ITEM 1.  BUSINESS
 
OVERVIEW
 
    Portola Packaging, Inc. (together with its subsidiaries referred to
hereinafter as the "Company" or "Portola") is a leading designer, manufacturer
and marketer of tamper evident plastic closures and related equipment used for
packaging applications in dairy, fruit juice, bottled water, sports drinks,
institutional food products and other non-carbonated beverage products. The
Company's principal closure product lines include (i) small closures, (ii) five
gallon closures, (iii) widemouth closures, (iv) fitments and (v) push-pull
dispensing closures. Portola also designs, manufactures and supplies high speed
capping equipment and complete turnkey water bottling systems, which are
marketed by the Company primarily under the tradename "PortaPlant". Portola's
closure products are primarily manufactured domestically through a
technologically advanced, high speed injection molding process at eight modern
manufacturing facilities strategically located throughout the United States,
three facilities located in Canada and one facility located in the United
Kingdom. Management believes that the Company is a leader in a majority of the
markets it serves and that the Company is the sole or largest supplier of
plastic closures for a majority of its customers. The Company sells over 10.8
billion closures annually under the names Cap Snap, Nepco, Portola and other
brand names to over 3,000 customers. Most of the Company's customers have been
doing business with the Company for more than ten years. The Company's products
are used to cap such well known consumer products as Borden milk, Dole juices,
Poland Spring bottled water, Pepsi-Cola fountain syrups and Kraft barbecue
sauce. Many features of the Company's closure products are proprietary, and
Portola holds more than 70 patents on the design of container closures and
compatible bottle necks.
 
    During the past decade, the plastic closure market has grown faster than the
overall closure market in the United States. This growth is primarily due to
certain advantages that plastic closures have over metal closures, including
greater performance and design flexibility, the growing demand for tamper
evident packaging and the comparatively lower cost and lighter weight of plastic
closures, an important factor in the packaging industry, where transportation
costs are a significant portion of overall product costs. Demand for plastic
closures has also grown with the increased use of plastic containers and the
conversion of paperboard containers to plastic containers.
 
HISTORY
 
    The Company was incorporated in California in 1964, and reincorporated in
Delaware in June 1994. The Company (formerly known as Cap Snap Seal, Inc.) was
acquired from the founding family in 1986 by a group led by Jack L. Watts, the
Company's current Chairman of the Board and Chief Executive Officer. Since
Portola was acquired from the founding family, the size of the Company as
measured by sales and closure unit volume has increased from $26.1 million in
sales and 2.1 billion in closure units sold for fiscal 1987 to $170.4 million in
sales and 10.8 billion in closure units sold for fiscal 1997. Portola's senior
management has significant experience in the plastic packaging business and an
average tenure of seven years at the Company. The Company's executive offices
are located at 890 Faulstich Court, San Jose, California 95112, and its
telephone number is (408) 453-8840.
 
BUSINESS STRATEGY
 
    The Company's primary strategy is to increase cash flow by maintaining and
extending its leading position in niche product applications within the plastic
closure and bottling industry. To support this strategy, the Company focuses on
(i) investing in advanced research and development and product engineering, (ii)
providing dedicated customer support and total product solutions for customers,
(iii) continuing to improve production efficiencies and enhance low cost
manufacturing capabilities,
 
                                       2
<PAGE>
(iv) expanding sales in international markets where significant growth
opportunities exist and (v) where appropriate, seeking strategic acquisitions
that will strengthen the Company's competitive position.
 
    EMPHASIZING RESEARCH AND DEVELOPMENT AND PRODUCT ENGINEERING.  The Company
is continuing its commitment to research and development, a commitment that has
led to significant product innovations. These innovations include the original
snap cap design and the five gallon closure, the "tear strip" feature that has
become a standard tamper evident mechanism for food and non-carbonated beverage
products and, an improved recloseable plastic dispensing fitment for gable-top
fruit juice and milk cartons and the snap-screw cap.
 
    EMPHASIZING CUSTOMER SUPPORT AND TOTAL PRODUCT SOLUTIONS.  The Company seeks
to preserve its long-term relationships with customers and attract new customers
by providing superior on-time delivery and technical service and support and by
marketing its products as "total product solutions." The total product solution
approach includes seeking at all times to provide plastic closures designed to
meet customer specifications, compatible container necks and neck inserts,
capping and filling equipment and on-going service and support.
 
    CONTINUING TO ENHANCE LOW COST MANUFACTURING CAPABILITIES.  The Company's
operations emphasize minimizing production and raw materials purchasing costs.
The Company has a continuing productivity improvement program designed to
further automate its production flow, streamline its workforce and upgrade its
molds, equipment and systems. See "Raw Materials and Production."
 
    EXPANDING SALES IN INTERNATIONAL MARKETS.  The Company expects significant
growth in international markets for plastic closures and capping and filling
equipment, as bottled water and other non-carbonated water companies in Europe,
the Far East, Latin America and elsewhere adopt more advanced packaging
materials and techniques. The Company is seeking to capitalize on the
opportunity for expansion into international markets through the formation of
joint ventures with local bottle manufacturers, bottlers, and distributors and
by increasing export sales of closures and capping and filling equipment. To
date, the Company has entered into a joint venture in Mexico and has acquired
its Canadian and United Kingdom subsidiaries. In addition, the Company signed a
joint venture agreement on November 14, 1997 with the Shanghai Aquarius Drinking
Water Company of Shanghai, China to produce and sell caps and bottles for the
Asian marketplace. The Company has no firm plans at this time for expansion into
other international markets although it will continue to evaluate other
expansion opportunities as they arise. See "International Sales and Joint
Ventures."
 
    SEEKING STRATEGIC ACQUISITIONS.  Portola plans to continue its program of
seeking to acquire businesses serving similar customers using proprietary
product and process technology that offer opportunities to improve costs or
extend the Company's product lines. Since fiscal 1994, the Company has acquired
Nepco, completed its Canadian and United Kingdom acquisitions, and entered into
joint ventures in Mexico and China.
 
    Consistent with the Company's objective to improve production efficiencies
and enhance low cost manufacturing capabilities, as well as quality, in the
second quarter of fiscal 1997, the Company adopted a restructuring plan designed
to streamline its organization by eliminating multiple reporting channels and
duplicative personnel in manufacturing and other functions, and to implement
other cost savings measures. The restructuring included a reduction in
management and other personnel positions and closure of its Portland, Oregon and
Bettendorf, Iowa manufacturing facilities. The Portland, Oregon facility was
recently sold and the Bettendorf, Iowa facility has been listed for sale. As
described under the heading entitled "Management's Discussion and Analysis of
Financial Condition and Results of Operations," the Company recorded a
restructuring charge during the year of $2.4 million and a write-off of
intangibles of $1.7 million.
 
    Consistent with the Company's objective to expand through strategic
acquisitions, on June 30, 1994, the Company acquired Northern Engineering &
Plastic Corp. and certain related companies and assets
 
                                       3
<PAGE>
(collectively, "Nepco") for a purchase price of $43.7 million. The acquisition
of Nepco, a designer, manufacturer and marketer of tamper evident plastic
closures in markets similar to those served by Portola, has enabled the Company
to establish new customer relationships, diversify and expand its product
offering and customer base and benefit from Nepco's proprietary product designs.
The Company has realized and expects to continue to achieve additional cost
savings and synergies associated with the integration of Nepco, primarily from
reduced costs achieved through sharing and adoption of improved technology and
manufacturing processes, lower raw material costs through volume purchasing
economies, marketing efficiencies and elimination of duplicative administrative
and financial staff positions. On June 16, 1995, the Company purchased for $13.6
million the 50% interest it had not previously owned in Canada Cap Snap
Corporation, a British Columbia corporation engaged in manufacturing and
distributing small closures in western Canada, together with all the capital
stock of two affiliated plastic bottle manufacturers (the "Western Canadian
Acquisition"). The companies acquired in the Western Canadian Acquisition were
amalgamated and now operate under the name "Portola Packaging Canada Ltd." On
September 1, 1996, the Company purchased for $2.1 million Rapid Plast J-P. Inc.,
a company headquarted in Montreal, Quebec (the "Eastern Canadian Acquisition").
Rapid Plast J-P. Inc. now operates under the name "Portola Packaging Ltd." and
is engaged in manufacturing and distributing plastic bottles, primarily in
eastern Canada. Management anticipates that the Canadian acquisitions will
enable the Company to establish a position in the Canadian bottle manufacturing
marketplace and to advance its position in the Canadian closure marketplace. On
September 1, 1995, the Company purchased for $1.5 million the 50% interest it
had not previously owned in Cap Snap (U.K.) Ltd., now known as "Portola
Packaging Limited" (the "U.K. Acquisition"). The Company recently leased a
manufacturing facility located in Doncaster, South Yorkshire, England which is
being used by Portola Packaging Ltd. to manufacture closures for distribution
primarily in the United Kingdom, with some exports to Europe.
 
PLASTIC CLOSURE MARKET
 
    Portola competes in the closure segment of the worldwide container packaging
industry, focusing specifically on proprietary tamper evident plastic closure
applications. Container closure devices have various applications with designs
engineered to meet specific use requirements. Major product applications for
container closures include food, beverages, toiletries, cosmetics, drugs and
pharmaceuticals.
 
    Closure design is a function of the type of container and its contents.
Products which are carbonated, perishable, highly acidic or susceptible to
tampering all require specialized capping applications. In many instances, it
may be necessary for the container to be resealable, or it may be preferable for
the contents to be dispensed through the closure without the closure being
removed. Subject to these and other packaging requirements, container closures
can be made from either plastic or metal.
 
    Demand for plastic closures has expanded with the increase in demand for
plastic containers. Over the past several years, rigid and flexible plastic
containers have experienced significant growth in market share at the expense of
other materials such as glass and metal. Plastic containers have several
advantages over glass and metal in that they are relatively inexpensive as well
as flexible and light weight, which are important factors in the
transportation-sensitive packaging industry.
 
    The use of plastic closures has grown with the trend toward tamper evident
packaging. A tamper evident feature is highly valued by the food and beverage
market and the pharmaceutical market, and tamper evident features are
experiencing growth in most segments of the closure market. While certain tamper
evident devices can be incorporated into metal closures, the most sophisticated
devices have been developed for plastic closures. Portola invented the original
snap-on cap design as well as the "tear strip" feature with breakaway bands for
plastic closures, which provided the standard tamper evidency mechanism for the
food and non-carbonated beverage industries.
 
