ANNEX A

Pursuant to Sections 2.1 and 2.3 of the Indenture, dated as of November 14, 2005 (the “Indenture”), among Plum Creek Timberlands, L.P. (the “Issuer”), Plum Creek Timber Company, Inc. (the “Guarantor”) and U.S. Bank National Association, as trustee (the “Trustee”), the terms of a series of Securities to be issued pursuant to the Indenture are as follows:

1.                                    Designation.  The designation of the Securities is the “5.875% Notes due 2015” (herein referred to as the “Notes”).

2.                                       Initial Aggregate Principal Amount.  The Notes shall be limited in initial aggregate principal amount to $300,000,000 (except for Notes authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other Notes pursuant to Section 2.8, 2.9, 2.11, 8.5 or 12.3 of the Indenture).

3.                                       Maturity.  The date on which the principal of the Notes is payable is November 15, 2015 (the “Maturity Date”).

4.                                       Rate of Interest; Interest Payment Date; Regular Record Dates.  Each Note shall bear interest at the rate of 5.875% per year, until the principal thereof is paid.  Such interest shall be payable semi-annually in arrears on May 15 and November 15 of each year (each, an “Interest Payment Date”), commencing on May 15, 2006, to the persons in whose names the Notes are registered at the close of business on the immediately preceding May 1 and November 1 (each, a “record date”), as the case may be.  Interest on the Notes shall accrue from and including the immediately preceding Interest Payment Date in respect of which interest has been paid or duly made available for payment (or from and including the date of issue, if no interest has been paid or duly made available for payment with respect to the Notes) to but excluding the applicable Interest Payment Date or the Maturity Date, as the case may be.  Interest on the Notes shall be computed on the basis of a 360-day year comprised of twelve 30-day months.  If any Interest Payment Date or the Maturity Date falls on a day that is not a Business Day, the required payment of principal, Make-Whole Amount (as defined below), if any, and/or interest payable on such date will be made on the next succeeding Business Day as if made on the date such payment was due, and no interest will accrue on such payment for the period from and after such Interest Payment Date or maturity date, as the case may be, to the date of such payment on the next succeeding Business Day.

5.                                    Place of Payment.  Payments of principal, Make-Whole Amount, if any, and interest on the Notes shall be payable, at the office of the Issuer’s paying agent maintained in the Borough of Manhattan, The City of New York.  Payment of principal of, or Make-Whole Amount, if any, on a

A-1

definitive Note may be made only against surrender of the Note to the Issuer’s paying agent.  The Issuer may, however, make payments of interest by mailing checks to the address of the holder appearing in the security register maintained by the registrar.  However, while any Notes are represented by a Registered Global Security, payment of principal of, Make-Whole Amount, if any, or interest on the Notes may be made by wire transfer to the account of the Depositary or its nominee.

6.                                       Optional Redemption.

(a)                                  The Issuer may redeem the Notes at any time in whole or from time to time in part at a redemption price equal to the sum of 100% of the aggregate principal amount of the Notes being redeemed, accrued but unpaid interest on those Notes to, but not including, the redemption date, and the Make-Whole Amount, if any.  The Issuer will, however, pay the interest installment due on any Interest Payment Date that occurs on or before a redemption date to the registered holders of the Notes as of the close of business on the record date immediately preceding that Interest Payment Date.  If the Issuer has given notice as provided in the Indenture and made funds available for the redemption of any Notes called for redemption on the redemption date referred to in that notice, those Notes will cease to bear interest on that redemption date and the only right of the holders of those Notes will be to receive payment of the redemption price.  Notice of redemption and partial redemption shall be as provided in the Indenture.

(b)                                 As used herein, the following terms shall have the respective meanings specified:

(i)                                     “Make-Whole Amount” means, in connection with any optional redemption, the excess, if any, of (a) the aggregate present value as of the date of such redemption of each dollar of principal being redeemed and the amount of interest, exclusive of interest accrued to the date of redemption, that would have been payable in respect of each such dollar if such redemption had not been made, determined by discounting, on a semi-annual basis (assuming a 360-day year of twelve 30-day months), such principal and interest at the Reinvestment Rate, determined on the third Business Day preceding the date notice of such redemption is given, from the respective dates on which such principal and interest would have been payable if such redemption had not been made, to the date of redemption,

A-2

over (b) the aggregate principal amount of the Notes being redeemed.

