Any endorsement of a Global Units to reflect the amount of any increase or decrease in the amount of outstanding Units represented thereby shall be made by the Unit Agent and the Depositary in accordance with instructions given by the Holder thereof.

SECTION 3. Execution of Unit Certificates. Unit Certificates shall be signed on behalf of the Company by its Chairman of the Board, President, Chief Executive Officer, a Vice President, Treasurer, an Assistant Treasurer or Chief Financial Officer and by a Vice President, its Secretary or an Assistant Secretary. Each such signature upon the Unit Certificates may be in the form of a facsimile signature of any such present or future officer and may be imprinted or otherwise reproduced on the Unit Certificates.

In case any officer of the Company who shall have signed any of the Unit Certificates shall cease to be such officer before the Unit Certificates so signed shall have been countersigned by the Unit Agent, or disposed of by the Company, such Unit Certificates nevertheless may be countersigned and delivered or disposed of as though such person had not ceased to be such officer of the Company; and any Unit Certificate may be signed on behalf of the Company by any person who, at the actual date of the execution of such Unit Certificate, shall be a proper officer of the Company to sign such Unit Certificate, although at the date of the execution of this Unit Agreement any such person was not such officer.

Unit Certificates shall be dated the date of countersignature by the Unit Agent.

SECTION 4. Registration and Countersignature. The Units shall be numbered and shall be registered on the books of the Company maintained at the principal office of the Unit Agent in Canton, Massachusetts (the “Unit Register”) as they are issued.

Unit Certificates shall be, either manually or facsimile signature, countersigned by the Unit Agent and shall not be valid for any purpose unless so countersigned. The Unit Agent shall, upon written instructions of the Chairman of the Board, the President, Chief Executive Officer, a Vice President, the Treasurer, an Assistant Treasurer, Chief Financial Officer, Secretary or an Assistant Secretary of the Company, initially countersign and deliver Units and shall thereafter countersign and deliver Units as otherwise provided in this Agreement.

The Company and the Unit Agent may deem and treat the registered holders (the “Holders” or “Unitholders”) of the Unit Certificates as the absolute owners thereof (notwithstanding any notation of ownership or other writing thereon made by anyone) for all purposes, and neither the Company nor the Unit Agent shall be affected by any notice to the contrary.

SECTION 5. Transfer and Exchange of Units. The Unit Agent shall from time to time, subject to the limitations of Section 6, register the transfer of any outstanding Units upon the records to be maintained by it for that purpose, upon surrender thereof duly endorsed or accompanied (if so required by it) by a written instrument or instruments of transfer in form satisfactory to the Unit Agent, and bearing a medallion signature guarantee by a guarantor institution approved by the Securities Transfer Association, duly executed by the registered Holder or Holders thereof or by the duly appointed legal representative thereof or by a duly authorized attorney. Any Holder desiring to exchange a Unit Certificate or Certificates shall

make such request in writing delivered to the Unit Agent, and shall surrender, duly endorsed or accompanied (if so required by the Unit Agent) by a written instrument or instruments of transfer in form satisfactory to the Unit Agent, and bearing a medallion signature guarantee by a guarantor institution approved by the Securities Transfer Association, the Unit Certificate or Certificates to be so exchanged.

Upon registration of transfer, the Company shall execute and the Unit Agent shall countersign and deliver by certified mail a new Unit Certificate or Certificates to the persons entitled thereto. The Unit Certificates may be exchanged at the option of the Holder thereof, when surrendered at the office or agency of the Company maintained for such purpose, which initially will be the principal office of the Unit Agent in Canton, Massachusetts for another Unit Certificate, or other Unit Certificates of different denominations and of like tenor.

No service charge shall be made for any exchange or registration of transfer of Unit Certificates, but the Company may require payment of a sum sufficient to cover any stamp or other tax or other governmental charge that is imposed in connection with any such exchange or registration of transfer.

SECTION 6. Registration of Transfers and Exchanges.

