ITEM 1.  BUSINESS

GENERAL DEVELOPMENT OF BUSINESS

STATEMENT UNDER THE PRIVATE SECURITIES LITIGATION REFORM ACT

    The statements in this 10-K that relate to future plans, events or
performance are forward-looking statements that involve risks and uncertainties.
Actual results, events and performance may differ materially. Readers are
cautioned not to place undue reliance on these forward-looking statements, which
speak only as of the date hereof. Coherent undertakes no obligation to release
publicly the result of any revisions to these forward-looking statements that
may be made to reflect events or circumstances after the date hereof or to
reflect the occurrence of unanticipated events.

RISK FACTORS

    COMPETITIVE ENVIRONMENT.  Coherent is one of the largest companies in each
of its business segments. No single competitor offers as wide a range of
products as are manufactured and sold by Coherent. However, competition is
intense in all business segments because there are a number of smaller and
larger companies selling products which compete directly with one or more
Coherent products.

    Coherent's competitors are numerous, ranging from some of the world's
largest corporations to many relatively small and highly specialized firms.
Major competitors in Coherent's respective market segments include, but are not
limited to, the following list of companies: the Electro-Optics segment competes
primarily against Spectra-Physics Lasers, Inc., SDL, Inc., Rofin Sinar
Technologies, Inc., Continuum (a division of Hoya), Excel Technology, Inc.,
II-VI Inc., Optical Coating Labs, II-VI, and Newport Corporation. The Medical
segment's direct competition includes, but is not limited to ESC Medical
Systems Ltd., Candela Corporation, Cynosure, Laser Scope, The Carl Zeiss Group,
Nidek, HGM Medical, and IRIDEX Corporation. The Lambda segment's main
competitors include Cymer, Inc., Komatsu, Ltd., Ushio, Lumonics, SOPRA,
Continuum, and Spectra-Physics Lasers, Inc.

    The markets in which Coherent is engaged are subject to keen competition and
rapid technological change. The principal factors of competition for all
products are performance, reliability, price, service, marketing and
distribution, technological achievement and human resources.

    A failure to remain competitive in these markets could cause a loss of
market share, declining growth, and the inability to manage inventories if
competitors gain increased market acceptance for their products. Some of the
competitors are larger than Coherent and have a greater access to capital,
technical, marketing, sales and other resources than does Coherent.

    In addition, there can be no assurance that Coherent's current or potential
competitors will develop or acquire comparable or superior products to those
developed by Coherent. Any possible business combinations or mergers by
competitors, forming a larger, more significant competitor, could result in
increased competition, price reductions, reduced margins, or loss of market
share, any of which could materially and adversely affect Coherent's businesses,
operating results, and financial condition.

    NEW PRODUCT INTRODUCTIONS.  Coherent's future operating results are
dependent on its ability to rapidly develop, manufacture and market
technologically innovative products that meet customers' needs. In addition,
after the products are developed, Coherent must quickly manufacture such
products in sufficient volumes at acceptable costs to meet demand. Without the
introduction of new products and product enhancements, Coherent's general
product offerings are likely to become technologically obsolete. There can be no
assurance that such new products, if and when introduced, will receive market
acceptance.

    INTERNATIONAL SALES.  Coherent conducts a significant portion of its
business internationally. International sales accounted for 58% and 55% of
Coherent's sales for fiscal 1999 and 1998, respectively. Coherent expects that
international sales will continue to account for a significant portion of its
net sales in the future. A significant amount of these sales occur through its
international subsidiaries (some of which

                                       2
<PAGE>
also perform research, development, manufacturing and service functions) and
from exports from its U.S. operations. As a result, Coherent's international
sales and operations are subject to the risks of conducting business
internationally. Risks include fluctuation in foreign exchange rates, which
could affect the sales price in local currencies of products in foreign markets
as well as the local costs and expenses of foreign operations. Coherent uses
forward exchange, currency swap contracts, currency options and other risk
management techniques, to hedge its exposure to currency fluctuations relating
to its intercompany transactions and certain firm foreign currency commitments;
however, its international subsidiaries remain exposed to the economic risks of
foreign currency fluctuations. There can be no assurance that such factors will
not adversely impact Coherent's operations in the future or require it to modify
current business practices.

    ASIA-PACIFIC.  Recent economic trends in the Asia-Pacific marketplace have
caused a heightened awareness of the impact this portion of the world's economy
can have on the overall economy. The Asia-Pacific market currently represents
almost one-third of the worlds buying power and approximately 26% and 24% of
Coherent's fiscal 1999 and 1998 sales, respectively, are to this region. Changes
in this area's economic growth rate may impact suppliers of product into that
market. While the actual magnitude of the business at risk is unknown, it is
possible that a decrease in capital spending in this market could have an
adverse impact on Coherent's sales and results of operations.

    QUARTERLY FLUCTUATIONS IN OPERATING RESULTS.  A variety of factors may cause
period-to-period fluctuations in the operating results of Coherent. Such factors
include, but are not limited to, product mix, competitive pricing pressures,
material costs, revenue and expenses related to new products and enhancements of
existing product, as well as delays in customer purchases in anticipation of the
introduction of new products or product enhancements by Coherent or its
competitors. The majority of Coherent's revenues in each quarter results from
orders received in that quarter. As a result, Coherent establishes its
production, inventory and operating expenditure levels based on anticipated
revenue levels. Thus, if sales do not occur when expected, expenditure levels
could be disproportionately high and operating results for that quarter, and
potentially future quarters, would be adversely affected.

    VOLATILITY OF STOCK PRICE.  The market price of Coherent's common stock may
be affected by quarterly fluctuations in Coherent's operating results,
announcements by Coherent or its competitors of technological innovations or new
product introductions and other factors. If revenue or earnings in any quarter
fail to meet expectations of the investment community, there could be an
immediate impact on Coherent's stock price. In addition, the stock market has
from time to time experienced extreme price and volume fluctuations,
particularly among stocks of high technology companies, which, on occasion, have
been unrelated to the operating performance of particular companies. Factors not
directly related to Coherent's performance, such as negative industry reports or
disappointing earnings announcements by publicly traded competitors, may have an
adverse impact on the market price of Coherent's common stock. See Item 5,
"Market for the Registrant's Common Equity and Related Stockholder Matters".

    PATENTS AND LICENSES.  The laser industry is characterized by frequent
litigation regarding patent and other intellectual property rights. Because
patent applications are maintained in secrecy in the United States until such
patents are issued and are maintained in secrecy for a period of time outside
the United States, Coherent can conduct only limited searches to determine
whether its technology infringes any patents or patent applications. Any claims
for patent infringement could be time-consuming, result in costly litigation,
divert technical and management personnel, cause shipment delays, require
Coherent to develop non-infringing technology or to enter into royalty or
licensing agreements. Although patent and intellectual property disputes in the
laser industry have often been settled through licensing or similar
arrangements, costs associated with such arrangements may be substantial and
often require the payment of ongoing royalties. These payments could have a
negative impact on gross margins. There can be no assurance that necessary
licenses would be available to Coherent on satisfactory terms, or Coherent could
redesign its products or processes to avoid infringement. Accordingly, an
adverse determination in a

                                       3
<PAGE>
judicial or administrative proceeding or failure to obtain necessary licenses
could prevent Coherent from manufacturing and selling some of its products. This
could have a material adverse effect on Coherent's business, results of
operations and financial condition. Conversely, costly and time consuming
litigation may be necessary to enforce patents issued to Coherent 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.

    Coherent has a significant number of U.S. and foreign technology patents
incorporated into its products. Coherent believes it owns or has the right to
use the basic patents covering its products.

    REIMBURSEMENT.  A significant portion of Coherent's medical products are
purchased by doctors, clinics, hospitals and other users, which bill various
third-party payors, such as governmental programs and private insurance plans,
for covered health care services provided to their patients. Third-party payors
are increasingly scrutinizing whether to cover new products and the level of
reimbursement for covered products used for these health care services. While
Coherent believes that the laser procedures using its products (except for most
aesthetic applications, which comprise approximately half of the Medical
segment's revenue) have generally been reimbursed, payors may deny coverage and
reimbursement for Coherent's products if they determine that the device was not
reasonable and necessary for the purpose for which used or was investigational
or not cost-effective. Failure by doctors, clinics, hospitals and other users of
Coherent's products to obtain adequate reimbursement for use of Coherent's
products from third-party payors, and/or changes in government legislation or
regulation or in private third-party payors' policies toward reimbursement for
procedures employing Coherent's products could have a material adverse effect on
Coherent's business, results of operations and financial condition. Moreover,
Coherent is unable to predict what legislation or regulation, if any, relating
to the health care industry or third-party coverage and reimbursement may be
enacted in the future, or what effect such legislation or regulation may have on
the Company.

    EARTHQUAKES.  A substantial portion of Coherent's research and development
activities, manufacturing, its corporate headquarters and other critical
business operations are located near major earthquake faults. Operating results
could be materially affected in the event of an earthquake or other natural
disaster.

    PRODUCTION AND SOURCES AND AVAILABILITY OF MATERIALS.  Coherent's production
operations consist primarily of assembling and testing its products, although
Coherent manufactures substantially all of its own laser tubes, optics and diode
wafers. Coherent depends upon outside suppliers for most product components,
many of which are manufactured to Coherent's specifications. Coherent maintains
a diverse supplier base, and as a result, typically no individual supplier makes
up more than 5% of total purchases. Coherent has not experienced any significant
difficulty in obtaining raw materials or components in the past. There is always
a possibility of periodic, short-term disruption in supplies of critical, high
technology components.

    RESEARCH AND DEVELOPMENT.  Coherent maintains separate research and
development staffs in all of its operating segments. Development of new and
improved Electro-Optical, Lambda and Medical products is primarily the respon
sibility of engineering department and applications staffs located in the U.S.,
Germany, Finland and the United Kingdom. Such engineering staffs design and
develop both new products and enhancements to existing products. Coherent works
closely with customers, both individually and through Company sponsored
seminars, to develop products to meet customer application and performance
needs.

    Coherent operates in an industry which is subject to rapid technological
change. Its ability to compete and operate successfully depends upon, among
other things, its ability to react to such change. Accordingly, Coherent is
committed to the development of new products as well as the improvement and
refinement of existing products. Fiscal 1999 expenditures for research and
development were $46,759,000, 10% of sales,

                                       4
<PAGE>
compared to $44,534,000, 11% of sales, and $39,406,000, 10% of sales, during
fiscal 1998 and 1997, respectively.

    IMPACT OF ENVIRONMENTAL REGULATION.  Coherent believes that compliance with
federal, state and local environmental protection regulations will not have a
material adverse effect on the capital expenditures, earn ings, competitive and
financial position of Coherent. Coherent is a respondent under Remedial Action
Orders issued by the California Department of Toxic Substance Control relating
to an investigation and remediation of soil and groundwater contamination at its
former facility in the Stanford Industrial Park, Palo Alto, California. See
Note 12, "Commitments and Contingencies", of the Notes to Consolidated Financial
Statements.

    IMPACT OF MEDICAL DEVICE REGULATIONS.  Coherent's medical products are
subject to regulation and control by the Center for Devices and Radiological
Health, a branch of the Food and Drug Administration (FDA) within the Department
of Health and Human Services. Pursuant to the 1976 Medical Device Amendments to
the Federal Food, Drug and Cosmetic Act, and the regulations promulgated
thereunder, the FDA regulates the clinical testing, manufacture, labeling, sale,
distribution and promotion of medical devices. Before a new device can be
introduced into the market, the manufacturer must obtain market clearance
through either the 510(k) premarket notification process or the lengthier
premarket approval ("PMA") application process. Compliance with this process is
expensive and time-consuming. Noncompliance with applicable requirements,
including good manufacturing practices ("GMP") can result in, among other
things, fines, injunctions, civil penalties, recall or seizure of products,
total or partial suspension of production, failure of the government to grant
premarket clearance or premarket approval for devices, withdrawal of marketing
approvals and criminal prosecution. The FDA also has the authority to request
repair, replacement or refund of the cost of any medical device manufactured or
distributed by Coherent. Coherent's medical products are subject to similar
regulations in its major international markets. Complying with these regulations
is necessary for Coherent's strategy of expanding the markets for and sales of
its products into these countries.

    These approvals may include clinical testing, limitations on the number of
sales, controls of end user purchase price and the extent of product
commercialization. In certain instances, these constraints can delay planned
shipment schedules as design and engineering modifications are made in response
to regulatory concerns and requests. Coherent's competitors in the medical field
are subject to the same regulations.

    Coherent believes that its long established working relationship with the
medical community and the high quality of its products allow it to work
effectively within these regulatory constraints.

    EMPLOYEES.  At October 2, 1999, Coherent employed 2,417 persons. Coherent's
continued success will depend in large measure on its ability to attract and
retain highly skilled employees, who are in great demand, particularly in the
Silicon Valley of California, where the Company is based.

THE LASER COMPANY

    Coherent, Inc., a Delaware corporation, (herein referred to as "Coherent" or
"Company") is a global leader in the design, manufacture and sales of lasers,
laser systems, precision optics and related accessories. Coherent integrates
these technologies into a wide variety of products and systems designed to meet
the productivity and performance needs of its customers. Major markets include
the scientific research community, medical institutions, clinics and private
practices, and commercial/OEM (original equipment manufacturer) applications
ranging from semiconductor processing and disk mastering to light shows and
entertainment. Coherent also produces and sells optical and laser components to
other laser system manufacturers.

    The word "laser" is the acronym for "light amplification by stimulated
emission of radiation." Energy is amplified to extremely high intensity by an
atomic process called stimulated emission. The term

                                       5
<PAGE>
"radiation" is often misinterpreted because the term is also used to describe
radioactive materials or ionizing radiation. The use of the word in this
context, however, refers to an energy transfer. Energy moves from one location
to another by conduction, convection, and radiation. The color of laser light is
normally expressed in terms of the laser's wavelength. The most common unit in
expressing a laser's wavelength is a nanometer ("nm"). There are one billion
nanometers in one meter.

    A laser uses a source of energy such as electricity, light or a chemical
reaction to excite electrons in a "lasing medium." When these excited electrons
return to their grounded or normal state, energy is emitted in the form of light
at one or a few specific wavelengths. The lasing medium can be gasses such as
CO(2) or argon, liquid dyes, or solid-state crystals such as the commonly used
yttrium aluminum garnet ("YAG"). The emitted light is collected and refined
using a series of mirrors and lenses, forming a high intensity, tightly focused
beam of "coherent" light. A laser beam can be made powerful enough to cut steel
or precise enough to perform eye surgery.

    The semiconductor or diode laser uses these same physical principles, but
miniaturizes the entire assembly into a monolithic structure using semiconductor
wafer fabrication processes to build the device. In addition to miniaturizing
the laser, the use of solid-state materials greatly increases the life of the
device and provides power efficiencies over 100 times greater than a typical gas
or lamp based laser. A widely used analogy in the laser industry is that the
development of the semiconductor laser will have as significant an impact on the
use of lasers as the transition of the vacuum tube to the transistor to the
integrated circuit has on the electronics industry.

PRODUCT NARRATIVE

MEDICAL OPERATING SEGMENT

    Coherent's Medical Group (CMG) develops, manufactures and distributes a
broad line of medical laser systems used in ophthalmology, dermatology,
gynecology, plastic surgery, aesthetic surgery, orthopedics, otolaryngology,
neurological surgery, urology, podiatry, oncology and other surgical
specialties. These lasers are designed to improve the quality of patient care
and frequently decrease overall healthcare costs compared to conventional
procedures. Most of these products also make it possible to perform treatments
in a doctor's office, surgi-centers or outpatient centers in hospitals instead
of requiring patient hospitalization.

    AESTHETIC PRODUCTS

    Coherent is a leading supplier of lasers to the rapidly growing aesthetic
laser market. Starting in 1994, with the UltraPulse-TM- for treatment of
wrinkles, Coherent has introduced a complete line of innovative laser products
for aesthetic procedures including laser skin resurfacing, cosmetic eyelid
surgery, treatment of tattoos, treatment of pigmented lesions, treatment of
vascular lesions including leg veins, and laser-assisted hair transplant. In
addition, in April 1999, Coherent finalized the acquisition of Star Medical
(Star) from Palomar Medical Technologies, Inc. for the LightSheer brand of
laser-based hair removal products.

    Prior to concluding the acquisition of Star, Coherent had been the exclusive
distributor for the LightSheer, and introduced it to the market in
February 1998. This compact, solid-state system is the only high-energy, short
pulse laser diode system available for hair removal. The treatment light is
generated by high power diode arrays using patented packaging and cooling
technology. The high efficiency of the diodes is easily transported to multiple
locations. The diode wavelength is well suited for laser hair removal and when
combined with the patented ChillTip-TM- contact skin cooling system, allows
treatment of a wide range of patients. In March of 1999, the LightSheer received
clearance from the FDA to claim permanence in hair removal or reduction, the
only company to have achieved this for a diode laser system.

    The UltraPulse 5000C with Computer Pattern Generator (CPG) is a leading
laser for treatment of wrinkles. Called laser skin resurfacing, this procedure
uses the unique high energy pulsed output of the UltraPulse laser to produce
precise, controlled and repeatable vaporization of a thin outer layer of skin.
The laser is also widely used for aesthetic incisional procedures including
cosmetic eyelid surgery. Since its introduction in 1994, it has become one of
the largest selling lasers to aesthetic surgeons for these procedures.

