ITEM 1. BUSINESS

                                    OVERVIEW

     Burke Industries, Inc. (the "Company" or "Burke"), headquartered in San 
Jose, California, is a leading, diversified manufacturer of highly 
engineered, rubber, silicone and vinyl-based (herein "elastomer") products. 
Through its vertically integrated operations and reputation for quality 
elastomer-based products, Burke has become (i) the largest domestic producer 
of precision silicone seals for commercial and military aircraft ("Aerospace 
and Defense Products"), (ii) a leading nationwide producer of both rubber and 
vinyl cove base and floor covering accessories for commercial and industrial 
applications ("Flooring Products") and (iii) a value-added producer of 
high-performance silicone hose, roofing and membrane products for the 
heavy-duty truck, commercial building and fluid containment industries 
("Commercial Products").

                                     HISTORY

     The Burke Rubber Company was founded in 1942 as a family-owned 
manufacturer of custom industrial rubber products. By the early 1950s, Burke 
manufactured a proprietary line of rubber floor tile and cove base as well as 
custom-molded rubber products. The Burke product line subsequently grew to 
include flexible membrane products for industrial uses, as well as engineered 
elastomer-based products for defense-related applications. In 1970, Burke 
developed an improved roofing and fluid barrier technology based upon 
DuPont's patented Hypalon elastomer polymer. The Company was renamed Burke 
Industries, Inc. in 1972 to reflect its broadened base of business.

     The Company began expanding beyond its traditional product lines with 
its acquisition of the silicone-based aerospace seal and automotive hose 
production assets of Purosil, Inc. ("Purosil") in March 1993. In 1995, 
recognizing that the seals segment of the aerospace industry was fragmented 
and ripe for consolidation, Burke sought to expand its position in the 
category through the acquisition of assets of two former industry leaders 
that were then experiencing financial difficulties: California-based SFS 
Industries and Massachusetts-based Haskon Corporation. Purosil, SFS and 
Haskon had each been an independent producer of precision silicone aerospace 
components, and together had over 100 years of service to the commercial and 
military aerospace industry.

     In April 1998, the Company acquired from Sovereign Specialty Chemicals, 
Inc. ("Sovereign") all of the outstanding capital stock of Mercer Products 
Company, Inc. ("Mercer"). For many years, Mercer has been a leading 
manufacturer of plastic and vinyl flooring products such as vinyl cove base, 
transitional and finish mouldings, corners, stair treads and other 
accessories. Management believes that the highly successful vinyl cove base 
and moulding product lines and the strong presence in the eastern United 
States developed by Mercer complement the Company's position as the dominant 
producer of rubber cove base and floor covering accessories in the western 
United States.

     Mercer was merged with and into the Company, effective August 12, 1998. 
Burke has integrated Mercer's product lines into its own and now operates its 
Flooring Products business throughout the nation under the name BurkeMercer 
Flooring Products.

     Mercer represents the fifth acquisition completed by Burke's current 
management team over the last six years. Burke's integration of these 
acquisitions has led to a dominant position in the aerospace 

                                       1
<PAGE>

seals market, opened new markets for its Flooring Products business, improved 
operating efficiencies, consolidated overhead and strengthened technical 
capabilities.

     In August 1997, the Company entered into a recapitalization (the 
"Recapitalization") pursuant to which the Company was recapitalized by means 
of a merger and J.F. Lehman Equity Investors I, L.P. ("JFLEI") and its 
affiliates became the owners of approximately 65% of the common equity of the 
Company, without giving effect to the exercise of certain options issued to 
management of the Company.

                                INDUSTRY OVERVIEW

     The Company operates within one industry segment, elastomer products. 
Virtually every industry contains applications for elastomeric products. 
These products are used wherever there is a need for materials that are 
flexible, yet retain their original shape and other properties. Elastomeric 
products tend to be a small portion of the total cost of any product, yet can 
be critical to a successful design. The Company believes that the demand for 
elastomeric products will continue to grow as the performance requirements of 
various products are increased.

     The Company serves a number of industries with significant usage of 
highly-engineered elastomer-based products. Customers in these industries 
value quality, on-time performance, and the ability to provide technical 
problem-solving capabilities. The increasingly complex product design effort 
of companies in these and other industries provides ongoing and new 
opportunities for elastomeric product applications. The Company believes that 
its technical resources, experience, and reputation provide it with a 
competitive advantage in seeking to provide products to these industries.

                              PRODUCTS AND MARKETS

     Within the elastomer products industry segment, the Company is organized 
into two business segments: silicone and organic products. The Company's 
products are further organized into three product groups: Aerospace and 
Defense Products, which produces precision silicone seals and other products 
used on commercial and military aircraft; Flooring Products, which produces 
and distributes rubber and vinyl cove base and other floor covering accessory 
products; and Commercial Products, which produces various intermediate and 
finished silicone and organic rubber products. Burke is a leader in a number 
of markets where the Company's vertically integrated production capabilities 
and design, engineering and manufacturing expertise result in a strong 
competitive position.

AEROSPACE AND DEFENSE PRODUCTS

     Operating out of Santa Fe Springs, California and Taunton, 
Massachusetts, Burke, through its Aerospace and Defense Products business, is 
the leading domestic manufacturer of two principal product lines: highly 
engineered elastomer-based seals for commercial and military aircraft and 
low-observable, radar-absorbing materials for stealth military applications. 
Burke's non-stealth aerospace components are marketed under the SFS and 
Haskon trade names. Burke first entered the aerospace market in 1993 with its 
purchase of Purosil. Aerospace and Defense Products sales increased from $3.6 
million in 1993 to $33.8 million in 1998.

     PRODUCTS

     Burke's major aerospace seals products include: aerodynamic seals for 
commercial and military airframes, firewall seals for aircraft engines and 
nacelles, aircraft door and hatch seals, inflatable seals for cockpit 
canopies and large openings, aircraft window seals, and aircraft conductive 
seals for 

                                       2
<PAGE>

electromagnetic interference survivable conditions. Burke's product line 
ranges from the most basic extruded seals, costing less than $100, to 
exceptionally complex seals which may cost in excess of $10,000. Burke's 
design and engineering teams have a history of developing solutions for 
difficult sealing and shielding problems. Burke's silicone seals are also 
reinforced (if required) with a variety of materials including Kevlar, 
Dacron, Nomex, ceramic cloth, fiberglass, conductive fabrics, metal mesh, 
nylon and other materials which accommodate their demanding applications.

     During the late 1980s and early 1990s, SFS invested significant capital 
towards the research and development of radar-absorbing and signature-masking 
composite materials. This initial research and development established SFS as 
the technological leader in this niche defense-related area. Burke has 
continued the development of this technology since its acquisition of SFS and 
Haskon in 1995. Generally, Burke works on an exclusive basis with the United 
States military to test and develop these highly engineered and technical 
materials. Once a contract has been awarded, Burke has historically become 
the sole supplier to the United States government as an approved defense 
contractor. Based on its history and the Company's proven record in this 
area, management believes that Burke will remain a critical partner in 
product development opportunities in this sector. Burke maintains a 
classified area within the Santa Fe Springs facility where stealth technology 
products are developed, manufactured and tested.

     MARKETS AND CUSTOMERS

     Burke's silicone seals are sold directly to manufacturers of commercial 
and military aircraft, aerospace component distributors and the United States 
government. Burke has maintained its leading position in this market through 
its advanced in-house design, engineering, technical and production 
capabilities coupled with superior customer service. The engineering staff at 
Burke works directly with OEMs to design custom silicone sealing 
applications. Burke's Aerospace and Defense products are designed by Burke 
engineers in accordance with precise OEM specifications and quality 
requirements. Products are rigorously tested against ISO and OEM standards by 
Burke and its customers before final approval. In 1998, the top five 
customers of the Aerospace and Defense Products division accounted for $23.2 
million in net sales, representing 21.7% and 68.9%, respectively, of the 
Company's total and the Aerospace and Defense Product division's net sales in 
that year.

     Boeing is the single largest customer of Aerospace and Defense Products, 
and management believes Burke is likewise the leading supplier of these 
products to Boeing. In addition to Boeing, the Company produces seals for 
every major commercial aircraft manufacturer in the world and for 
substantially all major military manufacturers in the United States, 
including McDonnell Douglas (now Boeing), Lockheed Martin, Northrop Grumman, 
Airbus Industries, Pratt & Whitney, General Electric, Gulfstream, Bombardier 
and B.F. Goodrich Aerostructures. As a result, Burke's products have been 
designed into some of the most successful commercial and military aircraft in 
the world, including the Boeing 717, 737, 747, 757, 767 and 777, the 
McDonnell Douglas DC and MD series, the Northrop Grumman F-14 and the 
Lockheed Martin L1011.

     Burke's advanced Aerospace and Defense Products business has 
successfully introduced several technologies in use by branches of the United 
States Navy, Air Force and Army. These include radar-absorbing seals 
and other composite materials utilized on the B-2 bomber, the F-22 
fighter and naval surface ships. Ground-based and amphibious vehicle 
applications are also being developed. The Burke radar-absorbing material 
technology has potentially much broader applications than are currently in 
use, and the Company is presently involved in initiatives that management 
believes will greatly expand the market for its advanced Aerospace and 
Defense Products business.


                                       3

     The Northrop Grumman B-2 radar-resistant materials program provides a 
solid base for expansion of Burke's Aerospace and Defense business. Burke's 
revenues from this program are generated both by new aircraft production and 
by replacement materials applied as part of the repair or scheduled 
maintenance of the aircraft. Burke has also been qualified to supply the F-22 
program. The F-22 is the latest generation United States Air Force fighter 
aircraft and is designed to replace the F-15 as the premier fighter in the 
United States military arsenal in approximately two years. However, both the 
B-2 bomber and the F-22 fighter are subject to continuous budgetary scrutiny 
and Burke's ability to expand its Aerospace and Defense Products business 
could be limited if either of these programs were to be curtailed or 
eliminated.

     The advanced Aerospace and Defense Products business is also in the 
final phase of redesign and qualification for the "over-wing-fairing" seal 
for the B-1 bomber. Flight qualification will be followed by production 
proposals in 1999. The Company has also bid on a contract to develop seals 
for the new Joint Strike Fighter (JSF) program. Both Boeing and Lockheed 
Martin have been selected as the finalists for this program which is 
ultimately expected to procure approximately 3,000 multi-service aircraft for 
the United States Air Force, Marine Corps and Navy and the United Kingdom 
Royal Navy. The program is scheduled for production after the year 2005.

     COMPETITION

     Burke is the largest domestic supplier of highly-engineered silicone 
seals for the aerospace OEM market and aftermarket. Burke's domestic 
competitors are primarily small, privately-held companies which generally 
lack Burke's track record, long-term OEM relationships and capabilities. 
These competitors include Kirkhill Rubber Company, which was purchased by 
Esterline Technologies in 1998, Chase-Walton Elastomers, Inc. and Elastomeric 
Silicone Products, which was purchased by Bestobell Aviation in 1997. 
Additionally, the Company has two principal European competitors, Dunlop 
France S.A. and Bestobell Aviation, of the United Kingdom, which enjoy 
significant market share among European aircraft manufacturers, including 
Airbus Industries.

     Management believes that Burke's long-standing customer relationships, 
unique design capabilities and superior product quality will continue to 
support its position as the leading supplier of engineered silicone seals 
within this fragmented market.

     Burke is one of only a few companies with the combination of knowledge 
and manufacturing capabilities required to develop, test and manufacture 
engineered elastomer-based products to military specifications. Many of 
Burke's advanced Aerospace and Defense Products are classified in nature, and 
in many cases project leaders return to previous classified product suppliers 
for a preliminary assessment of future development opportunities.

FLOORING PRODUCTS

     Burke is a leading producer and distributor of specialty rubber and 
vinyl flooring accessory products for use in commercial markets. Flooring 
Products sales were $41.1 million in 1998, comprising 38% of the Company's 
total net sales.

     Burke's trademark BurkeBase has enjoyed a dominant market share in the 
western United States since the early 1950s and is well known throughout the 
industry. Burke extended its Flooring Products lines beyond rubber products 
through the Mercer acquisition. Founded in 1958, and headquartered in Eustis, 
Florida, Mercer established itself as a leading manufacturer of plastic and 
vinyl products such as vinyl and rubber wall base, transitional and finish 
mouldings, stair treads and other accessories. Mercer also sold a range of 
related adhesive products. The product and distribution lines developed by 
Mercer strongly complement the Company's Flooring Products business. While 
the Company has been the dominant producer of rubber cove base and floor 
covering accessories in the western United States, Mercer has been a leading 
supplier to the vinyl wall base and moulding products markets and developed a 
particularly strong sales presence in the eastern United States.

     PRODUCTS

     The combined line of BurkeMercer Flooring Products consists of a 
full range of commercial rubber and vinyl flooring products and accessories 
including rubber and vinyl cove base, flooring tiles, stair treads, corners, 
shapes, special application adhesives and newly developed luminescent 
emergency lighting accessories sold under the BurkeEmerge trademark. 
BurkeMercer flooring and flooring accessory products are generally recognized 
by architects, builders, and contractors as the highest-quality commercial 
rubber flooring and flooring accessory products available in terms of 
construction, durability and ease of installation. In its principal markets, 
BurkeMercer cove base is utilized in most commercial applications using 
resilient tile flooring and virtually all commercial applications involving 
carpeting. Other BurkeMercer flooring products are employed in commercial and 
institutional settings where durability and resilience are of primary 
importance.

     Rubber flooring products are generally more expensive than vinyl 
products due to their material and manufacturing cost but yield a 
longer-lasting product. However, vinyl flooring products are extremely 
popular for less demanding applications and are the predominant commercial 
flooring construction material in geographic regions outside of the western 
United States. The addition of a vinyl cove base product line creates a 
lower-cost, complementary offering targeted at less demanding, more 
cost-sensitive applications.

     MARKETS AND CUSTOMERS

     BurkeMercer Flooring Products are sold primarily to dealers and 
distributors in the western United States and through a network of flooring 
products distributors in other regions. In addition to the San Jose, 
California and Eustis, Florida manufacturing facilities, the Company has 
distribution facilities in Santa Fe Springs, California, Rancho Cucamonga, 
California, Bensonville, Illinois, and South Kearny, New Jersey. In 1998, the 
top five customers of the Flooring Products division accounted for $9.7 
million in net sales, representing 9.0% and 23.5%, respectively, of Burke's 
total and the Flooring Products division's net sales in that year.

     COMPETITION

     While there are a number of companies, both large and small, servicing 
the floor covering market, Burke is the largest producer of rubber cove base 
in the western United States. Burke's focus over many years on this 
specialized niche has created significant brand awareness and customer 
loyalty. The Mercer acquisition increases Burke's competitive advantage by 
adding several new vinyl-based product lines that have significant brand 
awareness and customer loyalty in the eastern United States. Burke's primary 
competitors in flooring accessory products include Roppe Corporation, 
Johnsonite, Flexco and Vinyl Plastics Incorporated.

COMMERCIAL PRODUCTS

     Burke's Commercial Products business serves end markets with both 
intermediate and finished silicone and organic rubber-based compounds and 
products. Commercial Products net sales increased from $14.8 million in 1993 
to $32.2 million in 1998, and represented 30% of the Company's total net 
sales in 1998.

     PRODUCTS

     PUROSIL PRODUCTS. Burke manufactures and markets a wide range of private 
label and Purosil-branded engineered silicone hose products for 
high-pressure, heat-sensitive applications. These high-performance products 
are sold primarily to OEMs and the aftermarket for heavy-duty trucks and 
buses. Burke was the first silicone hose producer in the industry to become 
ISO 9002 certified and is preparing for QS 9000 certification. The Company 
guarantees the performance of certain higher quality silicone truck hoses for 
1,000,000 miles and experiences negligible product returns and warranty 
claims each year. The Company also manufactures silicone hose products for 
applications in the powerboat, potable water and food service industries.

     New product development is an important focus within this group. Purosil 
has responded to recent market demand with newly designed 
charged-activated-coupling and knitted hose products for specific 
applications within the Class 8 truck market. These additions have 
strengthened the silicone hose product line and increased Burke's penetration 
of the OEM market.

     Burke leased an additional facility of approximately 56,000 square feet 
beginning in mid 1998. This facility is devoted to the manufacture and 
distribution of Purosil products and is expected to help to increase 
efficiency and customer service levels for all of the Company's 
silicone-based products.

     MEMBRANE PRODUCTS. Burke's membrane products business utilizes the 
Company's elastomer-based manufacturing expertise to produce high-end, 
single-ply commercial roof-covering systems and flexible liner membranes. 
Commercial roofing systems are sold into the new roofing and re-roofing 
markets under the Burkeline trade name and have been installed in large and 
small commercial and institutional facilities around the world. The Company's 
membrane products are also used as reservoir liners and floating potable and 
waste water covers.

     Burke's roofing and liner membrane systems are designed with DuPont's 
patented Hypalon polymer material, which is an extremely durable and flexible 
material, widely regarded as the highest-quality single-ply product available 
in the commercial roofing and membrane market. Burke's membrane products 
typically incorporate structural fabric laminated between thin layers of 
Hypalon. Burkeline 


                                       6
<PAGE>

roofing systems are installed by Burke-approved contractors and technical 
assistants and are fully warranted for up to 30 years.

     Membrane liners and covers are used primarily for protective purposes in 
potable water and wastewater projects. The liners and covers are most often 
used to protect against contamination of potable water during its storage and 
transfer. Hypalon is one of the few polymers which meets environmental 
standards regarding sanctioned potable water contact materials. Burke's 
in-house technical and engineering groups work directly with municipal 
engineers and with distributors and fabricators to assist in the design, 
testing and selection of the final product. Burke also manufactures and 
provides a full line of custom-made shrouds, gas vents, adhesives and other 
components necessary to produce a complete system package.

     CUSTOM PRODUCTS. The custom products group within Burke's Commercial 
Products division has capitalized on the Company's sophisticated formulation 
and production capabilities to become a value-added partner that collaborates 
closely with its customers in designing application-specific advanced 
products in both the silicone and organic rubber products markets. The group 
focuses on identifying high-margin products that complement its existing 
product lines and utilize excess production capacity. These custom products 
are typically complex blending and compounding formulations serving as 
intermediate or finished products for manufacturers of specialty rubber 
products and include oil drilling equipment components, road tape, rocket 
motor insulation and surface ship bow domes.

     MARKETS AND CUSTOMERS

     Management believes that the Company is the only approved supplier of 
silicone hoses to Mack Trucks. Burke's automotive hose products are also 
designed and specified into model builds of other major Class 8 truck OEMs 
including Peterbilt and Freightliner.

     Burke's membrane roofing products are sold both to distributors and 
directly to end-users who favor higher-quality roofing systems and who select 
Burke based on its reputation for quality. These roofing systems are 
typically employed in high value-added applications where quality, as 
measured by durability and ease of maintenance, is critical.

     Burke's liner membrane products are used in applications which are 
typically outsourced by municipalities on a bid basis and take several months 
to complete. Burke's covers and liners are sold to distributors and 
fabricators who heat weld the Hypalon-constructed sheets together to create a 
final product. It is not unusual for Burke to work with multiple distributors 
who are bidding for the same municipal project.

     Most of Burke's customers of the custom products unit are repeat users 
and range from large industrial companies to niche manufacturers producing 
specialized elastomeric products. Burke has developed long-standing 
relationships with a broad base of customers as a supplier of both 
intermediate and finished products whose technical complexities are suited to 
its unique capabilities. Burke markets these products using direct and 
independent sales representatives in both the United States and Europe. In 
1998, the top five customers of the Commercial Products division accounted 
for $8.6 million in net sales, representing 8.1% and 26.9%, respectively, of 
the Company's total and the Commercial Products division's net sales in that 
year.

     COMPETITION

     The marketplace for engineered silicone hose applications is supplied by 
three principal companies: Flexfab Horizons International, Thermopol 
Incorporated and the Company.

     In both roofing and liner systems, Burke competes with other 
Hypalon-based product manufacturers and with lower-cost alternatives. Leading 
manufacturers of these alternative systems include JPS Elastomerics Corp. and 
Carlisle Companies, Inc. Each has significant single-ply membrane roofing 
businesses and emphasize their membrane products manufactured from 
alternative materials as lower-cost, higher-volume products. Their Hypalon 
offerings represent a small portion of their aggregate sales.

     There are a number of manufacturers that compete in custom-mixing and 
product formulation business, although management believes that only a few 
match Burke's comprehensive capabilities in terms of its research, design, 
materials compounding, engineering and laboratory testing resources. Burke's 
custom products product line has developed a reputation for solving complex 
formulation problems and is staffed with experienced compounding 
professionals.

                               SALES AND MARKETING

     Burke's sales and marketing personnel are organized by product lines. 
Based on the nature of the markets served and the established distribution 
channels in a particular segment, products are sold either directly to 
end-users or through distributors and independent sales representatives. 
Burke's Aerospace and Defense Products business has long-standing direct 
relationships with OEMs and aftermarket suppliers to the aerospace industry 
and supports these relationships by integrating its engineering and operating 
groups during the design, tooling and production phases of a customer's 
project. Burke solidifies its relationships through ongoing technical support 
throughout the life of a project.

     Burke's Flooring Products business sells through a direct sales effort 
and through flooring products distributors. Management believes the recently 
consolidated BurkeMercer product line will enable Burke to (i) increase its 
number of first-tier distributors, specifically in the midwest and east, who, 
in the past, have not carried Burke products due to Burke's lack of a vinyl 
product offering, and (ii) displace other vinyl suppliers with distributors 
that already carry Burke's rubber flooring products line. The Flooring 
Products business currently utilizes 16 direct sales representatives who 
manage direct sales and orchestrate the Company's national marketing efforts 
through approximately 345 commercial flooring products distributor locations.

     Burke's Commercial Products businesses utilize several different sales 
and marketing approaches due to the scope of their product offerings. 
Purosil's high-performance silicone hoses are sold directly to OEMs in the 
heavy-duty truck and bus market. The Company also manufactures a number of 
"standard" product hoses which are marketed through sales representatives and 
a national network of distributors. The other commercial products that Burke 
produces are primarily sold through specialized in-house representatives 
adept at identifying potential customers who can benefit from Burke's 
vertically integrated manufacturing, compound formulation and engineering 
capabilities.

                                  MANUFACTURING

RAW MATERIALS

     Principal raw materials purchased by the Company for use in its products 
include various custom and standard grades of rubber, silicone gum and vinyl 
as well as the Hypalon polymer material. The 

                                       8
<PAGE>

Company has historically not experienced any significant supply restrictions 
and has generally been able to pass through increases in the price of these 
materials to customers. In 1995, however, the Company experienced a 
significant price increase in one of the raw materials used in the 
manufacture of one of its Flooring Products. Due to the competitive nature of 
the Flooring Products business and the Company's proprietary formula for this 
product, the Company was unable to fully pass this price increase along to 
its consumers and its gross margins for this product were adversely affected. 
Although the Company does not currently anticipate that it will experience 
any similar price increases for this or any other raw material used by the 
Company in the near future, there can be no assurance that such price 
increases will not occur and that the Company's results of operations will 
not be adversely affected thereby.

VERTICAL INTEGRATION

     Burke's operations are vertically integrated for the production of both 
silicone and organic rubber-based products. The Company's production process 
commences with the receipt of raw materials, followed by a variety of 
production steps which generally include mixing, milling, calendering (or 
extrusion or stripping), forming and molding and, in the case of silicone, 
roto-curing. Management believes Burke's vertical integration provides a key 
competitive advantage within the markets it serves.

                                OTHER INFORMATION

BACKLOG AND WARRANTY

     The Company's backlog consists of cancelable orders and is dependent 
upon trends in consumer demand throughout the year. Customer order patterns 
vary from year to year, largely because of annual differences in consumer 
end-product demand, marketing strategies, overall economic and weather 
conditions. Orders for the Company's products are generally subject to 
cancellation until shipment. As a result, comparison of backlog as of any 
date in a given year with backlog at the same date in a prior year is not 
necessarily indicative of sales trends. Moreover, the Company does not 
believe that backlog is necessarily indicative of the Company's future 
results of operations or prospects.

     The Company's warranty policy is to accept returns of products with 
defects in materials or workmanship. The Company will also accept returns of 
incorrectly shipped goods where the Company has been notified on a timely 
basis and, in certain cases, to maintain customer goodwill. In accordance 
with normal industry practice, the Company ordinarily accepts returns only 
from its customers and does not ordinarily accept returns directly from 
consumers. Certain of the products returned to the Company by its customers, 
however, may have been returned to those customers by consumers. The Company 
generally warrants its roofing products for two years, for which the related 
costs are not significant. In addition, the Company sells extended warranties 
on roofing products for ten to thirty years. During the three-year period 
ended January 1, 1999, the Company incurred insignificant warranty costs with 
respect to its roofing products.

EMPLOYEES

     At January 1, 1999, the Company employed 1,058 employees at its various 
locations, including 935 involved in manufacturing and manufacturing support 
and 74 involved in product sales. Employees at the Company's various 
locations receive comparable insurance and benefit programs. Burke's 
employees at the San Jose and Taunton locations are represented by the 
International Association of Machinists and Electrical Workers Unions, 
respectively. The collective bargaining agreement for the Taunton location 
was renegotiated in June 1997 for a three-year term and the agreement for the 
San Jose 

                                       9
<PAGE>

location was renegotiated in October 1997 for a three-year term. Burke's 
employees at the Eustis, Florida location are represented by the Glass, 
Molders, Pottery, Plastics and Allied Workers International Union. This 
collective bargaining agreement was renegotiated in December 1998 for a 
three-year term. The Company has not experienced a work stoppage due to a 
labor dispute since 1975 and management believes that the Company's 
relationships with its employees and unions are good.

PATENTS, TRADEMARKS, TRADE NAMES AND TRADE SECRETS

     The success of the Company's various businesses depends in part on the 
Company's ability to exploit certain proprietary patents, trademarks, trade 
names and trade secrets on an exclusive basis in reliance upon the 
protections afforded by applicable copyright, patent and trademark laws and 
regulations. The loss of certain of the Company's rights to such patents, 
trademarks, trade names and trade secrets or the inability of the Company 
effectively to protect or enforce such rights could adversely affect the 
Company. The duration of the Company's intellectual property rights is as 
follows:

ENVIRONMENTAL LIABILITY

     The Company is subject to various evolving federal, state and local 
environmental laws and regulations governing, among other things, emissions 
to air, discharge to waters and the generation, handling, storage, 
transportation, treatment and disposal of hazardous and non-hazardous 
substances and wastes. These laws and regulations provide for substantial 
fees and sanctions for violations and, in many cases, could require the 
Company to remediate a site to meet applicable legal requirements. In 

                                       10
<PAGE>

connection with the Recapitalization, JFLEI conducted certain investigations 
(including, in some cases, reviewing environmental reports prepared by 
others) of the Company's operations and its compliance with applicable 
environmental laws. The investigations, which included Phase I assessments 
(consisting generally of a site visit, records review and non-intrusive 
investigation of conditions at the subject facility) by independent 
consultants, found that certain facilities have had or may have had releases 
of hazardous materials that may require remediation. Pursuant to the Merger 
Agreement (as defined below), the former shareholders of the Company have 
agreed, subject to certain limitations as to survival and amount, to 
indemnify the Company against certain environmental liabilities incurred 
prior to the consummation of the Recapitalization. Based in part on the 
investigations conducted and the indemnification provisions of the Agreement 
and Plan of Merger, dated as of August 13, 1997 (the "Merger Agreement") 
among JFLEI, JFL Merger Co. ("MergerCo") and certain former shareholders of 
the Company (pursuant to which the Company was recapitalized by means of a 
merger of MergerCo into the Company (the "Merger") with the Company surviving 
the Merger) with respect to environmental matters, the Company believes, 
although there can be no assurance, that its potential obligations relating 
to these environmental matters will not have a material adverse effect on its 
future financial position or results of operations.

     In connection with the Mercer acquisition, the Company conducted an 
environmental review of Mercer's operations and its compliance with 
applicable environmental laws. The review included a site visit to Mercer's 
manufacturing facility in Eustis, Florida and interviews with facility 
personnel regarding environmental matters. In addition, the Company reviewed 
existing environmental reports that included Phase I assessments, audits and 
limited soil and ground water sampling data. The environmental review 
revealed that Mercer's facilities have had, or may have had, releases of 
hazardous substances that may require remediation. Pursuant to the Stock 
Purchase Agreement, the former shareholders of Mercer have agreed, subject to 
certain limitations as to survival and amount, to indemnify the Company 
against certain environmental liabilities incurred prior to the purchase. 
Based, in part, on the environmental review conducted by the Company and the 
indemnification provisions of the Stock Purchase Agreement with respect to 
environmental matters, the Company believes, although there can be no 
assurance, that its potential obligations relating to these environmental 
matters will not have a material adverse effect on its future financial 
position or results of operations. The Company does not maintain a reserve 
for environmental liabilities.

ITEM 2. PROPERTIES

FACILITIES

     San Jose, California serves as the corporate headquarters for Burke as 
well as one of the manufacturing sites for the Flooring Products business and 
the organic rubber portion of the Commercial Products businesses. Santa Fe 
Springs, California is the manufacturing headquarters for Burke's silicone 
production activities and houses most of its Aerospace and Defense Products 
and all of its silicone Commercial Products businesses. Along with the 
industrial hose production, the Aerospace and Defense Products business 
classified development and production areas are also located at the Santa Fe 
Springs facility. The Taunton, Massachusetts facility is the manufacturing 
site for Burke's Haskon aerospace operations. This location provides Burke 
with an alternative eastern United States manufacturing presence for its 
aerospace customers.


