Item 2.  ACQUISITION OR DISPOSITION OF ASSETS.

    On January 24, 1997, ACR Group, Inc., a Texas corporation ("the 
Company"), entered into a Purchase Agreement ("Agreement") pursuant to which, 
effective January 1, 1997, the Company acquired all of the issued and 
outstanding capital stock of Lifetime Filter, Inc., a Texas corporation 
("LFI") and, contemporaneously therewith, LFI acquired substantially all of 
the assets, and assumed substantially all of the liabilities, of O'Leary 
Family Partnership, Ltd., a Texas limited partnership ("OFP") associated with 
the business of OFP as a manufacturer and distributor of electrostatic air 
filters sold directly to heating, ventilation and air conditioning 
contractors.  Prior to such transactions, Mr. Richard O'Leary ("O'Leary") was 
the sole shareholder of both LFI and RGO, Ltd. Co., the general partner of 
OFP.

    On the closing date, the Company paid $1,280,622 to O'Leary and OFP, and 
LFI issued a promissory note ("Note") to OFP for $1,280,622.  The aggregate 
consideration of $2,561,244 ("Purchase Price") was determined as a multiple 
of the unaudited combined net income for the year ended December 31, 1996, of 
LFI and Lifetime Filter Manufacturing, Ltd. ("LFM") (the assets of which were 
transferred to, and the liabilities of which were assumed by, OFP on December 
31, 1996).  The Agreement provides that the Purchase Price may subsequently 
be adjusted based on the results of an independent audit of LFI and LFM to be 
performed with respect to their fiscal year ended December 31, 1996.  The 
Purchase Price may also be subsequently reduced if LFI fails to sell a 
specified dollar volume of filters during 1997.

    The Note bears interest at the prime rate plus 1% per annum.  The Note is 
to be repaid in twelve equal installments of principal, plus accrued 
interest. The Note matures on December 31, 1999.  The Note is secured by a 
first lien on certain production equipment of LFI and the land and building 
on which LFI's plant is situated, and by a junior lien on the accounts 
receivable and inventory of LFI.  The Note is subordinated to the Company's 
indebtedness to its senior secured lender.

    All of the cash paid by the Company to O'Leary came from a portion of the 
proceeds of a $1.4 million loan to the Company from St. James Capital 
Partners, L.P.

    The assets of LFI are all used in connection with its business of 
manufacturing and distributing electrostatic air filters.  The Company 
intends to continue using LFI's assets for such purpose.

    Pursuant to the Agreement, LFI and O'Leary entered into a Consulting 
Agreement for a period of one year.  The Consulting Agreement also restricts 
O'Leary from competing with LFI for a period of three years following its 
expiration.

                                     -1-

Item 7.  FINANCIAL STATEMENTS, PRO FORMA FINANCIAL INFORMATION AND EXHIBITS.

    At the present time, it is impracticable to provide either the financial 
statements of LFI and OFP or pro forma financial information relative to the 
acquisition as required by this Item 7.  The Company will file such financial 
statements and pro forma financial information by amendment to this Form 8-K 
as soon as practicable, but not later than April 9, 1997.

                               PURCHASE AGREEMENT


     THIS PURCHASE AGREEMENT (this "Agreement") is entered into effective as 
of January 1, 1997 by and among ACR GROUP, INC., a Texas corporation 
("ACRG"), and RICHARD O'LEARY ("O'Leary"), the holder of all of the 
outstanding capital stock of LIFETIME FILTER, INC., a Texas corporation 
("LFI"), LFI and O'LEARY FAMILY PARTNERSHIP, LTD., a Texas limited 
partnership ("OFP").

                                    ARTICLE I

                     TRANSFER OF STOCK; TRANSFER OF ASSETS;
                        ASSUMPTION OF CERTAIN LIABILITIES

     1.1  TRANSFER OF STOCK; TRANSFER OF ASSETS; ASSUMPTION OF CERTAIN 
LIABILITIES. The parties hereto acknowledge that, during the period from 
January 1, 1993 through December 31, 1996, the business of manufacturing and 
selling heating and air conditioning filters and related products was 
conducted by Lifetime Filter Manufacturing, Ltd., a Texas limited liability 
company ("LFM"), the members of which are currently  O'Leary and OFP, owning 
1% and 99% of the membership interests of LFM, respectively. LFM conducted 
this business pursuant to an agreement between LFM and LFI authorizing LFM to 
manufacture and sell such products under the "LifeTime Filter" trademark. On 
December 31, 1996, LFM assigned and transferred all of its assets to its 
members and all of its liabilities were assumed by OFP. Promptly thereafter, 
O'Leary contributed his interest in such assets to OFP.  On January 3, 1997, 
O'Leary ceased to be the general partner of OFP and RGO, Ltd. Co., a Texas 
limited liability company, became the new general partner of OFP. Commencing 
January 1, 1997, the business activities formerly conducted by LFM have been 
conducted by OFP. Subject to the terms and conditions of this Agreement, (a) 
O'Leary will sell, transfer, assign and deliver to ACRG on the Closing Date 
(hereafter defined) 1,000 shares of the common stock, $1.00 per share par 
value, of LFI, constituting all of the issued and outstanding shares of the 
capital stock of LFI (the "Stock"), and (b) OFP will sell, transfer, assign 
and deliver to LFI on the Closing Date all of the assets and other tangible 
and intangible personal property of OFP, including but not limited to those 
described on EXHIBIT A hereto, excluding, however, those items specifically 
excluded by reference on EXHIBIT A hereto (the "Assets"), free and clear of 
all security interests, liens, claims and encumbrances, and LFI shall 
purchase, accept and acquire the Assets from OFP, and LFI shall assume those 
certain liabilities (and none other) of OFP listed on EXHIBIT B hereto (the 
"Assumed Liabilities"). Any provision in this Agreement to the contrary 
notwithstanding, it is understood and agreed that the Assets do not include 
any assets (tangible or intangible) used in the development or manufacture of 
a lawn sprinkler product in the form of a helicopter which has been developed 
by O'Leary. All assets related to the development and manufacture of the lawn 
sprinkler product are the property of O'Leary.  The payment in full at the 
Closing (hereafter defined) of the accounts receivable of OFP from O'Leary in 
the amount of $50,763 constitutes full and final payment by O'Leary for the 
assets related to the development and manufacture of such lawn sprinkler 
product.

     1.2  CONSIDERATION FOR THE STOCK AND THE ASSETS.  Subject to the terms 
and conditions of this Agreement, and as full consideration for the Stock and 
the Assets and the covenants, representations, warranties and indemnities 
made in connection herewith by O'Leary, LFI and OFP, ACRG shall pay to 
O'Leary the sum of $500,000.00 for the Stock (the "Stock Purchase Price"), 
and ACRG shall cause LFI to pay to OFP an amount (the "Asset Purchase Price") 
equal to (a) four (4) times the net income of LFM for the year ended December 
31, 1996 ("1996 Income") as determined in accordance with generally accepted 
accounting principles and as certified by an independent audit to be by 
conducted Ernst & Young, LLP ("E & Y") (the "Audit"), less (b) the Stock 
Purchase Price.  The cost of the Audit shall be paid by ACRG. Upon completion 
of the Audit, ACRG shall provide a copy of the audited 1996 income statement 
to OFP, together with a calculation of any adjustment to the Asset Purchase 
Price. OFP shall have full access to all documents, workpapers or other 
materials produced or reviewed by E & Y in the conduct of the Audit.  Should 
OFP disagree with any such adjustment to the Asset Purchase Price, as to 
which resolution thereof is not reached between ACRG and OFP within thirty 
(30) days after delivery of a copy of the audited 1996 income statement to 
OFP, any remaining disputed matters shall be submitted to a national 
accounting firm selected by mutual agreement between ACRG and OFP, whose 
decision with respect to any disputed item shall be final and binding on the 
parties hereto.  The expense of engaging such accounting firm to resolve such 
disputed items arising in connection with the Audit shall be borne by OFP. 
For purposes of determining 1996 Income, it is agreed that there shall be 
deducted therefrom the aggregate amount of the accounts receivable of OFP 
which remain unpaid as of the end of the calendar month preceding the Closing 
Date and have an invoice date earlier than one hundred twenty (120) days 
prior to the Closing Date ("Delinquent Receivables").  If LFI shall collect 
any amounts of the Delinquent Receivables during the one-year period 
following the Closing Date, such amounts collected (including amounts 
collected after the end of such one-year period pursuant to an installment 
payout arrangement with respect to any Delinquent Receivable which may have 
been entered into with the approval of OFP during such one-year period (a 
"Payout Agreement")), less the collection expense incurred by LFI in 
connection therewith, shall be paid by LFI to OFP. Such payments, if any, 
shall be deemed to be an increase in the Asset Purchase Price (but not an 
increase in 1996 Income) and shall be paid in cash within thirty (30) days 
after the end of each calendar quarter with respect to amounts collected 
during the calendar quarter. OFP shall have the right from time to time to 
review the books and records of LFI during such one-year period for the 
purpose of verifying compliance by LFI with the provisions of the preceding 
two sentences. LFI shall follow customary collection procedures used by 
subsidiary corporations of ACRG to attempt to collect such Delinquent 
Receivables; however, neither ACRG nor LFI shall be liable to OFP for any 
Delinquent Receivables which are not collected. OFP shall have the right to 
contact obligors on Delinquent Receivables in order to attempt to obtain 
payment thereof.  Any Delinquent Receivables that may be collected following 
the expiration of one-year period after the Closing Date, other than amounts 
collected pursuant to a Payout Agreement, shall be retained by LFI and shall 
not be deemed to be an increase in the Purchase Price (or an increase in 1996 
income). The sum of the Stock Purchase Price and the Asset Purchase Price is 
hereinafter referred to as the "Total Purchase Price".  The Asset Purchase 
Price shall be allocated to the Assets by LFI in the manner determined by it 
in the reasonable exercise of its business judgment and OFP shall cooperate 
with LFI in the execution and filing of appropriate documents with the 
internal Revenue Service to confirm such


                                      2
<PAGE>

allocation.

