                                     PART I
 
ITEM 1. BUSINESS
 
    GENERAL
 
    The Company is a construction materials company focusing primarily on
products for roofing, sealing and paving applications. The Company develops,
manufactures and markets several separate but related product lines including
roof and driveway coatings and paving products, industrial emulsions, air
barriers, polyurethane foam for roofing and commercial uses, sealants for
construction and marine uses and specialty products.
 
    Beginning in 1988, the Company's management focused on expanding the Henry
brand from its Southern California base initially through the acquisition of
regional roof coatings manufacturers and distributors in contiguous regions--the
Southwest, the Northwest, Northern California and the Rocky Mountain region. In
1998, the Company became a national organization by acquiring Monsey Bakor,
which has served the U.S. and Canadian markets for over 50 years as a leading
manufacturer and distributor of a broad spectrum of building products for
residential and commercial use with a product line consisting of roof coatings,
adhesives and membranes, roofing and air barrier systems as well as specialized
industrial emulsions.
 
    DIVISIONS
 
    The Company's two major divisions are the Henry Coatings Division and the
Resin Technology Division.
 
    HENRY COATINGS DIVISION
 
    The Henry Coatings Division, which accounted for the bulk of the Company's
1998 net sales, develops, manufactures and markets coatings, sealants and
membranes for construction, industrial, building materials and other specialty
applications. The Company also manufactures wax-based emulsions for the gypsum
industry.
 
    PRODUCTS
 
    Roofing products represent the majority of the Coatings Division's total
revenues. Henry's roofing products are designed to address the problems of water
invasion, wind erosion and ultraviolet damage. Henry offers a full line of
liquid roof coatings and adhesives including both solvent and water-based
products. In addition to roof coatings and mastics, Henry manufactures
high-quality modified bitumen roofing membrane products (SBS) designed to be
used in roofing systems that can meet the challenge of the elements encountered
throughout North America.
 
    The Company offers a full line of reflective coatings designed to improve
roof aesthetics and aid in the conservation of energy through their reflective
qualities. Henry's reflective coatings product line includes both white acrylic
and solvent-based coatings and high-quality aluminum products and the
accessories needed to protect roofs for years.
 
    Henry's industrial emulsions are used as coating, sizing, strengthening and
moisture-proofing additives by manufacturers of fiber products such as gypsum
wallboard, insulation board, gaskets, paper board, and glass fibers. The
Company's primary emulsion product, wax-based industrial emulsions, are
specifically used by manufacturers of gypsum wallboards. Sales of industrial
emulsions have increased in recent years partially due to increased
environmental restrictions on volatile organic compound emissions, which has
created a demand for emulsion-based products over solvent-based products. The
Company's wax-based emulsions are manufactured with proprietary and patented
processes that management believes contributes to higher margins relative to
those of competitors.
 
                                       2
<PAGE>
    Driveway maintenance and paving products manufactured by Henry are used for
the asphalt highway market and the preventative maintenance of asphalt parking
lots and driveways. Henry Company produces polymerized asphalt, an asphalt
binder that is a key ingredient of paving asphalts.
 
    The Company's air barrier systems are designed to reduce air flows through
exterior walls of buildings. The movement of air into a building (infiltration)
and out of a building (exfiltration) is caused by pressure differences produced
by wind, chimney effect and pressurization. If air flows through a building and
exfiltrates, it can deposit moisture on the cold masonry cladding, causing brick
or stone to undergo major changes due to moisture absorption. This dampness can
cause dimensional changes and accelerate the deterioration process.
Moisture-laden air from a humidified building can also develop into ice under
freezing conditions, causing displacement of the exterior masonry cladding,
corrosion, and lower energy efficiency. The advantage of the Company's
prefabricated modified bitumen sheet is that it provides a flexible air barrier
membrane capable of bridging construction gaps and absorbing deflection. The
Company's line of air barriers can be installed into existing buildings on
either internal or external walls or used in the construction of new buildings.
In 1986, Canada required air barriers in all buildings as an amendment to the
National Building Code. In the United States, however, there is no national
standard and the air barrier market remains in its infancy.
 
    The Company's specialty products include protective coatings for a variety
of industrial and commercial applications, such as specialty asphalt coatings to
protect wood, metal, mortar or thermal insulation. The Company manufactures
undercoatings for mobile homes, as well as both solvent and water-based
rust-proofing products for the automobile industry. The Company also produces a
broad range of paint products for interior and exterior use and a number of
coatings for wood preservation and agricultural purposes.
 
    The Company's sealant line has three distinct product categories: sealants
for construction applications, hatch cover sealants for ocean freighters, and
preformed adhesive waterstops for expansion joint applications on construction
projects. Products include a preformed plastic gasket for precast concrete
structures, which provides watertight sealing for joints such as those on
underground concrete drainage and manhole structures. These products are also
used for sealing hatch covers on ships to prevent water damage to cargoes that
can occur in heavy seas. There is also a preformed plastic adhesive waterstop
which is used as a construction joint sealant in poured-in-place concrete
structures. Henry Company believes this product allows for an easier, more
reliable and more efficient sealing method than the traditional PVC-type
waterstop.
 
    MANUFACTURING
 
    For purposes of organizing its manufacturing process, the Company uses seven
related product groups. The product groups are: cold applied liquid coatings,
cements and adhesives; asphalt, coal tar and wax emulsions; acrylic-based roof
and insulation coatings; hot melt rubberized asphalt roofing and waterproofing
products; styrene-butadiene-styrene ("SBS") modified bitumen membranes, air
barrier and waterproofing membranes; specialty adhesives; and specialty
preformed asphaltic tapes. The facilities at which these products are produced
are shown in Item 2 ("Properties").
 
    The key materials used in the production of roofing and pavement products
are asphalt, mineral spirits, various fibers, resins, and polyester and glass
matting. For the production of industrial emulsions, the primary material is
refined wax. These raw materials are generally available on a regional basis and
supply disruptions are very rare. The Company maintains multiple sourcing
arrangements for all of its key materials and has experienced low price
volatility over the past several years. In addition to raw materials, packaging
supplies represent a meaningful portion of production cost.
 
    The Company, like many of its competitors, uses fibers such as chrysotile
asbestos in its production process. Management believes that its use of
chrysotile asbestos is in accordance with regulations of the Occupational Safety
and Health Administration ("OSHA"). OSHA requires that chrysotile asbestos
fibers
 
                                       3
<PAGE>
not be exposed to an open-air environment. In the Company's production process,
the cellulose or chrysotile asbestos fiber is pumped through a negative pressure
fluffer that separates the fibers for optimal dispersion in the product mixture.
The fibers are then mixed into and fully encapsulated by the asphalt. Once
encapsulated the fibers are "locked" into the asphalt cutback and cannot be
physically separated from the product. OSHA and other regulatory bodies have
determined that encapsulation renders the chrysotile asbestos harmless. The
Environmental Protection Agency ("EPA") does not regulate or enforce any special
procedures for the application of chrysotile asbestos-containing roof coatings
or sealants.
 
    Management believes that chrysotile asbestos-fibered roofing cements have
better application quality and durability as compared to those containing
chrysotile asbestos substitutes. The primary industries that currently continue
to use chrysotile asbestos are those manufacturing chrysotile asbestos-cement
pipe and shingles, automobile brake pads, gaskets and roof coatings and
sealants. Although chrysotile asbestos-cement pipe and shingles are no longer
manufactured in the United States, these products are still currently sold in
various parts of the country. Domestic manufacturers of brake pads, gaskets and
roof coatings used roughly 22,000 tons of chrysotile asbestos in 1996 because of
its strength, durability and heat resistance. Although some roofing products
manufacturers have switched to an exclusively non-asbestos line, some of the
leading firms in the industry continue to use asbestos in at least some of their
products.
 
    SALES, MARKETING AND DISTRIBUTION
 
    Due to the many products manufactured by the Henry Coatings Division, the
Company markets its products by focusing on four business segments. These
segments are: Retail; Industrial, Commercial and Institutional ("ICI");
Specialty Products; and International.
 
    The Retail segment is focused on selling products to national home center
chains, retail building material suppliers, hardware distributors, paint and
sundry distributors, farm and hardware cooperatives, and mass merchandisers. To
reach customers, the Company employs a trained sales organization and has an
in-house Creative Services Department which produces customized brochures and
promotional materials and coordinates national and regional advertising
programs.
 
    The ICI products are used by contractors throughout North America and sold
through both national and regional roofing distributors. Henry maintains a
technical selling staff engaged in both sales and training to help ensure that
the Company's products are applied properly.
 
    The Specialty Products segment markets a broad array of products using a
technical sales force trained to help customers in the use of the various
products. The two leading products in the Specialty Products segment are wax
emulsions and asphalt emulsions. Wax emulsions are sold to the gypsum wallboard
industry while major roofing companies are the primary market for asphalt
emulsions for use as a sizing agent in insulation board.
 
    The International segment is engaged in the sale of all Henry products to
the international market with special focus on the Company's basic product line
of roof coatings and cements and industrial emulsions.
 
    ROOFING SYSTEMS
 
    Henry Company has developed a roofing systems segment for one-stop
commercial roofing or re-roofing or roofing maintenance with warranty
protection. The Company's personnel work with architects, building owners and
contractors to develop custom specifications utilizing Henry products for the
design, construction and maintenance of commercial roofs. An important component
of the Company's roof systems program's success is that building owners are
assured that Henry Company will stand behind the roof from beginning to end. A
Henry Company sales consultant will write a custom specification for the roof
and the roofing system will be applied by a Henry Company-approved contractor
generally using Henry Company products. A Henry Company technical inspector will
inspect the roof application during
 
                                       4
<PAGE>
installation and regular follow-up inspections and in some instances maintenance
will be performed throughout the life of the warranty. Henry Company offers
20-year warranties on its reroofing systems and 5-year warranties on its
maintenance systems calculated on a fee per square-foot basis. Since its
inception, expenses for warranty claims experience has been very low. In part,
this is due to Henry Company's continuing inspection program. Management
believes that the roofing systems business represents a significant growth
opportunity.
 