(a) Transfer and Exchange of Units. When Units are presented to the Unit Agent with a request meeting those requirements set forth in Section 5, when required, above:

(i) to register the transfer of the Unit; or

(ii) to exchange such Unit for an equal number of Units of other authorized denominations,

the Unit Agent shall register the transfer or make the exchange as requested if (and may refuse to register any transfer or exchange unless) the requirements under this Agreement as set forth in this Section 6 for such transactions are met; provided, however, that the Unit presented or surrendered for registration of transfer or exchange:

(x)

shall be duly endorsed or accompanied by a written instruction of transfer in form satisfactory to the Company and the Unit Agent, duly executed by the Holder thereof or by his or her representative, duly authorized in writing, and affixed with a signature guarantee from a guarantor participating in a medallion signature guarantee program approved by the Securities Transfer Association; and

A Certificated Unit may not be exchanged (including in connection with any transfer of a Unit) by a Holder for a beneficial interest in a Global Unit except upon receipt by the Unit Agent of an opinion of counsel if the Unit is affixed with a restrictive legend and satisfaction of the requirements set forth below. Upon receipt by the Unit Agent of a Certificated Unit, duly endorsed or accompanied by appropriate instruments of transfer, in form satisfactory to the Unit Agent, together with:

(i) unless the Private Placement Legend has been removed from the certificate evidencing the Units, certification from such Holder (in substantially the form of Exhibit C hereto) that such Holder is a QIB or that such Certificated Unit is being transferred to a QIB in accordance with Rule 144A under the Securities Act; and

(ii) written instructions directing the Unit Agent to make, or to direct the Depositary to make, an endorsement on the Global Unit to reflect an increase in the aggregate amount of the Units represented by the Global Unit,

then the Unit Agent shall cancel such Certificated Unit and cause, or direct the Depositary to cause, in accordance with the standing instructions and procedures existing between the Depositary and the Unit Agent the number of Units represented by the Global Unit to be increased accordingly. If no Global Unit is then outstanding, the Company shall issue and the Unit Agent shall upon written instructions from the Company authenticate a new Global Unit in the appropriate amount.

(c) Transfer or Exchange of Beneficial Interests in Global Units. The transfer or exchange of beneficial interests in Global Units shall be effected through the Depositary, in accordance with this Section 6, the Private Placement Legend, the other provisions of this Agreement (including the restrictions on transfer set forth herein) and the procedures of the Depositary therefor.

(d) Transfer or Exchange of a Beneficial Interest in a Global Unit for a Certificated Unit.

(D)

if such beneficial interest is being transferred in reliance on Regulation S under the Securities Act, delivery of (i) a certification to that effect (in substantially the form of Exhibit C hereto) and (ii) a Transferee Letter of Representation in connection with Transfers pursuant to Regulation S in the form of Exhibit E hereto; or

In connection with any such transfer or exchange, the Unit Agent will cause, in accordance with the standing instructions and procedures existing between the Depositary and the Unit Agent, the aggregate amount of the Global Unit to be reduced accordingly and, following such reduction, the Company will execute and, upon receipt of a countersignature order in the form of an Officers’ Certificate, the Unit Agent will countersign and deliver to the transferee a Certificated Unit.

(ii) Certificated Units issued in exchange for or in connection with a transfer of a beneficial interest in a Global Unit pursuant to this Section 6 shall be registered in such names and in such authorized denominations as the Depositary, pursuant to instructions from its Direct or Indirect Participants or otherwise, shall instruct the Unit Agent in writing.

(ii) the Depositary for the Global Units notifies the Company that it has ceased to be a clearing agency registered under the Securities Act of 1934, as amended,

then the Company will execute, and the Unit Agent will, upon receipt of an Officers’ Certificate requesting the countersignature and delivery of Certificated Units, countersign and deliver, Certificated Units in an aggregate number equal to the aggregate number of Units represented by the Global Unit in exchange for such Global Unit.

(g) Cancellation or Adjustment of a Global Unit. At such time as all beneficial interests in a Global Unit have either been exchanged for Certificated Units, redeemed, repurchased or canceled, such Global Unit shall be returned to the Company or, upon written order to the Unit Agent in the form of an Officers’ Certificate from the Company, retained and canceled by the Unit Agent. At any time prior to such cancellation, if any beneficial interest in a Global Unit is exchanged for Certificated Units, redeemed, repurchased or canceled, the number of Units represented by such Global Units shall be reduced accordingly and an endorsement shall be made on such Global Unit by the Unit Agent to reflect such reduction.

