                           RECEIVABLES SALE AGREEMENT

                  THIS RECEIVABLES SALE AGREEMENT, dated as of June 27, 2003, is
by and among Armstrong Air Conditioning Inc., an Ohio corporation ("Armstrong"),
Lennox Hearth Products Inc., a California corporation ("Hearth") (each of
Armstrong and Hearth and each other Subsidiary of Lennox International which
hereafter enters into a Joinder Agreement, an "Originator" and collectively, the
"Originators"), and LPAC Corp. II, a Delaware corporation ("Buyer"). Unless
defined elsewhere herein, capitalized terms used in this Agreement shall have
the meanings assigned to such terms in Exhibit I.

                             PRELIMINARY STATEMENTS

                  Each Originator now owns, and from time to time hereafter will
own, Receivables. Each Originator wishes to sell and assign to Buyer, and Buyer
wishes to purchase from each Originator, all of such Originator's right, title
and interest in and to such Receivables, together with the Related Security and
Collections with respect thereto.

                  Each Originator and Buyer intend the transactions contemplated
hereby to be true sales of the Receivables from such Originator to Buyer,
providing Buyer with the full benefits of ownership of the Receivables, and none
of the Originators or Buyer intends these transactions to be, or for any purpose
to be characterized as, loans from Buyer to an Originator.

                  Following each purchase of Receivables from the Originators,
Buyer will sell undivided interests therein and in the associated Related
Security and Collections pursuant to that certain Receivables Purchase Agreement
dated as of June 27, 2003 (as the same may from time to time hereafter be
amended, supplemented, restated or otherwise modified, the "Purchase Agreement")
among Buyer, Lennox Industries Inc., as Servicer, Jupiter Securitization
Corporation ("Jupiter"), the financial institutions from time to time party
thereto as "Financial Institutions" and Bank One, NA (Main Office Chicago) or
any successor agent appointed pursuant to the terms of the Purchase Agreement,
as agent for Jupiter and such Financial Institutions (in such capacity, the
"Agent").

                                   ARTICLE I
                                AMOUNTS AND TERMS

                  Section 1.1 Purchases of Receivables.

                  (a)      In consideration for the Purchase Price and upon the
terms and subject to the conditions set forth herein, (i) effective on its
Closing Date, each Originator does hereby sell, assign, transfer, set-over and
otherwise convey to Buyer, without recourse (except to the extent expressly
provided herein), and Buyer does hereby purchase from each Originator, all of
such Originator's right, title and interest in and to all Receivables originated
by such Originator and existing as of the close of business on the Business Day
immediately prior to its Closing Date, together, in each case, with all Related
Security relating thereto and all Collections thereof and



(ii) from and after its Closing Date, each Originator hereby agrees to sell,
assign, transfer, set-over and otherwise convey to Buyer, without recourse
(except to the extent expressly provided herein), and Buyer hereby agrees to
purchase from each Originator, all of such Originator's right, title and
interest in and to all Receivables originated by such Originator from and after
its Closing Date, together, in each case, with all Related Security relating
thereto and all Collections thereof. In accordance with the preceding sentence,
Buyer shall acquire all of each Originator's right, title and interest in and to
all Receivables originated by such Originator existing as of the close of
business on the Business Day immediately prior to its Closing Date and
thereafter arising through and including its Termination Date, together with all
Related Security relating thereto and all Collections thereof, and Buyer shall
be obligated to pay the Purchase Price therefor in accordance with Section 1.2.
In connection with the payment of the Purchase Price for any Receivables
purchased hereunder, Buyer may request that the applicable Originator deliver,
and such Originator shall deliver, such approvals, opinions, information,
reports or documents as Buyer may reasonably request.

                  (b)      It is the intention of the parties hereto that each
Purchase of Receivables made hereunder shall constitute a sale of "accounts" (as
such term is used in Article 9 of the UCC), which sale is absolute and
irrevocable and provides Buyer with the full benefits of ownership of the
Receivables. Except for the Purchase Price Credits owed pursuant to Section 1.3,
each sale of Receivables hereunder is made without recourse to the Originators;
provided, however, that (i) each Originator shall be liable to Buyer for all
representations, warranties and covenants made by such Originator pursuant to
the terms of the Transaction Documents to which such Originator is a party, and
(ii) such sale does not constitute and is not intended to result in an
assumption by Buyer or any assignee thereof of any obligation of such Originator
or any other Person arising in connection with the Receivables originated by
such Originator, the related Contracts and/or other Related Security or any
other obligations of such Originator. In view of the intention of the parties
hereto that the Purchases of Receivables made hereunder shall constitute a sale
of such Receivables rather than loans secured thereby, each Originator agrees
that it will, on or prior to its Closing Date and in accordance with Section
4.1(e)(ii), mark its master data processing records relating to the Receivables
originated by it with a legend acceptable to Buyer and to the Agent (as Buyer's
assignee), evidencing that Buyer has purchased such Receivables as provided in
this Agreement and to note in its financial statements that its Receivables have
been sold to Buyer. Upon the request of Buyer or the Agent (as Buyer's
assignee), each Originator will execute and file such financing or continuation
statements, or amendments thereto or assignments thereof, and such other
instruments or notices, as may be necessary or appropriate to perfect and
maintain the perfection of Buyer's ownership interest in the Receivables and the
Related Security and Collections with respect thereto, or as Buyer or the Agent
(as Buyer's assignee) may reasonably request.

                  Section 1.2 Payment for the Purchases.