                                       11

     Burke's Flooring Products are produced in San Jose, California and 
Eustis, Florida. In addition, the Company leases and operates large 
distribution centers in Santa Fe Springs, California, Rancho Cucamonga, 
California, Bensonville, Illinois and South Kearny, New Jersey.

     The Company believes that its facilities are in good condition and that 
the facilities, together with anticipated capital improvements and additions, 
are adequate for the Company's operating needs for the foreseeable future.

     As of March 15, 1999, Burke maintained operations at the following

     In addition to the facilities identified above, the Company leases a 
113,000 square foot facility in Modesto, California, which is subleased to 
the purchaser of the Company's custom-molded products business in connection 
with the sale of that business in 1996.

ITEM 3. LEGAL PROCEEDINGS

     The Company is routinely involved in legal proceedings related to the 
ordinary course of its business. Management does not believe any such matters 
will have a material adverse effect on the Company. The Company maintains 
property, general liability and product liability insurance in amounts which 
it believes are consistent with industry practices and adequate for its 
operations.

     On or about December 28, 1997, a former employee filed a complaint in 
the California Superior Court for the County of Santa Clara against the 
Company and certain of the Company's current and former officers and 
directors. On March 11, 1998, the plaintiff filed an amended complaint 
against the same defendants. The former employee alleges that he was induced 
to sell his stock in the Company to the Company and/or to the officer and 
director defendants in August 1996 through the use of allegedly false and/or 
misleading statements. The Company believes that such claims are without 
merit and intends to continue to vigorously defend such action. In this 
regard, on October 5, 1998, defendants answered the complaint and, in 
addition, filed a cross-complaint against the plaintiff for breach of 
contract. Defendants' cross-claim alleges that the plaintiff breached the 
terms of a general release he executed at the time he left the employ of the 
Company in 1996 and certain covenants set forth therein.

     On or about May 5, 1998, a former employee of Mercer filed a lawsuit in 
U.S. District Court Middle District of Florida against Mercer and Sovereign, 
the former owner of Mercer. The former employee made various claims for 
relief on the grounds that she was allegedly the victim of certain 

                                       12
<PAGE>

harassment, discrimination, retaliation and negligence. Pursuant to certain 
indemnification provisions contained in the Stock Purchase Agreement between 
the Company, Mercer and Sovereign, dated March 5, 1998, as amended by 
Amendment No. 1 to the Stock Purchase Agreement, dated April 21, 1998, Mercer 
tendered its defense to Sovereign and Sovereign agreed, through its counsel, 
to defend Mercer against the allegations asserted against Mercer by the 
former employee. Following Mercer's merger into the Company, the Company 
became a defendant in the lawsuit. In order to avoid the expenses associated 
with further litigation, including a possible trial, on or about February 2, 
1999, the parties entered into a confidential settlement agreement pursuant 
to which the plaintiff agreed voluntarily to dismiss her claims against the 
Company without any admission of liability on the part of the Company. 
Although the terms of the settlement agreement are confidential, the 
settlement agreement included no terms that have had, or will have in the 
future, any material impact on the Company's business, financial condition or 
results of operations.

COMMON EQUITY DIVIDENDS

     The Company's Common Stock is not listed or traded on any exchange. At 
January 1, 1999, there were approximately 13 holders of the Company's Common 
Stock.

     The Company has not paid any cash dividends on its Common Stock to date. 
The Company intends to retain all future earnings for use in the development 
of its business and does not anticipate paying cash dividends in the 
foreseeable future. The payment of all dividends will be at the discretion of 
the Company's Board of Directors and will depend upon, among other things, 
future earnings, operations, capital requirements, the general financial 
condition of the Company and general business conditions. The ability of the 
Company and its subsidiaries to pay dividends is restricted by the indentures 
governing the $110,000,000 principal amount of Senior Notes Due 2007 and the 
Floating-Rate Notes (defined below) and, with respect to the Common Stock, 
the Company's Articles of Incorporation.

RECENT SALES OF UNREGISTERED SECURITIES

     In connection with the Mercer acquisition, on April 17, 1998, the 
Company issued $30,000,000 principal amount of Floating Interest Rate Senior 
Notes due 2007 of the Company (the "Floating-Rate Notes") to NationsBanc 
Montgomery Securities LLC (the "Initial Purchaser"). The aggregate price to 
the public of the Floating-Rate Notes was $30,000,000 and the aggregate 
initial purchaser's discounts and commissions were $900,000 resulting in 
aggregate proceeds to the Company of $29,100,000. The Company sold the 
Floating-Rate Notes in reliance on the exemption provided by Section 4(2) of 
the Securities Act of 1933, as amended. The Initial Purchaser subsequently 
resold the Floating-Rate Notes in reliance on Rule 144A under the Securities 
Act of 1933, as amended. The Floating-Rate Notes were registered by the 
Company pursuant to a Registration Statement on Form S-4, File No. 333-36675, 
as filed with the Securities and Exchange Commission on June 19, 1998.

     In connection with the Mercer acquisition, the Company also sold 3,000 
shares of Series C 6% Convertible Preferred Stock ("Series C Convertible 
Preferred Stock") for aggregate consideration of $3 million. The Series C 
Convertible Preferred Stock was sold to all of the shareholders and 
warrantholders who elected to participate in the subscription offering. Upon 
the occurrence of certain triggering events, the holders of the Series C 
Convertible Preferred Stock are entitled to convert such shares into the 
Company's Common Stock at a price of $10 per share.

(7)  In calculating the ratio of earnings to fixed charges, earnings consist of
     income (loss) before income tax provision (benefit), cumulative effect of
     accounting change, extraordinary loss and discontinued operation plus fixed
     charges (excluding capitalized interest). Fixed charges consist of interest
     incurred (which includes amortization of deferred financing costs) whether
     expensed or capitalized and a portion of rental expense estimated to be
     attributable to interest. Earnings were insufficient to cover fixed charges
     by $5.8 million for fiscal year ended 1997.

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

     This Report contains certain forward-looking statements and information 
relating to the Company that are based on the beliefs of management as well 
as assumptions made by and information currently available to management. The 
words "anticipates," "believes," "estimates," "expects," "plans," "intends" 
and similar expressions, as they relate to the Company or its management, are 
intended to identify forward-looking statements. Such statements reflect the 
current views of the Company, with respect to future events and are subject 
to certain risks, uncertainties and assumptions, that could cause actual 
results to differ materially from those expressed in any forward-looking 
statement, including, without limitation: competition from other 
manufacturers in the Company's aerospace, flooring or commercial product 
lines, loss of key employees, general economic conditions and adverse factors 
impacting the aerospace industry such as changes in government procurement 
policies. Should one or more of these risks or uncertainties materialize, or 
should underlying assumptions prove incorrect, actual results may vary 
materially from those described herein as anticipated, believed, estimated or 
expected. The Company does not intend to update these forward-looking 
statements.

INTRODUCTION

     The following discussion and analysis should be read in conjunction with 
"Selected Historical Consolidated Financial Data" and the audited 
Consolidated Financial Statements of the Company and the notes thereto 
included elsewhere in this Report.

     The Company operates within one industry segment, elastomer products, 
and is organized into two business segments: silicone and organic products. 
The Company's products are organized into three product groups: Aerospace and 
Defense Products, which produces precision silicone seals and other products 
used on commercial and military aircraft; Flooring Products, which produces 
and distributes rubber and vinyl cove base and other floor covering accessory 
products; and Commercial Products, which produces various intermediate and 
finished silicone and organic rubber products.

     Burke entered the Aerospace and Defense Products business through the 
acquisition of Purosil's assets in 1993. The Company subsequently expanded 
its Aerospace and Defense Products business by purchasing the assets of two 
of its largest competitors, SFS and Haskon, in 1995. These acquisitions were 
completed in order to broaden Burke's Aerospace and Defense Products line and 
to incorporate advanced military stealth capability into this product group. 
Subsequent to these acquisitions, in 

                                      16
<PAGE>

December 1995, the Company integrated all of its aerospace operations in 
anticipation of increased demand as communicated by aircraft OEMs.

     In general, Aerospace and Defense Products seals revenues are driven by 
both the building of new aircraft by OEM manufacturers and the repair and 
replacement of existing aircraft ("aftermarkets"). OEMs typically depend on a 
select group of suppliers to provide their seal requirements, working closely 
with them to design the customized tooling necessary to satisfy the 
industry's rigorous product testing standards. As a result of the Company's 
consolidation efforts throughout the mid-'90s, Burke is now positioned as the 
leading seals supplier for the domestic commercial aircraft industry and is 
OEM-specified on virtually every existing commercial and military aircraft 
platform in production. Revenues of low-observable seals and materials are 
derived from both the retrofit of existing aircraft, such as the B-1 bomber 
and the initial installation and replacement of existing low-observable 
material on aircraft, such as the B-2 bomber.

     Historically, revenues in the Flooring Products business have been 
driven by both new commercial construction and the continuous repair and 
remodeling of existing commercial space. Until recently, operations have been 
concentrated in the western United States and Burke has sold primarily rubber 
cove base moulding. The Company has developed a well-known brand name 
(BurkeBase) in the western United States by targeting the architectural 
community and installers of commercial flooring. Growth in Flooring Products 
revenues was significant in 1998 due to improvement in the commercial 
construction market in the western United States and the acquisition of 
Mercer.

     The Commercial Products business is comprised of: (i) Purosil brand 
high-performance silicone truck and bus engine hoses; (ii) roofing and other 
fluid barrier membrane products; and (iii) various intermediate and end use 
products based upon Burke's extensive elastomer manufacturing capabilities. 
Revenues generated by silicone hose sales are driven by both new truck and 
bus manufacturing as well as the replacement market. OEM and aftermarket 
customers specify and prefer silicone hoses due to their high performance and 
relatively minor absolute cost. In addition, silicone hoses are increasingly 
being specified on trucks and buses due to the higher performance 
requirements of new engine design. Burke roofing and fluid containment system 
sales have tended to be relatively steady over time. Roofing and fluid 
barrier membranes are used in numerous applications including new and 
replacement commercial roofs and reservoirs. The Hypalon product provides 
significant wear and durability advantages compared with less expensive 
products. Revenues from these products can be materially affected on a 
quarter-to-quarter basis by the size and timing of certain reservoir projects.

</TABLE>

     YEAR ENDED JANUARY 1, 1999 VERSUS YEAR ENDED JANUARY 2, 1998

     NET SALES. Total net sales increased 18.6%, from $90.2 million in 1997 
to $107.0 million in 1998. Aerospace and Defense Products sales grew 8.1%, 
due primarily to increased demand for military products. Flooring Products 
sales increased 75.0%, due primarily to the acquisition of Mercer. Commercial 
Products sales decreased 9.5%, primarily because 1997 included a liner 
project order that favorably affected results for that period, partially 
offset by volume associated with new products introduced during 1998 by the 
silicone hose portion of this product group.

     COST OF SALES. Cost of sales increased 22.5%, from $62.9 million in 1997 
to $77.1 million in 1998. As a percentage of net sales, gross profit 
decreased from 30.3% to 28.0%. The decrease in profit percentage was 
primarily due to temporary operating inefficiencies, both in connection with 
new product ramp-up, and also in connection with the silicone products' 
facility expansion which occurred in July, 1998.

     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and 
administrative expenses increased 18.9%, from $12.2 million in 1997 to $14.5 
million in 1998. The increase in spending was 

                                      18
<PAGE>

primarily due to the acquisition of Mercer. As a percentage of net sales, 
selling, general and administrative expenses remained constant.

     TRANSACTION EXPENSES AND STOCK OPTION PURCHASE. Transaction expenses and 
stock option purchase were one-time expenses associated with the leveraged 
recapitalization in August, 1997.

     AMORTIZATION OF GOODWILL. Amortization of goodwill increased to $1.4 
million in 1998. The increase was due to the acquisition of Mercer.

     INCOME FROM OPERATIONS. As a result of the above factors, income from 
operations increased from a loss of $0.4 million in 1997 to income of $14.0 
million in 1998.

     INTEREST EXPENSE. Interest expense increased 155.5%, from $5.4 million 
in 1997 to $13.8 million in 1998. The increase was due to the issuance of the 
Senior (fixed-rate) Notes on August 20, 1997 and the Floating-Rate Notes on 
April 21, 1998.

     INCOME FROM CONTINUING OPERATIONS. As a result of the above factors, 
income from continuing operations increased from a loss of $3.9 million in 
1997 to income of less than $0.1 million in 1998.

     YEAR ENDED JANUARY 2, 1998 VERSUS YEAR ENDED JANUARY 3, 1997

     NET SALES. Total net sales increased 24.5%, from $72.5 million in 1996 
to $90.2 million in 1997. Aerospace and Defense Products sales grew 26.8%, 
due to strong expansion of commercial aircraft build rates. Despite this 
overall performance, revenue for low-observable materials decreased in the 
second half of the year due to material product design changes by major 
customers, which delayed shipments of these materials. Flooring Products 
sales grew 14.3% due to price increases and generally stronger demand for 
construction products in California and the introduction of vinyl cove base 
products. Commercial Products sales grew 30.1% due to a major sale of 
membrane products for a liner application and due to orders from a new 
customer.

     COST OF SALES. Cost of sales increased 26.6% from $49.7 million in 1996 
to $62.9 million in 1997. The increase was primarily due to the increase in 
net sales over the same period. As a percentage of net sales, gross profit 
decreased from 31.4% in 1996 to 30.3% in 1997. The decrease was due primarily 
to the fact that membrane products, which have a lower gross profit margin 
than the Company's other product lines, constituted a larger portion of total 
net sales in 1997 compared with 1996.

     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and 
administrative expenses increased 5.4%, from $11.6 million in 1996 to $12.2 
million in 1997. The increase included the addition of Flooring and 
Commercial sales personnel. However, as a percentage of net sales, these 
costs declined from 16.0% to 13.6% over the same period.

     TRANSACTION EXPENSES AND STOCK OPTION PURCHASE. Transaction expenses 
were incurred in connection with the Recapitalization. The stock option 
purchase charge in 1997 represents the compensation component of payments 
made for the cancellation of stock options in connection with the 
Recapitalization.

     INCOME FROM OPERATIONS. As a result of the above factors, income from 
operations decreased 103.2%, from $11.2 million in 1996 to a loss of $(0.4) 
million in 1997.

                                      19
<PAGE>

     INTEREST EXPENSE. Interest expense increased 102.7%, from $2.7 million 
in 1996 to $5.4 million in 1997. The increase was due to the issuance of the 
Senior Notes on August 20, 1997.

     INCOME FROM CONTINUING OPERATIONS. As a result of the above factors, 
income from continuing operations decreased 178.3%, from $5.0 million in 1996 
to a loss of $(3.9) million in 1997.

INCOME TAX PROVISION

     For 1998, the Company recorded an income tax provision of $160,000 which 
differed from the federal statutory rate primarily due to filing requirements 
in certain states as a result of the Mercer acquisition.

     For 1996 and 1997, the Company recorded an income tax provision 
(benefit) of 40.8% and (31.6%), respectively, which differs from the federal 
statutory rate primarily due to state income taxes (net of federal benefit) 
and in 1997 due to additional provision for federal and state audits. In 
1996, the Company settled with the Internal Revenue Service ("IRS") certain 
issues relating to the Company's income tax returns for 1988 through 1990. As 
of January 3, 1997, the Company had fully provided for the taxes and interest 
which are payable as a result of the settlement.

     In addition to the above settlement, in 1997, the Company settled with 
the IRS certain issues related to the Company's income tax returns for 1992 
and 1993. The Company fully provided for the taxes and interest which are 
payable as a result of the settlement.

LIQUIDITY AND CAPITAL RESOURCES

     CASH FLOW. The Company's principal uses of cash are to finance working 
capital and capital expenditures related to asset acquisitions and internal 
growth. Burke's net cash provided by operating activities was $6.0 million in 
1998. Excluding the charge related to the stock option purchase, Burke's net 
cash provided by operating activities would have been $5.6 million in 1997.

     CAPITAL REQUIREMENTS. The Company expects to spend approximately $2.5 
million during 1999 on capital expenditures not directly related to 
acquisitions. In 1998, $3.2 million was spent on capital expenditures not 
directly related to acquisitions, including $1.4 million for a replacement 
information technology system that will be completed in 1999. Cash flow from 
operations, to the extent available, may also be used to fund a portion of 
any acquisition expenditures.

     SOURCES OF CAPITAL. On April 21, 1998, the Company acquired all of the 
issued and outstanding capital stock of Mercer, from Sovereign, for an 
aggregate purchase price of $38,474,000 (including acquisition costs of 
$2,280,000).

     Financing for this acquisition and related expenses was provided, in 
large part, from the sale of (the "Offering") $30 million principal amount of 
Floating-Rate Notes Due 2007. The balance of the financing was provided with 
$3.0 million from the sale of 3,000 shares of the Company's 6% Series C 
Cumulative Convertible Preferred Stock (the "Series C Convertible Preferred 
Stock") and cash on hand.

     The Floating-Rate Notes mature on August 15, 2007, with interest on the 
notes payable semi-annually on February 15 and August 15, commencing August 
15, 1998. The Floating-Rate Notes bear interest at a rate per annum equal to 
LIBOR plus 400 basis points, with the interest rate reset semiannually. The 
Floating-Rate Notes are unconditionally guaranteed on a joint and several 
basis by each of the Company's subsidiaries. Upon a change of control of the 
Company, the Company will be 

                                      20
<PAGE>


required to make an offer to repurchase all outstanding Floating-Rate Notes 
at 101% of the aggregate principal amount thereof plus accrued and unpaid 
interest thereon at the date of repurchase.

     Contemporaneously with the Mercer acquisition, the Company amended its 
existing Loan and Security Agreement, as amended from time to time, with 
NationsBank, N.A., as administrative agent, and other lending institutions 
party thereto (the "Credit Agreement") to, among other things, (i) increase 
the Company's borrowing capacity from $15.0 million to $25.0 million (as 
amended, the "Credit Facility"), (ii) add Mercer as a borrowing subsidiary 
(as defined in the Credit Agreement), (iii) increase certain of the baskets 
contained in the restrictive covenants to reflect the increased size of the 
Company after the closing of the Mercer acquisition and (iv) waive any 
default or event of default that may otherwise have resulted from the 
consummation of the Offering and the Mercer acquisition. Following the merger 
of Mercer with and into Burke, which occurred in August 1998, Mercer was no 
longer a borrowing subsidiary under the Credit Agreement.

     The Credit Facility matures in August 2002. Interest on loans under the 
Credit Facility bear interest at rates based upon either, at the Company's 
options, Eurodollar Rates plus a margin of 2.5% or upon the Prime Rate. Loans 
under the Credit Facility are secured by security interests in substantially 
all of the assets of the Company and are guaranteed by any and all current or 
future subsidiaries of the Company, which guarantees are secured by 
substantially all of the assets of such subsidiaries. The Credit Facility 
contains customary covenants restricting the Company's ability to, among 
other things, incur additional indebtedness, create liens or other 
encumbrances, pay dividends or make other restricted payments, make 
investments, loans and guarantees or sell or otherwise dispose of a 
substantial portion of assets to, or merge or consolidate with, another 
entity. The Credit Facility also contains a number of financial covenants 
that will require the Company to meet certain ratios and tests and provide 
that a change of control of the Company (as defined in the Credit Facility) 
will constitute an event of default. At fiscal year end 1998, the Company was 
not in compliance with certain of these covenants. The Company obtained a 
waiver from the bank and future covenants have been amended.

     The Company anticipates that its principal use of cash during 1999 will 
be working capital requirements, debt service requirements and capital 
expenditures. Based upon current and anticipated levels of operations, the 
Company believes that its cash flow from operations, together with amounts 
available under the Credit Facility, will be adequate to meet its anticipated 
requirements for the foreseeable future for working capital, capital 
expenditures and interest payments.

YEAR 2000 ISSUE

     GENERAL DESCRIPTION OF THE YEAR 2000 ISSUE AND THE NATURE AND EFFECTS OF 
THE YEAR 2000 ON INFORMATION TECHNOLOGY (IT) AND NON-IT SYSTEMS

     The Year 2000 issue ("Year 2000 Issue") is the result of computer 
programs being written using two digit rather than four to define the 
applicable year. Any of the Company's computer programs or hardware that have 
date-sensitive software or embedded chips may recognize a date using "00" as 
the year 1900 rather than the Year 2000. This could result in a system 
failure or miscalculation causing disruptions of operations, including, among 
other things, a temporary inability to process transactions, send invoices, 
or engage in similar normal business activities.

     Based on recent assessments, the Company determined that it had to modify
or replace significant portions of its software and certain hardware so that
those systems will properly utilize dates beyond December 31, 1999. The Company
presently believes that with modifications or replacements of existing 

                                      21
<PAGE>

software and certain hardware, the Year 2000 Issue can be mitigated. However, 
if such modifications and replacements are not made, or are not timely 
completed, the Year 2000 Issue could have a material impact on the operations 
of the Company.

     The Company's plan to resolve the Year 2000 Issue involves the following 
three phases: assessment, remediation, and testing. To date, the Company has 
fully completed its assessment of all systems that could be significantly 
affected by the Year 2000 Issue. The completed assessment indicated that most 
of the Company's significant information technology systems could be 
affected, particularly the general ledger, billing, and inventory systems. 
That assessment also indicated that software and hardware (embedded chips) 
used in production and manufacturing systems do not represent significant 
risks. The Company does not believe that the Year 2000 presents a material 
exposure as it relates to the Company's products.

     STATUS OF PROGRESS IN BECOMING YEAR 2000 COMPLIANT

     With respect to its information technology, the Company is 50% complete 
on the remediation phase and expects to complete software and hardware 
replacement no later than June 30, 1999. Completion of the testing phase for 
all significant systems is expected by June 30, 1999.

     The Company is utilizing both internal and external resources to replace 
and test the software and hardware for resolution of the Year 2000 Issue. In 
conjunction with the Company's current $2.2 million information technology 
systems re-engineering effort, approximately 50% of the total cost is 
estimated to be related to the Year 2000 project. Most of the cost of the new 
system will be funded through a lease.

     NATURE AND LEVEL OF IMPORTANCE OF THIRD PARTIES AND THEIR EXPOSURE TO 
THE YEAR 2000 ISSUE

     The Company has no significant systems which would interface directly 
with third party vendors. To date, the Company is not aware of any external 
agent with a Year 2000 Issue that would materially impact the Company's 
results of operations, liquidity, or capital resources. The Company has sent 
out questionnaires to external agents during the first quarter of 1999 in an 
effort to verify the external agents' Year 2000 readiness. However, the 
Company has no means of ensuring that the external agents will be Year 2000 
ready. The inability of external agents to complete their Year 2000 
resolution process in a timely fashion could materially impact the Company. 
The effect of non-compliance by external agents is not determinable.

     RISKS

     Management believes it has an effective program in place to resolve the 
Year 2000 Issue in a timely manner. As noted above, the Company has not yet 
completed all necessary phases of its Year 2000 program. In the event that 
the Company does not complete any additional phases, the Company might be 
unable to take customer orders, manufacture and ship products, invoice 
customers or collect payments. In addition, disruptions in the economy 
generally resulting from the Year 2000 Issue could also materially adversely 
affect the Company. The amount of potential liability and lost revenue cannot 
be reasonably estimated at this time.

     CONTINGENCY PLANS

     The Company currently has no contingency plans in place in the event it 
does not complete all phases of the Year 2000 program. The Company plans to 
evaluate the status of completion in the second quarter of 1999 and determine 
whether such a plan is necessary.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     The Company is exposed to market risks related to fluctuations in 
interest rates on its Senior Notes and Floating-Rate Notes. The Company does 
not currently use interest rate swaps or other types of derivative financial 
instruments.

     For fixed rate debt such as the Senior Notes, changes in interest rates 
generally affect the fair value of the debt instrument. For variable rate 
debt such as the Floating-Rate Notes, changes in interest rates generally do 
not affect the fair value of the debt instrument, but do affect earnings and 
cash flows. The Company does not have an obligation to repay its Senior Notes 
prior to maturity in 2007 and, as a result, interest rate risk and changes in 
fair value should not have a significant impact on the Company. Management 
believes that the interest rate on the Senior Notes approximates the current 
rates available for similar types of financing and as a result the carrying 
amount of the Senior Notes approximates fair value. The carrying value of the 
Floating-Rate Notes approximates fair value as the interest rate is variable 
and resets frequently. The Floating-Rate Notes bear interest at a rate per 
annum equal to LIBOR plus 400 basis points and each one percentage point 
increase in interest rates would result in an increase in interest expense of 
$300,000 per year.

     Management does not believe that the future market rate risk related to 
the Senior Notes and Floating-Rate Notes will have a material impact on the 
Company's financial position, results of operations or liquidity.

                              EMPLOYMENT AGREEMENTS

     In connection with the Recapitalization, the Company entered into 
employment agreements (each, an "Employment Agreement") with two key 
executives. Generally, each Employment Agreement 

                                      29
<PAGE>

provides for the executive's continued employment with the Company in his 
position prior to the execution of the Employment Agreement for a period of 
two years from the date of the Employment Agreement, renewable by mutual 
agreement for successive one-year terms, at an annual salary, bonus and with 
such other employment-related benefits comparable to those received by such 
executive immediately before the execution of the Employment Agreement.

     If the executive is terminated for Cause (as defined in the Employment 
Agreement) or voluntarily terminates his employment prior to the expiration 
of the then-current term, the executive will be entitled to receive unpaid 
compensation through the date of his termination or the date that is 30 days 
after notice of termination is given by the Company, whichever occurs later. 
If the executive's employment is terminated by the Company for any reason 
other than for Cause or the executive dies or is unable to perform his duties 
due to disability for a period of 90 consecutive days, the executive will be 
entitled to receive all compensation that would be due through the end of the 
then-current term, to the extent unpaid on the date of termination.

     Each Employment Agreement contains provisions prohibiting the executive, 
during the period of his employment with the Company and, for two years 
thereafter, from owning, managing, operating, financing, joining or 
controlling, directly or indirectly, any business entity that is, at the time 
of the executive's initial involvement, in competition with the Company in 
any business then or thereafter conducted by the Company. Each Employment 
Agreement also contains provisions requiring the executive to maintain the 
confidentiality of certain information related to the Company during the 
period of his employment with the Company and, under certain circumstances, 
for two years thereafter. Each Employment Agreement further provides that any 
proposals or ideas developed by the executive or that are submitted by the 
executive to the Company during the term of the Employment Agreement, whether 
or not exploited or accepted by the Company, are the property of the Company 
and may not be exploited by the executive except in compliance with the 
Company's policy on conflicts of interest.

                     EXECUTIVE DEFERRED COMPENSATION AGREEMENT

     The Company has established an Executive Deferred Compensation Agreement 
which is a deferred compensation plan for certain executive officers and 
other highly compensated officers of the Company. Commencing on December 1, 
1995 and continuing through the date on which the participant's employment 
with the Company terminates as a result of death, retirement, disability or 
any other cause, the participant is entitled to defer to an account an amount 
set forth in an annual election form, which the participant would otherwise 
be entitled to receive as compensation. Each participant's account accrues 
investment income based upon the investment election of the participant. Such 
deferred amounts are fully vested and are payable upon termination of 
employment, death, retirement or disability. The accumulated amount deferred 
in this plan as of fiscal year end 1998 was $0.5 million.

                               STOCK OPTION PLAN

     The Board of Directors of the Company has adopted the 1997 Stock Option 
Plan (the "Plan"), pursuant to which officers, directors and key employees of 
the Company and its parents and subsidiaries are eligible to receive options 
to purchase the Company's Common Stock. The Plan is administered by the Board 
of Directors. The aggregate number of shares which may be issued under 
options shall not exceed 500,000 shares, subject to adjustment under certain 
circumstances provided for in the Plan. Any stock option granted under the 
Plan may be an Incentive Stock Option (as defined in the Plan) or a 
non-qualified stock option. The price of Incentive Stock Options shall range 
from one hundred to one hundred and ten percent of the fair market value of 
the shares depending upon whether or not the optionee is a ten percent 
holder. The fair market value shall be determined by reference to market 
prices if the stock is publicly traded or shall be determined in good faith 
by the Board in the absence of a public market. Options granted under the 
Plan vest as determined by the Board. No option may be granted under the 
Plan more than ten years from the date of its adoption.

                                401(K) PLANS

     The Company maintains two defined contribution 401(k) plans. The first 
plan covers substantially all of the Company's non-hourly employees who are 
not employed in the Mercer business. The employees become eligible to 
participate after 1,000 hours of service and participants may elect to 
contribute up to 20% of their compensation to this plan, subject to Internal 
Revenue Service limits. The Company matches a portion of the employees' 
contribution. The Company also maintains a defined contribution plan for 
salaried and hourly employees who were formerly employed by Mercer. 
Participating employees contribute to this 401(k) plan based on a percentage 
of their compensation, which is matched by the Company based on a percentage 
of employee contributions.

