                               PROSPECTUS SUMMARY
 
   
     The following summary is qualified in its entirety by the more detailed
information and the Consolidated Financial Statements and notes thereto
appearing elsewhere in this Prospectus. Except as otherwise noted herein,
information in this Prospectus assumes (i) no exercise of the Underwriters'
overallotment option, (ii) the conversion of all outstanding shares of Series A
Preferred Stock of the Company ("Preferred Stock") into shares of Common Stock
of the Company, (iii) the reincorporation of the Company in Delaware and (iv) a
two-for-one split of the Company's Common Stock. Unless the context otherwise
requires, the term "Company" when used herein shall mean Ocular Sciences, Inc.,
a Delaware corporation, its California predecessor and its subsidiaries.
    
 
                                  THE COMPANY
 
     Ocular Sciences is a rapidly growing manufacturer and marketer of soft
contact lenses. The Company manufactures a broad line of soft contact lenses for
annual and disposable replacement regimens. The Company believes that its lens
designs provide wearers with a higher level of comfort and greater ease of
handling than those of its leading competitors. The Company's manufacturing
technologies permit consistent, cost-effective reproduction of these designs,
allowing the Company to offer its lenses at competitive prices. In addition, the
Company has implemented marketing strategies designed to assist eyecare
practitioners, both in independent practice and in retail chains, in retaining
their patients and monitoring their patients' ocular health, thereby providing a
significant incentive for practitioners to prescribe the Company's lenses.
Furthermore, the Company has continuously focused on lowering its
non-manufacturing costs, or "cost-to-serve," enabling it to increase its
profitability and its flexibility to reduce prices. To minimize its
cost-to-serve, the Company utilizes a telemarketing sales force and directs its
marketing efforts toward eyecare practitioners rather than consumers.
 
     Industry analysts estimate that approximately 50% of the world's population
need some type of vision correction. In the United States alone, over 130
million people require some form of vision correction. The United States
currently represents the world's largest market for contact lenses, with
approximately 26 million people, or 20% of those requiring vision correction,
wearing contact lenses according to estimates by industry analysts. The soft
contact lens market is characterized by increasing lens consumption. The number
of soft contact lenses sold in the United States has increased at a compound
annual growth rate of approximately 20% from 1985 to 1995, according to Health
Products Research, a market research firm, largely as a result of the
introduction in 1988 of soft contact lenses for disposable replacement regimens.
This increase in unit sales has provided manufacturing economies of scale that,
together with heightened competition among eyecare practitioners, has led to
significant reductions in average retail prices for soft contact lenses. Despite
the decline in per unit prices, wearers' annual expenditures for lenses have
increased as they have shifted to more frequent replacement regimens. The
Company believes that sales in many international markets will grow at faster
rates than the United States market and that this growth will be driven
principally by an increase in the number of contact lens wearers, which
currently is significantly lower than that in the United States, as the
availability of low-priced soft contact lenses increases.
 
     The Company believes, based on a 1994 study sponsored by the American
Academy of Ophthalmology and management's recent experience in the eyecare
industry, that the eyecare profession suffers from a surplus of practitioners
and believes that the resulting competitive pressure has been exacerbated by the
increased prevalence of retail optical chains and mass merchandisers that
provide eyecare services. The typical eyecare practitioner in both the private
practice and retail chain channels depends heavily on sales of products, such as
contact lenses and eyeglasses. The Company believes, based on a 1996 industry
survey, that the typical optometric practice realizes approximately two-thirds
of its revenue from sales of optical products, such as contact lenses and
eyeglasses. Since the need for vision correction is chronic, repeat sales of
contact lenses can provide the practitioner with a recurring, predictable
revenue base. However, with the advent of disposable replacement regimens and
the availability of nationally advertised lens brands through many competing
channels of distribution, including mail-order and pharmacies, the prescribing
practitioner risks losing recurring sales to alternate distribution channels.
 
     The Company believes that practitioners can increase their patient
retention and provide better ongoing patient care by providing
competitively-priced, high-quality products that are differentiated by brand
from those provided by competing distribution channels. Accordingly, the Company
has successfully implemented a
 
                                        4
<PAGE>   6
 
strategy to address the needs of eyecare practitioners. The Company markets its
lenses solely to eyecare practitioners, both in private practice and in retail
optical chains, rather than to consumers. The Company believes that focusing on
the eyecare practitioner, who strongly influences the selection of the brand of
contact lenses worn by the patient, is critical to its ability to market contact
lenses successfully. The Company does not sell to mail-order companies,
pharmacies or other distribution channels that do not provide the eyecare
services necessary to maintain overall ocular health.
 
     Over the last five years, the Company has established itself as a leader in
the spherical, non-specialty annual replacement segment of the United States
market with a market share estimated at 25% in 1996, based on unit sales. Since
its introduction of lenses for weekly disposable replacement regimens in 1993,
the Company has steadily increased its share of this growing market, reaching
approximately 8% of total unit sales in the United States during the second half
of 1996, based on data published by the Contract Lens Institute. The Company's
overall unit sales have increased at a compound annual growth rate of
approximately 81% since 1992, primarily due to increased sales of its lenses for
weekly disposable replacement regimens. During the same period, while the
overall average selling prices of all of the Company's lenses declined 50%, the
Company reduced its per unit production costs by approximately 64% by spreading
its relatively fixed manufacturing and operating costs over higher production
volumes, and by improving its manufacturing and packaging processes. As a
result, from 1992 to 1996, the Company's net sales and operating income
(excluding non-recurring charges in 1992) have increased at compound annual
growth rates of approximately 53% and 100%, respectively, while its operating
margins improved from 6.6% to 19.3%. The Company expects that the overall
average selling price that it realizes across its products will continue to
decline over time and does not expect there to be significant growth in its
sales of lenses for annual replacement. The Company does not believe that its
recent net sales and operating income growth rates are indicative of its
long-term growth rates.
 
STRATEGY
 
     The Company believes that, by continuing to pursue its strategy focused on
addressing the needs of the eyecare practitioner, it will be well-positioned to
increase its sales and its share of the growing disposable lens market segment.
The principal elements of the Company's strategy include:
 
          Focus Marketing on Eyecare Practitioners. The Company's sales and
     marketing efforts are directed at eyecare practitioners because the
     practitioner strongly influences the brand of lenses purchased by the
     patient. The Company advertises and promotes its products solely to
     practitioners rather than to consumers. In addition, the Company does not
     sell its lenses to mail-order companies, pharmacies and other distribution
     channels that do not provide the eyecare services necessary to confirm lens
     fit and monitor ocular health. By bar-coding each disposable unit shipped,
     the Company can identify any diversion of its lenses to non-eyecare
     practitioner channels. The Company structures its branding and marketing
     strategies so that the patient will be more likely to refill prescriptions
     from the practitioner or retail chain from whom he or she received the
     initial prescription. As a result, the Company believes that it assists
     eyecare practitioners in retaining patient reorders and improves
     practitioners' ability to monitor their patients' ongoing ocular health,
     thereby providing a significant incentive for practitioners to prescribe
     the Company's lenses.
 
          Employ Unique Brand Segmentation by Channel. The high-volume use of
     lenses for disposable replacement regimens has resulted in increased
     mass-market advertising of competing products and intensified competition
     across distribution channels. Unlike its larger competitors, which promote
     nationally advertised consumer brands across multiple distribution
     channels, the Company advertises and promotes its lenses for disposable
     replacement regimens under specific brand names for the private practice
     channel and other brand names for the retail chain channel. The Company
     also provides private label brands for its larger customers. Branding by
     distribution channel creates brand exclusivity and allows practitioners to
     differentiate lenses sold by them from lenses sold through competing
     channels, providing them with a greater ability to retain their patients'
     prescription refill business. The Company believes that, as a result, its
     channel-specific branding has become increasingly valuable to eyecare
     practitioners. By promoting the repeat purchase of lenses from the
     prescribing practitioner, the Company believes that its marketing
     strategies increase patient satisfaction and thereby encourage long-term
     loyalty to its products, while also motivating practitioners to prescribe
     its lenses.
 
          Produce Superior Performing Products. The Company believes that its
     contact lenses are superior in performance to those of its major
     competitors in terms of comfort and ease of handling. The
 
                                        5
<PAGE>   7
 
     Company's advanced dry cast molding process and sophisticated lens designs
     maximize wearers' comfort and improve shape retention of lenses, making
     them easier for wearers to handle. In addition, the Company's lenses are
     designed and manufactured to provide fitting characteristics similar to
     competitors' lenses. In general, this interchangeability enables the
     practitioner to switch a patient to the Company's lenses without extensive
     refitting time. These advantages enable the Company to market its lenses to
     eyecare practitioners for both existing and new contact lens wearers.
 
          Emphasize Low-Cost Efficient Manufacturing. With the growth of the
     high-volume disposable market segment, low-cost, scalable manufacturing has
     become increasingly important. The Company's dry cast molding technology
     allows it to manufacture high-quality lenses efficiently. With dry cast
     molding, the Company has been able to reduce its manufacturing costs per
     lens by approximately 64% over the last three years while increasing its
     production volumes by approximately 470%. The Company believes that the
     increased unit volumes resulting from the growing disposable lens market
     and continued investment in automation and capacity will enable it to
     further reduce per unit production costs and increase production volumes.
 
          Minimize Cost-to-Serve. A substantial portion of the Company's costs
     consists of the costs required to sell and market lenses and to take and
     fill an order. The Company focuses on lowering these non-manufacturing
     costs, or "cost-to-serve," in order to increase its profitability and its
     flexibility to reduce prices. The Company's primary means of minimizing
     cost-to-serve are its use of telemarketing rather than a traditional direct
     sales organization and its use of advertising targeted to practitioners
     rather than to consumers. This strategy differentiates the Company from its
     competitors, and the Company believes that the cost of its average sales
     call is substantially lower than that of its competitors that rely on field
     sales representatives, as the Company's inside sales personnel can make
     more calls per day at a lower annual cost per salesperson. In addition,
     unlike its leading competitors, which market their products to consumers
     through expensive mass-media campaigns, the Company controls its operating
     expenses by directing its marketing solely to the eyecare practitioners who
     prescribe contact lenses. In addition, the Company is investing in
     increased automation in its distribution operations in order to maintain
     its low cost-to-serve.
 
          Expand Internationally Through Strategic Relationships. The Company
     believes that many international markets for soft contact lenses will grow
     at faster rates than the United States market and that this growth will be
     driven by increased availability of low-priced disposable lenses in
     developed markets such as Europe, Japan and Canada and by increased
     disposable income in emerging markets such as Asia and Latin America.
     However, many markets outside the United States do not have the level of
     demand necessary for local manufacturers to achieve the economies of scale
     required for low-cost lens production. Consistent with its strategy of
     minimizing cost-to-serve, the Company's international growth strategy is to
     establish strategic distribution and marketing relationships with regional
     optical companies, such as the contact lens division of the Carl Zeiss
     Company in Europe and Seiko Contactlens, Inc. in Japan, to capitalize on
     their existing market presence, customer relationships and local
     infrastructure. The Company believes that, as a result, it can target
     growing international markets effectively without significant investment in
     direct operations.
 
BACKGROUND
 
     The Company was founded in 1985 and was principally a distributor of
contact lenses until 1992. In September 1992, the Company began manufacturing
operations by acquiring Precision Lens Laboratories Ltd. ("PLL"), a United
Kingdom-based company and, until the acquisition, the primary supplier of the
Company's lenses. This acquisition provided the Company with the facilities and
technology to manufacture high-quality contact lenses. In October 1992, the
Company acquired the contact lens business of Allergan, Inc. in North and South
America, which had been operating under the name American Hydron ("American
Hydron"). This acquisition provided the Company with a significantly expanded
customer base, an additional line of contact lens products and a manufacturing
facility in Puerto Rico.
                            ------------------------
 
     The Company was incorporated under the name O.S.I. Corporation in
California in 1985 and will reincorporate in Delaware prior to the consummation
of this offering. The Company's principal executive offices are located at 475
Eccles Avenue, South San Francisco, California 94080, and its telephone number
is (415) 583-1400.

                                  RISK FACTORS
 
     In addition to the other information in this Prospectus, the following
factors should be considered carefully in evaluating an investment in the shares
of Common Stock offered hereby. This Prospectus contains forward-looking
statements that involve risks and uncertainties. The Company's actual results
may differ materially from the results discussed in such forward-looking
statements. Factors that may cause such a difference include, but are not
limited to, those discussed below, in the section entitled "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and
elsewhere in this Prospectus.
 
     Intense Competition. The market for soft contact lenses is intensely
competitive and is characterized by decreasing prices for many products. The
Company's products compete with products offered by a number of larger companies
including the Vistakon division of Johnson & Johnson ("Johnson & Johnson"),
Ciba-Geigy Corporation ("Ciba-Geigy"), Bausch & Lomb, Inc. ("Bausch & Lomb") and
Wesley Jessen VisionCare, Inc. ("Wesley Jessen"). Most of the Company's
competitors have substantially greater financial, manufacturing, marketing and
technical resources, greater market penetration and larger manufacturing volumes
than the Company. Among other things, these advantages may afford the Company's
competitors greater ability to manufacture large volumes of lenses, reduce
product prices and influence customer buying decisions. The Company believes
that certain of its competitors are expanding, or are planning to expand, their
manufacturing capacity, and are implementing new, more automated manufacturing
processes, in order to support anticipated increases in volume. As many of the
costs involved in producing contact lenses are relatively fixed, if a
manufacturer can increase its volume, it can generally reduce its per unit costs
and thereby increase its flexibility to reduce prices. In addition, competitors
may reduce prices to achieve the sales volumes necessary to utilize their
increased capacity. Price reductions by competitors could make the Company's
products less competitive, and there can be no assurance that the Company would
be able to reduce its prices in response. The Company's ability to respond to
competitive pressures by decreasing its prices without adversely affecting its
gross margins and operating results will depend on its ability to decrease its
costs per lens. Any significant decrease in the Company's costs per lens will
depend, in part, on the Company's ability to increase its sales volume and
production capacity. There can be no assurance that the Company will be able to
continue to increase its sales volume or reduce its per unit production costs.
In response to competition, the Company may also increase cooperative
merchandising allowances or otherwise increase spending, which may adversely
affect its business, financial condition and results of operations. The failure
of the Company to respond to competitive pressures, and particularly price
competition, in a timely manner would have a material adverse effect on the
Company's business, financial condition and results of operations. See
"-- Manufacturing Capacity Constraints; Risks Associated with Expansion and
Automation of Manufacturing Operations."
 
     The market for contact lenses is shifting from lenses marketed for annual
replacement regimens, where the Company has significant experience and a leading
market position, to lenses for disposable replacement regimens, where the
Company is less experienced and has a significantly smaller market share. The
disposable lens segment is particularly competitive and price-sensitive and is
currently dominated by the Acuvue product produced by Johnson & Johnson. The
Company believes that the per unit production costs of Johnson & Johnson and
certain of the Company's other competitors are currently lower than those of the
Company. A significant price reduction by Johnson & Johnson or certain of the
Company's other competitors could limit or reduce the Company's market share in
the disposable lens segment and, as a result, could materially adversely affect
the Company's business, financial condition and results of operations. In
addition, the lenses currently offered in the United States by the Company in
the disposable lens segment are marketed for weekly and monthly replacement
regimens. Certain of the Company's competitors have introduced lenses for daily
replacement at lower prices than their current weekly and bi-weekly disposable
lenses. The Company's ability to enter and to compete effectively in the market
for daily disposable lenses will depend in large part upon the Company's ability
to expand its production capacity and reduce its per unit production costs.
Additionally, as contact lenses for different replacement regimens are often
similar, the ability of competitors to reduce their per unit costs for daily
disposable lenses may also permit them to reduce their costs for lenses marketed
for other replacement regimens. Such reductions, if not matched by the Company,
could significantly adversely impact the Company's ability to compete over a
much broader level of products. See "-- Dependence on Single Product Line; Need
to Increase Sales of Lenses for Disposable Replacement Regimens."
 
                                        8
<PAGE>   10
 
     The Company also encounters competition from manufacturers of eyeglasses
and from alternative technologies, such as surgical refractive procedures
(including new refractive laser procedures such as PRK, or photorefractive
keratectomy, and LASIK, or laser in situ keratomileusis). If surgical refractive
procedures become increasingly accepted as an effective and safe technique for
permanent vision correction, they could substantially reduce the demand for
contact lenses by enabling patients to avoid the ongoing cost and inconvenience
of contact lenses. Accordingly, there can be no assurance that these procedures,
or other alternative technologies that may be developed in the future, will not
cause a substantial decline in the number of contact lens wearers and thus have
a material adverse effect on the Company's business, financial condition and
results of operations. See "Business -- Competition."
 
     Manufacturing Capacity Constraints; Risks Associated with Expansion and
Automation of Manufacturing Operations. The Company's success will depend upon
its ability to increase its production volume on a timely basis while
maintaining product quality and lowering per unit production costs.
Manufacturers often encounter difficulties in increasing production volumes,
including problems involving delays, quality control and shortages of qualified
personnel. Any significant increase in production volume will require that the
Company increase its manufacturing capacity.
 
     The Company intends to add new, highly automated production lines at its
facilities in the United Kingdom and Puerto Rico to increase its manufacturing
capacity and reduce its per unit manufacturing costs. However, there can be no
assurance that the Company will be able to implement these automated lines on a
timely basis or that the new automated lines will operate as efficiently as
expected. The Company could encounter significant difficulties in implementing
these automated lines. For example, suppliers could miss their equipment
delivery schedules, the efficiency of the new production lines could improve
less rapidly than expected, if at all, or the equipment or processes could
require redesigning after installation. In addition, these new production lines
will involve processes and equipment with which the Company and its personnel
are not experienced. Difficulties experienced by the Company in automating its
manufacturing facilities could impair the Company's ability to reduce its per
unit production costs and to compete in the disposable lens market and,
accordingly, could have a material adverse effect on the Company's business,
financial condition and results of operations. In addition, the installation of
these highly automated production lines in Puerto Rico could increase the
Company's tax rate if it results in a significant reduction in the Company's
labor costs in Puerto Rico in relation to its Puerto Rican earnings.
 
     The Company currently expects to invest approximately $44.0 million in
capital expenditures on automated production lines in the United Kingdom and
Puerto Rico through the year 2000. The Company intends to finance such capital
expenditures with approximately $22.0 million of the net proceeds of this
offering and with net cash (if any) from operations. If net cash from operations
is insufficient to fund such expenditures, the Company intends to utilize
borrowings under its credit facilities. No assurances can be given as to the
availability of such net cash from operations or borrowings, and if such funds
are not available, the Company could be required to curtail the installation of
the automated lines.
 
     The Company is currently experiencing space constraints at its Puerto Rican
facility, which is now operating at or near capacity. As a result, the Company
is in the process of negotiating a lease for a new, larger facility to be
constructed to the Company's specifications. There can be no assurance that the
Company will be able to secure this space in a timely manner, if at all. If
space is secured, the facility must be constructed, and the Company will be
required to develop and install production lines that comply with applicable
laws including the Federal Food, Drug and Cosmetic Act (the "FDC Act") and
requirements of the U.S. Food and Drug Administration (the "FDA") pertaining to
current good manufacturing practices ("GMP"). Before any new facility for
manufacturing contact lenses can begin production, it must be inspected by the
FDA for compliance with GMP, and the inspection and approval process could
significantly delay the Company's ability to begin production in this new
facility. The development and construction of a new manufacturing facility is
subject to significant risks and uncertainties, including cost estimation errors
and overruns, construction delays, weather problems, equipment delays or
shortages, production start-up problems and other factors. As many of such
factors are beyond the Company's control, the Company cannot predict the length
of any such delays, which could be substantial. Accordingly, while the Company
expects to begin construction of the new facility during the third quarter of
1997, there can be no assurances as to when it will complete
 
                                        9
<PAGE>   11
 
construction and commence production. Given the long lead times associated with
constructing a new facility which can involve up to 18 months of development and
construction, as well as delays while seeking FDA approval, the Company will
incur substantial cash expenditures before production of commercial volumes of
contact lenses is achieved at its planned new facility in Puerto Rico.
Furthermore, the Company's development of a new facility will result in new
fixed and operating expenses, including substantial increases in depreciation
expense that will increase the Company's cost of sales. If revenue levels do not
increase sufficiently to offset these new expenses, the Company's operating
results could be materially adversely affected. There can be no assurance that
the Company will not encounter unforeseen difficulties, costs or delays in
constructing and equipping the new manufacturing facility in Puerto Rico, in
relocating operations to the new facility or in commencing production at the new
facility. Any such difficulties or delays would limit the Company's ability to
increase production volume and lower per unit costs (and consequently prices),
would limit the Company's ability to compete in the disposable lens market and,
accordingly, could have a material adverse effect on the Company's business,
financial condition and results of operations.
 
     The Company has in the past experienced, and may in the future experience,
delays in its ability to fill customer orders for certain products on a timely
basis because of limits on its production capacity. Significant delays in
filling orders over an extended period would damage customer relations, which
would materially adversely affect the Company's business, financial condition
and results of operations. The production schedules for each of the Company's
products are based on forecasts of customer demand for such products, and the
Company has only limited ability to modify short-term production schedules. If
the Company were to underestimate materially the demand for any of its products,
it would not be able, on a short-term basis, to satisfy such demand fully. The
ability of the Company to estimate demand may be less precise during periods of
rapid growth or with respect to new products. The failure of the Company to
forecast its requirements accurately could lead to inventory shortages or
surpluses that could adversely affect results of operations and lead to
fluctuations in quarterly operating results. See "Business -- Manufacturing."
 
     Risk of Trade Practice Litigation; Changes in Trade Practices. The contact
lens industry has been the subject of a number of class action and government
lawsuits and government investigations in recent years. In December 1996, over
twenty states sued three of the Company's largest competitors, as well as
certain eyecare practitioners and trade organizations. The suit alleges, among
other things, a conspiracy among such persons to violate antitrust laws by
refusing to sell contact lenses to mail-order and other non-practitioner contact
lens providers, so as to reduce competition in the contact lens industry. A
similar lawsuit was filed by the State of Florida in 1994 and may go to trial in
1997, and several similar class action lawsuits were also filed in 1994. It has
recently been announced that one of the defendants in such suits has agreed to
settle the lawsuits as to itself by agreeing to sell contact lenses to
mail-order and other alternative distribution channels, and to make substantial
cash and product rebates available to consumers. See "Business -- Sales and
Marketing." In an unrelated matter, one of the Company's largest competitors was
sued in a class action lawsuit brought in the Federal District Court in the
Northern District of Alabama in 1994 (the "Alabama Lawsuit"). This suit alleged
that the defendant engaged in fraudulent and deceptive practices in the
marketing and sale of contact lenses by selling identical contact lenses, under
different brand names and for different replacement regimens, at different
prices. The defendant subsequently modified certain of its marketing practices
and ultimately settled the lawsuit in August 1996 by making substantial cash and
product payments available to consumers. See "Business -- Products." Although
the Company has not been named in any of the foregoing lawsuits, the Company
from time to time receives claims or threats similar to those brought against
its competitors, and in one circumstance a suit was filed against the Company
making allegations similar to those made in the Alabama Lawsuit, which suit was
dismissed without prejudice for non-substantive reasons. There can be no
assurance that the Company will not face similar actions relating to its
marketing and pricing practices or other claims or lawsuits in the future. The
defense of any such action, lawsuit or claim could result in substantial expense
to the Company and significant diversion of attention and effort by the
Company's management personnel. There can be no assurance that any such lawsuit
would be settled or decided in a manner favorable to the Company, and a
settlement or adverse decision in any such action, lawsuit or claim could have a
material adverse effect on the Company's business, financial condition and
results of operations.

     In addition to the foregoing lawsuits, there is substantial federal and
state governmental regulation related to the prescribing of contact lenses.
These regulations relate to who is permitted to prescribe and fit contact
lenses, the prescriber's obligation to provide prescriptions to its patients,
the length of time a prescription is valid, the ability or obligation of
prescribers to prescribe lenses by brand rather than by generic equivalent or
specification, and other matters. Although these regulations primarily affect
contact lens prescribers, and not manufacturers or distributors of lenses such
as the Company, changes in these regulations, or their interpretation or
enforcement, could adversely affect the effectiveness of the Company's marketing
strategy to eyecare practitioners, most notably the effectiveness of the
Company's channel-specific and private label branding strategies. See
"Business -- Strategy." Additionally, given the Company's strategic emphasis on
focusing its marketing efforts on eyecare practitioners, the Company may be more
vulnerable than its competitors to changes in current trade practices. Finally,
although cost controls or other requirements imposed by third party health-care
payors such as insurers and health maintenance organizations have not
historically had a significant effect on contact lens prices or distribution
practices, this could change in the future, and could adversely affect the
Company's business, financial condition and results of operations. Adverse
regulatory or other decisions affecting eyecare practitioners, or material
changes in the selling and prescribing practices for contact lenses, could have
a material adverse effect on the Company's business, financial condition and
results of operations. See "Business -- Government Regulation."
 
     Dependence on Single Product Line; Need to Increase Sales of Lenses for
Disposable Replacement Regimens. All of the Company's net sales to date have
been attributable to the Company's sale of soft contact lenses. Should the
demand for the Company's soft contact lenses decline due to increased
competitive pressures, changes in consumer preferences, the inability of the
Company to respond to reduced prices by its competitors, the advent of
alternative technologies for correcting vision or other factors, the Company's
business, financial condition and results of operations would be materially
adversely affected.
 
     A substantial portion of the Company's net sales to date (and, through
1994, a majority of the Company's net sales) have been attributable to the
Company's sales of soft contact lenses for annual replacement regimens. The U.S.
market for contact lenses for annual replacement regimens has been marked by
reduced overall demand in recent years. The Company expects that this segment of
the market for contact lenses for annual replacement regimens will continue to
contract in its major geographic markets as the market for contact lenses for
disposable replacement regimens continues to expand. The Company, a relatively
recent entrant in the market for lenses for disposable replacement regimens,
introduced its first product marketed for weekly replacement in September 1993.
The Company's success depends on both continued growth of this market and
increased penetration of this market by the Company's products. As the number of
wearers of contact lenses in the U.S. has not grown significantly in recent
years, and has decreased in some periods, increased market penetration by the
Company will require that wearers of competing products switch to the Company's
products. The Company anticipates that prices for its products targeted for
disposable replacement regimens will decline in the future. There can be no
assurance that the Company's contact lenses for disposable replacement regimens
will achieve widespread consumer acceptance, or that net sales or net income
from the sale of the Company's lenses for disposable replacement regimens will
be sufficient to offset the decline in the Company's net sales or net income
from its contact lenses for annual replacement regimens, which have higher
prices and gross margins. Any such failure to achieve market acceptance or to
capture a significant share of the disposable contact lens market segment would
impair the Company's ability to reduce its per unit production costs and would
have a material adverse effect on the Company's business, financial condition
and results of operations. See "-- Intense Competition," "Management's
Discussion and Analysis of Financial Condition and Results of Operations,"
"Business -- Products" and "Business -- Competition."
 
     Risk of New Products and Technological Change. The Company does not
allocate substantial resources to new product development and has historically
leveraged or licensed the technology developments of others. The Company
believes that many of its competitors have invested, and will continue to
invest, substantial amounts in developing new products and technologies, and
there can be no assurance that the Company's competitors do not have or will not
develop new products and technologies that could render the Company's products
less competitive. For example, Johnson & Johnson has recently introduced lenses
for disposable replacement regimens with an ultraviolet light inhibitor, which
could increase the appeal of its products. The
 
                                       11
<PAGE>   13
 
Company intends to develop a similar feature, but has only recently begun the
design process and no assurance can be given as to when or whether the Company
will be able to offer this feature. In addition, it has been reported that
Ciba-Geigy and others are seeking to develop lenses based on new polymers that
may significantly increase the period over which the lens may be left in the
eye. There can be no assurance that the Company will be able to sufficiently
utilize technology developed by third parties in order to remain competitive.
Any failure by the Company to stay current with its competitors with regard to
new product offerings and technological changes and to offer products that
provide performance that is at least comparable to competing products would have
a material adverse effect on the Company's business, financial condition and
results of operations. See "-- Dependence on Single Product Line; Need to
Increase Sales of Lenses for Disposable Replacement Regimens" and
"Business -- Research and Development."
 
   
     Fluctuations in Operating Results; Seasonality; Decreasing Average Sales
Prices. The Company's quarterly operating results have varied significantly in
the past and are likely to vary significantly in the future based upon a number
of factors. The Company's quarterly results can be affected significantly by
pricing changes by the Company or its competitors, the Company's ability to
increase manufacturing capacity efficiently and to reduce per unit manufacturing
costs, the time and costs involved in expanding existing distribution channels
and establishing new distribution channels, discretionary marketing and
promotional expenditures such as cooperative merchandising allowances paid to
the Company's customers, timing of the introduction of new products by the
Company or its competitors, inventory shortages, timing of regulatory approvals
and other factors. The Company's customers generally do not have long-term
commitments to purchase products and products are generally shipped as orders
are received. Consequently, quarterly sales and operating results depend
primarily on the volume and timing of orders received during the quarter, which
are difficult to forecast. A significant portion of the Company's operating
expenses are relatively fixed, and planned expenditures are based on sales
forecasts. If sales levels fall below expectations, operating results are likely
to be materially adversely affected. In particular, net income may be
disproportionately affected because only a small portion of the Company's
expenses varies with net sales in the short term. In response to competition,
the Company may reduce prices, increase cooperative merchandising allowances or
otherwise increase marketing expenditures, and such responses may adversely
affect the Company's business, financial condition and results of operations.
Due to the foregoing factors, the Company believes that period-to-period
comparisons of its results of operations are not necessarily meaningful and
should not be relied upon as indications of future performance. Further, it is
likely that in some future quarter the Company's net sales or operating results
will be below the expectations of public market analysts and investors. In such
event, the price of the Company's Common Stock would likely be materially
adversely affected.
    
 
     The Company's historical sales have exhibited significant seasonality, with
the third and fourth quarters having the highest net sales in any year and the
first quarter of the following year having lower net sales than the preceding
two quarters. The Company believes that the seasonality of its quarterly results
is primarily due to consumer buying habits. The Company believes that the
historical increases in sales of its products in the third and fourth quarters
have been due to late summer (back-to-school) purchases by consumers and to
higher traffic in the fourth quarter through malls and mass merchandisers with
optical outlets. The Company further believes that the historical decline in the
first quarter has been due to reduced consumer buying in the post-holiday
season. In addition, due to the relatively high proportion of the Company's
fixed costs to its total costs, the Company's level of profitability has
historically increased significantly with increasing sales volumes, resulting in
disproportionately better results in the second half of each year. There can be
no assurance that these patterns will not continue in future years although the
pattern may be somewhat less pronounced if the Company continues to increase the
proportion of sales represented by more frequently replaced lenses for
disposable replacement regimens.
 
     The Company expects that the overall average selling price that it realizes
across its products will decline over time because of (i) shifts in the
Company's product mix from lenses for annual replacement regimens to lenses for
disposable replacement regimens and, within its disposable lenses, to lenses
that are replaced more frequently, (ii) decreases in the prices of lenses for
disposable replacement regimens and (iii) increases in products sold
internationally through distributors at prices lower than direct sales prices in
the United States. The Company does not expect there to be significant growth in
its sales of lenses for annual replacement.
 
                                       12
<PAGE>   14
 
Accordingly, the Company will need to continue to reduce its per unit production
costs through increased automation, increased volume and reduced packaging costs
in order to improve, or even to maintain, its gross margins, and the Company
does not believe that its recent net sales and operating income growth rates are
indicative of the Company's long-term growth rates. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations."
 
     Risks Relating to International Operations; Need to Increase Sales in
International Markets. In 1995, 1996 and the first six months of 1997, the
Company's international sales represented 17.6%, 18.1% and 20.5%, respectively,
of the Company's net sales. In addition, a substantial portion of the Company's
products are manufactured in the United Kingdom. As a result, the Company's
business is subject to the risks generally associated with doing business
abroad, such as foreign consumer preferences, disruptions or delays in
shipments, changes in currency exchange rates, longer accounts receivable
payment cycles and greater difficulties in collecting accounts receivable,
foreign tax laws or tariffs, political unrest and changing economic conditions
in countries in which the Company's products are sold or manufacturing
facilities are located. These factors, among others, could adversely affect the
Company's ability to sell its products in international markets, as well as its
ability to manufacture its products. If any such factors were to render the
conduct of business in a particular country undesirable or impractical, there
could be a material adverse effect on the Company's business, financial
condition and results of operations. The Company and its representatives, agents
and distributors are also subject to the laws and regulations of the foreign
jurisdictions in which they operate or in which the Company's products are sold.
The regulation of medical devices in a number of jurisdictions, particularly in
the European Union, continues to develop, and there can be no assurance that new
laws or regulations will not have a material adverse effect on the Company's
business, financial condition and results of operations.
 
     A substantial portion of the Company's sales and expenditures is collected
or paid in currencies other than the U.S. dollar. Therefore, the Company's
operating results are affected by fluctuations in foreign currency exchange
rates. Although the impact of exchange rate fluctuations on the Company's
results of operations have not been material in the past three years, there can
be no assurance that in the future exchange rate movements will not have a
material adverse effect on the Company's sales, gross profit, operating expenses
or foreign currency exchange gains and losses. In the six months ended June 30,
1997, the Company had an exchange gain of $59,000, primarily relating to changes
in exchange rates between the U.S. dollar and the U.K. pound sterling.
 
     The Company's continued growth is dependent on the expansion of
international sales of its products. This expansion will involve operations in
markets with which the Company is not experienced and there can be no assurance
that the Company will be successful in capturing a significant portion of these
markets for contact lenses. In addition, the Company will not be able to market
and sell its products in certain international markets, such as Japan, until it
obtains regulatory approval. The failure of the Company to increase its
international sales substantially could have a material adverse effect on the
Company's business, financial condition and results of operations.
 
     The Company will depend on distributors to market and sell its contact
lenses and, in some cases, to obtain necessary regulatory approvals in a number
of international markets, including Europe and Japan. There can be no assurance
that these distributor relationships will be successful, that other existing
distributor relationships will be maintained or that any disruptions in such
relationships will not have a material adverse effect on the Company's business,
financial condition and results of operations. See "Business -- Sales and
Marketing."
 
     Uncertain Ability to Manage Growth; Risks Associated with Implementation of
New Management Information Systems. The Company has experienced rapid growth in
recent years. Continued rapid growth may place a significant strain on
management, operational infrastructure, working capital and financial and
management control systems. Growth in the Company's business has required, and
is expected to continue to require, significant personnel management and other
infrastructure resources. The Company's ability to manage any future growth
effectively will require it to attract, train, motivate and manage new employees
successfully, to integrate new employees into its overall operations and to
continue to improve its operational,
 
                                       13
<PAGE>   15
 
financial and management information systems. The Company is in the process of
replacing its management information systems. The new systems will significantly
affect many aspects of the Company's business, including its manufacturing,
sales and marketing, and accounting functions, and the successful implementation
of these systems will be important to facilitate future growth. Implementation
of the new management information systems could cause significant disruption in
operations. If the Company is not successful in implementing its new systems or
if the Company experiences difficulties in such implementation, the Company
could experience problems with the delivery of its products or an adverse impact
on its ability to access timely and accurate financial and operating
information. See "Business -- Employees."
 
     Risks Associated with Interruption of Manufacturing Operations. The Company
manufactures substantially all of the products it sells. As a result, any
prolonged disruption in the operations of the Company's manufacturing
facilities, whether due to technical or labor difficulties, destruction of or
damage to any facility or other reasons, could have a material adverse effect on
the Company's business, financial condition and results of operations. In this
regard, one of the Company's principal two manufacturing facilities is located
in Puerto Rico and is thus exposed to the risks of damage from hurricanes. To
date, hurricanes have not materially affected the Company's operations in Puerto
Rico. However, if this facility were to be out of production for an extended
period, the Company's business, financial condition and results of operation
would be materially adversely affected. See "Business -- Manufacturing."
 
     Dependence on Trademarks, Patent Licenses and Trade Secrets; Risk of
Intellectual Property Infringement. The Company has numerous trademark
registrations in the United States, Europe and other foreign countries. The
Company believes that its trademarks have significant value and are instrumental
to its ability to create and sustain demand for its products and to implement
its channel-based branding strategy. The Company believes that there are no
currently pending challenges to the use or registration of any of the Company's
material trademarks. There can be no assurance, however, that the Company's
trademarks do not or will not violate the proprietary rights of others, that
they would be upheld if challenged or that the Company would, in such an event,
not be prevented from using its trademarks, any of which could have a material
adverse effect on the Company's business, financial condition and results of
operations.
 
     From time to time, the Company discovers products in the marketplace that
infringe on trademark rights held by the Company. If the Company is unsuccessful
in challenging a third party's trademark infringement, continued sales of such
product could adversely affect the Company's marketing strategy, which relies
heavily on the Company's proprietary trademarks, and could have a material
adverse effect on the Company's business, financial condition and results of
operations.
 
     The Company currently relies on a licensed patent for a significant element
of the dry cast molding technology used in the production of its products. This
license is non-exclusive, and therefore this patented process may be licensed to
the Company's competitors. Also, the patent owners have a significant interest
in a United Kingdom company that competes with the Company in certain markets
and that was, until recently, contractually prohibited from selling lenses in
the United States. See "Certain Transactions -- OSL Acquisition and Related
Litigation." The Company also relies on non-exclusive licenses to certain design
patents for its toric and bifocal contact lenses, and these licenses limit the
Company's sales of products using the licensed technology to the Americas. The
Company owns no patents and has no patent applications pending. Certain of the
Company's competitors have significant patent portfolios. To the extent the
Company desires or is required to obtain additional licenses to patents or
proprietary rights of others, there can be no assurance that any such licenses
will be available on terms acceptable to the Company, if at all. The inability
of the Company to obtain any of these licenses could result in an inability to
make or sell products or reductions or delays in the introduction of new
products to meet consumer preferences. Any such prohibitions, reductions or
delays in the introduction of such products could have a material adverse effect
on the Company's business, financial condition and results of operations.
 
     In addition to trademarks and patent licenses, the Company owns certain
trade secrets, copyrights, know-how and other intellectual property. The Company
seeks to protect these assets, in part, by entering into confidentiality
agreements with certain of its business partners, consultants and vendors. There
can be no assurance that these agreements will not be breached, that the Company
will have adequate remedies for any
 
                                       14
<PAGE>   16
 
such breach or that the Company's trade secrets and other intellectual property
will not otherwise become known or independently developed by others and thereby
become unprotected. Furthermore, no assurance can be given that competitors will
not independently develop substantially equivalent proprietary information and
techniques or otherwise gain access to the Company's proprietary technology or
that the Company can meaningfully protect its rights in unpatented proprietary
technology.
 
     The defense and prosecution of intellectual property suits and related
administrative proceedings are both costly and time-consuming. Litigation may be
necessary to protect trade secrets or know-how owned by the Company or to
determine the enforceability, scope and validity of the proprietary rights of
others. Any litigation or administrative proceedings will likely result in
substantial expense to the Company and significant diversion of effort by the
Company's technical and management personnel. The prosecution and defense of
intellectual property rights, as with any lawsuit, are inherently uncertain and
carry no guarantee of success. The protection of intellectual property in
certain foreign countries is particularly uncertain. An adverse determination in
litigation or administrative proceedings to which the Company may become a party
could subject the Company to significant liabilities to third parties, require
the Company to seek licenses from third parties, prevent the Company from
selling its products or require the Company to modify its products. Although
patent and intellectual property disputes regarding medical devices are often
settled through licensing and similar arrangements, costs associated with such
arrangements may be substantial and could include ongoing royalties.
Furthermore, there can be no assurance that any necessary licenses would be
available to the Company on satisfactory terms, if at all. Adverse
determinations in a judicial or administrative proceeding or failure to obtain
necessary licenses could prevent the Company from manufacturing and selling its
products, and such events would have a material adverse effect on the Company's
business, financial condition and results of operations. See
"Business -- Trademarks, Trade Secrets and Patent Licenses."
 
     Risks of Regulatory Action. The Company's products and manufacturing
facilities are subject to stringent regulation by the FDA and by various
governmental agencies for the states and localities in which the Company's
products are manufactured and/or sold, as well as by governmental agencies in
certain foreign countries in which the Company's products are manufactured
and/or sold. Pursuant to the FDC Act, and the regulations promulgated
thereunder, the FDA regulates the preclinical and clinical testing, manufacture,
labeling, distribution, sale, marketing, advertising and promotion of medical
devices such as contact lenses. The process of obtaining FDA and other required
regulatory clearances or approvals can be lengthy, expensive and uncertain.
Failure to comply with applicable regulatory requirements can result in, among
other things, fines, suspensions or withdrawals of regulatory clearances or
approvals, product recalls, operating restrictions (including suspension of
production and distribution), product seizures and criminal prosecution. In
addition, governmental regulations may be established that could prevent or
delay regulatory clearances or approval of the Company's products. Delays in
receiving necessary United States or foreign regulatory clearances or approvals,
failure to receive clearances or approvals, or the loss of previously received
clearances or approvals could have a material adverse effect on the Company's
business, financial condition and results of operations.
 
     In general, the FDC Act requires that a new medical device be cleared by
the FDA prior to introducing such product to the United States market through
the submission of a Section 510(k) Pre-Market Notification (a "510(k)
notification") or approved by the FDA prior to introducing such product to the
market through the submission of a Pre-Market Approval Application (a "PMA").
The process of obtaining clearance of a 510(k) notification typically takes five
to twelve months without clinical data, or twelve to eighteen months or more if
clinical data are required to be included in the notification, but it may take
longer, and 510(k) clearance may never be obtained. Approval through the PMA
process, which likewise may never be obtained, generally takes at least eighteen
to twenty-four months and can take substantially longer, is more expensive and
requires the submission of extensive preclinical and clinical data and
manufacturing information, among other things. The soft contact lenses currently
marketed by the Company have received FDA clearance through the 510(k) process
or approval through the PMA process. In addition, the Company has made
modifications to its products that the Company believes do not require the
submission of new 510(k) notifications or PMA supplements. There can be no
assurance, however, that the FDA will agree with any of the Company's
determinations not to submit new 510(k) notifications or PMA supplements for
these changes, that the FDA will not require the Company to cease sales and
distribution while seeking clearances of 510(k)
 
                                       15
<PAGE>   17
 
notifications and approvals of PMA supplements for the changes, or that such
clearances and approvals, if required, will be obtained in a timely manner or at
all. In addition, there can be no assurance that any future products developed
by the Company or any modifications to current products will not require
additional clearances or approvals from the FDA, or that such approvals, if
necessary, will be obtained in a timely manner or at all.
 
     The Company's manufacturing facilities are subject to periodic GMP and
other inspections by the FDA. In March 1996, the Company received a warning
letter from the FDA regarding certain procedures used in manufacturing products
at its facilities in Puerto Rico. The Company has taken steps to address the
FDA's concerns, and, after reinspecting the facilities, the FDA notified the
Company that its concerns were satisfactorily addressed. There can be no
assurance that the Company will be found in compliance with GMP requirements in
future inspections by regulatory authorities, and noncompliance with GMP
requirements could result in the cessation or reduction of the Company's
production volume, which would have a material adverse effect on the Company's
business, financial condition and results of operations.
 
     Sales of medical devices outside the United States are subject to foreign
regulatory requirements that vary widely from country to country. These laws and
regulations range from simple product registration requirements in some
countries to complex clearance and production controls in others. Some countries
have historically permitted human studies earlier in the product development
cycle than regulations in the United States permit. Other countries have
requirements similar to those of the United States. This disparity in the
regulation of medical devices may result in more rapid product clearance in
certain countries than in the United States, while approvals in countries such
as Japan may require longer periods than in the United States. These differences
may also affect the efficiency and timeliness of international market
introduction of the Company's products, and there can be no assurance that the
Company will be able to obtain regulatory approvals or clearances for its
products in foreign countries in a timely manner or at all. See "Business --
Government Regulation."
 
   
     Product Liability; Insurance. The Company has in the past been, and
continues to be, subject to product liability claims and lawsuits, and the
Company's Canadian subsidiary is currently a defendant in one such lawsuit,
filed by an individual in 1997 in the Province of Ontario, Canada, alleging that
the Company's lenses injured the plaintiff's cornea and seeking damages of
Can.$500,000 plus interest and costs. Because contact lenses are medical
devices, the Company faces an inherent risk of exposure to product liability
claims in the event that the use of its products results in personal injury. The
Company also faces the possibility that defects in the design or manufacture of
its products might necessitate a product recall. From time to time, the Company
has received, and may in the future receive, complaints of significant patient
discomfort, including corneal complications, while using the Company's contact
lenses. In certain cases, the reasons for the problems have never been
established. In addition, on two occasions, in 1995 and 1997, the Company has
recalled certain of its products due to labeling errors. Although the Company
has not experienced material losses to date due to product liability claims or
product recalls, there can be no assurance that the Company will not experience
such losses in the future, that insurance coverage will be adequate to cover
such losses, or that insurance coverage will be available on acceptable terms or
at all. A product liability or other judgment against the Company in excess of
the Company's insurance coverage or a product recall could have a material
adverse effect upon the Company's business, financial condition and results of
operations. See "Business -- Product Liability and Insurance."
    
 
     Environmental Regulations. Federal, state and local regulations impose
various controls on the storage, handling, discharge and disposal of certain
substances used in the Company's manufacturing processes and on the Company's
facilities. The Company believes that its activities conform to present
governmental regulations applicable to its current operations and facilities,
including those related to environmental, land use, public utility utilization
and fire code matters. There can be no assurance that such governmental
regulations will not in the future impose the need for additional capital
equipment or other process requirements upon the Company or restrict the
Company's ability to expand its operations. The adoption of such measures or any
failure by the Company to comply with applicable environmental and land use
regulations or to restrict the discharge of hazardous substances could subject
the Company to future liability or could cause its manufacturing operations to
be curtailed or suspended.
 
                                       16
<PAGE>   18
 
     Dependence on Key Personnel. The Company is dependent upon a limited number
of key management and technical personnel. The Company's future success will
depend in part upon its ability to attract and retain highly qualified
personnel. The Company competes for such personnel with other companies,
academic institutions, government entities and other organizations. There can be
no assurance that the Company will be successful in retaining or hiring
qualified personnel. The loss of any of the Company's senior management or other
key research, clinical, regulatory, or sales and marketing personnel,
particularly to competitors, could have a material adverse effect on the
Company's business, financial condition and results of operations. In
particular, the loss of John D. Fruth, the Company's founder and President,
could have a material adverse effect on the Company. See "Business -- Employees"
and "Management."
 
     Control by Existing Stockholders. After the offering contemplated hereby,
the directors, officers and principal stockholders of the Company will, in the
aggregate, beneficially own approximately 62.1% of the Company's outstanding
Common Stock (approximately 57.3% if the Underwriters' overallotment option is
exercised in full). As a result, these stockholders, acting together, will
possess voting control of the Company, giving them the ability, among other
things, to elect the Company's Board of Directors and approve significant
corporate transactions. Such control could have the effect of delaying,
deferring or preventing a change in control of the Company. See "Principal and
Selling Stockholders."
 
     Certain Anti-Takeover Provisions. Upon completion of this offering, the
Company's Board of Directors will have the authority to issue up to 4,000,000
shares of Preferred Stock and to determine the price, rights, preferences,
privileges and restrictions, including voting rights, of those shares without
any further vote or action by the stockholders. The rights of the holders of
Common Stock will be subject to, and may be adversely affected by, the rights of
the holders of any Preferred Stock that may be issued in the future. The
issuance of Preferred Stock, while providing flexibility in connection with
possible financings or acquisitions or other corporate purposes, could have the
effect of making it more difficult for a third party to acquire a majority of
the outstanding voting stock of the Company. The Company has no current plans to
issue shares of Preferred Stock. The Company's Bylaws and indemnity agreements
provide that the Company will indemnify officers and directors against losses
they may incur in legal proceedings resulting from their service to the Company.
Further, the Company's charter documents contain a provision eliminating the
ability of the Company's stockholders to take action by written consent
effective upon the closing of this offering. This provision is designed to
reduce the vulnerability of the Company to an unsolicited acquisition proposal
and to render the use of stockholder written consents unavailable as a tactic in
a proxy fight. However, such provision could have the effect of discouraging
others from making tender offers for the Company's shares, thereby inhibiting
increases in the market price of the Company's shares that could result from
actual or rumored takeover attempts. Such provision also may have the effect of
preventing changes in the management of the Company. In addition, Section 203 of
the Delaware General Corporation Law, to which the Company is subject, restricts
certain business combinations with any "interested stockholder" as defined by
such statute. The statute may delay, defer or prevent a change in control of the
Company. See "Description of Capital Stock."
 
     Shares Eligible for Future Sale; Registration Rights. Sales of a
substantial number of shares of Common Stock in the public market following this
offering could adversely affect the market price for the Company's Common Stock.
The number of shares of Common Stock available for sale in the public market is
limited by restrictions under the Securities Act of 1933, as amended (the
"Securities Act") and by lock-up agreements under which the holders of such
shares have agreed not to sell or otherwise dispose of any of their shares for a
period of 180 days after the date of this Prospectus without the prior written
consent of Morgan Stanley & Co. Incorporated. However, Morgan Stanley & Co.
Incorporated may, in its sole discretion and at any time without notice, release
all or any portion of the securities subject to lock-up agreements. In the
absence of any early release from lock-up agreements by Morgan Stanley & Co.
Incorporated, substantially all of the outstanding shares of Common Stock other
than the 7,200,000 shares offered hereby will become eligible for sale 180 days
after the date of this Prospectus. In addition, the Company intends to register
on or promptly after the effective date of this offering a total of 5,658,988
shares of Common Stock reserved for issuance under the Company's stock option
plans. Further, upon expiration of the lock-up agreements referred to above,
holders of approximately 12,323,120 shares of Common Stock will be entitled to
certain registration rights
 
                                       17
<PAGE>   19
 
with respect to such shares. If such holders, by exercising their registration
rights, cause a large number of shares to be registered and sold in the public
market, such sales could have a material adverse effect on the market price for
the Company's Common Stock, and could adversely affect the Company's ability to
raise capital. See "Description of Capital Stock -- Registration Rights" and
"Shares Eligible for Future Sale."
 
     No Prior Trading Market; Possible Volatility of Stock Price. Prior to this
offering, there has been no public market for the Common Stock of the Company,
and there can be no assurance that an active trading market will develop or
that, if one does develop, it will be maintained. The initial public offering
price, which will be established by negotiations between the Company, the
Selling Stockholders and the representatives of the Underwriters based upon a
number of factors, may not be indicative of prices that will prevail in the
trading market. See "Underwriters" for a discussion of the factors to be
considered in determining the initial public offering price. The market price of
the shares of Common Stock is likely to be highly volatile and may be
significantly affected by factors such as actual or anticipated fluctuations in
the Company's operating results or those of its competitors, competitive
factors, new products offered by the Company or its competitors, developments
with respect to patents or proprietary rights, conditions and trends in its
industry and other related industries, regulatory actions, adoption of new
accounting standards, changes in financial estimates by securities analysts,
general market conditions and other factors. In addition, the stock market has
from time to time experienced significant price and volume fluctuations that may
adversely affect the market price of the Company's Common Stock. In the past,
following periods of volatility in the market price of a particular company's
securities, securities class action litigation has often been brought against
that company. Such litigation, if brought against the Company, could result in
substantial costs and a diversion of management's attention and resources. See
"Underwriters."
 
     Immediate and Substantial Dilution. Investors participating in this
offering will incur immediate, substantial dilution in the amount of $12.37. To
the extent that options to purchase the Company's Common Stock are exercised,
there will be further dilution. See "Dilution."

                                USE OF PROCEEDS
 
     The net proceeds to the Company from the sale of the 3,600,000 shares of
Common Stock offered by the Company hereby are estimated to be approximately
$52.5 million, at an assumed initial public offering price of $16.00 per share
and after deducting estimated underwriting discounts and commissions and
estimated offering expenses payable by the Company. The Company will not receive
any of the proceeds from the sale of Common Stock by the Selling Stockholders.
See "Principal and Selling Stockholders."
 
     The Company intends to use approximately $22.0 million of the net proceeds
of this offering for expansion and automation of its manufacturing facilities.
See "Risk Factors -- Manufacturing Capacity Constraints; Risks Associated with
Expansion and Automation of Manufacturing Operations." In addition, the Company
expects to use approximately $13.5 million of the net proceeds to repay all of
the debt outstanding under the Company's Credit Agreement with Comerica
Bank-California (the "Comerica Credit Agreement") and $2.9 million to repay
subordinated debt owed to John D. Fruth, the Company's President. As of June 30,
1997, the effective interest rate on the indebtedness under the Comerica Credit
Agreement was approximately 8.2% per annum. The amount outstanding under the
Comerica Credit Agreement was incurred on October 30, 1996 and utilized to repay
previously outstanding indebtedness. The debt owed to John D. Fruth was borrowed
from July 1986 to March 1990 to meet certain short-term operating cash
requirements, and bears interest at the prime rate plus 3%. This debt is due
upon the earlier of the consummation of this offering and November 1997. See
"Certain Transactions -- Loans from Mr. Fruth." The Company is also obligated,
upon the closing of this offering, to pay the remaining $6.7 million owed
pursuant to the settlement agreement in certain recent litigation in the United
Kingdom and California. See "Certain Transactions -- OSL Acquisition and Related
Litigation." The Company intends to use the remaining net proceeds of
approximately $7.4 million for other general corporate purposes, including
working capital. Pending such uses, the net proceeds of this offering will be
invested in short-term, interest-bearing, investment grade securities. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources."
 
                                DIVIDEND POLICY
 
     The Company has never declared or paid any cash dividends on its Common
Stock, and the payment of cash dividends on its Common Stock is prohibited under
the Comerica Credit Agreement. Since January 31, 1993, the Company has paid
cumulative dividends quarterly on its Preferred Stock at the rate of $0.6975 per
share per annum. Upon the closing of this offering, all outstanding shares of
Preferred Stock will be converted into shares of Common Stock. The Company
currently expects to retain all future earnings for use in the operation and
expansion of its business and does not anticipate paying any cash dividends on
its capital stock in the foreseeable future.

                                    DILUTION
 
     The pro forma net tangible book value of the Company as of June 30, 1997
was approximately $21.7 million or $1.29 per share of Common Stock. "Pro forma
net tangible book value" per share represents the amount of total tangible
assets less total liabilities, divided by the number of shares of Common Stock
then outstanding (giving pro forma effect to the conversion of all
then-outstanding shares of Preferred Stock into shares of Common Stock). After
giving effect to the sale by the Company of the 3,600,000 shares of Common Stock
offered by the Company hereby (at an assumed initial public offering price of
$16.00 per share and after deducting estimated underwriting discounts and
commissions and estimated offering expenses payable by the Company), the
Company's pro forma net tangible book value as of June 30, 1997 would have been
approximately $74.1 million, or $3.63 per share of Common Stock. This represents
an immediate increase in pro forma net tangible book value of $2.34 per share to
existing stockholders and an immediate dilution of $12.37 per share to new
investors purchasing shares of Common Stock in this offering. The following
table illustrates this per share dilution:

(1) Sales by the Selling Stockholders in this offering will reduce the number of
    shares of Common Stock held by existing stockholders to 13,226,326, or
    approximately 64.8% of the total shares of Common Stock outstanding
    immediately after this offering, and will increase the number of shares of
    Common Stock held by new investors to 7,200,000, or 35.2% of the total
    number of shares of Common Stock outstanding immediately after this

     The foregoing computations assume no exercise of stock options outstanding
as of June 30, 1997. As of June 30, 1997, there were options outstanding to
purchase a total of 3,079,694 shares of Common Stock at a weighted average
exercise price of $1.76 per share. To the extent that any of these options are
exercised, there will be further dilution to new public investors. See

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The following discussion should be read in conjunction with the
Consolidated Financial Statements and Notes thereto included elsewhere in this
Prospectus. The following discussion contains forward-looking statements. The
Company's actual results may differ significantly from those projected in the
forward-looking statements. Factors that might cause future actual results to
differ materially from the Company's recent results or those projected in the
forward-looking statements include, but are not limited to, those discussed in
"Risk Factors" and below. The Company assumes no obligation to update the
forward-looking statements or such factors.
 
OVERVIEW
 
     The Company's products compete in both the disposable and annual
replacement segments of the soft contact lens market. Since the Company was
incorporated in 1985, its strategy has been to market high-quality contact
lenses to eyecare practitioners at competitive prices using a low cost-to-serve
operating structure. Until 1992, the Company was principally a distributor of
contact lenses. In September 1992, the Company became an integrated contact lens
company by acquiring the primary supplier of its lenses, Precision Lens
Laboratories Ltd. ("PLL"), a United Kingdom-based company now called Ocular
Sciences Ltd. ("OSL"). In connection with the acquisition, PLL entered into a
royalty-bearing patent license with certain of the prior owners of PLL related
to the cast molding of contact lenses and agreed to supply lenses to Aspect
Vision Care Ltd. ("AVCL"), a United Kingdom-based contact lens distributor
controlled by certain of such owners. This license provided the Company with the
technology to manufacture high-quality contact lenses at significantly lower per
unit production costs than it could previously achieve. In connection with these
agreements, PLL agreed not to sell certain contact lenses covered by these
agreements to third parties in the United Kingdom and to pay an additional
royalty for certain sales to contact lens manufacturers, and AVCL agreed not to
sell such lenses in North and South America. See "Certain Transactions -- OSL
Acquisition and Related Litigation."
 
     In October 1992, the Company acquired the contact lens business in North
and South America of Allergan, Inc., which had been operating under the name
American Hydron. This acquisition provided the Company with a significantly
expanded customer base, an additional line of contact lens products and a
manufacturing facility in Puerto Rico. The purchase price was $24.5 million,
including acquisition costs of $1.2 million. The transaction and working capital
requirements were financed by the issuance of $5.0 million in Common Stock, $1.0
million in Preferred Stock and $22.7 million in senior secured and senior
subordinated notes and warrants to purchase common stock to the seller and a
separate investor group. The senior secured notes were repaid from bank
borrowings in 1993 and the senior subordinated notes were repaid with borrowings
under the Comerica Credit Agreement, which the Company entered into in October
1996. The Company intends to repay all of the outstanding borrowings under the
Comerica Credit Agreement ($13.5 million as of June 30, 1997) with a portion of
the net proceeds of this offering. See "Use of Proceeds." The American Hydron
acquisition resulted in goodwill and other intangible assets of $3.4 million,
all of which will be fully amortized by the end of 1997. See "Certain
Transactions -- Allergan/American Hydron Acquisition; Galen Financing."
 
     Prior to the summer of 1993, the Company derived a substantial majority of
its sales from lenses for annual replacement regimens and the remainder of its
sales from lenses for monthly disposable replacement regimens. In the third
quarter of 1993, the Company began selling lenses for weekly disposable
replacement regimens. Since that time, substantially all of the Company's growth
in net sales has resulted from sales of lenses for disposable replacement
regimens, primarily weekly disposable replacement regimens. In the first quarter
of 1995, the Company introduced a second line of lenses for weekly disposable
replacement regimens. The Company's lenses for disposable replacement regimens
historically have had lower selling prices and gross margins and are sold in
much greater volumes than its lenses for annual replacement regimens. In the
first six months of 1997, lenses for disposable replacement regimens accounted
for approximately 88.3% of the Company's unit volume and 73.8% of net sales. See
"Risk Factors -- Dependence on Single Product Line; Need to Increase Sales of
Lenses for Disposable Replacement Regimens." The Company's international sales
 
                                       23
<PAGE>   25
 
represented 18.1% and 20.5% of the Company's net sales in 1996 and the six
months ended June 30, 1997, respectively, and are growing somewhat faster than
domestic sales as the Company establishes partnering and distributor
relationships abroad. See "Risk Factors -- Risks Relating to International
Operations; Need to Increase Sales in International Markets." In 1996,
approximately 54% of the Company's U.S. net sales came from sales to
ophthalmologists, optometrists and the distributors that sell to such
practitioners, and approximately 46% of the Company's U.S. net sales came from
sales to chain stores and mass merchants.
 
     In May 1994, the Company and OSL commenced a litigation in the United
Kingdom against certain of the persons who sold OSL to the Company, including
Geoffrey and Anthony Galley, AVCL and certain related parties, for actions taken
after the acquisition. Certain of the defendants in that action brought suit
against OSL in a related patent infringement action. The Company also brought an
action in the United States against certain of the individuals that it had sued
in the United Kingdom (these suits, collectively, the "U.K. Litigation"). In
February 1997, the Company entered into a settlement agreement providing for,
among other things, (i) a mutual release and termination of all pending
litigation, (ii) the replacement of the previous patent license with a new,
fully paid, non-exclusive patent license that does not contain any restrictions
on the Company's ability to sell lenses to other contact lens manufacturers,
(iii) the grant by OSL to AVCL and the patent owners of a royalty-free,
non-exclusive license to certain OSL technology, (iv) the termination of OSL's
obligation to supply contact lenses to AVCL and (v) the elimination of the
geographic limitation on OSL's and AVCL's ability to sell certain contact
lenses. In connection with the settlement, the Company paid $3.3 million to the
defendants and agreed to pay an additional $6.7 million upon the earlier of
February 27, 1998 or the sale of the Company's Common Stock in an initial public
offering. The Company has allocated $8.8 million of the total consideration paid
to the defendants to identifiable intangible assets as of the date of the
settlement based on their relative fair market values. See Note 14 of Notes to
Consolidated Financial Statements. The Company plans to amortize these
intangible assets amount over a ten-year period. In connection with the U.K.
Litigation, the Company incurred legal expenses of $549,000, $1.3 million and
$2.5 million in 1994, 1995 and 1996 and $649,000 and $52,000 for the six months
ended June 30, 1996 and 1997, respectively, which are included in the Company's
general and administrative expenses. See "Certain Transactions -- OSL
Acquisition and Related Litigation."

     Net Sales. Net sales represents gross sales less volume discounts, trial
set discounts, prompt payment discounts and allowances for sales returns. The
Company recognizes sales upon shipment of products to its customers. Discounts
and allowances for sales returns are accrued at the time sales are recognized.
Net sales increased 36.3% to $53.0 million in the six months ended June 30, 1997
from $38.9 million in the six months
    
 
                                       24
<PAGE>   26
 
ended June 30, 1996. Substantially all of this growth resulted from increased
sales of the Company's lenses marketed for weekly disposable replacement
regimens. Unit sales of the Company's lenses for annual replacement regimens
remained virtually constant between the comparison periods. The prices of each
of the Company's primary products did not decrease significantly between the
comparison periods. However, as a result of a shift in product mix from lenses
marketed for annual replacement to lower priced lenses marketed for disposable
replacement, the Company's overall average selling price declined approximately
11%. The Company expects that the overall average selling price that it realizes
across its products will decline over time because of (i) shifts in the
Company's product mix from lenses for annual replacement regimens to lenses for
disposable replacement regimens and, within its disposable lenses, to lenses
that are replaced more frequently, (ii) decreases in the prices of lenses for
disposable replacement regimens and (iii) increases in products sold
internationally through distributors at prices lower than direct sales prices in
the United States. The Company does not expect there to be significant growth in
its sales of lenses for annual replacement. The Company does not believe that
its net sales growth rate from the six months ended June 30, 1996 to the six
months ended June 30, 1997 is indicative of the Company's long-term sales growth
rate.
 
     Gross Profit. Cost of sales is comprised primarily of the overhead,
material and labor costs of production and packaging, freight and duty,
inventory reserves, royalties to third parties and amortization of certain
intangible assets. A substantial portion of the Company's cost of sales is fixed
and therefore declines as a percentage of net sales as volume increases. Gross
profit increased 42.0% to $32.5 million, or 61.4% of net sales, in the six
months ended June 30, 1997 from $22.9 million, or 59.0% of net sales, in the six
months ended June 30, 1996. The Company's per unit production cost reductions
resulting from manufacturing volume increases and process improvements were
slightly greater than the Company's overall average selling price decline,
resulting in improved margins. The Company anticipates that its overall average
selling price will decline over time and anticipates higher depreciation as a
result of significantly increased investment in property and equipment, which
will increase its cost of sales. Accordingly the Company will need to continue
to reduce its per unit production costs through increased automation, increased
volume and reduced packaging costs in order to improve, or even to maintain, its
gross margins. See "Risk Factors -- Manufacturing Capacity Constraints; Risks
Associated With Expansion and Automation of Manufacturing Operations."
 
