Item 2.  Acquisition or Disposition of Assets.

         On September 9, 1997, ACR Group, Inc. ("the Company") through its
wholly-owned subsidiary, Contractors Heating & Supply, Inc., a Texas
corporation ("CHS"), acquired certain of the assets, and assumed certain of the
liabilities, of Contractors Heating and Supply Company, a Colorado corporation
(the "Seller").  The Seller's business was the wholesale distribution of
heating, ventilation, air conditioning and refrigeration ("HVACR") products.
CHS acquired substantially all of the Seller's assets that were used in its
operations, except for certain real estate occupied by the Seller's branch
locations (the "Facilities").  CHS assumed substantially all of the Seller's
liabilities, except for mortgage indebtedness relating to the Facilities.  CHS
will lease the Facilities from the Seller for three years, with an option to
extend such lease for an additional three years and an option to purchase the
Facilities for $3,000,000 at any time during the initial three-year lease term.

         CHS paid to the Seller $4,626,315 cash at closing, and issued a
promissory note ("Note") to the Seller for $1,200,000.  In addition, CHS
assumed $1,200,000 of indebtedness of the Seller to certain of its
shareholders, which was paid in full at closing by CHS.

         All of the cash paid to the Seller at closing came from available
funds under the Company's revolving line of credit with NationsBank of Texas,
N.A., which was increased from $8 million to $18 million in August 1997.

         The Note bears interest at 8 1/2% per annum.  The Note is to be repaid
in three annual principal installments of $400,000 each, plus accrued interest,
beginning September 1, 1998, and is secured by a first lien on certain
machinery and equipment purchased by CHS from the Seller that is used to
fabricate sheet metal products.  The Note is subordinated to the Company's
senior secured indebtedness to NationsBank of Texas, N.A.

         The acquired assets are all used in connection with its business of
fabricating sheet metal products and distributing such sheet metal and other
HVACR products purchased for resale.  CHS intends to continue using the
acquired assets for such purpose.

         CHS and Daryl G. Brady, President and a shareholder of the Seller,
entered into a Consulting Agreement for a period of one year.  The Consulting
Agreement also restricts Mr. Brady from competing with CHS for a period of
three years following its expiration.

Item 7.  Financial Statements, Pro Forma Financial Information and Exhibits.

financial statements of the Seller or the 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 November 24, 1997.

         (a)     At Closing, the amount of the Purchase Price, less $1,200,000,
                 less the Earnest Money, as hereafter defined shall be paid by
                 certified check or wire transfer to the Company.

         (b)     At Closing, the Purchaser shall issue to the Company a
                 promissory note in the original principal amount of $1,200,000
                 (the "Note") such Note to be substantially in the form
                 attached hereto and incorporated herein as Exhibit D.

                 (i)      The Note shall be secured by a first lien on the

                          and incorporated herein as Exhibit E.

                 (ii)     The payment of the Note shall be guaranteed by ACRG,
                          such guaranty to be evidenced by a guaranty agreement
                          ("Guaranty Agreement") substantially in the form

                 (iii)    Payments in respect of the Note shall be subordinated
                          as to payment to indebtedness of ACRG (and the
                          Purchaser, as a guarantor of such indebtedness) to
                          its secured lender, NationsBank of Texas, N.A.
                          ("Senior Lender") as evidenced by a subordination
                          agreement ("Subordination Agreement") to be
                          substantially in the form attached hereto and
                          incorporated herein as Exhibit G.

                 (iv)     A breach or default under the Note shall be deemed to
                          be a breach or default under the Lease and a breach
                          or default under the Lease shall be a default under
                          the Note, as set forth more particularly in the
                          provisions of the Note and the Lease.

         The Subchapter S Distribution Notes shall be paid in full by the
Purchaser at Closing.

         The Purchase Price shall be and hereby is allocated among the
respective Assets in the manner set forth on Exhibit H attached hereto.  The
parties hereto shall take no position with respect to such allocation which is
inconsistent therewith.

         1.5     DISCLAIMER OF LIABILITIES.  With the exception of the Assumed
Liabilities specifically set forth in Exhibit B, the Purchaser shall not assume
or be responsible for any claims against or liabilities or obligations
whatsoever of the Company,  and the Company will at all times indemnify and
hold the Purchaser harmless from and against any claim therefor or liability
arising therefrom.  The Purchaser shall have no liability for any income,
franchise or other tax or charge, if any, which may become payable by the
Company or the Shareholders in connection with the Company's sale of the Assets
pursuant to this Agreement or any other income taxes or charges arising out of
the operation of the Company's business at any time prior to the Closing Date,
and all such taxes shall be duly and timely paid by the Company.
Notwithstanding any other provisions to the contrary in this Agreement, the
Purchaser and ACRG shall take all action necessary so that the Company, the
Shareholders, and the directors and officers of the Company shall be released,
to the extent practicable, from all personal guaranties executed by any of them
as to liabilities, contractual commitments or indebtedness of the Company which
are assumed by the Purchaser hereunder.

         1.6     INSTRUMENTS OF TRANSFER.  The Company will deliver to the
Purchaser at the Closing (in addition to the other documents provided for in
this Agreement) such bills of sale, endorsements, assignments and other good
and sufficient instruments of conveyance, transfer and assignment, in customary
form and substance, as shall be effective to vest in the Purchaser good and
marketable title to the Assets and to lease the Leased Premises to the
Purchaser.

         1.7     FURTHER ASSURANCES.  From time to time after the Closing, at
the Purchaser's request but without further consideration, the Company will
execute and deliver such other instruments of conveyance and transfer and take
such other action as the Purchaser reasonably may require more effectively to
vest title to the Assets in the Purchaser and to assign the Glenwood Property
Lease to the Purchaser.

         1.8     EARNEST MONEY.  The Purchaser has previously paid the Company
an earnest money deposit of $125,000.  Upon execution of this Agreement, the
Purchaser shall pay to the Company $125,000 as additional earnest money
(together, the "Earnest Money") which will be applied, at Closing, in partial
payment of the Purchase Price.  The parties agree that the Earnest Money shall
be non-refundable unless the failure to close the contemplated transaction is
due to the failure of a condition precedent to the Purchaser's obligation to
close the transaction contemplated herein.

         1.9     CLOSING.  The closing of the transaction provided for herein
(the "Closing") shall take place at a date, time and location specified by the
Purchaser, but not later than September 9, 1997.  The date of the Closing is
referred to in this Agreement as the "Closing Date".  If the Closing does not
occur on or before September 9, 1997 without a breach of any representation,
warranty, covenant, or condition precedent by any party hereto, then this
Agreement shall terminate without liability of either party to the other and
the Earnest Money shall be immediately paid to the Company.

         1.10    SALES AND USE TAX.  Purchaser shall be responsible for the
timely payment of all sales, use and other transfer taxes resulting from the
sale of the Assets to the Purchaser.

                       REPRESENTATIONS AND WARRANTIES OF
                        THE COMPANY AND THE SHAREHOLDERS

         The Company and the Shareholders each, jointly and severally,
represent and warrant to the Purchaser as follows:

         2.1     ORGANIZATION, EXISTENCE AND GOOD STANDING. The Company is a
corporation duly organized, validly existing and in good standing under the
laws of the State of Colorado and has all requisite corporate power and
authority to own or lease and operate its properties and to carry on its
business as now being conducted.  The Company is duly qualified or licensed and
in good standing to do business in each jurisdiction in which the property
owned or leased and operated by it or the nature of the business conducted by
it make such qualification or licensing necessary.

         2.2     AUTHORITY.  The Company has full corporate power and authority
to execute and deliver this Agreement and to consummate the transactions
contemplated hereby.  The execution and delivery of this Agreement and the
consummation of the transactions contemplated hereby have been duly and validly
authorized and approved by the Company's board of directors and the
Shareholders, and no corporate proceedings on the part of the Company are
necessary to authorize this Agreement or the consummation of the execution and
delivery of this Agreement by the Company and the consummation of the
transactions contemplated hereby.  This Agreement has been duly and validly
executed and delivered by the Company, and this





                                       4
<PAGE>   9
Agreement constitutes the legal, valid and binding agreement of the Company and
the Shareholders enforceable in accordance with its terms.

         2.3     CONSENTS AND APPROVALS; NO VIOLATION.  No filing or
registration with, and no permit, authorization, consent or approval of, any
public body or authority is necessary for the consummation of the transactions
contemplated by this Agreement.  Neither the execution and delivery of this
Agreement, the consummation of the transactions contemplated hereby, nor the
compliance by the Company with any of the provisions hereof will, as of the
Closing Date, (a) conflict with or result in any breach of any provision of the
Articles of Incorporation or Bylaws of the Company, (b) subject to the
Purchaser or the Company, whichever may be applicable in the circumstances
(with the cooperation of the other, if necessary) obtaining any required
consents, result in a violation or breach of, or constitute (with or without
due notice or lapse of time or both) a default (or give rise to any right of
termination, cancellation or acceleration) under, any of the terms, conditions
or provisions of any note, contract, agreement, commitment, bond, mortgage,
indenture, license, lease, pledge agreement or other instrument or obligation
to which the Company is a party or by which the Company or any of its
properties or assets may be bound, (c) give rise to any lien, charge or other
encumbrance on any of the Assets or the Leased Premises, or (d) violate any
law, regulation, judgment, order, writ, injunction or decree applicable to the
Company or any of the Assets.

         2.4     FINANCIAL STATEMENTS.   The Company and the Shareholders have
previously furnished to ACRG and the Purchaser the balance sheets of the
Company as of December 25, 1995, December 25, 1996 and August 25, 1997 (the
"Current Balance Sheet Date") (collectively, the "Balance Sheets" and, as to
the Balance Sheet dated August 25, 1997, the "Current Balance Sheet"), and
combined income statements ("Income Statements") for the two (2) years ended
December 25, 1995 and December 25, 1996 and the eight (8) month period ended

referred to herein as the "Financial Statements").  The Balance Sheets fairly
present in all material respects the financial position of the Company as of
the date thereof and the Income Statements fairly present the results of
operations of the Company for the periods set forth therein.  The Financial
Statements have been prepared in accordance with generally accepted accounting
principles consistently applied by the Company during the periods involved,
subject, in the case of interim statements, to customary year end adjustments.

         2.5     RECEIVABLES.  The accounts receivable of the Company shown on
the Current Balance Sheet arose from sales of inventory by the Company in the
ordinary course of business and constitute valid and binding obligations of the
respective account obligors; provided, however, neither the Company nor the
Shareholders makes any representation or warranty regarding the collectibility
of the accounts receivable.

         2.6     INVENTORIES.  The inventories of the Company shown on the
Current Balance Sheet consist of items of a quantity and a quality usable or
salable in the normal course of the business of the Company and the values at
which such inventories are carried reflect the normal inventory valuation
policy of the Company stating the inventories at the lower of cost or market





                                       5

applicable to the Company or any tax liabilities due or to become due and
whether incurred in respect or measured by the income or sales of the Company
for any period prior to the close of business on the Current Balance Sheet
Date, or arising out of any transaction entered into, or any state of facts
existing, prior thereto.