     1.3  PAYMENT OF STOCK PURCHASE PRICE. The Stock Purchase Price shall be 
paid by ACRG in full at the Closing by certified check or wire transfer.

     1.4  PAYMENT OF ASSET PURCHASE PRICE.  A tentative Asset Purchase Price
(the "Tentative Asset Purchase Price") shall be determined in accordance with
the formula set forth in Section 1.2 of this Agreement, with net income of LFM
for such purpose being determined by the unaudited financial statements of LFM,
which shall have been prepared in accordance with generally accepted accounting
principles. The Tentative Asset Purchase Price shall be paid at the Closing as
follows:

          (a)  An amount equal to (i) fifty percent (50%) of the Total Purchase
               Price less (ii) the Stock Purchase Price, shall be paid by LFI to
               OFP at the Closing by certified check or wire transfer; and

          (b)  LFI shall issue its promissory note (the "Note") payable to OFP
               in the original principal amount equal to fifty percent (50%) of
               the Total Purchase Price. The Note shall be in the form attached
               hereto as EXHIBIT C and shall be (i) guaranteed by ACRG pursuant
               to a guaranty agreement (the "Guaranty") in the form attached
               hereto as EXHIBIT D, (ii) subordinated to indebtedness of ACRG to
               NationsBank of Texas, N.A. (or such successor lender thereto),
               pursuant to applicable provisions relating thereto contained in
               the Note and the subordination agreement (the "Subordination
               Agreement") in the form attached hereto as EXHIBIT E, (iii)
               secured by a lien on the Assets granted pursuant to a security
               agreement (the "Security Agreement") in the form attached hereto
               as EXHIBIT F, which lien shall be subordinated to the lien
               thereon of NationsBank of Texas, N.A. (or such successor lender
               thereto), and (iv) further secured by a deed of trust (the "Deed
               of Trust") in the form attached hereto as EXHIBIT G covering the
               land, buildings and improvements owned by LFI within which the
               business activities of OFP have been conducted (the "Facility").

Upon completion of the Audit, and any dispute resolution procedure invoked by 
OFP pursuant to Section 1.2 hereof, if any, the Asset Purchase Price shall be 
determined and the difference between the Asset Purchase Price and the 
Tentative Asset Purchase Price (the "Adjustment Amount") shall be paid 
promptly as follows:

          (y)  If the Adjustment Amount is positive, LFI shall pay OFP fifty
               percent (50%) of the Adjustment Amount by certified check or wire
               transfer and the original principal amount of the Note shall be
               increased by fifty percent (50%) of the Adjustment Amount and a
               substitute Note shall be issued in exchange for the Note issued
               at the Closing in order to reflect


                                     3
<PAGE>

               the inclusion of the Adjustment Amount therein and the 
               corresponding modification of the amount of the remaining 
               quarterly principal payments on the Note (after giving effect
               to the principal payments theretofore made on the Note).  Such 
               substitute Note shall be dated as of the Closing Date and shall 
               be effective from and after the Closing Date.

          (z)  If the Adjustment Amount is negative, the original principal
               amount of the Note shall be decreased by the entire Adjustment
               Amount and a substitute Note shall be issued in exchange for the
               Note issued at the Closing in order to reflect the deduction of
               the Adjustment Amount therefrom and the corresponding
               modification of the amount of the remaining quarterly principal
               payments on the Note (after giving effect to the principal
               payments theretofore made on the Note). Such substitute Note
               shall be dated as of the Closing Date and shall be effective from
               and after the Closing Date.

No adjustment shall be made to the principal amount of the Note until such 
time as the Audit, and any dispute resolution procedure invoked by OFP 
pursuant to Section 1.2 hereof, if any, are finally concluded. All payments 
due under the Note shall be made in accordance with the terms of the Note 
notwithstanding the fact that payments may become due on the Note prior to 
completion of the Audit, and any dispute resolution procedures invoked by OFP 
pursuant to Section 1.2 hereof.

     1.5  DISCLAIMER OF LIABILITY. Except for the Assumed Liabilities, 
neither LFI nor ACRG shall assume or be responsible for any claims against or 
liabilities, commitments, contracts, agreements or obligations whatsoever of 
LFM or OFP, including without limitation any liability of LFM or OFP as an 
employer or under any contract of employment, and OFP will at all times 
indemnify and hold LFI and ACRG harmless from and against any claim therefor 
or liability arising therefrom. Neither LFI nor ACRG shall have any liability 
for any sales, use, income, franchise or other tax or charge, if any, which 
may become payable in connection with the sale of the Assets by OFP pursuant 
to this Agreement or any other taxes or charges arising out of the operation 
of the business of LFM or OFP at any time prior to the Closing Date, and all 
such taxes shall be duly and timely paid by OFP.

     1.6  ADJUSTMENT TO ASSET PURCHASE PRICE.  In the event that the dollar 
sales volume of filters ("Filter Sales") made by both LFI (after the Closing 
Date) and OFP (prior to the Closing Date) during the calendar year ended 
December 31, 1997 ("1997 Filter Sales") is less than ninety-five percent 
(95%) of the amount of Filter Sales made by OFP during the calendar year 
ended December 31, 1996 ("1996 Filter Sales"), the Asset Purchase Price shall 
be retroactively reduced by an amount equal to the Goodwill Adjustment, 
determined as follows:

Goodwill Adjustment = Goodwill-[Goodwill x (1997 Filter Sales Divided By 0.95)]
                                            ------------------
                                            1996 Filter Sales


                                      4
<PAGE>

For purposes of this Section 1.6, "Goodwill" shall be the amount by which the
Asset Purchase Price exceeds the owner's equity of LFM, as determined by the
Audit. In the event that 1997 Filter Sales include sales by LFI to ACRG or any
of its subsidiaries or affiliates which are at prices below that charged by LFI
to parties other than ACRG, its subsidiaries and affiliates, for purposes of
determining the Goodwill Adjustment, 1997 Filter Sales shall be increased to the
amount that would have resulted if the sales prices charged to ACRG, its
subsidiaries and affiliates had been the same as those charged to such
unaffiliated parties.

     If the amount of the Goodwill Adjustment is greater than $100,000, the then
outstanding principal amount of the Note shall be reduced by the amount of the
Goodwill Adjustment and a substitute note reflecting the new principal amount
shall be substituted for the Note, and the scheduled payments under the Note
shall be redetermined (after giving effect to the principal payments theretofore
made on the Note). If the amount of the Goodwill Adjustment is less than or
equal to $100,000, the then outstanding principal amount of the Note shall be
reduced and a substitute note reflecting the new principal amount thereof shall
be substituted for the Note; however, the scheduled payments under the new Note
shall be the same as those under the Note issued at the Closing, which would
result in the Note being paid in full at an earlier date.

     The determination of the amount of the Goodwill Adjustment pursuant to this
Section 1.6 and the substitution of the Note shall be completed on or before
January 31, 1998.

     In order to facilitate 1997 Filter Sales, LFI agrees to maintain a sales
and marketing effort for the sale of filters during calendar year 1997 at least
equivalent to the sales and marketing effort for the sale of filters during
calendar year 1996 made by LFM.  Attached hereto as EXHIBIT H are the agreed
minimum elements of the sales and marketing efforts to be undertaken by LFI for
the sale of filters during calendar year 1997. If LFI performs at least the
minimum elements of the sales and marketing efforts so specified, it shall be
deemed to have fully complied with its obligations pursuant to this paragraph of
Section 1.6. In the event that LFI does not perform at least the minimum
elements of the sales and marketing efforts so specified, as the sole remedy to
OFP and O'Leary, ACRG shall not be entitled to any retroactive adjustment to the
Asset Purchase Price, as provided in the first paragraph of this Section 1.6, as
a result of 1997 Filter Sales being less than 95% of 1996 Filter Sales.

     1.7  INSTRUMENTS OF TRANSFER. OFP will deliver to LFI at the Closing (in
addition to the other documents provided for in this Agreement) such deeds,
bills of sale, endorsements, assignments and other good and sufficient
instruments of conveyance, transfer and assignment, in form and substance
satisfactory to counsel for ACRG, as shall be effective to vest in LFI good and
marketable title to the Assets.  All certificates representing the Stock
delivered to ACRG pursuant to Section 1.1 shall be duly endorsed in blank, or
accompanied by duly executed stock powers in blank, and otherwise in proper form
for transfer. Upon the consummation of the purchase of the Stock by ACRG from
O'Leary, the Stock shall be reissued in the name of ACRG.