     Selling and Marketing Expenses. Selling and marketing expenses are
comprised primarily of cooperative merchandising allowances, salaries,
commissions and benefits for selling and marketing personnel, sample diagnostic
products provided to eyecare practitioners without charge and postage and
freight charges not billed to customers. Cooperative merchandising allowances
are reimbursements made principally to chain stores and mass merchants for items
such as advertising, displays and mailings that are intended to encourage the
fitting and wearing of the Company's lenses for disposable replacement regimens.
These allowances are limited to a percentage of purchases of lenses for
disposable replacement regimens from the Company. Selling and marketing expenses
increased 45.3% to $12.0 million, or 22.6% of net sales, in the six months ended
June 30, 1997 from $8.2 million, or 21.2% of net sales, in the six months ended
June 30, 1996. Nearly half of the dollar increase and substantially all of the
increase in the percentage of net sales resulted from increases in cooperative
merchandising allowances. An additional portion of the dollar increase came from
increased selling and marketing expenses in the United Kingdom and Canada and
increased shipments of diagnostic lenses to eyecare practitioners without
charge. The Company expects that it will continue to increase cooperative
merchandising allowances as a percentage of net sales in order to seek further
market share increases and, as a result, that selling and marketing expenses
will increase as a percentage of net sales.
 
   
     General and Administrative Expenses. General and administrative expenses
are comprised primarily of salaries and benefits for distribution personnel,
general and administrative personnel, research and development personnel,
professional services, consultants' fees and non-manufacturing facilities costs.
General and administrative expenses increased 14.3% to $10.1 million in the six
months ended June 30, 1997 from $8.8 million in the six months ended June 30,
1996, but declined as a percentage of net sales from 22.7% to 19.0%. The
majority of the dollar increase came from sales and use tax provisions, higher
salaries and benefits to employees, fees to regulatory consultants and increased
depreciation. Substantially all of the decrease in the percentage of net sales
came from reductions in professional fees, partially as a result of the
settlement of the U.K. Litigation in February 1997. The Company believes that
its general and administrative expenses will
    
 
                                       25
<PAGE>   27
 
increase as a result of expenses associated with being a public company and
amortization of intangible assets acquired in connection with the settlement of
the U.K. Litigation.
 
     Interest and Other Expense, Net. Interest and other expense, net decreased
36.5% to $845,000, or 1.6% of net sales, in the six months ended June 30, 1997,
from $1.3 million, or 3.4% of net sales, in the three months ended March 31,
1996. This decrease primarily resulted from a reduction in the aggregate amount
of the Company's borrowings.
 
     Income Taxes. Income taxes were $2.9 million in the six months ended June
30, 1997 and $1.3 million in the six months ended June 30, 1996 and income taxes
as a percentage of income before taxes increased to 30.0% in the six months
ended June 30, 1997 from 28.2% in the six months ended June 30, 1996. The
absolute level of the Company's effective tax rate is affected favorably by
earnings attributable to the Company's Puerto Rican operations, which are
partially exempt from United States income taxation. The Company anticipates
that it will continue to benefit from this favorable effect through 2001, when
the benefit of this exemption will expire for the Company under the current
provisions of the statute. Pending federal legislation would, if adopted, extend
this exemption beyond 2001 or replace it with other tax benefits after that
year. In addition, the Company's planned installation of highly automated
production lines in Puerto Rico could cause an increase in the Company's tax
rate if the automation results in a significant reduction in the Company's labor
costs in Puerto Rico in relation to its Puerto Rican earnings. See Note 11 of
Notes to Consolidated Financial Statements.
 
     Year Ended December 31, 1996 Compared to Year Ended December 31, 1995
 
     Net Sales. Net sales increased 32.9% to $90.5 million in 1996 from $68.1
million in 1995. Substantially all of this growth resulted from increased sales
of the Company's weekly disposable lens products. The overall average price of
the Company's lenses for weekly disposable replacement regimens was similar in
1995 and 1996. The Company's sales of lenses for annual replacement regimens
declined slightly in both volume and average price from 1995 to 1996.
 
     Gross Profit. Gross profit increased 30.8% to $54.0 million in 1996 from
$41.3 million in 1995, but gross margin decreased to 59.6% in 1996 from 60.6% in
1995. Gross margin declined primarily as a result of a faster decrease in
overall average selling price than decreases in unit cost of sales. The
reduction in overall average selling price of 13.2% was caused by an increased
percentage of lenses for disposable replacement regimens, which have lower
prices, and an increased percentage of lower-priced international distributor
sales in the Company's product mix. Implementation of certain manufacturing
process improvements was delayed by an unrelated postponement by the FDA of its
GMP inspection of the Company's new United Kingdom facility, and this delay
prevented the reduction in cost of sales from completely offsetting the
reduction in average selling price as planned. Additionally, the Company
recorded provisions in 1996 totalling approximately $500,000 related to start-up
and scrap costs in connection with the transition from vial to blister packaging
of the Company's lenses for disposable replacement regimens.
 
     Selling and Marketing Expenses. Selling and marketing expenses increased
54.3% to $18.1 million in 1996 from $11.7 million in 1995, while increasing to
20.0% of net sales in 1996 from 17.2% of net sales in 1995. A combination of
increased expenditures for cooperative merchandising allowances and, to a lesser
extent, for Company-paid freight caused both by an increase in volume and by the
need to fulfill product backorders rapidly and for shipments of diagnostic
lenses to eyecare practitioners without charge accounted for $4.6 million of the
year-to-year increase. Both the shipment of free diagnostic lenses and the
payment of cooperative merchandising allowances were factors related to the
Company's sales of disposable lenses, which grew at rates in excess of the
Company's overall net sales volume. The increase in cooperative merchandising
allowances accounted for substantially all of the increase in selling and
marketing expenses as a percentage of net sales, with increases in advertising
and promotion accounting for the remainder.
 
     General and Administrative Expenses. General and administrative expenses
increased 28.9% to $18.4 million in 1996 from $14.3 million in 1995, but
decreased as a percentage of net sales to 20.3% from 21.0%. Legal expenses
related to the U.K. Litigation and the expense of the associated settlement
accounted for $1.2 million of the year-to-year dollar increase in general and
administrative expenses. Most of the
 
                                       26
<PAGE>   28
 
remaining increase resulted from increases in building and utilities expenses,
salaries and benefits for general and administrative personnel and professional
fees. Excluding expenses of the U.K. Litigation, general and administrative
expenses would have decreased to 17.6% of net sales in 1996 from 19.0% of net
sales in 1995. This decrease was the result of limited growth in distribution
expenses relative to the growth in net sales and absolute declines in the dollar
amounts of amortization of goodwill and other intangibles and of research and
development expenses.
 
     Income From Operations. Income from operations increased 14.3% to $17.4
million in 1996 from $15.3 million in 1995 but decreased to 19.3% of net sales
in 1996 from 22.4% of net sales in 1995. Excluding expenses of the U.K.
Litigation, income from operations in 1996 would have been 22.0% of net sales,
as compared to 24.3% of net sales in 1995.
 
     Interest and Other Expense, Net. Interest and other expense, net increased
to $3.3 million in 1996 from $2.6 million in 1995 as a result of an increase in
interest expense, a decrease in interest income and a decrease in other income.
 
     Income Taxes. Income taxes were $4.0 million in 1996 and $3.9 million in
1995. Income taxes declined as a percentage of income before taxes to 28.2% in
1996 from 30.6% in 1995. This reduction in the Company's effective income tax
rate resulted from an increase in earnings attributable to the Company's Puerto
Rican operations, which are partially exempt from United States income taxation.
 
     Net Income. Net income increased 15.8% to $10.2 million in 1996 from $8.8
million in 1995. Excluding expenses of the U.K. Litigation, net income would
have increased $2.3 million or 23.5% from 1995 to 1996.
 
     Year Ended December 31, 1995 Compared to Year Ended December 31, 1994
 
     Net Sales. Net sales increased 40.4% to $68.1 million in 1995 from $48.5
million in 1994. This growth in net sales resulted primarily from introduction
of the Company's 55% water lens for weekly disposable replacement regimens in
the first quarter of 1995 and continued increases in unit sales of the Company's
38% water lens for weekly disposable replacement regimens and, to a
significantly lesser extent, unit sales of the Company's daily-wear annual
replacement lenses.
 
     Gross Profit. Gross profit increased to $41.3 million in 1995 from $26.0
million in 1994, while gross margin increased to 60.6% in 1995 from 53.5% in
1994. Gross margin improved because of per unit production cost declines
resulting from manufacturing volume increases and process improvements. These
per unit production cost declines more than offset a significant reduction in
overall average selling price caused by the increased percentage of lower-priced
disposable products in the Company's product mix. The Company incurred no
significant start-up costs from the launch of its second weekly disposable lens
product, and maintained historical product return and sales allowance rates as
well as provisions for excess and obsolete inventory.
 
     Selling and Marketing Expenses. Selling and marketing expenses increased
83.1% to $11.7 million in 1995 from $6.4 million in 1994, while increasing to
17.2% of net sales in 1995 from 13.2% of net sales in 1994. A combination of
increased staffing levels in the United States, shipment of diagnostic lenses to
eyecare practitioners without charge, cooperative merchandising allowances and
company-paid freight caused largely by fulfillment of product backorders
accounted for $4.3 million of the year-to-year dollar increase and a substantial
majority of the increase in percentage of net sales. Both the shipment of free
diagnostic lenses and the payment of cooperative merchandising allowances were
factors related to the Company's sales of disposable lenses, which grew more
rapidly than the Company's overall net sales volume.
 
     General and Administrative Expenses. General and administrative expenses
increased 28.9% to $14.3 million in 1995 from $11.1 million in 1994 but
decreased to 21.0% of net sales in 1995 from 22.9% of net sales in 1994.
Increased staffing levels in the Company's distribution center and finance
department, together with increases in depreciation and amortization related to
increased capital expenditures, accounted for $1.8 million of the increase.
Legal fees for the U.K. Litigation accounted for $771,000 of the year-to-year
increase. Excluding expenses of the U.K. Litigation, general and administrative
expenses declined from 21.7% of net sales in 1994 to 19.0% of net sales in 1995.
 
                                       27
<PAGE>   29
 
     Income From Operations. Income from operations increased 80.3% to $15.3
million in 1995 from $8.5 million in 1994, while increasing to 22.4% of net
sales in 1995 from 17.4% of net sales in 1994. Excluding expenses of the U.K.
Litigation, income from operations would have increased to 24.3% of net sales in
1995 from 18.6% of net sales in 1994.
 
     Interest and Other Expense, Net. Interest and other expense, net decreased
to $2.6 million in 1995 from $3.4 million in 1994 as a result of lower
borrowings under the Company's credit facility, increased interest income on
higher cash and cash equivalent balances and increased other income.
 
     Income Taxes. Income taxes in 1995 were $3.9 million or 30.6% of income
before taxes. In 1994, the Company did not record a tax provision because of
operating loss carryforwards from prior years. Those losses were fully utilized
in 1994. The effective tax rate for 1995 was below the combined federal and
state statutory rates, principally as a result of earnings attributable to the
Company's Puerto Rican operations, which are partially exempt from U.S. income
taxation.
 
     Net Income. Net income increased 74.5% to $8.8 million in 1995 from $5.0
million in 1994. Excluding expenses of the U.K. Litigation, net income would
have increased 73.8% to $9.7 million in 1995 from $5.6 million in 1994.

     The Company's quarterly operating results have varied in the past and are
likely to vary in the future significantly based upon a number of factors. The
Company's historical sales have exhibited significant seasonality, with the
third and fourth quarters having the highest net sales in any year and the first
quarter of the following year having lower net sales than the preceding two
quarters. The Company believes that the seasonality of its quarterly results is
primarily due to consumer buying habits. The Company believes that the
historical increase in sales of its products in the third and fourth quarters
have been due to late summer (back-to-school) purchases by consumers and to
higher traffic in the fourth quarter through malls and mass merchandisers with
optical outlets. The Company further believes that the historical decline in the
first quarter has been due to reduced consumer buying in the post-holiday
season. In addition, due to the relatively high proportion of the Company's
fixed costs to its total costs, the Company's level of profitability has
historically increased significantly with increasing sales volumes, resulting in
disproportionately better results in the second half of each year. There can be
no assurance that these patterns will not continue in future years, although the
pattern may be somewhat less pronounced if the Company continues to increase the
proportion of sales represented by more frequently replaced lenses for
disposable replacement regimens. See "Risk Factors -- Fluctuations In Operating
Results; Seasonality; Decreasing Average Sales Prices."
 
RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS
 
     SFAS No. 123, "Accounting for Stock-Based Compensation," encourages, but
does not require, a fair market value-based method of accounting for employee
stock options or similar equity instruments. The Company has elected to continue
to measure compensation cost under Accounting Principles Board Opinion No. 25,
"Accounting for Stock Issued to Employees," as was previously required, and to
comply with pro forma disclosure of net income and earnings per share as if the
fair market value-based method of accounting had been applied.
 
     In February 1997, the Financial Accounting Standards Board issued SFAS No.
128, "Earnings Per Share." SFAS 128 supersedes APB Opinion No. 15, "Earnings Per
Share," and specifies the computation, presentation, and disclosure requirements
for earnings per share ("EPS") for entities with publicly held common stock or
potential common stock. It replaces the presentation of primary EPS with a
presentation of basic EPS and replaces the presentation of fully diluted EPS
with a presentation of diluted EPS. It also requires dual presentation of basic
and diluted EPS on the face of the income statement for all entities with
complex capital structures and requires a reconciliation of the numerator and
denominator of the basic EPS computation to the numerator and denominator of the
diluted EPS computation. The Company will adopt SFAS 128 for its interim and
annual consolidated financial statements that end after December 15, 1997 and
will restate all prior period earnings per share data. The Company expects that
its basic earnings per share will be greater than primary earnings per share and
diluted earnings per share will be substantially similar to the pro forma net
income per share disclosed in the consolidated financial statements included
elsewhere in this Prospectus.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     From January 1, 1994 to June 30, 1997, the Company's cash flows from
operating activities have been sufficient to fund substantially all of the
Company's cash requirements. Over this period, the Company generated cash-based
earnings (net income plus depreciation and amortization) of $43.9 million, which
were utilized to make purchases of property, plant and equipment of $34.0
million and to effect net repayments of long-term debt of $5.0 million. A
provision has been made for income taxes on unremitted earnings of subsidiaries
except in cases in which earnings of foreign subsidiaries are deemed to be
invested indefinitely. Such earnings would become taxable and payable upon the
sale or liquidation of these subsidiaries or upon remittance of dividends.
Although it is not practical to estimate the amount of additional tax that might
be payable upon such events, credits for foreign income taxes paid will be
available, at tax rates substantially equal to any resulting U.S. tax liability.
Net cash provided by operating activities was $10.0 million in 1994, $9.5
million in 1995, $12.7 million in 1996 and $10.7 million in the first six months
of 1997.
 
     Working capital increased from $11.9 million at December 31, 1995 to $15.1
million at December 31, 1996 and then decreased to $4.0 million at June 30,
1997. The increase from 1995 to 1996 was primarily
 
                                       29
<PAGE>   31
 
caused by an increase in accounts receivable offset in part by an increase in
accrued liabilities. The decrease from 1996 to 1997 was primarily the result of
an increase in accrued liabilities associated with the settlement of the U.K.
Litigation. At June 30, 1997, the Company had a cash and cash equivalents
balance of $4.0 million and restricted cash of $455,000 held in escrow for the
rent of the Company's United Kingdom facility.
 
     In 1994, 1995, 1996 and the first six months of 1997, net cash provided by
operating activities was derived principally from net income of $5.0 million,
$8.8 million, $10.2 million and $6.8 million, respectively, adjusted for
depreciation and amortization of $2.1 million, $2.6 million, $4.9 million and
$3.5 million, respectively, offset by changes in operating assets and
liabilities.
 
     Net cash used in investing activities in 1994, 1995, 1996 and the first six
months of 1997 was $2.1 million, $15.9 million, $11.5 million and $8.1 million.
In 1994, 1995 and 1996, substantially all of this net cash was used to purchase
property and equipment. In the first six months of 1997, the Company used $3.3
million to purchase intangible assets as part of the settlement of the U.K.
Litigation and $6.0 million to purchase property and equipment. Net cash used in
financing activities in 1994, 1995, 1996 and the first six months of 1997 was
$2.0 million, $217,000, $316,000 and $2.4 million. In each of these periods, net
cash was used primarily for net repayments of long-term debt.
 
     Under the Comerica Credit Agreement, as of June 30, 1997, the Company had
outstanding $8.0 million principal amount of loans under a term loan facility
and $5.5 million principal amount of loans under a revolving line of credit
facility, all of which bore interest as of such date at a rate of approximately
8.2% per annum. The Company will utilize a portion of the net proceeds from this
offering to repay these loans in full. See "Use of Proceeds" and Note 6 of Notes
to Consolidated Financial Statements. Effective upon the closing of this
offering, the Company intends to amend the Comerica Credit Agreement and has
received a commitment from Comerica Bank-California for an amended and restated
credit agreement (the "Amended Credit Agreement") under which the Company could
borrow up to $20 million in revolving credit loans. Outstanding borrowings under
the Amended Credit Agreement are expected to fluctuate based on investment
levels in working capital and property and equipment. The Company expects that
the Amended Credit Agreement will terminate on June 30, 2000, and will be
secured by a pledge of stock of the Company's subsidiaries. Following the
closing of this offering, borrowings under the Amended Credit Agreement would
bear interest at Comerica's prime rate or at Comerica's Eurodollar rate plus a
specified margin that varies based on the Company's ratio of debt to tangible
net worth. The Company's Puerto Rican subsidiary also has a credit facility with
Banco Bilbao de Vizcaya, Puerto Rico ("BBV"), under which it may borrow up to
$5.8 million for the construction and development of a new manufacturing
facility in Puerto Rico and the purchase of new equipment. This loan is
guaranteed by the Company, matures in December 1997 and is secured by the
machinery and equipment purchased with the loan proceeds. As of June 30, 1997,
the Company's Puerto Rican subsidiary had loans with a principal amount of $2.0
million outstanding under this facility. The Company is negotiating with BBV for
an increase in the size and extension of the maturity of this facility. The
Company's Puerto Rican subsidiary has received a commitment from the Government
Development Bank for Puerto Rico (the "GDB") to provide up to $10.0 million of
long-term loans to refinance its borrowings from BBV upon completion of the new
manufacturing facility, and the Company is currently negotiating with the BBV
for a corresponding increase in its commitment. See Note 6 of Notes to
Consolidated Financial Statements. The Company's new financing arrangements with
Comerica Bank -- California and the GDB are subject to definitive documentation
and certain other conditions, and no assurance can be given as whether, or on
what terms, the Company will enter into such arrangements.
 
     The Company is obligated to pay the remaining $6.7 million owed under the
settlement agreement in the U.K. Litigation upon the closing of this offering.
See "Certain Transactions -- OSL Acquisition and Related Litigation." The
Company also intends to use a portion of the net proceeds of this offering to
repay a $2.9 million note to John D. Fruth, the Company's President. In
addition, the Company is obligated to make minimum base payments on
noncancelable operating leases of $2.3 million, $2.2 million and $2.1 million in
1997, 1998 and 1999, respectively. Finally, the Company has existing commitments
to make capital expenditures of $2.9 million and expects to make additional
capital expenditures of $40.6 million through 1998, primarily to add highly
automated production lines at its facility in the United Kingdom and for
equipment and leasehold improvements at its planned new facility in Puerto Rico.

     The Company believes that the net proceeds from this offering, together
with its current cash and cash equivalents, further borrowings available under
its credit facilities and its anticipated net cash flow from operations, will be
sufficient to meet its anticipated cash needs for working capital, contractual
commitments and capital expenditures for at least the next 12 months. If cash
generated from operations proves insufficient to satisfy the Company's liquidity
requirements, the Company may seek to sell additional equity or debt securities
or obtain another credit facility. The sale of additional equity or convertible
debt securities could result in additional dilution to the Company's
stockholders. The sale of additional debt or further bank borrowings could
subject the Company to additional restrictive financial covenants and
restrictions on the payment of dividends. There can be no assurance that
financing will be available to the Company in amounts or on terms acceptable to
the Company, if at all.

                                    BUSINESS
 
     The Company is a rapidly growing manufacturer and marketer of soft contact
lenses. The Company manufactures a broad line of soft contact lenses for annual
and disposable replacement regimens. The Company believes that its lens designs
provide wearers with a higher level of comfort and greater ease of handling than
those of its leading competitors. The Company's manufacturing technologies
permit consistent, cost-effective reproduction of these designs, allowing the
Company to offer its lenses at competitive prices. In addition, the Company has
implemented marketing strategies designed to assist eyecare practitioners, both
in independent practice and in retail chains, in retaining their patients and
monitoring their patients' ocular health, thereby providing a significant
incentive for practitioners to prescribe the Company's lenses. Furthermore, the
Company has continuously focused on lowering its non-manufacturing costs, or
"cost-to-serve," enabling it to increase its profitability and its flexibility
to reduce prices. To minimize its cost-to-serve, the Company utilizes a
telemarketing sales force and directs its marketing efforts toward eyecare
practitioners rather than consumers.
 
     The Company believes that practitioners can increase their patient
retention and provide better ongoing patient care by providing
competitively-priced, high-quality products that are differentiated by brand
from those provided by competing channels. Accordingly, the Company has
successfully implemented a strategy to address the needs of eyecare
practitioners. The Company markets its lenses solely to eyecare practitioners,
both in private practice and in retail optical chains, rather than to consumers.
The Company believes that focusing on the eyecare practitioner, who
significantly influences the selection of the brand of contact lenses worn by
the patient, is critical to its ability to market contact lenses successfully.
The Company does not sell to mail-order companies, pharmacies or other
distribution channels that do not provide the regular eye examinations necessary
to maintain overall ocular health.
 
     Over the last five years, the Company has established itself as a leader in
the spherical, non-specialty annual replacement segment of the United States
market with a market share estimated at 25% in 1996, based on unit sales. Since
its introduction of lenses for weekly disposable replacement regimens in 1993,
the Company has steadily increased its share of this growing market, reaching
approximately 8% of total unit sales in the United States during the second half
of 1996, based on data published by the Contact Lens Institute. The Company's
overall unit sales have increased at a compound annual growth rate of
approximately 81% since 1992, primarily due to increased sales of its lenses for
weekly disposable replacement regimens. During the same period, while the
overall average selling prices of all of the Company's lenses declined 50%, the
Company reduced its per unit production costs by approximately 64% by spreading
its relatively fixed manufacturing and operating costs over higher production
volumes, and by improving its manufacturing and packaging processes. As a
result, from 1992 to 1996, the Company's net sales and operating income
(excluding non-recurring charges in 1992) have increased at compound annual
growth rates of approximately 53% and 100%, respectively, while its operating
margins improved from 6.6% to 19.3%.
 
INDUSTRY OVERVIEW
 
     The soft contact lens industry is characterized by increasing lens
consumption, declining unit prices and intense competition among the eyecare
practitioners and retail chains that fit, prescribe and sell contact lenses.
Industry analysts estimate that approximately 50% of the world's population
needs some type of vision correction. In the United States alone, over 130
million people require some form of vision correction. Approximately 26 million
people in the United States, or 20% of those requiring vision correction, wear
contact lenses according to estimates by industry analysts, making the United
States the world's largest market for contact lenses. While contact lenses have
been available for decades, the advent of soft lenses in 1971 changed the
industry substantially and stimulated significant penetration of the eyeglass
market by dramatically reducing the discomfort of earlier rigid lenses.
 
     The first soft contact lenses were generally prescribed for replacement
every one to two years. Although they were significantly more comfortable than
hard contact lenses, they required an extensive cleaning routine, consisting of
daily cleaning with a surfactant cleanser and an additional weekly enzymatic
cleaning to reduce protein accumulation. Even with this cleaning program, these
lenses often became progressively less
 
                                       32
<PAGE>   34
 
comfortable to wear over time. Additionally, the long replacement schedule of
the lenses increased the likelihood of ocular health problems if the wearer did
not follow the required cleaning program. In response to these and other
factors, soft contact lenses for disposable replacement regimens were introduced
in 1988. These replacement regimens, in which lenses are to be replaced daily,
weekly or monthly, have spurred a rapid increase in contact lens consumption in
the United States. While contact lenses for disposable replacement regimens are
often made from the same or similar polymers and can have the same or similar
designs as lenses for annual replacement regimens, they are generally produced
at substantially higher volumes, sold in larger quantities and packaged in less
expensive materials. These factors allow the lenses to be sold at substantially
reduced per unit prices, making more frequent lens replacement economically
feasible for the consumer.
 
     Largely as a result of this increased frequency of lens replacement, the
number of soft contact lenses sold in the United States has increased at a
compound annual growth rate of approximately 20% from 1985 to 1995, according to
Health Products Research, a market research firm. This increase in unit sales
has provided increased manufacturing economies of scale that, together with
increased competition in distribution channels, has led to significant
reductions in average retail prices for lenses for disposable replacement
regimens. The Company believes that this, in turn, has led to further increases
in lens consumption. Despite the decline in per unit prices, as wearers switch
to more frequent replacement regimens, their annual expenditures for lenses
increase. For example, the Company's annual sales are from five to seven times
higher for a wearer following a bi-weekly replacement regimen than they are for
a wearer following an annual replacement regimen. As a result, total dollar
sales of contact lenses in the United States has increased at a compound annual
growth rate of approximately 11% per year from 1994 through 1996. The Company
believes that the United States market for contact lenses will continue to grow,
although at a slower rate, as wearers continue to shift towards more frequent
lens replacement regimens. In addition, according to industry studies, while the
United States and Canadian market represented approximately 50% of worldwide
contact lens unit sales volumes in 1996, market growth rates outside the United
States now exceed those in the United States. The Company believes that
international contact lens sales will continue to increase as low-priced,
disposable contact lenses become increasingly available in many international
markets.
 
     Most contact lenses are purchased from optometrists, either in private
practice or in retail chains, and from ophthalmologists in private practice. The
Company believes, based on a 1994 study sponsored by the American Academy of
Ophthalmology and management's experience in the eyecare industry, that the
eyecare profession suffers from a surplus of eyecare practitioners and believes
that the resulting competitive pressure has been exacerbated by the increased
prevalence of retail optical chains and mass merchandisers that provide eyecare
services. Eyecare practitioners in retail chains offer services and products
similar to those provided by practitioners in private practice but offer longer
hours in more convenient locations, such as shopping malls and other
high-traffic areas. Retail chains generally require higher patient volumes and
accordingly rely heavily on consumer advertising and promotional pricing to
generate sales. Consequently, the Company believes that competition to acquire
and retain patients has intensified.
 
     The typical eyecare practitioner in both the private practice and retail
chain channels depends heavily on sales of products, such as contact lenses and
eyeglasses. The Company believes, based on a 1996 industry survey, that the
typical optometric practice or retail optical chain realizes approximately
two-thirds of its revenue from sales of corrective products, such as contact
lenses and eyeglasses, and approximately one-third of its revenue from
professional services such as eye examinations. Since the need for vision
correction is chronic, repeat sales of contact lenses can provide the
practitioner with a recurring, predictable revenue base.
 
     While the introduction of disposable lens replacement regimens has led to
growth in the contact lens market, it has placed additional competitive pressure
on practitioners. Traditionally, patients purchased new lenses annually in
connection with their eye examinations. Today, a patient is still required to
see an eyecare practitioner initially to be fitted for contact lenses and to
receive a prescription. After the initial fitting, however, while the patient
may see the practitioner annually to monitor eye health, he or she may purchase
new contact lenses to refill the prescription three or four times per year. Most
patients select contact lenses based on the recommendation of their eyecare
practitioners, and accordingly practitioners have significant influence in
determining the brands of contact lenses worn by their patients. In addition,
because contact lens prescriptions are generally brand-specific, patients
typically continue to purchase the same brand for their
 
                                       33
<PAGE>   35
 
prescription refills. However, the prescribing practitioner risks losing the
recurring sales represented by prescription refills as nationally advertised
lens brands are now available through virtually every possible channel of
distribution, including mail-order companies and pharmacies.
 
     The Company believes that practitioners can increase their patient
retention and provide better ongoing patient care by providing
competitively-priced, high-quality products that are differentiated by brand
from those provided by competing channels. As a result, the Company believes
that there exist significant opportunities for manufacturers of contact lenses
that can effectively address these needs. Moreover, the Company believes that
the increased frequency of lens purchases resulting from the shift to lenses for
disposable replacement regimens can provide significant recurring revenues for
manufacturers that are able to produce and distribute large quantities of
high-quality lenses on a cost-effective basis.
 
STRATEGY
 
     The Company has successfully implemented a strategy based on addressing the
needs of eyecare practitioners. This strategy has enabled the Company to achieve
a leading position in the U.S. market for lenses for annual replacement
regimens. The Company is continuing to pursue this strategy by leveraging the
practitioner relationships and reputation resulting from this leading position
to increase its share of the growing disposable market segment. The Company
believes that its high-quality, efficient manufacturing technology and
cost-effective operations position it to profitably exploit the growth
associated with this high-volume segment. The principal elements of the
Company's strategy include:
 
          Focus Marketing on Eyecare Practitioners. The Company's sales and
     marketing efforts are directed at eyecare practitioners because the
     practitioner strongly influences the brand of lenses purchased by the
     patient. The Company advertises and promotes its products solely to
     practitioners rather than to consumers. In addition, the Company does not
     sell its lenses to mail-order companies, pharmacies and other distribution
     channels that do not provide the eyecare services necessary to confirm lens
     fit and monitor ocular health. By bar-coding each disposable unit shipped,
     the Company can identify any diversion of its lenses to non-eyecare
     practitioner channels. The Company structures its branding and marketing
     strategies so that the patient will be more likely to refill prescriptions
     from the practitioner or retail chain from whom he or she received the
     initial prescription. As a result, the Company believes that it assists
     eyecare practitioners in retaining patient reorders and improves
     practitioners' ability to monitor their patients' ongoing ocular health,
     thereby providing a significant incentive for practitioners to prescribe
     the Company's lenses.
 
          Employ Unique Brand Segmentation by Channel. The high-volume use of
     lenses for disposable replacement regimens has resulted in increased
     mass-market advertising of competing products and intensified competition
     across distribution channels. Unlike its larger competitors, which promote
     nationally advertised consumer brands across multiple distribution
     channels, the Company advertises and promotes its lenses for disposable
     replacement regimens under specific brand names for the private practice
     channel and other brand names for the retail chain channel. The Company
     also provides private label brands for its larger customers. Branding by
     distribution channel creates brand exclusivity and allows practitioners to
     differentiate lenses sold by them from those sold through competing
     channels, providing them with a greater ability to retain their patients'
     prescription refill business. The Company believes that, as a result, its
     channel-specific branding has become increasingly valuable to eyecare
     practitioners. By promoting the repeat purchase of lenses from the
     prescribing practitioner, the Company believes that its marketing
     strategies increase patient satisfaction and thereby encourage long-term
     loyalty to its products, while also motivating practitioners to prescribe
     its lenses.
 
          Produce Superior Performing Products. The Company believes that its
     contact lenses are superior in performance to those of its major
     competitors in terms of comfort and ease of handling. The Company's
     advanced dry cast molding process and sophisticated lens designs maximize
     wearers' comfort and improve shape retention of lenses, making them easier
     for wearers to handle. In addition, the Company's lenses are designed and
     manufactured to provide fitting characteristics similar to competitors'
     lenses. In general, this interchangeability enables the practitioner to
     switch a patient to the Company's
 
                                       34
<PAGE>   36
 
     lenses without extensive refitting time. These advantages enable the
     Company to market its lenses to eyecare practitioners for both existing, as
     well as new, contact lens wearers.
 
          Emphasize Low-Cost Efficient Manufacturing. With the growth of the
     high-volume disposable market segment, low-cost, scalable manufacturing has
     become increasingly important. The Company's dry cast molding technology
     allows it to manufacture high-quality lenses efficiently. With dry cast
     molding, the Company has been able to reduce its manufacturing costs per
     lens by approximately 64% over the last three years while increasing its
     production volumes approximately 470%. The Company believes that the
     increased unit volumes resulting from the growing disposable lens market
     and continued investment in automation and capacity will enable it to
     further reduce per unit production costs and increase production volumes.
 
          Minimize Cost-to-Serve. A substantial portion of the Company's costs
     consists of the costs required to sell and market lenses and to take and
     fill an order. The Company focuses on lowering these non-manufacturing
     costs, or "cost-to-serve," in order to increase its profitability and its
     flexibility to reduce prices. The Company's primary means of minimizing
     cost-to-serve are its use of telemarketing rather than a traditional direct
     sales organization and its use of advertising targeted to practitioners
     rather than to consumers. This strategy differentiates the Company from its
     competitors, and the Company believes that the cost of its average sales
     call is substantially lower than that of its competitors that rely on field
     sales representatives, as the Company's inside sales personnel can make
     more calls per day at a lower annual cost per salesperson. Unlike its
     leading competitors, which market their products to consumers through
     expensive mass-media campaigns, the Company further controls its operating
     expenses by directing its marketing solely to the eyecare practitioners who
     prescribe contact lenses. In addition, the Company is investing in
     increased automation in its distribution operations in order to maintain
     its low cost-to-serve.
 
          Expand Internationally Through Strategic Relationships. The Company
     believes that many international markets for soft contact lenses will grow
     at faster rates than the United States market and that this growth will be
     driven by increased availability of low-priced disposable lenses in
     developed markets such as Europe, Japan and Canada and by increased
     disposable income in emerging markets such as Asia and Latin America.
     However, many markets outside the United States do not have the level of
     demand necessary for local manufacturers to achieve the economies of scale
     required for low-cost lens production. Consistent with its strategy of
     minimizing cost-to-serve, the Company's international growth strategy is to
     establish strategic distribution and marketing relationships with regional
     optical companies, such as the contact lens division of the Carl Zeiss
     Company in Europe and Seiko Contactlens, Inc. in Japan, to capitalize on
     their existing market presence, customer relationships and local
     infrastructure. The Company believes that, as a result, it can target
     growing international markets effectively without significant investment in
     direct operations.
 
PRODUCTS
 
     The Company manufactures a broad line of soft contact lenses that it
believes provide performance that is superior to other leading products at
competitive prices. Soft contact lens performance is defined primarily by
comfort (how the lens feels on the eye), handling (ease of placement and
removal), acuity of vision and physiological response. These qualities, in turn,
are determined primarily by lens design and the manufacturing process. The
Company's lenses incorporate sophisticated designs, including extremely thin
edges, a lenticulated carrier and a low-edge apex, that provide a high level of
comfort, enhanced shape retention and ease of handling. The Company's dry cast
molding process further improves handling and comfort by consistently and
accurately reproducing these designs. In addition, the Company's lenses are
designed and manufactured to provide fitting characteristics similar to those of
competitors' lenses. In general, these characteristics enable the practitioner
to switch a patient to the Company's lenses without extensive refitting time.
The Company believes that this interchangeability, together with its lenses'
performance and price, allows practitioners to easily prescribe the Company's
lenses to existing, as well as new, contact lens wearers.
 
                                       35
<PAGE>   37
 
     The Company's contact lenses are made from flexible polymers containing 38%
or 55% water. The Company offers different brands for different replacement
regimens, from weekly and monthly replacement to annual replacement. A wearer's
replacement regimen is generally based on the recommendation of his or her
eyecare practitioner, who typically prescribes a lens brand targeted to that
regimen and who advises the wearer on the appropriate lens care procedures for
that regimen. However, the wearer may actually replace his or her lenses on a
more or less frequent basis. Given the basic functional similarity of lenses for
different replacement regimens, many of the Company's lenses for annual and
disposable replacement regimens are made from the same or similar polymers and
have the same or similar design specifications. Most of the Company's lenses
contain a light blue bulk-applied visibility tint that enables the wearer to see
and handle the lenses more easily, although some of the Company's more expensive
lenses for annual replacement contain a more expensive, individually applied
masked tint that improves handling and is less noticeable in the eye, and some
of the Company's lens are untinted. The Company's lenses for disposable and
annual replacement regimens are generally packaged in different quantities and
priced differently. See "Risk Factors -- Risk of Trade Practice Litigation;
Changes in Trade Practices."
 
     Within different replacement regimens, the Company offers daily-wear
lenses, to be removed, cleaned and disinfected each night, and extended-wear
lenses that may be worn continuously, night and day, for up to seven days. In
addition, within each replacement regimen, the Company offers lenses having
different design parameters, diameters and base curves to enable practitioners
to fit their patients better.
 
     Disposable Replacement Regimens
 
     Lenses marketed for disposable replacement regimens accounted for 65.7% and
73.8% of the Company's net sales in 1996 and the six months ended June 30, 1997,
respectively. See "Risk Factors -- Dependence on Single Product Line; Need to
Increase Sales of Lenses for Disposable Replacement Regimens."
 
     Weekly Replacement Regimens. The Company entered the growing weekly
disposable segment of the soft contact lens market with a 38% water content lens
in September 1993. The Company's introduction of a 55% water content lens in the
first quarter of 1995 provided a product directly competitive with the market
leader, Acuvue, which was the first soft contact lens to be marketed broadly in
the United States for weekly replacement. These lenses are marketed for
replacement every one to two weeks. The Company believes that its 55% water
lenses for weekly replacement can provide handling and comfort superior to that
provided by Acuvue, at a competitive price. The design and water content of the
55% water lens permit a high level of oxygen transmissibility and provide
increased comfort for overnight wear. A February 1997 independent study
comparing the Company's 55% water lens for weekly replacement to Acuvue found
that a substantial majority of the 70 patients studied preferred the Company's
lens for ease of use and comfort. This study reported that overall, 63% of these
70 patients preferred the Company's lens over the Acuvue lens. The Company
believes that its lenses for weekly replacement regimens have demonstrated
strong market acceptance, gaining U.S. market share steadily since their
introduction and representing approximately 8% (based on units sold) of the one
to two week disposable market segment in the United States in 1996. The Company
markets its weekly disposable lenses to independent practitioners under the
Hydron Biomedics, Clinasoft, Procon and Mediflex brands and to retail chains
under the UltraFlex 7/14 brand and private label brands. The Company packages
its lenses for weekly replacement in boxes, each containing six identical
blister-packed lenses.
 
     Monthly Replacement Regimens (Planned Replacement Lenses). The Company
markets its lenses for monthly replacement regimens primarily under the Hydron
ProActive 55, Edge III ProActive and UltraFlex SmartChoice brands. These lenses
are marketed for replacement every one to three months. This replacement regimen
provides a lower cost alternative to weekly replacement.
 
     Daily Replacement Regimens (Under Development). The Company is evaluating
the introduction of a low-cost lens for daily replacement. The product would be
packaged in boxes of 30 lenses. The Company believes that there may be
substantial demand for the convenience of a lens for single-day wear. However,
the Company believes that the level of demand for daily disposable lenses is
still uncertain. Certain of the Company's competitors have introduced, and
certain others plan to introduce, lenses for daily replacement. The Company
intends to evaluate the market response to their offerings before introducing
its own daily
 
                                       36
<PAGE>   38
 
disposable lens. In addition, because of the substantially greater volume
requirements and lower selling prices that the Company believes will be required
to support daily replacement, the Company does not intend to offer lenses for
this replacement regimen until it has significantly increased its manufacturing
capacity and decreased its per unit production costs. See "Risk
Factors -- Intense Competition" and "-- Manufacturing Capacity Constraints;
Risks Associated with Expansion and Automation of Manufacturing Operations."
 
     Annual Lens Replacement Regimens
 
     The Company is a leading provider of soft lenses for annual replacement
regimens in the United States. Annual replacement lenses accounted for 31.2% and
23.3% of the Company's net sales in 1996 and the six months ended June 30, 1997,
respectively. These lenses must be cleaned nightly, with an additional weekly
enzymatic cleaning to reduce protein accumulation. Patients generally wear these
lenses until they become dirty or uncomfortable (usually a year for 38% water
products and about nine months for 55% water products). The Company markets its
annual replacement lenses primarily under three brand names, Edge III, UltraFlex
and Hydron. These product lines include a number of lens designs to allow
practitioners to choose the lens that best meets their patients' needs. Under
both the Edge III and UltraFlex brands, the Company offers a low-priced,
daily-wear product, a thinner product, a product that is both thinner and larger
in diameter and a product that may be utilized as an extended-wear lens. The
Company packages its lenses for annual replacement regimens in single-lens vials
or blister packs.
 
     Specialty Lenses
 
   
     Specialty lenses accounted for approximately 2.7% and 2.2% of the Company's
net sales in 1996 and the six months ended June 30, 1997, respectively. Toric
lenses are designed to correct vision for people with astigmatism, which is
characterized by an irregularly shaped cornea. The Company offers daily wear
toric lenses under the Ultra T brand that are manufactured for the Company by a
third party. In addition, the Company manufactures a line of custom toric
lenses, produced to order in its Markham, Ontario facility, although the Company
expects to sell these operations to a third party. These custom lenses accounted
for less than one percent of the Company's net sales in 1996 and the first six
months of 1997. Bifocal contact lenses can help to correct presbyopia, or
age-related difficulty in focusing on near objects. The Company offers daily-
wear bifocal lenses under the Echelon brand that are cast-molded by the Company.
In addition, the Company produces its Versa-Scribe tinted lenses, sold in blue,
aqua and green, to enhance the color of the eye.
    
 
SALES AND MARKETING
 
     In the United States and the United Kingdom, the Company's products are
sold primarily by its 54-person inside sales force, based in South San Francisco
and the United Kingdom. In order to maintain a low cost-to-serve, the Company
has utilized an inside sales force since its inception. This inside sales force
relies on telemarketing to sell the Company's products to practitioners, both in
independent practice and retail chains. With over 40,000 practitioners in the
United States, the Company believes that this market can be reached effectively
and frequently through telemarketing, mailings, trade journals and trade shows,
at a relatively low cost. The Company's inside sales personnel can make
presentations to a significantly greater number of practitioners per day than
the traditional field sales representatives used by the Company's principal
competitors, at a lower annual cost per salesperson. The Company believes that
this sales efficiency provides it with a competitive advantage and contributes
to its low cost-to-serve. For larger national accounts, senior management also
frequently makes outside sales calls.
 
     In recruiting its sales personnel, the Company seeks well-educated
candidates who it believes will be capable of both discussing technical
information and developing relationships with practitioners. As part of a
continuing effort to ensure the motivation, professionalism and effectiveness of
its sales representatives, the Company provides each sales representative with
substantial training in a program that was developed by the Company and has been
used since its inception. This program typically includes two weeks of initial
training and at least two hours a week of continuing instruction. This training
emphasizes the development of personal relationships with customers and the
technical aspects of contact lens fitting and design. The Company's current
sales representatives average approximately three years with the Company,
providing a level of experience that the Company believes enables them to work
effectively with optometrists and ophthalmolo-
 
                                       37

gists. Each salesperson is assisted by a computer database that maintains each
practitioner's profile, monitors ongoing activities and orders, allows sales
personnel to enter information for follow-up calls and highlights dates for
return calls.
 
     The Company also utilizes distributors that resell the Company's contact
lenses primarily to independent practitioners. In 1996, sales through
distributors represented approximately 13% of the Company's United States sales
and a substantial majority of its international sales. The Company believes that
by using distributors, it increases the availability of its lenses to many
practitioners who prefer to utilize a single source for several brands of lenses
and manages the costs involved in numerous small orders. In addition, the
Company utilizes advertising targeted to practitioners, such as direct-mail and
advertisements in professional journals, to generate leads for its inside sales
force. The Company also provides customers with substantial merchandising
allowances and has developed a variety of promotional programs to offer lenses
at significantly reduced prices in order to encourage trial of its products.
 
     As a matter of policy, the Company does not sell lenses to mail-order
companies because to do so would be inconsistent with its strategy of focusing
on the practitioner and because they do not provide the regular eye examinations
necessary to check the fit of the lenses and monitor overall ocular health. To
control the distribution of its lenses for disposable replacement regimens, the
Company places serialized bar-codes on each disposable product box and blister
pack and routinely monitors product availability at mail-order companies. The
Company has a policy of terminating the supply of disposable lenses to its
customers who are found to have diverted products to a mail-order company. See
"Risk Factors -- Risk of Trade Practice Litigation; Changes in Trade Practices."
 
     In 1996, the Company sold its products to approximately 13,000 independent
practitioner accounts and approximately 80 retail chains. The Company's
customers in each of the past three years have included 18 of the top 20 United
States optical retailers. Thirteen of these top 20 U.S. retailers, as well as
key international corporate accounts such as Synsam in Scandinavia, have
selected the Company's lenses for their private label. No single customer
accounted for more than approximately 8% of the Company's net sales in 1996. The
Company's ten largest customers in 1996 represented approximately 27% of the
Company's net sales in that year.
 
     Product Branding. The Company has developed many different trademarked
brands for its lenses for disposable replacement regimens. Certain brands are
offered only to independent practitioners. Other brands are offered only to
retail chains. In addition, private label brands are offered to certain
high-volume customers that wish to develop their own brand recognition and
loyalty, and private practitioners (or groups of private practitioners) meeting
certain volume criteria can similarly purchase "semi-exclusive" brands that are
not widely offered to other practitioners in their local market. The Company
believes that this approach differentiates the Company from its leading
competitors, which typically rely heavily on expensive consumer advertising and
promotion of national brands to generate brand awareness and demand. With the
same nationally advertised and promoted brands of disposable lenses available in
a number of major distribution channels, often including mail-order companies
and pharmacies, patients can bypass their original eyecare provider when
purchasing replacement lenses. By marketing its lenses under different brands,
segmented by distribution channel, the Company believes that it can assist
eyecare professionals in retaining their patients and improve patients'
long-term eyecare. See "Risk Factors -- Risk of Trade Practice Litigation;
Changes in Trade Practices."

     International Markets. The Company anticipates that many international
markets for soft contact lenses will grow at faster rates than the United States
market, driven by increased availability of low-priced disposable lenses in
developed markets such as Europe, Japan and Canada and by increased disposable
income in emerging markets such as Asia and Latin America. However, many markets
outside the United States do not have the volume of demand necessary for local
manufacturers to achieve the economies of scale required for low cost lens
production. As a result, the Company's international strategy is to enter into
strategic distribution and marketing relationships with established regional
optical companies. The Company offers these companies lower cost lenses afforded
by its volume production efficiencies and the marketing benefits of a private
label brand, and they provide the Company with the benefits of their existing
market presence, customer relationships and local infrastructure. The Company
believes that this strategy permits it to target growing international markets
effectively without significant investment in direct operations. See "Risk
Factors -- Risks Relating to International Operations; Need to Increase Sales in
International Markets" and Note 13 of Notes to Consolidated Financial
Statements. The following summarizes the Company's international sales
operations:
 
          Europe. To expand its penetration of this growing market, the Company
     has developed strategic partnerships with a number of regional and local
     contact lens distributors including the contact lens division of the Carl
     Zeiss Company ("Zeiss"). In this relationship, Zeiss sells the Company's
     disposable contact lenses under its brand names on a non-exclusive basis
     throughout Europe. The Company also currently has distribution
     relationships in Europe and the Middle East serving a number of countries,
     as well as an inside sales organization based in Southampton, England that
     uses telemarketing and other sales methods in the United Kingdom similar to
     those used by the Company in the United States.
 
          Canada. The Company has a direct selling organization based in Ontario
     that uses field sales representatives as well as direct mail, journal
     promotion and cooperative merchandising allowance programs similar to those
     used by the Company in the United States. The Company also utilizes a small
     number of Canadian distributors to resell its products, primarily to
     independent eyecare practitioners.
 
          Latin America. Although the Company expects unit growth in the
     disposable segment of this emerging market, it also believes that unit
     sales of lenses for annual replacement regimens will grow at a much faster
     pace than in North America or Europe because of the lower level of consumer
     disposable income. To expand the Company's penetration of this growing
     market, the Company has entered into a number of non-exclusive distribution
     arrangements in Latin America.
 
                                       40
<PAGE>   41
 
          Asia. The Company believes that the growth of unit sales in this
     market will be driven primarily by sales of contact lenses for disposable
     replacement regimens, particularly in Japan. Unit sales of lenses for
     annual replacement regimens in East Asia are also expected to grow at a
     faster rate than in North America or Europe due to comparatively low levels
     of consumer disposable income. To capitalize on expected growth in the
     Japanese market, the Company has formed a strategic distribution
     relationship with Seiko Contactlens, Inc., which is responsible for
     obtaining local regulatory approvals and will distribute the Company's
     lenses to Japanese eyecare practitioners through its network of
     approximately 80 direct sales representatives. The Company has also
     established distribution relationships with other soft contact lens
     distributors in a number of countries in the Asian market.
 
DISTRIBUTION
 
     The Company's distribution operations provide its customers with rapid and
reliable deliveries of its products in a cost-effective manner. Because the
Company's customers place both small orders for individual patients and large
inventory stocking orders, the Company's fulfillment system has the flexibility
to receive, fill and ship orders as small as a single lens and as large as tens
of thousands of lenses. Customers may place orders by toll-free telephone call
or by facsimile. Certain of the Company's larger customers use the Company's
electronic data interchange ("EDI") services to place orders and receive order
acknowledgments, invoices, inventory status reports and customized pricing
information online, improving efficiency and timeliness for both the Company and
the customer. If the product is in stock, customer orders received by 2:00 p.m.
local time are generally shipped the same day.
 
     The Company maintains its primary warehouse and distribution facilities in
South San Francisco, California; Eastleigh, United Kingdom; and Markham,
Ontario. The largest and most sophisticated of these distribution centers is the
South San Francisco location, which primarily serves customers in the United
States and Latin America. Customers in Europe and Asia are primarily served from
the Eastleigh, United Kingdom facility and customers in Canada are primarily
served from the Markham, Ontario facility. Lenses are labeled and boxed at the
distribution center based on actual and anticipated customer orders. In 1996, an
average of approximately 2,100 orders were placed daily at the South San
Francisco facility from customers in North and Latin America and downloaded to
the distribution center for picking and shipping.
 
     To further improve its cost-to-serve, the Company is currently testing, and
plans to implement, a highly computerized and automated retrieval system at its
South San Francisco facility. This system is designed to incorporate advanced
handling processes such as automatic dispensing, automated conveyors and radio
frequency dispatch. These processes will be integrated by software that, in
turn, is integrated into the Company's order entry system, allowing orders to be
downloaded, stocking locations determined and fulfillment instructions delivered
automatically.
 
MANUFACTURING
 
     Substantially all of the Company's products are manufactured in facilities
in Santa Isabel, Puerto Rico and in Eastleigh, United Kingdom. The Company
produces its lenses primarily through a manufacturing process known as dry cast
molding. This process uses a single use, two-part plastic mold that is
manufactured by injection-molding machines utilizing high-precision optical
tooling that is also made by the Company. A liquid monomer mixture is dispensed
into the mold and polymerized to form a finished dry lens. The mold containing
the polymerized lens can be inventoried for an extended period under proper
conditions. The dry lens, once removed from the mold, is immersed in a fluid
bath to extract unreacted monomer and to be hydrated and is then inspected,
packaged and sterilized. Each of the Puerto Rico and United Kingdom plants can
generally hydrate dry lenses manufactured by the other. These capabilities
substantially increase the efficiency and flexibility of the Company's
manufacturing operations.
 
     The Company's dry cast molding process enables the Company to reproduce
consistently the sophisticated designs of its lenses, including the lenticulated
carrier and low-edge apex that provide enhanced shape retention and superior
handling characteristics. In addition, the Company believes that this process
allows the reproduction of lenses that are designed to provide fitting
characteristics similar to those of leading
 
                                       41
<PAGE>   42
 
competitors' lenses, regardless of their manufacturing process. The Company also
believes that the dry cast molding process provides advantages over certain
alternate production methods in yield, throughput efficiency and performance.
For example, each dry lens in the Company's cast molding process emerges from
the mold completely finished, eliminating the need for additional polishing.
This cast molding process reduces manufacturing steps and facilitates automated
handling and inspection. The Company relies on a non-exclusive, perpetual,
irrevocable patent license for a significant element of its dry cast molding
technology. See "-- Trademarks, Trade Secrets and Patent Licenses." In addition
to dry cast molding, certain of the Company's competitors utilize wet cast
molding, lathing or spin-casting processes. While the Company also manufactures
certain low-volume lenses utilizing lathing, this process accounts for less than
2% of its total production.
 
     The Company believes that dry cast molding is a highly scalable process,
which makes it well suited to address the high-volume requirements of the
growing disposable market. Using this technology, the Company has been able to
increase production volumes by approximately 470% from 1993 to 1996. The
disposable market, however, is relatively price-sensitive, and lenses for
disposable replacement regimens generally have significantly lower selling
prices than lenses for annual replacement regimens. The Company believes that
its ability to compete effectively in this growing market will depend on its
ability to continue to reduce its per unit production costs while increasing
manufacturing capacity and maintaining the high quality of its products.
 
     The Company believes that reducing its manufacturing costs requires
increased automation to further improve manufacturing efficiencies and yields,
improved packaging designs that utilize lower cost materials and larger
production volumes to take advantage of economies of scale. While the Company
has implemented a number of cost reduction measures, such as blister packaging,
hot water extraction, automatic demolding and in-monomer tinting over the past
several years, the most significant improvements are expected to come from the
planned implementation of additional production lines incorporating a new
automated process based on the Company's current dry cast molding technology.
This automated process is currently being developed in a joint effort between
the Company and an engineering consulting firm. Initial design has been
substantially completed, and the Company has placed orders for much of the
equipment necessary for the first of the planned new production lines. This
first line is expected to be operational in 1998. The automated process is
designed to integrate standard components such as automated handling systems,
conveyors, robotics and video inspection into the manufacturing line. The
Company believes that the new automated process will enable it to reduce
significantly the labor content of production as well as unit packaging costs
while increasing yields and efficiencies through improved controls and
consistency of environment. The Company believes that the automated production
lines will be capable of manufacturing considerably greater volumes while
occupying less space than the Company's existing lines and will be installed in
both the United Kingdom and Puerto Rico locations within the next two years. The
Company currently expects to invest approximately $44 million in capital
expenditures on these automated production lines through the year 2000. See
"Risk Factors -- Manufacturing Capacity Constraints; Risks Associated with
Expansion and Automation of Manufacturing Operations."
 
     Over the past two years, the Company at times has experienced significant
backorders for certain of its products, including lenses for disposable
replacement regimens. These backorders resulted primarily from customer demand
for certain products being in excess of the Company's inventory and short-term
production capabilities as well as the Company's inability to gain timely FDA
clearance or approval for certain products. The Company is developing expanded
production capacity and an integrated enterprise-wide computer system to manage
the supply chain dynamics of forecasting, manufacturing, labeling and stocking
of its products. The level of backorders is currently minimal and is limited to
certain low-volume products.
 
     The Company's success will depend in part upon its ability to increase its
production volume on a timely basis while maintaining product quality, reducing
per unit production costs and complying with the FDA's GMP regulations. There
can be no assurance that the Company will not encounter difficulties in
expanding and automating its manufacturing facilities and increasing production,
including problems involving production yields, quality control, construction
delays and shortages of qualified personnel. The Company's failure to reduce per
unit production costs and maintain product quality could have a material adverse
effect on the Company's business, financial condition and results of operations.

Operations."
 
FACILITIES
 
     The Company's principal administrative, sales, marketing, customer service,
packaging and distribution facility is located in South San Francisco,
California. The Company's principal manufacturing facilities are located near
Southampton, United Kingdom, and in Santa Isabel, Puerto Rico. The Company also
maintains sales offices in Canada, Hungary and the United Kingdom.
 
     Rapid growth in sales volumes has required that the Company increase its
capacity by adding manufacturing space. The Company's first United Kingdom
manufacturing facility was established in 1988 and operated by PLL until 1992,
when it was acquired by the Company. The Company opened its second United
Kingdom manufacturing facility in 1996. The Company's Puerto Rican manufacturing
facility was acquired in late 1992 as part of the American Hydron acquisition.
This facility is now operating at or near capacity. As part of the Company's
plan to increase its manufacturing capacity, it intends to relocate its Puerto
Rican manufacturing facilities to a substantially larger new facility to be
constructed and leased near Santa Isabel, Puerto Rico. The Company is in the
process of negotiating the terms for the construction and leasing of the new
manufacturing facility with the Puerto Rican development agency. The Company
expects to begin construction during the third quarter of 1997. Until the new
Puerto Rican facility is completed, the Company intends to utilize excess
capacity in the United Kingdom to meet any requirements for increased volumes of
lens production. See "-- Manufacturing."
 
     The following table describes the Company's principal facilities as of June
30, 1997:

RESEARCH AND DEVELOPMENT
 
     The Company's research and development efforts are focused primarily on the
development of automated manufacturing processes to increase the efficiency and
capacity of the manufacturing operation. See "-- Manufacturing." In addition,
the Company is engaged to a limited extent in development of new soft contact
lens products and additional features. For example, the Company intends to
develop lenses that absorb ultraviolet light and is evaluating the introduction
of lenses designed for daily disposable replacement regimens. See "-- Government
Regulation." During the years ended December 31, 1994, 1995 and 1996, and the
six months ended June 30, 1997, expenditures for research and development
(including obtaining regulatory approvals) were approximately $900,000, $1.0
million, $1.1 million and $1.1 million, respectively. See "Risk Factors -- Risk
of New Products and Technological Change."

<PAGE>   44
 
TRADEMARKS, TRADE SECRETS AND PATENT LICENSES
 
     The Company believes that its trademarks are among its most valuable assets
and has numerous trademark registrations in the United States, Europe and other
foreign countries. The Company's channel-specific branding strategy is dependent
on the Company's strategic use of its trademark portfolio, as the trademark for
each product brand is generally registered. The Company licenses the Hydron
trademarks under a license agreement that prohibits the use of those trademarks
outside of the Americas. The Company believes that there are no currently
pending challenges to the use or registration of any of the Company's material
trademarks. There can be no assurance, however, that the Company's trademarks do
not or will not violate the proprietary rights of others, that they would be
upheld if challenged or that the Company would, in such an event, not be
prevented from using its trademarks, any of which could have a material adverse
effect on the Company and its business.
 
     The Company has obtained non-exclusive licenses from third parties to
patents for certain contact lens designs and manufacturing technologies used in
the production of its products. Pursuant to a patent license agreement with
several parties, including Geoffrey and Anthony Galley, principal stockholders
of the Company, the Company has obtained a perpetual, fully paid, worldwide,
non-exclusive, irrevocable license to certain patents and patent applications
covering technology that is significant in the Company's dry cast molding
processes. See "Certain Transactions -- OSL Acquisition and Related Litigation."
The Company has also obtained non-exclusive, fully paid, perpetual, worldwide
licenses to use certain technology relating to the tinting of lenses and to
manufacture a monomer used to produce certain of its lenses. In addition, the
Company licenses technology used in manufacturing its toric and bifocal contact
lenses under non-exclusive license agreements that limit the sales of products
manufactured using the licensed technology to the Americas. The Company believes
that it has all patent licenses that are necessary for the conduct of the
Company's business. However, to the extent the Company desires or is required to
obtain additional licenses to patents or proprietary rights of others, there can
be no assurance that any such licenses will be available on terms acceptable to
the Company, if at all.
 
     In addition to trademarks and patent licenses, the Company owns certain
trade secrets, copyrights, know-how and other intellectual property. The Company
seeks to protect these assets, in part, by entering into confidentiality
agreements with certain of its business partners, consultants and vendors. There
can be no assurance that these agreements will not be breached, that the Company
will have adequate remedies for any such breach or that the Company's trade
secrets and other intellectual property will not otherwise become known or be
independently developed by others and thereby become unprotected. Furthermore,
no assurance can be given that competitors will not independently develop
substantially equivalent proprietary information and techniques or otherwise
gain access to the Company's proprietary technology or that the Company can
meaningfully protect its rights in unpatented proprietary technology.
 
     The Company's policy is to prosecute and defend its key trademarks, trade
secrets and proprietary technology aggressively. The defense and prosecution of
intellectual property suits and related administrative proceedings are both
costly and time-consuming. There can be no assurance that the prosecution and
defense of the Company's intellectual property will be successful or that the
Company will be able to secure adequate intellectual property protections in the
future. The protection of intellectual property in certain foreign countries is
particularly uncertain. Adverse determinations in a judicial or administrative
proceeding or failure to obtain necessary licenses could prevent the Company
from manufacturing and selling its products, and such events would have a
material adverse effect on the Company's business, financial condition and
results of operations. See "Risk Factors -- Dependence on Trademarks, Patent
Licenses and Trade Secrets; Risk of Intellectual Property Infringement" and
"Certain Transactions -- OSL Acquisition and Related Litigation."
 
COMPETITION
 
     The market for soft contact lenses is intensely competitive and is
characterized by decreasing prices for many products. The Company's products
compete with the products offered by a number of larger companies including
Johnson & Johnson, Ciba-Geigy, Bausch & Lomb and Wesley Jessen. Most of the
Company's competitors have substantially greater financial, manufacturing,
marketing and technical resources, greater
 
                                       44
<PAGE>   45
 
market penetration and larger manufacturing volumes than the Company. Among
other things, these advantages may afford the Company's competitors greater
ability to manufacture large volumes of lenses, reduce product prices and
influence customer buying decisions. The Company believes that certain of its
competitors are expanding, or are planning to expand, their manufacturing
capacity, and to implement new, more automated manufacturing processes in order
to support anticipated increases in volume. As many of the costs involved in
producing contact lenses are relatively fixed, if a manufacturer can increase
its volume, it can generally reduce its per unit costs and thereby increase its
flexibility to reduce prices. In addition, competitors may reduce prices to
achieve the sales volumes necessary to utilize their increased capacity. Price
reductions by competitors could make the Company's products less competitive,
and there can be no assurance that the Company would be able to reduce its
prices in response. The Company's ability to respond to competitive pressures by
decreasing its prices without adversely affecting its gross margins and
operating results will depend on its ability to decrease its costs per lens. Any
significant decrease in the Company's costs per lens will depend, in part, on
the Company's ability to increase its sales volume and production capacity.
There can be no assurance that the Company will be able to continue to increase
its sales volume or reduce its per unit production costs. The failure of the
Company to respond to competitive pressures, and particularly price competition,
in a timely manner would have a material adverse effect on the Company's
business, financial condition and results of operations. In addition, in
response to competition, the Company may reduce prices, increase cooperative
merchandising allowances or otherwise increase spending, any of which may also
adversely affect its business, financial condition and results of operations.
See "Risk Factors -- Manufacturing Capacity Constraints; Risks Associated with
Expansion and Automation of Manufacturing Operations."
 
     Soft contact lens manufacturers have generally differentiated themselves
from their competitors on the basis of product performance, marketing,
distribution channels and price. The Company believes that it is able to
distinguish its products on the basis of performance advantages and cost to
eyecare professionals and patients. Since the purchase of contact lenses
requires a prescription in the United States, the Company also competes on the
basis of its relationships and reputation with eyecare practitioners. There can
be no assurance that the Company will continue to so distinguish its products or
that it will be able to realize the anticipated reductions in its per unit
production costs.
 
     The market for contact lenses is shifting from lenses marketed for annual
replacement regimens, where the Company has significant experience and a leading
market position, to lenses for disposable replacement regimens, where the
Company is less experienced and has a smaller market share. The disposable lens
segment is particularly competitive and price-sensitive and is currently
dominated by the Acuvue product produced by Johnson & Johnson. The Company
believes that the per unit production costs of Johnson & Johnson and certain of
the Company's other competitors are currently lower than those of the Company. A
significant price reduction by Johnson & Johnson or certain of these other
competitors could limit or reduce the Company's market share in the disposable
lens segment and, as a result, could materially adversely affect the Company's
business, financial condition and results of operations. In addition, the lenses
currently offered in the United States by the Company in the disposable lens
segment are marketed for weekly and monthly replacement regimens. Certain of the
Company's competitors have introduced lenses for daily replacement at lower
prices than their current weekly and bi-weekly disposable lenses. The Company's
ability to enter and to compete effectively in the market for daily disposable
lenses will depend in large part upon the Company's ability to expand its
production capacity and reduce its per unit production costs. Additionally, as
contact lenses for different replacement regimens are often similar, the ability
of competitors to reduce their per unit costs for daily disposable lenses may
also permit them to reduce their costs for lenses marketed for other replacement
regimens. Such reductions, if not matched by the Company, could significantly
adversely impact the Company's ability to compete over a much broader level of
products. See "Risk Factors -- Dependence on Single Product Line; Need to
Increase Sales of Lenses for Disposable Replacement Regimens."
 