                            COMPENSATION OF DIRECTORS

     None of the directors who are officers of the Company receives any 
compensation directly for their service on the Company's Board of Directors. 
All other directors receive customary directors' fees for their services. In 
addition, the Company pays Lehman certain fees for various management, 
consulting and financial planning services, including assistance in strategic 
planning, providing market and financial analyses, negotiating and 
structuring financing and exploring expansion opportunities. See "Certain 
Relationships and Related Transactions."

(1)  The address of JFLEI and Messrs. Lehman, Sawyer, Glickman, Oster and Stroud
     is 2001 Jefferson Davis Highway, Suite 607, Arlington, Virginia 22202. The
     address of Jackson National and Mr. Gorchow is 225 West Wacker Drive,
     Chicago, Illinois 60606. The address of MassMutual is 1295 State Street,

     to vote, or to direct the voting of a security, or the sole or shared power
     to dispose, or direct the disposition of, a security.

(3)  Computed based upon the total number of shares of the Company's Common 
     Stock outstanding and the number of shares of the Company's Common Stock 
     underlying the options or warrants held by that person exercisable within 
     60 days of March 15, 1999. In accordance with Rule 13(d)-3 of the Exchange
     Act, any Common Stock that will not be outstanding as of March 15, 1999, 
     which is subject to options or warrants exercisable within 60 days, is 
     deemed to be outstanding for the purpose of computing the percentage of 
     outstanding shares of the Company's Common Stock owned by the person 
     holding such options or warrants, but is not deemed to be outstanding for 
     the purpose of computing the percentage of outstanding shares of the 
     Company's Common Stock owned by any other person. On a fully diluted basis,
     as of March 15, 1999, JFLEI and its affiliates would own approximately
     65% of the Company's Common Stock, the executive officers and directors
     as a group would own approximately 76.5% of the Company's Common Stock 
     and the warrantholders (including Jackson National, MassMutual and 
     Paribas) would have the right to purchase approximately 20% of the 
     Company's Common Stock.

(4)  JFLEI is a Delaware limited partnership managed by Lehman, which is an
     affiliate of the general partner of JFLEI. Each of Messrs. Lehman,
     Glickman, Sawyer, Oster and Stroud, either directly (whether through
     ownership interest or position) or through one or more intermediaries, may
     be deemed to control Lehman and such general partner. Lehman and such
     general partner may be deemed to control the voting and disposition of the
     shares of the Company Common Stock owned by JFLEI. Accordingly, for certain
     purposes, Messrs. Lehman, Glickman, Sawyer, Oster and Stroud may be deemed
     to be beneficial owners of the shares of the Company's Common Stock owned
     by JFLEI.

(5)  Includes the shares beneficially owned by JFLEI, of which Messrs. Lehman,
     Glickman, Sawyer, Oster and Stroud are affiliates.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

MANAGEMENT AGREEMENT

     Pursuant to the terms of the ten-year Management Agreement (the "Management
Agreement") entered into between Lehman and the Company, (i) upon consummation
of the Recapitalization, the Company paid Lehman certain transaction fees and
(ii) the Company agreed to pay Lehman an annual 

                                      31
<PAGE>

management fee equal to $500,000, as may be adjusted from time to time 
subject to necessary board approval, that commenced accruing on October 1, 
1998 and which was to be payable on a quarterly basis in arrears commencing 
on January 1, 1999. During 1998, the Board of Directors approved an amendment 
to the Management Agreement and the Company concurrently entered into a 
Management Services Agreement with Lehman, the combined effect of which was 
to further delineate the management services to be provided by Lehman and to 
provide that Lehman's management fee would be paid in advance on a quarterly 
basis commencing October 1, 1998.

SHAREHOLDERS AGREEMENT

     In connection with the Recapitalization, the Company, JFLEI, the 
Continuing Shareholders (as defined in the Shareholders Agreement) and, in 
their capacity as holders of the Warrants (as defined in the Shareholders 
Agreement), Jackson National Life Insurance Company ("Jackson National"), 
Paribas North America, Inc. ("Paribas"), MassMutual Corporate Value Partners 
Limited, Massachusetts Mutual Life Insurance Company, MassMutual High Yield 
Partners LLC (collectively, "MassMutual") (collectively, the "Shareholders") 
entered into a Shareholders Agreement (the "Shareholders Agreement"), the 
principal terms of which are summarized below:

     CERTAIN VOTING RIGHTS OF HOLDERS OF REDEEMABLE PREFERRED STOCK. If at 
any time after October 15, 2000, any amount of cash dividends payable on the 
Series A and Series B 11 1/2% Cumulative Redeemable Stock (collectively, the 
"Redeemable Preferred Stock"), which was issued on the closing date of the 
Recapitalization, shall have been in arrears and unpaid for four or more 
successive Dividend Payment Dates, then the number of directors constituting 
the Board of Directors shall, without further action, be increased by the 
Dividend Arrears Number (as defined below) and, in addition to any other 
rights to elect directors which the holders of Redeemable Preferred Stock may 
have, the holders of all outstanding shares of Redeemable Preferred Stock, 
voting separately as a class and to the exclusion of the holders of all other 
classes and series of stock of the Company, shall be entitled to elect the 
directors of the Company to fill such newly created directorships.

     If the Company shall fail to redeem shares of Redeemable Preferred Stock 
in accordance with the mandatory redemption provisions described above, then 
the number of directors constituting the Board of Directors shall, without 
further action, be increased by the Control Number (as defined below) and, in 
addition to any other rights to elect directors which the holders of 
Redeemable Preferred Stock may have, the holders of all outstanding shares of 
Redeemable Preferred Stock, voting separately as a class and to the exclusion 
of the holders of all other classes and series of stock of the Company, shall 
be entitled to elect the directors of the Company to fill such newly created 
directorships.

     "Dividend Arrears Number" shall mean such number of additional directors 
of the Company which, when added to the number of directors otherwise 
nominated by the holders of Redeemable Preferred Stock, shall result in the 
number of directors elected by or at the direction of the holders of 
Redeemable Preferred Stock constituting one-third of the members of the Board 
of Directors of the Company.

     "Control Number" shall mean such number of additional directors of the

of the Board of Directors of the Company.


                                      32


<PAGE>

     Any additional directors elected by the Redeemable Preferred Stock 
pursuant to the provisions described above shall remain in office until such 
time as (i) all such dividends in arrears are paid in full or (ii) all shares 
of Redeemable Preferred Stock shall have been redeemed pursuant to the 
mandatory redemption provisions described above, as the case may be.

     RESTRICTIONS ON TRANSFER. The shares of the Company's Common Stock held 
by each of the parties to the Shareholders Agreement, and certain of their 
transferees, are subject to restrictions on transfer. The shares of Common 
Stock may be transferred only to certain related transferees, including, (i) 
in the case of individual Shareholders, family members or their legal 
representatives or guardians, heirs and legatees and trusts, partnerships and 
corporations the sole beneficiaries, partners or shareholders, as the case 
may be, of which are family members, (ii) in the case of partnership 
Shareholders, the partners of such partnership, (iii) in the case of 
corporate Shareholders, affiliates of such corporation and (iv) transferees 
of shares sold in transactions complying with the applicable provisions of 
the Shareholder or Company Right of First Refusal or the Tag-along or 
Drag-Along Rights (as each term is defined below.)

     RIGHTS OF FIRST OFFER. If any Shareholder desires to transfer any shares 
of the Company's Common Stock or Warrants (other than pursuant to certain 
permitted transfers) and if such Shareholder has not received a bona fide 
offer from an unrelated third-party that such shareholder wishes to accept (a 
"Third-Party Offer"), all other Shareholders have a right of first offer (the 
"Right of First Offer") to purchase the shares or warrants (the "Subject 
Shares") upon such terms and subject to such conditions as are set forth in a 
notice (a "First Offer Notice") sent by the selling Shareholder to such other 
Shareholders. If the Shareholders elect to exercise their Rights of First 
Offer with respect to less than all of the Subject Shares, the Company has a 
right to purchase all of the Subject Shares that the Shareholders have not 
elected to purchase. If the Shareholders receiving the First Offer Notice and 
the Company will exercise their respective rights of first offer with respect 
to less than all of the Subject Shares, the selling Shareholder may solicit 
Third-Party Offers to purchase all (but not less than all) of the Subject 
Shares upon such terms and subject to such conditions as are, in the 
aggregate, no less favorable to the selling Shareholder than those set forth 
in the First Offer Notice.

     SUBSCRIPTION OFFER WITH RESPECT TO PRIMARY ISSUANCES. The Company will 
not be permitted to issue equity securities, or securities convertible into 
equity securities to JFLEI or to any of its affiliates unless the Company has 
offered to issue to each of the other Shareholders, on a pro rata basis, an 
opportunity to purchase such securities on the same terms, including price, 
and subject to the same conditions as those applicable to JFLEI and/or its 
affiliate.

     TAG-ALONG RIGHTS. The Shareholders Agreement provides that, if the 
Shareholders and the Company fail to exercise their respective rights of 
first refusal with respect to all of the Subject Shares, the Shareholders 
have the right to "tag along" (the "Tag-Along Right") upon the sale of the 
Company's Common Stock by JFLEI pursuant to a Third-Party Offer.

     DRAG-ALONG RIGHTS. The Shareholders Agreement provides that if one or 
more Shareholders holding a majority of the Company's Common Stock (the 
"Majority Shareholders") propose to sell all of the Common Stock owned by the 
Majority Shareholders, the Majority Shareholders have the right (the 
"Drag-Along Right") to compel the other Shareholders to sell all of the 
shares of Common Stock held by such other Shareholders upon the same terms 
and subject to the same conditions as the terms and conditions applicable to 
the sale by the Majority Shareholders.

                                      33

<PAGE>

     MERGER. The Shareholders Agreement provides that the Company may not 
enter into any merger, consolidation or similar business combination unless 
the terms of such merger provide for all Shareholders to receive the same 
consideration for their shares of Common Stock.

     REGISTERED OFFERINGS. The shares of Common Stock may be transferred in a 
bona fide public offering for cash pursuant to an effective registration 
statement (a "Registered Offering") without compliance with the provisions of 
the Shareholders Agreement related to the Right of First Refusal or the 
Tag-Along or Drag-Along Rights.

     LEGENDS. The shares of Common Stock subject to the Shareholders 
Agreement bear a legend related to the Right of First Refusal and the 
Tag-Along and Drag-Along Rights, which legends will be removed when the 
shares of Common Stock are, pursuant to the terms of the Shareholders 
Agreement, no longer subject to the restrictions on transfer imposed by the 
Shareholders Agreement.

     REGISTRATION RIGHTS. JFLEI and certain other shareholders are entitled 
to one "demand" and unlimited piggyback registration rights, subject to 
additional customary rights and limitations.

     The term of the Shareholders Agreement is the earlier of (i) August 20, 
2007, (ii) the date on which none of the Shareholders nor any of their 
permitted transferees are subject to the terms of the Shareholders Agreement, 
(iii) the date on which none of the shares of Common Stock are subject to the 
restrictions on transfer imposed by the Shareholders Agreement or (iv) the 
consummation of a Registered Offering for an aggregate offering price of 
$25.0 million or more.

INDEMNIFICATION OF OFFICERS AND DIRECTORS

     The Articles of Incorporation of the Company contain provisions 
eliminating the personal liability of directors for monetary damages for 
breaches of their duty of care, except in certain prescribed circumstances. 
The Bylaws of the Company also provide that directors and officers will be 
indemnified to the fullest extent authorized by California law, as it now 
stands or may in the future be amended, against all expenses and liabilities 
reasonably incurred in connection with service for or on behalf of the 
Company. The Bylaws of the Company provide that the rights of directors and 
officers to indemnification is not exclusive of any other right now possessed 
or hereinafter acquired under any statute, agreement or otherwise.

                REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS

The Board of Directors and Shareholders
Burke Industries, Inc. and Subsidiaries

     We have audited the accompanying consolidated balance sheets of Burke
Industries, Inc. and subsidiaries as of January 1, 1999 and January 2, 1998, and
the related consolidated statements of operations, shareholders' equity
(deficit), and cash flows for each of the three fiscal years in the period ended
January 1, 1999. 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 in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

     In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Burke
Industries, Inc. and subsidiaries at January 1, 1999 and January 2, 1998, and
the consolidated results of their operations and their cash flows for each of
the three fiscal years in the period ended January 1, 1999, in conformity with
generally accepted accounting principles.

                                                       /s/   ERNST & YOUNG LLP

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1.   ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

     ORGANIZATION

     Burke Industries, Inc. and subsidiaries (the Company) develop, manufacture,
and market various elastomer products for use in commercial and military
applications. The Company sells its products through a network of distributors
or directly to customers in the construction, defense, and aerospace industries
and other commercial markets, primarily in North America. The Company performs
ongoing credit evaluations of its customers' financial condition and generally
does not require collateral.

     One customer accounted for approximately 10% of net sales in fiscal year
1998, 13% of net sales in fiscal year 1997 and 11% of net sales in fiscal year
1996. No other customers constituted 10% or more of net sales in any of the
three fiscal years ended in 1998.

     Substantially all of the Company's hourly workers in San Jose, California
are represented by the International Association of Machinists and Aerospace
Workers through a collective bargaining agreement that expires October 2, 2000.

     The Company has renewed its collective bargaining agreement with United
Electrical Radio and Machine Workers of America, who represent the Company's
hourly workers in Taunton, Massachusetts through June 5, 2000.

     Burke's employees at the Eustis, Florida location are represented by the
Glass, Molders, Pottery, Plastics and Allied Workers International Union. This
collective bargaining agreement was renegotiated in December 1998 for a three
year term.

     RECAPITALIZATION

     In August 1997, the Company entered into an Agreement and Plan of Merger
(the Merger Agreement) pursuant to which the Company was recapitalized (the
Recapitalization). Pursuant to the Merger Agreement, all shares of the Company's
common stock, other than those retained by certain members of management and
certain other shareholders (Continuing Shareholders), were converted into the
right to receive cash based upon a formula. The Continuing Shareholders agreed
to retain approximately 15% of the common equity of the Company. In order to
finance the transactions contemplated by the Recapitalization, the Company (i)
issued $110 million of senior notes in a debt offering (Note 5); (ii) received
$20 million in cash from an investor group for common stock, and (iii) received
$18 million in cash for the issuance of redeemable preferred stock (the
Transactions). Pursuant to the terms of a ten-year Management Agreement entered
into between the Company and its principal shareholder after completion of the
Recapitalization transaction, the Company paid the shareholder a transaction fee
of $1.0 million and the Company agreed to pay an annual management fee equal to
$500,000 commencing October 1, 1997.

     The Company has four wholly owned subsidiaries, consisting of Burke
Flooring Products, Inc., Burke Rubber Company, Inc., Burke Custom Processing,
Inc., (the Guarantor Subsidiaries) and Burkeline Construction Company, Inc. (the
Non-Guarantor Subsidiary). Each of the Guarantor Subsidiaries' guarantees of the
Company's $110 million senior notes and $30 million floating-rate notes,

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


is full, unconditional and joint and several. The Company's subsidiaries have 
no operations or assets and liabilities and therefore no separate financial 
statements of the Company's subsidiaries are presented.

     In connection with the above August 1997 transactions, the tax benefit the
Company will receive associated with the cost to purchase options issued and
outstanding under the Company's stock option plan, in addition to other tax
savings associated with the transaction, will be distributed to the Company's
continuing and former shareholders when realized by the Company. Accordingly, as
part of the recapitalization the Company recognized a liability of $5,882,000
for the total estimated benefit to be realized of which $953,000 remains at
fiscal year end 1998.

     A lawsuit was filed by a former shareholder against the Company and certain
of its current and former officers and directors. The former shareholder is
asserting various claims in connection with the Company's repurchase of the
former shareholders' shares prior to the Recapitalization. The Company believes
that such claims are without merit and intends to vigorously defend such claims.
Management believes the resolution of this matter will not have a material
adverse effect on the financial position of the Company.

     The Company is subject to various federal, state and local environmental
laws and regulations. The former shareholders of the Company have agreed,
subject to certain limitations, to indemnify the Company against certain
environmental liabilities incurred prior to the Recapitalization. In addition,
the former shareholders of Mercer Products Company, Inc. (Note 2) have agreed,
subject to certain limitations, to indemnify the Company against environmental
liabilities incurred prior to the acquisition of Mercer Products Company, Inc.
Based upon environmental reviews and the indemnification provisions discussed
above, management believes the potential obligations relating to environmental
matters will not have a material adverse effect on the financial position of the
Company.

     ACCOUNTING PERIODS

     The Company's fiscal year ends on the Friday closest to December 31. The
Company maintains a fifty-two/fifty-three week fiscal year cycle, which resulted
in a fifty-three week year in fiscal 1996, a fifty-two week year in fiscal 1997
and a fifty-two week year in fiscal 1998. For convenience, the accompanying
financial statements have been referred to as fiscal years ended 1996, 1997, and
1998 for the periods ended January 3, 1997, January 2, 1998 and January 1, 1999,
respectively.

     CONSOLIDATION

     The accompanying consolidated financial statements include the accounts of
Burke Industries, Inc. and its wholly owned subsidiaries. All significant
intercompany accounts and transactions have been eliminated in consolidation.

     USE OF ESTIMATES

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

<PAGE>

                     BURKE INDUSTRIES, INC. AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


     CASH AND CASH EQUIVALENTS

     Cash and cash equivalents consist of bank demand deposit accounts. At
fiscal year end 1997, restricted cash consisted of a three month U.S. treasury
bill held as security for an outstanding letter of credit.

     REVENUE RECOGNITION

     Revenue from sales of products is generally recognized upon shipment to
customers. For contracts relating to certain products, a portion of the revenue
is recognized upon completion of a part of the manufacturing process and upon
customer acceptance. The remaining revenue is recognized upon completion of the
manufacturing process and shipment.

     WARRANTY

     The Company generally warrants its roofing products for two years, for
which the related costs are not significant. In addition, the Company sells
extended warranties for ten to thirty years. Revenues received for extended
warranties are deferred and amortized over the period in which warranty costs
are expected to be incurred. Warranty reserves and deferred warranty revenues
are included in accrued expenses and other noncurrent liabilities on the
accompanying consolidated balance sheets.

     INVENTORIES

     Inventories are stated at the lower of cost (first-in, first-out method) or
market.

     PROPERTY, PLANT, AND EQUIPMENT

     Property, plant, and equipment are stated at cost. Depreciation is computed
over the estimated useful lives (three to forty years) of the assets using the
straight-line method. Leasehold improvements are amortized by the straight-line
method over the shorter of the estimated useful life of the asset or the term of
the related lease. Amortization of assets under capital leases is included in
depreciation expense.

     FINANCIAL INSTRUMENTS

     The carrying value of accounts receivable and payable and accrued
liabilities approximates fair value due to the short-term maturities of these
assets and liabilities.

     COMPREHENSIVE INCOME

     In June 1997, the Financial Accounting Standards Board (FASB) released
Statement of Financial Accounting Standards No. 130, "Reporting Comprehensive
Income" (FAS 130). FAS 130 establishes standards for the reporting and display
of comprehensive income and its components in a full set of general purpose
financial statements and is effective for fiscal years beginning after December
15, 1997. The adoption of FAS 130 had no impact on the Company's results of
operations or financial position.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


     SEGMENT INFORMATION

     Effective January 1, 1998, the Company adopted the Financial Accounting
Standards Board's Statement of Financial Accounting Standards No. 131,
DISCLOSURES ABOUT SEGMENTS OF AN ENTERPRISE AND RELATED INFORMATION (Statement
131). Statement 131 superseded FASB Statement No. 14, FINANCIAL REPORTING FOR
SEGMENTS OF A BUSINESS ENTERPRISE. Statement 131 establishes standards for the
way that public business enterprises report information about operating segments
in annual financial statements and requires that those enterprises report
selected information about operating segments in interim financial reports.
Statement 131 also establishes standards for related disclosures about products
and services, geographic areas, and major customers. The adoption of Statement
131 did not affect results of operations or financial position, but did affect
the disclosure of segment information.

2.   ACQUISITION OF MERCER PRODUCTS COMPANY, INC.

     On April 21, 1998, the Company acquired all of the issued and outstanding
capital stock of Mercer Products Company, Inc. ("Mercer"), from Sovereign
Specialty Chemicals, Inc., for an aggregate purchase price of $38,474,000
(including acquisition costs of $2,280,000). The acquisition was accounted for
under the purchase method of accounting. The Company's consolidated results of
operations include Mercer's results from the date of acquisition.

     The total purchase price was allocated to the assets acquired and
liabilities assumed based on their estimated fair values as follows:

</TABLE>

     The above purchase price allocation is tentative and subject to change,
although such changes are not anticipated to be significant.

     Financing for the Mercer Acquisition and related expenses was provided, in
large part, from the sale of $30 million principal amount of Floating Interest
Rate Senior Notes Due 2007 (the "Floating-Rate Notes"). The balance of the
financing was provided with $3.0 million from the sale of 3,000 shares of the
Company's 6% Series C Convertible Preferred Stock and cash on hand.

     The following pro forma data was prepared to illustrate the estimated
effect of the Mercer acquisition and the financing related thereto, as if the
Mercer acquisition had occurred as of the beginning of each period presented:

</TABLE>

4.   GOODWILL AND LONG-LIVED ASSETS


     Goodwill represents the excess of the purchase price of acquired companies
over the estimated fair value of the tangible and specifically identified
intangible net assets acquired. In accordance with Statement of Financial
Accounting Standards No. 121 "Accounting for the Impairment of Long-Lived Assets
and for the Long-Lived Assets to Be Disposed Of" (FAS 121), the carrying value
of long-lived assets and related goodwill is reviewed if the facts and
circumstances suggest that they may be impaired. If this review indicates that
the carrying value of these assets will not be recoverable, as determined based
on the undiscounted net cash flows of the entity acquired over the remaining
amortization period, the Company's carrying value is reduced to its estimated
fair value (based on an estimate of discounted future net cash flows).

     Goodwill related to the Mercer acquisition is being amortized on a
straight-line basis over fifteen years. Goodwill related to prior transactions
is being amortized on a straight-line basis over forty years. Accumulated
amortization totaled $1,779,000 and $367,000 at fiscal years ended 1998 and
1997, respectively.

5.   LONG-TERM DEBT AND LEASE OBLIGATIONS

     SENIOR NOTES DUE 2007

     The Senior Notes bear interest at a rate of 10% per annum. Interest on the
Senior Notes is payable semiannually, commencing February 15, 1998. The Senior
Notes mature on August 15, 2007.

     At any time on or before August 15, 2000, the Company may redeem up to 35%
in aggregate principal amount of (i) the initial aggregate principal amount of
the Senior Notes and (ii) the initial principal amount of any additional notes,
on one or more occasions, with the net cash proceeds of one or more public
equity offerings at a redemption price of 110% of the principal amount thereof,
plus accrued and unpaid interest thereon to the redemption date, provided that
at least 65% of the sum of (i) the initial aggregate principal amount of the
Senior Notes and (ii) the initial aggregate principal amount of additional notes
remain outstanding immediately after redemption. The Senior Notes are redeemable
by the Company at stated redemption prices beginning in August 2002.

                                     F-11
<PAGE>

                     BURKE INDUSTRIES, INC. AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


     The Senior Notes are general unsecured obligations of the Company and
senior to all existing and future subordinated indebtedness of the Company. The
obligations of the Company under the bank credit facility are secured by
substantially all of the assets of the Company. Accordingly, such secured
indebtedness ranks senior to the Senior Notes.

     The Senior Notes restrict, among other things, the Company's ability to
incur additional indebtedness, pay dividends or make certain other restricted
payments, incur liens, sell preferred stock of subsidiaries, apply net proceeds
from certain asset sales, merge or consolidate with any other person, sell,
assign, transfer, lease, convey or otherwise dispose of substantially all of the
assets of the Company or enter into certain transactions with affiliates.

     The Company believes the fair value of the Senior Notes at fiscal year end
1998 approximates the carrying value of such indebtedness issued based upon the
incremental borrowing rate for similar types of instruments.

     FLOATING-RATE NOTES

     The Floating-Rate Notes issued in connection with the Mercer acquisition
mature on August 15, 2007, with interest on the notes payable semiannually on
February 15 and August 15, commencing on August 15, 1998. The Floating-Rate
Notes bear interest at a rate per annum equal to LIBOR plus 400 basis points,
with the interest rate set semiannually (9.7% at fiscal year end 1998). The
Floating-Rate Notes are unconditionally guaranteed on a joint and several basis
by each of the Company's subsidiaries. Upon a change of control of the Company,
the Company will be required to make an offer to repurchase all outstanding
Floating-Rate Notes at 101% of the aggregate principal amount thereof plus
accrued and unpaid interest thereon at the date of repurchase.

     The Company believes the fair value of the Floating-Rate Notes at fiscal
year end 1998 approximates the carrying value of such indebtedness as the
interest rate is variable and resets frequently.

     BANK CREDIT FACILITY

     In fiscal year 1998, the Company revised its Loan and Security Agreement
with a bank to provide the Company with a $25.0 million revolving credit
facility expiring August 20, 2002. No amounts are outstanding at fiscal year end
1998 or 1997.

     Indebtedness of the Company under the agreement is secured by a first
priority security interest in substantially all of the Company's assets.

     Indebtedness under the agreement bears interest at a floating rate of
interest equal to, at the Company's option, the eurodollar rate for one, two,
three or six months, plus 2.50% or the bank's prime rate.

     Advances under the agreement are limited to the lesser of (a) $25.0 million
and (b)(i) 85% of eligible accounts receivable plus (ii) 50% of eligible
inventory minus (iii) the aggregate amount of all undrawn letters of credit
issued plus the aggregate amount of any unreimbursed drawings under any
outstanding letters of credit. Letters of credit up to a maximum of $3.0 million
may be issued under the bank credit facility.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


     The credit agreement contains restrictions on the incurrence of debt, the
sale of assets, mergers, acquisitions and other business combinations, voluntary
prepayment of other debt of the Company, transactions with affiliates,
investments, as well as prohibitions on the payment of dividends to, or the
repurchase or redemption of stock from, shareholders, and various financial
covenants, including covenants requiring the maintenance of fixed charge
coverage. At fiscal year end 1998, the Company was not in compliance with
certain of these covenants. On March 16, 1999, the Company obtained a waiver
from the bank and amended future covenants.

6.   REDEEMABLE PREFERRED STOCK

     In connection with the Recapitalization transaction, the Company issued
16,000 shares of redeemable preferred stock designated as Series A 11.5%
Cumulative Redeemable Preferred Stock and 2,000 shares of redeemable preferred
stock designated as Series B 11.5% Cumulative Redeemable Preferred Stock for
cash proceeds of $18 million, less issuance costs of $106,000, less the $2.5
million value assigned to warrants to purchase common shares issued to holders
of preferred stock. The excess of redemption value over the carrying value is
being accreted by periodic charges to retained earnings (accumulated deficit)
through February 2008.

     Dividends will be payable to holders of the redeemable preferred stock, at
the annual rate per share of 11.5% times the sum of $1,000 and accrued but
unpaid dividends. Dividends shall be payable at the annual rate per share of
0.115 shares of redeemable preferred stock through July 15, 2000, and in cash
after July 15, 2000.

     Dividends will be payable quarterly on January 15, April 15, July 15, and
October 15 of each year, commencing October 15, 1997. Dividends shall be fully
cumulative and shall accrue on a quarterly basis.

     If at any time after July 15, 2000, the cash dividends payable on the
redeemable preferred stock shall have been in arrears and unpaid for four or
more successive dividend payment dates, then until the date on which all such
dividends in arrears are paid in full, dividends shall accrue and be payable to
the holders at the annual rate of 13.5% times the sum of $1,000 per share and
accrued but unpaid dividends thereon. Upon payment in full of all dividends in
arrears, cash dividends will thereafter be payable at the 11.5% annual rate set
forth above. There were no dividends in arrears as of fiscal year ended 1998.

     Holders of shares of redeemable preferred stock shall be entitled to
receive the stated liquidation value of $1,000 per share, plus an amount per
share equal to any dividends accrued but unpaid, in the event of any
liquidation, dissolution or winding up of the Company. After payment of the full
amount of the liquidation preference, holders of shares of redeemable preferred
stock will not be entitled to any further participation in any distribution of
assets of the Company.

     The Company may, at its option, redeem at any time, all or any portion of
the shares of the redeemable preferred stock, at a redemption price per share
equal to 100% of the liquidation preference on the date of redemption.

     On February 20, 2008, the Company shall redeem any and all outstanding
shares of redeemable preferred stock, at a redemption price per share equal to
100% of the liquidation preference.

     Upon the occurrence of a change of control (as defined), the redeemable
preferred stock shall be redeemable at the option of the holders, at a
redemption price per share equal to 100% of the liquidation preference.

     The holders of shares of redeemable preferred stock shall not be entitled
to any voting rights. However, without the consent of the holders of at least
two-thirds of the outstanding shares of redeemable

preferred stock, the Company may not change the powers or preferences of the 
redeemable preferred stock, create, authorize or issue any shares of capital 
stock ranking senior or on a parity with the redeemable preferred stock or 
create, authorize or issue any shares of capital stock constituting junior 
securities, unless such junior securities are subordinate in right of payment 
to the redeemable preferred stock.

