      THIS-LOAN AGREEMENT is made as of this 22nd day of October, 2004 by PG

      NOW, THEREFORE, in consideration of such loan and for other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, and intending to be legally bound hereby, Borrower and Lender
agree as follows:

                                    ARTICLE 2
             MAXIMUM LOAN AMOUT; PAYMENT TERMS; ADVANCES; DEFEASANCE

      2.01. Commitment to Lend.

      (a) Maximum Loan Amount Approved. Subject to the terms and conditions set
forth herein, and in reliance on Borrower's representations, warranties and
covenants set forth herein, Lender agrees to loan the Maximum Loan Amount to
Borrower. The Loan shall be evidenced by this Loan Agreement and by the Note
made by Borrower to the order of Lender and shall bear interest and be paid upon
the terms and conditions provided herein.

            (b) Advance of Maximum Loan Amount. On the Closing Date, Lender
shall advance the entire Maximum Loan Amount to Borrower.

      2.02. Calculation of Interest.

            (a) Calculation Basis. Interest due on the Loan shall be paid in
arrears and calculated based on a 360-day year and paid for the actual number of
days elapsed in such partial month by a daily rate calculated on said 360-day
year.

            (b) Applicable Interest Rate. Interest shall accrue on outstanding
principal at the rate of six and fourteen one hundredths percent (6.14%) per
annum ("APPLICABLE INTEREST RATE").

            (c) Adjustment for Impositions on Loan Payment. All payments made by
Borrower hereunder shall be made free and clear of, and without reduction for,
or on account of, any income, stamp or other taxes, levies, imposts, duties,
charges, fees, deductions or withholdings hereafter imposed, levied, collected,
withheld or assessed by and government or taxing authority (other than taxes on
the overall net income or overall gross receipts of Lender imposed as a result
of a present or former connection between Lender and the jurisdiction of the
government or taxing authority imposing same provided, that this exclusion shall
not apply to a government or taxing authority imposing same provided, that this
exclusion shall not apply to a connection arising solely from Lender's having
executed, delivered, performed its obligations

under, received a payment under, or enforced this Loan Agreement or any other
Loan Document). If any such amounts are required to be withheld from amounts
payable to lender, the amounts payable to lender under the Loan Documents shall
be increased to the extent necessary to yield to Lender, after payment of such
amounts, interest or any such other amounts payable at the rates or in the
amounts specified herein. If any such amounts are payable by Borrower, Borrower
shall pay all such amounts by their due date and promptly send Lender a
certified copy of an original official receipt showing payment thereof. If
Borrower fails to pay such amounts when due or to deliver the required receipt
to Lender, Borrower shall indemnify Lender for any incremental taxes, interest
or penalties that may become payable by Lender as a result of any such failure.

            (d) Intentionally Omitted.

            (e) Acceleration. Notwithstanding anything to the contrary contained
herein, if Borrower is prohibited by law from paying any amount due to Lender
under Section 2.02(c) or (d), Lender may elect to declare the unpaid principal
balance of the Loan, together with all unpaid interest accrued thereon and any
other amount due hereunder, due and payable within ninety (90)
days of Lender's written notice to Borrower. No prepayment Fee shall be due in
such event. Lender's delay or failure in accelerating the Loan upon the
discovery or occurrence of an event under Section 2.02(c) or (d) shall not be
deemed a waiver or estoppel against the exercise of such right.

      2.03. Payment of Principal and Interest.

            (a) Payment at Closing. If the Loan is funded on a date other than
the first (1st) day of a calendar month, Borrower shall pay to Lender at the
time of funding an interest payment calculated by multiplying (i) the number of
days from and including the date of funding to (but excluding) the first
(1st)day of the next calendar month by (ii) a daily rate based on the Applicable
Interest Rate and Calculated for a 360-day year.

            (b) Payment Dates. Commencing on the first (1st) day of December,
2004 and continuing on the first (1st) day of each and every successive month
thereafter (each, a "PAYMENT DUE DATE"), through and including the Payment Due
Date immediately prior to the Maturity date, Borrower shall pay consecutive
monthly payments of principal and interest in the amount of $127,879.75 and any
amounts due pursuant to Section 2.02 of this Loan Agreement.

            (c) Maturity Date. On the first (1st) day of November, 2024
("MATURITY DATE"), Borrower shall pay the entire outstanding principal balance
of the Loan, together with all accrued but unpaid interest thereon and all other
amounts due under this Loan Agreement, the Note or any other Loan Document.

                                                              Ply Gem Industries

\      2.04. Payments Generally.

            (a) Delivery of Payments. All payments due to Lender under this Loan
Agreement and the other Loan Documents are to be paid in immediately available
funds to Lender at Lender's office located at 200 Witmer Road, P.O. Box 809,
Horsham, Pennsylvania 19044, Attn: Servicing - Accounting Manager or by wire
transfer to Lender, or at such other Place as Lender may designate to Borrower
in writing from time to time. All amounts due under this loan Agreement and the
other Loan Documents shall be paid without setoff, counterclaim or any other
deduction whatsoever.

            (b) Credit for Payment Receipt. No payment due under this Loan
Agreement or any of the other Loan documents shall be deemed paid to Lender
until received by Lender at its designated office on a business day prior to
2:00 p.m. Eastern Standard Time. Any payment received after the time established
by the preceding sentence shall be deemed to have been paid on the immediately
following business day. Each payment that is paid to Lender in the calendar
month in which it is due, but prior to its scheduled Payment due date, shall not
be deemed a prepayment and shall be deemed to have been received on the payment
Due Date, solely for the purpose of calculating interest due. Where a Payment
Due Date falls on a date other than a business day, the Payment due date shall
be deemed the first business day immediately thereafter.

            (c) Invalidated Payments. If any payment received by Lender is
deemed by a court of competent Jurisdiction to be a voidable preference or
fraudulent Conveyance under any bankruptcy, insolvency or other debtor relief
law, and is required to be returned by Lender, then the obligation to make such
payment shall be reinstated, notwithstanding that the Note may have been marked
satisfied and returned to Borrower or otherwise canceled, and such payment shall
be immediately due and payable upon demand.

            (d) Late Charges. If any payment due on a Payment Due Date is not
received by Lender in full on or before the fifth (5th) day after the Payment
Due Date on which such payment is due (e.g., if the Payment Due Date is the 1st
day of month, a late charge would accrue if the full payment is not received on
or before the 5th day of the month), Borrower shall pay to Lender, immediately
and without demand, a late fee equal to five percent (5%) of such delinquent
amount.

            (e) Default Interest Rate. If the Loan is not paid in full on or
before the Maturity Date or if the Loan is accelerated following an event of
Default and during the continuance thereof, the interest rate then payable on
the Loan shall immediately increase to the Applicable Interest Rate plus five
hundred (500) basis points ("DEFAULT RATE") and continue to accrue at the
Default Rate until full payment is received. In addition, Lender shall have the
right, without acceleration of the Loan, to collect interest at the Default rate
on any payment due hereunder (including, without limitation, late charges and
fees for legal counsel) which is not received by Lender on or before the date on
which such payment originally was due. Interest at

                                     - 4 -
<PAGE>
the Default Rate also shall accrue on any judgment obtained by Lender in
connection with collection of the Loan or enforcement of any obligations due
under the other Loan Documents until such judgment amount is paid in full.

            (f) Application of Payments. Payments of principal and interest due
from Borrower shall be applied first to the payment of late fees, then to Lender
advances made to protect the Property or to perform obligations which Borrower
failed to perform, then to the payment of accrued but unpaid interest, and then
to reduction of the outstanding principal. If at any time Lender receives less
than the full amount due and payable on a Payment Due Date, Lender may apply the
amounts received to amounts then due and payable in any manner and in any order
determined by Lender, in its sole discretion. Following an Event of Default,
Lender may apply all payments to amounts then due in any manner and in any order
determined by Lender, in its sole discretion. Lender's acceptance of a payment
form Borrower in an amount that is less than the full amount then due and
Lender's application of such payments to amounts then due from Borrower shall
not constitute or be deemed to constitute a waiver of the unpaid amounts or an
accord and satisfaction. No principal amount repaid may be reborrowed.

     2.05.  Prepayment Rights.

            (a) Prepayment. Borrower acknowledges that Lender is making the
Loan to it at the interest rate and upon the other terms herein set forth in
reliance upon Borrower's promise to pay the Loan over the full stated term of
this Loan Agreement and that Lender may suffer loss or other detriment if
Borrower were to prepay all or any portion of the Note prior to its stated
Maturity Date. Except as provided in this Section 2.05 and Section 9.04(f) or
as otherwise provided in this Agreement, Borrower agrees that Borrower has no
right to prepay all or any part of the Loan prior to the Maturity Date. On and
after the first (1st) day of the third (3rd) month preceding the Maturity Date
(the "OPEN DATE"), Borrower may prepay the Loan in whole, but not in part,
provided Borrower pays with such prepayment (a) all accrued interest and all
other outstanding amounts then due and unpaid under this Loan Agreement and
under the other Loan Documents, and (b) if the prepayment is not made on a
Payment Due Date, Borrower pays with such prepayment the full interest amount
that would have accrued for the period from the date of prepayment through the
day prior to the next Payment Due Date. Lender is not obligated to accept any
prepayment unless accompanied by amounts required hereunder. Notwithstanding any
contrary provision of this Loan Agreement, Lender may at any time apply proceeds
from a casualty or condemnation to principal as provided in this Loan
Agreement, provided that any such application shall not be subject to any
prepayment due.

            (b)  Voluntary Defeasance of the Loan.

                  (i) Defeasance to Release Property from Security Instrument.
Subject to Borrower's compliance with all terms and conditions of this Section
2.05(b), Borrower may defease the Loan in whole, or in part as set forth in
Section 10.03, in the manner hereinafter set forth ("DEFEASANCE") on any
Business Day after the Lock-out Period Expiration Date (defined

                                                              Ply Gem Industries

                                     - 5 -
<PAGE>

below) and obtain a release ("RELEASE") of the Property or any one Property,
provided Borrower complies with section 10.03, from the lien of the Security
Instrument. Once a Defeasance in whole has been completed, the Loan will be
secured by the Defeasance Collateral (defined below), and thereafter the Loan
cannot be the subject of any further Defeasance nor prepaid in whole or in part,
notwithstanding any provision of this Section 2.05 to the contrary. Once partial
Defeasance has been completed, the Loan will be partially secured by the
Defeasance Collateral (defined below), and thereafter the portion of the Loan
defeased cannot be prepaid in whole or in part, notwithstanding any provision of
this Section 2.05 to the contrary. "LOCK-OUT PERIOD EXPIRATION DATE" means the
earlier to occur of (i) the third (3rd) anniversary of the Closing Date, or (ii)
the second (2nd) anniversary of the "startup date" of the REMIC within the
meaning of Section 860G(a)(9) of the Tax Code.

                  (ii) Condition to Defeasance. Borrower may cause a Release or
a Partial Release upon the satisfaction of the following conditions (all as
reasonably approved by Lender):

                        (A) no Event of Default shall exist under any of the
Loan Document;

                        (B) not less than forty-five (45) (but not more than
ninety (90)) days prior written notice shall be given to Lender specifying a
date (such date being on a Payment Due Date) on which the Defeasance Collateral
(as hereinafter defined) is to be delivered (the "RELEASE DATE");

                        (C) all accrued and unpaid interest and all other sums
due under the Note, this Loan Agreement and under the other Loan Documents up to
the Release Date including, without limitation, all fees, costs and expenses
incurred by Lender and its agents in connection with such release (including,
without limitation, reasonable legal fees and expenses for the review and
preparation of the Defeasance Pledge Agreement (as defined below) and of the
other materials described in Section 2.05(b)(ii)(D) below and any release
documentation, and any servicing fees, rating Agency fees or other costs related
to such release), shall be paid in full on or prior to the Release Date;

                        (D) Borrower shall deliver the following to Lender on or
prior to the Release Date:

                              (1) The Defeasance Collateral which meets all
requirements of subsection 2.05(b)(iii) below and is owned by Borrower, free and
clear of all liens and claims of third-parties.

                              (2) A written certification of an independent
certified public accounting firm (reasonably acceptable to Lender), confirming
that the Defeasance Collateral will (1) in the event of Defeasance of the entire
loan generate amounts sufficient to

                                                              Ply Gem Industries
                                     - 6 -
<PAGE>

make all Scheduled Debt Payments as they fall due under the Note, including full
payment due on the Note on the Maturity Date, or (2) in the event of partial
Defeasance, generate amounts sufficient to make scheduled Debt Payments as they
fall due under the Defeasance Note, including full payment on such Defeasance
Note on the Maturity Date.

                              (3) Lender's form of a pledge and security
agreement ("DEFEASANCE PLEDGE AGREEMENT") and financing statements which pledge
and create a first priority security interest in the Defeasance Collateral in
favor of Lender.

                              (4) Confirmation in writing from Lender's
custodian that it has received all of the Defeasance Collateral for the account
and benefit of Lender.

                              (5) A written certification from Borrower which
confirms that, following Defeasance, Borrower continues to satisfy the "single
purpose entity" requirements of this Loan Agreement.

                              (6) Such legal opinions given by Borrower's
counsel (which counsel must be reasonably acceptable to Lender) as Lender may
require to confirm (i) that the Defeasance Collateral and the proceeds thereof
have been validly pledged to Lender, that the Defeasance Pledge Agreement and
other Loan Documents after the Defeasance are enforceable against Borrower in
accordance with the respective terms and Lender has a perfected first priority
security interest in the Defeasance Collateral, (ii) the release of the lien of
the Security Instrument and the Pledge of Defeasance Collateral will not
directly or indirectly result in or cause any REMIC that then holds the Notes to
fail to maintain its status as a REMIC and(iii) the defeasance will not cause
any REMIC to be an investment company under the Investment company Act of 1940
and (iv) an opinion by Lender's counsel or counsel reasonably acceptable to
Lender at Borrower's expense in the event of a bankruptcy proceeding or similar
occurrence with respect to Borrower, none of the Defeasance Collateral nor any
proceeds thereof will be property of Borrower's estate under Section 541 of the
Bankruptcy Code or any similar statute and the grant of security interest
therein to Lender shall not constitute an avoidable preference under Section 547
of the Bankruptcy Code or applicable state law.

                              (7) Forms of all documents necessary to release
the Property or, in the case of partial defeasance, the Release Property from
the liens created by the security Instrument and related UCC financing
statements (collectively, "RELEASE INSTRUMENTS"), each in appropriate form
required by the state in which the Property or, in the case of partial
Defeasance, the Release Property is located.

                              (8) Such other certificates, confirmations,
documents or instruments as Lender reasonably deems necessary in connection with
the Defeasance, including, without limitation, a rating Confirmation.