     The Company also encounters competition from manufacturers of eyeglasses
and from alternative technologies, such as surgical refractive procedures
(including new refractive laser procedures such as PRK, or photorefractive
keratectomy, and LASIK, or laser in situ keratomileusis). If surgical refractive
procedures become increasingly accepted as an effective and safe technique for
permanent vision correction, they could substantially reduce the demand for
contact lenses by enabling patients to avoid the ongoing costs and
 
                                       45

inconvenience of contact lenses. Accordingly, there can be no assurance that
these procedures, or other alternative technologies that may be developed in the
future, will not cause a substantial decline in the number of contact lens
wearers and thus have a material adverse effect on the Company's business,
financial condition and results of operations. See "Risk Factors -- Intense
Competition" and "Risk Factors -- Risk of New Products and Technological
Change."
 
GOVERNMENT REGULATION
 
     The FDC Act, other statutes, regulations of the FDA and other agencies as
well as state laws govern the preclinical and clinical testing, manufacture,
labeling, distribution, sale, marketing, advertising and promotion of medical
devices such as contact lenses. Noncompliance with applicable regulations can
result in, among other things, fines, injunctions, product recall or product
seizures, operating restrictions (including suspension of production and
distribution), refusal of the FDA to grant approval of a PMA or clearance of a
510(k), withdrawal of previously granted marketing approvals or clearances, and
criminal prosecution. Sales of the Company's products outside the U.S. are
subject to regulatory requirements that, while generally comparable to those in
the U.S., vary widely from country to country.
 
     FDA Regulation. For purposes of the applicable statutes and regulations,
the Company's products are generally treated as "medical devices." With
exceptions for certain medical devices first marketed before May 28, 1976, prior
to their commercial sale in the United States, medical devices must be cleared
or approved by the FDA or be exempted from the requirement of FDA clearance or
approval. In general, the regulatory process can be lengthy, expensive and
uncertain, and securing FDA clearances or approvals may require the submission
of extensive clinical data together with other supporting information to the
FDA.
 
     In the United States, medical devices are classified as Class I, II or III,
on the basis of the controls deemed by the FDA to be necessary to reasonably
ensure their safety and effectiveness. Class I devices are subject to general
controls (e.g., labeling, 510(k) notification and adherence to FDA-mandated
current GMP requirements), and Class II devices are subject to general controls
and special controls (e.g., performance standards). Generally, Class III devices
are those that must receive premarket approval by the FDA to ensure their safety
and effectiveness (e.g., life-sustaining, life-supporting and implantable
devices) and also include most devices that were not on the market before May
28, 1976 ("new medical devices") and for which the FDA has not made a finding of
"substantial equivalence" based on a 510(k). Class III devices usually require
clinical testing and FDA approval prior to marketing and distribution.
 
     The Company's daily-wear products have been classified as Class II devices
subject to the 510(k) pre-market notification process, while the Company's
extended-wear products have been classified as Class III devices subject to the
PMA requirements. Regulation of the Company's daily-wear products under the
pre-market notification process dictates that new product introductions in this
category be preceded by FDA clearance of a 510(k) pre-market notification
containing information which establishes the new product as substantially
equivalent to a legally marketed Class I or II medical device or to a legally
marketed Class III device that does not itself require an approved PMA prior to
marketing ("predicate device"). A 510(k) must contain information to support a
claim of substantial equivalence, and this information may include laboratory
test results or the results of clinical studies of the device in humans. The FDA
has no specific time limitation by which it must respond to a 510(k). The FDA
may determine that a device is not "substantially equivalent" to a predicate
device or that additional information is needed before a substantial equivalence
determination can be made. The premarket notification process generally takes
five to twelve months without clinical data, or twelve to eighteen months or
more if clinical data are required to be included in the notifications but it
may take longer, and 510(k) clearance may never be obtained. The range of
clinical data required to be included in a 510(k), if any, or a PMA application
varies depending on the nature of the new product or product modification.
Generally, the 510(k) notifications filed by the Company do not require clinical
data, and, if clinical data are required, the trial is short-term. If the
Company is unable to establish to the FDA's satisfaction that a new product is
substantially equivalent to a predicate device, extensive preclinical and
clinical testing will be required, additional costs will be incurred, and FDA
approval of a PMA for the product will be required prior to market entry. Such
approval, which cannot be assured in a timely manner or at all, generally takes
at least eighteen to twenty-four months, and can take substantially longer.
 
                                       46
<PAGE>   47
 
     Regulation of the Company's extended-wear products as Class III devices
requires that the Company submit a PMA to the FDA and obtain its approval of the
application prior to marketing such products in the United States. A PMA must be
supported by valid scientific evidence that typically includes extensive data,
including data from preclinical testing and human clinical trials to demonstrate
the safety and effectiveness of the device. The FDA ordinarily requires the
performance of at least two independent, statistically significant human
clinical trials that must demonstrate the safety and effectiveness of the device
in order to obtain FDA approval of the PMA. If the device presents a
"significant risk," the sponsor of the trial (usually the manufacturer or the
distributor of the device) is required to file an investigational device
exemption ("IDE") application with the FDA prior to commencing human clinical
trials. The IDE application must be supported by data, typically including the
results of animal and laboratory testing. If the IDE application is approved by
the FDA and the study protocol is approved by one or more appropriate
institutional review boards ("IRBs"), human clinical trials may begin at a
specific number of investigational sites with a specific number of patients, as
approved by the FDA. If the device presents a "nonsignificant risk" to the
patient, a sponsor may begin the human clinical trials after obtaining approval
of the study protocol by one or more appropriate IRBs, but FDA approval of an
IDE is not necessary unless the FDA notifies the sponsor that an IDE application
is required. An IDE supplement must be submitted to, and approved by, the FDA
before a sponsor or an investigator may make a change to the investigational
plan that may affect its scientific soundness or the rights, safety or welfare
of human subjects. The FDA has the authority to re-evaluate, alter, suspend or
terminate clinical testing based on its assessment of data collected throughout
the trials.
 
     The PMA must also contain the results of all relevant bench tests,
laboratory and animal studies, a complete description of the device and its
components, and a detailed description of the methods, facilities and controls
used to manufacture the device. In addition, the submission must include the
proposed labeling and promotional labeling. Once the FDA accepts a PMA
submission for filing, the FDA begins an in-depth review of the PMA. An FDA
review of a PMA generally takes from twelve to eighteen months from the date the
PMA is accepted for filing, but may take significantly longer if the FDA
requests additional information and if the sponsor files any major amendments to
the PMA. The review time is often significantly extended by the FDA's request
for clarification of information already provided in the submission. Toward the
end of the PMA review process, the FDA generally will conduct an inspection of
the manufacturer's facilities to ensure that the facilities are in compliance
with the applicable GMP requirements.
 
     If the FDA's evaluations of both the PMA and the manufacturing facilities
are favorable, the FDA will issue either an approval letter (order) or an
"approvable letter" containing a number of conditions that must be met in order
to secure approval of a PMA. When and if those conditions have been fulfilled to
the satisfaction of the FDA, the agency will issue an order approving the PMA
and authorizing commercial marketing of the device for certain indications. If
the FDA's evaluation of the PMA or manufacturing facilities is not favorable,
the FDA will deny approval of the PMA or issue a "not approvable letter." The
FDA may also determine that additional preclinical testing or human clinical
trials are necessary, in which case approval of the PMA could be delayed for
several years while additional testing or trials are conducted and submitted in
an amendment to the PMA. The PMA process can be expensive, uncertain and
lengthy, and a number of devices for which FDA approval has been sought by other
companies have never been approved for marketing.
 
     Even if 510(k) clearance or PMA approval is obtained, this clearance or
approval can be withdrawn by the FDA due to the failure to comply with
regulatory requirements or the occurrence of unforeseen problems following
initial clearance or approval. Modifications to existing 510(k)-cleared devices,
including changes in design, material, or manufacturing process that could
significantly affect safety or effectiveness, require submission and clearance
of new 510(k) notifications as do significant changes in labeling, e.g., a
change in indications for use. Modifications to a device that is the subject of
an approved PMA, its labeling, or manufacturing process ordinarily require
approval by the FDA of PMA supplements or new PMAs. Supplements to a PMA
typically require the submission of similar information as is required for an
initial PMA, except that the supplement is generally limited to that information
needed to support the proposed change from the product covered by the original
PMA. The approval of supplemental PMAs requires approximately one to two years.
 
                                       47
<PAGE>   48
 
     All of the products currently marketed by the Company have received 510(k)
clearance or PMA approval. The Company anticipates that its planned
ultraviolet-absorbing daily-wear lens will be regulated as a Class II medical
device, requiring submission and clearance of a 510(k), and that its planned
ultraviolet-absorbing extended-wear lens will be regulated as a Class III
medical device, requiring submission and approval of a PMA supplement. There can
be no assurance that these planned products or any other future products will
receive FDA marketing clearance or approval on a timely basis or at all, or that
its new daily-wear lens will not be subjected to the PMA process. The Company
has made minor modifications to its lenses which it believes do not require the
submission and clearance of new 510(k) notifications or the submission and
approval of PMA supplements. There can be no assurance, however, that the FDA
will agree with any of the Company's determinations not to submit new 510(k)
notifications or PMA supplements for these changes, that the FDA will not
require the Company to cease sales and distribution while seeking clearances of
510(k) notifications or approvals of PMA supplements for the changes, or that
such clearances and approvals, if required, will be obtained in a timely manner
or at all.
 
     The FDC Act requires that medical devices, including contact lenses, be
manufactured in accordance with the FDA's GMP regulations. These regulations
require, among other things, that (i) the manufacturing process be regulated,
controlled and documented by the use of written procedures, and (ii) the ability
to produce devices which meet the manufacturer's specifications be validated by
extensive and detailed testing of every aspect of the process. The regulations
also require detailed record keeping and investigation of any deficiencies in
the manufacturing process or in the products produced. Manufacturing facilities
are subject to FDA inspection on a periodic basis to monitor compliance with GMP
requirements. If violations of the applicable regulations are noted during FDA
inspections of manufacturing facilities, the FDA can prohibit further
manufacturing, distribution and sale of the devices until the violations are
cured. On October 7, 1996, the FDA published a revision of its GMP requirements,
incorporating them into a new regulation called the quality system ("QS")
regulation. The QS regulation requires, among other things, pre-production
design controls, purchasing controls and maintenance of service records. The QS
regulation became effective June 1, 1997, except that the FDA has stated that,
as long as manufacturers are taking reasonable steps to come into compliance
with the design control requirements, the FDA will not initiate action
(including enforcement cases) based on a failure to comply with these
requirements before June 1, 1998. Once in effect, the QS regulation is expected
to increase the cost of complying with FDA GMP and related requirements. The
Company believes that its facilities are in compliance with GMP regulations and
that the planned automation of its manufacturing facilities will not require FDA
approval.
 
     The Company is also required to register as a medical device manufacturer
with the FDA. Devices marketed in the United States are subject to pervasive and
continuing regulatory oversight by the FDA and other agencies, and the Company
is subject to periodic inspection and record-keeping requirements. As a medical
device manufacturer, the Company is further required to comply with FDA
requirements regarding the reporting of allegations of death or serious injury
associated with the use of its medical devices, as well as product malfunctions
that would likely cause or contribute to death or serious injury if the
malfunction were to recur. Other FDA requirements govern product labeling and
prohibit a manufacturer from marketing a device with a cleared 510(k) or an
approved PMA for an uncleared or unapproved indication. Failure to comply with
applicable regulatory requirements can result in a wide variety of severe
administrative, civil, and criminal sanctions and penalties. See "Risk
Factors -- Risks of Regulatory Action."
 
     International Regulation. Sales of medical devices outside the U.S. are
subject to foreign regulatory requirements that vary widely from country to
country. These laws and regulations range from simple product registration
requirements in some countries to complex clearance and production controls such
as those described above in others. As a result, the processes and time periods
required to obtain foreign marketing approval may be longer or shorter than
those necessary to obtain FDA approval. These differences may affect the
efficiency and timeliness of international market introduction of the Company's
products, and there can be no assurance that the Company will be able to obtain
regulatory approvals or clearances for its products in foreign countries.
 
     Medical devices sold or marketed in the European Union ("EU") are subject
to the EU's medical devices directive. Under this directive, CE mark
certification procedures became available for medical
 
                                       48
<PAGE>   49
 
devices, and the successful completion of such procedures would allow certified
devices to be marketed in all EU countries. In order to obtain the right to
affix the CE mark to its products, medical device companies must obtain
certification that its processes meet European quality standards and establish
that the product is considered safe and fit for its intended purpose. After June
14, 1998, medical devices other than active implants and in vitro diagnostic
products may not be sold in EU countries unless they display the CE mark.
Although member countries must accept for marketing medical devices bearing a CE
marking without imposing further requirements related to product safety and
performance, each country may require the use of its own language or labels and
instructions for use.
 
     The Company may also have to obtain additional approvals from foreign
regulatory authorities in order to sell its products in non-EU countries. Some
countries have historically permitted human studies earlier in the product
development cycle than regulations in the United States permit. Other countries,
such as Japan, have requirements similar to those of the United States. This
disparity in the regulation of medical devices may result in more rapid product
clearance in certain countries than in the United States, while approvals in
countries such as Japan may require longer periods than in the United States.
Seiko Contactlens Inc., the Company's distributor in Japan, will be responsible
for management of clinical trials and obtaining regulatory approval for the
Company's products, and such approval will therefore be outside the Company's
control. Accordingly, there can be no assurance as to when or whether such
approval will be received.
 
     Other Regulation. The Company is also subject to numerous federal, state
and local laws relating to such matters as safe working conditions,
manufacturing practices, environmental protection, fire hazard control and
disposal of hazardous or potentially hazardous substances. There can be no
assurance that the Company will not be required to incur significant costs to
comply with such laws and regulations in the future or that compliance with such
laws or regulations will not have a material adverse effect upon the Company's
ability to do business.
 
     The Company's success depends to a significant extent upon the success of
its customers in the retail optical industry. These customers are subject to a
variety of federal, state and local laws, regulations and ordinances, including
those regarding advertising, location and design of stores, products sold and
qualifications and practices of the industry. The state and local legal
requirements vary widely among jurisdictions and are subject to frequent change.
Furthermore, numerous health-care related legislative proposals have been made
in recent years in the United States Congress and in various state legislatures.
The potential impact of these proposals with respect to the business of the
Company's customers is uncertain, and there is no assurance that the proposals,
if adopted, would not have a material adverse impact on the Company.
 
     There is substantial United States federal and state governmental
regulation related to the prescribing of contact lenses. These regulations
relate to who is permitted to prescribe and fit contact lenses, the prescriber's
obligation to provide prescriptions to its patients, the length of time a
prescription is valid, the ability or obligation of prescribers to prescribe
lenses by brand rather than by generic equivalent or specification, and other
matters. Although these regulations primarily affect contact lens prescribers,
and not manufacturers or distributors of lenses such as the Company, changes in
these regulations, or their interpretation or enforcement, could adversely
affect the effectiveness of the Company's marketing strategy to eyecare
practitioners, most notably the effectiveness of the Company's channel-specific
and private label branding strategies. Additionally, given the Company's
strategic emphasis on focusing its marketing efforts on eyecare practitioners
rather than consumers, the Company may be more vulnerable than its competitors
to changes in current trade practices. Adverse regulatory or other decisions
affecting eyecare practitioners, or material changes in the selling and
prescribing practices for contact lenses, could have a material adverse affect
on the Company's business, operating results and financial condition.
 
PRODUCT LIABILITY AND INSURANCE
 
   
     The Company has in the past been, and continues to be, subject to product
liability claims and lawsuits, and the Company's Canadian subsidiary is
currently a defendant in one such lawsuit, filed by an individual in 1997 in the
Province of Ontario, Canada, alleging that the Company's lenses injured the
plaintiff's cornea and seeking damages of Can.$500,000 plus interest and costs.
Because contact lenses are medical devices, the
    
 
                                       48
<PAGE>   50
 
Company faces an inherent risk of exposure to product liability claims in the
event that the use of its products results in personal injury. The Company also
faces the possibility that defects in the design or manufacture of its products
might necessitate a product recall. From time to time, the Company has received,
and may continue to receive, complaints of significant patient discomfort,
including corneal complications, while using the Company's contact lenses. In
certain cases, the reasons for the problems have never been established. In
addition, on two occasions, in 1995 and 1997, the Company has recalled limited
volumes of certain of its product because certain labels on the vial or blister
did not match the enclosed lens. Although the Company has not experienced
material losses to date due to product liability claims or product recalls,
there can be no assurance that the Company will not experience such losses in
the future, that insurance coverage will be adequate to cover such losses, or
that insurance coverage will be available on acceptable terms or at all. The
Company maintains product liability insurance with coverage of $1 million per
occurrence and an annual aggregate maximum of $2 million with umbrella coverage
of $10 million. A product liability or other judgment against the Company in
excess of the Company's insurance coverage or a product recall could have a
material adverse effect on the Company's business, financial condition and
results of operations.
 
EMPLOYEES
 
     As of June 30, 1997, the Company had 1,138 full-time employees, including
282 in the United States, 388 in the United Kingdom, 416 in Puerto Rico, 42 in
Canada and 10 in Hungary. Of the Company's full-time employees, 128 are engaged
in sales and marketing, 755 in manufacturing, 173 in distribution, six in
process development and 80 in finance and administration. The Company also
utilizes a number of part-time employees in its manufacturing and distribution
operations to supplement its full-time workforce. The Company's success is
dependent in part on its ability to attract and retain qualified employees. In
particular, the loss of John D. Fruth, the Company's founder and President,
would have a material adverse effect on the Company's development and marketing
efforts. None of the Company's employees is represented by a labor union or is
the subject of a collective bargaining agreement with respect to his or her
employment by the Company. The Company has never experienced a work stoppage and
believes that its employee relations are good. See "Risk Factors -- Dependence
on Key Personnel."

International, L.P., collectively, are entitled to nominate one director of the
Company and Allergan is entitled to nominate one director of the Company,

BOARD COMMITTEES
 
     The Company's Compensation Committee was formed in January 1993 to review
and approve the compensation and benefits for the Company's key executive
officers, administer the Company's stock purchase and stock option plans and
make recommendations to the Board regarding such matters. The Compensation
Committee is currently composed of Edgar J. Cummins, William R. Grant and
Francis R. Tunney, Jr. No interlocking relationship exists between the Board or
Compensation Committee and the board of directors or compensation committee of
any other company, nor has any such interlocking relationship existed in the
past. The Audit Committee was formed in January 1993 to review the internal
accounting procedures of the
 
                                       53
<PAGE>   53
 
Company and to consult with and review the services provided by the Company's
independent auditors. The Audit Committee is currently comprised of Edgar J.
Cummins, William R. Grant and Francis R. Tunney, Jr.
 
DIRECTOR COMPENSATION
 
     Members of the Board do not receive cash compensation for their services as
directors but are reimbursed for their reasonable expenses in attending meetings
of the Board. Historically, the Board members have been issued shares as
compensation for service. In January 1997, William R. Grant, Terence M. Fruth,
Edgar J. Cummins and Francis R. Tunney, Jr. were issued 742, 680, 680 and 186
shares of Common Stock, respectively, as compensation for service during 1996.
 
     In June 1997, the Board adopted and the stockholders approved the 1997
Directors Stock Option Plan (the "Directors Plan") and reserved a total of
300,000 shares of the Company's Common Stock for issuance thereunder. Only
members of the Board who are not employees of the Company, or any parent,
subsidiary or affiliate of the Company, are eligible to participate in the
Directors Plan. On the effective date of the Registration Statement (the
"Effective Date"), each eligible director will automatically be granted an
option to purchase 30,000 shares. Each eligible director who becomes a member of
the Board after the Effective Date will automatically be granted an option to
purchase 30,000 shares upon joining the Board. In addition, each eligible
director will automatically be granted an option to purchase 15,000 shares on
each anniversary date of such director's initial option grant under the
Directors Plan if such director has served continuously as a member of the Board
since the date such director was first granted an option under the Directors
Plan. All options issued under the Directors Plan will vest as to 1/36 per month
commencing one month after the date of grant, for so long as the optionee
continues as a member of the Board or as a consultant to the Company. The
exercise price of all options granted under the Directors Plan will be the fair
market value of the Common Stock on the date of grant.
 
INDEMNIFICATION OF DIRECTORS AND EXECUTIVE OFFICERS AND LIMITATION OF LIABILITY
 
     As permitted by the Delaware General Corporation Law, the Company's
Certificate of Incorporation includes a provision that eliminates the personal
liability of its directors for monetary damages for breach of fiduciary duty as
a director, except for liability (i) for any breach of the director's duty of
loyalty to the corporation or its stockholders, (ii) for acts or omissions not
in good faith or that involve intentional misconduct or a knowing violation of
law, (iii) under Section 174 of the Delaware General Corporation Law (regarding
unlawful dividends and stock purchases) or (iv) for any transaction from which
the director derived an improper personal benefit.
 
     As permitted by the Delaware General Corporation Law, the Bylaws of the
Company provide that (i) the Company is required to indemnify its directors and
officers to the fullest extent permitted by the Delaware General Corporation
Law, subject to certain very limited exceptions, (ii) the Company may indemnify
its other employees and agents as set forth in the Delaware General Corporation
Law, (iii) the Company is required to advance expenses, as incurred, to its
directors and executive officers in connection with a legal proceeding to the
fullest extent permitted by the Delaware General Corporation Law, subject to
certain very limited exceptions, (iv) the rights conferred in the Bylaws are not
exclusive and (v) the Company is authorized to enter into indemnification
agreements with its directors, officers, employees and agents.
 
     The Company has entered into indemnity agreements with each of its current
directors and executive officers to give such directors and executive officers
additional contractual assurances regarding the scope of the indemnification set
forth in the Company's Bylaws and to provide additional procedural protections.
At present, there is no pending litigation or proceeding involving a director,
officer or employee of the Company regarding which indemnification is sought,
nor is the Company aware of any threatened litigation that may result in claims
for indemnification.

     The following table sets forth information regarding option grants during
1996 to each of the Named Executive Officers. In accordance with the rules of
the Securities and Exchange Commission, the table sets forth the hypothetical
gains or "option spreads" that would exist for the options at the end of their

EMPLOYEE BENEFIT PLANS
 
   
     1989 Stock Option Plan. Under the 1989 Plan, as of June 30, 1997 options to
purchase 1,799,694 shares of Common Stock were outstanding and 279,294 shares of
Common Stock were reserved for issuance for options available for grant to
employees, officers, directors, consultants, independent contractors and
advisors. In July 1997, the Company granted options to purchase an aggregate of
18,000 additional shares of Common Stock under the 1989 Plan at an exercise
price of $14.00 per share, including an option to purchase 5,000 shares granted
to Mr. Tunney, a director of the Company and granted options to purchase in
aggregate of 13,000 shares of common stock under the 1989 Plan at an exercise
price equal to the initial public offering of the Common Stock. The 1989 Plan
will be terminated upon the effective date of the Registration Statement for
this offering, when the 1997 Equity Incentive Plan will become effective. As a
result, no further options may be granted under the 1989 Plan following the
closing of this offering. However, termination does not
    
 
                                       54
<PAGE>   56
 
affect any outstanding options, all of which will remain outstanding until
exercised or until they terminate or expire in accordance with their terms. The
terms of options granted under the 1989 Plan and the administration of the plan
are substantially the same as those that pertain to the 1997 Equity Incentive
Plan, except that the vesting of options granted prior to March 1, 1995 under
the 1989 Plan accelerates upon certain acquisitions of the Company unless the
options are assumed or substituted by the acquiring corporation.
 
     1992 Officers and Directors Stock Option Plan. There are options to
purchase 1,280,000 shares of the Company's Common Stock outstanding under the
1992 Plan, all of which have been granted to John D. Fruth. These options were
granted in 1992 at an exercise price of $0.29 per share, are fully vested and
terminate in September 1997. The 1992 Plan will be terminated upon the effective
date of the Registration Statement for this offering, when the 1997 Equity
Incentive Plan will become effective. However, termination does not affect these
outstanding options, which will remain outstanding until exercised or until they
terminate or expire in accordance with their terms. The Company expects that Mr.
Fruth will exercise such options prior to the consummation of this offering.
 
     1997 Equity Incentive Plan. In June 1997, the Board adopted and the
stockholders approved the 1997 Equity Incentive Plan, under which 2,000,000
shares of Common Stock are reserved for issuance. Any authorized shares not
issued or subject to outstanding grants under the 1989 Plan on the effective
date of this offering (279,294 shares as of June 30, 1997) and any shares that
are issuable upon exercise of options granted pursuant to the 1989 Plan that
expire or become unexercisable for any reason without having been exercised in
full will be available for future grant and issuance under the 1997 Equity
Incentive Plan. No options have been issued under the 1997 Equity Incentive
Plan. The 1997 Equity Incentive Plan will become effective on the effective date
of the Registration Statement for this offering and will terminate in May 2007,
unless sooner terminated by the Board. The 1997 Equity Incentive Plan authorizes
the award of options, opportunities to purchase restricted stock and stock
bonuses (each an "Award"). The 1997 Equity Incentive Plan is administered by a
committee appointed by the Board, currently the Compensation Committee,
consisting of Messrs. Cummins, Grant and Tunney, all of whom are "nonemployee
directors" under applicable federal securities laws and "outside directors" as
defined under applicable federal tax laws. The committee has the authority to
construe and interpret the 1997 Equity Incentive Plan and any agreement made
thereunder, grant Awards and establish their terms and make all other
determinations necessary or advisable for the administration of the 1997 Equity
Incentive Plan.
 
     The 1997 Equity Incentive Plan provides for the grant of both incentive
stock options ("ISOs") that qualify under Section 422 of the Internal Revenue
Code of 1986, as amended, and nonqualified stock options ("NQSOs"). ISOs may be
granted only to employees of the Company or of a parent or subsidiary of the
Company. NQSOs may be granted to employees, officers, directors, consultants,
independent contractors and advisors of the Company or of any parent or
subsidiary of the Company, provided such consultants, independent contractors
and advisors render bona fide services not in connection with the offer and sale
of securities in a capital-raising transaction ("Eligible Service Providers").
The exercise price of ISOs must be at least equal to the fair market value of
the Company's Common Stock on the date of grant (110% of that value in the case
of ISOs issued to ten percent stockholders). The exercise price of NQSOs must be
at least equal to 85% of that value. The maximum term of options granted under
the 1997 Equity Incentive Plan is ten years. Options granted under the 1997
Equity Incentive Plan may not be transferred in any manner other than by will or
by the laws of descent and distribution and may be exercised during the lifetime
of the optionee only by the optionee. Options granted under the 1997 Equity
Incentive Plan generally expire 90 days after the termination of the optionee's
service to the Company or to a parent or subsidiary of the Company, except in
the case of death or disability, in which case the options may be exercised up
to 12 months following the date of death or termination of service. Options
terminate immediately upon termination of employment for cause.
 
     Opportunities to purchase shares of the Company's Common Stock and awards
of shares of the Company's Common Stock, either of which may be subject to a
right of repurchase in favor of the Company or other restrictions on ownership
or transfer, may be given to Eligible Service Providers.
 
     In the event of certain acquisitions of the Company, any or all outstanding
Awards may be assumed or replaced by the successor corporation. In the
alternative, the successor corporation may substitute equivalent
 
                                       55
<PAGE>   57
 
Awards or provide consideration to Award recipients which is substantially
similar to that provided to stockholders. If the successor does not assume or
substitute Awards, outstanding Awards will expire upon consummation of the
transaction, provided that the Board in its sole discretion may provide that the
vesting of any or all Awards will accelerate prior to such consummation.
 
     1997 Employee Stock Purchase Plan. In June 1997, the Board adopted and the
stockholders approved the 1997 Employee Stock Purchase Plan (the "Purchase
Plan") and reserved a total of 400,000 shares of the Company's Common Stock for
issuance thereunder. The Purchase Plan will become effective upon the effective
date of the Registration Statement for this offering and will permit eligible
employees to acquire shares of the Company's Common Stock through payroll
deductions. Eligible employees may select a rate of payroll deduction between 2%
and 10% of their compensation and are subject to certain maximum purchase
limitations described in the Purchase Plan. Except for the first offering, each
offering under the Purchase Plan will be for a period of 24 months (the
"Offering Period") and will consist of four six-month purchase periods (each a
"Purchase Period"). The purchase price for the Company's Common Stock purchased
under the Purchase Plan is 85% of the lesser of the fair market value of the
Company's Common Stock on the first day of the applicable Offering Period and
the last day of the applicable Purchase Period. The Board has the authority to
determine the date on which the first Offering Period will begin and the length
of such Offering Period. The Board has the power to change the duration of
Offering Periods and Purchase Periods. The Purchase Plan is intended to qualify
as an "employee stock purchase plan" under Section 423 of the Code.

                              CERTAIN TRANSACTIONS
 
     Since January 1, 1994, there has not been nor is there currently proposed,
any transaction or series of similar transactions to which the Company or any of
its subsidiaries was or is to be a party in which the amount involved exceeds
$60,000 and in which any director, executive officer, holder of more than 5% of
the Common Stock of the Company or any member of the immediate family of any of
the foregoing persons had or will have a direct or indirect material interest
other than (i) compensation agreements, which are described where required in
"Management," and (ii) the transactions described below.
 
OSL ACQUISITION AND RELATED LITIGATION
 
     In September 1992, the Company acquired PLL, a United Kingdom-based
manufacturer of contact lenses and, until the acquisition, a supplier to the
Company, for a total of 1,728,000 shares of the Company's Common Stock (the "PLL
Acquisition"). After the acquisition, PLL was renamed Ocular Sciences Ltd.
("OSL"). The owners of PLL (the "PLL Owners") included John D. Fruth, the
Company's President and a director and principal stockholder of the Company, who
received 496,976 shares of the Company's Common Stock in the acquisition, and
Geoffrey H. Galley and his son Anthony D. Galley (together, the "Galleys"),
principal stockholders of the Company, who received 1,015,024 shares of the
Company's Common Stock in the acquisition.
 
     In connection with the PLL Acquisition, PLL entered into a patent license
agreement with the PLL Owners other than Mr. Fruth (the "Patent Owners"),
pursuant to which PLL obtained a non-exclusive license to certain contact lens
manufacturing patents in exchange for royalty payments that were to aggregate up
to $4.4 million, of which up to $3.6 million was to be paid to the Galleys. An
additional royalty was to be payable by PLL on certain sales by it to other
contact lens manufacturers. Royalties totaling $1.7 million were accrued in
1994, and, as of December 31, 1994, the Company had made cumulative royalty
payments of approximately $3.2 million. No royalty payments were made after 1994
as a result of the lawsuit described below. Also in connection with the PLL
Acquisition, PLL entered into a purchase and supply agreement with Aspect Vision
Care Ltd. ("AVCL"), a United Kingdom-based contact lens distributor controlled
by certain of the Patent Owners, pursuant to which PLL agreed to manufacture and
supply contact lenses to AVCL at a purchase price equal to the Company's direct
and indirect costs of processing the lenses, plus 20% (the "Purchase and Supply
Agreement"). In connection with the Purchase and Supply Agreement, PLL agreed
not to sell the contact lenses covered by such agreement to third parties in the
United Kingdom, and AVCL agreed not to sell such lenses in North and South
America, for a period of ten years (subject to certain exceptions). AVCL
accounted for approximately $1.9 million of the Company's net sales for the year
ended December 31, 1994 and $407,000 of accounts receivable as of December 31,
1995 and 1996. There were no sales to AVCL in 1995 and 1996. See Note 12 of
Notes to Consolidated Financial Statements.
 
     In May 1992, Anthony Galley was appointed Managing Director of PLL and in
November 1992 entered into an employment agreement with PLL. Mr. Galley was also
appointed Vice President, Manufacturing, of the Company. In 1993 and 1994,
disputes arose between the Company, OSL, Anthony Galley and AVCL regarding the
type, price and quantity of contact lenses that OSL was obligated to supply to
AVCL under the Purchase and Supply Agreement. AVCL constructed its own
manufacturing facility in 1994 using information that the Company believed to be
proprietary to OSL.
 
     In April 1994, OSL terminated Anthony Galley's employment, and, in the
following month, the Company and OSL sued AVCL, the Galleys, the other Patent
Owners and certain related persons in the United Kingdom and later in
California. The suit in the United Kingdom alleged misappropriation of
intellectual property, breach of fiduciary duty, breach of contract and other
claims, while the suit in California alleged securities fraud arising out of the
PLL Acquisition. The defendants brought a counterclaim against OSL and the
Company for sums allegedly due under the patent license agreement and breach of
Anthony Galley's employment contract, and other claims, and brought a separate
action in the United Kingdom against OSL alleging patent infringement.
 
     In November 1996, judgment was rendered in the United Kingdom actions. The
judgment found against the Company and OSL on the most important claims brought
by them. In the judgment, the judge harshly
 
                                       60
<PAGE>   59
 
criticized the Company's business practices and stated that he did not believe
the testimony of Messrs. Fruth and Lichtwardt, the Company's Chief Executive
Officer and Chief Financial Officer, respectively. The judge found in favor of
the defendants on a number of their counterclaims, although not on the issue of
patent infringement, which was decided in favor of OSL.
 
     In February 1997, prior to the determination of any costs or damages, the
Company and the other parties to the foregoing litigations entered into a
settlement agreement (the "Settlement Agreement") providing for, among other
things (i) a mutual release among the parties, including a release from any
further amounts owed under the patent license agreement or Purchase and Supply
Agreement, and the termination of all pending litigation, (ii) the replacement
of the patent license agreement with a new, fully paid-up, non-exclusive patent
license that did not limit OSL's ability to sell contact lenses to other contact
lens manufacturers, (iii) the grant by OSL to AVCL and the Patent Owners of a
royalty-free, non-exclusive license to any OSL proprietary information that was
in their possession as of the commencement of the lawsuits in May 1994, (iv) the
termination of the Purchase and Supply Agreement, including the elimination of
the restriction on the Company's ability to sell contact lenses in the United
Kingdom (with the payment of a royalty in certain limited circumstances) and the
elimination of the restriction on AVCL's ability to sell contact lenses in North
and South America, (v) the placement of the Company's shares owned by the Patent
Owners in a voting trust, which trust is to expire upon the effectiveness of
this offering and (vi) certain priority registration rights for the Patent
Owners in connection with public offerings of the Company, including this
offering. The Settlement Agreement also provided for the payment of $10 million
by the Company, of which $3.3 million (net of withholding) was paid on the date
of the Settlement Agreement and the remaining $6.7 million is to be paid upon
the closing of the Company's initial public offering. See Note 14 of Notes to
Consolidated Financial Statements.
 
ALLERGAN/AMERICAN HYDRON ACQUISITION; GALEN FINANCING
 
     In October 1992, the Company acquired the North and South American contact
lens business of Allergan Optical, Inc., which had been operating under the name
American Hydron, for $24.5 million. Allergan Optical, Inc. was a wholly-owned
subsidiary of Allergan, Inc. (together referred to as "Allergan"). The American
Hydron acquisition and related working capital requirements were financed by the
issuance of (i) a senior secured note in the amount of $7.0 million to Allergan,
(ii) senior subordinated notes in the aggregate principal amount of $16.3
million, $13.8 million of which was issued to Allergan and $2.5 million of which
was issued to Galen Partners, L.P. and Galen Partners International L.P.
(together, the "Galen Group"), (iii) 118,168 shares of Series A Preferred Stock
(valued at $8.46 per share, for an aggregate value of approximately $1.0
million) to Allergan, (iv) 3,403,192 shares of Common Stock at $1.47 per share,
for an aggregate price of approximately $5.0 million, to the Galen Group and (v)
warrants to purchase an aggregate of 3,492,688 shares of Common Stock at an
exercise price of $0.00125 per share, 2,957,000 of which were issued to Allergan
and 535,688 of which were issued to the Galen Group. The senior secured note was
repaid from bank borrowings in 1993 and the senior subordinated notes were
repaid from bank borrowings in October 1996. In December 1994, Allergan and the
Galen Group exercised their warrants to purchase 2,467,456 and 356,936 shares of
Common Stock, respectively. Effective December 31, 1996, the remaining warrants
were canceled pursuant to their terms because the Company had met certain
financial milestones.
 
     In connection with the American Hydron acquisition, the Company entered
into a Shareholders' Agreement that provided each of Allergan and the Galen
Group with the right to appoint one person to the Board, which positions are
currently filled by Messrs. Tunney and Grant, respectively. The Shareholders'
Agreement also placed certain restrictions on the ability of the signatories
thereto to transfer their shares. Such rights and restrictions will expire on
consummation of this offering. The Company also entered into a registration
rights agreement providing the Company's then current shareholders, including
John D. Fruth, Allergan, the Galen Group and the Galleys, with certain
registration rights. See "Description of Capital Stock -- Registration Rights."

PAYMENTS TO DIRECTOR
    
 
     Fruth & Anthony, a law firm in which Terence M. Fruth, a director of the
Company and the brother of John D. Fruth, the President of the Company, is a
partner, has provided legal services to the Company since its formation. The
Company made payments of $399,834 in 1994, $309,253 in 1995, $283,945 in 1996
and $58,470 in the first six months of 1997 to Fruth & Anthony for such legal
services.
 
LOANS FROM MR. FRUTH
 
     From July 1986 to March 1990, John D. Fruth loaned the Company a total of
$2.9 million to meet certain short-term operating cash requirements. In October
1992, in connection with the American Hydron acquisition, Mr. Fruth was issued a
junior subordinated promissory note in the principal amount of $2.9 million to
evidence the outstanding principal and interest on such loans (the "Fruth
Note"). The Fruth Note bears interest at the prime rate plus 3%. The Fruth Note
was further subordinated in connection with the Company's borrowings under the
Comerica Credit Agreement in October 1996. In June 1997, the Fruth Note was
amended to provide, among other things, that all principal and unpaid interest
is payable on the earlier of November 1, 1997 or the consummation by the Company
of a public offering in which it receives net proceeds of at least $37.0
million. The Company expects to repay the Fruth Note with a portion of the
proceeds of this offering.

                          DESCRIPTION OF CAPITAL STOCK
 
     Upon the closing of this offering, the authorized capital stock of the
Company will consist of 80,000,000 shares of Common Stock, $0.001 par value, and
4,000,000 shares of Preferred Stock, par value $0.001. As of June 30, 1997, and
assuming the conversion of all outstanding Preferred Stock into Common Stock,
there were outstanding 16,826,326 shares of Common Stock held of record by
approximately 50 stockholders, and options to purchase 3,079,694 shares of
Common Stock.
 
     The following summary of certain provisions of the Common Stock and
Preferred Stock does not purport to be complete and is subject to, and qualified
in its entirety by, the provisions of the Company's Amended and Restated
Certificate of Incorporation, which is included as an exhibit to the
Registration Statement of which this Prospectus forms a part, and by the
provisions of applicable law.
 
COMMON STOCK
 
     Subject to preferences that may be applicable to any Preferred Stock
outstanding at the time, the holders of outstanding shares of Common Stock are
entitled to receive dividends out of assets legally available therefor at such
times and in such amounts as the Board may from time to time determine. Each
stockholder is entitled to one vote for each share of Common Stock held on all
matters submitted to a vote of stockholders. The Common Stock is not entitled to
preemptive rights and is not subject to conversion or redemption. Upon
liquidation, dissolution or winding-up of the Company, the assets legally
available for distribution to stockholders are distributable ratably among the
holders of the Common Stock and any participating Preferred Stock outstanding at
that time after payment of liquidation preferences, if any, on any outstanding
Preferred Stock and payment of other claims of creditors. Each outstanding share
of Common Stock is, and all shares of Common Stock to be outstanding upon
completion of this offering will be, fully paid and nonassessable.
 
PREFERRED STOCK
 
     Upon the closing of this offering, each outstanding share of Preferred
Stock (the "Convertible Preferred") will be converted into two shares of Common
Stock. See Note 9 of Notes to Consolidated Financial Statements for a
description of the Convertible Preferred. Pursuant to the Company's Certificate
of Incorporation, the Board is authorized to provide for the issuance of shares
of Preferred Stock in one or more series, to establish from time to time the
number of shares to be included in each such series, to fix the rights,
preferences and privileges of the shares of each wholly unissued series and any
qualifications, limitations or restrictions thereon, and to increase or decrease
the number of shares of any such series (but not below the number of shares of
such series then outstanding), without any further vote or action by the
stockholders. The Board may authorize the issuance of Preferred Stock with
voting or conversion rights that could adversely affect the voting power or
other rights of the holders of Common Stock. Thus, the issuance of Preferred
Stock may have the effect of delaying, deferring or preventing a change in
control of the Company. The Company has no current plan to issue any shares of
Preferred Stock.
 
REGISTRATION RIGHTS
 
     Following this offering, the holders of approximately 12,323,120 shares of
Common Stock (the "Registrable Securities") will have certain rights to register
those shares under the Securities Act. The holders of Registrable Securities
have agreed that they will not exercise any right with respect to any such
registrations for a period ending 180 days after the effective date of the
Registration Statement for this offering without the prior written consent of
Morgan Stanley & Co. Incorporated. Thereafter, if requested by the holders of at
least 10% of the Registrable Securities, the Company must file a registration

offering represents at least 20% of the Registrable Securities then outstanding.
These rights are subject to certain conditions and limitations, among them the
right of the underwriters of an offering to limit the number of shares included
in such registration in certain circumstances. The Company may be required to
effect up to three such registrations, plus one additional such registration for
each registration that does not include all holders' Registrable Securities
requested to be included. All expenses incurred in connection with such
registrations (other than underwriters' discounts and commissions) will be borne
by the Company. These demand registration rights expire October 30, 2002.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
     In addition to the 7,200,000 shares of Common Stock offered hereby
(assuming no exercise of the Underwriters' overallotment option), as of the
effective date of the Registration Statement of which this Prospectus forms a
part (the "Effective Date"), there will be 13,226,326 shares of Common Stock
outstanding, all of which are "restricted" shares (the "Restricted Shares")
under the Securities Act. Of the Restricted Shares, an aggregate of 13,222,166
shares of Common Stock will be eligible for sale in the public market subject to
Rule 144 and Rule 701 under the Securities Act after expiration of a contractual
lock-up beginning 180 days after the date of the Prospectus, unless earlier
released, in whole or in part, by Morgan Stanley & Co. Incorporated. Of these
shares, an aggregate of 12,148,704 shares are held by "affiliates" of the
Company and accordingly will be subject to certain volume and resale
restrictions set forth in Rule 144. In addition, an aggregate of 2,660 shares of
Common Stock will become eligible for resale in the public market upon
expiration of a one-year holding period, subject to certain volume and resale
restrictions set forth in Rule 144, in the first quarter of 1998. Sales of a
substantial number of Restricted Shares in the public market following this
offering could adversely affect the market price of the Common Stock and the
ability of the Company to raise equity capital in the future.
 
     In general, under Rule 144 as currently in effect, beginning 90 days after
the date of this Prospectus, a person (or persons whose shares are aggregated)
who has beneficially owned Restricted Shares for at least one year (including
the holding period of any prior owner except an affiliate of the Company) would
be entitled to sell within any three-month period a number of shares that does
not exceed the greater of (i) 1% of the number of shares of Common Stock then
outstanding (which will equal approximately 204,263 shares immediately after
this offering) or (ii) the average weekly trading volume of the Common Stock on
the Nasdaq National Market during the four calendar weeks preceding the filing
of a notice on Form 144 with respect to such sale. Sales under Rule 144 are also
subject to certain manner of sale provisions and notice requirements and to the
availability of current public information about the Company. Under Rule 144(k),
a person who is not deemed to have been an affiliate of the Company at any time
during the 90 days preceding a sale, and who has beneficially owned the shares
proposed to be sold for at least two years (including the holding period of any
prior owner except an affiliate of the Company), is entitled to sell such shares
without complying with the manner of sale, public information, volume limitation
or notice provisions of Rule 144. Unless otherwise restricted, "144(k) shares"
may therefore be sold immediately upon the completion of this offering.
 
     Rule 701 permits resales of shares in reliance upon Rule 144, but without
compliance with certain restrictions, including the holding period requirement,
of Rule 144. Any employee, officer or director of, or consultant to, the Company
who purchased his or her shares pursuant to a written compensatory plan or
contract may be entitled to rely on the resale provisions of Rule 701. The
Securities and Exchange Commission has indicated that Rule 701 will apply to
typical stock options granted by an issuer before it becomes subject to the
reporting requirements of the Securities Exchange Act of 1934, as amended, along
with the shares acquired upon exercise of such options (including exercises
after the date of this Prospectus). Rule 701 permits affiliates to sell their
Rule 701 shares under Rule 144 without complying with the holding period
requirements of Rule 144. Rule 701 further provides that non-affiliates may sell
such shares in reliance on Rule 144 without having to comply with the holding
period, public information, volume limitation or notice provisions of Rule 144.
In both cases, a holder of Rule 701 shares is required to wait until 90 days
after the date of this Prospectus before selling such shares.
 
     Immediately after this offering, the Company intends to file a registration
statement under the Securities Act covering 5,658,988 shares of Common Stock
reserved for issuance under the Company's stock option plans. Shares of Common
Stock issued upon exercise of options under the Form S-8 will be available for
sale in the public market, subject to Rule 144 volume limitations applicable to
affiliates and subject to lock-up agreements. At June 30, 1997, options to
purchase 3,079,694 shares of Common Stock were outstanding. Beginning 180 days
after the Effective Date, shares issuable upon the exercise of vested options
will be eligible for sale, if such options are exercised. See
"Management -- Director Compensation" and "Management -- Employee Benefit
Plans."

     The Underwriting Agreement provides that the obligations of the several
Underwriters to pay for and accept delivery of the shares of Common Stock
offered hereby are subject to the approval of certain legal matters by their
counsel and to certain other conditions. The Underwriters are obligated to take
and pay for all the shares of Common Stock offered hereby (other than the shares
covered by the overallotment option described below) if any such shares are
taken.
 
     The Underwriters propose to offer part of the shares of Common Stock
directly to the public at the public offering price set forth on the cover page
hereof and part to certain dealers at a price which represents a concession not
in excess of $          per share under the initial public offering price. The
Underwriters may allow, and such dealers may re-allow, a concession not in
excess of $          per share to other Underwriters or to certain other
dealers. After the initial offering of the Common Stock, the offering price and
other selling terms may from time to time be varied by the Representatives.
 
     Pursuant to the Underwriting Agreement, certain of the Selling Stockholders
have granted to the Underwriters an option, exercisable for 30 days from the
date of this Prospectus, to purchase up to 1,080,000 additional shares of Common
Stock at the initial public offering price set forth on the cover page hereof,
less underwriting discounts and commissions. The Underwriters may exercise such
option solely for the purpose of covering overallotments, if any, incurred in
the sale of the shares of Common Stock offered hereby. To the extent such option
is exercised, each Underwriter will become obligated, subject to certain
conditions, to purchase approximately the same percentage of such additional
shares as the number set forth next to such Underwriter's name in the preceding
table bears to the total number of shares of Common Stock offered hereby to the
Underwriters.
 
     The Representatives have informed the Company that the Underwriters do not
intend to confirm sales in excess of five percent of the number of shares of
Common Stock offered hereby to accounts over which they exercise discretionary
authority.
 
     The Company, the Selling Stockholders and the Underwriters have agreed to
indemnify each other against certain liabilities, including liabilities under
the Securities Act.
 
     See "Shares Eligible for Future Sale" for a description of certain
arrangements by which all officers, directors, stockholders and option holders
of the Company have agreed not to sell or otherwise dispose of Common Stock or
convertible securities of the Company for up to 180 days after the date of this
Prospectus without the prior consent of Morgan Stanley & Co. Incorporated. The
Company has agreed in the Underwriting Agreement that it will not, directly or
indirectly, without the prior written consent of Morgan Stanley & Co.
Incorporated, contract to sell, sell any option or contract to purchase,
purchase any option or contract to sell, grant any option, right or warrant to
purchase, or otherwise transfer or dispose of any shares of Common Stock or any
securities convertible into or exchangeable for Common Stock, for a period of
180 days after the date of this Prospectus, except under certain circumstances.
 
     In order to facilitate the offering of the Common Stock, the Underwriters
may engage in transactions that stabilize, maintain or otherwise affect the
price of the Common Stock. Specifically, the Underwriters may
 
                                       68
<PAGE>   67
 
overallot in connection with the offering, creating a short position in the
Common Stock for their own account. In addition, to cover overallotments or to
stabilize the price of the Common Stock, the Underwriters may bid for, and
purchase, shares of Common Stock in the open market. Finally, the underwriting
syndicate may reclaim selling concessions allowed to an underwriter or a dealer
for distributing the Common Stock in the offering, if the syndicate repurchases
previously distributed Common Stock in transactions to cover syndicate short
positions, in stabilization transactions or otherwise. Any of these activities
may stabilize or maintain the market price of the Common Stock above independent
market levels. The Underwriters are not required to engage in these activities
and may end any of these activities at any time.
 
     The Underwriters have reserved for sale, at the initial public offering
price, up to five percent of the Common Stock offered hereby for employees and
directors of the Company and certain others who have expressed an interest in
purchasing such shares of Common Stock in the offering. The number of shares
available for sale to the general public will be reduced to the extent such
persons purchase such reserved shares. Any reserved shares not so purchased will
be offered by the Underwriters to the general public on the same basis as other
shares offered hereby.
 
PRICING OF THE OFFERING
 
     Prior to this offering, there has been no public market for the Common
Stock of the Company. The initial public offering price for the Common Stock
will be determined by negotiations among the Company, the Selling Stockholders
and the Representatives. Among the factors to be considered in determining the
initial public offering price will be the future prospects of the Company and
its industry in general, sales, earnings and certain other financial and
operating information of the Company in recent periods, and the price-earnings
ratios, price-sales ratios, market prices of securities and certain financial
and operating information of companies engaged in activities similar to those of
the Company. The estimated initial public offering price range set forth on the
cover page of this Preliminary Prospectus is subject to change as a result of
market conditions and other factors.
 
                                 LEGAL MATTERS
 
     The validity of the shares of Common Stock offered hereby will be passed
upon for the Company by Fenwick & West LLP, Palo Alto, California. Certain legal
matters will be passed upon for the Underwriters by Gunderson Dettmer Stough
Villeneuve Franklin & Hachigian, LLP, Menlo Park, California.

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors
Ocular Sciences, Inc.
 
     We have audited the accompanying consolidated balance sheets of Ocular
Sciences, Inc. and subsidiaries as of December 31, 1995 and 1996, and the
related consolidated statements of income, stockholders' equity and cash flows
for each of the years in the three-year period ended December 31, 1996. These
consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
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 consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Ocular
Sciences, Inc. and subsidiaries as of December 31, 1995 and 1996, and the
results of their operations and their cash flows for each of the years in the
three-year period ended December 31, 1996, in conformity with generally accepted
accounting principles.

NOTE 1. NATURE OF BUSINESS
 
FORMATION AND BUSINESS OF THE COMPANY
 
     O.S.I. Corporation was incorporated in California in 1985. The Company is
engaged in the design, manufacture and distribution of contact lenses and
conducts business under the name of Ocular Sciences/American Hydron.
 
     On May 12, 1997, the Company's Board of Directors approved a
reincorporation into the state of Delaware. The Board of Directors also approved
a change in the Company's name to Ocular Sciences, Inc. (the "Company") and
authorized the filing of a registration statement with the Securities and
Exchange Commission permitting the Company to sell shares of its common stock in
a proposed initial public offering. In connection with the reincorporation, the
stockholders of the Company approved a two-for-one stock split and increased its
authorized common stock to 80,000,000. All applicable share and per share
amounts in the accompanying consolidated financial statements have been
retroactively adjusted to reflect the reincorporation and the stock split.
 
NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Basis of Consolidation
 
     The accompanying consolidated financial statements include the accounts of
the Company and its wholly-owned subsidiaries, Ocular Sciences Ltd. ("OSL")
(formerly Precision Lens Laboratories Ltd.), O.S.I. Puerto Rico Corporation,
O.S.I. Canada Corporation and Ocular Sciences Hungary. All significant
intercompany balances and transactions have been eliminated in consolidation.
 
  Accounting Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles ("GAAP") requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the reported
period.
 
  Cash and Cash Equivalents
 
     The Company considers all highly liquid cash investments, primarily
consisting of money market funds, with an original maturity of three months or
less to be cash equivalents.
 
  Restricted Cash
 
     Restricted cash consists of cash held in an escrow account for payment of
various commitments of the Company's United Kingdom subsidiary. The largest
component of restricted cash as of December 31, 1995 and 1996 related to
royalties due under a molding patent license for which the Company was in
litigation with the patent owners. The royalties related to liabilities that
were recorded and charged to expense in 1994 and 1995. The Company settled the
litigation with the patent holders in February 1997 (see Notes 12 and 14). The
restricted cash balance as of June 30, 1997 related to cash held in escrow for
the construction and rent of the Company's United Kingdom facility.

                  (INFORMATION SUBSEQUENT TO DECEMBER 31, 1996
            AND FOR THE SIX MONTHS ENDED JUNE 30, 1997 IS UNAUDITED)
 
  Inventories
 
     Inventories are recorded at the lower of cost (first-in, first-out method)
or market. Cost includes material, labor and applicable factory overhead.
Provision for potentially obsolete or slow moving inventory is made based upon
management's analysis of inventory levels and forecasted sales.
 
  Revenue Recognition
 
     The Company recognizes sales upon shipment of products to its customers.
Allowances for sales returns are accrued at the time sales are recognized.
 
  Cooperative Merchandise Allowances
 
     The Company offers a cooperative merchandise program to certain of its
customers whereby the Company reimburses these customers for items such as
advertising, displays and mailings that are intended to encourage the fitting
and wearing of the Company's disposable lenses. The Company records the
provisions for cooperative merchandising at the time of sale to the customers
and as a component of selling and marketing expense.
 
  Foreign Currencies
 
     During the quarter ended December 31, 1994, the functional currencies of
the Company's United Kingdom and Canadian subsidiaries were changed from the
U.S. dollar to the respective local currencies, reflecting the fact that the
local currencies are the currencies in which the subsidiaries primarily generate
and expend cash.
 
     As a result of this change, the subsidiaries translate all asset and
liability accounts at current exchange rates in effect at the balance sheet date
and statement of income accounts at average exchange rates during the period.
Translation adjustments arising from differences in exchange rates from period
to period are included in the financial statements as a separate component of
stockholders' equity.
 
  Concentration of Credit Risk
 
     The Company sells its products to a diverse group of ophthalmologists,
optometrists, optical retailers and optical product distributors, and therefore
the concentration of credit risk with respect to receivables is limited due to
the large number and diversity of customers across broad geographic areas.
Accounts receivable from customers are uncollateralized. As of December 31,
1995, approximately 11% of accounts receivable and 8% of consolidated net sales
were concentrated in one customer, while, as of December 31, 1996, approximately
22% of accounts receivable and 12% of consolidated net sales were concentrated
in two customers and, as of June 30, 1997, approximately 14% of accounts
receivable and 8% of consolidated net sales were concentrated in one customer.
To reduce credit risk, the Company performs ongoing credit evaluations of its
significant customers' respective financial conditions. The Company establishes
an allowance for doubtful accounts based upon factors surrounding the credit
risk of specific customers, historical trends and other information.
 
  Property and Equipment
 
     Property and equipment are recorded at cost and are depreciated using the
straight-line method over the respective estimated useful lives of the assets,
which range from three to ten years. Leasehold improvements are amortized over
the shorter of the respective lease terms or the respective estimated useful
lives of the assets.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
                  (INFORMATION SUBSEQUENT TO DECEMBER 31, 1996
            AND FOR THE SIX MONTHS ENDED JUNE 30, 1997 IS UNAUDITED)
 
  Long-Lived Assets, Including Intangible Assets
 
     The Company adopted Statement of Financial Accounting Standards ("SFAS")
No. 121, "Accounting for Impairment of Long-Lived Assets and for Long-Lived
Assets to be Disposed of," as of January 1, 1996. SFAS No. 121 requires that
long-lived assets and certain identifiable intangibles be reviewed for
impairment whenever events or changes in circumstances indicate that the
carrying amount of assets may not be recoverable. Recoverability of assets to be
held and used is measured by a comparison of the carrying amount of an asset to
future net cash flows expected to be generated by the asset. If such assets are
considered to be impaired, the impairment to be recognized is measured by the
amount by which the carrying amount of the assets exceeds the fair value of the
assets. Assets to be disposed of are reported at the lower of the carrying
amount or fair value less costs to sell. Adoption of SFAS No. 121 did not have
an impact on the Company's consolidated financial position, results of
operations or liquidity.
 
     Marketing rights, trademarks, licenses, and covenants not to compete are
carried at cost less accumulated amortization, which is calculated on a
straight-line basis over the estimated useful lives of the respective assets,
which are typically five to ten years. Goodwill, which represents the excess of
purchase price over fair value of the tangible and intangible assets acquired,
is amortized on a straight-line basis over five years.
 
  Income Taxes
 
     The Company accounts for income taxes in accordance with SFAS No. 109,
"Accounting for Income Taxes." Under SFAS No. 109, deferred income taxes are
recognized for tax consequences in future years of differences between the tax
bases of assets and liabilities and their financial reporting amounts at each
balance sheet date based on enacted tax laws and statutory tax rates expected to
apply in the periods in which the differences are expected to affect taxable
income.
 
     The provision for income taxes has been determined using the asset and
liability approach of accounting for income taxes. Under this approach, deferred
income taxes reflect the tax consequences on future years of temporary
differences between the tax bases of assets and liabilities and their financial
reporting amounts. Provision has been made for income taxes on unremitted
earnings of subsidiaries, except in cases in which earnings of foreign
subsidiaries are deemed to be permanently invested.
 
  Stock-Based Compensation
 
     The Company has adopted the provisions of SFAS No. 123, "Accounting for
Stock-Based Compensation," and has elected to continue to account for
stock-based compensation using methods prescribed in Accounting Principles Board
Opinion ("APB") No. 25, "Accounting for Stock Issued to Employees," and related
Interpretations.
 
     The Company follows the practice of recording amounts received upon the
exercise of options by crediting common stock and additional paid-in capital.
The Company realizes an income tax benefit from the exercise and early
disposition of certain stock options and the exercise of other stock options.
The benefit results in a decrease in current income taxes payable and an
increase in common stock.
 
  Reclassifications
 
     Certain reclassifications were made to the 1994 and 1995 consolidated
financial statements to conform to the 1996 presentation.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
                  (INFORMATION SUBSEQUENT TO DECEMBER 31, 1996
            AND FOR THE SIX MONTHS ENDED JUNE 30, 1997 IS UNAUDITED)
 
  Unaudited Interim Consolidated Financial Information
 
     The unaudited interim consolidated financial information as of June 30,
1997 and for the three months ended June 30, 1996 and 1997 has been prepared on
the same basis as the audited consolidated financial statements. In the opinion
of management, such unaudited information includes all adjustments (consisting
only of normal recurring accruals) necessary for a fair presentation of this
interim information. Operating results for the six months ended June 30, 1997
are not necessarily indicative of the results that may be expected for the
entire year ending December 31, 1997.
 
  Unaudited Pro Forma Stockholders' Equity
 
     The unaudited pro forma stockholders' equity section assumes the conversion
of all outstanding shares of Series A preferred stock into 236,336 shares of the
Company's common stock upon the closing of the Company's anticipated initial
public offering.
 
  Pro Forma Net Income Per Share
 
     Pro forma net income per share is computed based on the weighted average
number of common shares and common equivalent shares outstanding during the
period. Common equivalent shares include convertible preferred shares and the
conversion of stock options using the treasury stock method. The conversion of
the shares of Series A Preferred Stock into 236,336 shares of common stock is
included in the pro forma computation for all periods presented. In accordance
with Securities and Exchange Commission Staff Accounting Bulletins and staff
policy, pro forma net income per share includes all common and common equivalent
shares granted or issued within 12 months of the offering date as if they were
outstanding for all periods presented, even if antidilutive, using the treasury
stock method and the anticipated initial public offering price. Historical net
income per share has not been presented since such amounts are not deemed
meaningful due to the change in the Company's capital structure that will occur
in connection with the Company's anticipated initial public offering.
 
  Supplementary Net Income Per Share
 
     Supplementary net income per share is computed as if the June 30, 1997 debt
balances outstanding of $13,501,000 under the Company's Credit Agreement and
$2,895,000 under a long-term subordinated note payable due to a stockholder had
been paid at the beginning of the period or the date of issuance, if later,
resulting in the elimination of $2,741,000 and $865,000 in interest expense for
the year ended December 31, 1996 and the six months ended June 30, 1997,
respectively.
 
  New Accounting Standard
 
     In February 1997, the Financial Accounting Standards Board issued SFAS No.
128, "Earnings per Share," which will be effective for financial statements for
periods ending after December 15, 1997, including interim periods, and
establishes standards for computing and presenting earnings per share. Earlier
application is not permitted. In its consolidated financial statements for the
year ending December 31, 1997, the Company will make the required disclosures of
basic and diluted earnings per share and provide a reconciliation of the
numerator and denominator of its basic and diluted earnings per share
computations. All prior period earnings per share data will be restated by the
Company upon adoption of SFAS 128. The Company expects that basic earnings per
share of the Company will be greater than primary earnings per share and diluted
earnings per share will be substantially similar to the pro forma net income per
share disclosed herein.

     On October 30, 1996, the Company executed a commercial lending facility
(the "Agreement") with a major commercial bank. The Agreement provides for a
term loan and a revolving line of credit, the proceeds of which were used to
retire the Company's pre-existing line of credit.
 
     The revolving line of credit is available up to the lesser of $17,000,000
or 80% of the Company's eligible accounts receivable plus 50% of the Company's
net inventory, inclusive of an amount of up to $3,000,000 for letters of credit.
The outstanding balance of this line of credit is due in full on October 31,
1999. However, the Company may elect to prepay the principal due under the
revolving line of credit, or the term loan, for a 2% fee on the prepayment
amount if prepaid by October 31, 1997 or a 1% fee thereafter, provided that only
the prepayments under the line of credit may be reborrowed.
 
     The term loan in the amount of $10,000,000 is payable in eight quarterly
installments beginning January 31, 1997, $1,000,000 each quarter in 1997 and
$1,500,000 each quarter in 1998. In addition to the foregoing payments, the term
loan must be repaid with cash proceeds, if applicable, from the Company's sale
of its assets, issuance of its equity (less all placement fees and underwriting
expenses) or subordinated debt, and other extraordinary receipts from litigation
settlement, key man life insurance or tax refunds.
 
     The Agreement provides the Company with two interest rate
options -- interest at 0.25% to 0.75% above the bank's base rate or at 2.25% to
2.75% above the rate at which deposits in eurodollars are offered to the bank by
other prime banks in the eurodollar market, with the percentages varying based
on certain leverage ratios. The effective interest rates on the Agreement as of
December 31, 1996 and June 30, 1997 were 8.125% and 8.1875%, respectively. The
Company pays commitment fees of 0.375% on the unused amount of the revolving
line of credit. There are no commitment fees on the term loan. As of December
31, 1996 and June 30, 1997, the uncommitted line of credit under the Agreement
was $9,400,000 and $11,400,000, respectively, with no amounts outstanding under
the letters of credit. The Agreement is secured by the Company's accounts
receivable, inventory, equipment, loans and notes receivable, and general
intangibles provided that the collateral must not include more than 65% of any
class of equity securities of any foreign

subsidiary. The Company is also required under the Agreement to maintain minimum
debt to tangible net worth, interest coverage and tangible net worth ratios, and
the Agreement places certain limitations on debt, liens, contingent obligations,
investments and cash dividends on common stock. The Company was in compliance
with all covenants associated with the Agreement as of December 31, 1996 and
June 30, 1997.
 
     In late 1995, the Company entered into a bank line of credit under which up
to $3,500,000 was available for borrowings through September 30, 1996. The
Company's accounts receivable, inventory and equipment located in the United
States were pledged as collateral under the agreement. The interest rate for
this facility was fixed at the bank's reference rate plus 0.75% (9.25% at
December 31, 1995). The agreement contained a commitment fee of 0.5% per annum
on the unused portion of the line of credit and also contained restrictive
financial covenants that required maintenance of certain financial ratios and
limited the total amount of fixed or capital purchases. As of December 31, 1995,
no amounts were outstanding on this credit line, which was terminated on October
30, 1996.
 