     If at any time after October 15, 2000, any amount of cash dividends payable
on the Series A Redeemable Preferred Stock shall have been in arrears and unpaid
for four or more successive dividend payment dates, then the holders of the
Series A Redeemable Preferred Stock, shall have the right to elect the smallest
number of directors constituting one-third of the authorized number of
directors, and the holders of the common stock shall have the right to elect the
remaining directors.

     If the Company fails to redeem shares of Series A Redeemable Preferred
Stock in accordance with the mandatory redemption provisions described above,
then the holders of the Series A Redeemable Preferred Stock shall have the right
to elect the smallest number of directors constituting a majority of the
authorized number of directors, and the holders of the common stock shall have
the right to elect the remaining directors.

     The right of the holders of Series A Redeemable Preferred Stock to elect
directors pursuant to the provisions described above shall continue until such
time as all such dividends in arrears are paid in full or all shares of Series A
Redeemable Preferred Stock shall have been redeemed pursuant to the mandatory
redemption provisions.

7.   SHAREHOLDERS' EQUITY

     CONVERTIBLE PREFERRED STOCK

     In connection with the Mercer acquisition, the Company issued $3 million in
Series C Convertible Preferred Stock. The Series C Convertible Preferred Stock
ranks junior to the Redeemable Preferred Stock and when declared, dividends
accrue at an annual rate per share of 6% times the sum of $1,000 and accrued but
unpaid dividends. The holders of Series C Convertible Preferred Stock are
entitled to receive a stated liquidation value of $1,000 per share plus accrued
but unpaid dividends in the event of any liquidation, dissolution or winding up
of the Company. After payment of the liquidation preference, the holders of the
Series C Convertible Preferred Stock are not entitled to further participation
in any distribution of assets of the Company. The holders of Series C
Convertible Preferred Stock are not entitled to any voting rights; however,
without the consent of 51% of the holders of Series C Convertible Preferred
Stock, the Company may not adversely alter the rights and preferences of the
Series C Convertible Preferred Stock.

     Upon the occurrence of a triggering event, the holders of Series C
Convertible Preferred Stock have the option to convert such shares into common
stock at a conversion price of $10 per share, subject to anti-dilution
provisions. A triggering event includes a change of control, an initial public
offering, notice by the Company of an intent to redeem the Convertible Preferred
Stock or the fifth anniversary of the issuance of the Convertible Preferred
Stock.

1996.

     STOCK OPTIONS

     Prior to the Recapitalization, the Company maintained the 1989 Stock Option
Plan and granted nonqualified options not pursuant to a formal plan. In
connection with the Recapitalization, all vested option holders received cash
payment in cancellation of their options totaling $14.1 million and the Company
recorded $14.1 million in compensation expense. All unvested options were
canceled in connection with the Recapitalization.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

     At fiscal year end 1998, options to purchase 92,500 shares of common 
stock are exercisable (1997 - none) and the weighted average remaining 
contractual life is 9 years (1997 - 10 years).

     The Company has elected to follow Accounting Principal Board Opinion No. 
25, "Accounting for Stock Issued to Employees" (APB Opinion No. 25) and 
related Interpretations in accounting for its employee stock options because, 
as discussed below, the alternative fair value accounting provided for under 
the Statement of Financial Accounting Standards No. 123 "Accounting for 
Stock-Based Compensation" (FAS 123), requires use of options valuation models 
that were not developed for use in valuing employee stock options. Under APB 
Opinion No. 25, because the exercise price of the Company's employee stock 
options equals the market price of the underlying stock on the date of grant, 
no compensation expense is recognized.

     Pro forma information regarding net loss has been determined as if the 
Company had accounted for its employee stock options under the fair value 
method of FAS 123. The fair value for all options granted was estimated at 
the date of grant using the minimum value options pricing model with the 
following weighted average assumptions: a risk-free interest rate of 5.50%; 
no dividend yield; and a weighted average expected life of the option of five 
years. The weighted average fair value of these options granted was $2.40 per 
share for 1998.

     The Minimum Value option valuation method may be used by companies 
without publicly traded equity to value an award. Option valuation models 
require the input of highly subjective assumptions, including expected stock 
price volatility. Because the Company's employee stock options have 
characteristics significantly different from those of traded options and 
because changes in the subjective input assumptions can materially affect the 
fair value estimate, in management's opinion, the existing models do not 
necessarily provide a reliable single measure of the fair value of its 
employee stock options.

     Had compensation costs for the Company's stock option plan been 
determined on the fair value at the grant dates for awards under the plan 
consistent with the method of FAS 123, the Company's pro forma net loss would 
have been $64,000 for the fiscal year end 1998.

     The effect of applying the FAS 123 minimum value method to the stock 
options granted in fiscal years ended 1997 and 1996 would not result in pro 
forma (loss) income materially different from historical amounts reported. 
Therefore, such pro forma information and weighted average assumptions 
specified in FAS 123 are not separately presented herein for fiscal year end 
1996 and 1997. Future pro forma net income results may be materially 
different from actual amounts reported.

     WARRANTS

     Warrants to purchase 964,000 shares of common stock of the Company at 
the initial exercise price of $4.67 per share were issued to the holders of 
the preferred stock. The warrants are immediately exercisable until February 
20, 2008. The exercise price and number of Warrant Shares are both subject to 
adjustment in certain events.

8.   DISCONTINUED OPERATION

     On June 28, 1996, the Company disposed of certain of the assets related 
to its custom-molded organic rubber products manufacturing operation for cash 
and future consideration. The assets were sold to a newly formed corporation 
that is not related to the Company.

     The 1996 loss from the discontinued operation includes results through 
June 28, 1996. Net sales of the discontinued operation were $4,279,000 in 
1996.

9.   PENSION AND RETIREMENT PLANS

     The Company maintains a defined benefit pension plan covering 
substantially all of its hourly employees in San Jose, California. The 
benefits are based on years of service and the benefit credit rates stated in 
the provisions of the plan. The Company funds the plan at the minimum amount 
required to be paid under the provisions of the Employee Retirement and 
Income Security Act of 1976 (ERISA). Contributions are intended to provide 
for benefits attributed to service to date as well as for those expected to 
be earned in the future.

     The following tables set forth the plan's funded status and amounts 
recognized in the Company's consolidated balance sheets at fiscal year end:

     The Company also maintains a defined contribution 401(k) plan covering 
substantially all of its other regular employees. The employees become 
eligible for participation after 1,000 hours of service. Participants may 
elect to contribute up to 20% of their compensation to this plan, subject to 
Internal Revenue Service (IRS) limits. The Company matches a portion of the 
employees' contribution. The Company contributed approximately $164,000, 
$156,000, and $113,000, to this plan in 1998, 1997, and 1996, respectively.

     The Company also sponsors a defined contribution 401(k) plan for the 
employees in the Mercer business. Participation in this plan is available to 
all salaried and hourly employees of the Company who work in the Mercer 
business. Participating employees contribute to the 401(k) plan based on a 
percentage of their compensation which is matched, based on a percentage of 
employee contributions, by the Company. The Company contributed approximately 
$93,000 to the plan subsequent to the Mercer acquisition in 1998.

     The Company also has a deferred compensation program for certain 
officers and employees. Such deferred amounts are fully vested and are 
payable upon termination of employment, death or retirement. Each 
participant's account accrues investment income based upon the investment 
election of the participant. The accumulated amount deferred as of fiscal 
year end 1998 is $532,000 (1997 - $296,000).

11.  SEGMENT INFORMATION

     The Company has two reportable segments: organic products and silicone 
products. The organic products group produces and distributes rubber and 
vinyl wall base, other floor covering accessory products, flexible membranes 
and other organic rubber products. The silicone products group produces and 
distributes precision silicone seals and other products used on commercial 
and military aircraft as well as high performance silicone truck and bus 
engine hoses and other silicone rubber products.

     The Company evaluates performance and allocates resources based on the 
operating income or loss before taxes, interest, corporate general and 
administrative expenses and amortization expense related to goodwill from the 
Mercer Acquisition. The accounting policies of the reportable segments are 
the same as those described in the summary of significant accounting 
policies. There are no intersegment sales or transfers.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


     The Company's reportable segments are business units that offer 
different products. The reportable segments are each managed separately 
because they manufacture and distribute distinct products with different 
production processes.

($3,258,000 + $358,000);

                  WHEREAS, pursuant to Sections 2(c) and 2(g) of the 
Agreement, the parties used the estimated $3,500,000 Working Capital Target 
as a benchmark to establish the Net Working Capital adjustment thresholds at 
$3,400,000 to $3,600,000, representing $100,000 above and $100,000 below the 
estimated Working Capital Target of $3,500,000 (the average of $3,776,000 and 
$3,258,000);

                  WHEREAS, the parties now desire to amend the Agreement to 
make the Working Capital Target equal to $3,700,000, reflecting the rounded 
average of Mercer's Net

Working Capital of $3,776,000 at September 30, 1997 and Mercer's Net Working 
Capital of $3,616,000 at December 31, 1997;

                  WHEREAS, the parties also desire to amend Sections 2(c) and 
2(g) of the Agreement to establish the Net Working Capital thresholds at 
$3,600,000 to $3,800,000, representing $100,000 above and $100,000 below the 
amended estimated Working Capital Target of $3,700,000;

                  WHEREAS, Section 8(b)(i) of the Agreement presently 
provides, in part, that Seller will be obligated to indemnify Buyer from and 
against all aggregate losses in excess of $25,000 resulting from any breach 
of any representation or warranty of Seller contained in Section 4 of the 
Agreement that causes Buyer to suffer aggregate losses in excess of a 
$250,000 threshold;

                  WHEREAS, the parties now desire to amend Section 8(b)(i) of 
the Agreement to provide that Seller will be obligated to indemnify Buyer 
from and against all aggregate losses in excess of $100,000 resulting from 
any such breach;

                  WHEREAS, the parties desire to amend the Agreement to add a 
new Section 8(b)(vii) to the Agreement pursuant to which Seller will 
indemnify Buyer, its successors, and successors in interest, from and against 
the entirety of any Adverse Consequences the Buyer, its successors, and 
successors in interest may suffer resulting from, arising out of, or relating 
to liability attributable to any and all claims made by Mrs. Sukie George 
against Mercer or any of its affiliates relating to, among other things, 
alleged employment discrimination and retaliation by Mercer or any of its 
affiliates prior to the Closing Date; and

                  WHEREAS, the parties desire to amend Section 8(c) of the 
Agreement to add a new sentence at the end of Section 8(c) pursuant to which 
Buyer will indemnify Seller, its successors, and successors in interest, from 
and against the entirety of any Adverse Consequences the Seller, its 
successors, and successors in interest may suffer resulting from, arising out 
of, or relating to liability attributable to any and all claims by RTC 
Properties, Inc. against the Seller in relation to the additional security 
deposit of $25,000 which Seller will provide in connection with the 
assignment of that certain lease between RTC Properties, Inc. and Mercer 
Products Co., Inc., dated December 1, 1988, as amended by the Fourth

                  NOW, THEREFORE, BE IT RESOLVED, that in consideration of 
the premises herein contained and for other good and valuable consideration, 
the receipt and sufficiency of which are hereby acknowledged, the parties

the Buyer, its successors, and successors in interest, from and against the

2.   PREMISES.

     2.1  LETTING.  Lessor hereby leases to Lessee, and Lessee hereby leases
from Lessor, the Premises, for the term, at the rental, and upon all of the
terms, covenants and conditions set forth in this Lease.  Unless otherwise
provided herein, any statement of size set forth in this Lease, or that may have
been used in 

<PAGE>

calculating rental, is an approximation which the Parties agree is reasonable 
and the rental based thereon is not subject to revision whether or not the 
actual size is more or less.

     2.2  CONDITION.  Lessor shall deliver the Premises broom clean and free of
debris on the Commencement Date or the Early Possession Date, whichever first
occurs ("START DATE"), and warrants that the existing electrical, plumbing, fire
sprinkler system, lighting, heating, ventilating and air conditioning systems
("HVAC"), loading doors, if any, and all other such elements of the building, in
the Premises, other than those constructed by Lessee, shall be in good operating
condition on said date and that the surface and structural elements of the roof,
bearing walls and foundation of any buildings on the Premises (the "BUILDING")
shall be free of material defects.  If a non-compliance with said warranty
exists as of the Start Date, Lessor shall, except as otherwise provided in this
Lease, promptly after receipt of written notice from Lessee setting forth with
specificity the nature and extent of such non-compliance, rectify same at
Lessor's expense.  If, after the Start Date, Lessee does not give Lessor written
notice of any non-compliance with this warranty within (i) six (6) months as to
the HVAC systems or (ii) thirty (30) days as to the remaining systems and other
elements of the Building, correction of such non-compliance shall be the
obligation of Lessee at Lessee's sole cost and expense, except for the roof,
foundations, and bearing walls which are handled as provided in paragraph 7.

     2.3  COMPLIANCE.  Lessor warrants that the improvements on the Premises
comply with all applicable laws, covenants or restrictions of record, building
codes, regulations and ordinances ("APPLICABLE REQUIREMENTS") in effect on the
Start Date.  Said warranty does not apply to the use to which Lessee will put
the Premises or to any Alterations or Utility Installations (as defined in
Paragraph 7.3(a)) made or to be made by Lessee.  NOTE:  Lessee is responsible
for determining whether or not the zoning is appropriate for Lessee's intended
use, and acknowledges that past uses of the Premises may no longer be allowed. 
If the Premises do not comply with said warranty, Lessor shall, except as
otherwise provided, promptly after receipt of written notice from Lessee setting
forth with specificity the nature and extent of such non-compliance, rectify the
same at Lessor's expense.  If Lessee does not give Lessor written notice of a
non-compliance with this warranty within six (6) months following the Start
Date, correction of that non-compliance shall be the obligation of Lessee at
Lessee's sole cost and expense.  If the Applicable Requirements are hereafter
changed (as opposed to being in existence at the Start Date, which is addressed
in Paragraph 6.2(e) below) so as to require during the term of this Lease the
construction of an addition to or an alteration of the Building, the remediation
of any Hazardous Substance, or the reinforcement or other physical modification
of the Building ("CAPITAL EXPENDITURE"), Lessor and Lessee shall allocate the
cost of such work as follows:

          (a)  Subject to Paragraph 2.3(c) below, if such Capital Expenditures
are required as a result of the specific and unique use of the Premises by
Lessee as compared with uses by tenants in general, Lessee shall be fully
responsible for the cost thereof, provided, however that if such Capital
Expenditure is required during the last two (2) years of this Lease and the cost
thereof exceeds six (6) months' Base Rent, Lessee may instead terminate this
Lease unless Lessor notifies Lessee, in writing, within ten (10) days after
receipt of Lessee's termination notice that Lessor has elected to pay the
difference between the actual cost hereof and the amount equal to six (6)
months' Base Rent.  If Lessee elects termination, Lessee shall immediately cease
the use of the Premises which requires such Capital Expenditure and deliver to
Lessor written notice specifying a termination date at least ninety (90) days
thereafter.  Such termination date shall, however, in no event be earlier than
the last day that Lessee could legally utilize the Premises without commencing
such Capital Expenditure.

          (b)  If such Capital Expenditure is not the result of the specific and
unique use of the Premises by Lessee (such as, governmentally mandated seismic
modifications), then Lessor and Lessee shall allocate the obligation to pay for
such costs pursuant to the provisions of Paragraph 7.1(c); provided, however,
that if such Capital Expenditure is required during the last two years of this
Lease or if Lessor reasonably determines that it is not economically feasible to
pay its share thereof, Lessor shall have the option to terminate this Lease upon
ninety (90) days prior written notice to Lessee unless Lessee notifies Lessor,
in writing, within ten (10) days after receipt of Lessor's termination notice
that Lessee will pay for such Capital Expenditure.  If Lessor does not elect to
terminate, and fails to tender its share of any Capital Expenditure, Lessee may
advance such funds and deduct same, with interest from Rent until Lessor's share
of such costs have been fully paid.  If Lessee is unable to finance Lessor's
share, or if the balance of the Rent due and payable for the remainder of this
Lease is not sufficient to fully reimburse Lessee on an offset basis, Lessee
shall have the right to terminate this Lease upon thirty (30) days written
notice to Lessor.

          (c)  Notwithstanding the above, the provisions concerning Capital
Expenditures are intended to apply only to non-voluntary, unexpected, and new
Applicable Requirements.  If the Capital Expenditures are instead triggered by
Lessee as a result of an actual or proposed change in use, change in intensity
of use, or modification of the Premises then, and in that event, Lessee shall be
fully responsible for the cost thereof, and Lessee shall not have any right to
terminate this Lease.

                                      2
<PAGE>

     2.4  ACKNOWLEDGMENTS.  Lessee acknowledges that:  (a) it has been 
advised by the Lessor and/or Brokers to satisfy itself with respect to the 
condition of the Premises (including but not limited to the electrical, HVAC 
and fire sprinkler systems, security, environmental aspects, and compliance 
with Applicable Requirements) and their suitability for Lessee's intended 
use; (b) Lessee has made such investigation as it deems necessary with 
reference to such matters and assumes all responsibility therefor as the same 
relate to its occupancy of the Premises; and (c) neither Lessor, Lessor's 
agents, nor any Broker has made any oral or written representations or 
warranties with respect to the said matters other than as set forth in this 
Lease.  In addition, Lessor acknowledges that:  (a) Broker has made no 
representations, promises or warranties concerning Lessee's ability to honor 
the Lease or suitability to occupy the Premises; and (b) it is Lessor's sole 
responsibility to investigate the financial capability and/or suitability of 
all proposed tenants.

     2.5  LESSEE AS PRIOR OWNER/OCCUPANT.  The warranties made by Lessor in 
this Paragraph 2 shall be of no force or effect if immediately prior to the 
Start Date Lessee was the owner or occupant of the Premises.  In such event, 
Lessee shall be responsibly for any necessary corrective work. 

3.   TERM.

     3.1  TERM.  The Commencement Date, Expiration Date and Original Term of 
this Lease are as specified in Paragraph 1.3.

     3.2  EARLY POSSESSION.  If Lessee totally or partially occupies the 
Premises prior to the Commencement Date, the obligation to pay Base Rent 
shall be abated for the period of such early possession.  All other terms of 
this Lease shall, however be in effect during such period.  Any such early 
possession shall not affect the Expiration Date.

     3.3  DELAY IN POSSESSION.  Lessor agrees to use its best commercially 
reasonable efforts to deliver possession of the Premises to Lessee by the 
Commencement Date.  If, despite said efforts, Lessor is unable to deliver 
possession as agreed, Lessor shall not be subject to any liability therefor, 
nor shall such failure affect the validity of this Lease.  Lessee shall not, 
however, be obligated to pay Rent or perform any other obligation until it 
receives possession of the Premises.  If possession is not delivered within 
sixty (60) days after the Commencement Date, Lessee may, at its option, by 
notice in writing within ten (10) days after the end of such sixty (60) day 
period, cancel this Lease, in which event the Parties shall be discharged 
from all obligations hereunder.  If such written notice is not received by 
Lessor within said ten (10) day period, Lessee's right to cancel shall 
terminate. Except as otherwise provided, if possession is not tendered to 
Lessee by the Start Date and Lessee does not terminate this Lease, as 
aforesaid, any period of rent abatement that Lessee would otherwise have 
enjoyed shall run from the date of delivery of possession and continue for a 
period equal to what Lessee would otherwise have enjoyed under the terms 
hereof, but minus any days of delay caused by the acts, changes or omissions 
of Lessee.  If possession of the Premises is not delivered within four (4) 
months after the Commencement Date, this Lease shall terminate unless other 
agreements are reached between Lessor and Lessee in writing.

     3.4  LESSEE COMPLIANCE.  Lessor shall not be required to tender 
possession of the Premises to Lessee until Lessee complies with its 
obligation to provide evidence of insurance (Paragraph 8.5).  Pending 
delivery of such evidence, Lessee shall be required to perform all of its 
obligations under this Lease from and after the Start Date, including the 
payment of Rent, notwithstanding Lessor's election to withhold procession 
pending receipt of such evidence of insurance.  Further, if Lessee is 
required to perform any other conditions prior to or concurrent with the 
Start Date, the Start Date shall occur but Lessor may elect to withhold 
possession until such conditions are satisfied.

4.   RENT.

     4.1  RENT DEFINED.  All monetary obligations of Lessee to Lessor under 
the terms of this Lease (except for the Security Deposit) are deemed to be 
rent ("Rent").

     4.2  PAYMENT.  Lessee shall cause payment of Rent to be received by 
Lessor in lawful money of the United States, without offset or deduction 
(except as specifically permitted in this Lease), on or before the day on 
which it is due. Rent for any period during the term hereof which is for less 
than one (1) full calendar month shall be prorated based upon the actual 
number of days of said month.  Payment of Rent shall be made to Lessor at its 
address stated herein or to such other persons or place as Lessor may from 
time to time designate in writing.  Acceptance of a payment which is less 
than the amount then due shall not be a waiver of Lessor's rights to the 
balance of such Rent, regardless of Lessor's endorsement of any check so 
stating.

5.   SECURITY DEPOSIT.  Lessee shall deposit with Lessor upon execution 
hereof the Security Deposit as security for Lessee's faithful performance of 
its obligations under this Lease.  If Lessee fails to pay Rent or 

                                      3
<PAGE>


otherwise Defaults under this Lease, Lessor may use, apply or retain all or 
any portion of said Security Deposit for the payment of any amount due Lessor 
or to reimburse or compensate Lessor for any liability, expense, loss or 
damage which Lessor may suffer or incur by reason thereof.  If Lessor uses or 
applies all or any portion of said Security Deposit, Lessee shall within ten 
(10) days after written request therefor deposit monies with Lessor 
sufficient to restore said Security Deposit to the full amount required by 
this Lease.  If the Base Rent increases during the term of this Lease, Lessee 
shall, upon written request from Lessor, deposit additional monies with 
Lessor so that the total amount of the Security Deposit shall at all times 
bear the same proportion to the increase Base Rent as the initial Security 
Deposit bore to the initial Base Rent.  Should the Agreed Use be amended to 
accommodate a material change in the business of Lessee or to accommodate a 
sublessee or assignee, Lessor shall have the right to increase the Security 
Deposit to the extent necessary, in Lessor's reasonable judgment, to account 
for any increased wear and tear that the Premises may suffer as a result 
thereof.  If a change in control of Lessee occurs during this Lease and 
following such change the financial condition of Lessee is, in Lessor's 
reasonable judgment, significantly reduced, Lessee shall deposit such 
additional monies with Lessor as shall be sufficient to cause the Security 
Deposit to be at a commercially reasonable level based on said change in 
financial condition. Lessor shall not be required to keep the Security 
Deposit separate from its general accounts.  Within fourteen (14) days after 
the expiration or termination of this Lease, if Lessor elects to apply the 
Security Deposit only to unpaid Rent, and otherwise within thirty (30) days 
after the Premises have been vacated pursuant to Paragraph 7.4(c) below, 
Lessor shall return that portion of the Security Deposit not used or applied 
by Lessor.  No part of the Security Deposit shall be considered to be held in 
trust, to bear interest or to be prepayment for any monies to be paid by 
Lessee under this Lease.

6.   USE.

     6.1  USE.  Lessee shall use and occupy the Premises only for the Agreed 
Use, or any other legal use which is reasonably comparable thereto, and for 
no other purpose.  Lessee shall not use or permit the use of the Premises in 
a manner that is unlawful, creates damage, waste or a nuisance, or that 
disturbs owners and/or occupants of, or causes damage to neighboring 
properties.  Lessor shall not unreasonably withhold or delay its consent to 
any written request for a modification of the Agreed Use, so long as the same 
will not impair the structural integrity of the improvements on the Premises 
or the mechanical or electrical systems therein, or is not significantly more 
burdensome to the Premises. If Lessor elects to withhold consent, Lessor 
shall within five (5) business days after such request give written 
notification of same, which notice shall include an explanation of Lessor's 
reasonable objections to the change in use.

     6.2  HAZARDOUS SUBSTANCES.  See Addendum Paragraph 9.

          (a)  REPORTABLE USES REQUIRE CONSENT.  The term "HAZARDOUS SUBSTANCE"
as used in this Lease shall mean any product, 

     6.3  LESSEE'S COMPLIANCE WITH APPLICABLE REQUIREMENTS.  Except as otherwise
provided in this Lease, Lessee shall, at Lessee's sole expense, fully,
diligently and in a timely manner, materially comply with all Applicable
Requirements, the requirements of any applicable fire insurance underwriter or
rating bureau, and the reasonable recommendations of Lessor's engineers and/or
consultants which relate in any manner to the Premises, without regard to
whether said requirements are not in effect or become effective after the Start
Date.  Lessee shall, within ten (10) days after receipt of Lessor's written
request, provide Lessor with copies of all permits and other documents, and
other information evidencing Lessee's compliance with any Applicable
Requirements specified by Lessor, and shall immediately upon receipt, notify
Lessor in writing (with copies of any documents involved) of any threatened or
actual claim, notice, citation, warning, complaint or report pertaining to or
involving failure by Lessee or the Premises to  comply with any Applicable
Requirements.

     6.4  INSPECTION; COMPLIANCE.  Lessor and Lessor's "Lender" (as defined in
Paragraph 30 below) and consultants shall have the right to enter into Premises
at any time, in the case of an emergency, and otherwise at reasonable times, for
the purpose of inspecting the condition of the Premises and for verifying
compliance by Lessee with this Lease.  The cost of any such inspections shall be
paid by Lessor, unless a violation of Applicable Requirements, or a
contamination is found to exist or be imminent, or the inspection is requested
or ordered by a governmental authority.  In any such case, Lessee shall upon
request reimburse Lessor for the cost of such inspections, so long as such
inspection is reasonably related to the violation or contamination.

7.   MAINTENANCE; REPAIRS; UTILITY INSTALLATIONS; TRADE FIXTURES AND
ALTERATIONS.

     7.1  LESSEE'S OBLIGATIONS.

          (a)  IN GENERAL.  Subject to the provisions of Paragraphs 2.2
(Condition), 2.3 (Compliance  with Covenants, Restrictions and Building Code),
6.3 (Lessee's Compliance with Applicable Requirements), 7.2 (Lessor's
Obligations), 9 (Damage and Destruction), and 14 (Condemnation), Lessee shall,
at Lessee's sole 

                                      4
<PAGE>


expense, keep the Premises, Utility Installations, and Alterations in good 
order, condition and repair (whether or not the portion of the Premises 
requiring repairs, or the means of repairing the same, are reasonably or 
readily accessible to Lessee, and whether or not the need for such repairs 
occurs as a result of Lessee's use, any prior use, the elements or the age of 
such portion of the Premises), including, but not limited to, all equipment 
or facilities, such as plumbing, heating, ventilating, air conditioning, 
ventilating, electrical, lighting facilities, boilers, pressure vessels, fire 
protection system, fixtures, walls (interior and exterior), ceilings, roofs, 
floors, windows, doors, skylights, landscaping, driveways, parking lots, 
fences, signs, sidewalks and parkways located in, on, or adjacent to the 
Premises.  Lessee is also responsible for keeping the roof and roof drainage 
clean and free of debris.  Lessor shall keep the surface and structural 
elements of the roof, foundations and bearing walls in good repair (see 
paragraph 7.2).  Lessee, in keeping the Premises in good order, condition and 
repair, shall exercise and perform good maintenance practices.  Lessee's 
obligations shall include restorations, replacements or renewals when 
necessary to keep the Premises and all improvements thereon or a part thereof 
in good order, condition and state of repair.  Lessee shall, during the term 
of this Lease, keep the exterior appearance of the Building in a first-class 
condition (including, e.g., graffiti removal) consistent with the exterior 
appearance of other similar facilities of comparable age and size in the 
vicinity, including, when necessary, the exterior repainting of the Building. 
Lessee will not be required to paint the building exterior more frequently 
than every five (5) years.

          (b)  SERVICE CONTRACTS.  Lessee shall, at Lessee's sole expense,
procure and maintain contracts, with copies to Lessor, in customary form and
substance for, and with contractors specializing and experienced in the
maintenance of the following equipment and improvements ("Basic Elements"), if
any, if and when installed on the Premises:  (i) HVAC equipment, (ii) boiler and
pressure vessels, (iii) fire extinguishing systems, including the fire alarm
and/or smoke detection, (iv) landscaping and irrigation systems, (v) driveways
and parking lots, (vi) clarifiers, (vii) basic utility feed to the perimeter of
the Building, and (viii) any other equipment, if reasonably required by Lessor.

          (c)  REPLACEMENT.  Subject to Lessee's indemnification of Lessor as
set forth in Paragraph 8.7 below, and without relieving Lessee of liability
resulting from Lessee's failure to exercise and perform good maintenance
practices, if the Basic Elements described in Paragraph 7.1(b) cannot be
repaired other than at a cost which is in excess of 50% of the cost of replacing
such Basic Elements, then such Basic Elements shall be replaced by lessor, and
the cost thereof shall be prorated between the Parties and Lessee shall only be
obligated to pay, each month during the remainder of the term of this Lease, on
the date on which Base Rent is due, an amount equal to the product of
multiplying the cost of such replacement by a fraction, the numerator of which
is one, and the denominator of which is the number of months of the useful life
of such replacement as such useful life is specified pursuant to Federal income
tax regulations or guidelines for depreciation thereof (including interest on
the unamortized balance as is then commercially reasonable in the judgment of
Lessor's accountants), with Lessee reserving the right to repay its obligation
at any time.