                  (a)      The Purchase Price for the Purchase of Receivables of
each Originator that are in existence on the close of business on the Business
Day immediately preceding its Closing Date (the "Initial Cutoff Date") shall be
payable in full by Buyer to such Originator on its Closing Date, and shall be
paid to such Originator in the following manner:

                                       2



                           (i)      by delivery of immediately available funds,
         to the extent of funds made available to Buyer in connection with its
         subsequent sale of an interest in such Receivables to the Purchasers
         under the Purchase Agreement or other cash on hand;

                           (ii)     by delivery of the proceeds of a
         subordinated revolving loan from such Originator to Buyer (a
         "Subordinated Loan") in an amount not to exceed the least of (A) the
         remaining unpaid portion of such Purchase Price and (B) the maximum
         Subordinated Loan that could be borrowed without rendering Buyer's Net
         Worth less than the Required Capital Amount; and

                           (iii)    by accepting such Receivables as a
         contribution to Buyer's capital in exchange for shares of Series A
         Preferred Stock in accordance with the terms of the Stock Purchase
         Agreement.

Each Receivable coming into existence after the Initial Cutoff Date shall be
sold or contributed to the Buyer on the Business Day immediately following the
day such Receivable was originated and the Purchase Price for such Receivable
shall be due and owing in full by Buyer to the Originator of such Receivable or
its designee on such Business Day (except that Buyer may, with respect to any
such Purchase Price, offset against such Purchase Price any amounts owed by such
Originator to Buyer hereunder and which have become due but remain unpaid) and
shall be paid to such Originator in the manner provided in the following
paragraphs (b), (c) and (d).

                  (b)      With respect to any Receivables sold or contributed
hereunder after the Initial Cutoff Date, on the first Business Day after such
Receivable is originated, such Receivable shall be transferred to Buyer and on
such date of Purchase, Buyer shall pay the Purchase Price therefor to the
applicable Originator in the following manner:

                           (i)      first, by delivery of immediately available
         funds, to the extent of funds available to Buyer from its subsequent
         sale of an interest in the Receivables to the Agent for the benefit of
         the Purchasers under the Purchase Agreement or other cash on hand;

                           (ii)     second, by delivery of the proceeds of a
         Subordinated Loan, provided that the making of any such Subordinated
         Loan shall be subject to the provisions set forth in Section
         1.2(a)(ii); and

                           (iii)    third, by accepting such Receivables as a
         contribution to Buyer's capital in exchange for shares of Series A
         Preferred Stock in accordance with the terms of the Stock Purchase
         Agreement; PROVIDED that no such capital contribution shall be made
         from and after the date on which such Originator notifies Buyer in
         writing that it has designated a date as such Originator's Termination
         Date.

Subject to the limitations set forth in Section 1.2(a)(ii), each Originator
irrevocably agrees to advance each Subordinated Loan requested by Buyer on or
prior to such Originator's Termination Date. The Subordinated Loans shall be
evidenced by, and shall be payable in accordance with the terms and provisions
of such Originator's Subordinated Note and shall be

                                       3



payable solely from funds which Buyer is not required under the Purchase
Agreement to set aside for the benefit of, or otherwise pay over to, the Agent
or the Purchasers. Such Originator is hereby authorized by Buyer to endorse on
the schedule attached to its Subordinated Note an appropriate notation
evidencing the date and amount of each advance thereunder, as well as the date
of each payment with respect thereto, provided that the failure to make such
notation shall not affect any obligation of Buyer thereunder.

                  (c)      From and after its Termination Date, no Originator
shall be obligated to (but may, at its option) sell Receivables to Buyer unless
such Originator reasonably determines that the Purchase Price therefor will be
satisfied with funds available to Buyer from sales of interests in the
Receivables pursuant to the Purchase Agreement, Collections, proceeds of
Subordinated Loans, other cash on hand or otherwise.

                  (d)      Although the Purchase Price for each Receivable
coming into existence after the Initial Cutoff Date shall be paid in full by
Buyer to the applicable Originator on the date such Receivable is purchased, a
precise reconciliation of the Purchase Price between Buyer and such Originator
shall be effected on a monthly basis on Settlement Dates with respect to all
Receivables sold during the same Calculation Period most recently ended prior to
such Settlement Date and based on the information contained in the Monthly
Report delivered by the Servicer pursuant to Article VIII of the Purchase
Agreement for such Calculation Period. Although such reconciliation shall be
effected on Settlement Dates, increases or decreases in the amount owing under
the applicable Subordinated Note made pursuant to Section 1.2(b) and any
contribution of capital by the applicable Originator to Buyer made pursuant to
Section 1.2(b) shall be deemed to have occurred and shall be effective as of the
date that the Purchase Price is paid. On each Settlement Date, each Originator
shall determine the net increase or the net reduction in the outstanding
principal amount of its Subordinated Note occurring during the immediately
preceding Calculation Period and shall account for such net increase or net
reduction in its books and records. Each Originator hereby agrees that within
three (3) Business Days after Buyer so requests, such Originator will provide
Buyer with a current report of daily sales giving rise to Receivables purchased
hereunder and a current daily report of Collections received.

                  (e)      Each contribution of a Receivable by an Originator to
Buyer shall be deemed to be a Purchase of such Receivable by the Buyer for all
purposes of this Agreement. Buyer hereby acknowledges that no Originator shall
have any obligations to make further capital contributions to Buyer, in respect
of Originator's equity interest in the Buyer or otherwise, in order to provide
funds to pay the Purchase Price to such Originator under this Agreement or for
any other reason.

                  Section 1.3 Purchase Price Credit Adjustments.

                  (a)      If on any day the Outstanding Balance of a Receivable
is:

                           (i)      reduced as a result of any defective or
         rejected goods or services, any volume incentive discount, promotional
         or advertising credits, any other discount or any adjustment or
         otherwise by the applicable Originator (other than cash Collections on

                                       4



         account of such Receivable and other than reductions resulting from
         such Receivable being written off the applicable Originator's books as
         uncollectible on account of the insolvency, bankruptcy or lack of
         creditworthiness of the related Obligor),

                           (ii)     reduced or canceled as a result of a setoff
         in respect of any claim by any Person (whether such claim arises out of
         the same or a related transaction or an unrelated transaction), or

                  (b)      if any of the representations and warranties set
forth in Article II were not true with respect to any Receivable on the date of
its Purchase hereunder,

then, in such event, Buyer shall be entitled to a credit (each, a "Purchase
Price Credit") against the Purchase Price otherwise payable hereunder in an
amount equal to the amount of such reduction or cancellation in the case of
clause (a) or the Outstanding Balance of such Receivable in the case of clause
(b). If such Purchase Price Credit exceeds the Purchase Price for the
Receivables sold by such Originator on such day, then such Originator shall pay
the remaining amount of such Purchase Price Credit in cash within five (5)
Business Days thereafter, provided that if the Termination Date of such
Originator has not occurred, such Originator shall be allowed to deduct the
remaining amount of such Purchase Price Credit from any indebtedness owed to it
under its Subordinated Note to the extent permitted thereunder.

