PART I



|ITEM 1. | BUSINESS
|------- | --------

General

Watsco, Inc. and its subsidiaries (collectively, Watsco, which may be referred to as we, us or our) was incorporated in 1956 and is the
largest distributor of air conditioning, heating, and refrigeration equipment and related parts and supplies (HVAC) in the United States. We presently operate from 380 locations in 32 states. Our revenues have increased from $80 million
in 1989 to over $1.8 billion in 2006 via a strategy of acquiring companies with established market positions and subsequently building revenue and profit growth from a combination of adding locations, products, services and other initiatives.

Our principal executive offices are located at 2665 South Bayshore Drive, Suite 901, Coconut Grove, Florida 33133, and our telephone number is
(305) 714-4100. Our website address on the Internet is www.watsco.com and e-mails may be sent to info@watsco.com.

Residential Central Air
Conditioning, Heating and Refrigeration Industry

The HVAC distribution industry is highly fragmented with over 1,300 distribution companies. The
industry is well-established having its primary period of growth during the post-World War II era with the advent of affordable central air conditioning and heating systems for residential applications.

Based on data published by the Air Conditioning and Refrigeration Institute (ARI), the Gas Appliance Manufacturers Association and other available data, we
estimate the market for residential central air conditioning, heating and refrigeration equipment and related parts and supplies in the United States is approximately $26 billion with unitary equipment shipments having grown at a compounded annual
rate of 3.4% since 1996. Residential central air conditioners are manufactured primarily by seven major companies that together account for approximately 90% of all units shipped in the United States each year. These companies are: Carrier
Corporation (Carrier), a subsidiary of United Technologies Corporation, Goodman Manufacturing Corporation (Goodman), Rheem Manufacturing Company (Rheem), American Standard Companies Inc. (American
Standard), York International Corporation (York), a subsidiary of Johnson Controls, Inc., Lennox International, Inc. (Lennox) and Nordyne Corporation (Nordyne), a subsidiary of Nortek Corporation. These
manufacturers distribute their products through a combination of factory-owned and independent distributors who, in turn, supply the equipment and related parts and supplies to contractors and dealers nationwide that sell to and install the products
for the consumer.

Residential central air conditioning and heating equipment is sold to both the replacement and the homebuilding markets. The replacement
market has increased substantially in size and importance over the past several years as a result of the aging of the installed base of residential central air conditioners and furnaces, the introduction of new energy efficient models, the
remodeling and expansion of existing homes, the addition of central air conditioning to homes that previously had only heating products and the consumers overall unwillingness to live without air conditioning or heating products. According to
industry data published by the Air Conditioning & Refrigeration Institute, over 100 million central air conditioning units and furnaces have been installed in the United States in the past 20 years. Many units installed during this period
have reached the end of their useful lives, thus providing a growing and substantial replacement market. The mechanical life of central air conditioning and furnaces varies by geographical region due to usage and is estimated to range from 8 to 20
years.

We also sell products to the refrigeration market. Such products include condensing units, compressors, evaporators, valves, refrigerant, walk-in
coolers and ice machines for industrial and commercial applications. We distribute products manufactured by Copeland Compressor Corporation, a subsidiary of Emerson Electric Co., E. I. Du Pont De Nemours and Company, Tecumseh Products Company and
The Manitowoc Company, Inc.

Business Strategy

We have
a proven buy and build strategy for long-term growth. The buy component of the strategy focuses on acquiring market leaders at attractive valuations, either expanding into new geographic areas or gaining further market share
in existing markets. We follow a disciplined, conservative approach that looks for opportunities that fit well-defined financial and strategic criteria. The build component of the strategy is focused on the institution of a growth
culture at acquired companies, the addition of products and locations to better serve our customers, the exchange of ideas and business concepts amongst the executive management team and

investing in new technology as a competitive advantage. Newly acquired businesses are able to access our capital resources and established vendor
relationships to provide an expanded array of product lines on the most favorable terms and conditions with an intensified commitment to service.

