ARTICLE VIII

ADDITIONAL AGREEMENTS

Section 8.1 Tax Matters.

(a) Liability for Taxes.

(i) The Selling Stockholders shall be liable for and covenant to pay, and pursuant to Article XI (and subject to the limitations thereof) shall indemnify and hold harmless each Buyer Group Member from and against any and all Losses and Expenses incurred by such Buyer Group Member in connection with or arising from, any and all Taxes (A) imposed on any of the Companies pursuant to Treasury Regulation Section 1.1502-6 or similar provision of state or local law as a result of any Company having been a member of the Company Group, and (B) imposed on any of the Companies, or for which any of the Companies may otherwise be liable, for any taxable year or period that ends on or before the Closing Date and, with respect to any Straddle Period, the portion of such Straddle Period ending on and including the Closing Date; provided, however, that the Selling Stockholders shall not be liable for or pay, and shall not indemnify or hold harmless any Buyer Group Member from and against any Losses or Expenses incurred by any Buyer Group Member in connection with or arising from (A) any Taxes to the extent taken into account as a liability in the determination of Closing Date Working Capital, or (B) notwithstanding anything to the contrary herein, any Taxes resulting from a sale of any of the Companies by a Buyer (the Taxes described in this proviso being referred to as “Excluded Taxes”). The Selling Stockholders shall be entitled to any refund of (or credit for) Taxes allocable to any taxable year or period that

ends on or before the Closing Date and, with respect to any Straddle Period, the portion of such Straddle Period ending on and including the Closing Date.

(ii) The Buyers shall be liable for and covenant to pay, and pursuant to Article XI (and subject to the limitations thereof) shall indemnify and hold harmless each Seller Group Member from and against any and all Losses and Expenses incurred by such Seller Group Member in connection with or arising from, (A) any and all Taxes imposed on the Companies, or for which the Companies may otherwise be liable, for any taxable year or period that begins after the Closing Date and, with respect to any Straddle Period, the portion of such Straddle Period beginning after the Closing Date and (B) Excluded Taxes. Except as otherwise provided herein, the Buyers shall be entitled to any refund of (or credit for) Taxes described in clauses (A) and (B).

(iii) For purposes of Sections 8.1(a)(i) and (a)(ii), whenever it is necessary to determine the liability for Taxes of the Companies for a Straddle Period, the determination of such Taxes for the portion of the Straddle Period ending on and including, and the portion of the Straddle Period beginning after, the Closing Date shall be determined by assuming that the Straddle Period consisted of two taxable years or periods, one which ended at the close of the Closing Date and the other which began at the beginning of the day following the Closing Date, and items of income, gain, deduction, loss or credit of the Companies for the Straddle Period shall be allocated between such two taxable years or periods on a “closing of the books basis” by assuming that the books of the Companies were closed at the close of the Closing Date; provided, however, that (I) transactions occurring on the Closing Date that are properly allocable (based on, among other relevant factors, factors set forth in Treasury Regulation Section 1.1502-76(b)(1)(ii)(B)) to the portion of the Closing Date after the Closing shall be allocated to the taxable year or period that is deemed to begin at the beginning of the day following the Closing Date and (II) exemptions, allowances or deductions that are calculated on an annual basis, such as the deduction for depreciation, shall be apportioned between such two taxable years or periods on a daily basis.

(iv) If, as a result of any action, suit, investigation, audit, claim, assessment or amended Tax Return, there is any change after the Closing Date in an item of income, gain, loss, deduction, credit or amount of Tax that results in an increase in a Tax liability for which the Selling Stockholders would otherwise be liable pursuant to Section 8.1(a)(i), and such change results in or will result in a decrease in the Tax liability of the Companies, the Buyers or any Affiliate or successor thereof for any taxable year or period beginning after the Closing Date or for the portion of any Straddle Period beginning after the Closing Date, the Selling Stockholders shall not be liable pursuant to such Section 8.1(a)(i) with respect to such increase to the extent of such decrease (and, to the extent such increase in Tax liability is paid to a taxing authority by the Selling Stockholders or any Affiliate thereof, the Buyers shall pay the Selling Stockholders an amount equal to such decrease).

(v) Notwithstanding anything herein to the contrary, the Buyers and the Selling Stockholders shall each pay, and shall indemnify the other against 50% any real property transfer or gains Tax, sales Tax, use Tax, stamp Tax, stock transfer Tax, or other similar Tax imposed on the transactions contemplated by this Agreement.

