         THE WARRANT REPRESENTED HEREBY AND THE SECURITIES ISSUABLE UPON

                                ACR GROUP, INC.

               WARRANT FOR THE PURCHASE OF SHARES OF COMMON STOCK

         No. 4                                                   750,000 Shares

         BY THIS WARRANT (this "Warrant"), ACR Group, Inc., a Texas corporation
(the "Company"), certifies that, for good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, The Catalyst Fund,
Ltd., a Texas limited partnership (along with its registered assigns, the
"Holder"), is entitled to subscribe for and purchase from the Company, subject
to the terms and conditions set forth herein, at any time on or after the date
hereof but prior to 5:00 p.m. (Houston, Texas time) on August 26, 2001, unless
otherwise extended as provided herein, or, if such date is not a business day,
the next succeeding business day (the "Exercise Period"), 750,000 (subject to
adjustment as set forth herein) fully paid and nonassessable shares (the
"Shares") of the Company's Common Stock, $.01 par value per share (the "Common
Stock"), at a price equal to the exercise price per share, initially $.58594
(subject to adjustment as set forth herein) per share (the "Exercise Price").

         1.       EXERCISE OF WARRANT; COMPANY OFFICE. This Warrant may be
exercised at any time or from time to time during the Exercise Period as to the
entire number or any lesser number of whole Shares, by the surrender of this
Warrant to the Company at its office at 3200 Wilcrest, #440, Houston, Texas
77042 or such other place as is designated in writing by the Company pursuant
to this Section 1, together with (a) a duly executed election in substantially
the form of Exhibit A attached hereto and made a part hereof for all purposes
and (b) a wire transfer or a certified or bank cashier's check payable to the
order of the Company in an amount equal to the Exercise Price multiplied by the
number of Shares of Common Stock covered by such election. For so long as this
Warrant is outstanding, the Company shall continue to maintain an office in the
State of Texas where notices, presentations and demands in respect of this
Warrant may be made upon it and shall notify the Holder in writing at least 15
days before changing the location of any such office.



   2
         2.      STOCK OWNERSHIP; STOCK CERTIFICATES; PARTIAL EXERCISE. Upon
each exercise of this Warrant, the Holder shall be deemed to be the holder of
record of the Shares of Common Stock issuable upon such exercise,
notwithstanding that the stock transfer books of the Company shall then be
closed or certificates representing such Shares shall not then have been
actually delivered to the Holder. As soon as possible after each such exercise
of this Warrant, the Company shall issue and deliver to the Holder a
certificate or certificates for the Shares issuable upon such exercise issued
in such denominations as may be specified by the Holder and registered in the
name of the Holder or, subject to Section 9, such other name or names as shall
be designated in the Holder's election to exercise. If this Warrant should be
exercised in part only, the Company shall, upon surrender of this Warrant for
cancellation, execute and deliver a new Warrant evidencing the right of the
Holder to purchase the balance of the Shares subject to purchase hereunder on
the terms and conditions set forth herein (including all changes and
adjustments that have occurred hereunder). The Company will, at the time of
each exercise of this Warrant, upon the request of the Holder hereof,
acknowledge in writing its continuing obligation to afford to the Holder all
rights to which the Holder shall continue to be entitled after such 
exercise in accordance with the terms of this Warrant; provided, however, 
that if the Holder of this Warrant shall fail to make any such request, 
such failure shall not affect the continuing obligation of the Company to 
afford such rights to the Holder.

         3.      COMPANY RECORDS; TRANSFEROR ASSIGNMENT OF WARRANT. Exchange of
Warrant. Any warrants issued in connection herewith or in substitution herefor,
upon complete or partial transfer, assignment or exercise (the "Warrants")
shall be numbered and shall be registered in the warrant register of the
Company (the "Warrant Register") as they are issued. The Company shall treat
the registered holder of any Warrant on the Warrant Register as the owner in
fact thereof for all purposes, except that if the Warrant is properly
transferred or assigned and notice of such transfer or assignment is given to
the Company, the Company shall treat the transferee or assignee as the owner
thereof for all purposes (or, if such transfer or assignment is properly made
in blank, the Company shall treat the bearer of this Warrant as the owner
thereof for all purposes). Should the Holder enter into a written agreement to
sell this Warrant to any Person, the Company shall have a right of first
refusal to purchase this Warrant from the Holder upon the same terms and
conditions set forth in such agreement. Such right of first refusal must be
exercised (by written notice to the Holder), and the purchase of this Warrant
must be consummated, if at all, within 45 days of receiving notice of the
Holder entering into such agreement. If such 45 day period expires without the
exercise of such right and the purchase of this Warrant by the Company, the
Holder shall be free to sell this Warrant to such Person without any liability
whatsoever to the Company. Upon exercise of such right of first refusal or the
expiration of such 45 day period without the Company exercising, such right of
first refusal, the Warrant shall be transferred by the Company upon delivery
thereof duly endorsed by the Holder or by his duly authorized attorney or
representative, or accompanied by proper evidence of succession, assignment or
authority to transfer. In case of transfer by executors, administrators,
guardians or other legal representatives, duly authenticated evidence of their
authority shall be produced if requested by the Company in its reasonable
discretion. The Company shall immediately register all assignments and
transfers in the Warrant Register, and, upon any registration of assignment or
transfer, the Company shall deliver a new