Strategy in Existing Markets

Our strategy for growth in existing markets focuses on customer service and product expansion to satisfy the
needs of the higher growth, higher margin replacement market, where customers generally demand immediate, convenient and reliable service. In response to this need, our focus is to (i) offer broad product lines, including the necessary
equipment, parts and supplies to enable a contractor to install or repair a central air conditioner, furnace or refrigeration system, (ii) maintain multiple warehouse locations for increased customer convenience, (iii) maintain
well-stocked inventories to ensure that customer orders are filled in a timely manner, (iv) provide a high degree of technical expertise at the point of sale and (v) develop and implement technological strategies to further enhance
customer service capabilities. We believe these concepts provide a competitive advantage over smaller, less-capitalized competitors who are unable to commit resources to open additional locations, implement technological business solutions, provide
the same variety of products, maintain the same inventory levels or attract the wide range of expertise that is required to support a diverse product offering. We also believe that in some geographic areas we have a competitive advantage over
factory-operated distributor networks who typically do not maintain as diversified inventories of parts and supplies and whose fewer number of warehouse locations make it more difficult to meet the time-sensitive demands of the replacement market.

In addition to the replacement market, we sell to the homebuilding market, including both traditional site-built homes and manufactured housing. We
believe our reputation for reliable, high-quality service and relationships with contractors, who may serve both the replacement and new construction markets, allow us to compete effectively in these markets.

Acquisition Strategy

Our acquisition strategy is focused on
acquiring businesses that complement our current presence in existing markets or establishing a presence in new markets. Since 1989, we have acquired 51 HVAC distribution businesses, four of which currently operate as primary operating subsidiaries.
The other smaller distributors acquired have been integrated into or are under the management of the primary operating subsidiaries. We continue to pursue additional strategic acquisitions to allow further penetration in existing markets and expand
into new geographic markets.

Product Line Expansion

We actively seek new or expanded territories of distribution from the key equipment suppliers. Significant relationships currently exist with Rheem, Carrier, Nordyne, Goodman, American Standard and Lennox. We continually evaluate new parts
and supply products to support equipment sales and further enhance service to our customers. The initiative includes increasing the product offering with existing vendors and identifying new product opportunities through traditional and
non-traditional supply channels. We have also introduced private-label products as a means to obtain market share and grow revenues. We believe that the private-label brand products complement the existing offerings at the selected locations based
on their particular market position, price-point and customer needs.

Operating Philosophy

Our subsidiaries operate in a manner that recognizes the long-term relationships established between the distributors and their customers. Generally, the identity and
culture of acquired businesses continue by retaining their historical trade-name, management team and sales organization, and by continuing the product brand-name offerings. We believe this strategy builds on the value of the acquired operations by
creating additional sales opportunities and is an attractive exit strategy for the existing ownership of the long-standing distribution companies targeted for acquisition.

A specialized functional support staff is maintained at our corporate headquarters to support the subsidiaries strategies for growth in their respective markets. Such functional support includes specialists in
finance, accounting, product procurement, treasury and working capital management, tax planning, risk management and safety. Certain general and administrative expenses are targeted for cost savings that leverage the overall business volume and
improve operating efficiencies.

Technology

Our
technology initiatives include: (i) implementation of effective point-of-sale systems that allow timely and effective customer service, including up-to-date pricing and inventory availability, (ii) enabling connectivity with our suppliers
and by our customers to the relevant components of our subsidiaries business software and (iii) a web site, ACDoctor.com, which provides homeowners and businesses useful information and a variety of services.

DESCRIPTION OF BUSINESS

Products

Watsco sells an expansive line of products and maintains a diverse mix of inventory to meet its
customers immediate needs and seeks to provide products a contractor would generally require when installing or repairing a central air conditioner, furnace or refrigeration system. The cooling capacity of air conditioning units is measured in
tons. One ton of cooling capacity is equivalent to 12,000 BTUs and is generally adequate to air condition approximately 500 square feet of residential space. The products we distribute consist of: (i) equipment, including residential central
air conditioners ranging from 1-1/2 to 5 tons, light commercial air conditioners ranging up to 20 tons, gas, electric and oil furnaces ranging from 50,000 to 150,000 BTUs, commercial air conditioning and heating equipment and systems ranging from 5
to 25 tons, and other specialized equipment; (ii) parts, including replacement compressors, evaporator coils, motors and other component parts; and (iii) supplies, including thermostats, insulation material, refrigerants, ductwork, grills,
registers, sheet metal, tools, copper tubing, concrete pads, tape, adhesives and other ancillary supplies.

Sales of air conditioning and heating equipment
accounted for approximately half of our distribution revenues for both years ended December 31, 2006 and 2005; and sales of parts and supplies (currently sourced from over 600 vendors) comprised the other half of our revenues for both such
periods as well.