                                       5
<PAGE>

     1.8  FURTHER ASSURANCES. From time to time after the Closing, at the
request of ACRG or LFI, but without further consideration, OFP and O'Leary will
execute and deliver such other instruments of conveyance and transfer and take
such other action as ACRG or LFI reasonably may require more effectively to vest
title to the Assets in LFI and to the Stock in ACRG.

     1.9  CLOSING.  The closing of the transactions provided for herein (the
"Closing") shall take place at 12:00 noon C.S.T. at the office of counsel to
ACRG, 820 Gessner, Suite 1360, Houston, Texas on January 24, 1997.  The date of
the Closing is referred to in this Agreement as the Closing Date.

     2.7  FINANCIAL STATEMENTS.  O'Leary, LFI and OFP have previously 
furnished to ACRG the combined balance sheets of LFI and LFM as of December 
31, 1994, December 31, 1995, and December 31, 1996 (the "1996 Balance Sheet 
Date") (collectively, the "Balance Sheets" and, as to the Balance Sheet dated 
December 31, 1996, the "1996 Balance Sheet"), and combined income statements 
("Income Statements") for the two (2) years ended December 31, 1995 and 
December 31, 1996 (the Balance Sheets and the Income Statements are 
collectively referred to herein as the "Financial Statements").  The Balance 
Sheets fairly present the combined financial position of LFI and LFM, as of 
the date thereof and the Income Statements fairly present the combined 
results of operations of LFI and LFM, for the periods set forth therein. The 
Financial Statements have been prepared in accordance with generally accepted 
accounting principles consistently applied by LFI and LFM during the periods 
involved.

     2.8  RECEIVABLES.  Other than the Delinquent Receivables, the accounts 
and notes receivable of LFI and LFM shown on the 1996 Balance Sheet have been 
collected or are current and collectible in the aggregate recorded amounts, 
less any reserve shown on the 1996 Balance Sheet.

     2.9  INVENTORIES. The inventories of LFM shown on the 1996 Balance Sheet 
consist of items of a quantity and a quality usable or salable in the normal 
course of the business of LFM and the values at which such inventories are 
carried reflect the normal inventory valuation policy of LFM stating the 
inventories at the lower of cost or market on a first-in-first-out basis. The 
fair market value of the inventories shown on the 1996 Balance Sheet is not 
less than the values at which such inventories are carried on the 1996 
Balance Sheet.

     2.10 ABSENCE OF UNDISCLOSED LIABILITIES. Except as and to the extent 
reflected or reserved against in the 1996 Balance Sheet, as of the 1996 
Balance Sheet Date, to the best current actual knowledge of OFP, LFI and 
O'Leary, neither of LFI or LFM had any liabilities or obligations of any 
nature (whether absolute, accrued, contingent or otherwise), including, 
without limitation, any liabilities resulting from failure to comply with any 
law applicable to either of LFI or LFM or any tax liabilities due or to 
become due and whether incurred in respect or measured by the income or sales 
of either of LFI or LFM for any period prior to the close of business on the 
1996 Balance Sheet Date, or arising out of any transaction entered into, or 
any state of facts existing, prior thereto. To the best current actual 
knowledge of OFP, LFI and O'Leary, there is no basis for any assertion 
against either of LFI or LFM, as of the 1996 Balance Sheet Date, of any 
liabilities of any nature or in any amount not fully reflected or reserved 
against in the 1996 Balance Sheet.

     2.11 ABSENCE OF CHANGES. Except as described in the First six sentences 
of Section 1.1 of this Agreement, since the 1996 Balance Sheet Date, there 
has not been (a) any material adverse change in the financial condition, 
business, prospects, operations, properties, assets or liabilities (whether 
direct, indirect, accrued, absolute, contingent or otherwise) of any of LFI, 
LFM or OFP other than changes in the ordinary course of business, none of 
which have been materially adverse; (b) any damage, destruction or loss, 
whether covered by insurance or not, materially and adversely affecting the 
properties and business of any of LFI, LFM or OFP; (c)

<PAGE>

disposition by any of LFI, LFM or OFP of any interest in its properties, 
excluding inventory sold in the ordinary course of business, and specifically 
including but not limited to any machinery, equipment or other operating 
property, any patent, trademark, service mark, trade name, brand name, 
copyright (or pending application for any patent, trademark, service mark or 
copyright), invention, process, know-how, formula, pattern, design, trade 
secret or interest thereunder or other intangible asset; or (d) any dispute 
or any other occurrence, event or condition of any character, which 
reasonably could be anticipated to give rise to a legal or administrative 
action or to a material adverse effect upon the condition (financial or 
otherwise), business, prospects, operations, properties, assets or 
liabilities (whether direct, indirect, accrued, absolute, contingent or 
otherwise) of any of LFI, LFM or OFP (whether or not covered by insurance).

     2.12 AGREEMENTS, CONTRACTS AND COMMITMENTS.  Except as set forth on 
SCHEDULE 2.12, (a) none of LFI, LFM or OFP is a party to or bound by any 
written or oral contract, agreement or commitment or instrument which relates 
to any of the Assets or the Stock or any loan or credit agreement, security 
agreement, guaranty, indenture, mortgage, pledge, conditional sale or title 
retention agreement, equipment obligation, lease purchase agreement or other 
instrument evidencing indebtedness; (b) each such contract and commitment 
constitutes the legal and binding agreement of the parties thereto, 
enforceable in accordance with its terms; (c) none of LFI, LFM or OFP has 
breached any material provision of, or is in default in any material respect 
under the terms of, any such contract, agreement or commitment, and no event 
has occurred which, after notice or lapse of time or both, would constitute 
such a material default under the terms of any such contract, agreement or 
commitment; (d) no other party to any such contract, agreement or commitment 
to which any of LFI, LFM or OFP is a party or by which any of LFI, LFM or OFP 
is bound is in default thereunder or in breach of any term or provision 
thereof; and (e) there exist no conditions or events which, after notice or 
lapse of time or both, would constitute a default by any party to any such 
contract, agreement or commitment.

     2.13 TAX MATTERS. LFI, LFM and OFP have previously delivered to ACRG 
true, correct and complete copies of all of their respective federal income 
tax, and, if applicable, state franchise tax returns for each of the years

or thereafter. All federal, state, county and local tax returns and tax 
reports required to be filed by either of LFI or LFM prior to the date hereof 
are true, correct and complete and have been filed with the appropriate 
governmental agencies in all jurisdictions in which such returns and reports 
are required to be filed. All federal, state, county and local income and 
other taxes, including interest and penalties thereon, due from either of LFI 
or LFM have been fully paid or adequately provided for by either LFI or LFM. 
The provision for taxes in the 1996 Balance Sheet is sufficient for the 
payment of all unpaid federal, state, county and local taxes, including 
interest and penalties thereon, whether or not disputed, accrued or 
applicable, for the period then ended and for all years prior thereto.  No 
federal income tax return of either of LFI or LFM is being audited by the 
Internal Revenue Service ("IRS"). There are no pending questions raised in 
writing by the IRS or other taxing authority relating to, nor claims asserted 
in writing by the IRS or other taxing authority for, taxes or assessments of 
either

of LFI or LFM nor are there any outstanding agreements or waivers extending 
the statutory period of limitation applicable to any tax return of either of 
LFI or LFM for any period. No sales tax, use tax or other transfer tax of any 
type whatsoever is required to be paid by ACRG or any of LFI, LFM or OFP with 
respect to the transfer of the Stock or the Assets as provided herein.

any interests therein, to which any of LFI, LFM or OFP is a party or by which 
any of LFI, LFM or OFP or any property of any of LFI, LFM or OFP is in any 
way bound or affected, together with all amendments and supplements thereto 
and modifications thereof.  All such contracts, agreements, mortgages, 
concessions, leases, commitments, amendments, supplements and modifications 
are legally valid and binding and in full force and effect, and there are and 
will be no defaults thereunder.

leasehold or other interest in tangible personal property will be impaired by

of such rights will be enforceable by LFI after the Closing without the 
consent or agreement of any other party.

                                INDEMNIFICATION

     6.1  INDEMNIFICATION BY OFP AND O'LEARY. OFP and O'Leary shall, jointly 
and severally, indemnify and hold ACRG and LFI harmless from and against and 
in respect of all Damages, as hereinafter defined. "Damages", as used in this 
Section 6.1, shall include without limitation any claim, action, demand, 
loss, cost, expense, liability, whether joint or several, penalty, and other 
damage, including without limitation attorneys' fees and other costs and 
expenses reasonably incurred in investigating, and attempting to avoid, or in 
opposing the imposition thereof, resulting to ACRG or LFI, directly or 
indirectly, from (a) any inaccurate representation or warranty by or on 
behalf of OFP, LFI or O'Leary in, or pursuant to the provisions of this 
Agreement, (b) the breach or default in the performance by OFP, LFI or 
O'Leary of any of the obligations to be performed by or on behalf of OFP, LFI 
or O'Leary, as applicable hereunder (unless such breach or default in 
performance occurred on or before the Closing Date and this Agreement was 
terminated because of such breach or default in performance, in which case 
ACRG and LFI shall be deemed to have waived any right under this Section 6.1 
to indemnification for Damages caused by such breach or default in 
performance), (c) from any liability of OFP which has not been assumed by LFI 
hereunder, or (d) any breach or default in the performance of any obligation 
to be performed by or on behalf of LFI, LFM, 