    In August 1997, the UltraFine erbium laser for skin resurfacing was
introduced. This system complements the UltraPulse 5000C and provides new
treatment capabilities for the aesthetic surgeon. While the UltraPulse remains
the laser of choice for mild to severe wrinkles, the UltraFine erbium laser
extends this treatment to a new group of patients who are seeking more
superficial treatment. In addition, this laser can be used in concert with the
UltraPulse to enhance the overall therapy.

    In 1996, Coherent introduced the multiwavelength VersaPulse C aesthetic
laser. Featuring four lasers in one instrument, this product can be used for a
wide variety of skin procedures such as the removal of tattoos, the treatment of
pigmented lesions, including birthmarks and port wine stains, and the removal of
"telangiectasias," the unsightly veins of the legs and face. Physicians use up
to four separate laser systems to achieve the capabilities offered by a single
VersaPulse aesthetic laser. New laser technology developed at Coherent allows
treatment of lesions containing larger vessels that often do not respond to
conventional lasers.

    The UltraCut incisional scanner for laser-assisted hair transplant was
introduced in October 1997. Used with the UltraPulse line of lasers, the
UltraCut laser prepares sites in the scalp to receive hair grafts.

                                       8

This system offers a number of advantages to hair-transplant surgery including
reduced bleeding, faster procedures and improved cosmetic results.

    OPHTHALMIC PRODUCTS

    Coherent pioneered the use of lasers in the ophthalmology market segment
30 years ago and is continuing this leadership both domestically and globally
today. CMG offers green and multicolor lasers for photocoagulation and treatment
of retinal disease and glaucoma. Coherent's Nd:YAG lasers for photodisruption
are used for treatment of secondary cataracts. Recently Coherent introduced a
new product for Ophthalmic Photodynamic Therapy (PDT) for the treatment of
neovascular Age-Related Macular Degeneration (AMD).

    Coherent's argon photocoagulator was the first such device to achieve
widespread acceptance by the medical community for treatment of diabetic
retinopathy, retinal detachments and glaucoma.

    The Ultima-Registered Trademark- 2000 and Novus-Registered Trademark- 2000
photocoagulator product lines utilize a patented "power-on-demand" laser tube
design where power is on only when required for treatment by the physician. This
innovation substantially extends the laser tube life and eliminates the need for
an external water supply. A broad line of accessories allows these products to
provide Laser Indirect Ophthalmoscopic laser treatment and surgical
endophotocoagulation with Acculite-TM- probes in addition to slit lamp
applications with the LaserLink-TM- Adapter. The portable design of the Ultima
2000 product line allows the system to be transported to the patient for
treatment in convalescent or retirement care facilities, or used in the
operating room, as well as in intensive care nurseries for retinopathy of
prematurity.

    The Novus-Registered Trademark- Verdi-TM- photocoagulator was introduced in
1999 and represents Coherent's first fully solid-state photocoagulator. The
Novus Verdi features rugged portable design, advanced diode pumped green
technology, and patented ClearView-TM- optics all backed by Coherent's solid
commitment to customer service. The Verdi fills out Coherent's photocoagulator
product line resulting in the widest range of choices available to the customer.

    The Novus Omni-TM-, introduced in fiscal 1994, attains a new level of
compactness, reliability, and flexibility in ophthalmic multi-wavelength
applications. With instantaneous switching among red, yellow, and green
treatment options, the retinal surgeon can now benefit from the proven
technology improvements in the Novus and Ultima lasers and multiple wavelength
lasers. For example, as surgeons use lasers in operations and bleeding occurs, a
normal red light will be blended in with the blood of the patient and will not
work correctly. Allowing the doctor to switch the colors of the lasers
eliminates this problem with a more efficient solution.

    Coherent's Nd:YAG laser photodisruptors are used primarily for posterior
capsulotomies. These solid-state, Q-switched lasers provide ophthalmologists
with a method for treating secondary cataracts in a non-invasive manner. Unlike
the argon and multiple wavelength lasers used in photocoagulation, Nd:YAG lasers
produce high power pulses as short as ten billionths of a second. These brief
but powerful pulses produce an "optical breakdown" effect which disrupts (cuts
or tears) the tissue rather than producing a thermal burn. Nd:YAG lasers are
also used for iridotomies, a procedure used in the treatment of closed angle
glaucoma, whereby the laser makes a hole in the iris facilitating the outflow of
fluid trapped in the eye. This outflow relieves pressure, which, if left
untreated, could cause damage to the optic nerve.

    In 1996, Coherent introduced the Selecta 7000-TM- laser, designed to perform
Selective Laser Trabeculotherapy (SLT). Coherent is working with the FDA to
obtain approval for the Selecta 7000. SLT is an exciting new therapy for the
treatment of open angle glaucoma, the leading cause of preventable blindness in
Americans over the age of 40. SLT lowers intraocular pressure by using short
pulses of low energy laser light to illuminate specific cells in the eye's
trabecular meshwork--resulting in increased fluid outflow SLT is being performed
today in many international markets using Coherent's Selecta 7000.

                                       9
<PAGE>
Domestically, Coherent has received exclusive license to commercialize SLT and
market the relevant laser technology.

    In October 1997, Coherent introduced the next generation EPIC-TM-ophthalmic
laser system that enables the ophthalmologist to perform most laser treatments
with one system. In December 1997, Coherent received government approval to sell
this product. This three-in-one laser incorporates a new clip-on Nd:YAG laser, a
frequency doubled laser and an argon laser. The EPIC laser system is a portable
laser, which adapts to the ophthalmologists' existing examination slit lamp.

    In 1999, Coherent introduced the Opal Photoactivator for Visudyne-TM- PDT
therapy for neovascular AMD (the therapy). In November 1999, the FDA Ophthalmic
Drugs Subcommittee recommended approval of the Opal Photoactivator and Visudyne
Therapy for the wet form of age-related macular degeneration. The FDA is
expected to make a final decision regarding the approval of the Visudyne
application on or before February 2, 2000. Regulatory applications are also
pending in the European Union, Canada, Switzerland, Norway, Iceland, Australia
and New Zealand. This new therapy offers a treatment option for the wet form of
AMD, the leading cause of blindness in people over the age of 50 in the western
world. The results of the pivotal Phase III trials showed a statistically
significant benefit at 12 months to those patients treated with Visudyne therapy
compared to those administered a placebo. Results also showed that Visudyne
therapy was well tolerated, with the majority of adverse events occurring in
similar numbers among the treatment and placebo groups.

    SURGICAL PRODUCTS

    Coherent introduced the first solid state holmium laser, the
VersaPulse-Registered Trademark-, in 1988. With its wide variety of fiber optic
delivery devices, which are much smaller than conventional instrumentation, the
VersaPulse quickly established itself as a first choice for minimally invasive
surgery. Since that time, product enhancements and improvements have allowed
Coherent to maintain its leadership position.

    In 1993, the VersaPulse Select-TM- was introduced. This revolutionary
product doubled the holmium laser power available to the arthroscopic surgeon
while reducing the physical size of the system to just half that of previous
models. The tissue effects allowed cutting, ablation and smoothing of
cartilaginous tissue with minimal bleeding. An additional effect of precise
collagen shrinkage has emerged as the procedure of choice for joint instability.

    In urology, the VersaPulse-Registered Trademark- Select-TM- holmium laser is
emerging as a revolutionary option for lithotripsy. With the advent in the
mid-1990's of more flexible, miniturized endoscopic devices, all areas of the
urinary system could be accessed, opening the door for new treatment options.
The holmium laser, coupled with flexible fiber optic delivery devices has proven
to be the most effective lithotrite and the VersaPulse Select is the choice of
leading urologists around the world.

    In 1994, Coherent introduced the VersaPulse Select Dual Wavelength laser for
urology. For the first time, two complementary laser wavelengths, Holmium and
ND:YAG, were incorporated in one system. Via a single delivery device and with
the touch of a foot pedal, the surgeon can quickly switch from the precise
cutting and ablation of Holmium to the deep penetration and coagulation of
Nd:YAG. This combination not only allows maximal versatility in treating the
broadest range of urologic applications but also provides maximal utilization of
the VersaPulse Select within the surgical arena.

    In 1998, Coherent was the first Company to obtain FDA clearance for Holmium
laser prostatectomy. This procedure replaces the conventional treatment,
transurethral resection of the prostrate (TURP), with a procedure that offers
identical surgical effects with less morbidity, shorter hospitalization, and a
quicker return to normal activity. The VersaPulse Select-TM- is quickly becoming
the standard of care for the urologist.

    The medical laser systems manufactured by Coherent's Medical Group are
subject to regulation and control by the U.S. Food and Drug Administration and
other international regulatory agencies. See "Impact of Medical Device
Regulations".

    The laser systems manufactured by the Medical Group typically range in price
from $25,000 to $185,000.

ELECTRO-OPTICS OPERATING SEGMENT

    Coherent's electro-optical products include lasers and laser systems for
micromachining, commercial applications, semiconductor inspection,
telecommunications, scientific, medical research, precision optics and related
accessories. The principal types of lasers produced by Coherent's Electro-Optics
segment are diode-pumped solid-state (DPSS), semiconductor lasers (laser
diodes), argon and krypton ion, excimer, carbon dioxide (CO(2)), liquid dye,
Nd:YAG, and Titanium:Sapphire (Ti:Sapphire). These lasers have a broad range of
power and operate in the visible (V), ultraviolet (UV) and infrared (IR)
portions of the electromagnetic spectrum. Coherent's optics and optical products
include special purpose lenses, mirrors and advanced optical coatings.
Coherent's electro-optical products are sold for commercial and OEM
applications, scientific and medical end users.

    LASER AND COMPONENTS GROUP

    The Coherent Laser Group (CLG) and Coherent Auburn, a division of the
Coherent Laser Group, comprise the Laser and Components Group.

    CLG is headquartered in Santa Clara, California, and is a leading developer
and manufacturer of DPSS, diode, ion, dye, solid-state Nd:YAG, Ti:Sapphire, and
CO(2) lasers for the OEM, micromachining and scientific markets. The lasers sold
by CLG are used in basic and applied research in medicine, chemistry, physics,
biology, biochemistry, engineering and forensic sciences, and in a variety of
commercial applications including materials processing, semiconductor
microlithography, stereolithography, interferometric wafer inspection,
reprographics, optical disk manufacturing, analytical instrumentation, laser
light shows, telecommunications and manufacturing process control.

    In fiscal 1997, CLG continued to provide its customers with lasers for a
growing range of applications, especially in the CO(2) (i.e., material drilling
and marking) and diode-pumped solid state (DPSS) product lines. The Group also
purchased the assets and technology of Micracor, Inc. of Massachusetts to
position CLG for entrance into the telecommunications market. Also, CLG saw
continued strong growth for the Lubeck operation, including shipments of the ZT
laser for the disk texturing market. With these acquisitions and aforementioned
products, CLG has consolidated its patent position in the DPSS area, increased
its portfolio of product offerings to better address the commercial and
micromachining markets, and has opened up a manufacturing and service entity in
Europe for such products. The first shipments of the Verdi-TM-, a CW
diode-pumped solid-state visible laser that provides a compact, high-power,
efficient option for many scientific and commercial laser applications occurred
in fiscal 1997.

    In fiscal 1998, CLG shipped the first units of Avia, a high-power,
high-repetition laser serving the printed circuit board (PCB) via drilling
market. In early 1998, CLG also shipped its first Vittesse laser, offering
customers a self-contained, maintenance free, Ultrafast alternative. Vittesse is
another good example of CLG developing a product for its scientific customers
and then leveraging the technology into commercial applications. CLG continued
to provide its customers with lasers for the growing range of applications,
especially in the CO(2) (i.e., material drilling and marking) and diode-pumped
solid state (DPSS) (i.e., reprographics, holography and rapid prototyping)
product lines. Also, CLG saw continued strong growth for the Lubeck operation,
including shipments of the 315M minilaser for the reprographics market.

                                       11
<PAGE>
    Also in fiscal 1998, CLG entered into a worldwide distribution and minority
ownership agreement with Microlase, located in Glasgow, Scotland. The agreement
provides Microlase with the technical and service support offered by CLG while
CLG benefits from the synergy of combining Microlase's products with its own
diverse product offerings. Microlase has developed a series of technologically
advanced lasers, including extremely narrow linewidth ring lasers and
frequency-doubling technology used in scientific research and precise process
monitoring. Microlase has also developed a series of promising products based on
diode-pumped ultrafast laser sources.

    In 1999, CLG announced a new 980-nm Optically Pumped Semiconductor (OPS)
laser technology that provides the highest power 980-nm laser output from a
single-mode device. High-power 980 nm is critical for pumping Erbium-doped Fiber
Amplifiers (EDFAs)--key components in Dense Wavelength Division Multiplexed
(DWDM) telecommunication systems.

    EDFAs are used to boost optical telecommunications signals that have
degraded after being transported over long distances. Amplifiers for DWDM
networks require higher pump-powers as the number of wavelengths transmitted
through the system is increased. Current 980 nm pump lasers are fundamentally
limited to less than 200 mW (technology limit) necessitating the "ganging" of
several pump lasers with complex schemes to provide adequate pump power for
wide-bandwidth, high-gain DWDM telecommunications systems.

    In 1999, CLG expanded the Verdi and AVIA DPSS lasers as well as the CO(2)
laser product line. Higher power and increased speed lasers were introduced to
the market place with great success. The material processing and electronic
packaging applications for these lasers continued to grow in 1999.

    The lasers and laser systems produced by CLG, with the exception of
semiconductor lasers, typically range in price from $10,000 to $250,000.

    Coherent Auburn (Auburn) manufactures optics, thin films coatings for
high-performance laser optics, laser accessories and electro-optical components
for Coherent as well as other manufacturers.

    Optics and thin film coatings, which consist of mirrors and lenses used for
imaging and directing a laser beam, are used in Coherent's own laser products,
in low-loss coated optics for OEMs and other commercial applications. In
addition to their normal laser business, in fiscal year 1998, the Optics product
line supplied a number of large specialized optics for the Keck Telescope and
Lawrence Livermore Labs NIF program. In England, our Leicester facility received
a UK Design Council Award for the "Millennium Products" recognizing their newly
introduced system for manufacturing graded interference filters.

    Auburn also designs and manufactures laser measurement instruments and
accessories that are used to measure and maximize the performance of laser
systems. The instrument product line continued to see growth in low power diode
laser module sales, and continued demand for their standard line of
instrumentation.

    As a result of the acquisition of Ealing Electro-Optics in fiscal year 1997,
Auburn successfully entered the market for E-O assembly modules, capturing
several major programs from U.S. and European contractors. Also the Catalog
product line, which had taken over the Ealing "Gold" catalog, printed and
distributed in September 1998 the new 480 page Coherent catalog containing 5,000
products, of which 2,000 were new, to the Electro-Optics Industry.

    Products made by Auburn typically range in price from $500 to $50,000 and
are sold through Auburn's field and telemarketing salesforce, the new Coherent
catalog, and through an international network of independent distributors as
well as other Coherent sales groups.

    SEMICONDUCTOR GROUP

    CSG, was spun off from the Laser Group in 1997 to specifically serve
customers in the semiconductor area with high-power laser diodes. Coherent has
been designing and manufacturing a wide variety of lasers

                                       12
<PAGE>
based on diodes since 1986. In 1995, the Company acquired the laser diode
operations of Uniphase Corporation. This acquisition added high power
semiconductor laser diodes with wavelength emission to Coherent's product line.
These diodes are key components for the Company's growing segment of diode-
pumped laser products, thereby reducing its dependence on outside vendors. Laser
diodes are also used in medical, printing, OEM instrumentation, remote sensing,
and machine vision industries.

    In December 1996, Coherent acquired 80% of the outstanding capital stock of
Tutcore OY, Ltd., and an option to acquire the remaining 20% in five years.
Tutcore is located in Tampere, Finland, and is the leading manufacturer of
aluminum-free semiconductor wafers that are incorporated into laser diodes. This
acquisition added capabilities to the line that no other significant supplier
had and allows for a considerable competitive advantage.

    These high-powered diode lasers are expected to have a tremendous impact on
the future of the laser market. These lasers will be used in applications such
as heat-treating, welding, and direct-to-plate printing. These lasers are
created by building rows of miniature lasers on a gallium arsenide wafer, using
semiconductor deposition and etching technology, thereby creating laser bars.
These bars have power outputs equivalent to lasers several cubic feet in size,
therefore making them more portable. Coherent currently has the highest power
bars available in the commercial markets. Larger competitors such as SDL, Inc.,
and Spectra Physics Lasers also make such lasers but produce them containing
aluminum. With the Tutcore acquisition, the semiconductor group is in the
forefront on this laser technology producing aluminum free lasers.

    In February 1997, CSG completed a new, purpose-built diode manufacturing
factory in Santa Clara, California. This 10,000-square foot facility includes
large cleanrooms for wafer processing and packaging, as well as extensive
life-testing and R&D labs.

    Semiconductor laser diode prices range from $200 to $4,000; semiconductor
laser systems range from $3,000 to $20,000. Both laser diodes and laser diode
systems are used in a variety of commercial and OEM applications, including
material processing, reprographics, medical instruments, and laser pumping. CSG
products are incorporated in several other systems manufactured by CLG and CMG.

