from the date of issuance until maturity; provided, however, that at the option
of the Company, so long as no Default or Event of Default is then continuing,

<PAGE>

Company will pay interest semi-annually on February 15 and August 15 of each
year, or if any such day is not a Business Day, on the next succeeding Business
Day (each an "Interest Payment Date") to the holder of record on the immediately
preceding February 1 or August 1 (each, a "Record Date"). Interest on the Notes
will accrue from the most recent date to which interest has been paid or, if no
interest has been paid, from the date of issuance, or in case of Additional
Notes, from the date of issuance of such Additional Notes; provided that if
there is no existing Default in the payment of interest, and if this Note is
authenticated between a Record Date and the next succeeding Interest Payment
Date, interest shall accrue from such next succeeding Interest Payment Date;
provided, further, that the first Interest Payment Date shall be February 15,
2002. The Company shall pay interest (including Accrued Bankruptcy Interest in
any proceeding under any Bankruptcy Law) on overdue principal and premium, if
any, from time to time on demand at a rate that is 2% per annum in excess of the
then applicable interest rate on the Notes to the extent lawful (the "Default
Rate"). In addition, the Company shall pay interest (including Accrued
Bankruptcy Interest in any proceeding under any Bankruptcy Law) on overdue
installments of interest (without regard to any applicable grace periods) from
time to time on demand at the Default Rate to the extent lawful. Interest will
be computed on the basis of a 360-day year of twelve 30-day months.

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

      If the Company elects to exercise its right to make an interest payment in
the form of Additional Notes, the Company must deliver to the Trustee, not less
than 10 nor more than 45 days prior to the Record Date for the Interest Payment
Date on which Additional Notes will be issued, an Officers' Certificate
notifying the Trustee of its election to pay interest through the issuance of
Additional Notes and the aggregate amount of such Additional Notes to be issued,
and specifying the amount of Additional Notes to be issued through the issuance
of Additional Definitive Notes, the amount to be issued through increases in the
Restricted Global Note and the amount to be issued through increases in the
Unrestricted Global Note. On or after the date of such Officers' Certificate but
not less than 10 days prior to the relevant Interest Payment Date, the Company
must deliver to the Trustee any Additional Definitive Notes to be issued, which
Additional Definitive Notes must have been duly executed by the Company in the
manner provided in Section 2.02 of the Indenture. If the Company has satisfied
the conditions set forth herein for the payment of interest in the form of
Additional Notes on the relevant Interest Payment Date, the Trustee will record
increases in the Global Notes and authenticate Additional Definitive Notes, as
appropriate, in the aggregate principal amounts required to pay such interest.

                                       A-3

<PAGE>

          Each Additional Note is an additional obligation of the Company and
the Subsidiary Guarantors and shall be governed by, and entitled to the benefits
of, the Indenture and shall be subject to the terms of the Indenture (including
the guarantee provisions) and shall rank pari passu with and be subject to the
same terms (including the rate of interest from time to time payable thereon) as
this Note (except, as the case may be, with respect to the issuance date and
aggregate principal amount) and shall have the benefit of all Liens securing
Notes.

          3.  Paying Agent and Registrar. Initially, State Street Bank and Trust
Company, the Trustee under the Indenture, will act as Paying Agent and
Registrar. The Company may change any Paying Agent or Registrar without notice
to any Holder. The Company or any of its Subsidiaries may act in any such
capacity.

          4.  Indenture. The Company issued the Notes under an Indenture dated
as of August 23, 2001 among the Company, the Subsidiary Guarantors and the
Trustee (as such may be amended or supplemented from time to time, the
"Indenture"). The terms of the Notes include those stated in the Indenture and
those made part of the Indenture by reference to the Trust Indenture Act of
1939, as amended (15 U.S. Code Sections 77aaa-77bbbb). The Notes are subject to
all such terms, and Holders are referred to the Indenture and such Act for a
statement of such terms. The Notes are secured obligations of the Company
limited to $25,000,000 in aggregate principal amount (except as otherwise
provided in Section 2 of this Note relating to payment of interest by issuance
of Additional Notes).

          5.  Optional Redemption. The Company shall have the option to redeem
the Notes, in whole or in part, at any time and from time to time, at the
redemption price of 101% of principal amount, plus accrued and unpaid interest
thereon, if any, to the applicable redemption date.

