Eligible Offerees who accept an Offer as to all or any portion of the Shares Subject to the Offer shall evidence their acceptance by delivering, within 10 days after receipt of the notice pursuant to Section 4.2 from the Company, to the Offeror or other transferor a written notice of intent to purchase such Shares Subject to the Offer (“Acceptance Notice”). The closing of the acquisitions of Shares Subject to the Offer by Eligible Offerees shall be consummated within 30 days following the delivery of the Acceptance Notice. In the case of all acquisitions of Shares Subject to the Offer by Eligible Offerees, such acquisitions shall be consummated at a closing held at the principal offices of the Company (unless otherwise mutually agreed), at which time the Purchase Price (if cash, in the form of a cashier’s check) shall be delivered to the transferor of the Shares or the transferor’s representative and the transferor or the transferor’s representative shall deliver to the Eligible Offeree(s) purchasing such shares certificates representing all of the Shares Subject to the Offer, duly endorsed for transfer or accompanied by duly executed stock powers, evidence of good title to the Shares Subject to the Offer and the absence of liens, encumbrances and adverse claims with respect thereto and such other matters as

are necessary for the proper transfer of the Shares Subject to the Offer to the acquiring Eligible Offeree(s) on the securities register of the Company.

4.5 Form of Payment. The Purchase Price of any Shares Subject to the Offer purchased by Eligible Offerees pursuant to an Offer made under Section 3.1 shall be on such terms as contemplated by the Acquisition Proposal; provided, however, that if the party which has made the Acquisition Proposal has proposed to acquire Shares Subject to the Offer for consideration not wholly in cash, then any Eligible Offeree who desires to consummate the acquisition(s) of Shares Subject to the Offer (pursuant to the terms hereof) shall consummate such acquisition wholly in cash. In such a case, the Board shall determine the per share cash value of the Acquisition Proposal, and such amount shall be the cash price per share to be paid to the Offeror by any Eligible Offeree. The Purchase Price of all Shares Subject to the Offer pursuant to an Offer made under Sections 3.2 through 3.4 shall be paid in the form of a cashier’s check or such other form as is mutually acceptable.

5. Material Agreements. Notwithstanding anything herein to the contrary, no Holder shall make any Disposition of Shares (including but not limited to a Disposition pursuant to Sections 3 or 6 hereof) which, in the Company’s reasonable judgment (as evidenced by a resolution of the Board), would cause a material breach, event of default, default or acceleration of payments or which would require the Company to make any mandatory repurchase offer, mandatory repurchase, mandatory redemption or mandatory prepayment, under any loan agreement, note, indenture or other agreement or instrument to which the Company or any of its direct or indirect subsidiaries is a party and under which the indebtedness or liability of the Company or any of its direct or indirect subsidiaries exceeds $5 million (“Material Agreement”); provided, however, that the Company has the sole right to, and may in its discretion (as evidenced by a resolution of the Board), waive the application and requirements of this Section 5. Therefore, each Holder desiring or required to make a Disposition shall, prior to attempting to effect any such Disposition, (i) give written notice (which may be the Offer required under Section 3.1, the Divorce Notice under Section 3.2, the Passing Interest Notice under Section 3.3 or the notice by a Holder to the Company under Section 3.4, if applicable) (“Notice”) to the Company describing the proposed Disposition and the proposed transferee in sufficient detail, setting forth the number of Shares as to which such Holder desires or is required to make a Disposition, and (ii) provide such other information concerning the Disposition as the Company reasonably requests. If, in the Company’s reasonable judgment (as evidenced by a resolution of the Board), the proposed Disposition would cause a material breach, event of default, default or acceleration of payments or which would require the Company or any of its direct or indirect subsidiaries to make any mandatory repurchase offer, mandatory repurchase, mandatory redemption or mandatory prepayment, under any Material Agreement and the application of this Section 5 is not waived by the Company as provided above, then the Company within 20 days after receipt of the Notice, shall give written notice to such Holder of such determination, the proposed Disposition may not be made, and any attempt to make such Disposition shall be null and void; provided, however, that any such determination by the Company shall not prevent such Holder from making a subsequent Disposition to Eligible Offerees or third parties upon compliance with all of the terms and conditions of this Agreement with respect to such Disposition, including the terms and conditions of this Section 5. If the Company approves such Disposition and any Shares with respect to which approval has been given are not actually transferred within 60 days from the date of such approval, then all of the

provisions of this Agreement shall apply to any subsequent transaction affecting such Shares or any interest therein.

6. Permitted Dispositions. The following Dispositions shall be permitted without compliance with the provisions of Sections 3, 4 and 9; however, Sections 5 and 8 shall apply to the following Dispositions:

6.1 between Holders;

6.2 by any Holder to the Company;

6.3 by any Holder which is a trust, partnership, limited partnership, corporation or limited liability company to any entity that controls, or is controlled by, or is under common control with such Holder, or to any Holder from any entity that controls, or is controlled by, or is under common control with such Holder;

6.4 by any individual Holder during such Holder’s lifetime to any of such Holder’s Associates, provided that a Disposition to a Holder’s spouse under this Section 6.4 must be made during marriage and not incident to divorce; and provided further, that any such transferee as granted the voting rights to the transferring Holder required below;

6.5 to any individual Holder during such Holder’s lifetime by any of such Holder’s Associates; provided that a Disposition by a Holder’s spouse to such Holder under this Section 6.5 must be made during marriage and not incident to divorce;

6.6 upon the death of any individual Holder, to the estate, beneficiaries, heirs or legatees of such Holder;

6.7 by:

(i) any Holder at the then current Purchase Price, to any individual Person who becomes an employee of the Company or a direct or indirect majority-owned subsidiary of the Company at the Effective Date; provided that any such employee becomes a party to this Agreement as provided below and is not included in a Designated Holder Group;

