ITEM 1.  BUSINESS.

General

         ACR Group, Inc. (which, together with its subsidiaries is herein
referred to as the "Company" or "ACRG") is a Texas corporation based in
Houston.  In 1990, the Company began to acquire and operate businesses engaged
in the wholesale distribution of heating, ventilating, air conditioning and
refrigeration ("HVACR") equipment and supplies.  The Company acquired its first
operating company in 1990.  Since 1990, ACRG has acquired or started up seven
additional HVACR distribution companies and now has 31 branch operations in
seven states.  The Company plans to continue expanding in the Sunbelt of the
United States and in other geographic areas with a high rate of economic
growth, both through acquisitions and internal growth.

The HVACR Industry

         The Company's interest in the HVACR distribution industry is a direct
result of the business experience of its Chairman and President, Alex Trevino,
Jr., who has been associated with the industry for over thirty years in varying
capacities, first as owner of his own distribution company and then as
president of various successor companies following the sale of his business.

         The Company sells supplies and equipment to installing contractors and
dealers and to other technically trained customers responsible for the
installation, repair and maintenance of HVACR systems.  Maintenance of a large
and diverse inventory base is an important element in the Company's sales.

         The HVACR supply industry is segmented into discrete categories.
First, it serves both commercial and residential HVACR businesses.  Each of
these segments is further divided into two markets - new construction sales and
replacement and/or repair sales.  Some companies choose to specialize in
serving the new construction markets while others focus on the
repair/replacement market, commonly referred to as the "aftermarket."  ACRG is
not oriented toward any particular segment but instead concentrates on
acquiring and developing profitable businesses in the Sunbelt region of the
United States which have a significant market share within their segment of the
HVACR distribution industry.  The Company believes that its growth strategy is
appropriate in view of the competitive nature of the HVACR industry and the
continuing consolidation in that industry, discussed below.

         There are many manufacturers of products used in the HVACR industry,
and no single manufacturer dominates the market for a range of products. Some
manufacturers





                                     - 4 -
<PAGE>   5
limit the number and territory of wholesalers that may distribute their
products, but exclusivity is rare. Many manufacturers will generally permit any
distributor who satisfies customary commercial credit standards to sell their
products. In addition, there are some manufacturers, primarily of equipment,
that distribute their own products through factory branches.  The widespread
availability of HVACR products to distributors results in significant
competition.  There are several thousand HVACR wholesale distributors in the
United States, and there is no single company or group of companies that
dominates the HVACR distribution industry. The industry traditionally has been
characterized by closely- held businesses with operations limited to local or
regional geographic areas; however, a process of consolidation in this industry
is ongoing, as many of these companies reach maturity and face strategic
business issues such as ownership succession, changing markets and lack of
capital to finance growth.  Management's goal is to attract the present owners
and management of such businesses by offering certain advantages related to
economies of scale: lower cost of products from volume purchasing, new product
lines, and financial, administrative and technical support.

         The Company believes that investing in the HVACR distribution industry
has fewer economic risks than many other industries. Although the HVACR
industry is affected by general economic conditions such as cycles in new home
construction, sales of replacement equipment and repair parts for the existing
base of installed air conditioning and heating systems provides a cushion
against economic swings. The aftermarket is far less susceptible to changes in
economic conditions than the new construction market and now represents
approximately 70% of all units installed annually.  This percentage should
continue to increase as the base of installed systems expands.  Much of the
HVACR industry is also seasonal; sales of air conditioning and heating systems
are generally largest during the times of the year when climatic conditions
require the greatest use of such systems. Sales of refrigeration systems, which
are generally to commercial customers, are subject to less seasonality.

Investments in HVACR Distribution Companies:

         ACR Supply, Inc.

         The Company acquired ACR Supply, Inc. ("ACRS") effective February 28,
         1993, after making an initial investment in the company in 1991.  At
         the end of fiscal 1997, ACRS had twelve branches in Texas and one in
         Louisiana.  Most of ACRS's branches have attained market share
         leadership in their respective areas. In major metropolitan areas such
         as San Antonio and Houston, ACRS encounters significantly more
         competition than in smaller cities.  However, through aggressive sales
         efforts, the Houston branches have achieved a significant, but not
         dominant, share of their local HVACR markets.  The company has yet to
         achieve a significant market share in either San Antonio or McAllen,
         Texas.  In May 1997, ACRS opened its fourteenth





                                     - 5 -
<PAGE>   6
         branch in College Station, Texas.

         ACRS sells primarily to licensed contractors serving the residential
         and light commercial (restaurants, strip shopping centers, etc.)
         markets.  The company's sales mix is approximately 35% equipment and
         65% parts and supplies, with the equipment and parts generally
         directed to the aftermarket and the supplies used principally in new
         construction.

         Heating and Cooling Supply, Inc.

         The Company acquired Heating and Cooling Supply, Inc. ("HCS") in 1990.
         HCS operates from one location in Las Vegas, Nevada. There are
         approximately 20 independent HVACR distributors in the Las Vegas area
         that compete with HCS. Management believes that HCS is among the top
         three of such distributors in terms of annual sales from branch
         operations in the local area.

         HCS's sales growth in the past several years has mirrored the
         well-documented growth of the Las Vegas economy, and approximately 80%
         of HCS's sales are in the new construction markets.  HCS has
         successfully expanded its business in the commercial HVACR market by
         emphasizing the company's capabilities in both the plan and
         specifications market and the specialty products market.  HCS's
         proficiency in these two niches distinguishes it from most other HVACR
         distributors and, as a result, sales to commercial accounts were
         approximately 40% of total sales at the end of fiscal 1997.

         Total Supply, Inc.

         In 1990, the Company organized Total Supply, Inc. ("TSI") to fabricate
         air conditioning ductwork out of fiber glass ductboard, and in 1992
         converted the company's business to HVACR wholesale distribution.
         Since December 1992, TSI has distributed the GMC brand of HVACR
         equipment in the Atlanta trade area.  In 1995, TSI acquired a small
         distributor in south Georgia, which gave the company GMC distribution
         rights to almost the entire state of Georgia.  TSI sells almost
         exclusively to the residential market, and management estimates that
         sales are approximately evenly split between new construction and the
         aftermarket.  The company's sales mix is approximately 68% equipment
         and 32% parts and supplies.

         TSI has four branches located in the Atlanta metropolitan area, one
         branch in Warner-Robins, a suburb of Macon, and one branch in Valdosta
         in far south Georgia.





                                     - 6 -
<PAGE>   7
         Valley Supply, Inc.

         In 1994, the Company organized Valley Supply, Inc. ("VSI") as an HVACR
         distributor in the Memphis, Tennessee trade area, which includes
         southwestern Tennessee, northern Mississippi and western Arkansas.
         The Company was granted the franchise to distribute the GMC line of
         equipment within this trade area, succeeding another distributor which
         ceased business operations.  VSI employs most of the key personnel
         from that former GMC distributor.  Although sales of GMC equipment
         initially comprised virtually all of VSI's sales, management has
         continuously emphasized increasing the breadth of higher profit HVACR
         parts and supplies stocked at VSI.  Approximately 78% of VSI's sales
         consisted of GMC equipment in fiscal 1997.  In fiscal 1997, the
         Company opened a second branch of VSI in Memphis to serve the southern
         section of the city and the north Mississippi trade area.

         Ener-Tech Industries, Inc.

         Effective January 1, 1996, the Company acquired Ener-Tech Industries,
         Inc. ("ETI"), an HVACR distributor with one branch in Nashville,
         Tennessee.  Unlike the Company's other HVACR distribution operations,
         ETI specializes in an industry segment.  ETI sells controls and
         control systems to commercial and industrial end-users, HVACR
         contractors, dealers and other distributors.  ETI also designs and
         assembles control systems used in commercial applications such as
         hospitals, restaurants and supermarkets.  Such control systems perform
         a variety of functions including temperature control and monitoring,
         lighting control and energy management.

         ETI is an authorized distributor for Honeywell, Inc. for much of
         Tennessee and parts of Kentucky.  By providing engineering services
         and assembly processes for its customers in connection with the sale
         of control systems, ETI obtains a higher gross margin on its sales
         than the Company's other distribution businesses.  Additionally, ETI's
         sales tend to be greater in the cooler seasons of the year, when gas
         controls are in higher demand.  In fiscal 1997, a branch of ETI was
         opened in the same physical location as the south Memphis branch of
         VSI.

         Florida Cooling Supply, Inc.

         In March 1996, the Company organized Florida Cooling Supply, Inc.
         ("FCS") and in April 1996, opened four branch operations in central
         Florida.  The state of Florida is among the three largest in the
         United States in terms of installed HVACR systems.  FCS is managed by
         two persons with extensive industry experience in FCS's trade area.
         During fiscal 1997, FCS closed one of the initial four branches, and
         in May





                                     - 7 -
<PAGE>   8
         1997, opened a new branch in Tampa.

         Lifetime Filter, Inc.

         Effective as of January 1, 1997, the Company acquired Lifetime Filter,
         Inc. ("LFI"), a manufacturer of electrostatic air filters which sells
         its products principally to HVACR contractors and dealers by mail
         order.  LFI is based in Katy, Texas, a suburb of Houston.  The Company
         expects to augment LFI's sales by distributing LFI's filters
         throughout the Company's existing wholesale distribution network.


Energy Service Business

         In the early 1980's, the Company's primary business was the design,
installation and management of integrated systems intended to reduce energy
costs ("Systems") for users of commercial, industrial and institutional
facilities.  ACRG did not install any new Systems after 1985.  Pursuant to
service contracts, customers paid ACRG a specified percentage of the utility
cost savings attributable to the Systems over the term of the contract.  The
Company's contracts for its remaining Systems all expired during fiscal 1996,
but the Company continues to manage 13 Systems for a single customer on a month
to month basis.  The Company cannot predict for how long such an informal
arrangement may continue.


Executive Officers of the Registrant

         The Company's executive officers are as follows:

         Anthony R. Maresca has been employed by the Company since June 1985,
serving as Corporate Controller until November 1985 when he was promoted to
Senior Vice President, Chief Financial Officer and Treasurer.  Mr. Maresca is a
certified public accountant.

Employees

         As of February 28, 1997, the Company and its subsidiaries had
approximately 195 full-time employees.  In addition, LFI had approximately 15
workers who are leased from a national staff leasing company.  In May 1997,
these workers became employees of LFI.  Neither the Company nor its
subsidiaries routinely use temporary labor. None of the Company's employees are
represented by any collective bargaining units.  Management considers the
Company's relations with its employees to be good.


ITEM 2.  PROPERTIES.

         The Company and its subsidiaries occupy office and warehouse space
under operating leases with various terms.  Generally, a branch location will
contain 10,000 to 20,000 square feet of showroom and warehouse space.  Branch
locations that include a subsidiary's corporate office will be larger.  The
Company owns the facility occupied by the Pasadena, Texas branch of ACRS.
During fiscal 1997, the Company acquired land in Las Vegas, Nevada and in
Temple, Texas for the purpose of constructing buildings to replace the existing
leased premises.  The Company expects to sell each of the properties to parties
who would construct office/warehouse buildings according to the Company's
specifications and lease them to the Company under long-term arrangements.


ITEM 3.  LEGAL PROCEEDINGS.

         As of February 28, 1997 the Company was not a party to any pending
legal proceeding that is deemed to be material to the Company and its
subsidiaries.


ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY-HOLDERS.

         No matters were submitted to a vote of security holders during the
fourth quarter of the fiscal year ended February 28, 1997.

ITEM 6.  SELECTED FINANCIAL DATA.


         The following selected financial data of the Company have been derived
from the consolidated financial statements.  This summary should be read in
conjunction with the consolidated financial statements and related notes
included in Item 8 of this Report.  As of February 28, 1993, the Company
acquired ACR Supply, Inc.; the accounts of ACRS are consolidated in the Balance
Sheet Data presented herein as of such date.  The results of operations of ACRS
are included in the Income Statement Data only for the fiscal years ending
after February 28, 1993.  Effective March 1, 1993, the Company adopted
Statement of Financial Accounting Standards ("SFAS") No. 109 with respect to
accounting for income taxes.  As a result of implementing SFAS 109, $680,000
was included in net income in fiscal 1994 as the cumulative effect on prior
periods.  The Company has never paid any dividends.

         The Company has not recorded a provision for income taxes other than
alternative minimum taxes and state income taxes for fiscal years 1994 through
1997 because of previously incurred net operating losses for which a tax
benefit had not previously been recorded.  Additionally, the Company determined
in the fourth quarter of fiscal 1997 that a further reduction in the deferred
tax asset valuation allowance was appropriate given expectations of higher
future taxable income and, as a result, recorded an additional tax benefit of
$360,000.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS.

RESULTS OF OPERATIONS

Fiscal 1997 Compared to Fiscal 1996

         Operating income increased 117%, from $764,714 in fiscal 1996 to
$1,658,674 in fiscal 1997, as a result of higher sales and gross profit margin,
despite additional costs relating to the startup of new branch operations.
Operating earnings at ACRS and HCS were particularly strong compared to fiscal
1996.  Operating losses and non-recurring costs associated with the opening of
five branches in fiscal 1997 amounted to more than $550,000.  Net income also
increased significantly, from $183,766 in fiscal 1996 to $1,144,788 in fiscal
year 1997, with higher interest costs offset by a reduction in the deferred tax
asset valuation allowance.

         Sales increased 39%, from $56.5 million to $78.4 million, in fiscal
1997 compared to fiscal 1996.  Same store sales at the 18 branches in operation
in the first quarter of fiscal 1996 increased 16% in both fiscal 1997 and 1996,
with the balance of the increase in fiscal 1997 attributable to sales from FCS,
ETI, three branches of TSI purchased or opened in late 1995 and a second branch
of VSI in Memphis.  All but three of the 18 branches recorded an increase in
sales from fiscal 1996, and new branches subtracted sales from two of the
three.  Sales of equipment manufactured by Goodman Manufacturing Company, and
sold under the GMC and Janitrol brand names, continued to escalate, increasing
to $24 million in fiscal 1997 from $16.5 million in fiscal 1996.  Sales at LFI,
which was acquired in January 1997, represented only 1% of the increase in
sales from fiscal 1996 to fiscal 1997.

         The Company's gross margin percentage increased to 19.2% in fiscal
1997 from 19.0% in fiscal 1996, although the margin percentage on GMC/Janitrol
sales declined from 14.2% to 13.9%.  The gross margin percentage at each of the
Company's newest operations, ETI and FCS, is higher than the overall average,
because of minimal HVACR equipment sales during fiscal 1997 at these companies.
In the HVACR industry, the profit margin on sales of equipment, such as
condensing units, furnaces and heat pumps, is generally less than on sales of
parts and supplies.  In addition, ETI provides engineering services in
connection with sales of its control systems, and is able to command a higher
gross margin on its sales with such value-added services.  LFI, which
manufactures most of the products that it sells, also obtains a much higher
gross margin on its sales than the Company's wholesale operations, but because
only two months of LFI's operations were included in the Company's fiscal 1997
results, this factor had little impact on the Company's overall margin in fiscal
1997.

         Selling, general and administrative costs ("SG&A") as a percentage of
sales declined to 17.7% in fiscal 1997, compared to 17.8% in fiscal 1996.  With
payroll costs representing





                                     - 13 -
<PAGE>   14
57% and 56% of SG&A expenses (10.2% and 10.1% of sales) in fiscal 1997 and
1996, respectively, the Company focuses on increasing the sales volume of each
of its branch operations as a means to generate higher gross profit without a
proportional increase in number of employees or amount of non-payroll expenses.
However, SG&A expenses as a percentage of sales are generally high during the
first year of a new branch operation as sales volume gradually increases.  The
costs associated with opening new branches caused SG&A expenses to remain at a
higher percentage of sales in fiscal 1997 than will be expected as such
branches become more seasoned.  Additionally, the Company recorded a
non-recurring charge of $125,000 during fiscal 1997 for performance-based
compensation pursuant to the employment contract of its chief executive
officer.

         Beginning in fiscal 1997, the Company earned commission revenue from a
supplier by providing warehousing and shipping services to another distributor
of the supplier.  This arrangement has been modified by the supplier such that
revenues in calendar 1997 will be earned at a rate approximately equal to 70%
of the rate in calendar 1996.

         Net energy services income increased 13% from fiscal 1996 to fiscal
1997 as the Company continued to provide services on a month-to-month basis to
its remaining customer, following the expiration of its energy services
contract in 1996.  Management does not expect to negotiate another contract
with the customer, but the customer is partially dependent on the Company for
the proper operation of its HVACR systems.  Management cannot estimate how long
such an informal arrangement may continue.

         Interest expense increased 44% in fiscal 1997 compared to 1996 as a
result of the Company's increased borrowings.  In 1997, interest expense was
1.2% of sales, compared to 1.1% of sales in 1996.  See Liquidity and Capital
Resources, below.  Other non-operating income increased 94% from fiscal 1996 to
fiscal 1997 as the Company strengthened its policy to collect finance charges
from customers with past due balances.

         Current income tax expense consists principally of state income taxes.
As a result of the Company's substantial tax loss carryforwards, the Company
has minimal liability for Federal income taxes. See Liquidity and Capital
Resources, below.  In the fourth quarter of fiscal 1997, the Company determined
that a further reduction in the deferred tax asset valuation allowance was
appropriate given expectations of higher future taxable income and, as a
result, recorded an additional tax benefit of $360,000.

         In April 1997, the Company acquired the assets and liabilities of ACH
Supply, Inc. ("ACH"), a wholesale distributor of HVACR products with two branch
operations in the Los Angeles area.  ACH had sales of $2.8 million in its
fiscal year ended June 30, 1996.  Management of the Company believes that there
are substantial opportunities to increase the business of ACH by opening new
branch operations or acquiring other small distributors over the next several
years.





                                     - 14 -
<PAGE>   15
         In May 1997, the Company entered into a letter of intent to acquire
Contractors Heating & Supply, Inc. ("CHS"), a Denver-based HVACR distributor.
CHS, which had calendar 1996 sales of $20 million, has three branches in
Colorado and one in New Mexico.  CHS's operations include a sheet metal shop
which fabricates products sold through its distribution branches.  See
Liquidity and Capital Resources, below.

Fiscal 1996 Compared to Fiscal 1995

         Operating income declined 19%, from $945,607 in fiscal 1995 to
$764,714 in fiscal 1996, because of lower gross margins on sales, startup costs
associated with the opening of new branch operations, and increased inventory
shrinkage.  Additionally, higher interest costs associated with borrowings
required to support the sales growth of the Company resulted in a reduction of
net income to $183,766 in fiscal 1996, compared to $558,206 in fiscal 1995, a
decline of 67%.

         Sales increased 37%, from $41.3 million in fiscal 1995 to $56.5
million in fiscal 1996, with each subsidiary reporting a significant increase
in sales.  Same store sales at ACRS increased 16% in fiscal 1996, compared to
13% in fiscal 1995.  Sales at TSI increased 72% in fiscal 1996; aggregate sales
at the two branches that existed at the beginning of fiscal 1996 increased 4%
despite the opening during the year of two additional, larger branches within
the sale metropolitan Atlanta trade area.  TSI also acquired two branch
operations in central and south Georgia which expanded the territory in which
TSI has the distribution right to sell the GMC brand of HVACR equipment to
almost the entire state of Georgia.

         Sales at HCS rose 45% in fiscal 1996, principally because of a
substantial increase in the volume of Janitrol sales to the residential market
sector.  Janitrol equipment sales represented 36% of HCS's sales in fiscal
1996, compared to 9% in fiscal 1995, the first year that HCS distributed
Janitrol equipment.  Sales at VSI increased 80% in fiscal 1996 from fiscal
1995, when VSI first opened.  During fiscal 1996, VSI gradually enlarged its
sales of products other than GMC equipment.  Sales of GMC equipment comprised
85% of VSI's sales in fiscal 1996, compared to 90% in fiscal 1995.  The Company
acquired ETI in January 1995, and its sales for the two-month period ended
February 29, 1996 represented only 2% of the increase in the Company's from
1995 to 1996.