     7.2  LESSOR'S OBLIGATIONS.  Subject to the provisions of Paragraphs 2.2 
(Condition), 2.3 (Compliance  with Covenants, Restrictions and Building Code), 9
(Damage or Destruction), and 14 (Condemnation), it is intended by the Parties
hereto that Lessor have no obligation, in any manner whatsoever, to repair and
maintain the Premises, or the equipment therein, all of which obligations are
intended to be that of the Lessee, except for the surface and structural
elements of the roof, foundation and bearing walls, the repair of which shall be
the responsibility of Lessor upon receipt of notice that such a repair is
necessary.  It is the intention of the Parties that the terms of this Lease
govern the respective obligations of the Parties as to maintenance and repair of
the Premises, and they expressly waive the benefit of any statute now or
hereafter in effect to the extent it is inconsistent with the terms of this
Lease.

     7.3  UTILITY INSTALLATIONS; TRADE FIXTURES; ALTERATIONS WHICH COST MORE
THAN $25,000.

          (a)  DEFINITIONS; CONSENT REQUIRED.  The term "UTILITY INSTALLATIONS"
refers to all floor and window coverings, air lines, power panels, electrical
distribution, security and fire protection systems, communication systems,
lighting fixtures, HVAC equipment, plumbing, and fencing in or on the Premises. 
The term "TRADE FIXTURES" shall mean Lessee's machinery and equipment that can
be removed without doing material damage to the Premises.  The term
"ALTERATIONS" shall mean any modification of the improvements, other than
Utility Installations or Trade Fixtures, whether by addition or deletion. 
"LESSEE OWNED ALTERATIONS AND/OR UTILITY INSTALLATIONS" are defined as
Alterations and/or Utility Installations made by lessee that are not yet owned
by Lessor pursuant to Paragraph 7.4(a).  Lessee shall not make any Alterations
or Utility Installations to the Premises without Lessor's prior written consent.
Lessee may, however, make non-structural Utility Installations to the interior
of the Premises (excluding the roof) without such consent but upon notice to
Lessor, as long as they are not visible from the outside, do not involve
puncturing, relocating or removing the roof or any existing walls, and the
cumulative cost thereof during this Lease as extended does not exceed $150,000
in the aggregate or $25,000 per utility installation in any one year.

                                      5
<PAGE>

          (b)  CONSENT.  Any Alterations or Utility Installations that Lessee 
shall desire to make and which require the consent of the Lessor shall be 
presented to Lessor in written form with detailed plan.  Consent shall be 
deemed conditioned upon Lessee's:  (i) acquiring all applicable governmental 
permits, (ii) furnishing Lessor with copies of such permits and the plans and 
specifications prior to commencement of the work, and (iii) compliance with 
all conditions of said permits and other Applicable Requirements in a prompt 
and expeditious manner.  Any Alterations or Utility Installations shall be 
performed in a workmanlike manner with good and sufficient materials.  Lessee 
shall promptly upon completion furnish Lessor with as-built plans and 
specifications. For work which costs an amount equal to the greater of one 
month's Base Rent, or $25,000, Lessor may condition its consent upon Lessee 
providing a lien and completion bond in an amount equal to one and one-half 
times the estimated cost of such Alteration or Utility Installation and/or 
upon Lessee's posting an additional Security Deposit with Lessor.

          (c)  INDEMNIFICATION.  Lessee shall pay, when due, all claims for 
labor or materials furnished or alleged to have been furnished to or for 
Lessee at or for use on the Premises, which claims are or may be secured by 
any mechanics' or materialmen's lien against the Premises or any interest 
therein. Lessee shall give Lessor not less than ten (10) days' notice prior 
to the commencement of any work in, on or about the Premises, and Lessor 
shall have the right to post notices of non-responsibility.  If Lessee shall 
contest the validity of any such lien, claim or demand, then Lessee shall, at 
its sole expense defend and protect itself, Lessor and the Premises against 
the same and shall pay and satisfy any such adverse judgment that may be 
rendered thereon before the enforcement thereof.  If Lessor shall require, 
Lessee shall furnish a surety bond in an amount equal to one and one-half 
times the amount of such contested lien, claim or demand, indemnifying Lessor 
against liability for the same.  If Lessor elects to participate in any such 
action, Lessee shall pay Lessor's attorneys' fees and costs.

     7.4  OWNERSHIP; REMOVAL; SURRENDER, AND RESTORATION.

          (a)  OWNERSHIP.  Subject to Lessor's right to require removal or 
elect ownership as hereinafter provided, all Alterations and Utility 
Installations made by Lessee shall be the property of Lessee, but considered 
a part of the Premises.  Lessor may, at any time, elect in writing to be the 
owner of all or any specified part of the Lessee Owned Alterations and 
Utility Installations. Unless otherwise instructed per subparagraph 7.4(b) 
hereof, all Lessee Owned Alterations and Utility Installations shall, at the 
expiration or termination of this Lease, become the property of Lessor and be 
surrendered by Lessee with the Premises.

          (b)  REMOVAL.  By delivery to Lessee of written notice from Lessor 
not earlier than ninety (90) and not later than thirty (30) days prior to the 
end of the term of this Lease, Lessor may require that any or all Lessee 
Owned Alterations or Utility Installations be removed by the expiration or 
termination of this Lease.  Lessor may require the removal at any time of all 
or any part of any Lessee Owned Alterations or Utility Installations made 
without the required consent.

          (c)  SURRENDER/RESTORATION.  Lessee shall surrender the Premises by 
the Expiration Date or any earlier termination date, with all of the 
improvements, parts and surfaces thereof broom clean and free of debris, and 
in good operating order, condition and state of repair, ordinary wear and 
tear excepted.  "Ordinary wear and tear" shall not include any damage or 
deterioration that would have been prevented by good maintenance practice. 
Lessee shall repair any damage occasioned by the installation, maintenance or 
removal of Trade Fixtures, Lessee Owned Alterations and/or Utility 
Installations, furnishings and equipment as well as the removal of any 
storage tank installed by or for Lessee, and the removal, replacement, or 
remediation of any soil, material or groundwater contaminated by Lessee.  
Trade Fixtures shall remain the property of Lessee and shall be removed by 
Lessee.  The failure by Lessee to timely vacate the Premises pursuant to this 
Paragraph 7.4(c) without the express written consent of Lessor shall 
constitute a holdover under the provisions of Paragraph 26 below.

8.   INSURANCE; INDEMNITY.

     8.1  PAYMENT OF PREMIUM INCREASES.  

          (a)  Lessee shall pay to Lessor any insurance cost increase 
("Insurance Cost Increase") occurring during the term of this Lease.  
"Insurance Cost Increase" is defined as any increase in the actual cost of 
the insurance required under Paragraph 8.2(b), 8.3(a) and 8.3(b) ("Required 
Insurance"), over and above the Base Premium as hereinafter defined 
calculated on an annual basis. "Insurance Cost Increase" shall include but 
not be limited to increases resulting from the nature of Lessee's occupancy, 
any act or omission of Lessee, requirements of the holder of mortgage or deed 
of trust covering the Premises, increased valuation of the Premises and/or a 
premium rate increase.  The parties are encouraged to fill in the Base 
Premium in Paragraph 1.9 with a reasonable premium for the Required Insurance 
based on the Agreed Use of the Premises.  If the parties fail to insert a 
dollar amount in Paragraph 1.8, then the Base Premium shall be the lowest 
annual 

                                      6
<PAGE>

premium reasonably obtainable for the Required Insurance as of the 
commencement of the Original Term for the Agreed Use of the Premises.  In no 
event, however, shall Lessee be responsible for any portion of the increase 
in the premium cost attributable to liability insurance carried by Lessor 
under Paragraph 8.1(b) in excess of $2,000,000 per occurrence.

          (b)  Lessee shall pay any such Insurance Cost Increase to Lessor 
within thirty (30) days after receipt by Lessee of a copy of the premium 
statement or other reasonable evidence of the amount due.  If the insurance 
policies maintained hereunder cover other property besides the Premises, 
Lessor shall also deliver to Lessee a statement of the amount of such 
Insurance Cost Increase attributable only to the Premises showing in 
reasonable detail the manner in which such amount was computed.  Premiums for 
policy periods commencing prior to, or extending beyond the term of this 
Lease, shall be prorated to correspond to the term of this Lease.

     8.2  LIABILITY INSURANCE.

          (a)  CARRIED BY LESSEE.  Lessee shall obtain and keep in force a 
Commercial General Liability Policy of Insurance protecting Lessee and Lessor 
against claims for bodily injury, personal injury and property damage based 
upon or arising out of the ownership, use, occupancy or maintenance of the 
Premises and all areas appurtenant thereto.  Such insurance shall be on an 
occurrence basis providing single limit coverage in an amount not less than 
$2,000,000 per occurrence with an "Additional Insured-Managers or Lessors of 
Premises Endorsement" and contain the "Amendment of the Pollution Exclusion 
Endorsement" for damage caused by heat, smoke or fumes from a hostile fire.  
The Policy shall not contain any intra-insured exclusions as between insured 
persons or organizations, but shall include coverage for liability assumed 
under this Lease as an "insured contract" for the performance of Lessee's 
indemnity obligations under this Lease.  The limits of said insurance shall 
not, however, limit the liability of Lessee nor relieve Lessee of any 
obligation hereunder.  All insurance carried by Lessee shall be primary to 
and not contributory with any similar insurance carried by Lessor, whose 
insurance shall be considered excess insurance only.

          (b)  CARRIED BY LESSOR.  Lessor shall maintain liability insurance 
as described in Paragraph 8.2(a) in addition to, and not in lieu of, the 
insurance required to be maintained by Lessee.  Lessee shall not be named as 
an additional insured therein

     8.3  PROPERTY INSURANCE - BUILDING, IMPROVEMENTS AND RENTAL VALUE.

          (a)  BUILDING AND IMPROVEMENTS.  The Insuring Party shall obtain 
and keep in force a policy or policies in the name of Lessor, with loss 
payable to Lessor, any groundlessor, and to any Lender(s) insuring loss or 
damage to the Premises.  The amount of such insurance shall be equal to the 
full replacement cost of the Premises, as the same shall exist from time to 
time, or the amount required by any Lenders, but in no event more than the 
commercially reasonable and available insurable value thereof.  If Lessor is 
the Insuring Party, however, Lessee Owned Alterations and Utility 
Installations, Trade Fixtures, and Lessee's personal property shall be 
insured by Lessee under Paragraph 8.4 rather than by Lessor.  If the coverage 
is available and commercially appropriate, such policy or policies shall 
insure against all risks of direct physical loss or damage (except the perils 
of flood and/or earthquake unless required by a Lender or included in the 
Base Premium), including coverage for debris removal and the enforcement of 
any Applicable Requirements requiring the upgrading, reconstruction or 
replacement of any portion of the Premises as the result of the covered loss. 
Said policy or policies shall also contain an agreed valuation provision in 
lieu of any coinsurance clause, waiver of subrogation, and inflation guard 
protection causing an increase in the annual property insurance coverage 
amount by a factor of not less than the adjusted U.S. Department of Labor 
Consumer Price Index for All Urban Consumers for the city nearest to where 
the Premises are located.  

          (b)  RENTAL VALUE.  The Insuring Party shall obtain and keep in 
force a policy or policies in the name of Lessor, with loss payable to Lessor 
and any Lender, insuring the loss of the full Rent for one (1) year.  Said 
insurance shall provide that in the event the Lease is terminated by reason 
of an insured loss, the period of indemnity for such coverage shall be 
extended beyond the date of the completion of repairs or replacement of the 
Premises, to provide for one full year's loss of Rent from the date of any 
such loss.  Said insurance shall contain an agreed valuation provision in 
lieu of any coinsurance clause, and the amount of coverage shall be adjusted 
annually to reflect the projected Rent otherwise payable by Lessee, for the 
next twelve (12) month period.

          (c)  ADJACENT PREMISES.  If the Premises are part of a larger 
building, or of a group of buildings owned by Lessor which are adjacent  to 
the Premises, the Lessee shall pay for any increase in the premiums for the 
property insurance of such building or buildings if said increase is caused 
by Lessee's acts, omissions, use or occupancy of the Premises.

                                      7

     8.4  LESSEE'S PROPERTY/BUSINESS INTERRUPTION INSURANCE.

          (a)  PROPERTY DAMAGE.  Lessee shall obtain and maintain insurance 
coverage on all of Lessee's personal property, Trade Fixtures, and Lessee 
Owned Alterations and Utility Installations.  Such insurance shall be full 
replacement cost coverage with a deductible of not to exceed $10,000 per 
occurrence.  The proceeds from any such insurance shall be used by Lessee for 
the replacement of personal property, Trade Fixtures and Lessee Owned 
Alterations and Utility Installations.  Lessee shall provide Lessor with 
written evidence that such insurance is in force.

          (b)  BUSINESS INTERRUPTION.  Lessee shall obtain and maintain loss 
of income and extra expense insurance in amounts as will reimburse Lessee for 
direct or indirect loss of earnings attributable to all perils commonly 
insured against by prudent lessees in the business of Lessee or attributable 
to prevention of access to the Premises as a result of such perils.

          (c)  NO REPRESENTATION OF ADEQUATE COVERAGE.  Lessor makes no 
representation that the limits or forms of coverage of insurance specified 
herein are adequate to cover Lessee's property, business operations or 
obligations under this Lease.

     8.5  INSURANCE POLICIES.  Insurance required hereunder shall be by 
companies duly licensed or admitted to transact business in the state where 
the Premises are located, and maintaining during the policy term a "General 
Policyholders Rating" of at least B +, V, as set forth in the most current 
issue of "Best's Insurance Guide," or such other rating as may be required by 
a Lender.  Lessee shall not do or permit to be done anything which 
invalidates the required insurance policies.  Lessee shall, prior to the 
Start Date, deliver to Lessor certified copies of policies of such insurance 
or certificates evidencing the existence and amounts of the required 
insurance.  No such policy shall be cancelable or subject to modification 
except after thirty (30) days' prior written notice to Lessor.  Lessee shall, 
at least thirty (30) days prior to the expiration of such policies, furnish 
Lessor with evidence of renewals or "insurance binders" evidencing renewal 
thereof, or Lessor may order such insurance and charge the cost thereof to 
Lessee, which amount shall be payable by Lessee to Lessor upon demand.  Such 
policies shall be for a term of at least one year, or the length of the 
remaining term of this Lease, whichever is less. If either Party shall fail 
to procure and maintain the insurance required to be carried by it, the other 
Party may, but shall not be required to, procure and maintain the same.

     8.6  WAIVER OF SUBROGATION.  Without affecting any other rights or 
remedies, Lessee and Lessor each hereby release and relieve the other, and 
waive their entire right to recover damages against the other, for loss of or 
damage to its property arising out of or incident to the perils required to 
be insured against herein.  The effect of such releases and waivers is not 
limited by the amount of insurance carried or required, or by any deductibles 
applicable thereto.  The Parties agree to have their respective property 
damage insurance carriers waive any right to subrogation that such companies 
may have against Lessor or Lessee, as the case may be, so long as the 
insurance is not invalidated thereby.

     8.7  INDEMNITY.  Except for Lessor's negligence or willful misconduct, 
Lessee shall indemnify, protect, defend and hold harmless the Premises, 
Lessor and its agents, Lessor's master or ground lessor, partners and 
Lenders, from and against any and all claims, loss of rents and/or damages, 
liens, judgments, penalties, attorneys' and consultants' fees, expenses 
and/or liabilities arising out of, involving, or in connection with, the use 
and/or occupancy of the Premises by Lessee.  If any action or proceeding is 
brought against Lessor by reason of any of the foregoing matters, Lessee 
shall upon notice defend the same at Lessee's expense by counsel reasonably 
satisfactory to Lessor and Lessor shall cooperate with Lessee in such 
defense.  Lessor need not have first paid any such claim in order to be 
defended or indemnified.

     8.8  EXEMPTION OF LESSOR FROM LIABILITY.  Lessor shall not be liable for 
injury or damage to the person or goods, wares, merchandise or other property 
of Lessee, Lessee's employees, contractors, invitees, customers, or any other 
person in or about the Premises, whether such damage or injury is caused by 
or results from fire, steam, electricity, gas, water or rain, or from the 
breakage, leakage, obstruction or other defects of pipes, fire sprinklers, 
wires, appliances, plumbing, HVAC or lighting fixtures, or from any other 
cause, whether the said injury or damage results from conditions arising upon 
the Premises or upon other portions of the Building of which the Premises are 
a part, or from other sources or places.  Lessor shall not be liable for any 
damages arising from any act or neglect of any other tenant of Lessor. 
Notwithstanding Lessor's negligence or breach of this Lease, Lessor shall 
under no circumstances be liable for injury to Lessee's business or for any 
loss of income or profit therefrom.

9.   DAMAGE OR DESTRUCTION.

     9.1  DEFINITIONS.

          (a)  "PREMISES PARTIAL DAMAGE" shall mean damage or destruction to 
the improvements on the Premises, other than Lessee Owned Alterations, 
Utility Installations and Trade Fixtures, which can reasonably be repaired in 
six (6) months or less from the date of the damage or destruction.  Lessor 
shall notify Lessee in writing within thirty (30) days from the date of the 
damage or destruction as to whether or not the damage is Partial or Total.

          (b)  "PREMISES TOTAL DESTRUCTION" shall mean damage or destruction 
to the Premises, other than Lessee Owned Alterations and Utility 
Installations and Trade Fixtures, which cannot reasonably be repaired in six 
(6) months or less from the date of the damage or destruction.  Lessor shall 
notify Lessee in writing within thirty (30) days from the date of the damage 
or destruction as to whether or not the damage is Partial or Total.

          (c)  "INSURED LOSS" shall mean damage or destruction to 
improvements on the Premises, other than Lessee Owned Alterations and Utility 
Installations and Trade Fixtures, which was caused by an event required to be 
covered by the insurance described in Paragraph 8.3(a), irrespective of any 
deductible amounts or coverage limits involved.

          (d)  "REPLACEMENT COST" shall mean the cost to repair or rebuild 
the improvements owned by Lessor at the time of the occurrence to their 
condition existing immediately prior thereto, including demolition, debris 
removal and upgrading required by the operation of Applicable Requirements, 
and without deduction for depreciation.

          (e)  HAZARDOUS SUBSTANCE CONDITION" shall mean the occurrence or 
discovery of a condition involving the presence of, or a contamination by, a 
Hazardous Substance as defined in Paragraph 6.2(a), in, on, or under the 
Premises.

     9.2  PARTIAL DAMAGE -- INSURED LOSS.  If a Premises Partial Damage that 
is an Insured Loss occurs, then Lessor shall, at Lessor's expense, repair 
such damage (but not Lessee's Trade Fixtures or Lessee Owned Alterations and 
Utility Installations) as soon as reasonably possible and this Lease shall 
continue in full force and effect; provided, however, that Lessee shall, at 
Lessor's election, make the repair of any damage or destruction the total 
cost to repair of which is  $10,000 or less, and, in such event, Lessor shall 
make any applicable insurance proceeds available to Lessee on a reasonable 
basis for that purpose.  Notwithstanding the foregoing, if the required 
insurance was not in force or the insurance proceeds are not sufficient to 
effect such repair, the Insuring Party shall promptly contribute the shortage 
in proceeds as and when required to complete said repairs.  In the event, 
however, such shortage was due to the fact that, by reason of the unique 
nature of the improvements, full replacement cost insurance coverage was not 
commercially reasonable and available, Lessor shall have no obligation to pay 
for the shortage in insurance proceeds or to fully restore the unique aspects 
of the Premises unless Lessee provides Lessor with the funds to cover same, 
or adequate assurance thereof, within ten (10) days following receipt of 
written notice of such shortage and request therefor.  If Lessor receives 
said funds or adequate assurance thereof within said ten (10) day period, the 
party responsible for making the repairs shall complete them as soon as 
reasonably possible and this Lease shall remain in full force and effect.  If 
such funds or assurance are not received, Lessor may nevertheless elect by 
written notice to Lessee within ten (10) days thereafter to:  (i) make such 
restoration and repair as is commercially reasonable with Lessor paying any 
shortage in proceeds, in which case this Lease shall remain in full force and 
effect; or (ii) have this Lease terminate thirty (30) days thereafter.  
Lessee shall not be entitled to reimbursement of any funds contributed by 
Lessee to repair any such damage or destruction.  Premises Partial Damage due 
to flood or earthquake shall be subject to Paragraph 9.3, notwithstanding 
that there may be some insurance coverage, but the net proceeds of any such 
insurance shall be made available for the repairs if made by either Party.

     9.3  PARTIAL DAMAGE -- UNINSURED LOSS.  If a Premises Partial Damage that 
is not an Insured Loss occurs, unless caused by a negligent or willful act of 
Lessee (in which event Lessee shall make the repairs at Lessee's expense), 
Lessor may either:  (i) repair such damage as soon as reasonably possible at 
Lessor's expense, in which event this Lease shall continue in full force and 
effect, or (ii) terminate this Lease by giving written notice to Lessee 
within thirty (30) days after receipt by Lessor of knowledge of the 
occurrence of such damage.  Such termination shall be effective sixty (60) 
days following the date of such notice.  In the event Lessor elects to 
terminate this Lease, Lessee shall have the right within ten (10) days after 
the receipt of the termination notice to give written notice to Lessor of 
Lessee's commitment to pay for the repair of such damage without 
reimbursement from Lessor.  Lessee shall provide Lessor with said funds or 
satisfactory assurance thereof within thirty (30) days after making such 
commitment.  In such event this Lease shall continue in full force and 
effect, and Lessor shall proceed to make such repairs as soon as reasonably 
possible after the required funds are 

                                      9
<PAGE>

available.  If Lessee does not make the required commitment, this Lease shall 
terminate as of the date specified in the termination notice.

     9.4  TOTAL DESTRUCTION.  Notwithstanding any other provision hereof, if 
a Premises Total Destruction occurs, this Lease shall terminate sixty (60) 
days following the date of such Destruction.  If the damage or destruction 
was caused by gross negligence or willful misconduct of Lessee, Lessor shall 
have the right to recover Lessor's damages from Lessee except as released and 
waived in Paragraph 8.6.

     9.5  DAMAGE NEAR END OF TERM.  If at any time during the last six (6) 
months of this Lease there is damage for which the cost to repair exceeds one 
(1) month's Base Rent, whether or not an Insured Loss, Lessor may terminate 
this Lease effective sixty (60) days following the date of occurrence of such 
damage by giving written termination notice to Lessee within thirty (30) days 
after the date of occurrence of such damage.  Notwithstanding the foregoing, 
if Lessee at that time has an exercisable option to extend this Lease or to 
purchase the Premises, then Lessee may preserve this Lease by, (a) exercising 
such option and (b) providing Lessor with any shortage in insurance proceeds 
(or adequate assurance thereof) needed to make the repairs on or before the 
earlier of (i) the date which is ten days after Lessee's receipt of Lessor's 
written notice purporting to terminate this Lease, or (ii) the day prior to 
the date upon which such option expires.  If Lessee duly exercises such 
option during such Period and provides Lessor with funds (or adequate 
assurance thereof) to cover any shortage in insurance proceeds, Lessor shall, 
at Lessor's commercially reasonable expense, repair such damage as soon as 
reasonably possible and this Lease shall continue in full force and effect.  
If Lessee fails to exercise such option and provide such funds or assurance 
during such period, then this Lease shall terminate on the date specified in 
the termination notice and Lessee's option shall be extinguished.

     9.6  ABATEMENT OF RENT; LESSEE'S REMEDIES.

          (a)  ABATEMENT.  In the event of Premises Partial Damage or 
Premises Total Destruction or a Hazardous Substance Condition for which 
Lessee is not responsible under this Lease, the Rent payable by Lessee for 
the period required for the repair, remediation or restoration of such damage 
shall be abated in proportion to the degree to which Lessee's use of the 
Premises is impaired, but not to exceed the proceeds received from the Rental 
Value insurance.  All other obligations of Lessee hereunder shall be 
performed by Lessee, and Lessor shall have no liability for any such damage, 
destruction, remediation, repair or restoration except as provided herein.

          (b)  REMEDIES.  If Lessor shall be obligated to repair or restore 
the Premises and does not commence, in a substantial and meaningful way, such 
repair or restoration within ninety (90) days after such obligation shall 
accrue, Lessee may, at any time prior to the commencement of such repair or 
restoration, give written notice to Lessor and to any Lenders of which Lessee 
has actual notice, of Lessee's election to terminate this Lease on a date not 
less than sixty (60) days following the giving of such notice.  If Lessee 
gives such notice and such repair or restoration is not commenced within 
thirty (30) days thereafter, this Lease shall terminate as of the date 
specified in said notice. If the repair or restoration is commenced within 
said thirty (30) days, this Lease shall continue in full force and effect.  
"COMMENCE" shall mean either the unconditional authorization of the 
preparation of the required plans, or the beginning of the actual work on the 
Premises, whichever first occurs.

     9.7  TERMINATION -- ADVANCE PAYMENTS.  Upon termination of this Lease 
pursuant to Paragraph 6.2(g) or Paragraph 9, an equitable adjustment shall be 
made concerning advance Base Rent and any other advance payments made by 
Lessee to Lessor.  Lessor shall, in addition, return to Lessee so much of 
Lessee's Security Deposit as has not been, or is not then required to be, 
used by Lessor.

     9.8  WAIVE STATUTES.  Lessor and Lessee agree that the terms of this 
Lease shall govern the effect of any damage to or destruction of the Premises 
with respect to the termination of this Lease and hereby waive the provisions 
of any present or future statute to the extent inconsistent herewith.

10.  REAL PROPERTY TAXES.

     10.1 DEFINITION OF "REAL PROPERTY TAXES."  As used herein, the term 
"REAL PROPERTY TAXES" shall include any form of assessment; real estate, 
general, special, ordinary or extraordinary, or rental levy or tax (other 
than inheritance, personal income or estate taxes); improvement bond; and/or 
license fee imposed upon or levied against any legal or equitable interest of 
Lessor in the Premises, Lessor's right to other income therefrom, and/or 
Lessor's business of leasing, by any authority having the direct or indirect 
power to tax and where the funds are generated with reference to the Building 
address and where the proceeds so generated are to be applied by the city, 
county or other local taxing authority of a jurisdiction within which the 
Premises are located.  The term "Real Property Taxes" shall also include any 
tax, fee, levy, assessment or charge, or any 

                                      10
<PAGE>

increase therein, imposed by reason of events occurring during the term of 
this Lease, including but not limited to, a change in the ownership of the 
Premises.

     10.2

          (a)  PAYMENT OF TAXES.  Lessor shall pay the Real Property Taxes 
applicable to the Premises provided, however, that Lessee shall pay to Lessor 
the amount, if any, by which Real Property Taxes applicable to the Premises 
over the fiscal tax year during which the Commencement Date occurs ("Tax 
Increase"). Subject to Paragraph 10.2(b), payment of any such Tax Increase 
shall be made by Lessee to Lessor within thirty (30) days after receipt of 
Lessor's written statement setting forth the amount due and the computation 
thereof, if any such taxes shall cover any period of time prior to or after 
the expiration or termination of this Lease, Lessee's share of such taxes 
shall be prorated to cover only that portion of the tax bill applicable to 
the period that this Lease is in effect.

          (b)  ADVANCE PAYMENT.  In the event Lessee incurs a late charge on 
any Rent payment, Lessor may, at Lessor's option, estimate the current Real 
Property Taxes, and require that the Tax Increase be paid in advance to 
Lessor by Lessee, either: (i) in a lump sum amount equal to the amount due, 
at least twenty (20) days prior to the applicable delinquency date; or (ii) 
monthly in advance with the payment of the Base Rent.  If Lessor elects to 
require payment monthly in advance, the monthly payment shall be an amount 
equal to the amount of the estimated installment of the Tax Increase divided 
by the number of months remaining before the month in which said installment 
becomes delinquent.  When the actual amount of the applicable Tax Increase is 
known, the amount of such equal monthly advance payments shall be adjusted as 
required to provide the funds needed to pay the applicable Tax Increase.  If 
the amount collected by Lessor is insufficient to pay the Tax Increase when 
due, Lessee shall pay Lessor, upon demand, such additional sums as are 
necessary to pay such obligations.  All monies paid to Lessor under this 
Paragraph may be intermingled with other monies of Lessor and shall not bear 
interest.  In the event of a Breach by Lessee in the performance of its 
obligations under this Lease, then any balance of funds paid to Lessor under 
the provisions of this Paragraph may at the option of Lessor, be treated as 
an additional Security Deposit.

          (c)  ADDITIONAL IMPROVEMENTS.  Notwithstanding anything to the 
contrary in this Paragraph 10.2, Lessee shall pay to Lessor upon demand 
therefor the entirety of any increase in Real Property Taxes assessed by 
reason of Alterations or Utility Installations placed upon the Premises by 
Lessee or at Lessee's request.

     10.3 JOINT ASSESSMENT.  If the Premises are not separately assessed, 
Lessee's liability shall be an equitable proportion of the Tax Increase for 
all of the land and improvements included within the tax parcel assessed, 
such proportion to be conclusively determined by Lessor from the respective 
valuations assigned in the assessor's work sheets or such other information 
as may be reasonably available.  