(b) Tax Returns. (i) The Selling Stockholders shall timely file or cause to be timely filed when due (taking into account all extensions properly obtained) (x) all Tax Returns required to be filed with respect to the Companies for taxable years or periods of the Companies ending on or prior to the Closing Date (including, for the avoidance of doubt, the federal income Tax Returns filed for the consolidated group of which Owens Corning is the common parent for the tax period that includes the Closing Date) and (y) to the extent not described in clause (x), all Tax Returns required to be filed with respect to the Companies and due on or before the Closing Date, and in each case the Selling Stockholders shall remit, or cause to be remitted, any Taxes due in respect of such Tax Returns, and each Buyer shall timely file or cause to be timely filed when due (taking into account all extensions properly obtained) all other Tax Returns that are required to be filed by or with respect to the Companies, and each Buyer shall remit, or cause to be remitted, any Taxes due in respect of such Tax Returns. With respect to Tax Returns to be filed pursuant to the preceding sentence (I) such Tax Returns shall be filed in a manner consistent with past practice and no position shall be taken, election made or method adopted that is inconsistent with positions taken, elections made or methods used in prior periods in filing such Tax Returns (including any such position, election or method which would have the effect of accelerating income to periods for which the Selling Stockholders are liable or deferring deductions to periods for which the Buyers are liable) and (II) in the case of Tax Returns to be completed by the Buyers, such Tax Returns shall be submitted to the Selling Stockholders not later than 30 days prior to the due date for filing such Tax Returns (or, if such due date is within 45 days following the Closing Date, as promptly as practicable following the Closing Date) for review and approval by the Selling Stockholders, which approval may not be unreasonably withheld, but may in all cases be withheld if such Tax Returns were not prepared in accordance with clause (I) of this sentence. The Selling Stockholders or the Buyers shall pay the other party for the Taxes for which the Selling Stockholders or the Buyers, respectively, are liable pursuant to Section 8.1(a) but which are payable with any Tax Return to be filed by the other party pursuant to this Section 8.1(b) upon the written request of the party entitled to payment, setting forth in detail the computation of the amount owed by the Selling Stockholders or the Buyers, as the case may be, but in no event earlier than 10 business days prior to the due date for paying such Taxes, without regard to the aggregate indemnification limitations set forth in Section 11.1(a) and Section 11.2(a).

(ii) The Selling Stockholders shall terminate or cause to be terminated any and all of the tax sharing, allocation, indemnification or similar agreements, arrangements or undertakings in effect, written or unwritten, on the Closing Date as between either Selling Stockholder or any predecessor or affiliate thereof, on the one hand, and the Companies, on the other hand, for all Taxes imposed by any government or taxing authority, regardless of the period in which such Taxes are imposed, and there shall be no continuing obligation to make any payments under any such agreements, arrangements or undertakings.

(iii) None of the Buyers or any Affiliate of the Buyers shall (or shall cause or permit the Companies to) amend, refile or otherwise modify (or grant an extension of any statute of limitation or normal reassessment period with respect to) any Tax Return relating in whole or in part to the Companies with respect to any taxable year or period ending on or before the Closing Date (or with respect to any Straddle Period) without the prior written consent of the Selling Stockholders, which consent may be withheld in the sole discretion of the Selling Stockholders.

(iv) The Buyers shall promptly cause each of the Companies to prepare and provide to the Selling Stockholders a package of Tax information materials, including schedules and work papers (the “Tax Package”), required by the Selling Stockholders to enable the Selling Stockholders to prepare and file all Tax Returns required to be prepared and filed by it pursuant to Section 8.1(b)(i). The Tax Package shall be completed in accordance with past practice, including past practice as to providing such information and as to the method of computation of separate taxable income or other relevant measure of income of the Companies. The Buyers shall cause the Tax Package to be delivered to the Selling Stockholders as soon as practicable after the Closing Date.

(c) Contest Provisions. (i) The Buyers shall promptly notify the Selling Stockholders in writing upon receipt by the Buyers, any of their Affiliates or the Companies of notice of any pending or threatened federal, state, provincial, local, municipal or foreign Tax audits, examinations or assessments relating to taxable periods ending on or before the Closing Date or which might otherwise affect the Tax liabilities for which the Selling Stockholders may be liable pursuant to this Section 8.1.

(ii) The Selling Stockholders shall have the sole right to represent the Companies’ interests in any Tax audit or administrative or court proceeding relating to taxable periods ending on or before the Closing Date, and to employ counsel of their choice at their expense. In the case of a Straddle Period, the Selling Stockholders shall be entitled to participate at their expense in any Tax audit or administrative or court proceeding relating (in whole or in part) to Taxes attributable to the portion of such Straddle Period ending on and including the Closing Date and, with the written consent of the Buyers, and at the Selling Stockholders’ sole expense, may assume the entire control of such audit or proceeding. None of the Buyers, any of their Affiliates or the Companies may settle any Tax claim for any Taxes for which the Selling Stockholders may be liable pursuant to Section 8.1(a), without the prior written consent of the Selling Stockholders, which consent may be withheld in the sole discretion of the Selling Stockholders.

(d) Assistance and Cooperation. After the Closing Date, the Selling Stockholders and the Buyers shall (and shall cause their respective Affiliates to):

(i) assist the other parties in preparing any Tax Returns which such other party is responsible for preparing and filing in accordance with Section 8.1(b);

(ii) cooperate fully in preparing for any audits of, or disputes with taxing authorities regarding, any Tax Returns of the Companies;

(iii) make available to the others and to any taxing authority as reasonably requested all information, records, and documents relating to Taxes of the Companies;

(iv) provide timely notice to the others in writing of any pending or threatened Tax audits or assessments of the Companies for taxable periods for which the other may have a liability under this Section 8.1;

(v) furnish the others with copies of all correspondence received from any taxing authority in connection with any Tax audit or information request with respect to any such taxable period;

(vi) timely sign and deliver such certificates or forms as may be necessary or appropriate to establish an exemption from (or otherwise reduce), or file Tax Returns or other reports with respect to, Taxes described in Section 8.1(a)(v) (relating to sales, transfer and similar Taxes); and

(vii) timely provide to the others powers of attorney or similar authorizations necessary to carry out the purposes of this Section 8.1.