Distribution and Sales

We currently
operate from 380 locations, a vast majority of which are located in regions that we believe have favorable demographic trends. We maintain large inventories at each warehouse location, which is accomplished by transporting inventory between
locations daily and either directly delivering products to customers using one of our 826 trucks or by making products available for pick-up at the location nearest to the customer. Watsco has approximately 365 commissioned salespeople, averaging 11
years or more of experience in the air conditioning, heating and refrigeration distribution industry.

Markets

Watscos network serves 32 states from these 380 locations. Primary markets include (the number of locations in the state are in parentheses): Florida (75), Texas
(63), Georgia (34), California (30) and North Carolina (28). Locations also reside in Tennessee, South Carolina, Mississipi, Louisiana, Virginia, Alabama, Arizona, Massachusetts, Arkansas, Missouri, Kansas, Oklahoma, Iowa, Kentucky, Maine, New
Hampshire, New York, South Dakota, Connecticut, Maryland, Nebraska, Nevada, New Jersey, North Dakota, Rhode Island, Vermont and Illinois. Products are sold on an export-only basis to portions of Latin America and the Caribbean Basin. Export sales
are less than 1% of total revenues.

Customers and Customer Service

We sell to contractors and dealers who service the replacement and new construction markets for residential and light commercial central air conditioning, heating and refrigeration systems and we currently serve over
40,000 customers. No single customer in 2006, 2005 or 2004 represented more than 2% of consolidated revenues. We focus on providing products where and when the customer needs them, technical support by phone or on site as required, and quick and
efficient service at the locations. Increased customer convenience is also provided through e-commerce, which allows customers to access information on-line 24 hours a day, 7 days a week to search for desired products, verify inventory availability,
obtain pricing, place orders, check order status, schedule pickup or delivery times and make payments. We believe we successfully compete with other distributors primarily on the basis of an experienced sales organization, strong service support,
high quality reputation and broad product lines.

Key Equipment Suppliers

Significant relationships are maintained with Rheem, Carrier, Nordyne, Goodman, American Standard and Lennox, each a leading manufacturer of residential central air conditioning and heating equipment in the United
States. Each manufacturer has a well-established reputation of producing high-quality, competitively priced products. The manufacturers current product offerings, quality, serviceability and brand-name recognition allow us to operate favorably
against our competitors. To maintain brand-name recognition, the manufacturers provide national advertising and participate with us in cooperative advertising programs and promotional incentives that are targeted to both contractors and end-users.
It is estimated that the replacement market currently accounts for approximately two-thirds of industry sales in the United States and is expected to increase as units installed in the past 20 years wear out and get replaced or updated to more
energy-efficient models.

Approximately 47%, 48% and 45% of purchases in 2006, 2005 and 2004, respectively, were made from the seven key equipment
suppliers. The largest supplier accounted for 17% of all purchases made in each of the years ended 2006, 2005 and 2004. A

significant interruption in the delivery of these products could impair our ability to continue to maintain current inventory levels and could adversely
affect our financial results. Future financial results are also materially dependent upon the continued market acceptance of these manufacturers products and their ability to continue to manufacture products that comply with laws relating to
environmental and efficiency standards.We believe that sales of other complementary equipment products and continued emphasis to expand sales of parts and supplies are mitigating factors against such risks.

Distribution Agreements

Distribution agreements have been executed
with six key equipment suppliers, either on an exclusive or non-exclusive basis, for terms generally ranging from one to ten years. Certain of the distribution agreements contain provisions that restrict or limit the sale of competitive products in
the markets served. Other than the markets where such restrictions and limitations may apply, we may distribute other manufacturers lines of air conditioning or heating equipment.

Seasonality

Sales of residential central air conditioners, heating equipment and parts and supplies have
historically been seasonal. See Business Risk Factors in Item 1A.

Competition

We operate in highly competitive environments. See Business Risk Factors in Item 1A.

Employees

There were approximately 3,300 employees as of December 31, 2006, substantially all of which are
non-union employees. Most of these employees are employed on a full-time basis, and relations with employees are good.

Order Backlog

Order backlog is not a material aspect of the business and no material portion of the business is subject to government contracts.