                                       2
   3
Warrant or Warrants to the person or entity entitled thereto on the terms and
conditions set forth herein (including all changes and adjustments that have
occurred hereunder). A Warrant, if properly transferred or assigned, may be
exercised by a subsequent Holder without having a new Warrant issued. The
Warrants may be exchanged at the option of the Holder thereof for another
Warrant, or other Warrants, of different denominations and representing in the
aggregate the right to purchase the same number of Shares of Common Stock on
the terms and conditions set forth herein (including all changes and
adjustments that have occurred hereunder) upon surrender to the Company or its
duly authorized agent. All provisions of this Section 3 shall be subject to
Section 13.

         4.      RESERVED STOCK. The Company shall reserve and keep available at
all times solely for the purpose of providing for the exercise of this Warrant
the maximum number of Shares of Common Stock as to which this Warrant may then
be exercised. All such Shares shall be duly authorized and free of preemptive
rights and, when issued upon such exercise, shall be validly issued and fully
paid and non-assessable with no liability on the part of the holders thereof.

         5.      CERTAIN ADJUSTMENTS.

                 (a)      Number of Shares; Exercise Price. The number of
         Shares of Common Stock which the Holder of this Warrant shall be
         entitled to receive upon each exercise hereof shall be determined by
         multiplying the number of Shares of Common Stock which would otherwise
         (but for the provisions of this Section 5) be issuable upon such
         exercise, as designated by the Holder hereof, by a fraction of which
         (i) the numerator is $.58594 and (ii) the denominator is the Exercise
         Price in effect on the date of such exercise. The Exercise Price shall
         be adjusted and readjusted from time to time as provided in this
         Section 5 and, as so adjusted or readjusted, shall remain in effect
         until a further adjustment or readjustment thereof is required by this
         Section 5.

                 (b)      Issuance of Additional Shares of Common Stock or
         Certain Convertible Securities. If the Company shall issue any Common
         Stock other than Excluded Stock (as hereinafter defined) without
         consideration or for a consideration per share less than the fair
         market value price per share of Common Stock (as determined by the
         Board of Directors of the Company) in effect immediately prior to such
         issuance, the Exercise Price in effect immediately prior to each such
         issuance shall immediately (except as otherwise expressly provided
         below) be reduced to the price determined by multiplying the Exercise
         Price in effect immediately prior to such issuance by the quotient
         determined by dividing (1) the sum of (x) the product of the total
         number of shares of Common Stock outstanding immediately prior to such
         issuance multiplied by the fair market value per share of Common Stock
         (as determined by the Board of Directors of the Company) in effect
         immediately prior to such issuance, and (y) the product of the total
         number of shares of Common Stock issued pursuant to such issuance
         multiplied by the consideration per share of Common Stock received
         under such issuance by (2) the number of shares of Common Stock
         outstanding immediately after such issuance multiplied by the fair
         market value price per share of Common Stock (as determined by the
         Board of Directors of the Company) in effect immediately prior to such
         issuance





                                       3
   4
         For the purposes of any adjustment of the Exercise Price pursuant to
this Section 5(b), the following provisions shall be applicable:

                          (A)     Cash. In the case of the issuance of Common
                 Stock for cash, the amount of the consideration received by
                 the Company shall be deemed to be the amount of the cash
                 proceeds received by the Company for such Common Stock after
                 deducting therefrom any discounts, commissions, taxes or other
                 expenses allowed, paid or incurred by the Company for any
                 underwriting or otherwise in connection with the issuance and
                 sale thereof

