		Press Release
		FOR IMMEDIATE RELEASE

DOMTAR TO CREATE LARGEST FINE PAPER COMPANY IN NORTH AMERICA THROUGH COMBINATION WITH WEYERHAEUSER’S FINE PAPER BUSINESS

	•		Enterprise value of new company to exceed US$6 billion

	•		The “new Domtar” to be led by Domtar’s current President and CEO, Raymond Royer

	•		Head Office in Montréal, Quebec; Headquarters of Operations in Fort Mill, South Carolina

Montreal, August 23, 2006 — Domtar Inc. (TSX/NYSE: DTC) today announced the creation of the largest manufacturer and marketer of uncoated freesheet paper in North America and the second largest in the world. Domtar has signed a definitive agreement to combine with Weyerhaeuser’s (NYSE: WY) fine paper business and related assets. The new company, to be called Domtar, will have its Head Office in Montréal, Quebec, while the Headquarters of Operations will be in Fort Mill, South Carolina. The transaction has been approved by the Boards of Directors of both companies.

“With this transaction, we are transforming Domtar into one of the world’s leading paper companies, presenting shareholders with new opportunities and creating a stronger company for employees and customers,” said Raymond Royer, Domtar’s President and Chief Executive Officer, who will lead the new company in the same capacity. “We are proactively enhancing the quality of our asset mix and taking decisive action to assure our future in a consolidating industry. In addition to more than doubling Domtar’s current paper production capacity, this compelling strategic and operational fit will make the new company financially stronger with prominent brands, a lower cost base and the necessary scale and scope to succeed in the highly competitive global marketplace”, added Mr. Royer.

Based on annualized Q2 2006 unaudited results for Domtar (excluding Norampac) and for Weyerhaeuser’s fine paper business, Domtar estimates the new company would generate approximately US$6.5 billion in sales and US$730 million in EBITDA, before synergies. The new company will have an enterprise value exceeding US$6 billion.

The “New Domtar”

The backbone of the new company will be six highly efficient world-class uncoated freesheet mills that will provide two-thirds of its more than five million tons of capacity. These mills, combined with a solid mix of specialty facilities, will make the new company one of the most efficient and cost-competitive paper companies in North America. The company will have an expanded North American reach and a wide range of well-known business and commercial

printing paper brands. With greater access to volume, increased depth of product offerings, and better service through a wider geographic footprint, the company will be in a position to meet the needs of large and small customers alike throughout Canada and the United States. It will maintain the environmental leadership shown by both Domtar and Weyerhaeuser, notably through added capacity to expand its environmentally and socially responsible papers such as the EarthChoice® product line. (For more details on the new company see the “Fact Sheet” issued with this news release.)

Leadership Team

Mr. Royer, as President and CEO, will lead an organization of nearly 14,000 employees with a management team composed of executives from Domtar and Weyerhaeuser paper operations. This team includes Marvin Cooper, currently Weyerhaeuser’s Senior Vice-President, Cellulose Fiber & White Paper, Containerboard Manufacturing and Engineering, who will become Chief Operating Officer of the new company. Domtar’s current Senior Vice-President and Chief Financial Officer, Daniel Buron, will be the Chief Financial Officer.

Harold MacKay, counsel and former chairman and senior partner at the Regina, Canada-based law firm of MacPherson Leslie and Tyerman LLP, and an international advisor to Weyerhaeuser’s Board of Directors, will become non-executive Chairman of the new company’s 13-member Board of Directors — seven of whom will be nominated by Weyerhaeuser and six by Domtar. Mr. MacKay will resign his Weyerhaeuser advisory role before becoming Chairman of the “new Domtar”.

Synergies

It is anticipated that the new company will achieve approximately US$200 million in annualized synergies within two years, created by a combination of process optimization resulting in lower operating costs, reductions in transportation, logistics and purchasing costs, implementation of best-in-class business practices and sales and administrative cost reductions. The cost to implement these synergies is anticipated to be approximately US$100 million.

Transaction Structure

Under the terms of the transaction, which is structured as a “Reverse Morris Trust”, Weyerhaeuser’s fine paper business, consisting of 10 primary pulp and paper mills (seven in the United States and three in Canada), converting, forming and warehousing facilities and two sawmills will be transferred into a newly formed company for stock and a cash payment of US$1.35 billion to be provided by the new company through borrowings under a credit facility. Weyerhaeuser will distribute the shares of the new company to its shareholders in either a spin-off or split-off transaction at its own discretion. (A spin-off would provide a pro-

2 / 5

rata distribution of shares to Weyerhaeuser shareholders. A split-off would allow Weyerhaeuser shareholders the opportunity to exchange Weyerhaeuser shares for stock in the new paper business.) Domtar will combine with the newly formed company to create the “new Domtar”.

The combination will take place under a Plan of Arrangement. Under the Plan of Arrangement:

	1.		All shares of Domtar will be automatically exchanged — on a one-for-one basis — for common shares of a Canadian subsidiary of the “new Domtar”.

	2.		Following that, Domtar shareholders who are taxable Canadian residents can either exchange these shares for common shares in the “new Domtar” (which will be traded on the New York Stock Exchange and on the Toronto Stock Exchange) or they can receive the “new Domtar” Canadian subsidiary exchangeable shares (which will be traded on the Toronto Stock Exchange). The exchangeable shares are the economic equivalent of the common shares of the “new Domtar”, with equal dividend entitlement and voting rights at the level of the “new Domtar”. The exchangeable shares are exchangeable at any time at the option of the holder into the “new Domtar” common shares on a one-for-one basis.

	3.		For taxable Canadian residents who choose the exchangeable shares, the transaction will be tax deferred. However, if they select to receive shares directly in the “new Domtar”, the transaction is taxable.

	4.		Non-Canadian residents who are Domtar shareholders will automatically receive common shares in the “new Domtar” and for them the transaction will be taxable.

	5.		The transaction is expected to be tax deferred to all U.S. holders of Weyerhaeuser shares.

At the time of the closing, the combined company will be owned approximately 55% by former Weyerhaeuser shareholders and 45% by former Domtar shareholders.

The combination is subject to approvals by the shareholders of Domtar by a special resolution, the Superior Court of Quebec, appropriate regulatory and other authorities, as well as customary closing conditions. The transaction is expected to close in the first quarter of 2007. Domtar and Weyerhaeuser will continue to operate separately until the transaction closes.

Applications will be made to list the shares of the “new Domtar” on the New York Stock Exchange and on the Toronto Stock Exchange, and the exchangeable shares on the Toronto Stock Exchange.

In due course, information relating to this transaction, including Domtar’s Management Proxy Circular in connection with the anticipated Special Meeting of Domtar shareholders to be convened to consider the transaction, will be prepared and distributed to holders of Domtar’s common and preferred shares. Special Meeting and record dates will be announced later.

Domtar’s financial advisors in this transaction are J.P. Morgan Securities Inc. and RBC Dominion Securities Inc., and its legal advisers are Debevoise & Plimpton LLP and Ogilvy Renault LLP.

		POUR DIFFUSION IMMÉDIATE

DOMTAR CRÉE LA PLUS GRANDE SOCIÉTÉ DE PAPIERS FINS D’AMÉRIQUE DU NORD PAR UN REGROUPEMENT AVEC LE SECTEUR DES PAPIERS FINS DE WEYERHAEUSER

	•		La valeur d’entreprise de la nouvelle société sera de plus de 6 milliards $US

	•		Le « nouveau Domtar » sera dirigé par Raymond Royer, président et chef de la direction actuel de Domtar

	•		Le siège social sera situé à Montréal, Québec, et le siège de l’exploitation sera à Fort Mill, Caroline du Sud

Montréal, le 23 août 2006 — Domtar inc. (TSX/NYSE : DTC) a annoncé aujourd’hui la création de la plus importante entreprise de fabrication et de mise en marché de papiers non couchés d’Amérique du Nord et la seconde dans le monde. Domtar a signé un accord définitif de regroupement avec le secteur des papiers fins de Weyerhaeuser (NYSE : WY) et ses actifs associés. La nouvelle entreprise sera connue sous le nom de Domtar et aura son siège social à Montréal, Québec, tandis que le siège de l’exploitation sera à Fort Mill, Caroline du Sud. La transaction a été approuvée par les conseils d’administration des deux sociétés.

« Cette transaction va transformer Domtar en l’une des plus grandes sociétés de papier au monde, présentant aux actionnaires de nouvelles occasions et renforçant la société au bénéfice de nos employés et de nos clients », a déclaré Raymond Royer, président et chef de la direction de Domtar, qui assumera les mêmes fonctions au sein de la nouvelle entreprise. « Nous améliorons proactivement la qualité de notre bassin d’actifs et posons des gestes significatifs pour garantir notre avenir dans un secteur en consolidation. Outre le fait que nous allons plus que doubler la capacité de production actuelle de papier de Domtar, ce mariage stratégique et opérationnel probant va renforcer la position financière de la nouvelle société qui profitera de marques réputées, d’une réduction de ses coûts de base, ainsi que de l’envergure et de la portée nécessaires pour connaître du succès dans un marché international hautement concurrentiel », a ajouté M. Royer.

Selon les résultats annualisés non vérifiés du deuxième trimestre de 2006 de Domtar (excluant Norampac) ainsi que du secteur des papiers fins de Weyerhaeuser, Domtar estime que la nouvelle société générerait environ 6,5 milliards $US en ventes et 730 millions $US en bénéfices avant intérêts, impôts, dépréciation et amortissement (BAIIA), avant les synergies. La valeur d’entreprise de la nouvelle société sera de plus de 6 milliards $US.

Le « nouveau Domtar »

L’assise de la nouvelle entreprise sera constituée de six usines de papiers non couchés sans pâte mécanique de classe internationale très efficaces qui produiront les deux tiers des plus de cinq millions de tonnes de papier que pourra fabriquer la société. Ces usines, jointes à une solide combinaison d’installations spécialisées, feront de la nouvelle société l’une des entreprises de papier

1 / 5

les plus efficaces et les plus concurrentielles d’Amérique du Nord. La société aura un rayonnement élargi en Amérique du Nord et une gamme étendue de marques renommées de papier d’affaires et d’impression commerciale. Avec un accès à des volumes de production accrus, une gamme enrichie de produits et un meilleur service grâce à une implantation géographique élargie, la société sera à même de répondre aux besoins de ses clients, petits et grands, à travers le Canada et les États-Unis. La société maintiendra le leadership environnemental dont font preuve Domtar et Weyerhaeuser, notamment grâce à sa capacité accrue d’élargir sa gamme de papiers éthiques et écologiques comme EarthChoiceMC. (Pour en savoir plus sur la nouvelle société, veuillez consulter la fiche d’information émise avec le présent communiqué de presse.)

L’équipe de direction

M. Royer, en tant que président et chef de la direction, dirigera une société de près de 14 000 employés qui comptera une équipe de direction composée de cadres supérieurs de Domtar et des opérations de papier de Weyerhaeuser. Cette équipe inclura notamment Marvin Cooper, premier vice-président actuel de Weyerhaeuser, Cellulose Fiber & White Paper, Containerboard Manufacturing and Engineering, qui sera chef de l’exploitation de la nouvelle société. M. Daniel Buron, premier vice-président et chef des finances actuel de Domtar, en deviendra le chef des finances.

Harold MacKay, avocat-conseil, ancien président et associé principal de MacPherson Leslie et Tyerman LLP, un cabinet d’avocats de Régina, et conseiller international auprès du conseil d’administration de Weyerhaeuser, sera président non-exécutif du conseil d’administration de 13 membres de la nouvelle société, dont sept seront nommés par Weyerhaeuser et six par Domtar. M. MacKay démissionnera de son rôle de conseiller auprès de Weyerhaeuser avant de devenir président du « nouveau Domtar ».

Synergies

On estime que la nouvelle société réalisera environ 200 millions $US de synergies annualisées d’ici deux ans, générées par une optimisation des procédés entraînant une baisse des coûts d’exploitation, une réduction des frais de transport, de logistique et d’achats, la mise en œuvre des meilleures pratiques d’affaires de leur catégorie ainsi que des réductions des frais de vente et d’administration. Le coût de mise en œuvre de ces synergies devrait être d’environ 100 millions $US.

Structure de la transaction

Aux termes de la transaction, structurée en tant que « Morris Trust inversé », le secteur des papiers fins de Weyerhaeuser, constitué de 10 usines de pâte et papier de premier ordre (sept aux États-Unis et trois au Canada), d’installations de conversion, de formation et d’entreposage et de deux scieries, sera transféré à une société nouvellement formée contre des actions et un paiement en espèces de 1,35 milliard $US qui seront avancés par la nouvelle société par le biais d’emprunts de facilité de crédit. Weyerhaeuser distribuera les actions de la nouvelle société à ses actionnaires dans une transaction de cession-distribution ou de scission-échange, à sa convenance. (Une cession-

2 / 5

distribution fournirait une distribution proportionnelle d’actions aux actionnaires de Weyerhaeuser. Une scission-échange permettrait aux actionnaires de Weyerhaeuser d’échanger des actions Weyerhaeuser pour des titres dans la nouvelle société de papier.) Domtar et cette société nouvellement formée se regrouperont pour créer le « nouveau Domtar ».

Le regroupement se fera conformément à un plan d’arrangement. En vertu du plan d’arrangement :

	1.		Toutes les actions de Domtar seront automatiquement échangées — sur une base d’une action pour une action — pour les actions ordinaires d’une filiale canadienne du « nouveau Domtar ».

	2.		Ensuite, les actionnaires de Domtar qui sont résidents canadiens imposables pourront échanger ces actions pour une action dans le « nouveau Domtar » (qui sera coté à la bourse de New York et à la bourse de Toronto) ou recevoir des actions échangeables du « nouveau Domtar » (qui sera coté à la bourse de Toronto). Les actions échangeables sont l’équivalent économique des actions ordinaires du « nouveau Domtar ». Les actions échangeables sont échangeables en tout temps au choix du porteur au profit d’actions ordinaires du « nouveau Domtar » sur une base d’une action pour une action.

	3.		Pour les résidents canadiens imposables qui choisissent les actions échangeables, la transaction fera l’objet d’une imposition différée. Toutefois, s’ils décident de choisir directement des actions du « nouveau Domtar », la transaction sera imposable.

	4.		Les résidents non-canadiens qui sont des actionnaires de Domtar recevront automatiquement des actions du « nouveau Domtar » et, pour eux, la transaction sera imposable.

	5.		La transaction devrait faire l’objet d’une imposition différée pour tous les détenteurs américains d’actions Weyerhaeuser.

A la clôture, la société combinée sera détenue à environ 55 % par d’anciens actionnaires de Weyerhaeuser et à 45 % par d’anciens actionnaires de Domtar.

Le regroupement est soumis à l’approbation des actionnaires de Domtar par l’adoption d’une résolution spéciale, de la Cour supérieure du Québec, des autorités réglementaires et autres autorités pertinentes, ainsi qu’aux conditions habituelles de clôture. La clôture de la transaction devrait avoir lieu au premier trimestre 2007. Domtar et Weyerhaeuser continueront à exercer leurs activités séparément jusqu’à la clôture de la transaction.

Une demande sera faite d’inscrire les actions du « nouveau Domtar » à la bourse de New York et à la bourse de Toronto, et les actions échangeables à la bourse de Toronto.

Les informations relatives à cette transaction, y compris la circulaire de sollicitation de procuration de Domtar relative à la réunion spéciale anticipée des actionnaires de Domtar, convoquée pour examiner la transaction, seront éventuellement préparées et distribuées aux détenteurs d’actions ordinaires et privilégiées de Domtar. Les dates de la réunion spéciale et de l’enregistrement seront annoncées plus tard.

Avertissement concernant les énoncés prospectifs et les états financiers non vérifiés

Les informations financières contenues dans le présent communiqué et reflétant le regroupement de Domtar et du secteur des papiers fins de Weyerhaeuser et ses actifs associés sont basées sur des états financiers « segmentés » non vérifiés du secteur des papiers fins de Weyerhaeuser et ses actifs associés, car, historiquement, des états financiers n’ont pas été préparés pour le secteur des papiers fins de Weyerhaeuser et de ses actifs associés. Ces états financiers « segmentés » sont dérivés des registres comptables historiques de Weyerhaeuser. Les résultats d’exploitation et les flux de trésorerie historiques du secteur des papiers fins de Weyerhaeuser et ses actifs associés risquent de ne pas être indicatifs de ce qu’ils auraient été si un tel volet d’entreprise avait été une entité autonome, ni nécessairement indicatifs de ce que les résultats d’exploitation et les flux de trésorerie futurs d’une telle entreprise pourront être dans l’avenir. Les états financiers vérifiés du secteur des papiers fins de Weyerhaeuser et ses actifs associés pour les exercices clos les 31 décembre 2005, 2004 et 2003 seront fournis et inclus dans la circulaire de sollicitation de procuration qui sera distribuée aux actionnaires de Domtar mentionnés ci-dessus. Des écarts pourront exister entre ces états financiers vérifiés et les états financiers non vérifiés sur lesquels la direction et le conseil d’administration de Domtar se sont fiés pour approuver cette transaction.

Le communiqué de presse peut comporter des énoncés de nature prospective liés aux tendances ou représentant les opinions de la direction sur la croissance future de Domtar et du « nouveau Domtar », les résultats des exploitations, la performance ainsi que les perspectives et les occasions d’affaires. Ces énoncés se caractérisent en général par l’utilisation de termes comme « prévoir », « croire », « prédire », « entendre », « viser », « envisager », « planifier », « continuer », « estimer », « pouvoir », « devoir » et des expressions similaires et incluent, sans limitation aucune, des énoncés concernant les bénéfices, économies et synergies anticipées résultant du regroupement de Domtar et du secteur des papiers fins de Weyerhaeuser et ses actifs associés, y compris les résultats financiers et les résultats d’exploitation futurs, les plans, objectifs, attentes et intentions du « nouveau Domtar », les marchés pour les produits du « nouveau Domtar », le développement des affaires du « nouveau

Domtar » dans l’avenir, et les éventualités et l’incertitude auxquelles le « nouveau Domtar » pourra être assujetti et d’autres énoncés qui ne constituent pas des faits historiques. Ces énoncés reflètent les opinions de la direction et se fondent sur des informations auxquelles la direction a accès actuellement. Les énoncés de nature prospective sont nécessairement fondés sur diverses estimations ou hypothèses qui, bien que considérées comme raisonnables par la direction, sont essentiellement soumises à certains risques et incertitudes connus et inconnus tels que, sans toutefois s’y limiter, les conditions d’affaires et économiques générales, les prix de vente des produits, les coûts des matières premières et les charges d’exploitation, l’évolution des taux de change, la capacité d’intégrer les exploitations acquises aux exploitations actuelles, l’aptitude à réaliser les économies de coûts prévues, la performance des établissements de fabrication et d’autres facteurs cités dans le présent document de même que dans les documents que Domtar dépose dans le cadre du processus d’information continue. Il faut considérer ces facteurs avec prudence et ne pas accorder une confiance excessive aux énoncés de nature prospective. Bien que les énoncés de nature prospective se fondent sur des estimations et des hypothèses que la direction croit raisonnables, Domtar ne peut assurer que les résultats réels ne différeront pas sensiblement de ceux décrits ou sous-entendus dans ces énoncés. À moins d’y être tenu selon les lois, ni Domtar, ni Weyerhaeuser, ni le « nouveau Domtar » n’assume l’obligation de mettre à jour ou de réviser ces énoncés de nature prospective de manière à refléter de nouveaux événements ou des circonstances nouvelles. Les risques, incertitudes et autres facteurs comprennent, entre autres, ceux dont il est question sous la rubrique « Risques et incertitudes » dans le document « Commentaires et analyse par la direction » de Domtar, pour l’exercice financier terminé le 31 décembre 2005, et sous la rubrique « Risques et incertitudes » du document « Commentaires et analyse par la direction » du deuxième trimestre de 2006 de Domtar de même que les risques de réalisation des synergies anticipées et de l’intégration des activités et des actifs des deux parties. Il n’est aucunement garanti que la transaction envisagée dans ce communiqué sera complétée, ou qu’elle le sera selon les conditions générales décrites dans ce communiqué.

(c) upon the transfer of Class B Common Shares by the holder thereof as set forth in Section 1.04(b), the name of such holder will be removed from the register of holders of Class B Common Shares and added to the register of holders of Spinco Common Stock or Exchangeable Shares, as the case may be, and (i) in the case of the Spinco Elected Shares, Newco Canada will be recorded as the registered holder of such Class B Common Shares so exchanged and will be deemed to be the legal and beneficial owner thereof and (ii) in the case of the Exchangeable Elected Shares, the Class B Common Shares transferred to Newco Canada Exchangeco will be canceled by Newco Canada Exchangeco;

Newco Canada Exchangeco will not be responsible for any taxes, interest or penalties resulting from the failure by a holder of Class B Common Shares to properly complete or file the election forms in the form and manner and within the time prescribed by the ITA (or any applicable provincial legislation);

(h) each outstanding award of restricted Domtar Common Shares (“Domtar Restricted Shares”) granted pursuant to the Domtar Restricted Stock Plan shall be exchanged for Class B Common Shares, in accordance with Section 1.04(a), which in turn will be exchanged for restricted shares of Spinco Common Stock or restricted Exchangeable Shares in accordance with Sections 1.04(b), 1.04(c) and 1.04(d), as applicable (“Replacement Restricted Shares”), and the Replacement Restricted Shares shall be subject to the same terms and conditions as were applicable to the Domtar Restricted Shares;

(b) All Domtar U.S. Pension Plans intended to be tax qualified have been the subject of determination letters from the IRS, with respect to all tax Law changes with respect to which the IRS is currently willing to provide a determination letter to the effect that such Domtar U.S. Pension Plans are qualified and exempt from Federal income taxes under Sections 401(a) and 501(a), respectively, of the Code, and no such determination letter has been revoked nor, to the knowledge of Domtar, has revocation been threatened, nor has any such Domtar U.S. Pension Plan been amended since the date of its most recent determination letter or application therefor in any respect that would reasonably be expected to adversely affect its qualification or materially increase its costs (other than any amendment to permit Newco Employees (as defined in Section 4.10) to participate in such plan) or require “security” within the meaning of Section 307 of ERISA. Each Domtar Canadian Pension Plan (other than any Domtar Canadian MEPP) has been established and registered in accordance with the applicable requirements of the ITA and applicable pension standards legislation and such registration has not been revoked nor, to the knowledge of Domtar, has revocation been threatened by the Canadian tax authorities or the applicable pension regulatory authorities.

(c) No Domtar U.S. Pension Plan, other than any Domtar U.S. Pension Plan that is a “multiemployer plan” within the meaning of Section 4001(a)(3) of ERISA (an “Domtar Multiemployer Pension Plan”), had, as of the respective last annual valuation date for each such Domtar U.S. Pension Plan, an “unfunded benefit liability” (as such term is defined in Section 4001(a)(18) of ERISA), based on actuarial assumptions that have been furnished to Weyerhaeuser and Spinco, except for instances which, either individually or in the aggregate, have not had and would not reasonably be expected to have a Domtar Material Adverse Effect. None of the Domtar U.S. Pension Plans has an “accumulated funding deficiency” (as such term is defined in Section 302 of ERISA or Section 412 of the Code), whether or not waived, except for instances which, either individually or in the aggregate, have not had and would not reasonably be expected to have a Domtar Material Adverse Effect. Each Domtar Canadian Pension Plan is fully funded on a going concern and solvency basis pursuant to the actuarial assumptions and methodologies set out in Section 3.11(c) of the Domtar Disclosure Letter. None of Domtar or any Domtar Subsidiary, and, to the knowledge of Domtar, no Domtar Employee and no trustee, fiduciary or administrator of any Domtar Benefit Plan or trust thereunder, has

engaged in a “prohibited transaction” (as such term is defined in Section 406 of ERISA or Section 4975 of the Code) or any other breach of fiduciary responsibility that would reasonably be expected to subject Domtar, any Domtar Subsidiary or any Domtar Employee to the tax or penalty on prohibited transactions imposed by such Section 4975 or to any liability under Section 502(i) or 502(1) of ERISA, except to the extent that any such taxes or penalties, individually or in the aggregate, have not had and would not reasonably be expected to have a Domtar Material Adverse Effect. None of such Domtar Benefit Plans and trusts has been terminated, nor has there been any “reportable event” (as that term is defined in Section 4043 of ERISA) with respect to any Domtar Benefit Plan during the last five years, except to the extent that any such reportable events, individually or in the aggregate, have not had and would not reasonably be expected to have a Domtar Material Adverse Effect. Neither Domtar nor any Domtar Subsidiary has incurred a “complete withdrawal” or a “partial withdrawal” (as such terms are defined in Sections 4203 and 4205, respectively, of ERISA) since the effective date of such Sections 4203 and 4205 with respect to any Domtar Multiemployer Pension Plan. Neither Domtar nor any Domtar Subsidiary contributes to or has any liability under any multi-employer pension plan as defined under applicable Canadian federal or provincial pension standards legislation.

(d) No Domtar U.S. Welfare Benefit Plan is unfunded or funded through a “welfare benefits fund” (as such term is defined in Section 419(e) of the Code). Each Domtar U.S. Welfare Plan that is a “group health plan” (as such term is defined in Section 5000(b)(1) of the Code), complies with the applicable requirements of Section 4980B(f) of the Code. Each Domtar U.S. Welfare Plan and each Domtar Canadian Welfare Plan (in each case including any such plan covering retirees or other former employees) may be amended or terminated without material liability to Domtar and any Domtar Subsidiary on or at any time after the Effective Time. No Domtar U.S. Welfare Plan or Domtar Canadian Welfare Plan provides post-retirement health or life insurance benefits, except where the cost thereof is borne entirely by the former employee (or his or her eligible dependents).

(e) Neither Domtar nor any person or entity that would be treated as a single employer with Domtar for purposes of Section 414(b), (c), (m) or (o) of the Code would reasonably be expected to incur any Controlled Group Liability (as defined in this Section 3.11(e)) in an amount that would reasonably be expected to have a Domtar Material Adverse Effect. For purposes of this Agreement, “Controlled Group Liability” means any and all liabilities (i) under Title IV of ERISA, other than for payment of premiums to the Pension Benefit Guaranty Corporation (“PBGC”), (ii) under Section 302 or 4068(a) of ERISA, (iii) under Section 412(n) or 4971 of the Code, and (iv) for violation of the continuation coverage requirements of Section 601 et seq. of ERISA and Section 4980B of the Code or the group health requirements of Sections 9801 et seq. of the Code and Sections 701 et seq. of ERISA.

(f) Other than payments that may be made to the persons listed in Section 3.11(f) of the Domtar Disclosure Letter (the “Primary Domtar Executives”), no amount or other entitlement that could be received (whether in cash or property or the vesting of property) as a result of the Transaction by any officer, director, manager or employee of Domtar or any Domtar Subsidiary who is a “disqualified individual” (as such term is defined in Treasury Regulation Section 1.280G-1) under any Domtar Benefit Plan, Domtar Benefit Agreement or other compensation arrangement would be characterized as an “excess parachute payment” (as defined

in Section 280G(b)(1) of the Code) and no such disqualified individual is entitled to receive any additional payment (including, without limitation, any tax gross up or other payment) from Domtar, any Domtar Subsidiary or any other person in the event that the excise tax required by Section 4999(a) of the Code is imposed on such disqualified individual. Section 3.11(f) of the Domtar Disclosure Letter sets forth (i) the Company’s reasonable, good faith estimates of the maximum amount that could be paid to each Primary Domtar Executive as a result of the Transactions under any Domtar Benefit Plan, Domtar Benefit Agreement or other compensation arrangements and (ii) the “base amount” (as defined in Section 280G(b)(3) of the Code) for each Primary Domtar Executive calculated as of the date of this Agreement.

(g) The execution and delivery of each Transaction Document do not, and the consummation of the Transactions and compliance with the terms hereof and thereof will not (i) entitle any Domtar Employee to severance, termination, change in control or similar pay and benefits, (ii) accelerate the time of payment or vesting or trigger any payment or funding (through a grantor trust or otherwise) of compensation or benefits under, increase the amount payable or trigger any other material obligation pursuant to, any Domtar Benefit Plan or Domtar Benefit Agreement, or (iii) result in any breach or violation of, or a default under, any Domtar Benefit Plan or Domtar Benefit Agreement.

SECTION 3.12. Labor Matters. Except as set forth in Section 3.12 of the Domtar Disclosure Letter:

(a) There are no, and during the past three years there has not been any, strikes, lockouts, work stoppages, slowdowns or any other concerted interference with normal operations, stoppage or lockout pending or, to the knowledge of Domtar, threatened against or affecting any Domtar Employee, Domtar or any Domtar Subsidiary, except where such strikes, lockouts, work stoppages, slowdowns, or any other concerted interference with normal operations, stoppage or lockout, individually or in the aggregate, have not had and would not reasonably be expected to have a Domtar Material Adverse Effect.

Neither Domtar nor any Domtar Subsidiary has received any written communication during the past two years from a Governmental Entity that alleges that Domtar or any Domtar Subsidiary is not in compliance in any material respect with any applicable Law. This Section 3.14 does not relate to matters with respect to Taxes, which are the subject of Section 3.09, or Environmental Laws, which are the subject of Section 3.16.

SECTION 3.15. Brokers. No broker, investment banker, financial advisor or other person, other than JP Morgan and RBC Dominion Securities Inc. is entitled to any broker’s, finder’s, financial advisor’s or other similar fee or commission in connection with the Transactions based upon arrangements made by or on behalf of Domtar or any of its subsidiaries.

(a) any “material contract” (as defined in Item 601(b)(10) of Regulation S-K promulgated under the Securities Act) (the term “material contract” to be applied as if Newco were a separate company for purposes of this Section 4.20(a));

Each of the Newco Material Agreements required to be set forth in Section 4.20 of the Weyerhaeuser Disclosure Letter or entered into after the date of this Agreement is or will be in full force and effect (except to the extent any of them expires in accordance with its terms), and neither Weyerhaeuser nor any Weyerhaeuser Subsidiary has violated any provisions of, or committed or failed to perform any act that, with or without notice, lapse of time, or both, would constitute a default under the provisions of any Newco Material Agreement, except for violations or defaults that, individually or in the aggregate, have not had and would not reasonably be expected to have a Newco Material Adverse Effect. True, correct and complete copies of each written Newco Material Agreement (and a summary of each oral Newco Material Agreement) listed in Section 4.20 of the Weyerhaeuser Disclosure Letter (including all written modifications and amendments thereto and waivers thereunder) have been made available to Domtar.

SECTION 4.21. Affiliate Transactions. Section 4.21 of the Weyerhaeuser Disclosure Letter sets forth a list of all contracts, agreements, arrangements, commitments or understandings, whether or not entered into in the ordinary course of business, to or by which Weyerhaeuser or any Weyerhaeuser Subsidiary (other than the Spinco Parties), on the one hand, and any Spinco Party, on the other hand, are a party or are bound, and that are in effect on the date of this Agreement and shall, or are reasonably expected to, be in effect on or after the Effective Time other than this Agreement and the other Transaction Documents.

SECTION 4.22. Opinion of Weyerhaeuser Financial Advisor. Weyerhaeuser, as the sole stockholder of Spinco, has received the written opinion of Morgan Stanley & Co. Incorporated, to the effect that, as of the date of such opinion, the consideration to be received by the holders of Weyerhaeuser Common Stock pursuant to the Transactions is fair from a financial point of view to such holders. Weyerhaeuser has delivered a copy of such opinion to Domtar for informational purposes only.

(b) Section 4.23(b) of the Weyerhaeuser Disclosure Letter lists all real property (in each case, together with the address, if any) in which Newco or any of the Newco Subsidiaries will hold a leasehold interest following the Contribution and the other Transactions contemplated by this Agreement and that is material in the operation or conduct of the Newco Business (the “Newco Leased Real Property”). Weyerhaeuser has made available to Domtar a true and complete copy of each material lease agreement under which the Newco Leased Real Property is held. There is no material default under any such lease agreement by Weyerhaeuser or any Weyerhaeuser Subsidiary or, to the knowledge of Weyerhaeuser, by any other party thereto that has had or would reasonably be expected to have a Newco Material Adverse Effect.

