PART I

ITEM 1.  BUSINESS

COMPANY OVERVIEW

        EMCORE Corporation (together with its subsidiary, "EMCORE" or the
"Company"), founded in 1984, designs and develops compound semiconductor
materials and process technology and is a leading manufacturer of production
systems used to fabricate compound semiconductor wafers. The Company provides
its customers, both in the U.S. and internationally, with materials science
expertise, process technology and compound semiconductor production systems
that enable the manufacture of commercial volumes of high-performance
electronic and optoelectronic devices. In 1996, in response to the growing need
of its customers to cost effectively get to market faster with high volumes of
new and improved high-performance products, the Company expanded its product
offerings to include the design, development and production of compound
semiconductor wafers and package-ready devices.

INDUSTRY OVERVIEW

        Recent advances in information technologies have created a growing need
for power efficient, high-performance electronic systems that operate at very
high frequencies, have increased storage capacity and computational and display
capabilities, and can be produced cost-effectively in commercial volumes. In
the past, electronic systems manufacturers have relied on advances in silicon
semiconductor technology to meet many of these demands. However, the newest
generation of high-performance electronic and optoelectronic applications
require certain functions which are generally not achievable using
silicon-based components. To address these market demands, electronic system
manufacturers are increasingly incorporating new electronic and optoelectronic
devices into their products in order to improve performance or enable new
applications.

        Compound semiconductors have emerged as an enabling technology to meet
the complex requirements of today's advanced information systems. Compound
semiconductor devices can be used to perform individual functions as discrete
devices, such as high-brightness light-emitting diodes ("HB LEDs"), lasers and
solar cells, or can be combined into integrated circuits, such as transmitters,
receivers and alpha-numeric displays. Many compound semiconductor materials
have unique physical properties that allow electrons to move at least four
times faster than through silicon-based devices. This higher electron mobility
enables a compound semiconductor device to operate at much higher speeds than
silicon devices with lower power consumption and less noise and distortion. In
addition, unlike silicon-based devices, compound semiconductor devices have
optoelectronic capabilities that enable them to emit and detect light. As a
result, electronics manufacturers are increasingly integrating compound
semiconductor



                                      -2-
<PAGE>   3


devices into their products in order to achieve higher performance in a wide
variety of applications, including satellite, fiberoptic and wireless
communications, telecommunications, computers, and consumer and automotive
electronics.

        Historically, developers of compound semiconductor devices have met
capacity needs with in-house systems and technologies. However, the
requirements for the production of commercial volumes of high-performance
compound semiconductor devices have often exceeded the capabilities of such
in-house solutions. The Company believes that wafers fabricated using metal
organic chemical vapor deposition ("MOCVD") possess better uniformity, as well
as better optical and electronic properties, than wafers fabricated by
traditional methods. The Company believes that its proprietary TurboDiscTM
MOCVD system provides a low cost of ownership and is the critical enabling
process step in the volume manufacture of high-performance electronic and
optoelectronic devices. The Company works closely with its customers in
designing and developing materials processes to be used in production systems
for its customers' end-use applications. The Company has sold more than 225
systems worldwide to a broad base of leading electronics manufacturers,
including: Spectrolab, Inc. (a subsidiary of Hughes Electronics Company,
"Hughes-Spectrolab"), General Motors Corp. ("General Motors"), Hewlett Packard
Co., Honeywell, Inc., Lucent Technologies, Inc., Rockwell International Corp.
("Rockwell"), Samsung Co., Siemens AG, L.M. Ericsson AB, Texas Instruments Inc.
and 13 of the largest electronics manufacturers in Japan.

        SATELLITE COMMUNICATIONS. Compound semiconductor solar cells are used
to power satellites because they are more tolerant to radiation levels in space
and have higher power-to-weight ratios than silicon-based solar cells, thereby
increasing satellite life and payload capacity. Compound semiconductor devices
are also used in ultra-high frequency satellite up-converters and
down-converters to cost-effectively deliver information to fixed and mobile
users over wide geographic areas. The Company is developing high efficiency
gallium arsenide solar cells to increase satellite payload capacity and reduce
launch weight.

        DATA COMMUNICATIONS. To accommodate the exponential growth in voice,
data and video traffic resulting from the Internet and networking generally,
telecommunications companies, data communications, switch and router companies
and Internet service providers are relying on fiber optic networks utilizing
high-speed switching technologies to increase transmission rates. New and
emerging standards, including Gigabit Ethernet, asynchronous transfer mode
("ATM") and FibreChannel, provide a solid infrastructure for bringing fiber
optics into these networks. As these standards are rapidly deployed in networks
worldwide, the need for high-speed fiber optic technologies to support them
grows proportionally. The Company supports these standards through its recently
announced high speed vertical cavity surface-emitting laser ("VCSEL")
components, arrays, and subassemblies developed to meet the needs of these and
other demanding applications. 

        TELECOMMUNICATIONS. The most common deployment of fiber optic equipment
is currently in high capacity trunk lines for long distance and inter-exchange
telecommunications. Long distance carriers continue to upgrade their networks to
incorporate more and more fiber optic technology. The market for
telecommunications will continue to expand as carriers convert copper
interconnections to higher capacity fiber optic cable. In addition to extending
and expanding the existing infrastructure, the trend is moving to higher and
higher bit rate connections - from 2.5Gbs to 10Gbs, driving the need for greater
sophistication in laser and compound semiconductor technology. The Company's
in-depth material science expertise and its recently announced achievements in
high speed microlasers allow the Company to offer fully integrated VCSEL
component and array solutions in the industry and enable the development of
1300nm VCSELs, which will help make low cost, high performance broadband access
and fiber-in-the-loop possible.

        WIRELESS COMMUNICATIONS. Compound semiconductor devices have multiple
applications in wireless communication products, including cellular telephones,
pagers, personal communication systems ("PCS") handsets, direct broadcast
systems ("DBS") and global positioning systems. Compound semiconductor devices
are used in high frequency transmitters, receivers and power amplifiers to
increase capacity, improve signal to noise performance and lower power
consumption, which in turn reduces network congestion, increases roaming range
and extends battery life. In addition, HB LEDs are used in electronic displays
on these products in order to reduce size, weight and power consumption and to
improve display visibility.



                                      -3-
<PAGE>   4


        COMPUTERS AND PERIPHERALS. As computer manufacturers continue to
integrate faster and faster microprocessors into their systems designs, the gap
between the internal central processing unit ("CPU") speed and the external bus
continues to grow. As this gap increases, computer suppliers are concerned less
with processor speed, and more with overall system performance. Computer
manufacturers are increasingly looking to compound semiconductor products and
specifically to on board photonic interconnects to greatly enhance system
performance. Several major computer and microprocessor manufacturers have
expressed interest in integrating the Company's VCSEL technology into their next
generation products.

        CONSUMER ELECTRONICS. Consumer electronics manufacturers are using
compound semiconductor devices to improve the performance of many existing
products and to develop new applications. For example, next generation compact
disc players are utilizing shorter wavelength compound semiconductor lasers to
read and record information on high density digital videodiscs ("DVDs") which
store at least four times more information than a conventional compact disc. In
addition, compound semiconductor devices are increasingly being used in
advanced display technologies. Ultra-thin LED flat panel displays are being
used in a variety of applications, including point-of-purchase displays and
outdoor advertising with live-action billboards, and are being developed for
use in laptop computers and flat panel television screens. Gallium nitride
based HB LEDs are being developed for lighting applications that in the future
may replace incandescent light bulbs.

        AUTOMOTIVE ELECTRONICS. Compound semiconductor devices are increasingly
being used by automotive manufacturers to improve vehicle performance while
reducing weight and costs through lower power consumption. These devices are
utilized in a wide variety of applications, including dashboard displays,
indicator lights, engine sensors, anti-lock braking systems and other
electronic systems. In addition, the Company believes that the use of
electronic components within automobiles is likely to increase as manufacturers
design vehicles to comply with state and federal environmental and safety
regulations. Automotive production cycles generally last three to five years,
providing a relatively predictable source of demand for compound semiconductor
devices once an electronic component is designed into a specific vehicle model.

        The high-performance characteristics of compound semiconductors,
combined with the requirements of advanced information systems, have led to the
widespread deployment of compound semiconductor devices within a broad range of
electronic systems. The Company believes that the following factors have
resulted in an increased demand for compound semiconductor production systems,
wafers and devices which enable electronic systems manufacturers to reach the
market faster with high volumes of high-performance products and applications:

         o        Launch of new wireless services such as PCS and wireless high
                  speed data systems;

         o        Rapid build-out of satellite communications systems;

         o        Widespread deployment of fiber optic networks and the
                  increasing use of optical systems;

         o        Increasing use of infrared emitters and optical detectors in
                  computer systems;

         o        Emergence of advanced consumer electronics applications, such
                  as DVDs, flat panel displays and lighting; and,

         o        Increasing use of high-performance electronic devices in
                  automobiles.

THE EMCORE SOLUTION

        EMCORE provides its customers with materials science expertise, process
technology and MOCVD production systems that enable the manufacture of
commercial volumes of high-performance compound semiconductor wafers and
devices. EMCORE believes that its proprietary TurboDiscTM deposition technology
makes possible one of the most cost-effective production systems for the
commercial volume manufacture of high-performance compound semiconductor wafers
and devices. EMCORE is capitalizing on its technology base to address the
critical need of electronics manufacturers to cost-effectively get to market

                                      -4-
<PAGE>   5


science expertise uniquely position the Company to become a valuable source for
a broad array of solutions for the compound semiconductor industry.

STRATEGY

        The Company believes that its close collaborations with its customers
over the past fourteen years have contributed to its position in the MOCVD
process technology and production systems market. The Company's objective is to
capitalize on this position to become a leading supplier of compound
semiconductor wafers and package-ready devices. The key elements of the
Company's strategy include:

        PROVIDE COMPLETE COMPOUND SEMICONDUCTOR SOLUTIONS. The Company's
vertically-integrated product offerings allow it to provide complete compound
semiconductor solutions to a broad range of electronics manufacturers in order
to meet their diverse technology requirements. The Company plans to capitalize
on the growing need of electronics manufacturers to reach the market faster and
more cost-efficiently with high volumes of end products. The Company assists
its customers with device design, process development and optimal configuration
of production systems. Moreover, the Company can also serve its customers as a
reliable source for high-volume production of wafers or devices. Through its
materials science expertise, process technology and commercial production
systems, the Company intends to become an integral part of its customers'
compound semiconductor product life cycle.

        FORM STRATEGIC RELATIONSHIPS WITH CUSTOMERS. By developing enabling
technologies, the Company seeks to form strategic alliances with its customers
in order to obtain long-term development and high volume production contracts.
For example, the Company currently has a strategic relationship with General
Motors under which it has developed and enhanced the device structure and
production process for, and is manufacturing and shipping Magneto Resistive
Sensors ("MR Sensors") products for use in General Motors' automotive
applications. During fiscal 1998, the Company formed a joint venture with
Uniroyal Technology Corporation ("UTC"), and in November 1998, it also formed
joint ventures with Optek Technology, Inc. and Union Miniere Inc. Additionally,
the Company has entered into strategic agreements with AMP Incorporated, Space
Systems/Loral ("Loral") and Lockheed Martin Corporation. The Company intends to
actively seek similar strategic relationships with other key customers in order
to further expand its technological and production base.

        EXPAND TECHNOLOGY LEADERSHIP. The Company has developed and optimized
its compound semiconductor processes and has developed higher performance
production systems through substantial investments in research and development.
The Company works closely with its customers to identify specific performance
criteria in its production systems, wafers and package-ready devices. The
Company intends to continue to expend substantial resources in research and
development in order to enhance the performance of its production systems and
to further expand its process and materials science expertise, including the
development of new low cost, high volume wafers and package-ready devices for
its customers.

STRATEGIC INITIATIVES

        Throughout fiscal 1998, the Company has taken steps or formed strategic
relationships to take advantage of market opportunities. In December 1997, the
Company acquired MicroOptical Devices, Inc. ("MODE"). At the date of
acquisition, MODE (a development stage company) was substantially dedicated to
the research and development of enabling compound semiconductor technologies. In
February 1998, MODE announced its first commercial high speed laser
(Gigalase(TM)) and thereafter commenced commercial volume shipments. Having
achieved commercial product development, MODE now designs, develops and markets
high-quality VCSEL optical components and subassemblies. The Company's
technology is expected to enable significant performance and cost improvements
in optoelectronic systems. VCSELs offer significant advantages over traditional,
edge-emitting laser diodes, including: ultra high modulation rates, low power
consumption, high coupling efficiencies and reduced complexity and cost of
packaging. VCSELs represent a revolutionary approach to the fabrication of
semiconductor lasers and enhance the performance and cost-effectiveness of
communications equipment, computer systems and many other electronic systems
using lasers. As a result, leading electronics systems manufacturers are
integrating VCSELs into a broad array of end-market applications including
Internet access, digital cross connect telecommunications switches, DVD,
fiberoptic switching and routing, such as Gigabit Ethernet. In addition, VCSEL
technology is being evaluated for incorporation into multi-layered printed
circuit boards in order to greatly increase the speed at which on-board
components interface. The Company believes that utilizing VCSELs for
chip-to-chip and board-to-board data transfer



                                      -5-
<PAGE>   6


will significantly reduce the performance gap between the frequency of the
microprocessor and other components within computer systems.

        In addition to the MODE acquisition, the Company launched three joint
ventures during the past twelve months. In July 1998, the Company formed and is
a minority investor in Uniroyal Optoelectronics, LLC, a joint venture with UTC
to manufacture, sell and distribute HB LEDs. The global demand for HB LEDs is
experiencing rapid growth because LEDs have a long useful life (ten years) and
consume far less power than incandescent/fluorescent lighting.

        In November 1998, the Company formed a joint venture with Optek
Technology, Inc., a packager and distributor of optoelectronic devices including
sensors, to market an expanded line of MR Sensors to the automotive and related
industries. The "Emtek" joint venture combines the Company's strength in
producing a package-ready die with Optek's strength in packaging and
distribution thus enabling the Company to offer off-the-shelf products which
should enhance market penetration.

        Also in November 1998, the Company formed a joint venture ("Umcore") in
a partnership with Union Miniere Inc. to explore and develop alternate uses of
germanium using the Company's material science and production platform
expertise.

        In November 1998, the Company signed a four year Long Term Purchase
Agreement (the "Long Term Purchase Agreement") with Loral, a wholly owned
subsidiary of Loral Space & Communications. Under the Long Term Purchase
Agreement, once EMCORE completes Loral's space qualification and test
procedures, the Company will supply Loral with compound semiconductor high
efficiency gallium arsenide solar cells for Loral's satellite requirements.
Subject to the foregoing requirements, the Company received an initial purchase
order for $5.25 million of solar cells.

        In September 1998, the Company entered into an agreement with Lockheed
Martin Missiles and Space ("LMMS"), a strategic business unit of Lockheed
Martin Corporation, for the technical management and support of a LMMS and
Sandia National Laboratory ("Sandia") Cooperative Research and Development
Agreement ("CRADA") for the advancement, transfer and commercialization of a
new compound semiconductor high efficiency solar cell. Pursuant to this
strategic agreement, (i) LMMS will grant the Company a sub-license for all
CRADA related intellectual property developed on behalf of and in conjunction
with LMMS and (ii) the Company and LMMS will jointly qualify and validate the
high efficiency solar cells for operational satellite use. The Company has also
received a $2.5 million contract under the U.S. Air Force's Broad Agency
Announcement ("BAA") Program for the development of high efficiency advanced
solar cells.

        In September 1998, the Company signed a four year purchase agreement
with AMP Incorporated to provide high speed VCSELs. AMP Incorporated presently
uses the Company's VCSEL's in transceivers for Gigabit Ethernet applications.

        In October 1998, the Company opened a new facility, EMCOREwest, in
Sandia Science and Technology Park, Albuquerque, New Mexico. The Company plans a
three-phase construction project which will allow the facility to expand from an
initial 50,000 square feet in October 1998 to 70,000 square feet by 2002.
Production of wafers and devices at EMCOREwest is scheduled to begin in the
second calendar quarter of 1999. In connection with the construction of this
facility, the City of Albuquerque has issued a $55 million Industrial Revenue
Bond (the "IRB") to the Company, which provides the Company with New Mexico
tax-exempt status on the property and the purchase of equipment and supplies.
The Company estimates that total tax savings over the 20-year life of the bond
will exceed $10.0 million. MODE also completed the build-out of its fabrications
space in Albuquerque, New Mexico with an additional 20,000 square feet of
cleanroom and test facilities.

RECENT DEVELOPMENTS

        On June 22, 1998, the Company entered into an $8.0 million revolving
loan agreement (the "1998 Agreement") with First Union National Bank (the
"Bank") which expires December 31, 1999. The 1998 Agreement bears interest at a
rate equal to one-month LIBOR plus three quarters of one percent per annum (6.4%
at September 30, 1998). The 1998 Agreement is guaranteed by the Company's
Chairman and Chief Executive Officer. In exchange for guaranteeing the facility,
the Chairman and the Chief Executive Officer were granted an aggregate of
284,684 common stock purchase warrants exercisable at $11.375 per share until
May 1,



                                      -6-
<PAGE>   7


2001. These warrants are callable at the Company's option at $0.85 per warrant
at such time as the Company's Common Stock has traded at or above 150% of the
exercise price for a period of 30 days. The Company borrowed $5.0 million on
June 22, 1998 and the remaining $3.0 million on July 10, 1998.

        On September 17, 1998, the Company borrowed $7.0 million from its
Chairman. The loan bears interest at 9.75% per annum. In addition, on October
22, 1998 the Company borrowed an additional $1.5 million from its Chairman on
identical terms. The entire sum of $8.5 million borrowed from the Chairman plus
interest was repaid from the proceeds of the Private Placement (defined below).

        On November 30, 1998, the Company completed a private placement (the
"Private Placement") of an aggregate of 1,550,000 shares of Series I Redeemable
Convertible Preferred Stock (the "Series I Preferred Stock") to Hakuto Co.,
Ltd. ("Hakuto"), Union Miniere Inc. ("UMI") and UTC. The net proceeds to the
Company from the Private Placement were approximately $21.2 million which has
been used (i) to repay $8.5 million of debt, plus interest, to the Company's
Chairman of the Board, Dr. Thomas Russell, (ii) to fund the Company's $5.0
million portion of a joint venture between the Company and UTC to develop and
manufacture HB LEDs and (iii) to fund the Company's $600,000 portion of a
research and development joint venture with UMI to develop alternative
applications for germanium substrates. The remaining net proceeds from the
Private Placement will be used to acquire capital equipment for the Company's
new Albuquerque, New Mexico manufacturing facility and for working capital.

        Effective as of November 30, 1998, the Company and the Bank have
renewed the Company's $10.0 million credit facility (the "1997 Agreement") with
the Bank, which, as amended, will expire on October 1, 1999. In connection with
the amendment of the 1997 Agreement, Thomas Russell agreed to provide a
guarantee in the event the Company does not meet certain financial covenants by
May 15, 1999.

        The Company has recorded a net loss in each of the third and fourth
quarters of fiscal 1998 due primarily to the adverse effect of work-stoppage
strikes at General Motors, a decline in systems sales particularly in Asia
related to the Asian financial crisis as well as a general slowdown in the
semiconductor market overall, a slower than expected ramp-up in production at
MODE and increased research and development spending. The Company expects to
post losses for the next two fiscal quarters.

PRODUCTS

        PRODUCTION SYSTEMS AND MATERIALS PROCESSES. The Company is a leading
supplier of MOCVD compound semiconductor production systems, and, in 1996, had
a 23% share of this market according to VLSI Research Inc. which regularly
publishes research on this market. The Company has shipped more than 225
systems to date and believes that its TurboDiscTM systems offer significant
cost advantages over competing systems. The Company believes that its MOCVD
production systems produce materials with superior uniformity of thickness,
electrical properties and material composition. EMCORE has a variety of models
that are optimized for the application and throughput of the customer. The
Company believes that the high throughput capabilities of its TurboDiscTM
systems enhances the low cost manufacture of compound semiconductor materials
as well as superior reproducibility of thickness, composition, electrical
profiles and layer accuracy required for electronic and optoelectronic devices.
The Company's production systems also achieve a high degree of reliability with
an average time available for production, based on customer data, of
approximately 95%.

        WAFER AND DEVICE FABRICATION. Since its inception, the Company has
worked closely with its customers in designing and developing materials
processes to be used in production systems for its customers' end-use
applications. Recently, the Company has begun to leverage its process and
materials science knowledge base to manufacture wafers and package-ready
devices in its own facility. The Company's expansion into wafer and
package-ready device production was spurred almost entirely by requests from
customers whose epitaxial wafer needs exceed their available in-house
production capabilities. The Company fabricates wafers and package-ready
devices at its facilities in Somerset, New Jersey and Albuquerque, New Mexico
and has a combined clean room area totaling approximately 12,000 square feet.

        The Company is working with its customers to design, engineer and
manufacture commercial quantities of wafers and/or package-ready compound
semiconductor devices such as MR Sensors, HBTs, HEMTs, FETs, HB LEDs, VCSELs,
solar cells and other electronic and optoelectronic devices.



                                      -7-

        MR SENSORS. In January 1997, the Company initiated shipments of
compound semiconductor MR Sensors using indium antimonide-based epi-materials.
The technology is licensed to the Company from General Motors. The primary user
of the product has to date been General Motors Powertrain with over five
million devices delivered as of September 30, 1998 for crank and cam speed and
position sensing applications for three engine builds. In November 1998, the
Company formed a joint venture with Optek Technology, Inc. to market an
expanded line of MR Sensors to the automotive and related industries.

        HIGH EFFICIENCY SOLAR CELLS. The Company is working closely with
several large telecommunications concerns to assist these customers in
developing solar cell and other process technology for use on their
communications satellites. After extensive working collaborations, the Company
has developed the materials process and a production system for solar cell
materials with efficient performance characteristics. As a result of this
collaboration, the Company's technology has produced gallium arsenide solar
cells that are not only approximately 50% more efficient in light-to-power
conversion than silicon-based solar cells but also are more
radiation-resistant. The resulting advance allows a satellite manufacturer to
increase the useful life and payload capacity of its satellites. Over the last
two years, the Company's customers have purchased several MOCVD production
systems for this purpose. In December 1998, the Company signed the Long Term
Purchase Agreement with Loral under which the Company will supply Loral with
compound semiconductor high-efficiency gallium arsenide solar cells for Loral's
satellites.

        VCSELS. In February 1998, the Company, through its wholly-owned
subsidiary MODE, annouced its first commercial high speed laser and has
commenced commercial volume customer shipments. The Company now designs,
develops and markets optical VCSEL components, arrays and subassemblies, which
utilize compound semiconductor microlaser diodes that emit light vertically from
the surface of a fabricated wafer. The Company believes the advantage of its
VCSELs include ultra high modulation rates for advanced information processing,
low power consumption, high fiber optic coupling efficiencies, circular output
beams and photolithographically defined geometrics. The Company works closely
with original equipment manufacturers ("OEMs") to incorporate their design
requirements into the Company's VCSEL technology and test methodologies. In
September 1998, MODE formed a strategic alliance with AMP Incorporated to
develop and market a family of optical transceivers for the Gigabit Ethernet,
FibreChannel and ATM markets. These transceivers incorporate specific design
requirements into the processes and test methodologies of the Company's VCSEL
components.

        HB LEDS. Early in 1998 the Company formed a joint venture with UTC to
manufacture, sell and distribute HB LEDs. The global demand for HB LEDs is
experiencing rapid growth because LEDs have a long useful life (ten years) and
consume far less power than incandescent/ fluorescent lighting. The Company
believes it is the leading supplier of gallium nitride based MOCVD systems used
to produce blue and green HB LEDs.

CUSTOMERS

        The Company's customers include several of the largest semiconductor,
telecommunications and computer manufacturing companies in the world. In fiscal
year 1996, only one customer accounted for more than 10% of the Company's
revenues; sales to this customer accounted for 23.6% of the Company's revenues
in fiscal 1996. For the fiscal year 1997, two customers each accounted for more
than 10% of the Company's revenues; sales to these customers each accounted for
15.0% and 10.2% of the Company's revenues during fiscal year 1997. For fiscal
year 1998, two customers accounted for more than 10% of the Company's revenues;
sales to these customers accounted for 17.3% and 12.8% of the Company's
revenues during fiscal year 1998.

SALES AND MARKETING

        The Company markets and sells its products through its direct sales
force in Europe, North America, Taiwan and through representatives and
distributors in the rest of Asia. To market and service its systems in China,
Japan and Singapore, the Company relies on a single marketing, distribution and
service provider, Hakuto. The Company's agreements with Hakuto have a term of
ten years, expiring March 2008. Hakuto has exclusive distribution rights for
the Company's products in Japan. Hakuto has marketed and serviced the Company's
products since 1988, is a minority shareholder in the Company, and the
President of Hakuto is a member of the Company's Board of Directors.

        International sales as a percentage of total sales in fiscal 1996, 1997
and 1998 were 42.5%, 42.0% and 39.1%, respectively. Sales to customers in the
U.S. in fiscal 1996, 1997 and 1998 were approximately, $16.0 million, $27.7
million and $26.6 million, respectively, while the Company's sales in Asia for
the same time periods were $8.2



                                      -8-
<PAGE>   9


million, $14.6 million and $15.5 million, respectively, and sales in Europe
were $3.6 million, $5.5 million and $1.6 million, respectively. The Company
receives all payments for all products and services in U.S. dollars.

SERVICE AND SUPPORT

        The Company maintains an international service and support network
responsible for on-site maintenance and process monitoring on either a
contractual or time-and-materials basis. Customers may purchase annual service
contracts under which the Company is required to maintain an inventory of
replacement parts and to service the equipment upon the request of the
customer. The Company also sells replacement parts from inventory for customer
needs. The Company pursues a program of system upgrades for customers to
increase the performance of older systems. The Company generally does not offer
extended payment terms to its customers and generally adheres to a warranty
policy of up to one year. Consistent with industry practice, the Company
maintains an inventory of components for servicing systems in the field and it
believes that its inventory is sufficient to satisfy foreseeable short-term
customer requirements.

RESEARCH AND DEVELOPMENT

        To maintain and improve its competitive position, the Company's
research and development efforts are focused on designing new proprietary
products, improving the performance of existing systems, wafers and
package-ready devices and reducing costs in the product manufacturing process.
The Company has dedicated 16 EMCORE TurboDiscTM systems for both research and
production which are capable of processing virtually all compound semiconductor
materials. The research and development staff utilizes x-ray, optical and
electrical characterization equipment which provide instant data allowing for
shortened development cycles and rapid customer response. The Company's
recurring research and development expenses in fiscal 1996, 1997 and 1998 were
approximately $5.4 million, $9.0 million and $16.5 million, respectively. The
Company also incurred a one-time, non-cash research and development expense in
fiscal 1998 in the amount of $29.3 million in connection with the acquisition
of MODE. The Company expects that it will continue to expend substantial
resources on research and development.

        The Company also competes for research and development funds. In view
of the high cost of development, the Company solicits research contracts that
provide opportunities to enhance its core technology base or promote the
commercialization of targeted products. The Company presently has three such
contracts in process. The contracts fall under the Small Business Innovative
Research programs or similar government sponsored programs. From inception
until September 30, 1998, government and other external research contracts have
provided approximately $13.2 million to support the Company's research and
development efforts. The Company is also positioned to market technology and
process development expertise directly to customers who require it for their
own product development efforts.

INTELLECTUAL PROPERTY AND LICENSING

        The Company's success and competitive position both for production
systems, wafers and package-ready devices depend significantly on its ability
to maintain trade secrets, patents and other intellectual property protections.
Trade secrets are routinely employed in the Company's manufacturing processes.
A "trade secret" is information that has value to the extent it is not
generally known, not readily ascertainable by others through legitimate means,
and protected in a way that maintains its secrecy. In order to protect its
trade secrets, the Company takes certain measures to ensure their secrecy, such
as executing non-disclosure agreements with its employees, customers and
suppliers.

         To date, the Company has been issued eleven U.S. patents and seven are
either pending or under review. These U.S. patents will expire between 2005 and
2013. None of these U.S. patents claim any material aspect of the current or
planned commercial versions of the Company's systems, wafers or devices.

        MODE is a licensee of certain VCSEL technology and associated patent
rights owned by Sandia pursuant to a License Agreement dated September 18, 1997,
between MODE and Sandia (the "Sandia License"). The Sandia License grants MODE
(i) exclusive rights (subject to certain rights granted to Department of Energy
("DOE") and AT&T Corporation ("AT&T")) to develop, manufacture and sell products
containing Sandia VCSEL technologies for barcode scanning and plastic fiber
communications applications under five U.S. patents that expire between 2007 and
2015, and (ii) nonexclusive rights with respect to all other applications of
these patents. The Sandia License also grants MODE a nonexclusive right to
employ a proprietary oxidation fabrication method in the



                                      -9-
<PAGE>   10


manufacture of VCSEL products under a sixth U.S. patent that expires in 2014.
The Company's success and competitive position as a producer of VCSEL products
depends on the continuation of its rights under the Sandia License, the scope
and duration of those rights and the ability of Sandia to protect its
proprietary interests in the underlying technology and patents. MODE's rights
under the Sandia License are subject to termination by Sandia prior to
expiration of the underlying patents in the event that MODE breaches certain
terms specified therein, including failure by MODE to make minimum royalty
payments.

ENVIRONMENTAL REGULATIONS

        The Company is subject to federal, state and local laws and regulations
concerning the use, storage, handling, generation, treatment, emission,
release, discharge and disposal of certain materials used in its research and
development and production operations, as well as laws and regulations
concerning environmental remediation and employee health and safety. The
Company has retained an environmental consultant to advise it in complying with
applicable environmental and health and safety laws and regulations, and
believes that it is currently, and in the past has been, in substantial
compliance with all such laws and regulations.

BACKLOG

        As of September 30, 1998, the Company had an order backlog of
approximately $22.6 million compared to backlog of $24.4 million as of
September 30, 1997. The Company includes in backlog only customer purchase
orders which have been accepted by the Company and for which shipment dates
have been assigned within the twelve months to follow and research contracts
that are in process or awarded. Wafer and device agreements extending longer
than one year in duration are included in backlog only for the ensuing 12
months. Some of these agreements currently extend over three years. The Company
receives partial advance payments or irrevocable letters of credit on most
production system orders. The Company recognizes revenue upon shipment. For
research contracts with the U.S. government and commercial enterprises with
durations greater than six months, the Company recognizes revenue to the extent
of costs incurred plus a portion of estimated gross profit, as stipulated in
such contracts, based on contract performance. Subsequent to year end, the
Company's backlog has increased significantly. As of December 15, 1998, the
Company's order backlog exceeded $41.0 million, an increase of 81.4% since
September 30, 1998.

MANUFACTURING

        In May 1998, the Company received ISO 9001 and QS 9002 quality
certification. The Company's manufacturing operations are located at the
Company's headquarters in Somerset, New Jersey and in Albuquerque, New Mexico
and include systems engineering and production, wafer fabrication, and design
and production of devices. Many of the Company's manufacturing operations are
computer monitored or controlled, therefore enhancing reliability and yield.
The Company manufactures its own systems and outsources some components and
sub-assemblies, but performs all final system integration, assembly and
testing. The Company fabricates wafers and devices at its facilities in
Somerset, New Jersey and Albuquerque, New Mexico and has a combined clean room
area totaling approximately 12,000 square feet.

        Outside contractors and suppliers are used to supply raw materials and
standard components and to assemble portions of end systems from Company
specifications. The Company depends on sole, or a limited number of, suppliers
of components and raw materials. The Company generally purchases these single
or limited source products through standard purchase orders. The Company also
seeks to maintain ongoing communications with its suppliers to guard against
interruptions in supply and has, to date, generally been able to obtain
sufficient supplies in a timely manner and maintains inventories it believes
are sufficient to meet its near term needs. The Company has recently
implemented a vendor program through which it inspects quality and reviews
supplies and prices in order to standardize purchasing efficiencies and design
requirements to maintain as low a cost of sales as possible. However, operating
results could be materially adversely affected by a stoppage or delay of
supply, receipt of defective parts or contaminated materials, and increase in
the pricing of such parts or the Company's inability to obtain reduced pricing
from its suppliers in response to competitive pressures.

