Consolidated Interest Expense for such four fiscal quarters (determined, for the

            (1) if the Company or any Restricted Subsidiary has Incurred any
      Indebtedness since the beginning of such period that remains outstanding
      on such date of determination or if the transaction giving rise to the
      need to calculate the Consolidated Coverage Ratio is an Incurrence of
      Indebtedness, EBITDA and Consolidated Interest Expense for such period
      shall be calculated after giving effect on a pro forma basis to such
      Indebtedness and the application of the proceeds thereof 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

   15
                                                                               7


      period or increased by an amount equal to the EBITDA (if negative)
      directly attributable thereto for such period and (y) Consolidated
      Interest Expense for such period shall be reduced by an amount equal to
      the Consolidated Interest Expense directly attributable to any
      Indebtedness of the Company or any Restricted Subsidiary repaid,
      repurchased, defeased or otherwise discharged with respect to the Company
      and its continuing Restricted Subsidiaries in connection with such
      Disposal for such period (or, if the Capital Stock of any Restricted
      Subsidiary is sold, the Consolidated Interest Expense for such period
      directly attributable to the Indebtedness of such Restricted Subsidiary to
      the extent the Company and its continuing Restricted Subsidiaries are no
      longer liable for such Indebtedness after such sale);

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

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

            For purposes of this definition, whenever pro forma effect is to be
given to an acquisition of assets, the amount of income or earnings relating
thereto and the amount 
   16
                                                                               8


of Consolidated Interest Expense associated with any Indebtedness Incurred in
connection therewith, the pro forma calculations shall be determined in good
faith by a responsible financial or accounting Officer of the Company. If any
Indebtedness bears a floating rate of interest and is being given pro forma
effect, the interest expense on such Indebtedness shall be calculated as if the
rate in effect on the date of determination had been the applicable rate for the
entire period (taking into account any Interest Rate Agreement applicable to
such Indebtedness if such Interest Rate Agreement has a remaining term as at the
date of determination in excess of 12 months). If any Indebtedness bears, at the
option of the Company or a Restricted Subsidiary, a fixed or floating rate of
interest and is being given pro forma effect, then (i) if any interest had
accrued on such Indebtedness prior to the date of determination, the interest
expense on such Indebtedness shall be computed by applying a fixed or floating
rate of interest as selected by the Company or such Restricted Subsidiary for
the interest period immediately preceding such determination or (ii) if no
interest accrued on such Indebtedness prior to the date of determination, the
interest expense on such Indebtedness shall be computed by applying, at the
option of the Company or such Restricted Subsidiary, either a fixed or floating
rate. If any Indebtedness which is being given pro forma effect was Incurred
under a revolving credit facility that was in effect throughout the applicable
period, the interest expense on such Indebtedness shall be computed based upon
the average daily balance of such Indebtedness during the applicable period.

            "Consolidated Interest Expense" means, for any period, the total
consolidated interest expense of the Company and its Restricted Subsidiaries for
such period, plus, to the extent Incurred by the Company and its Restricted
Subsidiaries in such period but not included in such interest expense: (i)
interest expense attributable to Capitalized Lease Obligations and Attributable
Debt; (ii) amortization of debt discount; (iii) capitalized interest; (iv)

with respect to letters of credit and bankers' acceptance financing; (vi) net
costs associated with Interest Rate Agreements; (vii) the interest portion of
any deferred payment obligation for goods or services; (viii) interest actually
paid by the Company or any Restricted Subsidiary on any Indebtedness of any
other Person that is Guaranteed by the Company or any Restricted Subsidiary;

contributions are used by such plan or trust to pay interest or fees to any
Person (other than the Company or a Wholly Owned Subsidiary) in connection with

included in Consolidated Net Income); but in no event shall include (i)
amortization of debt issuance costs; (ii) Preferred Stock dividends in respect
of all Preferred Stock of Subsidiaries of the Company and Disqualified Stock of

operations.

      Restricted Subsidiary, except that (A) subject to the limitations
      contained in clause (iv) below, the Company's equity in the net income of
      any such Person for such period shall be included in such Consolidated Net
      Income up to the aggregate amount of cash actually distributed by such
      Person during such period to the Company or a Restricted Subsidiary as a
      dividend or other distribution (subject, in the case of a dividend or
      other distribution to a Restricted Subsidiary, to the limitations
      contained in clause (iii) below) and (B) the Company's equity in a net
      loss of any such Person (other than an Unrestricted Subsidiary) for such
      period shall be included in determining such Consolidated Net Income;

            (ii) for purposes of Section 4.04(a)(3)(A) only, any net income
      (loss) of any person acquired by the Company or a Subsidiary in a pooling
      of interests transaction for any period prior to the date of such
      acquisition;

            (iii) any net income (loss) of any Restricted Subsidiary if such
      Subsidiary is subject to restrictions, directly or indirectly, on the
      payment of dividends or the making of distributions by such Restricted
      Subsidiary, directly or indirectly, to the Company, except that (A)
      subject to the limitations contained in (iv) below, the Company's equity
      in the net income of any such Restricted Subsidiary for such period shall
      be included in such Consolidated Net Income up to the aggregate amount of

      have been distributed by such Restricted Subsidiary during such period to
      the Company or another Restricted Subsidiary as a dividend (subject, in
      the case of a dividend that could have been made to another Restricted
      Subsidiary, to the limitation contained in this clause) and (B) the
      Company's equity in a net loss of any such Restricted Subsidiary for such
      period shall be included in determining such Consolidated Net Income;

            (iv) any gain (or loss) realized upon the sale or other disposition
      of any asset of the Company or its Consolidated Subsidiaries (including
      pursuant to any Sale/Leaseback Transaction) which is not sold or otherwise
      disposed of in the ordinary course of business and any gain (or loss)
      realized upon the sale or other disposition of any Capital Stock of any

rules regarding the maximum principal amount to be represented by a single
certificate) will represent Initial Securities sold to QIBs (the "QIB Global
Note"), and the other will represent Initial Securities sold to IAIs (the "IAI
Global Note"). The aggregate principal amount of each U.S. Global Security may
from time to time be increased or decreased by adjustments made on the records
of the Trustee, as custodian for the Depositary or its nominee, as hereinafter

            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 deliver (1) Initial Securities
for original issue in an aggregate principal amount of $150,000,000 and (2)
Exchange Securities for issue only in a Registered Exchange Offer, pursuant to
the Exchange and Registration Rights Agreement, for Initial Securities for a
like principal amount of Initial Securities exchanged pursuant thereto, in each
case upon a written order of the Company signed by two Officers or by an Officer
and either an Assistant Treasurer or an Assistant Secretary of the Company. Such
order shall specify the amount of the Securities to be authenticated, the date
on which the original issue of Securities is to be authenticated and whether the
Securities are to be Initial Securities or Exchange Securities. The aggregate
principal amount of Securities outstanding at any time may not exceed
$150,000,000 except as provided in Section 2.07.

            The Trustee may appoint an authenticating agent reasonably
acceptable to the Company to authenticate the Securities. Any such appointment

Trustee, 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.

any Registrar, Paying Agent or co-registrar 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 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 incorporated Wholly Owned Subsidiaries may
act as Paying Agent, Registrar, co-registrar or transfer agent.

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

            The Company initially appoints The Depository Trust Company to act
as Depositary with respect to the Global Securities.

            The Company may remove any Registrar or Paying Agent upon written
notice to such Registrar or Paying Agent and to the Trustee; provided that no
such removal shall become effective until (1) 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 (2) notification to the Trustee that the Trustee shall serve
as Registrar or Paying Agent until the appointment of a successor in accordance
with clause (1) above. The Registrar or Paying Agent may resign at any time upon
written notice; provided, however, that the Trustee may 
   44
                                                                              36


resign as Paying Agent or Registrar only if the Trustee also resigns as Trustee
in accordance with Section 7.08.

            SECTION 2.04. Paying Agent To Hold Money in Trust. 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
Securityholders or the Trustee all money held by the Paying Agent for the
payment of principal of or interest on the Securities and shall notify the
Trustee of any default by the Company in making any such payment. If the Company
or a Subsidiary 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.

            Any money deposited with any Paying Agent, or then held by the
Company or a Subsidiary in trust for the payment of principal or interest on any
Security and remaining unclaimed for two years after such principal and interest
has become due and payable shall be paid to the Company at its request, or, if
then held by the Company or a Subsidiary, shall be discharged from such trust;
and the Securityholders shall thereafter, as unsecured general creditors, look
only to the Company for payment thereof, and all liability of the Paying Agent
with respect to such money, and all liability of the Company or such Subsidiary
as trustee thereof, shall thereupon cease.

            SECTION 2.05. Securityholder 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 Securityholders. 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 Securityholders.

   45
                                                                              37


            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. When a Security is presented to the
Registrar or a co-registrar with a request to register a transfer, the Registrar
shall register the transfer as requested if the requirements of Section 8-401(l)
of the Uniform Commercial Code are met. When Securities are presented to the
Registrar or a co-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 or co-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 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 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 Trustee, the Paying Agent, the Registrar or any
co-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, if any, 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, the Registrar or any co-registrar shall
be affected by notice to the contrary.

            Any Holder of a U.S. Global Security shall, by acceptance of such
Global Note, agree that transfers of beneficial interest in such Global Security
may be effected only through a book-entry system maintained by the Holder of
such Global Security (or its agent), 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 this
Section 2.06 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.

   46
                                                                              38


            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 (i)
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, (ii) makes such
request to the Company or the Trustee prior to the Security being acquired by a
bona fide purchaser and (iii) satisfies any other reasonable requirements of the
Trustee. 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, the Registrar and any co-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.

            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. 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 bona fide 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 
   47
                                                                              39


interest 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 Securityholders 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.

            In determining whether the Holders of the required principal amount
of Securities have concurred in any direction, waiver or consent, Securities
owned by the Company or any of its Affiliates shall be disregarded, except that,
for the purposes of determining whether the Trustee shall be protected in
relying on any such direction, waiver or consent, only Securities which the
Trustee knows or has reason to know are so owned shall be disregarded.

            SECTION 2.09. Temporary Securities. Until Definitive Securities and
Global 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 and
destroy (subject to the record retention requirements of the Exchange Act) all
Securities surrendered for registration of transfer, exchange, payment or
cancelation unless the Company directs the Trustee to deliver canceled
Securities to the Company. 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
interest (plus interest on such defaulted interest to the extent lawful) in any
lawful 
   48
                                                                              40


manner. The Company may pay the defaulted interest to the persons who are
Securityholders 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 Securityholder a notice that states the special record date, the
payment date and the amount of defaulted interest to be paid.

            The Company may make payment of any defaulted interest in any other
lawful manner not inconsistent with the requirements (if applicable) of any
securities exchange on which the Securities may be listed, and upon such notice
as may be required by such exchange, if, after notice given by the Company to
the Trustee of the proposed payment pursuant to this paragraph, such manner of
payment shall be deemed practicable by the Trustee.

            SECTION 2.12. CUSIP Numbers. The Company in issuing the Securities
may use "CUSIP" numbers (if then generally in use) and, if so, the Trustee shall
use "CUSIP" numbers in notices of redemption as a convenience to Holders;
provided, 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.

            SECTION 2.13. Book-Entry Provisions for U.S. Global Security.

            (a) Each U.S. Global Security initially shall (i) be registered in
the name of the Depositary for such U.S. Global Security or the nominee of such
Depositary and (ii) be delivered to the Trustee as custodian for such
Depositary.

            Members of, or participants in, the Depositary ("Agent Members")
shall have no rights under this Indenture with respect to any U.S. Global
Security held on their behalf by the Depositary, or the Trustee as its
custodian, or under such U.S. Global Security, and the Depositary may be treated
by the Company, the Trustee and any agent of the Company or the Trustee as the
absolute owner of such U.S. Global Security for all purposes whatsoever.
Notwithstanding the foregoing, nothing herein shall prevent the Company, the
Trustee or any agent of the Company or the Trustee from giving effect to any
written certification, 
   49
                                                                              41


proxy or other authorization furnished by the Depositary or shall impair, as
between the Depositary and its Agent Members, the operation of customary
practices governing the exercise of the rights of a Holder of any Security.