                        (G) Borrower shall satisfy the requirements of Section
10.03 hereof.

                                                              Ply Gem Industries

                                     - 7 -
<PAGE>

                  (iii) Purchase and Ownership of the Defeasance Collateral. The
"DEFEASANCE COLLATERAL" must consist only of non-callable and non-redeemable
securities issued, or fully insured as to payment, by the United States of
America or such other securities as are permitted at the time of Defeasance by
the Tax Code with respect to REMIC collateral substitutions. The Defeasance
Collateral also must provide for (A) redemption payments to occur prior, but as
close as possible, to all successive Payment Due Dates Occurring after the
Release Date and (B) deliver redemption proceeds at least equal to (1) in the
event of Defeasance of the entire Loan the amount of principal and interest due
on the Note on each such Payment Due Date including full payment due on the Note
on the Maturity Date or (2) in the event of partial Defeasance the amount of
principal and interest due on the Defeased Not on each such Payment Due Date,
including full payment due on the Defeasance Note on the Maturity Date
("SCHEDULED DEBT PAYMENT"). The Defeasance collateral shall be arranged such
that redemption payments received from the Defeasance Collateral are paid
directly to Lender to be applied on account of the Scheduled Debt Payments.
Unless otherwise agreed in writing by Lender, the pledge of the Defeasance
Collateral shall be effectuated through the book-entry facilities of a qualified
securities intermediary designated by Lender (which may be Lender itself or an
affiliate of Lender if such party qualifies as a securities Intermediary) in
conformity with all applicable laws.

                  (iv) Successor Borrower Option. Borrower, at Borrower's
expense, has the right, or in the case of partial Defeasance, an obligation to
designate an accommodation borrower ("SUCCESSOR BORROWER") which satisfies
Lender's then current requirements for a "single purpose entity" to assume at
the time of Defeasance ownership of the Defeasance Collateral and liability for
all or, in the case of partial Defeasance, a portion of, related to the Partial
Release Price of Borrower's obligations under this Loan Agreement, the
Defeasance Pledge Agreement and the other Loan Documents (to the extent that
liability thereunder survives repayment of the Loan and release of the Property
or, in the case of partial Defeasance, the Release Property). Such transfer and
assumption shall be evidenced by a duly executed, Written agreement reasonably
satisfactory to Lender, whereupon Borrower (subject to satisfaction of all
requirements of this Section 2.05(b)(ii) shall be relieved, or, in the case of
partial Defeasance, Partially relieved from liability in connection with the
Loan (except for those obligations which, by the express terms of the Loan
Documents, survive payment of the Loan which shall be assumed by Successor
Borrower). Notwithstanding any contrary provision in this Loan Agreement, no
assumption fee is required upon a transfer of the Loan in accordance with this
Section. If a Successor Borrower assumes Borrower's obligations, Lender may
require as a condition to Defeasance, such additional legal opinions from
Borrower's counsel as Lender reasonably deems necessary to confirm the valid
creation and authority of the Successor Borrower (including a nonconsolidation
opinion), the assignment and assumption of the Loan and Defeasance Collateral
between Borrower and Successor Borrower, and the enforceability of the
assignment documents and of the Loan Documents as the obligation of Successor
Borrower.

                                                              Ply Gem Industries
                                     - 8 -
<PAGE>

            (v) Substitute Notes on Partial Defeasance. With respect to any
partial Defeasance, Borrower shall execute and deliver to Lender all documents
necessary to amend and restate the Note with two substitute notes: one note
having a principal balance equal to the defeased portion of the Loan (the
"DEFEASED NOTE") and one note having a principal balance equal to the undefeased
portion of the Note (the "UNDEFEASED NOTE"). The Undefeased Note may be the
subject of a further Defeasance in accordance with the terms of this Section
2.05(b) (the term "Note", as used in this Section 2.05(b), being deemed to refer
to the Undefeased Note that is the subject of further Defeasance).

            (vi) Defeasance Costs and Expenses. Borrower shall pay reasonable
costs and expenses incurred by Lender in connection with Defeasance, which
payment is required prior to Lender's issuance of the Release and whether or not
Defeasance is completed. Such expenses include, without limitation, the cost
incurred by Lender to obtain Rating Confirmation contemplated by Section
2.05(b)(ii)(D)(8), the reasonable fees and disbursements of Lender's legal
counsel and a processing fee to cover Lender's administrative costs to process
Borrower's Defeasance request. Lender reserves the right to require that
Borrower post a deposit to cover costs which Lender reasonably anticipates will
be incurred.

      (c) Prohibited Prepayment Prior to Open Date. Except as otherwise set
forth in Section 2.05(d), if payment of all or any part of the principal balance
of the Loan is tendered by Borrower, a purchaser at foreclosure, a Guarantor, or
any other Person prior to the Open Date, whether by reason of acceleration of
the Loan or otherwise (a "PROHIBITED PREPAYMENT"), such tender shall be deemed
an attempt to circumvent the prohibition against prepayment set forth in Section
2.05(a) and, at Lender's option, shall be an Event of Default. If a prohibited
prepayment occurs and is accepted voluntarily or otherwise by Lender, then, in
addition to all other rights and remedies available to lender upon an Event of
Default, a Prohibited Prepayment Fee (as defined below) shall be due to
compensate Lender for damages suffered as a result of the Prohibited Prepayment,
such amount shall be due in addition to the outstanding principal balance, all
accrued and unpaid interest and other outstanding amounts due under the Loan
Documents. The "PROHIBITED PREPAYMENT FEE" shall be prepayment premium equal to
the greater of:

            (i)         one percent (1%) of the outstanding principal balance of
                        Note, or

            (ii)        the Yield Maintenance Premium (as defined below).

The "YIELD MAINTENANCE PREMIUM" shall be equal to the excess, if any, of (A) the
present value ("PV") of all scheduled interest and principal payments due on
each Payment Due Date in respect of the Loan for the period from the date of
such accepted prepayment to the Maturity Date, including the principal amount of
the Loan scheduled to be due on the maturity Date, discounted at an interest
rate per annum equal to the Index (defined below), based on a 360-day year of
twelve 30-day months, over (B) the principal amount of the Loan outstanding
immediately before such accepted prepayment [i.e., (PV of all future payments) -
(principal

                                       - 9 -

<PAGE>

balance at time of acceleration)]. The foregoing amount shall be calculated by
Lender and shall be conclusive and binding on Borrower (absent manifest error).

     For purposes hereof, "Index" means the average yield for "treasury
constant maturities" published by the Federal Reserve Board in Federal Reserve
Statistical Release H.15 (519)("FRB Release"), for the second full week
preceding the date of acceleration of the Maturity Date for instruments having
a maturity coterminous with the remaining term of the Loan. If the FRB Release
is no longer published, Lender shall select a comparable publication to
determine the Index. If there is no Index for instruments having a maturity
coterminous with the remaining term of the Loan, then the weighted average
yield to maturity of the Indices with maturities next longer and shorter than
such remaining average life to maturity shall be used, calculated by averaging
(and rounding upward to the nearest whole multiple of 1/100 of 1% per annum, if
the average is not such a multiple) the yields of the relevant Indices
(rounded, if necessary, to the nearest 1/100 of 1% with any figure of 1/200 of
1% or above rounded upward).

            (d) Prepayment as a Result of a Casualty or Condemnation.
Prepayments arising from Lender's application of insurance proceeds upon the
occurrence of a Casualty, the application of a condemnation award upon the
occurrence of a Condemnation, application of the Termination Amount or as set
forth in Section 2.02 (e) may be made prior to the Open Date without being
deemed a Prohibited Prepayment and, whenever made, without payment of the
Prohibited Prepayment Fee.

            (e) Notice Irrevocable. Notwithstanding any provision of this Loan
Agreement to the contrary, Borrower's notice of defeasance in accordance with
subsection 2.05(b) above shall be irrevocable, and the principal balance to be
prepaid shall be absolutely and unconditionally due and payable on the date
specified in such notice.

     4.01.  Creation and Maintenance of Escrows and Reserves.

            (a)  Control of Reserve Accounts. On the Closing date, each of the
Reserve Accounts shall be established by Lender. Each Reserve Account required
under this Loan Agreement shall be a custodial account established by Lender,
and, at Lender's option, funds deposited into a Reserve Account may be
commingled with other money held by Lender. Each Reserve Account shall be under
the sole dominion and control of Lender, and Borrower shall not


                                                              Ply Gem Industries

<PAGE>

have any right to withdraw funds from a Reserve Account. Unless required by the
laws of the state which govern this Loan Agreement or otherwise expressly
provided in this Loan Agreement, Borrower shall not be entitled to any earnings
or interest on funds deposited in any Reserve Account. Upon the occurrence of an
Event of Default, Lender may, in addition to any and all other rights and
remedies available to Lender, apply any sums then present in any or all of the
Reserve Accounts to the payment of the Debt in any order as determined by Lender
in its sole discretion.

         (b) Funds Dedicated to Particular Purpose. Funds held in a Reserve
Account are not to be used to fund Reserve Items contemplated by a different
Reserve Account, and Borrower may not use and Lender shall have no obligation to
apply funds one Reserve Account to pay for Reserve Items contemplated by another
Reserve Account. For example, (i) funds held in the Immediate Repair Escrow
Account shall not be used to pay for Replacements, Tenant Improvements or
Leasing Commissions; (ii) funds held in the replacement Reserve Account shall
not be used to pay for Immediate Repairs, Tenant Improvements or Leasing
Commissions, and (iii) funds held in the TI/LC Reserve Account shall not be used
to pay for Immediate Repairs or Replacements.

         (c) Release of Reserves Upon Payment of Debt. Upon payment in full of
the Loan, Lender shall disburse to Borrower all unapplied funds held by Lender
in the Reserve Accounts pursuant to this Loan Agreement.

         (d) Release of Individual Reserve Account after Full Performance of
Reserve Items. Lender shall disburse to Borrower all unapplied funds remaining
in the Immediate Repair Escrow Account upon receipt of evidence satisfactory to
Lender that (i) Borrower has completed, in the manner required by this Loan
Agreement, all Reserve Items to be funded by such Reserve Account , and (ii) no
Liens exist against the Property with respect to such Reserve Items. Lender
shall not be obligated to make any such disbursement when an Event of Default
exists, and Lender may deduct from such final disbursement all outstanding
amounts then due and unpaid to Lender under the Loan Documents.

         (e) No Obligation of Lender. Nothing in this Loan Agreement shall; (i)
make Lender responsible for making or completing any Reserve Item; (ii) require
Lender to advance, disburse or expend funds in addition to funds then on deposit
in the related Reserve Account to make or complete any Reserve Item; or (iii)
obligate Lender to demand from Borrower additional sums to make or complete any
Reserve Item.

         (f) No Waiver of Default. No disbursements made from a Reserve Account
at the time when a Borrower default or Event of Default has occurred and is then
continuing shall be deemed a waiver or cure by Lender of that default or Event
of Default, nor shall Lender's rights and remedies by prejudiced in any manner
thereby.

         (g) insufficient Amounts in a Reserve Amount. Notwithstanding that
Lender has the right to require Borrower to pay any deficiency in a Reserve
Account if Lender

                                                              Ply Gem Industries

<PAGE>

determines that amounts in a Reserve Account are insufficient, the
insufficiency of funds in a Reserve Account, or Lender's application of funds in
a Reserve Account following an Event of Default other than for funding of the
Reserve Items, shall not relieve Borrower from its obligation to perform in full
each of its: (i) obligations and covenants under this Loan Agreement; (ii)
agreements or covenants with tenants under the Leases; and (iii) agreements with
leasing agents.

      4.02. Tax Escrow.

         (a) Deposits to the Tax Escrow Account. At the option of Lender, (i) at
any time after the occurrence of an Event of Default (as defined therein) under
the Ply Gem Lease, (ii) if the Ply Gem Lease or an Acceptable Replacement Lease
in not in effect, (iii) if at any time Ply Gem is not required by the terms of
the Ply Gem Lease to pay all Taxes due with respect to the Property; (iv) at any
time after there has been a change in ownership of the Property (excluding a
transfer to an Affiliate of Borrower), or (v) at any time after the occurrence
of an Event of Default, Lender may require Borrower to establish the Tax Escrow
Account. If Lender establishes the Tax Escrow Account, then beginning on the
first Payment Due Date following the establishment of the Tax Escrow Account,
and on each Payment Due Date thereafter, Borrower shall deliver to Lender the
Monthly Tax Deposit.

         (b) Disbursement from Tax Escrow Account. Provided amounts in the Tax
Reserve Account are sufficient to pay the Taxes then due and no Event of Default
exists, Lender shall pay the Taxes as they become due on their respective due
dates on behalf of Borrower by applying the funds held in the Tax Escrow Account
to the payments of Taxes then due. In making any payment of Taxes, Lender may do
so according to any bill, statement or estimate obtained from the appropriate
public office with respect to Taxes without inquiry into the accuracy of such
bill, statement or estimate or into the validity of any tax, assessment sale,
forfeiture, tax lien or title or claim thereof.

         (c) Surplus or Deficiency in Tax Escrow Account. If amounts on deposit
in the Tax Escrow Account collected for an annual tax period exceed the Taxes
actually paid during such tax period, Lender shall, in its discretion, return
the excess to Borrower or credit the excess against the payments Borrower is to
make to the Tax Escrow Account for the next tax period. If amounts on deposit in
the Tax Escrow Account collected for an annual tax period are insufficient to
pay the Taxes actually due during such tax period, Lender shall notify Borrower
of the deficiency and, within ten (10) days thereafter, Borrower shall deliver
to Lender such deficiency amount. If , however, Borrower receives notice of any
such deficiency on a date that is within ten (10) days prior to the date that
Taxes are due, Borrower will deposit the deficiency amount within five (5)
business days after its receipt of such deficiency notice.

         (d) Changes in Amount of Taxes Due; Changes in the Monthly Tax Deposit.
Borrower shall notify Lender immediately of any changes to the amounts,
schedules and instructions for payment of any Taxes of which it has or obtains
knowledge and authorizes

                                                              Ply Gem Industries

<PAGE>
Lender or its agent to obtain the bills for Taxes directly from the appropriate
taxing authority. If the amount due for Taxes shall increase and Lender
reasonably determines that amounts on deposit in the Tax Escrow Account will not
be sufficient to pay Taxes due for an annual tax period, Lender shall notify
Borrower of such determination and of the increase needed to the Monthly Tax
Deposit. Commencing with the Payment due Date specified in such notice from
Lender, Borrower shall make deposits at the increased amount of the Monthly Tax
Deposit.