(h) Legends.

(i) Private Placement Legend. Except as provided below, each Unit Certificate evidencing the Units (and all Units issued in exchange therefor or substitution thereof) shall bear a legend substantially to the effect set forth in Exhibit A (the “Private Placement Legend”). Upon any sale or transfer of a Unit pursuant to Rule 144 under the Securities Act in accordance with this Section 6 or under an effective registration statement under the Securities Act, the Unit Agent shall permit the Holder of a Unit to exchange such Unit for a Unit that does not bear the Private Placement Legend, provided that, in the case of a sale or transfer pursuant to Rule 144 under the Securities Act, an opinion of the Company or of counsel to the Company is tendered therewith indicating that there are no impediments to the removal of such Private Placement Legend under the applicable federal securities laws of the United States.

(i) Obligations with Respect to Transfers and Exchanges of Certificated Units and Global Units.

(i) To permit registrations of transfers and exchanges, the Company shall execute, at the Unit Agent’s request, and the Unit Agent shall authenticate Certificated Units and Global Units.

(ii) All Certificated Units and Global Units issued upon any registration, transfer or exchange of Certificated Units and Global Units shall be the valid obligations of the Company, entitled to the same benefits under this Agreement as the Certificated Units and Global Units surrendered upon the registration of transfer or exchange.

(iii) Prior to due presentment for registration of transfer of any Unit, the Unit Agent and the Company may deem and treat the Person in whose name any Unit is registered as the absolute owner of such Unit, and neither the Unit Agent nor the Company shall be affected by notice to the contrary.

SECTION 7. Rule 144A. The Company covenants that it will file the reports required to be filed by it under the Securities Act and the Exchange Act and the rules and regulations adopted by the SEC thereunder in a timely manner (including any extensions permitted by Rule 12b-25 of the Exchange Act (or any successor rule or regulation)) in accordance with the requirements of the Securities Act and the Exchange Act and, if at any time the Company is not required to file such reports, it will, upon the request of any Holder or beneficial owner of Units, make available such information necessary to permit sales pursuant to Rule 144A under the Securities Act.

SECTION 8. Mutilated or Missing Unit Certificates. In case any of the Unit Certificates shall be mutilated, lost, stolen or destroyed, the Company may at its discretion issue and the Unit Agent may countersign, in exchange and substitution for and upon cancellation of the mutilated Unit Certificate, or in lieu of and substitution for the Unit Certificate lost, stolen or destroyed, a new Unit Certificate of like tenor and representing an equivalent number of Units, but only upon receipt of evidence satisfactory to the Company and the Unit Agent of

such loss, theft or destruction of such Unit Certificate and indemnity also satisfactory to them, which indemnity shall include a corporate bond of indemnity satisfactory in form and substance to the Company and the Unit Agent.

SECTION 10. Supplements and Amendments. (a) From time to time, the Company and the Unit Agent, without the consent of the Holders of the Units, may amend or supplement this Agreement, (1) to evidence the succession of another Person to the Company and the assumption by any such successor of the covenants of the Company in the Unit Agreement; (2) to add to the covenants of the Company for the benefit of the Holders of Units, or to surrender any right or power herein conferred upon the Company; (3) to provide for uncertificated Units in addition to or in place of the certificated Units; (4) to evidence and provide for the acceptance of the appointment under the Unit Agreement of a successor Unit Agent; (5) to provide for or confirm the issuance of Additional Units in accordance with the terms of the Unit Agreement; (6) to cure any ambiguity, defect, omission, mistake or inconsistencies or making any change that does not adversely affect, in any material respect, the legal rights of Holders of Units; (7) to make any other provisions with respect to matters or questions arising under the Unit Agreement, provided that such actions pursuant to this clause

SECTION 11. Concerning the Unit Agent. The Unit Agent undertakes the duties and obligations expressly imposed by this Agreement (and no implied duties) upon the following terms and conditions, by all of which the Company and the Holders, by their acceptance of Units, shall be bound:

(a) The Unit Agent assumes no responsibility for the correctness of any statement contained herein or in the Unit Certificate, except such as describe the Unit Agent or any action taken by it.

