                               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. 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
marketed 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. These
strategies provide 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
needs 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 28% from 1987 to 1997, according to Health
Products Research, a market research firm, largely as a result of the
introduction in 1988 of soft contact lenses marketed 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 offered by competing distribution channels. Accordingly, the Company
has successfully implemented a strategy to address the needs of eyecare
practitioners. The Company markets its lenses solely to eyecare
 
                                        4
<PAGE>   6
 
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 annual replacement segment of the United States market with a
market share estimated at approximately 24% of total unit sales in the fourth
quarter of 1997. Since its introduction of lenses marketed for weekly disposable
replacement regimens in 1993, the Company has steadily increased its share of
this growing market, reaching approximately 12% of total unit sales in the
United States during the fourth quarter of 1997, 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 69% from 1993 through 1997,
primarily due to increased sales of its lenses marketed for weekly disposable
replacement regimens. During the same period, while the overall average selling
prices of all of the Company's lenses declined approximately 59%, the Company
reduced its per unit production costs by approximately 73% 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 1993 through 1997, the Company's net sales and operating income
have increased at compound annual growth rates of approximately 33% and 80%,
respectively, while its operating margins have improved from 7.5% to 25.2% (in
each case excluding non-recurring charges in 1993). 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 marketed 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.
 
RECENT DEVELOPMENTS
 
     On January 29, 1998, the Company announced that its net sales in 1997 were
$118.6 million, representing an increase of 31.0% over net sales of $90.5
million in 1996. Substantially all of this growth resulted from increased sales
of the Company's lenses marketed for weekly disposable replacement regimens.
Gross profit increased 43.7% to $77.5 million, or 65.4% of net sales in 1997,
from $54.0 million, or 59.6% of net sales in 1996. The increase in gross profit
from 1996 to 1997 was due primarily to increased net sales, and decreases in per
unit production costs resulting from the implementation of certain process
improvements and increases in manufacturing volume. Income from operations
increased 71.7% to $29.9 million in 1997 from $17.4 million in 1996, and net
income increased 102.8% to $20.6 million in 1997 from $10.2 million in 1996.
 
     In August 1997, the Company consummated its initial public offering, in
which the Company sold 3,600,000 shares of Common Stock and selling stockholders
sold 4,680,000 shares of Common Stock, at an initial public offering price of
$16.50 per share. The net proceeds to the Company of $53.7 million were used to
repay indebtedness, and are being used for expansion and automation of
manufacturing facilities and other general corporate purposes.
 
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 replacement market.
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 unit shipped for
     disposable replacement regimens, the Company can identify diversion of its
     lenses to non-eyecare practitioner channels. The Company
 
                                        5
<PAGE>   7
 
     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 Brand Segmentation by Channel. The high-volume use of lenses
     marketed 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 marketed 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 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 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, scaleable manufacturing
     has become increasingly important. The Company's dry cast molding
     technology allows it to manufacture high-quality lenses efficiently. As a
     result, the Company has been able to reduce its per unit production costs
     by approximately 73% over the last four years while increasing its
     production volumes by approximately 876%. The Company plans to implement
     highly automated production lines in its U.K. manufacturing facility,
     beginning in the second quarter of 1998, and plans to relocate its Puerto
     Rican manufacturing operations to a substantially larger new facility,
     which will also include these highly automated production lines, in 1999.
     The Company believes that the increased unit volumes resulting from the
     growing disposable replacement regimen market and this 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 since 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 marketing solely to the eyecare practitioners who prescribe
     contact lenses. In addition, the Company continues to invest 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 lenses marketed for
     disposable replacement regimens in developed markets such as Europe, Japan
     and Canada and by increased disposable income in emerging markets in 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 Carl Zeiss Company ("Zeiss") in Europe and Seiko Contactlens,
     Inc. ("Seiko") in Japan, to capitalize on their existing market presence,
     customer relationships and local infrastructure. The Company anticipates
     that Seiko will receive initial approval to sell certain of the Company's
     contact lenses marketed for disposable replacement regimens in Japan by the
     fourth quarter of 1998. The Company has also established distribution
     relationships with other soft contact lens distributors in a number of
     countries in the Asian market. 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 was reincorporated in Delaware in July 1997. The
Company's principal executive offices are located at 475 Eccles Avenue, South
San Francisco, California 94080, and its telephone number is (650) 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 or implied in such
forward-looking statements due to such risks and uncertainties. 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. As the
number of wearers of soft contact lenses in the United States ("U.S.") has not
grown significantly in recent years, increased U.S. market penetration by the
Company will require wearers of competing products to switch to the Company's
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"), Wesley Jessen VisionCare, Inc. ("Wesley Jessen") and The Cooper
Companies, Inc. ("Cooper"). Many 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 marketed for disposable replacement regimens, where
the Company is less experienced and has a significantly smaller market share.
The disposable replacement market 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 replacement market 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 replacement market are marketed
for weekly and monthly replacement regimens. Certain of the Company's
competitors have introduced lenses marketed for daily replacement at lower
prices than their lenses currently marketed for weekly and bi-weekly disposal.
Recently, Ciba-Geigy has introduced a lower-priced lens marketed for daily
replacement in the U.S. market, and Bausch & Lomb has begun selling lenses
marketed for daily replacement in certain European markets. The Company is
evaluating the introduction of a lens marketed for daily disposal
 
                                        9
<PAGE>   11
 
regimens. 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 marketed for different replacement
regimens are often similar, the ability of competitors to reduce their per unit
costs for lenses marketed for daily disposal 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 affect the
Company's ability to compete in selling lenses for a much broader range of
replacement regimens. See "-- Dependence on Single Product Line; Need to
Increase Sales of Lenses for Disposable Replacement Regimens."
 
     In December 1997, Cooper acquired Aspect Vision Care Ltd. ("AVCL"), a
U.K.-based manufacturer and marketer of soft contact lenses. AVCL's
manufacturing process technology and lens designs are based in part on
technology also licensed to, and used by, the Company. AVCL was, until recently,
contractually prohibited from selling lenses in the U.S. See "Certain
Transactions -- OSL Acquisition and Related Litigation." Cooper has recently
announced that it has introduced a new line of contact lenses marketed in the
U.S. for weekly and monthly replacement regimens that utilize AVCL's
manufacturing process technology and lens designs, and that this new line will
provide practitioners with products that are proprietary to their practice.
 
     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 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 has encountered certain delays in implementing these
automated lines, and there can be no assurance that it will not encounter
significant delays and difficulties in the future. 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 longer design time than anticipated, or 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 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 that from 1998 through the end of 2000, it
will invest approximately $64.0 million in capital expenditures on automated
production lines in the United Kingdom and Puerto Rico and expects to continue
to invest in additional automated production lines after this period. The
Company intends to finance these capital expenditures with net cash provided by
operating activities, existing cash
 
                                       10

balances and 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. As a result, the Company intends to relocate its Puerto Rican
manufacturing operations to a substantially larger new facility to be
constructed to the Company's specifications and leased to the Company by the
Puerto Rico Industrial Development Company. The Company has entered into a
letter of intent, and is negotiating the final terms of the lease for the
facility. The Company began construction of the new facility in January 1998 and
expects to complete construction, and initial installation of equipment, by the
second quarter of 1999. However, the Company has encountered certain delays in
the construction of the facility, and there can be no assurance as to when it
will complete construction and commence production. Before this new facility
begins production, it will be inspected by the U.S. Food and Drug Administration
(the "FDA") for compliance with the FDA's quality system regulation, which
includes current good manufacturing practice ("GMP") requirements, and
determined by the FDA to be in compliance with this regulation. The inspection
process and determination of compliance by the FDA 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. Given the long lead times associated with constructing a new
facility, as well as delays while seeking FDA clearance or approval of new or
modified products, the Company will incur substantial cash expenditures before
it commences production of commercial volumes of contact lenses 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 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 materially 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 lawsuit 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. See
"Business -- Sales and Marketing." One of the defendants has agreed to settle
the lawsuit 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
 
                                       11
<PAGE>   13
 
available to consumers. The lawsuit has been consolidated with certain related
lawsuits, including several class action lawsuits, and trial has been set for
April 1999 in Florida.
 
     In an unrelated matter, one of the Company's largest competitors was sued
in a national 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. In August 1997, such competitor also
settled an investigation by 17 states into similar matters by agreeing to
certain significant restrictions on its future contact lens marketing practices
and making certain payments to each of the states. In October 1996, a class
action lawsuit was brought against another of the Company's largest competitors
in the Superior Court of New Jersey-Camden (the "New Jersey Lawsuit"). This suit
alleges that the defendant engaged in fraudulent and deceptive practices in the
marketing and sale of contact lenses by selling interchangeable contact lenses,
under different brand names and for different replacement regimens, at different
prices. The suit was certified as a national class action in December 1997. 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 and
New Jersey Lawsuits, 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. Additionally, the lawsuits against certain of
the Company's competitors have generated, and may continue to generate,
unfavorable publicity for the contact lens industry, which publicity could
increase the possibility of trade practice-related litigation or governmental
action. The defense of any trade practice-related 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 action, 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 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
Marketed 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
 
                                       12
<PAGE>   14
 
prices by its competitors, the acceptance 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 marketed 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
demand for contact lenses for annual replacement regimens will continue to
contract in its major geographic markets as wearers continue to shift to
disposable replacement regimens. The Company, a relatively recent entrant in the
disposable replacement market, 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. The Company anticipates that prices for its products marketed for
disposable replacement regimens will decline in the future. There can be no
assurance that the Company's contact lenses marketed for disposable replacement
regimens will achieve widespread consumer acceptance, or that net sales or net
income from the sale of the Company's lenses marketed for disposable replacement
regimens will be sufficient to offset the decline in the Company's net sales or
net income from its contact lenses marketed for annual replacement regimens,
which have higher prices and gross margins. Any such failure to achieve broad
market acceptance or to capture a significant share of the disposable
replacement market 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. The lenses currently
offered in the U.S. by the Company in the disposable replacement market are
marketed for weekly and monthly replacement regimens. Certain of the Company's
competitors have introduced lenses marketed for daily replacement at lower
prices than their lenses currently marketed for weekly and bi-weekly regimens.
The Company is evaluating the introduction of a lens for daily disposal
regimens. The Company's ability to enter and to compete effectively in the daily
disposable market will depend in large part upon the Company's ability to expand
its production capacity and reduce its per unit production costs. 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
marketed for disposable replacement regimens with an ultraviolet light
inhibitor, which could increase the appeal of its products. The Company is
developing lenses with a similar feature, but 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 Bausch & Lamb 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 develop its own technology or 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 Marketed 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
 
                                       13
<PAGE>   15
 
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 net 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. Consistent with its historical seasonality, the Company
expects its net sales for the quarter ending March 31, 1998 to be lower than its
net sales for the quarter ended December 31, 1997. The Company believes that the
historical increases in sales of its products in the third and fourth quarters
have been primarily 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 marketed 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 marketed for annual replacement regimens to
lenses marketed for disposable replacement regimens and, within the disposable
segment, to lenses that are marketed for more frequent replacement, (ii)
decreases in the prices of lenses marketed for disposable replacement regimens
and (iii) increases in products sold internationally through distributors at
prices lower than direct sales prices in the U.S. The Company does not expect
there to be significant growth in its sales of lenses marketed for annual
replacement. 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 1997, the Company's international sales
represented approximately 18.7%, 18.2% and 21.0%, 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 materially 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
 
                                       14
<PAGE>   16
 
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.
 
     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. The Company's sales to many of
its distributors are made pursuant to short-term agreements or purchase orders.
There can be no assurance that any such agreements will be renewed or replaced
upon their expiration or that the volume of purchases by any distributor will
not decline in future periods. 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, financial and management information
systems. See "Business -- Employees."
 
     The Company is in the process of replacing its information systems with new
systems that are expected to include a number of integrated applications,
including order entry, billing and labeling. 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
and integration of these applications will be important to facilitate future
growth. The Company has implemented several of these applications, and
anticipates implementing the other planned applications by the end of 1999.
However, the Company could experience unanticipated delays in the implementation
of the new systems and implementation of the new 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. In addition, delays in implementing the new
systems could require additional expenditures by the Company to modify or
replace portions of its existing information systems so that they will function
properly with respect to dates in the year 2000 and thereafter and there can be
no assurance that the Company will be able to correct any problems with respect
to such dates in a timely manner.
 
                                       15
<PAGE>   17
 
     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.
 
     The Company may discover 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, prior to its 1997 acquisition by Cooper, the
patent owners had a significant interest in AVCL, a United Kingdom company that
competes with the Company in certain markets and that was, until recently,
contractually prohibited from selling certain lenses in the U.S. See "Certain
Transactions -- OSL Acquisition and Related Litigation." In 1997, AVCL was
acquired by Cooper and Cooper has recently announced that it will use AVCL's
technology, which the Company believes includes the licensed technology, to
compete in the U.S. See "-- Intense Competition." 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 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.
 
                                       16
<PAGE>   18
 
     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 Federal Food, Drug and Cosmetic Act (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,
distribution, sales and marketing), product seizures and criminal prosecution of
a company and its officers and employees. 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 U.S. 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 U.S. market through the
submission of a Section 510(k) Pre-Market Notification (a "510(k)
notification"); exempted from the requirement of such clearance; 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) 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
 
                                       17
<PAGE>   19
 
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 quality system
(including GMP) requirements in future inspections by regulatory authorities,
and noncompliance with quality system (including 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 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 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. 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 $500,000
Canadian dollars 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 scarring and 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.

     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 Chief Executive
Officer, could have a material adverse effect on the Company. See
"Business -- Employees" and "Management."
 
     Influence by Existing Stockholders. After completion of this offering, the
directors, officers and principal stockholders of the Company will, in the
aggregate, beneficially own approximately 38.8% of the Company's outstanding
Common Stock (approximately 36.1% if the Underwriters' overallotment option is
exercised in full). As a result, these stockholders, acting together, will
possess significant voting influence over the election of the Company's Board of
Directors and the approval of significant corporate transactions, among other
matters. Such influence 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. The Company's Board of Directors has 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 are 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. 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. This
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. Upon completion of
this offering, the Company will have 21,897,816 shares of Common Stock
outstanding. Of these shares, 12,489,042 shares of Common Stock (13,093,542
shares if the Underwriters' overallotment option is exercised in full) will be
freely tradable without restriction under the Securities Act of 1933, as amended
(the "Securities Act"). Subject to certain 90-day "lock-up" agreements,
approximately             of the remaining shares of Common Stock held by
existing stockholders of the Company are currently eligible for sale in the
public market.             of such shares are subject to compliance with the
resale volume limitations of Rule 144 under the Securities Act (            of
which are subject to 90-day lock-up agreements) and             of such shares
may be sold without regard to such limitations. The holders of an aggregate of
approximately 8,266,358 shares of Common Stock following this offering have
certain rights to require the registration of their shares of Common Stock under
the Securities Act at the Company's expense. Future sales of the shares of
Common Stock held by existing stockholders 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."

     Volatility of Stock Price. The market price of Company's Common Stock is,
and is likely to continue 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, trade
practice litigation, 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 "Price Range of Common Stock."

                                USE OF PROCEEDS
 
     The net proceeds to the Company from the sale of the 30,000 shares of
Common Stock offered by the Company hereby are estimated to be approximately
$684,000 (at an assumed public offering price of $24.00 per share and after
deducting estimated underwriting discounts and commissions but before deducting
estimated expenses of $540,000). 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 the net
proceeds to it from this offering primarily to pay the estimated expenses
incurred by the Company in this offering.
 
                          PRICE RANGE OF COMMON STOCK

                                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 Company's Amended and Restated Credit Agreement with Comerica
Bank -- California (the "Comerica Credit Agreement'). 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.

                      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 the discussion of 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 its prior owners 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 then 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 North and South American contact
lens business of Allergan, Inc. ("Allergan"), 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 3,403,192 shares of Common Stock,
118,168 shares of 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 note was repaid with bank borrowings
in 1993 and the senior subordinated notes were repaid with bank borrowings in
1996. The Preferred Stock was converted into Common Stock upon the consummation
of the Company's initial public offering. The American Hydron acquisition
resulted in goodwill and other intangible assets of $3.4 million, all of which
were 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 marketed for annual replacement regimens and the remainder
of its sales from lenses marketed for monthly disposable replacement regimens.
In the third quarter of 1993, the Company began selling lenses marketed for
weekly disposable replacement regimens. Since that time, substantially all of
the Company's growth in net sales has resulted from sales of lenses marketed for
disposable replacement regimens, primarily weekly disposable replacement
regimens. In the first quarter of 1995, the Company introduced a second line of
lenses marketed for weekly disposable replacement regimens. The Company's lenses
marketed for disposable replacement regimens historically have had lower selling
prices and gross margins and are sold in much greater volumes than its lenses
marketed for annual replacement regimens. In 1997, lenses marketed for
disposable replacement regimens accounted for 89.6% of the Company's unit volume
and 75.9% of net sales. See "Risk Factors -- Dependence on Single Product Line;
Need to Increase Sales of Lenses Marketed for Disposable Replacement Regimens."
In 1997, approximately 54% of the Company's U.S. net sales came from sales to
 
                                       24
<PAGE>   26
 
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, among
other things, for (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 in February 1997 and paid an additional $6.7 million in August 1997.
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 16 of Notes to Consolidated
Financial Statements. The Company is amortizing these intangible assets over a
ten-year period. In connection with the U.K. Litigation, the Company incurred
legal expenses of $1.3 million, $2.5 million and $56,000 in 1995, 1996 and 1997,
respectively, which are included in the Company's general and administrative
expenses. See "Certain Transactions -- OSL Acquisition and Related Litigation."

</TABLE>
 
     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 31.0% to $118.6 million in 1997 from $90.5 million in 1996.
Substantially all of this growth resulted from increased sales of the Company's
lenses marketed for weekly disposable replacement regimens. The Company's
international sales as a percentage of total sales increased from 18.2% in 1996
to 21.0% in 1997 primarily as a result of increased demand experienced by the
Company's international distributors and new partnering and distributor
relationships established by the Company abroad. See "Risk Factors -- Risks
Relating to International Operations; Need to Increase Sales in International
Markets." In 1997, 89.6% of all lenses sold by the Company were marketed for use
in disposable replacement regimens, compared to 83.5% in 1996. The Company's
overall average selling price declined approximately 11.2% from 1996 to 1997,
primarily as a result of a shift in product mix from lenses marketed for annual
replacement regimens to lower priced lenses marketed for disposable replacement
and, to a lesser extent, as a result of an increase in the percentage of the
Company's products sold internationally to distributors at prices lower than
direct sales prices in the United States. Within each principal distribution
channel, the average selling price of each of the Company's
 
                                       25
<PAGE>   27
 
primary products remained relatively stable from 1996 to 1997. The Company
expects that the overall average selling price that it realizes across its
products will continue to decline over time, and may decline at a greater rate
than in the past, because of (i) shifts in the Company's product mix from lenses
marketed for annual replacement regimens to lenses marketed for disposable
replacement regimens and, within the disposable category, to lenses marketed for
more frequent replacement, (ii) decreases in the average per unit selling prices
of lenses marketed for disposable replacement regimens and (iii) increases in
products sold internationally to distributors at lower prices than direct sales
prices in the United States. The Company does not expect there to be significant
growth, if any, in its sales of lenses marketed for annual replacement regimens
as a result of the continuing shift in consumer demand towards more frequent
replacement regimens. Historically, the Company's first quarter net sales have
been lower than its fourth quarter net sales, and the Company expects that its
net sales for the quarter ending March 31, 1998 will be lower than its net sales
for the quarter ended December 31, 1997. In addition, the Company does not
believe that its net sales growth rate from 1996 to 1997 is indicative of the
Company's long-term sales growth rate.