     The Company has guaranteed the borrowings of its Puerto Rican subsidiary
under a loan agreement with Banco Bilbao Vizcaya Puerto Rico ("BBV") for the
financing of the construction of an industrial building at Santa Isabel
Industrial Park, Santa Isabel, Puerto Rico, and for purchase of machinery and
equipment not to exceed the total sum of $5,800,000. The loan is secured by a
chattel mortgage upon all machinery and equipment purchased with any part of the
loan proceeds and for the full amount of the loan plus interest and other sums
due to the bank. The principal amount of this loan is payable in December 1997
or upon the closing of a permanent financing loan from the Government
Development Bank of Puerto Rico ("GDB"). The Company has secured the commitment
for permanent financing. The BBV loan bears interest at 2% over the lender's
defined cost of funds or, in the event that such funds are not available, 1.5%
over the lender's prime lending rate. The effective interest rates as of
December 31, 1995 and 1996 and June 30, 1997 were 10%, 8% and 9%, respectively.
The BBV loan agreement also contains a commission fee equal to 1% of the
principal and drawing fees equal to 0.5% of the loan amount. As of December 31,
1995 and 1996 and June 30, 1997, the loan amount outstanding on this agreement
was $834,000, $1,069,000 and $1,973,000, respectively.
 
     The long-term debt, including current portion, is due in aggregate annual
installments of $4,273,000, $6,257,000, $7,974,000, $381,000 and $960,000 in
each of the years from 1997 through 2001 and thereafter.

respectively.
 
NOTE 8. STOCK SPLIT
 
     On February 21, 1995, the stockholders of the Company approved a
four-for-one split of the Company's common and preferred stock.
 
NOTE 9. PREFERRED STOCK AND ACCRUED DIVIDENDS
 
     Each share of preferred stock is convertible into two shares of common
stock, at the option of the holder, at any time, on a two-for-one basis, subject
to adjustment for dilution. Each share of preferred stock will automatically
convert into two shares of common stock in the event of (1) the closing of an
underwritten public offering, a sale of substantially all of the assets of the
Company, or a consolidation or merger of the Company in which the stockholders
prior to the event do not represent a majority of the outstanding shares after
the event or (2) upon the written consent of a majority of the total number of
outstanding shares of Series A preferred stock. The shares of preferred stock
may be redeemed, at the Company's election, at a redemption price of 110% of
their original purchase price plus accrued dividends.
 
     Except as required by law, the Series A preferred stock is non-voting. When
Series A preferred stock is entitled to vote as a matter of law, the shares of
Series A preferred stock will have a number of votes equal to the number of
shares of common stock into which they could then be converted.
 
     The holders of Series A preferred stock are entitled to cumulative annual
dividends of 8.25% per annum, prior and in preference to the payment of any
dividends on the common stock (other than a common stock dividend). Such
dividends are cumulative from November 1, 1992 and accrue day to day until paid,
whether or not earned or declared. The cumulative dividends are to be paid by
the Company in cash, in quarterly installments in arrears on April 30, July 31,
October 31 and January 31 of each year ("payment dates"). Cumulative dividends
of $14,000 were outstanding as of December 31, 1995, 1996 and as of June 30,
1997 and are included in accrued liabilities. Holders of Series A preferred
stock, as their sole and exclusive remedy, may elect, at their option upon
written notice to the Company, to receive shares of common stock in lieu of cash
dividends accrued if the Company fails to pay accrued dividends for eight
consecutive payment dates. Cumulative dividends accrued through October 31, 1994
were paid to holders of Series A preferred stock in January 1995 and scheduled
quarterly dividend payments were made thereafter.
 
     In the event of liquidation, holders of Series A preferred stock are
entitled to receive an amount equal to the original purchase price of their
shares of preferred stock plus all accrued and unpaid dividends.
 
NOTE 10. COMMON STOCK
 
  Warrants
 
     As of December 31, 1995, warrants were outstanding that entitled the
warrant holders to purchase up to 588,296 shares of common stock for $0.00125
per share, subject to adjustment for dilution. The warrants expire on the
earlier of October 30, 2002 or the date of effectiveness of a registration
statement covering at least 35% of the common stock then outstanding. The number
of shares subject to the warrants are reduced if the Company meets certain
financial performance goals and the Company prepays the subordinated notes
payable to stockholders prior to October 30, 1996. The Company repaid this note
on October 30, 1996 (see Note 6 and 12). The warrants were issued on October 30,
1992 in connection with the acquisition of the contact lens business in North
and South America of Allergan, Inc. In accordance with the original terms of

  Stock Option Plans
 
     The Company has two stock-based compensation plans that are described
below. In 1996, the Company adopted the provisions of SFAS No. 123 and elected
to continue to account for stock-based compensation using the methods prescribed
in APB No. 25. Accordingly, no compensation expense has been recognized for its
fixed stock option plans in 1994, 1995 and 1996. Had compensation expense for
the stock option plans been determined consistent with SFAS No. 123, the
Company's net income and net income per share would have been reduced to the pro
forma amounts indicated below:

     The initial effect of applying the SFAS No. 123 disclosure requirement may
not be representative of the effects on reported net income for future years.
The Company's 1989 stock option plan provides for the grant to employees,
directors or consultants of incentive stock options, exercisable at a price not
less than the fair market value of the shares on the grant date, or for
nonqualified options, exercisable at a price not less than 85% of the fair
market value of the shares on the grant date. The options generally are granted
for a six year term and vest over a five-year period. During 1994, the
stockholders approved an amendment to the Company's incentive stock option plan
increasing the number of shares reserved for issuance under that plan by 938,064
to 2,938,064. The fair value of each option grant is estimated on the grant date
by calculating the difference between the current market value of the Company's
common stock and the present value of the exercise price using a risk-free
interest rate of 6.65% over the expected life of five years. The Company
calculated the fair value of options using the minimum value method, which
applies a dividend rate and expected volatility of zero. The per share weighted
average fair value of options granted during the years ended December 31, 1994,
1995, 1996 and six months ended June 30, 1997 were $0.4066, $0.8114, $1.6413 and
$2.2817, respectively.

NOTE 11. INCOME TAXES
 
     Deferred taxes are provided, where warranted, to reflect the future tax
consequences of differences between the financial reporting and tax reporting of
various assets and liabilities; these differences will be either taxable or
deductible when the related assets and liabilities are recovered or settled. The
income tax benefits related to the exercise of stock options reduces taxes
currently payable and is credited to common stock. Such amounts approximated
$273,000 for 1996.

indefinitely. Applicable foreign income taxes have been provided. Although, it
is not practical to estimate the amount of additional tax that might be payable
on the foreign unremitted earnings, credits for foreign income taxes paid will
be available, at tax rates substantially equal to any U.S. tax liability. For
financial reporting purposes, a valuation allowance was recognized as of
December 31, 1994, to reflect the uncertainty of generating taxable income
sufficient to utilize the gross deferred tax asset.
 
NOTE 12. RELATED PARTY TRANSACTIONS
 
   
     On September 30, 1992, the Company entered into a non-exclusive patent
license agreement, which granted the Company the right to manufacture, use and
sell products and processes covered by patents and patent applications owned by
certain former stockholders of OSL, some of whom are stockholders of the
Company. The term of the patent license agreement was the life of the licensed
patents (up to 17 years). The agreement required the Company to pay royalties to
the former OSL stockholders of $0.50 per lens, with a minimum $1,000,000 per
royalty year (from July 1 to June 30) commencing in 1993, until $4,400,000 in
total royalties has been paid on a cumulative basis. Royalty payments totaling
$1,650,000 were made in 1994, and as of December 31, 1994, the Company made
cumulative royalty payments of approximately $3,200,000. Royalty payments of
$1,200,000 were deposited into an escrow account pending settlement of
litigation against certain stockholders of the Company (see Note 14).

     Also, on September 30, 1992, the Company entered into a purchase and supply
agreement with Aspect Vision Care Ltd. ("AVCL"), an entity affiliated with
certain stockholders of the Company. The agreement provided that the Company
would sell lenses to AVCL at a purchase price equal to the Company's direct and
indirect costs of processing the lenses, plus 20%. As discussed in Note 14, AVCL
and the Company were involved in litigation which was settled in February 1997.
AVCL accounted for net sales of approximately $1,863,000 for the year ended
December 31, 1994 and $407,000 of accounts receivable as of December 31, 1995
and 1996. There were no sales to AVCL in 1995 or 1996. A provision was recorded
for the full amount of the accounts receivable from AVCL as of December 31,
1995, which was subsequently written off during the three months ended March 31,
1997.
 
     During 1993 and 1994 certain individuals who held a controlling interest in
AVCL also served as members of the board of directors of the Company's United
Kingdom subsidiary (OSL).
 
     On September 30, 1992, the Company entered into consulting agreements with
two stockholders that called for an aggregate of approximately $7,000 per month
to be paid for consulting services rendered. These agreements were terminated in
February 1997 (see Note 14).
 
     As of December 31, 1995, the Company had approximately $16,042,000 in
subordinated notes, net of debt discount, of which $2,868,000 represented the
current portion. The Company also had accrued interest of $481,000 due to the
Company's warrant holders and certain stockholders. This debt agreement
contained certain restrictive financial covenants requiring the Company to
maintain certain levels of tangible net worth and cash, to maintain specified
ratios (debt to net worth and quick ratio) and to achieve certain levels of
interest expense coverage. The debt was retired on October 30, 1996 (see Note
6).
 
     As of December 31, 1995 and 1996 and June 30, 1997, the Company had a
$2,895,000 long-term junior subordinated note payable due to the Company's
president bearing interest at prime plus 3% (11.5%, 11.25% and 11.25% as of
December 31, 1995, December 31, 1996 and June 30, 1997, respectively). An
agreement was signed by the president on October 30, 1996 that provided for
subordination of this junior subordinated note to debt outstanding to a major
commercial bank (see Note 6). This note was amended on June 1, 1997 whereby
provisions of the subordination was removed and all principal and unpaid
interest is payable to him on November 1, 1997. The president had advanced the
Company funds periodically, prior to 1993, to meet certain short-term operating
cash requirements. Accrued interest on this debt totaled $56,000 as of December
31, 1995 and $54,000 as of December 31, 1996 and June 30, 1997. The president
has the right to exercise stock options held by reducing the principal balance
owed on the note payable in lieu of providing cash payments upon exercise. The
president holds options to purchase 1,280,000 shares of common stock with an
exercise price of $0.29365 per share, subject to adjustment.
 
     A director of the Company, who is also the brother of the President, is a
partner in a law firm which has provided legal services to the Company since its
formation. The Company made payments for legal services of $400,000, $309,000
$284,000 and $93,000 and $59,000 in the years ended December 31, 1994, 1995 and
1996 and the six months ended June 30, 1996 and 1997.

NOTE 14. LITIGATION
 
     In 1994, litigation was commenced by the Company and OSL, its United
Kingdom subsidiary, against former employees and a former director of OSL, its
United Kingdom distributor (AVCL) and certain related parties. The claims by the
Company were essentially for misappropriation of intellectual property, breach
of contract and nonpayment of accounts. In a related matter, there was also a
patent infringement action against OSL which involved the validity of a certain
molding patent that was licensed by OSL from certain of the
 
                                      F-20

defendants. The Company also brought an action in federal court in California
against certain of the same individuals who were sued in the United Kingdom. The
California action was essentially one for breach of employment, breach of
contract and violation of securities laws.
 
     In November 1996, judgment was rendered in the United Kingdom actions. In
February 1997, prior to the determination of any costs or damages by the United
Kingdom courts, the parties to the above litigations entered into a settlement
agreement for total monetary consideration of $10,000,000. The settlement
agreement provided for, among other things, (i) a mutual release and termination
of all pending litigation; (ii) the replacement of the September 30, 1992 patent
license agreement (See Note 12) with a new, fully paid-up, non-exclusive, patent
license, that did not contain any restrictions on the Company's ability to sell
contact lenses to other contact lens manufacturers; and, (iii) the termination
of the Company's obligation to supply contact lenses under the September 30,
1992 purchase and supply agreement (See Note 12), including a limitation of the
Company to sell contact lenses directly into the United Kingdom. The Company
paid $3,333,000 to the defendants upon consummation of the settlement agreement
and agreed to pay an additional $6,667,000 upon the earlier of February 27, 1998
or the sale of the Company's common stock in an initial public offering. The
Company has the option of paying a portion of this remaining amount in common
stock at a designated fixed value.
 
     The Company engaged a third party valuation firm to value the United
Kingdom marketing rights and the prepaid patent license agreement acquired as a
result of the settlement agreement and assigned values to the liabilities
identified as a result of the court judgment. The Company then allocated the
$10,000,000 of consideration to the liabilities identified and the intangible
assets acquired on a pro rata basis. As a result of this allocation and in
accordance with APB Opinion No. 17, "Intangible Assets," the Company allocated
$8,800,000 of the consideration to the United Kingdom marketing rights and the
prepaid patent license agreement acquired. The Company has assigned an estimated
useful life of 10 years to the United Kingdom marketing rights and the prepaid
patent license agreement.
 
     The Company incurred legal expenses, which were included in general and
administrative expenses, in 1994, 1995, 1996 and the six months ended June 30,
1996 and 1997 of $549,000, $1,320,000, $2,513,000, $649,000 and $52,000,
respectively, related to this litigation.
 
     Various other legal actions arising in the normal course of business have
been brought against the Company and certain of its subsidiaries. Management
believes that the ultimate resolution of the these actions will not have a
material adverse effect on the Company's financial position or results of
operations.
 
NOTE 15. OTHER COMMITMENTS
 
     Commitments for the remodeling of existing facilities and purchase of
capital equipment over the next year are approximately $2,849,000 and
$7,686,000, respectively, as of December 31, 1996 and June 30, 1997.
 
NOTE 16. SUBSEQUENT EVENTS
 
  Compensation Plans
 
     In June 1997, the Board of Directors and the stockholders of the Company
adopted the following compensation plans:
 
     The 1997 Equity Incentive Plan provides for grants of incentive stock
options to employees (including officers and employee directors) and
nonqualified stock options to employees, officers, directors, consultants,
independent contractors and advisors of the Company. The exercise price of all
incentive stock options must be equal to the fair market value of the Company's
common stock on the date of grant. The exercise price of

            AND FOR THE SIX MONTHS ENDED JUNE 30, 1997 IS UNAUDITED)
 
all nonqualified stock options must be at least equal to 85% of that value. A
total of 2,000,000 shares of common stock are reserved for future issuances
under the plan.
 
     The 1997 Directors Stock Option Plan provides for grants of nonqualified
stock options to certain non-employee directors of the Company. The exercise
price per share of all options granted under the plan must be equal to the fair
market value of the Company's common stock on the date of grant. A total of
300,000 shares of common stock are reserved for future issuances under the plan.
 
     The 1997 Employee Stock Purchase Plan will be implemented by an offering
commencing on the date of the closing of the proposed initial public offering.
The plan permits employees to purchase common stock at a price equal to 85% of
the fair market value of the Company's common stock. A total of 400,000 shares
of common stock are reserved for future issuances under the plan.
 
  Financing
 
     Effective upon the closing of a public offering of the Company's common
stock, the Company intends to amend and restate the commercial lending facility
(the "Revised Agreement") and has received a commitment from its bank for a
modification to the Revised Agreement under which the Company could borrow up to
$20 million in revolving credit loans. Outstanding borrowings under the Revised
Agreement are expected to fluctuate based on investment levels in working
capital and property and equipment. The Company expects that the Revised
Agreement will terminate on June 30, 2000, and would be secured by a pledge of
the Company's stock in its subsidiaries and the Company's inventory and accounts
receivable. Borrowings under the Revised Agreement would bear interest at
Comerica's prime rate or at Comerica's eurodollar rate plus a specified margin
that varies based on the Company's ratio of debt to tangible net worth.
 
  Loans to Officer
 
     In April 1997, the Company loaned a total of $892,195 to certain employees
of the Company, of which $550,923 is a full-recourse promissory note loaned to
the Company's Vice President, U.S. Sales. All the loans, except for the loan to
this officer, are non-recourse but are secured by a total of 228,846 shares of
the Company's Common Stock, 102,212 of which have been pledged by the officer.
The loans bear interest at a rate of 6%, payable on or before the earliest to
occur of the one year anniversary of each loan, respectively, termination of
employment, liquidation or dissolution of the Company or, under certain
circumstances, merger or consolidation of the Company.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Section 145 of the Delaware General Corporation Law Code authorizes a court
to award, or a corporation's Board of Directors to grant, indemnity to directors
and officers in terms sufficiently broad to permit such indemnification under
certain circumstances for liabilities (including reimbursement for expenses
incurred) arising under the Securities Act of 1933, as amended (the "Securities
Act"). Article VI of the Registrant's Bylaws provides for mandatory
indemnifications of its directors and officers and permissible indemnifications
of employees and other agents to the maximum extent permitted by the Delaware
General Corporation Law. In addition, the Registrant has entered into Indemnity
Agreements with its officers and directors, and has entered into a Registration
Rights Agreement with certain of its stockholders providing for, among other
things, indemnification of selling stockholders under certain circumstances.
Reference is also made to Section 9 of the Underwriting Agreement, which
provides for the indemnification of officers, directors and controlling persons
of the Registrant against certain liabilities.
 
     The indemnification provision in the Bylaws, and the indemnity agreements
entered into between the Registrant and its directors and executive officers,
may be sufficiently broad to permit indemnification of the Registrant's
directors and executive officers for liabilities arising under the Securities
Act.
 
     As authorized by the Registrant's Bylaws, the Registrant, with approval by
the Registrant's Board of Directors, has applied for, and expects to obtain,
directors' and officers' liability insurance with a per claim and annual
aggregate coverage limit of $30 million.
 
     Reference is made to the following documents filed as exhibits to this
Registration Statement regarding relevant indemnification provisions described
above and elsewhere herein:

ITEM 17. UNDERTAKINGS
 
     The undersigned Registrant hereby undertakes to provide to the Underwriter
at the closing specified in the Underwriting Agreement certificates in such
denominations and registered in such names as required by the Underwriter to
permit prompt delivery to each purchaser.
 
     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions described under Item 14 above, or
otherwise, the Registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Securities Act and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by the Registrant of expenses incurred or paid by a director, officer or
controlling person of the Registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.
 
     The undersigned Registrant hereby undertakes that:
 
          (1) For purposes of determining any liability under the Securities
     Act, the information omitted from the form of prospectus filed as part of
     this Registration Statement in reliance upon Rule 430A and contained in a
     form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act shall be deemed to be part of this
     Registration Statement as of the time it was declared effective.
 
          (2) For the purpose of determining any liability under the Securities
     Act, each post-effective amendment that contains a form of prospectus shall
     be deemed to be a new registration statement relating to the securities
     offered therein, and the offering of such securities at that time shall be
     deemed to be the initial bona fide offering thereof.

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors and Stockholders
Ocular Sciences, Inc.
 
Under date of February 14, 1997, except as to Notes 1 and 16 of the Notes to
Consolidated Financial Statements, which are as of July 14, 1997, we reported on
the consolidated balance sheets of Ocular Sciences, Inc. as of December 31, 1995
and 1996, and the related consolidated statements of income, stockholders
equity, and cash flows for each of the years in the three-year period ended
December 31, 1996, which are included in the prospectus. In connection with our
audits of the aforementioned consolidated financial statements, we also audited
the related consolidated financial statement schedule included in the
registration statement. This financial statement schedule is the responsibility
of the Company's management. Our responsibility is to express an opinion on this
financial statement schedule based on our audits.
 
In our opinion, such financial statement schedule, when considered in relation
to the basic consolidated financial statements taken as a whole, presents
fairly, in all material respects, the information set forth therein.

Ladies and Gentlemen:

         Ocular Sciences, Inc., a Delaware corporation (the "Company"), proposes
to issue and sell to the several Underwriters named in Schedule II hereto (the
"Underwriters"), and certain stockholders of the Company (the "Selling
Stockholders") named in Schedule I hereto severally propose to sell to the
several Underwriters, an aggregate of 7,200,000 shares of the Common Stock (par
value $0.001 per share) of the Company (the "Firm Shares"), of which 3,600,000
shares are to be issued and sold by the Company and 3,600,000 shares are to be
sold by the Selling Stockholders, each Selling Stockholder selling the amount
set forth opposite such Selling Stockholder's name in Schedule I hereto. The
Company is successor by merger to O.S.I. Corporation, a California corporation
(the "Predecessor"), as a result of a reincorporation transaction that became
effective on ____________, 1997 (the "Reincorporation"). For the purposes of
Section 1 hereof, all references to "Company" shall also refer to the
Predecessor prior to the Reincorporation.

         Certain of the Selling Stockholders also propose to sell to the several
Underwriters not more than an additional 1,080,000 shares of its Common Stock
(par value $0.001 per share) (the "Additional Shares") if and to the extent that
you, as Managers of the offering, shall have determined to exercise, on behalf
of the Underwriters, the right to purchase such shares of Common Stock granted
to the Underwriters in Section 3 hereof. The Firm Shares and the Additional
Shares are hereinafter collectively referred to as the "Shares." The shares of
Common Stock (par value $0.001 per share) of the Company to be outstanding after
giving effect to the sales contemplated hereby are hereinafter referred to as
the "Common Stock." The Company and the Selling Stockholders are hereinafter
sometimes collectively referred to as the "Sellers."

         The Company has filed with the Securities and Exchange Commission (the
"Commission") a registration statement, including a prospectus, relating to the
Shares. The registration statement as amended at the time it becomes effective,
including the information (if any) deemed to be part of the registration
statement at the time of effectiveness pursuant to Rule 430A under the
Securities Act of 1933, as amended (the "Securities Act"), is hereinafter
referred to as the "Registration Statement;" the prospectus in the form first
used to confirm sales of Shares is hereinafter referred to as the "Prospectus."
If the Company has filed an abbreviated registration statement to register
additional shares of Common Stock pursuant to Rule 462(b) under the Securities
Act (the "Rule 462 Registration Statement"), then any reference herein to the
term "Registration Statement" shall be deemed to include such Rule 462
Registration Statement.

         As part of the offering contemplated by this Agreement, Morgan Stanley
& Co. Incorporated ("Morgan Stanley") has agreed to reserve out of the Shares
set forth opposite its name on Schedule II to this Agreement, up to ____________
shares, for sale to the Company's employees, officers, and directors and other
parties associated with the Company (collectively, "Participants"), as set forth
in the Prospectus under the heading "Underwriting" (the "Directed Share
Program"). The Shares to be sold by Morgan Stanley pursuant to the Directed
Share Program (the "Directed Shares") will be sold by Morgan Stanley pursuant to
this Agreement at the public offering price. Any Directed Shares not orally
confirmed for purchase by any Participants by the end of the first business day
after the date on which this Agreement is executed will be offered to the public
by Morgan Stanley as set forth in the Prospectus.

    no proceedings for such purpose are pending before or threatened by the
    Commission.

        (b)     (i) The Registration Statement, when it became effective, did
    not contain and, as amended or supplemented, if applicable, will not contain
    any untrue statement of a material fact or omit to state a material fact
    required to be stated therein or necessary to make the statements therein
    not misleading, (ii) the Registration Statement and the Prospectus comply
    and, as amended or supplemented, if applicable, will comply in all material
    respects with the Securities Act and the applicable rules and regulations of
    the Commission thereunder and, (iii) the Prospectus does not contain and, as
    amended or supplemented, if applicable, will not contain any untrue
    statement of a material fact or omit to state a material fact necessary to
    make the statements therein, in the light of the circumstances under which
    they were made, not misleading, except that the representations and
    warranties set forth in this Section l(b) do not apply to statements or
    omissions in the Registration Statement or the Prospectus based upon
    information relating to any Underwriter furnished to the Company in writing
    by such Underwriter through you expressly for use therein.

    to conduct its business as described in the Prospectus and is duly qualified
    to transact business and is in good standing in each jurisdiction in which
    the conduct of its business or its ownership or leasing of property requires
    such qualification, except to the extent that the failure to be so qualified
    or be in good standing would not have a material adverse effect on the
    Company and its Subsidiaries (as defined below), taken as a whole.

    ("OSI Puerto Rico"), O.S.I. Canada Corporation, a New Brunswick corporation

    jurisdiction in which the conduct of its business or its ownership or
    leasing of property requires such qualification, except to the extent that
    the failure to be so qualified or be in good standing would not have a
    material adverse effect on the Company and its Subsidiaries, taken as a
    whole. All of the issued shares of capital stock of each Subsidiary have
    been duly and validly authorized and issued, are fully paid and
    non-assessable, and are beneficially owned directly by the Company, free and
    clear of all liens, encumbrances, equities or claims.

        (e) The Company and each of its Subsidiaries have good and marketable
    title to all personal and real property owned by them that is material to
    the business of the Company and its Subsidiaries, taken as a whole, in each
    case free and clear of all liens, encumbrances and defects except such as
    are described in the Prospectus or such as do not materially affect the
    value of such property and do not interfere with the use made and proposed
    to be made of such property by the Company and each of its Subsidiaries; and
    any real property and buildings held under lease by the Company and each of
    its Subsidiaries are held by them under valid, subsisting and enforceable
    leases except with such exceptions as are not material to the Company and do
    not interfere with the current and proposed use of such property and
    buildings by the Company and each of its Subsidiaries, in each case except
    as described in or contemplated by the Prospectus.

    not materially and adversely affect the condition, financial or otherwise,

    singly or in the aggregate, have a material adverse effect on the Company
    and its Subsidiaries, taken as a whole.

    inventions, products or processes of the Company and its Subsidiaries
    referred to in the Prospectus do not, to the best knowledge of the Company,

         3. AGREEMENTS TO SELL AND PURCHASE. Each Seller, severally and not
jointly, hereby agrees to sell to the several Underwriters, and each
Underwriter, upon the basis of the representations and warranties herein
contained, but subject to the conditions hereinafter stated, agrees, severally
and not jointly, to purchase from such Seller at $______ a share (the "Purchase
Price") the number of Firm Shares (subject to such adjustments to eliminate
fractional shares as you may determine) that bears the same proportion to the
number of Firm Shares to be sold by such Seller as the number of Firm Shares set
forth in Schedule II hereto opposite the name of such Underwriter bears to the
total number of Firm Shares.

         On the basis of the representations and warranties contained in this
Agreement, and subject to its terms and conditions, each of the Selling
Stockholders agree to sell to the Underwriters, severally and not jointly, and
the Underwriters shall have a one-time right to purchase, at the Purchase Price,
such number of Additional shares as is set forth with respect to such Selling
Stockholder on Schedule I hereto.  If you, on behalf of the Underwriters, elect
to exercise such option, you shall so notify the Selling Stockholders in writing
not later than 30 days after the date of this Agreement, which notice shall
specify the number of Additional Shares to be purchased by the Underwriters and
the date on which such shares are to be purchased. Such date may be the same as
the Closing Date (as defined below) but not earlier than the Closing Date nor
later than ten business days after the date of such notice. Additional Shares
may be purchased as provided in Section 5 hereof solely for the purpose of
covering over-allotments made in connection with the offering of the Firm
Shares. If any Additional Shares are to be purchased, each Underwriter agrees,
severally and not jointly, to purchase the number of Additional Shares (subject
to such adjustments to eliminate fractional shares as you may determine) that
bears the same proportion to the total number of Additional Shares to be
purchased as the number of Firm Shares set forth in Schedule II hereto opposite
the name of such Underwriter bears to the total number of Firm Shares.

         Each Seller hereby agrees that, without the prior written consent of
Morgan Stanley on behalf of the Underwriters, it will not, during the period
ending 180 days after the date of the Prospectus, (i) offer, pledge, sell,
contract to sell, sell any option or contract to purchase, purchase any option
or contract to sell, grant any option, right or warrant to purchase or otherwise
transfer or dispose of, directly or indirectly, any shares of Common Stock or
any securities convertible into or exercisable or exchangeable for Common Stock
or (ii) enter into any swap or other arrangement that transfers to another, in
whole or in part, any of the economic consequences of ownership of the Common
Stock, whether any such transaction described in clause (i) or (ii) above is to
be settled by delivery of Common Stock or such other securities, in cash or
otherwise (the "Market Stand-Off"). The foregoing sentence shall not apply to
(A) the Shares to be sold hereunder, (B) the issuance by the Company of shares
of Common Stock upon the exercise of an option or warrant or the conversion of a
security outstanding on the date hereof, (C) options issued under the 1989 Plan,
1992 Plan, the 1997 Equity Incentive Plan, the 1997 Directors Stock Option Plan,
and the shares issuable upon exercise thereof, (D) shares issued under the 1997
Employee Stock Purchase Plan and the shares issuable upon exercise thereof;
provided, however, that any receiver of securities issued under (B), (C) or (D)

agrees that, without the prior written consent of Morgan Stanley on behalf of
the Underwriters, it will not, during the period ending 180 days after the

       (exclusive of any amendments or supplements thereto subsequent to the
       date of this Agreement) that, in your judgment, is material and adverse
       and that makes it, in your judgment, impracticable to market the Shares

         (b) The Underwriters shall have received on the Closing Date a
     certificate, dated the Closing Date and signed by an executive officer of

         governmental body or agency is required for the performance by the
         Company and the Predecessor of their respective obligations under the
         Plan of Merger except such as have been obtained or are not material to
         the Company; the consummation of the Reincorporation does not
         contravene, or result in any breach of, or constitute a default under
         (or constitute any event which with notice, lapse of time or both would
         constitute a breach of or default under), any provision of any Material
         Agreement;

                  (xviii) the merger contemplated by the Plan of Merger is
         effective under the laws of the State of California and the State of
         Delaware; the Company has succeeded to all of the rights, privileges,
         powers and franchises, and is subject to all of the restrictions,

         counsel, the Company has succeeded to all of the rights of the
         Predecessor with respect to each Material Agreement of the Predecessor,
         and all required material consents to the merger and assignments with
         respect to such Material Agreements have been obtained; all of the

         preferences and privileges (except for differences resulting from
         applicable law) as described in the Prospectus; all of the outstanding
         options of the Predecessor outstanding as of the date set forth in the

         the Company as described in the Prospectus, other than options which
         have terminated or expired by their terms and not as a result of the
         Reincorporation; the issuance of capital stock by the Company in the
         Reincorporation was in compliance with all applicable registration and
         qualification provisions of state securities or blue sky laws as are
         identified therein and was exempt from registration under the
         Securities Act; and

                  (xix) The statements in the Prospectus under the captions
         "Risk Factors--Regulatory Approvals Uncertain" and
         "Business--Government Regulation," insofar as such statements purport
         to summarize applicable provisions of the Federal Food, Drug and
         Cosmetic Act and the regulations promulgated thereunder, are accurate
         summaries in all material respects of the provisions purported to be
         summarized under such captions in the Prospectus.

         In addition, such counsel shall state that in addition to rendering
legal advice and assistance to the Company in the course of the preparation of
the Registration Statement and the Prospectus, involving, among other things,
discussions and inquiries concerning various legal matters and the review of
certain corporate records, documents and proceedings, such counsel also
participated in conferences with certain officers and other representatives of
the Company, including its independent certified public accountants and with the
Underwriters and their counsel, at which the contents of the Registration
Statement and the Prospectus and related matters were discussed; provided, such
counsel may state that they have not independently verified the accuracy,
completeness or fairness of the information contained in the Registration
Statement and Prospectus.

         In addition to the matters set forth above, counsel rendering the
foregoing opinion shall also include a statement to the effect that nothing has
come to the attention of such counsel that causes it to believe that (i) the
registration statement (except as to the financial statements, the notes
thereto, the schedules and the other financial and statistical data contained
therein, as to which such counsel need not express any opinion or belief) at the
date the Registration Statement became effective contained any untrue statement
of a material fact or omitted to state a material fact required to be stated
therein or necessary to make the statements therein not misleading, (ii) the
Prospectus (except as to the financial statements, the notes thereto, the
schedules and the other financial and statistical data contained therein, as to
which such counsel need not express an opinion or belief) as of its date
contained or contains any untrue statement of a material fact or omitted or
omits to state a material fact necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading and (iii) the Registration Statement or the Prospectus (except as to
the financial statements, the notes thereto, the schedules and the other
financial and statistical data contained therein, as to which such counsel need
not express any opinion or belief) did not comply as to form in all material
respects with the Securities Act and the applicable rules and regulations
thereunder.

                  (d) The Underwriters shall have received on the Closing Date
         an opinion or opinions of counsel for the Selling Stockholders (who may
         also be counsel for the Company) to the effect that with respect to the
         Selling Stockholder that such counsel represents:

                           (i) this Agreement has been duly authorized, executed
                  and delivered by or on behalf of such Selling Stockholder;

                  Stockholder of, and the performance by such Selling
                  Stockholder of its obligations under, this Agreement and the
                  Custody Agreement and Power of Attorney of such Selling
                  Stockholder does not contravene any provision of applicable
                  law, or the certificate of incorporation or bylaws of such
                  Selling Stockholder (if such Selling Stockholder is a
                  corporation) or, to such counsel's knowledge, any agreement or
                  other instrument binding upon such Selling Stockholder (where
                  such agreements and instruments have been identified to such
                  counsel by such Selling Stockholder as all of the material

                  Stockholder) or, to such counsel's knowledge, any judgment,
                  order or decree of any governmental body, agency or court
                  having jurisdiction over such Selling Stockholder, and, to
                  such counsel's knowledge, no consent, approval, authorization
                  or order of, or qualification with, any governmental body or
                  governmental agency is required for the performance by such
                  Selling Stockholder of its obligations under this Agreement or
                  the Custody Agreement or Power of Attorney of such Selling
                  Stockholder, except such as may be required under the
                  Securities Act or by the securities or Blue Sky laws of the
                  various states or international jurisdiction in connection
                  with the offer and sale of the Shares (as to which such
                  counsel need not opine);

                           (iii) to such counsel's knowledge, such Selling
                  Stockholder has the legal right and power, and all
                  authorization and approval required by law, to enter into this
                  Agreement and the Custody Agreement and Power of Attorney of
                  such Selling Stockholder and to sell, transfer and deliver the
                  Shares to be sold by such Selling Stockholder;

                           (iv) the Custody Agreement and the Power of Attorney
                  of such Selling Stockholder have been duly authorized,
                  executed and delivered by such Selling Stockholder and are
                  valid and binding agreements of such Selling Stockholder; and

                           (v) upon delivery of and payment for the stock to be
                  sold by such Selling Stockholder as provided in this Agreement
                  and upon registration of the Shares in the names of the
                  Underwriters (or their nominees) in the stock records of the
                  Company (but without having conducted a search of the records
                  of any governmental authority or any third person), the
                  Underwriters will be the owners of the Shares, free and clear
                  of any adverse claim, security interests, liens, equities and
                  other encumbrances, provided that the Underwriters are
                  purchasing the Shares in good faith and without notice of any
                  adverse claim.

                  The opinions of Fenwick & West LLP described in paragraphs (c)
and (d) above (and any opinions of counsel for any Selling Stockholder referred
to in the immediately preceding paragraph) shall be rendered to the Underwriters
at the request of the Company or one or more of the Selling Stockholders, as the
case may be, and shall so state therein.

                  (e) The Underwriters shall have received on the Closing Date
         an opinion of Moore & Blatch, counsel for OSL, dated the Closing Date,
         to the effect that:

                           (i) OSL has been duly incorporated, is validly
                  existing as a corporation in good standing under the laws of
                  the jurisdiction of its incorporation, has the corporate power
                  and authority to own its property and to conduct its business
                  as described in the Prospectus and is duly qualified to
                  transact business and is in good standing in the United
                  Kingdom;


                                       12
<PAGE>   14


                           (ii) all of the issued shares of capital stock of OSL
                  have been duly validly authorized and issued, are fully paid
                  and non-assessable, and owned directly by the Company, free
                  and clear of all liens and encumbrances;

                           (iii) the execution and delivery by the Company of,
                  and the performance by the Company of its obligations under,
                  this Agreement will not contravene any provision of English
                  law or the Memorandum of Articles of Association of OSL;

                  (f) The Underwriters shall have received on the Closing Date
         an opinion of Bird, Bird and Huestres, counsel for OSI Puerto Rico,
         dated as of the Closing Date, that OSI Puerto Rico is duly qualified to
         transact business and is in good standing in each jurisdiction in which
         the conduct of its business or its ownership or leasing of property
         requires such qualification, except to the extent that the failure to
         be so qualified or be in good standing would not have a material
         adverse effect on OSI Puerto Rico.

                  (g) The Underwriters shall have received on the Closing Date
         an opinion of Gunderson Dettmer Stough Villeneuve Franklin & Hachigian,
         LLP, counsel for the Underwriters, dated the Closing Date, covering the
         matters referred to in the first clause of subparagraph (c)(i), in
         subparagraphs (c)(vi), (c)(viii), (c)(ix), (c)(xi) (but only as to the
         opinion in clause (I) thereof) and (c)(xiii) (but only as to the
         statements in the Prospectus under "Description of Capital Stock" and
         "Underwriters") and the second paragraph following the enumerated
         opinions in paragraph (c) above. Such opinion shall also cover the
         matters referred to in subparagraph (d)(i).

                  (h) The Underwriters shall have received, on each of the date
         hereof and the Closing Date, a letter dated the date hereof or the
         Closing Date, as the case may be, in form and substance satisfactory to
         the Underwriters, from KPMG Peat Marwick LLP, independent certified
         public accountants, containing statements and information of the type
         ordinarily included in accountants' "comfort letters" to underwriters
         with respect to the financial statements and certain financial
         information contained in the Registration Statement and the Prospectus;
         provided that the letter delivered on the Closing Date shall use a
         "cut-off date" not earlier than the date hereof.

                  (i) The "lock-up" agreements between you and certain
         stockholders, officers and directors of the Company relating to sales
         and certain other dispositions of shares of Common Stock or certain
         other securities, delivered to you on or before the date hereof, shall
         be in full force and effect on the Closing Date.

         The several obligations of the Underwriters to purchase Additional
Shares hereunder are subject to the delivery to you on the Option Closing Date
of such documents as you may reasonably request with respect to the good
standing of the Company, the due authorization and issuance of the Additional
Shares and other matters related to the Additional Shares.

         7. COVENANTS OF THE COMPANY. In further consideration of the agreements
of the Underwriters herein contained, the Company covenants with each

         any supplements and amendments thereto or to the Registration Statement
         as you may reasonably request.

                  (b) Before amending or supplementing the Registration
         Statement or the Prospectus, to furnish to you a copy of each such

         prospectus required to be filed pursuant to such Rule.

                  (c) If, during such period after the first date of the public
         offering of the Shares as in the opinion of counsel for the
         Underwriters the Prospectus is required by law to be delivered in
         connection with sales by an Underwriter or dealer, any event shall
         occur or condition exist as a result of which it is necessary to amend
         or supplement the Prospectus in order to make the statements therein,
         in the light of the circumstances when the Prospectus is delivered to a
         purchaser, not misleading, or if, in the opinion of counsel for the
         Underwriters, it is necessary to amend or supplement the Prospectus to
         comply with applicable law, forthwith to prepare, file with the
         Commission and furnish, at its own expense, to the Underwriters and to
         the dealers (whose names and addresses you will furnish to the Company)
         to which Shares may have been sold by you on behalf of the Underwriters
         and to any other dealers upon request, either amendments or supplements
         to the Prospectus so that the statements in the Prospectus as so
         amended or supplemented will not, in the light of the circumstances
         when the Prospectus is delivered to a purchaser, be misleading or so
         that the Prospectus, as amended or supplemented, will comply with law.

                  (d) To endeavor to qualify the Shares for offer and sale under
         the securities or Blue Sky laws of such jurisdictions as you shall

         rules and regulations of the Commission thereunder.

                  (f) To pay or cause to be paid all expenses incident to the
         performance of its obligations under this Agreement, including: (i) the

         in connection with the preparation and filing of the Registration
         Statement, any preliminary prospectus, the Prospectus and amendments

         associated therewith, and the mailing and delivering of copies thereof
         to the Underwriters and dealers, in the quantities hereinabove

         reasonable fees and disbursements of counsel for the Underwriters in
         connection with the Blue Sky memorandum, (iv) all filing fees and
         reasonable disbursements of counsel to the Underwriters incurred in

         show slides and graphics, fees and expenses of any consultants engaged
         in connection with the road show presentations with the prior approval
         of the Company, travel and lodging expenses of the representatives and
         officers of the Company and any such consultants and, if approved by
         the Company, the cost of any aircraft chartered in connection with the
         road show, and (ix) all other costs and expenses incident to the
         performance of the obligations of the Company hereunder for which

         however, that except as provided in this Section, Section 9 entitled
         "Indemnity and Contribution", and the last paragraph of Section 11
         below, the Underwriters will pay all of their costs and expenses,
         including fees and disbursements of their counsel, stock transfer taxes
         payable on resale of any of the Shares by them, and any advertising
         expenses connected with any offers they may make.

                  (g) To not release any shares of Common Stock from any
         restrictions imposed upon such shares by the Lock-Up Agreements without
         the prior written consent of Morgan Stanley.

                  (h) That in connection with the Directed Share Program, the
         Company will ensure that the Directed Shares will be restricted to the
         extent required by the NASD or the NASD rules from sale, transfer,
         assignment, pledge or hypothecation for a period of three months
         following the date of the effectiveness of the Registration Statement.
         Morgan Stanley will notify the Company as to which Participants will
         need to be so restricted. The Company will direct the transfer agent to
         place stop-transfer restrictions upon such securities for such period
         of time.

                  (i) To pay all reasonable fees and disbursements of counsel
         incurred by the Underwriters in connection with the Directed Share
         Program and stamp duties, similar taxes or duties or other taxes, if
         any, incurred by the Underwriters in connection with the Directed Share
         Program; provided such fees and disbursements would not otherwise have
         been incurred by the Underwriters in connection with the sale of the
         Shares.

         Furthermore, the Company covenants with Morgan Stanley that the Company
will comply with all applicable securities and other applicable laws, rules and
regulations in each foreign jurisdiction in which the Directed Shares are
offered in connection with the Directed Share Program.

         8. EXPENSES OF SELLING STOCKHOLDERS. The Underwriters shall not be

agrees to pay or cause to be paid (i) all taxes, if any, on the transfer and
sale of the Shares being sold by such Selling Stockholder and (ii) such Selling
Stockholder's pro rata share of expenses of counsel for the Selling
Stockholders.

         9. INDEMNITY AND CONTRIBUTION.

        (a) The Company agrees to indemnify and hold harmless each Underwriter
    and each person, if any, who controls any Underwriter within the meaning of
    either Section 15 of the Securities Act or Section 20 of the Securities
    Exchange Act of 1934, as amended (the "Exchange Act"), from and against any
    and all losses, claims, damages and liabilities (including, without
    limitation, any legal or other expenses reasonably incurred in connection
    with defending or investigating any such action or claim) caused by any
    untrue statement or alleged untrue statement of a material fact contained in
    the Registration Statement or any amendment thereof, any preliminary
    prospectus or the Prospectus (as amended or supplemented if the Company
    shall have furnished any amendments or supplements thereto) or caused by any
    omission or alleged omission to state therein a material fact required to be
    stated therein or necessary to make the statements therein not misleading,
    except insofar as such losses, claims, damages or liabilities are caused by
    any such untrue statement or omission or alleged untrue statement or
    omission based upon information relating to any Underwriter furnished to the
    Company in writing by such Underwriter through you expressly for use
    therein; provided, however, that the foregoing indemnity agreement with
    respect to any preliminary prospectus shall not inure to the benefit of any
    Underwriter, or any person controlling such Underwriter, from whom the
    person asserting any such losses, claims, damages or liabilities purchased
    Shares, if a copy of the Prospectus (as then amended or supplemented if the
    Company shall have furnished any amendments or supplements thereto) was not
    sent or given by or on behalf of such Underwriter to such person, if
    required by law so to have been delivered, at or prior to the written
    confirmation of the sale of the Shares to such person, and if the Prospectus
    (as so amended or supplemented) would have cured the defect giving rise to
    such loss, claim, damage or liability.






                                       15

<PAGE>   17


        (b) The Company agrees to indemnify and hold harmless Morgan Stanley and
    each person, if any, who controls Morgan Stanley within the meaning of
    either Section 15 of the Securities Act or Section 20 of the Exchange Act
    ("Morgan Stanley Entities"), from and against any and all losses, claims,
    damages and liabilities (including, without limitation, any legal or other
    expenses reasonably incurred in connection with defending or investigating
    any such action or claim) (i) caused by any untrue statement or alleged
    untrue statement of a material fact contained in the prospectus wrapper
    material prepared by or with the consent of the Company for distribution in
    foreign jurisdictions in connection with the Directed Share Program attached
    to the Prospectus or any preliminary prospectus, or caused by any omission
    or alleged omission to state therein a material fact required to be stated
    therein or necessary to make the statement therein, when considered in
    conjunction with the Prospectus or any applicable preliminary prospectus,
    not misleading; (ii) caused by the failure of any Participant to pay for and
    accept delivery of the shares which, immediately following the effectiveness
    of the Registration Statement, were subject to a properly confirmed
    agreement to purchase; or (iii) related to, arising out of, or in connection
    with the Directed Share Program, provided that, the Company shall not be
    responsible under this subparagraph (iii) for any losses, claim, damages or
    liabilities (or expenses relating thereto) that are finally judicially
    determined to have resulted from the bad faith or gross negligence of Morgan
    Stanley Entities.

        (c) Each Selling Stockholder agrees, severally and not jointly, to
    indemnify and hold harmless each Underwriter, the Company, its directors,
    its officers who sign the Registration Statement and each person, if any,
    who controls any Underwriter or the Company within the meaning of either
    Section 15 of the Securities Act or Section 20 of the Exchange Act, from and
    against any and all losses, claims, damages and liabilities (including,
    without limitation, any legal or other expenses reasonably incurred in
    connection with defending or investigating any such action or claim) caused
    by any untrue statement or alleged untrue statement of a material fact
    contained in the Registration Statement or any amendment thereof, any
    preliminary prospectus or the Prospectus (as amended or supplemented if the
    Company shall have furnished any amendments or supplements thereto), or
    caused by any omission or alleged omission to state therein a material fact
    required to be stated therein or necessary to make the statements therein
    not misleading, but only with reference to information relating to such
    Selling Stockholder furnished in writing by or on behalf of such Selling
    Stockholder expressly for use in the Registration Statement, any preliminary
    prospectus, the Prospectus or any amendments or supplements thereto;
    provided, however, that the foregoing indemnity agreement with respect to
    any preliminary prospectus shall not inure to the benefit of any
    Underwriter, or any person controlling such Underwriter, from whom the
    person asserting any such losses, claims, damages or liabilities purchased
    Shares, if a copy of the Prospectus (as then amended or supplemented if the
    Company shall have furnished any amendments or supplements thereto) was not
    sent or given by or on behalf of such Underwriter to such person, if
    required by law so to have been delivered, at or prior to the written
    confirmation of the sale of the Shares to such person, and if the Prospectus
    (as so amended or supplemented) would have cured the defect giving rise to
    such loss, claim, damage or liability.

        (d) Each Underwriter agrees, severally and not jointly, to indemnify and
    hold harmless the Company, the Selling Stockholders, the directors of the
    Company, the officers of the Company who sign the Registration Statement and
    each person, if any, who controls the Company or any Selling Stockholder
    within the meaning of either Section 15 of the Securities Act or Section 20
    of the Exchange Act from and against any and all losses, claims, damages and
    liabilities (including, without limitation, any legal or other expenses
    reasonably incurred in connection with defending or investigating any such
    action or claim) caused by any untrue statement or alleged untrue statement
    of a material fact contained in the Registration Statement or any amendment
    thereof, any preliminary prospectus or the Prospectus (as amended or
    supplemented if the Company shall have furnished any amendments or
    supplements thereto), or caused by any omission or alleged omission to state
    therein a material fact required to be stated therein or necessary to make
    the statements therein not misleading, but only with reference to
    information relating to such Underwriter furnished to the Company in writing
    by or on behalf of such Underwriter through you expressly for use in the
    Registration Statement, any preliminary prospectus, the Prospectus or any
    amendments or supplements thereto.







                                       16

<PAGE>   18


        (e) In case any proceeding (including any governmental investigation)
    shall be instituted involving any person in respect of which indemnity may
    be sought pursuant to paragraph (a), (b), (c) or (d) of this Section 9, such
    person (the "indemnified party") shall promptly notify the person against
    whom such indemnity may be sought (the "indemnifying party") in writing and
    the indemnifying party, upon request of the indemnified party, shall retain
    counsel reasonably satisfactory to the indemnified party to represent the
    indemnified party and any others the indemnifying party may reasonably
    designate in such proceeding and shall pay the fees and disbursements of
    such counsel related to such proceeding. In any such proceeding, any
    indemnified party shall have the right to retain its own counsel, but the
    fees and expenses of such counsel shall be at the expense of such
    indemnified party unless (i) the indemnifying party and the indemnified
    party shall have mutually agreed to the retention of such counsel or (ii)
    the named parties to any such proceeding (including any impleaded parties)
    include both the indemnifying party and the indemnified party and
    representation of both parties by the same counsel would be inappropriate
    due to actual or potential differing interests between them. It is
    understood that the indemnifying party shall not, in respect of the legal
    expenses of any indemnified party in connection with any proceeding or
    related proceedings in the same jurisdiction, be liable for the fees and
    expenses of more than one separate firm (in addition to any local counsel)
    for (i) all Underwriters and all persons, if any, who control any
    Underwriter within the meaning of either Section 15 of the Securities Act or
    Section 20 of the Exchange Act, (ii) the Company, its directors, its
    officers who sign the Registration Statement and each person, if any, who
    controls the Company within the meaning of either such Section and (iii) all
    Selling Stockholders and all persons, if any, who control any Selling
    Stockholder within the meaning of either such Section, and that all such
    fees and expenses shall be reimbursed as they are incurred. In the case of
    any such separate firm for the Underwriters and such control persons of the
    Underwriters, such firm shall be designated in writing by Morgan Stanley. In
    the case of any such separate firm for the Company, and such directors,
    officers and control persons of the Company, such firm shall be designated
    in writing by the Company. In the case of any such separate firm for the
    Selling Stockholders and such controlling persons of the Selling
    Stockholders, such firm shall be designated in writing by the persons named
    as attorneys-in-fact for the Selling Stockholders under the Powers of
    Attorney. The indemnifying party shall not be liable for any settlement of
    any proceeding effected without its written consent, but if settled with
    such consent or if there be a final judgment for the plaintiff, the
    indemnifying party agrees to indemnify the indemnified party from and
    against any loss or liability by reason of such settlement or judgment.
    Notwithstanding the foregoing sentence, if at any time an indemnified party
    shall have requested an indemnifying party to reimburse the indemnified
    party for fees and expenses of counsel as contemplated by the second and
    third sentences of this paragraph, the indemnifying party agrees that it
    shall be liable for any settlement of any proceeding effected without its
    written consent if (i) such settlement is entered into more than 30 days
    after receipt by such indemnifying party of the aforesaid request and (ii)
    such indemnifying party shall not have reimbursed the indemnified party in
    accordance with such request prior to the date of such settlement. No
    indemnifying party shall, without the prior written consent of the
    indemnified party, effect any settlement of any pending or threatened
    proceeding in respect of which any indemnified party is or could have been a
    party and indemnity could have been sought hereunder by such indemnified
    party, unless such settlement includes an unconditional release of such
    indemnified party from all liability on claims that are the subject matter
    of such proceeding. Notwithstanding anything contained herein to the
    contrary, if indemnity may be sought pursuant to Section 9(b) hereof in
    respect of such action or proceeding, then in addition to such separate firm
    for the indemnified parties, the indemnifying party shall be liable for the
    reasonable fees and expenses of not more than one separate firm (in addition
    to any local counsel) for Morgan Stanley for the defense of any losses,
    claims, damages and liabilities arising out of the Directed Share Program,
    and all persons, if any, who control Morgan Stanley within the meaning of
    either Section 15 of the Act or Section 20 of the Exchange Act.

        (f) To the extent the indemnification provided for in paragraph (a),
    (b), (c) or (d) of this Section 9 is unavailable to an indemnified party or
    insufficient in respect of any losses, claims, damages or liabilities
    referred to therein, then each indemnifying party under such paragraph, in
    lieu of indemnifying such indemnified party thereunder, shall contribute to
    the amount paid or payable by such indemnified party as a result of such
    losses, claims, damages or liabilities (i) in such proportion as is
    appropriate to reflect the relative benefits received by the indemnifying
    party or parties on the one hand and the







                                       17

<PAGE>   19

    indemnified party or parties on the other hand from the offering of the
    Shares or (ii) if the allocation provided by clause (i) above is not
    permitted by applicable law, in such proportion as is appropriate to reflect
    not only the relative benefits referred to in clause (i) above but also the
    relative fault of the indemnifying party or parties on the one hand and of
    the indemnified party or parties on the other hand in connection with the
    statements or omissions that resulted in such losses, claims, damages or
    liabilities, as well as any other relevant equitable considerations. The
    relative benefits received by the Company and the Selling Stockholders on
    the one hand and the Underwriters on the other hand in connection with the
    offering of the Shares shall be deemed to be in the same respective
    proportions as the net proceeds from the offering of the Shares (before
    deducting expenses) received by each Seller and the total underwriting
    discounts and commissions received by the Underwriters, in each case as set
    forth in the table on the cover of the Prospectus, bear to the aggregate
    Public Offering Price of the Shares. The relative fault of each Seller and
    the Underwriters shall be determined by reference to, among other things,
    whether the untrue or alleged untrue statement of a material fact or the
    omission or alleged omission to state a material fact relates to information
    supplied by such Seller or by the Underwriters and the parties' relative
    intent, knowledge, access to information and opportunity to correct or
    prevent such statement or omission. The Underwriters' respective obligations
    to contribute pursuant to this Section 9 are several in proportion to the
    respective number of Shares they have purchased hereunder, and not joint.

        (g) The Sellers and the Underwriters agree that it would not be just or
    equitable if contribution pursuant to this Section 9 were determined by pro
    rata allocation (even if the Underwriters were treated as one entity for
    such purpose) or by any other method of allocation that does not take
    account of the equitable considerations referred to in paragraph (f) of this
    Section 9. The amount paid or payable by an indemnified party as a result of
    the losses, claims, damages and liabilities referred to in the immediately
    preceding paragraph shall be deemed to include, subject to the limitations
    set forth above, any legal or other expenses reasonably incurred by such
    indemnified party in connection with investigating or defending any such
    action or claim. Notwithstanding the provisions of this Section 9, no
    Underwriter shall be required to contribute any amount in excess of the
    amount by which the total price at which the Shares underwritten by it and
    distributed to the public were offered to the public exceeds the amount of
    any damages that such Underwriter has otherwise been required to pay by
    reason of such untrue or alleged untrue statement or omission or alleged
    omission. No person guilty of fraudulent misrepresentation (within the
    meaning of Section 11(f) of the Securities Act) shall be entitled to
    contribution from any person who was not guilty of such fraudulent
    misrepresentation. The remedies provided for in this Section 9 are not
    exclusive and shall not limit any rights or remedies which may otherwise be
    available to any indemnified party at law or in equity.

        (h) The indemnity and contribution provisions contained in this Section
    9 and the representations, warranties and other statements of the Company
    and the Selling Stockholders contained in this Agreement shall remain
    operative and in full force and effect regardless of (i) any termination of
    this Agreement, (ii) any investigation made by or on behalf of any
    Underwriter or any person controlling any Underwriter, any Selling
    Stockholder or any person controlling any Selling Stockholder, or the
    Company, its officers or directors or any person controlling the Company and
    (iii) acceptance of and payment for any of the Shares. The aggregate
    liability of each Selling Stockholder under the indemnity and contribution
    agreements contained in this Section 9 and under the representations and
    warrants contained in paragraph (f) of Section 2 hereof shall be limited to
    an amount equal to the net proceeds received by such Selling Stockholder
    (before deducting expenses) from the offering of the Shares sold by such
    Selling Stockholder.

         10. TERMINATION. This Agreement shall be subject to termination by
notice given by you to the Company, if (a) after the execution and delivery of
this Agreement and prior to the Closing Date (i) trading generally shall have
been suspended or materially limited on or by, as the case may be, any of the
New York Stock Exchange, the American Stock Exchange, the National Association
of Securities Dealers, Inc., the Chicago Board of Options Exchange, the Chicago
Mercantile Exchange or the Chicago Board of Trade, (ii) trading of any
securities of the Company shall have been suspended on any exchange or in any
over-the-counter market, (iii) a general moratorium on commercial banking
activities in New York shall have been declared by either Federal or New York
State authorities or (iv) there shall have occurred any outbreak or escalation
of hostilities or any change in financial 






                                       18

markets or any calamity or crisis that, in your judgment, is material and
adverse and (b) in the case of any of the events specified in clauses (a)(i)
through (iv), such event, singly or together with any other such event, makes
it, in your judgment, impracticable to market the Shares on the terms and in the
manner contemplated in the Prospectus.

         11. EFFECTIVENESS: DEFAULTING UNDERWRITERS. This Agreement shall become
effective upon the execution and delivery hereof by the parties hereto.

         If, on the Closing Date or the Option Closing Date, as the case may be,
any one or more of the Underwriters shall fail or refuse to purchase Shares that
it has or they have agreed to purchase hereunder on such date, and the aggregate
number of Shares which such defaulting Underwriter or Underwriters agreed but
failed or refused to purchase is not more than one-tenth of the aggregate number
of the Shares to be purchased on such date, the other Underwriters shall be
obligated severally in the proportions that the number of Firm Shares set forth
opposite their respective names in Schedule II bears to the aggregate number of
Firm Shares set forth opposite the names of all such non-defaulting
Underwriters, or in such other proportions as you may specify, to purchase the
Shares which such defaulting Underwriter or Underwriters agreed but failed or
refused to purchase on such date; provided that in no event shall the number of
Shares that any Underwriter has agreed to purchase pursuant to this Agreement be
increased pursuant to this Section 11 by an amount in excess of one-ninth of
such number of Shares without the written consent of such Underwriter. If, on
the Closing Date, any Underwriter or Underwriters shall fail or refuse to
purchase Firm Shares and the aggregate number of Firm Shares with respect to
which such default occurs is more than one-tenth of the aggregate number of Firm
Shares to be purchased, and arrangements satisfactory to you, the Company and
the Selling Stockholders for the purchase of such Firm Shares are not made
within 36 hours after such default, this Agreement shall terminate without
liability on the part of any non-defaulting Underwriter, the Company or the
Selling Stockholders. In any such case either you or the relevant Sellers shall
have the right to postpone the Closing Date, but in no event for longer than
seven days, in order that the required changes, if any, in the Registration
Statement and in the Prospectus or in any other documents or arrangements may be
effected. If, on the Option Closing Date, any Underwriter or Underwriters shall
fail or refuse to purchase Additional Shares and the aggregate number of
Additional Shares with respect to which such default occurs is more than
one-tenth of the aggregate number of Additional Shares to be purchased, the
non-defaulting Underwriters shall have the option to (i) terminate their
obligation hereunder to purchase Additional Shares or (ii) purchase not less
than the number of Additional Shares that such non-defaulting Underwriters would
have been obligated to purchase in the absence of such default. Any action taken
under this paragraph shall not relieve any defaulting Underwriter from liability
in respect of any default of such Underwriter under this Agreement.

         If this Agreement shall be terminated by the Underwriters, or any of
them, because of any failure or refusal on the part of any Seller to comply with
the terms or to fulfill any of the conditions placed upon it in this Agreement,
or if for any reason any Seller shall be unable to perform its obligations under
this Agreement that are within its control, the Sellers will reimburse the
Underwriters or such Underwriters as have so terminated this Agreement with
respect to themselves, severally, for all out-of-pocket expenses (including the
fees and disbursements of their counsel) reasonably incurred by such
Underwriters in connection with this Agreement or the offering contemplated
hereunder.

         12. COUNTERPARTS. This Agreement may be signed in two or more
counterparts, each of which shall be an original, with the same effect as if the
signatures thereto and hereto were upon the same instrument.

         13. APPLICABLE LAW. This Agreement shall be governed by and construed
in accordance with the internal laws of the State of New York.

         14. HEADINGS. The headings of the sections of this Agreement have been
inserted for convenience of reference only and shall not be deemed a part of
this Agreement.

Ocular Sciences, Inc.

Gentlemen/Ladies:

        At your request, we have examined the Registration Statement on Form S-1
(the "Registration Statement") filed by you with the Securities and Exchange
Commission (the "Commission") on May 19, 1997 (Registration Number 333-27421),
Amendment No. 1 to such Registration Statement filed by you with the Commission
on June 4, 1997, Amendment No. 2 to such Registration Statement filed by you
with the Commission on July 2, 1997, Amendment No. 3 to such Registration
Statement filed by you with the Commission on July 15, 1997 and Amendment No. 4
to such Registration statement to be filed by you with the Commission on July
30, 1997 (collectively, the "Registration Statement") in connection with the
registration under the Securities Act of 1933, as amended, of an aggregate of
8,280,000 shares of your Common Stock (the "Stock"), up to 4,680,000 of which
are presently issued and outstanding and will be sold by certain selling
stockholders (the "Selling Stockholders").

        In rendering this opinion, we have examined the following:

        (1)   the Registration Statement, including exhibits;
        
        (2)   your registration statement on Form 8-A (File Number 000-22623)
              filed with the Commission on May 30, 1997;

        (3)   the prospectuses prepared in connection with the Registration
              Statement;

        (4)   the minutes of meetings and actions by written consent of the 
              stockholders and Board of Directors that are contained in your
              minute books of your predecessor, O.S.I. Corporation, a
              California corporation ("O.S.I. California"), that are in our
              possession.
             
        (5)   the stock records for both you and O.S.I. California that you
              have provided to us (consisting of a list of stockholders issued
              by you and a list of option holders respecting your capital stock
              that was prepared by you and dated the date hereof);

        (6)   the documentation relating to the acquisition of the shares to be
              sold by each Selling Shareholder pursuant to the Registration
              Statement; and

        (7)   a Management Certificate addressed to us and dated of even date
              herewith executed by the Company containing certain factual and
              other representations.

        In our examination of documents for purposes of this opinion, we have
assumed, and express no opinion as to, the genuineness of all signatures on
original documents, the authenticity of all documents submitted to us as
originals, the conformity to originals of all documents submitted to us as
copies, the legal capacity of all natural persons executing the same, the lack
of any undisclosed terminations, modifications, waivers or amendments to any
documents reviewed by us and the due execution and delivery of all documents
where due execution and delivery are prerequisites to the effectiveness thereof.

        As to matters of fact relevant to this opinion, we have relied solely
upon our examination of the documents referred to above and have assumed the
current accuracy and completeness of the information obtained from public
officials and records included in the documents referred to above. We have made
no independent investigation or other attempt to verify the accuracy of any such
information or to determine the existence or non-existence of any other factual
matters; however, we are not aware of any facts that would lead us to believe
that the opinion expressed herein is not accurate.

        Based upon the foregoing, it is our opinion that the up to 4,680,000
shares of Stock to be sold by the Selling Stockholders pursuant to the
Registration Statement are legally issued, fully paid and nonassessable and
that the 3,600,000 shares of Stock to be issued and sold by you, when issued and
sold in the manner referred to in the relevant prospectus associated with the
Registration Statement, will be legally issued, fully paid and nonassessable.

        We consent to the use of this opinion as an exhibit to the registration
Statement and further consent to all references to us in the Registration
Statement, the prospectus constituting a part thereof and any amendments
thereto.

        This opinion speaks only as of its date and is intended solely for the
your use as an exhibit to the Registration Statement for the purpose of the
above sale of the Stock and is not to be relied upon for any other purpose.


                                         Very Truly Yours,

          2.02 Exceptions.

that Section 8 of the Exchange Agreement, Section 11 of the Purchase and Supply
Agreement, Section 4 of the GH Galley and Morland Consulting Agreements and the
AD Galley Confidentiality and Invention Assignment Agreement contain
confidentiality obligations of some or all of the parties hereto. These

treat any information licensed hereunder (the "Licensed Information") in the
same manner as they treat their own confidential and/or proprietary information,
and will not disclose the same to third parties except for appropriate business
purposes, and only if such third party agrees in writing to maintain the
confidentiality of such information. The provisions of this Section 2.02 are
subject to the provisions of Section 13 hereof.

