        reason of the cessation of the liability of any other Borrower from any
        cause other than indefeasible payment in full of all of the Obligations;

                (j) Any defense based upon any statute or rule of law that
        provides that the obligation of a surety must be neither larger in
        amount nor in other respects more burdensome than that of the principal;

                (k) Any defense based upon the Lenders' acts or omissions in the
        administration of the Obligations, including any act or omission that
        directly or indirectly results in or contributes to the discharge of any
        of the Obligations, except behavior that amounts to bad faith;

                (l) Any principles or provisions of law, statutory or otherwise,
        that are or might be in conflict with the terms of this Agreement, and
        any legal or equitable discharge of such Borrower's obligations under
        this Agreement;

                (m) The benefit of any statute of limitations affecting such
        Borrower's liability under this Agreement or the enforcement of this
        Agreement;

                (n) Any rights to set-offs, recoupments, and counterclaims;

                (o) Any requirement that the Lenders protect, secure, perfect or
        insure any security interest or lien or any property subject to such
        interest or lien;

                (p) Notices (including any notice required under Section 9-504
        of the Uniform Commercial Code of the State of Washington), demands,
        presentments, protests, notices of protest, notices of dishonor and
        notices of any action or inaction, including acceptance of this
        Agreement, notices of default under any of the documents executed in
        connection with this Agreement, notices of any renewal, extension or
        modification of the Obligations or any agreement related to the
        Obligations, notices of any extension of credit to any other Borrower,
        and any right to consent to any of such matters; and

                (q) To the fullest extent permitted by law, any defenses or
        benefits that may be derived from or afforded by law that limit the
        liability of or exonerate guarantors or sureties, or that may conflict
        with the terms of this Agreement.

                Notwithstanding any other provision of this Agreement, each
        Borrower affirms that it signs this Agreement as a principal, and not as
        surety, guarantor, or accommodation party.

        21. In the first sentence of Section 11.7(b) of the Existing Credit
Agreement, part (i) is amended to read as follows:

                (i) such assignment, if not to a Lender or an Affiliate of the
        assigning Lender, shall be consented to by Trendwest at all time other
        than during the existence of an Default or Event of Default and by the
        Administrative Agent (which approval of Trendwest shall not be
        unreasonably withheld or delayed),

The following sentence is added as the second sentence of Section 11.7(b):



                                     - 8 -
<PAGE>   10

        Notwithstanding the foregoing, (x) during the existence of a Default or
        an Event of Default, a Lender shall not be required to obtain the
        consent of any other Person with respect to an assignment of its
        interest under this Credit Agreement; and (y) a Lender may at any time
        pledge or assign all or any part of (or a proportionate participating
        interest in) such Lender's rights under this Credit Agreement and all
        documents executed in connection herewith to any Federal Reserve Bank in
        accordance with applicable laws.

The following sentence (the existing second sentence) of Section 11.7(b) is
amended to read as follows:

        Upon obtaining any consent required as set forth in the first sentence
        of this Section 11.7(b), any forms required by Section 11.8 and payment
        of the requisite fee described below, the assignee named in the
        Assignment and Acceptance shall be a Lender for all purposes of this
        Agreement to the extent of the Assigned Interest, and the assigning
        Lender shall be released from any further obligations under this
        Agreement to the extent of such Assigned Interest.

        22. That portion of Section 11.13 of the Existing Credit Agreement that
appears before the words "provided, however," is amended to read as follows:
"Any term of this Agreement or of the Revolving Notes may be amended and the
observance of any term of this agreement or of the Revolving Notes may be waived
(either generally or in a particular instance and either retroactively or
prospectively) only with the written consent of the Borrowers and at least
two-thirds (2/3) of the Lenders;".

        23. Schedule 1 to the Existing Credit Agreement is hereby deleted, and
Schedule 1 to this Second Amendment is substituted in its place.

        24. Exhibit C to the Existing Credit Agreement is hereby deleted, and
Exhibit C to this Second Amendment is substituted in its place.

        25. As partial consideration for the Requested Modifications, the
Borrowers represent and warrant to the Lender Parties as follows:

                (a) Corporate Authority; Conflict. The execution, delivery and
performance by the Borrowers of this Second Amendment are within the Borrowers'
corporate powers, have been duly authorized by all necessary corporate action,
and require no action or consent by or in respect of, or filing with, any
governmental body, agency, official or any other person or entity, and the
execution, delivery and performance by the Borrowers of this Second Amendment do
not contravene, or constitute a default under, any provision of applicable law
or regulations or of the certificate or articles of incorporation or the bylaws
of the Borrowers or any of their Subsidiaries or any material agreement,
judgment, injunction, order, decree or other instrument binding upon the
Borrowers or any of their Subsidiaries.