SECTION 4.24. Sufficiency of Assets. At the Effective Time, the Newco Assets, taken together with the Newco Canada Exchangeco Assets and the services available from Weyerhaeuser or any Weyerhaeuser Subsidiary under the Transition Services Agreement, the intellectual property rights licensed under the Intellectual Property License Agreement and the goods and services provided under the Fiber Supply Agreements, the Site Services Agreements, the other Transaction Documents and the arrangements contemplated by Sections 2.09 and 2.10 of the Contribution and Distribution Agreement, will constitute those assets, services and intellectual property rights reasonably required to operate the Newco Business in all material respects as currently conducted and as proposed to be conducted in accordance with Section 5.01(b). Nothing in this Section 4.24 shall be construed to constitute a representation or warranty as to title to the Newco Assets, the Newco Exchangeco Assets or the Retained Licensed Intellectual Property licensed under the Intellectual Property License Agreement, which is the subject of Sections 4.17 and 4.18.

arising solely from the offer and conversion of the Exchangeable Shares and the issuance of the shares of Spinco Common Stock; and

(iii) the taking of all such action as may be required under the CBCA in connection with the transactions contemplated by this Agreement and the Plan of Arrangement.

(c) Weyerhaeuser, Spinco and Domtar shall each promptly notify the other if at any time before or after the Effective Time it becomes aware that the Domtar Circular, the Weyerhaeuser Canada Circular or an application for an order, filing or a registration statement described in Section 6.02 or 6.03 contains any untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements contained therein not misleading in light of the circumstances in which they are made, or that otherwise requires an amendment or supplement to the Domtar Circular, the Weyerhaeuser Canada Circular or such application, filing or registration statement. In any such event, the Spinco Parties and Domtar shall cooperate in the preparation of a supplement or amendment to the Domtar Circular, the Weyerhaeuser Canada Circular or such other document, as required and as the case may be, and, if required, shall cause the same to be distributed to shareholders of Weyerhaeuser or Domtar and/or filed with the relevant securities regulatory authorities.

SECTION 6.06. Access to Information; Confidentiality. Each of Weyerhaeuser, Newco and Domtar shall, and shall cause each of its respective subsidiaries to (in the case of Weyerhaeuser, with respect to the Newco Business only), afford to the other party and to the officers, employees, accountants, counsel, financial advisors and other representatives of such

other party, reasonable access during normal business hours during the period prior to the Effective Time to all their respective properties, plants, books, contracts, commitments, personnel and records and, during such period, each of Weyerhaeuser (with respect to the Newco Business only) and Domtar shall, and shall cause each of its respective subsidiaries to, furnish promptly to the other party (a) a copy of each report, schedule, registration statement and other document filed by it during such period pursuant to the requirements of Canadian Securities Legislation or of U.S. Federal or state securities laws and (b) to the extent permitted by Law, all other information concerning its business, properties and personnel as such other party may reasonably request; provided, however, that either party may withhold (i) any documents (or portions thereof) or information that is subject to the terms of a confidentiality agreement with a third party, (ii) any document (or portions thereof) or information which may constitute privileged attorney-client communications or attorney work product and the transfer of which, or the provision of access to which, as reasonably determined by such party’s counsel, constitutes a waiver of any such privilege, or (iii) any documents (or portions thereof) or information relating to pricing or other matters that are highly sensitive if the exchange of such documents (or portions thereof) or information, as determined by such party’s counsel, might reasonably result in antitrust difficulties for such party or any of its affiliates. If any material is withheld by such party pursuant to the proviso to the preceding sentence, such party shall inform the other party as to the general nature of what is being withheld. Upon its execution of a work paper access letter in customary form, each of Domtar and Weyerhaeuser shall be afforded reasonable access by the other party during normal business hours during the period prior to the Effective Time to all information used by such other party in the preparation of Audited Newco Financial Statements or, as applicable, the Audited Domtar Financial Statements (in the case of the Audited Newco Financial Statements, when such financial statements become available).

SECTION 6.07. Reasonable Best Efforts; Notification. (a) Upon the terms and subject to the conditions set forth in this Agreement, each of the parties hereto shall use its reasonable best efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other parties in doing, all things necessary, proper or advisable to consummate and make effective, in the most expeditious manner practicable, the Transactions, including (i) the obtaining of all necessary or advisable actions or non-actions, waivers, consents and approvals from Governmental Entities and the making of all necessary or advisable registrations and filings (including filings with Governmental Entities, if any) and the taking of all reasonable steps as may be necessary to obtain an approval or waiver from, or to avoid an action or proceeding by, any Governmental Entity, (ii) the obtaining of all necessary or advisable consents, approvals or waivers from third parties, (iii) the defending of any lawsuits or other legal proceedings, whether judicial or administrative, challenging this Agreement or any other Transaction Document or the consummation of the Transactions, including seeking to have any stay or temporary restraining order entered by any court or other Governmental Entity vacated or reversed and (iv) the execution and delivery of any additional instruments necessary to consummate the Transactions and to fully carry out the purposes of the Transaction Documents.

Domtar, Weyerhaeuser and the Spinco Parties shall not have any substantive contact with any Governmental Entity in respect of any filing or proceeding contemplated by this Section unless it consults with the other parties in advance and, to the extent permitted by such Governmental Entity, gives the other party or parties the opportunity to participate.

(e) Without limiting the generality of the first sentence of Section 6.07(a), each of Weyerhaeuser and Domtar shall use its reasonable best efforts to cooperate with Spinco and Newco in connection with the financing contemplated by the New Debt Commitment Letter, including using (and causing its subsidiaries to use) reasonable best efforts to satisfy all conditions precedent to be satisfied by the Spinco Parties in the New Debt Commitment Letter, providing information to and permitting the financing sources and their representatives access to the Newco Business and the Domtar Business, respectively, participating in meetings with prospective investors and participating (and permitting members of its senior management to participate) in bank meetings in connection with the financing, participating in meetings with rating agencies, participating in drafting sessions related to the offering materials for the debt financing contemplated by the New Debt Commitment Letter, causing the present and former independent accountants for Weyerhaeuser and Domtar, respectively, to participate in drafting sessions related to the offering materials for the debt financing contemplated by the New Debt Commitment Letter and making work papers available to the respective parties, the financing sources and their respective representatives.

SECTION 6.08. Weyerhaeuser Stock Options, Stock Appreciation Rights and Restricted Stock Units. (a) As soon as practicable following the date of this Agreement, the Board of Directors of Weyerhaeuser (or, if appropriate, any committee administering the Weyerhaeuser Stock Plans) and the Board of Directors of Spinco shall adopt such resolutions or take such other actions as may be required to effect the following:

(i) prior to the Contribution, each Newco Employee that holds a Weyerhaeuser equity award that is described in clauses (ii), (iii), (iv) or (v) below (each, a “Weyerhaeuser Equity Award”) shall be given the opportunity to elect, by a date prior to the Measurement Date as determined by Weyerhaeuser, to (A) continue to hold all of such Newco Employee’s Weyerhaeuser Equity Awards in accordance with their terms, or (B) surrender all of such Newco Employee’s Weyerhaeuser Equity Awards in exchange for substituted Spinco equity awards as set forth in clauses (ii), (iii), (iv) and (v) below (any Newco Employee who elects to surrender all of such Newco Employee’s Weyerhaeuser Equity Awards as set forth in this clause (B), a “Rollover Employee”);

(ii) immediately prior to the Distribution, each outstanding option to acquire shares of Weyerhaeuser Common Stock granted under the Weyerhaeuser Stock Plans held by a Rollover Employee (whether vested or unvested) (each, a “Weyerhaeuser Option”) shall be surrendered to Weyerhaeuser in exchange for an option granted by Spinco to acquire, on the

same terms and conditions as were applicable under the Weyerhaeuser Option, a number of shares of Spinco Common Stock (rounded down to the nearest whole share), determined by multiplying the number of shares of Weyerhaeuser Common Stock subject to such Weyerhaeuser Option by the Option Exchange Ratio (as defined in this Section 6.08(a)), at an exercise price per share of Spinco Common Stock (rounded up to the nearest whole cent) equal to (A) the per share exercise price for the shares of Weyerhaeuser Common Stock otherwise purchasable pursuant to such Weyerhaeuser Option divided by (B) the Option Exchange Ratio (each, as so granted, a “Substituted Spinco Option”);

(iii) any Weyerhaeuser Option that is intended to be an “incentive stock option” (as defined in Section 422 of the Code), that may not be exchanged in the manner described in clauses (i) and (ii) of this Section 6.08(a) and that remains an incentive stock option, shall be adjusted in accordance with the requirements of Section 424 of the Code in a manner that most closely produces the economic results obtained with respect to other Substituted Spinco Options (it being understood that it is the intention of the parties hereto that Substituted Spinco Options so granted by Spinco qualify, to the fullest extent permissible, as “incentive stock options” (as defined in Section 422 of the Code), to the extent that such Weyerhaeuser Options qualified as “incentive stock options” immediately prior to the Contribution);

(iv) immediately prior to the Distribution, each outstanding stock appreciation right with respect to Weyerhaeuser Common Stock granted under the Weyerhaeuser Stock Plans held by a Rollover Employee (whether vested or unvested) (each, a “Weyerhaeuser SAR”) shall be surrendered to Weyerhaeuser in exchange for a stock appreciation right granted by Spinco, on the same terms and conditions as were applicable under the Weyerhaeuser SAR, with respect to the number of shares of Spinco Common Stock (rounded down to the nearest whole share), determined by multiplying the number of shares of Weyerhaeuser Common Stock subject to such Weyerhaeuser SAR by the Option Exchange Ratio, at an appreciation base price per share of Spinco Common Stock (rounded up to the nearest whole cent) equal to (A) the per share appreciation base price for the shares of Weyerhaeuser Common Stock subject to such Weyerhaeuser SAR divided by (B) the Option Exchange Ratio (each, as so granted, a “Substituted Spinco SAR”); and

(v) immediately prior to the Distribution, each outstanding grant of restricted stock units with respect to Weyerhaeuser Common Stock granted under the Weyerhaeuser Stock Plans held by a Rollover Employee (each, a “Weyerhaeuser RSU”) shall be surrendered to Weyerhaeuser in exchange for a grant of restricted stock units by Spinco, on the same terms and conditions as were applicable under the Weyerhaeuser RSU, with respect to the number of shares of Spinco Common Stock (rounded down to the nearest whole share), determined by multiplying the number of shares of Weyerhaeuser Common Stock subject to such Weyerhaeuser RSU by the Option Exchange Ratio (each, as so granted, a “Substituted Spinco RSU”).

For purposes of this Section 6.08(a), the following definitions shall apply:

“Option Exchange Ratio” shall mean a fraction, the numerator of which is the Average Weyerhaeuser Pre-Distribution Price, and the denominator of which is the Average Spinco Distribution Price.

“Average Weyerhaeuser Pre-Distribution Price” shall mean the volume weighted average (rounded to the nearest 1/10,000) of the trading prices of the Weyerhaeuser Common Stock on the NYSE as reported by Bloomberg Financial Markets (or such other source as the parties shall agree in writing) for the last trading day immediately prior to (i) the date on which the Weyerhaeuser Common Stock begins to trade ex-dividend with respect to the Distribution (if the Distribution is effected in whole as a pro rata dividend) or (ii) the Distribution Date (if the Distribution is effected in whole or in part as an exchange offer).

“Average Spinco Distribution Price” shall mean the volume weighted average (rounded to the nearest 1/10,000) of the trading prices of the Domtar Common Shares on the NYSE as reported by Bloomberg Financial Markets (or such other source as the parties shall agree in writing) for the last trading day immediately prior to the Distribution Date.

(b) Subject to the adjustments required by Section 6.08(a) after giving effect to the Transactions, immediately following the Distribution, Spinco shall assume the Substituted Spinco Options, Substituted Spinco SARs and Substituted Spinco RSUs, with the result that all obligations of Spinco under the stock plans of Spinco (the “Spinco Stock Plans”) with respect to Substituted Spinco Options, Substituted Spinco SARs and Substituted Spinco RSUs outstanding immediately prior to the Distribution, shall be obligations of Spinco following the Distribution. Notwithstanding the foregoing, Spinco may grant the Substituted Spinco Options, Substituted Spinco SARs and Substituted Spinco RSUs under an existing or newly established equity incentive plan of Spinco.

(c) As soon as reasonably practicable after the Distribution, Spinco shall deliver to the holders of Substituted Spinco Options, Substituted Spinco SARs and Substituted Spinco RSUs appropriate notices setting forth such holders’ rights pursuant to the respective Weyerhaeuser Stock Plans and the agreements evidencing the grants of such Substituted Spinco Options, Substituted Spinco SARs and Substituted Spinco RSUs and that such Substituted Spinco Options, Substituted Spinco SARs and Substituted Spinco RSUs and agreements shall be granted by Spinco and shall continue in effect on the same terms and conditions (subject to the adjustments required by this Section 6.08 after giving effect to the Transactions.

(d) A holder of an Substituted Spinco Option or Substituted Spinco SAR may exercise such Substituted Spinco Option or Substituted Spinco SAR in whole or in part in accordance with its terms by delivering a properly executed notice of exercise to Spinco, together with the consideration therefor and any applicable Canadian or U.S. Federal withholding tax information required in accordance with the related Weyerhaeuser Stock Plan.

(e) For purposes of this Agreement, “Weyerhaeuser Stock Plans” means the Weyerhaeuser Company 2004 Long-Term Incentive Plan, the Weyerhaeuser Company 1998

Long-Term Incentive Compensation Plan and the Weyerhaeuser Company 1992 Long-Term Incentive Compensation Plan.

SECTION 6.09. New Benefit Plans. (a) General. (i) For purposes of this Agreement, the term “Transferred Employee” shall refer to each Newco Employee who, at the Effective Time, is employed with Newco or its subsidiaries (including any individuals who are not actively at work on the Distribution Date due to vacation, holiday, illness, jury duty, bereavement leave or other authorized leave of absence, including, subject to Section 6.09(a)(ii) short-term disability leave, long-term disability leave or, subject to Section 6.09(a)(iii), workers’ compensation). The parties hereto intend that Transferred Employees shall have continuous and uninterrupted employment immediately before and immediately after the Effective Time, and that for purposes of any severance or termination benefit plan, program, policy, agreement or arrangement of Weyerhaeuser, Spinco, Newco, Domtar or any of their respective subsidiaries or affiliates, the Transactions contemplated by the Transaction Documents shall not constitute a severance of employment of any Transferred Employee prior to or upon the consummation of the Transactions.

(ii) Newco Employees who are on short-term or long-term disability leave (“Disabled Newco Employees”) other than union employees at Dryden, Ontario; Ear Falls, Ontario; Big River, Saskatchewan; Prince Albert, Saskatchewan and Kamloops, British Columbia will not become Transferred Employees until such time, if any, as they are determined by the relevant insurer to be no longer eligible for benefits under the applicable Weyerhaeuser short-term or long-term disability plan and present themselves for re-employment, at which time any such employee shall be offered continuing employment, to the extent such employee is able to return to employment (including with any reasonable accommodation), with Newco on the terms and conditions generally applicable to Transferred Employees under this Section 6.09. Prior to such time, Weyerhaeuser shall retain all liability with respect to providing short-term and long-term disability benefits to Disabled Newco Employees to the extent the Disabled Newco Employees are eligible to receive such benefits. Disabled Newco Employees who are union employees at Dryden, Ontario; Ear Falls, Ontario; Big River, Saskatchewan; Prince Albert, Saskatchewan and Kamloops, British Columbia will become Transferred Employees pursuant to the Canadian Purchase Agreement but continue to receive short-term and long-term disability benefits under Weyerhaeuser benefit plans for so long as they are eligible to receive such benefits under such plans, provided that, Newco fully and promptly reimburses Weyerhaeuser for all costs incurred in allowing for such continued participation in such Weyerhaeuser benefit plans and that Newco makes all reasonable efforts, including accommodation, to allow such employees to return to active employment.

(iii) With respect to each of the functions set forth on Schedule 2.11(a)(v) to the Contribution and Distribution Agreement, Weyerhaeuser shall confer with Domtar in good faith to identify and determine the approach to filling full time equivalent positions (including new hires) with respect to Weyerhaeuser employees who are not exclusively engaged in the Newco Business but are currently performing the functions set forth on such Schedule 2.11(a)(v) so that sufficient employees (both as to number and expertise) shall be (i) transferred from Weyerhaeuser to Newco or hired by Newco to enable Newco to operate the Newco Business from and after the Effective Time in substantially the same manner that it was operated prior to the Effective Time after giving effect to the services provided under the Transition Services

Agreement and the Site Services Agreements, and (ii) retained by Weyerhaeuser to enable Weyerhaeuser to operate the Weyerhaeuser Business from and after the Effective Time in the same manner that such business was operated prior to the Effective Time. During the period commencing on the 90th day prior to the day on which the parties anticipate the Effective Time will occur and ending on the Closing Date, Domtar shall be permitted to make presentations to and meet with (A) the Newco Employees set forth in Schedule 2.11(a)(i) to the Contribution and Distribution Agreement, (B) the Mill Employees other than those set forth on Schedule 2.11(a)(ii) to the Contribution and Distribution Agreement, (C) each Newco Employee set forth on Schedule 2.11(a)(iii) to the Contribution and Distribution Agreement, (D) the Forest Management Employees set forth in Schedule 2.11(a)(iv) to the Contribution and Distribution Agreement, and (E) the Newco Employees identified pursuant to the previous sentence with respect to the functions set forth on Schedule 2.11(a)(v) to the Contribution and Distribution Agreement, in each case either individually or in groups and upon reasonable advance notice to Weyerhaeuser. Weyerhaeuser shall permit such Newco Employees to attend such meetings and Domtar shall cooperate with Weyerhaeuser to minimize any disruption or interference to any business operations of Weyerhaeuser or its affiliates in the scheduling, location or other conduct of any such meetings. On or about the 30th day prior to the day on which the parties anticipate the Effective Time will occur, Weyerhaeuser shall update Schedules 2.11(a) and 2.11(d) to the Contribution and Distribution Agreement with information regarding which Newco Employees listed thereon (i) have accepted offers of employment by a Spinco Party, (ii) have refused an offer of employment by any Spinco Party, (iii) whose employment by Weyerhaeuser, Spinco or any affiliate of Weyerhaeuser or Spinco has terminated for any reason, or (iv) are on short-term or long-term disability leave or other leave of absence. The parties agree that (i) no Newco Employee shall be required to relocate from his or her primary office location in connection with the transfer of his or her employment to any Spinco Party, (ii) no employee (other than the new hires referenced in the first sentence of this Section 6.09(a)(iii)) who is not engaged in the Newco Business will be a Transferred Employee, and (iii) for the period commencing on the date of this Agreement and ending on the Closing Date, no Newco Employee who is expected to become a Transferred Employee (other than any Newco Employee who refuses an offer of employment from a Spinco Party notwithstanding Weyerhaeuser’s good faith compliance with this Section 6.09(a) and Section 2.11(a) of the Contribution and Distribution Agreement) will be offered employment with Weyerhaeuser or any of its affiliates other than a Spinco Party. Newco Employees employed in the United States who are absent from work and receiving workers compensation benefits related to such absence (“U.S. WC Newco Employees”) will not become Transferred Employees until such time, if any, as they are determined by the relevant insurer to be able to return to employment and present themselves for re-employment, at which time any such employee shall be offered continuing employment, to the extent such employee is able to return to employment, with Newco on the terms and conditions generally applicable to Transferred Employees under this Section 6.09. Prior to such time, Weyerhaeuser shall retain all liability with respect to providing workers compensation benefits to U.S. WC Newco Employees to the extent the U.S. WC Newco Employees are eligible to receive such benefits.

(b) Prior Service Credit. From and after the Effective Time, Newco shall give or cause Newco to give each Transferred Employee full credit for all purposes (including for purposes of eligibility to participate, early retirement eligibility and early retirement subsidies, vesting and, except with respect to defined benefit pension plans, benefit accrual) under any employee benefit plans and arrangements provided, maintained or contributed to by Newco or

any Newco Subsidiary (other than the Assumed Canadian Plans), for such Transferred Employee’s service with Weyerhaeuser and its subsidiaries, and with any predecessor employer, to the same extent recognized by Weyerhaeuser and its subsidiaries and affiliates immediately prior to the Effective Time.

(c) Establishment of New Benefit Plans. Effective as of the Effective Time, each Transferred Employee shall cease to participate in any employee benefit plan, arrangement or understanding (other than the Assumed Canadian Plans) that is maintained or sponsored by Weyerhaeuser or any of its affiliates (other than Spinco, Newco or any Newco Subsidiary) (other than as a former employee of Weyerhaeuser or any of its affiliates to the extent, if any, permitted by the terms of such employee benefit plan, arrangement or understanding). Effective immediately following the Effective Time, Spinco shall establish, or cause Newco to establish, compensation and benefit plans, programs and arrangements for the benefit of the Transferred Employees (collectively, “New Benefit Plans”) that provide benefits that are substantially as favorable in the aggregate as such plans, programs and arrangements that were in effect for the benefit of the Transferred Employees immediately prior to the Effective Time, provided that the arrangements set forth in Section 6.09(c) of the Weyerhaeuser Disclosure Letter shall be implemented by Newco promptly following to the Effective Time. From and after the Effective Time, Spinco shall, or shall cause its subsidiaries (including Newco and Domtar) to, honor the liabilities, obligations and commitments under the Domtar Benefit Plans and the Domtar Benefit Agreements with respect to the Domtar Employees.

(d) Annual Bonus for Year of Transactions. Spinco shall, or shall cause its subsidiaries (including Newco and Domtar) to, (i) assume all liabilities, obligations and commitments with respect to the Transferred Employees under the applicable annual incentive plan or arrangement of Weyerhaeuser and its subsidiaries other than such liabilities, obligations and commitments arising out of services performed by the Transferred Employees during fiscal year 2006 and honor the liabilities, obligations and commitments with respect to the Domtar Employees under the applicable annual incentive plan or arrangement of Domtar and its subsidiaries that relate to any periods commencing prior to and ending after the Effective Time, (ii) maintain such applicable plan or arrangement pursuant to its terms as in effect as of the Effective Time for such Transferred Employees and Domtar Employees, subject to any modifications that are required in order to take into account the impact, if any, of the Transactions contemplated by the Transaction Documents on the performance measures set forth in such applicable plan or arrangement, with respect to all performance periods thereunder commencing prior to and ending after the Effective Time, and (iii) at the times prescribed by such applicable plan or arrangement as in effect as of the Effective Time, make payments to the Transferred Employees and the Domtar Employees in accordance with the terms of such applicable plan or arrangement as in effect as of the Effective Time.

(e) Certain Welfare Benefits Matters. (i) With respect to each New Benefit Plan that is an “employee welfare benefit plan” within the meaning of Section 3(1) of ERISA or an employee health or welfare plan which provides benefits to Canadian employees (collectively, (“New Welfare Plans”), Spinco shall, or shall cause Newco to, (A) waive all limitations as to pre-existing conditions, exclusions and waiting periods and actively-at-work requirements with respect to participation and coverage requirements applicable to the Transferred Employees and their dependents and beneficiaries under the New Welfare Plans to the extent waived under the

applicable corresponding Newco Benefit Plan immediately prior to the Effective Time and (B) provide each Transferred Employee and his or her eligible dependents and beneficiaries with credit under New Welfare Plans for any co-payments and deductibles paid under corresponding Newco Benefit Plans prior to the Effective Time in the calendar year in which the Effective Time occurs for purposes of satisfying any applicable deductible or out-of-pocket requirements (and any annual and lifetime maximums) under any New Welfare Plans in which the Transferred Employees participate. Spinco shall also (A) honor, and cause Domtar to continue to honor, the participation elections of each Domtar Employee with respect to each Domtar U.S. Welfare Plan and Domtar Canadian Welfare Plan as in effect as of the Effective Time and (B) if any Domtar Employee becomes a participant in a New Welfare Plan or other welfare plan sponsored or maintained by Newco or any of its affiliates (other than a Domtar U.S. Welfare Plan or Domtar Canadian Welfare Plan) during the 12-month period following the Effective Time, (i) waive all limitations as to preexisting conditions, exclusions and waiting periods and actively-at-work requirements with respect to participation and coverage requirements applicable to participants and their dependents and beneficiaries under such plan to the extent waived under the applicable corresponding Domtar U.S. Welfare Plan or Domtar Canadian Welfare Plan and (ii) provide such Domtar Employee and his or her eligible dependents and beneficiaries with credit under such plan for any co-payments and deductibles paid under the corresponding Domtar Benefit Plan in the calendar year in which such Domtar Employee becomes a participant in such plan for purposes of satisfying any applicable deductible or out-of-pocket requirements (and any annual and lifetime maximums) under such plan.

(ii) Effective as of the Effective Time, Spinco shall, or shall cause Newco to, assume all obligations, liabilities and commitments of Weyerhaeuser and its subsidiaries to Transferred Employees and their eligible dependents in respect of health insurance under the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”), the Health Insurance Portability and Accountability Act of 1996 (“HIPAA”), Sections 601 et seq. and Sections 701 et seq. of ERISA, Section 4980B and Sections 9801 et seq. of the Code and applicable state or similar laws.

(f) Tax-Qualified Savings/401(k) Plan. (i) In accordance with Section 6.09(c), effective not later than the Effective Time, Spinco or its affiliates (including Newco) shall have in effect one or more defined contribution plans that include a qualified cash or deferred arrangement within the meaning of Section 401(k) of the Code (and a related trust exempt from tax under Section 501(a) of the Code) (as applicable, the “New 401(k) Plan”). Each Transferred Employee participating in a Newco Benefit Plan that is a defined contribution plan that includes a qualified cash or deferred arrangement within the meaning of Section 401(k) of the Code (the “Newco 401(k) Plan”) immediately prior to the Effective Time shall become a participant in the corresponding New 401(k) Plan as of the Effective Time and each Transferred Employee shall be eligible to participate in a New 401(k) Plan as of the Effective Time.

(ii) Spinco shall, or shall cause Newco to, cause the New 401(k) Plan to accept a “direct rollover” to such New 401(k) Plan of the account balances of each Transferred Employee (including promissory notes evidencing all outstanding loans) under the Newco 401(k) Plan in which such Transferred Employee participates, if such direct rollover is elected in accordance with applicable Law by such Transferred Employee.

(g) Assumed Canadian Plans. (i) Weyerhaeuser shall cause to be assigned and transferred to Newco Canada Exchangeco pursuant to the Canadian Purchase Agreement all rights, obligations and liabilities of the applicable Weyerhaeuser Subsidiaries with respect to the following Newco Canadian Pension Plans: the Weyerhaeuser Saskatchewan Ltd. Pension Plan for Hourly Employees of the Prince Albert Pulp and Paper Division, Saskatchewan, the Big River Lumber Union Employees Pension Plan, the Weyerhaeuser Company Limited Pension Plan for Hourly Employees at Dryden, Ontario and the Weyerhaeuser Canada Ltd. Pension Plan for Hourly Employees of Ear Falls, Ontario (collectively, “Assumed Canadian Plans”). Spinco shall cause Newco Canada Exchangeco to accept pursuant to the Canadian Purchase Agreement such assignment and transfer and assume all liabilities, duties and responsibilities required of it as the successor sponsor of the Assumed Canadian Plans in accordance with the terms thereof and applicable laws. Weyerhaeuser shall cause to be done all things required of the applicable Weyerhaeuser Subsidiaries, and Spinco shall cause to be done all things required of Newco Canada Exchangeco, under applicable laws to establish Newco Canada Exchangeco as successor sponsor to the applicable Weyerhaeuser Subsidiaries under the terms of the Assumed Canadian Plans as provided hereunder. Effective as of the Canadian Asset Sale, Newco Canada Exchangeco will be responsible for all costs and expenses related to the Assumed Canadian Plans, including all contributions required under the terms of such plans or applicable Law in respect of any funding deficiencies thereunder.

(ii) It is understood that assets held pursuant to funding agreements in respect of the Assumed Canadian Plans are invested in a master trust arrangement maintained by the applicable Weyerhaeuser Subsidiary and, as soon as practicable after the Effective Time, such Weyerhaeuser Subsidiary shall cause the interests held by the Assumed Canadian Plans in such master trust to be redeemed or transferred as the case may be in cash or in specie, as determined by the applicable Weyerhaeuser Subsidiary in consultation with Newco Canada Exchangeco. The applicable Weyerhaeuser Subsidiary shall have no obligation to assign or transfer to Newco Canada Exchangeco or to any funding media held by Newco Canada Exchangeco any interest in the said master trust. Subject to the foregoing, Newco shall cause Newco Canada Exchangeco to establish a trust or trusts for the purpose of assuming assets held under the Assumed Canadian Plans or to assume the trusts held under the Assumed Canadian Plans subject to the consent of the trustee thereunder (which the applicable Weyerhaeuser Subsidiary shall use reasonable best efforts to obtain) and provided any trust to be assumed holds no interest in the aforesaid master trust at the time it is assumed. Spinco agrees that the Weyerhaeuser Subsidiary shall be entitled, but shall not be obligated, to transfer the assets of the Assumed Canadian Plans from the master trust to a short-term money market fund. Subject to the direction and authorization of Newco Canada Exchangeco and at the expense of Newco Canada Exchangeco, the applicable Weyerhaeuser Subsidiary shall continue to administer each Assumed Canadian Plan until effective control and direction of the Assumed Canadian Plans is transferred to Newco Canada Exchangeco, which the applicable Weyerhaeuser Subsidiary shall use reasonable best efforts to accomplish as quickly as practicable. For the avoidance of doubt, no Weyerhaeuser Subsidiary shall be construed as the agent of Newco Canada Exchangeco for this purpose. The applicable Weyerhaeuser Subsidiaries’ only responsibility in connection with the Assumed Canadian Plans from the Effective Time to the date effective control is acquired by Newco Canada Exchangeco and all necessary approvals are obtained from the applicable Governmental Entity shall be to execute the directions of Newco Canada Exchangeco. Newco Canada Exchangeco shall indemnify and save harmless each applicable Weyerhaeuser Subsidiary from and against all

damage, liability, loss, expense or cost that each applicable Weyerhaeuser Subsidiary incurs as a result of Newco Canada Exchangeco’s failure to provide directions or authorizations to the applicable Weyerhaeuser Subsidiary or as a result of the applicable Weyerhaeuser Subsidiary’s compliance with directions or authorizations provided by Newco Canada Exchangeco, in each case in connection with the Assumed Canadian Plans on or after the Effective Time. After effective control is acquired by Newco Canada Exchangeco and all necessary approvals are obtained from the applicable Governmental Entity, the applicable Weyerhaeuser Subsidiaries shall have no further obligations or liabilities under any Assumed Canadian Plan or funding arrangement held thereunder and Newco Canada Exchangeco shall be responsible for all obligations, liabilities and commitments relating to such plans both before and after the Effective Time and in respect of Transferred Employees and any other person entitled to rights, benefits or payments under the Assumed Canadian Plans.

(h) Accrued Vacation. For purposes of determining the number of vacation days to which each Transferred Employee shall be entitled, Spinco shall, or shall cause Newco to, assume and honor all vacation days (regular, supplemental or banked) accrued or earned but not yet taken by such Transferred Employee as of the Effective Time. To the extent that a Transferred Employee is entitled under any applicable Law or any policy of Weyerhaeuser or any of its subsidiaries to be paid for any vacation days (regular, supplemental or banked) accrued or earned but not yet taken by such Transferred Employee as of the Effective Time, Spinco shall, or shall cause Newco to, assume the liability for such vacation days.

(i) Administration. Following the date of this Agreement, the parties hereto shall reasonably cooperate in all matters reasonably necessary to effect the transactions contemplated by this Section 6.09, including exchanging information and data relating to workers’ compensation, employee benefits and employee benefit plan coverages (except to the extent prohibited by applicable Law), and in obtaining any governmental approvals required hereunder.

(j) Collectively Bargained Employees. From and after the Effective Time, Spinco shall, or shall cause its affiliates (including Newco) to, comply in all material respects with the terms of all collective bargaining agreements (including all obligations to provide employee benefits and/or to contribute to any pension plans) that cover one or more Transferred Employees (each, a “CBA”) as in effect immediately prior to the Effective Time until such time as Spinco or its affiliates (including Newco) negotiate a new collective bargaining agreement or agreements. Notwithstanding anything to the contrary in this Section 6.09, Spinco further agrees that the provisions of this Section 6.09 shall be subject to any applicable provisions of a CBA in respect of Transferred Employees, to the extent such provisions are inconsistent with or otherwise in conflict with the provisions of any such CBA.

