Consequences of Merger Events:

	Share-for-Share:	Alternative Obligation

	Share-for-Combined:	Notwithstanding anything herein, in the Agreement or in the Equity Definitions to the contrary, if a Merger Event occurs for which the Other Consideration received by the shareholders of the Issuer includes any Excluded Consideration (as defined below), to the extent that the Put or Call remains unexercised at the closing of a Merger Event, the Transaction will be terminated as of such time and neither Counterparty nor Lehman shall be required to make any payment or any delivery in respect of the portion of the Put or Call that has not been exercised prior to the Merger Date. “Excluded Consideration” shall mean anything other than US Dollars, New Shares or Public Securities Consideration (as defined below).

		Notwithstanding anything herein, in the Agreement or in the Equity Definitions to the contrary, subject to the immediately succeeding paragraph, if a Merger Event occurs, for which the consideration received by shareholders of the Issuer includes only (a) cash and/or Public Securities Consideration (as defined below) and (b) New Shares, then (i) the Strike Price for the Put and the Call shall, effective on the Merger Date in respect of such Merger Event, be reduced by the sum


				of the amount of any cash and the market price of any Public Securities Consideration, as determined by the Calculation Agent, received by Counterparty in such Merger Event in respect of one Share; provided, however, that the Strike Price shall never be reduced to less than zero, and (ii) the consequences set forth above opposite Share-for-Share shall apply to that portion of the consideration that consists of New Shares as determined by the Calculation Agent. “Public Securities Consideration” shall mean any securities (other than New Shares) quoted, traded or listed on any of the New York Stock Exchange, the American Stock Exchange, The NASDAQ Global Select Market, The NASDAQ Global Market or The NASDAQ Capital Market or any other publicly traded security for which a quotation is available on TRACE or another similar pricing service, as determined by the Calculation Agent.

				Notwithstanding anything herein, in the Agreement or in the Equity Definitions to the contrary, for purposes of the Put, in the event that shareholders of the Issuer are entitled to make an election with respect to the type of consideration to be received in a Share-for-Combined Merger Event of the type described in the two immediately preceding paragraphs, the consideration for each Share shall be deemed to be the per Share consideration received with respect to a plurality of the Shares in the Merger Event. In such event, Owens Corning shall provide Lehman with prompt notice of such consideration for the Shares. For purposes of the Call, the consideration for the Shares in a Share-for-Combined Merger Event shall be deemed to be the actual consideration received by Counterparty.

Additional Disruption Events:		No Additional Disruption Events shall apply to the Transaction or this Confirmation except a Change in Law (as defined herein). If a Change in Law occurs and either party elects to terminate the Transaction pursuant to Section 12.9(b)(i) of the Equity Definitions, then such termination shall apply to this Transaction in its entirety and may not apply solely to the Put or solely to the Call.

	Insolvency Filing:	Not Applicable

3. CONDITIONS PRECEDENT

Each of the following shall be a condition precedent (the “Conditions Precedent”) to the effectiveness of this Transaction:

(i)

The Effective Date (as defined in the Plan of Reorganization) shall have occurred;

	(ii)		The FAIR Act shall not have been enacted and become law on or before the date that is ten (10) days after the conclusion of the 109^th United States Congress (the “Trigger Date”); or if the FAIR Act has been enacted and become law prior to the Trigger Date, but has been challenged in a court of competent jurisdiction on or before March 31, 2007, such challenge ultimately succeeds pursuant to a non-appealable final order of such court resulting in the FAIR Act no longer being in effect;

	(iii)		Owens Corning has delivered to the Trust the 28.2 million Reserved New OCD Shares (as defined in the Plan of Reorganization) on or prior to the Outside Commencement Date, and all such Shares shall have been validly issued, fully paid, non-assessable and free and clear of all taxes, liens pre-emptive rights, rights of first refusal, subscription and similar rights except that such Shares shall be subject to put and call agreements contemplated by the Plan of Reorganization, including this Confirmation;

	(iv)		The Shares shall have been publicly quoted, traded or listed on any of the New York Stock Exchange, the American Stock, The NASDAQ Global Select Market, The NASDAQ Global Market or The NASDAQ Capital Market (or their respective successors);