            (b) Transfers of a U.S. Global Security shall be limited to
transfers of such U.S. Global Security in whole, but not in part, to the
Depositary, its successors or their respective nominees. Interests of beneficial
owners in a U.S. Global Security may be transferred in accordance with the rules
and procedures of the Depositary and the provisions of Section 2.14. If required
to do so pursuant to any applicable law or regulation, beneficial owners may
obtain U.S. Physical Securities in exchange for their beneficial interests in a
U.S. Global Security upon written request in accordance with the Depositary's
and the Registrar's procedures. In addition, U.S. Physical Securities shall be
transferred to all beneficial owners in exchange for their beneficial interests
in a U.S. Global Security if (i) the Depositary notifies the Company that it is
unwilling or unable to continue as Depositary for such U.S. Global Security or
the Depositary ceases to be a clearing agency registered under the Exchange Act,
at a time when the Depositary is required to be so registered in order to act as
Depositary, and in each case a successor depositary is not appointed by the
Company within 90 days of such notice or, (ii) the Company executes and delivers
to the Trustee and Security Registrar an Officers' Certificate stating that such
U.S. Global Security shall be so exchangeable or (iii) an Event of Default has
occurred and is continuing and the Registrar has received a request from the
Depositary.

            (c) In connection with any transfer of a portion of the beneficial
interest in a U.S. Global Security pursuant to subsection (b) of this Section to
beneficial owners who are required to hold U.S. Physical Securities, the
Registrar shall reflect on its books and records the date and a decrease in the
principal amount of such U.S. Global Security in an amount equal to the
principal amount of the beneficial interest in the U.S. Global Security to be
transferred, and the Company shall execute, and the Trustee shall authenticate
and deliver, one or more U.S. Physical Securities of like tenor and amount.

            (d) In connection with the transfer of an entire U.S. Global
Security to beneficial owners pursuant to subsection (b) of this Section, such
U.S. Global Security shall be deemed to be surrendered to the Trustee for
cancelation, and the Company shall execute, and the Trustee 
   50
                                                                              42


shall authenticate and deliver, to each beneficial owner identified by the
Depositary in exchange for its beneficial interest in such U.S. Global Security,
an equal aggregate principal amount of U.S. Physical Securities of authorized
denominations.

            (e) Any U.S. Physical Security delivered in exchange for an interest
in a U.S. Global Security pursuant to subsection (c) or subsection (d) of this
Section shall, except as otherwise provided by paragraph (f) of Section 2.14,
bear the applicable legend regarding transfer restrictions applicable to the
U.S. Physical Security set forth in Exhibit A.

            (f) The registered holder of a U.S. 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.

            SECTION 2.14. Special Transfer Provisions.

            Unless and until an Initial Security is transferred or exchanged
under an effective registration statement under the Securities Act, the
following provisions shall apply:

            (a) Transfers to Non-QIB Institutional Accredited Investors. The
following provisions shall apply with respect to the registration of any
proposed transfer of an Initial Security to any IAI which is not a QIB

      Security if (x) the requested transfer is at least two years after the

      has delivered to the Registrar a certificate substantially in the form set
      forth in Exhibit C.

      interest in the QIB Global Security, upon receipt by the Registrar of (x)
      the document, if any, required by paragraph (i) and (y) instructions given
      in accordance with the Depositary's and the Registrar's procedures
      therefor, the Registrar shall reflect on its books and records 
   51
                                                                              43

      the date and an increase in the principal amount of the IAI Global
      Security in an amount equal to (x) the principal amount of the U.S.
      Physical Securities to be transferred, and the Trustee shall cancel the
      U.S. Physical Security so transferred or (y) the amount of the beneficial
      interest in the QIB Global Security to be so transferred (in which case
      the Registrar shall reflect on its books and records the date and an
      appropriate decrease in the principal amount of the QIB Global Security).

            (iii) If the proposed transferee is entitled to receive a U.S.
      Physical Security as provided in Section 2.13 and the proposed transferor
      is an Agent Member holding a beneficial interest in a U.S. Global
      Security, upon receipt by the Registrar of (x) the documents, if any,
      required by paragraph (i) and (y) instructions given in accordance with
      the Depositary's and the Registrar's procedures therefor, the Registrar

      principal amount of such U.S. Global Security in an amount equal to the
      principal amount of the beneficial interest in such U.S. Global Security
      to be transferred, and the Company shall execute, and the Trustee shall
      authenticate and deliver, one or more U.S. Physical Securities of like
      tenor and amount.

            (iv) If the Initial Security to be transferred consists of U.S.

      Registrar of the document, if any, required by paragraph (i), the
      Registrar shall register such transfer and the Company shall execute, and

      Securities of like tenor and amount.

            (b) Transfers to QIBs. The following provisions shall apply with
respect to the registration of any proposed transfer of an Initial Security to a
QIB (excluding Non-U.S. Persons):

            (i) If the Security to be transferred consists of U.S. Physical
      Securities, Temporary Offshore Physical Securities, Permanent Offshore
      Physical Securities or an interest in the IAI Global Security, the
      Registrar shall register the transfer if such transfer is being made by a
      proposed transferor who has provided the 
   52
                                                                              44

      therefor, the Registrar shall reflect on its books and records the date
      and an increase in the principal amount of the QIB Global Security in an
      amount equal to (x) the principal amount of the U.S. Physical Securities,
      Temporary Offshore Physical Securities or Permanent Offshore Physical
      Securities, as the case may be, to be transferred, and the Trustee shall
      cancel the Physical Security so transferred or (y) the amount of the
      beneficial interest in the IAI Global Security to be so transferred (in
      which case the Registrar shall reflect on its books and records the date
      and an appropriate decrease in the principal amount of the IAI Global
      Security).

            (iii) If the proposed transferee is entitled to receive a U.S.
      Physical Security as provided in Section 2.13 and the proposed transferor
      is an Agent Member holding a beneficial interest in a U.S. Global
      Security, upon receipt by the Registrar of (x) the documents, if any,
      required by paragraph (i) and (y) instructions given in accordance with
      the Depositary's and the Registrar's procedures therefor, the Registrar
      shall reflect on its books and records the date and a decrease in the

      tenor and amount.

            (iv) If the Initial Security to be transferred consists of U.S.
      Physical Securities, Temporary Offshore Physical Securities or Permanent
      Offshore Physical Securities and the proposed transferee is entitled to
      receive a U.S. Physical Security as provided in Section 2.13, upon receipt
      by the Registrar of the document, if any, required by paragraph (i), the

   53
                                                                              45


      Registrar shall register such transfer and the Company shall execute, and

      Company shall execute, and the Trustee shall authenticate and deliver, one

            (f) Private Placement Legend. Upon the transfer, exchange or
replacement of Securities not bearing the Private Placement Legend, the

                                   ARTICLE III

                                   Redemption

            SECTION 3.01. Notices to Trustee. If the Company elects to redeem
Securities pursuant to Section 3.07, it shall notify the Trustee in writing of
the redemption date and the principal amount of Securities 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; provided, however, that an
Opinion of Counsel shall not be required in connection with a redemption
pursuant to Section 3.07. If fewer than all the Securities are to be redeemed,
the record date relating to such redemption shall be selected by the Company and
given to the Trustee, which record date shall be not less than 15 days after the
date of notice to the Trustee (unless a shorter period shall be acceptable to
the Trustee). Any such notice may be canceled by notice in writing to the
Trustee at any time prior to notice of such redemption being mailed to any
Holder 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 a method that complies with applicable
legal and securities exchange requirements, if any, and that the Trustee
considers fair and appropriate and in accordance with methods generally used at
the time of selection by fiduciaries in similar circumstances. The Trustee shall
make the selection from outstanding 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. At least 30 days but not more
than 60 days before a date for redemption of Securities, the Company shall mail
a notice of 
   57
                                                                              49


redemption by first-class mail to each Holder of Securities to be redeemed.

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

            (1) the redemption date;

            (2) the redemption price;

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

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

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

            (6) 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;

            (7) the CUSIP number, if any, printed on the Securities being
      redeemed;

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

            (9) that if a Security is to be redeemed in part, only the portion
      of the principal amount (equal to $1,000 or an integral multiple thereof)
      of such Security to be redeemed and that a new Security in the aggregate
      principal amount equal to the unredeemed portion thereof will be issued
      without charge to the holder.

            At the Company's request (which may be revoked at any time in
writing prior to the time at which the Trustee shall have given such notice to
the Holders), 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.

   58
                                                                              50


            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, if any, to the redemption
date; provided that if the redemption date is after a regular record date and on
or prior to the interest payment date, the accrued interest shall be payable to
the Securityholder of the redeemed Securities registered on the relevant record
date. If mailed in the manner provided herein, the notice shall be conclusively
presumed to have been given whether or not the Holder receives such notice.
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. At least one Business Day
prior to the redemption date, the Company shall deposit with the Paying Agent
(or, if the Company or a Subsidiary is the Paying Agent, shall segregate and
hold in trust) money sufficient to pay the redemption price of and accrued
interest on all Securities to be redeemed on that date other than Securities or
portions of Securities called for redemption which have been delivered by the
Company to the Trustee for cancelation.

            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.

            SECTION 3.07. Optional Redemption. (a) Except as set forth in the
next two paragraphs, the Securities may not be redeemed prior to May 1, 2002. On

at any time at the following redemption prices (expressed in percentages of
principal amount), plus accrued and unpaid interest, if any, to the redemption
date (subject to the right of Holders of record on the relevant record

Period                                                                   Price  
- ------                                                                ----------

2005 and thereafter  ...........................................      100.0000% 

            (b) Notwithstanding the foregoing, at any time on or prior to May 1,
2000, the Company may redeem in the aggregate up to 40% of the original
aggregate principal amount of Securities with the proceeds of one or more Public
Equity Offerings following which there is a Public Market, at a redemption price
(expressed as a percentage of principal amount thereof) of 111.125% plus accrued
and unpaid interest, 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 that is on or prior to the date of redemption);
provided, however, that at least 60% of the original aggregate principal amount
of the Securities must remain outstanding after each such redemption.

redeemed, in whole or in part, at any time within 180 days after a Change of
Control, at a redemption price equal to the sum of (i) the principal amount
thereof plus (ii) accrued and unpaid interest, 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 that is on or prior

one such provision and in part by one or more other provisions of this provision
permitting such Indebtedness and (ii) in the event that Indebtedness or any
portion thereof meets the criteria of more than one of the types of Indebtedness
described in this section, 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.

retirement, Investment or payment being herein referred to as a "Restricted
Payment") if at the time the Company or such Restricted Subsidiary makes such
Restricted Payment:

      therefrom);

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

      Directors) declared or made subsequent to the Issue Date would exceed the

      that the encumbrances and restrictions contained in (A) any such
      refinancing agreement or amendment referred to in clause (x) above are,
      collectively, no more restrictive in any material respect, than the

      or of any lease;

            (7) any encumbrance or restriction contained in contracts for sales
      of assets otherwise permitted by this Indenture;

            (8) with respect to a Restricted Subsidiary, any encumbrance or
      restriction imposed pursuant to an agreement that has been entered into