LAMBDA OPERATING SEGMENT

    Coherent Lambda Physik (CLP), Coherent's 80% owned subsidiary, in Gottingen,
Germany, develops and manufactures excimer, DPSS, and tunable lasers including
dye lasers and optical parametric oscillators (OPOs). These powerful pulsed
lasers cover the spectral range from 157 nm to over 2.5mm. The excimer laser is
very efficient in producing UV light without frequency conversion techniques,
gaining strong market share in commercial and medical applications. The
diode-pumped solid-state developments are driven by the challenge to produce the
highest possible frequency conversion efficiencies and beam quality for UV-power
with outstanding brilliance up to 3 kHz.

    All Lambda Physik products are certified with the CE-mark, a prerequisite
for the European market. This is an important milestone of Lambda Physik's
quality program and opens up excellent opportunities in the medical and
industrial marketplace. Some lasers, which are produced primarily for medical
applications, are even further certified with the CE mark for systems used in
medical products.

    In fiscal year 1999, Lambda Physik pioneered the development of 157 nm
lasers for various applications. The Lambda LPF and the portable OPTex excimer
laser optimized for the wavelength at 157 nm were released. The LPF laser is the
only commercial available laser system at 157 nm that delivers several Watts of
output power. Typical applications are found in spectroscopy, microelectronics,
material processing, material characterization and in chemical vapor deposition.
The OPTex has been especially developed for customers who require a small and
economical, but highly sophisticated, excimer laser.

    The NovaLine F600 and F1000 series are designed for material testing and
feasibility studies of lithography at 157 nm wavelength. These lasers
demonstrate stable operation up to 1 kHz. Lambda Physik

                                       13
<PAGE>
also sells large industrial systems into the TFT annealing market via the
cooperation of an OEM customer in Japan.

    New models, have been added to the product line of 248 nm and 193 nm excimer
lasers for microlithography in order to follow up on the trend of higher power
and tighter laser bandwidth requirements. In September 1999, Lambda Physik
received its first multiple production orders for their high performance excimer
laser systems from a semiconductor equipment manufacturer. The orders are for
Lambda Physik's 248 NovaLine-Registered Trademark- excimer laser systems
operating at 2 kHz pulse rate and will be used in conjunction with a
semiconductor equipment manufacturer's systems. These systems are
high-productivity tools, capable of processing more than 200 mm wafers per hour,
and designed to achieve cost-effective, mix-and-match lithography solutions.
Presently, only Lambda Physik has delivered 2 kHz lasers for 193 nm.

    The LAMBDA StarLine-TM- family of diode-pumped Nd:YAG lasers has been
optimized in close cooperation with industrial key customers. These lasers open
a variety of applications ranging from spectroscopy through LIDAR to hole
drilling and micromachining. Lambda Physik has produced some of the most
respected pulsed laser models for spectroscopy in the world. The present pulsed
dye laser, SCANmate-TM-OG set a new standard in the scientific world in
narrow-linewidth tunable light sources for high resolution spectroscopy in the
range from 189 nm to over 1 mm. SCANmate-TM-OG is the only commercial dye laser
with automatic Autocalibration system.

    Also in fiscal year 1999, ongoing development of the L4308, 200 watt laser
series and line beam optics produced by MicroLas with respect to special needs
of production conditions of polycrystalline flat panel displays has gained a 90%
market share in this fast growing market.

    The lasers and laser systems produced by CLP typically range in price from
$50,000 to $1,000,000.

FINANCIAL INFORMATION ABOUT FOREIGN AND DOMESTIC OPERATIONS AND EXPORT SALES

         FINANCIAL CONDITION

RESULTS OF OPERATIONS

    CONSOLIDATED SUMMARY

    During fiscal 1999, Coherent's net income was $11.8 million ($0.48 per
diluted share), which includes the third quarter $10.7 million ($0.44 per
diluted share) after tax write-off of purchased in-process research and
development resulting from the acquisition of Star Medical Technologies, Inc. of
Pleasanton, California. Proforma net income (exclusive of this write-off) for
fiscal 1999 was $22.6 million ($0.92 per diluted share). Fiscal 1998 net income
was $18.8 million ($0.79 per diluted share), including a $2.7 million ($0.11 per
diluted share) non-recurring tax benefit. Fiscal 1997 proforma net income
(excluding the $9.0 million after tax write-off of purchased in-process
technology) was $35.3 million ($1.50 per diluted share). Proforma income before
income taxes, excluding the aforementioned write-off, increased $8.5 million
(36%) to $32.2 million for fiscal 1999 compared to income before income taxes of
$23.7 million for fiscal 1998, which decreased $23.9 million (43%) compared to
proforma income before income taxes of $56.1 million for fiscal 1997, excluding
the aforementioned write-off. The current year increase was primarily
attributable to increases in international sales volumes and lower SG&A expenses
as a percentage of net sales.

    CONSOLIDATED

    During fiscal 1999, net sales increased $58.5 million (14%) to
$468.9 million from $410.4 million in the prior fiscal year, primarily as a
result of increased sales volumes in the Electro-Optics and Lambda segments
(OEMs and commercial customers). International sales grew at a higher rate than
domestic sales for a total increase of $44.8 million (20%). In particular,
Asia-Pacific sales increased by 26% while European sales increased 16%. The
increase in Asia-Pacific sales reflects signs of an economic recovery.
Accordingly, international sales were 58% of net sales in fiscal 1999 compared
to 55% for fiscal 1998, reflecting Coherent's commitment to grow its
international business.

    The gross margin rate decreased to 47% for the current fiscal year compared
to 48% for fiscal 1998. The deterioration in the overall margin resulted
primarily from higher sales of lower margin products and inventory obsolescence
write-downs of $1.3 million in the Lambda segment.

    ELECTRO-OPTICS

    Electro-Optics net sales increased $39.7 million (20%) in the current fiscal
year to $233.1 million from $193.4 million in the prior fiscal year. Domestic
sales increased $8.3 million (10%) and international sales increased
$31.3 million (29%) in the current fiscal year. Sales increased primarily due to
higher sales volumes in commercial solid state products and in commercial
systems.

    The gross margin rate remained at 47%, consistent with the prior fiscal
year.

    MEDICAL

    Medical net sales increased $7.0 million (5%) to $162.7 million in fiscal
1999 from $155.7 million in fiscal 1998. International sales increased
$3.5 million (5%) and domestic sales increased $3.5 million (4%) in the current
fiscal year. The increase in sales is primarily due to an increase of almost
$28 million in sales of LightSheer hair removal systems partially offset by
lower sales of non-hair removal Aesthetic products and the expiration of our
agreement to distribute ophthalmic refractive systems for a German manufacturer.

    The gross margin rate decreased 0.2% to 48.3% from 48.5% in the prior fiscal
year.

    LAMBDA

    Lambda net sales increased $11.8 million (19%) in the current fiscal year to
$73.1 million from $61.3 million in the prior fiscal year. International sales
increased $10.0 million (24%) and domestic sales increased $1.8 million (9%).
The increase in sales is primarily due to increased shipments of commercial
products, primarily photolithography laser systems.

    The gross margin rate decreased to 45% from 51% in the prior fiscal year.
The decrease from the prior year resulted primarily from increased manufacturing
costs for photolithography systems, lower average selling prices for sales of
scientific products and additional provisions for inventory obsolescence of
$1.3 million.

</TABLE>

    Total operating expenses increased $28.9 million (17%) from the prior fiscal
year. As a percentage of sales, operating expenses increased to 43% from 42% in
the prior year. Exclusive of the third quarter fiscal 1999 write-off of
purchased in-process research and development, operating expenses increased
$12.9 million (7%), but as a percentage of sales decreased to 40% from 42%.

    Current year research and development (R&D) expenses increased $2.3 million
(5%) from the prior fiscal year but decreased to 10% from 11% of sales. The
absolute dollar increase was primarily due to increased headcount and spending
on projects in the Electro-Optics segment.

    Selling, general and administrative (SG&A) expenses increased $9.6 million
(8%) but decreased as a percentage of sales from 30% to 29%. The dollar increase
is primarily due to increases in headcount and related payroll costs in the
Electro-Optics segment to support increased sales volumes. This dollar increase
was also due in part to increased investments in information technology, outside
consulting costs and increased payroll related costs offset partially by the
non-recurrence of fiscal 1998 charges, including: (1) restructuring costs of
$2.9 million related to the medical segment, (2) the relocation of the medical
segment to a new facility, and (3) the Ealing Electro-Optics acquisition costs
associated with the development of a catalog.

    Intangibles amortization increased $1.1 million (23%) primarily due to the
acquisition of Star.

    OTHER INCOME (EXPENSE)

    Other income (expense), net, decreased $1.4 million during the current year
compared to the corresponding prior year period. The decrease was primarily due
to increased interest expense related to financing of the Star acquisition,
partially offset by increased interest income.

    INCOME TAXES

    Coherent's effective tax rate for the current year was 27.0% and its
proforma effective tax rate for the current year (excluding the $10.7 million
write-off of purchased in-process research and development) was 30.0%.
Coherent's proforma effective tax rate for the prior fiscal year (excluding the
$2.7 million non-recurring tax benefit) was 32.1%. The proforma effective tax
rate decreased as a result of the non-recurrence of reserves for exposure items
offset by changes in the distribution taxable income by taxing jurisdiction.

    CONSOLIDATED

    During fiscal 1998, net sales increased $19.4 million (5%) to
$410.4 million from $391.0 million in fiscal 1997, primarily as a result of
increased sales volumes in the Electro-Optics segment (OEM and commercial
customers). International sales grew at a higher rate than domestic sales for a
total increase of $12.2 million (6%) and were 55% of net sales in both fiscal
1998 and 1997.

    The gross margin rate decreased to 48% for fiscal 1998 compared to 53% for
fiscal 1997. The deterioration in the overall margin resulted primarily from
lower sales of higher margin medical products, a shift to higher sales of the
lower margin solid-state technology products in the Electro-Optics segment, and
the impact of the strengthening U.S. dollar against major foreign currencies.

    ELECTRO-OPTICS

    Electro-Optics net sales increased $31.7 million (20%) in fiscal 1998 to
$193.4 million from $161.8 million in fiscal 1997. Domestic sales increased
$11.0 million (14%) and international sales increased $20.6 million (24%) for
fiscal 1998. The increase in sales worldwide resulted primarily from higher
sales volumes in commercial solid-state products and due in part to the Auburn
Division's fiscal 1997 acquisition of Ealing Electro-Optics in Watford, England.
The impact of the strengthening of the U.S. dollar against major foreign
currencies partially offset the increase by adversely impacting international
sales by $5.1 million compared to fiscal 1997.

                                       20
<PAGE>
    The gross margin rate decreased to 47% from 51% in fiscal 1997. The decrease
from fiscal 1997 resulted primarily from a change to a higher mix of lower
margin solid-state, diode, and catalog products, as well as the strengthening of
the U.S. dollar against major foreign currencies.

    MEDICAL

    Medical net sales decreased $14.3 million (8%) to $155.7 million in fiscal
1998 from $170.0 million in fiscal 1997. International sales decreased
$11.7 million (13%) and domestic sales decreased $2.6 million (3%) in fiscal
1998. The decrease in sales resulted primarily from decreased sales volumes,
higher sales returns and allowances and lower average selling prices, as well as
the strengthening of the U.S. dollar against major foreign currencies. Such
strengthening of the U.S. dollar against major foreign currencies contributed to
the decrease in international sales by $3.9 million compared to fiscal 1997.

    The gross profit rate decreased to 49% in fiscal 1998 from 55% in fiscal
1997 primarily due to lower sales and margins on skin resurfacing products,
lower manufacturing throughput, as well as higher inventory related costs,
warranty costs and manufacturing variances and due in part to the strengthening
of the U.S. dollar against major foreign currencies. These factors were
partially offset by the inaugural sales of the new LightSheer hair removal
laser, for which Coherent recognized a commission for its selling efforts.

    LAMBDA

    Lambda net sales increased $2.0 million (3%) in fiscal 1998 to
$61.3 million from $59.3 million in fiscal 1997. Domestic sales decreased
$1.2 million (6%) and international sales increased $3.2 million (8%) for fiscal
1998. The increase in sales worldwide resulted primarily from higher sales
volumes in the lithography business. The impact of the strengthening of the U.S.
dollar against major foreign currencies partially offset the increase by
adversely impacting international sales by $3.4 million compared to fiscal 1997.

    The gross margin rate increased to 51% from 50% in fiscal 1997. The increase
from fiscal 1997 resulted primarily from the strengthening of the U.S. dollar
against major foreign currencies.

</TABLE>

    Total operating expenses increased $10.5 million (6%) from fiscal 1997.
Exclusive of the first quarter fiscal 1997 write-off of purchased in-process
technology, operating expenses increased $19.9 million (13%), and as a
percentage of sales increased to 42% from 39%.

    Fiscal 1998 research and development (R&D) expenses increased $5.1 million
(13%) from fiscal 1997 and increased to 11% from 10% of sales. The absolute
dollar increase was primarily in Coherent's Electro-Optics and Lambda segments
due to due to more headcount and related expenses associated with Coherent's
continued emphasis on product development, including lithography, and its recent
strategic acquisitions.

                                       21
<PAGE>
    Selling, general and administrative (SG&A) expenses increased $13.7 million
(12%) and increased as a percentage of sales from 28% to 30% in fiscal 1998. The
increase, primarily in the Electro-Optics business segment, was driven by recent
business acquisitions, the ramp-up of catalog operations, increased costs
associated with higher headcount and higher costs associated with the
Asia-Pacific region. This increase was also driven by (1) restructuring costs of
$2.9 million related to the medical segment, (2) the relocation of the medical
segment to a new facility, (3) the Ealing Electro-Optics acquisition costs
associated with launching the catalog and (4) higher costs in Asia-Pacific
associated with the Laser Group selling direct in Japan since mid fiscal 1997.

    Intangibles amortization expense increased $1.0 million (27%) due to
amortization of Palomar distribution rights in the medical segment.

    OTHER INCOME (EXPENSE)

    Other income (expense), net, decreased $4.9 million during fiscal 1998
compared to fiscal 1997. Fiscal 1997 other income included a $3.5 million gain
on Coherent's sale of its former headquarters facility. The remaining
fluctuation of $1.4 million was primarily due to higher foreign exchange losses
due to the strengthening of the U.S. dollar against major foreign currencies,
lower royalty income and lower interest income on lower average cash and
investment balances.

    INCOME TAXES

    Coherent's effective tax rate for fiscal 1998 was 20.6% and the proforma
effective tax rate for fiscal 1998 (excluding the $2.7 million non-recurring tax
benefit) was 32.1%. Coherent's proforma effective tax rate for fiscal 1997
(excluding the $9.2 million pre-tax write-off of purchased in-process
technology) was 37%. The proforma effective tax rate decreased as a result of
increases in foreign tax credit utilization and increased research and
development credits offset by changes in the distribution of taxable income by
taxing jurisdiction, as well as the proportionately greater impact of these
items due to the lower income before taxes in fiscal 1998.

BUSINESS ENVIRONMENT

YEAR 2000 COMPLIANCE

    As is true for most companies, the Year 2000 computer issue creates a risk
for Coherent. If systems do not correctly recognize date information when the
year changes to 2000, there could be an adverse impact on Coherent's operations.
The risk for Coherent exists in four areas: (i) information technology used by
Coherent to run its business, (ii) systems used by Coherent's suppliers,
(iii) potential warranty or other claims from Coherent's customers, and
(iv) the potential for reduced spending by customers for Coherent's products as
a result of significant spending on Year 2000 issues and related adverse effects
of such issues on the customer's business. Coherent evaluated its exposure in
all of these areas.

    Coherent completed a comprehensive inventory and evaluation of its internal
systems, equipment and facilities on July 30, 1999. Coherent has completed a
number of projects that replaced or upgraded systems, equipment and facilities
that were already known not to be Year 2000 ready. Coherent substantially
completed these projects on October 8, 1999. Coherent has determined that
upgrades and replacements to its primary systems will allow Coherent to
transition into the new millenium with little or no disruption. Coherent has
established contingency problem management programs to address and resolve Y2K
related issues as the Company crosses through and into the millenium period. For
the Year 2000 issues identified to date, the cost of upgrade or replacement has
been less than $1.5 million through October 31, 1999. If significant new issues
are identified, Coherent's results of operation or financial condition could be
adversely affected.

                                       22
<PAGE>
    Coherent also contacted its critical suppliers to determine that the
suppliers' operations and the products and services they provide are Year 2000
ready. Critical suppliers have provided Coherent Y2K information that indicates
they will continue to be a viable supplier into the Year 2000. Where practical,
Coherent has attempted to mitigate its risks with respect to the failure of
suppliers to be Year 2000 ready. In the event that suppliers are not Year 2000
compliant, Coherent will seek alternative sources of supplies. However, such
failures remain a possibility and could have an adverse impact on Coherent's
results of operations or financial condition.

    Coherent believes the large majority of its current products are Year 2000
compliant; however, since all customer situations cannot be anticipated,
particularly those involving third party products, Coherent may see an increase
in warranty and other claims as a result of the Year 2000 transition. While
litigation regarding Year 2000 compliance issues is expected to escalate,
Coherent does not believe that the impact of customer claims would materially
affect Coherent's results of operations or financial condition.