                          (B)     Consideration Other Than Cash. In the case of
                 the issuance of Common Stock (otherwise than upon the
                 conversion of shares of capital stock or other securities of
                 the Company) for a consideration in whole or in part other
                 than cash, including securities acquired in exchange therefor
                 (other than securities of the Company that by their terms are
                 exchangeable for such Common Stock), the consideration other
                 than cash shall be deemed to be the fair value thereof as
                 determined in good faith by the Board of Directors of the
                 Company and irrespective of any accounting treatment;
                 provided, that such fair value as determined by the Board of
                 Directors shall not exceed the aggregate Current Market Price
                 (as hereinafter defined) of the shares of Common Stock being
                 issued as of the date on which the Board of Directors
                 authorizes the issuance of such shares.

                          (C)     Options and Convertible Securities. In the
                 case of the issuance of (i) options, warrants or other rights
                 to purchase or acquire Common Stock (whether or not at the
                 time exercisable), (ii) securities by their terms convertible
                 into or exchangeable for Common Stock (whether or not at the
                 time so convertible or exchangeable), or (iii) options,
                 warrants or rights to purchase such convertible or
                 exchangeable securities (whether or not at the time
                 exercisable) other than Excluded Stock:

                                  (1)      the aggregate maximum number of
                          shares of Common Stock deliverable upon exercise of
                          such options, warrants or other rights to purchase or
                          acquire Common Stock shall be deemed to have been
                          issued at the time such options, warrants or rights
                          were issued and for a consideration equal to the
                          consideration (determined in the manner provided in
                          subclauses (A) and (B) above), if any, received by
                          the Company upon the issuance of such options,
                          warrants or rights plus the minimum purchase price
                          provided in such options, warrants or rights for the





                                       4
   5
                          Common Stock covered thereby;

                                  (2)      the aggregate maximum number of
                          shares of Common Stock deliverable upon conversion of
                          or in exchange for any such convertible or
                          exchangeable securities, or upon the exercise of
                          options, warrants or other rights to purchase or
                          acquire such convertible or exchangeable securities
                          and the subsequent conversion or exchange thereof,
                          shall be deemed to have been issued at the time such
                          securities were issued or such options, warrants, or
                          rights were issued and for a consideration equal to
                          the consideration, if any, received by the Company
                          for any such securities and related options, warrants
                          or rights (excluding any cash received on account of
                          accrued interest or accrued dividends), plus the
                          additional consideration (determined in the manner
                          provided in subclauses (A) and (B) above), if any, to
                          be received by the Company upon the conversion or
                          exchange of such securities, or upon the exercise of
                          any related options, warrants or rights to purchase
                          or acquire such convertible or exchangeable
                          securities and the subsequent conversion or exchange
                          thereof,

                                  (3)      on any change in the number of
                          shares of Common Stock deliverable upon exercise of
                          any such options, warrants or rights or conversion or
                          exchange of such convertible or exchangeable
                          securities or any change in the consideration to be
                          received by the Company upon such exercise,
                          conversion or exchange, including, but not limited
                          to, a change resulting from the anti-dilution
                          provisions thereof, the Exercise Price as then in
                          effect shall forthwith be readjusted to such Exercise
                          Price as would have been obtained had an adjustment
                          been made upon the issuance of such options, warrants
                          or rights not exercised prior to such change, or of
                          such convertible or exchangeable securities not
                          converted or exchanged prior to such change, upon the
                          basis of such change;

                                  (4)      on the expiration or cancellation of
                          any such options, warrants or rights or the
                          termination of the right to convert or exchange such
                          convertible or





                                       5
   6
                          exchangeable securities, if the Exercise Price shall
                          have been adjusted upon the issuance thereof, the
                          Exercise Price shall forthwith be readjusted to such
                          Exercise Price as would have been obtained had an
                          adjustment been made upon the issuance of such
                          options, warrants, rights or such convertible or
                          exchangeable securities on the basis of the issuance
                          of only the number of shares of Common Stock actually
                          issued upon the exercise of such options, warrants or
                          rights, or upon the conversion or exchange of such
                          convertible or exchangeable securities; and

                                  (5)      if the Exercise Price shall have
                          been adjusted upon the issuance of any such options,
                          warrants, rights or convertible or exchangeable
                          securities, no further adjustment of the Exercise
                          Price shall be made for the actual issuance of Common
                          Stock upon the exercise, conversion or exchange
                          thereof