            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, as
may be determined (and shall be determined, to the extent an Asset Disposition
(or a series of related Asset Dispositions) involves a fair market value greater
than $1,000,000) in good faith by the Board of Directors, whose determination
shall be conclusive and evidenced by a resolution of the Board of Directors
(including as to the value of all non-cash consideration), of the shares and
assets subject to such Asset Disposition, (ii) in the case of an Asset
Disposition (or a series of related Asset Dispositions) having a fair market
value of $1,000,000 or more at least 80% (or 100% in the case of lease payments)
of the consideration thereof received by the Company or such Restricted
Subsidiary is in the form of cash or cash equivalents 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) (A) first, to the
extent the Company or such Restricted Subsidiary elects (or is required by the
terms of any Senior Indebtedness), to prepay, repay or purchase Senior
Indebtedness of the Company or a Wholly Owned Subsidiary or, in the case of a
sale by a Restricted Subsidiary which is 
   71
                                                                              63


not a Wholly Owned Subsidiary, to prepay, repay or purchase Senior Indebtedness
of such Restricted Subsidiary (in each case other than Indebtedness owed to the
Company or an Affiliate of the Company) within 365 days after the later of the
date of such Asset Disposition or the receipt of such Net Available Cash; (B)
second, to the extent of the balance of Net Available Cash after application in
accordance with clause (A), to the extent the Company or such Restricted
Subsidiary elects, to reinvest (or enter into a binding contract to do so) 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 365 days from the later of such Asset Disposition
or the receipt of such Net Available Cash; (C) third, to the extent of the
balance of such Net Available Cash after application in accordance with clauses
(A) and (B), to make an Offer (as defined below) to purchase Securities pursuant
to and subject to the conditions of Section 4.06(b) and (D) fourth, to the
extent of the balance of such Net Available Cash after application in accordance
with clauses (A), (B) and (C), to fund (to the extent consistent with any other
applicable provision of this Indenture) any corporate purpose; provided,
however, that in connection with any prepayment, repayment or purchase of
Indebtedness pursuant to clause (A) 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 or purchased. Notwithstanding the foregoing
provisions of this covenant, the Company and its Restricted Subsidiaries shall
not be required to apply any Net Available Cash in accordance with this covenant
except to the extent that the aggregate Net Available Cash from all Asset
Dispositions in any year which are not applied in accordance with this covenant
exceed $5,000,000 in such year.

            For the purposes of Section 4.06(a)(ii), the following are deemed to
be cash: (w) the assumption of Indebtedness of the Company (other than
Disqualified Stock of the Company) or any Restricted Subsidiary and the release
of the Company or such Restricted Subsidiary from all liability on such
Indebtedness in connection with such Asset Disposition, (x) 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, (y)
Indebtedness of any Restricted Subsidiary that is no longer a Restricted
Subsidiary as a result of such Asset Disposition, to the extent that the Company
and each other Restricted Subsidiary is released from any Guarantee of such

   72
                                                                              64


Indebtedness in connection with such Asset Disposition, and (z) consideration
consisting of Indebtedness of the Company or any Restricted Subsidiary.

            (b) In the event of an Asset Disposition that requires the purchase
of Securities pursuant to Section 4.06(a)(iii)(C), the Company shall be required
to purchase Securities tendered pursuant to an offer, commenced within 30 days
following the expiration of the 365 day period referred to in Section
4.06(a)(iii)(B) (or, if the Company so elects, at any time within such 365 day
period), by the Company for the Securities (the "Offer") at a purchase price of
100% of their principal amount plus accrued and unpaid interest, if any, to the
date of purchase in accordance with the procedures (including prorationing in
the event of oversubscription) set forth in Section 4.06(c). If the aggregate
purchase price of Securities tendered pursuant to the Offer is less than the Net
Available Cash allotted to the purchase of the Securities, the Company shall
apply the remaining Net Available Cash in accordance with Section
4.06(a)(iii)(D) and upon completion of the purchase of the Notes tendered
pursuant to the Offer, the remaining amount of Net Available Cash, if any, will
be reset at zero. The Company shall not be required to make an Offer for
Securities pursuant to this Section if the Net Available Cash available therefor
(after application of the proceeds as provided in clauses (A) and (B) of Section
4.06(a)(iii)) is less than $5,000,000 (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)(1) Promptly, and in any event within 10 days after the Company
becomes obligated to make an Offer, the Company shall 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 prorationing 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 will include (i) 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 
   73
                                                                              65


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), (ii) a
description of material developments in the Company's business subsequent to the
date of the latest of such Reports, and (iii) if material, appropriate pro forma
financial information) and all instructions and materials necessary to tender
Securities pursuant to the Offer, together with the information contained in
clause (3).

            (2) Not later than the date upon which written notice of an Offer is
delivered to the Trustee as provided below, the Company shall deliver to the
Trustee an Officers' Certificate as to (i) the amount of the Offer (the "Offer
Amount"), (ii) the allocation of the Net Available Cash from the Asset
Dispositions pursuant to which such Offer is being made and (iii) 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) in Temporary Cash Investments an amount equal to the Offer Amount 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 which have been properly tendered to and are to be accepted by
the Company. The Trustee (or paying agent) shall, on the Purchase Date, mail or
deliver payment to each tendering Holder in the amount of the purchase price. In
the event that the aggregate purchase price of the Securities delivered by the
Company to the Trustee is less than the Offer Amount, the Trustee (or paying
agent) shall deliver the excess to the Company (or if the Company is acting as
paying agent, the Company may release such amount from trust) promptly after the
expiration of the Offer Period for application in accordance with this Section.

            (3) Holders electing to have a Security purchased will be required
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 will be entitled to withdraw their election
if the Trustee or the Company receives not later than 5:00 PM Eastern Standard
Time one Business Day prior to the Purchase Date, a telegram, telex, facsimile
transmission or letter setting forth the name of the Holder, the principal
amount of the Security which was delivered for 
   74
                                                                              66


purchase by the Holder and a 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 surrendered by Holders
exceeds the Offer Amount, the Company shall select the Securities to be
purchased on a pro rata basis (with such adjustments as may be deemed
appropriate by the Company so that only Securities 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.

            (4) 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 and an Opinion of Counsel 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.

            (d) 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. To the extent that the provisions of any securities laws or regulations
conflict with provisions of this Section, the Company shall comply with the
applicable securities laws and regulations and shall not be deemed to have
breached its obligations under this Section 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 (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") on terms (i) that are
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 not such an Affiliate and (ii) that,
in the event such Affiliate Transaction involves an aggregate amount in excess
of $1,000,000, are not in writing and have not been approved by a majority of
the members of the Board of Directors having no material direct or indirect
financial interest in or with respect to such Affiliate Transaction. 
   75
                                                                              67


In addition, if such Affiliate Transaction involves an amount in excess of
$5,000,000, a fairness opinion must be obtained from a nationally recognized
appraisal or investment banking firm.

            (b) The provisions of Section 4.07(a) shall not prohibit (i) any
Restricted Payment or Permitted Investment permitted to be made pursuant to
Section 4.04, (ii) fees, compensation or employee benefit arrangements paid to,
and any indemnity provided for the benefit of directors, officers or employees

and ratably with (or on a senior basis to, in the case of Indebtedness

all or substantially all its assets to any Person unless:

            (i) the resulting, surviving or transferee Person (the "Successor
      Company") shall be a corporation organized and existing under the laws of
      the United States of America, any State thereof or the District of
      Columbia and the Successor Company (if not the Company) shall expressly
      assume, by an indenture supplemental hereto, executed and delivered to the
      Trustee, in form satisfactory to the Trustee, all the obligations of the
      Company under the Securities and this Indenture;

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

            (iii) except in the case of a merger the sole purpose of which is to
      change the Company's jurisdiction of incorporation, immediately after

      Incur an additional $1.00 of Indebtedness under Section 4.03(a);

            (iv) immediately after giving effect to such transaction, the

      to such transaction; and

      Certificate and an Opinion of Counsel, each stating that such

            Notwithstanding the foregoing clauses (ii), (iii) and (iv), any
Restricted Subsidiary may consolidate with, merge into or transfer all or part
of its properties and assets to the Company.

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

            (3) the Company fails to comply with Section 5.01;

   81
                                                                              73


            (4) the Company fails to comply with Section 4.02, 4.03, 4.04, 4.05,
      4.06, 4.07, 4.08, 4.11, 4.12, 4.13, 4.14 or 4.15 (other than a failure to

      accelerated exceeds $5,000,000 or its foreign currency equivalent at the
      time;

            (7) the Company or any Restricted Subsidiary pursuant to or within
      the meaning of any Bankruptcy Law:

                  (A) commences a voluntary case;

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

   82
                                                                              74

            (9) the rendering of any judgment or decree for the payment of money

      or decree or (B) such judgment or decree remains outstanding the later of
      (i) the day which is the sixtieth day after the judgment is rendered and
      (ii) the day on which any right to appeal expires; or

            (10) any Subsidiary Guaranty ceases to be in full force and effect
      (except as contemplated by the terms thereof) or any Guarantor Subsidiary
      shall deny or disaffirm its obligations under this Indenture or any
      Subsidiary Guaranty and such Default continues for 10 days.

            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 (4) or (5) is not an Event of Default until
the Trustee or the Holders of at least 25% in principal amount of the
outstanding Securities notify the Company of the Default and the Company does
not cure such Default within the time specified in clauses (4) or (5) hereof
after receipt of such notice. Such notice must 
   83
                                                                              75


specify the Default, demand that it be remedied and state that such notice is a
"Notice of Default."

            The Company shall deliver to the Trustee, within 30 days after the
occurrence thereof, written notice in the form of an Officers' Certificate of
any Event of Default under clause (3), (6), (7) or (10) and any event which with
the giving of notice or the lapse of time would become an Event of Default under
clause (4), (5), (8) or (9), 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(7) or 6.01(8) with respect to the
Company) occurs and is continuing, the Trustee by notice to the Company, or the
Holders of at least 25% in principal amount of the 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(7) or 6.01(8) with respect to
the Company occurs and is continuing, 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 Securityholders.
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 Securityholder 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 acquies-

   84
                                                                              76


cence 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 (i) a Default in the payment of the
principal of or interest on a Security or (ii) a Default in respect of a
provision that under Section 9.02 cannot be amended without the consent of each
Securityholder 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 outstanding 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 Securityholders or would involve the Trustee in personal
liability; provided, however, that the Trustee may take any other action deemed
proper by the Trustee that is not inconsistent with such direction. Prior to
taking any action hereunder, the Trustee shall be entitled to indemnification
satisfactory to it in its sole discretion against all losses and expenses caused
by taking or not taking such action.

            SECTION 6.06. Limitation on Suits. A Securityholder may not pursue
any remedy with respect to this Indenture or the Securities unless:

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

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

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

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

   85
                                                                              77


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

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

            SECTION 6.07. Rights of Holders to Receive Payment. Notwithstanding
any other provision of this Indenture, the right of any Holder to receive
payment of principal of and interest on the Securities held by such Holder, on
or after the respective due dates expressed in the Securities, or to bring suit
for the enforcement of any such payment on or after such respective dates, shall
not be impaired or affected without the consent of such Holder.

            SECTION 6.08. Collection Suit by Trustee. If an Event of Default
specified in Section 6.01(1) or 6.01(2) occurs and is continuing, the Trustee
may recover judgment in its own name and as trustee of an express trust against
the Company for the whole amount then due and owing (together with interest on
any unpaid interest to the extent lawful) and the amounts provided for in
Section 7.07.

            SECTION 6.09. Trustee May File Proofs of Claim. The Trustee may file
such proofs of claim and other papers or documents and take such other actions,
including participating as a member, voting or otherwise, of any committee of
creditors appointed in the matter, as may be necessary or advisable in order to
have the claims of the Trustee and the Securityholders allowed in any judicial
proceedings relative to the Company, any Subsidiary, their respective creditors
or their property and, unless prohibited by law or applicable regulations, may
vote on behalf of the Holders in any election of a trustee in bankruptcy or
other Person performing similar functions, and any Custodian in any such
judicial proceeding is hereby authorized by each Holder to make payments to the
Trustee and, in the event that the Trustee shall consent to the making of such
payments directly to the Holders, to pay to the Trustee any amount due it for
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and its counsel, and any other amounts due the Trustee under
Section 7.07.

