Initial
Securities, the Exchange Securities and the Private Exchange Securities are
treated as a single class of securities under the Indenture. The Indenture
imposes certain limitations on the ability of the Company and its Restricted
Subsidiaries to, among other things, make certain Investments and other
Restricted Payments, pay dividends and other distributions, incur Indebtedness,
enter into consensual restrictions upon the payment of certain dividends and
distributions by such Restricted Subsidiaries, issue or sell shares of capital
stock of such Restricted Subsidiaries, enter into or permit certain transactions
with Affiliates and make Asset Sales. The Indenture also imposes limitations on
the ability of the Company to consolidate or merge with or into any other Person
or convey, transfer or lease all or substantially all of the property of the
Company.

          To guarantee the due and punctual payment of the principal and
interest, if any, on the Securities and all other amounts payable by the Company
under the Indenture and the Securities when and as the same shall be due and
payable, whether at maturity, by acceleration or otherwise, according to the
terms of the Securities and the Indenture, the Note Guarantors have, jointly and
severally, unconditionally guaranteed the Guaranteed Obligations on a senior
basis subordinated basis pursuant to the terms of the Indenture.

5.  Optional Redemption
    -------------------

          Except as set forth in the following paragraph, the Securities shall
not be redeemable at the option of the Company prior to September 15, 2004.
Thereafter, the Securities shall be redeemable at the option of the Company, in
whole or in part, on not less than 30 nor more than 60 days prior notice, at the
following redemption prices (expressed as percentages of principal amount), plus
accrued and unpaid interest and liquidated damages, if any, to the redemption
date (subject to the right of holders of record on the relevant record date to
receive


                                                                               6

interest due on the relevant interest payment date), if redeemed during the 12-

                                                    Price
   ----------------------------------------------------------

     2004                                         106.500%

          In addition, prior to September 15, 2002, the Company may redeem up to
a maximum of 35% of the original aggregate principal amount of the Securities
with the Net Cash Proceeds of one or more Public Equity Offerings (i) by the
Company or (ii) by Parent or Holdings to the extent the Net Cash Proceeds
thereof are contributed to the Company or used to purchase Capital Stock (other
than Disqualified Stock) of the Company from the Company following which there
is a Public Market, at a redemption price equal to 113% of the principal amount
thereof, plus accrued and unpaid interest and liquidated damages thereon, if
any, to the redemption date (subject to the right of holders of record on the
relevant record date to receive interest due on the relevant interest payment
date); provided, however, that after giving effect to any such redemption, at
       --------  -------
least 65% of the original aggregate principal amount of the Securities remains
outstanding.  Any such redemption shall be made within 90 days of such Public
Equity Offering upon not less than 30 nor more than 60 days notice mailed to
each holder of Securities being redeemed and otherwise in accordance with the
procedures set forth in the Indenture.

6.  Sinking Fund
    ------------

          The Securities are not subject to any sinking fund.

7.  Notice of Redemption
    --------------------

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

8.  Repurchase of Securities at the Option of Holders upon Change of Control
    ------------------------------------------------------------------------

          Upon a Change of Control, any Holder of Securities will have the
right, subject to certain conditions specified in the Indenture, to cause the
Company to repurchase all or any part


                                                                               7

of the Securities of such Holder at a purchase price equal to 101% of the
principal amount of the Securities to be repurchased plus accrued and unpaid
interest and liquidated damages, if any, to the date of repurchase (subject to
the right of Holders of record on the relevant record date to receive interest
due on the relevant interest payment date that is on or prior to the date of
purchase) as provided in, and subject to the terms of, the Indenture.

          In accordance with Section 4.06 of the Indenture, the Company will be
required to offer to purchase Securities upon the occurrence of certain events.

9.   Subordination
     -------------

          The Securities are subordinated to Senior Indebtedness, as defined in
the Indenture. To the extent provided in the Indenture, Senior Indebtedness must
be paid before the Securities may be paid. The Company and each Note Guarantor
agrees, and each Holder by accepting a Security agrees, to the subordination
provisions contained in the Indenture and authorizes the Trustee to give it
effect and appoints the Trustee as attorney-in-fact for such purpose.

10.  Denominations; Transfer; Exchange
     ---------------------------------

          The Securities are in registered form without coupons in denominations
of $1,000 and whole multiples of $1,000. A Holder may transfer or exchange
Securities in accordance with the Indenture. Upon any transfer or exchange, the
Registrar and the Trustee may require a Holder, among other things, to furnish
appropriate endorsements or transfer documents and to pay any taxes required by
law or permitted by the Indenture. The Registrar need not register the transfer
of or exchange any Securities selected for redemption (except, in the case of a
Security to be redeemed in part, the portion of the Security not to be redeemed)
or to transfer or exchange any Securities for a period of 15 days prior to a
selection of Securities to be redeemed or 15 days before an interest payment
date.