         2.8     ABSENCE OF CHANGES.  Except as set forth on Schedule 2.8,
since the Current Balance Sheet Date, there has not been (a) any change in the

destruction or loss, whether covered by insurance or not, materially and
adversely affecting the properties and business of the Company; (c) any sale,

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 known to the Company, 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 the Company (whether
or not covered by insurance).

         2.9     AGREEMENTS, CONTRACTS AND COMMITMENTS.  Except as set forth on
Schedule 2.9, (a) the Company is not a party to and is not bound by any

or credit agreement, security agreement, guaranty, indenture,mortgage, pledge,
conditional sale or title retention agreement, equipment obligation, lease

of the parties thereto, enforceable in accordance with its terms; (c) to the
best of the Company's knowledge, the Company has not

breached any material provision of, and is not 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

agreement or commitment; (d) to the best of the Company's knowledge, no other
party to any such material contract, agreement or commitment to which the
Company is a party or by which the Company is bound is in default thereunder or

tax returns, tax reports and unemployment insurance contribution reports
required to be filed by the Company prior to the date hereof are true, correct

                 judgment, writ, order, injunction or decree applicable to the
                 Company or any of the Assets.

                          (iv)  To such counsel's knowledge, except as

                 legal, administrative, arbitration, investigatory or other
                 proceedings, and no other controversies which might have a
                 material adverse effect on the condition (financial or
                 otherwise) or operations of the Company, pending or
                 threatened, against the Company or as to which the Company is
                 a party, or challenging the validity or propriety of the

                 the same period of the prior year; provided, however, that no
                 material adverse change to the Company shall be deemed to have

         5.4     COVENANT OF GOOD FAITH.  The Company and the Purchaser agree
to use reasonable diligence and to exert their best, good faith efforts to
satisfy the conditions precedent set forth in this Article V.

                                   ARTICLE VI

                                INDEMNIFICATION

         6.1     INDEMNIFICATION BY THE COMPANY AND THE SHAREHOLDERS. The
Company and the Shareholders  shall, jointly and severally, indemnify and hold
the Purchaser and ACRG 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 the Purchaser or ACRG, directly or indirectly, from (a) any
inaccurate representation or warranty by or on behalf of the Company or the
Shareholders in or pursuant to the provisions of this Agreement, (b) the breach
or default in the performance by the Company or the Shareholders of any of the
obligations to be performed by or on behalf of the Company or the Shareholders,
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 the Purchaser and ACRG 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 the Company or the Shareholders which has not been assumed by the
Purchaser hereunder, or (d) any breach or default in the performance of any
obligation to be performed by or on behalf of the Company or the Shareholders
before the Closing Date, which results in a claim being asserted against the
Purchaser or ACRG.  The Company and the Shareholders shall, in addition,
reimburse the Purchaser and ACRG on demand for any payment made by the
Purchaser or ACRG 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 the Purchaser or ACRG which, if successful, might result in
a breach or default by the Company or the Shareholders, then the Purchaser or
ACRG shall give prompt written notice thereof to the Company and the
Shareholders and the Company and the Shareholders shall be entitled to elect,
within ten (10) days after the giving of such notice, to participate in the
defense thereof and to be represented, at the sole expense of the Company and
the Shareholders, by counsel selected by the Company and the Shareholders.  The
Purchaser and/or ACRG shall not compromise or settle any such claim without
giving the Company and the Shareholders ten (10) days written notice thereof if
the effect of any such compromise or settlement would require indemnification
by the Company and the Shareholders for all or any part of the amount of such
compromise or settlement, and receipt of the express written consent of the
Company and the Shareholders to such compromise or settlement, which consent
shall not be unreasonably delayed or withheld.

         6.2     INDEMNIFICATION BY THE PURCHASER AND ACRG.  The Purchaser and
ACRG shall indemnify and hold the Company and the Shareholders 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 the Company or the Shareholders
from (a) any inaccurate representation by or on behalf of the Purchaser or ACRG
in or pursuant to the provisions of this Agreement, (b) the breach or default
in the performance by the Purchaser or ACRG of any of the obligations to be
performed by or on behalf of the Purchaser or ACRG hereunder (unless such
breach or default in the performance occurred on or before the Closing Date and
this Agreement was terminated because of such breach or default in the
performance, in which case the Company and the Shareholders shall be deemed to
have waived any rights under this Section 6.2 to indemnification for Damages
caused by such breach or default in the performance) or (c) any breach or
default by the Purchaser or ACRG in the performance of any obligation to be
performed by the Purchaser or ACRG after the Closing Date, which results in a
claim being asserted against the Company or the Shareholders.  The Purchaser
shall, in addition, reimburse the Company and the Shareholders on demand for
any payment made by the Company and the Shareholders 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 the
Company and the Shareholders, if successful, might result in a breach or
default by the Purchaser or ACRG, then the Company and the Shareholders shall
give prompt written notice thereof to the Purchaser and ACRG, and the Purchaser
shall be entitled to elect, within ten (10) days after the giving of such
notice, to participate in the defense thereof and to be represented, at the
sole expense of the Purchaser and ACRG, by counsel to be selected by the
Purchaser and ACRG.  Neither the Company nor the Shareholders shall compromise
or settle any such claim without giving the Purchaser and ACRG ten (10) days
written notice thereof if the effect of any such compromise or settlement would
require indemnification by the Purchaser and ACRG for all or any part of the
amount of such compromise or settlement and receipt of the express written
consent of the Purchaser and ACRG to such compromise or settlement, which
consent shall not be unreasonably delayed or withheld.

         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, and no
claim shall be made under either Section 6.1 or Section 6.2 (except with
respect to the Purchaser's failure to pay or perform an Assumed Liability)
until the aggregate Damages from all claims to date thereunder shall exceed
$25,000.

writing, in accordance with the provisions of Section 8.4 hereof.

         7.3     EFFECT OF TERMINATION OR WAIVER.  In the event that this

indemnification, made by the parties and contained in this Agreement shall
survive the Closing for a period of two (2) years and all inspections,

obligation, covenant, agreement or condition herein may be waived by the
Company or the Purchaser, 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

consistent with the requirements for a waiver of compliance as set forth in
this Section 8.3.

shall be binding upon and inure to the benefit of the parties hereto and their
respective successors and permitted assigns, but neither this Agreement nor any
of the rights, interests or obligations hereunder shall be assigned by any of
the parties hereto without the prior written consent of the other parties;
provided, however, that the Purchaser may, without the prior written consent of
the Company, assign its rights, interests and obligations hereunder to a
corporation controlling or under common control with the Purchaser, but the
Purchaser shall not be relieved from liability hereunder.  This Agreement is
not intended to and shall not confer upon any person other than the parties any
rights or remedies hereunder.

         8.6     GOVERNING LAW.  This Agreement shall be governed by the laws
of the State of Colorado (regardless of the laws that might otherwise govern
under applicable Colorado principles of conflicts of law) as to all matters,
including but not limited to matters of validity, construction, effect,
performance and remedies.

         8.7     JURISDICTION AND VENUE.  Any process against the Purchaser or
ACRG or the Company or the Shareholders in, or in connection with, any suit,
action or proceeding arising out of or relating to this Agreement or any of the
transactions contemplated by this Agreement may be served personally or by
certified mail at the address set forth in Section 8.4 with the same effect as
though served on it or him personally.

         8.8     COUNTERPARTS.  This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

         8.9     INTERPRETATION.  The article and section headings contained in
this Agreement are solely for the purpose of reference, are not part of the
agreement of the parties and shall not in any way affect the meaning or
interpretation of this Agreement.

         8.10    ENTIRE AGREEMENT.  This Agreement, including the exhibits
hereto and the documents, instruments and schedules referred to herein,
embodies the entire agreement and understanding of the parties hereto in
respect of the subject matter contained herein.  There are no restrictions,

terminate and the Purchaser will hire all of the Company's employees; provided,
however, that nothing contained herein shall be deemed to create an agreement

employee in its sole discretion.  In connection therewith, the Purchaser will
continue all of the Company's benefit plans (except the Company's 401(k) plan)

Monthly Deposits exceed the actual taxes and assessments, the excess amount
shall, at Landlord's option, except as may be otherwise provided by law, either

Deposits.  In the event of a transfer by Tenant of Tenant's interest in the
Demised Premises, Landlord shall be entitled to return the Monthly Deposits to
Tenant's successor in interest and Landlord shall thereupon be discharged from
any further liability with respect to the Monthly Deposits.

deemed the only property of Landlord.

shall have the right to contest any Taxes and Assessments; provided that no
protest of Taxes and Assessments shall reduce the amount of the Monthly
Deposits required to be paid by Tenant hereunder unless and until such protest

reduction or recovery of any Taxes and Assessments attributable to the Lease
Term less all costs and expenses incurred by Landlord, including attorneys'
fees, in connection with such abatement, reduction or recovery.

not be disturbed in its possession of the Demised Premises provided only that
Tenant shall attorn to the party acquiring title to the Demised Premises as the
result of such foreclosure.  No act or further agreement by Tenant shall be
necessary to establish the subordination of this Lease to any such mortgage or
deed of trust but Tenant covenants and agrees, upon request of Landlord, to
execute such documents as may be necessary or appropriate to confirm and
establish this Lease as subordinate to any such mortgage or





                                      -7-
<PAGE>   40
deed of trust in accordance with the foregoing provisions.  Alternatively,
Tenant covenants and agrees that, at Landlord's option, Tenant shall execute
documents as may be necessary to establish this Lease and Tenant's interest in
the Demised Premises as superior to any such mortgage or deed of trust.  If
Tenant fails to execute any documents required to be executed by Tenant under
the provisions hereof, Tenant hereby makes, constitutes  and irrevocably
appoints Landlord as Tenant's attorney in fact and in Tenant's name, place and
stead to execute any such documents.

                 7.17      No Assignment or Subletting.  Tenant covenants and
agrees not to make or permit a Transfer by Tenant, as hereinafter defined,
without Landlord's prior written consent, which consent shall not be
unreasonably withheld.  A Transfer by Tenant shall include an assignment of
this Lease, a sublease of all or any part of the Demised Premises or any
assignment, sublease, transfer, mortgage, pledge or encumbrance of all or any
part of Tenant's interest under this Lease or in the Demised Premises, by
operation of law or otherwise, or the use or occupancy of all or any part of
the Demised Premises by anyone other than Tenant.  Any such Transfer by Tenant
without Landlord's written consent shall be void and shall constitute a default
under this Lease.  In the event Landlord consents to any Transfer by Tenant,
Landlord shall be entitled to receive fifty percent (50%) of all consideration
to be paid by the assignee, sublessee or transferee for the use and enjoyment
of Tenant's rights under this Lease in excess of the amounts payable by Tenant
hereunder (whether such consideration is paid in a lump-sum, by multiple
payments, or as additional rent or rent premiums, or otherwise), and Tenant
shall not be relieved of its obligations under this Lease and Tenant shall
remain liable, jointly and severally and as a principal, and not as a guarantor
or surety, under this Lease, to the same extent as though no Transfer by Tenant
had been made, unless specifically provided to the contrary in Landlord's prior
written consent.  The acceptance of rent by Landlord from any person other than
Tenant shall not be deemed to be a waiver by Landlord of the provisions of this
Section or of any other provision of this Lease and any consent by Landlord to
Transfer by Tenant shall not be deemed a consent to any subsequent Transfer by
Tenant.  In the event Landlord consents to a Transfer by Tenant, any right
which may at the time have been granted to Tenant to extend the Lease Term
shall automatically terminate and be of no further force or effect unless
otherwise agreed to by Landlord in writing.  Tenant covenants and agrees to pay
to Landlord, within 10 days after demand by Landlord, the reasonable costs and
expenses of Landlord in connection with any request by Tenant for consent to a
Transfer by Tenant, including reasonable attorneys' fees, whether or not
consent of Landlord is given to the Transfer by Tenant.