    Historically, demand for the Company's products has been a function of
population growth, increasing concerns by the public about the sanitation of
packaged food and beverage products, and the continued
 
                                       4
<PAGE>
increase in the use of plastic containers, as opposed to glass or metal,
throughout the packaged food industry. For juice and bottled water markets,
demand is also a function of seasonal climate variations, warm weather being
responsible for increased consumption. See "Products" and "Product Development."
 
PRODUCTS
 
    Portola designs, manufactures and markets a wide array of tamper evident
plastic closures for applications in dairy, fruit juice, bottled water, sport
drinks, institutional food products and other non-carbonated beverage products.
The Company also designs, manufactures and markets (i) high speed capping
equipment for use by its plastic closure customers in their bottling and
packaging operations and (ii) customized bottling systems for returnable water
cooler bottles which it markets primarily under the name "PortaPlant." The
Company's sales of plastic closures represented approximately 89% of total sales
for each of the 1995 through 1997 fiscal years. In the most recent year, 1997,
the balance of sales were for equipment (8%) and bottles (3%).
 
    PLASTIC CLOSURES
 
    The Company's plastic closures are broadly grouped into five categories: (i)
small closures used to cap blowmolded plastic bottles, (ii) closures for five
gallon returnable glass and plastic water cooler bottles, (iii) widemouth
closures for institutional food products, (iv) fitments for gable-top containers
(such as conventional paperboard milk and juice cartons) and (v) push-pull
dispensing closures for bottled water, flavored water and sports drinks. The
Company offers a wide variety of plastic closures under each of its principal
product lines to satisfy specific market application and customer requirements.
Most of the Company's plastic closures offer its snap-on feature, a design
preferred by packagers because it reduces production costs and leakage. The
Company's plastic closures also incorporate tear strips, breakaway bands or
other visible tamper evidency, a feature that has become an industry standard
for food and non-carbonated beverage products. The Company's plastic closures
range in size from 28mm to 110mm, and conform with international packaging
standards. The Company offers over 34 individual closure products. The Company
also offers 33 standard colors, in addition to custom-blended colors, and
sophisticated printing, embossing and adhesive labeling capabilities to provide
product distinction for its customers.
 
    The following table describes the Company's principal plastic closure
product lines.

    CAPPING EQUIPMENT
 
    The Company also designs, manufactures and markets capping equipment for use
in high speed bottling, filling and packaging production lines. A substantial
majority of the Company's plastic closure customers use the Company's capping
equipment. The Company's ability to supply capping equipment and technical
assistance along with its plastic closures represents an important competitive
advantage, as customers are assured that the Company's plastic closures will be
applied properly to provide leakproof seals, and that any capping problems will
be resolved quickly.
 
    PORTAPLANTS
 
    In addition to plastic closures and capping equipment, the Company also
designs, manufactures and markets customized five gallon water capping and
filling systems. The Company's most comprehensive five gallon water bottling
system is its PortaPlant system. The PortaPlant is a compact bottle washing,
filling, capping and conveying system for glass and plastic water bottles that
can, depending on size, process 150 to 2,000 bottles per hour. The PortaPlant's
modular design makes it ideal for new and small water bottling companies as well
as established companies whose growth requires integrated expansion. Portola has
focused its sales efforts for PortaPlants internationally as less developed
countries look for improved distribution of safe and reliable drinking water.
 
    PLASTIC BOTTLES
 
    In Canada, the Company also produces plastic bottles.
 
PRODUCT DEVELOPMENT
 
    The Company continues to be committed to product development and
engineering. Its research and development group and engineering staff provide a
range of design and development services, focusing primarily on (i) new products
and product enhancements, (ii) tooling and molds necessary for manufacturing
plastic closures and (iii) capping equipment compatible with the Company's
closures and its customers' containers. Research and development expenditures
for fiscal 1997, 1996 and 1995 were $2.4 million, $2.2 million and $1.7 million
respectively.
 
    The Company has also made a substantial investment in developing new product
applications for existing markets as well as applications for new markets. To
facilitate the process of enhancing and developing new products and to ensure
ultimate market acceptance of such products, the Company encourages an on-going
exchange of ideas with customers, container manufacturers, machinery
manufacturers and sales and service personnel. This approach has enabled the
Company to identify new product opportunities.
 
    The Company's typical product development cycle has been less than one year.
However, successful introduction of a new closure product can take two to three
years, principally because customers who are comfortable with their existing
closure products are generally slow to switch to a new design, particularly in
light of the relatively small cost of the closure component to the overall
packaging unit.
 
RAW MATERIALS AND PRODUCTION
 
    The principal raw material for the Company's plastic closures is injection
molding grade LDPE resin, which generally accounts for at least 50% of the cost
of all raw materials purchased for the Company's plastic closures. The Company
believes that due to its volume purchases it is able to negotiate attractive
pricing with resin suppliers although prices for LDPE resin can fluctuate
substantially over relatively short periods of time. The Company has not
experienced any significant difficulties over the past ten years in obtaining
sufficient quantities of LDPE resin. In the past, the Company has been able to
pass substantially all resin price increases on to its customers on a timely
basis. However, significant increases in resin prices,
 
                                       6
<PAGE>
coupled with an inability to pass such increases on to customers promptly, would
have a material adverse effect on the Company's financial condition and results
of operations.
 
    In order to produce plastic closures, the resin, which is delivered as small
pebble-size pellets to large storage silos, is conveyed through a pipeline
system to an injection molding machine, where it is melted into a thick liquid
state. Coloring agents are added as appropriate and the mixture is injected at
high pressure into a specially designed, multi-cavity mold. The principal
equipment in the Company's plants includes injection molding machines, finishing
lines to print and label caps and line them with foam or foil to meet customer
requirements, and automated systems for handling and processing raw materials
and finished goods. By automating its manufacturing operations, the Company is
able to limit its direct labor costs while meeting the strict sanitary
requirements necessary for producing food and beverage packaging products.
 
    In the past, the Company designed and manufactured many of its own molds.
However, the increasing size and complexity of certain molds for new products
have caused the Company to out-source its mold construction needs. The Company
maintains design control over these molds as well as the molds it still builds.
The Company believes its mold expertise has led to reduced costs due to shorter
molding cycle times and enhanced reliability and longevity of its tooling.
 
BACKLOG
 
    Production and delivery cycles for closures is very short and the Company's
backlog for closures is generally cancelable on short notice. Contracts for
equipment purchases generally include cancellation penalties. There is no
assurance that some portion of the backlog may not be canceled or that the level
of backlog at any particular time is an appropriate indicator of the future
operating performance of the Company. Due to the short production and delivery
cycles for closures, the Company does not believe backlog information is a
material factor in understanding its business. Backlog for closures is generally
two to three weeks of orders, and is relatively constant from period to period.
 
SALES, MARKETING AND CUSTOMER SERVICE
 
    The Company markets its products through its internal sales department and
through domestic and international networks of independent sales
representatives. Calls on customers by these salespersons and representatives,
along with participation at trade shows, are the primary means of customer
contact. A number of the Company's customers are large corporate clients with
numerous production facilities, each of which may make its own separate
purchasing decisions. The Company's most significant customers are processors
and packagers of fluid milk, non-carbonated bottled water, chilled juice, other
flavored drinks and condiments for wholesale and institutional use. The
Company's customer base includes over 3,000 accounts. The Company's top ten
customers and buying groups accounted for approximately 40% of the Company's
sales during the fiscal year ended August 31, 1997, and none accounted for more
than 9% of sales during that period. Most of the Company's customers have been
doing business with the Company for more than ten years.
 
    Attention to customer service is a critical component of the Company's
marketing effort. The Company's customers operate high-speed, high-volume
production lines, with many handling perishable products. In order to assure
that the production lines operate efficiently and avoid costly line stoppages,
customers rely on the Company's ability to provide reliable, on-time delivery of
its closure products and to maintain the uniform quality of those products. The
Company also provides technical assistance to its customers in the form of an
in-house service team that can be dispatched on short notice to solve a bottling
line problem throughout the country. Several of the Company's field service
representatives have extensive blowmolding technical expertise that is
especially important in resolving bottle leakage problems for customers.

EXPORT SALES AND JOINT VENTURES
 
    Although the Company's sales are primarily domestic, the Company expects
significant growth in international sales, particularly in the market for water
cooler bottle closures and water bottle capping and filling equipment. The
United States bottled water industry, in general, uses more sophisticated
packaging materials and processes than bottled water companies use in the rest
of the world. The Company believes that bottled water companies and other
non-carbonated beverage companies in Europe, the Far East, Latin America and
elsewhere are beginning to adopt more advanced packaging materials and
techniques, and that, as they do, they will become potential customers for the
Company's plastic closure products and equipment. For the fiscal years ended
August 31, 1997, 1996 and 1995, export sales to unaffiliated customers were
$12,018,000, $17,568,000 and $18,658,000, respectively. The Company's export
sales have declined as the UK and Canadian subsidiaries have produced and sold
product locally. Sales are growing in these regions but through local
manufacture.
 
    In the last several years, the Company has utilized joint ventures with
bottle manufacturers, bottlers and distributors to gain footholds in
international markets. By offering plastic closures, capping equipment and
turnkey bottling systems, the Company can provide joint venture partners with a
complete solution to their bottling and capping requirements. In fiscal year
1996, the Company had three international joint ventures: (i) a 50% interest in
Canada Cap Snap Corporation, a Canadian corporation formed in 1990 and engaged
in manufacturing and distributing 38mm bottle closures in Canada, (ii) a 50%
interest in Cap Snap (U.K.) Ltd., a corporation formed in the United Kingdom in
1992 with a local bottle manufacturer to manufacture and sell 38mm caps, and
(iii) a 50% interest in Cap Snap Mexico, a joint venture formed in Mexico in
1993 with a local producer of plastic bottles and closures. In June 1995, the
Company consummated the Western Canadian Acquisition by acquiring the remaining
50% interest in Canada Cap Snap Corporation, together with a 100% interest in
two affiliated plastic bottle manufacturing companies. In September 1995, the
Company consummated the U.K. Acquisition by acquiring the remaining 50% interest
in Cap Snap (U.K.) Ltd. On November 14, 1997, the Company signed a joint venture
agreement, commiting to invest $1.65 million, with the Shanghai Aquarius
Drinking Water Company to manufacture and sell closures and bottles for the
Asian marketplace. Aquarius is a leading bottled water company in the Shanghai
Province of China.
 
