Owens Corning By: -------------------------------- Name: Title: By: -------------------------------- Name: Title: Attest: --------------------------- Name: Title: -3- This Security is one of a duly authorized issue of securities of the Company (herein called the "Securities"), issued and to be issued in one or more series under an Indenture, dated as of May 5, 1997 (herein called the "Indenture"), between the Company and The Bank of New York, as Trustee (herein called the "Trustee", which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof, limited in aggregate principal amount to $300,000,000. The Securities of this series are subject to redemption upon not less than 30 nor more than 60 days' notice by mail, in whole or in part, at the option of the Company at any time at a redemption price equal to the greater of (i) 100% of the principal amount of such Securities or (ii) the sum of the present values of the remaining scheduled payments of principal and interest thereon (not including the portion of any such payments of interest accrued as of the redemption date) discounted to the redemption date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate (determined on the third Business Day preceding such redemption date), plus, in each case, accrued and unpaid interest thereon to the redemption date. "Adjusted Treasury Rate" means the arithmetic mean of the yields under the heading "Week Ending" published in the Statistical Release most recently published prior to the date of determination under the caption "Treasury Constant Maturities" for the maturity (rounded to the nearest month) corresponding to the remaining life to maturity, as of the redemption date, of the principal being redeemed, plus 0.25%. If no maturity set forth under such heading exactly corresponds to the maturity of such principal, yields for the two published maturities most closely corresponding to the maturity of such principal shall be calculated pursuant to the immediately preceding sentence, and the Adjusted Treasury Rate shall be interpolated or extrapolated from such yields on a straight-line basis, rounding in each of the relevant periods to the nearest month. "Statistical Release" means the statistical release designated "H.15(519)" or any successor publication which is published weekly by the Federal Reserve System and which establishes yields on actively-traded United States government securities adjusted to constant maturities, or, if such statistical release is not published at the time of any determination under the terms of the Securities, then such other reasonably comparable index which shall be designated by the Company.

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture. The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security. No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.

The Securities of this series are issuable only in registered form without coupons in denominations of $1,000 and any integral multiple thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like -5- tenor of a different authorized denomination, as requested by the Holder surrendering the same. No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.