                          (D)     Excluded Stock. "Excluded Stock" shall mean
                 (1) up to 200,000 shares of Common Stock to be issued from
                 time to time to directors, officers, employees, consultants,
                 advisors, independent contractors and agents of the Company
                 pursuant to stock options, employee benefit plans or otherwise
                 together with any such shares that are repurchased by the
                 Company and reissued to any such recipient, (2) shares of

                 issued to Alex Trevino, Jr. pursuant to that certain
                 employment agreement entered into between the Company and Alex
                 Trevino, Jr. dated as of May 17, 1993, (5) up to 500,000

                 warrants Issued by the Company to St. James Capital Partners,
                 L.P., a Delaware limited partnership ("St. James"), or its
                 assigns, and (7) shares of Common Stock to be issued to St.
                 James, or its assigns, pursuant to private placement purchases

                 Company which are convertible into Common Stock, in an
                 aggregate amount not to exceed $5,000,000. All shares of
                 Excluded Stock that the Company has reserved for issuance
                 shall be deemed to be outstanding for all purposes of
                 computations under this Section 5(b).

                 (c) Stock Dividends, Subdivisions, Reclassifications or 
                 Combinations.





                                       6
   7
         If the Company shall (i) declare a dividend or make a distribution on
         its Common Stock in shares of its Common Stock, (ii) subdivide or
         reclassify the outstanding shares of Common Stock into a greater
         number of shares, or (iii) combine or reclassify the outstanding
         Common Stock into a smaller number of shares, the Exercise Price in
         effect at the time of the record date for such dividend or 
         distribution or the effective date of such subdivision, combination or
         reclassification shall be proportionately adjusted so that the Holder
         of this Warrant who exercises this Warrant after such date shall be
         entitled to receive the number of shares of Common Stock which he
         would have owned or been entitled to receive had this Warrant been
         exercised immediately prior to such date. Successive adjustments in
         the Exercise Price shall be made whenever any event specified above
         shall occur.

                 (d)      Other Distributions. In case the Company shall fix a
         record date for the making of a distribution to all holders of shares
         of its Common Stock (i) of shares of any class other than its Common
         Stock or (ii) of evidence of indebtedness of the Company or any
         subsidiary or (iii) of assets (excluding cash dividends or
         distributions, and dividends or distributions referred to in Section
         5(c) above) or (iv) of rights or warrants (excluding those referred to
         in Section 5(b)), in each case the Exercise Price in effect
         immediately prior thereto shall be multiplied by the &action
         determined by dividing (A) an amount equal to the difference
         resulting Tom (x) fair market value price per share of Common Stock on
         such record date, less (y) the fair market value (as determined by the
         Board of Directors, whose determination shall be conclusive) of said
         shares or evidences of indebtedness or assets or rights or warrants to
         be so distributed divided by the number of shares of Common Stock
         outstanding on such record date, by (B) the fair market value price
         per share of Common Stock on such record date. Such adjustment shall
         be made successively whenever such a record date is fixed. In the
         event that such distribution is not so made, the Exercise Price then
         in effect shall be readjusted, effective as of the date when the Board
         of Directors determines not to distribute such shares, evidence of
         indebtedness, assets, rights or warrants, as the case may be, to the
         Exercise Price which would then be in effect if such record date had
         not been fixed.

                 (e)      Other Dilutive Events. In case any event shall occur
         as to which the provisions of this Section 5 are not strictly
         applicable but the failure to make any adjustment relating thereto
         would not fairly protect the purchase rights represented by this
         Warrant in accordance with the essential intent and principles of this
         Section 5, then, in each such case, the Company shall immediately
         make all adjustments necessary to preserve, without dilution, the
         purchase rights represented by this Warrant on a basis consistent with
         the intent and principles established in this Section 5 and shall also
         immediately appoint a firm of independent certified public accountants
         of recognized national standing (which may be the regular auditors of
         the Company if they satisfy such standard), which shall give their
         opinion that such adjustment, if any, preserves, without dilution, the
         purchase rights represented by this Warrant on a basis consistent with
         the intent and principles established in this Section 5. Upon receipt
         of such opinion, the Company will immediately deliver a copy thereof
         to the Holder of this Warrant. The Company shall not, by amendment of