    Year 2000 readiness is an issue for virtually all businesses, whose systems
and applications may require significant hardware and software upgrades or
modifications. Companies owning and operating such systems may plan to devote a
substantial portion of their information systems' spending to fund such upgrades
and modifications and divert spending away from the purchase of Coherent
products and services. Such changes in customers' spending patterns could have
an adverse impact on Coherent's sales, operating results and financial
condition.

EURO CONVERSION

    As with many multinational companies operating in Europe, beginning in
January 1999, Coherent was affected by the conversion of eleven European
currencies into a common currency, the euro. Based on its assessment, Coherent
does not believe the conversion will have a material impact on the
competitiveness of its products or increase the likelihood of contract
cancellations in Europe, where there already exists substantial price
transparency. Coherent also believes its current accounting systems will
accommodate the euro conversion with minimal intervention and does not expect to
experience material adverse tax consequences as a result of the conversion. The
convergence of currencies into the euro has simplified Coherent's currency risk
management process, including its use of derivatives to manage that risk. The
cost of addressing the euro conversion is not expected to be material and will
be charged to operations as incurred. Coherent will continue to assess the
impact of the introduction of the euro currency over the transition period as
well as the period subsequent to the transition period, as applicable.

MARKETING, DISTRIBUTION AND CUSTOMER SERVICE AND SUPPORT

    Coherent markets its products domestically through a direct sales force.
Coherent's products are sold internationally through direct sales personnel
located in the United Kingdom, Sweden, Finland, Germany, Italy, Austria, France,
Belgium, The Netherlands, Japan (Lambda Physik for commercial products only),
The Peoples Republic of China and Hong Kong, as well as through independent
representatives in other parts of the world. Coherent's foreign sales are made
principally to customers in Europe, Japan and Asia Pacific, but sales are also
made to customers in Canada, Mexico, Latin America, Australia, the Middle East
and Africa. Sales made to independent representatives and distributors are
generally priced in U.S. dollars. Foreign sales made directly by Coherent are
generally priced in local currencies and are therefore subject to currency
exchange fluctuations. Foreign sales are also subject to other normal risks of
foreign operations, such as protective tariffs, export/import controls and
sovereign risk. Coherent's products are broadly distributed and no one customer
accounted for more than 10% of total sales during fiscal 1999.

    Coherent commenced direct sales and service for its Medical and
Electro-Optics industry segments in Japan effective February 1996 and
April 1997, respectively. Japan is the largest international market for both
industry segments. The local presence continues to build closer relationships
with Japanese customers

                                       23
<PAGE>
and enable the Company to provide stronger support and allow development of new
products more rapidly for the Japanese market.

    Coherent maintains a customer support and field service staff in major
markets in the United States, Mexico, Europe, Japan and Asia-Pacific. This
organization works closely with customers, customer groups and independent
representatives in servicing equipment, training customers to use Coherent's
products and exploring additional applications of Coherent's technologies.
Additionally, Coherent gives various warranties on its products and offers
service on a contractual basis after the initial product warranty has expired.

    The Company has also implemented a 24-hour a day service station, where
customers can call a number at any time and receive service on their particular
products. If components of the laser need to be fixed, then the customers can
Federal Express the component back to Coherent as Coherent sends a new part, so
that time is not lost in the production process of the customer.

BACKLOG

    At October 2, 1999 Coherent's backlog of orders scheduled for shipment was
approximately $101,556,000 compared with $87,816,000 at September 26, 1998.
Orders used to compute backlog are generally cancelable without substantial
penalties. Historically, the rate of cancellation experienced by Coherent has
not been significant; however, since orders are cancelable, the backlog of
orders, at any one time, is not necessarily indicative of future revenues.
Coherent anticipates filling the present backlog during fiscal 2000. Backlog at
October 2, 1999 was higher than at September 26, 1998, in all three operating
segments.

FINANCIAL CONDITION

LIQUIDITY AND CAPITAL RESOURCES

    At October 2, 1999, Coherent's primary sources of liquidity are cash and
short-term investments of $68.9 million. Additional sources of liquidity are
Coherent's multi-currency line of credit and bank credit facilities totaling
$58.9 million as of October 2, 1999, of which $46.9 million is unused and
available under these credit facilities. During fiscal 1999, such facilities
have been used in Europe and Japan. Because of Coherent's low debt to equity
ratio (.35), management believes that additional cash could be borrowed if
necessary; however, cash flow from operations, cash and equivalents, short-term
investments and available lines of credit are expected to be sufficient to fund
operations for fiscal 2000. Coherent has certain financial covenants related to
its lines of credit. At October 2, 1999, Coherent is in compliance with these
covenants (see Note 5, "Short-term Borrowings", of Notes to Consolidated
Financial Statements).

    During the first quarter of fiscal 1997, Coherent signed a lease for 216,000
square feet of office, research and development and manufacturing space for its
Medical Group headquarters in Santa Clara, California. The lease expires in
December 2001. Coherent has an option to purchase the property for
$24.0 million, or at the end of the lease arrange for the sale of the property
to a third party with Coherent retaining an obligation to the owner for the
difference between the sale price, if less than $24.0 million, and
$24.0 million, subject to certain provisions of the lease. If Coherent does not
purchase the property or arrange for its sale as discussed above, Coherent would
be obligated for an additional lease payment of approximately $21.5 million.
Coherent occupied the building in July 1998 and commenced lease payments at that
time. The lease requires Coherent to maintain specified financial covenants, all
of which Coherent was in compliance with as of October 2, 1999.

CHANGES IN FINANCIAL CONDITION

    Cash and equivalents at October 2, 1999 increased by $22.3 million (140%)
from September 26, 1998. Operations and changes in exchange rates generated
$37.2 million including an increase in short-term

                                       24
<PAGE>
investments of $13.7 million. Investing activities used $90.3 million;
$21.3 million was used to acquire property and equipment (net of proceeds from
disposition of property and equipment) and $64.0 million was used for business
acquisitions. Financing activities provided $75.4 million; sales of shares under
employee benefit plans generated $3.3 million and increased net borrowings
provided $72.1 million.

    Cash and equivalents at September 26, 1998 decreased by $5.5 million (26%)
from September 27, 1997. Operations and changes in exchange rates generated
$17.7 million including an increase in short-term investments of $6.8 million.
Investing activities used $26.2 million; $22.2 million was used to acquire
property and equipment (net of proceeds from disposition of property and
equipment) and $0.8 million was used for business acquisitions. Financing
activities provided $3.0 million; sales of shares under employee benefit plans
generated $6.8 million and decreased net borrowings used $3.8 million.

ITEM 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

    INTEREST RATE SENSITIVITY

    Coherent maintains a short-term investment portfolio consisting mainly of
income securities with an average maturity of less than one year. These trading
securities are subject to interest rate risk and will fall in value if market
interest rates increase. If market interest rates were to increase immediately
and uniformly by 10 percent from levels at October 2, 1999, the fair value of
the portfolio would decline by an immaterial amount. Coherent has the ability to
generally hold its fixed income investments until maturity and therefore
Coherent would not expect is operating results or cash flows to be affected to
any significant degree by the effect of a sudden change in market interest rates
on its securities portfolio.

    Coherent has fixed rate long-term debt of approximately $77.1 million, and a
hypothetical 10 percent decrease in interest rates would not have a material
impact on the fair market value of this debt. Coherent does not hedge any
interest rate exposures.

    FOREIGN CURRENCY EXCHANGE RISK

    Coherent has foreign subsidiaries, which sell and manufacture its products
in various global markets. As a result, Coherent's earnings and cash flows are
exposed to fluctuations in foreign currency exchange rates. Coherent attempts to
limit these exposures through operational strategies and financial market
instruments. Coherent utilizes hedge instruments, primarily forward contracts
with maturities of twelve months or less, to manage its exposure associated with
firm intercompany and third-party transactions and net asset and liability
positions denominated in non-functional currencies. Coherent does not use
derivative financial instruments for trading purposes.

    Coherent had $24.1 million of short-term forward exchange contracts,
denominated in major foreign currencies, which approximated the fair value of
such contracts and their underlying transactions at October 2, 1999. Gains and
losses related to these instruments at October 2, 1999 were not material.
Looking forward, Coherent does not anticipate any material adverse effect on its
consolidated financial position, results of operations, or cash flows resulting
from the use of these instruments. There can be no assurance that these
strategies will be effective or that transaction losses can be minimized or
forecasted accurately.

    The following table provides information about Coherent's foreign exchange
forward contracts at October 2, 1999. The table presents the value of the
contracts in U.S. dollars at the contract exchange rate as of the contract
maturity date. Due to the short-term nature of these contracts, the fair value
approximates the weighted average contractual foreign currency exchange rate
value of the contracts at October 2, 1999.

                          INDEPENDENT AUDITORS' REPORT

To the Stockholders and Board of Directors of Coherent, Inc.:

    We have audited the accompanying consolidated balance sheets of
Coherent, Inc. and its subsidiaries, as of October 2, 1999 and September 26,
1998, and the related consolidated statements of income, stockholders' equity
and cash flows for each of the three fiscal years in the period ended
October 2, 1999. Our audits also included the consolidated financial statement
schedule listed in Item 14.(a)2. These financial statements and the financial
statement schedule are the responsibility of Coherent's management. Our
responsibility is to express an opinion on the financial statements and the
financial statement schedule 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, such consolidated financial statements present fairly, in
all material respects, the financial position of Coherent, Inc. and its
subsidiaries at October 2, 1999 and September 26, 1998, and the results of their
operations and their cash flows for each of the three years in the period ended
October 2, 1999 in conformity with generally accepted accounting principles.
Also, in our opinion, such financial statement schedule, when considered in
relation to the basic consolidated financial statements taken as a whole,
presents fairly in all material respects the information set forth therein.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF CONSOLIDATION

    The consolidated financial statements include the accounts of
Coherent, Inc. and its majority owned subsidiaries (collectively, the Company or
Coherent). All significant intercompany balances and transactions have been
eliminated. Investments in business entities in which Coherent does not have
control, but has the ability to exercise significant influence over operating
and financial policies (generally 20-50% ownership), are accounted for by the
equity method.

FISCAL YEAR

    Coherent's fiscal year for 1999 included 53 weeks, fiscal 1998 and 1997 each
included 52 weeks.

USE OF ESTIMATES

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Such estimates include, but are not limited to, allowances for
uncollectible accounts receivable and sales returns reserves, inventory
reserves, warranty costs, depreciation and amortization, taxes and
contingencies. Actual results could differ from those estimates.

ADOPTION OF NEW ACCOUNTING STANDARDS

    Coherent adopted Financial Accounting Standards Board Statement (SFAS)
No. 131, "Disclosure about Segments of an Enterprise and Related Information" in
fiscal 1999. The statement requires certain financial and descriptive
information about operating segments, profit or loss, certain specific revenue
and expense items and segment assets. (See Note 13). The adoption of SFAS
No. 131 has no impact on the Company's net income, balance sheet or
stockholders' equity.

RECENTLY ISSUED ACCOUNTING STANDARDS

    In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities". This statement
requires companies to record derivatives on the balance sheet as assets or
liabilities, measured at fair value. Gains or losses resulting from changes in
the values of those derivatives would be accounted for depending on the use of
the derivative and whether it qualifies for hedge accounting. In May 1999,
SFAS 133 was amended to defer its effective date. SFAS 133 will be effective for
Coherent's first quarterly filing of 2001. Management believes that this
statement will not have a significant impact on the Company's financial position
or results of operations.

FOREIGN CURRENCY TRANSLATION

    The functional currency of Coherent's foreign subsidiaries is their
respective local currencies. Accordingly, gains and losses from the translation
of the financial statements of the foreign subsidiaries are reported as a
separate component of accumulated other comprehensive income. Foreign currency
transaction gains and losses are included in net earnings.

1. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS

    Coherent's policy is to invest in various short-term debt instruments
including certificates of deposit, bankers acceptances and repurchase agreements
of major banks and institutions, obligations of the U.S. Treasury and U.S.
Government agencies, tax-exempt municipal securities and commercial paper with
credit ratings of A1 and P1. All highly liquid debt instruments purchased with a
remaining maturity of three months or less are classified as cash equivalents.

INVENTORIES

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

GOODWILL

    Goodwill relates to acquired subsidiaries and is being amortized on a
straight-line basis over estimated useful lives of three to forty years.
Coherent evaluates its long-lived assets, including goodwill, for impairment
whenever events or changes in circumstances indicate that the carrying value of
an asset may not be recoverable.

INTANGIBLE ASSETS

    Intangible assets, recorded as other assets, include distribution rights,
acquired existing technology, licenses and patents and are amortized on a
straight-line basis over estimated useful lives of two to seventeen years.
Coherent evaluates its long-lived assets, including intangible assets, for
impairment whenever events or changes in circumstances indicate that the
carrying value of an asset may not be recoverable.

1. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

WARRANTY

    Coherent warrants certain of its products and provides for estimated product
warranty costs at the time of sale.

REVENUE RECOGNITION

    Coherent generally recognizes revenue from product sales upon shipment or
title transfer, if later, and from service upon performance or over the terms of
the service contract as appropriate.

CONCENTRATION OF CREDIT RISK

    Financial instruments which may potentially subject Coherent to
concentrations of credit risk consist principally of cash equivalents,
short-term investments and accounts receivable. Coherent invests only in U.S.
Treasury obligations or with high credit quality financial institutions and, by
policy, limits the amount of credit exposure to any one institution. At
October 2, 1999, the majority of its short-term investments are in repurchase
agreements, corporate obligations and federal agency obligations. The majority
of Coherent's accounts receivable are derived from sales to customers for
medical and surgical applications, scientific research applications, and
commercial applications. Coherent performs ongoing credit evaluations of its
customers' financial condition and limits the amount of credit extended when
deemed necessary but generally requires no collateral. Coherent maintains
reserves for potential credit losses.

INCOME TAXES

    Coherent accounts for income taxes using the asset and liability method.
Deferred tax assets and liabilities are recognized for the future tax
consequences of temporary differences between the financial statement carrying
amounts and the tax bases of assets and liabilities. A valuation allowance is
established to reduce the deferred tax asset if it is "more likely than not"
that the related tax benefits will not be realized in the future.

    Federal income taxes have not been provided on a portion of the unremitted
earnings of foreign subsidiaries either because such earnings are intended to be
permanently reinvested or because foreign tax credits are available to offset
any planned distributions of such earnings. The total amount of unremitted
earnings of foreign subsidiaries was approximately $46,142,000 at October 2,
1999. Withholding taxes of approximately $2,270,000 would be payable upon
repatriation of such earnings which would result in additional foreign tax
credits.

DERIVATIVES

    Coherent enters into forward exchange contracts to minimize the short-term
impact of foreign currency fluctuations on assets and liabilities and firm
commitments denominated in currencies other than the functional currency of the
reporting entity. All foreign exchange forward contracts are designated as and
effective as a hedge and are highly inversely correlated to the hedged item as
required by generally accepted accounting principles. Gains and losses on the
contracts that hedge foreign currency assets and liabilities are included in
other income and offset foreign exchange gains or losses from the revaluation of
intercompany balances or other current assets and liabilities denominated in
currencies other than the functional currency of the reporting entity. The cash
flow impact of Coherent's derivative hedges offsets the cash flow impact of the
foreign exchange movements on the underlying exposed asset and liability.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

1. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Gains and losses on contracts that hedge firm commitments of foreign currency
purchases or sales are deferred and recognized at the time the hedged
transaction is recorded as an offset to the amount of the related purchase or
sale. Fair values of foreign exchange contracts are determined by obtaining
quoted market prices of comparable contracts, adjusted through interpolation
where necessary for maturity differences.

EARNINGS PER SHARE

    Earnings per share (EPS) are computed as basic EPS using the weighted
average number of common shares outstanding and diluted EPS using the weighted
average number of common and dilutive common shares outstanding, in accordance
with SFAS 128 (See Note 10).

COMPREHENSIVE INCOME

    On September 27, 1998, Coherent adopted SFAS No. 130, "Reporting
Comprehensive Income," which establishes standards for reporting and displaying
comprehensive income and its components. Comprehensive income is defined as the
change in equity of a business enterprise during a period from transactions and
other events and circumstances from non-owner sources.

STOCK-BASED COMPENSATION

    As permitted under SFAS 123, "Accounting for Stock-Based Compensation"
Coherent accounts for stock-based awards to employees using the intrinsic value
method in accordance with Accounting Principles Board Opinion No. 25 (APB 25),
"Accounting for Stock Issued to Employees". (See Note 9).

RECLASSIFICATIONS

    Certain prior year amounts have been reclassified to conform with the
current year presentation. Such reclassifications had no impact on net income or
stockholders' equity for any year presented.