         The Company's gross margin percentage declined to 19.0% in fiscal 1996
from 20.7% in fiscal 1995, as a result of the continually increasing percentage
of consolidated sales that are generated by TSI and VSI.  Because TSI and VSI
sell substantially more HVACR equipment than other products, and because their
primary equipment supplier provides incentives to its distributors to induce a
greater volume of sales at lower gross margins, their sales tend to depress the
Company's consolidated gross margin percentage.  In addition, the increase in
Janitrol equipment sales at HCS, as described above, reduced HCS's gross margin
percentage by almost 4% in fiscal 1996 compared to 1995.  The gross margin
percentage at ACRS also declined 1.6% in 1996, as the company gained market
share in





                                     - 15 -

part by negotiating bulk sales to customers at low margins of products that
could be shipped directly to the customer from the manufacturer.

         SG&A expenses as a percentage of sales declined to 17.8% in fiscal
1996, compared to 18.9% in fiscal 1995, following the expected trend as average
sales per branch operation increase.  Net operating income from energy services
decreased 36% from fiscal 1995 to fiscal 1996.  In 1995, the Company recognized
non-recurring revenue following a review of an energy services contract which
revealed that the Company had not received certain funds due under the terms of
the contract.  Excluding revenues from this contract, net energy service income
declined 15% from 1995 to 1996.  All of the Company's remaining energy services
contracts expired in fiscal 1996.

         Interest expense increased 43% in fiscal 1996 compared to 1995 as a
result of the Company's increased borrowings.  Income tax expense consisted
primarily of state income taxes in fiscal 1996 and 1995.

Liquidity and Capital Resources

         Working capital increased from $8,118,061 at February 29, 1996 to
$11,080,075 at February 28, 1997 as a result of the Company's earnings and
borrowings under the Company's revolving credit facility.  Current assets
increased 32% from 1996 to 1997, principally in accounts receivable and
inventory.  Accounts receivable represented 54 days of gross sales at the end
of fiscal 1997, compared to 49 days of sales in receivables at the end of
fiscal 1996 because of slow sales in February 1997 and extended payment terms
that were provided to certain customers in fiscal 1997.  Of the $3.7 million
increase in inventory, $700,000 was attributable to an increase in pre-season
shipments of air conditioning equipment received by ACRS from its primary
supplier, and $1.9 million was located at operations started up or acquired in
fiscal 1997.  The remainder of the increase in inventory was acquired in
anticipation of greater sales than the preceding year.

         The Company has credit facilities with a commercial bank ("Bank")
which include an $8 million revolving line of credit and a $500,000 term loan
facility for the purchase of capital equipment.  At February 28, 1997, the
Company had fully utilized its line of credit with borrowings of $7.4 million
and $.6 million in standby letters of credit and had outstanding borrowings
under the term loan facility of $355,128.  Borrowings under the revolving
credit facility are secured by accounts receivable and inventory, and the
permitted amount of outstanding borrowings at any time is limited to
percentages of certain accounts receivable and inventory.  Borrowings under the
credit line bear interest at the Bank's prime rate plus  1/2%.  Restrictive
covenants of the loan agreement prohibit the Company from paying dividends,
prepaying its debt to The Catalyst Fund, Ltd. (see Note 4 of Notes to
Consolidated Financial Statements) or incurring other debt without the Bank's
consent, and also require the Company to maintain certain financial ratios.
Additional borrowings under the revolving line of credit during fiscal 1997
were used for working capital necessary to





                                     - 16 -

open new branch locations and to support higher levels of sales at all of the
Company's operations.  See Results of Operations - Fiscal 1997 Compared to
Fiscal 1996, above.

         The revolving line of credit matures on February 28, 1998.  As a
result of the Company's acquisitions during 1997, the Company was not in
compliance with certain financial covenants under the revolving line of credit
at February 28, 1997, and the Company has obtained waivers of such violations
from the Bank through August 31, 1997.  On May 12, 1997, as amended on June 10,
1997, the Company obtained a firm commitment from the Bank to refinance the
existing $8 million revolving line of credit with a new $18 million revolving
credit facility, including a $1 million sub-facility for letters of credit.
The new revolving credit facility provides for borrowings, at the Company's
option, at either the Bank's prime rate plus  1/2% or LIBOR plus 3.00%.
Borrowings under the new revolving credit facility will be limited to 85% of
eligible accounts receivable and 50% of eligible inventory amounts. See Note 4
of Notes to Consolidated Financial Statements.

         In connection with its acquisition of LFI, the Company obtained $1.4
million in financing from St. James Capital Partners, L.P. ("St. James"), which
was used to pay the cash portion of the purchase price and various transaction
costs.  The note issued to St. James ("St. James Note") bears interest at 10%
per annum and has an initial maturity date of January 24, 1998.  In connection
with the financing, the Company also issued St. James a warrant to acquire
280,000 shares of the Company's common stock at $1.625 per share.  The Company
may elect to extend the maturity date of the St. James Note for one year past
the initial maturity date, in which case the Company will be required to issue
a warrant for a number of shares equal to 10% of the outstanding indebtedness,
including interest, on the Note.  The Company expects to exercise this option.
None of the principal or accrued interest on the St. James Note is payable
prior to maturity.  The St. James Note is also convertible into common stock of
the Company at $2.40 per share.  The Company also issued a note to an affiliate
of the former owner of LFI for $1,166,662, which bears interest at prime plus
1% and is payable in twelve equal quarterly installments of principal, plus
accrued interest, beginning March 31, 1997.  Both the St. James Note and the
note to the affiliate of LFI's former owner are subordinated to the Bank.  See
Note 4 of Notes to Consolidated Financial Statements.

         The Company made capital expenditures of $1.4 million in fiscal 1997,
of which $410,000 was for land in Las Vegas on which the Company intends to
construct an office/warehouse to replace its existing leased premises, and
$420,000 was for leasehold improvements, equipment and vehicles for new
branches.  The remainder of capital expenditures was principally for the
addition or replacement of vehicles under capital leases.

         The purchase price of the assets and liabilities of CHS is estimated
at $6 million of which $4.8 million will be financed by the Bank under the new
revolving credit facility described above, and $1.2 million will be financed by
the seller.  The Company expects to conclude the acquisition of CHS in the
second quarter of fiscal 1998.  In addition, the





                                     - 17 -
<PAGE>   18
increased facility should provide the funds necessary to finance the expected
growth of existing operations in fiscal 1998.

         Management is engaged in discussions to sell the land that it owns in
Las Vegas and in Temple, Texas to buyers who would construct buildings meeting
the Company's specifications and lease the completed facilities to the Company
under long-term leases.  The purchase of the Las Vegas land was partially
financed by the seller, whose note matures in September 1997.

         The Company has approximately $33 million in tax loss carryforwards
and $1.1 million in tax credit carryforwards.  Such operating loss and tax
credit carryforwards will substantially limit the Company's federal income tax
liabilities in the near future.  Certain provisions of the Internal Revenue
Code ("Code") regulate the amount of additional stock that the Company could
issue without resulting in a change in ownership control, as defined in the
Code.  Should such a change in control be deemed to occur, the Company's
ability to utilize its operating loss and tax credit carryforwards would be
severely restricted.  See Note 6 of Notes to Consolidated Financial Statements.

Seasonality

         The Company's sales volume and, accordingly, its operating income vary
significantly during its fiscal year.  The highest levels of sales occur during
the times of the year when climatic conditions require the greatest use of air
conditioning, since the Company's operations are concentrated in the warmer
regions of the United States.  Accordingly, sales will be highest in the
Company's second quarter ending August 31, and will be lowest in its fourth
fiscal quarter.  The acquisition of CHS, which is based in Denver, may offset
some of the Company's existing seasonality.

Inflation

         The Company does not believe that inflation has had a material effect
on its results of operations in recent years.  Generally, manufacturer price
increases attributable to inflation uniformly affect both the Company and its
competitors, and such increases are passed through to customers as an increase
in sales prices.

Recently Issued Accounting Standards

         In February 1997, the Financial Accounting Standards Board issued SFAS
No. 128, "Earnings per Share," which specifies the computation, presentation
and disclosure requirements for earnings per share.  SFAS No. 128 is effective
for financial statements for periods ending after December 15, 1997, and
earlier adoption is not permitted.

         SFAS No. 129, "Disclosure of Information about Capital Structure," was
issued in February 1997.  This statement is effective for financial statements
for periods ending after December 15, 1997.

         The Company has not yet determined the impact on the consolidated
financial statements from the initial adoption of these standards.

                         REPORT OF INDEPENDENT AUDITORS


The Board of Directors and Shareholders
ACR Group, Inc.

We have audited the accompanying consolidated balance sheets of ACR Group, Inc.
and subsidiaries as of February 28, 1997 and February 29, 1996 and the related
consolidated statements of operations, shareholders' equity, and cash flows for
each of the three years in the period ended February 28, 1997.  Our audits also
included the financial statement schedule listed in the Index at Item 14(a).
These financial statements and schedule are the responsibility of the Company's
management.  Our responsibility is to express an opinion on these financial
statements and schedule based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement.  An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements.  An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation.  We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the consolidated financial position of the
Company and subsidiaries at February 28, 1997 and February 29, 1996 and the
consolidated results of their operations and their cash flows for each of the
three years in the period ended February 28, 1997 in conformity with generally
accepted accounting principles.  Also, in our opinion, the related financial
statement schedule referred to above, when considered in relation to the basic
financial statements taken as a whole, presents fairly in all material respects
the information set forth therein.

1  -     Description of Business and Summary of Significant Accounting Policies

Description of Business

         ACR Group, Inc.'s (the "Company") principal business is the wholesale
distribution of heating, ventilating, air conditioning and refrigeration
("HVACR") equipment, parts and supplies in the southeastern United States,
central and south Texas; and Las Vegas, Nevada.

Principles of Consolidation

         The consolidated financial statements include the accounts of ACR
Group, Inc. and its subsidiaries, all of which are wholly-owned.  All
significant intercompany accounts and transactions have been eliminated.

Use of Estimates

         The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes.  Actual results could differ from those estimates.

Revenue Recognition

         Revenues are recognized at the time merchandise is shipped or
delivered to the customer.

         Beginning in fiscal 1997, the Company earned commission income from a
supplier by providing warehousing and shipping services to another distributor
of the supplier.

Energy Services

         Revenues from energy service contracts, which expired in 1996 and
continue on a month-to-month basis, are recognized when the related energy cost
savings are billed to the user.  These revenues are insignificant to the sales
of the Company and are presented net of costs to provide such services.

Inventories

         Inventories are valued at the lower of cost or market using the
average cost method. Substantially all inventories represent finished goods
held for sale.  The Company has an arrangement with an HVACR equipment
manufacturer and

Inventories (continued)

a field warehouse agent whereby HVACR equipment is held for sale in bonded
warehouses located at the premises of the Company's operations in Georgia, Las
Vegas, and Memphis, with payment due only when products are sold.  Such
inventory is accounted for as consigned merchandise and is not recorded on the
Company's balance sheet.  The cost of such inventory held in the bonded
warehouses was $15,998,345 at February 28, 1997 and $10,881,771 at February 29,
1996.

         The terms of the consignment agreement with the supplier further
provide that merchandise not sold within a specified period of time must be
purchased by the Company.  The Company believes that substantially all
consigned merchandise will be sold in the ordinary course of business before
any purchase obligation is incurred.

Property and Equipment

         Property and equipment are stated at cost.  Depreciation and
amortization are provided on the straight-line method over the following
estimated useful lives.  Energy management equipment is fully depreciated.

</TABLE>

Goodwill

         Goodwill represents the excess cost of companies acquired over the
fair value of their tangible assets.  Goodwill is being amortized on a
straight-line basis over 10-40 years.  The carrying value of goodwill is
reviewed if the facts  and circumstances suggest that it may be impaired.  If
this review indicates that goodwill will not be recoverable, as determined
based on the undiscounted cash flows of the entity acquired over the remaining
amortization period, the Company's carrying value of the goodwill will be
reduced by the estimated shortfall of the undiscounted cash flows.

Income Taxes

         The Company and its subsidiaries file a consolidated federal income
tax return.  The Company uses the liability method in accounting for income
taxes.  Under the liability method, deferred tax assets and liabilities  are
determined based on differences between financial reporting and tax bases of
assets and liabilities and are measured using the enacted tax rates and laws
that will be in effect when the differences are expected to reverse.

Earnings Per Share

         Earnings per share are based upon earnings applicable to common shares
and the weighted average number of shares of common stock and dilutive common
stock equivalents (stock options, warrants and other convertible securities)
outstanding.  The primary weighted average number of common and equivalent
shares outstanding was 10,884,495, 10,246,555, and 10,246,555 for 1997, 1996
and 1995, respectively.  The fully diluted weighted average number of common
and equivalent shares outstanding was 10,913,309 for 1997, 10,513,485 for 1996,
and 10,613,038 for 1995.

Stock Options

         In fiscal year 1997, the Company adopted Statement of Financial
Accounting Standards ("SFAS") No. 123 "Accounting for Stock Based
Compensation," which permits the Company to recognize compensation cost related
to stock options using either the intrinsic value method under Accounting
Principles Board ("APB") Opinion No. 25 "Accounting for Stock Issued to
Employees" or the fair value method under SFAS No. 123.  The Company has
elected to continue to follow APB No. 25 in accounting for stock options.

Supplier/Sources of Supply

         The Company currently purchases a majority of its HVACR equipment and
repair parts from two primary suppliers.  The Company has not encountered any
significant difficulty to date in obtaining equipment and repair parts to
support its operations at current or expected near-term future levels.
However, any disruption in these supply sources could have an adverse effect
upon the Company's operations.

Long-Lived Assets

         In fiscal 1997, the Company adopted SFAS No. 121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of."
Impairment losses are recognized when indicators of impairment are present and
the estimated undiscounted cash flows are not sufficient to recover the
carrying amount of the assets.  The impairment loss is measured by comparing
the fair value of the asset to its carrying value.  The effect of adopting SFAS
No. 121 was not material to the consolidated financial statements.

Recently Issued Accounting Standards

         In February 1997, the Financial Accounting Standards Board issued SFAS
No. 128, "Earnings per Share," which specifies the computation, presentation
and disclosure requirements for earnings per share.  SFAS No. 128 is effective
for financial statements for periods ending after December 15, 1997, and
earlier adoption is not permitted.

         SFAS No. 129, "Disclosure of Information about Capital Structure," was
issued in February 1997.  This statement is effective for financial statements
for periods ending after December 15, 1997.

         The Company has not yet determined the impact on the consolidated
financial statements from the initial adoption of these standards.

2  -     Acquisitions

         In January 1997, the Company entered into a Purchase Agreement
("Agreement") pursuant to which it acquired all of the issued and outstanding
capital stock of Lifetime Filter, Inc. ("LFI"), a Texas corporation, and
contemporaneously therewith, LFI acquired all of the assets, and assumed all of
the liabilities, of the O'Leary Family Partnership, Ltd.  ("OFP"), a Texas
limited partnership.  Prior to such transactions, Mr. Richard O'Leary
("O'Leary") was the sole shareholder of both LFI and RGO, Ltd., the general
partner of OFP.  LFI is a manufacturer and distributor of electrostatic air
filters and sells its products directly to HVACR contractors.

         As consideration for such acquisitions, the Company paid $1,280,662 to
O'Leary and OFP, and LFI issued a promissory note to OFP for $1,166,662.  All
of the cash paid by the Company came from a portion of the proceeds of a loan
to the Company from St. James Capital Partners, L.P. (see Note 4).  The
Agreement provides that the purchase price may subsequently be reduced if LFI
fails to sell

a specified dollar volume of filters during 1997.  The excess of the purchase
price over the estimated fair value of the net assets acquired amounted to
$1,241,426, which has been recorded as goodwill and is being amortized over 40
years using the straight-line method.

         Unaudited pro forma results of the Company's operations for the years
ended February 28, 1997 and February 29, 1996, as if the acquisitions of LFI
and OFP had occurred as of the beginning of each of such fiscal years, are as
follows:

</TABLE>

         These pro forma results are presented for comparative purposes only
and include certain adjustments to give effect to interest expense on
acquisition debt, amortization of goodwill and additional depreciation expense
as a result of a step-up in the basis of fixed assets, together with related
income tax effects.  They do not purport to be indicative of the results of
operations which actually would have resulted had the combination occurred on
March 1, 1996 or March 1, 1995, as applicable, or of future results of
operations of the consolidated entities.

         In January 1996, the Company acquired all of the outstanding capital
stock of Ener-Tech Industries, Inc.  ("ETI"), a Tennessee corporation, for
$72,947 cash and $291,789 in notes payable to the sellers (see Note 4).  ETI is
an HVACR distributor specializing in commercial and industrial controls.  In
October 1995, the Company acquired for $75,000 cash all of the outstanding
capital stock of Sweet Georgia Air Supply, Inc. ("SGAS"), a Georgia
corporation.  SGAS was an HVACR distributor in south Georgia.  Immediately
following the acquisition, SGAS was merged into Total Supply, Inc., the
Company's subsidiary doing business in Georgia.  The Company recorded goodwill
of $127,701 in connection with the acquisition of SGAS.  Pro forma results of
operations relating to these fiscal 1996 acquisitions are not presented because
the effects of such acquisitions were not significant.

         Each of the acquisitions was accounted for using the purchase method
of accounting, and the consolidated financial statements include the operating
results of each business from the date of acquisition.

4  -    Debt (continued)

         The Company has a revolving line of credit arrangement with a
commercial bank ("Bank") pursuant to which the Company may borrow up to $8
million, including amounts outstanding under standby letters of credit.
Borrowings are secured by accounts receivable and inventory, and the permitted
amount of outstanding borrowings at any time is limited to specified
percentages of certain accounts receivable and inventory.  Borrowings under the
line of credit bear interest at the prime rate plus  1/2% (9% at February 28,
1997), payable monthly.  Restrictive covenants of the loan agreement prohibit
the Company from paying dividends, prepaying its indebtedness to The Catalyst
Fund, Ltd. ("Catalyst") or incurring other debt without the Bank's consent, and
also require the Company to maintain certain financial ratios.  As of February
28, 1997, the Company had fully utilized its line of credit with $7.4 million
in outstanding borrowings and letters of credit aggregating $600,000 issued to
secure its trade credit line from a supplier.

         The revolving line of credit matures on February 28, 1998.  As a
result of the Company's acquisitions during 1997, the Company  was in violation
of certain financial covenants under the revolving line of credit at February
28, 1997.  The Company has obtained waivers of these debt covenant violations
from the Bank through August 31, 1997.  On May 12, 1997, as amended on June 10,
1997, the Company obtained a firm commitment from the Bank to refinance the
existing $8 million revolving line of credit with a new $18 million revolving
credit facility, including a $1 million sub-facility for letters of credit.
The new revolving credit facility provides for borrowings, at the Company's
option, at either the Bank's prime rate plus  1/2% or LIBOR plus 3.00%.
Borrowings under the new revolving credit facility will be limited to 85% of
eligible accounts receivable and 50% of eligible inventory amounts.  The
Company expects to close on the new revolving credit facility by June 30, 1997.
Accordingly, the Company has classified the $7.4 million outstanding under the
revolving line of credit at February 28, 1997 as long-term debt in the
accompanying consolidated balance sheet because the Company intends that at
least that amount would remain outstanding under the new revolving credit
agreement for an uninterrupted period extending beyond one year from February
28, 1997.

         In connection with its acquisition of LFI in January 1997 (see Note
2), the Company obtained $1.4 million in financing from St. James Capital
Partners, L.P. ("St. James").  The note issued to St. James (the "St. James
Note") bears interest at 10% per annum and has an initial maturity date of
January 24, 1998, which can be extended for one year at the Company's sole
discretion.  The Company may elect to extend the maturity date of the St. James
Note for one year past the initial maturity date, in which case the Company
will be required to issue a warrant for a number of shares of the Company's
common stock equal to 10% of the outstanding  indebtedness,  including
interest, on  the  St.  James Note   with

an exercise price of $1.625 per share of common stock.  The St. James Note is
classified as long-term debt at February 28, 1997 in the accompanying
consolidated balance sheet, because the Company expects to exercise its option
to extend the maturity date to January 24, 1999.  The St. James Note is secured
by certain assets of LFI and by the stock and operating assets of certain of
the Company's other subsidiaries.  St. James has subordinated its security
interests to the Bank and, with respect to certain assets, to Catalyst.  None
of the principal or accrued interest is payable prior to maturity.  The unpaid
balance of the note, including interest, is convertible into common stock of
the Company at $2.40 per share upon demand by St. James at any time during the
term of the loan.  The Company may require St. James to convert the
indebtedness into the Company's common stock at such time as the average price
of the Company's common stock equals or exceeds $3.25 per share for a period of
twenty consecutive business days and the daily average volume of stock traded
during such period equals a specified minimum.  In connection with the
financing, the Company also issued St.  James a warrant to acquire 280,000
shares of the Company's common stock at an exercise price of $1.625 per share
(see Note 7).  The proceeds of the St. James Note were allocated between the
debt and the warrant, resulting in a debt discount of approximately $70,000,
which is being amortized to interest expense over the term of the loan.