(ii) any Holder at the then current Purchase Price to any individual Person who becomes a non-employee director of the Company or a direct or indirect majority-owned subsidiary of the Company at the Effective Date; provided that such individual Person becomes a party to this Agreement as provided below and is not included in a Designated Holder Group;

6.8 [Intentionally omitted];

6.9 by any Holder which is a trust, partnership, limited partnership, corporation or limited liability company to the record owners of such Holder, if any, or the beneficiaries of such Holder as a distribution pursuant to law, the governing instrument or charter of such Holder, or the dissolution of such Holder;

6.10 by any Holder in a public sale or public distribution pursuant to such Holder’s rights under any registration rights agreement to which the Company is a party;

6.11 by any Holder to any direct or indirect majority-owned subsidiary of the Company; and

6.12 pursuant to Sections 9 or 10;

provided, however, that as a condition precedent to any such permitted Disposition (i) (other than a Disposition pursuant to Sections 6.1, 6.2 or 6.11), any Person (including any such individual Person’s spouse, if any) intending to acquire the Shares to be Disposed of shall become a party to this Agreement by executing an Adoption Agreement in the form of Exhibit “A” attached hereto or in any other form having substantially the same effect satisfactory to the Company (an “Adoption Agreement”), whereupon such Person shall be deemed a “Holder,” and shall have all of the rights and obligations of a “Holder,” under this Agreement, and such Shares shall be subject to the provisions of this Agreement and (ii) with respect to a Disposition pursuant to Sections 6.4, such Adoption Agreement shall include the voting agreement provisions set forth in Section 5 of the form of Adoption Agreement in the form of Exhibit “A” attached hereto; provided, further, that notwithstanding the foregoing, a Holder may not make a Disposition to any Person if such Disposition is made with the intent and purpose of avoiding the restrictions on dispositions in this Agreement (it being understood that the purpose of this sentence is to prohibit any Disposition that is otherwise permitted by this Agreement but for which the transferring Holder intends at the time of such Disposition to effect a change in the relationship between the transferring Holder and such transferee after such Disposition with the intent and purpose that the transferring Holder will have indirectly made a Disposition which would not have been directly permitted under this Agreement had such change in such relationship occurred prior to such Disposition).

7. Additional Parties. If (i) required under Section 4.3, Section 4.4, Section 9 or any other provision of this Agreement, (ii) authorized by the Board, or (iii) approved by the Holders of the Required Two-Thirds Percentage, any Person that acquires any Shares after the Effective Date shall become a party to this Agreement by executing an Adoption Agreement, then such Person shall be deemed a “Holder,” and shall have all of the rights and obligations of a “Holder” under this Agreement, and such Shares shall be subject to the provisions of this Agreement. Any such Adoption Agreement executed by a Person who becomes a party to this Agreement pursuant to the authorization or approval described in the preceding sentence, if required as a condition to the authorization or approval, shall include the voting agreement provisions set forth in Section 5 of the form of Adoption Agreement attached hereto as Exhibit “A”.

8. Standstill Agreement; Securities Matters.

8.1 Standstill Agreement. At any time that the Company is engaged in an underwritten public offering of its securities (on its own behalf, on behalf of selling stockholders or both), no Holder will make any Disposition of Shares on any securities exchange or in the over-the-counter or any other public trading market for whatever period of time the Company (upon the recommendation of its underwriters) requests by written notice to each Holder; provided, however, that (i) such request shall not be for a period extending longer than 180 days after the later of (a) the

effective date of the registration statement relating to such public offering, and (b) the date of the underwriting agreement relating to such public offering; (ii) this Section 8.1 shall not limit any Holder’s right to include Shares in any such underwritten public offering pursuant to any demand or piggyback registration rights that such Holder may have pursuant to any registration rights or similar agreement binding upon the Company; and (iii) all Holders are subject to the same request to restrict Dispositions. The obligations in this Section 8 shall survive the termination of this Agreement for 180 days after the Initial Public Offering, after which time the obligations in this Section 8 shall terminate.

8.2 Securities Laws. No Holder shall make any Disposition of any Shares at any time if such action would constitute a violation of any federal or state securities or blue sky laws or a breach of the conditions to any exemption from registration or any prospectus exemption in respect of the Shares under any such laws or a breach of any undertaking or agreement of a Holder entered into pursuant to such laws or in connection with obtaining an exemption thereunder. Except for transfers pursuant to an effective registration statement or pursuant to Rule 144 under the Securities Act, the Company shall not transfer any Shares on its securities register unless prior thereto the Company shall have received (unless waived by the Company) an unqualified written opinion of legal counsel, which counsel and opinion (in form and substance) shall be reasonably satisfactory to the Company, to the effect that the proposed Disposition is in compliance with this Section 8.2. Each Holder agrees that any certificates representing Shares shall bear appropriate legends restricting the sale or other transfer of such Shares in accordance with applicable federal or state securities or blue sky laws and in accordance with the provisions of this Agreement. This Section 8.2 shall survive termination of this Agreement for the maximum period permitted by applicable law.

9. Right of Participation in Dispositions. An Offeror required to make an Offer under Section 3.1 upon receipt of an Acquisition Proposal shall give written notice (“Disposition Notice”) to all other Holders providing each other Holder with the right to elect (by written notice to the Offeror before the expiration of the Election Period) to Dispose of, at the same price and on the same terms that the beneficial ownership of the Offeror’s Shares are to be transferred pursuant to the Acquisition Proposal or to the Eligible Offerees to whom such Offer is made under Section 3.1, a number of Shares held by such other Holder equal to the number of outstanding Shares proposed to be included in such Disposition by the Offeror multiplied by a fraction, the numerator of which is the number of Shares owned by such other Holder and the denominator of which is the aggregate number of outstanding Shares owned by all Holders (including the Offeror) electing to include Shares in such Disposition. No such Holder (other than the Offeror) who elects to Dispose of Shares pursuant to a Disposition Notice under this Section 9 shall be required to comply with Section 3.1 with respect to such Disposition.