                 7.18      Annual Financial Statements.  Tenant covenants and
agrees to furnish to Landlord annually, within 90 days after the end of each
fiscal year of Tenant, copies of financial statements of Tenant audited, if
requested by Landlord, by a certified public accountant, and agrees that
Landlord may deliver any such financial statements to any existing or
prospective mortgagee or purchaser of the Demised Premises.  The financial
statements shall include a balance sheet as of the end of, and a statement of
profit and loss for, the preceding fiscal year of Tenant and, if regularly
prepared by Tenant, a statement of sources and use of funds for the preceding
fiscal year of Tenant.

                 7.19      Payment of Income and Other Taxes.  Tenant covenants
and agrees to pay promptly when due all personal property taxes on personal
property of Tenant on the Demised Premises and all federal, state and local
income taxes, sales taxes, use taxes, Social Security taxes, unemployment taxes
and taxes withheld from wages or salaries paid to Tenant's employees, the
nonpayment of which might give rise to a lien on the Demised Premises or
Tenant's interest therein, and to furnish, if requested by Landlord, evidence
of such payments.

                 7.20      Estoppel Certificates.  Tenant covenants and agrees
to  execute, acknowledge and deliver to Landlord, upon Landlord's written
request, a written statement certifying that this Lease is unmodified (or, if
modified, stating the modifications) and in full force and effect; stating the
dates to





                                      -8-
<PAGE>   41
which Basic Rent has been paid; stating the amount of Monthly Deposits held by
Landlord for the then tax year; and stating whether or not Landlord is in
default under this Lease (and, if so, specifying the nature of the default).
Tenant agrees that such statement may be delivered to and relied upon by any
existing or prospective mortgagee or purchaser of the Demised Premises.  Tenant
agrees that a failure to deliver such a statement within 10 days after written
request from Landlord shall be conclusive upon Tenant that this Lease is in
full force and effect without modification except as may be represented by
Landlord; that there are no uncured defaults by Landlord under this Lease; and
that any representation by Landlord with respect to Basic Rent and Monthly
Deposits are true.

                 7.21      Landlord Right to Inspect and Show Premises and to
Install "For Sale" Signs.  Tenant covenants and agrees that Landlord and the
authorized representatives of Landlord shall have the right to enter the
Demised Premises at any reasonable time during ordinary business hours for the
purposes of inspecting, repairing or maintaining the same or performing any
obligations of Tenant which Tenant has failed to perform hereunder or for the
purposes of showing the Demised Premises to any existing or prospective
mortgagee, purchaser or lessee of the Demised Premises.  Tenant covenants and
agrees that Landlord may at any time and from time to time place on the Demised
Premises a sign advertising the Demised Premises for sale or for lease
(provided that a for lease sign may be placed on the premises only during the
last 120 days of the Term or following a default by Tenant).

                 7.22      Landlord Title to Fixtures, Improvements and
Equipment.  Tenant covenants and agrees that all fixtures and improvements on
the Demised Premises and including all plumbing, heating, lighting, electrical
and air conditioning fixtures and equipment, whether or not attached to or
affixed to the Demised Premises, and whether now or hereafter located upon the
Demised Premises, shall be and remain the property of the Landlord upon
expiration of the Lease Term.

                 7.23      Removal of Tenant's Equipment.  Tenant covenants and
agrees to remove, at or prior to the expiration of the Lease Term, all of
Tenant's Equipment, as hereinafter defined.  "Tenant's Equipment" shall mean
all equipment, apparatus, machinery, signs, furniture, furnishings and personal
property used in the operation of the business of Tenant (as distinguished from
the use and operation of the Demised Premises).  If such removal shall injure
or damage the Demised Premises Tenant covenants and agrees, at its sole cost
and expense, at or prior to the expiration of the Lease Term, to repair such
injury and damage in good and workmanlike fashion and to place the Demised
Premises in the same condition as the Demised Premises would have been if such
Tenant's Equipment had not been installed.  If Tenant fails to remove any
Tenant's Equipment by the expiration of the Lease Term, Landlord may, at its
option, keep and retain any such Tenant's Equipment or dispose of the same and
retain any proceeds therefrom, and Landlord shall be entitled to recover from
Tenant any costs or expenses of Landlord in removing the same and in restoring
the Demised Premises in excess of the actual proceeds, if any, received by
Landlord from disposition thereof.

                 7.24      Tenant Indemnification of Landlord.  Tenant
covenants and agrees to protect, indemnify and save Landlord harmless from and
against all liability, obligations, claims, damages, penalties, causes of
action, costs and  expenses, including attorneys' fees, imposed upon, incurred
by or asserted against Landlord by reason of (a) any accident, injury to or
death of any person or loss of or damage to any property occurring on or about
the Demised Premises; (b) any act or omission of Tenant or Tenant's officers,
employees, agents, guests or invitees or of anyone claiming by, through or
under Tenant; (c) any use which may be made of, or condition existing upon, the
Demised Premises; (d) any improvements, fixtures or equipment upon the Demised
Premises; (e) any failure on the part of Tenant to perform or comply with any
of the provisions, covenants or agreements of Tenant contained in this Lease;
(f) any violation of any law, ordinance, order, rule or regulation of
governmental authorities having jurisdiction by Tenant or Tenant's officers,
employees, agents, guests or invitees or by anyone





                                      -9-
<PAGE>   42
claiming by, through or under Tenant; and (g) any repairs, maintenance or
Changes to the Demised Premises by, through or under Tenant.  Tenant further
covenants and agrees that, in case any action, suit or proceeding is brought
against Landlord by reason of any of the foregoing, Tenant will, at Tenant's
sole cost and expense, defend Landlord in any such action, suit or proceeding.

                 7.25      Waiver by Tenant.  Tenant waives and releases any
claims Tenant may have against Landlord or Landlord's officers, agents or
employees for loss, damage or injury to person or property sustained by Tenant
or Tenant's officers, agents, employees, guests, invitees or anyone claiming
by, through or under Tenant resulting from any cause whatsoever other than
gross negligence or willful misconduct.

                 7.26      Release upon Transfer by Landlord.  In the event of
a transfer by Landlord of the Demised Premises or of Landlord's interest as
Landlord under this Lease, Landlord's successor or assign shall take subject to
and be bound by this Lease and, in such event, Tenant covenants and agrees that
Landlord shall be released from all obligations of Landlord under this Lease,
except obligations which arose and matured prior to such transfer by Landlord;
that Tenant shall thereafter look solely to Landlord's successor or assign for
satisfaction of the obligations of Landlord under this Lease; and that, upon
demand by Landlord or Landlord's successor or assign, Tenant shall attorn to
such successor or assign.
                          VIII.  DAMAGE OR DESTRUCTION

                 8.1       Tenant's Notice of Damage.  For the purposes of this
Article VIII and Article IX each location listed on Exhibit A (a "Location")
constituting a portion of the Demised Premises will be treated separately and
the portion of Basic Rent allocable to each Location shall be as set forth on
Exhibit A.  If any portion of a Location shall be damaged or destroyed by fire
or other casualty, Tenant shall give prompt written notice thereof to Landlord
("Tenant's Notice of Damage").

                 8.2       Options to Terminate if Damage Substantial.  Upon
receipt of Tenant's Notice of Damage, Landlord shall promptly proceed to
determine the nature and extent of the damage or destruction and to estimate
the time necessary to repair or restore the Location.  As soon as reasonably
possible, Landlord shall give written notice to Tenant stating Landlord's
estimate of the time necessary to repair or restore the Location ("Landlord's
Notice of Repair Time").  If Landlord reasonably estimates that repair or
restoration of the Location cannot be completed within 180 days from the time
of Tenant's Notice of Damage, Landlord and Tenant shall each have the option to
terminate this Lease with respect to that Location.  In the event, however,
that the damage or destruction was caused by the act or omission of Tenant or
Tenant's officers, employees, agents, guests or invitees or of anyone claiming
by, through or under Tenant, Landlord shall have the option to terminate this
Lease with respect to the Location if Landlord reasonably estimates that the
repair or restoration cannot reasonably be completed within the time period
specified above, but Tenant shall not have the option to terminate this Lease
with respect to the Location.  Any option granted hereunder shall be exercised
by written notice to the other party given within 10 days after Landlord's
Notice of Repair Time.  In the event either Landlord or Tenant exercises its
option to terminate this Lease with respect to a Location, the Lease Term with
respect to that Location shall expire 10 days after the notice by either
Landlord or Tenant exercising such party's option to terminate this Lease with
respect to that Location.  In the event of termination of this Lease with
respect to a Location under the provisions hereof, Landlord shall refund to
Tenant such amounts of Basic Rent and Additional Rent theretofore paid by
Tenant with respect to that Location as may be applicable to the period
subsequent to the time of Tenant's Notice of Damage less the reasonable value
of any use or occupation of the Location by Tenant subsequent to the time of
Tenant's Notice of Damage.





                                      -10-
<PAGE>   43
                 8.3       Obligations to Repair and Restore.  In the event
repair and restoration of Location can be completed within the period specified
in Section 8.2, in Landlord's reasonable estimation or this Lease is not
terminated with respect to the Location as provided therein, this Lease shall
continue in full force and effect and Landlord with respect to the Location,
subject to receipt of adequate insurance proceeds therefor and the payment by
Tenant of any uninsured costs as specified in Section 8.4, shall proceed
forthwith to cause the Location to be repaired and restored with reasonable
diligence and there shall be abatement of Basic Rent with respect to the
Location to the extent Landlord receives the proceeds of rental loss insurance
maintained pursuant to Section 5.1 proportionate to the extent of the space and
period of time that Tenant is unable to use and enjoy the Location.  Landlord
may, at its option, require Tenant to arrange for and handle the repair and
restoration of the Location, in which case Landlord shall furnish Tenant with
funds for such repair and restoration at the time or times such funds are
needed, to the extent of any proceeds from insurance to cover the costs of
repair or restoration.

                 8.4       Application of Insurance Proceeds.  The proceeds of
any Casualty Insurance maintained on a Location, other than casualty insurance
maintained by Tenant on fixtures and personal property of Tenant, shall be paid
to and become the property of Landlord, subject to any obligation of Landlord
to cause the Location to be repaired and restored.  If the proceeds of
insurance are not sufficient to repair or restore the Location, Tenant shall
pay when due the uninsured costs of repair or restoration.