(e) Elections Under Section 338(h)(10). (i) Owens Corning shall make, or cause to be made, a joint election with SG for Norandex under Section 338(h)(10) of the Code and under any applicable similar provisions of state law with respect to the purchase of the stock of Norandex, and SG shall within 10 days after the completion of the Allocation Schedule described in Section 8.1(e)(ii), but in no event later than five days prior to the due date for filing Internal Revenue Service Form 8023, exchange completed and executed copies of Internal Revenue Service Form 8023, required schedules thereto (including Internal Revenue Service Form 8883), and any similar state forms. If any changes are required in these forms as a result of information which is first available after these forms are prepared, the parties will promptly agree on such changes.

(ii) Within 60 days following the final determination of the Working Capital Adjustment Amount pursuant to Section 4.8, Owens Corning shall prepare and deliver to SG a schedule (the “Allocation Schedule”) allocating the Aggregate Deemed Sales Price, as defined in Treasury Regulation Section 1.338-4, among the assets of Norandex. The Allocation Schedule shall be reasonable and shall be prepared in accordance with Section 338(h)(10) of the Code and the Treasury Regulations thereunder. The Allocation Schedule shall be deemed to be accepted by and shall be conclusive and binding on SG except to the extent, if any, that SG or SG’s accountant shall have delivered within 30 days after the date on which the Allocation Schedule is delivered to SG, a written notice to Owens Corning stating each and every item to which SG takes exception (it being understood that any amounts not disputed shall be final and binding). If a change proposed by SG is disputed by Owens Corning, then Owens Corning and SG shall negotiate in good faith to resolve such dispute. If, after a period of 20 days following the date on which SG gives Owens Corning notice of any such proposed change, any such proposed change still remains disputed, then SG and Owens Corning shall together choose an Accounting Firm to resolve any remaining disputes. The Accounting Firm shall act as an arbitrator to determine, based solely on presentations by SG and Owens Corning, and not by independent review, only those issues still in dispute with respect to the Allocation Schedule. The decision of the Accounting Firm shall be final and binding. All of the fees and expenses of the Accounting Firm shall be equally paid by SG, on the one hand, and Owens Corning, on the other hand. SG and Owens Corning each agree that promptly upon receiving the final and binding Allocation Schedule it shall return an executed copy thereof to the other party. Each of SG and Owens Corning agrees to file all federal, state, local and foreign Tax Returns in accordance with the Allocation Schedule.

(f) Survival and Coordination with Article XI. The representations, warranties and covenants in this Section 8.1 and Section 5.7 shall survive for the applicable statute of limitations or normal reassessment period. For the avoidance of doubt, the provisions of Sections 11.4, 11.5, and 11.6 of this Agreement shall apply to the matters covered by this Section 8.1, except to the extent of any inconsistency between those sections and this Section 8.1, in which case the provisions of Section 8.1 shall control.

Section 8.2 Employee Matters.

(a) Continued Employment. For the period commencing on the Closing Date and ending on the first anniversary of the Closing Date, the Buyers shall take any action necessary so that all individuals who are employees of the Companies (including employees who are not actively at work on account of illness, short-term disability or leave of absence) on the Closing Date (the “Affected Employees”) shall continue to receive base wages and salaries at rates no less favorable to such employee than the rates of wages and salaries paid by the Companies to such Affected Employees on, and to be employed at the same location as such Affected Employees were on, the date of this Agreement. This Section 8.2 does not in any way prohibit the Buyers or their Affiliates from terminating the employment of any Affected Employee following the Closing Date.

(b) Collective Bargaining. With respect to Affected Employees represented by a union or labor organization for purposes of collective bargaining, the Buyers shall ensure that such unions or labor organizations continue to be recognized as the bargaining representative of such Affected Employees as of the Closing Date. The Buyers shall assume the Companies’ obligations with respect to the collective bargaining agreements in effect on the Closing Date and adhere to the terms thereof, provided, however, for the avoidance of doubt, that the Buyers assume only the collective bargaining agreements set forth in Schedule 5.18. Prior to the Closing Date, the Selling Stockholders shall cause the Companies to timely provide any notice of the transactions contemplated by this Agreement required as may be required by law or collective bargaining agreement, and will satisfy any bargaining obligations related to the transactions contemplated by this Agreement.