    RESIN TECHNOLOGY DIVISION
 
    The Resin Technology Company ("RTC"), founded as an independent company in
1982 and now a division of the Company, produces polyurethane foam products for
roofing and other industrial applications. RTC also sells coating products
manufactured for it by third parties for application on foam. The acquisition of
RTC in 1988 has enabled the Company to offer a broader range of roofing products
to meet the needs of the commercial and residential roofing markets.
 
    PRODUCTS
 
    RTC's primary product categories are polyurethane foam and coatings.
Polyurethane foam has two liquid components, resin and hardener, which are mixed
together in a spray unit during application. A chemical reaction causes the
liquid to expand many times in thickness creating a rigid layer of closed-cell
foam. In roofing applications, this foam is strong enough to be walked on
minutes after the application. The result is a seamless barrier against water
penetration that is durable and easy to maintain. In roofing applications, an
elastomeric coating must be applied as protection against the sun's ultraviolet
radiation. RTC sells acrylic, urethane, silicone and polyurea coatings.
 
    RTC's products offer users several advantages, including a seamless barrier
that minimizes the likelihood of leaks and provides superior insulation
characteristics that can reduce energy costs. It is relatively light in weight
and is therefore particularly adaptable to large arenas or other structures that
may benefit from a lighter weight roof. Furthermore, it can be applied directly
over an existing roof, potentially avoiding the costly "tear-offs" that may be
required with other roofing systems.
 
    RTC's products are also used in a number of original equipment manufacturer
applications. The insulation and weight characteristics of polyurethane foam
make it an integral part of the thermal panel, spa and packaging industries,
among others.
 
    MANUFACTURING
 
    RTC manufactures all of its polyurethane foam products in its Ontario,
California manufacturing facility. Its polyurethane resin system is made up of
two components: a hardening agent that is purchased by the Company and resin
that is manufactured in the Ontario facility. Raw materials are automatically
pumped from one or more of the 11 raw material storage tanks within the
facility, blended and then poured into 55-gallon drums, tote capsules or bulk
tanker trucks. The production process is highly automated. The bulk of RTC's
coatings products for polyurethane foam applications are produced by a
third-party manufacturer also located in Ontario. The Company believes that it
derives its success in the polyurethane foam market from its superior
understanding of technology and the Company has secured a number of original
equipment manufacturer accounts because of its ability to produce products for a
customer's very specific technical requirements.
 
    SALES, MARKETING AND DISTRIBUTION
 
    The Resin Technology Company sells primarily to roofing contractors and
original equipment manufacturers in the western United States. RTC's roofing
products are sold directly to pre-qualified
 
                                       5
<PAGE>
contractors experienced in applying and spraying polyurethane foam onto roofs.
Sales to original equipment manufacturers include those to spa equipment
manufacturers, and management believes the Company is the leading supplier to
this market. RTC also supplies manufacturers in many other industries including
those producing freezer panels, thermal food transportation equipment, boat
floatation and packaging products. RTC's remaining sales are made to several
distributors, particularly in the Northwest and upper Midwest.
 
    RTC supports its sales efforts with a sales staff organized according to
market segment and regional location. Henry Company believes that RTC's
marketing advantages are based on a commitment to technical development and
customer support and also believes that RTC has captured a number of original
equipment manufacturer accounts from its competitors by efficiently responding
to the customer's technical requirements. In both the roofing and original
equipment manufacturer segments Henry Company provides just-in-time delivery
capability which is essential in time and labor-sensitive roofing applications.
 
EMPLOYEES
 
    As of December 31, 1998, Henry Company employed approximately 600 persons,
the majority of whom were involved in production and distribution, with the
balance engaged in administration, sales and clerical work. Of these employees,
approximately 485 were employed in the United States and 115 in Canada.
Approximately 48 employees located in Huntington Park, California, 31 employees
in Kimberton, Pennsylvania, 8 employees in Rock Hill, South Carolina, 28
employees in Ville St. Pierre, Quebec and 2 employees in Mirabel, Quebec are
unionized and covered by collective bargaining agreements. These collective
bargaining agreements expire on June 30, 2000, March 31, 2000, February 3, 2001,
June 30, 1999 and February 28, 2000, respectively. The Company believes that its
relationship with its employees is good. The Company has not experienced a work
stoppage at any of its facilities in over 20 years.
 
RISK FACTORS
 
SUBSTANTIAL LEVERAGE
 
    The Company has consolidated indebtedness that is substantial in relation to
the book value of its shareholders' equity. As of December 31, 1998, Henry
Company had approximately $87.6 million of debt (the sum of long-term debt,
including current maturities of long-term debt, notes payable and capitalized
lease obligations) and approximately $5.8 million book value of shareholders'
equity.
 
    The Company's significant borrowings have several important consequences for
the Company including but not limited to the following: (i) a substantial
portion of the Company's cash flow from operations must be dedicated to debt
service and will not be available for other purposes; (ii) the Company's ability
to obtain additional financing in the future for working capital, acquisitions
or capital expenditures may be significantly impaired and (iii) the Company's
substantial leverage may make it more vulnerable to economic downturns and limit
its ability to withstand competitive pressures or to take advantage of business
opportunities.
 
    The Company's ability to make cash payments to satisfy its debt obligations
will depend on its future operating performance, which will be affected by
financial, business, competitive, general economic and other factors, many of
which are beyond the Company's control. Based upon current levels of operations
and anticipated cost savings and future growth, the Company believes that its
expected cash flow from operations, together with available borrowings under its
credit facility and its other sources of liquidity, will be adequate to meet its
anticipated requirements for working capital, scheduled principal and interest
payments, lease payments and capital expenditures. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations--Liquidity and
Capital Resources".

ABILITY TO ACHIEVE ANTICIPATED COST SAVINGS OR REVENUE GROWTH
 
    Any statements concerning potential cost savings and revenue growth
contained in this annual report are forward-looking statements that are based on
estimates and assumptions made by the Company's management. Although believed to
be reasonable, such statements are inherently uncertain, and results are
difficult to predict. Therefore, undue reliance should not be placed upon such
statements. The following important factors, among others, could cause the
Company not to achieve the results contemplated herein or otherwise cause the
Company's business, financial condition or results of operations to be adversely
affected in future periods: (i) loss of key customers or continued or increased
competitive pressures; (ii) changes in customer spending levels; (iii)
unanticipated costs related to the acquisition of Monsey Bakor and the
integration of the companies; (iv) absence of inclement weather; (v) loss or
retirement of key members of management; (vi) increases in interest rates or the
Company's cost of borrowing or a default under any material debt agreement;
(vii) unavailability of funds for capital expenditures or research and
development; (viii) changes in governmental, environmental or other regulations
or (ix) changes in general economic conditions. Certain of these factors are
discussed in more detail elsewhere in this annual report. Given these
uncertainties, prospective investors are cautioned not to place undue reliance
on such forward-looking statements. The Company disclaims any obligation to
update factors or to publicly announce the result of any revisions to any of the
forward-looking statements contained herein to reflect future events or
developments.
 
FLUCTUATION OF RAW MATERIAL COST
 
    The Company utilizes a number of raw materials in its manufacturing
processes, some of which have historically fluctuated in price at particular
times. These price fluctuations have been based on such factors as the capacity
of the raw material supply chain, demand in the market, weather, general
economic factors and the availability of alternative raw materials. Raw
materials utilized by the Company that have historically experienced some price
fluctuation include asphalt, aluminum paste, rubber and certain diisocynates,
among others. For example, asphalt, which is a byproduct of crude oil refining,
has fluctuated in price with changes in worldwide crude oil prices and capacity
and with changes in the supply and demand in the oil, gasoline and fossil fuel
markets. Significant increases in asphalt prices or in the prices of other raw
materials, if not offset by product price increases, could have a material
adverse impact on the profit of the Company. There can be no assurance that the
Company will be able to pass any future cost increases through to its customers
in the form of price increases.
 
IMPACT OF WEATHER
 
    Because many of the Company's products are designed to patch or fix damaged
roofs, the Company's revenues are affected by weather conditions. Sales of
roofing products have historically tended to increase in areas which have
experienced severe weather. The results of severe weather or the anticipation of
severe weather may motivate property owners to undertake required roof
maintenance or to replace an old or worn roof. The absence of inclement weather
in some or all of the Company's markets could have an adverse impact on the
Company's business, financial condition or results of operations.
 
PRODUCT LIABILITY AND ASBESTOS LITIGATION
 
    The Company's business entails an inherent risk of product liability claims,
including a particular risk with respect to chrysotile asbestos-containing
products that the Company manufactures. Although some roofing products
manufacturers have switched to an exclusively non-asbestos line, some of the
leading firms in the industry continue to use chrysotile asbestos in at least
some of their products. The Company believes that its use of chrysotile asbestos
fibers, which are encapsulated by asphalt in the manufacturing process, is in
accordance with applicable laws. However, the Company has been named as a
defendant in suits alleging certain asbestos-related injuries. Although the
Company has not paid any amounts in judgment or settlement of any
asbestos-related claim to date, there can be no assurance that any such
 
                                       7
<PAGE>
claim will not in the future result in a material adverse judgment against, or
settlement by, the Company. Other than these asbestos-related claims, no
material product liability claims are currently pending against Henry Company.
However, there can be no assurance that such claims will not arise in the
future. The costs of defending the pending asbestos-related suits are currently
funded by a joint defense arrangement among the Company's insurance carriers and
the Company believes such insurance coverage is adequate. However, Henry Company
is not covered by insurance for asbestos-related claims for injuries that are
alleged to have arisen after 1985.
 