         The OFP Note bears interest at the prime rate plus 1% per annum.  The
Note is to be repaid in twelve equal quarterly installments of principal, plus
accrued interest.  The unpaid balance of the OFP Note, together with all
accrued and unpaid interest, is due and payable on December 31, 1999.  The Note
is secured by a first lien on certain production machinery of LFI and the land
and building on which LFI's plant is situated, and by a junior lien on the
accounts receivable and inventory of LFI.  The OFP Note is subordinated to the
Company's indebtedness to the Bank.

         The Company also borrowed funds from the Bank in 1995 to construct a
warehouse and office building that replaced an existing branch facility in the
Houston area.  The note, which has a balance of $379,200 as of February 28,
1997, is being repaid in equal monthly principal installments of $2,400, plus
interest at the prime rate plus 1%, with the unpaid principal balance due at
maturity on April 30, 2000.  The loan is secured by a deed of trust on both the
land and the building.

         The Company also has a term loan facility from the Bank under which
the Company may borrow up to $500,000 for capital expenditures.  Borrowings
under the facility bear interest at the prime rate plus  1/2%, and principal is
to be repaid monthly over an amortization period of 48 months.  During fiscal
1997, the Company borrowed  $130,000 under this facility to purchase land in
Las Vegas  for

the future construction of a new office/warehouse.  The Company also obtained
seller financing for $250,000, which is payable in full in September 1997.

         In 1993, the Company obtained a $1 million loan from Catalyst in
connection with the acquisition of ACR Supply, Inc.  The loan bears interest at
12 1/2% per annum and is secured by the stock and operating assets of certain
of the Company's subsidiaries and an assignment of proceeds from a life
insurance policy on the Company's President.  The loan is being repaid in 60
equal monthly installments of $22,498, including interest, with the final
payment due in May 1999.  In addition, Catalyst received a warrant to purchase
one million shares of the Company's common stock at a price of $.59 per share,
exercisable at any time before May 1999 (see Note 7).  Catalyst has
subordinated its security interests to the Bank.  Covenants of the loan
agreement prohibit dividends and restrict additional borrowings without
Catalyst's consent, and also require the Company to maintain specified
financial ratios.  The Company has obtained amendments of certain covenants in
the Company's loan agreement with Catalyst which cure any non-compliance with
such covenants as of February 28, 1997, and the Company expects to be in
compliance with all covenants during fiscal 1998.

         The notes issued as part of the purchase price of ETI ("ETI Notes")
bear interest at 9% per annum, and are payable in equal quarterly installments,
including interest, to December 2000.  The ETI Notes are unsecured and are
subordinated to the Company's borrowings from the Bank.

         A supplier permitted a subsidiary of the Company to forego payment on
usual terms for certain merchandise purchased and, in 1993, the Company and the
supplier agreed on a repayment schedule such that $650,000 would be repaid in
four annual installments.  The final payment is due in May 1997.  The supplier
has a subordinated security interest in the assets of the subsidiary.

         At February 28, 1997, other debt consists principally of debt assumed
by the Company in connection with its acquisitions during fiscal 1996.  Such
debt was incurred for both working capital and the purchase of capital assets
and includes notes to both individuals and to commercial banks.  Debt
aggregating $66,497 to certain individuals at February 28, 1997 is subordinated
by the lenders to the Company's borrowings from the Bank.

         Based upon the borrowing rates currently available to the Company for
debt instruments with similar terms and average maturities, the carrying value
of long-term debt approximates fair value.

6  -     Income Taxes

         The Company recognizes a tax benefit from a net operating loss
carryforward if it is more likely than not that such benefit will ultimately be
realized.  Such a tax benefit is recorded on the balance sheet as a deferred
tax asset.  To the extent that it cannot be determined that such tax benefit
will more likely than not be realized, a valuation allowance is established
against the deferred tax asset.  The deferred tax asset is classified as
current to the extent that a tax benefit is expected to be realized in the next
fiscal period.

         The income tax benefit for the fiscal year ended February 28, 1997
consists primarily of a change in the valuation allowance offset by a provision
for current state income taxes and federal alternative minimum taxes.  Income
tax expense for the fiscal years ended February 29, 1996 and February 28, 1995
consists principally of current state income taxes and federal alternative
minimum taxes.  The difference between the income tax provision computed at the
statutory federal income tax rate and the financial statement provision for
taxes is summarized below:

         As of February 28, 1997 and February 29, 1996, the Company has net
operating loss carryforwards of approximately $32.7 million and $34.3 million,
respectively, which are available to offset future taxable income.  If unused,
such carryforwards will expire from 2000 to 2007.  In addition, as of February
28, 1997 and February 29, 1996, the Company has investment and research and
development tax credit carryforwards of approximately $1.1 million expiring on
various dates through 2000.  For financial reporting purposes, the Company has
recognized a valuation allowance of $11.7 million and $12.4 million as of

assets related primarily to the loss carryforward and the credit carryforwards.
The decrease in the valuation allowance from February 29, 1996 to February 28,
1997 was principally due to the recognition of net operating loss carryforwards
which had previously not been recognized.  There are no other significant
components of the Company's deferred tax assets and liabilities as of February
28, 1997.

7  -     Stock Option Agreements and Equity Transactions

         Pursuant to an employment contract, the President of the Company was
granted 125,000 shares of the Company's common stock, valued at $125,000,
during fiscal 1997.  The contract also provides that he is to receive options
for up to 425,000 shares of the Company's stock based upon attainment in the
future of certain levels of consolidated net income as defined in the contract.
The exercise price of all options issued thereunder is the market price of the
Company's stock at the time the options are granted.  Of such options, 50,000
(none in fiscal 1997 and 25,000 in fiscal 1996), which expire 25,000 in each of
May 1999 and June 2000, have been granted at an average exercise price of $.77
per share.  Options for 75,000 shares will be granted in fiscal 1998 based upon
the Company's results of operations in fiscal 1997.  The President also holds
options to purchase 8,437 shares at $.13 per share that expire in August 1997,
and 325,000 shares at $.49 per share that expire in February 1998.  All such
options granted are currently exercisable.

         In connection with its financing provided to the Company, St. James
Capital Partners, L.P. ("St. James") received a warrant to acquire 280,000
shares of the Company's common stock at an exercise price of $1.625 per share,
exercisable at any time before January 2002.  In connection with its loan to
the Company, the Catalyst Fund, Ltd.  ("Catalyst") received a warrant to
purchase one million shares of the Company's common stock at a price of $.59
per share, exercisable at any time before May 1999.  See Note 4.  During 1997,
Catalyst sold 250,000 of such warrants to St. James.

         In March 1994, the Company entered into an employment contract with
the general manager of a subsidiary and concurrently awarded him options to
purchase 25,000 shares of common stock at $.55 per share that expire in
February 1999.  Pursuant to his contract, which expired at the end of February
1997, the Company awarded him options in fiscal 1996 to purchase 15,000 shares
at $.70 per share which expire in April 2000.  All such options granted are
currently exercisable.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                 (CONTINUED)




7  -     Stock Option Agreements and Equity Transactions (continued)

         In fiscal 1997, the Company established the 1996 stock option plan for
key employees and directors of the Company and its subsidiaries.  The plan
provides for the granting of non-qualified stock options and/or incentive stock
options.  No options were granted in fiscal 1997 and 500,000 shares of common
stock were available for future grants at February 28, 1997.

         Pro forma information regarding net income and earnings per share is
required by SFAS No. 123, and has been determined as if the Company had
accounted for its employee stock options under the fair value method of SFAS
No. 123.  The fair value for these options was estimated at the date of grant
using a Black-Scholes option pricing model.  Based upon the Company's
calculations, net income and earnings per share, using this fair value method,
would not be materially different from the amounts reported.  The weighted
average fair value of options granted during 1996 was $0.33.

8  -     Profit Sharing Plan

         The Company has a qualified profit sharing plan ("Plan") under Section
401(k) of the Internal Revenue Code.  The Plan is open to all eligible
employees.  The Company matches 50% of the participant's contributions, not to
exceed 3% of each participant's compensation.  Company contributions to the
Plan were $111,609, $94,247 and $71,986 for fiscal 1997, 1996 and 1995,
respectively.

9  -     Subsequent Events

         In April 1997, the Company acquired for approximately $70,000 the
assets and liabilities of ACH Supply, Inc.  ("ACH"), a wholesale distributor of
HVACR products with two branches in the Los Angeles area.  ACH had sales of
$2.8 million for its fiscal year ended June 30, 1996.  In April 1997, the
Company also borrowed an additional $450,000 from Catalyst, the proceeds of
which were used principally to provide working capital for ACH.  The payment
terms and the interest rate of the additional borrowings are substantially the
same as for the Company's previously existing loan from Catalyst (see Note 4).

         In May 1997, the Company entered into a letter of intent to acquire
the operating assets and related liabilities of Contractors Heating & Supply,
Inc. ("CHS"), a Denver-based HVACR distributor with three branches in Colorado
and one in New Mexico.  CHS had sales of approximately $20 million for the year
ended December 31, 1996.  The purchase price of the assets and liabilities of
CHS is estimated at $6 million, of which $4.8 million will be borrowed from the
Bank under the new revolving credit facility (see Note 4), and $1.2 million
will be financed by the seller.  The Company expects to conclude the
acquisition of CHS in the second quarter of fiscal 1998.

                                ACR GROUP, INC.

               WARRANT FOR THE PURCHASE OF SHARES OF COMMON STOCK

         No. 4                                                   750,000 Shares

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

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

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

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





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

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

         5.      CERTAIN ADJUSTMENTS.

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

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





                                       3

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

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

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

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

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





                                       4

                          Common Stock covered thereby;

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

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

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

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

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

                          (D)     Excluded Stock. "Excluded Stock" shall mean
                 (1) up to 200,000 shares of Common Stock to be issued from
                 time to time to directors, officers, employees, consultants,
                 advisors, independent contractors and agents of the Company
                 pursuant to stock options, employee benefit plans or otherwise
                 together with any such shares that are repurchased by the
                 Company and reissued to any such recipient, (2) shares of
                 Common Stock to be issued from time to time pursuant to stock
                 options granted by the Company prior to April 14, 1997, (3)
                 up to 25,985 shares of Common Stock to be to A. Stephen
                 Trevino, (4) up to 550,000 shares of Common Stock which may be
                 issued to Alex Trevino, Jr. pursuant to that certain
                 employment agreement entered into between the Company and Alex
                 Trevino, Jr. dated as of May 17, 1993, (5) up to 500,000
                 shares of Common Stock to be issued from time to time pursuant
                 to the 1996 Stock Option Plan of the Company, (6) up to
                 1,000,000 shares of Common Stock to be issued pursuant to
                 warrants Issued by the Company to St. James Capital Partners,
                 L.P., a Delaware limited partnership ("St. James"), or its
                 assigns, and (7) shares of Common Stock to be issued to St.
                 James, or its assigns, pursuant to private placement purchases
                 by St. James of either Common Stock or debt instruments of the
                 Company which are convertible into Common Stock, in an
                 aggregate amount not to exceed $5,000,000. All shares of
                 Excluded Stock that the Company has reserved for issuance
                 shall be deemed to be outstanding for all purposes of
                 computations under this Section 5(b).

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

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

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

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





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

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

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

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

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




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

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

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

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





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

         7.      PUT OPTIONS.

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





                                       10
<PAGE>   11
         hereunder to the Company.

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





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

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

         8. CERTAIN CORPORATE EVENTS OR ACTIONS.

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

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





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

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

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

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

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

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





                                       13
<PAGE>   14
interest on the Notes is fully repaid prior to August 26, 2001, then the
expiration date of this Warrant shall expire thirty (30) days after the date of
such payment; provided, however, that under no circumstances shall the
expiration date be earlier than May 26, 1999; and further provided that if the
date of the complete payment of all of the Notes is during the time period of
April 27, 1999 through May 26, 1999, then the Warrant expiration date shall
occur thirty (30) days after such payment date. Additionally, if the Holder has
exercised any put option under Section 7 of this Agreement and (a) the Company
is financially unable, or in any event fails, to timely pay all of the required
purchase price under Section 7, or (b) or any creditor of the Company has
indicated to the Holder or the Company that the payment of such required
purchase price would be a default under the Company's indebtedness to such
creditor, then the expiration date of this Warrant shall be extended to the
date that is three and one-half years beyond the then expiration date of this
Warrant for any portion of this Warrant not purchased by the Company (including
any portion of this Warrant that the Holder has not required the Company to
purchase under Section 7), and the Holder shall be deemed to have retracted its
exercise of such put option; provided, however, that such retraction shall be
without prejudice to the Holder, and the Holder shall be entitled, at any time
thereafter prior to the expiration of this Warrant, to re-exercise such put
option upon the same term is of the prior exercise thereof upon the terms and
conditions set forth in Section 7.

         11.     CERTAIN NOTICES. In case at any time the Company shall propose

         Shares of Common Stock or to fix a record date for the making of any
         such dividend or distribution to holders of Common Stock; or

                 (b) to take, or fix a record date for, any action that would
         result in any adjustment to the Exercise Price pursuant to Section 5;
         or

         outstanding Shares of Common Stock, or consolidation or merger, or
         sale, lease or conveyance of property, of the type addressed in
         Section 8; or

                 (d)      to effect any voluntary or involuntary liquidation,
dissolution or winding up of the Company;

then, and in any one or more of such cases, the Company shall give written
notice thereof to the Holder at least 30 days prior to the date on which (i)
the books of the Company shall close or a record date shall be set, for any
such action described in Section 11 (a) or (b) or (ii) such reclassification,
change, consolidation, merger, sale, lease, conveyance, liquidation,
dissolution or winding-up shall be effective, as the case may be.

         13.     RESTRICTIONS ON TRANSFER. This Warrant and the Shares of
Common Stock or other securities issued upon exercise of this Warrant shall be
subject to a stop-transfer order (except with respect to a transfer by the
original Holder of this Warrant to its partners) and the certificate or
certificates evidencing any such Shares or securities shall bear the following
legend, unless in the opinion Of counsel to the Holder exercising any Warrant
such legend is not required in order to comply with the Securities Act of 1933,
as amended (the "Securities Act"), which opinion shall be reasonably
satisfactory to the Company, or unless the offering and sale of the Shares or
other securities issued upon exercise of the Warrants have been registered
under the Securities Act, and in each such case such restriction on transfer
and legend shall be removed:

         "THE SHARES (OR OTHER SECURITIES) REPRESENTED BY THIS CERTIFICATE HAVE
BEEN ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
ACT OF 1933, AS AMENDED, OR THE SECURITIES LAWS OF ANY STATE OR OTHER
JURISDICTION. SUCH SECURITIES MAY NOT BE SOLD, ASSIGNED OR OTHERWISE
TRANSFERRED EXCEPT UPON SUCH REGISTRATION OR UPON DELIVERY TO THE CORPORATION

         14.     REGISTRATION OF COMMON STOCK, LISTING. If any Shares of Common
Stock required to be reserved for purposes of exercise of this Warrant required
registration with or approval of any governmental authority under any federal
or state law before such Shares may be issued upon exercise, the Company will,
at its expense and as expeditiously as possible, cause such Shares to be duly
registered or approved, as the case may be. At any such time as Common Stock is
listed for trading, the Company will, at its expense, obtain promptly and
maintain the approval of all securities exchanges (including, for this purpose,
NASDAQ and the NASDAQ National Market System) on which the Common Stock is
listed for trading for an additional listing, upon official notice of issuance,
of the Shares of Common Stock issuable upon exercise of the then outstanding
Warrants and maintain the listing of such shares after their issuance.

filed a registration statement pursuant to Section 12 of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), or a registration
statement pursuant to the Securities Act, the Company will comply with the
reporting requirements of Sections 13 and 15(d) of the Exchange Act (or, if the
Company is not required to so comply and it shall have so filed such a
registration statement, it will make publicly available the information

availability of an exemption from the Securities Act for the sale of any
restricted securities (as defined in the Securities Act) or the sale of
securities by affiliates (as defined in the Securities Act). The Company will
also cooperate with each holder of any restricted securities in supplying such
information as may be necessary for such holder to

stock exchange or any other industry self-regulating body (referred to
collectively for purposes in this Section 15(b) as "Law"), the Holder will not
disclose, publish or reveal any of the Information except to those of its
employees, agents or representatives as have a need to know and who have

representatives who have access to the Information, that the United States
securities laws may prohibit any Person who has received material, non-public
information with respect to an issuer from purchasing or selling securities of
such issuer or from communicating such information to any other Person. The
responsibility of the Holder with respect to Information received from Company
and/or its subsidiaries shall terminate as to such of the Information as
becomes public knowledge by publication or general knowledge in the trade
through no fault of the Holder, its employees, agents or representatives.

substance of the lost, stolen, destroyed or mutilated Warrant (including all
changes and adjustments that have occurred hereunder).

         17.     NO RIGHTS OR LIABILITIES AS A STOCKHOLDER. Nothing contained
in this Warrant shall be construed as conferring upon the Holder hereof any
rights as a stockholder of the Company or as imposing any obligation upon such
Holder to purchase any securities or as imposing any liability upon such Holder
as a stockholder of the Company, whether such obligation or liability is
asserted by the Company or by creditors of the Company at law or in equity.

the Holder of this Warrant in the event of any default or threatened default by

Warrant are not and will not be adequate, and that, to the extent permitted by
applicable law, such terms may be specifically enforced by a decree for the
specific performance of any agreement contained herein or by an injunction
against a violation of any of the terms hereof or otherwise; provided, however,

this Warrant unless the Holder is acting in contravention of its obligations or
outside of its rights under this Warrant and (ii) the Company hereby agrees to
indemnify and hold harmless the Holder from any costs, liabilities, losses or
expenses incurred by the Holder caused by or otherwise associated with a claim
by the Company for specific enforcement of its rights under this Warrant if
such claim is not a claim permitted to be made pursuant to clause (i)
immediately preceding.

herein shall be delivered or mailed by registered or certified mail, return

signed by the party against which enforcement of such change, waiver, discharge
or termination is sought. Any provision of this Warrant that shall be
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,

         THE WARRANT REPRESENTED HEREBY AND THE SECURITIES ISSUABLE UPON
EXERCISE HEREOF HAVE BEEN ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED
UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR THE SECURITIES LAWS OF ANY

                                ACR GROUP, INC.

               WARRANT FOR THE PURCHASE OF SHARES OF COMMON STOCK

No. 5                                                            250,000 Shares

         BY THIS WARRANT (this "Warrant"), ACR Group, Inc., a Texas corporation
(the "Company"), certifies that, for good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, St. James Capital
Partners, L.P., a Delaware limited partnership (along with its registered
assigns, the "Holder"), is entitled to subscribe for and purchase from the
Company, subject to the terms and conditions set forth herein, at any time on
or after the date hereof but prior to 5:00 p.m. (Houston, Texas time) on May
26, 1999, unless otherwise extended as provided herein, or, if such date is not
a business day, the next succeeding business day (the "Exercise Period"),
250,000 (subject to adjustment as set forth herein) fully paid and
non-assessable shares (the "Shares") of the Company's Common Stock, $.01 par
value per share (the "Common Stock"), at a price equal to the exercise price
per share, initially $.58594 (subject to adjustment as set forth herein) per
share (the "Exercise Price").

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

         2.      STOCK OWNERSHIP; STOCK CERTIFICATES; PARTIAL EXERCISE. Upon
each exercise of this Warrant, the Holder shall be deemed to be the holder of
record of the Shares of Common Stock issuable upon such exercise,
notwithstanding that the stock transfer books of the Company shall then be
closed or certificates representing such Shares shall not then have been
actually

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

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





                                       2
<PAGE>   3
Warrant, or other Warrants, of different denominations and representing in the
aggregate the right to purchase the same number of Shares of Common Stock on
the terms and conditions set forth herein (including all changes and
adjustments that have occurred hereunder) upon surrender to the Company or its
duly authorized agent. All provisions of this Section 3 shall be subject to
Section 13.