     10.4 PERSONAL PROPERTY TAXES.  Lessee shall pay, prior to delinquency, 
all taxes assessed against and levied upon Lessee Owned Alterations, Utility 
Installations, Trade Fixtures, furnishings, equipment and all personal 
property of Lessee.  When possible, Lessee shall cause such property to be 
assessed and billed separately from the real property of Lessor.  If any of 
Lessee's said personal property shall be assessed with Lessor's real 
property, Lessee shall pay Lessor the taxes attributable to Lessee's property 
within ten (10) days after receipt of a written statement.

11.  UTILITIES.  Lessee shall pay for all water, gas, heat, light, power, 
telephone, trash disposal and other utilities and services supplied to the 
Premises, together with any taxes thereon.  If any such services are not 
separately metered to Lessee, Lessee shall pay a reasonable proportion, to be 
determined by Lessor, of all changes jointly metered.

12.  ASSIGNMENT AND SUBLETTING.

     12.1 LESSOR'S CONSENT REQUIRED.

          (a)  Lessee shall not voluntarily or by operation of law assign, 
transfer, mortgage or encumber (collectively, "ASSIGN OR ASSIGNMENT") or 
sublet all or any part of Lessee's interest in this Lease or in the Premises 
without Lessor's prior written consent.

          (b)  A change in the control of Lessee shall constitute an 
assignment requiring consent.  The transfer, on a cumulative basis, of fifty 
percent (50%) or more of the voting control of Lessee shall constitute a 
change in control for this purpose.



                                      11
<PAGE>

          (c)  The involvement of Lessee or its assets in any transaction, or 
series of transactions (by way of merger, sale, acquisition, financing, 
transfer, leveraged buy-out or otherwise), whether or not a formal assignment 
or hypothecation of this Lease or Lessee's assets occurs, which results or 
will result in a reduction of the Net Worth of Lessee by an amount greater 
than fifty percent (50%) of such Net Worth as it was represented at the time 
of the execution of this Lease or at the time of the most recent assignment 
to which Lessor has consented, or as it exists immediately prior to said 
transaction or transactions constituting such reduction, whichever was or is 
greater, shall be considered an assignment of this Lease to which Lessor may 
withhold its consent. "NET WORTH OF LESSEE" shall mean the net worth of 
Lessee (excluding any guarantors) established under generally accepted 
accounting principles.

          (d)  An assignment or subletting without consent shall, at Lessor's 
option, be a Default curable after notice per Paragraph 13.1(c), or a 
noncurable Breach without the necessity of any notice and grace period.  If 
Lessor elects to treat such unapproved assignment or subletting as a 
noncurable Breach, Lessor may either:  (i) terminate this Lease, or (ii) upon 
thirty (30) days' written notice, increase the monthly Base Rent to one 
hundred ten percent (110%) of the Base Rent then in effect.  Further, in the 
event of such Breach and rental adjustments, (i) the purchase price of any 
option to purchase the Premises held by Lessee shall be subject to similar 
adjustment to one hundred ten percent (110%) of the price previously in 
effect, and (ii) all fixed and non-fixed rental adjustment scheduled during 
the remainder of the Lease term shall be increased to One Hundred Ten Percent 
(110%) of the scheduled adjusted rent.

          (e)  Lessee's remedy for any breach of this Paragraph 12.1 by 
Lessor shall be limited to compensatory damages and/or injunctive relief.

     12.2 TERMS AND CONDITIONS APPLICABLE TO ASSIGNMENT AND SUBLETTING.

          (a)  Regardless of Lessor's consent, any assignment or subletting 
shall not:  (i) be effective without the express written assumption by such 
assignee or sublessee of the obligations of Lessee under this Lease; (ii) 
release Lessee of any obligations hereunder; or (iii) alter the primary 
liability of Lessee for the payment of Rent or for the performance of any 
other obligations to be performed by Lessee.

          (b)  Lessor may accept any Rent or performance of Lessee's 
obligations from any person other than Lessee pending approval or disapproval 
of an assignment.  Neither a delay in the approval or disapproval of such 
assignment nor the acceptance of Rent or performance shall constitute a 
waiver or estoppel of Lessor's right to exercise its remedies for Lessee's 
Default or Breach.

          (c)  Lessor's consent to any assignment or subletting shall not 
constitute a consent to any subsequent assignment or subletting.

          (d)  In the event of any Default or Breach by Lessee, Lessor may 
proceed directly against Lessee, any Guarantors or anyone else responsible 
for the performance of the Lessee's obligations under this Lease, including 
any assignee or sublessee, without first exhausting Lessor's remedies against 
any other person or entity responsible therefor to Lessor, or any security 
held by Lessor.

          (e)  Each request for consent to an assignment or subletting shall 
be in writing, accompanied by information relevant to Lessor's determination 
as to the financial and operational responsibility and appropriateness of the 
proposed assignee or sublessee, including but not limited to the intended use 
and/or required modification of the Premises, if any, together with a fee of 
$1,000 or ten percent (10%) of the current monthly Base Rent applicable to 
the portion of the Premises which is the subject of the proposed assignment 
or sublease, whichever is greater, as consideration for Lessor's considering 
and processing said request.  Lessee agrees to provide Lessor with such other 
or additional information and/or documentation as may be reasonably requested.

          (f)  Any assignee of, or sublessee under, this Lease shall, by 
reason of accepting such assignment or entering into such sublease, be deemed 
to have assumed and agreed to conform and comply with each and every term, 
covenant, condition and obligation herein to be observed or performed by 
Lessee during the term of said assignment or sublease, other than such 
obligations as are contrary to or inconsistent with provisions of an 
assignment or sublease to which Lessor has specifically consented in writing.

     12.3 ADDITIONAL TERMS AND CONDITIONS APPLICABLE TO SUBLETTING.  The 
following terms and conditions shall apply to any subletting by Lessee of all 
or any part of the Premises and shall be deemed included in all subleases 
under this Lease whether or not expressly incorporated therein:

          (a)  Lessee hereby assigns and transfers to Lessor all of Lessee's
interest in all Rent payable on any sublease, and Lessor may collect such Rent
and apply same toward Lessee's obligations under this

                                      12

<PAGE>

Lease; provided, however, that until a Breach shall occur in the performance 
of Lessee's obligation, Lessee may collect said Rent.  Lessor shall not, by 
reason of the foregoing or any assignment of such sublease, nor by reason of 
the collection of Rent, be deemed liable to the sublessee for any failure of 
Lessee to perform and comply with any of lessee's obligations to such 
sublessee, Lessee hereby irrevocably authorizes and directs any such 
sublessee, upon receipt of a written notice front Lessor stating that a 
Breach exists in the performance of Lessee's obligations under this Lease, to 
pay to Lessor all Rent due and to become due under the sublease.  Sublessee 
shall rely upon any such notice from Lessor and shall pay all Rents to Lessor 
without any obligation or right to inquire as to whether such Breach exists, 
notwithstanding any claim from Lessee to the contrary.

          (b)  In the event of a Breach by Lessee, Lessor may, at is option, 
require sublessee to attorn to Lesser, in which event Lessor shall undertake 
the obligations of the sublessor under such sublease from the time of the 
exercise of said option to the expiration of such sublease; provided, 
however, Lessor shall not be liable for any prepaid rents or security deposit 
paid by such sublessee to such sublessor or for any prior Defaults or 
Breaches of such sublessor.

          (c)  Any matter requiring the consent of the sublessor under a 
sublease shall also require the consent of Lessor.

          (d)  No sublessee shall further assign or sublet all or any part of 
the Premises without Lessor's prior written consent.

          (e)  Lessor shall deliver a copy of any notice of Default or Breach 
by Lessee to the sublessee, who shall have the right to cure the Default of 
Lessee within the grace period, if any, specified in such notice.  The 
sublessee shall have a right of reimbursement and offset from and against 
Lessee for any such Defaults cured by the sublessee.

13.  DEFAULT; BREACH; REMEDIES.

    13.1. DEFAULT; BREACH.  A "DEFAULT" is defined as a failure by the Lessee 
to comply with or perform any of the terms, covenants, conditions or rules 
under this Lease.  A "BREACH" is defined as the occurrence of one or more of 
the following Defaults, and the failure of Lessee to cure such Default within 
any applicable grace period:

          (a)  The abandonment of the Premises; or the vacating of the 
Premises without providing a commercially reasonable level of security, 
and/or Security Deposit or where the coverage of the property insurance 
described in Paragraph 8.3 is jeopardized as a result thereof, or without 
providing reasonable assurances to minimize potential vandalism.

          (b)  The failure of Lessee to make any payment of Rent or any 
Security Deposit required to be made by Lessee hereunder, whether to Lessor 
or to a third party, when due, to provide reasonable evidence of insurance or 
surety bond, or to fulfill any obligation under this Lease which endangers or 
threatens life or property, where such failure continues for a period of five 
(5) business days following written notice to Lessee.  

          (c)  The failure by Lessee to provide (i) reasonable written 
evidence of compliance with Applicable Requirements, (ii) the service 
contracts, (iii) the rescission of an unauthorized assignment or subletting, 
(iv) an Estoppel Certificate, (v) a requested subordination, (vi) evidence 
concerning any guaranty and/or Guarantor, (vii) any document requested under 
Paragraph 42 (easements), or (viii) any other documentation or information 
which Lessor may reasonably require of Lessee under the terms of this Lease, 
where any such failure continues for a period of ten (10) days following 
written notice to Lessee.

          (d)  A Default by Lessee as to the terms, covenants, conditions or 
provisions of this Lease, or of the rules adopted under Paragraph 40 hereof, 
other than those described in subparagraphs 13.1(a), (b) or (c), above, where 
such Default continues for a period of thirty (30) days after written notice; 
provided, however, that if the nature of Lessee's Default is such that more 
than thirty (30) days are reasonably inquired for its cure, then it shall not 
be deemed to be a Breach if Lessee commences such cure within said thirty 
(30) day period and thereafter diligently prosecutes such cure to completion.

          (e)  The occurrence of any of the following events:  (i) the making 
of any general arrangement or assignment for the benefit of creditors; (ii) 
becoming a "DEBTOR" as defined in 11 U.S.C. Section  101 or any successor 
statute thereto (unless, in the case of a petition filed against Lessee, the 
same is dismissed within sixty (60) days); (iii) the appointment of a trustee 
or receiver to take possession of substantially all of Lessee's assets 
located at the Premises or of Lessee's interest in this Lease, where 
possession is not restored to Lessee within thirty (30) days; or (iv) the 
attachment, execution or other judicial seizure of substantially all of 
Lessee's assets located at the Premises or of Lessee's interest in this 
Lease, where such seizure is not discharged

                                      13

<PAGE>

within thirty (30) days; provided, however, in the event that any provision 
of this subparagraph (e) is contrary to any applicable law, such provision 
shall be of no force or effect, and not affect the validity of the remaining 
provisions.

          (f)  The discovery that any financial statement of lessee or of any 
Guarantor given to Lessor was materially false.

          (g)  If the performance of Lessee's obligations under this Lease is 
guaranteed:  (i) the death of a Guarantor; (ii) the termination of a 
Guarantor's liability with respect to this Lease other than in accordance 
with the term of such guaranty; (iii) a Guarantor's becoming insolvent or the 
subject of a bankruptcy filing; (iv) a Guarantor's refusal to honor the 
guaranty; or (v) a Guarantor's breach of its guaranty obligation on an 
anticipatory basis, and Lessee's failure, within sixty (60) days following 
written notice of any such event, to provide written alternative assurance or 
security, which, when coupled with the then existing resources of Lessee, 
equals or exceeds the combined resources of Lessee and the Guarantors that 
existed at the time of execution of this Lease.  

     13.2 REMEDIES.  If Lessee fails to perform any of its affirmative duties 
or obligations due to insufficient funds, within ten (10) days after written 
notice (or in case of an emergency, without notice), Lessor may, at its 
option, perform such duty or obligation on Lessee's behalf, including but not 
limited to the obtaining of reasonably required bonds, insurance policies, or 
governmental licenses, permits or approvals.  The costs and expenses of any 
such performance by Lessor shall be due and payable by Lessee upon receipt of 
invoice therefor. If any check given to Lessor by Lessee shall not be honored 
by the bank upon which it is drawn, Lessor, at its option, may require all 
future payments to be made by Lessee to be by cashier's check.  In the event 
of a Breach, Lessor may, with or without further notice or demand, and 
without limiting Lessor in the exercise of any right or remedy which Lessor 
may have by reason of such Breach:

          (a)  Terminate Lessee's right to possession of the Premises by any 
lawful means, in which case this Lease shall terminate and Lessee shall 
immediately surrender possession to Lessor.  In such event Lessor shall be 
entitled to recover from Lessee: (i) the unpaid Rent which had been earned at 
the time of termination; (ii) the worth at the time of award of the amount by 
which the unpaid rent which would have been earned after termination until 
the time of award exceeds the amount of such rental loss that the Lessee 
proves could have been reasonably avoided; (iii) the worth at the time of 
award of the amount by the unpaid rent for the balance of the term after the 
time of award exceeds the amount of such rental loss that the Lessee proves 
could be reasonably avoided; and (iv) any other amount necessary to 
compensate Lessor for all the detriment proximately caused by Lessee's 
failure to perform its obligations under this Lease or which in the ordinary 
course of things would be likely to result therefrom, including but not 
limited to the cost of recovering possession of the Premises, expenses of 
reletting, including necessary renovation and alteration of the Premises, 
reasonable attorneys' fees, and that portion of any leasing commission paid 
by Lessor in connection with this Lease applicable to the unexpired term of 
this Lease.  The worth at the time of award of the amount referred to in 
provision (iii) of the immediately preceding sentence shall be computed by 
discounting such amount at the discount rate of the Federal Reserve Bank of 
the District within which the Premises are located at the time of award plus 
one percent (1%).  Efforts by Lessor to mitigate damages caused by Lessee's 
Breach of this Lease shall not waive Lessor's right to recover damages under 
Paragraph 12.  If termination of this Lease is obtained through the 
provisional remedy of unlawful detainer, Lessor shall have the right to 
recover in such proceeding any unpaid Rent and damages as are recoverable 
therein, or Lessor may reserve the right to recover all or any part thereof 
in a separate suit.  If a notice and grace period required under Paragraph 
13.1 was not previously given, a notice to pay rent or quit, or to perform or 
quit given to Lessee under the unlawful detainer statute shall also 
constitute the notice required by Paragraph 13.1.  In such case, the 
applicable grace period required by Paragraph 13.1 and the unlawful detainer 
statute shall run concurrently, and the failure of Lessee to cure the Default 
within the greater of the two such grace periods shall constitute both an 
unlawful detainer and a Breach of this Lease entitling Lessor to the remedies 
provided for in this Lease and/or by said statute.

          (b)  Continue this Lease and Lessee's right to possession and 
recover the Rent as it becomes due, in which event Lessee may sublet or 
assign, subject only to reasonable limitations.  Acts of maintenance, efforts 
to relet, and/or the appointment of a receiver to protect the Lessor's 
interests, shall not constitute a termination of the Lessee's right to 
possession.

          (c)  Pursue any other remedy now or hereafter available under the 
laws or judicial decisions of the state wherein the Premises are located.  
The expiration or termination of this Lease and/or the termination of 
Lessee's right to possession shall not relieve Lessee from liability under 
any indemnity provisions of this Lease as to matters occurring or accruing 
during the term hereof or by reason of Lessee's occupancy of the Premises.

                                     14

<PAGE>

     13.3 INDUCEMENT RECAPTURE.  Any agreement for free or abated rent 
charges, or for the giving or paying by Lessor to or for Lessee of any cash 
or other bonus, inducement or consideration for Lessee's entering into Lease, 
all of which concessions are hereinafter referred to as "INDUCEMENT 
PROVISIONS," shall be deemed conditioned upon Lessee's full and faithful 
performance of all of the terms, covenants and conditions of this Lease.  
Upon Breach of this Lease by Lessee, any such Inducement Provision shall 
automatically be deemed deleted from this Lease and of no further force or 
effect, and any rent, other charge, bonus, inducement or consideration 
theretofore abated, given or paid by Lessor under such an Inducement 
Provision shall be immediately due and payable by Lessee to Lessor, 
notwithstanding any subsequent cure of said Breach by Lessee.  The acceptance 
by Lessor of rent or the cure of the Breach which initiated the operation of 
this Paragraph shall not be deemed a waiver by Lessor of the provisions of 
this paragraph unless specifically so stated in writing by Lessor at the time 
of such acceptance.

     13.4 LATE CHARGES.  Lessee hereby acknowledges that late payment by 
Lessee of rent will cause Lessor to incur costs not contemplated by this 
Lease, the exact amount of which will be extremely difficult to ascertain.  
Such costs include, but are not limited to, processing and accounting 
charges, and late charges which may be imposed upon Lessor by any Lender.  
Accordingly, if any Rent shall not be received by Lessor or Lessor's designee 
within five (5) days after such amount shall be due, then, without any 
requirement for notice to Lessee, Lessee shall pay to Lessor a late charge 
equal to ten percent (10%) of each such overdue amount.  The parties hereby 
agree that such late charge represents a fair and reasonable estimate of the 
costs Lessor will incur by reason of such late payment.  Acceptance of such 
late charge by Lessor shall in no event constitute a waiver of Lessee's 
Default or Breach with respect to such overdue amount, nor prevent exercise 
of any of the other rights and remedies granted hereunder.  In the event that 
a late charge is payable hereunder, whether or not collected, for three (3) 
consecutive installments of Base Rent, then notwithstanding any provision of 
this Lease to the contrary, Base Rent shall, at Lessor's option, become due 
and payable quarterly in advance.

     13.5 INTEREST.  Any monetary payment due Lessor hereunder, other than 
late charges, not received by Lessor, when due as to scheduled payments (such 
as Base Rent) or within thirty (30) days following the date on which it was 
due for non-scheduled payment, shall bear interest from the date when due, as 
to scheduled payments, or the thirty-first (31st) day after it was due as to 
non-scheduled payments.  The interest ("INTEREST") charged shall be equal to 
the prime rate reported in the Wall Street Journal as published closest prior 
to the date when due plus 4%, but shall not exceed the maximum rate allowed 
by law.  Interest is payable in addition to the potential late charge 
provided for in Paragraph 13.4.

     13.6 BREACH BY LESSOR.

          (a)  NOTICE OF BREACH.  Lessor shall not be deemed in breach of 
this Lease unless Lessor fails within a reasonable time to perform an 
obligation required to be performed by Lessor.  For purposes of this 
Paragraph, a reasonable time shall in no event be less than thirty (30) days 
after receipt by Lessor, and any Lender whose name and address shall have 
been furnished Lessee in writing for such purpose, of written notice 
specifying wherein such obligation of Lessor has not been performed; 
provided, however, that if the nature of Lessor's obligation is such that 
more than thirty (30) days are reasonably required for its performance, then 
Lessor shall not be in breach if performance is commenced within such thirty 
(30) day period and thereafter diligently pursued to completion.

          (b)  PERFORMANCE BY LESSEE ON BEHALF OF LESSOR.  In the event that 
neither Lessor nor Lender cures said breach within thirty (30) days after 
receipt of said written notice, or if having commenced said cure they do not 
diligently pursue it to completion, then Lessee may elect to cure said breach 
at Lessee's expense and offset from Rent an amount equal to the greater of 
one month's Base Rent or the Security Deposit, and to pay an excess of such 
expense under protest, reserving Lessee's right to reimbursement from Lessor. 
 Lessee shall document the cost of said cure and supply said documentation to 
Lessor.

14.  CONDEMNATION.  If the Premises or any portion thereof are taken under the
power of eminent domain or sold under the threat of the exercise of said power
(collectively "CONDEMNATION"), this Lease shall terminate as to the part so
taken as of the date the condemning authority takes title or possession,
whichever first occurs.  If more than ten percent (10%) of any building portion
of the premises, or more than twenty-five percent (25%) of the land area portion
of the premises not occupied by any building, is taken by Condemnation, Lessee
may, at Lessee's option, to be exercised in writing within ten (10) days after
Lessor shall have given Lessee written notice of such taking (or in the absence
of such notice, within ten (10) days after the condemning authority shall have
taken possession) terminate this Lease as of the date the condemning authority
takes such possession.  If Lessee does not terminate this Lease in accordance
with the foregoing, this Lease shall remain in full force and effect as to the
portion of the Premises remaining, except that the Base Rent shall be reduced in
the same proportion to reduction in utility of the Premises caused by such
Condemnation.  Condemnation awards and/or payments shall be the property of
Lessor, whether such award shall be made as compensation for diminution in

                                      15

<PAGE>

value of the leasehold, the value of the part taken, or for severance 
damages; provided, however, that Lessee shall be entitled to any compensation 
for Lessee's relocation expenses, loss of business goodwill and/or Trade 
Fixtures, without regard to whether or not this Lease is terminated pursuant 
to the provisions of this Paragraph.  All Alterations and Utility 
installations made to the Premises by Lessee, for purposes of Condemnation 
only, shall be considered the property of the Lessee and Lessee shall be 
entitled to any and all compensation which is payable therefor.  In the event 
that this Lease is not terminated by reason of the Condemnation, Lessor shall 
repair any damages to the Premises caused by such Condemnation.

15.  BROKERAGE FEE.

     15.1 ADDITIONAL COMMISSION.  In addition to the payments owed pursuant 
to Paragraph 1.10 above, and unless Lessor and the Brokers otherwise agree in 
writing, Lessor agrees that; (a) if Lessee exercises any Option; (b) if 
Lessee acquires any rights to the Premises or other premises owned by Lessor 
and located within the same Project, if any, within which the Premises is 
located; (c) if Lessee remains in possession of the Premises, with the 
consent of Lessor, after the expiration of this Lease; or (d) if Base Rent is 
increased, whether by agreement or operation of an escalation clause herein, 
then, Lessor shall pay Brokers a fee in accordance with the schedule of said 
Brokers in effect at the time of the execution of this Lease.

     15.2 ASSUMPTION OF OBLIGATIONS.  Any buyer or transferee of Lessor's 
interest in this Lease shall be deemed to have assumed Lessor's obligation 
hereunder.  Each Broker shall be a third party beneficiary of the provisions 
of Paragraphs 1.10, 15, 22 and 31.  If Lessor fails to pay to a Broker any 
amounts due as and for commissions pertaining to this Lease when due, then 
such amounts shall accrue interest.  In addition, if Lessor fails to pay any 
amount to Lessee's Broker when due, Lessee's Broker may send written notice 
to Lessor and Lessee of such failure and if Lessor fails to pay such amounts 
within ten (10) days after said notice, Lessee shall pay said monies to its 
Broker and offset such amounts against Rent.  In addition, Lessee's Broker 
shall be deemed to be a third beneficiary of any commission agreement entered 
into by and/or between Lessor and Lessor's Broker.

     15.3 REPRESENTATIONS AND INDEMNITIES OF BROKER RELATIONSHIPS.  Lessee 
and Lessor each represent and warrant to the other that it has had no 
dealings with any person, firm, broker or finder (other than the Brokers, if 
any) in connection with this Lease, and that no one other than said named 
Brokers is entitled to any commission or finder's fee in connection herewith. 
Lessee and Lessor of each hereby agree to indemnify, protect, defend and 
hold the other harmless from and against liability for compensation or 
charges which may be claimed by any such unnamed broker, finder or other 
similar party by reason of any dealings or actions of the indemnifying Party, 
including any costs, expenses, attorneys' fees reasonably incurred with 
respect thereto.

16.  ESTOPPEL CERTIFICATES.

          (a)  Each Party (as "RESPONDING PARTY") shall within ten (10) 
business days after written notice from the other Party (the "REQUESTING 
PARTY") execute, acknowledge and deliver to the Requesting Party a statement 
in writing in form similar to the then most current "ESTOPPEL CERTIFICATE" 
form published by the American Industrial Real Estate Association, plus such 
additional information, confirmation and/or statements as may be reasonably 
requested by the Requesting Party.

          (b)  If the Responding Party shall fail to execute or deliver the 
Estoppel Certificate within such ten day period, the Requesting Party may 
execute an Estoppel Certificate stating that:  (i) the Lease is in full force 
and effect without modification except as may be represented by the 
Requesting Party; (ii) there are no uncured defaults in the Requesting 
Party's performance; and (iii) if Lessor is the Requesting Party, not more 
than one month's rent has been paid in advance.  Prospective purchasers and 
encumbrancers may rely upon the Requesting Party's Estoppel Certificate, and 
the Responding Party shall be estopped from denying the truth of the facts 
contained in said Certificate.

          (c)  If Lessor desires to finance, refinance, or sell the Premises, 
or any part thereof, Lessee and all Guarantors shall deliver to any potential 
lender or purchaser designated by Lessor such financial statements as may be 
reasonably required by such lender or purchaser, including but not limiting 
to Lessee's financial statements for the past three (3) years.  All such 
financial statements shall be received by Lessor and such lender or purchaser 
in confidence and shall be used only for the purposes herein set forth.

17.  DEFINITION OF LESSOR.  The term "LESSOR" as used herein shall mean the 
owner or owners at the time in question of the fee title to the Premises, or, 
if this is a sublease, of the Lessee's interest in the prior lease.  In the 
event of a transfer of Lessor's title or interest in the Premises or in this 
Lease, Lessor shall deliver to the transferee or assignee (in cash or by 
credit) any unused Security Deposit held by Lessor.  Except as provided in 
Paragraph 15, upon such transfer or assignment and delivery of the Security 
Deposit, as aforesaid, the prior Lessor shall be relieved of all liability 
with respect to the obligations and/or covenants under this Lease

                                      16

<PAGE>

thereafter to be performed by the Lessor.  Subject to the foregoing, the 
obligations and/or covenants in this Lease to be performed by the Lessor 
shall be binding only upon the Lessor as hereinabove defined.  
Notwithstanding the above, and subject to the provisions of Paragraph 20 
below, the original Lessor under this Lease, and all subsequent holders of 
the Lessor's interest in this Lease shall remain liable and responsible with 
regard to the potential duties and liabilities of Lessor pertaining to 
Hazardous Substances as outlined in Paragraph 6 above.

18.  SEVERABILITY.  The invalidity of any provision of this Lease as 
determined by a court of competent jurisdiction, shall in no way affect the 
validity of any other provision hereof.

19.  DAYS.  Unless otherwise specifically indicated to the contrary, the word 
"DAYS" as used in this Lease shall mean and refer to calendar days.

20.  LIMITATION ON LIABILITY.  Subject to the provisions of Paragraph 17 
above, the obligations of Lessor under this Lease shall not constitute 
personal obligations of Lessor, the individual partners of Lessor or its or 
their individual partners, directors, officers or shareholders, and Lessee 
shall look to the Premises, and to no other assets of Lessor, for the 
satisfaction of any liability of Lessor with respect to this Lease, and shall 
not seek recourse against the individual partners of Lessor, or its or their 
individual partners, directors, officers or shareholders, or any of their 
personal assets for such satisfaction.

21.  TIME OF ESSENCE.  Time is of the essence with respect to the performance 
of all obligations to be performed or observed by the Parties under this 
Lease.

22.  NO PRIOR OR OTHER AGREEMENTS; BROKER DISCLAIMER.  This Lease contains 
all agreements between the Parties with respect to any matter mentioned 
herein, and no other prior or contemporaneous agreement or understanding 
shall be effective. Lessor and Lessee each represents and warrants to the 
Brokers that it has made, and is relying solely upon, its own investigation 
as to the nature, quality, character and financial responsibility of the 
other Party to this Lease and as to the nature, quality and character of the 
Premises.  Brokers have no responsibility with respect thereto or with 
respect to any default or breach hereof by either Party.  The liability 
(including court costs and Attorneys' fees), of any Broker with respect to 
negotiation, execution, delivery or performance by either Lessor or Lessee 
under this Lease or any amendment or modification hereto shall be limited to 
an amount up to the fee received by such Broker pursuant to this Lease; 
provided, however, that the foregoing limitation on each Broker's liability 
shall not be applicable to any gross negligence or willful misconduct of such 
Broker.

23.  NOTICES.

     23.1 NOTICE REQUIREMENTS.  All notices required or permitted by this 
Lease shall be in writing and may be delivered in person (by hand or courier) 
or may be sent by regular, certified or registered mail or U.S. Postal 
Service Express Mail, with postage prepaid, or by facsimile transmission, and 
shall be deemed sufficiently given if served in a manner specified in this 
Paragraph 23.  The addresses noted adjacent to a Party's signature on this 
Lease shall be that Party's address for delivery or mailing of notices.  
Either Party may by written notice to the other specify a different address 
for notice, except that upon Lessee's taking possession of the Premises, the 
Premises shall constitute Lessee's address for notice.  A copy of all notices 
to Lessor shall be concurrently transmitted to such party or parties at such 
addresses as Lessor may from time to time hereafter designate in writing.  

     23.2 DATE OF NOTICE.  Any notice sent by registered or certified mail, 
return receipt requested, shall be deemed given on the date of delivery shown 
on the receipt card, or if no delivery date is shown, the postmark thereon.  
If sent by regular mail the notice shall be deemed given forty-eight (48) 
hours after the same is addressed as required herein and mailed with postage 
prepaid. Notices delivered by United States Express Mail or overnight courier 
that guarantees next day delivery shall be deemed given twenty-four (24) 
hours after delivery of the same to the Postal Service or courier.  Notices 
transmitted by facsimile transmission or similar means shall be deemed served 
upon telephone confirmation of receipt, provided a copy is also delivered via 
delivery or mail. If notice is received on a Saturday, Sunday or legal 
holiday, it shall be deemed received on the next business day.