Government Regulations, Environmental and Health and Safety Matters

Our industry and business are subject to federal, state and local laws and regulations relating to the generation, storage, handling, emission, transportation and discharge of materials into the environment. These include laws and
regulations implementing the Clean Air Act, relating to minimum energy efficiency standards of HVAC systems and the production, servicing and disposal of certain ozone-depleting refrigerants used in such systems, including those established at the
Montreal Protocol in 1992 concerning the phase-out of CFC-based refrigerants on products manufactured after January, 2010. We are also subject to regulations concerning the transport of hazardous materials, including regulations adopted pursuant to
the Motor Carrier Safety Act of 1990. Our operations are also subject to health and safety requirements including the Occupational, Safety and Health Act (OSHA). Management believes that the business is operated in substantial compliance with all
applicable federal, state and local provisions relating to the protection of the environment, transport of hazardous materials and health and safety requirements.

Our industry and business was also subject to a Department of Energy mandate that required, effective January 23, 2006, that our key equipment suppliers manufacture products with a higher standard of energy efficiency. Prior to
January 23, 2006, the minimum standard for energy efficiency as measured by industry guidelines was 10 SEER (seasonal energy efficiency rating, the metric used to measure energy efficiency). On the effective date, the new standard increased the
minimum allowed efficiency to 13 SEER (a 30% improvement in efficiency). The transition of products from the current standard to the new standard took place during 2006, as 13 SEER products were introduced and became fully available to consumers.

Non-U.S. Operations

All of our operations are within
the United States. We do not have any international operations. Export sales are less than 1% of total revenues.

|ITEM 1A. | RISK FACTORS
|-------- | ------------

Business Risk Factors

Supplier Concentration

We maintain distribution agreements with the
key equipment suppliers, either on an exclusive or non-exclusive basis, for terms generally ranging from one to ten years. Certain of the distribution agreements contain provisions that restrict or limit the sale of competitive products in the
markets served. Other than the markets where such restrictions and limitations may apply, we may distribute other manufacturers lines of air conditioning or heating equipment. Purchases from these suppliers comprised 47% of all purchases made
in 2006 with the largest supplier accounting for 17% of all purchases made in 2006. Any significant interruption by the manufacturers or a termination of a distribution agreement could temporarily disrupt the operations of certain subsidiaries.
Future results of operations are also materially dependent upon the continued market acceptance of these manufacturers products and their ability to continue to manufacture products that comply with laws relating to environmental and
efficiency standards.

Competition

We operate in
highly competitive environments. We compete with a number of distributors and also with several air conditioning and heating equipment manufacturers that distribute a significant portion of their products through their own distribution organizations
in certain markets. Competition within any given geographic market is based upon product availability, customer service, price and quality. Competitive pressures or other factors could cause our products or services to lose market acceptance or
result in significant price erosion, all of which would have a material adverse effect on profitability.

Seasonality

Sales of residential central air conditioners, heating equipment and parts and supplies have historically been seasonal. Furthermore, profitability can be impacted
favorably or unfavorably based on the severity or mildness of weather patterns during summer or winter selling seasons. Demand related to the residential central air conditioning replacement market is highest in the second and third

##### Table of Contents

quarters with demand for heating equipment usually highest in the fourth quarter. Demand related to the new construction sectors throughout most of the
markets is fairly even during the year except for dependence on housing completions and related weather and economic conditions.

Risks Inherent in
Acquisitions

As part of our strategy, we intend to pursue additional acquisitions of complementary businesses. If we complete future acquisitions, we
may be required to incur or assume additional debt and/or issue additional shares of our common stock as consideration, which will dilute our existing stockholders ownership interest and may affect our results of operations. Growth through
acquisitions involves a number of risks, including the following:



| |  |  | the ability to identify and consummate complementary acquisition candidates;
| | - |  | ----------------------------------------------------------------------------



| |  |  | the successful operation and/or integration of acquired companies in an effective manner;
| | - |  | -----------------------------------------------------------------------------------------



| |  |  | diversion of managements attention from other daily functions;
| | - |  | ---------------------------------------------------------------



| |  |  | issuance by us of equity securities that would dilute ownership of our existing stockholders;
| | - |  | ---------------------------------------------------------------------------------------------



| |  |  | incurrence and/or assumption of significant debt and contingent liabilities; and
| | - |  | --------------------------------------------------------------------------------



| |  |  | loss of key employees and/or customer relationships of the acquired companies.
| | - |  | ------------------------------------------------------------------------------

Dependence on Key Personnel

We are highly dependent on the skills, experience and services of key personnel. The
loss of key personnel could have a material adverse effect on our business, operating results or financial condition. Our potential growth and expansion are expected to place increased demands on our management skills and resources. Therefore, our
success also depends upon our ability to recruit, hire, train and retain additional skilled and experienced management personnel. Employment and retention of qualified personnel is important due to the competitive nature of our industry.