                               IX.  CONDEMNATION

                 9.1       Taking -- Substantial Taking -- Insubstantial
Taking.  A "Taking" shall mean the taking of all or any portion of a Location
as a result of the exercise of the power of eminent domain or condemnation for
public or quasi-public use or the sale of all or part of the Demised Premises
under the threat of condemnation.  A "Substantial Taking" shall mean a Taking
of so much of the Location that the Location cannot thereafter be reasonably
used by Tenant for carrying on, at substantially the same level or scope, the
business theretofore conducted by Tenant on the Location.  An "Insubstantial
Taking" shall mean a Taking such that the Location can thereafter continue to
be used by Tenant for carrying on, at substantially the same level or scope,
the business theretofore conducted by Tenant on the Location.

                 9.2       Termination on Substantial Taking.  If there is a
Substantial Taking with respect to a Location, the Lease Term with respect to
the Location shall expire on the date of vesting of title pursuant to such
Taking.  In the event of termination of this Lease with respect to the Location
under the provisions hereof, Landlord shall refund to Tenant such amounts of
Basic Rent and Additional Rent theretofore paid by Tenant as may be applicable
to the Location for the period subsequent to the time of termination of this
Lease with respect thereto.

                 9.3       Restoration on Insubstantial Taking.  In the event
of an Insubstantial Taking, this Lease with respect to the Location shall
continue in full force and effect, and there shall be an abatement of Basic
Rent proportionate to the extent of the space so taken.  Landlord may, at its
option, require Tenant to arrange for and handle any restoration of the
Location, in which case Landlord shall furnish Tenant with funds for such
restoration at the time or times such funds are needed, to the extent of the
proceeds of any awards or consideration received as a result of the Taking to
cover the costs of restoration.

                 9.4       Right to Award.  The total award, compensation,
damages or consideration received or receivable as a result of a Taking
("Award") shall be paid to and be the property of Landlord, whether the Award
shall be made as compensation for diminution of the value of the leasehold or
the fee of the Location or otherwise and Tenant hereby assigns to Landlord, all
of Tenant's right, title and





                                      -11-
<PAGE>   44
interest in and to any such Award.  Tenant covenants and agrees to execute,
immediately upon demand by Landlord, such documents as may be necessary to
facilitate collection by Landlord of any such Award.  Without limiting the
foregoing, Tenant shall have the right to claim and recover from the condemning
authority, but not from Landlord, such compensation as may be recoverable by
Tenant on account of any and all damage to Tenant's business by reason of the
Taking or for or on account of any of Tenant's moving expenses, to the extent
that such compensation does not reduce the Award to which Landlord is entitled.

                             X.  DEFAULTS BY TENANT

                 10.1      Defaults Generally.  Each of the following shall
constitute a "Default by Tenant" under this Lease:

                 10.2      Failure to Pay Rent or Other Amounts.  A Default by
Tenant shall exist if Tenant fails to pay when due, Basic Rent, Additional
Rent, Monthly Deposits, or any other amounts payable by Tenant under the terms
of this Lease, and such failure shall continue for 5 days after written notice
from Landlord to Tenant of such failure, provided however, that Tenant shall
not be entitled to more than two notices of such failure during any lease year
and if, after two such notices are given in any lease year, Tenant fails,
during such lease year, to pay any such amounts when due, such failure shall
constitute a Default by Tenant without further notice by Landlord.

                 10.3      Violation of Lease Terms.  A Default by Tenant shall
exist if Tenant breaches or fails to comply with any agreement, term, covenant
or condition in this Lease applicable to Tenant (other than as specified in
Section 10.2), and such breach or failure to comply continues for a period of
20 days after notice thereof by Landlord to Tenant, or, if such breach or
failure to comply cannot be reasonably cured within such 20-day period, if
Tenant shall not in good faith commence to cure such breach or failure to
comply within such 20-day period or shall not diligently proceed therewith to
completion.

                 10.4      Nonoccupancy of Demised Premises.  A Default by
Tenant shall exist if Tenant shall fail to occupy and use the Demised Premises
within 15 days after commencement of the Lease Term or shall leave the Demised
Premises unoccupied for 15 consecutive days or shall vacate and abandon the
Demised Premises.

                 10.5      Transfer of Interest Without Consent.  A Default by
Tenant shall exist if Tenant's interest under this Lease or in the Demised
Premises shall be transferred to or pass to or devolve upon any other party
without Landlord's prior written consent.

                 10.6      Execution and Attachment against Tenant.  A Default
by Tenant shall exist if Tenant's interest under this Lease or in the Demised
Premises shall be taken upon execution or by other process of law directed
against Tenant, or shall be subject to any attachment at the instance of any
creditor or claimant against Tenant and said attachment shall not be discharged
or disposed of within 15 days after the levy thereof.

                 10.7      Bankruptcy or Related Proceedings.  A Default by
Tenant shall exist if Tenant shall file a petition in bankruptcy or insolvency
or for reorganization or arrangement under the bankruptcy laws of the United
States or under any similar act of any state, or shall voluntarily take
advantage of any such law or act by answer or otherwise, or shall be dissolved
or shall make an assignment for the benefit of creditors or if involuntary
proceedings under any such bankruptcy or insolvency law or for the





                                      -12-
<PAGE>   45
dissolution of Tenant shall be instituted against Tenant or a receiver or
trustee shall be appointed for the Demised Premises or for all or substantially
all of the property of Tenant, and such proceedings shall not be dismissed or
such receivership or trusteeship vacated within 60 days after such institution
or appointment.

                 10.8      Default Related to Purchase Agreement.  A Default by
Tenant shall exist if Tenant is in default under the promissory note or
security agreement executed and delivered by Tenant to Landlord in connection
with the closing under the Purchase Agreement which is not cured within a cure
period specified therein.

                            XI.  LANDLORD'S REMEDIES

                 11.1      Remedies Generally.  Upon the occurrence of any
Default by Tenant, Landlord shall have the right, at Landlord's election, then
or at any time thereafter, to exercise any one or more of the following
remedies:

                 11.2      Cure by Landlord.  In the event of a Default by
Tenant, Landlord may, at Landlord's option, but without obligation to do so,
and without releasing Tenant from any obligations under this Lease, make any
payment or take any action as Landlord may deem necessary or desirable to cure
any such Default by Tenant in such manner and to such extent as Landlord may
deem necessary or desirable.  Landlord may do so without demand on, or written
notice to, Tenant and without giving Tenant an opportunity to cure such Default
by Tenant.  Tenant covenants and agrees to pay to Landlord, within 10 days
after demand, all advances, costs and expenses of Landlord in connection with
the making of any such payment or the taking of any such action, including
reasonable attorney's fees, together with interest as hereinafter provided,
from the date of payment of any such advances, costs and expenses by Landlord.
Action taken by Landlord may include commencing, appearing in, defending or
otherwise participating in any action or proceeding and paying, purchasing,
contesting or compromising any claim, right, encumbrance, charge or lien with
respect to the Demised Premises which Landlord, in its discretion, may deem
necessary or desirable to protect its interest in the Demised Premises and
under this Lease.

                 11.3      Termination of Lease and Damages.  In the event of a
Default by Tenant, Landlord may terminate this Lease, effective at such time as
may be specified by written notice to Tenant, and demand (and, if such demand
is  refused, recover) possession of the Demised Premises from Tenant.  Tenant
shall remain liable to Landlord for damages in an amount equal to the Basic
Rent, Additional Rent and other sums which would have been owing by Tenant
hereunder for the balance of the term, had this Lease not been terminated, less
the net proceeds, if any, of any reletting of the Demised Premises by Landlord
subsequent to such termination, after deducting all Landlord's reasonable
expenses in connection with such recovery of possession or reletting.  Landlord
shall be entitled to collect and receive such damages from Tenant on the days
on which the Basic Rent, Additional Rent and other amounts would have been
payable if this Lease had not been terminated.  Alternatively, at the option of
Landlord, Landlord shall be entitled to recover forthwith from Tenant, as
damages for loss of the bargain and not as a penalty, an aggregate sum which,
at the time of such termination of this Lease, represents the excess, if any,
of (a) the aggregate of the Basic Rent, Additional Rent and all other sums
payable by Tenant hereunder that would have accrued for the balance of the
Lease Term, over (b) the aggregate rental value of the Demised Premises for the
balance of the Lease Term, both discounted to present worth at the rate of 8%
per annum.





                                      -13-
<PAGE>   46
                 11.4      Repossession and Reletting.  In the event of Default
by Tenant, Landlord may reenter and take possession of the Demised Premises or
any part thereof, without demand or notice, and repossess the same and expel
Tenant and any party claiming by, under or through Tenant, and remove the
effects of both using such force for such purposes as may be necessary, without
being liable for prosecution on account thereof or being deemed guilty of any
manner of trespass, and without prejudice to any remedies for arrears of rent
or right to bring any proceeding for breach of covenants or conditions.  No
such reentry or taking possession of the Demised Premises by Landlord shall be
construed as an election by Landlord to terminate this Lease unless a written
notice of such intention is given to Tenant.  No notice from Landlord hereunder
or under a forcible entry and detainer statute or similar law shall constitute
an election by Landlord to terminate this Lease unless such notice specifically
so states.  Landlord reserves the right, following any reentry or reletting, to
exercise its right to terminate this Lease by giving Tenant such written
notice, in which event the Lease will terminate as specified in said notice.
After recovering possession of the Demised Premises, Landlord may, from time to
time, but shall not be obligated to, relet the Demised Premises, or any part
thereof, for the account of Tenant, for such term or terms and on such
conditions and upon such other terms as Landlord, in its uncontrolled
discretion, may determine.  Landlord may make such repairs, alterations or
improvements as Landlord may consider appropriate to accomplish such reletting,
and Tenant shall reimburse Landlord upon demand for all costs and expenses,
including attorneys' fees, which Landlord may incur in connection with such
reletting.  Landlord may collect and receive the rents for such reletting but
Landlord shall in no way be responsible or liable for any failure to relet the
Demised Premises, or any part thereof, or for any failure to collect any rent
due upon such reletting.  Notwithstanding Landlord's recovery of possession of
the Demised Premises, Tenant shall continue to pay on the dates herein
specified, the Basic Rent, Additional Rent and other amounts which would be
payable hereunder if such repossession had not occurred.  Upon the expiration
or earlier termination of this Lease, Landlord shall refund to Tenant any
amount, without interest, by which the amounts paid by Tenant, when added to
the net amount, if any, recovered by Landlord through any reletting of the
Demised Premises, exceeds the amounts payable by Tenant under this Lease.  If,
in connection with any reletting, the new lease term extends beyond the
existing term, or the premises covered thereby include other premises not part
of the Demised Premises, a fair apportionment of the rent received from such
reletting and the  expenses incurred in connection therewith will be made in
determining the net amount recovered from such reletting.

                 11.5      Suits by Landlord.  Actions or suits for the
recovery of amounts and damages payable under this Lease may be brought by
Landlord from time to time, at Landlord's election, and Landlord shall not be
required to await the date upon which the Lease Term would have expired to
bring any such action or suit.