(b) The Unit Agent shall be protected and shall not be responsible for and shall incur no liability to the Company or any Holder for any failure of the Company to comply with the covenants contained in this Agreement or in the Units to be complied with by the Company.

(c) The Unit Agent may execute and exercise any of the rights or powers hereby vested in it or perform any duty hereunder either itself (through its employees) or by or through its attorneys or agents (which shall not include its employees) and shall not be responsible for the misconduct of any attorney or agent appointed by it without bad faith, gross negligence or willful misconduct.

(d) The Unit Agent may consult at any time with legal counsel satisfactory to it (who may be counsel for the Company or an employee of the Unit Agent), and the Unit Agent shall incur no liability or responsibility to the Company or to any Holder in respect of any action taken, suffered or omitted by it hereunder in accordance with the opinion or the advice of such counsel.

(e) Whenever in the performance of its duties under this Agreement the Unit Agent shall deem it necessary or desirable that any fact or matter be proved or established by the Company prior to taking or suffering any action hereunder, such fact or matter (unless such evidence in respect thereof be herein specifically prescribed) may be deemed conclusively to be proved and established by a certificate signed by the Chairman of the Board, the President, one of the Vice Presidents, the Treasurer or the Secretary of the Company and delivered to the Unit Agent; and such certificate shall be full authorization to the Unit Agent for any action taken or suffered by it under the provisions of this Agreement in reliance upon such certificate.

(f) The Company agrees to pay the Unit Agent such compensation for all services rendered by the Unit Agent in the performance of its duties under this Agreement as may be separately agreed in writing, to reimburse the Unit Agent for all expenses, taxes and governmental charges and other charges of any kind and nature incurred by the Unit Agent in the performance of its duties under this Agreement (including, without limitation, reasonable fees and expenses of counsel), and to indemnify the Unit Agent and its agents, employees, directors, officers and affiliates and save it and them harmless against any and all liabilities, losses and expenses, including, without limitation, judgments, costs and counsel fees, for anything done or omitted by the Unit Agent in the acceptance and performance of its duties under this Agreement, except as a result of the Unit Agent’s bad faith, gross negligence or willful misconduct, including, without limitation, the costs and expenses of defending against any claim (whether asserted by the Company, a Holder or any other Person) of liability in the premises including reasonable attorneys’ fees and expenses. The provisions of this paragraph shall survive the resignation or removal of the Unit Agent and the termination of this Agreement.

(g) The Unit Agent shall be under no obligation to institute any action, suit or legal proceeding or to take any other action likely to involve expense unless the Company or one or more Holders shall furnish the Unit Agent with reasonable security and indemnity for any costs and expenses which may be incurred, but this provision shall not affect the power of the Unit Agent to take such action as the Unit Agent may consider proper, whether with or without any such security or indemnity. All rights of action under this Agreement or under any of the Units may be enforced by the Unit Agent without the possession of any of the Units or the production thereof at any trial or other proceeding relative thereto, and any such action, suit or proceeding instituted by the Unit Agent shall be brought in its name as Unit Agent, and any recovery of judgment shall be for the ratable benefit of the Holders, as their respective rights or interests may appear.

(h) The Unit Agent and any stockholder, director, officer or employee (“Related Parties”) of the Unit Agent may buy, sell or deal in any of the Units or other securities of the Company or become pecuniarily interested in any transactions in which the Company may be interested, or contract with or lend money to the Company or otherwise act as fully and freely as though it were not Unit Agent under this Agreement or such director, officer or employee. Nothing herein shall preclude the Unit Agent or any Related Party from acting in any other capacity for the Company or for any other legal entity including, without limitation, acting as Transfer Agent to the Company or an affiliate thereof.

(i) The Unit Agent shall act hereunder solely as agent, and its duties shall be determined solely by the provisions thereof. The Unit Agent shall not be liable for anything which it may do or refrain from doing in connection with this Agreement except for its own bad faith, gross negligence or willful misconduct. No implied duties or obligations shall be read into this Agreement against the Unit Agent.