(k) Flexible Spending Account Plans. Effective as of the Effective Time (or, with respect to a Newco Employee who becomes a Transferred Employee after the Effective Time, such later time that such Newco Employee becomes a Transferred Employee), Newco shall assume liabilities and account balances of the Weyerhaeuser Flexible Spending Account Plan maintained in the U.S. with respect to Transferred Employees and their dependents (“U.S. Flexible Spending Account Plans”). Effective as of the Effective Time (or, with respect to a Newco Employee who becomes a Transferred Employee after the Effective Time, such later time that such Newco Employee becomes a Transferred Employee), Weyerhaeuser shall transfer or

cause to be transferred to Newco an amount in cash equal to the excess, if any, of the aggregate contributions for the plan year in which the Effective Time occurs (or, with respect to a Newco Employee who becomes a Transferred Employee after the Effective Time, the plan year in which such Newco Employee becomes a Transferred Employee (such year, the “Transition Year”)) of all Transferred Employees then participating in Weyerhaeuser’s U.S. Flexible Spending Account Plan over the aggregate reimbursements for the plan year in which the Effective Time occurs (or, as applicable, the Transition Year) to all Transferred Employees under such plan. Newco shall cause such amounts to be credited to each such employee’s accounts under Newco’s (or one of its affiliate’s) corresponding U.S. Flexible Spending Account Plan, which shall be established and in effect for such employees as of the Effective Time, and all claims for reimbursement which have not been paid as of the date of the transfer to Newco (or one of its affiliates) and credited under Newco’s (or one of its affiliate’s) U.S. Flexible Spending Account Plan shall be paid pursuant to and under the terms of Newco’s (or one of its affiliate’s) U. S. Flexible Spending Account Plan. In connection with such transfer, Newco shall deem that such employees’ deferral elections made under Weyerhaeuser’s U.S. Flexible Spending Account Plan for the plan year in which the Closing occurs (or, as applicable, the Transition Year) shall continue in effect under Newco’s (or one of its affiliate’s) U.S. Flexible Spending Account Plan for the remainder of the plan year in which the Closing occurs (or, as applicable, the Transition Year).

(l) Canadian Health Spending Account. Effective as of the Effective Time (or with respect to a Newco Employee who becomes a Transferred Employee after the Effective Time, such later time that such Newco Employee becomes a Transferred Employee), Newco shall, under any health spending account plan or arrangement provided by Newco to Transferred Employees employed in Canada, recognize and give credit for all unused account balances of such Transferred Employees, which are maintained under the applicable Weyerhaeuser health spending account at that time.

(m) U.S. Multiemployer Pension Plan. (i) Weyerhaeuser and Domtar intend that the Transactions shall not result in a complete or partial withdrawal by Weyerhaeuser or any Weyerhaeuser Subsidiary from the Multiemployer Pension Plan set forth in Section 4.11(a) of the Weyerhaeuser Disclosure Letter (the “U.S. MEPP”) and Weyerhaeuser and Domtar shall reasonably cooperate to prevent the imposition of a withdrawal liability by the U.S. MEPP in connection with the Transactions, and, effective as of the Closing, Newco shall assume Weyerhaeuser’s obligations to make contributions to the U.S. MEPP.

(ii) In the event that the Transactions are deemed to constitute sale of assets to an unrelated party under Section 4204 of ERISA, then Weyerhaeuser, Newco and Domtar agree that, unless the PBGC waives the requirements of Section 4204(a)(1)(B) of ERISA, if Domtar withdraws from the U.S. MEPP with respect to the Newco Employees within the first five plan years beginning after the Closing and does not pay its liability to such U.S. MEPP on account of such withdrawal, Weyerhaeuser shall be secondarily liable to such plan for any withdrawal liability that Newco would have had to the plan with respect to the Newco Employees in the absence of Section 4204(a) of ERISA, to the extent required by ERISA. Notwithstanding the provisions of the preceding sentence and Section 4204 of ERISA, it is expressly agreed that if Weyerhaeuser or any Weyerhaeuser Subsidiary incurs any secondary withdrawal liability under the preceding sentence, Newco shall indemnify and hold them harmless from any and all losses

incurred by Weyerhaeuser or any Weyerhaeuser Subsidiary by reason of such secondary liability.

(iii) Newco may seek, pursuant to PBGC Regulations §§ 4204.11 and 4204.13, a variance from the bond/escrow requirement of Section 4204(a)(1)(B) of ERISA. Weyerhaeuser shall cooperate with Newco in connection with Newco’s request for such variance, which cooperation shall include: (x) if so requested by Newco, timely and jointly with Newco notifying the U.S. MEPP in writing, as contemplated by PBGC Regulation § 4204.11, of their intention that the Transactions be covered by Section 4204 of ERISA and (y) providing Newco or the U.S. MEPP with such information that is reasonably available to Weyerhaeuser and that Domtar or the U.S. MEPP requests in connection with such request for such variance. If the U.S. MEPP determines that Newco’s request does not qualify for a variance of the bond/escrow requirement, Newco shall provide the bond or escrow required under Section 4204(a)(1)(B) within the time period set forth in PBGC Regulation § 4204.11(d), provided that the foregoing shall not be deemed to restrict the ability of Newco to seek a variance or exemption pursuant to PBGC Regulations §§ 4204.21 and 4204.22.

SECTION 6.10. Directors’ and Officers’ Liability Insurance. (a) As of the Effective Time, Spinco shall have in effect, at no expense to the beneficiaries, policies of directors’ and officers’ liability insurance with respect to claims arising from or related to facts or events which occurred at, before or after the Effective Time. Such policies will be comparable in coverage and amount to Weyerhaeuser directors’ and officers’ liability insurance policy and to the Domtar directors’ and officers’ liability insurance policy in effect as of the date of this Agreement.

(b) Spinco shall for a period of at least six years after the Effective Time, indemnify and hold harmless, and provide advancement of expenses to, all past and present directors or officers of Domtar, Newco and their respective subsidiaries, and each individual who prior to the Effective Time becomes a director or officer of Domtar, Newco and their respective subsidiaries, to the maximum extent allowed under applicable Law in respect of acts or omissions that occurred at or prior to the Effective Time and, in the case of directors and officers of Newco, related to the Newco Business or in connection with any of the Transaction Documents or the Transactions.

(c) Spinco shall maintain in effect for each of the applicable persons referred to in Section 6.10(b) for a period of at least six years after the Effective Time policies of directors’ and officers’ liability insurance of at least the same coverage and containing terms and conditions which are, in the aggregate, no less advantageous to the insured, as the current policies of directors’ and officers’ liability insurance maintained by Domtar or Weyerhaeuser, with respect to claims arising from acts or omissions that occurred at or prior to the Effective Time and, in the case of directors and officers of Newco, related to the Newco Business or in connection with any of the Transaction Documents or the Transactions.

SECTION 6.11. Fees and Expenses. (a) All fees and expenses incurred in connection with the Transactions shall be paid by the party incurring such fees or expenses; provided, however, that in the event the Transactions are consummated, Spinco shall reimburse Weyerhaeuser, Weyerhaeuser Canada and Weyerhaeuser Saskatchewan for (i) all fees and

expenses (including fees and expenses of financial institutions, legal counsel, auditors and title companies) incurred in connection with the financing of the Transaction Debt, including the preparation of the New Debt Commitment Letter and any other financing documents or other documents relating thereto (including any title reports, UCC searches and UCC filings) and roadshows, (ii) up to 50% of all fees and expenses (including fees and expenses of legal counsel, title companies and fees and expenses incurred with respect to efforts to obtain any Consents and Governmental Approvals) incurred in connection with the site separations set forth in Section 6.05 of the Contribution and Distribution Agreement, and (iii) up to an amount of $28,000,000 of all fees and expenses (including fees and expenses of investment bankers, legal counsel, auditors and environmental consultants and fees and expenses incurred with respect to efforts to obtain any Consents or Governmental Approvals) incurred in connection with the Transactions. This Section 6.11 does not relate to Transfer Taxes, which are the subject of Section 2.03 of the Tax Sharing Agreement.

(b) Following the Closing, each of Weyerhaeuser and Spinco shall each be responsible for 50% of the capital expenditures and one-time start-up expenses incurred by either party in connection with the actions required to separate the facilities of Spinco and Weyerhaeuser as disclosed in Section 9.03 of the Weyerhaeuser Disclosure Letter under the heading “Site Services Agreements” (the “Site Separation Costs”). Prior to the Closing, Weyerhaeuser and Domtar shall agree on the procedures to be followed by Weyerhaeuser and Spinco to determine the amount of and methods of reimbursement for such Site Separation Costs.

SECTION 6.12. Public Announcements. Weyerhaeuser and Newco, on the one hand, and Domtar, on the other hand, shall consult with each other and shall mutually agree upon any press release or other public statements with respect to the Transactions and shall not issue any such press release or make any such public statement prior to such consultation and agreement, except as may be required by applicable Law, court process or by obligations pursuant to any listing agreement with the TSX or any U.S. national securities exchange, in which case the party proposing to issue such press release or make such public announcement shall use its reasonable best efforts to consult in good faith with the other parties before issuing any such press release or making any such public announcement.

For the purposes of this Section 6.14, the placement of “help wanted” advertisements, postings on internet job sites and searches by employment search companies that are not specifically targeting employees of Weyerhaeuser, any Weyerhaeuser Subsidiary, Newco or any Newco Subsidiary shall not result in a violation of this Section 6.14.

SECTION 6.17. Distribution. (a) Weyerhaeuser shall use reasonable efforts to ensure that any decision to effect the Distribution, in whole or in part, as an exchange offer will be made sufficiently in advance of receipt of any Governmental Approvals such that the implementation would not reasonably be expected to delay the Closing Date by more than 30 days.

(b) If Weyerhaeuser elects to effect the Distribution, in whole or in part, as an exchange offer, Weyerhaeuser shall use reasonable efforts to and, upon request by Weyerhaeuser, Domtar shall use reasonable efforts to consummate the Distribution within 30 days after satisfaction (or waiver to the extent permissible) of all the conditions precedent to the Closing (other than conditions that by their nature are to be satisfied at the time of the Transactions and shall in fact be satisfied at such time(s)).

(c) Weyerhaeuser shall not use an exchange offer to effect the Distribution, in whole or in part, if such exchange offer would result in occurrence of the Distribution Date 30 days beyond the date on which the Transactions would otherwise be consummated.

SECTION 6.19. Covenants Regarding Non-Solicitation. (a) Subject to Section 6.20, Domtar shall not, directly or indirectly, through any officer, director, employee, representative or agent of Domtar or any of its subsidiaries, (i) solicit, initiate or knowingly encourage (including by way of furnishing information or entering into any form of agreement, arrangement or understanding) the initiation of any inquiries or proposals regarding an Acquisition Proposal, (ii) participate in any discussions or negotiations regarding any Acquisition Proposal, (iii) withdraw or modify in a manner adverse to Weyerhaeuser the approval of the Board of Directors of Domtar of the Transactions or the recommendation of the Board of Directors of Domtar to the holders of Domtar Capital Shares, (iv) approve or recommend any Acquisition Proposal or (v) enter into any agreement, arrangement or understanding related to any Acquisition Proposal. Notwithstanding the preceding part of this Section 6.19(a) and any other provision of this Agreement, nothing shall prevent the Board of Directors of Domtar prior to the issuance of the Final Order from considering, participating in any discussions or negotiations, or entering into a confidentiality agreement and providing information pursuant to Section 6.19(c), regarding an unsolicited bona fide written Acquisition Proposal that did not otherwise result from a breach of this Section 6.19 and that the Board of Directors of Domtar determines in good faith, after consultation with financial advisors and outside counsel, constitutes or is reasonably likely to result in a Superior Proposal; provided, however, that prior to taking such action, the Board of Directors must have determined, after consultation with outside counsel, that it is appropriate for the Board of Directors of Domtar take such action in order to discharge properly its fiduciary duties. Domtar shall not consider, negotiate, accept, approve or recommend an Acquisition Proposal after the date of the issuance of the Final Order. Domtar shall, and shall cause the officers, directors, employees,

representatives and agents of Domtar and its subsidiaries to, cease immediately all discussions and negotiations conducted prior to the date of this Agreement regarding any proposal that constitutes, or may reasonably be expected to lead to, an Acquisition Proposal. Nothing contained in this Section 6.19(a) shall prohibit Domtar from responding to any unsolicited proposal or inquiry solely by advising the person making such proposal or inquiry of the terms of this Section 6.19(a).

(b) Domtar shall promptly notify Weyerhaeuser, at first orally and then in writing, of any Acquisition Proposal and any inquiry that could lead to an Acquisition Proposal, or any amendments to the foregoing, or any request for non-public information relating to Domtar or any material Domtar Subsidiary in connection with an Acquisition Proposal or for access to the properties, books or records of Domtar or any material Domtar Subsidiary by any person that informs Domtar or such material Domtar Subsidiary that it is considering making, or has made, an Acquisition Proposal. Such notice shall include a description of the material terms and conditions of any proposal, the identity of the person making such proposal, inquiry or contact and provide such other details of the proposal, inquiry or contact as Weyerhaeuser may reasonably request. Domtar shall (i) keep Weyerhaeuser fully informed of the status including any change to the material terms of any such Acquisition Proposal or inquiry and (ii) provide to Weyerhaeuser, as soon as practicable after receipt or delivery thereof, copies of all correspondence and other written material sent or provided to Domtar or any Domtar Subsidiary from any person in connection with any Acquisition Proposal or sent or provided by Domtar to any person in connection with any Acquisition Proposal.

(c) If Domtar receives a request for material non-public information from a person who has made an unsolicited bona fide written Acquisition Proposal and Domtar is permitted, as contemplated under the second sentence of Section 6.19(a), to negotiate the terms of such Acquisition Proposal, then, and only in such case, the Board of Directors of Domtar may, subject to the execution by such person of a confidentiality agreement containing a standstill provision substantially similar to that contained in the Confidentiality Agreement, provide such person with access to information regarding Domtar; provided, however, that the person making the Acquisition Proposal shall not be precluded under such confidentiality agreement from making the Acquisition Proposal (including any amendment thereto); provided further that Domtar sends a copy of any such confidentiality agreement to Weyerhaeuser promptly upon its execution and Weyerhaeuser is provided with a list of or copies of the information provided to such person and immediately provided with access to similar information to which such person was provided.

(d) Domtar shall ensure that its officers, directors and employees and its subsidiaries and their officers, directors and employees and any financial advisors or other advisors or representatives retained by it are aware of the provisions of this Section 6.19, and it shall be responsible for any breach of this Section 6.19 by its officers, directors, employees, financial advisors or other advisors or representatives.

(e) Notwithstanding Section 6.19(a)(iii), the Board of Directors of Domtar may withdraw or modify in a manner adverse to Weyerhaeuser the approval of the Board of Directors of Domtar of the transactions contemplated hereby if an event has occurred and is continuing

that, either alone or together with other events, has had or would reasonably be expected to have a Newco Material Adverse Effect.

SECTION 6.20. Notice by Domtar of Superior Proposal Determination.

(a) Notwithstanding Sections 6.19(a), 6.19(b), 6.19(d) and 6.19(e), Domtar may accept, approve, recommend or enter into any agreement, understanding or arrangement in respect of a Superior Proposal if, and only if, (i) it has provided Weyerhaeuser with a copy of the Superior Proposal document, (ii) five Business Days shall have elapsed from the later of the date Weyerhaeuser received written notice advising Weyerhaeuser that Domtar’s Board of Directors has resolved, subject only to compliance with this Section 6.20 and termination of this Agreement, to accept, approve, recommend or enter into an agreement in respect of such Superior Proposal, specifying the terms and conditions of such Superior Proposal and identifying the person making such Superior Proposal, and the date Weyerhaeuser received a copy of such Superior Proposal, and (iii) it has previously or concurrently will have (A) paid to Weyerhaeuser the Break Fee (as defined in Section 6.21(a)(iii)), if any, payable under Section 6.21 and (B) terminated this Agreement pursuant to Section 8.01(d)(ii). Any information provided by Domtar to Weyerhaeuser pursuant to this Section 6.20 or pursuant to Section 6.19 shall be subject to Section 6.06.

(b) During such five Business Day period, Domtar agrees that Weyerhaeuser shall have the right, but not the obligation, to offer to amend the terms of this Agreement. The Board of Directors of Domtar will review any offer by Weyerhaeuser to amend the terms of this Agreement in good faith in order to determine, in its discretion in the exercise of its fiduciary duties, whether Weyerhaeuser’s offer upon acceptance by Domtar would result in such Superior Proposal ceasing to be a Superior Proposal. If the Board of Directors of Domtar so determines, it will enter into an amended agreement with Weyerhaeuser reflecting Weyerhaeuser’s amended proposal. If the Board of Directors of Domtar continues to believe, in good faith and after consultation with financial advisors and outside counsel, that such Superior Proposal remains a Superior Proposal and therefore rejects Weyerhaeuser’s amended proposal, Domtar may terminate this Agreement pursuant to Section 8.01(d)(ii); provided, however, that Domtar must concurrently pay to Weyerhaeuser the Break Fee, if any, payable to Weyerhaeuser under Section 6.21 and must concurrently with such termination enter into a definitive agreement with respect to such Acquisition Proposal. Domtar acknowledges and agrees that payment of the Break Fee, if any, payable under Section 6.21 is a condition to valid termination of this Agreement under Section 8.01(d)(ii) and this Section 6.20.

(c) Domtar also acknowledges and agrees that each successive modification of any Acquisition Proposal shall constitute a new Acquisition Proposal for purposes of the requirement under clause (ii) of Section 6.20(a) to initiate an additional five Business Day notice period.

SECTION 6.21. Break Fee.

(a) If:

(i) Domtar shall terminate this Agreement pursuant to Section 8.01(d)(ii), unless at the time of such termination, an event has occurred and is continuing that has a Newco Material Adverse Effect;

(ii) Weyerhaeuser shall terminate this Agreement pursuant to Section 8.01(c)(ii), unless at the time of such failure to recommend, withdrawal or adverse modification or change, or recommendation of an Acquisition Proposal, an event has occurred and is continuing that has a Newco Material Adverse Effect; or

(iii) either Domtar or Weyerhaeuser shall terminate this Agreement pursuant to Section 8.01(b)(i) or 8.01(b)(ii) in circumstances where Domtar Shareholder Approval has not been obtained at the Domtar Meeting, and (x)(A) in the case of a termination of this Agreement pursuant to Section 8.01(b)(i), a bona fide Acquisition Proposal has been made by any person other than a Weyerhaeuser Party prior to the Domtar Meeting and not withdrawn more than five days prior to the vote of the Domtar Shareholders, or (B) in the case of a termination of this Agreement pursuant to Section 8.01(b)(ii), a bona fide Acquisition Proposal has been made by any Person other than a Weyerhaeuser Party that is either publicly disclosed or otherwise becomes publicly known prior to or at the time of the Domtar Meeting and that is not withdrawn more than five days prior to the vote of the Domtar Shareholders, and (y) Domtar enters into an agreement with respect to any Acquisition Proposal, or any Acquisition Proposal is consummated, after the date hereof and prior to the expiration of 12 months following termination of this Agreement, unless at the time of the Domtar Meeting an event has occurred and is continuing that has a Newco Material Adverse Effect;

then in any such case Domtar shall pay to Weyerhaeuser $62,000,000 (the “Break Fee”) in immediately available funds to an account designated by Weyerhaeuser. Such payment shall be due (A) in the case of a termination specified in clause (i), prior to the termination of this Agreement, (B) in the case of a termination specified in clause (ii), within five Business Days after written notice of termination by Weyerhaeuser, or (C) in the case of a termination specified in clause (iii), at or prior to the earlier of the entering into of the agreement and the consummation of the transaction referred to therein; provided, however, that in the event that Domtar has reimbursed Weyerhaeuser for its out-of-pocket expenses pursuant to Section 6.21(b) prior to the date on which the Break Fee is payable, then the amount of the Break Fee payable shall be reduced by the amount of expenses actually reimbursed by Domtar pursuant to Section 6.21(b). Domtar shall not be obligated to make more than one payment pursuant to this Section 6.21(a).

(b) Domtar shall reimburse Weyerhaeuser for all its out-of-pocket expenses actually incurred in connection with this Agreement and the Transactions, subject to a maximum of $10,000,000, if this Agreement is terminated in the circumstances specified in clause (iii) of Section 6.21(a) and the Break Fee is not payable upon the date of such termination. Such reimbursement shall be paid on demand following such termination.

SECTION 6.22. Effect of Break Fee Payment. For greater certainty, the parties hereto agree that if Domtar pays to Weyerhaeuser amounts required by Section 6.21 as a result of the occurrence of any of the events referenced in Section 6.21, the Weyerhaeuser Parties shall have no other remedy for monetary damages for any breach of this Agreement by Domtar.

SECTION 6.23. Securities Act Exemptions. In the event that, due to an amendment to the Securities Act, a change in the SEC’s interpretation of the Securities Act or a decision of a court which provides that orders of Canadian courts such as the Final Order do not qualify under Section 3(a)(10) of the Securities Act, the exemption from registration under Section 3(a)(10) of the Securities Act is not available for any reason to exempt the issuance of the Spinco Shares and Exchangeable Shares in accordance with the Arrangement from the registration requirements of the Securities Act, then Spinco shall take all necessary action to file a registration statement on Form S-4 (or on such other form that may be available to Spinco) in order to register the shares of Spinco Common Stock and Exchangeable Shares, and shall use its reasonable best efforts to cause such registration statement to become effective at or prior to the Effective Time. In the event that, prior to the Distribution Date, due to an amendment to the Securities Act, a change in the SEC’s interpretation of the Securities Act or a decision of a court, the Distribution by means of a dividend is required to be registered under the Securities Act, then Weyerhaeuser shall cause Spinco to take all necessary action to file a registration statement on Form S-1 (or such other form that may be available to Spinco) in order to register the shares of Spinco Common Stock to be distributed as a dividend and shall cause Spinco to use its reasonable best efforts to cause such registration statement to become effective at or prior to the Distribution Date.

SECTION 6.24. Audited Financial Statements. (a) As soon as practicable after the date hereof, but no later than November 15, 2006, Weyerhaeuser shall deliver to Domtar (i) audited balance sheets with respect to the Newco Business as of December 25, 2005 and December 26, 2004 (together with the notes thereto, the “Audited Newco Balance Sheets”), and the related audited statements of results of operations and cash flows for each of the three years in the three-year period ended December 25, 2005 (together with the notes thereto and the Audited Newco Balance Sheets, the “Audited Newco Financial Statements”), which shall be substantially the same as the 2005 Unaudited Newco Financial Statements with respect to the period covered by such unaudited financial statements (except that the 2005 Unaudited Newco Financial Statements do not reflect the Canadian Logging, Forest Management and Saw Mill Operations, which shall be reflected in the Audited Newco Financial Statements), with audit adjustments that are only immaterial in amount and nature (except with respect to the Canadian Logging, Forest Management and Saw Mill Operations), (ii) an unqualified audit report on the Audited Newco Financial Statements, and (iii) a schedule showing all adjustments to the 2005 Unaudited Newco Financial Statements to reflect the Canadian Logging, Forest Management and Saw Mills Operations.

(b) The parties hereto will cooperate with each other and use their respective reasonable best efforts to prepare on a timely basis pro forma financial statements of Spinco, as adjusted to reflect the consummation of the Transactions, prepared in accordance with Regulation S-X promulgated by the SEC and applicable Canadian requirements, for the periods required to be included in the Domtar Circular, the Form 10, the Spinco Registration Statement

or, if such filings are required by applicable Law or the SEC, the Form S-4 or the Exchange Offer Schedule.

SECTION 6.25. Domtar Share Purchase Plans and Domtar Stock Plans. (a) As soon as practicable following the date of this Agreement, the Board of Directors of Domtar shall adopt such resolutions or take such other actions as may be required to provide that with respect to the Domtar Share Purchase Plan for Canadian Employees and the Domtar Share Purchase Plan for Employees in the United States (collectively, the “Domtar ESPPs”) (A) each participant’s outstanding right to purchase Domtar Common Shares under the Domtar ESPPs shall terminate on the last trading day immediately prior to the Measurement Date, (B) any amounts allocated to a participant’s account under the Domtar ESPPs may be used to purchase Domtar Common Shares from Domtar prior to, but not after, the close of business on the day prior to the Measurement Date, and any unused amounts shall be refunded to such participant, (C) the Domtar ESPPs shall terminate at the close of business on the day immediately prior to the Measurement Date, (D) with respect to the Domtar ESPP for Canadian employees, the annual employer contribution for the calendar year ended December 31, 2006 shall be made to participants’ accounts on the day immediately prior to the Measurement Date (if not previously made), and (E) no further rights shall be outstanding under the Domtar ESPPs (other than Domtar Rights relating to Domtar Common Shares previously purchased under the Domtar ESPPs). After the Effective Time, the Board of Directors of Spinco may decide, at its discretion, whether it shall institute replacement share purchase plans for Spinco employees.

SECTION 6.26. Furnishing of Tax Opinion. At least 10 days prior to the Distribution Date, Weyerhaeuser shall furnish to Domtar a copy of the proposed form of the tax opinion described in Section 7.02(e) together with all letters or certificates that form the basis therefor (collectively, the “Opinion Materials”). Domtar shall be entitled to provide Weyerhaeuser with written comments on such Opinion Materials. Weyerhaeuser shall consider such comments and shall make changes to the Opinion Materials in accordance with such comments, but only to the extent that Weyerhaeuser, acting in good faith, determines that such changes are reasonable. Weyerhaeuser shall furnish Spinco with a copy of the final Opinion Materials. The Opinion Materials shall not include any letter, certificate or other item to which any Spinco Party is a signatory other than Section 6.26 of the Weyerhaeuser Disclosure Letter.

SECTION 6.27. IRS Ruling. (a) Weyerhaeuser and Spinco shall use their reasonable best efforts to seek, as promptly as practicable, a private letter ruling from the IRS, in form and substance reasonably satisfactory to Weyerhaeuser (the “IRS Ruling”) to the effect that the Contribution and the Distribution shall qualify as a tax-free transaction under Sections 355 and 368 of the Code. Weyerhaeuser shall use its reasonable best efforts to notify Domtar’s tax counsel about any substantive telephone communications with the IRS regarding any material issues arising with respect to the IRS Ruling, so that such counsel may participate on such calls; provided, however, that if advance notification to such counsel of a call with the IRS is not practically feasible due to the initiation of an unscheduled call by the IRS, Weyerhaeuser shall first attempt to include Domtar’s tax counsel on such call and, if unsuccessful, shall timely inform Domtar’s tax counsel of any material issues discussed with the IRS subsequent to the call. Domtar’s tax counsel shall be allowed to participate in any in-person conference with the IRS (and Weyerhaeuser agrees to take such actions as the IRS may reasonably request in order to permit such participation), unless the IRS objects to such participation or such participation will

unreasonably delay the holding of the conference. If Domtar’s tax counsel participates in any in-person conference with the IRS, such participation shall be for the limited purposes of providing additional facts and improving the clarity of the discussion relating to Domtar’s role in the Transactions.

(b) The IRS Ruling may be based upon customary factual statements, representations and covenants by the parties, their subsidiaries and their shareholders, consistent with the existing published guidance of the IRS, in each case with appropriate modifications to reflect the particular facts of the Transactions (collectively, the “Representations”). Subject to, and consistent with, Section 6.06, Domtar agrees to provide such appropriate information and Representations as the IRS shall reasonably request in connection with the IRS Ruling. In the event that the IRS will not issue the ruling requested by Weyerhaeuser, then Weyerhaeuser and Domtar shall consider in good faith any reasonable modifications to the structure of the Transactions that will facilitate receipt of the IRS Ruling, so long as such modifications will not materially adversely affect the value of the Transactions to either party or its shareholders.

(c) Weyerhaeuser shall be responsible for the preparation and filing of the request for the IRS Ruling and supplements thereto to be submitted to the IRS in connection with the IRS Ruling (the “IRS Submission”). Prior to submitting any IRS Submission, Weyerhaeuser shall provide Domtar’s tax counsel with a reasonable opportunity to review and comment on a draft of such IRS Submission; provided, however, Weyerhaeuser may redact from such draft of such IRS Submission any information that (x) Weyerhaeuser, in its good faith judgment, considers to be confidential information not germane to the IRS Ruling and to which Domtar is not otherwise entitled to have access to pursuant to Section 6.06 and (y) is not (and is not reasonably expected to become) a part of any other publicly available information. Weyerhaeuser shall timely provide to Domtar’s tax counsel a final copy of any IRS Submission.

(d) Weyerhaeuser shall timely provide Domtar and its tax counsel with a copy of the IRS Ruling after receipt thereof from the IRS.

SECTION 6.28. Equity Calculation. On the Measurement Date, Weyerhaeuser shall provide Domtar with all relevant information regarding elections by Rollover Employees to receive Substituted Spinco Options, Substituted Spinco SARs, Substituted Spinco RSUs and the number of shares of Spinco Common Stock issuable pursuant thereto, and Domtar shall provide Weyerhaeuser with a statement setting forth the total number of Domtar Common Shares then issued and outstanding and all relevant information with respect to (i) the Domtar Restricted Shares and the number of additional Domtar Common Shares issuable pursuant thereto, and (ii) the Domtar Options, Domtar Rights, Domtar DSUs, Domtar PSUs and the number of Domtar Common Shares to be granted pursuant thereto, in each case for the purpose of determining the number of shares of Spinco Common Stock to be issued to Weyerhaeuser on the Contribution Date in accordance with Section 2.12(b) of the Contribution and Distribution Agreement. On the basis of this information, Weyerhaeuser and Domtar shall calculate in good faith the number of shares of Spinco Common Stock to be issued to Weyerhaeuser pursuant to such Section 2.12. Weyerhaeuser shall determine the Measurement Date in accordance with Section 2.12(b) of the Contribution and Distribution Agreement and shall provide Domtar with three Business Days’ prior notice of such date.

SECTION 6.29. Redemption of Excluded IRB Indebtedness. Prior to the Closing Date, Weyerhaeuser shall redeem all Excluded IRB Indebtedness so that (i) all Weyerhaeuser’s obligations in respect of such indebtedness shall have been satisfied in full, and (ii) all Liens on Newco Assets securing such Excluded IRB Indebtedness shall have been irrevocably released and terminated.

SECTION 6.30. Confidentiality. (a) Domtar and its affiliates acknowledge that the information being provided to them in connection with the Transactions is subject to the terms of the Confidentiality Agreement, which are incorporated herein by reference. Effective upon, and only upon, the Closing, the Confidentiality Agreement shall terminate with respect to information relating solely to the Newco Business; provided, however, that Domtar acknowledges that any and all other information provided to it by Weyerhaeuser, any of its affiliates or their respective representatives concerning Weyerhaeuser or any of its affiliates shall remain subject to the terms and conditions of the Confidentiality Agreement after the Closing.

(b) Weyerhaeuser shall keep confidential, and cause its affiliates and instruct its and their officers, directors, employees and advisors to keep confidential, all information relating to the Newco Business except as required by law or administrative process and except for information which is available to the public on the Closing Date, or thereafter becomes available to the public other than as a result of a breach of this Section 6.30(b). The covenants set forth in this Section 6.30 shall terminate two years after the Closing Date.

SECTION 6.31. Internal Controls. The parties hereto will cooperate with each other and use their respective reasonable best efforts to (A) design a system of internal controls over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) sufficient to provide reasonable assurances regarding the reliability of financial reporting by Spinco after the Effective Time, and the preparation of financial statements of Spinco after the Effective Time for external purposes, and (B) design disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act) to ensure that material information that Spinco will be required to disclose after the Effective Time in the reports it is required to file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and is accumulated and communicated to Spinco’s management as appropriate to allow timely decisions regarding required disclosure and to make the certifications of the principal executive officer and principal financial officer of Spinco required pursuant to Sections 302 and 906 of the Sarbanes-Oxley Act of 2002, as amended (the “Sarbanes-Oxley Act”).