                 11.6      Recovery of Landlord Enforcement Costs.  All costs
and expenses incurred by Landlord in connection with collecting any amounts and
damages owing by Tenant pursuant to the provisions of this Lease not paid by
Tenant when due or to enforce any provision of this Lease following a default
by Tenant, including reasonable attorneys' fees, whether or not any action is
commenced by Landlord, shall be paid by Tenant to Landlord upon demand.

                 11.7      Late Payment Penalty.  Tenant covenants and agrees
to pay to Landlord a late payment penalty in the amount of 10% per month of any
installment of Monthly Rent or Monthly Deposits that Tenant fails to pay when
due; provided that no such late payment penalty shall be due in the event
payment of such installment of Monthly Rent or Monthly Deposits is made by
Tenant within 5 days after written notice from Landlord to Tenant of Tenant's
failure to pay such amount when due.

                 11.8      Interest on Advances.  Tenant covenants and agrees
to pay to Landlord interest on demand at the rate of 2% above the "Prime Rate,"
as hereinafter defined, on the amount of any





                                      -14-
<PAGE>   47
payment made by Landlord required to have been made by Tenant under this Lease
and on the amount of any costs and expenses, including reasonable attorneys'
fees, paid by Landlord in connection with the taking of any action to cure any
Default by Tenant, from the date of making any such payment or the advancement
of such costs and expenses by Landlord.  "Prime Rate" shall mean the rate
announced by Colorado National Bank of Denver, a national banking association
(the "Bank"), or other bank as hereinafter provided, at the time of making any
such payment or the advancement of such costs and expenses by Landlord, as its
prime rate, but not in excess of the maximum amount of finance charge
permissible under applicable law.  In the event that the Bank discontinues the
use of a Prime Rate, the Prime Rate being announced by any other national
banking association located in Denver, Colorado, as selected by Landlord in its
sole discretion, shall be used for computing the interest rate under this
Section.

                 11.9      Landlord's Bankruptcy Remedies.  Nothing contained
in this Lease shall limit or prejudice the right of Landlord to prove and
obtain as liquidated damages in any bankruptcy, insolvency, receivership,
reorganization or dissolution proceeding, an amount equal to the maximum
allowable by any statute or rule of law governing such proceeding in effect at
the time when such damages are to be proved, whether or not such amount be
greater, equal or less than the  amounts recoverable, either as damages or
rent, under this Lease.

                 11.10     Remedies Cumulative.  Exercise of any of the
remedies of Landlord under this Lease shall not prevent the concurrent or
subsequent exercise of any other remedy provided for in this Lease or otherwise
available to Landlord at law or in equity.

                        XII.  SURRENDER AND HOLDING OVER

                 12.1      Surrender upon Lease Expiration.  Upon the
expiration or earlier termination of this Lease, or on the date specified in
any demand for possession by Landlord after any Default by Tenant, Tenant
covenants and agrees to surrender possession of the Demised Premises to
Landlord, in the same condition as when Tenant first occupied the Demised
Premises, ordinary wear and tear excepted.

                 12.2      Holding Over.  If Tenant shall hold over after the
expiration of the Lease Term, without written agreement providing otherwise,
Tenant shall be deemed to be a tenant from month to month, at a monthly rental,
payable in advance, equal to 150% of the Monthly Rental for the last month of
the Lease Term, and Tenant shall be bound by all of the other terms, covenants
and agreements of this Lease.  Nothing contained herein shall be construed to
give Tenant the right to hold over at any time, and Landlord may exercise any
and all remedies at law or in equity to recover possession of the Demised
Premises, as well as any damages incurred by Landlord, due to Tenant's failure
to vacate the Demised Premises and deliver possession to Landlord as herein
provided.

                              XIII.  MISCELLANEOUS

                 13.1      Guarantor.  Tenant's obligations under this Lease
are guaranteed by ACR Group, Inc. under the terms of a separate Guaranty as of
even date herewith.

                 13.2      No Implied Waiver.  No failure by Landlord to insist

this Lease, no failure by Landlord to exercise any right or remedy under this
Lease, and no acceptance of full or partial payment during the continuance of
any





                                      -15-
<PAGE>   48
Default by Tenant, shall constitute a waiver of any such term, covenant or
agreement, or a waiver of any such right or remedy, or a waiver of any such
Default by Tenant.

                 13.3      Survival of Provisions.  Notwithstanding any
termination of this Lease, the same shall continue in force and effect as to
any provisions hereof which require observance or performance by Landlord or
Tenant subsequent to termination.

                 13.4      Covenants Independent.  This Lease shall be
construed as if the covenants herein between Landlord and Tenant are
independent, and not dependent, and Tenant shall not be entitled to any offset
against Landlord if Landlord fails to perform its obligations under this Lease.

                 13.5      Covenants as Conditions.  Each provision of this
Lease performable by Tenant shall be deemed both a covenant and a condition.

                 13.6      Tenant's Remedies.  Tenant may bring a separate
action against Landlord for any claim Tenant may have against Landlord under
this Lease, provided Tenant shall first give written notice thereof to Landlord
and shall afford Landlord a reasonable opportunity to cure any such default.
In addition, Tenant shall send notice of such default by certified or
registered mail, postage prepaid, to the holder of any mortgage or deed of
trust covering the Demised Premises or any portion thereof of whose address
Tenant has been notified in writing, and shall afford such holder a reasonable
opportunity to cure any default on Landlord's behalf.  In no event will
Landlord be responsible for any damages incurred by Tenant, including, but not
limited to, loss of profits or interruption of business as a result of any
default by Landlord hereunder.

                 13.7      Binding Effect.  Without limiting the provisions of
Section 7.17, this Lease shall extend to and be binding upon the heirs,
executors, legal representatives, successors and assigns of the respective
parties hereto.

                 13.8      Short Form Lease.  This Lease shall not be recorded,
but the parties agree, at the request of either of them, to execute a short
form lease for recording, containing the names of the parties, a description of
the Demised Premises and the Lease Term.

                 13.9      Notices and Demands.  All notices, demands or
billings under this Lease shall be in writing, and shall be deemed properly
given and received when actually given and received or 3 business days after
mailing, if sent by registered or certified United States mail, postage
prepaid, addressed to the party to receive the notice at the address set forth
for such party in the first paragraph of this Lease or at such other address as
either party may notify the other of in writing.

                 13.10     Time of the Essence.  Time is of the essence under
this Lease, and all provisions herein relating thereto shall be strictly
construed.

                 13.11     Captions for Convenience.  The headings and captions
hereof are for convenience only and shall not be considered in interpreting the
provisions hereof.

                 13.12     Severability.  If any provision of this Lease shall
be held invalid or unenforceable, the remainder of this Lease shall not be
affected  thereby, and there shall be deemed substituted for the affected
provision a valid and enforceable provision as similar as possible to the
affected provision.

enforced according to the laws of the State of Colorado.

                 13.14     Entire Agreement.  This Lease and any exhibits
referred to herein, constitute the final and complete expression of the
parties' agreements with respect to the Demised Premises and Tenant's occupancy
thereof.  Each party agrees that it has not relied upon or regarded as binding
any prior agreements, negotiations, representations, or understandings, whether
oral or written, except as expressly set forth herein.

                 13.15     No Oral Amendment or Modifications.  No amendment or
modification of this Lease, and no approvals, consents or waivers by Landlord

the party to be bound.

                 13.16     Real Estate Brokers.  Each party hereto represents
and warrants to the other that it has not incurred any liability for the
payment of any fee or commission to any broker or other agent in connection
with the negotiation and execution of this Lease and each party agrees to
indemnify and hold the other party harmless from any damages which may be
incurred by the other party as a result of a breach by the indemnifying party
of the foregoing warranty.

                 13.17     Relationship of Landlord and Tenant.  Nothing
contained herein shall be deemed or construed as creating the relationship of
principal and agent or of partnership, or of joint venture by the parties
hereto, it being understood and agreed that no provision contained in this
Lease nor any acts of the parties hereto shall be deemed to create any
relationship other than the relationship of Landlord and Tenant.

                 13.18     Limitation on Personal Liability of Landlord.
Notwithstanding anything to the contrary contained in this Lease, it is
understood and agreed that there shall be no personal liability on the part of
the Landlord or any of its beneficiaries, successors or assigns, with respect
to any of the terms, covenants and conditions of this Lease, and Tenant shall
look solely to the equity of Landlord in the Demised Premises in the event of
any default or liability of Landlord under this Lease, such exculpation of
liability to be absolute and without any exception whatsoever.

                 13.19     Authority of Tenant.  Each individual executing this
Lease on behalf of Tenant represents and warrants that he is duly authorized to
deliver this Lease on behalf of Tenant and that this Lease is binding upon
Tenant in accordance with its terms.

                                                               September 1, 1997


         FOR VALUE RECEIVED, Contractors Heating & Supply, Inc., a Texas
corporation (herein called "Maker"), promises to pay to the order of Gambray,
Inc. (formerly known as Contractors Heating and Supply Company), a Colorado
corporation (together with any subsequent holder of this note, "Payee"), at 700
Broadway, Suite 800, Denver, Colorado  80203, or at such place as the holder of
this note may hereafter designate in writing, in immediately available funds
and in lawful money of the United States of America, the principal sum of One
Million Two Hundred Thousand and No/100 Dollars ($1,200,000.00), together with
interest on the unpaid principal balance of this note from time to time
outstanding until maturity at the Stated Rate; provided, that for the full term
of this note the interest rate produced by the aggregate of all sums paid or
agreed to be paid to the holder of this note for the use, forbearance or
detention of the debt evidenced hereby shall not exceed the Ceiling Rate.

         "Stated Rate" means, on any day, a rate per annum equal to the Prime
Rate for that day plus one-half percent (0.5%), provided, that if on any day
the Stated Rate shall exceed the Ceiling Rate for that day, then the Stated
Rate shall be fixed at the Ceiling Rate on that day and on each day thereafter
until the total amount of interest accrued at the Stated Rate on the unpaid
balance of this note equals the total amount of interest which would have
accrued if there were no Ceiling Rate.  However, neither the maturity of this
note nor Maker's privilege (if any) to prepay it shall be affected by this
paragraph.

         "Prime Rate" means, on any day, the prime rate for that day as
announced from time to time by NationsBank of Texas, N.A.  Without notice to
Maker or any other person or entity, the Prime Rate shall automatically
fluctuate upward or downward as and in the amount by which said prime rate
fluctuates, with each change to be effective as of the date of each change in
said prime rate.

         "Ceiling Rate" means, on any day, the maximum nonusurious rate of
interest permitted for that day by applicable Colorado law permits the higher
interest rate, stated as a rate per annum.

         Interest shall be computed for the actual number of days elapsed in a
year consisting of 365 or 366 days, as the case may be.