            Nothing herein shall be deemed to empower the Trustee to authorize
or consent to, or accept or adopt on behalf of any Securityholder, any plan of
reorganization, 
   86
                                                                              78


arrangement, adjustment or composition affecting the Securities or the rights of
any Securityholder, or to authorize the Trustee to vote in respect of the claim
of any Securityholder in any such proceeding.

            SECTION 6.10. Priorities. If the Trustee collects any money or
property from the Company pursuant to this Article VI, it shall pay out the
money or property in the following order:

            FIRST: to the Trustee for amounts due under Section 7.07;

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

            THIRD: to the Company.

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

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

            SECTION 6.12. Waiver of Stay or Extension Laws. The Company (to the
extent it may lawfully do so) shall not at any time insist upon, or plead, or in
any manner whatsoever claim or take the benefit or advantage of, any stay or
extension law wherever enacted, now or at any time hereafter in force, which may
affect the covenants or the performance of this Indenture; and the Company (to
the extent that it 
   87
                                                                              79


may lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and shall not hinder, delay or impede the execution of any power herein
granted to the Trustee, but shall suffer and permit the execution of every such
power as though no such law had been enacted.

            SECTION 6.13. Restoration of Rights and Remedies. If the Trustee or
any Securityholder has instituted any proceeding to enforce any right or remedy
under this Indenture and such proceeding has been discontinued or abandoned for
any reason, or has been determined adversely to the Trustee or to such
Securityholder, then, and in every such case, subject to any determination in
such proceeding, the Company, the Trustee and the Securityholders shall be
restored severally and respectively to their former positions hereunder and
thereafter all rights and remedies of the Company, Trustee and Securityholders
shall continue as though no such proceeding had been instituted.

                                   ARTICLE VII

                                     Trustee

            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 its
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:

            (1) 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

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

   88
                                                                              80


            (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:

            (1) this paragraph does not limit the effect of paragraph (b) of
      this Section and Section 7.02(e);

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

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

            (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.

            (e) The Trustee shall not be liable for interest on any money
received by it except as the Trustee may agree in writing with the Company.

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

            (g) No provision of this Indenture shall require the Trustee to
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.

            (h) Every provision of this Indenture relating to the conduct or
affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Section and to the provisions of the TIA.

            SECTION 7.02. Rights of Trustee. Subject to Section 7.01: (a) The
Trustee may conclusively rely on any document believed by it to be genuine and
to have been signed or presented by the proper person. The Trustee need not
investigate any fact or matter stated in the document.

            (b) Before the Trustee acts or refrains from acting, it may require
an Officers' Certificate or an Opin-

   89
                                                                              81


ion of Counsel. The Trustee shall not be liable for any action it takes or omits
to take in good faith in reliance on the Officers' Certificate or Opinion of
Counsel.

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

            (d) The Trustee shall not be liable for any action it takes or omits
to take in good faith 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, 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 protection from
liability in respect to any action taken, omitted or suffered by it hereunder
in good faith and in accordance with the advice or opinion of such counsel.

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

            (g) The Trustee shall not be bound to make any investigation into
the facts or matters stated in any document, but the Trustee, in its discretion,
may make such further inquiry or investigation into such facts or matters as it
may see fit.

            SECTION 7.03. Individual Rights of Trustee. The Trustee in its
individual or any other capacity may become the owner or pledgee of Securities
and may otherwise deal with the Company or its Affiliates with the same rights
it would have if it were not Trustee. Any Paying Agent, Registrar, co-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 or the Securities, it shall not be accountable for the Company's
use of the proceeds from the Securities, it will not be responsible 
   90
                                                                              82


for the use or application of any monies received by a Paying Agent other than
the Trustee, and it shall not be responsible for any statement of the Company 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.

            SECTION 7.05. Notice of Defaults. If a Default occurs and is
continuing and if it is known to a Trust Officer of the Trustee, the Trustee
shall mail to each Securityholder notice of the Default within the earlier of 90
days after it occurs or 30 days after it is known to a Trust Officer or written
notice of it is received by the Trustee. Except in the case of a Default in
payment of principal of, premium (if any) or interest on any Security (including
payments pursuant to the mandatory redemption provisions of such Security, if
any), the Trustee may withhold the notice if and so long as a committee of its
Trust Officers in good faith determines that withholding the notice is in the
interests of Securityholders.

            SECTION 7.06. Reports by Trustee to Holders. As promptly as
practicable after each May 15 beginning with May 15, 1998, and in any event
prior to July 15 in each year, the Trustee shall mail to each Securityholder a
brief report dated as of May 15 that complies with TIA ss. 313(a) (but if no
event described in TIA ss. 313(a) has occurred within the twelve months
preceding the reporting date, no report shall be transmitted). The Trustee will
also comply with TIA ss. 313(b) and TIA ss. 313(c).

            A copy of each report at the time of its mailing to Securityholders
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, Paying Agent and Registrar from time to time reasonable
compensation 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 other professionals. Any costs and expenses associated
with 
   91
                                                                              83


the Exchange Securities shall be paid by the Company. The Company shall
indemnify the Trustee, Paying Agent, Registrar, and each of their officers,
directors and employees (each in their respective capacities), for and hold each
of them harmless against any and all loss, liability or expense (including
attorneys' fees) incurred by them without negligence or bad faith on their part
in connection with the administration of this trust and the performance of their
duties hereunder, including the costs and expenses of defending itself against
any claim or liability in connection with the acceptance, exercise or
performance of any of its powers or duties hereunder. The Trustee, Paying Agent
and Registrar shall notify the Company of any claim for which they may seek
indemnity promptly upon obtaining actual knowledge thereof; provided that any
failure so to notify the Company shall not relieve the Company of its indemnity
obligations hereunder except to the extent the Company shall have been adversely
affected thereby. 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 shall pay the
fees and expenses of such counsel; provided 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 such parties in connection with
such defense. The Company need not pay for any settlement made without its
written consent. 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 on particular Securities.

            The Company's payment obligations pursuant to this Section shall
survive the discharge of this Indenture. When the Trustee, Paying Agent or
Registrar incurs expenses after the occurrence of a Default specified in Section
6.01(7) or 6.01(8) with respect to the Company, the expenses are intended to
constitute expenses of administration under the Bankruptcy Law.

            SECTION 7.08. Replacement of Trustee. The Trustee may resign at any
time by so notifying the Company 
   92
                                                                              84


in writing. The Holders of a majority in principal amount of the Securities may
remove the Trustee by so notifying the Company and the Trustee and may appoint a
successor Trustee with the consent of the Company, which shall not be
unreasonably withheld. The Company shall remove the Trustee if:

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

            (2) the Trustee is adjudged bankrupt or insolvent;

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

            (4) the Trustee otherwise becomes incapable of acting.

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

            A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Thereupon the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee shall mail a notice of its
succession to Securityholders. 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.

            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.

            If the Trustee fails to comply with Section 7.10, any Securityholder
may petition any court of competent jurisdiction for the removal of the Trustee
and the appointment of a successor Trustee.

            Notwithstanding the replacement of the Trustee pursuant to this
Section, the Company's obligations under 
   93
                                                                              85


Section 7.07 shall continue for the benefit of the retiring Trustee.

            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.

            SECTION 7.10. Eligibility; Disqualification. The Trustee shall at
all times satisfy the requirements of TIA ss. 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
ss. 310(b); provided, however, that there shall be excluded from the operation
of TIA ss. 310(b)(1) any indenture or indentures under which other securities or
certificates of interest or participation in other securities of the Company are
out standing if the requirements for such exclusion set forth in TIA ss.
310(b)(1) are met.

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

   94
                                                                              86


                                  ARTICLE VIII

                       Discharge of Indenture; Defeasance

            SECTION 8.01. Discharge of Liability on Securities; Defeasance. (a)
When (i) the Company delivers to the Trustee all outstanding Securities (other
than Securities replaced pursuant to Section 2.07) 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 III hereof
and the Company irrevocably deposits with the Trustee funds or U.S. Government
Obligations on which payment of principal and interest when due will be
sufficient to pay at maturity or upon redemption all outstanding Securities,
including interest thereon to maturity or such redemption date (other than
Securities replaced pursuant to Section 2.07), and if in either case the Company
pays all other sums payable hereunder by the Company including, but not limited
to fees and expenses of the Trustee and its counsel, 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.

            (b) Subject to Sections 8.01(c), 8.02 and 8.06, the Company at any
time may terminate (i) all 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, 4.13, 4.14, 4.15,
5.01(iii) and 5.01(iv) and the operation of Sections 6.01(4), 6.01(6), 6.01(7)
(with respect to Restricted Subsidiaries only), 6.01(8) (with respect to
Restricted Subsidiaries only), 6.01(9) and 6.01(10) ("covenant defeasance
option"). The Company may exercise its legal defeasance option notwithstanding
its prior exercise of its covenant defeasance option.

            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 Sections 6.01(4),
6.01(6), 6.01(7) (with respect to Restricted Subsidiaries only), 6.01(8) (with
respect to Restricted Subsidiaries only), 6.01(9) and 6.01(10) or because of the
failure of the Company to comply with Sections 5.01(iii) and 5.01(iv).

   95
                                                                              87


            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, 7.07, 7.08, 8.04, 8.05 and
8.06 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. Conditions to Defeasance. The Company may exercise its
legal defeasance option or its covenant defeasance option only if:

            (1) the Company irrevocably deposits in trust with the Trustee money
      or U.S. Government Obligations for the payment of principal, premium (if
      any) and interest on the Securities to maturity or redemption, as the case
      may be;

            (2) 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;

            (3) 123 days pass after the deposit is made and during the 123-day
      period no Default specified in Section 6.01(7) or 6.01(8) with respect to
      the Company occurs which is continuing at the end of the period;

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

            (5) the Company delivers to the Trustee an Opinion of Counsel 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;

            (6) in the case of the legal defeasance option, the Company shall
      have delivered to the Trustee an 
   96
                                                                              88


      Opinion of Counsel stating that (i) the Company has received from, or
      there has been published by, the Internal Revenue Service a ruling, or
      (ii) 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
      Securityholders 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;

            (7) in the case of the covenant defeasance option, the Company shall
      have delivered to the Trustee an Opinion of Counsel to the effect that the
      Securityholders 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

            (8) 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
      VIII have been complied with.

            The Company shall pay and indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against the U.S. Government Obligations
deposited pursuant to this Section 8.02 or the principal, premium, if any, and
interest received in respect thereof other than any such tax, fee or other
charge which by law is for the account of the Holders of the outstanding
Securities.

            Anything in this Section 8.02 to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon the request,
in writing, by the Company any cash in dollars or U.S. Government Obligations
held by it as provided in paragraph (d) above which, in the opinion of a
nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee, are in excess of the
amount thereof which would then be required to be deposited to effect an
equivalent legal defeasance or covenant defeasance.

   97
                                                                              89


            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 III.

            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 VIII. 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.

            SECTION 8.04. Repayment to Company. The Trustee and the Paying Agent
shall promptly turn over to the Company upon request any excess money or
securities held by them at any time.

            Subject to any applicable abandoned property law, the Trustee and
the Paying Agent shall pay to the Company upon request any money held by them
for the payment of principal or interest that remains unclaimed for two years,
and, thereafter, Securityholders entitled to the money must look to the Company
for payment as general creditors.

            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 other than
any tax, fee or other charge which by law is for the account of the
Securityholders.

            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 VIII 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 VIII 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 VIII; 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 
   98
                                                                              90


U.S. Government Obligations held by the Trustee or Paying Agent.