                                       21
<PAGE>

OFP or O'Leary before the Closing Date, which results in a claim being 
asserted against ACRG or LFI. OFP and O'Leary shall, in addition, reimburse 
ACRG or LFI on demand for any payment made by ACRG or LFI at any time after 
the Closing based upon the final judgment of any court of competent 
jurisdiction or pursuant to a bona fide compromise or settlement of any such 
claim, demand, or action, in respect of any Damages to which the foregoing 
indemnity relates. If any third party shall assert any such claim against 
ACRG or LFI which, if successful, might result in a breach or default by OFP 
or O'Leary, then ACRG or LFI shall give prompt written notice thereof to OFP 
and O'Leary and OFP and O'Leary shall be entitled to elect, within ten (10) 
days after the giving of such notice, to provide the defense thereof and to 
be represented, at the sole expense of OFP and O'Leary, by counsel selected 
by OFP and O'Leary. In the event OFP or O'Leary make such election, ACRG or 
LFI shall have the right to participate in such defense, at their sole 
expense. Neither ACRG nor LFI shall compromise or settle any such claim 
without giving OFP and O'Leary ten (10) days written notice thereof if the 
effect of any such compromise or settlement would require indemnification by 
OFP and O'Leary for all or any part of the amount of such compromise or 
settlement and receipt of the express written consent of OFP or O'Leary to 
such compromise or settlement, which shall not be unreasonably delayed or 
withheld. Any notice or reply thereto required under this Section 6.1 shall 
be made in accordance with the provisions of Section 8.4 hereof.

     6.2  INDEMNIFICATION BY ACRG. ACRG shall indemnify and hold OFP and 
O'Leary harmless against and in respect of all Damages, as hereinafter 
defined. "Damages", as used in this Section 6.2, shall include without 
limitation any claim, action, demand, loss, cost, expense, liability, whether 
joint or several, penalty, and other damage, including, without limitation, 
attorneys' fees and other costs and expenses reasonably incurred in 
investigating, and attempting to avoid, or in opposing the imposition 
thereof, resulting to OFP or O'Leary from (a) any inaccurate representation 
by or on behalf of ACRG in or pursuant to the provisions of this Agreement, 
(b) the breach or default in performance by ACRG of any of the obligations to 
be performed by or on behalf of ACRG hereunder (unless such breach or default 
in performance occurred on or before the Closing Date and this Agreement was 
terminated because of such breach or default in performance, in which case 
OFP and O'Leary shall be deemed to have waived any rights under this Section 
6.2 to indemnification for Damages caused by such breach or default in 
performance) or (c) any breach or default by ACRG or LFI in the performance 
of any obligation to be performed by or on behalf of ACRG or LFI after the 
Closing Date, which results in a claim being asserted against OFP or O'Leary. 
ACRG shall, in addition, reimburse OFP and O'Leary on demand for any payment 
made by OFP and O'Leary at any time after the Closing Date, based upon the 
final judgment of any court of competent jurisdiction or pursuant to a bona 
fide compromise or settlement of any such claim, demand, or action, in 
respect of any Damages to which the foregoing indemnity relates. If any third 
party shall assert any such claim against OFP and O'Leary which, if 
successful, might result in a breach or default by ACRG, then OFP and O'Leary 
shall give prompt written notice thereof to ACRG, and ACRG shall be entitled 
to elect, within ten (10) days after the giving of such notice, to provide 
the defense thereof and to be represented, at the sole expense of ACRG, by 
counsel to be selected by ACRG. In the event ACRG makes such election, OFP 
and O'Leary shall have the right to participate in such defense, at their 
sole expense. Neither OFP nor O'Leary shall compromise 



                                       22
<PAGE>

or settle any such claim without giving ACRG ten (10) days written notice 
thereof if the effect of any such compromise or settlement would require 
indemnification by ACRG for all or any part of the amount of such compromise 
or settlement and receipt of the express written consent of ACRG and LFI to 
such compromise or settlement, which shall not be unreasonably delayed or 
withheld.  Any notice or reply thereto required under this Section 6.2 shall 
be made in accordance with the provisions of Section 8.4 hereof.

     6.3  LIMITATION ON INDEMNIFICATION. The provisions of Sections 6.1 and 
6.2 shall terminate and expire two (2) years after the Closing Date.

     (c)  BY ACRG.  By ACRG if any of the conditions specified in Sections 5.1
          and 5.2 of this Agreement have not been satisfied and shall not have

          terminate this Agreement, without any liability to O'Leary, LFI and
          OFP, if ACRG shall determine that the transactions contemplated by
          this Agreement have become inadvisable or impracticable by reason of
          any litigation or proceeding instituted by any government or agency
          thereof.

     7.2  NOTICE OF TERMINATION.  In the event that any party hereto 
exercises its right to terminate this Agreement in accordance with the 
provisions of Section 7.1 hereinabove, such election shall be effective only 
when notice of such election is given to each of the other parties hereto, in 
writing, in accordance with the provisions of Section 8.4 hereof.

shall be terminated pursuant to the provisions of Section 7.1 hereof, this

terminate without further liability of any party to another, except as

statements of fact contained in any memorandum, certificate, instrument, 
schedule, or other document delivered by or on behalf of O'Leary, LFI and 
OFP, on the one hand, or ACRG, on the other hand, for the information of, or 
reliance by, the other party to this Agreement pursuant hereto, shall be 
deemed to be representations and warranties by the party delivering same.  
All representations, warranties and covenants, including covenants of 
indemnification, made by the parties and contained in this Agreement shall 
survive the Closing and all inspections, examinations, or audits on behalf of 
the parties for a period of two (2) years after the Closing Date.

Agreement, this Agreement may be amended, modified or supplemented only by

hand, or O'Leary, LFI and OFP, on the other hand, to comply with any

LFI, OFP and ACRG, respectively, only by a written instrument signed by the 
party granting such waiver, but such waiver or failure to insist upon strict 
compliance with such obligation, covenant, agreement or condition shall not 
operate as a waiver of, or estoppel with respect to, any subsequent or other 
failure.  Whenever this Agreement requires or permits consent by or on behalf 
of any party hereto, such consent shall be given in writing in a manner 
consistent with the requirements for a waiver of compliance as set forth in

     4.   SECURITY.  Maker's obligations under this note are secured by the
Security Agreement of even date herewith made by and between Maker and Payee and

security provided for in the Security Agreement and the Deed of Trust.

     5.   NO USURY INTENDED; SPREADING. Notwithstanding any provision to the 
contrary contained in this note or any of the other Credit Documents, it is 
expressly provided that in no case or event shall the aggregate of (i) all 
interest on the unpaid balance of this note, accrued or paid from the date 
hereof and (ii) the aggregate of any other amounts accrued or paid pursuant 
to this note or any of the other Credit Documents, which under applicable 
laws are or may be deemed to constitute interest upon the indebtedness 
evidenced by this note from the date hereof, ever exceed the Ceiling Rate. In 
this connection, Maker and Payee stipulate and agree that it is their common 
and overriding intent to contract in strict compliance with applicable usury 
laws. In furtherance thereof, none of the terms of this note or any of the 
other Credit Documents shall ever be construed to create a contract to pay, 
as consideration for the use, forbearance or detention of money, interest at a 
rate in excess of the Ceiling Rate. Maker or other parties now or hereafter 
becoming liable for payment of the indebtedness evidenced by this note shall 
never be liable for interest in excess of the Ceiling Rate. If, for any 
reason whatever, the interest paid or received on this note during its full 
term produces a rate which exceeds the Ceiling Rate, the holder of this note 
shall credit against the principal of this note (or, if such indebtedness 
shall have been paid in full, shall refund to the payor of such interest) 
such portion of said interest as shall be necessary to cause the interest 
paid on this note to produce a rate equal to the Ceiling Rate. All sums paid 
or agreed to be paid to the holder of this note for the use, forbearance or 
detention of the indebtedness evidenced hereby shall, to the extent permitted 
by applicable law, be amortized, prorated, allocated and spread in equal 
parts throughout the full

term of this note, so that the interest rate is uniform throughout the full 
term of this note. The provisions of this Section 5 shall control all 
agreements, whether now or hereafter existing and whether written or oral, 
between Maker and Payee.

     6.   DEFAULT. Subject to the provisions of Section 7 hereof, the 
occurrence of any of the following events shall constitute default under this 
note, whereupon the owner or holder hereof may, at its, his or her option, 
exercise any or all rights, powers and remedies afforded under the Security 
Agreement, the Deed of Trust or any of the Credit Documents and by law, 
including the right to declare the unpaid balance of principal and accrued 
interest on this note at once mature and payable:

     (a)  any part of the Debt is not paid when due, whether by lapse of time 
          or acceleration or otherwise, unless Payee declares the default fully
          cured to Payee's satisfaction within ten (10) calendar days after such
          due date.

     (b)  any Obligor fails to perform, observe or comply with, or defaults
          under, any of the material terms, covenants, conditions or provisions
          contained in this note or any other Credit Documents (other than any
          such failure or default described in one of the other subsections of
          this section) unless Payee declares the failure or default fully cured
          to Payee's satisfaction within thirty (30) calendar days after Payee
          has given Maker written notice thereof (such grace period to run
          concurrently with, and not in addition to, any other grace periods
          provided for in any other Credit Documents with respect to the same
          default).