                  Section 1.4 Payments and Computations, Etc. All amounts to be
paid or deposited by Buyer hereunder shall be paid or deposited in accordance
with the terms hereof on the day when due in immediately available funds to the
account of the applicable Originator designated from time to time by such
Originator or as otherwise directed by such Originator. In the event that any
payment owed by any Person hereunder becomes due on a day that is not a Business
Day, then such payment shall be made on the next succeeding Business Day. If any
Person fails to pay any amount hereunder when due, such Person agrees to pay, on
demand, the Default Fee in respect thereof until paid in full; provided,
however, that such Default Fee shall not at any time exceed the maximum rate
permitted by applicable law. All computations of interest payable hereunder
shall be made on the basis of a year of 360 days for the actual number of days
(including the first but excluding the last day) elapsed.

                  Section 1.5 Transfer of Records.

                  (a)      In connection with each Purchase of Receivables
hereunder, each Originator hereby sells, transfers, assigns and otherwise
conveys to Buyer all of such Originator's right and title to and interest in the
Records relating to all Receivables sold hereunder, without the need for any
further documentation in connection with such Purchase. In connection with such
transfer, each Originator hereby grants to each of Buyer, the Agent and the
Servicer an irrevocable, non-exclusive license to use, without royalty or
payment of any kind, all software used by such Originator to account for the
Receivables, to the extent necessary to administer the Receivables, whether such
software is owned by such Originator or is owned by others and used by such
Originator under license agreements with respect thereto, provided that should
the consent of any licensor of such software to such grant of the license
described herein be required, such Originator hereby agrees that upon the
request of Buyer (or the Agent as Buyer's assignee), such Originator will use
its reasonable efforts to obtain the consent of such

                                       5



third-party licensor. The license granted hereby shall be irrevocable, and shall
terminate on the date this Agreement terminates in accordance with its terms.

                  (b)      Each Originator (i) shall take such action requested
by Buyer and/or the Agent (as Buyer's assignee), from time to time hereafter,
that may be necessary or appropriate to ensure that Buyer and its assigns under
the Purchase Agreement have an enforceable ownership interest in the Records
relating to the Receivables purchased from such Originator hereunder, and (ii)
shall use its reasonable efforts to ensure that Buyer, the Agent and the
Servicer each has an enforceable right (whether by license or sublicense or
otherwise) to use all of the computer software used to account for the
Receivables and/or to recreate such Records.

                  Section 1.6 Characterization. (a) If, notwithstanding the
intention of the parties expressed in Section 1.1(b), any sale or contribution
by an Originator to Buyer of Receivables hereunder shall be characterized as a
secured loan and not a sale or such sale shall for any reason be ineffective or
unenforceable, then this Agreement shall be deemed to constitute a security
agreement under the UCC and other applicable law. For this purpose and without
being in derogation of the parties' intention that the sale of Receivables
hereunder shall constitute a true sale thereof, each Originator hereby grants to
Buyer a valid and perfected security interest in all of such Originator's right,
title and interest, now owned or hereafter acquired, in, to and under all
Receivables now existing and hereafter arising, and in all Collections, Related
Security with respect thereto, each Lock-Box and Collection Account, all other
rights and payments relating to the Receivables and all proceeds of the
foregoing to secure the prompt and complete payment of a loan deemed to have
been made in an amount equal to the Purchase Price of the Receivables originated
by such Originator together with all other obligations of such Originator
hereunder, which security interest shall be prior to all other Adverse Claims
thereto. Buyer and its assigns shall have, in addition to the rights and
remedies which they may have under this Agreement, all other rights and remedies
provided to a secured creditor under the UCC and other applicable law, which
rights and remedies shall be cumulative. Each Originator hereby authorizes the
Buyer (or its assigns), within the meaning of Section 9-509 of any applicable
enactment of the UCC, as secured party, to file, without the signature of the
debtor, the UCC financing statements contemplated hereby.

                  (b)      Each Originator acknowledges that Buyer, pursuant to
the Purchase Agreement, shall assign to the Agent, for the benefit of the Agent
and the Purchasers thereunder, all of its rights, remedies, powers and
privileges under this Agreement and that the Agent may further assign such
rights, remedies, powers and privileges to the extent permitted by the Purchase
Agreement. Each Originator agrees that the Agent, as the assignee of the Buyer,
shall, subject to the terms of the Purchase Agreement, have the right to enforce
this Agreement and to exercise directly all of Buyer's rights and remedies under
this Agreement (including, without limitation, the right to give or withhold any
consents or approvals of Buyer to be given or withheld hereunder, and, in any
case without regard to whether specific reference is made to Buyer's assigns in
the provisions of this Agreement which set forth such rights and remedies) and
each Originator agrees to cooperate fully with the Agent and the Purchasers in
the exercise of such rights and remedies. Each Originator further agrees to give
to the Agent copies of all notices it is required to give to Buyer hereunder.