    The Company maintains product liability insurance for non-asbestos claims in
the amount of $21,000,000. However, there can be no assurance that the product
liability coverage maintained by the Company will be adequate to cover product
liability claims or that the applicable insurer will be solvent at the time of
any required payment. In addition, there can be no assurance that the Company
will be able to maintain its product liability coverage on current or otherwise
acceptable terms. A product liability or asbestos-related claim that results in
a judgment or settlement in excess of the Company's insurance coverage, or a
material judgment or settlement for an asbestos-related claim for injuries
alleged to have arisen after 1985, would have a material adverse effect on the
Company.
 
RELIANCE ON KEY PERSONNEL
 
    The Company's future success will depend to a significant extent on its
executive officers and other key management personnel. In addition, the success
of any acquisitions by the Company may depend, in part, on the Company's ability
to retain management personnel of the acquired companies. Although the Company
has employment agreements with several of its executive officers and key
personnel, including its President, Monsey Bakor's former Chairman of the Board
and the former President of Monsey Bakor's Canadian operations, there can be no
assurance that the Company will be able to retain its executive officers and key
personnel or attract additional qualified management in the future. Although the
Company is the beneficiary under key-person life insurance policies on the lives
of the Company's President and Chief Operating Officer and Monsey Bakor's former
Chairman of the Board (who has become a Vice Chairman of the Board and an
executive officer of the Company following the Acquisition), there can be no
assurance that the proceeds of these policies would be adequate to compensate
the Company for the loss of services due to the death of these individuals.
 
COMPETITION
 
    The roofing products and roofing systems industries are highly competitive
in most product categories and geographic regions. Competition is largely based
on quality, service, price and distribution capabilities. The Company competes
for retail and wholesale business with both large national manufacturers and
smaller regional producers. In certain circumstances, due primarily to factors
such as freight rates and customer preference for local brands, manufacturers
with better access to certain geographic markets may have a competitive
advantage in such markets. In addition, many of the Company's competitors within
the roofing products industry have greater financial, marketing, distribution,
management and other resources than the Company, and as the industry
consolidates, the Company's competitors may further enhance these resources. The
Company also believes that excess capacity in the roofing products and roofing
systems industry, especially during slow periods for the industry, could result
in downward pricing pressure and intensified competition. Given these factors,
there can be no assurance that the Company will be able to continue to compete
successfully against existing or new competitors, and the failure to do so would
have a material adverse effect on the Company's business, financial condition
and results of operations.
 
ENVIRONMENTAL MATTERS
 
    The past and present business operations of the Company and the past and
present ownership and operation of real property by the Company are subject to
extensive and changing federal, state, local and foreign environmental laws and
regulations pertaining to the discharge of materials into the environment,
 
                                       8
<PAGE>
the handling, storage, treatment and disposal of wastes (including solid and
hazardous wastes), the remediation of releases of toxic or hazardous materials
or otherwise relating to health, safety and protection of the environment
("Environmental Laws"). As such, the nature of the Company's operations as well
as previous operations by others at real property owned, leased or used by the
Company, expose the Company to the risk of claims under Environmental Laws, and
there can be no assurance that material costs or liabilities will not be
incurred in connection with such claims. Based on its experience to date, the
Company does not expect such claims or the costs of compliance with the scope or
enforcement of Environmental Laws to have a material impact on its earnings or
competitive position. The Company believes that it is in substantial compliance
with applicable Environmental Laws. No assurance can be given, however, that the
discovery of presently unknown environmental conditions, changes in the scope or
enforcement of Environmental Laws or their interpretation, or other
unanticipated events will not give rise to expenditures or liabilities that may
have a material adverse effect on the Company's business, financial condition or
results of operations. The Company, through its acquisition of Monsey Bakor, has
been named as a potentially responsible party in litigation concerning
contamination at a former waste-oil recycling facility used by it in
Douglassville, Pennsylvania. The Company, also through its acquisition of Monsey
Bakor, is also a party to a consent decree issued by the federal Environmental
Protection Agency relating to remediation of contamination at its corporate
headquarters. It is sharing remediation costs with a former owner of the
facility that is also a party to the consent decree. Based on currently
available information, the Company believes that neither this litigation nor
this remediation will have a material adverse effect on the Company's business,
financial condition or results of operations.
 
GOVERNMENTAL REGULATION AND PERMITS
 
    The Company is subject to regulation under various federal, state and local
laws, including laws regulating its manufacturing operations and laws relating
to employee health and safety. Permits are required for operation of the
Company's business, and such permits are subject to renewal, modification and,
in certain circumstances, revocation by governmental authorities. The loss of
certain of such permits could have a material adverse effect on the Company's
business, financial condition or results of operations. The Company expects to
incur ongoing capital and operating costs and administrative expenses to
maintain compliance with its permits and with applicable laws and regulations.
The Company cannot predict the legislation or regulations that may be enacted in
the future or how existing or future laws or regulations will be administered or
interpreted. Compliance with new laws or regulations, as well as more vigorous
enforcement policies of the regulatory agencies or stricter interpretation of
existing laws, may require additional expenditures by the Company, some or all
of which may be material.

    The Company also owns or leases smaller sales and administration facilities
in Costa Mesa, California, Irvington, New Jersey and Mississauga, Ontario. In
addition, the Company owns a small facility in Troy, New York that it leases to
a third party. The Company believes that its facilities are in good operating
condition and are adequate to meet anticipated future requirements.
 
ITEM 3. LEGAL PROCEEDINGS
 
    In the ordinary course of business, the Company is periodically named as a
defendant in a variety of product liability lawsuits including "slip and fall"
claims relating to pavement sealants and claims for alleged product failure. The
Company does not believe these cases will have a material adverse effect on the
Company's business, financial condition or results of operations.
 
    The Company, by way of its acquisition of Monsey Bakor, has been identified
as a participating responsible party by the EPA under the Comprehensive
Environmental Response, Compensation and Liability Act of 1980, as amended, in
litigation in the Federal District Court for the Eastern District of
Pennsylvania. The Company's involvement with the property, a former waste oil
recycling facility in Douglassville, Pennsylvania, was limited to the temporary
storage and treatment of certain solvents on the site. A proposed consent decree
covering the EPA's alleged response costs has been negotiated with the EPA which
would fix the responsibility for the Company and approximately 150 other
potentially responsible parties who were determined to be responsible for a
minor portion of such costs. The Company's portion of this settlement would be
approximately $372,000.
 
    As of December 31, 1998, The Company was a party to approximately 55 state
court cases alleging certain asbestos-related injuries. There were seven new
cases filed in 1998, two in 1997 and four filed each in 1996 and 1995. The
Company believes that its use of chrysotile asbestos fibers, which are
encapsulated by asphalt in the manufacturing process, is in accordance with
applicable laws. Although the Company has not paid any amounts in judgment or
settlement of any asbestos-related claim to date, there can be no assurance that
any such claim will not in the future result in a material adverse judgment
against, or settlement by, the Company. The costs of these suits are currently
funded by a joint-defense arrangement among the Company's insurance carriers and
the Company believes that such insurance coverage is adequate. However, Henry
Company is not covered by insurance for asbestos-related claims for injuries
that are alleged to have arisen after 1985.
 
    The Company does not believe, based in part on the advice of outside
counsel, that the outcome of these suits and legal proceedings will have a
material adverse effect on the Company's financial condition, results of
operations, or cash flows.
 
                                       11
<PAGE>
    ENVIRONMENTAL MATTERS
 
    The Company is subject to extensive and changing environmental laws and
regulations with which it believes it is in substantial compliance. However,
there can be no assurance that the discovery of presently unknown environmental
conditions or changes in the scope, interpretation or enforcement of
environmental laws and regulations will not have a material adverse effect on
the Company's business, financial condition or results of operations.
 
    The Company's Kimberton facility was formerly occupied by a pharmaceutical
manufacturer whose operations resulted in groundwater contamination identified
on the site and surrounding area. The contaminant of concern was
trichloroethylene which required various remedial activities, including the
provision of alternate water supplies to users in the surrounding area and a
groundwater treatment program. Remedial work is being completed under a consent
decree the EPA negotiated in 1990 with the pharmaceutical manufacturer and the
Company and a confidential cost sharing agreement between these two companies.
The Company's costs under the consent decree in 1996, 1997 and 1998 were
approximately $63,000, $67,000 and $70,000, respectively, and are not expected
to be significantly different during 1999 and 2000. The Company has a liability
recorded for the entire expected costs to it of the remedial work over the
remaining term of the consent decree and cost-sharing agreement. Costs paid
under the consent decree and cost-sharing agreement of $70,000 in 1998 reduced
the liability to $3.4 million at December 31, 1998.
 
    The Company is currently upgrading, replacing or closing underground storage
tanks that it owns or operates to meet certain corrosion protection and
overfill/spill containment standards. The Company estimates that the capital
expenditures required to comply with various regulatory programs in 1999 will
not have a material adverse effect on the Company's earnings, cash flows or
competitive position. Such estimates, however, are based on factors and
assumptions that are subject to change, including potential modifications of
regulatory requirements, detection of unanticipated environmental conditions or
other currently unexpected circumstances.
 
ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS
 
    No matters were submitted to a vote of the Company's stockholders during the
fourth quarter of the fiscal year covered by this report.