        As a percentage of net sales................     59.6%                    65.4%
</TABLE>
 
     Cost of sales is comprised primarily of the labor, overhead and material
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 43.7% to $77.5 million, or 65.4% of net sales in 1997, from $54.0
million, or 59.6% of net sales, in 1996. The increase in gross profit from 1996
to 1997 was due primarily to increased net sales, and to decreases in per unit
production costs resulting from the implementation of certain process
improvements and increases in manufacturing volume. The Company expects cost
reductions resulting from the Company's current production process to be less
significant in the immediate future. The Company intends to add new, highly
automated production lines at its United Kingdom and Puerto Rico facilities,
which are designed to reduce further its per unit cost of production over time,
and anticipates installing the first such line in the second quarter of 1998. As
the Company expects that its overall average selling price will continue to
decline over time, and anticipates higher depreciation, which is a component of
cost of sales, as a result of significantly increased investment in property and
equipment, 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." In addition, the Company may experience
decreased per unit prices in future periods, while not achieving comparable
decreases in its cost of sales until subsequent periods, if at all. As a result,
the Company would experience significant variability in its gross margins. For
example, if the Company introduces a lower-priced contact lens marketed for
daily replacement regimens, its average selling price will decline, and may
decline significantly, while reductions in costs of sales would likely not reach
comparable levels until subsequent periods, if at all. Accordingly, the Company
would expect its gross margins to decrease in the short term following the
introduction of lenses marketed for daily replacement regimens. See "Risk
Factors -- Fluctuations in Operating Results; Seasonality; Decreasing Average
Sales Prices."
 
     In the fourth quarter of 1997, the Company finalized plans to change the
packaging component of its manufacturing process in late 1998, resulting in an
$824,000 write-down in 1997 of certain of its manufacturing assets to estimated
fair value and a corresponding $824,000 increase in cost of sales. See Note 5 of
Notes to Consolidated Financial Statements. In addition, cost of sales in 1997
included approximately $690,000 for amortization of intangible assets acquired
in connection with the settlement of the U.K. Litigation, and the Company
anticipates amortizing approximately $860,000 per year over the remainder of the
ten-year useful life of these intangible assets. See "-- Overview."

</TABLE>
 
     Selling and marketing expenses are comprised primarily of cooperative
merchandising allowances, sample diagnostic products provided to eyecare
practitioners without charge, salaries, commissions and benefits for selling and
marketing personnel 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 marketed for disposable replacement regimens. These allowances are
limited to a percentage of purchases of lenses marketed for disposable
replacement regimens from the Company. Selling and marketing expenses increased
49.9% to $27.1 million, or 22.9% of net sales, in 1997 from $18.1 million, or
20.0% of net sales, in 1996. The increase, both in absolute dollars and as a
percentage of net sales from 1996 to 1997 resulted primarily from an increase in
cooperative merchandising allowances and, to a lesser extent, an increase in the
shipment of sample diagnostic products. The Company expects selling and
marketing expenses, particularly cooperative merchandising allowances, to
continue to grow at a faster rate than its net sales as the Company seeks to
increase its market share.

        As a percentage of net sales................       20.4%                    17.3%
</TABLE>
 
     General and administrative expenses are comprised primarily of salaries and
benefits for distribution, general and administrative and research and
development personnel, professional services, consultants' fees and
non-manufacturing facilities costs. General and administrative expenses
increased 11.1% to $20.5 million in 1997 from $18.4 million in 1996, but
declined as a percentage of net sales from 20.4% to 17.3%. The dollar increase
was due primarily to increased salaries and other personnel-related benefits to
employees, increases in research and development related to the Company's
ongoing focus on reducing per unit costs of production, sales and use tax
provisions, fees to regulatory consultants, relocation and recruiting fees
associated with the hiring of a new chief operating officer, and increased
depreciation, partially offset by reductions in legal and professional fees as a
result of the settlement of the U.K. Litigation in February 1997. The decrease
in the percentage of net sales resulted from the limited growth in distribution
and administrative expenses relative to the growth in net sales. The Company
believes that its general and administrative expenses will increase in absolute
dollars, in part as a result of the expenses associated with being a public
company, and are expected to decrease as a percentage of net sales if net sales
grow as expected.

     Interest and other expense, net decreased 86.1% to $454,000, or 0.4% of net
sales, in 1997 from $3.3 million, or 3.6% of net sales, in 1996. This decrease
primarily resulted from a reduction in interest expense as the aggregate amount
of the Company's borrowings was reduced following its initial public offering in
August 1997 and an increase in interest earned as a result of the investment of
a portion of the net proceeds from the Company's initial public offering.

</TABLE>
 
     Income taxes were $8.8 million in 1997 and $4.0 million in 1996. The
Company's effective tax rate increased from 28.2% in 1996 to 30.0% in 1997 as a
result of an increase in the percentage of international earnings, which are
subject to full U.S. taxation, as compared to earnings attributable to the
Company's Puerto Rican operations, which are partially exempt from U.S.
taxation. The Company anticipates that it will continue to benefit from the
favorable effect of this partial exemption through 2001, when its benefit will
expire under the current provisions of the Internal Revenue Code. 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
reduction in the Company's labor costs in Puerto Rico relative to its Puerto
Rican earnings. See Note 13 of Notes to Consolidated Financial Statements.

     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 lenses marketed for weekly disposal regimens. The overall average
price of the Company's lenses marketed for weekly disposable replacement
regimens was

similar in 1995 and 1996. The Company's sales of lenses marketed for annual
replacement regimens declined slightly in both volume and average price from
1995 to 1996. The Company's international sales represented approximately 18.7%
and 18.2% of the Company's net sales in 1995 and 1996, respectively.

</TABLE>
 
     Gross profit increased 30.7% 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 in unit cost of sales. The reduction in overall average
selling price of 13.2% was caused by an increased percentage of lenses marketed
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 a postponement by the FDA of its GMP inspection of the Company's new
United Kingdom facility, and this delay prevented the reduction in per unit cost
of sales from completely offsetting the reduction in average selling price as
planned. Additionally, the Company recorded provisions in 1996 totaling
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 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 lenses marketed for disposable replacement regimens, which grew at rates in
excess of the Company's overall net sales. 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 increased 28.9% to $18.4 million in
1996 from $14.3 million in 1995, but decreased as a percentage of net sales to
20.4% 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 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

resulted from an increase in earnings attributable to the Company's Puerto Rican
operations, which are partially exempt from United States income taxation.

</TABLE>
 
     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 net 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. Consistent with its historical seasonality, the Company expects its
net sales for the quarter ending March 31, 1998 to be lower than its net sales
for the quarter ended December 31, 1997. The Company believes that the
historical increases in sales of its products in the third and fourth quarters
have been primarily 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
 
                                       31
<PAGE>   33
 
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,
and if it continues the pattern may be somewhat less pronounced if the Company
continues to increase the proportion of sales represented by more frequently
replaced lenses marketed for disposable replacement regimens. See "Risk
Factors -- Fluctuations in Operating Results; Seasonality; Decreasing Average
Sales Prices."
 
RECENTLY ISSUED ACCOUNTING PRONOUNCEMENT
 
     In June 1997, the Financial Accounting Standards Board issued SFAS Nos. 130
and 131, "Reporting Comprehensive Income" ("SFAS No. 130") and "Disclosures
about Segments of an Enterprise and Related Information" ("SFAS No. 131"),
respectively (collectively, the "Statements"). The Statements are effective for
fiscal years beginning after December 15, 1997. SFAS No. 130 establishes
standards for reporting of comprehensive income and its components in annual
financial statements. SFAS No. 131 establishes standards for reporting financial
and descriptive information about an enterprise's operating segments in its
annual financial statements and selected segment information in interim
financial reports. Reclassification or restatement of comparative financial
statements or financial information for earlier periods is required upon
adoption of SFAS No. 130 and SFAS No. 131, respectively. Application of the
Statements' disclosure requirements will have no impact on the Company's
consolidated financial position, results of operations or earnings per share
data as currently reported.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     Cash and cash equivalents at December 31, 1997 of $27.9 million increased
from a December 31, 1996 balance of $3.8 million. The restricted cash held in
escrow for the rent of the Company's United Kingdom facility at December 31,
1997 of $0.5 million was reduced from $1.7 million at December 31, 1996. Working
capital increased from $15.1 million at December 31, 1996 to $56.0 million at
December 31, 1997. The increase in both cash and cash equivalents and working
capital from 1996 to 1997 was primarily attributable to the Company's sale of
3.6 million shares of Common Stock in its August 1997 initial public offering,
partially offset by the repayment of debt then outstanding under the Comerica
Credit Agreement and to the Company's Chief Executive Officer, the final payment
for intangible assets pursuant to the settlement of the U.K. Litigation and
investments in long-term securities. See Note 14 of Notes to Consolidated
Financial Statements.
 
     From January 1, 1995 to December 31, 1997, the Company's cash flows from
operating activities and the Company's initial public offering have been
sufficient to fund substantially all of the Company's cash requirements. Over
this three-year period, the Company generated cash-based earnings (net income
plus depreciation and amortization) of $53.9 million. This operating cash, along
with the proceeds from the initial public offering of $53.7 million, was
utilized to purchase property, plant and equipment of $42.0 million, intangible
assets of $8.8 million as part of the settlement of the U.K. Litigation, and
short and long-term investments of $19.1 million and to effect net repayment of
long-term debt of $19.4 million.
 
     Net cash provided by operating activities was $9.5 million, $12.7 million
and $31.6 million in 1995, 1996 and 1997, respectively, representing net income
of $8.8 million, $10.2 million and $20.6 million, respectively, adjusted
primarily for depreciation and amortization of $2.6 million, $4.9 million and
$6.9 million, respectively, and in 1997 a tax benefit of $7.9 million from a
gain related to an employee stock option exercise, offset by increases in
accounts receivables and inventory.
 
     Net cash used in investing activities in 1995, 1996 and 1997 was $15.9
million, $11.5 million and $42.5 million, respectively. In 1995 and 1996,
substantially all of this net cash was used to purchase property and equipment.
In 1997, the Company in addition to using $8.8 million to purchase intangible
assets as part of the settlement of the U.K. Litigation and $19.1 million to
purchase short and long-term investments. The $31.0 million increase from 1996
to 1997 in net cash used in investing activities was due primarily to the
settlement of the U.K. Litigation and to the purchase of short and long-term
investments using proceeds from the Company's initial public offering.
 
                                       32
<PAGE>   34
 
     Net cash used in financing activities in 1995 and 1996 was $217,000 and
$316,000, respectively. In each of these years, net cash was used primarily for
repayments of long-term debt. Net cash provided by financing activities in 1997
was $35.2 million, due primarily to net proceeds to the Company from its August
1997 initial public offering of $53.7 million, partially offset by net
repayments of long-term debt of $18.9 million.
 
     In addition to cash, cash equivalents, short-term investments and long-term
investments, the Company has a credit facility with Comerica Bank -- California.
Under the Comerica Credit Agreement, the Company and its subsidiary Ocular
Sciences Puerto Rico, Inc. ("Ocular Sciences Puerto Rico") can borrow up to an
aggregate of $30.0 million. The Comerica Credit Agreement provides for up to $20
million of revolving credit loans to the Company and up to $10 million of term
loans to Ocular Sciences Puerto Rico. Revolving credit borrowings under the
Comerica Credit Agreement bear interest at the bank's base rate or at 1.00% to
1.50% above the eurodollar rate, and term loans bear interest at the bank's base
or at 1.25% to 1.75% above the eurodollar rate, in each case with the applicable
margin over the eurodollar rate depending on the Company's ratio of debt to
tangible net worth. As of December 31, 1997, there were no revolving credit
loans outstanding under the Comerica Credit Agreement. $2.4 million of term
loans were borrowed on November 7, 1997 and used to repay outstanding loans from
the Banco Bilbao de Vizcaya, and the remaining $7.6 million of term loans will
be available to finance the construction and development of the Company's
planned new Puerto Rican manufacturing facility. The revolving credit loans will
be available through June 30, 2000 and the term loan facility provides for
advances through April 30, 1999, at which time the principal amount outstanding
will become payable over twenty-two quarterly principal installments, with a
final maturity date of October 31, 2004. The Company is required to maintain
minimum ratios of debt to tangible net worth and of current assets to current
liabilities, and a minimum tangible net worth. Borrowings under the Comerica
Credit Agreement are secured by a pledge of 100% of the outstanding common stock
of Ocular Sciences Puerto Rico and 65% of the outstanding capital stock of the
Company's United Kingdom and Canadian subsidiaries. In addition, the Company and
Ocular Sciences Puerto Rico have each guaranteed the other's borrowings under
the Comerica Credit Agreement. See Note 7 of Notes to Consolidated Financial
Statements.
 
     The Company is obligated to make minimum base payments on noncancelable
operating leases of $2.5 million, $2.5 million and $1.6 million in 1998, 1999
and 2000, respectively, and has existing commitments to make capital
expenditures of $8.6 million. The Company currently expects to make capital
expenditures of approximately $45.0 million in 1998 (including the $8.6
million), primarily related to the development and implementation of automated
production lines at its manufacturing facilities and the development and
construction of a new Puerto Rican manufacturing facility. However, the amount
of capital expenditures may increase or decrease, as the Company may accelerate
or delay the implementation of the automated production lines based on market
conditions and demand for its products. See "Risk Factors -- Manufacturing
Capacity Constraints; Risks Associated With Expansion and Automation of
Manufacturing Operations."
 
     The Company is in the process of replacing its information systems with new
systems that function properly with respect to dates in the year 2000 and
thereafter. The Company has implemented several of these applications and
anticipates implementing the other planned applications by the end of 1999.
Delays in implementing the new systems could require additional expenditures,
estimated at approximately $500,000, to modify or replace portions of its
existing information systems so that they will function properly with respect to
dates in the year 2000 and thereafter. See "Risk Factors" -- Uncertain Ability
to Manage Growth; Risks Associated with Implementation of New Management
Information Systems.
 
     The Company believes that its current cash and cash equivalents, 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 further credit facilities. 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 marketed
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. These strategies
provide 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 offered by competing distribution 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 annual replacement segment of the United States market with a
market share estimated at approximately 24% in the fourth quarter of 1997, based
on unit sales. Since its introduction of lenses marketed for weekly disposable
replacement regimens in 1993, the Company has steadily increased its share of
this growing market, reaching approximately 12% of total unit sales in the
United States during the fourth quarter of 1997, 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 69% from 1993 to 1997, primarily
due to increased sales of its lenses marketed for weekly disposable replacement
regimens. During the same period, while the overall average selling prices of
all of the Company's lenses declined approximately 59%, the Company reduced its
per unit production costs by approximately 73% 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 1993 to
1997, the Company's net sales and operating income have increased at compound
annual growth rates of approximately 33% and 80%, respectively, while its
operating margins have improved from 7.5% to 25.2% (in each case excluding
non-recurring charges in 1993).
 
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
 
                                       34
<PAGE>   36
 
protein accumulation. Even with this cleaning program, these lenses often became
progressively less 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 marketed 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
marketed for disposable replacement regimens are often made from the same or
similar polymers and can have the same or similar designs as lenses marketed 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 28% from 1987 through 1997,
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 marketed 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 U.S. have 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 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
 
                                       35
<PAGE>   37
 
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 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 offered by competing distribution 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
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 marketed 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 unit shipped for
     disposable replacement regimens, the Company can identify 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 Brand Segmentation by Channel. The high-volume use of lenses
     marketed 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 marketed 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
 
                                       36
<PAGE>   38
 
     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, as well as new, contact lens wearers.
 
          Emphasize Low-Cost Efficient Manufacturing. With the growth of the
     high-volume disposable market segment, lowcost, scaleable manufacturing has
     become increasingly important. The Company's dry cast molding technology
     allows it to manufacture high-quality lenses efficiently. As a result, the
     Company has been able to reduce its per unit production costs by
     approximately 73% over the last four years while increasing its production
     volumes by approximately 876%. The Company plans to implement highly
     automated production lines in its U.K. manufacturing facility beginning in
     the second quarter of 1998, and plans relocate its Puerto Rican
     manufacturing operations to a substantially larger new facility, which will
     also include these highly automated production lines, in 1999. The Company
     believes that the increased unit volumes resulting from the growing
     disposable replacement market and this 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 continues to invest 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 lenses marketed for
     disposable replacement regimens in developed markets such as Europe, Japan
     and Canada and by increased disposable income in emerging markets in 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 Zeiss in Europe and
     Seiko in Japan, to capitalize on their existing market presence, customer
     relationships and local infrastructure. The Company anticipates that Seiko
     will receive initial approval to sell certain of the Company's contact
     lenses marketed for disposable replacement regimens in Japan by the fourth
     quarter of 1998. The Company has also established distribution
     relationships with other soft contact lens distributors in a number of
     countries in the Asian market. 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 superior performance 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
 
                                       37
<PAGE>   39
 
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, 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.
 
     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
marketed for different replacement regimens, many of the Company's lenses
marketed 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 marketed 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 lenses are untinted. The
Company's lenses marketed 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 75.9% of
the Company's net sales in 1997. 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 marketed 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 marketed 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 marketed for weekly replacement regimens
     have demonstrated strong market acceptance, gaining U.S. market share
     steadily since their introduction and representing approximately 12% of
     total unit sales in the growing weekly disposable market segment in the
     United States in the fourth quarter of 1997. The Company sells its lenses
     marketed for weekly disposal 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's lenses marketed for monthly replacement regimens are sold
     primarily under the Hydron ProActive 55, Edge III ProActive
 
                                       38
<PAGE>   40
 
     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 to be marketed 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 lenses marketed for daily disposal is still uncertain.
     Certain of the Company's competitors, including Johnson & Johnson and, more
     recently, Ciba-Geigy and Bausch & Lomb, have introduced, and certain others
     plan to introduce, lower-priced lenses marketed for daily replacement. The
     Company intends to evaluate the market response to their offerings before
     introducing its own lens marketed for daily disposal 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 Replacement Regimens
 
     The Company is a leading provider of soft lenses marketed for annual
replacement regimens in the United States. Lenses marketed for annual
replacement regimens accounted for 21.8% of the Company's net sales in 1997.
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 lenses
for annual replacement regimens 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 marketed for annual replacement regimens in
single-lens vials or blister packs.
 
     Specialty Lenses
 
     Specialty lenses accounted for 2.3% of the Company's net sales in 1997.
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. 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 51-person inside sales force (as of December 31, 1997),
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.
 
                                       39
<PAGE>   41
 
     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 ophthalmologists. 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 1997, sales through
distributors represented approximately 12% 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 marketed 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 lenses marketed
for disposable replacement regimens 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 1997, the Company sold its products to approximately 14,000 independent
practitioner accounts and approximately 85 retail chains. The Company's
customers in each of the past three years have included at least 18 of the top
20 United States optical retailers. Twelve 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 1997, and
the Company's ten largest customers in 1997 represented approximately 22% of the
Company's net sales in that year.
 
     Product Branding. The Company has developed many different trademarked
brands for its lenses marketed 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 lenses marketed for disposable
replacement regimens 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 lenses in developed
markets such as Europe, Japan and Canada and by increased disposable income in
emerging markets in 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 15 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 Zeiss. In this relationship, Zeiss
     sells the Company's contact lenses marketed for disposable replacement
     regimens 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 marketed 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.
 
          Asia. The Company believes that the growth of unit sales in this
     market will be driven primarily by sales of contact lenses marketed for
     disposable replacement regimens, particularly in Japan. Unit sales of
     lenses marketed 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
 
                                       41
<PAGE>   43
 
     relationship with Seiko, which is responsible for obtaining local
     regulatory approvals and will distribute the Company's lenses to Japanese
     eyecare practitioners through its network of approximately 69 direct sales
     representatives. The Company anticipates that Seiko will receive initial
     approval to sell certain of the Company's contact lenses marketed for
     disposable replacement regimens in Japan by the fourth quarter of 1998. 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; Romsey, 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
Romsey, 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 1997, an
average of approximately 2,596 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 reduce its cost-to-serve and improve customer service, the
Company has recently implemented a highly computerized and automated retrieval
system at its South San Francisco facility. This system incorporates advanced
handling processes such as automatic dispensing, automated conveyors and radio
frequency dispatch. These processes are 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. The Company intends to implement a similar system in the United
Kingdom.
 
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 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
 
                                       42
<PAGE>   44
 
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.
 