                                       7
   8
         its certificate of incorporation or through any consolidation, merger,
         reorganization, transfer of assets, dissolution, issue or sale of
         securities or any other voluntary avoid or seek to avoid the
         observance or performance of any of the terms of this Warrant, and
         will at all times in good faith assist in carrying out all of such
         terms and in the taking of all such actions as may be necessary or
         appropriate in order to protect the rights of the Holder of this
         Warrant against dilution or other impairment. Without limiting the
         generality of the foregoing, the Company (i) will not permit the par
         value of any shares of stock receivable upon the exercise of this
         Warrant to exceed the amount payable therefor upon such exercise, (ii)
         will take all such action as may be necessary or appropriate in order
         that the Company may validly and legally issue fully paid and
         nonassessable shares of stock on the exercise of the Warrants from
         time to time outstanding, and (iii) will not take any action that
         results in any adjustment of the Exercise Price if the total number of
         Shares of Common Stock issuable after such action upon the exercise of
         all of the Warrants would exceed the total number of Shares of Common
         Stock then authorized by the Company's certificate of incorporation
         and available for the purpose of issuance upon such exercise.

                 (f)      Size of Adjustment; Rounding. No adjustment in the
         Exercise Price shall be required unless such adjustment would require
         an increase or decrease of at least one cent ($.01) in such price;
         provided, however, that any adjustment that is thereby not required to
         be made shall be carried forward and taken into account in any
         subsequent adjustment. All calculations under this Section 5 shall be
         made to the nearest cent or to the nearest one-hundredth of a Share,
         as the case may be.

                 (g)      Notice. Whenever there shall be an adjustment as
         provided in this Section 5, the Company shall within three (3) days
         cause written notice thereof to be given to the Holder, which notice
         shall be accompanied by an officer's certificate setting forth the
         Exercise Price after such adjustment and setting forth a brief
         statement of the facts requiring such adjustment and the computation
         thereof. However, the failure by the Company to satisfy its
         obligations under this Section 5(g) shall not in any manner affect or
         alter the rights of the Holder under this Warrant.

                 (h)      Fractional Shares. The Company shall not be required
         to issue fractions of shares of Common Stock or other capital stock of
         the Company upon the exercise of Warrants. If any fraction of a share
         would be issuable upon the exercise of any Warrant (or specified
         portions thereof), the Company shall purchase such fraction for an
         amount in cash equal to the same fraction of the fair value of such
         share of Common Stock (as determined in good faith by the Board of
         Directors of the Company but not less than the fair market value) on
         the date of exercise of the Warrant.

                 (i)      Current Market Price. The Current Market Price at any
         date shall mean, in the event the Common Stock is publicly traded, the
         average of the daily closing prices per share of Common Stock for 30
         consecutive trading days ending no more than 5 trading days before
         such date (as adjusted for any stock dividend, split,
        




                                       8
   9
         combination or reclassification that took effect during such 30
         trading day period), as determined by the Board of Directors of the
         Company. The closing price for each day shall be the last reported
         sale price regular way or, in case no such reported sale takes place
         on such day, the average of the last closing bid and asked prices
         regular way, in either case on the principal national securities
         exchange on which the Common Stock is listed or admitted to trading,
         or if not listed or admitted to trading on any national securities
         exchange, the closing sale price for such day reported by NASDAQ, if
         the Common Stock is traded over-the-counter and quoted in the National
         Market System, or if the Common Stock is so traded, but not so quoted,
         the average of the closing reported bid and asked prices of the Common
         Stock as reported by NASDAQ or any comparable system or, if the Common
         Stock is not listed on NASDAQ or any comparable system, the average of
         the closing bid and asked prices as furnished by two members of the
         National Association of Securities Dealers, Inc. selected from time to
         time by the Company for that purpose. If the Common Stock is not
         traded in such manner that the quotations referred to above are
         available for the period required hereunder, the Current Market Price
         per share of Common Stock shall be deemed to be the fair value as
         determined by the Board of Directors of the Company in good faith and
         irrespective of any accounting treatment.

                 (j)      Treasury Stock. For the purposes of this Section 5,
         the sale or other disposition of any Common Stock theretofore held in
         the Company's treasury shall be deemed to be an issue thereof

                 (k) Valid Issuance. All shares of Common Stock which may be
         issued upon the exercise of this Warrant will upon issuance by the
         Company be duly and validly issued, fully paid and nonassessable and
         free from all taxes, liens and charges with respect to the issuance
         thereof, and the Company shall take no action which will cause a
         contrary result (including, without limitation, any action which would
         cause the Exercise Price to be less than the par value, if any, of the
         Common Stock).

