HOWEVER, that:

          (1)    if Boise Holdings, Timber Holdings or any Restricted Subsidiary
     has Incurred any Indebtedness since the beginning of such period that
     remains outstanding or if the transaction giving rise to the need to
     calculate the Consolidated Coverage Ratio is an Incurrence of Indebtedness,
     or both, EBITDA and Consolidated Interest Expense for such period shall be
     calculated after giving effect on a PRO FORMA basis to such Indebtedness as

     Indebtedness Incurred under any revolving credit facility unless such
     Indebtedness has been permanently repaid and has not been replaced) on the
     date of the transaction giving rise to the need to calculate the
     Consolidated Coverage Ratio, EBITDA and Consolidated Interest Expense for
     such period shall be calculated on a PRO FORMA basis as if such discharge
     had occurred on the first day of such period and as if Boise Holdings,
     Timber Holdings or such Restricted Subsidiary had not earned the interest
     income actually earned during such period in respect of cash or Temporary
     Cash Investments used to repay, repurchase, defease or otherwise discharge
     such Indebtedness;

          (3)    if since the beginning of such period Boise Holdings, Timber
     Holdings or any Restricted Subsidiary shall have made any Asset
     Disposition, EBITDA for such period shall be reduced by an amount equal to
     EBITDA (if

<Page>

                                                                               7

     positive) directly attributable to the assets which are the subject of such
     Asset Disposition for such period, or increased by an amount equal to
     EBITDA (if negative), directly attributable thereto for such period and
     Consolidated Interest Expense for such period shall be reduced by an amount
     equal to the Consolidated Interest Expense directly attributable to any
     Indebtedness of Boise Holdings, Timber Holdings or any Restricted
     Subsidiary repaid, repurchased, defeased or otherwise discharged with
     respect to Boise Holdings, Timber Holdings and their continuing Restricted
     Subsidiaries in connection with such Asset Disposition for such period (or,
     if the Capital Stock of any Restricted Subsidiary is sold, the Consolidated
     Interest Expense for such period directly attributable to the Indebtedness
     of such Restricted Subsidiary to the extent Boise Holdings, Timber Holdings
     and their continuing Restricted Subsidiaries are no longer liable for such
     Indebtedness after such sale);

          (4)    if since the beginning of such period Boise Holdings, Timber
     Holdings or any Restricted Subsidiary (by merger or otherwise) shall have
     made an Investment in any Restricted Subsidiary (or any Person which
     becomes a Restricted Subsidiary) or an acquisition of assets, including any
     acquisition of assets occurring in connection with a transaction requiring
     a calculation to be made hereunder, which constitutes all or substantially
     all of an operating unit of a business, EBITDA and Consolidated Interest
     Expense for such period shall be calculated after giving PRO FORMA effect
     thereto (including the Incurrence of any Indebtedness) as if such
     Investment or acquisition had occurred on the first day of such period;

          (5)    if since the beginning of such period any Person (that
     subsequently became a Restricted Subsidiary or was merged with or into
     Boise Holdings, Timber Holdings or any Restricted Subsidiary since the
     beginning of such period) shall have made any Asset Disposition, any
     Investment or acquisition of assets that would have required an adjustment
     pursuant to clause (3) or (4) above if made by Boise Holdings, Timber
     Holdings or a Restricted Subsidiary during such period, EBITDA and
     Consolidated Interest Expense for such period shall be calculated after
     giving PRO FORMA effect thereto as if such Asset Disposition, Investment or
     acquisition had occurred on the first day of such period;

          (6)    if since the beginning of such period any Person was designated
     as an Unrestricted Subsidiary or redesignated as or otherwise became a
     Restricted Subsidiary, EBITDA and Consolidated Interest Expense shall be
     calculated as if such event had occurred on the first day of such period;

          (7)    the EBITDA and Consolidated Interest Expense of discontinued
     operations recorded on or after the date such operations are classified as
     discontinued in accordance with GAAP shall be excluded; and

          (8)    for any four-quarter reference period that includes any period
     of time prior to the Acquisition, PRO FORMA effect shall be given for such
     period to the Acquisition and the other adjustments added to PRO FORMA
     EBITDA to calculate

<Page>

                                                                               8

     PRO FORMA Adjusted EBITDA as set forth in the Offering Memorandum in
     footnote 7 under "Offering memorandum summary--Summary historical and PRO
     FORMA condensed combined financial data" (without duplication of amounts
     otherwise included in the calculation of EBITDA), it being understood that,
     with respect to the adjustment related to the Additional Consideration
     Agreement, the adjustment shall be the amount set forth in the Offering
     Memorandum for calculating Adjusted EBITDA for the twelve months ended June
     30, 2004 until such time as the Measurement Period includes an actual
     payment or receipt pursuant to such agreement.

For purposes of this definition, whenever PRO FORMA effect is to be given to an
acquisition of assets, the amount of income or earnings relating thereto and the
amount of Consolidated Interest Expense associated with any Indebtedness
Incurred in connection therewith, the PRO FORMA calculations shall be determined
in good faith by a responsible financial or accounting Officer of Boise LLC and
may include Pro Forma Cost Savings. If any Indebtedness bears a floating rate of
interest and is being given PRO FORMA effect, the interest on such Indebtedness
shall be calculated as if the rate in effect on the date of determination had
been the applicable rate for the entire period (taking into account any Interest
Rate Agreement applicable to such Indebtedness if such Interest Rate Agreement
has a remaining term in excess of 12 months). For avoidance of doubt, in the
event the Timber Fall-away Date occurs during a Measurement Period, PRO FORMA
effect shall be given to such event as if it had occurred on the first day of
such period.

If any Indebtedness is Incurred under a revolving credit facility and is being
given PRO FORMA effect, the interest on such Indebtedness shall be calculated
based on the average daily balance of such Indebtedness for the four fiscal
quarters subject to the PRO FORMA calculation.

          "Consolidated Interest Expense" means, for any period, the total
interest expense of Boise Holdings, Timber Holdings and their consolidated
Restricted Subsidiaries on a Combined Consolidated Basis, plus, to the extent
not included in such total interest expense, and to the extent Incurred by Boise
Holdings, Timber Holdings or their Restricted Subsidiaries, without duplication:

          (1)    interest expense attributable to Capital Lease Obligations;

          (2)    amortization of debt discount and debt issuance cost (other
     than amortization of debt issuance costs in respect of Indebtedness
     Incurred in connection with the Acquisition);

          (3)    capitalized interest;

          (4)    non-cash interest expense;

          (5)    commissions, discounts and other fees and charges owed with

          (6)    net payments or receipts (if any) pursuant to Interest Rate
     Agreements;

     Issuer or Note Guarantor and all Preferred Stock of any Restricted
     Subsidiary that is not a Note Guarantor, in each case held by Persons other

     of Boise Holdings or Timber Holdings);

          (8)    interest Incurred in connection with Investments in
     discontinued operations;

          (9)    interest accruing on any Indebtedness of any Person (other than

     Subsidiaries) to the extent such Indebtedness is Guaranteed by (or secured
     by the assets of) such Person or any Restricted Subsidiary of such Person;
     and

          (10)   the cash contributions to any employee stock ownership plan or
     similar trust to the extent such contributions are used by such plan or
     trust to pay interest or fees to any Person (other than Boise Holdings,

                                 THE SECURITIES

          SECTION 2.01.     FORM AND DATING. Provisions relating to the Initial
Securities and the Exchange Securities are set forth in the Rule 144A/Regulation
S/IAI Appendix attached hereto (the "Appendix"), which is hereby incorporated
in, and expressly made part of, this Indenture. The Initial Securities and the
Trustee's certificate of authentication shall be substantially in the form of
Exhibit 1 or 2 to the Appendix, as the case may be, which are hereby
incorporated in, and expressly made a part of, this Indenture. The Exchange
Securities and the Trustee's certificate of authentication shall be
substantially in the form of Exhibit A or B hereto, as the case may be, which
are hereby incorporated in and expressly made a part of this Indenture. The
Securities may have notations, legends or endorsements required by law, stock
exchange rule, agreements to which the Issuers are subject, if any, or usage
(PROVIDED that any such notation, legend or endorsement is in a form acceptable
to the Issuers). Each Security shall be dated the date of its authentication.
The terms of the Securities set forth in the Appendix and Exhibits A and B are
part of the terms of this Indenture.

          SECTION 2.02.     EXECUTION AND AUTHENTICATION. Two Officers shall
sign the Securities for the Issuers by manual or facsimile signature. The
Issuers' seal shall be impressed, affixed, imprinted or reproduced on the
Securities and may be in facsimile form.

          If an Officer whose signature is on a Security no longer holds that
office at the time the Trustee authenticates the Security, the Security shall be
valid nevertheless.

          A Security shall not be valid until an authorized signatory of the
Trustee manually signs the certificate of authentication on the Security. The
signature shall be conclusive evidence that the Security has been authenticated
under this Indenture.

          On the Issue Date, the Trustee shall authenticate and deliver $250
million of Senior Notes and $400 million of Senior Subordinated Notes and, at
any time and from time to time thereafter, the Trustee shall authenticate and
deliver Securities for original issue in an aggregate principal amount specified
in a written order of the Issuers signed by two Officers or by an Officer and
either an Assistant Treasurer or an Assistant Secretary of the Issuers. Such
order shall specify the amount of the Securities to be authenticated and the
date on which the original issue of Securities is to be authenticated and, in
the case of an issuance of Additional Securities pursuant to Section 2.13 after
the Issue Date, shall certify that such issuance is in compliance with Section

          The Trustee may appoint an authenticating agent reasonably acceptable
to the Issuers to authenticate the Securities. Unless limited by the terms of
such

appointment, an authenticating agent may authenticate Securities whenever the
Trustee may do so. Each reference in this Indenture to authentication by the
Trustee includes authentication by such agent. An authenticating agent has the
same rights as any Registrar, Paying Agent or agent for service of notices and
demands.

          SECTION 2.03.     REGISTRAR AND PAYING AGENT. The Issuers shall
maintain an office or agency where Securities may be presented for registration
of transfer or for exchange (the "Registrar") and an office or agency where
Securities may be presented for payment (the "Paying Agent"). The Registrar
shall keep a register of each series of the Securities and of their transfer and
exchange. The Issuers may have one or more co-registrars and one or more
additional paying agents. The term "Paying Agent" includes any additional paying
agent.

          The Issuers shall enter into an appropriate agency agreement with any
Registrar, Paying Agent or co-registrar not a party to this Indenture, which
shall incorporate the terms of the TIA. The agreement shall implement the
provisions of this Indenture that relate to such agent. The Issuers shall notify
the Trustee of the name and address of any such agent. If the Issuers fail to
maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be
entitled to appropriate compensation therefor pursuant to Section 7.07. The
Issuers or any Wholly Owned Subsidiary of an Issuer incorporated or organized
within The United States of America may act as Paying Agent, Registrar,
co-registrar or transfer agent.

          The Issuers initially appoint the Trustee as Registrar and Paying
Agent in connection with each series of the Securities.

          SECTION 2.04.     PAYING AGENT TO HOLD MONEY IN TRUST. Prior to each
due date of the principal and interest on any Security, the Issuers shall
deposit with the Paying Agent a sum sufficient to pay such principal and
interest when so becoming due. The Issuers shall require each Paying Agent
(other than the Trustee) to agree in writing that the Paying Agent shall hold in
trust for the benefit of Securityholders of the Securities of a series or the
Trustee all money held by the Paying Agent for the payment of principal of or
interest on such series of Securities and shall notify the Trustee of any
default by the Issuers in making any such payment. If the Issuers or a
Subsidiary of an Issuer acts as Paying Agent, it shall segregate the money held
by it as Paying Agent and hold it as a separate trust fund. The Issuers at any
time may require a Paying Agent to pay all money held by it to the Trustee and
to account for any funds disbursed by the Paying Agent. Upon complying with this
Section, the Paying Agent shall have no further liability for the money
delivered to the Trustee.

          SECTION 2.05.     SECURITYHOLDER LISTS. The Trustee shall preserve in
as current a form as is reasonably practicable the most recent list available to
it of the names and addresses of Securityholders of each series of Securities.
If the Trustee is not the Registrar, the Issuers shall furnish to the Trustee,
in writing at least five Business Days before each interest payment date with
respect to a series of Securities and at such other times as the Trustee may
request in writing, a list in such form and as of such date

                                                                              46

as the Trustee may reasonably require of the names and addresses of
Securityholders of that series.

          SECTION 2.06.     TRANSFER AND EXCHANGE. The Securities shall be
issued in registered form and shall be transferable only upon the surrender of a
Security for registration of transfer. When a Security is presented to the
Registrar or a co-registrar with a request to register a transfer, the Registrar
shall register the transfer as requested if the requirements of this Indenture
and Section 8-401(1) of the Uniform Commercial Code are met. When Securities are
presented to the Registrar or a co-registrar with a request to exchange them for
an equal principal amount of Securities of other denominations of the same
series, the Registrar shall make the exchange as requested if the same
requirements are met.

          SECTION 2.07.     REPLACEMENT SECURITIES. If a mutilated Security is
surrendered to the Registrar or if the Holder of a Security claims that the
Security has been lost, destroyed or wrongfully taken, the Issuers shall issue
and the Trustee shall authenticate a replacement Security of the same series if
the requirements of Section 8-405 of the Uniform Commercial Code are met and the
Holder satisfies any other reasonable requirements of the Trustee. If required
by the Trustee or the Issuers, such Holder shall furnish an indemnity bond
sufficient in the judgment of the Issuers and the Trustee to protect the
Issuers, the Trustee, the Paying Agent, the Registrar and any co-registrar from
any loss which any of them may suffer if a Security is replaced. The Issuers and
the Trustee may charge the Holder for their expenses in replacing a Security.

          Every replacement Security is an additional Obligation of the Issuers.

          SECTION 2.08.     OUTSTANDING SECURITIES. Securities of a series
outstanding at any time are all Securities of such series authenticated by the
Trustee except for those canceled by it, those delivered to it for cancellation
and those described in this Section as not outstanding. A Security does not
cease to be outstanding because an Issuer or an Affiliate of an Issuer holds the
Security.

          If a Security is replaced pursuant to Section 2.07, it ceases to be
outstanding unless the Trustee and the Issuers receive proof satisfactory to
them that the replaced Security is held by a protected purchaser (as defined in
Section 8-303 of the Uniform Commercial Code).

          If the Paying Agent segregates and holds in trust, in accordance with
this Indenture, on a redemption date or maturity date money sufficient to pay
all principal and interest payable on that date with respect to the Securities
(or portions thereof) of a series to be redeemed or maturing, as the case may
be, and the Paying Agent is not prohibited from paying such money to the
Securityholders of such series on that date pursuant to the terms of this
Indenture, then on and after that date such Securities (or portions thereof)
cease to be outstanding and interest on them ceases to accrue.

          SECTION 2.09.     TEMPORARY SECURITIES. Until definitive Securities
are ready for delivery, the Issuers may prepare and the Trustee shall
authenticate

<Page>

                                                                              47

temporary Securities. Temporary Securities shall be substantially in the form of
definitive Securities but may have variations that the Issuers consider
appropriate for temporary Securities. Without unreasonable delay, the Issuers
shall prepare and the Trustee shall authenticate definitive Securities and
deliver them in exchange for temporary Securities.

          SECTION 2.10.     CANCELLATION. The Issuers at any time may deliver
Securities to the Trustee for cancellation. The Registrar and the Paying Agent
shall forward to the Trustee any Securities surrendered to them for registration
of transfer, exchange or payment. The Trustee and no one else shall cancel and
destroy (subject to the record retention requirements of the Exchange Act) all
Securities surrendered for registration of transfer, exchange, payment or
cancellation and deliver a certificate of such destruction to the Issuers unless
the Issuers direct the Trustee to deliver canceled Securities to the Issuers.
The Issuers may not issue new Securities to replace Securities it has redeemed,
paid or delivered to the Trustee for cancellation.

          SECTION 2.11.     DEFAULTED INTEREST. If the Issuers default in a
payment of interest on a series of the Securities, the Issuers shall pay
defaulted interest (plus interest on such defaulted interest to the extent
lawful) on such series in any lawful manner. The Issuers may pay the defaulted
interest on such series to the persons who are Securityholders of such series on
a subsequent special record date. The Issuers shall fix or cause to be fixed any
such special record date and payment date to the reasonable satisfaction of the
Trustee and shall promptly mail to each Securityholder of such series a notice
that states the special record date, the payment date and the amount of
defaulted interest to be paid.

          SECTION 2.12.     CUSIP NUMBERS, ISINS, ETC. The Issuers in issuing
the Securities may use "CUSIP" numbers, ISINs and "Common Code" numbers (in each
case if then generally in use) and, if so, the Trustee shall use "CUSIP"
numbers, ISINs and "Common Code" numbers in notices of redemption as a
convenience to Holders; PROVIDED, HOWEVER, that any such notice may state that
no representation is made as to the correctness of such numbers either as
printed on the Securities or as contained in any notice of a redemption and that
reliance may be placed only on the other identification numbers printed on the
Securities, and any such redemption shall not be affected by any defect in or
omission of such numbers. The Issuers shall advise the Trustee in writing of any
change in any "CUSIP" numbers, ISINs or "Common Code" numbers applicable to the
Securities.

          SECTION 2.13.     ISSUANCE OF ADDITIONAL SECURITIES. After the Issue
Date, the Issuers shall be entitled, subject to its compliance with Section
4.03, to issue Additional Securities of each series under this Indenture, which
Securities shall have identical terms as the Initial Securities of such series
issued on the Issue Date, other than with respect to the date of issuance and
issue price.

          With respect to any Additional Securities of a series, the Issuers
shall set forth in a resolution of the Board of Directors and an Officers'
Certificate, a copy of each which shall be delivered to the Trustee, the
following information:

     Securities;

          (2)    the series, the issue price, the issue date and the CUSIP
     number of such Additional Securities; PROVIDED, HOWEVER, that no Additional
     Securities may be issued at a price that would cause such Additional
     Securities to have "original issue discount" within the meaning of Section
     1273 of the Code; and

          (3)    whether such Additional Securities shall be Initial Securities
     or shall be issued in the form of Exchange Securities as set forth in
     Exhibit A or B, as the case may be.

          SECTION 2.14.     SERIES OF SECURITIES. All of the Senior Notes issued
under this Indenture (including any Additional Senior Notes) shall be treated as
a single class for all purposes of this Indenture, including waivers,
amendments, redemptions and offers to purchase. All of the Senior Subordinated
Notes issued under this Indenture (including any Additional Senior Subordinated
Notes) shall be treated as a single class for all purposes of this Indenture,
including waivers, amendments, redemptions and offers to purchase. The Senior
Notes and Senior Subordinated Notes shall be treated as separate classes for all
purposes of this Indenture, including waivers, amendments, redemptions, offers

          The Issuers shall give each notice to the Trustee provided for in this
Section at least 60 days before the redemption date unless the Trustee consents
to a shorter period. Such notice shall be accompanied by an Officers'
Certificate and an Opinion of Counsel from the Issuers to the effect that such
redemption will comply with the conditions herein.

          SECTION 3.02.     SELECTION OF SECURITIES TO BE REDEEMED. If fewer
than all the Securities of a series are to be redeemed, the Trustee shall select

not previously called for redemption. The Trustee may select for redemption
portions of the principal of Securities that have denominations larger than

principal amounts of $1,000 or a whole multiple of $1,000.

          (1)    any Indebtedness Incurred under the Credit Agreement on the
     Issue Date shall be treated as Incurred under clause (1) of paragraph (b)

     thereof) meets the criteria of more than one of the types of Indebtedness
     described above, the Issuers, in their sole discretion, shall classify such
     item of Indebtedness or any portion thereof at the time of Incurrence, and

respect to the Senior Subordinated Notes, neither the Issuers nor any Note
Guarantor shall Incur (1) any Indebtedness if such Indebtedness is subordinate
or junior in ranking in any respect to any Senior Indebtedness of such Issuer or
Note Guarantor, as applicable, unless such Indebtedness is Senior Subordinated

Subordinated Indebtedness of such Issuer or Note Guarantor, as applicable, or
(2) any Secured Indebtedness that is not Senior Indebtedness of such Person
unless contemporaneously therewith such Person makes effective provision to
secure the Senior Subordinated Notes or the relevant Note Guaranty of Senior
Subordinated Notes, as applicable, equally and ratably with (or on a senior

Senior Subordinated Notes or the relevant Note Guaranty of Senior Subordinated
Notes, as applicable) such Secured Indebtedness for so long as such Secured
Indebtedness is secured by a Lien.

          (f)    For purposes of determining compliance with any U.S. dollar

shall be the U.S. Dollar Equivalent determined on the date of the Incurrence of
such Indebtedness; PROVIDED, HOWEVER, that if any such Indebtedness denominated
in a

dollars covering all principal, premium, if any, and interest payable on such
Indebtedness, the amount of such Indebtedness expressed in U.S. dollars shall be
as provided in such Currency Agreement. The principal amount of any Refinancing
Indebtedness Incurred in the same currency as the Indebtedness being Refinanced
shall be the U.S. Dollar Equivalent of the Indebtedness Refinanced, except to
the extent that (1) such U.S. Dollar Equivalent was determined based on a
Currency Agreement, in which case the Refinancing Indebtedness shall be
determined in accordance with the preceding sentence, and (2) the principal
amount of the Refinancing Indebtedness exceeds the principal amount of the
Indebtedness being Refinanced, in which case the U.S. Dollar Equivalent of such
excess shall be determined on the date such Refinancing Indebtedness is
Incurred.

          (g)    For purposes of determining any particular amount of
Indebtedness under this Section 4.03, Guarantees, Liens or letter of credit
obligations supporting Indebtedness otherwise included in the determination of
such particular amount shall not be included so long as Incurred by a Person
that could have Incurred such Indebtedness pursuant to this Section 4.03.

          For the purposes of this Section 4.06(a), the following are deemed to
be cash or cash equivalents:

          (1)    the assumption or discharge of Indebtedness of Boise Holdings
     or Timber Holdings (other than obligations in respect of Disqualified Stock
     of Boise Holdings or Timber Holdings) or any Restricted Subsidiary (other
     than obligations in respect of Disqualified Stock or Preferred Stock of an
     Issuer or a Note Guarantor) and the release of Boise Holdings, Timber
     Holdings or such Restricted Subsidiary from all liability on such
     Indebtedness in connection with such Asset Disposition;

          (2)    securities received by Boise Holdings or Timber Holdings or any
     Restricted Subsidiary from the transferee that are converted within 90 days
     by Boise Holdings or Timber Holdings or such Restricted Subsidiary into
     cash, to the extent of cash received in that conversion; and

          (3)    any Designated Non-cash Consideration received by Boise
     Holdings, Timber Holdings or any Restricted Subsidiary in an Asset
     Disposition having an aggregate fair market value, taken together with all
     other Designated Non-cash Consideration received pursuant to this clause
     (3) (unless such Designated Non-cash Consideration has been converted into
     cash, which cash shall be treated after such conversion as Net Available
     Cash), not to exceed 5.0% of Total Assets at any time prior to the
     completion of the Timberlands Sales, and 7.5% of Total Assets thereafter,
     at the time of the receipt of such Designated Non-cash Consideration (with
     the fair market value of each item of Designated Non-cash Consideration
     being measured at the time received and without giving effect to subsequent
     changes in value).