     The Company believes that dry cast molding is a highly scaleable process,
which makes it well suited to address the high-volume requirements of the
growing disposable replacement market. Using this technology, the Company has
been able to increase production volumes by approximately 876% from 1993 to
1997. The disposable replacement market, however, is relatively price-sensitive,
and lenses marketed for disposable replacement regimens generally have
significantly lower selling prices than lenses marketed 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 is assembling and testing much of the
equipment necessary, for the first of the planned new production lines, to be
installed at its United Kingdom facility. The Company anticipates commencing
initial production this line in the second quarter of 1998, and believes that a
year may be required before the new line can operate at anticipated yields and
production levels. The Company anticipates installing additional automated lines
in both the United Kingdom and Puerto Rico. The Company believes that, as the
new automated lines are implemented and their production volumes increased, they
will 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. The Company
currently expects that from 1998 through the end of 2000, it will invest
approximately $64.0 million in capital expenditures on these automated
production lines, and the Company expects to continue to invest in additional
automated production lines after this period. 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 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 quality system (including
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. See "Risk Factors -- Manufacturing Capacity
Constraints; Risks of Expansion and Automation of Manufacturing Operations" and
"-- Risks Associated with Interruption of Manufacturing Operations."

INFORMATION SYSTEMS
 
     The Company believes that its information systems are an integral component
of its strategy to minimize its cost-to-serve and improve customer service. The
Company is in the process of replacing its information systems with new systems
that are expected to include a number of integrated applications, including
order entry, billing and labeling. The new systems will significantly affect
many aspects of the Company's business, including its manufacturing, sales and
marketing, distribution and accounting functions, and the successful
implementation and integration of these applications will be important to
facilitate future growth. Applications for forecasting and demand management
were implemented in the fourth quarter of 1997, and the Company anticipates
implementing applications providing the remaining planned functions by the end
of 1999. However, the Company could experience unanticipated delays in the
implementation of the new systems and implementation of the new information
systems could cause significant disruption in operations. See "Risk
Factors -- Uncertain Ability to Manage Growth; Risks Associated with New
Management Information Systems."
 
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 currently operating at or near capacity (based on a single
production shift per work day.) 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 to the
Company's specifications and leased to the Company by the Puerto Rico Industrial
Development Company. The Company has entered into a letter of intent and is
negotiating the final terms of the lease for this facility. The Company began
construction of the new facility during the first quarter of 1998 and expects to
complete construction, and initial installation of equipment, by the second
quarter of 1999. Until the new Puerto Rican facility is completed, the Company
intends to utilize excess capacity in the United Kingdom, or increase capacity
in Puerto Rico through additional production shifts, to meet any requirements
for increased volumes of lens production. See "-- Manufacturing" and "Risk
Factors-- Manufacturing Capacity Constraints; Risks Associated with Expansion
and Automation of Manufacturing Operations."

    building is owned by the Company.
 
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 is developing
lenses that absorb ultraviolet light and is evaluating the introduction of
lenses marketed for daily disposable replacement regimens. See "-- Government
Regulation." During the years ended December 31, 1995, 1996 and 1997,
expenditures for research and development (including obtaining regulatory
approvals) were approximately $1.0 million, $1.1 million and $2.4 million,
respectively. See "Risk Factors -- Risk of New Products and Technological
Change."
 
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
 
                                       45
<PAGE>   47
 
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, who were significant
stockholders of the Company prior to its initial public offering and adverse
parties to the U.K. Litigation, 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 "Risk Factors -- Intense Competition" and "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 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. As the number of wearers
of soft contact lenses in the U.S. has not grown significantly in recent years,
increased U.S. market penetration by the Company will require wearers of
competing products to switch to the Company's products. The Company's products
compete with products offered by a number of larger companies including Johnson
& Johnson, Ciba-Geigy, Bausch & Lomb, Wesley Jessen and Cooper. Many 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
 
                                       46
<PAGE>   48
 
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 "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 marketed for disposable replacement regimens, where
the Company is less experienced and has a significantly smaller market share.
The disposable replacement market 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 replacement market 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 replacement market are marketed
for weekly and monthly replacement regimens. Certain of the Company's
competitors have introduced lenses marketed for daily replacement at lower
prices than their lenses currently marketed for weekly and bi-weekly disposal.
Recently, Ciba-Geigy has introduced a lower-priced lens marketed for daily
replacement in the U.S. market, and Bausch & Lomb has begun selling lenses
marketed for daily replacement in certain European markets. The Company is
evaluating the introduction of a lens marketed for daily disposal regimens. 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 marketed for different replacement regimens are often similar,
the ability of competitors to reduce their per unit costs for lenses marketed
for daily disposal 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 affect the Company's ability to compete
in marketing lenses for a much broader range of replacement regimens. See "Risk
Factors -- Dependence on Single Product Line; Need to Increase Sales of Lenses
for Disposable Replacement Regimens."
 
     In December 1997, Cooper acquired AVCL, a U.K.-based manufacturer and
marketer of soft contact lenses. AVCL's manufacturing process technology and
lens designs are based in part on technology also licensed to, and used by, the
Company. AVCL was, until recently, contractually prohibited from selling lenses
in the United States. See "Certain Transactions -- OSL Acquisition and Related
Litigation." Cooper has recently announced that it has introduced a new line of
contact lenses marketed in the United States for
 
                                       47
<PAGE>   49
 
weekly and monthly replacement regimens that utilize AVCL's manufacturing
process technology and lens designs, and that this new line will provide
practitioners with products that are proprietary to their practice.
 
     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 "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
by the FDA, exempted from the requirement of FDA clearance, or approved by the
FDA 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 and adherence to FDA-mandated quality system (including
current GMP) requirements and, in some cases, 510(k) notification), and Class II
devices are subject to general controls including, in most cases, 510(k)
notification 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 requires 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
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
 
                                       48
<PAGE>   50
 
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 necessary clinical trials are 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 twentyfour months, and can take substantially longer.
 
     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 quality system (including current 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
 
                                       49
<PAGE>   51
 
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.
 
     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 quality system ("QS") regulation,
which includes, among other things, the FDA's GMP requirements. This regulation
requires, 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 regulation
also requires (i) investigation of any deficiencies in the manufacturing process
or in the products produced, (ii) purchasing controls, (iii) detailed
record-keeping including the maintenance of service records and (iv)
pre-production design controls. Manufacturing facilities are subject to FDA
inspection on a periodic basis to monitor compliance with QS (including current
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. The pre-production design control requirements 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. The Company
believes that its facilities are in compliance with the FDA's QS regulations and
that the planned automation of its manufacturing facilities will not require
clearance or approval.
 
     The Company is also required to register as a medical device manufacturer
and to list its products 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 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
 
                                       51
<PAGE>   53
 
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. 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 500,000 Canadian dollars 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 continue to
receive, complaints of significant patient discomfort, including corneal
scarring and 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 $20.0 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 December 31, 1997, the Company had 1,167 full-time employees,
including 297 in the United States, 373 in the United Kingdom, 460 in Puerto
Rico, 27 in Canada and 10 in Hungary. Of the Company's full-time employees, 119
are engaged in sales and marketing, 749 in manufacturing, 198 in distribution,
eight in process development and 93 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
Chief Executive Officer, 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."

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
 
                                       54
<PAGE>   56
 
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
 
     Prior to the Company's initial public offering, the non-employee members of
the Board were issued shares of the Company's Common Stock as compensation for
their 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 services during 1996. In
November 1997, the Company paid $4,333 to each of Messrs. Grant, Fruth, Cummins
and Tunney as compensation for services in 1997. Members of the Board are also
reimbursed for their reasonable expenses in attending meetings of the Board.
 
     In June 1997, the Board adopted and the stockholders approved 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 August 4, 1997, the effective date of the
Company's initial public offering, each eligible director was granted an option
to purchase 30,000 shares. Each eligible director who hereafter becomes a member
of the Board 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. As of December 31, 1997,
options to purchase a total of 120,000 shares of Common Stock has been granted
under the Directors Plan. All options granted under the Directors Plan vest as
to 1/36 of the shares subject to the option per month commencing the month
following the month of 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 is and 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 Amended
and Restated 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

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

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

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.

EMPLOYMENT AGREEMENTS
 
     In October 1997, Norwick B.H. Goodspeed joined the Company as its President
and Chief Operating Officer pursuant to the terms of an employment agreement
dated October 15, 1997. Under the employment agreement, the Company agreed to
employ Mr. Goodspeed as its President and Chief Operating Officer at an initial
annual base salary of $300,000. Mr. Goodspeed is eligible to receive a bonus of
up to 60% of his annual
 
                                       56
<PAGE>   58
 
salary in 1998, and up to 50% of his annual salary for each year thereafter. In
addition, Mr. Goodspeed has received an option to purchase 300,000 shares of the
Company's Common Stock at an exercise price of $24.25 per share, vesting 20% per
year over five years so long as Mr. Goodspeed is employed by the Company. The
Company has also agreed to pay certain relocation costs and other costs
associated with the sale of Mr. Goodspeed's prior residence in southern
California, up to a maximum of $159,000. To date, the Company has paid $80,000
of such relocation costs. The employment agreement further provides that Mr.
Goodspeed's employment will continue for a term of three years unless and until
terminated by either the Company or Mr. Goodspeed.
 
     Under Mr. Goodspeed's employment agreement, the Company extended a $450,000
loan to Mr. Goodspeed in January 1998 in connection with his purchase of a new
residence in the San Francisco area (the "Loan"). The Loan is interest free and
is secured by a purchase money second deed of trust on the new residence and by
a security interest in certain stock options granted to Mr. Goodspeed to
purchase 300,000 shares of the Company's Common Stock and any securities
issuable upon exercise of such options. The Loan is due and payable in full on
the earlier of (i) October 15, 2002; (ii) six months after Mr. Goodspeed's
voluntary resignation or termination by the Company for Cause (as defined in Mr.
Goodspeed's employment agreement); or (iii) Mr. Goodspeed's agreement to sell,
convey, transfer, dispose of, or further encumber the new residence. Under the
terms of the employment agreement, the Company has agreed to forgive the Loan in
its entirety (and return any payments received in connection therewith), in the
event that Mr. Goodspeed remains continuously employed with the Company from
October 15, 1997 through October 15, 2000. The Company has also agreed to
forgive 50% of the Loan in the event that Mr. Goodspeed is terminated by the
Company by written notice without cause.
 
     Pursuant to the terms of an employment agreement dated March 1996, the
Company employed Dr. John Lilley as its Vice President, Manufacturing at an
initial annual salary of L95,000. This salary was increased to L103,000 in 1997.
Under the employment agreement, Dr. Lilley is eligible to receive a bonus of up
to 40% of his annual salary at the discretion of the Company based on the
achievement of manufacturing goals and objectives established by the Company at
the start of each fiscal year. In 1996, Dr. Lilley also received an option to
purchase 80,000 shares of the Company's Common Stock at an exercise price of
$5.03 per share. Under Dr. Lilley's employment agreement, his employment will
continue unless and until either the Company or Dr. Lilley serves on the other
12 months' notice of termination, provided that the Company has the right to
terminate his employment upon his 65th birthday.
 
                             OPTION GRANTS IN 1997
 
     The following table sets forth information regarding option grants during
1997 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
respective six-year terms. These gains are based on assumed rates of annual
compound stock price appreciation of 5% and 10% from the date the option was
granted to the end of the option term.

EMPLOYEE BENEFIT PLANS
 
     1989 Stock Option Plan. Under the 1989 Plan, options to purchase 1,756,454
shares of Common Stock were outstanding as of December 31, 1997. The 1989 Plan
was terminated on August 4, 1997, the effective date of the Company's initial
public offering, at which time the Company's 1997 Equity Incentive Plan became
effective. As a result, no options have been granted under the 1989 Plan since
the Company's initial public offering. However, termination does not 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.
 
     1997 Equity Incentive Plan. In June 1997, the Board adopted and the
stockholders approved the 1997 Plan, under which 2,290,694 shares of Common
Stock are reserved for issuance. As of February 15 1998, options to purchase
1,618,500 shares of the Company's Common Stock have been granted under the 1997
Plan. The 1997 Plan will terminate in May 2007, unless sooner terminated by the
Board. The 1997 Plan authorizes the award of options, opportunities to purchase
restricted stock and stock bonuses (each an "Award"). The 1997 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 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 Plan.
 
                                       58
<PAGE>   60
 
     The 1997 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 Plan is ten
years. Options granted under the 1997 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 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 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 has yet to become effective, and as of
December 31, 1997 no shares of Common Stock had been purchased under the
Purchase Plan. If and when the Purchase Plan becomes effective, it 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, 1995, 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 and related loans, which are described
under the caption "Management-Employment Agreements," 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 Chief Executive Officer 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"), who received 1,015,024 shares of the Company's Common Stock in the
acquisition. Prior to this acquisition, Geoffrey H. Galley had owned 190,400
shares of the Company's Common Stock.
 
     In connection with the PLL Acquisition, PLL entered into a patent license
agreement (the "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. 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 14 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.
 
                                       60
<PAGE>   62
 
     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 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, and (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. The Settlement Agreement also provided for the payment of $10
million by the Company, of which $3.3 million was paid on the date of the
Settlement Agreement and the remaining $6.7 million was paid upon the closing of
the Company's initial public offering. See Note 16 of Notes to Consolidated
Financial Statements.
 
     The Patent Owners sold all of the shares of Common Stock owned by them in
the Company's initial public offering, and have agreed not to acquire additional
shares of the Company's Common Stock or other securities or assets of the
Company for a period of five years from the date of the Company's initial public
offering. In December 1997, AVCL was acquired by Cooper. See "Risk
Factors -- Intense Competition."
 
ALLERGAN/AMERICAN HYDRON ACQUISITION; GALEN FINANCING
 
     In October 1992, the Company acquired the North and South American contact
lens business of Allergan, which had been operating under the name American
Hydron, for $24.5 million, including acquisition costs of $1.2 million. The
transaction 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 with bank borrowings in 1993 and the senior subordinated notes were
repaid with 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. On December 31, 1996, the remaining warrants were
canceled pursuant to their terms because the Company had met certain financial
milestones. The Series A Preferred Stock was converted into 236,336 shares of
Common Stock at the consummation of the Company's initial public offering.
 
     In connection with the American Hydron acquisition, the Company 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 Chief Executive Officer of the
Company, is a partner, has provided legal services to the Company since its
formation. The Company made payments of $309,000 in 1995, $284,000 in 1996 and
$77,000 in 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
$2.9 million junior subordinated promissory note, bearing interest at the prime
rate plus 3%. The Company repaid the note with a portion of the net proceeds
from the Company's initial public offering.

                          DESCRIPTION OF CAPITAL STOCK
 
     The authorized capital stock of the Company consists 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 February 15, 1998, there were outstanding 21,867,816 shares
of Common Stock held of record by 92 stockholders, and options to purchase
3,364,944 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
 
     Pursuant to the Company's Amended and Restated 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
 
     The holders of approximately 8,266,358 shares of Common Stock following
this offering (the "Registrable Securities") have certain rights to register
those shares under the Securities Act. If requested by the holders of at least
10% of the Registrable Securities, the Company must file a registration
statement under the Securities Act covering all Registrable Securities requested
to be included by all holders of such Registrable Securities, provided such
offering represents at least 20% of the Registrable Securities then outstanding.
These demand registration 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 two such registrations (in addition to
this offering, which constitutes such a demand registration), 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.
 
     In addition, if the Company proposes to register any of its securities
under the Securities Act, whether or not for sale for its own account, other
than in connection with a Company employee benefit plan or a corporate
 
                                       65
<PAGE>   67
 
reorganization, the holders of Registrable Securities are entitled to notice of
such registration and are entitled to include shares of such Common Stock
therein. 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. All expenses incurred in
connection with such registrations (other than underwriters' discounts and
commissions) will be borne by the Company. These registration rights expire
October 30, 2002.
 
TRANSFER AGENT AND REGISTRAR
 
     The Transfer Agent and Registrar for the Company's Common Stock is American

DELAWARE TAKEOVER STATUTE
 
     The Company is subject to Section 203 of the Delaware General Corporation
Law ("Section 203"), which, subject to certain exceptions, prohibits a Delaware
corporation from engaging in any business combination with any interested
stockholder for a period of three years following the time that such stockholder
became an interested stockholder, unless: (i) prior to such time, the board of
directors of the corporation approved either the business combination or the
transaction that resulted in the stockholder's becoming an interested
stockholder; (ii) upon consummation of the transaction that resulted in the
stockholder's becoming an interested stockholder, the interested stockholder
owned at least 85% of the voting stock of the corporation outstanding at the
time the transaction commenced, excluding, for purposes of determining the
number of shares outstanding, those shares owned (x) by persons who are
directors and also officers and (y) by employee stock plans in which employee
participants do not have the right to determine confidentially whether shares
held subject to the plan will be tendered in a tender or exchange offer; or
(iii) at or subsequent to such time, the business combination is approved by the
board of directors and authorized at an annual or special meeting of
stockholders, and not by written consent, by the affirmative vote of at least
two-thirds of the outstanding voting stock that is not owned by the interested
stockholder.
 
     Section 203 defines business combination to include: (i) any merger or
consolidation involving the corporation and the interested stockholder or any
other partnership, incorporated association or other entity if the merger is
caused by the interested stockholder; (ii) any sale, lease, exchange, mortgage,
transfer, pledge or other disposition involving the interested stockholder of
10% or more of the aggregate market value of the assets of the corporation or of
the outstanding stock of the corporation; (iii) subject to certain exceptions,
any transaction that results in the issuance or transfer by the corporation of
any stock of the corporation to the interested stockholder; (iv) any transaction
involving the corporation which has the effect of increasing the proportional
share of capital stock or securities convertible into capital stock of the
corporation which is owned by the interested stockholder, except for certain
immaterial adjustments; or (v) the receipt by the interested stockholder of the
benefit of any loans, advances, guarantees, pledges or other financial benefits
provided by or through the corporation (except those permitted by (i)-(iv)
above). In general, Section 203 defines an interested stockholder as any entity
or person beneficially owning 15% or more of the outstanding voting stock of the
corporation and any entity or person affiliated with or controlling or
controlled by such entity or person. See "Risk Factors -- Certain Anti-Takeover
Provisions."

are held by "affiliates" of the Company as that term is defined in Rule 144
under the Securities Act. The remaining 9,408,774 shares of Common Stock
("Restricted Shares") may be sold in the public market only if registered or if
they qualify for an exemption from registration under Rule 144 promulgated under
the Securities Act, which is summarized below.
 
     After giving effect to this offering, an aggregate of
               Restricted Shares will be held by "affiliates". All of such
shares are subject to contractual lock-ups in which the holders have agreed not
to sell or otherwise dispose of such shares for 90 days after the date of this
Prospectus without the prior consent of Morgan Stanley & Co., Incorporated, and,
subject to such lock-ups and to the volume and manner of sale restrictions of
Rule 144, such shares will be eligible for public resale following this
offering. All of the Restricted Shares were subject to contractual lock-ups
entered into in connection with the Company's initial public offering, which
lock-ups expired on February 1, 1998. An additional        Restricted Shares not
held by affiliates may be sold in the public market after this offering subject
to the volume and resale restrictions of Rule 144. The remaining
Restricted Shares are "144(k) Shares" or "Rule 701 Shares" and will be eligible
for public sale following this offering and will not be subject to any volume
restrictions, holding periods or contractual lock-ups. Sales of a substantial
number of Restricted Shares in the public market 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, 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 218,978 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, notice requirements and the availability of current public
information about the Company.
 
     Shares of Common Stock issued upon exercise of options will be available
for sale in the public market, subject to Rule 144 volume limitations applicable
to affiliates, and subject to lock-up agreements with respect to executive
officers and directors of the Company. At February 15, 1998, options to purchase
3,364,944 shares of Common Stock were outstanding, of which options to purchase
765,922 shares were vested and exercisable. Of such vested and exercisable
options, options to purchase 602,778 shares were held by affiliates and will be
subject to 90-day lock-up agreements, and the remaining 163,144 shares issuable
under vested options may be sold in the public market without restriction upon
exercise of such options. 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 initially 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 public offering price. Any
Underwriter may allow, and such dealers may re-allow, a concession not in excess
of $     per share to other Underwriters or to certain other dealers.
 