                (b) Enforceability. This Second Amendment constitutes the valid
and binding obligations of the Borrowers, enforceable against the Borrowers in
accordance with their terms, except as enforceability may be subject to
applicable bankruptcy, insolvency, reorganization, moratorium or other similar
laws now or hereafter in effect relating to creditors' remedies, and to general
principles of equity (regardless of whether enforcement is sought in a
proceeding in equity or at law).



                                     - 9 -
<PAGE>   11

                (c) No Event of Default. No Possible Default or Event of Default
has occurred and is continuing, and the representations and warranties of the
Borrowers contained in the Existing Credit Agreement and the other documents
delivered pursuant to the Existing Credit Agreement true and correct in all
material respects as of the date of this Second Amendment as if made on the date
of this Second Amendment.

                (d) Possible Claims and Defenses. The Borrowers have no claims
or defenses against any person or entity that would or might affect (i) the
enforceability of any provisions of the Existing Credit Agreement, as modified
by this Second Amendment (collectively, the "Amended Credit Agreement"), or (ii)
the collectability of sums advanced by the Lender Parties pursuant to the
Existing Credit Agreement or the Amended Credit Agreement.

        26. The Lender Parties' obligations under this Second Amendment are
subject to satisfaction of the following conditions on or prior to the date on

                (b) Real Estate Matters.

                        (i) With respect to MountainStar, Trendwest shall cause

that comprise MountainStar, consisting of approximately 7,400 acres. Such deed
of trust is referred to in this Agreement as the "MountainStar Deed of Trust."
Trendwest shall cause Trendwest Investments to have paid all taxes, fees or
charges incurred in connection with the execution or recording of the
MountainStar Deed of Trust.

                        (ii) Trendwest shall cause Trendwest Investments to have
procured and delivered to the Administrative Agent a commitment from a title
insurance company satisfactory to the Agent for an ALTA mortgagee's policy of
title insurance (Form 1970 if available, or, if not, Form 1984 or 1990 with 1970
Endorsement) covering each parcel of real estate comprising MountainStar, which
policy shall (i) be issued in favor of the Administrative Agent, for the benefit
of the Lenders in accordance with their respective Ratable Shares, (ii) be
reasonably satisfactory to the Administrative Agent, and (iii) insure that the
MountainStar Deed of Trust is a valid first priority lien on the real property

Coverage Endorsement" insuring over the general exceptions contained customarily
in such policy, (C) contain an access endorsement in form satisfactory to the
Administrative Agent, and (D) contain a "contiguity" endorsement in form

present) with Environmental Laws by Trendwest or Trendwest Investments as any
Lender may reasonably request.

               (c) Guaranty. The Guaranty shall have been duly executed by

               (d) Hazardous Materials Indemnity. The Hazardous Materials
Indemnity shall have been duly executed by Trendwest Investments and delivered
to the Administrative Agent.

               (f) Resolutions. The Administrative Agent shall have received
certified copies of the resolutions of the Borrowers' Boards of Directors
approving the execution, delivery, and performance of this Second Amendment,
together with evidence of the authority and specimen signatures of the persons
who have signed the Second Amendment. The Administrative Agent shall have
received certified copies of the resolutions of the Board of Directors of
Trendwest Investments approving the execution, delivery and performance of the
Guaranty, the MountainStar Deed of Trust, the Hazardous Materials Indemnity and
the UCC-1 Financing Statement, and specimen signatures of the persons who have
signed such documents on behalf of Trendwest Investments.

               (g) Opinions of Counsel. The Administrative Agent shall have
received a legal opinion from Borrowers' counsel in form and substance
satisfactory to the Administrative Agent. The Administrative Agent shall also
have received a legal opinion from counsel to Trendwest Investments in form and
substance satisfactory to the Administrative Agent, opining as to the execution,
authorization and enforceability of the Guaranty, the MountainStar Deed of
Trust, the Hazardous Materials Indemnity and the UCC-1 Financing Statement.

               (h) Payment of Expenses. The Borrowers shall have reimbursed the
Lender Parties for all legal fees and expenses incurred by the Lender Parties in

correct.

               (j) Other Documents. The Lender parties shall have received such
other documents and instruments as they may reasonably request.

        27. Nothing in this Amendment will be construed to obligate the Lender

Credit Agreement, the Amended Credit Agreement or any other document.