                                   ARTICLE IX

                                   Amendments

            SECTION 9.01. Without Consent of Holders. The Company, the Guarantor
Subsidiaries and the Trustee may amend this Indenture or the Securities without
notice to or consent of any Securityholder:

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

            (2) to comply with Section 4.15 or Article V;

            (3) 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;

            (4) to make any change in Article X or Article XII that would limit
      or terminate the benefits available to any holder of Senior Indebtedness
      (or Representative therefor) under Article X or Article XII;

            (5) to add further Guarantees with respect to the Securities or to
      release Guarantor Subsidiaries when permitted by the terms hereof, or to
      secure the Securities;

            (6) 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;

            (7) to comply with any requirements of the SEC in connection with
      qualifying this Indenture under the TIA;

            (8) to make any change that does not adversely affect the rights of
      any Securityholder; or

            (9) to provide for the issuance and authorization of the Exchange
      Securities.

   99
                                                                              91


            Notwithstanding the foregoing and Section 9.02, on the date hereof
(but after execution and delivery of this Indenture and the issuance of the
Securities and after or concurrently with consummation of the Neenah Merger),
the Neenah Corporation, the Initial Guarantors and the Trustee shall execute and
deliver the First Supplemental Indenture.

            An amendment under this Section may not make any change that
adversely affects the rights under Article X or Article XII of any holder of
Senior Indebtedness of the Company or any Guarantor Subsidiary 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 becomes effective, the Company
shall mail to Securityholders a notice briefly describing such amendment. The
failure to give such notice to all Securityholders, or any defect therein, shall
not impair or affect the validity of an amendment under this Section.

            SECTION 9.02. With Consent of Holders. The Company, the Guarantor
Subsidiaries and the Trustee may amend this Indenture or the Securities without
notice to any Securityholder but with the written consent of the Holders of at
least a majority in principal amount of the Securities. The Holders of at least
a majority in principal amount of the Securities may waive compliance by the
Company or any Guarantor Subsidiary with any provision or covenant of this
Indenture or the Securities. However, without the consent of each Securityholder
affected, an amendment or waiver may not:

            (1) reduce the amount of Securities whose Holders must consent to an
      amendment or waiver;

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

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

            (4) reduce the premium payable upon the redemption of any Security
      or change the time at which any Security may be redeemed in accordance
      with Article III;

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

   100
                                                                              92


            (6) make any change in Article X or Article XII that adversely
      affects the rights of any Securityholder under Article X or Article XII;

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

            (8) modify the Subsidiary Guarantees (except as contemplated by the
      terms thereof or of this Indenture) in any manner adverse to the Holders;
      or

            (9) make any change in Section 6.04, Section 6.07 or the third
      sentence of this Section.

            It shall not be necessary for the consent of the Holders under this
Section 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 may not make any change that
adversely affects the rights under Article X or Article XII of any holder of
Senior Indebtedness of the Company or a Guarantor Subsidiary 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 becomes effective, the Company
shall mail to Securityholders a notice briefly describing such amendment. The
failure to give such notice to all Securityholders, or any defect therein, shall
not impair or affect the validity of an amendment under this Section.

            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
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 
   101
                                                                              93


receives the notice of revocation before the date the amendment or waiver
becomes effective. After an amendment or waiver becomes effective, it shall bind
every Securityholder. An amendment or waiver becomes effective once the
consents from the Holders of the requisite percentage in principal amount of
outstanding Securities are received by the Company or the Trustee.

            The Company may, but shall not be obligated to, fix a record date
for the purpose of determining the Securityholders 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
Securityholders 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 IX 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 be entitled to 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 complies with the
provisions hereof (including Section 9.03).

            SECTION 9.07. Payment for Consent. Neither the Company nor any
Affiliate of the Company shall, directly or indirectly, pay or cause to be paid
any consideration, 
   102
                                                                              94


whether by way of interest, fee or otherwise, to any Holder for or as an
inducement to any consent, waiver or amendment of any of the terms or provisions
of this Indenture or the Securities unless such consideration is offered to be
paid to all Holders that so consent, waive or agree to amend in the time frame
set forth in solicitation documents relating to such consent, waiver or
agreement.

                                    ARTICLE X

                         Subordination of the Securities

            SECTION 10.01. Agreement To Subordinate. The Company agrees, and
each Securityholder 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 X, 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 Senior Indebtedness of the Company.
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 these
subordination provisions, the Indebtedness evidenced by the Securities is deemed
to include the liquidated damages payable pursuant to the provisions set forth
in the Securities and the Exchange and Registration Rights Agreement. All
provisions of this Article X 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 total
or partial liquidation or a total or partial dissolution of the Company or in a
bankruptcy, reorganization, insolvency, receivership or similar proceeding
relating to the Company and its properties:

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

            (2) until the Senior Indebtedness of the Company is paid in full,
      any payment or distribution to which Securityholders would be entitled but
      for this 
   103
                                                                              95


      Article X shall be made to holders of such Senior Indebtedness as their
      respective interests may appear.

            SECTION 10.03. Default on Senior Indebtedness of the Company. 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
purchase, redeem or otherwise retire any Securities (collectively, "pay the
Securities") if (i) any Senior Indebtedness of the Company is not paid when due
or (ii) any other default on Senior Indebtedness of the Company occurs and the
maturity of such Senior Indebtedness is accelerated in accordance with its terms
unless, in either case, (x) the default has been cured or waived and any such
acceleration has been rescinded or (y) such 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 the Trustee receive written notice approving
such payment from the Representative of the holders of such Senior Indebtedness
with respect to which either of the events in clause (i) or (ii) of this
sentence has occurred and is continuing. During the continuance of any default
(other than a default described in clause (i) or (ii) 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 the Trustee (with a copy to the Company) of written notice (a
"Blockage Notice") of such default from the Representative of the holders of the
Designated Senior Indebtedness of the Company specifying an election to effect a
Payment Blockage Period and ending 179 days thereafter (or earlier if such
Payment Blockage Period is terminated (i) by written notice to the Trustee (with
a copy to the Company) from the Person or Persons who gave such Blockage Notice,
(ii) because such Designated Senior Indebtedness has been repaid in full or
(iii) 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 first
sentence of this Section), unless the holders of such Designated Senior
Indebtedness or the Representative of such holders shall have accelerated the
maturity of such Designated Senior Indebtedness, the Company may resume payments
on the Securities after such Payment Blockage Period, including any missed
payments. Not more than one Blockage Notice may be given in any consecutive
360-day 
   104
                                                                              96


period, irrespective of the number of defaults with respect to Designated Senior
Indebtedness of the Company 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 of the Company (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.

            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 shall promptly notify the holders of the Designated Senior Indebtedness
of the Company (or the Representative of such holders) 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 the holders of the Designated Senior Indebtedness of the
Company receive notice of such acceleration and, thereafter, may pay the
Securities only if this Article X otherwise permits payment at that time.

            SECTION 10.05. When Distribution Must Be Paid Over. If a payment or
distribution is made to Securityholders that because of this Article X should
not have been made to them, the Securityholders who receive the payment or
distribution shall hold such payment or distribution in trust for holders of the
Senior Indebtedness of the Company and pay it over to them as their respective
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,
Securityholders shall be subrogated to the rights of holders of Senior
Indebtedness of the Company to receive distributions applicable to Senior
Indebtedness of the Company. A distribution made under this Article X to holders
of Senior Indebtedness of the Company which otherwise would have been made to
Securityholders is not, as between the Company and Securityholders, a payment by
the Company on Senior Indebtedness of the Company.

   105
                                                                              97


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

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

            (2) prevent the Trustee or any Securityholder 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 Securityholders.

            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 Trust Officer of the Trustee
receives written notice satisfactory to it that payments may not be made under
this Article X. The Company, the Registrar or co-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 shall be entitled to rely on the delivery to it of a written notice by a
Person representing himself or itself to be a holder of any Senior Indebtedness
of the Company (or a Representative of such holder) to establish that such
notice has been given by a holder of such Senior Indebtedness or Representative
thereof.

            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 co-registrar and the Paying Agent may do the same
with like rights. The Trustee shall be entitled to all 
   106
                                                                              98


the rights set forth in this Article X 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 Senior Indebtedness of the Company; and nothing in Article VII
shall deprive the Trustee of any of its rights as such holder. Nothing in this
Article X shall apply to claims of, or payments to, the Trustee under or
pursuant to Section 7.07.

            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 X 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 X shall not be construed as preventing
the occurrence of a Default. Nothing in this Article X shall have any effect on
the right of the Securityholders or the Trustee to accelerate the maturity of
the Securities.

            SECTION 10.12. Trust Moneys 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 VIII by the Trustee
for the payment of principal of and interest on the Securities 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 X, and none of the
Securityholders 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 X, the Trustee and the Securityholders
shall be entitled to rely (i) 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, (ii) upon a certificate of the liquidating trustee or agent or
other Person making such payment or distribution to the Trustee or to the
Securityholders or (iii) 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 the Senior
Indebtedness of the Company and other Indebtedness of the Company, the amount
thereof or payable thereon, the amount 
   107
                                                                              99


or amounts paid or distributed thereon and all other facts pertinent thereto or
to this Article X. 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 X, the Trustee may request such Person to furnish
evidence to the reasonable satisfaction of the Trustee as to the amount of
Senior Indebtedness of the Company 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 X, 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 X.

            SECTION 10.14. Trustee To Effectuate Subordination. Each
Securityholder 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 Securityholders and the holders of
Senior Indebtedness of the Company as provided in this Article X 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 of the Company. 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 Securityholders 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 X or otherwise.

            SECTION 10.16. Reliance by Holders of Senior Indebtedness of the
Company on Subordination Provisions. Each Securityholder 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 of the Company shall be deemed conclusively to have
relied on 
   108
                                                                             100


such subordination provisions in acquiring and continuing to hold, or in
continuing to hold, such Senior Indebtedness.

            SECTION 10.17. Trustee's Compensation Not Prejudiced. Nothing in
this Article shall apply to amounts due to the Trustee pursuant to other
sections of this Indenture.

                                   ARTICLE XI

                              Subsidiary Guarantees

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

            Each Guarantor Subsidiary waives presentation to, demand of, payment
from and protest to the Company of any of the Obligations and also waives notice
of protest for nonpayment. Each Guarantor Subsidiary waives notice of any
default under the Securities or the Obligations. The obligations of each
Guarantor Subsidiary hereunder shall not be affected by (a) 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; (b) any extension or renewal of
any thereof; (c) any rescission, waiver, amendment or modification of any of the
terms or provisions of this Indenture, the Securities or any other agreement;
(d) the release of any security held by any Holder or the Trustee for the
Obligations or any of 
   109
                                                                             101


them; (e) the failure of any Holder or Trustee to exercise any right or remedy
against any other guarantor of the Obligations; or (f) any change in the
ownership of such Guarantor Subsidiary, except as provided in Section 11.02(b).

            Each Guarantor Subsidiary further agrees that its Subsidiary
Guaranty 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 Obligations.

            The obligations of each Guarantor Subsidiary 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 Obligations or otherwise. Without limiting the
generality of the foregoing, the obligations of each Guarantor Subsidiary 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, willful 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 Guarantor Subsidiary or would
otherwise operate as a discharge of any Guarantor Subsidiary as a matter of law
or equity.

            Each Guarantor Subsidiary further agrees that its Subsidiary
Guaranty 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 Obligation is rescinded or must otherwise be restored by any Holder or the
Trustee upon the bankruptcy or reorganization of the Company or otherwise.

            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
Guarantor Subsidiary by virtue hereof, upon the failure of the Company to pay
the principal of or interest on any Obligation when and as the same shall become
due, whether at maturity, by acceleration, by redemption or otherwise, or to
perform or 
   110
                                                                             102


comply with any other Obligation, each Guarantor Subsidiary 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 Obligations, (ii) accrued and
unpaid interest on such 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.