     Pursuant to the Underwriting Agreement, John D. Fruth, one of the Selling
Stockholders and the Company's Chief Executive Officer, has granted to the
Underwriters an option, exercisable for 30 days from the date of this
Prospectus, to purchase up to 604,500 additional shares of Common Stock at the
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 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 executive officers and directors, and certain other
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
90 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 90 days after the date of this Prospectus, except under certain
circumstances.

     Morgan Stanley & Co. Incorporated, Bear, Stearns & Co. Inc. and Cowen &
Company were the representatives of the several underwriters in the Company's
initial public offering of 8,280,000 shares of the Company's Common Stock
(including 1,080,000 shares sold to cover overallotments) in August 1997, for
which they received customary underwriting discounts and commissions.
 
     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 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 and dealers may engage
in passive market making transactions in the Common Stock in accordance with
Rule 103 of Regulation M promulgated by the Commission. In general, a passive
market maker may not bid for, or purchase, the Common Stock at a price that
exceeds the highest independent bid. In addition, the net daily purchases made
by any passive market maker generally may not exceed 30% of its average daily
trading volume in the Common Stock during a specified two month prior period, or
200 shares, whichever is greater. A passive market maker must identify passive
market making bids as such on the Nasdaq electronic inter-dealer reporting
system. Passive market making may stabilize or maintain the market price of the
Common Stock above independent market levels. Underwriters and dealers are not
required to engage in passive market making and may end passive market making
activities at any time.
 
                                 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, 1996 and 1997, 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, 1997. 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, 1996 and 1997, and the
results of their operations and their cash flows for each of the years in the
three-year period ended December 31, 1997, in conformity with generally accepted
accounting principles.

                  YEARS ENDED DECEMBER 31, 1995, 1996 AND 1997
 
NOTE 1. NATURE OF BUSINESS
 
FORMATION AND BUSINESS OF THE COMPANY
 
     O.S.I. Corporation was incorporated in California in 1985. On July 31,
1997, the Company effected a reincorporation into the state of Delaware and
changed its name to Ocular Sciences, Inc. The Company is engaged in the design,
manufacture and distribution of contact lenses and conducts business under the
name of Ocular Sciences/American Hydron.
 
THE INITIAL PUBLIC OFFERING (THE "IPO")
 
     On August 8, 1997, the Company closed its initial public offering of
8,280,000 shares of its Common Stock at an initial public offering price of
$16.50 per share. Of the 8,280,000 shares, 3,600,000 shares were sold by the
Company and the remaining 4,680,000 were sold by certain selling shareholders.
The net proceeds to the Company were $53.7 million, after deducting underwriting
discounts and commissions and other offering expenses payable by the Company.
The Company utilized $11.6 million of the proceeds to repay all of the debt
outstanding under the Company's Credit Agreement with Comerica
Bank -- California, $2.9 million of the proceeds to repay subordinated debt owed
to the Company's Chief Executive Officer, $6.7 million of the proceeds as final
payment pursuant to the settlement agreement of certain U.K. litigation (Note
16) and $400,000 for the construction of the new Puerto Rican manufacturing
facility.
 
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.), Ocular Sciences Puerto Rico
Corporation, Ocular Sciences 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
 
     Cash equivalents consist of commercial paper, money market funds, United
States government debt securities and certificates of deposits with original
maturities of three months or less.
 
  Financial Instruments
 
     All of the Company's short-term and long-term investments are classified as
"available-for-sale" under the provisions of Statement of Financial Accounting
Standards ("SFAS") No. 115, "Accounting for Certain Investments in Debt and
Equity Securities."
 
     The amortized costs of available-for-sale debt securities are adjusted for
amortization of premiums and accretion of discounts to maturity. Such
amortization is included in net investment income. As required by SFAS No. 115,
available-for-sale debt securities are recorded at fair value. Unrealized gains
and losses, net of tax, are reported as a separate component of stockholders'
equity. Realized gains and losses, and declines in value judged to be other than
temporary on available-for-sale securities, are included in other (expense)

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
                  YEARS ENDED DECEMBER 31, 1995, 1996 AND 1997
 
income, net. The cost of securities sold is based on the specific identification
method. Interest and dividends on securities classified as available-for-sale
are included in interest income.
 
     The Company's short-term and long-term investments in marketable equity
securities are carried at fair value, based on quoted market prices for these or
similar investments.
 
     The carrying amounts reported in the balance sheet for cash, receivables,
related party loans, accounts payable, accrued liabilities and short-term and
long-term debt approximate fair values due to their short maturities.
 
  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, 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 14 and 16). The restricted cash
balance as of December 31, 1997 related to cash held in escrow for the Company's
United Kingdom leased facility.
 
  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 and discounts 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 lenses marketed for disposable replacement
regimens. The Company records the provisions for cooperative merchandising at
the time of sale to the customers and as a component of selling and marketing
expenses.
 
  Foreign Currencies
 
     The functional currencies of the Company's United Kingdom, Canadian and
Hungarian subsidiaries are the respective local currencies. Accordingly, 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
consolidated 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 accounts receivable is limited
due to the large number and diversity of customers across broad geographic
areas. Accounts

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
                  YEARS ENDED DECEMBER 31, 1995, 1996 AND 1997
 
receivable from customers are uncollateralized. As of December 31, 1996,
approximately 22% of accounts receivable and 12% of consolidated net sales were
concentrated in two customers, while, as of December 31, 1997, approximately 16%
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.
 
  Long-Lived Assets, Including Intangible Assets
 
     The Company accounts for long-lived assets under SFAS No. 121, "Accounting
for Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed
of." SFAS No. 121 requires that long-lived assets and certain identifiable
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 loss 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. The Company estimates fair value based on the best information available,
making judgments and projections as considered necessary.
 
     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.
 
     Under this approach, deferred income taxes reflect the tax consequences 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.
 
  Net Income Per Share
 
     The Company adopted SFAS No. 128, "Earnings per Share," as of December 31,
1997. SFAS No. 128 establishes standards for computing and presenting earnings
per share. Net income per share (basic) is computed based on the weighted
average number of common shares outstanding, and net income per share (diluted)
is computed based on the weighted average number of common shares and dilutive
potential

                  YEARS ENDED DECEMBER 31, 1995, 1996 AND 1997
 
common shares outstanding during the period. Dilutive potential common shares
include the conversion of stock options using the treasury stock method. The
August 8, 1997 conversion of the shares of Series A Preferred Stock into 236,336
shares of common stock is included in the weighted average dilutive potential
common shares outstanding figures for all periods presented. In accordance with
Securities and Exchange Commission Staff Accounting Bulletins and staff policy,
net income per share (diluted) includes all common and dilutive potential common
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 initial public offering price. Certain historical net
income per share data has not been presented since such amounts are not deemed
meaningful due to the change in the Company's capital structure that occurred in
connection with the Company's initial public offering. All prior period net
income per share data was restated by the Company upon adoption of SFAS No. 128.
 
  Stock-Based Compensation
 
     The Company follows 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 additional paid-in capital.
 
  New Accounting Standard
 
     In June 1997, the Financial Accounting Standards Board issued SFAS Nos. 130
and 131, "Reporting Comprehensive Income" ("SFAS No. 130") and "Disclosures
about Segments of an Enterprise and Related Information" ("SFAS No. 131"),
respectively ("collectively, the "Statements"). The Statements are effective for
fiscal years beginning after December 15, 1997. SFAS No. 130 establishes
standards for reporting of comprehensive income and its components in annual
financial statements. SFAS No. 131 establishes standards for reporting financial
and descriptive information about an enterprise's operating segments in its
annual financial statements and selected segment information in interim
financial reports. Reclassification or restatement of comparative financial
statements or financial information for earlier periods is required upon
adoption of SFAS No. 130 and SFAS No. 131, respectively. Application of the
Statements' disclosure requirements will have no impact on the Company's
consolidated financial position, results of operations or net income per share
data as currently reported.

     As of December 31, 1997, short-term and long-term investments amounted to
$10,000,000 and $9,070,000, respectively. Short-term and long-term investments

Depreciation and amortization expense on machinery and equipment under long-term
leases was approximately $62,000, $148,000 and $478,000 for the years ended
December 31, 1995, 1996 and 1997.
 
     In the fourth quarter of 1997, the Company finalized plans to change the
packaging component of its manufacturing process to be implemented in late 1998,
which will render certain of the Company's existing manufacturing equipment
obsolete. In accordance with SFAS No. 121, the Company recorded a pretax charge
to cost of sales of $824,000 related to this impairment loss and reduced the
carrying amount of this asset by a corresponding amount. The amount of
impairment loss is the excess of the carrying amount of the impaired asset over
the fair value of the asset.

     In late 1996, the Company executed a commercial lending facility (the
"Agreement") with a major commercial bank. The Agreement provided for a term
loan and 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 was
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 term loan was in the
amount of $10,000,000. The facility was secured by the Company's accounts
receivable, inventory, loans and notes receivable, the stock of the Company's
subsidiaries, and certain intangible assets; provided that the collateral did
not include more than 65% of any class of equity securities of any foreign
subsidiary. The Agreement provided 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 agreement contained a commitment fee of 0.375% per annum on
the unused portion of the revolving line of credit. The Company was also
required under the Agreement to maintain minimum debt to tangible net worth,
interest coverage and tangible net worth ratios, and the Agreement placed
certain limitations on debt, liens, contingent obligations, investments and cash
dividends on common stock. The term loan and the credit facility were paid off,
in full, during 1997.
 
     On November 7, 1997 the Company amended its credit agreement (the "Amended
Credit Agreement") with this same commercial bank. Under the new agreement, the
Company and its subsidiary, Ocular Sciences Puerto Rico, Inc. ("Ocular Sciences
Puerto Rico") can borrow up to an aggregate of $30,000,000. The Amended Credit
Agreement provides for a revolving line of credit of up to $20,000,000 to the
Company and up to $10,000,000 of term loans to Ocular Sciences Puerto Rico.
Under the Amended Credit Agreement the revolving line of credit has two interest
rate options --interest at the bank's base rate or at 1.00% to 1.50% above the
rate at which deposits in eurodollars are offered to the bank by other prime
banks in the eurodollar market, with the applicable margin over the eurodollar
rate depending on the Company's ratio of debt to tangible net worth. The Company
pays commitment fees of 0.250% to 0.375% on the revolving line of credit, with
percentages varying based on the Company's ratio of debt to tangible net worth.

revolving line of credit are due in full on June 30, 2000. The Company may elect
to prepay any principal due under the revolving line of credit but would be
required to reimburse the lending bank for any breakage costs with respect to
prepayment of any eurodollar rate loan prior to the end of an applicable
interest period. At December 31, 1997, the Company had no borrowings under the
revolving line of credit and thus the full $20,000,000 remained available.
 
     A term loan, with a December 31, 1997 balance of $2,183,000, was borrowed
on November 7, 1997 under the Amended Credit Agreement and used to repay
outstanding notes payable to Banco Bilbao de Vizcaya, Puerto Rico ("BBV"). The
remainder of the $10,000,000 term loan is available to finance the construction
and development of Ocular Sciences Puerto Rico's new manufacturing facility. The
term loan provides for three interest rate options --interest at the bank's base
rate, interest at 1.25% to 1.75% above the rate at which deposits in eurodollars
are offered to the bank by other prime banks in the eurodollar market, or
interest at 1.25% to 1.75% above the negotiated rate, defined as the lending
bank's cost of funds (after reserve requirements) plus its FDIC insurance rate.
The negotiated rate option is available only after April 30, 1999. The effective
interest rate of the term loan as of December 31, 1997 was 7.1875%. There are no
commitment fees on the term loan. On April 30, 1999, the then-outstanding term
loan will become payable in twenty-two quarterly principal installments
beginning July 31, 1999, $250,000 each quarter with any balance to be paid on
October 31, 2004. The Company may elect to prepay the principal due under the
term loan but would be required to reimburse the lending bank for any breakage
costs with respect to prepayment of any eurodollar rate loan prior to the end of
an applicable interest period.
 
     Borrowings by the Company under the Amended Credit Agreement are guaranteed
by Ocular Sciences Puerto Rico, and borrowings by the Ocular Sciences Puerto
Rico, under the Amended Credit Agreement are guaranteed by the Company.
Borrowings under the Amended Credit Agreement are secured by a pledge of 100% of
the outstanding common stock of Ocular Sciences Puerto Rico and 65% of the
outstanding capital stock of the Company's United Kingdom and Canadian
subsidiaries. The Company is also required under the Amended Credit Agreement to
maintain minimum ratios of debt to tangible net worth and of current assets to
current liabilities, and a minimum tangible net worth, and the Amended Credit
Agreement places certain limitations on debts, liens, contingent obligations,
investments and cash dividends on common stock.
 
     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.
 
     In 1995, the Company guaranteed the borrowings of Ocular Sciences Puerto
Rico, under a loan agreement with BBV for the financing of the construction of
an industrial building at Santa Isabel Industrial Park, Santa Isabel, Puerto
Rico, and for the purchase of machinery and equipment not to exceed the total
sum of $5,800,000. The loan was 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 was payable in December 1997 or upon the closing of a
permanent financing loan from the Government Development Bank of Puerto Rico
("GDB"). The BBV loan bore interest at 2% over the lender's defined cost of
funds or, in the event that such funds were not available, 1.5% over the
lender's prime lending rate. The effective interest rate as of December 31, 1996
was 8%. The BBV loan agreement also contained a commission fee equal to 1% of
the principal and drawing fees equal to 0.5% of the

loan amount. This loan was fully paid by a portion of the term loan under the
Amended Credit Agreement in 1997. As of December 31, 1996, the loan amount
outstanding under this agreement was $1,069,000.
 
     The long-term debt, including current portion, is due in aggregate annual

from 1998 through 2001.

per share, subject to adjustment for dilution. The warrants, by their terms,
expired on the earlier of October 30, 2002 or the date of effectiveness of a

Company repaid this note on October 30, 1996 (see Notes 7 and 14) and achieved
the financial performance goals. As a result, all outstanding warrants were

  Stock-based Compensation Plans
 
     The Company has the following stock-based compensation plans:
 
          (i) 1989 Stock Option Plan
 
          The 1989 Stock Option Plan provided for the grant to employees,
     directors and 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 non-qualified options, exercisable at a price not less than 85% of
     the fair market value of the shares on the date of grant. The options
     generally were granted for a six-year term and vested over a five-year
     period. This plan was terminated upon the effective date of the Company's
     initial public offering on August 4, 1997. Any authorized shares not issued
     or subject to outstanding grants under this plan on August 4, 1997 and any
     shares that are issuable upon exercise of options granted pursuant to this
     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. As of December 31, 1997, options to purchase a
     total of 1,756,454 shares are outstanding under this plan.
 
          (ii) 1992 Officers and Directors Stock Option Plan

     fair market value of the Company's common stock on the grant date. A total
     of 1,280,000 shares of common stock were reserved for issuance under this
     plan. In 1992 the Company's Chief Executive Officer was granted an option
     to purchase the 1,280,000 shares of common stock reserved under this plan.
     This option was exercised, in full, during 1997 at an exercise price of

     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 no less than the fair market value of
     the Company's Common Stock on the date of grant and the exercise price of
     all nonqualified stock options must be at a price not less than 85% of such
     fair market value. The options generally are granted for a ten-year term
     and vest over a five-year period. Any authorized shares not issued or
     subject to outstanding grants under the 1989 Plan on August 4, 1997 and any

     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. The options generally are granted for a ten-year term and
     vest over a three-year period. A total of 300,000 shares of common stock

Company is required to disclose the pro forma effects on net income and net
income per share as if the Company had elected to use the fair value approach to
account for all its employee stock-based compensation plans. Had compensation
cost for the Company's plans been determined in a manner consistent with the
fair value approach enumerated in SFAS No. 123, the Company's pro forma net
income and pro forma net income per share for the years ended December 31, 1996

NOTE 13. 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 additional paid-in capital. Such amounts
approximated $273,000 and $7,869,000 for 1996 and 1997.

     At December 31, 1997, taxes had not been provided on $2,586,000 of
accumulated foreign unremitted earnings, which are expected to remain invested
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.
 
NOTE 14. 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 were stockholders of the
Company prior to the initial public offering. 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 patent owners 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 16).
 
     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 16, AVCL
and the Company were

involved in litigation, which was settled in February 1997. AVCL accounted for
$407,000 of accounts receivable as of December 31, 1996. There were no sales to
AVCL in 1995, 1996 or 1997. A provision was recorded for the full amount of the
accounts receivable from AVCL as of December 31, 1996, which was subsequently
written off during the year ended December 31, 1997.
 
     During 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 16).
 
     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
7).
 
     As of December 31, 1996, the Company had a $2,895,000 long-term junior
subordinated note payable due to the Company's Chief Executive Officer bearing
interest at the prime rate plus 3% (11.25% as of December 31, 1996). An
agreement was signed by the Chief Executive Officer on October 30, 1996 that
provided for subordination of this junior subordinated note to debt outstanding
to a major commercial bank (see Note 7). This note was amended on June 1, 1997
whereby provisions of the subordination were removed and all principal and
unpaid interest was payable to him on November 1, 1997. The Chief Executive
Officer had advanced the Company funds periodically, prior to 1993, to meet
certain short-term operating cash requirements. Accrued interest on this debt
totaled $54,000 as of December 31, 1996. The debt was repaid in full during
1997. The Chief Executive Officer had 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 Chief Executive Officer exercised options to
purchase 1,280,000 shares of Common Stock with an exercise price of $0.29365 per
share during 1997.
 
     In April 1997, the Company loaned a total of $892,195 to certain employees
of the Company, of which $550,923 was loaned to the Company's Vice President,
U.S. Sales under a full-recourse promissory note. Total accrued interest
included in loans to officers and employees amounted to $35,128, of which
$23,456 related to this officer's loan. 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.
 
     A director of the Company, who is also the brother of the Chief Executive
Officer, 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
$309,000, $284,000 and $77,000 in the years ended December 31, 1995, 1996 and
1997, respectively.

NOTE 16. 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 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 14) 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; (iii) the termination of the Company's obligation to supply
contact lenses under the September 30, 1992 purchase and supply agreement (See
Note 14); and (iv) the termination of a limitation on the Company's right to
sell certain contact lenses directly into the United Kingdom and a limitation on
AVCL's right to sell certain contact lenses in North and South America. The
Company paid $3,333,000 to the defendants upon consummation of the settlement
agreement and an additional $6,667,000 upon the closing of the Company's initial
public offering in August, 1997.
 
     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 1995, 1996, and 1997 of $1,320,000, $2,513,000 and
$56,000, 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 17. OTHER COMMITMENTS
 
     Commitments for the remodeling of existing facilities, construction of new
facilities and purchase of capital equipment over the next year are
approximately $2,849,000 and $8,592,000, respectively, as of December 31, 1996
and December 31, 1997.
 
NOTE 18. SUBSEQUENT EVENTS
 
  Financing
 
     Ocular Sciences Puerto Rico has entered into a letter of intent and is
negotiating the final terms of an agreement with The Puerto Rico Industrial
Development Company ("PRIDCO") to manage the construction of a new building in
Puerto Rico that will be leased by Ocular Sciences Puerto Rico as its
manufacturing facility, upon completion of construction. Ocular Sciences Puerto
Rico plans to use term loans under the Amended Credit Agreement to finance the
building construction as well as the leasehold improvements (see Note 7). Under
the anticipated agreement, PRIDCO would reimburse Ocular Sciences Puerto Rico
for up to a maximum of $3,470,000 for certain structural construction costs of
the facility at the end of the construction project, as specified in the

   Description of graphics in Registration Statement dated February 20, 1998
                and the Preliminary Prospectus included therein

Inside Front Cover

The inside front cover of the Preliminary Prospectus contains a text that reads
"SUPERIOR CONTACT LENS PERFORMANCE" at the top of the page on the left hand
side. On the right hand side of the page is a photographic image of the right
half of a woman's face. Her eye is circled and lines are drawn to 5 points on
the page where graphics are included. The first line from the woman's face
extends to the text on the top left of the page that reads "SUPERIOR CONTACT
LENS PERFORMANCE."

