Ladies and Gentlemen:

Plum Creek Timberlands, L.P., a Delaware limited partnership (the “Operating Partnership”), and Plum Creek Timber Company, Inc., a Delaware corporation (the “Company”), confirm their respective agreements with the Underwriters named in Schedule A hereto (collectively, the “Underwriters,” which term shall also include any underwriter substituted as hereinafter provided in Section 10 hereof), for whom Banc of America Securities LLC (“Banc of America Securities”) and Goldman, Sachs & Co. (“Goldman Sachs”) are acting as representatives (in such capacity, the “Representatives”), with respect to the sale by the Operating Partnership and the purchase by the Underwriters, acting severally and not jointly, of the respective principal amount of the Operating Partnership’s 5.875% Notes due 2015 (the “Debt Securities”) listed in Schedule A hereto.

The Debt Securities will be fully and unconditionally guaranteed as to payment of the principal of, and premium, if any, and interest on, the Debt Securities (the “Guarantee” and, together with the Debt Securities, the “Securities”) by the Company. The Securities will be issued pursuant to an Indenture, dated as of November 14, 2005, among the Operating Partnership, the Company and U.S. Bank National Association, as trustee (the “Trustee”), as supplemented by an officer’s certificate, dated November 14, 2005 (such Indenture as amended or supplemented is herein referred to as the “Indenture”).

The Company and the Operating Partnership have prepared and filed with the Securities and Exchange Commission (the “Commission”) in accordance with the provisions of Securities Act of 1933, as amended (the “1933 Act”), and the rules and regulations of the Commission thereunder (the “1933 Act Regulations”), registration statement on Form S-3 Nos. 333-118516 and 333-118516-01, relating to, among other things, certain securities (the “Shelf Securities”), including the Securities, to be issued from time to time by the Company and the Operating Partnership. Promptly after execution and delivery of this Agreement, the Company and the Operating Partnership will prepare and file a prospectus relating to the Securities in

accordance with the provisions of Rule 430A (“Rule 430A”) of the 1933 Act Regulations and paragraph (b) of Rule 424 (“Rule 424(b)”) of the 1933 Act Regulations.

If at any time when a prospectus is required by the 1933 Act to be delivered in connection with sales of the Securities, any event shall occur or condition shall exist as a result of which it is necessary, in the reasonable opinion of counsel for the Underwriters and for the Operating Partnership and the Company, to amend the Registration Statement or amend or supplement the Prospectus in order that the Prospectus will not include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein not misleading in the light of the circumstances existing at the time it is delivered to a purchaser, or if it shall be necessary, in the opinion of such counsel, at any such time to amend the Registration Statement or amend or supplement the Prospectus in order to comply with the requirements of the 1933 Act or the 1933 Act Regulations, the Operating Partnership and the Company will promptly prepare and file with the Commission, subject to Section 3(b), such amendment or supplement as may be necessary to correct such statement or omission or to make the Registration Statement or the Prospectus comply with such requirements, and the Operating Partnership and the Company will furnish to the Underwriters such number of copies of such amendment or supplement as the Underwriters may reasonably request.

(f) Blue Sky Qualifications. The Operating Partnership and the Company will use their respective reasonable best efforts, in cooperation with the Underwriters, to qualify the Securities for offering and sale under the applicable securities laws of such states and other jurisdictions (domestic or foreign) as the Representatives may designate and to maintain such qualifications in effect for a period of not less than one year from the later of the effective date of the Registration Statement and any Rule 462(b) Registration Statement; provided, however, that neither the Operating Partnership nor the Company shall be obligated to file any general consent to service of process or to qualify as a foreign corporation or as a dealer in securities in any jurisdiction in which it is not so qualified or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise so subject. In each jurisdiction in which the Securities have been so qualified, the Operating Partnership and the Company will file such statements and reports as may be required by the laws of such jurisdiction to continue such qualification in effect for a period of not less than one year from the effective date of the Registration Statement.