                                       6



                                   ARTICLE II
                         REPRESENTATIONS AND WARRANTIES

                  Section 2.1 Representations and Warranties of Originators.
Each Originator hereby represents and warrants to Buyer on the date hereof and
on the date of each Purchase hereunder that:

                  (a)      Corporate Existence and Power. Such Originator is a
corporation duly organized, validly existing and in good standing under the laws
of its state of incorporation. Such Originator is duly qualified to do business
and is in good standing as a foreign corporation, and has and holds all
corporate power and all governmental licenses, authorizations, consents and
approvals required to carry on its business in each jurisdiction in which its
business is conducted, except to the extent that the failure to qualify or to
hold such governmental licenses, authorizations, consents and approvals could

                  (f)      Binding Effect. This Agreement and each other
Transaction Document to which such Originator is a party constitute the legal,
valid and binding obligations of such Originator enforceable against such
Originator in accordance with their respective terms, except as such enforcement

similar laws relating to or limiting creditors' rights generally and by general
principles of equity (regardless of whether enforcement is sought in a
proceeding in equity or at law).

                  (g)      Accuracy of Information. All information heretofore

misleading.

                  (h)      Use of Proceeds. No proceeds of the Purchases

other similar instruments or documents necessary under the UCC (or any

ownership interest in each such Receivable, its Collections and the Related
Security. Armstrong hereby represents and warrants that immediately prior to

sold by it thereunder, free and clear of any Adverse Claim, except as created by
the Transaction Documents and there have been duly filed all financing

existing or hereafter arising, together with the Related Security and
Collections with respect thereto, free and clear of any Adverse Claim, except as
created by the Transaction Documents. There have been duly filed all financing
statements or other similar instruments or documents necessary under the UCC (or
any comparable law) of all appropriate jurisdictions to perfect Buyer's security
interest in the Receivables, the Related Security and the Collections.

of its Records are located at the address(es) listed on Exhibit II or such other
locations of which Buyer has been notified in accordance with Section 4.2(a) in

forth on Exhibit II.

owns 100% of the issued and outstanding capital stock of Buyer, each Originator
directly owns 5% of the issued and outstanding common stock of Buyer, Heatcraft
Technologies Inc. directly owns 85% of the issued and outstanding common stock
of Buyer, and collectively the Originators directly own all of the issued and
outstanding preferred stock of Buyer, in each case free and clear of any Adverse
Claim. Such capital stock is validly issued, fully paid and nonassessable, and
there are no options, warrants or other rights to acquire equity securities of
Buyer.

                  (p)      Not a Holding Company or an Investment Company. Such
Originator is not a "holding company" or a "subsidiary holding company" of a
"holding company" within the meaning of the Public Utility Holding Company Act
of 1935, as amended, or any successor statute. Such Originator is not an
"investment company" within the meaning of the Investment Company Act of 1940,
as amended, or any successor statute.

                  (q)      Compliance with Law. Such Originator has complied in
all respects with all applicable laws, rules, regulations, orders, writs,
judgments, injunctions, decrees or awards to which it may be subject, except
where the failure to so comply could not reasonably be expected to have a
Material Adverse Effect. Each Receivable originated by such Originator, together
with the Contract related thereto, does not contravene any laws, rules or
regulations applicable thereto (including, without limitation, laws, rules and
regulations relating to truth in lending, fair credit billing, fair credit
reporting, equal credit opportunity, fair debt collection practices and
privacy), and no part of such Contract is in violation of any such law, rule or
regulation, except where such contravention or violation could not reasonably be

and Collection Policy, other than as permitted under Section 4.2 and in
compliance with the notification requirements of Section 4.1(a)(vii).

                  (s)      Payments to Originator and LPAC Corp. With respect to
each Receivable originated by such Originator and transferred to Buyer
hereunder, the Purchase Price received by such Originator constitutes reasonably
equivalent value in consideration therefor and such transfer was not made for or
on account of an antecedent debt. No transfer by such Originator of any
Receivable hereunder is or may be voidable under any section of the Bankruptcy
Reform Act of 1978 (11 U.S.C. Sections 101 et seq.), as amended. With respect
to each Receivable transferred to Armstrong under the Sale and Assignment, the
purchase price paid by Armstrong constitutes reasonably equivalent value in
consideration therefor and such transfer was not made for or on account of an
antecedent debt. No transfer by LPAC Corp. of any Receivable under the Sale and
Assignment is or may be voidable under any section of the Bankruptcy Reform Act
of 1978 (11 U.S.C. Sections 101 et seq.), as amended.

                  (t)      Enforceability of Contracts. Each Contract with
respect to each Receivable originated by such Originator is effective to create,
and has created, a legal, valid and binding obligation of the related Obligor to
pay the Outstanding Balance of the Receivable created thereunder and any accrued
interest thereon, enforceable against the Obligor in accordance with its terms,
except as such enforcement may be limited by applicable bankruptcy, insolvency,
reorganization or other similar laws relating to or limiting creditors' rights
generally and by general principles of equity (regardless of whether enforcement
is sought in a proceeding in equity or at law).

                  (u)      Eligible Receivables. Each Receivable included in the
Net Receivables Balance as an Eligible Receivable on the date of its purchase
hereunder was an Eligible Receivable on such date.

                  (v)      Accounting. The manner in which such Originator
accounts for the transactions contemplated by this Agreement does not jeopardize
the characterization of the transactions contemplated herein as being true
sales.

that the Agent and the Purchasers are entering into the transactions
contemplated by the Purchase Agreement in reliance upon Buyer's identity as a
legal entity that is separate from any Lennox Entity. Therefore, from and after
the date of execution and delivery of this Agreement, such Originator will take
all reasonable steps including, without limitation, all steps that Buyer or any
assignee of Buyer may from time to time reasonably request to maintain Buyer's
identity as a separate legal entity and to make it manifest to third parties
that Buyer is an entity with assets and liabilities distinct from those of such
Originator and not just a division of such Originator. Without

                                       13



limiting the generality of the foregoing and in addition to the other covenants
set forth herein, such Originator (i) will not hold itself out to third parties
as liable for the debts of Buyer nor purport to own the Receivables and other
assets acquired by Buyer, (ii) will take all other actions necessary on its part
to ensure that Buyer is at all times in compliance with the covenants set forth
in Section 7.1(i) of the Purchase Agreement and (iii) will cause all tax
liabilities arising in connection with the transactions contemplated herein or
otherwise to be allocated between such Originator and Buyer on an arm's-length
basis and in a manner consistent with the procedures set forth in U.S. Treasury
Regulations Sections 1.1502-33(d) and 1.1552-1.