COMPETITION

        The markets in which the Company competes are highly competitive. The
Company competes with several companies for sales of MOCVD systems including
Aixtron, Nippon-Sanso and Thomas Swann. The primary



                                     -10-
<PAGE>   11


competitors for the Company's wafer foundry include Epitaxial Products Inc.,
Kopin Corporation and Quantum Epitaxial Designs, Inc. The Company's principal
competitors for sales of VCSEL-related products include Honeywell, Inc. and
Mitel Corporation. The Company also faces competition from manufacturers that
implement in-house systems for their own use. In addition, the Company competes
with many research institutions and universities for research contract funding.
The Company also sells its products to current competitors and companies with
the capability of becoming competitors. As the markets for the Company's
products grow, new competitors are likely to emerge, and present competitors may
increase their market share.

        The Company believes that the primary competitive factors in the
markets in which the Company's products compete are yield, throughput, capital
and direct costs, system performance, size of installed base, breadth of
product line and customer satisfaction, as well as customer commitment to
competing technologies. The Company believes that in order to remain
competitive, it must invest significant financial resources in developing new
product features and enhancements and in maintaining customer satisfaction
worldwide.

EMPLOYEES

        At September 30, 1998, the Company employed 308 full-time employees, up
13.7% from 271 as of September 30, 1997 and up 66.5% from the 185 employees at
September 30, 1996. The increase in the number of employees since the end of
fiscal 1996 is a direct result of the Company's increased manufacturing
operation needs to meet the demand for its compound semiconductor production
systems, wafers and package-ready devices. None of the Company's employees are
covered by a collective bargaining agreement. The Company considers its
relationship with its employees to be good.

ITEM 2. PROPERTIES

        The Company's executive office and manufacturing facility are located
in Somerset, New Jersey, where the Company leases a 75,000 square foot
facility. This facility lease expires on February 2000. The Company has two
five-year renewal options. MODE's office and manufacturing facility are located
in Albuquerque, New Mexico, where MODE leases an aggregate of approximately
27,500 square feet in two adjacent buildings. One of these leases expires in
July 1999 and the other in April 2001, each with two three-year renewal
options. The Company has another office and manufacturing facility in
Albuquerque, New Mexico where it has recently completed building its own 50,000
square foot facility, of which 25,000 square feet is currently occupied.

ITEM 3. LEGAL PROCEEDINGS

        Neither the Company nor its subsidiary is aware of any pending or
threatened litigation against it which would have a material adverse effect on
its business, financial condition and results of operations.

its Common Stock in the foreseeable future so that it may reinvest its earnings
in the development of its business. The payment of dividends, if any, in the
future will be at the discretion of the Board of Directors.

        RECENT SALES OF UNREGISTERED SECURITIES

        On November 30, 1998, the Company sold an aggregate of 1,550,000 shares
of Series I Preferred Stock to Hakuto, UMI and UTC for an aggregate
consideration of $21.7 million before deducting costs and expenses of the
offering of approximately $500,000. The shares of Series I Preferred Stock are
convertible, at any time, at the option of the holders thereof, unless
previously redeemed, into shares of Common Stock at an initial conversion price
of $14.00 per share of Common Stock, subject to adjustment in certain cases.
The Series I Preferred Stock is redeemable, in whole or in part, at the option
of the Company at any time the Company's stock has traded at or above $28.00
per share for 30 consecutive trading days, at a price of $14.00 per share, plus
accrued and unpaid dividends, if any, to the redemption date. In addition, the
Series I Preferred Stock is subject to mandatory redemption by the Company on
November 17, 2003. The Company believes the sale of the shares of Series I
Preferred Stock is exempt from registration pursuant to Section 4(2) of the
Securities Act of 1933, as amended (the "Securities Act").

        On June 22, 1998 the Company issued 227,747 warrants to purchase common
stock of the Company to Thomas Russell, Chairman of the Board of Directors of
the Company and 56,937 warrants to purchase common stock of the Company to
Reuben Richards, President, Chief Executive Officer and a director of the
Company. The warrants are exercisable at a price of $11.375 and expire on May
1, 2001. These warrants are callable at the Company's option at $.85 per
warrant at such time as the Company's Common Stock has traded at or above 150%
of the exercise price for a period of 30 days. These warrants were granted in
exchange for the guarantee by these executives of the 1998 Agreement entered
into by the Company on June 22, 1998 with the Bank. The credit facility is
being used to finance general corporate purposes, including, but not limited
to, the construction of a facility in Albuquerque, New Mexico. The term of the
credit facility is 18 months and the interest rate is at LIBOR plus 0.75%. The
Company received a fairness opinion from its investment bank, Hempstead &
Company, that this transaction was fair from a financial point of view to the
Company's non-participating shareholders. The Company believes the issuance of
the warrants is exempt from registration pursuant to Section 4(2) of the
Securities Act.

        On December 5, 1997, the Company issued 1,461,866 shares of Common
Stock, 200,966 common stock purchase options and 47,118 common stock purchase
warrants in exchange for all of the outstanding capital stock of MODE. The
purchase price was approximately $32.8 million and was recorded under the
purchase method of accounting. The Company believes the issuance of Common
Stock, options and warrants in connection with the acquisition of MODE is
exempt from registration pursuant to Section 4(2) of the Securities Act.

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

OVERVIEW

        The compound semiconductor industry is experiencing dramatic growth with
increasing demands for higher performance and functionality in applications for
products as diverse as electronic displays, advanced automotive and aircraft
engines, wireless communications, telecommunications, CDs, DVDs, CATV, fiber
optic transmitters, bar code scanners, satellites, cellular phones, laser
printers, and holographic memories.

        EMCORE, founded in 1984, designs and develops compound semiconductor
materials and process technology and is a leading manufacturer of production
systems used to fabricate compound semiconductor wafers. The Company provides
its customers, both in the U.S. and internationally, with materials science
expertise, process technology and compound semiconductor production systems that
enable the manufacture of commercial volumes of high-performance electronic and
optoelectronic devices. In response to the growing need of its customers to cost
effectively get to market faster with higher volumes of new and improved high
performance products, the Company expanded its product offerings to include the
design, development and production of compound semiconductor wafers,
package-ready devices and discreet components and now offers its customers a
broad range of products and services and a vertically integrated product line.
EMCORE believes that its proprietary TurboDisc(TM) deposition technology makes
possible one of the most cost-effective production systems for the commercial
volume manufacture of high-performance compound semiconductor wafers and
devices. The Company is a leading manufacturer of MOCVD systems, the enabling
technology behind compound semiconductor products and the resulting dramatic
improvements in speed, capacity and functionality. MOCVD is the means by which
chemicals are deposited in atomic layers on a substrate, and many compound
semiconductor products are produced on MOCVD equipment. The Company's MOCVD
technology and fifteen years of material science knowledge and know how,
position the Company to capitalize on market opportunities.

        To this extent, the Company has concentrated on several products serving
large opto-electronics markets: HB LEDs, high efficiency solar cells, VCSELs,
antimonide MR Sensors and epitaxial services. All of these products are based on
the Company's TurboDisc(TM) production system, the enabling technology.

        The Company's two product lines, systems and materials, differ
significantly. Systems-related revenues include sales of Turbo-disc(TM) systems
as well as spare parts and services. The book to ship time period on systems is
approximately four to six months, while the average selling price is in excess
of $1.0 million. Materials revenues include wafers, devices and process
development technology. The materials sales cycle is generally shorter than
systems and average selling prices vary significantly based on the products.
Generally, the Company achieves a higher gross profit on its materials related
products.

        In conjunction with the vertical expansion of the Company's product
lines, EMCORE began fiscal 1998 with a capital plan requiring $35.0 million.
These funds were required to build the Company's manufacturing and development
infrastructure and to take advantage of market windows for new products which
the Company had under development. The Company believes it now has the majority
of the infrastructure required to address the needs of the compound
semiconductor industry.

        To expand its technology base into the data communications and
telecommunications markets, on December 5, 1997, the Company purchased MODE for
a purchase price of $32.8 million. EMCORE's acquisition of MODE (a development
stage company), constituted a significant and strategic investment for the
Company to acquire and gain access to MODE's in-process research and development
of micro-optical technology. The Company's over-riding investment consideration
was that if MODE's research and development efforts (with continued research and
development funding contemplated and acquired after acquisition) yielded
commercial products for targeted applications EMCORE would possess a broader
array of enabling technologies and would be better positioned for entry into
certain existing large and/or high growth technology dependent markets. MODE is
one of the market leaders in the design and development of high-quality optical
components and subassemblies which offer superior performance at lower cost over
conventional semiconductor laser technologies. MODE's microlasers and optical
subassemblies are expected to provide design, performance and significant cost
advantages over their technical predecessors such as edge-emitting solid state
lasers. Through the integration of VCSELs with leading OEM systems design,
VCSELs are expected to provide enhanced performance benefits to market
applications such as Internet access, onboard photonics, gigabit ethernet, local
area networks, microarea network, DVD and fiberoptic switching. On February 23,
1998, MODE announced the introduction of its first commercial product, a
Gigalase VCSEL. Subsequent to such announcement, MODE's Gigalase product efforts
were primarily directed toward engineering, testing and quality control
activities to facilitate commercial production which commenced in May 1998. On
December 14, 1998, MODE announced its second commercial product a Gigarray
VCSEL.



                                     -14-
<PAGE>   15


        As part of the acquisition, the Company incurred a one-time in-process
research and development write-off of $29.3 million which is reflected in the
accompanying financial statements. The Company also recorded goodwill of
approximately $3.4 million. This is being charged against operations over a
three year period, and will therefore, impact financial performance through
December 2000.

        In addition to the MODE acquisition, the Company launched three joint
ventures during the past year. In July 1998, the Company formed and is a
minority investor in Uniroyal Optoelectronics, LLC a joint venture with UTC to
manufacture, sell and distribute HB LEDs. In November 1998, the Company formed a
joint venture with Optek Technology, Inc., a packager and distributor of
optoelectronic devices including sensors, to market an expanded line of MR
Sensors to the automotive and related industries. Combining the Company's
strength in producing the package-ready die along with Optek's strength in
packaging and distribution allows the Company to alter the shelf products which
should allow for greater market penetration. Also in November 1998, the Company
and Union Miniere Inc. formed UMCORE to explore and develop alternate uses of
germanium using the Company's material science and production platform
expertise.

        In November 1998, the Company signed the Long Term Purchase Agreement
with Loral, a wholly owned subsidiary of Loral Space & Communications. The Long
Term Purchase Agreement, once EMCORE completes Loral's space qualification and
test procedures, enlists EMCORE as a supplier of compound semiconductor high
efficiency gallium arsenide solar cells for Loral's satellite requirements.
Subject to the foregoing requirements, the Company received an initial purchase
order for $5.25 million of solar cells.

        In September 1998, the Company entered into an agreement with LMMS for
the technical management and support of a LMMS and Sandia CRADA for the
advancement, transfer and commercialization of a new compound semiconductor high
efficiency solar cell. The Company also signed a four year purchase agreement
with AMP Incorporated to provide high speed VCSELs. AMP Incorporated presently
uses the Company's VCSELs in transceivers for Gigabit Ethernet applications.

        The Company believes it possesses the technological "know how" to
capitalize on all of these market opportunities. However, there can be no
assurance that the Company will maintain sufficient growth in sales levels to
support the associated labor, equipment and facility costs.

RESULTS OF OPERATIONS:

        The following table sets forth the Statement of Income Data of the
Company expressed as a percentage of total revenues for the fiscal years ended

</TABLE>


COMPARISON OF FISCAL YEARS ENDED SEPTEMBER 30, 1997 AND 1998

REVENUES

        The Company's revenues decreased 8.4% from $47.8 million for the fiscal
year ended September 30, 1997 to $43.8 million for the fiscal year ended
September 30, 1998. The revenue decrease represented a shift in product mix
during the year. Equipment related revenues decreased approximately 22.3% while
materials related revenues increased approximately 26.5%. The decrease in
equipment revenues was primarily attributable to the financial issues in the
Asian economies as well as a general slowdown in the semiconductor equipment
market overall. While materials related revenues did experience a 26.5%
increase, the General Motors three month strike adversely affected



                                     -15-
<PAGE>   16


revenue, as shipments to General Motors were halted during the strike.
International sales accounted for approximately 42.0% and 39.1% of revenues for
the fiscal years ended September 30, 1997 and 1998, respectively.

        The Company believes that in the future its revenues and results of
operations in a given quarterly period could be impacted by the timing of
customer development projects and related purchase orders for the Company's
varied products, new merchandise announcements and releases by the Company, and
conditions in the economy, generally and in the compound semiconductor industry
environment, specifically.

COST OF SALES/GROSS PROFIT

        Cost of sales includes direct material and labor costs, allocated
manufacturing and service overhead, and installation and warranty costs. Gross
profit increased from 37.0% of revenue to 43.6% of revenue for the fiscal years
ended September 30, 1997 and 1998, respectively. The gross profit percentage
increase was attributable to a shift in product mix towards higher gross margin
materials related revenues.

SELLING, GENERAL AND ADMINISTRATIVE

        Selling, general and administrative expenses increased by 50.7% from
$9.3 million for the year ended September 30, 1997, to $14.1 million for the
year ended September 30, 1998. The increase was largely due to sales personnel
headcount increases to support both domestic and foreign markets and general
headcount additions to sustain the internal administrative support necessary for
the Company's expanded product lines and new locations. During fiscal 1998, the
Company wrote-off a $1.0 million receivable due from an Asian customer which was
deemed to be uncollectible. As a percentage of revenue, selling, general and
administrative expenses increased from 19.6% of revenue during fiscal 1997 to
32.2% of revenue for fiscal 1998. The Company believes that selling, general
and administrative expenses will decrease as a percentage of revenues in fiscal
1999.

GOODWILL AMORTIZATION

        In connection with the purchase of MODE, the Company recorded goodwill
of $3.4 million which is being amortized this amount over 36 months. Goodwill
amortization expense amounted to $922,000 for the year ended September 30, 1998.
Net goodwill at September 30, 1998 was $2,457,000.

RESEARCH AND DEVELOPMENT

        Recurring research and development expenses increased by 83.3% from
$9.0 million for the year ended September 30, 1997, to $16.5 million for the
year ended September 30, 1998. The increase was primarily attributable to the
Company's acquisition of MODE and increased staffing and equipment costs
necessary to enhance current products and develop new product offerings.
Products introduced or under development include HB LEDs, high efficiency solar
cells, new generation TurboDisc(TM) production systems, VCSELs and other
optoelectronic devices. As a percentage of revenue, research and development
expenses increased from 18.9% of revenue during fiscal 1997 to 37.7% of revenue
for fiscal 1998. To maintain growth and market leadership in epitaxial
technology, the Company expects to continue to invest a significant amount of
its resources in research and development.

        In connection with the MODE acquisition, the Company incurred a
one-time charge for the write-off of acquired in-process research and
development amounting to $29.3 million.

OPERATING LOSS

        During fiscal 1998, operating loss increased from a loss of $0.7 million
for the fiscal year ended September 30, 1997, to a loss of $41.7 million for the
year ended September 30, 1998. The change in operating loss was primarily due to
the $29.3 million one-time charge for in-process research and development
written off in connection with the purchase of MODE. In addition, the General
Motors three month strike adversely affected operating performance as shipments
to General Motors were halted during the strike. General Motors is among the
Company's largest customers. The Company was unable to furlough or reduce their
workforce during the strike and thereby incurred charges without the benefit of
related revenues.



                                     -16-
<PAGE>   17


OTHER EXPENSE

        Other expenses decreased, particularly due to the reduced imputed
warrant interest expense associated with the Company's subordinated debt and
debt issuance guarantee cost. During fiscal 1996, the Company issued detachable
warrants along with subordinated notes to certain of its existing shareholders.
In fiscal year 1997, the Company also issued detachable warrants in return for
a $10.0 million demand note facility (the "Facility") guarantee by the Chairman
of the Board of the Company, who provided collateral for the Facility. The
Company subsequently assigned a value to these detachable warrants issued using
the Black-Scholes Option Pricing Model. The Company recorded the subordinated
notes at a carrying value that is subject to periodic accretions, using the
interest method, and reflected the Facility's detachable warrant value as debt
issuance cost which was written off in its entirety in fiscal 1997. The
consequent expense of these subordinated note accretion amounts and the now
terminated Facility's debt issuance cost is charged to "imputed warrant
interest, non-cash," and amounted to approximately $4.0 million and $600,000
for the fiscal years ended September 30, 1997 and 1998, respectively. In June
1998, the Company issued 284,684 warrants to its Chairman and its Chief
Executive Officer for providing a guarantee in connection with the 1998
Agreement, an $8.0 million 18 month credit facility with the Bank. The Company
assigned a value to these detachable warrants issued using the Black-Scholes
Option Pricing Model. As a result, the Company will record imputed warrant
interest, non-cash of approximately $1.3 million over the life of the credit
facility.

INCOME TAXES

        The Company's effective income tax rate was 0.0% in fiscal 1998, 2.6% in
fiscal 1997 and 0.0% in fiscal 1996. The lower effective rate in fiscal 1998 and
1996, relative to fiscal 1997, was attributable to a federal income tax benefit
offset by net operating loss and expenses not utilized or deductible for tax
purposes.

        As of September 30, 1998, the Company has net operating loss
carryforwards for regular tax purposes of approximately $22.0 million which
expire in the years 2003 through 2012. The Company believes that the
consummation of certain equity transactions and a significant change in the
ownership during fiscal year 1995 has constituted a change in control under
Section 382 of the Internal Revenue Code ("IRC"). Due to the change in control,
the Company's ability to use its federal net operating loss carryovers and
federal research credit carryovers to offset future income and income taxes,
respectively, are subject to annual limitations under IRC Section 382 and 383.

        The Company believes that the acquisition of MODE and the consummation
of certain other equity transactions has constituted a change in control in
fiscal 1998 under Section 382 of the IRC. As such, Federal net operating loss
carryovers and research credit carryovers incurred subsequent to the Company's
fiscal 1995 change in control (as described above) will also be subject to
annual limitations under IRC Section 382 and 383.

EXTRAORDINARY ITEM

        In the fiscal year ended September 30, 1997, the Company repaid $2.0
million of its outstanding subordinated notes due May 1, 2001. In connection
with this discharge of the Company's subordinated notes, an extraordinary loss
of $286,000 was recognized in fiscal 1997 relating to such early extinguishment
of debt.

NET LOSS

        Net loss increased $5.6 million for the fiscal year ended September 30,
1997, to $43.5 million for the fiscal year ended September 30, 1998. This
increase was primarily attributable to the aforementioned acquisition of MODE
and subsequent write-off of in-process research and development of $29.3
million. In addition, the General Motors three month prolonged strike adversely
affected operating performance.

COMPARISON OF FISCAL YEARS ENDED SEPTEMBER 30, 1996 AND 1997

REVENUES

        The Company's revenues for fiscal 1997 increased 71.9% from $27.8
million to $47.8 million for the fiscal year ended September 30, 1996. The
revenue increase was primarily attributable to increased demand of MOCVD
systems and package-ready devices, as well as the introduction of compound
semiconductor wafer products.

International sales accounted for approximately 42.5% and 42.0% of revenues for
the fiscal years ended September 30, 1996 and 1997, respectively.

COST OF SALES/GROSS PROFIT

        Cost of sales includes direct material and labor costs, allocated
manufacturing and service overhead, and installation and warranty costs. Gross
profit increased from 33.0% of revenue to 37.0% of revenue for the fiscal years
ended September 30, 1996 and 1997, respectively. The gross profit percentage
increase was attributable to higher margins on wafer, device and licensing
revenues.

SELLING, GENERAL AND ADMINISTRATIVE

        Selling, general and administrative expenses increased by 43.3% from
$6.5 million for the year ended September 30, 1996, to $9.3 million for the
year ended September 30, 1997. The increase was largely due to sales personnel
headcount increases to support both domestic and foreign markets and general
headcount additions to sustain the internal administrative support necessary
for the Company's increased business as well as higher expenses attributable to
increased revenues. As a percentage of revenue, selling, general and
administrative expenses decreased from 23.5% of revenue during fiscal 1996 to
19.6% of revenue for fiscal 1997.

RESEARCH AND DEVELOPMENT

        Research and development expenses increased by 66.6% from $5.4 million
for the year ended September 30, 1996, to $9.0 million for the year ended
September 30, 1997. The increase was primarily attributable to increased
staffing and equipment costs necessary to enhance current products and research
and development activities for the emulation of the Company's two new product
lines (epitaxial wafers and package-ready devices). As a percentage of revenue,
research and development expenses decreased from 19.4% of revenue during fiscal
1996 to 18.8% of revenue for fiscal 1997. To maintain growth and market
leadership in epitaxial technology, the Company expects to continue to invest a
significant amount of its resources in research and development.

OPERATING LOSS

        During fiscal 1997, operating loss decreased $2.1 million from a loss
of $2.8 million for the fiscal year ended September 30, 1996, to a loss of $0.7
million for the year ended September 30, 1997. The change in operating loss was
primarily due to higher revenues generating greater overall gross profit.

OTHER EXPENSE

        During fiscal 1996, the Company issued detachable warrants along with
subordinated notes to certain of its existing shareholders. In the first
quarter of fiscal year 1997, the Company also issued detachable warrants in
return for the $10.0 million Facility guarantee by the Chairman of the Board of
the Company, who provided collateral for the Facility. The Company subsequently
assigned a value to these detachable warrants issued using the Black-Scholes
Option Pricing Model. The Company recorded the subordinated notes at a carrying
value that is subject to periodic accretions, using the interest method, and
reflected the Facility's detachable warrant value as debt issuance cost. The
consequent expense of these subordinated note accretion amounts and the now
terminated Facility's debt issuance cost is charged to "Imputed warrant
interest, non-cash," related to the warrant issuances in connection with the
$10.0 million Facility, and amounted to approximately $126,000 and $4.0 million
for the fiscal years ended September 30, 1996 and 1997, respectively.

        Borrowings totaling $8.0 million under the Facility were utilized to
fund capital expenditures in connection with the build-out of the Company's
manufacturing facility during the six months ended March 31, 1997. The
resultant interest expense was the primary reason for the increase in "Stated
interest expense" for the year ended September 30, 1997. The outstanding $8.0
million under this demand note facility was repaid in March 1997.

EXTRAORDINARY ITEM

        The Company repaid $10.0 million of its outstanding debt with proceeds
from its initial public offering ("IPO"). The entire $8.0 million outstanding
of its Facility was repaid and $2.0 million was used to repay a portion of



                                     -18-
<PAGE>   19


the Company's outstanding subordinated notes due May 1, 2001. In connection with
this discharge of the Company's subordinated notes, an extraordinary loss of
$286,000 was recognized in fiscal 1997 relating to such early extinguishment of
debt.

NET LOSS

        Net loss increased $2.4 million from $3.2 million for the fiscal year
ended September 30, 1996, to $5.6 million for the fiscal year ended September
30, 1997. This increase was primarily attributable to the aforementioned $4.0
million of non-cash imputed warrant interest associated with certain financing
transactions.

OTHER SELECTED SEPTEMBER 30, 1998 INFORMATION

BACKLOG

        The Company's order backlog decreased 7.4% from $24.4 million for the
fiscal year ended September 30, 1997, to $22.6 million for the fiscal year
ended September 30, 1998. The Company includes in backlog only customer
purchase orders which have been accepted by the Company and for which shipment
dates have been assigned within the twelve months to follow and research
contracts that are in process or awarded. Wafer and device contract agreements
extending longer than one year in duration are included in backlog only for the
ensuing 12 months. Some of these agreements currently extend over three years.
The Company receives partial advance payments or irrevocable letters of credit
on most production system orders. Subsequent to year end, the Company's backlog
has increased significantly. As of December 15, 1998, the Company's order
backlog exceeded $41.0 million, an increase of 81.4% since September 30, 1998.

LIQUIDITY AND CAPITAL RESOURCES

        Cash and cash equivalents increased by approximately $800,000 from $3.7
million at September 30, 1997, to $4.5 million at September 30, 1998. For the
year ended September 30, 1998, net cash used by operations amounted to $1.6
million, primarily due to the Company's net losses excluding the acquired
in-process research and development non-cash charge and increase in inventories
which was partially offset by the Company's non-cash depreciation and
amortization charges, its increase in accounts payable and advanced billings,
and its decrease in accounts receivable.

        For the year ended September 30, 1998, net cash used in investment
activities amounted to $22.2 million primarily due to the purchase and
manufacture of new equipment for the Company's wafer and package ready device
product lines and clean room modifications and enhancements, as well as its
purchase of land and construction of a facility in Albuquerque, New Mexico to
be used for the manufacture of wafers and package ready devices.

        On March 31, 1997, the Company entered into the 1997 Agreement, a $10.0
million revolving loan which bears interest at the rate of prime plus 50 basis
points (8.0% at September 30, 1998). As a result of the net loss for the quarter
ended June 30, 1998, the Company was not in compliance with the 1997 Agreement
fixed charge coverage ratio covenant. The Company received a waiver from the
bank regarding this non-compliance. The Company and the Bank amended the 1997
Agreement as of November 30, 1998 to, among other things, extend the expiration
until October 1, 1999 and modify certain financial covenants. In addition,
pursuant to the amendment of the 1997 Agreement, Thomas Russell, the Chairman of
the Board of the Company will guarantee the debt in the event that the Company
does not meet certain financial covenants. On June 22, 1998, the Company entered
into the 1998 Agreement, an $8.0 million loan agreement with the Bank, which
expires December 31, 1999. The 1998 Agreement bears interest at a rate equal to
one-month LIBOR plus three-quarters of one percent per annum (6.4% at September
30, 1998). As of September 30, 1998, the Company had borrowed approximately
$10.0 million under the 1997 Agreement and $8.0 million under the 1998
Agreement.

        On September 17, 1998, the Company borrowed $7.0 million from its
Chairman, Thomas J. Russell. The loan bears interest at 9.75% per annum. In
addition, on October 23, 1998 the Company borrowed an additional $1.5 million
from its Chairman on identical terms. The entire $8.5 million, borrowed from
Thomas J. Russell was repaid from the proceeds of the Private Placement. The
Company received a waiver from the Bank regarding the repayment of this debt.



                                     -19-
<PAGE>   20


        Net cash provided by financing activities for the year ended September
30, 1998 amounted to approximately $24.6 million, primarily due to the
Company's proceeds of approximately $18.0 million from borrowings under the
1997 and 1998 Agreements and the $7.0 million note to the Company's Chairman.

        The Company's operations are subject to a number of risks, including but
not limited to a history of net losses from operations, future capital needs,
dependence on key personnel, competition and risk of technological obsolescence,
governmental regulations and approvals, research and development results,
continued development of its compound semiconductor manufacturing and marketing
capabilities and a concentration of international sales in Asia. The Company's
operations for the year ended September 30, 1998, were primarily funded through
borrowings under existing credit facilities and short-term advances from the
Company's Chairman - aggregating $7.0 million as of September 30, 1998. The
Company's Chairman has from time to time provided credit enhancements in the
form of debt guarantees and has loaned the Company funds to support its
expansion and capital equipment requirements. The Company's Chief Executive
Officer has also provided credit enhancements in the form of debt guarantees for
the Company. Subsequent to September 30, 1998, the Company completed the Private
Placement, resulting in proceeds of $21.2 million. The Company repaid its
Chairman $8.5 million (including $1.5 million advanced to the Company subsequent
to September 30, 1998), invested approximately $5.6 million in two
unconsolidated ventures and the balance of approximately $7.0 million will be
used for general working capital purposes. In addition, the Company's $10.0
million credit facility was extended to October 1, 1999. The Company's operating
plans include, among other things attempting to improve (i) operating cash flow
through increased sales of compound semiconductor systems, wafers and
package-ready devices and (ii) managing its cost structure in relation to its
anticipated level of revenues. The Company believes that its current liquidity,
together with available credit facilities and the proceeds from the Private
Placement, should be sufficient to meet its cash needs for working capital
through fiscal 1999. However, if the proceeds from the Private Placement, cash
generated from operations and cash on hand are not sufficient to satisfy the
Company's liquidity requirements, the Company will seek to obtain additional
equity or debt financing. Additional funding may not be available when needed or
on terms acceptable to the Company. If the Company is required to raise
additional financing and if adequate funds are not available or are not
available on acceptable terms, the ability to continue to fund expansion,
develop and enhance products and services, or otherwise respond to competitive
pressures would be severely limited. Such a limitation could have a material
adverse effect on the Company's business, financial condition or operations.

YEAR 2000 COMPLIANCE

         Many currently installed computer systems and software products are
coded to accept or recognize only two digit entries in the date code field.
These systems and software products will need to accept four digit entries to
distinguish 21st century dates from 20th century dates. As a result, computer
systems and/or software used by many companies and governmental agencies may
need to be upgraded to comply with such Year 2000 requirements or risk system
failure or miscalculations causing disruptions of normal business activities.

        STATE OF READINESS

         The Company has made a preliminary assessment of the Year 2000
readiness of its operating financial and administrative systems, including the
hardware and software that support such systems. The Company's assessment plan
consists of (i) quality assurance testing of its internally developed
proprietary software; (ii) contacting third-party vendors and licensors of
material hardware, software and services that are both directly and indirectly
related to the Company's business; (iii) contacting vendors of third-party
systems; (iv) assessing repair or replacement requirements; (v) implementing
repair or replacement; and (vi) creating contingency plans in the event of Year
2000 failures. The Company plans to perform a Year 2000 simulation on its
systems during the second quarter of 1999 to test system readiness. Many
vendors of material hardware and software components of its systems have
indicated that the products used by the Company are currently Year 2000
compliant. The Company will require vendors of its other material hardware and
software components of its systems to provide assurances of their Year 2000
compliance. The Company plans to complete this process during the first half of
1999. Until such testing is completed and such vendors and providers are
contacted, the Company will not be able to completely evaluate whether its
systems will need to be revised or replaced.



                                     -20-
<PAGE>   21


        COSTS

         To date, the Company has not incurred any material expenditures in
connection with identifying, evaluating or addressing Year 2000 compliance
issues. Most of the Company expenses have related to, and are expected to
continue to relate to, the operating costs associated with time spent by
employees in the evaluation process and Year 2000 compliance matters generally.
At this time, the Company does not possess the information necessary to
estimate the potential costs of revisions to its systems should such revisions
be required or the replacement of third-party software, hardware or services
that are determined not to be Year 2000 compliant. Although the Company does
not anticipate that such expenses will be material, such expenses if higher
than anticipated could have a material adverse effect on the Company's
business, results of operations and financial condition.

        RISKS

         The Company is not currently aware of any Year 2000 compliance
problems relating to its systems that would have a material adverse effect on
the Company business, results of operations and financial condition, without
taking into account the Company efforts to avoid or fix such problems. There
can be no assurance that the Company will not discover Year 2000 compliance
problems in its systems that will require substantial revision. In addition,
there can be no assurance that third-party software, hardware or services
incorporated into the Company material systems will not need to be revised or
replaced, all of which could be time-consuming and expensive. The failure of
the Company to fix or replace its internally developed proprietary software or
third-party software, hardware or services on a timely basis could result in
lost revenues, increased operating costs, the loss of customers and other
business interruptions, any of which could have a material adverse effect on
the Company business, result of operations and financial condition. Moreover,
the failure to adequately address Year 2000 compliance issues in its internally
developed proprietary software could result in claims of mismanagement,
misrepresentation or breach of contract and related litigation, which could be
costly and time-consuming to defend.

         In addition, there can be no assurance that governmental agencies,
utility companies, third-party service providers and others outside of the
Company's control will be Year 2000 compliant. The failure by such entities to
be Year 2000 compliant could result in systemic failure beyond the control of
the Company's such as a telecommunications or electrical failure, which could
have a material adverse effect on the Company's business, results of operations
and financial condition.

        CONTINGENCY PLAN

         As discussed above, the Company is engaged in an ongoing Year 2000
assessment and has not yet developed any contingency plans. The results of the
Company's Year 2000 simulation testing and the responses received from
third-party vendors and service providers will be taken into account in
determining the nature and extent of any contingency plans.

RECENT ACCOUNTING PRONOUNCEMENTS

         In June 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 131, "Disclosures
about Segments of an Enterprise and Related Information" ("SFAS No. 131"),
which establishes standards for reporting information about operating segments
in annual financial statements. It also establishes standards for related
disclosures about products and services, geographic areas and major customers.
SFAS No. 131 is effective for fiscal years beginning after December 15, 1997.
The Company will be required to adopt this standard in its fiscal year ending
September 30, 1999. The adoption of SFAS No. 131 is not expected to have an
impact on the Company's results of operations, financial position or cash
flows.