(g) Rule 158. The Company will timely file such reports pursuant to the 1934 Act as are necessary in order to make generally available to its respective securityholders as soon as practicable an earnings statement for the purposes of, and to provide the benefits contemplated by, the last paragraph of Section 11(a) of the 1933 Act.

(h) Restriction on Sale of Securities. Between the date of this Agreement and the Closing Time, neither the Operating Partnership nor the Company will, without the Representatives’ prior written consent, offer to sell, enter into any agreement to sell or sell any debt securities (other than borrowings under any revolving credit agreement).

(i) Reporting Requirements. The Company, during the period when the Prospectus is required to be delivered under the 1933 Act or the 1934 Act, will file all documents required to

be filed with the Commission pursuant to the 1934 Act within the time periods required by the 1934 Act and the 1934 Act Regulations.

(j) DTC. The Operating Partnership and the Company shall use their reasonable best efforts in cooperation with the Underwriters to permit the Securities to be eligible for clearance, settlement and trading through DTC.

(k) Ratings. The Operating Partnership and the Company will use their reasonable best efforts to enable Standard & Poor’s Ratings Services (“S&P”), Moody’s Investors Service, Inc. (“Moody’s”) and Fitch Ratings (“Fitch”) to provide their respective credit ratings of the Securities.

(l) Use of Proceeds. The Operating Partnership agrees to use the net proceeds from the sale of the Debt Securities in the manner described under “Use of Proceeds” in the Prospectus.

(m) Notification of Certain Events. Prior to the Closing Time, the Operating Partnership and the Company will notify the Representatives immediately if any event occurs that renders any of the representations and warranties of the Operating Partnership and the Company contained herein inaccurate or incomplete.

SECTION 4. Payment of Expenses.

The Operating Partnership and the Company will pay or cause to be paid all expenses incident to the performance of their respective obligations under this Agreement, including (i) the preparation, printing and filing of the Registration Statement (including financial statements and exhibits) as originally filed and of each amendment thereto, (ii) the preparation, issuance and delivery of the certificates for the Securities to the Underwriters, (iii) the fees and disbursements of their counsel, accountants and other advisors, (iv) subject to receipt of documentation (such documentation to be sufficient for this purpose if it is of a type customarily obtained by the Underwriters), the qualification of the Securities under securities laws in accordance with the provisions of Section 3(f) hereof, including filing fees and the reasonable fees and disbursements of counsel for the Underwriters in connection therewith and in connection with the preparation of the Blue Sky Survey and any supplement thereto not to exceed $5,000, (v) the printing and delivery to the Underwriters of copies of preliminary prospectus and the Prospectus and any amendments or supplements thereto, (vi) the preparation, printing and delivery to the Underwriters of copies of the Blue Sky Survey and any supplement thereto, (vii) any fees charged by a “nationally recognized statistical rating organization” (as such term is defined by the Commission for purposes of Rule 436(g)(2) under the 1933 Act) for the rating of the Securities, (viii) the fees and expenses of the Trustee, including the reasonable fees and disbursements of counsel for the Trustee, in connection with the Indenture and the Securities, (ix) all expenses and fees incurred in connection with the clearance, settlement and trading of the Securities through DTC, (x) all expenses and fees incurred in connection with the application to obtain CUSIP numbers for the Securities, (xi) subject to receipt of documentation (such documentation to be sufficient for this purpose if it is of a type customarily obtained by the Underwriters), the filing fees incident to, and the reasonable fees and disbursements of counsel to the Underwriters in connection with, the review by the National Association of Securities

In giving such opinion such counsel may rely, as to all matters governed by the laws of jurisdictions other than the law of the State of New York and the federal law of the United States and the General Corporation Law of the State of Delaware, upon the opinions of counsel satisfactory to the Representatives. Such counsel may also state that, insofar as such opinion involves factual matters, they have relied, to the extent they deem proper, upon certificates of officers and other representatives of the Operating Partnership, Company and their respective subsidiaries and certificates of public officials.