         6.      PREEMPTIVE RIGHTS. If the Company shall issue any Shares of
Common Stock, rights, options, or warrants to purchase Shares of Common Stock,
or securities of any type whatsoever that are, or may become, convertible into
Shares of Common Stock (collectively, "New Securities," which term shall
exclude any Excluded Stock), the Holder of this Warrant shall be entitled to
purchase its pro rata share of all or any part of such New Securities as
provided in this Section 6. For purposes of this Section 6, the term "pro rata
share" shall mean such share as would be necessary to permit the Holder to
maintain a percentage interest in the Company (determined on a fully diluted
basis assuming the exercise of any and all outstanding options or warrants and
the conversion of any securities convertible into Shares of Common Stock) equal
to the Holder's percentage interest in the Company immediately prior to such
issuance of New Securities (determined on a fully diluted basis). In the event
the Company proposes to undertake an issuance of New Securities, it shall give
the Holder written notice of its intention, describing the type of New
Securities and the price and terms upon which the Company proposes to issue the
same. The Holder shall have 30 days from the date of receipt of any such notice
to agree to purchase up to its pro rata share of such New Securities for the
price and upon the terms specified in the notice by giving written notice to
the Company and stating therein the quantity of New Securities to be purchased.
In the event





                                       9
   10
the Holder fails to exercise such right of purchase within said 30-day period,
the Company shall have 90 days thereafter to complete the sale of the New
Securities at the price and upon terms no more favorable to the purchasers of
such New Securities than those specified in the Company's notice to the Holder.
In the event the Company has not sold the New Securities within such 90-day
period, the Company shall not thereafter issue or sell any of such New
Securities without first complying with the terms of this Section 6.

         7.      PUT OPTIONS.

                 (a)      Option based on Purchase Offer for Assets. The
         Company shall notify the Holder promptly, and in any event within five
         days of receipt, of any bona fide written offer received by the
         Company for the purchase of all or substantially all of the Company's
         assets or its stock (each an "Offer"). Should the Company determine
         that an Offer is unacceptable, the Holder shall have the option to
         require the Company to purchase this Warrant and/or the Shares of
         Common Stock issued pursuant hereto (or any portion thereof) at a
         price determined by multiplying (i) the total consideration offered
         for the Company's assets or stock, as applicable, under such Offer,
         multiplied by, if such Offer is for less than all of the Company's
         assets or stock, as applicable, a &action, the numerator of which is
         the market value of all of the Company's assets or stock, as
         applicable, as determined by the board of directors of the Company,
         which number shall in no event be less than the total consideration
         offered under the Offer, and the denominator of which is the total
         consideration offered under the Offer, by (ii) the percentage
         ownership of the Common Stock of the Company represented by this
         Warrant and the Shares of Common Stock issued pursuant hereto that the
         Holder wishes to require the Company to purchase under this Section
         7(a) (expressed as a decimal and calculated on a fully diluted basis).
         The price to be paid to the Holder shall be reduced if the Holder has
         elected to require the Company to purchase any unissued Shares of
         Common Stock evidenced by this Warrant by an amount equal to (iii) the
         Exercise Price then in effect, multiplied by (iv) the number of
         unissued Shares of Common Stock evidenced by this Warrant that the
         Holder has elected to require the Company to purchase. Unless
         otherwise agreed to in writing by the Holder, the required purchase
         price shall be payable in cash within 60 days of the Company's receipt
         of notice of the Holder's election to require the Company to purchase
         this Warrant and/or the Shares of Common Stock issued pursuant hereto
         (or any portion thereof) under this Section 7(a). If at any time the
         Company has not paid the required purchase price after the Holder has
         exercised its option under this Section 7(a), the Holder, in addition
         to having the right to enforce the payment of such required purchase
         price, shall also have the right, if the Company shall after the
         receipt of such first Offer receive a later Offer that the Holder
         deems more favorable than such first Offer, to rescind its election
         under the first Offer and require the Company to purchase this Warrant
         and/or the Shares of Common Stock issued pursuant hereto (or any
         portion thereof) under the terms of such later Offer in accordance
         with the terms and procedures set forth above. This option shall be a
         continuing option, exercisable as many times as the Holder shall
         choose, and shall continue and remain until the Holder has sold all
         unissued Shares of Common Stock evidenced by this Warrant and all
         Shares of Common Stock issued





                                       10
   11
         hereunder to the Company.