SECTION 6.32. Spinco Common Stock Matters. Prior to the Distribution, whether effected pursuant to a dividend or an exchange offer or a combination thereof, Weyerhaeuser shall and shall cause Spinco to either, at Weyerhaeuser’s election and pursuant to documents reasonably acceptable to Domtar, (i) adopt and enter into a “shareholder rights plan” for Spinco containing customary terms and conditions and a threshold of 10% for the definition of “acquiring person” and similar terms or (ii) amend the Restated Certificate of Incorporation of Spinco attached hereto as Exhibit A in order to provide for a limitation on the ability of any person to have or acquire beneficial ownership of Spinco Common Stock equal to or greater than 10% of the issued and outstanding shares of such stock. Any such plan or amendment (A) shall have a term of two years, (B) shall not apply to any person who is and remains eligible to file a

Schedule 13G under the Exchange Act and (C) shall, with respect to any person who has greater than 10% of the issued and outstanding shares of such stock immediately following the Closing in the event that the Distribution is effected in whole as a pro rata dividend, only apply to the extent such person acquires additional shares of such stock.

If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule or Law, or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the Transactions is not affected in any manner materially adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible to the end that the Transactions are fulfilled to the extent possible.

SECTION 9.06. Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be deemed an original and all of which shall be considered one and the same agreement, and shall become effective when one or more counterparts have been signed by each of the parties hereto and delivered to the other parties.

SECTION 9.07. Entire Agreement; No Third-Party Beneficiaries. The Transaction Documents, taken together with the Domtar Disclosure Letter and the Weyerhaeuser Disclosure Letter, constitute the entire agreement, and supersede all prior agreements and understandings, both written and oral, among the parties hereto with respect to the Transactions and are not intended to confer upon any person other than the parties hereto any rights or remedies. Notwithstanding the immediately preceding sentence, following the Effective Time the provisions of Article II shall be enforceable by any person entitled to shares of Spinco Common Stock pursuant to Article II of this Agreement and the provisions of Section 6.10 shall be enforceable by the specified beneficiaries thereof.

SECTION 9.08. Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, regardless of the laws that might otherwise govern under applicable principles of conflicts of laws thereof, except to the extent the laws of Canada and of the Province of Québec are applicable to the Arrangement.

SECTION 9.09. Assignment. Neither this Agreement nor any of the rights, interests or obligations under this Agreement shall be assigned, in whole or in part, by operation of law or otherwise by any of the parties hereto without the prior written consent of the other parties. Any purported assignment without such consent shall be void. Subject to the preceding sentences, this Agreement will be binding upon, inure to the benefit of, and be enforceable by, the parties hereto and their respective successors and assigns.

SECTION 9.10. Enforcement. The parties hereto agree that irreparable damage would occur in the event that any of the provisions of any Transaction Document were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties hereto shall be entitled to an injunction or injunctions to prevent breaches of any Transaction Document and to enforce specifically the terms and provisions of each Transaction Document in any Federal court, located in the State of Delaware or, if such federal courts do not have subject matter jurisdiction in any Delaware state court, this being in addition to any other remedy to which they are entitled at law or in equity. In addition, each of the parties hereto (a) consents to submit itself to the personal jurisdiction of any Federal court located in the State of Delaware or if such federal courts do not have subject matter jurisdiction in any Delaware state court in the event any dispute arises out of any Transaction Document or any Transaction, (b) agrees that it will not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such court, (c) agrees that it will not bring any action relating to any Transaction Document or any Transaction in any court other than any Federal court sitting in the State of Delaware or any Delaware state court and (d) waives any right to trial by jury with respect to any action related to or arising out of any Transaction Document or any Transaction.

SECTION 9.11. Certain Matters. In the event that for any reason Domtar does not obtain the listing and posting for trading of the Class B Common Shares on the TSX, Domtar and Weyerhaeuser shall agree to such amendments to this Agreement and the other Transaction Documents as shall be reasonably necessary to eliminate the Class B Common Shares from the structure for the Transactions set forth herein, including the deletion of the reference to the Class B Common Shares in Section 7.01(e).

The number of authorized shares of any of the Preferred Stock or the Common Stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of a majority in voting power of the stock of the Corporation entitled to vote thereon irrespective of the provisions of Section 242(b)(2) of the DGCL (or any successor provision thereto), and no vote of the holders of any of the Preferred Stock, the Special Voting Stock or the Common Stock voting separately as a class shall be required therefor.

The Board of Directors of the Corporation (the “Board of Directors”) is hereby expressly authorized, by resolution or resolutions, to provide, out of the unissued shares of Preferred Stock, for series of Preferred Stock and, with respect to each such series, to fix the number of shares constituting such series and the designation of such series, the voting powers (if any) of the shares of such series, and the preferences and relative, participating, optional or other special rights, if any, and any qualifications, limitations or restrictions thereof, of the shares of such series.

(a) Number of Shares. There shall be one share of Special Voting Stock.

(i) The holder of the share of Special Voting Stock shall be entitled to vote on each matter on which holders of the Common Stock or stockholders generally are entitled to vote, and the holder of the share of Special Voting Stock shall be entitled to cast on each such matter a number of votes equal to the number of shares of Common Stock into which the exchangeable shares of [Newco Canada Exchangeco] (the “Exchangeable Shares”) outstanding on the record date for holders of Common Stock entitled to vote on any such matter are then exchangeable (A) that are not owned by the Corporation or its affiliates and (B) as to which the holder of the share of Special Voting Stock has timely received, as determined pursuant to the Voting and Exchange Trust Agreement to

(ii) Except as otherwise provided herein or by applicable law, the holder of the share of Special Voting Stock and the holders of shares of Common Stock shall vote together as one class for the election of directors of the Corporation and on all other matters submitted to a vote of stockholders of the Corporation and any directors so elected shall be classified as provided in Article IV.

(d) Liquidation Rights.

(i) In the event of voluntary or involuntary liquidation, dissolution or winding up of the Corporation, the holder of the share of Special Voting Stock shall be entitled to receive out of the assets of the Corporation available for distribution to the stockholders, an amount equal to $0.01 before any distribution is made on the Common Stock of the Corporation or any other stock ranking junior to the Special Voting Stock as to distribution of assets upon voluntary or involuntary liquidation. After payment of the full amount of the liquidation preference of the share of Special Voting Stock, the holder of the share of Special Voting Stock shall not be entitled to any further participation in any distribution of assets of the Corporation.

(ii) For the purposes of this Section 2.03(d), neither the sale, conveyance, exchange or transfer (for cash, shares of stock, securities or other consideration) of all or substantially all of the property or assets of the Corporation nor the consolidation or merger of the Corporation with or into one or more other entities shall be deemed to be a voluntary or involuntary liquidation.

(e) No Redemption; No Sinking Fund.

(i) The share of Special Voting Stock shall not be subject to redemption by the Corporation or at the option of its holder, except that at such time as no Exchangeable Shares (other than Exchangeable Shares owned by the Corporation or its affiliates) shall be outstanding, the share of Special Voting Stock shall automatically be redeemed and canceled with an amount of $0.01 due and payable upon such redemption.

(ii) The share of Special Voting Stock shall not be subject to or entitled to the operation of a retirement or sinking fund.

(f) Approvals. During the term of the Voting Agreement, the Corporation shall obtain the consent of the holders of the Exchangeable Shares in order

A-3

to issue any shares of Special Voting Stock in addition to the share of Special Voting Stock and shall obtain approval of the holder of the share of Special Voting Stock in order to amend any other term of the Special Voting Stock.

SECTION 2.04. Common Stock. (a) General. The Common Stock shall be subject to the express terms of the Preferred Stock and any series thereof.

(b) Voting Rights. Each holder of Common Stock shall be entitled to one vote for each share of Common Stock held of record by such holder on all matters on which stockholders generally are entitled to vote; provided, however, that, except as otherwise required by law, holders of Common Stock shall not be entitled to vote on any amendment to this Restated Certificate of Incorporation (including any certificate filed pursuant to the DGCL (“Certificate of Designation”) relating to any series of Preferred Stock) that relates solely to the terms of one or more outstanding series of Preferred Stock if the holders of such affected series are entitled, either separately or together with the holders of one or more other such series, to vote thereon pursuant to this Restated Certificate of Incorporation (including any Certificate of Designation relating to any series of Preferred Stock) or pursuant to the DGCL. Except as otherwise provided by law, by this Restated Certificate of Incorporation (including any Certificate of Designation) or by the resolution or resolutions adopted by the Board of Directors designating any series of Preferred Stock, the Common Stock shall have the exclusive right to vote for the election of the members of the Board of Directors (each, a “Director”) and for all other purposes, and holders of Preferred Stock shall not be entitled to receive notice of any meeting of stockholders at which they are not entitled to vote.

(c) Dividends and Distributions. Subject to Section 2.03(b), and subject to the rights of any class or series of stock having a preference over the Common Stock as to dividends, the holders of the shares of Common Stock shall be entitled to receive such dividends and other distributions in cash, stock or property of the Corporation as may be declared on the Common Stock by the Board of Directors at any time or from time to time out of any funds legally available therefor.

(d) Liquidation Rights. In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Corporation, and subject to the rights of any class or series of stock having a preference over the Common Stock as to the distribution of assets upon liquidation, dissolution or winding up of the Corporation, the holders of shares of Common Stock shall be entitled to receive all of the remaining assets of the Corporation available for distribution to its stockholders, ratably in proportion to the number of shares of Common Stock held by them.

SECTION 2.05. Stock Ownerhip. The Corporation shall be entitled to treat the person in whose name any share of its stock is registered as the owner thereof for all purposes and shall not be bound to recognize any equitable or other claim to, or interest in, such share on the part of any other person, whether or not the Corporation shall have notice thereof, except as expressly provided by applicable law.

ARTICLE III

STOCKHOLDER ACTION

SECTION 3.01. Stockholder Action. Any action required or permitted to be taken by the stockholders of the Corporation must be effected at a duly called annual or special meeting of such holders and may not be effected by any consent in writing by such holders. Except as otherwise provided by law, this Restated Certificate of Incorporation (including any Certificate of Designation), the Restated By-laws of the Corporation (the “By-laws”), applicable stock exchange rules or other rules and regulations applicable to the Corporation, in all matters other than the election of Directors, the affirmative vote of a majority of the voting power of the outstanding shares present in person or represented by proxy at the meeting and entitled to vote on the matter shall be the act of the stockholders. Except as otherwise required by law and subject to the rights of the holders of any series of Preferred Stock or any class or series of stock having a preference over the Common Stock as to dividends or upon liquidation, dissolution or winding up, special meetings of stockholders of the Corporation for any purpose or purposes may be called only by the Board of Directors pursuant to a resolution stating the purpose or purposes thereof approved by a majority of the total number of Directors which the Corporation would have if there were no vacancies (the “Whole Board”) or by the Chairman of the Board of Directors. No business other than that stated in the notice of meeting shall be transacted at any special meeting of stockholders.

ARTICLE IV

BOARD OF DIRECTORS

SECTION 4.01. Election of Directors. Unless and except to the extent that the By-laws shall so require, the election of Directors of the Corporation need not be by written ballot. Subject to the rights of the holders of any series of Preferred Stock or any class or series of stock having a preference over the Common Stock as to dividends or upon liquidation, dissolution or winding up to elect Directors under this Restated Certificate of Incorporation or any resolution or resolutions providing for the issue of such class or series of stock adopted by the Board of Directors, a plurality of the votes cast at a duly called annual or special meeting of stockholders shall be the vote required to elect Directors.

SECTION 4.02. Number and Terms. Except as otherwise fixed by or pursuant to the provisions of Article II hereof relating to the rights of the holders of any series of Preferred Stock or any class or series of stock having a preference over the Common Stock as to dividends or upon liquidation, dissolution or winding up to elect additional Directors under specified circumstances, the number of the Directors shall be fixed from time to time exclusively pursuant to a resolution adopted by a majority of the Whole Board (but shall not be less than three). Subject to Section 4.06, the Directors

A-5

shall be classified, with respect to the time for which they severally hold office, into three classes, as nearly equal in number as possible, one class to be originally elected for a term expiring at the first annual meeting of stockholders following the effectiveness of this Restated Certificate of Incorporation, another class to be originally elected for a term expiring at the second annual meeting of stockholders following the effectiveness of this Restated Certificate of Incorporation, and another class to be originally elected for a term expiring at the third annual meeting of stockholders following the effectiveness of this Restated Certificate of Incorporation, with each Director to hold office until such person’s successor is duly elected and qualified. At each annual meeting of stockholders, Directors elected to succeed those Directors whose terms then expire shall be elected for a term of office to expire at the third succeeding annual meeting of stockholders after their election, with each Director to hold office until such person’s successor shall have been duly elected and qualified.

SECTION 4.03. Newly Created Directorships And Vacancies. Except as otherwise provided for or fixed by or pursuant to the provisions of Article II relating to the rights of the holders of any series of Preferred Stock or any class or series of stock having a preference over the Common Stock as to dividends or upon liquidation, dissolution or winding up to elect Directors under specified circumstances, newly created directorships resulting from any increase in the number of Directors and any vacancies on the Board of Directors resulting from death, resignation, disqualification, removal or other cause shall be filled by the affirmative vote of a majority of the remaining Directors then in office, even though less than a quorum of the Board of Directors, and not by the stockholders. Any Director elected in accordance with the preceding sentence shall hold office for the remainder of the full term of the class of Directors in which the new directorship was created or the vacancy occurred and until such Director’s successor shall have been duly elected and qualified. No decrease in the number of Directors constituting the Board of Directors shall shorten the term of any incumbent Director.

SECTION 4.04. Removal. Subject to the rights of any class or series of stock having a preference over the Common Stock as to dividends or upon liquidation to elect Directors under specified circumstances, any director may be removed from office only for cause and only by the affirmative vote of the holders of at least 75% of the voting power of all shares of the Corporation entitled to vote generally in the election of Directors (the “Voting Stock”) then outstanding, voting together as a single class.

SECTION 4.05. Preferred Stock. Notwithstanding the foregoing, whenever the holders of any series of Preferred Stock or any class or series of stock having a preference over the Common Stock as to dividends or upon liquidation, dissolution or winding up shall have the right, voting separately by series, to elect Directors under specified circumstances, the election, term of office, filling of vacancies and other features of such directorships shall be governed by the terms of this Restated Certificate of Incorporation applicable thereto, and such Directors so elected shall not be classified pursuant to this Article IV unless expressly provided by the terms of such series of Preferred Stock.

ARTICLE VII

LIMITED LIABILITY; INDEMNIFICATION

SECTION 7.01. Limited Liability of Directors. A Director shall not be personally liable to the Corporation or its stockholders for monetary damages for breach of fiduciary duty as a Director, except to the extent such exemption from liability or limitation thereof is not permitted by the DGCL. Neither the amendment nor repeal of this Section 7.01 shall eliminate or reduce the effect of this Section 7.01 in respect of any matter occurring, or any cause of action, suit or claim that, but for this Section 7.01, would accrue or arise, prior to such amendment or repeal.

SECTION 7.02. Indemnification and Insurance. (a) Right To Indemnification. Each person who was or is made a party or is threatened to be made a party to or is involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative (hereinafter a “Proceeding”), by reason of the fact that such person, or a person of whom such person is the legal representative, is or was a

A-7

Director or officer of the Corporation or, while a Director or officer of the Corporation, is or was serving at the request of the Corporation as a Director, officer, employee or agent of another corporation or of a partnership, joint venture, trust or other enterprise, including service with respect to employee benefit plans, whether the basis of such Proceeding is alleged action in an official capacity as a Director, officer, employee or agent or in any other capacity while serving as a Director, officer, employee or agent, shall be indemnified and held harmless by the Corporation to the fullest extent authorized by the DGCL, as the same exists or may hereafter be amended, against all expense, liability and loss (including attorneys’ fees, judgments, fines, amounts paid or to be paid in settlement, and excise taxes or penalties arising under the Employee Retirement Income Security Act of 1974, as in effect from time to time) reasonably incurred or suffered by such person in connection therewith and such indemnification shall continue as to a person who has ceased to be a Director, officer, employee or agent and shall inure to the benefit of such person’s heirs, executors and administrators; provided, however, that, except as provided in paragraph (b) hereof, the Corporation shall indemnify any such person seeking indemnification in connection with a Proceeding (or part thereof) initiated by such person only if such Proceeding (or part thereof) was authorized by the Board of Directors. The Corporation may pay the expenses incurred in defending any such Proceeding in advance of its final disposition; any advance payments to be paid by the Corporation within 20 calendar days after the receipt by the Corporation of a statement or statements from the claimant requesting such advance or advances from time to time; provided, however, that, to the extent the DGCL requires, the payment of such expenses incurred by a Director or officer in such person’s capacity as a Director or officer (and not in any other capacity in which service was or is rendered by such person while a Director or officer, including, without limitation, service to an employee benefit plan) in advance of the final disposition of a Proceeding, shall be made only upon delivery to the Corporation of an undertaking, by or on behalf of such Director or officer, to repay all amounts so advanced if it shall ultimately be determined that such Director or officer is not entitled to be indemnified under this Section 7.02 or otherwise. The Corporation may, to the extent authorized from time to time by the Board of Directors, grant rights to indemnification, and rights to have the Corporation pay the expenses incurred in defending any Proceeding in advance of its final disposition, to any employee or agent of the Corporation to the fullest extent of the provisions of this Article VII with respect to the indemnification and advancement of expenses of Directors and officers of the Corporation.

(b) Right of Claimant to Bring Suit. If a claim under paragraph (a) of this Section 7.02 is not paid in full by the Corporation within 30 calendar days after a written claim has been received by the Corporation, the claimant may at any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim and, if successful in whole or in part, the claimant shall be entitled to be paid also the expense of prosecuting such claim. It shall be a defense to any such action (other than an action brought to enforce a claim for expenses incurred in defending any Proceeding in advance of its final disposition where the required undertaking, if any is required, has been tendered to the Corporation) that the claimant has not met the standard of conduct which

A-8

makes it permissible under the DGCL for the Corporation to indemnify the claimant for the amount claimed, but the burden of proving such defense shall be on the Corporation. Neither the failure of the Corporation (including its Board of Directors, independent legal counsel, or its stockholders) to have made a determination prior to the commencement of such action that indemnification of the claimant is proper in the circumstances because the claimant has met the applicable standard of conduct set forth in the DGCL, nor an actual determination by the Corporation (including its Board of Directors, independent legal counsel, or its stockholders) that the claimant has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that the claimant has not met the applicable standard of conduct.

(c) Non-Exclusivity of Rights. The right to indemnification and the payment of expenses incurred in defending a Proceeding in advance of its final disposition conferred in this Section 7.02 shall not be exclusive of any other right which any person may have or hereafter acquire under any statute, provision of this Restated Certificate of Incorporation (including any Certificate of Designation), By-law, agreement, vote of stockholders or disinterested Directors or otherwise. No repeal or modification of this Article VII shall in any way diminish or adversely affect the rights of any Director, officer, employee or agent of the Corporation hereunder in respect of any occurrence or matter arising prior to any such repeal or modification.

(d) Insurance. The Corporation may maintain insurance, at its expense, to protect itself and any Director, officer, employee or agent of the Corporation or another corporation, partnership, joint venture, trust or other enterprise against any such expense, liability or loss, whether or not the Corporation would have the power to indemnify such person against such expense, liability or loss under the DGCL.

(e) Severability. If any provision or provisions of this Article VII shall be held to be invalid, illegal or unenforceable for any reason whatsoever: (i) the validity, legality and enforceability of the remaining provisions of this Article VII (including, without limitation, each portion of any paragraph of this Article VII containing any such provision held to be invalid, illegal or unenforceable, that is not itself held to be invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby; and (ii) to the fullest extent possible, the provisions of this Article VII (including, without limitation, each such portion of any paragraph of this Article VII containing any such provision held to be invalid, illegal or unenforceable) shall be construed so as to give effect to the intent manifested by the provision held invalid, illegal or unenforceable.

B-2

the meeting and who complies with the notice procedures set forth in paragraph (a)(ii) of this Section 2.07.

(ii) For nominations or other business to be properly brought before an annual meeting by a stockholder pursuant to clause (C) of paragraph (a)(i) of this Section 2.07, the stockholder must have given timely notice thereof in writing to the Secretary of the Corporation and such other business must otherwise be a proper matter for stockholder action. To be timely, a stockholder’s notice shall be delivered to the Secretary of the Corporation at the principal executive offices of the Corporation not later than the close of business on the 90th calendar day nor earlier than the close of business on the 120th calendar day prior to the first anniversary of the preceding year’s annual meeting; provided, however, that in the event that the date of the annual meeting is more than 30 calendar days before or more than 60 calendar days after such anniversary date, notice by the stockholder to be timely must be so delivered not earlier than the close of business on the 120th calendar day prior to such annual meeting and not later than the close of business on the 90th calendar day prior to such annual meeting; provided, further, however, that in the event that less than 100 calendar days’ notice or prior public disclosure by the Corporation of the date of the meeting is given or made to stockholders, notice by the stockholder to be timely must be so received not later than the close of business on the 10th calendar day following the calendar day on which such notice of the date of the annual meeting was mailed or such public announcement was made by the Corporation, whichever first occurs. For purposes of determining whether a stockholder’s notice shall have been delivered in a timely manner for the annual meeting of stockholders in 2007, the first anniversary of the previous year’s meeting shall be deemed to be [ ], 2007. In no event shall the public announcement by the Corporation of an adjournment or postponement of an annual meeting commence a new time period for the giving of a stockholder’s notice as described above. Such stockholder’s notice shall set forth (A) as to each person whom the stockholder proposes to nominate for election or reelection as a Director all information relating to such person that is required to be disclosed in solicitations of proxies for election of Directors in an election contest, or is otherwise required, in each case pursuant to Regulation 14A under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and Rule 14a-11 (or any successor thereof) under the Exchange Act (including such person’s written consent to being named in the proxy statement as a nominee and to serving as a Director if elected); (B) as to any other business that the stockholder proposes to bring before the meeting, a brief description of the business desired to be brought before the meeting, the text of the proposal or business (including the text of any resolutions proposed for consideration and in the event that such business includes a proposal to amend these By-Laws, the language of the proposed amendment), the reasons for conducting such business at the meeting and any material interest in such business of such stockholder and the beneficial owner, if any, on whose behalf the proposal is made; and (C) as to the stockholder giving the notice and the beneficial owner, if any, on whose behalf the nomination or proposal is made (1) the name and address of such stockholder, as they appear on the Corporation’s books, and of such beneficial owner, (2) the class and number of shares of the Corporation which are owned beneficially and of record by such stockholder and such beneficial owner, (3) a representation that the stockholder is a holder of record of stock of the Corporation entitled to vote at such meeting and intends to appear in person or by proxy at the meeting to propose such business or nomination, and (4) a representation whether the stockholder or the beneficial owner, if any, intends or is part of a

B-3

group which intends (x) to deliver a proxy statement and/or form of proxy to holders of at least the percentage of the Corporation’s outstanding capital stock required to approve or adopt the proposal or elect the nominee and/or (y) otherwise to solicit proxies from stockholders in support of such proposal or nomination. The foregoing notice requirements shall be deemed satisfied by a stockholder if the stockholder has notified the Corporation of his or her intention to present a proposal at an annual meeting in compliance with Rule 14a-8 (or any successor thereof) under the Exchange Act and such stockholder’s proposal has been included in a proxy statement that has been prepared by the Corporation to solicit proxies for such annual meeting. The Corporation may require any proposed nominee to furnish such other information as it may reasonably require to determine the eligibility of such proposed nominee to serve as a Director.

(iii) Notwithstanding anything in the second sentence of paragraph (a)(ii) of this Section 2.07 to the contrary, in the event that the number of Directors to be elected to the Board of Directors is increased and there is no public announcement by the Corporation naming all of the nominees for Director or specifying the size of the increased Board of Directors at least 100 calendar days prior to the first anniversary of the preceding year’s annual meeting, a stockholder’s notice required by paragraph (a)(ii) of this Section 2.07 shall also be considered timely, but only with respect to nominees for any new positions created by such increase, if it shall be delivered to the Secretary at the principal executive offices of the Corporation not later than the close of business on the 10th calendar day following the day on which such public announcement is first made by the Corporation.

(b) Special Meetings of Stockholders. Only such business shall be conducted at a special meeting of stockholders as shall have been brought before the meeting pursuant to the Corporation’s notice of meeting under Section 2.04. Nominations of persons for election to the Board of Directors may be made at a special meeting of stockholders at which Directors are to be elected pursuant to the Corporation’s notice of meeting (i) by or at the direction of the Board of Directors, or (ii) provided that the Board of Directors has determined that Directors shall be elected at such meeting, by any stockholder of the Corporation who is a stockholder of record at the time he or she gave notice as provided in paragraph (a)(ii) of this Section 2.07, who shall be entitled to vote at the meeting and who complies with the notice procedures set forth in this paragraph (b) of Section 2.07. In the event the Corporation calls a special meeting of stockholders for the purpose of electing one or more Directors to the Board of Directors, any stockholder may nominate a person or persons (as the case may be) for election to such position(s) as specified in the Corporation’s notice of meeting pursuant to such clause (ii), if a notice by such stockholder meeting the requirements of paragraph (a)(ii) of this Section 2.07 shall be delivered to the Secretary at the principal executive offices of the Corporation not earlier than the close of business on the 120th calendar day prior to such special meeting and not later than the close of business on the 90th calendar day prior to such special meeting; provided, however, that in the event that less than 100 calendar days’ notice or prior public disclosure by the corporation of the date of the meeting is given or made to stockholders, notice by the stockholder to be timely must be so received not later than the close of business on the 10th calendar day following the calendar day on which notice of the date of the special meeting and of the nominees proposed by the Board of Directors to be elected at such meeting was mailed or such public announcement was made, whichever first occurs. In no event shall the public announcement

B-4

of an adjournment or postponement of a special meeting commence a new time period for the giving of a stockholder’s notice as described above.

(c) General. (i) Only such persons who are nominated in accordance with the procedures set forth in this Section 2.07 shall be eligible to serve as Directors and only such business shall be conducted at a meeting of stockholders as shall have been brought before the meeting in accordance with the procedures set forth in this Section 2.07. Except as otherwise provided by law, the Certificate of Incorporation or these By-Laws, the presiding officer shall have the power and duty to determine whether a nomination or any business proposed to be brought before the meeting was made or proposed, as the case may be, in accordance with the procedures set forth in this Section 2.07 (including whether the stockholder or beneficial owner, if any, on whose behalf the nomination or proposal is made solicited (or is part of a group which solicited) or did not so solicit, as the case may be, proxies in support of such stockholder’s nominee or proposal in compliance with such stockholder’s representation as required by clause (a)(ii)(C)(4) of this Section 2.07) and, if any proposed nomination or business is not in compliance with this Section 2.07, to declare that such defective proposal or nomination shall be disregarded. Notwithstanding the foregoing provisions of this Section 2.07, if the stockholder (or a qualified representative of the stockholder) does not appear at the annual or special meeting of stockholders of the Corporation to present a nomination or business, such nomination shall be disregarded and such proposed business shall not be transacted, notwithstanding that proxies in respect of such vote may have been received by the Corporation.

(ii) For purposes of this Section 2.07, “public announcement” shall mean disclosure in a press release reported by the Dow Jones News Service, Associated Press or comparable national news service or in a document publicly filed by the Corporation with the Securities and Exchange Commission pursuant to Section 13, 14 or 15 (d) of the Exchange Act.

(iii) Notwithstanding the foregoing provisions of this Section 2.07, a stockholder shall also comply with all applicable requirements of the Exchange Act and the rules and regulations thereunder with respect to the matters set forth in this Section 2.07. Nothing in this Section 2.07 shall be deemed to affect any rights (a) of stockholders to request inclusion of proposals in the Corporation’s proxy statement pursuant to Rule 14a-8 under the Exchange Act, or (b) of the holders of any series of Preferred Stock or any class or series of stock having a preference over the Common Stock as to dividends or upon liquidation, dissolution or winding up of the Corporation to elect Directors under the Certificate of Incorporation or any resolution or resolutions providing for the issue of such class or series of stock adopted by the Board of Directors.

SECTION 2.08. Procedure for Election of Directors; Required Vote. Election of Directors at all meetings of the stockholders at which Directors are to be elected shall be by ballot, and, subject to the rights of the holders of any series of Preferred Stock or any class or series of stock having a preference over the Common Stock as to dividends or upon liquidation, dissolution or winding up to elect Directors under the Certificate of Incorporation or any resolution or resolutions providing for the issue of such class or series of stock adopted by the Board of Directors, a plurality of the votes cast thereat shall be the vote

required to elect Directors. Except as otherwise provided by law, the Certificate of Incorporation (including any Certificate of Designation (as defined in the Certificate of Incorporation)), applicable stock exchange rules or other rules and regulations applicable to the Corporation or these By-Laws, in all matters other than the election of Directors, the affirmative vote of a majority of the voting power of the shares present in person or represented by proxy at the meeting and entitled to vote on the matter shall be the act of the stockholders.

SECTION 2.09. Inspectors of Elections; Opening and Closing the Polls. (a) The Board of Directors by resolution shall appoint, or shall authorize an officer of the Corporation to appoint, one or more inspectors, which inspector or inspectors may include individuals who serve the Corporation in other capacities, including, without limitation, as officers, employees, agents or representatives, to act at any meeting of stockholders and make a written report thereof. One or more persons may be designated as alternate inspector(s) to replace any inspector who fails to act. If no inspector or alternate has been appointed to act or is able to act at a meeting of stockholders, the presiding officer shall appoint one or more inspectors to act at the meeting. Each inspector, before discharging such person’s duties, shall take and sign an oath faithfully to execute the duties of inspector with strict impartiality and according to the best of such person’s ability. The inspector(s) shall have the duties prescribed by law.

(b) The date and time of the opening and the closing of the polls for each matter upon which the stockholders will vote at a meeting shall be announced at the meeting by the officer presiding over the meeting.

Subject to applicable law, at the time of such surrender of any such certificate (or, in the case of clause (ii) below, at the appropriate payment date), there shall be paid to the holder of the certificates representing Domtar Common Shares, without interest, (i) the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to the Exchangeable Shares or shares of Spinco Common Stock, as the case may be, to which such holder is entitled pursuant hereto and (ii) on the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to surrender and a payment date subsequent to surrender payable with respect to such Exchangeable Shares or shares of Spinco Common Stock, as the case may be.

4.3 Lost Certificates

In the event any certificate which immediately prior to the Effective Time represented one or more outstanding Domtar Common Shares that were exchanged pursuant to section 2.2

D-13

When authorizing such payment in exchange for any lost, stolen or destroyed certificate, the person to whom certificates representing Exchangeable Shares or shares of Spinco Common Stock are to be issued shall, as a condition precedent to the issuance thereof, give a bond satisfactory to Newco Canada Exchangeco, Newco Canada and Spinco and their respective transfer agents in such sum as Newco Canada Exchangeco, Newco Canada or Spinco may direct or otherwise indemnify Newco, Newco Canada and Spinco in a manner satisfactory to Newco Canada Exchangeco, Newco Canada and Spinco against any claim that may be made against Newco Canada Exchangeco, Newco Canada or Spinco with respect to the certificate alleged to have been lost, stolen or destroyed.

On such date, the Exchangeable Shares or the shares of Spinco Common Stock to which the former holder of the certificate referred to in the preceding sentence was ultimately entitled shall be deemed to have been surrendered for no consideration to Newco Canada Exchangeco or Newco Canada, as the case may be, together with all entitlements to dividends, distributions and interest in respect thereof held for such former holder.

4.5 No Liability

None of the parties to the Transaction Agreement or the Exchange Agent shall be liable to any person in respect of any shares of Spinco Common Stock or any Exchangeable Shares (or dividends or distributions with respect thereto) or proceeds from a sale pursuant to section 4.1 that are delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. If any claim for the Arrangement Consideration (as defined in the Transaction Agreement) or any dividends has not been made prior to five years after the Effective Time (or immediately prior to such earlier date on which the Arrangement Consideration or dividends in respect of such shares would otherwise escheat to or become the property of any Government Entity), any such shares, cash, dividends or distributions shall, to the extent permitted by applicable law, become the property of Newco Canada or Newco Canada Exchangeco, as applicable, free and clear of all claims or interest of any person previously entitled thereto.