2. ACQUISITIONS

    During the three fiscal years ended October 2, 1999, Coherent made the
acquisitions described in the following paragraphs, each of which has been
accounted for as a purchase. The consolidated financial statements include the
operating results of each business from the date of acquisition. Proforma
results of operations have not been presented, except for the acquisition of
Star Medical Technologies, Inc., because the effects of these acquisitions were
not material on either an individual or an aggregate basis. The amounts
allocated to purchased in-process research and development were determined
through established valuation techniques in the high technology industry and
were expensed upon acquisition, because technological feasibility had not been
established and no future alternative uses existed. Research and development
costs to complete development of the research and development from these
acquired companies to technological feasibility are not expected to have a
material impact on Coherent's future results of operations or cash flows.
Amounts allocated to goodwill and other intangibles arising from such
acquisitions are amortized on a straight-line basis over periods ranging from
three to fifteen years.

    In April 1999, Coherent acquired all of the outstanding shares of Star
Medical Technologies, Inc. (Star) for approximately $67.0 million (consisting of
$65.0 million in cash, $1.7 million of unamortized distribution rights and
$0.3 million of acquisition costs) from Palomar Medical Technologies, Inc. and

certain Star employees. Star, based in Pleasanton, California, manufactures
LightSheer-TM- laser diode systems, which have received FDA approval for hair
removal and the treatment of leg veins. The acquisition was treated as a
purchase and, accordingly, the acquired assets and liabilities were recorded at
their fair market values at the date of acquisition.

    The aggregate purchase price of $67.0 million (including acquisition costs)
has been allocated to the assets and in-process research and development
acquired. The total purchase price was allocated among the assets acquired
(including acquired in-process research and development) as follows (in
thousands):

    The goodwill is being amortized over its estimated useful life of 15 years.
The existing technology and workforce assets are being amortized over their
estimated useful lives of 7 and 3 years, respectively.

    The purchase price allocation and intangible valuation was based on
management's estimates of the after-tax net cash flows and gave explicit
consideration to the Securities and Exchange Commission's views on purchased
in-process research and development as set forth in its September 9, 1998 letter
to the American Institute of Certified Public Accountants. Specifically, the
valuation gave consideration to the following: (i) the employment of a fair
market value premise excluding any Coherent-specific considerations which could
result in estimates of investment value for the subject assets;
(ii) comprehensive due diligence concerning all potential intangible assets
including trademarks\trade names, patents, copyrights, noncompete agreements,
assembled workforce, customer relationships and sales channel; (iii) the value
of existing technology was specifically addressed, with a view toward ensuring
the relative allocations to existing technology and in-process research and
development were consistent with the relative contributions of each to the final
product; and (iv) the allocation to in-process research and development was
based on a calculation that considered only the efforts completed as of the
transaction date, and only the cash flow associated with said completed efforts
for one generation of the products currently in process.

    As indicated above, Coherent recorded a one-time charge of $16,000,000
($10,734,000 net of tax) in 1999 for purchased in-process research and
development related to five development projects. The charge related to the
portion of these products, excluding existing technology, that had not reached
technological feasibility, had no alternative future use and for which
successful development was uncertain. Management's conclusion that the
in-process development effort had no alternative future use was reached in
consultation with the engineering personnel from both Coherent and Star.

    The first of these projects is a new product in the LightSheer family that
results in a 50% increase in power and twice the coverage by incorporating a new
heat exchanger, thermoelectric cooling system,

sapphire tip and software. At the time of acquisition, the development was 86%
complete and the estimated cost to complete was $0.2 million. Coherent began
shipping the product in May 1999. The second of these projects is a next
generation LightSheer product that incorporates a new microprocessor and
touch-screen as well as redesigns the packaging to improve serviceability. At
the time of acquisition, the development was 78% complete and the estimated cost
to complete was $0.5 million. Coherent began shipping the product in July 1999.
The third of these projects is a new product in the LightSheer family that will
result in increased coverage and will require a new clinical trial. At the time
of acquisition, the development was 72% complete and the estimated cost to
complete was $0.6 million. Management expects that the product will become
available for sale in fiscal 2000. The fourth project is a new application of
the semiconductor diode array technology, originally developed for hair removal,
in a laser-based diagnostic system. At the time of acquisition, the development
was 58% complete and the estimated cost to complete was $1.0 million. Management
expects that the product will become available for sale in fiscal 2001. The
fifth development project is an ensemble of diode array products. At the time of
acquisition, the development was 54% complete and the estimated cost to complete
was $1.4 million. Management expects that the product will become available for
sale in fiscal 2001, however, no assurances can be given as to the availability,
if any.

    Coherent will begin to benefit from the acquired research and development of
these products once they begin shipping. Failure to reach successful completion
of these projects could result in impairment of the associated capitalized
intangible assets and could require Coherent to accelerate the time period over
which the intangibles are being amortized, which could have a material adverse
effect on Coherent's business, financial condition, or results of operation.

    Significant assumptions used to determine the value of in-process research
and development included several factors, including the following: (i) forecast
of net cash flows that were expected to result from the development effort using
projections prepared by Coherent's and Star's management; (ii) percentage
complete for the projects estimated by considering a number of factors,
including the costs invested to date relative to total cost of the development
effort and the amount of progress completed as of the acquisition date, on a
technological basis, relative to the overall technological achievements required
to achieve the functionality of the eventual product. The technological issues
were addressed by engineering representatives from both Coherent and Star, and
when estimating the value of the technology, the projected financial results of
the acquired assets were estimated on a stand-alone basis without any
consideration to potential synergic benefits or "investment value" related to
the acquisition. Accordingly, separate projected cash flows were prepared for
both the existing as well as the in-process projects. These projected results
were based on the number of units sold times average selling price less the
associated costs. After preparing the estimated cash flows from the products
being developed, a portion of these cash flows were attributed to the existing
technology, which was embodied in the in-process product lines and enabled a
quicker and more cost-effective development of these products. When estimating
the value of the existing and in-process technologies, discount rates of 15% and
30% were used, respectively. The discount rates considered both the status and
risks associated with the respective cash flows at the acquisition date.

    In May 1999, Coherent issued $70 million of Senior Notes in a private bond
placement to finance the acquisition of Star. $44 million of the notes are due
in annual installments from May 2000 through May 2006, at a fixed interest rate
of 6.7%, and $26 million of the notes are due in annual installments from
May 2004 through May 2006, at a fixed interest rate of 6.91%.

    In December 1997, Coherent entered into a joint venture agreement with Fiber
Optic Network Solutions Corporation (FONS) and Fiber Optic Transmission Systems
Corporation to engage in the business of the design, development, production and
marketing of fiber optic transmission and distribution systems in the field of
CATV, telecommunications and high-speed data transmission. A limited liability
company was formed, CFX Communication Systems, LLC, to which Coherent paid
$0.5 million to FONS' owners in exchange for 60% ownership of CFX. Coherent
recorded $0.4 million of goodwill associated with the purchase. The CFX joint
venture was unable to achieve its business objectives and ceased operations in
May 1999. The related goodwill has been fully amortized.

    In May 1997, Coherent acquired the assets and operations of Ealing
Electro-Optics, located in Watford, England and its U.S. subsidiary located in
Holliston, Massachusetts for approximately $9.5 million in cash. Ealing is a
recognized leader in the design and manufacture of precision optical assemblies
as well as complete lens and thermal imaging test systems. In addition, Ealing
is a distributor of electro-optic components and its "Gold" catalog sells over
5,000 components to the photonics industry. The acquisition was accounted for as
a purchase and, accordingly, Coherent has recorded the approximately
$4.0 million excess of the purchase price over the fair value of net assets
acquired as goodwill, which is being amortized over 10 years.

    In December 1996, Coherent acquired 80% of the outstanding shares of Tutcore
OY Ltd., located in Tampere, Finland for approximately $10.0 million (consisting
of $4.0 million of cash, $5.4 million of deferred payment obligations and
$0.6 million of acquisition costs). Tutcore specializes in the growth and
processing of aluminum-free epitaxial wafers used in semiconductor lasers. Also
in December 1996, Coherent purchased the net assets of Micracor, Inc. of Acton,
Massachusetts for approximately $0.9 million (consisting of $0.8 million of cash
and $0.1 million of acquisition costs). Micracor manufactures materials used in
semiconductor-based solid state microchip lasers for the telecommunications
market. These acquisitions were accounted for as purchases and, accordingly, the
acquired assets and liabilities were recorded at their estimated fair market
values at the dates of the acquisitions. The aggregate purchase price of
$10.9 million (including acquisition costs) has been allocated to the assets and
liabilities acquired. Approximately $9.3 million of the total purchase price for
these entities represented the value of in-process technology that had not yet
reached technological feasibility and had no alternative future use, and was
charged to operations during the first quarter of fiscal 1997. Coherent's
consolidated results of operations include the operating results of the acquired
companies from their acquisition dates.

4. FINANCIAL INSTRUMENTS

FAIR VALUE OF FINANCIAL INSTRUMENTS

    The following methods and assumptions were used to estimate the fair value
of each class of financial instruments for which it is practicable to estimate
that value.

    Cash equivalents and short-term investments are stated at fair market value
based on quoted market prices.

    The recorded carrying amount of Coherent's long-term obligations
approximates fair market value.

    The carrying amount and fair value of foreign exchange contracts was
$24.1 million at October 2, 1999. The carrying amount and fair value of foreign
exchange contracts was $29.5 million and $30.0 million at September 26, 1998,
respectively. The fair value of foreign exchange contracts is estimated by
obtaining quoted market prices of comparable contracts, adjusted through
interpolation where necessary for maturity differences.

FOREIGN EXCHANGE CONTRACTS

    In the normal course of business, Coherent has exposures to foreign currency
fluctuations arising from foreign currency sales and purchases and intercompany
transactions, among other things. Coherent uses foreign exchange forward
contracts to limit its exposure to foreign exchange losses arising from
nonfunctional currency payables and receivables and firm commitments. Coherent
evaluates its net exposure therefrom and enters into forward contracts to hedge
the net exposure over a specified amount. These contracts are executed with
credit-worthy financial institutions and are denominated in currencies of major
industrial nations. Gains and losses on these contracts serve as hedges in that
they offset fluctuations that would otherwise impact Coherent's financial
results. Costs associated with entering into such contracts are generally
amortized over the life of the instruments and are not material to Coherent's
financial results.

    At October 2, 1999 and September 26, 1998, Coherent had foreign currency
forward contracts outstanding to hedge foreign currency accounts receivable and
accounts payable and sales backlog usually shippable within 90 days. These
contracts have maturities, which typically range from 90 to 360 days and

8. STOCKHOLDERS' EQUITY

    Each outstanding share of Coherent's common stock carries a stock purchase
right (right) issued pursuant to a dividend distribution declared by Coherent's
Board of Directors and distributed to stockholders of record on November 17,
1989. When exercisable, each right entitles the stockholder to buy one share of
Coherent's common stock at an exercise price of $80. The rights will become
exercisable following the tenth day after a person or group announces
acquisition of 20% or more of Coherent's common stock or announces commencement
of a tender offer, the consummation of which would result in ownership by the
person or group of 30% or more of the common stock. Coherent will be entitled to
redeem the rights at $.01 per right at any time on or before the 10th day
following the acquisition by a person or group of 20% or more of Coherent's
common stock.

    If, prior to redemption of the rights, Coherent is acquired in a merger or
other business combination in which Coherent is the surviving corporation, or a
person or group acquires 30% or more of Coherent's common stock, each right
owned by a holder of less than 20% of the common stock will entitle its owner to
purchase, at the right's then current exercise price, a number of shares of
common stock of Coherent having a fair market value equal to twice the right's
exercise price. If Coherent sells more than 50% of its assets or earning power
or is acquired in a merger or other business combination in which it is not the
surviving corporation, the acquiring person must assume the obligations under
the rights and the rights will become exercisable to acquire common stock of the
acquiring person at the discounted price.

fiscal 1999, 25,097 shares (fair market value of $402,003) and $3,080,306 were
accrued for the benefit of employees. For fiscal 1998, 20,674 shares (fair
market value of $346,889) and $2,467,724 were accrued for the benefit of
employees. For fiscal 1997, 30,616 shares (fair market value of $686,029) and
$4,247,005 were accrued for the benefit of employees. At October 2, 1999,
Coherent had 25,397 shares of its common stock reserved for future issuance
under the Plan.

COHERENT EMPLOYEE RETIREMENT AND INVESTMENT PLAN

    Under the Coherent Employee Retirement and Investment Plan, Coherent matches
employee contributions to the Plan up to a maximum of 6% of the employee's
individual earnings. Employees become eligible for participation and for Company
matching contributions after completing one year of service. Coherent's
contributions (net of forfeitures) for fiscal 1999, 1998, and 1997 were
$3,757,000, $3,322,000 and $3,057,000, respectively.

SUPPLEMENTAL RETIREMENT PLAN

    Coherent has a Supplemental Retirement Plan for senior management personnel
which permits the participants to contribute up to 24% of their before tax
earnings to a trust. Coherent will match these contributions up to an amount
equal to 6% of such participants' earnings less any amounts contributed by
Coherent to such participant under the Coherent Employee Retirement and
Investment Plan. Coherent's contributions (net of forfeitures) for fiscal 1999,
1998, and 1997 were $18,117, $13,602 and $17,834, respectively.

EMPLOYEE STOCK PURCHASE PLAN

    Coherent has an Employee Stock Purchase Plan whereby eligible employees may
authorize payroll deductions of up to 10% of their regular base salary to
purchase shares at the lower of 85% of the fair market value of the common stock
on the date of commencement of the offering or on the last day of the
twelve-month offering period. In fiscal 1999, 180,295 shares were purchased by
and distributed to employees at an average price of $8.55 per share. In fiscal
1998, 208,270 shares were purchased by and distributed to employees at an
average price of $16.11 per share. In fiscal 1997, 155,206 shares were purchased
by and distributed to employees at an average price of $15.69 per share.

    At October 2, 1999, $3,686,000 had been contributed by employees that will
be used to purchase a maximum of 559,988 shares in fiscal 2000 at a price
determined under the terms of the Plan. At October 2, 1999, Coherent had
2,223,000 shares of its common stock reserved for future issuance under the
plan.

STOCK OPTION PLANS

    Coherent has two Stock Option Plans and a non-employee Directors' Stock
Option Plan. Under these plans, Coherent may grant options to purchase up to
9,000,000 and 400,000 shares of common stock, respectively. Employee options are
generally exercisable three years from the grant date, at the fair market

with the annual shareholders meeting, however, initial grants to employees vest
25% annually. Director options are automatically granted to non-employee
directors of Coherent. Such directors initially receive a stock option for
20,000 shares exercisable over a four-year period. Additionally, the
non-employee directors receive an annual grant of 5,000 shares exercisable four
years from the date of grant. Grants under all plans expire six years from the
original grant date.

    Option activity for all plans is summarized as follows:

    SFAS No. 123, "Accounting for Stock-Based Compensation," requires the
disclosure of proforma net income (loss) and earnings (loss) per share had
Coherent adopted the fair value method as of the beginning of fiscal 1996. Under
SFAS 123, the fair value of stock-based awards to employees is calculated
through the use of option pricing models, even though such models were developed
to estimate the fair value of freely tradable, fully transferable options
without vesting restrictions, which significantly differ from Coherent's stock
option awards. These models also require subjective assumptions, including
future stock price volatility and expected time to exercise, which greatly
affect the calculated values.

    Coherent's calculations were made using the Black-Scholes option pricing
model with the following weighted average assumptions:

forfeitures are recognized as they occur. If the computed fair values of the

    The impact of outstanding non-vested stock options granted prior to fiscal
1996 has been excluded from the proforma calculation; accordingly, the fiscal
1999, 1998 and 1997 proforma amounts are not indicative of future period
proforma amounts, when the calculation will apply to all applicable stock
options.

NOTES RECEIVABLE FROM STOCK SALES

    Notes receivable from stock sales result from the exercise of stock options
for notes. The notes are full recourse promissory notes bearing interest at 4.7
to 7.1% and are collateralized by the stock issued upon exercise of the stock
options. Interest is payable annually and principal is due through 2004.

10. EARNINGS PER SHARE

    Basic earnings per share is computed based on the weighted average number of
shares outstanding during the period. Diluted earnings per share is computed
based on the weighted average number of shares outstanding during the period
increased by the effect of dilutive stock options and stock purchase contracts,
using the treasury stock method, and shares issuable under the Productivity
Incentive Plan.

diluted earnings per common and common equivalent share:

COMMITMENTS

    Coherent leases several of its facilities under operating leases. In
addition, Coherent leases the land for its Auburn manufacturing facilities under
long-term fixed leases.

    During the first quarter of fiscal 1997, Coherent signed a lease for 216,000
square feet of office, research and development and manufacturing space for its
Medical Group headquarters in Santa Clara, California. The lease expires in
December 2001. Coherent has an option to purchase the property for
$24.0 million, or at the end of the lease arrange for the sale of the property
to a third party with Coherent retaining an obligation to the owner for the
difference between the sale price, if less than $24.0 million, and
$24.0 million, subject to certain provisions of the lease. If Coherent does not
purchase the property or arrange for its sale as discussed above, Coherent would
be obligated for an additional lease payment of approximately $21.5 million
(included in future minimum lease payments below). Coherent occupied the
building in July 1998 and commenced lease payments at that time. The lease
requires Coherent to maintain specified financial covenants, all of which
Coherent was in compliance with as of October 2, 1999.

    Future minimum payments under Coherent's leases are as follows:

    Rent expense was $8,986,000 in fiscal 1999, $7,593,000 in fiscal 1998, and
$7,462,000 in fiscal 1997.