                 (b)      General Option. At any time after the period
         beginning on May 26, 1996, upon 90 days prior written notice to the
         Company (such notice being herein referred to as the "Put Notice"),
         provided the Company's stock is no longer publicly traded, the Holder
         shall have the option to require the Company to purchase this Warrant
         and/or the Shares of Common Stock issued pursuant hereto (or any
         portion thereof) for a price equal to the product of (i) the
         percentage ownership of the Common Stock of the Company represented by
         this Warrant and the Shares of Common Stock issued pursuant hereto
         that the Holder wishes to require the Company to purchase under this
         Section 7(b) (expressed as a decimal and calculated on a fully diluted
         basis), and (ii) the greater of the following values, all calculated
         as of the last day of the month immediately preceding the date the Put
         Notice is delivered to the Company (A) 150% of the net book value of
         the Company, (B) 400% of the earnings before interest, taxes,
         depreciation and amortization (less any outstanding funded debt to The
         Catalyst Fund, Ltd. and other lenders) ("EBITDA") of the Company for
         the preceding 24 month period ended on the last day of the month
         immediately preceding, the date the Put Notice is delivered to the
         Company, or (C) at the option of the Holder, the appraised value of
         the Company. The appraised value of the Company shall be determined as
         of the last day of the month immediately preceding the date the Put
         Notice is delivered to the Company in the following manner: First,
         the Holder shall select and pay for an appraisal of the Company
         performed by a certified appraiser (the "First Appraisal"). The
         appraised value of the Company as determined by the First Appraisal
         shall be binding upon the Company and the Holder as the appraised
         value of the Company unless the Company shall notify the Holder in
         writing of its objection to such appraised value within 30 days of the
         Company's receipt of notice of such appraised value (the "First
         Appraisal Notice"). If the Company so notifies the Holder, the
         appraised value of the Company determined by the First Appraisal shall
         nevertheless remain the appraised value of the Company unless the
         Company shall pay for and obtain a second appraisal of the Company
         from a certified appraiser (the "Second Appraisal") and deliver such
         Second Appraisal to the Holder within 30 days of receipt of the First
         Appraisal Notice. If the Company complies with the requirements of the
         preceding sentence, the Second Appraisal shall be binding upon the
         Company and the Holder as the appraised value of the Company unless
         the Holder shall notify the Company of its objection to such Second
         Appraisal within 30 days of the Holder's receipt of the Second
         Appraisal. If the Holder so notifies the Company, the Company and the
         Holder shall appoint a third certified appraiser to determine the value
         of the company, and if the Company and the Holder cannot reach an
         agreement as to such third certified appraiser, the Company and the
         Holder shall appoint a third party to appoint a third certified
         appraiser, which determination of appraiser shall be binding upon the
         Company and the Holder. The appraisal determined by such third
         appraiser (the "Third Appraisals) shall be binding upon the Company
         and the Holder and shall be the appraised value of the Company.  The
         Company and the Holder shall bear equally all costs of such Third
         Appraisal. The price to be paid to the Holder shall be reduced if the
         Holder has elected to require the Company to purchase any unissued
         Shares of Common Stock evidenced by this





                                       11
   12
         Warrant by an amount equal to (iii) the Exercise Price then in
         effect, multiplied by (iv) the number of unissued Shares of Common
         Stock evidenced by this Warrant that the Holder has elected to require
         the Company to purchase. Unless otherwise agreed to in writing by the
         Holder, the required purchase price shall be payable in cash within 75
         days of the Company's receipt of notice of the Holder's election to
         require the Company to purchase unissued Shares of Common Stock
         evidenced by this Warrant and/or Shares of Common Stock issued
         pursuant hereto (or any portion thereof) under this Section 7(b). This
         option shall be a continuing option, exercisable as many times as the
         Holder shall choose, and shall continue and remain until the Holder
         has sold all unissued Shares of Common Stock evidenced by this Warrant
         and all Shares of Common Stock issued hereunder to the Company.

                 (c)      Purchase by Third Party. At the option of the board
         of directors of the Company, the Company may allow all, or any portion
         greater than 25 percent, of the Warrant or any Common Stock required
         to be purchased by the Company pursuant to Section 7(a) or 7(b) above,
         to be purchased directly by any of the Company's shareholders
         provided, however, that should any of the Company's shareholders fail
         to make payment of the required purchase price on the designated
         purchase date, the Company shall be required to purchase such portion
         of this Warrant or such Common Stock intended to be purchased by such
         shareholders of the Company.