               (b)  OSL Rights to AG Work Product. The parties further
acknowledge that OSL has the right to use, disclose, copy and commercialize as
it sees fit any work product or information generated by ADG in his capacity as

shall instruct its attorneys to promptly take such actions as may be required or
appropriate to effectuate such dismissals with prejudice, including, without
limitation, filing of stipulations of dismissal in the form of Exhibits A-1,
A-2 and A-3, hereto within one business day. No orders or motions for costs or
damages will be sought or accepted by any party hereto against the other. All
interlocutory orders and judgments (draft or otherwise) will be of no further
force or effect.

     3.02 Release.

          (a)  Defendants' Release. Each of the Defendants, on behalf of itself
or himself, and on behalf of its or his respective agents, officers, directors,

acting by, through, under, or in concert with any of them, hereby releases and
forever discharges each of the Plaintiffs, and their respective agents,

actions or causes of action, in law or in equity, suits, debts, liens,
contracts, agreements, promises, liabilities, claims, demands, losses, damages,
costs, or expenses, whether or not now known, claimed or suspected, fixed or
contingent, which any of the Defendants now has, owns or holds, or at any time
heretofore had, owned or held or ever claimed to have had, owned or held or may
hereafter have, own or hold, based upon or arising from any matter, cause, fact,
thing, act or omission whatsoever occurring or existing at any time to and
including the date hereof, including, without limitation, the matters set forth
or which could have been set forth in the Actions, and matters arising from or
relating to the Defendants' capacity as shareholders of OSI, including, without
limitation, rights in derivative actions, provided, that this Release does not
release and discharge the Plaintiffs from their respective obligations,
agreements, acknowledgments, representations and warranties under this Agreement
or the exhibits hereto.

          (b)  Plaintiffs' Release. Each of the Plaintiffs, on behalf of itself
and himself, and on behalf of its and his respective agents, officers,
directors, employees, affiliates, predecessors and attorneys, and any persons or
entities acting by, through, under, or in concert with any of them, hereby
releases and forever discharges the Defendants, and their respective agents,
officers, directors, employees, affiliates, predecessors and attorneys, and any

including, without limitation, rights in derivative actions, provided, that this
Release does not release and discharge the Defendants from their respective
obligations, agreements, acknowledgments, representations and warranties under
this Agreement or the exhibits hereto.

          (c)  Waiver. Notwithstanding the choice of law provisions set forth
below, each of the parties understands and acknowledges that he or it is
familiar with California Civil Code Section 1542, which provides as follows:

                A general release does not extend to claims which the creditor
                does not know or suspect to exist in his favor at the time of
                executing the release, which if known by him must have
                materially affected his settlement with the debtor.

                                        3



<PAGE>   5


Each party expressly waives and relinquishes any rights it may have under Civil
Code Section 1542 or any other statute or common law principle with a similar
effect as to the releases set forth above. In connection with such release, each
of the parties acknowledges that he or it is aware that his or its attorneys or
agents may hereafter discover claims or facts in addition to or different from
those which he or it now knows or believes to exist, but that it is his or its
intention to hereby fully, finally and forever to settle and release all of the
disputes and differences, known or unknown, suspected or unsuspected, which now
exist, may exist, or heretofore have existed between the parties to this
Agreement, except as otherwise expressly provided herein. In furtherance of this
intention, the releases herein given shall be and remain in effect as full and
complete releases notwithstanding the discovery or existence of any such
additional or different claim of fact.

          3.03 Covenant Not to Sue or Instigate Action. The Defendants and
Plaintiffs each further agree not to institute, authorize, instigate or assist
in the institution of any administrative, legal or governmental proceeding
against the other, or the other's agents, officers, directors, employees,
affiliates, predecessors and attorneys, arising from or related to the matters
released above or any other matters arising on or before the date hereof, except
and only to the extent required by law, and hereby represent and warrant that
except for the Actions, as of the date hereof they have not so instituted,
authorized, instigated or assisted in any such proceedings.

          3.04 Irrevocable. The provisions of this Section 3 are irrevocable and
will not be affected by the breach or default of any other provision of this
Agreement; provided, however, that nothing herein shall limit any other rights
or remedies a party hereto may have on account of a breach or default of this
Agreement.

          3.05 No Admission of Liability. Nothing herein shall be construed as
an admission of liability by any party hereto, and the parties hereto
acknowledge that this Agreement is being entered into by the parties to avoid
the time and expense of further litigation.

          3.06 Exception. Nothing herein shall limit the parties future rights
and obligations under that certain Registration Rights Agreement dated October
30, 1992 and that certain Shareholders Agreement also dated October 30, 1992,
which agreements shall remain in full force and effect.

     4.   Payments to Defendants.

          4.01 Immediate Payment. Upon execution of this Agreement by each of
the parties hereto, OSL shall pay to the Defendants the sum of $3,333,333. Any
amounts due under this Section 4.01, and any amounts due under Section 4.02
below, may be paid by OSL to GHG on behalf of all Defendants.

          4.02 Deferred Payment. OSL shall also pay to the Defendants the
additional amount of $6,666.667. Such payment shall be made upon the earlier of
(i) the first anniversary hereof, (ii) the initial public offering of the Common
Stock of OSI or (iii) upon the acquisition of OSI in which the shareholders of
OSI prior to the transaction own less than a majority of the surviving
corporation. At the sole discretion of OSL, payment of up to $5 million of the
total may be made in Common Stock of OSI having an agreed upon value of $20 per
share, such that the number of shares issued in lieu of a cash payment of $5
million would be 250,000 shares. In the event that the Common Stock of OSI is
subject to any subdivision or amalgamation prior to

                                        4



<PAGE>   6


the issuance of such shares to the Defendants, then the number of shares issued
shall be increased or diminished so that the total value of the shares issued
equates to $5 million (or the applicable percentage thereof to be paid in stock)
based on the agreed upon value of $20 per presently existing share.

          4.03 OSI Guaranty. Payment of the amounts due under Sections 4.01 and
4.02 above, whether in cash or shares, is hereby unconditionally guaranteed by
OSI; provided, however, that this guaranty shall be subordinated to any
obligations of OSI to its lender, and the Defendants agree to enter into any
subordination agreement reasonably requested by such lender to effect the
foregoing. If OSL fails to make any payment due or issue any shares due within
three days after such is due, such obligation shall immediately become the
obligation of OSI. The transfer of the obligation to OSI shall not however
limit the Defendants' rights to take any action at law to secure such
outstanding payment from OSL as well as OSI unless and until such outstanding
obligation is paid in full. If the payment or shares due are not paid within 30
days of written notice of default by the Defendants to OSI, then the right to
make partial payment in shares shall terminate and all outstanding sums shall be
due in cash. Overdue amounts shall bear interest at the rate of prime plus 2%.

          4.04 Disclosure/Investment Representations. Each Defendant hereby
represents and warrants to OSI and OSL as follows:

               (a)  Such Defendant has had access to all information regarding
OSI, and its business, assets, liabilities and financial condition that such
Defendant reasonably considers important in agreeing to the $20 per share
valuation set forth above, and such Defendant has had ample opportunity to ask
questions of OSI's representatives concerning such matters. Without limiting the
foregoing, the Defendants agree to keep confidential any OSI financial
information provided to them pursuant to this Section 4.04(a), and to use such
information only for the purpose of valuing OSI shares.

               (b)  By reason of such Defendant's business or financial
experience, such Defendant is capable of evaluating the merits and risks of this
decision and has the ability to protect his or its own interests in this
transaction. Each Defendant expressly acknowledges that he or it is very
knowledgeable about the contact lens business. Such Defendant is making his or
its investment decision in this regard based solely on the Defendant's own
analysis of OSI, and such decision is not based on any representation, warranty
or statement made by OSI, OSL or any of its officers or directors.

              (c)  The Defendant understands and acknowledges that, in reliance
upon the representations and warranties made by the Defendants herein, any
shares issued to him or it will not be registered with the Securities and
Exchange Commission ("SEC") under the Securities Act of 1933, as amended (the
"Act"), or qualified under the California Corporate Securities Law of 1968, as
amended (the "Law"), but instead will be issued under an exemption or exemptions
from the registration and qualification requirements of such Act and Law, which
impose certain restrictions on the Defendants' ability to transfer the
certificates. Specifically, the Defendants understand that any shares issued to
them will not be transferable unless registered under the Act and qualified
under the Law, or unless an exemption from such registration or qualification is
available. The Defendants acknowledge that they will be acquiring any shares
issued to them pursuant to this Agreement for their own account for investment
purposes and not with a view to, or for sale in connection with, a distribution
of such shares within the meaning of

                                        5



<PAGE>   7
the Act. The Defendants agree to execute an appropriate investment
representation letter at the time that any shares are issued to them pursuant to
this Agreement, and understand that any such shares will be appropriately
legended to reflect the restrictions set forth herein.

               4.05 Mechanics of Payment. To the extent that cash is to be paid
hereunder, payment shall be made to the Defendants in pounds sterling, at the
spot dollar/sterling exchange rate published in the London Financial Times on
the date of payment. Payment in cash shall be made to such accounts, by wire
transfer or certified cheque drawn on a U.K. clearing bank, as OSL shall be
instructed in writing by GHG. Payment in stock shall be made by stock
certificates in such names as OSL shall be instructed in writing by GHG. The
Plaintiffs shall have no obligation or responsibility for the division of any
proceeds among the Defendants, and may rely entirely on instructions from GHG.

               4.06 No Setoff/Other Matters. With respect to payment hereunder,
time is of the essence in this Agreement and all due payments and/or issuance of
stock certificates in lieu of cash shall be made within three working days of
the due date. Payment shall be due notwithstanding any dispute of any nature
between the parties hereto whether related to this Agreement or any other
matter. OSL expressly accepts that it shall have no right to setoff in relation
to the payment to be made hereunder nor any cause whatsoever to withhold such
payment. Notwithstanding the foregoing, nothing herein shall limit any other
remedies OSL may have in the event of breach of this Agreement or otherwise.

               4.07 Taxes. The amounts set forth for payment to the Defendants
herein are pre-tax amounts. It is understood that the amounts actually to be
paid to the Defendants shall be net of any taxes to be withheld on account of
such payment. The parties agree that there will be 25% withholding on any
amounts paid by OSL hereunder, based on current law. The Defendants shall
provide OSL with any information reasonably requested by OSL to assist it to
determine the appropriate withholding amount. OSL shall provide the Defendants
with appropriate certification of any payments made to any taxing authority in
respect of such payments.

               4.08 Other Amounts. For the avoidance of doubt, the parties
hereby confirm that no further amounts are owed (i) by AVCL to OSL under the
Purchase and Supply Agreement or (ii) by OSL to the Patent Owners under the
Patent License Agreement. OSL shall be entitled to the return of the
approximately 768,000 pounds sterling held in escrow at Royal Bank of Scotland.

               4.09 Voting Trust. The parties acknowledge that, pursuant to
Section 8 hereof, the Patent Owners, OSI and Francis R. Tunney, Jr. are entering
into a Voting Trust Agreement. It is agreed that any shares issued pursuant to
Section 4.02 hereof shall be subject to such Voting Trust Agreement and that the
parties hereto will take any actions reasonably requested by OSI to implement
the foregoing.

     5.   Additional Payment to AVCL.

          5.01 Payment. OSL will pay to AVCL a commission of [ ]* in respect of
each and every lens which is a "Covered Product," as defined in Section 5.02
below, and which is sold by OSI or OSL, or their agents, during the three-year
period commencing 1 January 1997, to any branch or franchise retail outlet of
[ ]* operating in the United Kingdom. Such payment shall be made in respect of
each quarterly period commencing on 1 January 1997 within 60 days of the end
of each quarterly period, and shall be accompanied by a statement certified
by the

                                      
                                      6

  Commission.  Omitted portions have been filed separately with the Commission.

                                        



<PAGE>   8


Financial Director of OSL listing the number of Covered Products sold to
[ ]* in the United Kingdom in the quarterly period. OSL shall keep its
records regarding such information for at least three years after the end of the
relevant period. AVCL shall have the right, once per calendar year, upon 30 days
prior written notice to OSL and OSI, to review OSL's and OSI's books and records
regarding sales to [ ]* to verify the information provided to AVCL. Such
audit shall be at the expense of AVCL; provided, however, that if as a result of
such audit it is determined that the amounts owed to AVCL in any given quarter
were understated by more than 5%, then the cost of such audit shall be borne by
OSL. Upon the conclusion of any audit OSL shall pay to AVCL any amount underpaid
to AVCL, and AVCL shall pay to OSL any amount overpaid to AVCL. AVCL shall
maintain any information disclosed to them in confidence and shall not use such
information for any purpose other than verifying the amounts owed to them
hereunder.

          5.02 Covered Products. A "Covered Product" is any contact lens having,
or labelled or otherwise claimed in writing to have, the characteristics listed
on Exhibit B. A contact lens will not be considered a Covered Product if one or
more of the parameters of such contact lens is outside the variance listed below
relative to the parameters of Covered Products listed on Exhibit B.

               Lens Diameter                  [ ]* mm

               Lens Base Curve                [ ]* mm

               Lens Centre Thickness          [ ]* mm of nominal
                                              thickness [ ]* power, and
                                              normally incremented
                                              thickness throughout power
                                              range.

               Lens Water Content             [ ]*

A Covered Product that is manufactured from a material that incorporates an
ultra-violet inhibitor shall continue to be a Covered Product. Inclusion or
exclusion of a light handling tint will not affect whether a lens was considered
a Covered Product. If another company acquires OSI or OSL, or OSI or OSL
acquires another company, then the designs and brands of such other company will
not be considered Covered Products; provided, however, that if such company
sells OSI or OSL designs or brands, then such OSI or OSL designs or brands will
be considered Covered Products to the extent that they are within the designated
parameters.

     6.   Stock Ownership. Upon the signing hereof, OSI will deliver to the
Trustee under that certain Voting Trust Agreement (as defined in Section 8
below), for the benefit of the Patent Owners, share certificates for the shares
of OSI Common Stock to which the Patent Owners are entitled on account of OSI's
previous stock split. Separate certificates will be issued for the benefit of
each of the Patent Owners in the amounts set forth below:

     Patent Owner                           Number of Shares
     ------------                           ----------------

the Patent Owners and other shareholders of OSI will enter into an Amendment to
Registration Rights Agreement and Shareholder Agreement in the form attached
hereto as Exhibit C to provide certain priority registration rights to the
Patent Owners.

     8.   Voting Trust Agreement. Upon the signing hereof, the Patent Owners,
OSI and Francis R. Tunney, Jr., will enter into a Voting Trust Agreement in the
form attached hereto as Exhibit D. In connection therewith, the Patent Owners
will deliver to the Trustee all certificates held by them for shares of OSI
stock.

     9.   Patent License Agreement. Upon the signing hereof, the Patent Owners
and OSL will enter into a Patent License Agreement in the form attached hereto
as Exhibit E.

     10.  Return of Documentation and Media. Within 60 days of the signing
hereof, the parties will return to each other or destroy all documentation and
other media which belongs to the other parties hereto, including, without
limitation, documentation and other media discovered or otherwise obtained or
provided pursuant to the Actions, and each party warrants to the other that
within such 60 day period it will have returned or destroyed all documentation
and media of the other party in its possession and will not have taken or
retained any copies of such materials for future use. Notwithstanding the
foregoing, it is understood that AVCL may retain a copy of the documentation and
media to the extent that it is part of the Licensed Information. For the
avoidance of doubt, all documentation and media relating primarily to the
private affairs of ADG or the business of AVCL, and not materially related to
OSL's or OSI's business, which were removed from ADG's office at OSL Nursling
following termination of ADG's employment on 19th April 1994, shall be returned
to the respective owners. As to any documentation or media held by legal counsel
to the parties hereto, such may be returned by them, destroyed or retained by
them, provided that if they elect to retain such information they must agree in
writing to maintain the confidentiality of such information and not use such
information for any purpose (other than in connection with an arbitration of
this Agreement) or disclose such information to any person, including their
clients. For the avoidance of doubt, and notwithstanding any other provision
hereof, the Defendants and Plaintiffs each acknowledge that they do not have the
right to use and are not using information that was obtained from the other
after May 19, 1994, whether pursuant to the Actions or otherwise, except that
nothing herein limits the provisions of the Patent License Agreement.

     11.  Nondisparagement. The Plaintiffs hereby agree to not take any actions
to disparage the Defendants, and the Defendants hereby agree not to take any
actions to disparage the Plaintiffs, from and after the date hereof. AVCL, NFHC,
OSL and OSI shall instruct their respective employees, distributors and agents
to also not engage in any such disparagement. The foregoing shall not prevent
the parties hereto from competing with each other in good faith and in a
commercially reasonable manner.

     12.  Press Releases. OSI and AVCL may each issue a press release in the
forms attached hereto as Exhibits F-1 and F-2, respectively, within 15 days of
the signing of this Agreement. Except for such press releases, no party hereto
shall make any comment regarding


                                       8
<PAGE>   10


this settlement or the dispute or legal proceedings between them. Following the
earlier of (i) the conclusion of such 15-day period or (ii) the issuance of the
press releases, no further comments will be made by any party concerning the
settlement or the disputes or legal proceedings between them, and any inquiry
for further particulars shall be met with a reference to the above-mentioned
press releases with no further comment. Nothing herein limits the ability of the
parties to make necessary disclosures to professional advisors, potential
investors or acquirors and government regulatory agencies. Notwithstanding the
above, either party shall have the right to refute in detail any
misrepresentations of the outcome of the Actions which are made by either party
or its agents or distributors to customers or business associates of the other
party. Such refutation may be made to the customer or associate to whom the
misrepresentation has been made and/or to the person making the
misrepresentation. The parties reserve the right to take action against any
third party which continues to make such misrepresentations.

     13.  Confidentiality.

          13.01 Terms of Agreement. The parties hereto will keep the terms of
this Agreement confidential and will not disclose the same to any other persons
except for disclosures made in confidence to professional advisors, potential
investors or acquirors, and government regulatory agencies. Notwithstanding the
foregoing, each of the parties shall have the right to correct any material
misrepresentation of this Agreement made by the other party, or the other
party's agents or distributors, to customers or business associates of the first
party. Such correction may be communicated to the party making the
misrepresentation and the third party to whom such misrepresentation is made.
The parties reserve the right to take action against a third party which
continues to misrepresent the terms of this Agreement.

          13.02 Covered Products Confidentiality. Notwithstanding any other
provision hereof, including, without limitation, Section 2.02, the parties
hereto agree to keep confidential and not to release to others information
concerning the detail design, formulation and curing conditions of lenses that
are Covered Products, except that nothing herein shall limit the ability of OSI
and AVCL to disclose information to a company that has acquired them. The
Defendants and their successors will not assist any third party, directly or
indirectly, whether or not such party is licensed under the Licensed Patents, to
reproduce any of the Covered Products, and hereby represent to the Plaintiffs
that they have not previously done so, with the exception that the Defendants
have previously assisted [ ]* in the manufacture of its own [ ]* lens, which
is a Covered Product. Nothing herein shall preclude either party from
manufacturing and selling Covered Products or from publishing or otherwise
disseminating information relating to such Covered Product to the extent
normally undertaken by contact lens manufacturers and/or historically practiced
by OSI or AVCL in connection with the marketing of lenses.

          13.03 Covered Product Claims. The parties hereto shall not make any
claim that any Covered Product that they sell is the identical product or that
they are manufactured using the exact same technology as a product sold by the
other party. Nothing herein shall prevent the parties from disclosing
information relating to such Covered Products to the extent normally undertaken
by contact lens manufacturers and/or historically practiced by OSI or AVCL in
connection with the marketing of lenses.

          14.  Governing Law, Arbitration. All disputes arising from or related
to this Agreement, shall be resolved by binding arbitration. If the arbitration
is initiated by the Plaintiffs, then the arbitration shall be held in London,
England, shall be conducted by one or

more Queens Counsellors nominated by the London Common Law and Commercial Bar
Association, shall be governed by the law of England and Wales and shall be
conducted pursuant to the Rules of the London Court of International
Arbitration. If the arbitration is initiated by the Defendants, then the
arbitration shall be held in San Francisco, California, USA pursuant to the
Commercial Rules of Arbitration of the American Arbitration Association and
shall be governed by the laws of California. Any such arbitration shall be
conducted in a confidential manner. Notwithstanding the foregoing, the

                                    EXHIBIT D


                             VOTING TRUST AGREEMENT


        This Voting Trust Agreement (the "Agreement") is entered into and
effective as of February 27, 1997, by and among Geoffrey H. Galley, Anthony D.
Galley, Barrie Bevis, Albert H. Morland and Ivor Atkinson (collectively, the
"Shareholders"), Francis R. Tunney, Jr. as Trustee (Mr. Tunney, or any successor
Trustee appointed in accordance herewith, is referred to as the "Trustee"), and
O.S.I. Corporation, a California corporation (the "Company").

                                    RECITALS

        A.      The Shareholders are current shareholders of the Company and, in
the aggregate, hold 996,312 shares of the Company's Common Stock.

        B.      Pursuant to a Settlement Agreement and Release dated as of the
date hereof by and among the Shareholders, the Company and certain other
parties, the Shareholders have agreed to place all of their shares of the
Company's voting stock in a voting trust to be voted as set forth herein.

        In consideration of the mutual covenants herein contained, the
Shareholders, the Trustee and the Company agree as follows:

        1.      Purpose of Voting Trust. The purpose of this Voting Trust is to
ensure that, during the term of this Agreement, all votes, actions and consents
to be taken with respect to all shares of voting stock of the Company now owned,
or to be owned in the future, by the Shareholders shall be taken by the Trustee
on behalf of the Shareholders.

        2.      Transfer of Voting Stock to Trustee. Each of the Shareholders
shall, upon execution of this Agreement, duly endorse or cause to be endorsed in
blank the certificate or certificates representing all shares of the Company's
voting stock now owned (whether of record or beneficially) by such Shareholder,
and will deliver the same to the Trustee. Each Shareholder further agrees that,
during the term of this Agreement, such Shareholder will likewise immediately
endorse and deliver to the Trustee any and all certificates for additional
shares of the Company's voting stock that such Shareholder may hereafter
acquire. Shares of the Company's stock which the Shareholders are required to
deliver to the Trustee under this Section 2 shall be hereinafter collectively
referred to as the "Shares". Promptly upon receipt of such certificates, the
Trustee shall cause such Shares to be transferred in the name of the Trustee or
a nominee name designated by the Trustee on the Company's books and records, and
shall file a duplicate copy of this Agreement with the Secretary of the Company.
The failure by any Shareholder to deliver certificates for Shares to the Trustee
shall not affect or impair the trust created hereby or the rights of the Trustee
under this Agreement.



<PAGE>   28

        3.      Voting Trust Certificates.

                (a)     Issuance. Pursuant to Section 25102(f) of the California
Corporations Code and in reliance on the representations of each Shareholder in
Section 7 of this Agreement, the Trustee shall issue and deliver to each
Shareholder a Voting Trust Certificate (a "Certificate") representing the Shares
deposited with and held by the Trustee for the benefit of such Shareholder under
this Agreement. Such Certificates shall be in the form of Exhibit "A" hereto and
shall be signed by the Trustee.

                (b)     Certificate Book. The Trustee shall keep correct books
of account of all his business and transactions in his capacity as Trustee; and
shall also keep a book to be known as the Certificate Book, containing the names
of all persons who are Shareholders, showing their mailing addresses, the number
and type of Shares represented by the Certificates held by them and the date on
which they became the owner thereof.

                (c)     Legend. The Certificates shall be legended with all
legends with which the underlying Shares were required to be legended, together
with substantially the following legend:

        THE SHARES REPRESENTED BY THIS VOTING TRUST CERTIFICATE ARE
        SUBJECT TO THE TERMS AND CONDITIONS OF A VOTING TRUST
        AGREEMENT DATED FEBRUARY __, 1997, A COPY OF WHICH IS ON FILE
        AT THE PRINCIPAL OFFICE OF O.S.I. CORPORATION, AND THESE
        SHARES MAY NOT BE SOLD, PLEDGED, GIFTED, HYPOTHECATED OR
        OTHERWISE TRANSFERRED EXCEPT IN COMPLIANCE WITH THE TERMS AND
        CONDITIONS OF SUCH VOTING TRUST AGREEMENT.

                (d)     Lost Certificates. If a Certificate shall be lost,
stolen, mutilated or destroyed, the Trustee, in his discretion, may issue a
duplicate of such Certificate upon receipt of evidence of such loss satisfactory
to him and an indemnity agreement satisfactory to him, and upon receipt of the
existing Certificate, if mutilated. The Trustee may also require the holder of
such Certificate to pay fees and expenses as may be applicable to the reissuance
of a duplicate Certificate.

                (e)     Registered Owner. The Trustee may treat the registered
holder of each Certificate as the absolute owner thereof for all purposes
whatsoever, and accordingly shall not be required to recognize any legal,
equitable or other claim or interest in such Certificate on the part of any
other person, whether or not it or they shall have express or other notice
thereof.

                (f)     Transfer Procedures. A Certificate shall be transferable
on the books of the Trustee by the registered holder thereof, only to the extent
that the underlying Shares were transferable by the applicable Shareholder, in
person or by attorney-in-fact, and upon surrender of such Certificate duly
endorsed for assignment or accompanied by a duly executed instrument of
assignment, and upon payment of any transfer taxes or other charges in
connection with the transfer. All permitted transfers of Certificates shall be
recorded in the Certificate Book and any permitted transfer made of any
Certificate shall vest in the transferee all rights of the transferor, 

                                       2
<PAGE>   29

and shall subject the transferee to the same limitations as those imposed on the
transferor by the terms of the Certificate and this Agreement. Upon any such
permitted transfer, the Trustee shall deliver a Certificate to such transferee
representing the number of Shares represented by the Certificate so transferred.
Each permitted transferee of a Certificate shall be deemed to be a Shareholder
under this Agreement. If a transfer is to be made of less than all of the Shares
represented by a Certificate, the Trustee shall reissue to the transferor a
Certificate with respect to the Shares being retained by transferor.

                (g)     Securities Laws Compliance and Compliance with Other
Agreements. Neither the Shares nor the Certificates have been registered under
the Securities Act of 1933, as amended (the "Act") or registered or qualified
for resale under any applicable state law regulating securities. The
Certificates may not be offered, sold, transferred or hypothecated in the
absence of registration or the availability of an exemption from registration
under the Act and any applicable state law regulating securities. Each
Shareholder agrees not to sell, transfer, pledge or hypothecate such Certificate
unless the Trustee shall be reasonably satisfied that such sale or other
disposition does not violate the provisions of any agreement to which the
Shareholder is a party and unless either: (i) the transfer of the Certificate is
registered under the Act pursuant to a current and effective registration
statement at the time of such sale, transfer, pledge or hypothecation and is
registered or qualified under any applicable state law regulating securities; or
(ii) the Trustee has been furnished an opinion of counsel satisfactory in form
and substance to the Trustee that the Certificate may be so transferred or
disposed of without such registration or qualification. Each holder of
Certificate agrees that the Trustee may refuse to transfer any Certificate
except as aforesaid.

        4.      Acceptance of Trust. The Trustee, by executing this Agreement,
and each successor Trustee upon being appointed as such, accepts the voting
trust created hereby and agrees to carry out the terms and provisions hereof.

        5.      Trustees Rights, Powers, Duties and Expenses.

                (a)     Voting Rights. During the term of this Agreement, and
except as otherwise provided herein, the Trustee shall possess and shall be
entitled to exercise, with respect to the Shares, in person, or by his agent,
attorney-in-fact, or proxies, all voting rights and powers of absolute owners
and holders of such Shares, specifically including the right to vote, assent or
consent with respect thereto, and to take part in and consent to any corporate
or shareholder action of any kind whatsoever, whether by a vote at a meeting of
shareholders or by written consent, and to receive stock distributions with
respect to said Shares as provided in subsection 5(e) herein. In all such votes
the Trustee will vote the Shares in the same manner and same percentage as
Allergan, Inc., or any successor corporation ("Allergan") and Galen Partners,
L.P. and Galen Partners International, L.P., or any successor entity ("Galen")
vote their shares of the voting stock of the Company, in the aggregate. For
example, if Allergan and Galen, when taken together, vote 80% of their shares
for an issue and 20% against, then the Shares shall also be voted 80% for and
20% against. Notwithstanding anything to the contrary herein, the Trustee will
not vote the Shares in favor of any action that would materially and adversely
affect the rights of the Shareholders in a different manner than the other
Common Stock shareholders of the Company, as determined by the Trustee.

                                       3
<PAGE>   30

                (b)     Scope of Voting Rights. The right of the Trustee to
vote, assent or consent with respect to the Shares shall include, without
limitation, the right to vote at any election of directors, to vote on any
proposal to amend the articles of incorporation and/or by-laws of the Company,
to vote in favor of, or in opposition to, approval of any merger, consolidation,
dissolution, liquidation or reorganization of the Company and on any other
action of any character whatsoever which may be presented at any meeting or
require the consent of shareholders of the Company.

                (c)     No Right to Sell Shares. The Trustee shall have no
authority to sell, pledge, hypothecate, or otherwise dispose of any of the
Shares deposited pursuant to this Agreement.

                (d)     Permitted Activities. The Trustee and any firm,
corporation, trust, or association of which Trustee may be a trustee, owner,
member, shareholder, director, officer, agent, or employee may contract with or
may become financially interested in any matter or transaction to which the
Company or any subsidiary or controlled or affiliated corporation may be a party
or in which it may be concerned, as fully and freely as though such Trustee were
not a trustee hereunder. The Trustee may act as a director and/or officer of the
Company or of any subsidiary or controlled or affiliated corporation of the
Company, and may vote the Shares held hereunder in favor of his election as
such. The Shareholders acknowledge that the Trustee is currently a director of
the Company and the general counsel of Allergan, Inc., a major shareholder of
the Company.

                (e)     Notices, Dividends and Distributions.

                        (i)     Notices. The Trustee shall forward to each
Shareholder copies of all notices, reports, statements and other communications
received from the Company with respect to the Shares.

                        (ii)    Non-Stock Distributions. Each Shareholder shall
be entitled to receive payments equal to the amount of cash dividends, if any,
collected or received by the Trustee upon the number of Shares in respect of
which such Shareholder is the registered holder of a Certificate, less the
deductions provided for in subsection 5(e)(vi) below. Such payments shall be
made, as soon as practicable after the receipt of such dividends, to the
Certificate holders registered as such at the close of business on the record
date determined by the Company for such dividend. In his discretion, the Trustee
may arrange with the Company for the direct payment by the Company of dividends
to the registered Certificate holders.

                        (iii)   Stock Distributions. If the Trustee shall
receive, as a dividend or other distribution upon any Shares held by him under
this Agreement, any additional shares of the Company's stock having voting power
(as that term is defined in the California General Corporation Law), or
convertible into or exchangeable for securities having such voting power, the
Trustee shall hold the same subject to this Agreement in proportion to the
Shareholders' respective interests as shown on the books of the Trustee. The
Trustees shall issue Certificates with respect of such shares or other
securities to the Shareholders as their interests may appear.

                                       4
<PAGE>   31

                        (iv)    Dissolution of the Company. Notwithstanding
anything to the contrary herein, in the event that upon dissolution or total or
partial liquidation of the Company, whether voluntary or involuntary, the
Trustee shall receive the moneys, securities, rights or property to which the
holders of the Shares deposited hereunder are entitled, then the Trustee shall
distribute the same among the Shareholders in accordance with the terms of the
Company's Articles of Incorporation in proportion to the Shareholders'
respective interests as shown by the books of the Trustee, less the deductions
provided for in subsection 5(e)(vi) below, or the Trustee may in his discretion
deposit such moneys, securities, rights or property with any bank or trust
company with authority and instructions to distribute the same as above
provided, and upon such deposit all further obligations or liabilities of the
Trustee in respect of such moneys, securities, rights or property so deposited
shall cease.

                        (v)     Other Distributions. If the Trustee shall
receive or collect any moneys or property through a distribution by the Company
to its shareholders not covered by subsections 5(e)(ii), (iii) or (iv) hereof,
then the Trustee shall distribute the same to the Shareholders in proportion to
their respective interests as shown on the books of the Trustee, less the
deductions provided for in subsection 5(e)(vi) below.

                        (vi)    Withholdings. There shall be deducted and
withheld from every distribution under this Agreement any taxes, assessments,
and other amounts that may be required by law to be deducted or withheld.

                (f)     Use of Discretion; Limited Liability.

                        (i)     In voting, or otherwise acting hereunder with
respect to the Shares deposited hereunder, the Trustee shall be entitled to
exercise his own absolute discretion and judgment subject to the conditions
imposed by subsection 5(a) hereof; and neither the Trustee nor any of his agents
shall incur any responsibility or liability by reason of any error of law or
anything done or suffered or omitted, except for individual willful misconduct
or gross negligence. Neither the Trustee nor any of his agents shall be required
to give any bond or other security for the discharge of duties.

                        (ii)    Under no circumstances will the Trustee be
obligated to notify, confer with or seek the advice, consent, counsel, approval,
confirmation or ratification of the Shareholders with regard to any matter which
does or may be submitted to the shareholders of the Company for their approval.
The Trustee will not be liable to the Shareholders for any vote cast by the
Trustee in accordance with the terms of this Agreement.

                (g)     Expenses of Trustee. The Trustee may employ counsel, and
provide for such other assistance as may be convenient, in the performance of
his functions. The Company shall indemnify the Trustee against all expenses,
claims and liabilities incurred by him in connection with or arising out of this
Agreement for the discharge of his duties hereunder to the full extent permitted
by law. The Company shall, at the request of the Trustee, advance funds to pay
expenses incurred for legal or other assistance provided to the Trustee or for
legal fees or other expenses incurred by the Trustee in the defense of any
action, claim or proceeding arising as aforesaid.

                                       5
<PAGE>   32

                (h)     Construction of Agreement. The Trustee is authorized and
empowered to construe this Agreement, and his reasonable construction made in
good faith shall be conclusive and binding upon the Shareholders and upon all
parties hereto. The Trustee may consult with legal counsel, which may but need
not be counsel to the Company, and any action under this Agreement taken or
permitted in good faith by him in accordance with the opinion of such counsel
shall be conclusive upon the Shareholders and upon all parties hereto, and the
Trustee shall be fully protected and be subject to no liability with respect to
such action.

        6.      Rights of Shareholders. The Shareholders shall have rights in
the Certificates and in the Shares deposited in trust by such Shareholders
subject to the terms and provisions of this Agreement. Any heir, assignee or
transferee or person entitled to an interest in the rights of the Shareholders
to the Voting Trust Certificates or the Shares deposited by such Shareholders in
trust hereunder shall be subject to and bound by the provisions of this
Agreement.

        7.      Representations of Shareholders. Each Shareholder hereby
represents and warrants to the Trustee and the Company that:

                (a)     such Shareholder is acquiring the Certificate(s) for
such Shareholder's own account for investment purposes only and not with a view
to, or for sale in connection with, a distribution of the Certificate(s) within
the meaning of the Act;

                (b)     such Shareholder has had access to all information
regarding the Company and its present and prospective business, assets,
liabilities and financial condition that such Shareholder reasonably considers
important in making the decision to acquire the Certificate(s), and the
Shareholder has had ample opportunity to ask questions of the Company's
representatives concerning such matters and this acquisition;

                (c)     By reason of such Shareholder's business or financial
experience or the business or financial experience of such Shareholder's
professional advisors who are unaffiliated with and who are not compensated by
the Company or the Trustee, such Shareholder is capable of evaluating the merits
and risks of this investment and has the ability to protect such Shareholder's
own interests in this transaction; and

                (d)     such Shareholder understands and acknowledges that, in
reliance upon the representations and warranties made by such Shareholder
herein, the Certificate(s) are not being registered with the Securities and
Exchange Commission ("SEC") under the Act or being qualified under the
California Corporate Securities Law of 1968, as amended (the "Law"), but instead
are being issued under an exemption or exemptions from the registration and
qualification requirements of the Act and the Law which impose certain
restrictions on such Shareholder's ability to transfer the Certificate(s).

        8.      Successor Trustee. The Company and the Shareholders holding
Certificates representing a majority in interest in the Shares may at any time
jointly remove the Trustee from office and appoint a successor Trustee. The
Trustee may at any time resign by delivering to the Company his resignation in
writing, to be effective in accordance with its terms. Except as otherwise
provided herein, if the Trustee shall resign, or in the event of the death or
incapacity to


                                       6
<PAGE>   33

act of a Trustee, then a successor will be appointed jointly by the Company and
the Shareholders holding Certificates representing a majority in interest in the
Shares. If a successor Trustee has not been appointed within 30 days of the
resignation, removal or death of the current Trustee, then the successor Trustee
shall be William Grant.

        9.      Reorganization of Company. In case the Company is merged into or
consolidated with another corporation, then in connection with such transfer the
term "Company" for all purposes of this Agreement shall be taken to include such
successor corporation, and the Trustee shall receive and hold under this
Agreement the stock of such successor corporation received on account of the
ownership, as Trustee hereunder, of the stock held hereunder prior to such
merger or consolidation. Certificates issued and outstanding under this
Agreement at the time of such merger or consolidation may remain outstanding, or
the Trustee may, in his discretion, substitute for such Certificates new
Certificates in appropriate form, and the term "Shares" as used herein shall be
taken to include any stock which may be received by the Trustee in lieu of all
or any part of the Shares. Nothing herein shall limit the applicability of
Section 10(b)(ii) regarding the termination of this Agreement in the event of a
merger or consolidation meeting certain requirements.

        10.     Term and Termination.

                           (ii) EQUITY ISSUANCE AND SUBORDINATED DEBT PROCEEDS.

<PAGE>   29

                  Borrower or any of its Subsidiaries receives any Cash Proceeds
                  from any Equity Issuance or any issuance or sale of
                  Subordinated Debt that is permitted to be issued and sold upon
                  any waiver of the provisions of Section 5.3(d)(viii) by the
                  Lender (excluding any issuance of stock to employees of the
                  Borrower pursuant to a stock option plan), by an amount equal
                  to one hundred percent (100%) of all Cash Proceeds so
                  received, LESS all placement fees and underwriting expenses
                  paid in cash by the Borrower or such Subsidiary in connection
                  with such Equity Issuance or Subordinated Debt issuance or
                  sale; and

                           (iii) EXTRAORDINARY RECEIPTS. Whenever the Borrower
                  or any of its Subsidiaries receives any Cash Proceeds in any
                  extraordinary event outside of the ordinary course of business
                  (including insurance recoveries not reasonably and promptly
                  applied toward the repair or replacement of the damaged
                  property, but excluding (A) monies received by the Borrower or
                  any of its Subsidiaries in connection with the Galley
                  Litigation, (B) Cash Proceeds of any Asset Sale or Equity
                  Issuance covered by clauses (i) and (ii) above, (C) proceeds
                  of key man life insurance received under Section 5.2(g)(ii),
                  and (D) tax refunds and credits), by an amount equal to one
                  hundred percent (100%) of such receipts;

                  (e) NONSCHEDULED VOLUNTARY FACILITY PREPAYMENTS. The Borrower
         may prepay the outstanding principal amount of Advances under either
         Facility A or Facility B, or both, as the Borrower may elect, in whole
         or ratably in part, so long as (i) the Borrower gives two (2) Business
         Day's prior written notice to the Lender no later than 11:00 a.m.
         (Pacific time) (except that notices regarding Facility A prepayments
         may be given by no later than 11:00 a.m. (Pacific time) on the same day
         as the prepayment) stating (A) the proposed date of the prepayment, (B)
         the principal amount of the prepayment, (C) whether such prepayment
         will consist of Base Rate Advances or Eurodollar Rate Advances, and (D)
         whether such prepayment will consist of Facility A Advances or Facility
         B Advances, (ii) each partial prepayment is made in a principal amount
         of not less than $250,000 and integral multiples of $50,000 in excess
         thereof, (iii) if any Eurodollar Rate Advance is paid prior to the last
         day of the Interest Period for such Advance, all unpaid interest
         accrued to the date of prepayment on the principal amount prepaid and
         all Breakage Costs incurred as a result of the prepayment are also
         paid, and (iv) all unpaid interest under Facility B accrued to the date
         of prepayment is paid concurrently with any prepayment in full. Notice
         of prepayment, once given, shall be irrevocable, and the amount of the
         prepayment specified in the notice shall accordingly be due and payable
         on the prepayment date specified therein. Prepayments under Facility A
         may be reborrowed on the terms and conditions set forth herein;
         prepayments under Facility B may not be reborrowed.

<PAGE>   30

                  (f) APPLICATION OF NONSCHEDULED FACILITY B PREPAYMENTS. All
         mandatory prepayments of Facility B shall be credited to the future
         scheduled Facility B payments in the inverse order of maturity. All
         voluntary prepayments of Facility B shall be credited to the future
         scheduled Facility B payments in the order of maturity or as the
         Borrower may otherwise direct. All Facility B prepayments whether
         mandatory or voluntary shall automatically and permanently reduce the
         Facility B Amount by the amount so credited.

                  (g) OPTIONAL REDUCTION OR TERMINATION OF FACILITY A. The
         Borrower may permanently reduce the Facility A Amount, in whole or in
         part or terminate Facility A, upon at least five (5) Business Days'
         prior written notice to the Lender; PROVIDED that (i) each partial
         reduction of the Facility A Amount shall be in an aggregate principal
         amount of $1,000,000 or an integral multiple of $100,000 in excess
         thereof; (ii) each reduction or termination shall be accompanied by the
         payment of the commitment fee, if any, accrued on the Facility A Amount
         so reduced through the date of such reduction or termination; (iii) the
         Facility A Amount, as so reduced, shall not be less than the sum of the
         aggregate Facility A Advances then outstanding plus the Letter of
         Credit Usage then outstanding; (iv) the Borrower shall prepay the
         amount, if any, by which the sum of the aggregate Facility A Advances
         then outstanding plus the Letter of Credit Usage then outstanding
         exceeds the Facility A Amount as so reduced, together with interest
         thereon to the date of prepayment; and (v) if the termination or
         reduction of the Facility A Amount requires the prepayment of
         Eurodollar Rate Advances, the termination or reduction may be made only
         on the last Business Day of the then current Interest Period applicable
         to such Eurodollar Rate Advance.

                  (h) EXCESS EXPOSURE. If at any time for any reason, the
         aggregate outstanding Facility A Advances PLUS the outstanding Letter
         of Credit Usage exceed the Facility A Availability then in effect, the
         Borrower shall immediately, without notice or demand, repay Facility A
         Advances in an amount equal to such excess.

                  (i) CHANGE OF CONTROL. The Borrower shall give the Lender
         written notice of a Change of Control twenty (20) Business Days prior
         to a Change of Control (or if twenty (20) Business Days' notice is not
         practicable, such lesser notice (but not less than five (5) Business
         Days) as is practicable). On the date of a Change of Control (i) all
         Advances then outstanding shall be due and payable in full, (ii) the
         Borrower shall deposit with the Lender cash collateral (in a form
         acceptable to the Lender) in an amount equal to the Letter of Credit
         Usage then outstanding, and (iii) the Facility Amount shall be
         automatically and permanently reduced to zero.

                  (j) PREPAYMENT FEE. The foregoing notwithstanding, if the
         Borrower prepays all Advances then outstanding, and terminates Facility
         A (or the Facility A Amount is permanently reduced to zero) in
         connection with a Change of Control or with the proceeds of Debt (other
         than Debt borrowed from the Lender), then the Borrower shall pay to the
         Lender in addition to the amounts otherwise described herein, a fee
         equal to (i) two percent (2%) of the principal amount of the Advances
         prepaid, if such amounts are



                                       23
<PAGE>   31

         prepaid after the Closing Date through and including the first
         anniversary of the Closing Date, or (ii) one percent (1%) of the
         principal amount of the Advances prepaid, if such amounts are prepaid
         from but excluding the date of the first anniversary of the Closing
         Date through and including the date of the second anniversary of the
         Closing Date. The Borrower and the Lender agree that damages for the
         prepayment set forth herein are difficult to ascertain and that such
         prepayment fee is not and shall not be deemed to be a penalty, but an
         agreed upon reasonable amount of liquidated damages.

                  SECTION II.6. INTEREST. The Borrower agrees to pay interest on
the unpaid principal amount of each Advance made by the Lender from the date of
such Advance until such principal amount shall be repaid in full, at the
following rates per annum:

                  (a) BASE RATE ADVANCES. Whenever such Advance is a Base Rate
         Advance, a rate per annum equal on each day to the Base Rate as in
         effect on such day PLUS the applicable Interest Margin, with all such
         interest payable quarterly in arrears on the last day of each January,
         April, July and October (commencing January 31, 1997) and, with respect
         to the Facility A Advances, on the Facility A Maturity Date and, with
         respect to the Facility B Advance, such other date that such Advance is
         repaid, or required to be repaid, in full.

                  (b) EURODOLLAR RATE ADVANCES. Whenever such Advance is a
         Eurodollar Rate Advance, a rate per annum equal on each day during the
         Interest Period for such Eurodollar Rate Advance to the sum of the
         Eurodollar Rate for such Interest Period determined for such day PLUS
         the applicable Interest Margin, with all interest so accrued payable on
         the last day of such Interest Period and, if such Interest Period has a
         duration of more than three months, on the day which occurs three
         months after the first day of such Interest Period.

                  (c) DEFAULT INTEREST. From and after the occurrence of an
         Event of Default, all amounts outstanding under this Agreement, to the
         extent permitted by law, will bear interest equal to the greater of (i)
         the rate applicable to Base Rate Advances PLUS three percent (3%) per
         annum or (ii) the rate otherwise payable on such amount (without giving
         effect to this provision) PLUS three percent (3%) per annum.

                  SECTION II.7. INTEREST RATE DETERMINATION AND PROTECTION.

                  (a) DETERMINATION OF EURODOLLAR RATE. The Eurodollar Rate for
         each Interest Period for Eurodollar Rate Advances shall be determined
         by the Lender at or before 11:00 am (Pacific time) two (2) Business
         Days before the first day of such Interest Period.

                  (b) NOTICE OF EURODOLLAR RATE. The Lender shall give prompt
         notice to the Borrower of the Eurodollar Rate for any Interest Period
         when determined by the Lender.



                                       24
<PAGE>   32

                  (c) SUSPENSION OF EURODOLLAR RATE ADVANCES. If, with respect
         to any Eurodollar Rate Advance, the Lender determines that, by reason
         of circumstances affecting the foreign exchange and interbank markets
         generally, either (i) the Eurodollar Rate for any Interest Period for
         such Eurodollar Rate Advance is insufficient to cover the cost to the
         Lender of obtaining deposits in eurodollars in an amount substantially
         equal to the Eurodollar Rate Advance and for a period equal to such
         Interest Period or (ii) deposits are not available to the Lender in
         such market in eurodollars, then the Lender shall forthwith so notify
         the Borrower and thereupon (A) each Eurodollar Rate Advance will
         automatically, on the last day of the then existing Interest Period
         therefor, convert into a Base Rate Advance, and (B) the obligation of
         the Lender to make or continue, or to convert Advances into, Eurodollar
         Rate Advances shall be suspended until the Lender shall notify the
         Borrower that the circumstances causing such suspension no longer
         exist.

                  (d) FAILURE TO SPECIFY DURATION. If the Borrower fails, prior
         to the date the Eurodollar Rate for any Interest Period is determined
         by the Lender, to specify the duration of any Interest Period for any
         Eurodollar Rate Advances, the Interest Period shall be one month.

                  (e) MINIMUM AMOUNTS. No Borrowing of LESS than $1,000,000 may
         be made or continued as, or converted into, Eurodollar Rate Advances.
         If at any time the aggregate outstanding principal amount of all
         Eurodollar Rate Advances having the same Interest Period is reduced to
         less than $1,000,000, such Advances shall automatically and immediately
         convert into Base Rate Advances.

                  (f) LENDER'S DETERMINATION CONCLUSIVE. Each determination by
         the Lender of an interest rate hereunder shall be conclusive and
         binding for all purposes, absent manifest error.

                  SECTION II.8. VOLUNTARY CONVERSION OF ADVANCES.

                  (a) NOTICE OF CONVERSION/CONTINUATION. Subject to the
         provisions of Sections 2.7 and 2.11, the Borrower may on any Business
         Day, by giving the Lender a Notice of Continuance/Conversion not later
         than 11:00 a.m. (Pacific time) on the second preceding Business Day,
         (i) convert Base Rate Advances into Eurodollar Rate Advances, (ii)
         convert Eurodollar Rate Advances into Base Rate Advances or (iii)
         continue Eurodollar Rate Advances as Eurodollar Rate Advances, but (A)
         the Borrower may convert a Eurodollar Rate Advance into a Base Rate
         Advance only on the last day of an Interest Period for such Eurodollar
         Rate Advance, (B) the Borrower may continue a Eurodollar Rate Advance
         as a Eurodollar Rate Advance only as of the last day of an Interest
         Period for such Eurodollar Rate Advance, and (C) no Advance may be
         converted into or continued as a Eurodollar Rate Advance at any time
         when an Event of Default or Potential Default has occurred and is
         continuing.

                  (b) TELEPHONIC NOTICE. In lieu of delivering a Notice of



                                       25
<PAGE>   33

         Continuance/Conversion, the Borrower may give the Lender telephonic
         notice of any proposed conversion or continuance by the time required
         under Section 2.8(a) and in such event shall promptly (but in no event
         later than 5:00 p.m. (Pacific time) on the second Business Day prior to
         the date of the requested conversion or continuance) deliver a
         confirmatory written Notice of Continuance/Conversion to the Lender. If
         the telephonic request differs in any respect from the written Notice
         of Continuance/Conversion subsequently furnished, the telephonic
         request shall govern as to the terms of such notice. The Lender's
         determination of the contents of any telephonic request shall, absent
         manifest error, be conclusive and binding on all parties hereto.

                  (c) REQUIREMENTS. Each Notice of Continuance/Conversion or
         telephonic request shall specify (i) the date of the continuance or
         conversion, (ii) whether such Advance is a continuance or conversion of
         an outstanding Advance, (iii) the aggregate principal amount of the
         Advance to be converted or continued, (iv) whether such Advance is a
         Facility A Advance or the Facility B Advance, and (v) when such Advance
         is converted into or continued as a Eurodollar Rate Advance, the
         duration of the Interest Period for such Advance.

                  (d) BASE RATE ADVANCES. Unless a Eurodollar Rate has been
         determined for a particular Advance and applies to such Advance on a
         particular day in accordance with the provisions hereof, such Advance
         shall be a Base Rate Advance and shall accrue interest at the rate then
         applicable to Base Rate Advances.

                  SECTION II.9. FUNDING LOSSES. If (i) any Eurodollar Rate
Advance is repaid or converted to a Base Rate Advance on any day other than the
last day of an Interest Period for such Eurodollar Rate Advance (whether as a
result of any optional prepayment, mandatory prepayment, payment upon
acceleration, mandatory conversion or otherwise), (ii) the Borrower fails to
borrow any Eurodollar Rate Advance in accordance with a Notice of Borrowing or a
telephonic request delivered to the Lender (whether as a result of the failure
to satisfy any applicable conditions or otherwise), (iii) any Base Rate Advance
is not converted into a Eurodollar Rate Advance or any Eurodollar Rate Advance
is not continued as a Eurodollar Rate Advance in accordance with a Notice of
Continuance/Conversion or telephonic request delivered to the Lender (whether as
a result of the failure to satisfy any applicable conditions or otherwise), or
(iv) the Borrower fails to make any prepayment in accordance with any notice of
prepayment delivered to the Lender, the Borrower shall, upon demand by the
Lender, reimburse the Lender for all reasonable costs and losses incurred by the
Lender as a result of such repayment, prepayment or failure ("Breakage Costs"),
including reasonable costs and losses incurred by the Lender as a result of
funding arrangements or contracts entered into by the Lender to fund Eurodollar
Rate Advances. Breakage Costs shall be payable only if demanded within ninety
(90) days after the end of the applicable Interest Period and shall be due
thirty (30) days after demand. Demand shall be made by delivery to the Borrower
of a certificate making the demand, setting forth in reasonable detail the
calculation of the Breakage Costs for which demand is made. Such certificate
shall, in the absence of manifest error, be conclusive and binding on the
Borrower. The calculation of any amounts payable to the Lender shall be made as
though the Lender shall



                                       26
<PAGE>   34

have actually funded or committed to fund the relevant Eurodollar Rate Advance
through the purchase of an underlying deposit in an amount equal to such
Eurodollar Rate Advance and having a maturity comparable to the relevant
Interest Period; PROVIDED that the Lender may fund any Eurodollar Rate Advance
in any manner it deems fit and the foregoing assumptions shall be utilized only
for the purpose of the calculation of amounts payable under this paragraph. If
the Borrower shall be obligated to repay Eurodollar Rate Advances pursuant to
Section 2.5(d) or Section 2.11 on a date that is not the last day of the
Interest Period for such Eurodollar Rate Advances, then the Borrower may, in
lieu of making such payment on such date in order to avoid the obligation to pay
Breakage Costs, deposit Dollars with the Lender in an amount equal to the amount
of the Eurodollar Rate Advances being repaid plus interest to the date such
prepayment will be applied. Such deposit shall (A) be held by the Lender on
terms and conditions satisfactory to the Lender in its sole discretion and (B)
be applied by the Lender to such Eurodollar Rate Advances on the last day of the
Interest Period therefor.

                  SECTION II.10. INCREASED COSTS.

                  (a) INCREASE IN COST. If, due to either (i) the introduction
         of or any change in or in the interpretation of any law or regulation
         after the Closing Date or (ii) the compliance with any guideline or
         request from any central bank or other Governmental Authority (whether
         or not having the force of law) made after the Closing Date, there
         shall be any increase in the cost to the Lender of agreeing to make or
         making, funding or maintaining Eurodollar Rate Advances, then the
         Borrower shall from time to time pay to the Lender, additional amounts
         sufficient to compensate the Lender or participant for such increased
         cost. Such costs shall be payable only if demanded within six (6)
         months after they were incurred and shall be due thirty (30) days after
         demand. Demand shall be made by delivery to the Borrower of a
         certificate of the Lender, setting forth in reasonable detail the
         calculation of the costs for which demand is made. Such certificate
         shall, in the absence of manifest error, be conclusive and binding on
         the Borrower.

                  (b) INCREASE IN CAPITAL REQUIREMENTS. If the Lender determines
         that compliance with any change in law or regulation or any guideline
         or request from any central bank or other Governmental Authority
         (whether or not having the force of law), in each case after the
         Closing Date, affects or would affect the amount of capital required or
         expected to be maintained by the Lender or any corporation controlling
         the Lender and that the amount of such capital is increased by or based
         upon the existence of the Lender's commitment to lend or funding
         hereunder and other commitments or funding of this type, then, upon
         demand by the Lender, the Borrower shall, within thirty (30) days after
         demand from time to time by the Lender, pay to the Lender, additional
         amounts sufficient to compensate the Lender in the light of such
         circumstances, to the extent that the Lender determines in good faith
         that such increase in capital to be allocable to the existence of the
         Lender's commitment to lend or funding hereunder. No such compensation
         may be demanded as to increased capital maintained by the Lender more
         than six (6) months before compensation was first demanded by the
         Lender under this Section 2.10(b). Demand for such compensation shall
         be made by delivery to the Borrower of a certificate



                                       27
<PAGE>   35

         of the Lender setting forth the amount demanded. Such certificate
         shall, in the absence of manifest error, be conclusive and binding on
         the Borrower.

                  SECTION II.11. ILLEGALITY. Notwithstanding any other provision
of this Agreement, if the Lender shall notify the Borrower that the introduction
of or any change in or in the interpretation of any law or regulation makes it
unlawful, or any central bank or other Governmental Authority asserts that it is
unlawful, for the Lender to perform its obligations hereunder to make Eurodollar
Rate Advances or to fund or maintain Eurodollar Rate Advances hereunder, then
(i) the obligation of the Lender to make or continue, or to convert Advances
into, Eurodollar Rate Advances shall be suspended until the Lender shall notify
the Borrower that the circumstances causing such suspension no longer exist, and
(ii) the Borrower shall forthwith either (A) prepay in full all Eurodollar Rate
Advances of the Lender then outstanding, together with interest accrued thereon
and Breakage Costs related thereto, or (B) convert all Eurodollar Rate Advances
of the Lender then outstanding into Base Rate Advances and pay all interest
accrued thereon to the date of conversion and all Breakage Costs related
thereto.

                  SECTION II.12. PAYMENTS AND COMPUTATIONS.

                  (a) PAYMENTS. The Borrower shall make each payment due
         hereunder not later than 2:00 p.m. (Pacific time) on the day payment is
         due, in Dollars received by the Lender at its address referred to in
         Section 7.2 in same day funds.

                  (b) COMPUTATIONS. Except as otherwise specified in Section
         2.16(a), all computations of interest and fees accruing at a per annum
         rate shall be made on the basis of the actual number of days (including
         the first day but excluding the last day) occurring in the period for
         which such interest or fees are payable and a year of three hundred
         sixty (360) days.

                  (c) PAYMENT ON BUSINESS DAY. Whenever any payment hereunder is
         due on a day other than a Business Day, such payment shall be made on
         the next succeeding Business Day, and such extension of time shall be
         included in the computation of interest or fees. If, however, such
         extension would cause payment of interest on or principal of Eurodollar
         Rate Advances to be made in the next following calendar month, such
         payment shall be made on the next preceding Business Day.

                  SECTION II.13. TAXES.

                  (a) NET PAYMENTS. Any and all payments by the Borrower
         hereunder shall be made free and clear of, and without deduction for,
         any and all present or future taxes, levies, imposts, deductions,
         charges or withholdings, and all liabilities with respect thereto,
         excluding, in the case of the Lender, taxes imposed on its net income,
         and franchise taxes imposed on it, by the jurisdiction under the laws
         of which the Lender is organized or any municipal subdivision thereof
         (all such non-excluded taxes, levies, imposts, deductions, charges,
         withholdings and liabilities, collectively, are "Taxes"). If the
         Borrower is required by law to deduct any Taxes from or in respect of
         any sum payable hereunder to the Lender, (i) the sum payable shall be
         increased as may be necessary so that after making all required
         deductions (including deductions applicable to additional sums payable
         under this Section 2.13) the Lender receives an amount equal to the sum
         it would have received if no such deductions had been made, (ii) the
         Borrower shall make such deductions, and (iii) the Borrower shall pay
         the full amount deducted to the relevant taxation authority or other
         authority in accordance with applicable law.

                  (b) PAYMENT OF OTHER TAXES. In addition, the Borrower agrees
         to pay any present or future stamp or documentary taxes or any other
         excise or property taxes, charges or similar levies which arise from
         any payment made hereunder or under or from the execution, delivery or
         registration of, or otherwise with respect to, this Agreement or any
         other Loan Document ("Other Taxes").

                  (c) INDEMNIFICATION. The Borrower will indemnify the Lender
         for the full amount of Taxes or Other Taxes (including any Taxes or
         Other Taxes imposed by any jurisdiction on amounts payable under this
         Section 2.13) paid by the Lender and any liability (including
         penalties, interest and expenses) arising therefrom or with respect
         thereto. Payment under this indemnity shall be due thirty (30) days
         after written demand therefor.

                  (d) EVIDENCE OF PAYMENTS. Within thirty (30) days after the
         date of any payment of Taxes, the Borrower will furnish to the Lender,
         at its address referred to in Section 7.2, the original or a certified
         copy of a receipt evidencing payment thereof. If no Taxes are payable
         in respect of any payment hereunder, the Borrower will furnish to the
         Lender, at such address, a certificate from each appropriate taxing
         authority, or an opinion of counsel acceptable to the Lender, in either
         case stating that such payment is exempt from or not subject to Taxes.

                  SECTION II.14. ISSUANCE OF LETTERS OF CREDIT. Upon the request
of the Borrower, and subject to the conditions set forth in Article III hereof
and such other conditions to the opening of Letters of Credit as the Lender
requires of its customers generally, the Lender shall from time to time open
standby and/or documentary (commercial) letters of credit (each, a "Letter of
Credit") for the account of the Borrower; PROVIDED, HOWEVER, that the Letter of
Credit Usage shall not at any time exceed $3,000,000; and PROVIDED, FURTHER,
that no Letter of Credit



                                       29
<PAGE>   37

shall be opened if at such time the sum of the Letter of Credit Usage then
outstanding (after giving effect to the proposed new Letter of Credit) plus the
aggregate Facility A Advances then outstanding shall exceed the lesser of the
Facility A Amount or the Borrowing Base at such time. The issuance of each
Letter of Credit shall be made on at least five (5) Business Days' prior written
notice from the Borrower to the Lender which written notice shall be an
application for a Letter of Credit on the Lender's customary form completed to
the satisfaction of the Lender, together with the proposed form of the Letter of
Credit (which shall be denominated in Dollars and require drafts payable at
sight and otherwise be satisfactory to the Lender) and such other certificates,
documents and other papers and information as the Lender may reasonably request.
The Lender shall not at any time be obligated to issue any Letter of Credit if
such issuance would conflict with, or cause the Lender to exceed any limits
imposed by, any applicable requirements of law. The expiration date of any
standby Letter of Credit shall not be later than three hundred sixty (360) days
from the date of issuance thereof or such later date to which a Letter of Credit
expiration date may be extended by the application of automatic extension or
"evergreen" provisions of such Letter of Credit and the expiration date of any
documentary (commercial) Letter of Credit shall not be later than one hundred
eighty (180) days from the date of issuance thereof; PROVIDED, HOWEVER, that in
no event shall any Letter of Credit shall have an expiration date later than the
Facility A Maturity Date. The Letters of Credit shall be issued with respect of
transactions occurring in the ordinary course of business of the Borrower.

                  SECTION II.15. PAYMENT OF LETTERS OF CREDIT; REIMBURSEMENT. 
The Lender shall review each draft and any accompanying documents presented
under a Letter of Credit. Promptly after the Lender shall have ascertained that
any draft and any accompanying documents presented under such Letter of Credit
appear on their face to be in substantial conformity with the terms and
conditions of the Letter of Credit, (i) the Lender shall, not later than 11:00
a.m. (Pacific time) on the date payment under the Letter of Credit is to be
made, give telephonic or facsimile notice to the Borrower of the receipt and
amount of such draft and the date on which payment thereon will be made, and
(ii) the Lender shall, not later than 2:00 p.m. (Pacific time) on such day, make
the appropriate payment to the beneficiary of such Letter of Credit, and (iii)
the Borrower shall, not later than 2:00 p.m. (Pacific time) on such date,
reimburse the Lender for such payment (such reimbursement may be in the form of
an Advance under Facility A, if the Borrower meets all of the conditions
precedent for such an Advance and complies with the requirements of Section
2.1). If the Borrower does not reimburse the Lender within the time set forth
above, then the Borrower shall pay to the Lender (in addition to the amount of
the drawing) interest on such amount at a rate per annum equal to the rate
applicable to Base Rate Advances hereunder PLUS three percent (3%), payable on
demand. The obligations of the Borrower under this Section 2.15 to reimburse the
Lender for all drawings under Letters of Credit shall be absolute, unconditional
and irrevocable and shall be satisfied strictly in accordance with their terms,
irrespective of:

                  (A) any lack of validity or enforceability of any Letter of
Credit;

                  (B) the existence of any claim, setoff, defense or other right
which the Borrower or any other Person may at any time have against the
beneficiary under any Letter of



                                       30
<PAGE>   38

Credit or the Lender (other than the defense of payment in accordance with the
terms of this Agreement or a defense based on the gross negligence or willful
misconduct of the Lender) or any other Person in connection with this Agreement
or any other transaction;

                  (C) any draft or other document presented under any Letter of
Credit proving to be forged, fraudulent, invalid or insufficient in any respect
or any statement therein being untrue or inaccurate in any respect;

                  (D) payment by the Lender under any Letter of Credit against
presentation of a draft or other document which does not comply with the terms
of such Letter of Credit; and

                  (E) any other circumstance or event whatsoever, whether or not
similar to any of the foregoing.

         It is understood that in making any payment under any Letter of Credit
(x) the Lender's exclusive reliance on the documents presented to it under such
Letter of Credit as to any and all matters set forth therein, including, without
limitation, reliance on the amount of any draft presented under such Letter of
Credit, whether or not the amount due to the beneficiary equals the amount of
such draft and whether or not any document presented pursuant to such Letter of
Credit proves to be insufficient in any respect, if such document on its face
appears to be in order, and whether or not any other statement or any other
document presented pursuant to such Letter of Credit proves to be forged or
invalid or any statement therein proves to be inaccurate or untrue in any
respect whatsoever, and (y) any noncompliance in any immaterial respect of the
documents presented under such Letter of Credit with the terms thereof shall, in
each case, not be deemed willful misconduct or gross negligence of the Lender.

