                                                                  EXECUTION COPY

         ADVISORY AGREEMENT (this "AGREEMENT"), dated as of February 12, 2004,
between PLY GEM INDUSTRIES, INC., a Delaware corporation (the "COMPANY") and
CXCIC LLC, a Delaware limited liability company ("CIC").

         WHEREAS, pursuant to a Stock Purchase Agreement, dated as of December
19, 2003 (the "STOCK PURCHASE AGREEMENT"), among Ply Gem Investment Holdings,
Inc., f/k/a CI Investment Holdings, Inc., (the "PARENT"), Nortek, Inc. and WDS
LLC (together with Nortek, Inc., the "SELLERS"), the Sellers have agreed to
sell, upon the terms and subject to the conditions set forth therein, all of the
outstanding shares of stock of the Company to the Parent (the "ACQUISITION");

         WHEREAS, simultaneously with the execution and delivery of this
Agreement, the Parent, through its wholly owned subsidiary, Ply Gem Holdings,
Inc., is consummating the Acquisition;

         WHEREAS, the Company desires for CIC to provide certain ongoing
advisory and management services to the Company, and CIC is willing to provide
such services subject to the terms and conditions contained herein; and

         WHEREAS, all capitalized terms used in this Agreement but not otherwise
defined herein shall have the meaning ascribed to them in the Stock Purchase
Agreement.

         NOW, THEREFORE, for good and valuable consideration, the receipt of
which is hereby acknowledged, the parties hereto agree as follows:

         SECTION 1.        SERVICES. During the term of this Agreement, CIC
shall provide such acquisition and financial advisory services to the Company
and its subsidiaries as the Board of Directors of the Company shall reasonably
request, including without limitation: general executive and management
services; assistance with the identification, support, negotiation and analysis
of acquisitions and dispositions; assistance with the support, negotiation and
analysis of financial alternatives; and human resource functions.

         SECTION 2.        COMPENSATION.

                  (a)      In consideration of the services to be provided in
accordance with Section 1, but subject to Sections 2(d) and 2(e), the Company
shall pay to CIC, for each fiscal year of the Company, an advisory fee (the
"ANNUAL FEE") equal to 2% of the Company's EBITDA (as defined below) for such
fiscal year. The Annual Fee shall be pro rated for partial years. The Annual Fee
for each fiscal year shall be paid in 12 installments, payable on or before the
10th day of each month (other than the first month) of such fiscal year and the
first month of the next fiscal year, in an amount equal to 2% of the Company's
EBITDA for the previous month. Notwithstanding the foregoing, at the election of
either CIC or the Company, the Annual Fee for such fiscal



                                                                               2


year may be paid in one installment in an amount equal to 99% of the estimated
Annual Fee for such fiscal year (the "ESTIMATED DISCOUNTED ANNUAL FEE"), payable
at any time on or after the Closing, in the case of the Annual Fee for fiscal
year 2004, and on or before the first day of the last month of the Company's
preceding fiscal year, in the case of the Annual Fee for each fiscal year after
fiscal year 2004; PROVIDED, HOWEVER, that if it is determined after the
calculation of the Company's EBITDA for such fiscal year that the amount of such
payment is less than or greater than 99% of the actual Annual Fee for such
fiscal year (the "ACTUAL DISCOUNTED ANNUAL FEE"), then (i) if the Actual
Discounted Annual Fee is greater than the Estimated Discounted Annual Fee, the
Company shall pay to CIC an amount equal to such difference, and (ii) if the
Estimated Discounted Annual Fee is greater than the Actual Discounted Annual
Fee, CIC shall return to the Company an amount equal to such difference, in each
case, within 10 business days of such determination.

                  (b)      Upon the acquisition by the Company of any business
or entity, or similar transactions with respect to which CIC provides services,
the Company shall pay to CIC a transaction fee equal to 2% of the purchase or
sale price, as applicable. Upon the divestiture by the Company of any business
or entity, or similar transactions with respect to which CIC provides services,
the Company shall pay to CIC a transaction fee equal to 1% of the purchase or
sale price, as applicable.

                  (c)      Upon the completion of a merger, consolidation or
other business combination of the Company with and into a third party, or a sale
of all or substantially all of the stock of the Company or any of its direct or
indirect parent companies to a third party, or a sale of all or substantially
all of the assets of the Company and its subsidiaries on a consolidated basis,
the Company shall pay to CIC a transaction fee equal to 1% of the sale price.

                  (d)      CIC shall not be entitled to the Annual Fee with
respect to the first fiscal year of the Initial Term unless (i) the Company's
debt-to-EBITDA ratio for the last twelve months then ended is less than 5.20:1
or (ii) the Company's EBITDA for the last twelve months then ended is at least
$85.5 million; PROVIDED, HOWEVER, that if it is determined that as of December
31, 2005 (i) the Company's debt-to-EBITDA ratio for the last twelve months then
ended is less than 5.20:1 or (ii) the Company's EBITDA for the last twelve
months then ended is at least $85.5 million, any unpaid installment of the
Annual Fee with respect to the first fiscal year of the Initial Term shall be
paid within 10 business days of such determination.

                  (e)      The Annual Fee payable in any fiscal year shall not
exceed the amounts permitted under the Credit Agreement, dated as of the date
hereof, among the Company, the guarantors party thereto, the lenders party

occurred and is continuing under either the Credit Agreement or the Indenture
and the Estimated Discounted Annual Fee has been paid for the fiscal year in
which such Event of Default has occurred, CIC shall promptly return to the
Company an amount equal to the product of (x) the amount of such Estimated
Discounted Annual Fee and (y) a fraction, the numerator of which is the number
of months remaining in such fiscal year (including the month in which such Event
of Default has occurred) and the denominator of which is 12. Notwithstanding

fiscal year upon which the full amount of the Annual Fee payable with respect to
such fiscal year shall be permitted to be paid, such full amount shall be paid,
and upon the first day upon which any partial amount of the Annual Fee that
would have been payable with respect to any prior fiscal year except for the

Company shall pay to CIC, concurrently with such termination, an amount equal to

on the Company's cost of funds to borrow amounts under the revolving credit
facility under the Credit Agreement.

respective partners, members, officers, directors, stockholders, Affiliates,
agents or employees (each, an "INDEMNIFIED PARTY") shall have any liability to
the Company for any services provided pursuant to this Agreement, except as may

Indemnified Party from and against all losses, liabilities, damages,
deficiencies, demands, claims, actions, judgments or causes of action,
assessments, costs or expenses (including, without limitation, interest,
penalties and reasonable fees, expenses and disbursements of attorneys, experts,
personnel and consultants reasonably incurred by such Indemnified Party in any
action or proceeding between the Company and such Indemnified Party or between
such Indemnified Party and any third party, or otherwise) based upon, arising
out of, or otherwise in respect of, this Agreement or any Indemnified Party's
equity interest (whether direct or indirect) in the Company. To the extent that
the foregoing indemnification is not permitted by law, each of the Indemnified
Parties and the Company shall be subject and entitled to contribution based upon
the relative benefits (not to exceed in any event the amount of fees paid to CIC