COMPETITION
 
    The Company competes in marketing container closures to the food and
beverage industry on the basis of price, product design, product quality and
reliability, on-time delivery and customer service. Among the attributes that
the Company believes distinguish it from other sellers of closure systems and
provide a competitive advantage are the Company's proprietary products, the
Company's ability to provide its customers with innovative, low-cost closures
and complete capping systems, the Company's reputation for quality, reliability
and service and the Company's automated and strategically located production
facilities.
 
    While no single competitor offers products that compete with all of the
Company's product lines, the Company faces direct competition in each of its
product lines from a number of companies, many of which have financial and other
resources that are substantially greater than those of the Company. As the
Company broadens its product offerings, it can expect to meet increased
competition from additional competitors with entrenched positions in those
product lines. The Company also faces direct competition from bottling companies
and other food and beverage providers that elect to produce their own closures
rather than purchase them from outside sources. In addition, the packaging
industry has numerous well-capitalized competitors, and there is a risk that
these companies will expand their product offerings, either through internal
product development or acquisitions of any of the Company's direct competitors,
to compete in the niche markets that are currently served by the Company. These
competitors, as well as existing competitors, could introduce products or
establish prices for their products in a manner that could adversely affect the
Company's ability to compete. Because of the Company's product concentration, an
 
                                       8
<PAGE>
increase in competition or any technological innovations with respect to the
Company's specific product applications, such as the introduction of
lower-priced competitive products or products containing technological
improvements over the Company's products, could have a significant material
adverse effect on the Company's financial condition and results of operations.
 
EMPLOYEES
 
    As of October 31, 1997, the Company had 899 full-time employees, 25 of whom
were engaged in product development, 74 in marketing, sales and customer
support, 725 in manufacturing and 75 in finance and administration. The Company
uses seasonal and part time employees for training, vacation replacements and
other short term requirements. None of the Company's employees in the United
States is represented by any collective bargaining agreements (approximately 25
of the employees of one of the Company's Canadian subsidiaries are members of
the Teamsters Union), and the Company has never experienced a work stoppage. The
Company believes that its employee relations are good.
 
ITEM 2.  PROPERTIES
 
    The Company currently owns or leases nine modern production facilities,
located in the United States, which operate five to seven days a week, 24 hours
a day. One of the nine production facilities was closed in July, 1997 and has
been listed for sale. The Company's western Canadian subsidiary leases two
production facilities and the Company's eastern Canadian subsidiary leases one
production facility. In addition, the Company recently leased a manufacturing
facility located in Doncaster, South Yorkshire, England for use by its United
Kingdom subsidiary. The Company's facilities are highly efficient due to
automation and frequently scheduled maintenance throughout the plants. The
Company believes that these facilities are well-maintained and in good operating
condition and anticipates that, although substantial capital expenditures will
be required to meet the production requirements for new and developing product
lines, the facilities themselves will be sufficient to meet the Company's needs
for the next several years. There can be no assurance, however, that
unanticipated developments will not occur that would require the Company to
 
                                       9
<PAGE>
add production facilities sooner than expected. The following table indicates
the locations, functions, square footage and nature of ownership of the
Company's current facilities.

(1) The facilities shown as leased in the table above are subject to long-term
    leases or lease options that extend for at least five years, except as
    follows: the lease of the Clifton Park facility expires in 1998 and the
    leases for the Richmond and Edmonton facilities expire in 2000.
 
(2) The Company closed this facility in July of 1997. This property has been
    listed for sale.
 
ITEM 3.  LEGAL PROCEEDINGS.
 
    The plastic closure industry is characterized by frequent litigation
regarding patent and other intellectual property rights. The Company and certain
of its subsidiaries are engaged in patent infringement litigation with various
parties who are seeking to have the court declare certain patents owned by the
Company and such subsidiaries invalid. Some of these parties have also included
allegations of anti-trust violations in their complaints. The Company believes
that its patents and the patents of its subsidiaries are valid and is contesting
these allegations vigorously. There can be no assurance, however, that the
Company or its subsidiaries will be successful in their defense of these
matters. In addition, there can be no assurance that other infringement
litigation will not be brought in the future against the Company or its
subsidiaries, that any such litigation will not be expensive and protracted or
that, as a result of such litigation, the Company or its subsidiaries will not
be required to terminate a business practice or seek to obtain a license to the
intellectual property of others.
 
    The Company is also party to a number of other lawsuits and claims arising
out of the normal course of business. Although the ultimate outcome of these
matters is not presently determinable, management does not believe the final
disposition of these matters will have a material adverse effect on the
financial position, results of operations or cash flows of the Company.
 
ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.
 
    None.

ITEM 5.  MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS
 
    The Company's equity securities are privately held and no class of voting
securities is registered pursuant to Section 12 of the Securities Exchange Act
of 1934, as amended. There is no established trading market for any class of the
Company's common equity.
 
    The Company has two classes of common equity, Class A Common Stock and Class
B Common Stock, Series 1 and 2. Shares of Class A Common Stock are not entitled
to vote. The Company's Class B Common Stock, Series 1 and Class B Common Stock,
Series 2 have the same voting rights, each share being entitled to one vote.
 
    As of November 13, 1997, there were two holders of record of the 2,134,992
outstanding shares of Class A Common Stock. Additionally, there were two holders
of record of immediately exercisable warrants to purchase 2,492,741 shares of
Class A Common Stock. As of November 13, 1997, there were approximately 139
holders of record of the 8,456,534 outstanding shares of Class B Common Stock,
Series 1 and 5 holders of record of the 1,171,430 outstanding shares of Class B
Common Stock, Series 2.
 
    The Company has not paid dividends on its Common Stock in recent fiscal
years. It presently intends to continue this policy in order to retain any
earnings for the development of the Company's business. Furthermore, certain of
the Company's credit agreements, including the senior notes issued on October 2,
1995 and the senior revolving credit facility entered into on October 2, 1995,
restrict the Company's ability to pay dividends. In addition, the Canadian loan
agreements prohibit the western Canadian subsidiary from paying dividends to the
parent company.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
  OF OPERATIONS
 
OVERVIEW
 
    Portola Packaging, Inc. is a major designer, manufacturer and marketer of
tamper evident plastic closures and related equipment used for packaging
applications in dairy, bottled water, fruit juice, sports drinks and other
non-carbonated beverage products. The Company was acquired in 1986 through a
 
                                       13
<PAGE>
leveraged acquisition led by Jack L. Watts, the Company's current Chairman of
the Board and Chief Executive Officer. Since the acquisition, management has
focused its efforts on four principal areas: (i) continuing growth by converting
new customers to its plastic closures, (ii) developing new products and
improving existing products, (iii) achieving productivity improvements in its
manufacturing and material handling operations and (iv) seeking strategic
acquisitions including the acquisition of Northern Engineering & Plastics Corp.
("Nepco") and certain companies in Canada and the United Kingdom.
 
    On June 30, 1994, the Company acquired Nepco for a purchase price of $43.7
million. This acquisition has been accounted for as a purchase, and the results
of Nepco's operations have been consolidated with those of the Company
commencing July 1, 1994. On June 16, 1995, the Company consummated the Western
Canadian Acquisition in which the Company purchased for $13.6 million the 50%
interest it had not previously owned in Canada Cap Snap Corporation, a British
Columbia corporation engaged in manufacturing and distributing small closures in
western Canada, together with all the capital stock of two affiliated plastic
bottle manufacturers. These three companies were amalgamated in connection with
the closing of the acquisition and the combined entity now operates under the
name "Portola Packaging Canada Ltd." The Western Canadian Acquisition has been
accounted for as a purchase, and the results of the western Canadian operations
have been consolidated with those of the Company commencing June 16, 1995. On
September 1, 1995, the Company acquired, for approximately $1.5 million, the
remaining 50% interest it had not previously owned in Cap Snap (U.K.) Ltd., now
known as "Portola Packaging Limited." The U.K. Acquisition has been accounted
for as a purchase, and the results of the U.K. operations have been consolidated
with those of the Company commencing September 1, 1995. On September 1, 1996,
the Company consummated the Eastern Canadian Acquisition in which the Company
purchased for $2.1 million all of the capital stock of Rapid Plast J-P. Inc.
Rapid Plast was amalgamated with the wholly-owned subsidiary formed by the
Company to make the acquisition and was renamed "Portola Packaging Ltd." The
Eastern Canadian Acquisition has been accounted for as a purchase, and the
results of the eastern Canadian operations have been consolidated with those of
the Company commencing September 1, 1996.
 
    In April 1997, the Company's U.K. and eastern Canadian subsidiaries were
converted to "restricted subsidiary" status to allow greater flexibility in
funding the operations of these subsidiaries under the terms of the indenture
governing the senior notes issued by the Company in October 1995 and under the
terms of the Company's senior credit facility.
 
RESULTS OF OPERATIONS
 
    FISCAL YEAR ENDED AUGUST 31, 1997 COMPARED TO FISCAL YEAR ENDED AUGUST 31,
     1996
 
    Sales increased $11.0 million, or 6.9%, from $159.5 million for fiscal 1996
to $170.4 million for fiscal 1997. Of the increase, $6.2 million was
attributable to increased sales volume from the Canadian operations and $7
million was attributable to increased sales volume from the U.K. operations.
Sales from domestic closure operations remained relatively constant while
equipment sales decreased by $2.4 million. The majority of the increase in
sales, $7.6 million, was due to increases in closures sales volumes, consisting
principally of $4.2 million in increased sales of small closures, $1.9 million
in increases in sales of fitments and $1.5 million in increases in sales of
5-gallon and widemouth closures. These sales increases were primarily the result
of increased unit sales, and price increases were not a factor.
 