The second line from the graphic of the face points to a graphic containing text
reading as follows:

        "MORE COMFORTABLE
             -- Significant wearer requirement
             -- Thin, molded edge reduces lid sensation
             -- Sophisticated lens design enhances comfort."

This text is followed by a schematic diagram of a cross-section of a contact
lens, identifying the "low edge apex," the "CN bevel," the "constant center
thickness," the "lenticulated carrier" and the "constant edge thickness."

The next line from the face points to a graphic containing text reading as
follows:

        "EASE OF HANDLING
             -- Formulated, manufactured and designed for optimal lens shape
                retention 
             -- Easy to tell if inside out and to place on the eye
             -- In an independent comparative study, more patients preferred
                Biomedics 55 than the leading disposable brand for comfort and
                lens handling."

Under this text is a picture of a contact lens on the tip of a finger.

The fourth line from the graphic of the face points to graphics on the lower
left side of the page containing text reading as follows:

        "SCALABLE MANUFACTURING TECHNOLOGY
             -- Dry cast molding enhances performance
             -- Designed for low cost/high volume production."

Under this text are two photographic images. The first is a photograph of a
production line, with text underneath identifying it as "automated molding
machines." The second, located to the right
<PAGE>   97
of the production line graphic, is a photographic image of robotic lens
demolding equipment. Text underneath the picture reads "Robotic lens demolding".

The fifth line from the graphic of the face points to the bottom right side of
the page, ending at a graphic of the Company's logo followed by text that reads
"Better lenses, better care."

Inside Back Cover

The inside back cover of the Preliminary Prospectus contains text at the top of
the page reads "A PROVEN STRATEGY FOR SUCCESS." Underneath this text is text
that reads "RAPID GROWTH WITH FOCUS ON DISPOSABLE REPLACEMENT REGIMENS."
Underneath this text are two bar charts side by side. At the top of the bar
chart on the left is text reading "Revenues ($millions). Bars indicate revenue
levels for each year from 1993 through 1997, as follows: 1993, $38.5 million;
1994 $48.5 million; 1995, $68.1 million; 1996, $90.5 million and 1997, $118.6
million. Text immediately under this chart reads "Company Revenue Growth." At
the top of the bar chart on the right is text reading "% of total units." Bars
for each year from 1993 through 1997 are superimposed with percentages as
follows: 1993, 19.1%; 1994, 53.0%; 1995, 73.4%; 1996, 83.5% and 1997, 89.6%.
Each bar is orange at the top and blue at the bottom, in varying amounts
corresponding to the proportions represented by these percentages. Superimposed
over the lower right portion of the bar chart is a graphic consisting of a box
containing text identifying the blue portion of each bar as representing
"Disposable Replacement" and identifying the orange portion of each bar as
representing "Annual Replacement." Text immediately underneath the chart reads
"Company sales by Replacement Regimen."

        The graphic in the middle left of the page is a photographic image of
two office cubicles, each containing an office in which a person wearing a
headset is seated at a desk on which there is a computer. Superimposed over the
lower portion of this picture is a photographic image of an attractive
wholesome-looking woman's face; the woman is wearing a headset. Also
superimposed over the picture of the cubicles is text that reads
"TELEMARKETING." Text to the right of these pictures, in the center right of the
page, reads as follows:

        "CONTINUAL FOCUS ON REDUCTION OF MANUFACTURING COSTS AND COST-TO-SERVE

        MANUFACTURING IN LAST 4 YEARS:
                Production costs reduced 73% per lens
                Production volumes increased 876%

        COST-TO-SERVE MINIMIZED:

             Automated distributions systems".

A graphic at the bottom of the page contains text extending across the page
that reads "WORLDWIDE BRAND SEGMENTATION BY DISTRIBUTION CHANNEL FOR BETTER
PATIENT RETENTION"  Underneath this text, lined up from left to right across
the page, are pictures of five boxes of different brands of the Company's
contact lenses; immediately underneath each box is text.  Under a box labeled
"HYDRON BIOMEDICS 55" are the words "Private Practitioners."  Under a box
labeled "UltraFlex 7/14 55 VISIBILITY TINTED CONTACT LENSES" are the words
"Retail Optical Chain."  Underneath a box labeled "Clinasoft 55 VISIBILITY
TINTED CONTACT LENSES" are the words "Private Label for Private Practitioners."
Underneath a box labeled "Hydrovue 55 VISIBILITY TINTED CONTACT LENSES" are the
words "Private label for Retail Chain".

        LEVERAGING OCULAR SCIENCES TECHNOLOGY 
        AND MANUFACTURING SCALE WITH ESTABLISHED
        COMPANIES IN KEY MARKETS."

At the bottom right side of the page is a graphic of the Company's logo

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
 
     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.

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 4,030,000 shares of the Common Stock
(par value $0.001 per share) of the Company (the "Firm Shares"), of which 30,000
shares are to be issued and sold by the Company and 4,000,000 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 July 30, 1997 (the "Reincorporation"). For the purposes of Section
1 hereof, all references to "Company" shall also refer to the Predecessor prior
to the Reincorporation.

                  A Selling Stockholder also proposes to sell to the several
Underwriters not more than an additional 604,500 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.

                  1. REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The Company
represents and warrants to and agrees with each of the Underwriters that:

                  (a) The Registration Statement has become effective; no stop
         order suspending the effectiveness of the Registration Statement is in
         effect, and 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 


                                       1


<PAGE>   3
         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.

                  (c) The Company 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 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.

                  (d) Other than Ocular Sciences Puerto Rico Inc., a Delaware
         corporation ("OSI Puerto Rico"), Ocular Sciences Canada Corporation, a

         and prior to the Closing Date:

                                    (i) there shall not have occurred any
                  downgrading, nor shall any notice have been given of any
                  intended or potential downgrading or of any review for a
                  possible change that does not indicate the direction of the
                  possible change, in the rating accorded any of the Company's
                  securities by any "nationally recognized statistical rating
                  organization," as such term is defined for purposes of Rule
                  436(g)(2) under the Securities Act; and

                                    (ii) there shall not have occurred any

                  manner contemplated in the Prospectus.

                  (b) The Underwriters shall have received on the Closing Date a

         all of the agreements and satisfied all of the conditions on its part
         to be performed or satisfied hereunder on or before the Closing Date.

                  the captions "Risk Factors--Risk of Regulatory Action" 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,

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:

                  Custody Agreement and Powers of Attorney of such Selling
                  Stockholder does not contravene any provision of applicable

                  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

                  sale of the Shares (as to which such counsel need not opine);

                                    (iii) to such counsel's knowledge, such

                  names of the Underwriters (or their nominees) in the stock

                  of the records of any governmental authority or any third
                  person), the Underwriters will be the owners of the Shares,

                                    (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;

                                    (ii) all of the issued shares of capital
                  stock of OSL have been duly validly authorized and issued, are
                  fully paid up or credited as fully paid up, and owned directly
                  by the Company, free and clear of all liens and encumbrances
                  (other than the lien of Commercial Bank - California as
                  described in the Prospectus);

                                    (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 Hestres, 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 the
         first clause of subparagraph (c)(vi), in subparagraphs (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
Underwriter as follows:

                  (a) To furnish to you, without charge, four (4) signed copies
         of the Registration Statement (including exhibits thereto) and for
         delivery to each other Underwriter a conformed copy of the Registration
         Statement (without exhibits thereto) and to furnish to you in New York
         City, without charge, prior to 5:00 P.M. local time on the business day
         next succeeding the date of this Agreement and during the period
         mentioned in paragraph (c) below, as many copies of the Prospectus and
         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
         proposed amendment or supplement and not to file any such proposed
         amendment or supplement to which you reasonably object, and to file
         with the Commission within the applicable period specified in Rule
         424(b) under the Securities Act any 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.


                                       12


<PAGE>   14
                  (d) To endeavor to qualify the Shares for offer and sale under
         the securities or Blue Sky laws of such jurisdictions as you shall
         reasonably request.

                  (e) To make generally available to the Company's security
         holders and to you as soon as practicable an earnings statement
         covering the twelve-month period ending March 30, 1999 that satisfies
         the provisions of Section 11(a) of the Securities Act and the 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
         fees, disbursements and expenses of the Company's counsel and the
         Company's accountants in connection with the registration and delivery
         of the Shares under the Securities Act and all other fees or expenses
         in connection with the preparation and filing of the Registration
         Statement, any preliminary prospectus, the Prospectus and amendments
         and supplements to any of the foregoing, including all printing costs
         associated therewith, and the mailing and delivering of copies thereof
         to the Underwriters and dealers, in the quantities hereinabove
         specified, (ii) all costs and expenses related to the transfer and
         delivery of the Shares to the Underwriters, including any transfer or
         other taxes payable thereon, (iii) the cost of printing or producing
         any Blue Sky memorandum in connection with the offer and sale of the
         Shares under state securities laws, including filing fees and the
         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
         connection with the review and qualification of the offering of the
         Shares by the National Association of Securities Dealers, Inc., (v) all
         costs and expenses incident to listing the Shares on the Nasdaq
         National Market, (vi) the cost of printing certificates representing
         the Shares, (vii) the costs and charges of any transfer agent,
         registrar or depositary, (viii) the costs and expenses of the Company
         relating to investor presentations on any "road show" undertaken in
         connection with the marketing of the offering of the Shares, including,
         without limitation, expenses associated with the production of road
         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, (ix) any expenses of Selling Stockholders under Section 8
         below and (x) all other costs and expenses incident to the performance
         of the obligations of the Company hereunder for which provision is not
         otherwise made in this Section. It is understood, 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.

                  8. EXPENSES OF SELLING STOCKHOLDERS. The Underwriters shall
not be liable for any expenses of any Selling Stockholders in connection with
the sale of their Shares in the offering. As between the Company and the Selling
Stockholders, Selling Stockholder expenses will be paid by the Selling
Stockholders and/or the Company subject to the terms set forth in that certain
Registration Rights Agreement, dated as of October 30, 1992, as amended February
27, 1997, by and among the Company and the various signing stockholders thereto,
which include the Selling Stockholders. To the extent not set forth or provided
for therein, as between the Underwriters on the one hand, and the Company on the
other, all Selling Stockholder expenses shall be borne by the Company.

                  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 


                                       13


<PAGE>   15
         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.

                  (b) 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.

                  (c) 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.

<PAGE>   16
                  (d) 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) or (c) 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.

                  (e) To the extent the indemnification provided for in
         paragraph (a), (b) or (c) 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 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 


                                       15


<PAGE>   17
         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.

                  (f) 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 (e) 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.

                  (g) 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 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.

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 4
November 1997, the Company was in Good Standing as herein defined. By GOOD
STANDING (a phrase which has no recognised meaning under English law), we mean
that according to a certificate dated 4 November 1997 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.

<PAGE>   22
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 Pledge Agreement and delivery of the same
together with the delivery of the share certificates referred to in paragraph
2.6 and the stock transfer form referred to in paragraph 2.5 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:

4.6.1  any Event of Default (as defined in the 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;

<PAGE>   23
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 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 Pledge
Agreement;

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
3.6, on our telephone enquiry made on 5 November 1997 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 4 November 1997. 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 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 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 judgement of a foreign Court, the
Courts of England will not simply register and enforce such judgment.  It would 
be necessary to commence fresh 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 100 (or part thereof) of
consideration and accordingly the Bank will be required to submit the stock
transfer form referred to in paragraph 2.5 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.

Yours faithfully

         only on the last Business Day of the then current Interest Period
         applicable to such Eurodollar Rate Advance.

                  (f) EXCESS EXPOSURE. If, at any time for any reason, the sum
         of (i) the aggregate principal amount of outstanding Facility A
         Advances, PLUS (ii) the outstanding Letter of Credit Usage, exceeds the
         Facility A Availability in effect at such time, then Ocular Sciences
         shall immediately, without notice or demand, repay Facility A Advances
         in an amount equal to such excess.

                  (g) CHANGE OF CONTROL. Each 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 to such Borrower shall be due and payable in
         full, (ii) with respect to a Change of Control of Ocular Sciences,
         Ocular Sciences 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.

                  SECTION 2.6. INTEREST. Each 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 Amount attributable to Base Rate
         Advances, with all such interest payable quarterly in arrears on the
         last day of each January, April, July and October, commencing January
         31, 1998, and (i) with respect to the Facility A Advances, on the
         Facility A Maturity Date, and (ii) with respect to the Facility B
         Advances, on such other date that such Advances are repaid, or required
         to be repaid, in full.

                  (b) FACILITY A EURODOLLAR RATE ADVANCES. Whenever such Advance
         is a Eurodollar Rate Advance under Facility A, 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 Amount attributable to Facility A
         Eurodollar Rate Advances, 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 ninety (90) days, on the day which occurs ninety
         (90) days after the first day of such Interest Period.

                  (c) FACILITY B EURODOLLAR RATE ADVANCES. Whenever such Advance
         is a Eurodollar Rate Advance under Facility B, 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 Amount attributable to Facility B
         Eurodollar Rate Advances, with all interest so accrued payable on the
         last day of such Interest Period, and if 



                                       23
<PAGE>   41

         such Interest Period has a duration of more than ninety (90) days, on
         the day which occurs ninety (90) days after the first day of such
         Interest Period.

                  (d) NEGOTIATED RATE ADVANCES. Whenever such Advance is a
         Negotiated Rate Advance under Facility B, a rate per annum equal on
         each day during the Interest Period for such Negotiated Rate Advance to
         the sum of the Negotiated Rate for such Interest Period determined for
         such day PLUS the Applicable Amount attributable to Negotiated Rate
         Advances, with all interest so accrued payable quarterly in arrears on
         the last day of each January, April, July and October, commencing July
         31, 1999 and on such other date that the Facility B Advances are
         repaid, or required to be repaid, in full.

                  (e) DEFAULT INTEREST. Upon written notice from the Lender to a
         Borrower, from and after the occurrence of an Event of Default, all
         amounts outstanding to such Borrower 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 2.7. INTEREST RATE DETERMINATION AND PROTECTION.

                  (a) DETERMINATION OF EURODOLLAR RATE AND NEGOTIATED RATE. The
         Eurodollar Rate and Negotiated Rate for each Interest Period applicable
         to a Eurodollar Rate Advance or a Negotiated Rate Advance shall be
         determined by the Lender at or before 11:00 a.m. (Pacific time) one (1)
         Business Day before the first day of such Interest Period.

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

                  (c) ALTERNATIVE INTEREST RATE. If, with respect to any
         Eurodollar Rate Advance or Negotiated Rate Advance, the Lender
         determines that by reason of any change in applicable law or regulation
         or regulatory requirement, or in the interpretation or application
         thereof, or compliance by the Lender with any request (whether or not
         having the force of law) of any banking authority, or of any change in
         national or international financial, political or economic conditions
         or currency exchange rates or exchange controls, the Lender determines
         that (i) adequate and reasonable means do not exist for ascertaining a
         Eurodollar Rate or a Negotiated Rate, as applicable, for any requested
         Interest Period, (ii) the rate at which deposits in any Eurodollar Rate
         or Negotiated Rate do not accurately reflect the cost to the Lender of
         making or maintaining such Eurodollar Rate Advance or Negotiated Rate
         Advance for any Interest Period, or (iii) Dollar deposits are not
         available to the Lender in an amount substantially equal to such
         Eurodollar Rate Advance or Negotiated 



                                       24
<PAGE>   42

         Rate Advance and for a period equal to such Interest Period, then the
         Lender shall forthwith so notify the Borrowers and thereupon (A) each
         Eurodollar Rate Advance or Negotiated 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 or
         Negotiated Rate Advances shall be suspended until the Lender shall
         notify the Borrowers that the circumstances causing such suspension no
         longer exist.

                  (d) MINIMUM AMOUNTS. No Advance of LESS than $1,000,000 may be
         made or continued as, or converted into, Eurodollar Rate Advances or
         Negotiated Rate Advances. If at any time the outstanding principal
         amount of any Eurodollar Rate Advance is reduced to less than
         $1,000,000, then such Advance shall automatically and immediately
         convert into a Base Rate Advance.

                  (e) 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 2.8. VOLUNTARY CONVERSION OF ADVANCES.

                  (a) NOTICE OF CONTINUANCE/CONVERSION. Subject to the
         provisions of Section 2.7 and Section 2.11, a 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 preceding Business Day,
         (i) convert Base Rate Advances into either Eurodollar Rate Advances or
         Negotiated Rate Advances; provided, however, that conversions into
         Negotiated Rate Advances may only be effected from and after May 1,
         1999; (ii) convert Eurodollar Rate Advances into either Base Rate
         Advances or Negotiated Rate Advances; provided, however, that
         conversions into Negotiated Rate Advances may only be effected from and
         after May 1, 1999; (iii) convert Negotiated Rate Advances into either
         Base Rate Advances or Eurodollar Rate Advances; (iv) continue
         Eurodollar Rate Advances as Eurodollar Rate Advances; or (iv) continue
         Negotiated Rate Advances as Negotiated Rate Advances, but (A) such
         Borrower may convert either a Eurodollar Rate Advance or a Negotiated
         Rate Advance only on the last day of an Interest Period; (B) such
         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; (C) such Borrower may continue a Negotiated
         Rate Advance as a Negotiated Rate Advance only as of the last day of an
         Interest Period for such Negotiated Rate Advance, and (D) no Advance
         may be converted into or continued as either a Eurodollar Rate Advance
         or a Negotiated Rate Advance at any time when an Event of Default or
         Potential Default has occurred and is continuing.



                                       25
<PAGE>   43

                  (b) TELEPHONIC NOTICE. In lieu of delivering a Notice of
         Continuance/Conversion, a 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 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, then the Lender shall
         notify such Borrower of such discrepancy and in such case the
         telephonic request shall govern as to the terms of such Notice of
         Continuation/Conversion. 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 requested
         continuance or conversion; (ii) whether such Advance is a continuance
         or conversion of an outstanding Advance; (iii) the principal amount of
         the Advance to be converted or continued; (iv) whether such Advance is
         a Facility A Advance or a Facility B Advance; and (v) in the case of an
         Advance which is converted into or continued as either a Eurodollar
         Rate Advance or a Negotiated Rate Advance, the duration of the Interest
         Period for such Advance.

                  (d) BASE RATE ADVANCES. Unless a Eurodollar Rate or Negotiated
         Rate, as appropriate, 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 2.9. FUNDING LOSSES. If (a) any Eurodollar Rate Advance or
Negotiated Rate is repaid or converted into a Base Rate Advance on any day other
than the last day of the relevant Interest Period (whether as a result of any
optional prepayment, mandatory prepayment, payment upon acceleration, mandatory
conversion or otherwise), (b) a Borrower fails to borrow, continue or convert
any Eurodollar Rate Advance or Negotiated Rate Advance in accordance with a
Notice of Borrowing, a Notice of Continuance/Conversion or a telephonic request
delivered to the Lender (whether as a result of the failure to satisfy any
applicable conditions or otherwise); or (c) a Borrower fails to make any
prepayment of either a Eurodollar Rate Advance or a Negotiated Rate Advance in
accordance with any notice of prepayment delivered to the Lender, then such
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 or
Negotiated Rate Advances. Breakage Costs shall be payable only if demanded
within ninety (90) days after the end of the applicable Interest Period and



                                       26
<PAGE>   44

shall be due within thirty (30) days after demand. Demand shall be made by
delivery to a Borrower of a certificate of the Lender, setting forth in
reasonable detail the calculation of the Breakage Costs for which demand is
made, and such certificate shall, in the absence of manifest error, be
conclusive and binding on such Borrower. The calculation of any amounts payable
to the Lender shall be made as though the Lender shall have actually funded or
committed to fund the relevant Eurodollar Rate Advance or Negotiated Rate
Advance through the purchase of an underlying deposit in an amount equal to such
Eurodollar Rate Advance or Negotiated Rate Advance, respectively, and having a
maturity comparable to the relevant Interest Period; PROVIDED, HOWEVER, that the
Lender may fund any Eurodollar Rate Advance or Negotiated 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 a
Borrower shall be obligated to repay either Eurodollar Rate Advances or
Negotiated Rate Advances pursuant to Section 2.11 on a date that is not the last
day of the Interest Period for such Advance, then such 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
principal amount of either the Eurodollar Rate Advances or Negotiated Rate
Advances being repaid PLUS interest to the date such prepayment will be applied.
Such deposit shall be (i) held by the Lender on terms and conditions
satisfactory to the Lender in its sole discretion, and (ii) applied by the
Lender to such Eurodollar Rate Advances or Negotiated Rate Advances on the last
day of the Interest Period therefor.