(j) The Unit Agent will be protected and will not incur any liability or responsibility to the Company or to any Holder for any action taken, suffered or omitted by it in reliance on any notice, resolution, waiver, consent, order, certificate, or other paper, document or instrument reasonably believed by it to be genuine and to have been signed, sent or presented by the proper party or parties.

(k) The Unit Agent is hereby authorized to request, and directed to accept, instructions with respect to the performance of its duties hereunder from the Chairman of the Board, the President, Chief Financial Officer, Treasurer, any Vice President or the Secretary of the Company, and to apply to such officers for advice or instructions in connection with its duties, and shall not be liable for any action taken or suffered to be taken by it without bad faith, gross negligence or willful misconduct in accordance with instructions of any such officer or officers.

(l) By countersigning Unit Certificates or by any other act hereunder the Unit Agent shall not be deemed to make any representations as to validity or authorization of the Units or the Unit Certificates (except as to its countersignature thereon) or the correctness of the representations of the Company made in any certifications that the Unit Agent receives.

(m) No provision of this Agreement shall require the Unit Agent to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder or in the exercise of its rights if there shall be reasonable grounds for believing that repayment of such funds or adequate indemnification against such risk or liability is not reasonably assured to it.

SECTION 12. Change of Unit Agent. The Unit Agent may resign and be discharged from its duties under this Agreement by giving to the Company 30 days’ notice in writing. The Unit Agent may be removed by like notice to the Unit Agent from the Company. If the Unit Agent shall resign or be removed or shall otherwise become incapable of acting, the Company shall appoint a successor to the Unit Agent. If the Company shall fail to make such appointment within a period of 30 days after such removal or after it has been notified in writing of such resignation or incapacity by the resigning or incapacitated Unit Agent or by any

Holder (who shall with such notice submit his Unit for inspection by the Company), then any Holder or the removed, resigning or incapacitated Unit Agent may apply to any court of competent jurisdiction for the appointment of a successor to the Unit Agent. Pending appointment of a successor to the Unit Agent, either by the Company or by such court, the duties of the Unit Agent shall be carried out by the Company. Any successor unit agent, whether appointed by the Company or such a court, shall be a bank or trust company in good standing, incorporated under the laws of the United States of America or any State thereof or the District of Columbia and having at the time of its appointment as unit agent a combined capital and surplus of at least $50,000,000. After appointment, the successor unit agent shall be vested with the same powers, rights, duties and responsibilities as if it had been originally named as Unit Agent without further act or deed; but the former Unit Agent shall deliver and transfer to the successor unit agent any property at the time held by it hereunder, and execute and deliver any further assurance, conveyance, act or deed necessary for such purpose. Failure to file any notice provided for in this Section 12, however, or any defect therein, shall not affect the legality or validity of the resignation or removal of the Unit Agent or the appointment of the successor unit agent, as the case may be. In the event of such resignation or removal, the Company or the successor unit agent shall mail by first class mail, postage prepaid, to each Holder, written notice of such removal or resignation and the name and address of such successor unit agent.

SECTION 13. Successors. All the covenants and provisions of this Agreement by or for the benefit of the Company, the Unit Agent or any Holder of Units shall bind and inure to the benefit of their respective successors and assigns hereunder.

SECTION 14. Termination. This Agreement shall terminate on the fourth Business Day after the Expiration Date. Notwithstanding the foregoing, this Agreement will terminate on any earlier date upon which all Units have ceased to be outstanding.

SECTION 15. Governing Law. This Agreement and each Unit Certificate issued hereunder shall be deemed to be a contract made under the laws of the State of New York and shall be governed by and construed in accordance with the laws of said State, without regard to the conflict of law rules thereof.

SECTION 16. Benefits of This Agreement. Nothing in this Agreement shall be construed to give to any person or corporation other than the Company, the Unit Agent and the registered Holders of the Unit Certificates from time to time any legal or equitable right, remedy or claim under this Agreement; but this Agreement shall be for the sole and exclusive benefit of the Company, the Unit Agent and the registered Holders of the Unit Certificates.

SECTION 17. Counterparts. This Agreement may be executed in any number of counterparts and each of such counterparts shall for all purposes be deemed to be an original, and all such counterparts shall together constitute but one and the same instrument.

