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 7 7 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 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.

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. 9 9 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. Sections 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 10 10 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 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, 11 11 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% 2003.................................... 103.7083% 2004.................................... 101.8542% 2005 and thereafter..................... 100.0000% Notwithstanding the foregoing, at any time 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 by the Company at a redemption price (expressed as a percentage of principal amount) of 111.125% plus accrued 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. 12 12 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 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 13 13 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.

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. 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 14 14 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 15 15 Securityholder, or to provide for the issuance and authorization of the Exchange Securities. 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 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. 16 16 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 with hold 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 other wise 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 17 17 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.

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 31 6 (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% 2003........................................ 103.7083% 2004........................................ 101.8542% 2005 and thereafter......................... 100.0000% 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 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. 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. 32 7 6.

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 33 8 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. 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. 34 9 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. 35 10 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 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 36 11 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. 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 37 12 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), TENENT (=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. 38 13 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.