      4.03. Insurance Premium Escrow.

            (a) Deposits to Insurance Premium Escrow Account. At the option of
Lender (i) at any time after the occurrence of an Event of Default (as defined
therein) under the ply Gem Lease, (ii) if the Ply Gem Lease or an Acceptable
Replacement Lease is not in effect, (iii) if at any time Ply Gem is not required
by the terms of the Ply Gem Lease to pay all Insurance Premiums due with respect
to the Property; (iv) at any time after there has been a change in ownership of
the Property ( excluding a transfer to an Affiliate of Borrower), or (v) at any

amount Lender requires to be deposited in connection with the Loan with respect
to environmental matters is less than the amount of the applicable Environmental
Escrow ( as defined in the Ply Gem Lease), then Borrower may cause the
substitution of new Letters of Credit in such reduced amounts.

remains true, complete and correct in all material respects, and no adverse
change in any condition or fact has occurred that would make any of such
information materially inaccurate, incomplete or misleading.

                                    ARTICLE 9
                               BORROWER CONVENANTS

      9.01. Payment of Debt and Performance of Obligations. Borrower shall fully
and punctually pay the Loan and perform the Obligations when and as required by
the Loan Documents. Borrower may not prepay the Loan except in strict accordance
with this Loan Agreement.

      9.02. Payment of Taxes and Other Lienable Charges.

            (a) Payment Obligation. Borrower shall promptly and fully pay by
their due date all Taxes and Other Charges now or hereafter assessed or charged
against the Property as they become due and payable. Borrower shall promptly
cause to be paid and discharged any Lien which may be or become a Lien against
the Property (including, without limitation, mechanic's or materialman's liens).
Except to the extent sums sufficient to pay Taxes or Other Charges have been
deposited with Lender in accordance with this Loan Agreement, Borrower shall
furnish to Lender, upon request, evidence satisfactory to Lender that all Taxes
and Other Charges have been paid and are not delinquent.

            (b) Right to Contest. After prior written notice to Lender,
Borrower, at its own expense, may contest, or permit Ply Gem to contest, by
appropriate legal proceeding, promptly initiated and conducted in good faith
with due diligence, the amount or validity or application in whole or in part of
any of the Taxes or Other Charges, provided that: (i) no Event of Default
exists; (ii) such proceeding suspends the collection of such Taxes or Other
Charges and the Property will not be in danger of being sold for such unpaid
Taxes or Other Charges, or Borrower has paid all of such Taxes or Other Charges
under protest; (iii) such proceeding is permitted under and is conducted in
accordance with the provisions of any other instrument to which Borrower or the
Property is subject and does not constitute a default thereunder; (iv) if
Borrower has not paid the disputed amounts in full under protest, Borrower shall
deposit: with Lender cash (or other security as may be approved, in writing, by
Lender) in an amount Lender deems sufficient to insure the payment of any such
Taxes or Other Charges together with interest and penalties thereon, if any,
provided that after a Securitization, one hundred twenty-five percent (125%) of
the contested amount (plus anticipated penalty and interest) shall be deposited
with Lender; (v) Borrower furnishes to Lender all other items reasonably
requested by Lender; and (vi) upon a final determination thereof, Borrower
promptly pays the amount of any such

                                                             Ply Gem Industries

                                      -32-
<PAGE>

Taxes or Other Charges, together with all costs, interest and penalties which
may be payable in connection therewith. Lender may pay over any security held by
Lender pursuant to this Section to the claimant entitled thereto at any time
when, in Lender's judgment, the entitlement of such claimant is established,
and, to the extent the security posted by Borrower with Lender is insufficient
to pay the full amount due (including, without limitation, any penalties or
interest thereon), Borrower shall be liable for the deficiency. If Lender pays
the deficiency (which Lender shall not be obligated to do), the amount paid by
Lender shall be added to principal, shall bear interest at the Default Rate
until paid in full and payment of such amounts shall be secured by the Security
Instrument and other collateral given to secure the Loan.

      9.03. Insurance.

            (a) Insurance Required During the Loan Term. Borrower, at
Borrower's expense, shall obtain and maintain, or cause to be obtained and
maintained, during the term of the Loan such insurance coverage (including,
without limitation, type, minimum coverage amount, maximum deductible and
acceptable exclusions) for Borrower and the Property as Lender deems reasonably
necessary considering, among other things, the location and occupancy of the
Property and all uses of the Property. Lender reserves the right to periodically
review the insurance coverage Lender has required (types, minimum coverage
amounts and maximum deductibles) and to increase or otherwise change the
required coverage should Lender deem an increase or change to be reasonably
necessary under then existing circumstances. Without limiting Lender's rights
hereunder in any respect, it shall be deemed reasonable for Lender to require no
less coverage than the coverage in place on the Closing Date. Subject to the
foregoing, Lender shall require the following insurance coverage to be effective
during the term of the Loan, coverage amounts and deductibles to be acceptable
to Lender:

                  (i) Property Insurance. Casualty insurance must be maintained
for the Improvements and all Personal Property insuring against any peril now or
hereafter included within the classification "all risks of physical loss" and in
an amount at all times sufficient to prevent Borrower or Lender from becoming a
co-insurer within the terms of the applicable policies, but in any event at all
times equal to the full replacement cost (as reasonably determined and adjusted
from time to time by Lender) of the Improvements and Personal Property (without
taking into account any depreciation and exclusive of excavations, footings and
foundations, landscaping and paving), without any exclusions for windstorms. In
all cases where (A) the outstanding principal balance on the Note exceeds $5
million, or (B) any part of the Improvements constitutes a legal non-conforming
use under the Requirements of Law, such insurance must include "Ordinance of Law
Coverage," with "Time Element," "Loss to the Undamaged Portion of the Building,"
"Demolition Cost" and "Increased Cost of Construction" endorsements, in the
amount of coverage requested by Lender. The policy must name Lender as an
insured mortgagee under a standard mortgagee clause. The maximum deductible
shall be $50,000.00 per occurrence, or, so long as the Ply Gem Lease remains in
effect, such greater amount (up to a maximum of $100,000.00) as shall be
permitted by the Ply Gem Lease,

                                                              Ply Gem Industries

                                      -33-
<PAGE>

provided, however, that Borrower and Guarantor shall be jointly and severally
liable, on a recourse basis, for deductible amounts in excess of $50,000.00.

                  (ii) Insurance against Acts of Terrorism. The insurance
coverage provided under Section 9.03(a) in effect as of the Closing Date and
during the Loan term must also insure against loss or damage resulting from acts
of terrorism or comparable coverage acceptable to Lender in its discretion. The
deductible shall not exceed $100,000.00.

                  (iii) Boiler and Machinery Insurance. Broad form boiler and
machinery insurance (without exclusion for explosion) and systems breakdown
coverage must be maintained, covering all steam boilers, pipes, turbines,
engines or other pressure vessels, electrical machinery, HVAC equipment,
refrigeration equipment and other similar mechanical equipment located in, on or
about the Property in such amount per accident equal to the full replacement
cost thereof (as reasonably determined and adjusted from time to time by Lender)
and also providing coverage against loss of occupancy or use arising from any
breakdown thereof. The policy must name Lender as an insured under a standard
joint loss clause and provide that all proceeds are to be paid to Lender.

                  (iv) Flood Insurance. Flood insurance must be maintained if
any portion of the Improvements is located in an area identified by the Federal
Emergency Management Agency or any successor thereto as a 100-year flood zone or
special hazard area. The required coverage amount shall be the maximum allowable
per building under the then-current guidelines published by the Federal
Emergency Management Agency or any successor thereto. The policy must name
Lender as an insured mortgagee under a standard mortgagee clause. The deductible
may not exceed the greater of five percent (5%) of net cash flow from the
Property, as determined by Lender, or $25,000.00.

                  (v) Business Interruption. Business interruption insurance
must by maintained in an amount sufficient to provide the lost rental income for
the Property for a period of not less than 1 year from the date of Casualty,
with a 6 month extended period of indemnity. For purposes of this coverage,
"rental income" means the sum of (A) the total, then ascertainable Rents payable
under the Leases and (B) the total ascertainable amount of all other payments to
be received by Borrower from third parties which are the legal obligation of the
tenants, reduced to the extent such amounts would not be received because of
operating expenses not incurred during the period that any portion of the
Property cannot be occupied as a result of the Casualty. The policy must name
Lender as a loss payee and provide that all proceeds are to be paid to Lender.

                  (vi) Liability Insurance. Commercial general liability
insurance coverage must be maintained, covering bodily injury or death and
property damage, including all legal liability to the extent insurable and all
court costs, legal fees and expenses, arising out of, or connected with, the
possession, use, leasing, operation, maintenance or condition of the Property in
such amounts generally required by institutional lenders for properties
comparable


                                                              Ply Gem Industries
                                      -34-
<PAGE>

to the Property but in no event for an amount less than $15 million per
occurrence and $15 million in the aggregate. The required coverage must provide
for claims to be made on an occurrence basis. The policy must name Lender as an
additional insured. The insurance coverage required under this subsection (vi)
may be satisfied by a layering of Commercial General Liability, Umbrella and
Excess Liability Policies, but in no event will the Commercial General Liability
policy be written for an amount less than $1,000,000 per occurrence and
$2,000,000 aggregate for bodily injury and property damage liability, and in no
event shall the Umbrella and Excess Liability policy be written for an amount
of less than $5,000,000. Lender may required umbrella coverage which will be
evaluated on a case by case basis.

                  (vii) Workers' Compensation Insurance. Workers' compensation
insurance must be maintained with respect of all employees employed at the
Property, in compliance with the laws of the state in which the Property is
located.

                  (viii) Earthquake Insurance. If the Property is located in a
high earthquake hazard area, earthquake must be maintained in form, amount and
with deductibles satisfactory to Lender.

                  (ix) Other Coverage. Without limiting Lender's rights under
this Section 9.03(a), Lender may also require Borrower to maintain builder's
risk insurance during any period of construction, renovation or alteration of
the Improvements, motor vehicles liability insurance in connection with all
owned or non-owned motor vehicles used in connection with the management or
maintenance of the Property, sinkhole coverage, fidelity bond coverage for
employees handling Rents and other income from the Property, environmental
insurance and other insurance with respect to the Property or on any
replacements or substitutions thereof or additions thereto and in an amount
covering losses to the extent of full replacement cost value against
condemnation and/or other insurable hazards or casualties which at the time are
commonly insured against in the case of property similarly situated, due regard
being given to the height and type of buildings, their construction, location,
use and occupancy. If any construction, renovation or alteration of the
Improvements is done by Ply Gem under the Ply Gem Lease, then Borrower shall
cause Ply Gem to comply with the provisions of the Ply Gem Lease relating
thereto. In furtherance of the forgoing, Lender acknowledges and agrees that it
may only require Borrower to obtain and maintain environmental insurance or
cause the same to be obtained and maintained under the following circumstances:
(i) to the extent that an environmental condition arises that is subject to
Environmental Law and affects the Property and such condition was not known to
Lender on or before the date hereof or disclosed in the Environmental Report and
the cost of Remediation thereof, as reasonably determined by Lender will be more
than $500,000; or (ii) to the extent the environmental condition was known to
Lender on or before the date hereof or disclosed in the Environmental Report and
there has been a material change in said condition such that (a) the cost to
remediate has increased by more than $500,000.00 and any reserve or additional
security provided to remediate such condition is not sufficient to cover such
increased cost, or

                                                              Ply Gem Industries
                                      -35-
<PAGE>
(b) the condition shall materially impair the use and operation of the business
of the tenant at the property;

            (x) Tenant's Insurance. Notwithstanding anything in the Section 9.03
to the contrary, and provided that (i) the Ply Gem Lease or an Acceptable
Replacement Lease, as applicable, remains in effect with Ply Gem, or an
Acceptable Replacement Tenant, as applicable, as the tenant thereunder, (ii) Ply
Gem or an Acceptable Replacement Tenant is not in default beyond the expiration
of any applicable notice and cure period under the Ply Gem Lease or an
Acceptable Replacement Lease, as applicable, and (iii) Ply Gem or an Acceptable
Replacement Tenant carries all insurance required under the Ply Gem Lease or an
Acceptable Replacement Lease, as applicable, then the requirements of Sections
9.03(a) shall be deemed satisfied, except that with respect to Borrower's
continuing obligation to maintain terrorism insurance, Borrower shall cause Ply
Gem or an Acceptable Replacement Tenant at all times to maintain terrorism
insurance in such amounts as are customary for properties of sizes, types and
uses as the Property. Notwithstanding the foregoing, so long as Ply Gem
maintains a self-insured retention limit in excess of $50,000.00, Borrower shall
maintain excess liability insurance with a self-insured retention not in excess
of $50,000.00 and otherwise meeting the requirements of this Section 9.03
hereof.

      (b) Qualified Insurers; Lender's Consent. All insurance must be issued
under valid and enforceable policies of insurance acceptable to Lender and
issued by one or more domestic primary insurers authorized to issue insurance in
the state in which the Property is located. Each insurer must have a minimum
investment grade rating of "A" or better from S & P and an A.M. Best rating of
A:IX or better, or from an equivalent comparable credit rating agency acceptable
to Lender. With respect to insurance required under Section 9.03(a)(i) above,
Lender agrees to accept policies written by Factory Mutual Insurance Company
("F.M. GLOBAL") during any period that F.M. Global does not have an A or better
S & P claims paying ability rating, so long as F.M. Global has Best's rating of
A:IX or above. Lender's approval of insurance coverage at any time is not a
representation or warranty concerning the sufficiency of any coverage or the
solvency of any insurer, and Lender shall not be responsible for, nor incur any
liability for, the insolvency of the insurer or other failure of the insurer to
perform.

      (c) Policy Requirements. All policies must be for a term of not less than
a year and name Lender as a beneficiary of such coverage as provided in this
Section 9.03 or otherwise identified by Lender. Each policy must also contain:
(i) an endorsement or provision that permits recovery by Lender notwithstanding
the negligent or willful acts or omissions of Borrower, (ii) a waiver of
subrogation endorsement as to Lender to the extent available at commercially
reasonable rates; (iii) a provision that prohibits cancellation or termination
before the expiration date, denial of coverage upon renewal, or material
modification without at least thirty (30) days prior written notice to Lender in
each instance; and (iv) effective waivers by the insurer of all claims for
Insurance Premiums against Lender. If the required insurance coverage is to be
provided under a blanket policy covering the Property and other properties and
assets not part of the Property, such blanket policy must specify the portion of
the total coverage that is

                                                              Ply Gem Industries

                                      -36-
<PAGE>
allocated to the Property and any sublimit in such blanket policy which is
applicable to the Property and shall otherwise comply in all respects with the
requirements of this Section 9.03.