         SECTION 2.10. INCREASED COSTS.

                  (a) INCREASE IN COST. If, due to either (i) the introduction
         of, 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 or Negotiated
         Rate Advances, then the applicable 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 within thirty (30) days after demand. Demand shall be made by
         delivery to such 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 such 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 by any central bank or other 



                                       27
<PAGE>   45

         Governmental Authority to be maintained by either 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 applicable 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 is
         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 such
         Borrower of a certificate of the Lender setting forth the amount
         demanded. Such certificate shall, in the absence of manifest error, be
         conclusive and binding on such Borrower.

         SECTION 2.11. ILLEGALITY. Notwithstanding any other provision of this
Agreement, if the Lender shall notify the Borrowers that the introduction of,
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 either
Eurodollar Rate Advances or Negotiated Rate Advances or to fund or maintain
either Eurodollar Rate Advances or Negotiated Rate Advances hereunder, then (i)
the obligation of the Lender to make or continue, or to convert Advances into,
Eurodollar Rate Advances or Negotiated Rate Advances shall be suspended until
the Lender shall notify the Borrowers that the circumstances causing such
suspension no longer exist, and (ii) the Borrowers shall forthwith either (A)
prepay in full all Eurodollar Rate Advances and Negotiated Rate Advances of the
Lender then outstanding, together with interest accrued thereon and Breakage
Costs related thereto, or (B) convert all Eurodollar Rate Advances and
Negotiated 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 2.12. PAYMENTS AND COMPUTATIONS.

                  (a) PAYMENTS. Each 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
         2.17(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.



                                       28
<PAGE>   46

                  (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.

         SECTION 2.13. TAXES.

                  (a) NET PAYMENTS. Any and all payments by either 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 either
         Borrower is required by law to deduct any Taxes from or in respect of
         any sum payable hereunder to the Lender, then (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)
         such Borrower shall make such deductions, and (iii) such 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, each 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. Each 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 within thirty (30)
         days after written demand therefor.

                  (d) EVIDENCE OF PAYMENTS. Within thirty (30) days after the
         date of any payment of Taxes, each 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, each Borrower will furnish to the
         Lender, at such address, a certificate from each appropriate taxing
         authority, or an opinion of counsel 



                                       29
<PAGE>   47

         acceptable to the Lender, in either case stating that such payment is
         exempt from or not subject to Taxes.

         SECTION 2.14. COLLATERAL AND GUARANTIES. Payment and performance of
all Obligations of either Borrower or any of their Subsidiaries under this
Agreement and all other Loan Documents shall be secured in accordance with the
Collateral Documents. Payment and performance of all Obligations of Ocular
Sciences under this Agreement and all other Loan Documents shall be
unconditionally guaranteed by the Subsidiary Guarantors pursuant to the
Subsidiary Guaranty. Payment and performance of all Obligations of O.S.I. Puerto
Rico under this Agreement and all other Loan Documents shall be unconditionally
guaranteed by Ocular Sciences pursuant to the Parent Guaranty.

         SECTION 2.15. ISSUANCE OF LETTERS OF CREDIT. Upon the request of Ocular
Sciences, 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 Ocular Sciences; 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 shall be opened if at such time the sum of (a) the Letter of Credit
Usage then outstanding (after giving effect to the requested new Letter of
Credit), PLUS (b) the aggregate principal amount of Facility A Advances then
outstanding, shall exceed the Facility A Amount existing at such time. The
issuance of each Letter of Credit shall be made on at least five (5) Business
Days' prior written notice from Ocular Sciences 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 have an expiration date
later than the Facility A Maturity Date. Each Letter of Credit shall be issued
for lawful purposes occurring in the ordinary course of business of Ocular
Sciences.

         SECTION 2.16. 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

<PAGE>   48

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, (a) 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 Ocular Sciences of the receipt and amount of such draft and
the date on which payment thereon will be made, (b) 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 (c) Ocular Sciences 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 a Facility A Advance if Ocular
Sciences meets all of the conditions precedent for such an Advance and complies
with the requirements of Section 2.1). If Ocular Sciences does not reimburse the
Lender within the time set forth above, then Ocular Sciences 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 Ocular Sciences under
this Section 2.16 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:

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

                  (ii) the existence of any claim, setoff, defense or other
         right which Ocular Sciences or any other Person may at any time have
         against the beneficiary under any Letter of 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;

                  (iii) 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;

                  (iv) 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

                  (v) 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 (A) 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, 



                                       31
<PAGE>   49

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 (B) 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.

                  (a) Ocular Sciences agrees to pay to the Lender, with respect
         to each standby Letter of Credit, an issuance fee equal to the then
         effective Applicable Amount (i.e. the per annum interest margin)

         the rate customarily charged by the Lender at the time in like
         circumstances, payable prior to issuance of such Letter of Credit.

                  (c) Ocular Sciences 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 2.17 are
         non-refundable.

Commerce most recently at the time of issuance of any Letter of Credit shall

                         REPRESENTATIONS AND WARRANTIES

         SECTION 4.1. REPRESENTATIONS AND WARRANTIES OF THE BORROWERS. Each
Borrower represents and warrants as follows:

                  (a) ORGANIZATION. Each Loan Party is a corporation, limited
         liability company or partnership duly organized, validly existing and
         in good standing under the laws of the jurisdiction in which it is
         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
         perform each Loan Document to which it is a party, and (iii) to take
         all action necessary to consummate the transactions contemplated under
         each Loan Document to which it is a party.

                  (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, its
         governing authority), and neither contravene its certificate or
         articles of incorporation or by-laws (or, in case of a Loan Party that
         is not a corporation, its governing agreements) nor result in or
         require the creation of any Lien (other than pursuant to the Pledge
         Agreement) upon any of its property or assets.

                  (d) SUBSIDIARIES AND OWNERSHIP OF CAPITAL STOCK. Set forth on
         Schedule 4.1(d) or on Schedule A to the Pledge Agreement, as such
         Schedule may be amended pursuant to Section 5.2(e), is a complete list
         of all direct and indirect Subsidiaries of Ocular Sciences. 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 interests 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. Other than the shares
         evidencing the capital stock of Ocular Sciences Hungary Ltd., all such
         shares, capital stock or other equity, ownership or profit interests
         are certificated securities evidenced and represented by certificates
         issued in bearer or registered form. The outstanding capital stock of
         each such Subsidiary is duly authorized, validly issued, fully paid and



                                       36

         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 set forth on Schedule 4.1(e), and (ii)
         filings and other actions required in connection with the exercise by
         the Lender of its remedies in respect of the Pledged Shares (as such
         term is defined in the Pledge Agreement).

                  (f) BINDING AND ENFORCEABLE. This Agreement 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.

                  (g) FINANCIAL INFORMATION. The consolidated balance sheets of
         Ocular Sciences and its Subsidiaries as at December 31, 1995 and
         December 31, 1996 and the related income and cash flow statements for
         the periods then ended, each other financial statement of Ocular
         Sciences 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
         Ocular Sciences 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, 1996, 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 each Borrower's knowledge,
         overtly threatened actions or proceedings against or directly affecting
         any Loan Party before any court, governmental agency or arbitrator,
         other than any action or proceeding that would not subject either
         Borrower or any of their Subsidiaries 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 each Borrower's knowledge,

         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
         either 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 Borrower and each of their
         Subsidiaries 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 either
         Borrower or any of their Subsidiaries in excess of $500,000.

                  (n) MARGIN REGULATIONS. No proceeds of any Advance will be
         used for any purpose that requires 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. Each Borrower and their Subsidiaries
         are engaged in the lines of business described on Schedule 4.1(o) and
         activities substantially similar or reasonably incidental thereto.

                  (p) ENVIRONMENTAL MATTERS. Except as set forth on Schedule
         4.1(p), as it may from time to time be amended by either Borrower, no
         Material Environmental Claim is pending or, to the knowledge of each
         Borrower, overtly threatened against either Borrower or any of their
         Subsidiaries or any 



                                       38

         of their past or present property or assets. Except as set forth on
         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 each Borrower and their Subsidiaries comply and, to the
         knowledge of each 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 each Borrower, nothing has occurred which would
                  cause the loss of such qualification or tax-exempt status.

                           (iii) Except as set forth on 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
                  either Borrower or any ERISA Affiliate is or may be liable;
                  (B) neither of the Borrowers 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 each Borrower, is reasonably expected to
                  occur, and (D) neither of the Borrowers nor any ERISA
                  Affiliate has maintained any Welfare Plan which provides, or
                  requires either Borrower or any ERISA Affiliate to provide,
                  medical or other welfare benefits to any participant after the
                  termination of such participant's employment with such
                  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 of the Borrowers 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 



                                       39
<PAGE>   57

                  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; NO INFRINGEMENT. Each Borrower and their
         Subsidiaries have 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), and, to the knowledge of each Borrower, such assets do
         not infringe upon any patent, trademark, copyright or other legally
         protected interest of any other Person. 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) UNDISCLOSED LIABILITIES. Except as set forth on Schedule
         4.1(s), neither of the Borrowers nor any of their Subsidiaries has any
         liabilities, contingent or otherwise, which 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.

                  (t) NO NEGATIVE PLEDGES. Neither of the Borrowers nor any of
         their Subsidiaries are parties to or subject to any agreement, document
         or instrument which would restrict or prevent them from granting first
         priority Liens upon their assets to the Lender, except the agreements,
         documents or instruments existing on the Closing Date pursuant to which
         Liens not prohibited by the terms of this Agreement have been created.

         and make copies thereof or abstracts therefrom, and to discuss its
         affairs, finances and accounts with its officers, employees and
         independent public accountants, all at the expense of such Borrowers
         and at such reasonable times during normal business hours and as often
         as may be reasonably requested (but not more than twice per calendar
         year, unless an Event of Default or Potential Default shall have

         apply), upon at least three (3) Business Days' advance notice to such
         Borrowers, except that when an Event of Default exists, the Lender may

<PAGE>   60

                  any of their Subsidiaries as the Lender from time to time may
                  reasonably request.

         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 patents, 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 either
         Borrower or any of their Subsidiaries may consummate any merger or
         consolidation permitted under Section 5.3(g), and PROVIDED, FURTHER,
         that neither of the Borrowers nor any of their Subsidiaries shall be
         required to preserve or maintain any right, asset, goodwill, business
         or franchise if such Borrower or such Subsidiary shall determine that
         the preservation thereof is no longer desirable in the conduct of the
         business of such Borrower or such Subsidiary, as the case may be, and
         that the loss thereof is not disadvantageous in any material respect to
         such Borrower, such Subsidiary or the Lender.

                  (e) NEW SUBSIDIARIES. Promptly (but in any event within ten
         (10) Business Days) after the date on which either a new (direct or

         deliver such amended Schedule to the Lender, and (iii) promptly (but in
         any event within twenty (20) Business Days) after the formation,
         acquisition or change of each Material Subsidiary, (A) deliver to the
         Lender all stock certificates and other instruments added to the
         Collateral thereby (to the extent required by the Pledge Agreement),
         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 Ocular Sciences' equity interests therein need be delivered to
         the Lender); (B) amend Schedule A of the Pledge Agreement in light of
         such event and deliver such Schedule to the Lender; (C) cause each such
         Material Subsidiary (but excluding any Foreign Subsidiary) to execute
         and deliver a joinder to the Subsidiary Guaranty; (D) if the Material
         Subsidiary is indirectly owned or controlled by Ocular Sciences, at the
         Lender's request cause such Subsidiary of Ocular Sciences that directly
         controls each such Material Subsidiary (including each Foreign
         Subsidiary to the extent of sixty-five percent (65%) of its equity
         interest therein) to become a party to the Pledge Agreement by
         executing a joinder thereto in form and substance acceptable to the
         Lender, and (E) deliver 



                                       43
<PAGE>   61

         to the Lender in respect of each such Material Subsidiary of Ocular
         Sciences an opinion of counsel substantially in the form of Exhibit
         C-3.

                  (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 either Borrower determines in good faith that
         it is not in the best interests of such Borrower and its Subsidiaries
         to do so.

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

                  (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

                  by either Borrower or any of their Subsidiaries and activities
                  reasonably incidental thereto, so long as (A) the total
                  consideration (including cash, Debt incurred and value of
                  stock) paid by the Borrowers and their Subsidiaries for all

         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
         Borrowers or any ERISA Affiliate in excess of $1,000,000 in the
         aggregate; (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 Borrowers or
         any ERISA Affiliate in excess of $1,000,000 in the aggregate; or (iv)
         permit the total Unfunded Pension Liabilities (using the actuarial

         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 either Borrower or any
         of their Subsidiaries or to enter into any other lawful transaction
         with either Borrower or any of their Subsidiaries, except limitations
         and restrictions set forth in the Loan Documents.

                                EVENTS OF DEFAULT

         SECTION 6.1. EVENTS OF DEFAULT. If any of the following events (each,
an "Event of Default") shall occur and be continuing:

                  (a) NON-PAYMENT OF PRINCIPAL. Either Borrower fails to pay
         when due any principal of any Advance; or

                  (b) NON-PAYMENT OF INTEREST. Either Borrower fails to pay when
         due any interest payable under Section 2.6 or any fee payable under
         Section 2.4 or Section 2.17 and such failure continues for three (3)
         Business Days; or

                  (c) NON-PAYMENT OF OTHER OBLIGATIONS. Either Borrower fails to
         pay any other payment Obligation, and such failure continues for ten
         (10) Business Days after either (i) it is acknowledged in writing by
         such Borrower, or (ii) written notice thereof is given to such Borrower
         by the Lender; or

                  (d) REPRESENTATIONS AND WARRANTIES. Any representation or
         warranty made by any Loan Party under or in connection with any Loan
         Document proves to have been incorrect in any material respect when
         made; or

                  (e) FINANCIAL AND NEGATIVE COVENANTS. Either Borrower fails to
         perform or observe any term, covenant or agreement set forth in Section
         5.1 or Section 5.3; or

                  (f) REPORTING AND COLLATERAL COVENANTS. Either Borrower fails
         to perform or observe any term, covenant or agreement set forth in

         by the Lender; or



                                       53
<PAGE>   71

                  (g) OTHER AGREEMENTS. Either Borrower or any of their
         Subsidiaries fails to perform or observe any term, covenant or
         agreement contained in this Agreement or any other Loan Document (other
         than those specifically referred to in any of the preceding paragraphs
         of this Section 6.1) and such failure continues for thirty (30) days
         after either (i) it is acknowledged in writing by such Borrower or such
         Subsidiary, or (ii) written notice thereof is given to such Borrower or
         such Subsidiary by the Lender; or

                  (h) DEFAULT AS TO OTHER DEBT. Either Borrower or any of their
         Subsidiaries (i) fails to pay, when due and payable (whether at the
         scheduled maturity or upon any required prepayment, acceleration,
         demand or otherwise), any principal of or premium or interest on any
         Debt (except any Advances) 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
         breach, default or event of default to occur under any indenture or
         agreement governing any Debt (except any Advances) outstanding in a
         principal amount of at least $1,000,000, and such breach, default or
         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 (A) which is the liability
         solely of a Foreign Subsidiary shall be an Event of Default hereunder
         until either (x) it is acknowledged in writing by either Borrower, or
         (y) it continues for ten (10) Business Days after written notice
         thereof is given to either Borrower by the Lender, and (B) shall be an
         Event of Default hereunder if, in the case of a wholly-owned Subsidiary
         of either Borrower, such Debt is held entirely by either Borrower or,
         in the case of either Borrower, such Debt is held entirely by one or
         more of its wholly-owned Subsidiaries; or

                  (i) BANKRUPTCY. (i) Either Borrower or any of their
         Subsidiaries are generally not paying its debts as they become due or
         admits in writing its inability to pay its debts generally or makes a
         general assignment for the benefit of creditors, or (ii) any proceeding
         is instituted by or against either Borrower or any of their
         Subsidiaries 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) either Borrower or any of their Subsidiaries



                                       54
<PAGE>   72

         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 either Borrower 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, 1996; 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 either 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 in any Collateral purported to be
         covered thereby, and such event continues for ten (10) Business Days
         after written notice thereof is given to either Borrower, or

                  (n) ERISA. (i) Either 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; (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 in the aggregate; (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; (iv) a Plan that is intended to
         be qualified under Section 401(a) of the Code loses its qualification,
         and with respect to such loss of qualification, either 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 (v) any
         combination of events listed in clauses (ii) through (iv) occurs that
         involves a net increase in 



                                       55
<PAGE>   73

         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
Advances and issue Letters of Credit to be terminated, whereupon the same shall
forthwith terminate and the Facility Amount shall be automatically and
permanently reduced to zero, and (B) shall by notice to the Borrowers, 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 Borrowers; PROVIDED, HOWEVER, that if an order
for relief under the United States Bankruptcy Code is entered at the request or
upon the consent of either Borrower or involuntarily against either Borrower,
then (x) the obligation of the Lender to make Advances and to issue Letters of
Credit shall automatically be terminated and the Facility 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 Borrowers.

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

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 7.5. 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 either 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 either 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 Borrowers 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 7.6. GENERAL INDEMNITY. Each 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 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 



                                       57
<PAGE>   75

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 neither Borrower shall have any indemnity obligation to any
Indemnified Person for any Claim (a) based on or arising from the gross
negligence or willful misconduct of such Indemnified Person or a breach of any
Loan Document or applicable law by an Indemnified Person, or (b) made or
prosecuted by either Borrower. The Borrowers 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 either Borrower from any of its obligations under this Section 7.6
or under Section 7.4. Each 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 each 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 (i) at each Borrower's expense
whenever any Event of Default or Potential Default is continuing, and (ii) at
such Indemnified Person's expense at any other time, and each Borrower and the
attorneys selected by each Borrower shall cooperate in all reasonable respects
with such counsel. Each Borrower shall be entitled to settle any Claim, at each
Borrower's sole cost and expense, without the consent of the Indemnified Person
if (A) no Event of Default or Potential Default is continuing, (B) the
settlement does not and will not, under any circumstances, impose any present or
future payment or performance obligation upon the Indemnified Person, and (C)
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 7.7. ASSIGNMENTS AND PARTICIPATIONS. The Lender may at
any time sell, assign, grant a participation in, or otherwise transfer all or
any part of its rights and obligations under this Agreement (a) without either
Borrower's consent if such transfer is to a Federal Reserve Bank, to an
Affiliate of the Lender or if an Event of Default is continuing, and (b) with
the consent of the Borrowers (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 



                                       58
<PAGE>   76

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 maturity date of Facility A or
Facility B, (iii) postpones any scheduled Facility B payment date, (iv)
decreases the rate of interest applicable to any Advances, (v) releases all or
substantially all of the Collateral or any right to obtain additional
Collateral, or (vi) releases any Guarantor or any right to have an additional
Material Subsidiary (other than a Foreign 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 Borrowers shall continue to deal solely and directly with the
Lender in connection with the Lender's rights and obligations under this
Agreement. The Borrowers hereby authorize the Lender and each such participant
or assignee, in case of default by either Borrower hereunder, to proceed
directly by right of setoff, bankers' lien or otherwise, against any assets of
either Borrower or any of their Subsidiaries which may at the time of such
default be in the hands of the Lender or any such participant or assignee.

