to the Depository or another nominee of the Depository or by the Depository

PERSON IS WRONGFUL inasmuch as the registered owner hereof, Cede & Co., has

         1. INTEREST. Falcon Building Products, Inc., a Delaware corporation

Liquidated Damages payable pursuant to Section 5 of the Registration Rights 
Agreement referred to below. The Company will pay interest and Liquidated 
Damages semi-annually on June 15 and December 15 of each year, or if any such 
day is not a Business Day, on the next succeeding Business Day (each an 
"INTEREST PAYMENT DATE"). Interest on the Notes will accrue from the most 
recent date to which interest has been paid or, if no interest has been paid, 
from the date of issuance; PROVIDED that if there is no existing Default in 
the payment of interest, and if this Note is authenticated between a record 
date referred to on the face hereof and the next succeeding Interest Payment 
Date, interest shall accrue from such next succeeding Interest Payment Date; 
PROVIDED, FURTHER, that the first Interest Payment Date shall be December 15, 
1997. The Company shall pay interest (including post-petition interest in any 
proceeding under any Bankruptcy Code) on overdue principal and premium, if 
any, from time to time on demand at a rate that is 1% per annum in excess of 
the rate then in effect; it shall pay interest (including post-petition 
interest in any proceeding under any Bankruptcy Code) on overdue installments 
of interest and Liquidated Damages (without regard to any applicable grace 
periods) from time to time on demand at the same rate to the extent lawful. 
Interest will be computed on the basis of a 360-day year of twelve 30-day 
months.

         2. METHOD OF PAYMENT. The Company will pay interest on the Notes 
(except defaulted interest) and Liquidated Damages to the Persons who are 
registered Holders of Notes at the close of business on June 1 or December 1 
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, interest and Liquidated 
Damages at the office or agency of the Company maintained for such purpose 
within or without the City and State of New York, or, at

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, premium and Liquidated Damages on, all Global Notes and all other 
Notes the Holders of which shall have provided wire transfer instructions to

tender for payment of public and private debts.

Bank, 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 June 17, 1997 (the "INDENTURE") between the Company and the Trustee. 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 unsecured general obligations of the Company limited to

occurrence of a Change of Control, upon not less than 30 nor more than 60

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 (the "CHANGE OF CONTROL PAYMENT") equal to 
101% of the aggregate principal amount thereof plus accrued and unpaid 
interest and Liquidated Damages thereon, if any, to the date of purchase.

               (b)  If the Company or any Subsidiary consummates one or more 
Asset Sales and does not use all of the Net Proceeds from such Asset Sales as 
provided in Section 4.10 of the Indenture, the Company will be required, 
under certain circumstances, to utilize the Excess Proceeds from such Asset 
Sales to offer (an "EXCESS PROCEEDS OFFER") to purchase Notes at a purchase 
price in cash equal to 100% of the aggregate principal amount of the Notes 
plus any accrued and unpaid interest and Liquidated Damages, if any, to the

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 whole 
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.

          9. DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered form
without coupons in denominations of $1,000 and integral multiples of $1,000. The

the unredeemed portion of any Note being redeemed in part. Also, it need not
exchange or register the transfer of any Notes for a period of 15 days before a
selection of Notes to be redeemed or during the period between a record date
and the corresponding Interest Payment Date.

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

          11. AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain 
exceptions, the Indenture or the Notes may be amended or supplemented with 
the consent of the Holders of at least a majority in principal amount of the 
then outstanding Notes, and any existing default or compliance with any 
provision of the Indenture or the Notes 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 or the Notes may 
be amended or supplemented to cure any ambiguity, defect or inconsistency, to 
provide for uncertificated Notes in addition to or in place of certificated 
Notes, to provide for the assumption of the Company's 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 Trust Indenture Act.

          12. DEFAULTS AND REMEDIES. Events of Default include: (a) default

if any, on the Notes (whether or not prohibited by Article 10 of the 
Indenture); (c) failure by the Company for 30 days after notice to comply 
with the provisions described under Sections 4.07, 4.09, 4.10, 4.15 or 5.01

comply with any of its other agreements in the Indenture or the Notes; (e) 
the failure by the Company or any Restricted Subsidiary that is a Significant 
Subsidiary to pay any Indebtedness within any applicable grace period after 
final maturity or acceleration by the holders thereof because of a default if 
the total amount of such Indebtedness unpaid or accelerated exceeds $20.0 
million; (f) the failure by the Company or any of its Restricted Subsidiaries 
that is a Significant Subsidiary to pay final non-appealable judgments 
aggregating in excess of $20.0


                                          5


million, which judgments are not paid, discharged or stayed for a period of 
60 days; (g) except as permitted by the Indenture, any Subsidiary Guarantee 
by a Guarantor that is a Significant Subsidiary shall be held in any judicial 
proceeding to be unenforceable or invalid or shall cease for any reason to be 
in full force and effect or any Guarantor, or any Person acting on behalf of 
any Guarantor, shall deny or disaffirm its obligations under its Subsidiary 
Guarantee; and (h) certain events of bankruptcy or insolvency with respect to 
the Company or any of its Restricted Subsidiaries that is a Significant 
Subsidiary. If any Event of Default occurs and is continuing, the Note 
Trustee or the Holders of at least 25% in principal amount of the then 
outstanding Notes may declare all the Notes to be due and payable 
immediately. Notwithstanding the foregoing, in the case of an Event of 
Default arising from certain events of bankruptcy or insolvency with respect 
to the Company or any of its Restricted Subsidiaries that is a Significant 
Subsidiary, all outstanding Notes will become due and payable without further 
action or notice. Holders of the Notes may not enforce this 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 applicable 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 or interest) if it determines that withholding 
notice is in their interest.

          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

to Minors Act).

          17. ADDITIONAL RIGHTS OF HOLDERS OF TRANSFER RESTRICTED SECURITIES. In

of Transferred Restricted Securities shall have all the rights set forth in the
Registration Rights Agreement dated as of June 17, 1997, between the Company and
the parties named on the signature pages thereof (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 


                                          6


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