ITEM 5. MARKET FOR THE REGISTRANT'S COMMON EQUITY AND RELATED SHAREHOLDER
        MATTERS
 
    There is no established public trading market for the Company's common
equity.
 
    As of December 31, 1998, there were seven (7) beneficial holders of the
Company's Common Stock and one beneficial holder of the Company's Class A Common
Stock.
 
    At the present time, the Company intends to retain all earnings for use in
the operation and development of its business and does not expect to declare or
pay any cash dividends in the foreseeable future. Any determination in the
future to pay dividends will depend on the Company's earnings, financial
condition, capital requirements, level of indebtedness and other factors deemed
relevant by the Company's Board of Directors, including any contractual or
statutory restrictions on the Company's ability to pay dividends.
 
ITEM 6. SELECTED FINANCIAL DATA
 
    The following selected consolidated financial data should be read in
conjunction with Henry Company's consolidated financial statements and related
notes thereto and "Management's Discussion and Analysis of Financial Condition
and Results of Operations" included elsewhere in this document. The consolidated
statement of operations data for each of the years in the three-year period
ended December 31, 1998, and the consolidated balance sheet data at December 31,
1997 and 1998, are derived from the consolidated financial statements of Henry
Company which have been audited by PricewaterhouseCoopers LLP, independent
accountants, and are included elsewhere in this document. The consolidated
statement of operations data for the years ended December 31, 1994 and 1995,
respectively, and the consolidated balance sheet data at December 31, 1994,
1995, and 1996 are derived from audited financial statements of Henry Company
not included in the document. Historical results are not necessarily indicative
of the results to be expected in the future.

(1) For periods prior to April 22, 1998, the Company's financial statements were
    prepared on a combined basis with Warner Development Company of Texas
    ("Warner Development") as both entities were under common control with
    identical shareholder ownership interests. On April 21, 1998, Warner
    Development was merged into Henry Company and the outstanding shares of
    Warner Development capital stock were cancelled.
 
(2) Prior to April 1998, Henry Company was operated as a subchapter "S"
    Corporation under the Code. As a result, Henry Company did not incur Federal
    and state income taxes (except with respect to certain states) and,
    accordingly, the provision for income taxes only includes the applicable
    state income tax. Federal and state income taxes (except with respect to
    certain states) on the income of Henry Company have been incurred and paid
    directly by the shareholders of Henry Company. It has been the policy of
    Henry Company to make periodic distributions to the shareholders in respect
    of such tax liabilities. During the year ended December 31, 1998, Henry
    Company paid distributions of $1.2 million for the shareholders' 1997 tax
    liabilities. On April 22, 1998, the Company converted to a "C" corporation
    under the Code and will subsequently pay all future tax obligations of the
    Company to the appropriate taxing authorities.
 
(3) As described in Note (2) above, Henry Company was operated as a Subchapter
    "S" Corporation for the historical years presented through 1997. The pro
    forma provision (benefit) for income taxes and pro forma net income (loss)
    reflect the results as if Henry Company were operated as a "C" Corporation
    for the historical periods presented.

(4) EBITDA, as defined in the indenture relating to the Company's outstanding
    10% Senior Notes, represents net earning before taking into consideration
    taxes on earnings, interest expense, depreciation and amortization, and
    non-recurring, non-cash charges, less any cash expended that funds a non-
    recurring, non-cash charge. While EBITDA should not be construed as a
    substitute for operating earnings, net earnings, or cash flows from
    operating activities in analyzing operating performance, financial position
    or cash flows, EBITDA has been included because it is commonly used by
    certain investors and analysts to analyze and compare companies on the basis
    of operating performance, leverage and liquidity. This data is relevant to
    an understanding of the economics of the Company's business as it indicates
    cash flow available from operations (and/or trends in cash flow available
    from operations) to service debt and satisfy certain fixed obligations. A
    reconciliation of net income (loss) to EBITDA for the respective years and
    related interim periods is as follows:

(5) For purposes of this ratio, "earnings" consist of earnings before income
    taxes and fixed charges and "fixed charges" consist of interest expense and
    the portion of rents representative of an interest factor. The ratio of
    earnings to fixed charges is computed by adding earnings before income taxes
    and fixed charges and dividing by fixed charges.
 
(6) The earnings were insufficient to cover fixed charges for these periods. The
    amount of the deficiencies were $319 and $504 in 1994 and 1995,
    respectively.
 
(7) On April 22, 1998, the Company acquired Monsey Bakor and its subsidiaries.
    The acquisition was accounted for using the purchase method of accounting
    and as such, the results of operations of Monsey Bakor since the acquisition
    date have been included in the consolidated financial statements of the
    Company.

BUSINESS ACQUISITION, NOTE OFFERING, AND CHANGE IN TAX STATUS
 
    On April 22, 1998, the Company completed the acquisition of Monsey Bakor and
its subsidiaries (the "Acquisition") which are engaged in the distribution and
manufacture of roof coatings, adhesives and membranes, and waterproofing and air
barrier systems for residential and commercial applications. The cash purchase
price was $42.8 million with an additional $3.2 million paid at closing to
certain selling shareholders of Monsey Bakor for noncompetition agreements. A
selling shareholder also purchased
 
                                       16
<PAGE>
22,500 of redeemable convertible preferred stock of the Company for $0.6 million
cash. The Acquisition has been accounted for using the purchase method of
accounting.
 
    Concurrent with the Acquisition, the Company conducted a senior note
offering (the "Offering") in the aggregate principal amount of $85.0 million.
The proceeds of the Offering were used to acquire Monsey Bakor, retire a
substantial portion of Monsey Bakor's existing bank debt, and retire the
Company's existing bank debt and subordinated shareholder debt.
 
    Concurrent with the Acquisition and Offering, the Company's bank credit line
was replaced with a $35.0 million credit facility, $25.0 million of which is
available in accordance with a borrowing base and is to be used for working
capital, and $10.0 million of which may be used for capital expenditures.
 
    Concurrent with the Acquisition and the Offering, the Company converted its
tax status from an S Corporation under Section 1361 of the Code to C Corporation
status. Subsequent to this conversion the Company will be required to pay
federal and state corporate income taxes on its taxable income.
 
    Upon conversion to C status, the Company recognized a net deferred tax asset
of $0.9 million in accordance with the liability method of accounting for income
taxes. Under this 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.

</TABLE>
 
YEAR ENDED DECEMBER 31, 1998 COMPARED TO YEAR ENDED DECEMBER 31, 1997
 
    NET SALES.  The Company's net sales increased to $150.1 million for the year
ended December 31, 1998, an increase of $82.7 million, or 122.7%, from $67.4
million for the year ended December 31, 1997. The acquisition of Monsey Bakor
(the "Acquisition") represented $84.4 million of the increase and was partially
offset by a decrease of $1.7 million due primarily to the lack of rainfall in
excess of annual averages, which resulted in decreased net sales in both the
professional and retail roofing business as the need to repair leaking roofs was
not as pronounced.
 
                                       17
<PAGE>
    GROSS PROFIT.  The Company's gross profit increased to $45.0 million for the
year ended December 31, 1998, an increase of $24.0 million, or 114.3%, from
$21.0 million for the year ended December 31, 1997. The acquisition of Monsey
Bakor represented $22.4 million of the increase. The remaining increase of $1.6
million was primarily due to a decrease in certain raw material prices and an
improved sales mix of higher margin products.
 
    SELLING, GENERAL AND ADMINISTRATIVE.  Selling, general and administrative
expense as a percentage of net sales decreased to 23.3% for the year ended
December 31, 1998 from 26.0% for the year ended December 31, 1997. The decrease
was primarily due to the Company's ability to support increased levels of
revenues from the acquisition of Monsey Bakor without proportionately increasing
administrative costs. Selling, general and administrative expenses increased to
$35.0 million for the year ended December 31, 1998, an increase of $17.5
million, or 100.0%, from $17.5 million for the year ended December 31 1997. The
acquisition of Monsey Bakor represented $16.4 million of the increase. The
remaining increase of $1.1 million was primarily due to incremental selling,
general and administrative expenses associated with the Company's continued
expansion in both the retail roofing and the roofing systems business.
 
    AMORTIZATION OF INTANGIBLES.  Amortization of intangibles increased to $2.1
million for the year ended December 31, 1998, an increase of $2.0 million or
2000%, from $0.1 million for the year ended December 31, 1997. The increase was
primarily due to the amortization of intangible assets created as a result of
the Acquisition.
 
    OPERATING INCOME.  Operating income increased to $7.9 million for the year
ended December 31, 1998, an increase of $4.5 million, or 132.4%, from $3.4
million for the year ended December 31, 1997. Operating income as a percentage
of net sales increased to 5.3% for the year ended December 31, 1998, from 5.0%
for the year ended December 31, 1997. The acquisition of Monsey Bakor
represented $5.7 million, or 126.7% of the increase in operating income. The
Monsey Bakor increase was partially offset by the amortization of intangible
assets created as a result of the Acquisition and increased selling, general and
administrative expenses mitigated by the improvements in the gross profit margin
as noted above.
 
    INTEREST EXPENSE.  Interest expense increased to $6.6 million for the year
ended December 31, 1998, an increase of $5.1 million, or 340.0%, from $1.5
million for the year ended December 31, 1997. The increase was attributable to
interest expense incurred on the Senior Notes used to finance the Acquisition.
 
    PROVISION FOR INCOME TAXES.  The provision for income taxes increased to
$0.5 million for the year ended December 31, 1998 primarily due to the
Acquisition and the conversion of the Company from an "S" Corporation to a "C"
Corporation, which resulted in the Company becoming a fully taxable entity in
the year ended December 31, 1998. These factors were partially offset by a $0.9
million deferred tax benefit recognized upon conversion.
 