                                                                  INITIALLED FOR

<PAGE>   55
         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 refund to the payor or, at the holder's option,
credit against the principal of this note 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 principal of this note, together with accrued and unpaid interest
on the unpaid balance of this note, shall be due and payable in three (3) equal
annual principal installments of Four Hundred Thousand Dollars ($400,000.00)
each, together with all accrued and unpaid interest on each installment date.
The first installment shall be due and payable on August 31, 1998, and a like
installment shall be due and payable on the same day of each succeeding year
thereafter until this note shall have been fully paid and satisfied; provided,
that on August 31, 2000, the final maturity of this note, all principal and
accrued interest then unpaid shall be due and payable.  All payments shall be
applied first to costs of collection, then to accrued interest, with the
balance to principal.

         Maker may at any time pay the full amount or any part of this note
without payment of any premium or fee.  All prepayments shall be applied first
to costs of collection, then to accrued interest, with the balance to
principal.  Maker shall prepay this Note in full upon (a) the sale of all or
substantially all of its assets, other than to ACR Group, Inc., a Texas
corporation ("Parent") or a wholly-owned subsidiary of Parent, or (b) a sale of
all of the capital stock of Maker or any other transaction pursuant to which
Parent ceases to be the sole shareholder of Maker.

         Maker shall be in default under this note ("Default") upon: (a)
Maker's failure to pay any principal or accrued interest owing on this note
when due (such default not having been cured after ten (10) days written notice
thereof);

         (b) the occurrence of any default under that certain Lease Agreement
of even date herewith made between Maker and Payee ("Lease") which is not cured
within any cure period specified in the Lease; or

         (c) the occurrence of any default under the Security Agreement
(defined below) which is not cured within any cure period specified in the
Security Agreement.

         Upon a Default, the whole principal sum of this note plus accrued
interest and all obligations of Maker to Payee, direct or indirect, absolute or
contingent, now existing or hereafter arising, shall, at the option of Payee,
become immediately due and payable without further notice or demand, and Payee
shall have and may exercise any or all of the rights and remedies provided
herein and under applicable laws.  Following a Default by Maker, overdue





                                                                  INITIALLED FOR

principal, accrued and unpaid interest and (to the extent permitted under
applicable law) overdue interest, whether caused by acceleration of maturity or
otherwise, shall bear interest at a rate equal to five (5) percentage points
above the Stated Rate, until paid, and shall be payable monthly or, at the
option of the Payee hereof, on demand.

         All notices which are permitted or required under this note shall be
in writing and shall be deemed delivered, sent and received when delivered
personally, or if sent by mail, five (5) business days after being mailed by
registered or certified mail, postage prepaid, or, if by reputable overnight
courier, one (1) business day after deposit therewith, addressed as follows, or

                               SECURITY AGREEMENT


         THIS SECURITY AGREEMENT (the "Agreement") is made September ____,
1997, effective as of September 1, 1997, by and between Contractors Heating &
Supply, Inc., a Texas corporation (the "Debtor"), and Gambray, Inc. (formerly
known as Contractors Heating and Supply Company), a Colorado corporation (the
"Secured Party").  Debtor and Secured Party agree as follows:

         Section 1.       Indebtedness.  The security interest granted pursuant
to Section 2 hereof secures the prompt and unconditional payment of the
indebtedness evidenced by that certain promissory note executed by Debtor
payable to Secured Party dated of even date herewith in the original principal
amount of $1,200,000.00 together with all renewals, extensions, rearrangements
or substitutions thereof, if any, whether evidenced by any note or other
instrument or agreement, modifications, and replacements thereof (in whole or
in part) (the "Note").  The indebtedness evidenced by the Note shall be
referred to herein as the "Secured Indebtedness".

         Section 2.       Grant of Security Interest; Collateral.  In order to
secure the prompt and unconditional payment of the Secured Indebtedness and the
performance of the obligations, covenants, agreements and undertakings herein
described, Debtor hereby grants to Secured Party a security interest in and
mortgages, assigns, transfers, delivers, pledges, sets over and confirms to
Secured Party all of Debtor's remedies, powers, privileges, rights, titles and
interests (including all power of Debtor, if any, to pass greater title than it
has itself) of every kind and character now owned or hereafter acquired,
created or arising in and to the following:

         The machinery and equipment described on Exhibit A attached hereto,
         along with all accessions, appurtenances and additions to and
         substitutes for any of the foregoing and all products and proceeds of
         any of the foregoing, together with all renewals and replacements of
         any of the foregoing

         All of the properties and interest described above are herein
collectively called the "Collateral".  The inclusion of proceeds does not
authorize Debtor to sell, dispose of or otherwise use the Collateral in any
manner not authorized herein.

         Section 3.       Payment of Secured Indebtedness.

         3.1     Direct Obligations.  Debtor shall pay to Secured Party any sum
or sums due or which may become due to Secured Party and which is secured
hereby.

         3.2     Expenses.  Debtor shall pay to Secured Party on demand all
expenses and expenditures, including reasonable attorneys' fees and other legal
expenses incurred or paid by any Lender or Secured Party in exercising or
protecting the interests, rights and remedies of Secured Party under this
Agreement.

         Section 4.       Events of Default.  Debtor shall be in default under
this Agreement upon the happening of any of the following events or conditions
("Event of Default"):
<PAGE>   60
         (a)     any part of the Secured Indebtedness is not paid when due,
                 whether by lapse of time or acceleration or otherwise, unless
                 Secured Party declares the default fully cured to Secured
                 Party's satisfaction within ten (10) calendar days after such
                 due date.

         (b)     The Debtor or any obligor under this Note fails to perform,
                 observe or comply with, or defaults under, any of the material
                 terms, covenants, conditions or provisions contained in the
                 Note or this Agreement, as the same may be amended,
                 supplemented, restated or replaced from time to time.

         (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

                 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

                 portion of its property.

         (e)     a default under the Lease of even date herewith between
                 Secured Party and Debtor which is not cured within any cure
                 period specified therein.

         Section 5.       Secured Party's Rights and Remedies in Event of
                          Default.

         (a)     Upon the occurrence of an Event of Default, and at any time
                 thereafter, Secured Party may declare the Secured Indebtedness
                 immediately due and payable and shall have the rights and
                 remedies of a secured party under the Colorado Commercial
                 Code, as amended, and under other applicable laws of each
                 state having jurisdiction over the Collateral or any part
                 thereof, including without limitation thereto, the right to
                 sell, lease or otherwise dispose of any or all of the
                 Collateral and the right to take possession of the Collateral,
                 and for that purpose Secured Party may enter upon any premises
                 on which the Collateral or any part thereof may be situated
                 and remove the Collateral or books and records evidencing
                 same, or may require Debtor to assemble the Collateral and
                 make it available to Secured Party at a place to be designated
                 by Secured Party which is reasonably convenient to both
                 parties.  Unless the Collateral is perishable or threatens to
                 decline speedily in value or is of a type customarily sold on
                 a recognized market, Secured Party will send Debtor reasonable
                 notice of the time and place of any public sale thereof or of
                 the time after which any private sale or other disposition
                 thereof is to be made.  The requirement of sending reasonable
                 notice shall be met if such notice is mailed, postage prepaid,
                 to Debtor at the address designated in this Agreement at least
                 ten (10) days before the time of the





                                       2
<PAGE>   61
                 sale of disposition.  Expenses of retaking, holding, preparing
                 for sale, selling or the like shall include Secured Party's
                 reasonable attorneys' fees and legal expenses, plus interest
                 thereon at the maximum non-usurious rate permitted by
                 applicable law with respect to Debtor.  Debtor shall remain
                 liable for any deficiency.

         Any amounts held, realized or received by Secured Party from any sale
or other disposition of the Collateral or any part thereof, and all amounts
received by Secured Party pursuant to collection of accounts shall be applied
by Secured Party in the following order to:

                 (1)      All costs, expenses and liabilities of Secured Party
                          (including attorneys' fees and expenses) incurred in
                          connection with the exercise of Secured Party's
                          rights under this Agreement or protecting its
                          interest in the Collateral; and then

                 (2)      the payment of all Secured Indebtedness.

         (b)     Secured Party may remedy any default and may waive any default
                 without waiving the default remedied or without waiving any
                 other prior or subsequent default.

         (c)     The remedies of Secured Party hereunder are cumulative, and
                 the exercise of any one or more of the remedies provided for
                 herein shall not be construed as a waiver of any of the other
                 remedies of Secured Party.

         (d)     NOTHING IN THIS AGREEMENT IS INTENDED TO PREVENT DEBTOR OR
                 SECURED PARTY FROM RESORTING TO JUDICIAL PROCESS AT EITHER
                 PARTY'S OPTION.

         (e)     Debtor agrees that, in performing any act under this
                 Agreement, time 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
                 right or remedy shall not be a waiver of any obligation of
                 Debtor hereunder or any right of Secured Party or constitute a
                 waiver of any other similar default subsequent occurring.

         Section 6.       Representations and Warranties.

         6.1     Capacity.  The execution, delivery and performance of this
Agreement are within Debtor's powers, have been duly authorized by all
necessary and appropriate action, and are not in contravention of any law or
the terms of Debtor's Articles of Organization or any amendment thereto, or of
any indenture, agreement, undertaking or other document to which Debtor is a
party or by which Debtor or any of Debtor's property is bound or affected.

         6.2     Title to Collateral.  Debtor is the owner of the Collateral,
free of all security interests, mortgages, liens and other encumbrances except
for the security interest granted to Secured Party under this Agreement, and
Debtor has the unconditional authority to grant the security interest to
Secured Party pursuant to this Agreement.  Debtor shall maintain the





                                       3
<PAGE>   62
Collateral free and clear of all liens, security interests and encumbrances and
shall pay all taxes when due.

         6.3     Validity of the Agreement.  This Agreement constitutes the
legal, valid and binding obligation of Debtor enforceable in accordance with
the terms hereof, except as enforceability may be limited by applicable
bankruptcy and insolvency laws and laws affecting creditors' rights generally.

         Section 7.       Additional Agreements.

         7.1     Further Actions by Debtor.  Debtor shall, on request by
Secured Party, execute, acknowledge, deliver and record or file such further

specifically filing of UCC-1 financing statements and any renewals, extensions,
rearrangements or substitutions thereof or of the Note.

carried by owners of similar businesses and properties in the same general
areas in which Debtor operates.  Upon the request of Secured Party, Debtor
shall furnish Secured Party a schedule setting forth in reasonable detail the
insurance coverage maintained by Debtor on the Collateral.  All such insurance
policies shall contain endorsements showing Secured Party as a loss payee, as
its interests may appear.

         7.4     Other Security Interests/Subordination.  The Debtor will not,
without the prior written consent of the Secured Party:  (a) grant any security
interest or any other interest in any of the Collateral, or (b) subordinate or
permit the subordination of the security interest granted to the Secured Party
herein to the interest of any other person or entity in or to any of the
Collateral.  Any attempt to do any of the foregoing without the prior written
consent of the Secured Party shall be void and ineffective as against the
Secured Party and shall constitute a default under the terms of this Agreement.