         In February 1998, FASB issued SFAS No. 132, "Employers' Disclosures
about Pension and Other Postretirement Benefits" ("SFAS No. 132"), which
requires disclosure about pension and postretirement benefits. SFAS No. 132
does not change the measurement or recognition of these plans. SFAS No. 132 is
effective for fiscal years beginning after December 15, 1997. The adoption of
SFAS No. 132 is not expected to have an impact on the Company's results of
operations, financial position or cash flows.

         In March 1998, the American Institute of Certified Public Accountants
("AICPA") issued Statement of Position ("SOP") 98-1, "Accounting for the Cost
of Computer Software Developed or Obtained for Internal Use"



                                     -21-
<PAGE>   22


("SOP 98-1"). SOP 98-1 is effective for financial statements for years
beginning after December 14, 1998. SOP 98-1 provides guidance over accounting
for computer software development or obtained for internal use including the
requirement to capitalize specified costs and amortization of such costs. The
Company does not expect the adoption of this standard to have a material effect
results of operations, financial position or cash flows.

         In April 1998, the AICPA issued Statement of Position 98-5, "Reporting
on the Costs of Start-Up Activities" ("SOP 98-5"). SOP 98-5, which is effective
for fiscal years beginning after December 15, 1998, provides guidance on the
financial reporting of start-up costs and organization costs. It requires costs
of start-up activities and organization costs to be expensed as incurred. As
the Company has expensed these costs historically, the adoption of this
standard is not expected to have a significant impact on the Company's results
of operations, financial position or cash flows.

ITEM 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

        During fiscal 1998, the Company was not a party to any derivative
contracts, hedging or other market risk transactions.

                               EMCORE Corporation

                         Notes to Financial Statements

NOTE 1.  DESCRIPTION OF BUSINESS

        EMCORE is a designer and developer of compound semiconductor materials
and process technology and a manufacturer of production systems used to
fabricate compound semiconductor wafers. Compound semiconductors are used in a
broad range of applications in wireless communications, telecommunications,
computers, and consumer and automotive electronics. The Company has recently
capitalized on its technology base by expanding into the design and production
of compound semiconductor wafers and package-ready devices and under specific
arrangements has licensed certain process technologies. During fiscal 1998, the
Company completed the acquisition of a development stage company focused on the
research and development of optical laser technologies (see Note 3). The
Company offers its customers a complete, vertically-integrated solution for the
design, development and production of compound semiconductor wafers and
devices.

        BASIS OF PRESENTATION AND LIQUIDITY. The accompanying financial
statements have been prepared on a going concern basis. The Company for the year
ended September 30, 1998, experienced a 10% decline in revenue of approximately
$4.0 million and a substantial operating loss amounting to approximately $41.7
million (approximately $12.5 million excluding the effect of acquired in-process
research and development) and had a working capital deficiency of $2.0 million.

        The Company's operations are subject to a number of risks, including but
not limited to a history of net losses from operations, future capital needs,
dependence on key personnel, competition and risk of technological obsolescence,
governmental regulations and approvals, research and development results,
continued development of its compound semiconductor manufacturing and marketing
capabilities and a concentration of international sales in Asia. The Company's
operations for the year ended September 30, 1998, were primarily funded through
borrowings under existing credit facilities, as well as short-term advances from
the Company's Chairman - aggregating $7.0 million as of September 30, 1998. The
Company's Chairman has from time to time provided credit enhancements in the
form of debt guarantees and has loaned the Company funds to support its
expansion and capital equipment requirements. The Company's Chief Executive
Officer has also provided credit enhancements in the form of debt guarantees for
the Company. Subsequent to September 30, 1998, the Company completed a preferred
stock private placement (the "Private Placement," see Note 17), resulting in
proceeds of $21.2 million. The Company repaid its Chairman $8.5 million
(including $1.5 million advanced to the Company subsequent to September 30,
1998), invested approximately $5.6 million in two unconsolidated ventures and
the balance of approximately $7.0 million will be used for general working
capital purposes. In addition, the Company's $10.0 million credit facility was
extended to October 1, 1999. The Company's operating plans include, among other
things attempting to improve (i) operating cash flow through increased sales of
compound semiconductor systems, wafers and package-ready devices and (ii)
managing its cost structure in relation to its anticipated level of revenues.
The Company believes that its current liquidity, together with available credit
facilities and the proceeds from the Private Placement, should be sufficient to
meet its cash needs for working capital through fiscal 1999. However, if the
proceeds from the Private Placement, cash generated from operations and cash on
hand are not sufficient to satisfy the Company's liquidity requirements, the
Company will seek to obtain additional equity or debt financing. Additional
funding may not be available when needed or on terms acceptable to the Company.
If the Company is required to raise additional financing and if adequate funds
are not available or are not available on acceptable terms, the ability to
continue to fund expansion, develop and enhance products and services, or
otherwise respond to competitive pressures would be severely limited. Such a
limitation could have a material adverse effect on the Company's business,
financial condition or operations and the financial statements do not include
any adjustment that could result therefrom.

NOTE 2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

        PRINCIPLES OF CONSOLIDATION. The consolidated financial statements
include the accounts of the Company and its wholly-owned subsidiary. The equity
method of accounting is used for unconsolidated affiliates in which the
Company's equity is at least 20% and not more than 50%. All significant
intercompany transactions are eliminated upon consolidation.



                                     -27-

        CASH AND CASH EQUIVALENTS. The Company considers all highly liquid
short-term investments purchased with an original maturity of three months or
less to be cash equivalents. The Company had approximately $2,254,000 and
$3,003,000 in cash equivalents at September 30, 1997 and 1998, respectively. As
of September 30, 1998, the Company had restricted cash in the amount of $62,500
due to a contractual obligation.

         INVENTORIES. Inventories are stated at the lower of FIFO (first-in,
first-out) cost or market. Reserves are established for slow moving or obsolete
inventory based upon historical and anticipated usage.

        PROPERTY AND EQUIPMENT. Property and equipment are stated at cost.
Significant renewals and betterments are capitalized. Maintenance and repairs
which do not extend the useful lives of the respective assets are expensed.
Depreciation is recorded using the straight-line method over the estimated
useful lives of the applicable assets, which range from three to five years.
Leasehold improvements are amortized using the straight-line method over the
term of the related leases or the estimated useful lives of the improvements,
whichever is less. Depreciation expense includes the amortization of capital
lease assets. When assets are retired or otherwise disposed of, the assets and
related accumulated depreciation accounts are adjusted accordingly, and any
resulting gain or loss is recorded in current operations.

        LONG-LIVED ASSETS. The carrying amount of assets is reviewed on a
regular basis for the existence of facts or circumstances, both internally and
externally, that suggest impairment. To date no such impairment has been
indicated. The Company determines if the carrying amount of a long-lived asset
is impaired based on anticipated undiscounted cash flows before interest. In
the event of an impairment, a loss is recognized based on the amount by which
the carrying amount exceeds fair value of the asset. Fair value is determined
primarily using the anticipated cash flows before interest, discounted at a
rate commensurate with the risk involved.

        DEFERRED COSTS. Included in other assets are deferred costs related to
obtaining product patents and debt issuance costs and an investment in an
unconsolidated affiliate. Amortization expense related to product patents
amounted to approximately $128,000, $40,000 and $79,000 for the years ended
September 30, 1996, 1997 and 1998, respectively. During the year ended September
30, 1998, the Company issued 284,684 common stock purchase warrants in exchange
for the guaranteeing of a credit facility by the Company's Chairman and Chief
Executive Officer. The warrants were assigned a value of $1,310,000 which is
being amortized over the eighteen month term of the facility. The warrants were
valued by the Company based upon its application of the Black Scholes Option
Pricing Model. Amortization expense related to such warrant issuance amounted to
approximately $219,000 for fiscal 1998.

        GOODWILL. Goodwill is amortized using the straight-line method over
three years. The Company evaluates annually whether there has been a permanent
impairment in the value of goodwill. Any impairment would be recognized when
the sum of expected undiscounted cash flows derived from the acquired business
is less than its carrying value. If such an impairment occurred, the amount of
the impairment would be based on the fair value of the acquired business as
determined by the market value of comparable companies on the present value of
expected cash flows.

        INCOME TAXES. The Company recognizes deferred taxes by the asset and
liability method of accounting for income taxes. Under the asset and liability
method, deferred income taxes are recognized for differences between the
financial-statement and tax bases of assets and liabilities at enacted
statutory tax rates in effect for the years in which the differences are
expected to reverse. The effect on deferred taxes of a change in tax rates is
recognized in income in the period that includes the enactment date. In
addition, valuation allowances are established when necessary to reduce
deferred tax assets to the amounts expected to be realized. The primary sources
of temporary differences are depreciation and amortization of intangible
assets.

        REVENUE AND COST RECOGNITION--SYSTEMS, COMPONENTS AND SERVICE REVENUEs.
Revenue from systems sales is recognized upon shipment, when title passes to
the customer. Subsequent to product shipment, the Company incurs certain
installation costs at the customer's facility and warranty costs which are
estimated and accrued at the time the sale is recognized. Component sales and
service revenues are recognized when goods are shipped or services are rendered
to the customer. Service revenue under contracts with specified service terms
is recognized as earned over the service period in accordance with the terms of
the applicable contract. Costs in connection with the procurement of the
contracts are charged to expense as incurred.

        REVENUE AND COST RECOGNITION--CONTRACT REVENUe. The Company's research
contracts require the development or evaluation of new materials applications
and have a duration of six to thirty-six months. For research contracts with
the U.S. Government and commercial enterprises with duration's greater than six
months, the Company recognizes revenue to the extent of costs incurred plus the
estimated gross profit as stipulated in such contracts, based upon contract
performance. Contracts with a duration of six months or less are accounted for
on the completed contract method. A contract is considered complete when all
costs, except insignificant items, have been incurred, and the research
reporting requirements to the customer have been met. Contract costs include
all direct material and labor costs and those indirect costs related to
contract performance, such as indirect labor, supplies, tools, repairs and
depreciation costs, as well as coverage of certain general and administrative
costs. Provisions for estimated losses on uncompleted contracts are made in the
period in which such losses are determined. Revenues from contracts amounted to
approximately $3,295,000, $614,000 and $438,000 for the years ended September
30, 1996, 1997 and 1998, respectively.

        RESEARCH AND DEVELOPMENT. Research and development costs related to the
development of both present and future products and Company sponsored materials
application research are charged to expense as incurred. In connection with the
acquisition of MicroOptical Devices, Inc. ("MODE"), the Company they recorded a
charge of $29,294,000 for acquired in-process research and development.

        FAIR VALUE OF FINANCIAL INSTRUMENTS. The Company estimates the fair
value of its financial instruments based upon discounted cash flow analyses
using the Company's incremental borrowing rate on similar instruments as the
discount rate. As of September 30, 1998, the fair value of the Company's
subordinated notes exceeded the carrying value of such instruments by
approximately $830,000. As of September 30, 1998, the carrying values of the
Company's cash and cash equivalents, receivables, accounts payable and variable
rate based debt as reflected on the Company's accompanying balance sheet
approximates fair value.

        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. Estimates also affect the reported amounts of
revenues and expenses during the reporting period. Actual results may differ
from those estimates. The Company's most significant estimates relate to
acquired in-process research and development, accounts receivable and inventory
valuation reserves, warranty and installation accruals, estimates of cost and
related gross profits on certain research contracts and the valuation of
long-lived assets.

         NET LOSS PER SHARE. The Company adopted the provisions of Statement of
Financial Accounting Standards No. 128 "Earnings per share" ("SFAS No. 128")
effective with its first quarter. Basic and diluted earnings per share
calculated pursuant to SAFS No. 128 have been restated for all periods
presented to give effect to the Securities and Exchange Commission's Staff
Accounting Bulletin No. 98 which eliminated certain computational requirements
of Staff Accounting Bulletin No. 64.

         Basic earnings per common share was calculated by dividing net loss by
the weighted average number of common stock shares outstanding during the
period. Diluted earnings per share was calculated by dividing net income by the
sum of the weighted average number of common shares outstanding plus all
additional common shares that would have been outstanding if potentially
dilutive common shares had been issued. The following table reconciles the
number of shares utilized in the Company's earnings per share calculations.

RECENT ACCOUNTING PRONOUNCEMENTS

         In June 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 131. "Disclosures
about Segments of an Enterprise and Related Information" ("SFAS No. 131"),
which establishes standards for reporting information about operating segments
in annual financial statements. It also establishes standards for related
disclosures about products and services, geographic areas and major customers.
The Company will be required to adopt this standard in its fiscal year ended
September 30, 1999. The adoption of SFAS No. 131 is not expected to have an
impact on the Company's results of operations, financial position or cash
flows.

         In February 1998, FASB issued SFAS No. 132, "Employers' Disclosures
about Pension and Other Postretirement Benefits" ("SFAS No. 132"), which
revises employers' disclosures about pension and other postretirement benefit
plans. SFAS No. 132 does not change the measurement or recognition of those
plans. SFAS No. 132 is effective for fiscal years beginning after December 15,
1997. The adoption of SFAS No. 132 is not expected to have an impact on the
Company's results of operations, financial position or cash flows.

         In March 1998, the American Institute of Certified Public Accountants
("AICPA") issued Statement of Position ("SOP") 98-1, "Accounting for the Cost
of Computer Software Developed or Obtained for Internal Use" ("SOP 98-1"). SOP
98-1 is effective for financial statements for years beginning after December
14, 1998. SOP 98-1 provides guidance over accounting for computer software
development or obtained for internal use including the requirement to
capitalize specified costs and amortization of such costs. The Company does not
expect the adoption of this standard to have a material effect results of
operations, financial position or cash flows.

         In April 1998, AICPA issued SOP 98-5, "Reporting on the Costs of
Start-Up Activities" ("SOP 98-5"). SOP 98-5, which is effective for fiscal
years beginning after December 15, 1998, provides guidance on the financial
reporting of start-up costs and organization costs. It requires costs of start
up activities and organization costs to be expenses as incurred. As the Company
has expensed these costs historically, the adoption of this standard is not
expected to have a significant impact on its results of operations, financial
position or cash flows.

         RECLASSIFICATIONS. Prior period balances have been reclassified to
conform with the current period financial statement presentation.

NOTE 3.  ACQUISITION

         On December 5, 1997, the Company acquired all of the outstanding
capital stock of MODE in exchange for 1,461,866 shares of EMCORE common stock,
200,966 common stock purchase options (exercise prices ranging from $0.43 to
$0.59), and 47,118 common stock purchase warrants (exercise prices ranging from
$4.32 to $5.92). The purchase price was approximately $32,829,000 including
direct acquisition costs of approximately $500,000. The acquisitions of MODE
was recorded using the purchase method of accounting. Accordingly, the results
of operations of the acquired business and the fair values of the acquired
tangible and intangible assets and assumed liabilities have been included in
the Company's financial statements as of December 5, 1997. The allocation of
the fair value of the net assets acquired is as follows:

         Net tangible assets                              $   156,000
         Goodwill                                           3,379,000
         Acquired in process research and development      29,294,000
                                                          -----------

        Total purchase price                             $32,829,000 
                                                         ===========

         MODE was a development stage company (incorporated in August 1995) and
had 18 employees at the date of acquisition. MODE's activities were
substantially dedicated towards the research and development of micro optical
laser devices at the date of acquisition.

         The amount allocated to acquired in-process research and development
was determined through an independent valuation, which includes a number of
estimates and assumptions. The amount allocated to acquired



                                     -30-

in-process research and development was immediately written-off. Goodwill is
being amortized over a period of three years.

         The following unaudited pro forma basis financial information reflects
the combined results of operations of the Company and MODE, as if MODE had been
acquired as of October 1, 1996. The summary includes the impact of certain
adjustments, such as goodwill amortization and the number of shares
outstanding.

         The unaudited pro forma results of operations are not necessarily
indicative of what actually would have occurred if the acquisition had occurred
on October 1, 1996. In addition, the unaudited pro forma results of operations
are not intended to be a projection of future results that might be achieved
from the combined entity. The foregoing pro forma results of operations does
not reflect the non-recurring write-off of acquired in-process research and
development.

        The Company performs material application research under contract with
the U.S. Government or as a subcontractor of U.S. Government funded projects.

        The Company performs ongoing credit evaluations of its customers'
financial condition and collateral is not requested. The Company maintains
reserves for potential credit losses based upon the credit risk of specified
customers, historical trends and other information. To reduce credit risk and
to fund manufacturing costs, the Company requires periodic prepayments or
irrevocable letters of credit on most production system orders. During the
quarter ended June 30, 1998, the Company wrote off outstanding receivables of
approximately $1.0 million which was due from an Asian customer. Prior to this
event, the Company's credit losses generally had not exceeded its expectations.

NOTE 8.  DEBT FACILITIES

        1998 Agreement:

        On June 22, 1998, the Company entered into an $8.0 million loan
agreement with First Union National Bank (the "1998 Agreement"), which expires
December 31, 1999. The 1998 Agreement bears interest at a rate equal to
one-month LIBOR plus three-quarters of one percent per annum (or 6.4% at
September 30, 1998). As of September 30, 1998, $8.0 million was outstanding
under the 1998 Agreement and is due and payable on December 31, 1999. The 1998
Agreement is guaranteed by both the Company's Chairman and Chief Executive
Officer. In exchange for guaranteeing the facility, the Chairman and the Chief
Executive Officer were granted an aggregate of 284,684 common stock purchase
warrants exercisable at $11.375 per share until May 1, 2001. These warrants are
callable at the Company's option at $0.85 per warrant at such time as the
Company's Common Stock has traded at or above 150% of the exercise price for a
period of thirty days.

        The Company assigned a value of $1,310,000 to the warrants issued to
the guarantors. This valuation was based upon the Company's application of the
Black Scholes Option Pricing Model. This value is accounted for as debt
issuance cost and will be amortized over the eighteen month life of the 1998
Agreement.

        1997 Agreement:

        On March 31, 1997, the Company entered into a $10.0 million loan
agreement (the "1997 Agreement"). The Agreement bears interest at the rate of
Prime plus 50 basis points (8.0% and 9.0% at September 30, 1998 and 1997,
respectively). As of September 30, 1998 the Company had $9,950,000 outstanding
under this facility. As of September 30, 1997, there were no amounts
outstanding under this facility. 

        As a result of the net loss for the quarter ended June 30, 1998, the
Company was not in compliance with the 1997 Agreement fixed charged coverage
ratio covenant. The Company received a waiver from the bank regarding this
non-compliance. The 1997 Agreement was extended to November 30, 1998 and
subsequently further



                                     -33-
<PAGE>   35


extended through October 1, 1999. The 1997 Agreement's financial covenants were
modified under the second extension, and management believes that the Company
will be able to comply with such requirements throughout fiscal 1999. In
addition, the Company's Chairman will guarantee such debt in the event the
Company does not meet certain financial covenants.

        Subordinated Notes:

        On May 1, 1996, the Company issued subordinated notes (the
"Subordinated Notes") in the amount of $9,500,000 to its existing shareholders,
$1,000,000 of which were exchanged for notes receivable from officers and
certain employees with identical payment and interest provisions. The
Subordinated Notes are scheduled to mature on May 1, 2001, and have a stated
interest rate of 6.0% which is payable semi-annually on May 1 and November 1.
In addition, the noteholders were issued 2,328,432 common stock purchase
warrants with an exercise price of $4.08 per share which expire on May 1, 2001.
The warrants are exercisable after November 1, 1996, and are callable at the
Company's option, after May 1, 1997, at $0.85 per warrant. The Company has the
legal right of offset with respect to the notes receivable from officers and
certain key employees, and it is their full intention to offset the
corresponding notes receivable and payable upon maturity. As such, the Company
reflected $848,000 of the officers' and employees' notes receivable as a contra
liability, reducing the Company's Subordinated Notes balance. The remaining
$152,000 note receivable has been reflected as a contra equity note receivable
balance, representing the portion of the employee note receivable associated
with common stock purchase warrants issued to such employees. The Company
received cash proceeds of $8,500,000 in connection with this Subordinated Notes
issuance.

        On September 1, 1996, the Company issued a subordinated note in the
amount of $2,500,000 to the Company's then majority shareholder with terms
identical to the Subordinated Notes issued on May 1, 1996. In addition, under
the terms of this issuance, 245,098 common stock purchase warrants were issued
to purchase common stock at $10.20 per share and which expire September 1,
2001. These warrants are exercisable after March 1, 1997, and are callable at
the Company's option after September 1, 1997, at $0.85 per warrant.

        The Company assigned a value of $1,440,000 to the May 1, 1996
detachable warrants and $900,000 to the September 1, 1996 detachable warrants.
These valuations were based upon the Company's application of Black Scholes and
the Company's assessment of the underlying valuation factors, as well as an
assessment of the terms of the Subordinated Notes. The carrying value of the
Subordinated Notes will be subject to periodic accretions, using the interest
method, in order for the carrying amount to equal the Company's obligation upon
maturity. As a result, the May 1, 1996 and September 1, 1996 Subordinated Notes
have an effective interest rate of approximately 9.3% and 15.0%, respectively.
For the years ended September 30, 1998, 1997 and 1996, imputed warrant interest
related to the subordinated notes amounted to $593,000, $3,988,000 and
$126,000, respectively.

        Demand Note Facilities:

        On September 17, 1998, the Company borrowed $7.0 million from its
Chairman. The loan bears interest at 9.75% per annum. In addition, on October
23, 1998 the Company borrowed an additional $1.5 million from its Chairman on
identical terms. The entire sum of $8.5 million borrowed plus interest was
repaid from the proceeds of the Private Placement.

        On October 25, 1996, the Company entered into a $10.0 million demand
note facility (the "Facility"). The Facility bore interest at the rate of LIBOR
plus 75 basis points, had a term of one year and was due and payable on demand.
The Facility was guaranteed by the Chairman of the Company's Board of Directors
who provided collateral for the Facility. In December 1996, in return for
guaranteeing the facility, the Company granted the Chairman 980,392 common
stock purchase warrants at $10.20 per share which expire September 1, 2001.
These warrants are exercisable after July 1, 1997, and are callable at the
Company's option after December 1, 1997 at $0.85 per warrant. The Facility was
terminated in conjunction with the Company's initial public offering.

        The Company assigned a value of $3,600,000 to the warrants issued to
the guarantor. This valuation was based upon the Company's application of the
Black-Scholes Option Pricing Model ("Black Scholes"). This value was accounted
for as debt issuance cost and was amortized over the expected period that the
facility was to be in place (four months).



                                     -34-
<PAGE>   36


        The Company utilized a portion of the proceeds from its initial public
offering to pay down or discharge certain of its debts. The Company repaid the
entire $8.0 million outstanding under its October 1996 Facility and $2.0
million was used to repay a portion of the Company's outstanding subordinated
notes, due May 1, 2001. In connection with the discharge of the Company's
subordinated notes, an extraordinary loss of $286,000 was recognized.

NOTE 9.  COMMITMENTS AND CONTINGENCIES

        On November 16, 1992, the Company entered into a three-year lease
agreement with a bank for 34,000 square feet of space in the building the
Company presently occupies. On March 31, 1995, the agreement was renewed for 5
years for 49,000 square feet. In November 1996, the Company signed an agreement
to occupy the remaining 26,000 square feet that it previously had not occupied.

        The Company leases certain equipment under non-cancelable operating
leases.

        Facility and equipment rent expense under such leases amounted to
approximately $350,000, $548,000 and $554,000 for the years ended September 30,
1996, 1997 and 1998, respectively.

        Future minimum rental payments under the Company's non-cancelable
operating leases with an initial or remaining term of one year or more as of
September 30, 1998 are as follows:

Period Ending September 30,               Operating

        The Company is from time to time involved in litigation incidental to
the conduct of its business. Management and its counsel believe that such
pending litigation will not have a material adverse effect on the Company's
results of operations, cash flows or financial condition.

        The Company has established a valuation reserve as it has not
determined that it is more likely than not that the net deferred tax asset is
realizable, based upon the Company's past earnings history.

        As of September 30, 1998, the Company has net operating loss
carryforwards for regular tax purposes of approximately $22.0 million which
expire in the years 2003 through 2013. The Company believes that the
consummation of certain equity transactions and a significant change in the
ownership during fiscal years 1995 and 1998 have constituted a change in
control under Section 382 of the Internal Revenue Code ("IRC"). Due to the
change in control, the Company's ability to use its federal net operating loss
carryovers and federal research credit carryovers to offset future income and
income taxes, respectively, are subject to annual limitations under IRC Section
382 and 383.

        The Company believes that the acquisition of MODE and the consummation
of certain other equity transactions has constituted a change in control in
fiscal 1998 under Section 382 of the IRC. As such, Federal net operating loss
carryovers and research credit carryovers incurred subsequent to the Company's
fiscal 1995 change in control (as described above) will also be subject to
annual limitations under IRC Section 382 and 383.

NOTE 11.  STOCKHOLDERS' EQUITY

Reverse Stock Split

        On February 3, 1997, the Board of Directors approved a 3.4:1 reverse
stock split of its common stock and approved a decrease in the number of shares
of common stock authorized. All references in the accompanying financial
statements to the number of common stock and per-share amounts have been
restated to reflect the reverse split.

Common Stock Offering

        In March 1997, the Company completed an initial public offering of
2,500,000 shares of common stock at a price of $9.00 per share (the
"Offering"), and upon the exercise of the Underwriter's overallotment option,
375,000 additional shares of common stock were also sold at $9.00 per share.
The proceeds, net of commissions and certain expenses, to the Company from the
offering were approximately $22.8 million. Prior to the Offering, there was no
public market for the Company's common stock.

Warrant Exercise

        On December 3, 1997, the holders of 1.8 million common stock purchase
warrants (with an exercise price of $4.08) exercised such warrants with the
Company taking full recourse notes amounting to approximately $7.5 million in
exchange for the issued common stock. In addition, the holders are required to
provide collateral at a 2:1 coverage ratio. This collateral is presently held
by the Company.

Preferred Stock

        The Company's certificate of incorporation authorizes the Board of
Directors to issue up to 5,882,353 shares of preferred stock of the Company
upon such terms and conditions having such rights, privileges and preferences
as the Board of Directors may determine.

NOTE 12.  STOCK OPTIONS AND WARRANTS

        STOCK OPTION PLAN. In November 1994, the Company's Incentive Stock
Option Plan, initiated in 1987, was eliminated. On June 5, 1995, the Company
adopted the 1995 Incentive and Non-Statutory Stock Option Plan (the "Option
Plan"). Under the terms of the Option Plan, options to acquire 323,529 shares
of common stock may be granted to eligible employees, as defined, at no less
than 100 percent of the fair market value on the date of grant. In March 1996,
options to acquire an additional 323,530 shares of common stock were approved.

        Certain options under the Option Plan are intended to qualify as
incentive stock options pursuant to Section 422A of the Internal Revenue Code.



                                     -37-
<PAGE>   39


         During fiscal 1998, options with respect to 816,284 shares were granted
pursuant to the Company's Option Plan or issued in connection with the MODE
acquisition at exercise prices ranging from $0.44 to $20.00 per share.

         Stock options granted generally vest over three to five years and are
exercisable over a ten year period. As of September 30, 1996, 1997 and 1998,
options with respect to 162,764, 199,368 and 481,863 shares were exercisable,
respectively.

        The following table summarized the activity under the plan:

        In October 1995, the Financial Accounting Standards Board issued SFAS
No. 123, "ACCOUNTING FOR STOCK BASED COMPENSATION" ("SFAS 123"). SFAS 123
establishes financial and reporting standards for stock based compensation
plans. The Company has adopted the disclosure only provisions of this standard
and has elected to continue to apply the provision of Accounting Principles
Board Opinion No. 25, "Accounting for Stock Issued to Employees". Had the
Company elected to recognize compensation expense for stock options based on
the fair value at the grant dates of awards, net loss and net loss per share
would have been as follows:

        The weighted average fair value of the Company's stock options was
calculated using Black-Scholes with the following weighted-average assumptions
used for grants: No dividend yield; expected volatility of 0% prior to the
Company's initial public offering and 60% thereafter; a risk-free interest rate
of 6.04% and 5.57% for fiscal years 1997 and 1998, respectively, expected lives
of 5 years. The weighted average fair value of options granted during the years
ended September 30, 1997 and 1998 is $3.82 and $7.50 per share, respectively.
Stock options granted by the Company prior to its initial public offering were
valued using the minimum value method under FASB No. 123.

NOTE 13.  RELATED PARTIES

        In May 1995, 52% of the Company's outstanding shares of Common Stock
were purchased by Jesup & Lamont Merchant Partners, L.L.C. ("JLMP"). Prior to
May 12, 1997, a majority of the Company's then six directors were members of
JLMP. On May 12, 1997, JLMP distributed all of its shares of the Company to the
individual members of JLMP. In May 1995, the Company entered into a consulting
agreement (the "Agreement") with Jesup & Lamont Capital Markets, Inc. ("Jesup &
Lamont") pursuant to which Jesup & Lamont agreed to provide financial advisory
and employee services for the Company for one year. Total fees paid to Jesup &
Lamont amounted to approximately $241,697 for the fiscal year ended September
30, 1996. No fees were paid to Jesup & Lamont during the fiscal years ended
September 30, 1998 and 1997.

        In December 1996, the Company's chairman and chief executive officer
retired. The Company entered into a consulting agreement with him for a term of
two years and will provide compensation of $250,000 per annum. In addition, the
Company has also forgiven $115,300 of his indebtedness to the Company and had
agreed to extend the period for the exercise of his vested stock options
through March 1997 and accordingly he exercised all 26,471 vested shares.

        In fiscal 1997, the Company entered into a non-exclusive and
non-refundable technology licensing and royalty agreement with Uniroyal
Technology Corporation ("UTC") for the process technology to develop and
manufacture high brightness light emitting diodes ("LEDs"). During fiscal 1998
and 1997, revenue associated with the UTC licensing agreement amounted to $2.5
million and $2.5 million, respectively. At the time the transaction was
originally entered into, UTC's Chairman and CEO was a member of EMCORE's Board
of Directors and EMCORE's Chairman was on the Board of Directors of UTC. All
related party accounts receivable for fiscal 1997 have been paid in full. As of
September 30, 1998, the Company had an outstanding related party receivable of
$500,000.

        In July 1998, the Company and a wholly-owned subsidiary of UTC entered
into a venture to produce and market compound semi-conductor products. The
Company has a 49% non-controlling minority interest. The Company's rights under
the venture agreement are protective and as such, the Company accounts for its
interest in the venture under the equity method of accounting. The investment
in this venture amounted to $490,000 as of September 30, 1998, and has been
classified as a component of other long-term assets. For the year ended
September 30, 1998, the Company recognized a loss of $198,000 related to this
venture, which has been recorded as a component of other income and expense.

         The President of Hakuto Co. Ltd. ("Hakuto"), the Company's Asian
distributor, is a member of the Company's Board of Directors and Hakuto is a
minority shareholder of the Company. During the year ended September 30, 1998,
sales made through Hakuto approximated $9.2 million.

        On June 22, 1998, the Company entered into the 1998 Agreement. The 1998
Agreement was guaranteed by the Chairman and the Chief Executive Officer of the
Company (see Note 8). In return for guaranteeing the facility, the Company
granted the Chairman and the Chief Executive Officer an aggregate of 284,684
common stock purchase warrants at $11.375 per share which expire May 1, 2001.
These warrants are callable at the Company's option at $0.85 per warrant at such
time as the Company's common stock has traded at or above 150% of the exercise
price for a period of 30 days.

        On September 17, 1998, the Company borrowed $7.0 million from its
Chairman, Thomas J. Russell. The loan bears interest at 9.75% per annum. In
addition, on October 23, 1998 the Company borrowed an additional $1.5 million
from its Chairman on identical terms. The entire $8.5 million, borrowed from
Mr. Russell was repaid from the proceeds of a private placement (See Note 8).