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

         5.      CERTAIN ADJUSTMENTS.

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

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

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

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

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

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

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





                                       4
<PAGE>   5
                          (2)     the aggregate maximum number of shares of
                 Common Stock deliverable upon conversion of or in exchange for
                 any such convertible or exchangeable securities, or upon the
                 exercise of options, warrants or other rights to purchase or
                 acquire such convertible or exchangeable securities and the
                 subsequent conversion or exchange thereof, shall be deemed to
                 have been issued at the time such securities were issued or
                 such options, warrants, or rights were issued and for a
                 consideration equal to the consideration, if any, received by
                 the Company for any such securities and related options,
                 warrants or rights (excluding any cash received on account of
                 accrued interest or accrued dividends), plus the additional
                 consideration (determined in the manner provided in subclauses
                 (A) and (B) above), if any, to be received by the Company upon
                 the conversion or exchange of such securities, or upon the
                 exercise of any related options, warrants or rights to
                 purchase or acquire such convertible or exchangeable
                 securities and the subsequent conversion or exchange thereof;

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





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

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

                 (D)      Excluded Stock. "Excluded Stock" shall mean (1) up to
         200,000 shares of Common Stock to be issued from time to time to
         directors, officers, employees, consultants, advisors, independent
         contractors and agents of the Company pursuant to stock options,
         employee benefit plans or otherwise together with any such shares that
         are repurchased by the Company and reissued to any such recipient, (2)
         shares of Common Stock to be issued from time to time pursuant to
         stock options granted by the Company prior to May 26, 1993, (3) up to
         25,985 shares of Common Stock to be issued to A. Stephen Trevino, and
         (4) up to 550,000 shares of Common Stock which may be issued to Alex
         Trevino, Jr. pursuant to that certain employment agreement entered
         into between the Company and Alex Trevino, Jr. dated as of May 17,
         1993, (5) up to 500,000 shares of Common Stock to be issued from time
         to time pursuant to the 1996 Stock Option Plan of the Company, (6) up
         to 1,000,000 shares of Common Stock to be issued pursuant to warrants
         issued by the Company to St. James Capital Partners, L.P., a Delaware
         limited partnership ("St. James"), or its assigns, and (7) shares of
         Common Stock to be issued to St. James, or its assigns, pursuant to
         private placement purchases by St. James of either Common Stock or
         debt instruments of the Company which are convertible into Common
         Stock, in an aggregate amount not to exceed $5,000,000. All shares of
         Excluded Stock that the Company has reserved for issuance shall be
         deemed to be outstanding for all purposes of computations under this
         Section 5(b).





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

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

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





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

                 (f)      Size of Adjustment; Rounding. No adjustment in the
         Exercise Price shall be required unless such adjustment would require
         an increase or decrease of at least one. cent ($.0l) in such price;
         provided, however, that any adjustment that is thereby not required to
         be made shall be carried forward and taken into account in any
         subsequent adjustment. All calculations under this Section 5 shall be
         made to the nearest cent or to the nearest one-hundredth of a Share,
         as the case may be.

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

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

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





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

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

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

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





                                       9
<PAGE>   10
of any such notice to agree to purchase up to its pro rata share of such New
Securities for the price and upon the terms specified in the notice by giving
written notice to the Company and stating therein the quantity of New
Securities to be purchased. In the event the Holder fails to exercise such
right of purchase within said 30-day period, the Company shall have 90 days
thereafter to complete the sale of the New Securities at the price and upon
terms no more favorable to the purchasers of such New Securities than those
specified in the Company's notice to the Holder. In the event the Company has
not sold the New Securities within such 90-day period, the Company shall not
thereafter issue or sell any of such New Securities without first complying
with the terms of this Section 6.

         7.      PUT "OPTIONS.

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





                                       10
<PAGE>   11
         with the terms and procedures set forth above. This option shall be a
         continuing option, exercisable as many times as the Holder shall
         choose, and shall continue and remain until the Holder has sold all
         unissued Shares of Common Stock evidenced by this Warrant and all
         Shares of Common Stock issued hereunder to the Company.

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





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

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

         8.      CERTAIN CORPORATE EVENTS OR ACTIONS.

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





                                       12
<PAGE>   13
                 (b)      Reclassification, Etc. In case of any
         reclassification or change of the Shares of Common Stock issuable upon
         exercise of this Warrant or in case of any consolidation or merger or
         another corporation or other entity with or into the Company in which
         the Company is the continuing corporation (other than as a subsidiary
         of another corporation or other entity) and in which there is a
         reclassification or change (including a change to the right to receive
         cash or other property) of the Shares of Common Stock, the Holder
         shall have the right thereafter to receive upon exercise of this
         Warrant the kind and amount of shares of stock and other securities,
         property, cash or any combination thereof receivable upon such
         reclassification, change, consolidation or merger by a holder of the
         number of Shares of Common Stock into which this Warrant would have
         been exercisable immediately prior to such reclassification, change,
         consolidation or merger. Thereafter, appropriate provision (as
         determined by the Board of Directors of the Company in good faith)
         shall be made for adjustments which shall be equivalent to the
         adjustments in Section 5.

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

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

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

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

         10.     EXTENSION OF EXPIRATION DATE. If the last scheduled payment
date for the repayment of outstanding indebtedness under any of those certain
promissory notes (the "Notes"), each dated May 26, 1993 executed by ACR Supply,
Inc., a Texas corporation, Fabricated Systems, Inc., a Texas corporation, and
Heating and Cooling Supply, Inc., a Nevada corporation, and payable to the order
of The Catalyst Fund, Ltd., a Texas limited partnership,





                                       13
<PAGE>   14
in the aggregate original principal amount of $1,000,000 shall be extended
beyond May 26, 1999, then the expiration date of this Warrant shall also be
likewise extended to the date that is equal to the latest of the last scheduled
payment dates under any of the Notes. Additionally, if the Holder has exercised
any put option under Section 7 of this Agreement and (a) the Company is
financially unable, or in any event fails, to timely pay all of the required
purchase price under Section 7, or (b) or any creditor of the Company has
indicated to the Holder or the Company that the payment of such required
purchase price would be a default under the Company's indebtedness to such
creditor, then the expiration date of this Warrant shall be extended to the
date that is three and one-half years beyond the then expiration date of this
Warrant for any portion of this Warrant not purchased by the Company (including
any portion of this Warrant that the Holder has not required the Company to
purchase under Section 7), and the Holder shall be deemed to have retracted its
exercise of such put option; provided, however, that such retraction shall be
without prejudice to the Holder, and the Holder shall be entitled, at any time
thereafter prior to the expiration of this Warrant, to re-exercise such put
option upon the same terms of the prior exercise thereof upon the terms and
conditions set forth in Section 7.

         11. CERTAIN NOTICES. In case at any time the Company shall propose or
have knowledge of any proposal:

                 (a)      to pay any dividend or make any distribution on
         Shares of Common Stock or to fix a record date for the making of any
         such dividend or distribution to holders of Common Stock; or

                 (b) to take, or fix a record date for, any action that would
         result in any adjustment to the Exercise Price pursuant to Section 5;
         or

                 (c)      to effect any reclassification or change of
         outstanding Shares of Common Stock, or consolidation or merger, or
         sale, lease or conveyance of property, of the type addressed in
         Section 8; or

                 (d)      to effect any voluntary or involuntary liquidation,
         dissolution or winding-up of the Company;

then, and in any one or more of such cases, the Company shall give written
notice thereof to the Holder at least 30 days prior to the date on which (i)
the books of the Company shall close, or a record date shall be set, for any
such action described in Section 11 (a) or (b) or (ii) such reclassification,
change, consolidation, merger, sale, lease, conveyance, liquidation,
dissolution or winding-up shall be effective, as the case may be.

         12.     EXPENSES. The Company shall pay all costs, fees, taxes (other

<PAGE>   15
         13.     RESTRICTIONS ON TRANSFER. This Warrant and the Shares of
Common Stock or other securities issued upon exercise of this Warrant shall be
subject to a stop-transfer order (except with respect to a transfer by the
original Holder of this Warrant to its partners) and the certificate or
certificates evidencing any such Shares or securities shall bear the following
legend, unless in the opinion of counsel to the Holder exercising any Warrant
such legend is not required in order to comply with the Securities Act of 1933,
as amended (the "Securities Act"), which opinion shall be reasonably
satisfactory to the Company, or unless the offering and sale of the Shares or
other securities issued upon exercise of the Warrants have been registered
under the Securities Act, and in each such case such restriction on transfer
and legend shall be removed:

"THE SHARES (OR OTHER SECURITIES) REPRESENTED BY THIS CERTIFICATE HAVE BEEN
ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT
OF 1933, AS AMENDED, OR THE SECURITIES LAWS OF ANY STATE OR OTHER JURISDICTION.
SUCH SECURITIES MAY NOT BE SOLD, ASSIGNED OR OTHERWISE TRANSFERRED EXCEPT UPON
SUCH REGISTRATION OR UPON DELIVERY TO THE CORPORATION OF AN OPINION OF COUNSEL
REASONABLY SATISFACTORY TO THE CORPORATION STATING THAT SUCH SALE, ASSIGNMENT
OR TRANSFER IS EXEMPT FROM REGISTRATION UNDER SUCH ACT AND LAWS."

         14.     REGISTRATION OF COMMON STOCK; LISTING. If any Shares of Common
Stock required to be reserved for purposes of exercise of this Warrant require
registration with or approval of any governmental authority under any federal
or state law before such Shares may be issued upon exercise, the Company will,
at its expense and as expeditiously as possible, cause such Shares to be duly
registered or approved, as the case may be. At any such time as Common Stock is
listed for trading, the Company will, at its expense, obtain promptly and
maintain the approval of all securities exchanges (including, for this purpose,
NASDAQ and the NASDAQ National Market System) on which the Common Stock is
listed for trading for an additional listing, upon official notice of issuance,
of the Shares of Common Stock issuable upon exercise of the then outstanding
Warrants and maintain the listing of such shares after their issuance.

         15.     AVAILABILITY OF INFORMATION. (a) If the Company shall have
filed a registration statement pursuant to Section 12 of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), or a registration
statement pursuant to the Securities Act, the Company will comply with the
reporting requirements of Section 13 and 15(d) of the Exchange Act (or, if the
Company is not required to so comply and it shall have so filed such a
registration statement, it will make publicly available the information
specified by Rule 144(c)(2) under the Securities Act) and will comply with all
other public information reporting requirements of the Securities and Exchange
Commission (the "Commission") (including Rule 144 promulgated by the Commission
under the Securities Act) from time to time in effect and relating to the
availability of an exemption from the Securities Act for the sale of any
restricted securities (as defined in the Securities Act) or the sale of
securities by affiliates (as defined in the Securities Act). The Company will
also cooperate with each holder of any restricted securities in supplying such





                                       15
<PAGE>   16
information as may be necessary for such holder to complete and file any
information reporting forms presently or hereafter required by the Commission
as a condition to the availability of an exemption from the Securities Act for
the sale of any restricted securities or the sale of securities by affiliates.
The Company will furnish to each Holder of a Warrant, promptly upon their
becoming available, copies of all financial statements, reports, notices and
proxy statements sent or made available generally by the Company to its
stockholders, and copies of all regular and periodic reports and all
registration statements and prospectuses filed by the Company with any
securities exchange or with the Commission. The Company will also furnish each
Holder with copies of all minutes of all meetings of the Company's Board of
Directors or any committee thereof, forthwith after such minutes have been
prepared.

         (b)     The Holder agrees to accept and maintain on a confidential
basis as Provided in this Section 15(b), all information obtained by it
pursuant to Section 15(a) or otherwise under this Agreement (such information
is referred to for purposes of this Section 15(b) as "Information"). The Holder
agrees that unless it receives the express written permission of the Company or
is otherwise required to make disclosure by law, a regulation of a national
stock exchange or any other industry self-regulating body (referred to
collectively for purposes in this Section 15(b) as "Law"), the Holder will not
disclose, publish or reveal any of the Information except to those of its
employees, agents or representatives as have a need to know and who have agreed
to maintain the confidentiality of the Information. Except as may be required
by Law, the Holder will not disclose any of the Information to third parties.
The Holder agrees, and it will advise all employees, agents and representatives
who have access to the Information, that the United States securities laws may
prohibit any Person who has received material, non-public information with
respect to an issuer from purchasing or selling securities of such issuer or
from communicating such information to any other Person. The responsibility of
the Holder with respect to Information received from Company and/or its
subsidiaries shall terminate as to such of the Information as becomes public
knowledge by publication or general knowledge in the trade through no fault of
the Holder, its employees, agents or representatives. Notwithstanding anything
to the contrary in this Section 15(b), the Holder may, (i) with respect to any
prospective purchaser of the Warrant (or any portion thereof) that is not a
direct competitor of the Company or any of its subsidiaries (each such
prospective purchaser being hereinafter referred to as a "Company Competitor"),
after written notice to the Company on or before the 10th day prior to
disclosure, disclose Information to any such prospective purchaser; provided,
however, that the Holder may immediately disclose Information to any such
Person upon the occurrence and continuance of any Event of Default (as such
term is defined in that certain Note Agreement of even date herewith to which
the Company and the Holder are parties (among other parties) (the "Note
Agreement"); (ii) with respect to any prospective purchaser of the Warrant (or
any portion thereof) that is a Company Competitor, upon the occurrence and
continuance of any Event of Default (as such term is defined in the Note
Agreement), disclose Information to any such prospective purchaser; (iii)
disclose Information to the Holder's legal counsel or auditors, so long as such
disclosures are held in confidence by the recipients thereof; and (iv) so long
as The Catalyst Fund, Ltd. is a Person constituting the Holder, disclose
information to any Person who is an equity investor in The Catalyst Fund, Ltd.

         16.     LOSS, THEFT, ETC. Upon receipt of evidence satisfactory to the
Company of the loss, theft, destruction or mutilation of any Warrant and upon
surrender and cancellation of any Warrant if mutilated, the Company shall
execute and deliver to the Holder thereof a new Warrant in the form and
substance of the lost, stolen, destroyed or mutilated Warrant (including all
changes and adjustments that have occurred hereunder).

         17.     NO RIGHTS OR LIABILITIES AS A STOCKHOLDER. Nothing contained
in this Warrant shall be construed as conferring upon the Holder hereof any
rights as a stockholder of the Company or as imposing any obligation upon such
Holder to purchase any securities or as imposing any liability upon such Holder
as a stockholder of the Company, whether such obligation or liability is
asserted by the Company or by creditors of the Company at law or in equity.

         18.     GOVERNING LAW. This Warrant shall be governed by and construed
in accordance with the internal laws of the State of Texas.

         19.     REMEDIES. The Company stipulates that the remedies at law of
the Holder of this Warrant in the event of any default or threatened default by
the Company in the performance of or compliance with any of the terms of this
Warrant are not and will not be adequate, and that, to the extent permitted by
applicable law, such terms may be specifically enforced by a decree for the
specific performance of any agreement contained herein or by an injunction
against a violation of any terms hereof or otherwise; provided, however, that
(i) the Company shall not seek specific enforcement of its rights under this
Warrant unless the Holder is acting in contravention of its obligations or
outside of its rights under this Warrant and (ii) the Company hereby agrees to
indemnify and hold harmless the Holder from any costs, liabilities, losses or
expenses incurred by the Holder caused by or otherwise associated with a claim
by the Company for specific enforcement of its rights under this Warrant if
such claim is not a claim permitted to be made pursuant to clause (i)
immediately preceding.

         20.     NOTICES. All notices and other communications provided for
herein shall be delivered or mailed by registered or certified mail, return
receipt requested, postage prepaid, addressed (a) if to any Holder of any
Warrant, to the address of such Holder as set forth in the Warrant Register or
to such other address as such Holder has notified the Company of in writing, or
(b) if to the Company, to the address set forth in Section 1 or to such other
address as the Company has notified such Holder of pursuant to Section I and
this Section 20; provided, however, that the exercise of any Warrant shall be
effective in the manner provided in Section 1. All notices given pursuant to
this Warrant shall be deemed to be effective upon receipt thereof by the party
to whom such notice is addressed.

signed by the party against which enforcement of such change, waiver, discharge
or termination is sought. Any provision of this Warrant that shall be

                                   ARTICLE II

                    REPRESENTATIONS AND WARRANTIES OF SELLER

         Seller represents and warrants to the Purchaser as follows:

         2.1     Organization, Standing, and Qualification.  Seller is a
corporation duly organized, validly existing and in good standing under the
laws of the State of Texas and has all requisite corporate power and authority
to own, lease and operate its properties and to carry on its business as it is
now being conducted.  Seller is licensed and qualified to do business as a
foreign corporation in each jurisdiction in which the character of Seller's
properties, owned or leased, or the nature of its activities makes such
qualification or license necessary, except where failure to be so licensed and
qualified would not have a material adverse effect on Seller's business.

         2.2     Authority; No Defaults.  Seller has all requisite corporate
power and authority to enter into the Transaction Documents and to consummate
the transactions contemplated thereby.  The execution and delivery of the
Transaction Documents and the consummation of the transactions contemplated
thereby have been duly authorized by all necessary corporate action on the part
of Seller.  The Transaction Documents have been executed and delivered by
Seller and constitute the valid and binding obligation of Seller, enforceable
in accordance with their terms, subject to bankruptcy, insolvency, moratorium
and other similar laws affecting creditors' rights generally and general
principles of equity (regardless of whether such enforceability is considered
in a proceeding in equity or at law).  The execution and delivery of the
Transaction Documents do not, and the consummation of the transactions
contemplated hereby and thereby will not, conflict with or result in a breach
of or the acceleration of any obligation under, or constitute a default or
event of default (or event which, with notice or lapse of time or both, would
constitute a default) under, any provision of any charter, bylaw, indenture,
mortgage, lien, lease, agreement, contract, instrument, order, judgment,
decree, ordinance or regulation, or any restriction to which any property of
Seller is subject or by which Seller is bound, the effect of which would be
materially adverse to Seller.  Seller is not, nor is it alleged to be, in
material violation or default of any applicable law, statute, order, rule or
regulation promulgated or judgment entered by any court, administrative agency
or commission or other governmental agency or instrumentality, domestic or
foreign (a "Governmental Entity"), relating to or affecting the operation,
conduct or ownership of the property or business of Seller.

         2.3     Approvals.  There is no legal impediment to the execution and
delivery of the Transaction Documents by Seller or to the consummation of the
transactions contemplated thereby, and no filing or registration with, or
authorization, consent or approval of, a Governmental Entity, shareholders or
any other third party is necessary for the consummation by Seller of the
transactions contemplated thereby.

         2.4     SEC Documents.  Seller has made all filings with the
Securities and Exchange Commission ("SEC") that it has been required to make
under the Securities Act of 1933, as amended (the "Securities Act"), and the
Securities Exchange Act of 1934, as amended (the "Exchange Act") since February
28, 1995.  Seller has provided to the Purchaser a true, complete and correct
copy of Seller's





                                       2
<PAGE>   3
annual report on Form 10-K for the fiscal year ended February 29, 1996 together
with all amendments thereto, and any and all filings with the SEC made by
Seller (including all requested exhibits to such filings) since the filing of
said Form 10-K (all such documents that have been filed with the SEC, as
amended, are referred to as the "Seller SEC Documents").  As of their
respective dates, and except as amended, the Seller SEC Documents complied in
all material respects with the requirements of the Securities Act or the
Exchange Act, as the case may be, and none of the Seller SEC Documents
contained any untrue statement of a material fact or omitted to state a
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading.  The financial statements of Seller included in the Seller SEC
Documents comply as to form in all material respects with applicable accounting
requirements and with the published rules and regulations of the SEC with
respect thereto, have been prepared in accordance with generally accepted
accounting principles ("GAAP") applied on a consistent basis during the periods
involved (except as may be indicated in the notes thereto or, in the case of
the unaudited statements, as permitted by Form 10-Q) and fairly present
(subject, in the case of the unaudited statements, to normal recurring audit
adjustments) the consolidated financial position of Seller as of the dates
thereof and the consolidated results of its operations and cash flows for the
periods then ended.  Except as set forth in the Seller SEC Documents, since
November 30, 1996, (i) there have been no material adverse changes in the
Seller's business, operations or financial condition and (ii) Seller's
operations have been conducted in the ordinary course of business except as
disclosed in writing to the Purchaser.