            (d) Evidence of Insurance. Borrower must deliver to Lender on or
before the Closing Date either (i) the original of each insurance policy
required hereunder, (ii) a copy of each original policy certified by the
insurance agent to be a true, correct and complete copy of the original; (iii)
the insurance binder (Acord Form 25S provided by the insurance carrier) (as well
as proof of payment of the first years premium); (iv) a certificate of insurance
(Acord Form 28 provided by the insurance agent of, where form Acord Form 28 is
not available, a certificate of insurance that confirms the same rights as are
confirmed by form Acord Form 28), (v) an original letter from the insurance
carrier on the primary layer, signed by an officer of such carrier, attaching
the form of insurance policy pursuant to which coverage will be provided (and,
if applicable, an original letter from each insurance carrier on the excess
layers, signed by an officer of each such carrier, agreeing that it is bound to
the form of insurance policy delivered by the primary carrier (i.e., agreeing to
"follow form" to the primary carrier)); and (A) each such letter must set forth
the date by which the policy will be delivered to the Lender, which must not be
more than sixty (60) days following closing and (B) include as attachments all
mortgagee/loss payee/additional insured endorsements. Evidence of the required
coverage for the first year of the Loan (as well as proof of payment of the
first year's premium) must be delivered to Lender on or before the Closing Date
and thereafter not less than ten (10) days prior to the expiration date of each
policy.

            (e) Lender's Right to Obtain Insurance for Borrower. If Borrower
fails to deliver to Lender the evidence of the insurance coverage required by
this Loan Agreement and does not cure such deficiency within ten (10) days after
Lender's notice of nondelivery, an Event of Default shall be deemed to have
occurred (without further cure period or notice) and Lender may procure such
insurance at Borrower's expense, without prejudice to Lender's rights upon an
Event of Default. All amounts advanced by Lender to procure the required
insurance shall be added to principal, secured by the Security Instrument and
bear interest at the Default Rate. Lender shall not be responsible for, nor
incur any liability for the insolvency of the insurer or other failure of the
insurer to perform, even though Lender has caused the insurance to be placed
with the insurer after Borrower's failure to furnish such insurance.

            (f) Additional Insurance. Borrower shall not obtain insurance for
the Property in addition to that required by Lender without Lender's prior
written consent, which consent will not be unreasonably withheld provided that
(i) Lender is named insured on such insurance, (ii) Lender receives evidence of
such insurance as required by subsection (d) above, and (iii) such insurance
complies with all of the applicable requirements set forth in this Loan
Agreement.

      9.04. Obligations upon Condemnation or Casualty. If the Property, or any
portion thereof, shall be damaged or destroyed by a Casualty or become subject
to any Condemnation, the following shall apply:

                                                              Ply Gem Industries

                                     - 37 -
<PAGE>

      (a) Generally. Upon receiving notice thereof, Borrower shall promptly
notify Lender, in writing, of any actual or threatened Condemnation or of any
Casualty that damages or renders unusable the Property or any part thereof and,
except as otherwise provided below, shall promptly and diligently pursue, or
cause to be pursued, Borrower's claim for a Condemnation award or insurance
proceeds, as applicable. Borrower shall not make any agreement in lieu of
Condemnation or accept any Condemnation award without Lender's prior written
consent, which shall not be unreasonably withheld or delayed. Borrower shall not
accept any settlement of insurance proceeds with respect to a Casualty without
Lender's prior written consent, which shall not be unreasonably withheld or
delayed. If requested by Lender, Borrower agrees to provide copies to Lender of
all notices or filings made or received by Borrower in connection with the
Casualty or Condemnation or with respect to collection of the insurance proceeds
or Condemnation award, as applicable. Notwithstanding that a Casualty or
Condemnation has occurred, or that rights to a Condemnation award or insurance
proceeds are pending, Borrower shall continue to pay the Loan at the time and in
the manner provided in this Loan Agreement.

      (b) Lender Right to Pursue Claim. Borrower hereby grants Lender the
authority, at Lender's option, subject to the rights of Ply Gem under the Ply
Gem Lease, either : (i) to settle and adjust any claim arising with respect to
the Casualty or Condemnation without Borrower's consent, or (ii) to allow
Borrower to settle and adjust such claim; provided that, in either case, the
insurance proceeds or Condemnation award in excess of $250,000, as applicable,
is paid directly to Lender. Borrower hereby appoints Lender its attorney -in-
fact with full power of substitution (and which shall be deemed to coupled with
an interest and irrevocable until the Loan is paid and the Security Instrument
is discharged of record, with Borrower hereby ratifying all that its said
attorney shall do by virtue thereof) to endorse any agreements, instruments or
drafts received in connection with a Casualty or Condemnation. If any portion
of the insurance proceeds or Condemnation award in excess of $250,000, as
applicable, should be paid directly to Borrower, Borrower shall be deemed to
hold such amounts in trust for Lender and shall promptly remit such amounts to
Lender. If the Property is sold, through foreclosure or otherwise, prior to the
receipt of the Condemnation award, Lender shall have the right, whether or not a
deficiency judgement on the Note shall have been sought, recovered or denied,
to receive the proceeds of such sale in an amount sufficient to pay the Loan in
full subject, however to the rights of Ply Gem or Acceptable Replacement Tenant
under the Ply Gem Lease or Acceptable Replacement Lease. All expenses incurred
by lender in the settlement and collection of amounts paid with respect to a
Casualty or Condemnation (including, without limitation, reasonable legal fees
and expenses) shall be deducted and reimbursed to Lender from the insurance
proceeds or Condemnation award, as applicable, prior to any other application
thereof. The insurance proceeds or Condemnation award paid or payable on account
of a Casualty or Condemnation, as applicable (including all business
interruption insurance proceeds paid as a result of such Casualty or
Condemnation), less expenses to be reimbursed to Lender hereunder, is referred
to herein as the "RESTORATION PROCEEDS."

      (c) Application of Restoration Proceeds; Restoration Obligations. Except
as specifically hereafter provided in subsection (d) below, Lender may, in its
sole discretion, either

                                                              Ply Gem Industries
                                      -38-
<PAGE>
            (i)   apply the Restoration Proceeds to payment of the Loan, whether
or not then due and payable, or (ii) hold and release the Restoration Proceeds
to Borrower (A) for the costs of Restoration undertaken by Borrower in
accordance with this Loan Agreement and (B) to cover any shortfall in Operating
Income as a result of such Casualty or Condemnation that is necessary to pay in
full the debt service payments due from Borrower on each Payment Due Date and
other Operating Expenses falling due during the period until Restoration is
completed; provided, however, that Lender shall have no obligation to release
Restoration Proceeds to fund amounts contemplated by clause (B) unless (1)
Lender is satisfied that Restoration Proceeds are sufficient to pay in full the
estimated cost to complete Restoration and (2) all Operating Expenses to be
funded with Restoration Proceeds are approved by Lender. If Lender applies
Restoration Proceeds to payment of the Loan and the Loan is still outstanding,
interest will continue to accrue and be due on the unpaid principal at the
Applicable Interest Rate. If Lender makes the Restoration Proceeds available to
Borrower for Restoration, Borrower shall diligently pursue, or cause to be
diligently pursued, Restoration so as to restore the Property to at least equal
value and substantially the same character as existed immediately prior to such
Casualty or Condemnation. All plans and specifications for the Restoration and
all contractors, subcontractors and materialmen to be engaged in the
Restoration, as well as the contracts under which they have been engaged, shall
be subject to Lender's prior review and approval. Lender may engage, at
Borrower's expense, an independent engineer or inspector to assist Lender in
its review of the approvals requested of Lender in connection with the
Restoration and to periodically inspect the Restoration in progress and upon
substantial completion.

      (d) Condition to Release of Restoration Proceeds for Restoration. Lender
agrees to make the Restoration Proceeds available to Borrower for Restoration
as long as.

            (i)   The Restoration Proceeds recovered are less than the
outstanding principal balance of the Loan.

            (ii)  No Event of Default exists and no Event of Default then
exists under the Ply Gem Lease or Acceptable Replacement Lease, as applicable.

            (iii) Borrower demonstrates to Lender's satisfaction that the
Restoration Proceeds are sufficient to pay in full the estimated cost to
complete Restoration and, if the Ply Gem Lease or an Acceptable Replacement
Lease is not in effect, any shortfalls in Operating Income as a result of such
Casualty or Condemnation that are anticipated until Restoration is substantially
completed, or, if the Restoration Proceeds are determined by Lender to be
insufficient to pay such costs in full, Borrower deposits with Lender, in cash
or by a cash equivalent acceptable to Lender, the additional amount estimated by
Lender to be necessary to pay the full cost of Restoration ("RESTORATION
DEFICIENCY DEPOSIT")

            (iv)  The Casualty or Condemnation has not occurred in the six (6)
months prior to the Maturity Date.

                                                              Ply Gem Industries

                                      -39-
<PAGE>

            (v) Restoration can be completed not later than the earlier of (A)
twelve (12) months from the date the Casualty or Condemnation occurred, (B) the
earliest date by which completion is required under the Ply Gem Lease, or an
Acceptable Replacement Lease, (C) the earliest date by which completion is
required under the Requirements of Law to preserve the right to rebuild the
Improvements as they existed prior to the Casualty or Condemnation, (D) the
expiration of Borrower's business interruption insurance, or (E) six (6) months
prior to the Maturity Date.

            (vi) If a Condemnation has occurred, less than 10% of the Land is
taken and the land taken is along the perimeter or periphery of the Land, and no
portion of the Improvements are taken.

            (vii) If a Casualty has occurred, less than 25% of the total floor
area of the Improvements is damaged or rendered unusable by the Casualty and
Borrower demonstrates to Lender's satisfaction that a reasonable means of access
exists to the Property and within the Improvements unaffected by Casualty.

            (viii) Borrower demonstrates to Lender's satisfaction that the Ply
Gem Lease or an Acceptable Replacement Lease, as applicable, will continue in
full force and effect without rent abatement following Restoration and that,
upon completion of Restoration, the net cash flow of the Property will be
restored to a level sufficient to cover all Operating Expenses of the Property,
including without limitation, supporting a Debt Service Coverage Ratio at least
equal to, or greater than 1.20 to 1.0.

            (ix) The Property and its use after completion of Restoration will
be in compliance with and permitted under, all Requirements of Law.

      (e) Disbursement Procedure; Holdback. If the Restoration Proceeds will be
made available by Lender to Borrower for Restoration and the estimated cost of
Restoration approved by Lender (together with all other amounts then held by
Borrower pursuant to this subsection (c)) is less than $250,000, Lender shall
disburse the entire amount of the Restoration Proceeds to Borrower or to Ply Gem
at the direction of Borrower, and Borrower hereby covenants and agrees to use,
or to cause Ply Gem to use, the Restoration Proceeds solely for Restoration
performed in accordance with this Loan Agreement. If, however, the estimated
cost of Restoration approved by Lender (together with all other amounts then
held by Borrower pursuant to this subsection (e)) is more than $250,000, Lender
may retain the Restoration Proceeds in a non-interest bearing escrow account and
make periodic disbursement to Borrower (or to Ply Gem at the direction of
Borrower) as follows:

            (i) Disbursements for Restoration

                  (A) Lender will disburse Restoration Proceeds for the costs of
Restoration to, or as directed by, Borrower from time to time during the course
of the Restoration, upon receipt of evidence reasonably satisfactory to Lender
that (1) all materials
                                                              Ply Gem Industries

installed and work and labor performed in connection with the Restoration have
been paid in full (except to the extent that they are to be paid out of the
requested disbursement), and (2) there exist no notices of pendency,
stop orders, mechanic's or materialman' s liens or notices of intention to file
same, or any other Liens of any nature whatsoever on the Property arising out of
the Restoration which have not either been fully bonded and discharged of record
or, in the alternative, fully insured to Lender's reasonable satisfaction by the
title company insuring the Lien of the Security Instrument.

                  (B) Lender may limit disbursements to not more than one (1)
per month.

                  (C ) Lender may hold-back from each requested (disbursement an
amount equal to the greater of (1)ten percent (10%) of the requested
disbursement) or (2) the amount which Borrower is permitted to withhold under
its contract with the contractor or supplier to be paid with the proceeds of
such disbursement (either a "RESTORATION HOLDBACK"). Amounts held as the
Restoration Holdback shall be disbursed once: (1) Lender receives Substantially
evidence that Restoration has been substantially Completed (as defined below) in
accordance with all Requirements of Law; (2) Lender receives satisfactory
evidence that all Restoration costs have been paid in full or will be fully paid
from the remaining Restoration Proceeds and the Restoration Holdback; and (3)
Lender receives, at Lender's option, a search of title to the Property,
effective as of the date on which the restoration Holdback is to be disbursed,
showing no liens other than the permitted Encumbrances or an endorsement to its
Title Insurance Policy which updates the effective date of such policy to the
date on which the Restoration Holdback is to be disbursed and which shows no
Line since the date of recordation of the Security Instrument (other than the
permitted Encumbrances). As used herein, the term "SUBSTANTIALLY COMPLETED"
shall mean the completion of construction, except for miner details of
construction, decoration and mechanical adjustment, the non-completion of which
will not materially interfere with the use and occupancy of the Property for
normal business purposes.

                  (D) Notwithstanding subsection (C) above, Lender may release
from the Restoration Holdback payments to a contractor or supplier if: (1)
Lender receives satisfactory evidence that such contractor has satisfactory
completed its contract with Borrower; (2) such contractor or supplier delivers
to Lender an acceptable written waiver of its mechanic's lien, in recordable
form; and (3) Borrower provides written consent from the surety company, if any,
which has issued a payment or performance bond with respect to such contractor
or supplier.

            (ii) Disbursements for Shortfalls in Operating Income. Provided that
Lender determines that the Restoration Proceeds are sufficient to pay in full
the estimated cost to complete Restoration Proceeds not reserved for Restoration
to pay the shortfall in Operating Income necessary to pay (A) first, the debt
service payments due from Borrower on each Payment Due Date falling due from the
date of the Casualty or Condemnation through the date on which Restoration is
substantially completed and (B)
                                                              Ply Gem Industries

Lease is them in effect, any Operating Expenses approved by Lender. Lender may
require satisfactory evidence that Operating Expenses to be paid have been
incurred any may issue payments directly to the Person entitled to the payment
claimed as an Operating Expense.

            (iii) Restoration Proceeds Deemed Insufficient. If, in Lender's
reasonable judgment, at any time during Restoration, the undisbursed portion of
the Restoration Proceeds shall not be sufficient to pay the costs remaining for
Restoration to be completed or to pay any shortfall in Operating Income needed
to pay in full Borrower's debt service payments on the Loan and Operating
Expenses anticipated to be incurred during the period of Restoration, Borrower
shall deposit the deficiency with Lender, in cash or by a cash equivalent
acceptable to Lender (also called a "RESTORATION DEFICIENCY DEPOSIT"), within
ten (10) days after Lender's notice of such deficiency, and no further
disbursement of the Restoration Proceeds will be made until such funds are
deposited. Amounts held by Lender as the Restoration Deficiency Deposit shall be
held by Lender in an interest bearing account and shall be disbursed accordance
with this Section 9.04.