4.6 Withholding Rights

Newco Canada and Newco Canada Exchangeco shall be entitled, and may instruct the Exchange Agent or the Transfer Agent, as the case may be, to deduct and withhold from any dividend or consideration otherwise payable to any holder of Domtar Common Shares, Class B Common Shares, shares of Spinco Common Stock or Exchangeable Shares such amounts as Newco Canada or Newco Canada Exchangeco is required or permitted to deduct and withhold

D-14

with respect to such payments under (i) the ITA, the United States Internal Revenue Code of 1986 or any provision of provincial, state, local or foreign tax law, in each case, as amended or succeeded or (ii) required or permitted in order to comply with Section 116 of the ITA or any corresponding provisions of provincial law.

To the extent that the amount so required or permitted to be deducted or withheld from any payment to a holder exceeds the cash portion of the consideration otherwise payable to the holder, Newco Canada Exchangeco, Newco Canada and the Exchange Agent are hereby authorized to sell or otherwise dispose of, subject to applicable law, such portion of the consideration as is necessary to provide sufficient funds to Newco Canada Exchangeco, Newco Canada or the Exchange Agent, as the case may be, to enable it to comply with such deduction or withholding requirement and Newco Canada Exchangeco, Newco Canada or the Exchange Agent shall notify the holder thereof and remit any unapplied balance of the net proceeds of such sale.

ARTICLE 5

CERTAIN RIGHTS OF NEWCO CANADA TO ACQUIRE
EXCHANGEABLE SHARES

5.1 Newco Canada Liquidation Call Right

	(a)		Newco Canada shall have the overriding right (the “Liquidation Call Right”), in the event of and notwithstanding the proposed liquidation, dissolution or winding-up of Newco Canada Exchangeco pursuant to Article 3.5 of the Exchangeable Share Provisions, to purchase from all but not less than all of the holders of Exchangeable Shares (other than any holder of Exchangeable Shares which is a subsidiary of Spinco) on the Liquidation Date all but not less than all of the Exchangeable Shares held by each such holder on payment by Newco Canada of an amount per Exchangeable Share (the “Liquidation Call Purchase Price”) equal to the Current Market Price of a share of Spinco Common Stock on the last Business Day prior to the Liquidation Date, which shall be satisfied in full by Newco Canada causing to be delivered to such holder one share of Spinco Common Stock, plus any Dividend Amount. In the event of the exercise of the Liquidation Call Right by Newco Canada, each holder shall be obligated to sell all the Exchangeable Shares held by the holder to Newco Canada on the Liquidation Date on payment by Newco Canada to the holder of the Liquidation Call Purchase Price for each such share, and Newco Canada Exchangeco shall have no obligation to pay any Liquidation Amount to the holders of such shares so purchased by Newco Canada.

	(b)		To exercise the Liquidation Call Right, Newco Canada must notify Newco Canada Exchangeco’s transfer agent (the “Transfer Agent”), as agent for the holders of Exchangeable Shares, and Newco Canada Exchangeco of Newco Canada’s intention to exercise such right at least 45 days before the Liquidation Date in the case of a voluntary liquidation, dissolution or winding up of Newco Canada Exchangeco and at least five Business Days before the Liquidation Date in the case of an involuntary liquidation, dissolution or winding up of Newco

D-15

			Canada Exchangeco. The Transfer Agent will notify the holders of Exchangeable Shares as to whether or not Newco Canada has exercised the Liquidation Call Right forthwith after the expiry of the period during which the same may be exercised by Newco Canada. If Newco Canada exercises the Liquidation Call Right, then on the Liquidation Date Newco Canada will purchase and the holders will sell all of the Exchangeable Shares then outstanding for a price per share equal to the Liquidation Call Purchase Price.

	(c)		For the purposes of completing the purchase of the Exchangeable Shares pursuant to the Liquidation Call Right, Newco Canada shall deposit with the Transfer Agent, on or before the Liquidation Date, one single certificate representing the aggregate number of shares of Spinco Common Stock deliverable by Newco Canada and a cheque or cheques of Newco Canada payable at par at any branch of the bankers of Newco Canada representing the aggregate Dividend Amount, if any, in payment of the total Liquidation Call Purchase Price, less any amounts withheld pursuant to section 4.6. Provided that Newco Canada has complied with the immediately preceding sentence, on and after the Liquidation Date the rights of each holder of Exchangeable Shares will be limited to receiving such holder’s proportionate part of the total Liquidation Call Purchase Price payable by Newco Canada upon presentation and surrender by the holder of certificates, if any, representing the Exchangeable Shares held by such holder together with such other documents and instruments as may be required to effect a transfer of Exchangeable Shares and such additional documents and instruments as the Transfer Agent may reasonably require and the holder shall on and after the Liquidation Date be considered and deemed for all purposes to be the holder of the shares of Spinco Common Stock to which it is entitled. Upon surrender to the Transfer Agent of a certificate or certificates, if any, representing Exchangeable Shares, together with such other documents and instruments as may be required to effect a transfer of Exchangeable Shares and such additional documents and instruments as the Transfer Agent may reasonably require, such holder shall be entitled to receive in exchange therefor, and the Transfer Agent on behalf of Newco Canada shall deliver to such holder the shares of Spinco Common Stock to which the holder is entitled (either in the form of a certificate or, in whole or in part, in book-entry form through the direct registration system) and a cheque or cheques of Newco Canada payable at par at any branch of the bankers of Newco Canada in payment of the remaining portion, if any, of the total Liquidation Call Purchase Price, less any amounts withheld pursuant to section 4.6. If Newco Canada does not exercise the Liquidation Call Right in the manner described above, then on the Liquidation Date the holders of the Exchangeable Shares will be entitled to receive in exchange therefor the Liquidation Amount otherwise payable by Newco Canada Exchangeco in connection with the liquidation, dissolution or winding-up of Newco Canada Exchangeco pursuant to Article 3.5 of the Exchangeable Share Provisions.

5.2 Newco Canada Redemption Call Right

In addition to Newco Canada’s rights contained in the Exchangeable Share Provisions, including, without limitation, the Retraction Call Right (as defined in the Exchangeable Share

D-16

Provisions), Newco Canada shall have the following rights in respect of the Exchangeable Shares:

	(a)		Newco Canada shall have the overriding right (the “Redemption Call Right”), notwithstanding the proposed redemption of the Exchangeable Shares by Newco Canada Exchangeco pursuant to Article 3.7 of the Exchangeable Share Provisions, to purchase from all but not less than all of the holders of Exchangeable Shares (other than any holder of Exchangeable Shares which is a subsidiary of Spinco) on the Redemption Date all but not less than all of the Exchangeable Shares held by each such holder on payment by Newco Canada to each holder of an amount per Exchangeable Share (the “Redemption Call Purchase Price”) equal to the Current Market Price of a share of Spinco Common Stock on the last Business Day prior to the Redemption Date, which shall be satisfied in full by Newco Canada causing to be delivered to such holder one share of Spinco Common Stock, plus the Dividend Amount. In the event of the exercise of the Redemption Call Right by Newco Canada, each holder shall be obligated to sell all the Exchangeable Shares held by the holder to Newco Canada on the Redemption Date on payment by Newco Canada to the holder of the Redemption Call Purchase Price for each such share, and Newco Canada Exchangeco shall have no obligation to redeem, or to pay any Dividend Amount in respect of, such shares so purchased by Newco Canada.

	(b)		To exercise the Redemption Call Right, Newco Canada must notify the Transfer Agent, as agent for the holders of Exchangeable Shares, and Newco Canada Exchangeco of Newco Canada’s intention to exercise such right at least 60 days before the Redemption Date, except in the case of a redemption occurring as a result of a Spinco Control Transaction, an Exchangeable Share Voting Event or an Exempt Exchangeable Share Voting Event (each as defined in the Exchangeable Share Provisions), in which case Newco Canada shall so notify the Transfer Agent and Newco Canada Exchangeco on or before the Redemption Date. The Transfer Agent will notify the holders of the Exchangeable Shares as to whether or not Newco Canada has exercised the Redemption Call Right forthwith after the expiry of the period during which the same may be exercised by Newco Canada. If Newco Canada exercises the Redemption Call Right, on the Redemption Date Newco Canada will purchase and the holders will sell all of the Exchangeable Shares then outstanding for a price per share equal to the Redemption Call Purchase Price.

	(c)		For the purposes of completing the purchase of the Exchangeable Shares pursuant to the Redemption Call Right, Newco Canada shall deposit with the Transfer Agent, on or before the Redemption Date, one single certificate representing the aggregate number of shares of Spinco Common Stock deliverable by Newco Canada and a cheque or cheques of Newco Canada payable at par at any branch of the bankers of Newco Canada representing the aggregate Dividend Amount, if any, in payment of the total Redemption Call Purchase Price, less any amounts withheld pursuant to section 4.6. Provided that Newco Canada has complied with the immediately preceding sentence, on and after the Redemption Date the rights of each holder of Exchangeable Shares will be limited to receiving such holder’s proportionate part of the total Redemption Call Purchase Price payable by Newco

D-17

Canada upon presentation and surrender by the holder of certificates, if any, representing the Exchangeable Shares held by such holder together with such other documents and instruments as may be required to effect a transfer of Exchangeable Shares and such additional document and instruments as the Transfer Agent may reasonably require and the holder shall on and after the Redemption Date be considered and deemed for all purposes to be the holder of the shares of Spinco Common Stock to which it is entitled. Upon surrender to the Transfer Agent of a certificate or certificates, if any, representing Exchangeable Shares, together with such other documents and instruments as may be required to effect a transfer of Exchangeable Shares and such additional documents and instruments as the Transfer Agent may reasonably require, such holder shall be entitled to receive in exchange therefor, and the Transfer Agent on behalf of Newco Canada shall deliver to such holder, the shares of Spinco Common Stock to which the holder is entitled (either in the form of a certificate or, in whole or in part, in book-entry form through the direct registration system) and a cheque or cheques of Newco Canada payable at par at any branch of the bankers of Newco Canada in payment of the remaining portion, if any, of the total Redemption Call Purchase Price, less any amounts withheld pursuant to section 4.6. If Newco Canada does not exercise the Redemption Call Right in the manner described above, then on the Redemption Date the holders of the Exchangeable Shares will be entitled to receive in exchange therefor the redemption price otherwise payable by Newco Canada Exchangeco in connection with the redemption of the Exchangeable Shares pursuant to Article 3.7 of the Exchangeable Share Provisions.

5.3 Fractional Shares

As soon as practicable after any exchange by a holder of any Exchangeable Shares pursuant to this Article 5, Newco Canada shall direct the Transfer Agent (i) to determine the number, if any, of whole and fractional shares of Spinco Common Stock allocable to such holder, (ii) to aggregate all such fractional shares and sell the whole shares obtained thereby at the direction of the Corporation either in open market transactions or otherwise, in each case at then prevailing trading prices, and (iii) to cause to be distributed to such holder in lieu of any fractional share, such holder’s rateable share of the proceeds of such sale, after making appropriate deductions of the amount required to be withheld for tax purposes and after deducting an amount equal to all brokerage charges, commissions and transfer taxes attributed to such sale.

The notice of redemption shall set out the redemption price and the time and date on which redemption is to take place and, if only part of the shares held by the shareholder to whom it is addressed is to be redeemed, the number thereof so to be redeemed.

If only a part of the shares represented by any certificate are to be redeemed, a new certificate for the balance shall be issued at the expense of the Corporation. Subject to the provisions of section 2.6.3, on and after the date specified for redemption in a notice of redemption, the Preference Shares called for redemption shall cease to be entitled to dividends and the holders thereof shall not be entitled to exercise any of the rights of shareholders in respect thereof unless payment of the redemption price shall not be made upon presentation of certificates in accordance with the foregoing provisions, in which case the rights of the shareholders shall remain unaffected.

Any interest earned on any such deposit shall belong to the Corporation. Redemption moneys that are represented by a cheque which has not been presented to the Corporation’s bankers for payment or that otherwise remain unclaimed (including moneys held on deposit to a special account as provided for above) for a period of six years from the date specified for redemption shall be forfeited to the Corporation.

2.6.4 In the event that only part of the Preference Shares is at any time to be redeemed, the shares so to be redeemed shall be selected pro rata (disregarding fractions) from among the holders of record thereof as at the date of the notice of redemption or in such other manner as the Board of Directors in its sole discretion may deem equitable.

3.6.2 Subject to the exercise by Newco Canada of the Retraction Call Right, upon receipt by the Corporation or the Transfer Agent in the manner specified in section 3.6.1 hereof of a certificate or certificates, if any, representing the number of Retracted Shares, together with a Retraction Request and the other documents and instruments required in accordance with section 3.6.1, and provided that the Retraction Request is not revoked by the holder in the manner specified in section 3.6.7, the Corporation shall redeem the Retracted Shares effective at the close of business on the Retraction Date and shall cause to be delivered to such holder the total Retraction Price. If only a part of the Exchangeable Shares is redeemed (or purchased by Newco Canada pursuant to the Retraction Call Right), the holder thereof shall receive at the expense of the Corporation (either in the form of a certificate, or in book-entry form through the direct registration system) the balance of such Exchangeable Shares.

3.6.3 Upon receipt by the Corporation of a Retraction Request, the Corporation shall immediately notify Newco Canada thereof and shall provide to Newco Canada a copy of the Retraction Request. In order to exercise the Retraction Call Right, Newco Canada must notify the Corporation of its determination to do so (the “Newco Canada Call Notice”) within five Business Days of notification to Newco Canada by the Corporation of the receipt by the Corporation of the Retraction Request. If Newco Canada does not so notify the Corporation within such five Business Day period, the Corporation will notify the holder as soon as possible thereafter that Newco Canada will not exercise the Retraction Call Right. If Newco Canada

D-34

delivers the Newco Canada Call Notice within such five Business Day period, and provided that the Retraction Request is not revoked by the holder in the manner specified in section 3.6.7, the Retraction Request shall thereupon be considered only to be an offer by the holder to sell the Retracted Shares to Newco Canada in accordance with the Retraction Call Right. In such event, the Corporation shall not redeem the Retracted Shares and Newco Canada shall purchase from such holder and such holder shall sell to Newco Canada on the Retraction Date the Retracted Shares for a purchase price (the “Purchase Price”) per share equal to the Retraction Price per share, plus on the designated payment date therefor, to the extent not paid by the Corporation on the designated payment date therefor, any Dividend Amount. To the extent that Newco Canada pays the Dividend Amount in respect of the Retracted Shares, the Corporation shall no longer be obligated to pay any declared and unpaid dividends on such Retracted Shares. Provided that Newco Canada has complied with section 3.6.4, the closing of the purchase and sale of the Retracted Shares pursuant to the Retraction Call Right shall be deemed to have occurred as at the close of business on the Retraction Date and, for greater certainty, no redemption by the Corporation of such Retracted Shares shall take place on the Retraction Date. In the event that Newco Canada does not deliver a Newco Canada Call Notice within such five Business Day period, and provided that the Retraction Request is not revoked by the holder in the manner specified in section 3.6.7, the Corporation shall redeem the Retracted Shares on the Retraction Date and in the manner otherwise contemplated in this Article 3.6.

3.6.4 The Corporation or Newco Canada, as the case may be, shall deliver or cause the Transfer Agent to deliver to the relevant holder, at the address of the holder recorded in the securities register of the Corporation for the Exchangeable Shares or at the address specified in the holder’s Retraction Request or by holding for pick-up by the holder at the registered office of the Corporation or at any office of the Transfer Agent as may be specified by the Corporation by notice to the holders of Exchangeable Shares, the shares of Spinco Common Stock to which the holder is entitled (which shares shall be duly issued as fully paid and non-assessable and shall be free and clear of any lien, claim or encumbrance), either in the form of certificates representing the shares of Spinco Common Stock registered in the name of the holder or in such other name as the holder may request or, in whole or in part, in book-entry form through the direct registration system, and, if applicable and on or before the payment date therefor, a cheque payable at par at any branch of the bankers of the Corporation or Newco Canada, as applicable, representing the aggregate Dividend Amount, in payment of the total Retraction Price or the total Purchase Price, as the case may be, in each case, less any amounts withheld on account of tax required to be deducted and withheld therefrom, and such delivery of such shares of Spinco Common Stock and cheques on behalf of the Corporation or by Newco Canada, as the case may be, or by the Transfer Agent shall be deemed to be payment of and shall satisfy and discharge all liability for the total Retraction Price or total Purchase Price, as the case may be, to the extent that the same is represented by such shares of Spinco Common Stock and cheques (plus any tax deducted and withheld therefrom and remitted to the proper tax authority).

3.6.5 On and after the close of business on the Retraction Date, the holder of the Retracted Shares shall cease to be a holder of such Retracted Shares and shall not be entitled to exercise any of the rights of a holder in respect thereof, other than the right to receive his proportionate part of the total Retraction Price or total Purchase Price, as the case may be, unless upon presentation and surrender of the documents and instruments in accordance with the foregoing provisions, payment of the total Retraction Price or the total Purchase Price, as the case may be, shall not be made as provided in section 3.6.4, in which case the rights of such holder shall remain unaffected until the total Retraction Price or the total Purchase Price, as the

D-35

case may be, has been paid in the manner hereinbefore provided. On and after the close of business on the Retraction Date, provided that presentation and surrender of the documents and instruments in accordance with the foregoing provisions and payment of the total Retraction Price or the total Purchase Price, as the case may be, has been made in accordance with the foregoing provisions, the holder of the Retracted Shares so redeemed by the Corporation or purchased by Newco Canada shall thereafter be considered and deemed for all purposes to be a holder of the shares of Spinco Common Stock delivered to it.

3.6.6 Notwithstanding any other provision of this Article 3.6, the Corporation shall not be obligated to redeem Retracted Shares specified by a holder in a Retraction Request to the extent that such redemption of Retracted Shares would be contrary to solvency requirements or other provisions of applicable law. If the Corporation believes that on any Retraction Date it would not be permitted by any of such provisions to redeem the Retracted Shares tendered for redemption on such date, and provided that Newco Canada shall not have exercised the Retraction Call Right with respect to the Retracted Shares, the Corporation shall only be obligated to redeem Retracted Shares specified by a holder in a Retraction Request to the extent of the maximum number that may be so redeemed (rounded down to a whole number of shares) as would not be contrary to such provisions and shall notify the holder and the Trustee at least two Business Days prior to the Retraction Date as to the number of Retracted Shares which will not be redeemed by the Corporation. In any case in which the redemption by the Corporation of Retracted Shares would be contrary to solvency requirements or other provisions of applicable law, the Corporation shall redeem Retracted Shares in accordance with section 3.6.2 of these share provisions on a pro rata basis and the holder of Retracted Shares shall receive at the Corporation’s expense (either in the form of a certificate or in book-entry form through the direct registration system) the Retracted Shares not redeemed by the Corporation pursuant to section 3.6.2. Provided that the Retraction Request is not revoked by the holder in the manner specified in section 3.6.7, the holder of any such Retracted Shares not redeemed by the Corporation pursuant to section 3.6.2 of these share provisions as a result of solvency requirements or other provisions of applicable law shall be deemed by giving the Retraction Request to require Newco Canada, to purchase such Retracted Shares from such holder on the Retraction Date or as soon as practicable thereafter on payment by Newco Canada as the case may be, to such holder of the Purchase Price for each such Retracted Share, all as more specifically provided in the Voting and Exchange Trust Agreement.

3.6.7 A holder of Retracted Shares may, by notice in writing given by the holder to the Corporation before the close of business on the Business Day immediately preceding the Retraction Date, withdraw its Retraction Request, in which event such Retraction Request shall be null and void and, for greater certainty, the revocable offer constituted by the Retraction Request to sell the Retracted Shares to Newco Canada shall be deemed to have been revoked.

ARTICLE 3.7
REDEMPTION OF EXCHANGEABLE SHARES BY THE CORPORATION

3.7.1 Subject to applicable law, and provided Newco Canada has not exercised the Redemption Call Right, the Corporation shall on the Redemption Date redeem all but not less than all of the then outstanding Exchangeable Shares for an amount per Exchangeable Share equal to the Current Market Price of a share of Spinco Common Stock on the last Business Day prior to the Redemption Date (the “Redemption Price”), which shall be satisfied in full by the Corporation causing to be delivered to each holder of Exchangeable Shares, for each

D-36

Exchangeable Share held by such holder, one share of Spinco Common Stock, together with the full amount of all declared and unpaid dividends on each such Exchangeable Share held by such holder on any dividend record date which occurred prior to the Redemption Date.

3.7.2 In any case of a redemption of Exchangeable Shares under this Article 3.7, the Corporation shall, at least 60 days before the Redemption Date (other than a Redemption Date established in connection with a Spinco Control Transaction, an Exchangeable Share Voting Event or an Exempt Exchangeable Share Voting Event), send or cause to be sent to each holder of Exchangeable Shares a notice in writing of the redemption by the Corporation or the purchase by Newco Canada under the Redemption Call Right, as the case may be, of the Exchangeable Shares held by such holder. In the case of a Redemption Date established in connection with a Spinco Control Transaction, an Exchangeable Share Voting Event or an Exempt Exchangeable Share Voting Event, the written notice of redemption by the Corporation or the purchase by Newco Canada under the Redemption Call Right will be sent on or before the Redemption Date, on as many days prior written notice as may be determined by the Board of Directors of the Corporation to be reasonably practicable in the circumstances. In any such case, such notice shall set out the formula for determining the Redemption Price or the Redemption Call Purchase Price, as the case may be, the Redemption Date and, if applicable, particulars of the Redemption Call Right.

3.7.3 On or after the Redemption Date and subject to the exercise by Newco Canada of the Redemption Call Right, the Corporation shall cause to be delivered to the holders of the Exchangeable Shares to be redeemed the Redemption Price for each such Exchangeable Share, if any, together with the full amount of all declared and unpaid dividends on each such Exchangeable Share held by such holder on any dividend record date which occurred prior to the Redemption Date, upon presentation and surrender at the registered office of the Corporation or at any office of the Transfer Agent as may be specified by the Corporation in such notice of the certificates representing such Exchangeable Shares, if any, together with such other documents and instruments as may be required to effect a transfer of Exchangeable Shares and such additional documents and instruments as the Transfer Agent and the Corporation may reasonably require. Payment of the total Redemption Price for such Exchangeable Shares, together with payment of such dividends, shall be made by delivery to each holder, at the address of the holder recorded in the securities register of the Corporation or by holding for pick-up by the holder at the registered office of the Corporation or at any office of the Transfer Agent as may be specified by the Corporation in such notice, on behalf of the Corporation, of the shares of Spinco Common Stock to which the holder is entitled (which shares shall be duly issued as fully paid and non-assessable and shall be free and clear of any lien, claim or encumbrance), either in the form of certificates representing the shares of Spinco Common Stock or, in whole or in part, in book-entry form through the direct registration system, and, if applicable, a cheque of the Corporation payable at par at any branch of the bankers of the Corporation in payment of any such dividends, in each case, less any amounts withheld on account of tax required to be deducted and withheld therefrom. On and after the Redemption Date, the holders of the Exchangeable Shares called for redemption shall cease to be holders of such Exchangeable Shares and shall not be entitled to exercise any of the rights of holders in respect thereof, other than the right to receive their proportionate part of the total Redemption Price and any such dividends, unless payment of the total Redemption Price and any such dividends for such Exchangeable Shares shall not be made upon presentation and surrender of the documents and instruments required in accordance with the foregoing provisions, in which case the rights of the holders shall remain unaffected until the total Redemption Price and any such dividends have been paid in the manner hereinbefore

D-37

provided. The Corporation shall have the right at any time after the sending of notice of its intention to redeem the Exchangeable Shares as aforesaid to deposit or cause to be deposited the total Redemption Price for and the full amount of such dividends on (except as otherwise provided in this section 3.7.3) the Exchangeable Shares so called for redemption, in a custodial account with any chartered bank or trust company in Canada named in such notice, less any amounts withheld on account of tax required to be deducted and withheld therefrom. Upon the later of such deposit being made and the Redemption Date, the Exchangeable Shares in respect whereof such deposit shall have been made shall be redeemed and the rights of the holders thereof after such deposit or Redemption Date, as the case may be, shall be limited to receiving their proportionate part of the total Redemption Price and such dividends for such Exchangeable Shares so called for redemption, against presentation and surrender of the documents and instruments required in accordance with the foregoing provisions. Upon such payment or deposit of the total Redemption Price and the full amount of such dividends, the holders of the Exchangeable Shares shall thereafter be considered and deemed for all purposes to be holders of the shares of Spinco Common Stock delivered to them or the custodian on their behalf.

ARTICLE 3.8
PURCHASE FOR CANCELLATION

3.8.1 Subject to applicable law and notwithstanding section 3.8.2, the Corporation may at any time and from time to time purchase for cancellation all or any part of the Exchangeable Shares by private agreement with any holder of Exchangeable Shares for consideration consisting of Common Shares.

3.8.2 Subject to applicable law, the Corporation may at any time and from time to time purchase for cancellation all or any part of the outstanding Exchangeable Shares at any price by tender to all the holders of record of Exchangeable Shares then outstanding or through the facilities of any stock exchange on which the Exchangeable Shares are listed or quoted at any price per share. If in response to an invitation for tenders under the provisions of this section 3.8.2, more Exchangeable Shares are tendered at a price or prices acceptable to the Corporation than the Corporation is prepared to purchase, the Exchangeable Shares to be purchased by the Corporation shall be purchased as nearly as may be pro rata according to the number of shares tendered by each holder who submits a tender to the Corporation, provided that when shares are tendered at different prices, the pro rating shall be effected (disregarding fractions) only with respect to the shares tendered at the price at which more shares were tendered than the Corporation is prepared to purchase after the Corporation has purchased all the shares tendered at lower prices. If part only of the Exchangeable Shares shall be purchased, the holder thereof shall receive at the expense of the Corporation (either in the form of a certificate or in book-entry form through the direct registration system) the balance of such shares.

ARTICLE 3.9
VOTING RIGHTS

3.10.2 Any approval given by the holders of the Exchangeable Shares to add to, change or remove any right, privilege, restriction or condition attaching to the Exchangeable Shares or any other matter requiring the approval or consent of the holders of the Exchangeable Shares shall be deemed to have been sufficiently given if it shall have been given in accordance with applicable law subject to a minimum requirement that such approval be evidenced by a resolution passed by not less than two-thirds of the votes cast on such resolution at a meeting of holders of Exchangeable Shares duly called and held at which the holders of at least 25% of the outstanding Exchangeable Shares at that time are present or represented by proxy; provided that if at any such meeting the holders of at least 25% of the outstanding Exchangeable Shares at that time are not present or represented by proxy within one-half hour after the time appointed for such meeting, then the meeting shall be adjourned to such date not less than five days thereafter and to such time and place as may be designated by the Chairman of such meeting. At such adjourned meeting the holders of Exchangeable Shares present or represented by proxy thereat may transact the business for which the meeting was originally called and a resolution passed thereat by the affirmative vote of not less than two-thirds of the votes cast on such resolution at such meeting shall constitute the approval or consent of the holders of the Exchangeable Shares.

The Support Agreement further provides, in part, that the aforesaid provisions of the Support Agreement shall not be changed without the approval of the holders of the Exchangeable Shares given in accordance with section 3.10.2 of these share provisions.

TERM AND PROVISION OF SERVICES

2.1

Subject to Article 11, the term of this Agreement shall be for the Transition Period. The term for each Service is specified on the applicable Schedule hereto setting forth the terms and conditions for such Service. It is understood by the Parties that the scope of the services and cost estimates described in the schedules hereto do not include

E-4

Newco facilities at Ear Falls, Ontario, and Big River, Saskatchewan and operations related to the Forest Licenses (as defined in the Contribution and Distribution Agreement). The Service Provider agrees to provide Services for the Ear Falls, Big River and operations related to the Forest Licenses at fully allocated cost on the terms specified herein.

	2.2		During the Transition Period, but subject to Article 11 and the provisions set forth in this Agreement, the Service Provider shall provide the Services to the Service Recipient.

	2.3		The Service Provider shall provide, or cause to be provided, to the Service Recipient Services that are of substantially the same nature and quality that Weyerhaeuser and Weyerhaeuser Canada provided for the Newco Business during the twelve-month period prior to the Effective Time (and which shall be of substantially the same nature and quality that Weyerhaeuser and Weyerhaeuser Canada provide to themselves), at substantially the same priority levels that such Services have been accorded during such twelve-month period. The quantity of a particular Service provided by the Service Provider shall be the quantity identified for such Service in the applicable Schedule to this Agreement.

	2.4		The Service Provider shall not be obligated to perform services other than the Services described in the Schedules hereto. The Service Recipient may, from time to time, request that the Service Provider provide additional services during the Transition Period relating to Government legislated change, customer requirements, shipping/custom changes, functional enhancements, interface development or changes or converting to another platform or application (“Requested Services”). The Service Provider shall submit to the Service Recipient a written proposal to provide such Requested Services itself or through a third party setting forth each Requested Service to be performed, the time period for performance of such Requested Service and the amounts to be charged for performance of such Requested Service, which amounts shall be based on the Service Provider’s fully allocated cost including the fees of any third party provider.

	2.5		The Service Provider shall not be obligated to perform services other than the Services described in the Schedules hereto. The Service Recipient may, from time to time, request that the Service Provider provide additional services during the Transaction Period (“Additional Services”). The Service Provider shall consider each request for Additional Services in good faith, and if the Service Provider determines that it is prepared to provide the Service Recipient with all or a portion of the Additional Services identified in the request, it shall submit to the Service Recipient a written proposal to provide such Additional Services itself or through a third party setting forth each Additional Service to be performed, the time period for performance of such Additional Service, and the amounts to be charged for performance of such Additional Service, which amounts shall be based on the Service Provider’s fully allocated cost including the fees of any third party provider.

E-5

	2.6		Weyerhaeuser and Weyerhaeuser Canada may use third parties to provide some or all of the Services to the extent they use such third parties themselves with respect to the provision of such services for their own businesses. In addition, Weyerhaeuser and Weyerhaeuser Canada may provide to Service Recipient third party proposals for the provision of Services provided by Weyerhaeuser and Weyerhaeuser Canada hereunder and Service Recipient agrees to consider such proposals in good faith. The Service Provider shall use its reasonable best efforts to obtain the consent, where necessary, of any relevant third party provider of the Services to have such Services be provided to the Service Recipient. If such consent cannot be obtained, the Service Provider shall arrange for alternative methods of delivering the Service for which it is responsible hereunder. The Service Recipient will cooperate with and assist Weyerhaeuser and Weyerhaeuser Canada to obtain such consents; provided that nothing in this Section 2.6 shall require the Service Recipient to pay any consideration for obtaining any necessary consents or such alternative methods greater than the cost for such Service specified on the applicable Schedules or require Weyerhaeuser and Weyerhaeuser Canada to pay any consideration for obtaining any necessary consents which is not reimbursed by Service Recipient pursuant to this Agreement. Weyerhaeuser and Weyerhaeuser Canada agree that to the extent such third party Services are provided to Service Recipient pursuant to contracts between Weyerhaeuser and Weyerhaeuser Canada and the third party service provided, Weyerhaeuser and Weyerhaeuser Canada will enforce rights against any such third parties relating to the Services to the extent they would otherwise enforce such rights on behalf of themselves under similar circumstances relating to similar matters.

	2.7		In the event of any breach of this Article 2 by the Service Provider with respect to any Service and provided that the Service Recipient is not in breach of its obligations under Articles 3 and 4, the Service Provider shall, at the Service Recipient’s request, without the payment of any further fees by the Service Recipient, correct or cause to be corrected such error or defect or reperform or cause to be reperformed such Service, as promptly as practicable, and cause such Service to be provided thereafter in conformity with the standard set forth in Section 2.3.

	2.8		The Service Provider shall at all times maintain contingency plans in place to reasonably address disruptions in the Services. If a disruption of any Service occurs, the Service Provider shall use the same standard of care it uses to operate, support and recover its own systems in the case of a disruption.