          Notice of redemption will be mailed at least 30 days but not more than
60 days before the redemption date to each Holder whose Notes are to be redeemed
at its registered address. Notes in denominations larger than $1,000 may be
redeemed in part but only in integral multiples of $1,000, unless all of the
Notes held by a Holder are to be redeemed. On and after the redemption date
interest ceases to accrue on Notes or portions thereof called for redemption.

          6.  Mandatory Redemption. The Company shall not be required to make
mandatory redemption payments with respect to the Notes.

          7.  Repurchase Offers.

              (a)  Change of Control Offer. Upon the occurrence of a Change of
Control, the Company shall offer to repurchase all or any part (equal to $1,000
or an integral multiple thereof) of such Holder's Notes pursuant to the offer
described below (the "Change of Control Offer") at an offer price in cash equal
to 101% of the aggregate principal amount thereof plus accrued and unpaid
interest thereon to the date of purchase (the "Change of Control Payment").
Within 30 days following any Change of Control, the Company shall mail a notice
to each Holder describing the transaction or transactions that constitute the
Change of Control and offering to repurchase Notes pursuant to the procedures
required by the Indenture and described in such notice. The Company shall comply
with the requirements of Rule 14e-1 under the

                                       A-4

<PAGE>

Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the
repurchase of the Notes as a result of a Change of Control.

          (b)   Asset Sale Offer. The Company shall not, and shall not permit
any of its Subsidiaries to, engage in an Asset Sale in excess of $1,000,000
unless (a) the Intercreditor Agreement is in effect and does not prohibit such
Asset Sale and expressly provides that the Trustee has no right to restrict or
permit, or approve or disapprove, such Asset Sale, or (b) in all other cases (i)
the Company (or the Subsidiary, as the case may be) receives consideration at
the time of such Asset Sale at least equal to the fair market value, and in the
case of a lease of assets, a lease providing for rent and other conditions which
are no less favorable to the Company (or the Subsidiary, as the case may be) in
any material respect than the then prevailing market conditions (evidenced in
each case by a resolution of the Board of Directors of such entity set forth in
an Officers' Certificate delivered to the Trustee) of the assets or Equity
Interests sold or otherwise disposed of, (ii) at least 75% (100% in the case of
lease payments) of the consideration therefor received by the Company or such
Subsidiary is in the form of cash or Cash Equivalents; provided that the amount
of any notes or other obligations received by the Company or any such Subsidiary
from such transferee that are promptly, but in no event more than 30 days after
receipt, converted by the Company or such Subsidiary into cash (to the extent of
the cash received), shall be deemed to be cash for purposes of this provision,
(iii) subject to the Intercreditor Agreement, if such Asset Sale involves the
disposition of Collateral, the Company or such Subsidiary has complied with
Articles 10 and 11 of the Indenture, and (iv) the Company or the Subsidiary, as
the case may be, applies the Net Proceeds as provided in the following
paragraph.

          Subject to the Intercreditor Agreement, any such Net Proceeds may, at
the option of the Company, be applied within 180 days of the related Asset Sale
as follows:

                (i) to the acquisition of another business or the acquisition of
          other long-term assets, in each case, in the same or a similar line of
          business as the Company or any of its Subsidiaries was engaged in on
          the Issue Date or any reasonable extensions or expansions thereof
          ("Replacement Assets"); provided, that any Replacement Assets shall be
          owned by the Company or by the Subsidiary Guarantor that made the
          Asset Sale and shall not be subject to any Liens except Collateral
          Permitted Liens (and the Company or such Subsidiary Guarantor, as the
          case may be, shall execute and deliver to the Trustee such Collateral
          Documents or other instruments as shall be necessary to cause such
          Replacement Assets to become subject to a Lien in favor of the
          Trustee, for the benefit of the holders of the Notes, securing its
          obligations under the Notes or its Subsidiary Guarantee, as the case
          may be, and otherwise shall comply with the provisions of the
          Indenture applicable to After-Acquired Property); or

                (ii) to reimburse the Company or its Subsidiaries for
          expenditures made, and costs incurred, to repair, rebuild, replace or
          restore property subject to loss, damage or taking to the extent that
          the Net Proceeds consist of Net Insurance Proceeds received on account
          of such loss, damage or taking.