If any other Holder or Holders have elected to Dispose of Shares pursuant to a Disposition Notice under this Section 9, the Offeror shall reduce to the extent necessary the number of the Offeror’s Shares it otherwise would have Disposed of pursuant to the Acquisition Proposal so as to permit other Holders who have elected to participate in such Disposition to sell the number of Shares they are entitled to sell under this Section 9, and the Offeror and such other Holder or Holders shall sell the number of Shares specified in the Acquisition Proposal to the proposed transferee in accordance with the terms of such sale as set forth in the Disposition Notice; provided, however, that if the proposed transferee deals solely with the Offeror and refuses to

purchase from the other Holders who have elected to participate in the Disposition pursuant to this Section 9, then (i) the Offeror shall be entitled to sell up to the number of Shares specified in the Acquisition Proposal to the proposed transferee in accordance with the terms of such sale as set forth in the Disposition Notice and (ii) the Offeror shall contemporaneously therewith purchase from such other Holders who have elected to participate in such Disposition, on the terms set forth in the Disposition Notice, up to the number of Shares that they would have been entitled to sell to the proposed transferee under this Section 9 had the proposed transferee purchased such Shares directly from such Holders in accordance with the terms of this Section 9. Any Holder other than the Offeror who participates in a Disposition under this Section 9 shall not be liable for any transaction costs associated with such a Disposition other than the legal costs incurred by that Holder and, if the Offeror is obligated to pay selling commissions, then a pro rata portion of such selling commissions.

The Company shall, if necessary, establish reasonable procedures, in addition to those specified herein, to implement the provisions of this Section 9. No Disposition may be made by the Offeror under this Section 9 unless, contemporaneously therewith, all Holders electing to participate in such Disposition receive the amounts to which they are entitled under this Section 9; provided, however, that no Holder shall be obligated in connection with such Disposition (i) to make any representation and warranty other than as to such Holder’s ownership of such Holder’s Shares and such Holder’s authority to execute the applicable purchase agreement and transfer such Shares or (ii) to indemnify the prospective transferee or its Associates with respect to an amount in excess of the cash proceeds paid to such Holder in connection with such Disposition; and any indemnity given by any Holder shall be several and not joint and no Holder shall be required to execute a non-compete agreement of any kind in connection with such Disposition. Each Holder transferring Shares pursuant to this Section 9 shall be obligated to join on a pro rata basis (based on the number of Shares to be sold) in any indemnification or other obligations that are part of the terms and conditions of such Disposition (other than any such obligations that relate specifically to a particular Holder, such as indemnification with respect to representations and warranties given by a Holder regarding such Holder’s title to and ownership of Shares). If all of the Shares Subject to the Offer that are the subject of the Disposition Notice are not purchased by the Eligible Offerees under Section 3.1 and the Disposition described in the Disposition Notice is not consummated in the manner described in the Disposition Notice within 90 days after the delivery of the Disposition Notice, such Disposition shall not be made and all of the provisions of this Agreement shall apply to any subsequent proposed Disposition by the Offeror. All Shares transferred in accordance with the terms of this Section 9 shall remain subject to the terms of this Agreement and the transferee(s) shall execute and deliver to the Company an Adoption Agreement as provided in Section 7.

10. Approved Sale.

10.1 Inclusion of Shares. Following the approval of an Approved Sale each Holder will (i) consent to and raise no objections against the Approved Sale or the process pursuant to which the Approved Sale was arranged, (ii) waive any dissenter’s rights and other similar rights, and (iii) if the Approved Sale is structured as a sale of Capital Stock, agree to sell such Holder’s Shares on the terms and conditions of the Approved Sale in accordance with this Section 10. Each Holder will take all necessary and desirable actions, in its, his or her capacity as a stockholder of the Company, as directed by the Holders who have approved the Approved Sale, in connection

with the consummation of any Approved Sale, including without limitation executing the applicable purchase agreement and granting identical indemnification rights (whether directly to the buyer of the Shares or pursuant to the provisions of a contribution agreement); provided, however, that no Holder shall be obligated in connection with the Approved Sale (i) to make any representation and warranty other than as to such Holder’s ownership of such Holder’s Shares and such Holder’s authority to execute the applicable purchase agreement and transfer such Shares or (ii) to indemnify the prospective transferee or its Associates with respect to an amount in excess of the cash proceeds paid to such Holder in connection with the Approved Sale; and any indemnity given by any Holder shall be several and not joint and no Holder who is included in a Designated Holder Group shall be required to execute a non-compete agreement of any kind in connection with such sale. Each Holder transferring Shares pursuant to this Section 10.1 shall be obligated to join on a pro rata basis (based on the number of Shares to be sold) in any indemnification or other obligations that are part of the terms and conditions of such Disposition (other than any such obligations that relate specifically to a particular Holder, such as indemnification with respect to representations and warranties given by a Holder regarding such Holder’s title to and ownership of Shares).

10.2 Purchaser Representative. If the Company or the holders of the Company’s securities enter into any negotiation or transaction for which Rule 506 under the Securities Act (or any similar law or rule of the United States or any state then in effect) may be available with respect to any Approved Sale transaction (including a merger, consolidation, plan of exchange, amalgamation, recapitalization, reorganization or other business combination), the Holders who are not accredited investors (as such term is defined in Regulation D under the Securities Act) will, at the request of the Company, appoint a purchaser representative (as such term is defined in Rule 501 under the Securities Act or any similar law or rule of the United States or any state then in effect) reasonably acceptable to the Company. If any Holder appoints a purchaser representative designated by the Company, the Company will pay the fees of such purchaser representative.

10.3 Participation. All Holders will bear their pro rata shares (based upon the relative amounts of proceeds received in such Approved Sale) of the reasonable costs of any sale of Shares pursuant to an Approved Sale to the extent such costs are incurred for the benefit of all selling Holders and are not otherwise paid by the Company or the acquiring party.