            (iv) Consequence of Event of Default. If a default under the Ply Gem
Lease has occurred and is continuing or the Ply Gem Lease has been terminated
and no Acceptable Replacement Lease is in full force and effect or and Event of

obligated to disburse Restoration Proceeds or amounts from the Restoration
Holdback, and upon the occurrence of and Event of Default, any undisbursed
portion of the Restoration Proceeds (including the Restoration Deficiency
Deposit and the Restoration Holdback) may, at Lender's option, be applied
against the Loan, whether or not then due or accelerated, in such order and
manner as Lender determines.

            (v) Surplus Restoration Proceeds After Restoration Completion. Any
Restoration Proceeds remaining after full payment of Restoration costs and
unpaid expenses due to Lender for which Lender is permitted reimbursement under
this Section 9.04 shall be released to Borrower provided no Event of Default
exists, and Borrower delivers evidence satisfactory to Lender that (i)
Restoration has been fully completed in accordance with all Requirements of Law
and (ii) the Property is free and clear of all Liens which may be asserted with
respect to the Restoration.

      (f) If as a result of a Casualty or Condemnation, the tenant under the Ply
Gem Lease makes a rejectable offer under Paragraph 18 thereof, to terminate the
Ply Gem Lease as to any Related Premises ( as defined in the Ply Gem Lease )
which is accepted by Borrower, then upon satisfaction of the Casualty Release
Criteria (hereinafter defined), Lender shall deliver to Borrower a release or
partial release of the Security Instrument for the Related Premises with respect
to which the Ply Gem Lease is terminated (hereinafter the "AFFECTED PREMISES").
As used herein, the term "CASUALTY RELEASE CRITERIA" shall mean and refer to the
following: (i) Borrower shall have delivered to Lender a sum of money in
immediately available funds (the
                                                              Ply Gem Industries


                                      -42-

outstanding principal balance of the Note allocated to the Affected Premises;
and (ii) the Borrower shall not then be in default hereunder or the other Loan
Documents beyond any applicable notice and/or cure period. Upon Lender's receipt
of the Casualty Release Amount, Lender shall apply such sum at par, without
prepayment penalty or premium or defeasance payment, to reduction of the
outstanding principal balance of the Note, and thereafter, at Lender's option in
its sole discretion, monthly payments due under the Note shall be recalculated
based upon the remaining outstanding Principal balance of the Note, the
remainder of the original amortization schedule of the Note and the remaining
term of the Loan. Borrower shall not reject any offer to terminate the Ply Gem
Lease with respect to an Affected Premises, without first obtaining the written
consent of Lender.

the tenant thereunder, and (ii) Ply Gem is not in default beyond the expiration
of any applicable notice and cure period under the Ply Gem Lease, then (A) the
requirements of Section 9.04(d)(ii) hereof shall be deemed satisfied, unless a
monetary Event of Default or a material non-monetary Event of Default then
exists under the Note, this Loan Agreement or any of the other Loan Documents,
and (B) the requirements of Sections 9.04(d)(v), (vi), (vii) and hereof shall be
deemed satisfied, unless Lender has reasonably determined that the Restoration
cannot be reasonably completed on or before the date that is six (6) months
prior to the Maturity Date.

      9.05. Inspections and Right of Entry. Subject to the terms of the Ply Gem
Lease, Lender and its agents may enter the Property upon prior notice to
Borrower (notice to be given unless an Event of Default or an emergency exists,
as determined by Lender in good faith) to inspect the Property and Borrower's
books and records relating to the Property. In making such entry and inspection,
Lender agrees to use reasonable efforts to minimize disturbance to Borrower and
tenants of the Property. Lender and its agents shall have access, at all
reasonable times, to the Property, including, without limitation, all contracts,
plans and specifications, permits, licenses and approvals required or obtained
in connection with the property.

      9.06. Leases and Rents.

            (a) Right to Enter into New Leases. Lender's prior written consent
shall be required for all Leases at the Property, which consent shall not be
unreasonably withheld, provided that Lender's consent shall not be required for
assignments and subleases which do not require the consent of the Borrower as
landlord under the Ply Gem Lease. Upon request, Borrower shall furnish Lender
with executed copies of all Leases. Lender acknowledges receipt and approval of
the Ply Gem Lease, which Ply Gem Lease shall constitute one of the Leases.

            (b) Leasing Decisions. Borrower shall not: (i) amend or supplement
any Lease or waive any term thereof (including, without limitation, shortening
the lease term, reducing rents, granting rent abatements, or accepting a
surrender of all or any portion of the

                                                              Ply Gem Industries

                                     - 43 -

leased space) without Lender's prior written consent, which shall not be
unreasonably withheld or delayed; (ii) cancel or terminate any Lease (or in the
case of the Ply Gem Lease, reject any termination offer); (iii) except to the
extent that such consent is not required under the Ply Gem Lease, consent to a
tenant's assignment of its Lease or subleasing of space without Lender's prior
written consent, which shall not be unreasonably withheld or delayed; or (iv)
amend, supplement, waive or terminate any Lease Guaranty without Lender's prior
written consent, which stall not be unreasonably withheld or delayed; provided
that none of the foregoing actions (taking into account the planned alternative
use of the affected space in the case of termination, rent reduction, surrender
of space or shortening of term) will have a Material Adverse Effect on the value
of the Property taken as a whole and such Lease, as amended, supplemented or
waived is otherwise in compliance with the requirements of Section 9.06 (a)
hereof; provided, however, that in all events Borrower shall have the right to
waive any default under Paragraph 22(a)(iv) and (v) of the Ply Gem Lease without
Lender's consent. Termination of a Lease (other than a Major Lease) with a
tenant who is in default beyond applicable notice and grace/cure periods shall
not be considered action which has a Material Adverse Effect on the value of the
Property taken as a whole. Any action with respect to any Lease that does not
satisfy the requirements set forth in this Section requires Lender's prior
written approval at Borrower's expense (including reasonable legal fees).
Borrower shall promptly deliver to Lender a copy of all instruments documenting
the action taken, together with written certification from a Responsible Officer
that (x) the copies delivered are true, complete and correct copies of the
materials represented thereby and (y) Borrower has satisfied all conditions of
this Section. Lender's acceptance of Borrower's certification or a copy of such
Lease materials shall not be deemed a waiver of the requirements of this Section
if the action taken is not in compliance herewith. Lender agrees that to the
extent any action by Ply Gem requires Lender's consent, such consent shall not
be unreasonably withheld or delayed. If Borrower submits to Lender a written
request for approval with respect to a proposed Lease (or a proposed extension,
modification or expansion of an existing Lease) and Lender fails to approve or
disapprove any such action within 15 Business Days after Lender receives from
Borrower such request together with a copy of the final version of such proposed
Lease(or proposed extension, modification or expansion of an existing Lease),
such action shall be deemed approved, provided that Lender will only be deemed
to have given such approval if, and only if, such request includes all to the
supporting documentation reasonably necessary for Lender to make a decision
regarding such request, as determined by Lender, and includes the following in
all capital, bolded, block letters on the first page thereof:

            "THE FOLLOWING REQUEST REQUIRES A RESPONSE WITHIN 15 BUSINESS DAYS
            OF RECEIPT. FAILURE TO DO SO WILL BE DEEMED AND APPROVAL OF THE
            REQUEST."

            (c) Observance of Lessor Obligations. Borrower (i) shall observe and
perform all obligations imposed upon the lessor under the Lease and shall not do
or permit to be done anything to impair the value of any of the Leases as
security for the Loan; (ii) upon Lender's request, shall promptly send copies to
Lender of all notices of default which Borrower

                                                              Ply Gem Industries

                                     - 44 -
<PAGE>

shall send or receive (or may have sent or received) under any non-residential
Lease; (iii) shall diligently enforce in a commercially reasonable manner all of
the material terms, covenants and conditions contained in the Leases to be
observed or performed by the tenant, including but not limited to those items
listed on Exhibit I to the Ply Gem Lease; provided, however, that Borrower may,
in its sole discretion, waive any breach by Ply Gem or any Acceptable
Replacement Tenant of any reporting requirement in the Ply Gem Lease or
Acceptable Replacement Lease, (iv) shall not collect any Rents more than one (1)
month in advance of the date when due under the Lease (and for this purpose a
security deposit shall not be deemed rent collected in advance and provided
further that rent under the Ply Gem Lease or Acceptable Replacement Lease may be
collected no more than three (3) months in advance); and (v) shall not execute
any assignment or pledge of the lessor's interest in any of the Leases or the
Rents (other than in connection with the Loan).

            (d) Landlord Waivers. Lender acknowledges that Borrower may enter
into certain Landlord Waivers with respect to Ply Gem's equipment, personal
property and inventory located in, on and around the Property, and that Borrower
shall be entitled to enter into Landlord Waivers in the future without Lender's
consent so long as they are entered into in a form approved in advance by Lender
and in the normal course of business and contain customary provisions and
otherwise reasonably acceptable to Lender requiring the person, firm or entity
that finances and/or leases Ply Gem's FF&E to promptly remove Ply Gem's FF&E
within a reasonable period of time after a default occurs under the Ply Gem
Lease. In addition, Borrower shall be entitled to enter into a consent (and
Lender shall also execute such consent if requested by Borrower) to any
encumbrance by Ply Gem of its leasehold interest so long as such consent
contains reasonable and customary landlord protections. Lender has no obligation
to enter into a nondisturbance or recognition agreement with any such leasehold
mortgagee unless and until such time as such leasehold mortgagee shall succeed
to the interest of Ply Gem under the Ply Gem Lease, in which case Mortgagee
shall enter into a subordination, nondisturbance and attornment agreement
substantially the same in form and substance to the subordination,
nondisturbance and attornment agreement entered into among Borrower, Ply Gem and
Lender in connection with the closing of the Loan, so long as any and all
monetary defaults under the Ply Gem Lease have been cured by such leasehold
mortgagee.

            9.07. Use of Property. Subject to the rights of Ply Gem under the
Ply Gem Lease, Borrower shall not allow changes in the use of the Property
without Lender's prior written consent, which shall not be unreasonably
withheld, delayed or conditioned as to uses permitted by law and under zoning.
Borrower shall not initiate, join in, or consent to any change in any private
restrictive covenant or zoning or land use ordinance limiting or defining the
uses which may be made of the Property. If use of all or any portion of the
Property is or shall become a nonconforming use, Borrower will not cause or
permit the nonconforming use to be discontinued or the nonconforming portion of
the Property to be abandoned without Lender's prior written consent.

                                                              Ply Gem Industries

any Acceptable Replacement Tenant to maintain the Property in a good and safe
condition and repair. No portion of the Property shall be removed, demolished or
materially altered (except for normal repair or replacement or, with respect to
the Personal Property belonging to Ply Gem, as otherwise permitted by the terms
of the Ply Gem Lease) without Lender's prior written consent, which consent
shall not be unreasonably withheld, delayed or conditioned. Unless the Ply Gem
Lease is in effect and Ply Gem makes a termination offer pursuant to the terms
of Paragraph 18 of the Ply Gem Lease, which termination offer shall be
sufficient for and shall be used to pay the applicable portion of the Loan in
strict accordance with Section 9.04(f) of this Loan Agreement or to substitute a

Property or do or permit to be done thereon anything that may in any way impair
the value of the Property in any material respect (in Lender's sole good faith
judgment) or invalidate the insurance coverage required hereunder to be
maintained by Borrower. Borrower will not, without Lender's prior written
consent, permit any drilling exploration for or extraction, removal, or
production of any minerals from the surface or the subsurface of the Property,
regardless of the depth thereof or the method of mining or extraction thereof.

      9.10. Compliance with Laws.

            (a) Obligation to Perform. Borrower shall promptly and fully comply
with, or cause to be complied with, in all material respects, all Requirements

other documents relating to any litigation or governmental investigation
relating to Borrower or the Property.

            (b) Right to Contest. After prior written notice to Lender,
Borrower, at its own expense, may contest or permit Ply Gem or an Acceptable
Replacement Tenant to contest by appropriate legal proceedings, promptly
initiated and conducted in good faith and with due diligence, the Requirements
of Law affecting the Property or alleged violation thereof, provided that: (i)
no Event of Default exists; (ii) such proceedings shall be permitted under and
be conducted in accordance with the Requirements of Law; (iii) the Property will
not be in danger of being sold, forfeited, terminated, cancelled or lost; (iv)
non-compliance with such Requirement of Law shall not impose any civil, criminal

acceptable to Lender) in such amount as Lender deems sufficient to cover loss
or damage that may result from Borrower's failure to prevail in such contest,
provided that after a Securitization, one hundred twenty-five percent (125%) of
the amount estimated by Lender is deposited; (vi) Borrower furnishes to Lender
all other items reasonably requested by Lender, and (vii) upon a final

Default, existing, not more than annually and upon prior notice to Borrower
(notice to be given unless an Event of Default exists), to have an independent
audit conducted of any of Borrower's financial information. Lender shall pay the
cost of such audit unless Lender performed the audit following the occurrence of
an Event of Default to if the results of Lender's audit disclose an error by
more than ten percent (10%), in which case (and in addition to Lender's other
remedies) Borrower shall pay the cost incurred by Lender with respect to such
audit upon Lender's demand. Upon Borrower's failure to pay such amounts, and in

Borrower shall pay Lender, without demand, the applicable Data Delivery failure
fee on the first Business Day following each occurrence of a Data Delivery
Failure . The collection of the Data Delivery Failure Fee shall be in addition

bear interest at the Default Rate.

cause to be observed and performed) in a timely manner each and every obligation
to be observed or performed by Borrower pursuant to the terms of any agreement
or recorded instrument affecting or pertaining to the Property or, if Borrower

consent (which shall not be unreasonably withheld or delayed), except as may be
(i) permitted pursuant to the respective terms thereof or (ii) absent the
existence of an Event of Default, done in the ordinary course of business. If
the absence of an Operating Agreement that has terminated will have a Material
Adverse Effect on the value of the Property, Borrower agrees to enter into a new
Operating Agreement in replacement of the terminated Operating Agreement,
containing terms and conditions no less favorable to Borrower than the
terminated Operating Agreement. Borrower shall notify Lender if Borrower does
not replace the terminated Operating Agreement.

the Property Manager) or modify or waive any material terms of the Property
Management Contract without Lender's prior written consent, which shall not be
unreasonably withheld or delayed, and, if requested by Lender, a Rating
Confirmation. Upon replacement of the Property Manager, Borrower shall, and
shall cause the new manager of the Property to, execute an Assignment of
Property Management Contract in form and substance similar to the Assignment of
Property Management Contract executed by the Property Manager. Borrower shall

Assignment of Property Management Contract. The property management fee and all
other fees payable under the Property Management Contract shall not exceed three
percent [3%] of gross revenues. Notwithstanding the foregoing, Borrower shall be
permitted to manage the property so long as no management fees are paid to
Borrower, Borrower is managing the Property in the manner that the property is
maintained as of the date hereof, and the Debt Service Coverage Ratio is not
less than 1.20 to 1.0. If Borrower ceases self-management and engages a
third-party manager for the Property, Borrower shall comply with all of the
provisions hereof regarding replacement of the Property Manager, including
without limitation, the execution of an Assignment of Property Management
Contract on Lender's then standard form and Lender acknowledges that Ply Gem
currently self-manages the Property.