          (b)    In the event of an Asset Disposition that requires the purchase
of Securities (and other Senior Indebtedness or Senior Subordinated
Indebtedness, as applicable, of Boise LLC) pursuant to Section 4.06 (a)(3)(C) ,
the Issuers shall purchase Securities tendered pursuant to an offer by the
Issuers for the Securities (and such other Senior Indebtedness or Senior
Subordinated Indebtedness, as applicable) (the "Offer") at a purchase price of
100% of their principal amount (or, in the event such other Senior Indebtedness
or Senior Subordinated Indebtedness, as applicable, of Boise LLC was issued with
significant original issue discount, 100% of the accreted value thereof) without
premium, plus accrued but unpaid interest (or, in respect of such other Senior
Indebtedness or Senior Subordinated Indebtedness, as applicable, of Boise LLC,
such lesser price, if any, as may be provided for by the terms of such
Indebtedness) in accordance with the procedures (including prorating in the
event of oversubscription) set forth in Section 4.06(c). If the aggregate
purchase price of the securities tendered exceeds the Net Available Cash
allotted to their purchase, the Issuers shall select the securities to be
purchased on a PRO RATA basis but in round denominations, which in the

case of the Securities shall be denominations of $1,000 principal amount or
multiples thereof. If the aggregate purchase price of the securities purchased
pursuant to such offer in accordance with this Section 4.06 is less than the Net
Available Cash offered therefor, the Issuers may use any such excess Net
Available Cash for general corporate purposes or any other purpose, in each case
not prohibited by this Indenture. The Issuers shall not be required to make such
an offer to purchase Securities (and other Senior Indebtedness or Senior
Subordinated Indebtedness, as applicable, of Boise LLC) pursuant to this Section
4.06 if the Net Available Cash available therefor is less than $20.0 million
(which lesser amount shall be carried forward for purposes of determining
whether such an Offer is required with respect to the Net Available Cash from
any subsequent Asset Disposition). Upon completion of such an Offer, Net
Available Cash shall be deemed to be reduced by the aggregate amount of such
Offer (regardless of the amount of Securities tendered in such offer).

          (c)    (1) Promptly, and in any event within 10 days after the Issuers
become obligated to make an Offer, the Issuers shall deliver to the Trustee and
send, by first-class mail to each Holder, a written notice stating that the
Holder may elect to have his Securities purchased by the Issuers either in whole
or in part (subject to prorating as described in Section 4.06(b) in the event
the Offer is oversubscribed) in integral multiples of $1,000 of principal
amount, at the applicable purchase price. The notice shall specify a purchase
date not less than 30 days nor more than 60 days after the date of such notice
(the "Purchase Date") and shall contain such information concerning the business
of Boise Holdings, Timber Holdings and the Restricted Subsidiaries which the
Issuers in good faith believe will enable such Holders to make an informed
decision and all instructions and materials necessary to tender Securities
pursuant to the Offer, together with the information contained in clause (3).

          (2)    Not later than the date upon which written notice of an Offer
     is delivered to the Trustee as provided below, the Issuers shall deliver to
     the Trustee an Officers' Certificate as to (A) the amount of the Offer (the
     "Offer Amount"), including information as to any other Senior Indebtedness
     or Senior Subordinated Indebtedness, as applicable, included in the Offer,
     (B) the allocation of the Net Available Cash from the Asset Dispositions
     pursuant to which such Offer is being made and (C) the compliance of such
     allocation with the provisions of Section 4.06(a) and (b). On such date,
     the Issuers shall also irrevocably deposit with the Trustee or with a
     Paying Agent (or, if an Issuer is acting as its own Paying Agent, segregate
     and hold in trust) in Temporary Cash Investments, maturing on the last day
     prior to the Purchase Date or on the Purchase Date if funds are immediately
     available by open of business, an amount equal to the Offer Amount to be
     held for payment in accordance with the provisions of this Section. If the
     Offer includes other Senior Indebtedness or Senior Subordinated
     Indebtedness, as applicable, the deposit described in the preceding
     sentence may be made with any other paying agent pursuant to arrangements
     satisfactory to the Trustee. Upon the expiration of the period for which
     the Offer remains open (the "Offer Period"), the Issuers shall deliver to
     the Trustee for cancellation the Securities or portions thereof which have
     been properly tendered to and are to be accepted by the Issuers. The
     Trustee shall, on the Purchase Date, mail or deliver

                                                                              71

     payment (or cause the delivery of payment) to each tendering Holder in the
     amount of the purchase price. In the event that the aggregate purchase
     price of the Securities delivered by the Issuers to the Trustee is less
     than the Offer Amount applicable to the Securities, the Trustee shall
     deliver the excess to the Issuers immediately after the expiration of the
     Offer Period for application in accordance with this Section 4.06.

          (3)    Holders electing to have a Security purchased shall be required
     to surrender the Security, with an appropriate form duly completed, to the
     Issuers at the address specified in the notice at least three Business Days
     prior to the Purchase Date. Holders shall be entitled to withdraw their
     election if the Trustee or an Issuer receives not later than one Business
     Day prior to the Purchase Date, a telex, facsimile transmission or letter
     setting forth the name of the Holder, the principal amount of the Security
     which was delivered for purchase by the Holder and a statement that such
     Holder is withdrawing his election to have such Security purchased. Holders
     whose Securities are purchased only in part shall be issued new Securities
     equal in principal amount to the unpurchased portion of the Securities
     surrendered.

          (4)    At the time the Issuers deliver Securities to the Trustee which
     are to be accepted for purchase, the Issuers shall also deliver an
     Officers' Certificate stating that such Securities are to be accepted by
     the Issuers pursuant to and in accordance with the terms of this Section
     4.06. A Security shall be deemed to have been accepted for purchase at the
     time the Trustee, directly or through an agent, mails or delivers payment
     therefor to the surrendering Holder.

          (d)    The Issuers will comply, to the extent applicable, with the
requirements of Section 14(e) of the Exchange Act and any other securities laws
or regulations in connection with the repurchase of Securities pursuant to this
Section 4.06. To the extent that the provisions of any securities laws or
regulations conflict with provisions of this Section 4.06, the Issuers shall
comply with the applicable securities laws and regulations and shall not be
deemed to have breached their obligations under this Section 4.06 by virtue of
their compliance with such securities laws or regulations.

          SECTION 4.07.     LIMITATION ON AFFILIATE TRANSACTIONS. (a) Boise
Holdings and Timber Holdings shall not, and shall not permit any of their
respective Restricted Subsidiaries to, enter into or permit to exist any
transaction (including the purchase, sale, lease or exchange of any property,
employee compensation arrangements or the rendering of any service) with, or for
the benefit of, any Affiliate of Boise Holdings or Timber Holdings (an
"Affiliate Transaction") unless:

          (1)    the terms of the Affiliate Transaction are no less favorable to
     Boise Holdings or Timber Holdings or such Restricted Subsidiary than those
     that could be obtained at the time of the Affiliate Transaction in
     arm's-length dealings with a Person who is not an Affiliate;

<Page>

                                                                              72

          (2)    if such Affiliate Transaction involves an amount in excess of
     $10.0 million, the terms of the Affiliate Transaction are set forth in
     writing and a majority of the directors of Boise Holdings or Timber
     Holdings, as the case may be (and, if any, a majority of the directors of
     Boise Holdings or Timber Holdings, as the case may be, disinterested with
     respect to such Affiliate Transaction), have determined in good faith that
     the criteria set forth in clause (1) are satisfied and have approved the
     relevant Affiliate Transaction as evidenced by a resolution of the Board of
     Directors; and

          (3)    if such Affiliate Transaction involves an amount in excess of
     $25.0 million, the Board of Directors of Boise Holdings or Timber Holdings,
     as the case may be, shall also have received a written opinion from an
     Independent Qualified Party to the effect that such Affiliate Transaction
     is fair, from a financial standpoint, to Boise Holdings or Timber Holdings,
     as the case may be, and its Restricted Subsidiaries or is not less
     favorable to Boise Holdings or Timber Holdings, as the case may be, and its
     Restricted Subsidiaries than could reasonably be expected to be obtained at
     the time in an arm's-length transaction with a Person who was not an
     Affiliate.

          (b)    The provisions of Section 4.07(a) shall not prohibit:

          (1)    any Permitted Investment or Restricted Payment, in each case
     permitted to be made pursuant to Section 4.04;

          (2)    any issuance of securities, or other payments, awards or grants
     in cash, securities or otherwise pursuant to, or the funding of, employment
     or compensation arrangements, stock options and stock ownership plans
     approved by the Board of Directors of Boise Holdings or Timber Holdings, as
     the case may be;

          (3)    the payment of reasonable fees to directors of Boise Holdings
     and Timber Holdings and their Restricted Subsidiaries or any direct or
     indirect parent of Boise Holdings or Timber Holdings who are not employees
     of Boise Holdings, Timber Holdings or their Restricted Subsidiaries and
     reasonable payments for indemnification to directors and officers of Boise
     Holdings or Timber Holdings and their respective Restricted Subsidiaries or
     any direct or indirect parent of Boise Holdings or Timber Holdings;

          (4)    any transaction with Boise Holdings, Timber Holdings, a
     Restricted Subsidiary or joint venture or similar entity which would
     constitute an Affiliate Transaction solely because Boise Holdings, Timber
     Holdings or a Restricted Subsidiary owns an equity interest in or otherwise
     controls such Restricted Subsidiary, joint venture or similar entity, or
     because of the common ownership of Boise Holdings and Timber Holdings by
     the Parent;

<Page>

                                                                              73

          (5)    the issuance or sale of any Capital Stock (other than
     Disqualified Stock) of Boise Holdings or Timber Holdings or any
     contribution to the capital of Boise Holdings or Timber Holdings;

          (6)    any agreement as in effect on the Issue Date and described in
     the Offering Memorandum under the heading "Certain relationships and
     related transactions" or "Management--Employment agreement" or any renewals
     or extensions of any such agreement (so long as such renewals or extensions
     are not, taken as a whole, materially less favorable to the Holders as
     determined by the Board of Directors of Boise LLC in its reasonable good
     faith judgment) and the transactions contemplated thereby;

          (7)    transactions with customers, clients, suppliers or purchasers
     or sellers of goods or services, in each case in the ordinary course of
     business and otherwise in compliance with the terms of this Indenture that
     are on terms no less favorable than those that would have been obtained in
     a comparable transaction with an unrelated party;

          (8)    any transaction effected as part of a Qualified Receivables
     Transaction;

          (9)    so long as no Default or Event of Default has occurred and is
     continuing, the payment of customary annual fees and related expenses to
     Madison Dearborn Partners, LLC and its Affiliates; PROVIDED that such fees
     shall not, in the aggregate, exceed $2.0 million (plus out-of-pocket

     or divestitures, in each case, which payments are (a) reasonably related to
     the services performed and (b) approved by a majority of the members of the
     Board of Directors of each of Boise Holdings and Timber Holdings not
     affiliated with Madison Dearborn Partners, LLC acting in good faith.

          SECTION 4.08.     LIMITATION ON LINE OF BUSINESS. Boise Holdings and

receive interest due on the relevant interest payment date), in accordance with
the terms contemplated in Section 4.09(b). In the event that at the time of such
Change of Control the terms of any Credit Agreement, in the case of the Senior
Notes, or the terms of any Senior Indebtedness of the Issuers (including any
Credit Agreement), in the case of the Senior Subordinated Notes, restrict or
prohibit the purchase of Securities following such Change of Control, then prior

consents under the agreements governing such Indebtedness to permit the
repurchase of the applicable series of Securities as provided in Section
4.09(b).

          (b)    Within 30 days following any Change of Control, the Issuers
shall mail a notice to each Holder with a copy to the Trustee (the "Change of

     date of purchase, plus accrued and unpaid interest, if any, to the date of
     purchase (subject to the right of Holders of record on the relevant record
     date to receive interest on the relevant interest payment date);

          (2)    the circumstances and relevant facts regarding such Change of
     Control (including information with respect to PRO FORMA historical income,

setting forth the name of the Holder, the principal amount of the Security which
was delivered for purchase by the Holder and a statement that such Holder is
withdrawing his election to have such Security purchased.

          (d)    On the purchase date, all Securities purchased by the Issuers

          (e)    Notwithstanding the foregoing provisions of this Section, the
Issuers shall not be required to make a Change of Control Offer with respect to
a series of Securities following a Change of Control if (1) a third party makes
the Change of Control Offer with respect to such series in the manner, at the
times and otherwise in compliance with the requirements set forth in this
Section applicable to a Change of Control Offer made by the Issuers and
purchases all Securities of such series validly tendered and not withdrawn under
such Change of Control Offer or (2) a notice of redemption of all of such series
of Securities has been given pursuant to this Indenture in accordance with
paragraph 5 of the Securities, unless and until there has been a default in
payment of the applicable redemption price. A Change of Control Offer may be
made in advance of a Change of Control, conditional upon the Change of Control,
if a definitive agreement is a place for the Change of Control at the time of
making of the Change of Control Offer.

          (f)    The Issuers shall comply, to the extent applicable, with the
requirements of Section 14(e) of the Exchange Act and any other securities laws

any of their respective Restricted Subsidiaries to, directly or indirectly,
Incur or permit to exist any Lien (the "Initial Lien") of any nature whatsoever
on any of their respective properties (including Capital Stock of a Restricted
Subsidiary), whether owned at the Issue Date or thereafter acquired, securing
any Indebtedness, other than Permitted Liens, without effectively providing that
the Senior Notes shall be secured equally and ratably with (or prior to) the
obligations so secured for so long as such obligations are so secured.

          Any Lien created for the benefit of the Holders of the Senior Notes
pursuant to the preceding sentence shall provide by its terms that such Lien
shall be automatically and unconditionally released and discharged upon the
release and discharge of the Initial Lien.

          SECTION 4.11      LIMITATION ON SALE/LEASEBACK TRANSACTIONS. Solely

     would be entitled to (A) Incur Indebtedness in an amount equal to the
     Attributable Debt with respect to such Sale/Leaseback Transaction pursuant
     to Section 4.03 and (B) create a Lien on such property securing such
     Attributable Debt without equally and ratably securing the Senior Notes

          (2)    the consideration received by Boise Holdings, Timber Holdings
     or any Restricted Subsidiary in connection with such Sale/Leaseback
     Transaction are at least equal to the fair market value (as determined by
     the Board of Directors of Boise Holdings or Timber Holdings if such fair
     market value exceeds $10,000,000, or an Officer of Boise Holdings or Timber
     Holdings, as the case may be, if such fair market value is equal to or less
     than $10,000,000) of such property; and

          (3)    the Net Available Cash from such transaction is applied in
     compliance with Section 4.06.

          SECTION 4.12      FUTURE GUARANTORS. At any time that any Indebtedness

that enters into a Guarantee of any Senior Indebtedness in a principal amount
outstanding in excess of $25.0 million (other than a Foreign Subsidiary that
Guarantees Senior Indebtedness Incurred by another Foreign Subsidiary) to, in
each case, within five Business Days of such Incurrence, execute and deliver to
the Trustee a Guaranty Agreement pursuant to which such Restricted Subsidiary
shall Guarantee payment of the Securities on the same terms and conditions as
those set forth in this Indenture. Notwithstanding the foregoing, this Section

          SECTION 4.15      FURTHER INSTRUMENTS AND ACTS. Upon request of the
Trustee, the Issuers shall execute and deliver such further instruments and do
such further acts as may be reasonably necessary or proper to carry out more

context otherwise requires, on and after the Timber Fall-away Date, the

Combined Consolidated Basis, to, any Person, unless:

          (1)    the resulting, surviving or transferee Person (the "Successor
     Company") shall be a Person organized and existing under the laws of the
     United States of America, any State thereof or the District of Columbia and
     the Successor Company (if not Boise Holdings, Timber Holdings, Boise LLC or
     Boise Finance, as applicable) shall expressly assume, by an indenture
     supplemental thereto, executed and delivered to the Trustee, in form
     satisfactory to the Trustee, all the obligations of Boise Holdings, Timber
     Holdings, Boise LLC or Boise Finance, as applicable, under the Note
     Guaranties or the Securities, as applicable, and this Indenture;

          (2)    immediately after giving PRO FORMA effect to such transaction
     (and treating any Indebtedness which becomes an obligation of the Successor
     Company or any Subsidiary as a result of such transaction as having been
     Incurred by such Successor Company or such Subsidiary at the time of such
     transaction), no Default shall have occurred and be continuing;

          (3)    immediately after giving PRO FORMA effect to such transaction,
     either (A) the Successor Company would be able to Incur an additional $1.00
     of

                                                                              78

     Indebtedness pursuant to Section 4.03(a) or (B) the Consolidated Coverage
     Ratio for the Successor Company would be greater than the Consolidated
     Coverage Ratio immediately prior to such transaction;

          (4)    the Issuers shall have delivered to the Trustee an Officers'
     Certificate and an Opinion of Counsel, each stating that such
     consolidation, merger or transfer and such supplemental indenture (if any)
     comply with this Indenture; and

          (5)    the Issuers shall have delivered to the Trustee an Opinion of
     Counsel to the effect that the Holders will not recognize income, gain or
     loss for Federal income tax purposes as a result of such transaction and
     will be subject to Federal income tax on the same amounts, in the same
     manner and at the same times as would have been the case if such
     transaction had not occurred.

PROVIDED, HOWEVER, that clause (3) shall not be applicable to (A) Timber
Holdings or any Restricted Subsidiary consolidating with, merging into or
transferring all or part of its properties and assets to Boise Holdings, Timber
Holdings or a Wholly Owned Subsidiary (so long as no Capital Stock of Boise

Person) or (B) Boise Holdings, Timber Holdings, Boise Finance or Boise LLC
merging with an Affiliate of Boise LLC solely for the purpose and with the sole
effect of reincorporating Boise Holdings, Timber Holdings, Boise Finance or
Boise LLC in another jurisdiction.

          For purposes of this Section 5.01, (A) the sale, lease, conveyance,
assignment, transfer or other disposition of all or substantially all of the
properties and assets of one or more Subsidiaries of Boise Holdings, Timber
Holdings or Boise LLC, which properties and assets, if held by Boise Holdings,
Timber Holdings or Boise LLC, as applicable, instead of such Subsidiaries, would
constitute all or substantially all of the properties and assets of Boise
Holdings, Timber Holdings and the Restricted Subsidiaries determined on a
Combined Consolidated Basis, shall be deemed to be the transfer of all or
substantially all of the properties and assets of Boise Holdings, Timber
Holdings and the Restricted Subsidiaries and (B) a disposition of all or
substantially all of the Timberlands Assets or of the Capital Stock of a Person
that together with its Subsidiaries does not own or control material assets or
operations other than Timberlands Assets shall not be deemed to be a sale of all
or substantially all of the assets of Boise Holdings, Timber Holdings and the
Restricted Subsidiaries determined on a Combined Consolidated Basis; PROVIDED
that the disposition referred to in this clause (B) is made in compliance with
Section 4.06.

          The Successor Company shall be the successor to Boise Holdings, Timber
Holdings, Boise LLC or Boise Finance, as applicable, and shall succeed to, and

          (1)    Timber Holdings, the Subsidiary Guarantor or Cross Guarantor
     (A) has been disposed of in its entirety to another Person (other than to
     Boise Holdings, Timber Holdings or an Affiliate of Boise Holdings or Timber

     or assets or (B) as a result of the disposition of all or a portion of its
     Capital Stock, has ceased to be a Subsidiary of Timber Holdings or Boise
     Holdings, as applicable (or, in the case of Timber Holdings, has ceased to
     be a Subsidiary of Parent), in both cases, if in connection therewith the
     Issuers provide an Officers' Certificate to the Trustee to the effect that
     Boise Holdings or Timber Holdings, as the case may be, shall comply with
     its obligations under Section 4.06 in respect of such disposition; or

          (2)    the resulting, surviving or transferee Person (if not such Note
     Guarantor) shall be a Person organized and existing under the laws of the
     jurisdiction under which such Note Guarantor was organized or under the
     laws of the United States of America, or any State thereof or the District
     of Columbia, (B) such Person shall expressly assume, by a Guaranty
     Agreement, in a form satisfactory to the Trustee, all the obligations of
     such Note Guarantor, if any, under its Note Guaranties; (C) immediately
     after giving effect to such transaction or transactions on a PRO FORMA
     basis (and treating any Indebtedness which becomes an obligation of the
     resulting, surviving or transferee Person as a result of such transaction
     as having been issued by such Person at the time of such transaction), no
     Default shall have occurred and be continuing; and (D) the Issuers deliver
     to the Trustee an Officers' Certificate and an Opinion of Counsel, each
     stating that such consolidation, merger or transfer and such Guaranty
     Agreement, if any, comply with this Indenture;

PROVIDED, HOWEVER, that this Section 5.01 shall not be applicable to any
Subsidiary Guarantor or Cross Guarantor consolidating with, merging into or
transferring all or part of its properties and assets to any Issuer or Note
Guarantor where an Issuer or Note Guarantor is the surviving Person.

          in an involuntary case;

          any substantial part of its property; or

          The foregoing shall constitute Events of Default whatever the reason

effected by operation of law or pursuant to any judgment, decree or order of any
court or any order, rule or regulation of any administrative or governmental
body.

means any receiver, trustee, assignee, liquidator, custodian or similar official
under any Bankruptcy Law.

          A Default under clauses (4) and (5) shall not constitute an Event of
Default with respect to a series of Securities until the Trustee or the Holders
of at least 25% in principal amount of the outstanding Securities of such series
notify the Issuers of the Default and the Issuers do not cure such Default
within the time specified after receipt of such notice. Such notice must specify
the Default, demand that it be remedied and state that such notice is a "Notice
of Default".

<Page>

                                                                              82

          The Issuers shall deliver to the Trustee, within 30 days after the
occurrence thereof, written notice in the form of an Officers' Certificate of
any Event of Default under clause (6), (9) or (10) and any event which with the
giving of notice or the lapse of time would become an Event of Default under
clause (4), (5) or (9), its status and what action the Issuers are taking or
propose to take with respect thereto.

          SECTION 6.02      ACCELERATION. (a) If an Event of Default (other than
an Event of Default specified in Section 6.01(7) or (8) with respect to an
Issuer, Boise Holdings or, prior to the Timber Fall-away Date, Timber Holdings)
with respect to a series of Securities occurs and is continuing, the Trustee, by
notice to the Issuers, or the Holders of at least 25% in principal amount of the
outstanding Securities of such series, by notice to the Issuers and the Trustee,
may declare the principal of and accrued but unpaid interest on all the
Securities of such series to be due and payable. Upon such a declaration of
acceleration, such principal and interest shall be due and payable immediately.
If an Event of Default specified in Section 6.01(7) or (8) with respect to an
Issuer, Boise Holdings or, prior to the Timber Fall-away Date, Timber Holdings,
occurs, the principal of and interest on all the Securities shall IPSO FACTO
become and be immediately due and payable without any declaration or other act
on the part of the Trustee or any Holders of the Securities. The Holders of a
majority in principal amount of the Securities of a series by notice to the
Trustee may rescind an acceleration and its consequences with respect to such
series if the rescission would not conflict with any judgment or decree and if
all existing Events of Default with respect to that series have been cured or
waived except nonpayment of principal or interest that has become due solely
because of acceleration. No such rescission shall affect any subsequent Default
with respect to such series or impair any right consequent thereto.

          (b)    In the event of a declaration of acceleration of a series of
Securities because an Event of Default has occurred and is continuing as a
result of the acceleration of any Indebtedness described in Section 6.01(6)
(excluding any resulting payment default under this Indenture or such series of
Securities), the declaration of acceleration of such series of the Securities
shall be automatically annulled if the holders of all Indebtedness described in
Section 6.01(6) have rescinded the declaration of acceleration in respect of
such Indebtedness within 20 days of the date of such declaration, and if the
annulment of the acceleration of such series of Securities would not conflict
with any judgment or decree of a court of competent jurisdiction, and all
existing Events of Default with respect to such series, except non-payment of
principal or interest on such series of Securities that became due solely
because of the acceleration of such series of Securities, have been cured or
waived.

          SECTION 6.03      OTHER REMEDIES. If an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy to collect the payment
of principal of or interest on the Securities of each series to which an Event
of Default applies or to enforce the performance of any provision of such
Securities or this Indenture.

          The Trustee may maintain a proceeding even if it does not possess any
of the Securities or does not produce any of them in the proceeding. A delay or
omission by

                                                                              83

the Trustee or any Securityholder in exercising any right or remedy accruing
upon an Event of Default shall not impair the right or remedy or constitute a
waiver of or acquiescence in the Event of Default. No remedy is exclusive of any
other remedy. All available remedies are cumulative.

          SECTION 6.04      WAIVER OF PAST DEFAULTS. The Holders of a majority
in aggregate principal amount of the Securities of a series then outstanding by
notice to the Trustee may on behalf of the Holders of all of the Securities of
such series waive an existing Default or Event of Default and its consequences
under this Indenture with respect to such series except (i) a continuing Default
or Event of Default in the payment of interest on, or the principal of, a
Security of such series, (ii) a Default arising from the failure to redeem or
purchase any Securities of such series when required pursuant to this Indenture
or (iii) a Default in respect of a provision that under Section 9.02 cannot be
amended without the consent of each Holder affected. When a Default is waived
with respect to a series of Securities, it is deemed cured with respect to such
series, but no such waiver shall extend to any subsequent or other Default or
impair any consequent right.