	(v)		Owens Corning shall have sold 72.9 million Shares for aggregate cash proceeds of at least USD 2.187 billion; and

	(vi)		The Trust has provided to Lehman by no later than five Scheduled Trading Days following the Effective Date, (i) an executed counterpart of this Confirmation and (ii) an opinion of counsel to the effect of the matters set forth in Exhibit B hereto, provided that such opinion may be subject to customary exceptions reasonably acceptable to Lehman (collectively, the “Document Delivery Condition”);

If (i) this Confirmation has not been approved by the Bankruptcy Court on or prior to the entry of the Confirmation Order (as defined in the Plan of Reorganization) in respect of the Plan of Reorganization; (ii) the FAIR Act has been enacted and becomes law prior to the Trigger Date, but has not been challenged in a court of competent jurisdiction on or before March 31, 2007; or (iii) any of the above Conditions Precedent are not fulfilled prior to the Outside Commencement Date, then this Transaction shall terminate for no value and neither party shall have any rights or obligations hereunder.

4. DIVIDEND ADJUSTMENTS

If at any time during the period from and excluding the Effective Date (as defined in the Plan of Reorganization), to and including the Expiration Date, an ex-dividend date for which a cash dividend relates (regardless of when paid by the Issuer to holders of the Shares) occurs with respect to the Shares (an “Ex-Dividend Date”) and that dividend is greater than the Regular Dividend (as defined below) on a per Share basis, then the Forward Dividend Adjustment Value of the difference between the per Share cash dividend corresponding to that Ex-Dividend Date and the Regular Dividend shall be subtracted from the Put Strike Price and the Call Strike Price, effective as of such Ex-Dividend Date. “Regular Dividend” shall mean USD 0.18 per Share per quarter.

For purposes hereof, “Forward Dividend Adjustment Value” with respect to a cash dividend paid on the Shares shall be calculated from the Ex-Dividend Date through and including the Expiration Date using an interest rate equal to the mid-market interpolated US dollar zero coupon swap rate with a maturity corresponding to the Expiration Date as determined by Lehman.

5. PARTIAL OR WHOLE SETTLEMENT DELAYS

Notwithstanding any other provisions hereof, Lehman shall not be entitled to receive Shares or any other class of voting securities of the Issuer (whether in connection with the purchase of Shares on any Settlement Date or otherwise) (i) to the extent (but only to the extent) that, after such receipt, Lehman would directly or indirectly beneficially own (as such term is defined for purposes of Section 13(d) of the Securities Exchange Act of 1934 (the

“Exchange Act”)) in excess of 9.0% of the outstanding Shares or any other class of voting securities of the Issuer (the “9.0% Limit”) or (ii) if any applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), shall not have expired or been terminated with respect to the acquisition of Shares hereunder (the “HSR Condition”). Any purported delivery hereunder shall be void and have no effect to the extent (but only to the extent) that after such delivery (i) Lehman would directly or indirectly so beneficially own in excess of 9.0% of the outstanding Shares or any other class of voting securities of the Issuer or (ii) the HSR Condition has not been satisfied, as the case may be. If any delivery owed to Lehman hereunder is not made, in whole or in part, as a result of this provision, the Trust’s obligation to make such delivery shall not be extinguished and the Trust shall make such delivery as promptly as practicable after, but in no event later than one Clearance System Business Day after, Lehman gives notice to the Trust that after such delivery (i) Lehman would not directly or indirectly so beneficially own in excess of 9.0% of the outstanding Shares or any other class of voting securities of the Issuer or (ii) the HSR Condition has been satisfied, as the case may be. Lehman shall pay the Strike Price to the Trust not later than the Settlement Date with respect to any Options exercised on the same basis as if the Trust made delivery of the Shares upon such exercise even if delivery of the Shares does not take place by such Settlement Date due to the applicability of this Section 5. In the event that the delivery of Shares cannot be made due to either the HSR Condition not being satisfied or the 9.0% Limit being exceeded, at the request of Lehman, the Trust shall enter into a customary and reasonable escrow arrangement relating to the Shares compliant with the HSR Act (if applicable) and any other applicable legal or regulatory requirements. Lehman and Owens Corning (i) shall use reasonable best efforts to prepare and file all necessary documentation and to effect all applications that are necessary or advisable under the HSR Act so that the applicable waiting period shall have expired or been terminated thereunder with respect to the acquisition of Shares hereunder and (ii) shall not take any action that is intended or reasonably likely to materially impede or delay the ability of the parties to obtain any necessary approvals required for the transactions contemplated hereunder; provided that no such actions shall be required if Lehman determines that the acquisition of Shares hereunder would not be reasonably expected to require a filing under the HSR Act.