            (b) Termination of Property Manager. Irrespective of whether an
Event of Default has occurred, Borrower agrees, that if (a) Lender, in its
reasonable discretion, determines that the Property is not being properly
managed in accordance with management practices customarily employed for
properties similar to the Property, or (b) Property Manager becomes insolvent,
then Lender may deliver written notice to Borrower and Property Manager, which
notice shall specify in reasonable detail the grounds for Lender's
determination. If Lender reasonably determines that the conditions specified in
Lender's notice are not remedied to Lender's reasonable satisfaction by Borrower
or Property Manager within thirty (30) days from receipt of such notice, or if
Borrower or Property Manager have failed to diligently undertake correcting such
conditions within such thirty (30) day period, Lender may direct Borrower to
terminate the Property Management Contract and/or cease self-management and
replace Property Manager with a management company acceptable to Lender.

      9.15. ERISA. Borrower shall not engage in any transaction which would
cause any obligation or action taken or to be taken hereunder by Borrower (or
the exercise by Lender of any of its rights under any of the Loan Documents) to
be a non-exempt (under a statutory or administrative class exemption) prohibited
transaction under ERISA. Borrower agrees to deliver to Lender such
certifications or other evidence throughout the term of the Loan as requested by
Lender in its sole discretion to confirm compliance with Borrower's obligations
under this Section 9.15 or to confirm that Borrower's representations and
warranties regarding ERISA remain true.

      9.16. Compliance with Anti-Terrorism, Embargo, Sanctions and Anti-Money
Laundering Laws. Borrower shall comply with all Requirements of Law relating to
money laundering, anti-terrorism, trade embargos and economic sanctions, now or
hereafter in effect. Without limiting the foregoing, Borrower shall not take any
action, or permit any action to be taken, that would cause Borrower's
representations and warranties in Section 8.28 of this Loan Agreement to become
untrue or inaccurate at any time during the term of the Loan. Borrower shall
notify Lender promptly of Borrower's actual knowledge that the representations
and warranties in Section 8.28 of this Loan Agreement may no longer be accurate
or that any other violation of the foregoing Requirements of Law has occurred or
is being investigated by Governmental Authorities. In connection with such an
event, Borrower shall comply with all

                                                              Ply Gem Industries

                                     - 50 -
<PAGE>
Requirements of Law and directives of Governmental Authorities and, at Lender's
request, provide to Lender copies of all notices, reports and other
communications exchanged with, or received from, Governmental Authorities
relating to such event. Borrower shall also reimburse Lender for any expense
incurred by Lender in evaluating the effect of such an event on the Loan and
Lender's interest in the collateral for the Loan, in obtaining any necessary
license from Governmental Authorities as may be necessary for Lender to enforce
its rights under the Loan Documents, and in complying with all Requirements of
Law applicable to Lender as the result of the existence of such an event and for
any penalties or fines imposed upon Lender as a result thereof.

                    NO TRANSFER OR ENCUMBRANCES; DUE ON SALE

      10.01. Prohibition Against Transfers. Borrower shall not permit any
Transfer to be undertaken or cause any Transfer to occur other than a Permitted
Transfer. Any Transfer made in violation of this Loan Agreement shall be void.

      10.02. Lender Approval.

            (a) Lender's decision to approve any Transfer proposed by Borrower
shall be made in Lender's sole discretion and Lender shall not be obligated to
approve any Transfer. Notwithstanding the foregoing, Lender will not
unreasonably withhold its consent two (2) times during the term of the Loan to a
transfer or sale (but not a pledge, mortgage, assignment, encumbrance or other
transfer as security for an obligation) of the Property and Borrower's
obligations under the Loan Documents, provided Borrower satisfies all of the
conditions set forth in this Section 10.02. Borrower agrees to supply all
information Lender may request to evaluate a Transfer, including, without
limitation,information regarding the proposed transferee's ownership
structure, financial condition and management experience for comparable
properties. Borrower acknowledges that Lender may impose conditions to its
approval of a Transfer, including, without limitation, (i) no Event of Default,
or an event which with the giving of notice or lapse of time or both could
become an Event of Default, has occurred and is continuing, or no default under
the Ply Gem Lease has occurred and is continuing, (ii) approval of the proposed
transferee's ownership structure, financial condition and management experience
for comparable properties, (iii) payment of an assumption fee equal to one
percent (1%) of the outstanding principal balance of the Loan, except that with
respect to any Transfer of the Property to an Affiliate of Borrower, the
assumption fees shall be waived, (iv) adding guarantors or changing the scope of
the Guaranty, (v) assumption in writing (acceptable to Lender in its sole
discretion) by the transferee and a guarantor (which guarantor must be
acceptable to Lender in its sole discretion) of all obligations of the
transferor and the Guarantor under the Loan Documents and execution and delivery
of such other documentation as may be required by Lender and the Rating
Agencies, (vi) delivery of a new substantive consolidation opinion, a tax
opinion and other applicable opinions as required by Lender and the Rating
Agencies, (vii) adjusting amounts

                                                              Ply Gem Industries

required for the Reserve Accounts, and (viii) obtaining Rating Confirmations if
a Securitization has occurred. In connection with such transfer, if a transferee
of creditworthiness acceptable to Lender, in its sole discretion, assumes all
obligations of Corporate Property Associates 16 Global Incorporated pursuant to
an assumption agreement and executes an Environmental Indemnity and Guaranty of
Recourse Obligations of Borrower acceptable to Lender in its sole discretion,
then from and after the date of such assignment, Lender shall release Corporate
Property Associates 16 Global Incorporated from all obligations thereafter
accruing under the Loan Documents, but not for obligations under the Loan
Documents which accrued prior to the date of the transfer.

            (b) Notwithstanding any provision of this Article 10 to the
contrary, and provided that no Event of Default has occurred and is continuing
under the Loan Documents, Borrower and Corporate Property Associates 16 Global
Incorporated shall be permitted at any time and from time to time to transfer or
convey (through merger or otherwise) their interests in Borrower and Borrower
shall be entitled to transfer the Property, as applicable, to any Affiliate of
either of them, provided that following the transfer any new guarantor or
guarantors shall satisfy the Net Worth Requirement, without payment of any
prepayment or transfer fee so long as such transfer does not result in a
downgrade, qualification or withdrawal of the Securities and provided that any
transferee of the Property is a single purpose, bankruptcy remote entity (based
upon Lender's review of the transferee's organizational structure, and as
evidenced by a non-consolidation opinion to be delivered at Lender's request and
in form and substance reasonably acceptable to Lender). As used herein, the term
"AFFILIATE" refers to another W.P. Carey Parent (as hereinafter defined) or to
an entity which controls, is controlled by or is under common control with
Corporate Property Associates 14 Incorporated, Corporate Property Associates 15
Incorporated, Corporate Property Associates 12 Incorporated, or their
successors, or the Guarantor or any other funds which is a member of the W.P.
Carey family of funds (each, a "W.P. CAREY PARENT"). In connection with the
transfer of the Property or interests in Borrower to any Affiliate, if the W.P.
Carey Parent of such Affiliate (i) assumes all of the obligations of Corporate
Property Associates 16 Global Incorporated pursuant to an assumption agreement
satisfactory to Lender, in its sole discretion, which assumption agreement
provides, among other things for the assumption of all liabilities of whatever
nature in connection with the Loan accruing from and after the date of such
transfer, and for waivers of any and all defenses in connection with such
liabilities and obligations under the Loan Documents and in connection with the
assumption and (ii) such transferee delivers to Lender an opinion of counsel as
to the enforceability of such assumption and the waivers of defenses thereunder,
and a non-consolidation opinion, each in form and substance satisfactory to
Lender, in its sole discretion, then upon such transfer, Lender shall release
Corporate Property Associates 16 Global Incorporated from all liabilities under
the Loan Documents which arise with respect to matters that occur after, but not
prior to, such transfer, and (iii) the new W.P. Carey Parent satisfies the Net
Worth Requirement. Borrower agrees to pay all of Lender's expenses incurred in
connection with reviewing and documenting a Transfer (including, without
limitation, the costs of obtaining Rating Confirmations if required), which
amounts must be paid by Borrower whether or not the proposed Transfer is
approved, if approval is required. Upon Borrower's

                                                              Ply Gem Industries

failure to pay such amounts, and in addition to Lender's remedies for Borrower's
failure to perform, the unpaid amounts shall be added to principal, shall bear
interest at the Default Rate until paid in full, and payment of such amounts
shall be secured by the Security Instrument and other collateral given to secure
the Loan.

      10.03. Borrower Right to Partial Releases.

            (a) Right to Release. After the Open Date, Borrower shall have the
right, from time to time, to obtain a partial release ("PARTIAL RELEASE") of a
Release Property from the Security Instrument, Assignment of Leases and Rents
and related UCC financing statements. Borrower must provide at least thirty
(30), but no more than sixty (60) days prior written notice to Lender requesting
a Partial Release and identifying the Release Property and date upon which it
desires to have the Release Property released ("PARTIAL RELEASE DATE"). Prior to
Lender's agreement to a Partial Release, each of the following conditions must
be satisfied to Lender's reasonable satisfaction:

                  (i) No Event of Default shall have occurred and be continuing
at the time Borrower requests a Partial Release or on the Partial Release Date.

                  (ii) On or before the Partial Release Date, Borrower shall
deliver to Lender the Defeasance Collateral in an amount calculated on
the basis of the Partial Release Price allocated to the Release Property.

                  (iii) As of the Partial Release Date, and after giving effect
to the Partial Release to occur on such date the Loan to Value Ratio for the
remaining Property is no more than sixty-five percent (65%), as determined by
Lender.

                  (iv) As of the Partial Release Date, and, after giving effect
to the Partial Release to occur on such date, the Debt Service Coverage Ratio
for the remaining Property is at least 1.20:1.00 for the twelve (12) month
period immediately preceding the Partial Release with respect to the Remaining
Property after giving effect to the Partial Release; all as determined by Lender
in its sole discretion.

                  (v) Borrower has delivered to Lender forms of all documents
necessary to release the Release Property from the liens created by the Security
Instrument, Assignment of Rents and Leases and related UCC financing statements,
each in appropriate form required by the state in which the Release Property is
located and otherwise satisfactory to Lender in all respects.

                  (vi) Borrower shall deliver to Lender confirmation, in form
and substance satisfactory to Lender, that all conditions of partial Defeasance
have been met from any applicable Rating Agency that has required as a condition
to such partial Defeasance that such conditions have been met.

                                                              Ply Gem Industries

<PAGE>
                  (vii) Borrower has complied with the terms and conditions of
this Article 10 and Section 2.05 hereof, satisfactory to Lender in all respects.

                  (viii) Borrower has delivered a certificate from a Responsible
Officer certifying that the requirements set forth in this Section 10.03 have
been satisfied in all material respects.

                  (ix) Borrower has paid all amounts then due and unpaid under
the Loan Documents through (and including) amounts due on the Release Date and
in connection with the Partial Release.

                  (x) Lender shall have received a copy of a deed conveying all
of Borrower's right, title and interest in and to the Release Property to an
entity other than Borrower and any SPE Equity Owner and a letter from Borrower
countersigned by a title insurance company acknowledging receipt of such deed
and agreeing to record such deed in the real estate records of the appropriate
recording office in which the Release Property is located.

            (b) Reimbursement of Lender Expenses. Borrower agrees to pay all of
Lender's expenses incurred in connection with reviewing and documenting such
Partial Release (including, without limitation, the costs of obtaining Rating
confirmations if required by Lender), which amounts must be paid by Borrower
whether or not the proposed Partial Release is approved or executed. Upon
Borrower's failure to pay such amounts, and in addition to Lender's remedies for
Borrower's failure to perform, the unpaid amounts shall be added to principal,
shall bear interest at the Default Rate until paid in full and payment of such
amounts shall be secured by the Security Instrument and other collateral given
to secure the Loan.

            (c) Liens of Security Instrument Otherwise Unaffected. No Partial
Release granted by Lender shall, in any way, impair or affect the lien or
priority of the Security Instrument relating to the portion of the Property not
included in the Partial Release or improve the position of any subordinate
lienholder with respect thereto, except to the extent that the obligations
hereunder shall have been reduced by the actual monetary consideration, if any,
received by Lender for such Partial Release. This Security Instrument shall
continue as a Lien and security interest on the portion of the Property not
included in a Partial Release.

      10.04 Other Releases of the Mortgaged Property. In addition to the rights
granted to Borrower under Section 10.03 with respect to the Release Properties,
Lender may release other portions of the Property for such consideration and
upon such conditions as Lender may require without, as to the remainder of the
Property, in any way impairing or affecting the Lien or priority of the Security
Instrument or improving the position of any subordinate lienholder with respect
thereto, except to the extent that the obligations hereunder shall have been
reduced by the actual monetary consideration, if any, received by Lender for
such release, and Lender may accept by assignment, pledge or otherwise any other
property in place thereof as Lender may require without being accountable for so
doing to any other lienholder. Notwithstanding

                                                              Ply Gem Industries

                                      -54-
<PAGE>

anything to the contrary herein, Borrower shall have no right to request and
Lender shall have no obligation to grant its consent to any release pursuant
this Section 10.04.

      10.05. OFAC Compliance; Substantive Consolidation Opinion. Notwithstanding
anything to the contrary contained in this Section 10, (a) no transfer (whether
or not such transfer shall constitute a Transfer) shall be made to any Person on
the OFAC list and (b) in the event any transfer (whether or not such transfer
shall constitute a Transfer) results in any Person owning in excess of
forty-nine percent (49%) of the ownership interest Borrower or any SPE Equity
Owner, Borrower shall, prior to such transfer, deliver a new substantive
consolidation opinion letter with respect to the new equity owners which is
acceptable in all respects to Lender and to the Rating Agencies if a
Securitization has occurred.

made during the term of the Loan shall have been false or misleading in any
material respect as of the date made and results in a material adverse effect or
Lender's sole discretion may result in a material adverse effect;

legal action to recover any sums as the same become due, without regard to
whether or not the Loan shall be accelerated and without prejudice to Lender's
right thereafter to accelerate the Loan or exercise any other remedy, if such
sums remain uncollected.