(c) Buyers’ Benefit Plans. The Buyers and the Selling Stockholders shall jointly give notice to all employees of the Companies on the Closing Date that the active participation of Affected Employees in the Seller Plans shall terminate on the Closing Date, as of which date the Affected Employees shall be eligible to participate in the Buyers’ Pension Plans and Welfare Plans and other employee benefits (the “Buyers’ Benefit Programs”), subject to the terms and conditions of Buyers’ Benefit Programs. In no event shall any employee of the Companies be entitled to accrue any benefits under the Seller Plans with respect to services rendered or compensation paid after the Closing Date. For a period of one year beginning on and immediately following the Closing Date or such other period as required by applicable Requirements of Law or collective bargaining agreement, the Affected Employees shall receive employee benefits (including, for the avoidance of doubt, retirement, bonus, welfare and fringe benefits, but excluding emergence-related equity-based compensation and retiree medical benefits) under Buyers’ Benefit Programs that are no less favorable in the aggregate than those benefits provided under the Plans in effect immediately prior to the Closing Date as listed on Schedule 5.16(a) and (b).

(d) Severance Benefits. Notwithstanding any of the foregoing to the contrary, for the period commencing on the Closing Date and ending on the first anniversary of the Closing Date, the Buyers agree to, or to cause their Affiliates to, provide notice of termination or pay in lieu thereof, any severance benefits to any Affected Employee who is terminated following the Closing Date in an amount that is at least equal to the notice, or pay in lieu thereof, and termination benefits that would have been paid to such employee if he were terminated immediately prior to the Closing Date. The Companies shall have no obligation or liability to pay or provide any payments with respect to any Affected Employees for whom severance or termination obligations are incurred prior to the Closing Date.

(e) Welfare Benefits. Except as otherwise expressly provided herein, the Selling Stockholders or one of their Affiliates shall retain responsibility under the Plans that are Welfare Plans in which the Affected Employees participate with respect to all amounts that are payable by reason of, or in connection with, any and all welfare benefits provided to the Affected Employees and their eligible dependents but only to the extent that the services for such benefits were incurred prior to the Closing Date and claimed in compliance with the Welfare Plan terms. The Buyers and their Affiliates shall be responsible for all other welfare benefits provided to the Affected Employees and their eligible dependents to the extent that the services for such benefits were incurred on or after the Closing Date and claimed in compliance with Buyers’ Welfare Plan terms. The Buyers shall not assume assets or liabilities under any Welfare Plans sponsored or maintained by the Selling Stockholders or their Affiliates (other than the Companies), including, but not limited to, retiree medical obligations to current or former employees of the Companies under such plans.

(f) Credit for Service. To the extent that service is relevant for purposes of eligibility and vesting (and, in order to calculate the amount of any vacation, sick days, severance and similar benefits but not for purposes of pension benefit accruals), except as necessary to comply with Requirements of Law applicable to any Foreign Plan under Buyers’ Benefit Programs on and after the Closing Date, such Buyers’ Benefit Programs shall credit the Affected Employees for service earned on and prior to the Closing Date with any of the Companies, their subsidiaries, any of their Affiliates or any of their respective predecessors, to the extent it was recognized under a similar Seller Plan prior to the Closing Date, in addition to service earned with the Buyers or any of the Buyers’ Affiliates after the Closing Date.

(g) Preexisting Conditions; Coordination. Following the Closing Date, the Buyers shall, or shall cause their Affiliates to, waive limitations on eligibility, enrollment and benefits under the Buyers’ Benefit Programs which are Welfare Plans relating to any preexisting medical conditions of the Affected Employees and their eligible dependents. Following the Closing Date, for the plan year in which the Closing Date occurs, the Buyers shall recognize, or shall cause their Affiliates to also recognize, for purposes of annual deductible and out of pocket limits under the Buyers’ Benefit Programs which are Welfare Plans, deductible and out of pocket expenses paid by Affected Employees and their respective dependents under the Seller Plans which are Welfare Plans. The Selling Stockholders shall cause their insurance carrier to provide the Buyers (or at the direction of the Buyers, Buyers’ insurance carriers) with information, in form and substance reasonably satisfactory to the Buyers, on the deductibles and out-of-pocket expenses paid by Affected Employees and their respective dependents under the Seller Plans which are Welfare Plans subsequent to December 31, 2006 and up to the Closing Date. The Selling Stockholders shall pay any fees and expenses incurred by the Companies or the Selling Stockholders in obtaining such information.

(h) Vacations. The Buyers shall, or shall cause their Affiliates to, continue a vacation program for the benefit of the Affected Employees through at least the end of the calendar year in which the Closing occurs that is at least as favorable as the vacation program of the Companies in effect immediately prior to the Closing Date. The Buyers shall, or shall cause their Affiliates to, recognize and provide all accrued but unused vacation of each Affected Employee under such vacation program as of the Closing Date. The Selling Stockholders shall have no obligation or liability to pay or provide any vacation payments claimed on or after the Closing Date.