11.  Persons Deemed Owners
     ---------------------

          Except as provided in paragraph 2 hereof, the registered Holder of
this Security may be treated as the owner of it for all purposes.

12.  Unclaimed Money
     ---------------

          If money for the payment of principal or interest remains unclaimed
for two years, the Trustee or Paying Agent shall pay the money back to the
Company at its written request unless an abandoned property law designates
another Person.  After any such payment, Holders entitled to the money must look
only to the Company and not to the Trustee for payment.


                                                                               8

13.  Discharge and Defeasance
     ------------------------

          Subject to certain conditions, the Company at any time may terminate
some of or all its obligations under the Securities and the Indenture if the
Company deposits with the Trustee money or U.S. Government Obligations for the
payment of principal and interest on the Securities to redemption or maturity,
as the case may be.

14.  Amendment, Waiver
     -----------------

          Subject to certain exceptions set forth in the Indenture, (i) the
Indenture or the Securities may be amended without prior notice to any Holder
but with the written consent of the Holders of at least a majority in aggregate
principal amount of the outstanding Securities and (ii) any default may be
waived with the written consent of the Holders of at least a majority in
principal amount of the outstanding Securities. Subject to certain exceptions
set forth in the Indenture, without the consent of any Holder of Securities, the
Company and the Trustee may amend the Indenture or the Securities (i) to cure
any ambiguity, omission, defect or inconsistency; (ii) to comply with Article 5
of the Indenture; (iii) to provide for uncertificated Securities in addition to
or in place of certificated Securities; (iv) to add Note Guarantees with respect
to the Securities; (v) to secure the Securities; (vi) to add additional
covenants or to surrender rights and powers conferred on the Company; (vii) to
comply with the requirements of the SEC in order to effect or maintain the
qualification of the Indenture under the TIA; (viii) to make any change that
does not adversely affect the rights of any Holder; (ix) to make any change in
the subordination provisions of the Indenture that would limit or terminate the
benefits available to any holder of Senior Indebtedness of the Company (or any
representative thereof) under such subordination provisions; or (x) to provide
for the issuance of the Exchange Securities or Private Exchange Securities.

15.  Defaults and Remedies
     ---------------------

          If an Event of Default occurs (other than an Event of Default relating
to certain events of bankruptcy, insolvency or reorganization of the Company)
and is continuing, the Trustee or the Holders of at least 25% in principal
amount of the outstanding Securities may declare the principal of and accrued
but unpaid interest on all the Securities to be due and payable.  If an Event of
Default relating to certain events of bankruptcy, insolvency or reorganization
of the Company occurs, the principal of and interest on all the Securities shall
become immediately due and payable without any declaration or other act on the
part of the Trustee or any Holders.  Under certain circumstances, the Holders of
a majority in principal amount of the outstanding Securities may rescind any
such acceleration with respect to the Securities and its consequences.

          If an Event of Default occurs and is continuing, the Trustee shall be
under no obligation to exercise any of the rights or powers under the Indenture
at the request or direction of any of the Holders unless such Holders have
offered to the Trustee reasonable indemnity or security against any loss,
liability or expense and certain other conditions are complied with.


                                                                               9

Except to enforce the right to receive payment of principal, premium (if any) or
interest when due, no Holder may pursue any remedy with respect to the Indenture
or the Securities unless (i) such Holder has previously given the Trustee notice
that an Event of Default is continuing, (ii) Holders of at least 25% in
principal amount of the outstanding Securities have requested the Trustee in
writing to pursue the remedy, (iii) such Holders have offered the Trustee
reasonable security or indemnity reasonably satisfactory to the Trustee against
any loss, liability or expense, (iv) the Trustee has not complied with such
request within 60 days after the receipt of the request and the offer of
security or indemnity and (v) the Holders of a majority in principal amount of
the outstanding Securities have not given the Trustee a direction inconsistent
with such request within such 60-day period. Subject to certain restrictions,
the Holders of a majority in principal amount of the outstanding Securities are
given the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or of exercising any trust or
power conferred on the Trustee. The Trustee, however, may refuse to follow any
direction that conflicts with law or the Indenture or that the Trustee
determines is unduly prejudicial to the rights of any other Holder or that would
involve the Trustee in personal liability. Prior to taking any action under the
Indenture, the Trustee shall be entitled to indemnification satisfactory to it
in its sole discretion against all losses and expenses caused by taking or not
taking such action.