11. Preemptive Rights.

11.1 Grant of Rights. Except in connection with issuances (i) in an Initial Public Offering, (ii) in an Approved Sale, (iii) upon the conversion or exercise of securities convertible into or containing options or rights to acquire Capital Stock of the Company (to the extent such securities were issued in compliance with the provisions of this Section 11), (iv) to any employee, prospective employee, director or prospective director of the Company or any subsidiary of the Company as approved by the Board, (v) resulting in net proceeds to the Company of less than an aggregate of $5 million after the completion of the equity financing for the Panolam Acquisition, (vi) as consideration for the acquisition of any business entity by the Company or any of its subsidiaries by merger, amalgamation, purchase of substantially all of the assets or capital stock of such entity, or other reorganization whereby the Company owns not less than a majority of the voting power of such entity or the surviving or successor entity provided such acquisition is approved by the Board; (vii) to any bank, subordinated debt lender, equipment lessor, landlord or

other similar financial institution or investor in connection with a loan transaction or equipment lease or similar commercial transaction, provided that any such issuance is approved by the Board; and (viii) in connection with any stock split, stock dividend, distribution or recapitalization by the Company, if the Company authorizes the issuance or sale of any Capital Stock, or any securities convertible into or containing options or rights to acquire Capital Stock, to any Person, the Company shall offer to sell by written notice containing the information described in Section 11.2 to each Holder who is included in a Designated Holder Group a portion of such shares or securities equal to the quotient determined by dividing (a) the number of Shares held by such Holder by (b) the total number of Shares owned by all Holders who are included in a Designated Holder Group prior to such issuance. The purchase price for all shares and securities offered to each Holder shall be the same price per share being paid by the proposed purchaser of such shares and securities and shall be payable at the same time as the closing of the sale to such purchaser in cash by wire transfer of immediately available funds. If the Company authorizes the issuance or sale of Capital Stock for consideration that is not wholly in cash, the purchase price payable by each Holder shall be cash equal to the Equivalent Value thereof. Any Holder exercising rights hereunder who defaults in whole or in part in payment with respect to the purchase of any securities hereunder automatically and irrevocably forfeits the right to participate in any future issuances to which this Section 11.1 is applicable.

11.2 Election. In order to exercise its purchase rights hereunder, each Holder must deliver a written notice to the Company describing such Holder’s election hereunder within 10 days after receipt of written notice from the Company pursuant to Section 21.6 describing in reasonable detail the shares or securities being offered, the purchase price thereof, the payment terms and such Holder’s percentage allotment.

11.3 Expiration of Right. Upon the expiration of the offering periods described above, the Company shall be entitled to sell such shares or securities which the Holders have not elected to purchase during the 270 days following such expiration on terms and conditions no more favorable to the purchasers thereof than those offered to the Holders. Any shares or securities offered or sold by the Company to any Person after such 270-day period must be reoffered to the Holders pursuant to the terms of this Section 11.

12. Voting Agreement.

12.1 Directors. The Genstar Holders Group (so long as it is an Eligible Designated Holder Group), acting by Majority Approval of the Holders included in such Eligible Designated Holder Group, shall be entitled to designate through its Voting Representative as a nominee for election to the Board three (3) Designated Directors. The Sterling Partners Holders Group (so long as it is an Eligible Designated Holder Group), acting by Majority Approval of the Holders included in such Eligible Designated Holder Group, shall be entitled to designate through its Voting Representative as a nominee for election to the Board two (2) Designated Directors. The Sterling Parallel Holders Group (so long as it is an Eligible Designated Holder Group), acting by Majority Approval of the Holders included in such Eligible Designated Holder Group, shall be entitled to designate through its Voting Representative as a nominee for election to the Board one (1) Designated Director. Each Holder of Shares which may be voted to elect directors of the Company agrees to vote all such Shares held by such Holder (and to execute and deliver written consents in lieu thereof) in favor of and approving the election of each such designee as a director

of the Company (subject to the provisions of Sections 12.3 through 12.5). In addition, each Holder agrees to vote all such Shares held by such Holder (and to execute and deliver written consents in lieu thereof) in favor of and approving the election as a director of the Company of the Company’s Chief Executive Officer.

12.2 Death, Resignation, Removal. Each Holder of Shares which may be voted to remove directors of the Company agrees that such Holder shall not vote such Shares (or execute a written consent in lieu thereof) to remove (except for Cause) a Designated Director without the consent of the Voting Representative of the Eligible Designated Holder Group that designated such Designated Director (given pursuant to Majority Approval by the Holders included in such Eligible Designated Holder Group). Any vacancy on the Board caused by the death, resignation or removal of a Designated Director designated by an Eligible Designated Holder Group shall be filled by a successor Designated Director designated by such Eligible Designated Holder Group (acting by Majority Approval of the Holders included in such Eligible Designated Holder Group) through its Voting Representative, and each Holder of Shares which may be voted to elect directors of the Company agrees to vote all such Shares held by such Holder (and to execute and deliver written consents in lieu thereof) in favor of and approving the election of such successor designee as a director of the Company (subject to the provisions of Section 12.3 through Section 12.5).

12.3 Removal at Request and For Cause. Each Holder of Shares which may be voted to remove directors of the Company agrees to vote all Shares held by such Holder (and to execute and deliver written consents in lieu thereof) in favor of and approving the removal as a director of the Company of any Designated Director designated by the Voting Representative of an Eligible Designated Holder Group pursuant to Section 12.1 or 12.2 upon written request of such Voting Representative pursuant to Majority Approval by the Holders included in such Eligible Designated Holder Group. Any director of the Company may be removed for Cause at any time in accordance with the By-laws of the Company, and no Holder shall be required under this Agreement to vote against any such removal. If a Designated Director is removed for Cause, the provisions of Section 12.2 shall apply with respect to the designation of such removed Designated Director’s successor.