                                       A-5

<PAGE>

          Any portion of such Net Proceeds that is not used as described in
subparagraphs (i) or (ii) above within such 180-day period shall constitute
"Excess Proceeds" subject to disposition as provided below. When the aggregate
amount of Excess Proceeds exceeds $3,000,000, the Company shall be required to
make an offer to all Holders (an "Asset Sale Offer") to purchase the maximum
principal amount of Notes that may be purchased out of the Excess Proceeds, at
an offer price in cash in an amount equal to 100% of the principal amount
thereof plus accrued and unpaid interest thereon, if any, to the date of
purchase, in accordance with the procedures set forth in the Indenture. To the
extent that the aggregate amount of Notes tendered pursuant to an Asset Sale
Offer is less than the Excess Proceeds, the Company may use any remaining Excess
Proceeds for general corporate purposes. Upon completion of such Asset Sale
Offer, the amount of Excess Proceeds shall be reset at zero.

      8.  Denominations, Transfer, Exchange. The Notes are in registered form
without coupons in denominations of $1,000 and integral multiples of $1,000,
except that Notes may be originally issued in such denominations as may be
required under the Reorganization Plan or Section 4.01 of the Indenture and may
be subsequently transferred in such denominations. The transfer of Notes may be
registered and Notes may be exchanged as provided in the Indenture. The
Registrar and the Trustee may require a Holder, among other things, to furnish
appropriate endorsements and transfer documents and the Company may require a
Holder to pay any taxes and fees required by law or permitted by the Indenture.
Neither the Company nor the Registrar will be required (A) to issue, to register
the transfer of or to exchange any Notes during a period beginning at the
opening of business 15 days before the day of any selection of Notes for
redemption under Section 3.02 of the Indenture and ending at the close of
business on the day of selection, (B) to register the transfer of or to exchange
any Note so selected for redemption in whole or in part, except the unredeemed
portion of any Note being redeemed in part or (C) to register the transfer of or
to exchange a Note between a Record Date and the next succeeding Interest
Payment Date.

      9.  Persons Deemed Owners. The registered Holder of a Note may be treated
as its owner for all purposes.

      10. Amendment, Supplement and Waiver. Subject to certain exceptions, the
Indenture, the Notes or any Collateral Document may be amended or supplemented
with the consent of the Holders of at least a majority in principal amount of
the then outstanding Notes, and, subject to Sections 6.04 and 6.07 of the
Indenture, any existing Default or Event of Default (other than a Default or
Event of Default in the payment of the principal of, premium, if any, or
interest on the Notes, except a payment default resulting from an acceleration
that has been rescinded), or compliance with any provision of the Indenture, the
Notes or any Collateral Document, may be waived with the consent of the Holders
of a majority in principal amount of the then outstanding Notes. Without the
consent of any Holder of a Note, the Indenture, the Notes or the Collateral
Documents may be amended or supplemented to cure any ambiguity, defect or
inconsistency, to provide for the assumption of the Company's obligations to
Holders of the Notes in case of a merger or consolidation, to make any change
that would provide any additional rights or benefits to the Holders of the Notes
or that does not adversely affect the legal rights under the Indenture of any
such Holder, or to comply with the requirements of the SEC in order to effect or
maintain the qualification of the Indenture under the TIA.