          SECTION 6.05      CONTROL BY MAJORITY. The Holders of a majority in
principal amount of the Securities of a series may direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee or of
exercising any trust or power conferred on the Trustee with respect to such
series. However, the Trustee may refuse to follow any direction that conflicts
with law or this Indenture or, subject to Section 7.01, that the Trustee
determines is unduly prejudicial to the rights of other Securityholders of such
series or would involve the Trustee in personal liability; PROVIDED, HOWEVER,
that the Trustee may take any other action deemed proper by the Trustee that is
not inconsistent with such direction. Prior to taking any action under this
Article 6, the Trustee shall be entitled to indemnification satisfactory to it
in its sole discretion against all losses and expenses caused by taking or not
taking such action.

          SECTION 6.06      LIMITATION ON SUITS. Except to enforce the right to
receive payment of principal, premium (if any) or interest when due, no
Securityholder may pursue any remedy with respect to this Indenture or the
Securities of a series unless:

          (1)    such Holder gives to the Trustee written notice that an Event
     of Default with respect to such series is continuing;

          (2)    the Holders of at least 25% in principal amount of the
     outstanding Securities of that series make a written request to the Trustee
     to pursue the remedy;

          (3)    such Holder or Holders offer to the Trustee reasonable security
     or indemnity against any loss, liability or expense;

          (4)    the Trustee does not comply with such request within 60 days
     after the receipt thereof and the offer of security or indemnity; and

<Page>

                                                                              84

          (5)    Holders of a majority in principal amount of the outstanding
     Securities of that series do not give the Trustee a direction inconsistent
     with such request during such 60-day period.

          A Securityholder may not use this Indenture to prejudice the rights of
another Securityholder of the same series or to obtain a preference or priority
over another Securityholder of the same series. In the event that the Definitive
Securities are not issued to any beneficial owner promptly after the Registrar
has received a request from the Holder of a Global Security to issue such
Definitive Securities to such beneficial owner or its nominee, the Issuers
expressly agree and acknowledge, with respect to the right of any Holder to
pursue a remedy pursuant to this Indenture, the right of such beneficial holder
of Securities to pursue such remedy with respect to the portion of the Global
Security that represents such beneficial holder's Securities as if such
Definitive Securities had been issued.

          SECTION 6.07      RIGHTS OF HOLDERS TO RECEIVE PAYMENT.
Notwithstanding any other provision of this Indenture, the right of any Holder
to receive payment of principal of and interest on the Securities held by such
Holder, on or after the respective due dates expressed in the Securities, or to
bring suit for the enforcement of any such payment on or after such respective
dates, shall not be impaired or affected without the consent of such Holder.

          SECTION 6.08      COLLECTION SUIT BY TRUSTEE. If an Event of Default
specified in Section 6.01(1) or (2) occurs and is continuing, the Trustee may
recover judgment in its own name and as trustee of an express trust against the
Issuers for the whole amount then due and owing (together with interest on any
unpaid interest to the extent lawful) and the amounts provided for in Section
7.07.

          SECTION 6.09      TRUSTEE MAY FILE PROOFS OF CLAIM. The Trustee may
file such proofs of claim and other papers or documents as may be necessary or
advisable in order to have the claims of the Trustee and the Securityholders
allowed in any judicial proceedings relative to the Issuers, their creditors or
their property and, unless prohibited by law or applicable regulations, may vote
on behalf of the Holders in any election of a trustee in bankruptcy or other
Person performing similar functions, and any Custodian in any such judicial
proceeding is hereby authorized by each Holder to make payments to the Trustee
and, in the event that the Trustee shall consent to the making of such payments
directly to the Holders, to pay to the Trustee any amount due it for the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and its counsel, and any other amounts due the Trustee under Section
7.07.

          SECTION 6.10      PRIORITIES. If the Trustee collects any money or
property with respect to a series of Securities pursuant to this Article 6, it
shall pay out the money or property in the following order:

          FIRST:       to the Trustee for amounts due under Section 7.07 with
     respect to such series;

<Page>

                                                                              85

          SECOND:      solely with respect to the Senior Subordinated Notes, to
     holders of Senior Indebtedness (including the Senior Notes) of the Issuers
     and, if such money or property has been collected from a Note Guarantor, to
     holders of Senior Indebtedness (including Guaranties of the Senior Notes)
     of such Note Guarantor, in each case to the extent required by Article 10
     and 12;

          THIRD:       to Holders of Securities of such series for amounts due
     and unpaid on such Securities for principal and interest, ratably, without
     preference or priority of any kind, according to the amounts due and
     payable on the Securities of such series for principal and interest,
     respectively; and

          FOURTH:      to the Issuers.

          The Trustee may fix a record date and payment date for any payment to
Securityholders pursuant to this Section. At least 15 days before such record
date, the Issuers shall mail to each Securityholder and the Trustee a notice
that states the record date, the payment date and amount to be paid.

          SECTION 6.11      UNDERTAKING FOR COSTS. In any suit for the
enforcement of any right or remedy under this Indenture or in any suit against
the Trustee for any action taken or omitted by it as Trustee, a court in its
discretion may require the filing by any party litigant in the suit of an
undertaking to pay the costs of the suit, and the court in its discretion may
assess reasonable costs, including reasonable attorneys' fees, against any party
litigant in the suit, having due regard to the merits and good faith of the
claims or defenses made by the party litigant. This Section does not apply to a
suit by the Trustee, a suit by a Holder pursuant to Section 6.07 or a suit by
Holders of more than 10% in aggregate principal amount of the Securities of a
series.

          SECTION 6.12      WAIVER OF STAY OR EXTENSION LAWS. The Issuers (to
the extent they may lawfully do so) shall not at any time insist upon, or plead,
or in any manner whatsoever claim or take the benefit or advantage of, any stay
or extension law wherever enacted, now or at any time hereafter in force, which
may affect the covenants or the performance of this Indenture; and the Issuers
(to the extent that they may lawfully do so) hereby expressly waive all benefit
or advantage of any such law, and shall not hinder, delay or impede the
execution of any power herein granted to the Trustee, but shall suffer and
permit the execution of every such power as though no such law had been enacted.

                                    Article 7

                                     TRUSTEE

          SECTION 7.01      DUTIES OF TRUSTEE. (a) If an Event of Default has
occurred and is continuing, the Trustee shall exercise the rights and powers
vested in it by this Indenture and use the same degree of care and skill in
their exercise as a prudent Person would exercise or use under the circumstances
in the conduct of such Person's own affairs.

                                                                              86

          (b)    Except during the continuance of an Event of Default:

          (1)    the Trustee undertakes to perform such duties and only such
     duties as are specifically set forth in this Indenture and no implied
     covenants or obligations shall be read into this Indenture against the
     Trustee; and

          (2)    in the absence of bad faith on its part, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness of
     the opinions expressed therein, upon certificates or opinions furnished to
     the Trustee and conforming to the requirements of this Indenture. However,
     the Trustee shall examine the certificates and opinions to determine
     whether or not they conform to the requirements of this Indenture.

          (c)    The Trustee may not be relieved from liability for its own
negligent action, its own negligent failure to act or its own wilful misconduct,
except that:

          (1)    this paragraph does not limit the effect of paragraph (b) of
     this Section;

          (2)    the Trustee shall not be liable for any error of judgment made
     in good faith by a Trust Officer unless it is proved that the Trustee was
     negligent in ascertaining the pertinent facts; and

          (3)    the Trustee shall not be liable with respect to any action it
     takes or omits to take in good faith in accordance with a direction
     received by it pursuant to Section 6.05.

expend or risk its own funds or otherwise incur financial liability in the
performance of any of its duties hereunder or in the exercise of any of its
rights or powers, if it shall have reasonable grounds to believe that repayment
of such funds or adequate indemnity against such risk or liability is not
reasonably assured to it.

          (h)    Every provision of this Indenture relating to the conduct or
affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Section and to the provisions of the TIA.

          SECTION 7.02      RIGHTS OF TRUSTEE. (a) The Trustee may rely on any
document believed by it to be genuine and to have been signed or presented by
the proper person. The Trustee need not investigate any fact or matter stated in
the document.

          (b)    Before the Trustee acts or refrains from acting, it may require

for the misconduct or negligence of any agent appointed with due care.

          (d)    The Trustee shall not be liable for any action it takes or

rights or powers; PROVIDED, HOWEVER, that the Trustee's conduct does not
constitute wilful misconduct or negligence.

          (e)    The Trustee may consult with counsel, and the advice or opinion
of counsel with respect to legal matters relating to this Indenture and the
Securities shall be full and complete authorization and protection from
liability in respect to any action taken, omitted or suffered by it hereunder in
good faith and in accordance with the advice or opinion of such counsel.

          SECTION 7.03      INDIVIDUAL RIGHTS OF TRUSTEE. The Trustee in its
individual or any other capacity may become the owner or pledgee of Securities
and may otherwise deal with the Issuers or their Affiliates with the same rights
it would have if it were not Trustee. Any Paying Agent, Registrar, co-registrar
or co-paying agent may do the same with like rights. However, the Trustee must
comply with Sections 7.10 and 7.11.

          SECTION 7.04      TRUSTEE'S DISCLAIMER. The Trustee shall not be
responsible for and makes no representation as to the validity or adequacy of
this Indenture or the Securities, it shall not be accountable for the Issuers'
use of the proceeds from the Securities, and it shall not be responsible for any
statement of the Issuers in this Indenture or in any document issued in
connection with the sale of the Securities or in the Securities other than the
Trustee's certificate of authentication. The Trustee shall have no
responsibility or liability with respect to any information, statement or
recital in any offering memorandum or other disclosure material prepared or
distributed with respect to the issuance of the Securities. The Issuers shall
not be deemed agents of the Trustee, Registrar or Paying Agent for any purpose,
and the Trustee, Registrar and Paying Agent shall not be responsible for the
compliance of any of them with their respective duties hereunder in connection
with the transactions contemplated herein.

          SECTION 7.05      NOTICE OF DEFAULTS. If a Default occurs, is
continuing and is known to the Trustee, the Trustee shall mail to each
Securityholder of each series of Securities to which such Default applies notice
of the Default within 90 days after it occurs. Except in the case of a Default
in the payment of principal of or

                                                                              88

interest on any Security, the Trustee may withhold the notice if and so long as
a committee of its Trust Officers in good faith determines that withholding the
notice is not opposed to the interests of the Securityholders.

          SECTION 7.06      REPORTS BY TRUSTEE TO HOLDERS. As promptly as
practicable after each October 15 beginning with the October 15 following the
date of this Indenture, and in any event prior to December 15 in each year, the
Trustee shall mail to each Securityholder a brief report dated as of October 15
that complies with TIA Section 313(a). The Trustee also shall comply with TIA
Section 313(b).

          A copy of each report at the time of its mailing to Securityholders of
a series shall be filed with the SEC and each stock exchange (if any) on which
the Securities of that series are listed. The Issuers agree to notify promptly
the Trustee whenever the Securities of either series become listed on any stock
exchange and of any delisting thereof.

          SECTION 7.07      COMPENSATION AND INDEMNITY. The Issuers shall pay to
the Trustee from time to time reasonable compensation for its services. The
Trustee's compensation shall not be limited by any law on compensation of a
trustee of an express trust. The Issuers shall reimburse the Trustee upon
request for all reasonable out-of-pocket expenses incurred or made by it,
including costs of collection, in addition to the compensation for its services.
Such expenses shall include the reasonable compensation and expenses,
disbursements and advances of the Trustee's agents, counsel, accountants and
experts. The Issuers shall indemnify the Trustee against any and all loss,
liability or expense (including attorneys' fees) incurred by it in connection
with the administration of this trust and the performance of its duties
hereunder. The Trustee shall notify the Issuers promptly of any claim for which
it may seek indemnity. Failure by the Trustee to so notify the Issuers shall not
relieve the Issuers of their obligations hereunder. The Issuers shall defend the
claim and the Trustee may have separate counsel and the Issuers shall pay the
fees and expenses of such counsel. The Issuers need not reimburse any expense or
indemnify against any loss, liability or expense incurred by the Trustee through
the Trustee's own willful misconduct, negligence or bad faith.

          To secure the Issuers' payment obligations in this Section, the
Trustee shall have a lien prior to the Securities on all money or property held
or collected by the Trustee other than money or property held in trust to pay
principal of and interest on particular Securities.

          The Issuers' payment obligations pursuant to this Section shall
survive the discharge of this Indenture. When the Trustee incurs expenses after
the occurrence of a Default specified in Section 6.01(7) or (8) with respect to
an Issuer, the expenses are intended to constitute expenses of administration
under the Bankruptcy Law.

          SECTION 7.08      REPLACEMENT OF TRUSTEE. The Trustee may resign at
any time with respect to a series of Securities by so notifying the Issuers. The
Holders of a majority in principal amount of the Securities of a series may
remove the Trustee with

<Page>

                                                                              89

respect to such series by so notifying the Trustee and may appoint a successor
Trustee with respect to such series. The Issuers shall remove the Trustee if:

          (1)    the Trustee fails to comply with Section 7.10;

          (2)    the Trustee is adjudged bankrupt or insolvent;

          (3)    a receiver or other public officer takes charge of the Trustee
     or its property; or

          (4)    the Trustee otherwise becomes incapable of acting.

          If the Trustee resigns, is removed by the Issuers or by the Holders of
a majority in principal amount of the Securities of a series with respect to
such series, and such Holders do not reasonably promptly appoint a successor
Trustee with respect to such series, or if a vacancy exists in the office of
Trustee with respect to a series of Securities for any reason (the Trustee in
such event being referred to herein as the retiring Trustee), the Issuers shall
promptly appoint a successor Trustee.

          A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Issuers. Thereupon the
resignation or removal of the retiring Trustee with respect to the applicable
series of Securities shall become effective, and the successor Trustee shall
have all the rights, powers and duties of the Trustee under this Indenture with
respect to the applicable series of Securities. The successor Trustee shall mail
a notice of its succession to Securityholders of such series of Securities. The
retiring Trustee shall promptly transfer all property held by it as Trustee in
respect of the applicable series of Securities to the successor Trustee of such
series, subject to the lien provided for in Section 7.07.

          If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee or the Holders of
10% in principal amount of the applicable series of Securities may petition any
court of competent jurisdiction for the appointment of a successor Trustee for
such series of Securities.

          If the Trustee fails to comply with Section 7.10, any Securityholder
of a series of Securities may petition any court of competent jurisdiction for
the removal of the Trustee with respect to such series and the appointment of a
successor Trustee with respect to such series.

          Notwithstanding the replacement of the Trustee pursuant to this
Section, the Issuers' obligations under Section 7.07 shall continue for the
benefit of the retiring Trustee.

          SECTION 7.09      SUCCESSOR TRUSTEE BY MERGER. If the Trustee
consolidates with, merges or converts into, or transfers all or substantially
all its corporate trust business or assets to, another corporation or banking
association, the resulting, surviving or transferee corporation without any
further act shall be the successor Trustee.

                                                                              90

          In case at the time such successor or successors by merger, conversion
or consolidation to the Trustee shall succeed to the trusts created by this
Indenture any of the Securities shall have been authenticated but not delivered,
any such successor to the Trustee may adopt the certificate of authentication of
any predecessor trustee, and deliver such Securities so authenticated; and in
case at that time any of the Securities shall not have been authenticated, any
successor to the Trustee may authenticate such Securities either in the name of
any predecessor hereunder or in the name of the successor to the Trustee; and in
all such cases such certificates shall have the full force which it is anywhere
in the Securities or in this Indenture provided that the certificate of the
Trustee shall have.

          SECTION 7.10      ELIGIBILITY; DISQUALIFICATION. The Trustee shall at
all times satisfy the requirements of TIA Section 310(a). The Trustee shall have
a combined capital and surplus of at least $50,000,000 as set forth in its most
recent published annual report of condition. The Trustee shall comply with TIA
Section 310(b); PROVIDED, HOWEVER, that there shall be excluded from the
operation of TIA Section 310(b)(1) any indenture or indentures under which other
securities or certificates of interest or participation in other securities of
the Issuers are outstanding if the requirements for such exclusion set forth in
TIA Section 310(b)(1) are met.

          SECTION 7.11      PREFERENTIAL COLLECTION OF CLAIMS AGAINST ISSUERS.
The Trustee shall comply with TIA Section 311(a), excluding any creditor
relationship listed in TIA Section 311(b). A Trustee who has resigned or been
removed shall be subject to TIA Section 311(a) to the extent indicated.

                                    Article 8

                       DISCHARGE OF INDENTURE; DEFEASANCE

          SECTION 8.01      DISCHARGE OF LIABILITY ON SECURITIES; DEFEASANCE.
(a) When (1) the Issuers deliver to the Trustee all outstanding Securities of a
series (other than Securities replaced pursuant to Section 2.07) for
cancellation or (2) all outstanding Securities of a series have become due and
payable, whether at maturity or on a redemption date as a result of the mailing
of a notice of redemption pursuant to Article 3 hereof, and, in the case of
clause (2), the Issuers irrevocably deposit with the Trustee funds sufficient to
pay at maturity or upon redemption all outstanding Securities of such series,
including interest thereon to maturity or such redemption date (other than
Securities replaced pursuant to Section 2.07), and if in either case the Issuers
pay all other sums payable hereunder by the Issuers with respect to such series,
then this Indenture shall, subject to Section 8.01(c), cease to be of further
effect with respect to such series. The Trustee shall acknowledge satisfaction
and discharge of this Indenture with respect to such series on demand of the
Issuers accompanied by an Officers' Certificate and an Opinion of Counsel and at
the cost and expense of the Issuers.

          (b)    Subject to Sections 8.01(c) and 8.02, the Issuers at any time
may terminate (1) all their obligations under the Senior Subordinated Notes and
this Indenture with respect to the Senior Subordinated Notes ("legal defeasance
option") or (2) their

<Page>

                                                                              91

obligations under Sections 4.02, 4.03, 4.04, 4.05, 4.06, 4.07, 4.08, 4.09, 4.12
and 4.13 and the operation of Sections 6.01(4), 6.01(6), 6.01(7), 6.01(8) and
6.01(9) (but, in the case of Sections 6.01(7) and (8), with respect only to
Significant Subsidiaries and Note Guarantors (other than Boise Holdings and
Timber Holdings)) and the limitations contained in Section 5.01(a)(3) ("covenant
defeasance option"), in each case, with respect to the Senior Subordinated
Notes. The Issuers may exercise their legal defeasance option notwithstanding
their prior exercise of their covenant defeasance option.

          If the Issuers exercise their legal defeasance option, payment of the
Senior Subordinated Notes may not be accelerated because of an Event of Default
with respect thereto. If the Issuers exercise their covenant defeasance option,
payment of the Senior Subordinated Notes may not be accelerated because of an
Event of Default specified in Sections 6.01(4), 6.01(6), 6.01(7), 6.01(8) or
6.01(9) (but, in the case of Sections 6.01(7) and (8), with respect only to
Significant Subsidiaries) or because of the failure of an Issuer, Boise Holdings
or Timber Holdings to comply with Section 5.01(a)(3). If the Issuers exercise
their legal defeasance option or their covenant defeasance option, each Note
Guarantor, if any, shall be released from all its obligations with respect to
its Guaranty of the Senior Subordinated Notes.

          Upon satisfaction of the conditions set forth herein and upon request
of the Issuers, the Trustee shall acknowledge in writing the discharge of those
obligations that the Issuers terminate.

          (c)    Notwithstanding clauses (a) and (b) above, the Issuers'
obligations with respect to the Senior Subordinated Notes in Sections 2.03,
2.04, 2.05, 2.06, 2.07, 2.08, 7.07 and 7.08 and in this Article 8 shall survive
until the Senior Subordinated Notes have been paid in full. Thereafter, the
Issuers' obligations in Sections 7.07, 8.04 and 8.05 shall survive.

          SECTION 8.02      CONDITIONS TO DEFEASANCE. The Issuers may exercise
their legal defeasance option or their covenant defeasance option only if:

          (1)    the Issuers irrevocably deposit in trust with the Trustee money
     or U.S. Government Obligations for the payment of principal of and interest
     on the Senior Subordinated Notes to maturity or redemption, as the case may
     be;

          (2)    the Issuers deliver to the Trustee a certificate from a
     nationally recognized firm of independent accountants expressing their
     opinion that the payments of principal and interest when due and without
     reinvestment on the deposited U.S. Government Obligations plus any
     deposited money without investment will provide cash at such times and in
     such amounts as will be sufficient to pay principal and interest when due
     on all the Senior Subordinated Notes to maturity or redemption, as the case
     may be;

          (3)    123 days pass after the deposit is made and during the 123-day
     period no Default specified in Sections 6.01(7) or (8) with respect to the
     Issuers occurs which is continuing at the end of the period;

<Page>

                                                                              92

          (4)    the deposit does not constitute a default under any other
     agreement binding on the Issuers and is not prohibited by Article 10;

          (5)    the Issuers deliver to the Trustee an Opinion of Counsel to the
     effect that the trust resulting from the deposit does not constitute, or is
     qualified as, a regulated investment company under the Investment Company
     Act of 1940;

          (6)    in the case of the legal defeasance option, the Issuers shall
     have delivered to the Trustee an Opinion of Counsel stating that (A) the
     Issuers have received from, or there has been published by, the Internal
     Revenue Service a ruling, or (B) since the date of this Indenture there has
     been a change in the applicable Federal income tax law, in either case to
     the effect that, and based thereon such Opinion of Counsel shall confirm
     that, the Holders of the Senior Subordinated Notes will not recognize
     income, gain or loss for Federal income tax purposes as a result of such
     defeasance and will be subject to Federal income tax on the same amounts,
     in the same manner and at the same times as would have been the case if
     such defeasance had not occurred;

          (7)    in the case of the covenant defeasance option, the Issuers
     shall have delivered to the Trustee an Opinion of Counsel to the effect
     that the Holders of the Senior Subordinated Notes will not recognize
     income, gain or loss for Federal income tax purposes as a result of such
     covenant defeasance and will be subject to Federal income tax on the same
     amounts, in the same manner and at the same times as would have been the
     case if such covenant defeasance had not occurred; and

          (8)    the Issuers deliver to the Trustee an Officers' Certificate and
     an Opinion of Counsel, each stating that all conditions precedent to the
     defeasance and discharge of the Senior Subordinated Notes as contemplated
     by this Article 8 have been complied with.

          Before or after a deposit, the Issuers may make arrangements
satisfactory to the Trustee for the redemption of Senior Subordinated Notes at a
future date in accordance with Article 3.

          SECTION 8.03      APPLICATION OF TRUST MONEY. The Trustee shall hold
in trust money or U.S. Government Obligations deposited with it pursuant to this
Article 8. It shall apply the deposited money and the money from U.S. Government
Obligations through the Paying Agent and in accordance with this Indenture to
the payment of principal of and interest on the Senior Subordinated Notes. Money
and securities so held in trust are not subject to Article 10.

          SECTION 8.04      REPAYMENT TO ISSUERS. The Trustee and the Paying
Agent shall promptly turn over to the Issuers upon request any excess money or
securities held by them at any time.

<Page>

                                                                              93

          Subject to any applicable abandoned property law, the Trustee and the
Paying Agent shall pay to the Issuers upon request any money held by them for
the payment of principal or interest that remains unclaimed for two years, and,
thereafter, Securityholders entitled to the money must look to the Issuers for
payment as general creditors.

          SECTION 8.05      INDEMNITY FOR GOVERNMENT OBLIGATIONS. The Issuers
shall pay and shall indemnify the Trustee against any tax, fee or other charge
imposed on or assessed against deposited U.S. Government Obligations or the
principal and interest received on such U.S. Government Obligations.

          SECTION 8.06      REINSTATEMENT. If the Trustee or Paying Agent is
unable to apply any money or U.S. Government Obligations in accordance with this
Article 8 by reason of any legal proceeding or by reason of any order or
judgment of any court or governmental authority enjoining, restraining or
otherwise prohibiting such application, the Issuers' and each Note Guarantor's
obligations under this Indenture with respect to the Senior Subordinated Notes,
each Note Guaranty of the Senior Subordinated Notes and the Senior Subordinated
Notes shall be revived and reinstated as though no deposit had occurred pursuant
to this Article 8 until such time as the Trustee or Paying Agent is permitted to
apply all such money or U.S. Government Obligations in accordance with this
Article 8; PROVIDED, HOWEVER, that, if the Issuers have made any payment of
interest on or principal of any Senior Subordinated Notes because of the
reinstatement of their obligations, the Issuers shall be subrogated to the
rights of the Holders of such Senior Subordinated Notes to receive such payment
from the money or U.S. Government Obligations held by the Trustee or Paying
Agent.