         2.5     Litigation.  Except as set forth in Seller SEC Documents, as
of the date of this Agreement, there is no suit, action, proceeding or
investigation pending or, to the best knowledge of Seller, threatened against
or affecting Seller (or any of its respective officers or directors in
connection with the business of Seller), nor is there any outstanding judgment,
order, writ, injunction or decree against Seller, which judgment would have a
material adverse effect on Seller.  Seller is not subject to any court order,
writ, injunction, decree, settlement agreement or judgment that contains or
orders any on-going obligations, whether prohibitory or mandatory in nature,
the performance of which would have a material adverse effect on Seller.

         2.6     Capitalization.  Seller has authorized capital stock of (a)
25,000,000 shares of Common Stock of which there are 10,371,555 shares issued
and outstanding, and (b) 2,000,000 shares of preferred stock, par value $.0l
per share, ("Preferred Stock"), of which none are issued and outstanding.  All
of the issued and outstanding shares of Common Stock were duly and validly
issued and are fully paid and non-assessable.  None of the outstanding shares
of Common Stock have been issued in violation of any preemptive rights of the
current or past shareholders of Seller.  As of the date hereof, the Seller has
reserved for issuance (i) an aggregate of 923,437 shares of Common Stock
issuable on issuance of stock options to employees, officers and directors,
(ii) an aggregate of 1,000,000 shares of Common Stock issuable on issuance of
stock options and warrants to persons other than those described above in (i),
and (iii) no shares of Common Stock are issuable on exercise of convertible
securities other than those listed in (i) and (ii) above.  Except as set forth
on Schedule 2.6, or described above in (i), (ii) and (iii), and except for
shares that may be issued in connection with completed or pending acquisitions,
there are no outstanding options, warrants or rights to subscribe for, or
commitments of any character whatsoever relating to, or securities or rights
convertible into or exchangeable for, shares of the capital stock of Seller or
contracts, commitments, understandings or arrangements by which Seller is or
may be obligated to issue additional shares of its capital stock or options,
warrants, or rights to purchase or acquire any additional shares of its capital
stock.  All of the Common Stock issued on the conversion of the Note and the
exercise of the Warrants will be fully paid, non-assessable and free and clear
of any preemptive rights and Encumbrances.  As used in this Agreement, the term
"Encumbrance" means and includes (i) any





                                       3
<PAGE>   4
security interest, mortgage, deed of trust, lien, charge, pledge, proxy,
adverse claim, equity, power of attorney, or restriction of any kind, including
but not limited to, any restriction or servitude on the use, transfer, receipt
of income, or other exercise of any attributes of ownership, and (ii) any
Uniform Commercial Code financing statement or other public filing, notice or
record that by its terms purports to evidence or notify interested parties of
any of the matters referred to in clause (i) that has not been terminated or
released by another proper public filing, notice or record.

         2.7     Subsidiaries.  Schedule 2.7 sets forth a true, complete and
correct list of each subsidiary of Seller, including state or country of
organization and address of its principal executive offices.  Each subsidiary
of Seller is a corporation duly organized, validly existing and in good
standing under the laws of the jurisdiction of its organization, has all
requisite corporate power and authority to own, to lease or to operate its
properties and to carry on its business as it is now being conducted and is
duly qualified or licensed to do business in each jurisdiction in which the
character of its properties, owned or leased, or the nature of its activities
makes such qualification or license necessary, unless the failure to be so
licensed or qualified would not have a material, adverse effect on Seller.
Except as set forth in Schedule 2.7, all outstanding shares of capital stock
of each subsidiary of Seller were duly and validly issued and are fully paid,
nonassessable and owned by Seller or a subsidiary of Seller, free and clear of
all Encumbrances.  There are no options, warrants or other rights, agreements
or commitments (including preemptive rights) obligating Seller or any of its
subsidiaries to issue, to sell or to transfer any shares of capital stock or
other securities of any subsidiary of Seller.

         2.8     Liabilities.  Except as set forth in Schedule 2.8, Seller has
no liabilities or obligations, either accrued, absolute, contingent, or
otherwise that have a material adverse effect on the value or business of
Seller, and Seller has no knowledge of any potential liability that it
reasonably believes would likely result in a material adverse effect on the
value or business of the Seller, other than those (a) reflected or reserved
against in the unaudited consolidated balance sheet of Seller at November 30,
1996 or disclosed in other Seller SEC Documents or (b) incurred in the ordinary
course of business since November 30, 1996.

         2.9     Licenses, Permits, Authorizations, Etc.  Seller holds all
approvals, authorizations, consents, licenses, orders, franchises, rights,
registrations and permits of any type required to operate its business as
presently conducted.  The execution and delivery of this Agreement and the
consummation of the transactions contemplated hereby will not result in any
revocation, cancellation, suspension or modification of any such approval,
authorization, consent, license, order, franchise, right, registration or
permit.

         2.10    Title to Assets; Encumbrances.  Except as set forth in
Schedule 2.10:

                 2.10.1   Seller has good and indefeasible title to its assets,
whether real, personal or intangible, free and clear of all Encumbrances except
(i) as reflected in the Seller SEC Documents, (ii) liens for current taxes and
assessments not yet due or being contested in good faith by appropriate
proceedings, (iii) mechanic's liens arising under the operation of law for
actions contested in good faith or for which payment arrangements have been
made, (iv) liens granted or incurred by Seller in the ordinary course of its
business or financing of equipment, office space, furniture and computers in
the ordinary course of its business, and (v) easements, rights of way,
encroachments or other reductions or matters affecting title which do not
prevent the assets from being used for the purpose for which they are currently
being used;





                                       4
<PAGE>   5
                 2.10.2   There are no parties in possession of any of the
assets of Seller other than personal property held by third parties in the
reasonable and ordinary course of business.  Seller enjoys full, free and
exclusive use and quiet enjoyment of its assets and its rights pertaining
thereto.  Seller enjoys peaceful and undisturbed possession under all leases
under which it is a lessee, and all such leases are legal, valid and binding
obligations of Seller, enforceable against Seller in accordance with its terms.

         2.11    Taxes and Returns.  Seller has filed all required tax returns
and reports.  Seller has paid all taxes, assessments and governmental charges
and penalties which it has incurred, except such as are being or may be
contested in good faith by appropriate proceedings.  Seller is not delinquent
in the payment of any tax, assessment or governmental charge.  No deficiencies
for any taxes have been proposed, asserted, or assessed against Seller, and no
requests for waivers of the time to assess any such tax are pending.  For the
purposes of this Agreement, the term "tax" (including, with correlative
meaning, the terms "taxes" and "taxable") shall include all federal, state,
local and foreign income, profits, franchise, gross receipts, payroll, sales,
employment, use, property, withholding, excise and other taxes, duties or
assessments of any nature whatsoever, together with all interest, penalties and
additions imposed with respect to such amounts.

         2.12    Insurance.  Each policy of property, fire and casualty,
product liability, worker's compensation, professional liability and title
insurance and other forms of insurance (except group, health and life policies)
and each bond issued or posted by any person with respect to any operations or
other activities of Seller is, to the knowledge of Seller, the legal, valid and
binding obligation of the insurer or bond issuer, enforceable in accordance
with its terms, and is in an amount and provides for coverage as is customary
in the ordinary business practices of Seller's industry.

         2.13    Hazardous Wastes and Substances.  Except as set forth in
Seller SEC Documents, neither the operations of Seller nor the use of its
assets violates any applicable federal, state or local law, statute, ordinance,
rule, regulation, memorandum of understanding, order or notice requirement
pertaining to the collection, transportation, storage, treatment, discharge,
release or disposal of hazardous or non-hazardous waste or substances,
including without limitation (i) the Comprehensive Environmental Response,
Compensation and Liability Act of 1980 (42 U.S.C. Sections 9601 et seq.), as
amended from time to time on or before the Closing Date ("CERCLA") (including,
without limitation, as amended pursuant to the Superfund Amendments and
Reauthorization Act of 1986), and such regulations promulgated under CERCLA on
or before the Closing Date, (ii) the Resources Conservation and Recovery Act of
1976 (42 U.S.C. Sections 6901 et seq.), as amended from time to time ("RCRA")
on or before the Closing Date, and such regulations promulgated under RCRA,
(iii) any applicable federal, state or local laws or regulations relating to
the environment in effect on the Closing Date (collectively, the "Applicable
Environmental Laws").  Except as set forth in the Seller SEC Documents, none of
the operations of Seller has ever been conducted nor have any of its assets
been used in such a manner as to constitute a violation of any of the
Applicable Environmental Laws.  Except as set forth in Seller SEC Documents, no
notice has been served on Seller by any person or Governmental Entity regarding
any existing, pending or threatened investigation or inquiry related to
violations under any Applicable Environmental Law, or regarding any claims for
corrective action, remedial obligations or contribution for removal costs or
damages under any Applicable Environmental Law or regarding the designation of
Seller or any of its affiliates as a potentially responsible party for any
facility under the Applicable Environmental Laws, nor, does any fact or
circumstance exist which, if disclosed publicly, would be reasonably likely to
result in the service on Seller of any such notice.  Except as set forth on
Seller SEC Documents, there has been no action taken, or omitted to be taken by
Seller which has caused, or would be reasonably likely to cause, a "release" of
any "hazardous substance" at any "facility", without limitation, within the
meaning of such terms as





                                       5

defined in the Applicable Environmental Laws.

national market, have an average trading volume of at least 25,000 shares for
such 20 consecutive day period.  The trading volume limitation set forth in the
preceding sentence shall not be applicable on the Initial Maturity Date and the
Final Maturity Date, if applicable, provided that the Market Price of the
Common Stock for each of the 20 consecutive trading days prior to such dates is
$3.25 or more.  Notwithstanding the foregoing, in no event shall the Company be
entitled to require the Note to be converted, unless there is an effective
registration statement covering the shares of Common Stock to be issued upon
conversion.

                                   ARTICLE V

                         ADJUSTMENT OF CONVERSION PRICE

         5.1     Anti-Dilution Provisions.  The Conversion Price shall be
subject to adjustment from time to time as hereinafter provided.  Upon each
adjustment of the Conversion Price, the holder of this Note shall thereafter be
entitled to purchase, at the Conversion Price resulting from such adjustment,
the number of shares of Common Stock obtained by multiplying the Conversion
Price in effect immediately prior to such adjustment by the number of shares
purchasable pursuant hereto immediately prior to such adjustment and dividing
the product thereof by the Conversion Price resulting from such adjustment.

         5.2     Adjustment of Conversion Price Upon Issuance of Common Stock.

                 5.2.1    (A)   If and whenever after the date hereof the
Company shall issue or sell any Common Stock for no consideration or for a
consideration per share less than the Conversion Price then, forthwith, upon
such issue or sale, the Conversion Price shall be reduced (but not increased,
except as otherwise specifically provided in Section 5.2.2), to the price
(calculated to the nearest one-ten thousandth of a cent) determined by dividing
(x) an amount equal to the sum of (i) the aggregate number of shares of Common
Stock outstanding immediately prior to such issue or sale multiplied by the then
existing Conversion Price plus (ii) the consideration received by the Company
upon such issue or sale by (y) the aggregate number of shares of Common Stock
outstanding immediately after such issue or sale.

                          (B)   Notwithstanding the provisions of this Section
5.2, no adjustment shall be made in the Conversion Price in the event that the
Company issues, in one or more transactions, (i) Common Stock upon exercise of
any options issued to officers, directors or employees of the Company pursuant
to a stock option plan or an employment, severance or consulting agreement as
now or hereafter in effect, in each case approved by the Board of Directors
(provided that the aggregate number of shares of Common Stock which may be
issuable, including options issued prior to the date hereof, under all such
employee plans and agreements shall at no time exceed the number of such shares
of Common Stock outstanding on the date hereof on a fully diluted basis that are
issuable under currently effective employee plans and agreements); (ii) Common
Stock upon exercise of this Note or any other warrant issued pursuant to the
terms of the Purchase Agreement; (iii) Common Stock upon exercise of any stock
purchase warrant or option (other than the options referred to in clause (i)
above) or other convertible security outstanding on the date hereof; or (iv)
Common Stock issued as consideration in acquisitions.  In addition, for purposes
of calculating any adjustment of the Conversion Price as provided in this
Section 5.2, all of the shares of Common Stock issuable pursuant to any of the
foregoing shall be assumed to be outstanding prior to the event causing such
adjustment to be made.

                 5.2.2    For purposes of this Section 5.2, the following shall
         be applicable:

                 (A)      Issuance of Rights or Options.  In case at any time
         after the date hereof the Company shall in any manner grant (whether
         directly or by assumption in a merger or otherwise) any rights to
         subscribe for or to purchase, or any options for the purchase of,
         Common Stock or any stock or securities convertible into or
         exchangeable for Common Stock (such convertible or exchangeable stock
         or securities being herein called "Convertible Securities"), whether
         or not such rights or options or the right to convert or exchange any
         such Convertible Securities are immediately exercisable, and the price
         per share for which shares of Common Stock are issuable upon the
         exercise of such rights or options or upon conversion or exchange of
         such Convertible Securities (determined by dividing (i) the total
         amount, if any, received or receivable by the Company as consideration
         for the granting of such rights or options, plus the minimum aggregate
         amount of additional consideration, if any, payable to the Company
         upon the exercise of such rights or options, or plus, in the case of
         such rights or options that relate to Convertible Securities, the
         minimum aggregate amount of additional consideration, if any, payable
         upon the issue or sale of such Convertible Securities and upon the
         conversion or exchange thereof, by (ii) the total maximum number of
         shares of Common Stock issuable upon the exercise of such rights or
         options or upon the conversion or exchange of all such Convertible
         Securities issuable upon the exercise of such rights or options) shall
         be less than the Conversion Price in effect as of the date of granting
         such rights or options, then the total maximum number of shares of
         Common Stock issuable upon the exercise of such rights or options or
         upon conversion or exchange of all such Convertible Securities
         issuable upon the exercise of such rights or options shall be deemed
         to be outstanding as of the date of the granting of such rights or
         options and to have been issued for such price per share, with the
         effect on the Conversion Price specified in Section 5.2.1 hereof.
         Except as provided in Section 5.2.2 hereof, no further adjustment of
         the Conversion Price shall be made upon the actual issuance of such
         Common Stock or of such Convertible Securities upon exercise of such
         rights or options or upon the actual issuance of such Common Stock
         upon conversion or exchange of such Convertible Securities.

                 (B)      Change in Option Price or Conversion Rate.  Upon the
         happening of any of the following events, namely, if the purchase
         price provided for in any right or option referred to in Section
         5.2.2(A) above, the additional consideration, if any, payable upon the
         conversion or exchange of any Convertible Securities referred to in
         Section 5.2.2(A) hereof, or the rate at which any Convertible
         Securities referred to in Section 5.2.2(A) hereof, are convertible
         into or exchangeable for Common Stock shall change (other than under
         or by reason of provisions designed to protect against dilution), the
         Conversion Price then in effect hereunder shall forthwith be
         readjusted (increased or decreased, as the case may be) to the
         Conversion Price that would have been in effect at such time had such
         rights, options or Convertible Securities still outstanding provided
         for such changed purchase price, additional consideration or
         conversion rate, as the case may be, at the time initially granted,
         issued or sold.  On the expiration of any such option or right
         referred to in Section 5.2.2(A) hereof, or on the termination of any
         such right to convert or exchange any such Convertible Securities
         referred to in Section 5.2.2(A) hereof, the Conversion Price then in
         effect hereunder shall forthwith be readjusted (increased or
         decreased, as the case may be) to the Conversion Price that would have
         been in effect at the time of such expiration or termination had such
         right, option or Convertible Securities, to the extent outstanding
         immediately prior to such expiration or termination, never been
         granted, issued or sold, and the Common Stock issuable thereunder
         shall no longer be deemed to be outstanding.  If the purchase price
         provided for in Section 5.2.2(A) hereof or the rate at which any
         Convertible





                                     -8-
<PAGE>   9
         Securities referred to in Section 5.2.2(A) hereof are convertible into
         or exchangeable for Common Stock shall be reduced at any time under or
         by reason of provisions with respect thereto designed to protect
         against dilution, then in case of the delivery of Common Stock upon
         the exercise of any such right or option or upon conversion or
         exchange of any such Convertible Securities, the Conversion Price then
         in effect hereunder shall, if not already adjusted, forthwith be
         adjusted to such amount as would have obtained had such right, option
         or Convertible Securities never been issued as to such Common Stock
         and had adjustments been made upon the issuance of the Common Stock
         delivered as aforesaid, but only if as a result of such adjustment the
         Conversion Price then in effect hereunder is thereby reduced.


                 (C)      Consideration for Stock.  In case at any time Common
         Stock or Convertible Securities or any rights or options to purchase
         any such Common Stock or Convertible Securities shall be issued or
         sold for cash, the consideration therefor shall be deemed to be the
         amount received by the Company therefor.  In case at any time any
         Common Stock, Convertible Securities or any rights or options to
         purchase any such Common Stock or Convertible Securities shall be
         issued or sold for consideration other than cash, the amount of the
         consideration other than cash received by the Company shall be deemed
         to be the fair value of such consideration, as determined reasonably
         and in good faith by the Board of Directors of the Company.  In case
         at any time any Common Stock, Convertible Securities or any rights or
         options to purchase any Common Stock or Convertible Securities shall
         be issued in connection with any merger or consolidation in which the
         Company is the surviving corporation, the amount of consideration
         received therefor shall be deemed to be the fair value, as determined
         reasonably and in good faith by the Board of Directors of the Company,
         of such portion of the assets and business of the nonsurviving
         corporation as such Board of Directors may determine to be
         attributable to such Common Stock, Convertible Securities, rights or
         options as the case may be.  In case at any time any rights or options
         to purchase any shares of Common Stock or Convertible Securities shall
         be issued in connection with the issuance and sale of other securities
         of the Company, together consisting of one integral transaction in
         which no consideration is allocated to such rights or options by the
         parties, such rights or options shall be deemed to have been issued
         without consideration.

                 (D)      Record Date.  In case the Company shall take a record
         of the holders of its Common Stock for the purpose of entitling them
         (i) to receive a dividend or other distribution payable in Common
         Stock or Convertible Securities, or (ii) to subscribe for or purchase
         Common Stock or Convertible Securities, then such record date shall be
         deemed to be the date of the issuance or sale of the Common Stock or
         Convertible Securities deemed to have been issued or sold as a result
         of the declaration of such dividend or the making of such other
         distribution or the date of the granting of such right of subscription
         or purchase, as the case may be.

                 (E)      Treasury Shares.  The number of shares of Common
         Stock outstanding at any given time shall not include shares owned
         directly by the Company in treasury, and the disposition of any such
         shares shall be considered an issuance or sale of Common Stock for the
         purpose of this Section 5.2.

         5.3     Stock Dividends.  In case the Company shall declare a dividend
or make any other distribution upon any shares of the Company, payable in
Common Stock or Convertible Securities, any Common Stock or Convertible
Securities, as the case may be, issuable in payment of such dividend or
distribution shall be deemed to have been issued or sold without consideration.





                                         -9-
<PAGE>   10
         5.4     Stock Splits and Reverse Splits.  In the event that the
Company shall at any time subdivide its outstanding shares of Common Stock into
a greater number of shares, the Conversion Price in effect immediately prior to
such subdivision shall be proportionately reduced and the number of Shares into
which this Note may be converted immediately prior to such. subdivision shall
be proportionately increased, and conversely, in the event that the outstanding
shares of Common Stock shall at any time be combined into a smaller number of
shares, the Conversion Price in effect immediately prior to such combination
shall be proportionately increased and the number of Shares into which this
Note may be converted immediately prior to such combination shall be
proportionately reduced.  Except as provided in this Section 5.4 no adjustment
in the Conversion Price and no change in the number of Shares shall be made
under this Article v as a result of or by reason of any such subdivision or
combination.

         5.5     Reorganizations and Asset Sales.  If any capital
reorganization or reclassification of the capital stock of the Company, or any
consolidation, merger or share exchange of the Company with another Person,or
the sale, transfer or other disposition of all or substantially all of its
assets to another Person shall be effected in such a way that holders of Common
Stock shall be entitled to receive capital stock, securities or assets with
respect to or in exchange for their shares, then the following provisions shall
apply:

                 5.5.1    As a condition of such reorganization,
         reclassification, consolidation, merger, share exchange, sale,
         transfer or other disposition (except as otherwise provided below in
         Section 5.5.3), lawful and adequate provisions shall be made whereby
         the holder of this Note shall thereafter have the right to purchase
         and receive upon the terms; and conditions specified in this Note and
         in lieu of the shares immediately theretofore receivable upon the
         exercise of the rights represented hereby, such shares of capital
         stock, securities or assets as may be issued or payable with respect
         to or in exchange for a number of outstanding shares of such Common
         Stock equal to the number of shares immediately theretofore so
         receivable had such reorganization, reclassification, consolidation,
         merger, share exchange or sale not taken place, and in any such case
         appropriate provision reasonably satisfactory to such holder shall be
         made with respect to the rights and interests of such holder to the
         end that the provisions hereof (including, without limitation,
         provisions for adjustments of the Conversion Price and of the number
         of shares receivable upon the exercise) shall thereafter be
         applicable, as nearly as possible, in relation to any shares of
         capital stock, securities or assets thereafter deliverable upon the
         exercise of this Note.