                  (i)      Collections. Such Originator will cause (1) all
Collections to be remitted by the Obligors directly to either a Lock-Box or a
Collection Account, (2) all proceeds from all Lock-Boxes to be directly
deposited by a Collection Bank into a Collection Account and (3) each Lock-Box
and Collection Account to be subject at all times to a Collection Account
Agreement that is in full force and effect; provided that Hearth shall have 30
days after the date hereof to deliver a fully executed Collection Account
Agreement with respect to the Lock-Box and Collection Account into which
Collections of Receivables originated by Hearth are deposited. In the event any
payments relating to Receivables are remitted directly to such Originator or any
Affiliate of such Originator, such Originator will remit (or will cause all such
payments to be remitted) directly to a Collection Bank for deposit into a
Collection Account within two (2) Business Days following receipt thereof and,
at all times prior to such remittance, such Originator will itself hold or, if
applicable, will cause such payments to be held in trust for the exclusive
benefit of Buyer and its assigns. Such Originator will transfer exclusive
ownership, dominion and control of each Lock-Box and Collection Account to
Buyer, and will not grant the right to take dominion and control of any Lock-Box
or Collection Account at a future time or upon the occurrence of a future event
to any Person, except to Buyer (or its assigns) as contemplated by this
Agreement and the Purchase Agreement.

                  (j)      Taxes. Such Originator will file all tax returns and
reports required by law to be filed by it and will promptly pay all taxes and
governmental charges at any time owing except any such taxes which are not yet
delinquent or are being diligently contested in good faith by appropriate
proceedings and for which adequate reserves in accordance with generally
accepted accounting principles shall have been set aside on its books. Such
Originator will pay when due any taxes payable in connection with the
Receivables, exclusive of taxes on or measured by income or gross receipts of
Buyer and its assigns.

                  (k)      Insurance. Such Originator will maintain in effect,
or cause to be maintained in effect, at such Originator's own expense, such
casualty and liability insurance covering the Equipment as such Originator deems
appropriate in its good faith business judgment.

on which this Agreement terminates in accordance with its terms, each Originator
hereby covenants that:

                  (a)      Name Change, Offices and Records. Such Originator
will not (i) make any change to its name (within the meaning of Section 9-507(c)
of any applicable enactment of the UCC), identity, corporate structure or chief
executive office or location of its books and records unless, at least thirty
(30) days prior to the effective date of any such name change,

                                       14



change in corporate structure, or change in location of its chief executive
office or books and records such Originator notifies Buyer (and its assigns)
thereof and delivers to the Agent such financing statements (Forms UCC-1 and
UCC-3) authorized or executed by such Originator (if required under applicable
law) which Buyer (or its assigns) may reasonably request to reflect such name
change, location change, or change in corporate structure, together with such
other documents and instruments that Buyer (or its assigns) may reasonably
request in connection therewith and has taken all other steps to ensure that
Buyer (and its assigns) continues to have a first priority, perfected security
interest in the Receivables originated by such Originator, the Related Security
related thereto and any Collections thereon, or (ii) change its jurisdiction of
organization unless the Buyer (and its assigns) shall have received from such
Originator, prior to such change, (A) those items described in clause (i)
hereof, and (B) if Buyer (or its assigns) shall so request, an opinion of
counsel, in form and substance reasonably satisfactory to such Person, as to
such organization and such Originator's valid existence and good standing and
the perfection and priority of Buyer's and the Agent's security interests in the
Receivables originated by such Originator, the Related Security and Collections.

                  (b)      Change in Payment Instructions to Obligors. Such
Originator will not add or terminate any bank as a Collection Bank, or make any
change in the instructions to Obligors regarding payments to be made to any
Lock-Box or Collection Account, unless Buyer (and its assigns) shall have
received, at least ten (10) days before the proposed effective date therefor,
(i) written notice of such addition, termination or change and (ii) with respect
to the addition of a Collection Bank or a Collection Account or Lock-Box, an
executed Collection Account Agreement with respect to the new Collection Account
or Lock-Box; provided, however, that such Originator may make changes in
instructions to Obligors regarding payments if such new instructions require
such Obligor to make payments to another existing Collection Account or
Lock-Box.

                  (c)      Modifications to Contracts and Credit and Collection
Policy. Such Originator will not make any change to the Credit and Collection
Policy that could adversely affect the collectibility of the Receivables or
decrease the credit quality of any newly created Receivables. Such Originator
will not extend, amend or otherwise modify the terms of any Receivable or any
Contract related thereto other than in accordance with its Credit and Collection
Policy.

                  (d)      Sales, Liens. Such Originator will not sell, assign
(by operation of law or otherwise) or otherwise dispose of, or grant any option
with respect to, or create or suffer to exist any Adverse Claim upon (including,
without limitation, the filing of any financing statement) or with respect to,
any Receivable, Related Security or Collections, or upon or with respect to any
Contract under which any Receivable arises, or any Lock-Box or Collection
Account, or assign any right to receive income with respect thereto (other than,
in each case, the creation of the interests therein in favor of Buyer provided
for herein), and such Originator will defend the right, title and interest of
Buyer and its assigns in, to and under any of the foregoing property, against
all claims of third parties claiming through or under such Originator. Such
Originator shall not create or suffer to exist any mortgage, pledge, security
interest, encumbrance, lien, charge or other similar arrangement on any of its
inventory, the financing or lease of which gives rise to a Receivable.