    Gross profit decreased $6.7 million, or 16.1%, to $35.1 million for fiscal
1997, as compared to $41.9 million for fiscal 1996. Gross profit as a percentage
of sales decreased from 26.3% for fiscal 1996 to 20.6% in fiscal 1997. The
margin decrease was due to the mix of sales, with a higher sales volume in units
coming from the Canadian and U.K. operations, all of which have experienced
relatively low margins. The Company anticipates sales from its Canadian and U.K.
operations to continue to comprise a larger percentage of its total sales than
has been the case in the past and in the near-term the margins from these
operations are anticipated to remain relatively low, although the Company
expects that over time the
 
                                       14
<PAGE>
margins from these operations will improve. U.K. margins will improve as the
U.K. subsidiary begins to manufacture products in its own production facility as
opposed to relying on subcontractors. Canadian margins will increase with
planned increased volume and better pricing with these subsidiaries' largest
customers. The gross margin in the equipment business was down as compared with
the same period last year. In addition, the margins in the domestic closure
business were down slightly from fiscal 1997 to fiscal 1996. Direct materials
remained constant at approximately 41% of sales and labor and overhead costs
have increased year on year. The Company has taken measures to improve
productivity and quality in its core business, and in December 1996 began
implementing a restructuring plan which consolidated its separate Closure,
Packaging and Manufacturing divisions. This restructuring plan included a
reduction in staff positions and the closure of its Portland, Oregon plant in
February 1997 and the closure of its Bettendorf, Iowa facility in July 1997. The
Company recorded a restructuring charge of $2.4 million and wrote off goodwill
of $1.7 million in connection with this restructuring plan in fiscal 1997.
 
    Selling, general and administrative expense decreased $2.3 million, or
10.4%, to $19.7 million for fiscal 1997, as compared to $22.0 million for fiscal
1996, and decreased as a percentage of sales from 13.8% for fiscal 1996 to 11.6%
for fiscal 1997. These decreases were primarily due to the decrease in bonus
payments from fiscal 1996 to fiscal 1997 as well as a reduction in staff
positions as a result of the restructuring that occurred during fiscal 1997.
 
    Research and development expenses increased slightly, to $2.4 million for
fiscal 1997, as compared to $2.2 million for fiscal 1996, and has remained
relatively constant as a percentage of sales at 1.4% in both years. The absolute
increase in research and development expenses was due primarily to increased
staffing to address expanded new product development opportunities and increased
expenditures for patent expenses.
 
    Amortization of intangibles (consisting of amortization of patents and
technology licenses, goodwill and covenants not to compete) decreased $1.9
million, or 36.2%, to $3.3 million for fiscal 1997, as compared to $5.2 million
for fiscal 1996. The decrease was primarily due to a decrease in patent
amortization due to the write-down of patent costs in fiscal 1996.
 
    In February 1997, the Company wrote off goodwill of $1.7 million in
connection with the closure of its Portland, Oregon plant.
 
    Total restructuring charges of $2.4 million were recorded in fiscal 1997. In
February 1997, the Company recorded a restructuring charge of $1.1 million
primarily for employee severance payments in connection with the closure of its
Portland, Oregon plant in February 1997 in accordance with its restructuring
plan. In addition, the Company recorded a restructuring charge of $1.3 million
in connection with the closure of its Bettendorf, Iowa facility in July 1997.
 
    Income from operations increased $336,000, or 6.5%, to $5.5 million for
fiscal 1997, as compared to $5.2 million for fiscal 1996, and stayed relatively
flat as a percentage of sales at 3.2% for both fiscal 1996 and fiscal 1997.
These changes were due to the factors summarized above.
 
    Interest income decreased $655,000 to $587,000 for fiscal 1997 from $1.2
million in fiscal 1996. This decline was primarily due to lower levels of
invested cash in fiscal 1997 as compared to fiscal 1996. Higher levels of cash
were available for investment during fiscal 1996 due to completion of the $110
million senior notes financing in early October 1995.
 
    Interest expense increased $295,000 to $13.4 million in fiscal 1997 as
compared to $13.1 million for the same period in fiscal 1996. These increases
were primarily due to a higher level of debt in fiscal 1997 due to the issuance
of $110 million of 10.75% senior notes due on October 2, 1995, and to a lesser
extent to borrowings under the Company's line of credit.
 
    Amortization of debt financing costs increased $67,000 to $559,000 in fiscal
1997 as compared to $492,000 for the same period in fiscal 1996. Debt financing
costs are primarily attributable to the
 
                                       15
<PAGE>
$110 million senior notes issued in October 1995 and, to a lesser extent, debt
financing incurred in western Canada.
 
    Income (loss) before extraordinary item improved to a $7.4 million loss in
fiscal 1997 compared to an $8.2 million loss in fiscal 1996. Net loss improved
to a $7.4 million loss in fiscal 1997 as compared to a $9.4 million loss in
fiscal 1996.
 
    An extraordinary item of $1.3 million, net of taxes, was recorded during
fiscal 1996, as loan fees and other costs expensed in connection with an early
extinguishment of debt resulting from the $110 million senior notes issue in
October 1995.
 
    FISCAL YEAR ENDED AUGUST 31, 1996 COMPARED TO FISCAL YEAR ENDED AUGUST 31,
     1995
 
    Sales increased $34.8 million, or 27.9%, from $124.7 million for fiscal 1995
to $159.5 million for fiscal 1996. Of the increase, $8.1 million was
attributable to sales from western Canadian operations acquired by the Company
on June 16, 1995 and $5.7 million was attributable to sales from the U.K.
operations acquired by the Company on September 1, 1995. Equipment sales
increased $3.2 million, primarily due to an increase in sales of fitment
applicator equipment, somewhat offset by a decrease in sales of water and dairy
applicator equipment. The majority of the increase in sales, $18.5 million, was
due to increases in closures sales volumes, consisting principally of $10.3
million in increased sales of small closures, $5.7 million in increases in sales
of fitments and $2.5 million in increases in sales of 5-gallon and widemouth
closures.
 
    Gross profit increased $9.2 million, or 28.1%, to $41.9 million for fiscal
1996, as compared to $32.7 million for fiscal 1995. Gross profit as a percentage
of sales remained constant at 26.2% for fiscal 1996 and 1995. The absolute
increase in gross profit was primarily due to increased sales in closure
products and, to a lesser extent, the June 1995 acquisition of the western
Canadian operations, offset by a loss from the U.K. operations acquired in
September 1995.
 
    Selling, general and administrative expense increased $5.4 million, or
32.4%, to $22.0 million for fiscal 1996, as compared to $16.6 million for fiscal
1995, and increased as a percentage of sales from 13.4% for fiscal 1995 to 13.8%
for fiscal 1996. Of the absolute increase, approximately $1.6 million
represented increased commissions and approximately $785,000 was due to
increased advertising, public relations and marketing consulting expenses. The
higher level of sales in fiscal 1996 as compared to fiscal 1995 resulted in an
increase in commission expense. The remaining increases were primarily due to
the increased size of the corporation and resulting infrastructure increases.
 
    Research and development expenses increased $474,000, or 28.2%, to $2.2
million for fiscal 1996, as compared to $1.7 million for fiscal 1995, and
increased as a percentage of sales from 1.3% in fiscal 1995 to 1.4% in fiscal
1996. The absolute increase in research and development expenses was due
primarily to increased expenditures for new product prototypes and patent
expenses.
 
    Amortization of intangibles (consisting of amortization of patents and
technology licenses, goodwill and covenants not to compete) increased $1.5
million, or 39.8%, to $5.2 million for fiscal 1996, as compared to $3.7 million
for fiscal 1995. Of the increase, approximately $600,000 was due to an increase
in amortization of patents and acquired technology, primarily resulting from the
U.K. acquisition and approximately $315,000 resulted from the increase in
amortization of goodwill, primarily resulting from the Western Canadian and U.K.
Acquisitions and approximately $550,000 of the increase related to amortization
of the covenant not to compete relating to the Western Canadian Acquisition.
 
    The write-off of intangibles of $7.3 million in fiscal 1996 related to the
adoption of Financial Accounting Standards Board Statement No. 121 "Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed
Of" (SFAS 121) during fiscal 1996, which requires the Company to review for
impairment long-lived assets, certain identifiable intangibles, and goodwill
related to those assets whenever events or changes in circumstances indicate
that the carrying amount of an asset may not
 
                                       16
<PAGE>
be recoverable. This statement requires impairment losses to be recognized for
assets that do not have realizable carrying values, and requires valuation of
impairments at the lowest level of identifiable cash flows. Previously, the
Company evaluated long-lived assets on a divisional or group basis using
undiscounted cash flows. Due to changes in market conditions in certain markets
and manufacturing facilities, the Company evaluated portions of its goodwill
recorded in connection with its acquisitions of Nepco and Portola Packaging
Canada Ltd. The Company recorded impairment losses of $421,000 and $2,332,000
related to goodwill recorded in the acquisition of Nepco and Portola Packaging
Canada Ltd., respectively. The Company also undertook a detailed study of its
patents and began to evaluate cash flows on an individual product family basis
for impairment. Previously, patents were evaluated on a group basis for
impairment. This change in methodology was implemented to be consistent with
SFAS 121's requirement to evaluate cash flows from intangibles at the lowest
identifiable level and resulted in a write-down of $4,539,000.
 
    Income from operations decreased $5.4 million, or 51.2%, to $5.2 million for
fiscal 1996, as compared to $10.6 million for fiscal 1995, and decreased as a
percentage of sales from 8.5% for fiscal 1995 to 3.2% for fiscal 1996. These
changes were due to the factors summarized above and primarily reflect the
write-off of intangible assets of $7.3 million.
 
    Net interest expense increased $3.3 million to $11.8 million for fiscal
1996, as compared to $8.5 million for fiscal 1995, primarily as a result of
increased borrowings to fund acquisitions, capital expenditures and higher
working capital requirements associated with increased sales levels.
 
    Amortization of debt financing costs increased $45,000 to $492,000 for
fiscal 1996, as compared to $447,000 for fiscal 1995.
 
    Income taxes decreased $429,000 to $865,000 for fiscal 1996, as compared to
$1.3 million for fiscal 1995.
 