12.4 Cessation of Rights. When a Designated Holder Group ceases to be an Eligible Designated Holder Group, the Holders in such Designated Holder Group and its Voting Representative shall have no further rights hereunder to designate any director, but the Holders included in such Designated Holder Group and its Voting Representative shall continue to have all other rights and obligations hereunder and under the Registration Rights Agreement until such time as there are no Holders in such Designated Holder Group.

12.5 Procedures. The Company hereby agrees to deliver to the Voting Representatives a written notice (“Election Notice”) at least 14 days prior to (i) sending notice to the stockholders of the Company of any annual, special or other meeting of stockholders of the Company at which directors are to be elected (including the filling of any vacancy on the Board) and (ii) the delivery of any written consent to any stockholder of the Company to be utilized for the election of directors (including filling any vacancy on the Board), unless the Election Notice is waived by such Voting Representatives. The Election Notice, unless so waived, shall state the time, place and date of any such stockholders meeting and the date notice of such stockholders meeting will be sent to the stockholders of the Company (the “Meeting Notice Date”) or the first

date on which such written consent is to be delivered to any stockholder of the Company (the “Consent Delivery Date”). At least two (2) days prior to the Meeting Notice Date or the Consent Delivery Date, as the case may be, the Voting Representative for each Eligible Designated Holder Group that is entitled pursuant to Section 12.1 to designate a director to the Board to be filled at any such stockholders meeting or pursuant to such written consent shall designate in writing to the Company and the other Voting Representatives each designee of such Eligible Designated Holder Group who it its nominee to fill such position(s). If any such designation of the designee(s) of an Eligible Designated Holder Group is not so received by the Company by such time, each position on the Board to be filled by the designee of such Eligible Designated Holder Group shall remain vacant until such position is filled by a designee of such Eligible Designated Holder Group. With respect to all such designations timely received by the Company, the Company shall include in the notice of such stockholders meeting or in such written consent the name of each such designee and the name of the Eligible Designated Holder Group that designated such each Director Designee.

12.6 Agreement to Cooperate. In order to effectuate the provisions of this Section 12, each Holder of Shares which may be voted to elect or remove directors of the Company hereby agrees that when any consent or vote of the stockholders of the Company is required to be taken or made in order to effect the election of any designee of any Eligible Designated Holder Group as a director of the Company or the removal of any Designated Director pursuant to this Section 12, such Holder shall, at the request of any Voting Representative, use such Holder’s reasonable commercial efforts (including joining with other Holders) to call, or cause the Company and the appropriate officers and directors of the Company to call, a special or annual meeting of stockholders of the Company, or to deliver to the stockholders of the Company a consent in writing in lieu of any such meeting, to effect such election or removal.

12.7 Additional Directors. The Holders of the Required Two-Thirds Percentage shall designate a director to fill any vacancies and newly-created directorships (which are not reserved for Designated Directors) resulting from any increase in the authorized number of directors. Each Holder of Shares which may be voted to elect directors of the Company agrees to vote all such Shares held by such Holder (and to execute and deliver written consents in lieu thereof) in favor of and approving the election of each such designee as a director of the Company (subject to the provisions of Sections 12.3 through 12.5).

12.8 Conflicting Provisions in Governing Instruments. Each Holder of Shares which may be voted to elect directors of the Company shall vote such Shares, and shall take all reasonable actions necessary, to ensure that the Company’s Certificate of Incorporation and By-Laws do not, from time to time, conflict with the provisions of this Agreement. If the provisions of this Agreement conflict with the Company’s Certificate of Incorporation or Bylaws, each such Holder agrees that the provisions of this Agreement shall control. If such conflict occurs, each such Holder shall vote, and shall use its best reasonable efforts to cause its Designated Director, if any, to vote, and each such Holder and the Company shall take all reasonable actions necessary, to amend the provisions of the Company’s Certificate of Incorporation or Bylaws that conflict with this Agreement to eliminate such conflict.

13. Size of Board; Committees.

13.1 Number of Directors. The number of directors on the Board as of the Effective Date shall be seven (7). The size of the Board may not be increased above ten (10) or decreased below seven (7) without the written approval of the Voting Representative for each Eligible Designated Holder Group (acting as directed by Majority Approval of the Holders included in such Eligible Designated Holder Group). The Holders shall vote their Shares in favor of any change in the authorized number of directors as may be approved in writing by the Voting Representative for each Eligible Designated Holder Group (acting as directed by Majority Approval of the Holders included in such Eligible Designated Holder Group).

13.2 Board Committees. Each committee of the Board shall include at least one (1) Designated Director of each Eligible Designated Holder Group.

14. Affiliated Transactions. Each Holder agrees that, without the prior written approval of the Holders of at least 75% of the Common Shares outstanding and subject to this Agreement held by all Holders other than such Holder and its Related Persons, such Holder shall not, and shall not permit any of its Related Persons to, enter into, renew, extend or be a party to any transaction or series of transactions (including the purchase, sale, lease or exchange of any property or the rendering of any service) with the Company or any of its subsidiaries except for (i) issuance of Capital Stock pursuant to, or the funding of, employment arrangements, stock options and stock ownership plans approved by the Board, (ii) the grant of share options or similar rights to employees and directors pursuant to plans approved by the Board, (iii) loans or advances to executive officers approved by the Board, (iv) the payment of reasonable fees to directors of the Company and its subsidiaries who are not employees of the Company or its subsidiaries in their capacities as Board members or members of committees of the Board (in the same amounts and on the same terms as to all such directors serving in such capacities) as may be approved by the Board, (v) any transaction between subsidiaries of the Company, and (vi) transactions pursuant to this Agreement, the Registration Rights Agreement and the Engagement Letter and any amendments thereto made in accordance with the provisions thereof and this Agreement and any transactions permitted thereby.

