            5. Representations and Warranties of the Stockholder. The
Stockholder represents and warrants as follows:

            (a) Binding Agreement. The Stockholder has the capacity to execute
and deliver this Agreement and to consummate the transactions contemplated
hereby. The Stockholder has duly and validly executed and delivered this
Agreement and this Agreement constitutes a legal, valid and binding obligation
of the Stockholder, enforceable against the Stockholder in accordance with its
terms, except as such enforceability may be limited by applicable bankruptcy,
insolvency, reorganization or other similar laws affecting creditors' rights
generally and by general equitable principles (regardless of whether
enforceability is considered in a proceeding in equity or at law).

            (b) Ownership of Shares and Options. The Stockholder is the record
and "beneficial owner" (as defined in Rule 13d-3 under the Securities Exchange
Act of 1934, as amended, which meaning will apply for all purposes of this
Agreement) of the number of Shares set forth in the recitals hereto and is the
owner of the number of Exchange Options set forth in the recitals hereto, in
each case free and clear of any security interests, liens, charges,
encumbrances, equities, claims, options or limitations of whatever nature and
free of any other limitation or restriction (including any restriction on the
right to vote, sell or otherwise dispose of the Shares or Exchange Options).
Except as provided for in the Recapitalization Agreement and the Transactions,
there are no outstanding options or other rights to acquire from the
Stockholder, or obligations of the Stockholder to sell or to dispose of, any
Shares or Exchange Options. As of the date of this Agreement, the number of
Shares and Options set forth in the recitals hereto represent all of the
shares of capital stock of the Company beneficially owned by the Stockholder,
other than Benefit Plan Shares.

            (c) No Conflict. Neither the execution and delivery of this
Agreement, the consummation of the transactions contemplated hereby, nor the
performance of the Stockholder's obligations hereunder will (a) result in a
violation or breach of, or constitute (with or without due notice or lapse of
time or both) a default (or give rise to any right of termination,
cancellation, or acceleration) under any contract, agreement, instrument,
commitment, arrangement or understanding, or result in the creation of a
security interest, lien, charge, encumbrance, equity or claim with respect to
the Stockholder's Shares or Exchange Options, or (b) require any material
consent, authorization or approval of any person other than a governmental
entity, or (c) violate or conflict with any writ, injunction or decree
applicable to the Stockholder or the Stockholder's Shares, Exchange Options,
Nortek Holdings Preference Stock to be received by Stockholder or Class A
Common Stock to be received by Stockholder upon conversion thereof.

            (d) Federal Securities Laws Matters. The Stockholder acknowledges
receipt of advice from the Company that (i) the shares of Nortek Holdings
Preference Stock (and the Class A Common Stock issuable upon conversion
thereof) have not been registered under the Securities Act of 1933 (the
"Securities Act"), (ii) the shares of Nortek Holdings Preference Stock must be
held indefinitely and the Stockholder must continue to bear the economic risk
of the investment in the shares of Nortek Holdings Preference Stock (and the
Class A Common Stock issuable upon conversion thereof), unless such shares of
Nortek Holdings Preference Stock (and the Class A Common Stock issuable upon
conversion thereof) are subsequently registered under the Securities Act, or
an exemption from such registration is available, (iii) it is not anticipated
that there will be any public market for the shares of Nortek Holdings
Preference Stock (and the Class A Common Stock issuable upon conversion
thereof) in the foreseeable future, (iv) Rule 144 promulgated under the
Securities Act will not initially be available with respect to the sales of
the shares of Nortek Holdings Preference Stock (and the Class A Common Stock
issuable upon conversion thereof), and neither Nortek nor Nortek Holdings has
made any covenant to make such rule available and such rule is not anticipated
to be available in the foreseeable future, (v) when and if the shares of
Nortek Holdings Preference Stock (and the Class A Common Stock issuable upon
conversion thereof) may be disposed of without registration in reliance upon
Rule 144, such disposition can be made only in limited amounts and in
accordance with the terms and conditions of such rule, (vi) if the exemption
afforded by Rule 144 is not available, public sale of the shares of Nortek
Holdings Preference Stock (and the Class A Common Stock issuable upon
conversion thereof) without registration will require the availability of an
exemption under the Securities Act, and (vii) a notation may be made in the
appropriate records of the Company indicating that the Nortek Holdings
Preference Stock (and the Class A Common Stock issuable upon conversion
thereof) is subject to restrictions on transfer and, if the Company should in
the future engage the services of a stock transfer agent, appropriate
stop-transfer restrictions will be issued to such transfer agent with respect
to the shares of Nortek Holdings Preference Stock (and the Class A Common
Stock issuable upon conversion thereof).

            (e) Stockholder Status. Either (i) the Stockholder is an
"accredited investor" as such term is defined in Rule 501(a) promulgated under
the Securities Act or (ii) (A) the Stockholder's financial situation is such
that the Stockholder can afford to bear the economic risk of holding the
shares of Nortek Holdings Preference Stock (and the Class A Common Stock
issuable upon conversion thereof) for an indefinite period of time, (B) the
Stockholder can afford to suffer complete loss of his investment in the shares
of Nortek Holdings Preference Stock (and the Class A Common Stock issuable
upon conversion thereof), (C) the Stockholder's knowledge and experience in
financial and business matters are such that the Stockholder is capable of
evaluating the merits and risks of the Stockholder's investment in the shares
of Nortek Holdings Preference Stock (and the Class A Common Stock issuable
upon conversion thereof), and (D) the Stockholder understands and has taken
cognizance of all the risk factors related to the purchase of the shares of
Nortek Holdings Preference Stock (and the Class A Common Stock issuable upon
conversion thereof).

intended or shall be construed to give any person other than the parties to
this Agreement and their respective successors or permitted assigns any legal
or equitable right, remedy or claim under or in respect of any agreement or
any provision contained herein. No party shall have liability for any breach

intentional breach thereof.

altered or supplemented except upon the execution and delivery of a written

modification, amendment, alteration or supplement shall not require the
consent of the Company; provided, however, that any modification, amendment,
alteration or supplement to the obligations of the Company with respect to the
Share Exchange or Option Exchange, to the extent it imposes obligations on the
Company that are applicable prior to the consummation of the Reclassification
or in the event the Reclassification is not consummated or to the extent it
would cause a condition to the closing of the transactions contemplated by the
Recapitalization Agreement not to be satisfied or give rise to a right of

enforced, the parties hereto shall negotiate in good faith to modify this
Agreement so as to effect the original intent of the parties as closely as

terminate this Agreement. Termination shall not relieve any party from
liability for any intentional breach of its obligations hereunder committed
prior to such termination.