            Each Guarantor Subsidiary agrees that it shall not be entitled to
any right of subrogation in relation to the Holders in respect of any
Obligations guaranteed hereby until payment in full of all Obligations. Each
Guarantor Subsidiary further agrees that, as between it, on the one hand, and
the Holders and the Trustee, on the other hand, (x) the maturity of the
Obligations guaranteed hereby may be accelerated as provided in Article VI for
the purposes of any Subsidiary Guaranty herein, notwithstanding any stay,
injunction or other prohibition preventing such acceleration in respect of the
Obligations guaranteed hereby, and (y) in the event of any declaration of
acceleration of such Obligations as provided in Article VI, such Obligations
(whether or not due and payable) shall forthwith become due and payable by such
Guarantor Subsidiary for the purposes of this Section.

            Each Guarantor Subsidiary also agrees to pay any and all costs and
expenses (including reasonable attorneys' fees and expenses) incurred by the
Trustee or any Holder in enforcing any rights under this Section.

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

            (b) This Subsidiary Guaranty as to any Guarantor Subsidiary shall
terminate and be of no further force or effect upon the sale or other transfer
(i) by such Guarantor Subsidiary of all or substantially all of its assets or
(ii) by the Company of all of its stock or other equity interests in such
Guarantor Subsidiary, to a Person that is not an Affiliate of the Company;
provided, however, that such sale or transfer shall be deemed to constitute an
Asset 
   111
                                                                             103


Disposition and the Company shall comply with its obligations under Section
4.06.

            SECTION 11.03. Successors and Assigns. This Article XI shall be
binding upon each Guarantor Subsidiary and its successors and assigns and shall
enure 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.

            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 XI 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 XI at law,
in equity, by statute or otherwise.

            SECTION 11.05. Modification. No modification, amendment or waiver of
any provision of this Article XI, nor the consent to any departure by any
Guarantor Subsidiary 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 Guarantor Subsidiary in any case shall
entitle such Guarantor Subsidiary to any other or further notice or demand in
the same, similar or other circumstances.

            SECTION 11.06. Initial Guarantors; Execution of Supplemental
Indenture for Future Guarantor Subsidiaries. (a) Upon consummation of the Neenah
Merger and execution and delivery of the First Supplemental Indenture pursuant
to Section 9.01 hereof, the Initial Guarantors will become Guarantor
Subsidiaries.

            (b) Each Subsidiary which is required to become a Guarantor
Subsidiary pursuant to Section 4.15 shall promptly execute and deliver to the
Trustee a supplemental indenture in the form of Exhibit D hereto pursuant to
which such Subsidiary shall become a Guarantor Subsidiary under this 
   112
                                                                             104


Article XI and shall guarantee the 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 Subsidiary Guaranty of such Guarantor
Subsidiary is a legal, valid and binding obligation of such Guarantor
Subsidiary, enforceable against such Guarantor Subsidiary in accordance with its
terms.

                                   ARTICLE XII

                   Subordination of the Subsidiary Guaranties

            SECTION 12.01. Agreement To Subordinate. Each Guarantor Subsidiary
agrees, and each Securityholder by accepting a Security agrees, that the
Obligations of a Guarantor Subsidiary are subordinated in right of payment, to
the extent and in the manner provided in this Article XII, to the prior payment
in full of all Senior Indebtedness of such Guarantor Subsidiary and that the
subordination is for the benefit of and enforceable by the holders of Senior
Indebtedness of such Guarantor Subsidiary. The Obligations with respect to a
Guarantor Subsidiary shall in all respects rank pari passu with all other Senior
Subordinated Indebtedness of such Guarantor Subsidiary, and only Indebtedness of
such Guarantor Subsidiary that is Senior Indebtedness of such Guarantor
Subsidiary shall rank senior to the Obligations of such Guarantor Subsidiary in
accordance with the provisions set forth herein.

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

            (1) holders of Senior Indebtedness of such Guarantor Subsidiary
      shall be entitled to receive payment in full of such Senior Indebtedness
      before Securityholders shall be entitled to receive any payment of any
      Obligations from such Guarantor Subsidiary; and

   113
                                                                             105


            (2) until the Senior Indebtedness of such Guarantor Subsidiary is
      paid in full, any payment or distribution to which Securityholders would
      be entitled but for this Article XII shall be made to holders of such
      Senior Indebtedness as their respective interests may appear.

            SECTION 12.03. Default on Senior Indebtedness of a Guarantor
Subsidiary. A Guarantor Subsidiary may not make any payment pursuant to any of
the Obligations or repurchase, redeem or otherwise retire any Securities
(collectively, "pay its Guaranty") if (i) any Senior Indebtedness of such
Guarantor Subsidiary is not paid when due or (ii) any other default on Senior
Indebtedness of such Guarantor Subsidiary occurs and the maturity of such Senior
Indebtedness is accelerated in accordance with its terms unless, in either case,
(x) the default has been cured or waived and any such acceleration has been
rescinded or (y) such Senior Indebtedness has been paid in full; provided,
however, that such Guarantor Subsidiary may pay its Guaranty without regard to
the foregoing if such Guarantor Subsidiary and the Trustee receive written
notice approving such payment from the Representative of the holders of such
Senior Indebtedness with respect to which either of the events in clause (i) or
(ii) of this sentence has occurred and is continuing. During the continuance of
any default (other than a default described in clause (i) or (ii) of the
preceding sentence) with respect to any Designated Senior Indebtedness of a
Guarantor Subsidiary 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 Subsidiary Guarantor may not pay its Guaranty for a period (a "Guarantor
Subsidiary Payment Blockage Period") commencing upon the receipt by the Trustee
(with a copy to such Guarantor Subsidiary and the Company) of written notice (a
"Guarantor Subsidiary Blockage Notice") of such default from the Representative
of the holders of the Designated Senior Indebtedness of such Guarantor
Subsidiary specifying an election to effect a Guarantor Subsidiary Payment
Blockage Period and ending 179 days thereafter (or earlier if such Guarantor
Subsidiary Payment Blockage Period is terminated (i) by written notice to the
Trustee (with a copy to such Guarantor Subsidiary and the Company) from the
Person or Persons who gave such Guarantor Subsidiary Blockage Notice, (ii)
because such Designated Senior Indebtedness has been repaid in full or (iii)
because the default giving rise to such Guarantor Subsidiary Blockage Notice is
no longer continuing). Notwithstanding the provisions described in 
   114
                                                                             106


the immediately preceding sentence (but subject to the provisions contained in
the first sentence of this Section), 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 Guarantor Subsidiary
may resume to pay its Guaranty after such Guarantor Subsidiary Payment Blockage
Period, including any missed payments. Not more than one Guarantor Subsidiary
Blockage Notice may be given with respect to a Guarantor Subsidiary in any
consecutive 360-day period, irrespective of the number of defaults with respect
to Designated Senior Indebtedness of such Guarantor Subsidiary during such
period; provided, however, that if any Guarantor Subsidiary Blockage Notice
within such 360-day period is given by or on behalf of any holders of Designated
Senior Indebtedness of such Guarantor Subsidiary (other than the Bank
Indebtedness), the Representative of the Bank Indebtedness may give another
Guarantor Subsidiary Blockage Notice within such period; provided further,
however, that in no event may the total number of days during which any
Guarantor Subsidiary Payment Blockage Period or Periods is in effect exceed 179
days in the aggregate during any 360 consecutive day period.

            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
Guarantor Subsidiary pursuant to Article XI the Trustee shall promptly notify
the holders of the Designated Senior Indebtedness of such Guarantor Subsidiary
(or the Representative of such holders) of such demand. If any Designated Senior
Indebtedness of such Guarantor Subsidiary is outstanding, such Guarantor
Subsidiary may not pay its Guaranty until five Business Days after such holders
or the Representative of the holders of the Designated Senior Indebtedness of
such Guarantor Subsidiary receive notice of such demand and, thereafter, may pay
its Guaranty only if this Article XII otherwise permits payment at that time.

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

            SECTION 12.06. Subrogation. After all Senior Indebtedness of a
Guarantor Subsidiary is paid in full and 
   115
                                                                             107


until the Securities are paid in full, Securityholders shall be subrogated to
the rights of holders of Senior Indebtedness of such Guarantor Subsidiary to
receive distributions applicable to Senior Indebtedness of such Guarantor
Subsidiary. A distribution made under this Article XII to holders of Senior
Indebtedness of such Guarantor Subsidiary which otherwise would have been made
to Securityholders is not, as between such Guarantor Subsidiary and
Securityholders, a payment by such Guarantor Subsidiary on Senior Indebtedness
of such Guarantor Subsidiary.

            SECTION 12.07. Relative Rights. This Article XII defines the
relative rights of Securityholders and holders of Senior Indebtedness of a
Guarantor Subsidiary. Nothing in this Indenture shall:

            (1) impair, as between a Guarantor Subsidiary and Securityholders,
      the obligation of a Guarantor Subsidiary which is absolute and
      unconditional, to pay its Obligations to the extent set forth in Article
      XI; or

            (2) prevent the Trustee or any Securityholder from exercising its
      available remedies upon a default by a Guarantor Subsidiary under its
      Obligations, subject to the rights of holders of Senior Indebtedness of
      such Guarantor Subsidiary to receive distributions otherwise payable to
      Securityholders.

            SECTION 12.08. Subordination May Not Be Impaired by a Guarantor
Subsidiary. No right of any holder of Senior Indebtedness of a Guarantor
Subsidiary to enforce the subordination of the Obligations of such Guarantor
Subsidiary shall be impaired by any act or failure to act by such Guarantor
Subsidiary 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 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 Trust Officer of the Trustee
receives notice satisfactory to it that payments may not be made under this
Article XII. A Guarantor Subsidiary, the Registrar or co-registrar, the Paying
Agent, a Representative or a holder of Senior Indebtedness of a Guarantor
Subsidiary may give the notice; provided, however, that, if an issue of Senior
Indebtedness of a Guarantor Subsidiary has a Representative, 
   116
                                                                             108


only the Representative may give the notice. The Trustee shall be entitled to
rely on the delivery to it of a written notice by a Person representing himself
or itself to be a holder of any Senior Indebtedness of a Guarantor Subsidiary
(or a Representative of such holder) to establish that such notice has been
given by a holder of such Senior Indebtedness or Representative thereof.

            The Trustee in its individual or any other capacity may hold Senior
Indebtedness of a Guarantor Subsidiary 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 XII with respect to any Senior Indebtedness of a Guarantor
Subsidiary which may at any time be held by it, to the same extent as any other
holder of Senior Indebtedness of such Guarantor Subsidiary; and nothing in
Article VII shall deprive the Trustee of any of its rights as such holder.
Nothing in this Article XII shall apply to claims of, or payments to, the
Trustee under or pursuant to Section 7.07.

            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 Guarantor Subsidiary, the distribution may be made and the notice given to
their Representative (if any).

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

            SECTION 12.12. Trustee Entitled To Rely. Upon any payment or
distribution pursuant to this Article XII, the Trustee and the Securityholders
shall be entitled to rely (i) 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, (ii) upon a certificate of the liquidating trustee or agent or
other Person making such payment or distribution to the Trustee or to the
Securityholders or (iii) upon the Representatives for the holders of Senior
Indebtedness of a Guarantor Subsidiary for the purpose of ascertaining the
Persons entitled to participate 
   117
                                                                             109


in such payment or distribution, the holders of the Senior Indebtedness of a
Guarantor Subsidiary and other Indebtedness of a Guarantor Subsidiary, the
amount thereof or payable thereon, the amount or amounts paid or distributed
thereon and all other facts pertinent thereto or to this Article XII. 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
Guarantor Subsidiary to participate in any payment or distribution pursuant to
this Article XII, 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 Guarantor Subsidiary 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 XII, 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 XII.

            SECTION 12.13. Trustee To Effectuate Subordination. Each
Securityholder 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 Securityholders and the holders of
Senior Indebtedness of each of the Guarantor Subsidiaries as provided in this
Article XII 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 Guarantor Subsidiary. The Trustee shall not be deemed to owe
any fiduciary duty to the holders of Senior Indebtedness of a Guarantor
Subsidiary and shall not be liable to any such holders if it shall mistakenly
pay over or distribute to Securityholders or the relevant Guarantor Subsidiary
or any other Person, money or assets to which any holders of Senior Indebtedness
of such Guarantor Subsidiary shall be entitled by virtue of this Article XII or
otherwise.