    Income (loss) before extraordinary item decreased to a loss of $8.2 million
in fiscal 1996 compared to income of $140,000 in fiscal 1995. Net income (loss)
decreased to a loss of $9.4 million in fiscal 1996 as compared to income of
$140,000 in fiscal 1995. In October 1995, the Company refinanced its debt to
provide additional capacity for growth, resulting in an extraordinary charge of
$1.3 million, net of taxes, relating to loan fees and other costs relating to
the early extinguishment of debt.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    The Company has relied primarily upon cash from operations and borrowings
from financial institutions and sales of common stock, to finance its
operations, repay long-term indebtedness and fund capital expenditures and
acquisitions. On October 2, 1995, the Company completed its offering of a $110
million senior notes offering (the "Notes") that mature on October 1, 2005 and
bear interest at the rate of 10.75% per annum. The net proceeeds of the Notes
offering were approximately $106 million, of which $83 million was used to
retire the Company's debt then outstanding under its senior term loans,
revolving facility and senior subordinated notes. Subsequent to the closing of
the Notes offering, $7.2 million was used to purchase the Company's San Jose
facilities, $11 million was used to purchase machinery and equipment, $3 million
was used to collateralize a loan made by a bank to the Company's 50% joint
venture in Mexico, and $2 million was used for working capital needs. At August
31, 1997, the Company had cash and cash equivalents of $3.2 million, a decrease
of $4.6 million from August 31, 1996.
 
    Cash provided by operations totaled $14.7 million in fiscal 1997, a $4.1
million decrease from $18.8 million in fiscal 1996. Working capital decreased
$14.1 million in fiscal 1997 to $7.3 million, as compared to $21.4 million in
fiscal 1996, primarily as a result of increases in the current portion of long
term debt and accrued liabilities, and decreases in inventories and cash.
 
    Capital expenditures were $23.1 million in fiscal 1997 compared to $27.2
million in fiscal 1996, which in fiscal 1996 included $7.2 million related to
the purchase of the Company's San Jose facilities. The Company anticipates that
capital expenditure levels for fiscal 1998 will be approximately $12 million to
$16 million. In addition, the Company is subject to certain future obligations
regarding noncompete and bonus arrangements as a result of certain acquisitions.
At August 31, 1997 the present value of the covenants not to compete under the
Nepco and Western Canadian Acquisitions were $1.6 million and $0.7 million,
respectively.
 
                                       17
<PAGE>
    In March 1997, the Company was advised that the prospectus used by an
affiliate of the Company in connection with secondary market sales of
approximately $14 million of the Company's Notes did not contain current
financial information about the Company. The Notes sold during this period by
the Company's affiliate may be subject to rescission, which may result in
liability for the Company for any loss incurred in connection with a rescission.
No liability has been accrued in the financial statements as of August 31, 1997
in connection with this matter since the Company has not made a determination
that it is probable that a loss on rescission will be incurred by the Company.
The Company believes that its cash resources, including its borrowings under its
line of credit, are adequate to cover any such loss without materially affecting
the normal conduct of its business.
 
    In September 1996 the Company completed the acquisition of Rapid Plast J-P.
Inc., a Canadian federal company headquartered in Montreal, Quebec, for a total
purchase price of approximately $2.1 million. Rapid Plast was amalgamated with
the wholly-owned subsidiary formed by the Company to make the acquisition and
was renamed Portola Packaging Ltd. ("Portola Canada Ltd."). Portola Canada Ltd.
is engaged in manufacturing and distributing plastic bottles, primarily in
eastern Canada. This transaction has been accounted for as a purchase and
therefore the results of operations subsequent to the acquisition are
consolidated with the Company.
 
    Until fiscal 1996, the Company had been the defendant in litigation with
Scholle Corporation ("Scholle") related to alleged patent infringement on
five-gallon non-spill caps. On January 2, 1996, the court denied further motions
and entered the jury's verdict making the Company liable for damages of $0.01
per closure unit sold. In June 1996, the Company reached a settlement agreement
with Scholle, whereby Scholle granted to the Company a non-exclusive license to
use certain of its patents, and the Company agreed to pay a royalty to Scholle
of $0.01 per five gallon non-spill closure unit sold. The Company remained
liable for damages of $0.01 per closure unit sold prior to the date of the
settlement agreement, plus interest at a rate of 10% on all past due amounts.
The Company made a payment of $1.7 million to Scholle on July 1, 1996 in
settlement of all amounts due, including interest, through May 31, 1996. Such
amounts had been accrued in the Company's financial statements.
 
    At August 31, 1997, the Company had total indebtedness of $121.9 million. In
October 1995 the Company completed its offering of the Notes and repaid all
outstanding debt under its senior term loans, revolving facility and senior
subordinated notes. Concurrently with the offering, the Company entered into a
new five-year senior secured revolving credit facility of up to $35.0 million,
subject to a borrowing base of eligible receivables and inventory. This credit
facility contains covenants and provisions that restrict, among other things,
the Company's ability to: (i) incur additional indebtedness, (ii) incur liens on
its property, (iii) make investments, (iv) enter into guarantees and other
contingent obligations, (v) merge or consolidate with or acquire another person
or engage in other fundamental changes, (vi) engage in certain sales of assets,
(vii) engage in certain transactions with affiliates and (viii) make restricted
junior payments.
 
    At August 31, 1997 the Company had $3.2 million in cash and cash
equivalents, as well as unused borrowing capacity of approximately $31 million
under its revolving credit facility. Management believes that these resources,
together with anticipated cash flow from operations, will be adequate to fund
the Company's operations, debt service requirements and capital expenditures
through fiscal 1998.
 
INFLATION
 
    Most of the Company's closures are priced based in part on the cost of the
plastic resins from which they are produced. Historically, the Company has been
able to pass on increases in resin prices directly to its customers on a timely
basis. In recent years, the Company has benefited from relatively stable or
declining prices for raw materials other than plastic resins.
 
SEASONALITY
 
    The Company's sales and earnings reflect a seasonal pattern as a result of
greater sales volumes during the summer months. For example, in fiscal 1997, 47%
of sales occurred in the first half of the year
 
                                       18
<PAGE>
(September through February) while 53% of sales were generated in the second
half (March through August). The effect of seasonality on income from operations
is usually somewhat more pronounced in the second half of the fiscal year.
 
INCOME TAXES
 
    Income tax expense does not bear a normal relationship to income before
income taxes primarily due to nondeductible goodwill arising from the Nepco and
other acquisitions.
 
RECENT ACCOUNTING PRONOUNCEMENTS
 
    In February 1997, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards (SFAS) 128, "Earnings per Share." SFAS 128 is
effective for quarterly periods ending after December 15, 1997. SFAS 128
requires presentation and calculation of a simplified earnings per share and
that prior periods be restated to conform to that revised presentation and
calculation.
 
    In February 1997, the Financial Accounting Standards Board issued SFAS 129,
"Disclosure of Information about Capital Structure." SFAS 129 requires
disclosure about an entity's capital structure and contains no change in
disclosure requirements for entities that were subject to the previously
existing requirements SFAS 129 is effective for the Company's fiscal year 1999.
 
    In June 1997, the Financial Accounting Standards Board issued SFAS 130,
"Reporting Comprehensive Income." SFAS 130 establishes standards for reporting
and display of comprehensive income and its components in a full set of
general-purpose financial statements. It is effective for the Company's fiscal
year 1999.
 
    In June 1997 the Financial Accounting Standards board issued SFAS 131,
"Disclosure About Segments of an Enterprise and Related Information." SFAS 131
changes current practice under SFAS 14 by establishing a new framework on which
to base segment reporting (referred to as the "management" approach) and also
requires interim reporting of segment information. It is effective for the
Company's fiscal year 1999.
 
    The Company is currently studying the implications of these statements and
has not yet determined the impact of their adoption.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
TO THE BOARD OF DIRECTORS AND SHAREHOLDERS
PORTOLA PACKAGING, INC. AND SUBSIDIARIES:
 
    We have audited the accompanying consolidated balance sheets of Portola
Packaging, Inc. and Subsidiaries as of August 31, 1997 and 1996, and the related
consolidated statements of operations, shareholders' equity (deficit) and cash
flows for each of the three years in the period ended August 31, 1997. 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 Portola
Packaging, Inc. and Subsidiaries as of August 31, 1997 and 1996, and the
consolidated results of their operations and their cash flows for each of the
three years in the period ended August 31, 1997 in conformity with generally
accepted accounting principles.
 
    As discussed in Note 3 to the consolidated financial statements, in fiscal
1996 the Company adopted a newly established standard for the impairment of
long-lived assets.

                     (IN THOUSANDS, EXCEPT PER SHARE DATA)
 
1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
NATURE OF OPERATIONS:
 
    Portola Packaging, Inc. and Subsidiaries (the "Company") designs,
manufactures and markets tamper-evident plastic closures and related equipment
used for packaging applications in dairy, fruit juice, bottled water,
institutional foods and other non-carbonated beverage products. The Company has
production facilities in the United States, Canada, United Kingdom and Mexico
(through a joint venture).
 
PRINCIPLES OF CONSOLIDATION:
 
    The consolidated financial statements include the financial statements of
the Company and its wholly owned subsidiaries. All material intercompany
accounts and transactions have been eliminated.
 
REVENUE RECOGNITION:
 
    The Company recognizes revenue upon product shipment.
 
CASH EQUIVALENTS:
 
    The Company considers all highly liquid investments with original maturities
of three months or less to be cash equivalents.
 
INVENTORIES:
 
    Inventories are stated at the lower of cost (first-in, first-out method) or
market.
 
INVESTMENTS:
 
    Investments as of August 31, 1997 and 1996 consisted of equity securities in
one company. Investments are generally considered to be available-for-sale and
therefore are carried at fair market value. Unrealized holding gains and losses
on such securities, when material, are reported net of related taxes as a
separate component of common stock and other shareholders' deficit. Realized
gains and losses on sales of all such investments are reported in earnings and
computed using the specific cost identification method.
 
PROPERTY, PLANT AND EQUIPMENT:
 
    Property, plant and equipment are stated at cost and are depreciated on the
straight-line basis over their estimated useful lives, which range from three to
thirty-five years. Leasehold improvements are amortized on a straight-line basis
over their useful lives or the lease term, whichever is shorter (generally five
to ten years). When assets are disposed of, the cost and related accumulated
depreciation are removed from the accounts and the resulting gains or losses are
included in the results of operations.
 