         8. CERTAIN CORPORATE EVENTS OR ACTIONS.

                 (a)      Consolidation, Merger, Etc. In case of any
         consolidation with or merger of the Company with or into another
         corporation or other entity (except for a merger or consolidation in
         which the Company is the continuing corporation other than as a
         subsidiary of another corporation or other entity), or in case of any
         sale, lease or conveyance to another corporation or other entity of
         the property of the Company as an entirety or substantially as an
         entirety, such successor, purchasing, leasing or receiving corporation
         or other entity, as the case may be, shall, prior to and as a
         condition to the occurrence of such event, (i) execute with the Holder
         an agreement providing that the Holder shall have the right thereafter
         to receive upon exercise of this Warrant the kind and amount of shares
         of stock and other securities, property, cash or any combination
         thereof receivable upon such consolidation, merger, sale, lease or
         conveyance by a holder of the number of Shares of Common Stock for
         which this Warrant might have been exercised immediately prior to such
         consolidation, merger, sale, lease or conveyance and (ii) make
         effective provision in its certificate of incorporation or otherwise,
         if needed, in order to effect such agreement. Such agreement shall
         provide for adjustments which shall be equivalent to the adjustments
         in Section 5.

                 (b)      Reclassification, Etc. In case of any
         reclassification or change of the Shares of Common Stock issuable upon
         exercise of this Warrant or in case of any consolidation or merger of
         another corporation or other entity with or into the Company in which
         the Company is the continuing corporation (other than as a subsidiary
         of another corporation or other entity) and in which there is a





                                       12
   13
         reclassification or change (including a change to the right to receive
         cash or other property) of the Shares of Common Stock, the Holder
         shall have the right thereafter to receive upon exercise of this
         Warrant the kind and amount of shares of stock and other securities,
         property, cash or any combination thereof receivable upon such
         reclassification, change, consolidation or merger by a holder of the
         number of Shares of Common Stock into which this Warrant would have
         been exercisable immediately prior to such reclassification, change,
         consolidation or merger. Thereafter, appropriate provision (as
         determined by the Board of Directors of the Company in good faith)
         shall be made for adjustments which shall be equivalent to the
         adjustments in Section 5.

         9.      CERTAIN RESTRICTIONS. Notwithstanding the adjustment
provisions contained in this Warrant, the Company shall not take any of the
following actions without first receiving the express written consent of the
Holder:

                 (a)      Except for the issuance of up to 550,000 shares of
Common Stock which may be issued to Alex Trevino, Jr. pursuant to that certain
employment agreement entered into between the Company and Alex Trevino, Jr.
dated as of May 17, 1993, issue Common Stock (otherwise than upon the
conversion of shares of capital stock or other securities of the Company) for a
consideration in whole or in part other than cash, including securities
acquired in exchange therefor (other than securities of the Company that by
their terms are exchangeable for such Common Stock).

                 (b)      Make a distribution to all holders of shares of its
Common Stock of (i) shares of any class other than its Common Stock, (ii)
evidence of indebtedness of the Company or any subsidiary, or (iii) assets
(excluding cash dividends or distributions, and dividends or distributions
referred to in Section 5(c)), or (iv) of rights or warrants (excluding those
referred to in Section 5(b).

                 (c)      Enter into any consolidation with or merger with or
into another corporation or other entity (except for a merger or consolidation
in which the Company is the continuing corporation other than as a subsidiary
of another corporation or other entity), or enter into any sale, lease or
conveyance to another corporation or other entity of the property of the
Company as an entirety or substantially as an entirety.

         10.     EXTENSION OF EXPIRATION DATE. If the last scheduled payment
date for the repayment of outstanding indebtedness under any of those certain
promissory notes (the "Notes"), dated April 14, 1997 executed by West Coast
HVAC Supply, Inc., a Texas corporation, in the aggregate original principal
amount of $450,000 and the others of which are each dated May 26, 1993 executed
by ACR Supply, Inc., a Texas corporation, Fabricated Systems, Inc., a Texas
corporation, and Heating and Cooling Supply, Inc., a Nevada corporation, and
payable to the order of The Catalyst Fund, Ltd., a Texas limited partnership,
in the aggregate original principal amount of $1,000,000 shall be extended
beyond August 26, 2001, then the expiration date of this Warrant shall also be
likewise extended to the date that is equal to the latest of the last scheduled