                 5.5.2    In the event of a merger, share exchange or
         consolidation of the Company with or into another Person as a result
         of which a number of shares of common stock or its equivalent of the
         successor Person greater or lesser than the number of shares of Common
         Stock outstanding immediately prior to such merger, share exchange or
         consolidation are issuable to holders of Common Stock, then the
         Conversion Price in effect immediately prior to such merger, share
         exchange or consolidation shall be adjusted in the same manner as
         though there were a subdivision or combination of the outstanding
         shares of Common Stock.

                 5.5.3    The Company shall not effect any such consolidation,
         merger, share exchange, sale, transfer or other disposition unless
         prior to or simultaneously with the consummation thereof the
         successor Person (if other than the Company) resulting from such
         consolidation, share exchange or merger or the Person purchasing or
         otherwise acquiring such assets shall have assumed by written
         instrument executed and mailed or delivered to the Holder hereof at
         the last address of such Holder appearing on the books of the Company
         the obligation to deliver to such Holder such shares of capital stock,
         securities or assets as, in accordance with the foregoing provisions,
         such Holder may be entitled to receive, and all other liabilities and
         obligations of the Company hereunder.  Upon written request by





                                         -10-
<PAGE>   11
the Holder hereof, such Successor Person will issue a new Note revised to
reflect the modifications in this Note effected pursuant to this Section 5.5

          5.5.4    If a purchase, tender or exchange offer is made to and 
accepted by the holders of 50% or more of the outstanding shares of Common
Stock, the Company shall not effect any consolidation, merger, share exchange or
sale, transfer or other disposition of all or substantially all of the Company's
assets with the Person having made such offer or with any affiliate of such
Person, unless prior to the consummation of such consolidation, merger, share
exchange, sale, transfer or other disposition the holder hereof shall have been
given a reasonable opportunity to then elect to receive upon the conversion of
this Note either the capital stock, securities or assets then issuable with
respect to the Common Stock or the capital stock, securities or assets, or the
equivalent, issued to previous holders of the Common Stock in accordance with
such offer.

         5.6     Adjustment for Asset Distribution.  If the Company declares a
dividend or other distribution payable to all holders of shares of Common Stock
in evidences of indebtedness of the Company or other assets of the Company
(including, cash (other than regular cash dividends declared by the Board of
Directors), capital stock (other than Common Stock, Convertible Securities or
options or rights thereto) or other property), the Conversion Price in effect
immediately prior to such declaration of such dividend or other distribution
shall be reduced by an amount equal to the amount of such dividend or
distribution payable per share of Common Stock, in the case of a cash dividend
or distribution, or by the fair value of such dividend or distribution per
share of Common Stock (as reasonably determined in good faith by the Board of
Directors of the Company), in the case of any other dividend or distribution.
Such reduction shall be made whenever any such dividend or distribution is made
and shall be effective as of the date as of which a record is taken for purpose
of such dividend or distribution or, if a record is not taken, the date as of
which holders of record of Common Stock entitled to such dividend or
distribution are determined.

         5.7     De Minimis Adjustments.  No adjustment in the number of shares
of Common Stock purchasable hereunder shall be required unless such adjustment
would require an increase or decrease of at least one share of Common Stock
purchasable upon conversion of the Note and no adjustment in the Conversion
Price shall be required unless such adjustment would require an increase or
decrease of at least $.01 in the Conversion Price; provided, however, that any
adjustments which by reason of this Section 5.7 are not required to be made
shall be carried forward and taken into account in any subsequent adjustment.
All calculations shall be made to the nearest full share or nearest one
hundredth of a dollar, as applicable.

         5.8     Notice of Adjustment.  Whenever the Conversion Price or the
number of Shares issuable upon the conversion of the Note shall be adjusted as
herein provided, or the rights of the holder hereof shall change by reason of
other events specified herein, the Company shall compute the adjusted
Conversion Price and the adjusted number of Shares in accordance with the
provisions hereof and shall prepare an Officer's Certificate setting forth the
adjusted Conversion Price and the adjusted number of Shares issuable upon the
conversion of this Note or specifying the other shares of stock, securities or
assets receivable as a result of such change in rights, and showing in
reasonable detail the facts and calculations upon which such adjustments or
other changes are based.  The Company shall cause to be mailed to the Holder
hereof copies of such Officer's Certificate together with a notice stating that
the Conversion Price and the number of Shares purchasable upon conversion of
this Note have been adjusted and setting forth the adjusted Conversion Price
and the adjusted number of Shares purchasable upon conversion of this Note.

         5.9     Notifications to Holders.  In case at any time the Company
proposes:

                 (i)      to declare any dividend upon its Common Stock payable
         in capital stock or make any special dividend or other distribution
         (other than cash dividends) to the holders of its Common Stock;

                 (ii)     to offer for subscription pro rata to all of the
         holders of its Common Stock any additional shares of capital stock of
         any class or other rights;

                 (iii)    to effect any capital reorganization, or
         reclassification of the capital stock of the Company, or
         consolidation, merger or share exchange of the Company with another
         Person, or sale, transfer or other disposition of all or substantially
         all of its assets; or

                 (iv)    to effect a voluntary or involuntary dissolution,
         liquidation or winding up of the Company,

then, in any one or more of such cases, the Company shall give the holder
hereof (a) at least 10 days (but not more than 90 days) prior written notice of
the date on which the books of the Company shall close or a record shall be
taken for such dividend, distribution or subscription rights or for determining
rights to vote in respect of any such issuance, reorganization,
reclassification, consolidation, merger, share exchange, sale, transfer,
disposition, dissolution, liquidation or winding up, and (b) in the case of any
such issuance, reorganization, reclassification, consolidation, merger, share
exchange, sale, transfer, disposition, dissolution, liquidation or winding up,
at least 10 days (but not more than 90 days) prior written notice of the date
when the same shall take place.  Such notice in accordance with the foregoing
clause (a) shall also specify, in the case of any such dividend, distribution
or subscription rights, the date on which the holders of Common Stock shall be
entitled thereto, and such notice in accordance with the foregoing clause (b)
shall also specify the date on which the holders of Common Stock shall be
entitled to exchange their Common Stock, as the case may be, for securities or
other property deliverable upon such reorganization, reclassification,
consolidation, merger, share exchange, sale, transfer, disposition,
dissolution, liquidation or winding up, as the case may be.

         5.10    Company to Prevent Dilution.  If any event or condition occurs
as to which other provisions of this Article are not strictly applicable or if
strictly applicable would not fairly protect the exercise or purchase rights of
this Note evidenced hereby in accordance with the essential intent and
principles of such provisions, or that might materially and adversely affect
the exercise or purchase rights of the holder hereof under any provisions of
this Note, then the Company shall make such adjustments in the application of
such provisions, in accordance with such essential intent and principles, so as
to protect such exercise and purchase rights as aforesaid, and any adjustments
necessary with respect to the Conversion Price and the number of shares
purchasable hereunder so as to preserve the rights of the holder hereunder.  In
no event shall any such adjustment have the effect of increasing the Conversion
Price as otherwise determined pursuant to this Article except in the event of a
combination of shares of the type contemplated in Section 5.4 hereof, and then
in no event to an amount greater than the Conversion Price as adjusted pursuant
to Section 5.4 hereof.

                                   ARTICLE VI

                                   COVENANTS

         The Company covenants and agrees that, so long as this Note is
outstanding:

         6.1     Payment of Principal and Accrued Interest.  The Company will
duly and punctually pay or cause to be paid the principal sum of this Note,
together with interest accrued thereon from the date hereof to the date of
payment, in accordance with the terms hereof.

         6.2     Corporate Existence.  The Company will do or cause to be done
all things necessary to preserve and keep in full force and effect its corporate
existence, rights (charter and statutory) and franchises; provided, however,
that the Company shall not be required to preserve any such right or franchise
if it shall reasonably determine that the preservation thereof is no longer
desirable in the conduct of its business.

         6.3     Taxes; Claims; etc.  The Company will, and will cause each
Subsidiary to, promptly pay and discharge all lawful taxes, assessments, and
governmental charges or levies imposed upon it or upon its income or profits, or
upon any of its properties, real, personal, or mixed, before the same shall
become in default, as well as all lawful claims for labor, materials, and
supplies or otherwise which, if unpaid, might become a lien or charge upon such
properties or any part thereof, and which lien or charges will have a material
adverse effect on the business of the Company; provided, however, that neither
the Company nor any Subsidiary shall be required to pay or cause to be paid any
such tax, assessment, charge, levy, or claim prior to institution of
foreclosure proceedings if the validity thereof shall concurrently be contested
in good faith by appropriate proceedings and if the Company shall have
established reserves deemed by the Company adequate with respect to such tax,
assessment, charge, levy, or claim.

         6.4     Maintenance of Existence and Properties.  The Company will,
and will cause each Subsidiary to, keep its material properties in good repair,
working order, and condition, ordinary wear and tear excepted, so that the
business carried on may be properly conducted at all times in accordance with
prudent business management.

         6.5     SEC Reports.  The Company will deliver to the Holder within 20
days after it files them with the SEC, copies of its annual and quarterly
reports and of the information, documents, and other reports (or copies of such
portions of any of the foregoing as the SEC may by rules and regulations
prescribe) which the Company is required to file with the SEC pursuant to
Section 13 or 15(d) of the Securities Exchange Act of 1934.  The Company will

Indebtedness.

         7.8     Governing Law. This Note shall be governed by, and construed
in accordance with, the internal laws of the State of Delaware (without regard
to principles of choice of law).

         7.9     Usury. It is the intention of the parties hereto to conform
strictly to the applicable laws of the State of Delaware and the United States
of America, and judicial or administrative interpretations or determinations
thereof regarding the contracting for, charging and receiving of interest for
the use, forbearance, and detention of money (hereinafter referred to in this
Section 7.9 as "Applicable Law"). The Holder shall have no right to claim, to
charge or to receive any interest in excess of the maximum rate of interest, if
any, permitted to be charged on that portion of the amount representing
principal which is outstanding and unpaid from time to time by Applicable Law.
Determination of the rate of interest for the purpose of determining whether
this Note is usurious under Applicable Law shall be made by amortizing,
prorating, allocating and spreading in equal parts during the period of the
actual time of this Note, all interest or other sums deemed to be interest
(hereinafter referred to in this Section 7.9 as "Interest") at any time
contracted for, charged or received from the Company in connection with this
Note. Any Interest contracted for, charged or received in excess of the maximum
rate allowed by Applicable Law shall be deemed a result of a mathematical error
and a mistake. If this Note is paid in part prior to the end of the full stated
term of this Note and the Interest received for the actual period of existence
of this Note exceeds the maximum rate allowed by Applicable Law, Holder shall
credit the amount of the excess against any amount owing under this Note or, if
this Note has been paid in full, or in the event that it has been accelerated
prior to maturity, Holder shall refund to the Company the amount of such
excess, and shall not be subject to any of the penalties provided by Applicable
Law for contracting for, charging or receiving Interest in excess of the
maximum rate allowed by Applicable Law. Any such excess which is unpaid shall
be canceled.

         7.10    Subordination to NationsBank. Holder agrees that no payments
other than Permitted Payments (as hereinafter defined) shall be made by the
Company without the prior written consent of NationsBank to which the Company
may be indebted from time to time ("NationsBank Debt"). As used herein,
"Permitted Payments" shall mean (i) the payment of principal and interest
payment due on this Note on January 23, 1999 ("Maturity Payment"), (ii) any
repayment of principal and interest made with the proceeds of a public or
private offering of common or preferred stock of Company or (iii) any repayment
of principal and interest made with the proceeds of a placement of subordinated
debt with terms and conditions reasonably acceptable to NationsBank. Holder
agrees that the Maturity Payment shall not be received on this Note during the
continuance of an Event of Default (as defined in the NationsBank Loan
Agreement after any applicable cure periods) or if such Maturity Payment would
cause the occurrence of an Event of Default. Upon the occurrence and
continuance of a suspension of the Maturity Payment on this Note, the Maturity
Payment on this Note shall be automatically reinstated upon the expiration of
90 days following the date on which such Maturity Payment was suspended if,
within such 90-day period, NationsBank shall not have accelerated the
NationsBank Debt or exercised one or more of the Default Rights available to
NationsBank, even if such payment would cause the occurrence of an Event of
Default, provided that the Maturity Payment shall be automatically reinstated
if prior to the expiration of such ninety (90) day period NationsBank resumes
advances to Company.

                                   ARTICLE I

                              EXERCISE OF WARRANTS

         1.1     Method of Exercise. The Warrants represented hereby may be
exercised by the holder hereof, in whole or in part, at any time and from time
to time on or after the date hereof until 5:00 p.m., Houston, Texas time, on
January 24, 2002. To exercise the Warrants, the holder hereof shall deliver to
the Company, at the Warrant Office designated in Section 2.1 hereof, (i) a
written notice in the form of the Subscription Notice attached as an exhibit
hereto, stating therein the election of such holder to exercise the Warrants in
the manner provided in the Subscription Notice; (ii) payment in full of the
Exercise Price (A) in cash or by bank check for all Warrant Shares purchased
hereunder, or (B) through a "cashless" or "net-issue" exercise of each such
Warrant ("Cashless Exercise"); the holder shall exchange each Warrant subject
to a Cashless Exercise for that number of Warrant Shares determined by
multiplying the number of Warrant Shares issuable hereunder by a fraction, the
numerator of which shall be the difference between (x) the Market Price and (y)
the Exercise Price for each such Warrant, and the denominator of which shall be
the Market Price; the Subscription Notice shall set forth the calculation upon
which the Cashless Exercise is based, or (C) a combination of (A) and (B)
above; and (iii) this Warrant. The Warrants shall be deemed to be exercised on
the date of receipt by the Company of the Subscription Notice, accompanied by
payment for the Warrant Shares and surrender of this Warrant, as aforesaid, and
such date is referred to herein as the "Exercise Date". Upon such exercise, the
Company shall, as promptly as practicable and in any event within ten (10)
business days, issue and deliver to such holder a certificate or certificates
for the full number of the Warrant Shares purchased by such holder hereunder,
and shall, unless the Warrants have expired, deliver to the holder hereof a new
Warrant representing the number of Warrants, if any, that shall not have been
exercised, in all other respects





                                       2
<PAGE>   3
identical to this Warrant. As permitted by applicable law, the Person in whose
name the certificates for Common Stock are to be issued shall be deemed to have
become a holder of record of such Common Stock on the Exercise Date and shall
be entitled to all of the benefits of such holder on the Exercise Date,
including without limitation the right to receive dividends and other
distributions for which the record date falls on or after the Exercise Date and
to exercise voting rights.

         1.2     Expenses and Taxes. The Company shall pay all expenses, and
taxes (including, without limitation, all documentary, stamp, transfer or other
transactional taxes) other than income taxes attributable to the preparation,
issuance or delivery of the Warrants and of the shares of Common Stock issuable
upon exercise of the Warrants.

         1.3     Reservation of Shares. The Company shall reserve at all times
so long as the Warrants remain outstanding, free from preemptive rights, out of
its treasury Common Stock or its authorized but unissued shares of Common
Stock, or both, solely for the purpose of effecting the exercise of the
Warrants, a sufficient number of shares of Common Stock to provide for the
exercise of the Warrants.

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

         1.5     Purchase Agreement. The Warrants represented hereby are part
of a duly authorized issuance and sale of warrants to purchase Common Stock
issued and sold pursuant to that certain Agreement of Purchase and Sale
dated as of January 15, 1997 (the "Agreement"), between the Company and the
holder hereof. The holder hereof shall be entitled to registration under the
Securities Act and any applicable state securities or blue sky laws to the
extent set forth in the Registration Rights Agreement, as amended. The terms of
the Agreement are hereby incorporated herein for all purposes and shall be
considered a part of this Warrant as if they had been fully set forth herein.
Notwithstanding the previous sentence, in the event of any conflict between the
provisions of the Agreement and of this Warrant, the provisions of this Warrant
shall control.

         1.6     Acknowledgment of Rights. At the time of the exercise of the
Warrants in accordance with the terms hereof and upon the written request of
the holder hereof, the Company will acknowledge in writing its continuing
obligation to afford to such holder any rights (including, without limitation,
any right to registration of the Warrant Shares) to which such holder shall
continue to be entitled after such exercise in accordance with the provisions
of this Warrant; provided, however, that if the holder hereof shall fail to
make any such request, such failure shall not affect the continuing obligation
of the Company to afford to such holder any such rights.

         1.7     No Fractional Shares. The Company shall not be required to
issue fractional shares of Common Stock on the exercise of this Warrant. If
more than one Warrant shall be presented for exercise at the same time by the
same holder, the number of full shares of Common Stock which shall be issuable
upon such exercise shall be computed on the basis of the aggregate number of
whole shares of Common Stock purchasable on exercise of the Warrants so
presented. If any fraction of a share of Common Stock would, except for the
provisions of this Section 1.7, be issuable on the exercise of this Warrant,
the Company shall pay an amount in cash calculated by it to be equal to the
Market Price of one share of





                                       3
<PAGE>   4



Common Stock at the time of such exercise multiplied by such fraction computed
to the nearest whole cent.

                                   ARTICLE II

                                    TRANSFER

         2.1     Warrant Office. The Company shall maintain an office for
certain purposes specified herein (the "Warrant Office"), which office shall
initially be the Company's offices at 3200 Wilcrest Drive, Suite 440, Houston
Texas 77042, and may subsequently be such other office of the Company or of any
transfer agent of the Common Stock in the continental United States as to which
written notice has previously been given to the holder hereof. The Company
shall maintain, at the Warrant Office, a register for the Warrants in which the
Company shall record the name and address of the Person in whose name this
Warrant has been issued, as well as the name and address of each permitted
assignee of the rights of the registered owner hereof.

         2.2     Ownership of Warrants. The Company may deem and treat the
Person in whose name the Warrants are registered as the holder and owner hereof
(notwithstanding any notations of ownership or writing hereon made by anyone
other than the Company) for all purposes and shall not be affected by any
notice to the contrary until presentation of this Warrant for registration of
transfer as provided in this Article II. Notwithstanding the foregoing, the
Warrants represented hereby, if properly assigned in compliance with this
Article II, may be exercised by an assignee for the purchase of Warrant Shares
without having a new Warrant issued.

         2.3     Restrictions on Transfer of Warrants. The Company agrees to
maintain at the Warrant Office books for the registration and transfer of the
Warrants. Subject to the restrictions on transfer of the Warrants in this
Section 2.3, the Company, from time to time, shall register the transfer of the
Warrants in such books upon surrender of this Warrant at the Warrant Office
properly endorsed or accompanied by appropriate instruments of transfer and
written instructions for transfer satisfactory to the Company. Upon any such
transfer and upon payment by the holder or its transferee of any applicable
transfer taxes, new Warrants shall be issued to the transferee and the
transferor (as their respective interests may appear) and the surrendered
Warrants shall be cancelled by the Company. The Company shall pay all taxes
(other than securities transfer taxes or income taxes) and all other expenses
and charges payable in connection with the transfer of the Warrants pursuant to
this Section 2.3.

                 2.3.1     Restrictions in General. The holder of the Warrants
agrees that it will neither (i) transfer the Warrants prior to delivery to the
Company of written notice of such transfer, nor (ii) transfer such Warrant
Shares prior to delivery to the Company of written notice of such transfer, or
until registration of such Warrant Shares under the Securities Act and any
applicable state securities or blue sky laws has become effective.

         2.4     Compliance with Securities Laws. Subject to the terms of the
Registration Rights Agreement between the Holder and the Company dated as of
the date hereof and notwithstanding any other provisions contained in this
Warrant, the holder hereof understands and agrees that the following
restrictions and limitations shall be applicable to all Warrant Shares and to
all resales or other transfers thereof pursuant to the Securities Act:





                                       4
<PAGE>   5



                 2.4.1    The holder hereof agrees that the Warrant Shares
shall not be sold or otherwise transferred unless the Warrant Shares are
registered under the Securities Act and applicable state securities or blue sky
laws or are exempt therefrom.