	2.9		Weyerhaeuser shall lease office space to Newco and Newco Canada Exchangeco in Federal Way, Washington near Weyerhaeuser’s headquarters in the vicinity of Weyerhaeuser where its employees responsible for providing the Services and completing the Transition-out are located, such space being sufficient to provide office space for Newco’s and Newco Canada Exchangeco’s employees who, as reasonably determined by Newco and Newco Canada Exchangeco, need to be located at such location during the Transition Period in order to ensure the successful provision of the Services and the completion of the Transition-out. Such lease shall be on reasonable market terms commensurate with the space provided.

E-6

2.10

At or prior to the end of the Transaction Period, at the request of East, Weyerhaeuser shall purchase all hardware and equipment that is leased from EDS and dedicated to providing the Services and shall transfer ownership to Newco of all such hardware and equipment and all other hardware and equipment that is used to provide the Services and previously purchased from EDS, in exchange for the payment to Weyerhaeuser by Newco of the book value of all such hardware and equipment; provided, however, that Weyerhaeuser shall not be required to purchase and transfer to Newco any hardware and equipment that is used in Weyerhaeuser’s business.

PRICING, BILLING AND PAYMENT

	3.1		The Services will be charged to and payable by the Service Recipient in accordance with Schedules A, B and C hereto, as applicable, or as otherwise specified in this Agreement.

	3.2		Charges for Services shall be billed monthly by Weyerhaeuser and Weyerhaeuser Canada by no later than fifteen days after the end of the Weyerhaeuser Fiscal Month in which such Services are rendered and shall be payable by the Service Recipient to the Service Provider on the thirtieth day following the date of receipt of the invoice. In connection with the Services, the Parties further agree as follows:

(a)

The charge payable by the Service Recipient for any Service rendered during a Weyerhaeuser Fiscal Month that is quoted on an annual or monthly fee basis (as described on the applicable Schedule) shall be calculated by multiplying:

	(i)		the number of weeks during that Weyerhaeuser Fiscal Month in which the Service Provider has provided that Service; by

	(ii)		1/52 of any fee quoted on an annual basis or 1/4 of any fee quoted on a monthly basis based on the applicable fee for such Service as at the beginning of that Weyerhaeuser Fiscal Month (net of any agreed prior reductions to such fee).

	(b)		The charge payable by the Service Recipient for any Service rendered during a Weyerhaeuser Fiscal Month that is quoted on a one-time or hourly fee basis (as described on the applicable Schedule) shall be billed in the bill for the month or months in which the cost for such Service is incurred or such service is provided by the Service Provider.

	(c)		For the purposes of calculating the monthly charge described in sub-paragraph 3.2(a) above, use during any portion of a week during a Weyerhaeuser Fiscal Month shall be deemed to constitute use during the entirety of that week.

4.		ACCESS

		The Service Provider and the Service Recipient shall, and shall cause their respective affiliates to, provide to each other and their respective agents and vendors reasonable

E-7

		access (during normal business hours, upon reasonable notice and supervised by the appropriate personnel of the Parties) to the information, personnel, and systems necessary for the efficient and accurate administration of each of the Services and to avoid the duplication of any expenses or benefits thereunder; provided, that all such information shall be shared subject to the confidentiality obligations set forth in Section 6.30 of the Transaction Agreement, and any Party or third party vendor receiving such information shall agree to be bound by such obligations prior to the provision of any such information.

5.		TRANSITION

	5.1		The Parties agree to use their reasonable best efforts to cooperate with and assist each other in order to permit the Transition-out to occur as soon as reasonably practicable, but in any event prior to the end of the obligation of the Service Provider to provide such Services hereunder, taking into account the need to minimize both the cost of the Transition-out and the disruption to the ongoing business activities of the Parties. Weyerhaeuser and Weyerhaeuser Canada agree to provide to the Service Recipient such support as reasonably necessary for the Transition-out at the hourly rates specified in Schedules A, B and C hereto, or if not specified in such Schedules, then at actual cost. The Parties acknowledge that such support may include the provision of services requested by the Service Recipient in connection with its transition to non-Service Provider systems, including but not limited to migration of historical data, migration-specific enhancements and cooperation with and assistance to third party consultants engaged by the Service Recipient in connection with the foregoing.

	5.2		It is the intent of the parties that the Service Recipient will be able to perform for itself the Services following the discontinuance of such Services by the Service Provider. In furtherance of the foregoing, the Service Provider agrees to cooperate with and assist the Service Recipient with training of its personnel, including making its personnel and facilities available to train an agreed number of the Service Recipient’s personnel in connection with the Transition-Out to permit the Service Recipient to provide the Services for itself after the Transition Period.

WARRANTY AND INDEMNITY

	6.1		Subject to the provisions of Section 6.2 and 6.3, Weyerhaeuser (the “Indemnifying Party”) agrees to indemnify and hold Newco, Newco Canada Exchangeco and their respective affiliates (each an “Indemnified Party”) harmless from any damages, loss, cost or liability (including reasonable legal fees and expenses and the cost of enforcing this indemnity) arising out of or resulting from the negligence or wilful misconduct of the Indemnifying Party or any of its affiliates in the performance of the Services, or any breach of any representation, warranty, covenant or obligation under this Agreement by the Indemnifying Party or any of its affiliates.

	6.2		The amount of any damages, losses, costs or liabilities for which indemnification is provided under this Article 6 shall be net of any amounts actually recovered by the

E-8

			Indemnified Party in respect of such damages, losses, costs or liabilities under its insurance policies.

	6.3		Notwithstanding anything to the contrary contained herein, the liability of each Service Provider with respect to any Service provided pursuant to this Agreement or anything done in connection therewith, whether in contract, tort or otherwise, shall not exceed the fees previously paid by the Service Recipient to such Service Provider pursuant to this Agreement in respect of such category of Service.

7.		LIMITED WARRANTY. NOTWITHSTANDING ANY PROVISION TO THE CONTRARY, UNLESS EXPRESSLY SET FORTH HEREIN, EACH SERVICE PROVIDER REPRESENTS AND WARRANTS ONLY THAT IT SHALL USE ITS REASONABLE BEST EFFORTS TO PROVIDE THE SERVICES. THE ABOVE STATED LIMITED WARRANTY IS THE SERVICE PROVIDER’S SOLE AND EXCLUSIVE WARRANTY WITH RESPECT TO THE SERVICES. NO SERVICE PROVIDER MAKES ANY OTHER WARRANTIES, WHETHER EXPRESS OR IMPLIED, AND SPECIFICALLY DISCLAIMS ANY IMPLIED WARRANTIES, WHETHER OF MERCHANTABILITY, SUITABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR OTHERWISE FOR SAID SITE SERVICES.

8.		INCIDENTAL & CONSEQUENTIAL DAMAGES. NOTWITHSTANDING ANY PROVISION OR REPRESENTATION TO THE CONTRARY, EACH SERVICE PROVIDER SHALL ONLY BE LIABLE FOR DIRECT DAMAGES, WHICH FOR THE AVOIDANCE OF DOUBT SHALL EXCLUDE ANY INCIDENTAL, CONSEQUENTIAL, PUNITIVE, OR INDIRECT DAMAGES, INCLUDING, WITHOUT LIMITATION, ANY LOSS OF PROFITS, LOSS OF USE, DOWNTIME, OR LOSS OF SALES FOR ANY BREACH OF THIS AGREEMENT.

9.		FORCE MAJEURE

	9.1		The Service Provider shall not be responsible for failure or delay in delivery of any Service that it has responsibility for providing hereunder, nor shall the Service Recipient be responsible for failure or delay in receiving such Service, if caused by an act of God or public enemy, war, government acts, regulations or orders, fire, flood, embargo, quarantine, epidemic, labor stoppages or other disruptions, accident, unusually severe weather, or other similar cause beyond the control of the defaulting Party, provided that such Party shall have, promptly after knowledge of the beginning of any excusable delay, notified the other Parties of such delay, the reason therefor, and the probable duration and consequence thereof. The Party so excused shall use its reasonable best efforts to resume performance of its obligations hereunder with the least possible delay.

	9.2		In the event that any Service Provider is excused from supplying a Service pursuant to Section 9.1, the Service Recipient shall be free to acquire Replacement Services at the Service Recipient’s expense, and without liability to Weyerhaeuser or Weyerhaeuser

E-9

Canada, for the period and to the extent reasonably necessitated by such non-performance, or until notice is provided by the Service Recipient that it no longer desires to purchase such Service from the Service Provider, whereupon such Service shall be terminated.

		This Agreement and the information provided to each Party hereunder shall be subject to the confidentiality provisions set forth in Section 6.30 of the Transaction Agreement.

11.		TERMINATION

	11.1		This is a master agreement and shall be construed as a separate and independent agreement for each and every Service provided under this Agreement.

	11.2		Upon sixty days’ written notice, the Service Provider may terminate this Agreement with respect to any Service that it provides hereunder or, at its option, suspend performance of its obligations with respect thereto, in either case in the event of the failure of the Service Recipient to pay any invoice within thirty days of the receipt of such invoice or upon any other material breach by the Service Recipient of this Agreement with respect to such Service, unless the Service Recipient is disputing the invoice in good faith or the Service Recipient shall have paid the invoice or cured such breach within the sixty-day notice period.

	11.3		Any one or more of the Services may be terminated (a) upon mutual agreement of Parties or (b) at the Service Recipient’s option (i) upon thirty (30) days’ advance notice to the Service Provider, provided that the terminated Services are not required to be performed by the Service Provider in order to perform other Services under this Agreement, and (ii) pursuant to Section 9.2. All accrued and unpaid charges for Services shall be due and payable upon termination of this Agreement with respect to such Services.

	11.4		Following and prior to the termination of any Service, each Party shall cooperate in good faith with the other to transfer to Newco and Newco Canada Exchangeco all records and take all other actions necessary to provide Newco and Newco Canada Exchangeco and their respective successors and assigns with sufficient information in the form reasonably requested by Newco or Newco Canada Exchangeco, or their respective successors and assigns, as the case may be, to make alternative service arrangements (including internal arrangements) substantially consistent with those contemplated by this Agreement.

F-8

			which such event is declared or announced by Spinco (with contemporaneous notification thereof by Spinco to Newco Canada Exchangeco).

	(d)		The Board of Directors shall determine, in good faith and in its sole discretion, economic equivalence for the purposes of any event referred to in section 2.7(a) or 2.7(b) above and each such determination shall be conclusive and binding on Spinco and its shareholders. In making each such determination, the following factors shall, without excluding other factors determined by the Board of Directors to be relevant, be considered by the Board of Directors:

	(ii)		in the case of the issuance or distribution of any rights, options or warrants to subscribe for or purchase shares of Spinco Common Stock (or securities exchangeable for or convertible into or carrying rights to acquire shares of Spinco Common Stock), the relationship between the exercise price of each such right, option or warrant and the Current Market Price;

	(iii)		in the case of the issuance or distribution of any other form of property (including without limitation any shares or securities of Spinco of any class other than shares of Spinco Common Stock, any rights, options or warrants other than those referred to in section 2.7(d) (ii) above, any evidences of indebtedness of Spinco or any assets of Spinco), the relationship between the fair market value (as determined by the Board of Directors in the manner above contemplated) of such property to be issued or distributed with respect to each outstanding share of Spinco Common Stock and the Current Market Price; and

	(iv)		in the case of any subdivision, redivision or change of the then outstanding shares of Spinco Common Stock into a greater number of shares of Spinco Common Stock or the reduction, combination, consolidation or change of the then outstanding shares of Spinco Common Stock into a lesser number of shares of Spinco Common Stock or any amalgamation, merger, reorganization or other transaction affecting shares of Spinco Common Stock, the effect thereof upon the then outstanding shares of Spinco Common Stock.

Without limiting the generality of the foregoing, the Board of Directors of Newco Canada Exchangeco may adjust the number of shares of Spinco Common Stock into which an Exchangeable Share is

If only a part of the Exchangeable Shares are to be purchased by Newco Canada under the Exchange Right, the balance of such Exchangeable Shares shall be issued to the holder at the expense of Newco Canada Exchangeco either by a new certificate or through the direct registration system.

5.6 Delivery of Spinco Common Stock; Effect of Exercise

Promptly after the receipt of the notice of exercise of the Exchange Right, together with such documents and instruments of transfer required by section 5.5 (and payment of taxes, if any payable as contemplated by section 5.8 or evidence thereof), the Trustee shall notify Spinco, Newco Canada and Newco Canada Exchangeco of its receipt of the same, which notice to Spinco, Newco Canada and Newco Canada Exchangeco shall constitute exercise of the Exchange Right by the Trustee on behalf of the holder of such Exchangeable Shares, and Newco Canada shall promptly thereafter deliver or cause to be delivered to the Trustee (which delivery may be in the form of a certificate or in book-entry form through the direct registration system), for delivery to the Beneficiary of such Exchangeable Shares (or to such other persons, if any, properly designated by such Beneficiary) the number of shares of Spinco Common Stock issuable in connection with the exercise of the Exchange Right, and on the applicable payment date cheques for the balance, if any, of the total purchase price therefor without interest (but less any amounts withheld pursuant to section 5.13); provided, however, that no such delivery shall be made unless and until the Beneficiary requesting the same shall have paid (or provided evidence satisfactory to the Trustee, Newco Canada Exchangeco, Newco Canada and Spinco of the payment of) the taxes (if any) payable as contemplated by section 5.8 of this Agreement. Immediately upon the giving of notice by the Trustee to Spinco, Newco Canada and Newco Canada Exchangeco of the exercise of the Exchange Right as provided in this section 5.6, the closing of the transaction of purchase and sale contemplated by the Exchange Right shall be deemed to have occurred and the holder of such Exchangeable Shares shall be deemed to have transferred to Newco Canada, all of such holder’s right, title and interest in and to such Exchangeable Shares and the related interest in the Trust Estate and shall cease to be a holder of such Exchangeable Shares and shall not be entitled to exercise any of the rights of a holder in respect thereof, other than the right to receive his proportionate part of the total purchase price therefor, unless the requisite number of shares of Spinco Common Stock is not allotted, issued and delivered by Newco Canada, to the Trustee within five Business Days of the date of the

G-16

giving of such notice by the Trustee or the balance of the purchase price, if any, is not paid by Newco Canada, on the applicable payment date therefor, in which case the rights of the Beneficiary shall remain unaffected until such shares of Spinco Common Stock are so allotted, issued and delivered, and the balance of the purchase price, if any, has been paid, by Newco Canada. Upon delivery by Newco Canada, to the Trustee of such shares of Spinco Common Stock, and the balance of the purchase price, if any, the Trustee shall deliver such shares of Spinco Common Stock to such Beneficiary (or to such other persons, if any, properly designated by such Beneficiary), either in the form of a certificate or in book-entry form through the direct registration system. Concurrently with such Beneficiary ceasing to be a holder of Exchangeable Shares, the Beneficiary shall be considered and deemed for all purposes to be the holder of the shares of Spinco Common Stock delivered to it pursuant to the Exchange Right.

In any such event, Newco Canada Exchangeco hereby agrees with the Trustee and in favour of the Beneficiary promptly to forward or cause to be forwarded to the Trustee all relevant materials delivered by the Beneficiary to Newco Canada Exchangeco or to the transfer agent of the Exchangeable Shares (including without limitation, a copy of the retraction request delivered pursuant to section 3.6.1 of the Exchangeable Share Provisions) in connection with such proposed redemption of the Retracted Shares and the Trustee will thereupon exercise the Exchange Right with respect to the Retracted Shares that Newco Canada Exchangeco is not permitted to redeem and will require Newco Canada to purchase such shares in accordance with the provisions of this Article 5.

Spinco will in good faith expeditiously take all such actions and do all such things as are reasonably necessary or desirable to cause all shares of Spinco Common Stock (or such other shares or securities) to be delivered pursuant to the Exchange Right or the Automatic Exchange Rights to be listed, quoted or posted for trading on all stock exchanges and quotation systems on which outstanding shares of Spinco Common Stock (or such other shares or securities) have been listed by Spinco and remain listed and are quoted or posted for trading at such time.

Spinco hereby represents, warrants and covenants that the shares of Spinco Common Stock issuable as described herein will be duly authorized and validly issued as fully paid and non-assessable and shall be free and clear of any lien, claim or encumbrance.

(a)

Spinco will give the Trustee written notice of each of the following events at the time set forth below:

G-18

	(i)		in the event of any determination by the board of directors of Spinco to institute voluntary liquidation, dissolution or winding-up proceedings with respect to Spinco or to effect any other distribution of assets of Spinco among its shareholders for the purpose of winding up its affairs, at least 60 days prior to the proposed effective date of such liquidation, dissolution, winding-up or other distribution; and

	(ii)		as soon as practicable following the earlier of (A) receipt by Spinco of notice of, and (B) Spinco otherwise becoming aware of, any threatened or instituted claim, suit, petition or other proceedings with respect to the involuntary liquidation, dissolution or winding-up of Spinco or to effect any other distribution of assets of Spinco among its shareholders for the purpose of winding up its affairs, in each case where Spinco has failed to contest in good faith any such proceeding commenced in respect of Spinco within 30 days of becoming aware thereof.

	(b)		As soon as practicable following receipt by the Trustee from Spinco of notice of any event (a “Liquidation Event”) contemplated by section 5.12(a)(i) or 5.12(a)(ii) above, the Trustee will give notice thereof to the Beneficiaries. Such notice shall be provided to the Trustee by Spinco and shall include a brief description of the automatic exchange of Exchangeable Shares for shares of Spinco Common Stock provided for in section 5.12(c).

	(c)		In order that the Beneficiaries will be able to participate on a pro rata basis with the holders of shares of Spinco Common Stock in the distribution of assets of Spinco in connection with a Liquidation Event, on the fifth Business Day prior to the effective date (the “Liquidation Event Effective Date”) of a Liquidation Event all of the then outstanding Exchangeable Shares shall be automatically exchanged for shares of Spinco Common Stock. To effect such automatic exchange, Newco Canada, shall purchase on the fifth Business Day prior to the Liquidation Event Effective Date each Exchangeable Share then outstanding and held by Beneficiaries, and each Beneficiary shall sell the Exchangeable Shares held by it at such time, for a purchase price per share equal to (a) the Current Market Price of a share of Spinco Common Stock on the fifth Business Day prior to the Liquidation Event Effective Date, which shall be satisfied in full by Newco Canada, issuing to the Beneficiary one share of Spinco Common Stock, and (b) to the extent not paid by Newco Canada Exchangeco, an additional amount equal to and in satisfaction of the full amount of all declared and unpaid dividends on each such Exchangeable Share held by such holder on any dividend record date which occurred prior to the date of the exchange. Newco Canada, shall provide the Trustee with an Officer’s Certificate in connection with each automatic exchange setting forth the calculation of the purchase price for each Exchangeable Share.

	(d)		On the fifth Business Day prior to the Liquidation Event Effective Date, the closing of the transaction of purchase and sale contemplated by the automatic exchange of Exchangeable Shares for shares of Spinco Common Stock shall be deemed to have occurred, and each Beneficiary shall be deemed to have transferred to Newco Canada, all of the Beneficiary’s right, title and interest in and to such Beneficiary’s Exchangeable Shares and the related interest in the

G-19

Trust Estate, any right of each such Beneficiary to receive declared and unpaid dividends from Newco Canada Exchangeco shall be deemed to be satisfied and discharged and each such Beneficiary shall cease to be a holder of such Exchangeable Shares and Newco Canada, shall deliver to the Beneficiary the shares of Spinco Common Stock issuable upon the automatic exchange of Exchangeable Shares for shares of Spinco Common Stock and on the applicable payment date shall deliver to the Trustee for delivery to the Beneficiary a cheque for the balance, if any, of the total purchase price for such Exchangeable Shares without interest but less any amounts withheld pursuant to section 5.13. Concurrently with such Beneficiary ceasing to be a holder of Exchangeable Shares, the Beneficiary shall be considered and deemed for all purposes to be the holder of the shares of Spinco Common Stock issued pursuant to the automatic exchange of Exchangeable Shares for shares of Spinco Common Stock and the certificates, if any, held by the Beneficiary previously representing the Exchangeable Shares exchanged by the Beneficiary with Spinco pursuant to such automatic exchange shall thereafter be deemed to represent shares of Spinco Common Stock delivered to the Beneficiary by Newco Canada, pursuant to such automatic exchange. Upon the request of a Beneficiary and the surrender by the Beneficiary of Exchangeable Share certificates, if any, deemed to represent shares of Spinco Common Stock, duly endorsed in blank and accompanied by such instruments of transfer as Newco Canada, may reasonably require, Newco Canada, shall deliver or cause to be delivered to the Beneficiary the shares of Spinco Common Stock of which the Beneficiary is the holder (which delivery may be in the form of a certificate or, in whole or in part, in book entry form through the direct registration system).

5.13 Withholding Rights

Spinco, Newco Canada, Newco Canada Exchangeco and the Trustee shall be entitled to deduct and withhold from any dividend or any consideration otherwise payable under this Agreement to any holder of Exchangeable Shares or shares of Spinco Common Stock such amounts as Spinco, Newco Canada, Newco Canada Exchangeco or the Trustee is required or permitted to deduct and withhold with respect to such payment under (i) the Income Tax Act (Canada) (the “ITA”), the United States Internal Revenue Code of 1986 or any provision of provincial, state, local or foreign tax law, in each case as amended or succeeded or (ii) required or permitted in order to comply with section 116 of the ITA or any corresponding provisions of provincial laws. The Trustee may act on the advice of counsel with respect to such matters. To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes as having been paid to the holder of the shares in respect of which such deduction and withholding was made, provided that such withheld amounts are actually remitted to the appropriate taxing authority. To the extent that the amount so required to be deducted or withheld from any payment to a holder exceeds the cash portion of the consideration otherwise payable to the holder, Spinco, Newco Canada, Newco Canada Exchangeco and the Trustee are hereby authorized to sell or otherwise dispose of such portion of the consideration as is necessary to provide sufficient funds to Spinco, Newco Canada, Newco Canada Exchangeco or the Trustee, as the case may be, to enable it to comply with such deduction or withholding requirement and Spinco, Newco Canada, Newco Canada Exchangeco or the Trustee shall notify the holder thereof and remit to such holder any unapplied balance of the net proceeds of such sale. Each of Spinco and Newco Canada represents and warrants that, based upon facts currently known to it,

G-20

it has no current intention, as at the date of this Agreement, to deduct or withhold from any dividend paid to holders of Exchangeable Shares any amounts under the United States Internal Revenue Code of 1986.

In the exercise of such rights, powers, duties and authorities the Trustee shall have (and is granted) such incidental and additional rights, powers, duties and authority not in conflict with any of the provisions of this Agreement as the Trustee, acting in good faith and in the reasonable exercise of its discretion, may deem necessary, appropriate or desirable to effect the purpose of the Trust.

(b) Domtar represents and warrants that, as of the Distribution Date, none of Domtar, its Subsidiaries or any Controlling Shareholder of Domtar (including

H-12

any officers or directors acting on behalf of Domtar or any of its Subsidiaries, or any Person acting with the implicit or explicit permission of any such officers, directors or Controlling Shareholder) will have, or will have had since the date of this Agreement, any agreements, understandings, arrangements or negotiations as determined for purposes of Code Section 355(e) and the Treasury Regulations thereunder concerning the acquisition of Spinco Capital Stock other than the agreements, understandings and arrangements expressly contemplated by the Transaction Documents.

SECTION 4.02 Covenants. (a) During the Restricted Period, Weyerhaeuser shall not take or fail to take, or permit its Subsidiaries to take or fail to take, any action where that action (or the failure to take such action) would (i) violate, be inconsistent with or cause to be untrue any covenant, representation or statement made by Weyerhaeuser or its Subsidiaries in any letter or certificate that forms the basis of any Tax Opinion (including the Spinco Letter or the Weyerhaeuser Letter) or any ruling from the IRS concerning the Contribution and Distribution (including the Representations) or (ii) prevent, or be reasonably likely to prevent, the Tax-Free Status of the Contribution and the Distribution. During the Restricted Period, Spinco shall not take or fail to take, or permit its Subsidiaries to take or fail to take, any action where that action (or the failure to take such action) would (x) violate, be inconsistent with or cause to be untrue any covenant, representation or statement made by Spinco after the Distribution Date or by Domtar in any letter or certificate that forms the basis of any Tax Opinion (including the Domtar Letter) or any ruling from the IRS concerning the Contribution and Distribution (including the Representations) or (y) prevent, or be reasonably likely to prevent, the Tax-Free Status of the Contribution and the Distribution.

(b) During the Restricted Period, the Spinco Group shall not, and shall not permit its Affiliates to, in a single transaction or in a series of transactions:

(i) enter into any agreement, understanding, arrangement or substantial negotiations as determined for purposes of Code Section 355(e) and the Treasury Regulations thereunder, in connection with which any Person (or, in the case of an Affiliate that is a Controlling Shareholder, such Controlling Shareholder) would (directly or indirectly) acquire, or have the right to acquire, from any other Person, any interest in Spinco Capital Stock (except to the extent contemplated under the Transaction Documents) (a “Proposed Acquisition Transaction”). For these purposes, (a) any recapitalization, repurchase or redemption of Spinco Capital Stock and any amendment to the certificate of incorporation (or other organizational documents) of Spinco shall be treated as an indirect acquisition of such stock by a shareholder to the extent such shareholder’s percentage interest in the outstanding equity for U.S. federal income tax purposes in the issuer increases by vote or value and (b) if Spinco merges into another entity or consolidates with another entity to form a new entity (such other or new entity “Merged Entity”), Spinco Capital Stock shall refer to the capital stock of the Merged Entity and references in this Agreement to Spinco shall mean the Merged Entity. Notwithstanding the foregoing, a Proposed Acquisition Transaction shall not include (w) the adoption by Spinco of, or an issuance under, a shareholder rights plan that is described in or is similar to the shareholder rights plan described in

H-13

IRS Revenue Ruling 90-11 (for this purpose a shareholder rights plan will be considered similar to the plan described in IRS Revenue Ruling 90-11 only if the principal purpose for the adoption of the plan providing for such rights is to establish a mechanism by which a publicly held corporation can, in the future, provide shareholders with rights to purchase stock at substantially less than fair market value as a means of responding to unsolicited offers to acquire the corporation); (x) redemptions or repurchases of Spinco Capital Stock pursuant to open market repurchase programs meeting the requirements of Section 4.05(1)(b) of IRS Revenue Procedure 96-30; (y) issuances of Spinco Capital Stock pursuant to an employee stock purchase agreement or equity compensation plan described in and meeting the requirements of Safe Harbor VIII (relating to acquisitions by persons in connection with the performance of services) of Treasury Regulation Section 1.355-7(d), provided, however, that prior to adopting, modifying or amending any employee stock purchase agreement or equity compensation plan (but not for each issuance of Spinco Capital Stock pursuant thereto) Spinco must first obtain (at its expense) an Unqualified Tax Opinion that any issuance of capital stock of Spinco treated as equity in Spinco for U.S. federal income tax purposes under such new, modified or amended agreement or plan would meet the requirements of Safe Harbor VIII; and (z) issuances of Spinco Capital Stock described in and meeting the requirements of Safe Harbor IX (relating to the acquisition by a retirement plan of an employer) of Treasury Regulation Section 1.355-7(d);

(ii) liquidate Spinco or reclassify Spinco as other than a corporation for U.S. federal income tax purposes; or

(iii) cause or permit Spinco to cease to engage in the Active Trade or Business; provided, however, that the Spinco Group shall be permitted to sell or otherwise dispose of Newco Assets and Newco Canada Exchangeco Assets the EBITDA of which represents (taking into account all other sales and dispositions, other than assets sold or transferred in the ordinary course of business, by the Spinco Group of the Newco Assets and Newco Canada Exchangeco Assets after the Distribution Date) no more than 33 ¹^/3 percent of the EBITDA of the Newco Assets and Newco Canada Exchangeco Assets, provided further, that nothing herein shall prevent the Spinco Group from selling or disposing of assets in the ordinary course of business. For these purposes, EBITDA of the Newco Assets and Newco Canada Exchangeco Assets shall mean the EBITDA generated by such assets during the year ending as of the quarter immediately following the Distribution Date.

(c) Notwithstanding anything to the contrary in any Transaction Document, representation letter or other document or agreement:

(i) Clauses (i) through (iii) of paragraph (b) shall not apply to Spinco upon the prior written consent of Weyerhaeuser, which consent may not be withheld if Weyerhaeuser determines in good faith that Spinco has provided it

H-14

with Satisfactory Guidance concluding that the proposed actions will not result in incremental U.S. federal Transaction Taxes.

(ii) In reliance on the representation and warranty provided by Weyerhaeuser in Section 4.01(a)(iii), Spinco shall be permitted to issue Spinco Capital Stock beginning on the day after the one year anniversary of the Distribution Date, provided that (a) Spinco must first obtain (at its expense) an Unqualified Tax Opinion that is reasonably acceptable to Weyerhaeuser (such acceptance to be notified by Weyerhaeuser to Spinco in writing within five business days from receipt by Weyerhaeuser of such Unqualified Tax Opinion, it being understood that Weyerhaeuser shall be considered to have waived its rights to receive an Unqualified Tax Opinion under this Section 4.02(c)(ii) if it fails to indicate either its acceptance of, or objection to, the Unqualified Tax Opinion within such five business days or fails to reaffirm in writing to the Tax Advisor preparing such Unqualified Tax Opinion the representation and warranty provided by Weyerhaeuser in Section 4.01(a)(iii) within five business days of request therefor) that such issuance would meet the requirements of Safe Harbor III of Treasury Regulation Section 1.355-7(d); (b) such Unqualified Tax Opinion is based on the representation and warranty provided by Domtar in Section 4.01(b); and (c) such Unqualified Tax Opinion is based on a representation and warranty by Spinco that none of Spinco, its Subsidiaries or any Controlling Shareholder of Spinco (including any officers or directors acting on behalf of Spinco or any of its Subsidiaries, or any Person acting with the implicit or explicit permission of any such officers, directors or Controlling Shareholder) has had any agreements, understandings, arrangements or substantial negotiations as determined for purposes of Code Section 355(e) and the Treasury Regulations thereunder concerning such issuance or any similar issuance of Spinco Capital Stock during the one year period beginning on the Distribution Date. The sole basis for an Unqualified Tax Opinion provided under this Section 4.02(c)(ii) not to be reasonably acceptable to Weyerhaeuser shall be on grounds that the letter or certificate provided by Spinco in connection with such Unqualified Tax Opinion was manifestly incorrect as to fact or that the Unqualified Tax Opinion was manifestly incorrect as to law. Nothing in this Section 4.02(c)(ii) shall be construed to relieve the Spinco Group of any liability under Section 2.02 of this Agreement resulting from such acquisition or issuance of Spinco Capital Stock except to the extent that such liability is attributable to a breach of the representation and warranty provided by Weyerhaeuser in Section 4.01(a)(iii).

(iii) The Spinco Group shall be permitted to issue or transfer Spinco Capital Stock to any Person to the extent such issuance or transfer is required or expressly permitted under any option, right, privilege or similar instrument existing as of immediately after the Closing Date.

(iv) The Spinco Group shall be permitted to take any action (or not take an action) required or expressly permitted under any Transaction Document (other than this Agreement) or described in the IRS Ruling.

H-15

SECTION 4.03 Procedures Regarding Opinions and Rulings. (a) If the Spinco Group may take certain actions conditioned upon the receipt of Satisfactory Guidance, Weyerhaeuser, at the request of Spinco, shall use commercially reasonable efforts to expeditiously obtain, or assist Spinco in obtaining, such Satisfactory Guidance, including affirming to the relevant Tax Advisor or the IRS the representations made by Weyerhaeuser in this Agreement and making other representations that are reasonably requested by Spinco. Weyerhaeuser shall not be required to take any action pursuant to this Section 4.03(a) if Spinco fails to certify, upon request, that all representations and warranties made by Spinco after the Distribution Date in any letter or certificate forming the basis of any prior Tax Opinion or ruling from the IRS, relating to the Tax-Free Status of the Contribution and the Distribution, are true, correct and complete. Spinco shall reimburse Weyerhaeuser for all reasonable out-of-pocket costs and expenses incurred by Weyerhaeuser in obtaining Satisfactory Guidance.

(b) Weyerhaeuser shall have the right to obtain an Unqualified Tax Opinion at any time in its sole discretion. Weyerhaeuser shall reimburse the Spinco Group for all reasonable out-of-pocket costs and expenses incurred by the Spinco Group in obtaining such an Unqualified Tax Opinion.