NOTE 16.  EMPLOYEE SAVINGS PLAN

        The Company has a savings plan (the "Savings Plan") that qualifies as a
deferred salary arrangement under Section 401(k) of the Internal Revenue Code.
Under the Savings Plan, participating employees may defer a portion of their

Effective August 1, 1997, the Company began contributing to the Savings Plan.

approximately $500,000. The shares of Series I Preferred Stock are convertible,
at any time, at the option of the holders thereof, unless previously redeemed,
into shares of Common Stock at an initial conversion price of $14.00 per share
of Common Stock, subject to adjustment in certain cases. The Series I Preferred
Stock is redeemable, in whole or in part, at the option of the Company at any

REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and
Shareholders of EMCORE Corporation

         In our opinion, the accompanying consolidated balance sheets and the
related consolidated statements of operations, shareholders' equity and cash
flows present fairly, in all material respects, the financial position of EMCORE
Corporation and its subsidiaries at September 30, 1998 and 1997, and the results
of their operations and their cash flows for each of the three years in the
period ended September 30, 1998, in conformity with generally accepted
accounting principles. In addition, in our opinion, the financial statement
schedule listed in the index appearing under Item 14(a)(2) presents fairly, in
all material respects, the information set forth therein when read in
conjunction with the related consolidated financial statements. These financial
statements and financial statement schedule are the responsibility of the
Company's management; our responsibility is to express an opinion on these
financial statements and financial statement schedule based on our audits. We
conducted our audits of these statements in accordance with generally accepted
auditing standards which 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, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

         As discussed in Note 2 (Net loss per share), the Company has changed
its method of calculating earnings per basic and diluted common share.

         STATEMENT OF MANAGEMENT RESPONSIBILITY FOR FINANCIAL STATEMENTS




To the Shareholders of
     EMCORE Corporation:

        Management has prepared and is responsible for the consolidated
financial statements and related information in the Annual Report. The financial
statements, which include amounts based on judgment, have been prepared in
conformity with generally accepted accounting principles consistently applied.

        Management has developed, and in 1998 continued to strengthen, a system
of internal accounting and other controls for the Company. Management believes
these controls provide reasonable assurance that assets are safeguarded from
loss or unauthorized use and that the Company's financial records are a reliable
basis for preparing the financial statements. Underlying the concept of
reasonable assurance is the premise that the cost of control should not exceed
the benefit derived.

        The Board of Directors, through its audit committee, is responsible for
reviewing and monitoring the Company's financial reporting and accounting
practices. The audit committee meets regularly with management and independent
accountants - both separately and together. The independent accountants have
free access to the audit committee to review the results of their audits, the
adequacy of internal accounting controls and the quality of financial reporting.

                  3.       DIVIDENDS.

                           (a) The holders of shares of the Series I Preferred
Stock shall be entitled to receive, when, as and if declared by the Board of
Directors out of funds legally available therefor, cumulative cash dividends at
an annual rate of 2% of the liquidation preference per share (an amount
initially equivalent to $.28 per annum per share) of Series I 



                                      -3-
<PAGE>   4

Preferred Stock, payable at the option of the Company in cash or additional duly
and validly issued, fully paid and non-assessable shares of Series I Preferred
Stock, free from all taxes, liens and charges with respect to the issuance
thereof, which will be valued at the liquidation preference (without giving
effect to accrued and unpaid dividends) as of the relevant dividend payment
record date. Notwithstanding the foregoing, the Company shall not be required to
issue fractional shares of Series I Preferred Stock; the Company may elect, in
its sole discretion, independently for each holder, whether such number of
shares (on an aggregated basis) will be rounded up to the nearest whole share or
whether such holder will be given cash in lieu of any fractional shares. Such
dividends shall be cumulative from the Issue Date, whether or not in any
Dividend Period or Periods there shall be funds of the Company legally available
for the payment of such dividends and whether or not such dividends are declared
and shall be payable quarterly, when, as and if declared by the Board of
Directors on March 31, June 30, September 30 and December 31 in each year (each
a "dividend payment date"), commencing on December 31, 1998. If December 31,
1998 or any other dividend payment date shall be on a day other than a Business
Day, then the dividend shall be payable on the next following Business Day.
Dividends are payable in arrears to the holders of record of shares of the
Series I Preferred Stock, as they appear on the stock records of the Company at
the close of business on those dates (each such date, a "dividend payment record
date"), not less than 10 days nor more than 60 days preceding the dividend
payment dates thereof, as shall be fixed by the Board of Directors. Dividends on
the Series I Preferred Stock shall accrue (whether or not declared) on a daily
basis from the Issue Date and accrued dividends for each Dividend Period shall
accumulate to the extent not paid on the dividend payment date first following
the Dividend Period for which they accrue. As used herein, the term "accrued"
with respect to dividends includes both accrued and accumulated dividends.
Accrued and unpaid dividends for any past Dividend Periods may be declared and
paid at any time, without reference to any regular dividend payment date, to
holders of record on the record date, not less than 10 nor more than 60 days
preceding the payment date thereof, as may be fixed by the Board of Directors.

                           (b) The amount of dividends payable for each full
Dividend Period for the Series I Preferred Stock shall be computed by dividing
the annual dividend rate by four (rounded to the nearest tenth of a cent). The
amount of dividends payable for the initial Dividend Period on the Series I
Preferred Stock, or any other period shorter or longer than a full Dividend
Period on the Series I Preferred Stock, shall be computed on the basis of a
360-day year consisting of twelve 30-day months. Holders of shares of Series I
Preferred Stock called for redemption on a redemption date falling between the
close of business on a dividend payment record date and the close of business on
the corresponding dividend payment date shall, in lieu of receiving such
dividend on the dividend payment date fixed therefor, receive such dividend
payment together with all other accrued and unpaid dividends on the date fixed
for redemption (unless such holder converts such shares in accordance with
Section 7 hereof). Holders of shares of Series I Preferred Stock shall not be
entitled to any dividends, whether payable in cash, property or securities, in
excess of cumulative dividends, as herein provided, on the Series I Preferred
Stock. No interest, or sum of money in lieu of interest, shall be payable in
respect of any dividend payment or payments on the Series I Preferred Stock
which are in arrears.

                           (c) So long as any shares of the Series I Preferred
Stock are outstanding, no dividends, except as described in the next succeeding
sentence, shall be declared or paid or set apart for payment on any class or
series of stock of the Company ranking, as to dividends, on a parity with the
Series I Preferred Stock, for any period unless full cumulative dividends have
been or contemporaneously are declared and paid or declared and a sum sufficient
for the payment thereof is set apart for such payment on the Series I Preferred
Stock for all Dividend Periods terminating on or prior to the date of payment,
or setting apart for payment, of such dividends on such parity stock. When
dividends are not paid in full or a sum sufficient for such payment is not set
apart, as aforesaid, upon the shares of the Series I Preferred Stock and any
other class or series of stock ranking on a parity as to dividends with the
Series I Preferred Stock, all dividends declared upon shares of the Series I
Preferred Stock and all dividends declared upon such other stock shall be
declared pro rata so that the amounts of dividends per share declared on the
Series I Preferred Stock and such other stock shall in all cases bear to each
other the same ratio that accrued dividends per share on the shares of the
Series I Preferred Stock and on such other stock bear to each other.

                           (d) So long as any shares of the Series I Preferred
Stock are outstanding, no other stock of the Company ranking on a parity with
the Series I Preferred Stock as to dividends or upon liquidation, dissolution or
winding up shall be redeemed, purchased or otherwise acquired for any
consideration (or any moneys be paid to or made available for a sinking fund or
otherwise for the purchase or redemption of any shares of any such stock) by the
Company (except by conversion into or exchange for stock of the Company ranking
junior to the Series I Preferred Stock as to dividends and upon liquidation,
dissolution or winding up) unless (i) the full cumulative dividends, if any,
accrued on all outstanding shares of the Series I Preferred Stock shall have
been paid or set apart for payment for all past Dividend Periods and (ii)
sufficient funds shall have been set apart for the payment of the dividend for
the current Dividend Period with respect to the Series I Preferred Stock and for
the current dividend period with respect to any other stock of the Company
ranking on a parity with the Series I Preferred Stock as to dividends.

                           (e) So long as any shares of the Series I Preferred
Stock are outstanding, no dividends (other than dividends or distributions paid
in shares of, or options, warrants or rights to subscribe for or purchase shares
of, Common Stock or other stock ranking junior to the Series I Preferred Stock
as to dividends and upon liquidation, dissolution or winding up) shall be
declared or paid or set apart for payment and no other distribution shall be
declared or made or set apart for payment, in each case, upon the Common Stock
or other stock of the Company ranking junior to the Series I Preferred Stock as
to dividends or upon liquidation, dissolution or winding up, nor shall any
Common Stock nor any other such stock of the Company ranking junior to the
Series I Preferred Stock as to dividends or upon liquidation, dissolution or
winding up be redeemed, purchased or otherwise acquired for any consideration
(or any moneys be paid to or made available for a sinking fund or otherwise for
the purchase or redemption of any shares of any such stock) by the Company
(except by conversion into or exchange for stock of the Company ranking junior
to the Series I Preferred Stock as to dividends and upon liquidation,
dissolution or winding up) unless, in each case (i) the full cumulative
dividends, if any, accrued on all outstanding shares of the Series I Preferred
Stock and any other 



                                      -5-
<PAGE>   6

stock of the Company ranking on a parity with the Series I Preferred Stock as to
dividends shall have been paid or set apart for payment for all past Dividend
Periods and all past dividend periods with respect to such other stock and (ii)
sufficient funds shall have been set apart for the payment of the dividend for
the current Dividend Period with respect to the Series I Preferred Stock and for
the current dividend period with respect to any other stock of the Company
ranking on a parity with the Series I Preferred Stock as to dividends.

                  4.       LIQUIDATION PREFERENCE.

                           (a) In the event of any liquidation, dissolution or
winding up of the Company, whether voluntary or involuntary, the holders of the
shares of Series I Preferred Stock shall be entitled to receive out of assets of
the Company available for distribution to shareholders $14.00 per share (as
adjusted for any stock combinations or splits with respect to the Series I
Preferred Stock) plus an amount per share equal to all dividends (whether or not
earned or declared) accrued and unpaid thereon to the date of final distribution
to such holders (collectively, the "Liquidation Preference") before any payment
or distribution of the assets of the Company (whether capital or surplus) shall
be made to or set apart for the holders of Common Stock or any other series or
class or classes of stock of the Company ranking junior to the Series I
Preferred Stock upon liquidation, dissolution or winding up of the Company and
no payments or distributions of any assets of the Company shall be made to the
holders of any class or series of stock ranking on a parity with the Series I
Preferred Stock in respect of the distribution of assets upon dissolution,
liquidation or winding up unless there shall likewise be paid at the same time
to the holders of the Series I Preferred Stock a like proportionate amount
determined ratably in proportion to the full amounts to which the holders of all
outstanding shares of Series I Preferred Stock and the holders of all
outstanding shares of such parity stock are respectively entitled with respect
to such distribution. If, upon any liquidation, dissolution or winding up of the
Company, the assets of the Company, or proceeds thereof, distributable among the
holders of the shares of Series I Preferred Stock shall be insufficient to pay
in full the preferential amount aforesaid and liquidating payments on any other
shares of stock ranking, as to the liquidation, dissolution or winding up, on a
parity with the Series I Preferred Stock, then such assets, or the proceeds
thereof, shall be distributed among the holders of shares of Series I Preferred
Stock and any such other stock ratably in accordance with the respective amounts
which would be payable on such shares of Series I Preferred Stock and any such
other stock if all amounts payable thereon were paid in full. For the purposes
of this Section 4, (i) a consolidation or merger of the Company with one or more
corporations or other entities, (ii) a sale, lease, exchange or transfer of all
or any part of the Company's assets or (iii) a statutory share exchange shall
not be deemed to be a liquidation, dissolution or winding up of the Company,
voluntary or involuntary.

                           (b) Subject to the rights of the holders of shares of
any series or class of stock ranking on a parity with the Series I Preferred
Stock upon liquidation, dissolution or winding up, upon any liquidation,
dissolution or winding up of the Company, after payment shall have been made in
full to the holders of Series I Preferred Stock, as provided in this Section 4,
any other series or class or classes of stock ranking junior to the Series I
Preferred Stock upon liquidation, dissolution or winding up shall, subject to
the respective terms and provisions (if 




                                      -6-
<PAGE>   7

any) applying thereto, be entitled to receive any and all assets remaining to be
paid or distributed, and the holders of Series I Preferred Stock shall not be
entitled to share therein.

                           (c) Written notice of any liquidation, dissolution or
winding up of the Company, stating the payment date or dates when and the place
or places where the amounts distributable in such circumstances shall be
payable, shall be given by first class mail, postage prepaid, not less than 30
days prior to any payment date stated therein, to the holders of record of the
Series I Preferred Stock at their respective addresses as the same shall appear
on the books of the Transfer Agent.

                  5.       REDEMPTION.

                           (a) Except as provided in Section 5(b) hereof, the
shares of Series I Preferred Stock may not be redeemed by the Company prior to
such date as the Closing Price of the Company's Common Stock is $28.00 or more
per share for 30 consecutive Trading Dates, on or after which the Company, at
its option, may redeem the shares of the Series I Preferred Stock, in whole or
in part, at any time or from time to time out of funds legally available
therefor, subject to the notice provisions and provisions for partial redemption
described below, at a price equal to $14.00 per share (as adjusted for any stock
combinations or splits with respect to the Series I Preferred Stock) plus a cash
amount equal to accrued and unpaid dividends, if any, to (and including) the
date of redemption.

                           (b) The Company shall redeem all outstanding shares
of the Series I Preferred Stock on November 17, 2003 at a price of $14.00 per
Share (as adjusted for any stock combinations or splits with respect to the
Series I Preferred Stock), plus accrued and unpaid dividends.

                           (c) In the event the Company shall redeem shares of
Series I Preferred Stock pursuant to Section 5(a) or 5(b) hereof, notice of such
redemption shall be given not less than 30 nor more than 60 days prior to the
redemption date, to each holder of record of the shares to be redeemed, at such
holder's address as the same appears on the stock records of the Company. Each
such notice shall state: (i) the redemption date; (ii) the number of shares of
Series I Preferred Stock to be redeemed and, if less than all the shares held by
such holder are to be redeemed, the number of such shares to be redeemed from
such holder; (iii) the redemption price; (iv) the place or places where
certificates for such shares are to be surrendered for payment of the redemption
price; (v) the then current conversion price; (vi) that dividends on the shares
to be redeemed shall cease to accrue on such redemption date and (vii) that
shares of Series I Preferred Stock called for redemption may be converted at any
time prior to the close of business on the date of redemption. Notice having
been given as aforesaid, from and after the redemption date, unless the Company
shall be in default in providing money for the payment of the redemption price
(including any accrued and unpaid dividends to (and including) the date fixed
for redemption), (i) dividends on the shares of the Series I Preferred Stock so
called for redemption shall cease to accrue, (ii) said shares shall be deemed no
longer outstanding, and (iii) all rights of the holders thereof as shareholders
of the Company (except the right to receive from the Company the moneys payable
upon redemption without interest thereon) shall cease. The 




                                      -7-
<PAGE>   8

Company's obligation to provide moneys in accordance with the preceding sentence
shall be deemed fulfilled if, on or before the redemption date, the Company
shall deposit with a bank or trust company having a capital and surplus of at
least $50,000,000, funds necessary for such redemption, in trust for the account
of the holders of the shares to be redeemed (and so as to be and continue to be
available therefor), with irrevocable instructions and authority to such bank or
trust company that such funds be applied to the redemption of the shares of
Series I Preferred Stock so called for redemption. Any interest accrued on such
funds shall be paid to the Company from time to time. Any funds so deposited and
unclaimed at the end of three years from such redemption date shall be released
or repaid to the Company, after which, subject to any applicable laws relating
to escheat or unclaimed property, the holder or holders of such shares of Series
I Preferred Stock so called for redemption shall look only to the Company for
payment of the redemption price.

                  (d) Upon surrender in accordance with said notice of the
certificates for any such shares so redeemed (properly endorsed or assigned for
transfer, if the Board of Directors shall so require and the notice shall so
state), such shares shall be redeemed by the Company at the applicable
redemption price aforesaid. If fewer than all the outstanding shares of Series I
Preferred Stock are to be redeemed, shares to be redeemed shall be selected by
the Company from outstanding shares of Series I Preferred Stock not previously
called for redemption by lot or pro rata (as near as may be). If fewer than all
the shares represented by any certificate are redeemed, a new certificate shall
be issued representing the unredeemed shares without cost to the holder thereof.

                  (e) Notwithstanding the foregoing, if notice of redemption has
been given pursuant to this Section 5 and any holder of shares of Series I
Preferred Stock shall, prior to the close of business on the redemption date,
give written notice to the Company pursuant to Section 7(b) hereof of the
conversion of any or all of the shares to be redeemed held by such holder
(accompanied by a certificate or certificates for such shares, duly endorsed or
assigned to the Company), then the conversion of such shares to be redeemed
shall become effective as provided in Section 7.

                  6. SHARES TO BE RETIRED. All shares of Series I Preferred
Stock purchased, redeemed, exchanged or converted by the Company shall be
retired and canceled and shall be restored to the status of authorized but
unissued shares of Preferred Stock, without designation as to series, and may
thereafter be reissued.

                  7. CONVERSION. Holders of shares of Series I Preferred Stock
shall have the right to convert all or a portion of such shares (including
fractions of such shares) into shares of Common Stock, as follows:

                           (a) Subject to and upon compliance with the
provisions of this Section 7, a holder of shares of Series I Preferred Stock
shall have the right, at such holder's option, at any time (except that, with
respect to any shares called for redemption or exchange, such right shall
terminate at the close of business on the date fixed for redemption or exchange
of such shares) to convert any of such shares (or fractions thereof) into the
number of fully paid and non-




                                      -8-
<PAGE>   9

assessable shares of Common Stock (as such shares shall then be constituted)
obtained by dividing the aggregate liquidation preference of the shares to be
converted by the Conversion Price and by surrender of such shares, such
surrender to be made in the manner provided in Section 7(b). Subject to the
following provisions of this Section 7(a), any shares of Series I Preferred
Stock may be converted, at the option of its holder, in part into Common Stock
under the procedure set forth above. If a part of a share of Series I Preferred
Stock is converted, then the Company will convert such share into the
appropriate number of shares of Common Stock (subject to Section 7(c)). No
fractional shares or securities representing fractional shares of Common Stock
will be issued upon conversion; in lieu of fractional shares of Common Stock,
the Company will pay a cash adjustment based upon the Closing Price of the
Common Stock at the close of business on the first Trading Date preceding the
date of conversion.

                           (b) In order to exercise the conversion right, the
holder of each share of Series I Preferred Stock (or fraction thereof) to be
converted shall surrender the certificate representing such share, duly endorsed
or assigned to the Company or in blank, at the office of the Transfer Agent,
which shall initially be the Company, accompanied by funds, if any, required by
the last paragraph of this Section 7(b), and shall give written notice to the
Company in the form set forth on the reverse of the stock certificates for the
Series I Preferred Stock that the holder thereof elects to convert such Series I
Preferred Stock or a specified portion thereof. Such notice shall also state the
name or names (with address) in which the certificate or certificates for shares
of Common Stock which shall be issuable upon such conversion shall be issued,
and shall be accompanied by funds in an amount sufficient to pay any transfer or
similar tax resulting from the issuance of certificates in a name other than the
name of the holder of the Series I Preferred Stock. Each share surrendered for
conversion shall, unless the shares issuable on conversion are to be issued in
the same name as the name in which such share of Series I Preferred Stock is
registered, be duly endorsed by, or be accompanied by instruments of transfer
(in each case, in form satisfactory to the Company), duly executed by the holder
or such holder's duly authorized attorney.

                           As promptly as practicable after the surrender of
certificates for shares of Series I Preferred Stock for conversion and the
receipt of such notice and funds, if any, as aforesaid, the Company shall issue
and shall deliver at such office to such holder, or on such holder's written
order, a certificate or certificates for the number of full shares of Common
Stock issuable upon the conversion of such shares of Series I Preferred Stock in
accordance with the provisions of this Section 7, a certificate or certificates
representing any shares of Series I Preferred Stock not so surrendered for
conversion but previously evidenced by the stock certificate representing shares
of Series I Preferred Stock surrendered for conversion and a check or cash in
respect of any fractional interest in respect of a share of Common Stock arising
upon such conversion, as provided in Section 7(c).

                           Each conversion shall be deemed to have been effected
immediately prior to the close of business on the date on which the certificates
for shares of Series I Preferred Stock shall have been surrendered (accompanied
by the funds, if any, required by the last paragraph of this section 7(b)) and
such notice shall have been received by the Company as aforesaid, and the person
or persons in whose name or names any certificate or certificates for shares of
Common 




                                      -9-
<PAGE>   10

Stock shall be issuable upon such conversion shall be deemed to have become on
said date the holder or holders of record of the shares represented thereby;
provided, however, that any surrender on any date when the stock transfer books
of the Company shall be closed shall cause the person or persons in whose name
or names the certificates are to be issued to become the holder or holders of
record thereof for all purposes on the next succeeding day on which such stock
transfer books are open, but such conversion shall be at the Conversion Price in
effect on the date upon which such shares shall have been surrendered. All
shares of Common Stock delivered upon conversion of the Series I Preferred Stock
will, upon delivery, be duly and validly issued, fully paid and nonassessable,
free from all taxes, liens and charges with respect to the issuance thereof.

                           If a Holder shall surrender a share of Series I
Preferred Stock for conversion during the period from the close of business on
any dividend payment record date to the close of business on the following
dividend payment date, such holder shall nevertheless be entitled to receive the
dividend payable on such shares on such dividend payment date notwithstanding
the conversion thereof following the close of business on such former dividend
payment record date and prior to the close of business on such latter dividend
payment date. However, shares of Series I Preferred Stock surrendered for
conversion during the period between the close of business on any dividend
payment record date and the close of business on the corresponding dividend
payment date (except shares called for redemption or exchange on a redemption
date or exchange date during such period) must be accompanied by payment of an
amount equal to the dividend payment for the then current Dividend Period with
respect to such share of Series I Preferred Stock presented for conversion on
such dividend payment date; provided, however, that no such payment need be made
if, at the time of conversion, dividends payable on the shares of Series I
Preferred Stock outstanding shall be in arrears for more than 30 days beyond the
previous dividend payment date. The dividend payment with respect to shares of
Series I Preferred Stock which are called for redemption on a redemption date
during the period from the close of business on a dividend payment record date
to the close of business on the corresponding dividend payment date shall be
payable on such dividend payment date to the holder of record of such shares on
the books of the Company at the close of business on the dividend payment record
date notwithstanding the conversion of such shares during the period between the
close of business on such dividend payment record date and the close of business
on such dividend payment date, and the holder of such shares need not make a
payment equal to the dividend payment amount upon surrender of such shares for
conversion. A holder of shares of Series I Preferred Stock on a dividend payment
record date will receive the dividend payable by the Company on such shares of
Series I Preferred Stock surrendered for conversion. Except as provided above,
the Company shall make no payment or allowances for unpaid dividends, whether or
not in arrears, on converted shares or for dividends on the shares of Common
Stock issued upon such conversion.

                           (c) In connection with the conversion of any shares
of Series I Preferred Stock, fractions of such shares may be converted; however,
no fractional shares or scrip representing fractions of shares of Common Stock
shall be issued upon conversion of the Series I Preferred Stock. If more than
one share (or fraction thereof) shall be surrendered for conversion at one time
by the same holder, the number of full shares of Common Stock issuable upon




                                      -10-
<PAGE>   11

conversion thereof shall be computed on the basis of the aggregate number of
shares of Series I Preferred Stock so surrendered. If any fractional share of
Common Stock would otherwise be issuable upon the conversion of a share of
Series I Preferred Stock (or fraction thereof), the Company shall make an
adjustment therefor in cash (computed to the nearest cent) equal to the Closing
Price of Common Stock on the Trading Date immediately preceding the date of
conversion multiplied by the fraction of a share of Common Stock otherwise
issuable.

                           (d) The Conversion Price shall be adjusted from time
to time by the Company as follows:

                                    (i) This section intentionally omitted.

                                    (ii) In case the Company shall issue after
         the Issue Date rights or warrants to all holders of Common Stock
         entitling them to subscribe for or purchase Common Stock at a price per
         share less than the Current Market Price per share of Common Stock at
         the record date for the determination of shareholders entitled to
         receive such rights or warrants, then the Conversion Price in effect
         immediately prior thereto shall be adjusted to equal the price
         determined by multiplying (A) the Conversion Price in effect
         immediately prior to the date of issuance of such rights or warrants by
         (B) a fraction, the numerator of which shall be the sum of (1) the
         number of shares of Common Stock outstanding on the date of issuance of
         such rights or warrants (without giving effect to any such issuance)
         and (2) the number of shares of Common Stock which the aggregate
         proceeds from the exercise of such rights or warrants for Common Stock
         would purchase at such Current Market Price, and the denominator of
         which shall be the sum of (1) the number of shares of Common Stock
         outstanding on the date of issuance of such rights or warrants (without
         giving effect to any such issuance) and (2) the number of additional
         shares of Common Stock offered for subscription or purchase. Such
         adjustment shall be made successively whenever any such rights or
         warrants are issued, and shall become effective immediately after such
         record date. In determining whether any rights or warrants entitle the
         holder of Common Stock to subscribe for or purchase shares of Common
         Stock at less than such Current Market Price, there shall be taken into
         account any consideration received by the Company upon issuance and
         upon exercise of such rights or warrants, the value of such
         consideration, if other than cash, to be reasonably determined in good
         faith by the Board of Directors.

                                    (iii) In case the Company shall pay a
         dividend or make a distribution to all holders of its Common Stock
         after the Issue Date of any shares of capital stock of the Company or
         its subsidiaries (other than Common Stock, which shall be subject to
         adjustment pursuant to Section 7(d)(vi)) or evidences of indebtedness
         of the Company or its subsidiaries or assets (including securities, but
         excluding those rights, warrants, dividends and distributions referred
         to in subparagraph (ii) and (vi) of this Section 7(d)), excluding
         dividends or distributions in connection with the liquidation,
         dissolution or winding up of the Company and excluding cash dividends
         referred to in subparagraph (v) of this Section 7(d) then in each such
         case, the Conversion Price shall be adjusted so that it shall equal the
         price determined by multiplying (A) the Conversion 




                                      -11-
<PAGE>   12

         Price in effect on the record date mentioned below by (B) a fraction,
         the numerator of which shall be the Current Market Price per share of
         the Common Stock on the record date mentioned below less the then fair
         market value (as determined by the Board of Directors, whose
         determination shall, if made in good faith, be conclusive) as of such
         record date of the portion of the capital stock or evidences of
         indebtedness or assets so distributed or of such rights or warrants
         applicable to one share of Common Stock, and the denominator of which
         shall be the Current Market Price per share of the Common Stock on such
         record date. Such adjustment shall become effective immediately, except
         as provided in Section 7(h) below, after the record date for the
         determination of shareholders entitled to receive such distribution.

                                    (iv) Notwithstanding anything in
         subparagraphs (ii) and (iii) of this Section 7(d), if such rights or
         warrants shall by their terms provide for an increase or increases (or
         decrease or decreases) with the passage of time or otherwise in the
         price payable to the Company upon the exercise thereof, the Conversion
         Price upon any such increase or decrease becoming effective shall
         forthwith be readjusted (but, in case of an increase or increases in
         exercise price, to no greater extent than originally adjusted by reason
         of such issuance or sale) to reflect the same. Upon the expiration or
         termination of such rights or warrants, if any such rights or warrants
         shall not have been exercised, then the Conversion Price shall
         forthwith be readjusted and thereafter be the rate which it would have
         been had an adjustment been made on the basis that (A) the only rights
         or warrants issued or sold were those so exercised and they were issued
         or sold for the consideration actually received by the Company for the
         granting of all such options, rights or warrants whether or not
         exercised and (B) the Company issued and sold a number of shares of
         Common Stock equal to those actually issued upon exercise of such
         rights, and such shares were issued and sold for a consideration equal
         to the aggregate exercise price in effect under the exercise rights
         actually exercised at the respective dates of their exercise. For
         purposes of subparagraphs (ii) and (iii) of this Section 7(d), the
         aggregate consideration received by the Company in connection with the
         issuance of shares of Common Stock or of rights or warrants shall be
         deemed to be equal to the sum of the aggregate offering price (before
         deduction of underwriting discounts or commissions and expenses payable
         to third parties) of all such securities plus the minimum aggregate
         amount, if any, payable upon the exercise of such rights or warrants
         into shares of Common Stock.

                                    (v) In case the Company shall, by dividend
         or otherwise, at any time distribute to all holders of the Common Stock
         cash (excluding any cash that is distributed as part of a distribution
         referred to in subparagraph (iii) of this Section 7(d) or in connection
         with a transaction to which Section 7(e) applies) in an aggregate
         amount that, together with (A) the aggregate amount of any other
         distributions to all holders of the Common Stock made exclusively in
         cash within the 12 months preceding the date fixed for the
         determination of shareholders entitled to such distribution and in
         respect of which no Conversion Price adjustment has been made
         previously and (B) the aggregate amount of any cash plus the fair
         market value (as determined by the Board of Directors, whose
         determination shall, if made in good faith, be conclusive) as of such
         date of 




                                      -12-
<PAGE>   13

         determination of any other consideration payable in respect of any
         tender or exchange offer or other purchase by the Company or a
         subsidiary of the Company for all or any portion of the Common Stock
         consummated within 12 months preceding such date of determination and
         in respect of which no Conversion Price adjustment has been made
         previously, exceeds 5.0% of the product of the Current Market Price per
         share of Common Stock multiplied by the number of shares of Common
         Stock outstanding on such date, then in each such case the Conversion
         Price shall be reduced (but not increased) so that it shall equal the
         price obtained by multiplying the Conversion Price in effect
         immediately prior to the close of business on such date of
         determination by a fraction of which the numerator shall be (x) the
         product of the Current Market Price per share of Common Stock on such
         date, multiplied by the number of shares of Common Stock outstanding on
         such date, less (y) the sum of (i) the aggregate amount of cash to be
         distributed at such time, (ii) the aggregate amount of any other
         distributions to holders of Common Stock made exclusively in cash
         within the preceding 12 months, in respect of which no Conversion Price
         adjustment has been made previously, and (iii) the aggregate amount of
         any cash plus the fair market value (determined as aforesaid) of any
         other consideration payable in respect of any tender or exchange offer
         or other purchase by the Company or a subsidiary of the Company for all
         or any portion of the Common Stock within the preceding 12 months, in
         respect of which no Conversion Price adjustment has been made
         previously; and the denominator shall be the product of such Current
         Market Price, multiplied by the number of shares of Common Stock
         outstanding on such date. Such reduction shall become effective
         immediately prior to the opening of business on the date after such
         determination.

                                    (vi) In case outstanding shares of Common
         Stock shall be subdivided into a greater number of shares of Common
         Stock or in case the Company effects a dividend of Common Stock to the
         holders of its Common Stock, the Conversion Price in effect at the
         opening of business on the day following the day upon which such
         subdivision becomes effective or the record date of such dividend, as
         the case may be, shall be proportionately reduced, and, conversely in
         case outstanding shares of Common Stock shall be combined into a
         smaller number of shares of Common Stock, the conversion price in
         effect at the opening of business on the day following the day upon
         which such combination becomes effective shall be proportionately
         increased, such reduction or increase, as the case may be, to become
         effective immediately after the opening of business on the day
         following the day upon which such subdivision or combination becomes
         effective.

                                    (vii) The reclassification of Common Stock
         into securities which include securities other than Common Stock (other
         than any reclassification upon a consolidation or merger) shall be
         deemed to involve (i) a distribution of such securities other than
         Common Stock to all holders of Common Stock (and the effective date of
         such reclassification shall be deemed to be the "date fixed for a
         determination of shareholders entitled to such distribution" within the
         meaning of paragraph (iii) of this Section and (ii) a subdivision or
         combination, as the case may be, of the number of shares of Common
         Stock outstanding immediately prior to such reclassification into the
         number of shares of 




                                      -13-
<PAGE>   14

         Common Stock outstanding immediately thereafter (and the effective date
         of such reclassification shall be deemed to be "the day upon which such
         subdivision becomes effective" or "the day upon which such combination
         becomes effective," as the case may be, and "the day upon which such
         subdivision or combination becomes effective" within the meaning of
         paragraph (vi) of this Section). Rights or warrants issued by the
         Company to all holders of the Common Stock that entitle the holders
         thereof to subscribe for or purchase shares of Common Stock (either
         initially or under certain circumstances), which rights or warrants (i)
         are deemed to be transferred with such shares of Common Stock, (ii) are
         not exercisable and (iii) are also issued in respect of future
         issuances of Common Stock, in each case in clauses (i) through (iii)
         until the occurrence of a specified event or events ("Trigger Event"),
         shall for purposes of this Section 7(d)(vii) not be deemed issued until
         the occurrence of the earliest Trigger Event.