(ii)                                  “Reinvestment Rate” means 0.25% plus the arithmetic mean of the yields under the heading “Week Ending” published in the most recent Statistical Release under the caption “Treasury Constant Maturities” for the maturity, rounded to the nearest month, corresponding to the remaining life to maturity, as of the payment date of the principal amount of the Notes being redeemed.  If no maturity exactly corresponds to such maturity, yields for the two published maturities most closely corresponding to such maturity shall be calculated pursuant to the immediately preceding sentence and the Reinvestment Rate shall be interpolated or extrapolated from such yields on a straight-line basis, rounding in each of such relevant periods to the nearest month.  For the purposes of calculating the Reinvestment Rate, the most recent Statistical Release published prior to the date of determination of the Make-Whole Amount shall be used.  If the format or content of the Statistical Release changes in a manner that precludes determination of the Treasury yield in the above manner, then the Treasury yield shall be determined in the manner that most closely approximates the above manner, as reasonably determined by the Issuer.

(iii)                               “Statistical Release” means the statistical release designated “H.15(519)” or any successor publication which is published weekly by the Federal Reserve System and which reports yields on actively traded United States government securities adjusted to constant maturities, or, if such statistical release is not published at the time of any required determination under the indenture, then such other reasonably comparable index which shall be designated by the Issuer.

7.                                       Mandatory Redemption.  The Notes are not mandatorily redeemable and are not entitled to the benefit of a sinking fund or any analogous provisions.

8.                                       Ranking Security.  The Notes are unsecured obligations of the Issuer and rank equally with other unsecured indebtedness of the Issuer that is not subordinated to the Notes.

A-3

9.                                       Amount Payable Upon Acceleration.  100% of the principal of and accrued interest, if any, on the Notes shall be payable upon declaration of acceleration pursuant to Section 5.1 of the Indenture.

10.                                 Payment Currency - Election.  The principal of, Make-Whole Amount, if any, and interest on the Notes shall not be payable in a currency other than Dollars.

11.                                 Payment Currency - Index.  The principal of, Make-Whole Amount, if any, and interest on the Notes shall not be determined with reference to an index based on a coin or currency.

12.                                 Registered Securities.  The Notes shall be issued only as Registered Securities.  The Notes shall be issuable as Registered Global Securities.

13.                                 Additional Amounts.  The Issuer shall not pay additional amounts on the Notes held by a Person that is not a U.S. Person in respect of taxes or similar charges withheld or deducted.

14.                                 Definitive Certificates.  Section 2.8 of the Indenture will govern the transferability of the Notes in definitive form.

15.                                 Registrar; Paying Agent; Depositary.  The Trustee shall initially serve as the registrar and the paying agent for the Notes.  The Depository Trust Company shall initially serve as the Depositary for the Registered Global Security representing the Notes.

17.                                 Covenants.  There shall be the following additions to the covenants of the Issuer set forth in Article III of the Indenture with respect to the Notes:

(vii)                           “Secured Debt” means any Debt of the Issuer or any of its Restricted Subsidiaries that is secured by a Lien on any Principal Property or on any stock of, or on any Debt of, a Restricted Subsidiary.  Secured Debt does not include Debt secured by:  (a) Liens existing at the time of acquisition by the Issuer or any of its Restricted Subsidiaries on Principal Property or any stock of, or on any Debt, of a Restricted Subsidiary, whether or not assumed; (b) Liens to secure

5.875% Notes due 2015

PLUM CREEK TIMBERLANDS, L.P., a limited partnership duly organized and existing under the laws of the State of Delaware (herein referred to as the “Issuer,” which term includes any successor Person under the Indenture hereinafter referred to) for value received, hereby promises to pay to CEDE & CO., or its registered assigns, the principal sum of THREE HUNDRED MILLION DOLLARS ($300,000,000) on November 15, 2015 (the “Stated Maturity Date” with respect to the principal of this Note), unless previously redeemed on any Redemption Date (as defined below), in accordance with the provisions set forth on the reverse hereof (the Stated Maturity Date or any Redemption Date is referred herein as the “Maturity Date” with respect to principal repayable on such date) and to pay interest thereon semiannually in arrears on May 15 and November 15 of each year, commencing on May 15, 2006 (each, an “Interest Payment Date”), at the rate of 5.875% per annum, until payment of said principal has been made or duly provided for.  Interest on this Note payable on an Interest Payment Date will accrue from and including the immediately preceding Interest Payment Date to which interest has been paid or duly provided for, or from and including November 14, 2005 if no interest has been paid or duly provided for, to but excluding the applicable Interest Payment Date or the Maturity Date, as the case may be.  Interest on this Note will be computed on the basis of a 360-day year consisting of twelve 30-day months.