                 2.4.2    A legend in substantially the following form will be
placed on the certificate(s) evidencing the Warrant Shares:

                 "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"),
OR ANY OTHER APPLICABLE SECURITIES LAW AND, ACCORDINGLY, THE SECURITIES
REPRESENTED BY THIS CERTIFICATE MAY NOT BE RESOLD, PLEDGED, OR OTHERWISE
TRANSFERRED, EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER, OR
IN A TRANSACTION EXEMPT FROM REGISTRATION UNDER, THE SECURITIES ACT AND IN
ACCORDANCE WITH ANY OTHER APPLICABLE SECURITIES LAWS."

                 2.4.3    Stop transfer instructions will be imposed with 
respect to the Warrant Shares so as to restrict resale or other transfer
thereof, subject to this Section 2.4.

                                  ARTICLE III

                                 ANTI-DILUTION

         3.1     Anti-Dilution Provisions. The Exercise Price shall be subject
to adjustment from time to time as hereinafter provided. Upon each adjustment
of the Exercise Price, the holder of this Warrant shall thereafter be entitled
to purchase, at the Exercise Price resulting from such adjustment, the number
of shares of Common Stock obtained by multiplying the Exercise Price in effect
immediately prior to such adjustment by the number of shares purchasable
pursuant hereto immediately prior to such adjustment and dividing the product
thereof by the Exercise Price resulting from such adjustment,

         3.2     Adjustment of Exercise Price Upon issuance of Common Stock.

                 3.2.1    (A) If and whenever after the date hereof the Company
shall issue or sell any Common Stock for no consideration or for a
consideration per share less than the Exercise Price, then, forthwith upon such
issue or sale, the Exercise Price shall be reduced (but not increased, except
as otherwise specifically provided in Section 3.2.2(C) hereof), to the price
(calculated to the nearest one-ten thousandth of a cent) determined by dividing
(x) an amount equal to the sum of (i) the aggregate number of shares of Common
Stock outstanding immediately prior to such issue or sale multiplied by then
existing Exercise Price plus (ii) the consideration received by the Company
upon such issue or sale by (y) the aggregate number of shares of Common Stock
outstanding immediately after such issue or sale.

                          (B)     Notwithstanding the provisions of this
Section 3.2, no adjustment shall be made in the Exercise Price in the event
that the Company issues, in one or more transactions, (i) Common Stock or
convertible securities upon exercise of any options issued to officers,
directors or employees of the Company pursuant to a stock option plan or an
employment, severance or consulting agreement as now or hereafter in effect, in
each case approved by the Board of Directors (provided that





                                       5
<PAGE>   6



the aggregate number of shares of Common Stock which may be issuable, including
options issued prior to the date hereof, under all such employee plans and
agreements shall at no time exceed the number of such shares of Common Stock
that are issuable under currently effective employee plans and agreements);
(ii) Common Stock upon exercise of the Warrants or any other warrant issued
pursuant to the terms of the Agreement or otherwise issued to the Holder; (iii)
Common Stock upon exercise of any stock purchase warrant or option (other than
the options referred to in clause (i) above) or other convertible security
outstanding on the date hereof; (iv) Common Stock upon conversion of the Note;
or (v) Common Stock issued as consideration in acquisitions. In addition, for
purposes of calculating any adjustment of the Exercise Price as provided in
this Section 3.2, all of the shares of Common Stock issuable pursuant to any of
the foregoing shall be assumed to be outstanding prior to the event causing
such adjustment to be made.

                 3.2.2    For purposes of this Section 3.2, the following
Sections 3.2.2(A) to 3.2.2(E) inclusive, shall be applicable:

                 (A)      Issuance of Rights or Options. In case at any time
         after the date hereof the Company shall in any manner grant (whether
         directly or by assumption in a merger or otherwise) any rights to
         subscribe for or to purchase, or any options for the purchase of,
         Common Stock or any stock or securities convertible into or
         exchangeable for Common Stock (such convertible or exchangeable stock
         or securities being herein called "Convertible Securities"), whether or
         not such rights or options or the right to convert or exchange any such
         Convertible Securities are immediately exercisable, and the price per
         share for which shares of Common Stock are issuable upon the exercise
         of such rights or options or upon conversion or exchange of such 
         Convertible Securities (determined by dividing (i) the total amount, if
         any, received or receivable by the Company as consideration for the
         granting of such rights or options, plus the minimum aggregate amount
         of additional consideration, if any, payable to the Company upon the
         exercise of such rights or options, or plus, in the case of such rights
         or options that relate to Convertible Securities, the minimum aggregate
         amount of additional consideration, if any, payable upon the issue or
         sale of such Convertible Securities and upon the conversion or exchange
         thereof, by (ii) the total maximum number of shares of Common Stock
         issuable upon the exercise of such rights or options or upon the
         conversion or exchange of all such Convertible Securities issuable upon
         the exercise of such rights or options) shall be less than the Exercise
         Price in effect as of the date of granting such rights or options, then
         the total maximum number of shares of Common Stock issuable upon the
         exercise of such rights or options or upon conversion or exchange of
         all such Convertible Securities issuable upon the exercise of such
         rights or options shall be deemed to be outstanding as of the date of
         the granting of such rights or options and to have been issued for such
         price per share, with the effect on the Exercise Price specified in
         Section 3.2.1 hereof. Except as provided in Section 3.2.2 hereof, no
         further adjustment of the Exercise Price shall be made upon the actual
         issuance of such Common Stock or of such Convertible Securities upon
         exercise of such rights or options or upon the actual issuance of such
         Common Stock upon conversion or exchange of such Convertible
         Securities.

                 (B)      Change in Option Price or Conversion Rate. Upon the
         happening of any of the following events, namely, if the purchase
         price provided for in any right or option referred to in Section
         3.2.2, the additional consideration, if any, payable upon the
         conversion or exchange of any Convertible Securities referred to in
         Section 3.2.2, or the rate at which any Convertible Securities
         referred to in Section 3.2.2, are convertible into or exchangeable for
         Common Stock shall change (other than under or by reason of provisions
         designed to protect against dilution),





                                       6
<PAGE>   7
         the Exercise Price then in effect hereunder shall forthwith be
         readjusted (increased or decreased, as the case may be) to the
         Exercise Price that would have been in effect at such time had such
         rights, options or Convertible Securities still outstanding provided
         for such changed purchase price, additional consideration or
         conversion rate, as the case may be, at the time initially granted,
         issued or sold. On the expiration of any such option or right referred
         to in Section 3.2.2, or on the termination of any such right to
         convert or exchange any such Convertible Securities referred to in
         Section 3.2.2, the Exercise Price then in effect hereunder shall
         forthwith be readjusted (increased or decreased, as the case may be)
         to the Exercise Price that would have been in effect at the time of
         such expiration or termination had such right, option or Convertible
         Securities, to the extent outstanding immediately prior to such
         expiration or termination, never been granted, issued or sold, and the
         Common Stock issuable thereunder shall no longer be deemed to be
         outstanding. If the purchase price provided for in Section 3.2.2 or
         the rate at which any Convertible Securities referred to in Section
         3.2.2 reduced at any time under or by reason of provisions with
         respect thereto designed to protect against dilution, then in case of
         the delivery of Common Stock upon the exercise of any such right or
         option or upon conversion or exchange of any such Convertible
         Securities, the Exercise Price then in effect hereunder shall, if not
         already adjusted, forthwith be adjusted to such amount as would have
         obtained had such right, option or Convertible Securities never been
         issued as to such Common Stock and had adjustments been made upon the
         issuance of the Common Stock delivered as aforesaid, but only if as a
         result of such adjustment the Exercise Price then in effect hereunder
         is thereby reduced.

                 (C)      Consideration for Stock. In case at any time Common
         Stock or Convertible Securities or any rights or options to purchase
         any such Common Stock or Convertible Securities shall be issued or
         sold for cash, the consideration therefor shall be deemed to be the
         amount received by the Company therefor. In case at any time any
         Common Stock, Convertible Securities or any rights or options to
         purchase any such Common Stock or Convertible Securities shall be
         issued or sold for consideration other than cash, the amount of the
         consideration other than cash received by the Company shall be deemed
         to be the fair value of such consideration, as determined reasonably
         and in good faith by the Board of Directors of the Company. In case at
         any time any Common Stock, Convertible Securities or any rights or
         options to purchase any Common Stock or Convertible Securities shall
         be issued in connection with any merger or consolidation in which the
         Company is the surviving corporation, the amount of consideration
         received therefor shall be deemed to be the fair value, as determined
         reasonably and in good faith by the Board of Directors of the Company,
         of such portion of the assets and business of the nonsurviving
         corporation as such Board of Directors may determine to be
         attributable to such Common Stock, Convertible Securities, rights or
         options as the case may be. In case at any time any rights or options
         to purchase any shares of Common Stock or Convertible Securities shall
         be issued in connection with the issuance and sale of other securities
         of the Company, together consisting of one integral transaction in
         which no consideration is allocated to such rights or options by the
         parties, such rights or options shall be deemed to have been issued
         with consideration.

                 (D)      Record Date. In the case the Company shall take a
         record of the holders of its Common Stock for the purpose of entitling
         them (i) to receive a dividend or other distribution payable in Common
         Stock or Convertible Securities, or (ii) to subscribe for or purchase
         Common Stock or Convertible Securities, then such record date shall be
         deemed to be the date of the issuance or sale of the Common Stock or
         Convertible Securities deemed to have been issued or





                                       7
<PAGE>   8
         sold as a result of the declaration of such dividend or the making of
         such other distribution or the date of the granting of such right of
         subscription or purchase, as the case may be.

                 (E)     Treasury Shares. The number of shares of Common Stock
         outstanding at any given time shall not include shares owned directly
         by the Company in treasury, and the disposition of any such shares
         shall be considered an issuance or sale of Common Stock for the
         purpose of this Section 3.2.
                         
         3.3     Stock Dividends. In case the Company shall declare a dividend
or make any other distribution upon any shares of the Company, payable in
Common Stock or Convertible Securities, any Common Stock or Convertible
Securities, as the case may be, issuable in payment of such dividend or
distribution shall be deemed to have been issued or sold without consideration.

         3.4     Stock Splits and Reverse Splits. In the event that the Company
shall at any time subdivide its outstanding shares of Common Stock into a
greater number of shares, the Exercise Price in effect immediately prior to
such subdivision shall be proportionately reduced and the number of Warrant
Shares purchasable pursuant to this Warrant immediately prior to such
subdivision shall be proportionately increased, and conversely, in the event
that the outstanding shares of Common stock shall at any time be combined into
a smaller number of shares, the Exercise Price in effect immediately prior to
such combination shall be proportionately increased and the number of Warrant
Shares purchasable upon the exercise of this Warrant immediately prior to such
combination shall be proportionately reduced.  Except as provided in this
Section 3.4, no adjustment in the Exercise Price and no change in the number of
Warrant Shares purchasable shall be made under this Article III as a result of
or by reason of any such subdivision or combination.

         3.5     Reorganizations and Asset Sales. If any capital reorganization
or reclassification of the capital stock of the Company, or any consolidation,
merger or share exchange of the Company with another Person, or the sale,
transfer or other disposition of all or substantially all of its assets to
another Person shall be effected in such a way that a holder of Common Stock of
the Company shall be entitled to receive capital stock, securities or assets
with respect to or in exchange for their shares, then the following provisions
shall apply:

                 3.5.1   As a condition of such reorganization,
reclassification, consolidation, merger, share exchange, sale, transfer or
other disposition (except as otherwise provided below in this Section 3.5),
lawful and adequate provisions shall be made whereby the holder of Warrants
shall thereafter have the right to purchase and receive upon the terms and
conditions specified in this Warrant and in lieu of the Warrant Shares
immediately theretofore receivable upon the exercise of the rights represented
hereby, such shares of capital stock, securities or assets as may be issued or
payable with respect to or in exchange for a number of outstanding shares of
such Common Stock equal to the number of Warrant Shares immediately theretofore
so receivable had such reorganization, reclassification, consolidation, merger,
share exchange or sale not taken place, and in any such case appropriate
provision reasonably satisfactory to such holder shall be made with respect to
the rights and interests of such holder to the end that the provisions hereof
(including, without limitation, provisions for adjustments of the Exercise
Price and of the number of Warrant Shares receivable upon the exercise) shall
thereafter be applicable, as nearly as possible, in relation to any shares of
capital stock, securities or assets thereafter deliverable upon the exercise of
Warrants.





                                       8
<PAGE>   9
                 3.5.2   In the event of a merger, share exchange or
consolidation of the Company with or into another Person as a result of which a
number of shares of common stock or its equivalent of the successor Person
greater or lesser than the number of shares of Common Stock outstanding
immediately prior to such merger, share exchange or consolidation are issuable
to holders of Common Stock, then the Exercise Price in effect immediately prior
to such merger, share exchange or consolidation shall be adjusted in the same
manner as though there were a subdivision or combination of the outstanding
shares of Common Stock.                      

                 3.5.3   The Company shall not effect any such consolidation,
merger, share exchange, sale, transfer or other disposition unless prior to or
simultaneously with the consummation thereof the successor Person (if other
than the Company) resulting from such consolidation, share exchange or merger
or the Person purchasing or otherwise acquiring such assets shall have assumed
by written instrument executed and mailed or delivered to the holder hereof at
the last address of such holder appearing on the books of the Company the
obligation to deliver to such holder such shares of capital stock, securities
or assets as, in accordance with the foregoing provisions, such holder may be
entitled to receive, and all other liabilities and obligations of the Company
hereunder. Upon written request by the holder hereof, such successor Person
will issue a new Warrant revised to reflect the modifications in this Warrant
effected pursuant to this Section 3.5.
                             
                 3.5.4   If a purchase, tender or exchange offer is made to and
accepted by the holders of 50% or more of the outstanding shares of Common
Stock, the Company shall not effect any consolidation, merger, share exchange
or sale, transfer or other disposition of all or substantially all of the
Company's assets with the Person having made such offer or with any affiliate
of such Person, unless prior to the consummation of such consolidation,
merger, share exchange, sale, transfer or other disposition the holder hereof
shall have been given a reasonable opportunity to then elect to receive upon
the exercise of the Warrants either the capital stock, securities or assets
then issuable with respect to the Common Stock or the capital stock, securities
or assets, or the equivalent, issued to previous holders of the Common Stock in
accordance with such offer.

         3.6     Adjustment for Asset-Distribution. If the Company declares a
dividend or other distribution payable to all holders of shares of Common Stock
in evidences of indebtedness of the Company or other assets of the Company
(including, cash (other than regular cash dividends declared by the Board of
Directors), capital stock (other than Common Stock, Convertible Securities or
options or rights thereto) or other property), the Exercise Price in effect
immediately prior to such declaration of such dividend or other distribution
shall be reduced by an amount equal to the amount of such dividend or
distribution payable per share of Common Stock, in the case of a cash dividend
or distribution, or by the fair value of such dividend or distribution per
share of Common Stock (as reasonably determined in good faith by the Board of
Directors of the Company), in the case of any other dividend or distribution.
Such reduction shall be made whenever any such dividend or distribution is made
and shall be effective as of the date as of which a record is taken for purpose
of such dividend or distribution or, if a record is not taken, the date as of
which holders of record of Common Stock entitled to such dividend or
distribution are determined.

         3.7     De Minimis Adjustments. No adjustment in the number of shares
of Common Stock purchasable hereunder shall be required unless such adjustment
would require an increase or decrease of at least one share of Common Stock
purchasable upon an exercise of each Warrant and no adjustment in the Exercise
Price shall be required unless such adjustment would require an increase or
decrease of at least $0.01 in the Exercise Price; provided, however, that any
adjustments which by reason of this





                                       9
<PAGE>   10
Section 3.7 are not required to be made shall be carried forward and taken into
account in any subsequent adjustment.  All calculations shall be made to the
nearest full share or nearest one hundredth of a dollar, as applicable.

         3.8     Notice of Adjustment. Whenever the Exercise Price or the
number of Warrant Shares issuable upon the exercise of the Warrants shall be
adjusted as herein provided, or the rights of the holder hereof shall change by
reason of other events specified herein, the Company shall compute the adjusted
Exercise Price and the adjusted number of Warrant Shares in accordance with the
provisions hereof and shall prepare an Officer's Certificate setting forth the
adjusted Exercise Price and the adjusted number of Warrant Shares issuable upon
the exercise of the Warrants or specifying the other shares of stock,
securities or assets receivable as a result of such change in rights, and
showing in reasonable detail the facts and calculations upon which such
adjustments or other changes are based. The Company shall cause to be mailed to
the holder hereof copies of such Officer's Certificate together with a notice
stating that the Exercise Price and the number of Warrant Shares purchasable
upon exercise of the Warrants have been adjusted and setting forth the adjusted
Exercise Price and the adjusted number of Warrant Shares purchasable upon the
exercise of the Warrants.

         3.9     Notifications to Holders. In case at any time the Company
proposes:

                 (i)      to declare any dividend upon its Common Stock payable
         in capital stock or make any special dividend or other distribution
         (other than cash dividends) to the holders of its Common Stock;

                 (ii)     to offer for subscription pro rata to all of the
         holders of its Common Stock any additional shares of capital stock of
         any class or other rights;

                 (iii)    to effect any capital reorganization, or
         reclassification of the capital stock of the Company, or
         consolidation, merger or share exchange of the Company with another
         Person, or sale, transfer or other disposition of all or substantially
         all of its assets; or

                 (iv)     to effect a voluntary or involuntary dissolution,
         liquidation or winding up of the Company,

then, in any one or more of such cases, the Company shall give the holder
hereof (a) at least 10 days' (but not more than 90 days') prior written notice
of the date of which the books of the Company shall close or a record shall be
taken for such dividend, distribution or subscription rights or for determining
rights to vote in respect of such issuance, reorganization, reclassification,
consolidation, merger, share exchange, sale, transfer, disposition,
dissolution, liquidation or winding up, and (b) in the case of any such
issuance, reorganization, reclassification, consolidation, merger, share
exchange, sale, transfer, disposition, dissolution, liquidation or winding up,
at least 10 days' (but not more than 90 days') prior written notice of the date
when the same shall take place. Such notice in accordance with the foregoing
clause (a) shall also specify, in the case of any such dividend, distribution
or subscription rights, the date on which the holders of Common Stock shall be
entitled thereto, and such notice in accordance with the foregoing clause (b)
shall also specify the date on which the holders of Common Stock shall be
entitled to exchange their Common Stock, as the case may be, for securities or
other property deliverable upon such reorganization, reclassification,
consolidation, merger, share exchange, sale, transfer, disposition,
dissolution, liquidation or winding up, as the case may be.

         3.10    Company to Prevent Dilution. If any event or condition occurs
as to which other provisions of this Article III are not strictly applicable or
if strictly applicable would not fairly protect the exercise or purchase rights
of the Warrants evidenced hereby in accordance with the essential intent and
principles of such provisions, or that might materially and adversely affect
the exercise or purchase rights of the holder hereof under any provisions of
this Warrant, then the Company shall make such adjustments in the application
of such provisions, in accordance with such essential intent and principles, so
as to protect such exercise and purchase rights as aforesaid, and any 
adjustments necessary with respect to the Exercise Price and the number of
Warrant Shares purchasable hereunder so as to preserve the rights of the holder
hereunder. In no event shall any such adjustment have the effect of increasing
the Exercise Price as otherwise determined pursuant to this Article III except
in the event of a combination of shares of the type contemplated in Section 3.4
hereof, and then in no event to an amount greater than the Exercise Price as
adjusted pursuant to Section 3.4 hereof.

                                   ARTICLE IV

                                 MISCELLANEOUS

thereof and any term or provision of this Warrant may be amended or
supplemented at any time by agreement of the holder hereof and the Company,
except that any waiver of any term or condition, or any amendment or
supplementation, of this Warrant shall be in writing. A waiver of any breach or
failure to enforce any of the terms or conditions of this Warrant shall not in
any way effect, limit or waive a party's rights hereunder at any time to
enforce strict compliance thereafter with every term or condition of this
Warrant.

         4.4     Illegality. In the event that any one or more of the
provisions contained in this Warrant shall be determined to be invalid, illegal

enforceability of any such provision in any other respect and the remaining
provisions of this Warrant shall not, at the election of the party for whom the
benefit of the provision exists, be in any way impaired.