(i) Bonuses. The Buyers shall, or shall cause their Affiliates to, assume, maintain and honor all bonus programs which are designated “Company Plans” set forth on Schedule 5.16(b) for Affected Employees in existence as of the Closing Date and shall pay to the Affected Employees the bonuses that they earn under such programs for the full applicable period of time used to determine the Affected Employees’ bonuses in which the Closing Date occurs; provided, however, that with respect to the Siding Solutions Business Corporate Incentive Plan (the “SSBCIP”) only, the Selling Stockholders shall make pro rata payments of any bonuses accrued under the SSBCIP as of the Closing Date, in accordance with the terms and conditions of the SSBCIP, no later than 60 days following the Closing Date, and the Buyers shall adopt a bonus program similar to the SSBCIP which covers at least the Affected Employees who participated in the SSBCIP as of the Closing Date and which provides such Affected Employees with bonus opportunities, for the period beginning on the Closing Date and ending December 31, 2007, which are no less generous than as provided under the SSBCIP from January 1, 2007 through the Closing Date. The Selling Stockholders shall pay to each Affected Employee amounts under any bonus program that is not a Company Plan, which are accrued but not yet paid as of the Closing Date, at the time and in accordance with the terms of such programs.

(j) COBRA. Following the Closing Date, the Buyers shall, or shall cause an Affiliate to, provide continuation health care coverage to all Affected Employees and their qualified beneficiaries who have a “qualifying event” at any time on or after the Closing Date, in accordance with the continuation health care coverage requirements of Section 4980B of the Code (“COBRA”). The Selling Stockholders or one of their Affiliates shall provide COBRA coverage for former employees of the Companies who do not become Affected Employees or, for former employees who are not subject to COBRA, such other extended coverage as may be required by relevant legislation.

(k) WARN Act. The Selling Stockholders shall be responsible for all liabilities or obligations under The Worker Adjustment and Retraining Notification Act (“WARN Act”) and similar state and local rules, statutes and ordinances with respect to any employment loss occurring prior to the Closing Date affecting any employees of the Companies. The Buyers or their Affiliates shall be responsible for all liabilities or obligations under the WARN Act and similar state and local rules, statutes and ordinances resulting from any employment loss occurring on or after the Closing Date affecting any Affected Employees.

(l) Third-Party Claims. Regardless of anything else contained herein, the parties hereto do not intend for this Agreement to amend any Plans or arrangements or create any rights or obligations except between the parties to this Agreement. No Affected Employee or other current or former employee of the Companies or their Affiliates including any beneficiary or dependent thereof, or any other person not a party to this Agreement, shall be entitled to assert any claim hereunder.

(m) Workers’ Compensation. The Selling Stockholders shall be liable for any workers’ compensation or similar workers’ protection claims of any Affected Employee incurred prior to the Closing Date. The Companies shall be liable for any workers’ compensation, workplace safety and insurance or similar workers’ protection claims of any Affected Employee incurred on or after the Closing Date. For purposes of this paragraph, a claim is deemed incurred when the incident giving rise to a claim occurred, provided, however, that if more than one incident gave rise to a claim, the claim shall be deemed incurred as determined by applicable state workers’ compensation laws.

(n) Plan Asset Transfers; Vesting. Subject to the following sentence, no assets or liabilities shall be transferred from any Seller Plan to any plan or arrangement established by the Buyers. The Selling Stockholders shall, and shall cause their Affiliates to, take all actions necessary to permit each Affected Employee to effect a “direct rollover” (within the meaning of Section 402(f)(2)(A) of the Code) of his or her account balances under the Owens Corning Savings Plan or Owens Corning Savings and Security Plan, if such rollover is elected in accordance with the procedures established by the Selling Stockholders, to a defined contribution plan of the Buyers or an Affiliate thereof that includes a qualified cash or deferred arrangement within the meaning of Section 401(k) of the Code (the “Buyer 401(k) Plan”), including a direct rollover of any notes evidencing loans made to such Affected Employee. The Buyers agree to cause the Buyer 401(k) Plan to accept a direct rollover, including a direct rollover of any notes evidencing loans made to such Affected Employee to the Buyer 401(k) Plan of such Affected Employee’s account balances, including any outstanding loan balances, if such rollover is elected in accordance with the Requirements of Law. The Selling Stockholders shall cause the accrued benefits of all Affected Employees under the Owens Corning Cash Balance Pension Plan to be fully vested as of the Closing Date.

Section 8.3 Securities Law Legends. The Buyers agree and understand that the Shares have not been, and will not be, registered under the Securities Act or the securities laws of any state or to securities laws of any province or territory of Canada (collectively, “Securities Laws”) and that the Shares may be sold or disposed of only in one or more transactions registered under the Securities Act and applicable Securities Laws or as to which an exemption from the registration requirements of the Securities Act and applicable Securities Laws is available. The Buyers acknowledge and agree that no person has any right to require any of the Companies or the Selling Stockholders to cause the registration of any of the Shares. The certificates representing the Shares shall contain a legend similar to the following and other legends necessary or appropriate under applicable Securities Laws:

THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE “ACT”) OR ANY STATE SECURITIES LAWS AND MAY NOT BE SOLD, TRANSFERRED OR

OTHERWISE DISPOSED OF UNLESS A REGISTRATION STATEMENT UNDER THE ACT AND ANY APPLICABLE STATE SECURITIES LAWS WITH RESPECT TO SUCH SHARES IS EFFECTIVE OR UNLESS THE COMPANY IS IN RECEIPT OF AN OPINION OF COUNSEL SATISFACTORY TO IT TO THE EFFECT THAT SUCH SHARES MAY BE SOLD WITHOUT REGISTRATION UNDER THE ACT AND SUCH LAWS.