Capitalized terms used but not otherwise defined herein shall have the respective meanings assigned to them in the Indenture (as defined on the reverse hereof).

The interest so payable and punctually paid or duly provided for on any Interest Payment Date will be paid to the Holder in which name this Note (or one or more predecessor Notes) is registered in the Security register at the close of business on the “Regular Record Date” for such payment, which shall be

May 1 or November 1, as the case may be, immediately preceding such Interest Payment Date (regardless of whether such day is a Business Day (as defined below)).  Any such interest not so punctually paid or duly provided for shall forthwith cease to be payable to the Holder on such Regular Record Date, and shall be paid to the Person in whose name this Note (or one or more predecessor Notes) is registered at the close of business on a subsequent “Special Record Date” for the payment of such defaulted interest (which shall be not more than 5 Business Days prior to the date of the payment of such defaulted interest) established by notice given by mail by or on behalf of the Issuer to the Holders of the Notes not less than 15 calendar days preceding such subsequent Special Record Date, or may be paid at any time in any other lawful manner, all as more fully provided in the Indenture.

The principal of, and the Make-Whole Amount (as defined on the reverse hereof), if any, with respect to, this Note payable on the Maturity Date will be paid against presentation and surrender of this Note at the office or agency of the Issuer maintained for that purpose in the Borough of Manhattan, The City of New York.  The Issuer hereby initially designates the Corporate Trust Office of the Trustee (as defined on the reverse hereof) at 100 Wall Street, 16^th Floor, New York, New York 10004 as the office to be maintained by it where Notes may be presented for payment, registration of transfer or exchange and where notices or demands to or upon the Issuer in respect of the Notes or the Indenture may be served.

If any Interest Payment Date or the Maturity Date falls on a day that is not a Business Day, the payment required to be made on such date will, instead, be made on the next Business Day with the same force and effect as if it were made on the date such payment was due, and no interest shall accrue on the amount so payable for the period from and after such Interest Payment Date or the Maturity Date, as the case may be.  “Business Day” means any day, other than a Saturday, a Sunday or other day on which banking institutions in The City of New York are authorized or obligated by law, regulation or executive order to be closed.

Payments of principal, Make-Whole Amount, if any, and interest in respect of this Note will be made in such coin or currency of the United States of America as at the time of payment is legal tender for the payment of public and private debts (i) in the case of payments on the Maturity Date, in immediately available funds and (ii) in the case of payments of interest on an Interest Payment Date other than the Maturity Date, at the option of the Issuer, by check mailed to the Holder entitled thereto at the applicable address appearing in the Security register or by transfer of immediately available funds to an account maintained by the payee with a bank located in the United States of America; provided, however, that so long as Cede & Co. is the Holder of this Note, payments of interest on an Interest Payment Date may be made in immediately available funds.

Reference is made to the further provisions of this Note set forth on the reverse hereof.  Such further provisions shall for all purposes have the same effect as though fully set forth at this place.

This Note shall not be entitled to the benefits of the Indenture or the Guarantee (as defined on the reverse of this Note) or be valid or become obligatory for any purpose until the certificate of authentication hereon shall have been executed by manual signature by the Trustee.

IN WITNESS WHEREOF, the Issuer has caused this instrument to be duly executed, manually or by facsimile by an authorized signatory.

PLUM CREEK TIMBERLANDS, L.P.

5.875% Note due 2015

This Note is one of a duly authorized issue of senior debt securities of the Issuer (hereinafter called the “Securities”) of the series hereinafter specified, all issued or to be issued under and pursuant to an Indenture, dated as of November 14, 2005 (the “Indenture”), duly executed and delivered by the Issuer and Plum Creek Timber Company, Inc., as guarantor (the “Guarantor”), to U.S. Bank National Association, as trustee (the “Trustee,” which term includes any successor trustee under the Indenture with respect to the series of Securities of which this Note is a part), and reference is hereby made to the Indenture, and all modifications and amendments and indentures supplemental thereto relating to the Notes, made for a description of the rights, limitations of rights, obligations, duties, and immunities thereunder of the Trustee, the Issuer, the Guarantor and the Holders of the Notes and the terms upon which the Notes are authenticated and delivered.  The Securities may be issued in one or more series, which different series may be issued in various aggregate principal amounts, may mature at different times, may accrue interest (if any) at different rates or formulas and may otherwise vary as provided in the Indenture.  This Note is one of a series of Securities designated as the “5.875% Notes due 2015” (collectively, the “Notes”) of the Issuer, limited (except as permitted under the Indenture) in aggregate principal amount to $300,000,000.