JOINT VENTURE:
 
    The Company maintains a joint venture and license arrangement in Mexico.
This investment, which is included in other assets, is accounted for by the
equity method. The Company's share of income (loss) from the joint venture is
reflected in operations and is not material.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
                     (IN THOUSANDS, EXCEPT PER SHARE DATA)
 
INTANGIBLE ASSETS:
 
    Patents and covenants not-to-compete are valued at cost and are amortized on
a straight-line basis over the lesser of their remaining useful or contractual
lives (generally five to thirteen years). Goodwill recorded in connection with
acquisitions of Nepco, Portola Packaging Canada Ltd. and Portola Packaging
Limited (Note 2) is amortized on a straight-line basis over 15, 25 and 5 years,
respectively.
 
DEBT FINANCING COSTS:
 
    Debt financing costs are amortized using the interest method over the term
of the related loans.
 
RESEARCH AND DEVELOPMENT EXPENDITURES:
 
    Research and development expenditures are charged to operations as incurred.
 
INCOME TAXES:
 
    The Company accounts for income taxes under the liability method which
requires deferred taxes be computed on an asset and liability method and
adjusted when new tax laws or rates are enacted. Deferred tax assets and
liabilities are determined based on the differences between the financial
reporting and tax bases of assets and liabilities and are measured using enacted
tax rates and laws that will be in effect when the differences are expected to
reverse.
 
CONCENTRATIONS OF CREDIT RISK AND OTHER RISKS AND UNCERTAINTIES:
 
    Financial instruments which potentially subject the Company to
concentrations of credit risk consist principally of cash and cash equivalents,
short term investments and trade receivables. The Company's cash and cash
equivalents and investments are concentrated primarily in several United States
banks. At times, such deposits may be in excess of insured limits. Management
believes that the financial institutions which hold the Company's investments
are financially sound and, accordingly, minimal credit risk exists with respect
to these financial instruments.
 
    The Company's products are principally sold to entities in the food and
beverage industries in the United States and Canada. Ongoing credit evaluations
of customer financial condition are performed and collateral is generally not
required. The Company maintains reserves for potential credit losses which, on a
historical basis, have not been significant.
 
    The majority of the Company's products are molded from various plastic
resins which comprise a significant portion of the Company's cost of sales.
These resins are subject to substantial price fluctuations resulting from
shortages in supply, changes in prices in petrochemical products and other
factors. Significant increases in resin prices coupled with an inability to
promptly pass such increases on to customers would have a material adverse
impact on the Company.
 
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
reporting period. Actual results could differ from those estimates.

                     (IN THOUSANDS, EXCEPT PER SHARE DATA)
 
FOREIGN CURRENCY TRANSLATION:
 
    The Company's foreign subsidiaries use the local currency as their
functional currency. Assets and liabilities are translated at year-end exchange
rates. Items of income and expense are translated at average exchange rates for
the relevant year. Translation gains and losses are not included in determining
net income (loss) but are accumulated as a separate component of shareholders'
equity (deficit). Net gains and losses arising from foreign currency
transactions were not material for any periods presented.
 
COMPUTATION OF EARNINGS (LOSS) PER COMMON SHARES:
 
    Earnings (loss) per common share and common equivalent share is computed by
dividing income (loss) by the weighted average number of shares of common stock
and common stock equivalents outstanding during the period. Except as discussed
below, the number of common shares is increased by the number of shares issuable
on the exercise of options and warrants when the market price of the common
stock exceeds the exercise price of the options and warrants. This increase in
the number of common shares is reduced by the number of common shares which are
assumed to have been purchased with the proceeds from the exercise of the
options and warrants; these purchases are assumed to have been made at the
average price of the common stock during that part of the period when the market
price of the common stock exceeds the exercise price of the options and
warrants.
 
    Since the Company's warrants include a put provision, Emerging Issues Task
Force (EITF) Consensus 88-9 requires computation of earnings (loss) per share
using the lower of the amount computed assuming conversion, as described above,
or the amount computed assuming exercise of the put option feature of the
warrants. Earnings (loss) per share computed using the put option feature is the
more dilutive of the calculations in fiscal 1997, 1996 and 1995. The accretion
of the warrants of $1,115, $895 and $610 for fiscal 1997, 1996 and 1995
respectively, is deducted from earnings to derive earnings (loss) per share.
 
CARRYING VALUE OF LONG-LIVED ASSETS:
 
    Long-lived assets, including goodwill related to those assets and goodwill
unrelated to specific assets are evaluated for impairment whenever events or
changes in circumstances indicate that the carrying amount of an asset may not
be recoverable.
 
RECENT ACCOUNTING PRONOUNCEMENTS:
 
    In February 1997, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards (SFAS) 128, "Earnings per Share." SFAS 128 is
effective for quarterly periods ending after December 15, 1997. SFAS 128
requires presentation and calculation of a simplified earnings per share and
that prior periods be restated to conform to that revised presentation and
calculation.
 
    In February 1997, the Financial Accounting Standards Board issued SFAS 129,
"Disclosure of Information about Capital Structure." SFAS 129 requires
disclosure about an entity's capital structure and contains no change in
disclosure requirements for entities that were subject to the previously
existing requirements. SFAS 129 is effective for the Company's fiscal year 1999.
 
    In June 1997, the Financial Accounting Standards Board issued SFAS 130,
"Reporting Comprehensive Income." SFAS 130 establishes standards for reporting
and display of comprehensive income and its components in a full set of
general-purpose financial statements. It is effective for the Company's fiscal
year 1999.

                     (IN THOUSANDS, EXCEPT PER SHARE DATA)
 
    In June 1997, the Financial Accounting Standards board issued SFAS 131,
"Disclosure About Segments of an Enterprise and Related Information." SFAS 131
changes current practice under SFAS 14 by establishing a new framework on which
to base segment reporting (referred to as the "management" approach) and also
requires interim reporting of segment information. It is effective for the
Company's fiscal year 1999.
 
    The Company is currently studying the implications of these statements and
has not yet determined the impact of their adoption.
 
FAIR VALUE OF FINANCIAL INSTRUMENTS:
 
    Carrying amounts of certain of the Company's financial instruments including
cash and cash equivalents, accounts payable and other liabilities approximate
fair value due to their short maturities. Based on borrowing rates currently
available to the Company for loans with similar terms, the carrying value of the
long term debt approximates fair value.
 
RECLASSIFICATIONS:
 
    Certain prior year balances have been reclassified to conform with the
current year financial statement presentation. These reclassifications had no
effect on net income (loss) or total assets.
 
2.  ACQUISITIONS:
 
    On September 1, 1996, the Company completed the acquisition of Rapid Plast
J-P Inc., a Canadian federal corporation, for a purchase price of $2,138. Rapid
Plast was amalgamated with the company formed to acquire the capital stock of
Rapid Plast, and now operates under the name Portola Packaging Ltd. Portola
Packaging Ltd. is engaged in manufacturing and distributing plastic bottles,
primarily in eastern Canada. This transaction has been accounted for as a
purchase and therefore the results of operations subsequent to the acquisition
are consolidated with the Company.
 
    Portola Packaging Ltd. is being operated as a "restricted subsidiary"
pursuant to the terms of the Indenture pertaining to the Senior Notes issued in
October 1995.
 
    Consideration for the acquisition was allocated as follows:

    On September 1, 1995, the Company completed the acquisition of the 50%
interest it had not previously owed in Cap Snap (UK) Ltd., now known as Portola
Packaging Limited ("Portola Packaging (UK)") for a purchase price of
approximately $1,500. Portola Packaging (UK) is a United Kingdom corporation
engaged in manufacturing and distributing small closures in the United Kingdom.
The transaction has been accounted for as a purchase and results of operations
subsequent to the acquisition date have been consolidated with the Company.
 
    Portola Packaging (UK) is being operated as a "restricted subsidiary"
pursuant to the terms of the Indenture pertaining to the Senior Notes issued in
October 1995.

    Effective June 16, 1995, the Company completed the acquisition of Alberta
Plastic Industries, Ltd., B.C. Plastic Industries, Ltd., the remaining 50%
interest of the Company's joint venture, Canada Cap Snap Corporation, and
certain production equipment of Allwest Industries Incorporation. The acquired
companies and assets operate in Canada as Portola Packaging Canada Ltd.
 
    The Canadian acquisition has been accounted for as a purchase and the
results of operations of Portola Packaging Canada Ltd. have been consolidated
with those of the Company commencing June 16, 1995. The total purchase price,
including cash consideration and a noncompete agreement, amounted to $13,572.
Cash consideration paid by the Company was $11,738. In addition, the Company
entered into a noncompete agreement under which an intangible asset totaling
$2,560 was recorded at the present value of the payments (using a discount rate
of 8.75%). A liability was recorded of $1,834, which represents the net present
value of the payments less the initial payment made upon the closing of the
Canadian acquisition.
 
    Consideration for the acquisition was allocated as follows:

</TABLE>
 
3.   WRITE-OFF OF INTANGIBLES:
 
    In the fourth quarter of fiscal 1996, the Company elected early adoption of
the provisions of Statement of Financial Accounting Standards (SFAS) No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
be Disposed of" issued by the Financial Accounting Standards Board in March
1995. SFAS 121 requires the Company to review for impairment long-lived assets,
certain identifiable intangibles, and goodwill related to those assets whenever
events or changes in circumstances indicate that the carrying amount of an asset
may not be recoverable.
 
    This statement requires impairment losses to be recognized for assets that
do not have realizable carrying values, and requires valuation of impairments at
the lowest level of identifiable cash flows. Previously, the Company evaluated
long-lived assets on a divisional or group basis using undiscounted cash flows.
 
    Due to changes in market conditions in certain markets and manufacturing
facilities in 1996, the Company evaluated portions of its goodwill recorded in
connection with its previous acquisitions and recorded impairment losses of $421
and $2,332, related to goodwill recorded in the acquisition of Nepco and Portola
Packaging Canada, Ltd., respectively.
 
    As a result of the adoption of SFAS 121, the Company undertook a detailed
study of its patents and began to evaluate cash flows on an individual product
family basis for impairment. Previously, patents were evaluated on a group basis
for impairment. This change in methodology was implemented to be consistent with
SFAS 121's requirement to evaluate cash flows from intangibles at the lowest
identifiable level and
 
                                       31
<PAGE>
                       PORTOLA PACKAGING AND SUBSIDIARIES
 
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
                     (IN THOUSANDS, EXCEPT PER SHARE DATA)
 
resulted in a writedown of $4,539 in fiscal 1996. The fair value of the patents
was estimated using discounted cash flows.
 