     (c)  any Obligor: (i) commences a voluntary case in bankruptcy or a
          voluntary petition seeking reorganization or to effect a plan or other
          arrangement with creditors; (ii) makes an assignment for the benefit
          of creditors; (iii) applies for or consents to the appointment of any
          receiver or trustee for any such party or for any substantial portion
          of its property; or (iv) makes an assignment to an agent authorized to
          liquidate any substantial part of its assets.

     (d)  in respect of any Obligor: (i) an involuntary case shall be commenced
          with any court or other authority seeking liquidation, reorganization
          or a creditor's arrangement of any such party, and such action shall
          not have been dismissed within sixty (60) days after its filing; or
          (ii) an order of any court or other authority shall be entered
          appointing any receiver or trustee for any such party or for any
          substantial portion of its property.



                                                                  INITIALLED FOR

     7.   SUBORDINATION.  Payee agrees that no payment other than regularly 
scheduled payments of principal and interest due on this note shall be made 
by Maker without the prior written consent of NationsBank of Texas, N.A.. 
secured lender (or such successor lender thereto) (the "Senior Lender") of 
ACR Group, Inc., a Texas corporation and parent company of Maker ("ACRG") to 
which ACRG may be indebted from time to time (the "Senior Indebtedness").  
Payee further agrees that no payments whatsoever shall be received on this 
note, and no action with respect to the collateral securing this note shall 
be taken, during the period of ninety (90) consecutive days after the date on 
which the Senior Indebtedness shall be declared by the Senior Lender to be in 
default. Thereafter, Payee may take action in respect of a default on this 
note or the collateral securing this note without regard to any declared 
default by the Senior Lender on the Senior Indebtedness; PROVIDED, however, 
that Payee shall take no such action so long as there is no default in the 
payment of the Debt. Should such a default by ACRG on the Senior Indebtedness 
be cured by ACRG or waived by the Senior Lender, the payment obligations of 
Maker hereunder shall be reinstated, until the occurrence of a subsequent 
default on the Senior Indebtedness, and Maker shall pay to Payee on the next 
scheduled installment payment date hereunder all amounts regularly scheduled 
to be due on such installment payment date along with all amounts that would 
have been paid by Maker to Payee hereunder during the period of default on 
the Senior Indebtedness had the subordination provisions of the preceding 
sentence not been in effect. This note is subject to the terms of a 
Subordination Agreement among the Senior Lender, ACRG and Payee.

     8.   NO WAIVER BY PAYEE. No delay or omission of Payee or any other 
holder hereof to exercise any power, right or remedy accruing to Payee or any 
other holder hereof shall impair any such power, right or remedy or shall be 
construed to be a waiver of the right to exercise any such power, right or 
remedy.

     9.   COSTS AND ATTORNEYS' FEES.  If any holder of this note retains an 
attorney in connection with any default or to collect, enforce or defend 
this note or any of the Credit Documents in any lawsuit or in any probate, 
reorganization, bankruptcy or other proceeding, or if Maker sues any holder 
in connection with this note or any of the Credit Documents and does not 
prevail, then Maker agrees to pay to each such holder, in addition to 
principal and interest, all reasonable costs and expenses incurred by such 
holder in trying to collect this note or in any such suit or proceeding, 
including reasonable attorneys' fees. An amount equal to ten percent (10%) of 
the unpaid principal and accrued interest owing on this note when and if this 
note is placed in the hands of an attorney for collection after default is 
stipulated to be reasonable attorneys' fees unless a holder or Maker timely 
pleads otherwise to a court of competent jurisdiction. 



                                                                  INITIALLED FOR

severally waive notice (including, but not limited to, notice of intent to 
accelerate and notice of acceleration, notice of protest and notice of 
dishonor), demand, presentment for payment, protest, diligence in collecting 
and the filing of suit for the purpose of fixing liability and consent that 
the time of payment hereof may be extended and reextended from time to time 
without notice to any of them. Each such person agrees that his, her or its 
liability on or with respect to this note shall not be affected by any 
release of or change in any guaranty or security at any time existing or by 
any failure to perfect or maintain perfection of any lien against or security 
interest in any such security or the partial or complete unenforceability of 
any guaranty or other surety obligation, in each case in whole or in part, 
with or without notice and before or after maturity.

     11.  VENUE: CHOICE OF LAW. This note shall be governed by and construed 
in accordance with the laws of the State of Texas and the United States of 
America from time to time in effect. Harris County, Texas shall be a proper 
place of venue for suit hereon. Maker and any and all co-makers, endorsers,

district courts of Harris County, Texas, or the United States District Court 
for the Southern District of Texas, Houston Division. Maker hereby 
irrevocably submits to the nonexclusive jurisdiction of the state and federal

agreements contained herein shall be binding upon, and shall inure to the 
benefit of, the respective legal representatives, heirs, successors and

     14.  SEVERABILITY.  If any provision of this note is held to be illegal, 
invalid or unenforceable under present or future laws, the legality, validity 
and enforceability of the remaining provisions of this note shall not be 
affected thereby, and this note shall be liberally 



                                                                  INITIALLED FOR

                                    GUARANTY


     THIS GUARANTY (this "Guaranty") is executed and delivered effective as 
of this ____ day of January, 1997, by ACR GROUP, INC., a Texas corporation 
("Guarantor"), in favor of O'LEARY FAMILY PARTNERSHIP, LTD., a Texas limited 
partnership ("OFP").

     WHEREAS, Guarantor desires to guarantee to OFP payment of certain 
obligations, upon the terms and conditions set forth below.

     NOW, THEREFORE, in consideration of ten dollars ($10.00) and other good 
and valuable consideration, Guarantor hereby agrees as follows:

     1.   Guarantor hereby agrees to and does guarantee the full, prompt and 
punctual payment of any and all payment obligations of LIFETIME FILTER, INC, 
a Texas corporation and wholly owned subsidiary of Guarantor ("Debtor"), to 
OFP which may arise as a result of the failure by Debtor to repay certain 
indebtedness (the "Debt") owed by Debtor to OFP as evidenced by that certain 
promissory note in the original principal amount of $___________ (The 
"Note"), dated January 24, 1997, upon the terms and conditions contained in 
the Note. This Guaranty shall be conditioned upon demand by OFP upon Debtor 
for payment, which demand shall not have been satisfied within thirty (30) 
days after such demand. Subject to the foregoing, this Guaranty is 
irrevocable and absolute and if for any reason all or any portion of the Debt 
shall not be paid when due, Guarantor will immediately pay the Debt to OFP.

     2.   Guarantor hereby agrees, upon request from time to time by OFP or 
any subsequent holder of the Note, to provide to OFP or any subsequent holder 
of the Note a copy of the loan agreement and all ancillary documents thereto 
and any modifications thereof made by and between NationsBank of Texas, N.A. 
(or such successor lender thereto) and Guarantor evidencing the indebtedness 
of Guarantor to such lender (the "Senior Indebtedness"). Further, Guarantor 
hereby agrees to notify OFP or any subsequent holder of the Note promptly in 
the event of a declared default by Guarantor under the Senior Indebtedness 
which prohibits any action by OFP or any subsequent holder of the Note in 
collecting any amounts due under the Note. Additionally, Guarantor hereby 
agrees to use its best efforts to cure any declared default on the Senior 
Indebtedness.

     3.   Failure by Guarantor to pay any part of the Debt when due, subject 
to the terms of this Guaranty, shall constitute default under this Guaranty.

     4.   Guarantor's agreements and obligations under this Guaranty shall in 
no way be released, diminished, reduced, impaired or otherwise affected by 
extension of time for payment of or any other alteration of the Debt, by 
settlement or compromise of any or all of the Debt, or by occurrence of any 
other event or circumstances which might otherwise constitute a defense 
available to, or discharge of, Guarantor.

(without regard to any conflict-of-law provisions thereof).

     6.   This Guaranty shall not be changed orally but shall be changed only 
be agreement in writing signed by Guarantor and OFP. Any consent with respect

shall be of the essence and that Secured Party's acceptance of a partial or
delinquent payment or payments, or the failure of Secured Party to exercise any

     For value received and to secure payment of the note, Grantor conveys the
property to Trustee in trust.  Grantor warrants and agrees to defend the title
to the property. If Grantor performs all the covenants and pays the note
according to its terms, this deed of trust shall have no further effect, and
Beneficiary shall release it at Grantor's expense.

GRANTOR'S OBLIGATIONS
     Grantor agrees to:
           1.  keep the property in good repair and condition;
           2.  pay all taxes and assessments on the property when due;
           3.  preserve the lien's priority as it is established in this deed of
               trust;

           4.  maintain, in a form acceptable to Beneficiary, an insurance
               policy that:
               a.   covers all improvements for their full insurable value as
                    determined when the policy is issued and renewed, unless
                    Beneficiary approves a smaller amount in writing;
               b.   provides fire and extended coverage, including windstorm
                    coverage;
               c.   protects Beneficiary with a standard mortgage clause;
               d.   provides flood insurance at any time the property is in a
                    flood hazard area; and
           5.  upon request by the Beneficiary, deliver the insurance policy to
               Beneficiary and deliver renewals to Beneficiary at least ten days
               before expiration;
           6.  keep any buildings occupied as required by the insurance policy;
               and
           7.  if this is not a first lien, pay all prior lien notes that
               Grantor is personally liable to pay and abide by all prior lien
               instruments.

BENEFICIARY'S RIGHTS
           1.  Beneficiary may appoint in writing a substitute or successor
               trustee, succeeding to all rights and responsibilities of
               Trustee.