                  SECTION II.16. LETTER OF CREDIT FEES.

                  (a) The Borrower agrees to pay to the Lender with respect to
each standby Letter of Credit, an issuance fee equal to the then effective per
annum Interest Margin applicable to Eurodollar Rate Advances multiplied by the
face amount of such Letter of Credit for the period from and including the date
of issuance to and including the stated expiry date, payable prior to issuance
of such Letter of Credit.

                  (b) The Borrower agrees to pay to the Lender with respect to
each documentary (commercial) Letter of Credit, an issuance fee at the rate
customarily charged by the Lender at the time in like circumstances, payable
prior to issuance of such Letter of Credit.

                  (c) The Borrower agrees to pay to the Lender on demand, such
other commissions, negotiation fees, transfer fees, and other fees, charges and
expenses in connection with the issuance, amendment, transfer, cancellation,
handling or administration of each Letter of Credit which are customarily
charged by the Lender at the time in connection with such matters.

                  (d) Any fees paid pursuant to this Section 2.16 are
non-refundable.

         organized and is duly qualified to do business and in good standing in
         each jurisdiction where its material assets are located or its material
         operations are conducted, except where the failure to be so qualified
         could not reasonably be expected to cause a Material Adverse Change.

                  (b) POWER AND AUTHORITY. Each Loan Party has the corporate or
         partnership power (i) to carry on its business as now being conducted
         and as proposed to be conducted by it, (ii) to execute, deliver and

                  (c) DUE AUTHORIZATION. The execution, delivery and performance
         by each Loan Party of each Loan Document to which it is or will be a
         party have been duly authorized by all necessary action of its board of
         directors (or, in case of a Loan Party that is not a corporation,

         Documents) upon any of its property or assets.

                  (d) SUBSIDIARIES AND OWNERSHIP OF CAPITAL STOCK. Set forth in
         Schedule 4.1(d) or in Schedule A to the Borrower Pledge and Security
         Agreement, as such Schedule may be amended pursuant to Section 5.2(e),
         or in Schedule A to the Subsidiary Pledge and Security Agreement, as
         such Schedule may be amended pursuant to Section 5.2(e), is a complete
         list of all direct and indirect Subsidiaries of the Borrower. Such
         Schedules also set forth the number of issued and authorized shares of
         each class of capital stock of and other equity, ownership or profit
         interests in such Subsidiary and the identity of the holders of all
         such shares. Except as set forth in such Schedules, no capital stock of
         or other equity, ownership or profit interest in any such Subsidiary is
         subject to issuance or sale under any warrant, option or purchase
         right, conversion or exchange right, call, commitment or claim of any
         right, title or interest therein or thereto. The outstanding capital
         stock of each such Subsidiary is duly authorized, validly issued, fully
         paid and nonassessable and, is not "margin stock," as that term is
         defined in Regulations G, T, U and X of the Board of Governors of the
         Federal Reserve System.

                  (e) GOVERNMENTAL APPROVAL. No authorization or approval or
         other action by, and no notice to or filing with, any Governmental
         Authority is required for the due execution, delivery and performance
         by each of the Loan Parties of any Loan Document to which it is or will
         be a party, except for (i) those listed on Schedule 4.1(e), (ii) any
         filings or recordings required under the Loan Documents to perfect the
         security interest in favor of the Lender, each of which has been duly
         obtained or made and is in full force and effect, and (iii) filings and
         other actions required in connection with the exercise by the Lender of
         its remedies in respect of the Pledged Shares (as defined in the
         Collateral Documents).

                  (f) BINDING AND ENFORCEABLE. This Agreement is, and each other
         Loan Document to which any Loan Party will be a party is or when
         delivered will be, legal, valid and binding obligations of the Loan
         Parties enforceable against the Loan Parties in accordance with their
         respective terms, subject to laws generally affecting the enforcement
         of creditors' rights.

         the Borrower and its Subsidiaries as at December 31, 1994 and December
         31, 1995 and the related income and cash flow statements for the
         periods then ended, each other financial statement of the Borrower and
         its Subsidiaries delivered to the Lender on or prior to the Closing
         Date (excluding any forecasts or financial projections which may have
         been delivered to the Lender), and each financial statement delivered
         to the Lender pursuant to Section 5.2(c), as and when delivered to the
         Lender, fairly present the financial condition of the Borrower
         and its Subsidiaries as at the date thereof and the results of their
         operations for the period then ended, all in accordance with GAAP
         consistently applied but subject, in the case of unaudited financial
         statements, to normal year-end adjustments

         and the absence of footnotes.

                  (h) MATERIAL ADVERSE CHANGE. Since December 31, 1995, there
         has been no Material Adverse Change.

                  (i) COMPLIANCE. The execution, delivery and performance by
         each Loan Party of each Loan Document to which it is or will be a party
         complies with all applicable laws. Each Loan Party is in compliance in
         all material respects with all material applicable laws, rules,
         regulations and orders.

                  (j) LITIGATION. Set forth on Schedule 4.1(j) is a list, as of
         the Closing Date, of all pending or, to the Borrower's knowledge,
         overtly threatened actions or proceedings affecting any Loan Party
         before any court, governmental agency or arbitrator, other than any
         action or proceeding that would not subject the Loan Parties to
         liability in excess of $1,000,000 individually or in the aggregate.
         Except as identified on Schedule 4.1(j), there is no pending or, to the
         Borrower's knowledge, overtly threatened action or proceeding affecting
         any Loan Party before any court, governmental agency or arbitrator,
         which could reasonably be expected to result in a Material Adverse
         Change or which relates to or could reasonably be expected to affect
         the legality, validity or enforceability of any Loan Document.

                  (k) NO CONFLICT. The execution, delivery and performance by
         each Loan Party of each of the Loan Documents to which it is a party do
         not and will not (i) to its best knowledge, conflict with, result in a
         breach of, or constitute (with or without notice or the lapse of time
         or both) a default under, any instrument, lease, indenture, agreement
         or other contractual obligation issued by any Loan Party or enforceable
         against it or any of its property or assets if (A) such agreement is
         required to be filed with the Securities and Exchange Commission in
         accordance with the 1934 Act (or would be required to be so filed if
         the Borrower is subject to the reporting requirements of the 1934 Act),
         (B) such Agreement is not readily replaceable without any material
         adverse effect on such Loan Party or its business, or (C) any such
         conflict, breach or default would have a material adverse effect on the
         business of such Loan Party or (ii) require any approval of its
         stockholders or partners that has not been obtained.

                  (l) NO DEFAULT. No event has occurred and is continuing which
         constitutes an Event of Default or a Potential Default.

                  (m) PAYMENT OF TAXES. Each Loan Party has filed all federal
         income tax returns and all other tax returns required to be filed by it
         or has timely filed extensions relating thereto and has paid all taxes
         and assessments payable by it which have become due except (i) to the
         extent being contested in accordance with the provisions of Section
         5.2(h), and (ii) in the case of state and local tax returns and taxes,
         where the same would not reasonably be expected to result in aggregate
         liability to the Borrower and its Subsidiaries in excess of $500,000.

                  (n) MARGIN REGULATIONS. No proceeds of any Advance will be
         used for any purpose that requires any the Lender to deliver or obtain
         any certification under, or to comply with any margin requirement or
         other provision of, Regulations G, T, U or X of the Board of Governors
         of the Federal Reserve System.

                  (o) CONDUCT OF BUSINESS. The Borrower and its Subsidiaries are
         engaged in the lines of business described in Schedule 4.1(o) and
         activities substantially similar or reasonably incidental thereto.

                  (p) ENVIRONMENTAL MATTERS. Except as set forth in Schedule
         4.1(p), as it may from time to time be amended by the Borrower, no
         Material Environmental Claim is pending or, to the knowledge of the
         Borrower, overtly threatened against the Borrower or any of its
         Subsidiaries or any of their past or present property or assets. Except
         as set forth in Schedule 4.1(p), and except in respect of matters that,
         in the aggregate, are not and cannot reasonably be expected to result
         in a Material Environmental Claim or a Material Adverse Change, the
         operations of the Borrower and its Subsidiaries comply and, to the
         knowledge of the Borrower, have complied in all material respects with
         all applicable Environmental Laws.

                  (q) ERISA COMPLIANCE.

                           (i) Each Plan is in compliance in all material
                  respects with the applicable provisions of ERISA, the Code and
                  other applicable federal or state law.

                           (ii) Each Pension Plan which is intended to be
                  tax-qualified under Section 401(a) of the Code has been
                  determined by the Internal Revenue Service to qualify under
                  Section 401 of the Code, and the trusts created thereunder
                  have been determined to be exempt from tax under the
                  provisions of Section 501 of the Code, and to the best
                  knowledge of the Borrower nothing has occurred which would
                  cause the loss of such qualification or tax-exempt status.

                           (iii) Except as set forth in Schedule 4.1(q), (A)
                  none of the Pension Plans which is subject to Title IV of
                  ERISA has any material Unfunded Pension Liability as to which
                  the Borrower or any ERISA Affiliate is or may be liable; (B)
                  neither the Borrower nor any ERISA Affiliate has nor
                  reasonably expects to incur any material liability (and no
                  event has occurred which, with the giving of notice under
                  Section 4219 of ERISA, would result in such material
                  liability) under Section 4201 or 4243 of ERISA with respect to
                  any Multiemployer Plan; (C) no ERISA Event has occurred or, to
                  the best knowledge of the Borrower, is reasonably expected to
                  occur; and (D) neither the Borrower nor any ERISA Affiliate
                  has maintained any Welfare Plan which provides, or requires
                  the Borrower or any ERISA Affiliate to provide, medical or
                  other welfare benefits to



                                       38
<PAGE>   46

                  any participant after the termination of such participant's
                  employment with the Borrower or such ERISA Affiliate (except
                  to the extent required by the provisions of Part 6 of Title I,
                  Subtitle B of ERISA or Sections 162(k) and 4980B of the Code).

                           (iv) Each Welfare Plan which is a "group health
                  plan," as defined in Section 607(1) of ERISA, has been
                  operated in compliance with provisions of Part 6 of Title I of
                  ERISA and Sections 162(k) and 4980B of the Code at all times.

                           (v) Neither the Borrower nor any ERISA Affiliate has
                  engaged, directly or indirectly, in a prohibited transaction
                  (as defined in Section 4975 of the Code or Section 406 of
                  ERISA) for which no statutory or administrative exemption is
                  applicable in connection with any Plan the consequences of
                  which, in the aggregate, constitute or can reasonably be
                  expected to result in a Material Adverse Change.

                  (r) TITLE TO ASSETS. Each Loan Party has good and merchantable
         title to, or valid leasehold interest in, as of the date of each of its
         financial statements delivered hereunder, all of its material assets
         reflected therein and all assets and properties acquired since the date
         of such financial statements, free and clear of all Liens except Liens
         permitted under Section 5.3(a) (it being understood that the Galley
         Litigation and the Litigation Adjustment shall not be deemed a breach
         of this representation). Each Loan Party has complied with all material
         obligations under all leases of real property to which it is a party
         and under which it is in occupancy, and all such leases are in full
         force and effect and each Loan Party enjoys peaceful and undisturbed
         possession under all such leases.

                  (s) PERFECTION. On and after the Closing Date and, with
         respect to perfection upon the filing, recording or delivery of the
         financing statements, Intellectual Property Assignment, Transfer and
         Perfection Notices delivered pursuant to Section 3.1(a) or Section
         5.2(e), the provisions of each Collateral Document are effective to
         create, for the benefit of the Lender, legal, valid and perfected
         security interests in all right, title and interest in the Collateral
         described therein (to the extent that a security interest in such
         Collateral can be perfected by the filing, recording or delivery of
         such financing statements, Intellectual Property Security Agreement,
         Transfer and Perfection Notices) enforceable against each Loan Party
         that owns an interest in such Collateral, subject to laws generally
         affecting the enforcement of creditors' rights. The Loan Parties have
         delivered to the Lender the instruments constituting Collateral as to
         which (i) delivery to the Lender is required under Section 3.1(a) or
         Section 5.2(e), and (ii) possession by the Lender is required to
         perfect the security interest in favor of the Lender in such
         Collateral.

                  (t) UNDISCLOSED LIABILITIES. Except as set forth on Schedule
         4.1(t), neither the Borrower nor any of its Subsidiaries has any
         liabilities, contingent or otherwise, which



                                       39
<PAGE>   47

         are not reflected on the most recent financial statements delivered to
         the Lender pursuant to Section 5.2(c) and which could reasonably be
         expected to constitute a Material Adverse Change (it being understood
         that the Galley Litigation and the Litigation Adjustment shall not be
         deemed a breach of this representation).

         cumulative basis but without taking into account any loss incurred
         during any Fiscal Quarter), commencing with the Fiscal Quarter ending

         and as often as may be reasonably requested (but not more than twice

                                       42

         which it was incorporated or organized and all rights, privileges,
         qualifications, permits, licenses and franchises material to the normal
         conduct of its business, (ii) use its reasonable efforts, in the
         ordinary course and consistent with past practice, to preserve its
         business organization, reputation and goodwill, and (iii) preserve or
         renew all of its patent, copyrights, trademarks and licenses therefor
         and other intellectual property, in each case where the
         non-preservation of which constitutes or could reasonably be expected
         to result in a Material Adverse Change; PROVIDED, HOWEVER, that the
         Borrower may consummate any merger or consolidation permitted under
         Section 5.3(g); and PROVIDED, FURTHER, that neither the Borrower nor
         any of its Subsidiaries shall be required to preserve or maintain any
         right, asset, goodwill, business or franchise if the Borrower shall
         determine that the preservation thereof is not longer desirable in the
         conduct of the business of the Borrower or such Subsidiary, as the case
         may be, and that the loss thereof is not disadvantageous in any
         material respect to the Borrower, such Subsidiary or the Lender.

                  (e) NEW SUBSIDIARIES. Promptly, and in any event within ten
         (10) Business Days, after the date on which a new (direct or indirect)
         Subsidiary of the Borrower is formed or acquired, (i) notify the Lender
         of such event and (ii) amend Schedule 4.1(d); and promptly, and in any
         event within twenty (20) Business Days, after the formation,
         acquisition or change of each Material Subsidiary and each Foreign
         Subsidiary, (A) deliver to the Lender all stock certificates and other
         instruments added to the Collateral thereby (to the extent required by
         the Pledge and Security Agreements), accompanied by an undated stock
         power or transfer document executed in blank (provided that in the case
         of a Foreign Subsidiary, stock certificates or other instruments
         representing only sixty-five percent (65%) of the Borrower's equity
         interest therein shall be delivered to the Lender) and amend Schedules
         A, B and C of the appropriate Pledge and Security Agreement in light of
         such event; (B) cause each such Material Subsidiary (but not each such
         Foreign Subsidiary) to execute and deliver a joinder to the Guaranty, a
         joinder to the Subsidiary Pledge and Security Agreement, a joinder to
         the Intellectual Property Security Agreement, and all financing
         statements and other documents required thereunder or appropriate to
         perfect the security interest created thereby; and (C) deliver to the
         Lender in respect of the new Subsidiary an opinion of counsel
         confirming as to the new Subsidiary the matters required to be
         confirmed under Section 3.1(a)(iii) and 3.1(f), as applicable.

                  (f) MAINTENANCE OF PROPERTY. Maintain and preserve all its
         property which is necessary for use in its business in good working
         order and condition, except as permitted under Section 5.3(b), and
         except to the extent that the Borrower determines in good faith that it
         is not in the best interests of the Borrower and its Subsidiaries to do
         so.

                  (g) INSURANCE.

                           (i) Maintain insurance with financially sound and
                  reputable insurers with respect to its properties and business
                  against loss or damage of the kinds



                                       43
<PAGE>   51

                  consistent with industry practice of Persons engaged in the
                  same or similar business, of such types and in such amounts as
                  are carried under similar circumstances by such other Persons.

                           (ii) Maintain, at the Borrower's expense, a key man
                  life insurance policy for John Fruth, in an amount not less
                  than $5,000,000, which policy shall name the Lender as the
                  principal beneficiary, for the purpose of securing the
                  Obligations hereunder. During the continuance of an Event of
                  Default, all proceeds payable under such policy shall be paid
                  to the Lender to be applied on account of the Obligations
                  hereunder; during the continuance of a Potential Default (and
                  so long as no Event of Default is then continuing), all
                  proceeds payable under such policy shall be paid to the Lender
                  and held as cash collateral until such event becomes an Event
                  of Default (in which case the proceeds shall be applied to the
                  Obligations) or such event is cured or waived (in which case
                  the proceeds shall be paid to the Borrower); in all other
                  circumstances the proceeds of such policy shall be paid to the
                  Borrower. The receipt of such proceeds shall not be treated as
                  an extraordinary receipt under Section 2.5(d)(iii). Upon the
                  payment in cash in full of the Facility B Advance and any
                  accrued but unpaid interest thereunder, the Lender shall no
                  longer be named as the principal beneficiary of such insurance
                  policy.

                  (h) PAYMENT OF TAXES AND LIENABLE ITEMS. Pay and discharge, as
         they become due and payable, all claims for tax liabilities,
         assessments and governmental charges or levies against it or upon its
         properties or assets and all lawful claims which, if unpaid, would,
         with the passage of time or notice or both, by law become a Lien upon
         its property (other than a Lien permitted by Section 5.3(a) (excluding
         clause (x) thereof)), unless (i) such claim is contested in good faith,
         (ii) adequate reserves have been established for such claim to the
         extent required by GAAP or other adequate provision for the payment
         thereof has been made, (iii) enforcement of such claim is effectively
         stayed during any time as such claim may otherwise become a Lien, and
         (iv) if such claim is finally determined to be due, it is paid, with
         all interest or penalties thereon, promptly and in any event within the
         time period prescribed by applicable law, after resolution of such
         contest.

                  (i) USE OF PROCEEDS. Use the proceeds of the Advances solely
         for lawful and permitted corporate purposes of the Borrower and its
         Subsidiaries and not in contravention of this Agreement or any other
         agreement or obligation binding upon it and in strict compliance with
         all applicable laws, regulations and orders.

                  (j) PERMITTED CASH INVESTMENTS. To the extent it has cash,
         keep its cash (other than (i) cash in collection or disbursement, (ii)
         cash of Foreign Subsidiaries not in excess of $2,000,000 for each
         Foreign Subsidiary, and (iii) cash of O.S.I. Puerto Rico not in excess
         of $2,000,000) invested in such accounts and through such
         intermediaries that the Lender's security interest under the Borrower
         Pledge and Security Agreement and



                                       44

         Subsidiary Pledge and Security Agreement can lawfully be created and
         perfected by the provisions of such Pledge and Security Agreements and
         a Transfer and Perfection Notice to the depositary or intermediary.

                  (k) FURTHER ASSURANCES.

                           (i) Promptly (and in no event later than five (5)
                  Business Days after becoming aware thereof) notify the Lender
                  if any written information, exhibits and reports furnished to
                  the Lender contained any untrue statement of a material fact
                  or omitted to state any material fact or any fact necessary to
                  make the statements contained therein not misleading in light
                  of the circumstances in which made, and correct any defect or
                  error that may be discovered therein or in the execution,

                           (ii) Promptly upon request by the Lender, execute,
                  deliver, acknowledge, file, re-file, register and re-register
                  any and all such further acts, security agreements,
                  assignments, estoppel certificates, financing statements and
                  continuations thereof, termination statements, notices of
                  assignment, transfers, certificates, assurances and other
                  instruments as the Lender may reasonably require from time to
                  time in order (A) to carry out more effectively the purposes
                  of this Agreement or any other Loan Document, (B) to subject
                  to the Liens created by any of the Collateral Documents any of
                  the properties, rights or interests described in or intended
                  to be covered by any Collateral Document as being subject to
                  such Lien, (C) to establish and maintain the validity,
                  effectiveness, perfection and priority of any Collateral
                  Document or any Liens intended to be created thereby, (D) to
                  maintain the pledge to the Lender of (x) one hundred percent
                  (100%) of the outstanding equity interests of each domestic
                  Subsidiary or (y) sixty-five percent (65%) of the outstanding
                  equity interest of each Foreign Subsidiary, as required by

                  grant, assign, transfer, preserve, protect and confirm to the
                  Lender the rights granted or now or hereafter intended to be
                  granted to the Lender under any Loan Document or under any
                  other instrument executed in connection therewith.

                           (iii) Notwithstanding clause (ii) above, (A) the
                  Borrower shall not be required to deliver to the Lender notes
                  or other instruments evidencing loans and advances to
                  employees of the Borrower or any of its Subsidiaries, and (B)
                  the Borrower shall not be required to deliver to the Lender
                  any note or other instrument evidencing an intercompany loan
                  so long as the principal amount thereof is less than
                  $1,000,000.

                  SECTION V.3. NEGATIVE COVENANTS. So long as any Obligation
remains unpaid or the Lender is obligated to extend credit hereunder, without
the written consent of the Lender, the Borrower will not, and will not cause or

                  conducted by the Borrower and its Subsidiaries and activities
                  reasonably incidental thereto, so long as (A) the total
                  consideration (including cash, Debt incurred and value of
                  stock) paid for all such acquisitions does not exceed
                  $5,000,000 in the aggregate, (B) no Debt is assumed (other
                  than Debt secured solely by fixed assets being acquired) or
                  incurred in connection with the acquisition, (C) if the
                  acquisition is accomplished by merger or consolidation, the
                  Borrower is the surviving corporation, and (D) no Event of
                  Default or Potential Default is continuing or would result
                  from such acquisition.

                  (i) COMPLIANCE WITH ERISA. Directly or indirectly (or permit
         any ERISA Affiliate directly or indirectly to) (i) terminate any Plan
         subject to Title IV of ERISA so as to result in liability to the
         Borrower or any ERISA Affiliate in excess of $1,000,000; (ii) permit
         any ERISA Event to exist; (iii) make a complete or partial withdrawal
         (within the meaning of ERISA Section 4201) from any Multiemployer Plan
         so as to result in liability to the Borrower or any ERISA Affiliate in
         excess of $1,000,000; or (iv) permit the total Unfunded Pension
         Liabilities (using the actuarial assumptions utilized by the PBGC) for
         all Pension Plans (other than Pension Plans which have no Unfunded
         Pension Liabilities) to exceed $1,000,000.

                  (j) PAYMENT RESTRICTIONS AFFECTING SUBSIDIARIES. Cause, permit
         or suffer any Subsidiary to become or remain subject to any contractual
         obligation that in any manner limits or restricts its right to pay
         dividends or make distributions, whether in cash or in property, to its
         stockholders or to make loans or sell assets to the Borrower or any of
         its Subsidiaries or to enter into any other lawful transaction with the
         Borrower or any of its Subsidiaries, except (i) limitations and
         restrictions set forth in the Loan Documents and (ii) covenants
         contained in the existing documentation evidencing the Debt permitted
         under Section 5.3(d)(vi) or reflected in the commitment letter dated
         August 10, 1995 from the Government Development Bank for Puerto Rico to
         O.S.I. Puerto Rico and substantially similar covenants in any Debt
         replacing, extending, refinancing or renewing such Debt.

         the Lender; or

                  (d) REPRESENTATIONS AND WARRANTIES. Any representation or

                                       54
<PAGE>   62

         incorrect in any material respect when made; or

                  (e) FINANCIAL AND NEGATIVE COVENANTS. The Borrower fails to

         the Lender; or

                  (g) OTHER AGREEMENTS. The Borrower or any Loan Party fails to

         is given to the Borrower by the Lender; or

                  (h) DEFAULT AS TO OTHER DEBT. The Borrower or any of its

         Debt (except any Borrowings) outstanding in a principal amount of at
         least $1,000,000, and such failure continues for longer than the period
         of grace, if any, specified for such failure in the indenture or
         agreement governing such Debt, or (ii) commits, permits or suffers a

         event of default continues for longer than the period of grace, if any,
         specified for such failure in such indenture or agreement; or any such
         Debt of at least $1,000,000 is declared to be due and payable or is
         required to be prepaid prior to the stated maturity thereof; PROVIDED,
         HOWEVER, that no such failure, breach, default, event of default,
         declaration or requirement as to any Debt (x) which is the liability
         solely of a Foreign Subsidiary (except for the Debt permitted under

         (A) it is acknowledged in writing by the Borrower, or (B) it continues

         Debt is held entirely by the Borrower, or, in the case of the Borrower,
         such Debt is held entirely by one or more of its wholly-owned
         Subsidiaries; or

         instituted by or against any Loan Party or any Subsidiary of a Loan
         Party



                                       55

         seeking an order for relief under the United States Bankruptcy Code or
         seeking liquidation, winding up, reorganization, arrangement,
         adjustment, protection, relief, or composition of it or its debts or
         the appointment of a receiver, trustee, custodian or other similar
         official for it or for any substantial part of its property under any
         law relating to bankruptcy, insolvency, liquidation or reorganization
         or relief of debtors and either (A) any such relief in any such
         proceeding is sought or consented to by it or an order for any such
         relief is entered against it, or (B) any such proceeding instituted
         against it remains undismissed and unstayed for a period of sixty (60)
         days, or (C) any Loan Party or any Material Subsidiary takes any
         corporate action to authorize any of the actions set forth above in
         this Section 6.1(i); or

                  (j) JUDGMENTS. Any judgment or order for the payment of money
         is rendered against any of the Loan Parties or any of their
         Subsidiaries in an amount in excess of $1,000,000 individually or in
         the aggregate and either (i) enforcement proceedings are commenced by
         any creditor upon such judgment or order and not stayed, or (ii) there
         is any period of sixty (60) consecutive days during which such judgment
         has not been paid in full or a stay of enforcement of such judgment or
         order, by reason of a pending appeal or otherwise, is not in effect; or

                  (k) MATERIAL ADVERSE CHANGE. There is any Material Adverse
         Change since December 31, 1995; or

                  (l) LOAN DOCUMENTS. Any provision of any Loan Document after
         delivery thereof for any reason ceases to be valid and binding on each
         Loan Party thereto, or any Loan Party shall repudiate or purport to
         revoke or terminate any of its obligations under any Loan Document to
         which it is party, and such event continues for ten (10) Business Days
         after written notice thereof is given to the Borrower; or

                  (m) COLLATERAL DOCUMENTS. The Collateral Documents, after
         delivery thereof pursuant to Section 3.1(a), for any reason (other than
         pursuant to the terms thereof) cease to create a valid and perfected
         first priority security interest (subject to Liens permitted by Section
         5.3(a)) in any collateral purported to be covered thereby, and such
         event continues for ten (10) Business Days after written notice thereof
         is given to the Borrower; or

                  (n) ERISA. (i) The Borrower or any ERISA Affiliate fails to
         satisfy its contribution requirements under Section 412(c)(11) of the
         Code, whether or not it has sought a waiver under Section 412(d) of the
         Code; or (ii) in the case of an ERISA Event involving the withdrawal
         from a Pension Plan of a "substantial employer" (as defined in Section
         4001(a)(2) or Section 4062(e) of ERISA), the withdrawing employer's
         proportionate share of that Pension Plan's Unfunded Pension Liabilities
         is more than $1,000,000; or (iii) in the case of an ERISA Event
         involving the complete or partial withdrawal from a Multiemployer Plan,
         the withdrawing employer incurs a withdrawal liability in an aggregate
         amount exceeding $1,000,000; or (iv) a Plan that is intended to



                                       56
<PAGE>   64

         be qualified under Section 401(a) of the Code loses its qualification,
         and with respect to such loss of qualification, the Borrower or any
         ERISA Affiliate can reasonably be expected to be required to pay (for
         additional taxes, payments to or on behalf of Plan participants, or
         otherwise) an aggregate amount exceeding $1,000,000; or (vi) any
         combination of events listed in clauses (ii) through (iv) occurs that
         involves a net increase in aggregate Unfunded Pension Liabilities and
         unfunded liabilities in excess of $1,000,000;

then, and in any such event, the Lender (A) shall declare its obligation to make
Facility A Advances and issue Letters of Credit to be terminated, whereupon the
same shall forthwith terminate and the Facility A Amount shall be automatically
and permanently reduced to zero, and (B) shall by notice to the Borrower,
declare all Advances, together with all interest thereon and all other
Obligations, to be immediately due and payable, and thereupon the Advances and
such interest and all other Obligations, shall be immediately due and payable,
without presentment, demand, protest or further notice of any kind, all of which
are hereby expressly waived by the Borrower; PROVIDED, HOWEVER, that if an order
for relief under the United States Bankruptcy Code is entered at the request or
upon the consent of the Borrower or involuntarily against the Borrower (x) the
obligation of the Lender to make Facility A Advances and issue Letters of Credit
shall automatically be terminated and the Facility A Amount shall be
immediately, automatically and permanently reduced to zero, and (y) all Advances
and all such interest and other Obligations shall automatically become and be
immediately due and payable, without presentment, demand, protest or any notice
of any kind, all of which are hereby expressly waived by the Borrower.

                  SECTION VI.2. RIGHTS NOT EXCLUSIVE. The rights provided for in
this Agreement and the other Loan Documents are cumulative and are not exclusive
of any other rights, powers or privileges or remedies provided by law or in
equity, or under any other instrument, document or agreement.


                                   ARTICLE VII
                                  MISCELLANEOUS

                  SECTION VII.1. AMENDMENTS. No amendment or waiver of any
provision of this Agreement, nor consent to any departure by the Borrower
therefrom, shall be effective unless it is in writing and signed by the Lender
(and any such waiver or consent shall in any case be effective only in the
specific instance and for the specific purpose for which given), except that the
Borrower may amend Schedule 4.1(d) as provided in Section 5.2(e) by delivering a
copy of such amended Schedule to the Lender in accordance with Section 7.2.

                  SECTION VII.2. NOTICES. All notices and other communications
provided for hereunder shall be in writing (including telecopier, telegraphic,

Francisco, CA 94080, Attention: Chief Financial

Street, San Jose, CA 95113, Attention: Lori Edwards; or, as to each party, at
such other address as shall be designated by such party in a written notice to
the other parties. All such notices and communications shall be effective when
received.

                  SECTION VII.3. NO WAIVER; REMEDIES. No failure on the part of
the Lender to exercise, and no delay in exercising, any right under any Loan
Document shall operate as a waiver thereof; nor shall any single or partial
exercise of any such right preclude any other or further exercise thereof or the
exercise of any other right. The remedies herein provided are cumulative and not
exclusive of any remedies provided by law.

                  SECTION VII.4. COSTS AND EXPENSES. The Borrower agrees to pay
within twenty (20) days after the Borrower receives an invoice itemizing the
same, all reasonable out of pocket costs and expenses incurred by the Lender in
connection with the preparation, negotiation, execution, delivery, modification,
administration and amendment of the Loan Documents and the other documents to be
delivered under the Loan Documents, including the reasonable fees and
out-of-pocket expenses of counsel for the Lender with respect thereto and with
respect to advising the Lender as to its rights and responsibilities under the
Loan Documents in connection with actions or inactions of the Loan Parties and
including the Lender's Collateral audit fees, PROVIDED, HOWEVER, that attorneys
fees (excluding expenses, filing, recording fees and the like) incurred by the
Lender in connection with the preparation and negotiation of the Loan Documents
shall not exceed $50,000 provided that there are no more than four drafts of
this Agreement and four drafts of each other Loan Document. The Borrower further
agrees to pay on demand all reasonable costs and expenses, including reasonable
fees and expenses of attorneys (including allocable costs of in-house counsel),
accountants, advisors and other experts, incurred by the Lender in respect of
any Event of Default or while any Event of Default is continuing or in
connection with the protection, resolution or enforcement (whether through
negotiations, by legal proceedings, in bankruptcy or otherwise) of the
Obligations or the Collateral or any right, remedy, power, interest or claim of
the Lender under any Loan Document.

                  SECTION VII.5. RIGHT OF SET-OFF. Whenever any Event of Default
is continuing, the Lender may at any time or from time to time without any prior
notice to the Borrower or any other Person, set off and apply any and all
deposits (general or special, time or demand, provisional or final) at any time
held and other debt at any time owing by the Lender to or for the credit or the
account of the Borrower, whether or not then due, against any and all Advances
and other Obligations then owing to the Lender, whether or not then due. After
any such set-off and application is made, the Lender shall promptly notify the
Borrower thereof, but the failure to do so shall not affect the validity of the
set-off and application and shall not expose the Lender to any liability. The
Lender's right of set-off under this Section 7.5 is cumulative with and
additional to all other rights and remedies (including other rights of set-off).

                  SECTION VII.6. GENERAL INDEMNITY. The Borrower agrees to
indemnify and hold harmless the Lender and its Affiliates and each director,
officer, employee, attorney or agent of any of the foregoing persons (each such
Person, an "Indemnified Person") from any



                                       58
<PAGE>   66

losses, claims, costs, damages, expenses or liabilities (or actions, suits or
proceedings, including any inquiry or investigation, with respect thereto)
(collectively, "Claims") to which any Indemnified Person may become subject,
insofar as such Claims arise out of, in any way relate to, or result from, this
Agreement or any other Loan Document or any of the transactions contemplated
hereby and thereby and to reimburse upon demand each Indemnified Person for any
and all reasonable legal and other expenses incurred in connection with
investigating, preparing to defend or defending any such Claim; PROVIDED,
HOWEVER, that the Borrower shall not have any indemnity obligation to any
Indemnified Person for any Claim (i) based on or arising from the gross
negligence or wilful misconduct of such Indemnified Person or a breach of any
Loan Document or applicable law by an Indemnified Person or (ii) made or
prosecuted by the Borrower. The Borrower shall be given prompt notice of the
commencement of any action or proceeding on any Claim and of any overt written
threat of litigation on any Claim, but the failure to receive such notice shall
not relieve the Borrower from any of its obligations under this Section 7.6 or
under Section 7.4. The Borrower shall have the right, with the consent of the
Indemnified Person (which shall not unreasonably be withheld), to select a firm
of attorneys as legal counsel to defend any Claim, and the Borrower shall pay
the fees, expenses and disbursements of such counsel and any special or local
counsel; and if the Indemnified Person would or could result in a conflict of
interest, or that a defense, crossclaim or counterclaim is available to such
Indemnified Person that is not available to any other Person represented by such
legal counsel in the same proceeding, then to the extent reasonably necessary to
avoid such a conflict of interest or to permit unqualified assertion of such a
defense, crossclaim or counterclaim, such Indemnified Person shall be entitled
to separate representation, at the Borrower's expense, by legal counsel selected
by such Indemnified Person and reasonably acceptable to the Borrower, with all
such legal counsel using reasonable efforts to avoid unnecessary duplication of
effort by counsel. Each Indemnified Person shall have the right to be
represented by counsel of its own choosing (A) at the Borrower's expense
whenever any Event of Default or Potential Default is continuing and (B) at such
Indemnified Person's expense at any time; and the Borrower and the attorneys
selected by the Borrower shall cooperate in all reasonable respects with such
counsel. The Borrower shall be entitled to settle any Claim, at the Borrower's
sole cost and expense, without consent of the Indemnified Person if (x) no Event
of Default or Potential Default is continuing, (y) the settlement does not and
will not, under any circumstances, impose any present or future payment or
performance obligation upon the Indemnified Person, and (z) the settlement
includes the giving by the claimant to the Indemnified Person of a release from
all liability in respect of such Claim; and otherwise only upon the prior
written consent of the Indemnified Person.

                  SECTION VII.7. ASSIGNMENTS AND PARTICIPATIONS. The Lender may
at any time, sell, assign, grant participation in, or otherwise transfer all or
any part of its rights and obligations under this Agreement (i) without the
Borrower's consent if such transfer is to a Federal Reserve Bank or to an
Affiliate of the Lender or if an Event of Default is continuing and (ii) with
the Borrower's consent (which consent shall not be unreasonably withheld) to any
other Person. In the event of any such sale by the Lender of a participation,
the holder of such participation, other than an Affiliate of the Lender, shall
not have any rights under this Agreement except that such holder may under the
terms of such participation, be granted the right to participate with the Lender
in connection with any action that (i) increases the Facility Amount, (ii)
postpones the scheduled final maturity date of Facility A or Facility B, (iii)
postpones any scheduled Facility B payment date, (iv) postpones any nonscheduled
mandatory reduction of Facility B, (v) decreases the rate of interest applicable
to any Advances, (vi) releases all or substantially all of the Collateral, or
any right to obtain additional Collateral, or (vii) releases any Guarantor or
any right to have an additional Material Subsidiary become a Guarantor. In all
other respects, the Lender's obligations under this Agreement shall remain
unchanged, the Lender shall remain solely responsible for the performance
thereof, and the Borrower shall continue to deal solely and directly with the
Lender in connection with the Lender's rights and obligations under this
Agreement. The Borrower hereby authorizes the Lender and each such participant
or assignee, in case of default by the Borrower hereunder to proceed directly by
right of setoff, bankers' lien, or otherwise, against any assets of the Borrower
which may at the time of such default be in the hands of the Lender or any such
participant or assignee.

                  SECTION VII.8. BINDING EFFECT. This Agreement shall become
effective when it has been executed by the parties hereto and the conditions set
forth in Section 3.1 have been satisfied and thereafter shall be binding upon
and inure to the benefit of the Borrower and the Lender and their respective
successors and assigns, except that the Borrower shall not have the right to
assign its rights hereunder or any interest herein without the prior written
consent of the Lender.

                  SECTION VII.9. GOVERNING LAW. This Agreement and the other
Loan Documents shall be governed by, and construed in accordance with, the laws
of the State of California. Any legal action or proceeding with respect to any
Loan Document may be brought in the courts of the State of California or of the
United States for the Northern District or the Central District of California,
and by execution and delivery of this Agreement, each of the Borrower and the
Lender consents, for itself and in respect of its property, to the jurisdiction
of those courts. Each of the Borrower and the Lender irrevocably waives any
objection, including any objection to the laying of venue or based on the
grounds of forum non conveniens, which it may now or hereafter have to the
bringing of any action or proceeding in such jurisdiction in respect of any Loan
Document. The Borrower and the Lender each waive personal service of any
summons, complaint or other process, which may be made by any other means
permitted by California law.

                  SECTION VII.10. WAIVER OF JURY TRIAL. The Borrower and the
Lender



                                       60
<PAGE>   68

WAIVE THEIR RESPECTIVE RIGHTS TO A TRIAL BY JURY of any claim or cause of action
based upon or arising out of or related to this Agreement or any other Loan
Document or the transactions contemplated hereby or thereby in any action,
proceeding or other litigation of any type brought by any of the parties against
any other party or parties, whether based on contract, tort, statutory liability
or otherwise. The Borrower and the Lender agree that any such claim or cause of
action shall be tried by the court WITHOUT A JURY. This waiver shall apply to

extent permitted by law, for any punitive damages in respect of any claim or
cause of action (whether based on contract, tort, statutory liability, or any
other ground) based on, arising out of or related to any Loan Document or the
transactions contemplated hereby or any act, omission or event occurring in
connection therewith, and the Borrower (for itself and on behalf of each of its
Subsidiaries), and the Lender hereby waives, releases and agrees never to sue
upon any claim for any such damages, whether such claim now exists or hereafter
arises and whether or not it is now known or suspected to exist in its favor.

to the Lender or its directors, officers, employees or advisors prior to its
disclosure by the Borrower, (iv) information that has become publicly available
other than by the Lender's improper disclosure, (v) information that is obtained
from any source other than the Borrower or its Affiliates, unless the Lender has
actual knowledge that such source disclosed such information to it in breach of
an obligation of confidentiality, and (vi) as may be required or appropriate in
any proceeding to collect the Obligations or protect or enforce any right or
remedy of the Lender under the Loan Documents or in defense of any claim
asserted against the Lender or in any other litigation or for compliance with
any applicable law or any subpoena, discovery request or other legal process, so
long as the Lender (if not prohibited from doing so) gives the Borrower at least
three (3) Business Days' prior notice thereof.

                  SECTION VII.13. ENTIRE AGREEMENT. This Agreement, together
with the other Loan Documents, embodies the entire Agreement and understanding

and expects to derive substantial direct and indirect benefit from the

         D. The Borrower has agreed, in the Credit Agreement, to cause all
future Material Subsidiaries of the Borrower to become party to this Guaranty,

         NOW, THEREFORE, in consideration of the foregoing and in order to
induce the Lender to extend credit to the Borrower under the Credit Agreement,
each Guarantor hereby agrees as follows:

                                    ARTICLE I

<PAGE>   75
                  "Guaranteed Obligations" is defined in Section 2.1(a).

                         GUARANTY AND RELATED PROVISIONS

                  SECTION II.1 Guaranty. Each Guarantor hereby unconditionally:

                  (a) guarantees the punctual payment when due, whether at
         stated maturity, by acceleration or otherwise, of (i) all Obligations
         now outstanding or hereafter arising under or in connection with the
         Credit Agreement or any other Loan Document, whether for principal,
         interest, fees, taxes, additional compensation, expense reimbursements,
         indemnification or otherwise, and (ii) all liabilities of each
         Guarantor now outstanding or hereafter arising under the Guaranty and
         any Subsidiary Joinder, and (iii) each other debt, liability or
         obligation of the Borrower or any Subsidiary of the Borrower now
         outstanding or hereafter arising under any of the Loan Documents (such
         Obligations, liabilities and other debts, liabilities and obligations,
         collectively, are the "Guaranteed Obligations"), and

                  (b) agrees to pay on demand (i) all Disallowed
         Post-Commencement Interest and Expenses, to the Person entitled to
         payment thereof if the claim therefor had been allowed in any
         Bankruptcy, Insolvency or Liquidation Proceeding, and (ii) all costs
         and expenses (including, without limitation, reasonable attorneys' fees
         and legal expenses) incurred by the Lender in enforcing this Guaranty.

                  SECTION II.2 Acceleration of Payment. If (i) the Advances
become immediately due and payable pursuant to Section 6.1 of the Credit
Agreement, (ii) any Bankruptcy, Insolvency or Liquidation Proceeding is
commenced voluntarily by any Guarantor, or (iii) any Bankruptcy, Insolvency or
Liquidation Proceeding is commenced involuntarily against any Guarantor and
either (x) remains pending for more than 30 days or (y) an order for relief is
granted or consented to by the Borrower or by the debtor therein, then all
liability of each Guarantor under this Guaranty in respect of any Guaranteed
Obligation that is not then due and payable shall thereupon become and be
immediately due and payable, without notice or demand.

                  SECTION II.3 Guaranty Absolute and Unconditional. Each
Guarantor guarantees that the Guaranteed Obligations will be paid in accordance
with the terms of the Credit Agreement and the other Loan Documents, regardless
of any law, regulation or order now or hereafter in effect in any jurisdiction
affecting any of such terms or the rights and claims of the Lender against the
Borrower or any Subsidiary of the Borrower with respect thereto and even if any
such rights or claims are modified, reduced or discharged in a Bankruptcy,
Insolvency or Liquidation Proceeding or otherwise. The obligations of each
Guarantor under this Guaranty are



                                        2

<PAGE>   76

independent of the Guaranteed Obligations, and a separate action or actions may
be brought and prosecuted against each Guarantor to enforce this Guaranty,
whether or not any action is brought against the Borrower or any other Guarantor
and whether or not the Borrower or any other Guarantor is joined in any such
action or actions. The liability of each Guarantor under this Guaranty shall be
absolute and unconditional irrespective of: (i) any lack of validity or
enforceability of the Credit Agreement or any other Loan Document or any other
agreement or instrument relating thereto; (ii) any change in the time, manner or
place of payment of, or in any other term of, any of the Guaranteed Obligations,
or any other amendment or waiver of or any consent to departure from the Credit
Agreement or any other Loan Document, including, without limitation, any
increase in the Guaranteed Obligations resulting from the extension of
additional credit to the Borrower or any of its Subsidiaries or otherwise; (iii)
any taking, exchange, release or non-perfection of any Lien securing, or any
taking, release or amendment or waiver of or consent to departure from any other
guaranty of, any of the Guaranteed Obligations; (iv) any manner or order of sale
or other enforcement of any Lien securing any or all of the Guaranteed
Obligations or any manner or order of application of the proceeds of any such
Lien to the payment of the Guaranteed Obligations or any failure to enforce any
Lien or to apply any proceeds thereof; (v) any change, restructuring or
termination of the corporate structure or existence of the Borrower or any of
its Subsidiaries; or (vi) any other circumstance which might otherwise
constitute a defense (except the defense of payment) available to, or a
discharge of, a surety or guarantor.

                  SECTION II.4 Guaranty Irrevocable and Continuing. This
Guaranty is an irrevocable and continuing offer and agreement guaranteeing
payment of any and all Guaranteed Obligations and shall extend to all Guaranteed
Obligations now outstanding or created or incurred at any future time, whether
or not created or incurred pursuant to any agreement presently in effect or
hereafter made, until all obligations of the Lender to extend credit to the
Borrower have expired or been terminated and all Guaranteed Obligations have
been fully, finally and indefeasibly paid. To the extent any contingent
Obligation survives the expiration or termination of the Credit Agreement and
the repayment of the Advances, each Guarantor's liability under this Guaranty
shall likewise survive. This Guaranty may be released only in writing except,
with respect to a given Guarantor, as provided for in Section 2.10.

                  SECTION II.5 Reinstatement. If at any time any payment on any
Guaranteed Obligation is set aside, avoided or rescinded or must otherwise be
restored or returned, this Guaranty and the liability of each Guarantor under
this Guaranty shall remain in full force and effect and, if previously released
or terminated, shall be automatically and fully reinstated, without any
necessity for any act, consent or agreement of any Guarantor, as fully as if
such payment had never been made and as fully as if any such release or
termination had never become effective.

                  SECTION II.6 Waiver. Guarantor hereby waives and relinquishes
all rights, remedies and defenses accorded by applicable law to sureties or
guarantors and agrees not to assert or take advantage of any such rights,
remedies or defenses, including without limitation:

                  (a) any right to require the Lender to proceed against
         Borrower or any other Person or to proceed against or exhaust any
         security held by the Lender at any time or to pursue any other remedy
         in the power of the Lender before proceeding against Guarantor;

                  (b) the defense of the statute of limitations in any action
         hereunder or in any action for the



                                        3

<PAGE>   77

         collection or performance of any Guaranteed Obligations;

                  (c) any defense that may arise by reason of the incapacity,
         lack of authority, death or disability of any other Person or the
         failure of the Lender to file or enforce a claim against the estate (in
         administration, bankruptcy or any other proceeding) of any other
         Person;

                  (d) demand, presentment, protest and notice of any kind,
         including without limitation notice of the existence, creation or
         incurring of any new or additional indebtedness or obligation or of any
         action or non-action on the part of Borrower, Lender, any endorser or
         creditor of Borrower or Guarantor or on the part of any other Person
         under this or any other instrument in connection with any obligation or
         evidence of indebtedness held by Lender as Collateral or in connection
         with any Guaranteed Obligations;

                  (e) any defense based upon an election of remedies by the
         Lender (including without limitation an election to proceed by
         non-judicial rather than judicial foreclosure) irrespective of whether
         such election destroys or otherwise impairs any subrogation rights of
         Guarantor, the right of Guarantor to proceed against Borrower for
         reimbursement, or both (it being understood that as a consequence of
         the waiver set forth in this Section 2.6(e), Guarantor is waiving,
         among other things, any defense that Guarantor might be able to invoke
         under California law based upon the argument (as enunciated in, among
         other cases, Union Bank v. Gradsky, 265 Cal. App. 2d 40 (1968), and
         Cathay Bank v. Lee, 93 Los Angeles Daily Journal D.A.R. 4871 (1993)),
         that an election by a lender to foreclose non-judicially under a deed
         of trust effects a release of the Guarantor from any obligation to pay,
         under its guaranty, any portion of the guaranteed obligation remaining
         unpaid after the non-judicial foreclosure since the non-judicial
         foreclosure could destroy or impair Guarantor's subrogation or other
         rights to obtain any reimbursement from the Borrower for such
         payments);

                  (f) any defense based upon any statute or rule of law which
         provides that the obligation of a surety must be neither larger in
         amount nor in other respects more burdensome than that of the
         principal;

                  (g) any duty on the part of the Lender to disclose to
         Guarantor any facts the Lender may now or hereafter know about
         Borrower, regardless of whether the Lender has reason to believe that
         any such facts materially increase the risk beyond that which Guarantor
         intends to assume, or has reason to believe that such facts are unknown
         to Guarantor, or has a reasonable opportunity to communicate such facts
         to Guarantor, since Guarantor acknowledges that Guarantor is fully
         responsible for being and keeping informed of the financial condition
         of Borrower and of all circumstances bearing on the risk of non-payment
         of any Guaranteed Obligations;

                  (h) any defense arising because of the election by the Lender,
         in any proceeding instituted under the Bankruptcy Code, of the
         application of Section 1111(b)(2) of the Bankruptcy Code; and

                  (i) any defense based upon any borrowing or grant of a
         security interest under Section 364 of the Federal Bankruptcy Code.

                  Without limiting the generality of the foregoing, Guarantor
hereby expressly waives any and all benefits which might otherwise be available
to Guarantor under California Civil Code Sections 2809, 2810, 2819,

2839, 2845 through 2850, 2899 and 3433, California Code of Civil Procedure
Sections 580(a), 580(b), 580(d) and 726, and California Commercial Code Section
3606(1).

                  SECTION II.7 Subrogation. Each Guarantor hereby represents,
warrants and agrees, in respect of any and all present and future rights of
subrogation, recourse, reimbursement, indemnity, exoneration, contribution and
other claims that such Guarantor at any time may have against the Borrower, any
other Guarantor or any other Person liable for the payment of any of the
Guaranteed Obligations (including, without limitation, the owner of any interest
in collateral subject to a Lien securing any of the Guaranteed Obligations) as a
result of or in connection with this Guaranty or any payment hereunder, that:

                  (a) No Agreement. Such Guarantor has not entered into, and
         agrees that it will not enter into, any agreement providing, directly
         or indirectly, for any such right or claim against the Borrower or,
         except as set forth in Section 2.10, against any other Subsidiary of
         the Borrower, and each such agreement now existing or hereafter entered
         into (except as provided for in Section 2.10) is and shall be void;

                  (b) Release. Such Guarantor waives and releases any such right
         or claim against the Borrower, any other Guarantor or any other such
         Person until the Guaranteed Obligations have been paid in full;

                  (c) Capital Contribution. Neither the execution and delivery
         of this Guaranty by such Guarantor nor any payment by such Guarantor
         under this Guaranty shall give rise to any claim (as that term is
         defined in the Bankruptcy Code) in favor of such Guarantor against the
         Borrower until the Guaranteed Obligations have been paid in full; and

                  (d) Subordination of Contribution Rights. Such Guarantor
         reserves, as against each other Guarantor, its right of contribution
         under Section 2.10 but agrees that all such contribution rights shall
         be included among the Subordinated Liabilities.

                  SECTION II.8 Subordination Provisions.

                  (a) Subordination. Any and all present and future debts,
         liabilities and obligations of every type and description (whether for
         money borrowed, on intercompany accounts, for provision of goods or
         services, under tax sharing or contribution agreements or on account of
         any other transaction, agreement, occurrence or event and whether
         absolute or contingent, direct or indirect, matured or unmatured,
         liquidated or unliquidated, created directly or acquired from another,
         or sole, joint, several or joint and several) of the Borrower or any
         Subsidiary of the Borrower now outstanding or hereafter incurred or
         owed to any Guarantor (the "Subordinated Liabilities") shall be, and
         hereby are, subordinated to full and final payment of the Guaranteed
         Obligations.

                  (b) Prohibited Payments. If any Event of Default or Potential
         Default occurs, then for so long as such Event of Default or Potential
         Default may be continuing, no Guarantor will demand, sue for, accept or
         receive, or cause or permit any other Person to make, any payment on or
         transfer of property on account of any Subordinated Liabilities.



                                        5

<PAGE>   79

                  (c) No Liens or Transfers. Each Guarantor agrees that (i) it
         will not demand, accept or hold any Lien upon any real or personal
         property of the Borrower or any of its Subsidiaries as security for any
         of the Subordinated Liabilities and (ii) any such Lien shall be void.

                  (d) Insolvency Proceedings. In any Bankruptcy, Insolvency or
         Liquidation Proceeding, the Lender shall be entitled to receive payment
         in full of all amounts due or to become due on or in respect of the
         Guaranteed Obligations, or provision shall be made for such payment in
         money or money's worth, before any Guarantor is entitled to receive any
         payment or distribution of any kind or character, whether in cash,
         property or securities, on account of any of the Subordinated
         Liabilities, and to that end the Lender shall be entitled to receive,
         for application to the payment thereof, all payments and distributions
         of any kind or character, whether in cash, property or securities
         (including any such payment or distribution which may be payable or
         deliverable by reason of the payment of any other debt or liability of
         the Borrower or any Subsidiary of the Borrower being subordinated to
         the payment of the Subordinated Liabilities), which may be payable or
         deliverable in respect of the Subordinated Liabilities in any such
         Bankruptcy, Insolvency or Liquidation Proceeding.

                  (e) Disallowed Post-Commencement Interest and Expenses. If in
         any Bankruptcy, Insolvency or Liquidation Proceeding (i) any payment or
         distribution of any kind or character, whether in cash, property or
         securities (including any such payment or distribution which may be
         payable or deliverable by reason of the payment of any other debt or
         liability of the Borrower or any Subsidiary of the Borrower being
         subordinated to the payment of the Subordinated Liabilities) is payable
         or deliverable in respect of the Subordinated Liabilities, and (ii) the
         Lender is not otherwise entitled to receive such payment or
         distribution pursuant to Section 2.8(d), and (iii) any amount remains
         unpaid to the Lender on account of any Disallowed Post- Commencement
         Interest and Expenses, then the Lender shall be entitled to receive
         payment of all such unpaid Disallowed Post-Commencement Interest and
         Expenses from and out of any and all such payments and distributions in
         respect of the Subordinated Liabilities.

                  (f) Held in Trust. If any payment, transfer or distribution is
         made to any Guarantor upon any Subordinated Liabilities that is not
         permitted to be made under this Section 2.8 or that the Lender is
         entitled to receive under this Section 2.8, such Guarantor shall
         receive and hold the same in trust, as trustee for the benefit of the
         Lender, and shall forthwith transfer and deliver the same to the
         Lender, in precisely the form received (except for any required
         endorsement), for application to the payment of Guaranteed Obligations
         or any unpaid Disallowed Post-Commencement Interest and Expenses.

                  (g) Claims in Bankruptcy. Each Guarantor will file all claims
         against the Borrower or any Subsidiary of the Borrower in any
         Bankruptcy, Insolvency or Liquidation Proceeding in which the filing of
         claims is required or permitted by law upon any of the Subordinated
         Liabilities and will assign to the Lender, all rights of such Guarantor
         thereunder. If any Guarantor does not file any such claim at least 30
         days prior to any applicable claims bar date, the Lender is hereby
         authorized (but shall not be obligated), as attorney-in-fact for such
         Guarantor with full power of substitution, either to file such claim or
         proof thereof in the name of such Guarantor or, at the option of the
         Lender, to assign the claim and cause the claim or proof thereof to be
         filed by an agent or nominee. The Lender and its agents and nominees
         shall have the sole right, but no obligation, to accept or reject any
         plan proposed in such Bankruptcy, Insolvency or Liquidation Proceeding
         and to cast any votes and to take any other action with respect to




                                        6

<PAGE>   80

         all claims upon any of the Subordinated Liabilities.

                  (h) Subordination Effective and not Impaired. This Section 2.8
         shall remain effective for so long as this Guaranty is continuing and
         thereafter for so long as any Guaranteed Obligation is outstanding.
         Each Guarantor's obligations under this Section 2.8: (i) shall be
         absolute and unconditional as set forth in Section 2.3, irrevocable and
         continuing as set forth in Section 2.4, subject to reinstatement as set
         forth in Section 2.5 and not be affected or impaired by any of the
         matters waived in Section 2.6; (ii) shall be subject to the provisions
         of Article III; and (iii) shall otherwise be as equally enduring and
         free from defenses as such Guarantor's liability under this Guaranty.

                  SECTION II.9 Fraudulent Transfer Limitation. If, in any action
to enforce this Guaranty or any proceeding to allow or adjudicate a claim under
this Guaranty, a court of competent jurisdiction determines that enforcement of
this Guaranty against any Guarantor for the full amount of the Guaranteed
Obligations is not lawful under, or would be subject to avoidance under, Section
548 of the Bankruptcy Code or any applicable provision of comparable state law,
the liability of such Guarantor under this Guaranty shall be limited to the
maximum amount lawful and not subject to avoidance under such law.

                  SECTION II.10 Contribution among Guarantors. The Guarantors
desire to allocate among themselves, in a fair and equitable manner, their
rights of contribution from each other when any payment is made by one of the
Guarantors under this Guaranty. Accordingly, if any payment is made by a
Guarantor under this Guaranty (a "Funding Guarantor") that exceeds its Fair
Share, the Funding Guarantor shall be entitled to a contribution from each other
Guarantor in the amount of such other Guarantor's Fair Share Shortfall, so that
all such contributions shall cause each Guarantor's Aggregate Payments to equal
its Fair Share. For these purposes:

                  (a) "Fair Share" means, with respect to a Guarantor as of any
         date of determination, an amount equal to (i) the ratio of (x) the
         Adjusted Maximum Amount of such Guarantor to (y) the aggregate Adjusted
         Maximum Amounts of all Guarantors, multiplied by (ii) the aggregate
         amount paid on or before such date by all Funding Guarantors under this
         Guaranty.

                  (b) "Fair Share Shortfall" means, with respect to a Guarantor
         as of any date of determination, the excess, if any, of the Fair Share
         of such Guarantor over the Aggregate Payments of such Guarantor.

                  (c) "Adjusted Maximum Amount" means, with respect to a
         Guarantor as of any date of determination, the maximum aggregate amount
         of the liability of such Guarantor under this Guaranty, limited to the
         extent required under Section 2.9 (except that, for purposes solely of
         this calculation, any assets or liabilities arising by virtue of any
         rights to or obligations of contribution under this Section 2.10 shall
         not be counted as assets or liabilities of such Guarantor).

                  (d) "Aggregate Payments" means, with respect to a Guarantor as
         of any date of determination, the aggregate net amount of all payments
         made on or before such date by such Guarantor under this Guaranty
         (including, without limitation, under this Section 2.10).

The amounts payable as contributions hereunder shall be determined by the
Funding Guarantor as of the date on which the related payment or distribution is
made by the Funding Guarantor, and such determination shall be




                                        7

<PAGE>   81

binding on the other Guarantors absent manifest error. The allocation and right
of contribution among the Guarantors set forth in this Section 2.10 shall not be
construed to limit in any way the liability of any Guarantor under this Guaranty
to the Lender.

                  SECTION II.11 Joint and Several Obligation. This Guaranty and
all liabilities of each Guarantor hereunder shall be the joint and several
obligation of each Guarantor and may be freely enforced against each Guarantor,
for the full amount of the Guaranteed Obligations (subject to Section 2.9),
without regard to whether enforcement is sought or available against any other
Guarantor.

                                   ARTICLE III
                            MISCELLANEOUS PROVISIONS

                  SECTION III.1 Condition of the Borrower. Each Guarantor is
fully aware of the financial condition of the Borrower and its Subsidiaries and
is executing and delivering this Guaranty based solely upon such Guarantor's own
independent investigation of all matters pertinent hereto and is not relying in
any manner upon any representation or statement by the Lender. Each Guarantor
represents and warrants that it is in a position to obtain, and each Guarantor
hereby assumes full responsibility for obtaining, any additional information
concerning the financial condition of the Borrower and each of its Subsidiaries
and any other matter pertinent hereto as such Guarantor may desire, and such
Guarantor is not relying upon or expecting the Lender to furnish to such
Guarantor any information now or hereafter in the possession of the Lender
concerning the same or any other matter. By executing this Guaranty, each
Guarantor knowingly accepts the full range of risks encompassed within a
contract of this type, which risks each Guarantor acknowledges. No Guarantor
shall have the right to require the Lender to obtain or disclose any information
with respect to the Guaranteed Obligations, the financial condition or prospects
of the Borrower or any Subsidiary of the Borrower, the ability of the Borrower
or any Subsidiary of the Borrower to pay or perform the Guaranteed Obligations,
the existence, perfection, priority or enforceability of any collateral security
for any or all of the Guaranteed Obligations, the existence or enforceability of
any other guaranties of all or any part of the Guaranteed Obligations, any
action or non-action on the part of the Lender, the Borrower, any Subsidiary of
the Borrower or any other Person, or any other event, occurrence, condition or
circumstance whatsoever.

                  SECTION III.2 Amendments.

                  (a) Amendment to Guaranty. No amendment or waiver of any
         provision of this Guaranty, no consent to any departure by any
         Guarantor herefrom, shall in any event be effective unless the same
         shall be in writing and signed by the Lender, and then such waiver or
         consent shall be effective only in the specific instance and for the
         specific purpose for which given, except that no amendment, waiver or
         consent shall, unless in writing and signed by the Lender, (i) reduce
         or discharge the liability of any Guarantor hereunder, or (ii) postpone
         any date fixed for payment hereunder.

                  (b) Amendment or Modification of Other Loan Documents. The
         other Loan Documents may be amended, modified or supplemented in
         accordance with their terms without notice to or consent or agreement
         by any Guarantor, including, without limitation, so as to (i) alter,
         compromise, modify, accelerate, extend, renew, refinance or change the
         time or manner for making of Advances, provision of



                                        8

<PAGE>   82

         other financial accommodations, or the payment or performance of all or
         any portion of the Guaranteed Obligations, (ii) increase or reduce the
         rate of interest or amount of principal payable on the Guaranteed
         Obligations, (iii) release or discharge the Borrower, any other Loan
         Party or any other Person as to all or any portion of the Guaranteed
         Obligations, or (iv) release, substitute or add any one or more
         guarantors or endorsers, accept additional or substituted security for
         payment or performance of the Guaranteed Obligations, or release or
         subordinate any security therefor.

                  SECTION III.3 Notices. All notices and other communications
provided for hereunder shall be in writing (including telecopier, telegraphic,
telex or cable communication) and mailed, telecopied, telegraphed, telexed,
cabled or delivered, if to any Guarantor, c/o O.S.I. Corporation, 475 Eccles
Avenue, South San Francisco, California 94080, Attention: Treasurer, with a copy
to the General Counsel at the same address, and if to the Lender, at its address
specified in the Credit Agreement, or, as to any party, at such other address as
shall be designated by such party in a written notice to each other party. All
such notices and other communications shall, when mailed, telecopied,
telegraphed, telexed or cabled, be effective when deposited in the mails,
telecopied, delivered to the telegraph company, confirmed by telex answerback or
delivered to the cable company, respectively.

                  SECTION III.4 Right of Set off. If any Advances become
immediately due and payable pursuant to Section 6.1 of the Credit Agreement, the
Lender shall have the right at any time, and from time to time thereafter, to
the fullest extent permitted by law, to set off and apply any and all deposits
(general or special, time or demand, provisional or final) at any time held and
other liability at any time owing by Lender to or for the credit or the account
of any Guarantor against any and all liability of such Guarantor under this
Guaranty, whether or not Lender shall have made any demand under this Guaranty
and even though such deposit or liability may then be unmatured. Lender agrees
to promptly notify the affected Guarantor after any such set-off and application
made by Lender, but the failure to give such notice shall not affect the
validity of such set-off and application. The rights of the Lender under this
Section 3.4 are in addition to other rights and remedies (including, without
limitation, other rights of set-off) which Lender may have.

                  SECTION III.5 Successors and Assigns. This Guaranty is binding
upon and enforceable against each Guarantor, its successors and assigns, and
shall inure to the benefit of, and be enforceable by, the Lender and its
representatives, successors and assigns.

                  SECTION III.6 No Inquiry. The Lender may rely, without further
inquiry, on the power and authority of each Guarantor, the Borrower and each of
its Subsidiaries and on the authority of all officers, directors and agents
acting or purporting to act on their behalf.

                  SECTION III.7 Involuntary Proceedings. So long as the Lender
is obligated to extend credit under the Credit Agreement or any Guaranteed
Obligations are outstanding, no Guarantor will, without the prior written
consent of the Lender, commence or join with any other Person in commencing any
Bankruptcy, Insolvency or Liquidation Proceeding against the Borrower or any of
its Subsidiaries.

                  SECTION III.8 Payments Free and Clear of Taxes.