6. TRANSFER OR ASSIGNMENT

Counterparty may not transfer any of its rights or obligations under this Transaction without the prior written consent of Lehman, except for the assignment to the Trust described above. Notwithstanding anything to the contrary in the Agreement, Lehman may transfer or assign all or any portion of its rights or obligations under this Transaction without the consent of Counterparty to either (i) any affiliate of Lehman; provided that the obligations of such affiliate hereunder and under the Agreement are wholly and unconditionally guaranteed, prior to any transfer or assignment, by Lehman Brothers Holdings Inc. in a form acceptable to the Trust or (ii) any party specified on Schedule 1 hereto with a Credit Rating (as defined herein) that is, at the time of the relevant transfer, (a) A+ or higher by S&P or (b) Aa3 or higher by Moody’s; provided, that any such transferee or assignee shall be subject to the requirements (i) to make the representation set forth in Section 7(e) hereof and (ii) to deliver any Tax forms reasonably requested by Counterparty; provided, also, that if such transferee or assignee is a Broker (as defined in 3(a)(4) of the Exchange Act) or a Dealer (as defined in 3(a)(5) of the Exchange Act), Lehman may only transfer or assign rights or obligations under this Transaction to such transferee or assignee with the prior written consent of Counterparty and, prior to the Assignment Effective Date, the FCR and C&D (as defined below). Notwithstanding any other provision in this Confirmation to the contrary requiring or allowing Lehman to purchase, sell, receive or deliver any Shares or other securities to or from Counterparty, Lehman may designate any of its affiliates to purchase, sell, receive or deliver such Shares or other securities and otherwise to perform Lehman’s obligations in respect of this Transaction and any such designee may assume such obligations. Lehman shall be discharged of its obligations to Counterparty solely to the extent of any such performance.

For purposes of the foregoing, the “Credit Rating” of a party means the rating of a party assigned by either S&P or Moody’s to such party’s long term, unsecured and unsubordinated indebtedness or deposits.

7. ADDITIONAL TERMS

(a) Additional Termination Events: It shall constitute an Additional Termination Event where this Transaction is the sole Affected Transaction and Counterparty shall be deemed to be the sole Affected Party, if Counterparty shall have been dissolved, wound-up, liquidated or terminated or, from and after the Assignment Effective Date, in the case of the Trust, the Trust does not have any duly appointed trustees to control the exercise of the powers, authorities and discretions of the Trust.

Notwithstanding anything to the contrary contained in the Agreement, the Equity Definitions or this Confirmation, breach of a covenant, agreement, obligation or representation or warranty of or by Owens Corning or the failure of Owens Corning to make any delivery required hereby shall not give rise to a right of Lehman to terminate the Transaction or any liability to the Trust or entitle any person or entity to any damages, payments or performance from the Trust.

GUARANTEE OF LEHMAN BROTHERS HOLDINGS INC.

LEHMAN BROTHERS OTC DERIVATIVES INC. (“Party A”) and OWENS CORNING (“Party B”) have entered into a transaction (the “Transaction”) under the Confirmation dated July 7, 2006 (the “Confirmation”) and the ISDA Master Agreement incorporated therein by reference, as amended from time to time (collectively referred to as the “Agreement”). This Guarantee is a Credit Support Document as contemplated in the Agreement. Guarantor agrees that Owens Corning shall assign its rights under the Agreement to the Asbestos Personal Injury Trust (as defined in Owens Corning’s Plan of Reorganization), except to the extent provided in the Agreement, and, accordingly, the Asbestos Personal Injury Trust shall on and after the Assignment Effective Date (as defined in the Agreement) be Party B hereunder and entitled to all of the rights and benefits of Party B hereunder. For value received, and in consideration of the financial accommodation accorded to Party A by Party B under the Agreement, LEHMAN BROTHERS HOLDINGS INC., a corporation organized and existing under the laws of the State of Delaware (“Guarantor”), hereby agrees to the following:

(a) Guarantor hereby irrevocably and unconditionally guarantees to Party B, its successors and assigns the due and punctual and complete payment of all amounts payable by Party A in connection with the Transaction when and as Party A’s obligations thereunder shall become due and payable in accordance with the terms of the Agreement (whether at maturity, by acceleration or otherwise). Guarantor hereby agrees, upon written demand by Party B, to pay or cause to be paid any such amounts punctually when and as the same shall become due and payable.