                                    (viii) In case a tender or exchange offer or
         other purchase made by the Company or any subsidiary of the Company for
         all or any portion of the Common Stock shall be consummated and such
         tender or exchange offer or purchase shall involve an aggregate
         consideration having a fair market value (as determined by the Board of
         Directors, whose determination shall, if made in good faith, be
         conclusive) as of the last time (the "Expiration Time") that tenders or
         exchanges may be made pursuant to such tender or exchange offer (as it
         shall have been amended) or the date of such other purchase, as the
         case may be, that, together with (A) the aggregate amount of the cash
         plus the fair market value (as determined by the Board of Directors,
         whose determination shall, if made in good faith, be conclusive) as of
         the Expiration Time of any other consideration paid in respect of any
         other tender or exchange offer or other purchase by the Company or a
         subsidiary of the Company for all or any portion of the Common Stock
         consummated within 12 months preceding the Expiration Time and in
         respect of which no Conversion Price adjustment has been made
         previously and (B) the aggregate amount of any distributions to all
         holders of the Common Stock made exclusively in cash within the 12
         months preceding the Expiration Time and in respect of which no
         Conversion Price adjustment has been made previously, exceeds 5.0% of
         the product of the Current Market Price per share of Common Stock
         immediately prior to the Expiration Time times the number of shares of
         Common Stock outstanding (including any tendered, exchanged or
         purchased shares) at the Expiration Time, then in each such case the
         Conversion Price shall be reduced (but not increased) so that it shall
         equal the price obtained by multiplying the Conversion Price in effect
         immediately prior to the Expiration Time by a fraction of which the
         numerator shall be (x) the product of the Current Market Price per
         share of Common Stock immediately prior to the Expiration Time,
         multiplied by the number of shares of Common Stock outstanding
         (including any tendered, exchanged or purchased shares) at the
         Expiration Time less (y) the sum of (i) the aggregate amount of cash
         plus the fair market value (determined as aforesaid) of any other
         consideration payable in respect of such tender or exchange offer or
         other purchase, (ii) the aggregate amount of any distributions to
         holders of Common Stock made exclusively in cash within the preceding
         12 months, in respect of which no Conversion Price adjustment has been
         made previously, and (iii) the aggregate amount of any cash plus the
         fair market value (determined as aforesaid) of any other consideration
         payable in respect to any other 




                                      -14-
<PAGE>   15

         tender or exchange offer or other purchase by the Company or a
         subsidiary of the Company for all or any portion of the Common Stock
         within the preceding 12 months, in respect of which no Conversion Price
         adjustment has been made previously; and the denominator shall be the
         product of such Current Market Price, multiplied by the number of
         shares of Common Stock outstanding (excluding any tendered, exchanged
         or purchased shares) at the Expiration Time. Such reduction shall
         become effective immediately prior to the opening of business on the
         date following the Expiration Time; provided, however, that if the
         number of tendered, exchanged or purchased shares or the aggregate
         consideration payable therefor has not been finally determined by such
         opening of business, the adjustment required by this subparagraph
         (viii) shall be made based upon the number of tendered, exchanged or
         purchased shares and the aggregate consideration payable therefor as so
         finally determined.

                                    (ix) No adjustment in the Conversion Price
         shall be required unless such adjustment would require an increase or
         decrease of at least 1% in such price; provided, however, that any
         adjustments which by reason of this subparagraph (ix) are not required
         to be made shall be carried forward and taken into account in any
         subsequent adjustment; and provided, further, that any adjustment
         required in order to preserve the tax-free nature of a distribution to
         the holders of shares of Common Stock shall be made when so required.
         All calculations under this Section 7 shall be made to the nearest cent
         (with $.005 being rounded upward). Anything in this Section 7(d) to the
         contrary notwithstanding, the Company shall be entitled, to the extent
         permitted by law, to make such reductions in the Conversion Price, in
         addition to those required by this Section 7(d), as it in its
         discretion shall determine to be advisable in order that any stock
         dividends, subdivision or combination of shares, distribution of
         capital stock or rights or warrants to purchase stock or securities,
         distribution of evidences of indebtedness or assets or any other
         transaction which could be treated as any of the foregoing transactions
         pursuant to Section 305 of the Internal Revenue Code of 1986, as
         amended (and any successor provision), hereafter made by the Company to
         its shareholders shall not be taxable to such shareholders.

                           (e) Subject to the provisions of Section 8, in case
the Company shall be a party to any transaction (including, without limitation,
a merger, consolidation, sale of all or substantially all of the Company's
assets, or recapitalization of the Common Stock and excluding any transaction as
to which paragraph (d)(iii), (vi) or (vii) of this Section 7 applies) (each of
the foregoing being referred to as a "Transaction"), in each case as a result of
which shares of Common Stock shall be converted into the right to receive stock,
securities or other property (including cash or any combination thereof), then
each share of the Series I Preferred Stock will thereafter no longer be subject
to conversion into Common Stock pursuant to Section 7, but instead shall be
convertible into the kind and amount of shares of stock and other securities and
property receivable (including cash) upon the consummation of such Transaction
by a holder of that number of shares or fraction thereof of Common Stock into
which one share of Series I Preferred Stock was convertible immediately prior to
such Transaction. The Company shall not be a party to any Transaction unless the
terms of such Transaction are consistent with the provisions of this Section
7(e) and it shall not consent or agree to the occurrence of any 




                                      -15-
<PAGE>   16

Transaction until the Company has entered into an agreement with the successor
or purchasing entity, as the case may be, for the benefit of the holders of the
Series I Preferred Stock which will contain provisions enabling the holders of
the Series I Preferred Stock which remains outstanding after such Transaction to
convert into the kind and amount of stock, securities or other property
(including cash or any combination thereof) which such holder would have been
entitled to receive if such holder had held the Common Stock issuable upon
conversion of such Series I Preferred Stock immediately prior to such
Transaction. In the event that at any time, as a result of an adjustment made
pursuant to this Section 7, the Series I Preferred Stock shall become subject to
conversion into any securities other than shares of Common Stock, thereafter the
number of such other securities so issuable upon conversion of the shares of
Series I Preferred Stock shall be subject to adjustment from time to time in a
manner and on terms as nearly equivalent as practicable to the provisions with
respect to the shares of Series I Preferred Stock contained in this Section 7.
The provisions of this Section 7(e) shall similarly apply to successive
Transactions.

                           (f) If:

                           (i) the Company shall take any action which would
         require an adjustment in the Conversion Price pursuant to Section 7(d);
         or

                           (ii) the Company shall authorize the granting to the
         holders of its Common Stock generally of rights or warrants to
         subscribe for or purchase any shares of any class or any other rights
         or warrants; or

                           (iii) there shall be any reclassification or change
         of the Common Stock (other than a subdivision or combination of its
         outstanding Common Stock or a change in par value) or any
         consolidation, merger or statutory share exchange to which the Company
         is a party and for which approval of any shareholders of the Company is
         required, or the sale or transfer of all or substantially all of the
         assets of the Company or any Change in Control (each as defined in
         Section 8 below) or any Transaction; or

                           (iv) there shall be a voluntary or involuntary
         dissolution, liquidation or winding up of the Company; 

         then, except as provided otherwise in Section 8, the Company shall
         cause to be filed with the Transfer Agent (if different than the
         Company) and shall cause to be given to the holders of shares of the
         Series I Preferred Stock, as promptly as possible, but at least 30 days
         prior to the applicable date hereinafter specified, a notice stating
         (A) the date on which a record is to be taken for the purpose of such
         dividend, distribution or granting of rights or warrants, or, if a
         record is not to be taken, the date as of which the holders of Common
         Stock of record to be entitled to such dividend, distribution or rights
         or warrants are to be determined or (B) the date on which such
         reclassification, change, consolidation, merger, statutory share
         exchange, sale, Change in Control, transfer, dissolution, Transaction,
         liquidation or winding up is expected to become effective or occur, and
         the date as of which it is expected that holders of Common Stock of
         record shall be entitled to exchange their shares of Common Stock for
         securities or other property deliverable 



                                      -16-
<PAGE>   17

         upon such reclassification, change, consolidation, merger, statutory
         share exchange, sale, Change in Control, transfer, dissolution,
         liquidation or winding up. Failure to give such notice or any defect
         therein shall not affect the legality or validity of the proceedings
         described in this Section 7(f).

                           (g) Whenever the Conversion Price is adjusted as
herein provided, the Company shall promptly file with the Transfer Agent (if
different than the Company) or, if the Transfer Agent is the Company, shall
provide to all holders of Series I Preferred Stock an officer's certificate
signed by the President or a Vice President and the Chief Financial Officer or
the Treasurer setting forth a brief statement of the facts requiring such
adjustment and upon which such adjustments are based. Promptly after delivery of
such certificate, the Company shall prepare a notice of such adjustment of the
Conversion Price setting forth the adjusted Conversion Price, the facts
requiring such adjustment and upon which such adjustments are based, the
calculation of the Conversion Price adjustment and the date on which such
adjustment becomes effective and shall give such notice of such adjustment of
the Conversion Price to the holder of each share of Series I Preferred Stock.

                           (h) In any case in which Section 7(d) provides that
an adjustment shall become effective immediately after a record date for an
event and the date fixed for such adjustment pursuant to Section 7 occurs after
such record date but before the occurrence of such event, the Company may defer
until the actual occurrence of such event (i) issuing to the holder of any
shares of Series I Preferred Stock converted after such record date and before
the occurrence of such event the additional shares of Common Stock issuable upon
such conversion by reason of the adjustment required by such event over and
above the Common Stock issuable upon such conversion before giving effect to
such adjustment and (ii) paying to such holder any amount in cash in lieu of any
fraction pursuant to Section 7(c).

                           (i) For purposes of this Section 7, the number of
shares of Common Stock at any time outstanding shall not include any shares of
Common Stock then owned or held by or for the account of the Company or any
corporation controlled by the Company.

                           (j) Notwithstanding any other provision herein to the
contrary, the issuance of any shares of Common Stock pursuant to any plan
providing for the reinvestment of dividends or interest payable on securities of
the Company and the investment of additional optional amounts of shares of
Common Stock under any such plan shall not be deemed to constitute an issuance
of Common Stock. In case of the issuance of any stock of the Company in a
reorganization, acquisition or other similar transaction which would require
adjustment of the Conversion Price pursuant to more than one paragraph of this
Section 7, only one adjustment shall be made and such adjustment shall be the
amount of adjustment which has the highest absolute value to the holders of
Series I Preferred Stock.

                           (k) The Board of Directors may in its discretion,
decrease the Conversion Price to the extent permitted by law, in such manner, if
any, and at such time, as the Board of Directors determines to be equitable in
the circumstances; provided, however, that in no event shall the Board of
Directors be required to take any such action.





                                      -17-

                           (l) The Company shall at all times reserve and keep
available, free from preemptive rights, out of its authorized but unissued
shares of Common Stock, sufficient shares of Common Stock to provide for the
conversion of the Series I Preferred Stock from time to time as such Series I
Preferred Stock is presented for conversion. For purposes of this Section 7(l),
the number of shares of Common Stock which shall be deliverable upon the
conversion of all outstanding shares of Series I Preferred Stock shall be
computed as if at the time of computation all such outstanding shares were held
by a single holder.

                           Before taking any action which would cause an
adjustment reducing the Conversion Price below the then par value of the shares
of Common Stock deliverable upon conversion of the Series I Preferred Stock, the
Company will take any corporate action which may, in the opinion of its counsel,
be necessary in order that the Company may validly and legally issue fully paid
and nonassessable shares of Common Stock at such adjusted Conversion Price.

                           The Company will, pursuant to the Registration Rights
Agreement relating to the Series I Preferred Stock, list the shares of Common
Stock required to be delivered upon conversion of the Series I Preferred Stock,
prior to delivery, upon each national securities exchange, the NASDAQ National
Market or any similar system of automated dissemination of securities prices, if
any, upon which the Common Stock is listed at the time of delivery.

                           Prior to the delivery of any securities which the
Company shall be obligated to deliver upon conversion of the Series I Preferred
Stock, the Company will use its best efforts to comply with all federal and
state laws and regulations thereunder requiring the registration of such
securities with, or any approval of or consent to the delivery thereof by, any
governmental authority.

                           (m) The Company will pay any and all documentary
stamp or similar issue or transfer taxes payable in respect of the issue or
delivery of the shares of Series I Preferred Stock (or any other securities
issued on account of the Series I Preferred Stock pursuant hereto) or shares of
Common Stock issued upon conversion of the Series I Preferred Stock pursuant
hereto; provided, however, that the Company shall not be required to pay any tax
which may be payable in respect of any transfer involved in the issue or
delivery of shares of Series I Preferred Stock pursuant hereto or shares of
Common Stock in a name other than the name in which the shares of Series I
Preferred Stock with respect to which such shares of Common Stock are issued
were registered and the Company shall not be required to make any issue or
delivery unless and until the person requesting such issue or delivery has paid
to the Company the amount of any such tax or has established, to the reasonable
satisfaction of the Company, that such tax has been paid or is not required to
be paid.

                  8. SPECIAL CONVERSION RIGHTS UPON CHANGE IN CONTROL.

                           (a) If a Change in Control (as defined below) should
occur with respect to the Company, each holder of shares of the Series I
Preferred Stock shall have the right, at the holder's option, for a period of 45
days after the giving of notice by the Company that a Change in Control has
occurred, to convert all, but not less than all, of such holder's shares of the




                                      -18-
<PAGE>   19

Series I Preferred Stock into the kind and amount of cash, securities, property
or other assets receivable upon such Change in Control by a holder of the number
of shares of Common Stock into which such holder's Series I Preferred Stock
would have been convertible immediately prior to the Change in Control at an
adjusted conversion price equal to the Special Conversion Price (as defined
below). Shares of the Series I Preferred Stock that are not converted as
provided above will remain convertible into the kind and amount of cash,
securities, property or other assets that the holders of the shares of the
Series I Preferred Stock would have owned immediately after the Change in
Control if the holders had converted the shares of the Series I Preferred Stock
immediately before the effective date of the Change in Control. The Company will
notify the holders of the Series I Preferred Stock of any pending Change in
Control as soon as practicable and in any event at least 30 days in advance of
the effective date of such Change in Control. In the event of a pending Change
in Control, the Company (or any successor corporation) shall take all action
necessary to provide for sufficient amounts of cash, securities, property or
other assets for the conversion of the Series I Preferred Stock as provided
herein.

                           (b) If a Change in Control shall occur, then, as soon
as practicable and in any event within five (5) business days after the
occurrence of such Change in Control, the Company shall provide notice to each
registered holder of a share of Series I Preferred Stock a notice (the "Special
Conversion Notice") setting forth details regarding the Special Right of the
holders to convert their shares of Series I Preferred Stock as a result of such
Change in Control. A holder of a share of Series I Preferred Stock must exercise
such conversion right within the 45-day period after the giving of the Special
Conversion Notice by the Company or such Special Right shall expire. The
conversion date for shares so converted shall be the 45th day after the giving
of the Special Conversion Notice or, if the merger, consolidation,
reorganization, liquidation or dissolution related to such Change in Control has
not become effective within 45 days of the giving of the Special Conversion
Notice but becomes effective within 90 days after the giving of the Special
Conversion Notice, then on the date of such effectiveness. If such merger,
consolidation, reorganization, liquidation or dissolution shall not occur within
90 days after the date on which the Special Conversion Notice is given, the
Company shall be required to give a new Special Conversion Notice. Within five
Business Days following the conversion date, the Company shall deliver a
certificate for the Common Stock together with a check for any fractional shares
issuable or the cash, securities, property or other assets receivable by a
holder. Exercise of such conversion right to the extent permitted by law
(including, if applicable, Rule 13d-3 under the Securities Exchange Act of 1934,
as amended (the "Exchange Act") shall be irrevocable and no dividends on the
shares of Series I Preferred Stock tendered for conversion shall accrue from and
after the conversion date.

                           (c) The Special Conversion Notice shall state:

                                    (i) The event constituting the Change in
         Control;

                                    (ii) the last date upon which holders may
         submit shares of Series I Preferred Stock for conversion at the Special
         Conversion Price;

                                    (iii) the Special Conversion Price;





                                      -20-
<PAGE>   20

                                    (iv) the Conversion Price then in effect
         under Section 7 and the continuing conversion rights, if any, under
         Section 7;

                                    (v) the name and address of any paying agent
         and conversion agent;

                                    (vi) that holders who wish to convert shares
         of Series I Preferred Stock must satisfy the requirements of Section 7
         and must exercise such conversion right within the 45-day period after
         giving of such notice by the Company;

                                    (vii) that exercise of such conversion right
         shall be irrevocable and no dividends on shares of Series I Preferred
         Stock tendered for conversion shall accrue from and after the
         conversion date; and

                                    (viii) that the consideration to be received
         shall be delivered within the five Business Days after the last date
         upon which holders may submit Series I Preferred Stock for conversion.

                           (d) (i) As used herein, a "Change in Control" with
respect to the Company means (A) the acquisition by a person, entity or "group,"
within the meaning of Section 13(d)(3) of the Exchange Act, (excluding, for this
purpose, the Company or any of its subsidiaries and any of Thomas Russell, The
AER Trust 1997, Robert Louis-Dreyfus, Gallium Enterprises, Inc. and Reuben
Richards which acquires beneficial ownership of voting securities of the
Company) of securities of the Company that result in such person, entity or
group having beneficial ownership (within the meaning of Rule 13d-3 promulgated
under the Exchange Act) of (x) 50% or more of either the then outstanding shares
of Common Stock or the combined voting power of the Company's then outstanding
voting securities entitled to vote generally in the election of directors or (y)
35% or more of either the then outstanding shares of Common Stock or the
combined voting power of the Company's then outstanding voting securities
entitled to vote generally in the election of directors, unless Thomas Russell,
The AER Trust 1997, Robert Louis-Dreyfus, Gallium Enterpises, Inc. and Reuben
Richards collectively beneficially own a greater percentage than such person,
entity or "group"; (B) approval by the shareholders of the Company of a
reorganization, merger or consolidation, in each case, with respect to which
persons who were the shareholders of the Company immediately prior to such
reorganization, merger or consolidation do not, immediately thereafter, own more
than 50% of the combined voting power entitled to vote generally in the election
of directors of the reorganized, merged or consolidated company's then
outstanding voting securities (a "Control Transaction"); or (C) approval of the
Board of Directors and, if required, of the shareholders of the Company of a
liquidation or dissolution of the Company (other than pursuant to the United
States Bankruptcy Code) or the sale of all or substantially all of the assets of
the Company.

                                    (ii) As used herein, a person shall be
         deemed to have "beneficial ownership" with respect to, and shall be
         deemed to "beneficially own," any securities of the Company in
         accordance with the definitions of such terms in Section 13 of the
         Exchange Act and rules and regulations (including Rule 13d-3, Rule
         13d-5, and any successor rules) promulgated by the Securities and
         Exchange Commission 




                                      -20-
<PAGE>   21

         thereunder; PROVIDED, HOWEVER, that a person shall be deemed to have
         beneficial ownership of all securities that any such person has a right
         to acquire whether such right is exercisable immediately or only after
         the passage of time and without regard to the 60-day limitation
         referred to in Rule 13d-3.

                                    (iii) As used herein, the "Market Value" of
         a share of the Common Stock shall be the average of the Closing Prices
         of the Common Stock for the five Trading Dates ending on the last
         Trading Day preceding the date of the Change in Control provided that,
         in the event the Change in Control was not announced at least ten (10)
         Trading Dates prior to its occurrence, then five Trading Dates ending
         ten (10) Trading Dates after a public announcement of such Change in
         Control.

                                    (iv) As used herein, the "Special Conversion
         Price" shall mean the lower of the Market Value of the Common Stock or
         $14.00 per share (which amount will, each time the Conversion Price is
         adjusted, be likewise adjusted).

                  9. REPURCHASE AT OPTION OF HOLDERS UPON CHANGE IN CONTROL.

                           (a) Upon the occurrence of a Change in Control (as
         defined in Section 8(d)) each holder of Series I Preferred Stock shall
         have the right (the "Repurchase Right") to require the Company to
         repurchase all of such holder's Series I Preferred Stock, or any
         portion thereof which is 100 shares or any integral multiple thereof at
         a price equal to 101% of the liquidation preference of the Series I
         Preferred Stock, plus accrued and unpaid dividends, if any, to the
         Repurchase Date. Such repurchase shall occur on the date (the
         "Repurchase Date") that is 45 days after the date of the Company Notice
         (as defined below). The Company will give a notice containing the
         information set forth in Section 9(b) below (the "Company Notice") to
         all holders within five (5) business days following any Change in
         Control, and the Company will purchase all tendered shares of Series I
         Preferred Stock by making payment of 101% of the liquidation preference
         plus accrued and unpaid dividends, if any, on the Repurchase Date. The
         Company shall promptly deliver a copy of the Company Notice to the
         Transfer Agent and shall cause a copy of such notice to be published in
         the Wall Street Journal or another newspaper of national circulation.
         The Company intends not to treat for tax purposes the Preferred Stock
         as having a redemption premium which is required to be treated as
         distributed pursuant to Section 305(c) of the Internal Revenue code.

                           (b) The Company Notice shall state

                                    (i) that a Change in Control has occurred
         and that each holder has the right to require the Company to repurchase
         such holder's shares of Series I Preferred Stock for cash at a price
         equal to 101% of the liquidation preference of the Series I Preferred
         Stock, plus accrued and unpaid dividends, if any, to the Repurchase
         Date and the amount of such repurchase price;

                                    (ii) the circumstances and relevant facts
         regarding the Change in Control;





                                      -21-
<PAGE>   22

                                    (iii) the Repurchase Date and the
         instructions a holder must follow in order to have such holder's
         securities repurchased in accordance with this Section 9.

                                    (iv) that any shares of Series I Preferred
         Stock not tendered will continue to accrue dividends.

                                    (v) that on the Repurchase Date any share of
         Series I Preferred Stock tendered for payment pursuant to the terms
         hereof and for which money sufficient to repurchase the shares of
         Series I Preferred Stock has been deposited by the Company as required
         by Section 9(c) hereof, shall cease to accrue dividends after the
         Repurchase Date;

                                    (vi) that holders electing to have shares of
         Series I Preferred Stock repurchased pursuant to this Section 9 will be
         required to surrender such shares, duly endorsed for transfer, together
         with irrevocable notice of such holder's intent to exercise such
         Repurchase Right, to the Company at the address specified in the
         Company Notice on or prior to the close of business on the 35th day
         after the date the Company's Notice is given; and

                                    (vii) such other information as may be
         required by applicable law or regulations;

PROVIDED that no failure of the Company to give the foregoing notices and no
defect therein shall limit the holder's Repurchase Right or affect the validity
of the proceedings for the repurchase of the shares of Series I Preferred Stock
pursuant to this Section 9.

                           (c) Following a Change in Control, the Company shall
accept for payment shares of Series I Preferred Stock properly tendered pursuant
to this Section 9. Prior to the Repurchase Date, the Company shall deposit with
a bank or trust company having a capital and surplus of at least $50,000,000,
funds sufficient to pay the redemption price for all shares of Series I
Preferred Stock tendered and shall deliver, or cause to be delivered to such
bank or trust company, the shares of Series I Preferred Stock properly tendered
pursuant to this Section 9 and accepted together with an officer's certificate
describing the shares of Series I Preferred Stock so tendered to and being
purchased by the Company. On the Repurchase Date, the bank or trust company
shall, to the extent that monies deposited with such bank or trust company are
available therefor, give to the holders of shares of Series I Preferred Stock so
tendered and accepted payment in an amount equal to the redemption price and, as
soon as possible after such payment, the bank or trust company shall cancel the
shares of Series I Preferred Stock so tendered and accepted. The Company will
publicly announce the results of the Change in Control tender offer as soon as
practicable after the Repurchase Date. The Company will issue to holders whose
shares of Series I Preferred Stock are purchased only in part new shares of
Series I Preferred Stock equal in principal amount to the unpurchased portion of
the shares of Series I Preferred Stock surrendered.

                           (d) Notwithstanding the foregoing, in repurchasing
the shares of Series I Preferred Stock pursuant to this Section 9, the Company
will comply with all applicable tender offer rules, including but not limited to
Sections 13(e) and 14(e) under the Exchange Act and Rules 13c-1 and 14c-1
thereunder.

                  10. RANKING. Any class or classes of stock of the Company
shall be deemed to rank:

                                    (i) prior to the Series I Preferred Stock,
         as to dividends or as to the distribution of assets upon liquidation,
         dissolution or winding up, if the holders of such class shall be
         entitled to the receipt of dividends or of amounts distributable upon
         liquidation, dissolution winding up, as the case may be, in preference
         or priority to the holders of Series I Preferred Stock.

                                    (ii) on a parity with the Series I Preferred
         Stock, as to dividends or as to the distribution of assets upon
         liquidation, dissolution or winding up, whether or not the dividend
         rates, dividend payment dates or redemption or liquidation prices per
         share thereof be different from those of the Series I Preferred Stock,
         if the holders of such class of stock and the Series I Preferred Stock
         shall be entitled to the receipt of dividends or of amounts
         distributable upon liquidation, dissolution or winding up, as the case
         may be, in proportion to their respective amount of accrued and unpaid
         dividends per share or liquidation prices, without preference or
         priority of one over the other, and

                                    (iii) junior to the Series I Preferred
         Stock, as to dividends or as to the distribution of assets upon
         liquidation, dissolution or winding up, if such stock shall be Common
         Stock or if the holders of Series I Preferred Stock shall be entitled
         to receipt of dividends or of amounts distributable upon liquidation,
         dissolution or winding up, as the case may be, in preference or
         priority to the holders of shares of such stock.

                  11. VOTING.

                           (a)(i) Except as herein provided or as otherwise from
time to time required by law, holders of Series I Preferred Stock shall have one
vote per share of Common Stock issuable upon conversion thereof on all matters
submitted to the holders of the Common Stock, and shall vote with the Common
Stock as a single class. Whenever, at any time or times, dividends payable on
the shares of Series I Preferred Stock shall be cumulatively in arrears in an
amount equal to or greater than the amount payable in respect of six complete
Dividend Periods; the holders of Series I Preferred Stock shall have the
exclusive right, voting separately as a class to elect two directors of the
Company at the Company's next annual meeting of shareholders and at each
subsequent annual meeting of shareholders until such dividends have been paid.
If such voting rights shall become vested more than 90 days or less than 20 days
before the date prescribed for the annual meeting of shareholders, thereupon the
holders of the shares of Series I Preferred Stock shall be entitled to exercise
their voting rights at a special meeting of the holders of Series I Preferred
Stock as set forth in paragraphs (ii) and (iii) of this Section 11(a). At
elections for such directors, each holder of Series I Preferred Stock shall be
entitled to one vote 




                                      -23-
<PAGE>   24

for each share held by such holder. Upon the vesting of such right of the
holders of the Series I Preferred Stock, the maximum authorized number of
members of the Board of Directors shall automatically be increased by two, the
size of the Board of Directors shall automatically be increased by two directors
and the two vacancies so created shall be filled by vote of the holders of
outstanding Series I Preferred Stock as hereinabove set forth. The right of
holders of the Series I Preferred Stock, voting separately as a class, to elect
members of the Board of Directors as aforesaid shall continue until such time as
all dividends accumulated on the Series I Preferred Stock shall have been paid,
or declared and funds or additional shares of Series I Preferred Stock set aside
for payment in full, at which time such right shall terminate, except as herein
or by law expressly provided, subject to revesting in the event of each and
every such subsequent default. Notwithstanding the foregoing, in the event the
holders of Preferred Stock are entitled to elect a director as provided in
Section 11(b), the number of directors which the holders of the Series I
Preferred Stock may elect pursuant to this Section 11(a) shall be one, and the
number of directors which the holders of the Series I Preferred Stock may elect
pursuant to Section 11(b) shall be one.

                                    (ii) Whenever such voting right shall have
         vested, such right may be exercised initially either, as provided in
         Section 11(a)(i) or 11(b), at a special meeting of the holders of
         shares of the Series I Preferred Stock called as hereinafter provided,
         or at any annual meeting of shareholders held for the purposes of
         electing directors, and thereafter at such meetings or by the written
         consent of such holders pursuant to the Business Corporation Act of the
         State of New Jersey.

                                    (iii) At any time when such voting rights
         shall have vested in the holders of shares of the Series I Preferred
         Stock and if such right shall not already have been initially
         exercised, an officer of the Company shall, upon the written request of
         holders of record of 10% or more of shares of the Series I Preferred
         Stock then outstanding, addressed to the Chief Financial Officer of the
         Company, call a special meeting of holders of shares of the Series I
         Preferred Stock. Such meeting shall be held at the earliest practicable
         date upon the notice required for annual meetings of shareholders at
         the place for holding annual meetings of shareholders of the Company
         or, if none, at a place designated by the Chief Financial Officer of
         the Company. If such meeting shall not be called by the proper officers
         of the Company within 30 days after the personal service of such
         written request upon the Chief Financial Officer of the Company, or
         within 30 days after giving notice, then the holders of record of 10%
         of the shares of the Series I Preferred Stock then outstanding may
         designate in writing any person to call such meeting at the expense of
         the Company, and such meeting may be called by such person so
         designated upon the notice required for annual meetings of shareholders
         and shall be held at the location requested by the person calling the
         meeting. Any holder of shares of the Series I Preferred Stock then
         outstanding that would be entitled to vote at such meeting shall have
         access to the stock record books of the Company for the purpose of
         causing a meeting of shareholders to be called pursuant to the
         provisions of this paragraph. Notwithstanding the provisions of this
         paragraph, however, no such special meeting shall be called or held
         during a period within 45 days immediately preceding the date fixed for
         the next annual meeting of shareholders.

                                    (iv) The directors elected pursuant to this
         Section 11(a) shall serve until the earlier of (A) the next annual
         meeting or until their respective successors shall be elected and shall
         qualify or (B) the date that the Company has paid all accrued and
         unpaid dividends on the Series I Preferred Stock. Any director elected
         by the holders of Series I Preferred Stock may be removed by, and shall
         not be removed otherwise than by, the vote of the holders of a majority
         of the outstanding shares of the Series I Preferred Stock, as
         applicable, voting as a separate class, at a meeting called for such
         purpose or by written consent as permitted by law and the Certificate
         of Incorporation and By-laws of the Company; provided, that upon
         payment of all accrued, but unpaid dividends, such person shall
         automatically and without further action cease to be members of the
         Company's Board of Directors. If the office of any director elected by
         the holders of the Series I Preferred Stock, as applicable, voting as a
         class, becomes vacant by reason of death, resignation, retirement,
         disqualification or removal from office or otherwise, the remaining
         director elected by the holders of the Series I Preferred Stock may
         choose a successor who shall hold office for the unexpired term in
         respect of which such vacancy occurred. Upon any termination of the
         right of the holders of the Series I Preferred Stock to vote for
         directors as herein provided, the term of office of all directors then
         in office elected by the holders of the Series I Preferred Stock shall
         terminate immediately. Whenever the terms of office of the directors
         elected by the holders of the Series I Preferred Stock shall so
         terminate and the special voting powers vested in the holders of the
         Series I Preferred Stock shall have expired, the number of directors
         shall be such number as may be provided for pursuant to the By-laws of
         the Company irrespective of any increase made pursuant to the
         provisions of this Section 11.