                                      2
<PAGE>


           2.  If the proceeds of the note are used to pay any debt secured by
               prior liens, Beneficiary is subrogated to all of the rights and
               liens of the holders of any debt so paid.
           3.  Beneficiary may apply any proceeds received under the insurance
               policy either to reduce the note or to repair or replace damaged
               or destroyed improvements covered by the policy.
           4.  If Grantor fails to perform any of Grantor' obligations,
               Beneficiary may perform those obligations and be reimbursed by
               Grantor on demand at the place where the note is payable for any
               sums so paid, including attorney's fees, plus interest on those
               sums from the dates of payment at the rate stated in the note for
               matured, unpaid amounts.  The sum to be reimbursed shall be
               secured by this deed of trust.
           5.  If Grantor defaults on the note or fails to perform any of
               Grantor's obligations or if default occurs on a prior lien, note
               or other instruments, and the default continues after Beneficiary
               gives Grantor notice of default and the time within which it must
               be cured, as may be required by law or by written agreement, then
               Beneficiary may:
               a.   declare the unpaid principal balance and earned interest in
                    the note immediately due;
               b.   request Trustee to foreclose this lien, in which case
                    Beneficiary or Beneficiary's agent shall give notice of the
                    foreclosure sale as provided by the Texas Property Code as
                    then amended; and
               c.   purchase the property at any foreclosure sale by offering
                    the highest bid and then have the bid credited on the note.


TRUSTEE'S DUTIES
     If requested by Beneficiary to foreclose this lien, Trustee shall:
           1.  either personally or by agent give notice of the foreclosure sale
               as required by The Texas Property Code as then amended;
           2.  sell and convey all or part of the property to the highest bidder
               for cash with a general warranty binding Grantor, subject to
               prior liens and to other exceptions to conveyance and warranty;
               and
           3.  from the proceeds of the sale, pay, in this order:
               a.   expenses of foreclosure, including a commission to Trustee
                    of 5% of the bid;
               b.   to Beneficiary, the full amount of principal, interest,
                    attorney's fees and other charges due and unpaid;
               c.   any amounts required by law to be paid before payment to
                    Grantor; and
               d.   to Grantor, any balance.


GENERAL PROVISIONS
           1.  If any of the property is sold under this deed of trust, Grantor
               shall immediately surrender possession to the purchaser. If
               Grantor fails to do so, Grantor shall 

                                      3
<PAGE>

               become a tenant at sufferance of the purchaser, subject to an 
               action for forcible detainer.
           2.  Recitals in any Trustee's deed conveying the property will be
               presumed to be true.
           3.  Proceeding under this deed of trust, filing suit for foreclosure,
               or pursuing any other remedy will not constitute an election of
               remedies.
           4.  This lien shall remain superior to liens later created even if
               the time of payment of all or part of the note is extended or 
               part of the property is released.
           5.  If any portion of the note cannot be lawfully secured by this
               deed of trust, payments shall be applied first to discharge that
               portion.
           6.  Grantor assigns to Beneficiary all sums payable to or received by
               Grantor from condemnation of all or part of the property, from
               private sale in lieu of condemnation, and from damages caused by
               public works or construction on or near the property. After
               deducting any expenses incurred, including attorney's fees,
               Beneficiary may release any remaining sums to Grantor or apply
               such sums to reduce the note.  Beneficiary shall not be liable
               for failure to collect or to exercise diligence in collecting any
               such sums.
           7.  Grantor assigns to Beneficiary absolutely, not only as
               collateral, all present and future rent and other income and
               receipts from the property.  Leases are not assigned.  Grantor
               warrants the validly and enforceability of the assignment.
               Grantor may as Beneficiary's licensee collect rent and other
               income and receipts so long as Grantor is not in default under
               the note or this deed of trust. Grantor will apply all rent and
               other income and receipts to payments of the note and performance
               of this deed of trust, but if the rent and other income and
               receipts exceed the amount due under the note and the deed of
               trust, Grantor may retain the excess.  If Grantor defaults in
               payment of the note or performance of this deed of trust,
               Beneficiary may terminate Grantor's license to collect and then
               as Grantor's agent may rent the property if it is vacant and
               collect all rent and other income and receipts.  Beneficiary
               neither has nor assumes any obligations as lessor or landlord
               with respect to any occupant of the property. Beneficiary may
               exercise Beneficiary's rights and remedies under this paragraph
               without taking possession of the property. Beneficiary shall
               apply all rent and other income and receipts collected under this
               paragraph first to expenses incurred in exercising Beneficiary's
               rights and remedies and then to Grantor's obligations under the
               note and this deed of trust in the order determined by
               Beneficiary. Beneficiary is not required to act under this
               paragraph, and acting under this paragraph does not waive any of
               Beneficiary's other rights or remedies.  If Grantor becomes a
               voluntary or involuntary bankrupt, Beneficiary's filing a proof
               of claim in bankruptcy will be tantamount to the appointment of a
               receiver under Texas law.
           8.  Interest on the debt secured by this deed of trust shall not
               exceed the maximum amount of nonusurious interest that may be
               contracted for, taken, reserved, charged, or received under law;
               any interest in excess of that maximum amount shall be credited
               on the principal of the debt or, if that has been paid, refunded.
               On any acceleration or required or permitted prepayment, any such
               excess shall 

                                      4
<PAGE>

               be canceled automatically as of the acceleration or prepayment 
               or, if already paid, credited on the principal of the debt or, 
               if the principal of the debt has been paid, refunded. This 
               provision overrides other provisions in this and all other
               instruments concerning the debt.
           9.  When the context requires, singular nouns and pronouns include
               the plural.
           10. The term NOTE includes all sums secured by this deed of trust.
           11. This deed of trust shall bind, inure to the benefit of, and be
               exercised by successors in interest of all parties.
           12. If Grantor and Maker are not the same person, the term Grantor
               shall include Maker.

           EXECUTED on the day and year first set forth above.

                          [CAGLE EMPLOYMENT AGREEMENT] 









<PAGE>

                     EMPLOYMENT AND NONCOMPETITION AGREEMENT

     THIS EMPLOYMENT AND NONCOMPETITION AGREEMENT (the "Agreement") is entered
into by and between Lifetime Filter, Inc., a Texas corporation having its
principal place of business at 1005 Katyland Drive, Katy, Texas 77493 (the
"Company"), and James Cagle ("Employee"), who resides at 24222 Kuykendahl,
Tomball, Texas 77375.  Employee acknowledges and agrees that the Company has
required that Employee enter into this Agreement and agree to the terms and
provisions hereof, including in particular Articles III and IV hereof, as a
condition to the Company's employment of Employee.

                                    ARTICLE I

     Employee agrees to be employed by the Company, and the Company agrees to
employ Employee, as President of the Company for the purpose of performance by
and on behalf of the Company of such services commensurate with that position as
may be requested from time to time by the board of directors of the Company. At
all times while employed by the Company, Employee shall perform his employment
duties, and exclusively serve and promote the business interests of the Company,
in good faith, with fidelity and loyalty, with his full, best and dedicated
efforts, in compliance with all rules, policies, practices, directives and
procedures of the Company.

                                   ARTICLE II

     The initial term of this Agreement shall begin on the date hereof and
terminate on December 31, 2001, provided that a party seeking to terminate this
Agreement shall have given the other party not less than sixty (60) days' notice
of such termination. Absent such notice of termination, at the end of the
initial term of this Agreement, this Agreement shall be automatically renewed
for additional one-year terms each successive year until such year as one party
gives notice of termination to the other party not less than sixty (60) days
prior to expiration of that one-year term.

     During Employee's employment hereunder, the Company shall pay to Employee
the compensation and benefits set forth on Exhibit A, attached hereto and
incorporated herein for all purposes. Employee is not entitled to severance
compensation benefits upon the termination of his employment with the Company
(whether voluntary or involuntary).

     The employment, compensation and benefit arrangements hereunder shall be
terminated upon the occurrence of the first to occur of any of the following
events:

           (1) The expiration of the term of this Agreement; or

<PAGE>

           (2) Employee's death, or such physical or mental disability or
     incapacity of Employee which, in the reasonable opinion of the Company,
     causes Employee to be unable to effectively perform his duties hereunder
     for a continuous period of one hundred eighty (180) days, in either of
     which events all unaccrued compensation and benefits payable pursuant to
     the terms hereof shall cease; or

           (3) Written notice of dismissal with Cause (as hereinafter defined)
     by the Company, given to Employee at any time and effective as stated in
     such notice, in which event all unaccrued compensation and benefits payable
     pursuant to the terms hereof shall cease upon such dismissal; or

           (4) Upon mutual agreement of the parties hereto in writing.

     Termination for "Cause" is defined as termination for any of the following
     reasons:

           (a) If Employee has performed any of his duties under this Agreement
     in a grossly negligent manner, breached any material provision of this
     Agreement, or violated any statutory or common law duty of loyalty to the
     Company;

           (b) If Employee has engaged in malfeasance, theft from the Company,
     embezzlement or is convicted of a felony;

           (c) If Employee has engaged in dishonesty, fraud or willful
     disloyalty with respect to the assets or business of the Company or matters
     affecting the employment relationship;

           (d) If the Company shall fall to attain at least seventy percent
     (70%) of the aggregate Forecast Income (as defined in Exhibit A) for any
     period of two consecutive fiscal years during the term of this Agreement.