(f) Accountant’s Comfort Letter.

Agreement, there shall not have occurred a downgrading in, or withdrawal of, any rating assigned to the Securities or any other securities of the Operating Partnership or the Company by any nationally recognized statistical rating organization, and no such rating organization shall have publicly announced that it has under surveillance or review any rating of the Securities or any other securities of the Operating Partnership or the Company other than with positive implications.

(j) Termination of Agreement. If any condition specified in this Section shall not have been fulfilled when and as required to be fulfilled, this Agreement may be terminated by the Representatives by notice to the Operating Partnership and the Company at any time at or prior to Closing Time, and such termination shall be without liability of any party to any other party except as provided in Section 4 and except that Sections 1, 6, 7, 8 and 13 shall survive any such termination and remain in full force and effect.

SECTION 6. Indemnification.

(a) Indemnification of Underwriters by the Operating Partnership and the Company. Each of the Operating Partnership and the Company, jointly and severally, agrees to indemnify and hold harmless each Underwriter and each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act to the extent and in the manner set forth in clauses (i), (ii) and (iii) as follows:

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), including the Rule 430A Information, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact included in any preliminary prospectus or the Prospectus (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ii) against any and all loss, liability, claim, damage and expense whatsoever (which, in the case of legal expenses, must be reasonable), as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based, in each case, upon any such untrue statement or omission, or

any such alleged untrue statement or omission; provided that (subject to Section 6(d) below) any such settlement is effected with the written consent of the Operating Partnership and the Company; and

(iii) against any and all expense whatsoever, as incurred (including, subject to Section 6(c), the fees and disbursements of counsel chosen by the Representatives), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Operating Partnership and the Company by any Underwriter through the Representatives expressly for use in the Registration Statement (or any amendment thereto), preliminary prospectus or the Prospectus (or any amendment or supplement thereto).

(b) Indemnification of the Operating Partnership, the Company, Directors and Officers. Each Underwriter, severally and not jointly, agrees to indemnify and hold harmless the Operating Partnership, the Company, the Company’s directors, each of the Company’s officers who signed the Registration Statement, and each person, if any, who controls the Operating Partnership or the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto) or any preliminary prospectus or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to the Operating Partnership and the Company by such Underwriter through the Representatives expressly for use in the Registration Statement (or any amendment thereto) or such preliminary prospectus or the Prospectus (or any amendment or supplement thereto).

(c) Actions against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. If it so elects within a reasonable time after receipt of such notice, upon providing notice thereof to the indemnified party, an indemnifying party shall be entitled to participate in such action and, to the extent that it shall wish, jointly with any other indemnifying parties receiving the notice required under the first sentence hereof, assume the defense of such action with counsel chosen by it (provided that such counsel is approved, in their reasonable discretion, by the indemnified parties who are defendants in such action) unless such indemnified parties reasonably object to such assumption on the ground that there may be legal defenses available to them that are different from or in addition to those available to such indemnifying party. In the absence of such an

election by an indemnifying party within a reasonable period of time after receipt of such notice to assume the defense of such an action or, in the event of a failure to assume the defense of such action within a reasonable period of time, in the case of parties indemnified pursuant to Sections 6(a) above, counsel to the indemnified parties shall be selected by the Representatives, and, in the case of parties indemnified pursuant to Section 6(b) above, counsel to the indemnified parties shall be selected by the Company. If an indemnifying party assumes the defense of such action, the indemnifying parties shall not be liable for any fees and expenses of counsel for the indemnified parties incurred thereafter in connection with such action. An indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 6 or Section 7 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d) Settlement without Consent if Failure to Reimburse. Subject to Section 6(c), if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(ii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

SECTION 7. Contribution. If the indemnification provided for in Section 6 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Operating Partnership and the Company on the one hand and the Underwriters on the other hand from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Operating Partnership and the Company on the one hand and the Underwriters on the other hand in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Operating Partnership and the Company on the one hand and the Underwriters on the other hand in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Operating Partnership and the total underwriting discount received by the Underwriters, in each case as set forth on the cover of the Prospectus, bear to the aggregate initial public offering price of the Securities as set forth on such cover.