         SECTION 7.8. 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 each Borrower and the Lender and their respective successors
and assigns, except that neither Borrower shall have the right to assign its
rights hereunder or any interest herein without the prior written consent of the
Lender.

         SECTION 7.9. 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 Borrower and the Lender consents, for
itself and in respect of its property, to the jurisdiction of those courts. Each
Borrower and the Lender irrevocably waive 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. Each Borrower and the Lender waive
personal service of any summons, complaint or other process, which may be made
by any other means permitted by California law.

         SECTION 7.10. WAIVER OF JURY TRIAL. Each Borrower and the Lender
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. Each 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
each future 



                                       59
<PAGE>   77

amendment, renewal, supplement or modification of any Loan Document and to each
future Loan Document.

         SECTION 7.11. LIMITATION OF LIABILITY. No claim may be made by either
Borrower, any Subsidiary of either Borrower, or any other Person against the
Lender or its Affiliates, directors, officers, employees, attorneys or agents
for any special, indirect or consequential damages or, to the fullest 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 each Borrower (for itself and on behalf of each of
their Subsidiaries) 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.

         SECTION 7.12. CONFIDENTIALITY. The Lender agrees that it will not,
without the prior consent of the Borrowers, disclose any information with
respect to either Borrower which is furnished to the Lender pursuant to this
Agreement and which either Borrower has notified the Lender, in writing,
constitutes confidential information, except (a) to the Lender's directors,
officers, employees, agents and financial and legal advisors under instructions
to maintain confidentiality; (b) to any actual or prospective participant or
assignee under Section 7.7, so long as such participant or assignee agrees to be
bound by the provisions of this Section 7.12; (c) information that is known to
the Lender or its directors, officers, employees, agents or financial and legal
advisors prior to its disclosure by either Borrower; (d) information that has
become publicly available other than by the Lender's improper disclosure; (e)
information that is obtained from any source other than either 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 (f) 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 Borrowers at least three (3) Business Days' prior notice thereof. The
Lender's obligations under this Section 7.12 shall survive the expiration or
termination of this Agreement.

         SECTION 7.13. ENTIRE AGREEMENT. This Agreement, together with the
other Loan Documents, embodies the entire Agreement and understanding among each
Borrower and the Lender and supersedes all prior or contemporaneous agreements
and understandings of such Persons, verbal or written, relating to the subject
matter hereof and thereof.

         SECTION 7.14. TERMINATION OF ORIGINAL CREDIT AGREEMENT. Upon
repayment to the Lender of all Obligations under the Original Credit Agreement,
and 



                                       60
<PAGE>   78

upon satisfaction of all conditions precedent specified in Section 3.1 hereof,
as and when required therein, the Original Credit Agreement shall be deemed
terminated and shall be of no further force and effect, except that (i) all
obligations of Ocular Sciences that by the express terms of the Original Credit
Agreement survive termination thereof shall survive such termination and (ii)
the Lender's obligations under Section 7.12 of the Original Credit Agreement
shall survive such termination. Without limiting the foregoing, Ocular Sciences
shall pay to the Lender all accrued and unpaid amounts owing with respect to
commitment fees and other sums owing to the Lender under the Original Credit
Agreement. As of November 7, 1997, the accrued unpaid commitment fee owing by
Ocular Sciences to the Lender under the Original Credit Agreement is $1,239.59.

         SECTION 7.15. SURVIVAL. Each Borrower's liability for any and all
fees, taxes, compensation, costs, losses, expense reimbursements,
indemnification and other similar Obligations arising under any Loan Document
shall survive the expiration or termination of the commitments of the Lender to
extend credit hereunder and the repayment and retirement of all Advances and
Letters of Credit at any time outstanding hereunder.

         SECTION 7.16. EXECUTION IN COUNTERPARTS. This Agreement may be
executed in any number of counterparts and by different parties hereto in
separate counterparts, each of which when so executed shall be deemed to be an
original and all of which taken together shall constitute one and the same
agreement.

         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
executed by their respective officers thereunto duly authorized as of the date
first above written.

                          FORM OF AMENDED AND RESTATED
                               SUBSIDIARY GUARANTY


                  This AMENDED AND RESTATED SUBSIDIARY GUARANTY, dated as of
November 7, 1997, is made by Ocular Sciences Puerto Rico, Inc., a Delaware
corporation (herein referred to as "O.S.I. Puerto Rico") and each entity that
hereafter executes and delivers a Subsidiary Joinder in substantially the form
set forth as Annex 1 hereto (each such entity, a "Guarantor" and collectively
the "Guarantors") in favor of Comerica Bank-California, a California chartered
bank (the "Lender").

                                    RECITALS

                  A. The Lender has entered into that certain Amended and
Restated Credit Agreement dated as of November 7, 1997 (the "Credit Agreement"),
by and among Ocular Sciences, Inc., a Delaware corporation (formerly known as
O.S.I. Corporation and herein referred to as "Ocular Sciences"), as a Borrower,
and O.S.I. Puerto Rico, as a Borrower, and Lender. The Credit Agreement amends
and restates in its entirety that certain Credit Agreement, dated as of October

Sciences 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 Ocular Sciences and each
other Subsidiary of Ocular Sciences under the Loan Documents, on the terms set
forth herein.

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

                        DEFINITIONS AND ACCOUNTING TERMS

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

                                   ARTICLE II
                         GUARANTY AND RELATED PROVISIONS

                  SECTION 2.1  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 Ocular Sciences or any Subsidiary of Ocular Sciences now
         outstanding or hereafter arising under any of the Loan



                                     B-1-2
<PAGE>   86

         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 2.2 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 Ocular Sciences 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 2.3 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
Ocular Sciences or any Subsidiary of Ocular Sciences 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 Ocular Sciences or any other Guarantor and whether or not Ocular
Sciences 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 Ocular Sciences
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



                                     B-1-3
<PAGE>   87

enforce any Lien or to apply any proceeds thereof; (v) any change, restructuring
or termination of the corporate structure or existence of Ocular Sciences 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 2.4 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 Ocular Sciences
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 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 Ocular
         Sciences 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;



                                     B-1-4
<PAGE>   88

                  (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 Ocular Sciences, Lender, any
         endorser or creditor of Ocular Sciences 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 Ocular Sciences
         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 Ocular Sciences 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 Ocular
         Sciences, 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 Ocular Sciences 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.



                                     B-1-5
<PAGE>   89

                  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 2.7 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 Ocular Sciences,
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 Ocular Sciences or,
         except as set forth in Section 2.10, against any other Subsidiary of
         Ocular Sciences 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 Ocular Sciences, 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
         Ocular Sciences 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 2.8 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,



                                     B-1-6
<PAGE>   90

         several or joint and several) of Ocular Sciences or any Subsidiary of
         Ocular Sciences 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 Ocular Sciences 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
         Ocular Sciences or any Subsidiary of Ocular Sciences 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 Ocular Sciences or any Subsidiary of Ocular Sciences 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



                                     B-1-7
<PAGE>   91

         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 Ocular Sciences or any Subsidiary of Ocular Sciences 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 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 2.9 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



                                     B-1-8
<PAGE>   92

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 2.10 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 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 2.11 Joint and Several Obligation. This Guaranty and
all liabilities of each Guarantor hereunder shall be the joint and several
obligation of each Guarantor and



                                     B-1-9
<PAGE>   93

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 3.1 Condition of Ocular Sciences. Each Guarantor is
fully aware of the financial condition of Ocular Sciences and its Subsidiaries
and is executing and delivering this Guaranty based solely upon such Guarantor's

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

of its Subsidiaries and on the authority of all officers, directors and agents
acting or purporting to act on their behalf.

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 Ocular Sciences or any

         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 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.

         Guaranty Taxes by any Guarantor, such Guarantor shall furnish to the

         to this Section 3.8.

                  SECTION 3.9 No Waiver; Remedies. No failure on the part of the

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

                  SECTION 3.10 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

exercised independently of, and in addition to, each other such right, power or
remedy.

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.

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

         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 2.2 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 Guarantor, or (iii) any Bankruptcy, Insolvency or
Liquidation Proceeding is commenced involuntarily against Guarantor and either
(x) remains pending for more than 30 days or (y) an order for relief is granted
or consented to by O.S.I. Puerto Rico or by the debtor therein, then all
liability of 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 2.3 Guaranty Absolute and Unconditional. 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
O.S.I. Puerto Rico or any Subsidiary of O.S.I. Puerto Rico 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 Guarantor under this Guaranty are independent of the Guaranteed Obligations,
and a separate action or actions may be brought and prosecuted against Guarantor
to enforce this Guaranty, whether or not any action is brought against O.S.I.
Puerto Rico or any other guarantor and whether or not O.S.I. Puerto Rico or any
other guarantor is joined in any such action or actions. The liability of
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 O.S.I. Puerto Rico 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

                                     B-2-3


<PAGE>   104
Lien or to apply any proceeds thereof; (v) any change, restructuring or
termination of the corporate structure or existence of O.S.I. Puerto Rico; 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 2.4 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 O.S.I. Puerto Rico
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, Guarantor's liability under this Guaranty shall likewise survive. This
Guaranty may be released only in writing.

                  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 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 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 O.S.I.
         Puerto Rico 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;


                                     B-2-4


<PAGE>   105
                  (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 O.S.I. Puerto Rico, Lender, any
         endorser or creditor of O.S.I. Puerto Rico 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 the 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 O.S.I. Puerto Rico
         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 O.S.I. Puerto Rico 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 O.S.I.
         Puerto Rico, 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 O.S.I. Puerto Rico 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


                                     B-2-5


<PAGE>   106
                  (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 2.7 Subrogation. 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 Guarantor at any time may have against O.S.I. Puerto Rico, 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. 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 O.S.I. Puerto Rico or
         against any other Subsidiary of O.S.I. Puerto Rico, and each such
         agreement now existing or hereafter entered into is and shall be void;

                  (b) Release. Guarantor waives and releases any such right or
         claim against O.S.I. Puerto Rico, any other guarantor or any other such
         Person until the Guaranteed Obligations have been paid in full; and

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

                  SECTION 2.8 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 O.S.I.


                                     B-2-6


<PAGE>   107
         Puerto Rico or any Subsidiary of O.S.I. Puerto Rico now outstanding or
         hereafter incurred or owed to 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, Guarantor will not 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. Guarantor agrees that (i) it will
         not demand, accept or hold any Lien upon any real or personal property
         of O.S.I. Puerto Rico 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 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
         O.S.I. Puerto Rico or any Subsidiary of O.S.I. Puerto Rico 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 O.S.I. Puerto Rico or any Subsidiary of O.S.I. Puerto Rico
         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


                                     B-2-7


<PAGE>   108
         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 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, 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. Guarantor will file all claims
         against O.S.I. Puerto Rico or any Subsidiary of O.S.I. Puerto Rico 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
         Guarantor thereunder. If 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
         Guarantor with full power of substitution, either to file such claim or
         proof thereof in the name of 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.
         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 Guarantor's liability under this Guaranty.

                  SECTION 2.9 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 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

                                     B-2-8


<PAGE>   109
Code or any applicable provision of comparable state law, the liability of
Guarantor under this Guaranty shall be limited to the maximum amount lawful and
not subject to avoidance under such law.

                                   ARTICLE III
                            MISCELLANEOUS PROVISIONS

                  SECTION 3.1 Condition of O.S.I. Puerto Rico. Guarantor is
fully aware of the financial condition of O.S.I. Puerto Rico and is executing
and delivering this Guaranty based solely upon 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. Guarantor represents and
warrants that it is in a position to obtain, and Guarantor hereby assumes full
responsibility for obtaining, any additional information concerning the
financial condition of O.S.I. Puerto Rico and any other matter pertinent hereto
as Guarantor may desire, and Guarantor is not relying upon or expecting the
Lender to furnish to Guarantor any information now or hereafter in the
possession of the Lender concerning the same or any other matter. By executing
this Guaranty, Guarantor knowingly accepts the full range of risks encompassed
within a contract of this type, which risks Guarantor acknowledges. Guarantor
shall not 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 O.S.I. Puerto Rico or any Subsidiary of O.S.I. Puerto Rico, the
ability of O.S.I. Puerto Rico or any Subsidiary of O.S.I. Puerto Rico 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, O.S.I. Puerto Rico, any Subsidiary of O.S.I. Puerto Rico or any
other Person, or any other event, occurrence, condition or circumstance
whatsoever.


                  SECTION 3.2    Amendments.

                  (a) Amendment to Guaranty. No amendment or waiver of any
         provision of this Guaranty, no consent to any departure by 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 Guarantor hereunder, or (ii) postpone any date fixed for
         payment hereunder.

                                     B-2-9


<PAGE>   110
                  (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 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 O.S.I. Puerto Rico, 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 3.3 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 3.4 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 Guarantor against any and all liability of 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 3.5 Successors and Assigns. This Guaranty is binding
upon and enforceable against Guarantor, its successors and assigns, and shall
inure to the benefit of, and be enforceable by, the Lender and its
representatives, successors and assigns.

                                     B-2-10


<PAGE>   111
                  SECTION 3.6 No Inquiry. The Lender may rely, without further
inquiry, on the power and authority of Guarantor, O.S.I. Puerto Rico and on the
authority of all officers, directors and agents acting or purporting to act on
their behalf.

                  SECTION 3.7 Involuntary Proceedings. So long as the Lender is
obligated to extend credit under the Credit Agreement or any Guaranteed
Obligations are outstanding, Guarantor will not, without the prior written
consent of the Lender, commence or join with any other Person in commencing any
Bankruptcy, Insolvency or Liquidation Proceeding against O.S.I. Puerto Rico.

                  SECTION 3.8 Payments Free and Clear of Taxes.

                  (a) Payment. 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. Guarantor hereby indemnifies the Lender for the
         full amount of Guaranty Taxes (including, without limitation, any

Collateral, to enable Secured Party to exercise and enforce its rights and
remedies hereunder with respect to any Collateral, to protect the Collateral

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.

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.

        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

               (c) The Grantor does not do business, and for the previous five

<PAGE>   119
               (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 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, 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) The Pledged Shares are certificated securities evidenced and
        represented by certificates issued in bearer or registered form. All
        originals of all stock certificates and other instruments or investment
        property constituting Collateral 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 be 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.

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


                                   ARTICLE IV
                                    COVENANTS

               SECTION 4.1 Covenants of Grantors. 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 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 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 


                                     B-3-5

        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.


                                    ARTICLE V
                   VOTING RIGHTS, DIVIDENDS AND DISTRIBUTIONS

               SECTION 5.1 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 


                                     B-3-6


<PAGE>   121
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 shall be limited to subsequent notice only, which the
        Grantor shall provide to Secured Party in writing within 5 days after
        such conversion; 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 5.2 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, 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 6.1 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-3-7


<PAGE>   122
               (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.


In addition, each holder of any Secured Obligation 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 6.2 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 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 6.3 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 Grantors shall be
and remain liable for any deficiency.

               SECTION 6.4 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 6.5 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 


                                     B-3-8


<PAGE>   123
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 6.6 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.


                                  ARTICLE VII
                                 SECURED PARTY

               SECTION 7.1 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 VI 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 7.2 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 7.3 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.

of this Agreement or any provision hereof.

               SECTION 8.3 Changes. This Agreement or any provision hereof may
be changed, waived or terminated only by a statement in writing signed by the
party against which such change, waiver or termination is sought to be enforced

specific instance and for the specific purpose for which given.

               SECTION 8.4 Grantor Remains Liable. The Grantor shall remain
liable under all contracts and agreements included in the Collateral to the
extent set forth therein to perform all of its duties and obligations thereunder
to the same extent as if this Agreement had not been executed. The exercise or
enforcement by Secured Party of any of its rights and remedies under this
Agreement or in respect of the Collateral shall not release the Grantor from any
of its duties or obligations under any such contracts or agreements. Secured
Party shall not be obligated to perform any such duties or obligations and shall
not be liable for any breach thereof.

               SECTION 8.5 No Waiver. No failure by Secured Party to exercise,
or delay by Secured Party in exercising, any power, right or remedy under this
Agreement shall operate as a waiver thereof. No waiver by Secured Party shall be
effective unless given in a writing signed by it. No waiver so given shall
operate as a waiver in respect of any other matter or in respect of the same
matter on a future occasion. Acceptance of or acquiescence in a course of
performance in respect of this Agreement shall not waive or affect the
construction or interpretation of the terms of this Agreement even if the
accepting or acquiescing party had knowledge of the nature of the performance
and opportunity for objection.

               SECTION 8.6 Entire Agreement. This Agreement and the other Loan
Documents are intended by the parties as a final expression of their agreement

invalid, illegal or unenforceable in any jurisdiction, the validity, legality
and enforceability of the remaining provisions hereof, or of such provision in
any other application, shall not be in any way affected or impaired thereby and
such other provisions and applications shall be enforceable to the full extent
lawful.

               SECTION 8.8 Power of Attorney. Each Grantor hereby appoints and
constitutes Secured Party or any delegate, nominee or agent acting for Secured
Party as the 


                                     B-3-10

has failed to do so, and (z) take any action reasonably necessary to any of the
foregoing. This power of attorney is coupled with an interest and is irrevocable
as to the Grantor. Secured Party shall have no duty whatsoever to exercise any
power herein granted it.

               SECTION 8.9 Counterparts. This Agreement and any amendments,
waivers, consents or supplements may be executed in any number of counterparts,
each of which when so executed and delivered shall be deemed an original, but
all of which shall together constitute one and the same agreement.

               SECTION 8.10 Costs and Expenses. The Grantor hereby agrees to pay
or reimburse Secured Party for all reasonable costs and expenses (including,
without limitation, reasonable attorneys' fees and disbursements and court

Attn:  Ms. Lori S. Edwards

        RE:  OCULAR SCIENCES, INC. AND OCULAR SCIENCES PUERTO RICO, INC.

Ladies and Gentlemen:

        We have acted as special counsel for Ocular Sciences, Inc., a Delaware
corporation ("Ocular Sciences"), and Ocular Sciences Puerto Rico, Inc. ("O.S.I.
Puerto Rico") (collectively the "Borrowers"), in connection with that certain
Amended and Restated Credit Agreement dated as of even date herewith, including
all exhibits and schedules thereto (the "Credit Agreement") by and between the
Borrowers and Comerica Bank-California, a California chartered bank ("Lender").
We are rendering this opinion pursuant to Section 3.1(f) of the Credit
Agreement. Except as otherwise defined herein, capitalized terms used but not
defined herein shall have the meanings given to them in the Credit Agreement.

        In connection with this opinion, we have examined the following
documents (the items referred to in clauses 1 through 6 below are referenced to
herein as the "Loan Documents"):

        1.      The Credit Agreement;

        2.      The Amended and Restated Subsidiary Guaranty (the "Subsidiary
                Guaranty");

        3.      The Amended and Restated Pledge Agreement (the "Pledge
                Agreement");

        4.      The Parent Guaranty;

        5.      A UCC-2 financing statement for filing with the Secretary of
                State of California naming Ocular Sciences as the debtor and the
                Lender as the secured party (the "Financing Statement");

        6.      Assignments Separate From Certificates evidencing the Pledged
                Shares;


                                      C-1-1


<PAGE>   134

        7.      Certificate of Incorporation and Bylaws of Ocular Sciences and
                O.S.I. Puerto Rico, certified by the Secretary of Ocular
                Sciences and O.S.I. Puerto Rico, respectively; and

        8.      An officer's certificate of Ocular Sciences, a copy of which is
                attached as Exhibit A hereto ("Ocular Sciences' Certificate"),
                and an officer's certificate of O.S.I. Puerto Rico, a copy of
                which is attached as Exhibit B hereto ("O.S.I. Puerto Rico's
                Certificate").

        In addition, we have examined and relied upon originals or copies
certified to our satisfaction of such records, documents, certificates,
opinions, memoranda and other instruments as in our judgment are necessary or
appropriate to enable us to render the opinions expressed below, including the
Ocular Sciences' Certificate and O.S.I. Puerto Rico's Certificate.

        We are admitted to practice law only in the State of California, and we
express no opinion concerning any law other than the law of the State of
California, the Delaware General Corporation Law, and the law of the United
States of America.