                           (b) Until such time as there are outstanding a number
of shares of Series I Preferred Stock less than that number of shares equal to
two-thirds of the number of shares of Series I Preferred Stock issued in
November 1998 to Hakuto Co., Ltd., Union Miniere, Inc. and Uniroyal Technology
Corporation (as adjusted for any stock combinations or splits with respect to
such shares) (the "Threshold Amount"), if the Company materially breaches a
substantive provision of one of the Strategic Agreements (as defined below), the
holders of Series I Preferred Stock who are a party to one or more of the
Strategic Agreements that have been breached by the Company shall collectively
have the right, voting separately as a class, to elect one director of the
Company at the Company's next annual meeting of the shareholders; provided,
however, that if such voting rights shall become vested more than 90 days or
less than 20 days before the date of the prescribed annual meeting of
shareholders, such holders of the shares of Series I Preferred Stock shall be
entitled to exercise their voting rights at a special meeting of the holders of
the shares of Series I Preferred Stock as set forth in Sections 11(a)(ii) and
(iii). At such elections for directors, each such holder of Series I Preferred
Stock shall be entitled to one vote for each share held. Upon the vesting of
such right of the holders of Series I Preferred Stock, the maximum authorized
number of members of the Board shall automatically be increased by one, the size
of the Board of Directors shall automatically be increased by one director and
the one vacancy so created shall be filled by vote of the holders of Series I
Preferred Stock as hereinabove set forth. The right of holders of Series I
Preferred Stock, voting separately as a class, to elect a member of the Board of
Directors pursuant to this Section 11(b) shall continue until the earlier of (i)
the cure of each material breach giving rise such right or (ii) the 




                                      -25-
<PAGE>   26

date that less than the Threshold Amount of shares of Series I Preferred Stock
is outstanding. As used herein the term "Strategic Agreements" shall mean the
following agreements as each may be amended and any material agreements related
thereto: distributorship agreements with Hakuto Co., Ltd.; the Joint-Venture
Agreement between the Company and Union Miniere Inc., the Limited Liability
Company Agreement of Umcore LLC, the Management and Services Agreement between
Umcore LLC and the Company, the Party IP License Agreement between the Company
and Umcore LLC, the New Application License Agreement between the Company and
Umcore LLC, the Amended and Restated Joint Venture Agreement, dated November
1998 among the Company, Uniroyal Technology Corporation and Uniroyal
Optoelectronics, Inc. and the Amended and Restated Technology License Agreement,
dated November 1998 among the Company, Uniroyal Technology Corporation and
Uniroyal Optoelectronics, Inc.

                           (c) So long as any shares of the Series I Preferred
Stock remain outstanding, the consent of the holders of at least two-thirds of
the shares of Series I Preferred Stock outstanding at the time, given in person
or by proxy either in writing (as permitted by law and the Certificate of
Incorporation and By-laws of the Company) or at any special or annual meeting,
shall be necessary to permit, effect or validate any one or more of the
following:

                                    (i) the authorization, creation or issuance,
         or any increase in the authorized or issued amount of any class or
         series of stock, or any security convertible into stock of such class
         or series, ranking prior to or on parity with the Series I Preferred
         Stock (including the authorization or issuance of additional shares of
         Series I Preferred Stock other than issuances of Series I Preferred
         Stock as a dividend on any then outstanding shares of Series I
         Preferred Stock) as to dividends or the distribution of assets upon
         liquidation, dissolution or winding up;

                                    (ii) the amendment, alteration or repeal,
         whether by merger, consolidation or otherwise, of any of the provisions
         of the Certificate of Incorporation (including this Certificate) or the
         Bylaws of the Company which would adversely affect any right,
         preference, privilege or voting power of the Series I Preferred Stock
         or of the holders thereof; provided, however, that the creation and
         issuance of other series of preferred stock, or any increase in the
         amount of authorized shares of such series or of any other series of
         preferred stock, in each case ranking junior to the Series I Preferred
         Stock with respect to the payment of dividends and the distribution of
         assets upon liquidation, dissolution or winding up, shall not be deemed
         to adversely affect such rights, preferences, privileges or voting
         powers; or

                                    (iii) the authorization of any
         reclassification of the Series I Preferred Stock.

                           The unanimous consent of the Series I Preferred Stock
is required to modify or eliminate the mandatory redemption provisions in
Section 5(b) hereof. The foregoing voting provisions shall not apply if, at or
prior to the time when the act with respect to which such vote would otherwise
be required shall be effected, all outstanding shares of Series I 




                                      -26-
<PAGE>   27

Preferred Stock shall have been redeemed or sufficient funds shall have been
deposited in trust to effect such redemption, scheduled to be consummated within
three months after such time.

                  12. PREEMPTIVE RIGHTS. Subject to Section 12(d), for so long
as at least the Threshold Amount of shares of Series I Preferred Stock is
outstanding, each time the Company proposes to sell shares of its capital stock
or options, warrants or other rights to buy capital stock for cash, the Company
shall also make an offering of such securities to the holders of Series I
Preferred Stock in accordance with the following provisions:

                           (a) The Company shall deliver a notice to each holder
of Series I Preferred Stock stating the number of securities to be offered and
the price and the terms on which it proposes to offer such securities. Such
notice shall be sent to the addresses set forth in the records of the Company.

                           (b) Each holder of Series I Preferred Stock may elect
to purchase, at the price and on the terms specified in the notice, up to its
Pro Rata Portion of such securities by delivering written notice of such
election to the Company within 14 calendar days of the giving of such notice.
Such election to purchase shall state that it is a binding commitment to
purchase the securities. "Pro Rata Portion" shall mean the number of securities
determined by multiplying the number of securities subject to the notice in
Section 12(a) above by a fraction the numerator of which is the number of shares
of Series I Preferred Stock held by such holder and the denominator of which is
the number of shares of Series I Preferred Stock held by all holders provided,
however, that if any of the holders of Series I Preferred Stock shall not elect
to purchase their full Pro Rata Portion, the Pro Rata Portion of each holder
electing to purchase its full Pro Rata Portion (without giving effect to this
oversubscription adjustment) shall be increased by a proportionate amount of
such unsubscribed shares.

                           (c) Any shares referred to in the notice that are not
elected to be purchased as provided in subsection (b) above may, during the
180-day period thereafter, be offered by the Company to any other person or
persons at a price not less than, and on terms not materially more favorable to
the offeree than, those specified in the notice.

                           (d) The preemptive rights set forth in this Section
12 shall not be applicable to the issuance of (i) securities to directors,
officers, or employees of the Company as a form of compensation or in connection
with their initial employment, (ii) shares of common stock issuable upon
exercise of any options or warrants, (iii) capital stock in connection with a
merger, acquisition, plan of exchange or consolidation of another company, (iv)
capital stock in connection with a joint venture, (v) securities pursuant to a
registration statement filed pursuant to the Securities Act with the Securities
and Exchange Commission, (vi) Common Stock or other securities issued upon
conversion of the Series I Preferred Stock or (vii) Series I Preferred Stock
issued as a dividend on the Series I Preferred Stock.

                  13. RECORD HOLDERS. The Company and the Transfer Agent may
deem and treat the record holder of any shares of Series I Preferred Stock as
the true and lawful owner thereof for all purposes, and neither the Company nor
the Transfer Agent shall be affected by any notice to the contrary.

shall be deemed to have been given upon receipt, in the case of a notice of
conversion given to the Company as contemplated in Section 7(b) hereof, or, in

         1.       EXERCISE.

                  (a) Subject to the requirements of Section 5, this Warrant may

                           (i) a certificate or certificates for the number of
full Warrant Shares to which such Registered Holder shall be entitled upon such
exercise plus, in lieu of any fractional share to which such Registered Holder
would otherwise be entitled, cash in an amount determined pursuant to Section 4
hereof; and

                           (ii) in case such exercise is in part only, a new
warrant or warrants (dated the date hereof) of like tenor, calling in the
aggregate on the face or faces thereof for the number of Warrant Shares equal
(without giving effect to any adjustment therein) to the number of such shares
called for on the face or this Warrant minus the number of such shares purchased
by the Registered Holder upon such exercise as provided in subsection 1(a)
above.

                  2.       CALL PROVISION.

                  This Warrant may be called in whole or in part by the Board of
Directors of the Company upon 30 days written notice to the holder at any time
after October 1, 1998 at a price per warrant of $0.85. No call of this warrant
shall be made unless (i) the Corporation can deliver registered shares of Common
Stock and (ii) the price per share of Common Stock is at least 150% of the
Purchase Price for at least 30 consecutive trading days.

                  3.       ADJUSTMENTS.

                           (a) EFFECT OF STOCK CHANGES. If, at any time or from
time to time the Company, by stock dividend, stock split, subdivision, reverse
split, consolidation, reclassification 





<PAGE>   3

of shares, or other similar structural change, changes as a whole its
outstanding Common Stock into a different number or class of shares, then,
immediately upon the occurrence of the change:

                                    (i) the class of shares into which the
Common Stock has been changed shall replace the Common Stock, for the purposes
of this Warrant and the terms and conditions hereof, so that the registered
owner or owners of this Warrant shall be entitled to receive, and shall receive
upon exercise of this Warrant, shares of the class of stock into which the
Common Stock had been changed;

                                    (ii) the number of shares purchasable upon
exercise of this Warrant shall proportionately be adjusted. (For example, if the
outstanding Common Stock of the Corporation is converted into X stock at the
rate of one (1) share of Common Stock into three (3) shares of X stock, and
prior to the change the Registered Holder of this Warrant were entitled, upon
exercise of this Warrant, to purchase one hundred shares of Common Stock, then
the registered owner or owners shall, after the change, be entitled to purchase
three hundred shares of X stock for the total same exercise price that the owner
or owners had to pay prior to the change to purchase the one hundred shares of
Common Stock); and

                                    (iii) the purchase price per share shall be
proportionately adjusted. (In the above example, the purchase price per share
would be reduced by two-thirds).

         Irrespective of any adjustment or change in the number or class of
shares purchasable under this or any other Warrant of like tenor or in the
purchase price per share, this Warrant, as well as any other warrant of like
tenor, may continue to express the purchase price per share and the number and
class of shares purchasable upon exercise of this Warrant as the purchase price
per share and the number and class of shares purchasable were expressed in this
Warrant when it was initially issued.

                           (b) EFFECT OF MERGER. If at any time while this
Warrant is outstanding another corporation merges into the Company, the
Registered Holder of this Warrant shall be entitled, immediately after the
merger becomes effective and upon exercise of this Warrant, to obtain the same
number of shares of Common Stock of the Company (or shares into which the Common
Stock has been changed as provided in the paragraph of this Warrant covering
changes) to which the owner or owners were entitled upon the exercise hereof to
obtain immediately before the merger became effective at the same exercise
price. The Company shall take any and all steps necessary in connection with the
merger to assure that sufficient shares of Common Stock to satisfy all
conversion and purchase rights represented by outstanding convertible
securities, options and warrants, including this Warrant, are available so that
these convertible securities, options and warrants, including this Warrant, may
be exercised.

                           (c) EFFECT OF CONSOLIDATION OR SALE. Notwithstanding
any provision of this Warrant concerning the callability of this Warrant, if the
Company consolidates with or merges into another corporation or other entity in
a transaction in which the Company is not the surviving corporation, or receives
an offer to purchase or lease all or substantially all of the assets of the
Company or an offer to purchase forty-five percent (45%) or more of the issued
and outstanding Common Stock of the Company, or if all or substantially all of
the assets of the 





<PAGE>   4

Company are sold or leased or forty-five percent (45%) or more of the issued and
outstanding Common Stock of the Company is purchased by any person or group of
persons acting in concert, then this Warrant shall be called by the Company on
the Effective Date of such consolidation or merger or asset sale, or in the case
of an offer to purchase forty-five percent (45%) of the Company's Common Stock,
on the date such offer is accepted by the Company. The right to exercise this
Warrant shall terminate when it is called. The call price shall be determined by
the board of directors of the Company in accordance with the provisions of this
second and third sentences of paragraph 3 hereof as of the time the event
triggering the call occurs, or the value of the securities or the other
consideration that shall be received in the transaction by the owner of a number
of outstanding shares of Common Stock equal to the number of shares purchasable
upon exercise of this Warrant. This call price shall be payable not later than
sixty (60) days after the effective date of the call to the registered owner or
owners of this Warrant upon its surrender for cancellation at the offices of the
Company, together with the transfer or assignment form which forms a part
hereof, duly completed and executed in blank.

                           (d) DISSOLUTION. In the event that a voluntary or
involuntary dissolution, liquidation or winding up of the Company (other than in
connection with a merger where the Company is the surviving corporation as
covered in this Warrant, or a merger or consolidation with or into another
corporation, a sale or lease of all or substantially all of the assets of the
Company, or a sale of a specified portion or percentage of its stock as covered
in this Warrant) is at any time proposed during the term of this Warrant, the
Company shall give written notice to the registered owner or owners of this
Warrant at least thirty (30) days prior to the record date of the proposed
transaction. The notice must contain:

                                    (i) the date on which the transaction is to
take place;

                                    (ii) the record date (which must be at least
thirty (30) days after the giving of the notice) as of which holders of the
Common Stock entitled to receive distributions as a result of the transaction
shall be determined;

                                    (iii) a brief description of the
transaction;

                                    (iv) a brief description of the
distributions, if any, to be made to holders of the Common Stock as a result of
the transaction; and

                                    (v) an estimate of the fair market value of
the distributions.

On the date of the transaction, if it actually occurs, this Warrant and all
rights existing under this Warrant shall terminate.

         4. FRACTIONAL SHARES. The Company shall not be required upon the
exercise of this Warrant to issue any fractional shares, but shall pay in cash
an amount determined by multiplying the fraction to which the Holder is entitled
by the fair market value of the Common Stock on the date of exercise. Should the
Common Stock then be traded on an Exchange or quoted on a quotation system for
which a last sale reporting system is in effect, the reported last sale on the
exercise date shall be deemed to be such fair market value. If the Common Stock
is 





<PAGE>   5

quoted on a quotation system without last sale reporting, the fair market value
shall be deemed to be the highest bid price of any broker/dealer regularly
making a market in the Common Stock on the exercise date. In all other cases
fair market value shall be as determined in good faith by the Company.

         5.       CERTAIN REQUIREMENTS FOR TRANSFER AND EXERCISE.

                  (a) In the absence of an effective Registration Statement
under the Securities Act of 1933, as amended (the "Act"), it shall be a
condition to any transfer or any exercise of this Warrant that the Issuer shall
be received, at the time of such transfer or exercise:

                           (i) A representation in writing from the proposed
transferee that the Warrant is being transferred or the Common Stock being
purchased is being acquired for investment and not with a view to any sale or
distribution thereof which would constitute or result in a violation of the Act;

                           (ii) an opinion of counsel, which opinion is
reasonably satisfactory to the Issuer, that the transaction shall not result in
a violation of state or federal securities laws.

                  (b) In such case, each certificate representing the Warrant
and the Warrant Shares shall bear a legend substantially in the following form:

                  THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN

                  SECURITIES ACT, AS THE SAME MAY BE AMENDED FROM TIME TO TIME,
                  (4) IN RELIANCE ON ANOTHER EXEMPTION FROM THE REGISTRATION
                  REQUIREMENTS OF THE SECURITIES ACT, AND SUBJECT TO THE RECEIPT
                  BY THE COMPANY OF AN OPINION OF COUNSEL TO THE EFFECT THAT
                  SUCH TRANSFER DOES NOT REQUIRE REGISTRATION UNDER THE
                  SECURITIES ACT, OR (5) PURSUANT TO AN EFFECTIVE REGISTRATION
                  STATEMENT UNDER THE SECURITIES ACT, IN EACH CASE IN ACCORDANCE
                  WITH APPLICABLE SECURITIES LAWS OF ANY STATE OF THE UNITED
                  STATES.

("Contract Year"). Hakuto will submit to Emcore purchase orders during each of
the [*]. For each succeeding Contract Year of the Agreement, Hakuto and Emcore
shall mutually agree on a minimum purchase order amount for each such year prior
to commencement of such Contract Year. In computing the value of the minimum
purchase amount for each Contract Year, there shall be included the value of all
Equipment shipped during said Contract Year, the value of orders placed by
Hakuto though not shipped by Emcore during the Contract Year, and the value of
orders procured by Hakuto but canceled by Hakuto's customer by reason of
Emcore's inability to perfect delivery of the Equipment within six (6) months
from date of the order. The value of all of the foregoing orders which exceeds
the minimum purchase commitment for any Contract Year shall be credited to
Hakuto's minimum purchase order commitment for the subsequent Contract Year.

this Agreement and each twelve (12) month period thereafter during the term of

identifies all registered, recorded or issued material intellectual property,
including registered copyrights and trademarks, issued patents and applications

interest in

the Territory such as, inter alia, know-how and common law trademarks shall
hereafter be referred to as "Intellectual Property"). Hakuto is hereby granted a
license and privilege to use all of the Intellectual Property, including any
improvements, modifications or functional equivalents, during the term of this
Agreement in furtherance of the objectives of this Agreement. Hakuto shall not
have the right to sublicense (except to Hakuto's subsidiaries and affiliates)
the Intellectual Property or otherwise permit its use by third parties without
Emcore's prior written consent. If Hakuto is required by law to register its
licenses in Japan or, in its sole discretion, determines that registration
hereof should be effected in order to protect the rights and interests of Hakuto
hereunder, then Emcore shall cooperate with Hakuto to effect the same.

         10.2 HAKUTO COOPERATION. Hakuto shall advise Emcore from time to time
of any additional filings, registrations or other actions that may be necessary
or desirable for the protection of Emcore's Intellectual Property in the
Territory. Upon Emcore's request, Hakuto shall assist Emcore in connection with
the issuance or registration of any new Emcore patents, copyrights, trademarks
or other Intellectual Property in the Territory.

         10.3 INFRINGEMENT. Hakuto shall at all times respect and protect
Emcore's rights of total ownership of the Intellectual Property in the
Territory. Hakuto shall promptly notify Emcore of any infringements of such
rights of which Hakuto has notice and shall assist Emcore in taking such action
against such infringement as Emcore may elect.

         10.4 TERMINATION OF LICENSE. Upon termination of this Agreement for any
reason, Hakuto shall promptly relinquish to Emcore any rights to the use of the
Intellectual Property and shall thereafter refrain from using the same.

         10.5 INFRINGEMENT INDEMNIFICATION. If Hakuto or its customers are
served notice of alleged infringement of any patents, designs, copyrights and/or
trademarks arising from the sale or use of any of the Products, Emcore shall, at
its own expense and with diligence, defend and hold Hakuto and its customers
free and harmless from and against any and all claims, loss, damage, suits,
causes of action and/or liability (and against all associated costs and
expenses, including, without limitation, reasonable attorneys' fees and costs of
litigation) whenever and wherever they

may occur, on account of said alleged infringement; provided, however, that
Emcore shall have no obligation to indemnify Hakuto or its customers to the
extent the alleged infringement is due solely to: (a) a Product modification by
Hakuto or the customer; (b) use of a Product in combination with any other
device or thing; or (c) failure to use the Product in accordance with its
customary use or in conformity with Emcore's instructions and operating
guidelines. If Emcore shall fail or refuse to do so, Hakuto and its customers
may take such action as Hakuto or its customer, or jointly, may deem necessary,
and all costs, attorneys' fees, losses or damages as may be incurred by Hakuto
or its customers shall be the obligation of Emcore to be recovered by Hakuto or
its customers by suit or otherwise.

         10.6 QUALITY CONTROL. In connection with any use hereunder by Hakuto of
any registered or unregistered trademark owned by Emcore, Emcore shall have the
right at all times to: (a) establish and require Hakuto's adherence to quality
control standards governing the repair, sale and quality of the Products; and
(b) establish and require Hakuto's adherence to standards governing the manner
of display of any Emcore trademark in promotional, technical and informational
materials. Emcore shall have the right to request, at reasonable intervals,
inspection by Emcore or its designee of Hakuto's operations and of any materials
used or created by Hakuto displaying any Emcore trademark, so that Emcore can
verify to its satisfaction that the Products, services and display of trademarks
conform to the appropriate standard of quality.

11. CONFIDENTIALITY. Each party hereto when receiving information from the other
party (in such case, a "Receiving Party") agrees to use its best efforts to hold
in strict confidence and not to disclose to others or use, for a period of three
years after termination hereof, any technical or business information,
manufacturing technique, process, experimental work, trade secret or other
confidential matter relating to the business of the party in possession of such
information (such party, a "Disclosing Party") or relating to the Products, in
the case of Hakuto, or the other party's business ("Confidential Information"),
except to the extent necessary to further the objectives of this Agreement. This
SECTION 11 shall not apply to: (1) information known to the Receiving Party
prior to disclosure by the Disclosing Party of Confidential Information; (2)
Confidential Information which is, or becomes through no fault of the Receiving
Party, generally known or available to the public; (3) Confidential Information

Information which the Disclosing Party discloses to a third party who is not

termination of this Agreement without request), deliver to the Receiving Party
any and all drawings, notes, documents and materials received from the Receiving
Party.

12. ASSIGNMENT. Neither party shall assign, transfer or otherwise dispose of
this Agreement or any of its rights or obligations hereunder in whole or in part
to any individual, firm or corporation without the prior written consent of the

be null and void.

Attn:  Richard Laird


Dear Sirs:

                  EMCORE Corporation, a New Jersey corporation (the "Company"),
proposes to issue and sell to each of Hakuto Co., Ltd., Uniroyal Technology
Corporation and Union Miniere Inc. (each a "Purchaser" and collectively the
"Purchasers") the number of shares of its Series I Redeemable Convertible
Preferred Stock (the "Preferred Stock") listed on Exhibit A hereto. The
Preferred Stock will be convertible at the option of the holders thereof, unless
previously redeemed, into shares of common stock, no par value per share, of the
Company (the "Underlying Common Stock" and, together with the Preferred Stock,
the "Securities") at an initial conversion price of $14.00 per share of Common
Stock, subject to adjustment in certain events. The Preferred Stock is
redeemable, in whole or in part, at the option of the Company at any time if the
last reported sales price of the Company's common stock, no par value per share
(the "Common Stock") is $28.00 per share or greater for 30 consecutive trading
days, at a price of $14.00 per share, plus accrued and unpaid dividends, if any,
to the redemption date. Upon the occurrence of a Change in Control (as defined
below), the Company will be obligated either to offer to purchase all or any
part of each holder's Shares at a price equal to $14.14 per Share, plus accrued
and unpaid dividends, or to adjust the conversion price, as described herein.
The Shares of Preferred Stock are subject to mandatory redemption by the Company
on November 17, 2003.

                  The Securities will be offered without being registered under
the Securities Act of 1933, as amended (the "Securities Act"), in reliance on
exemptions therefrom. Resale of the Underlying Common Stock shall be registered
in the future pursuant to the terms of a 



<PAGE>   2

Registration Rights Agreement to be dated as of the date hereof (the
"Registration Rights Agreement") between the Company and the Purchasers.

                  In connection with the offer and sale of the Securities, the
Company has prepared a private placement memorandum (the "Memorandum") setting
forth or including a description of the Securities, the terms of the offering, a
description of the Company and any material developments relating to the Company
occurring after the date of the most recent financial statements included
therein. As used herein, the term "Memorandum" shall include in each case the
documents incorporated therein by reference.

                  1. REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The Company
represents and warrants to you, and agrees with you, that as of the date hereof
and as of the closing date:

                  (a) (i) Each document, if any, filed or to be filed pursuant
to the Exchange Act and incorporated by reference in the Memorandum has complied
or will comply when so filed in all material respects with the Exchange Act and
the applicable rules and regulations thereunder and (ii) the Memorandum does not
contain any untrue statement of a material fact or omit to state a material fact
necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading.

                  (b) The Company has been duly incorporated and is validly
existing as a corporation in good standing under the laws of the jurisdiction of
its incorporation, has the corporate power and authority to own its property and
to conduct its business as it is currently being conducted and as described in
the Memorandum and is duly qualified to transact business and is in good
standing in each jurisdiction in which the conduct of its business or its
ownership or leasing of property requires such qualification, except to the
extent that the failure to be so qualified or be in good standing would not have
a material adverse effect on the Company and its subsidiary, taken as a whole.

                  (c) The Company's only subsidiary is MicroOptical Devices,
Inc. Such subsidiary has been duly incorporated, is validly existing as a
corporation and is in good standing under the laws of the jurisdiction of its
incorporation, has the corporate power and authority to own its property and to
conduct its business as described in the Memorandum and is duly qualified to
transact business and is in good standing in each jurisdiction in which the
conduct of its business or its ownership or leasing of property requires such
qualification, except to the extent that the failure to be so qualified or be in
good standing would not have a material adverse effect on the Company and its
subsidiary, taken as a whole.

                  (d) The Preferred Stock has been duly authorized and, when
issued to and paid for by the Purchasers, will be validly issued, fully paid and
non-assessable and will not be subject to any preemptive rights or similar
rights. The Preferred Stock shall have the rights, preferences and privileges
and restrictions set forth in the form of Certificate of Amendment attached
hereto as Exhibit C (the "Certificate of Designation").

<PAGE>   3

                  (e) The Underlying Common Stock reserved for issuance upon
conversion of the Preferred Stock has been duly authorized and reserved and its
issuance in accordance with the Certificate of Designation has been approved,

issued, fully paid and non-assessable and will not be subject to any preemptive
rights or similar rights.

                  (f) Each of this Agreement, the Registration Rights Agreement,
the Certificate of Designation and any other agreement to which the Company is a
party contemplated hereby (the "Transaction Documents") has been duly authorized
by the Company and, when executed and delivered by the Company, will be a valid
and binding agreement of the Company, enforceable in accordance with its terms
except as (x) the enforceability thereof may be limited by bankruptcy,
insolvency or similar laws affecting creditors' rights generally and (y) rights
of acceleration, if applicable, and the availability of equitable remedies may
be limited by equitable principles of general applicability.

                  (g) The execution and delivery by the Company of, and the
performance by the Company of its obligations under, each of the Transaction
Documents will not (1)(A) contravene any provision of applicable law or the
certificate of incorporation or by-laws of the Company or any agreement or other
instrument binding upon the Company or its subsidiary that is material to the
Company and its subsidiary, taken as a whole, or any judgment, order or decree
of any governmental body, agency or court having jurisdiction over the Company
or any subsidiary, (B) or result in a breach of or constitute (upon notice or
lapse of time or both) a default under any indenture, mortgage, agreement,
contract or other material instrument binding upon the Company or its subsidiary
that is material to the Company and its subsidiary, taken as a whole, or result
in the creation or imposition of any lien, security interest, mortgage, pledge,
charge or other encumbrance, of any material nature whatsoever, upon any
properties or assets of the Company, and (2) no consent, approval, authorization
or order of, or qualification with, any governmental body or agency or other
party (other than consent by First Union National Bank which has been obtained)
is required for the performance by the Company or its subsidiary of its
obligations under this Agreement or the Registration Rights Agreement except
such as may be required by and has been obtained (except in connection with the
resale of the Underlying Common Stock) pursuant to the securities or Blue Sky
laws of the various states in connection with the offer and sale of the
Securities.

                  (h) Since the respective dates as of which information is
given in the Memorandum, and except as described in the Memorandum, there has
not occurred any material adverse change, or any development involving a
prospective material adverse change, in the condition, financial or otherwise,
or in the earnings, business or operations of the Company and its subsidiary,
taken as a whole, from those set forth in the Memorandum.

                  (i) There are no legal or governmental proceedings pending or,
to the best of the Company's knowledge, threatened and to the best of the
Company's knowledge investigations by any governmental body pending to which the
Company or its subsidiary is a party or to which any of the properties of the
Company or its subsidiary is subject, or related to environmental or
discrimination matters, or which could have an adverse effect on the power or




                                      -3-
<PAGE>   4

ability of the Company to perform its obligations under this Agreement or the
Registration Rights Agreement or to consummate the transactions contemplated by
the Memorandum, other than proceedings accurately described in all material
respects in the Memorandum and proceedings that would not have a material
adverse effect on the Company and its subsidiary, taken as a whole.

                  (j) The Company has not directly, or through any agent, (i)
sold, offered for sale, solicited offers to buy or otherwise negotiated in
respect of either the Securities or any security (as defined in the Securities
Act) which is or will be integrated with the sale of the Securities in a manner
that would require the registration under the Securities Act of the Securities
or (ii) engaged in any form of general solicitation or general advertising or
similar conduct in connection with the offering and sale of the Securities (as
those terms are used in Regulation D under the Securities Act) or in any manner
involving a public offer or sale within the meaning of Section 4 (2) of the
Securities Act. The Company is selling the Securities in compliance with an
exemption from the Securities Act. Notwithstanding the above, the Company shall
register the resale of the Underlying Common Stock pursuant to the terms of the
Registration Rights Agreement.

                  (k) The Company has not been advised, and has no reason to
believe, that either it or any of its subsidiaries is not conducting its
business in compliance with all applicable laws, rules and regulations of the
jurisdictions in which it is conducting business, including, without limitation,
all applicable local, state and federal environmental laws and regulations;
except where failure to be so in compliance would not materially adversely
affect the condition (financial or otherwise), business, results of operations
or prospects of the Company and its subsidiary.

                  (l) The authorized capital stock of the Company consists of
23,529,411 shares of Common Stock, of which 9,379,411 shares are issued and
outstanding as of November 23, 1998 and 5,882,353 shares of preferred stock of
which 2,000,000 shares are designated as Series I Preferred Stock, and no shares
of preferred stock are issued and outstanding prior to the consummation of the
transactions contemplated by this Agreement. Each outstanding share of capital
stock of the Company is validly authorized and issued, fully paid and
nonassessable, without any personal liability attaching to the ownership
thereof, and has not been issued and is not owned or held in violation of any
preemptive or similar rights of shareholders. There is no commitment, plan or
arrangement to issue, and no outstanding option, warrant or other instrument
which by its terms is convertible into, or exercisable for, preferred stock or
Common Stock, except as may be properly described in the Memorandum.

                  (m) All of the outstanding shares of the subsidiary of the
Company have been duly authorized and validly issued and are fully paid and
nonassessable, without any personal liability attaching to the ownership
thereof. The Company's ownership of the subsidiary is as set forth in the
Memorandum, and the shares of such subsidiary owned by the Company are owned of
record and beneficially by the Company, directly, free and clear of any security
interests, liens, encumbrances, equities or other claims.




                                      -4-
<PAGE>   5

                  (n) Except as disclosed in the Memorandum, to the knowledge of
the Company, the Company and/or its subsidiary own or possess adequate licenses
or other rights to use, free and clear of all liens, charges and encumbrances
and restrictions of any kind whatsoever other than existing licenses granted by
the Company and/or its subsidiary, all patents, patent rights, inventions, trade
secrets, licenses, know-how, proprietary techniques, including processes and
substances, trademarks, service marks, trade names, and copyrights that are
described in the Memorandum. The Company is not aware of any claim by a third
party regarding infringement on such party's intellectual property. The Company
requires all employees, agents, consultants and independent contractors to
execute confidentiality and non-disclosure agreements prior to being granted
access to the Company's facilities or being exposed to any confidential
information in the Company's custody or control.

                  (o) Except as set forth in the financial statements included
in the Memorandum, neither the Company nor its subsidiary is aware of any
material liability (whether asserted or unasserted, absolute or contingent,
accrued or unaccrued, liquidated or unliquidated, and whether due or to become
due).

                  (p) The Company and its subsidiary have filed or caused to be
filed, in a timely manner, all income tax returns, all material tax returns,
reports and declarations which are required to be filed by it in the ordinary
course of business and in accordance with all applicable laws and regulations.
All information in such tax returns, reports and declarations is complete and
accurate in all material respects. The Company and its subsidiary has paid or
caused to be paid all taxes due and payable or claimed due and payable in any
assessment received by it, and has collected, deposited and remitted in
accordance with all applicable laws, all sales and/or use taxes applicable to
the conduct of its business, except taxes the validity of which are being
contested in good faith by appropriate proceedings diligently pursued and
available to the Company or its subsidiary, as the case may be, and with respect
to which adequate reserves have been set aside on the Company's or its
subsidiary's books. Adequate provision has been made for the payment of all
accrued and unpaid federal, state, local, foreign and other taxes whether or not
yet due and payable and whether or not disputed.

                  (q) The Company represents and warrants that the information
contained in the following documents is true and correct in all material
respects as of their respective filing dates:

                           (i) the Company's Annual Report on Form 10-K for the
fiscal year ended September 30, 1997;

                           (ii) the Company's Quarterly Reports on Form 10-Q
required to be filed with the SEC for the three-month periods ended December 31,
1997, March 31, 1998 and June 30, 1998;

                           (iii) the Company's Current Reports on Form 8-K filed
with the SEC since September 30, 1997, if any; and





                                      -5-
<PAGE>   6

                           (iv) Notice of Annual Meeting and Proxy Statement for
the Company's 1998 Annual Meeting of Stockholders.