     On any voluntary termination of this Agreement by Employee, or pursuant to
the preceding paragraphs 2, 3 and 4 hereinabove, other than as of the end of the
Company's fiscal year, Employee shall not be entitled to any bonus for such 
partial fiscal year. In addition, the Company is excused from performing its
compensation obligations to Employee for so long as, and to the extent that,
Employee is receiving disability benefits under a disability insurance policy
maintained by the Company.  Upon a voluntary termination of this Agreement by
Employee or a termination of Employee's employment for Cause by the Company, all
future compensation to which Employee would otherwise be entitled and all future
benefits for which Employee would otherwise be eligible shall cease and

<PAGE>

in EXHIBIT A hereto) ONLY, payable on a periodic basis consistent with the 
payroll practices of the Company through the remainder of the term of this 
Agreement (it being understood and agreed that such termination of employment 
shall also constitute notice of termination to Employee, as hereinabove 
provided, to be effective at the end of the term of employment then in 
effect). The Company shall be entitled to reduce the amount of compensation 
to be paid to Employee pursuant to the provisions of the preceding sentence 
by an amount equal to the compensation paid to Employee pursuant to any 
subsequent employment which may be entered into by Employee.  Employee's 
rights pursuant to the provisions of the second preceding sentence shall be 
Employee's sole and exclusive rights against the Company or its affiliates, 
and the Company's and its affiliates' sole and exclusive liability to 
Employee under this Agreement, in contract, tort, or otherwise, for any 
termination of Employee's employment hereunder other than for Cause.

                                   ARTICLE III

     Employee recognizes and agrees that the business of the Company and its
business interests require a confidential relationship between it and its
employees and the fullest practical protection and confidential treatment of its
trade secrets, trade practices, prospects, transactions, customers and other
knowledge of the business or financial affairs of the Company that will be or
have been conceived, developed or learned by Employee during Employee's course
of employment with the Company. Accordingly, Employee agrees that during
Employee's term of employment with the Company and during the applicable period
of the noncompetition provision described in Article IV hereof, Employee will:

           (1) Keep secret and confidential all such information, trade secrets,
     trade practices, prospects, transactions, customer lists, and business
     practices of the Company (written or unwritten), and Employee shall not
     divulge, disclose or reveal for any reason or in any manner to any person
     who is not an officer, director or employee of either the Company, ACR
     Group, Inc., or any other direct or indirect subsidiary of ACR Group, Inc.
     (collectively the "Consolidated Group") any of the foregoing information,
     including the following: (a) information identifying or tending to identify
     any of the customers, suppliers or employees of the Company or any member
     of the Consolidated Group; (b) information concerning the intellectual
     property of the Company or any other member of the Consolidated Group,
     including all patents, trademarks, trade names, service marks and
     copyrighted materials; and all ideas, designs, methods, concepts,
     advertising and promotional materials, and computer programs, software and
     source codes, whether or not protected under any law; and (c) information
     pertaining to the plans, products, services, processes, prospects,
     procedures, techniques, and financial statements, forecasts and projections
     of the Company or any other member of the Consolidated Group; but excluding
     information that (i) has been disclosed by the Company or any other member
     of the Consolidated Group to the public or as may have been required by
     law, or by a court of competent jurisdiction, or to respond to a valid
     inquiry by a governmental authority, or (ii) has been received by Employee
     from a third party without breaching 

                                      3
<PAGE>

     an obligation owed to the Company, or (iii) has been disclosed to a third 
     party by the Company without similar restriction; and

           (2) Not use or aid others in using, directly or indirectly, the same
     in competition with the Company, unless required by a valid order of a
     court or other governmental authority of competent jurisdiction; and

           (3) Other than on behalf of the Company's interests, Employee shall
     not (a) offer, induce, solicit, influence, or attempt to influence any
     employee of the Company or any other member of the Consolidated Group to
     terminate his or her employment for the purpose of working for a competitor
     of the Company or any other member of the Consolidated Group; (b) influence
     or attempt to influence any agent, customer or supplier who has a business
     relationship with the Company or any other member of the Consolidated Group
     to cease or adversely alter that business relationship; or (c) contact,
     solicit or do business with any person who is, or has been at any time
     during the two years preceding the effective date of Employee's termination
     of employment with the Company, a customer of the Company or any other
     member of the Consolidated Group, for the purpose of diverting, soliciting
     or accepting any business in competition with the Company or any other
     member of the Consolidated Group.

     In addition, after ceasing for any reason to be employed by the Company,
Employee shall not retain or remove, without the Company's advance written
consent, any list, data, book, record, manual, drawing, document, schedule,
source code, specification, computer tape, program, diskette or software, or
other written or recorded information pertaining to the business and financial
affairs of the Company or any other member of the Consolidated Group, except for
items that are strictly personal (such as tax forms, payroll slips, and
Employee's copy of this Agreement).

     Employee further agrees that all inventions, ideas, plans, prospects or
processes or other results of the efforts of Employee's employment by the
Company which are conceived, invented or developed, in whole or in part, by or
with the assistance of Employee during Employee's employment with the Company,
shall be the sole and exclusive property of the Company, and Employee shall,
upon request from the Company at any time, execute such confirmatory assignments
of the same or similar documents in favor of the Company.

                                   ARTICLE IV

     In consideration of the compensation payable to Employee hereunder, during
the term of this Agreement and for a period of one (1) year after termination of
this Agreement by either Employee or the Company, the Employee will not,
directly or indirectly, engage in the business of manufacturing air filters and
marketing and distributing same to dealers or contractors located anywhere in
the United States and Canada through means of direct mail advertising and sale,

                                      4
<PAGE>

as such activities were conducted by the Company prior to and during the term of
this Agreement (the "Business"), or become affiliated as an agent, advisor,
partner, officer, director, employee, proprietor, consultant, stockholder or
independent contractor with any person or entity directly or indirectly engaged
in the Business. The provisions of the preceding sentence shall not be
applicable if Employee's employment hereunder is terminated by the Company
without Cause.  This restriction applies to any passive investment in securities
of any corporation or other business organization, unless the Employee's equity
ownership is less than 1%. Employee further agrees that during his term of
employment hereunder, he will devote full business time and best efforts to the
business and affairs of the Company.

     Employee makes the preceding covenants in consideration for, and as a
necessary condition of, his employment by the Company. Employee's obligations to
the Company under this section are independent of any obligation of the Company
or any other member of the Consolidated Group to Employee (including any
obligation under this Agreement or any other agreement between Employee and the
Company or any obligation that otherwise derives arises from any aspect of the
employment relationship) and are not subject to any set-off, defense, deduction
or counterclaim based on any claim that Employee may have against the Company or
any other member of the Consolidated Group. The restrictive covenants of
Employee set forth in this section will survive the termination of this
Agreement for the periods specified above and are assignable by the Company to
any assignee or successor in interest to its business.

     Employee expressly acknowledges that the Company conducts business
throughout the United States and Canada, and he stipulates that the time and
area restrictions of the foregoing obligations do not unduly oppress the
Employee's future employment opportunities. In addition, Employee acknowledges
that the restrictions set forth in Articles III and IV are reasonable
limitations necessary to protect the legitimate business interests of the
Company and the Consolidated Group in guarding the trade secrets, preserving the
goodwill of its customers and business, preventing solicitation of its existing
customers, obtaining the benefit of unique employee training and education, and
preventing unauthorized use of its proprietary or confidential business lists,
records and information.

     The duration of every obligation set forth above will be extended by any
period of time during which Employee is in breach of the obligation.  To the
extent that the duration, geographical area, or scope of activity of any of the
preceding restrictions would cause them to be unenforceable in a particular
jurisdiction, the restrictions automatically will be reformed for purposes of
enforcement in that jurisdiction to a duration, geographical area, or scope of
activity that is valid and enforceable in that jurisdiction.  Reformation of a
restriction to validate its enforcement in any particular jurisdiction, however,
will not affect the enforcement of the restriction as stated in any other
jurisdiction in which it is enforceable as stated.  Also, the invalidity of a
restriction in a particular jurisdiction will not affect the validity or
enforcement of the restriction in another jurisdiction where it is otherwise
valid.

                                   ARTICLE V


     If Employee becomes indebted to the Company for any reason during the 
term of his employment, the Company may (but is not obligated to) setoff and 
collect any amount due the Company from Employee out of any compensation or 
expense reimbursement that it owes to Employee.

     Employee stipulates that a breach by him of any of the restrictive 
covenants set forth in Articles III and IV of this Agreement will diminish 
the value of the Company and the Consolidated Group and will cause 
irreparable and continuing injury to the Company and the Consolidated Group 
for which an adequate legal remedy will not exist. Accordingly, Employee 
stipulates that if he breaches any restrictive covenant set forth in Article 
III or IV of this Agreement, the Company will not be obligated to pay to 
Employee any remaining compensation specified in this Agreement and, without 
limiting or excluding any other available remedy, the Company and every other 
member of the Consolidated Group which is affected by the breach will be 
entitled to the following remedies: (a) the entry by a court having 
jurisdiction of an order granting specific performance or temporary 
injunctive relief, upon the posting of a bond of $1,500 and the filing with 
the court of an appropriate pleading and affidavit specifying each obligation 
breached by Employee, but without proof of actual monetary damage; (b) if a 
court having jurisdiction determines for any reason that the Company or other 
member of the Consolidated Group is not entitled to an injunction or specific 
performance, the recovery from Employee of all consequential damages 
attributable to his breach of the restrictive covenant and all profit, 
remuneration, or other consideration that Employee gains from breaching the 
restrictive covenant; and (c) reimbursement from Employee of all costs 
incurred by the Company and every other member of the Consolidated Group in 
enforcing the restrictive covenant or otherwise defending or prosecuting any 
legal proceeding arising out of the restrictive covenant. The Company may 
exercise any of the foregoing remedies concurrently, independently, or 
successively.