        In rendering this opinion, we have assumed the genuineness and
authenticity of all signatures (other than that of Ocular Sciences and O.S.I.
Puerto Rico) on original documents; that all natural persons who are signatories
are legally competent to execute and deliver such documents; the authenticity
and completeness of all documents submitted to us as originals; the conformity
of originals to all documents submitted to us as copies; the accuracy,
completeness and authenticity of certificates of public officials; the due
authorization, execution and delivery of all documents (except the due
authorization, execution and delivery by Ocular Sciences and O.S.I. Puerto Rico
of the Loan Documents to which they respectively are parties) where
authorization, execution and delivery are prerequisites to the effectiveness of
such documents; the power and authority of the Lender to enter into and perform
their obligations under the Loan Documents; that each of the Loan Documents has
been duly executed by the Lender and delivered to Ocular Sciences and O.S.I.
Puerto Rico and is the legal, valid and binding obligation of the Lender,
enforceable against the Lender in accordance with their terms; that the Lender
is duly qualified in the State of California to do business of the type
contemplated by the Loan Documents; 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; 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 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


                                      C-1-2

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;
that except for the Loan Documents, there are no documents or agreements between
the parties which would expand or otherwise modify the respective rights and
obligations of the parties set forth in the Loan Documents; and with respect to
matters of fact (as distinguished from matters of law), with your permission and
without verification by us, we also have relied upon and assumed that the
representations of Ocular Sciences, O.S.I. Puerto Rico and the other parties set
forth in the Loan Documents, the Ocular Sciences' Certificate, O.S.I. Puerto
Rico's Certificate and any other certificates, instruments or agreements
executed in connection therewith or delivered to us are true, correct, complete
and not misleading. We have made no independent investigation of any such facts
stated in any such certificate or representation.

        Where we render an opinion "to the best of our knowledge" or concerning
an item "known to us" or our opinion otherwise refers to our knowledge, it is
intended to indicate that during the course of our representation of Ocular
Sciences and O.S.I. Puerto Rico in connection with the Loan Documents, no
information that would give us current actual knowledge of the inaccuracy of
such statement has come to the attention of those attorneys in this firm who
have rendered or are rendering legal services to Ocular Sciences and O.S.I.
Puerto Rico in connection with the Loan Documents. However, except as otherwise
expressly indicated, we have not undertaken any independent investigation to
determine the accuracy of such statement and any limited inquiry undertaken by
us during the preparation of this opinion letter should not be regarded as such
an investigation; 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 Ocular Sciences and O.S.I. Puerto Rico.

        With respect to our opinion in paragraph 4 below, we have relied solely
upon copies, supplied to us by Ocular Sciences, of those undertakings,
contracts, indentures, mortgages, deeds of trust or other instruments, documents
or agreements which have been identified to us by Ocular Sciences in the Ocular
Sciences' Certificate as all material undertakings, contracts, indentures,
mortgages, deeds of trust or other instruments, documents or agreements to which
Ocular Sciences is a party or by which it is bound (the "Ocular Sciences
Material Contracts"). We have not undertaken any independent investigation of
such matters, other than the inquiries we have made of the officers of Ocular
Sciences and the review we have made of the corporate records of Ocular Sciences
described above.

        With respect to our opinion in paragraph 5 below, we have relied solely
upon copies, supplied to us by O.S.I. Puerto Rico, of those undertakings,
contracts,


                                      C-1-3

indentures, mortgages, deeds of trust or other instruments, documents or
agreements which have been identified to us by O.S.I. Puerto Rico in O.S.I.
Puerto Rico's Certificate as all material undertakings, contracts, indentures,
mortgages, deeds of trust or other instruments, documents or agreements to which
O.S.I. Puerto Rico is a party or by which it is bound (the "O.S.I. Puerto Rico
Material Contracts"). We have not undertaken any independent investigation of
such matters, other than the inquiries we have made of the officers of O.S.I.
Puerto Rico and the review we have made of the corporate records of O.S.I.
Puerto Rico described above.

        In rendering our opinion in the second and last sentences of paragraph
1, we have relied solely on a certificate of good standing from each of the
Secretary of State's office of each of the states specified in that paragraph.

        On the basis of the foregoing, and subject to the qualifications stated
below, we are of the opinion that:

        1. Ocular Sciences is a corporation, duly incorporated and validly
existing under the laws of Delaware and has the requisite corporate power and
authority to own its property and to conduct the business in which it is
currently engaged. Ocular Sciences is duly qualified and in good standing as a
foreign corporation authorized to transact business in California and in each of
the states listed below its name on Exhibit C. O.S.I. Puerto Rico is a
corporation, duly incorporated and validly existing under the laws of Delaware
and has the requisite corporate power and authority. O.S.I. Puerto Rico is duly
qualified and in good standing as a foreign corporation authorized to transact
business in California and in each of the states listed below its name on
Exhibit C.

        2. Ocular Sciences and O.S.I. Puerto Rico have taken all necessary and
appropriate corporate action to authorize the execution, delivery and
performance of the Loan Documents to which they respectively are parties, and
each has the corporate power and authority to execute, deliver and perform the
Loan Documents to which it is respectively a party.

        3. The Credit Agreement, the Pledge Agreement and the Parent Guaranty
have been duly executed and delivered by Ocular Sciences. The Credit Agreement
and the Subsidiary Guaranty have been duly executed and delivered by O.S.I.
Puerto Rico. The Credit Agreement, the Pledge Agreement, and the Parent Guaranty
constitute the legal, valid and binding obligations of Ocular Sciences,
enforceable against Ocular Sciences in accordance with their respective terms.
The Credit Agreement and the Subsidiary Guaranty constitute the legal, valid and
binding

Comerica Bank-California

obligations of O.S.I. Puerto Rico, enforceable against O.S.I. Puerto Rico in
accordance with their respective terms.

        4. The execution, delivery and performance by Ocular Sciences of the
Loan Documents to which it is a party do not (a) to the best of our knowledge,
violate or contravene any order of any court or United States or California
governmental agency as presently in effect applicable to Ocular Sciences; (b)
violate or contravene any United States or California law presently in effect
and applicable to Ocular Sciences; (c) conflict with or result in a breach of or
constitute a default under the Certificate of Incorporation or Bylaws of Ocular
Sciences; (d) to the best of our knowledge, violate or result in a breach of or
constitute any default under any of the Ocular Sciences Material Contracts; and
(e) result in or require the creation or imposition of any lien on any of Ocular
Sciences' properties pursuant to any order of any court or United States or
California governmental agency as presently in effect applicable to Ocular
Sciences or any of the Ocular Sciences Material Contracts, other than the liens
created pursuant to the Loan Documents.

        5. The execution, delivery and performance by O.S.I. Puerto Rico of the
Loan Documents to which it is a party do not (a) to the best of our knowledge,
violate or contravene any order of any court or United States or California
governmental agency as presently in effect applicable to O.S.I. Puerto Rico; (b)
violate or contravene any United States or California law presently in effect
and applicable to O.S.I. Puerto Rico; (c) conflict with, or result in a breach
of, or constitute a default under the Certificate of Incorporation or Bylaws of
O.S.I. Puerto Rico; (d) to the best of our knowledge, violate or result in a
breach of, or constitute any default under, any of the O.S.I. Puerto Rico
Material Contracts; and (e) result in, or require the creation or imposition of,
any lien on any of O.S.I. Puerto Rico's properties pursuant to any order of any
court or United States or California governmental agency as presently in effect
applicable to O.S.I. Puerto Rico or any of the O.S.I. Puerto Rico Material
Contracts, other than the liens created pursuant to the Loan Documents.

        6. No authorization, consent, approval, license, qualification or formal
exemption from, nor notice to, nor any filing, recordation, declaration or
registration with, any United States or California governmental authority is
necessary or required on the part of Ocular Sciences or O.S.I. Puerto Rico in
connection with the execution, delivery, or performance by Ocular Sciences or
O.S.I. Puerto Rico of the Loan Documents to which they respectively are parties,
except for such filings or recordations as may be necessary to perfect the
security interests or liens granted by the Loan Documents.

        7. To the best of our knowledge, there is no action, suit or proceeding
at law or in equity by or before any court or governmental agency now pending
against Ocular Sciences with respect to the Loan Documents to which it is a
party.

        8. To the best of our knowledge, there is no action, suit or proceeding
at law or in equity by or before any court or governmental agency threatened
against O.S.I. Puerto Rico with respect to the Loan Documents to which it is a
party.

        9. The delivery to the Lender of (a) the original stock certificates
evidencing the Pledged Shares (as defined in the Pledge Agreement), and (b) the
duly executed Assignments, in blank, and the Lender's continuous possession of
such documents, perfects the Lender's security interest in the Pledged Shares.
Upon the due execution by Ocular Sciences and the proper filing of the Financing
Statement in the Office of the Secretary of State of California (assuming that
the representations made by Ocular Sciences and by O.S.I. Puerto Rico 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 Ocular Sciences under the Pledge Agreement in and to such Collateral
to secure the Secured Obligations (as defined in the Pledge Agreement) 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 ("CUCC"). Except for
the filing of periodic continuation statements, it is not necessary under the
CUCC to re-record, re-register or refile a UCC-1 financing statement, or to
record, register or file any other or additional documents, instruments or
statements in order to maintain perfection of the security interests in any such
Collateral granted in favor of the Lender, except that additional financing
statements may be required to be filed if Ocular Sciences or O.S.I. Puerto Rico
changes its name, identity or corporate structure so as to make a financing
statement seriously misleading (unless new appropriate financing statements
indicating the new name, identity or corporate structure are duly filed), or if
there is any change in the location of its chief executive office or chief place
of business or the state in which any of the Collateral is located.

        10. Neither Ocular Sciences 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.

        11. To the best of our knowledge, neither Ocular Sciences nor O.S.I.
Puerto Rico is generally engaged in the business of purchasing or selling margin
stock (within the meaning of Regulation G of the Board of Governors of the
Federal Reserve System) or extending credit for the purpose of purchasing or
carrying margin stock. To the best of our knowledge, no proceeds of any Advance
will be

used for any purpose that requires any Lender to deliver or obtain any
certification under, or to comply with any margin requirements or other
provision of, Regulations G, T, V or X of the Board of Governors of the Federal
Reserve System.

        The opinions expressed in this letter are subject to the following
qualifications:

                                                    BBH NO. 80.7

Ladies and Gentlemen:

     We have acted as counsel to Ocular Sciences Puerto Rico, Inc., formerly
known as O.S.I. Puerto Rico Corporation, a Delaware corporation ('O.S.I. Puerto
Rico'), in connection with the Amended and Restated Credit Agreement by and
between Ocular Sciences, Inc., a Delaware corporation previously known as O.S.I.
Corporation, a California corporation ('Ocular Sciences') and O.S.I. Puerto
Rico, as Borrowers and Comerica Bank-California (the "Lender") as lender, dated
as of November 7, 1997 (the 'Credit Agreement'). This opinion is delivered to
you pursuant to the provisions of Section 3.1(f) of Article III of the Credit
Agreement (the 'Credit Agreement'). Except as otherwise defined herein,
capitalized terms shall have the respective meanings given to them in the Credit
Agreement.

     In connection with this opinion, we have examined the following documents,
each dated as of November 7, 1997, unless otherwise noted (collectively, the
"Loan Documents"):

     1.   The Amended and Restated Credit Agreement by and between
<PAGE>   144
Comerica Bank-California
November 7, 1997
Page - 2 - 

          Ocular Sciences, O.S.I. Puerto Rico, and the Lender;

     2.   The Parent Guaranty between Ocular Sciences and the Lender (the
          'Parent Guaranty');

     3.   The Amended and Restated Pledge Agreement by and between Ocular
          Sciences, Inc. and the Lender;

     4.   The Amended and restated Subsidiary Guaranty between O.S.I. Puerto
          Rico and the Lender (the 'Subsidiary Agreement');

     5.   The Certificate of Incorporation and By-Laws of O.S.I. Puerto Rico;
          and

     6.   Such other agreements, corporate records and documents, including
          originals, or copies, certified or otherwise, identified to our
          satisfaction of such certificates of public officials and of officers
          and representatives of O.S.I. Puerto Rico as we have deemed necessary
          as a basis for the opinions hereinafter expressed.

     In addition, as to certain matters, we have relied upon certificates and
advice from various public officials. We assume the accuracy of all material and
factual matters contained therein, which are not independently established. We
have also examined, and as to matters of fact, relied upon the representations
and warranties set forth in the Credit Agreement and certificates delivered
pursuant thereto. We have assumed the due authorization, execution and delivery
of the Loan Documents and other documents executed and delivered by O.S.I.
Puerto Rico and Ocular Sciences, and by all other parties thereto other than
said entities.

     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.  The courts of the Commonwealth of Puerto Rico would observe and give
effect to the choice of California law as the governing law of the Credit
Agreement and the Subsidiary Agreement.

     2.  The United States District Court in the Commonwealth of Puerto Rico
would enforce a judgment obtained in a United States federal court in California
with respect to O.S.I. Puerto Rico and its obligations under the Credit
Agreement, as a Borrower, and under the Subsidiary Guaranty, as a Guarantor. In
the case of a judgment rendered by a California state court, for 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.  O.S.I. 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 O.S.I. 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 O.S.I. Puerto Rico, except that (i) the rights of the Lender under
this letter shall benefit any permitted successors, assigns and participants of
the Lender, and (ii) copies of this letter may be shown to or delivered to (A)
any regulatory or supervisory authority having jurisdiction over the Lender and
its successors and assigns, and (B) to the Lender's and its successors and
assigns' accountants, auditors and attorneys.

     We are qualified to practice law in the Commonwealth of Puerto Rico and do
not purport to be experts on, or express any opinion herein concerning any law
other than the laws of the Commonwealth of Puerto Rico. In rendering the
foregoing opinions we have made no independent investigation of any laws other
than the laws of the

this Section 6.

   7.   COMPANY LOAN(S) TO EMPLOYEE. 

        7.1     $450,000 LOAN UPON PURCHASE OF NEW RESIDENCE. Upon Employee's
purchase of the New Residence, the Company will provide Employee with an
interest free loan of Four Hundred Fifty Thousand Dollars ($450,000) (the
"$450,000 Loan"). The $450,000 Loan shall be secured by a deed of trust (the
$450,000 Deed of Trust") on the New Residence and by a security interest in the
Options and any shares issued upon exercise of the Options (the "Underlying
Securities"). The $450,000 Deed of Trust shall be subordinate to any deed of
trust Employee grants on the New Residence to a bank or other financial
institution for a loan to purchase the New Residence. Employee will be
prohibited from selling, transferring or otherwise disposing of any interest in
the New Residence, the Options or the Underlying Securities while any
obligations are outstanding under the $450,000 Loan. The $450,000 Loan shall be
due and payable in full on the earlier of: (i) 5 years from the Effective date;
(ii) 6 months after Employee's voluntary resignation or termination by the
Company for Cause, (iii) Employee's default under any loan secured by the New
Residence or (iv) the sale, transfer or other disposition of the New Residence.
Notwithstanding the foregoing, the $450,000 Loan shall be forgiven if Employee
remains continuously employed by the Company from the date hereof through
October 15, 2000. In the event that any portion of principal of the $450,000
Loan is paid by Employee and Employee subsequently becomes entitled to
forgiveness of the $450,000 Loan pursuant to the preceding sentence, then the
amount of principal paid by the Employee shall be returned to him. Employee
shall be responsible for all taxes arising from any loan forgiveness and the
Company will be entitled to withhold appropriate amounts for tax purposes.

        7.2     POSSIBLE ADDITIONAL LOANS. If Employee is unable to sell the
Old residence prior to the purchase of the New Residence, then the Company will
either (i) arrange

                                       3
<PAGE>   4
for a bank or other financial institution to provide Employee with a loan in
the amount of the purchase price of the New Residence less $450,000 or (ii)
loan such amount to Employee itself, each up to a maximum of $1,100,000. Any
obligation taken on by the Company in connection with such loan (e.g., a
guarantee) or any amount so loaned by the Company, shall be released or paid,
as the case may be, on the earlier of (i) six months after the date of the loan
or (ii) the date the $450,000 Loan is due. Any such loan will be on standard
terms for similar loans and will include a first deed of trust on the New
Residence. Employee will enter into any documentation reasonably requested by
the Company to support any guaranty provided by the Company pursuant to this
Section 7.2

        7.3     OTHER LOAN TERMS. In connection with the loans set forth in
Section 7.1 and 7.2 above (the "Loans") Employee and Employee's spouse shall
execute any documents reasonably requested by the Company or the institution
granting the Loans, including loan and security agreements, promissory notes
and deeds of trust. Such documents shall have such other terms and provisions
as are typical for residential loans, including standard default provisions and
a provision regarding the payment of fees and expenses, including reasonable
attorneys' fees, incurred enforcing or collecting the Loans.

   8.   PROPRIETARY RIGHTS. Employee hereby agrees to execute an Employee 
Invention Assignment and Confidentiality Agreement with the Company in
substantially the form attached hereto as Exhibit A.

   9.   TERMINATION.

        9.1     EVENTS OF TERMINATION. Employees employment with the Company

Without Cause"); or

                (c)     the effective date of Employee's voluntary termination
of his employment with the Company ("Voluntary Termination").

          10.2  TERMINATION WITHOUT CAUSE. In the event of any termination of

     11.  NON-SOLICITATION.  So long as Employee is an employee of the Company
and for one (1) year thereafter, Employee shall not, directly or indirectly,
either for himself or for any other person or entity, directly or indirectly,
solicit, induce or assist another to solicit or induce 

                                       5
<PAGE>   6
any employee, consultant, customer or supplier of the Company to terminate his,
her or its relationship with the Company.

        12.     MISCELLANEOUS.

                12.1    ARBITRATION. Employee and the Company agree to submit to
mandatory binding arbitration any controversy or claim arising out of, or
relating to, this Agreement or any breach hereof, provided, however, that the
Company retains its right to, and shall not be prohibited, limited or in any
other way restricted from, seeking or obtaining equitable relief from a court
having jurisdiction over the parties. Such arbitration shall be conducted in
accordance with the commercial arbitration rules of the American Arbitration
Association in effect at that time, and judgment upon the determination or
award rendered by the arbitrator may be entered in any court having
jurisdiction thereof.

                12.2    SEVERABILITY.  If any provision of this Agreement shall
be found by any arbitrator or court of competent jurisdiction to be invalid or
unenforceable, then the parties hereby waive such provision to the extent that
it is found to be invalid or unenforceable and to the extent that to do so
would not deprive one of the parties of the substantial benefit of its bargain.
Such provision shall, to the extent allowable by law and the preceding
sentence, be modified by such arbitrator or court to effect the intent of the
parties to the extent possible, and as modified, shall be enforced as any other
provision hereof, all the other provisions continuing in full force and effect.

                12.3    NO WAIVER.  The failure by either party at any time to
require performance or compliance by the other of any of its obligations or
agreements shall in no way affect the right to require such performance or
compliance at any time thereafter. The waiver by either party of a breach of any
provision hereof shall not be taken or held to be a waiver of any preceding or
succeeding breach of such provision or as a waiver of the provision itself. No
waiver of any kind shall be effective or binding, unless it is in writing and is
signed by the party against whom such waiver is sought to be enforced.

                12.4    ASSIGNMENT.  This Agreement and all rights hereunder
are personal to Employee and may not be transferred or assigned by Employee
at any time. The Company may assign its rights, together with its obligation
hereunder, to any parent or successor, or in connection with any sale,
transfer or other disposition of all or substantially all of its business
and/or assets, provided, however, that any such assignee assumes the Company's
obligations hereunder.

                12.5    WITHHOLDING.  All sums payable to Employee hereunder
shall be reduced by all federal, state, local and other withholding and similar
taxes and payments required by applicable law.

                12.6    ENTIRE AGREEMENT.  This Agreement constitutes the
entire and only agreement between the parties relating to the subject matter
hereof, and this Agreement supersedes and cancels any and all previous
contracts, arrangements or understandings with respect thereto.