                  (r) The Company has filed with the Commission all reports
("SEC Reports") required to be filed by its under the Securities Exchange Act of
1934, as amended (the "Exchange Act"). All of the SEC Reports filed by the
Company comply in all material respects with the requirements of the Exchange
Act. None of the SEC Reports contains, as of the respective dates thereof, any
untrue statement of a material fact or omits to state any material fact required
to be stated therein or necessary to make the statements therein not misleading
in light of the circumstances under which they were made. All financial
statements contained in the Memorandum and the SEC Reports have been prepared in
accordance with generally accepted accounting principles consistently applied
("GAAP"). Each balance sheet presents fairly in accordance with GAAP the
financial position of the Company or its subsidiary, as applicable, as of the
date of such balance sheet, and each statement of operations, of stockholders'
equity and of cash flows presents fairly in accordance with GAAP the results of
operations, the stockholders' equity and the cash flows of the Company or its
subsidiary, as applicable, for the periods then ended.

                  (s) The Company is not aware of any Year 2000 non-compliance
issues internal to the Company and its subsidiary, including but not limited to
liability on the part of the Company or its subsidiary, remediation costs, or
risks associated with non-compliance by information technology and
non-information technology systems of the Company, that are likely to result in
any material, adverse effect on the business, financial condition or results of
operations of the Company or its subsidiary. To the Company's knowledge, without
independent investigation, no third party Year 2000 non-compliance is reasonably
likely to have a material adverse effect on the Company.

                  2. REPRESENTATIONS AND WARRANTIES OF THE PURCHASERS. Each
Purchaser hereby represents and warrants to the Company, and agrees with the
Company, that as of the date hereof:

                  (a) Such Purchaser is a corporation duly organized, validly
existing and in good standing under the laws of the jurisdiction of its
incorporation and has full right and power to execute and deliver this Agreement
and all other agreements and instruments contemplated hereby to which such
Purchaser is a party, and to perform its obligations hereunder and thereunder.
The execution, delivery and performance of this Agreement and all other
agreements and instruments contemplated hereby to which such Purchaser is a
party have been duly authorized by all necessary corporate action by such
Purchaser.

                  (b) No consent, approval or authorization of any persons or
entities is required in connection with such Purchaser's execution or delivery
of this Agreement or consummation of the transactions contemplated hereby.

                  (c) The Securities are being purchased for such Purchaser's
own account, for investment purposes only, not for the account of any other
person, and not with a view to distribution, assignment or resale to others or
fractionalization, contrary to applicable securities 




                                      -6-
<PAGE>   7

laws. Such Purchaser further acknowledges that the offering and sale of the
Preferred Stock has not been filed with or reviewed by the Securities and
Exchange Commission because of the Company's representations that this is
intended to be a nonpublic offering pursuant to Section 4(2) and Rule 506 of
Regulation D of the Securities Act.

                  (d) Such Purchaser agrees that it will not sell, transfer or
otherwise dispose of any of the Securities unless they are registered under the
Securities Act or unless an exemption from such registration is available. To
transfer the Preferred Stock or the Underlying Common Stock if no registration
statement is then available, a Purchaser may, at the request of the Company,
submit to the Company an opinion of counsel reasonably satisfactory to the
Company that the proposed sale, transfer or disposition does not result in a
violation of the Securities Act or any applicable "blue sky" laws (collectively,
the "Securities Laws"); provided, HOWEVER, that the Company will not require
opinions of counsel for transactions made pursuant to Rule 144 as long as the
Purchaser provides the Company with an appropriate broker's letter.

                  (e) Such Purchaser represents that it is an "accredited
investor" as such term is defined in Rule 501 of Regulation D promulgated under
the Securities Act.

as soon as practicable but in any event on or prior to the date ninety (90) days
following the date hereof (the "Filing Date"), a Registration Statement for an
offering to be made on a continuous basis pursuant to Rule 415 under the

Securities covered by such Registration Statement.

                           (iv) In the event (A) of the happening of any event
of the kind described in Section 3(b)(ii), 3(b)(iii), 3(b)(iv), 3(b)(v) or
3(b)(vi) hereof or (B) that, in the judgment of the Company, it is advisable to
suspend use of the Prospectus for a discrete period of time due to pending
material corporate developments or similar materials that have not yet been

disclosure is reasonably likely to be detrimental to the Company, the Company
shall deliver a certificate in writing, signed by an authorized executive
officer of the Company, to the Holders to the effect of the foregoing and, upon

incorporated or deemed incorporated by reference in such Prospectus. The Company

as practicable and, in the case of a pending development or event referred to in
this Section, as soon as the earlier of (x) public disclosure of such pending
material corporate development or similar material event or (y) the date upon
which, in the good faith judgment of the Company, public disclosure of such
material corporate development or similar material event would not be reasonably
likely to be detrimental to the Company. Notwithstanding the foregoing, the
Company shall not under any circumstances be entitled to exercise its right
under this Section 2(a)(iv) to suspend the use of the Registration Statement
except as follows: The Company may suspend the use of the Registration Statement
in accordance with this Section 2(a)(iv) for a period (such period being
"Deferral Period") not to exceed (i) an aggregate of 45 days (in no more than
two separate periods) in any three-month period and (ii) an aggregate of 90 days
(in no more than four separate periods) in any 12-month period, and the period
in which the use of the Registration Statement is suspended shall not exceed
fifteen (15) days unless the Company shall deliver to the Holders a second
notice to the effect set forth above, which shall have the effect of extending
the period during which the use of the Registration Statement is deferred by up
to an additional fifteen (15) days, or such shorter period of time as is
specified in such second notice.

                           (v) The parties hereto agree that the Holders of
Registrable Securities will suffer damages, and that it would not be feasible to
ascertain the extent of such damages with precision, if (A) the Shelf
Registration has not been filed on or prior to the Filing Date, (B) the Shelf
Registration is not declared effective within 90 days after the Filing Date, (C)
prior to the end of the Effectiveness Period, the SEC shall have issued a stop
order suspending the effectiveness of the Shelf Registration or proceedings have
been initiated with respect of the Shelf Registration under Section 8(d) or 8(e)
of the Securities Act or (D) the aggregate number of 



                                      -4-
<PAGE>   5

days in any Deferral Period exceeds the number permitted pursuant to Section
2(a)(iv) hereof (each of the events of a type described in any of the foregoing
clauses (A) through (D) are individually referred to herein as an "Event," and
the Filing Date in the case of clause (A), the 90th day after the Filing Date,
in the case of clause (B), the date on which the effectiveness of the Shelf
Registration has been suspended or proceedings with respect to the Shelf
Registration under Section 8(d) or 8(e) of the Securities Act have been
commenced in the case of clause (C), and the date on which the number of days in
any Deferral Period exceeds the number permitted by Section 2(a)(iv) hereof in
the case of clause (D), being referred to herein as an "Event Date"). Events
shall be deemed to continue until the date of the termination of such Event,
which shall be the following dates with respect to the respective types of
Events: the date the Registration Statement is filed in the case of an Event of
the type described in clause (A), the date the Shelf Registration becomes
effective, in the case of an Event described in clause (B), the date that all
stop orders suspending effectiveness of the Shelf Registration have been removed
and the proceedings initiated with respect to the Shelf Registration under
Section 8(d) or 8(e) of the Securities Act have terminated, as the case may be,
in the case of Events of the types described in clause (C), and termination of
the Deferral Period which caused the aggregate number of days in any Deferral
Period to exceed the number permitted by Section 2(a)(iv) to be exceeded in the
case of Events of the type described in clause (D).

                  Accordingly, upon the occurrence of any Event and until such
time as there are no Events which have occurred and are continuing (a "Damages
Accrual Period"), commencing on the Event Date on which such Damages Accrual
Period began, the Company agrees to pay, as liquidated damages, and not as a
penalty, an additional amount (the "Specified Damages"): (A) to each holder of
Series I Preferred Stock, accruing at a rate equal to one-half of one percent
per annum (50 basis points) calculated on an amount equal to the product of (x)
the Liquidation Preference (as defined in the Certificate of Designation) times
(y) the number of shares of Series I Preferred Stock held by such holder; and
(B) if the Damages Accrual Period continues for a period in excess of thirty
(30) days from the Event Date, from and after the end of such (30) day period
until such time as there are no Events which have occurred and are continuing,
to each holder of Series I Preferred Stock, accruing at a rate equal to three
quarters of one percent per annum (75 basis points) calculated on an amount
equal to the product of (x) the Liquidation Preference (as defined in the
Certificate of Designation) times (y) the number of shares of Series I Preferred
Stock held by such holder. Notwithstanding the foregoing, no Specified Damages
shall accrue under clause (A) of the preceding sentence during any period for
which Specified Damages accrue under clause (B) of the preceding sentence or as
to any Registrable Securities from and after the earlier of (x) the date such
securities are no longer Registrable Securities and (y) expiration of the
Effectiveness Period. The rate of accrual of the Specified Damages with respect
to any period shall not exceed the rate provided for in this paragraph
notwithstanding the occurrence of multiple concurrent Events.

                  The Specified Damages due shall be paid by the Company to the
Record Holders on each Damages Payment Date by wire transfer of immediately
available funds to the accounts specified by them or by mailing checks to their
registered addresses as they appear in the register of the Company for the
Registrable Securities or Common Stock, if no such accounts have been specified
on or before the Damages Payment Date.

                  (b)      DEMAND REGISTRATION.

                           (i) A Holder or Holders holding not less than 50% of
the Registrable Securities may make a written request (a "Demand Request") for
registration under the Securities Act of all or part of its Registrable
Securities in a "firm commitment" underwritten offering (a "Demand
Registration"); PROVIDED that the Company shall not be obligated (A) to effect a
Demand Registration for the registration of Registrable Shares, the market value
of which is less than $15 million (as determined by the average of the closing
price for the Registrable Securities for the 20 trading dates immediately prior
to the delivery of notice to the Company), (B) to effect a registration of any
Registrable Securities within 180 days after any underwritten offering of equity
securities by the Company or (C) to effect a Demand Registration on more than
one occasion. Such request will specify the number of shares of Registrable
Securities proposed to be sold. Subject to Section 2(b)(iii), the Company shall
file a registration statement with respect to the Demand Registration as soon as
practicable thereafter and in any event within 90 days after receiving a Demand
Request (such 90th day being referred to herein as the "REQUIRED FILING DATE")
and shall use its best efforts to cause the same to be declared effective by the
Commission as promptly as practicable after such filing.

                           (ii) The Company shall deliver notice to all other
Holders within fifteen business days of receiving a Demand Request. Holders
receiving such notice may elect to participate in the request by notifying the
party or parties who delivered such notice within fifteen business days of the
receipt thereof of the intention to participate and the number of shares of
Registrable Securities such Holder wants to sell.

                           (iii) The Holders of a majority of the Registrable
Securities to be registered pursuant to the Demand Registration shall select the
managing Underwriters and any additional investment bankers and managers to be
used in connection with the offering; PROVIDED that such managing Underwriters
and additional investment bankers must be reasonably satisfactory to the
Company.

                           (iv) The Company may, in its sole discretion, decline
to grant a Demand Request on one occasion. In such event, the Demand Request
shall be deemed not to have been made for the purpose of Section 2(b)(i) hereof,
provided, however, that the holders may not make another request within 120 days
following the denial by the Company to grant such Demand Request.

                           (v) Notwithstanding anything contained herein, if the
managing underwriter of an offering described in Section 2(b)(i) above delivers
a written opinion to the Company that marketing considerations require a
limitation on the number of shares offered pursuant to any registration
statement, then the Company shall include in such registration (A) first, the
securities being offered for the account of the Holders of Registrable
Securities, (B) second, the number of equity securities that the Company wishes
to include, and (C) third, the number of equity securities requested by holders
of equity securities with registration rights that in the opinion of such
underwriter, can be sold, pro rata among such holders on the basis of the amount
of equity securities requested to be included by each such holders.




                                      -6-
<PAGE>   7

                           (vi) A registration pursuant to this Section will not
be deemed to have been "effected" if it is withdrawn at the request of the
holders of the majority of the Registrable Securities to be included therein.

                  (c)      PIGGYBACK REGISTRATION.

                           (i) If the Company proposes to file a registration
statement under the Securities Act with respect to an underwritten offering of
equity securities (A) for the Company's own account or (B) for the account of
any of the holders of its equity securities, then the Company shall give written
notice of such proposed filing to each Holder as soon as practicable (but in no
event less than 20 business days before the anticipated filing date), and such
notice shall offer such Holder the opportunity to register such number of shares
of Registrable Securities as such Holder may request on the same terms and
conditions as the Company's or such holder's equity securities (a "Piggyback
Registration"). Each Holder who desires to have its Registrable Securities
included in such registration statement shall so advise the Company in writing
(stating the number of shares of Common Stock desired to be registered) within
15 business days after the date of such notice from the Company. Any Holder
shall have the right to withdraw such request for inclusion of such Holder's
Registrable Securities in any registration statement pursuant to this section by
giving written notice to the Company of such withdrawal prior to the effective
date of the Registration Statement. Subject to Section 2(c)(ii) below, the
Company shall include in such registration statement all such Registrable
Securities requested to be included therein; PROVIDED, HOWEVER, that the Company
may at any time withdraw or cease proceeding with any such registration if it
shall at the same time withdraw or cease proceeding with the registration of all
other securities originally proposed to be registered.

                           (ii) Notwithstanding anything contained herein, if
the managing Underwriter of an offering described in Section 2(c)(i) above
delivers a written opinion to the Company that marketing considerations require
a limitation on the number of shares offered pursuant to any registration
statement, then the Company shall include in such registration (A) first, the
securities being offered for the account of the Company, and (B) second, the
number of Registrable Securities requested to be included that, in the opinion
of such Underwriter, can be sold, pro rata among the Holders on the basis of the
amount of Registrable Securities requested to be included by each Holder.

                  3. REGISTRATION PROCEDURES. In connection with the Company's
registration obligations under Section 2 hereof, the Company shall as
expeditiously as possible:

                  (a) Prepare and file with the Commission a registration
statement on any form for which the Company then qualifies and which counsel for
the Company shall deem appropriate and available for the sale of the Registrable
Securities to be registered thereunder in accordance with the intended method of
distribution thereof (including in a Rule 415 offering), and use its reasonable
efforts to cause such filed registration statement to become effective as
promptly as practicable, and thereafter prepare and file with the Commission
such amendments and supplements to such registration statement and the
prospectus used in connection therewith as may be necessary to keep such
registration statement effective (i) for a period of not less than 120 days in
the case of any registration other than the Shelf Registration plus the period
of any 



                                      -7-
<PAGE>   8

delay or suspension of use of a prospectus pursuant to Section 2(a)(iv) hereof,
and (ii) in the case of the Shelf Registration through the Effectiveness Period
plus the period of any delay or suspension of use of a prospectus pursuant to
Section 2(a)(iv) hereof.

                  (b) Notify the Holders, promptly, and confirm such notice in
writing, (i) when a Prospectus, any Prospectus supplement, a Registration
Statement or a post-effective amendment to a Registration Statement has been
filed with the SEC, and, with respect to the Registration Statement or any
post-effective amendment, when the same has become effective, (ii) of any
request by the SEC or any other federal or state governmental authority for
amendments or supplements to the Registration Statement or related Prospectus or
for additional information, (iii) of the issuance by the SEC or any other
federal or state governmental authority of any stop order suspending the
effectiveness of the Registration Statement or the initiation or threatening of
any proceedings for that purpose, (iv) of the receipt by the Company of any
notification with respect to the suspension of the qualification or exemption
from qualification of any of the Registrable Securities for sale in any
jurisdiction or the initiation or threatening of any proceeding for such
purpose, (v) of the existence of any fact or happening of any event which makes
any statement of a material fact in the Registration Statement or related
Prospectus or any document incorporated or deemed to be incorporated therein by
reference untrue or which would require the making of any changes in the
Registration Statement or Prospectus in order that, in the case of the
Registration Statement, it will not contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein not misleading, and that in the case of
the Prospectus, it will not contain any untrue statement of a material fact or
omit to state any material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading, and (vi) of the Company's good faith determination that a
post-effective amendment to the Registration Statement would be appropriate.

                  (c) Use its reasonable best efforts to obtain the withdrawal
of any order suspending the effectiveness of the Registration Statement, or the
lifting of any suspension of the qualification (or exemption from qualification)
of any of the Registrable Securities for sale in any jurisdiction, at the
earliest possible moment.

                  (d) Prior to filing a Registration Statement or any amendment
or supplement thereto, furnish to each selling Holder, copies thereof, and
thereafter furnish to each such Holder such number of copies of such
registration statement, amendment and supplement thereto (in each case including
all exhibits thereto and documents incorporated by reference therein) and the
prospectus included in such registration statement (including each preliminary
prospectus) as each such Holder may reasonably request from time to time in
order to facilitate the sale of the Registrable Securities.

                  (e) Prior to any public offering of Registrable Securities, to
register or qualify (or obtain an exemption from such registration or
qualification of) such Registrable Securities for offer and sale under the
securities or Blue Sky laws of such jurisdictions within the United States as
any Holder reasonably requests in writing, keep each such registration or
qualification (or exemption therefrom) effective during the period the
Registration Statement is required to be kept effective and do any and all other
acts or things necessary or advisable to enable the 



                                      -8-
<PAGE>   9

disposition in such jurisdictions of the Registrable Securities covered by the
Registration Statement; PROVIDED, that the Company shall not be required to (A)
qualify generally to do business in any jurisdiction where it is not then so
qualified or (B) take any action that would subject it to general service of
process in suits or to taxation in any such jurisdiction where it is not then so
subject.

                  (f) Throughout the Effectiveness Period (other than during a
Deferral Period), immediately upon the existence of any fact or the occurrence
of any event as a result of which the Registration Statement shall contain any
untrue statement of a material fact or omit to state any material fact required
to be stated therein or necessary to make the statements therein not misleading,
or a Prospectus shall contain any untrue statements of a material fact or omit
to state any material fact or omit to state any material fact required to be
stated therein or necessary to make each statement therein not misleading,
promptly prepare and file a post-effective amendment to the Registration
Statement or a supplement to the related Prospectus or any document incorporated
therein by reference or file any other required document (such as a current
Report on Form 8-K) that would be incorporated by reference into the
Registration Statement so that the Registration Statement shall not contain any
untrue statement of a material fact or omit to state any material fact required
to be stated therein or necessary to make the statements therein not misleading,
and so that the Prospectus will not contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading, as thereafter delivered to the
Holders, and, in the case of a post-effective amendment to the Registration
Statement, use its reasonable best efforts to cause it to become effective as
soon as practicable.

                  (g) Comply with all applicable rules and regulations of the
SEC and make generally available to the holders of its securities earnings
statements (which need not be audited) satisfying the provisions of Section
11(a) of the Securities Act and Rule 158 thereunder (or any similar rule
promulgated under the Securities Act) no later than 45 days after the end of any
12-month period (or 90 days after the end of any 12-month period if such period
is a fiscal year) (i) commencing at the end of any fiscal quarter in which
Registrable Securities are sold to Underwriters in a firm commitment or best
efforts underwritten offering, and (ii) if not sold to Underwriters in such an
offering, commencing on the first day of the first fiscal quarter of the Company
commencing after the effective date of the Registration Statement, which
statements shall cover said 12-month period.

                  (h) Cooperate with the Holders of Registrable Securities to
facilitate the timely preparation and delivery of certificates representing
Common Stock to be issued and not bearing any restrictive legends; and enable
such Registrable Securities to be in such denominations and registered in such
names as such Holders may request.

                  (i) Cause the Common Stock covered by the Registration
Statement to be listed and registered on each national securities exchange or
quoted on the automated quotation system of a national securities association on
which the Company's "Common Stock" is then listed, no later than the effective
date of the Registration Statement and, in connection therewith, 



                                      -9-
<PAGE>   10

to the extent applicable, to make such filings under the Exchange Act (e.g., the
filing of a Registration Statement on Form 8-A) and to have such filings
declared effective thereunder.

                  (j) Cooperate and assist in any filings required to be made
with the National Association of Securities Dealers, Inc.

                  (k) If reasonably requested by the managing underwriter or
underwriters or a Holder of Registrable Securities being sold in connection with
an underwritten offering, promptly incorporate in a prospectus supplement or
post-effective amendment such information as the managing underwriters and the
Holders of a majority of the Registrable Securities (on a Common Stock
equivalent basis) being sold in such underwritten offering agree should be
included therein relating to the sale of the Registrable Securities, including,
without limitation, information with respect to the aggregate number of shares
of Registrable Securities being sold to such underwriters, the purchase price
being paid therefor by such underwriters and with respect to any other terms of
the underwritten offering of the Registrable Securities to be sold in such
offering; and promptly make all required filings of such prospectus supplement
or post-effective amendment.

                  (l) Cooperate with the selling Holders of Registrable
Securities and the managing underwriters, if any, to facilitate the timely
preparation and delivery of certificates representing Registrable Securities to
be sold and not bearing any restrictive legends; and enable such Registrable
Securities to be in such denominations and registered in such names as the
managing underwriters may request at least two Business Days prior to any sale
of Registrable Securities to the underwriters.

                  (m) In the case of a Demand registration under Section 2(b):

                           (i) enter into such customary agreements (including
underwriting agreements in customary form) and take all such other actions as
the holders of a majority of the Registrable Securities being sold or the
underwriters, if any, reasonably request in order to expedite or facilitate the
disposition of such Registrable Securities (including, without limitation,
effecting a stock split or a combination of shares);

                           (ii) at the request of any seller of Registrable
Securities, use its best efforts to furnish on the date that Restricted
Securities are delivered to the underwriters for sale pursuant to such
registration an opinion dated such date of counsel representing the Company for
the purposes of such registration, addressed to the underwriters and to such
seller, stating that such registration statement has become effective under the
Securities Act and that (A) to the best knowledge of such counsel, no stop order
suspending the effectiveness thereof has been issued and no proceedings for that
purpose have been instituted or are pending or contemplated under the Securities
Act, (B) the registration statement, the related prospectus and each amendment
or supplement thereof comply as to form in all material respects with the
requirements of the Securities Act (except that such counsel need not express
any opinion as to financial statements contained therein) and (iii) to such
other effects as reasonably may be requested by counsel for the underwriters or
by such Holder or its counsel;





                                      -10-
<PAGE>   11

                           (iii) make available for inspection by any seller of
Registrable Securities, any underwriter participating in any disposition
pursuant to such registration statement, and any attorney, accountant or other

records, pertinent corporate documents and properties of the Company, and cause
the Company's officers, directors, employees and independent accountants to
supply all information reasonably requested by any such seller, underwriter,

                           (iv) obtain a cold comfort letter from the Company's
independent public accountants in customary form and covering such matters of
the type customarily covered by cold comfort letters as the holders of a
majority of the Registrable Securities being sold reasonably request (provided
that such Registrable Securities constitute at least 10% of the securities
covered by such registration statement).

                  (n) In the case of any nonunderwritten offering: (1) obtain
opinions of counsel to the Company at the time of effectiveness of such
Registration Statement covering such offering and updates thereof of customary

in such offering and covering matters that are no more extensive in scope than
would be customarily covered in opinions obtained in secondary underwritten
offerings by issuers with similar market capitalization and reporting and
financial histories; (2) obtain "cold comfort" letters from the independent
certified public accountants of the Company at the time of effectiveness of such
Registration Statement and, upon the request of the Holders of a majority of the
Registrable Securities (on a Common Stock equivalent basis) covered by such

addressed to each Holder of Registrable Securities participating in such
offering and covering matters that are no more extensive in scope than would be
customarily covered in "cold comfort" letters and updates obtained in secondary
underwritten offerings by issuers with similar market capitalization and
reporting and financial histories, PROVIDED that any letter or update described
in this clause (2) shall only be required to the extent such letters are being
issued in respect of nonunderwritten secondary offerings under then prevailing

shall pay all costs, fees and expenses related thereto.

                  4. REGISTRATION EXPENSES. All fees and expenses incident to
the Company's performance of or compliance with this Agreement shall be borne by
the Company whether or not the Registration Statement becomes effective,
provided, however, that with respect to any Registration Statement filed
pursuant to Section 2(b) hereof all reasonable fees and out-of-pocket expenses
other than fees and expenses described in clause (vii) below shall be borne by
the selling Holders in proportion to the number of shares of Registrable

                  5.       INDEMNIFICATION AND CONTRIBUTION.

                  (a) INDEMNIFICATION BY THE COMPANY - REGISTRABLE SECURITIES.
The Company agrees to indemnify and hold harmless each selling Holder and each
Person, if any, who controls each selling Holder within the meaning of either
Section 15 of the Securities Act or Section 20 of the Exchange Act, and the
officers, directors, Affiliates, employees and agents of each of the foregoing,
from and against any and all losses, claims, judgments, damages and liabilities
(including reasonable fees, disbursements and other charges of counsel) arising
out of or based upon any untrue statement or alleged untrue statement of a
material fact contained in any Registration Statement (as amended or
supplemented if the Company shall have furnished any amendments or supplements
thereto) or any preliminary or final Prospectus contained therein or arising out
of or based upon any omission or alleged omission to state in any such
Registration Statement or Prospectus a material fact required to be stated
therein or necessary to make the statements therein (as to a preliminary or
final prospectus), in light of the circumstances under which they were made, not
misleading, and any failure by the Company to fulfill any undertaking in any
Registration Statement, except insofar as such losses, claims, judgments,
damages or liabilities arise out of or are based upon any such untrue statement
or omission or alleged untrue statement or omission made in conformity with
information relating to such Holder or the plan of distribution of Registrable
Securities to be sold by such Holder, in each case furnished in writing to the
Company by such Holder expressly for use therein; PROVIDED that the foregoing
indemnity agreement with respect to any preliminary prospectus shall not inure
to the benefit of a selling Holder with respect to any loss, claim, damage or
liability relating to a purchaser if a copy of the final prospectus was
furnished to such selling Holder and was not 




                                      -12-
<PAGE>   13

provided to such purchaser and such final prospectus would have cured the defect
giving rise to such loss, claim, damage or liability. The Company agrees to
reimburse the Purchasers for reasonable fees and expenses incurred investigating
claims subject to indemnification under this Section 5(a). The Company also
agrees to indemnify any Underwriters of the Registrable Securities, their
officers and directors and each person who controls such Underwriters on
substantially the same basis as that of the indemnification of the selling
Holders provided in this Section 5(a).

                  (b) INDEMNIFICATION BY SELLING HOLDERS - REGISTRABLE
SECURITIES. Each selling Holder agrees severally and not jointly to indemnify
and hold harmless the Company, and each person, if any, who controls the Company
within the meaning of either Section 15 of the Securities Act or Section 20 of
the Exchange Act, and the officers, directors, Affiliates, employees and agents
of each of the foregoing, from and against any and all losses, claims,
judgments, damages and liabilities (including reasonable fees, disbursements and
other charges of counsel) arising out of or based upon any untrue statement or
alleged untrue statement of a material fact contained in any Registration
Statement (as amended or supplemented if the Company shall have furnished any
amendments or supplements thereto) or any preliminary or final Prospectus
contained therein, or arising out of or based upon any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading, but only insofar as such losses, claims,
judgments, damages or liabilities arise out of or are based upon any such untrue
statement or omission or alleged untrue statement or omission made in conformity
with information relating to such Holder or the plan of distribution of
Registrable Securities to be sold by such Holder, in each case furnished in
writing to the Company by such Holder expressly for use therein. Each Holder, by
exercising its registration rights hereunder, also agrees to indemnify and hold
harmless any Underwriters of the Registrable Securities, their officers and
directors and each person who controls such Underwriters on substantially the
same basis as that to the indemnification of the Company provided in this
Section 5(b) subject to the limitations set forth in 5(e).

                  (c) CONDUCT OF INDEMNIFICATION PROCEEDINGS. In case any
proceeding (including any governmental investigation) shall be instituted
involving any person in respect of which indemnity may be sought pursuant to
Sections 5(a) or (b), such person (the "Indemnified Party") shall promptly
notify the person against whom such indemnity may be sought (the "Indemnifying
Party") in writing of such proceeding; provided, that the failure to notify the
Indemnifying Party shall not relieve it from any liability that it may have to
an Indemnified Party on account of the indemnity agreement contained in Sections
5(a) or (b) above except to the extent that the Indemnifying Party was actually
prejudiced by such failure, and in no event shall such failure relieve the
Indemnifying Party from any other liability that it may have to such Indemnified
Party. If the Indemnified Party, at its option, elects to defend any such
proceeding with counsel retained by it, the Indemnifying Party shall pay the
fees and disbursements of such counsel related to such proceeding. Upon the
request of the Indemnified Party, the Indemnifying Party shall retain counsel
reasonably satisfactory to such Indemnified Party to represent such Indemnified
Party and any others the Indemnifying Party may designate in such proceeding and
shall pay the fees and disbursements of such counsel related to such proceeding.
If, pursuant to 



                                      -13-
<PAGE>   14

the immediately preceding sentence, the Indemnified Party shall have requested
the Indemnifying party to retain counsel to represent such Indemnified Party
with respect to any such proceeding, any Indemnified party shall have the right
to retain its own counsel, but the fees and expenses of such counsel shall be at
the expense of such Indemnified Party unless (i) the Indemnifying Party and the
Indemnified Party shall have mutually agreed to the retention of such counsel or
(ii) the named parties to any such proceeding (including any impleaded parties)
include both the Indemnified Party and the Indemnifying Party and representation
of both parties by the same counsel would be inappropriate due to actual or
potential differing interests between them. It is understood that the
Indemnifying Party shall not, in connection with any proceeding or related
proceedings in the same jurisdiction, be liable for the fees and expenses of
more than one separate firm of attorneys (in addition to any local counsel) at
any time for all such Indemnified Parties, and that all such fees and expenses
shall be reimbursed as they are incurred. Any Indemnifying Party against whom
indemnity may be sought under this Section 5(c) shall not be liable to indemnify
any Indemnified Party if such Indemnified Party settles such claim or action
without the consent of the Indemnifying Party which shall not be unreasonably
withheld. The Indemnifying Party may not agree to any settlement of any such
claim or action, other than solely for monetary damages for which the
Indemnifying Party shall be responsible hereunder and with a full release of the
Indemnified Party, resulting in any remedy or relief applied to or against the
Indemnified Party, without the prior written consent of the Indemnified Party.

                  (d) CONTRIBUTION - - OFFERINGS. If the indemnification
provided for in Sections 5(a) or (b) is unavailable to an Indemnified Party in
respect of any losses, claims, judgments, damages or liabilities referred to
herein, then each such Indemnifying Party, in lieu of indemnifying such
Indemnified Party, shall contribute to the amount paid or payable by such
Indemnified Party as a result of such losses, claims, judgments, damages or
liabilities in such proportion as is appropriate to reflect the relative fault
of the Company, the selling Holders and the Underwriters in connection with the
statements or omissions that resulted in such losses, claims, judgments, damages
or liabilities, as well as any other relevant equitable considerations. The
relative fault of the Company, the selling Holders and the underwriters shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by such party and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission. If the allocation provided for above is not
permitted by applicable law, such contribution shall be based on such equitable
considerations as a court may determine to be relevant.

                  The Company and the selling Holders agree that it would not be
just and equitable if contribution pursuant to this Section 5(d) were determined
by pro rata allocation (even if the Underwriters were treated as one entity for
such purpose) or by any other method of allocation that does not take account of
the equitable considerations referred to in the immediately preceding paragraph.
The amount paid or payable by an Indemnified Party as a result of the losses,
claims, damages or liabilities referred to in the immediately preceding
paragraph shall be deemed to include, subject to the limitations set forth
above, any legal or other expenses reasonably incurred by such Indemnified Party
in connection with investigating or defending any such action or claim.

<PAGE>   15

                  (e) Notwithstanding the provisions of this Section 5, no
Underwriter shall be required to contribute or indemnify any amount in excess of
the amount by which the total price at which the Securities underwritten by it
and distributed to the public were offered to the public exceeds the amount of
any damages which such Underwriter has otherwise been required to pay by reason
of such untrue or alleged untrue statement or omission or alleged omission, and
no selling Holder shall be required to contribute or indemnify any aggregate
amounts in excess of the amount by which the net proceeds of the offering
(before deducting expenses) received by such selling Holder exceeds the amount
of any damages which such selling Holder has otherwise been required to pay by
reason of such untrue or alleged untrue statement or omission or alleged
omission. No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Securities Act) shall be entitled to indemnification or
contribution under this Section 5 from any Person who was not guilty of such
fraudulent misrepresentation.