                                      A-6

<PAGE>

      11. Defaults and Remedies. Each of the following constitutes an Event of
Default under the Indenture: (i) default for 15 days in the payment when due of
interest on the Notes; (ii) default in payment when due of the principal of or
premium, if any, on the Notes; (iii) failure by the Company or any of its
Subsidiaries to comply Sections 4.07, 4.08, 4.09, 4.10 or 4.14 of the Indenture;
(iv) failure by the Company or any of its Subsidiaries for 30 days after notice
to comply with any of its other agreements in the Indenture, the Notes, the
Subsidiary Guarantees or the Collateral Documents; (v) default under any
mortgage, indenture or instrument under which there may be issued or by which
there may be secured or evidenced any Indebtedness for money borrowed by the
Company or any of its Subsidiaries (or the payment of which is Guaranteed by the
Company or any of its Subsidiaries), whether such Indebtedness or Guarantee now
exists, or is created after the Issue Date, which default (a) is caused by a
failure to pay principal of or premium, if any, or interest on such Indebtedness
prior to the expiration of the grace period provided in such Indebtedness (a
"Payment Default") or (b) results in the acceleration of such Indebtedness prior
to its express maturity and, in each case, the principal amount of any such
Indebtedness, together with the principal amount of any other Indebtedness as to
which there has been a Payment Default or the maturity of which has been so
accelerated, aggregates $2,500,000 or more; (vi) failure by the Company or any
of its Significant Subsidiaries to pay final judgments aggregating in excess of
$2,500,000, which judgments are not paid, discharged or stayed for a period of
30 days; (vii) default by the Company or any Subsidiary in the performance of
the Collateral Documents which adversely affects the enforceability or validity
of the Lien in the Collateral or which adversely affects the condition or value
of the Collateral in any material respect, any repudiation or disaffirmation by
the Company or any Subsidiary of its Obligations under the Collateral Documents
or the determination in a judicial proceeding that any Collateral Document is
unenforceable or invalid against the Company or any of its Subsidiaries for any
reason; (viii) except as permitted by the Indenture, any Subsidiary Guarantee
shall be held in any judicial proceeding to be unenforceable or invalid or shall
cease for any reason to be in full force and effect or any Subsidiary Guarantor,
or any Person acting on behalf of any Subsidiary Guarantor, will deny or
disaffirm its obligations under its Subsidiary Guarantee; and (ix) certain
events of bankruptcy or insolvency with respect to the Company or any of its
Subsidiaries. Holders may not enforce the Indenture or the Notes except as
provided in the Indenture. Subject to certain limitations, Holders of a majority
in principal amount of the then outstanding Notes may direct the Trustee in its
exercise of any trust or power. The Trustee may withhold from Holders of the
Notes notice of any continuing Default or Event of Default (except a Default or
Event of Default relating to the payment of principal, premium, if any, or
interest) if it determines that withholding notice is in their interest. The
Holders of a majority in aggregate principal amount of the Notes then
outstanding by notice to the Trustee may on behalf of the Holders of all of the
Notes waive any existing Default or Event of Default and its consequences under
the Indenture except a continuing Default or Event of Default in the payment of
interest on, premium, if any, or the principal of, the Notes. The Company is
required to deliver to the Trustee annually a statement regarding compliance
with the Indenture, and the Company is required upon becoming aware of any
Default or Event of Default, to deliver to the Trustee a statement specifying
such Default or Event of Default.

      12. Ranking, Subsidiary Guarantees and Security. The Notes will rank pari
passu with all Indebtedness of the Company that is not subordinated to the
Notes, including borrowings under the New Credit Agreement. The Notes will rank
senior to any Indebtedness of the Company that is subordinated to the Notes. The
Notes will be unconditionally guaranteed on a

                                      A-7

<PAGE>

senior secured basis by each of the Subsidiary Guarantors. The Subsidiary
Guarantees will rank pari passu with all Indebtedness of the Subsidiaries
Guarantors that is not subordinated to such Subsidiary Guarantees, including
guarantees of borrowings under the New Credit Agreement. The Subsidiary
Guarantees will rank senior to any Indebtedness of the Subsidiary Guarantors
that is subordinated to such Subsidiary Guarantees. The Notes and the Subsidiary
Guarantees will be secured by second priority Liens on substantially all of the
assets of the Company and the Subsidiary Guarantors and the proceeds thereof,
whether now owned or hereafter acquired.

      13. Trustee Dealings with Company. The Trustee, in its individual or any
other capacity, may make loans to, accept deposits from, and perform services
for the Company or its Affiliates, and may otherwise deal with the Company or
its Affiliates, as if it were not the Trustee.

      14. No Recourse Against Others. A director, officer, employee,
incorporator or stockholder of the Company, as such, shall not have any
liability for any obligations of the Company under the Notes or the Indenture or
for any claim based on, in respect of, or by reason of, such obligations or
their creation. Each Holder by accepting a Note waives and releases all such
liability. The waiver and release are part of the consideration for the issuance
of the Notes.

      15. Authentication. This Note shall not be valid until authenticated by
the manual signature of the Trustee or an authenticating agent.

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

      17. Additional Rights of Holders of Transfer Restricted Notes. In addition
to the rights provided to Holders of Notes under the Indenture, Holders of
Transferred Restricted Notes shall have all the rights set forth in the
Registration Rights Agreement dated as of the Issue Date, among the Company, the
Subsidiary Guarantors and the holders of beneficial interests in the Restricted
Global Note (as such may be amended from time to time, the "Registration Rights
Agreement").

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

                         FORM OF SUPPLEMENTAL INDENTURE
                          TO BE DELIVERED BY SUBSEQUENT
                              SUBSIDIARY GUARANTORS

              Supplemental Indenture (this "Supplemental Indenture"), dated as
of ___________ _____ 200_, by and among __________________, a ___________
_________ (the "New Subsidiary Guarantor"), RBX Corporation (or its permitted
successor), a Delaware corporation (the "Company"), the other Subsidiary
Guarantors (as defined in the Indenture referred to herein), and State Street
Bank and Trust Company, as trustee under the Indenture referred to below (the
"Trustee").