15. Rights to Participate in Management; Information. The Company agrees to permit any authorized representatives designated by any Holder at its expense to visit and inspect any of the properties of the Company and its subsidiaries and to inspect, copy and take extracts from its and their books and records, including its and their financial and accounting records and other data (including properties), and to consult and discuss with its and their officers regarding its and their affairs, finances accounts and significant business issues, including operating plans, all upon reasonable notice and at such reasonable times during normal business hours and as often as may reasonably be requested. In addition, during any period of time that the Genstar Holders Group, the Sterling Partners Holders Group or the Sterling Parallel Holders Group is not included in an Eligible Designated Holder Group but continues to own shares of Capital Stock, the Company shall send to a Person designated by each of the Genstar Holders Group, the Sterling Partners Holders Group or the Sterling Parallel Holders Group copies of all materials sent by the Company to its board of directors and such Holder shall have the right to designate and send a representative to attend all meetings of the Company’s board of directors and participate in discussions, if desired, in a nonvoting observer capacity. The foregoing rights are

subject to any customary confidentiality requirements. Subject to the receipt of a customary confidentiality agreement from any Holder then holding at least ten percent (10%) of the Shares subject to this Agreement held by such Holder on the Effective Date, the Company shall deliver to such Holder, at such Holder’s request, all historical financial statements of the Company (i) distributed by the Company to members of the board of directors of the Company, at or about the time delivered to such Board members, and (ii) provided by the Company pursuant to the requirements of any senior secured loan agreement or indenture to which the Company or any of its subsidiaries is a party, at or about the time delivered to the Persons entitled thereto under any such agreement or indenture.

16. Covenants of the Company. The Company covenants and agrees that, so long as any Holder is included in a Designated Holder Group, the Company shall comply with the covenants set forth in this Section 16.

Each Holder severally represents and warrants to the Company and the other Holders that such Holder has the sole right and power to vote and dispose of the Shares held in its name, except as contemplated by this Agreement. Such Holder agrees not to enter into any voting arrangement or understanding, whether by proxy, voting agreement or otherwise, with respect to such Shares, other than this Agreement.

18. Endorsement of Share Certificates. All certificates of Shares of the Company now owned or that may hereafter be acquired by the Holders or any transferee shall be endorsed on the reverse side thereof substantially as follows:

BY THE TERMS OF A STOCKHOLDERS AGREEMENT, CERTAIN RESTRICTIONS HAVE BEEN PLACED UPON THE TRANSFER AND VOTING OF THE SHARES REPRESENTED BY THIS CERTIFICATE. THE COMPANY WILL FURNISH A COPY OF SUCH AGREEMENT TO THE RECORD HOLDER OF THIS CERTIFICATE WITHOUT CHARGE UPON WRITTEN REQUEST TO THE COMPANY AT ITS PRINCIPAL PLACE OF BUSINESS OR REGISTERED OFFICE. NO REGISTRATION OR TRANSFER OF ANY SHARES REPRESENTED BY THIS CERTIFICATE WILL BE MADE ON THE BOOKS OF THE COMPANY UNLESS AND UNTIL SUCH RESTRICTIONS HAVE BEEN COMPLIED WITH.

THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY OTHER FEDERAL OR STATE SECURITIES LAW (COLLECTIVELY, THE “SECURITIES LAWS”) AND MAY NOT BE OFFERED, SOLD, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF UNLESS MADE PURSUANT TO A REGISTRATION STATEMENT UNDER THE SECURITIES LAWS OR PURSUANT TO ANY AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS THEREOF. FURTHER, THE SHARES HAVE BEEN ACQUIRED FOR INVESTMENT AND MAY NOT BE OFFERED, SOLD, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF UNLESS AND UNTIL (1) SUCH SHARES HAVE BEEN REGISTERED UNDER THE SECURITIES LAWS, (2) SUCH SHARES ARE DISPOSED OF PURSUANT TO RULE 144 UNDER THE SECURITIES ACT, OR (3) THE HOLDER OF SUCH SHARES PROVIDES PANOLAM HOLDINGS CO. WITH (A) AN UNQUALIFIED WRITTEN OPINION OF LEGAL COUNSEL, WHICH COUNSEL AND OPINION (IN FORM AND SUBSTANCE) SHALL BE REASONABLY SATISFACTORY TO THE COMPANY, TO THE EFFECT THAT THE PROPOSED DISPOSITION OF SUCH SHARES MAY BE EFFECTED WITHOUT REGISTRATION UNDER THE SECURITIES LAWS OR (B) SUCH OTHER EVIDENCE AS MAY BE REASONABLY SATISFACTORY TO THE COMPANY THAT THE PROPOSED DISPOSITION OF SUCH SHARES MAY BE EFFECTED WITHOUT REGISTRATION UNDER THE SECURITIES LAWS.

The Company also shall place stop transfer instructions with respect to such Shares in the securities register for such purpose.

19. Breach. Any Disposition or attempted Disposition in breach of this Agreement shall be void and of no effect. Notwithstanding the foregoing, the Company may treat any such voided Disposition as an Offer pursuant to Section 3.4. In such event, the date of the Offer shall be deemed to be the date that the Company, after its receipt of evidence satisfactory to it that such voided Disposition has occurred, gives written notice of such voided Disposition to the Eligible Offerees. In connection with any such voided Disposition, the Company may hold and refuse to transfer any Shares or certificate therefor tendered for transfer, in addition and without prejudice to any and all other rights and remedies which may be available to the Company and the Holders.

20. Termination. This Agreement shall terminate automatically upon the earliest to occur of (i) the dissolution of the Company, (ii) the occurrence of any event which reduces the number of Holders to one (1) in accordance with the terms hereof, (iii) the completion of an Initial Public Offering, and (iv) the written approval of the Holders of 90% of the Shares subject to this Agreement; provided, however, that the provisions of Section 8 shall survive such termination to the extent and for the periods set forth therein; and provided, further, that the provisions of Section 5 shall not terminate until such time as Genstar Capital Partners IV, L.P., Sterling Group Partners II, L.P. and Sterling Group Partners II (Parallel), L.P. cease to own any shares of Capital Stock. The Voting Representative of each Designated Holder Group shall be exclusively authorized to act on behalf of and as directed by each Holder included in such Voting Representative’s Designated Holder Group with respect to the giving or withholding of such approval.