         7.5     Other Understandings.  Debtor shall:

         (a)     at the Debtor's sole cost and expense, appear in and defend

                 any manner connected with the Collateral or the Secured
                 Indebtedness, and pay all costs and expenses of the Secured
                 Party, including attorneys' fees in a reasonable sum, in any

                 violation of any provision of this Agreement, or any
                 applicable statute, regulation or ordinance or any policy of
                 insurance covering the Collateral;

<PAGE>   63
         (d)     pay promptly when due all taxes, assessments, charges,

                 Collateral and provide the Secured Party with such records and
                 such other reports and information relating to the Collateral
                 as the Secured Party may reasonably request from time to time;
                 and

         (g)     deliver promptly to the Secured Party copies of all material
                 notices or communications received by the Debtor concerning
                 the Collateral.

agreement contained herein, Secured Party may perform, or cause performance of,
such agreement, and the expenses of Secured Party incurred in connection
therewith shall be payable by the Debtor to Secured Party on demand.  Secured
Party shall not be obligated to perform or discharge, nor does it hereby
undertake to perform or discharge, any obligation, duty or liability relating
to the Collateral or by reason of this Agreement and Debtor shall perform and
discharge all of its obligations, duties and liabilities with respect to any
Collateral.  Debtor hereby agrees to indemnify Secured Party against and hold
it harmless from any and all liability, loss or damage which it may or might
incur by reason of this Agreement, and against and from any and all claims and
demands whatsoever which may be asserted against it by reason of any alleged
obligation or undertaking on its part to perform or discharge any of the terms,
covenants or agreements with respect to any Collateral (except any liability
arising as the result of the Secured Party's willful misconduct).  Should
Secured Party incur any such liability, loss or damage relating to the
Collateral or by reason of this Agreement, or in the defense against any such
claims or demands, the amount thereof, including costs, expenses and reasonable
attorneys' fees, together with interest at the default rate set forth in the
Note shall be included in the Secured Indebtedness secured hereby, and Debtor
shall reimburse Secured Party therefor immediately upon demand, and upon the
failure of Debtor to do so, Secured Party may deem the Debtor in default of
this Agreement and exercise all remedies granted hereby.

         7.8     Successors and Assigns.  Subject to Section 7.6 and the terms
of the Note, this Agreement shall be binding upon and inure to the benefit of
the parties hereto and the successors, representatives, receivers, trustees and
assigns of those parties.

Agreement have been inserted for convenience only and shall be given no
substantive meaning or significance whatever in construing the terms and
provisions of this Agreement.

                              [GUARANTY AGREEMENT]
<PAGE>   70
                               GUARANTY AGREEMENT


         THIS GUARANTY (this "Guaranty") is executed and delivered September
____, 1997, effective as of September 1, 1997, by ACR GROUP, INC., a Texas
corporation (Guarantor"), in favor of GAMBRAY, INC. (formerly CONTRACTORS
HEATING AND SUPPLY COMPANY) a Colorado corporation ("CHS").

                                    RECITALS

         A.      Guarantor is the sole shareholder of Contractors Heating &
Supply, Inc., a Texas corporation ("Purchaser") formed for the sole purpose of
purchasing substantially all of the assets and assuming substantially all of
the liabilities of CHS under the terms of an Asset Purchase Agreement dated as
of September 8, 1997 (the "Purchase Agreement").  Capitalized terms not defined
herein shall have the meanings set forth in the Purchase Agreement.

         B.      As an inducement to CHS entering into the Purchase Agreement,
Guarantor has agreed to guarantee the payment and performance by Purchaser of
Purchaser's obligations under the Note, Lease and the leases listed on Exhibit
A hereto (the "Assigned Leases").

                                   AGREEMENT

         NOW THEREFORE, in consideration of CHS entering into the Purchase
Agreement and other good and valuable consideration, the receipt and
sufficiency of which are acknowledged, Guarantor hereby agrees as follows:

         1.      Guarantor hereby agrees to and does guarantee the full, prompt
and punctual payment of any and all amounts due to CHS and the performance of
all other obligations of Purchaser to CHS under the Note, Lease and Assigned
Leases (the "Guaranteed Obligations") as and when the same become due, whether
at maturity, by acceleration or otherwise.  Guarantor agrees that this is a
guaranty of payment and not of collection.  This Guaranty is irrevocable and
absolute and if for any reason any amount due CHS under the Note or Lease shall
not be paid when due or Purchaser fails to pay or perform any of the other
Guaranteed Obligations, Guarantor shall pay or perform promptly such Guaranteed
Obligations without further notice or demand to Purchaser or Guarantor.

         2.      The obligations of Guarantor hereunder are independent of the
obligations of Purchaser and any other guarantor or other person who may become
liable with respect to the Guaranteed Obligations.  Guarantor is jointly and
severally liable with Purchaser and any other guarantor for the full and timely
payment and performance of all of the Guaranteed Obligations.  Guarantor
expressly agrees that a separate action or actions may be brought and
prosecuted against Guarantor, whether or not any action is brought against
Purchaser, any other guarantor, or any other person for any Guaranteed
Obligations and whether or not Purchaser, any other guarantor, or any other
person is joined in any action against Guarantor.  Guarantor further agrees
that CHS shall have no obligation to proceed against any security for the
Obligations prior to enforcing this Guaranty against Guarantor, and that CHS
may pursue or omit to pursue any and all rights and remedies CHS has against
any person or with respect to any security in any order or simultaneously or in
any other manner.
<PAGE>   71
         3.      Failure by Guarantor to pay or perform any of the Guaranteed
Obligations when due shall constitute a default under this Guaranty.  Upon a
default by Guarantor under this Guaranty, CHS shall have all remedies available
at law or in equity.  In the event CHS commences any action to enforce its
rights under this Guaranty following a default by Guarantor, CHS shall be
entitled to recover from Guarantor all of CHS's costs and expenses in
connection therewith, including reasonable attorneys' fees and other costs.

         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
Guaranteed Obligations, by waiver of any right against Purchaser, by settlement
or compromise of any or all of the Guaranteed Obligations, or by occurrence of
any other event or circumstances which might otherwise constitute a defense
available to, or discharge of, Guarantor.

         5.      Any sums of money CHS receives from or for the account of
Purchaser (other than regular installment payments or regular rent payments
under the Lease when Purchaser is not in default under any of the Guaranteed
Obligations) may be applied by CHS to reduce any of the Guaranteed Obligations
or any other liability of Purchaser to CHS, as Purchaser in Purchaser's
discretion deems appropriate.

         6.      This Guaranty shall be governed by the laws of the State of
Colorado (without regard to any conflict- of-law provisions thereof).

                    [SUBORDINATION AGREEMENT AND ASSIGNMENT]
<PAGE>   75
                     Subordination Agreement and Assignment

         THIS AGREEMENT made this ____ day of __________, 1997, from ACR Group,
Inc. and Contractors Heating and Supply, Inc., a Texas corporation (hereinafter
called "Debtor") and Gambray, Inc., formerly known as Contractors Heating and
Supply, Inc., a Colorado corporation (hereinafter called "Creditor"), in favor
of NationsBank of Texas, N.A.  (hereinafter called the "Bank");

         WHEREAS, Debtor is indebted to the Bank and/or it is contemplated that
Debtor may from time to time in the future become indebted to the Bank for
other and additional sums; and where the term "Indebtedness of Debtor to the
Bank" is used herein, it shall mean all debts and liabilities of Debtor to the
Bank, whether such debts or liabilities may now exist or are hereafter incurred
or arise, and whether the obligation or liability of Debtor thereon be direct,
contingent, primary, secondary, joint, several, joint and several, or otherwise,
and irrespective of the manner in which, or the person or persons in whose
favor such debts or liabilities may at their inception have been, or may
hereafter be created, or the manner in which they may have been or may
hereafter be acquired by the Bank; and

         WHEREAS, Debtor is likewise indebted to Creditor in the amount of
$1,200,000.00 as of this date consisting of: a promissory note as of even date
herewith (the "Note") and whereas it is contemplated that Debtor may from time
to time become indebted in other or additional amounts to Creditor and all such
debts and liabilities of Debtor to Creditor other than lease liabilities shall
be affected by this Agreement, whether such debts or liabilities now exist or
are hereafter incurred or arise, and whether the obligation of Debtor thereon
be direct, contingent, primary, secondary, joint, several, joint and several,
or otherwise, and irrespective of whether such debts or liabilities be
evidenced by note, contract, open account, or otherwise, and irrespective of
the person or persons in whose favor such debts or liabilities may at their
inception have been or may hereafter be created, or the manner in which they
have been or may hereafter be acquired by Creditor;

         NOW, THEREFORE, to induce the Bank to extend financial accommodation
and credit to Debtor and in consideration of loans which may be simultaneously
or hereafter made by the Bank to Debtor, Debtor and Creditor hereby agree as
follows:

         1.      Subordination. Subject to the terms of the Addendum, until all
indebtedness of Debtor to the Bank now existing or hereafter incurred, whether
or not represented by negotiable instruments or other writings,and whether or
not originally contracted with the Bank, has been fully paid and satisfied with
interest, liquidated damages, penalties and attorneys' fees (to the extent
Debtor is liable to Bank therefor), Creditor shall not demand or receive from
Debtor any part of the indebtedness now owing by Debtor to Creditor, or that
may hereinafter be due and payable to Creditor by Debtor, or any security
therefor, and Debtor shall not make payment thereof or give security therefor
to Creditor except in conformity with this Agreement; provided, however, that
until the Bank gives written notice to Creditor to the contrary, Creditor may
receive from Debtor and retain (i) current interest as it accrues and becomes
payable on the principal of the debt due to Creditor, and (ii) regularly
scheduled payments of principal. Creditor waives all notice of the acceptance of
this Agreement by the Bank, or of the creation, renewal, extension or accrual
of any obligations of Debtor to the Bank, or of reliance of the Bank upon this
Agreement.

         2.      Assignment. If at any time while this Agreement is in effect,
any bankruptcy proceedings are filed by or against Debtor or, or a receiver is
appointed for Debtor or any of its property, or an assignment for creditors is
made by Debtor, or Debtor is involved in any insolvency proceedings of any
nature, the Bank shall have the right to file a claim on behalf of Creditor in
all such proceedings, and to collect and receive all payments that may be
declared or become payable on such claim of Creditor in any such proceedings,
and the Bank is hereby irrevocably appointed attorney for Creditor with full
power to act in the name of Creditor for such purpose in all such proceedings.