24.  WAIVERS.  No waiver by Lessor of the Default or Breach of any term, 
covenant or condition hereof by Lessee, shall be deemed a waiver of any other 
term, covenant or condition hereof, or of any subsequent Default or Breach by 
Lessee of the same or of any other term, covenant or condition hereof.  
Lessors consent to, or approval of, any act shall not be deemed to render 
unnecessary the obtaining of Lessors consent to, or approval of, any 
subsequent or similar act by Lessee, or be construed as the basis of an 
estoppel to enforce the provision or provisions of this Lease requiring such 
consent.  The acceptance of rent by Lessor shall not be a waiver of any 
Default or Breach by Lessee.  Any payment by Lessee may be accepted by Lessor 
on account of monies or

                                      17

<PAGE>

damages due Lessor, notwithstanding any qualifying statements or conditions 
made by Lessee in connection therewith, which such statements and/or 
conditions shall be of no force or effect whatsoever unless specifically 
agreed to in writing by Lessor at or before the time of deposit of such 
payment.

25.  RECORDING.  Either Lessor or Lessee shall, upon request of the other, 
execute, acknowledge and deliver to the other a short form memorandum of this 
Lease for recording purposes.  The Party requesting recordation shall be 
responsible for payment of any fees applicable thereto.

26.  NO RIGHT TO HOLDOVER.  Lessee has no right to retain possession of the 
Premises or any part thereof beyond the expiration or termination of this 
Lease. In the event that Lessee holds over, then the Base Rent shall be 
increased to one hundred fifty percent (150%) of the Base Rent applicable 
during the month immediately preceding the expiration or termination.  
Nothing contained herein shall be construed as consent by Lessor to any 
holding over by Lessee.

27.  CUMULATIVE REMEDIES.  No remedy or election hereunder shall be deemed 
exclusive but shall, wherever possible, be cumulative with all other remedies 
at law or in equity.

28.  COVENANTS AND CONDITIONS; CONSTRUCTION OF AGREEMENT.  All provisions of 
this Lease to be observed or performed by Lessee are both covenants and 
conditions.  In construing this Lease, all headings and titles are for the 
convenience of the parties only and shall not be considered a part of this 
Lease.  Whenever required by the context, the singular shall include the 
plural and vice versa.  This Lease shall not be construed as if prepared by 
one of the parties, but rather according to its fair meaning as a whole, as 
if both parties had prepared it.

29.  BINDING EFFECT; CHOICE OF LAW.  This Lease shall be binding upon the 
parties, their personal representatives, successors and assigns and be 
governed by the laws of the State in which the Premises are located.  Any 
litigation between the Parties hereto concerning this Lease shall be 
initiated in the county in which the Premises are located.

30.  SUBORDINATION; ATTORNMENT; NON-DISTURBANCE.

     30.1 SUBORDINATION.  This Lease and any Option granted hereby shall be 
subject and subordinate to any ground lease, mortgage, deed of trust or other 
hypothecation or security device (collectively, "SECURITY DEVICE"), now or 
hereafter placed upon the Premises, to any and all advances made on the 
security thereof, and to all renewals, modifications, and extensions thereof. 
Lessee agrees that the holding any such Security Device (in this Lease 
together referred to as "LENDER") shall have no liability or obligation to 
perform any of the obligations of Lessor under this Lease.  Any Lender may 
elect to have this Lease and/or any Option granted hereby superior to the 
lien of its Security Device by giving written notice thereof to Lessee 
whereupon this Lease and such Options shall be deemed prior to such Security 
Device, notwithstanding the relative dates of the documentation or 
recordation thereof.

     30.2 ATTORNMENT.  Subject to the non-disturbance provisions of Paragraph 
30.3, Lessee agrees to attorn to a Lender or any other party who acquires 
ownership of the Premises by reason of a foreclosure of a Security Device, 
and that in the event of such foreclosure, such new owner shall not:  (i) be 
liable for any act or omission of any prior lessor or with respect to events 
occurring prior to acquisition of ownership; (ii) be subject to any offsets 
or defenses which Lessee might have against any prior lessor; or (iii) be 
bound by prepayment of more than one (1) month's rent.

     30.3 NON-DISTURBANCE.  With respect to Security Devices entered into by 
Lessor after the execution of this Lease, Lessee's subordination of this 
Lease shall be subject to receiving a commercially reasonable non-disturbance 
agreement (a "Non-Disturbance Agreement") from the Lender which 
Non-Disturbance Agreement provides that Lessee's possession of the Premises, 
and this Lease, including any options to extend the term hereof, will not be 
disturbed so long as Lessee is not in Breach hereof and attorns to the record 
owner of the Premises.  Further, within sixty (60) days after the execution 
of this Lease, Lessor shall use its commercially reasonable efforts to obtain 
a Non-Disturbance Agreement from the holder of any pre-existing Security 
Device which is secured by the Premises.  In the event that Lessor is unable 
to provide the Non-Disturbance Agreement within said sixty (60) days, then 
Lessee may, at Lessee's option, directly contract Lessor's lender and attempt 
to negotiate for the execution and delivery of a Non-Disturbance Agreement.

     30.4 SELF-EXECUTING.  The agreements contained in this Paragraph 30 
shall be effective without the execution of any further documents; provided, 
however, that, upon written request from Lessor or a Lender in connection 
with a sale, financing or refinancing of the Premises, Lessee and Lessor 
shall execute such further writings as may be reasonably required to 
separately document any such subordination, attornment and/or Non-Disturbance 
Agreement provided for herein.

                                      18

31.  ATTORNEYS' FEES.  If any Party or Broker brings an action or proceeding 
involving the Premises to enforce the terms hereof or declare rights 
hereunder, the Prevailing Party (as hereafter defined) in any such 
proceeding, action, or appeal thereof shall be entitled to reasonable 
attorneys' fees.  Such fees may be awarded in the same suit or recovered in a 
separate suit, whether or not such action or proceeding is pursued to 
decision or judgment.  The term "PREVAILING PARTY" shall include, without 
limitation, a Party or Broker who substantially obtains or defeats the relief 
sought, as the case may be.  The attorneys' fees award shall not be computed 
in accordance with any court fee schedule, but shall be such as to fully 
reimburse all attorneys' fees reasonably incurred.  In addition, Lessor shall 
be entitled to attorneys' fees, costs and expenses incurred in the 
preparation and service of notices of Default and consultations in connection 
therewith, whether or not a legal action is subsequently commenced in 
connection with such Default or resulting Breach.

32.  LESSOR'S ACCESS; SHOWING PREMISES; REPAIRS.  Lessor and Lessor's agents 
shall have the right to enter the Premises at any time, in the case of an 
emergency, and otherwise at reasonable times for the purpose of showing the 
same to prospective purchasers, lenders, or lessees, and making such 
alterations, repairs, improvements or additions to the Premises as Lessor may 
deem necessary. All such activities of Lessor shall be without abatement of 
rent or liability to Lessee.  Lessor may at any time place on the Premises 
any ordinary "For Sale" signs and Lessor may during the last six (6) months 
of the term hereof place on the Premises any ordinary "For Lease" signs.  
Lessee may at any time place on or about the Premises and ordinary "For 
Sublease" sign.

33.  AUCTIONS.  Lessee shall not conduct, nor permit to be conducted, any 
auction upon the Premises without Lessor's prior written consent.  Lessor 
shall not be obligated to exercise any standard of reasonableness in 
determining whether to permit an auction.

34.  SIGNS.  Except for ordinary "For Sublease" signs, Lessee shall not place 
any sign upon the Premises without Lessor's prior written consent.  All signs 
must comply with all Applicable Requirements.

35.  TERMINATION; MERGER.  Unless specifically stated otherwise in writing by 
Lessor, the voluntary or other surrender of this Lease by Lessee, the mutual 
termination or cancellation hereof, or a termination hereof by Lessor for 
Breach by Lessee, shall automatically terminate any sublease or lessor estate 
in the Premises; provided, however, that Lessor may elect to continue any one 
or all existing subtenancies.  Lessor's failure within ten (10) days 
following any such event to elect to the contrary by written notice to the 
holder of any such lesser interest, shall constitute Lessor's election to 
have such event constitute the termination of such interest.

36.  CONSENTS.  Except as otherwise provided herein, wherever in this Lease 
the consent of a Party is required to an act by or for the other Party, such 
consent shall not be unreasonably withheld or delayed.  Lessor's actual 
reasonable costs and expenses (including but not limited to architects', 
attorneys', engineers' and other consultants' fees) incurred in the 
consideration of, or response to, a request by Lessee for any Lessor consent, 
including but not limited to consents to an assignment, a subletting or the 
presence or use of a Hazardous Substance, shall be paid by Lessee upon 
receipt of an invoice and supporting documentation therefor.  Lessor's 
consent to any act, assignment or subletting shall not constitute an 
acknowledgment that no Default or Breach by Lessee of this Lease exists, nor 
shall such consent be deemed a waiver of any then existing Default or Breach, 
except as may be otherwise specifically stated in writing by Lessor at the 
time of such consent.  The failure to specify herein any particular condition 
to lessor's consent shall not preclude the imposition by Lessor at the time 
of consent of such further or other conditions as are then reasonable with 
reference to the particular matter for which consent is being given.  In the 
event that either Party disagrees with any determination made by the other 
hereunder and reasonably requests the reasons for such determinations, the 
determining party shall furnish its reasons in writing and in reasonable 
detail within ten (10) business days following such request.

37.  GUARANTOR.  

     37.1 EXECUTION.  The Guarantors, if any, shall each execute a guaranty 
in the form most recently published by the American Industrial Real Estate 
Association, and each Guarantor shall have the same obligations as Lessee 
under this Lease.

     37.2 DEFAULT.  It shall constitute a Default of the Lessee if any 
Guarantor fails or refuses, upon request to provide:  (a) evidence of the 
execution of the guaranty, including the authority of the party signing on 
Guarantor's behalf to obligate Guarantor, and in the case of a corporate 
Guarantor, a certified copy of a resolution of its board of directors 
authorizing the making of such guaranty, (b) current financial statements, 
(c) an Estoppel Certificate, or (d) written confirmation that the guaranty is 
still in effect.

                                      19

<PAGE>

38.  QUIET POSSESSION.  Subject to payment by Lessee of the Rent and 
performance of all of the covenants, conditions and provisions on Lessee's 
part to be observed and performed under this Lease, Lessee shall have quiet 
possession and quiet enjoyment of the premises during the term hereof.

39.  OPTIONS.

     39.1 DEFINITION.  "OPTION" shall mean:  (a) the right to extend the term 
of or renew this Lease or to extend or renew any lease that Lessee has on 
other property of Lessor; (b) the right of first refusal or first offer to 
lease either the Premises or other property of Lessor; (c) the right to 
purchase or the right of first refusal to purchase the Premises or other 
property of Lessor.

     39.2 OPTIONS PERSONAL TO ORIGINAL LESSEE.  Each Option granted to Lessee 
in this Lease is personal to the original Lessee, and cannot be assigned or 
exercised by anyone other than said original Lessee and only while the 
original Lessee is in full possession of the Premises and, if requested by 
Lessor, with Lessee certifying that Lessee has no intention of thereafter 
assigning or subletting.

     39.3 MULTIPLE OPTIONS.  In the event that Lessee has any multiple 
Options to extend or renew this Lease, a later Option cannot be exercised 
unless the prior Options have been exercised.

     39.4 EFFECT OF DEFAULT ON OPTIONS.

          (a)  Lessee shall have no right to exercise an Option:  (i) during 
the period commencing with the giving of any notice of Default and continuing 
until said Default is cured; (ii) during the period of time any Rent is 
unpaid (without regard to whether notice thereof is given Lessee); (iii) 
during the time Lessee is in Breach of this Lease; or (iv) in the event that 
Lessee has been given three (3) or more notices of separate Default, whether 
or not the Defaults are cured, during the twelve (12) month period 
immediately preceding the exercise of the Option.

          (b)  The period of time within which an Option may be exercised 
shall not be extended or enlarged by reason of Lessee's inability to exercise 
an Option because of the provisions of Paragraph 39.4(a).

          (c)  An Option shall terminate and be of no further force or 
effect, notwithstanding Lessee's due and timely exercise of the Option, if, 
after such exercise and prior to the commencement of the extended term, (i) 
Lessee fails to pay Rent for a period of thirty (30) days after such Rent 
becomes due (without any necessity of Lessor to give notice thereof), (ii) 
Lessor gives to Lessee three (3) or more notices of separate Default during 
any twelve (12) month period, whether or not the Defaults are cured, or (iii) 
if Lessee commits a Breach of this Lease.

40.  MULTIPLE BUILDINGS.  If the Premises are a part of a group of buildings 
controlled by Lessor, Lessee agrees that it will observe all reasonable rules 
and regulations which Lessor may make from time to time for the management, 
safety, and care of said properties, including the care and cleanliness of 
the grounds and including the parking, loading and unloading of vehicles, and 
that Lessee will pay its fair share of common expenses incurred in connection 
therewith.

41.  SECURITY MEASURES.  Lessee hereby acknowledges that the rental payable 
to Lessor hereunder does not include the cost of guard service or other 
security measures, and that Lessor shall have no obligation whatsoever to 
provide same. Lessee assumes all responsibility for the protection of the 
Premises, Lessee, its agents and invitees and their property from the acts of 
third parties.

42.  RESERVATIONS.  Lessor reserves to itself the right, from time to time, 
to grant, without the consent or joinder of Lessee, such easements, rights 
and dedications that Lessor deems necessary, and to cause the recordation of 
parcel maps and restrictions, so long as such easements, rights, dedications, 
maps and restrictions do not unreasonably interfere with the use of the 
Premises by Lessee.  Lessee agrees to sign any documents reasonably requested 
by Lessor to effectuate any such easement rights, dedication, map or 
restrictions.

43.  PERFORMANCE UNDER PROTEST.  If at any time a dispute shall arise as to 
any amount or sum of money to be paid by one Party to the other under the 
provisions hereof, the Party against whom the obligation to pay the money is 
asserted shall have the right to make payment "under protest" and such 
payment shall not be regarded as a voluntary payment and there shall survive 
the right on the part of said Party to institute suit for recovery of such 
sum.  If it shall be adjudged that there was no legal obligation on the part 
of said Party to pay such sum or any part thereof, said Party shall be 
entitled to recover such sum or so much thereof as it was not legally 
required to pay.

44.  AUTHORITY.  If either Party hereto is a corporation, trust, limited 
liability company, partnership, or similar entity, each individual executing 
this Lease on behalf of such entity represents and warrants that he or she is 

                                      20

45.  CONFLICT.  Any conflict between the printed provisions of this Lease and 
the typewritten or handwritten provisions shall be controlled by the 
typewritten or handwritten provisions.

46.  OFFER.  Preparation of this Lease by either Party or their agent and 
submission of same to the other Party shall not be deemed an offer to lease 
to the other Party.  This Lease is not intended to be binding until executed 
and delivered by all Parties hereto.

47.  AMENDMENTS.  This Lease may be modified only in writing, signed by the 
Parties in interest at the time of the modification.  As long as they do not 
materially change Lessee's obligations hereunder, Lessee agrees to make such 
reasonable non-monetary modifications to this Lease as may be reasonably 
required by a Lender in connection with the obtaining of normal financing or 
refinancing of the Premises.  

48.  MULTIPLE PARTIES.  If more than one person or entity is named herein as

ADDENDUM TO STANDARD INDUSTRIAL/COMMERCIAL SINGLE-TENANT LEASE-GROSS DATED 
APRIL 15, 1998 BY AND BETWEEN ROBERT STEELE, ET AL ("LESSOR") AND BURKE 
INDUSTRIES, INC. ("LESSEE") FOR THE PROPERTY LOCATED AT 10039 NORWALK 
BOULEVARD SANTA FE SPRINGS, LOS ANGELES, CALIFORNIA.

PARAGRAPH 1 - Months of June and July 1998 shall be rent-free.

PARAGRAPH 2- Lessor will do all necessary repair work on the roof to put it 
into a water-tight condition.

PARAGRAPH 3 - Lessor will be responsible for compliance with any ADA/Title 
24/Building code issues that come up during the lease that are not a result 
of Lessee's specific operations or any additional improvements that Lessee 
makes to the premiums during the lease term.

PARAGRAPH 4 - Lessor shall deliver the HVAC system in good operating 
condition prior to lease commencement.  Lessee shall maintain the HVAC system 
through a regular maintenance contract.  However, Lessee will be responsible 
for all other expenses beyond the normal maintenance required by said 
contracts.  If it is determined by an HVAC expert that the existing unit 
cannot function properly, the Lessor will replace the HVAC system, and the 
Lessee will resume the scheduled maintenance responsibility thereafter for 
the new HVAC system.

PARAGRAPH 5 - Lessor, at Lessor's expense, shall install one truck-height 
loading position.  The location shall be mutually agreed upon by Lessor and 
Lessee.  This work shall be completed as soon as reasonably possible 
recognizing that time is of the essence so that Lessee can utilize the 
truck-height loading position for its business.

PARAGRAPH 6 - Other than Lessor's work as outlined in Addendum Paragraph 2, 4 
and 5, and Lessor delivering the building in good working condition as called 
for in Paragraph 2.2 Condition, Lessee accepts the property in its "as is" 
condition.

Subject to Lessor's approval which shall not be unreasonably withheld Lessee 
may do refurbishing, make changes, alterations and/or additions to the 
premises. Lessor will reimburse Lessee for its expenses up to $100,000.  Any 
reimbursed payments over $50,000 shall be amortized over the 60 month term of 
the lease at 10%.  Example: $50,000 at 10% for 60 months would amortize at 
$1,062.35 per month or 1.895 CENTS per square foot, per month.

PARAGRAPH 7 - Rent Adjustment.  See attached/Addendum Paragraph 7.

PARAGRAPH 8 - Option to Extend.  See attached/Addendum Paragraph 8.

PARAGRAPH 9 - 6.2 Hazardous Substances

(a)  Reportable Liens Require Consent.  The term "Hazardous Substance" as used
     in this Lease shall mean any product, substance, chemical, material or
     waste whose presence, nature, quantity and/or intensity of existence, use,
     manufacture, disposal, transportation, spill, release or effect either by
     itself or in combination with other materials expected to be on the
     Premises, is either:  (i) potentially injurious to the public health,
     safety or welfare, the environment or the Premises; (ii) regulated or
     monitored by any governmental authority; or (iii) a basis for potential
     liability of Lessor to any governmental agency or third party under any
     applicable statute or common-law theory.  Hazardous Substance shall
     include, but not be limited to, hydrocarbons, petroleum, gasoline, crude
     oil or any products or byproducts thereof.  Lessee shall not engage in any
     activity in or about the premises which constitutes a Reportable Use (as
     hereinafter defined) of Hazardous Substances without the express prior
     written consent of Lessor and compliance in a timely manner, at Lessee's
     sole cost and  expense) with all Applicable Requirements (as hereinafter
     defined in paragraph 63).  "Reportable Use" shall mean (i) the installation
     or use of any above or below ground storage tank, (ii) the generation,
     possession, storage, use, transportation, or disposal of a Hazardous
     Substance that requires a permit from, or with respect to which a report,
     notice, registration or business plan is required to be filed with any
     governmental authority, and (iii) the presence in, on or about the Premises
     or neighboring properties.  Notwithstanding the foregoing, Lessee may,
     without Lessor's prior consent, but upon notice to Lessor and in compliance
     with all Applicable Requirements, use any ordinary and customary materials
     reasonably required to be used by Lessee in the normal course of the
     Permitted Use, so long as such use is not a Reportable Use and does not
     expose the Premises or neighboring properties to any meaningful risk of
     contamination or damage or expose Lessor to any liability therefor.  In
     addition, Lessor may (but without any obligation to do so) condition its
     consent to any reportable Use of any Hazardous Substance by Lessee upon
     Lessee's giving Lessor such additional assurances as Lessor, in its
     reasonable discretion, deems necessary to protect itself, the public, the
     Premises and the environment against damage, contamination or injury and/or
     liability therefor,

                                       1

<PAGE>

     including but not limited to the installation (and, at Lessor's option, 
     removal on or before Lease expiration or earlier termination) of 
     reasonably necessary protective modifications to the Premises (such as 
     concrete encasements) and/or the deposit of an additional security 
     deposit under paragraph 5 hereof.

(b)  Notice of Release.  If, during the term (including any extensions), either
     Lessor or Lessee becomes aware of any (a) any actual or threatened release
     of any Hazardous Substance on, under, or about the Premises or the Building
     or (b) any injury, investigation, proceeding, or claim by any government
     agency or other person regarding the presence of Hazardous Substance on,
     under, or about the Premises or the Building, that party shall give the
     other party written notice of the release or investigation immediately (or
     as soon as practical in case of an emergency) after learning of it and
     shall simultaneously furnish the other party copies of any claims, notices
     of violation, reports or other writings received by the party providing
     notice that concern the release or investigation.

(c)  Warranties. Lessor warrants and represents to Lessee that, to the best of
     Lessor's knowledge without independent investigation inquiry, as of the
     effective date of the Lease:

     (i)   There has been no release onto or under the Premises or the Building
           of any Hazardous Substance in violation of any Applicable
           Requirements;

     (ii)  The Building contains no PCBs, PCB contaminated electrical equipment,
           or asbestos containing materials which in its present condition poses
           a health hazard to Lessee's employees; and

     (iii) Landlord has received no notice that the Premises or the Building is
           in violation of any Applicable Requirements.

(d)  Lessee's Indemnification.  Lessee shall indemnify, protect, defend and hold
     Lessor, its agents, employees, lenders and ground lessor, if any, and the
     Premises, harmless from and against any and all damages, liabilities,
     judgments, costs, claims, liens, expenses, penalties, loss of permits and
     attorneys' and consultants' fees arising out of or involving any Hazardous
     Substance brought onto the Premises by or for Lessee or by anyone under
     Lessee's control.  Lessee's obligations under this Paragraph 6.2 (D.) shall
     include, but not be limited to, the effects of any combination or injury to
     person, property or the environment created or suffered by Lessee, and the
     cost of investigation (including consultants' and attorneys' fees in
     testing), removal and remediation, restoration and abatement thereof, or of
     any combination therein involved, and shall survive the expiration or
     earlier termination of this Lease.  No termination, cancellation or release
     agreement entered into by Lessor and Lessee shall release Lessee from its
     obligations under this Lease with respect to Hazardous Substances, unless
     specifically so agreed by Lessor in writing at the time of such agreement.

(e)  Lessor's Indemnification.  Lessor shall indemnify, protect, defend and hold
     Lessee, its agents, employees, lenders and subtenants, if any, harmless
     from and against any and all damages, liabilities, judgments, cost, claims,
     liens, expenses, penalties, loss of permits, and attorneys, and
     consultants' fees arising out of or involving any Hazardous Substance
     brought onto the Premises by or for Lessor or by anyone under Lessor's
     control.  Lessor's obligations under this paragraph 6.2(D.) shall include,
     but not be limited to, the effects of any combination or injury to person,
     property or the environment created or suffered by Lessor, and the cost of
     investigation (including consultants' and attorneys' fees in testing),
     removal and remediation, gestation and abatement thereof, or of any
     combination therein involved, and shall survive the expiration of earlier
     termination of this Lease.  No termination, cancellation or release
     agreement entered into by Lessor and Lessee shall release Lessor from its
     obligations under the Lease with respect to Hazardous Substances, unless
     specifically so agreed by Lessee in writing at the time of such agreement.

(f)  Lessor's Consent to Reportable Uses.  Notwithstanding any contrary
     provision of this Lease, Lessor hereby consents to the installation or use
     of any above ground storage tank for the generation, possession, storage,
     loss, transportation, or disposal of, in, on or about the Premises, of the
     substances described in Exhibit B hereto, together with any additional
     Hazardous Substance, provided Lessee does not generate, possess, store,
     use, transport or dispose of more than fifty five gallons of each such
     additional Hazardous Substance.

as defined in subsection 8.7.2, from any cause arising out of or relating 
(directly or indirectly) to this Lease, the tenancy created under this Lease,

     building by Lessee Parties;

                                       2
<PAGE>

(b)  Any act, error, omission, or negligence of Lessee in, on, or about the
     Premises;

(c)  Lessee's conducting of its business;

(d)  Any alterations, activities, work, or things done, omitted, or permitted by

     standards, rules, regulations, orders, decrees, or judgments in existence
     on the Lease Commencement Date or enacted, promulgated, or issued after the
     date of this Lease, except to the extent that compliance with such legal
     requirements is made the responsibility of Landlord pursuant to this Lease;
     and 

(e)  Any breach or default in performance of any obligation on Lessee's part to
     be performed under this Lease.

8.7.2.     Definition of Claims.  For purposes of the Lease, "Claims" means

otherwise), charges, assessments, fines, and penalties of any kind (including 
consultant and expert expenses, court costs, and attorneys' fees actually 
incurred).

includes Claims for:

(a)  Injury to any persons (including death at any time resulting from that
     injury);

     all loss of use resulting from that loss, injury, damage, or destruction);

(c)  Economic losses and consequential or resulting damage, but only to the
     extent incurred by Landlord in connection with (1) a holdover of the
     Premises by Lessee after the expiration or earlier termination of this
     Lease or (2) any repair, physical construction, or work of improvement
     performed by or on behalf of Lessee in the Building.

8.7.4.     Indemnification Negligence and Willful Misconduct; Consequential 
Damages.  Despite any other provision of this Lease:

(a)  Lessee's indemnification in subsection 8.7.1 shall not apply to any claim
     caused by or arising out of the active or passive negligence of Landlord or
     to the extent that a Claim against Landlord actually or allegedly arises
     out of the willful misconduct of Landlord, except for damage to the Lessee
     Improvements or Lessee's personal property, fixtures, furniture, and
     equipment in the Premises to the extent that such damage is covered by
     insurance that Lessee is required to carry under this Lease (or would have
     been covered had Lessee carried the insurance required under this Lease);
     and

(b)  Except as provided in subsection 8.7.3:

     (1)   Nothing in this Lease shall impose any obligation on Landlord to be

           liability for, consequential damages suffered by Landlord.

8.7.5      Relationship of Indemnity to Other Lease Obligations. Lessees' 
agreement to indemnify Landlord and landlords' agreement to indemnify Lessee 
under this section 8.7 are not intended to and shall not:

     obligations under this Lease, such indemnity covenants being independent of
     the parties' insurance and other obligations; 

(b)  Be restricted, limited, or modified by the parties' compliance with their
     respective insurance requirements and other obligations under this Lease;

(c)  Relieve any insurance carrier of its obligations under policies required to
     be carried under this Lease to the extent that such policies cover, or if
     carried would have covered, the matters subject to the parties' respective
     indemnification obligations; or

(d)  Supersede any inconsistent agreement of the parties set forth in any other
     provision of this Lease.

8.7.6.     Attorney Fees.  The prevailing party shall be entitled to recover 
its actual attorney fees and court costs incurred in enforcing the 
indemnification clauses set forth in this section 8.7.3.

                                       3
<PAGE>

8.7.7.     Survival of Indemnification.  The clauses of this section 8.7 
shall survive the expiration or earlier termination of this Lease for a 
period of three (3) years but only to the extent that the Claims are covered 
and actually paid by the indemnifying party's insurance coverage.

8.7.8.     Landlord's Indemnification of Lessee.  Because Landlord is 
required to maintain insurance on the Building and because of the waivers of 
subrogation in this Lease, Landlord shall, with counsel reasonably acceptable 
to Lessee, indemnify, defend, and hold harmless Lessee from and against all 
Claims for damage to property outside the Premises to the extent that such 
Claims are covered by such insurance (or would have been covered had Landlord 
carried the insurance required under this Lease), even if resulting from the 
negligent acts, omissions, or willful misconduct of Lessee.  In addition, 
Landlord shall, with counsel reasonably acceptable to Lessee, indemnify, 
defend, and hold harmless Lessee from and against all Claims resulting from 
the negligent acts, omissions, or willful misconduct of Landlord in 
connection with Landlord's activities in, on, or about the Premises or 
Building, except to the extent that such claim is for damage to the Lessee 
Improvements and Lessee's personal property, fixtures, furniture, and 
equipment on the Premises and is covered by insurance that Lessee is required 
to obtain under this Lease (or would have been covered had Lessee carried the 
insurance required under this Lease).

           a.  On (Fill in COLA Date): December 1, 2000 (32nd month)  63rd and

     (Check Method(s) to be Used and Fill in Appropriately)

/X/  I.   COST OF LIVING ADJUSTMENT(s) (COL)

(a)  On (Fill in COL Date): See Addendum Paragraph 7 the monthly rent payable 
under paragraph 1.5 ("Base Rent") of the attached Lease shall be adjusted by 
the change,, if any, from the Base Month specified below, in the Consumer 
Price Index of the Bureau of Labor Statistics of the U.S. Department of Labor 
for (select one): /X/ CPI W (Urban Wage Earners and Clerical Workers) or  / / 
CPI U (All Urban Consumers), for (Fill in Urban Area): 
____________________________.  All terms (1982-1984 = 100), herein referred 
to as "CPI".