                                   AMENDMENTS

          SECTION 9.01      WITHOUT CONSENT OF HOLDERS. The Issuers, the Note
Guarantors and the Trustee may amend this Indenture with respect to a series of
Securities or the Securities of that series without notice to or consent of any
Holder of Securities of that series:

          (1)    to cure any ambiguity, omission, defect or inconsistency
     (including conforming this Indenture to the description contained in the
     Offering Memorandum under the heading "Description of notes");

          (2)    to provide for the assumption by a successor corporation of the
     obligations of an Issuer or any Note Guarantor under this Indenture to
     comply with Article 5;

          (3)    to provide for uncertificated Securities in addition to or in
     place of certificated Securities of that series (PROVIDED that the
     uncertificated Securities are issued in registered form for purposes of
     Section 163(f) of the Code, or in a

<Page>

                                                                              94

     manner such that the uncertificated Securities are described in Section
     163(f)(2)(B) of the Code);

          (4)    to add Guarantees with respect to the Securities of that
     series, including any Subsidiary or Cross Guaranties, or to secure the
     Securities of that series;

          (5)    to add to the covenants of the Issuers or a Note Guarantor for
     the benefit of the Holders of the Securities of that series or to surrender
     any right or power herein conferred upon the Issuers or a Note Guarantor
     with respect to that series;

          (6)    to make any change that does not adversely affect the rights of
     any Holder of the Securities of that series;

          (7)    to comply with any requirement of the SEC in connection with
     qualifying or maintaining the qualification of this Indenture under the
     TIA; or

          (8)    to make any amendment to the provisions of this Indenture
     relating to the transfer and legending of Securities; PROVIDED, HOWEVER,
     that (a) compliance with this Indenture as so amended would not result in
     Securities being transferred in violation of the Securities Act or any
     other applicable securities law and (b) such amendment does not materially
     and adversely affect the rights of Holders to transfer Securities.

          An amendment under this Section with respect to the Senior
Subordinated Notes may not make any change that adversely affects the rights
under Article 10 or 12 of any holder of Senior Indebtedness (including the
Senior Notes and the Note Guaranties in respect of the Senior Notes) of an
Issuer or of a Note Guarantor then outstanding unless the holders of such Senior
Indebtedness (or their Representative) consent to such change.

          After an amendment under this Section becomes effective, the Issuers
shall mail to the Securityholders of the applicable series of Securities a
notice briefly describing such amendment. The failure to give such notice to all
Securityholders, or any defect therein, shall not impair or affect the validity
of an amendment under this Section.

          SECTION 9.02      WITH CONSENT OF HOLDERS. The Issuers, the Note
Guarantors and the Trustee may amend this Indenture with respect to the
Securities of a series or such Securities with the written consent of the
Holders of at least a majority in principal amount of the Securities of that
series then outstanding (including consents obtained in connection with a tender
offer or exchange for such Securities) and any past default or compliance with
any provisions with respect to the Securities of a series may also be waived
with the consent of the Holders of at least a majority in principal amount of
the Securities of that series then outstanding. However, without the consent of
each Holder of an outstanding Security of a series affected thereby, an
amendment or waiver may not, with respect to that series:

<Page>

                                                                              95

          (1)    reduce the amount of such Securities whose Holders must consent
     to an amendment;

          (2)    reduce the rate of or extend the time for payment of interest
     on any such Security;

          (3)    reduce the principal of or change the Stated Maturity of any
     such Security;

          (4)    change the provisions applicable to the redemption of any such
     Security as described under Article 3 hereof or paragraph 5 of such
     Security;

          (5)    make any such Security payable in money other than that stated
     in the Security;

          (6)    impair the right of any Holder of such Securities to receive
     payment of principal of and interest on such Holder's Securities of such
     series on or after the due dates therefor or to institute suit for the
     enforcement of any payment on or with respect to such Holder's Securities
     of such series;

          (7)    make any change in the amendment provisions which require each
     Holder's consent or in the waiver provisions;

          (8)    make any change in the ranking or priority of any such Security
     that would adversely affect the Holders of that series of Securities; or

          (9)    make any change in, or release other than in accordance with
     this Indenture, any Note Guaranty that would adversely affect the Holders
     of that series of Securities.

          It shall not be necessary for the consent of the Holders under this
Section to approve the particular form of any proposed amendment, but it shall
be sufficient if such consent approves the substance thereof.

          An amendment under this Section with respect to the Senior
Subordinated Notes may not make any change that adversely affects the rights
under Article 10 or 12 of any holder of Senior Indebtedness (including the
Senior Notes and the Note Guaranties in respect of the Senior Notes) of an
Issuer or of a Note Guarantor then outstanding unless the holders of such Senior
Indebtedness (or their Representative) consent to such change

          After an amendment under this Section becomes effective, the Issuers
shall mail to Securityholders of the applicable series a notice briefly
describing such amendment. The failure to give such notice to all
Securityholders, or any defect therein, shall not impair or affect the validity
of an amendment under this Section.

          SECTION 9.03      COMPLIANCE WITH TRUST INDENTURE ACT. Every amendment
to this Indenture or the Securities shall comply with the TIA as then in effect.

<Page>

                                                                              96

          SECTION 9.04      REVOCATION AND EFFECT OF CONSENTS AND WAIVERS. (a) A
consent to an amendment or a waiver by a Holder of a Security shall bind the
Holder and every subsequent Holder of that Security or portion of the Security
that evidences the same debt as the consenting Holder's Security, even if
notation of the consent or waiver is not made on the Security. However, any such
Holder or subsequent Holder may revoke the consent or waiver as to such Holder's
Security or portion of the Security if the Trustee receives the notice of
revocation before the date the amendment or waiver becomes effective. After an
amendment or waiver with respect to a series of Securities becomes effective, it
shall bind every Securityholder of such series. An amendment or waiver becomes
effective upon the execution of such amendment or waiver by the Trustee.

          (b)    The Issuers may, but shall not be obligated to, fix a record
date for the purpose of determining the Securityholders entitled to give their
consent or take any other action described above or required or permitted to be
taken pursuant to this Indenture. If a record date is fixed, then
notwithstanding the immediately preceding paragraph, those Persons who were
Securityholders at such record date (or their duly designated proxies), and only
those Persons, shall be entitled to give such consent or to revoke any consent
previously given or to take any such action, whether or not such Persons
continue to be Holders after such record date. No such consent shall be valid or
effective for more than 120 days after such record date.

          SECTION 9.05      NOTATION ON OR EXCHANGE OF SECURITIES. If an
amendment changes the terms of a Security, the Trustee may require the Holder of
the Security to deliver it to the Trustee. The Trustee may place an appropriate
notation on the Security regarding the changed terms and return it to the
Holder. Alternatively, if the Issuers so determine or the Trustee so determines,
the Issuers in exchange for the Security shall issue and the Trustee shall
authenticate a new Security of the same series that reflects the changed terms.
Failure to make the appropriate notation or to issue a new Security shall not
affect the validity of such amendment.

          SECTION 9.06      TRUSTEE TO SIGN AMENDMENTS. The Trustee shall sign
any amendment authorized pursuant to this Article 9 if the amendment does not
adversely affect the rights, duties, liabilities or immunities of the Trustee.
If it does, the Trustee may but need not sign it. In signing such amendment the
Trustee shall be entitled to receive indemnity reasonably satisfactory to it and
to receive, and (subject to Section 7.01) shall be fully protected in relying
upon, an Officers' Certificate and an Opinion of Counsel stating that such
amendment is authorized or permitted by this Indenture.

          SECTION 9.07      PAYMENT FOR CONSENT. Neither the Issuers nor any
Affiliate of the Issuers shall, directly or indirectly, pay or cause to be paid
any consideration, whether by way of interest, fee or otherwise, to any Holder
of a series of Securities for or as an inducement to any consent, waiver or
amendment of any of the terms or provisions of this Indenture with respect to
such series of Securities or such Securities unless such consideration is
offered to all Holders of such series of Securities and is paid to all Holders
of such series of Securities that so consent, waive or agree to

                                                                              97

amend in the time frame set forth in solicitation documents relating to such
consent, waiver or agreement.

                                   Article 10

                                  SUBORDINATION

          SECTION 10.01     AGREEMENT TO SUBORDINATE. Each of the Issuers
agrees, and each Holder of a Senior Subordinated Note by accepting a Senior
Subordinated Note agrees, that the Indebtedness evidenced by the Senior
Subordinated Notes is subordinated in right of payment, to the extent and in the
manner provided in this Article 10, to the prior payment of all Senior
Indebtedness of the Issuers (including the Senior Notes) and that the
subordination is for the benefit of and enforceable by the holders of such
Senior Indebtedness. The Senior Subordinated Notes shall in all respects rank
PARI PASSU with all other Senior Subordinated Indebtedness of the Issuers and
only Indebtedness of the Issuers which is Senior Indebtedness shall rank senior
to the Senior Subordinated Notes in accordance with the provisions set forth
herein. All provisions of this Article 10 shall be subject to Section 10.12.

          SECTION 10.02     LIQUIDATION, DISSOLUTION, BANKRUPTCY. Upon any
payment or distribution of the assets of an Issuer to creditors upon a total or
partial liquidation or a total or partial dissolution of an Issuer or in a
bankruptcy, reorganization, insolvency, receivership or similar proceeding
relating to an Issuer or its property:

          (1)    holders of Senior Indebtedness of Boise LLC or Boise Finance,
     as the case may be, shall be entitled to receive payment in full in cash of
     such Senior Indebtedness before Holders of Senior Subordinated Notes shall
     be entitled to receive any payment of principal of or interest on the
     Senior Subordinated Notes; and

          (2)    until the Senior Indebtedness of Boise LLC or Boise Finance, as
     the case may be, is paid in full in cash, any payment or distribution to
     which Holders of Senior Subordinated Notes would be entitled but for this
     Article 10 shall be made to holders of such Senior Indebtedness as their
     interests may appear, except that Holders of Senior Subordinated Notes may
     receive shares of stock and any debt securities that are subordinated to
     such Senior Indebtedness to at least the same extent as the Senior
     Subordinated Notes.

          SECTION 10.03     DEFAULT ON SENIOR INDEBTEDNESS OF THE ISSUERS. (a)
The Issuers shall not pay the principal of, premium, if any, or interest on the
Senior Subordinated Notes or make any deposit pursuant to Section 8.01 and may
not purchase, redeem or otherwise retire any Senior Subordinated Notes
(collectively, "pay the Senior Subordinated Notes") if either of the following
(a "Payment Default") occurs:

          (1)    any Obligation on any Designated Senior Indebtedness of the
     Issuers is not paid in full in cash when due; or

<Page>

                                                                              98

          (2)    any other default on Designated Senior Indebtedness of the
     Issuers occurs and the maturity of such Designated Senior Indebtedness is
     accelerated in accordance with its terms;

unless, in either case, the Payment Default has been cured or waived and any
such acceleration has been rescinded or such Designated Senior Indebtedness has
been paid in full in cash; PROVIDED, HOWEVER, that the Issuers shall be entitled
to pay the Senior Subordinated Notes without regard to the foregoing if the
Issuers and the Trustee receive written notice approving such payment from the
Representatives of all Designated Senior Indebtedness with respect to which the
Payment Default has occurred and is continuing.

          (b)    During the continuance of any default (other than a Payment
Default) with respect to any Designated Senior Indebtedness of the Issuers
pursuant to which the maturity thereof may be accelerated without further notice
(except such notice as may be required to effect such acceleration) or the
expiration of any applicable grace periods, the Issuers shall not pay the Senior
Subordinated Notes for a period (a "Payment Blockage Period") commencing upon
the receipt by the Trustee (with a copy to the Issuers) of written notice (a
"Blockage Notice") of such default from the Representative of such Designated
Senior Indebtedness specifying an election to effect a Payment Blockage Period
and ending 179 days thereafter. The Payment Blockage Period shall end earlier if
such Payment Blockage Period is terminated:

          (1)    by written notice to the Trustee and the Issuers from the
     Person or Persons who gave such Blockage Notice;

          (2)    because the default giving rise to such Blockage Notice, and
     all other defaults on such Designated Senior Indebtedness, if any, are
     cured, waived or otherwise no longer continuing; or

          (3)    because such Designated Senior Indebtedness has been discharged
     or repaid in full in cash.

Notwithstanding the provisions described in the immediately preceding two
sentences (but subject to the provisions contained in the first sentence of this
Section), unless the holders of such Designated Senior Indebtedness or the
Representative of such Designated Senior Indebtedness shall have accelerated the
maturity of such Designated Senior Indebtedness, the Issuers shall be entitled
to resume paying the Senior Subordinated Notes after termination of such Payment
Blockage Period. The Senior Subordinated Notes shall not be subject to more than
one Payment Blockage Period in any consecutive 360-day period irrespective of
the number of defaults with respect to Designated Senior Indebtedness of the
Issuers during such period; PROVIDED, HOWEVER, that if any Blockage Notice
within such 360-day period is delivered to the Trustee by or on behalf of
holders of Designated Senior Indebtedness of the Issuers (other than holders of
Indebtedness under any Credit Agreement), the Representative of the holders of
Indebtedness under any Credit Agreement shall be entitled to give another
Blockage Notice within such period; PROVIDED FURTHER, HOWEVER, that in no event
shall the total number of days during which any Payment Blockage Period or
Periods is in effect exceed 179 days in the

<Page>

                                                                              99

aggregate during any consecutive 360-day period, and there must be 181 days
during any consecutive 360-day period during which no Payment Blockage Period is
in effect.

          SECTION 10.04     ACCELERATION OF PAYMENT OF SECURITIES. If payment of
the Senior Subordinated Notes is accelerated because of an Event of Default, the
Issuers or the Trustee shall promptly notify the holders of the Designated
Senior Indebtedness of the Issuers (or their Representatives) of the
acceleration. If any Designated Senior Indebtedness of the Issuers is
outstanding, neither the Issuers nor any Note Guarantor shall pay the Senior
Subordinated Notes until five Business Days after the Representatives of all the
issues of Designated Senior Indebtedness of the Issuers receive notice of such
acceleration and, thereafter, shall be entitled to pay the Senior Subordinated
Notes only if this Article 10 otherwise permits payment at that time.

          SECTION 10.05     WHEN DISTRIBUTION MUST BE PAID OVER. If a
distribution is made to Holders of Senior Subordinated Notes that because of
this Article 10 should not have been made to them, such Holders of the Senior
Subordinated Notes who receive such distribution shall hold such distribution in
trust for the holders of Senior Indebtedness of Boise LLC or Boise Finance, as
the case may be, and pay it over to them as their interests may appear.

          SECTION 10.06     SUBROGATION. After all Senior Indebtedness of the
Issuers is paid in full and until the Senior Subordinated Notes are paid in
full, Holders of Senior Subordinated Notes shall be subrogated to the rights of
holders of such Senior Indebtedness to receive distributions applicable to such
Senior Indebtedness. A distribution made under this Article 10 to holders of
such Senior Indebtedness which otherwise would have been made to Holders of
Senior Subordinated Notes is not, as between the Issuers and the Holders of
Senior Subordinated Notes, a payment by the Issuers on such Senior Indebtedness.

          SECTION 10.07     RELATIVE RIGHTS. This Article 10 defines the
relative rights of Holders of Senior Subordinated Notes and holders of Senior
Indebtedness of the Issuers. Nothing in this Indenture shall:

          (1)    impair, as between the Issuers and Holders of Senior
     Subordinated Notes, the obligation of the Issuers, which is absolute and
     unconditional, to pay principal of and interest on the Senior Subordinated
     Notes in accordance with their terms; or

          (2)    prevent the Trustee or any Holder of Senior Subordinated Notes
     from exercising its available remedies upon a Default, subject to the
     rights of holders of Senior Indebtedness of the Issuers to receive
     distributions otherwise payable to Holders of Senior Subordinated Notes.

          SECTION 10.08     SUBORDINATION MAY NOT BE IMPAIRED BY ISSUERS. No
right of any holder of Senior Indebtedness of the Issuers to enforce the
subordination of the Indebtedness evidenced by the Senior Subordinated Notes
shall be impaired by any

<Page>

                                                                             100

act or failure to act by either of the Issuers or by the failure of either
Issuer to comply with this Indenture.

          SECTION 10.09     RIGHTS OF TRUSTEE AND PAYING AGENT. Notwithstanding
Section 10.03, the Trustee or Paying Agent shall continue to make payments on
the Senior Subordinated Notes and shall not be charged with knowledge of the
existence of facts that under this Article 10 would prohibit the making of any
such payments unless, not less than two Business Days prior to the date of such
payment, a Trust Officer of the Trustee receives notice satisfactory to it that
such payments are prohibited by this Article 10. The Issuers, the Registrar or
co-registrar, the Paying Agent, a Representative or a holder of Senior
Indebtedness of the Issuers shall be entitled to give the notice; PROVIDED,
HOWEVER, that, if an issue of Senior Indebtedness of the Issuers has a
Representative, only the Representative shall be entitled to give the notice.

          The Trustee in its individual or any other capacity shall be entitled
to hold Senior Indebtedness of the Issuers with the same rights it would have if
it were not Trustee. The Registrar and co-registrar and the Paying Agent shall
be entitled to do the same with like rights. The Trustee shall be entitled to
all the rights set forth in this Article 10 with respect to any Senior
Indebtedness of the Issuers which may at any time be held by it, to the same
extent as any other holder of such Senior Indebtedness; and nothing in Article 7
shall deprive the Trustee of any of its rights as such holder. Nothing in this
Article 10 shall apply to claims of, or payments to, the Trustee under or
pursuant to Section 7.07.

          SECTION 10.10     DISTRIBUTION OR NOTICE TO REPRESENTATIVE. Whenever
any Person is to make a distribution or give a notice to holders of Senior
Indebtedness of the Issuers, such Person shall be entitled to make such
distribution or give such notice to their Representative (if any).

          SECTION 10.11     NOT TO PREVENT EVENTS OF DEFAULT OR LIMIT RIGHT TO
ACCELERATE. The failure to make a payment pursuant to the Senior Subordinated
Notes by reason of any provision in this Article 10 shall not be construed as
preventing the occurrence of a Default. Nothing in this Article 10 shall have
any effect on the right of the Holders of Senior Subordinated Notes or the
Trustee to accelerate the maturity of the Senior Subordinated Notes.

          SECTION 10.12     TRUST MONEYS NOT SUBORDINATED. Notwithstanding
anything contained herein to the contrary, payments from money or the proceeds
of U.S. Government Obligations held in trust under Article 8 by the Trustee for
the payment of principal of and interest on the Senior Subordinated Notes shall
not be subordinated to the prior payment of any Senior Indebtedness of the
Issuers or subject to the restrictions set forth in this Article 10, and none of
the Holders of Senior Subordinated Notes shall be obligated to pay over any such
amount to the Issuers or any holder of Senior Indebtedness of the Issuers or any
other creditor of the Issuers.

          SECTION 10.13     TRUSTEE ENTITLED TO RELY. Upon any payment or
distribution pursuant to this Article 10, the Trustee and the Holders of Senior

<Page>

                                                                             101

Subordinated Notes shall be entitled to rely (a) upon any order or decree of a
court of competent jurisdiction in which any proceedings of the nature referred
to in Section 10.02 are pending, (b) upon a certificate of the liquidating
trustee or agent or other Person making such payment or distribution to the
Trustee or to the Holders of Senior Subordinated Notes or (c) upon the
Representatives of Senior Indebtedness of the Issuers for the purpose of
ascertaining the Persons entitled to participate in such payment or
distribution, the holders of such Senior Indebtedness and other Indebtedness of
the Issuers, the amount thereof or payable thereon, the amount or amounts paid
or distributed thereon and all other facts pertinent thereto or to this Article
10. In the event that the Trustee determines, in good faith, that evidence is
required with respect to the right of any Person as a holder of Senior
Indebtedness of the Issuers to participate in any payment or distribution
pursuant to this Article 10, the Trustee shall be entitled to request such
Person to furnish evidence to the reasonable satisfaction of the Trustee as to
the amount of such Senior Indebtedness held by such Person, the extent to which
such Person is entitled to participate in such payment or distribution and other
facts pertinent to the rights of such Person under this Article 10, and, if such
evidence is not furnished, the Trustee shall be entitled to defer any payment to
such Person pending judicial determination as to the right of such Person to
receive such payment. The provisions of Sections 7.01 and 7.02 shall be
applicable to all actions or omissions of actions by the Trustee pursuant to
this Article 10.

          SECTION 10.14     TRUSTEE TO EFFECTUATE SUBORDINATION. Each Holder of
Senior Subordinated Notes by accepting a Senior Subordinated Note authorizes and
directs the Trustee on his behalf to take such action as may be necessary or
appropriate to acknowledge or effectuate the subordination between the Holders
of Senior Subordinated Notes and the holders of Senior Indebtedness of the
Issuers as provided in this Article 10 and appoints the Trustee as
attorney-in-fact for any and all such purposes.

          SECTION 10.15     TRUSTEE NOT FIDUCIARY FOR HOLDERS OF SENIOR
INDEBTEDNESS OF THE ISSUERS. The Trustee shall not be deemed to owe any
fiduciary duty to the holders of Senior Indebtedness of the Issuers pursuant to
this Article 10 and shall not be liable to any such holders if it shall
mistakenly pay over or distribute to Holders of Senior Subordinated Notes or the
Issuers or any other Person, money or assets to which any holders of Senior
Indebtedness of the Issuers shall be entitled by virtue of this Article 10.

          SECTION 10.16     RELIANCE BY HOLDERS OF SENIOR INDEBTEDNESS OF THE
ISSUERS ON SUBORDINATION PROVISIONS. Each Holder of Senior Subordinated Notes by
accepting a Senior Subordinated Note acknowledges and agrees that the foregoing
subordination provisions are, and are intended to be, an inducement and a
consideration to each holder of any Senior Indebtedness of the Issuers, whether
such Senior Indebtedness was created or acquired before or after the issuance of
the Senior Subordinated Notes, to acquire and continue to hold, or to continue
to hold, such Senior Indebtedness and such holder of such Senior Indebtedness
shall be deemed conclusively to have relied on such subordination provisions in
acquiring and continuing to hold, or in continuing to hold, such Senior
Indebtedness.

                                   Article 11

                                 NOTE GUARANTIES

          SECTION 11.01     GUARANTIES. (a) Each Note Guarantor of a series of
Securities hereby unconditionally and irrevocably guarantees, jointly and
severally, to each Holder of such series of Securities and to the Trustee and
its successors and assigns (a) the full and punctual payment of principal of and
interest on the Securities of such series when due, whether at maturity, by
acceleration, by redemption or otherwise, and all other monetary obligations of
the Issuers under this Indenture with respect to such series of Securities and
such Securities and (b) the full and punctual performance within applicable
grace periods of all other obligations of the Issuers under this Indenture with
respect to such series of Securities and such Securities (all the foregoing
being hereinafter collectively called the "Guaranteed Obligations" with respect
to a series of Securities). Each Note Guarantor further agrees that the
Guaranteed Obligations may be extended or renewed, in whole or in part, without
notice or further assent from such Note Guarantor and that such Note Guarantor
shall remain bound under this Article 11 notwithstanding any extension or
renewal of any Obligation.

          (b)    Each Note Guarantor of a series of Securities waives
presentation to, demand of, payment from and protest to the Issuers of any of
the Guaranteed Obligations in respect of such series of Securities and also
waives notice of protest for nonpayment. Each Note Guarantor of a series of
Securities waives notice of any default under the Securities of such series or
the Guaranteed Obligations in respect of such series of Securities. The
obligations of each Note Guarantor with respect to a series of Securities
hereunder shall not be affected by (1) the failure of any Holder or the Trustee
to assert any claim or demand or to enforce any right or remedy against the
Issuers or any other Person (including any Note Guarantor) under this Indenture
in respect of such series of Securities, such Securities or any other agreement
or otherwise; (2) any extension or renewal of any thereof; (3) any rescission,
waiver, amendment or modification of any of the terms or provisions of this
Indenture in respect of such series of Securities, such Securities or any other
agreement; (4) the release of any security held by any Holder or the Trustee for
the Guaranteed Obligations in respect of such series of Securities or any of
them; (5) the failure of any Holder or the Trustee to exercise any right or
remedy against any other guarantor of the Guaranteed Obligations in respect of
such series of Securities; or (6) except as set forth in Section 11.06, any
change in the ownership of such Note Guarantor.