General Risk Factors

Goodwill and Intangibles

At December 31, 2006, goodwill and intangibles represented approximately 23% of total assets. Goodwill and indefinite life intangibles are no longer amortized and
are subject to impairment testing at least annually using a fair value based approach. The identification and measurement of impairment involves the estimation of the fair value of reporting units. Accounting for impairment contains uncertainty
because management must use judgment in determining appropriate assumptions to be used in the measurement of fair value. The estimates of fair value of reporting units are based on the best information available as of the date of the assessment and
incorporate management assumptions about expected future cash flows and contemplate other valuation techniques. Future cash flows can be affected by changes in industry or market conditions.

The recoverability of goodwill and indefinite life intangibles is evaluated at least annually and when events or changes in circumstances indicate that the carrying
amount of goodwill and indefinite life intangibles may not be recoverable. Although no impairment has been recorded to date, there can be no assurances that future impairments will not occur.

Risks Related to Insurance Coverage

We carry general liability,
comprehensive property damage, workers compensation and other insurance coverages that management considers adequate for the protection of its assets and operations. There can be no assurance, however, that the coverage limits of such policies
will be adequate to cover losses and expenses for lawsuits brought or which may be brought against us. A loss in excess of insurance coverages could have a material adverse effect on our financial position and/or profitability. Certain
self-insurance risks for casualty insurance programs and health benefits are retained and reserves are established based on claims filed and estimates of claims incurred but not yet reported. Assurance cannot be provided that actual claims will not
exceed present estimates. Exposure to catastrophic losses has been limited by maintaining excess and aggregate liability coverages and implementing loss control programs.

Control by Existing Shareholder

As of December 31, 2006, Albert H. Nahmad, Watscos Chairman and Chief
Executive Officer, and a limited partnership controlled by him, collectively had beneficial ownership of approximately 57% of the combined voting power of the outstanding Common stock and Class B common stock. Based on Mr. Nahmads stock
ownership and the stock ownership of the limited partnership controlled by him, Mr. Nahmad has the voting power to elect all but three members of the nine-person Board of Directors and to control most corporate actions requiring shareholder
approval.

Information about Forward-Looking Statements

This Form 10-K contains or incorporates by reference statements that are not historical in nature and that are intended to be, and are hereby identified as, forward-looking statements as defined in the
Private Securities Litigation Reform Act of 1995, including statements regarding, among other items, (i) business and acquisition strategies, (ii) potential acquisitions, (iii) financing plans and (iv) industry, demographic and
other trends affecting Watscos financial condition or results of operations. These forward-looking statements are based largely on managements current expectations and are subject to a number of risks, uncertainties and changes in
circumstances, certain of which are beyond their control.

Actual results could differ materially from these forward-looking statements as a result of
several factors, including:



| |  |  | general economic conditions affecting general business spending,
| | - |  | ----------------------------------------------------------------



| |  |  | consumer spending,
| | - |  | ------------------



| |  |  | consumer debt levels,
| | - |  | ---------------------



| |  |  | seasonal nature of product sales,

| |  |  | competitive factors within the HVAC industry,
| | - |  | ---------------------------------------------



| |  |  | insurance coverage risks,
| | - |  | -------------------------



| |  |  | prevailing interest rates, and
| | - |  | ------------------------------



| |  |  | the continued viability of Watscos business strategy.
| | - |  | ------------------------------------------------------

In light of these uncertainties, there can be no assurance that the forward-looking information contained herein will be realized or, even if substantially realized, that the information will have the expected consequences to or effects on
Watsco or its business or operations. A discussion of certain of these risks and uncertainties that could cause actual results to differ materially from those predicted in such forward-looking statements is included in Watscos Annual Report to
Shareholders for the fiscal year ended December 31, 2006 in the section captioned Managements Discussion and Analysis of Financial Condition and Results of Operations, which section has been incorporated in the Form 10-K by
reference. Forward-looking statements speak only as of the date the statement was made. Watsco assumes no obligation to update forward-looking information or the discussion of such risks and uncertainties to reflect actual results, changes in
assumptions or changes in other factors affecting forward-looking information.



|ITEM 1B. | UNRESOLVED STAFF COMMENTS
|-------- | -------------------------

None.



|ITEM 2. | PROPERTIES
|------- | ----------

Our main properties include warehousing and
distribution facilities, trucks and administrative office space.