                                       15



                  (e)      Accounting for Purchases. Such Originator will not,
and will not permit any Affiliate to, account for or treat (whether in financial
statements or otherwise) the transactions contemplated hereby in any manner
other than the sale of the Receivables originated by it and the Related Security
and Collections with respect thereto by such Originator to Buyer or in any other
respect account for or treat the transactions contemplated hereby in any manner
other than as a sale of the Receivables originated by it and the Related
Security and Collections with respect thereto by such Originator to Buyer except
to the extent that such transactions are not recognized on account of
consolidated financial reporting in accordance with generally accepted
accounting principles.

                               TERMINATION EVENTS

                  Section 5.1 Termination Events. The occurrence of any one or
more of the following events shall constitute a Termination Event with respect
to an Originator:

                  (a)      Such Originator shall fail (i) to make any payment or
deposit required hereunder or under any other Transaction Document when due and
such failure shall continue for one (1) Business Day, or (ii) to perform or
observe any term, covenant or agreement hereunder (other than as referred to in
clause (i) of this paragraph (a)) or any other Transaction Document to which it

statement made by such Originator or Performance Guarantor in this Agreement,
any other Transaction Document or in any other document delivered pursuant
hereto or thereto shall prove to have been incorrect in any material respect
when made or deemed made (except that the materiality standard in this
subsection (b) shall not apply to any such representation or warranty which is
qualified by a materiality standard by its terms).

                  (c)      Failure of such Originator or Performance Guarantor
to pay any Indebtedness when due (after the passage of any applicable notice and
grace period) in excess of $10,000,000; or the default (after the passage of any
applicable notice and grace period) by such Originator or Performance Guarantor
in the performance of any term, provision or condition contained in any
agreement under which such Indebtedness was created or is governed, the effect
of which is to cause, or to permit the holder or holders of such Indebtedness to
cause, such Indebtedness to become due prior to its stated maturity; provided
that Bank One has not waived any such default in its capacity as a lender under
such agreement; or any such Indebtedness of such Originator or Performance
Guarantor shall be declared to be due and payable or required to be prepaid
(other than by a regularly scheduled payment) prior to the date of maturity
thereof.

                  (d)      (i) Such Originator or Performance Guarantor shall
generally not pay its debts as such debts become due or shall admit in writing
its inability to pay its debts generally or shall make a general assignment for
the benefit of creditors; or (ii) any proceeding shall be

                                       16

insolvent, or seeking liquidation, winding up, reorganization, arrangement,

covered by insurance or as to which the insurance carrier has denied its
responsibility, and such judgment shall continue unsatisfied and in effect for
thirty (30) consecutive days without a stay of execution.

                  (g)      Performance Guarantor shall fail to perform or
observe any term, covenant or agreement required to be performed by it under the
Performance Guaranty, or the Performance Guaranty shall cease to be effective or
to be the legally valid, binding and enforceable obligation of Performance
Guarantor, or Performance Guarantor shall directly or indirectly contest in any
manner such effectiveness, validity, binding nature or enforceability.

                  Section 5.2 Remedies. Upon the occurrence and during the
continuation of a Termination Event with respect to any Originator, Buyer may
take any of the following actions: (i) declare such Originator's Termination
Date to have occurred, whereupon its Termination Date shall forthwith occur,
without demand, protest or further notice of any kind, all of which are hereby
expressly waived by each Originator; provided, however, that upon the occurrence
of Termination Event described in Section 5.1(d), or of an actual or deemed
entry of an order for relief with respect to any Originator under the Federal
Bankruptcy Code, such Originator's Termination Date shall automatically occur,
without demand, protest or any notice of any kind, all of which are hereby
expressly waived by each Originator and (ii) to the fullest extent permitted by
applicable law, declare that the Default Fee shall accrue with respect to any
amounts then due and owing to Buyer by such Originator. The aforementioned
rights and remedies shall be without limitation and in addition to all other
rights and remedies of Buyer and its assigns available under this Agreement, by

preserved, including, without limitation, all rights and remedies provided under
the UCC, all of which rights shall be cumulative.

                                   ARTICLE VI
                                 INDEMNIFICATION

                  Section 6.1 Indemnities by Originators. Without limiting any
other rights that Buyer may have hereunder or under applicable law, each
Originator hereby agrees to indemnify (and pay upon demand to) Buyer and its
assigns, and their respective assigns, officers, directors, agents and employees
(each an "Indemnified Party") from and against any and all damages,

                                       17



losses, claims, taxes, liabilities, costs, expenses and for all other amounts
payable, including reasonable attorneys' fees (which attorneys may be employees
of Buyer or its assigns) and disbursements (all of the foregoing being
collectively referred to as "Indemnified Amounts") awarded against or incurred
by any of them arising out of or as a result of this Agreement or the
acquisition, either directly or indirectly, by Buyer of an interest in the
Receivables, excluding, however:

                           (i)      Indemnified Amounts to the extent a final
         judgment of a court of competent jurisdiction holds that such
         Indemnified Amounts resulted from gross negligence or willful
         misconduct on the part of the Indemnified Party seeking
         indemnification;

                           (ii)     Indemnified Amounts to the extent the same
         includes losses in respect of Receivables that are uncollectible on
         account of the insolvency, bankruptcy or lack of creditworthiness of
         the related Obligor; or

                           (iii)    taxes imposed by the jurisdiction in which
         such Indemnified Party's principal executive office is located, on or
         measured by the overall net income of such Indemnified Party to the
         extent that the computation of such taxes is consistent with the
         Intended Characterization;

provided, however, that nothing contained in this sentence shall limit the
liability of any Originator or limit the recourse of Buyer to any Originator for
amounts otherwise specifically provided to be paid by such Originator under the
terms of this Agreement. Without limiting the generality of the foregoing
indemnification, such Originator shall indemnify each Indemnified Party for
Indemnified Amounts (including, without limitation, losses in respect of
uncollectible receivables, regardless of whether reimbursement therefor would
constitute recourse to such Originator of Performance Guarantor) relating to or
resulting from:

                                    (A)      any representation or warranty made
                  by such Originator (or any officers of any such Originator)
                  under or in connection with this Agreement, any other
                  Transaction Document or any other information or report
                  delivered by any such Person pursuant hereto or thereto, which
                  shall have been false or incorrect when made or deemed made;