            SECTION 12.15. Reliance by Holders of Senior Indebtedness of a
Guarantor Subsidiary on Subordination Provisions. Each Securityholder 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 
   118
                                                                             110


Guarantor Subsidiary, 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.

                                  ARTICLE XIII

                                  Miscellaneous

            SECTION 13.01. Trust Indenture Act Controls. If any provision of
this Indenture limits, qualifies or conflicts with another provision which is
required to be included in this Indenture by the TIA, the required provision
shall control.

            SECTION 13.02. Notices. Any notice or communication shall be in
writing and delivered in person or mailed by first-class mail or by national
overnight courier service addressed as follows:

      if to the Company or any Guarantor Subsidiary:

                               2121 Brooks Avenue
                                Neenah, WI 54957

                               if to the Trustee:

                        114 West 47th Street, 25th Floor
                            New York, New York 10036
                       Attention: Corporate Trust Division

            The Company or the Trustee by notice to the other may designate
additional or different addresses for subsequent notices or communications.

            Any notice or communication mailed to a Securityholder shall be
mailed to the Securityholder at the Securityholder's address as it appears on
the registration books of the Registrar and shall be sufficiently given if so
mailed by first class mail within the time prescribed.

            Failure to mail a notice or communication to a Securityholder or any
defect in it shall not affect its 
   119
                                                                             111


sufficiency with respect to other Securityholders. If a notice or communication
is mailed in the manner provided above, it is duly given, whether or not the
addressee receives it, except that any such notice to the Trustee must be
received by a Trust Officer to be duly given.

            Where this Indenture provides for notice in any manner, such notice
may be waived in writing by the Person entitled to receive such notice, either
before or after the event, and such waiver shall be the equivalent of such
notice.

            SECTION 13.03. Communication by Holders with Other Holders.
Securityholders may communicate pursuant to TIA ss. 312(b) with other
Securityholders with respect to their rights under this Indenture or the
Securities. The Company, the Trustee, the Registrar and anyone else shall have
the protection of TIA ss. 312(c).

            SECTION 13.04. Certificate and Opinion as to Conditions Precedent.

      complied with.

            SECTION 13.05. Statements Required in Certificate or Opinion. Each

direction, waiver or consent, Securities owned by the Company or by any Person
directly or indirectly controlling or controlled by or under direct or indirect
common control with the Company shall be disregarded and deemed not to be
outstanding, except that, for the purpose of determining whether the Trustee
shall be protected in relying on any such direction, waiver or consent, only
Securities which the Trustee knows are so owned shall be so disregarded. Also,
subject to the foregoing, only Securities outstanding at the time shall be
considered in any such determination.

Securities.

                    11-1/8% Senior Subordinated Note due 2007

1. Interest

            NC Merger Company, a Wisconsin 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 and the
Guarantor Subsidiaries will use their best efforts to have the Exchange Offer
Registration Statement or, if applicable, the Shelf Registration Statement (each
a "Registration Statement") declared effective by the Commission as promptly as
practicable after the filing thereof. If (i) the Shelf Registration Statement or
Exchange Offer Registration Statement, as applicable under the Exchange and
Registration Rights Agreement is not filed with the Commission on or prior to 45
days after the Issue Date, (ii) the Exchange Offer Registration Statement or, as
the case may be, the Shelf Registration Statement, is not declared effective
within 105 days after the Issue Date, (iii) the Exchange Offer is not
consummated on or prior to 135 days after the Issue Date, or (iv) the Shelf
Registration Statement is filed and declared effective within 105 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 30 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 will 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
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
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 will cease. The Trustee shall have no responsibility with respect to the
determination of the 
   128
                                                                               6


amount of any such liquidated damages. For purposes of the foregoing, "Transfer
Restricted Securities" means each Initial Security until (i) the date on which
such Initial Security has been exchanged for a freely transferable Exchange
Security in the Exchange Offer, (ii) the date on which such Initial Security has
been effectively registered under the Securities Act and disposed of in
accordance with the Shelf Registration Statement or (iii) the date on which such
Initial 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.

            The Company will pay interest and liquidated damages, if any,
semiannually on May 1 and November 1 of each year. Interest on the Securities
will accrue from the most recent date to which interest has been paid or, if no
interest has been paid, from April 30, 1997. Interest will be computed on the
basis of a 360-day year of twelve 30-day months. The Company shall pay interest
on overdue principal at the rate borne by the 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 will pay interest (except defaulted interest) on and
liquidated damages, if any, in respect of the Securities to the Persons who are
registered holders of Securities at the close of business on the April 15 or
October 15 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 will pay principal and interest in money of the United
States that at the time of payment is legal tender for payment of public and
private debts. However, the Company may pay principal and interest by check
payable in such money or by wire transfer of federal funds.

   129
                                                                               7


3. Paying Agent and Registrar

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

4. Indenture and First Supplemental Indenture

            The Company issued the Securities under an Indenture dated as of
April 30, 1997 ("Indenture"), between the Company 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. ss.ss.
77aaa-77bbbb) as in effect on the date of the Indenture (the "Act"). Terms
defined in the Indenture and not defined herein have the meanings ascribed
thereto in the Indenture. The Securities are subject to all such terms, and
Securityholders are referred to the Indenture and the Act for a statement of
those terms.

            Pursuant to the First Supplemental Indenture dated as of April 30,
1997, among Neenah Corporation, the Initial Guarantors and the Trustee, Neenah
Corporation assumed the Company's obligations under the Indenture and the
Securities and each of the Initial Guarantors agreed to guarantee those
obligations under the Indenture and the Securities.

            The Securities are unsecured senior subordinated 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 Securities referred to in the Indenture. The Securities include the
Initial Securities and any Exchange Securities issued in exchange for the
Initial Securities pursuant to the Indenture. The Initial Securities and the
Exchange Securities are treated as a single class of securities under the
Indenture. The Indenture imposes certain limitations on the Incurrence of
Indebtedness by the Company and its Restricted Subsidiaries; the payment of
dividends on, and redemption of, Capital Stock of the Company and its Restricted
Subsidiaries and the redemption of certain Subordinated Obligations of the
Company and its Restricted Subsidiaries; Investments; sales of assets and

   130
                                                                               8


Restricted Subsidiary Capital Stock; certain transactions with Affiliates of the
Company; the sale or issuance of Capital Stock of the Restricted Subsidiaries;
the creation of Liens; the lines of business in which the Company and its
Restricted Subsidiaries may operate; Sale/Leaseback Transactions and
consolidations, mergers and transfers of all or substantially all of the
Company's assets. In addition, the Indenture prohibits certain restrictions on
distributions and dividends from Restricted Subsidiaries.

            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 (as supplemented by the First
Supplemental Indenture), the Initial Guarantors have guaranteed the Company's
obligations under the Indenture on a senior subordinated basis pursuant to the
terms of the Indenture.

5. Optional Redemption

            Except as set forth in the next two paragraphs, the Securities may
not be redeemed prior to May 1, 2002. On and after that date, the Company may
redeem the Securities in whole at any time or in part from time to time at the
following redemption prices (expressed in percentages of principal amount), plus
accrued and unpaid interest, 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 that is on or prior to the date of
redemption), if redeemed during the 12-month period beginning on or after May 1
of the years set forth below:

interest, 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 at least 60% of the original
aggregate principal amount of the Securities must remain outstanding after each
such redemption.

            At any time prior to May 1, 2002, the Securities may be redeemed, in
whole or in part, at the option of the Company within 180 days after a Change of
Control, at a redemption price equal to the sum of (i) the principal amount
thereof plus (ii) accrued and unpaid interest, 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 that is on or prior
to the date of redemption) plus (iii) the Applicable Premium.

6. 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 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 interest
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.

7. Put Provisions

            Upon a Change of Control, unless the Company has elected to redeem
the Securities pursuant to paragraph 5, 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 
   132
                                                                              10


accrued and unpaid interest, if any, to the date of purchase (subject to the
right of Holders of record on the relevant record date to receive interest 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.

8. Subordination

            The Securities are subordinated to Senior Indebtedness of the
Company, as defined in the Indenture. To the extent provided in the Indenture,
Senior Indebtedness of the Company must be paid before the Securities may be
paid. In addition, each Subsidiary Guaranty is subordinated to Senior
Indebtedness of the relevant Guarantor Subsidiary, as defined in the Indenture.
The Company and each Guarantor Subsidiary agrees, and each Securityholder 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.

9. 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.

10. Persons Deemed Owners

            The registered Holder of this Security may be treated as the owner
of it for all purposes.

   133
                                                                              11


11. 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.

12. Discharge and Defeasance

            Subject to certain conditions, the Company at any time may terminate
some or all of 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.

13. Amendment, Waiver

            Subject to certain exceptions set forth in the Indenture, (i) the
Indenture or the Securities may be amended with the written consent of the
Holders of at least a majority in principal amount outstanding of the Securities
and (ii) any past default or noncompliance with any provision may be waived
with the consent of the Holders of a majority in principal amount then
outstanding of the Securities. Subject to certain exceptions set forth in the
Indenture, without the consent of any Securityholder, the Company and the
Trustee may amend the Indenture or the Securities to cure any ambiguity,
omission, defect or inconsistency, or to comply with Article V of the Indenture,
or to provide for uncertificated Securities in addition to or in place of
certificated Securities, or to add guarantees with respect to the Securities or
to secure the Securities, or to release Guarantor Subsidiaries when permitted by
the Indenture, or to add additional covenants or surrender rights and powers
conferred on the Company, or to comply with any request of the SEC in connection
with qualifying the Indenture under the Act, or to make any other change that
does not adversely affect the rights of any Securityholder, or to provide for
the issuance and authorization of the Exchange Securities.

   134
                                                                              12


14. Defaults and Remedies

            Under the Indenture, Events of Default include (i) default for 30
days in payment of interest on the Securities; (ii) default in payment of
principal on the Securities at maturity, upon redemption pursuant to paragraph
5 of the Securities, or failure by the Company to redeem or purchase, upon
declaration or otherwise (whether or not such payment is prohibited by Article
X), Securities when required; (iii) failure by the Company or any Guarantor
Subsidiary to comply with other agreements in the Indenture or the Securities,
in certain cases subject to notice and lapse of time; (iv) certain accelerations
(including failure to pay within any grace period after final maturity) of other
Indebtedness of the Company or a Significant Subsidiary if the amount
accelerated (or so unpaid) exceeds $5,000,000 or its foreign currency
equivalent; (v) certain events of bankruptcy, insolvency or reorganization with
respect to the Company and its Restricted Subsidiaries; (vi) certain judgments
or decrees not covered by insurance for the payment of money in excess of
$5,000,000 or its foreign currency equivalent against the Company or a
Restricted Subsidiary; and (vii) a Subsidiary Guaranty ceasing to be in full
force and effect (other than in accordance with its terms) or any Guarantor
Subsidiary denies or disaffirms its obligations under the Indenture or any
Subsidiary Guaranty and such Default continues for 10 days. If an Event of
Default occurs and is continuing, the Trustee or the Holders of at least 25% in
principal amount of the Securities may declare all the Securities to be due and
payable immediately. Certain events of bankruptcy or insolvency are Events of
Default which will result in the Securities being due and payable immediately
upon the occurrence of such Events of Default.

            Securityholders may not enforce the Indenture or the Securities
except as provided in the Indenture. The Trustee may refuse to enforce the
Indenture or the Securities unless it receives reasonable indemnity or
security. Subject to certain limitations, Holders of a majority in principal
amount of the Securities may direct the Trustee in its exercise of any trust or
power. The Trustee may withhold from Securityholders notice of any continuing
Default (except a Default in payment of principal, premium, if any, or interest)
if and so long as a committee of its Trust Officers in good faith determines
that withholding notice is in the interest of the Holders.