          Each Note Guarantor further agrees that its Note Guaranty in respect
of a series of Securities herein constitutes a guarantee of payment, performance
and compliance when due (and not a guarantee of collection) and waives any right
to require that any resort be had by any Holder or the Trustee to any security
held for payment of the Guaranteed Obligations in respect of such series of
Securities.

          (c)    Each Note Guaranty in respect of the Senior Subordinated Notes
is, to the extent and in the manner set forth in Article 12, subordinated and
subject in right of payment to the prior payment in full of the principal of and
premium, if any, and

<Page>

                                                                             103

interest on all Senior Indebtedness (including the Note Guaranties in respect of
the Senior Notes) of the Note Guarantor giving such Note Guaranty and each such
Note Guaranty is made subject to such provisions of this Indenture.

          (d)    Except as expressly set forth in Sections 8.01(b), 11.02 and
11.06, the obligations of each Note Guarantor in respect of a series of
Securities hereunder shall not be subject to any reduction, limitation,
impairment or termination for any reason, including any claim of waiver,
release, surrender, alteration or compromise, and shall not be subject to any
defense of setoff, counterclaim, recoupment or termination whatsoever or by
reason of the invalidity, illegality or unenforceability of the Guaranteed
Obligations in respect of such series of Securities or otherwise. Without
limiting the generality of the foregoing, the obligations of each Note Guarantor
in respect of a series of Securities herein shall not be discharged or impaired
or otherwise affected by the failure of any Holder or the Trustee to assert any
claim or demand or to enforce any remedy under this Indenture in respect of such
series of Securities, such Securities or any other agreement, by any waiver or
modification of any thereof, by any default, failure or delay, willful or
otherwise, in the performance of the Guaranteed Obligations in respect of such
series of Securities, or by any other act or thing or omission or delay to do
any other act or thing which may or might in any manner or to any extent vary
the risk of such Note Guarantor or would otherwise operate as a discharge of
such Note Guarantor as a matter of law or equity.

          (e)    Each Note Guarantor further agrees that its Guarantee in
respect of a series of Securities herein shall continue to be effective or be
reinstated, as the case may be, if at any time payment, or any part thereof, of
principal of or interest on any Guaranteed Obligation in respect of such series
of Securities is rescinded or must otherwise be restored by any Holder or the
Trustee upon the bankruptcy or reorganization of the Issuers or otherwise.

          (f)    In furtherance of the foregoing and not in limitation of any
other right which any Holder or the Trustee has at law or in equity against any
Note Guarantor by virtue hereof, upon the failure of the Issuers to pay the
principal of or interest on any Guaranteed Obligation in respect of a series of
Securities when and as the same shall become due, whether at maturity, by
acceleration, by redemption or otherwise, or to perform or comply with any other
Guaranteed Obligation in respect of such series of Securities, each Note
Guarantor hereby promises to and shall, upon receipt of written demand by the
Trustee, forthwith pay, or cause to be paid, in cash, to the Holders or the
Trustee an amount equal to the sum of (A) the unpaid amount of such Guaranteed
Obligations in respect of such series of Securities, (B) accrued and unpaid
interest on such Guaranteed Obligations (but only to the extent not prohibited
by law) and (C) all other monetary Guaranteed Obligations of the Issuers to the
Holders of such series of Securities and the Trustee.

          (g)    Each Note Guarantor of a series of Securities agrees that it
shall not be entitled to any right of subrogation in respect of any Obligations
in respect of such series of Securities guaranteed hereby until payment in full
of all Guaranteed Obligations in respect of such series of Securities and
(solely in the case of Note Guarantees of the

<Page>

                                                                             104

Senior Subordinated Notes) all obligations to which the Guaranteed Obligations
are subordinated as provided in Article 12. Each Note Guarantor of a series of
Securities further agrees that, as between it, on the one hand, and the Holders
in respect of such series of Securities and the Trustee, on the other hand, (i)
the maturity of the Guaranteed Obligations in respect of such series of
Securities hereby may be accelerated as provided in Article 6 for the purposes
of such Note Guarantor's Note Guaranty in respect of such series of Securities
herein, notwithstanding any stay, injunction or other prohibition preventing
such acceleration in respect of the Guaranteed Obligations in respect of such
series of Securities guaranteed hereby, and (ii) in the event of any declaration
of acceleration of such Guaranteed Obligations as provided in Article 6, such
Guaranteed Obligations (whether or not due and payable) shall forthwith become
due and payable by such Note Guarantor for the purposes of this Section.

          (h)    Each Note Guarantor also agrees to pay any and all costs and
expenses (including reasonable attorneys' fees) incurred by the Trustee or any
Holder in enforcing any rights under this Section.

          SECTION 11.02     LIMITATION ON LIABILITY. Any term or provision of
this Indenture to the contrary notwithstanding, the maximum aggregate amount of
the Guaranteed Obligations in respect of a series of Securities guaranteed
hereunder by any Note Guarantor shall not exceed the maximum amount that can be
hereby guaranteed without rendering this Indenture, as it relates to such Note
Guarantor, voidable under applicable law relating to fraudulent conveyance or
fraudulent transfer or similar laws affecting the rights of creditors generally.

          SECTION 11.03     SUCCESSORS AND ASSIGNS. This Article 11 shall be
binding upon each Note Guarantor and its successors and assigns and shall enure
to the benefit of the successors and assigns of the Trustee and the Holders and,
in the event of any transfer or assignment of rights by any Holder or the
Trustee, the rights and privileges conferred upon that party in this Indenture
and in the Securities shall automatically extend to and be vested in such
transferee or assignee, all subject to the terms and conditions of this
Indenture.

          SECTION 11.04     NO WAIVER. Neither a failure nor a delay on the part
of either the Trustee or the Holders in exercising any right, power or privilege
under this Article 11 shall operate as a waiver thereof, nor shall a single or
partial exercise thereof preclude any other or further exercise of any right,
power or privilege. The rights, remedies and benefits of the Trustee and the
Holders herein expressly specified are cumulative and not exclusive of any other
rights, remedies or benefits which either may have under this Article 11 at law,
in equity, by statute or otherwise.

          SECTION 11.05     MODIFICATION. No modification, amendment or waiver
of any provision of this Article 11, nor the consent to any departure by any
Note Guarantor therefrom, shall in any event be effective unless the same shall
be in writing and signed by the Trustee, and then such waiver or consent shall
be effective only in the specific instance and for the purpose for which given.
No notice to or demand on any

                                                                             105

Note Guarantor in any case shall entitle such Note Guarantor to any other or
further notice or demand in the same, similar or other circumstances.

          SECTION 11.06     RELEASE OF NOTE GUARANTOR. A Note Guarantor shall be
released automatically from its obligations under this Article 11 (other than
any obligation that may have arisen under Section 11.07)

          (1)    upon the sale or other disposition (including by way of
     consolidation or merger) of a Subsidiary Guarantor or Cross Guarantor,
     including the sale or disposition of Capital Stock of a Subsidiary
     Guarantor or a Cross Guarantor, following which (i) if such Subsidiary
     Guarantor or Cross Guarantor (other than Timber Holdings) is not a
     Timberlands Entity, such Subsidiary Guarantor or Cross Guarantor is no
     longer a Subsidiary of Boise Holdings or Timber Holdings or (ii) if such
     Subsidiary Guarantor or Cross Guarantor is a Timberlands Entity, none of
     Boise Holdings, Timber Holdings or any of their respective Restricted
     Subsidiaries or, in the case of Timber Holdings, Parent, owns any Capital
     Stock of such Subsidiary Guarantor or Cross Guarantor; or

          (2)    the sale or disposition of all or substantially all the assets
     of a Subsidiary Guarantor or such a Cross Guarantor;

PROVIDED, HOWEVER, that in the case of clauses (1) and (2) above, (i) such sale
or other disposition is made to a Person other than the Issuers or an Affiliate
of the Issuers, (ii) such sale or disposition is otherwise permitted by this
Indenture and (iii) the Issuers provide an Officers' Certificate to the Trustee
to the effect that the Issuers and each of Boise Holdings and Timber Holdings
shall comply with their obligations under Section 4.06. The Subsidiary
Guaranties of a Subsidiary Guarantor and the Cross Guaranties of a Cross
Guarantor also shall be automatically released:

          (1)    upon the designation of such Subsidiary Guarantor or Cross
     Guarantor as an Unrestricted Subsidiary;

          (2)    at such time as such Subsidiary Guarantor or Cross Guarantor
     does not have any Indebtedness outstanding that would have required such
     Subsidiary Guarantor or Cross Guarantor to enter into a Guaranty Agreement
     pursuant to Section 4.12 (other than the Senior Subordinated Notes, the
     Senior Notes and Guarantees thereof, as the case may be) and such
     Subsidiary Guarantor or Cross Guarantor is not a Timberlands Entity; or

          (3)    if the Issuers exercise their legal defeasance option or their
     covenant defeasance option under Section 8.01 (solely with respect to
     Guaranties of the Senior Subordinated Notes), or if their obligations under
     this Indenture are discharged in accordance with the terms of this
     Indenture.

Notwithstanding the foregoing, in the event of any sale, transfer or other
disposition of a Timberlands Parent Entity (or its Capital Stock), such
Timberlands Parent Entity's obligations under its Note Guaranties will not be
released unless (i) at the time of such sale, transfer or other disposition such
Timberlands Parent Entity and its Restricted

                                                                             106

Subsidiaries do not own or control any material assets or operations other than
Timberlands Assets, (ii) the Net Available Cash from such sale, transfer or
other disposition is concurrently contributed to Boise Holdings as common equity
(a "Timberlands Contribution"), except to the extent such Net Available Cash is
then distributable pursuant to Section 4.04(b)(13) (in which case any such Net
Available Cash not so contributed shall be deemed to have been contributed as a
Timberlands Contribution to Boise Holdings and distributed as a dividend
pursuant to such Section 4.04(b)(13)) and (iii) the proceeds of such Timberlands
Contribution are applied as Timberlands Proceeds in accordance with Section
4.06.

          At the request of the Issuers, the Trustee shall execute and deliver
an appropriate instrument evidencing such release.

          SECTION 11.07     CONTRIBUTION. Each Note Guarantor that makes a
payment under its Note Guaranty shall be entitled upon payment in full of all
Guaranteed Obligations under this Indenture to a contribution from each other
Note Guarantor in an amount equal to such other Note Guarantor's PRO RATA
portion of such payment based on the respective net assets of all the Note
Guarantors at the time of such payment determined in accordance with GAAP.

                                   Article 12

                        SUBORDINATION OF NOTE GUARANTIES

          SECTION 12.01     AGREEMENT TO SUBORDINATE. Each Note Guarantor of
Senior Subordinated Notes agrees, and each Holder of Senior Subordinated Notes
by accepting a Senior Subordinated Note agrees, that the Indebtedness evidenced
by such Note Guarantor's Note Guaranty of Senior Subordinated Notes is
subordinated in right of payment, to the extent and in the manner provided in
this Article 12, to the prior payment of all Senior Indebtedness of such Note
Guarantor (including its Note Guaranty of the Senior Notes) and that the
subordination is for the benefit of and enforceable by the holders of such
Senior Indebtedness. The Obligations of a Note Guarantor in respect of a Note
Guaranty of the Senior Subordinated Notes shall in all respects rank PARI PASSU
with all other Senior Subordinated Indebtedness of such Note Guarantor and only
Senior Indebtedness of such Note Guarantor (including such Note Guarantor's
Guaranty of Senior Indebtedness of the Issuers) shall rank senior to the
Obligations of such Note Guarantor in respect of the Senior Subordinated Notes
in accordance with the provisions set forth herein.

          SECTION 12.02     LIQUIDATION, DISSOLUTION, BANKRUPTCY. Upon any
payment or distribution of the assets of any Note Guarantor to creditors upon a
total or partial liquidation or a total or partial dissolution of such Note
Guarantor or in a bankruptcy, reorganization, insolvency, receivership or
similar proceeding relating to such Note Guarantor or its property:

          (1)    holders of Senior Indebtedness of such Note Guarantor shall be
     entitled to receive payment in full in cash of such Senior Indebtedness
     before

<Page>

                                                                             107

     Holders of Senior Subordinated Notes shall be entitled to receive any
     payment pursuant to the Note Guaranty of the Senior Subordinated Notes of
     such Note Guarantor; and

          (2)    until the Senior Indebtedness of such Note Guarantor is paid in
     full in cash, any payment or distribution to which Holders of Senior
     Subordinated Notes would be entitled but for this Article 12 shall be made
     to holders of such Senior Indebtedness as their interests may appear,
     except that Holders of Senior Subordinated Notes may receive shares of
     stock and any debt securities of such Note Guarantor that are subordinated
     to such Senior Indebtedness to at least the same extent as the Note
     Guaranty of the Senior Subordinated Notes.

          SECTION 12.03     DEFAULT ON SENIOR INDEBTEDNESS OF NOTE GUARANTOR.
(a) A Note Guarantor shall not make payment on its Note Guaranty of the Senior
Subordinated Notes or purchase, redeem or otherwise retire or defease any Senior
Subordinated Notes or other Obligations in respect of the Senior Subordinated
Notes (collectively, "pay its Note Guaranty") if either of the following (a
"Guaranty Payment Default") occurs:

          (1)    any Obligation on any Designated Senior Indebtedness of such
     Note Guarantor is not paid in full in cash when due; or

          (2)    any other default on Designated Senior Indebtedness of such
     Note Guarantor occurs and the maturity of such Designated Senior
     Indebtedness is accelerated in accordance with its terms;

unless, in either case, the Guaranty Payment Default has been cured or waived
and any such acceleration has been rescinded or such Designated Senior
Indebtedness has been paid in full in cash; PROVIDED, HOWEVER, that any Note
Guarantor shall be entitled to pay its Note Guaranty of the Senior Subordinated
Notes without regard to the foregoing if such Note Guarantor and the Trustee
receive written notice approving such payment from the Representatives of all
Designated Senior Indebtedness with respect to which the Guaranty Payment
Default has occurred and is continuing.

          (b)    During the continuance of any default (other than a Guaranty
Payment Default) with respect to any Designated Senior Indebtedness of a Note
Guarantor pursuant to which the maturity thereof may be accelerated without
further notice (except such notice as may be required to effect such
acceleration) or the expiration of any applicable grace periods, such Note
Guarantor shall not pay its Note Guaranty of the Senior Subordinated Notes for a
period (a "Guaranty Payment Blockage Period") commencing upon the receipt by the
Trustee (with a copy to such Note Guarantor) of written notice (a "Guaranty
Blockage Notice") of such default from the Representative of such Designated
Senior Indebtedness specifying an election to effect a Guaranty Payment Blockage
Period and ending 179 days thereafter. The Guaranty Payment Blockage Period
shall end earlier if such Guaranty Payment Blockage Period is terminated:

<Page>

                                                                             108

          (1)    by written notice to the Trustee and such Note Guarantor from
     the Person or Persons who gave such Guaranty Blockage Notice;

          (2)    because the default giving rise to such Guaranty Blockage
     Notice, and all other defaults on such Designated Senior Indebtedness, if
     any, are cured, waived or otherwise no longer continuing; or

          (3)    because such Designated Senior Indebtedness has been discharged
     or repaid in full in cash.

Notwithstanding the provisions described in the immediately preceding two
sentences (but subject to the provisions contained in the first sentence of this
Section), unless the holders of such Designated Senior Indebtedness or the
Representative of such Designated Senior Indebtedness shall have accelerated the
maturity of such Designated Senior Indebtedness, any Note Guarantor shall be
entitled to resume payments pursuant to its Note Guaranty of the Senior
Subordinated Notes after termination of such Guaranty Payment Blockage Period.
No Note Guarantor shall be subject to more than one Guaranty Payment Blockage
Period in any consecutive 360-day period irrespective of the number of defaults
with respect to Designated Senior Indebtedness of such Note Guarantor during
such period; PROVIDED, HOWEVER, that if any Guaranty Blockage Notice within such
360-day period is delivered to the Trustee by or on behalf of any holders of
Designated Senior Indebtedness of such Note Guarantor (other than holders of
Indebtedness under any Credit Agreement), the Representative of the holders of
Indebtedness under any Credit Agreement shall be entitled to give another
Guaranty Blockage Notice within such period; PROVIDED FURTHER, HOWEVER, that in
no event shall the total number of days during which any Guaranty Payment
Blockage Period or Periods is in effect exceed 179 days in the aggregate during
any consecutive 360-day period, and there must be 181 days during any
consecutive 360-day period during which no Guaranty Payment Blockage Period is
in effect.

          SECTION 12.04     DEMAND FOR PAYMENT. If a demand for payment is made
on a Note Guarantor in respect of its Note Guaranty of Senior Subordinated Notes
pursuant to Article 11, the Trustee shall promptly notify the holders of the
Designated Senior Indebtedness of such Note Guarantor (or their Representatives)
of such demand.

          SECTION 12.05     WHEN DISTRIBUTION MUST BE PAID OVER. If a
distribution is made to Holders of Senior Subordinated Notes that because of
this Article 12 should not have been made to them, the Holders of Senior
Subordinated Notes who receive such distribution shall hold such distribution in
trust for the holders of Senior Indebtedness of the applicable Note Guarantor
and pay it over to them as their interests may appear.

          SECTION 12.06     SUBROGATION. After all Senior Indebtedness of a Note
Guarantor is paid in full and until the Senior Subordinated Notes are paid in
full, Holders of Senior Subordinated Notes shall be subrogated to the rights of
holders of such Senior Indebtedness to receive distributions applicable to such
Senior Indebtedness of such Note Guarantor. A distribution made under this
Article 12 to holders of such Senior

<Page>

                                                                             109

Indebtedness which otherwise would have been made to Holders of Senior
Subordinated Notes is not, as between the relevant Note Guarantor and Holders of
Senior Subordinated Notes, a payment by such Note Guarantor on such Senior
Indebtedness.

          SECTION 12.07     RELATIVE RIGHTS. This Article 12 defines the
relative rights of Holders of Senior Subordinated Notes and holders of Senior
Indebtedness of a Note Guarantor. Nothing in this Indenture shall:

          (1)    impair, as between a Note Guarantor and Holders of Senior
     Subordinated Notes, the obligation of such Note Guarantor, which is
     absolute and unconditional, to pay its Note Guaranty to the extent set
     forth in Article 11; or

          (2)    prevent the Trustee or any Holder of Senior Subordinated Notes
     from exercising its available remedies upon a Default by such Note
     Guarantor under its Note Guaranty in respect of the Senior Subordinated
     Notes, subject to the rights of holders of Senior Indebtedness of such Note
     Guarantor to receive distributions otherwise payable to Holders of Senior
     Subordinated Notes.

          SECTION 12.08     SUBORDINATION MAY NOT BE IMPAIRED BY NOTE
GUARANTORS. No right of any holder of Senior Indebtedness of any Note Guarantor
to enforce the subordination of the Note Guaranty of the Senior Subordinated
Notes of such Note Guarantor shall be impaired by any act or failure to act by
such Note Guarantor or by its failure to comply with this Indenture.

          SECTION 12.09     RIGHTS OF TRUSTEE AND PAYING AGENT. Notwithstanding
Section 12.03, the Trustee or Paying Agent shall continue to make payments on
any Note Guaranty of the Senior Subordinated Notes and shall not be charged with
knowledge of the existence of facts that under this Article 12 would prohibit
the making of any such payments unless, not less than two Business Days prior to
the date of such payment, a Trust Officer of the Trustee receives notice
satisfactory to it that such payments are prohibited by this Article 12. The
Issuers, the relevant Note Guarantor, the Registrar or co-registrar, the Paying
Agent, a Representative or a holder of Senior Indebtedness of such Note
Guarantor shall be entitled to give the notice; PROVIDED, HOWEVER, that, if an
issue of Senior Indebtedness of any Note Guarantor has a Representative, only
the Representative shall be entitled to give the notice.

          The Trustee in its individual or any other capacity shall be entitled
to hold Senior Indebtedness of any Note Guarantor with the same rights it would
have if it were not Trustee. The Registrar and co-registrar and the Paying Agent
shall be entitled to do the same with like rights. The Trustee shall be entitled
to all the rights set forth in this Article 12 with respect to any Senior
Indebtedness of any Note Guarantor which may at any time be held by it, to the
same extent as any other holder of such Senior Indebtedness; and nothing in
Article 7 shall deprive the Trustee of any of its rights as such holder. Nothing
in this Article 12 shall apply to claims of, or payments to, the Trustee under
or pursuant to Section 7.07.

<Page>

                                                                             110

          SECTION 12.10     DISTRIBUTION OR NOTICE TO REPRESENTATIVE. Whenever
any Person is to make a distribution or give a notice to holders of Senior
Indebtedness of any Note Guarantor, such Person shall be entitled to make such
distribution or give such notice to their Representative (if any).

          SECTION 12.11     NOT TO PREVENT EVENTS OF DEFAULT OR LIMIT RIGHT TO
DEMAND PAYMENT. The failure to make a payment pursuant to a Note Guaranty of the
Senior Subordinated Notes by reason of any provision in this Article 12 shall
not be construed as preventing the occurrence of a Default. Nothing in this
Article 12 shall have any effect on the right of the Holders of Senior
Subordinated Notes or the Trustee to make a demand for payment on any Note
Guarantor pursuant to its Note Guaranty of the Senior Subordinated Notes.

          SECTION 12.12     TRUSTEE ENTITLED TO RELY. Upon any payment or
distribution pursuant to this Article 12, the Trustee and the Holders of Senior
Subordinated Notes shall be entitled to rely (a) upon any order or decree of a
court of competent jurisdiction in which any proceedings of the nature referred
to in Section 12.02 are pending, (b) upon a certificate of the liquidating
trustee or agent or other Person making such payment or distribution to the
Trustee or to the Holders of Senior Subordinated Notes or (c) upon the
Representatives of Senior Indebtedness of any Note Guarantor for the purpose of
ascertaining the Persons entitled to participate in such payment or
distribution, the holders of such Senior Indebtedness and other Indebtedness of
such Note Guarantor, the amount thereof or payable thereon, the amount or
amounts paid or distributed thereon and all other facts pertinent thereto or to
this Article 12. In the event that the Trustee determines, in good faith, that
evidence is required with respect to the right of any Person as a holder of
Senior Indebtedness of any Note Guarantor to participate in any payment or
distribution pursuant to this Article 12, the Trustee shall be entitled to
request such Person to furnish evidence to the reasonable satisfaction of the
Trustee as to the amount of such Senior Indebtedness of such Note Guarantor held
by such Person, the extent to which such Person is entitled to participate in
such payment or distribution and other facts pertinent to the rights of such
Person under this Article 12, and, if such evidence is not furnished, the
Trustee shall be entitled to defer any payment to such Person pending judicial
determination as to the right of such Person to receive such payment. The
provisions of Sections 7.01 and 7.02 shall be applicable to all actions or
omissions of actions by the Trustee pursuant to this Article 12.

          SECTION 12.13     TRUSTEE TO EFFECTUATE SUBORDINATION. Each Holder of
Senior Subordinated Notes by accepting a Senior Subordinated Note authorizes and
directs the Trustee on his behalf to take such action as may be necessary or
appropriate to acknowledge or effectuate the subordination between the Holders
of Senior Subordinated Notes and the holders of Senior Indebtedness of any Note
Guarantor as provided in this Article 12 and appoints the Trustee as
attorney-in-fact for any and all such purposes.

          SECTION 12.14     TRUSTEE NOT FIDUCIARY FOR HOLDERS OF SENIOR
INDEBTEDNESS OF NOTE GUARANTOR. The Trustee shall not be deemed to owe any
fiduciary duty to the holders of Senior Indebtedness of any Note Guarantor
pursuant to this Article 12 and shall not be liable to any such holders if it
shall mistakenly pay over or distribute

<Page>

                                                                             111

to Holders of Senior Subordinated Notes or the Issuers or any other Person,
money or assets to which any holders of such Senior Indebtedness shall be
entitled by virtue of this Article 12.