The relative fault of the Operating Partnership and the Company on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Operating Partnership or the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Operating Partnership, the Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 7. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission.

No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 7, each person, if any, who controls an Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement and each person, if any, who controls the Operating Partnership or the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Operating Partnership or the Company, as the case may be. The Underwriters’ respective obligations to contribute pursuant to this Section 7 are several in proportion to the number of Securities set forth opposite their respective names in Schedule A hereto and not joint.

SECTION 8. Representations, Warranties and Agreements to Survive Delivery. All representations, warranties and agreements contained in this Agreement or in certificates of officers or other representatives of the Operating Partnership or the Company or any of their respective subsidiaries submitted pursuant hereto, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or controlling person, or by or on behalf of the Operating Partnership or the Company, and shall survive delivery of the Securities to the Underwriters.

SECTION 9. Termination of Agreement.

(a) Termination; General. The Representatives may terminate this Agreement, by notice to the Operating Partnership and the Company, at any time at or prior to Closing Time (i) if there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the Prospectus, any Material Adverse Effect, or (ii) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Representatives, impracticable or inadvisable to market the Securities or to enforce contracts for the sale of the Securities, or (iii) if trading in any securities of the Operating Partnership or the Company has been suspended or materially limited by the Commission or the New York Stock Exchange or the Pacific Exchange, or if trading generally on the American Stock Exchange or the New York Stock Exchange or in the Nasdaq National Market has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by such system or by order of the Commission, the National Association of Securities Dealers, Inc. or any other governmental authority or a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States, or (iv) if a banking moratorium has been declared by either U.S. Federal or New York authorities.

(b) Liabilities. If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Sections 1, 6, 7, 8 and 13 shall survive such termination and remain in full force and effect.

SECTION 10. Default by One or More of the Underwriters. If one or more of the Underwriters shall fail at Closing Time or a Date of Delivery to purchase the Securities which it or they are obligated to purchase under this Agreement (the “Defaulted Securities”), the Representatives shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representatives shall not have completed such arrangements within such 24-hour period, then:

(a) if the number of Defaulted Securities does not exceed 10% of the aggregate principal amount of the Securities to be purchased on such date, each of the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the

full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters, or

(b) if the number of Defaulted Securities exceeds 10% of the aggregate principal amount of the Securities to be purchased on such date, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter.

No action taken pursuant to this Section shall relieve any defaulting Underwriter from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement, then the Representatives or the Operating Partnership shall have the right to postpone the Closing Time for a period not exceeding seven days in order to effect any required changes in the Registration Statement or the Prospectus or in any other documents or arrangements. As used herein, the term “Underwriter” includes any person substituted for an Underwriter under this Section 10.

SECTION 11. Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication. Notices to the Underwriters shall be directed to the Representatives at c/o Banc of America Securities LLC, 40 West 57^th Street, 27^th Floor, New York, New York 10019, attention of High Grade Debt Capital Markets Transaction Management, and Goldman Sachs & Co., One New York Plaza, 42^nd Floor, New York, New York 10004, attention of Registration Department, with a copy to Sidley Austin Brown & Wood LLP, 787 Seventh Avenue, New York, New York 10019, attention of Edward F.

SECTION 12. Parties. This Agreement shall inure to the benefit of and be binding upon the Underwriters, the Operating Partnership and the Company and their respective successors. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the Underwriters, the Operating Partnership and the Company and their respective successors and the controlling persons and officers and directors referred to in Sections 6 and 7 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the Underwriters, the Operating Partnership and the Company and their respective successors, and said controlling persons and officers and directors and their heirs and legal representatives, and for the benefit of no other person, firm or corporation.