16.  Trustee Dealings with the Company
     ---------------------------------

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

17.  No Recourse Against Others
     --------------------------

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

18.  Authentication
     --------------

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

19.  Abbreviations
     -------------

          Customary abbreviations may be used in the name of a Holder or an
assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the
entireties), JT TEN (=joint


                                                                              10

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

20.  Governing Law
     -------------

          THIS SECURITY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH,
THE LAWS OF THE STATE OF NEW YORK 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.

21.  CUSIP and ISIN Numbers
     ----------------------

          The Company has caused CUSIP [and ISIN] numbers to be printed on the
Securities and has directed the Trustee to use CUSIP [and ISIN] 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 Securities or as
contained in any notice of redemption and reliance may be placed only on the
other identification numbers placed thereon.

          The Company will furnish to any Holder of Securities upon written
request and without charge to the Holder a copy of the Indenture which has in it
the text of this Security.


                                                                              11

Better Minerals & Aggregates Company

In care of
The Bank of New York

Ladies and Gentlemen:


     This certificate is delivered to request a transfer of $[   ] principal
amount of the 13% Senior Subordinated Notes due 2009 (the "Securities") of
Better Minerals & Aggregates Company (the "Company").

     Upon transfer, the Securities would be registered in the name of the new
beneficial owner as follows:

Name:________________________

Address:_____________________

Taxpayer ID Number:__________

     The undersigned represents and warrants to you that:

     1.   We are an institutional "accredited investor" (as defined in Rule
501(a)(1), (2), (3) or (7) under the Securities Act of 1933, as amended (the
"Securities Act")), purchasing for our own account or for the account of such an
institutional "accredited investor" at least $250,000 principal amount of the
Securities, and we are acquiring the Securities not with a view to, or for offer
or sale in connection with, any distribution in violation of the Securities Act.
We have such knowledge and experience in financial and business matters as to be
capable of evaluating the merits and risks of our investment in the Securities,
and we invest in or purchase securities similar to the Securities in the normal
course of our business.  We, and any accounts for which we are acting, are each
able to bear the economic risk of our or its investment.

     2.   We understand that the Securities have not been registered under the
Securities Act and, unless so registered, may not be sold except as permitted in
the following sentence.  We agree on our own behalf and on behalf of any
investor account for which we are purchasing Securities to offer, sell or
otherwise transfer such Securities prior to the date that is two years


                                                                               2

after the later of the date of original issue and the last date on which the
Company or any affiliate of the Company was the owner of such Securities (or any
predecessor thereto) (the "Resale Restriction Termination Date") only (a) to the
Company, (b) pursuant to a registration statement that has been declared
effective under the Securities Act, (c) in a transaction complying with the
requirements of Rule 144A under the Securities Act ("Rule 144A"), to a person we
reasonably believe is a qualified institutional buyer under Rule 144A (a "QIB")
that is purchasing for its own account or for the account of a QIB and to whom
notice is given that the transfer is being made in reliance on Rule 144A, (d)
pursuant to offers and sales that occur outside the United States within the
meaning of Regulation S under the Securities Act, (e) to an institutional
"accredited investor" within the meaning of Rule 501(a)(1), (2), (3) or (7)
under the Securities Act that is purchasing for its own account or for the
account of such an institutional "accredited investor," in each case in a
minimum principal amount of Securities of $250,000, or (f) pursuant to any other
available exemption from the registration requirements of the Securities Act,
subject in each of the foregoing cases to any requirement of law that the
disposition of our property or the property of such investor account or accounts
be at all times within our or their control and in compliance with any
applicable state securities laws. The foregoing restrictions on resale will not
apply subsequent to the Resale Restriction Termination Date. If any resale or
other transfer of the Securities is proposed to be made pursuant to clause (e)
above prior to the Resale Restriction Termination Date, the transferor shall
deliver a letter from the transferee substantially in the form of this letter to
the Company and the Trustee, which shall provide, among other things, that the
transferee is an institutional "accredited investor" within the meaning of Rule
501(a)(1), (2), (3) or (7) under the Securities Act and that it is acquiring
such Securities for investment purposes and not for distribution in violation of
the Securities Act. Each purchaser acknowledges that the Company and the Trustee
reserve the right prior to the offer, sale or other transfer prior to the Resale
Restriction Termination Date of the Securities pursuant to clause (d), (e) or
(f) above to require the delivery of an opinion of counsel, certifications or
other information satisfactory to the Company and the Trustee.