20.1 Voting Representatives. No Voting Representative shall have any liability to any Holder relating to such Voting Representative’s acts or omissions in such capacity, except for liabilities found by a final judgment of a court of competent jurisdiction (not subject to further appeal) to have resulted solely from the willful misconduct of such Voting Representative. By Majority Approval of the Holders included in a Designated Holder Group, the Voting Representative of such Designated Holder Group may be removed and replaced by a successor Voting Representative; provided however, that no change in a Voting Representative shall be effective as against the Company or any Holder or other Voting Representative until the Company and all other Voting Representatives have received written notice thereof, including the name of the successor Voting Representative and its address for purpose of notice under Section 21.6. The Company shall not be responsible for any expenses incurred by any Voting Representative or any Holder included in a Designated Holder Group in connection with the solicitation of any vote, consent or approval by Holders included in a Designated Holder Group.

21. Miscellaneous Provisions.

21.1 Ultimate Disposition. If a Holder disposes of all of such Holder’s Shares in accordance with this Agreement, such Holder shall cease to be a party to this Agreement or be deemed to be a “Holder” for purposes hereof, and shall have no further rights or obligations hereunder other than liability for any breach of this Agreement occurring prior to the time such Holder ceases to be a party.

21.2 Spouses. The spouses of the individual Holders, by their execution of this Agreement or an Adoption Agreement, (i) evidence that they are fully aware of, understand and fully consent and agree to the provisions of this Agreement and its binding effect upon any community property or similar marital property interests in the Shares that they may now or hereafter own, and (ii) agree that the termination of their marital relationship with any individual Holder for any reason shall not have the effect of removing any Shares otherwise subject to this Agreement from the coverage hereof. Each individual Holder shall cause his or her spouse (and any subsequent spouse) to execute and deliver, within 30 days after the request of the Company, a counterpart of this Agreement or an Adoption Agreement.

21.3 Appointment of Company. Each Holder and such Holder’s spouse, if any, to the extent permitted by law, (i) appoint the Company as their agent and attorney-in-fact to make the Offers and take all actions required under Sections 3.1 through 3.4 and 9 and to execute any required Adoption Agreement on their behalf, and (ii) expressly bind themselves to such Offers and the Company’s execution of any such Adoption Agreement without further action on their part. To the extent permitted by law, such powers-of-attorney granted herein are deemed to be coupled with an interest in the Shares and shall survive the death, disability, bankruptcy or dissolution of such Holder or such Holder’s spouse, if any.

21.4 Changes in Shares. If there is any change in the Shares by way of stock split, reverse stock split, stock dividend, reclassification, merger, amalgamation, consolidation, reorganization, recapitalization, or any other means, then all appropriate adjustments to the provisions hereof shall be made so that the rights and obligations of the parties hereto under this Agreement shall continue with respect to the Shares as so changed.

21.5 Pledged Shares. If any Shares are pledged to a bank or other financial institution (it being recognized that any such pledge constitutes a Disposition pursuant hereto and may be made only upon compliance with this Agreement), and such Shares are to be sold to Eligible Offeree(s), then the Holders and their spouses (if the transferor of such Shares) authorize (i) such bank or other financial institution to deliver certificates representing such shares to the Company against receipt of the Purchase Price therefor, (ii) the Eligible Offeree(s) to make payment of the Purchase Price to such bank or other financial institution for application to any debt secured by any such Shares, and (iii) such bank or other financial institution to apply such Purchase Price so received to any such debt.

21.6 Notices and Other Communications.

21.8 Amendments and Waivers. No alteration, modification, amendment, change or waiver of any provision of this Agreement shall be effective or binding on any party hereto unless the same is in writing and is executed by the Company and the Holders of the Required Two-Thirds Percentage at the time thereof; provided, however, that (i) in no event shall any amendment adversely affect a Holder’s rights and obligations hereunder in a manner different from any other Holder without such Holder’s prior written consent; (ii) in no event shall any amendment adversely affect the rights and obligations hereunder of the Holders within a particular Designated Holder Group in a manner different from the Holders within any other Designated Holder Group without each such Holder’s prior written consent; (iii) in no event shall Section 3.1, Section 4 (as it relates to Section 3.1), Section 6, Section 9, Section 11, Section 20 or this Section 21.8 be altered, modified, amended, changed or waived without the prior written consent of the Holders of 90% of the Shares subject to this Agreement; (it being agreed that the Voting Representative of each Designated Holder Group shall be exclusively authorized to act on behalf of and as directed by each Holder included in such Voting Representative’s Designated Holder Group with respect to the giving or withholding of such consent); and (iv) the Company may amend this Agreement without the consent of any Holder to cure any ambiguity or to cure, correct or supplement any defective provision contained herein, provided that such action shall not affect adversely the interests of any Holder.

21.9 Modification and Severability. If a court of competent jurisdiction declares that any provision of this Agreement is illegal, invalid or unenforceable, then such provision shall be modified automatically to the extent necessary to make such provision fully legal, valid or enforceable. If such court does not modify any such provision as contemplated herein, but instead declares it to be wholly illegal, invalid or unenforceable, then such provision shall be severed from this Agreement, this Agreement and the rights and obligations of the parties hereto shall be construed as if this Agreement did not contain such severed provision, and this Agreement otherwise shall remain in full force and effect.

21.10 Enforceability. This Agreement shall be enforceable by and against the Company, the Holders and their respective spouses, guardians, heirs, legatees, executors, legal representatives, administrators, and permitted successors and assignees.

21.11 No Third-Party Beneficiaries. No Person not a party to this Agreement shall have any rights under this Agreement as a third-party beneficiary or otherwise; provided, however, that the Voting Representatives may rely upon and shall be entitled to the benefits of this Agreement.