    NET INCOME.  Net income was $1.1 million for the year ended December 31
1998, a decrease of $1.1 million, or 50.0% from $2.2 million for the year ended
December 31, 1997. The Acquisition represented an increase of $3.9 million,
which was offset by increased amortization expense, increased interest expense
and other factors noted above.
 
YEAR ENDED DECEMBER 31, 1997 COMPARED TO DECEMBER 31, 1996
 
    NET SALES.  The Company's net sales increased to $67.4 million in 1997, an
increase of $8.2 million, or 13.9%, from $59.2 million for the prior year. This
increase was primarily due to forecasted rainfall in excess of annual averages,
which increased sales in both the professional and retail roofing business as
property owners in California and Arizona repaired roofs during the third and
fourth quarters of 1997 in anticipation of significant rainfall. The increase in
revenues was also attributable to Henry Company's increased market penetration
into contiguous regions.
 
                                       18
<PAGE>
    GROSS PROFIT.  Gross profit increased to $21.0 million in 1997, an increase
of $2.7 million, or 14.8%, from $18.3 million for 1996. This increase was
primarily due to the increased revenues, but also reflects an increase in Henry
Company's gross profit margin increased to 31.2% from 30.9% in the prior year.
This increase in gross profit margin was primarily attributable to a higher
proportion of revenues from the sales of roof patching cement, which
historically has had higher gross profit margins than other roof coatings lines
and polyurethane foam applications. The increase in gross profit margin was
partially offset by decreased revenues from certain higher-margin segments of
the sealants business.
 
    SELLING, GENERAL AND ADMINISTRATIVE.  Selling, general and administrative
expense as a percentage of revenue decreased to 26.0% in 1997 from 28.7% in
1996. The decrease was primarily due to Henry Company's ability to service
increased revenues without proportionately increasing administrative costs.
Selling, general and administrative expenses increased to $17.5 million in 1997,
an increase of $0.6 million, or 3.6%, from $16.9 million in 1996. The increase
was primarily due to incremental selling, general and administrative expenses
associated with Henry Company's continued expansion into the roofing systems
business as well as increased overhead related to the hiring of additional
employees in connection with the overall growth of Henry Company.
 
    AMORTIZATION OF INTANGIBLES.  Amortization of intangibles decreased slightly
to $0.1 million in 1997 as compared to $0.2 million in 1996. This decrease
represents amortization expense related to an acquisition completed in February
of 1994.
 
    OPERATING INCOME.  Operating income increased to $3.4 million in 1997, an
increase of $2.2 million, or 183.3%, from $1.2 million in 1996. Operating income
as a percentage of revenue increased to 5.0% in 1997 from 2.0% in the prior
year, primarily due to higher gross profit margins and lower operating expenses
as a percentage of revenues.
 
    INTEREST EXPENSE.  Interest expense remained flat from 1996 to 1997 and
relates principally to interest expense on Henry Company's debt utilized to fund
the working capital needs of the Company.
 
    NET INCOME.  Net income was $2.2 million in 1997, an increase of $2.1
million, from $0.1 million in 1996 due primarily from increased revenues. Net
income as a percentage of revenues increased to 3.2% in 1997, from a nominal
return in 1996, primarily due to an increase in net sales in 1997.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    The Company's historical requirements for capital have been primarily for
working capital, capital expenditures and acquisitions. The Company's primary
sources of capital to finance such needs have been cash flow from operations and
borrowings under bank credit facilities. Concurrently with the consummation of
the Offering and the Acquisition on April 22, 1998, the Company entered into a
new bank credit facility (the "Credit Facility") which provides for $25.0
million which is available in accordance with a borrowing base and is to be used
for working capital, and $10.0 million which may be used for capital
expenditures. As of December 31, 1998, there were no amounts outstanding under
the revolving line of credit and the capital expenditure facility. The Company
also maintains a credit line with a Canadian bank. Balances outstanding under
this line were $1.7 million at December 31, 1998.
 
CASH FLOWS FOR THE YEAR ENDED DECEMBER 31, 1998 COMPARED TO THE YEAR ENDED
  DECEMBER 31, 1997
 
    The Company's cash flows from operations were $10.0 million and $4.8 million
for the years ended December 31, 1998 and 1997 respectively. The increase from
December 31, 1997 to December 31, 1998 of $5.2 million was primarily
attributable to a reduction in trade receivables and inventories. This reduction
is largely a result of the decline in trade receivables and inventories of
Monsey Bakor from the date of acquisition to December 31, 1998. Net cash
provided by (used in) financing activities during the year ended December 31,
1998 and the year ended December 31, 1997 was $50.4 million and $(4.0) million
respectively. The increase of $54.4 million from the year ended December 31,
1997 to the year ended
 
                                       19
<PAGE>
December 31, 1998 was primarily due to the issuance of $85.0 million of senior
notes, reduced by debt payments of $33.4 million. Net cash used for business
acquisitions for the year ended December 31, 1998 and for the year ended
December 31, 1997 were $45.1 million and $0.1 million, respectively. For the
year ended December 31, 1998 and the year ended December 31, 1997 additions for
capital expenditures were $3.0 million and $0.8 million, respectively. Scheduled
principal payments on debt were $16.7 million and $1.3 million for the year
ended December 31, 1998 and the year ended December 31, 1997, respectively.
 
    The Company believes that the net proceeds from the Offerings, together with
available cash and cash equivalents, cash generated from operations and
available borrowings under the Credit Facility, will be sufficient to finance
working capital, capital expenditures, acquisitions, and scheduled principal and
interest payments for the next twelve months. There can be no assurance,
however, that such resources will be sufficient to meet the Company's
anticipated working capital, capital expenditure and acquisition financing
requirements or that the Company will not require additional financing within
this time frame.
 
RECENT ACCOUNTING PRONOUNCEMENTS
 
    In March 1998, the American Institute of Certified Public Accountants
("AICPA") issued Statement of Position ("SOP") No. 98-1, "Software for Internal
Use", which provides guidance on accounting for the cost of computer software
developed or obtained for internal use. SOP No. 98-1 is effective for financial
statements for fiscal years beginning after December 15, 1998. The Company does
not anticipate that the adoption of SOP No. 98-1 will have a material impact on
the Company's financial position, results of operations, or cash flows.
 
    In April 1998, the AICPA issued SOP No. 98-5 "Reporting on the Costs of
Start-up Activities". SOP No. 98-5, which is effective for fiscal years
beginning after December 15, 1998, provides guidance on the financial reporting
of start-up costs and organization costs. It requires costs of start-up
activities and organization costs to be expensed as incurred. As the Company has
expensed these costs historically, the adoption of this standard will not have a
significant impact on the Company's financial position, results of operations,
or cash flows.
 
    In June 1998, the Financial Accounting Standard Board ("FASB") issued
Statement of Financial
Accounting Standards No. 133, "Accounting for Derivatives and Hedging
Activities", which establishes accounting and reporting standards for derivative
instruments, including certain derivative instruments embedded in other
contracts (collectively referred to as derivatives) and for hedging activities.
SFAS No. 133 is effective for all fiscal quarters of fiscal years beginning
after June 15, 1999. The Company does not expect the adoption of this statement
to have a significant impact on the Company's financial position, results of
operations, or cash flows.
 
YEAR 2000 MODIFICATIONS
 
    The Company is not highly dependent on its internal computer systems, and
does not generally interact electronically with its customers or suppliers. The
Company has been and is currently assessing its computer systems and
embedded-technology equipment in order to evaluate what, if any, corrections or
modifications may be necessary to respond to potential Year 2000 computer
issues. The Company currently expects to complete any necessary corrections or
modifications by April 30, 1999. The historical costs of this assessment and
correction have been less than $10,000 and future assessment and correction
(including replacement) costs are currently estimated to be less than $50,000.
The company relies upon computer systems primarily to invoice its customers,
some of whom are billed on an Electronic Data Interchange ("EDI") system. The
most reasonably likely risk to the Company for a Year 2000 failure is believed
to involve an interruption of this electronic invoicing system. The Company is
prepared to invoice its customers manually in the event of such an interruption.

QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK
 
    Market risk generally represents the risk that losses may occur in the value
of financial instruments as a result of movements in interest rates, foreign
currency exchange rates and commodity prices. As part of its overall risk
management strategies, the Company monitors and manages these risks by reviewing
key trends and indicators on a continuous basis.
 
    Interest Rate Risk--From time to time the Company temporarily invests its
excess cash in interest bearing temporary investments of high quality issuers or
with major financial institutions. Due to the short-term maturity of the
investments are outstanding and their general liquidity, these instruments are
classified as cash equivalents in the consolidated balance sheet and do not
represent a material interest rate risk to the Company. The Company's primary
market risk exposure for changes in interest rates relates to the Company's debt
obligations. The Company manages its exposure to changing interest rates
principally through the use of a combination of fixed and floating rate debt.
The majority of the Company's long-term debt is comprised of $85.0 million of
Series B Senior Notes which represent fixed rate borrowings. The fair value of
the Senior Notes at December 31, 1998 was approximately $101.0 million.
 
    The Company believes that near term changes in interest rates would not have
a significant impact on the Company's financial position as the Company has a
limited amount of interest rate risk sensitive financial instruments at December
31, 1998.
 
    Foreign Exchange Rate Risk--The Company conducts business principally in
North America and in U.S. and Canadian currencies. The Company's U.S. operations
denominates all sales transactions in U.S. dollars. The Company's Canadian
subsidiaries are paid in Canadian dollars for sales made in Canada. Excess
Canadian funds generally have been invested in the Canadian operation rather
than being remitted to the U.S. parent.
 