    In September 1988, Coherent entered into several agreements with Patlex
Corporation (Patlex) whereby Coherent was granted licenses to several laser
related patents developed by Dr. Gordon Gould and assigned to Patlex. Under the
terms of the agreements, Coherent pays royalties to Patlex of 5% or 3.5% and 2%
of certain defined domestic sales and international sales, respectively, subject
to certain exceptions and limitations. Royalty expense under these agreements
was $699,000 in fiscal 1999, $893,000 in fiscal 1998, and $1,131,000 in fiscal
1997. The patents expire on various dates through May 2005.

CONTINGENCIES

    Certain claims and lawsuits have been filed or are pending against Coherent.
In the opinion of management, all such matters have been adequately provided
for, are without merit, or are of such kind that if disposed of unfavorably,
would not have a material adverse effect on Coherent's consolidated financial
position or results of operations.

    Coherent, along with several other companies, has been named as a party to a
remedial action order issued by the California Department of Toxic Substance
Control relating to soil and groundwater contamination at and in the vicinity of
the Stanford Industrial Park in Palo Alto, California, where Coherent's former
headquarters facility is located. The responding parties to the Regional Order
(including Coherent) have completed Remedial Investigation and Feasibility
Reports, which were approved by the State of California. The responding parties
have installed four remedial systems and have reached agreement with responding
parties on final cost sharing.

    Coherent was also named, along with other parties, to a remedial action
order for the Porter Drive facility site itself in Stanford Industrial Park. The
State of California has approved the Remedial Investigation Report, Feasibility
Study Report, Remedial Action Plan Report and Final Remedial Action Report,
prepared by Coherent for this site. Coherent has been operating remedial systems
at the site to remove subsurface chemicals since April 1992. During fiscal 1997,
Coherent settled with the prior tenant and neighboring companies, on allocation
of the cost of investigating and remediating the site at 3210 Porter Drive and
the bordering site at 3300 Hillview Avenue.

    Management believes that Coherent's probable, nondiscounted net liability at
October 2, 1999 for remaining costs associated with the above environmental
matters is $1.0 million, which has been previously accrued. This amount consists
of total estimated probable costs of $1.3 million ($0.1 million included in
other current liabilities and $1.2 million included in other long-term
liabilities) reduced by minimum probable recoveries of $0.3 million included in
other assets from other parties named to the order.

13. OPERATING SEGMENTS

    In fiscal 1999, Coherent adopted SFAS No. 131, "Disclosures about Segments
of an Enterprise and Related Information." The statement establishes standards
for reporting information about operating segments and related disclosures about
products, geographic information and major customers.

    Coherent is organized around four separately managed business units: the
Laser Group, the Semiconductor Group, the Medical Group and the Lambda Group.
Consistent with the rules of SFAS No. 131, we have aggregated these four
business units into three reportable segments. The Semiconductor Group was

combined with the Laser Group in the Electro-Optics segment as they have similar
economic characteristics and are similar in the following: nature of
products\services, nature of production process, type/class of customer,
distribution methods and nature of regulatory environment. The Electro-Optics
segment produces lasers and laser systems for scientific, medical research,
micromachining, commercial applications, semiconductor inspection,
telecommunications, precision optics and related accessories, including optics
and optical products such as special purpose lenses, mirrors and advanced
optical coatings. The Medical segment develops, manufactures and distributes a
broad line of medical laser systems used in ophthalmology, dermatology,
gynecology, plastic surgery, aesthetic surgery, orthopedics, otolaryngology,
neurological surgery, urology, podiatry, oncology, and other surgical
specialties. The Lambda segment develops and manufactures excimer, DPSS, and
tunable lasers including dye lasers and optical parametric oscillators.

    Coherent's Chief Executive Officer and Chief Financial Officer have been
identified as the chief operating decision makers (CODMs) for SFAS 131 purposes
as they assess the performance of the business units and decide how to allocate
resources to the business units. Pretax income is the measure of profit and loss
that our CODMs use to assess performance and make decisions. Pretax income
represents the sales less the cost of sales and direct expenses incurred within
the operating segments. In addition, Coherent's corporate expenses, except for
depreciation of corporate assets and general legal expenses, are allocated to
the operating segments and are included in the results below. Corporate expenses
not allocated to the groups (depreciation of corporate assets and general legal
expenses) are included in Corporate and Other in the reconciliation of operating
results. Further, interest expense, interest income and the provision for income
taxes are included in Corporate and Other in the reconciliation of operating
results.

    Intersegment sales are accounted for primarily at domestic selling prices.
As the CODMs monitor headcount, depreciation and amortization expense and
capital expenditures by operating segment, these amounts are presented below.
The CODMs do not review total assets by segment, but they do review net trade
receivables, net inventories and net property and equipment by operating
segment. The accounting policies for reported segments are the same as for
Coherent as a whole (see Note 1).

TO EACH OF THE PURCHASERS LISTED IN
     THE ATTACHED SCHEDULE A:

Ladies and Gentlemen:

              Coherent, Inc., a Delaware corporation (the "COMPANY"), agrees
with you as follows:

1.     AUTHORIZATION OF NOTES.

       The Company will authorize the issue and sale of $70,000,000 aggregate
principal amount of its Senior Notes as follows:  $44,000,000 6.70% Series A
Senior Notes due May 18, 2006 and $26,000,000 6.91% Series B Senior Notes due
May 18, 2006 (respectively, the "SERIES A NOTES" and the "SERIES B NOTES", and
collectively the "NOTES", such terms to include any such notes issued in
substitution therefor pursuant to Section 13 of this Agreement or the Other
Agreements (as hereinafter defined)).  The Series A Notes shall be substantially
in the form set out in Exhibit 1-A and the Series B Notes shall be substantially
in the form set out in Exhibit 1-B, in each case with such changes therefrom, if
any, as may be approved by you and the Company.  Certain capitalized terms used
in this Agreement are defined in Schedule B; references to a "Schedule" or an
"Exhibit" are, unless otherwise specified, to a Schedule or an Exhibit attached
to this Agreement.


2.     SALE AND PURCHASE OF NOTES.

       Subject to the terms and conditions of this Agreement, the Company will
issue and sell to you and you will purchase from the Company, at the Closing
provided for in Section 3, Notes in the principal amount specified opposite your
name in Schedule A at the purchase price of 100% of the principal amount
thereof.  Contemporaneously with entering into this Agreement, the Company is
entering into separate Note Purchase Agreements (the "OTHER AGREEMENTS")
identical with this Agreement with each of the other purchasers named in
Schedule A (the "OTHER PURCHASERS"), providing for the sale at such Closing to
each of the Other Purchasers of Notes in the principal amount specified opposite
its name in Schedule A.  Your obligation hereunder and the obligations of the
Other Purchasers under the Other Agreements are several and not joint
obligations and you shall have no obligation under any Other Agreement and no
liability to any Person for the performance or non-performance by any Other
Purchaser thereunder.


3.     CLOSING.

       The sale and purchase of the Notes to be purchased by you and the Other
Purchasers shall occur at the offices of O'Melveny & Myers LLP, 400 South Hope
Street, Los Angeles, California 90071 at 8:00 a.m., Los Angeles time, at a

<PAGE>

or prior to May 31, 1999, as may be agreed upon by the Company and you and
the Other Purchasers.  At the Closing the Company will deliver to you the
Notes to be purchased by you in the form of a single Note (or such greater
number of Notes in denominations of at least $100,000 as you may request)
dated the date of the Closing and registered in your name (or in the name of
your nominee), against delivery by you to the Company or its order of
immediately available funds in the amount of the purchase price therefor by
wire transfer of immediately available funds for the account of the Company
to:  Bank of America, San Francisco, California, ABA # 121000358, account
name: Incoming Money Transfer, account # 12331-83980, ref:  attn.  Louise
Hosey FBO Coherent.  If at the Closing the Company shall fail to tender such
Notes to you as provided above in this Section 3, or any of the conditions
specified in Section 4 shall not have been fulfilled to your satisfaction,
you shall, at your election, be relieved of all further obligations under
this Agreement, without thereby waiving any rights you may have by reason of
such failure or such nonfulfillment.

4.     CONDITIONS TO CLOSING.

       Your obligation to purchase and pay for the Notes to be sold to you at
the Closing is subject to the fulfillment to your satisfaction, prior to or at

Schedule 5.14) no Default or Event of Default shall have occurred and be
continuing.  Neither the Company nor any Subsidiary shall have entered into any

New York Insurance Law) permitting limited investments by insurance companies
without restriction as to the character of the particular investment, (ii)
not violate any applicable law or regulation (including, without limitation,

       Except as specified in Schedule 4.9, the Company shall not have changed

standing under the laws of its jurisdiction of incorporation, and is duly
qualified as a foreign corporation and is in good standing in each jurisdiction
in which such qualification is required by law, other than those jurisdictions
as to which the failure to be so qualified or in good standing could not,
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect.  The Company has the corporate power and authority to own or
hold under lease the properties it purports to own or hold under lease, to
transact the business it transacts and proposes to transact, to execute and
deliver this Agreement and the Other Agreements and the Notes and to perform the
provisions hereof and thereof.

standing under the laws of its jurisdiction of incorporation, and is duly
qualified as a foreign corporation and is in good standing in each jurisdiction
in which such qualification is required by law, other than those jurisdictions
as to which the failure to be so qualified or in good standing could not,

Adverse Effect.  The Company has the corporate power and authority to own or

       This Agreement, the Other Agreements and the Notes have been duly
authorized by all necessary corporate action on the part of the Company, and
this Agreement constitutes, and upon execution and delivery thereof each Note
will constitute, a legal, valid and binding obligation of the Company
enforceable against the Company in accordance with its terms, except as such
enforceability may be limited by (i) applicable bankruptcy, insolvency,
reorganization, moratorium or other similar laws affecting the enforcement of
creditors' rights generally and (ii) general principles of equity (regardless of
whether such enforceability is considered in a proceeding in equity or at law).


5.3    DISCLOSURE.

       The Company, through its agent, NationsBanc Montgomery Securities, LLC,
has delivered to you and each Other Purchaser a copy of a Private Placement
Memorandum, dated March 1999 (the "MEMORANDUM"), relating to the transactions

or as expressly described in Schedule 5.3, or in one of the documents,
certificates or other writings identified therein, or in the financial
statements listed in Schedule 5.5, since September 26, 1998, there has been no
change in the financial condition, operations, business or properties of the
Company or any Restricted Subsidiary except changes that individually or in the
aggregate could not reasonably be expected to have a Material Adverse Effect.
There is no fact known to the Company that could reasonably be expected to have
a Material Adverse Effect that has not been set forth herein or in the
Memorandum or in the other documents, certificates and other writings delivered
to you by or on behalf of the Company specifically for use in connection with

organization, the percentage of shares of each class of its capital stock or
similar equity interests outstanding owned by the Company and each other
Subsidiary and whether such Subsidiary is a Restricted Subsidiary or an
Unrestricted Subsidiary, (ii) of the Company's Affiliates, other than
Subsidiaries, and (iii) of the Company's directors and senior officers.

       (b)    All of the outstanding shares of capital stock or similar equity
interests of each Restricted Subsidiary shown in Schedule 5.4 as being owned by
the Company and its Restricted Subsidiaries have been validly issued, are fully
paid and nonassessable and are owned by the Company or another Restricted
Subsidiary free and clear of any Lien, except for directors qualifying shares or
any Permitted Lien.

       (c)    Each Subsidiary identified in Schedule 5.4 is a corporation or
other legal entity duly organized, validly existing and in good standing under
the laws of its jurisdiction of organization, and is duly qualified as a foreign
corporation or other legal entity and is in good standing in each jurisdiction
in which such qualification is required by law, other than those jurisdictions
as to which the failure to be so qualified or in good standing could not,
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect.  Each such Subsidiary has the corporate or other power and
authority to own or hold under lease the properties it purports to own or hold
under lease and to transact the business it transacts and proposes to transact.

       (d)    No Restricted Subsidiary is a party to, or otherwise subject to
any legal restriction or any agreement (other than this Agreement and customary
limitations imposed by corporate law statutes) restricting the ability of such
Restricted Subsidiary to pay dividends out of profits or make any other similar
distributions of profits to the Company or any of its Restricted Subsidiaries
that owns outstanding shares of capital stock or similar equity interests of
such Restricted Subsidiary.

5.5    FINANCIAL STATEMENTS.

       The Company has delivered to each Purchaser copies of the financial
statements of the Company and its Restricted Subsidiaries listed on Schedule
5.5.  All of said financial statements (including in each case the related
schedules and notes) fairly present in all material respects the consolidated
financial position of the Company and its Restricted Subsidiaries as of the
respective dates specified in such Schedule and the consolidated results of
their operations and cash flows for the respective periods so specified and have
been prepared in accordance with GAAP consistently applied throughout the
periods involved except as set forth in the notes thereto (subject, in the case
of any interim financial statements, to normal year-end adjustments).


5.6    COMPLIANCE WITH LAWS, OTHER INSTRUMENTS, ETC.

       The execution, delivery and performance by the Company of this
Agreement and the Notes will not (i) contravene, result in any breach of, or
constitute a default under, or result in the creation of any Lien in respect
of any property of the Company or any Restricted Subsidiary under, any
indenture, mortgage, deed of trust, loan, note purchase or credit agreement,
corporate charter or by-laws, or any other Material agreement or instrument
to which the Company or any Restricted Subsidiary is bound or by which the
Company or any Restricted Subsidiary or any of their respective properties
may be bound or affected, (ii) conflict with or result in a breach of any of
the terms, conditions or provisions of any order, judgment, decree, or ruling
of any court, arbitrator or Governmental Authority applicable to the Company
or any Restricted Subsidiary or (iii) violate any provision of any statute or
other rule or regulation of any Governmental Authority applicable to the
Company or any Restricted Subsidiary.


5.7    GOVERNMENTAL AUTHORIZATIONS, ETC.

       No consent, approval or authorization of, or registration, filing or
declaration with, any Governmental Authority is required in connection with the
execution, delivery or performance by the Company of this Agreement or the
Notes.


                                       5

<PAGE>

5.8    LITIGATION; OBSERVANCE OF AGREEMENTS, STATUTES AND ORDERS.

       (a)    Except as disclosed in Schedule 5.8, there are no actions, suits
or proceedings pending or, to the knowledge of the Company, threatened against
or affecting the Company or any Restricted Subsidiary or any property of the
Company or any Restricted Subsidiary in any court or before any arbitrator of
any kind or before or by any Governmental Authority that, individually or in the
aggregate, could reasonably be expected to have a Material Adverse Effect.

       (b)    Neither the Company nor any Restricted Subsidiary is in default
under any term of any agreement or instrument to which it is a party or by which
it is bound, or any order, judgment, decree or ruling of any court, arbitrator
or Governmental Authority or is in violation of any applicable law, ordinance,
rule or regulation (including without limitation Environmental Laws) of any
Governmental Authority, which default or violation, individually or in the
aggregate, could reasonably be expected to have a Material Adverse Effect.

5.9    TAXES.

       The Company and its Subsidiaries have filed all tax returns that are
required to have been filed in any jurisdiction, and have paid all taxes shown
to be due and payable on such returns and all other taxes and assessments levied
upon them or their properties, assets, income or franchises, to the extent such
taxes and assessments have become due and payable and before they have become
delinquent, except for any taxes and assessments (i) the amount of which is not
individually or in the aggregate Material or (ii) the amount, applicability or
validity of which is currently being contested in good faith by appropriate
proceedings and with respect to which the Company or a Subsidiary, as the case
may be, has established adequate reserves in accordance with GAAP or have been
determined by the Company and, to the best of the Company's knowledge, are
beyond the applicable limitations period for audit by the Internal Revenue
Service.  The Company knows of no basis for any other tax or assessment that
could reasonably be expected to have a Material Adverse Effect.  The charges,
accruals and reserves on the books of the Company and its Subsidiaries in
respect of Federal, state or other taxes for all fiscal periods are adequate.
The Federal income tax liabilities of the Company and its Subsidiaries have been
determined by the Internal Revenue Service and paid for all fiscal years up to
and including the fiscal year ended September 30, 1995.


5.10   TITLE TO PROPERTY; LEASES.

       The Company and its Restricted Subsidiaries have good and sufficient
title to their respective properties that individually or in the aggregate are
Material, to the extent reflected in the most recent audited balance sheet
referred to in Section 5.5 or purported to have been acquired by the Company or
any Restricted Subsidiary after said date (except as sold or otherwise disposed
of in the ordinary course of business), in each case free and clear of Liens
prohibited by this Agreement, except for those defects in title and Liens that,
individually or in the aggregate, could not reasonably be expected to have a
Material Adverse Effect.  All leases that individually or in the aggregate are
Material are valid and subsisting and are in full force and effect in all
material respects.