Section 8.4 Insurance; Risk of Loss. The Selling Stockholders shall cause the Companies to keep insurance policies currently maintained by the Companies covering the Business, assets and current or former employees, as the case may be, or suitable replacements therefor, in full force and effect through the close of business on the Closing Date. From and after the Closing Date, the Buyers shall be solely responsible for all insurance coverage and related risk of loss based on claims pending as of the Closing Date and claims made after the Closing Date, without regard to when the event giving rise to any such claim occurred, with respect to the Companies and their business, assets and current or former employees. To the extent that after the Closing any party hereto requires any information regarding claim data, payroll or other information in order to make filing with insurance carriers or self insurance regulators from another party hereto, such party will promptly supply such information.

Section 8.5 Indemnification, Directors’ and Officers’ Insurance.

(a) For six years from and after the Closing Date, the Buyers shall cause the Companies to indemnify and hold harmless all past and present officers and directors of the Companies to the same extent such Persons are indemnified as of the date of this Agreement by the Companies pursuant to the Charters of the Companies (to the fullest extent permitted by applicable law) for acts or omissions occurring at or prior to the Closing Date, and shall advance expenses reasonably incurred by each such person in connection with defending any claim, action or investigation arising out of such acts or omissions (including the reasonable costs of any investigation and preparation in connection therewith), to the fullest extent permitted by applicable law. To the extent permitted by applicable law, the Buyers shall provide such indemnification in the event it cannot be or is not provided by the Companies.

(b) If the Companies or any of their successors or assigns (i) shall consolidate with or merge into any other corporation or entity and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) shall transfer all or substantially all of their properties and assets to any individual, corporation or other entity, then, and in each such case, proper provisions shall be made so that the successors and assigns of the Companies shall assume all of the obligations set forth in this Section 8.5.

(c) The provisions of this Section 8.5 are intended to be for the benefit of, and shall be enforceable by, each of the past and present officers and directors of the Companies, their heirs, their representatives and assigns.

Section 8.6 Intentionally Omitted

Section 8.7 Use of Names. (a) The Selling Stockholders are not conveying ownership rights or granting the Buyers or their Affiliates (including the Companies after the

Closing) a license to use any of the tradenames, service marks or trademarks of the Selling Stockholders or any Affiliate of the Selling Stockholders (other than the trademarks and service marks included in the Intellectual Property identified in Schedule 5.11(a)(i)) (collectively, the “Retained Names and Marks”) and, after the Closing, subject to Section 8.7(d), the Buyers and their Affiliates (including the Companies after the Closing) shall not use in any manner the names or marks of the Selling Stockholders or any Affiliate of the Selling Stockholders or any word that is confusingly similar in sound or appearance to such names or marks, except as provided in this Section 8.7. In the event the Buyers or any Affiliate of the Buyers (including the Companies after the Closing) violate any of their obligations under this Section 8.7, the Selling Stockholders and their Affiliates may proceed against it in law or in equity for such damages or other relief as a court may deem appropriate. The Buyers acknowledge that a violation of this Section 8.7 may cause the Selling Stockholders and their Affiliates irreparable harm which may not be adequately compensated for by money damages. The Buyers therefore agree that in the event of any actual or threatened violation of this Section 8.7, the Selling Stockholders and their Affiliates shall be entitled, in addition to other remedies that they may have, to a temporary restraining order and to preliminary and final injunctive relief against a Buyer or such Affiliate of a Buyer to prevent any violations of this Section 8.7, without the necessity of posting a bond.

The failure to so notify the Indemnitor shall not relieve the Indemnitor of its obligations hereunder, except to the extent such failure shall have materially and adversely prejudiced the Indemnitor.

Section 11.4 Determination of Amount.

(a) In calculating any Loss or Expense there shall be deducted any insurance recovery in respect thereof (and no right of subrogation shall accrue hereunder to any insurer) which is actually received under any insurance policies in effect immediately prior to the Closing.

(b) For purposes of determining the amount of any Loss or Expense under Section 8.1 or this Article XI resulting from any inaccuracy in or a breach of a representation or warranty or a breach of a covenant or agreement hereunder (but not for purposes of determining whether there has been any inaccuracy in or a breach of a representation or warranty or a breach of a covenant or agreement), all references to any materiality, “Material Adverse Effect” or similar qualification (including specified dollar thresholds) shall be deemed to be deleted therefrom.

(c) After the giving of any Claim Notice pursuant to Section 11.3, the amount of indemnification to which an Indemnified Party shall be entitled under this Article XI shall be determined: (i) by the written agreement between the Indemnified Party and the Indemnitor; (ii) by a final judgment or decree of any court of competent jurisdiction; or (iii) by any other means to which the Indemnified Party and the Indemnitor shall agree. The judgment or decree of a court shall be deemed final when the time for appeal, if any, shall have expired and no appeal shall have been taken or when all appeals taken shall have been finally determined. The Indemnified Party shall have the burden of proof in establishing the amount of Losses and Expenses suffered by it.

Section 11.5 Third Person Claims.