                                     - 11 -
<PAGE>   13

        28. The Borrowers hereby acknowledge that they expect to receive no
further accommodations from the Lender Parties, and that this Second Amendment
will not be construed to create any course of dealing between the Borrowers and
the Lender Parties.

        29. Except as expressly set forth in this Second Amendment, the
execution, delivery, and performance of this Second Amendment will not operate
as a waiver or amendment of any right, power, or remedy of the Lender Parties or
the Borrowers under the Existing Credit Agreement or any related document.

        30. Except as otherwise expressly set forth in this Second Amendment,
all of the terms, conditions, and covenants of the Existing Credit Agreement
remain in full force and effect. ORAL AGREEMENTS OR ORAL COMMITMENTS TO LOAN
MONEY, TO EXTEND CREDIT, OR TO FORBEAR FROM ENFORCING REPAYMENT OF A DEBT ARE
NOT ENFORCEABLE UNDER WASHINGTON LAW.

        31. This Second Amendment may be executed and delivered in separate
counterparts, all of which taken together will constitute one and the same
instrument. Each party to this Second Amendment may accomplish such execution
and delivery by signing a counterpart of this Second Amendment and sending such
counterpart by facsimile to the other party. Upon the request of either party,
the other party will deliver an executed original of this Second Amendment,
provided, however, that the failure to deliver such original will not affect the
validity, enforceability, and/or binding effect of this Second Amendment.

        FOR VALUE RECEIVED, the undersigned promises to pay to the order of
JELD-Wen, inc., an Oregon corporation, at its office at 3250 Lakeport Boulevard,
Klamath Falls, OR 97601, or at such other place as the holder of this Note
(hereinafter, "holder") may from time to time designate in writing, the sum of
Seventeen Million Seven Hundred Thirty-One Thousand and NO/100 Dollars
($17,731,000.00) in lawful money of the United States, with interest thereon
from the date of this Note until paid at the rate set forth below, computed on
monthly balances. Interest for each full calendar month during the term of this
Note shall be calculated on the basis of a 360-day year and twelve 30-day
months. Interest for any partial calendar month at the beginning of the term of
this Note shall be calculated on the basis of a 360-day year and the actual
number of days in that month. Interest for any partial calendar month at the end
of the term of this Note shall be calculated on the basis of a 365- or 366-day
year and the actual number of days in that month.

        1.      Interest Rate.

        The per annum interest rate hereunder (the "Note Rate") shall be nine
percent (9%).

        2.      Payments.

        Payments will be made on the schedule attached hereto as Exhibit 1.

        3.      Maturity.

        Unless sooner repaid by Borrower, the entire unpaid principal balance of
this Note, plus all accrued but unpaid interest, and all other amounts owing
hereunder shall be due and payable in full on June 1, 2003 (the "Maturity
Date").

        4.      Application of Payments.

interest; (ii) second, to the reduction of principal of this Note.

        6.      Late Charge.

        If any amount payable hereunder is paid more than ten (10) days after
the due date thereof, Borrower promises to pay a late charge of five percent
(5%) of the delinquent amount as liquidated damages for the extra expense in
handling past due payments.

        7.      Default; Remedies.

        If default is made in the payment of any amount payable hereunder when
due, then, at the option of holder, the entire indebtedness evidenced hereby
shall become immediately due and payable. Upon default, and without notice or
demand, all amounts owed under this Note, including all accrued but unpaid
interest, shall thereafter bear interest at the rate of five percent (5%) per
annum above the Note Rate (the "Default Rate") until such default is cured.
Failure to exercise any option granted to holder hereunder shall not waive the
right to exercise the same in the event of any subsequent default. Interest at
the Default Rate shall commence to accrue upon default under this Note,
including the failure to pay this Note at maturity.

        8.      Attorney Fees.

        In the event of any default under this Note, or in the event that any
dispute arises relating to the interpretation, enforcement or performance o this
Note, holder shall be entitled to collect from Borrower on demand all fees and
expenses incurred in connection therewith, including but not limited to fees of
attorneys, accountants, appraisers, environmental inspectors, consultants,
expert witnesses, arbitrators, mediators, and court reporters. Without limiting
the generality of the foregoing, Borrower shall pay all such costs and expenses
incurred in connection with (a) arbitration or other alternative dispute
resolution proceedings, trial court actions, and appeals; (b) bankruptcy or
other insolvency proceedings of Borrower, any guarantor or other party liable
for any of the obligations of this Note, or any party having any interest in any
security for any of those obligations; (c) judicial or nonjudicial foreclosure