          SECTION 12.15     RELIANCE BY HOLDERS OF SENIOR INDEBTEDNESS OF NOTE
GUARANTORS ON SUBORDINATION PROVISIONS. Each Holder of Senior Subordinated Notes
by accepting a Senior Subordinated Note acknowledges and agrees that the
foregoing subordination provisions are, and are intended to be, an inducement
and a consideration to each holder of any Senior Indebtedness of any Note
Guarantor, whether such Senior Indebtedness was created or acquired before or
after the issuance of the Senior Subordinated Notes, to acquire and continue to
hold, or to continue to hold, such Senior Indebtedness and such holder of such
Senior Indebtedness shall be deemed conclusively to have relied on such
subordination provisions in acquiring and continuing to hold, or in continuing
to hold, such Senior Indebtedness.

concurred in any direction, waiver or consent, Securities of such series owned
by the Issuers or by any Person directly or indirectly controlling or controlled

disregarded and deemed not to be outstanding, except that, for the purpose of
determining whether the Trustee shall be protected in relying on any such
direction, waiver or consent, only Securities which the Trustee knows are so
owned shall be so disregarded. Also, subject to the foregoing, only Securities
outstanding at the time shall be considered in any such determination.

          SECTION 13.07     RULES BY TRUSTEE, PAYING AGENT AND REGISTRAR. The

     2.   THE SECURITIES.

     2.1  (a) FORM AND DATING. The Initial Securities will be offered and sold
by the Issuers pursuant to a Purchase Agreement. The Initial Securities will be
resold initially only to (i) QIBs in reliance on Rule 144A under the Securities
Act ("Rule 144A") and (ii) Persons other than U.S. Persons (as defined in
Regulation S) in reliance on Regulation S under the Securities Act ("Regulation
S"). Initial Securities may thereafter be transferred to, among others, QIBs,
IAIs and purchasers in reliance on Regulation S, subject to the restrictions on
transfer set forth herein. Initial Senior Notes and Initial Senior Subordinated
Notes initially resold pursuant to Rule 144A shall be issued initially in the
form of one or more permanent global Securities in definitive, fully registered
form (the "Rule 144A Global Senior Security" and the "Rule 144A Global Senior
Subordinated Security", respectively, and each, a "Rule 144A Global Security");
Initial Senior Notes and Initial Senior Subordinated Notes subsequently resold
to IAIs shall be issued initially in the form of one or more permanent global
Securities in definitive, fully registered form (the "IAI Global Senior
Security" and the "IAI Global Senior Subordinated Security", respectively, and
each, an "IAI Global Security"); and Initial Senior Notes and Initial Senior
Subordinated Notes initially resold pursuant to Regulation S shall be issued
initially in the form of one or more temporary global securities in fully
registered form (the "Temporary Regulation S Global Senior Security" and the
"Temporary Regulation S Global Senior Subordinated Security", respectively, and
each, a "Temporary Regulation S Global Security"), in each case without interest
coupons and with the global securities legend and the restricted securities
legend set forth in Exhibit 1 hereto, which shall be deposited on behalf of the
purchasers of the Initial Securities represented thereby with the Securities
Custodian and registered in the name of the Depository or a nominee of the
Depository, duly executed by the Issuers and authenticated by the Trustee as
provided in this Indenture. Except as set forth in this Section 2.1(a),
beneficial ownership interests in a Temporary Regulation S Global Security will
not be exchangeable for interests in a Rule 144A Global Security, an IAI Global
Security, a permanent global security (a "Permanent Regulation S Global
Security", and together with the Temporary Regulation S Global Security, the
"Regulation S Global Security") or any other Security prior to the expiration of
the Distribution Compliance Period and then, after the expiration of the
Distribution Compliance Period, may be exchanged for interests in a Rule 144A
Global Security, an IAI Global Security or a Permanent Regulation S Global
Security only upon certification in form reasonably satisfactory to the Trustee
that (i) beneficial ownership interests in such Temporary Regulation S Global
Security are owned either by non-U.S. persons or U.S. persons who purchased such
interests in a transaction that did not require registration under the
Securities Act and (ii) in the case of an exchange for an IAI Global Security,
certification that the interest in the Temporary Regulation S Global Security is
being transferred to an institutional "accredited investor" under the Securities
Act that is an institutional accredited investor acquiring the securities for
its own account or for the account of an institutional accredited investor.

          Beneficial interests in Temporary Regulation S Global Securities or
IAI Global Securities may be exchanged for interests in Rule 144A Global
Securities if (1)

<Page>

                                                                               5

such exchange occurs in connection with a transfer of Securities in compliance
with Rule 144A and (2) the transferor of the beneficial interest in the
Temporary Regulation S Global Security or the IAI Global Security, as
applicable, first delivers to the Trustee a written certificate (in a form
satisfactory to the Trustee) to the effect that the beneficial interest in the
Temporary Regulation S Global Security or the IAI Global Security, as
applicable, is being transferred to a Person (a) who the transferor reasonably
believes to be a QIB, (b) purchasing for its own account or the account of a QIB
in a transaction meeting the requirements of Rule 144A, and (c) in accordance
with all applicable securities laws of the States of the United States and other
jurisdictions.

          Beneficial interests in Temporary Regulation S Global Securities and
Rule 144A Global Securities may be exchanged for an interest in IAI Global
Securities if (1) such exchange occurs in connection with a transfer of the
securities in compliance with an exemption under the Securities Act and (2) the
transferor of the Regulation S Global Security or Rule 144A Global Security, as
applicable, first delivers to the trustee a written certificate (substantially
in the form of Exhibit C to this Indenture) to the effect that (A) the
Regulation S Global Security or Rule 144A Global Security, as applicable, is
being transferred (a) to an "accredited investor" within the meaning of
501(a)(1),(2),(3) or (7) under the Securities Act that is an institutional
investor acquiring the securities for its own account or for the account of such
an institutional accredited investor, in each case in a minimum principal amount
of the securities of $250,000, 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 (B) in accordance with all applicable securities laws of the
States of the United States and other jurisdictions.

          Beneficial interests in a Rule 144A Global Security or an IAI Global
Security may be transferred to a Person who takes delivery in the form of an
interest in a Regulation S Global Security, whether before or after the
expiration of the Distribution Compliance Period, only if the transferor first
delivers to the Trustee a written certificate (in the form of the "Assignment
Form" included in Exhibit 1 or 2 to this Appendix, as applicable) to the effect
that such transfer is being made in accordance with Rule 903 or 904 of
Regulation S or Rule 144 (if applicable).

          The Rule 144A Global Securities, the IAI Global Securities, the
Temporary Regulation S Global Securities and the Permanent Regulation S Global
Securities are collectively referred to herein as "Global Securities". The
aggregate principal amount of the Global Securities may from time to time be
increased or decreased by adjustments made on the records of the Trustee and the
Depository or its nominee as hereinafter provided.

          (b)    BOOK-ENTRY PROVISIONS. This Section 2.1(b) shall apply only to
a Global Security deposited with or on behalf of the Depository.

          The Issuers shall execute and the Trustee shall, in accordance with

          Members of, or participants in, the Depository ("Agent Members") shall
have no rights under this Indenture with respect to any Global Security held on
their behalf by the Depository or by the Trustee as the custodian of the
Depository or under such Global Security, and the Issuers, the Trustee and any
agent of the Issuers or the Trustee shall be entitled to treat the Depository as
the absolute owner of such Global Security for all purposes whatsoever.
Notwithstanding the foregoing, nothing herein shall prevent the Issuers, the
Trustee or any agent of the Issuers or the Trustee from giving effect to any
written certification, proxy or other authorization furnished by the Depository
or impair, as between the Depository and its Agent Members, the operation of
customary practices of such Depository governing the exercise of the rights of a
holder of a beneficial interest in any Global Security.

          (c)    DEFINITIVE SECURITIES. Except as provided in Section 2.3 or
2.4, owners of beneficial interests in Global Securities shall not be entitled

original issue in an aggregate principal amount specified in the written order
of the Issuers pursuant to Section 2.02 of the Indenture and (3) Exchange
Securities for issue only in a Registered Exchange Offer pursuant to a
Registration Rights Agreement, for a like principal amount of Initial Securities
of the same series, in each case upon a written order of the Issuers signed by
two Officers or by an Officer and either an Assistant Treasurer or an Assistant
Secretary of the Issuers. Such order shall specify the amount of the Securities
to be authenticated and the date on which the original issue of Securities is to
be authenticated and, in the case of any issuance of Additional Securities
pursuant to Section 2.13 of the Indenture, shall certify that such issuance is
in compliance with Section 4.03 of the Indenture.

          equal to the principal amount of the interest to be so transferred,
          and the Registrar shall reflect on its books and records the date and
          a corresponding decrease in the principal amount of the Global
          Security from which such interest is being transferred.

               (iii)   Notwithstanding any other provisions of this Appendix
          (other than the provisions set forth in Section 2.4), a Global
          Security may not be transferred as a whole except by the Depository to
          a nominee of the Depository or by a nominee of the Depository to the
          Depository or another nominee of the Depository or by the Depository
          or any such nominee to a successor Depository or a nominee of such
          successor Depository.

               (iv)    In the event that a Global Security is exchanged for
          Definitive Securities pursuant to Section 2.4 of this Appendix, prior
          to the consummation of a Registered Exchange Offer or the
          effectiveness of a Shelf Registration Statement with respect to such
          Securities, such Securities may be exchanged only in accordance with
          such procedures as are substantially consistent with the provisions of
          this Section 2.3 (including the certification requirements set forth
          on the reverse of the Initial Securities intended to ensure that such
          transfers comply with Rule 144A, Regulation S or another applicable
          exemption under the Securities Act, as the case may be) and such other
          procedures as may from time to time be adopted by the Issuers.

          (d)    RESTRICTIONS ON TRANSFER OF TEMPORARY REGULATION S GLOBAL
SECURITIES. During the Distribution Compliance Period, beneficial ownership
interests in Temporary Regulation S Global Securities may only be sold, pledged
or transferred in accordance with the Applicable Procedures and only (1) to the
Issuers, (2) so long as such security is eligible for resale pursuant to Rule
144A, to a person whom the selling holder reasonably believes is a QIB that
purchases for its own account or for the account of a QIB to whom notice is
given that the resale, pledge or transfer is being made in reliance on Rule
144A, (3) in an offshore transaction in accordance with Regulation S (other than
a transaction resulting in an exchange for an interest in a Permanent Regulation
S Global Security), (4) pursuant to an exemption from registration under the
Securities Act provided by Rule 144 (if applicable) under the Securities Act,
(5) to an IAI purchasing for its own account, or for the account of such an IAI,
in a minimum principal amount of Securities of $250,000 or (6) pursuant to an
effective registration statement under the Securities Act, in each case in
accordance with any applicable securities laws of any state of the United
States. Upon the expiration of the Distribution Compliance Period, beneficial
ownership interests in the Regulation S Global Security shall be transferable in
accordance with applicable law and the other terms of this Indenture.

                 OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR THE SECURITIES

                 EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES
                 ACT, SUBJECT TO THE ISSUERS' AND THE TRUSTEE'S RIGHT PRIOR TO
                 ANY SUCH OFFER, SALE OR TRANSFER PURSUANT TO CLAUSES (D), (E)

                 CERTIFICATION AND/OR OTHER INFORMATION SATISFACTORY TO EACH OF
                 THEM. THIS LEGEND WILL BE REMOVED UPON THE REQUEST OF THE
                 HOLDER AFTER THE RESALE RESTRICTION TERMINATION DATE.

          Each Definitive Security shall also bear the following additional
legend:

                 IN CONNECTION WITH ANY TRANSFER, THE HOLDER WILL DELIVER TO THE
                 REGISTRAR AND TRANSFER AGENT SUCH CERTIFICATES AND OTHER
                 INFORMATION AS SUCH TRANSFER AGENT MAY REASONABLY REQUIRE TO
                 CONFIRM THAT THE TRANSFER COMPLIES WITH THE FOREGOING
                 RESTRICTIONS.

               (ii)    Upon any sale or transfer of a Transfer Restricted
          Security (including any Transfer Restricted Security represented by a
          Global Security) pursuant to Rule 144 under the Securities Act, the
          Registrar shall permit the transferee thereof to exchange such
          Transfer Restricted Security for a Definitive Security that does not
          bear the legend set forth above and rescind any restriction on the
          transfer of such Transfer Restricted Security, if the transferor
          thereof certifies in writing to the Registrar that such sale or
          transfer was made in reliance on Rule 144 (such certification to be in
          the form set forth on the reverse of the Security).

               (iii)   After a transfer of any Initial Securities pursuant to
          and during the period of the effectiveness of a Shelf Registration
          Statement with respect to such Initial Securities, all requirements
          pertaining to legends on such Initial Security will cease to apply,
          the requirements requiring any such Initial Security issued to certain
          Holders be issued in global form will cease to apply, and a
          certificated Initial Security or an Initial Security in global form,
          in each case without restrictive transfer legends, will be available
          to the transferee of the Holder of such Initial Securities upon
          exchange of such transferring Holder's certificated Initial Security
          or directions to transfer such Holder's interest in the Global
          Security, as applicable.

               (iv)    Upon the consummation of a Registered Exchange Offer with
          respect to the Initial Securities, all requirements pertaining to such
          Initial Securities that Initial Securities issued to certain Holders
          be issued in global form will still apply with respect to Holders of
          such Initial Securities that do not exchange their Initial Securities,
          and Exchange Securities in certificated or global form, in each case
          without the restricted securities legend set forth in Exhibit 1 hereto
          will be available to Holders that exchange such Initial Securities in
          such Registered Exchange Offer.

               (v)     Upon a sale or transfer after the expiration of the
          Distribution Compliance Period of any Initial Security acquired
          pursuant to Regulation S, all requirements that such Initial Security
          bear the Restricted Securities Legend shall cease to apply and the
          requirements requiring any such Initial Security be issued in global
          form shall continue to apply.

          (f)    CANCELLATION OR ADJUSTMENT OF GLOBAL SECURITY. At such time as
all beneficial interests in a Global Security have either been exchanged for
Definitive Securities, redeemed, purchased or canceled, such Global Security
shall be returned to the Depository for cancellation or retained and canceled by
the Trustee. At any time prior to such cancellation, if any beneficial interest
in a Global Security is exchanged for Definitive Securities, redeemed, purchased
or canceled, the principal amount of Securities represented by such Global
Security shall be reduced and an adjustment shall be made on the books and
records of the Trustee (if it is then the Securities Custodian for such Global
Security) with respect to such Global Security, by the Trustee or the Securities
Custodian, to reflect such reduction.

          (g)    NO OBLIGATION OF THE TRUSTEE.

               (i)     The Trustee shall have no responsibility or obligation to
          any beneficial owner of a Global Security, a member of, or a
          participant in the Depository or other Person with respect to the
          accuracy of the records of the Depository or its nominee or of any
          participant or member thereof, with respect to any ownership interest
          in the Securities or with respect to the delivery to any participant,
          member, beneficial owner or other Person (other than the Depository)
          of any notice (including any notice of redemption) or the payment of
          any amount, under or with respect to such Securities. All notices and
          communications to be given to the Holders and all payments to be made
          to Holders under the Securities shall be given or made only to or upon
          the order of the registered Holders (which shall be the Depository or
          its nominee in the case of a Global Security). The rights of
          beneficial owners in any Global Security shall be exercised only
          through the Depository subject to the applicable rules and procedures
          of the Depository. The Trustee may rely and shall be fully protected
          in relying upon information furnished by the Depository with respect
          to its members, participants and any beneficial owners.

               (ii)    The Trustee shall have no obligation or duty to monitor,
          determine or inquire as to compliance with any restrictions on
          transfer imposed under this Indenture or under applicable law with
          respect to any transfer of any interest in any Security (including any
          transfers between or among Depository participants, members or
          beneficial owners in any Global Security) other than to require
          delivery of such certificates and other documentation or evidence as
          are expressly required by, and to do so if and when expressly required
          by, the terms of this Indenture, and to examine the same to determine
          substantial compliance as to form with the express requirements
          hereof.

          2.4    DEFINITIVE SECURITIES.

          (a)    A Global Security deposited with the Depository or with the
Trustee as Securities Custodian for the Depository pursuant to Section 2.1 shall
be transferred to the beneficial owners thereof in the form of Definitive
Securities in an aggregate principal amount equal to the principal amount of
such Global Security, in exchange for such Global Security, only if such
transfer complies with Section 2.3 hereof and (i) the Depository notifies the
Issuers that it is unwilling or unable to continue as Depository for such Global
Security and the Depository fails to appoint a successor depository or if at any
time such Depository ceases to be a "clearing agency" registered under the
Exchange Act and, in either case, a successor depository is not appointed by the
Issuers within 90 days of such notice, or (ii) an Event of Default has occurred
and is continuing or (iii) the Issuers, in their sole discretion, notify the
Trustee in writing that they elect to cause the issuance of Definitive
Securities under this Indenture.

          (b)    Any Global Security that is transferable to the beneficial
owners thereof pursuant to this Section 2.4 shall be surrendered by the
Depository to the Trustee located at its principal corporate trust office in the
Borough of Manhattan, The City of New York, to be so transferred, in whole or
from time to time in part, without charge, and the Trustee shall authenticate
and deliver, upon such transfer of each portion of such Global Security, an
equal aggregate principal amount of Definitive Securities of authorized
denominations. Any portion of a Global Security transferred pursuant to this
Section 2.4 shall be executed, authenticated and delivered only in denominations
of $1,000 principal amount and any integral multiple thereof and registered in
such names as the Depository shall direct. Any Definitive Security delivered in
exchange for an interest in the Global Security shall, except as otherwise
provided by Section 2.3(e) hereof, bear the applicable restricted securities
legend and definitive securities legend set forth in Exhibit 1 hereto.

          (c)    Subject to the provisions of Section 2.4(b) hereof, the
registered Holder of a Global Security shall be entitled to grant proxies and
otherwise authorize any Person, including Agent Members and Persons that may
hold interests through Agent Members, to take any action which a Holder is
entitled to take under this Indenture or the Securities.

          (d)    In the event of the occurrence of one of the events specified
in Section 2.4(a) hereof, the Issuers shall promptly make available to the
Trustee a reasonable supply of Definitive Securities in definitive, fully
registered form without interest coupons. In the event that such Definitive
Securities are not issued, the Issuers expressly acknowledge, with respect to
the right of any Holder to pursue a remedy pursuant to Article 6 of this
Indenture, the right of any beneficial owner of Securities to pursue such remedy
with respect to the portion of the Global Security that represents such
beneficial owner's Securities as if such Definitive Securities had been issued.

                  [FORM OF REVERSE SIDE OF INITIAL SENIOR NOTE]

                       Senior Floating Rate Note due 2012

1.   INTEREST

          Boise Cascade, L.L.C., a Delaware limited liability company, and Boise
Cascade Finance Corporation, a Delaware corporation (together, and with their
successors and assigns under the Indenture hereinafter referred to, the
"Issuers"), promise to pay interest on the principal amount of this Senior Note
at a rate per annum, reset quarterly, equal to LIBOR plus 2.875%, as determined
by the Calculation Agent, which shall initially be the Trustee. The amount of
interest for each day that the Senior Notes are outstanding (the "Daily Interest
Amount") will be calculated by dividing the interest rate in effect for such day
by 360 and multiplying the result by the principal amount of the Senior Notes.
The amount of interest to be paid on the Senior Notes for each Interest Period
will be calculated by adding the Daily Interest Amounts for each day in the
Interest Period. All percentages resulting from any of the above calculations
will be rounded, if necessary, to the nearest one hundred thousandth of a
percentage point, with five one-millionths of a percentage point being rounded
upwards (e.g., 9.876545% (or .09876545) being rounded to 9.87655% (or .0987655))
and all dollar amounts used in or resulting from such calculations will be
rounded to the nearest cent (with one-half cent being rounded upwards).

          The Calculation Agent will, upon the request of any Holder of Senior
Notes, provide the interest rate then in effect with respect to the Senior
Notes. All calculations made by the Calculation Agent in the absence of manifest
error will be conclusive for all purposes and binding on the Issuers, the Note
Guarantors and the Holders of the Senior Notes.

          The Issuers will pay interest quarterly in arrears on January 15,
April 15, July 15 and October 15 of each year, commencing January 15, 2005.
Interest on the Senior Notes will accrue from the most recent date to which
interest has been paid or, if no interest has been paid, from October 29, 2004.
The Issuers will pay interest on overdue principal at the rate borne by this
Senior Note plus 1.0% per annum, and will pay interest on overdue installments
of interest at the same rate to the extent lawful. In addition, if a
Registration Default (as defined in the Registration Rights Agreement in respect
of the Senior Notes) occurs, additional interest will accrue on this Senior Note
at a rate of 0.50% per annum (increasing by an additional 0.50% per annum after
each consecutive 90-day period that occurs after the date on which such
Registration Default occurs, up to a maximum additional interest rate of 1.0%)
from and including the date on which any such Registration Default shall occur
to but excluding the date on which all Registration Defaults have been cured.
The interest rate on the Senior Notes will in no event be higher than the
maximum rate permitted by New York law as the same may be modified by United
States law of general application.

                                                                               8

2.   METHOD OF PAYMENT

          The Issuers will pay interest on the Senior Notes (except defaulted
interest) to the Persons who are registered holders of Senior Notes at the close
of business on the January 1, April 1, July 1 or October 1 next preceding the
interest payment date even if Senior Notes are canceled after the record date
and on or before the interest payment date. Holders must surrender Senior Notes
to a Paying Agent to collect principal payments. The Issuers will pay principal
and interest in money of the United States that at the time of payment is legal
tender for payment of public and private debts. Payments in respect of the
Senior Notes represented by a Global Security (including principal, premium and
interest) will be made by wire transfer of immediately available funds to the
accounts specified by the Depository. The Issuers will make all payments in
respect of a certificated Security (including principal, premium and interest)
by mailing a check to the registered address of each Holder thereof; PROVIDED,
HOWEVER, that payments on a certificated Security will be made by wire transfer
to a U.S. dollar account maintained by the payee with a bank in the United
States if such Holder elects payment by wire transfer by giving written notice
to the Trustee or the Paying Agent to such effect designating such account no
later than 30 days immediately preceding the relevant due date for payment (or
such other date as the Trustee may accept in its discretion).

3.   PAYING AGENT AND REGISTRAR

          Initially, U.S. Bank National Association, a national banking
association (the "Trustee"), will act as Paying Agent and Registrar. The Issuers
may appoint and change any Paying Agent, Registrar or co-registrar without
notice. The Issuers or any of their domestically incorporated Wholly Owned
Subsidiaries may act as Paying Agent, Registrar or co-registrar.

4.   INDENTURE

          The Issuers issued the Senior Notes under an Indenture dated as of
October 29, 2004 ("Indenture"), among the Issuers, the Note Guarantors and the
Trustee. The terms of the Senior Notes include those stated in the Indenture and
those made part of the Indenture by reference to the Trust Indenture Act of 1939
(15 U.S.C. Sections 77aaa-77bbbb) (the "Act"). Terms defined in the Indenture
and not defined herein have the meanings ascribed thereto in the Indenture. The
Senior Notes are subject to all such terms, and Securityholders are referred to
the Indenture and the Act for a statement of those terms.

          The Senior Notes are general unsecured obligations of the Issuers. The
Issuers shall be entitled, subject to their compliance with Section 4.03 of the
Indenture, to issue Additional Senior Notes pursuant to Section 2.13 of the
Indenture. The Initial Senior Notes issued on the Issue Date, any Additional
Senior Notes and all Senior Exchange Notes issued in exchange therefor will be
treated as a single class for all purposes under the Indenture. The Indenture
contains covenants that limit the ability of Boise Holdings, Timber Holdings,
the Issuers and the other Restricted Subsidiaries of Boise Holdings and Timber
Holdings to incur additional indebtedness; pay dividends or

                                                                               9

distributions on, or redeem or repurchase capital stock; make investments;
engage in transactions with affiliates; transfer or sell assets; guarantee
indebtedness; restrict dividends or other payments of subsidiaries; consolidate,
merge or transfer all or substantially all of their assets and the assets of
their subsidiaries; incur liens; and engage in sale/leaseback transactions.
These covenants are subject to important exceptions and qualifications.