          (b)  This monthly rent payable in accordance with paragraph A.I.(a) of
this Addendum shall be calculated as follows:  the Base Rent set forth in
paragraph 1.5 of the attached Lease, shall be multiplied by a fraction the
numerator of which shall be the CPI of the calendar month 2 (two) months prior
to the month(s) specified in paragraph A.I.(a) above during which the adjustment
is to take effect, and the denominator of which shall be the CPI of the calendar
month which is 2 (two) months prior to (select one): / / the first month of the
term of this Lease as set forth in paragraph 1.3 ("Base Month") or / / (Fill in
Other "Base Month"):_______________.  The sum so calculated shall constitute the
new monthly rent hereunder, but in no event, shall any such new monthly rent be
less than the rent payable for the month immediately preceding the rent
adjustment.

          (c)  In the event the compilation and/or publication of the CPI shall
be transferred to any other governmental department or bureau or agency or shall
be discontinued, then the index most nearly the same as the CPI shall be used to
make such calculation.  In the event that the Lessor and Lessee cannot agree on
such alternative index, then the matter shall be submitted for decision to the
American Arbitration Association in accordance with the then rules of said
Association and the decision of the arbitrators shall be binding upon the
parties.  The cost of said Arbitration shall be paid equally by the Lessor and
Lessee.

                            MANAGEMENT SERVICES AGREEMENT

     This Management Services Agreement ("Agreement") is entered into as of 
June 18, 1998, between Burke Industries, Inc., a California corporation 
("Burke"), and J.F. Lehman & Company, a Delaware corporation ("JFL").  In 
consideration of the premises, it is agreed as follows:

     1.   BACKGROUND AND PURPOSE.

          1.1  Burke is engaged in the business, INTER ALIA, of designing, 
manufacturing, and marketing numerous types of rubber related products for 
both commercial and military applications.  Burke conducts such business 
operations worldwide, but is focused primarily in the United States.

          1.2  Key personnel of JFL have substantial expertise that is useful 
to Burke.  Burke desires to obtain management services from JFL, and JFL 
desires to provide management services to Burke, all on the terms and 
conditions of this Agreement. 

     2.   AGREEMENT TO PROVIDE MANAGEMENT SERVICES.  JFL hereby agrees to 
provide to Burke and at Burke's request the management services ("Services") 
listed in Schedule "A" attached hereto and hereby made a part hereof.  JFL's 
key personnel will devote as much of their business time and effort to the 
provision of Services hereunder as is reasonably required for the prompt and 
efficient accomplishment of the Services to be provided, and will not, except 
with Burke's express consent, accept undertakings for other clients that are 
likely to interfere or conflict with their availability to perform Services 
when required hereunder.  JFL agrees further to comply with the reasonable 
directions of Burke and to use its best efforts to promote Burke's interests.

     3.   MANAGEMENT FEES.  In consideration for the advisory and consulting 
services to be rendered by JFL to Burke hereunder, including services in 
connection with strategic financial planning, investment management, 
management and administration and other matters relating to the business and 
operations of Burke, Burke shall pay to JFL a fee (the "Annual Fee") in the 
amount of $500,000 per annum for each year during the period commencing on 
October 1, 1998 and ending on the date of the termination this Agreement.  
The Annual Fee shall be payable in quarterly installments, payable in advance 
beginning on October 1, 1998 and on the same calendar day of every third 
month thereafter until the date of termination of this Agreement.

     4.   EXPENSES.  Burke shall reimburse JFL promptly upon request for 
travel and other out-of-pocket expenses reasonably incurred in connection 
with the performance of Services pursuant to this Agreement, subject to the 
provision by JFL of satisfactory documentation of such expenses.  Salaries of 
JFL employees and the ordinary expenses of maintaining JFL's offices are not 
reimbursable expenses pursuant to this Agreement.

                                       1
<PAGE>

     5.   STATUS.  It is the intention of the parties that JFL shall be an 
independent contractor pursuant to this Agreement, and that this Agreement 
shall not be construed to create or give rise to any partnership, agency or 
joint venture.

     6.   TERM AND TERMINATION.  This Agreement shall be effective as of 
August 20, 1997 and shall continue in effect until the earliest to occur of 
(i) the tenth anniversary of this Agreement and (ii) the closing of a sale to 
an entity which is not an "Affiliate" (as defined in Section 12b-2 of the 
Securities Exchange Act of 1934) of the Company or any of its existing 
shareholders on the date hereof of all or substantially all of the capital 
stock or assets of the Company.  The provisions of Section 4 and otherwise as 
the context so requires shall survive the termination of this Agreement.

     7.   REPRESENTATIONS AND WARRANTIES.  JFL represents and warrants that 
it is not a party to or bound by any agreement or contract or subject to any 
restrictions, particularly, but without limitation, in connection with any 
previous or other consulting relationship, which prevents JFL from entering 
into and performing its obligations under this Agreement.

     8.   MISCELLANEOUS.  

          8.1  This Agreement contains the entire understanding of the 
parties with respect to the subject matter contained herein and may be 
altered, amended or superseded only by an Agreement in writing, signed by the 
party against whom enforcement of any waiver, change, modification, extension 
or discharge is sought.  This Agreement may be assigned by either party only 
with the written consent of the other.

          8.2  If any provision of this Agreement shall be prohibited or 
invalid under applicable law, such provision shall be ineffective only to the 
extent of such prohibition or invalidity without invalidating the remainder 
of such provision or the remaining provisions of this Agreement.

                 subject to any vesting schedule applicable to Supplemental

                 existence of such book entries and the Retirement Account
                 shall not create and shall not be deemed to create a trust of
                 any kind, or a fiduciary relationship between the Corporation
                 and the Employee, his designated beneficiaries or other

2.   DEFERRED COMPENSATION.

a.   Employee Deferrals.

Commencing on the Effective Date, and continuing through the date on which the
Employee's employment terminates because of his death, retirement, disability,
or any other cause, the Employee and the Corporation agree that the Employee
shall defer into his Retirement Account the amount set forth in the Election of
Deferral, which the Employee would otherwise be entitled to receive from the
Corporation in each Fiscal Year of the Corporation.

The amount selected for deferral by the Employee pursuant to an Election of
Deferral is referred to as the "Annual Deferral Sum."  The amounts of
compensation actually deferred, taking into account discontinuance of deferral
pursuant to a Notice of Discontinuance, are hereinafter collectively referred to
as the "Deferred Amounts."  The Employee's Deferred Amounts shall be credited to
the Employee's Retirement Account as of the dates such Deferred Amounts would,
but for such deferral, be payable to the Employee.

3.   ADDITIONS TO DEFERRED AMOUNTS.  The Corporation agrees that it will credit
     Deferred Amounts in the Employee's Retirement Account with additions
     thereon ("Additions") from and after dates Deferred Amounts are credited to
     the Retirement Account.  Additions to Deferred Amounts shall accrue
     commencing on the date the Retirement Account first has a positive balance
     and shall continue up to the date that the 

                                       3

<PAGE>

     Retirement Account has been reduced to zero.  Additions shall be calculated
     as an amount (the "As If Rate") equal to the yield that would be realized,
     including any dividends, interest, or other current yield, as well as any 
     capital gain or loss based on an adjustment to fair market value on any 
     date of calculation, as if hypothetically invested in whole or fractional 
     shares in the assets set forth at Schedule 2 (the Calculation Assets), 
     which may be changed at the sole discretion of the Employer, from time to 
     time.  The Employer shall have no obligation to actually acquire any of 
     the Calculation Assets set forth at Schedule 2, and such return shall be
     only for purposes of calculating Additions to Deferred Amounts hereunder.
     The Employee shall have no rights in or to any Calculation Assets set forth
     at Schedule 2, as provided elsewhere in this Agreement.  The As If Rate 
     shall be adjusted on the last day of each fiscal quarter the plan year at 
     the mean trading price of the Calculation Assets on such date or the first
     business date thereafter, as quoted in Barrons financial news publication,
     or in the absence of a quotation therein, in a similar publication or other
     authoritative valuation of the specified Calculation Assets.  Any such
     designation of new Calculation Assets by the Employer must be in writing. 
     For purposes of calculating Additions, it shall be assumed that the
     Calculation Assets is sold and the alternate Calculation Assets is
     purchased on the first business day following such revised designation by
     the Corporation.

4.   ELECTION TO DEFER COMPENSATION.  The Employee may elect an Annual Deferral
     Sum hereunder by filing an Election of Deferral.  The initial Election of
     Deferral must be filed within twenty (20) days of the Effective Date of
     this Agreement.  Such initial Election of Deferral, if any, shall be
     effective commencing with the first day of the month after it is filed. 
     Thereafter, an Election of Deferral must be filed at least twenty (20) days
     prior to the beginning of the Plan Year to which it pertains and shall be
     effective on the first day of the Plan Year following the filing thereof. 
     The maximum amount of the Annual Deferral Sum shall be an amount equal to
     the maximum amount that can be deferred under section 402(g), which limits
     deferrals under qualified cash or deferred arrangement, which amount is
     equal to $7000 adjusted annually so that for 1995 the limitation hereunder,
     for example, is $9240.  The minimum deferral shall be One Thousand Dollars
     ($1,000).

5.   TERMINATION OF ELECTION.  The Employee's initial Election of Deferral shall
     continue in effect, pursuant to the terms of the Election of Deferral,
     unless and until the Employee files with the Corporation a Notice of
     Discontinuance or a subsequent Election of Deferral specifying a different
     amount of deferral.  Each Election of Deferral filed subsequent to the
     initial Election of Deferral shall similarly continue in effect until the
     Employee files a Notice of Discontinuance or a new Election of Deferral. 
     Any new Election of Deferral, to be effective, must be filed at least
     twenty (20) days prior to the beginning of the Plan Year in which deferral
     is sought.  A notice of Discontinuance shall be effective if filed at least
     twenty (20) days prior to any 1st day of the first month, 1st day of the
     fourth month, 1st day of the seventh month, or 1st day of the tenth month
     of the Plan Year.  Such Notice of Discontinuance shall be effective
     commencing with the 1st day of the first month, 1st day of the fourth
     month, 1st day of the seventh month, or 1st day of the tenth month of the
     Plan Year following its filing, whichever applies, and 

                                       4

<PAGE>

     shall apply only with respect to the Employee's Compensation attributable 
     to services not yet performed.

6.         (a)  RETIREMENT BENEFIT.  The Corporation agrees that, from and
           after the retirement of the Employee from the service of the
           Corporation upon reaching his Early Retirement Date or Normal
           Retirement Date, the Corporation shall thereafter pay as a
           retirement benefit ("Retirement Benefit") to the Employee the
           Employee's entire Accrued Benefit in equal monthly installments for
           one hundred twenty  (120) consecutive months, commencing on the
           first day of the second calendar month immediately following the
           Employee's retirement; provided, however, that the Employee may, at
           his sole option make one election prior to the time benefit payments
           begin to receive the Accrued Benefit in his Retirement Account in
           equal monthly installment payments over a shorter period, to be
           designated by him in writing, than would otherwise apply, or in a
           single payment.  The election referred to in the preceding sentence
           must be made at least on hundred eighty (180) days prior to the date
           benefit payments begin and shall be irrevocable.  In the event of
           such election by the Employee, the first designated monthly payment
           or the single payment, whichever applies, shall be due and payable
           on the first day of the second month following the Employee's filing
           of an effective written election to accelerate benefits. Monthly
           installment payments, if applicable, shall continue monthly
           thereafter, for the period designated by the Employee.

     (b)   ELECTION OF BENEFITS UPON RETIREMENT DATE.  The Employee shall have
           the option, upon attaining his Early Retirement Date or Normal
           Retirement Date, to elect to receive his Retirement Benefit,
           notwithstanding his continued employment with the Corporation after
           he has attained his Early Retirement Date or Normal Retirement Date. 
           The Employee's election to receive his Retirement Benefit
           notwithstanding his continued employment must be made in writing at
           least sixty (60) days prior to his Early Retirement Date or Normal
           Retirement Date, whichever applies.  The Retirement Benefit payable
           upon election pursuant to this paragraph 6.b. shall be the amount
           that would have been payable had the Employee retired from service
           with the Corporation as of his Early Retirement Date or Normal
           Retirement Date, whichever applies.  Any such election shall be
           irrevocable, and shall result in the termination of the Employee's
           right to any further deferrals hereunder.

7.   DISABILITY RETIREMENT.  Notwithstanding any other provision hereof, the
     Employee shall be entitled to receive payments hereunder prior to his Early
     Retirement Date or Normal Retirement Date, whichever applies, in any case
     in which it is determined by a duly licensed physician selected by the
     Corporation that, because of ill health, accident, disability or general
     inability because of age, the Employee is no longer able, properly and
     satisfactorily, to perform his regular duties as an Employee.  In the event
     that the Employee's employment is terminated, then, pursuant to this
     paragraph 7, the disability retirement benefit payable hereunder
     ("Disability Retirement Benefit") shall be 

                                       5

<PAGE>

     that amount that would have been payable as a Retirement Benefit had the 
     Employee attained his Normal Retirement Date on the date of the physician's
     disability determination. The Disability Retirement Benefit payable under 
     this paragraph 7 shall be distributed in accordance with the provisions of
     paragraph 6.a. as if the Employee had retired on the date of the 
     physician's disability determination. 

8.         (a)   DEATH BENEFIT PRIOR TO COMMENCEMENT OF RETIREMENT BENEFITS. 
           In the event of the Employee's death while in the employment of the
           Corporation and prior to commencement of the Retirement Benefits or
           Disability Retirement Benefits, the Corporation shall pay as a
           survivor's benefit the Employee's entire Survivor Benefit in a
           single lump sum to the Employee's designated beneficiary (the
           "Beneficiary"), in accordance with the last such designation
           received by the Corporation from the Employee prior to death.  If no
           such designation has been received by the Corporation from the
           Employee prior to death or if said payment is not otherwise to be
           made as provided herein, said payment shall be made to the
           Employee's then living spouse, so long as such surviving spouse
           shall live and thereafter to such person or persons, including the
           estate of the spouse, as the spouse may appoint by Will, making
           specific reference hereto; if the Employee is not survived by a
           spouse or if the spouse shall fail to do so appoint, then said
           payment shall be made to the then living children of the Employee,
           if any, in equal shares, for their joint and survivor lives; and if
           none or after their respective joint and survivor lives, in one lump
           sum to the estate of the Employee.  Such payment shall commence on
           the first day of the second month following the Employee's death.

     (b)   DEATH BENEFIT AFTER COMMENCEMENT OF BENEFITS.  In the event of the
           Employee's death after commencement of Retirement benefits, Normal
           Retirement Benefits, or Disability Retirement Benefits, but prior to
           the completion of all such payments due and owing hereunder, the
           Corporation shall pay the balance of the Accrued Benefit in a single
           lump sum the Employee's designated beneficiary, in accordance with
           the last such designation received by the Corporation form the
           Employee prior to his death.  If no such designation has been
           received by the Corporation from the Employee prior to his death or
           if said payments are not otherwise to be made as provided herein,
           said payments shall be made to the Employee's then living spouse, so
           long as she shall live and thereafter to such person or persons,
           including his estate, as he may appoint under his Will, or other
           testamentary instrument, making specific referenced hereto; if the
           Employee is not survived by a spouse or if he shall fail to so
           appoint, then said payments shall be made to the then living
           children of the Employee, if any, in equal shares, for their joint
           and survivor lives; and if none or after their respective joint and
           survivor lives, any balance thereof in one lump sum to the estate of
           the Employee.  Such payments shall commence on the first day of the
           first month following the Employee's death.  At its sole option, the
           Corporation may pay the Employee's entire Accrued Benefit as a
           single lump sum.

                                       6

<PAGE>

9.   TERMINATION BENEFIT.  In the event the Employee's termination of employment
     with the Corporation before his Early Retirement Date or Normal Retirement
     Date for any reason, other than disability, retirement or death, the
     Corporation shall pay to the Employee, as compensation for services
     rendered prior to such termination, a single sum equal to the total
     Deferred Amounts hereunder, including any Additions thereto (the
     "Termination Benefit"), subject to the vesting schedule described at
     paragraph 2 above.  The Termination Benefit shall be payable on the first
     day of the second month following the termination of the Employee's
     employment with the Corporation.

10.  HARDSHIP WITHDRAWAL.  In the event the Employee suffers from unforeseen
     financial emergency, as defined hereafter, the Corporation may, if it deems
     advisable in its sole and absolute discretion, distribute to or utilize on
     behalf of the Employee as a hardship benefit (the "Hardship Benefit") any
     portion of the Employee's Retirement Account.  The Corporation shall have
     exclusive authority to determine whether to make a hardship distribution,
     and the Corporation's decision shall be final and binding on all parties. 
     Any hardship distribution shall, like all distributions, reduce the amounts
     available for subsequent distributions and be deducted from the Retirement
     Account.  The Employee shall apply for such a Hardship Benefit in writing
     in a form approved by the Corporation and shall provide such additional
     information as the Corporation shall require.  For purposes of this
     Paragraph, "unforeseen financial emergency" means an immediate and heavy
     financial need caused by an unforeseeable emergency, as described in
     Treasury Regulations Section 1.457-2(h) (4) and (5), resulting from any of
     the following, and in an amount not in excess of the amount needed to pay
     for the following unreimbursed expenses:

     a.    expenses which are not covered by insurance and which the Employee
           or his or her spouse or dependents (as defined in Code Section
           152(a)) has incurred as a result of, or is required to incur in
           order to receive, medical care described in Code Section 213(d), as
           a result of a sudden or unexpected illness;

     b.    loss of an employee's property as a result of casualty, or,

     c.    other similar extraordinary, unforeseeable circumstances
           attributable to forces beyond the Employee's control.

           No distribution shall be made pursuant to this paragraph in excess
           of the amount of the immediate and heavy financial need of the
           Participant.  The amount of the immediate and heavy financial need
           may include any amounts necessary to pay federal, state or local

11.  QUALIFIED PLAN ELECTION.  As soon as practicable each Plan Year of the
     Qualified Plan and not later than January 31 of the next ensuing year, the
     Employer shall perform a preliminary actual deferral percentage and actual
     contribution percentage testing to determine the maximum amount of
     additional elective contributions that could be made to the Qualified Plan
     for the current Plan Year, consistent with Code section 402(g) and the
     limitations of section 401(k)(3), on behalf of Employee as a participant in

                                       7

<PAGE>

     the Qualified Plan.  The lesser of those amounts, or the Employee's salary
     deferral for the Plan Year as set forth at the Deferral Election Form at
     Exhibit A for the Plan Year, will be paid to the Employee as soon as
     practicable, but in no event later than March 15 of the Plan Year following
     the Plan Year for which such determination is made, unless the Employee
     previously elected to have such amount contributed to the Qualified Plan as
     an elective contribution.  The Employee's election to have such amount
     contributed to the Qualified Plan must be made at the same time as the
     Election of Deferral under this Agreement, which must in no event be later
     than the December 31 of the calendar year in which the compensation to
     which the salary deferral relates is earned and, once made, the election
     shall be irrevocable.  If the Employee so elects, the Employer shall cause
     the elected amount to be contributed directly to the Qualified Plan in
     accordance with this paragraph.  In no event will any earnings under this
     Plan be credited to the Qualified Plan.

12.  BENEFICIARY DESIGNATION.  The Employee shall have the right, at any time to
     submit in substantially the form attached hereto as Exhibit B, a written
     designation of primary and secondary beneficiaries to whom payment under
     this Agreement shall be made in the event of his death prior to complete
     distribution of the benefits due and payable under the Agreement.  Each
     beneficiary designation shall become effective only when receipt thereof is
     acknowledged in writing by the Corporation.

13.  DETERMINATION OF BENEFITS.

a.   Claim

     A person who believes that he is being denied a benefit under the Plan
     (hereinafter referred to as a "Claimant") may file a written request for
     such benefit with the Corporation, setting forth his claim.  The request
     must be addressed to the Treasurer of the Corporation at its then principal
     place of business.

b.   Claim Decision.

     Upon receipt of a claim, the Corporation shall advise the Claimant that a
     reply will be forthcoming within ninety (90) days and shall, in fact,
     deliver such reply within such period.  The Corporation may, however,
     extend the reply period for an additional ninety  (90) days for reasonable
     cause.

     If the claim is wholly or partially denied, the Corporation shall provide a
     written notice within ninety  (90) days specifying the reason for the
     denial, the plan provisions on which the denial is based, and additional
     material or information necessary to receive benefits, if any, and why such
     material or information is necessary. Also, such written notice shall
     indicate the steps to be taken if a review of the denial is desired.

c.   Request for Review.

                                       8

<PAGE>

     If a claim is denied and a review is desired, the Employee (or designated
     beneficiary in the case of the Employee's death) shall notify the
     Corporation in writing within sixty (60) days after receipt of a written
     notice of a denial of a claim.  In requesting a review the Employee may,
     but need not, review the pertinent documents and submit issues and comments
     in writing for consideration of the corporation and refer to plan
     documents.

d.   Review of Decision.

     The Corporation shall then review the claim and provide a written decision
     within sixty (60) days of receipt of a request for review.  This decision
     shall state the specific reasons for the decision and shall include
     references to specific provisions on which the decision is based.  If
     special circumstances require that the sixty (60) day time period be
     extended, the Corporation will so notify the Claimant and will render the
     decision as soon as possible, but no later than one hundred twenty (120)
     days after receipt of the request for review.

14.  BENEFITS NOT TRANSFERABLE.  Neither the Employee nor any designated
     beneficiary shall have any right to transfer, assign, anticipate,
     hypothecate or otherwise encumber any part or all of the amounts payable
     hereunder.  No such amounts shall be subject to seizure by any creditor of
     such beneficiary, by a proceeding in law or equity, nor shall such amounts
     be transferable by operation of law in the event of bankruptcy, insolvency
     or death of the Employee, his designated beneficiary, or any other
     beneficiary hereunder.  Any such attempted transfer shall be void.

15.  NO CONTRACT OF EMPLOYMENT.  Nothing contained herein shall be construed to
     be a contract of employment for any term of years, not as conferring upon
     the Employee the right to continue to be employed by the Corporation, in
     any capacity.  It is expressly understood by the parties hereto that this
     Agreement relates exclusively to deferral of otherwise currently payable
     compensation for the Employee's services; such deferral to be payable after
     termination of Employee's employment with the Corporation, or as otherwise
     provided.  This Agreement is not intended to be an employment contract.

16.  CONSTRUCTION OF AGREEMENT.  Any payments under this Agreement shall be
     independent of, and in addition to, those under any other plan, program, or
     agreement which may be in effect between the parties hereto, or any other
     compensation payable to the Employee or the Employee's designated
     beneficiary by the Corporation.

17.  NO TRUST CREATED.  Nothing contained in this Agreement, and no action taken
     pursuant to its provisions by either party hereto, shall crate nor be
     construed to create, a trust or any kind of a fiduciary relationship
     between the Corporation and the Employee, the Employee's designated
     beneficiary, any other beneficiary of the Employee or any other person. 

18.  BENEFITS PAYABLE ONLY FROM GENERAL CORPORATE ASSETS; UNSECURED GENERAL
     CREDITORS STATUS OF EMPLOYEE.  The payments to the Employee, the Employee's
     designated beneficiary or any other beneficiary hereunder 

                                       9

<PAGE>

     shall be made from assets which shall continue, for all purposes, to be a 
     part of the general, unrestricted assets of the Corporation; no person 
     shall have nor acquire any interest in any such assets by virtue of the 
     provisions of this Agreement.  The Corporation's obligation hereunder shall
     be an unfunded and unsecured promise to pay money in the future.  To the 
     extent that the Employee or any person acquires a right to receive payments
     from the Corporation under the provisions hereof, such right shall be no 
     greater than the right of any unsecured general creditor of the 
     Corporation, no such person shall have nor require any legal or equitable 
     right, interest or claim in or to any property or assets of the 
     Corporation.

     In the event that, in its sole discretion, the Corporation purchases an
     insurance policy or policies insuring the life of the Employee (or any
     other property) to allow the Corporation to recover the cost of providing
     the benefits, in whole, or in part, hereunder, neither the Employee, the
     Employee's designated beneficiary, any other beneficiary nor any other
     person shall have nor acquire any rights whatsoever therein or in the
     proceeds therefrom.  The Corporation shall be the sole owner and
     beneficiary of any such policy or policies and, as such, shall possess and,
     may exercise all incidents of ownership therein.  No such policy, policies
     or other property shall be held in any trust for the Employee or any other
     person nor as collateral security for any obligation of the Corporation
     hereunder.

19.  AMENDMENT.  This Agreement may not be altered, amended, or revoked except
     by a written agreement signed by the Corporation and Employee.

20.  INTERPRETATION.  Where appropriate in this Agreement, words used in the
     singular shall include the plural and words used in the masculine shall
     include the feminine.

21.  ARBITRATION.  All disputes, controversies or differences arising out of, or
     in relation to or in connection with this Agreement, which cannot be 
     settled by discussion and mutual accord, shall be resolved exclusively 
     by binding arbitration in the country in which the principal office of 
     the Employer is located in accordance with the then prevailing 
     Commercial Arbitration Rules of the American Arbitration Association.  
     Demand for arbitration shall be made in writing and shall be served upon 
     the party or parties to whom the demand is addressed in the manner 
     provided at paragraph 22 below.  If the parties are unable to mutually 
     agree on an arbitrator within twenty (20) days after delivery of the 
     request for arbitration, each shall have the right to petition an 
     appropriate court that would have jurisdiction over this matter in the 
     country in which the principle office of the Employer is located, to 
     appoint an arbitrator with experience in manners of executive 
     compensation law and business practice.  Unless otherwise agreed in 
     writing by the parties, they shall make their initial submissions to the 
     arbitrator(s) and the arbitration hearing shall commence within thirty 
     (30) days of the agreement on or appointment of the arbitrator. The 
     arbitration hearing shall be completed within thirty (30) days 
     thereafter. The award shall be made promptly by the arbitrator(s) and, 
     unless otherwise agreed by the parties, no later than thirty (30) days 
     after the completion of the hearing; provided however, that any failure 
     to render the award within such time shall not affect the validity of 
     such award.  The award rendered by the arbitrator(s) shall set forth 
     his/her findings of the facts and conclusions of law and shall be final, 
     and judgment upon the award rendered may be entered in 

                                      10

     for a judicial acceptance of the award and an order of enforcement, as 
     the case may be. In that regard, each of the parties to this Agreement 
     hereby submits to the jurisdiction of the courts of the State of 
     California, and to the federal courts of the United States of America 
     located in the county in which the principle office of the Employer is 
     located.

22.  TERMINATION OF PLAN.  The Employer may at any time during the term of this
     Agreement, file a Notice of Termination with the Employee thereby
     terminating this Plan as of the first day of the subsequent month.  If the
     Employer elects to terminate this Agreement, the Employee shall be entitled
     to receive the amounts computed as provided in Section (9) hereinabove,
     provided however, that in the event of a termination of the Plan by the
     Employer, there shall be no reduction of the Retirement Account as a result
     of any vesting schedule otherwise applicable to Supplemental Deferrals.

23.  OFFSET FOR OBLIGATIONS TO CORPORATION.  If, at such time as the Employee
     becomes entitled to benefit payments hereunder, the Employee has any debt,
     obligation or other liability representing and amount owing to the
     corporation or an affiliate of the corporation, and if such debt,
     obligation or other liability is due and owning at the time benefit
     payments are payable hereunder, the corporation  may offset the amount
     owning it or an affiliate against the amount of benefits otherwise
     distributable hereunder.

     (b)   This Agreement may be executed in one or more counterparts, each of

           by a court of competent jurisdiction to be invalid, illegal, or
           unenforceable for any reason, such provision shall be modified or
           deleted in such a manner so as to make the Agreement as modified
           valid, legal and enforceable, and the balance of the Agreement shall
           not be affected thereby.

     (d)   Any notice required or permitted hereunder shall be given to the
           appropriate party at the address specified beneath such party's

may accelerate the exercise date of part or all of any Option.

           5.7    TRANSFERABILITY.  Each Option, by its terms, shall not be

Code) and the excise tax on such payment would cause the net parachute payments
(after taking into account federal, state and local income and excise taxes) to
which the Employee otherwise would be entitled to be less than what the Employee
would have netted (after taking into account federal, state and local income
taxes) had the present value of the Employee's total parachute payments equaled
One Dollar ($1.00) less than three (3) times the Employee's "base amount"
(within the meaning of Code Section 280(G)(b)(3)(A)), the Employee's total
"parachute payments" (within the meaning of Code Section 280G(b)(2)(A)) shall be
reduced (by the minimum possible amount) so that their aggregate present value
equals One Dollar ($1.00) less than three (2) times such base amount.  For
purposes of this calculation, it shall be assumed that the Employee's tax rate
will be the maximum marginal federal, State and 

                                       4

<PAGE>

local income tax rate on earned income, with such maximum federal rate to be 
computed with regard to Code Section 1(g), if applicable.  In the event that 
the Employee and the Company are unable to agree as to the amount of the 
reduction described above, if any, the Employee shall select a law firm or 
accounting firm from among those regularly consulted (during the twelve (12) 
month period immediately prior to the change in control that resulted in the 
characterization of the payments as parachute payments) by the Company 
regarding federal income tax or employee benefit matters, and such law firm 
or accounting firm shall determine the amount of much reduction and such 
determination shall be final and binding upon the Employee and the Company.