(a) Any party seeking indemnification provided for under this Agreement in respect of, arising out of or involving a claim or demand made by any third Person against the Indemnified Party shall notify the Indemnitor in writing, and in reasonable detail, of the third Person claim within 10 days after receipt by such Indemnified Party of written notice of the third Person claim. Thereafter, the Indemnified Party shall deliver to the Indemnitor, within five business days after the Indemnified Party’s receipt thereof, copies of all notices and documents (including court papers) received by the Indemnitor relating to the third Person claim. Notwithstanding the foregoing, should a party be physically served with a complaint with regard to a third Person claim, the Indemnified Party shall notify the Indemnitor with a copy of the complaint within five business days after receipt thereof and shall deliver to the Indemnitor within seven business days after the receipt of such complaint copies of notices and documents (including court papers) received by the Indemnified Party relating to the third Person claim. The failure to give notice as provided in this Section 11.5 shall not relieve the Indemnitor of its obligations hereunder except to the extent it shall have been prejudiced by such failure.

(b) If any action, lawsuit or other legal proceeding shall be threatened or instituted or any claim or demand shall be asserted by any Person in respect of which payment may be sought by one party hereto from the other party under the provisions of this Article XI, the Indemnified Party shall promptly cause written notice of the assertion of any such claim of which it has knowledge which is covered by this indemnity to be forwarded to the Indemnitor. Any notice of a claim by reason of any of the representations, warranties or covenants contained in this Agreement shall refer to the provision of this Agreement or any other agreement, document or instrument executed hereunder or in connection herewith upon which such claim is based and, to the extent known, describe in reasonable detail the facts giving rise to an alleged basis for the claim and the amount of the liability asserted against the Indemnitor by reason of the claim. In the event of the initiation of any action, claim, lawsuit or other legal proceeding against the Indemnified Party by a third Person, the Indemnitor shall have the sole and absolute right after the receipt of notice, at its option (which must be exercised in writing within 30 days following receipt of such notice) and at its own expense, to be represented by counsel of its choice and to control, defend against, negotiate, settle or otherwise deal with such third Person claim to the extent indemnified against hereunder; provided, however, that the Indemnified Party may participate in any such proceeding with counsel of its choice and at its expense; provided, further, that if the Indemnified Party has been advised by its outside counsel that there may exist a conflict of interest that would make it inappropriate for the same counsel to represent both the Indemnitor and the Indemnified Party, then any such expenses shall be promptly paid or

reimbursed by the Indemnitor. Prior to assuming control of the defense of any third Person claim pursuant to the preceding sentence, the Indemnitor must acknowledge in writing that it has an indemnity obligation for any Losses or Expenses resulting from such third Person claim, subject to the applicable limitations set forth in this Article XI. Notwithstanding anything herein to the contrary, the Indemnitor shall not be entitled to assume or maintain control of the defense of any third Person claim, shall not be entitled to settle or compromise any such claim, and shall pay the reasonable fees and expenses of counsel retained by the Indemnified Party, if (A) the third Person claim relates to or arises in connection with any criminal proceeding, action, indictment, allegation or investigation, (B) the third Person claim seeks injunctive or equitable relief against the Indemnified Party or (C) the Indemnitor has not elected to defend or is failing to defend in good faith the third Person claim. Each of the parties hereto agrees to, and to cause its Affiliates to, cooperate fully with the other parties in connection with the defense, negotiation or settlement of any such action, claim, lawsuit or other legal proceeding, or demand and to make available to the other parties all witnesses, pertinent records, materials and information in such party’s possession or under such party’s control relating thereto as is reasonably required by the other parties. To the extent the Indemnitor elects not to defend such third Person claim, and the Indemnified Party defends against or otherwise deals with any such third Person claim, the Indemnified Party may retain counsel, at the expense of the Indemnitor, and control the defense of such proceeding; provided, however, that the Indemnitor shall be obligated pursuant to this Section 11.5 to pay for only one firm of counsel for all Indemnified Parties. Neither the Indemnitor nor the Indemnified Party may settle any such proceeding which settlement obligates the other party to pay money, to perform obligations or to admit liability without the consent of the other party, such consent not to be unreasonably withheld. In the event the Indemnified Party shall refuse to consent to the settlement of any third Person claim, so long as (x) only money damages are involved; (y) there is no admission of liability or wrongdoing with respect to the Indemnified Party and (z) such proposed settlement provides an unqualified release of the Indemnified Party from all liability in respect of such third Person claim, then, the liability of the Indemnitor in respect of such third Person claim shall not exceed the amount for which the third Person claim could have been settled plus the amount of expenses incurred by the Indemnified Party prior to the time of the proposed settlement to which it is entitled to indemnification. After any final judgment or award shall have been rendered by a court, arbitration board or administrative agency of competent jurisdiction and the time in which to appeal therefrom has expired, or a settlement shall have been consummated, or the Indemnified Party and the Indemnitor shall arrive at a mutually binding agreement with respect to each separate matter alleged to be indemnified by the Indemnitor hereunder, the Indemnified Party shall forward to the Indemnitor notice of any sums due and owing by it with respect to such matter and the Indemnitor shall pay all of the sums so owing to the Indemnified Party by wire transfer, certified or bank cashier’s check within 15 days after the date of such notice.