5.   OPTIONAL REDEMPTION

          The Issuers shall be entitled at their option at any time and from
time to time to redeem all or a portion of the Senior Notes upon not less than
30 nor more than 60 days' notice, at the redemption prices (expressed in
percentages of principal amount on the redemption date), plus accrued interest
to the redemption date (subject to the right of Holders of record on the
relevant record date to receive interest due on the relevant interest payment
date), if redeemed during the 12-month period commencing on October 15 of the
years set forth below:

                 2007 and thereafter                   100.000%
</Table>

6.   NOTICE OF REDEMPTION

          Notice of redemption will be mailed at least 30 days but not more than
60 days before the redemption date to each Holder of Senior Notes to be redeemed
at his registered address. Senior Notes in denominations larger than $1,000
principal amount may be redeemed in part but only in whole multiples of $1,000.
If money sufficient to pay the redemption price of and accrued interest on all
Senior Notes (or portions thereof) to be redeemed on the redemption date is
deposited with the Paying Agent on or before the redemption date and certain
other conditions are satisfied, on and after such date interest ceases to accrue
on such Senior Notes (or such portions thereof) called for redemption.

7.   PUT PROVISIONS

          Upon a Change of Control, any Holder of Senior Notes will have the
right to cause the Issuers to repurchase all or any part of the Senior Notes of
such Holder at a repurchase price equal to 101% of the principal amount of the
Senior Notes to be repurchased plus accrued interest to the date of repurchase
(subject to the right of holders of record on the relevant record date to
receive interest due on the related interest payment date) as provided in, and
subject to the terms of, the Indenture.

                                                                              10

8.   GUARANTY

          The payment by the Issuers of the principal of, and premium and
interest on, the Senior Notes is fully and unconditionally guaranteed on a joint
and several senior basis by each of the Note Guarantors to the extent set forth
in the Indenture.

9.   DENOMINATIONS; TRANSFER; EXCHANGE

          The Senior Notes are in registered form without coupons in
denominations of $2,000 principal amount and integral multiples of $1,000. A
Holder may transfer or exchange Senior Notes in accordance with the Indenture.
The Registrar may require a Holder, among other things, to furnish appropriate
endorsements or transfer documents and to pay any taxes and fees required by law
or permitted by the Indenture. The Registrar need not register the transfer of
or exchange any Senior Notes selected for redemption (except, in the case of a
Senior Note to be redeemed in part, the portion of the Senior Note not to be
redeemed) or any Senior Notes for a period of 15 days before a selection of
Senior Notes to be redeemed or 15 days before an interest payment date.

10.  PERSONS DEEMED OWNERS

          The registered Holder of this Senior Note may be treated as the owner
of it for all purposes.

11.  UNCLAIMED MONEY

          If money for the payment of principal or interest remains unclaimed
for two years, the Trustee or Paying Agent shall pay the money back to the
Issuers at their request unless an abandoned property law designates another
Person. After any such payment, Holders entitled to the money must look only to
the Issuers and not to the Trustee for payment.

12.  AMENDMENT, WAIVER

          Subject to certain exceptions set forth in the Indenture, (a) the
Indenture and the Senior Notes may be amended with the written consent of the
Holders of at least a majority in principal amount outstanding of the Senior
Notes and (b) any default or noncompliance with any provision may be waived with
the written consent of the Holders of a majority in principal amount outstanding
of the Senior Notes. Subject to certain exceptions set forth in the Indenture,
without the consent of any Holder of Senior Notes, the Issuers, the Note
Guarantors and the Trustee shall be entitled to amend the Indenture with respect
to the Senior Notes or the Senior Notes to cure any ambiguity, omission, defect
or inconsistency, or to comply with Article 5 of the Indenture, or to provide
for uncertificated Securities in addition to or in place of certificated
Securities, or to add guarantees with respect to the Senior Notes, including
Note Guaranties, or to secure the Senior Notes, or to add additional covenants
or surrender rights and powers conferred on the Issuers or the Note Guarantors,
or to comply with any requirement of the SEC in connection with qualifying the
Indenture under the Act, or to make any change that does not adversely affect
the rights of any Holder of Senior Notes, or to make

                                                                              11

amendments to provisions of the Indenture relating to the form, authentication,
transfer and legending of the Senior Notes.

13.  DEFAULTS AND REMEDIES

          Under the Indenture, Events of Default include (a) default for 30 days
in payment of interest on the Senior Notes; (b) default in payment of principal
on the Senior Notes at maturity, upon redemption pursuant to paragraph 5 of the
Senior Notes, upon acceleration or otherwise, or failure by the Issuers to
purchase Senior Notes when required; (c) failure by the Issuers or any Note
Guarantor to comply with other agreements in the Indenture or the Senior Notes,
in certain cases subject to notice and lapse of time; (d) certain accelerations
(including failure to pay within any grace period after final maturity) of other
Indebtedness of the Issuers if the amount accelerated (or so unpaid) exceeds $25
million; (e) certain events of bankruptcy or insolvency with respect to the
Issuers, Boise Holdings, Timber Holdings and the Significant Subsidiaries; (f)
certain judgments or decrees for the payment of money in excess of $25 million;
and (g) certain defaults with respect to Note Guaranties. If an Event of Default
occurs and is continuing, the Trustee or the Holders of at least 25% in
principal amount of the Senior Notes may declare all the Senior Notes to be due
and payable immediately. Certain events of bankruptcy or insolvency are Events
of Default which will result in the Senior Notes being due and payable
immediately upon the occurrence of such Events of Default.

          Securityholders may not enforce the Indenture or the Senior Notes
except as provided in the Indenture. The Trustee may refuse to enforce the
Indenture or the Senior Notes unless it receives indemnity or security
satisfactory to it. Subject to certain limitations, Holders of a majority in
principal amount of the Senior Notes may direct the Trustee in its exercise of
any trust or power. The Trustee may withhold from Securityholders notice of any
continuing Default (except a Default in payment of principal or interest) if it
determines that withholding notice is in the interest of the Holders.

14.  TRUSTEE DEALINGS WITH THE ISSUERS

          Subject to certain limitations imposed by the Act, the Trustee under
the Indenture, in its individual or any other capacity, may become the owner or
pledgee of Senior Notes and may otherwise deal with and collect obligations owed
to it by the Issuers or their Affiliates and may otherwise deal with the Issuers
or their Affiliates with the same rights it would have if it were not Trustee.

15.  NO RECOURSE AGAINST OTHERS

          A director, officer, employee or stockholder, as such, of the Issuers
or the Trustee shall not have any liability for any obligations of the Issuers
under the Securities or the Indenture or for any claim based on, in respect of
or by reason of such obligations or their creation. By accepting a Security,
each Securityholder waives and releases all such liability. The waiver and
release are part of the consideration for the issue of the Securities.

Trustee (or an authenticating agent) manually signs the certificate of

18.  CUSIP NUMBERS

is made as to the accuracy of such numbers either as printed on the Senior Notes
or as contained in any notice of redemption and reliance may be placed only on

           [FORM OF REVERSE SIDE OF INITIAL SENIOR SUBORDINATED NOTE]

                    7-1/8% Senior Subordinated Note due 2014

1.   INTEREST

          Boise Cascade, L.L.C., a Delaware limited liability company, and Boise
Cascade Finance Corporation, a Delaware corporation (together, and with their
successors and assigns under the Indenture hereinafter referred to, the
"Issuers"), promise to pay interest on the principal amount of this Senior
Subordinated Note at the rate per annum shown above; PROVIDED, HOWEVER, that if
a Registration Default (as defined in the Registration Rights Agreement in
respect of the Senior Subordinated Notes) occurs, additional interest will
accrue on this Senior Subordinated Note at a rate of 0.50% per annum (increasing
by an additional 0.50% per annum after each consecutive 90-day period that
occurs after the date on which such Registration Default occurs, up to a maximum
additional interest rate of 1.0%) from and including the date on which any such
Registration Default shall occur to but excluding the date on which all
Registration Defaults have been cured. The Issuers will pay interest
semiannually in arrears on April 15 and October 15 of each year, commencing
April 15, 2005. Interest on the Senior Subordinated Notes will accrue from the
most recent date to which interest has been paid or, if no interest has been
paid, from October 29, 2004. Interest will be computed on the basis of a 360-day
year of twelve 30-day months. The Issuers will pay interest on overdue principal
at the rate borne by this Senior Subordinated Note plus 1.0% per annum, and will
pay interest on overdue installments of interest at the same rate to the extent
lawful.

2.   METHOD OF PAYMENT

          The Issuers will pay interest on the Senior Subordinated Notes (except
defaulted interest) to the Persons who are registered holders of Senior
Subordinated Notes at the close of business on the April 1 or October 1 next
preceding the interest payment date even if Senior Subordinated Notes are
canceled after the record date and on or before the interest payment date.
Holders must surrender Senior Subordinated Notes to a Paying Agent to collect
principal payments. The Issuers will pay principal and interest in money of the
United States that at the time of payment is legal tender for payment of public
and private debts. Payments in respect of the Senior Subordinated Notes
represented by a Global Security (including principal, premium and interest)
will be made by wire transfer of immediately available funds to the accounts
specified by the Depository. The Issuers will make all payments in respect of a
certificated Security (including principal, premium and interest) by mailing a
check to the registered address of each Holder thereof; PROVIDED, HOWEVER, that
payments on a certificated Security will be made by wire transfer to a U.S.
dollar account maintained by the payee with a bank in the United States if such
Holder elects payment by wire transfer by giving written notice to the Trustee
or the Paying Agent to such effect designating such account no later than 30
days immediately preceding the relevant due date for payment (or such other date
as the Trustee may accept in its discretion).

3.   PAYING AGENT AND REGISTRAR

          Initially, U.S. Bank National Association, a national banking
association (the "Trustee"), will act as Paying Agent and Registrar. The Issuers
may appoint and change any Paying Agent, Registrar or co-registrar without
notice. The Issuers or any of their domestically incorporated Wholly Owned
Subsidiaries may act as Paying Agent, Registrar or co-registrar.

dated as of October 29, 2004 ("Indenture"), among the Issuers, the Note
Guarantors and the Trustee. The terms of the Senior Subordinated Notes include
those stated in the Indenture and those made part of the Indenture by reference
to the Trust Indenture Act of 1939 (15 U.S.C. Sections 77aaa-77bbbb) (the
"Act"). Terms defined in the Indenture and not defined herein have the meanings
ascribed thereto in the Indenture. The Senior Subordinated Notes are subject to
all such terms, and Securityholders are referred to the Indenture and the Act
for a statement of those terms.

          The Senior Subordinated Notes are general unsecured obligations of the
Issuers. The Issuers shall be entitled, subject to their compliance with Section
4.03 of the Indenture, to issue Additional Senior Subordinated Notes pursuant to
Section 2.13 of the Indenture. The Initial Senior Subordinated Notes issued on
the Issue Date, any Additional Senior Subordinated Notes and all Senior
Subordinated Exchange Notes issued in exchange therefor will be treated as a
single class for all purposes under the Indenture. The Indenture contains
covenants that limit the ability of Boise Holdings, Timber Holdings, the Issuers
and the other Restricted Subsidiaries of Boise Holdings and Timber Holdings to
incur additional indebtedness; pay dividends or distributions on, or redeem or
repurchase capital stock; make investments; engage in transactions with
affiliates; transfer or sell assets; guarantee indebtedness; restrict dividends
or other payments of subsidiaries; and consolidate, merge or transfer all or
substantially all of their assets and the assets of their subsidiaries. These
covenants are subject to important exceptions and qualifications.

the Senior Subordinated Notes.

option (subject to their compliance with Section 4.04 of the Indenture) to

          In addition, prior to October 15, 2007, the Issuers shall be entitled,

of the Senior Subordinated Notes (which includes Additional Senior Subordinated
Notes, if any) plus the applicable Make-Whole Amount (as defined in the
Indenture) as of the redemption date, if any, and accrued and unpaid interest to
the redemption date (subject to the right of Holders on the relevant record date
to receive interest due on the relevant interest payment date). The Issuers
shall cause notice of such redemption to be mailed by first-class mail to each
Holder's registered address, not less than 30 nor more than 60 days prior to the
redemption date.

6.   NOTICE OF REDEMPTION

          Notice of redemption will be mailed at least 30 days but not more than
60 days before the redemption date to each Holder of Senior Subordinated Notes
to be redeemed at his registered address. Senior Subordinated Notes in
denominations larger than $1,000 principal amount may be redeemed in part but
only in whole multiples of $1,000. If money sufficient to pay the redemption
price of and accrued interest on all Senior Subordinated Notes (or portions
thereof) to be redeemed on the redemption date is deposited with the Paying
Agent on or before the redemption date and certain other conditions are
satisfied, on and after such date interest ceases to accrue on such Senior
Subordinated Notes (or such portions thereof) called for redemption.

the relevant record date to receive interest due on the related interest payment
date) as provided in, and subject to the terms of, the Indenture.

8.   GUARANTY

          The payment by the Issuers of the principal of, and premium and

guaranteed on a joint and several senior subordinated basis by each of the Note
Guarantors to the extent set forth in the Indenture.

9.   SUBORDINATION

          The Senior Subordinated Notes are subordinated to Senior Indebtedness
of the Issuers and the Note Guarantors on the terms and subject to the
conditions set forth in the Indenture. To the extent provided in the Indenture,
Senior Indebtedness must be paid before the Senior Subordinated Notes may be
paid. Each Securityholder by accepting a Senior Subordinated Note agrees to the
subordination provisions contained in the Indenture and authorizes the Trustee
to give it effect and appoints the Trustee as attorney-in-fact for such purpose.

                                                                              11

10.  DENOMINATIONS; TRANSFER; EXCHANGE

in denominations of $2,000 principal amount and integral multiples of $1,000. A
Holder may transfer or exchange Senior Subordinated Notes in accordance with the
Indenture. The Registrar may require a Holder, among other things, to furnish
appropriate endorsements or transfer documents and to pay any taxes and fees
required by law or permitted by the Indenture. The Registrar need not register
the transfer of or exchange any Senior Subordinated Notes selected for
redemption (except, in the case of a Senior Subordinated Note to be redeemed in
part, the portion of the Senior Subordinated Note not to be redeemed) or any
Senior Subordinated Notes for a period of 15 days before a selection of Senior
Subordinated Notes to be redeemed or 15 days before an interest payment date.

11.  PERSONS DEEMED OWNERS

          The registered Holder of this Senior Subordinated Note may be treated
as the owner of it for all purposes.

12.  UNCLAIMED MONEY

          If money for the payment of principal or interest remains unclaimed
for two years, the Trustee or Paying Agent shall pay the money back to the
Issuers at their request unless an abandoned property law designates another
Person. After any such payment, Holders entitled to the money must look only to
the Issuers and not to the Trustee for payment.

13.  DISCHARGE AND DEFEASANCE

          Subject to certain conditions, the Issuers at any time shall be
entitled to terminate some or all of their obligations under the Senior
Subordinated Notes and the Indenture if the Issuers deposit with the Trustee
money or U.S. Government Obligations for the payment of principal and interest
on the Senior Subordinated Notes to redemption or maturity, as the case may be.

14.  AMENDMENT, WAIVER

          Subject to certain exceptions set forth in the Indenture, (a) the
Indenture and the Senior Subordinated Notes may be amended with the written
consent of the Holders of at least a majority in principal amount outstanding of
the Senior Subordinated Notes and (b) any default or noncompliance with any
provision may be waived with the written consent of the Holders of a majority in
principal amount outstanding of the Senior Subordinated Notes. Subject to
certain exceptions set forth in the Indenture, without the consent of any Holder
of Senior Subordinated Notes, the Issuers, the Note Guarantors and the Trustee
shall be entitled to amend the Indenture with respect to the Senior Subordinated
Notes or the Senior Subordinated Notes to cure any ambiguity, omission, defect
or inconsistency, or to comply with Article 5 of the Indenture, or to provide
for uncertificated Securities in addition to or in place of certificated
Securities, or to add

guarantees with respect to the Senior Subordinated Notes, including Note
Guaranties, or to secure the Senior Subordinated Notes, or to add additional
covenants or surrender rights and powers conferred on the Issuers or the Note
Guarantors, or to comply with any requirement of the SEC in connection with
qualifying the Indenture under the Act, or to make any change that does not
adversely affect the rights of any Holder of Senior Subordinated Notes, or to
make amendments to provisions of the Indenture relating to the form,
authentication, transfer and legending of the Senior Subordinated Notes.

15.  DEFAULTS AND REMEDIES

          Under the Indenture, Events of Default include (a) default for 30 days
in payment of interest on the Senior Subordinated Notes; (b) default in payment
of principal on the Senior Subordinated Notes at maturity, upon redemption
pursuant to paragraph 5 of the Senior Subordinated Notes, upon acceleration or
otherwise, or failure by the Issuers to purchase Senior Subordinated Notes when
required; (c) failure by the Issuers or any Note Guarantor to comply with other
agreements in the Indenture or the Senior Subordinated Notes, in certain cases
subject to notice and lapse of time; (d) certain accelerations (including
failure to pay within any grace period after final maturity) of other
Indebtedness of the Issuers if the amount accelerated (or so unpaid) exceeds $25
million; (e) certain events of bankruptcy or insolvency with respect to the
Issuers, Boise Holdings, Timber Holdings and the Significant Subsidiaries; (f)
certain judgments or decrees for the payment of money in excess of $25 million;
and (g) certain defaults with respect to Note Guaranties. If an Event of Default
occurs and is continuing, the Trustee or the Holders of at least 25% in
principal amount of the Senior Subordinated Notes may declare all the Senior
Subordinated Notes to be due and payable immediately. Certain events of
bankruptcy or insolvency are Events of Default which will result in the Senior
Subordinated Notes being due and payable immediately upon the occurrence of such
Events of Default.

          Securityholders may not enforce the Indenture or the Senior
Subordinated Notes except as provided in the Indenture. The Trustee may refuse
to enforce the Indenture or the Senior Subordinated Notes unless it receives
indemnity or security satisfactory to it. Subject to certain limitations,
Holders of a majority in principal amount of the Senior Subordinated Notes may
direct the Trustee in its exercise of any trust or power. The Trustee may
withhold from Securityholders notice of any continuing Default (except a Default
in payment of principal or interest) if it determines that withholding notice is
in the interest of the Holders.

16.  TRUSTEE DEALINGS WITH THE ISSUERS

          Subject to certain limitations imposed by the Act, the Trustee under
the Indenture, in its individual or any other capacity, may become the owner or
pledgee of Senior Subordinated Notes and may otherwise deal with and collect
obligations owed to it by the Issuers or their Affiliates and may otherwise deal
with the Issuers or their Affiliates with the same rights it would have if it
were not Trustee.

17.  NO RECOURSE AGAINST OTHERS

          A director, officer, employee or stockholder, as such, of the Issuers
or the Trustee shall not have any liability for any obligations of the Issuers
under the Securities or the Indenture or for any claim based on, in respect of
or by reason of such obligations or their creation. By accepting a Security,
each Securityholder waives and releases all such liability. The waiver and
release are part of the consideration for the issue of the Securities.

18.  AUTHENTICATION

          This Security shall not be valid until an authorized signatory of the
Trustee (or an authenticating agent) manually signs the certificate of
authentication on the other side of this Security.

CUSIP numbers in notices of redemption as a convenience to Securityholders. No
representation is made as to the accuracy of such numbers either as printed on
the Senior Subordinated Notes or as contained in any notice of redemption and
reliance may be placed only on the other identification numbers placed thereon.

                 [FORM OF REVERSE SIDE OF SENIOR EXCHANGE NOTE]

                       Senior Floating Rate Note due 2012

1.   INTEREST

          Boise Cascade, L.L.C., a Delaware limited liability company, and Boise
Cascade Finance Corporation, a Delaware corporation (together, and with their
successors and assigns under the Indenture hereinafter referred to, the
"Issuers"), promise to pay interest on the principal amount of this Senior Note
at a rate per annum, reset quarterly, equal to LIBOR plus 2.875%, as determined
by the Calculation Agent, which shall initially be the Trustee. The amount of
interest for each day that the Senior Notes are outstanding (the "Daily Interest
Amount") will be calculated by dividing the interest rate in effect for such day
by 360 and multiplying the result by the principal amount of the Senior Notes.
The amount of interest to be paid on the Senior Notes for each Interest Period
will be calculated by adding the Daily Interest Amounts for each day in the
Interest Period. All percentages resulting from any of the above calculations
will be rounded, if necessary, to the nearest one hundred thousandth of a
percentage point, with five one-millionths of a percentage point being rounded
upwards (e.g., 9.876545% (or .09876545) being rounded to 9.87655% (or .0987655))
and all dollar amounts used in or resulting from such calculations will be
rounded to the nearest cent (with one-half cent being rounded upwards).

          The Calculation Agent will, upon the request of any Holder of Senior
Notes, provide the interest rate then in effect with respect to the Senior
Notes. All calculations made by the Calculation Agent in the absence of manifest
error will be conclusive for all purposes and binding on the Issuers, the Note
Guarantors and the Holders of the Senior Notes.

          The Issuers will pay interest quarterly in arrears on January 15,
April 15, July 15 and October 15 of each year, commencing January 15, 2005.
Interest on the Senior Notes will accrue from the most recent date to which
interest has been paid or, if no interest has been paid, from October 29, 2004.
The Issuers will pay interest on overdue principal at the rate borne by this
Senior Note plus 1.0% per annum, and will pay interest on overdue installments
of interest at the same rate to the extent lawful. [IN ADDITION, IF A
REGISTRATION DEFAULT (AS DEFINED IN THE REGISTRATION RIGHTS AGREEMENT IN RESPECT
OF THE SENIOR NOTES) OCCURS, ADDITIONAL INTEREST WILL ACCRUE ON THIS SENIOR NOTE
AT A RATE OF 0.50% PER ANNUM (INCREASING BY AN ADDITIONAL 0.50% PER ANNUM AFTER
EACH CONSECUTIVE 90-DAY PERIOD THAT OCCURS AFTER THE DATE ON WHICH SUCH
REGISTRATION DEFAULT OCCURS, UP TO A MAXIMUM ADDITIONAL INTEREST RATE OF 1.0%)
FROM AND INCLUDING THE DATE ON WHICH ANY SUCH REGISTRATION DEFAULT SHALL OCCUR
TO BUT EXCLUDING THE DATE ON WHICH ALL REGISTRATION DEFAULTS HAVE BEEN
CURED.](1) The interest rate on the Senior Notes will in no event be higher than
the maximum rate

----------
(1) Insert if at the date of issuance of the Exchange Security any Registration
Default has occurred with respect to the related Initial Securities during the
interest period in which such date of issuance occurs.

                                                                               5

permitted by New York law as the same may be modified by United States law of
general application.

2.   METHOD OF PAYMENT

          The Issuers will pay interest on the Senior Notes (except defaulted
interest) to the Persons who are registered holders of Senior Notes at the close
of business on the January 1, April 1, July 1 or October 1 next preceding the
interest payment date even if Senior Notes are canceled after the record date
and on or before the interest payment date. Holders must surrender Senior Notes
to a Paying Agent to collect principal payments. The Issuers will pay principal
and interest in money of the United States that at the time of payment is legal
tender for payment of public and private debts. Payments in respect of the
Senior Notes represented by a Global Security (including principal, premium and
interest) will be made by wire transfer of immediately available funds to the
accounts specified by the Depository. The Issuers will make all payments in
respect of a certificated Security (including principal, premium and interest)
by mailing a check to the registered address of each Holder thereof; PROVIDED,
HOWEVER, that payments on a certificated Security will be made by wire transfer
to a U.S. dollar account maintained by the payee with a bank in the United
States if such Holder elects payment by wire transfer by giving written notice
to the Trustee or the Paying Agent to such effect designating such account no
later than 30 days immediately preceding the relevant due date for payment (or
such other date as the Trustee may accept in its discretion).

3.   PAYING AGENT AND REGISTRAR

          Initially, U.S. Bank National Association, a national banking
association (the "Trustee"), will act as Paying Agent and Registrar. The Issuers
may appoint and change any Paying Agent, Registrar or co-registrar without
notice. The Issuers or any of their domestically incorporated Wholly Owned
Subsidiaries may act as Paying Agent, Registrar or co-registrar.