                  6.       ADDITIONAL REGISTRATION RIGHTS PROVISIONS.

                  (a) PARTICIPATION IN REGISTRATIONS. No Person may participate
in any underwritten registered offering contemplated hereunder unless such
Person (a) agrees to sell its securities on the basis provided in any customary
underwriting arrangements approved by the Persons entitled hereunder to approve
such arrangements and (b) completes and executes all questionnaires, powers of
attorney, indemnities, customary underwriting agreements and other documents
reasonably required under the terms of such underwriting arrangements and these
Registration Rights. No Person may participate in a registered offering pursuant
to the Shelf Registration unless such Person provides information reasonably
requested by the Company customarily required to effect registration of the
resale of the Common Stock. Notwithstanding the above, with respect to a
Piggyback Registration, the Holders shall not be required to provide
indemnification except to the extent provided pursuant to this Agreement. The
Holders shall only be required to give representations and warranties that are
customary for selling shareholders.

                  (b) LOCKUP AGREEMENTS. Each Holder, by exercising its
registration rights hereunder, agrees not to offer, sell, contract to sell or
otherwise dispose of any Registrable Securities, or any securities convertible
into or exchangeable or exercisable for such securities, during the 14 days
prior to, and during the 90-day period (or such lesser period as the lead or
managing underwriters may permit) beginning on, the effective date of such
Registration Statement (or the commencement of the offering to the public of
such Registrable Securities in the case of Rule 415 offerings) other than (i)
the Registrable Securities to be sold pursuant to such Registration Statement or
(ii) in a transaction not involving a public offering, provided that the
purchaser (or purchasers) of such shares agrees to be bound by such lock-up
restrictions for the remainder of the lock-up period.

                  (c) With a view to making available to the holders of
Registrable Securities the benefits of certain rules and regulations of the SEC
which may permit the sale of the Registrable Securities to the public without
registration, the Company agrees to use its reasonable best efforts to:




                                      -15-
<PAGE>   16

                           (i) make and keep current public information
available, within the meaning of Rule 144 or any similar or analogous rule
promulgated under the Securities Act, at all times;

                           (ii) file with the SEC, in a timely manner, all
reports and other documents required under the Securities Act and Exchange Act;
and

                           (iii) so long as any party hereto owns any
Registrable Securities, furnish to such Person forthwith upon request a written
statement as to its compliance with the reporting requirements of said Rule 144,
the Securities Act and the Exchange Act; a copy of its most recent annual or
quarterly report; and such other reports and documents as such Person may
reasonably request in availing itself of any rule or regulation of the SEC
allowing it to sell such securities without registration.

                  (d) The Company will provide to any holder of a Registrable
Security, upon such persons' request, the information required by paragraph
(d)(4) of Rule 144A.

                  7.       MISCELLANEOUS.

                  (a) REMEDIES. In the event of a breach by the Company of its
obligations under this Agreement, each Holder of Registrable Securities, in
addition to being entitled to exercise all rights granted by law, including
recovery of damages, will be entitled to specific performance of its rights
under this Agreement. The Company agrees that monetary damages would not be
adequate compensation for any loss incurred by reason of a breach by it of any
of the provisions of this Agreement and hereby further agrees that, in the event
of any action for specific performance in respect of such breach, it shall waive
the defense that remedy of law would be adequate.

                  (b) NO CONFLICTING AGREEMENTS. The Company has not, as of the
date hereof, and shall not, on or after the date of this Agreement, enter into
any agreement with respect to its securities which conflicts with the rights
granted to the Holders of Registrable Securities in this Agreement. The Company
represents and warrants that the rights granted to the Holders of Registrable
Securities hereunder do not in any way conflict with the rights granted to the
holders of the Company's securities under any other agreements.

                  (c) AMENDMENTS AND WAIVERS. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers to or departures from the provisions hereof may not be
given, unless the Company has obtained the written consent of holders of a
majority of the then outstanding Common Stock constituting Registrable
Securities (with holders of Series I Preferred Stock deemed to be the holders,
for purposes of this Section, of the number of outstanding shares of Common
Stock into which such Series I Preferred Stock is convertible); provided,
however, that, if a Purchaser or its affiliates own at least 50% of the number
of shares of Preferred Stock such Purchaser purchased on the date hereof (shares
of Common Stock issued upon conversion of the Preferred Stock shall be included
in this calculation as shares of Preferred Stock), the provisions of this
Agreement may not be amended, modified or supplemented and waivers to or
departures from the provisions 



                                      -16-
<PAGE>   17

hereof may not be given without the written consent of such Purchaser.
Notwithstanding the foregoing, a waiver or consent to depart from the provisions
hereof with respect to a matter that relates exclusively to the rights of
Holders of Registrable Securities whose securities are being sold pursuant to
the Registration Statement and that does not directly or indirectly affect the
rights of other Holders of Registrable Securities may be given by Holders of at
least a majority of the Registrable Securities being sold by such Holders;
PROVIDED, that the provisions of this sentence may not be amended, modified or
supplemented except in accordance with the provisions of the immediately
preceding sentence.

                  (d) NOTICES. All notices and other communications provided for
or permitted hereunder shall be made in writing and shall be deemed given (i)

Agreement.

Holders of a specified percentage of Registrable Securities is required
hereunder, Registrable Securities held 



                                      -17-
<PAGE>   18

by the Company or its affiliates (other than Holders of Registrable Securities
or Preferred Stock if such Holders are deemed to be such affiliates solely by
reason of their holdings of such Registrable Securities or Preferred Stock and
other than the Purchasers) shall not be counted in determining whether such
consent or approval was given by the Holders of such required percentage.

                  (g) SUCCESSORS AND ASSIGNS. Any person who purchases any
Registrable Securities from the Purchaser shall be deemed, for purposes of this
Agreement, to be an assignee of the Purchaser. This Agreement shall inure to the
benefit of and be binding upon the successors and assigns of each of the parties
and shall inure to the benefit of and be binding upon each Holder of any
Registrable Securities. This Agreement may not be assigned by the Company

of counterparts and by the parties hereto in separate counterparts, each of

contracts made and performed within the state of New York without regard to
principles of conflicts of laws.

                  (k) SEVERABILITY. If any term, provision, covenant or
restriction of this Agreement is held to be invalid, illegal, void or
unenforceable, the remainder of the terms, provisions, covenants and
restrictions set forth herein shall remain in full force and effect and shall in
no way be affected, impaired or invalidated thereby, and the parties hereto

provision, covenant or restriction. It is hereby stipulated and declared to be
the intention of the parties that they would have executed the remaining terms,

         b.       [*]

2.       ADJUSTMENTS TO PURCHASE RELEASE UNIT PRICES

         Modifications to Unit Prices shall be made on the basis of the
following:

         a.       If in a Calendar Year, and within a three-month period, Buyer
                  places a Purchase Release(s) which, when added to a previous
                  Purchase Release(s), in the aggregate increases the quantity
                  of Hardware purchased such that a higher Solar Cell Quantity
                  Range is achieved, the Unit Price(s) for all effected Releases
                  will be modified to reflect the cumulative quantity of
                  Hardware so purchased under these conditions.

         b.       If in a Calendar Year, for a incremental Purchase Release(s)
                  which does not fall within the three-month stipulation of
                  Subparagraph a., above, no adjustment will be made to the Unit
                  Price of the prior Purchase Release; the Unit Price applicable
                  to the incremental Purchase Release will, however, be adjusted
                  provided that (1) in the aggregate a higher Solar Cell
                  Quantity Range is achieved, and (2) continuity of monthly
                  Subcontractor delivery is maintained.

         c.       In the event Hardware with a higher Solar Cell Efficiency
                  Rating is not available during a Calendar Year as identified
                  in this provision, Buyer may purchase available rated Hardware
                  in accordance with the stipulations of Subparagraph a. and b.,
                  above. Under such conditions, any Hardware aggregate
                  limitation imposed by the definition of a Calendar Year is
                  waived.

         Examples applicable to these subparagraphs can be found in APPENDIX I
to this Agreement.

                           (REVOLVING LINE OF CREDIT)


$8,000,000.00

                                                                  June 22, 1998

EMCORE CORPORATION
394 Elizabeth Avenue
Somerset, New Jersey 08873
(Hereinafter referred to as the "Borrower")

FIRST UNION NATIONAL BANK
550 Broad Street
Newark, New Jersey 07102
(Hereinafter referred to as the "Bank")

                  Borrower promises to pay to the order of Bank, in lawful money
of the United States of America, at its office indicated above or wherever else
Bank may specify, the sum of EIGHT MILLION AND NO/100 DOLLARS ($8,000,000.00) or
such sum as may be advanced and outstanding from time to time with interest on
the unpaid principal balance at the rate and on the terms provided in this
Promissory Note (including all renewals, extensions or modifications hereof,
this "Note").

                  SECURITY. This Note is secured by the Unconditional Guaranty
dated the date hereof, made by Thomas J. Russell, Jr., individually and the TJR
Holding Trust (collectively, the "Note Guarantors") and by the Collateral
described in the Pledge and Assignment Agreement of even date herewith made by
the Note Guarantors in favor of the Bank (collectively, the "TJR Documents").

                  INTEREST RATE. Interest shall accrue on the unpaid principal
balance of each Revolving Loan (defined herein) under this Note from the date
such Revolving Loan is made available to the Borrower at the at a rate equal to
one month LIBOR plus three-quarters of one percent (3/4%) per annum
("LIBOR-BASED RATE"), as determined by the Bank prior to the commencement of
each Interest Period. The LIBOR-Based Rate shall remain in effect, subject to
the provisions hereof, for the entire Interest Period for which it is
determined. Borrower acknowledges that the LIBOR- Based Rate is not represented
or intended to be the lowest or most favorable rate of interest offered by Bank.
"LIBOR" is the rate for U.S. dollar deposits of that many months maturity as
reported on Telerate page 3750 as of 11:00 a.m., London time, on the second
London business day before the relevant Interest Period begins (or if not so
reported, then as determined by Bank from another recognized source of interbank
quotation). The term 




<PAGE>   2

"Interest Period" means, initially, the period commencing on the date hereof and
ending June 30, 1998, and thereafter, each period commencing on the last day of
the immediately preceding Interest Period and ending one month thereafter, but
in no event after the Maturity Date; subject, however, to the following
provisions: (i) if any Interest Period would otherwise end on a day which is not
a New York business day, that Interest Period shall be extended to the next
succeeding New York business day unless the result of such extension would be to
carry such Interest Period into another calendar month, in which event such
Interest Period shall end on the immediately preceding New York business day;
and (ii) any Interest Period that begins on the last New York business day of a
calendar month (or on a day for which there is no numerically corresponding day
in the calendar month at the end of such Interest Period) shall end on the last
New York business day of a calendar month.

                  DEFAULT RATE. In addition to all other rights contained in
this Note, if a Default (defined herein) occurs and as long as a Default
continues, (a) Borrower shall no longer have the option to request a LIBOR-Based
Rate and (b) all outstanding Obligations shall bear interest at the Lending Rate
(s such term is defined in the Credit Agreement) plus 3% ("Default Rate"). The
Default Rate shall also apply from acceleration until the Obligations or any
judgment thereon is paid in full.

                  INDEMNIFICATION. The Borrower shall indemnify the Bank against
the Bank's loss or expense in employing deposits as a consequence of (i) the
Borrower's failure to make any payment when due under this Note, or (ii) any
prepayment of the Loan on a date other than the last day of an Interest Period
("INDEMNIFIED LOSS OR EXPENSE").

                  ADDITIONAL COSTS. If, at any time, a new, or a revision in any
existing law or interpretation or administration (including reversals) thereof
by any government authority, central bank or comparable agency imposes,
increases or modifies any reserve or similar requirement against assets,
deposits or credit extended by the Bank, or subjects the Bank to any tax, duty
or other charge (except tax on the Bank's net income), and any of the foregoing
increase the cost to the Bank of maintaining its commitment or reduce the amount
of any sum received or receivable by the Bank under this Note, within 15 days
after demand by the Bank, the Borrower agrees to pay the Bank such additional
amounts as will compensate the Bank for such increased costs or reductions
("ADDITIONAL COSTS").

                  MATCH FUNDING. The amount of such (i) Indemnified Loss or
Expense, or (ii) Additional Costs outlined above shall be determined, in the
Bank's sole discretion, based upon the assumption that the Bank funded 100% of
that portion of the Loan to which the LIBOR-Based Rate applies in the applicable
London interbank market.

                  UNAVAILABILITY OF INTEREST RATE. If, at any time, (i) the Bank
shall determine that, by reason of circumstances affecting foreign exchange and
interbank markets generally, LIBOR deposits in the applicable amounts are not
being offered to the Bank; or (ii) a new, or a revision in any existing law or
interpretation or administration (including reversals) thereof by any government
authority, central bank or comparable agency shall make it unlawful or
impossible for the Bank to honor its obligations under this Note, then (A) the
Bank's 



                                      -2-
<PAGE>   3

obligation, if any, to make or maintain a Revolving Loan at the LIBOR-Based Rate
shall be suspended, and (B) the applicable LIBOR-Based Rate shall, for the
remainder of the term of the Loan, immediately be converted to (x) the Lending
Rate (as such term is defined in the Credit Agreement) or (y) if the undersigned
has hedged the LIBOR-Based Rate by entering into an interest rate swap agreement
with the Bank, the rate of interest payable to the undersigned by the Bank as a
Floating Rate Payer under the terms of said swap agreement (plus the percentage
added to LIBOR above if not included in said rate of interest payable by the
Bank).

                  INTEREST AND FEE(S) COMPUTATION. (ACTUAL/360). Interest and
fees, if any, shall be computed on the basis of a 360-day year for the actual
number of days in the applicable period ("Actual/360 Computation"). The
Actual/360 Computation determines the annual effective yield by taking the
stated (nominal) rate for a year's period and then dividing said rate by 360 to
determine the daily periodic rate to be applied for each day in the applicable
period. Application of the Actual/360 Computation produces an annualized
effective rate exceeding that of the nominal rate.

                  REPAYMENT TERMS. This Note shall be due and payable in
consecutive monthly payments of accrued interest only commencing on July 1,
1998, and on the first day of each month thereafter until fully paid. In any
event, all principal and accrued interest hereunder shall be due and payable on
the earlier to occur of (i) the day the Revolving Loans are accelerated due to
the occurrence of a Default, or (ii) December 31, 1999 (the "Maturity Date").

                  MANDATORY PREPAYMENTS. Upon the receipt of Net Cash Proceeds
(as defined below) from any sale or issuance of any shares of Borrower's common
stock or any class of its preferred stock, any securities convertible into or
exchangeable for shares of any such stock, or any warrants, rights or options to
acquire shares of such stock, Borrower will prepay the Obligations in an amount
equal to 100% of such Net Cash Proceeds, and (notwithstanding any provision of
this Note or any other Loan Document) such prepayment shall be applied in the
following manner:

                  FIRST: to pay the principal balance of any outstanding
Revolving Loans (defined herein), together with any accrued and unpaid interest
thereon, and SECOND to pay the principal balance of any outstanding Revolving
Loans incurred under the Credit Agreement (defined herein), together with any
accrued and unpaid interest thereon.

                  The maximum amount available to be advanced under this Note
shall be permanently reduced by an amount equal to the amount applied to reduce
the principal balance of the Revolving Loans pursuant to clause First above. As
used herein "Net Cash Proceeds" means the aggregate amount of cash received from
time to time (whether as initial consideration a through payment or disposition
of deferred compensation) by or on behalf of Borrower in connection with any
sale or issuance of equity securities contemplated above, after deduction
therefrom only (i) reasonable and customary brokerage commissions, underwriting
fees and discounts, legal fees and other similar fees and expenses, and (ii) the
amount of taxes payable in connection with, or as a result of, such transaction;
but in each case only to the extent that such amounts are deducted upon receipt
of such cash proceeds and actually paid to persons or entities, 



                                      -3-
<PAGE>   4

other than Borrower, Note Guarantors or any Affiliate of Borrower or Note
Guarantors. For the avoidance of doubt, Borrower acknowledges that (i) the
foregoing shall not be deemed or construed as a consent by Bank to any such
equity sale or issuance which would otherwise be prohibited by the terms of the
Loan Documents and (i) this Section, as it relates to the reduction of
Borrower's Obligations under the Credit Agreement, shall survive the payment in
full and/or termination of Borrower's Obligations hereunder. In connection with
any prepayment required hereunder, Bank shall cooperate with Borrower to
mitigate any Indemnified Loss of Expense otherwise payable hereunder and similar
charges payable under the Credit Agreement.

                  APPLICATION OF PAYMENTS. Monies received by Bank from any
source for application toward payment of the Obligations shall be applied first
to fees, penalties, accrued interest and then to principal. If a Default occurs,
monies may be applied to the Obligations in any manner or order deemed
appropriate by Bank. If any payment received by Bank under this Note or other
Loan Documents is rescinded, avoided or for any reason returned by Bank because
of any adverse claim or threatened action, the returned payment shall remain
payable as an obligation of all persons liable under this Note or other Loan
Documents as though such payment had not been made.

                  LOAN DOCUMENTS AND OBLIGATIONS. The term "Loan Documents" used
in this Note and other Loan Documents refers to all documents executed in
connection with the loan evidenced by this Note and any prior notes which
evidence all or any portion of the loan evidenced by this Note, and may include,
without limitation, this Note, the TJR Documents, the Credit Agreement (as such
term is defined below), guaranty agreements, security agreements, security
instruments, financing statements, mortgage instruments, letters of credit and
any renewals or modifications, whenever any of the foregoing are executed, but
does not include swap agreements (as defined in 11 U.S.C. ss. 101).

                  The term "Obligations" used in this Note refers to any and all
indebtedness and other obligations under this Note, all other obligations under
any other Loan Document(s), and all obligations under any swap agreements as
defined in 11 U.S.C. ss. 101 between Borrower and Bank whenever executed.

                  LATE CHARGE. If any payments are not timely made, Borrower
shall also pay to Bank a late charge equal to 3% of each payment past due for 10
or more days. Acceptance by Bank of any late payment without an accompanying
late charge shall not be deemed a waiver of Bank's right to collect such late
charge or to collect a late charge for any subsequent late payment received.

                  ATTORNEYS' FEES AND OTHER COLLECTION COSTS. Borrower shall pay
all of Bank's reasonable expenses incurred to enforce or collect any of the
Obligations, including, without limitation, reasonable arbitration, paralegals',
attorneys' and experts' fees and expenses, whether incurred without the
commencement of a suit, in any trial, arbitration, or administrative proceeding,
or in any appellate or bankruptcy proceeding.

                  USURY. Regardless of any other provision of this Note or other
Loan Documents, if for any reason the effective interest should exceed the
maximum lawful interest, 



                                      -4-
<PAGE>   5

the effective interest shall be deemed reduced to, and shall be, such maximum
lawful interest, and (i) the amount which would be excessive interest shall be
deemed applied to the reduction of the principal balance of this Note and not to
the payment of interest, and (ii) if the loan evidenced by this Note has been or
is thereby paid in full, the excess shall be returned to the party paying same,
such application to the principal balance of this Note or the refunding of
excess to be a complete settlement and acquittance thereof.

                  DEFAULT. If any of the following occurs, a default ("Default")
under this Note shall exist: NONPAYMENT; NONPERFORMANCE. The failure of timely
payment or performance of the Obligations or Default under this Note or any
other Loan Documents or failure of any party to comply with any other term,
condition or agreement set forth in this Note or any other Loan Document, beyond
any applicable grace period, if any. FALSE WARRANTY. A warranty or
representation made or deemed made in the Loan Documents or furnished Bank in
connection with the loan evidenced by this Note proves materially false, or if
of a continuing nature, becomes materially false. CROSS DEFAULT. At Bank's
option, any default in payment or performance of any obligation under any other
loans, contracts or agreements of Borrower, any Subsidiary or Affiliate of
Borrower, any general partner of or the holder(s) of the majority ownership
interests of Borrower with Bank or its affiliates ("Affiliate" shall have the
meaning as defined in 11 U.S.C. ss. 101, except that the term "debtor" therein
shall be substituted by the term "Borrower" herein; "Subsidiary" shall mean any
corporation of which more than 50% of the issued and outstanding voting stock is
owned directly or indirectly by Borrower). CESSATION; BANKRUPTCY. The
dissolution of, termination of existence of, loss of good standing status by,
appointment of a receiver for, assignment for the benefit of creditors of, or
commencement of any bankruptcy or insolvency proceeding by or against the
Borrower, its Subsidiaries or Affiliates, if any, or any general partner of or
the holder(s) of the majority ownership interests of Borrower, or any party to
the Loan Documents. NOTE GUARANTORS. If (i) any Note Guarantor fails to comply
with any payment obligation set forth in the Guaranty or if any Note Guarantor
fails to comply with any of the covenants or other agreements set forth in the
Guaranty or any other Loan Document to which it is a party beyond any applicable
grace period provided for therein, or (ii) any representation or warranty made
or deemed made by Note Guarantor in the Guaranty or any other Loan Document to
which it is a party or which is contained in any exhibit, schedule or any other
document or other statement furnished at any time under or in connection with
the Guaranty or any of the other Loan Documents shall prove to have been
incorrect in any material respect on or as of the date made or deemed made, or
(iii) if Note Guarantor shall terminate, purport to terminate or take any steps
which have the effect of decreasing its liability under the Guaranty.





                                      -5-
<PAGE>   6

                  REMEDIES UPON DEFAULT. If a Default occurs under this Note or
any Loan Documents, Bank may at any time thereafter, take the following actions:
BANK LIEN. Foreclose its security interest or lien against Borrower's accounts
without notice. ACCELERATION UPON DEFAULT. Accelerate the maturity of this Note
and all other Obligations, and all of the Obligations shall be immediately due
and payable. CUMULATIVE. Exercise any rights and remedies as provided under the
Note and other Loan Documents, or as provided by law or equity.

                  FINANCIAL AND OTHER INFORMATION. Borrower shall deliver to
Bank such information as required under the Credit Agreement and other Loan
Documents.

                  AUTOMATIC DEBIT OF CHECKING ACCOUNT FOR LOAN PAYMENT. Borrower
authorizes Bank to debit its demand deposit account number 002030000135558 or
any other account with Bank for any payments due under this Note. Borrower
further certifies that Borrower holds legitimate ownership of this account and
preauthorizes this periodic debit as part of its right under said ownership.

                  REVOLVING LOANS. Borrower may borrow, repay and reborrow, and
Bank may advance and readvance under this Note respectively from time to time
(each a "Revolving Loan" and together the "Revolving Loans"), so long as the
total indebtedness outstanding at any one time does not exceed the principal
amount stated on the face of this Note (as such availability may be reduced
pursuant to the Section captioned Mandatory Prepayments hereunder). Bank's
obligation to make Revolving Loans under this Note shall terminate if there is a
Default.

                  ADDITIONAL COVENANTS, REPRESENTATIONS AND WARRANTIES. All of
the agreements, covenants, representations and warranties made by the Borrower
in the Revolving Loan and Security Agreement dated March 31, 1997 between the
Borrower and the Bank as the same may be amended from time to time (the "Credit
Agreement") and the other Loan Documents (as such term is defined in the Credit
Agreement) are deemed incorporated herein in their entirety as if fully and
completely set forth herein. All capitalized terms used herein and not otherwise
defined herein shall have the meanings ascribed to such terms in the Credit
Agreement. For the avoidance of doubt, Borrower acknowledges all terms and
provisions of the Credit Agreement incorporated by reference into this Note
shall be so incorporated as such terms exist as of the date hereof and shall
remain so incorporated herein irrespective of the termination or expiration of
the Credit Agreement.

                  WAIVERS AND AMENDMENTS. No waivers, amendments or
modifications of this Note and other Loan Documents shall be valid unless in
writing and signed by an officer of Bank. No waiver by Bank of any Default shall
operate as a waiver of any other Default or the same Default on a future
occasion. Neither the failure nor any delay on the part of Bank in exercising
any right, power, or remedy under this Note and other Loan Documents shall
operate as a waiver thereof, nor shall a single or partial exercise thereof
preclude any other or further exercise thereof or the exercise of any other
right, power or remedy.

                  Each Borrower or any person liable under this Note waives
presentment, protest, notice of dishonor, demand for payment, notice of
intention to accelerate maturity, notice of 




                                      -6-
<PAGE>   7

acceleration of maturity, notice of sale and all other notices of any kind.
Further, each agrees that Bank may extend, modify or renew this Note or make a
novation of the loan evidenced by this Note for any period and grant any
releases, compromises or indulgences with respect to any collateral securing
this Note, or with respect to any other Borrower or any other person liable
under this Note or other Loan Documents, all without notice to or consent of
each Borrower or each person who may be liable under this Note or other Loan
Documents and without affecting the liability of Borrower or any person who may
be liable under this Note or other Loan Documents.

                  MISCELLANEOUS PROVISIONS.

                           ASSIGNMENT. This Note and other Loan Documents shall
inure to the benefit of and be binding upon the parties and their respective
heirs, legal representatives, successors and assigns. Bank's interests in and
rights under this Note and other Loan Documents are freely assignable, in whole
or in part, by Bank. In addition, nothing in this Note or any of the Loan
Documents shall prohibit Bank from pledging or assigning this Note or any of the
Loan Documents or any interest therein to any Federal Reserve Bank. Borrower
shall not assign its rights and interest hereunder without the prior written
consent of Bank, and any attempt by Borrower to assign without Bank's prior
written consent is null and void. Any assignment shall not release Borrower from
the Obligations. APPLICABLE LAW; CONFLICT BETWEEN DOCUMENTS. This Note and other
Loan Documents shall be governed by and construed under the laws of the state
where Bank first shown above is located without regard to that state's conflict
of laws principles. If the terms of this Note should conflict with the terms of
the loan agreement or any commitment letter that survives closing, the terms of
this Note shall control. BORROWER'S ACCOUNTS. Except as prohibited by law,
Borrower grants Bank a security interest in all of Borrower's accounts with Bank
and any of its affiliates. JURISDICTION. Borrower irrevocably agrees to
non-exclusive personal jurisdiction in the state in which the office of Bank
first shown above is located. SEVERABILITY. If any provision of this Note or of
the other Loan Documents shall be prohibited or invalid under applicable law,
such provision shall be ineffective but only to the extent of such prohibition
or invalidity, without invalidating the remainder of such provision or the
remaining provisions of this Note or other such document. NOTICES. Any notices
to Borrower shall be sufficiently given, if in writing and mailed or delivered
to the Borrower's address shown above or such other address as provided
hereunder, and to Bank, if in writing and mailed or delivered to Bank's office
address shown above or such other address as Bank may specify in writing from
time to time. In the event that Borrower changes Borrower's address at any time
prior to the date the Obligations are paid in full, Borrower agrees to promptly
give written notice of said change of address by registered or certified mail,
return receipt requested, all charges prepaid. PLURAL; CAPTIONS. All references
in the Loan Documents to Borrower, guarantor, person, document or other nouns of
reference mean both the singular and plural form, as the case may be, and the
term "person" shall mean any individual, person or entity. The captions
contained in the Loan Documents are inserted for convenience only and shall not
affect the meaning or interpretation of the Loan Documents. BINDING CONTRACT.

recordation and/or similar taxes on this transaction whether assessed at closing
or arising from time to time.

                  ARBITRATION. Upon demand of any party hereto, whether made
before or after institution of any judicial proceeding, any dispute, claim or
controversy arising out of, connected with or relating to this Note and other
Loan Documents ("Disputes") between or among parties to this Note shall be
resolved by binding arbitration as provided herein. Institution of a judicial
proceeding by a party does not waive the right of that party to demand
arbitration hereunder. Disputes may include, without limitation, tort claims,
counterclaims, disputes as to whether a matter is subject to arbitration, claims
brought as class actions, claims arising from Loan Documents executed in the
future, or claims arising out of or connected with the transaction reflected by
this Note.

                  Arbitration shall be conducted under and governed by the
Commercial Financial Disputes Arbitration Rules (the "Arbitration Rules") of the
American Arbitration Association (the "AAA") and Title 9 of the U.S. Code. All

first stated above is located. The expedited procedures set forth in Rule 51 ET
SEQ. of the Arbitration Rules shall be applicable to claims of less than
$1,000,000.00. All applicable statutes of limitation shall apply to any Dispute.
A judgment upon the award may be entered in any court having jurisdiction. The
panel from which all arbitrators are selected shall be comprised of licensed
attorneys. The single arbitrator selected for expedited procedure shall be a
retired judge from the highest court of general jurisdiction, state or federal,
of the state where the hearing will be conducted or if such person is not
available to serve, the single arbitrator may be a licensed attorney.
Notwithstanding the foregoing, this arbitration provision does not apply to
disputes under or related to swap agreements.

                  PRESERVATION AND LIMITATION OF REMEDIES. Notwithstanding the
preceding binding arbitration provisions, Bank and Borrower agree to preserve,
without diminution, certain remedies that any party hereto may employ or
exercise freely, independently or in connection with an arbitration proceeding
or after an arbitration action is brought. Bank and Borrower shall have the
right to proceed in any court of proper jurisdiction or by self-help to exercise
or prosecute the following remedies, as applicable: (i) all rights to foreclose
against any real or personal property or other security by exercising a power of
sale granted under Loan Documents or under applicable law or by judicial
foreclosure and sale, including a proceeding to confirm the sale; (ii) all
rights of self-help including peaceful occupation of real property and
collection of rents, set-off, and peaceful possession of personal property;
(iii) obtaining provisional or ancillary remedies including injunctive relief,
sequestration, garnishment, attachment, appointment of receiver and filing an
involuntary bankruptcy proceeding; and (iv) when applicable, a judgment by
confession of judgment. Preservation of these remedies does not limit the power
of an arbitrator to grant similar remedies that may be requested by a party in a
Dispute.

                  "10.14 Financial Covenants.



                  (a) FIXED CHARGE RATIO. Borrower shall not permit the Fixed
         Charge Coverage Ratio to be less than 1.2 to 1 at the end of any fiscal
         quarter commencing with the fiscal quarter ending March 31, 1999.

                  (b) EFFECTIVE TANGIBLE NET WORTH. The Borrower shall maintain
         an Effective Tangible Net Worth (i) as at September 30, 1998 of not
         less than $10,000,000.00 , (ii) as at December 31, 1998 of not less
         than $29,000,000.00, (iii) as at March 31, 1999 of not less than
         $29,000,000.00 and (iv) as at May 15, 1999 and all times thereafter of
         not less than $54,000,000.00. "Effective Tangible Net Worth" means
         total assets MINUS total liabilities as determined in accordance with
         GAAP, applied on a consistent basis. For purposes of this computation,
         the aggregate amount of any assets classified as Intangibles shall be
         subtracted from total assets and total liabilities shall not include
         the Borrower's obligations with respect to the New Preferred Stock to
         the extent that such obligations are otherwise classified as
         liabilities of the Borrower in accordance with GAAP."

                  (c) Section 10.21 of the Loan Agreement is amended and
restated to read as follows:

                  "10.21 DIVIDENDS. The Borrower shall not declare any dividends
         (other than dividends payable solely in stock of Borrower) on, or make
         any payment on account of , any shares of any class of stock of the
         Borrower, whether now or hereafter outstanding, or make any other
         distribution in respect thereof, either directly or indirectly, whether
         in cash or property or in obligations of the Borrower, or make any
         payment on account of, or purchase or otherwise acquire, any securities
         of the Borrowers from any Person; provided, however that the foregoing
         shall not prohibit the Borrower from paying or declaring dividends in
         respect of the New Preferred Stock of (i) not greater than 2% per share
         (and $434,000.00 in the aggregate per annum) whether paid in cash or
         in-kind, in the form of scheduled dividends on such preferred stock,
         and (i) not greater than 0.5% per share (and $108,750 in the aggregate
         per annum) in cash in the form of a special dividend payment incidental
         to the Borrower's failure to timely file and maintain in effect the
         "Shelf Registration" in accordance with the terms of such preferred
         stock, in each case, if, AND ONLY IF, afer giving effect to the payment
         of any such dividends, no Event of Default or Unmatured Event of
         Default would then exist."

                  (d) Immediately following Section 10.27 of the Loan Agreement
there shall be inserted a new Section 10.28, which shall read as follows:

                  "10.28 YEAR 2000 COMPATIBILITY. The Borrower shall take all
         action necessary to assure that its computer based systems have the
         ability to operate and effectively process data including dates on or
         after January 1, 2000. The Borrower shall make further inquiry as to
         its significant suppliers and customers regarding their respective
         efforts to assure such Year 2000 compatibility. At the request of the
         Bank, the Borrower 




                                       8

         shall provide the Bank with such assurances as it may reasonably