    The effect of adopting SFAS 121 on the financial statements was an increase
in fiscal 1996 expenses of $7,292. Consistent with the provisions of SFAS 121,
the additional expense related to adoption is included in fiscal 1996 results of
operations. This writedown had no effect on cash flows from operations or cash
available for debt service.
 
    In 1997, the Company also recorded a write-off of $1,720 of goodwill related
to its Portland, Oregon facility, which was closed in February 1997.
 
    SFAS 121 requires on going evaluations of impairments whenever events or
changes in circumstances indicate that the carrying amount of an asset may not
be recoverable. It is at least reasonably possible that future impairments could
occur, and those impairments could create a material effect on the financial
position and results of operations of the Company.
 
4.  RESTRUCTURING:
 
    The Company has taken measures to improve productivity and quality in its
core business, and in December 1996 began implementing a restructuring plan
which consolidates its separate Closure, Packaging, and Manufacturing divisions.
This restructuring plan includes a reduction in staff positions and the closure
of its Portland, Oregon plant in February 1997 and its Bettendorf, Iowa plant in
July 1997. The Company recorded a restructuring charge of approximately $2,394,
which consists primarily of employee severance and loss on property, plant and
equipment, in fiscal 1997 in connection with this restructuring plan.

    Base rent expense for the years ended August 31, 1997, 1996 and 1995 totaled
$1,860, $1,793 and $1,381, respectively, of which $0, $291 and $720 was paid to
Three Sisters Ranch Enterprises (Note 15) for the years ended August 31, 1997,
1996 and 1995, respectively.
 
    The Company is engaged in patent litigation with various other parties who
are seeking to have the court declare certain patents owned by the Company
invalid. The Company believes its patents are valid, and intends to vigorously
contest these actions. In some of these cases the Company has a claim against it
for alleged violations of the antitrust laws.
 
    The Company is also a party to a number of other lawsuits and claims arising
out of the normal course of business. The total claimed damages, in the cases in
which damages are specified, total approximately $1,500. The Company believes it
has meritorious defenses, intends to contest these claims vigorously, and may
have insurance to cover potential losses. Management does not believe the final
disposition of these matters will have a material adverse affect on the
financial position, results of operations or cash flows of the Company.
 
    In March 1997, the Company was advised that the prospectus used by an
affiliate of the Company in connection with secondary market sales of
approximately $14 million of the Company's Senior Notes did not contain current
financial information about the Company. The Senior Notes sold during this
period by the Company's affiliate may be subject to rescission, which may result
in liability for the Company for any loss incurred in connection with a
rescission. No liability has been accrued in the financial statements as of
August 31, 1997 in connection with this matter since the Company has not made a
determination that it is probable that a loss on rescission will be incurred by
the Company. The Company believes that its cash resources, including its
borrowings under its line of credit, are adequate to cover any such loss without
materially affecting the normal conduct of its business.
 
10.  REDEEMABLE WARRANTS:
 
    The Company has outstanding two warrants to purchase an aggregate of 2,493
shares of its Class A common stock which are held by certain of the Company's
shareholders and senior lenders. A warrant to purchase 2,053 shares of common
stock is exercisable, in whole or in part, through June 30, 2004 at sixty and
two-third cents per share, subject to certain antidilution provisions. After
June 30, 1999, if the Company has not completed an initial public offering of
its common stock, the warrant holder may require the Company to purchase the
warrant at a price equal to the higher of the current fair value per share of
the Company's common stock or an amount computed under an earnings formula in
the warrant agreement. The purchase obligation may be suspended under certain
circumstances including restrictions on such payments as specified in the senior
credit agreements. After December 31, 2001, the Company has

the right to repurchase the warrant at a price equal to the higher of the fair
value per share of the Company's common stock or an amount computed under an
earnings formula in the warrant agreement. The earnings formula is based on
income before interest, taxes and debt outstanding to calculate an estimated
value per share. For fiscal years ended August 31, 1997, 1996 and 1995 the
accretion was determined using the fair market value of the common stock.
 
    A second warrant to purchase 440 shares of Class A common stock may be
exercised at any time at $2.50 per share, until its expiration on June 30, 2004.
After August 1, 2001, if the Company has not completed an initial public
offering of its common stock, the holder may require the Company to purchase its
warrant at a price equal to the higher of the current fair value price per share
of the Company's common stock or the net book value price per share of the
Company's common stock or the net book value per share as computed under a
valuation formula set for in the warrant. The purchase obligation may be
suspended under certain circumstances including restriction on such payments as
specified in the Company's senior credit agreements. On or after August 1, 2003,
the Company has the right to repurchase the warrant at a price equal to the
higher of the current fair value per share of the Company's common stock or the
net book value per share. The earnings formula is based on earnings before
interest and taxes and debt outstanding to calculate an estimated value per
share. For fiscal years ended August 31, 1997, 1996 and 1995, the accretion was
determined using the fair value of the common stock.
 
    Generally accepted accounting principles require that an adjustment of the
warrant from the value assigned at the date of issuance to the highest
redemption price of the warrant be accreted over the period of the warrant. At
August 31, 1997, the estimated redemption value of the warrants exceeds their
carrying value. The difference is being charged to accumulated deficit over the
period from the date of issuance to the earliest put date of the warrants.
Charges to accumulated deficit related to the warrants amounted to $1,115, $895
and $610 during the years ended August 31, 1997, 1996 and 1995, respectively.
 
11.  SHAREHOLDERS' DEFICIT:
 
CLASS A AND B COMMON STOCK:
 
    The Company has authorized 5,203 shares of Class A common stock, of which
2,493 shares are reserved for the warrants described in Note 10. Class A common
shareholders are not entitled to elect members of the Board of Directors. In the
event of an aggregate public offering exceeding $10,000, the Class A and Class
B, Series 2 common stock is automatically converted into Class B, Series 1
common stock, based on the appropriate conversion formula. The Class B common
shareholders have the right to elect members of the Board of Directors, with the
holders of Series 1 having one vote per share, and the holders of Series 2
having a number of votes equal to the number of shares into which the Series 2
shares are convertible into Series 1 shares. In the event of liquidation or
dissolution in which the value of the Company is less than $1.75 per share of
common stock, the holders of Class B, Series 2 will receive 60% of the proceeds
until they have received $1.75 per share. All other amounts available for
distribution shall be distributed to the Class B, Series 1 and Series 2 holders
pro rata based on the number of shares outstanding. If the value of the Company
is greater than or equal to $1.75 per share, the holders of all classes of
common stock are entitled to a pro rata distribution based on the number of
shares outstanding.
 
    The Company is required to reserve shares of Class B, Series 1 common stock
for the conversion of Class A common stock and Class B, Series 2 common stock
into Class B, Series 1 common stock.

DIRECTORS' AGREEMENTS:
 
    The Company entered into Directors' Agreements dated September 1989 and
amended in January 1990 and August 1991, with certain directors who are also
shareholders of the Company. The agreements provided that the Company is to pay
up to $22 per year to each individual for serving as a director, and granted
each director the right to purchase up to 22 shares per year of Class B, Series
1 common stock at $1.00 per share through fiscal 1992. In October 1990, the
Company entered into a Director's Agreement with another director, who is also a
shareholder of the Company. The agreement provided that the Company pay up to
$22 per year for services as a director. In January 1996, the Company began
paying an additional $4 per year to directors who serve as members and
alternates of committees. The Board of Directors currently has two committees,
the audit committee and the compensation committee. In May 1996, the Company
entered into a Director's Agreement with another director, who is also a
shareholder of the Company. During the years ended August 31, 1997, 1996 and
1995, the Company paid $230, $96 and $64, respectively, in director fees and
related expenses.
 
STOCK OPTION PLAN:
 
    The Company has reserved 2,866 and 2,000 shares of Class B, Series 1 common
stock for issuance under the Company's 1988 and 1994 stock option plans,
respectively. Under both plans, stock options are granted by the Board of
Directors at prices not less than 85% of fair market value of the Company's
stock at the date of grant for non-qualified options and not less than 100% of
the fair market value of the Company's stock at the date of grant for incentive
options. The fair value of each option grant is estimated at the date of grant
using the Black-Scholes pricing model with the following weighted average
assumptions for grants in 1997 and 1996:

12.  EMPLOYEE BENEFIT PLANS:
 
    The Company maintains a defined contribution plan which covers all full time
employees of the Company who are age twenty one or older, have completed one
year of service and are not covered by a collective bargaining agreement. Profit
Sharing Contributions are at the discretion of the Board of Directors and
amounted to $203, $661 and $493, for the year ended August 31, 1997, 1996 and
1995, respectively. Administrative expense in connection with the Plan amounted
to $16, $47 and $23, for the years ended August 31, 1997, 1996 and 1995,
respectively.
 
    The Board of Directors approved an Employee Stock Purchase Plan (the ESPP)
under which 750,000 shares of Class B common stock have been reserved for
issuance to employees meeting minimum employment criteria. Employees may
participate through payroll deductions in amounts related to their base
compensation. The fair value of shares made available to any employee for
purchase under the ESPP may not exceed $25,000 in any calendar year. The
participant's purchase price is 85% of the lower of the fair market value at the
beginning or the end of the offering period. The Plan, once approved by the
shareholders, shall continue until terminated by the Board, until all of the
shares reserved for issuance under the Plan have been issued or until January 1,
2007, whichever shall first occur.

ITEM 13.  CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS.
 
LOANS TO SENIOR MANAGEMENT AND OTHER EMPLOYEES
 
    In January 1992, the Company loaned Jack L. Watts, Chairman of the Board and
Chief Executive Officer of the Company, $250,000 represented by a secured
promissory note. The note plus accrued interest was originally due in January
1993, and accrued interest at a rate equal to 2% above the Company's borrowing
rate on its revolving credit facility. In January 1997, the Board of Directors
agreed to extend until January 17, 1998 the due date of all principal and
accrued interest owing to the Company and changed the interest rate to a rate
equal to the Short Term Applicable Federal Rate for January, 1997 compounded
annually. The loan is secured by a pledge of certain shares of Class B Common
Stock, Series 1 owned by Mr. Watts. Principal plus accrued interest outstanding
at August 31, 1997 was approximately $424,000. Subsequent to the end of fiscal
1997, the Board of Directors agreed to further extend until January 17, 1999,
the due date of all principal and accrued interest owed to the Company by Mr.
Watts under the terms of the loan.
 