    At December 31, 1998, the Company has no foreign currency exchange contracts
or hedging instruments.
 
    Commodity Price Risk--The Company uses certain raw materials in its
manufacturing process that fluctuate with certain commodity prices. These raw
materials include asphalt, aluminum paste, rubber and certain dissoynates. The
Company continuously monitors key trends in the commodity prices impacting raw
materials. At December 31, 1998, the Company has no commodity risk hedges or
derivative instruments.

EXECUTIVE DEFERRAL PLAN
 
    Henry Company has adopted an Executive Deferral Plan (the "Plan") to allow
certain management personnel and highly compensated employees to defer a portion
of their annual salary and bonus to be paid at a future date chosen by them or
upon their retirement, death, disability or termination of employment.
Participants in the Plan are selected by an administrative committee (the "Plan
Committee") appointed by the Board of Directors which establishes eligibility
qualifications and manages and administers the Plan. To participate in the Plan
for any year, a participant must make an irrevocable election to defer at least
$2,000 to a maximum of 100% of his or her base salary and bonus for such year
prior to the beginning of the year for which the salary and bonus relate. For
each Plan year Henry Company may contribute to each participant's account at the
Plan Committee's discretion. Deferred amounts are credited with interest at the
September "Moody's Seasoned Corporate Bond" rate that is published prior to the
end of the Plan year preceding the Plan year for which the rate is used.
Participants are at all times fully vested in their deferred compensation
accounts except in the event of a termination of their employment, in which case
participants are vested to only a percentage of any Company contributions that
have been made, calculated according to the executive's number of years of
employment. At the time of deferral, participants may elect to receive future
short-term payouts with respect to each year's deferral, payable in a lump sum
not prior to the sixth Plan year following such deferral. Amounts payable to a
participant pursuant to the Plan are unfunded amounts to be paid from the
general assets of the Company
 
                                       26
<PAGE>
and are at all times subject to the risk of the Company's business. The Company
funds the Plan with whole life insurance policies.
 
PROFIT SHARING/401(k) PLAN
 
    Henry Company's Profit Sharing/401(k) Plan, as amended and restated as of
January 1, 1995 (the "401(k) Plan") is a qualified profit sharing plan with a
401(k) feature covering salaried and hourly employees of Henry Company and its
affiliates, other than union employees, who have completed one year of service
and attained the age of 21. Participants in the 401(k) Plan may contribute up to
15% of their annual compensation to the 401(k) Plan through salary deferral up
to a maximum of $10,000. In addition, Henry Company may make annual
discretionary matching contributions not to exceed 10% of a participant's annual
compensation. Participating employees are 100% vested in participant
contributions and become vested to a certain percentage of any Henry Company
discretionary matching contributions according to the employee's years of
service with Henry Company or its affiliates.
 
EMPLOYMENT AGREEMENTS AND COMPENSATION ARRANGEMENTS
 
    Henry Company has entered into employment agreements with Mr. Gordinier, Mr.
Doose, Mr. Enright, Mr. Mooney and Mr. Karasiuk, and into incentive compensation
agreements with Mr. Enright and Mr. Wahba.
 
    Mr. Gordinier's employment agreement entitles him to a base salary and a
bonus, subject to annual review by the Executive Committee of the Board of
Directors, and to certain other benefits, including reimbursement of certain
club memberships. In 1998, Mr. Gordiner's base salary was $285,875 and his bonus
was $100,000. In addition, Mr. Gordinier received a bonus payment of $100,000 at
the closing of the acquisition of Monsey Bakor. Mr. Gordinier is also entitled
to a bonus if a distribution of money or assets is made to the shareholders of
the Company. If a distribution is made because of a sale of the Company, Mr.
Gordinier would receive 10% of the sale amount in excess of $5,895,595, reduced
by $200,000 and the outstanding balance of any outstanding loans to Mr.
Gordinier (the "Reduction Amount"). In connection with Mr. Gordiner's
employment, Henry Company has loaned him a total of $175,000 which does not bear
interest. As of December 31, 1998, the aggregate amount outstanding under these
loans was $175,000. If Mr.Gordinier voluntarily terminates his employment or if
the Company terminates his employment for any reason other than "for cause" (as
defined in the employment agreement), Mr. Gordinier is entitled to a one-year
severance payment equal to his then salary and guaranteed bonus and a
termination award (the "Termination Award"). The Termination Award is equal to
10% of the amount by which the fair market value of the Company exceeds
$5,895,595, such fair market value to be determined by appraisal, subject to
reduction by the Reduction Amount. The Company maintains a life insurance policy
on the life of Mr. Gordinier in the amount of $2,000,000 to assist in funding
the Termination Award. The Termination Award is payable in four equal annual
installments, with the unpaid balance bearing interest at the Bank of America
prime rate existing on the due date of the first installment. Mr. Gordinier's
employment agreement automatically renews annually, unless terminated earlier by
either party.
 
    Mr. Doose's employment agreement provides for a base salary, subject to
annual cost-of-living and discretionary increases. For 1998, Mr. Doose's base
salary was $237,450. Mr. Doose also receives annual bonuses based on the net
operating profits of, and on the return on capital employed at, RTC. If Mr.
Doose is terminated without cause, he is entitled to base compensation plus the
bonus calculated on net operating profits for the remaining term of the
agreement. The agreement contains a covenant restricting Mr. Doose from
competing with Henry Company for two years after the termination of employment.
Mr. Doose's employment agreement terminates January 1, 2004.
 
    Pursuant to his employment agreement, Mr. Enright receives an annual base
salary, currently $158,500, subject to annual discretionary increases, and an
annual incentive bonus based upon certain agreed-upon objectives, which totaled
$7,007 in 1998. During the term of Mr. Enright's employment, and
 
                                       27
<PAGE>
for twelve months following termination, Mr. Enright has agreed not to directly
or indirectly compete with or engage in a business competitive with the Company.
Mr. Enright's employment agreement is automatically extended for additional
one-year terms each July 1, unless terminated sooner.
 
    Mr. Enright's incentive compensation agreement provides for deferred
compensation based upon an increase in the net book value of the Henry Sealants
Division. This amount is payable to Mr. Enright upon his termination or the
Division's cessation of operations (the "Termination Date"), although the
Company may accelerate the benefit in the event of Mr. Enright's death or
disability. Beginning January 1, 1998, Mr. Enright received annually 25% of the
deferred benefit amount that would be payable if the Termination Date had
occurred as of the end of the previous fiscal year. In addition, if Henry
Company sells all or substantially all of the assets of the Henry Sealants
Division, Mr. Enright is entitled to an amount equal to the greater of the
deferred benefit amount as of the month preceding such sale or an amount based
on the excess of the amount of sales proceeds over an initial defined book value
of the Division.
 
    Henry Company has entered into an incentive compensation agreement with Mr.
Wahba providing for additional compensation to Mr. Wahba upon the termination of
his employment, Henry Company's liquidation or cessation of business, or a
change of control of Henry Company. Such compensation is based upon the
cumulative operating profit for certain Henry Company divisions from a starting
date in 1988 or 1990. A portion of the deferred benefit amount may be paid to
Mr. Wahba following each fiscal year. In addition, Mr. Wahba is entitled to
receive a payment based on the excess of the amount of proceeds received from
the sale of a Henry Company division over an initial defined book value for that
division.
 
    Mr. Mooney is a Vice Chairman of the Board of the Company with an annual
base salary of $350,000, subject to annual review. The term of Mr. Mooney's
employment agreement is for two years from the closing of the Acquisition. With
respect to the capital stock of the Company that was purchased by Mr. Mooney in
connection with the Acquisition, Mr. Mooney has the right to require the Company
to repurchase one-sixth of such capital stock each year over a five-year period
beginning January 1, 2004 (except that the last one-sixth would be repurchased
July 1, 2008) for an aggregate purchase price of $3.0 million. Such capital
stock would also be repurchased upon Mr. Mooney's death, in which event the
purchase would be funded by the proceeds from the key person life insurance
policies the Company holds on Mr. Mooney's life.
 
    Mr. Karasiuk is employed as the President of the Company's Monsey Bakor
division with an annual base salary of Canadian $250,000, subject to annual
review. Mr. Karasiuk is also entitled to an annual bonus of up to 50% of his
base salary in the discretion of the Company's Board of Directors. The term of
Mr. Karasiuk's employment agreement is for three years from the closing of the
Acquisition.
 
INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    The Company's Articles of Incorporation authorize the indemnification of
Company officers and directors to the fullest extent permissible under
California law. Subject to the Articles of Incorporation and California law, the
Bylaws provide that Henry Company shall indemnify each of its directors and
officers against expenses, judgments, fines, settlements and other amounts
actually and reasonably incurred in connection with any proceeding arising by
reason of the fact that any person is or was a Company director or officer. The
Company also purchased a director's and officer's liability insurance policy
following the Acquisition.

of $2,000,000 on the life of Richard B. Gordinier, under which Henry Company is
the sole beneficiary. The Company also maintains whole life insurance policies

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
    The Company leases its Huntington Park headquarters and certain operating
equipment from a family trust and living trust for which Warner W. Henry is the
trustee pursuant to three separate real property leases and one equipment lease.
These leases expire in 2002, 2006 and 2016. The total rent paid in 1997 and 1998
for the Huntington Park leases was approximately $424,904 each year. The Company
leases additional property at its Huntington Park headquarters from Alamo
Development Company. Frederick H. Muhs, a director of the Company, is a
shareholder of Alamo Development Company along with certain other members of his
family. The Company currently pays rent of $5,330 per month pursuant to this
lease which is subject to annual adjustments to reflect changes in the Bank of
America prime rate. The lease expires February 28, 2002 and provides for the
Company's option to purchase the property upon six months written notice. The
Company also leases certain warehouse facilities in Irvington, New Jersey, from
Sea Jay, Inc. The shareholders of Sea Jay, Inc. are Joseph T. Mooney, Jr. and
certain of his family members. The Company currently pays rent of $2,333 per
month pursuant to this lease which expires December 31, 1999. The Company has
the option to extend the lease for five additional consecutive one year terms at
increasing annual rental amounts. The Company believes that the rent paid under
the above leases represent substantially fair market value and that the other
terms and conditions of the leases are commercially reasonable.
 