                               W I T N E S S E T H

              WHEREAS, the Company has heretofore executed and delivered to the
Trustee an indenture (as such may be amended or supplemented from time to time,
the "Indenture"), dated as of August 23, 2001, providing for the initial
issuance of $25,000,000 of 12% Senior Secured Notes due 2006 and the subsequent
issuance of Additional Notes under Section 4.01 of the Indenture (collectively,
the "Notes");

              WHEREAS, Section 4.14 of the Indenture provides that under certain
circumstances newly-acquired or created Subsidiaries of the Company shall
unconditionally guarantee all of the Company's Obligations under the Notes and
the Indenture on the terms and conditions set forth herein (the "Subsidiary
Guarantee"); and

              WHEREAS, the New Subsidiary Guarantor is a Subsidiary of the
Company; and

              WHEREAS, pursuant to Section 9.01(c) of the Indenture, the
Company, the existing Subsidiary Guarantors and the Trustee are authorized to
execute and deliver this Supplemental Indenture.

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

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

       2.     Subsidiary Guarantees. Subject to the provisions of Article 12 of
the Indenture, the New Subsidiary Guarantor, jointly and severally together with
all other Subsidiary Guarantors (including, without limitation, each Subsidiary
Guarantor that becomes a party to the Indenture after the date hereof by
execution and delivery of a supplemental indenture), hereby unconditionally
guarantees to each Holder of a Note authenticated and delivered by the Trustee
(including, without limitation, all Additional Notes) and to the Trustee and its
successors and assigns, that: (a) the principal of, and premium, if any, and
interest on the Notes shall be duly and punctually paid in full when due,
whether at maturity, by acceleration or otherwise, and interest on overdue
principal, and premium, if any, and (to the extent permitted by law) interest on
any interest, if any, on the Notes and all other obligations of the Company to
the Holders or

                                      B-1

<PAGE>

the Trustee hereunder or under the Notes (including fees, expenses or other)
shall be promptly paid in full or performed, all in accordance with the terms
hereof; and (b) in case of any extension of time of payment or renewal of any
Notes or any of such other obligations, the same shall be promptly paid in full
when due or performed in accordance with the terms of the extension or renewal,
whether at stated maturity, by acceleration or otherwise (collectively, the
"Guarantee Obligations"). Failing payment when due of any Guarantee Obligation
or failing performance of any other obligation of the Company to the Holders,
for whatever reason, each Subsidiary Guarantor shall be obligated to pay, or to
perform or to cause the performance of, the same immediately. An Event of
Default under the Indenture or the Notes shall constitute an event of default
under the Subsidiary Guarantees, and shall entitle the Trustee or the Holders of
Notes to accelerate the Guarantee Obligations of each Subsidiary Guarantor in
the same manner and to the same extent as the Obligations of the Company. The
New Subsidiary Guarantor hereby agrees that its Guarantee Obligations hereunder
shall be unconditional, irrespective of the validity, regularity or
enforceability of the Notes or the Indenture, the absence of any action to
enforce the same, any waiver or consent by any Holder of the Notes with respect
to any thereof, the entry of any judgment against the Company, any action to
enforce the same or any other circumstance which might otherwise constitute a
legal or equitable discharge or defense of a guarantor.

       3.     Execution and Delivery. Each Subsidiary Guarantor agrees that the
Subsidiary Guarantees set forth in Article 12 of the Indenture and in any
supplemental indentures will remain in full force and effect and apply to all
the Notes notwithstanding any failure to endorse on each Note a notation of the
Subsidiary Guarantees, and notwithstanding any failure of any Subsidiary
Guarantor to execute such notation.

       4.     Subsidiary Guarantor May Consolidate, Etc. on Certain Terms. The
New Subsidiary Guarantor may not consolidate with or merge with or into another
Person except as permitted under Section 12.03 of the Indenture.

       5.     Releases. The New Subsidiary Guarantor may be released from its
obligations under its Subsidiary Guarantee in certain circumstances as provided
in the Indenture.

       6.     GOVERNING LAW. THE INTERNAL LAW OF THE STATE OF NEW YORK SHALL
GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL INDENTURE.

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

       8.     Effect of Headings. The Section headings herein are for
convenience only and shall not affect the construction hereof.

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

                                      B-2