            (c) Foreclosure. Lender may institute proceedings, judicial or
otherwise, for the complete or partial foreclosure of the Security Instrument or

all powers permitted by law which may be necessary or usual in such cases for
the protection, procession, control, management and operation of the Property.
Borrower hereby consent, to the extent permitted under applicable law, to the
appointment of a

                                                              Ply Gem Industries

receiver or trustee of the Property upon Lender's request if an Event of
Default has occurred. At Lender's option, such receiver or trustee shall serve
without any requirement of posting a bond.

            (e) Recovery of Possession. Subject to the Requirements of Law and
the rights of Ply Gem under the Ply Gem Lease or the rights of any Acceptable
Replacement Tenant under an Acceptable Replacement Lease, Lender may enter into
or upon the Property, either personally or by its agents, and dispossess and
exclude Borrower and its agents and servants therefrom (without liability for
trespass, damages or otherwise), and take possession of all books, records and
accounts relating to the Property, and Borrower agrees to surrender possession
of the Property and all other Property, including without limitation, all
documents, books, records and accounts relating to the Property, to Lender upon
demand. As a mortgagee-in-possession of the Property, Lender shall have all
rights and remedies permitted by law or in equity to a mortgagee-in-possession,
including, without limitation, the right to charge Borrower the fair and
reasonable rental value for Borrower's use and occupation of any part of the
Property that may be occupied or used by Borrower and the right to exercise all
rights and powers of Borrower with respect to the Property, whether in the name
of Borrower or otherwise (including, without limitation, the right to make,
cancel, enforce or modify Leases (provided, however, that Lender shall not,
prior to completion of foreclosure, agree to any reduction of rent under the Ply
Gem Lease or any Acceptable Replacement Lease, modify the term of the Ply Gem
Lease or any Acceptable Replacement Lease, or cancel or terminate the Ply Gem
Lease or any Acceptable Replacement Lease unless Ply Gem or any Acceptable
Replacement Tenant is in default beyond any applicable cure period), obtain and
evict tenants, and demand, sue for, collect and receive all Rents of the
Property).

            (f) UCC Remedies. Lender may exercise with respect to the Property,
each right, power or remedy granted to a secured party under the UCC, including,
without limitation, (i) the right to take possession of the Property and to take
such other measures as Lender deems necessary for the care, protection and
preservation of the Property, and (ii) the right to require that Borrower, at
its expense, assemble the Property and make it available to Lender at a
convenient place acceptable to Lender. Any notice of sale, disposition or other
intended action by Lender with respect to the Property sent to Borrower in
accordance with the provisions hereof at least ten (10) days prior to such
action, shall constitute reasonable notice to Borrower. Lender shall not have
any obligation to clean-up or otherwise prepare the Property for sale.

            (g) Apply Funds in Reserve Accounts. Lender may apply any funds then
deposited in any or all of the Reserve Accounts and or otherwise held in escrow
or reserve (except to the extent that such sums belong to Ply Gem and the terms
of the Ply Gem Lease do not permit Borrower, as landlord, to utilize such sums)
by Lender under the Loan Documents (including without limitation Restoration
Proceeds) as a credit on to Loan, in such priority and proportion as Lender
deems appropriate.

            (h) Insurance Policies. Lender may surrender any or all insurance
policies maintained as required by this Loan Agreement, unless such policies
then belong to Ply Gem,

                                                              Ply Gem Industries

                                     - 59 -
<PAGE>
collect the unearned Insurance Premiums and apply such sums as a credit on the
Loan, in such priority and proportion as Lender deems appropriate. Borrower
hereby appoints Lender its attorney-in-fact with full power of substitution (and
which shall be deemed to be coupled with an interest and irrevocable until the
Loan is paid and the Security Instrument is discharged of record, with Borrower
hereby ratifying all that its said attorney shall do by virtue thereof) to
surrender such insurance policies and collect such Insurance Premiums.

            (i)   Protection of Lender's Security and Right to Cure. Lender may,
without releasing Borrower from any obligation hereunder or waiving the Event of
Default, perform the obligation which Borrower failed to perform in such manner
and to such extent as Lender deems necessary to protect and preserve the
Property and Lender's interest therein, including without limitation (i)
appearing in, defending or bringing any action or proceeding with respect to the
Property, in Borrower's name or otherwise; (ii) making repairs to the Property
or completing improvements or repairs in progress; (iii) hiring and paying legal
counsel, accountants, inspectors or consultants; and (iv) paying amounts which
Borrower failed to pay. Amounts disbursed by Lender shall be added to the Loan,
shall be immediately due and payable, and shall bear interest at the Default
Rate from the date of disbursement until paid in full.

            (j)   Violation of Laws. If the Property is not in compliance with
all Requirements of Laws, Lender may impose additional requirements upon
Borrower in connection with such Event of Default including, without limitation,
monetary reserves or financial equivalents.

      11.03 Cumulative Remedies; No Waiver; Other Security. Lender's remedies
under this Loan Agreement are cumulative (whether set forth in this Article 11
or in any other section of this Loan Agreement) with those in the other Loan
Documents and otherwise permitted by law or in equity and may be exercised
independently, concurrently or successively in Lender's sole discretion and as
often as occasion therefor shall arise. Lender's delay or failure to accelerate
the Loan or exercise any other remedy upon the occurrence of an Event of Default
shall not be deemed a waiver of such right as remedy. No partial exercise by
Lender of any right or remedy will preclude further exercise thereof, Notice or
demand given to Borrower in any instance will not entitle Borrower to notice or
demand in similar or other circumstances (except where notice is expressly
required by this Loan Agreement to be given) nor constitute Lender's waiver of
its right to take any future action in any circumstance without notice or
demand. Lender may release security for the Loan, may release any party liable
therefor, may grant extensions, renewals or forbearances with respect thereto,
may accept a partial or past due payment or grant other indulgences, or may
apply any other security held by it to payment of the Loan, in each case without
prejudice to its rights under the Loan Documents and without such action being
deemed an accord and satisfaction or a reinstatement of the Loan. Lender will
not be deemed as a consequence of its delay or failure to act, or any
forbearance granted, to have waived or be estopped from exercising any of its
rights or remedies.
                                                              Ply Gem Industries

      11.04 Enforcement Costs. Borrower shall pay, on written demand by Lender
all costs incurred by Lender in (a) collecting any amount payable under the Loan
Documents, or (b) enforcing its rights under the Loan Documents, in each case
whether or not legal proceedings are enforcing its rights under the Loan
Documents, in each case whether or not legal proceedings are commenced or
whether legal action of pursued to final judgment. Such fees and expenses
include, without limitation, reasonable fees for attorneys, paralegals, law
clerks and other hired professionals, a reasonable assessment of the cost of
services performed by Lender's default management staff, court fees, costs
incurred in connection with pre-trial, trial and appellate level proceedings,
including discovery, and costs incurred in post-judgment collection efforts or
in any bankruptcy proceeding. Amounts incurred by Lender shall be added to
principal, shall be immediately due and payable, shall bear interest at the
Default Rate from the date of disbursement until paid in full, if not paid in
full within five (5) days after Lender's written demand for payment, and such
amounts shall be secured by the Security Instrument and other collateral given
to secure the Loan.

      11.05 Application of Proceeds. The proceeds from disposition of the
Property shall be applied by Lender as a credit to the Loan and to recovery or
reimbursement of the costs of enforcement (contemplated by Section 11.04 above)
in such priority and proportion as Lender determines appropriate.

      11.06 Cross-Default; Cross-Collateralization; Waiver of Marshalling of
Assets.

            (a)   Borrower acknowledges that Lender has made the Loan to
Borrower upon the security of its collective interest in the Property and in
reliance upon the aggregate of the Property taken together being of greater
value as collateral security than the sum of each Individual Property taken
separately. Borrower agrees that the Security Instruments are and will be cross-
collateralized and cross-defaulted with each other so that (i) an Event of
Default under any of the Security Instrument shall constitute an Event of
Default under each of the other Security Instrument which secure the Note; (ii)
an Event of Default under the Note or this Loan Agreement shall constitute an
Event of Default under each Security Instrument; (iii) each Security Instrument
shall constitute security for the Note as if a single blanket lien were placed
on all of the Properties as security for the Note; and (iv) such cross-
collateralization shall in no event be deemed to constitute a fraudulent
conveyance.

            (b)   To the fullest extent permitted by law, Borrower, for itself
and its successors and assigns, waives all rights to a marshalling of the assets
of Borrower, Borrower's partners and others with interests in Borrower, and of
the Property, or to a sale in inverse order of alienation in the event of
foreclosure of all or any of the Security Instruments, and agrees not to assert
any right under any laws pertaining to the marshalling of assets, the sale in
inverse order of alienation, homestead exemption, the administration of estates
of decedents, or any other matters whatsoever to defeat, reduce or affect the
right of Lender under the Loan Documents to a sale of the Property for the
collection of the Debt without any prior or different resort for collection or
of the right of Lender to the payment of the Debt out of the net proceeds of the
Property in preference to every other claimant whatsoever. In addition,
Borrower, for itself and its

                                                              Ply Gem Industries
                                      -61-
<PAGE>
 successors and assigns, waives in the event of foreclosure of any or all of the
Security Instruments, any equitable right otherwise available to Borrower which
would require the separate sale of the Property or require Lender to exhaust its
remedies against any Individual Property or any combination of the Property
before proceeding against any other Individual Property or combination or
Property; and further in the event of such foreclosure Borrower does hereby
expressly consents to and authorizes, at the option of Lender, the foreclosure
and sale either separately or together of any combination of the Property.

      12.01. Nonrecourse Obligation. Except as otherwise provided in this

the Loan and performance of Borrower's obligations under the Loan Documents and

thereof becomes an asset in a voluntary bankruptcy or other insolvency
proceeding; (b) Borrower or SPE Equity Owner commences a bankruptcy or other
insolvency proceeding; (c) an involuntary bankruptcy or other insolvency

violation of the Loan Documents limited, however, to $5,883,333.000;

            (f) Damage to or loss of all or any part of the Property as a result

                                   ARTICLE 13
                                 INDEMNIFICATION

      13.01. Indemnification Against Claims. Borrower shall indemnify, defend,
release and hold harmless Lender and each of the other Indemnified Parties from
and against any and all Losses directly or indirectly arising out of, or in any

or loss of, or damage to, property occurring in, on or with respect to the
Property or on the adjoining sidewalks, curbs, adjacent property or adjacent
parking areas, streets or ways or otherwise arising with respect to the use of
the Property;(b)failure of the Property to be in compliance with any
Requirements of Law; (c) breach or default of Borrower's representations or
obligations under Sections 8.27, 8.28 or 9.16 of this Loan Agreement; (d) any

discharge the lessor's agreements contained in any Lease, unless such
undertakings are in writing and signed by Lender; (e) breach or default under
the ERISA obligations set forth in Sections 8.26 and 9.15 of this Loan Agreement
(including, without limitation, legal fees and costs incurred in the

individual prohibited transaction exemption under ERISA that may be required, in
Lender's sole discretion); or (f) any claim, litigation, investigation or
proceeding commenced or threatened relating to any of the foregoing, whether or
not Indemnified party is a party thereto; provided, however, any such indemnity
shall not apply to any Indemnified Party to the extent any such Losses arise

"INDEMNIFIED CLAIMS").

13.02. Duty to Defend. If an Indemnified Party claims indemnification under this
Loan Agreement, the Indemnified Party shall promptly notify Borrower of the
Indemnified claim. After notice by any Indemnified party,Borrower shall defend

Indemnified Party, in the name of the Indemnified

                                                              Ply Gem Industries

Party) by attorneys and other professionals reasonably approved, in writing, by
the Indemnified Party. Notwithstanding the foregoing, any Indemnified Party may,
in its sole discretion and at the expense of Borrower, engage its own attorneys
and other professionals to defend or assist it if such Indemnified Party
determines that the defense as conducted by Borrower is not proceeding or being
conducted in a satisfactory manner or that a conflict of interest exists between
any of the parties represented by Borrower's counsel in such action or
proceeding. Within five (5) business days of Indemnified Party's demand,
Borrower shall pay or, in the sole discretion of the costs and expenses
(including, without limitation, reasonable attorney fees, engineer fees,
environmental consultant fees, laboratory fees and other professionals in
connection therewith) Default Rate until paid in full and payment of such

                                   ARTICLE 14
                        SUBROGATION; NO USURY VIOLATIONS

      14.01. Subrogation. If the Loan is used to pay, satisfy, discharge, extend
or renew any indebtedness secured by a pre-existing mortgage, deed of trust or
other Lien encumbering the Property, then to the extent of funds so used, Lender
shall automatically, and without further action on its part, be subrogated to
all rights, including lien priority, held by the holder of the indebtedness
secured by such prior Lien, whether or not the prior Lien is released, and such
former rights are not waived but rather are continued in full force and effect
in favor of Lender and are merged with the Liens created in favor of Lender as
security for payment of the Loan and performance of the Obligations.

      14.02. No Usury. At no time is Borrower required to pay interest on the
Loan or on any other payment due hereunder or under any of the other Loan
Documents (or to make any other payment deemed by law or by a court of competent
jurisdiction to be interest) at a rate which would subject Lender either to
civil or criminal liability as a result of being in excess of the maximum
interest rate which Borrower is permitted by applicable law to pay. If interest
(or such other amount deemed to be interest) paid or payable by Borrower is
deemed to exceed such maximum rate, then the amount to be paid immediately shall
be reduced to such maximum rate and thereafter computed at such maximum rate.
All previous payments in excess of such maximum rate shall be deemed to have
been payments of principal (in inverse order of maturity) and not on account of
interest due hereunder. For purposes of determining whether any applicable usury
law has been violated, all payments deemed by law or a court of competent
jurisdictions to be interest shall, to the extent permitted any applicable law,
be deemed to be amortized, prorated, allocated and spread over the full term of
the Loan in such manner so that interest is computed at a rate throughout the
full term of the Loan which does not exceed the maximum lawful rate of interest.