    Henry Company has made loans to Richard B. Gordinier for personal reasons
pursuant to various loan agreements and promissory notes originated at various
times since 1988 for one year terms that were subsequently extended for
successive one year terms. The loans currently bear interest at Bank of
America's prime rate, currently 7.75%, and may be prepaid without penalty. As of
December 31, 1998, an aggregate of $426,672 was outstanding on these loans. In
addition, Mr. Gordinier has received $175,000 of non-interest bearing loans in
connection with his employment. See "Management--Employment Agreements and
Compensation Arrangements."
 
    Henry Company performs certain administrative services for an affiliate,
Henry II Company, a California corporation, pursuant to an administrative
services agreement that provides for payments from Henry II Company to Henry
Company. These payments totaled $1.1 million in 1998. Henry II Company's
shareholders are Warner W. Henry, Carol Henry, and certain trusts for the
benefit of their children.
 
    At December 31, 1997, Henry Company received a note from Henry II Company
for $1.9 million representing the purchase price for its interest in certain
real property. Such real property related solely to the business of Henry II
Company and had a net book value of $1.9 million. The note bears interest at the
prime rate, and is repayable in a lump sum at any time up to December 31, 2002.
The balance of such note was $1.9 million at December 31, 1998. In addition, at
December 31, 1998, Henry II Company owed $2.4 million to Henry Company,
representing past advances made on behalf of Henry II Company. The note
evidencing this debt does not bear interest and is payable upon demand.
 
    Henry Company receives business and financial consulting services from The
Muhs Company, Inc., of which Frederick H. Muhs, a director of the Company, is
the President and controlling shareholder. Henry Company paid $36,000 for these
services in 1997 and $36,000 in 1998. See "Executive Compensation."

directors and officers of the Company. See "Employment Agreements and

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors,
  Bond Holders and Shareholders
  of Henry Company
 
In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of operations, changes in shareholders' equity and of
cash flows present fairly, in all material respects, the financial position of
Henry Company and subsidiaries (the "Company") at December 31, 1997 and 1998,
and the results of their operations and their cash flows for each of the three
years in the period ended December 31, 1998, in conformity with generally
accepted accounting principles. These financial statements are the
responsibility of the Company's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with generally accepted
auditing standards which 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, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

                                 HENRY COMPANY
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
BASIS OF PRESENTATION
 
    The consolidated financial statements of Henry Company (the "Company")
include the accounts of the Company and its subsidiaries. All significant
intercompany accounts and transactions have been eliminated.
 
    For periods prior to April 21, 1998, the Company's financial statements were
prepared on a combined basis with Warner Development Company of Texas ("Warner
Development") as both entities were under common control with identical
shareholder ownership interests. On April 21, 1998, Warner Development was
merged into Henry Company and the outstanding shares of Warner Development
capital stock were cancelled.
 
    As more fully described in Note 2, the consolidated financial statements for
the year ended December 31, 1998 include the financial results and accounts of
Monsey Bakor and its subsidiaries which were acquired (the "Acquisition") by the
Company on April 22, 1998. The Acquisition was accounted for using the purchase
method of accounting and, accordingly, the results of operations of Monsey Bakor
since the acquisition date have been included in the consolidated financial
statements of the Company.
 
    The Company develops, manufactures and markets materials for the
construction industry focusing primarily on roofing, sealing and paving
applications. The Company's products include: roof/driveway coatings and paving
products, industrial emulsions, air barriers, specialty products, polyurethane
foam for residential and commercial uses, and sealants for the construction and
marine industries.
 
REVENUE RECOGNITION
 
    Revenues are recognized when products are shipped. The Company has
established programs which, under specified conditions, allow customers to
return products. The Company establishes liabilities for estimated returns and
allowances at the time of shipment. In addition, accruals for customer discounts
and returns are recorded when revenues are recognized.
 
CASH AND CASH EQUIVALENTS
 
    The Company considers all highly liquid investments purchased with an
original maturity of three months or less to be cash equivalents.
 
    Under the Company's cash management system, checks issued but not presented
to banks frequently result in overdraft balances for accounting purposes and are
included in "Accounts Payable" in the accompanying balance sheet. At December
31, 1997, these overdraft balances amounted to $1,488,003. There were no
overdraft balances at December 31, 1998.
 
INVENTORIES
 
    Inventories are valued at the lower of cost (first-in, first-out) or market.
Cost is determined using standard cost which approximates actual costs on a
first-in, first-out method.
 
PROPERTY AND EQUIPMENT
 
    Property and equipment are stated at cost. Leasehold improvements are
amortized on a straight-line basis over the remaining lease term, or the asset's
estimated useful life, whichever is shorter. All other

    Additions, major renewals and betterments are capitalized. Repair and
maintenance costs are expensed as incurred. Upon sale or retirement of property
and equipment, the cost and accumulated depreciation are removed from the
appropriate accounts and any corresponding gain or loss is included in income in
the year the asset is disposed.
 
INTANGIBLES
 
    Intangibles are comprised primarily of costs in excess of the fair value of
net assets acquired, acquisition-related costs, financing fees and
noncompetition agreements related to acquisitions. Intangible assets are being
amortized over periods ranging from 10 to 25 years. At December 31, 1997 and
1998, accumulated amortization related to intangibles totalled $65,014 and
$1,624,534, respectively.
 
LONG-LIVED ASSETS
 
    The carrying value of long-lived assets is periodically reviewed by
management, and impairment losses, if any, are recognized when the expected
nondiscounted future operating cash flows derived from such assets are less than
their carrying value. During the year ended December 31, 1996, the Company
adopted Statement of Financial Accounting Standards "SFAS" No. 121, "Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed
of". SFAS No. 121 requires that long-lived assets and certain identifiable
intangible assets to be held and used be reviewed for impairment whenever events
or changes in circumstances indicate the carrying amount of such assets may not
be recoverable. The adoption of SFAS No. 121 did not have any impact on the
financial position, results of operations or cash flows of the Company.
 
INCOME TAXES
 
    In April 1998, the Company converted its tax status from an S Corporation
under Section 1361 of the Internal Revenue Code to a C Corporation status (the
"Conversion"). Upon conversion, the Company is required to pay federal and state
corporate income taxes on its taxable income.
 
    Upon the completion of the Conversion, the Company recognized deferred taxes
in accordance with the liability method of accounting for income taxes. Under
this 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.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES , CONTINUED:
    For periods prior to the Conversion, the Company did not pay federal
corporate income taxes on its taxable income. Instead the shareholders were
individually liable for the federal and state income taxes based on the
Company's taxable income. For state income tax purposes, the Company was
required to pay an S Corporation tax based on 1.5% of taxable income. This state
tax liability is included in the provision for income taxes for periods prior to
the Conversion.
 
DEFERRED WARRANTY INCOME
 
    The Company offers its customers an optional separately purchased warranty
program for its commercial roofing systems. Revenue from the warranty program is
recognized over the 20 year warranty period. Warranty repair expenses under the
program are charged to expense as incurred.
 
ENVIRONMENTAL RESERVE
 
    The Company accrues for losses associated with environmental remediation
obligations when such losses are probable and reasonably estimable. Accruals for
estimated losses from environmental remediation obligations generally are
recognized no later than completion of the remedial feasibility study. Such
accruals are adjusted as further information develops or circumstances change.
Cost of future expenditures for environmental remediation obligations are not
discounted.
 
SELLING, GENERAL AND ADMINISTRATIVE EXPENSES
 
    Selling, general and administrative expenses include all costs associated
with marketing and distributing the Company's products. Also included in
selling, general and administrative expenses are research and development costs.
Research and development costs incurred in developing and improving product
formulae are charged to expense in the year incurred. Total research and
development costs were $320,961, $320,275 and $1,037,703 for the years ended
December 31, 1996, 1997 and 1998, respectively.
 
ADVERTISING AND PROMOTION COSTS
 
    All costs associated with advertising and promoting products are expensed in
the year incurred and are included in selling, general and administrative
expenses. Advertising and promotion expenses were $1,026,698, $1,004,221 and
$3,025,741 for the years ended December 31, 1996, 1997 and 1998, respectively.
 
FOREIGN CURRENCY TRANSLATION
 
    The assets and liabilities of the Company's wholly-owned Canadian
subsidiaries are translated from Canadian dollars to U.S. dollars using exchange
rates in effect at the balance sheet date. Revenues and expenses are translated
using average exchange rates prevailing during the period. The effect of the
unrealized exchange rate fluctuations on translating foreign currency assets and
liabilities into U.S. dollars are accumulated as a separate component of
shareholders' equity. Gains and losses resulting from foreign currency
transactions are included in operations. The aggregate foreign exchange gains
included in operations were $48,700 for the year ended December 31, 1998.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES , CONTINUED:
FINANCIAL INSTRUMENTS AND RISK MANAGEMENT
 
    Financial instruments which potentially expose the Company to concentration
of credit risk consist primarily of cash and cash equivalents and trade
receivables. The Company currently maintains substantially all of its day-to-day
operating cash balances with major financial institutions. At times, cash
balances may be in excess of Federal Depository Insurance Corporation ("FDIC")
insurance limits. Cash equivalents principally consist of money market funds on
deposit with major financial institutions.
 