                                    (B)      the failure by such Originator to
                  comply with any applicable law, rule or regulation with
                  respect to any Receivable or Contract related thereto, or the
                  nonconformity of any Receivable or Contract included therein
                  with any such applicable law, rule or regulation or any
                  failure of such Originator to keep or perform any of its
                  obligations, express or implied, with respect to any Contract;

                                    (C)      any failure of such Originator to
                  perform its duties, covenants or other obligations in
                  accordance with the provisions of this Agreement or any other
                  Transaction Document;

                                       18



                                    (D)      any products liability, personal
                  injury or damage suit or other similar claim arising out of or
                  in connection with merchandise, insurance or services that are
                  the subject of any Contract or any Receivable;

                                    (E)      any dispute, claim, offset or
                  defense (other than discharge in bankruptcy of an Obligor) of
                  an Obligor to the payment of any Receivable (including,
                  without limitation, a defense based on such Receivable or the
                  related Contract not being a legal, valid and binding
                  obligation of such Obligor enforceable against it in
                  accordance with its terms), or any other claim resulting from
                  the sale of the merchandise or services related to such
                  Receivable or the furnishing or failure to furnish such
                  merchandise or services;

                                    (F)      the commingling of Collections of
                  Receivables at any time with other funds;

                                    (G)      any investigation, litigation or
                  proceeding related to or arising from this Agreement or any
                  other Transaction Document, the transactions contemplated
                  hereby, the use of the proceeds of any Purchase, the ownership
                  of the Receivables or any other investigation, litigation or
                  proceeding relating to such Originator in which any
                  Indemnified Party becomes involved as a result of any of the
                  transactions contemplated hereby;

                                    (H)      any inability to litigate any claim
                  against any Obligor in respect of any Receivable as a result
                  of such Obligor being immune from civil and commercial law and
                  suit on the grounds of sovereignty or otherwise from any legal
                  action, suit or proceeding;

                                    (I)      any Termination Event described in

                  title to, and ownership of, the Receivables, the Related
                  Security and the Collections, free and clear of any Adverse
                  Claim;

                  failure of Armstrong to acquire and maintain legal and
                  equitable title to, and ownership of any Receivable
                  transferred to it under the Sale and Assignment and the
                  Related Security and Collections with respect thereto from

                  Receivable, the Related Security and Collections with respect
                  thereto, and the proceeds of any thereof, whether at the time
                  of any Purchase or at any subsequent time;

                                       19



                                    (M)      any action or omission by such
                  Originator which reduces or impairs the rights of Buyer or its

                  (a)      No failure or delay on the part of Buyer (or its
assigns) in exercising any power, right or remedy under this Agreement shall
operate as a waiver thereof, nor shall any single or partial exercise of any
such power, right or remedy preclude any other further exercise thereof or the
exercise of any other power, right or remedy. The rights and remedies herein

take all actions, that may be

                                       20



necessary or reasonably desirable, or that Buyer (or its assigns) may reasonably
request, to perfect, protect or more fully evidence the interests of the Buyer
hereunder and the Purchaser Interests under the Purchase Agreement, or to enable
Buyer (or its assigns) to exercise and enforce their rights and remedies
hereunder. At any time, Buyer (or its assigns) may, direct an Originator to
notify the Obligors of Receivables originated by it, at such Originator's
expense, of the ownership interests of Buyer under this Agreement and may also

with respect to the Receivables as a financing statement in such offices as
Buyer (or its assigns) in their sole discretion deem necessary or desirable to
perfect and to maintain the perfection and priority of Buyer's and its assigns'
interests in the Receivables. This appointment is coupled with an interest and
is irrevocable.

or not having the force or effect of law).

                                       21



                  (c)      Anything herein to the contrary notwithstanding, each
of the Buyer, each Originator, each Indemnified Party and any successor or
assign of any of the foregoing (and each employee, representative or other agent
of any of the foregoing) may disclose to any and all Persons, without limitation

                            FORM OF SUBORDINATED NOTE

                                SUBORDINATED NOTE

                                                                   June 27, 2003

                  1.       Note. FOR VALUE RECEIVED, the undersigned, LPAC CORP.
II, a Delaware corporation ("SPV"), hereby unconditionally promises to pay to
the order of [NAME OF APPLICABLE ORIGINATOR], a [____] corporation
("Originator"), in lawful money of the United States of America and in
immediately available funds, on the date following the Amortization Date which
is one year and one day after the date on which (i) the Outstanding Balance of
all Receivables sold under the "Sale Agreement" referred to below has been
reduced to zero and (ii) Originator has paid to the Buyer all indemnities,
adjustments and other amounts which may be owed thereunder in connection with
the Purchases (the "Collection Date"), the aggregate unpaid principal sum
outstanding of all "Subordinated Loans" made from time to time by Originator to
SPV pursuant to and in accordance with the terms of that certain Receivables
Sale Agreement dated as of June 27, 2003 among Originator, [Names of other
Originators] and SPV (as amended, restated, supplemented or otherwise modified
from time to time, the "Sale Agreement"). Reference to Section 1.2 of the Sale
Agreement is hereby made for a statement of the terms and conditions under which
the loans evidenced hereby have been and will be made. All terms which are
capitalized and used herein and which are not otherwise specifically defined
herein shall have the meanings ascribed to such terms in the Sale Agreement or
the Purchase Agreement described below.

                  2.       Interest. SPV further promises to pay interest on the
outstanding unpaid principal amount hereof from the date hereof until payment in
full hereof at a rate equal to the Bank Rate; provided, however, that if SPV
shall default in the payment of any principal hereof, SPV promises to pay, on
demand, interest at the rate of the Bank Rate plus 2.00% per annum on any such
unpaid amounts, from the date such payment is due to the date of actual payment.
Interest shall be payable on the first Business Day of each month in arrears;
provided, however, that SPV may elect on the date any interest payment is due
hereunder to defer such payment and upon such election the amount of interest
due but unpaid on such date shall constitute principal under this Subordinated
Note. The outstanding principal of any loan made under this Subordinated Note
shall be due and payable on the Collection Date and may be repaid or prepaid at
any time without premium or penalty.