Payments of principal, Make-Whole Amount, if any, and interest in respect of the Notes will be fully and unconditionally guaranteed by the Guarantor.

The Issuer may redeem this Note, at any time in whole or from time to time in part, at the option of the Issuer, at a price equal to the sum of 100% of the aggregate principal amount of the Notes being redeemed, accrued but unpaid interest on those Notes to but excluding the date fixed for redemption date (the “Redemption Date”), and the Make-Whole Amount, if any, as defined below (the “Redemption Price”); provided, however, that interest installments due on an Interest Payment Date which is on or prior to the Redemption Date will be payable to the Holder hereof (or one or more predecessor Notes) as of the close of business on the Regular Record Date preceding such Interest Payment Date.

If notice has been given as provided in the Indenture and funds for the redemption of this Note or any part thereof called for redemption shall have been made available on the Redemption Date, this Note or such part thereof will cease to bear interest on the Redemption Date referred to in such notice and the only right of the Holder will be to receive payment of the Redemption Price.  Notice of any optional redemption of any Notes will be given to the Holder hereof (in accordance with the provisions of the Indenture), not more than 60 nor less than 30 days prior to the Redemption Date.  The notice of redemption will specify, among other things, the Redemption Date, the Redemption Price and the principal amount of Notes to be redeemed.  In the event of redemption of this Note in part only, a new Note of like tenor for the unredeemed portion hereof and otherwise having the same terms and provisions as this Note shall be issued by the Issuer in the name of the Holder hereof upon the presentation and surrender hereof.

“Make-Whole Amount” means, in connection with any optional redemption, the excess, if any, of (a) the aggregate present value as of the date of such redemption of each dollar of principal being

redeemed and the amount of interest, exclusive of interest accrued to the Redemption Date, that would have been payable in respect of each such dollar if such redemption had not been made, determined by discounting, on a semi-annual basis (assuming a 360-day year of twelve 30-day months), such principal and interest at the Reinvestment Rate, determined on the third Business Day preceding the date notice of such redemption is given, from the respective dates on which such principal and interest would have been payable if such redemption had not been made, to the date of redemption, over (b) the aggregate principal amount of the Notes being redeemed.

“Reinvestment Rate” means 0.25% plus the arithmetic mean of the yields under the heading “Week Ending” published in the most recent Statistical Release under the caption “Treasury Constant Maturities” for the maturity, rounded to the nearest month, corresponding to the remaining life to maturity, as of the payment date of the principal amount of the Notes being redeemed.  If no maturity exactly corresponds to such maturity, yields for the two published maturities most closely corresponding to such maturity shall be calculated pursuant to the immediately preceding sentence and the Reinvestment Rate shall be interpolated or extrapolated from such yields on a straight-line basis, rounding in each of such relevant periods to the nearest month.  For the purposes of calculating the Reinvestment Rate, the most recent Statistical Release published prior to the date of determination of the Make-Whole Amount shall be used.  If the format or content of the Statistical Release changes in a manner that precludes determination of the Treasury yield in the above manner, then the Treasury yield shall be determined in the manner that most closely approximates the above manner, as reasonably determined by the Issuer.

“Statistical Release” means the statistical release designated “H.15(519)” or any successor publication which is published weekly by the Federal Reserve System and which reports yields on actively traded United States government securities adjusted to constant maturities, or, if such statistical release is not published at the time of any required determination under the indenture, then such other reasonably comparable index which shall be designated by the Issuer.

This Note is not mandatorily redeemable and is not entitled to the benefit of a sinking fund or any analogous provisions.

In case an Event of Default with respect to this Note shall have occurred and be continuing, the principal hereof may be (and, in certain cases, shall be) declared, and upon such declaration shall become, due and payable, in the manner, with the effect, and subject to the conditions, provided in the Indenture.