         4.5     Copy of Warrant. A copy of this Warrant shall be filed among
the records of the Company.

         4.7     Limitation of Liability; Not Stockholders. No provision of
this Warrant shall be construed as conferring upon the holder hereof the right
to vote, consent, receive dividends or receive notices (other than as herein
expressly provided) in respect of meetings of stockholders for the election of
directors of the Company or any other matter whatsoever as a stockholder of the
Company. No provision hereof, in the absence of affirmative action by the

with any exchange or replacement. The Company shall pay all taxes (other than
securities transfer taxes or income taxes) and all other expenses and charges
payable in connection with the preparation, execution and delivery of Warrants

                         REGISTRATION RIGHTS AGREEMENT

         THIS REGISTRATION RIGHTS AGREEMENT (this "Registration Rights

thereunder, all as the same shall be in effect at the time.

         "Selling Expenses" shall mean all underwriting discounts, selling

         "Underwritten Public Offering" shall mean a public offering in which

                                   ARTICLE II

                              REGISTRATION RIGHTS

         2.1      Demand Registration.

                 2.1.1 At anytime and from time to time, a holder or holders of
Registrable Securities holding in the aggregate at least 50% of the then
existing Registrable Securities may make a one-time written demand upon the
Company, to file, within 60 days after such written demand is made, with the
Securities and Exchange Commission a shelf registration statement covering the
resale of the Registrable Securities on Form S-1, S-2 or S-3 (the "Registration
Statement"). The Company shall use its reasonable best efforts to cause such
Registration Statement to become effective as soon as practicable and to cause
the Registrable Securities to be qualified in such state jurisdictions as the
holders may request.

                 2.1.2    Except as set forth herein, the Company shall take
all reasonable steps necessary to keep the Registration Statement current and
effective until the lesser of: (i) three years and (ii) until the Registrable
Securities are transferable pursuant to Rule 144 under the Securities Act
without the volume limitations set forth in such rule.

                 2.1.3    The Company shall be entitled to require that a
holder or holders of Registrable Securities refrain from effecting any public
sales or distributions of the Registrable Securities pursuant to a Registration
Statement that has been declared effective by the Commission or otherwise, if
the board of directors of the Company reasonably determines that such public
sales or distributions would interfere in any material respect with any
transaction involving the Company that the board of directors reasonably
determines to be material to the Company. The board of directors shall, as
promptly as practicable, give the holders of the Registrable Securities written
notice of any such development. In the event of a request by the board of
directors of the Company that the holders of Registrable Securities refrain
from effecting any public sales or distributions of the Registrable Securities,
the Company shall be required to lift such restrictions regarding effecting
public sales or distributions of the Registrable Securities as soon as
reasonably practicable after the board of directors shall reasonably determine
public sales or distributions by the holders of the Registrable Securities
shall not interfere with such transaction, provided, that in no event shall any
requirement that the holders of Registrable Securities refrain from effecting
public sales or distributions in the Registrable Securities extend for more
than 90 days.

         2.2      Piggyback Registration.

<PAGE>   3
                 2.2.1   Subject to the terms hereof, if at any time or from
time to time the Company or any shareholder of the Company shall determine to
register any of its securities (except for registration statements relating to
employee benefit plans or exchange offers), either for its own account or the
account of a security holder, the Company will promptly give to the holders of
Registrable Securities written notice thereof no less the 30 days prior to the
filing of any registration statement; and include in such registration (and any
related qualification under blue sky laws or other compliance), and in the
underwriting involved therein, if any, such Registrable Securities as such
holders may request in a writing delivered to the Company within 20 days after
the holders' receipt of Company's written notice.

                 2.2.2   The holders of Registrable Securities may participate
in any number of registrations until all of the Shares held by holders of
Registrable Securities have been distributed pursuant to a registration or
until the Shares are transferable pursuant to Rule 144 under the Securities
Act.

                 2.2.3   If any registration statement is an Underwritten Public
Offering, the right of holders of Registrable Securities to registration
pursuant to this Section shall be conditioned upon each such holder's
participation in such reasonable underwriting arrangements as the Company shall
make regarding the offering, and the inclusion of Registrable Securities in the
underwriting shall be limited to the extent provided herein. Holders of
Registrable Securities and all other shareholders proposing to distribute their
securities through such underwriting shall (together with the Company and the
other holders distributing their securities through such underwriting) enter
into an underwriting agreement in customary form with the managing underwriter
selected for such underwriting by the Company. Notwithstanding any other
provision of this Section, if the managing underwriter concludes in its
reasonable judgment that the number of shares to be registered for selling
shareholders (including the holders of Registrable Securities) would materially
adversely effect such offering, the number of Shares to be registered, together
with the number of shares of Common Stock or other securities held by other
shareholders proposed to be registered in such offering, shall be reduced on a
pro rata basis based on the number of Shares proposed to be sold by the holders
of Registrable Securities as compared to the number of shares proposed to be
sold by all shareholders. If any holder of Registrable Securities disapproves of
the terms of any such underwriting, it may elect to withdraw therefrom by
written notice to the Company and the managing underwriter, delivered not less
than 10 days before the effective date.  The Registrable Securities excluded by
the managing underwriter or withdrawn from such underwriting shall be withdrawn
from such registration, and shall not be transferred in a public distribution
prior to 120 days after the effective date of the registration statement
relating thereto, or such other shorter period of time as the underwriters may
require.

                 2.2.4   The Company shall have the right to terminate or
withdraw any registration initiated by it under this Section prior to the
effectiveness of such registration whether or not the holders of Registrable
Securities have elected to include securities in such registration.

        2.3     Expenses of Registration. All Registration Expenses shall be
borne by the Company. Unless otherwise stated herein, all Selling Expenses
relating to securities registered on behalf of the holders of Registrable
Securities shall be borne by the holders of Registrable Securities.

        2.4     Best Registration Rights. If, on or after the date of this 
Registration Rights Agreement, the Company grants to any person with respect to
any security issued by the Company or any of its Subsidiaries registration
rights that provide for terms that are in any manner more favorable to the
holder of such registration rights than the terms granted to the Purchaser (or
if the Company amends or waives any provision of any Agreement providing
registration rights of others or takes any other action


                                     -3-

<PAGE>   4
whatsoever to provide for terms that are more favorable to other holders than
the terms provided to the Purchaser) then this Registration Rights Agreement
shall immediately be deemed amended to provide the holders of Registrable
Securities with any (or all) of such more favorable terms as the holders of
Registrable Securities shall elect to include herein.

         2.5     Registration Procedures. In the case of each registration,
qualification or compliance effected by the Company pursuant to this
Registration Rights Agreement, the Company will keep the holders of Registrable
Securities advised in writing as to the initiation of each registration,
qualification and compliance and as to the completion thereof. At its expense,
the Company will:

                 2.5.1    Prepare and file with the Commission a registration
statement with respect to such securities and use its commercially reasonable
efforts to cause such registration statement to become and remain effective
until the distribution described in such registration statement has been
completed;

                 2.5.2    Furnish to each underwriter such number of copies of
a prospectus, including a preliminary prospectus, in conformity with the
requirements of the Securities Act, and such other documents as such
underwriter may reasonably request in order to facilitate the public sale of
the shares by such underwriter, and promptly furnish to each underwriter and
the holders of Registrable Securities notice of any stop-order or similar
notice issued by the Commission or any state agency charged with the regulation
of securities, and notice of any Nasdaq or securities exchange listing; and

                 2.5.3    Cause the Shares to be listed on the Nasdaq small-cap
market or a securities exchange on which the Common Stock is approved for
listing.

         2.6     Indemnification.

                 2.6.1    To the extent permitted by law, the Company will
indemnify each holder of Registrable Securities, each of its officers and
directors and partners, and each person controlling such holder within the
meaning of Section 15 of the Securities Act, with respect to which
registration, qualification or compliance has been effected pursuant to this
Agreement, and each underwriter, if any, and each person who controls any
underwriter within the meaning of Section 15 of the Securities Act, against all
expenses, claims, losses, damages or liabilities (or actions in respect
thereof), including any of the foregoing incurred in settlement of any
litigation, commenced or threatened, to the extent such expenses, claims,
losses, damages or liabilities arise out of or are based on any untrue
statement (or alleged untrue statement) of a material fact contained in any
registration statement, prospectus, offering circular or other similar
document, or any amendment or supplement thereto, incident to any such
registration, qualification or compliance, or based on any omission (or alleged
omission) to state therein a material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances in
which they were made, not misleading, or any violation by the Company of the
Securities Act or any rule or regulation promulgated under the Securities Act
applicable to the Company in connection with any such registration,
qualification or compliance, and the Company will reimburse each holder of
Registrable Securities, each of its officers and directors and partners, and
each person controlling each holder of Registrable Securities, each such
underwriter and each person who controls any such underwriter, for any legal
and any other expenses reasonably incurred in connection with investigating,
preparing or defending any such claim, loss, damage, liability or action;
provided, however, that the indemnity contained herein shall not apply to
amounts paid in settlement of any claim, loss, damage, liability or expense if
settlement is effected without the consent of the Company (which consent shall
not unreasonably be withheld); provided, further, that the Company will not be
liable in any


                                     -4-
<PAGE>   5
such case to the extent that any such claim, loss, damage, liability or expense
arises out of or is based on any untrue statement or omission or alleged untrue
statement or omission, made in reliance upon and in conformity with written
information furnished to the Company by a holder of Registrable Securities,
such controlling person or such underwriter specifically for use therein.
Notwithstanding the foregoing, insofar as the foregoing indemnity relates to
any such untrue statement (or alleged untrue statement) or omission (or alleged
omission) made in the preliminary prospectus but eliminated or remedied in the
amended prospectus on file with the Commission at the time the registration
statement becomes effective or in the final prospectus filed with the
Commission pursuant to the applicable rules of the Commission or in any
supplement or addendum thereto, the indemnity agreement herein shall not inure
to the benefit of any underwriter if a copy of the final prospectus filed
pursuant to such rules, together with all supplements and addenda thereto, was
not furnished to the person or entity asserting the loss, liability, claim or
damage at or prior to the time such furnishing is required by the Securities
Act.

                 2.6.2    To the extent permitted by law, each holder of
Registrable Securities will, if securities held by such holder are included in
the securities as to which such registration, qualification or compliance is
being effected pursuant to terms hereof, indemnify the Company, each of its
directors and officers, each underwriter, if any, of the Company's securities
covered by such a registration statement, each person who controls the Company
or such underwriter within the meaning of Section 15 of the Securities Act, and
each other person selling the Company's securities covered by such registration
statement, each of such person's officers and directors and each person
controlling such persons within the meaning of Section 15 of the Securities
Act, against all claims, losses, damages and liabilities (or actions in respect
thereof) arising out of or based on any untrue statement (or alleged untrue
statement) of a material fact contained in any such registration statement,
prospectus, offering circular or other document, or any omission (or alleged
omission) to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, or any violation by a
holder of Registrable Securities of any rule or regulation promulgated under
the Securities Act applicable to holders of Registrable Securities and relating
to action or inaction required of holders of Registrable Securities in
connection with any such registration, qualification or compliance, and will
reimburse the Company, such other persons, such directors, officers, persons,
underwriters or control persons for any legal or other expenses reasonably
incurred in connection with investigating or defending any such claim, loss,
damage, liability or action, in each case to the extent, but only to the
extent, that such untrue statement (or alleged untrue statement) or omission
(or alleged omission) is made in such registration statement, prospectus,
offering circular or other document in reliance upon and in conformity with
written information furnished to the Company by such holder of Registrable
Securities specifically for use therein; provided, however, that the indemnity
contained herein shall not apply to amounts paid in settlement of any claim,
loss, damage, liability or expense if settlement is effected without the
consent of such holder of Registrable Securities (which consent shall not be
unreasonably withheld). Notwithstanding the foregoing, the liability of such
holder of Registrable Securities under this subsection (b) shall be limited in
an amount equal to the net proceeds from the sale of the shares sold by such
holder of Registrable Securities, unless such liability arises out of or is
based on willful conduct by such holder of Registrable Securities. In addition,
insofar as the foregoing indemnity relates to any such untrue statement (or
alleged untrue statement) or omission (or alleged omission) made in the
preliminary prospectus but eliminated or remedied in the amended prospectus on
file with the Commission at the time the registration statement becomes
effective or in the final prospectus filed pursuant to applicable rules of the
Commission or in any supplement or addendum thereto, the indemnity agreement
herein shall not inure to the benefit of the Company or any underwriter, if a
copy of the final prospectus filed pursuant to such rules, together with all
supplements and addenda thereto, was not furnished to the person or entity


                                     -5-
<PAGE>   6

asserting the loss, liability, claim or damage at or prior to the time such
furnishing is required by the Securities Act.

                 2.6.3    Notwithstanding the foregoing paragraphs (a) and (b)
of this Section, each party entitled to indemnification under this Section (the
"Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and
shall permit the Indemnifying Party to assume the defense of any such claim or
any litigation resulting therefrom, provided that counsel for the Indemnifying
Party, who shall conduct the defense of such claim or litigation, shall be
approved by the Indemnified Party (whose approval shall not unreasonably be
withheld), and the Indemnified Party may participate in such defense at such
party's expense, and provided further that the failure of any Indemnified Party
to give notice as provided herein shall not relieve the Indemnifying Party of
its obligations under this Agreement unless the failure to give such notice is
materially prejudicial to an Indemnifying Party's ability to defend such action
and provided further, that the Indemnifying Party shall not assume the defense
for matters as to which there is a conflict of interest or as to which the
Indemnifying Party is asserting separate or different defenses, which defenses
are inconsistent with the defenses of the Indemnified Party. No Indemnifying
Party, in the defense of any such claim or litigation, shall, except with the
consent of each Indemnified Party, consent to entry of any judgment or enter
into any settlement which does not include as an unconditional term thereof the
giving by the claimant or plaintiff to such Indemnified Party of a release from
all liability in respect to such claim or litigation. No Indemnified Party
shall consent to entry of any judgment or enter into any settlement without the
consent of each Indemnifying Party.

                 2.6.4    If the indemnification provided for in this Section
is unavailable to an Indemnified Party in respect of any losses, claims,
damages or liabilities referred to therein, then each Indemnifying Party, in
lieu of indemnifying such Indemnified Party, shall contribute to the amount
paid or payable by such Indemnified Party as a result of such losses, claims,
damages or liabilities (i) in such proportion as is appropriate to reflect the
relative benefits received by the Company on the one hand and all shareholders
offering securities in the offering (the "Selling Security Holders") on the
other from the offering of the Company's securities, or (ii) if the allocation
provided by clause (i) above is not permitted by applicable law, in such
proportion as is appropriate to reflect not only the relative benefits referred
to in clause (i) above but also the relative fault of the Company on the one
hand and the Selling Security Holders on the other in connection with the
statements or omissions which resulted in such losses, claims, damages or
liabilities, as well as any other relevant equitable considerations. The
relative benefits received by the Company on the one hand and the Selling
Security Holders on the other shall be the net proceeds from the offering
(before deducting expenses) received by the Company on the one hand and the
Selling Security Holders on the other. The relative fault of the Company on the
one hand and the Selling Security Holders on the other shall be determined by
reference to, among other things, whether the untrue or alleged untrue
statement of material fact or the omission or alleged omission to state a
material fact relates to information supplied by the Company or by the Selling
Security Holders and the parties' relevant intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The Company and the Selling Security Holders agree that it would not be just
and equitable if contribution pursuant to this Section were based solely upon
the number of entities from whom contribution was requested or by any other
method of allocation which does not take account of the equitable
considerations referred to above in this Section. The amount paid or payable by
an Indemnified Party as a result of the losses, claims, damages and liabilities
referred to above in this Section shall be deemed to include any legal or other
expenses reasonably incurred by such Indemnified Party in connection with
investigating or defending any such action or claim, subject to the provisions


                                     -6-
<PAGE>   7
hereof. Notwithstanding the provisions of this Section, no Selling Shareholder
shall be required to contribute any amount or make any other payments under
this Agreement which in the aggregate exceed the proceeds received by such
Selling Shareholder. No person guilty of fraudulent misrepresentation (within
the meaning of the Securities Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation.

         2.7     Certain Information.

                 2.7.1    The holders of Registrable Securities agree, with
respect to any Registrable Securities included in any registration, to furnish
to the Company such information regarding such holder, the Registrable
Securities and the distribution proposed by the such holder as the Company may
reasonably request in writing and as shall be required in connection with any
registration, qualification or compliance referred to herein.

                 2.7.2    The failure of the holder of Registrable Securities
to furnish the information requested pursuant to Section 2.7.1 shall not affect
the obligation of the Company to the other Selling Security Holders who furnish
such information unless, in the reasonable opinion of counsel to the Company or
the underwriters, such failure impairs or may impair the legality of the
Registration Statement or the underlying offering.

         2.8     Rule 144 Reporting. With a view to making available the
benefits of certain rules and regulations of the Commission which may at any
time permit the sale of Restricted Securities (used herein as defined in Rule
144 under the Securities Act) to the public without registration, the Company
agrees to use its best lawful efforts to:

                 2.8.1    Make and keep public information available, as those
terms are understood and defined in Rule 144 under the Securities Act, at all
times during which the Company is subject to the reporting requirements of the
Securities Exchange Act of 1934, as amended (the "Exchange Act");

                 2.8.2    File with the Commission in a timely manner all
reports and other documents required of the Company under the Securities Act
and the Exchange Act (at all times during which the Company is subject to such
reporting requirements); and

                 2.8.3    So long as any holder of Registrable Securities owns
any Restricted Securities (as defined in Rule 144 promulgated under the
Securities Act), to furnish to such holder forthwith upon request a written
statement by the Company as to its compliance with the reporting requirements
of said Rule 144 and with regard to the Securities Act and the Exchange Act (at
all times during which the Company is subject to such reporting requirements),
a copy of the most recent annual or quarterly report of the Company, and such
other reports and documents of the Company and other information in the
possession of or reasonably obtainable by the Company as such holder of
Registrable Securities may reasonably request in availing itself of any rule or
regulation of the Commission allowing such holder to sell any such securities
without registration.

         2.9     Transferability. The rights conferred by this Agreement shall
be freely transferable to a recipient of Registrable Securities.

         2.10    Governing Law. This Agreement shall be governed in all respects
by the laws of the State of Delaware.


                                     -7-
<PAGE>   8
         2.11    Entire Agreement, Amendment. This Agreement constitutes the
full and entire understanding and agreement between the parties with regard to
the subject hereof. This Agreement, or any provision hereof, may be amended,
waived, discharged or terminated upon the written consent of the Company and
the Purchaser.

         2.12    Notices, etc. All notices and other communications required or

77042, or at such other address as the Company shall have furnished to the
Purchaser. Each such notice or other communication shall for all purposes of
this Agreement be treated as effective upon receipt.

         2.13    Delays or Omissions. Except as expressly provided herein, no
delay or omission to exercise any right, power or remedy accruing to any party
to this Agreement shall impair any such right, power or remedy of such party
nor shall it be construed to be a waiver of any such breach or default, or an
acquiescence therein, or of or in any similar breach or default thereafter
occurring; nor shall any waiver of any single breach or default be deemed a
waiver of any other breach or default theretofore or thereafter occurring. Any
waiver, permit, consent or approval of any kind or character on the part of any
party of any breach or default under this Agreement, or any waiver on the part
of any party of any provisions or conditions of this agreement, must be in
writing and shall be effective only to the extent specifically set forth in
such writing. All remedies, either under this Agreement or by law or otherwise
afforded to any party to this Agreement, shall be cumulative and not
alternative.

         2.14    Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be enforceable against the parties actually
executing such counterparts, and all of which together shall constitute one
instrument.

         2.15    Severability. In the event that any provision of this
Agreement becomes or is declared by a court of competent jurisdiction to be
illegal, unenforceable or void, this Agreement shall continue in full force and
effect without said provision.

         2.16    Titles and Subtitles. The titles and subtitles used in this
Agreement are used for convenience only and are not considered in construing or
interpreting this Agreement.

of the creditworthiness, financial condition or operations of any Borrower, or
of Borrowers as a whole.

acceptance in the event this Facility is not consummated on or before July 15,
1997 this approval confirmation shall automatically terminate without notice
unless extended by mutual agreement in writing. By accepting this letter,
Borrowers agree to pay all out-of-pocket costs and expenses incurred by Lender

limitation, reasonable at attorneys' fees and costs in preparation of this