    The Company's policy is that it will not make loans to, or enter into other
transactions with, directors, officers or other affiliates unless such loans or
transactions are approved by a majority of the Company's disinterested
directors, may reasonably be expected to benefit the Company and, except to the
extent that loans to officers of the Company have been entered into in part in
recognition of the value of the officers' services to the Company, are on terms
no less favorable to the Company than could be obtained in arms'-length
transactions with unaffiliated third parties. From time to time, the Company has
agreed to make loans to employees of the Company who are not members of senior
management to enable such employees to purchase their residences. In this
regard, in November 1991, the Company loaned Daniel Luch, Vice President of
Research and Development, $109,000 towards the purchase of a home, and in May
1996, the Company loaned Joseph F. Jahn, formerly Vice President-Operations,
$100,000 towards the purchase of a home. Mr. Jahn left the employ of the Company
in connection with the restructuring plan implemented by the Company in fiscal
1997. The loan to Mr. Jahn was forgiven by the Company in September 1997, in
payment of certain severance amounts payable to Mr. Jahn by the Company.
 
TRANSACTIONS WITH ENTITIES AFFILIATED WITH DIRECTORS
 
    On February 14, 1997, the Company redeemed 95,238 shares of Class B Common
Stock, Series 1 held of record by LJL Cordovan Partners, L.P., an entity
controlled by Jack L. Watts. The redemption price paid by the Company was $5.25
per share.
 
                                       52
<PAGE>
    On March 31, 1997, LJL Cordovan Partners, L.P., an entity controlled by Jack
L. Watts, transferred 10,000 shares of Class B Common Stock, Series 1 to Jeffrey
Pfeffer, Ph.D., a director of the Company, at a price per share of $5.25.
 
    In June 1994, Chase Manhattan Capital Corporation purchased shares of Class
B Common Stock, Series 1 from the Company and certain insiders of Company, and
shares of Class B Common Stock, Series 2 from Robert Fleming Nominees, Ltd.
("RFNL"). In connection with these purchases, Chase Capital, RFNL and Heller
Financial, Inc., the lender under a credit facility entered into with the
Company, received certain demand and piggyback registration rights. In addition,
Chase Capital became a participant in an earlier agreement between the Company
and RFNL under which (i) the Company has the right of first offer to purchase
any shares of the Company's capital stock that either shareholder proposes to
sell to any nonrelated party and (ii) each shareholder has a right of first
offer to purchase any Class B Common Stock, Series 1 that the Company proposes
to sell. Chase Capital is also a party to certain shareholders agreements
providing for certain rights of first refusal as described below under the
heading "Shareholders Agreements." In addition, the parties to these
shareholders agreements have granted to Chase Capital certain co-sale rights to
participate in the sale by any such shareholders of more than 25% of the
outstanding shares of the Company's common stock. One of the shareholders
agreements also provides that the Company is prohibited from (i) entering into
any merger, consolidation or repurchase of capital stock, (ii) making certain
amendments to its Bylaws or Certificate of Incorporation or (iii) entering into
certain other significant transactions, without the approval of Chase Capital.
Pursuant to that agreement, Jack L. Watts, RFNL and their permitted transferees
have agreed to vote their shares in favor of a nominee of Chase Capital as a
director of the Company. Mr. Behrens is Chase Capital's current nominee.
 
    The Company retains as its legal counsel the law firm of Tomlinson Zisko
Morosoli & Maser LLP, of which Timothy Tomlinson is a general partner. For legal
services rendered during fiscal 1997, the Company paid Mr. Tomlinson's law firm
fees and expenses in the aggregate amount of $608,610. Mr. Tomlinson is a
director of the Company, a member of the Compensation Committee and an alternate
member of the Audit Committee.
 
SHAREHOLDERS AGREEMENTS
 
    A majority of the Company's shares, including shares held by Jack L. Watts
and his affiliates, are subject to shareholders agreements under which the
Company has a right of first refusal in the event of a proposed transfer of such
shares of the Company's common stock to a transferee not related to the
shareholder. In the event the Company does not exercise its right of first
refusal, the other shareholders that are parties to the agreements have similar
first refusal rights.

    "DEFICIENCY" means, for any relevant period (as set out in Section

    "LENDERS INDEBTEDNESS" means all present and future indebtedness and 
other liabilities and obligations, contingent or absolute, matured or

two Business Days before any day on which a Deficiency is anticipated by the 
Borrower or Portola U.S. or, in the case of a Deficiency that was not

Deficiency") to Portola U.S. and the Agent specifying the details and amount 
of such Deficiency.

3.  RIGHT OF THE AGENT TO GIVE NOTICE OF DEFICIENCY.  If a Deficiency shall 
occur the Agent may forthwith give a Notice of Deficiency to Portola U.S. 
(whether or not a Notice of Deficiency has been given by the Borrower 
pursuant to paragraph 2 hereof).

4.  DEFICIENCY ACTIONS.  (1)  Subject to paragraph 4(2), if at any time a 
Deficiency shall be anticipated by the Borrower or Portola U.S., or Portola 
U.S. shall receive a Notice of Deficiency, Portola U.S. shall provide for 
such Deficiency by making payment to the Borrower of an amount in Cdn. 
Dollars equal to such Deficiency (any such payment is herein called a 
"Deficiency Payment"). Each Deficiency Payment shall be made, in the case of 
a Deficiency that is anticipated by the Borrower or Portola U.S., not later 
than the day on which such Deficiency is anticipated to occur and, in any 
other case, not later than one Business Day after the related Deficiency 
Notice is received by Portola U.S. 

    (2)  Portola U.S. shall not be required to make any Deficiency Payment 
hereunder if that action would constitute an event of default by Portola U.S. 
(i) under that certain Second Amended and Restated Credit and Security 
Agreement with Heller Financial, Inc., a Delaware corporation, dated as of 
October 2, 1995, (ii) with respect to its issuance of $110,000,000, 10 3/4% 
Senior Notes under an indenture entered into with America Bank National 
Association, Firstar Trust Company, successor trustee, dated as of October 2, 
1995, (collectively, the "Loan Agreements"); provided that to the extent that 
Portola U.S. is entitled or permitted under the Loan Agreements to make 
loans, investments or payments of any kind (collectively, the "Permitted 
Payments") to any Person, Portola U.S. shall use its best efforts to make 
Deficiency Payments when required in priority to Permitted Payments to any 
other Person.

    (3)  Should Portola U.S. fail to make any Deficiency Payment required by
Section 4(1) hereof (and whether or not Portola U.S. is excused from making such
payment by Section 4(2)) then (1) such non payment shall constitute an Event of
Default under the Credit Agreement (without prejudice of any other default or
Event of Default arising thereunder), and (2) Portola U.S. shall forthwith, and
from time to time, take or refrain from taking such actions, exercise such
powers and make such elections or designations under the Loan Agreements as may
be required by the Agent in order to eliminate or mitigate any impediment under
the Loan Agreements to the ability of Portola

U.S. to address the Deficiency and repay the amounts outstanding under the 
Credit Agreement (such actions to include, if required by the Agent, making 
the Borrower a "Restricted Subsidiary" under the Loan Agreements on terms 
acceptable to the Agent and, simultaneously, repaying, or causing to be 
repaid, all amounts outstanding under the Credit Agreement) and Portola U.S. 
shall thereafter, to the extent then permitted by the Loan Agreements, and as 
required by the Agent, make the Deficiency Payment or pay the amounts 
outstanding by the Borrower to the Agent and the Lenders, provided that 
Portola U.S. shall not be required to take any action pursuant to this 
Section 4(3) which would cause or constitute an Event of Default under either 
of the Loan Agreements.

    (4)  Portola U.S. will not consent to any amendments to the Loan 
Agreements which create further or more restrictive limitations upon its 
ability to undertake any of the actions referred to in Sections 4(1) and 4(3) 
and any such further or more restrictive limitations entered into after the 
date hereof shall not be taken into account in determining the obligations of 
Portola U.S. pursuant to Sections 4(1) and 4(3).

    (5)  If it is determined that the consent of a lender or lenders under 
either or both of the Loan Agreements is required pursuant to the Loan 
Agreements in respect of any matter provided for in Sections 4(1) and 4(3). 
Portola U.S. shall, upon request of the Agent, use its best efforts to obtain 
such consent and shall advise the Agent of its progress in obtaining the 
consent.

5.  PAYMENT FOR EQUITY OR SUBORDINATED DEBT.  (1) A Deficiency Payment shall 
constitute payment by Portola U.S. to the Borrower of the issue price of 
shares of capital stock of the Borrower having such terms and conditions as 
may be agreed upon by Portola U.S. and the Borrower, and the Borrower agrees 
to duly authorize and issue such shares to Portola U.S. concurrently with the 
related Deficiency Payment being made hereunder by Portola U.S.  For greater 
certainty, however, failure by Portola U.S. and the Borrower to agree upon 
the terms and conditions of any such shares of failure by the Borrower to 
duly authorize or issue any such shares, shall not discharge, impair or 
otherwise affect the obligation of Portola U.S. to make any Deficiency 
Payment as herein required. Portola U.S. hereby authorizes and directs the 
Borrower to deliver certificates evidencing all shares issues as contemplated 
by this paragraph directly to the Agent, to be held by the Agent pursuant to 
the share pledge agreement dated as of June 16, 1995 entered into between 
Portola U.S. and the Agent with respect to the Borrower.

    (2)  A Deficiency Payment may constitute a loan by Portola U.S. to the 
Borrower and Portola U.S. acknowledges that such loan and any interest or 
fees thereon (collectively, such loan, interest and fees is hereinafter 
inferred to as the "Subordinated Indebtedness") shall for all purposes be, 
and at all times remain inferior, junior and subordinated to the Lenders 
Indebtedness.  Except as expressly agreed to by the Agent in writing, all of 
the Lenders Indebtedness shall be paid or repaid in full before any payment 
on account of, or, in respect of, the Subordinated Indebtedness (whether as 
principal, interest, fees or otherwise) is paid or repaid.