Warehousing and Distribution Facilities

At December 31, 2006, we operated 380 warehousing and distribution facilities across 32 states in the United States having approximately 7.9 million square feet
of space in the aggregate of which approximately 7.5 million square feet is leased. The majority of these leases are for terms of three to five years. We believe that our facilities are generally sufficient to meet our present operating needs.

Trucks

At December 31, 2006, we operated 826
ground transport vehicles, including delivery and pick-up trucks, vans and tractors. Of this number, 534 trucks were leased and the rest were owned. We believe that the present size of our truck fleet is adequate to support our operations.

Administrative and Other Properties and Facilities

Senior management and a functional support staff is located at Watscos corporate headquarters in Coconut Grove, Florida in approximately 6,000 square feet of owned space. In addition to the corporate headquarters, we also have 11
other locations, with an aggregate of approximately 25,000 square feet, all of which are leased. The majority of these leases are for terms of three to five years.

During 2006, our capital expenditures were $10 million.

|ITEM 3. | LEGAL PROCEEDINGS
|------- | -----------------

We are involved in litigation incidental to the
operation of our business. We vigorously defend all matters in which Watsco or its subsidiaries are named defendants and, for insurable losses, maintain significant levels of insurance to protect against adverse judgments, claims or assessments.
Although the adequacy of existing insurance coverage or the outcome of any legal proceedings cannot be predicted with certainty, we do not believe the ultimate liability associated with any claims or litigation will have a material impact to our
financial condition or results of operations.

Performance Graph

The following graph compares the cumulative 5-year total return attained by shareholders on Watsco,
Inc.s Common stock and Class B common stock relative to the cumulative total returns of the AMEX Composite index, the S & P Smallcap 600 index and two customized peer groups of companies that includes a new peer group of six companies,
which are: Beacon Roofing Supply Inc, Goodman Global Inc, Interline Brands Inc, Lennox International Inc, Pool Corp. and Wesco International Inc; and the old peer group of one company which is ACR Group Inc. We determined to use the new peer group
this year because we believe that the new peer group more closely reflects our business and, as a result, provides a more meaningful comparison of stock performance. In accordance with Securities and Exchange Commission rules, the graph includes
both the old peer group and the new peer group. An investment of $100 (with reinvestment of all dividends) is assumed to have been made in our common stock, in each index and in each of the peer groups on 12/31/2001 and its relative performance is

us or on our behalf by any affiliated purchaser (as such term is defined in Rule 10b-18(a)(3) of the Securities Act of 1933, as amended).

Recent Sales of Unregistered Securities

No sales of unregistered securities were made during the fourth quarter of the year ended
December 31, 2006.

Dividends

Cash dividends of
$.95 per share, $.62 per share and $.38 per share of Common stock and Class B common stock were paid in 2006, 2005 and 2004, respectively. In February 2007, Watscos Board of Directors approved an increase in the quarterly cash dividend to 33
cents per share from 25 cents per share. Future dividends will be at the sole discretion of the Board of Directors and will depend upon such factors as profitability, financial condition, cash requirements, restrictions existing under the debt

Evaluation of Disclosure Controls and
Procedures

Our Chief Executive Officer, Senior Vice President and Chief Financial Officer have evaluated the effectiveness of Watscos
disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 (the Exchange Act)) as of December 31, 2006, and each has concluded that such disclosure controls
and procedures are effective to ensure that information required to be disclosed in our periodic reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in Securities and
Exchange Commissions rules and regulations.

Managements Report on Internal Control Over Financial Reporting

Pages 18 and 21 of the 2006 Annual Report contain Managements Report on Internal Control Over Financial Reporting and the report thereon of Grant
Thornton LLP dated March 1, 2007, and are incorporated herein by reference.

Changes in Internal Control Over Financial Reporting

We are continuously seeking to improve the efficiency and effectiveness of our operations and of our internal controls. This results in refinements to
processes throughout the Company. However, there have been no changes in internal controls over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended December 31, 2006,
that have materially affected, or are reasonably likely to materially affect, Watscos internal controls over financial reporting.