Notwithstanding any provision hereof, none of the obligations of any Holder that is an entity or any of their respective Affiliates that is an entity under this Agreement shall be an obligation of any officer, director, member, limited partner or general partner of any of the foregoing entities. Any liability or obligation of any Holder that is an entity arising out of this Agreement shall be limited to and satisfied only out of the assets of such Holder.

21.18 Certain Representations. Each Holder severally represents and warrants to the Company that:

(i) The acquisition of the Common Shares by such Holder is for such Holder’s own account, is for investment purposes, and is not with a view to, or for offer or sale for the Company in connection with, the distribution of any Common Shares in violation of the Securities Act or any state securities laws (collectively, the “Securities

Laws”). Such Holder is not participating and does not have a participation in any such distribution or the underwriting of any such distribution.

(ii) Such Holder has no present intention of selling or otherwise disposing of any Common Shares in violation of the Securities Laws.

(iii) Such Holder is aware that no federal or state governmental authority has neither made any finding or determination as to the fairness of an investment in the Common Shares nor any recommendation or endorsement with respect thereto.

(iv) Such Holder has had an opportunity to ask questions of the directors and officers of the Company and the management of Panolam related to Panolam’s business, and has received answers satisfactory to it concerning the Common Shares, the Company, and Panolam and has had access to such information regarding the Common Shares, the Company and Panolam as such Holder has deemed necessary in order to make an informed investment decision regarding its investment in the Common Shares.

(v) Such Holder acknowledges that such Holder must bear the economic risk of its investment in the Company for an indefinite period of time, because the Common Shares have not been registered under the Securities Laws and, therefore, the Common Shares purchased may not be subsequently offered, sold, transferred, pledged or otherwise disposed of unless and until they have been registered under the Securities Laws or exemptions from registration thereunder are available; and such Holder further understands that only the Company can take action to register the Common Shares.

(vi) Such Holder has been advised that the Company does not expect that Rule 144 under the Securities Act will be available to the Holder for resale of the Common Shares, and that the Company will not be obligated (a) to make the filings and reports or to make available publicly the information that would be required by Rule 144 or (b) to have a public market available to enable sales to be made in “brokers transactions” thereunder, it being understood that the actions in both clauses (a) and (b) are required to permit sales under Rule 144.

(vii) In addition to compliance with the restrictions on resale under applicable Securities Laws to which the Common Shares may be subject, within a prescribed time period following a purchase of the Common Shares the Company may be required to file with the applicable securities regulatory authorities a report with respect to the purchase along with the applicable fee, which report will list, among other things, the name and residence of the purchaser as well as details concerning the purchase.

(viii) The Company will place stop transfer instructions with respect to the Common Shares purchased in the Company’s share transfer records to provide notice of the restrictions on the resale or distribution thereof imposed by the Securities Laws and this Agreement.

(ix) The legends and stop transfer instructions described herein will be placed on any new certificates or other documents issued upon presentment by such Holder of certificates or other documents for transfer.

(x) Such Holder has all power and authority, to execute, deliver and perform its obligations under this Agreement.

(xi) Such Holder is an “accredited investor” as such term is defined in Regulation D under the Securities Act.

(xii) Such Holder is not a “holding company”, a “subsidiary company” or an “affiliate” of a “holding company”, or an “affiliate of a “subsidiary company” of a “holding company”, in each case as such terms are defined in the Public Utility Holding Company Act of 1935, as amended.

21.19 Termination of Merger Agreement. Except for this Section 21.19 which shall be effective as of the date hereof, this Agreement shall be effective on the Effective Date. If the Merger Agreement is terminated prior to the closing of the transactions contemplated thereby, this Agreement shall terminate and be of no further force or effect.

This Agreement is executed by the Company, by each Holder, and by the spouse (if any) of each Holder to be effective as of the Effective Date.

EXHIBIT “A”
ADOPTION AGREEMENT (form)

This Adoption Agreement (“Adoption”) is executed pursuant to the terms of Panolam Holdings Co. Stockholders Agreement effective as of September 30, 2005, a copy of which is attached hereto and is incorporated herein by reference (the “Stockholders Agreement”), by the undersigned (“New Holder”) executing this Adoption. By the execution of this Adoption, New Holder agrees as follows:

1. Acknowledgment. New Holder acknowledges that (i) New Holder is acquiring the Shares of Panolam Holdings Co., a Delaware corporation (the “Company”) described on Attachment I (the “Shares”) subject to the terms and conditions of the Stockholders Agreement and (ii) upon execution and delivery of this Adoption, New Holder shall be deemed a “Holder” under the Stockholders Agreement and shall have all of the rights and obligations of a “Holder” under the Stockholders Agreement.

2. Agreement. New Holder (i) agrees that the Shares acquired by New Holder shall be bound by and subject to the terms of the Stockholders Agreement, and (ii) hereby adopts the Stockholders Agreement with the same force and effect as if New Holder were originally a party thereto.

3. Notice. Any notice required or permitted by the Stockholders Agreement shall be given to New Holder at the address listed beside New Holder’s signature below.

4. Joinder. The spouse of the undersigned New Holder, if applicable, executes this Adoption to acknowledge its fairness and that it is in such spouse’s best interests and to bind such spouse’s community interest, if any, in any shares of the capital stock of the Company, to the terms of the Stockholders Agreement.

[To be included if New Holder is acquiring the Shares pursuant to Sections 6.4 of the Stockholders Agreement or is required under Section 7 of the Stockholders Agreement]

5. Voting. New Holder hereby agrees to grant to [insert name of the transferor] and his, her or its successors and assigns, with full power of substitution (the “Designated Proxy”) upon demand, one (1) or more proxies to vote all of New Holder’s Shares, and that the Designated Proxy may demand and exercise such proxies at any time to vote all of such Shares.