(c) To the extent of any inconsistency between this Section 11.5 and Section 8.1(c) (relating to Tax contests), the provisions of Section 8.1(c) shall control with respect to Tax contests.

(a) In any case where an Indemnified Party recovers from third Persons any amount in respect of a matter with respect to which an Indemnitor has indemnified it pursuant to

this Article XI, such Indemnified Party shall promptly pay over to the Indemnitor the amount so recovered (after deducting therefrom the full amount of the expenses incurred by it in procuring such recovery), but not in excess of the sum of (i) any amount previously so paid by the Indemnitor to or on behalf of the Indemnified Party in respect of such matter and (ii) any amount expended by the Indemnitor in pursuing or defending any claim arising out of such matter.

(c) Neither the representations, warranties and covenants of the Selling Stockholders nor the Buyers’ rights to indemnification with respect thereto shall be affected or deemed waived by reason of any investigation made by or on behalf of the Buyers (including by any of their advisors, consultants or representatives) or by reason of the fact that any of the Buyers or any of such advisors, consultants or representatives knew or should have known that any such representation or warranty is, was or might be inaccurate or by reason of the Buyers’ waiver of any condition set forth in Article IX.

(f) The Buyers and the Selling Stockholders agree that any indemnification payment made pursuant to this Article XI shall be treated as an adjustment to the Purchase Price for all Tax purposes.

Section 13.6 Entire Agreement; Amendments. This Agreement, the Exhibits and Schedules referred to herein, the documents delivered pursuant hereto, the letter agreement of even date herewith between Owens Corning and SG regarding an executive of the Business, and the Confidentiality Agreement contain the entire understanding of the parties hereto with regard to the subject matter contained herein or therein, and supersede all other prior representations, warranties, agreements, understandings or letters of intent between or among any of the parties hereto. This Agreement shall not be amended, modified or supplemented except by a written instrument signed by an authorized representative of each of the parties hereto.

Section 13.7 Interpretation. Disclosure of any fact or item in any Schedule hereto referenced by a particular section in this Agreement shall be deemed to have been disclosed with respect to every other section in this Agreement to which it relates so long as its relevance to such other schedule or section is readily apparent on the face of the information disclosed. Neither the specification of any dollar amount in any representation or warranty contained in this Agreement nor the inclusion of any specific item in any Schedule hereto is intended to imply that such amount, or higher or lower amounts, or the item so included or other items, are or are not

material, and no party shall use the fact of the setting forth of any such amount or the inclusion of any such item in any dispute or controversy between the parties as to whether any obligation, item or matter not described herein or included in any Schedule is or is not material for purposes of this Agreement. Unless this Agreement specifically provides otherwise, neither the specification of any item or matter in any representation or warranty contained in this Agreement nor the inclusion of any specific item in any Schedule hereto is intended to imply that such item or matter, or other items or matters, are or are not in the ordinary course of business, and no party shall use the fact of the setting forth or the inclusion of any such item or matter in any dispute or controversy between the parties as to whether any obligation, item or matter not described herein or included in any Schedule is or is not in the ordinary course of business for purposes of this Agreement.

If the Closing occurs, any supplement, amendment or addition approved by the Buyers pursuant to the preceding sentence will be effective to cure and correct for all other purposes any breach of any representation, warranty or covenant which would have existed if the Companies or the Selling Stockholders had not made such supplement, amendment or addition, and all references to any Schedule hereto which is supplemented or amended as provided in this Section 13.7 shall for all purposes after the Closing be deemed to be a reference to such Schedule as so supplemented or amended.

Section 13.8 Waivers. Any term or provision of this Agreement may be waived, or the time for its performance may be extended, by the party or parties entitled to the benefit thereof. Any such waiver shall be validly and sufficiently authorized for the purposes of this Agreement if, as to any party, it is authorized in writing by an authorized representative of such party. The failure of any party hereto to enforce at any time any provision of this Agreement shall not be construed to be a waiver of such provision, nor in any way to affect the validity of this Agreement or any part hereof or the right of any party thereafter to enforce each and every such provision. No waiver of any breach of this Agreement shall be held to constitute a waiver of any other or subsequent breach.

Section 13.9 Expenses. Except as expressly set forth herein, (i) each party hereto will pay all costs and expenses incident to its negotiation and preparation of this Agreement and to its performance and compliance with all agreements and conditions contained herein on its part to be performed or complied with, including the fees, expenses and disbursements of its counsel and independent public accountants; provided, however, that, the Selling Stockholders shall pay all fees and expenses incurred by the Companies in connection with the transactions contemplated hereby, including, without limitation, the fees and expenses related to the engagement of UBS Securities LLC and (ii) subject to Section 8.2(i), the Selling Stockholders shall be solely responsible for any payment (including, without limitation, any bonus and incentive compensation, severance, forgiveness of indebtedness or golden parachute payment) made to the Affected Employees, or to officers or directors of the Companies, in connection with the execution of this Agreement or the consummation of the transactions contemplated herein.