ARTICLE V

Tax Contests; Indemnification; Cooperation

SECTION 5.01 Notice. Within 10 days after a party (the “Indemnitee”) becomes aware of the existence of a Tax Contest that may give rise to an indemnification claim under this Agreement by it against the other party (the “Indemnifying Party”), the Indemnitee shall notify the Indemnifying Party of the Tax Contest, and thereafter shall promptly forward or make available to the Indemnifying Party copies of notices and communications with a Taxing Authority relating to such Tax Contest.

SECTION 5.02 Control of Tax Contests. (a) Except as otherwise provided in paragraph (b), Weyerhaeuser may elect to control, and to have sole discretion in handling, settling or contesting, any Tax Contest relating to (i) any Tax Returns with respect to the Spinco Group (other than Domtar and its Subsidiaries) for any taxable period ending on or before the Distribution Date or (ii) the Tax liability arising from the failure of the Contribution and Distribution to qualify for Tax-Free Status. Notwithstanding the foregoing, Weyerhaeuser shall keep Spinco informed of material developments concerning any Tax Contest affecting the Spinco Group, the Newco Business, the Newco Assets or the Newco Canada Exchangeco Assets and shall not settle or compromise any Tax Contest in a manner that could materially adversely affect the Spinco Group after the Distribution Date without the prior written consent of Spinco.

(b) Spinco shall control and shall have sole discretion in handling, settling or contesting any Tax Contest relating to Transfer Tax Returns. Weyerhaeuser and Spinco shall jointly control Tax Contests relating to (i) Separate Returns of any member of the Spinco Group (other than Domtar and its Subsidiaries) for the Straddle Period and (ii) Tax liability arising from the failure of the Contribution and Distribution

H-16

to qualify for Tax-Free Status, if the Spinco Group potentially would be liable to Weyerhaeuser under Article II for Taxes arising in connection with such Tax Contest. Neither party shall have the right to settle any such Tax Contest without the consent of the other party.

(c) Any reasonable out-of-pocket costs incurred in handling, settling or contesting a Tax Contest shall be borne ratably by the parties based on their ultimate liability under this Agreement for the Taxes to which the Tax Contest relates.

SECTION 5.03 Indemnification Payments. If an Indemnitee has a claim for an indemnification payment from an Indemnifying Party under this Agreement, the Indemnitee shall promptly provide to the Indemnifying Party notice of such claim, including a description of such claim and a detailed calculation of the amount of the indemnification payment that is claimed. The Indemnifying Party shall make the claimed payment to the Indemnitee within 30 days after receiving such notice, unless the Indemnifying Party reasonably disputes the amount of, or its liability for, such payment.

SECTION 5.04 Payment of Refunds, Credits and Offsets. Each party shall forward, and shall cause its Subsidiaries to forward, to the party entitled to receive the amount or economic benefit of a refund, credit or offset to Tax the amount of such refund, credit or offset within 10 days after such refund is received or after such credit or offset is allowed or applied against another Tax liability, as the case may be.

SECTION 5.05 Treatment of Payments. The amount of all indemnification obligations under this Agreement shall be (a) increased to take account of any net Tax cost actually incurred by the Indemnitee arising from the receipt of indemnity payments hereunder (grossed up for such increase) and (b) reduced to take account of any net Tax benefit actually realized by the Indemnitee arising from the incurrence or payment of any such indemnified amount. In computing the amount of any such Tax cost or Tax benefit, the Indemnitee shall be deemed to recognize all other items of income, gain, loss, deduction or credit before recognizing any item arising from the receipt of any indemnity payment hereunder or the incurrence or payment of any indemnified amount.

SECTION 5.06 Expenses. Except as otherwise provided herein, each party and its Subsidiaries shall bear their own expenses incurred in connection with preparation of Tax Returns, Tax Contests, and other matters under this Agreement.

SECTION 5.07 Cooperation. Each member of the Weyerhaeuser Group and the Spinco Group shall cooperate fully with all reasonable requests from the other party in connection with the preparation and filing of Tax Returns, Adjustment Requests and Tax Contests concerning issues or other matters covered by this Agreement.

(a) Such cooperation shall include:

(i) the retention until the expiration of the applicable statute of limitations, and the provision upon request, of Tax Returns, books, records (including information regarding ownership and Tax basis of property), documentation and other information relating to the Tax Returns, including

H-17

accompanying schedules, related workpapers, and documents relating to rulings or other determinations by Taxing Authorities;

(ii) the execution of any document that may be necessary or reasonably helpful in connection with any Tax Contest, the filing of a Tax Return or Adjustment Request by a member of the Weyerhaeuser Group or Spinco Group, or other matters covered by this Agreement, including certification (provided in such form as may be required by applicable law or reasonably requested and made to the best of a party’s knowledge) of the accuracy and completeness of the information it has supplied;

(iii) the use of the parties’ reasonable best efforts to obtain any documentation that may be necessary or reasonably helpful in connection with any of the foregoing; and

(iv) the use of the parties’ reasonable best efforts to make the applicable party’s current or former directors, officers, employees, agents and facilities available on a reasonable and mutually convenient basis in connection with the foregoing matters.

(b) If a party fails to comply with any of its obligations set forth in this Section 5.07 upon reasonable request and written notice by the other party, and such failure results in the imposition of additional Taxes, the nonperforming party shall be liable in full for such additional Taxes.

SECTION 5.08 Confidentiality. Any information or documents provided under this Agreement shall be kept confidential by the recipient-party, except as may otherwise be necessary in connection with the filing of Tax Returns or with any Tax Contest. In addition, if Weyerhaeuser or Spinco determines that providing such information could be commercially detrimental, violate any law or agreement or waive any privilege, the parties shall use reasonable best efforts to permit compliance with the obligations under this Agreement in a manner that avoids any such harm or consequence.

SECTION 5.09 Retention of Tax Records. Spinco may request from Weyerhaeuser and retain copies of any Separate Returns for any Spinco Group members, including supporting schedules and workpapers. Neither Weyerhaeuser nor Spinco shall, or permit any of their Subsidiaries to, dispose of documentation with respect to any Pre-Distribution Period, including books, records, Tax Returns and all supporting schedules and information relating thereto of any member of the other Group prior to the expiration of the applicable statute of limitations. If either Weyerhaeuser or Spinco intends to dispose of documentation relating to Taxes (other than any such documentation relating to Domtar or its Subsidiaries) with respect to any Pre-Distribution Period, including books, records, Tax Returns and all supporting schedules and information relating thereto (after the expiration of the applicable statute of limitations), of any member of the other Group, they shall provide written notice to the other party describing the documentation to be disposed of 30 days prior to taking such action. The other party may arrange to take

H-18

delivery of the documentation described in the notice at its own expense during the succeeding 30 day period.

ARTICLE VI

Resolution of Disputes

SECTION 6.01 Tax Disputes. The parties will endeavor, and will cause their respective Subsidiaries to endeavor, to resolve in an amicable manner all disputes arising in connection with this Agreement. The parties shall negotiate in good faith to resolve any Tax Dispute for not less than 45 days. Upon written notice of either party after 45 days, the matter will be referred to a Tax Advisor acceptable to both parties. The Tax Advisor may, in its discretion, obtain the services of any third-party necessary to assist it in resolving the dispute. The Tax Advisor shall furnish written notice to the Companies of its resolution of the dispute as soon as practicable, but in any event no later than 45 days after its acceptance of the matter for resolution. Any such resolution by the Tax Advisor will be binding on the parties and the parties shall take, or cause to be taken, any action necessary to implement the resolution. All fees and expenses of the Tax Advisor shall be shared equally by Weyerhaeuser and Spinco. If, having determined that the dispute must be referred to a Tax Advisor, after 45 days the parties are unable to find a Tax Advisor willing to adjudicate the dispute in question and whom the parties in good faith find acceptable, then the dispute will be submitted for arbitration to the American Arbitration Association; provided, however, that only an arbitrator that qualifies as a Tax Advisor shall be selected. Notwithstanding the foregoing, this Article VI shall not apply to any dispute arising under Section 2.02 with respect to the respective liability of the parties in the event Transaction Taxes or Third Party Transaction Taxes are imposed.

ARTICLE VII

Spinco shall provide reasonable assistance to Weyerhaeuser in the preparation of the Statement and shall provide Weyerhaeuser reasonable access at all reasonable times to the personnel, properties, books and records of the Newco Business for such purpose.

(b) Objections; Resolution of Disputes. The Statement shall become final and binding upon the parties on the 30th day following delivery thereof, unless Spinco gives written notice of its disagreement with the Statement (a “Notice of Disagreement”) to Weyerhaeuser prior to such date. Any Notice of Disagreement shall (i) specify in reasonable detail the nature of any disagreement so asserted, and (ii) only include disagreements based on mathematical errors or based on Closing Working Capital not being calculated in accordance with this Section 2.04. If a Notice of Disagreement is received by Weyerhaeuser in a timely manner, then the Statement (as revised in accordance with this sentence) shall become final and binding upon Weyerhaeuser and Spinco on the earlier of (A) the date Weyerhaeuser and Spinco resolve in writing any differences they have with respect to the matters specified in the Notice of Disagreement, and (B) the date any disputed matters are finally resolved in writing by the Accounting Firm. During the 30-day period following the delivery of a Notice of Disagreement, Weyerhaeuser and Spinco shall seek in good faith to resolve in writing any differences that they may have with respect to the matters specified in the Notice of Disagreement. At the end of such 30-day period, Weyerhaeuser and Spinco shall submit to an independent accounting firm (the “Accounting Firm”) for arbitration any and all matters that remain in dispute and were properly included in the Notice of Disagreement. The Accounting Firm shall be Deloitte & Touche LLP or, if such firm is unable or unwilling to act, such other nationally recognized independent public accounting firm as shall be agreed upon by the parties hereto in writing. Weyerhaeuser and Spinco shall use reasonable efforts to cause the Accounting Firm to render a decision resolving the matters submitted to the Accounting Firm within 30 days of receipt of the submission. Judgment may be entered upon the determination of the Accounting Firm in any court having jurisdiction over the party against which such determination is to be enforced. The cost of any arbitration (including the fees and expenses of the Accounting Firm and reasonable attorney fees and expenses of the parties) pursuant to this Section 2.04 shall be equally shared by Spinco and Weyerhaeuser. Other than the fees and expenses referred to in the immediately preceding sentence, the fees and disbursements of

Weyerhaeuser’s independent auditors shall be borne by Weyerhaeuser and the fees and disbursements of Spinco’s independent auditors shall be borne by Spinco.

(c) Adjustment Payment. If the Closing Working Capital is less than $500,000,000, Weyerhaeuser shall, within ten business days after the Statement becomes final and binding on the parties, pay to Spinco the amount by which Closing Working Capital is less than $500,000,000. If the Closing Working Capital exceeds $600,000,000, Spinco shall, within 10 Business Days after the Statement becomes final and binding on the parties, pay to Weyerhaeuser the amount by which Closing Working Capital exceeds $600,000,000. Any payment made pursuant to this Section 2.04(c) shall be made by wire transfer in immediately available funds to one or more accounts designated in writing at least two business days prior to such payment by the party entitled to receive such payment together with interest thereon at a rate of interest per annum equal to the rate of interest from time to time announced publicly by JPMorgan Chase Bank as its prime rate, calculated on the basis of the actual number of days elapsed divided by 365, from the Closing Date to the date of payment.

(d) Working Capital. The term “Working Capital” means Current Assets minus Current Liabilities. The terms “Current Assets” and “Current Liabilities” mean the current assets and current liabilities, respectively, of the portion of the Newco Business, calculated in the same way, using the same methods, policies, principles and methodologies, as the line items on the Interim Newco Balance Sheet, subject to adjustment in accordance with the Working Capital Principles. Closing Working Capital shall include the Shared Payment Amount. Without limiting the generality of the foregoing, Closing Working Capital is to be calculated (i) using the methods, policies, principles and methodologies set forth on Schedule 2.04(d), whether or not doing so is in accordance with (A) the methods used for calculating Working Capital on the Interim Newco Balance Sheet or (B) GAAP, (ii) if Schedule 2.04(d) does not set forth relevant methods, policies, principles and methodologies, the Closing Working Capital is to be calculated in the same way, using the same methods, policies, principles and methodologies, as were used by Weyerhaeuser in preparation of the Interim Newco Balance Sheet, whether or not doing so is in accordance with GAAP, and (iii) if no relevant methods, policies, principles and methodologies are available pursuant to the foregoing clauses (i) and (ii), the Closing Working Capital is to be calculated in accordance with GAAP applied in a manner consistent with Weyerhaeuser’s historic methods, policies, principles and methodologies excluding any effects of the transactions contemplated by this Agreement. The foregoing principles are referred to in this Agreement as the “Working Capital Principles”. Closing Working Capital is to be calculated as of close of business on the day prior to the Closing Date in accordance with the Working Capital Principles. The scope of the disputes to be resolved by the Accounting Firm as provided in Section 2.04(b) shall be solely limited to whether such calculation was done in accordance with the Working Capital Principles, and whether there were mathematical errors in the Statement. Under no circumstances shall the Accounting Firm be authorized or permitted to make any other determination or adjustment based on GAAP if Working Capital Principles can be determined pursuant to clauses (i) and (ii) of the definition thereof. For purposes of this Section 2.04(d), any items on or omissions from the Interim Newco Balance Sheet that are based upon errors

of fact or mathematical errors or that are not in accordance with GAAP shall be retained for purposes of calculating Closing Working Capital. Without limiting the generality of the foregoing, the Accounting Firm is not authorized or permitted to make any determination as to the accuracy of any representation or warranty in this Agreement or as to compliance by Weyerhaeuser with any of its covenants in this Agreement (other than in this Section 2.04).

(e) Post-Closing Books and Records. Following the Closing Date, neither Spinco nor Weyerhaeuser shall take any actions with respect to the accounting books and records of the Business on which the Statement is to be based that would affect the Statement. During the period of time from and after the Closing Date through the resolution of any payment contemplated by Section 2.04(c) or 2.04(f), each of Spinco and Weyerhaeuser shall afford to each other and their respective accountants and counsel in connection with any actions contemplated by this Section 2.04 reasonable access during normal business hours to all the properties, books, contracts, personnel and records of such party relevant to the Statement, the Notice of Disagreement and any payments contemplated by this Section 2.04.

(f) Shared Payment Amount. On the day that Weyerhaeuser delivers to Spinco the Statement in accordance with Section 2.04(a), Weyerhaeuser shall pay to Spinco an amount equal to (1)(A) the sum of the amount of Shared Accounts Receivable and the amount of Shared Inventory, in each case as reflected on the Statement, minus (B) the amount of the Shared Accounts Payable as reflected on the Statement (the amount so calculated, the “Shared Payment Amount”), plus (2) an amount (the “Pulp Inventory Adjustment Amount”) equal to 100% of the sum of (A) the LIFO reserve applicable to the Shared Inventory reflected on the Statement (the “LIFO Reserve Amount”) and (B) an amount equal to 5% multiplied by the sum of the Shared Inventory, as reflected in the Statement, and the LIFO Reserve Amount. On the day that the Statement becomes final in accordance with Section 2.04(b), (i) if the Statement (as revised in accordance with Section 2.04(b)) reflects an increase in the Shared Payment Amount or the Pulp Inventory Adjustment Amount, Weyerhaeuser shall pay to Spinco the amount of such increase, and (ii) if the Statement (as revised in accordance with Section 2.04(b)) reflects a decrease in the Shared Payment Amount or the Pulp Inventory Adjustment Amount, Spinco shall pay to Weyerhaeuser the amount of such decrease. Any payment made pursuant to this Section 2.04(f) shall be made by wire transfer in immediately available funds to one or more accounts designated in writing at least two Business Days prior to such payment by the party entitled to receive such payment together. The payment pursuant to this Section 2.04(f) shall be independent of whether a payment is due pursuant to Section 2.04(c). Immediately following the Effective Time, (i) Newco shall transfer and assign to Weyerhaeuser the Shared Inventory and the Shared Accounts Receivable, and (ii) Weyerhaeuser shall assume from Newco the Shared Accounts Receivable. At such time, Newco and Spinco shall have no further rights with respect to the Shared Accounts Receivable and the Shared Inventory (which will become Excluded Assets) and shall have no further obligations with respect to the Shared Accounts Payable (which will become Retained Liabilities) other than the right to receive the payments provided for in this Section 2.04(f). Notwithstanding anything to the contrary in the Transaction Documents, Weyerhaeuser shall at any time control the collection of the Shared Accounts

Receivables and the sale of the Shared Inventory and Newco and Spinco shall have no rights to dispute at any time any actions or omissions by Weyerhaeuser in connection therewith.

(g) Allocations and Payments to the Weyerhaeuser Subsidiary.

SECTION 2.09. Governmental Approvals and Consents. (a) Subject to Section 6.07(c) of the Transaction Agreement, upon the terms and subject to the conditions set forth in this Agreement, each of the parties hereto shall use its reasonable best efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other parties in doing, all things necessary, proper or advisable to consummate and make effective, on the Contribution Date or the Distribution Date, as applicable, the transactions contemplated by this Agreement and the other Transaction Documents, including (i) the obtaining of all necessary actions or nonactions, waivers, consents and approvals from Governmental Entities and the making of all necessary registrations and filings (including filings with Governmental Entities, if any) and the taking of all reasonable steps as may be necessary to obtain an approval or waiver from, or to avoid an action or proceeding by, any Governmental Entity, (ii) the obtaining of all necessary consents, approvals or waivers from third parties, (iii) the defending of any lawsuits or other legal proceedings, whether judicial or administrative, challenging this Agreement or any other Transaction Document including seeking to have any stay or temporary restraining order entered by any court or other Governmental Entity vacated or reversed and (iv) the execution and delivery of any additional instruments necessary to consummate the transactions contemplated by this Agreement and the Ancillary Agreements.

(b) If the transfer, assignment or assumption of any Delayed Transfer Asset or any Delayed Transfer Liability intended to be transferred, assigned or assumed hereunder is not consummated prior to or at the Contribution Date then the member of the Weyerhaeuser Group retaining such Delayed Transfer Asset or such Delayed Transfer Liability shall thereafter hold such Delayed Transfer Asset or such Delayed Transfer Liability for the use and benefit, insofar as reasonably practicable, of Newco (at the expense of Newco). In addition, the member of the Weyerhaeuser Group retaining such Delayed Transfer Asset or such Delayed Transfer Liability shall take such other actions in order to place Newco, insofar as reasonably practicable, in the same position as if such Delayed Transfer Asset or such Delayed Transfer Liability had been transferred or assumed as contemplated hereby and so that all the benefits and burdens relating to such Delayed Transfer Asset or such Delayed Transfer Liability, including possession, use, risk of loss, potential for gain, and dominion, control and command over such asset, are to inure from and after the Contribution Date to Newco. To the extent permitted by law

and to the extent otherwise permissible in light of any Legal Impediment or required Consent and/or Governmental Approval, Newco shall be entitled to, and shall be responsible for, the management and the benefits and burdens of any Delayed Transfer Asset or any Delayed Transfer Liability not yet transferred to or assumed by it as a result of this Section 2.09(b) and the parties hereto agree to use reasonable best efforts to cooperate and coordinate with respect thereto.

(c) If and when the Legal Impediments and the Consents and/or Governmental Approvals, the failure to remove or the absence of which caused the deferral of the transfer or assumption of any Newco Asset or Newco Liability pursuant to Section 2.01(c), are removed or obtained, as the case may be, the transfer and assumption of the applicable Newco Asset or Newco Liability shall be promptly effected in accordance with the terms of this Agreement and/or the other applicable Transaction Documents, without the payment of additional consideration. After the Distribution Date, subject to Section 2.09(d), Weyerhaeuser and Newco agree to, and shall cause their respective subsidiaries to, use reasonable best efforts to remove such Legal Impediments and obtain such Consents and/or Governmental Approvals as promptly as practicable.

(d) The member of the Weyerhaeuser Group retaining a Delayed Transfer Asset or Delayed Transfer Liability due to the deferral of the transfer or assumption of such Newco Asset or Newco Liability pursuant to Section 2.01(c) shall not be obligated, in connection with this Section 2.09, to expend any money unless the necessary funds are advanced by Newco, other than reasonable out-of-pocket expenses, attorneys’ fees and recording or similar fees, all of which shall be promptly reimbursed by Newco. Any member of the Spinco Group holding an Excluded Asset or a Retained Liability improperly transferred to or assumed by the Spinco Group shall not be obligated, in connection with the foregoing, to expend any money unless the necessary funds are advanced by Weyerhaeuser, other than reasonable out-of-pocket expenses, attorneys’ fees and recording or similar fees, all of which shall be promptly reimbursed by Weyerhaeuser.

To the extent Newco makes any payment with respect to any liability of Weyerhaeuser or Weyerhaeuser Canada for which Weyerhaeuser or Weyerhaeuser Canada would be entitled to indemnification or reimbursement under the Bowater Agreement, Newco shall be subrogated to the maximum extent permitted by applicable Law to all rights of Weyerhaeuser and Weyerhaeuser Canada to indemnification and reimbursement under the Bowater Agreement with respect to such liability, and Weyerhaeuser or Weyerhaeuser Canada shall promptly pay to Newco the proceeds received by Weyerhaeuser or Weyerhaeuser Canada from any claims for indemnification or reimbursement under the Bowater Agreement. The foregoing shall not apply to any

liabilities and obligations with respect to the Bowater Claim, which is expressly excluded from this Section 2.09.

SECTION 2.10. Separation of Contractual Arrangements. (a) Weyerhaeuser and Newco shall in good faith negotiate and use commercially reasonable efforts to enter into a joint purchase agreement with respect to the Contracts that are set forth on Schedule 2.10(a).

Notwithstanding the foregoing, no Disabled Newco Employee shall be transferred to any member of the Spinco Group other than in accordance with Section 6.09(a)(ii) of the Transaction Agreement. The parties agree that no employee (other than the new hires referenced in clause (e) above) who is not engaged in the Newco Business will be a Transferred Employee. For purposes of this Section 2.11, “Mill Employee” means any Newco Employee employed by Weyerhaeuser or a Weyerhaeuser Subsidiary at the Transferred Real Property immediately prior to the Distribution Date (including any individuals who are not actively at work on the Distribution Date due to vacation, holiday, illness, jury duty, bereavement leave or other authorized leave of absence, Disabled Newco Employees, except to the extent contemplated in Sections 6.09(a)(ii) of the Transaction Agreement and U.S. WC Newco Employees, except to the extent contemplated in Section 6.09(a)(iii) of the Transaction Agreement).

(d) Retiree Benefits. Notwithstanding any provision of this Agreement to the contrary, following the Distribution, if Spinco or any affiliate of Spinco negotiates any changes in benefit levels or cost sharing that increase the retiree benefits for Canadian Newco Employees under a collective bargaining agreement, Spinco shall ensure that such changes will not apply to any persons who retired prior to the Distribution Date. In the event that, notwithstanding the preceding limitation or anything to the contrary in this Agreement, Spinco or any affiliate of Spinco negotiates any changes in benefit levels or cost sharing that increase the retiree benefits under a collective bargaining agreement for Canadian Newco Employees who do not become Transferred Employees and who retired prior to the Distribution Date, Spinco shall promptly reimburse Weyerhaeuser for all costs, expenses or liabilities resulting from such increase and shall indemnify and hold harmless Weyerhaeuser and all its affiliates for any Liabilities arising in connection therewith.

(b) From and after the Distribution Date, Weyerhaeuser shall guarantee the due and complete performance by Weyerhaeuser Canada and Weyerhaeuser Saskatchewan of their respective obligations under Section 4.04(a).

SECTION 4.06. Indemnification Procedures. (a) Procedures Relating to Indemnification of Third Party Claims. If any party (the “Indemnified Party”) receives written notice of the commencement of any action or proceeding or the assertion of any claim by a third party or the imposition of any penalty or assessment for which indemnity may be sought under Section 4.02, 4.03, 4.04 or 4.05 (a “Third Party Claim”), and such Indemnified Party intends to seek indemnity pursuant to this Article IV, the Indemnified Party shall promptly provide the other party (the “Indemnifying Party”) with written notice of such Third Party Claim, stating the nature, basis and the amount thereof, to the extent known, along with copies of the relevant documents evidencing such Third Party Claim and the basis for indemnification sought. Failure of the Indemnified Party to give such notice will not relieve the Indemnifying Party from liability on account of this indemnification, except if and to the extent that the Indemnifying Party is materially prejudiced thereby. The Indemnifying Party will have 30 days from receipt of any such notice of a Third Party Claim to give notice to assume the defense thereof. If notice to the effect set forth in the immediately preceding sentence is given by the Indemnifying Party, the Indemnifying Party will have the right to assume the defense of the Indemnified Party against the Third Party Claim with counsel of its choice; provided, however, that such counsel is reasonably satisfactory to the Indemnified Party; provided, further, however, that in the event the Indemnifying Party assumes the defense of any Third Party Claim it shall actively pursue such defense in good faith. If the Indemnifying Party does not assume the defense of such Third Party Claim within 30 days of receipt of such notice, the Indemnified Party against which such Third Party Claim has been asserted will have the right to assume the defense thereof, at its sole cost and expense, upon delivery of notice to such effect to the Indemnifying Party; provided, however, that if the Indemnifying Party at any time thereafter agrees to assume the defense of such Third Party Claim, the Indemnifying Party shall bear the reasonable fees, costs and expenses of the Indemnified Party’s counsel incurred prior to the time of the Indemnifying Party’s assumption of such defense. So long as the Indemnifying Party has assumed the defense of the Third Party Claim in accordance herewith, (i) the Indemnified Party may retain separate co-counsel at its sole cost and expense and participate in the defense of the Third Party Claim, (ii) the Indemnified Party will not file any papers or consent to the entry of any judgment or enter into any settlement with respect to the Third Party Claim without the prior written consent of the Indemnifying Party and (iii) the Indemnifying Party will not (A) admit to any wrongdoing or (B) consent to the entry of

any judgment or enter into any settlement with respect to the Third Party Claim to the extent such judgment or settlement provides for (x) relief other than money damages or (y) money damages if the Indemnifying Party has not acknowledged in writing that it shall be responsible for such money damages, in each case, without the prior written consent of the Indemnified Party (which consent shall not be unreasonably withheld or delayed). The parties will use their reasonable best efforts to minimize Losses from Third Party Claims and will act in good faith in responding to, defending against, settling or otherwise dealing with such claims. The parties will also cooperate in any such defense and give each other reasonable access to all information relevant thereto. Whether or not the Indemnifying Party has assumed the defense, such Indemnifying Party will not be obligated to indemnify the Indemnified Party hereunder for any settlement entered into or any judgment that was consented to without the Indemnifying Party’s prior written consent.

(b) Procedures for Non-Third Party Claims. The Indemnified Party will notify the Indemnifying Party in writing promptly of its discovery of any matter that does not involve a Third Party Claim giving rise to the claim of indemnity pursuant hereto. The failure so to notify the Indemnifying Party shall not relieve the Indemnifying Party from liability on account of this indemnification, except only to the extent that the Indemnifying Party is materially prejudiced thereby. The Indemnifying Party will have 30 days from receipt of any such notice to give notice of dispute of the claim to the Indemnified Party. The Indemnified Party will reasonably cooperate and assist the Indemnifying Party in determining the validity of any claim for indemnity by the Indemnified Party and in otherwise resolving such matters. Such assistance and cooperation will include providing reasonable access to and copies of information, records and documents relating to such matters, furnishing employees to assist in the investigation, defense and resolution of such matters and providing legal and business assistance with respect to such matters.

SECTION 4.07. Indemnification as Sole and Exclusive Remedy. Subject to Section 4.09(a), Weyerhaeuser, Spinco and Newco acknowledge and agree that, should the Distribution occur, Weyerhaeuser’s, Weyerhaeuser Canada’s, Weyerhaeuser Saskatchewan’s, Spinco’s, Newco’s and Newco Canada Exchangeco’s sole and exclusive remedy with respect to any and all claims relating to this Agreement, the Newco Business, the Newco Assets, the Excluded Assets, the Newco Liabilities, the Retained Liabilities, the Newco Canada Exchangeco Assets, the Canadian Excluded Assets, the Newco Canada Exchangeco Liabilities, the Canadian Retained Liabilities or the transactions contemplated by this Agreement and the Ancillary Agreements shall be pursuant to the indemnification provisions set forth in this Article IV. In furtherance of the foregoing and subject to the indemnification provision set forth in this Article IV, Weyerhaeuser, Spinco and Newco hereby waive, from and after the Distribution Date, any and all rights, claims and causes of action Weyerhaeuser or any other Weyerhaeuser Indemnitee, on the one hand, and Spinco or any other Spinco Indemnitee, on the other hand, may have against Spinco or any of its affiliates or, respectively, Weyerhaeuser or any of its affiliates, or their respective directors, officers and employees arising under or based upon any Federal, state, provincial, local or foreign statute, law, ordinance, rule or regulation or otherwise (including with respect to environmental matters generally and

any matters under the Comprehensive Environmental Response, Compensation, and Liability Act). This Section 4.07 will not apply to any breach following the Effective Time of the Transaction Agreement, the Tax Sharing Agreement, the Intellectual Property License Agreement, the Site Services Agreements, the Fiber Supply Agreements and the Transition Services Agreement.

SECTION 4.08. Calculation of Indemnity Payments. The amount of any Loss for which indemnification is provided under this Article IV shall be net of any amounts recovered by the Indemnified Party under insurance policies or underground storage tank reimbursement programs, with respect to such Loss and shall be (a) increased to take account of any net Tax cost actually incurred by the Indemnified Party arising from the receipt of indemnity payments hereunder (grossed up for such increase) and (b) reduced to take account of any net Tax benefit actually realized by the Indemnified Party arising from the incurrence or payment of any such indemnified amount. In computing the amount of any such Tax cost or Tax benefit, the Indemnified Party shall be deemed to recognize all other items of income, gain, loss, deduction or credit before recognizing any item arising from the receipt of any indemnity payment hereunder or the incurrence or payment of any indemnified amount. For purposes of indemnification under Sections 4.02 and 4.04, the amount of any Loss shall be reduced to the extent of any related “current liability” in the Statement (as fully resolved).

SECTION 4.09. Additional Matters. (a) Notwithstanding anything to the contrary in this Agreement, indemnification for Tax matters shall be governed by the terms, provisions and procedures of the Tax Sharing Agreement and not by this Article IV.

(b) In no event shall an Indemnifying Party be liable for special, punitive, exemplary, incidental, consequential or indirect damages, or lost profits, whether based on contract, tort, strict liability, other law or otherwise other than in the case of Third Party Claims.

ARTICLE V

The obligations of Weyerhaeuser pursuant to this Agreement to effect the Contribution and the Distribution shall be subject to the fulfillment (or waiver by Weyerhaeuser), at or prior to the Contribution Date, of the condition that each of the parties to the Transaction Agreement shall have irrevocably confirmed to each other that each condition in Article VII of the Transaction Agreement to such parties’ respective obligations to effect the transactions contemplated thereby have been fulfilled or shall be fulfilled at the Effective Time or are or have been waived by such party, as the case may be.

Certain Other Matters

SECTION 6.01. Rights Under Weyerhaeuser Insurance Policies. (a) Weyerhaeuser shall, and shall cause its subsidiaries to, keep all insurance policies currently maintained with respect to the Newco Assets, the Newco Canada Exchangeco Assets and the Newco Business (the “Weyerhaeuser Insurance Policies”), or suitable replacements therefor, in full force and effect through the close of business on the Distribution Date. Spinco and Newco acknowledge that any and all Weyerhaeuser Insurance Policies are owned and maintained by Weyerhaeuser or any member of the Weyerhaeuser Group (and not the Newco Business) and are Excluded Assets. Subject to Section 6.01(b), Spinco and Newco will not have any rights under the Weyerhaeuser Insurance Policies from and after the Distribution Date.