     In the event any provisions hereof shall be modified or held ineffective 
by any Court in any respect, such adjudication shall not invalidate or render 
ineffective the balance of the provisions hereof, and the provisions hereof 
shall be enforced to the maximum extent allowed by law.  This Agreement shall 
be governed by the laws of the State of Texas and shall be enforceable in 
Harris County, Texas. The Company may assign this Agreement (including the 
restrictive covenants set forth in Articles III and IV) to anyone who 
succeeds to the Company's business pursuant to a merger of purchase of all or 
substantially all of the Company's assets. The members of the Consolidated 
Group are third-party beneficiaries of Employee's obligations under Articles 
III and IV, and those obligations are enforceable by them to the same extent 
as if they were parties to this Agreement.

     This Agreement shall be binding upon and inure to the benefit of the 
parties hereto and their respective successors, assigns, heirs and personal 
representatives. The parties hereto have read the terms and conditions of 
this Agreement before signing the same, and hereby agree that no statement, 
agreement or understanding, whether oral or written, not contained herein 
will be 



                                      6

recognized or enforced. This Agreement may not be amended except by a written 
agreement executed by the Company and Employee which makes specific reference

       last trading price for the Stock for the ten (10) consecutive trading
       days prior to and including the last day of the fiscal year in

   with the business of the Company.  The Company shall provide all insurance
   coverage and repairs and maintenance for such vehicle and shall reimburse

                                    SECTION V


                                 NONCOMPETITION


     In consideration of the compensation payable to O'Leary hereunder, during
the term of this Agreement and for a period of three (3) years after termination
of this Agreement by either O'Leary or the Company, O'Leary will not, directly
or indirectly, engage in the business of manufacturing air filters and marketing
and distributing same to dealers or contractors located anywhere in the United
States and Canada through means of direct mail advertising and sale, as such
activities were conducted by the Company prior to and during the term of this
Agreement (the "Business"), or become affiliated as an agent, advisor, partner,
officer, director, employee, proprietor, consultant, stockholder or independent
contractor with any person or entity directly or indirectly engaged in the
Business. The provisions of the preceding sentence shall not be applicable if
O'Leary's services hereunder are terminated by the Company without Cause. This
restriction applies to any passive investment in securities of any corporation
or other business organization, unless equity ownership is less than 1%.

     O'Leary makes the preceding covenants in consideration for, and as a
necessary condition of, his engagement by the Company. O'Leary's obligations to
the Company under this section are independent of any obligation of the Company
or any other member of the Consolidated Group to O'Leary (including any
obligation under this Agreement or any other agreement between O'Leary and the
Company or any obligation that otherwise arises from any aspect of the
consulting relationship) and are not subject to any set-off, defense, deduction
or counterclaim based on any claim that O'Leary may have against the Company or
any other member of the Consolidated Group. The restrictive covenants of O'Leary
set forth in this section will survive the termination of this Agreement for the
periods specified above and are assignable by the Company to any assignee or
successor in interest to its business.

     O'Leary expressly acknowledges that the Company conducts business
throughout the United States and Canada and he stipulates that the time and area
restrictions of the foregoing obligations do not unduly oppress O'Leary's future
employment or consulting opportunities. In addition, O'Leary acknowledges that
the restrictions set forth in Sections IV and V are reasonable limitations
necessary to protect the legitimate business interests of the Company and the
Consolidated Group in guarding the trade secrets, preserving the goodwill of its
customers and business, preventing solicitation of its existing customers,
obtaining the benefit of unique employee training and education, and preventing
unauthorized use if its proprietary or confidential business lists, records and
information.

     The duration of every obligation set forth above will be extended by any
period of time during which O'Leary is in breach of the obligation.  To the
extent that the duration, geographical area, or scope of activity of any of the
preceding restrictions would cause them to be unenforceable in a particular
jurisdiction, the restrictions automatically will be reformed for purposes of
enforcement in that jurisdiction to a duration, geographical area, or scope of
activity that is valid and enforceable in that jurisdiction.  Reformation of a
restriction to validate its 


                                       4

<PAGE>

enforcement in any particular jurisdiction, however, will not affect the 
enforcement of the restriction as stated in any other jurisdiction in which 
it is enforceable as stated.  Also, the invalidity of a restriction in a 
particular jurisdiction will not affect the validity or enforcement of the 
restriction in another jurisdiction where it is otherwise valid.

     The provisions of this Section V shall become void and of no further force
and effect in the event of a payment default under that certain promissory note
executed by the Company and payable to the order of O'Leary Family Partnership,
Ltd. (the "Note"), which default is not cured by the Company within ninety (90)
days after its occurrence; PROVIDED, however, that in the event the Company
subsequently cures the payment default under the Note and O'Leary has not yet
commenced business in competition with the Company, then the provisions of this
Section V shall be reinstated in full.



                                   SECTION VI

                               REMEDIES FOR BREACH


     If O'Leary becomes indebted to the Company for any reason during the term
of this Agreement, the Company may (but is not obligated to) setoff and collect
any amount due the Company from O'Leary out of any compensation or expense
reimbursement that it owes to O'Leary.

     O'Leary stipulates that a breach by him of any of the restrictive covenants
set forth in Sections IV and V of this Agreement will diminish the value of the
Company and the Consolidated Group and will cause irreparable and continuing
injury to the Company and the Consolidated Group for which an adequate legal
remedy will not exist. Accordingly, O'Leary stipulates that if he breaches any
restrictive covenant set forth in Section IV or V of this Agreement, the Company
will not be obligated to pay to O'Leary any remaining compensation specified in
this Agreement and, without limiting or excluding any other available remedy,
the Company and every other member of the Consolidated Group which is affected
by the breach will be entitled to the following remedies: (a) the entry by a
court having jurisdiction of an order granting specific performance or temporary
injunctive relief, upon the posting of a bond of $1,500 and the filing with the
court of an appropriate pleading and affidavit specifying each obligation
breached by O'Leary, but without proof of actual monetary damage; (b) if a court
having jurisdiction determines for any reason that the Company or other member
of the Consolidated Group is not entitled to an injunction or specific
performance, the recovery from O'Leary of all consequential damages attributable
to his breach of the restrictive covenant and all profit, remuneration, or other
consideration that O'Leary gains from breaching the restrictive covenant; and
(c) reimbursement from O'Leary of all costs incurred by the Company and every
other member of the Consolidated Group in enforcing the restrictive covenant or
otherwise defending or prosecuting any legal proceeding arising out of the
restrictive covenant.  The Company may exercise any of the foregoing remedies
concurrently, independently, or successively.


                                       5

<PAGE>

     In the event any provisions hereof shall be modified or held ineffective by
any Court in any respect, such adjudication shall not invalidate or render
ineffective the balance of the provisions hereof, and the provisions hereof
shall be enforced to the maximum extent allowed by law.  This Agreement shall be
governed by the laws of the State of Texas and shall be enforceable in Harris
County, Texas. The Company may assign this Agreement (including the restrictive
covenants set forth in Sections IV and V) to anyone who succeeds to the
Company's business pursuant to a merger or purchase of all or substantially all
of the Company's assets. The members of the Consolidated Group are third-party
beneficiaries of O'Leary's obligations under Sections IV and V, and those
obligations are enforceable by them to the same extent as if they were parties
to this Agreement.


                                   SECTION VII


                                   TERMINATION

     The consulting arrangement hereunder shall be terminated upon the
occurrence of the first to occur of any of the following events: (1) the
expiration of the term of this Agreement; or (2) O'Leary's death, or such
physical or mental disability or incapacity of O'Leary which in the reasonable
opinion of the Company causes O'Leary to be unable to effectively perform his
duties under this Agreement for a continuous period of ninety (90) days, in
either of which events all unaccrued compensation due O'Leary by the Company
shall cease; or (3) written notice of termination of this Agreement with Cause
(as hereinafter defined) by the Company, given to O'Leary at any time and
effective as stated in such notice, in which event all unaccrued compensation
payable pursuant to the terms hereof shall cease upon such termination; or (4)
upon mutual agreement of parties hereto in writing.

     Termination for "Cause" is defined as termination for any of following
reasons: (1) if O'Leary has performed any of his duties under this Agreement in
a grossly negligent manner, breached any material provision of this Agreement,
or violated any statutory or common law duty of loyalty to the Company; (2) if
O'Leary has engaged in malfeasance, theft from the Company, embezzlement or is
convicted of a felony; or (3) if O'Leary has engaged in dishonesty, fraud or
willful disloyalty with respect to the assets or business of the Company or
matters affecting the consulting relationship established under this Agreement.
Upon termination of this Agreement by the Company or a termination of O'Leary's
consulting services for Cause by the Company, all future compensation to which
O'Leary would otherwise be entitled shall cease and terminate as of the date of
termination.