         3.      Creditor's Receipts. If prior to the satisfaction of all
indebtedness of Debtor to the Bank, Creditor receives any payment or
security not permitted by this Agreement for or on account of the claims and
demands of Creditor against Debtor, Creditor shall forthwith deliver such
payment or security to the Bank, in precisely the form received, except for
Creditor's endorsement when necessary, for application on account of such
indebtedness of Debtor to the Bank. In such manner as the Bank may elect, and
until so delivered such payment or security shall be held in trust by Creditor
as the property of the Bank. In the event of the failure of Creditor to endorse
any instrument for the payment of money so received by Creditor, the Bank is
irrevocably appointed attorney for Creditor with full power to make such
endorsement and with full power of substitution.
<PAGE>   76
         4.    Modifications. The Bank may, in its discretion at any time and 
from time to time, without further consent of or notice to Creditor, and with
or without valuable consideration, release any person primarily or secondarily
liable upon the indebtedness of Debtor to the Bank or may permit substitutions
or withdrawals of any security or collateral at any time securing the payment
of said indebtedness, or release any such security or collateral, or renew or
extend or accept partial payments upon said indebtedness, or alter, in such
manner as the Bank shall deem proper, the terms of any instrument evidencing or
securing said indebtedness, or any  part thereof, without in any manner
impairing its rights hereunder. It shall not be necessary for the Bank, in
order to enforce its rights hereunder, to institute suit or exhaust its
remedies against any person obligated to pay said indebtedness. In the event
that Creditor is an individual, all rights and privileges accorded the Bank in
this Section may be exercised after as well as before the death of
Creditor.
                                                                                
         5.    Representations and Covenants. Creditor and Debtor represent that
there is no defense, offset, or counterclaim to the amount now due to Creditor
from Debtor, and that such amount is not represented by any notes or other
negotiable instruments, or if represented by notes or other negotiable
instruments, that they will be endorsed with proper notice of this Agreement. At
no time hereinafter will any part of any amount due to Creditor from Debtor be
represented by any notes or other negotiable instruments or other writings,
except to the extent now so represented, or except such notes, other negotiable
instruments, or other writings as the Bank shall request Debtor to execute for
the purpose of evidencing such indebtedness or any part thereof. Creditor shall
not, without the prior written consent of the Bank, transfer or dispose of any
claims or demands of Creditor against Debtor. Notwithstanding any such
disposition, if made without the consent of the Bank, any claim so transferred
or disposed of shall continue to be subject to the terms of this Agreement in
all respects.

         6.    Books. Debtor will render to the Bank upon demand and from time 
to time a statement of the account of Creditor with Debtor, and will give the
Bank access from time to time to the books of Debtor in order that the Bank may
make a full examination of the state of accounts due to Creditor by Debtor.

         7.    Default. In the event of a breach by either Creditor or Debtor 
of any of the terms of this Agreement uncured after ten days notice, all 
indebtedness of Debtor to the Bank shall, at the option of the Bank to be
exercised in its discretion, without demand upon either Creditor or Debtor,
become immediately due and payable.     

         8.    Waiver. No waiver shall be deemed to have been made by the Bank 
of any of its rights hereunder unless such waiver is in writing, signed by the
Bank, and then only with respect to the specific instance involved, and shall
in no way impair or offset the rights of the Bank, or the obligations of Debtor
and Creditor, in any other respect or at any other time. The rights of the Bank
hereunder are cumulative of all other rights of the Bank under any other
agreement or by law.

         9.    Successors. The terms "Debtor" and "Creditor" as used in this 
Agreement shall include the individuals, associations, partnerships, or
corporations named herein, and any successor individuals, associations,
partnerships, or corporations to which all or substantially all of the business
or assets of Debtor or Creditor shall be transferred; and in the case of a
partnership any new partnership which shall be created by reason of the
admission of any new partner or partners, or the dissolution of the existing
partnership by the death, resignation, or other withdrawal of a partner, and in
the case of a corporation, any other corporation into or with which Debtor or
Creditor shall be merged, consolidated, reorganized or absorbed.

         10.   Other Documents. Debtor and Creditor each agree to execute such 
further instruments, documents and agreements as may be, in the opinion of the
Bank, from time to time, reasonably necessary or appropriate to fully carry out
the intent and purpose of this Agreement.

         11.   Benefit. This Agreement shall be binding upon each of Debtor 
and Creditor, and their respective heirs, legal representatives, successors and
assigns, and shall inure to the benefit of the Bank, and its successors and
assigns.

         12.   Situs. This Agreement has been executed and delivered in the 
State of Texas, shall be performable in Dallas, Dallas County, Texas, and shall
be governed by and construed in accordance with the laws of the State of Texas.

         IN WITNESS WHEREOF Creditor and Debtor have executed this Agreement as
of the date referenced above.

                             [EMPLOYMENT AGREEMENT]
<PAGE>   84
                    EMPLOYMENT AND NONCOMPETITION AGREEMENT




         THIS EMPLOYMENT AND NONCOMPETITION AGREEMENT (the "Agreement") is
entered into by and between Contractors Heating & Supply, Inc., a Texas
corporation having its principal place of business at 70 Santa Fe Drive,
Denver, Colorado 80223 (the "Company"), and Brad Brady ("Employee"), who
resides at 7113 S. Owens St., Littleton, Colorado 80127. 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 on a full-time basis, 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 material rules,
policies, practices, directives and procedures of the Company which are
communicated to Employee and are consistent with those applicable to other
executives of the Consolidated Group (as defined below).


                                   ARTICLE II

         The initial term of this Agreement shall begin on the date hereof and
terminate on February 28, 2002, 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.  Except as expressly set forth
herein, Employee is not entitled to severance compensation benefits upon the
termination of his employment with the Company (whether voluntary or
involuntary).
<PAGE>   85
         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

                 (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 and such breach is not cured within thirty
         (30) days after written notice from the Company specifying the breach,
         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 fail 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 and such failure is not due to the lack of adequate
         debt or equity financing necessary to achieve the Forecast Income.





                                       2
<PAGE>   86
         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 terminate as of the date of termination (except as may
otherwise be required by law).

         In the event that the employment of Employee hereunder is terminated
by the Company other than for Cause, Employee shall be entitled to receive
payments of Base Salary (as provided 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 Base Salary 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





                                       3
<PAGE>   87
         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 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).





                                       4
<PAGE>   88
         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, within a one hundred (100) mile radius of either Denver, Colorado or
Albuquerque, New Mexico, directly or indirectly, engage in any business, or
become affiliated as an agent, advisor, partner, officer, director, employee,
proprietor, consultant, stockholder or independent contractor of any business
that competes with any business in which the Company has engaged at any time
during Employee's employment hereunder or engages in at the time of Employee's
employment with the Company.  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 areas within a one hundred (100) mile radius of both Denver,
Colorado and Albuquerque, New Mexico, 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






                                       5
<PAGE>   89
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 and adequate proof
(as determined by the court) that Employee has breached the covenant, 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, if the Company or other member of the Consolidated Group is the
prevailing party.  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 Colorado and shall be enforceable
in the City and County of Denver, Colorado.  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 recognized or enforced.  This Agreement may not be amended except by a
written agreement executed by the Company and Employee which makes specific
reference to this Agreement.

business interests require a confidential relationship between it and its
consultants and the fullest practical protection and confidential treatment of
its trade secrets, proprietary trade practices, and other proprietary
information regarding the business or financial affairs of the Company.
Accordingly, Brady agrees that during the term of this Agreement and at all
times thereafter he will:

                 (1)      Keep secret and confidential all such confidential
         information, trade secrets, proprietary trade practices, customer
         lists and proprietary business practices of the Company (written or
         unwritten), and Brady 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, ACRG, or any other direct or
         indirect subsidiary of ACRG (collectively the "Consolidated Group")
         any of the foregoing information, including, without limitation, the
         following: (a) confidential information identifying or tending to
         identify any of the customers, suppliers or employees of the Company
         or any member





                                       2
<PAGE>   97
         of the Consolidated Group; (b) confidential 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) confidential and proprietary 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 (i) that 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 in
         connection with a legal proceeding, or to respond to a valid inquiry
         by a governmental authority, (ii) that has been received by Brady from
         a third party without breaching an obligation owed to the Company or
         (iii) that is known in the trade or industry or that 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 in violation of
         Section V hereof, 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,
         Brady 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 termination of this Agreement, 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, upon termination of this Agreement for any reason, Brady
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
retained by him on behalf of Contractors Heating and Supply Company, a Colorado
corporation, or in connection with the Purchase Agreement and items that are
strictly personal (such as tax forms or compensation records, and Brady's copy
of this Agreement).  Notwithstanding any contrary provision in this Agreement,
Brady shall be permitted access to such books and records of the Company as may
be necessary for him to prepare his personal income tax returns.

                                   SECTION V

                                 NONCOMPETITION

         In consideration of the compensation payable to Brady hereunder,
during the term of this Agreement and for a period of three (3) years after
termination of this Agreement by either Brady or the Company, Brady will not,
within a one hundred (100) mile radius of either the City Hall of Denver,
Colorado, or the City Hall of Albuquerque, New Mexico, directly or indirectly,
engage in the business of  the wholesale distribution of HVACR products or the
manufacture of sheet metal products 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 Brady's services hereunder
are terminated by the Company without Cause or following a default by the
Company or ACR Group, Inc., a Texas corporation, under the Note, the Security
Agreement or the Lease executed in connection with the Purchase Agreement (as
such terms are defined therein) that is not cured within any cure period
specified therein.  For the purposes hereof, "Cause" shall mean: (i)
performance of duties under this Agreement in a grossly negligent manner, or
the breach of any material provisions of this Agreement; (ii) malfeasance,
theft from the Company, embezzlement or conviction of a felony; or (iii)
dishonesty or fraud with respect to the assets or business of the Company.
This restriction applies to any passive investment in securities of any
corporation or other business organization, unless equity ownership is less
than 1%.

         Brady makes the preceding covenants in consideration for, and as a
necessary condition of, his engagement by the Company.  Brady'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 Brady (including any
obligation under this Agreement or any other agreement between Brady 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 Brady may have against the Company or
any other member of the Consolidated Group.  The restrictive covenants of Brady
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.

         Brady expressly acknowledges that the Company conducts business
throughout the areas within a one hundred (100) mile radius of the City Hall of
Denver, Colorado, and the City Hall of Albuquerque, New Mexico, and he
stipulates that the time and area restrictions of the foregoing obligations do
not unduly oppress his future employment or consulting opportunities.  In
addition, Brady 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





                                       4
<PAGE>   99
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 Brady 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.


                                   SECTION VI

                              REMEDIES FOR BREACH

         Brady 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, Brady 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 Brady 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 Brady and adequate proof (as
determined by the court) that Brady has breached the covenants, 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 Brady
of all consequential damages attributable to his breach of the restrictive
covenant and all profit, remuneration, or other consideration that Brady gains
from breaching the restrictive covenant; and (c) reimbursement from Brady 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 if the
Company is the prevailing party.  The Company may exercise any of the foregoing
remedies concurrently, independently, or successively.





                                       5
<PAGE>   100
         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 Colorado and shall be enforceable
in Denver, Colorado.  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 Brady'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) Brady's death; or (3) upon
mutual agreement of parties hereto in writing.


                                  SECTION VIII

Contractors Heating & Supply Co.

Denver, CO 80223

Dear Brad:

Subject:   Pending Sale
           Contractors Heating & Supply Co.

In the event of a sale of your company to the ACR Group, UPG would have a high
degree of interest in continuance of the Fraser-Johnston brand. However, in
accordance with our Sales Agreement, Section 7 A-4, any change in the effective
ownership or control of the distributor would terminate our Sales Agreement.
Therefore, in order to continue with the Fraser-Johnston brand, UPG would need
the same financial and sales commitment that Contractors has brought to the 
party.

Sincerely,



/s/ JERRY VENDITTI