                  (a) Payment. Each Guarantor agrees to pay any and all present
         or future taxes, levies, imposts, deductions, charges or withholdings,
         and all liabilities with respect thereto which arise from any



                                        9

<PAGE>   83

         payment made hereunder or from the execution, delivery or registration
         of, or otherwise with respect to, this Guaranty, excluding, with
         respect to the Lender, taxes imposed on its net income (collectively,
         the "Guaranty Taxes").

                  (b) Indemnity. Each Guarantor hereby indemnifies the Lender
         for the full amount of Guaranty Taxes (including, without limitation,
         any Guaranty Taxes imposed by any jurisdiction on amounts payable under
         this Section 3.8) paid by the Lender and any liability (including
         penalties, interest and expenses) arising therefrom or with respect
         thereto (plus interest on any amounts not paid within thirty days from
         the date written demand is made therefor at a rate equal to the rate
         payable under the Credit Agreement on Base Rate Advances during the
         continuance of a default in the repayment of Advances), whether or not
         such Guaranty Taxes were correctly or legally asserted; provided,
         however, that if the Lender subsequently recoups all or any part of
         such amount from the relevant taxation authority or other authority,
         then the Lender shall identify and remit the amount of the recoupment
         to such Guarantor within five Business Days after it receives the
         recoupment.

                  (c) Survival. Without prejudice to the survival of any other
         agreement of any Guarantor hereunder, the agreements and obligations of
         each Guarantor contained in this Section 3.8 shall survive the full and
         final payment and performance of the Guaranteed Obligations.

                  (d) Receipt. Within 30 days after the date of any payment of
         Guaranty Taxes by any Guarantor, such Guarantor shall furnish to the
         Lender a receipt for any Guaranty Taxes paid by such Guarantor pursuant
         to this Section 3.8.

                  SECTION III.9 No Waiver; Remedies. No failure on the part of
the Lender to exercise, and no delay in exercising, any right hereunder shall
operate as a waiver thereof, and no single or partial exercise of any right
hereunder shall preclude any other or further exercise of any other right or of
the same right as to any other matter or on a subsequent occasion.

                  SECTION III.10 Remedies Cumulative. All rights, powers and
remedies of the Lender under this Guaranty, under any other agreement now or at
any time hereafter in effect between the Lender and any Guarantor (whether
relating to the Guaranteed Obligations or otherwise) or now or hereafter
existing at law or in equity or by statute or otherwise, shall be cumulative and
concurrent and not alternative and each such right, power and remedy may be
exercised independently of, and in addition to, each other such right, power or
remedy.

                  SECTION III.11 Severally Enforceable. This Guaranty may be
enforced severally and successively by the Lender in one or more actions,
whether independent, concurrent, joint, successive or otherwise.

                  SECTION III.12 Counterparts. This Guaranty may be executed in
counterparts, and each such counterpart for all purposes shall be deemed an
original and all such counterparts together shall constitute but one and the
same agreement.

                  SECTION III.13 Severability. If any provision hereof or the
application thereof in any particular circumstance is held to be unlawful or
unenforceable in any respect, all other provisions hereof and such provision in
all other applications shall nevertheless remain effective and enforceable to
the maximum extent lawful.

                  SECTION III.14 Integration. This Guaranty and the other Loan
Documents to which any Guarantor is party are intended as an integrated and
final expression of the entire agreement of such Guarantor with respect to the
subject matter hereof and thereof. No representation, understanding, promise or
condition concerning the subject matter hereof and thereof shall be binding upon
the Lender unless expressed herein or therein, and no course of prior dealing or
usage of trade, and no parol or extrinsic evidence of any nature, shall be
admissible to supplement, modify or vary any of the terms hereof or thereof.
Acceptance of or acquiescence in a course of performance rendered under this
Guaranty or any other dealings between any Guarantor and the Lender shall not be
relevant to determine the meaning of this Guaranty even though the accepting or
acquiescing party had knowledge of the nature of the performance and opportunity
for objection.

                  SECTION III.15 GOVERNING LAW; SUBMISSION TO JURISDICTION;
WAIVER OF JURY TRIAL; WAIVER OF DAMAGES.

                  (a) GOVERNING LAW. THIS GUARANTY SHALL BE GOVERNED BY, AND
         CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF CALIFORNIA.

                  (b) SUBMISSION TO JURISDICTION. ANY LEGAL ACTION OR PROCEEDING
         WITH RESPECT TO THIS AGREEMENT MAY BE BROUGHT IN THE COURTS OF THE
         STATE OF CALIFORNIA OR OF THE UNITED STATES FOR THE NORTHERN DISTRICT
         OR THE CENTRAL DISTRICT OF CALIFORNIA, AND BY EXECUTION AND DELIVERY OF
         THIS GUARANTY, EACH PARTY HERETO CONSENTS, FOR ITSELF AND IN RESPECT OF
         ITS PROPERTY, TO THE JURISDICTION OF THOSE COURTS. EACH PARTY
         IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING ANY OBJECTION TO THE LAYING
         OF VENUE OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY
         NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY ACTION OR PROCEEDING IN
         SUCH JURISDICTION IN RESPECT OF THIS GUARANTY OR ANY DOCUMENT RELATED
         HERETO. SERVICE OF ANY SUMMONS, COMPLAINT OR OTHER PROCESS MAY BE MADE
         BY ANY MEANS PERMITTED BY CALIFORNIA LAW.

                  (c) WAIVER OF JURY TRIAL. EACH PARTY HERETO WAIVES ALL RIGHTS
         TO A TRIAL BY JURY OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR
         ARISING OUT OF OR RELATED TO THIS GUARANTY, THE OTHER LOAN DOCUMENTS OR

Party in collecting any such Claim or in retaking, holding, preparing for sale,
selling or otherwise disposing of or realizing on any Collateral or otherwise
exercising or enforcing any of its rights or remedies hereunder, together (in
each case) with Secured Party's reasonable attorneys' fees and disbursements and
court costs related thereto (collectively, the "Secured Obligations").

                  SECTION II.3 Delivery of Instruments. All stock certificates,

other lien notices), in form and substance reasonably satisfactory to Secured
Party, and take all other actions which are necessary or, in the reasonable good
faith judgment of Secured Party, desirable or appropriate to create, perfect,
protect or enforce Secured Party's security interests in the Collateral, to
enable Secured Party to exercise and enforce its rights and remedies hereunder
with respect to any Collateral, to protect the Collateral against the rights,
Claims or interests of third Persons or to effect or to assure further the
purposes and provisions of this Agreement, and the Grantor will pay all costs
related thereto and all reasonable expenses incurred by Secured Party in
connection therewith; provided, the foregoing shall not apply to Collateral that

Event of Default has not occurred.

interest granted hereby shall, (i) remain enforceable as security for all
Secured Obligations now outstanding or created or incurred at any future time
(whether or not created or incurred pursuant to any agreement presently in

the Secured Obligations or any other act, occurrence or event), until all
obligations of the Lender to extend credit to the Grantor have expired or been
terminated and all Secured Obligations have been fully and finally paid, (ii)
survive the expiration or termination of the Credit Agreement and the repayment
of the Advances to the same extent that any contingent Obligation survives, and
(iii) survive any sale, exchange or other disposition of the Grantor's interest
in any Collateral and remain enforceable against each transferee and subsequent
owner of such interest, unless such sale, exchange or other disposition is
permitted at the time under the Credit Agreement.

Secured Obligation is set aside, avoided, or rescinded or must otherwise be
restored or returned, this Agreement and the security interest created hereby
shall remain in full force and effect and, if previously released or terminated,
shall be automatically and fully reinstated, without any necessity for any act,
consent or agreement of the Grantor, as fully as if such payment had never been
made and as fully as if any such release or termination had never become
effective.

         any Claims owned by it are kept solely at the locations set forth in
         Schedules B hereto (other than (i) Inventory in transit in the ordinary
         course of business, (ii) Inventory temporarily held by contractors or
         agents in the ordinary course of business, and (iii) Inventory with an
         aggregate value of less than One Million Dollars ($1,000,000) held by
         consignees in the ordinary course of business).

                  (c) The Grantor does not do business, and for the previous
         five years has not done business, under any fictitious business names
         or trade names other than those listed on Schedule C hereto.

                  (d) The Grantor at all times is (or, as to any item of
         Collateral acquired after the date hereof, will be) the sole legal and
         beneficial owner of all Collateral reflected on its books and records
         as belonging to it and has exclusive possession and control thereof
         (except for Inventory (with an aggregate value of less than One Million
         Dollars ($1,000,000) in the possession of consignees, agents or
         contractors) free and clear of any Liens except those created by this
         Agreement or permitted under Section 5.3(a) of the Credit Agreement. No
         financing statement, notice of lien, mortgage, deed of trust or
         instrument similar in effect covering the Collateral or any portion
         thereof or any proceeds thereof exists or is on file in any public
         office, except as may have been filed in favor of Secured Party, and
         those relating to Liens permitted by the Credit Agreement.

                  (e) The Collateral has not been and will not be used or bought
         by the Grantor for personal, family or household purposes.

                  (f) All originals of all stock certificates, notes, bonds,
         debentures and other instruments constituting Collateral (except checks
         received and collected by the Grantor in the ordinary course of
         business) have been delivered to Secured Party with all necessary or
         appropriate endorsements.

                  (g) Except (i) as set forth in Schedule D and (ii) as to laws
         generally applicable to the creation, perfection or enforcement of
         security interests in personal property, neither the Grantor nor any of
         the Collateral purported to granted by it is subject to any requirement
         of law or contractual obligation which prohibits, restricts or limits
         the execution, delivery or performance of this Agreement or the
         creation, perfection or enforcement of the security interest purported
         to be created hereby.

                  (h) None of the Collateral constitutes "margin stock," as
         defined in Regulation U of the Board of Governors of the Federal
         Reserve System.

                  (k) The proper taxpayer identification number for the Grantor
         is accurately set forth on Schedule E.

                  (l) Grantor is the sole owner of the Intellectual Property
         Collateral listed below its name on Exhibits A, B and C to the
         Intellectual Property Security Agreement, except for non-exclusive
         licenses granted by Grantor in the ordinary course of business and
         except for the grant of licenses in connection with the settlement or
         enforcement of the Galley Litigation outside of the United States. Each
         of the Patents is valid and enforceable. No part of the Intellectual
         Property Collateral has been judged invalid or unenforceable, in whole
         or in part except for such Intellectual Property Collateral that the
         Grantor deems, in its reasonable business judgment, to be immaterial to
         the operation of Grantor's business and does not generate any of
         Grantor's accounts. No claim has been made that any part of the
         Intellectual Property Collateral violates the rights of any third party
         (it being understood that the Galley Litigation and the Litigation
         Adjustment shall not be deemed a breach of this representation). Except
         for and upon the filing with the United States Patent and Trademark
         Office with respect to the Patents and Trademarks and the Register of
         Copyrights with respect to the Copyrights necessary to perfect the
         security interests created hereunder, and except as has been already
         made or obtained, no authorization, approval or other action



                                       7

         by, and no notice to or filing with, any United States governmental
         authority or United States regulatory body is required either (i) for
         the grant by Grantor of the security interest granted hereby or for the
         execution, delivery or performance of Loan Documents by Grantor in the
         United States or (ii) for the perfection in the United States or the
         exercise by Secured Party of its rights and remedies hereunder.

                                   ARTICLE IV
                                    COVENANTS

                  SECTION IV.1 Covenants of Grantor. The Grantor covenants and
agrees that so long as the security interest created hereby remains outstanding:

                  (a) The Grantor will deliver to Secured Party each instrument
         included in the Collateral as set forth in Section 2.3.

                  (b) The Grantor will not (i) cause, permit or suffer any
         voluntary or involuntary change in its name, identity or corporate
         structure, or in the location of its chief executive office, and (ii)
         keep any tangible Collateral or any records relating to any Claim owned
         by it, or permit or suffer any such Collateral or records to be moved,
         to any location other than those specified in Schedule B (except with
         respect to (i) Inventory in transit in the ordinary course of business,
         (ii) Inventory temporarily held by contractors or agents in the
         ordinary course of business, and (iii) Inventory with an aggregate
         value of less than One Million Dollars ($1,000,000) held by consignees
         in the ordinary course of business) unless (in each case) (x) Schedule
         B has first been appropriately supplemented with respect thereto, and
         (y) an appropriate financing statement has been filed in the proper
         office and in the proper form, and all other requisite actions have
         been taken, to perfect or continue the perfection (without loss of
         priority) of Secured Party's security interest in the Collateral.

                  (c) The Grantor will defend the Collateral against all claims
         and demands of all Persons at any time claiming the same or any
         interest therein unless such interest is permitted hereunder and under
         the Credit Agreement.

                  (d) The Grantor will not encumber, sell, exchange or otherwise
         dispose of any item of Collateral or any interest therein, or permit or
         suffer any such item to be encumbered, sold, exchanged or otherwise
         disposed of, unless (i) such action is permitted at the time under the
         Credit Agreement and (ii) the Grantor makes all payments on account of
         the Obligations required to be made therefrom (provided that any such
         payments made in connection with any Asset Sale permitted under Section
         5.3(b)(iii) of the Credit Agreement shall be made concurrently with the
         closing of such Asset Sale), and the Grantor and each other Loan Party
         takes all other actions required to be taken in connection therewith,
         under the Credit Agreement, this Agreement or any other Loan Document.

                  (e) Secured Party is hereby authorized to file one or more
         financing statements, and continuations thereof and amendments thereto,
         relative to all or any part of the Collateral, without the signature of
         the Grantor where permitted by law.

                  (f) The Grantor will (i) maintain insurance as required in
         Section 5.2(g) of the Credit Agreement, (ii) give the Lender written
         notice of any default in the payment of premiums on such insurance
         policies and at least ten (10) days written notice prior to
         cancellation of any such policies, and (iii) cause the Lender to be
         named (A) as the principal beneficiary on any key-man life insurance
         policy, and (B) as an additional insured on a lender's loss payable
         endorsement, in a form satisfactory to the Lender for any other such
         insurance policies.

                  (g) Secured Party may at any time (but shall not be obligated
         to) (i) perform any of the obligations of the Grantor under this
         Agreement if the Grantor fails to perform such obligation within 30
         days (or, in the case of insurance, within 10 days) after written
         demand by Secured Party and (ii) make any payments and do any other
         acts it may deem reasonably necessary or desirable to protect its
         security interest in the Collateral, including, without limitation, the
         right to pay, purchase, contest or compromise any Lien that attaches or
         is asserted against any Collateral (other than Liens permitted under
         Section 5.3(a) of the Credit Agreement), to procure insurance required
         to be provided by the Grantor under the Credit Agreement, and to the
         extent the Grantor is required hereunder or under the Credit Agreement
         to do so, to appear in and defend any action or proceeding relating to
         the Collateral, if the Grantor fails to make such payments or perform
         such acts within 30 days after written demand by Secured Party, and the
         Grantor will promptly reimburse Secured Party for all payments made by
         Secured Party in doing so, together with interest thereon at the rate
         then applicable under the Credit Agreement to the Advances, and all
         costs and expenses related thereto as set forth in Section 8.10 hereof.

                  (h) Grantor shall give Secured Party prompt notice of any
         adverse material change in the composition of the Intellectual Property
         Collateral, including, but not limited to, any subsequent ownership
         right of the Grantor in or to any Copyright, Patent or Trademark not
         specified in any intellectual property security agreement between
         Grantor and Secured Party or knowledge of an event that materially
         adversely affects the value of the Intellectual Property Collateral.

                  (i) Grantor shall register or cause to be registered (to the
         extent not already registered) with the United States Patent and
         Trademark Office or the United States Copyright Office, as applicable,
         those intellectual property rights listed below its name on Exhibits A,
         B and C to the Intellectual Property Security Agreement delivered to
         Secured Party by Grantor in connection with this Agreement within
         thirty (30) days of the date of this Agreement. Grantor shall register
         or cause to be registered with the United States Patent and Trademark
         Office or the United States Copyright Office, as applicable, those
         additional United States Copyrights, Trademarks, Patents or maskworks
         developed or acquired by Grantor from time to time in connection with
         any product prior to the sale or licensing of such product to any third
         party, including without limitation revisions or additions to the
         intellectual property rights listed below its name on such Exhibits A,
         B and C but excluding Copyrights or Trademarks with respect to
         advertising.

                  (j) Grantor shall (i) protect, defend and maintain the
         validity and enforceability of the Trademarks, Patents and Copyrights
         unless the Grantor in good faith determines that such actions are not



                                       9
<PAGE>   98

         in the best interests of the Grantor and the failure to so act could
         not reasonably be expected to have a Material Adverse Change on the
         value of the Intellectual Property Collateral, (ii) use its
         commercially reasonable efforts to detect infringements of the
         Trademarks, Patents and Copyrights and promptly advise Secured Party in
         writing of material infringements detected and (iii) not allow any
         Trademarks, Patents or Copyrights to be abandoned, forfeited or
         dedicated to the public, without the written consent of Secured Party
         unless the Grantor determines in good faith that such abandonment or
         forfeiture is in the best interests of the Grantor and could not
         reasonably be expected to have a Material Adverse Change on the value
         of the Intellectual Property Collateral.

                  (k) Grantor shall not permit the inclusion in any material
         contract to which it becomes a party of any provisions that could or
         might in any way prevent the creation of a security interest in
         Grantor's rights and interests in any property included within the
         definition of the General Intangibles acquired under such contracts,
         except to the extent that such provisions are necessary in Grantor's
         exercise of its reasonable business judgement.


                                    ARTICLE V
                   VOTING RIGHTS, DIVIDENDS AND DISTRIBUTIONS

                  SECTION V.1 Voting Rights. So long as no Event of Default has
occurred and is continuing or would result from any exercise thereof, the
Grantor shall have and may exercise all voting rights with respect to any and
all shares of stock, equity securities and other equity, ownership or profit
interests constituting Collateral, except that:

                  (a) the Grantor may not and will not act or vote in favor of
         any action that would be or cause a breach of any obligations of the
         Grantor or any other Loan Party under the Credit Agreement or under any
         other Loan Document;

                  (b) the Grantor may not and will not act or vote in favor of
         (i) the authorization or issuance of any options, warrants, voting
         rights, or preference shares or additional shares, or (ii) any
         reclassification, readjustment, reorganization, merger, consolidation,
         sale or disposition of assets, or dissolution, without giving Secured
         Party at least 5 days' prior written notice thereof provided that for
         the conversion of Debt to equity permitted under Section 5.3(c)(ix) of
         the Credit Agreement, such notice period shall be limited to subsequent
         notice only; and

                  (c) the Grantor may not and will not act or vote in favor of
         any action that does or is reasonably likely to have a material adverse
         effect on the aggregate value of the Collateral provided that, for
         purposes of this Section 5.1(c), the effect of any such act or vote
         shall be determined with respect to the facts and circumstances at the
         time of such act or vote.

Upon the occurrence and during the continuance of an Event of Default, Secured
Party may (but shall not be obligated to) terminate the Grantor's right to
exercise voting rights with respect to any or all such shares of stock, equity
securities and ownership interests, either by giving written notice of such
termination to the Grantor or by



                                       10
<PAGE>   99

transferring such shares, securities or interests into Secured Party's name, and
Secured Party shall thereupon have the sole right and power to exercise such
voting rights.

                  SECTION V.2 Dividends, Distributions and Payments. So long as
no Event of Default has occurred and is continuing or would result, the Grantor
shall be entitled to receive all dividends and distributions on all shares of
stock, equity securities and other equity, ownership and profit interests
constituting Collateral and all payments on any notes, bonds, debentures and
other instruments constituting Collateral, so long as the Grantor makes all
payments on account of the Obligations required to be made therefrom, and the
Grantor and each other Loan Party takes all other actions required to be taken
in connection therewith, under the Credit Agreement, this Agreement or any other
Loan Document.

                                   ARTICLE VI
                              DEFAULTS AND REMEDIES

                  SECTION VI.1 Remedies. Upon and at any time after the
occurrence and during the continuance of any Event of Default, Secured Party may
exercise and enforce, in any order, (i) each and all of the rights and remedies
available to a secured party upon default under the Code or other applicable
law, (ii) each and all of the rights and remedies available to it, as Lender or
as Secured Party, under the Credit Agreement or any other Loan Document and
(iii) each and all of the following rights and remedies:

                  (a) Secured Party may notify any or all account debtors and
         obligors on any Collateral to make payment directly to Secured Party.

                  (b) Secured Party may take possession of all items of
         Collateral that are not then in its possession and require the Grantor
         or the Person in possession thereof to deliver such Collateral to
         Secured Party at one or more locations designated by Secured Party and
         reasonably convenient to it and the Grantor.

                  (c) Secured Party may sell, lease, license or otherwise
         dispose of any or all of the Collateral or any part thereof in one or
         more parcels at a public sale or in a private sale or transaction, on
         any exchange or market or at Secured Party's offices or on the
         Grantor's premises or at any other location, for cash, on credit or for
         future delivery, and may enter into all contracts necessary or
         appropriate in connection therewith, without any notice whatsoever
         unless required by law. The Grantor agrees that at least ten calendar
         days' written notice to the Grantor of the time and place of any public
         sale or the time after which any private sale is to be made shall be
         commercially reasonable. The giving of notice of any such sale or other
         disposition shall not obligate Secured Party to proceed with the sale
         or disposition, and any such sale or disposition may be postponed or
         adjourned from time to time, without further notice.

                  (d) Secured Party may, on a royalty-free basis, use and
         license use of any trademark, trade name, trade style, copyright,
         patent or technical knowledge or process owned, held or used by the
         Grantor in respect of any Collateral as to which any right or remedy of
         Secured Party is exercised or enforced.



                                       11
<PAGE>   100

In addition, each holder of any Secured Obligation may exercise and enforce such
rights and remedies for the collection of such Secured Obligation as may be
available to it by law or agreement.

                  SECTION VI.2 Remedies Cumulative. Secured Party may exercise
and enforce each right and remedy available to it upon the occurrence of an
Event of Default either before or concurrently with or after, and independently
of, any exercise or enforcement of any other right or remedy of Secured Party or
any holder of any Secured Obligation against any Person or property. All such
rights and remedies shall be cumulative, and no one of them shall exclude or
preclude any other.

                  SECTION VI.3 Surplus; Deficiency. Any surplus proceeds of any
sale or other disposition of Collateral by Secured Party remaining after all the
Secured Obligations are paid in full shall be paid over to the Grantor or to
whomever may be lawfully entitled to receive such surplus or as a court of
competent jurisdiction may direct, but if any obligation to make Advances then
remains outstanding or if any contingent, unliquidated or unmatured Secured
Obligation then remains outstanding, such surplus proceeds may be retained by
Secured Party and held as Collateral until such time as all such obligations
have expired or been terminated and all outstanding Secured Obligations have
been determined, liquidated, paid in full and discharged. The Grantor shall be
and remain liable for any deficiency.

                  SECTION VI.4 Information Related to Collateral. If Secured
Party determines to sell or otherwise dispose of any Collateral, the Grantor
shall, and shall cause any Person controlled by it to, furnish to Secured Party
all information Secured Party may request that pertains or could pertain to the
value or condition of such Collateral or would or might facilitate its sale.

                  SECTION VI.5 Sale Exempt from Registration. Secured Party
shall be entitled at any sale or other disposition of Collateral, if it deems it
advisable to do so, to restrict the prospective bidders or purchasers to persons
who will provide assurances satisfactory to Secured Party that they may be
offered and sold the Collateral to be sold without registration under the
Securities Act of 1933, as amended (the "Securities Act"), or any other
applicable state or federal statute, and upon the consummation of any such sale,
Secured Party shall have the right to assign, transfer and deliver to the
purchaser or purchasers thereof the Collateral so sold. Secured Party may
solicit offers to buy the Collateral, or any part of it, from a limited number
of investors deemed by Secured Party, in its commercially reasonable judgment,
to meet the requirements to purchase securities under Regulation D promulgated
under the Securities Act as then in effect (or any other regulation of similar
import). If Secured Party solicits such offers from such investors, then the
acceptance by Secured Party of the highest offer obtained therefrom shall be
deemed to be a commercially reasonable method of disposition of such Collateral.

                  SECTION VI.6 Registration Rights. During the continuance of an
Event of Default, if Secured Party determines that registration of any
securities constituting Collateral under the Securities Act or other applicable
law is required or desirable in connection with any sale, the Grantor will use
its best efforts to cause such registration to be effectively made, at no
expense to Secured Party, and to continue any such registration effective for
such time as may be reasonably necessary in the opinion of the Secured Party.

                                   ARTICLE VII

                                THE SECURED PARTY

                  SECTION VII.1 Credit Agreement Provisions. Secured Party is
executing and delivering this Agreement, and accepting the security interests,
rights, remedies, powers and benefits conferred upon Secured Party hereby, as
Lender under the Credit Agreement. The provisions of Article VII of the Credit
Agreement and all rights, powers, immunities and indemnities granted to the
Lender under the Credit Agreement and other Loan Documents shall apply in
respect of such execution, delivery and acceptance and in respect of any and all
actions taken or omitted by Secured Party under, in connection with or with
respect to this Agreement.

                  SECTION VII.2 No Liability. Secured Party makes no statement,
promise, representation or warranty whatsoever, and shall have no liability
whatsoever, to any holder of any Secured Obligations as to the authorization,
execution, delivery, legality, enforceability or sufficiency of this Agreement
or as to the creation, perfection, priority or enforceability of any security
interest granted hereunder or as to existence, ownership, quality, condition,
value or sufficiency of any Collateral or as to any other matter whatsoever.

                  SECTION VII.3 Duty of Care. Neither Secured Party nor any
director, officer, employee, attorney or agent of Secured Party shall be
obligated to care for the Collateral hereunder or to collect, enforce, vote or
protect the Collateral or any rights or interests of the Grantor related thereto
or to preserve or enforce any rights which the Grantor or any other Person may
have against any third party, except only that Secured Party shall exercise
reasonable care in physically safekeeping any item of Collateral that was
delivered into Secured Party's possession. Secured Party shall be deemed to have
exercised such reasonable care if the Collateral is accorded treatment
substantially equal to that which Secured Party accords to its own property or
if it selects, with reasonable care, a custodian or agent to hold such
collateral for Secured Party's account.

                                  ARTICLE VIII
                            MISCELLANEOUS PROVISIONS

                  SECTION VIII.1 Notices. All notices, requests, approvals,
consents and other communications required or permitted to be made hereunder
shall, except as otherwise provided, be given in the manner specified and to the
addresses set forth in Section 7.2 of the Credit Agreement.

                  SECTION VIII.2 Headings. The various headings in this
Agreement are inserted for convenience only and shall not affect the meaning or
interpretation of this Agreement or any provision hereof.

                  SECTION VIII.3 Changes. This Agreement or any provision hereof
may be changed, waived or terminated only by a statement in writing signed by

or protecting a Claim in respect of any such debts, liabilities and obligations
or the Collateral in any bankruptcy case or insolvency proceeding to which the
Grantor or any other Loan Party may be party and all collection costs and
enforcement expenses incurred by Secured Party in collecting any such Claim or
in retaking, holding, preparing for sale, selling or otherwise disposing of or
realizing on any Collateral or otherwise exercising or enforcing any of its
rights or remedies hereunder, together (in each case) with Secured Party's
reasonable attorneys' fees and disbursements and court costs related thereto
(collectively, the "Secured Obligations").

                  SECTION II.3 Delivery of Instruments. All stock certificates,
notes, bonds, debentures and other instruments constituting the Collateral
(except checks received and collected in the ordinary course of business) shall
be delivered to and held by Secured Party on the date hereof or, if hereafter
acquired, promptly, and, in any case, no later than five (5) days, after or upon
acquisition thereof by any Grantor and without any notice from or demand by
Secured Party, in each case in suitable form for transfer by delivery or
accompanied by duly executed instruments of transfer or assignments in blank or
with appropriate endorsements, in form and substance reasonably satisfactory to
Secured Party.

                  SECTION II.4 Further Assurances. Each Grantor will promptly
(and in no event later than five days after request by Secured Party) execute
and deliver, and use its reasonable and diligent best efforts to obtain from
other Persons, all instruments and documents (including, without limitation,
assignments, transfer documents and transfer notices, financing statements and
other lien notices), in form and substance reasonably satisfactory to Secured
Party, and take all other actions which are necessary or, in the reasonable good
faith judgment of Secured Party, desirable or appropriate to create, perfect,
protect or enforce Secured Party's security interests in the Collateral, to
enable Secured Party to exercise and enforce its rights and remedies hereunder
with respect to any Collateral, to protect the Collateral against the rights,
Claims or interests of third Persons or to effect or to assure further the
purposes and provisions of this Agreement, and the Grantor will pay all costs
related thereto and all

reasonable expenses incurred by Secured Party in connection therewith; provided,
the foregoing shall not apply to Collateral that is Inventory with an aggregate
value of less than One Million Dollars ($1,000,000) held by consignees in the
ordinary course of business so long as an Event of Default has not occurred.

                  SECTION II.5 Survival of Security Interest. Except as
otherwise required by law, the security interest granted hereby shall, (i)
remain enforceable as security for all Secured Obligations now outstanding or
created or incurred at any future time (whether or not created or incurred
pursuant to any agreement presently in effect or hereafter made and
notwithstanding any subsequent repayment of any of the Secured Obligations or
any other act, occurrence or event), until all obligations of the Lender to
extend credit to the Grantor have expired or been terminated and all Secured
Obligations have been fully and finally paid, (ii) survive the expiration or
termination of the Credit Agreement and the repayment of the Advances to the
same extent that any contingent Obligation survives, and (iii) survive any sale,
exchange or other disposition of the Grantor's interest in any Collateral and
remain enforceable against each transferee and subsequent owner of such
interest, unless such sale, exchange or other disposition is permitted at the
time under the Credit Agreement.

                  SECTION II.6 Reinstatement. If at any time any payment on any
Secured Obligation is set aside, avoided, or rescinded or must otherwise be
restored or returned, this Agreement and the security interest created hereby
shall remain in full force and effect and, if previously released or terminated,
shall be automatically and fully reinstated, without any necessity for any act,
consent or agreement of any Grantor, as fully as if such payment had never been
made and as fully as if any such release or termination had never become
effective.

                                   ARTICLE III
                         REPRESENTATIONS AND WARRANTIES

                  SECTION III.1 Representations and Warranties of Grantors. Each
Grantor represents and warrants that:

                  (a) Schedule A completely and accurately sets forth all shares
         of stock, and all other equity, ownership and profit interests in which
         the Grantor owns any interest. The Pledged Shares have been duly
         authorized and validly issued, are fully paid and non-assessable and
         were not issued in breach or derogation of preemptive rights of any
         Person.

                  (b) The Grantor's chief executive office is located at the
         address shown as the chief executive office on Schedule B hereto. The
         Grantor has no places of business other than its chief executive office
         and the other locations set forth on Schedule B. All tangible
         Collateral, except instruments and stock certificates delivered to
         Secured Party in pledge, and all of the Grantor's records relating to
         any Claims owned by it are kept solely at the locations set forth in
         Schedules B hereto (other than (i) Inventory in transit in the ordinary
         course of business, (ii) Inventory temporarily held by contractors or
         agents in the ordinary course of business, and (iii) Inventory with an
         aggregate value of less than One Million Dollars ($1,000,000) held by
         consignees in the ordinary course of business).

                  (c) The Grantor does not do business, and for the previous
         five years has not done business, under any fictitious business names
         or trade names other than those listed on Schedule C hereto.




                                      B-3-6

<PAGE>   113

                  (d) The Grantor at all times is (or, as to any item of
         Collateral acquired after the date hereof, will be) the sole legal and
         beneficial owner of all Collateral reflected on its books and records
         as belonging to it and has exclusive possession and control thereof
         (except for Inventory with an aggregate value of less than One Million
         Dollars ($1,000,000) in the possession of consignees, agents or
         contractors) free and clear of any Liens except those created by this
         Agreement or permitted under Section 5.3(a) of the Credit Agreement. No
         financing statement, notice of lien, mortgage, deed of trust or
         instrument similar in effect covering the Collateral or any portion
         thereof or any proceeds thereof exists or is on file in any public
         office, except as may have been filed in favor of Secured Party those
         relating to Liens permitted by the Credit Agreement.

                  (e) The Collateral has not been and will not be used or bought
         by the Grantor for personal, family or household purposes.

                  (f) All originals of all stock certificates, notes, bonds,
         debentures and other instruments constituting Collateral (except checks
         received and collected by the Grantor in the ordinary course of
         business) have been delivered to Secured Party with all necessary or
         appropriate endorsements.

                  (g) Except (i) as set forth in Schedule D and (ii) as to laws
         generally applicable to the creation, perfection or enforcement of
         security interests in personal property, neither the Grantor nor any of
         the Collateral purported to granted by it is subject to any requirement
         of law or contractual obligation which prohibits, restricts or limits
         the execution, delivery or performance of this Agreement or the
         creation, perfection or enforcement of the security interest purported
         to be created hereby.

                  (h) None of the Collateral constitutes "margin stock," as
         defined in Regulation U of the Board of Governors of the Federal
         Reserve System.

                  (k) The proper taxpayer identification number for the Grantor
         is accurately set forth on Schedule E.

                  (l) Grantor is the sole owner of the Intellectual Property
         Collateral listed below its name on Exhibits A, B and C to the
         Intellectual Property Security Agreement, except for non-exclusive
         licenses granted by Grantor in the ordinary course of business and
         except for the grant of licenses in connection with the settlement or
         enforcement of the Galley Litigation outside of the United States. Each
         of the Patents is valid and enforceable. No part of the Intellectual
         Property Collateral has been judged invalid or unenforceable, in whole
         or in part except for such Intellectual Property Collateral that the
         Grantor deems, in its reasonable business judgment, to be immaterial to
         the operation of Grantor's business and does not generate any of
         Grantor's accounts. No claim has been made that any part of the
         Intellectual Property Collateral violates the rights of any third party
         (it being understood that the Galley Litigation and the Litigation
         Adjustment shall not be deemed a breach of this representation). Except
         for and upon the filing with the United States Patent and Trademark
         Office with respect to the Patents and Trademarks and the Register of
         Copyrights with respect to the Copyrights necessary to perfect the
         security interests created hereunder, and except as has been already
         made or obtained, no authorization, approval or other action by, and no
         notice to or filing with, any United States governmental authority or
         United States regulatory

         body is required either (i) for the grant by Grantor of the security
         interest granted hereby or for the execution, delivery or performance
         of Loan Documents by Grantor in the United States or (ii) for the
         perfection in the United States or the exercise by Secured Party of its
         rights and remedies hereunder.


                                   ARTICLE IV
                                    COVENANTS

                  SECTION IV.1 Covenants of Grantors. Each Grantor covenants and
agrees that so long as the security interest created hereby remains outstanding:

                  (a) The Grantor will deliver to Secured Party each instrument
         included in the Collateral as set forth in Section 2.3.

                  (b) The Grantor will not (i) cause, permit or suffer any
         voluntary or involuntary change in its name, identity or corporate
         structure, or in the location of its chief executive office, and (ii)
         keep any tangible Collateral or any records relating to any Claim owned
         by it, or permit or suffer any such Collateral or records to be moved,
         to any location other than those specified in Schedule B (except with
         respect to (i) Inventory in transit in the ordinary course of business,
         (ii) Inventory temporarily held by contractors or agents in the
         ordinary course of business, and (iii) Inventory with an aggregate
         value of less than One Million Dollars ($1,000,000) held by consignees
         in the ordinary course of business) unless (in each case) (x) Schedule
         B has first been appropriately supplemented with respect thereto, and
         (y) an appropriate financing statement has been filed in the proper
         office and in the proper form, and all other requisite actions have
         been taken, to perfect or continue the perfection (without loss of
         priority) of Secured Party's security interest in the Collateral.

                  (c) The Grantor will defend the Collateral against all claims
         and demands of all Persons at any time claiming the same or any
         interest therein unless such interest is permitted hereunder and under
         the Credit Agreement.

                  (d) The Grantor will not encumber, sell, exchange or otherwise
         dispose of any item of Collateral or any interest therein, or permit or
         suffer any such item to be encumbered, sold, exchanged or otherwise
         disposed of, unless (i) such action is permitted at the time under the
         Credit Agreement and (ii) the Grantor makes all payments on account of
         the Obligations required to be made therefrom (provided that any such
         payments made in connection with any Asset Sale permitted under Section
         5.3(b)(iii) of the Credit Agreement shall be made concurrently with the
         closing of such Asset Sale), and the Grantor and each other Loan Party
         takes all other actions required to be taken in connection therewith,
         under the Credit Agreement, this Agreement or any other Loan Document.

                  (e) Secured Party is hereby authorized to file one or more
         financing statements, and continuations thereof and amendments thereto,
         relative to all or any part of the Collateral, without the signature of
         the Grantor where permitted by law.




                                      B-3-8

<PAGE>   115

                  (f) The Grantor will (i) maintain insurance as required in
         Section 5.2(g) of the Credit Agreement, (ii) give the Lender written
         notice of any default in the payment of premiums on such insurance
         policies and at least ten (10) days written notice prior to
         cancellation of any such policies, and (iii) cause the Lender to be
         named (A) as the principal beneficiary on any key-man life insurance
         policy and (B) as an additional insured on a lender's loss payable
         endorsement, in a form satisfactory to the Lender, for any other such
         insurance policies.

                  (g) Secured Party may at any time (but shall not be obligated
         to) (i) perform any of the obligations of the Grantor under this
         Agreement if the Grantor fails to perform such obligation within 30
         days (or, in the case of insurance, within 10 days) after written
         demand by Secured Party and (ii) make any payments and do any other
         acts it may deem reasonably necessary or desirable to protect its
         security interest in the Collateral, including, without limitation, the
         right to pay, purchase, contest or compromise any Lien that attaches or
         is asserted against any Collateral (other than Liens permitted under
         Section 5.3(a) of the Credit Agreement), to procure insurance required
         to be provided by the Grantor under the Credit Agreement, and, to the
         extent the Grantor is required hereunder or under the Credit Agreement
         to do so, to appear in and defend any action or proceeding relating to
         the Collateral, if the Grantor fails to make such payments or perform
         such acts within 30 days after written demand by Secured Party and the
         Grantor will promptly reimburse Secured Party for all payments made by
         Secured Party in doing so, together with interest thereon at the rate
         then applicable under the Credit Agreement to the Advances, and all
         costs and expenses related thereto as set forth in Section 8.10 hereof.

                  (h) Grantor shall give Secured Party prompt notice of any
         material adverse change in the composition of the Intellectual Property
         Collateral, including, but not limited to, any subsequent ownership
         right of Grantor in or to any Copyright, Patent or Trademark not
         specified in any intellectual property security agreement between
         Grantor and Secured Party or knowledge of an event that materially
         adversely affects the value of the Intellectual Property Collateral.

                  (i) Grantor shall register or cause to be registered (to the
         extent not already registered) with the United States Patent and
         Trademark Office or the United States Copyright Office, as applicable,
         those intellectual property rights listed below on Exhibits A, B and C
         to the Intellectual Property Security Agreement delivered to Secured
         Party by Grantor in connection with this Agreement within thirty (30)
         days of the date of this Agreement. Grantor shall timely register or
         cause to be registered with the United States Patent and Trademark
         Office or the United States Copyright Office, as applicable, those
         additional United States Copyrights, Trademarks, Patents or maskworks
         developed or acquired by Grantor from time to time in connection with
         any product prior to the sale or licensing of such product to any third
         party, including without limitation revisions or additions to the
         intellectual property rights listed on Exhibits A, B and C but
         excluding Copyrights or Trademarks with respect to advertising.

                  (j) Grantor shall (i) protect, defend and maintain the
         validity and enforceability of the Trademarks, Patents and Copyrights
         unless the Grantor in good faith determines that such actions are not
         in the best interests of the Grantor and the failure to so act could
         not reasonably be expected to have a Material Adverse Change on the
         value of the Intellectual Property Collateral, (ii) use its
         commercially reasonable efforts to detect infringements of the
         Trademarks, Patents and Copyrights and promptly advise




                                      B-3-9

<PAGE>   116

         Secured Party in writing of material infringements detected and (iii)
         not allow any Trademarks, Patents or Copyrights to be abandoned,
         forfeited or dedicated to the public without the written consent of
         Secured Party unless the Grantor determines in good faith that such
         abandonment or forfeiture is in the best interests of the Grantor and
         could not reasonably be expected to have a Material Adverse Change on
         the value of the Intellectual Property Collateral.

                  (k) Grantor shall not permit the inclusion in any material
         contract to which it becomes a party of any provisions that could or
         might in any way prevent the creation of a security interest in
         Grantor's rights and interests in any property included within the
         definition of the General Intangibles acquired under such contracts,
         except to the extent that such provisions are necessary in Grantor's
         exercise of its reasonable business judgement.


                                    ARTICLE V
                   VOTING RIGHTS, DIVIDENDS AND DISTRIBUTIONS

                  SECTION V.1 Voting Rights. So long as no Event of Default has
occurred and is continuing or would result from any exercise thereof, each
Grantor shall have and may exercise all voting rights with respect to any and
all shares of stock, equity securities and other equity, ownership or profit
interests constituting Collateral, except that:

                  (a) the Grantor may not and will not act or vote in favor of
         any action that would be or cause a breach of any obligations of the
         Grantor or any other Loan Party under the Credit Agreement or under any
         other Loan Document;

                  (b) the Grantor may not and will not act or vote in favor of
         (i) the authorization or issuance of any options, warrants, voting
         rights, or preference shares or additional shares, or (ii) any
         reclassification, readjustment, reorganization, merger, consolidation,
         sale or disposition of assets, or dissolution, without giving Secured
         Party at least 15 days' prior written notice thereof; and

                  (c) the Grantor may not and will not act or vote in favor of
         any action that does or is reasonably likely to have a material adverse
         effect on the aggregate value of the Collateral provided that, for
         purposes of this Section 5.1(c), the effect of any such act or vote
         shall be determined with respect to the facts and circumstances at the
         time of such act or vote.

Upon the occurrence and during the continuance of an Event of Default, Secured
Party may (but shall not be obligated to) terminate the Grantor's right to
exercise voting rights with respect to any or all such shares of stock, equity
securities and ownership interests, either by giving written notice of such
termination to the Grantor or by transferring such shares, securities or
interests into Secured Party's name, and Secured Party shall thereupon have the
sole right and power to exercise such voting rights.

                  SECTION V.2 Dividends, Distributions and Payments. So long as
no Event of Default has occurred and is continuing or would result, the Grantors
shall be entitled to receive all dividends and distributions on all shares of
stock, equity securities and other equity, ownership and profit interests
constituting Collateral and




                                     B-3-10

<PAGE>   117

all payments on any notes, bonds, debentures and other instruments constituting
Collateral, so long as the Grantors make all payments on account of the
Obligations required to be made therefrom, and the Grantors and each other Loan
Party takes all other actions required to be taken in connection therewith,
under the Credit Agreement, this Agreement or any other Loan Document.


                                   ARTICLE VI
                              DEFAULTS AND REMEDIES

                  SECTION VI.1 Remedies. Upon and at any time after the
occurrence and during the continuance of any Event of Default, Secured Party may
exercise and enforce, in any order, (i) each and all of the rights and remedies
available to a secured party upon default under the Code or other applicable
law, (ii) each and all of the rights and remedies available to it, as Lender or
as Secured Party, under the Credit Agreement or any other Loan Document and
(iii) each and all of the following rights and remedies:

                  (a) Secured Party may notify any or all account debtors and
         obligors on any Collateral to make payment directly to Secured Party.

                  (b) Secured Party may take possession of all items of
         Collateral that are not then in its possession and require the Grantors
         or the Person in possession thereof to deliver such Collateral to
         Secured Party at one or more locations designated by Secured Party and
         reasonably convenient to it and the Grantors.

                  (c) Secured Party may sell, lease, license or otherwise
         dispose of any or all of the Collateral or any part thereof in one or
         more parcels at a public sale or in a private sale or transaction, on
         any exchange or market or at Secured Party's offices or on the
         Grantor's premises or at any other location, for cash, on credit or for
         future delivery, and may enter into all contracts necessary or
         appropriate in connection therewith, without any notice whatsoever
         unless required by law. The Grantors agree that at least ten calendar
         days' written notice to the Grantor of the time and place of any public
         sale or the time after which any private sale is to be made shall be
         commercially reasonable. The giving of notice of any such sale or other
         disposition shall not obligate Secured Party to proceed with the sale
         or disposition, and any such sale or disposition may be postponed or
         adjourned from time to time, without further notice.

                  (d) Secured Party may, on a royalty-free basis, use and
         license use of any trademark, trade name, trade style, copyright,
         patent or technical knowledge or process owned, held or used by the
         Grantor in respect of any Collateral as to which any right or remedy of
         Secured Party is exercised or enforced.

In addition, Secured Party may exercise and enforce such rights and remedies for
the collection of any Secured Obligation as may be available to it by law or
agreement.

                  SECTION VI.2 Remedies Cumulative. Secured Party may exercise
and enforce each right and remedy available to it upon the occurrence of an
Event of Default either before or concurrently with or after, and




                                     B-3-11

<PAGE>   118

independently of, any exercise or enforcement of any other right or remedy of
Secured Party against any Person or property. All such rights and remedies shall
be cumulative, and no one of them shall exclude or preclude any other.

                  SECTION VI.3 Surplus; Deficiency. Any surplus proceeds of any
sale or other disposition of Collateral by Secured Party remaining after all the
Secured Obligations are paid in full shall be paid over to the Grantors or to
whomever may be lawfully entitled to receive such surplus or as a court of
competent jurisdiction may direct, but if any obligation to make Advances then
remains outstanding or if any contingent, unliquidated or unmatured Secured
Obligation then remains outstanding, such surplus proceeds may be retained by
Secured Party and held as Collateral until such time as all such obligations
have expired or been terminated and all outstanding Secured Obligations have
been determined, liquidated, paid in full and discharged. The Grantors shall be
and remain liable for any deficiency.

                  SECTION VI.4 Information Related to Collateral. If Secured
Party determines to sell or otherwise dispose of any Collateral, the Grantor
shall, and shall cause any Person controlled by it to, furnish to Secured Party
all information Secured Party may request that pertains or could pertain to the
value or condition of such Collateral or would or might facilitate its sale.

                  SECTION VI.5 Sale Exempt from Registration. Secured Party
shall be entitled at any sale or other disposition of Collateral, if it deems it
advisable to do so, to restrict the prospective bidders or purchasers to persons
who will provide assurances satisfactory to Secured Party that they may be
offered and sold the Collateral to be sold without registration under the
Securities Act of 1933, as amended (the "Securities Act"), or any other
applicable state or federal statute, and upon the consummation of any such sale,
Secured Party shall have the right to assign, transfer and deliver to the
purchaser or purchasers thereof the Collateral so sold. Secured Party may
solicit offers to buy the Collateral, or any part of it, from a limited number
of investors deemed by Secured Party, in its commercially reasonable judgment,
to meet the requirements to purchase securities under Regulation D promulgated
under the Securities Act as then in effect (or any other regulation of similar
import). If Secured Party solicits such offers from such investors, then the
acceptance by Secured Party of the highest offer obtained therefrom shall be
deemed to be a commercially reasonable method of disposition of such Collateral.

                  SECTION VI.6 Registration Rights. During the continuance of an
Event of Default, if Secured Party determines that registration of any
securities constituting Collateral under the Securities Act or other applicable
law is required or desirable in connection with any sale, the Grantors will use
their best efforts to cause such registration to be effectively made, at no
expense to Secured Party, and to continue any such registration effective for
such time as may be reasonably necessary in the opinion of the Secured Party.

or to preserve or enforce any rights which the Grantor or any other Person may

         This Intellectual Property Security Agreement is made as of October 30,
1996 by O.S.I. CORPORATION, a California corporation ("OSI") and each other
entity that is identified on the signature pages hereof or that hereafter
executes and delivers a Subsidiary Joinder in substantially the form set forth

BANK-CALIFORNIA, a California chartered bank, as the Lender (the "Lender").

                                    RECITALS

         A. OSI and Lender entered into Credit Agreement, dated of even date
herewith (as amended, supplemented or otherwise modified from time to time, the
"Credit Agreement").

         B. Each Grantor, other than OSI, is a direct or indirect subsidiary of
OSI and expects to derive substantial direct and indirect benefit from the
transactions contemplated by the Credit Agreement. Each Grantor, other than OSI,
has entered into a Subsidiary Guaranty (or a Subsidiary Joinder thereto) dated
of even date herewith, in favor of Lender.

         C. OSI has entered into a Borrower Pledge and Security Agreement, dated
of even date herewith, in favor of the Lender. Each Grantor, other than OSI, has
entered into a Subsidiary Pledge and Security Agreement (or a Subsidiary Joinder
thereto), dated of even date herewith in favor of the Lender.

         D. It is a condition precedent to the extension of credit under the
Credit Agreement that each Grantor shall have granted the security interests
described herein as security for each and all the Secured Obligations (as that
term is defined in the Pledge and Security Agreements) and as security for the
other debts, liabilities and obligations secured hereunder.

                  NOW, THEREFORE, in consideration of the foregoing and in order
to induce the Lender to extend credit under the Credit Agreement, each Grantor
hereby agrees as follows:

                                    AGREEMENT

         To secure the Secured Obligations (as defined in the Pledge and
Security Agreements), each Grantor grants and pledges to Lender a security
interest in all of such Grantor's right, title and interest in, to and under its
Intellectual Property Collateral (including without limitation those Copyrights,
Patents and Trademarks listed on Schedules A, B and C hereto), and including
without limitation all proceeds thereof (such as, by way of example but not by
way of limitation, license royalties and proceeds of infringement suits), the
right to sue for past, present and future infringements, all rights
corresponding thereto throughout the world and all reissues, divisions
continuations, renewals, extensions and continuations-in-part thereof.

         This security interest is granted in conjunction with the security
interest granted to Lender



                                       1

under the Pledge and Security Agreements. The rights and remedies of Lender with
respect to the security interest granted hereby are in addition to those set
forth in the Pledge and Security Agreements and the other Loan Documents, and
those which are now or hereafter available to Lender as a matter of law or
equity. Each right, power and remedy of Lender provided for herein or in the
Pledge and Security Agreements or any of the Loan Documents, or now or hereafter
existing at law or in equity shall be cumulative and concurrent and shall be in
addition to every right, power or remedy provided for herein and the exercise by
Lender of any one or more of the rights, powers or remedies provided for in this
Intellectual Property Security Agreement, the Credit Agreement or any of the
other Loan Documents, or now or hereafter existing at law or in equity, shall
not preclude the simultaneous or later exercise by any person, including Lender,
of any or all other rights, powers or remedies.

         IN WITNESS WHEREOF, the parties have cause this Intellectual Property
Security Agreement to be duly executed by its officers thereunto duly authorized
as of the first date written above.

                             SUBORDINATION AGREEMENT




                  This SUBORDINATION AGREEMENT (the "Agreement"), dated as of
October 30, 1996, is made by JOHN D. FRUTH (the "Subordinated Creditor"), in
favor of COMERICA BANK-CALIFORNIA, a California chartered bank (the "Lender"),
as Lender under the Credit Agreement (defined below).

                                    RECITALS

                  A. O.S.I. Corporation, a California Corporation (the
"Borrower") has entered into that certain Credit Agreement, dated as of October
30, 1996 (as amended, supplemented or otherwise modified from time to time (the
"Credit Agreement"), by and between the Borrower and the Lender.

                  B. The Subordinated Creditor has extended loans or other
credit accommodations to the Borrower, including such debt as evidenced by a
Junior Subordinated Promissory Note by the Borrower dated November 1, 1996 in
the principal amount of $2,894,649 in favor of the Subordinated Creditor, the
Borrower (the "Fruth Note"), and/or may extend loans or other credit
accommodations to the Borrower from time to time.

                  C. In order to induce the Lender to extend credit to the
Borrower under the Credit Agreement, and, at any time or from time to time, at
the Lender's option, to make such further loans, extensions of credit, or other
accommodations to or for the account of the Borrower, or to purchase or extend
credit upon any instrument or writing in respect of which the Borrower may be
liable in any capacity, or to grant such renewals or extension of any such loan,
extension of credit, purchase, or other accommodation as the Lender may deem
advisable, the Subordinated Creditor is willing to subordinate: (i) all of the
Borrower's indebtedness and obligations to the Subordinated Creditor due and
owing under the Fruth Note, whether presently existing or arising in the future
(the "Subordinated Debt"), to all of the Borrower's indebtedness and obligations
to the Lender, including, but not limited to, those amounts due and owing under
the Credit Agreement, whether presently existing or arising in the future; and
(ii) all of the Subordinated Creditor's security interests, if any, to all of
the Lender's security interests in the Borrower's property.

to induce the Lender to extend credit under the Credit Agreement, the
Subordinated Creditor hereby agrees as follows:



                                        1

<PAGE>   136

         1. The Subordinated Creditor subordinates to the Lender any security
interest or lien that the Subordinated Creditor may have in any property of the
Borrower. Notwithstanding the respective dates of attachment or perfection of
the security interest of the Subordinated Creditor and the security interest of
the Lender, the security interest of the Lender in the Collateral, as defined in
the Credit Agreement, shall at all times be prior to the security interest of
the Subordinated Creditor.

         2. All Subordinated Debt is subordinated in right of payment to all
obligations of the Borrower to the Lender now existing or hereafter arising,
together with all costs of collecting such obligations (including attorneys'
fees), including, without limitation, all interest accruing after the
commencement by or against the Borrower of any bankruptcy, reorganization or
similar proceeding, and all obligations under the Credit Agreement (the "Senior
Debt").

         3. The Subordinated Creditor will not demand or receive from the
Borrower (and the Borrower will not pay to the Subordinated Creditor) all or any
part of the Subordinated Debt, by way of payment, prepayment, setoff, lawsuit or
otherwise, nor will the Subordinated Creditor exercise any remedy with respect
to the Collateral, nor will the Subordinated Creditor commence, or cause to
commence, prosecute or participate in any administrative, legal or equitable
action against the Borrower, for so long as any portion of the Senior Debt
remains outstanding. The foregoing notwithstanding, the Subordinated Creditor
shall be entitled (i) to receive each regularly scheduled payment of interest
that constitutes Subordinated Debt or (ii) to credit the principal amount of
amounts due and owing under the Fruth Note to the option exercise price of stock
options held and exercised by John D. Fruth as provided under the Fruth Note,
provided that an Event of Default, as defined in the Credit Agreement, has not
occurred and is not continuing and would not exist immediately after such
payment.

         4. The Subordinated Creditor shall promptly deliver to the Lender in
the form received (except for endorsement or assignment by the Subordinated
Creditor where required by the Lender) for application to the Senior Debt any
payment, distribution, security or proceeds received by the Subordinated
Creditor with respect to the Subordinated Debt other than in accordance with
this Agreement.

         5. In the event of the Borrower's insolvency, reorganization or any
case or proceeding under any bankruptcy or insolvency law or laws relating to
the relief of debtors, these provisions shall remain in full force and effect,
and the Lender's claims against the Borrower and the estate of the Borrower
shall be paid in full before any payment is made to the Subordinated Creditor.

         6. For so long as any of the Senior Debt remains unpaid, the
Subordinated Creditor irrevocably appoints the Lender as the Subordinated
Creditor's attorney-in-fact, and grants to the Lender a power of attorney with
full power of substitution, in the name of the Subordinated Creditor or in the
name of the Lender, for the use and benefit of the Lender, with subsequent
notice as soon as reasonably practical to the Subordinated Creditor, to perform
at the Lender's option the following acts in any bankruptcy, insolvency or
similar proceeding involving the Borrower:




                                        2

<PAGE>   137
                  (i) To file the appropriate claim or claims in respect of the
Subordinated Debt on behalf of the Subordinated Creditor if the Subordinated
Creditor does not do so prior to 30 days before the expiration of the time to
file claims in such proceeding and if the Lender elects, in its sole discretion,
to file such claim or claims; and

                  (ii) In the event that the Subordinated Creditor does not
comply with Section 7 herein, to accept or reject any plan of reorganization or
arrangement on behalf of the Subordinated Creditor and to otherwise vote the
Subordinated Creditor's claims in respect of any Subordinated Debt in any manner
that the Lender deems appropriate for the enforcement of its rights hereunder;

         7. The Subordinated Creditor shall not vote to accept a plan of
reorganization, propose a plan of reorganization or arrangement or otherwise act
or vote the Subordinated Creditor's claim in respect of any Subordinated Debt in
any manner that furthers or supports a plan of reorganization that does not
provide that the Lender will be paid all Senior Debt either (i) in cash in full
at the time of the confirmation of such plan or (ii) under the specific terms
(including, but not limited to, payment and interest rate terms) provided in the
Credit Agreement.

         8. The Subordinated Creditor shall immediately affix a legend to the
instruments evidencing the Subordinated Debt stating that the instruments are
subject to the terms of this Agreement. No amendment of the documents evidencing
or relating to the Subordinated Debt shall directly or indirectly modify the
provisions of this Agreement in any manner which might terminate or impair the
subordination of the Subordinated Debt or the subordination of the security
interest or lien that the Subordinated Creditor may have in any property of the
Borrower. By way of example, such instruments shall not be amended to (i)
increase the rate of interest with respect to the Subordinated Debt, or (ii)
accelerate the payment of the principal or interest or any other portion of the
Subordinated Debt.

         9. This Agreement shall remain effective for so long as the Borrower
owes any amounts to the Lender under the Credit Agreement or otherwise. If, at
any time after payment in full of the Senior Debt any payments of the Senior
Debt must be disgorged by the Lender for any reason (including, without
limitation, the bankruptcy of the Borrower), this Agreement and the relative
rights and priorities set forth herein shall be reinstated as to all such
disgorged payments as though such payments had not been made and the
Subordinated Creditor shall immediately pay over to the Lender all payments
received with respect to the Subordinated Debt to the extent that such payments
would have been prohibited hereunder. At any time and from time to time, without
notice to the Subordinated Creditor, the Lender may take such actions with
respect to the Senior Debt as the Lender, in its sole discretion, may deem
appropriate, including, without limitation, terminating advances to the
Borrower, increasing the principal amount, extending the time of payment,
increasing applicable interest rates, renewing, compromising or otherwise
amending the terms of any documents affecting the Senior Debt and any collateral
securing the Senior Debt, and enforcing or failing to enforce any rights against
the Borrower or any other person. No such action or inaction shall impair or
otherwise affect the Lender's rights hereunder. The Subordinated Creditor waives
the benefits, if any, of Civil Code Sections 2809, 2810, 2819,



                                        3

<PAGE>   138

2845, 2847, 2848, 2849, 2850, 2899 and 3433.

         10. This Agreement shall bind any successors or assignees of the
Subordinated Creditor and shall benefit any successors or assigns of the Lender.
This Agreement is solely for the benefit of the Subordinated Creditor and the
Lender and not for the benefit of the Borrower or any other party.

         11. This Agreement may be executed in two or more counterparts, each of
which shall be deemed an original and all of which together shall constitute one
instrument.

         12. This Agreement shall be governed by and construed in accordance
with the laws of the State of California, without giving effect to conflicts of
laws principles. The Subordinated Creditor and the Lender submit to the
exclusive jurisdiction of the state and federal courts located in Santa Clara
County, California. THE SUBORDINATED CREDITOR AND THE LENDER WAIVE THEIR 
RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR
ARISING OUT OF THIS AGREEMENT OR ANY OF THE TRANSACTIONS CONTEMPLATED HEREIN.

         13. This Agreement represents the entire agreement with respect to the
subject matter hereof, and supersedes all prior negotiations, agreements and
commitments. The Subordinated Creditor is not relying on any representations by
the Lender or the Borrower in entering into this Agreement, and the Subordinated
Creditor has kept and will continue to keep itself fully apprised of the
financial and other condition of the Borrower. This Agreement may be amended
only by written instrument signed by the Subordinated Creditor and the Lender.

         14. In the event of any legal action to enforce the rights of a party
under this Agreement, the party prevailing in such action shall be entitled, in
addition to such other relief as may be granted, all reasonable costs and
expenses, including reasonable attorneys' fees, incurred in such action.

         15. In the event that any of the terms of this Agreement conflict with
or are inconsistent with any of the terms of the Fruth Note, the terms of this
Agreement shall control.

         IN WITNESS WHEREOF, the undersigned have executed this Agreement as of
the date first above written.

                             INTERCREDITOR AGREEMENT

         This Intercreditor Agreement (the "Agreement") is made as of October
30, 1996 by and between COMERICA BANK-CALIFORNIA, a California chartered bank,
as Lender ("Comerica") and BANCO BILBAO VIZCAYA PUERTO RICO, a commercial
banking institution organized and created pursuant to the laws of the
Commonwealth of Puerto Rico ("Bilbao").


                                    RECITALS

         A. O.S.I. Puerto Rico Corporation ("OSI-PR") has borrowed or may borrow
funds in the principal amount of up to $5,800,000 (the "Loan") from Bilbao
pursuant to a Loan Agreement by and between OSI-PR and Bilbao dated November 17,
1995 (as amended from time to time, the "Bilbao Credit Agreement"). The Loan is
evidenced by a Term Note executed by OSI-PR dated November 17, 1995 in the
principal amount of $5,800,000.

         B. The Bilbao Credit Agreement is secured by a grant of a security
interest in certain assets of OSI-PR, as evidenced by certain provisions of the
Bilbao Credit Agreement and a Chattel Mortgage by and between OSI-PR and Bilbao
dated November 17, 1995 and certain other documents, agreements and instruments
evidencing, perfecting or otherwise pertaining to such security interests.

         C. Payment of certain amounts under the Bilbao Credit Agreement are
guaranteed by O.S.I. Corporation d/b/a Ocular Sciences/American Hydron ("OSI")
pursuant to a Guaranty by and between OSI and Bilbao dated as of November 17,
1995 (the "Guaranty").

         D. OSI and Comerica desire to enter into a Credit Agreement (as amended
from time to time, the "Comerica Credit Agreement") pursuant to which OSI
desires to borrow certain funds from Comerica. OSI and Comerica also desire that
payment of outstanding amounts under the Comerica Credit Agreement shall be
guaranteed by OSI-PR pursuant to a Subsidiary Guaranty by and between OSI-PR and
Comerica (the "OSI-PR Guaranty").

         E. It is a condition to entering into the Comerica Credit Agreement
that Comerica and Bilbao enter into this Agreement providing that Bilbao will
provide notice to Comerica prior to enforcing the Guaranty.

         NOW, THEREFORE, in consideration of the foregoing and in order to
induce Comerica to extend credit under the Comerica Credit Agreement, the
parties agree as follows:

                                    AGREEMENT

         1. Notice Before Enforcement of Guaranty. In the event of a default
under the Bilbao Credit Agreement or any other loan document between Bilbao and
OSI-PR, Bilbao




                                        1

<PAGE>   141

shall provide ten (10) business days prior written notice to Comerica before
taking any action to enforce the Guaranty.

         2. Notices of Default. Bilbao and Comerica agree to use their best
efforts to give to the other copies of any written notice of the occurrence or
existence of an event of default sent to OSI-PR or OSI, simultaneously with the
sending of such notice to OSI-PR or OSI but the failure to do so shall not
affect the validity of such notice or create a cause of action against or
liability on the part of the party failing to give such notice, nor shall it
create any claim or right on behalf of the other party, OSI-PR, OSI or any third
party. The sending of such notice shall not give the recipient the obligation to

                                     ANNEX A

                                     FORM OF
                               SUBSIDIARY GUARANTY


         This SUBSIDIARY GUARANTY, dated as of October 30, 1996, is made by each
entity that is identified on the signature pages hereof or that hereafter
executes and delivers a Subsidiary Joinder in substantially the form set forth
as Annex 1 hereto (each such entity, a "Guarantor") in favor of Comerica
Bank-California (the "Lender").

                                    RECITALS

                  A. The Lender has entered into that certain Credit Agreement,
dated as of October 30, 1996 (as amended, supplemented or otherwise modified
from time to time, the "Credit Agreement"), by and between O.S.I. Corporation
(the "Borrower") and Lender.

                  B. Each Guarantor is a direct or indirect subsidiary of the
Borrower and expects to derive substantial direct and indirect benefit from the
transactions contemplated by the Credit Agreement.

                  C. It is a condition precedent to the extension of credit
under the Credit Agreement that each Guarantor shall have guaranteed payment of
each and all the Obligations (as that term is defined in the Credit Agreement)
and all other debts, liabilities and obligations of the Borrower and each other
Subsidiary of the Borrower under the Loan Documents, on the terms set forth
herein.