(b) If any Newco Asset, any Newco Canada Exchangeco Asset or the Newco Business suffers or has suffered any damage, destruction or other casualty loss or any Assumed Liability or Newco Canada Exchangeco Liability that is insured under the Weyerhaeuser Insurance Policies and arises or has arisen prior to the Distribution Date (but, in the case a loss arising from damage, destruction or other casualty loss to any Newco Asset or any Newco Canada Exchangeco Asset, after March 25, 2006), Weyerhaeuser shall, or shall cause the appropriate member of the Weyerhaeuser Group to, (i) assert a claim under the appropriate Weyerhaeuser Insurance Policies, and (ii) (x) surrender to Newco after the Distribution Date any insurance proceeds received by Weyerhaeuser or any member of the Weyerhaeuser Group under any Weyerhaeuser Insurance Policy with respect to such damage, destruction, liability or loss, less any amount of cash or proceeds applied by Weyerhaeuser or any other member of the Weyerhaeuser Group to the physical restoration of such asset or payment of such liability, and (y) assign to Newco after the Distribution Date all rights of Weyerhaeuser or any member of the Weyerhaeuser Group with respect to any causes of action (other than the rights with respect to causes of actions under the Weyerhaeuser Insurance Policies, which are hereby expressly retained by Weyerhaeuser), whether or not litigation has commenced as of the Distribution Date, in connection with such damage, destruction, liability or loss; provided, however, that the amount of the insurance proceeds to be surrendered to Newco shall be reduced by the amount of any applicable deductibles and co-payment provisions or any payment, reinsurance or reimbursement obligations of Weyerhaeuser or any member of the Weyerhaeuser Group in respect thereof. During three years after the Distribution Date (or, if later, until the final resolution of any relevant claim relating to the Newco Business), Weyerhaeuser shall not and shall cause the other members of the Weyerhaeuser Group not to amend, terminate, buy-out, extinguish or otherwise modify its or their respective liability under any Weyerhaeuser

Insurance Policies in a manner that would adversely affect Newco’s rights pursuant to this Section 6.01(b); provided, however, that this sentence shall not require Weyerhaeuser to renew or keep from lapsing any Weyerhaeuser Insurance Policy.

SECTION 6.02. Registration Prior to the Distribution Date. (a) If required by applicable law, the parties shall use their reasonable best efforts to prepare and file with the Commission a registration statement under the Securities Act and each party shall use its reasonable best efforts to have such registration statement declared effective by the Commission as promptly as practicable after such filing and to keep such registration statement effective as long as necessary to consummate the Distribution. The parties shall use their reasonable best efforts to prepare and file with the Commission any necessary amendment or supplement to such registration statement.

(b) The parties hereto shall take all such actions as may reasonably be required or appropriate under federal or state securities or Blue Sky laws (and any comparable laws under any foreign jurisdiction) in connection with the transactions contemplated by this Agreement or any Ancillary Agreement.

(c) The parties shall cooperate in preparing, filing with the Commission and causing to become effective any registration statements or amendments thereto, if any, which are necessary or appropriate to reflect the establishment of, or amendments to, any employee benefit plans contemplated by Sections 6.08 and 6.09 of the Transaction Agreement requiring registration under the Securities Act.

SECTION 6.03. Financing Arrangements. Prior to the Distribution, Spinco shall enter into an agreement or agreements providing for the New Debt. Weyerhaeuser, Spinco and Newco shall participate in the preparation of all materials and presentations as may be reasonably necessary to secure funding pursuant to such agreement or agreements, including rating agency presentations necessary to obtain the requisite ratings needed to secure the New Debt. Notwithstanding anything to the contrary in this Agreement or any other Transaction Document, Spinco and Newco, jointly and severally, shall pay all third party costs and expenses incurred by any member of the Weyerhaeuser Group associated with the New Debt.

SECTION 6.04. Enforcement of Confidentiality Agreements. Weyerhaeuser shall not, and shall not permit any other member of the Weyerhaeuser Group to, waive or amend any confidentiality agreement between Weyerhaeuser or any other member of the Weyerhaeuser Group and any Person (other than any member of the Weyerhaeuser Group) to the extent such waiver or amendment adversely affects the confidentiality of information related to the Newco Business. At Spinco’s written request, Weyerhaeuser shall, and shall cause each other member of the Weyerhaeuser Group to, enforce in accordance with its terms any confidentiality agreement between Weyerhaeuser or any other member of the Weyerhaeuser Group and any Person (other than any member of the Weyerhaeuser Group) to the extent such agreement protects the confidentiality of information related to the Newco Business; provided, however, that no member of the Weyerhaeuser Group shall be obligated to expend any money in connection with this Section 6.04 unless the necessary funds are advanced by Spinco,

other than reasonable out-of-pocket expenses, which shall be promptly reimbursed by Spinco.

SECTION 6.05. Site Separation Requirements. The parties acknowledge and agree that the Newco Business includes only portions of the operations conducted at the Weyerhaeuser facilities located in Plymouth, North Carolina; Kamloops, British Columbia and Columbus, Mississippi. Weyerhaeuser will use reasonable best efforts to (i) secure any Governmental Approvals required for separation of these operations from the other operations conducted at these facilities as set forth on Schedule 6.05, subject to such modifications as may be required or requested by Governmental Entities, and (ii) accomplish the subdivision, in accordance with the Governmental Approvals, so as to be able to convey the fee interests in such subdivided portions to Newco. In addition, with respect to each such portion, the subdivision of which shall have been accomplished by the Contribution Date, to the extent that Schedule 6.05 provides for easements and/or operating agreements to be entered into in connection with the separation of the operations described in this Section 6.05, Weyerhaeuser or the applicable member(s) of the Weyerhaeuser Group and Newco will execute and deliver such agreements on the Contribution Date. Notwithstanding the foregoing, to the extent that Weyerhaeuser has not accomplished the subdivision required for the conveyance of fee interests in the applicable portions of one or more of these facilities to Newco on the Contribution Date, (a) Weyerhaeuser or the applicable member(s) of the Weyerhaeuser Group and Newco, on the Contribution Date, will enter into interim net leases, under the terms set forth in Schedule 6.05, leasing to Newco the applicable portions of each of such facilities for which the subdivision has not been accomplished by the Contribution Date, pending the obtaining of such Governmental Approvals, it being the parties’ intent that the conveyance of the fee interest of the premises demised under each of such leases to Newco (with such modifications as may be required by the Governmental Entities in granting such Governmental Approvals) shall occur promptly after the accomplishment of the applicable subdivision, and (b) to the extent that Schedule 6.05 provides for easements and/or operating agreements to be entered into in connection with the separation of the operations at such facilities, Weyerhaeuser or the applicable member(s) of the Weyerhaeuser Group and Newco shall, in lieu of causing such agreements to be executed and delivered on the Contribution Date, arrange for the easements and/or services to be provided to Newco on an interim basis under the Transition Services Agreement or otherwise pending conveyance of fee interests in the premises demised under such leases to Newco, until the conveyance of such fee interests. Newco will cooperate with Weyerhaeuser in connection with the separation of the operations at the facilities and Weyerhaeuser’s efforts to secure the Governmental Approvals described in this Section 6.05.

ARTICLE VII

Additional Covenants

SECTION 7.01. Agreement for Exchange of Information; Archives. (a) Following the Distribution Date, for so long as such information is retained by a party or any of its subsidiaries (which shall be for a period of at least four years), upon

reasonable written notice, each party shall afford or cause to be afforded to the other party and its agents, representatives and auditors reasonable access to the personnel, properties, books, systems, Contracts, and Records (including financial records) relating to the Newco Business for any reasonable business purpose, including in respect of litigation, insurance matters and financial reporting of such party and its affiliates, including by, as and when reasonably requested by the other party, providing copies of any the foregoing books, systems, Contracts and Records (including financial records) related to the Newco Business to the other party; provided, that the party requesting such access agrees to reimburse the other party promptly for all reasonable and necessary out-of-pocket costs and expenses incurred in connection with any such request. Notwithstanding the foregoing, a party will not be required to disclose any information (i) which such party is prohibited from disclosing by a confidentiality agreement with a third party if such party has used reasonable best efforts to obtain the consent of the third party to such disclosure (it being understood that no party shall be obligated to pay any consideration to any third party from whom such consent is requested), or (ii) which would constitute privileged attorney-client communications or attorney work product, the transfer of which or the provision of access to which would, as reasonably determined by such party’s counsel, constitute a waiver of any such privilege. If any material is withheld by a party pursuant to the immediately preceding sentence, such party shall inform the other party as to the general nature of what is being withheld. Weyerhaeuser may redact such portions of any books and records (including any Records and Transferred Records) that do not relate to the Newco Assets, the Newco Canada Exchangeco Assets, the Newco Liabilities, the Newco Canada Exchangeco Liabilities or the Newco Business.

(b) After the Distribution Date, except in the case of an Action by one party against another party, each party hereto shall use its reasonable best efforts to make available to each other party, upon written request, the former, current and future directors, officers, employees, other personnel and agents of members of the Newco Business as witnesses, to the extent that any such Person (giving consideration to business demands of such directors, officers, employees, other personnel and agents) may reasonably be required in connection with any Action in which the requesting party may from time to time be involved, regardless of whether such Action is a matter with respect to which indemnification may be sought hereunder. The requesting party shall bear all costs and expenses in connection therewith.

SECTION 7.02. Further Assurances. From time to time, as and when requested by any party, each party shall execute and deliver, or cause to be executed and delivered, all such documents and instruments and shall take, or cause to be taken, all such further or other actions, as such other party may reasonably deem necessary or desirable to consummate the transactions contemplated by this Agreement and the Ancillary Agreements.

SECTION 7.03. No Use of Certain Retained Names. Newco shall, and shall cause its subsidiaries to, promptly, and in any event (a) within 60 days after the Distribution Date, make all necessary filings and take all other necessary actions to discontinue any references to the Retained Names, (b) within 180 days after the

Distribution Date, to revise print advertising, product labeling and all other information or other materials, including any Internet or other electronic communications vehicles, to delete all references to the Retained Names and (c) within 180 days after the Distribution Date, to change signage and stationery and otherwise discontinue use of the Retained Names. In no event shall Newco or any of its subsidiaries use any Retained Names after the Distribution in any manner or for any purpose different from the use of such Retained Names by Weyerhaeuser or any of its subsidiaries during the 90-day period preceding the Distribution Date. With respect to the Transferred Inventory, Newco may continue to sell such inventory, notwithstanding that it or its labeling or packaging bears one or more of the Retained Names, for 12 months after the Distribution. None of the foregoing provisions of this Section 7.03 shall be construed to obligate Newco to require any wholesaler, retailer or other merchant or customers of the Newco Business to conduct themselves in accordance therewith. After the Distribution Date, Newco shall file applications to amend or terminate any certificate of assumed name or d/b/a filings, within 60 days after Newco shall have become aware of such assumed name or d/b/a filing so as to eliminate the right of Newco to use the Retained Names.

SECTION 7.04. Permits. Weyerhaeuser, Spinco and Newco shall use their reasonable best efforts to obtain, or to cause to be obtained, a Permit for Newco or Newco Canada Exchangeco or a subsidiary of Newco Canada Exchangeco with respect to each Permit currently used by Weyerhaeuser, Weyerhaeuser Canada or Weyerhaeuser Saskatchewan in connection with the operation of, the Newco Business that is not transferred pursuant to Section 2.02(a)(vii) or pursuant to the Canadian Purchase Agreement; provided, however, that Weyerhaeuser shall not be obligated to pay any consideration to any third party or Governmental Entity from whom such Permits are requested under this Section 7.04.

SECTION 7.05. Removal of Certain Property. If the containerboard machine (and related old corrugated container assets) set forth on Schedule 2.02(b)(i) have not been removed from the facility located in Plymouth, North Carolina, prior to the Distribution Date, Newco shall allow Weyerhaeuser to have reasonable access to such facility after the Distribution Date for the purpose of removing such machine and related assets. Weyerhaeuser shall bear all costs of such removal and shall reimburse Newco for the reasonable costs of repairing any damage to the facility caused by such removal and shall reimburse Newco for any other reasonable expenses Newco may incur in connection with such removal (including the reasonable cost of any work stoppage at such facility caused by such removal). Weyerhaeuser shall complete the asset removals provided under this Section 7.05 within one year of the Distribution Date.

SECTION 7.06. Covenant Not to Compete. (a) In consideration of the mutual covenants provided for in this Agreement and the other Transaction Documents and other good and valuable consideration to be delivered to Weyerhaeuser and its shareholders in connection with the transactions contemplated hereby or thereby (the sufficiency of which is hereby acknowledged), during the period beginning on the Distribution Date and ending on the third year anniversary of the Distribution Date, Weyerhaeuser shall not, and shall cause each of its subsidiaries not to, directly or indirectly, engage in activities or businesses, or establish any new businesses, within

North America that are substantially in competition with the uncoated free sheet operations (including uncoated free sheet converting operations) and the forms operations included in the Newco Business as conducted on the Distribution Date (“Competitive Activities”); provided, however, that:

(i) this Section 7.06(a) shall be deemed not breached as a result of the ownership by Weyerhaeuser or any of its subsidiaries of: (A) any other securities (other than 20% or more of stock having general voting power in the election of directors (or securities exchangeable for such stock)) of a Person (other than a subsidiary of Weyerhaeuser) engaged, directly or indirectly, in Competitive Activities; or (B) any securities of a Person (other than a subsidiary of Weyerhaeuser) that engages, directly or indirectly, in Competitive Activities if, at the time such securities are acquired, such Competitive Activities account for less than 10% of such Person’s consolidated annual revenues;

(ii) nothing contained in this Section 7.06(a) shall prohibit or restrict (A) activities or businesses of Weyerhaeuser or any of its subsidiaries related to the Excluded Assets, (B) the sale of goods and services produced by or related to the Excluded Assets, or (C) subject to Section 7.06(a)(i), any restructuring or sale of any of the Excluded Assets; and

(iii) nothing contained in this Section 7.06(a) shall prohibit or restrict Weyerhaeuser or any of its subsidiaries from being acquired after the Distribution Date by a non-affiliated third Person which prior to such acquisition conducted Competitive Activities in North America.

(b) The parties agree that the covenants included in this Section 7.06 are, taken as a whole, reasonable in their geographic and temporal coverage, and no party shall raise any issue of geographic or temporal reasonableness in any proceeding to enforce such covenant; provided, however, that if the provisions of this Section 7.06 should ever be deemed to exceed the time or geographic limitations or any other limitations permitted by applicable Law in any jurisdiction, then such provisions shall be deemed reformed in such jurisdiction to the minimum extent required by applicable Law to cure such problem.

(c) The parties acknowledge and agree that in the event of a breach of the provisions of this Section 7.06, monetary damages shall not constitute a sufficient remedy. Consequently, in the event of any such breach, the non-breaching party may, in addition to any other rights and remedies existing in its favor, apply to any court referred to in Section 9.09 for specific performance and/or preliminary and final injunctive relief or other relief to enforce or prevent any violation of the provisions hereof.

SECTION 7.07. Cooperation with respect to Quarterly Reports. Following the Distribution Date, Weyerhaeuser shall cooperate, and shall request its independent accountants to cooperate, with Spinco in providing information for the preparation of any reports that are required to be filed by Spinco with the SEC pursuant to Section 13 or 15(d) of the Exchange Act with respect to any fiscal quarter up to and

including the fourth complete fiscal quarter following the Distribution Date. Notwithstanding anything to the contrary in the Transaction Documents, Spinco shall pay all fees and expenses of Weyerhaeuser’s independent accountants and Weyerhaeuser’s reasonable expenses in connection with the preparation of such reports. Spinco and Newco, jointly and severally, shall indemnify, defend and hold harmless Weyerhaeuser from and against any and all Losses, under the Exchange Act or otherwise, in connection with such quarterly reports except to the extent arising or resulting from information provided by Weyerhaeuser for inclusion in such reports that is inaccurate or incomplete in any material respect.

SECTION 7.08. Canadian Asset Sale Structure. The parties shall use reasonable best efforts to cause the Canadian Asset Sale to be structured in the most mutually Tax-efficient manner; provided, however, that no party will be required to agree to a structure that would reasonably be expected to increase costs, expenses or liabilities expected to be incurred by such party in connection with the transactions contemplated by the Transaction Documents.

EXCEPT AS MAY EXPRESSLY BE SET FORTH IN THIS AGREEMENT, THE CONTRIBUTION AND DISTRIBUTION AGREEMENT OR ANY ANCILLARY AGREEMENT, (A) LICENSOR MAKES NO REPRESENTATION OR WARRANTY OF ANY KIND WHATSOEVER, EXPRESS OR IMPLIED, WITH RESPECT TO THE LICENSE OF ANY RETAINED LICENSED INTELLECTUAL PROPERTY, (B) ALL OF THE RETAINED LICENSED INTELLECTUAL PROPERTY TO BE LICENSED IN ACCORDANCE WITH THIS AGREEMENT, THE CONTRIBUTION AND DISTRIBUTION AGREEMENT OR ANY ANCILLARY AGREEMENT SHALL BE LICENSED ON AN “AS IS, WHERE IS” BASIS, AND ALL IMPLIED WARRANTIES AS TO THE VALIDITY OR NON-INFRINGEMENT OF THE RETAINED LICENSED INTELLECTUAL PROPERTY AND AS TO THE ADEQUACY OF THE RETAINED LICENSED INTELLECTUAL PROPERTY FOR THEIR PURPOSE ARE HEREBY EXPRESSLY DISCLAIMED, AND (C) NONE OF THE PARTIES HERETO OR ANY OTHER PERSON MAKES ANY REPRESENTATION OR WARRANTY WITH RESPECT TO ANY INFORMATION, DOCUMENTS OR MATERIAL MADE AVAILABLE IN CONNECTION WITH THE ENTERING INTO OF THIS AGREEMENT, THE CONTRIBUTION AND DISTRIBUTION AGREEMENT, ANCILLARY AGREEMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.

SECTION 7. Registration and Maintenance. (a) Licensor and Licensee will use commercially reasonable efforts to protect the Retained Licensed Technology as trade secrets. Licensor will use commercially reasonable efforts to maintain the Retained Licensed Patents and the Retained Licensed Copyrights (collectively, the “Registerable Intellectual Property”) and all registrations thereof and/or applications therefor. Licensee will execute all documents as are reasonably necessary or expedient to aid in, and will otherwise cooperate at Licensor’s expense with, Licensor’s efforts to prepare, obtain, file, record and maintain all such registrations and applications. (b) To the extent Licensor has not registered any Registerable Intellectual Property, Licensee may, at its own expense, register such Registerable Intellectual Property, in the name of, and on behalf of, Licensor provided that (x) Licensee gives written notice of its intention to register such Registerable Intellectual Property, and (y) within 30 days of such notice, (i) Licensor does not object to Licensee registering such Registerable Intellectual Property or (ii) Licensor fails to register such Registerable Intellectual Property. (c) To the extent Licensor has

B-3

not maintained or does not intend to maintain any registrations or applications for Registerable Intellectual Property, Licensee may, at its own expense, make such filings as are necessary to maintain any registrations or applications therefor, in the name of, and on behalf of, Licensor. Licensor will give notice to Licensee as soon as it decides not to maintain any such registrations or applications but in any event not less than 60 days before such filings are due. Within 30 days of Licensee’s receipt of such notice, Licensee will give notice to Licensor whether it will or will not make such filings. Licensor will execute all documents as are reasonably necessary or expedient to aid in, and will otherwise cooperate at Licensee’s expense with, Licensee’s efforts to prepare, obtain, file, record and maintain all such registrations and applications.

SECTION 8. Infringement Actions.

(a) Licensor will from time to time take all steps that it considers (in its sole discretion) necessary to protect Licensor’s and Licensee’s rights in and to the Retained Licensed Intellectual Property (other than the Solaia Patents and the Lemelson Patents), and Licensee agrees forthwith to communicate to Licensor any infringements or misappropriations or threatened infringements or misappropriations of any such rights of Licensor which may come to its notice and, at Licensor’s expense, to do all and any such acts as Licensor may reasonably require for preventing such infringements or misappropriations or threatened infringements or misappropriations. In the event Licensor takes affirmative action against an infringement or misappropriation, Licensee agrees to assist Licensor in whatever manner Licensor reasonably requests, at the expense of Licensor. Recovery of damages resulting from any such action shall be solely for the account of Licensor. Licensee will provide information reasonably requested by Licensor in any infringement or misappropriation action, including in connection with the calculation of damages. Licensee may participate, at its expense, in any action taken by or proceeding instituted by or brought against Licensor through separate counsel of Licensee’s own choosing; provided that Licensor will at all times retain full control over such action.

(b) Licensor will use reasonable efforts to enforce Licensor’s contractual or other confidentiality rights against an individual employee to the extent that such rights relate to an unauthorized disclosure or use of Retained Licensed Technology after the individual has left the employment of Licensor. If, in the case of such an unauthorized disclosure or use of any Retained Licensed Technology by an individual who becomes a former employee of Licensor, Licensee (a) determines to take action against such an individual, whether by commencing a proceeding or otherwise, and (b) requests that Licensor join such action by enforcing Licensor’s rights against such individual, Licensor will enforce such rights and otherwise provide reasonable cooperation to Licensee.

(c) Notwithstanding any limitations on Licensee’s rights to use any of the Retained Licensed Intellectual Property pursuant to Section 2, if (i) a third party is, in the reasonable opinion of Licensee, infringing or misappropriating any of such Retained Licensed Intellectual Property (other than the Solaia Patents and the Lemelson Patents) in a manner that is material to the Newco Business, (ii) Licensee notifies Licensor of such third party activities in accordance with Section 12, and (iii) Licensor does not take affirmative action either to prevent such activities or subject to Section 22, to license to such third party under the Retained Licensed Intellectual Property (other than the Solaia Patents and the Lemelson Patents) required for such activities, then Licensee’s ability to use such Retained Licensed Intellectual Property (other than

B-4

the Solaia Patents and the Lemelson Patents) is no longer subject to the restrictions set forth in Section 2 on the use of such Retained Licensed Intellectual Property (other than the Solaia Patents and the Lemelson Patents).

SECTION 9. Indemnification.

(a) Each party (the “Indemnifying Party”) shall indemnify and hold harmless and, at the other party’s sole option, defend, the other party and its affiliates and its and their respective officers, directors, employees, agents, advisers and representatives (the “Indemnified Parties”) from and against any and all claims, demands, liabilities, obligations, taxes, losses, fines, costs, expenses, royalties, litigation, deficiencies or damages (whether absolute, accrued, conditional or otherwise resulting from third-party claims), including interest and penalties with respect thereto and out-of-pocket expenses and reasonable attorneys’ and accountants’ fees and expenses incurred in the investigation or defense of any of the same or in asserting, preserving or enforcing any of their respective rights hereunder (collectively, “Losses”), resulting from or arising out of any claims or actions of third parties based on or arising out of any breach of any representation, warranty, covenant or obligation under this Agreement.

(b) In the event that any Indemnified Party elects to have the Indemnifying Party defend any claim or action of third parties referred to in Section 9(a), (i) such Indemnified Party will so notify the Indemnifying Party in writing, (ii) such Indemnified Party shall have the right to approve the Indemnifying Party’s counsel, which approval shall not unreasonably be withheld, and to obtain its own counsel at such Indemnified Party’s own expense and (iii) the Indemnifying Party shall obtain the approval of such Indemnified Party before entering into any compromise regarding such actions that would impose any liability or obligation on such Indemnified Party, which approval will not be unreasonably withheld. In the event that such Indemnified Party elects to defend any claim or action of third parties referred to in Section 9(a), the Indemnifying Party shall pay all reasonable attorney’s fees and expenses in connection with such defense. If any claim, demand, assessment or liability, or cost incidental thereto, is asserted against an Indemnified Party in respect of which the Indemnified Party proposes to demand indemnification from the Indemnifying Party pursuant to this Section 9, such Indemnified Party will promptly notify the Indemnifying Party in writing. No failure of an Indemnified Party to promptly notify the Indemnifying Party shall relieve the Indemnifying Party from the obligation to indemnify the Indemnified Party unless and to the extent the Indemnifying Party is actually prejudiced by such failure.

SECTION 10. Confidentiality. Each party agrees and will undertake to keep any information regarding the Retained Licensed Intellectual Property or otherwise received under this Agreement confidential and will refrain from disclosing it to any third party, unless (and to the extent) compelled to disclose by judicial or administrative process or, in the opinion of such party’s counsel, by the requirements of applicable law or regulations (including Securities and Exchange Commission rules and regulations), in which case the party seeking to disclose such information will give the other party reasonable advance notice of such disclosure in order to permit the other party to seek an appropriate protective order or to attempt to reach mutual agreement regarding the portions of such information that should be subject to a request for confidential treatment, and except to the extent that such information (a) is required to be disclosed by either party in order to carry out its rights or obligations hereunder, (b) is in the

B-5

public domain through no fault of the party to which it is furnished, including through prior public disclosure made in accordance with this Section 10, (c) is independently developed by the party to which it is furnished without use of, reference to, or reliance upon, the furnishing party’s information, as evidenced by written documentation, or (d) is later lawfully acquired from other sources (without obligations of confidentiality) by the party hereto to which it is furnished.

SECTION 11. No Third-Party Beneficiaries. This Agreement is for the sole benefit of the parties hereto and their permitted assigns and nothing herein expressed or implied shall give or be construed to give to any person, other than the parties hereto and such assigns, any legal or equitable rights hereunder.

SECTION 12. Notices. All notices, requests, permissions, waivers and other communications hereunder shall be in writing and shall be deemed to have been duly given (a) five business days following sending by registered or certified mail, postage prepaid, (b) when sent, if sent by facsimile; provided that the facsimile transmission is promptly confirmed by telephone, (c) when delivered, if delivered personally to the intended recipient and (d) one business day following sending by overnight delivery via a national courier service and, in each case, addressed to a party at the following address for such party:

or to such other address(es) as shall be furnished in writing by any such party to the other party to this Agreement in accordance with the provisions of this Section 12.

SECTION 13. Amendments. This Agreement may be amended, modified, superseded or canceled and any of the terms, covenants or conditions hereof may be waived only

B-6

by an instrument in writing signed by each of the parties hereto or, in the case of a waiver, by or on behalf of the party waiving compliance.

SECTION 14. Independent Contractors. The parties to this Agreement intend by this Agreement to enter into only a license agreement and this Agreement shall not in any way be deemed to establish any other relation between them. Neither Licensee, on the one hand, nor Licensor, on the other hand, shall be considered a partner, joint venturer, agent or other representative of the other for any purpose whatsoever and neither shall hold itself out as such. Neither Licensee, on the one hand, nor Licensor, on the other hand, nor any employee, officer, director or agent of either shall hold themselves out as an agent of the other party. Nothing in this Agreement shall be construed to grant either party any right or authority to assume or create any obligation on behalf or in the name of the other; to accept summons or legal process for the other; or to bind the other in any manner whatsoever.

SECTION 15. Severability; Enforcement. The invalidity of any portion of this Agreement shall not affect the validity, force or effect of the remaining portions hereof. If it is ever held that any restriction hereunder is too broad to permit enforcement of such restriction to its fullest extent, each party agrees that a court of competent jurisdiction may enforce such restriction to the maximum extent permitted by law, and each party hereby consents and agrees that such scope may be judicially modified accordingly in any proceeding brought to enforce such restriction.

SECTION 16. Integrated Contract; Schedule. This Agreement, including the Schedules hereto, any written amendments to the foregoing satisfying the requirements of Section 13 hereof, the Contribution and Distribution Agreement, the Ancillary Agreements and the Confidentiality Agreement, including the schedules, exhibits and annexes thereto, constitute the entire agreement among the parties with respect to the subject matter hereof and thereof and supersede any previous agreements and understandings between the parties with respect to such matters. The Schedules annexed to this Agreement are hereby incorporated in and made a part of this Agreement as if set forth in full herein. Any terms used in the Schedules but not otherwise defined therein shall be defined as set forth in this Agreement or the Contribution and Distribution Agreement, as the case may be. There are no restrictions, promises, representations, warranties, agreements or undertakings of any party to this Agreement with respect to the transactions contemplated by this Agreement, the Contribution and Distribution Agreement, the Ancillary Agreements or the Confidentiality Agreement other than those set forth herein or therein or in any other document required to be executed and delivered hereunder or thereunder. In the event of any conflict between the provisions of this Agreement (including the Schedules hereto), on the one hand, and the provisions of the Contribution and Distribution Agreement (including the schedules and exhibits thereto), on the other hand, the provisions of the Contribution and Distribution Agreement shall control.

SECTION 17. Counterparts. This Agreement may be executed in one or more counterparts, all of which shall be considered one and the same agreement, and shall become effective when one or more counterparts have been signed by each of the parties hereto and delivered, in person, by facsimile or by electronic image scan, receipt acknowledged in each case, to the other party hereto.

B-7

SECTION 18. Governing Law. This Agreement and any disputes arising under or related hereto (whether for breach of contract, tortious conduct or otherwise) shall be governed and construed in accordance with the laws of the State of New York, without reference to its conflicts of law principles.

SECTION 19. Jurisdiction. Each party irrevocably agrees that any legal action, suit or proceeding against them arising out of or in connection with this Agreement or the transactions contemplated by this Agreement or disputes relating hereto (whether for breach of contract, tortious conduct or otherwise) shall be brought exclusively in the United States District Court for the Southern District of New York, or, if such court does not have subject matter jurisdiction, the state courts of New York located in New York County and hereby irrevocably accepts and submits to the exclusive jurisdiction and venue of the aforesaid courts in personam, with respect to any such action, suit or proceeding.

SECTION 20. Service of Process. Each party agrees that service of any process, summons, notice or document by U.S. registered mail to such party’s respective address set forth above shall be effective service of process for any action, suit or proceeding in New York with respect to any matters for which it has submitted to jurisdiction pursuant to Section 19.

SECTION 21. Waiver of Jury Trial. Each party hereby waives to the fullest extent permitted by the laws of the State of New York, any right it may have to a trial by jury in respect of any litigation directly or indirectly arising out of, under or in connection with this Agreement or the transactions contemplated by this Agreement or disputes relating hereto. Each party (a) certifies that no representative, agent or attorney of any other party has represented, expressly or otherwise, that such other party would not, in the event of litigation, seek to enforce the foregoing waiver and (b) acknowledges that it and the other party hereto have been induced to enter into this Agreement by, among other things, the mutual waivers and certifications in this Section 21.

SECTION 22. Assignment; Sublicense. This Agreement and all rights and obligations of Licensee hereunder may not be assigned by Licensee or subject to a sublicense without the prior written consent of Licensor; provided, however, that Licensee may, without such consent, (a) grant sublicenses of any of the rights granted pursuant to Section 2, in each case to any current or future affiliate of Licensee but only so long as such affiliate remains an affiliate (in which case Licensee shall continue to be bound by the terms of this Agreement), or (b) (i) assign this Agreement to a purchaser or transferee of all or substantially all of the Newco Business or (ii) grant sublicenses of any of the rights granted pursuant to Section 2 for any facility or business that is part of the Newco Business to any purchaser or transferee of all or substantially all of such facility or business; provided that in each case the assignee or sublicensee agrees to be bound by the terms and conditions of this Agreement by executing an acknowledgement in the form and substance acceptable to Licensor. Licensor may not license any of the Retained Licensed Intellectual Property to any Person engaged in Competitive Activities (as defined in the Contribution and Distribution Agreement), including selling goods or services of the type sold by the Newco Business in North America, other than to (i) a current or future affiliate of Licensor or (ii) a purchaser or transferee of all or substantially all of any affiliate or facility of Licensor. Any transfer or other disposition by Licensor of any Retained Licensed Intellectual Property will be made subject to the terms of this Agreement and the

B-8

person or entity acquiring such Retained Licensed Intellectual Property from Licensor shall agree to be bound by the terms and conditions of this Agreement by executing an acknowledgement in form and substance acceptable to Licensee. The term “affiliate” used in this Agreement shall have the meaning given to such term in the Contribution and Distribution Agreement.

SECTION 23. Effectiveness. Notwithstanding anything to the contrary in this Agreement, this Agreement shall only become effective as of the Closing and shall not become effective if the Closing does not occur.

SECTION 24. Headings. The descriptive headings of the several Sections of this Agreement and the Schedule hereto are inserted for convenience only, do not constitute a part of this Agreement and shall not affect in any way the meaning or interpretation of this Agreement. All references in this Agreement to “Sections” or “Schedules” shall be deemed to be references to Sections of this Agreement or the Schedules hereto unless otherwise indicated.