4.   INDENTURE

          The Issuers issued the Senior Notes under an Indenture dated as of
October 29, 2004 ("Indenture"), among the Issuers, the Note Guarantors and the
Trustee. The terms of the Senior Notes include those stated in the Indenture and
those made part of the Indenture by reference to the Trust Indenture Act of 1939
(15 U.S.C. Sections 77aaa-77bbbb) (the "Act"). Terms defined in the Indenture
and not defined herein have the meanings ascribed thereto in the Indenture. The
Senior Notes are subject to all such terms, and Securityholders are referred to
the Indenture and the Act for a statement of those terms.

          The Senior Notes are general unsecured obligations of the Issuers. The
Issuers shall be entitled, subject to their compliance with Section 4.03 of the
Indenture, to issue Additional Senior Notes pursuant to Section 2.13 of the
Indenture. The Initial Senior Notes issued on the Issue Date, any Additional
Senior Notes and all Senior Exchange Notes issued in exchange therefor will be
treated as a single class for all

<Page>

                                                                               6

purposes under the Indenture. The Indenture contains covenants that limit the
ability of Boise Holdings, Timber Holdings, the Issuers and the other Restricted
Subsidiaries of Boise Holdings and Timber Holdings to incur additional
indebtedness; pay dividends or distributions on, or redeem or repurchase capital
stock; make investments; engage in transactions with affiliates; transfer or
sell assets; guarantee indebtedness; restrict dividends or other payments of
subsidiaries; consolidate, merge or transfer all or substantially all of their
assets and the assets of their subsidiaries; incur liens; and engage in
sale/leaseback transactions. These covenants are subject to important exceptions
and qualifications.

5.   OPTIONAL REDEMPTION

          The Issuers shall be entitled at their option at any time and from
time to time to redeem all or a portion of the Senior Notes upon not less than
30 nor more than 60 days' notice, at the redemption prices (expressed in
percentages of principal amount on the redemption date), plus accrued interest
to the redemption date (subject to the right of Holders of record on the
relevant record date to receive interest due on the relevant interest payment
date), if redeemed during the 12-month period commencing on October 15 of the

                  2007 and thereafter                100.000%

6.   NOTICE OF REDEMPTION

          Notice of redemption will be mailed at least 30 days but not more than
60 days before the redemption date to each Holder of Senior Notes to be redeemed
at his registered address. Senior Notes in denominations larger than $1,000
principal amount may be redeemed in part but only in whole multiples of $1,000.
If money sufficient to pay the redemption price of and accrued interest on all
Senior Notes (or portions thereof) to be redeemed on the redemption date is
deposited with the Paying Agent on or before the redemption date and certain
other conditions are satisfied, on and after such date interest ceases to accrue
on such Senior Notes (or such portions thereof) called for redemption.

7.   PUT PROVISIONS

          Upon a Change of Control, any Holder of Senior Notes will have the
right to cause the Issuers to repurchase all or any part of the Senior Notes of
such Holder at a repurchase price equal to 101% of the principal amount of the
Senior Notes to be repurchased plus accrued interest to the date of repurchase
(subject to the right of holders

                                                                               7

of record on the relevant record date to receive interest due on the related
interest payment date) as provided in, and subject to the terms of, the
Indenture.

8.   GUARANTY

          The payment by the Issuers of the principal of, and premium and
interest on, the Senior Notes is fully and unconditionally guaranteed on a joint
and several senior basis by each of the Note Guarantors to the extent set forth
in the Indenture.

9.   DENOMINATIONS; TRANSFER; EXCHANGE

          The Senior Notes are in registered form without coupons in
denominations of $2,000 principal amount and integral multiples of $1,000. A
Holder may transfer or exchange Senior Notes in accordance with the Indenture.
The Registrar may require a Holder, among other things, to furnish appropriate
endorsements or transfer documents and to pay any taxes and fees required by law
or permitted by the Indenture. The Registrar need not register the transfer of
or exchange any Senior Notes selected for redemption (except, in the case of a
Senior Note to be redeemed in part, the portion of the Senior Note not to be
redeemed) or any Senior Notes for a period of 15 days before a selection of
Senior Notes to be redeemed or 15 days before an interest payment date.

10.  PERSONS DEEMED OWNERS

          The registered Holder of this Senior Note may be treated as the owner
of it for all purposes.

11.  UNCLAIMED MONEY

          If money for the payment of principal or interest remains unclaimed
for two years, the Trustee or Paying Agent shall pay the money back to the
Issuers at their request unless an abandoned property law designates another
Person. After any such payment, Holders entitled to the money must look only to
the Issuers and not to the Trustee for payment.

12.  AMENDMENT, WAIVER

          Subject to certain exceptions set forth in the Indenture, (a) the
Indenture and the Senior Notes may be amended with the written consent of the
Holders of at least a majority in principal amount outstanding of the Senior
Notes and (b) any default or noncompliance with any provision may be waived with
the written consent of the Holders of a majority in principal amount outstanding
of the Senior Notes. Subject to certain exceptions set forth in the Indenture,
without the consent of any Holder of Senior Notes, the Issuers, the Note
Guarantors and the Trustee shall be entitled to amend the Indenture with respect
to the Senior Notes or the Senior Notes to cure any ambiguity, omission, defect
or inconsistency, or to comply with Article 5 of the Indenture, or to provide
for uncertificated Securities in addition to or in place of certificated
Securities, or to add guarantees with respect to the Senior Notes, including
Note Guaranties, or to secure the Senior Notes, or to add additional covenants
or surrender rights and powers

<Page>

                                                                               8

conferred on the Issuers or the Note Guarantors, or to comply with any
requirement of the SEC in connection with qualifying the Indenture under the
Act, or to make any change that does not adversely affect the rights of any
Holder of Senior Notes, or to make amendments to provisions of the Indenture
relating to the form, authentication, transfer and legending of the Senior
Notes.

13.  DEFAULTS AND REMEDIES

          Under the Indenture, Events of Default include (a) default for 30 days
in payment of interest on the Senior Notes; (b) default in payment of principal
on the Senior Notes at maturity, upon redemption pursuant to paragraph 5 of the
Senior Notes, upon acceleration or otherwise, or failure by the Issuers to
purchase Senior Notes when required; (c) failure by the Issuers or any Note
Guarantor to comply with other agreements in the Indenture or the Senior Notes,
in certain cases subject to notice and lapse of time; (d) certain accelerations
(including failure to pay within any grace period after final maturity) of other
Indebtedness of the Issuers if the amount accelerated (or so unpaid) exceeds $25
million; (e) certain events of bankruptcy or insolvency with respect to the
Issuers, Boise Holdings, Timber Holdings and the Significant Subsidiaries; (f)
certain judgments or decrees for the payment of money in excess of $25 million;
and (g) certain defaults with respect to Note Guaranties. If an Event of Default
occurs and is continuing, the Trustee or the Holders of at least 25% in
principal amount of the Senior Notes may declare all the Senior Notes to be due
and payable immediately. Certain events of bankruptcy or insolvency are Events
of Default which will result in the Senior Notes being due and payable
immediately upon the occurrence of such Events of Default.

          Securityholders may not enforce the Indenture or the Senior Notes
except as provided in the Indenture. The Trustee may refuse to enforce the
Indenture or the Senior Notes unless it receives indemnity or security
satisfactory to it. Subject to certain limitations, Holders of a majority in
principal amount of the Senior Notes may direct the Trustee in its exercise of
any trust or power. The Trustee may withhold from Securityholders notice of any
continuing Default (except a Default in payment of principal or interest) if it
determines that withholding notice is in the interest of the Holders.

14.  TRUSTEE DEALINGS WITH THE ISSUERS

          Subject to certain limitations imposed by the Act, the Trustee under
the Indenture, in its individual or any other capacity, may become the owner or
pledgee of Senior Notes and may otherwise deal with and collect obligations owed
to it by the Issuers or their Affiliates and may otherwise deal with the Issuers
or their Affiliates with the same rights it would have if it were not Trustee.

15.  NO RECOURSE AGAINST OTHERS

          A director, officer, employee or stockholder, as such, of the Issuers
or the Trustee shall not have any liability for any obligations of the Issuers
under the Securities or the Indenture or for any claim based on, in respect of
or by reason of such obligations

<Page>

                                                                               9

or their creation. By accepting a Security, each Securityholder waives and
releases all such liability. The waiver and release are part of the
consideration for the issue of the Securities.

16.  AUTHENTICATION

          This Security shall not be valid until an authorized signatory of the
Trustee (or an authenticating agent) manually signs the certificate of
authentication on the other side of this Security.

entireties), JT TEN (=joint tenants with rights of survivorship and not as
tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors
Act).

18.  CUSIP NUMBERS

Security Identification Procedures the Issuers have caused CUSIP numbers to be
printed on the Senior Notes and have directed the Trustee to use CUSIP numbers
in notices of redemption as a convenience to Securityholders. No representation
is made as to the accuracy of such numbers either as printed on the Senior Notes
or as contained in any notice of redemption and reliance may be placed only on
the other identification numbers placed thereon.

           [FORM OF REVERSE SIDE OF SENIOR SUBORDINATED EXCHANGE NOTE]

                    7-1/8% Senior Subordinated Note due 2014

1.   INTEREST

          Boise Cascade, L.L.C., a Delaware limited liability company, and Boise
Cascade Finance Corporation, a Delaware corporation (together, and with their
successors and assigns under the Indenture hereinafter referred to, the
"Issuers"), promise to pay interest on the principal amount of this Senior
Subordinated Note at the rate per annum shown above[; PROVIDED, HOWEVER, THAT IF
A REGISTRATION DEFAULT (AS DEFINED IN THE REGISTRATION RIGHTS AGREEMENT IN
RESPECT OF THE SENIOR SUBORDINATED NOTES) OCCURS, ADDITIONAL INTEREST WILL
ACCRUE ON THIS SENIOR SUBORDINATED NOTE AT A RATE OF 0.50% PER ANNUM (INCREASING
BY AN ADDITIONAL 0.50% PER ANNUM AFTER EACH CONSECUTIVE 90-DAY PERIOD THAT
OCCURS AFTER THE DATE ON WHICH SUCH REGISTRATION DEFAULT OCCURS UP TO A MAXIMUM
ADDITIONAL INTEREST RATE OF 1.0%) FROM AND INCLUDING THE DATE ON WHICH ANY SUCH
REGISTRATION DEFAULT SHALL OCCUR TO BUT EXCLUDING THE DATE ON WHICH ALL
REGISTRATION DEFAULTS HAVE BEEN CURED.](1) The Issuers will pay interest
semiannually in arrears on April 15 and October 15 of each year, commencing
April 15, 2005. Interest on the Senior Subordinated Notes will accrue from the
most recent date to which interest has been paid or, if no interest has been
paid, from October 29, 2004. Interest will be computed on the basis of a 360-day
year of twelve 30-day months. The Issuers will pay interest on overdue principal
at the rate borne by this Senior Subordinated Note plus 1.0% per annum, and will
pay interest on overdue installments of interest at the same rate to the extent
lawful.

2.   METHOD OF PAYMENT

          The Issuers will pay interest on the Senior Subordinated Notes (except
defaulted interest) to the Persons who are registered holders of Senior
Subordinated Notes at the close of business on the April 1 or October 1 next
preceding the interest payment date even if Senior Subordinated Notes are
canceled after the record date and on or before the interest payment date.
Holders must surrender Senior Subordinated Notes to a Paying Agent to collect
principal payments. The Issuers will pay principal and interest in money of the
United States that at the time of payment is legal tender for payment of public
and private debts. Payments in respect of the Senior Subordinated Notes
represented by a Global Security (including principal, premium and interest)
will be made by wire transfer of immediately available funds to the accounts
specified by the Depository. The Issuers will make all payments in respect of a
certificated Security (including principal, premium and interest) by mailing a
check to the registered address of each Holder thereof; PROVIDED, HOWEVER, that
payments on a certificated Security will be made by wire transfer to a U.S.
dollar account maintained by the payee with a bank in the United States if such
Holder elects payment by wire transfer by giving written notice

----------
(1)Insert if at the date of issuance of the Exchange Security any Registration
Default has occurred with respect to the related Initial Securities during the
interest period in which such date of issuance occurs.

                                                                               5

to the Trustee or the Paying Agent to such effect designating such account no
later than 30 days immediately preceding the relevant due date for payment (or
such other date as the Trustee may accept in its discretion).

3.   PAYING AGENT AND REGISTRAR

          Initially, U.S. Bank National Association, a national banking
association (the "Trustee"), will act as Paying Agent and Registrar. The Issuers
may appoint and change any Paying Agent, Registrar or co-registrar without
notice. The Issuers or any of their domestically incorporated Wholly Owned
Subsidiaries may act as Paying Agent, Registrar or co-registrar.

4.   INDENTURE

          The Issuers issued the Senior Subordinated Notes under an Indenture
dated as of October 29, 2004 ("Indenture"), among the Issuers, the Note
Guarantors and the Trustee. The terms of the Senior Subordinated Notes include
those stated in the Indenture and those made part of the Indenture by reference
to the Trust Indenture Act of 1939 (15 U.S.C. Sections 77aaa-77bbbb) (the
"Act"). Terms defined in the Indenture and not defined herein have the meanings
ascribed thereto in the Indenture. The Senior Subordinated Notes are subject to
all such terms, and Securityholders are referred to the Indenture and the Act
for a statement of those terms.

          The Senior Subordinated Notes are general unsecured obligations of the
Issuers. The Issuers shall be entitled, subject to their compliance with Section
4.03 of the Indenture, to issue Additional Senior Subordinated Notes pursuant to
Section 2.13 of the Indenture. The Initial Senior Subordinated Notes issued on
the Issue Date, any Additional Senior Subordinated Notes and all Senior
Subordinated Exchange Notes issued in exchange therefor will be treated as a
single class for all purposes under the Indenture. The Indenture contains
covenants that limit the ability of Boise Holdings, Timber Holdings, the Issuers
and the other Restricted Subsidiaries of Boise Holdings and Timber Holdings to
incur additional indebtedness; pay dividends or distributions on, or redeem or
repurchase capital stock; make investments; engage in transactions with
affiliates; transfer or sell assets; guarantee indebtedness; restrict dividends
or other payments of subsidiaries; and consolidate, merge or transfer all or
substantially all of their assets and the assets of their subsidiaries. These
covenants are subject to important exceptions and qualifications.

5.   OPTIONAL REDEMPTION

          Except as set forth below, the Issuers shall not be entitled to redeem
the Senior Subordinated Notes.

          On and after October 15, 2009, the Issuers shall be entitled at their
option (subject to their compliance with Section 4.04 of the Indenture) to
redeem all or a portion of the Senior Subordinated Notes upon not less than 30
nor more than 60 days' notice, at the redemption prices (expressed in
percentages of principal amount on the redemption date), plus accrued interest

each such redemption occurs within 90 days after the date of the related Equity
Offering.

          In addition, prior to October 15, 2007, the Issuers shall be entitled,

Additional Senior Subordinated Notes, if any) plus the applicable Make-Whole
Amount (as defined in the Indenture) as of the redemption date, if any, and
accrued and unpaid interest to the redemption date (subject to the right of
Holders on the relevant record date to receive interest due on the relevant
interest payment date). The Issuers shall cause notice of such redemption to be
mailed by first-class mail to each Holder's registered address, not less than 30
nor more than 60 days prior to the redemption date.

6.   NOTICE OF REDEMPTION

          Notice of redemption will be mailed at least 30 days but not more than
60 days before the redemption date to each Holder of Senior Subordinated Notes
to be redeemed at his registered address. Senior Subordinated Notes in
denominations larger than $1,000 principal amount may be redeemed in part but

the relevant record date to receive interest due on the related interest payment
date) as provided in, and subject to the terms of, the Indenture.

8.   GUARANTY

guaranteed on a joint and several senior subordinated basis by each of the Note
Guarantors to the extent set forth in the Indenture.

9.   SUBORDINATION

                                                                               8

Indenture and authorizes the Trustee to give it effect and appoints the Trustee

10.  DENOMINATIONS; TRANSFER; EXCHANGE

in denominations of $2,000 principal amount and integral multiples of $1,000. A
Holder may transfer or exchange Senior Subordinated Notes in accordance with the
Indenture. The Registrar may require a Holder, among other things, to furnish
appropriate endorsements or transfer documents and to pay any taxes and fees
required by law or permitted by the Indenture. The Registrar need not register
the transfer of or exchange any Senior Subordinated Notes selected for
redemption (except, in the case of a Senior Subordinated Note to be redeemed in
part, the portion of the Senior Subordinated Note not to be redeemed) or any
Senior Subordinated Notes for a period of 15 days before a selection of Senior
Subordinated Notes to be redeemed or 15 days before an interest payment date.

11.  PERSONS DEEMED OWNERS

          The registered Holder of this Senior Subordinated Note may be treated
as the owner of it for all purposes.

12.  UNCLAIMED MONEY

          If money for the payment of principal or interest remains unclaimed
for two years, the Trustee or Paying Agent shall pay the money back to the
Issuers at their request unless an abandoned property law designates another
Person. After any such payment, Holders entitled to the money must look only to
the Issuers and not to the Trustee for payment.

13.  DISCHARGE AND DEFEASANCE

          Subject to certain conditions, the Issuers at any time shall be
entitled to terminate some or all of their obligations under the Senior
Subordinated Notes and the Indenture if the Issuers deposit with the Trustee
money or U.S. Government Obligations for the payment of principal and interest
on the Senior Subordinated Notes to redemption or maturity, as the case may be.

14.  AMENDMENT, WAIVER

          Subject to certain exceptions set forth in the Indenture, (a) the
Indenture and the Senior Subordinated Notes may be amended with the written
consent of the Holders of at least a majority in principal amount outstanding of

of Senior Subordinated Notes, the Issuers, the Note Guarantors and the Trustee
shall be entitled to amend the Indenture with respect to the Senior

Subordinated Notes or the Senior Subordinated Notes to cure any ambiguity,
omission, defect or inconsistency, or to comply with Article 5 of the Indenture,
or to provide for uncertificated Securities in addition to or in place of
certificated Securities, or to add guarantees with respect to the Senior
Subordinated Notes, including Note Guaranties, or to secure the Senior
Subordinated Notes, or to add additional covenants or surrender rights and
powers conferred on the Issuers or the Note Guarantors, or to comply with any
requirement of the SEC in connection with qualifying the Indenture under the
Act, or to make any change that does not adversely affect the rights of any
Holder of Senior Subordinated Notes, or to make amendments to provisions of the
Indenture relating to the form, authentication, transfer and legending of the
Senior Subordinated Notes.

15.  DEFAULTS AND REMEDIES

          Under the Indenture, Events of Default include (a) default for 30 days
in payment of interest on the Senior Subordinated Notes; (b) default in payment
of principal on the Senior Subordinated Notes at maturity, upon redemption
pursuant to paragraph 5 of the Senior Subordinated Notes, upon acceleration or
otherwise, or failure by the Issuers to purchase Senior Subordinated Notes when
required; (c) failure by the Issuers or any Note Guarantor to comply with other
agreements in the Indenture or the Senior Subordinated Notes, in certain cases
subject to notice and lapse of time; (d) certain accelerations (including
failure to pay within any grace period after final maturity) of other
Indebtedness of the Issuers if the amount accelerated (or so unpaid) exceeds $25
million; (e) certain events of bankruptcy or insolvency with respect to the
Issuers, Boise Holdings, Timber Holdings and the Significant Subsidiaries; (f)
certain judgments or decrees for the payment of money in excess of $25 million;
and (g) certain defaults with respect to Note Guaranties. If an Event of Default
occurs and is continuing, the Trustee or the Holders of at least 25% in
principal amount of the Senior Subordinated Notes may declare all the Senior
Subordinated Notes to be due and payable immediately. Certain events of
bankruptcy or insolvency are Events of Default which will result in the Senior
Subordinated Notes being due and payable immediately upon the occurrence of such
Events of Default.

          Securityholders may not enforce the Indenture or the Senior
Subordinated Notes except as provided in the Indenture. The Trustee may refuse
to enforce the Indenture or the Senior Subordinated Notes unless it receives
indemnity or security satisfactory to it. Subject to certain limitations,
Holders of a majority in principal amount of the Senior Subordinated Notes may
direct the Trustee in its exercise of any trust or power. The Trustee may
withhold from Securityholders notice of any continuing Default (except a Default
in payment of principal or interest) if it determines that withholding notice is
in the interest of the Holders.

16.  TRUSTEE DEALINGS WITH THE ISSUERS

          Subject to certain limitations imposed by the Act, the Trustee under
the Indenture, in its individual or any other capacity, may become the owner or
pledgee of Senior Subordinated Notes and may otherwise deal with and collect
obligations owed to

                                                                              10

it by the Issuers or their Affiliates and may otherwise deal with the Issuers or
their Affiliates with the same rights it would have if it were not Trustee.

17.  NO RECOURSE AGAINST OTHERS

          A director, officer, employee or stockholder, as such, of the Issuers
or the Trustee shall not have any liability for any obligations of the Issuers
under the Securities or the Indenture or for any claim based on, in respect of
or by reason of such obligations or their creation. By accepting a Security,
each Securityholder waives and releases all such liability. The waiver and
release are part of the consideration for the issue of the Securities.

18.  AUTHENTICATION

          This Security shall not be valid until an authorized signatory of the
Trustee (or an authenticating agent) manually signs the certificate of
authentication on the other side of this Security.

entireties), JT TEN (=joint tenants with rights of survivorship and not as
tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors
Act).

20.  CUSIP NUMBERS

          Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures the Issuers have caused CUSIP numbers to be
printed on the Senior Subordinated Notes and have directed the Trustee to use
CUSIP numbers in notices of redemption as a convenience to Securityholders. No
representation is made as to the accuracy of such numbers either as printed on
the Senior Subordinated Notes or as contained in any notice of redemption and
reliance may be placed only on the other identification numbers placed thereon.

     Upon transfer, the Securities would be registered in the name of the new

Name:________________________

Address:______________________

Taxpayer ID Number:____________

     The undersigned represents and warrants to you that:

     1. We are an institutional "accredited investor" (as defined in Rule
501(a)(1), (2), (3) or (7) under the Securities Act of 1933, as amended (the
"Securities Act")), purchasing for our own account or for the account of such an
institutional "accredited investor" at least $250,000 principal amount of the
Securities, and we are acquiring the Securities not with a view to, or for offer
or sale in connection with, any distribution in violation of the Securities Act.
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 invest in or purchase securities similar to the Securities in the normal
course of our business. We, and any accounts for which we are acting, are each
able to bear the economic risk of our or its investment.

     2. We understand that the Securities have not been registered under the
Securities Act and, unless so registered, may not be sold 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

                                                                               2

the date that is two years after the later of the date of original issue and the
last date on which the Issuers were or any affiliate of the Issuers was the
owner of such Securities (or any predecessor thereto) (the "Resale Restriction
Termination Date") only (i) to the Issuers, (ii) in the United States to a
person whom the seller reasonably believes is a qualified institutional buyer in
a transaction meeting the requirements of Rule 144A, (iii) to an institutional
"accredited investor" within the meaning of Rule 501(a)(1), (2), (3) or (7)
under the Securities Act that is an institutional accredited investor purchasing
for its own account or for the account of an institutional accredited investor,
in each case in a minimum principal amount of the Securities of $250,000, (iv)
outside the United States in a transaction complying with the provisions of Rule
904 under the Securities Act, (v) pursuant to an exemption from registration
under the Securities Act provided by Rule 144 (if available) or (vi) pursuant to
an effective registration statement under the Securities Act, in each of cases
(i) through (vi), subject 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 in 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 (iii) 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 Issuers and
the Trustee, which shall provide, among other things, that the transferee is an
institutional "accredited investor" within the meaning of Rule 501(a)(1), (2),
(3) or (7) under the Securities Act and that it is acquiring such Securities for
investment purposes and not for distribution in violation of the Securities Act.
Each purchaser acknowledges that the Issuers and the Trustee reserve the right
prior to the offer, sale or other transfer prior to the Resale Restriction
Termination Date of the Securities pursuant to clause (iii), (iv) or (v) above
to require the delivery of an opinion of counsel, certifications or other
information satisfactory to the Issuers and the Trustee.