5.11   LICENSES, PERMITS, ETC.

       Except as disclosed in Schedule 5.11,

       (a)    the Company and its Restricted Subsidiaries own or possess all
licenses, permits, franchises, authorizations, patents, copyrights, service
marks, trademarks and trade names, or rights thereto, that individually or in
the aggregate are Material and necessary to operate their respective businesses,
without known conflict with the rights of others, except for any failure to own
or possess that, individually or in aggregate, could not reasonably be expected
to have a Material Adverse Effect;

       (b)    to the best knowledge of the Company, no product of the Company
infringes in any Material respect any license, permit, franchise, authorization,
patent, copyright, service mark, trademark, trade name or other right owned by
any other Person; and


                                       6

<PAGE>

       (c)    to the best knowledge of the Company, there is no Material
violation by any Person of any right of the Company or any of its Restricted
Subsidiaries with respect to any patent, copyright, service mark, trademark,
trade name or other right owned or used by the Company or any of its Restricted
Subsidiaries.

5.12   COMPLIANCE WITH ERISA.

       (a)    The Company and each ERISA Affiliate have operated and
administered each Plan in compliance with all applicable laws except for such
instances of noncompliance as have not resulted in and could not reasonably be
expected to result in a Material Adverse Effect.  Neither the Company nor any
ERISA Affiliate has incurred any liability pursuant to Title I or IV of ERISA or
the penalty or excise tax provisions of the Code relating to employee benefit
plans (as defined in Section 3 of ERISA), and no event, transaction or condition
has occurred or exists that could reasonably be expected to result in the
incurrence of any such liability by the Company or any ERISA Affiliate, or in
the imposition of any Lien on any of the rights, properties or assets of the
Company or any ERISA Affiliate, in either case pursuant to Title I or IV of
ERISA or to such penalty or excise tax provisions or to Section 401(a)(29) or
412 of the Code, other than such liabilities or Liens as would not be
individually or in the aggregate Material.

       (b)    The present value of the aggregate benefit liabilities under each
of the Plans (other than Multiemployer Plans), determined as of the end of such
Plan's most recently ended plan year on the basis of the actuarial assumptions
specified for funding purposes in such Plan's most recent actuarial valuation
report, did not exceed the aggregate current value of the assets of such Plan
allocable to such benefit liabilities, or such deficit, if any, did not exceed
5% of Consolidated Net Worth as of the end of the most recently ended fiscal
quarter of the Company.  The term "BENEFIT LIABILITIES" has the meaning
specified in section 4001 of ERISA and the terms "CURRENT VALUE" and "PRESENT
VALUE" have the meaning specified in section 3 of ERISA.

       (c)    The Company and its ERISA Affiliates have not incurred withdrawal
liabilities (and are not subject to contingent withdrawal liabilities) under
section 4201 or 4204 of ERISA in respect of Multiemployer Plans that
individually or in the aggregate are Material.

       (d)    The expected postretirement benefit obligation (determined as of
the last day of the Company's most recently ended fiscal year in accordance with
Financial Accounting Standards Board Statement No. 106, without regard to
liabilities attributable to continuation coverage mandated by section 4980B of
the Code) of the Company and its Restricted Subsidiaries is not Material or has
otherwise been disclosed in the most recent audited consolidated financial

       The Company will apply the proceeds of the sale of the Notes as set forth
in Schedule 5.14.  No part of the proceeds from the sale of the Notes hereunder

the Indebtedness of the Company or its Subsidiaries.  Neither the Company nor
any Subsidiary is in default and no waiver of default is currently in effect, in
the payment of any principal or interest on any Indebtedness of the Company or
such Subsidiary and no event or condition exists with respect to any
Indebtedness of the Company or any Subsidiary that would permit (or that with
notice or the lapse of time, or both, would permit) one or more Persons to cause
such Indebtedness to become due and payable before its stated maturity or before
its regularly scheduled dates of payment.

       (b)    Except as disclosed in Schedule 5.15, neither the Company nor any
Restricted Subsidiary has agreed or consented to cause or permit in the future
(upon the happening of a contingency or otherwise) any of its property, whether
now owned or hereafter acquired, to be subject to a Lien not permitted by

Except as otherwise disclosed to you in writing.

(a)    neither the Company nor any Restricted Subsidiary has knowledge of any
facts which would, in the aggregate, constitute the basis for any claim, public

5.19   YEAR 2000.

       The Company has initiated a review and assessment of all areas within its
and each of its Restricted Subsidiaries' businesses and operations that could be
materially adversely affected by the risk that computer applications used by the
Company or any of its Restricted Subsidiaries may be unable to recognize and
perform properly date-sensitive functions involving certain dates prior to any
date after December 31, 1999.  Based on the foregoing, the Company is taking all
steps the Company considers reasonably necessary to ensure that all computer
applications that are necessary to its or any of its Restricted Subsidiaries'
businesses and operations are able to perform properly date-sensitive functions
for all dates before and after January 1, 2000, except to the extent that any
such Year 2000 non-compliance could not reasonably be expected to have a
Material Adverse Effect.

PROVIDED that upon any partial prepayment of the Notes pursuant to Section 8.2
or purchase of the Notes permitted by Section 8.5 the principal amount of each
required prepayment of the Notes becoming due under this Section 8.1 on and
after the date of such prepayment or purchase shall be reduced in the same
proportion as the aggregate unpaid principal amount of the Notes is reduced as a
result of such prepayment or purchase.


8.2    OPTIONAL PREPAYMENTS WITH MAKE-WHOLE AMOUNT.

       The Company may, at its option, upon notice as provided below, prepay
on any Business Day all, or from time to time any part of, the Notes, in an
amount not less than 5% of the aggregate principal amount of the Notes then

be paid on the prepayment date with respect to such principal amount being
prepaid, and shall be accompanied by a certificate of a Senior Financial
Officer as to the estimated Make-Whole Amount due in connection with such
prepayment (calculated as if the date of such notice were the date of the

certificate of a Senior Financial Officer specifying the calculation of such
Make-Whole Amount as of the specified prepayment date.

<PAGE>

8.3    ALLOCATION OF PARTIAL PREPAYMENTS.

       In the case of each partial prepayment of the Notes, the principal
amount of the Notes to be prepaid shall be allocated among all of the Notes
of all Series (provided that required prepayments pursuant to Section 8.1
shall be allocated only among all of the Notes of the Series being prepaid)
at the time outstanding in proportion, as nearly as practicable, to the
respective unpaid principal amounts thereof not theretofore called for
prepayment.


8.4    MATURITY; SURRENDER, ETC.

       In the case of each prepayment of Notes pursuant to this Section 8,
the principal amount of each Note to be prepaid shall mature and become due
and payable on the date fixed for such prepayment, together with interest on
such principal amount accrued to such date and the applicable Make-Whole
Amount, if any.  From and after such date, unless the Company shall fail to
pay such principal amount when so due and payable, together with the interest
and Make-Whole Amount, if any, as aforesaid, interest on such principal
amount shall cease to accrue.  Any Note paid or prepaid in full shall be
surrendered to the Company and cancelled and shall not be reissued, and no
Note shall be issued in lieu of any prepaid principal amount of any Note.


8.5    PURCHASE OF NOTES.

       The Company will not and will not permit any Subsidiary to purchase,
redeem, prepay or otherwise acquire, directly or indirectly, any of the
outstanding Notes except upon the payment or prepayment of the Notes in
accordance with the terms of this Agreement and the Notes.  The Company will
promptly cancel all Notes acquired by it or any Subsidiary pursuant to any
payment, prepayment or purchase of Notes pursuant to any provision of this
Agreement and no Notes may be issued in substitution or exchange for any such
Notes.

8.6    MAKE-WHOLE AMOUNT.

       The term "MAKE-WHOLE AMOUNT" means, with respect to any Note, an amount
equal to the excess, if any, of the Discounted Value of the Remaining Scheduled
Payments with respect to the Called Principal of such Note over the amount of
such Called Principal, PROVIDED that the Make-Whole Amount may in no event be
less than zero.  For the purposes of determining the Make-Whole Amount, the
following terms have the following meanings:

              "CALLED PRINCIPAL" means, with respect to any Note, the principal
              of such Note that is to be prepaid pursuant to Section 8.2 or
              has become or is declared to be immediately due and payable
              pursuant to Section 12.1, as the context requires.

              "DISCOUNTED VALUE" means, with respect to the Called Principal of
              any Note, the amount obtained by discounting all Remaining
              Scheduled Payments with respect to such Called Principal from
              their respective scheduled due dates to the Settlement Date with
              respect to such Called Principal, in accordance with accepted
              financial practice and at a discount factor (applied on the same
              periodic basis as that on which interest on the Notes is payable)
              based upon the Reinvestment Yield with respect to such Called
              Principal.

              "REINVESTMENT YIELD" means, with respect to the Called Principal
              of any Note, 0.50% over the yield to maturity implied by (i) the
              yields reported, as of 10:00 A.M. (New York City time) on the
              second Business Day preceding the Settlement Date with respect to
              such Called Principal, on the display designated as "Page PX1" of
              the Bloomberg Financial Markets Services Screen (or such other
              display as may replace Page PX1 on the Bloomberg Financial Markets
              Services Screen) for actively traded U.S. Treasury securities
              having a maturity equal to the Remaining Average Life of such
              Called Principal as of such Settlement Date, or (ii) if such
              yields are not reported as of such time or the yields reported as
              of such time are not ascertainable (including by way of
              interpolation), the Treasury Constant Maturity Series Yields
              reported, for the latest day for which such yields have been so
              reported as of

                                      14
<PAGE>

              the second Business Day preceding the Settlement Date with
              respect to such Called Principal, in Federal Reserve
              Statistical Release H.15 (519) (or any comparable successor
              publication) for actively traded U.S. Treasury securities
              having a constant maturity equal to the Remaining Average Life
              of such Called Principal as of such Settlement Date.  Such
              implied yield will be determined, if necessary, by (a)
              converting U.S. Treasury bill quotations to bond-equivalent
              yields in accordance with accepted financial practice and (b)
              interpolating linearly between (1) the actively traded U.S.
              Treasury security with the duration closest to and greater than
              the Remaining Average Life and (2) the actively traded U.S.
              Treasury security with the duration closest to and less than
              the Remaining Average Life.

              "REMAINING AVERAGE LIFE"  means, with respect to any Called
              Principal, the number of years (calculated to the nearest
              one-twelfth year) obtained by dividing (i) such Called
              Principal into (ii) the sum of the products obtained by
              multiplying (a) the principal component of each Remaining
              Scheduled Payment with respect to such Called Principal by (b)
              the number of years (calculated to the nearest one-twelfth
              year) that will elapse between the Settlement Date with respect
              to such Called Principal and the scheduled due date of such
              Remaining Scheduled Payment.

              "REMAINING SCHEDULED PAYMENTS" means, with respect to the Called
              Principal of any Note, all payments of such Called Principal and
              interest thereon that would be due after the Settlement Date with
              respect to such Called Principal if no payment of such Called
              Principal were made prior to its scheduled due date, PROVIDED that
              if such Settlement Date is not a date on which interest payments
              are due to be made under the terms of the Notes, then the amount
              of the next succeeding scheduled interest payment will be reduced
              by the amount of interest accrued to such Settlement Date and
              required to be paid on such Settlement Date pursuant to
              Section 8.2 or 12.1.

              "SETTLEMENT DATE" means, with respect to the Called Principal of
              any Note, the date on which such Called Principal is to be prepaid
              pursuant to Section 8.2 or has become or is declared to be
              immediately due and payable pursuant to Section 12.1, as the
              context requires.

9.     AFFIRMATIVE COVENANTS.

       The Company covenants that so long as any of the Notes are outstanding:

9.1    COMPLIANCE WITH LAW.

       The Company will and will cause each of its Subsidiaries to comply with
all laws, ordinances or governmental rules or regulations to which each of them
is subject, including, without limitation, Environmental Laws, and will obtain
and maintain in effect all licenses, certificates, permits, franchises and other
governmental authorizations necessary to the ownership of their respective
properties or to the conduct of their respective businesses, in each case to the
extent necessary to ensure that non-compliance with such laws, ordinances or
governmental rules or regulations or failures to obtain or maintain in effect
such licenses, certificates, permits, franchises and other governmental
authorizations could not, individually or in the aggregate, reasonably be
expected to have a Material Adverse Effect.

9.2    INSURANCE.

       The Company will and will cause each of its Restricted Subsidiaries to
maintain, with financially sound and reputable insurers, insurance with respect
to their respective properties and businesses against such casualties and
contingencies, of such types, on such terms and in such amounts (including
deductibles, co-insurance and self-insurance, if adequate reserves are
maintained with respect thereto) as is customary in the case of entities of
similar size and of comparable reputations engaged in the same or a similar
business and similarly situated.


                                      15

9.3    MAINTENANCE OF PROPERTIES.

The Company will and will cause each of its Restricted Subsidiaries to maintain
and keep, or cause to be maintained and kept, their respective properties in
good repair, working order and condition (other than ordinary wear and tear), so
that the business carried on in connection therewith may be properly conducted
at all times, PROVIDED that this Section shall not prevent the Company or any
Restricted Subsidiary from discontinuing the operation and the maintenance of
any of its properties if such discontinuance is desirable in the conduct of its
business and the Company has concluded that such discontinuance could not,
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect.


9.4    PAYMENT OF TAXES AND CLAIMS.

       The Company will and will cause each of its Subsidiaries to file all tax
returns required to be filed in any jurisdiction and to pay and discharge all
taxes shown to be due and payable on such returns and all other taxes,
assessments, governmental charges, or levies imposed on them or any of their
properties, assets, income or franchises, to the extent such taxes and
assessments have become due and payable and before they have become delinquent
and all claims for which sums have become due and payable that have or might
become a Lien on properties or assets of the Company or any Subsidiary, PROVIDED
that neither the Company nor any  Subsidiary need pay any such tax or assessment
or claims if (i) the amount, applicability or validity thereof is contested by
the Company or such Subsidiary on a timely basis in good faith and in
appropriate proceedings, and the Company or a Subsidiary has established
adequate reserves therefor in accordance with GAAP on the books of the Company
or such Subsidiary or (ii) the nonfiling or nonpayment, as the case may be, of
all such taxes and assessments in the aggregate could not reasonably be expected
to have a Material Adverse Effect.


9.5    CORPORATE EXISTENCE, ETC.

       The Company will at all times preserve and keep in full force and effect
its corporate existence.  Subject to Section 10.2, the Company will at all times
preserve and keep in full force and effect the corporate existence of each of
its Restricted Subsidiaries (unless merged into the Company or a Restricted
Subsidiary) and all rights and franchises of the Company and its Restricted
Subsidiaries unless, in the good faith judgment of the Company, the termination
of or failure to preserve and keep in full force and effect such corporate
existence, right or franchise could not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect.


10.    NEGATIVE COVENANTS.

       The Company covenants that so long as any of the Notes are outstanding:

10.1   TRANSACTIONS WITH AFFILIATES.

       The Company will not and will not permit any Restricted Subsidiary to
enter into directly or indirectly any Material transaction or Material group of
related transactions (including without limitation the purchase, lease, sale or
exchange of properties of any kind or the rendering of any service) with any
Affiliate (other than the Company or another Restricted Subsidiary), except in
the ordinary course and pursuant to the reasonable requirements of the Company's
or such Restricted Subsidiary's business and upon fair and reasonable terms no
less favorable to the Company or such Restricted Subsidiary than would be
obtainable in a comparable arm's-length transaction with a Person not an
Affiliate, PROVIDED that this limitation shall not apply to the payment of
reasonable and customary regular fees to directors of the Company who are not
employees of the Company or to customary indemnity and insurance arrangements
for directors, regardless of affiliation.


10.2   MERGER, CONSOLIDATION, SALE OF ASSETS, ETC.

       (a)    The Company will not and will not permit any Restricted Subsidiary
to consolidate with or merge with any other corporation or convey, transfer or
lease substantially all of its assets in a single transaction or series of

              (i)    any Restricted Subsidiary may (x) merge or consolidate with
       or into, or convey, transfer or lease substantially all of its assets in
       a single transaction or series of transactions to, the Company, another
       Restricted Subsidiary or, in the case of a consolidation or merger, any
       other Person so long as the surviving or continuing Person is a
       Restricted Subsidiary (provided that the Company directly or indirectly
       retains at least the same ownership interest in the surviving Restricted
       Subsidiary as it held in the disappearing Restricted Subsidiary) and so
       long as in any merger or consolidation involving the Company, either (1)
       the Company shall be the surviving or continuing corporation or (2) the
       merger or consolidation is permitted by clause (ii) of this Section
       10.2(a) and (y) convey, transfer or lease all or substantially all of its
       assets to any Person in compliance with the provisions of Section
       10.2(b); and

              (ii)   the Company may consolidate or merge with or into, or
       convey, transfer or lease substantially all of its assets to, any other
       Person if,

                     (A)    in the case of a consolidation or merger, the
              surviving or continuing Person is the Company, or

                     (B)    the successor Person which results from such
              consolidation or merger or the corporation to which all or
              substantially all of the Company's assets have been conveyed,
              transferred or leased (the "SURVIVING CORPORATION") (x) shall be a
              solvent non-individual Person organized and existing under the
              laws of the United States of America or any state thereof or the
              District of Columbia, and (y) shall have executed and delivered to
              each holder of the Notes its assumption of the due and punctual
              performance and observation of all of the covenants and agreements
              in the Notes, this Agreement and the Other Agreements to be
              performed or observed by the Company, and the due and punctual
              payment of the principal of and premium, if any, and interest on
              all of the Notes, according to their tenor, and shall furnish to
              such holders an opinion of counsel reasonably satisfactory to the
              Required Holders to the effect that the instrument of assumption
              has been duly authorized, executed and delivered and constitutes
              the legal, valid and binding contract and agreement of the
              surviving corporation enforceable in accordance with its terms,
              except as enforcement of such terms may be limited by bankruptcy,
              insolvency, reorganization, moratorium and similar laws affecting
              the enforcement of creditors' rights generally and by general
              equitable principles, and

                     (C)    immediately after giving effect to any transaction
              described in clauses (A) or (B) above, no Default or Event of
              Default would exist.