   135
                                                                              13


15. Trustee Dealings with the Company

            Subject to certain limitations imposed by the Act, the Trustee under
the Indenture, in its individual or any other capacity, may become the owner or
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.

16. No Recourse Against Others

            A director, officer, employee or stockholder, as such, of the
Company or any Guarantor Subsidiary shall not have any liability for any
obligations of the Company or a Guarantor Subsidiary 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 Securityholder
waives and releases all such liability. The waiver and release are part of the
consideration for the issue of the Securities.

17. Governing Law

            THE SECURITIES 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.

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 Securityholder
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).

20. CUSIP Numbers

            Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures the Company has caused CUSIP numbers to be
printed on the Securities and has directed the Trustee to use CUSIP numbers in
notices of redemption as a convenience to Securityholders. 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 Securityholder upon written request
and without charge to the Securityholder a copy of the Indenture which has in
it the text of this Security in larger type. Requests may be made to:

               11-1/8% Series B Senior Subordinated Note due 2007

1. Interest

            NEENAH CORPORATION, a Wisconsin 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 will pay
interest and liquidated damages, if any, semiannually on May 1 and November 1 of
each year. Interest on the Securities will accrue from the most recent date to
which interest has been paid or, if no interest has been paid, from April 30,
1997. Interest will be computed on the basis of a 360-day year of twelve 30-day
months. The Company shall pay interest on overdue principal at the rate borne by
the 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 will pay interest on the Securities (except defaulted
interest) to the Persons who are registered holders of Securities at the close
of business on the April 15 or October 15 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 will pay principal and interest in money
of the United States that at the time of payment is legal tender for payment of
public and private debts. However, the Company may pay principal and interest by
check payable in such money or by wire transfer of federal funds.

3. Paying Agent and Registrar

            Initially, UNITED STATES TRUST COMPANY OF NEW YORK, a New York
banking corporation ("Trustee"), will act as Paying Agent and Registrar. The
Company may appoint and change any Paying Agent, Registrar or co-registrar
without notice to the Holders. The Company or any of its domestically
incorporated

   146
                                                                               4


Wholly Owned Subsidiaries may act as Paying Agent, Registrar or co-registrar.

4. Indenture; First Supplemental Indenture

            NC Merger Company, a Wisconsin corporation ("NC Merger"), issued the
Securities under an Indenture dated as of April 30, 1997 ("Indenture"), among NC
Merger 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. ss.ss. 77aaa-77bbbb) as in effect on the date
of the Indenture (the "Act"). Terms defined in the Indenture and not defined
herein have the meanings ascribed thereto in the Indenture. The Securities are
subject to all such terms, and Securityholders are referred to the Indenture and
the Act for a statement of those terms.

            Pursuant to the First Supplemental Indenture dated as of April 30,
1997, among the Company, the Initial Guarantors and the Trustee, the Company
assumed NC Merger's obligations under the Indenture and the Securities and each
of the Initial Guarantors agreed to guarantee those obligations under the
Indenture and the Securities.

            The Securities are unsecured senior subordinated 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 Exchange Securities referred to in the Indenture. The Securities include the
Initial Securities and any Exchange Securities issued in exchange for the
Initial Securities pursuant to the Indenture. The Initial Securities and the
Exchange Securities are treated as a single class of securities under the
Indenture. The Indenture imposes certain limitations on the Incurrence of
Indebtedness by the Company and its Restricted Subsidiaries; the payment of
dividends on, and redemption of, Capital Stock of the Company and its Restricted
Subsidiaries and the redemption of certain Subordinated Obligations of the
Company and its Restricted Subsidiaries; Investments; sales of assets and
Restricted Subsidiary Capital Stock; certain transactions with Affiliates of the
Company; the sale or issuance of Capital Stock of the Restricted Subsidiaries;
the creation of Liens; the lines of business in which the Company and its
Restricted Subsidiaries may operate; Sale/Leaseback Transactions and
consolidations, mergers and transfers of all or substantially all of the
Company's assets. In addition, the Indenture prohibits certain

   147
                                                                               5


restrictions on distributions and dividends from Restricted Subsidiaries.

            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 Guarantor Subsidiaries have
guaranteed the Company's obligations under the Indenture on a senior
subordinated basis pursuant to the terms of the Indenture.

5. Optional Redemption

            Except as set forth in the next two paragraphs, the Securities may
not be redeemed prior to May 1, 2002. On and after that date, the Company may
redeem the Securities in whole at any time or in part from time to time at the
following redemption prices (expressed in percentages of principal amount), plus
accrued and unpaid interest, 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 that is on or prior to the date of
redemption), if redeemed during the 12-month period beginning on or after May 1
of the years set forth below:

                                                                  Redemption 
Period                                                              Price    
- ------                                                            ---------- 
                                                                             
2002............................................................   105.5625%

2000, the Company may redeem in the aggregate up to 40% of the original
aggregate principal amount of Securities with the proceeds of one or more Public
Equity Offerings at a redemption price (expressed as a percentage of principal
amount thereof) of 111.125% plus accrued and unpaid interest, 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 that
is on or prior to the date of redemption); provided, however, that at least 60%
of the original

   148
                                                                               6


aggregate principal amount of the Securities must remain outstanding after each
such redemption.

            At any time prior to May 1, 2002, the Securities may be redeemed, in
whole or in part, at the option of the Company within 180 days after a Change of
Control, at a redemption price equal to the sum of (i) the principal amount
thereof plus (ii) accrued and unpaid interest, 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 that is on or prior
to the date of redemption) plus (iii) the Applicable Premium.

6. 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 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 interest
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.

7. Put Provisions

            Upon a Change of Control, unless the Company has elected to redeem
the Securities pursuant to paragraph 5, any Holder of Securities will have the
right, subject to certain conditions specified in the Indenture, to cause the
Company to purchase all or any part of the Securities of such Holder at a
repurchase price equal to 101% of the principal amount of the Securities to be
repurchased plus accrued and unpaid interest, if any, to the date of purchase
(subject to the right of Holders of record on the relevant record date to
receive interest 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.

   149
                                                                               7


8. Subordination

            The Securities are subordinated to Senior Indebtedness of the
Company, as defined in the Indenture. To the extent provided in the Indenture,
Senior Indebtedness of the Company must be paid before the Securities may be
paid. In addition, each Subsidiary Guaranty is subordinated to Senior
Indebtedness of the relevant Guarantor Subsidiary, as defined in the Indenture.
The Company and each Guarantor Subsidiary agrees, and each Securityholder 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.

9. 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 Regis trar 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.

10. Persons Deemed Owners

            The registered Holder of this Security may be treated as the owner
of it for all purposes.

11. 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.

   150
                                                                               8


12. Discharge and Defeasance

            Subject to certain conditions, the Company at any time may terminate
some or all of 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.

13. Amendment, Waiver

            Subject to certain exceptions set forth in the Indenture, (i) the
Indenture or the Securities may be amended with the written consent of the
Holders of at least a majority in principal amount outstanding of the Securities
and (ii) any past default or noncompliance with any provision may be waived with
the consent of the Holders of a majority in principal amount then outstanding of
the Securities. Subject to certain exceptions set forth in the Indenture,
without the consent of any Securityholder, the Company and the Trustee may amend
the Indenture or the Securities to cure any ambiguity, omission, defect or
inconsistency, or to comply with Article V of the Indenture, or to provide for
uncertificated Securities in addition to or in place of certificated Securities,
or to add guarantees with respect to the Securities or to secure the Securities,
or to release Guarantor Subsidiaries when permitted by the Indenture or to add
additional covenants or surrender rights and powers conferred on the Company, or
to comply with any request of the SEC in connection with qualifying the
Indenture under the Act, or to make certain changes in the subordination
provisions, or to make any change that does not adversely affect the rights of
any Securityholder.

14. Defaults and Remedies

            Under the Indenture, Events of Default include (i) default for 30
days in payment of interest on the Securities; (ii) default in payment of
principal on the Securities at maturity, upon redemption pursuant to paragraph 5
of the Securities, or failure by the Company to redeem or purchase, upon
declaration or otherwise (whether or not such payment is prohibited by Article
X), Securities when required; (iii) failure by the Company or any Guarantor
Subsidiary to comply with other agreements in the Indenture or the Securities,
in certain cases subject to notice and lapse of time; (iv) certain accelerations
   151
                                                                               9


(including failure to pay within any grace period after final maturity) of other
Indebtedness of the Company if the amount accelerated (or so unpaid) exceeds
$5,000,000 or its foreign currency equivalent; (v) certain events of bankruptcy,
insolvency or reorganization with respect to the Company and its Restricted
Subsidiaries; and (vi) certain judgments or decrees not covered by insurance for
the payment of money in excess of $5,000,000 or its foreign currency equivalent
against the Company or a Restricted Subsidiary; and (vii) a Subsidiary Guaranty
ceasing to be in full force and effect (other than in accordance with its terms)
or any Guarantor Subsidiary denies or disaffirms its obligations under the
Indenture or any Subsidiary Guaranty and such Default continues for 10 days. If
an Event of Default occurs and is continuing, the Trustee or the Holders of at
least 25% in principal amount of the Securities may declare all the Securities
to be due and payable immediately. Certain events of bankruptcy or insolvency
are Events of Default which will result in the Securities being due and payable
immediately upon the occurrence of such Events of Default.

            Securityholders may not enforce the Indenture or the Securities
except as provided in the Indenture. The Trustee may refuse to enforce the
Indenture or the Securities unless it receives reasonable indemnity or security.
Subject to certain limitations, Holders of a majority in principal amount of the
Securities may direct the Trustee in its exercise of any trust or power. The
Trustee may withhold from Securityholders notice of any continuing Default
(except a Default in payment of principal, premium, if any, or interest) if and
so long as a committee of its Trust Officers in good faith determines that
withholding notice is in the interest of the Holders.

15. Trustee Dealings with the Company

            Subject to certain limitations imposed by the Act, the Trustee under
the Indenture, in its individual or any other capacity, may become the owner or
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.

   152
                                                                              10


16. No Recourse Against Others

            A director, officer, employee or stockholder, as such, of the
Company or any Guarantor Subsidiary shall not have any liability for any
obligations of the Company or a Guarantor Subsidiary 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 Securityholder
waives and releases all such liability. The waiver and release are part of the
consideration for the issue of the Securities.

17. Governing Law

            THE SECURITIES 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.

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 Securityholder
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).

20. CUSIP Numbers

            Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures the Company has caused CUSIP numbers to be
printed on the Securities and has directed the Trustee to use CUSIP numbers in
notices of redemption as a convenience to Securityholders. No representation is
made as to the accuracy of such numbers either 
   153
                                                                              11

Neenah Corporation
c/o United States Trust Company of New York
114 West 47th Street
New York, NY 10036

Dear Ladies and Gentlemen:

            This certificate is delivered to request a transfer of $ principal
amount of the 11-1/8% Senior Subordinated Notes due 2007 (the "Securities") of
Neenah Corporation (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 risk of our investment in the Securities
and 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.

   158
                                                                               2


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 which is two years after the later of the date of original
issue and the last date on which the Company or any affiliate of the Company was
the owner of such Securities (or any predecessor thereto) (the "Resale
Restriction Termination Date") only (a) to the Company, (b) pursuant to a
registration statement which has been declared effective under the Securities
Act, (c) in a transaction complying with the requirements of Rule 144A under the
Securities Act, to a person we reasonably believe is a qualified institutional
buyer under Rule 144A (a "QIB") that purchases for its own account or for the
account of a QIB and to whom notice is given that the transfer is being made in
reliance on Rule 144A, (d) pursuant to offers and sales that occur outside the
United States within the meaning of Regulation S under the Securities Act or (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 transaction involving 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