(b) Guarantor hereby agrees that its obligations under this Guarantee constitute a guarantee of payment and not of collection.

(c) Guarantor hereby agrees that its obligations under this Guarantee shall be unconditional, irrespective of the validity, regularity or enforceability of the Agreement against Party A (other than as a result of the unenforceability thereof against Party B), the absence of any action to enforce Party A’s obligations under the Agreement, any waiver or consent by Party B with respect to any provisions thereof, the entry by Party A and Party B into any amendments to the Agreement, additional transactions under the Agreement or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor (excluding the defense of payment or statute of limitations, neither of which is waived). The Guarantor acknowledges that Party A and Party B may from time to time enter into one or more transactions pursuant to the Agreement and agrees that the obligations of the Guarantor under this Guarantee will upon the execution of any such transactions by Party A and Party B extend to all such transactions without the taking of further action by the Guarantor.

(d) This Guarantee shall remain in full force and effect until all the obligations of Party A under the Agreement have been fully and completely satisfied.

(e) Guarantor further agrees that this Guarantee shall continue to be effective or be reinstated, as the case may be, if at any time, payment, or any part thereof, of any obligation or interest thereon is rescinded or must otherwise be restored by Party B.

(f) Guarantor hereby waives (i) promptness, diligence, acceptance, presentment, demand of payment, protest, order and, except as set forth in paragraph (a) hereof, notice of any kind in connection with the Agreement and this Guarantee, or (ii) any requirement that Party B exhaust any right to take any action against Party A or any other person prior to or contemporaneously with proceeding to exercise any right against Guarantor under this Guarantee.

(g) The Guarantor agrees that Party B, may at any time and from time to time, either before or after the maturity thereof, without notice to or further consent of the Guarantor, extend the time of payment of, exchange or surrender any collateral for, or renew any of the obligations of Party A under the Agreement, and may also make any agreement with Party A or with any other party to or person liable on any such obligations, or interested therein, for the extension, renewal, payment, compromise, discharge or release thereof, in whole or in part, or for any modification of the terms thereof or of any agreement between Party A and Party B or any such other party or person, without in any way impairing or affecting this Guarantee. The Guarantor agrees that Party B may resort to the Guarantor for payment or performance of any of the obligations of Party A under the Agreement, whether or not Party B shall have resorted to any collateral security, or shall have proceeded against any other obligor principally or secondarily obligated with respect to any of the obligations of Party A under the Agreement.

(h) The Guarantor will not exercise any rights which it may acquire by way of subrogation until all obligations of Party A under the Agreement to Party B shall have been paid in full. If any amount shall be paid to the Guarantor in violation of the preceding sentence, such amount shall be held for the benefit of Party B and shall forthwith be paid to Party B to be credited and applied to the obligations of Party A under the Agreement, whether matured or unmatured. Subject to the foregoing, upon payment and performance of all obligations of Party A under the Agreement in full, the Guarantor shall be subrogated to the rights of Party B against Party A and Party B agrees to take at the Guarantor’s expense such steps as the Guarantor may reasonably request to implement such subrogation.

(i) No failure on the part of Party B to exercise, and no delay in exercising, any right, remedy or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise by Party B of any right, remedy or power hereunder preclude any other future exercise of any right, remedy or power. Each and every right, remedy and power hereby granted to Party B or allowed it by law or other agreement shall be cumulative and not exclusive of any other, and may be exercised by Party B from time to time or at any time.

(j)

(iii) No consent, licenses, approvals and authorizations of and registrations with or declarations to any governmental authority under any federal law in the United States or Delaware General Corporation Law are required in connection with the execution, delivery and performance of this Guarantee.