SECTION 18. Force Majeure. Notwithstanding anything to the contrary contained herein, the Unit Agent shall not be liable for any delays or failures in performance resulting from acts beyond its reasonable control including, without limitation, acts of God, terrorist acts, shortage of supply, breakdowns or malfunctions, interruptions or malfunction of computer facilities, or loss of data due to power failures or mechanical difficulties with information storage or retrieval systems, labor difficulties, war, or civil unrest.

SECTION 19. Priorities. In the event of any conflict, discrepancy, or ambiguity between the terms and conditions contained in this Agreement and any schedules or attachments hereto, the terms and conditions contained in this Agreement shall take precedence.

Attn: Reorganization Departments

Ladies and Gentlemen:

In connection with our proposed purchase of units (the “Securities”) of Louisiana-Pacific Corporation (the “Company”), we confirm that:

1. We understand that the Securities have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), and, unless so registered, may not be offered, sold or otherwise transferred except as permitted in the following sentence. We agree on our own behalf and on behalf of any investor account for which we are purchasing Securities to offer, sell or otherwise transfer such Securities prior to the date which is one year after the later of the date of original issue and the last date on which the Company or any affiliate of the Company was the owner of such Securities (or any predecessor Securities) (the “Resale Restriction Termination Date”) only (a) to the Company, (b) pursuant to a registration statement which has been declared effective under the Securities Act, (c) for so long as the Securities are eligible for resale pursuant to Rule 144A under the Securities Act, to a person we reasonably believe is a qualified institutional buyer as defined in Rule 144A (a “QIB”) that purchases for its own account or for the account of a QIB and to whom notice is given that the transfer is being made in reliance on Rule 144A, (d) pursuant to offers and sales that occur outside the United States within the meaning of Regulation S under the Securities Act, (e) to an institutional “accredited investor” within the meaning of subparagraph (a)(1), (a)(2), (a)(3) or (a)(7) of Rule 501 under the Securities Act that is acquiring the Securities for its own account or for the account of such an institutional “accredited investor”, for investment purposes and not with a view to, or for offer or sale in connection with, any distribution in violation of the Securities Act, or (f) pursuant to another available exemption from the registration requirements of the Securities Act, subject in each of the foregoing cases to any requirement of law that the disposition of our property or the property of such investor account or accounts be at all times within our or their control and to compliance with any applicable state securities laws. The foregoing restrictions on resale will not apply subsequent to the Resale Restriction Termination Date. If any resale or other transfer of the Securities is proposed to be made pursuant to clause (e) above prior to the Resale Restriction Termination Date, the transferor shall deliver a letter from the transferee substantially in the form of this letter to the unit agent under the Unit Agreement pursuant to which the Securities were issued (the “Unit Agent”) which shall provide, among other things, that the transferee is an institutional “accredited investor” within the meaning of subparagraph (a)(1), (a)(2), (a)(3) or (a)(7) of Rule 501 under the Securities Act and that it is acquiring such Securities for investment purposes and not for distribution in violation of the Securities Act. The Unit Agent and the Company reserve the right prior to any offer, sale or other transfer prior to the Resale Restriction Termination Date of the Securities pursuant to clause (c), (d), (e) or (f) above to require the delivery of a written opinion of counsel, certifications, and or other information satisfactory to the Company and the Unit Agent.

D-1

2. We are an institutional “accredited investor” (as defined in Rule 501(a)(1), (a)(2), (a)(3) or (a)(7) of Regulation D under the Securities Act) purchasing for our own account or for the account of such an institutional “accredited investor”, and we are acquiring the Securities for investment purposes and not with a view to, or for offer or sale in connection with, any distribution in violation of the Securities Act and we have such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of our investment in the Securities, and we and any accounts for which we are acting are each able to bear the economic risk of our or its investment for an indefinite period.

3. We are acquiring the Securities purchased by us for our own account or for one or more accounts as to each of which we exercise sole investment discretion.

4. You and your counsel are entitled to rely upon this letter and you are irrevocably authorized to produce this letter or a copy hereof to any interested party in any administrative or legal proceeding or official inquiry with respect to the matters covered hereby.