              No such conveyance, transfer or lease of substantially all of the
       assets of the Company shall have the effect of releasing the Company or
       any successor Person that shall theretofore have become such in the
       manner prescribed in this Section 10.2 from its liability under this
       Agreement or the Notes.

              (b)    Subject to Section 10.2(a), the Company will not, and will
       not permit any Restricted Subsidiary to, sell, lease (as lessor),
       transfer, abandon or otherwise dispose of assets to any Person; PROVIDED
       that the foregoing restrictions do not apply to:

                     (i)    the sale, lease, transfer or other disposition of
              assets of the Company to a Wholly-Owned Restricted Subsidiary or
              of a Restricted Subsidiary to the Company or another Restricted
              Subsidiary;

                     (ii)   the sale in the ordinary course of business of (1)
              inventory held for sale, or (2) equipment, fixtures, supplies or
              materials no longer required in the operation of the business of
              the Company or any of its Restricted Subsidiaries or that is
              obsolete;

                     (iii)  the sale by the Company or any Restricted Subsidiary
              of property and the subsequent lease, as lessee, of the same
              property, within 180 days following the acquisition or
              construction of such property, PROVIDED that the rental payments
              to be made by the


                                      17
<PAGE>

              Company or such Restricted Subsidiary, discounted at a reasonable
              rate, will not exceed the fair market value of such property at
              the time of such sale;

                     (iv)   the sale of assets for cash or other property to a
              Person or Persons (other than an Affiliate) if all of the
              following conditions are met:

                            (1)    such assets (valued at net book value) do not
                     constitute a "substantial part" of the assets of the
                     Company and its Restricted Subsidiaries;

                            (2)    in the opinion of a Responsible Officer of
                     the Company, the sale is for fair value and is in the best
                     interests of the Company; and

                            (3)    immediately after the consummation of the
                     transaction and after giving effect thereto, no Default or
                     Event of Default would exist; or

                     (v)    the sale of assets meeting the conditions set forth
              in clauses (2) and (3) of subparagraph (iv) above, as long as the
              proceeds from such sale in excess of a substantial part of the
              assets of the Company and its Restricted Subsidiaries are (i)
              applied within 360 days of the date of sale of such assets to the
              acquisition of fixed assets or other property useful and intended
              to be used in the operation of the business of the Company or its
              Restricted Subsidiaries, and/or (ii) used to repay any
              Indebtedness of the Company or its Restricted Subsidiaries (other
              than Subordinated Debt, Indebtedness owing to the Company, any of
              its Subsidiaries or any Affiliate and Indebtedness in respect of
              any revolving credit or similar credit facility providing the
              Company or any of its Restricted Subsidiaries with the right to
              obtain loans or other extensions of credit from time to time,
              except to the extent that in connection with such payment of
              Indebtedness the availability of credit under such credit facility
              is permanently reduced by an amount not less than the amount of
              such proceeds applied to the payment of such Indebtedness).

              (c)    For purposes of Section 10.2(b), a sale of assets will be
       deemed to involve a "SUBSTANTIAL PART" of the assets of the Company and
       its Restricted Subsidiaries if the book value of such assets, together
       with all other assets sold during the immediately preceding 12-calendar
       month period (except those assets sold pursuant to clauses (i) or (ii) of
       Section 10.2(b)) exceeds 10% of the Consolidated Total Assets determined
       as of the end of the immediately preceding fiscal year.

10.3   LIENS.

       The Company will not and will not permit any of its Restricted
Subsidiaries to directly or indirectly create, incur or assume (upon the
happening of a contingency or otherwise) any Lien on or with respect to any
property or asset (including, without limitation, any document or instrument in
respect of goods or accounts receivable) of the Company or any such Restricted
Subsidiary, whether now owned or hereafter acquired, or any income or profits
therefrom, or assign or otherwise convey any right to receive income or profits
(unless it makes, or causes to be made, effective provision whereby the Notes
will be equally and ratably secured with any and all other obligations thereby
secured, such security to be pursuant to an agreement reasonably satisfactory to
the Required Holders and, in any such case, the Notes shall have the benefit, to
the fullest extent that, and with such priority as, the holders of the Notes may
be entitled under applicable law, of any equitable Lien on such property),

       and other similar charges or encumbrances incidental to the ownership of

12.    REMEDIES ON DEFAULT, ETC.

12.1   ACCELERATION.

       If an Event of Default with respect to the Company described in
paragraph (g) or (h) of Section 11 (other than an Event of Default described in
clause (i) of paragraph (g) or described in clause (vi) of paragraph (g) by
virtue of the fact that such clause encompasses clause (i) of paragraph (g)) has
occurred, all the Notes then outstanding shall automatically become immediately
due and payable.

       (a)    If any other Event of Default has occurred and is continuing, any
holder or holders of more than 50% in principal amount of the Notes at the time
outstanding may at any time at its or their option, by notice or notices to the
Company, declare all the Notes then outstanding to be immediately due and
payable.

       (b)    If any Event of Default described in paragraph (a) or (b) of
Section 11 has occurred and is continuing, any holder or holders of Notes at the
time outstanding affected by such Event of Default may at any time, at its or
their option, by notice or notices to the Company, declare all the Notes held by
it or them to be immediately due and payable.

       Upon any Notes becoming due and payable under this Section 12.1, whether
automatically or by declaration, such Notes will forthwith mature and the entire
unpaid principal amount of such Notes, plus (x) all accrued and unpaid interest
thereon and (y) the Make-Whole Amount determined in respect of such principal
amount (to the full extent permitted by applicable law), shall all be
immediately due and payable, in each and every case without presentment, demand,
protest or further notice, all of which are hereby waived.  The Company
acknowledges, and the parties hereto agree, that each holder of a Note has the
right to maintain its investment in the Notes free from repayment by the Company
(except as herein specifically provided for) and that the provision for payment
of a Make-Whole Amount by the Company in the event that the Notes are prepaid or
are accelerated as a result of an Event of Default, is intended to provide
compensation for the deprivation of such right under such circumstances.


                                      22
<PAGE>

12.2   OTHER REMEDIES.

       If any Default or Event of Default has occurred and is continuing, and
irrespective of whether any Notes have become or have been declared immediately
due and payable under Section 12.1, the holder of any Note at the time
outstanding may proceed to protect and enforce the rights of such holder by an
action at law, suit in equity or other appropriate proceeding, whether for the
specific performance of any agreement contained herein or in any Note, or for an
injunction against a violation of any of the terms hereof or thereof, or in aid
of the exercise of any power granted hereby or thereby or by law or otherwise.


12.3   RESCISSION.

       At any time after any Notes have been declared due and payable pursuant
to clause (b) or (c) of Section 12.1, the holders of more than 50% in principal
amount of the Notes then outstanding, by written notice to the Company, may
rescind and annul any such declaration and its consequences if (a) the Company
has paid all overdue interest on the Notes, all principal of and Make-Whole
Amount, if any, on any Notes that are due and payable and are unpaid other than
by reason of such declaration, and all interest on such overdue principal and
Make-Whole Amount, if any, and (to the extent permitted by applicable law) any
overdue interest in respect of the Notes, at the Default Rate, (b) all Events of
Default and Defaults, other than non-payment of amounts that have become due
solely by reason of such declaration, have been cured or have been waived
pursuant to Section 17, and (c) no judgment or decree has been entered for the
payment of any monies due pursuant hereto or to the Notes.  No rescission and
annulment under this Section 12.3 will extend to or affect any subsequent Event
of Default or Default or impair any right consequent thereon.


12.4   NO WAIVERS OR ELECTION OF REMEDIES, EXPENSES, ETC.

       No course of dealing and no delay on the part of any holder of any Note
in exercising any right, power or remedy shall operate as a waiver thereof or
otherwise prejudice such holder's rights, powers or remedies.  No right, power
or remedy conferred by this Agreement or by any Note upon any holder thereof
shall be exclusive of any other right, power or remedy referred to herein or
therein or now or hereafter available at law, in equity, by statute or
otherwise.  Without limiting the obligations of the Company under Section 15,
the Company will pay to the holder of each Note on demand such further amount as
shall be sufficient to cover all costs and expenses of such holder incurred in
any enforcement or collection under this Section 12, including, without
limitation, reasonable attorneys' fees, expenses and disbursements.

the registration and registration of transfers of Notes.  The name and address
of each holder of one or more Notes, each transfer thereof and the name and
address of each transferee of one or more Notes shall be registered in such
register.  Prior to due presentment for registration of transfer, the Person in
whose name any Note shall be registered shall be deemed and treated as the owner

affected by any notice or knowledge to the contrary.  The Company shall give to
any holder of a Note that is an Institutional Investor promptly upon request
therefor, a complete and correct copy of the names and addresses of all
registered holders of Notes.

for registration of transfer, duly endorsed or accompanied by a written
instrument of transfer duly executed by the registered holder of such Note or
his attorney duly authorized in writing and accompanied by the address for
notices of each transferee of such Note or part thereof), the Company shall
execute and deliver, at the Company's expense (except as provided below), one or
more new Notes (as requested by the holder thereof) in exchange therefor, in an
aggregate principal amount equal to the unpaid principal amount of the
surrendered Note.  Each such new Note shall be payable


                                      23
<PAGE>

to such Person as such holder may request and shall be substantially in the
form of Exhibit 1.  Each such new Note shall be dated and bear interest from
the date to which interest shall have been paid on the surrendered Note or
dated the date of the surrendered Note if no interest shall have been paid
thereon.  The Company may require payment of a sum sufficient to cover any
stamp tax or governmental charge imposed in respect of any such transfer of
Notes.  Notes shall not be transferred in denominations of less than
$100,000, PROVIDED that if necessary to enable the registration of transfer
by a holder of its entire holding of Notes, one Note may be in a denomination
of less than $100,000.  Any transferee, by its acceptance of a Note
registered in its name (or the name of its nominee), shall be deemed to have
made the representations set forth in Sections 6.1 and 6.2.


13.3   REPLACEMENT OF NOTES.

       Upon receipt by the Company of evidence reasonably satisfactory to it of
the ownership of and the loss, theft, destruction or mutilation of any Note

such Institutional Investor of such ownership and such loss, theft, destruction
or mutilation), and


       (a)    in the case of loss, theft or destruction, of indemnity reasonably
satisfactory to it (PROVIDED that if the holder of such Note is, or is a nominee
for, an original Purchaser or another holder of a Note with a minimum net worth
of at least $100,000,000, such Person's own unsecured agreement of indemnity
shall be deemed to be satisfactory), or

       (b)    in the case of mutilation, upon surrender and cancellation
thereof, the Company at the expense of the requesting holder shall execute and
deliver, in lieu thereof, a new Note, dated and bearing interest from the date
to which interest shall have been paid on such lost, stolen, destroyed or
mutilated Note or dated the date of such lost, stolen, destroyed or mutilated
Note if no interest shall have been paid thereon.

14.    PAYMENTS ON NOTES.

a bank or trust company in such jurisdiction.


14.2   HOME OFFICE PAYMENT.

       So long as you or your nominee shall be the holder of any Note, and

Make-Whole Amount, if any, and interest by the method and at the address
specified for such purpose below your name in Schedule A, or by such other
method or at such other address as you shall have from time to time specified to
the Company in writing for such purpose, without the presentation or surrender
of such Note or the making of any notation thereon, except that upon written
request of the Company made concurrently with or reasonably promptly after
payment or prepayment in full of any Note, you shall surrender such Note for
cancellation, reasonably promptly after any such request, to the Company at its
principal executive office or at the place of payment most recently designated
by the Company pursuant to Section 14.1.  Prior to any sale or other disposition
of any Note held by you or your nominee you will, at your election, either
endorse thereon the amount of principal paid thereon and the last date to which
interest has been paid thereon or surrender such Note to the Company in exchange
for a new Note or Notes pursuant to Section 13.2.  The Company will afford the
benefits of this Section 14.2 to any Institutional Investor that is the direct
or indirect transferee of any Note purchased by you under this Agreement and
that has made the same agreement relating to such Note as you have made in this

       (a)    SOLICITATION.  The Company will provide each holder of the Notes

enable such holder to make an informed and considered decision with respect to
any proposed amendment, waiver or consent in respect of any of the provisions
hereof or of the Notes.  In any event, 30 days shall be deemed to constitute
sufficient notice.  The Company will deliver executed or true and correct copies

the requisite holders of Notes.

       (b)    PAYMENT.  The Company will not directly or indirectly pay or cause
to be paid any remuneration, whether by way of supplemental or additional
interest, fee or otherwise, or grant any security, to any holder of Notes as
consideration for or as an inducement to the entering into by any holder of

waiver will extend to or affect any obligation, covenant, agreement, Default or
Event of Default not expressly amended or waived or impair any right consequent
thereon.  No course of dealing between the Company and the holder of any Note
nor any delay in exercising any rights hereunder or under any Note shall operate
as a waiver of any rights of any holder of such Note.  As used herein, the term
"THIS AGREEMENT" and references thereto shall mean this Agreement as it may from
time to time be amended or supplemented.


17.4   NOTES HELD BY COMPANY, ETC.

                    MATTERS TO BE COVERED IN OPINION OF COUNSEL
                                  TO THE COMPANY



1.     The Company has been duly incorporated and is validly existing in good
standing under the laws of the State of Delaware and is duly licensed or
qualified and is in good standing as a foreign corporation in each jurisdiction
in which the character of the properties owned or leased by it or the nature of
the business transacted by it makes such licensing or qualification necessary.

2.     Each Restricted Subsidiary has been duly incorporated and is validly
existing in good standing under the laws of its jurisdiction of incorporation
and is duly licensed or qualified and is in good standing in each jurisdiction
in which the character of the properties owned or leased by it or the nature of
the business transacted by it makes such licensing or qualification necessary.
All of the outstanding shares of capital stock of each such Restricted
Subsidiary have been duly issued, are fully paid and non-assessable and are
owned of record by the Company, by one or more Restricted Subsidiary, or by the
Company and one or more Restricted Subsidiaries.

3.     The Company has the corporate power to execute and deliver the Agreement
and the Other Agreements (the "AGREEMENTS"), to perform its obligations set
forth in each of the Agreements and  to issue and sell the Notes and to perform
its obligations set forth therein.

4.     The execution, delivery and performance of each of the Agreements and the
Notes have been duly authorized by all necessary corporate action on the part of
the Company, and each of the Agreements and the Notes have been duly executed
and delivered by the Company.

5.     The Agreements and the Notes constitute the legally valid and binding
obligations of the Company, enforceable against the Company in accordance with
their respective terms, except as may be limited by bankruptcy, insolvency,
reorganization, moratorium or similar laws relating to or affecting creditors'
rights generally (including, without limitation, fraudulent conveyance laws) and
by general principles of equity including, without limitation, concepts of
materiality, reasonableness, good faith and fair dealing and the possible
unavailability of specific performance or injunctive relief, regardless of
whether considered in a proceeding in equity or at law.

6.     The Company's execution and delivery of, and performance of its
obligations under the Agreements and the Notes do not and will not (i) violate
the Company's Articles or Certificate of Incorporation or Bylaws, (ii) violate,
breach or result in a default under, or result in the imposition of any Lien
upon any property of the Company pursuant to, any existing obligation of or
restriction on the Company under any other Material agreement, instrument or
indenture listed on Schedule I hereto, (iii) breach or otherwise violate any
existing obligation of or restriction on the Company under any order, judgment
or decree of any California or Federal court or governmental authority binding
on the Company listed on Schedule II hereto, or (iv) violate any California or
Federal law or regulation.

7.     No order, consent, permit or approval of any California or Federal
governmental authority is required on the part of the Company to issue and sell
the Notes or for the execution and delivery of, and performance of the Company's
obligations under, the Agreements and the Notes.

8.     To our knowledge, there is no action, suit or proceeding pending against
or threatened against or affecting the Company or any Restricted Subsidiary
before any court, governmental or regulatory authority or arbitrator, which
seeks to affect the enforceability of the Agreements or the Notes or which could
reasonably be expected to have a Material Adverse Effect.


                                      41
<PAGE>

9.     Assuming the accuracy of (i) the Company's representations in the first
sentence of Section 5.13 of the Agreements and (ii) your representations in
Section 6.1 of the Agreements, it is not necessary in connection with the
execution and delivery of the Notes under the circumstances contemplated by the
Note Purchase Agreements to register the Notes under the Securities Act of 1933,
as amended, or to qualify an indenture in respect thereof under the Trust
Indenture Act of 1939, as amended.

10.    Neither the extension of credit nor the use of proceeds provided in the
Agreements if made in accordance with the terms thereof will violate Regulations
T, U or X of the Board of Governors of the Federal Reserve System.

11.    The Company is not an "investment company" or a company "controlled" by
an "investment company" within the meaning of the Investment Company Act of
1940, as amended.