                                                              Ply Gem Industries

                         SALE OR SECURITIZATION OF LOAN

      15.01. Splitting the Note. Lender has the right, from time to time, to
sever the Note into one or more separate promissory notes, each secured by all
of the Property, in such denominations as Lender determines in its sole
discreation (including the creation of a mezzanine loan secured by a collateral
assignment of the equity interest in Borrower and SPE Equity Owner) which
promissory notes may be included in separate sales or securitizations undertaken
by Lender. In conjunction with any such action, Lender may redefine the interest
rate and amortization schedule; provided, however: (a) if Lender redefines the
interest rate, the initial weighted average of the interest rates contained in
the severed promissory notes taken in the aggregate shall equal the Applicable
Interest Rate, and (b) if Lender redefines the amortization schedule, the
amortization of the severed promissory notes taken in the aggregate shall
require no more amortization to be paid under the Loan than as required under
this Loan Agreement and the Note at the time such action was taken by Lender.
Subject to the foregoing each severed promissory note, and the Loan evidenced
thereby, shall be upon all of the terms and provisions contained in this Loan
Agreement and the Loan Documents which continue in full force and effect.
Borrower, at Borrower's expense, agrees to cooperate with all reasonable
requests of Lender to accomplish the foregoing, including, without limitation,
execution and prompt delivery to Lender of a severance agreement and such other
documents as Lender shall reasonably require, provided that no such agreement
may allocate specific collateral given for the Loan as security for performance
of specific promissory notes and no separate servicer may be assigned for any
separate notes. Borrower hereby appoints Lender its attorney-in-fact with full
power of substitution (and which shall be deemed to be coupled with an interest
and irrevocable until the Loan is paid and the Security Instrument is discharged
of record, with Borrower hereby ratifying all that its said attorney shall do by
virtue thereof) to make and execute all documents necessary or desirable to
effect the aforesaid severance; provided, however, Lender shall not make or
execute any such documents under such power until five (5) days after written
notice has been given to Borrower by Lender of Lender's intent to exercise its
rights under such power. Borrower's failure to deliver any of the documents
requested by Lender hereunder for a period of ten (10) business days after such
notice by Lender shall, at Lender's option, constitute an Event of Default
hereunder.

      15.02. Lender's Rights to Sell or Securitize. Borrower acknowledges that
Lender, and each successor to Lender's interest, may (without prior notice to
Borrower or Borrower's prior consent), sell or grant participations in the Loan
(or any part thereof), sell or subcontract the servicing rights related to the
Loan, Securitize the Loan or include the Loan as part of a Securitization and,
in connection therewith, assign Lender's rights hereunder to a securitization
trustee. Borrower, at its expense, agrees to cooperate with all reasonable
requests of Lender in connection with any of the foregoing including, without
limitation, executing any financing statements or other documents deemed
necessary by Lender or its transferee to create, perfect or preserve the rights
and interest to be acquired by such transferee, provide any updated financial
information with appropriate verification through auditors letters, revised
organizational

                                                              Ply Gem Industries

                                     - 66 -
<PAGE>

documents and counsel opinions satisfactory to the Rating Agencies, and executed
amendments to the Loan Documents, and review information contained in a
preliminary or final private placement memorandum, prospectus, prospectus,
supplements or other disclosure documents, providing a mortgagor estoppel
certificate and such other information about Borrower, SPE Equity Owner, any
Guarantor or the Property as Lender may require for Lender's offering materials.

      15.03. Dissemination of Information. Borrower acknowledges that Lender may
provide to third parties with an exiting or prospective interest in the
servicing, enforcement, evaluation, performance, ownership, purchase,
participation, or Securitization of the Loan, including, without limitation, any
Rating Agency and any entity maintaining databases on the underwriting and
performance of commercial mortgage loans, any and all information which Lender
now has or may hereafter acquire relating to the Loan, the Property, Borrower,
SPE Equity Owner or any Guarantor, as Lender determines necessary or desirable
and that such information may be included in disclosure documents in connection
with a Securitization or syndication of participation interests, including,
without limitation, a prospectus, prospectus supplement, offering memorandum,
private placement memorandum or similar document (each, a "DISCLOSURE DOCUMENT")
 and also may be included in filing with the Securities and Exchange
Commission pursuant to the Securities Act on the Securities Exchange Act. To the
fullest extent permitted under applicable law, Borrower irrevocably waives all
rights, if any, to prohibit such disclosure, including, without limitation, any
right of privacy.

      15.04. Reserves Accounts. If the Loan is made a part of a Securitization,
Borrower acknowledges that all funds held by Lender in the Reserve Accounts in
accordance with this Loan Agreement or the other Loan Documents shall be
deposited in "eligible accounts" at "eligible institutions" or invested in
"permitted investments" as then defined and required by the Rating Agencies, and
this Loan Agreement will automatically be amended to so provide.

      15.05. Securitization Indemnification. Borrower agrees to provide in

                                 LENDER CONSENT

      17.01.No Joint Venture; No Third Party Beneficiaries. Borrower and Lender
intend that the relationships created hereunder and under each of the other Loan
Documents are solely those of borrower and lender. Nothing herein or in any of
the other Loan Documents is intended to create, nor shall it be construed as
creating anything but a debtor-creditor relationship between Borrower and Lender
nor shall they be deemed to confer on anyone other than Lender, and its
successors and assigns, any right to insist upon or to enforce the performance
or observance of any of the obligations contained herein or therein.

     17.02. Lender Approval. Wherever pursuant to a Loan Document (a) Lender
exercises any right to approve or disapprove or to grant or withhold consent;
(b) any arrangement or term is to be satisfactory to Lender; (c) a waiver is
requested from Lender, or (d) any other decision is to be made by Lender, all
shall be made in Lender's sole discretion, unless expressly provided otherwise
in such Loan Document. By approving or granting consent, accepting performance
from Borrower, or releasing funds from a Reserve Account, Lender shall not be
deemed to have

                                                             Ply Gem Industries

                                     - 70 -
<PAGE>


warranted or affirmed the sufficiency, completeness, legality or effectiveness
of the subject matter or of Borrower's compliance with Requirements of Laws.
Notwithstanding any provision under the Loan Documents which provides Lender the
approve or disapprove any action or decision by Borrower, Lender is not thereby
opportunity to undertaking the performance of any obligation of Borrower under
any of the Loan Documents or any of the other documents and agreements in
connection with this transaction(including, without limitation, the Leases).

      17.03. Performance at Borrower's Expense. Borrower acknowledges and
agrees that in connection with each request by Borrower to: (a) modify or waive
any provision of the Loan Documents; (b) release or substitute Property; (c)
obtain Lender's approval or consent whenever required by the Loan Documents
including, without limitation, review of a Transfer request, matters affecting a
Major Lease, improvements or alterations to the Property, and easements or other
additions to Permitted Encumbrances; or (d) provide a subordination,
non-disturbance and attornment agreement, Lender reserves the right to collect
a review or processing fee from Borrower based on a reasonable estimate of the
administrative costs which lender will incur to connection therewith. Borrower
agrees to pay such fee along with all reasonable legal fees and expenses
incurred by Lender and the fees required for a Rating Confirmation or approval
from the trustee if the Loan has been Securitized, as applicable, irrespective
of whether the matter is approved, denied or withdrawn. Any amounts payable by
Borrower hereunder, shall be deemed a part of the Loan, shall be secured by this
Loan Agreement and shall bear interest at the Default Rate if not fully paid
within ten (10) days of written demand for payment.

      17.04. Non-Reliance. Borrower agrees that any diligence or
investigation performed by or on behalf of Lender in underwriting or servicing
the Loan (including, without limitation, information obtained about the Property
the Borrower or its equity investors or affiliates) does not in any respect
limit or excuse any of Borrower's representations, warranties, covenants or
agreements set forth in this Loan Agreement or any of the other Loan Documents.
The fact that Lender has performed diligence does not affect Lender's ability or
right to rely fully upon the representations, warranties , covenants and
agreements made by Borrower in the Loan Documents or to pursue any available
remedy for a breach thereof. If Lender delivers or has delivered to Borrower
(or to Borrower's agents, equity investors or representatives) any information
obtained or developed by Lender relating to the Loan, the Property or Borrower,
Borrower acknowledges and agrees that such information has been delivered for
informational purposes only and Lender has no liability of responsibility to
Borrower with respect to such information, including, without limitation, the
completeness or accuracy of any such information. No due diligence consultant
engaged by Lender is or shall deemed an agent of Lender.

agreement even though all signatures do not appear on the same document.

      18.05. Unenforceable Provisions. Any provision of this Loan Agreement or
any other Loan Documents which is determined by a court of competent
jurisdiction or government body to be invalid, unenforceable or illegal shall be

                                   ARTICLE 19
                            SUBSTITUTION OF PROPERTY

      19.01. Substitution of Properties. Subject to the terms of this Section,
Borrower may obtain a release of the lien of the Property-related Loan Documents
from up to three (3) parcels constituting the Property (the "RELEASE PROPERTY"),
which constitute in the aggregate, not more than thirty percent (30%) of the
total cash flow of the Property, by substituting therefor an office and/or
industrial property of like quality to be owned by a subsidiary of the Guarantor
(a "SUBSTITUTE PROPERTY"), provided that the following conditions precedent are
satisfied.

            (a)   Lender shall have received at least sixty (60) days prior
written notice requesting the substitution and identifying the Substitute
Property and Release Property.

            (b)   Lender shall have received (i) a copy of a deed conveying all
of Borrower's right, title and interest in and to the Release Property to a
Person other than Borrower or any principal or affiliate of Borrower pursuant
to an arms length transaction, and (ii) a letter from Borrower countersigned by
a title insurance company acknowledging receipt of such deed and agreeing to
record such deed in the real estate records for the county or town (as
applicable) in which the Release Property is located simultaneously with the
substitution.

            (c)   Lender shall have received a current M.A.I. appraisal of the
Release Property, the Substitute Property and the Remaining Property
(hereinafter defined) in form and substance meeting the standards of prudent
institutional lenders prepared within six (6) months prior to the release and
substitution (i) showing as to the Substitute Property an appraised value equal
to or greater than the appraised value of the Release Property as of the
original closing date of the Loan, and (ii) which supports a post-substitution,
aggregate loan-to-value ratio, for all properties that will secure the Loan
after the substitution, that does not exceed the lesser of (A) the aggregate
loan-to-value ratio for the properties securing the Loan as of the original
closing date of the Loan or (B) the aggregate loan-to-value ratio of such
properties immediately prior to the date of the proposed substitution.

                                                              Ply Gem Industries
                                      -74-
<PAGE>


         (d) RESERVED.

         (e) Lender shall have received a certificate of Borrower, together with
all supporting financial information and other documentation satisfactory to
Lender, certifying that, after the substitution (i) with respect to any
Remaining Property which shall continue to secure the Loan, the debt service
coverage ratio for the twelve (12) months immediately preceding the closing date
of the substitution (as determined by Lender in its sole discretion) shall be
equal to or greater than the debt service coverage ratio for such Remaining
Property (excluding the Substitute Property) during the twelve (12) months
immediately preceding the original closing date of the Loan, and (ii) with
respect to the Substitute Property, the debt service coverage ratio for the
twelve (12) months immediately preceding the date of the substitution (as
determined by Lender in its sole discretion) shall be equal to or greater than
the corresponding debt service coverage ratio for the Release Property during
the twelve (12) months  immediately  preceding the closing date of the
substitution, such that the aggregate debt service coverage ratio for all
properties securing the Loan prior to the substitution shall remain unchanged
upon the closing date of the substitution notwithstanding the substitution of
property securing the Loan. In the event that trailing twelve (12) month net
operating income for the Substitution Property is not available, Lender agrees
to base its determination of compliance with this subsection (e) upon the best
available financial information for the Substitute Property by estimating an
underwritten net cash flow amount to be used in lieu of trailing twelve (12)
month Net Operating Income.

         (f) Lender shall have received, at the sole cost and expense of
Borrower, (i) confirmation in writing from the Rating Agencies to the effect
that such release and  substitution  will not result in a  withdrawal,
qualification or downgrade of the respective ratings in effect immediately prior
to such release and substitution of the Securities issued in connection with the
Securitization, and (ii) the consent of the servicer of the Loan, which consent
shall not be unreasonably withheld or delayed. If the Loan is not part of a
Securitization, Lender shall have consented in writing to such release and
substitution, which consent shall be given in Lender's reasonable discretion
applying the standard of a prudent institutional lender with respect to a Loan
of similar size to be secured by real estate collateral of similar size, scope
and value of the Substitute Property.

         (g) No Event of Default shall have occurred and be continuing under the
Note, this Loan Agreement or the other Loan Documents and Borrower shall be in
compliance in all material respects with all of the terms and conditions set
forth in this Loan Agreement and in each other Loan Document. Lender shall have
received a certificate from Borrower,  in form and substance reasonably
satisfactory to Lender and the Rating Agencies, confirming the foregoing,
stating that the representations and warranties of Borrower contained in this
Loan Agreement and the other Loan Documents are true and correct in all material
respects on and as of the data of the release and substitution with respect to
Borrower, the Remaining Property and the Substitute Property and containing any
other representations and warranties with respect to Borrower, the Properties
and the Substitute Property, such certificate to be in form and substance
satisfactory to Lender or the Rating Agencies, as applicable.

                                                              Ply Gem Industries

      (h) Borrower shall (A) have executed, acknowledged and delivered to Lender
(i) a Security Instrument, an Assignment of Leases and Rents and two UCC-1
Financing Statements with respect to the Substitute Property and the Borrower,
together with a letter from Borrower countersigned by a title insurance company
acknowledging receipt of such Security Instrument, Assignment of Leases and
Rents and UCC-1 Financing Statements and agreeing to record or file, as
applicable, such Security Instrument, Assignment of Leases and Rents and one of
the UCC-1 Financing Statements in the real estate records for the county or town
(as applicable) in which the Substitute Property is located and to file one of

described above is available or, if such endorsement is not available, in an
amount equal to one hundred twenty-five percent (125%) of the substitute
Allocated Loan Amount, (2) insure Lender's valid first lien on the Substitute
Property, free and clear of all exceptions from coverage other than encumbrances
acceptable to Lender in its sole discretion and standard exceptions and
exclusions from coverage (as modified by the terms of any endorsements), (3)

in the jurisdiction in which the Property is located, as a prudent institutional
lender would require, including, without limitation, a "first loss" endorsement

and acceptable to the Rating Agencies, and prepared in accordance with the 1999
Minimum Standard Detail Requirements for ALTA/ACSM Land Title Surveys. Such
survey shall reflect the same legal description contained in the title insurance
policy relating to such Substitute Property and shall include, among other

remediation as aforesaid shall be an Event of Default; (ii) the cost to
remediate such condition(s) shall be established in the Phase I add/or Phase II

all of Lender's standard requirements or the establishment of a reserve or
escrow in an amount equal to 150% of the cost to cover the remediation, or
delivery of environmental insurance (e.g. secured creditor environmental
insurance policy). In all respects, to the extent any environmental condition