    Concentration of credit risk with respect to trade receivables is derived
from the Company's largest customer, which represents approximately 15% and 8.2%
at December 31, 1997 and 1998, respectively. This customer also accounted for
approximately 12% of net sales in fiscal year 1996, 15% of net sales in fiscal
year 1997 and 8% of net sales in fiscal year 1998. However, the majority of the
Company's customers are geographically diverse roofing distributors and
contractors located throughout the United States and eastern Canada, which
limits the extent of trade credit risk. The Company also maintains credit
insurance that provides substantial reimbursement for actual credit losses
relating to its Henry Coatings Division. In addition, the Company controls
credit risk through credit approvals, credit limits and monitoring procedures.
 
THE VALUE OF FINANCIAL INSTRUMENTS
 
    SFAS No. 107, "Disclosure About Fair Value of Financial Instruments",
requires disclosure of fair value information about most financial instruments
both on and off the balance sheet, if it is practicable to estimate. SFAS No.
107 excludes certain financial instruments such as certain insurance contracts
and all non-financial instruments from its disclosure requirements. A financial
instrument is defined as a contractual obligation that ultimately ends with the
delivery of cash or an ownership interest in an entity. Disclosures regarding
the fair value of financial instruments are derived using external market
sources, estimates using present value or other valuation techniques. Cash,
accounts receivable, accounts payable, accrued liabilities and short-term debt
are reflected in the financial statements at fair value because of the
short-term maturity of these instruments. The Company's long-term debt is
primarily comprised of senior notes with a carrying value of $85 million at
December 31, 1998. The fair value of the senior notes was $100.5 million at
December 31, 1998.
 
    The Company has issued a standby letter of credit relating to its business
insurance and is contingently liable for approximately $409,000. The standby
letter of credit is in force for the term of the insurance policy, and reflects
the current fair value.
 
USE OF ESTIMATES AND ASSUMPTIONS
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities, and
disclosure of contingent assets and liabilities at the date of the financial
statements, and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
COMPREHENSIVE INCOME
 
    During 1998, the Company adopted the provisions of SFAS No. 130, "Reporting
Comprehensive Income." SFAS No. 130 establishes guidelines for the reporting and
display of comprehensive income and

its components in the financial statements. Comprehensive income, as defined,
includes all changes in shareholders' equity during a period from non-owner
sources. The only component of comprehensive income not included in the
Company's operating results relates to the change in the cumulative translation
adjustment related to the foreign currency effects of the Canadian operations
acquired during 1998 as part of the Acquisition as discussed in Note 2.
 
RECENT ACCOUNTING PRONOUNCEMENTS
 
    In March 1998, the American Institute of Certified Public Accountants
("AICPA") issued Statement of Position ("SOP") No. 98-1, "Software for Internal
Use", which provides guidance on accounting for the cost of computer software
developed or obtained for internal use. SOP No. 98-1 is effective for financial
statements for fiscal years beginning after December 15, 1998. The Company does
not anticipate that the adoption of SOP No. 98-1 will have a material impact on
the Company's financial position, results of operations or cash flows.
 
    In April 1998, the AICPA issued SOP No. 98-5, "Reporting on the Costs of
Start-up Activities". SOP No. 98-5, which is effective for fiscal years
beginning after December 15, 1998, provides guidance on the financial reporting
of start-up costs and organization costs. It requires costs of start-up
activities and organization costs to be expensed as incurred. As the Company has
expensed these costs historically, the adoption of this standard will not have a
significant impact on the Company's financial position, results of operations or
cash flows.
 
    In June 1998, the Financial Accounting Standards Board ("FASB") issued SFAS
No. 133, "Accounting for Derivatives and Hedging Activities", which establishes
accounting and reporting standards for derivative instruments, including certain
derivative instruments embedded in other contracts (collectively referred to as
derivatives) and for hedging activities. SFAS No. 133 is effective for all
fiscal quarters of fiscal years beginning after June 15, 1999. The Company does
not expect the adoption of this statement to have a significant impact on the
Company's financial position, results of operations or cash flows.
 
2. BUSINESS ACQUISITION AND NOTE OFFERING:
 
    On April 22, 1998, the Company completed the acquisition of Monsey Bakor and
its subsidiaries (the "Acquisition") which are engaged in the distribution and
manufacture of roof coatings, adhesives and membranes, and waterproofing and air
barrier systems, for residential and commercial applications. The cash purchase
price was $42,750,000 with an additional $3,227,000 paid at closing to certain
selling shareholders of Monsey Bakor for noncompetition agreements. A selling
shareholder also purchased 22,500 shares of redeemable convertible preferred
stock of the Company for $600,000 cash as more fully discussed in Note 12. The
Acquisition was accounted for using the purchase method of accounting.
 
    Concurrent with the Acquisition, the Company conducted a senior note
offering the (the "Offering") in the aggregate principal amount of $85,000,000
as more fully discussed in Note 5.
 
    In accordance with the requirements of Accounting Principles Board ("APB")
Opinion No. 16 "Business Combinations," the following unaudited pro forma
summary presents the results of operations of the Company as if the Acquisition
and Offering had occurred as of the beginning of each period presented. The pro

    On April 22, 1998, the Company privately issued and sold $85,000,000 of
senior notes (the "Senior Notes") due in 2008. Interest on the Senior Notes is
payable semi-annually a 10% per annum. In October 1998, the Company completed an
exchange offer for all of the Senior Notes. The terms of the new Senior Notes
are identical in all material respects to the original private issue. The
proceeds from the offering were used to (i) retire existing Company bank debt,
(ii) retire existing Company subordinated shareholder debt, (iii) acquire Monsey
Bakor, (iv) retire a substantial portion of Monsey Bakor's then-existing bank
debt with (v) the remainder providing additional working capital.

    On October 1, 1997, Henry Company granted the Warner W. Henry Living Trust
warrants to purchase an aggregate of 400,000 shares of Henry Company capital
stock, consisting of 12,000 shares of Class A common stock and 388,000 shares of
common stock (the "Warrants"). The Warrants expire on September 30, 2012 and may
be exercised in whole or in part at variable and increasing exercise prices over
the term of the warrants. The current and maximum exercise prices for both Class
A common stock and common stock are $12.94 and $38.82 per share, respectively.
 
    The warrants have an initial exercise price that exceeds the fair value of
the capital stock at the date of grant. The grant date present value of each
warrant is estimated at 11 CENTS or an aggregate of $44,000 using the
Black-Scholes pricing model, using the following assumptions: risk-free interest
rate at 6.0%; expected warrant life of 15 years; volatility of 20.0%; forfeiture
rate zero (0); no expected dividends; and no adjustments for nontransferability.
As of December 31, 1998, no warrants have been exercised.
 
12. REDEEMABLE CONVERTIBLE PREFERRED STOCK:
 
    In connection with the Acquisition, the Company sold 22,000 shares of
redeemable convertible preferred stock in the Company to Joseph T. Mooney, Jr.
for $600,000. The Company is obligated, upon the exercise of Mr. Mooney's put
option, to redeem the stock for cash in annual amounts of $500,000 beginning in
2004 and aggregating $3,000,000, or for $3,000,000 upon the death of Mr. Mooney.

are convertible into shares of Common Stock. The fair value recorded for the
issuance of the preferred stock represents the estimated present value of the
redemption payments.
 
    The carrying amount of the Preferred Stock is being increased by periodic
accretions so that the amount reflected in the balance sheet will equal the
mandatory redemption amount at the redemption date.
 
13. SEGMENT AND GEOGRAPHIC INFORMATION:
 
    During 1998, the Company adopted SFAS No. 131, "Disclosures About Segments
of an Enterprise and Related Information", which requires the Company to report
information about its operating segments using a management approach.
 
    The Company manages its business through two reportable segments, or primary
business units with separate management teams, infrastructures, marketing
strategies and customers. The Company's primary business units are: the Henry
Coatings Division, which develops, manufactures and markets roof and driveway
coatings and paving products, industrial emulsions, air barriers, and specialty
products; and the Resin Technology Division, which develops, manufactures and
sells polyurethane foam for roofing and commercial uses.
 
    The accounting policies of the reportable segments are the same as those
described in Note 1 of the Notes to Consolidated Financial Statements. The
Company evaluates the performance of its operating segments based on net sales,
gross profit and operating income. Intersegment sales and transfers are not
significant.

14. GUARANTOR CONDENSED CONSOLIDATING FINANCIAL STATEMENTS:
 
    In connection with the Offering in April 1998, the Company's United States
subsidiaries, Monsey Products Co., Kimberton Enterprises, Inc. and Monsey
Products of Arizona LLC (the "Guarantor Subsidiaries") are unconditional
guarantors, on a full, joint and several basis, of the Company's debt
represented by the Senior Notes. The Company's Canadian subsidiaries are not
guarantors of the Senior Notes. Effective December 31, 1998, the Company merged
Monsey Products Co. and Monsey Products of Arizona LLC into Henry Company; as a
result, Kimberton Enterprises Inc. is the only Guarantor.
 
    Condensed consolidating financial statements of the Guarantors, from the
date of the Acquisition, are combined with the Henry Company and are presented
below. Separate financial statements of the Guarantor Subsidiaries are not
presented and the Guarantor Subsidiaries are not filing separate reports under
the Exchange Act because the Subsidiary Guarantors have fully and
unconditionally guaranteed the Senior Notes on a joint and several basis under
the guarantees and management has determined that separate financial statements
and other disclosures concerning the Guarantor Subsidiaries are not material to
investors.