                  D. The Borrower has agreed, in the Credit Agreement, to cause
all future Material Subsidiaries of the Borrower to become party to this
Guaranty, as a Guarantor hereunder.

                  NOW, THEREFORE, in consideration of the foregoing and in order
to induce the Lender to extend credit to the Borrower under the Credit
Agreement, each Guarantor hereby agrees as follows:

                                    ARTICLE I
                        DEFINITIONS AND ACCOUNTING TERMS

                  SECTION 1.1 General Definitions. Except as otherwise
specifically provided herein, the terms that are defined in Section 1.1 of the
Credit Agreement shall have the same meanings when used in this Guaranty and the
provisions of Sections 1.2 and 1.3 of the Credit Agreement shall apply to this
Guaranty.

                  SECTION 1.2 Certain Defined Terms. As used in this Guaranty,
the following




                                        5

<PAGE>   145

terms shall have the following meanings:

                  "Bankruptcy Code" means Title 11 of the United States Code, as
from time to time amended.

                  "Guaranteed Obligations" is defined in Section 2.1(a).

                  "Guaranty" means this Subsidiary Guaranty, dated as of October
30, 1996, made by the Guarantors for the benefit of the Lender.

                  "Guaranty Taxes" is defined in Section 3.8(a).

                  "Subordinated Liabilities" is defined in Section 2.8(a).

                  "Subsidiary Joinder" means an instrument substantially in the
form of Annex 1 hereto.

                                   ARTICLE II
                         GUARANTY AND RELATED PROVISIONS

                  SECTION II.1 Guaranty.  Each Guarantor hereby unconditionally:

                  (a) guarantees the punctual payment when due, whether at
         stated maturity, by acceleration or otherwise, of (i) all Obligations
         now outstanding or hereafter arising under or in connection with the
         Credit Agreement or any other Loan Document, whether for principal,
         interest, fees, taxes, additional compensation, expense reimbursements,
         indemnification or otherwise, and (ii) all liabilities of each
         Guarantor now outstanding or hereafter arising under the Guaranty and
         any Subsidiary Joinder, and (iii) each other debt, liability or
         obligation of the Borrower or any Subsidiary of the Borrower now
         outstanding or hereafter arising under any of the Loan Documents (such
         Obligations, liabilities and other debts, liabilities and obligations,
         collectively, are the "Guaranteed Obligations"), and

                  (b) agrees to pay on demand (i) all Disallowed
         Post-Commencement Interest and Expenses, to the Person entitled to
         payment thereof if the claim therefor had been allowed in any
         Bankruptcy, Insolvency or Liquidation Proceeding, and (ii) all costs
         and expenses (including, without limitation, reasonable attorneys' fees
         and legal expenses) incurred by the Lender in enforcing this Guaranty.

                  SECTION II.2 Acceleration of Payment. If (i) the Advances
become immediately due and payable pursuant to Section 6.1 of the Credit
Agreement, (ii) any Bankruptcy, Insolvency or Liquidation Proceeding is
commenced voluntarily by any Guarantor, or (iii) any Bankruptcy, Insolvency or
Liquidation Proceeding is commenced involuntarily against any Guarantor and
either (x) remains pending for more than 30 days or (y) an order for



                                        6

<PAGE>   146

relief is granted or consented to by the Borrower or by the debtor therein, then
all liability of each Guarantor under this Guaranty in respect of any Guaranteed
Obligation that is not then due and payable shall thereupon become and be
immediately due and payable, without notice or demand.

                  SECTION II.3 Guaranty Absolute and Unconditional. Each
Guarantor guarantees that the Guaranteed Obligations will be paid in accordance
with the terms of the Credit Agreement and the other Loan Documents, regardless
of any law, regulation or order now or hereafter in effect in any jurisdiction
affecting any of such terms or the rights and claims of the Lender against the
Borrower or any Subsidiary of the Borrower with respect thereto and even if any
such rights or claims are modified, reduced or discharged in a Bankruptcy,
Insolvency or Liquidation Proceeding or otherwise. The obligations of each
Guarantor under this Guaranty are independent of the Guaranteed Obligations, and
a separate action or actions may be brought and prosecuted against each
Guarantor to enforce this Guaranty, whether or not any action is brought against
the Borrower or any other Guarantor and whether or not the Borrower or any other
Guarantor is joined in any such action or actions. The liability of each
Guarantor under this Guaranty shall be absolute and unconditional irrespective
of: (i) any lack of validity or enforceability of the Credit Agreement or any
other Loan Document or any other agreement or instrument relating thereto; (ii)
any change in the time, manner or place of payment of, or in any other term of,
any of the Guaranteed Obligations, or any other amendment or waiver of or any
consent to departure from the Credit Agreement or any other Loan Document,
including, without limitation, any increase in the Guaranteed Obligations
resulting from the extension of additional credit to the Borrower or any of its
Subsidiaries or otherwise; (iii) any taking, exchange, release or non-perfection
of any Lien securing, or any taking, release or amendment or waiver of or
consent to departure from any other guaranty of, any of the Guaranteed
Obligations; (iv) any manner or order of sale or other enforcement of any Lien
securing any or all of the Guaranteed Obligations or any manner or order of
application of the proceeds of any such Lien to the payment of the Guaranteed
Obligations or any failure to enforce any Lien or to apply any proceeds thereof;
(v) any change, restructuring or termination of the corporate structure or
existence of the Borrower or any of its Subsidiaries; or (vi) any other
circumstance which might otherwise constitute a defense (except the defense of
payment) available to, or a discharge of, a surety or guarantor.

                  SECTION II.4 Guaranty Irrevocable and Continuing. This
Guaranty is an irrevocable and continuing offer and agreement guaranteeing
payment of any and all Guaranteed Obligations and shall extend to all Guaranteed
Obligations now outstanding or created or incurred at any future time, whether
or not created or incurred pursuant to any agreement presently in effect or
hereafter made, until all obligations of the Lender to extend credit to the
Borrower have expired or been terminated and all Guaranteed Obligations have
been fully, finally and indefeasibly paid. To the extent any contingent
Obligation survives the expiration or termination of the Credit Agreement and
the repayment of the Advances, each Guarantor's liability under this Guaranty
shall likewise survive. This Guaranty may be released only in writing except,
with respect to a given Guarantor, as provided for in Section 2.10.

<PAGE>   147

                  SECTION 2.5 Reinstatement. If at any time any payment on any
Guaranteed Obligation is set aside, avoided or rescinded or must otherwise be
restored or returned, this Guaranty and the liability of each Guarantor under
this Guaranty shall remain in full force and effect and, if previously released
or terminated, shall be automatically and fully reinstated, without any
necessity for any act, consent or agreement of any Guarantor, as fully as if
such payment had never been made and as fully as if any such release or
termination had never become effective.

                  SECTION 2.6 Waiver. Guarantor hereby waives and relinquishes
all rights, remedies and defenses accorded by applicable law to sureties or
guarantors and agrees not to assert or take advantage of any such rights,
remedies or defenses, including without limitation:

                  (a) any right to require the Lender to proceed against
         Borrower or any other Person or to proceed against or exhaust any
         security held by the Lender at any time or to pursue any other remedy
         in the power of the Lender before proceeding against Guarantor;

                  (b) the defense of the statute of limitations in any action
         hereunder or in any action for the collection or performance of any
         Guaranteed Obligations;

                  (c) any defense that may arise by reason of the incapacity,
         lack of authority, death or disability of any other Person or the
         failure of the Lender to file or enforce a claim against the estate (in
         administration, bankruptcy or any other proceeding) of any other
         Person;

                  (d) demand, presentment, protest and notice of any kind,
         including without limitation notice of the existence, creation or
         incurring of any new or additional indebtedness or obligation or of any
         action or non-action on the part of Borrower, Lender, any endorser or
         creditor of Borrower or Guarantor or on the part of any other Person
         under this or any other instrument in connection with any obligation or
         evidence of indebtedness held by Lender as Collateral or in connection
         with any Guaranteed Obligations;

                  (e) any defense based upon an election of remedies by the
         Lender (including without limitation an election to proceed by
         non-judicial rather than judicial foreclosure) irrespective of whether
         such election destroys or otherwise impairs any subrogation rights of
         Guarantor, the right of Guarantor to proceed against Borrower for
         reimbursement, or both (it being understood that as a consequence of
         the waiver set forth in this Section 2.6(e), Guarantor is waiving,
         among other things, any defense that Guarantor might be able to invoke
         under California law based upon the argument (as enunciated in, among
         other cases, Union Bank v. Gradsky, 265 Cal. App. 2d 40 (1968), and
         Cathay Bank v. Lee, 93 Los Angeles Daily Journal D.A.R. 4871 (1993)),
         that an election by a lender to foreclose non-judicially under a deed
         of trust effects a release of the Guarantor from any obligation to pay,
         under its guaranty, any portion of the guaranteed obligation remaining
         unpaid after the non-judicial foreclosure since the non-judicial
         foreclosure could destroy




                                        8

<PAGE>   148

         or impair Guarantor's subrogation or other rights to obtain any
         reimbursement from the Borrower for such payments);

                  (f) any defense based upon any statute or rule of law which
         provides that the obligation of a surety must be neither larger in
         amount nor in other respects more burdensome than that of the
         principal;

                  (g) any duty on the part of the Lender to disclose to
         Guarantor any facts the Lender may now or hereafter know about
         Borrower, regardless of whether the Lender has reason to believe that
         any such facts materially increase the risk beyond that which Guarantor
         intends to assume, or has reason to believe that such facts are unknown
         to Guarantor, or has a reasonable opportunity to communicate such facts
         to Guarantor, since Guarantor acknowledges that Guarantor is fully
         responsible for being and keeping informed of the financial condition
         of Borrower and of all circumstances bearing on the risk of non-payment
         of any Guaranteed Obligations;

                  (h) any defense arising because of the election by the Lender,
         in any proceeding instituted under the Bankruptcy Code, of the
         application of Section 1111(b)(2) of the Bankruptcy Code; and

                  (i) any defense based upon any borrowing or grant of a
         security interest under Section 364 of the Federal Bankruptcy Code.

                  Without limiting the generality of the foregoing, Guarantor
hereby expressly waives any and all benefits which might otherwise be available
to Guarantor under California Civil Code Sections 2809, 2810, 2819, 2839, 2845
through 2850, 2899 and 3433, California Code of Civil Procedure Sections 580(a),
580(b), 580(d) and 726, and California Commercial Code Section 3606(1).

                  SECTION II.7 Subrogation. Each Guarantor hereby represents,
warrants and agrees, in respect of any and all present and future rights of
subrogation, recourse, reimbursement, indemnity, exoneration, contribution and
other claims that such Guarantor at any time may have against the Borrower, any
other Guarantor or any other Person liable for the payment of any of the
Guaranteed Obligations (including, without limitation, the owner of any interest
in collateral subject to a Lien securing any of the Guaranteed Obligations) as a
result of or in connection with this Guaranty or any payment hereunder, that:

                  (a) No Agreement. Such Guarantor has not entered into, and
         agrees that it will not enter into, any agreement providing, directly
         or indirectly, for any such right or claim against the Borrower or,
         except as set forth in Section 2.10, against any other Subsidiary of
         the Borrower, and each such agreement now existing or hereafter entered
         into (except as provided for in Section 2.10) is and shall be void;

                  (b) Release.  Such Guarantor waives and releases any such
         right or claim




                                        9

<PAGE>   149

         against the Borrower, any other Guarantor or any other such Person
         until the Guaranteed Obligations have been paid in full;

                  (c) Capital Contribution. Neither the execution and delivery
         of this Guaranty by such Guarantor nor any payment by such Guarantor
         under this Guaranty shall give rise to any claim (as that term is
         defined in the Bankruptcy Code) in favor of such Guarantor against the
         Borrower until the Guaranteed Obligations have been paid in full; and

                  (d) Subordination of Contribution Rights. Such Guarantor
         reserves, as against each other Guarantor, its right of contribution
         under Section 2.10 but agrees that all such contribution rights shall
         be included among the Subordinated Liabilities.

                  SECTION II.8 Subordination Provisions.

                  (a) Subordination. Any and all present and future debts,
         liabilities and obligations of every type and description (whether for
         money borrowed, on intercompany accounts, for provision of goods or
         services, under tax sharing or contribution agreements or on account of
         any other transaction, agreement, occurrence or event and whether
         absolute or contingent, direct or indirect, matured or unmatured,
         liquidated or unliquidated, created directly or acquired from another,
         or sole, joint, several or joint and several) of the Borrower or any
         Subsidiary of the Borrower now outstanding or hereafter incurred or
         owed to any Guarantor (the "Subordinated Liabilities") shall be, and
         hereby are, subordinated to full and final payment of the Guaranteed
         Obligations.

                  (b) Prohibited Payments. If any Event of Default or Potential
         Default occurs, then for so long as such Event of Default or Potential
         Default may be continuing, no Guarantor will demand, sue for, accept or
         receive, or cause or permit any other Person to make, any payment on or
         transfer of property on account of any Subordinated Liabilities.

                  (c) No Liens or Transfers. Each Guarantor agrees that (i) it
         will not demand, accept or hold any Lien upon any real or personal
         property of the Borrower or any of its Subsidiaries as security for any
         of the Subordinated Liabilities and (ii) any such Lien shall be void.

                  (d) Insolvency Proceedings. In any Bankruptcy, Insolvency or
         Liquidation Proceeding, the Lender shall be entitled to receive payment
         in full of all amounts due or to become due on or in respect of the
         Guaranteed Obligations, or provision shall be made for such payment in
         money or money's worth, before any Guarantor is entitled to receive any
         payment or distribution of any kind or character, whether in cash,
         property or securities, on account of any of the Subordinated
         Liabilities, and to that end the Lender shall be entitled to receive,
         for application to the payment thereof, all payments and distributions
         of any kind or character, whether in cash, property or securities
         (including any such payment or distribution which may be payable or
         deliverable by reason of the payment of any other debt or liability of
         the Borrower or any Subsidiary of the Borrower




                                       10

<PAGE>   150

         being subordinated to the payment of the Subordinated Liabilities),
         which may be payable or deliverable in respect of the Subordinated
         Liabilities in any such Bankruptcy, Insolvency or Liquidation
         Proceeding.

                  (e) Disallowed Post-Commencement Interest and Expenses.  If in
         any Bankruptcy, Insolvency or Liquidation Proceeding (i) any payment or
         distribution of any kind or character, whether in cash, property or
         securities (including any such payment or distribution which may be
         payable or deliverable by reason of the payment of any other debt or
         liability of the Borrower or any Subsidiary of the Borrower being
         subordinated to the payment of the Subordinated Liabilities) is payable
         or deliverable in respect of the Subordinated Liabilities, and (ii) the
         Lender is not otherwise entitled to receive such payment or
         distribution pursuant to Section 2.8(d), and (iii) any amount remains
         unpaid to the Lender on account of any Disallowed Post- Commencement
         Interest and Expenses, then the Lender shall be entitled to receive
         payment of all such unpaid Disallowed Post-Commencement Interest and
         Expenses from and out of any and all such payments and distributions in
         respect of the Subordinated Liabilities.

                  (f) Held in Trust. If any payment, transfer or distribution is
         made to any Guarantor upon any Subordinated Liabilities that is not
         permitted to be made under this Section 2.8 or that the Lender is
         entitled to receive under this Section 2.8, such Guarantor shall
         receive and hold the same in trust, as trustee for the benefit of the
         Lender, and shall forthwith transfer and deliver the same to the
         Lender, in precisely the form received (except for any required
         endorsement), for application to the payment of Guaranteed Obligations
         or any unpaid Disallowed Post-Commencement Interest and Expenses.

                  (g) Claims in Bankruptcy. Each Guarantor will file all claims
         against the Borrower or any Subsidiary of the Borrower in any
         Bankruptcy, Insolvency or Liquidation Proceeding in which the filing of
         claims is required or permitted by law upon any of the Subordinated
         Liabilities and will assign to the Lender, all rights of such Guarantor
         thereunder. If any Guarantor does not file any such claim at least 30
         days prior to any applicable claims bar date, the Lender is hereby
         authorized (but shall not be obligated), as attorney-in-fact for such
         Guarantor with full power of substitution, either to file such claim or
         proof thereof in the name of such Guarantor or, at the option of the
         Lender, to assign the claim and cause the claim or proof thereof to be
         filed by an agent or nominee. The Lender and its agents and nominees
         shall have the sole right, but no obligation, to accept or reject any
         plan proposed in such Bankruptcy, Insolvency or Liquidation Proceeding
         and to cast any votes and to take any other action with respect to all
         claims upon any of the Subordinated Liabilities.

                  (h) Subordination Effective and not Impaired. This Section 2.8
         shall remain effective for so long as this Guaranty is continuing and
         thereafter for so long as any Guaranteed Obligation is outstanding.
         Each Guarantor's obligations under this Section 2.8: (i) shall be
         absolute and unconditional as set forth in Section 2.3, irrevocable and
         continuing as set forth in Section 2.4, subject to reinstatement as set
         forth in Section 2.5




                                       11

<PAGE>   151

         and not be affected or impaired by any of the matters waived in Section
         2.6; (ii) shall be subject to the provisions of Article III; and (iii)
         shall otherwise be as equally enduring and free from defenses as such
         Guarantor's liability under this Guaranty.

                  SECTION II.9 Fraudulent Transfer Limitation. If, in any action
to enforce this Guaranty or any proceeding to allow or adjudicate a claim under
this Guaranty, a court of competent jurisdiction determines that enforcement of
this Guaranty against any Guarantor for the full amount of the Guaranteed
Obligations is not lawful under, or would be subject to avoidance under, Section
548 of the Bankruptcy Code or any applicable provision of comparable state law,
the liability of such Guarantor under this Guaranty shall be limited to the
maximum amount lawful and not subject to avoidance under such law.

                  SECTION II.10 Contribution among Guarantors. The Guarantors
desire to allocate among themselves, in a fair and equitable manner, their
rights of contribution from each other when any payment is made by one of the
Guarantors under this Guaranty. Accordingly, if any payment is made by a
Guarantor under this Guaranty (a "Funding Guarantor") that exceeds its Fair
Share, the Funding Guarantor shall be entitled to a contribution from each other
Guarantor in the amount of such other Guarantor's Fair Share Shortfall, so that
all such contributions shall cause each Guarantor's Aggregate Payments to equal
its Fair Share. For these purposes:

                  (a) "Fair Share" means, with respect to a Guarantor as of any
         date of determination, an amount equal to (i) the ratio of (x) the
         Adjusted Maximum Amount of such Guarantor to (y) the aggregate Adjusted
         Maximum Amounts of all Guarantors, multiplied by (ii) the aggregate
         amount paid on or before such date by all Funding Guarantors under this
         Guaranty.

                  (b) "Fair Share Shortfall" means, with respect to a Guarantor
         as of any date of determination, the excess, if any, of the Fair Share
         of such Guarantor over the Aggregate Payments of such Guarantor.

                  (c) "Adjusted Maximum Amount" means, with respect to a
         Guarantor as of any date of determination, the maximum aggregate amount
         of the liability of such Guarantor under this Guaranty, limited to the
         extent required under Section 2.9 (except that, for purposes solely of
         this calculation, any assets or liabilities arising by virtue of any
         rights to or obligations of contribution under this Section 2.10 shall
         not be counted as assets or liabilities of such Guarantor).

                  (d) "Aggregate Payments" means, with respect to a Guarantor as
         of any date of determination, the aggregate net amount of all payments
         made on or before such date by such Guarantor under this Guaranty
         (including, without limitation, under this Section 2.10).

The amounts payable as contributions hereunder shall be determined by the
Funding Guarantor




                                       12

<PAGE>   152

as of the date on which the related payment or distribution is made by the
Funding Guarantor, and such determination shall be binding on the other
Guarantors absent manifest error. The allocation and right of contribution among
the Guarantors set forth in this Section 2.10 shall not be construed to limit in
any way the liability of any Guarantor under this Guaranty to the Lender.

                  SECTION II.11 Joint and Several Obligation. This Guaranty and
all liabilities of each Guarantor hereunder shall be the joint and several
obligation of each Guarantor and may be freely enforced against each Guarantor,
for the full amount of the Guaranteed Obligations (subject to Section 2.9),
without regard to whether enforcement is sought or available against any other
Guarantor.

                                   ARTICLE III
                            MISCELLANEOUS PROVISIONS

                  SECTION III.1 Condition of the Borrower. Each Guarantor is
fully aware of the financial condition of the Borrower and its Subsidiaries and
is executing and delivering this Guaranty based solely upon such Guarantor's own
independent investigation of all matters pertinent hereto and is not relying in
any manner upon any representation or statement by the Lender. Each Guarantor
represents and warrants that it is in a position to obtain, and each Guarantor
hereby assumes full responsibility for obtaining, any additional information
concerning the financial condition of the Borrower and each of its Subsidiaries
and any other matter pertinent hereto as such Guarantor may desire, and such
Guarantor is not relying upon or expecting the Lender to furnish to such
Guarantor any information now or hereafter in the possession of the Lender
concerning the same or any other matter. By executing this Guaranty, each
Guarantor knowingly accepts the full range of risks encompassed within a
contract of this type, which risks each Guarantor acknowledges. No Guarantor
shall have the right to require the Lender to obtain or disclose any information
with respect to the Guaranteed Obligations, the financial condition or prospects
of the Borrower or any Subsidiary of the Borrower, the ability of the Borrower
or any Subsidiary of the Borrower to pay or perform the Guaranteed Obligations,
the existence, perfection, priority or enforceability of any collateral security
for any or all of the Guaranteed Obligations, the existence or enforceability of
any other guaranties of all or any part of the Guaranteed Obligations, any
action or non-action on the part of the Lender, the Borrower, any Subsidiary of
the Borrower or any other Person, or any other event, occurrence, condition or
circumstance whatsoever.

                  SECTION III.2 Amendments.

                  (a) Amendment to Guaranty. No amendment or waiver of any
         provision of this Guaranty, no consent to any departure by any
         Guarantor herefrom, shall in any event be effective unless the same
         shall be in writing and signed by the Lender, and then such waiver or
         consent shall be effective only in the specific instance and for the
         specific purpose for which given, except that no amendment, waiver or
         consent shall, unless in writing and signed by the Lender, (i) reduce
         or discharge the liability of any Guarantor



                                       13

<PAGE>   153

         hereunder, or (ii) postpone any date fixed for payment hereunder.

                  (b) Amendment or Modification of Other Loan Documents. The
         other Loan Documents may be amended, modified or supplemented in
         accordance with their terms without notice to or consent or agreement
         by any Guarantor, including, without limitation, so as to (i) alter,
         compromise, modify, accelerate, extend, renew, refinance or change the
         time or manner for making of Advances, provision of other financial
         accommodations, or the payment or performance of all or any portion of
         the Guaranteed Obligations, (ii) increase or reduce the rate of
         interest or amount of principal payable on the Guaranteed Obligations,
         (iii) release or discharge the Borrower, any other Loan Party or any
         other Person as to all or any portion of the Guaranteed Obligations, or
         (iv) release, substitute or add any one or more guarantors or
         endorsers, accept additional or substituted security for payment or
         performance of the Guaranteed Obligations, or release or subordinate
         any security therefor.

                  SECTION III.3 Notices. All notices and other communications
provided for hereunder shall be in writing (including telecopier, telegraphic,
telex or cable communication) and mailed, telecopied, telegraphed, telexed,
cabled or delivered, if to any Guarantor, c/o O.S.I. Corporation, 475 Eccles
Avenue, South San Francisco, California 94080, Attention: Treasurer, with a copy
to the General Counsel at the same address, and if to the Lender, at its address
specified in the Credit Agreement, or, as to any party, at such other address as
shall be designated by such party in a written notice to each other party. All
such notices and other communications shall, when mailed, telecopied,
telegraphed, telexed or cabled, be effective when deposited in the mails,
telecopied, delivered to the telegraph company, confirmed by telex answerback or
delivered to the cable company, respectively.

                  SECTION III.4 Right of Set off. If any Advances become
immediately due and payable pursuant to Section 6.1 of the Credit Agreement, the
Lender shall have the right at any time, and from time to time thereafter, to
the fullest extent permitted by law, to set off and apply any and all deposits
(general or special, time or demand, provisional or final) at any time held and
other liability at any time owing by Lender to or for the credit or the account
of any Guarantor against any and all liability of such Guarantor under this
Guaranty, whether or not Lender shall have made any demand under this Guaranty
and even though such deposit or liability may then be unmatured. Lender agrees
to promptly notify the affected Guarantor after any such set-off and application
made by Lender, but the failure to give such notice shall not affect the
validity of such set-off and application. The rights of the Lender under this
Section 3.4 are in addition to other rights and remedies (including, without
limitation, other rights of set-off) which Lender may have.

                  SECTION III.5 Successors and Assigns. This Guaranty is binding
upon and enforceable against each Guarantor, its successors and assigns, and
shall inure to the benefit of, and be enforceable by, the Lender and its
representatives, successors and assigns.



                                       14

<PAGE>   154


                  SECTION III.6 No Inquiry. The Lender may rely, without further
inquiry, on the power and authority of each Guarantor, the Borrower and each of
its Subsidiaries and on the authority of all officers, directors and agents
acting or purporting to act on their behalf.

                  SECTION III.7 Involuntary Proceedings. So long as the Lender
is obligated to extend credit under the Credit Agreement or any Guaranteed
Obligations are outstanding, no Guarantor will, without the prior written
consent of the Lender, commence or join with any other Person in commencing any
Bankruptcy, Insolvency or Liquidation Proceeding against the Borrower or any of
its Subsidiaries.

                  SECTION III.8 Payments Free and Clear of Taxes.

                  (a) Payment. Each Guarantor agrees to pay any and all present
         or future taxes, levies, imposts, deductions, charges or withholdings,
         and all liabilities with respect thereto which arise from any payment
         made hereunder or from the execution, delivery or registration of, or
         otherwise with respect to, this Guaranty, excluding, with respect to
         the Lender, taxes imposed on its net income (collectively, the
         "Guaranty Taxes").

                  (b) Indemnity. Each Guarantor hereby indemnifies the Lender
         for the full amount of Guaranty Taxes (including, without limitation,
         any Guaranty Taxes imposed by any jurisdiction on amounts payable under
         this Section 3.8) paid by the Lender and any liability (including
         penalties, interest and expenses) arising therefrom or with respect
         thereto (plus interest on any amounts not paid within thirty days from
         the date written demand is made therefor at a rate equal to the rate
         payable under the Credit Agreement on Base Rate Advances during the
         continuance of a default in the repayment of Advances), whether or not
         such Guaranty Taxes were correctly or legally asserted; provided,
         however, that if the Lender subsequently recoups all or any part of
         such amount from the relevant taxation authority or other authority,
         then the Lender shall identify and remit the amount of the recoupment
         to such Guarantor within five Business Days after it receives the
         recoupment.

                  (c) Survival. Without prejudice to the survival of any other
         agreement of any Guarantor hereunder, the agreements and obligations of
         each Guarantor contained in this Section 3.8 shall survive the full and
         final payment and performance of the Guaranteed Obligations.

                  (d) Receipt. Within 30 days after the date of any payment of
         Guaranty Taxes by any Guarantor, such Guarantor shall furnish to the
         Lender a receipt for any Guaranty Taxes paid by such Guarantor pursuant
         to this Section 3.8.

                  SECTION III.9 No Waiver; Remedies. No failure on the part of
the Lender to exercise, and no delay in exercising, any right hereunder shall
operate as a waiver thereof, and no single or partial exercise of any right
hereunder shall preclude any other or further exercise of



                                       15

<PAGE>   155


any other right or of the same right as to any other matter or on a subsequent
occasion.

                  SECTION III.10 Remedies Cumulative. All rights, powers and
remedies of the Lender under this Guaranty, under any other agreement now or at
any time hereafter in effect between the Lender and any Guarantor (whether
relating to the Guaranteed Obligations or otherwise) or now or hereafter
existing at law or in equity or by statute or otherwise, shall be cumulative and
concurrent and not alternative and each such right, power and remedy may be
exercised independently of, and in addition to, each other such right, power or
remedy.

                  SECTION III.11 Severally Enforceable. This Guaranty may be
enforced severally and successively by the Lender in one or more actions,
whether independent, concurrent, joint, successive or otherwise.

                  SECTION III.12 Counterparts. This Guaranty may be executed in
counterparts, and each such counterpart for all purposes shall be deemed an
original and all such counterparts together shall constitute but one and the
same agreement.

                  SECTION III.13 Severability. If any provision hereof or the
application thereof in any particular circumstance is held to be unlawful or
unenforceable in any respect, all other provisions hereof and such provision in
all other applications shall nevertheless remain effective and enforceable to
the maximum extent lawful.

                  SECTION III.14 Integration. This Guaranty and the other Loan
Documents to which any Guarantor is party are intended as an integrated and
final expression of the entire agreement of such Guarantor with respect to the
subject matter hereof and thereof. No representation, understanding, promise or
condition concerning the subject matter hereof and thereof shall be binding upon
the Lender unless expressed herein or therein, and no course of prior dealing or
usage of trade, and no parol or extrinsic evidence of any nature, shall be
admissible to supplement, modify or vary any of the terms hereof or thereof.
Acceptance of or acquiescence in a course of performance rendered under this
Guaranty or any other dealings between any Guarantor and the Lender shall not be
relevant to determine the meaning of this Guaranty even though the accepting or
acquiescing party had knowledge of the nature of the performance and opportunity
for objection.

                  SECTION III.15 GOVERNING LAW; SUBMISSION TO JURISDICTION;
WAIVER OF JURY TRIAL; WAIVER OF DAMAGES.

                  (a) GOVERNING LAW.  THIS GUARANTY SHALL BE GOVERNED BY, AND

         APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR
         MODIFICATIONS TO THIS GUARANTY AND THE OTHER LOAN DOCUMENTS.

                  (d) LIMITATION OF LIABILITY. NO CLAIM MAY BE MADE BY ANY

the Borrower and O.S.I. Puerto Rico that are listed on Exhibit A attached hereto
(the "MATERIAL AGREEMENTS"), which contracts, instruments, documents and
agreements the Borrower and O.S.I. Puerto Rico, respectively, have represented
to us to be the only material agreements to which they are a party or by which
their assets are bound.

         In connection with this opinion we have not examined, and we express no
opinion with respect to, any documents other than the Reviewed Documents
expressly referred to above and have not made any other independent factual
investigation. We have assumed, based solely upon the representations made to us
by the Borrower and O.S.I. Puerto Rico






                                       -2-

in the Management Certificates, that, neither the Borrower or O.S.I. Puerto Rico
nor either of their assets, is a party to, bound by or subject to any agreement
or instrument that would change any conclusion stated in this opinion.

         As to matters of fact relevant to this opinion, we have relied solely
upon our examination of the Reviewed Documents and representations and
warranties made by representatives of the Borrower and O.S.I. Puerto Rico to us,
including without limitation, those set forth in the Management Certificates,
and the representations and warranties made by the Borrower and the Lender in
the Loan Documents and by O.S.I. Puerto Rico and the Lender in the Guaranty. We
have made no independent investigation or other attempt to verify the accuracy
of any of such information, representations, warranties or other facts as
represented by the Borrower, O.S.I. Puerto Rico or the Lender or to verify the
existence or non-existence of any other factual matters. In particular, but not
by way of limitation, in rendering our opinion expressed in paragraph 6 below,
we have not caused the search of any docket of any court, tribunal, agency or
similar authority.

         In our examination, we have assumed, without independent investigation,
and express no opinion as to (a) the authenticity and completeness of all
original documents submitted to us as originals, (b) the genuineness of all
signatures on such documents, (c) the completeness and conformity to originals
of all documents submitted to us as copies, (d) the legal competence of all
natural persons who are signatories of original documents, (e) the lack of any
undisclosed modifications, waivers or amendments to any agreements or other
documents examined by us, (f) the due execution and delivery of all documents by
all parties thereto (other than the Borrower and O.S.I. Puerto Rico) where due
execution and delivery are prerequisites to the effectiveness thereof, (g) the
accuracy, completeness and authenticity of certificates of public officials. For
the purposes of this opinion, we have also assumed, without independent
investigation, that: (i) the Loan Documents and Guaranty reflect the complete
understanding and agreement of the parties concerning the subject matter
thereof, (ii) the Loan Documents have been duly authorized, executed and
delivered by the Lender and are legal, valid and binding obligations of the
Lender, enforceable against the Lender in accordance with their respective
terms; (iii) the Borrower is not insolvent and by executing and delivering the
Loan Documents will not become insolvent; (iv) O.S.I. Puerto Rico is not
insolvent and by executing and delivering the Guaranty will not become
insolvent; (v) that the Lender qualifies for an exemption from the otherwise
applicable interest rate limitations of California law for loans or forbearances
contained in Article XV, Section 1 of the California Constitution; (vi) that all
loans under the Loan Documents will be made by the Lender for its own account or
for the account of another person or entity that qualifies for an exemption from
the interest rate limitations of California law; and (vii) there is no present
agreement or plan, express or implied, on the part of the Lender to sell
participations or any other interest in the loans to be made under the Loan
Documents to any person or entity other than a person or entity that also
qualifies for an exemption from the interest rate limitations of California law.

         A matter stated below to be "to our knowledge" or "known to us" refers
only to the actual knowledge of those attorneys currently in this firm who have
rendered legal services to the Borrower in connection with the Loan Documents,
and means that, while such attorneys have not been informed by the Borrower that
the matter stated is factually incorrect, we have made no independent factual
investigation with respect to such matter. No inference as to our knowledge of
any matters bearing on the accuracy of any such statement should be drawn from
the fact of our representation of the Borrower.

         With respect to our opinion in paragraph 4 below, we have relied
solely upon copies, supplied to us by Borrower, of those contracts, instruments,
documents and agreements which have been identified to us by Borrower and O.S.I.
Puerto Rico in the Management Certificates as being all material contracts,
instruments, documents and agreements to which the Borrower or O.S.I. Puerto
Rico is a party or by which its assets are bound. Each of the foregoing are
listed as Material Agreements on Exhibit A hereto. We have not undertaken any
independent investigation of such matters.

         We do not assume any responsibility for the accuracy, completeness or
fairness of any information, including, but not limited to, financial
information, furnished to you by the Borrower or O.S.I. Puerto Rico concerning
the business, assets or affairs of the Borrower or O.S.I. Puerto Rico or any
other information furnished to you by the Borrower or O.S.I. Puerto Rico or any
of their agents or representatives.

         Where statements in this opinion are qualified by the term "material,"
those statements involve judgments and opinions as to the materiality or lack of
materiality of any matter to the Borrower or its business, assets or financial
condition, which are entirely those of the Borrower and its officers.

         This opinion is subject to, and we render no opinion with respect to,
the limitations, qualifications and exceptions applicable to contracts and
obligations generally. Without limitation, this opinion is subject to, and we
render no opinion with respect to, the following:

         (a) the effect of bankruptcy, insolvency, reorganization, arrangement,
moratorium, bulk sales, fraudulent conveyance and other similar laws now or
hereinafter in effect relating to or affecting the rights and remedies of
creditors generally;

         (b) the effect of general principles of equity, including, without
limitation, concepts of materiality, reasonableness, good faith and fair dealing
and the possible unavailability of specific performance, injunctive relief or
other equitable remedies, regardless of whether considered in a proceeding in
equity or at law;

         (c) the effect of limitations imposed by reason of generally applicable
public policy principles or considerations or limitations imposed by or
resulting from the exercise by any court of its discretion;






                                       -4-

<PAGE>   165


         (d) any implied duty or covenant of good faith and fair dealing to
which the Lender may have been or may be subject;

         (e) the effect of Section 1670.5 of the California Civil Code and of
California court decisions, invoking statutes or principles of equity, which
have held that certain covenants and provisions of agreements are unenforceable
where (i) the breach of such covenants or provisions imposes restrictions or
burdens upon the other party and it cannot be demonstrated that the enforcement
of such restrictions or burdens is reasonably necessary for the protection of
the party seeking to enforce such provisions or (ii) the enforcement of such
covenants or provisions under the circumstances would violate the implied
covenant of good faith and fair dealing;

         (f) The effect of California Civil Code Section 1698 and similar
statutes and federal laws and judicial decisions that provide, among other
things, (i) that oral modifications to a contract or waivers of contractual
provisions may be enforceable, if the modification was performed,
notwithstanding any express provision in the agreement that the agreement may
only be modified or an obligation thereunder waived in writing, or (ii) that an
implied agreement may be created from trade practices or course of conduct;

         (g) The effect of California Civil Code Section 1717 and other
applicable statutes and judicial decisions which provide, among other things,
that a court may limit the granting of attorneys' fees to those attorneys' fees
which are determined by the court to be reasonable and that attorneys' fees may
be granted only to a prevailing party and that a contractual provision for
attorneys' fees is deemed to extend to both parties (notwithstanding that such
provision by its express terms benefits only one party);

         (h) The effect of any California or federal law or court decisions that
requires a lender to enforce its remedies in a commercially reasonable manner;

         (i) The enforceability of any provisions in the Loan Documents or
Guaranty releasing or exonerating a party from liability or providing for
indemnification or contribution;

         (j) The enforceability under certain circumstances of contractual
provisions respecting self-help or summary remedies;

         (k) The enforceability of any waiver of the Borrower's or O.S.I. Puerto
Rico's right to assert counterclaims or other claims or defenses;

         (l) The enforceability of any provision in the Loan Documents or
Guaranty requiring the Borrower or O.S.I. Puerto Rico to execute, in the future,
additional instruments and documents;

         (m) The enforceability of any waivers or releases of rights by the
Borrower in the Loan Documents or by O.S.I. Puerto Rico in the Guaranty, to the
extent any of such waivers or releases are not enforceable under applicable law,
including any provision in











                                       -5-



<PAGE>   166


the Loan Documents or Guaranty that purports to waive broadly or vaguely stated
rights or unknown future rights, or rights which may not be waived on statutory
or public policy grounds;

         (n) The enforceability of any provision in the Loan Documents or
Guaranty stating that rights or remedies are not exclusive, that every right or
remedy is cumulative and may be exercised in addition to, or with any other
right or remedy, or that the election of some particular remedy or remedies does
not preclude recourse to one or more others;

         (o) The enforceability of any consent to service, jurisdiction or forum
for any claim, suit, demand, action or cause of action arising under or related
to the Loan Documents or Guaranty, or the transactions contemplated therein, or
any provision providing for the exclusive jurisdiction of a particular court or
purporting to waive rights to trial by jury, service of process or objections to
the laying of venue or to forum on the basis of forum non conveniens in
connection with any litigation arising out of or pertaining to the Loan
Documents or Guaranty;

         (p) The enforceability of any provision in the Loan Documents or
Guaranty purporting to appoint the Lender as attorney-in-fact for the Borrower
or O.S.I. Puerto Rico or to grant an irrevocable power of attorney to the
Lender;

         (q) The enforceability of any provision in the Loan Documents or
Guaranty that would purport to permit or authorize the realization of, or
exercise of remedies pursuant to a security interest in personal property in any
manner inconsistent with the provisions and procedures set forth in Divisions 8
and 9 of the California Uniform Commercial Code;

         (r) The enforceability of any provision in the Loan Documents or
Guaranty that permit or authorize the Lender to exercise remedies or impose
penalties or an increase in interest rate for late payment or other default if
it is determined that the default is not material, the remedies or penalties
bear no reasonable relation to the damage suffered by the Lender as a result of
the default or it cannot be demonstrated that the enforcement of the remedies or
penalties is reasonably necessary for the protection of the Lender;

         (s) The enforceability of any provisions of the Loan Documents or
Guaranty that purport to limit the standards imposed upon the Lender for the
care of Collateral in the possession of the Lender to the extent such provisions
are inconsistent with applicable provisions of the California Uniform Commercial
Code (the "California UCC").

         (t) The enforceability of any provisions of the Loan Documents
providing for rights to registration of any securities under the Securities Act
of 1933, as amended; and

         (u) The enforceability of any provisions of the Loan Documents that

         Additionally, we express no opinion with respect to the compliance or
noncompliance with any federal or state antifraud statutes, rules and
regulations applicable to the offer or sale of securities. Furthermore, we
express no opinion with respect to the enforceability of any provision in the
Guaranty specifying the governing law, and we assume that the Guaranty will be
governed by, and construed in accordance with, California law.

         Our opinions in paragraphs 8 and 9 are also subject to the following
assumptions, exceptions, limitations and qualifications:

         (i) we express no opinion as to the priority of any security interest
or lien; 

         (ii) we express no opinion as to the creation, validity or perfection
of any security interest that is not governed by, or that is excluded from
coverage by, Division 8 and Division 9 of the California UCC;

         (iii) we have assumed that the Borrower has "rights" in the Collateral,
as contemplated by Section 9203 of the California UCC;

         (iv) we have assumed that, as of the relevant times, "value" (as that
word is used in Section 9203(l)(b) of the California UCC) has been given by the
secured party;

         (v) we express no opinion as to the accuracy or completeness of the
descriptions of the Collateral in any Loan Document or the Financing Statement;

         (vi) we have assumed that none of the Collateral consists of consumer
goods, crops growing or to be grown, timber to be cut, minerals or the like
(including oil and gas) or accounts resulting from the sale of minerals or the
like at the wellhead or the mine head, beneficial interests in a trust or
decedent's estate, letters of credit, items which are subject to a statute or
treaty of the United States which provides for a national or international
registration or a national or international certificate of title or which
specifies a place of filing different from that specified in the California UCC
for filing of the security interest, or any other items excluding from the
coverage of the California UCC by Section 9104 thereof;

         (vii) we call to your attention the fact that the perfection of a
security interest in "proceeds" (as defined in the California UCC) of collateral
is governed and restricted by Section 9306 of the California UCC;

         (viii) we express no opinion as to whether the phrase "all personal
property" or similarly general phrases would be held to describe any particular
item or items of collateral;

         (ix) we call to your attention the fact that under the California UCC,
with certain limited exceptions, the effectiveness of the Financing Statement
will lapse five years after the date of filing thereof and your security
interest will become unperfected,





                                       -7-



<PAGE>   168


unless a continuation statement is filed within six months prior to the end of
such five-year period. We also call to your attention the fact that perfection
of security interests under the California UCC in any of the Collateral will be
terminated as to any Collateral acquired by the Company more than four (4)
months after the Company changes its name, identity or corporate structure to
such an extent as to make the Financing Statement seriously misleading, unless a
new appropriate financing statement or an appropriate amendment to the Financing
Statement indicating the new name, identity or corporate structure of the
Company is properly filed before the expiration of four (4) months after such
change;

         (x) we express no opinion as to the perfection of any security interest
as against any claim or lien in favor of the United States or any State, or any
agency or instrumentality thereof, including, without limitation, liens for the
payment of federal or state taxes which are given priority by operation of law
and liens under Title IV of the Employee Retirement Income Security Act of 1974;

         (xi) we have assumed that the Lender has taken possession of the
Pledged Shares in good faith and without prior notice of any adverse claim;

         (xii) we have assumed that the Lender has not expressly or by
implication waived, subordinated or agreed to any modification of the perfection
of any security interest under the Loan Documents or agreed to any adverse
claim; and

         (xiii) we call to your attention the fact that the security interest of
the Lender in the Pledged Shares may be subject to security interests in favor
of other persons that exist pursuant to Section 8-313(1)(i) or Section 8-321 of
the California UCC if on or within 21 days prior to the date of delivery of any
Pledged Shares to the Lender, the owner of such Pledged Shares shall have signed
in favor of any person other than the Lender a security agreement which contains
a description of such Pledged Shares and shall have received new value therefor
from such person.

         We further advise you that:

         a. The enforceability of the Guaranty against O.S.I. Puerto Rico may be
subject to California statutory provisions and case law to the effect that, in
certain circumstance, a guarantor may be exonerated if the beneficiary of the
Guaranty alters the original obligation of the principal without the consent of
the guarantor, fails to inform the guarantor of material information pertinent
to the principal or any collateral, elects remedies that may impair the
subrogation rights of the guarantor against the principal or that may impair the
value of the collateral, fails to accord the guarantor the protections afforded
a debtor under the California Uniform Commercial Code or otherwise takes any
action that materially prejudices the guarantor. While we believe that express
and specific waivers of a guarantor's right to be exonerated, such as those
contained in the Guaranty, should be generally enforceable under California law,
we express no opinion as to whether the Guaranty contains an express and
specific waiver of each exoneration a





                                       -8-



<PAGE>   169


guarantor might assert in defense of a claim under a guaranty, or as to whether
each of the waivers contained in the Guaranty is fully enforceable. In addition,
we express no opinion with respect to the effect of (i) any modification to or
amendment of the obligations of the Borrower that materially increases such
obligations; (ii) any election of remedies by the Lender following the
occurrence of an event of default under the Credit Agreement; or (iii) any other
action by the Lender that materially prejudices O.S.I. Puerto Rico, if, in any
such instance, such modification, election, or action occurs without notice to
O.S.I. Puerto Rico and without granting O.S.I. Puerto Rico an opportunity to
cure any default by the Borrower.

         b. It could be contended that the Guaranty has not been given for a
fair or reasonably equivalent consideration, that O.S.I. Puerto Rico is, or, by
executing the Guaranty may become, insolvent, and that the Guaranty may be
violable by creditors of O.S.I. Puerto Rico or by a trustee or receiver of
O.S.I. Puerto Rico in bankruptcy or similar proceedings pursuant to applicable
bankruptcy, fraudulent conveyance or similar laws. Because of these possible
contentions, our opinion set forth in paragraph 3 below is further limited by
and subject to the effect of such laws.

         With respect to our opinion expressed in paragraph 1 below that the
Borrower is in good standing under the laws of the State of California, we have
relied solely upon the Certificate of Status (referred to above) of the
Secretary of State of the State of California dated October 23, 1996 to the
effect that the Borrower is duly incorporated and in good standing under the
laws of the State of California. With respect to our opinion expressed in
paragraph 1 below that the Borrower is duly qualified to do business in the
Commonwealth of Pennsylvania we have relied solely on the certificate of good
standing (referred to above) regarding the Borrower issued by the Pennsylvania
Secretary of State and dated October 24, 1996. With respect to our opinion
expressed in paragraph 1 below that O.S.I. Puerto Rico is in good standing under
the laws of the State of Delaware, we have relied solely upon the certificate
(referred to above) of the Secretary of State of the State of Delaware dated
October 25, 1996 to the effect that O.S.I. Puerto Rico is duly incorporated and
in good standing under the laws of the State of Delaware.

         We are admitted to practice law in the State of California. The
opinions expressed herein are limited to the existing laws of the State of
California, the Delaware General Corporation Law as in effect on the date
hereof, and (except as expressly set forth below) the existing federal laws of
the United States of America, assuming that such laws apply to the matters
expressed herein. We disclaim any opinion as to the laws of any other
jurisdiction. We have not conducted any special investigation of statutes, laws,
rules, or regulations and our opinion is limited to such California and United
States statutes, laws, rules or regulations, and provisions of the Delaware
General Corporation Law, as in our experience are of general application to
transactions of the sort contemplated by the Loan Documents. We also call your
attention to the fact that under various reports published by committees of the
State Bar of California, certain assumptions, qualifications and exceptions are
implicit in opinions of lawyers. Although we have expressly set forth certain
assumptions, qualifications and exceptions herein, we are not limiting or
omitting







                                       -9-



<PAGE>   170


any others set forth in the various reports or otherwise deemed standard by
practice for lawyers in California.

         In rendering the opinions below, we are opining only as to the specific
legal issues expressly set forth herein, and no opinion shall be inferred as to
any other matters.

         Based upon and subject to the foregoing, and subject to the
qualifications and exceptions contained herein, we are of the opinion that:

         1 . The Borrower is a corporation duly incorporated, validly existing
and in good standing under the laws of the State of California and has all
requisite corporate power and authority to carry on its business as it is
currently being conducted. O.S.I. Puerto Rico is a corporation duly
incorporated, validly existing and in good standing under the laws of the State
of Delaware and has all requisite corporate power and authority to carry on its
business as it is currently being conducted. The Borrower is duly qualified to
do business and is in good standing in the Commonwealth of Pennsylvania (which
the Borrower has represented in the Management Certificate to be the only
jurisdiction other than California in which the Borrower owns property, has
offices or employs employees).

         2. The execution, delivery and performance by the Borrower of each Loan
Document has been duly authorized by all necessary corporate action on the part
of the Borrower, The execution, delivery and performance by O.S.I. Puerto Rico
of the Guaranty has been duly authorized by all necessary corporate action on
the part of O.S.I. Puerto.

         3. The Loan Documents have been duly executed and delivered by
Borrower. The Guaranty has been duly executed and delivered by O.S.I. Puerto
Rico. The Loan Documents constitute legal, valid, and binding obligations of the
Borrower, enforceable against the Borrower in accordance with their respective
terms. The Guaranty constitutes a legal, valid, and binding obligation of O.S.I.
Puerto Rico, enforceable against O.S.I. Puerto Rico in accordance with its
terms.

         4. To our knowledge, the execution and delivery of the Loan Documents
by the Borrower, and the execution and delivery of the Guaranty by O.S.I. Puerto
Rico, does not (i) result in a breach of or constitute a default under or
(except as contemplated in the Loan Documents) require the creation of any lien,
charge or encumbrance on any property or assets of the Borrower or O.S.I. Puerto
Rico, pursuant to the terms of any of the Material Agreements, or (ii) violate
any law, statute, rule, or governmental regulation of the State of California or
the United States of America presently in effect and applicable to the Borrower
or O.S.I. Puerto Rico, except in each case for violations, breaches or defaults
that would not reasonably be expected to have a material adverse effect on the
Borrower. 


         5. No authorization or approval or other action by, and no notice to or
filing with, any United States federal or California governmental authority is
required in








                                      -10-


<PAGE>   171


connection with the execution and delivery of the Loan Documents by the Borrower
or the execution and delivery of the Guaranty by O.S.I. Puerto Rico, except for
filings required for the perfection of the liens and security interests granted
to the Lender under the Loan Documents.

         6. To our knowledge, there are no actions or proceedings against the
Borrower pending before any court, governmental agency or arbitrator which could
reasonably be expected to have a material adverse effect on the business,
operations, property or condition (financial or otherwise) of the Borrower
(except the Galley Litigation, as to which we render no opinion) or which
contest the legality, validity or enforceability of any Loan Document.

         7. Upon the proper filing and indexing of the Financing Statement in
the Office of the Secretary of State of California (assuming that the
representations made by Borrower with respect to the location of the Collateral,
its place of business and chief executive office are and remain true and
correct), the security interests granted by Borrower under the Pledge and
Security Agreement in and to such Collateral will constitute perfected security
interests therein to the extent that security interests in such Collateral may
be perfected by filing a financing statement under Division 9 of the California
Uniform Commercial Code.

         8. Assuming the Lender takes possession of and holds the shares of
capital stock of O.S.I. Puerto Rico listed on Schedule A to the Pledge and
Security Agreement (the "Pledged Shares"), delivered to the Lender pursuant to
the Pledge and Security Agreement, with undated stock powers duly endorsed in
blank, in the State of California, the Pledge and Security Agreement creates a
valid and perfected security interest in favor of the Lender in the Pledged
Shares.

         9. Neither Borrower nor O.S.I. Puerto Rico is an "investment company"
or a company "controlled" by an "investment company," within the meaning of the
Investment Company Act of 1940, as amended.

         10. The making of the Advances to the Borrower and the application of
the proceeds thereof by the Borrower pursuant to and in accordance with the
terms of the Credit Agreement does not violate Regulation G, T, U or X of the
Board of Governors of the Federal Reserve System.

         This opinion is intended solely for the benefit of the Lender for the
purpose of the financing contemplated by the Credit Agreement and is not to be
used by the Lender for any other purpose or made available to or relied upon by
any other person, firm or entity, without our prior written consent. We disclaim
any duty to update or advise the Lender of any fact, circumstance, event or
change in the law that may hereafter occur or be brought to our attention even
if it may affect or modify the opinions expressed herein.






                                Very truly yours,

Palo Alto, CA  94301-1825

                       Re:  O.S.I. Puerto Rico Corporation
                            BBH No. 80.7

Gentlemen:

                  We have acted as counsel to O.S.I. Puerto Rico Corporation
('OSI-PR') in connection with the proposed financing by and between O.S.I.
Corporation d/b/a Ocular Sciences/American Hydron ('OSI') and Comerica
Bank-California ('Comerica'). This opinion is delivered to you pursuant to the
provisions of the Credit Agreement of even date herewith (the 'Comerica Credit
Agreement').

                  The opinions expressed herein are qualified to the extent that
the validity or enforceability of any of the agreements, documents or
obligations referred to herein may be subject to or affected by applicable
reorganization, moratorium, bankruptcy, insolvency, or other laws relating to or
affecting the rights of creditors generally. We do not express any opinion on
the availability of any equitable (whether in a proceeding at law or in equity)
or other specific remedy upon breach of any of the agreements, documents or
obligations referred to herein.

                  On the basis of and subject to the foregoing, it is our
opinion that:

                  1. A court in the Commonwealth of Puerto Rico would enforce
the choice of law provision (i.e., California Law) contained in the Guaranty
Agreement of OSI dated as of October 30, 1996 (the "Guaranty").

                  2. The United States District Court in the Commonwealth of
Puerto Rico would enforce a judgment against OSI obtained in a United States
federal court in California with respect to the Guaranty. In the case of a
judgment rendered by a California state court, for



<PAGE>   174

the judgment to be enforceable in the Commonwealth of Puerto Rico an exequatur
petition would have to be filed in the General Court of Justice of the
Commonwealth of Puerto Rico in order to give full faith and credit to the
California judgment.

                  3. The filing of annual corporate reports with the Department
of State of the Commonwealth of Puerto Rico are required in order for a
corporation to be in good standing under the General Corporation Law of Puerto
Rico. According to the records of the Department of State, OSI-PR's annual
reports for the years 1991, 1993, 1994 and 1995 are outstanding and the firm of
KPMG Peat Marwick has been engaged to file the outstanding reports. Upon the
filing of these reports, OSI-PR will be in good standing under the laws of the
Commonwealth of Puerto Rico.

                  This opinion is issued solely for your information in
connection with the transaction described above and should not be quoted in
whole or in part or otherwise referred to in any financial statement or other
document or furnished to any other party or agency without our prior written
consent and with the consent of OSI-PR.

                  I am a member of the bar of the Commonwealth of Puerto Rico.
In rendering the foregoing opinions I have made no independent investigation of
any laws other than the laws of the Commonwealth of Puerto Rico and the General
Corporation Law of the Commonwealth of Puerto Rico.

                                        Very truly yours,

Dear Sirs

OSI CORPORATION (OSI) - EQUITABLE PLEDGE OF SHARES OF OCULAR SCIENCES LIMITED
(THE COMPANY)

1        INTRODUCTION

We have been asked to give an opinion in connection with an equitable pledge
(the CHARGE) of, inter alia, 1,950,000 ordinary shares of pound sterling1 each
in the capital of the Company comprising 65 per cent of the issued share capital
of the Company (the CHARGED SHARES) pursuant to a borrower pledge and security
agreement dated 30 October 1996 (the BORROWER PLEDGE AGREEMENT) between OSI and
Comerica Bank - California (the BANK) as part security for a loan facility of up
to US $27,000,000 from the Bank to OSI pursuant to a credit agreement likewise
dated 30 October 1996 between OSI and the Bank (the CREDIT AGREEMENT).

In this Opinion, reference to the DOCUMENTS shall be construed as reference to
the Credit Agreement and the Borrower Pledge Agreement.

Words and expressions defined in the Documents will, unless otherwise defined
herein, have the same meaning when used herein.

This opinion is given only in respect of the matters stated as at 30 October
1996 and on the basis of the law as it existed at that date.

We have been acting as legal advisers in England to OSI and the Company in
connection with the Charge to the extent addressed in this Opinion.

3.12 the accuracy and completeness of all factual representations contained or

October 1996 and proposed to be engaged thereafter.

3.14 that the Bank (pursuant to the Documents) is and will be a bona fide
purchaser or transferee for value of the Charged Shares and rights secured under

                                   - page 4 -
<PAGE>   179

completion by the Bank of the stock transfer form referred to in paragraph 2.10
and the registration in the register of members of the Company of the Bank as a
member of the Company following the delivery by the Bank of such stock transfer
form, duly stamped and the share certificates referred to in paragraph 2.11 to

We have made such examination of the laws of England as currently applied by
English Courts as in our judgement is necessary for the purpose of this opinion.
We do not however purport to be qualified to pass upon and express no opinion
herein as to the laws of any jurisdiction other than those of England. This
Opinion is governed by and shall be construed in accordance with English law.

4        OPINIONS

Based upon and subject to the foregoing and further subject to the assumptions
and qualifications in this Opinion and having regard to such legal
considerations as we have deemed relevant, we are of the opinion that: -

4.1 the Company is a company duly incorporated under the laws of England as a
private limited liability company and is validly existing thereunder. As at 17
October 1996, the Company was in Good Standing as herein define. By GOOD
STANDING (a phrase which has no recognised meaning under English law), we mean
that according to a certificate dated 17 October 1996 from the Registrar of
Companies, the Company has been in continuous and unbroken existence since the
date of its incorporation on 25 April 1985 and that there is no document on the
public file showing the institution of any proceedings for the winding up or
liquidation of the Company or that the Company is not still in operation.

4.2 the Charged Shares have been duly authorised for issuance by the Company and
have been issued to OSI fully paid up or credited as fully paid up.

4.3 Under the laws of England, there are no legal restrictions on the Transfer
of the Charged Shares pursuant to the proper and valid enforcement of the Charge
and the Transfer of the Charged Shares in manner aforesaid does not require any
governmental approval or authorization in England, and the Memorandum and
Articles of Association of the Company do not contain any restrictions on the
Transfer of the Charged Shares in manner aforesaid and do not require any
approval or other authorisation of the members of the Company in connection
therewith.

4.4 The execution by OSI of the Borrower Pledge Agreement and delivery of the
same together with the delivery of the share certificates referred to in
paragraph 2.11 and the stock transfer form referred to in paragraph 2.10 to the
Bank create a valid equitable pledge of the Charged Shares under the laws of
England, enforceable in England.

4.5 All actions of the Company and OSI required by the laws of England in
respect of the Charge to create a valid and enforceable equitable pledge under
the laws of England have been duly taken by the Company and OSI.

4.6 Until the occurrence of: -



                                   - page 5 -
<PAGE>   180

4.6.1 any Event of Default (as defined in the Borrower Pledge Agreement);

4.6.2 any other event entitling the Bank to enforce the Charge; or

4.6.3 any Transfer of the Charged Shares to the Bank

the Charge will not result in the imposition upon the Bank of any liability
applicable to membership of the Company for capital contributions to the
Company, for funding any unfunded obligations of the Company or for any other
liability of the Company.

5        QUALIFICATIONS

The opinions expressed herein are subject to the following qualifications: -

5.1 the validity and enforcement of any of the Documents may be limited by
statutes of limitation, lapse of time and by laws relating to bankruptcy,
insolvency, liquidation, arrangement, moratorium, re-organisation or other laws
relating to or affecting generally the enforcement of the rights of creditors,
and claims may be or become subject to set-off or counterclaim;

5.2 equitable remedies, such as injunction and specific performance, are
discretionary and may not necessarily be awarded by the English Courts; in
particular, such remedies may not be available where damages are considered to
be an adequate and appropriate remedy;

5.3 a provision that a calculation, determination or certificate will be
conclusive and binding will not apply to a calculation, determination or
certificate which is given unreasonably, arbitrarily or without good faith or
which is fraudulent or manifestly inaccurate and will not necessarily prevent
judicial enquiry into the merits of any claim;

5.4 failure to exercise a right may operate as a waiver of that right
notwithstanding a provision such as section 8.5 of the Borrower Pledge
Agreement.

5.5 we express no opinion on the accuracy or completeness of any statements or
warranties of fact set out in the Documents, which statements and warranties we
have not independently verified;

5.6 we express no opinion on any provision in any of the Documents requiring
written amendments and waivers of such documents insofar as it suggests that
oral or other modifications, amendments or waivers could not be effectively
agreed upon or granted by or between the parties;

5.7 where any party to any of the Documents is vested with a discretion or may
determine a matter in its opinion, Courts in England may require that such a
discretion be exercised reasonably or that such an opinion be based on
reasonable grounds;

5.8 An English Court would determine in its discretion whether or not an
invalid, illegal or unenforceable provision may be severed or be partially
effective, notwithstanding a provision such as section 8.7 of the Borrower
Pledge Agreement;



                                   - page 6 -
<PAGE>   181

5.9 the exercise by the Bank of the powers and remedies conferred on it by each
of the Documents or otherwise vested in it by law will be subject to general
equitable principles regarding the enforcement of security and the general
supervisory powers and discretion of the English Courts in the context thereof
and we express no opinion as to the efficacy of any powers conferred upon or the
Bank or any receiver, administrative receiver or similar officer appointed under
the Documents insofar as these powers go beyond those conferred by statute or by
common law;

5.10 an English Court may not award by way of costs all of the expenditure
incurred by a successful litigant in proceedings brought before the Court and an
undertaking by any party to the Documents to bear any indemnity in respect of
any taxes or duties might not be enforceable in respect of United Kingdom stamp
duties, pursuant to Section 117 of the Stamp Act 1891, if such were imposed in
the future;

5.11 the opinion expressed in paragraph 4.1 that the Company is a company duly
incorporated under English law is based on the assumption set out in paragraph
3.8, on our telephone enquiry made on 30 October 1996 confirming that no winding
up petition had been presented in respect of the Company but otherwise solely
upon the result of a search conducted by our agents at the Companies Registry on
28 October 1996. It should be noted that: -

5.11.1 a search at the Companies Registry is not capable of revealing whether or
not a winding-up petition or a petition for the making of an administration
order has been presented; and

5.11.2 notice of a winding-up order or resolution, notice of an administration
order and notice of the appointment of a receiver may not be filed at the
Companies Registry immediately and there may be delay in the relevant notice
appearing on the file of the relevant party;

5.12     we express no opinion as to:

5.12.1 the priority of any of the security created by the Borrower Pledge
Agreement;

5.12.2 the legality, validity, binding nature or enforceability of the payment
obligations contained in the Documents;

5.12.3 the efficacy of the Borrower Pledge Agreement in relation to any property
other than the Charged Shares;

5.13 unless and until the Charged Shares are registered in the register of
members of the Company in the name of the Bank the Charge will take effect as an
equitable charge and may be defeated by interests acquired by third parties
without notice of the Charge;

5.14 we express no opinion as to whether any provision in the Documents
conferring a right of set-off or similar right would be effective against a
liquidator, administrator or a creditor;

5.15 as regards the enforcement of a judgment of a foreign Court, the Courts of
England will not simply register and enforce such judgment. It would be
necessary to commence fresh



                                   - page 7 -
<PAGE>   182

proceedings before the English Courts, in which the foreign judgment would be
evidence of liability, subject to satisfaction of the following criteria: -

5.15.1 the procedural rules for commencement and maintenance of proceedings
before the English Courts would need to be observed;

5.15.2 the foreign Court must properly have had jurisdiction to hear and
determine the matter;

5.15.3 the decision of the foreign Court must have been final and conclusive;

5.15.4 the decision of the foreign Court must have been for a fixed sum only;

5.15.5 the decision of the foreign Court must not have been obtained by fraud or
by a trick;

5.15.6 the decision of the foreign Court must not be contrary to public policy
or have been given in proceedings of a penal or revenue nature; and

5.15.7 the decision of the foreign Court must not be contrary to natural
justice;

5.16 the Transfer of the Charged Shares to the Bank will attract ad valorem
stamp duty at the rate of 50 pence for each pound sterling100 (or part thereof)
of consideration and accordingly the Bank will be required to submit the stock
transfer form referred to in paragraph 2.10 for stamping and pay the duty
thereon prior to being entitled to be registered as a member of the Company in
the register of members of the Company.

5.17 The Company's loan facility from Midland Bank Plc (MIDLAND) contains a
provision which would entitle Midland to withdraw the facility in the event of a
change of control of the Company. There is no definition of "control" in the
Midland loan documentation. However, it is likely that control would be deemed
to change if the Charged Shares were registered in the name of the Bank.

This Opinion is given for the sole benefit of the Bank in connection with the
transactions contemplated by the Credit Agreement. This Opinion is not to be
disclosed to any other person nor is it to be relied upon by any other person or
for any other purpose or quoted or referred to in any public document without
our prior written consent.