                  3.       Principal Payments. Originator is authorized and
directed by SPV to enter on the grid attached hereto, or, at its option, in its
books and records, the date and amount of each loan made by it which is
evidenced by this Subordinated Note and the amount of each payment of principal
made by SPV, and absent manifest error, such entries shall constitute prima
facie evidence of the accuracy of the information so entered; provided that
neither the failure of Originator to make any such entry or any error therein
shall expand, limit or affect the obligations of SPV hereunder.

                                     Exh.V-1



                  4.       Subordination. The indebtedness evidenced by this
Subordinated Note is subordinated to the prior payment in full of all of SPV's
recourse obligations under that certain Receivables Purchase Agreement dated as
of June 27, 2003 by and among SPV, Lennox Industries Inc., as Servicer, various
"Purchasers" from time to time party thereto, and Bank One, NA (Main Office
Chicago), as the "Agent" (as amended, restated, supplemented or otherwise
modified from time to time, the "Purchase Agreement"). The subordination
provisions contained herein are for the direct benefit of, and may be enforced
by, the Agent and the Purchasers and/or any of their respective assignees
(collectively, the "Senior Claimants") under the Purchase Agreement. Until the
date on which all "Capital" outstanding under the Purchase Agreement has been
repaid in full and all other obligations of SPV and/or the Servicer thereunder
and under the "Fee Letter" referenced therein (all such obligations,
collectively, the "Senior Claim") have been indefeasibly paid and satisfied in
full, Originator shall not demand, accelerate, sue for, take, receive or accept
from SPV, directly or indirectly, in cash or other property or by set-off or any
other manner (including, without limitation, from or by way of collateral) any
payment or security of all or any of the indebtedness under this Subordinated
Note or exercise any remedies or take any action or proceeding to enforce the
same; provided, however, that (i) Originator hereby agrees that it will not
institute against SPV any proceeding of the type described in Section 5.1(d) of
the Sale Agreement unless and until the Collection Date has occurred and (ii)
nothing in this paragraph shall restrict SPV from paying, or Originator from
requesting, any payments under this Subordinated Note so long as SPV is not
required under the Purchase Agreement to set aside for the benefit of, or
otherwise pay over to, the funds used for such payments to any of the Senior
Claimants and further provided that the making of such payment would not
otherwise violate the terms and provisions of the Purchase Agreement. Should any
payment, distribution or security or proceeds thereof be received by Originator
in violation of the immediately preceding sentence, Originator agrees that such
payment shall be segregated, received and held in trust for the benefit of, and
deemed to be the property of, and shall be immediately paid over and delivered
to the Agent for the benefit of the Senior Claimants.

                  5.       Bankruptcy; Insolvency. Upon the occurrence of any
proceeding of the type described in Section 5.1(d) of the Sale Agreement
involving SPV as debtor, then and in any such event the Senior Claimants shall
receive payment in full of all amounts due or to become due on or in respect of
Capital and the Senior Claim (including "CP Costs" and "Yield" as defined and as
accruing under the Purchase Agreement after the commencement of any such
proceeding, whether or not any or all of such CP Costs or Yield is an allowable
claim in any such proceeding) before Originator is entitled to receive payment
on account of this Subordinated Note, and to that end, any payment or
distribution of assets of SPV of any kind or character, whether in cash,
securities or other property, in any applicable insolvency proceeding, which
would otherwise be payable to or deliverable upon or with respect to any or all
indebtedness under this Subordinated Note, is hereby assigned to and shall be
paid or delivered by the Person making such payment or delivery (whether a
trustee in bankruptcy, a receiver, custodian or liquidating trustee or
otherwise) directly to the Agent for application to, or as collateral for the
payment of, the Senior Claim until such Senior Claim shall have been paid in
full and satisfied.

                  6.       Amendments. This Subordinated Note shall not be
amended or modified except in accordance with Section 7.1 of the Sale Agreement.
The terms of this Subordinated Note may not be amended or otherwise modified
without the prior written consent of the Agent for the benefit of the
Purchasers.

                  7.       GOVERNING LAW. THIS SUBORDINATED NOTE HAS BEEN MADE
AND DELIVERED AT CHICAGO, ILLINOIS, AND SHALL BE INTERPRETED AND THE RIGHTS AND
LIABILITIES OF THE PARTIES HERETO DETERMINED IN ACCORDANCE WITH THE LAWS AND
DECISIONS OF THE STATE OF ILLINOIS. WHEREVER POSSIBLE EACH PROVISION OF THIS
SUBORDINATED NOTE SHALL BE INTERPRETED IN SUCH MANNER AS TO BE EFFECTIVE AND
VALID UNDER APPLICABLE LAW, BUT IF ANY PROVISION OF THIS SUBORDINATED NOTE SHALL
BE PROHIBITED BY OR INVALID UNDER APPLICABLE LAW, SUCH PROVISION SHALL BE
INEFFECTIVE TO THE EXTENT OF SUCH PROHIBITION OR INVALIDITY, WITHOUT
INVALIDATING THE REMAINDER OF SUCH PROVISION OR THE REMAINING PROVISIONS OF THIS
SUBORDINATED NOTE.

                  8.       Waivers. All parties hereto, whether as makers,
endorsers, or otherwise, severally waive presentment for payment, demand,
protest and notice of dishonor. Originator additionally expressly waives all
notice of the acceptance by any Senior Claimant of the subordination and other
provisions of this Subordinated Note and expressly waives reliance by any Senior
Claimant upon the subordination and other provisions herein provided.

                  9.       Assignment. This Subordinated Note may not be
assigned, pledged or otherwise transferred to any party without the prior
written consent of the Agent, and any such attempted transfer shall be void.
